Transformation Office

Market Overview • The US home security market is worth $17B and growