PART I

ITEM 1. BUSINESS.

General

Our Mission

Our mission is to create enterprise-grade technology for small and medium businesses ("SMBs") delivered through our growing, global network of managed service provider ("MSP") partners.

Overview

Datto Holding Corp. ("Datto Holding", "Datto", “we,” “us,” “our” and “the Company”) is the leading global provider of security and cloud-based software solutions purpose-built for delivery through the MSP channel to SMBs. MSPs represent the future of information technology ("IT") management for SMBs. Digital transformation is driving SMB adoption of modern software and technology, while regulatory and data protection requirements and proliferating security threats are increasing the complexity and risk of IT for SMBs. These trends have created an inflection point in SMB outsourcing to MSPs for IT management. MSPs are equipped with the IT resources and expertise SMBs lack, serving as a single provider to meet all of an SMB’s IT needs. MSPs are trusted to select, procure, implement and manage software and technology stacks that support their SMB customers’ business needs. The number of MSPs continues to grow, with approximately 132,000 MSPs providing this critical function to millions of SMBs worldwide today.

We are committed to the success of MSPs. It is the foundation of our strategy and culture. We empower our MSP partner channel, creating enormous sales and support leverage for us to efficiently address the large but fragmented SMB IT market. Our MSP-centric platform enables our partners to generate recurring revenue through the sale of our solutions to SMBs and to scale and effectively manage their own businesses. Our relationships are directly with our MSP partners. We are the leading pure-play vendor serving the MSP market, and believe our MSP-centric approach is highly differentiating as it aligns our mutual incentives, creates a motivated and engaged sales channel and reinforces our position as an integral component of our MSP partners’ businesses.

Our cloud-based offerings include Unified Continuity, Networking, Endpoint Management and Business Management software solutions. Our Unified Continuity, Networking and Endpoint Management offerings ensure the ongoing availability and security of mission-critical IT systems for SMBs in both private and public clouds. These solutions are simple for MSPs to deploy, configure and manage across their SMB customers through a single portal. Our Business Management software provides critical operational tools to MSPs for efficient workflow management and delivery of end-to-end managed services. Our platform also includes a host of business development tools, training and content to help MSPs address the challenges of marketing and selling to SMB customers.

We employ a land-and-expand business model and grow as our MSP partners grow. We seek to deliver tools and resources that are easy to adopt and enable recurring revenue growth and margin efficiency for our MSP partners. Our partners can expand their footprint with us on a frictionless basis as they increase the number of SMB customers they serve, they expand the number of Datto products that they sell through to their SMB customers, or their SMB customers add employees, applications and endpoints. As of December 31, 2021 and 2020, our dollar-based net retention rate was 116% and 111%, respectively. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Performance Metrics” for additional information regarding our dollar-based net retention rate.

We have a highly efficient go-to-market model, in which we leverage our sales force and the power of our brand to attract, retain and grow our MSP partners. As of December 31, 2021, we had over 18,500 MSP partners, of which over 1,400 accounted for annual run-rate revenue, or ARR, of $100,000 or more each. MSP partners with over $100,000 of ARR accounted for 49% of our total ARR as of December 31, 2021. As of December 31, 2021 our 10 largest partners represented approximately 3% of our ARR and no single partner represented more than 0.5% of our ARR. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Performance Metrics” for additional information regarding ARR.

Our business has experienced rapid growth since inception and generates revenue that is highly recurring. As of December 31, 2021, our ARR was $658.4 million and our revenue for the year ended December 31, 2021 was $618.7 million, of which approximately 93% was recurring subscription revenue. As of December 31, 2020, our ARR was $542.8 million and our revenue for the year ended December 31, 2020 was $518.8 million, of which approximately 94% was recurring subscription revenue. For the year ended December 31, 2021, our net income was $51.4 million and our Adjusted EBITDA, which we define as net income (loss) adjusted for interest and other expense, net, loss on extinguishment of debt, depreciation and amortization, provision for (benefit from) income tax, stock-based compensation expense, restructuring expense and transaction related and other expense, was $175.4 million. For the year ended December 31, 2020, our net income was $22.5 million and our Adjusted EBITDA was $150.5 million. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Financial Measures—Adjusted EBITDA” for additional information regarding Adjusted EBITDA.

Industry Background

MSPs represent the future of IT management for SMBs. As dedicated technology experts, MSPs are equipped with the IT resources and expertise SMBs lack, providing a single source to meet all of an SMB’s IT needs. MSPs are trusted to select, procure and implement software and technology stacks for their SMB customers. After implementation, MSPs provide ongoing value to SMBs through strategic guidance, technical support, monitoring and maintenance of their full IT environments.

A number of industry and technology trends are greatly increasing the complexity of the IT challenges faced by SMBs, leading SMBs to outsource their IT management to MSPs. These trends include:

•SMBs are increasingly adopting digital and cloud-based technologies. In response to competitive pressures and the demands of customers and employees, businesses are increasingly adopting digital and cloud-based technologies to help them transform their operations and compete in the marketplace. Even traditionally offline businesses are increasingly embracing technology to help them more efficiently market to, transact with and support customers, as well as to run their own operations. With the democratization of technology, SMBs are under pressure to adopt digital solutions with enterprise-grade capabilities or risk being disrupted by their competitors. We believe that new business challenges arising from the novel Coronavirus Disease 2019 ("COVID-19") pandemic contributed to the acceleration of the digital transformation of SMBs. According to the International Data Corporation's ("IDC") Worldwide Small and Medium-Sized Business 2022 Predictions, 70% of SMBs will have significantly increased their IT spending by 2026 in order to become more digitally resilient and capitalize on changed market conditions. IDC also predicted that by 2024, 75% of start-ups will have a digital-first strategy, either adopting next-generation technologies, placing high emphasis on innovation, or focusing on digital disruption.

•Modern technologies are driving complexity in IT. The accelerating pace of technological advancement and proliferation of software and technology offerings are increasing the difficulty for businesses to evaluate, select and implement an optimal IT environment. With the adoption of modern technologies, IT systems have become increasingly linked to business operations and to each other through complex integrations, greatly heightening the importance of effective IT management.

•SMB exposure to security and regulatory risk is increasing. SMBs are increasingly collecting, generating and storing data to perform mission-critical functions. Recognizing the criticality and potential value of this data, bad actors are increasingly targeting SMBs to exploit their perceived security vulnerabilities. According to IDC, by 2024, 33% of SMBs will experience security breaches quarterly, causing business disruptions of at least one week per quarter. Moreover, SMB data is potentially subject to a variety of ever-evolving regulatory regimes, creating the additional challenge of ensuring ongoing compliance.

•SMBs are not equipped to meet the expanding challenges of IT management. Despite requiring certain capabilities of enterprise-grade technology solutions, SMBs lack the time, resources and expertise to deploy, manage and maintain an enterprise-grade IT stack. SMBs historically have been unable to attract or retain sufficient in-house IT resources. This problem has only been exacerbated with the recent trend of technology professional labor shortages. Grappling with the day-to-day management of IT also takes time and resources away from advancing core business goals.

•The costs of downtime or data loss are meaningful and expanding. With increasingly digital operations, system downtime or data loss can result in lost revenue, customer churn, negative brand perception and reduced employee productivity. For SMBs, these losses could be catastrophic, with the potential to result in significant business disruptions or even bankruptcy, driving the need for comprehensive and effective enterprise-grade continuity solutions.

Our Differentiated Approach

We are committed to the success of MSPs. It is the foundation of our strategy and culture. We believe our MSP-centric approach is highly differentiating because it aligns our mutual incentives, creates a motivated and engaged sales channel and ensures we become an integral component of our MSP partners’ businesses. Our approach, combined with our expansive platform, has helped to establish us as the leading pure-play vendor serving the MSP market, with an extensive network of more than 18,500 MSP partners. We empower our MSP partner channel, creating enormous sales and support leverage for us to efficiently address the large, but fragmented, SMB IT market.

Our Unified Continuity, Networking and Endpoint Management solutions generate recurring revenue for MSPs as part of their managed services for SMBs. MSPs integrate these solutions into managed services that they offer to their SMB customers on their own terms, including pricing, packaging, billing and solution-bundling, giving MSPs greater control over growth and profitability of their managed services. We also provide visibility and predictability to our MSP partners by delivering our solutions on a subscription basis.

Our Business Management offerings further this overall value proposition, enabling MSPs to scale and optimize the workflows and business processes associated with managed services delivery. Our solutions are purpose-built to address the specific needs of MSPs, enabling them to improve customer satisfaction, increase productivity, decrease response times and reduce costs, enhancing the overall profitability of their businesses.

Table of Contents

Our platform also features business development tools and content to help MSPs address the challenges of marketing and selling to SMBs. We do not directly market or sell to SMBs to avoid competing with our MSP partners. Instead, we offer MSPs tools for marketing automation and content for marketing programs, as well as training and certifications. We further cultivate the broader MSP ecosystem through our thought leadership efforts and industry-leading events. Our open ecosystem events, such as DattoCon and MSP Technology Days, are among the largest MSP events in the world.

Our singular dedication to our partners has enabled us to create a network of more than 18,500 MSPs that rely upon Datto solutions to serve over 1.5 million SMBs, in each case as of December 31, 2021. Our model of distribution through this network of MSPs mitigates the challenges of addressing the SMB market and provides us with the following benefits:

•Sales leverage. The MSP channel creates enormous sales leverage for us to address the large but fragmented SMB IT market. With each of our sales representatives capable of reaching dozens of MSPs, who in turn can serve hundreds of SMBs, the reach of our sales force is greatly amplified.

•Recurring revenue durability. Our direct contractual relationships with MSP partners insulate us from SMB churn from bankruptcy, consolidation or other adverse events. In the event of SMB customer loss, the associated MSP will often maintain their revenue stream by migrating that customer’s Datto stack to a different customer.

•Natural revenue expansion. Once we are engaged with an MSP, our revenue expands naturally as that MSP adds existing and new SMB customers to our platform, those SMBs add new employees, applications and endpoints, the MSP upgrades service tiers or purchases more of our solutions to meet growing data protection or networking needs and the MSP cross-sells additional Datto solutions into its customer base.

•Support and service leverage. We provide 24/7 direct-to-tech support to our MSP partners, who are responsible for providing higher touch implementation and ongoing support services to their SMB customers. This approach allows us to avoid the significant cost associated with providing support and service activities to over 1.5 million SMBs.

Key Strengths of Our Solutions

Datto is the largest pure-play vendor serving the MSP market with a unified, cloud-based platform that enables the end-to-end delivery of managed IT services to SMBs. Our platform combines mission-critical software, technologies and security solutions that MSPs sell to SMBs, and business management software to help MSPs scale and grow their own businesses. Our solutions include Unified Continuity, Networking, Endpoint Management and Business Management.

Unified Continuity Solutions

Unified Continuity constitutes a suite of security and cloud-based software solutions, including business continuity and disaster recovery, or BCDR, and SaaS Protection +. These products provide enterprise-grade data protection, ensure business uptime and establish a last line of defense against security threats by enabling the full image backup, virtualization, cloud replication and restoration of entire physical or virtual servers and PCs, whether on-premise at an SMB, remotely in a data center or in the cloud. The key differentiators of our Unified Continuity solutions include:

•Built for MSPs. We provide turnkey solutions that are remotely configurable and easy to deploy. Once deployed, data automatically begins flowing into the private Datto cloud platform, or the Datto Cloud, and can be managed through the Datto partner portal, which provides MSPs with a multi-tenant view of all their SMB customers.

•Comprehensive protection for the full IT environment. Our solutions provide comprehensive protection of data and applications to efficiently prevent data loss, mitigate ransomware attacks and minimize downtime for MSPs’ SMB customers. This includes the ability to protect and quickly restore full physical, virtual or cloud environments to any point in time, in a hardware-agnostic manner, as well as the ability to seamlessly protect and recover data from public cloud SaaS applications. Our solutions are often a last line, comprehensive defense when an SMB's firewalls are breached or a network is compromised.

•Highly reliable and performant. Our solutions replicate environments across multiple locations to create redundancy and ensure partner-managed environments are fully protected. Our solutions continually validate that these environments can be fully restored through multiple layers of verification, including automated ransomware scanning, disk and service integrity checks and testing of the virtual machine. In an adverse event, our solutions are capable of providing near-instantaneous virtualization in our cloud, temporary failover and high-performance recovery to the local network to ensure ongoing continuity of the SMB’s systems, minimizing costly downtime.

Networking Solutions

Networking refers to our collection of integrated WiFi access points and connectivity offerings that enable MSPs to efficiently offer highly reliable and performant cloud-managed networking to their SMB customers. The key differentiators of our Networking solutions include:

•Built for MSPs. Our networking solutions are purpose-built to align with the needs of MSPs in delivering managed networking. Our solutions enable remote monitoring and management from the cloud, providing MSPs with a multi-tenant view of all networks and connected devices, with automated event alerts and visual indicators of each device’s status. They also enable efficient management through seamless native integration with critical MSP tools.

•Efficient deployment. Our solutions allow MSPs to preconfigure customer network settings, enabling the plug-and-play self-formation of entire networks. Configurations can be cloned from similar existing networks, enabling MSPs to quickly and easily deploy new customer networks in a standardized and pre-defined manner.

•Highly reliable and performant. Our solutions are specifically designed to provide highly reliable and performant networking to help MSPs maximize uptime for SMB customers. Our networking solutions feature automatic failover and failback, self-healing mesh and channel scanning mechanisms to ensure customer networks maintain and optimize performance, even in the event of a disruption to primary connections or hardwired network lines.

Endpoint Management Solutions

Endpoint Management refers to our cloud-based Remote Monitoring and Management, or RMM, platform and the critical operational tools it provides for MSPs to remotely manage and protect a complete spectrum of their SMB customers' endpoints. The key differentiators of our Endpoint Management solutions include:

•Built for MSPs. Our endpoint management solutions allow MSPs to proactively and reactively remediate a wide variety of IT issues on their SMB customers' endpoints remotely. Our RMM is easy to deploy and gives MSPs a single centralized hub to manage and protect endpoints across all of their SMB customers.

•Cloud native with embedded security features. Our endpoint management solutions are cloud native and have embedded security automation tools including antivirus management, patch management, application management, encryption control, continuity integration, and ransomware detection. Datto RMM has been assessed under the Building Security In Maturity Model ("BSIMM") standards and its maturity was found to be among the best of all companies and products assessed.

•Complete visibility and control. Our endpoint management solutions provide MSPs with full visibility into SMB customer environments across PCs, servers and networks, with complete control to remotely remediate IT issues. Configurable dashboards, alerts and automations help MSPs efficiently deliver managed IT services.

Business Management Solutions

Business Management refers to our suite of integrated SaaS products for MSPs, including Autotask Professional Services Automation, or PSA, and Datto Commerce, that provide critical operational tools to manage workflows and the delivery of end-to-end IT services. Built from inception to run in the cloud, these offerings allow MSPs to manage their businesses through a centralized hub and to increase operational efficiency. The key differentiators of our Business Management solutions include:

•Built for MSPs. Our business management solutions provide a fully integrated solution for single pane of glass management of the critical operational workflows and business processes of MSPs, including ticketing, project management, customer relationship management, quoting, procurement, invoicing, inventory management and resource management. Our solutions offer embedded integrations with over a hundred other MSP tools and technologies for the seamless and efficient delivery of managed services.

•Cloud and mobile enabled. Our business management solutions are cloud native and include mobile device support, enabling the efficient and effective management of IT service delivery. With mobile-enabled solutions, technicians can access critical tools and systems from the field, increasing productivity and reducing costs.

•Robust business intelligence. Our business management solutions provide configurable dashboards, alerts, actionable insights, analytics and automation to help MSPs drive operational efficiency.

Key Benefits to Our MSP Partners

MSPs choose Datto and develop longstanding relationships with us not only for our innovative solutions but also for our comprehensive platform, which delivers the following key benefits to our MSP partners:

Table of Contents

•Enable shift to managed IT services. By providing solutions specifically designed for delivery in a bundled suite of critical managed services, we facilitate the shift of IT services organizations to a recurring managed services model. With our platform, MSPs generate recurring revenue through the sale of our software and technology to SMBs on a subscription basis and thereby gain clear visibility into and predictability of revenue. Our suite of products provides our MSP partners with multiple avenues to land new customers and expand recurring revenue over time.

•Increase retention of SMB customers. Any time an SMB experiences a security downtime or data loss event, an MSP runs the risk of losing that customer. For this reason, MSPs seek reliable solutions that reduce the risk of SMB downtime and data loss. With our solutions, MSPs gain a last line of defense against security threats that ensures ongoing availability and comprehensive data protection, providing their SMB customers with peace of mind. Datto solutions have proven to be very reliable for MSP partners in enabling the efficient management of their customer base, preventing downtime and recovering from cyberattacks and data loss events. As a result, the MSP’s role in securing SMBs’ mission-critical systems solidifies the MSP’s importance as a trusted partner to SMBs.

•Increase profit generation from SMB customers. Our solutions are competitively priced to enable our MSP partners to generate attractive profit margins. The pricing of our solutions for MSPs is generally based on a predetermined tier for a given solution, ensuring our MSP partners have visibility into delivery cost. The pricing of our solutions is not available to SMBs and our MSP partners have latitude to set the pricing, packaging and bundling of our solutions as a managed offering to their customers. As a result, our MSP partners can leverage our solutions to create reliable profit centers for their businesses.

•Avoid channel conflict. Unlike most technology and software vendors who sell to both MSPs and SMB customers, Datto does not compete with MSPs. Datto’s MSP-centric approach enables us to focus solely on the needs of MSPs, designing our platform and solutions for this market. We provide MSPs with the tools and support they need to create and sell managed services to their SMB customers and the assurance we will not compete directly for the business of SMBs.

•Reduce the cost of managing SMB customer IT environments. Our remote monitoring and management product enables the delivery of end-to-end managed IT services by allowing MSPs to perform proactive monitoring, preventative maintenance and remote remediation of customer systems, applications and devices in real-time with intelligent alerting, auto-response and auto-resolution. Our cloud-based solutions help MSPs achieve better resource utilization by reducing costly truck rolls for on-site service and freeing up resources to pursue higher value activities.

•Enable operational efficiency. Our business management tools are easy to implement and use, enabling MSPs to operate their own businesses more efficiently through centralized operations from a single pane of glass. These software solutions are optimized for the business needs of MSPs to enable workflow automation and deliver actionable insights, providing full visibility into customer IT environments. Our solutions have embedded integrations with other Datto products and other services and technologies to make it easier for an MSP to manage a heterogeneous technology stack.

•Drive business growth. In addition to our products, our platform also includes a range of sales and marketing content, training and other programs as well as technical certifications tailored to our MSP partners to help them more effectively grow their businesses, alleviating a major pain-point for IT professionals with limited sales and marketing experience.

Our Growth Strategy

We pursue numerous actions to drive our growth in subscription revenue. Key elements of our growth strategy include:

•Expand our partner base by adding new MSPs. We believe that there is substantial opportunity to increase our penetration among MSPs. We intend to continue leveraging the strong awareness of our brand as a trusted partner to the MSP community to add new MSPs in the markets we serve. We have expanded our MSP partner base from approximately 17,000 at December 31, 2020 to over 18,500 at December 31, 2021.

•Standardize MSP partners on our platform. Once an MSP partner joins our platform, our goal is to increase the penetration of our solutions across its existing SMB customer base. Typically, MSPs initially deploy our solutions to only a limited number of their SMB customers. Over time, MSPs often continue to migrate additional existing end-customers to our platform for the benefit of managing a single integrated solution stack. We aim to aid in this migration in order to increase our overall penetration into our MSP partners’ existing SMB customer base.

•Empower our MSP partners to attract more SMBs. As SMBs increasingly rely on MSPs for IT management, we seek to grow our revenue by helping our existing MSP partners attract additional SMB customers that may ultimately adopt our solutions. We plan to continue developing marketing automation tools and content for marketing, as well as offering training and certifications, in order to facilitate our MSP partners’ growth.

•Facilitate upsell and cross-sell activity with our MSP partners and their SMB customers. We intend to grow our sales teams in order to increase our sales with our MSP partners. Our sales teams upsell our MSP partners to higher service tier subscriptions as the data retention and bandwidth needs of their SMB customers grow. Upsell activity can also occur every time our MSP partners' SMB customers add new employees, applications or endpoints, expanding the addressable subscription scaling units for our products. In addition, our sales teams upsell our MSP partners to increase their Business Management subscriptions as they grow. Our sales teams also actively cross-sell our products to our MSP partners, leveraging their positive experiences with our platform. Our dollar-based net retention rate, which was 116% as of December 31, 2021 and 111% as of December 31, 2020, demonstrates our ability to expand within existing MSP partners.

•Extend our product leadership and introduce new platform solutions. We continue to invest in new purpose-built product and service offerings to anticipate and meet the evolving demands of our MSP partners and their SMB customers. We will also continue to pursue opportunistic mergers and acquisitions to complement and enhance our current solution set.

•Expand our international footprint. We believe there is significant opportunity to expand into new international geographies, with approximately 70% of our revenue coming from the United States ("U.S.") in 2021. The maturity of the international SMB IT landscape varies; more mature markets represent growth opportunities in the near term, while less mature markets present a longer-term opportunity as MSPs develop within those markets.

Our Products

Our products include offerings in Unified Continuity, Networking, Endpoint Management and Business Management.

Unified Continuity Products

Datto Unified Continuity is a complete line of products that protect workloads — data, applications and configurations — located on laptops, workstations, physical and virtual servers and in the public cloud. Our suite of cloud-based products protect and restore workloads, reduce SMB downtime resulting from data or system loss and provide a last line of defense against security threats. These products include:

Business Continuity and Disaster Recovery ("BCDR"). MSPs use our all-in-one BCDR products to efficiently protect servers and workstations and minimize downtime for SMBs. SIRIS, Datto’s flagship cloud-managed BCDR product, consists of a state-of-the-art physical or virtual device deployed by MSPs at a customer location or in a private data center, the agent software installed on protected servers and workstations and a cloud-based storage, virtualization and management system. SIRIS is available in service tiers ranging from one to 100 terabytes with a variety of data retention options.

Once an MSP deploys SIRIS, the agent software automatically transfers disk images of the protected machines to the SIRIS device at configurable intervals, as frequently as every five minutes. SIRIS verifies the integrity of every image and transfers a copy of that image to the secure Datto Cloud at selected intervals. In this manner, SIRIS establishes a last line of defense for all protected servers and workstations. In the event of a server or workstation security incident or outage, users can initiate a boot of the virtual image of the affected machines either in the SIRIS device or in the Datto Cloud in as little as six seconds.

In addition to SIRIS, BCDR products also include ALTO, a smaller capacity BCDR solution. Available in 2 terabyte and smaller capacity models, ALTO provides many of the same capabilities of SIRIS without local virtualization on the device. The same agents are used to collect server or workstation images and ALTO is managed from the same management portal in the Datto Cloud, but with ALTO all failover virtualization occurs only in the Datto Cloud.

Datto Continuity for Microsoft Azure ("DCMA"). Datto Continuity for Microsoft Azure is an extension of Datto's flagship BCDR product line, focused squarely on protecting data in Microsoft's public cloud. This first-of-its-kind product uses Datto's industry leading technology, but is built and deployed natively in the cloud. DCMA delivers full platform independence from Microsoft, superior insulation from ransomware attacks, elimination of single cloud outage risk, and true business continuity to minimize the potential for downtime. Datto delivers this new technology with its familiar approach for MSPs: a fixed, predictable monthly price (e.g., no egress fees), an integrated and intuitive single user interface that enables on-premise, private cloud and public cloud workloads to be easily operated together as a hybrid cloud, and 24x7 technical support for our MSP partners.

Cloud Continuity. Cloud Continuity is an extension of Datto's flagship BCDR product line with a focus on the PC market. The COVID-19 pandemic fueled growth of the PC market over the last two years and has significantly expanded this market opportunity. This product line marries the core Datto all-in-one, image-based continuity solution and adds on a key innovation - it replicates data directly to the Datto Cloud, without the need for any hardware or virtual appliance on the local network. In the event of a ransomware attack, device loss or theft, or any other event that impacts the data on the PC, Cloud Continuity allows MSPs to quickly and easily restore the full disk image, or any specific files with a simple recovery approach.

SaaS Protection +. SaaS Protection + includes Datto SaaS Protection and Datto SaaS Defense. Datto SaaS Protection is a reliable, automated and secure backup and restoration product for Microsoft 365 and Google Workspace data. Microsoft and Google currently recommend the use of a third-party backup service because Microsoft 365 and Google Workspace do not directly backup user data. MSPs deploy SaaS Protection seamlessly for their SMB customers in a few simple steps, and can quickly start to take regular backups of user emails, files and sites, storing these backups in the Datto Cloud. MSPs help end-users easily recover from data loss, including ransomware attacks, accidental or malicious deletion and cancelled employee accounts—all from our cloud management portal. Datto SaaS Defense is an advanced threat protection solution that detects zero-day threats at the first encounter. SaaS Defense’s data-independent technology detects unknown threats that other solutions miss by analyzing the composition of an email, chat, or document instead of only scanning for known security threats. SaaS Defense provides robust threat protection for Microsoft 365 applications, including Exchange, OneDrive, SharePoint, and Teams.

Workplace. Datto Workplace is a complete cloud-hosted file sync and share solution enabling end-users to synchronize files across platforms, including mobile devices. Workplace also serves as a collaboration platform allowing users to share and work together on any type of document in its native file format. Centralized cloud management and sophisticated administrative controls at the end-user and group levels give MSPs and their SMB customers control over file governance. Critical business files are also protected via the ransomware detection and management feature, which gives users the ability to immediately revert back to safe file copies from before an infection, undoing the ransomware encryption of user data.

File Protection. Datto File Protection is an MSP-managed, secure and scalable backup product that enables MSPs to efficiently protect and recover files and folders on workstations and laptops of all types. File and folder backups protect unstructured data from ever-present threats such as human error, hardware failure, ransomware and lost or stolen devices. Users can quickly and easily access and restore their own files from the Datto Cloud, enabling them to recover from common data-loss scenarios without raising a support request, or MSPs can securely access customer accounts and restore data on their behalf.

Networking Products

Datto Networking delivers a suite of cloud-managed networking products for MSPs to efficiently deploy to their SMB customers. Networking products currently include:

Access Points. Our WiFi access points deliver high-powered wireless mesh networks with seamless roaming. These 802.11AX access points include quad-core processors to ensure all of the WiFi 6 features have the necessary processing power to deliver the performance required by SMBs.

Switches. We offer switches with 8, 24 and 48 port options, switching capacity ranging from 20 Gbps to 104 Gbps, and mounting options ranging from fanless desktop to rack mounted. MSPs can choose the form factor, performance and mounting options most appropriate for a particular SMB customer.

Edge Routers. Our Edge Routers provide core functionality including intrusion detection and prevention and a firewall with stateful packet inspection, layer 7 DPI, port forwarding, DMZ host and VLAN segregation.

Endpoint Management Products

Datto Endpoint Management consists of a cloud-based platform which enables MSPs to remotely secure, monitor, manage and support their SMB customers' endpoints to reduce costs, protect against cyber threats and increase service delivery efficiency.

Remote Monitoring and Management. A key component of an MSP’s security best practices, Datto RMM is a remote monitoring and management product designed to assist MSPs with their IT service delivery. Built for MSPs as a multi-tenant solution to manage millions of SMB customer endpoints in an efficient manner, Datto RMM is a fully cloud-managed, scalable SaaS product with integrated endpoint ransomware detection. The underlying architecture provides MSPs with the ability to remotely audit, patch, manage, monitor, support and report on SMB customers’ local and public-cloud deployed endpoints. The platform offers a collection of tools for securely supporting thousands of devices without the need for extensive training. MSPs can use Datto RMM tools to create their own scripts, or easily plug in hundreds of pre-made scripts, to automate repetitive tasks like software patching or rapidly respond to security incidents with pre-defined actions. Integrations with Autotask PSA and other frequently-used solutions allow MSPs to seamlessly report on device status, issues and events. Using configurable dashboards, a simple menu system, remote takeover capability and the flexibility to operate from any internet-connected device, Datto RMM helps MSPs deliver better service and increase responsiveness for their SMB customers.

Business Management Products

Datto Business Management consists of integrated SaaS offerings that enable MSPs to be more efficient at scale, including:

Table of Contents

Autotask Professional Services Automation. Autotask PSA is a complete IT business management product that is purpose-built for MSPs and delivers the mission-critical tools an MSP needs to run its business. Continuing to deliver 99.99% uptime in 2021, Autotask PSA pioneered cloud-delivered PSA and provides dashboards that help MSPs turn data into actionable business insights. It enables partners to monitor their sales pipeline, track technician productivity and evaluate customer profitability. It includes device management, ticketing, project management, customer relationship management, invoicing, inventory management and resource management. In addition, our open architecture application programming interface ("API") has enabled more than 200 industry-leading vendors to integrate their business-critical applications with Autotask PSA to further simplify workflows for MSPs. Autotask PSA centralizes business operations and enables quick, data-driven decisions through rich dashboards, customizable alerts and business intelligence tools.

Datto Commerce. Datto Commerce is an intuitive, cloud-based sales platform built for MSPs. It includes quoting, procurement and ecommerce tools for MSPs to drive efficiency and profit margins. The Datto Commerce platform automates procurement with supplier data feeds, allows MSPs to create and send branded quotes to their SMB customers, and provides configurable e-commerce store-fronts for MSPs to offer to their customers. Datto Commerce also integrates with Autotask PSA and other leading PSA platforms and accounting packages.

Our Technology

Unified Continuity, Networking, Endpoint Management and Business Management products are based on a two-level, multi-tenant, private, hybrid cloud architecture. Designed to provide ease of deployment and a high degree of flexibility, our technology enables MSP partners to deliver managed services across a broad range of scenarios at scale.

Key features of our technologies include:

•Easy to use enterprise-grade technology. Our products are designed to be simple to deploy and easy to manage and are built on the latest enterprise-grade technology. This technology includes Type 1 hypervisors, industry-standard scalable monitoring, converged infrastructure and extensive security features. We abstract this complex technology from our MSPs with simple graphical user interfaces. Further, smart defaults and pre-configuration capabilities in our cloud enable MSPs to configure our products, ship them to end-customers and deploy them with minimal effort. Once deployed and configured, our products then connect to the Datto Cloud and begin uploading data. In this way, MSPs can provide secure enterprise-grade technology to their SMB customers without the hassles of deploying, integrating and managing enterprise products.

•Datto product integrations. We pioneered an integrated product portfolio tailored uniquely for MSPs. While Autotask PSA and Datto RMM can be offered as stand-alone products, they are also integrated with each other, allowing technicians to move seamlessly between our PSA and RMM. Integration between Datto RMM and our Networking solutions allows rapid troubleshooting and problem resolution of network issues. Integration between BCDR and PSA allows the PSA to collect and report on deployed devices and manage related support tickets. These integrations encourage MSPs to standardize across our solutions.

•Third-party product integrations. Datto supports an open technology ecosystem for MSPs. MSPs value using different tools from multiple vendors to deliver their managed services, creating unique and often differentiating technology stacks. Datto products are externally integrated with other products to make it easier for an MSP to manage a heterogeneous technology stack. Leveraging open APIs, third party vendors have built more than 200 integrations with our business management products. This includes everything from security tools to competitive remote monitoring and management and professional services automation vendors.

•Two-level multi-tenant architecture. All of our products share a two-tier multi-tenant design, which facilitates MSP management of both their own and the SMBs’ environments. The first tier provides secure resource sharing among MSP partner accounts hosted on the Datto Cloud, while the second tier sits below each MSP account and provides a tenant-centric view of SMB customers for the MSP partner. Most other multi-tenant systems provide only a single level of tenant management.

•Private virtualization and storage cloud. Datto operates its own exabyte scale private cloud which provides us with control over the environment, efficient operating costs and flexibility to best support our partners. The Datto Cloud provides both compute and storage tiers at multiple geographically distributed data centers. This includes the option to replicate a second copy of SMB customer data to an alternative data center in region. We have developed a differentiated virtual machine ("VM") orchestration layer which allows shared management between our MSP partner and the Datto support organization.

•Proprietary work-flow engine. Autotask PSA incorporates a field-configurable business logic engine that allows the implementation of business processes without costly code customization. A single multi-tenant cloud architecture delivers scalable efficient deployment of custom workflows for each MSP partner, and enables partners to trigger actions and alerts based on real time internal data as well as data from third party products. This allows MSPs to deploy PSA to meet the needs of their business, rather than redesigning their business to meet the requirements of their chosen management software.

•Proprietary agent and agentless technology. We have developed several proprietary agents across our product lines, specifically BCDR, RMM and Cloud Continuity. Our Unified Continuity agents protect servers, workstations and PCs by deploying an endpoint resident software package or using an agentless approach for virtual machines and private clouds. We have developed both a robust agent and an agentless plugin that support virtual machine backup on Hyper-V and VMware. We have also developed RMM agents and API integrations that enable MSPs to monitor and manage SMB customer endpoints on premise and in the public cloud. By developing this proprietary technology, we can avoid reliance on third-party licensed backup agents.

•Proprietary remote access technology. Datto RMM incorporates near-instantaneous access to managed endpoints using 100% HTML5 technology with no local plugin required on the managed device. Not only is this technology secure and fast, it delivers cross browser compatibility. This enables technicians to address customer tickets from nearly any browser, including mobile devices and tablets. With better performance than third-party licensed options, Datto RMM also enables MSPs to deliver faster, more responsive service to their SMB customers.

•Proprietary virtual machine image verification technology. Our verification technology provides evidence that backups produced by our BCDR products are viable. This technology performs automated tests on every image for ransomware and disk integrity. “Screenshot” verification boots the virtual machine either on the device or in the cloud and performs additional automated testing for viability. This running instance of the protected virtual machine further allows the MSP partner to utilize our scripting API to run custom test scripts that validate functionality and data integrity beyond what can be normally evaluated through the built-in testing. This functionally is linked back through the multi-tenant portal and alerting system to provide the MSP partner with confirmation that their managed systems are protected.

•Cloud to cloud API-level connectivity. In addition to devices deployed on-premises, the Datto Cloud is designed to ingest data directly from SaaS applications hosted in public clouds. This API-level connectivity brokered through our multi-tenant portal provides the same level of management that our MSP partners expect from the hybrid cloud continuity products. We have worked with Microsoft and Google to make efficient use of Microsoft 365 and Google Workspace APIs and achieve efficient data ingest and restore services.

•Proprietary remote synchronization technology. Datto has developed proprietary synchronization technology across a wide range of use cases to allow SMB PCs and devices to efficiently and securely send data to the Datto Cloud without saturating local internet connections. This includes multi-pass synchronization technology that enables local workloads to continue to operate while a backup is taken and transmitted. It also includes file synchronization software, as well as differential assessment, transmission and verification capabilities to enable an MSP to control the transmission and verification of large data sets to the Datto Cloud.

•RMM integrated cloud-managed networking devices. By combining the network cloud API with RMM management dashboards, the Datto RMM engine is able to provide access to network configuration and runtime data that greatly exceeds off-the-shelf solutions reliant on SNMP for device connectivity. This cloud-level integration provides much greater control of Datto Networking devices than can be achieved by combining products from different networking and remote monitoring and management vendors. As a result, MSP technicians solving SMB customer tickets experience a seamless environment, increasing productivity and responsiveness.

•Proprietary embedded RMM Ransomware Detection. One of the largest security threats for MSPs and their SMB customers is ransomware, and Datto RMM now incorporates the first embedded ransomware detection algorithm into deployed RMM agents. On all Datto RMM managed devices, the agent now observes the local system for signs of crypto ransomware. When identified, the agent attempts to stop the encryption process and automatically isolates the system from the network, alerting the MSP to the infection. This allows MSPs to prevent the spread of ransomware, and proactively restore infected systems.

•Hyper-converged hybrid cloud connected edge device. Datto is differentiated in that it deploys a true hyper-converged continuity appliance that combines data storage with local compute capabilities. Alternative continuity systems generally only provide gateway functionality with virtualization occurring either exclusively in the cloud or on other equipment furnished by end-customers on-premises. Datto allows very flexible orchestration of VM instances in either the cloud or on the edge device.

Our Partners

Datto creates technology for MSPs, enabling them to deliver managed services to their SMB customers and also enabling MSPs to efficiently operate their own businesses. MSPs represent substantially all of our revenue and are referred to as our “partners.” Our MSP partners purchase our products on a subscription basis for inclusion in managed services sold to their end-customers in a recurring revenue model or for their own use. Our MSP partners range in size from very small to mid-sized, and primarily serve SMBs, often managing an SMB customer’s entire IT environment. In smaller MSPs, the business owner or CEO is typically the purchaser of Datto products, and in larger MSPs, the purchaser is often the Vice President of Product or Chief Technology Officer.

Our Unified Continuity, Networking and Endpoint Management products are purchased by MSPs for resale to their SMB customers as part of their managed services offerings, with subscription fees based on workloads or applications protected through our BCDR products, the number of Microsoft 365 or Google Workspace employee accounts at the SMB domains that our MSP partners protect through our SaaS Protection+ products, or the number of endpoints managed and protected through our RMM platform. Generally, an MSP first purchases a subscription to assess our products and evaluate whether to include them in their managed service offering. Following a successful initial assessment, the MSP typically adds to their subscriptions to cover additional workloads, applications, seats and endpoints for its customers over time. Our Business Management products are purchased by an MSP for their own use, with subscription fees based on their number of seats.

As of December 31, 2021, we partnered with more than 18,500 MSPs serving over 1.5 million SMBs. We count partners as MSPs with active subscriptions for one or more of our products at the end of the measured period. Our revenue is highly diversified across our entire partner base, with no single partner making up more than 0.5% of our ARR. As of December 31, 2021, we had over 1,400 MSP partners that each contributed more than $100,000 of ARR.

Examples of use cases of MSP partners leveraging our solutions to deliver value to their SMB customers include:

•utilizing our BCDR solutions to help an SMB roll back its IT environment after a phishing e-mail and ransomware has compromised that SMB’s systems;

•upon a server failure, helping an SMB to switch over to our local device until that SMB’s environment has been restored;

•enabling an SMB to operate its environment in our cloud in the event of a natural disaster, such as a hurricane or earthquake;

•after an end-customer accidentally misplaces a laptop, helping the customer restore the lost environment onto new hardware;

•recovering data and files from our cloud when a customer accidentally deletes a file from Microsoft 365 or Google Workspace;

•utilizing Datto Networking solutions to provide production, point of sale, network connectivity and guest Wi-Fi services for a conference or event; and

•using the Datto partner portal to remotely diagnose and fix an SMB’s laptop issues.

Competition

We operate in a dynamic industry driven by the technology needs of SMBs and MSPs. Our competition is generally comprised of MSP-focused vendors, enterprise IT vendors and emerging innovators with niche point solutions. These competitors include:

•Continuity vendors that provide image-based backup solutions with on-premise only, cloud-only or hybrid infrastructure. The level of continuity provided by image-based backup vendors varies widely, from simple image copy to complex image orchestration, copy, failover and failback. Many vendors providing continuity solutions are not exclusively focused on serving MSPs and require customers to procure their own cloud.

•Networking vendors that sell a mix of edge routers, WiFi access points and switches to small, medium and large businesses. Typically, these vendors deliver either enterprise scale products at a high price point, or commodity products at a low price point. Enterprise scale products are designed for the many unique demands of large-scale enterprises and are complex to configure and manage. Commodity hardware vendors provide performant products with fewer features at a lower price point, often not designed for MSP deployment and management.

•Business management and endpoint management software vendors that focus a significant portion of their business on the MSP market provide vertically integrated service management platforms and tools to MSPs to help them operate more efficiently. Many of these vendors are not solely focused on the MSP market, sell directly to end customers to augment their revenue and operate software platforms that are not cloud native.

Table of Contents

Key competitive factors in our market include:

•reliability, security and performance of solutions that protect workloads — data, applications and configurations — and ensure uptime for SMBs;

•MSP-centric, turnkey product capabilities including reliability, multi-tenant cloud management, ease of deployment and manageability at scale;

•ability to provide recurring revenue and margin for MSPs;

•quality and availability of service and support;

•brand awareness, reputation and influence among MSPs; and

•programs, tools and content that help MSPs grow their businesses.

We believe that we compete favorably on these factors.

Marketing and Sales

Our marketing and sales approach begins with our leading content marketing programs that attract MSPs, nurturing these contacts and then efficiently delivering qualified leads to our sales team to close. Once a new MSP is added to our platform, our sales team works with them to help them grow. Using our go-to-market enablement programs, MSPs add new SMBs, upsell into their existing SMB customers as they add new employees, applications or endpoints, and cross-sell additional Datto products. Post-sales engagement with our service and success teams ensures partners are either effectively using or are enabled to resell our products, and ongoing relationship management at scale allows our partners to sell, upsell and cross-sell more of our products.

Marketing

Our marketing engine delivers industry-leading content, which drives our target audience—MSP business owners and decision makers—to request a demo or become a partner. We distribute our content through a number of digital marketing platforms (social, pay-per-click, search engine optimization, syndication, webinars), and we leverage demos to nurture and further qualify leads. Analytics of this process enable us to fine tune programs and content to drive more successful and qualified lead generation.

We categorize our leads based on propensity to buy using a real-time analytical model. We leverage high touch tactics to attract the higher scoring leads and rely on self-service at the low end. We market Datto as the MSP technology company, creating technology for SMBs delivered by MSPs. Once an MSP becomes a Datto partner, we help it grow with a variety of programs to ensure they are optimally using the products they purchased and are enabled to resell our products through to SMB customers. Our marketing programs also help our partners attract new SMB customers. We leverage our in-depth knowledge and understanding of MSPs to design these free programs, which include a marketing automation tool, robust marketing content, sales training and certifications.

We also foster one of the largest MSP communities in the world through our numerous events. DattoCon and MSP Technology Days are among the largest MSP events in the world. In 2021, our dedicated community development team hosted over 150 Datto virtual and in-person events for our partners and prospects around the globe, educating them on best practices, refreshing them on the latest technology and providing insights they can use to grow their businesses. We also exhibit at third-party in person and virtual tradeshows where we continue to engage with MSPs and expand the Datto brand. We believe that fostering a cohesive MSP community and serving as a trusted thought leader for MSPs around the world helps drive MSP growth, which in turn drives Datto growth. These events, combined with our content and digital marketing strategies, help ensure that our partners stay in touch with our brand, maintaining our lead in the MSP market.

Sales

We believe that leveraging the MSP channel creates high levels of sales productivity at low customer acquisition costs, allowing us to efficiently reach SMBs. We add MSP partners to our platform primarily through our sales team. There are three sales teams pursuing new MSP partners and covering our existing partner base: Sales Development Representatives ("SDRs"), MSP Acquisition Representatives ("Hunters") and MSP Growth Representatives ("Farmers"). SDRs review leads from our marketing team and qualify new partner opportunities, and Hunters are responsible for pursuing and closing these opportunities, leading to a new MSP partner adopting one or more of our products. Farmers work with our partners after their first purchase and build relationships, focusing on increasing the penetration of and upselling existing products, as well as cross-selling additional products. Our sales teams are organized by geography, consisting of the Americas, EMEA and APAC.

Our MSP partners become multipliers to our sales team with our Unified Continuity, Networking and Endpoint Management products. With aligned incentives, our Farmers and our partners’ own sales teams work together at scale using a range of “sell with” tactics along with the enablement and training resources available on our marketing platform to help such partners grow their base of SMB customers purchasing managed services powered by Datto solutions and expand their footprint within those customers.

Services, Success and Support

Services and Success

Our services team onboards MSP partners, helps them properly configure and implement our solutions and trains them to use our products to their fullest potential. Our success team provides cross-functional support for partners to drive increased adoption, product usage and subscription renewals and is responsible for relationship and escalation management.

Support

Our support team includes experienced, trained resources located around the world to provide 24x7x365 technical support for all our products. Support is included in all our offerings as long as an MSP partner’s subscription is active. All support tiers offer maintenance releases, patches and access to our support services and portal, including a documentation and knowledge repository, how-to guides, videos and a community where our partners can ask questions and find answers. Our support is distinguished by our “direct to tech” support model whereby our expert technicians immediately answer support calls and speak directly with partners to resolve issues. This includes “code red” support where we work with an MSP partner during a disaster or other incident to minimize disruption to their customer’s business.

Similar to the sales leverage we gain through the MSP channel, our partners also are a multiplier for our support team because they perform first-level technical support with SMBs, only calling Datto when they are unable to resolve an issue. In complex situations such as multiple or repeat issues affecting an MSP, our success team may get involved in an escalation. Our executive leaders also regularly speak with partners as part of our commitment to openness and accessibility.

Product Development

Product development and innovation are at the core of our business. We not only invent technology, but we also reinvent it for MSPs. Our research and development teams are composed of product management, software development and infrastructure engineering functions. These groups are responsible for the design, development, testing and delivery of our solutions. We build our products from inception to serve the needs of MSPs and their SMB customers and continually seek to improve those products.

We have designed our development processes to be highly responsive and cost-efficient. Our diversified global footprint allows us to source from a large pool of talented resources by participating in multiple labor markets. We utilize an Agile development process and small Scrum teams, each dedicated to specific product modules that follow a standard set of best practices and a common set of development values.

Intellectual Property

We rely on a combination of patent, copyright, trademark and trade secret laws in the United States and other jurisdictions, as well as confidentiality and other contractual restrictions to protect our proprietary rights, including our proprietary technology, software, know-how and brands. As of December 31, 2021, we owned 35 issued U.S. patents, with expiration dates ranging from September 2025 to September 2040. We have also filed 15 patent applications in the United States which are pending, and four patent applications with the Patent Cooperation Treaty (PCT). We cannot be assured that any of our patent applications will result in the issuance of a patent or whether the examination process will require us to narrow the scope of the claims sought. We do not believe that we are materially dependent on any one of our patents, issued or pending.

We require our employees, consultants and other third parties to enter into confidentiality and proprietary rights agreements and we control and monitor access to our software, proprietary technology and documents and other confidential information. Our policy is to require all employees and independent contractors to sign agreements assigning to us any inventions, trade secrets, developments, processes and other intellectual property generated by them on our behalf and under which they agree to protect our confidential information.

Although we rely on intellectual property rights as well as contractual protections to establish and protect our proprietary rights, we believe that factors such as the technological and creative skills of our personnel, creation of new services, features and functionality and frequent enhancements to our platform are more essential to establishing and maintaining our technology leadership position.

Human Capital

Datto’s mission to create enterprise-grade technology for SMBs delivered through MSP partners begins with its commitment to Datto employees. We think that the innovation Datto provides to the MSP community is inextricably linked to our talented, world-class global workforce, and that our ability to recruit, retain and develop highly skilled talent is critical to our future success and growth. As of

Table of Contents

December 31, 2021, we had 2,089 employees, of which 1,569 (75%) were employed in the United States and 520 (25%) were employed outside of the United States. We are not party to any collective bargaining agreements.

Compensation & Benefits

Our rewards programs are designed to attract, reward, and retain our talented employees globally. We offer programs that are highly competitive, locally relevant and provide the resources needed to live a full and balanced life. Our compensation packages include base salary, opportunities for equity ownership, and commission or bonuses for selected roles. In addition, we offer an employee stock purchase plan, through which eligible employees may choose to buy Datto common stock at a discount twice a year.

Our benefits include comprehensive healthcare, income protection insurance, time off and leave programs, retirement programs and additional resources to support employees' overall well-being. Our health benefits include medical plans including telemedicine, dental plans, vision, flexible spending accounts, and health savings accounts. Our employees participate in flexible vacation policies, paid time off, and paid parental and family leave. We support our employees’ financial health with a 401(k) plan with company matching contributions, disability and life insurance. Employee well-being is further supported with access to an employee assistance program, subscriptions to well-being apps, virtual yoga and a robust recognition program.

We evaluate our compensation and benefit offerings on an annual basis to ensure competitiveness and we adjust our programs as needed. We believe these programs deliver compensation and benefits that are competitive with other companies with whom we compete for talent.

Diversity, Equity & Inclusion

At Datto, we are a global team. We strive to be a diverse and equitable workplace, where everyone is valued, included, and has equal access to growth and development opportunities to maximize their full potential. We value diverse perspectives and foster a culture of transparency and trust. We will listen to all voices and model inclusive behavior as essential to our core values. We will invest in and empower our employees and partners as they deliver mission critical technology to small and medium businesses.

We strive to maintain an inclusive environment free from discrimination of any kind. We believe that fostering this environment builds a foundation on which our employees are empowered to do their life's work. Our employee resource groups ("ERGs") are company-sponsored groups of employees that promote and support certain objectives including inclusion and diversity, career development and networking. As of December 31, 2021, we sponsored four ERGs: Datto Women in Technology, Datto Pride, Datto Culture, and Datto Familia.

We require unconscious bias training across our entire organization. In addition, we support the development of our leadership team by embedding trainings on leading inclusively in all levels of our management and leadership development programs. We aim to ensure our employees are aware of different ways to notify management of inappropriate behavior, including through a confidential hotline. Any and all reports of inappropriate behavior are taken very seriously and thoroughly investigated and remediated.

Employee Learning & Development

We offer high-quality learning experiences across our global business. This includes an extensive onboarding program, robust sales, product and technical training, as well as a comprehensive professional skills curriculum focused on managerial and leadership skills. We also launched an internal networking and mentoring program intended to connect employees across Datto to foster relationships, development and the exchange professional and personal experiences, skills, and career paths.

Risks Related to the COVID-19 Pandemic

The ultimate impact of the ongoing COVID-19 pandemic remains highly uncertain.

While we have not yet incurred significant disruptions from the COVID-19 pandemic, COVID-19 continues to spread throughout the United States and globally, and the duration, magnitude and severity of its effects and ultimate impact on our business and financial condition remain uncertain. Efforts to combat the COVID-19 virus have been complicated by viral variants and uneven access to, and acceptance and effectiveness of, vaccines globally. While travel bans and restrictions, shelter-in-place orders, shutdowns, and other government orders and restrictions have been eased since the inception of the pandemic, uncertainty continues to exist regarding such measures and potential future measures. Current restrictions and orders may continue and future measures may be enacted, all of which could result in business disruptions and closures, slowdowns and delays, supply chain disruptions, work-from-home policies, and cancellation or postponement of events, among other effects, which could adversely impact our operations, including affecting the behavior and operations of our MSP partners, their SMB customers and our suppliers.

In response to these government actions and mandates, we have modified and may continue to modify our business practices, including, among others, permitting almost all employees to work from home, substantially curtailing employee travel, cancelling or shifting events and conferences to virtual-only, increasing inventories of key device and cloud infrastructure components, and working with our network of suppliers to ensure future orders can be fulfilled. Our results of operations, financial condition and ability to operate normally could be harmed as a result of these changed business practices.

Additionally, the COVID-19 pandemic has caused a global recession and the sustainability of the economic recovery observed in 2021 remains unclear. The COVID-19 pandemic, as well as measures taken to contain the spread of COVID-19, could decrease the spending of our existing and potential new MSP partners or their SMB customers; cause our MSP partners to fail to renew, reduce, shorten, terminate, or renegotiate their subscriptions for our services; and lengthen collection periods of accounts receivable. Some of our MSP partners or their SMB customers have experienced and may continue to experience financial hardships which could result in delayed or uncollectible payments. In particular, SMBs may be more susceptible to the adverse effects of economic fluctuations, including as a result of the COVID-19 pandemic. Any of these developments could adversely affect our business, results of operations, and financial condition. Additionally, concerns over the economic impact of the COVID-19 pandemic have caused extreme volatility in financial and other capital markets which may adversely impact our stock price.

The inability to meet in person with potential MSP partners or customers, to participate in in-person conferences and other industry events that lead to sales generation could lead to decreased effectiveness of our employees which could result in reduced sales, longer time periods to deploy software and support our products, or other decreases in productivity that could adversely affect our results, . We may experience difficulties in recruiting, engaging or retaining personnel because of our more highly dispersed workforce. In addition, as a result of financial or operational difficulties, our suppliers may experience delays or interruptions in their ability to provide services to us, if they are able to do so at all. Any disruptions to services provided to us by third parties that we rely upon to provide our solutions, including as a result of actions outside of our control, could significantly impact our continued performance. The COVID-19 pandemic may also heighten other risks described below.

Risks Related to Our Brand and Industry

We face intense competition in our market, especially from larger, well-established companies and vendors with an MSP focus, and we may not be able to maintain or improve our competitive position.

We operate in an intensely competitive and dynamic industry driven by the technology needs of SMBs and MSPs. We expect competition to increase in the future from established competitors and new market entrants. SMBs are increasingly turning to MSPs, to service their technology needs because of increasing complexity and enhanced regulatory and security risks. MSPs, as a result, are constantly looking for the next service offering for their customers. Our competition is generally comprised of enterprise IT vendors and emerging innovators with niche point solutions, which include:

•Endpoint management and business management software vendors that focus a significant portion of their business on the MSP market, providing vertically integrated service management platforms and tools to MSPs to help them operate more efficiently. Many of these vendors are not solely focused on the MSP market, sell directly to end customers to augment their

Table of Contents

revenue and operate software platforms that are not cloud native. ConnectWise, Kaseya and N-Able are examples of such vendors.

Many of our existing competitors have, and some of our potential competitors could have, substantial competitive advantages such as:

•greater name recognition and longer operating histories;

•broader distribution and established relationships with MSPs;

•larger sales and marketing budgets and resources;

•greater customer support resources;

•greater resources to make strategic acquisitions or enter into strategic partnerships;

•lower labor and development costs;

•larger and more mature intellectual property portfolios; and

•substantially greater financial, technical and other resources.

In addition, some of our larger competitors have substantially broader and more diverse product and services offerings, which may make them less susceptible to downturns in a particular market and allow them to leverage their relationships based on other products or incorporate functionality into existing products to grow their business in a manner that discourages users from purchasing our products and subscriptions, including through selling at zero or negative margins, offering concessions, product bundling or closed technology platforms. Many of our smaller competitors that specialize in one particular offering designed specifically for MSPs, such as network assessment utilities, documentation tools, management dashboards, monitoring agents, security solutions or cloud migration capabilities, are often able to deliver these specialized products to the market more quickly and cheaply than we can.

MSPs or SMBs that use legacy products and services of our competitors may believe that these products and services are sufficient to meet their IT needs or that our platform only serves the needs of a portion of the SMB IT market. Accordingly, these organizations may continue allocating their IT budgets for such legacy products and services and may not adopt our Unified Continuity, Networking, Endpoint Management and Business Management software, solutions and hardware. Further, many organizations have invested substantial personnel and financial resources to design and operate their networks and have established deep relationships with other providers of the products we offer. As a result, these organizations may prefer to purchase from their existing suppliers rather than to add or switch to a new supplier using our products and services, regardless of product performance, features or greater service offerings, or may be more willing to incrementally add solutions to their existing IT infrastructure from existing suppliers than to replace it wholesale with our solutions.

Conditions in our market could change rapidly and significantly as a result of technological advancements, partnering or acquisitions by our competitors, or continuing market consolidation. New start-up companies that innovate and large competitors that make significant investments in research and development may invent similar or superior products and technologies that compete with our products and subscriptions. Some of our competitors have made or could make acquisitions of businesses that may allow them to offer more directly competitive and comprehensive products than they had previously offered and adapt more quickly to new technologies and MSP or SMB needs. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources and better compete with our MSP partner network.

These competitive pressures in our market or our failure to compete effectively may result in price reductions, fewer orders, reduced revenue and gross margins and loss of market share. Any failure to meet and address these factors could seriously harm our business and operating results.

We depend on growth in the SMB IT market, and lack of growth or contraction in this market could have a material adverse effect on our sales and financial condition.

Demand for SMB IT is linked to growth in the amount of data generated and stored, demand for data retention and management (whether as a result of regulatory requirements or otherwise) and demand for and adoption of new storage devices and networking technologies. Because our software, solutions and hardware are concentrated within SMB IT, if the demand for unified continuity, networking, endpoint management or business management solutions declines or develops more slowly than we expect, our sales, results of operations and financial condition would be materially adversely affected. Segments of the IT services industry have in the past experienced significant economic downturns. The occurrence of any of these factors in the data and information management software market could materially adversely affect our sales, results of operations and financial condition.

Table of Contents

Furthermore, the SMB IT market is dynamic and evolving. Our future financial performance will depend in large part on continued growth in the number of SMBs adopting IT management software for their computing environments through our MSP partners. The SMB IT market may not continue to grow at historic rates, or at all. If this market fails to grow or grows more slowly than we currently anticipate, our sales and results of operations could be adversely affected.

If we do not accurately predict, prepare for and respond promptly to rapidly evolving technological and market developments to meet changing end-user needs in the SMB IT market and the corresponding needs of MSPs, our competitive position and prospects will be harmed.

The SMB IT market has grown quickly and is expected to continue to evolve rapidly. Moreover, many of our users operate in markets characterized by rapidly changing technologies and business plans, which require them to adopt increasingly complex networks, incorporating a variety of hardware, software applications, operating systems and networking protocols. Our long-term growth depends on our ability to continually enhance and improve our existing products and develop or acquire new products that address the common problems encountered by technology professionals on a daily basis in an evolving IT services market. If we fail to accurately predict the changing needs of SMBs or MSPs and emerging technological trends in the SMB IT market, including in the areas of unified continuity, networking, endpoint management and business management, our business and operating results could be harmed. In particular, our continuity solutions represent a significant source of our revenue and any decrease in demand for these solutions resulting from our competitors’ technologies or changing SMB needs would adversely impact our revenue and operating results.

The technology in our software solutions and hardware is especially complex because it needs to effectively enable MSPs to address and solve critical workflow and operational challenges of SMBs and to do so remotely and quickly with multiple SMB customers. Additionally, some of our new products’ features and related enhancements may require us to develop new hardware architectures that involve complex, expensive and time-consuming research and development processes. The development of our software, solutions and hardware is difficult and the timetable for commercial release and availability is uncertain as there can be long time periods between releases and availability of new features. If we experience unanticipated delays in the availability of new products, features and subscriptions, and fail to meet partner expectations for such availability, our competitive position and business prospects will be harmed.

Additionally, we must commit significant resources to developing new features before knowing whether our investments will result in products, subscriptions and features the market will accept. The development and introduction of new solutions involves a significant commitment of time and resources and are subject to a number of risks and challenges including but not limited to lengthy development cycles, evolving industry standards and technological developments by our competitors and partners, evolving platforms, operating systems and hardware products, related product and service interoperability challenges, entering into new or unproven markets, trade compliance difficulties and obtaining sufficient licenses to technology and technical access to operating system software. The success of new features depends on several factors, including appropriate new product definition, differentiation of new products, subscriptions and features from those of our competitors, and market acceptance of these products, subscriptions and features. Moreover, successful new product introduction and transition depends on a number of factors including our ability to manage the risks associated with new product production ramp-up issues, the availability of application software for new products, the effective management of purchase commitments and inventory, the availability of products in appropriate quantities and costs to meet anticipated demand and the risk that new products may have quality or other defects or deficiencies, especially in the early stages of introduction.

There can be no assurance that we will successfully identify opportunities for new products and subscriptions, develop and bring new products and subscriptions to market in a timely manner or achieve market acceptance of our products and subscriptions, or that products, subscriptions and features developed by others will not render our products, subscriptions, features or technologies obsolete or noncompetitive. The increasing prevalence of cloud and SaaS delivery models offered by us and our competitors may unfavorably impact pricing for both our on-premise and cloud-based offerings, as well as overall demand for our on-premise software and service offerings, which could reduce our revenues and harm our results of operations. Specifically, our Unified Continuity business line may be adversely affected by technological advances that allow similar services to be effectively provided through the public cloud, which could drastically reduce the demand for on-premise backup solutions. Currently, our on-premise offerings provide backup recovery services and response times that greatly exceed the offerings that can be provided by solely cloud-based providers. We are able to provide these superior services in part because of to the physical on-premise location of the devices that enable many of our business continuity and disaster recovery, or BCDR, solutions. Currently, the cloud technology cannot compete with our BCDR services because of transmission constraints and cost factors, as well as lack of control over data in the public cloud. However, if competitors were to develop affordable public cloud-based technologies that could provide similar BCDR response times and services, these competitors could replace the need for our hybrid on-premise offerings and solutions. If this public cloud-based technology were to develop and be offered to the market and we did not adequately adapt our own offerings, we would face the risk of MSPs and SMBs choosing our competitors’ cloud-based offerings in lieu of our offerings.

Risks Related to our Business

Our operating results may vary significantly from period to period and be unpredictable, which could cause the market price of our common stock to decline.

While our operating results, in particular, our revenues, have historically been recurring and predictable from period to period, variation may occur as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:

•our ability to attract and retain new MSP partners or sell additional products and subscriptions to our existing MSP partners for internal use or resale to their SMB customers;

•our ability to expand our sales and marketing operations in order to achieve broader market penetration;

•a decline in subscription renewals;

•the budgeting cycles, seasonal buying patterns and purchasing practices of our MSP partners and their SMB customers;

•changes in MSPs’ and SMBs’ requirements or market needs;

•our ability to obtain, maintain, protect and enforce our intellectual property rights;

•price competition;

•the timing and success of new product and service introductions by us or our competitors or any other change in the competitive landscape of our industry, including consolidation among our competitors, MSP partners or SMBs and strategic partnerships entered into by and between our competitors;

•changes in the mix of our products and subscriptions, including changes in multi-year subscriptions;

•our ability to successfully and continuously expand our business domestically and internationally;

•changes in the growth rate of the enterprise-grade technology services market for SMBs;

•timing and amount of our investments to expand the capacity in our data center facilities;

•deferral of orders from MSP partners in anticipation of new products or product enhancements announced by us or our competitors;

•the timing, costs and effects related to the development or acquisition of technologies, businesses or strategic partnerships and their integration;

•decisions by potential SMBs to purchase software and technology from MSP partners other than those that offer our products and services;

•changes in SMB market penetration through MSP partners or renewal rates for our subscriptions;

•timing of revenue recognition and revenue deferrals;

•our ability to manage production and manufacturing related costs, global customer service organization costs, inventory excess and obsolescence costs and warranty costs;

•insolvency or credit difficulties confronting our MSP partners or their SMB customers, which could adversely affect our partners’ ability to purchase or pay for our products and subscription and support offerings;

•our inability to fulfill our MSP partners’ orders because of supply chain delays or events that impact our manufacturers or their suppliers;

•changes in regulatory or legal environments that may cause us to incur, among other elements, expenses associated with compliance;

•significant security breaches of, technical difficulties with, or interruptions to, the delivery and use of our products;

•future accounting pronouncements or changes in our accounting policies;

•future changes in tax rates or tax reforms in jurisdictions in which we operate;

Table of Contents

•increases or decreases in our revenue and expenses caused by fluctuations in foreign currency exchange rates, as an increasing amount of our revenue and expenses is generated and incurred and paid in currencies other than the U.S. Dollar;

•increases or decreases in our expenses caused by fluctuations in tariffs between the United States and countries in which we have supplier relationships;

•political, economic and social instability, including, for example, uncertainty caused by the United Kingdom's exit from the European Union commonly referred to as “Brexit,” and continued hostilities in the Ukraine and the Middle East, terrorist activities and any disruption these events may cause to the broader global industrial economy; and

•general macroeconomic conditions, both domestically and in our foreign markets that could impact some or all regions where we operate, including the global economic effect of COVID-19.

Any one of the factors above, or the cumulative effect of some of the factors referred to above, may result in significant fluctuations in our financial and other operating results. This variability and unpredictability could result in our failure to meet our revenue, margin or other operating result expectations or those of securities analysts or investors for a particular period. If we fail to meet or exceed such expectations for these or any other reasons, the market price of our common stock could fall substantially, and we could face costly lawsuits, including securities class action suits.

The ability to recruit, retain and develop key employees and management personnel is critical to our success and growth, and our inability to attract and retain qualified personnel could harm our business.

Our business requires certain expertise and intellectual capital, particularly within our management team. We rely on our management team in the areas of operations, research and development, information security, marketing, sales, support and general and administrative functions. We are also dependent on the continued service of our existing software engineers because of the complexity of our products. Our management team and other key personnel could terminate their employment with us at any time. The loss of one or more of our management team could have a material adverse effect on our business.

For us to compete successfully and grow, we must retain, recruit and develop key personnel who can provide the needed expertise for our industry, MSP partners and products, particularly with respect to engineering and sales. As we move into new geographic areas, we will need to attract, recruit and retain qualified personnel in those locations. In addition, acquisitions could cause us to lose key personnel of the acquired businesses. The market for qualified personnel is competitive and we may not succeed in recruiting additional key personnel or may fail to effectively replace current key personnel who depart with qualified or effective successors. We believe that replacing our key personnel with qualified successors is particularly challenging as we feel that our business model and approach to marketing and selling our products are different than those of our competitors. Any successors that we hire from outside of the Company, in particular, sales representatives, would likely be unfamiliar with our business model and may therefore require significant time to understand and appreciate the important aspects of our business or fail to do so altogether. Our effort to retain and develop personnel may also result in significant additional expenses, including stock-based compensation expenses, which could adversely affect our results of operations. New regulations and volatility or lack of performance in our stock price could also affect the value of our equity awards, which could affect our ability to attract and retain our key employees. We have made significant changes, and may make additional changes in the future, to our management team and other key personnel. We cannot provide assurances that key personnel will continue to be employed by us or that we will be able to attract and retain qualified personnel in the future. Failure to retain or attract key personnel could have a material adverse effect on our business.

We may not be able to achieve or sustain the same level of cash flows in the future.

We expect our operating expenses may increase over the next several years as we hire additional personnel, expand our operations and infrastructure, both domestically and internationally, pursue business combinations and continue to develop our software, hardware and services. As a public company, we may incur additional legal, accounting and other expenses that we did not incur historically. If our revenue does not increase to offset these increases in our operating expenses, we will not be able to achieve or maintain profitability in future periods. While historically our total revenue has grown, not all components of our total revenue have grown consistently. Further, in future periods, our revenue growth could slow or our revenue could decline for a number of reasons, including slowing demand for our software, hardware or services, increasing competition, any failure to gain or retain or increase sales to MSP partners, a decrease in the growth of our overall market, our technology or services becoming obsolete because of technical advancements in the SMB IT market or our failure, for any reason, to continue to capitalize on growth opportunities. As a result, our past financial performance should not be considered indicative of our future performance. Any failure by us to achieve or sustain cash flows on a consistent basis could cause us to halt our expansion, not pursue strategic business combinations, default on payments due on existing contracts, fail to continue developing our software, hardware and services or result in other negative changes in our business.

If we are unable to attract new MSP partners, our future results of operations could be harmed.

To increase our revenue and achieve and maintain profitability, one important component is our ability to add new MSP partners to purchase our products both for their own use and for resale to their SMB customers. To do so, we must successfully convince MSP partners that, as they adopt and look to resell our software and technology, including Unified Continuity, Networking, Endpoint Management and Business Management products, our products provide significant advantages over legacy software and technology and are more marketable to SMBs. In addition, numerous other factors, many of which are out of our control, may now or in the future impact our ability to add new MSP partners, including potential MSP partners’ commitments to legacy software and technology providers and products, MSP preference for working with other providers of similar products, MSP partners’ and SMBs’ real or perceived switching costs, our failure to recruit, train, retain and motivate sufficient numbers of sales and marketing personnel, our failure to develop or expand relationships with our MSP partners or to attract new MSP partners, failure by us to help our MSP partners successfully deploy, troubleshoot and manage our solutions for their own use or on behalf of SMB customers, negative media or industry or financial analyst commentary regarding us or our solutions, litigation and deteriorating general economic conditions. If our efforts to attract new MSP partners are not successful, our revenue and rate of revenue growth may decline, we may not achieve profitability and our future results of operations could be materially harmed.

If we are unable to sell additional products and subscriptions to our MSP partners or they are unable to resell additional offerings to their SMB customers, our future revenue and operating results will be harmed.

Our future success depends, in part, on our ability to expand the deployment of our software and solutions with existing MSP partners, which are both the customers of our Business Management solutions and our primary channel for effectively reaching their SMB customers with our Unified Continuity, Networking and Endpoint Management solutions. Currently, all of our products are sold on a recurring subscription basis and we rely on SMB demand to drive MSP purchases of our Unified Continuity, Networking and Endpoint Management solutions. Therefore, our success may require increasingly sophisticated and costly sales efforts to collaborate with MSP partners that may not result in additional sales. The rate at which our MSP partners purchase additional products and subscriptions depends on a number of factors, including the perceived need of SMBs for additional or alternative software and technology, including our offerings, as well as general economic conditions.

We rely on revenue from subscription offerings, and because we recognize revenue from subscription over the term of the relevant service period, downturns or upturns in sales of these subscription offerings are not immediately reflected in full in our operating results.

All of our products are sold on a recurring subscription basis, with recurring revenue representing approximately 93% of total revenue for the year-ended December 31, 2021. Sales of new or renewal subscription contracts may decline and fluctuate as a result of a number of factors, including MSP partners’ and SMBs’ level of satisfaction with our products, subscriptions and customer support, the prices of our products and subscriptions, the prices of products and services offered by our competitors and reductions in our MSP partners’ and the SMBs’ spending levels. Accordingly, we must invest significant time and resources in providing ongoing value to our MSP partners and thereby indirectly to their SMB customers. If our sales of new or renewal subscription contracts decline, our total revenue and revenue growth rate may decline and our business will suffer. In addition, we recognize subscription revenue monthly over the term of the relevant service period, which is typically one to three years or monthly. As a result, a portion of the subscription revenue we report each fiscal quarter is the recognition of deferred revenue from subscription contracts entered into during previous fiscal quarters.

Further, existing MSP partners may opt not to renew their subscriptions after the completion of their initial contract period. Our MSP partners have no obligation to renew their subscriptions for our products after the expiration of their subscription period. Our MSP partners’ renewal rates may decline or fluctuate as a result of a number of factors, including their level of satisfaction and their SMB customers’ level of satisfaction with our subscriptions and our support offerings, the frequency and severity of subscription outages, our product uptime or latency and the pricing of our, or competing, subscriptions. Additionally, some MSP partners may renew their subscriptions for month-to-month terms or on other terms that are less economically beneficial to us. If our efforts to sell additional products and subscriptions to and through the MSP partners are not successful or our MSP partners do not renew their subscriptions or renew them on less favorable terms, our revenues may grow more slowly than expected or decline.

Consequently, a decline in new or renewed subscription contracts in any one fiscal quarter may not be fully or immediately reflected in revenue in that fiscal quarter and could negatively affect our revenue in future fiscal quarters. Also, it is difficult for us to rapidly increase our subscription revenue through additional subscription sales in any period, as revenue from new and renewal subscription contracts must be recognized over the applicable service period.

We have experienced substantial growth in recent years, and if we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of MSP partner satisfaction or adequately address competitive challenges, and our financial performance may be adversely affected.

Table of Contents

Our business has rapidly grown, which has resulted in large increases in our number of employees, expansion of our infrastructure, new internal systems and other significant changes and additional complexities. We increased our total number of employees to 2,089 as of December 31, 2021, from 1,743 at December 31, 2020. While we intend to further expand our overall business, partner base and number of employees, our historical growth rate is not necessarily indicative of the growth that we may achieve in the future. The growth in our business generally and our management of a growing workforce and MSP partner base geographically dispersed across the United States and internationally will require substantial management effort, infrastructure and operational capabilities. To support our growth, we must continue to improve our management resources and our operational and financial controls and systems, and these improvements may increase our expenses more than anticipated and result in a more complex business. We will also have to anticipate the necessary expansion of our relationship management, implementation, customer service and other personnel to support our growth and achieve high levels of customer service and satisfaction. Our success will depend on our ability to plan for and manage this growth effectively. If we fail to anticipate and manage our growth or are unable to provide high levels of customer service, our reputation, as well as our business, results of operations and financial condition, could be harmed.

Because our long-term success depends on our ability to operate our business internationally and increase sales of our products to MSP partners located outside of the United States, our business is susceptible to risks associated with international operations.

We have international operations in Australia, Canada, China, Denmark, Germany, Israel, the Netherlands, Singapore and the United Kingdom. We also expect to continue to expand our international operations for the foreseeable future. The continued international expansion of our operations requires significant management attention and financial resources and results in increased administrative and compliance costs. Although we continue to develop strategies to address international markets, our limited experience in operating our business in certain regions outside the United States increases the risk that our expansion efforts into those regions may not be successful. These risks include, but are not limited to:

•fluctuations in currency exchange rates;

•the complexity of, or changes in, foreign regulatory requirements, including more stringent regulations relating to privacy and data security and the unauthorized use of, or access to, commercial and personal information, particularly in Europe;

•difficulties in managing the staffing of international operations, including compliance with local labor and employment laws and regulations;

•potentially adverse tax consequences, including the complexities of foreign value added tax systems, overlapping tax regimes, restrictions on the repatriation of earnings and changes in tax rates, including the impact of Brexit;

•dependence on MSP partners to increase customer acquisition or drive localization efforts;

•the burdens of complying with a wide variety of foreign laws and different legal standards;

•the need to adapt and localize our products for specific countries;

•increased financial accounting and reporting burdens and complexities;

•longer payment cycles and difficulties in collecting accounts receivable;

•longer sales cycles;

•political, social and economic instability abroad;

•terrorist attacks and security concerns in general;

•reduced or varied protection for intellectual property rights in some countries; and

•the risk of U.S. regulation of foreign operations.

The occurrence of any one of these risks or other risks that we may not be able to anticipate could negatively affect our international business and, consequently, our operating results. We cannot be certain that the investment and additional resources required to establish, acquire or integrate operations in other countries will produce desired levels of revenue or profitability. If we are unable to effectively manage our expansion into additional geographic markets, our financial condition and results of operations could be harmed.

In particular, we operate a portion of our research and development activities internationally and outsource a portion of the coding and testing of our products and product enhancements to contract development vendors. These activities take place in a variety of locations, including China, the United Kingdom, Germany and Denmark. We believe that performing research and development in our international facilities and supplementing these activities with our contract development vendors enhances the efficiency and cost-

Table of Contents

effectiveness of our product development. If we experience problems with our workforce or facilities internationally, we may not be able to develop new products or enhance existing products in a cost-efficient and effective alternate manner.

Volatility in the global economy could adversely impact our continued growth, results of operations and our ability to forecast future business.

As our business has expanded globally, we have become increasingly subject to the risks arising from adverse changes in domestic and global economic and political conditions. Uncertainty in the macroeconomic environment and associated global economic conditions have resulted in volatility in credit, equity, debt and foreign currency markets as well as government budgets worldwide.

These global economic conditions can result in slower economic activity, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions and liquidity concerns. There has also been increased volatility in foreign exchange markets. These factors make it difficult for us, our MSP partners and our vendors to accurately forecast and plan future business activities. In addition, these factors could cause our MSP partners to slow or defer spending on our solutions, which would delay and lengthen sales cycles and negatively affect our results of operations. If such conditions deteriorate or if the pace of economic recovery is slower or more uneven, our results of operations could be adversely affected, we may not be able to sustain the growth rates we have experienced recently, and we could fail to meet the expectations of stock analysts and investors, which could cause the price of our common stock to decline.

We continue to invest in our business in the European and Asia-Pacific regions. There are significant risks with overseas investments and growth prospects in these regions. Increased volatility or declines in the credit, equity, debt and foreign currency markets in these regions could cause delays in or cancellations of orders. Deterioration of economic conditions in the countries in which we do business could also cause slower or impaired collections on accounts receivable. In addition, we could experience delays in the payment obligations of our MSP partners if they experience weakness in the SMB market, which would increase our credit risk exposure and harm our financial condition.

Most of our revenue is generated by sales through our MSP partners, and if these MSP partners fail to perform, our ability to sell and distribute our products and subscriptions will be very limited, and our operating results will be harmed.

Most of our revenue is generated by sales through our MSP partners. We provide our MSP partners with training materials and programs to assist them in selling our products and subscriptions, but there can be no assurance that these steps will be utilized or effective. Even following an effective onboarding of an MSP partner that understands our products and how to manage them on behalf of their SMB customers, it may take several months or more for a new MSP partner to achieve productivity. In addition, our MSP partners may be unsuccessful in marketing, selling and supporting our products and subscriptions and can cease marketing or reselling our solutions at any time with limited or no notice. We may not be able to incentivize these MSP partners to sell our products and subscriptions to SMBs. A substantial number of our agreements with our MSP partners are non-exclusive such that those MSP partners may offer customers the solutions of several different companies, including solutions that compete with ours. These MSP partners may also have incentives to promote our competitors’ products and may devote more resources to the marketing, sales and support of competitive products. Our agreements with our MSP partners may generally be terminated for any reason by either party upon the expiration of the applicable annual or monthly subscription period, subject to compliance with the notice requirements set forth in the applicable agreement.

We cannot be certain that we will retain these MSP partners or that we will be able to secure additional or replacement MSP partners. We also cannot be certain that our MSP partners will retain their SMB customers to which they resell our products. Our MSP partner sales structure could subject us to lawsuits, potential liability and reputational harm if, for example, any of our MSP partners misrepresent the functionality of our products, improperly market our products or subscriptions to SMB customers or violate laws or our corporate policies. Because our MSP partners market our products without our direct oversight, any misrepresentation or inappropriate marketing of our products or solutions by our MSP partners may cause SMB customers to be disappointed in our products or cause end-users to seek redress or assistance from us directly. If we fail to effectively manage our sales channels or MSP partners, our ability to sell our products and subscriptions and operating results will be harmed.

Our business could be materially and adversely affected as a result of natural disasters, terrorism or other catastrophic events.

Datto helps businesses recover in the wake of disaster by providing full image-based backup, virtualization and restore of a SMB’s full environment, as well as software as a service, or SaaS, application backup and restore and network monitoring and management. However, any material disruption caused by natural disasters, including fires, floods, hurricanes, earthquakes and tornadoes, power losses or shortages, environmental disasters, telecommunications or business information systems failures or break-ins and similar events could still adversely affect our ability to conduct business. If such disruptions result in cancellations of orders or contribute to a general decrease in economic activity or corporate spending on IT, or impair our ability to meet our MSP partner demands, our operating results and financial condition could be materially adversely affected. Additionally, if such disruptions were to occur within the Datto data centers and caused us to be unable to provide our continuity services, our business and operations would be materially adversely affected.

We invest in research and development activities in both the short and long term, and these investments may achieve delayed, or lower than expected, benefits which could harm our operating results.

While we continue to focus on managing our costs and expenses, we also continue to invest significantly in research and development activities, in both the short and long term, as we focus on organic growth through internal innovation across each of our product offerings. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts to maintain our competitive position, and that the level of these investments will increase in future periods. We recognize the costs associated with these research and development investments earlier than the anticipated benefits, and the return on these investments may be lower, or may develop more slowly, than we expect. If we do not achieve the benefits anticipated from these investments, or if the achievement of these benefits is delayed, our operating results may be adversely affected.

Because we depend on manufacturing partners to build and ship components of our products, we are susceptible to manufacturing and logistics delays and pricing fluctuations that could prevent us from shipping orders on time, if at all, or on a cost-effective basis, which may result in the loss of sales and loss of our MSP partner relationships. Manufacturing and shipping of supplies could be further delayed because of supply chain shortages from the reopening of economies as a result of COVID-19.

We depend on manufacturing partners as manufacturers for physical components of our product lines. Our reliance on these manufacturing partners for our hardware products and servers built for the Datto Cloud, reduces our control over the manufacturing process and exposes us to risks, including reduced control over quality assurance, product costs, product supply, timing and transportation risk. Our products are manufactured by our manufacturing partners at facilities located in, but not limited to, the United States, China, the Czech Republic, Japan, Taiwan and Thailand. Some of the components in our products are sourced either through a network of distributors or directly by us from component suppliers outside the United States. The portion of our products that are sourced outside the United States may subject us to additional logistical risks or risks associated with complying with local rules and regulations in foreign countries. Significant changes to existing international trade agreements could lead to sourcing or logistics disruption resulting from import delays or the imposition of increased tariffs on our sourcing partners. Each of these factors could severely impair our ability to fulfill orders.

In addition, we are subject to requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, to diligence, disclose and report whether or not our products contain minerals originating from the Democratic Republic of the Congo and adjoining countries, or Conflict Minerals. Although the SEC has provided guidance with respect to a portion of the Conflict Minerals filing requirements that may somewhat reduce our reporting practices, we have incurred and expect to incur additional costs to comply with these disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. These requirements could adversely affect the sourcing, availability and pricing of minerals used in the manufacture of semiconductor devices or other components used in our products. We may also encounter MSPs or SMBs who require that all of the components of our products be certified as conflict free. If we are not able to meet this requirement, such parties may choose not to purchase our products.

Our manufacturing partners typically fulfill our supply requirements on the basis of individual purchase orders. We generally do not have long-term contracts with these manufacturers that guarantee capacity, the continuation of particular pricing terms or the extension of credit limits. Accordingly, they are not obligated to continue to fulfill our supply requirements and the prices we pay for manufacturing services could be increased on short notice. If we are required to change manufacturing partners, our ability to meet our scheduled product deliveries to our end-users could be adversely affected, which could cause the loss of sales to existing or potential end-users, delayed revenue, a strain upon our relationship or termination with the MSP partners who market our products, or an increase in our costs which could adversely affect our gross margins. Any production interruptions for any reason, such as a natural disaster, epidemic, capacity shortages or quality problems, at one of our manufacturing partners would negatively affect sales of our product lines manufactured by that manufacturing partner and adversely affect our business and operating results.

As economies around the world reopened in 2021 following the shutdowns resulting from the COVID-19 pandemic, sharp increases in demand have created significant disruptions in the supply chain, which may affect the Company’s ability to receive goods on a timely basis. These supply chain disruptions have been caused and compounded by many factors, including capacity constraints, labor shortages and shipping container shortages. The Company monitors and attempts to mitigate supply chain risk, but there can be no assurance that our mitigation plans will be effective to prevent disruptions that may arise from shortages of materials that we use in the production of our products. Uncertainties relating to the magnitude and duration of the global supply chain disruptions may adversely affect our business and financial conditions.

Managing the supply of our products and product components is complex. Insufficient supply and inventory may result in lost sales opportunities or delayed revenue, while excess inventory may harm our gross margins.

Our manufacturing partners procure components and build our products based on our purchase orders, and we generally do not hold inventory for a prolonged period of time. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and analyses from our sales and product management organizations, adjusted for overall market conditions. In

Table of Contents

order to reduce manufacturing lead times and plan for adequate component supply, from time to time we may issue purchase orders for components and products that are non-cancelable and non-returnable.

Our inventory management systems and related supply chain visibility tools may be inadequate to enable us to forecast accurately and effectively manage supply of our products and product components. If we ultimately determine that we have excess supply, we may have to reduce our prices and write-down inventory, which in turn could result in lower gross margins. If our actual component usage and product demand are lower than the purchase order we provide to our manufacturing partners, we accrue for losses on manufacturing commitments in excess of forecasted demand. Alternatively, insufficient supply levels may lead to shortages that result in delayed product revenue or loss of sales opportunities altogether as potential MSP partners turn to competitors’ products that are readily available. If we are unable to effectively manage our supply and inventory, our operating results could be adversely affected.

Because some of the key components in our products come from limited sources of supply, we are susceptible to supply shortages or supply changes, which could disrupt or delay our scheduled product deliveries to our end-users and may result of in the loss of sales or a loss of MSP partner relationships.

Our products rely on key components, including our networking hardware such as access points, switches and routers, which our manufacturing partners purchase on our behalf from a limited number of component suppliers. The manufacturing operations of some of our component suppliers are geographically concentrated in Asia and elsewhere, which makes our supply chain vulnerable to regional disruptions, such as natural disasters, fire, political instability, civil unrest, a power outage or a localized health risk, and as a result could impair the volume of components that we are able to obtain.

Further, we do not have volume purchase contracts with any of our component suppliers, and they could cease selling to us at any time following the completion of an accepted purchase order. If we are unable to obtain a sufficient quantity of these components in a timely manner for any reason, sales of our products could be delayed or halted or we could be forced to expedite shipment of such components or our products at dramatically increased costs. Our component suppliers also change their selling prices frequently in response to market trends, including industry-wide increases in demand, and because we do not have volume purchase contracts with these component suppliers, we are susceptible to price fluctuations related to raw materials and components and may not be able to adjust our prices accordingly. Additionally, poor quality in any of the sole-sourced components in our products could result in lost sales or sales opportunities.

If we are unable to obtain a sufficient volume of the necessary components for our products on commercially reasonable terms or the quality of the components do not meet our requirements, we could also be forced to redesign our products and procure new components from alternate component suppliers. The resulting stoppage or delay in selling our products and the expense of redesigning our products could result in lost sales opportunities and damage to partner relationships, lawsuits and subject us to unclear liabilities and limits, which would adversely affect our business and operating results.

Our ability to sell our products and subscriptions is dependent on the quality of our technical support services and those of our MSP partners, and the failure to offer high-quality technical support services could have a material adverse effect on our MSP partners’ or their SMB customers’ satisfaction with our products and subscriptions, thereby causing MSP partners to purchase less of our products and subscriptions, which would adversely affect our business financial condition and operating results.

After our products and subscriptions are deployed within its network, an SMB depends on our MSP partners’ technical support services to resolve any issues relating to our products and realize the full benefits that our offerings provide. Although we make available to our MSP partners training materials in relation to our products, and we provide substantial customer support to our MSP partners to troubleshoot technical issues, SMB customers may not be satisfied with the service provided by our MSP partners. Our MSP partners often provide similar technical support for third-parties’ products, and may therefore have fewer resources to dedicate to the support of our products and subscriptions. If we or our MSP partners do not effectively assist our SMB customers in deploying our products and subscriptions, succeed in helping the SMB customers quickly resolve post-deployment issues or provide effective ongoing support, our ability to renew and expand our subscriptions with existing MSP partners would be adversely affected and our reputation with potential MSP partners could be damaged. Additionally, if our MSP partners do not effectively provide support to the satisfaction of their SMB customers, we may be required to provide direct support to such customers, which would require us to hire additional personnel and to invest in additional resources. It can take several months to recruit, hire and train qualified technical support employees. We may not be able to hire such resources fast enough to keep up with unexpected demand, particularly if the sales of our products exceed our internal forecasts. As a result, our ability and the ability of our MSP partners to provide adequate and timely support to their SMB customers will be negatively impacted, and customers’ satisfaction with our products and subscriptions will be adversely affected. Additionally, to the extent that we may need to rely on our sales engineers to provide post-sales support while we are ramping our support resources, our sales productivity will be negatively impacted, which would harm our revenues. Our failure or our MSP partners’ failure to provide and maintain high-quality support services could have a material adverse effect on our business, financial condition and operating results.

Table of Contents

If we fail to meet contractual commitments related to response time, service level commitments relating to our endpoint management and business management tools or quality of professional services, we could be obligated to provide credits for future service, or face contract termination, which could adversely affect our business, operating results and financial condition.

Certain of our agreements contain service level agreements for our endpoint management and business management tools, under which we guarantee specified availability of our products and solutions. If we are unable to meet the stated service level commitments to our partners or suffer extended periods of unavailability of our products or solutions, we may be obligated to provide affected partners with service credits or partners could elect to terminate and receive refunds for prepaid amounts. Any failure to meet these contractual commitments could adversely affect our revenue, operating results and financial condition and any failure to meet service level commitments or extended service outages of our product offerings could adversely affect our business and reputation as partners may elect not to renew and we could lose future sales.

Our relatively limited operating history makes it difficult to evaluate our current business and prospects and may increase the risk that we will not be successful.

Our relatively limited operating history makes it difficult to evaluate our current business and prospects and plan for our future growth. We were founded in 2007, with much of our growth occurring in recent years. As a result, our business model has not been fully proven, which subjects us to a number of uncertainties, including our ability to plan for and model future growth. We have encountered and will continue to encounter risks and uncertainties frequently experienced by rapidly growing companies in developing markets, including our ability to achieve broad market acceptance of our products and services, attract additional MSP partners, withstand increasing competition and manage increasing expenses as we continue to grow our business. If our assumptions regarding these risks and uncertainties are incorrect or change in response to changes in the market for our products and services, our operating and financial results could differ materially from our expectations and our business could suffer.

Acquisitions present many risks that could have a material adverse effect on our business and results of operations.

In order to expand our business, we have made several acquisitions and expect to continue acquiring or investing in businesses, joint ventures, products and platform capabilities or technologies that we believe could complement or expand our offerings, enhance our technical capabilities or otherwise offer growth opportunities. The success of our future growth strategy will depend on our ability to identify, negotiate, complete and integrate acquisitions and, if necessary, to obtain satisfactory debt or equity financing to fund those acquisitions. Acquisitions are inherently risky, and any acquisitions we complete may not be successful. Our past acquisitions and any mergers and acquisitions that we may undertake in the future involve numerous risks, including, but not limited to, the following:

•diversion of our management’s attention from normal daily operations of our business;

•our inability to maintain the key business relationships and the reputations of the businesses we acquire;

•uncertainty of entry into markets in which we have limited or no prior experience and in which competitors have stronger market positions;

•our dependence on unfamiliar affiliates, resellers, distributors and partners of the companies we acquire;

•our inability to increase revenue from an acquisition for a number of reasons, including our failure to drive demand in our existing partner base for acquired products and our failure to obtain renewals or upgrades and new product sales from customers of the acquired businesses;

•charges to our operating results from expenses incurred to effect the acquisition;

•increased costs related to acquired operations and continuing support and development of acquired products;

•changes in the fair value of any contingent consideration;

•charges to our operating results because of duplicative pre-merger activities;

•costs incurred to combine the operations of companies we acquire, such as transitional employee expenses and employee retention or relocation expenses;

•potential loss of key employees of the companies we acquire;

•our responsibility for the liabilities of the businesses we acquire;

•identification of, or changes to, assumed contingent liabilities;

•charges to our operating results resulting from the expensing of certain stock awards assumed in an acquisition;

Table of Contents

•potential goodwill and intangible asset impairment charges, including a reduction in the useful lives of intangible assets acquired, and amortization associated with acquired businesses;

•long-lived asset impairment charges;

•adverse tax consequences associated with acquisitions;

•changes in how we are required to account for our acquisitions under U.S. generally accepted accounting principles, including arrangements that we assume from an acquisition;

•potential negative perceptions of our acquisitions by partners, financial markets or investors;

•failure to obtain required approvals from governmental authorities under competition and antitrust laws on a timely basis, if at all, which could, among other things, delay or prevent us from completing a transaction, or otherwise restrict our ability to realize the expected financial or strategic goals of an acquisition;

•potential increases in our interest expense, leverage and debt service requirements if we incur additional debt to pay for an acquisition; and

•our inability to apply and maintain our internal standards, controls, procedures and policies to acquired businesses.

Acquisitions or asset purchases made entirely or partially for cash may reduce our cash reserves or require us to incur additional debt under our credit agreements or otherwise. We may seek to obtain additional cash to fund an acquisition by selling equity or debt securities. We may be unable to secure the equity or debt funding necessary to finance future acquisitions on terms that are acceptable to us. If we finance acquisitions by issuing equity or convertible debt securities, our existing stockholders will experience ownership dilution.

Additionally, when we acquire businesses, we allocate the purchase price to tangible assets and liabilities and identifiable intangible assets acquired at their acquisition date fair values. Any residual purchase price is recorded as goodwill, which is also generally measured at fair value. We also estimate the fair value of any contingent consideration. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are uncertain and involve significant judgments by management.

The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition or cash flows, particularly in the case of a larger acquisition or substantially concurrent acquisitions. Changes to our operating results in any given period could differ substantially from other periods based on the timing and size of our acquisitions and the extent of integration activities.

We may become involved in litigation that may materially adversely affect us.

From time to time, we may become involved in various legal proceedings relating to matters incidental to the ordinary course of our business, including patent and other intellectual property claims, commercial, product liability, employment, class action, whistleblower and other litigation and claims and governmental and other regulatory investigations and proceedings. Such matters can be time-consuming, divert management’s attention and resources, cause us to incur significant expenses or liability and/or require us to change our business practices. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect our results of operations. Because of the potential risks, expenses and uncertainties of litigation, we may, from time to time, settle disputes, even where we have meritorious claims or defenses, by agreeing to settlement agreements. Because litigation is inherently unpredictable, we cannot be certain that the results of any of these actions will not have a material adverse effect on our business, financial condition, results of operations and prospects.

If we are unable to sustain market recognition of and loyalty to our brand, or if our reputation were to be harmed, we could lose partners or fail to increase the number of our partners, which could harm our business, financial condition and operating results.

Given our market focus, maintaining and enhancing the “Datto” brand among MSPs is critical to our success. We believe that the importance of brand recognition and loyalty among MSPs will increase in light of increasing competition in our markets. We plan to continue investing substantial resources to promote our brand to MSPs, both domestically and internationally, but there is no guarantee that our brand development strategies will enhance the recognition of our brand. Some of our existing and potential competitors have well-established brands with greater general recognition than we have. If our efforts to promote and maintain our brand are not successful, our operating results and our ability to attract and retain partners may be adversely affected. In addition, even if our brand recognition and loyalty increases, this may not result in increased use of our solutions or higher revenue. Additionally, if our MSP partners do not use or ineffectively use our solutions to serve their SMB customers, our reputation and ability to grow our business may be harmed.

Table of Contents

Our solutions, as well as those of our competitors, are regularly reviewed in computer and business publications. Negative reviews, or reviews in which our competitors’ solutions and services are rated more highly than our solutions, could negatively affect our brand and reputation in the view of MSPs. From time-to-time, our partners express dissatisfaction with our solutions, including, among other things, dissatisfaction with our customer support, our billing policies and the way our solutions operate. If we do not handle partner complaints effectively, our brand and reputation may suffer, we may lose our partners’ confidence and they may choose not to renew their subscriptions. In addition, many of our MSP partners participate in online blogs about computers and internet services, and software and technology, including our solutions, and our success depends in part on our ability to generate positive feedback through such online channels where MSP partners seek and share information. If actions that we take or changes that we make to our solutions upset these MSP partners, their blogging could negatively affect our brand and reputation. Complaints or negative publicity about our solutions or billing practices could adversely impact our ability to attract and retain partners and our business, financial condition and operating results.

If we cannot maintain our corporate culture as we grow, our business may be harmed.

We believe that our corporate culture has been a critical component to our success and that our culture creates an environment that drives our employees and perpetuates our overall business strategy. We have invested substantial time and resources in building our team and we expect to continue to hire aggressively as we expand, including with respect to our international operations. As we grow and mature as a public company and grow internationally, we may find it difficult to maintain our corporate culture. We face additional challenges in maintaining our culture as most of our employees have worked remotely for an extended period of time during the COVID-19 pandemic, with a growing number of new employees only experiencing Datto culture while working from home. Any failure to preserve our culture could negatively affect our future success, including our ability to recruit and retain personnel and effectively focus on and pursue our business strategy.

Foreign currency exchange rate fluctuations could harm our financial results.

We conduct significant transactions, including revenue transactions and intercompany transactions, in currencies other than the U.S. Dollar or the functional operating currency of the transactional entities. In addition, our international subsidiaries maintain significant net assets that are denominated in currencies other than the functional operating currencies of these entities. Accordingly, changes in the value of currencies relative to the U.S. Dollar may impact our consolidated revenues and operating results because of transactional and translational remeasurement that is reflected in our earnings. It is particularly difficult to forecast any impact from exchange rate movements, so there is risk that unanticipated currency fluctuations could adversely affect our financial results or cause our results to differ from investor expectations or our own guidance in any future periods. In addition, the announcement of Brexit adversely impacted global markets, including currencies, and resulted in a decline in the value of the British pound, as compared to the U.S. Dollar and other currencies. Volatility in exchange rates and global financial markets is expected to continue as a result of a number of factors, including uncertainty surrounding Brexit and the recent political and economic uncertainty globally.

Our indemnification obligations and limitations of our director and officer liability insurance may have a material adverse impact on our financial condition, results of operations and cash flows.

Under Delaware law, our certificate of incorporation, our bylaws and certain indemnification agreements to which we are a party, we have an obligation to indemnify, or we have otherwise agreed to indemnify, certain of our current and former directors and officers with respect to past, current and future investigations and litigation.

The scope of our indemnification obligations may be broader than the coverage available under our directors’ and officers’ liability insurance, or there may be insufficient coverage available. Further, in the event the directors and officers are ultimately determined not to be entitled to indemnification, we may not be able to recover any amounts we previously advanced to them.

We cannot provide any assurances that future indemnification claims, including the cost of fees, penalties or other expenses, will not exceed the limits of our insurance policies, that such claims are covered by the terms of our insurance policies or that our insurance carrier will be able to cover such claims. Further, should a coverage dispute arise, we may also incur significant expenses in relation to litigating or attempting to resolve any such dispute. Accordingly, we may incur significant unreimbursed costs to satisfy our indemnification obligations, which may have a material adverse impact on our financial condition, results of operations or cash flows.

We previously identified a material weakness in our internal control over financial reporting and may identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, which may result in material misstatements of our financial statements or cause us to fail to meet our periodic reporting obligations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control. Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, requires that we evaluate and

Table of Contents

determine the effectiveness of our internal control over financial reporting, and our independent registered public accounting firm is required to audit such internal control. In connection with the audit of our financial statements as of and for the fiscal year ended December 31, 2020, we and our independent registered public accounting firm identified a material weakness in our internal control over financial reporting, which was remediated over the course of 2021.

Even if the previously disclosed material weakness has been remediated, completion of remediation does not provide assurance that our remediation or other controls will continue to operate properly. If we are unable to maintain effective internal control over financial reporting or disclosure controls and procedures, our ability to record, process and report financial information accurately, and to prepare financial statements within required time periods could be adversely affected, which could subject us to litigation or investigations requiring management resources and payment of legal and other expenses, negatively affect investor confidence in our financial statements and adversely impact our stock price.

We may experience difficulties in continuing to implement our enterprise resource planning system over the next few years.

We are engaged in a multi-year implementation of an enterprise resource planning, or ERP, system. Such an implementation is a major undertaking from a financial, management and personnel perspective. The implementation of the ERP system may prove to be more difficult, costly or time consuming than expected, and there can be no assurance that this system will continue to be beneficial to the extent anticipated. Any disruptions, delays or deficiencies in the design and implementation of our ERP system could adversely affect our ability to process orders, ship products, send invoices and track payments, fulfill contractual obligations, produce financial reports or otherwise operate our business. As we continue to implement our ERP system, our exposure to system attacks may be elevated because we will be running old and new processes in parallel and must simultaneously protect both the new system and legacy systems. If we are unable to implement the ERP system smoothly or successfully, or we otherwise do not capture anticipated benefits, our business, results of operations and financial condition for future periods could be negatively impacted. Additionally, our implementation of the ERP system involves greater utilization of third-party “cloud” computing services in connection with our business operations. Problems faced by us or our third-party “cloud” computing providers, including technological or business-related disruptions, as well as cybersecurity threats, could adversely impact our business, results of operations and financial condition for future periods.

Changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and affect our reported results of operations.

A change in accounting standards or practices can have a significant effect on our reported results and may even affect our reporting of transactions completed before the change is effective. New accounting pronouncements and varying interpretations of accounting pronouncements have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way in which we conduct our business.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below expectations of securities analysts and investors.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes.

Additionally, we base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors. Significant assumptions and estimates used in preparing our consolidated financial statements include those related to revenue recognition, stock-based compensation, allowance for doubtful accounts, allowance for excess or obsolete inventory, useful lives and recoverability of our long-lived assets, recoverability of our goodwill, and income taxes, including the realizability of deferred tax assets and uncertain tax positions.

Our international operations may give rise to potentially adverse tax consequences.

Our corporate structure and associated transfer pricing policies anticipate future growth into international markets. The amount of taxes we pay related to different jurisdictions may depend on the application of the tax laws of the various jurisdictions, including the United States, to our international business activities, changes in tax rates, new or revised tax laws or interpretations of existing tax laws and policies and our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for pricing intercompany transactions, which are generally required to be computed on an arm’s-length basis pursuant to intercompany arrangements, or disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a challenge or disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax

charges, higher effective tax rates, reduced cash flows and harm to our results of operations and financial condition. Our financial statements could fail to reflect adequate reserves to cover such a contingency.

Changes in tax laws or regulations in the various tax jurisdictions we are subject to that are applied adversely to us or our partners could increase the costs of our solutions and harm our business.

We are subject to tax in the U.S. and numerous international jurisdictions. Comprehensive tax reform legislation in any of the jurisdictions in which we operate could significantly increase our effective tax rate and may have an adverse impact on our results of operations, cash flows and financial condition. In addition, new income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time. Those enactments could harm our domestic and international business operations, and our business and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. These events could require us or our partners to pay additional tax amounts on a prospective or retroactive basis, as well as require us or our partners to pay fines and/or penalties and interest for past amounts deemed to be due. If we raise our prices to offset the costs of these changes, existing and potential future partners may elect not to purchase our solutions in the future. Additionally, new, changed, modified or newly interpreted or applied tax laws could increase our partners’ and our compliance, operating and other costs, as well as the costs of our solutions. Further, these events could decrease the capital we have available to operate our business. Any or all of these events could harm our business and financial performance.

Our ability to utilize our net operating loss carryforwards may be limited.

Our ability to utilize our federal net operating loss carryforwards may be limited under Section 382 of the Code. The limitations apply if we experience an “ownership change,” which is generally defined as a greater than 50 percentage point change (by value) in the ownership of our equity by certain stockholders over a rolling three-year period. Similar provisions of state tax law may also apply to limit the use of our state net operating loss carryforwards. Future changes in our stock ownership, which may be outside of our control, may trigger an ownership change and, consequently, the limitations under Section 382 of the Code. As a result, our ability to use our pre-change net operating loss carryforwards to offset future taxable income may be subject to limitations, which could adversely affect our future cash flows.

In addition, our ability to use our federal, state and foreign net operating losses to offset potential future taxable income and related income taxes that would otherwise be due is dependent upon our generation of future taxable income before the expiration dates of the net operating losses, and we cannot predict with certainty when, or whether, we will generate sufficient taxable income to use all of our net operating losses. Federal net operating losses generated prior to 2018 will continue to be governed by the net operating loss carryforward rules as they existed prior to the adoption of the Tax Cuts and Jobs Act of 2017, or the Tax Act, which means that generally they will expire 20 years after they were generated if not used prior thereto. Many states have similar laws. Accordingly, our federal and state net operating losses could expire unused and be unavailable to offset future income tax liabilities. Moreover, federal net operating losses generated in tax years ending after December 31, 2017 may be carried forward indefinitely, but the deductibility of such federal net operating losses may be limited to 80% of current year taxable income for tax years beginning after December 31, 2020. Refer to Note 15. Income Taxes to the consolidated financial statements for further discussion of net operating loss carryforwards as of December 31, 2021.

Risks Related to Systems and Intellectual Property

Our software, website, hardware, hosted and internal systems may be subject to intentional or accidental disruption or penetration from external attackers or insiders that could adversely impact our reputation and future sales. If our end-users or third-party service providers experience data losses, security incidents and breaches via our products or solutions, our brand, reputation and business could be harmed.

Our MSP partners rely on our archiving and other solutions to protect, transfer or store the corporate data of their SMB customers, which may include financial records, credit card information, business information, health information, other personally identifiable information or other sensitive personal information. Due to the nature of our business and our storage of this sensitive data, we have previously and could be in the future a target of, or subject to, a wide variety of attacks or security incidents. In addition to threats from traditional computer “hackers,” malicious code (such as malware, viruses, trojans, worms and ransomware), employee theft or misuse, password spraying, phishing, credential stuffing and denial-of-service attacks, we also face threats from sophisticated organized crime, nation-state and nation-state supported actors who engage in attacks (including advanced persistent threat intrusions) that add to the risks our internal systems and our MSP partners’ systems, as well as the virtualized systems of our MSP partners and the information that those systems store and process. We could also experience security incidents resulting from non-malicious but incorrect actions (or inactions) of our employees or business partners that could affect our security.

Despite significant efforts to create barriers to such security threats, it is virtually impossible for us to entirely mitigate these risks, especially where they are attributable to the behavior of independent third parties beyond our control. The security measures we have

Table of Contents

implemented or integrated into our internal systems and networks, which are designed to detect unauthorized activity and prevent or minimize security breaches, may not function as expected or may not be sufficient to protect us against certain attacks. Furthermore, the relative cost and operational requirements associated with maintaining such barriers may increase in the future. We are also subject to additional data security requirements relating to our acceptance of credit card and debit card payments. If we fail to comply with the rules or requirements of any provider of a payment method we accept, if the volume of fraud in our transactions limits or terminates our rights to use payment methods we currently accept, or if a data breach occurs relating to our payment systems, we may, among other things, be subject to fines or higher transaction fees and may lose, or face restrictions placed upon, our ability to accept credit card and debit card payments from customers or facilitate other types of online payments.

Experienced computer hackers may attempt to penetrate our infrastructure or applications as a result of an inadequate security posture or ineffective controls (i.e. missing patches, technology failures, etc.) or attempt to trick our employees into taking actions that compromise our security (such as via phishing or business email compromise attacks) in order to misappropriate proprietary information and/or cause interruptions of our services and/or expose perceived security vulnerabilities. It is also possible that systems may be disrupted or our sensitive information or the information of our SMBs might be exposed because of malfeasance or errors by employees or contractors.

In addition, techniques used to sabotage or to obtain unauthorized access to systems and networks in which data is stored, or through which data is transmitted, change frequently and generally are not recognized until launched against a target. As a result, it may not be possible for us to anticipate these techniques or implement adequate preventative measures to prevent an electronic intrusion into our systems and networks and we may be required to expend significant capital and financial resources to protect against such threats or to alleviate problems caused by breaches in systems, network or data security. If an actual or perceived breach of network security occurs as a result of third-party action, including cyber-attacks or other intentional misconduct by computer hackers, error or malfeasance by insiders, or otherwise, it could adversely affect the market perception of our company and our solutions, reduce demand for our solutions, cause a significant number of our MSP partners to terminate their monthly subscriptions and thereby cause significant revenue loss and may expose us to data loss, litigation and possible liability including fines, penalties and damages. In addition, such a security breach could impair our ability to operate our business, including our ability to provide support services to our MSP partners.

Third parties may attempt to fraudulently induce employees, contractors or partners into disclosing sensitive information such as usernames, passwords or other information. Third parties may also compromise the security of our internal electronic systems, networks and/or physical facilities or those of our partners, in order to gain access to our data or the data of our MSP partners or their SMB customers. Our MSP partners may also disclose or lose control of their API keys, secrets or passwords, or use the same or similar secrets or passwords on third-parties’ systems, which could lead to unauthorized access to their accounts (arising from, for example, an independent third-party data security incident that compromises those API keys, secrets or passwords). Through such means, as well as others, our MSP partners or their SMB customers may experience a data loss and/or breach in their own IT infrastructure and a number of our Unified Continuity partners do not adhere to security best practices (i.e. have secondary replication enabled, etc.) such that the data they back up could be destroyed or compromised if the physical device they possess is directly impacted by the loss and/or breach event.

Security breaches impacting us could result in a risk of loss, unavailability or unauthorized disclosure of sensitive SMB customer information, which, in turn, could lead to significant legal and financial exposure, regulatory or government audits and investigations and possible liability (including regulatory fines), a loss of confidence in our security, interruptions or malfunctions in our operations. Ultimately, any of these consequences could have a negative impact on our ability to attract new MSP partners and to grow or maintain our revenue. Specifically, loss of confidence in our operations and products may cause a significant portion of our MSP partners to terminate their monthly subscriptions, thereby causing a significant decrease in revenue. Furthermore, any such breach, including a breach of the systems or networks of our third-party suppliers or integrators, could compromise our systems or networks, creating system disruptions or slowdowns and exploiting security vulnerabilities of our networks, or the networks of our MSP partners, and the information stored on our network or the networks of our partners could be accessed, publicly disclosed, altered, lost or stolen, which could subject us to liability and cause us financial harm. These breaches, or any perceived breach, of our systems or networks or the systems of our partners, whether or not any such breach is because of our vulnerability, may also undermine confidence in us or our industry and result in damage to our reputation, negative publicity, loss of partners and sales, increased costs to remedy any problem and costly litigation or regulatory fines.

Our insurance coverage, covering certain security and privacy damages, may be inadequate or may not be available in the future on acceptable terms, or at all. In addition, our policy may not cover any claim against us for loss of data or other indirect or consequential damages. Defending a suit based on any data loss or system disruption, regardless of its merit, could be costly and divert management’s attention.

If Microsoft or Google were to restrict access to the application programming interfaces, or APIs, we rely on in order to back up Microsoft 365 and Google Workspace, our operating results could be harmed.

We work with Microsoft and Google to make efficient use of Microsoft 365 and Google Workspace APIs in order to efficiently consume data and restore services. If Microsoft or Google were to make these APIs (or similar APIs for successor products) unavailable to companies like Datto, we would not have an alternate solution to backup Microsoft 365 and Google Workspace. As a result, our operating results and revenue may be harmed if MSPs decline to renew their subscriptions with us as a result of our inability to backup Microsoft 365 and Google Workspace.

Defects, failures, vulnerabilities or lack of availability in our or our third-parties’ software, solutions, infrastructure and hardware could harm our reputation, reduce the sales of our solutions and expose us to liability for losses.

Because our software, solutions, infrastructure and hardware are complex, undetected errors, failures or bugs may occur, especially when new software, solutions, infrastructure and hardware are first introduced or when new versions or updates are released, or when we introduce an acquired company’s solutions or services, despite our efforts to test those solutions and enhancements prior to release. This includes not only vulnerabilities that are specific to our software, solutions, infrastructure and hardware, but also vulnerabilities that impact the third-party or open source software that we use or the hardware that we rely on. In addition, to the extent that we do not effectively address capacity constraints, upgrade our infrastructure and systems as needed, our business, financial condition and results of operations may be adversely affected. We may not be able to correct defects, errors, vulnerabilities or failures promptly, or at all.

Any defects, errors, vulnerabilities or failures in our software, solutions, infrastructure and hardware or in third-party software, solutions, infrastructure or hardware that we rely on could result in:

•expenditure of significant financial and development resources in efforts to analyze, correct, eliminate or work around errors or defects or to address and eliminate vulnerabilities;

•loss of existing or potential partners or loss of partner confidence, including a widespread loss of partners simultaneously;

•loss or disclosure of our SMB customers’ confidential information or the inability to access such information;

•loss of our proprietary technology;

•our solutions being susceptible to hacking or electronic break-ins or otherwise failing to secure data;

•delayed or lost revenue, particularly in relation our BCDR solutions, which comprise a significant portion of our revenue;

•delay or failure to attain market acceptance;

•lost market share;

•negative publicity, which could harm our reputation; or

•litigation, regulatory inquiries or investigations that would be costly and harm our reputation.

In particular, because we utilize various types of software and other technology, as well as intellectual property rights, licensed from unaffiliated third parties in order to provide and improve certain elements of our solutions, any errors or defects in any third-party technology could result in errors in our solutions that could harm our business. In addition, licensed technology and intellectual property rights may not continue to be available on commercially reasonable terms, or at all. While we believe that there are currently adequate replacements for the third-party technology we use, any loss of the right to use any of this technology on commercially reasonable terms, or at all, could result in delays in producing or delivering our solutions until equivalent technology is identified and integrated, which delays could harm our business. In this situation we would be required to either redesign our solutions to function with software available from other parties or to develop these components ourselves, which would result in increased costs. Furthermore, we might be forced to limit the features available in our current or future solutions. If we fail to maintain or renegotiate any of these technology or intellectual property licenses, we could face significant delays and diversion of resources in attempting to develop similar or replacement technology, or to license and integrate a functional equivalent of the technology. Our ability to effectively manage our business depends significantly on our information systems and platforms provided by third parties, including Oracle and Amazon. If we are unable to maintain our current relationships with these service providers, there is no assurance that we will be able to locate replacements on a timely basis or on acceptable terms. The failure of our information systems to operate effectively, problems with transitioning to upgraded or replacement systems or expanding them, or a breach in security of these systems, could materially adversely affect the efficiency of our business and operations.

Limitation of liability provisions in our standard terms and conditions and our other agreements may not adequately or effectively protect us from any claims related to defects, errors, vulnerabilities or failures in our solutions or those of the third-parties we rely on, including as a result of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries.

Table of Contents

The material stored on our servers may subject us to negative publicity, legal liability and expenditures.

We are not aware of the contents of the data that MSP partners store using our solutions, including our BCDR products. Our BCDR products operate by taking a complete snapshot of operating systems, applications, emails and other content, which is then encrypted and transmitted to our servers. Our employees generally do not have access to view or monitor what is actually stored within this hybrid cloud solution. To the extent that sensitive, personally identifiable, illegal or controversial data is stored in our servers and that becomes known publicly, it may create negative publicity and cause us to incur legal expenses. In 2015, it was publicized that we had backed up a prominent federal government employee’s personal email account, which contained classified and sensitive emails. While we had no role in monitoring the content or source of data stored by the MSP partners, our involvement in the storage of the emails caused our executive officers and employees to divert time from running the day to day operations of the business in order to cooperate with federal agencies and resulted in some negative press. Furthermore, because we do not monitor the data, we cannot ensure that the usage of our solutions complies with the license terms of the end-users’ software. If their usage of our BCDR products causes them to violate these license terms, the software vendors make seek legal redress from us.

We have no intention to begin monitoring the contents or nature of the data that is being stored through our solutions. Accordingly, because of the storage of sensitive, illegal or controversial material, we may face in the future reputational harm, or harm to our results of operations and financial condition loss of partners, legal proceedings or actions against us by government entities or others.

Interruptions or delays in services provided by our data centers or other third parties could impair the delivery of our service and harm our business.

Our continued growth depends on the ability of our partners to access our solutions 24 hours a day, seven days a week, without any meaningful interruption or degradation of service. We have in the past and may in the future experience disruptions, outages and other performance problems within our infrastructure and our third-party providers’ infrastructure, including:

•cooling system failures that lead to the shutdown of our systems or the overheating of our servers, increasing the likelihood of hardware failures;

•the physical relocation of servers to new facilities, which may cause infrastructure to be damaged, lost or stolen; or

•data centers maintaining inadequate diversity among internet service providers, leading to redundant pathing and possible total facility outages.

We currently lease spaces from data center service providers in the United States, Canada, the United Kingdom, Germany, Iceland, Singapore and Australia and our servers that are stored at these data centers form the basis of the Datto Cloud. In addition to relying on our data center service providers, we also rely on other third parties to maintain our cloud infrastructure and deploy our solutions. Any damage to, or failure or disruption of, the systems of our data centers, including from cyber-attacks, natural disasters, fires, floods, telecommunications failures, power loss or other similar events beyond our control, could result in interruptions to our service or our ability to successfully restore an end-user’s data when needed. The failure of our data centers to meet our capacity requirements could result in interruptions in the availability of our solutions, impair the functionality of our solutions or impede our ability to scale our operations.

As we continue to add data centers, restructure our data management plans and increase capacity in existing and future data centers, we may move or transfer our data and our MSP partners’ data. Despite precautions taken during such processes and procedures, any unsuccessful data transfers may impair the delivery of our service, and we may experience costs or downtime in connection with the transfer of data to other facilities. Similarly, some of our solutions’ features run or depend on IT services run by third parties, such as data feeds or public clouds, and an extended failure of such services might materially and adversely impact our ability to provide our services to our partners. Furthermore, some of our sales and business operations depend in part on third-party IT service providers and if those services were to be unavailable for extended periods of time it might materially and adversely affect our ability to operate.

We also rely on bandwidth providers, Internet service providers, mobile networks and other third-party IT service providers to operate our business, and to deliver our solutions. If we lose the services of one or more of our bandwidth providers, or if these providers experience outages, for any reason, we could experience disruption in delivering our solutions or we could be required to retain the services of a replacement bandwidth provider. Our business also depends on our partners having high-speed access to the Internet in order to purchase our offerings online and obtain access to the Datto portal for MSP partners. Any Internet outages or delays could adversely affect our ability to provide our solutions to our partners.

Our operations rely heavily on the availability of electricity, which also comes from third-party providers. If we were to experience a major power outage or if the cost of electricity were to increase significantly, our operations and financial results could be harmed. If we or our data centers were to experience a major power outage, we or they would have to rely on back-up generators, which might not work properly or might not provide an adequate power supply during a major power outage. Such a power outage could result in a significant disruption of our business.

Table of Contents

The occurrence of an extended interruption of our or third-party services for any reason could result in lengthy interruptions in our services or in the delivery of partners’ email and require us to provide service credits, refunds, indemnification payments or other payments to our partners, and could also result in the loss of partners.

If we fail to integrate our products with a variety of operating systems, software applications, platforms and hardware that are developed by others or ourselves, our products may become less competitive or obsolete and our results of operations would be harmed.

Our products must integrate with a variety of network, hardware and software platforms, including, specifically, new versions of Windows and new file systems such as ReFS, introduced by Microsoft, and we need to continuously modify and enhance our products to adapt to changes in hardware, software, networking, browser and database technologies. We believe a significant component of our value proposition to partners is the ability to optimize and configure our products to integrate with our systems and those of third parties. If we are not able to integrate our products in a meaningful and efficient manner, demand for our products could decrease and our business and results of operations would be harmed.

In addition, we have a large number of products, and maintaining and integrating them effectively requires extensive resources. Our continuing efforts to make our products more interoperative may not be successful. Failure of our products to operate effectively with future infrastructure platforms and technologies could reduce the demand for our products, resulting in partner dissatisfaction and harm to our business. If we are unable to respond to changes in a cost-effective manner, our products may become less marketable, less competitive or obsolete and our business and results of operations may be harmed.

Indemnity provisions in various agreements potentially expose us to substantial liability for intellectual property infringement and other similar claims and losses.

Our agreements with MSP partners and other third parties may include indemnification or other provisions under which we agree to indemnify or otherwise be liable to them for losses suffered or incurred as a result of claims of intellectual property infringement or similar intellectual property rights claims, damages caused by us to property or persons or other liabilities relating to or arising from the use of our hardware, software or services or other acts or omissions. The term of these contractual provisions often survives termination or expiration of the applicable agreement. As we continue to grow, the possibility of infringement claims and other intellectual property rights claims against us may increase. For any intellectual property indemnification claim against us or our partners, we may incur significant legal expenses and may have to pay damages, settlement fees, license fees and/or stop using technology found to be in violation of the third party’s rights. Large indemnity payments could harm our business, results of operations and financial condition. We may also have to seek a license for the infringing (or violative) or allegedly infringing (or violative) technology. Such license may not be available on reasonable terms, if at all, and may significantly increase our operating expenses or may require us to restrict our business activities and limit our ability to deliver certain products. As a result, we may also be required to develop alternative non-infringing (or non-violative) technology, which could require significant effort and expense and/or cause us to alter our hardware or software, which could negatively affect our business.

From time to time, MSP partners may require us to indemnify or otherwise be liable to them. Although we normally contractually limit our liability with respect to such obligations, the existence of such a dispute may have adverse effects on our partner relationship and reputation and we may still incur substantial liability related to them.

Any assertions by a third party, whether or not successful, with respect to such indemnification obligations could subject us to costly and time-consuming litigation, expensive remediation and licenses, divert management attention and financial resources, harm our relationship with that partner and other current and prospective partners, reduce demand for our platform and harm our brand, business, results of operations and financial condition.

Claims by others that we infringe or violate their proprietary technology or other rights, or other lawsuits asserted against us, could result in significant costs and substantially harm our business, financial condition, results of operations and prospects.

A number of companies in our industry hold a large number of patents and also protect their copyright, trade secret and other intellectual property rights, and companies in the networking and security industry frequently enter into litigation based on allegations of patent infringement or other violations of intellectual property rights. In addition, patent holding companies seek to monetize patents they previously developed, have purchased or otherwise obtained. Many companies, including our competitors, may now, and in the future, have significantly larger and more mature patent, copyright, trademark and trade secret portfolios than we have, which they may use to assert claims of infringement, misappropriation and other violations of intellectual property rights against us. In addition, future litigation may involve non-practicing entities (also known as patent trolls) or other patent owners who have no relevant product offerings or revenue and against whom our own patents may therefore provide little or no deterrence or protection. As we face increasing competition and gain an increasingly higher profile, including as a result of becoming a public company, the possibility of intellectual property rights

Table of Contents

claims against us grows. Third parties, including but not limited to patent trolls, have asserted in the past and may in the future assert claims of infringement of intellectual property rights against us and these claims, even without merit, could harm our business, including by increasing our costs, reducing our revenue, creating partner concerns that result in delayed or reduced sales, distracting our management and technical experts from the running of our business and requiring us to cease use of important intellectual property. While we have managed to enter into release and settlement agreements with respect to intellectual property infringement or similar lawsuits brought by and against us, we cannot be certain that the counterparties to these release and settlement agreements will abide by their obligations as set forth in these agreements. In addition, because patents can take years to issue and are often afforded confidentiality for some period of time, there may currently be pending applications, unknown to us, that later result in issued patents that could cover one or more of our services. Moreover, in a patent infringement claim against us, we may assert, as a defense, that we do not infringe the relevant patent claims, that the patent is invalid or both. The strength of our defenses will depend on the patents asserted, the interpretation of these patents and our ability to invalidate the asserted patents. However, we could be unsuccessful in advancing non-infringement and/or invalidity arguments in our defense. In the United States, issued patents enjoy a presumption of validity, and the party challenging the validity of a patent claim must present clear and convincing evidence of invalidity, which is a high burden of proof. Conversely, the patent owner need only prove infringement by a preponderance of the evidence, which is a lower burden of proof. Furthermore, because of the substantial amount of discovery required in connection with patent and other intellectual property rights litigation, there is a risk that some of our confidential information could be compromised by the discovery process.

If we are not successful in defending against third-party claims that arise, we could be required to pay substantial damages for past and future sales and/or licensing of our services, enjoined from making, using, selling or otherwise offering our services if a license or other right to continue selling our services is not made available to us, and required to pay substantial ongoing royalties and comply with unfavorable terms even if such a license is made available to us. Any of these outcomes could result in a material adverse effect on our business. Even if we were to prevail, these lawsuits, and any other third-party infringement claims, could be costly and time-consuming, divert the attention of our management and key personnel from our business operations, deter MSP partners from selling or licensing our services and dissuade potential partners from purchasing our services, which would also materially harm our business. In addition, any public announcements of the results of any proceedings in these or other third-party infringement claims could be negatively perceived by industry or financial analysts and investors and could cause our stock price to experience volatility or decline. The expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect our results of operations.

As the number of products and competitors in our market increases and overlaps occur, claims of infringement, misappropriation and other violations of intellectual property rights may increase. Our insurance may not cover intellectual property rights infringement claims or other claims related to violations of intellectual property rights. Third parties have in the past and may in the future also assert infringement or similar claims against our MSP partners, with whom our agreements may obligate us to indemnify against these claims. In addition, to the extent we hire personnel from competitors, we may be subject to allegations that such employees have divulged proprietary or other confidential information to us.

In the event that we fail to successfully defend ourselves against an infringement claim or similar intellectual property rights claim, a successful claimant could secure a judgment or otherwise require payment of legal fees, settlement payments, ongoing royalties or other costs or damages; or we may agree to a settlement that prevents us from offering certain services or features; or we may be required to obtain a license, which may not be available on reasonable terms, or at all, to use the relevant technology. If we are prevented from using certain technology or intellectual property, we may be required to develop alternative, non-infringing (or non-violative) technology, which could require significant time, during which we could be unable to continue to offer our affected services or features, effort and expense and may ultimately not be successful.

From time to time, the U.S. Supreme Court, other U.S. federal courts and the U.S. Patent and Trademark Appeals Board, and their foreign counterparts, have made and may continue to make changes to the interpretation of patent laws in their respective jurisdictions. We cannot predict future changes to the interpretation of existing patent laws or whether U.S. or foreign legislative bodies will amend such laws in the future. Any changes may lead to uncertainties or increased costs and risks surrounding the outcome of third-party intellectual property rights claims brought against us and the actual or enhanced damages, including treble damages, that may be awarded in connection with any such current or future claims and could have a material adverse effect on our business and financial condition.

Any of these events could materially and adversely harm our business, financial condition and results of operations.

The success of our business depends in part on our ability to protect and enforce our intellectual property rights.

We believe our intellectual property is an essential asset of our business and our success and ability to compete depend in part upon protection of our intellectual property rights. We rely on a combination of patent, copyright, trademark and trade secret laws, as well as confidentiality procedures and contractual provisions, to establish and protect our intellectual property rights, all of which provide only limited protection. The efforts we have taken to protect our intellectual property rights may not be sufficient or effective, and our patents, trademarks and copyrights may be held invalid or unenforceable. Moreover, we cannot assure you that any patents will be issued with

Table of Contents

respect to our currently pending patent applications in a manner that gives us adequate defensive protection or competitive advantages, or that any patents issued to us will not be challenged, invalidated or circumvented. We have filed for patents in the United States and in certain non-U.S. jurisdictions, but such protections may not be available in all countries in which we operate or in which we seek to enforce our intellectual property rights, or may be difficult to enforce in practice. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, many countries limit the enforceability of patents against certain third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit. Moreover, we may need to expend additional resources to defend our intellectual property rights in these countries, and our inability to do so could impair our business or adversely affect our international expansion. Our currently issued patents and any patents that may be issued in the future with respect to pending or future patent applications may not provide sufficiently broad protection or they may not prove to be enforceable in actions against alleged infringers. Additionally, the U.S. Patent and Trademark Office and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process and to maintain issued patents. There are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If this occurs, it could materially harm our business, operating results, financial condition and prospects.

We believe that our trademarks are integral to our business and our success in building our brand image and customer loyalty. We rely on trademark registrations and common law trademark rights to protect the distinctiveness of our brand and have registered, or have applied to register, those trademarks that we believe are important to our business with the United States Patent and Trademark Office. We cannot assure you that our applications will be approved or that these registrations will prevent imitation of our name or the infringement or other violation of our other intellectual property rights by others. Third parties may also oppose our trademark applications or otherwise challenge our use of the trademarks. Imitation of our name or website design in a manner that projects lesser quality or carries a negative connotation of our brand image could have a material adverse effect on our business, financial condition and results of operations.

We may not be effective in policing unauthorized use of our intellectual property rights, and even if we do detect infringements or other violations, litigation may be necessary to enforce our intellectual property rights. In addition, our intellectual property may be stolen, including by cybercriminals, and we may not be able to identify the perpetrators or prevent the exploitation of our intellectual property by our competitors or others. Protecting against the unauthorized use of our intellectual property rights, technology and other proprietary rights is expensive and difficult, particularly outside of the United States. Any enforcement efforts we undertake, including litigation, could be time-consuming and expensive and could divert management’s attention, either of which could harm our business, operating results and financial condition. Further, attempts to enforce our rights against third parties could also provoke these third parties to assert their own intellectual property or other rights against us, or result in a holding that invalidates or narrows the scope of our rights, in whole or in part. The inability to adequately protect and enforce our intellectual property and other proprietary rights could seriously harm our business, operating results, financial condition and prospects. Even if we are able to secure our intellectual property rights, we cannot assure you that such rights will provide us with competitive advantages or distinguish our services from those of our competitors or that our competitors will not independently develop similar technology, duplicate any of our technology or design around our patents.

Our ability to provide services to our partners depends on our partners’ continued high-speed access to the internet and the continued reliability of the internet infrastructure.

Our business depends on our MSP partners’ continued high-speed access to the internet, as well as the continued maintenance and development of the internet infrastructure. The future delivery of our solutions will depend on third-party internet service providers to expand high-speed internet access, to maintain a reliable network with the necessary speed, data capacity and security and to develop complementary solutions and services, including high-speed modems, for providing reliable and timely internet access and services. All of these factors are out of our control. To the extent that the internet continues to experience an increased number of users, frequency of use or bandwidth requirements, the internet may become congested and be unable to support the demands placed on it, and its performance or reliability may decline. Any internet outages or delays could adversely affect our ability to provide services to our partners.

Currently, internet access is provided by telecommunications companies and internet access service providers that have significant and increasing market power in the broadband and internet access marketplace. In the absence of government regulation, these providers could take measures that affect their customers’ ability to use our products and services, such as attempting to charge their customers more for using our products and services. To the extent that internet service providers implement usage-based pricing, including meaningful bandwidth caps, or otherwise try to monetize access to their networks, we could incur greater operating expenses and partner acquisition and retention could be negatively impacted. Furthermore, to the extent network operators were to create tiers of internet access service and either charge us for or prohibit our services from being available to our partners through these tiers, our business could be negatively impacted. Some of these providers also offer products and services that directly compete with our own offerings, which could potentially give them a competitive advantage.

Our use of open source software in our products and subscriptions could negatively affect our ability to sell our products and subscriptions and subject us to possible litigation.

Our products and subscriptions contain software modules licensed to us by third-party authors under “open source” licenses. Some open source licenses contain requirements that we make available applicable source code for modifications or derivative works we create based upon the type of open source software we use. If we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software to the public. This would allow our competitors to create similar products or subscriptions with lower development effort and time and ultimately could result in a loss of product sales for us.

Although we monitor and are mindful of our use of open source software to avoid subjecting our products and subscriptions to conditions we do not intend, the terms of many open source licenses have not been interpreted by United States courts, and there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our products and subscriptions. From time to time, there have been claims against companies that distribute or use open source software in their products and subscriptions, asserting that open source software infringes the claimants’ intellectual property rights. We could be subject to suits by parties claiming infringement of intellectual property rights in what we believe to be licensed open source software. If we are held to have breached the terms of an open source software license, we could be required to seek licenses from third parties to continue offering our products and subscriptions on terms that are not economically feasible, to reengineer our products and subscriptions, to discontinue the sale of our products and subscriptions if reengineering could not be accomplished on a timely basis or to make generally available, in source code form, our proprietary code, any of which could adversely affect our business, operating results and financial condition.

In addition to risks related to license requirements, usage of open source software can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or assurance of title or controls on origin of the software. In addition, many of the risks associated with usage of open source software, such as the lack of warranties or assurances of title, cannot be eliminated, and could, if not properly addressed, negatively affect our business. We have established processes to help alleviate these risks, including a review process for screening requests from our development organizations for the use of open source software, but we cannot be sure that our processes for controlling our use of open source software in our products and subscriptions will be effective.

Risks Related to Regulatory Compliance

We are subject to governmental export controls and economic sanctions laws that could impair our ability to compete in international markets and subject us to liability if we are not in full compliance with applicable laws.

Certain of our products are subject to U.S. export controls, including the U.S. Department of Commerce’s Export Administration Regulations and economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Control. These regulations may limit the export of our products and provision of our services outside of the United States, or may require export authorizations, including by a license exception or other appropriate government authorizations, including annual or semi-annual reporting and the filing of an encryption registration. Export control and economic sanctions laws may also include prohibitions on the sale or supply of certain of our products to embargoed or sanctioned countries, regions, governments, persons and entities. In addition, various countries regulate the importation of certain products, through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our products. The exportation, re-exportation and importation of our products and the provision of services, including by our partners, must comply with these laws or else we may be adversely affected, through reputational harm, government investigations, penalties and a denial or curtailment of our ability to export our products or provide services. Complying with export control and sanctions laws may be time consuming and may result in the delay or loss of sales opportunities. If we are found to be in violation of U.S. sanctions or export control laws, it could result in substantial fines and penalties for us and for the individuals working for us. Changes in export or import laws or corresponding sanctions may delay the introduction and sale of our products in international markets, or, in some cases, prevent the export or import of our products to certain countries, regions, governments, persons or entities altogether, which could adversely affect our business, financial condition and results of operations.

We are subject to a number of legal requirements, contractual obligations and industry standards regarding security, data protection and privacy and any failure to comply with these requirements, obligations or standards could have an adverse effect on our reputation, business, financial condition and operating results.

Data privacy and information security have become significant issues in the United States and in many other countries where we have employees and operations and where we offer licenses or cloud subscriptions to our offerings. The regulatory framework for privacy and information security issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. The U.S. federal and various state and foreign government bodies and agencies have adopted or are considering adopting laws and regulations limiting, or laws and regulations regarding the collection, distribution, use, disclosure, storage and security of personal information. Laws

Table of Contents

in all 50 states require businesses to provide notice to customers whose personally identifiable information has been disclosed as a result of a data breach. The laws are not consistent, and compliance in the event of a widespread data breach is costly. States are also constantly amending existing laws, requiring attention to frequently changing regulatory environments. For example, in June 2018, California enacted the California Consumer Privacy Act, or CCPA, that, among other things, requires covered companies to provide new disclosures to California consumers, and afford such consumers new abilities to opt-out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that may increase data breach litigation. The CCPA was amended in September 2018 and September 2019 and went into effect on January 1, 2020. While these amendments have helped with understanding certain aspects of the law, we cannot yet predict the impact of the CCPA on our business or operations, but it may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. Moreover, the California Privacy Rights Act ("CPRA") was approved by California voters in the election on November 3, 2020. The CPRA, which becomes effective on January 1, 2023, will significantly modify and expand the CCPA, potentially resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply. Similar comprehensive privacy laws have been enacted in the states of Virginia and Colorado, each of which will become effective in 2023. Given the novelty of the Virginia and Colorado laws and the relative lack of regulatory guidance under the CPRA, it is not fully known how these state privacy laws will be interpreted and enforced.

Internationally, virtually every jurisdiction in which we operate has established its own data security and privacy or data protection legal framework with which we or our MSP partners must comply. Laws and regulations in these jurisdictions apply broadly to the collection, use, storage, disclosure and security of data that is associated with an identifiable or which identifies or may be used to identify or locate an individual. Examples include identifiers such as names, email addresses and, in some jurisdictions, Internet Protocol, or IP, addresses and data that may be associated with identifiers, including items such as marketing records, sales records, financial records, content and correspondence. These laws and regulations often are more restrictive than those in the United States and are rapidly evolving. For example, the E.U. General Data Protection Regulation (the "EU GDPR" or "GDPR") restricts the transfer of personal data outside of the European Economic Area ("EEA"), imposes stringent obligations relating to data protection and information security and authorizes fines up to 4% of global annual revenue or €20 million, whichever is greater, for some types of violations. The GDPR restricts the transfer of personal data outside of the EEA. We transfer personal data outside of the EEA and the U.K. for our own internal business purposes and in order to provide our products and services to our MSP partners. The requirements on such transfers are constantly evolving. In Schrems II (C-311/18), the Court of Justice of the European Union (CJEU) invalidated the E.U.-U.S. Privacy Shield data transfer mechanism, which many companies had relied as an acceptable mechanism for transferring such data from the E.U. to the U.S. Other data transfer mechanisms such as the standard contractual clauses approved by the European Commission, which we use in our business to address certain cross-border data transfers, have faced challenges in European courts (including being called into question in Schrems II), and may be challenged, suspended or invalidated. Such developments may cause us to have to make further expenditures on local infrastructure, change internal business processes, change customer facing products, or otherwise affect or restrict sales and operations. It is further unclear how future decisions related to cross-border transfer restrictions may affect related data transfer mechanisms in other jurisdictions such as the Swiss-US Privacy Shield Framework.

Some countries also are considering or have passed legislation requiring local storage and processing of data, or similar requirements, which could increase the cost and complexity of delivering our services. We may be or become subject to data localization laws mandating that data collected in a foreign country be processed and stored only within that country. If any country in which we have partners were to adopt a data localization law, we could be required to expand our data storage facilities there or build new ones in order to comply. The expenditure, as well as costs of compliance generally, could harm our financial condition.

Because many of the features of our solutions use, store and report on SMB customer data which may contain personal information from SMB customers, any inability to adequately address privacy concerns, to delete stored data at the correct times, or comply with applicable privacy laws, regulations and policies could, even if unfounded, result in liability to us and, damage to our reputation, loss of sales and harm to our business. Furthermore, the costs of compliance with, and other burdens imposed by, such laws, regulations and policies that are applicable to the businesses of our partners may limit the use and adoption of our solutions and reduce overall demand for them. Complying with the GDPR, CCPA or other laws, regulations or other obligations relating to privacy, data protection, data localization or information security may cause us to incur substantial operational costs or require us to modify our data handling practices. Non-compliance could result in proceedings against us by governmental entities or others, could result in substantial fines or other liability, and may otherwise adversely impact our business, reputation, financial condition and operating results. Privacy concerns, whether or not valid, may inhibit market adoption of our solutions.

Some statutory requirements, both in the United States and abroad, include obligations of companies to notify individuals of security breaches involving particular personal information, which could result from breaches experienced by us or our service providers. Even though we may have contractual protections with our service providers, any actual or perceived security breach could impact our reputation, harm our MSP partners’ confidence, hurt our sales and expansion into new markets or cause us to lose existing MSP partners, and could expose us to potential liability or require us to expend significant resources on data security and in responding to any such actual or perceived breach.

Table of Contents

In addition to government regulation, privacy advocates and industry groups may propose self-regulatory standards from time to time. These and other industry standards may legally or contractually apply to us, or we may elect to comply with such standards or to facilitate our MSP partners’ compliance with such standards. Because privacy, data protection and data security are critical competitive factors in our industry, we may make statements on our website, in marketing materials, or in other settings about our data security measures and our compliance with, or our ability to facilitate our MSP partners’ compliance with, these standards. New proposed laws and regulations concerning privacy, data protection and information security are continually evolving. New laws, amendments to or re-interpretations of existing laws and regulations, industry standards, contractual obligations and other obligations may require us to incur additional costs and restrict our business operations. Because the interpretation and application of laws, standards, contractual obligations and other obligations relating to privacy and data protection are complex and sometimes uncertain, it is possible that these laws, standards, contractual obligations and other obligations may be interpreted and applied in a manner that is inconsistent with our data management practices, our privacy, data protection or data security policies or procedures or the features of our offerings. If so, in addition to the possibility of fines, lawsuits and other claims, we could be required to fundamentally change our business activities and practices or modify our offerings, which could have an adverse effect on our business. We may be unable to make such changes and modifications in a commercially reasonable manner or at all, and our ability to develop new offerings and features could be limited. Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations and policies that are applicable to the businesses of our partners may limit the use and adoption of, and reduce the overall demand for, our offerings. Any alleged inability to adequately address privacy, data protection or information security-related concerns, even if unfounded, or to successfully negotiate privacy, data protection or information security-related contractual terms with partners, or to comply with applicable laws, regulations and policies relating to privacy, data protection and information security, could result in additional cost and liability to us, damage our reputation, inhibit sales, slow our sales cycles and adversely affect our business. Privacy and personal information security concerns, whether valid or not valid, may inhibit market adoption of our offerings particularly in certain industries and foreign countries.

We function as a HIPAA “business associate” for certain of our MSP partners and, as such, are subject to strict privacy and data security requirements. If we fail to comply with any of these requirements, we could be subject to significant liability, all of which can adversely affect our business as well as our ability to attract and retain new MSP partners.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations impose specific requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s security standards directly applicable to “business associates.” We function as a business associate for certain of our partners that are HIPAA business associates and service providers, and in that context we are regulated as a business associate for the purposes of HIPAA. If we are unable to comply with our obligations as a HIPAA business associate, we could face substantial civil and even criminal liability. HITECH imposes four tiers of civil monetary penalties and gives state attorneys general authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, many state laws govern the privacy and security of health information in certain circumstances, many of which differ from HIPAA and each other in significant ways and may not have the same effect.

As a business associate, we are required by HIPAA to maintain HIPAA-compliant business associate agreements with our MSP partners for which we, as a service provider, access, maintain, create or transmit individually identifiable health information to render services to our MSP partners. These agreements impose stringent data security and other obligations on us. If we or our subcontractors are unable to meet the requirements of any of these business associate agreements, we could face contractual liability under the applicable business associate agreement as well as possible civil and criminal liability under HIPAA, all of which can have an adverse impact on our business and generate negative publicity, which, in turn, can have an adverse impact on our ability to attract and retain MSP partners.

If we fail to comply with anti-corruption laws, including the FCPA and similar laws associated with our activities outside of the United States, we could be subject to penalties and we could be subject to civil and/or criminal sanctions, and our business could be materially adversely affected.

We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. §201, the U.K. Bribery Act, and possibly other anti-bribery laws in countries in which we conduct activities. We face significant risks if we fail to comply with the FCPA and other anti-corruption laws that prohibit companies and their employees and third-party intermediaries from promising, authorizing, offering or providing, directly or indirectly, improper payments or benefits to foreign government officials, political parties and private-sector recipients for the purpose of obtaining or retaining business, directing business to any person, or securing any advantage. This risk is particularly significant for us given that we rely so heavily on MSP partners, distributors and other third parties to sell our solutions and conduct our business abroad. We or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and we can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize such activities. We have implemented and continue to update an anti-corruption compliance program but cannot assure you that all of our

Table of Contents

employees, agents and MSP partners, as well as those companies to which we outsource certain of our business operations, will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible.

As we continue to expand our business internationally, we will inevitably do more business in countries that are perceived to have heightened levels of public sector corruption. Increased business in countries perceived to have heightened levels of corruption could subject us and our officers and directors to increased scrutiny and increased liability from our business operations. Any violation of the FCPA or other applicable anti-corruption laws by our own employees or our third-party intermediaries, could result in regulatory investigations, whistleblower complaints, adverse media coverage and/or severe criminal or civil sanctions, which could have a materially adverse effect on our reputation, business, operating results and prospects. In addition, responding to any enforcement action may result in a significant diversion of management’s attention and resources and significant defense costs.

Failure to comply with governmental laws and regulations could harm our business.

Our business is subject to regulation by various federal, state, local and foreign governmental agencies, including agencies responsible for monitoring and enforcing employment and labor laws, workplace safety, product safety, environmental laws, consumer protection laws, anti-bribery laws (including the FCPA and the U.K. Anti-Bribery Act), import/export controls, federal securities laws and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than those in the United States. Noncompliance with applicable regulations or requirements could subject us to investigations, sanctions, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, civil and criminal penalties or injunctions. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation resulting from any alleged noncompliance, our business, operating results and financial condition could be materially adversely affected. In addition, responding to any action will likely result in a significant diversion of management’s attention and resources and an increase in professional fees. Enforcement actions, litigation and sanctions could harm our business, operating results and financial condition.

Risks Related to Our Indebtedness

We could incur substantial indebtedness which could adversely affect our business and growth prospects.

On October 23, 2020, Datto, Inc., as borrower (the “Borrower”), and certain direct and indirect wholly-owned subsidiaries of Datto Holding Corp., entered into a credit agreement with the lenders party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent (the "2020 Credit Agreement"). The 2020 Credit Agreement provides for an initial $200.0 million in commitments for revolving credit loans, which amount may be increased or decreased under specific circumstances, with a $40.0 million letter of credit sublimit and a $100.0 million alternative currency sublimit. As of December 31, 2021, there were no borrowings outstanding and $1.9 million of outstanding letters of credit under the 2020 Credit Agreement. However, we could incur significant indebtedness in the future. In addition to revolving credit loans, the 2020 Credit Agreement provides for the ability of the Borrower to request incremental term loan facilities, in a minimum amount of $5.0 million for each facility. In addition, although the financing documents governing our 2020 Credit Agreement contain restrictions on the incurrence of additional indebtedness and liens, these restrictions are subject to a number of important qualifications and exceptions, and the additional indebtedness and liens incurred in compliance with these restrictions could be substantial. Amounts outstanding under our 2020 Credit Agreement may also subject us to mandatory prepayments in certain circumstances and this mandatory prepayment, and future required prepayments, would reduce our cash available for investment in our business.

In addition, the financing documents governing our 2020 Credit Agreement permit us to incur certain additional types of indebtedness, including liabilities that do not constitute indebtedness as defined in the financing documents. We may also consider investments in joint ventures or acquisitions, which may increase our indebtedness. If new debt is added to our currently anticipated indebtedness levels, the related risks that we face could intensify.

Our 2020 Credit Agreement, or any additional indebtedness we may incur, could require us to divert funds identified for other purposes for debt service and impair our liquidity position. If we cannot generate sufficient cash flow from operations to service our debt, we may need to refinance our debt, dispose of assets or issue equity to obtain necessary funds. We do not know whether we would be able to take any of these actions on a timely basis, on terms satisfactory to us or at all. The covenants contained in our 2020 Credit Agreement have important consequences. See “Risk Factors—Risks Related to Our Indebtedness—The terms of the financing documents governing our 2020 Credit Agreement restricts our current and future operations, particularly our ability to respond to changes or to take certain actions."

Furthermore, fluctuations in interest rates can increase borrowing costs and may directly impact the amount of interest we are required to pay and reduce earnings accordingly. In addition, developments in tax policy, such as the disallowance of tax deductions for interest paid on outstanding indebtedness, could have an adverse effect on our liquidity and our business, financial condition and results of operations.

We expect to use cash flow from operations to meet current and future financial obligations, including funding our operations, debt service requirements and capital expenditures. The ability to make these payments depends on our financial and operating performance,

Table of Contents

which is subject to prevailing economic, industry and competitive conditions and to certain financial, business, economic and other factors beyond our control.

We may not be able to generate sufficient cash flow to service all of our indebtedness, and may be forced to take other actions to satisfy our obligations under such indebtedness, which may not be successful.

To the extent we incur indebtedness, our ability to make scheduled payments or to refinance outstanding debt obligations depends on our financial and operating performance, which will be affected by prevailing economic, industry and competitive conditions and by financial, business and other factors beyond our control. We may not be able to maintain a sufficient level of cash flow from operating activities to permit us to pay the principal, premium, if any, and interest on our indebtedness. Any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which would also harm our ability to incur additional indebtedness.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital or seek to restructure or refinance our indebtedness. Any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In the absence of such cash flows and resources, we could face substantial liquidity problems and might be required to sell material assets or operations to attempt to meet our debt service obligations. The financing documents governing our 2020 Credit Agreement restricts our ability to conduct asset sales and/or use the proceeds from asset sales. We may not be able to consummate these asset sales to raise capital or sell assets at prices and on terms that we believe are fair and any proceeds that we do receive may not be adequate to meet any debt service obligations then due. If we cannot meet our debt service obligations, the holders of our indebtedness may accelerate such indebtedness and, to the extent such indebtedness is secured, foreclose on our assets. In such an event, we may not have sufficient assets to repay all of our indebtedness.

The terms of the financing documents governing our 2020 Credit Agreement restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

The financing documents governing our 2020 Credit Agreement contain a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interests, including restrictions on our ability to:

•incur additional indebtedness;

•pay dividends on or make distributions in respect of capital stock or repurchase or redeem capital stock;

•repay, redeem or repurchase certain indebtedness;

•make loans and investments;

•sell or otherwise dispose of assets, including capital stock of restricted subsidiaries;

•incur liens;

•enter into transactions with affiliates;

•enter into agreements restricting the ability of our subsidiaries to pay dividends; and

•consolidate, merge or sell all or substantially all of our assets.

The restrictive covenants in the financing documents governing our 2020 Credit Agreement require us to maintain specified financial ratios and satisfy other financial condition tests to the extent applicable. Our ability to meet those financial ratios and tests can be affected by events beyond our control.

A breach of the covenants or restrictions under the financing documents governing our 2020 Credit Agreement could result in an event of default under such document. Such a default may allow the creditors to accelerate the related debt, to the extent amounts are outstanding, which may result in the acceleration of any other debt to which a cross-acceleration or cross-default provision applies. In the event the holders of our indebtedness accelerate the repayment, we may not have sufficient assets to repay that indebtedness or be able to borrow sufficient funds to refinance it. Even if we are able to obtain new financing, it may not be on commercially reasonable terms or on terms acceptable to us. As a result of these restrictions, we may be:

•limited in how we conduct our business;

•unable to raise additional debt or equity financing to operate during general economic or business downturns; or

Table of Contents

•unable to compete effectively or to take advantage of new business opportunities.

These restrictions, along with restrictions that may be contained in agreements evidencing or governing other future indebtedness, may affect our ability to grow in accordance with our growth strategy.

We may be unable to refinance our indebtedness.

We may need to refinance all or a portion of our indebtedness before maturity. There can be no assurance that we will be able to obtain sufficient funds to enable us to repay or refinance our debt obligations on commercially reasonable terms, or at all.

A lowering or withdrawal of the ratings assigned to our debt securities by rating agencies may increase our future borrowing costs and reduce our access to capital.

Our debt currently has a non-investment grade rating. Any rating assigned could be lowered or withdrawn entirely by a ratings agency if, in that ratings agency’s judgment, future circumstances relating to the basis of the rating, such as adverse changes, so warrant. Any future lowering of our ratings likely would make it more difficult or more expensive for us to obtain debt financing.

Our failure to raise additional capital or generate cash flows necessary to expand our operations and invest in new technologies in the future could reduce our ability to compete successfully and harm our results of operations.

We may need to raise additional funds, and we may not be able to obtain additional debt or equity financing on favorable terms or at all. We may have to amend our 2020 Credit Agreement or issue additional equity to raise additional debt. If we raise additional equity financing, our shareholders may experience significant dilution of their ownership interests. If we engage in debt financing, we may be required to accept terms that constrain our ability to operate the business, restrict our ability to incur additional indebtedness, force us to maintain specified liquidity or other ratios or restrict our ability to pay dividends or make acquisitions. If we need additional capital and cannot raise it on acceptable terms, or at all, we may not be able to, among other things:

•develop and enhance our solutions;

•continue to expand our research and development and sales and marketing organizations;

•hire, train and retain employees;

•respond to competitive pressures or unanticipated working capital requirements; or

•pursue acquisition opportunities.

Risks Related to Ownership of Our Common Stock

Vista controls us, and its interests may conflict with ours or yours in the future.

At December 31, 2021, Vista beneficially owned approximately 69.5% of our common stock, which means that, based on its percentage voting power, Vista controlled the vote of all matters submitted to a vote of our board of directors, or our Board, or shareholders, which enables it to control the election of the members of the Board and all other corporate decisions. In addition, our bylaws provide that Vista has the right to designate the Chair of the Board for so long as Vista beneficially owns at least 30% or more of the voting power of the then outstanding shares of our capital stock then entitled to vote generally in the election of directors. Even when Vista ceases to own shares of our stock representing a majority of the total voting power, for so long as Vista continues to own a significant percentage of our stock, Vista will still be able to significantly influence the composition of our Board, including the right to designate the Chair of our Board, and the approval of actions requiring shareholder approval. Accordingly, for such period of time, Vista will have significant influence with respect to our management, business plans and policies, including the appointment and removal of our officers, decisions on whether to raise future capital and amending our charter and bylaws, which govern the rights attached to our common stock. In particular, for so long as Vista continues to own a significant percentage of our stock, Vista will be able to cause or prevent a change of control of us or a change in the composition of our Board, including the selection of the Chair of our Board, and could preclude any unsolicited acquisition of us. The concentration of ownership could deprive you of an opportunity to receive a premium for your shares of common stock as part of a sale of us and ultimately might affect the market price of our common stock.

In addition, in connection with our IPO, we entered into a Director Nomination Agreement with Vista that provides Vista the right to designate: (i) all of the nominees for election to our Board for so long as Vista beneficially owns 40% or more of the total number of shares of our common stock it owned on the date of the IPO; (ii) a number of directors (rounded up to the nearest whole number) equal to 40% of the total directors for so long as Vista beneficially owns at least 30% and less than 40% of the total number of shares of our common stock it owned on the date of the IPO; (iii) a number of directors (rounded up to the nearest whole number) equal to 30% of the total directors for so long as Vista beneficially owns at least 20% and less than 30% of the total number of shares of our common stock it

Table of Contents

owned on the date of our IPO; (iv) a number of directors (rounded up to the nearest whole number) equal to 20% of the total directors for so long as Vista beneficially owns at least 10% and less than 20% of the total number of shares of our common stock it owned on the date of the IPO; and (v) one director for so long as Vista beneficially owns at least 5% and less than 10% of the total number of shares of our common stock it owned on the date of the IPO, in each case minus the number of designees, if any, Mr. McChord and certain entities affiliated with him are entitled to nominate. The Director Nomination Agreement also provides that Vista may assign such right to a Vista affiliate. The Director Nomination Agreement prohibits us from increasing or decreasing the size of our Board without the prior written consent of Vista.

Vista and its affiliates engage in a broad spectrum of activities, including investments in the information and business services industry generally. In the ordinary course of their business activities, Vista and its affiliates may engage in activities where their interests conflict with our interests or those of our other shareholders, such as investing in or advising businesses that directly or indirectly compete with certain portions of our business or are suppliers or partners of ours. Our certificate of incorporation provides that none of Vista, any of its affiliates or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his director and officer capacities) or its affiliates has any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. Vista also may pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us. In addition, Vista may have an interest in pursuing acquisitions, divestitures and other transactions that, in its judgment, could enhance its investment, even though such transactions might involve risks to you.

We are a “controlled company” within the meaning of the rules of the New York Stock Exchange, and, as a result, we will qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You will not have the same protections as those afforded to stockholders of companies that are subject to such governance requirements.

Vista Funds control a majority of the voting power of our outstanding common stock. As a result, we are a “controlled company” within the meaning of the corporate governance standards of the New York Stock Exchange. Under these rules, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements, including:

•the requirement that a majority of our Board consist of independent directors;

•the requirement that we have a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities;

•the requirement that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

•the requirement for an annual performance evaluation of the nominating and corporate governance and compensation committees.

We intend to continue to utilize these exemptions. As a result, currently we do not have a majority of independent directors on our Board, our Compensation and Nominating Committee does not consist entirely of independent directors and our Compensation and Nominating Committee is not subject to annual performance evaluations. Accordingly, you will not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the New York Stock Exchange.

The requirements of being a public company may strain our resources and distract our management, which could make it difficult to manage our business, particularly after we are no longer an “emerging growth company.”

As a public company, we incur legal, accounting and other expenses that we did not previously incur. In addition, the Company became a large accelerated filer as of December 31, 2021, and no longer qualifies as an emerging growth company ("EGC"). We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the Sarbanes-Oxley Act, the listing requirements of the New York Stock Exchange and other applicable securities rules and regulations. Compliance with these rules and regulations will continue to increase our legal and financial compliance costs, make some activities more difficult, time-consuming and costly and increase demand on our systems and resources. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business, financial condition and results of operations. The Sarbanes-Oxley Act requires, among other things, that we establish and maintain effective internal controls and procedures for financial reporting. Furthermore, the need to establish the corporate infrastructure demanded of a public company may divert our management’s attention from implementing our growth strategy, which could prevent us from improving our business, financial condition and results of operations. We have made, and will continue to make, changes to our internal controls and procedures for financial reporting and accounting systems to meet our reporting obligations as a public company. However, the measures we take may not be sufficient to satisfy our obligations as a public company. These additional obligations could have a material adverse effect on our business, financial condition and results of operations.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws,

Table of Contents

regulations and standards are subject to varying interpretations, in many cases as a result of their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of our management’s time and attention from sales-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies because of ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and could have a material adversely effect on our business, financial condition and results of operations.

Provisions of our corporate governance documents could make an acquisition of us more difficult and may prevent attempts by our shareholders to replace or remove our current management, even if beneficial to our shareholders.

In addition to Vista’s beneficial ownership of 69.5% of our common stock as of December 31, 2021, our certificate of incorporation and bylaws, and the Delaware General Corporation Law, or the DGCL, contain provisions that could make it more difficult for a third-party to acquire us, even if doing so might be beneficial to our shareholders. In certain instances outlined below, these provisions do not take effect until Vista’s beneficial ownership of our common stock drops below a certain percentage. As a result, the anti-takeover effect of these provisions is expected to increase over time as Vista’s beneficial ownership decreases. In each instance, these changes will occur automatically pursuant to the terms of our certificate of incorporation and bylaws and without further action by our Board or shareholders upon Vista’s ownership crossing the applicable thresholds. Among other things, these provisions:

•allow us to authorize the issuance of undesignated preferred stock, the terms of which may be established and the shares of which may be issued without shareholder approval, and which may include supermajority voting, special approval, dividend, or other rights or preferences superior to the rights of shareholders;

•provide for a classified board of directors with staggered three-year terms;

•provide that, at any time when Vista beneficially owns, in the aggregate, less than 40% in voting power of the our stock entitled to vote generally in the election of directors, directors may only be removed for cause, and only by the affirmative vote of holders of at least 66 2/3% in voting power of all the then-outstanding shares of our stock entitled to vote thereon, voting together as a single class;

•these provisions prohibit shareholder action by written consent from and after the date on which Vista beneficially owns, in the aggregate, less than 35% in voting power of our stock entitled to vote generally in the election of directors;

•provide that for as long as Vista beneficially owns, in the aggregate, at least 50% in voting power of our stock entitled to vote generally in the election of directors, any amendment, alteration, rescission or repeal of our bylaws by our shareholders will require the affirmative vote of a majority in voting power of the outstanding shares of our stock and at any time when Vista beneficially owns, in the aggregate, less than 50% in voting power of all outstanding shares of our stock entitled to vote generally in the election of directors, any amendment, alteration, rescission or repeal of our bylaws by our shareholders will require the affirmative vote of the holders of at least 66 2/3% in voting power of all the then-outstanding shares of our stock entitled to vote thereon, voting together as a single class; and

•establish advance notice requirements for nominations for elections to our Board or for proposing matters that can be acted upon by shareholders at shareholder meetings; provided, however, at any time when Vista beneficially owns, in the aggregate, at least 10% in voting power of our stock entitled to vote generally in the election of directors, such advance notice procedure will not apply to it.

Our certificate of incorporation contains a provision that provides us with protections similar to Section 203 of the DGCL, and prevents us from engaging in a business combination with a person (excluding Vista and any of its direct or indirect transferees and any group as to which such persons are a party) who acquires at least 15% of our common stock for a period of three years from the date such person acquired such common stock, unless Board or shareholder approval is obtained prior to the acquisition. These provisions could discourage, delay or prevent a transaction involving a change in control of our Company. These provisions could also discourage proxy contests and make it more difficult for you and other shareholders to elect directors of your choosing and cause us to take other corporate actions you desire, including actions that you may deem advantageous, or negatively affect the trading price of our common stock. In addition, because our Board is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our shareholders to replace current members of our management team.

These and other provisions in our certificate of incorporation, bylaws and Delaware law could make it more difficult for shareholders or potential acquirers to obtain control of our Board or initiate actions that are opposed by our then-current Board, including delay or impede a merger, tender offer or proxy contest involving our company. The existence of these provisions could negatively affect the price of our common stock and limit opportunities for you to realize value in a corporate transaction.

Table of Contents

Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation that may be initiated by our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us.

Pursuant to our certificate of incorporation, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our shareholders, (3) any action asserting a claim against us arising pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws or (4) any other action asserting a claim against us that is governed by the internal affairs doctrine; provided that for the avoidance of doubt, the forum selection provision that identifies the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation, including any “derivative action”, will not apply to suits to enforce a duty or liability created by Securities Act, the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Our certificate of incorporation further provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to the provisions of our certificate of incorporation described above. The forum selection clause in our certificate of incorporation may have the effect of discouraging lawsuits against us or our directors and officers and may limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us.

Our operating results and stock price may be volatile, and the market price of our common stock may drop below the price you pay.

Our quarterly operating results are likely to fluctuate in the future. In addition, securities markets worldwide have experienced, and are likely to continue to experience, significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could subject the market price of our shares to wide price fluctuations regardless of our operating performance. Our operating results and the trading price of our shares may fluctuate in response to various factors, including:

•market conditions in our industry or the broader stock market;

•actual or anticipated fluctuations in our quarterly financial and operating results;

•introduction of new solutions or services by us or our competitors;

•issuance of new or changed securities analysts’ reports or recommendations;

•sales, or anticipated sales, of large blocks of our stock;

•additions or departures of key personnel;

•regulatory or political developments;

•litigation and governmental investigations;

•changing economic conditions;

•investors’ perception of us;

•events beyond our control such as weather and war; and

•any default on our indebtedness.

These and other factors, many of which are beyond our control, may cause our operating results and the market price and demand for our shares to fluctuate substantially. Fluctuations in our quarterly operating results could limit or prevent investors from readily selling their shares and may otherwise negatively affect the market price and liquidity of our shares. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued the stock. If any of our shareholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business, which could significantly harm our results of operations and reputation.

A significant portion of our total outstanding shares may be sold into the market at any time. This could cause the market price of our common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. In connection with our IPO, we entered in a registration rights agreement with Vista, which requires us to affect the registration of Vista's shares in certain circumstances. If Vista exercises its rights under its registration rights agreement it entered into with us to resell a significant amount of its shares of our common stock, we will not receive any proceeds from those offerings. To the extent the Company

Table of Contents

is determined to be a well-known seasoned issuer, the registration and sale of shares held by Vista may take place on an expedited basis. In addition, shares of our common stock that we can issue pursuant to our various equity plans can generally be freely sold in the market upon issuance.

Because we have no current plans to pay regular cash dividends on our common stock for the foreseeable future, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.

We do not anticipate paying any regular cash dividends on our common stock for the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of our Board and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that our Board may deem relevant. In addition, our ability to pay dividends is, and may be, limited by covenants of existing and any future outstanding indebtedness we or our subsidiaries incur, including under our 2020 Credit Agreement. Therefore, any return on investment in our common stock is solely dependent upon the appreciation of the price of our common stock on the open market, which may not occur.

If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our shares or if our results of operations do not meet their expectations, our stock price and trading volume could decline.

The trading market for our shares is influenced by the research and reports that industry or securities analysts publish about us or our business. We do not have any control over these analysts. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover us downgrade our stock, or if our results of operations do not meet their expectations, our stock price could decline.

We may issue shares of preferred stock in the future, which could make it difficult for another company to acquire us or could otherwise adversely affect holders of our common stock, which could depress the price of our common stock.

Our certificate of incorporation authorizes us to issue one or more series of preferred stock. Our Board has the authority to determine the preferences, limitations and relative rights of the shares of preferred stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our shareholders. Our preferred stock could be issued with voting, liquidation, dividend and other rights superior to the rights of our common stock. The potential issuance of preferred stock may delay or prevent a change in control of us, discouraging bids for our common stock at a premium to the market price, and materially adversely affect the market price and the voting and other rights of the holders of our common stock.

ITEM 2. PROPERTIES.

Our corporate headquarters are in Norwalk, Connecticut, where we lease approximately 134 thousand square feet of office space as of December 31, 2021. We also have offices in several other locations within the United States and international offices in Australia, Canada, China, Denmark, Germany, Israel, the Netherlands, Singapore and the United Kingdom.

We lease all of our facilities. We believe that our facilities are adequate for our current needs and anticipate that suitable additional space will be readily available to accommodate any foreseeable expansion of our operations.

ITEM 3. LEGAL PROCEEDINGS.

From time to time, we may become involved in various legal proceedings and claims arising in the ordinary course of business. We do not believe that we are a party to any legal proceeding that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition, or cash flows.

Future litigation may be necessary to defend ourselves and our partners by determining the scope, enforceability and validity of third-party proprietary rights or to establish our proprietary rights. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Overview

Datto is the leading global provider of security and cloud-based software solutions purpose-built for delivery through the managed service provider, or MSP, channel to small and medium businesses, or SMBs. We enable our more than 18,500 MSP partners to manage and grow their businesses serving the SMB information technology, or SMB IT, market. Our platform combines mission-critical cloud-based software, technologies and security solutions that MSPs sell to SMBs, business management software to help MSPs scale their own businesses, and marketing tools, content, training and industry-leading events that cultivate an empowered and highly engaged MSP partner community.

MSPs represent the future of IT management for SMBs. Digital transformation is driving SMB adoption of modern software and technology, while regulatory and data protection requirements and proliferating security threats are increasing the complexity and risk of IT for SMBs. These trends have created an inflection point in SMB outsourcing to MSPs for IT management. MSPs are equipped with the IT resources and expertise SMBs lack, providing a single source to meet all of an SMB’s IT needs. MSPs are trusted to select, procure, implement and manage software and technology stacks that support their SMB customers’ business needs. The number of MSPs continues to grow, with approximately 132,000 MSPs providing this critical function to millions of SMBs worldwide.

We are committed to the success of MSPs. It is the foundation of our strategy and culture. We empower our MSP partner channel, creating enormous sales and support leverage for us to efficiently address the large, but fragmented, SMB IT market. Our MSP-centric platform enables our partners to generate recurring revenue through the sale of our solutions to SMBs and to scale and effectively manage their own businesses. Our relationships are directly with our MSP partners. We are the leading pure-play vendor serving the MSP market, and believe our MSP-centric approach is highly differentiating as it aligns our mutual incentives, creates a motivated and engaged sales channel and reinforces our position as an integral component of our MSP partners’ businesses.

Our cloud-based platform provides Unified Continuity, Networking, Endpoint Management and Business Management software solutions. Our Unified Continuity offerings ensure the ongoing availability and security of mission-critical IT systems for SMBs in both private and public clouds. Datto’s business continuity and disaster recovery, or BCDR, software enables rapid restoration of an SMB’s full IT environment. Datto’s SaaS Protection is a reliable, automated and secure backup and restoration product for data stored on cloud applications such as Microsoft 365 and Google Workspace. Datto Networking constitutes a suite of MSP-centric networking solutions sold through our MSP partners to easily deliver networking as a managed service. These solutions are simple for MSPs to deploy, configure and manage across their SMB customers through a single portal. Our Endpoint Management software allows MSPs to remotely manage, monitor and secure SMB endpoints. Business Management software provides critical operational tools to MSPs for efficient workflow management and delivery of end-to-end managed services. Our platform also includes a host of business development tools, training and content to help MSPs address the challenges of marketing and selling to SMB customers.

During 2021 we launched two new cloud-based solutions - DCMA and SaaS Defense. DCMA is a comprehensive BCDR solution that protects MSPs and their clients’ data in the public cloud in the event of malicious ransomware attacks, security breaches, and vendor outages. SaaS Defense is an advanced threat protection and spam-filtering solution that provides MSPs with patented technology to proactively detect and prevent malicious malware, phishing, and Business Email Compromise ("BEC") attacks that target Microsoft Exchange, OneDrive, SharePoint, and Teams. The product was built on technology obtained in Datto’s acquisition of Israel-based cyber threat detection company BitDam in early 2021.

Our Business Model

Our cloud-based solutions are purpose-built to address the needs of MSPs and to enable the end-to-end delivery of managed services to their SMB customers.

We generate substantially all our revenue from the sale of subscriptions to our cloud-based solutions and recognize revenue ratably over the subscription term. These contracts typically begin with a 1-year or 3-year term and auto-renew on a monthly or annual basis thereafter. For certain offerings, we enable our ongoing subscription services with an up-front sale of equipment or professional services, for which we recognize revenue at the time of delivery and performance. The majority of our partners pay on a monthly basis, regardless of term length, with some opting to make quarterly, annual or multi-year prepayments.

Unified Continuity subscriptions are priced based on service tier, which is determined by data storage capacity and data retention period for our BCDR products, or by number of Microsoft 365 or Google Workspace employee accounts at the SMB domains that our MSP partners protect and data retention period for SaaS Protection+ offerings. Networking subscriptions are priced based on the volume and type of networking devices ordered. Endpoint Management subscriptions are priced per endpoint device at the SMB for our RMM software. Business Management subscriptions are priced based on the number of employees at an MSP that are able to utilize our PSA product.

We employ a highly efficient land-and-expand sales strategy facilitated by offering products that are reliable, easy to adopt and that drive recurring revenue growth and margin efficiency for our MSP partners. We sell our solutions to MSPs primarily through our sales team, leveraging the reach of our MSP partners and providing them with self-service options to upgrade service tiers, add volume and purchase additional solutions. Our MSP partners often significantly increase usage from their initial purchase and expand their usage to other products on our platform. We also provide access to business development tools and content to help MSPs address the challenges of marketing and selling to SMB customers. We grow alongside our MSP partners as they deploy our solutions across their existing SMB customers, add new customers and upgrade service tiers.

As of December 31, 2021, our ARR was $658.4 million and our revenue for the year ended December 31, 2021 was $618.7 million, of which approximately 93% was recurring subscription revenue. For the year ended December 31, 2021, our net income was $51.4 million and our Adjusted EBITDA was $175.4 million. As of December 31, 2020, our ARR was $542.8 million and our revenue for the year ended December 31, 2020, was $518.8 million, of which approximately 94% was recurring subscription revenue. For the year ended December 31, 2020, our net income was $22.5 million and our Adjusted EBITDA was $150.5 million. Refer to our discussion of ARR in Key Performance Metrics and Adjusted EBITDA in Non-GAAP Financial Measures.

Trends and Uncertainties

Impact of COVID-19

While we have not incurred significant disruptions from the COVID-19 pandemic, there remains uncertainty relating to the ultimate impact of the pandemic on our business because of numerous global factors, including but not limited to, the severity of the disease, the duration of the pandemic, the reoccurrence or emergence of variants of the virus, the effectiveness and speed of vaccinations, actions taken by government authorities, the impact on our customers and suppliers, supply chain constraints, labor shortages, inflationary pressure and other factors. Specifically, we may experience impacts from customers deferring purchasing and activation decisions, reducing expenses and requesting extended payment terms or relief from payments.

Our condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in our condensed consolidated financial statements include, but are not limited to, establishing allowances for doubtful accounts, assessing the recoverability of prepaid assets, including trade shows and other marketing events impacted by the pandemic, determining useful lives for finite-lived assets, assessing the recoverability of long-lived assets, determining the fair value of assets acquired and liabilities assumed in business combinations, accounting for income taxes and related valuation allowances against deferred tax assets, valuing stock-based awards, recognizing revenue and the estimate for sales returns and upgrades, determining the amortization period for capitalized commissions and assessing the accounting treatment for commitments and contingencies. Management evaluates these estimates and assumptions on an ongoing basis and makes estimates based on historical experience and various other considerations that are believed to be reasonable. Actual results may differ from those estimates, including as a result of the COVID-19 pandemic. We will continue to evaluate the nature and extent of the impact of the pandemic on our business and our consolidated results of operations and financial condition.

Macro-Economic or Industry Trends

We believe favorable industry trends will contribute to the growth of our business, including: increased adoption by SMBs of digital and cloud-based technologies; increasing complexity in IT, which impacts the ability of SMBs to evaluate, select and implement an optimal

Table of Contents

IT environment; increased exposure and vulnerability of SMBs to security and regulatory risk, including as a result of cyberattacks; lack of SMB sophistication to meet the expanding challenges of IT management; and the costs of downtime or data loss that can be meaningful and continue to expand.

The customer base of our partners continues to expand, as evidenced by the anticipated 13.4% increase in available market reported by Frost & Sullivan during 2021. The demand for MSPs grows as i) more SMBs embrace digital transformation, including a shift to the cloud, ii) the move to remote work continues, and iii) educational organizations and governmental agencies begin to use MSPs to provide IT services.

Key Factors Affecting Our Performance

Addition of New MSPs

Our ability to attract new partners will depend on a number of factors, including the effectiveness of our pricing and products, offerings of our competitors, the effectiveness of our marketing efforts, and the growth of the MSP market. We believe there is substantial opportunity to increase our penetration among MSPs. We intend to drive new partner acquisition by continuing to invest significantly in sales and marketing to identify and engage prospective partners and to extend the awareness of our brand as a trusted partner to the MSP community. We believe our singular dedication to the MSP channel and our solutions that are purpose-built to meet the needs of MSPs differentiates us in the marketplace. We intend to continue to grow the number of sales representatives to qualify and close new partner opportunities. In addition, we intend to continue investing in marketing programs, events and content to drive brand awareness, generate leads and cultivate the broader MSP ecosystem. As of December 31, 2021, we had approximately 18,500 MSP partners, a net increase of approximately 1,500 since December 31, 2020.

Sales Expansion Within Our Existing Partner Base

Our ability to expand sales within our existing partner base will depend on a number of factors, including their satisfaction with our solutions and support, competition, the effectiveness of the business development tools we provide to our partners and the ability of our partners to grow their sales. Our large base of partners represents a significant opportunity for further sales expansion. Once an MSP has become our partner, we aim to grow alongside them as they increase penetration of our solutions across their existing SMB partner base, attract additional SMB customers, upgrade service tiers and adopt additional Datto solutions. We have a strong track record of growth from our existing base as evidenced by our history of partner cohort expansion and our dollar-based net retention rate, which was 116% and 111% as of December 31, 2021 and 2020, respectively. We intend to continue to invest in MSP self-service procurement tools to further enable a frictionless purchasing process, grow the number of sales representatives to facilitate increased partner adoption of our solutions and invest in enabling our partners’ sales teams through our marketing automation platform, programs, content, training and certifications for MSPs. As of December 31, 2021, over 1,400 of our MSP partners contributed ARR of $100,000 or more, up from over 1,100 as of December 31, 2020. See “Key Performance Metrics” below for a definition of dollar-based net retention rate and ARR.

Innovation and Introduction of New Platform Solutions

Our continued growth is dependent upon our ability to sustain innovation in order to maintain a competitive advantage. We recognize that the pace of technological innovation is accelerating and that we need to continue to innovate to maintain our product differentiation. We continually invest in improving our existing solutions and creating new mission-critical solutions to anticipate the evolving IT demands of MSPs and their SMB customers. In addition, we evaluate strategic investments in businesses and technologies to drive product and market expansion. For example, in January 2022 we acquired Infocyte, a threat detection and response company, extending Datto’s security capabilities that protect, detect, and respond to cyber threats found within endpoints and cloud environments; in March 2021, we acquired BitDam Ltd., an Israel-based cyber threat detection company ("BitDam"), which served as the foundation of SaaS Defense; and in July 2020 we acquired Gluh Pty. Ltd., and Keystone Software Holdings Pty Ltd., two affiliated Australia-based companies which offer a real-time quoting platform that enables MSPs to simplify the procurement of IT products and services for their end customers, which was the foundation of Datto Commerce.

Expansion of Our International Footprint

Our international growth in any region will depend on our ability to effectively implement our business processes and go-to-market strategy, our ability to adapt to market or cultural differences, the competitive landscape, the maturity and growth trajectory of the MSP market and our brand awareness and perception. We believe there is significant opportunity to expand internationally. For 2021 and 2020, our international revenue was approximately 30% and 27%, respectively, of our total revenue, reflecting our investment in international markets. We intend to continue to make significant investments in international markets, particularly in EMEA and APAC. This may include investing in additional sales and marketing personnel, localizing product offerings and marketing content, and adding

Table of Contents

new data-center or office locations. Although these investments may adversely affect our operating results in the near term, we believe they will contribute to our long-term growth.

Key Performance Metrics

In addition to our GAAP financial information, we review a number of operating and financial metrics, including the following key metrics, to evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions.

MSP Partners

The number of MSP partners represents the number of MSPs with active subscriptions as of the end of the period. We use this number to assess our ability to attract and retain MSP partners and thereby grow our business. As of December 31, 2021, we had over 18,500 MSP partners, a net increase of approximately 1,500 since December 31, 2020. Net changes in the number of our MSP partners are a result of the total new partners added during a period, largely based on our sales and marketing efforts, and the churn or reduction of existing partners during the period, which can be affected by the broader economic environment and factors such as the effects of COVID-19 on our partners' SMB end customers. As a result of our land-and-expand model, our revenue growth is driven principally by additional revenue from existing MSP partners. We view new MSP partner additions as a leading indicator of the health of the business, but the additions do not immediately drive material revenue growth in our reported results of operations.

Annual Run-Rate Revenue

We define annual run-rate revenue, or ARR, as the annualized value of all subscription agreements as of the end of a period. We calculate ARR by multiplying the monthly run-rate revenue for the last month of a period by 12. Monthly run-rate revenue is calculated by aggregating monthly subscription values during the final month of the reporting period from both long-term and month-to-month subscriptions. ARR only includes the annualized value of subscription contracts and excludes any one-time revenue for devices or professional services. ARR mitigates fluctuations resulting from seasonality and contract term. ARR does not have any standardized meaning and is therefore unlikely to be comparable to similarly titled measures presented by other companies. ARR should be viewed independently of revenue and deferred revenue and is not intended to be combined with or to replace either of those items. ARR is not a forecast and the active contracts at the date used in calculating ARR may or may not be extended or renewed by our MSP partners.

The table below sets forth our ARR as of December 31, 2021, 2020 and 2019:


	As of December 31,
(in millions)	2021		2020		2019
ARR	$	658.4	$	542.8	$	474.8

ARR includes run-rate revenue values from month-to-month subscription contracts. For the years ended December 31, 2021, and 2020 approximately 40% and 42%, respectively, of our ARR was derived from month-to-month contracts. The decrease in percent of ARR from month-to-month contracts reflects our improvement in securing more long-term contracts in the current year as the COVID-19 pandemic slowed the addition of long-term contracts during 2020.

Our dollar-based gross retention rate as of December 31, 2021, 2020 and 2019, was approximately 89%, 88% and 88%, respectively. Our dollar-based gross retention rate reflects ARR losses from subscription cancellations, reductions in service levels or seat counts and non-renewals, and does not reflect any ARR expansion. We calculate our dollar-based gross retention rate as of the period end by starting with the ARR from the last day of the period one year prior, or Prior Period ARR. We then deduct from the Prior Period ARR any (i) ARR attrition from MSP partners who are no longer partners as of the last day of the period, and (ii) ARR compression from MSP partners whose subscriptions are at a lower value as of the last day of the period, or Remaining ARR. We then divide the Remaining ARR by the Prior Period ARR to arrive at our dollar-based gross retention rate, which is the percentage of ARR from all MSP partners as of the year prior that is not lost to partner churn or subscription compression. Given the meaningful percentage of our subscription revenue derived from month-to-month contracts, the approximately 89% dollar-based gross retention rate demonstrates that a large majority of our MSP partners continue to renew their subscription contracts, whether on a month-to-month or longer term basis. Based on our experience, we do not believe month-to-month contracts experience significantly higher attrition than longer-term subscription contracts.

Dollar-Based Net Retention Rate

To evaluate the efficacy of our land-and-expand business model, we examine the rate at which our partners increase their subscriptions for our solutions which result in changes to ARR. Our dollar-based net retention rate measures our ability to increase ARR

Table of Contents

across our existing partner base through expanded use of our platform, offset by MSP partners whose subscription contracts with us are not renewed or are renewed at a lower amount.

We calculate our dollar-based net retention rate as of the end of a reporting period as a quotient of the following:

•Denominator: ARR as of the last day of the prior year comparative reporting period.

•Numerator: ARR as of the last day of the current reporting period from partners with associated ARR as of the last day of the prior year comparative reporting period.

The quotient obtained from this calculation is our dollar-based net retention rate. We believe our ability to grow alongside our MSP partners as they deploy our solutions to more SMBs, and to cross-sell additional solutions, will continue to support our high dollar-based net retention rate.

As of December 31, 2021, 2020 and 2019, our dollar-based net retention rate was 116%, 111% and 119%, respectively.

Because existing MSP partners drive the vast majority of our revenue growth in any given year, we believe our revenue growth is strongly correlated to our dollar-based net retention rate.

Components of Results of Operations

Revenue

We generate revenue primarily from fees received for subscriptions to our products and services, and also from the sale of BCDR and Networking devices and professional services associated with our Business Management offerings.

Subscription. We derive revenue primarily from security and cloud-based software solutions sold on a recurring subscription basis. Subscription revenue is recognized ratably over the subscription term after all revenue recognition criteria have been met. We generally invoice subscription agreements monthly over the subscription period. Subscription revenue for our Unified Continuity, Networking and Endpoint Management solutions grows as the end-customers, managed by our MSP partners, add new subscription products, upgrade the service tier of their existing subscription products, increase the usage of their subscription products or add more end-user devices managed by their MSP. Revenue from our Business Management solutions increases with the addition of employees of our MSP partners who require seat licenses and as MSPs purchase Datto Commerce subscriptions.

Device. Our device revenue is derived from the sale of devices in conjunction with subscription solutions. Device revenue includes the sale of BCDR and Networking devices which enable us to deliver our BCDR and Networking services to our MSP partners under a recurring subscription model. Revenue from devices in our Unified Continuity solution primarily consists of the sale of our proprietary data storage devices. Revenue from devices in our Networking solution primarily consists of the sale of wireless access points, switches and edge routers. We recognize revenue at the point in time when control of the device has transferred to the MSP or upon activation of the related subscription. Revenue from devices does not contribute significantly to overall revenue related to our Unified Continuity solutions.

Professional services and other. We derive revenue from professional services associated with our Business Management offerings. These implementation and consulting services include configuration, database merging and data migration. Our professional services are generally priced on a time and materials basis and invoiced monthly, with revenue recognized as the services are performed, and we frequently discount our services to drive adoption of our business management offerings.

Cost of revenue

Subscription. Subscription cost of revenue consists of costs directly related to our subscription services, including personnel costs associated with operating our Datto Cloud infrastructure and customer support operations, hosting and data center related costs, third-party software licenses and allocated facilities and overhead costs associated with delivering these services.

Device. Device cost of revenue consists of hardware, manufacturing, shipping and logistics, personnel costs and allocated facilities and overhead costs associated with the purchase, production and delivery of our devices. Our BCDR products rely on a mix of off-the-shelf hardware and custom designed hardware. Our Networking devices generally consist of off-the-shelf hardware, although some of our devices feature a unique industrial design.

Professional services and other. Professional services and other cost of revenue consists primarily of personnel costs and allocated facilities and overhead costs associated with delivering implementation and consulting services. Our professional services

Table of Contents

implementations aim to ensure higher software utilization and positive customer satisfaction, in order to drive greater upsell opportunity and lower churn over time.

Depreciation and amortization. Depreciation and amortization cost of revenue consists of depreciation of our Datto Cloud infrastructure and amortization of our acquired technology intangible assets.

Gross profit and gross margin

Gross profit, or revenue less cost of revenue, has been, and will continue to be, affected by various factors, including revenue fluctuations, the mix of revenue, the timing and amount of investments to expand our Datto Cloud infrastructure and launch new solutions, the use of third-party software licenses and stock-based compensation expense.

Operating expenses

Our operating expenses consist of sales and marketing, research and development and general and administrative expenses as well as depreciation, amortization of internally developed software and amortization of acquired intangible assets. Personnel costs are the most significant component of operating expenses and consist of salaries, benefits, bonuses, sales commissions, payroll taxes and stock-based compensation expense. Other significant components of operating expenses include professional fees, third-party software subscription costs, facilities and overhead costs, events and travel, marketing and promotion costs, payment processing fees and bad debt expense.

Sales and marketing

Sales and marketing expenses consist primarily of personnel costs, costs for events and travel, costs of marketing and promotional activities, payment processing fees and allocated facilities and overhead costs. Sales and marketing expenses may fluctuate as a percentage of our revenue from period to period because of the timing and extent of marketing activities, trade shows, and events including DattoCon and MSP Technology Days, as well as the timing of amortization of sales commissions and stock-based compensation expense.

Research and development

Research and development expenses consist primarily of personnel costs, third-party professional fees and allocated facilities and overhead costs. Research and development expense may fluctuate as a percentage of our revenue from period to period because of the timing and extent of our investments in research and development activities, as well as the timing of stock-based compensation expense.

General and administrative

General and administrative expenses consist primarily of personnel costs across the corporate functions of executive, finance, human resources, information technology, internal operations and legal, as well as third-party professional fees, bad debt expense, travel and costs for facilities. Following the completion of our initial public offering ("IPO") we began incurring additional general and administrative expenses as a result of operating as a publicly listed company, including increased expenses for insurance, costs to comply with the rules and regulations applicable to companies listed on a national securities exchange, costs related to compliance and reporting obligations pursuant to the rules and regulations of the SEC, expenses related to investor relations, professional services fees, particularly for auditing, and increased stock-based compensation expense.

Depreciation and amortization

Depreciation and amortization expenses in operating expenses consist of amortization of tradenames and partner relationship intangibles, depreciation of other property and equipment such as leasehold improvements, furniture and fixtures, and computer equipment, and amortization of internally developed software.

Other expense

Interest expense

Interest expense consists of interest payments on outstanding borrowings under our credit facilities, as well as commitment fees under our credit facilities and the amortization of debt issuance costs. In conjunction with our IPO in October 2020, we repaid all amounts outstanding under our 2019 Credit Agreement. In October 2020, Datto, Inc. and certain direct and indirect wholly-owned subsidiaries of Datto, entered into the 2020 Credit Agreement with the lenders party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent, which provides a $200.0 million revolving credit facility. As of December 31, 2021, no amounts had been drawn under the 2020 Credit Agreement. See “Liquidity and Capital Resources—Credit Facilities” for additional details.

Table of Contents

Other (income) expense

Other (income) expense primarily consists of the net exchange (gains) or losses on foreign currency transactions and (gains) or losses on the disposal of assets.

Loss on extinguishment of debt

Loss on extinguishment of debt reflects the loss incurred in conjunction with the termination of our credit facilities in both 2020 and 2019. See “Liquidity and Capital Resources—Credit Facilities” for additional details.

(Benefit from) provision for income tax

(Benefit from) provision for income tax consists primarily of income taxes related to U.S. federal and state income taxes and income taxes in foreign jurisdictions in which we conduct business.

Stock-Based Compensation

The functional role of the holder determines the financial statement line item within which stock-based compensation expense is recorded. Stock-based compensation expense for awards which contained only a time-based vesting condition was recorded in all periods presented. Stock-based compensation expense for awards which contained both a time-based and a performance-based vesting condition, which was the closing of an IPO, commenced during the fourth quarter of 2020 as a result of our IPO. Additionally, in 2021 the Company issued restricted stock units with performance-based vesting conditions in relation to the acquisition of BitDam, for which stock-based compensation expense was recorded based on the expected achievement of the performance targets.

Subscription

Subscription revenue increased $92.0 million, or 19.0%, for 2021 compared to 2020, including a benefit from favorable foreign exchange rates of approximately 2%. The increase in subscription revenue was primarily driven by increased sales of our Unified Continuity and Endpoint Management cloud-based offerings, as well as increased sales of our Business Management and Networking cloud-based offerings. Recurring subscription revenue accounted for 93% of total revenue for 2021 compared to 94% for 2020.

Total cost of revenue	$	176,348	$	150,204	$	26,144	17.4	%

Subscription

Subscription cost of revenue increased $5.7 million, or 6.7%, for 2021 compared to 2020. The increase was primarily driven by additional costs to support the growth of our subscription offerings, including increased personnel costs and higher service costs to support the growth of our Datto Cloud, including costs related to the launch of our new SaaS Defense solution. We continued to realize increased efficiencies, as subscription cost of revenue as a percentage of subscription revenue declined from 17.4% in 2020 to 15.6% in 2021. Subscription cost of revenue reflects stock-based compensation expense of $4.3 million and $4.1 million for 2021 and 2020, respectively. In 2020, we recorded restructuring costs of $0.5 million related to our reduction in workforce in subscription cost of revenue.

Device

Device cost of revenue increased $9.8 million, or 26.1%, for 2021 compared to 2020, driven primarily by the 25.3% increase in device revenue and to a lesser extent the impact of increased shipping costs. Device cost of revenue reflects stock-based compensation expense of $0.2 million for each of 2021 and 2020.

Professional services and other

Professional services and other cost of revenue decreased $0.2 million, or 3.0% for 2021 compared to 2020. Professional services and other cost of revenue reflects stock-based compensation expense of $0.2 million and $0.4 million during 2021 and 2020, respectively. In 2020, we recorded restructuring costs of $0.1 million related to our reduction in workforce in professional services and other cost of revenue.

Depreciation and amortization

Depreciation and amortization related to cost of revenue increased $10.8 million for 2021 compared to 2020. The increase reflects higher depreciation expense in 2021 associated with the continued capital expenditures for our Datto Cloud infrastructure to support the growth in subscriptions and the increase in amortization of acquired intangible assets in 2021 as a result of recent acquisitions. Depreciation expense was $23.3 million and $16.9 million in 2021 and 2020, respectively, and amortization of intangible assets was $9.5 million and $5.0 million in 2021 and 2020, respectively.

Our gross profit increased $73.7 million, or 20.0%, and our gross margin increased by 45 basis points for 2021 as compared to 2020, driven by the increase in subscription gross profit and gross margin. The increase was partially offset by higher depreciation and amortization expense, primarily as a result of our investment in our Datto Cloud infrastructure and the amortization of acquired intangible assets, and increased Device negative gross profit margin in 2021 as compared to 2020. Subscription gross margin increased 179 basis points for 2021 as compared to 2020 as a result of our revenue growth out pacing the increased costs to provide our Unified Continuity solutions, although we did incur additional costs in 2021 to launch our new SaaS Defense solution. Cost of revenue reflects stock-based compensation expense of $4.7 million for each of 2021 and 2020. In 2020, we recorded restructuring costs of $0.6 million related to our reduction in workforce in cost of revenue, including $0.5 million in subscription cost of revenue and $0.1 million in professional services and other cost of revenue.

Sales and marketing

Sales and marketing expense increased $23.5 million, or 20.3%, for 2021 compared to 2020, driven by increased personnel costs to support the growth in our business, including higher commission expense and increased stock-based compensation expense of $2.9 million, partially offset by lower restructuring costs. Marketing and promotional costs also increased during 2021 as compared to 2020, as we increased our marketing efforts in support of our launch of DCMA and SaaS Defense, as well as marketing efforts in support of our other solutions. Sales and marketing expense included $9.5 million and $6.6 million of stock-based compensation expense for 2021 and 2020, respectively. In 2020, we recorded $1.9 million of restructuring costs related to our reduction in workforce in sales and marketing expense.

Research and development

Research and development expense increased $29.0 million, or 36.7%, for 2021 compared to 2020, primarily driven by increases in personnel costs, including increased stock-based compensation expense of $9.8 million and our continued investment in innovation and information security. Research and development expense included $23.4 million and $13.6 million of stock-based compensation expense

Table of Contents

for 2021 and 2020, respectively. In 2020, we recorded $0.9 million of restructuring costs related to our reduction in workforce in research and development expense.

General and administrative

General and administrative expense increased $20.8 million, or 24.3%, for 2021 compared to 2020, driven primarily by increased personnel costs, including increased stock-based compensation expense of $2.8 million, increased expenses related to being a publicly listed company, higher expenses to support increased levels of hiring, and transaction related and other expense. Partially offsetting these increases were a $5.8 million reduction in bad debt expense primarily as a result of improved collections activity. General and administrative expense included $11.3 million and $8.5 million of stock-based compensation expense for 2021 and 2020, respectively, and $5.2 million and $3.1 million of transaction related and other expense for 2021 and 2020, respectively. In 2020, we recorded $0.4 million of restructuring costs related to our reduction in workforce in general and administrative expense.

Depreciation and amortization

Depreciation and amortization expense related to operating expenses decreased $0.8 million, or 2.8% for 2021 compared to 2020. Amortization of intangible assets was $17.7 million in each of 2021 and 2020, and depreciation expense and amortization of internally developed software was $8.8 million and $9.5 million in 2021 and 2020, respectively.

Other Expenses

Interest expense

Interest expense decreased $24.9 million for 2021 compared to 2020 as a result of the repayment of all outstanding debt with the proceeds from our IPO in the fourth quarter of 2020. In conjunction with the IPO, we terminated our 2019 Credit Agreement and entered into the 2020 Credit Agreement. As of December 31, 2021 no amounts were drawn under the 2020 Credit Agreement and we had no outstanding debt.

Loss on extinguishment of debt

A loss on extinguishment of debt of $8.5 million was recorded in 2020 as a result of our debt refinancing which took place in conjunction with our IPO.

Other (income) expense, net

Other (income) expense, net primarily relates to the impact of net exchange gains or losses on foreign currency balances, principally related to intercompany balances denominated in foreign currencies.

Provision for income taxes

We recorded a provision for income taxes of $9.9 million and $8.1 million for 2021 and 2020, respectively. The effective tax rate for 2021 and 2020 was 16.2% and 26.4%, respectively. The effective tax rate in 2021 reflects the favorable impact of an amendment to our 2018 and 2019 federal tax returns as a result of clarification of certain tax guidance, a change in tax law in the state of Connecticut resulting in the ability to utilize additional research and development credits generated in prior years which impacted our valuation allowance, and research and development credits generated in the current year, partially offset by the impact of state income taxes and permanent differences for non-deductible expenses. The effective tax rate for 2020 reflects the unfavorable impact of permanent differences related to stock-based compensation for certain employees and the impact of state income taxes, partially offset by the favorable impact of research and development credits and foreign operations.

Non-GAAP Financial Measures

In addition to our results determined in accordance with accounting principle generally accepted in the United States ("GAAP"), we believe the non-GAAP measures of Non-GAAP Gross Profit, Non-GAAP Income from Operations, Non-GAAP Net Income and Adjusted EBITDA are useful in evaluating our operating performance. We believe that non-GAAP financial information may be helpful to investors because it provides consistency and comparability with past financial performance and assists in comparisons with other companies, some of which use similar non-GAAP information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only and should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly titled non-GAAP measures used by other companies. A reconciliation is provided below for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures.

Non-GAAP Gross Profit

Non-GAAP Gross Profit is a supplemental measure of operating performance that is not prepared in accordance with GAAP and that does not represent, and should not be considered as, an alternative to gross profit, as determined in accordance with GAAP. We define Non-GAAP Gross Profit as gross profit, adjusted for amortization of acquired intangible assets, stock-based compensation expense, and restructuring expense. We use Non-GAAP Gross Profit to understand and evaluate our core operating performance and trends and to develop short-term and long-term operating plans. We believe Non-GAAP Gross Profit is a useful measure to us and to our investors to assist in evaluating our core operating performance because it provides consistency and direct comparability with our past financial performance and between fiscal periods, as the metric eliminates the effects of variability of stock-based compensation expense and amortization of acquired technology intangible assets, which are non-cash expenses that may fluctuate for reasons unrelated to overall operating performance, as well as restructuring expense, which is infrequent in nature. While the amortization expense of acquired technology intangible assets is excluded from Non-GAAP Gross Profit, the revenue related to acquired technology intangible assets is reflected in Non-GAAP Gross Profit as these assets contribute to our revenue generation. Non-GAAP Gross Profit has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Because of these limitations, Non-GAAP Gross Profit should not be considered as a replacement for gross profit, as determined by GAAP, or as a measure of our profitability. We compensate for these limitations by relying primarily on our GAAP results and using non-GAAP measures only for supplemental purposes. Our presentation of Non-GAAP Gross Profit should not be construed to imply that our future results will be unaffected by the types of items excluded from the calculation of Non-GAAP Gross Profit. Non-GAAP Gross Profit is not a presentation made in accordance with GAAP and the use of the term may vary from other companies.

A reconciliation of Non-GAAP Gross Profit to gross profit, the most directly comparable GAAP measure, is as follows:

Restructuring expense(1)	—		601		—
Non-GAAP Gross Profit	$	456,455	$	378,918	$	306,243

(1)Restructuring expense primarily relates to severance costs incurred in connection with a reduction in workforce undertaken in Q2 2020 to align our cost structure to expectations of potentially reduced revenue resulting from the COVID-19 pandemic. Approximately $0.6 of restructuring expense was recorded within cost of revenue for 2020.

Non-GAAP Income from Operations

Non-GAAP Income from Operations is a supplemental measure of operating performance that is not prepared in accordance with GAAP and that does not represent, and should not be considered as, an alternative to income from operations as determined in accordance with GAAP. We define Non-GAAP Income from Operations as income from operations, adjusted for amortization of acquired intangible assets, stock-based compensation, restructuring expense and transaction related and other expense. We use Non-GAAP Income from Operations to understand and evaluate our core operating performance and trends and to develop short-term and long-term operating plans. We believe that Non-GAAP Income from Operations facilitates comparison of our operating performance on a consistent basis between periods, and when viewed in combination with our results prepared in accordance with GAAP, helps provide a broader picture of factors and trends affecting our results of operations. While the amortization expense of acquired technology, partner

relationships and tradenames is excluded from Non-GAAP Income from Operations, the revenue related to acquired technology, partner relationships and tradenames is reflected in Non-GAAP Income from Operations as these assets contribute to our revenue generation. Non-GAAP Income from Operations has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Because of these limitations, Non-GAAP Income from Operations should not be considered as a replacement for operating income, as determined by GAAP, or as a measure of our profitability. We compensate for these limitations by relying primarily on our GAAP results and using non-GAAP measures only for supplemental purposes.

Approximately $3.2 million and $0.6 million of restructuring expense was recorded within operating expenses and cost of revenue, respectively, for 2020.

(2)Transaction related and other expense consists of acquisition related costs, litigation related charges or benefits and other unusual charges, as well as costs incurred during the year ended December 31, 2020 to support our public company readiness.

Non-GAAP Net Income

Non-GAAP Net Income is a supplemental measure of operating performance that is not prepared in accordance with GAAP and that does not represent, and should not be considered as, an alternative to net income (loss) as determined in accordance with GAAP. We define Non-GAAP Net Income as net income (loss) before income taxes, adjusted for loss on extinguishment of debt, amortization of acquired intangible assets, stock-based compensation expense, restructuring expense, and transaction related and other expense. The Company utilizes a normalized non-GAAP tax rate to provide better consistency across the reporting periods by eliminating the effects of non-recurring and period-specific items, which can vary in size and frequency, and which are not necessarily indicative of the Company’s long-term operations. The normalized non-GAAP tax rate applied to each period presented was 25%. We use Non-GAAP Net Income to understand and evaluate our core operating performance and trends and to develop short-term and long-term operating plans. We believe that Non-GAAP Net Income facilitates comparison of our operating performance on a consistent basis between periods, and when viewed in combination with our results prepared in accordance with GAAP, helps provide a broader picture of factors and trends affecting our results of operations. While the amortization expense of acquired technology, partner relationships and tradenames is excluded from Non-GAAP Net Income, the revenue related to acquired technology, partner relationships and tradenames is reflected in Non-GAAP Net Income as these assets contribute to our revenue generation. Non-GAAP Net Income has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Because of these limitations, Non-GAAP Net Income should not be considered as a replacement for net income (loss), as determined by GAAP, or as a measure of our profitability. We compensate for these limitations by relying primarily on our GAAP results and using non-GAAP measures only for supplemental purposes. Our presentation of Non-GAAP Net Income should not be construed to imply that our future results will be unaffected by the types of items excluded from the calculation of Non-GAAP Net Income. Non-GAAP Net Income is not a presentation made in accordance with GAAP and the use of the term may vary from other companies.

(3)The normalized non-GAAP tax rate applied to each period presented was 25%. The Company may adjust its non-GAAP tax rate as additional information becomes available or events occur which may materially affect this rate, including impacts from the rapidly evolving global tax environment, significant changes in our geographic mix, merger and acquisition activity, or changes in our business outlook.

Adjusted EBITDA

Adjusted EBITDA is a supplemental measure of operating performance monitored by management that is not defined under GAAP and that does not represent, and should not be considered as, an alternative to net income (loss), as determined by GAAP. We define Adjusted EBITDA as net income (loss) adjusted for interest and other expense, net, loss on extinguishment of debt, depreciation and amortization, (provision for) benefit from income taxes, stock-based compensation expense, restructuring expense and transaction related and other expense. We use Adjusted EBITDA to understand and evaluate our core operating performance and trends and to develop short-term and long-term operating plans.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including net income (loss) and our other GAAP results. Our presentation of Adjusted EBITDA should not be construed to imply that our future results will be unaffected by the types of items excluded from the calculation of Adjusted EBITDA. Adjusted EBITDA is not a presentation made in accordance with GAAP and the use of the term may vary from other companies.

Liquidity and Capital Resources

General

As of December 31, 2021, our cash, including restricted cash, totaled $222.7 million, as compared to $170.4 million as of December 31, 2020. In addition, as of each of December 31, 2021 and 2020, we had no debt outstanding and $198.1 million of capacity under our 2020 Revolving Credit Agreement (defined below). We believe our existing cash and cash equivalents, cash provided by our ongoing operations and borrowing capacity under our 2020 Revolving Credit Facility will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months.

Historically, as we invested in our organization and infrastructure to meet increasing demand for our products and services and to drive our rapid growth, we have financed our operations primarily through cash provided by our ongoing operations, debt financing and more recently our IPO. During 2020, in response to the spread of COVID-19 and its impacts on the world economy, we undertook various measures to improve our liquidity position and better match our cost structure to our revenue and cash generation activities, and we continue to benefit from these measures. In addition, the COVID-19 pandemic continues to cause a reduction of marketing, event and travel costs, as events are held virtually and travel is limited. In the future we will continue to invest in our organization and infrastructure and expect to resume hosting our world-class partner events in-person when it is safe to do so, as we grow and innovate along with our MSP partners.

Our future capital requirements will depend on several factors, including the need to invest in our Datto Cloud infrastructure to support our subscription revenue growth, the timing of cash receipts and payments, the timing and extent of spending to support research and development, the pace of expansion of sales and marketing activities, including in international markets, the level of investment in back-office infrastructure, the cost to operate as a publicly listed company and the amount of our outstanding indebtedness. In the future, we may also enter into arrangements to acquire or invest in complementary businesses, services and technologies, including intellectual property rights.

We may be required to seek additional equity or debt financing to meet our future capital requirements. In the event additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital or generate cash flows necessary to fund the expansion of our operations and invest in new technologies, this could reduce our ability to compete successfully and harm our results of operations.

Credit Facilities

On October 23, 2020, we closed our IPO which generated net proceeds, after deducting the underwriters discount, of $641.6 million. Shortly after closing the IPO, the Company utilized the IPO proceeds and $38.4 million of available cash to repay the outstanding balances under the 2019 Credit Agreement of $590.2 million, pay $1.6 million of related accrued interest, and pay $1.2 million in debt issuance costs for the 2020 Credit Agreement.

On October 23, 2020, Datto, Inc., as borrower (the “Borrower”), Merritt Holdco, Inc., Autotask Superior Holding, Inc., Backupify, Inc., Autotask Corporation, Open Mesh, Inc. and SoonR, Inc., each a direct or indirect wholly-owned subsidiary of Datto Holding Corp., entered into the 2020 Credit Agreement with the lenders party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent. The 2020 Credit Agreement is guaranteed by Merritt Holdco, Inc., Autotask Superior Holding, Inc., Backupify, Inc., Open Mesh, Inc., Autotask Corporation, and SoonR, Inc. (the “Guarantors,” and, together with the Borrower, the “Loan Parties”) and is supported by a security interest in substantially all of the Loan Parties’ personal property and assets, subject to customary exceptions.

The 2020 Credit Agreement provides for an initial $200.0 million in commitments for revolving credit loans, which may be increased or decreased under specific circumstances, with a $40.0 million letter of credit sublimit and a $100 million alternative currency sublimit (the “2020 Revolving Credit Facility”). In addition, the 2020 Credit Agreement provides for the ability of the Borrower to request incremental term loan facilities. Borrowings pursuant to the 2020 Credit Agreement may be used for working capital and other general corporate purposes, including for acquisitions permitted under the 2020 Credit Agreement.

Borrowings under the 2020 Credit Agreement are scheduled to mature on October 23, 2025. The 2020 Credit Agreement contains certain customary events of default, which include failure to make payments when due thereunder, the material inaccuracy of

Table of Contents

representations or warranties, failure to observe or perform certain covenants, cross-defaults, bankruptcy and insolvency-related events, certain judgments, certain ERISA-related events, or a Change in Control (as defined in the 2020 Credit Agreement).

The 2020 Credit Agreement contains certain customary representations and warranties and affirmative and negative covenants, including certain restrictions on the ability of the Loan Parties and their Restricted Subsidiaries (as defined in the 2020 Credit Agreement) to incur any additional indebtedness or guarantee indebtedness of others, to create liens on properties or assets, and to enter into certain asset and stock-based transactions. In addition, under the terms of the 2020 Credit Agreement, the Borrower's First Lien Net Leverage Ratio shall not be more than 4.00 to 1.00.

The interest rates applicable to the revolving borrowings under the 2020 Credit Agreement, are, at the Borrower’s option, either (i) a base rate, equal to the greater of (a) the Prime Rate, (b) the Federal Funds Effective Rate plus 0.5% or (c) the Adjusted LIBO Rate for a one month Interest Period (each term as defined in the 2020 Credit Agreement) plus 1%, or (ii) the Adjusted LIBO Rate equal to the LIBO Rate for the applicable Interest Period, plus in the case of each of clauses (i) and (ii), the Applicable Rate (as defined in the 2020 Credit Agreement). The Applicable Rate (i) for base rate loans range from 0.25% to 1.0% per annum and (ii) for LIBO Rate loans range from 1.25% to 2.0% per annum, in each case, based on the Senior Secured Net Leverage Ratio (as defined in the 2020 Credit Agreement). The Borrower will pay a commitment fee during the term of the 2020 Credit Agreement ranging from 0.20% to 0.35% per annum of the average daily undrawn portion of the revolving commitments based on the Senior Secured Net Leverage Ratio (as defined in the 2020 Credit Agreement).

Any borrowings under the 2020 Credit Agreement may be repaid, in whole or in part, at any time and from time to time without premium or penalty other than customary breakage costs, and any amounts repaid may be reborrowed. No mandatory prepayments will be required other than when borrowings and letter of credit usage exceed the aggregate commitment of all lenders.

The 2020 Revolving Credit Facility was undrawn as of each of December 31, 2021 and December 31, 2020 with the exception of $1.9 million of outstanding letters of credit as of each date.

Cash Flows

The following table presents a summary of our consolidated cash flows from operating, investing, and financing activities for the periods indicated.


	Year Ended December 31,
	2021		2020		2019
	(in thousands)
Net cash provided by operating activities	$	125,366	$	108,698	$	11,235

Net cash provided by financing activities	$	21,725	$	75,679	$	18,505

Operating Activities

For 2021, net cash provided by operating activities was $125.4 million, which resulted from net income of $51.4 million, adjusted for non-cash charges of $119.8 million and net cash outflow of $45.8 million from changes in operating assets and liabilities. Non-cash charges primarily consisted of depreciation and amortization expenses of $59.2 million, stock-based compensation expense of $48.9 million, non-cash operating lease expense of $7.3 million and an increase in deferred income taxes of $4.9 million. The net cash outflow from changes in operating assets and liabilities was primarily driven by an increase in inventory of $21.2 million, as we have increased purchases to guard against possible supply chain disruptions resulting from the COVID-19 pandemic, an increase in other assets of $19.6 million primarily driven by an increase in deferred contract acquisition costs, as well as an increase in prepaid expenses and other current assets of $11.5 million, primarily driven by increased contract assets, net and inventory deposits, partially offset by an increase in accounts payable, accrued expenses and other of $8.4 million primarily resulting from the timing of payments. In 2021, we paid $2.9 million of social security tax which we elected to defer in 2020 as provided in the CARES Act.

For 2020, net cash provided by operating activities was $108.7 million, which resulted from net income of $22.5 million, adjusted for non-cash charges of $106.8 million and net cash outflow of $20.6 million from changes in operating assets and liabilities. Non-cash charges primarily consisted of depreciation and amortization expenses of $49.1 million, stock-based compensation expense of $33.5 million, loss on extinguishment of debt of $8.5 million and an increase in deferred income taxes of $7.8 million. The net cash outflow from changes in operating assets and liabilities was primarily driven by an increase in other assets of $13.0 million primarily driven by an increase in deferred contract acquisition costs, as well as an increase in prepaid expenses and other current assets of $7.5 million, primarily driven by the payment of insurance as a result of becoming a public company. We also elected to defer payment of our obligation for social security tax for the remainder of 2020 as provided in the CARES Act, resulting in a reduction in cash outflows of $5.8 million during 2020.

Investing Activities

For 2021, net cash used in investing activities was $92.7 million, including capital expenditures of $47.2 million, primarily related to our investment in servers for our Datto Cloud infrastructure to support our overall subscription growth as well as investments in the development of our cloud-based platforms to serve our partners. We also purchased computer equipment to support our increased workforce. In addition, we used $45.5 million, net of cash acquired, for the acquisition of BitDam.

For 2020, net cash used in investing activities was $44.8 million, primarily resulting from investment in servers for our Datto Cloud infrastructure to support our overall subscription growth as well as investments in the development of our cloud-based platforms to serve our partners. In addition, we incurred expenses for leasehold improvements and furniture and fixtures to expand and update certain offices and purchased computer equipment to support our workforce and global expansion. In July 2020, we acquired two affiliated Australian entities, Gluh Pty Ltd and Keystone Software Holdings Pty Ltd, which offer a tool for MSPs to quote, sell and procure IT goods and services. The amount paid was approximately $4.4 million, reflecting the purchase price of $4.0 million and certain closing adjustments.

Financing Activities

For 2021, net cash provided by financing activities was $21.7 million, primarily reflecting proceeds from the exercise of stock options of $22.5 million.

For 2020, net cash provided by financing activities was $75.7 million, primarily reflecting proceeds from our IPO, net of the underwriting discount, of $641.6 million, proceeds in the first quarter of 2020 of $32.1 million from our revolving credit facility, as we drew down the balance given the uncertainty in the global economy as a result of the COVID-19 pandemic, and proceeds from the

Table of Contents

exercise of stock options of $3.2 million. These cash proceeds were partially offset by debt repayments of $594.7 million as a result of our IPO, including $590.2 million to repay all outstanding balances under our 2019 Credit Agreement, payment of IPO costs of $5.3 million, and payment of debt issuance costs of $1.2 million for our 2020 Credit Agreement.

Indemnification Agreements

In the ordinary course of business, we enter into agreements of varying scope and terms pursuant to which we agree to indemnify MSP partners, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, services to be provided by us or from intellectual property infringement claims made by third parties. No demands have been made upon us to provide indemnification under such agreements and there are no claims that we are aware of that could have a material effect on our consolidated balance sheet, consolidated statement of operations and comprehensive loss or consolidated statement of cash flows. In addition, we have entered into indemnification agreements with our directors and certain officers and employees that require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees.

Critical Accounting Estimates

Our discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements included in this Annual Report on Form 10-K. The preparation of our consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may differ from those estimates.

Our critical accounting estimates are those that materially affect our consolidated financial statements and involve difficult, subjective or complex judgments by management. A thorough understanding of these critical accounting estimates is essential when reviewing our consolidated financial statements.

Revenue Recognition

We recognize revenue in accordance with the Financial Accounting Standards Board's Accounting Standards Codification Topic 606. We generate revenue from fees received for subscriptions, support and related services, and from the sale of devices. We recognize revenue related to contracts with partners when we transfer promised goods or services to partners in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This is determined by following a five-step process which includes (1) identifying the contract with a partner, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price and (5) recognizing revenue when or as we satisfy a performance obligation.

We identify performance obligations in a contract based on the goods and services that will be transferred to the partner that are identifiable or distinct from other promises in the contract. If not considered distinct, the promised goods or services are combined with other goods or services and accounted for as a combined performance obligation. Determining the distinct performance obligations in a contract requires judgment. Our performance obligations primarily include subscription services, including warranties, unspecified upgrades or enhancements to our hosted SaaS offerings, delivery of devices and training. We believe that our technical support, warranties and unspecified upgrades or enhancements performance obligations each have the same pattern of transfer to the partner and are therefore accounted for as a single distinct performance obligation.

We allocate the transaction price of the contract to each distinct performance obligation on a relative standalone selling price basis. Estimating standalone selling prices for our performance obligations requires judgment and is based on multiple factors including, but not limited to, observable cost data, industry margin studies, historical selling prices, internal pricing policies and pricing practices in different regions and through different sales channels and internal cost structure. We review the standalone selling price for our performance obligations periodically and update them, if needed, to ensure that the methodology utilized reflects our current pricing practices.

Contract Acquisition Costs

We capitalize commission expenses that are incremental to obtaining customer contracts, using a portfolio approach. These contract acquisition costs are deferred and recorded in other assets on our consolidated balance sheets. We make judgments in determining the amount of costs to be expensed in the period, including amounts which are expensed as incurred, which is the approach if the expected period of benefit is less than one year, and amounts which are capitalized and expensed over future periods, which is the approach if the expected period of benefit is beyond one year. The period of benefit often extends beyond the contract term, as we only pay a commission on the initial contract term and not upon renewal of the contract. We have determined that the expected period of benefit is

Table of Contents

five years based on evaluation of a number of factors, including customer attrition rates, weighted average useful lives of our partner relationship and developed technology intangible assets, and market factors, including the overall competitive environment and the technology life utilized by competitors. Contract acquisition costs which are capitalized are amortized as a component of sales and marketing expense in our consolidated statements of operations.

Income Taxes

Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases, as well as net operating loss and tax credit carryforwards. Deferred tax assets represent amounts available to reduce income taxes payable in future periods. Deferred tax assets are evaluated for future realization and reduced by a valuation allowance to the extent we believe they will not be realized. We consider many factors when assessing the likelihood of future realization of deferred tax assets, including recent cumulative loss experience and expectations of future earnings, the carry-forward periods available for tax reporting purposes, and other relevant factors.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits are recognized from such positions based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Interest and penalties related to unrecognized tax benefits are recognized within income tax expense.

Business Combinations

We account for business combinations by assigning the total consideration transferred to the fair value of acquired assets and liabilities. We record goodwill based on the excess of the purchase price for acquisitions over the fair value of the net assets acquired. Determining the fair value of assets and liabilities assumed requires management to make significant estimates and assumptions. In determining the fair value of an acquired intangible asset we generally based our valuation on available historical information, future expectations, market data, and management's reasonable assumptions. While we use our best estimates and assumptions as part of the purchase price allocation, our estimates are inherently uncertain and subject to refinement.

Recent Accounting Pronouncements

For a description of our recently adopted accounting pronouncements and accounting pronouncements issued but not yet adopted, see Note 2. Significant Accounting Policies to our consolidated financial statements in this Annual Report on Form 10-K.

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market risk represents the risk of loss that may impact our financial position because of adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of exposure resulting from potential changes in inflation or interest rates. We do not hold financial instruments for trading purposes.

Foreign Currency Exchange Risk

The functional currencies of our foreign subsidiaries are generally the respective local currencies. Most of our sales and operating expenses are denominated in the currencies of the countries in which our operations are located, which are primarily in the United States, United Kingdom and Europe, although we do have certain arrangements in which we invoice in a non-functional currency, based upon the location of the Partner. Our consolidated results of operations and cash flows are, therefore, subject to fluctuations resulting from changes in foreign currency exchange rates and may be adversely affected in the future because of changes in foreign exchange rates. To date, we have not entered into any hedging arrangements with respect to foreign currency risk or other derivative financial instruments. During the year ended December 31, 2021, a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have had a material impact on our consolidated financial statements.

Interest Rate Risk

At December 31, 2021, we had no outstanding borrowings under the 2020 Credit Agreement. To the extent we incur borrowings, our primary interest rate risk is from changes in interest rates based on the Prime Rate, the Federal Funds Effective Rate or LIBO Rate (and the LIBOR Successor Rate). Interest rate risk is sensitive to many factors, including U.S. monetary and tax policies, U.S. and international economic factors and other factors beyond our control.

Inflation Risk

During 2021, the Company experienced inflation in the costs of certain products and services. We expect to be able to largely offset certain higher costs through increased operational efficiencies and potentially certain price increases. If our costs, in particular

personnel and data centers costs, were to become subject to substantial inflationary pressures our inability or failure to offset such increases with other savings or adjust our prices could harm our business and operating results.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Datto Holding Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Datto Holding Corp. (the “Company”) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), changes in stockholders' equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 23, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Adoption of ASU 2016-02

As discussed in Note 2 to the consolidated financial statements, the Company changed its method for accounting for leases in fiscal year 2021 due to the adoption of ASU 2016-02, Leases (Topic 842).

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which they relate.


						Revenue from Contracts with Customers
Description of the matter						For the year-ended December 31, 2021, the Company recognized revenue of $618.7 million. As described in Note 2 to the consolidated financial statements, the Company derives its revenue from subscription fees from customers for the right to access software hosted by the Company in the cloud, and from the sale of devices. The Company’s revenue recognition process involves several applications responsible for the initiation, processing, and recording of transactions from the Company’s various sales channels, and the calculation of revenue in accordance with the Company’s accounting policy. Auditing the Company's accounting for revenue from contracts with customers was especially challenging and complex due to the high volume of individually-low-monetary-value transactions, dependency on the effective design and operation of multiple IT applications, and the completeness and accuracy of the data used in allocating contract consideration to the performance obligations which is done manually outside of effective IT applications.

Table of Contents



How we addressed the matter in our audit						To test the revenue recognized from contracts with customers, we performed substantive audit procedures that included, among others, testing on a sample basis the completeness and accuracy of the underlying data within the Company’s billing systems by reconciling contract information between multiple data sources. In addition, we performed data analytics by extracting data from the underlying IT applications to evaluate the completeness and accuracy of the calculations used to allocate consideration to each performance obligation, traced a sample of sales transactions to source data, and tested a sample of cash to billings reconciliations.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2018.

Notes to Consolidated Financial Statements

1. Business

Description of Business

Datto Holding Corp. ("Datto Holding") provides security and cloud-based software solutions purpose-built for delivery through the managed service provider (“MSP”) channel to small and medium businesses (“SMB”). Unless the context otherwise indicates or requires, references to "Datto", “we,” “us,” “our” and “the Company” shall refer to Datto Holding and its wholly-owned subsidiaries as a consolidated entity.

The Company’s platform enables its MSP partners to serve the SMB information technology market and includes mission critical cloud-based software and technologies that MSPs sell to SMBs, business management software to help MSPs scale their own businesses, and marketing tools, content, training and industry-leading events that cultivate an empowered and highly engaged MSP partner community. The Company typically has no contractual relationship with the SMBs and considers its MSP partners to be the customers. By selling through the MSP channel, the Company is able to cost-effectively scale the reach of the Company’s solutions and support the global requirements of SMBs without a direct-to-SMB sales and support model.

Datto Holding owns 100% of Merritt Holdco, Inc. (“Merritt Holdco”), which owns 100% of Datto, Inc., the Company’s primary operating company. Datto Holding has no operations or significant assets or liabilities other than its investment in Merritt Holdco. Accordingly, Datto Holding is dependent upon distributions from Merritt Holdco to fund any activity, including the payment of dividends. All obligations under Datto’s 2020 Credit Agreement are guaranteed by Merritt Holdco.

Initial Public Offering

On October 23, 2020, the Company completed an initial public offering (“IPO”) of its common stock. As part of the IPO, the Company issued and sold 22,000,000 shares of its common stock at a public offering price of $27.00 per share. The Company received proceeds of approximately $558.0 million from the IPO, after deducting the underwriting discounts. In addition, on November 3, 2020, the underwriters exercised their option in full to purchase 3,300,000 additional shares of common stock at a price of $27.00 per share, resulting in proceeds of approximately $83.6 million, after deducting the underwriting discounts.

The Company utilized the IPO proceeds to repay the outstanding principal balances under the 2019 Credit Agreement of $590.2 million, $5.3 million of IPO offering costs, and $1.2 million in debt issuance costs for the 2020 Credit Agreement, as defined in Note 12. Debt. Upon entering the 2020 Credit Agreement, the 2019 Credit Agreement was terminated, and the Company wrote-off approximately $8.5 million of unamortized debt issuance costs and original issue discount related to the 2019 Credit Agreement.

As of December 31, 2021 funds controlled by Vista Equity Partners ("Vista") owned approximately 69.5% of the Company’s outstanding common stock, excluding treasury shares. As a result, the Company is a “controlled company” under New York Stock Exchange ("NYSE") corporate governance rules. See Note 18. Related Party Transactions for information regarding transactions with Vista.

Emerging Growth Company Status

On June 30, 2021, the last day of the Company’s second fiscal quarter in 2021, the market value of the Company’s common equity held by non-affiliates exceeded $700 million. Accordingly, the Company became a large accelerated filer as of December 31, 2021, and no longer qualifies as an emerging growth company ("EGC"). As a result, the Company no longer has the ability to take advantage of the extended transition period to comply with new or revised accounting standards. As discussed in Note 2. Significant Accounting Policies below, certain accounting standards were adopted in the fourth quarter of 2021 with an effective date of January 1, 2021, in accordance with the standards. However, since the Company was an EGC for periods prior to January 1, 2021, the Company’s consolidated financial statements for fiscal years prior to 2021 may not be comparable to the financial statements of issuers who were required to comply with the effective dates for new or revised accounting standards prior to January 1, 2021.

Table of Contents

2. Significant Accounting Policies

Basis of Presentation

The consolidated financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of Datto and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Segment Information

Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the CODM. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one reporting unit, within a single operating segment, and therefore is a single reportable segment. During 2021, 2020, and 2019, the Company did not have a material balance of long-lived assets located outside of the United States.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to revenue recognition, contract balances, contract acquisition costs, allowance for expected credit losses, reserves for inventory obsolescence, useful lives and recoverability of long-lived assets, income taxes, stock-based compensation, the Company's incremental borrowing rate and contingencies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, including the uncertainty surrounding rapidly changing market and economic conditions from the COVID-19 pandemic. Actual results could materially differ from these estimates.

Foreign Currency Translation

The Company’s reporting currency is the U.S. Dollar. The functional currency of the Company's foreign subsidiaries is generally the local currency. Assets and liabilities are translated into U.S. Dollars at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenue, expenses, gains and losses are translated using average exchange rates for the period. Resulting foreign currency translation adjustments are recorded directly within accumulated other comprehensive income (loss), a separate component of stockholders’ equity.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in other (income) expense, net in the accompanying consolidated statements of operations. The Company recognized other expense of $0.5 million for 2021, other income of $3.1 million for 2020 and other expense of $0.8 million for 2019 for foreign currency transaction activity.

Cash, Cash Equivalents and Restricted Cash

Cash is stated at fair value. As of December 31, 2021 and 2020 the U.S. Dollar value of cash and restricted cash denominated in foreign currencies was $36.3 million and $28.1 million, respectively, and these balances were comprised principally of Euro, Canadian Dollars, Australian Dollars, and British Pounds.

Cash equivalents consist of short-term, highly liquid investments with an original maturity of three months or earlier. The Company did not hold any cash equivalents as of December 31, 2021 or 2020.

Restricted cash primarily includes amounts held by banks as security deposits related to lease arrangements for office space.

Accounts Receivable Net of Allowance for Expected Credit Losses

Trade accounts receivable are recorded at the invoiced amount. Accounts receivable are presented net of an estimated allowance for expected credit losses. The Company maintains an allowance for expected credit losses as a reduction of trade accounts receivable’s amortized cost basis to present the net amount expected to be collected. The Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASC 326”) as of January 1, 2021, as described below. Prior to the adoption of ASC 326 the Company's allowance was based upon an analysis of past credit history and the current financial condition of the Company's customers, as well as the consideration of expected trends based upon characteristics of the accounts and general economic conditions, such as the impact of COVID-19. Under the application of ASC 326, the Company’s historical credit loss experience provides the basis for the estimation of expected credit losses. In developing its expected credit loss

Table of Contents

estimate, the Company evaluated the appropriate grouping of financial assets based upon its evaluation of risk characteristics, including consideration of the industry and geography of its customers and the Datto solutions sold. Account balances are written off against the allowance for expected credit losses after all means of collection have been exhausted and the potential for recovery is considered remote.

The following table summarizes the activity of the allowance (in thousands):


	Amount
Balance as of December 31, 2018	$	2,080
Provision for expected credit losses	6,634
Net deductions and other	(1,620)
Balance as of December 31, 2019	$	7,094
Provision for expected credit losses	6,217
Net deductions and other	(7,826)

Provision for expected credit losses	367
Net deductions and other	(3,934)
Balance as of December 31, 2021	$	1,918

Unbilled accounts receivable are included in the accounts receivable balances and represent revenue earned, but the amount is not contractually billable as of the balance sheet date. The unbilled accounts receivable balance is principally invoiced within the following month. As of December 31, 2021 and 2020, unbilled accounts receivable, net was $1.6 million, and $3.0 million, respectively.

Concentrations of Business and Credit Risk

As of and for the years ended December 31, 2021, 2020 and 2019, no single customer represented over 10% of the Company's revenues or accounts receivable.

The Company is exposed to concentrations of credit risk primarily through its cash balances held by financial institutions. The Company deposits its cash with multiple financial institutions and the amount on deposit at each institution typically exceeds federally insured limits.

Inventory

Inventory consists of components, work in progress and finished goods, and are stated at the lower of cost (first-in, first-out method) or net realizable value. Components consist of hard drives, solid state memory and chassis, which are used in assembling the Company's devices. The Company also utilizes components in the assembly of servers which are deployed in its data centers, which are capitalized when deployed in the data center as property and equipment on the Company's consolidated balance sheets. The Company assesses the valuation of inventory and adjusts the value for estimated excess and obsolete inventory based upon estimates of future demand and market conditions, as well as damaged or otherwise impaired goods.

Debt Issuance Costs

The Company capitalizes costs incurred to obtain debt financing if certain criteria are met. Unamortized debt issuance costs are presented as a direct reduction of the carrying value of the debt or as other assets when no debt balances are outstanding. The capitalized costs are amortized over the term of the loan agreement using the effective interest method, as a component of interest expense in the consolidated statements of operations.

Contract Acquisition Costs

The Company capitalizes commission expenses paid to internal sales personnel, which are incremental to obtaining customer contracts, using a portfolio approach. These contract acquisition costs are deferred and recorded in other assets on the Company's consolidated balance sheets. The Company makes judgments in determining the amount of costs to be expensed in the period, including amounts which are expensed as incurred if the period of benefit is less than one year, and amounts which are capitalized and expensed over future periods if the expected period of benefit is beyond one year. The period of benefit often extends beyond the contract term, as the Company only pays a commission on the initial contract term and not upon renewal of the contract. Contract acquisition costs are allocated to each performance obligation within the contract and amortized on a straight-line basis over the expected period of benefit of the related performance obligation. Contract acquisition cost amortization is recorded as a component of sales and marketing expense in the Company's consolidated statements of operations.

Table of Contents

The Company has determined that the expected period of benefit is five years based on an evaluation of a number of factors, including customer attrition rates, weighted average useful lives of the Company's partner relationships and developed technology intangible assets, and market factors, including the overall competitive environment and the technology life utilized by competitors. The Company periodically reviews the capitalized contract acquisition costs for impairment. As of December 31, 2021 and 2020, the Company has not identified any potential indicators of impairment.

Property and Equipment, Net

Property and equipment are recorded at cost and presented net of accumulated depreciation and amortization. Significant additions or improvements extending the useful life of an asset are capitalized, while repairs and maintenance costs are expensed as incurred. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the term of the lease or the useful life of the assets.

Software Development Costs

Internally developed software includes software developed to meet our internal needs to provide cloud-based subscription offerings to our partners and other software we develop to meet our specific operational needs. These capitalized costs for internal-use software consist of internal compensation related costs and third-party direct costs incurred during the application development stage and are amortized using the straight-line method over the useful life, which is generally two to five years, commencing when the asset is substantially ready for use. Amortization of capitalized internal-use software development costs are expensed as a component of depreciation and amortization within operating expenses in our consolidated statements of operations.

The costs to develop software that is embedded on our devices and thus marketed externally have not been capitalized as we believe our current software development process is essentially completed concurrent with the establishment of technological feasibility. As such, all related software development costs are expensed as incurred and included in research and development expense in our consolidated statements of operations.

Capitalized Implementation Costs

Costs to implement cloud computing arrangements that are service contracts are capitalized consistent with the accounting guidance for internal-use software. Capitalized costs include third-party and internal compensation related direct costs. During 2021, 2020 and 2019, the Company capitalized $3.2 million, $3.1 million, and $4.4 million, respectively, of costs associated with cloud computing arrangements related to the implementation and configuration of systems to manage certain financial operations, business processes and customer interactions. Capitalized costs are amortized using the straight-line method over the expected period of benefit, including periods which are reasonably expected to be renewed, as a component of cost of revenue or operating expenses, depending on the Company's utilization of the cloud computing arrangement. Capitalized costs, net of accumulated amortization, are included in prepaid expenses and other current assets and other assets based on the expected period of benefit. Costs capitalized are included as a component of net cash provided by (used in) operating activities in the consolidated statements of cash flows.

Business Combinations

The Company includes the results of operations of the businesses it acquires as of the respective dates of acquisition. The Company allocates the fair value of the purchase price of acquisitions to the tangible assets acquired, liabilities assumed, and intangible assets acquired, based on their estimated fair values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill. Additional information existing as of the acquisition date but unknown to the Company may become known during the remainder of the measurement period, not to exceed 12 months from the acquisition date, which may result in changes to the amounts and allocations recorded.

Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets

Goodwill is evaluated for impairment on an annual basis in the fourth quarter of our fiscal year, and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company has elected to first assess qualitative factors to determine whether it is more likely than not the fair value of its single reporting unit is less than the carrying amount, including goodwill. If the Company determines it is more likely than not the fair value of its single reporting unit is less than the carrying amount, then the quantitative impairment test is performed. Under the quantitative impairment test, if the carrying amount of the Company's single reporting unit exceeds its fair value, the Company recognizes an impairment loss in an amount equal to the excess, although the impairment loss is limited to the total amount of goodwill.

The Company evaluates events and changes in circumstances that could indicate carrying amounts of intangible assets and other long-lived assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of

Table of Contents

these assets by determining whether or not the carrying amount will be recovered through expected future undiscounted cash flows. If the total of the expected future undiscounted cash flows is less than the carrying amount of an asset, the Company records an impairment loss for the amount by which the carrying amount of the asset exceeds the fair value of the asset.

The Company did not recognize any impairment losses on its goodwill, intangible assets or other long-lived assets during 2021, 2020 and 2019.

Stock-Based Compensation

The fair value of stock-based awards is measured at the grant date and is recognized as expense, net of actual forfeitures. The Company has issued stock-based awards with a time-based vesting condition, for which stock-based compensation expense is typically recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. The Company has on occasion issued awards which contained both a time-based and a performance-based vesting condition, specifically, the closing of an IPO ("IPO Contingent Options"). Since the closing on an IPO was not deemed probable until consummated, stock-based compensation expense for the IPO Contingent Options commenced during the fourth quarter of 2020 as a result of the Company's IPO, and is being recognized using the accelerated attribution method. In 2021 the Company also issued restricted stock units with performance-based vesting conditions in connection with the acquisition of BitDam, for which stock-based compensation expense is being recorded based on the expected achievement of the performance targets.

The fair value of stock options is determined using the Black-Scholes option pricing model. The fair value of restricted stock units ("RSUs") is determined based on the closing price of the Company's common stock on the NYSE as reported on the last trading day prior to the grant date. The Black-Scholes option pricing model requires the input of several variables and subjective assumptions, including the fair value of the Company's underlying common stock, the risk-free interest rate, the expected term of the award, the expected stock price volatility, and expected dividends.

Fair Value of the Company's Underlying Common Stock: Prior to the Company's IPO, the fair value of the Company’s shares of common stock underlying equity awards was determined by the Board of Directors ( the "Board") with input from management and contemporaneous third-party valuations, as there was no public market for the Company's common stock. The Board determined the fair value of the common stock by considering a number of objective and subjective factors including: the valuation of comparable companies, the Company’s operating and financial performance, the likelihood of achieving a liquidity event, such as an IPO or sale of the Company given prevailing market conditions, and the general and industry specific economic outlook. After the IPO, the fair value of the Company’s shares of common stock underlying equity awards is based on the closing price of the Company's common stock on the NYSE as reported on the last trading day prior to the grant date.

Risk-Free Interest Rate: The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the stock option’s expected term.

Expected Term of the Award: The expected term represents the period the stock-based awards are expected to be outstanding. The Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term because of the limited period of time that a public market for its common stock has been available. As a result, for stock options with only a time-based vesting condition, the Company used the simplified method to calculate the estimate of the expected term of the award. Under the simplified method, the expected term is equal to the average of the stock-based award’s weighted average vesting period and its contractual term. For the IPO Contingent Options, the Company estimated the expected term based on the date the performance condition was satisfied, which was the Company's IPO.

Expected Stock Price Volatility: Since the Company does not have a significant trading history of its common stock, the expected volatility is derived from the average historical stock volatilities of several unrelated public companies within its industry that management considers to be comparable to the Company's business, over a period equivalent to the expected term of the awards. The Company intends to continue to consistently apply this process to estimate the expected volatility until sufficient historical information regarding the volatility of the share price of its common stock becomes available.

Dividend Yield: The expected dividend yield is zero as the Company has never declared or paid cash dividends and has no current plans to do so in the foreseeable future.

Revenue Recognition

The Company recognizes revenue according to the following principles as defined in ASC 606:

•Identify the contract with a customer

•Identify the performance obligations in the contract

Table of Contents

•Determine the transaction price

•Allocate the transaction price to the performance obligations in the contract

•Recognize revenue when or as the Company satisfies a performance obligation

Sales tax, value-added tax and goods and services tax collected from customers and remitted to governmental authorities is not included in revenue.

Subscription revenue

These services represent an MSP’s right to access software hosted by the Company in the cloud, as well as supporting services such as when-and-if-available updates and technical support, and are categorized as follows:

•Unified continuity, networking and endpoint management solutions include an array of business continuity and disaster recovery (“BCDR”) capabilities, including full image-based backup, virtualization, cloud replication and restoration of a customer’s full environment, SaaS application backup and restoration, network monitoring and management, and remote monitoring and management ("RMM"). These services typically include private cloud storage, technical support and online training and are sold under a recurring revenue model.

•Business management solutions integrate a broad range of mission critical business systems, including professional services automation (“PSA”), customer relationship management, service desk, contract management, scheduling, project management, billing and reporting, quoting and procurement.

The Company's subscription arrangements do not provide customers with the right to take possession of the software supporting the platform and, as a result, are accounted for as service arrangements. Revenue is generally recognized ratably over the contract term, although revenue for certain subscription services are based upon monthly usage.

Device revenue

Device revenue represents the delivery of physical hardware and embedded software the Company offers to facilitate recurring subscription services. This includes (i) BCDR devices, which enable business continuity and disaster recovery services to be provided to the MSP, and the proprietary software that is embedded on those devices enabling intelligent backup and (ii) networking devices, which refers to the Company's collection of integrated WiFi access points, switches, routers and managed power offerings that enable MSPs to efficiently offer highly performant and reliable cloud-managed networking to their SMB customers.

The Company recognizes device revenue upon delivery to the customer. The Company's contracts allow for customers to return devices within 60 days of purchase for a full-refund. Returns have historically been immaterial.

Professional services and other revenue

Professional services and other revenue primarily consists of implementation and consulting services, including configuration, database merging and data migration related to the Company's PSA and RMM software. The majority of the Company's professional services are billed on a time and materials basis and revenue is recognized over time as the services are performed. For contracts billed on a fixed price basis, revenue is recognized over time based on the proportion of the professional services performed in relation to the total professional services expected to be performed.

Contracts with multiple performance obligations

Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. Contracts which contain multiple performance obligations include sales of devices and subscription services and sales of business management solutions and implementation and consulting services. The Company determines standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligation.

Table of Contents

Upgrade rights

Certain device sales provide the MSP with a one-time right to upgrade the equipment within three years of the initial purchase by returning their equipment in exchange for new equipment that has a higher associated monthly service price. Upon the exercise of the right, the MSP receives a full credit of the price paid for the original device towards the purchase of the new device. At December 31, 2021, 2020 and 2019, the Company had deferred revenue of $5.1 million, $8.2 million and $11.3 million, respectively, related to these upgrade rights, which is recorded within deferred revenue, current.

Service warranty

The Company's warranty policy requires the Company to repair or replace defective devices at no cost to the customer for a typical period of three to five years after purchase, as long as the customer maintains an active subscription for the device. The Company accounts for this policy as a service-type warranty performance obligation that is fulfilled over the same period of performance as the other subscription performance obligations and therefore recognizes the associated revenue over the same period as subscription revenue.

Contract Balances

The timing of revenue recognition may differ from the timing of invoicing to customers. The Company records a receivable when revenue is recognized prior to invoicing and payment will become due solely based on the passage of time, a contract asset when revenue is recognized prior to invoicing and payment is contingent upon transfer of control of another separate performance obligation, or deferred revenue when payment is received prior to the recognition of revenue. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining balance of deferred revenue is recorded as non-current.

Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 90 days from the date of invoice. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts generally do not include a significant financing component.

Cost of Revenue

The Company includes costs directly related to revenue as a component of cost of revenue. Personnel costs associated with cost of revenue consist of salaries, benefits, bonuses, payroll taxes and stock-based compensation expense.

Subscription

Subscription cost of revenue consists of costs directly related to the Company's subscription services, including personnel costs related to operating its data centers and customer support operations, hosting and data center related costs, third-party software licenses and allocated facilities and overhead costs.

Device

Device cost of revenue consists of hardware, manufacturing, shipping and logistics and personnel costs associated with assembling the Company's devices, as well as allocated facilities and overhead costs.

Professional services and other

Professional services and other cost of revenue consists primarily of personnel costs associated with delivering these services, as well as allocated facilities and overhead costs.

Depreciation and amortization

Cost of revenue includes depreciation of its data center infrastructure and amortization of the Company's technology acquired intangible assets.

Operating expenses

The Company's operating expenses consist of sales and marketing, research and development and general and administrative expenses, as well as depreciation and amortization. Personnel costs are the most significant component of operating expenses and consist of salaries, benefits, bonuses, sales commissions, payroll taxes and stock-based compensation expense, as well as the related overhead costs to support the Company's staff.

Sales and marketing

Table of Contents

Sales and marketing expenses consist primarily of personnel costs and the related overhead costs to support the Company's staff, costs for events and travel, costs of general marketing and promotional activities, payment processing fees and allocated facilities and overhead costs. The Company expenses all advertising costs when incurred. The Company incurred advertising expense of $12.5 million, $7.3 million and $11.3 million during 2021, 2020 and 2019, respectively, as a component of sales and marketing expense.

Research and development

Research and development expenses consist primarily of personnel costs and the related overhead costs to support the Company's staff, third-party professional fees and allocated facilities and overhead costs.

General and administrative

General and administrative expenses consist primarily of personnel costs and the related overhead costs to support the Company's staff across the corporate functions of executive, finance, human resources, information technology, internal operations and legal, as well as third-party professional fees, bad debt expense, travel and facilities costs.

Depreciation and amortization

Depreciation and amortization expenses not included in cost of revenue consist of amortization of tradenames and partner relationship acquired intangible assets as well as depreciation of other property and equipment such as leasehold improvements, furniture and fixtures, and computer equipment.

Leases

The Company determines if an arrangement is or contains a lease at inception by assessing whether the arrangement contains an identified asset and whether the Company has the right to control the identified asset. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments in order to obtain the right to use the asset over the lease term. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. The Company elected to combine lease and non-lease components for its office and equipment leases, but remove the non-leases components from leases of colocated data centers, as permitted. ROU assets are based on the measurement of the lease liability and also include any lease prepayments and any initial direct costs incurred, offset by tenant incentives received by the Company. For leases with an initial term of 12 months or less, the Company does not recognize a ROU asset and corresponding lease liability. Rent expense for the Company’s operating leases is recognized on a straight-line basis over the lease term.

Generally, the Company’s leases do not provide an implicit interest rate, and therefore the Company uses its incremental borrowing rate based on the estimated rate of interest for a collateralized borrowing over a similar term of the lease payments at the commencement date. The Company includes options to extend or terminate the lease in the determination of the ROU asset and corresponding lease liability when it is reasonably certain the Company will exercise the option.

Fair Value of Financial Instruments and Fair Value Measurements

The Company determines the fair value of financial instruments based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

Level 1 Inputs: Unadjusted quoted prices for identical assets or liabilities in active markets.

Level 2 Inputs: Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar instruments in markets that are not active, and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Inputs: Significant inputs into the valuation model are unobservable.

The Company does not have any recurring assets or liabilities whose values are determined by Level 2 or Level 3 inputs. The recorded amounts of the Company's cash, accounts receivable, inventory, other assets, accounts payable, accrued expenses and other liabilities and deferred revenue approximate their fair values principally because of their short-term nature.

Income Taxes

Income tax expense includes U.S. (federal and state) and foreign income taxes. Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases, as well as net operating loss and tax credit carryforwards. Deferred tax assets represent amounts available to reduce income taxes payable in future periods. Deferred

Table of Contents

tax assets are evaluated for future realization and reduced by a valuation allowance to the extent the Company believes they will not be realized. The Company considers many factors when assessing the likelihood of future realization of deferred tax assets, including its cumulative loss experience, expectations of future earnings, the carry-forward periods available for tax reporting purposes, and other relevant factors. The effects of the COVID-19 pandemic on the business make estimates of future earnings in relevant jurisdictions more challenging. Deferred income tax assets and liabilities are adjusted for the effects of changes in tax laws and tax rates on the date of enactment.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits are recognized from such positions based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Interest and penalties related to unrecognized tax benefits are recognized within income tax expense.

Net Income (Loss) per Share

Basic net income (loss) per share attributable to common stockholders is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. The diluted net income (loss) per share attributable to common stockholders is calculated after giving effect to all potentially dilutive securities outstanding for the period.

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), (“ASC 842”). ASC 842 amends a number of aspects of lease accounting under ASC Topic 840 — Leases (“ASC 840”), including requiring lessees to recognize almost all leases with a term greater than one year as an ROU asset and corresponding lease liability, measured at the present value of the lease payments. ASC 842 provides a number of optional practical expedients in transition. On January 1, 2021, the Company adopted ASC 842 using the modified retrospective approach, and elected the practical expedients to (i) not reassess its prior conclusions about lease identification under the new standard, (ii) not reassess lease classification, and (iii) not reassess initial direct costs. The Company did not elect the practical expedient allowing the use-of-hindsight, which would require the Company to reassess the lease term of its leases based on all facts and circumstances through the effective date.

Upon adoption of ASC 842 the Company recognized operating lease assets of $35.8 million and operating lease liabilities of $46.3 million at January 1, 2021. Prior period amounts were not restated and are reported in accordance with ASC 840.

In June 2016, the FASB issued ASC 326. This standard changes the impairment model for most financial assets, including trade receivables and financial instruments and requires the Company to use a forward-looking expected loss method, which may result in earlier recognition of allowances for losses and require expected credit losses to be reflected as allowances rather than reductions in the amortized cost basis of financial assets. The Company ceased to be an EGC as of December 31, 2021, and therefore has adopted the standard, with the initial application of ASC 326 beginning on January 1, 2021. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. Refer to Accounts Receivable Net of Allowance for Expected Credit Losses for the Company's application of the standard.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASC 740”), which simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related (i) to the approach for intraperiod tax allocation, (ii) the methodology for calculating income taxes in an interim period and (iii) the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. The standard is currently effective for publicly traded companies. The Company ceased to be an EGC as of December 31, 2021, and therefore has adopted the standard, with the initial application of the standard beginning on January 1, 2021. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

In October 2021,the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer to recognize and measure contract assets and liabilities acquired in a business combination in accordance with the revenue recognition guidance of ASC 606, rather than adjust them to fair value at the acquisition date. The amendment is expected to result in the acquirer recognizing contract assets and contract liabilities at the same values recorded by the acquired company. As permitted, the Company has elected to early adopt the amendment during the fourth quarter of 2021, applying the provisions of the standard to all business combinations during the fiscal year. The adoption did not have a material impact on the Company's consolidated financial statements.

Contract Balances

Contract assets represent amounts for which the Company has recognized revenue, pursuant to its revenue recognition policy, for contracts that have not yet been invoiced to customers where there is a remaining performance obligation. Contract assets relate to contractual arrangements with both a subscription and a device or professional service performance obligation. Amounts are recorded as a current asset or a non-current asset based on the amounts anticipated to be billed within one year, net of expected credit losses, as of the balance sheet date.

8. Acquisitions

In March 2021, the Company acquired BitDam Ltd., an Israel-based cyber threat detection company (“BitDam”). The business combination was accounted for under the acquisition method of accounting. The consideration paid was allocated to the tangible and intangible assets acquired and liabilities assumed based on their fair values as of the acquisition date. As of December 31, 2021, the Company has completed the valuation of the assets acquired and liabilities assumed, including the fair value of acquired intangible assets. The allocation of the purchase consideration is as follows (in thousands):

2020 Credit Agreement

On October 23, 2020, Datto, Inc., as borrower (the “Borrower”), and certain direct and indirect wholly-owned subsidiaries of Datto, entered into a credit agreement with the lenders party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent (the "2020 Credit Agreement"). The 2020 Credit Agreement is guaranteed by certain direct and indirect subsidiaries of Datto (the “Guarantors,” and, together with the Borrower, the “Loan Parties”) and is supported by a security interest in substantially all of the Loan Parties’ personal property and assets, subject to customary exceptions, as defined in the 2020 Credit Agreement.

The 2020 Credit Agreement provides for an initial $200 million in commitments for revolving credit loans, which may be increased or decreased under specific circumstances, with a $40.0 million letter of credit sublimit and a $100.0 million alternative currency sublimit. In addition, the 2020 Credit Agreement provides for the ability of the Borrower to request term loan facilities. Borrowings pursuant to the 2020 Credit Agreement may be used for working capital and other general corporate purposes, including for acquisitions permitted under the 2020 Credit Agreement, and are scheduled to mature on October 23, 2025. The 2020 Credit Agreement contains certain customary representations and warranties and affirmative and negative covenants.

The interest rates applicable to the revolving borrowings under the 2020 Credit Agreement, are, at the Borrower’s option, either (i) a base rate, equal to the greater of (a) the Prime Rate, (b) the Federal Funds Effective Rate plus 0.5% or (c) the Adjusted LIBO Rate for a one month Interest Period (each term as defined in the 2020 Credit Agreement) plus 1%, or (ii) the Adjusted LIBO Rate equal to the LIBO Rate for the applicable Interest Period, plus in the case of each of clauses (i) and (ii), the Applicable Rate (as defined in the 2020 Credit Agreement). The Applicable Rate (i) for base rate loans ranges from 0.25% to 1.0% per annum and (ii) for LIBO Rate loans ranges from 1.25% to 2.0% per annum, in each case, based on the Senior Secured Net Leverage Ratio (as defined in the 2020 Credit Agreement). The 2020 Credit Agreement provides for a commitment fee ranging from 0.20% to 0.35% per annum of the average daily undrawn portion of the revolving commitments based on the Senior Secured Net Leverage Ratio (as defined in the 2020 Credit Agreement).

As of December 31, 2021, the 2020 Credit Agreement is undrawn, with the exception of $1.9 million of outstanding letters of credit. The Company incurred debt issuance costs for the 2020 Credit Agreement of $1.2 million, which are being amortized over the term of the 2020 Credit Agreement as a component of interest expense. The Company recorded amortization of the debt issuance costs of $0.3 million as interest expense during 2021.

2017 Credit Agreement

Prior to April 2019, the Company had outstanding balances under a credit agreement entered in 2017, which was comprised of a $520 million term loan facility and a $35 million revolving credit facility (the "2017 Credit Agreement").

13. Stockholders' Equity

Authorized capital stock consists of 500,000,000 shares of common stock, par value $0.001 per share, and 50,000,000 shares of undesignated preferred stock, par value $0.001 per share. As of December 31, 2021 and 2020 there were 163,991,681 and 161,420,016 shares, respectively, of common stock issued and outstanding.

Common Stock

Dividend Rights—The holders of common stock are entitled to receive dividends out of funds legally available if the Board, in its discretion, determines to issue dividends and then only at the times and in the amounts the Board may determine. Any future determination to pay dividends is subject to compliance with covenants in current and future agreements governing the Company's and its subsidiaries’ indebtedness, and will depend on the Company's results of operations, financial condition, capital requirements and other factors the Board may deem relevant.

Voting Rights—Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders.

Preemptive or Similar Rights—The common stock is not entitled to preemptive rights, and is not subject to conversion, redemption or sinking fund provisions.

Preferred Stock

The Board may, without stockholder approval but subject to any limitations prescribed by law, direct the issuance of shares of preferred stock (in one or more series or classes), create additional series or classes of preferred stock and establish the number of shares to be included in such series or classes. The Board is also authorized, at the time of issuance, to determine the designations, powers, preferences, privileges and relative participating, optional or special rights as well as the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences of such preferred stock, any or all of which may be greater than the rights of the common stock. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of the Company's common stock. As of December 31, 2021 and 2020, the Company did not have any shares of preferred stock outstanding and currently has no plans to issue shares of preferred stock.

Treasury Stock

During 2018, the Company purchased 362,126 shares of common stock from stockholders at fair value, which shares are held as treasury stock and carried at their cost basis of $3.6 million on the Company's consolidated balance sheets. There have been no treasury stock transactions in subsequent periods.

14. Stock-Based Compensation

The Company has equity awards outstanding under various plans, as described further below.

Datto 2020 Omnibus Incentive Plan

In conjunction with the IPO, in October 2020, the Board adopted the Datto Holding Corp. Omnibus Incentive Plan (the “2020 Plan”) in order to align the interests of the participants with the interests of the Company's stockholders. The 2020 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), bonus stock, dividend equivalents, other stock-based awards, substitute awards, annual incentive awards and performance awards to employees, consultants, and members of the Board. Authorized shares under the 2020 Plan automatically increase each January 1st that occurs after the effective date for 10 years, by 5% of the outstanding number of shares of the Company's common stock on the immediately preceding December 31st, or such lesser number of shares as determined by the Board. See below for a reconciliation of shares of the Company’s common stock reserved for issuance under the 2020 Plan. Under the 2020 Plan, 4,185,843 restricted stock units and 80,000 options were outstanding as of December 31, 2021.

2017 Stock Option Plan

In December 2017, the Company adopted the 2017 Stock Option Plan (the “2017 Datto Plan”), as amended, which provides for grants of stock options to attract and retain talented employees, directors, officers, and consultants. As of December 31, 2021, 6,715,132 stock options were outstanding under the 2017 Datto Plan. No additional awards are allowed to be issued under the 2017 Datto Plan as a result of the adoption of the 2020 Plan.

Other Equity Plans

The Company also has outstanding options which were issued under the Autotask Superior Holdings 2013 Stock Option Plan (the “Autotask Plan”), which was frozen at the time of the Autotask Transaction. All outstanding awards were fully vested as of the date of the Autotask Transaction, and the options settle in the Company's common stock. As of December 31, 2021, 259,874 of stock options were outstanding under the Autotask Plan. No additional awards are allowed to be issued under the Autotask Plan.

IPO Contingent Options issued under the 2017 Datto Plan ("IPO Contingent Options")

Under the 2017 Datto Plan, the Company had issued certain awards which contained both a time-based and a performance-based vesting condition, which was the closing of an IPO. Since the closing of an IPO is not deemed probable until consummated, stock-based compensation expense for the IPO Contingent Options commenced during the fourth quarter of 2020 as a result of the Company's IPO.

During 2020 the Board approved a modification of the vesting terms of the IPO Contingent Options. The original terms provided for 25% to vest upon an IPO and 6.25% to vest quarterly thereafter. The modified vesting terms provided for 25% to vest upon an IPO, but to the extent the IPO occurred after the second anniversary of the grant date, in addition to the 25%, an additional 6.25% would vest for each quarter of service provided, commencing on the second anniversary of the grant date.

The modification of the vesting terms of these awards resulted in accounting for the awards as a new grant, and as such the Company updated the fair value of each stock option award using the Black-Scholes option pricing model on the modification date. The resulting compensation is recorded under the accelerated attribution method, resulting in a total of $23.1 million of expense for the IPO Contingent Options recorded during the fourth quarter of 2020, including a significant amount of expense recorded upon completion of the IPO.

The total fair value of stock options that vested during 2021, 2020 and 2019 was $25.9 million, $23.8 million and $6.9 million, respectively. The years ended December 31, 2021 and 2020 include the value of IPO Contingent Options which commenced vesting upon completion of the IPO.

The aggregate intrinsic value of stock options exercised during 2021, 2020 and 2019 was $35.5 million, $6.6 million and $0.8 million, respectively.

The weighted average grant-date fair value of stock options granted during 2021, 2020 and 2019, was $11.60, $15.42 and $5.62, respectively.

The estimated grant-date fair value of stock options was calculated using the Black-Scholes option-pricing model, based on the following range of assumptions:


	Year Ended December 31,
	2021		2020		2019
Expected dividend yield	—	%	—	%	—	%
Expected volatility	44.7% - 47.2%		65.0	%	45.0% - 50.0%
Expected term (years)	6.1		6.1 - 6.25		6.25
Risk-free interest rate	0.7% - 1.0%		0.4	%	1.8% - 2.5%
Fair value of underlying common stock	$25.23 - $25.54		$22.17 - 22.64		$10.47 - 12.78

The valuation of stock options granted during 2020, including the final valuation of the IPO Contingent Options which were modified during 2020, was based upon an interpolation of the Company’s stock price from the beginning of the year of $14.50 to the IPO price of $27.00.

As of December 31, 2021, unrecognized compensation expense related to outstanding stock options was $21.2 million, which is expected to be recognized over the remaining weighted average term of 1.8 years.

Datto 2021 Employee Stock Purchase Plan

In May 2021, shareholders approved the Datto Holding Corp. 2021 Employee Stock Purchase Plan (“ESPP”). The ESPP contains a component intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code (the “423 Component”) and a component primarily related to purchases by international employees. The ESPP provides all eligible Datto employees the opportunity to contribute up to 15% of their base earnings and other eligible compensation to purchase shares of Datto common stock. A participant can purchase a maximum of 1,000 shares of Datto common stock per biannual offering period, although participants in the 423 Component cannot purchase shares that would accrue at a rate which exceeds $25,000 of fair market value of Datto common stock (determined based on the fair market value on the first day of each offering period) for each calendar year. The purchase price is equal to 85% of the fair market value of Datto common stock on the first or last day of the offering period, whichever is lower. There are 3,221,541 shares available for issuance under the ESPP, although none were outstanding at December 31, 2021. The pool of shares available for issuance under the ESPP is subject to an annual increase on the first day of each year beginning on January 1, 2022 and annually thereafter ending in 2031 equal to the lesser of (i) 1% of all classes of the Company’s shares outstanding on the last day of the immediately preceding calendar year and (ii) such smaller number of shares as may be determined by the Board; provided, however, no more than 16,000,000 shares may be issued in total under the 423 Component.

Approximately 0.2 million shares were purchased at the end of the offering period in January 2022, based on the enrollment and stock price as of December 31, 2021. The Company withheld $3.2 million on behalf of employees for these purchases under the ESPP, which was included in accrued expenses and other current liabilities within the condensed consolidated balance sheets as of December 31, 2021.

The fair value of shares issued under the ESPP is estimated on the grant date using the Black-Scholes option pricing model. As of December 31, 2021, unrecognized compensation expense related to the ESPP was $0.1 million, which is expected to be recognized over the remaining weighted average term of 0.1 years.

The reconciliation of the U.S. federal statutory income tax rate to the Company's effective tax rate for the periods indicated is as follows:


	For the Year Ended December 31,
	2021		2020		2019
U.S. federal statutory income tax rate	21.0	%	21.0	%	21.0	%

Other	(0.2)		1.9		(0.6)
Effective tax rate	16.2	%	26.4	%	7.5	%

The primary differences between the U.S. federal statutory income tax rate and the Company’s effective tax rate for 2021 are the favorable impact of an amendment to our 2018 and 2019 federal tax returns as a result of clarification of certain tax guidance, a change in tax law in the state of Connecticut resulting in the ability to utilize additional research and development credits generated in prior years which impacted the valuation allowance, and research and development credits generated in the current year, partially offset by the impact of state income taxes and permanent differences for non-deductible expenses. The primary differences between the U.S. federal statutory income tax rate and the Company’s effective tax rate for 2020 are the unfavorable impact of permanent differences related to stock-based compensation for certain employees and the impact of state income taxes, partially offset by the favorable impact of research and development credits and foreign operations.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was signed into law. The CARES Act did not have a material impact on the Company's provision for income taxes for 2021 or 2020.

The realizability of the deferred tax assets is primarily dependent on our ability to generate sufficient taxable income in future periods. The need for a valuation allowance requires an assessment of both positive and negative evidence when determining whether it is more-likely-than-not that deferred tax assets are recoverable. Such assessment is required on a jurisdiction-by-jurisdiction basis. In making such assessment, significant weight is given to evidence that can be objectively verified. Based on cumulative taxable income, projections for future taxable income, and the timing of reversal of deferred tax liabilities, the Company has recorded a valuation allowance against certain deferred tax assets.

Undistributed earnings of certain foreign subsidiaries were $26.6 million as of December 31, 2021. The Company considers the current earnings and any future earnings of the foreign subsidiaries to be indefinitely reinvested, and therefore does not record deferred taxes related to these earnings. Upon repatriation of earnings, in the form of dividends or otherwise, the Company may be subject to both U.S. income taxes (subject to a dividends received deduction) and withholding taxes payable to certain foreign jurisdictions. The amount of deferred tax liability that would result from the repatriation of earnings is immaterial at December 31, 2021.

Tax positions for the Company and its subsidiaries are subject to income tax audits in multiple tax jurisdictions throughout the world. The Company has evaluated its tax positions and has determined it has unrecognized tax benefits as a result of certain uncertain tax positions. The following table summarizes the balance of unrecognized tax benefits, which is recorded as a component of deferred income taxes on the consolidated balance sheets as of December 31, 2021 and 2020 (in thousands):


	Amount
Balance at December 31, 2019	$	3,842
Additions (reductions) related to current year	931
Additions (reductions) related to prior years positions	(12)


Balance at December 31, 2020	$	4,761
Additions (reductions) related to current year	1,179
Additions (reductions) related to prior years positions	(822)


Balance at December 31, 2021	$	5,118

The unrecognized tax benefits for the tax years ended December 31, 2021, 2020 and 2019 include $5.1 million, $4.8 million and $3.8 million, respectively, that would impact the effective tax rate if recognized. The Company does not currently anticipate significant changes in its unrecognized tax benefits over the next 12 months. The Company has accrued immaterial interest and penalties related to uncertain tax positions as of December 31, 2021.

The Company's tax returns remain open to examination as follows: U.S. federal, 2013 through 2020; U.S. states, generally 2014 through 2020; and significant foreign jurisdictions, generally 2017 through 2020.

16. Employee Benefit Plans

The Company has a defined contribution 401(k) retirement plan covering U.S. employees who have completed ninety days of service and who are at least 21 years of age. The Company makes safe harbor matching contributions equal to 100% of employee contributions up to 3% of compensation plus 50% of employee contributions between 3% and 6% of compensation. The Company made matching contributions of $7.5 million, $6.1 million and $4.8 million during 2021, 2020 and 2019, respectively.

17. Net Income (Loss) per Share

Basic net income per share attributable to common stockholders is calculated by dividing the net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders is calculated by giving effect to all potential shares of common stock, including the Company's outstanding stock options, common stock related to unvested RSUs, and the estimated number of shares to be issued under the ESPP based upon the enrollment and stock price as of December 31, 2021, to the extent such potential shares are dilutive. For the purpose of computing diluted earnings per share, options with a performance-based vesting condition are considered contingently issuable, and such contingent shares are included in the denominator for computing diluted net income per share only once the performance condition is met, and only to the extent such options are dilutive. As described in Note 14. Stock-Based Compensation, the IPO Contingent Options contained a performance-vesting condition, and were only considered in computing diluted net income per share after the IPO in October of 2020. The calculation of basic and diluted income (loss) per share is as follows (in thousands, except share and per share amounts):

18. Related Party Transactions

Vista, the Company's majority shareholder, is a U.S.-based investment firm. During 2021, 2020 and 2019, the Company paid a total of $0.1 million, $0.7 million, and $1.1 million, respectively, for consulting services, executive recruitment, and other services provided by Vista and Vista affiliates.

Sales to Vista portfolio companies amounted to $0.3 million, $0.2 million, and $0.1 million for 2021, 2020 and 2019, respectively, with such amounts included in subscription revenue in the Company's consolidated statements of operations. At December 31, 2021 and 2020, the Company had immaterial accounts receivable from Vista portfolio companies on the consolidated balance sheets.

Business and Basis of Presentation

Description of Business

Datto Holding owns 100% of Merritt Holdco, Inc. (“Merritt Holdco”), which owns 100% of Datto, Inc., the primary operating company.

Datto Holding is a holding company with no material operations of its own, conducting substantially all of its activities through its subsidiaries. Datto Holding has no direct outstanding debt obligations. Datto, Inc. is the borrower and Merritt Holdco is a guarantor under the 2020 Credit Agreement. Merritt Holdco and Datto, Inc. are limited in their ability to declare dividends or make any payment on account of their capital stock to, directly or indirectly, fund a dividend or other distribution to Datto Holding under the 2020 Credit Agreement.

Basis of Presentation

These condensed financial statements have been presented on a “parent-only” basis. Under a parent-only presentation, Datto Holding’s investments in subsidiaries are presented under the equity method of accounting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. As such, these parent-only statements should be read in conjunction with the accompanying notes to consolidated financial statements.

20. Restructuring

In response to the COVID-19 pandemic, the Company undertook various measures during the second quarter of 2020 to mitigate the risk of potential reductions in revenue and delays or reductions in payments from the Company's customers. The measures included a focus on the Company's cost structure to better match expenditures to its revised forecasts of revenue and cash generation activities at that time. As a result of this review, the Company incurred approximately $3.8 million for restructuring activities in the second quarter of 2020, primarily related to severance for a reduction in workforce, including $0.6 million in cost of revenue and $3.2 million in operating expenses. All associated benefits were paid as of December 31, 2020.

21. Subsequent Events

On January 20, 2022, the Company announced that it had acquired threat detection and response company Infocyte for approximately $44 million, extending Datto’s security capabilities that protect, detect, and respond to cyber-threats found within endpoints and cloud environments.

Management's Statement Of Responsibility For Financial Statements

Datto's management has prepared and is responsible for the consolidated financial statements and the related financial data contained in this report. These financial statements, which include estimates, were prepared in accordance with accounting principles generally accepted in the United States of America applied on a consistent basis and include amounts that are estimates and that are based on judgment. Management uses its best judgment to ensure that such statements reflect fairly the consolidated financial position, results of operations and cash flows of the Company.

The Audit Committee of the Board of Directors reviews and monitors the consolidated financial statements and accounting policies of the Company. These financial statements and policies are reviewed regularly by management and such financial statements are audited by our independent registered public accounting firm, Ernst & Young LLP. The independent registered public accounting firm has full and free access to the Audit Committee and meet with the committee, with and without management present.

Management’s Annual Report on Internal Control Over Financial Reporting

Datto's management is responsible for establishing and maintaining adequate “internal control over financial reporting,” as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Securities Exchange Act of 1934 (the "Exchange Act"). Management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2021 based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2021. Our independent registered public accounting firm has issued an auditors’ report on the effectiveness of our internal control over financial reporting, provided below.

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that it is also accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2021, the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2021.

Changes in Internal Control Over Financial Reporting

As previously disclosed under the section titled “Controls and Procedures” included under Part II, Item 9A of our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 11, 2021, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of December 31, 2020, because of a material weakness in internal control over financial reporting. Specifically, we identified deficiencies in information technology ("IT") general controls and process level controls.

During the fiscal year ended December 31, 2021, management implemented our previously disclosed remediation plan that included:

•Replacing certain legacy IT systems that have inherent control limitations with SaaS tools that support enhanced access and application controls;

•Engaging external resources to assist with remediation efforts and internal control execution, as well as providing additional training to our personnel;

•Hiring additional internal resources with appropriate knowledge and expertise to effectively operate financial reporting processes and internal controls; and

112

Table of Contents

•Implementing enhanced review procedures and analysis over the segregation of duties in IT systems.

Based upon the actions taken and our testing and evaluation of the effectiveness of our internal controls, we have concluded the material weakness no longer existed as of December 31, 2021.

Inherent Limitation on the Effectiveness of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, and not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Datto Holding Corp.

Opinion on Internal Control Over Financial Reporting

We have audited Datto Holding Corp.’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Datto Holding Corp. (the “Company”) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, and the related consolidated statements of operations, comprehensive income (loss), changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes of the Company and our report dated February 23, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Controls over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
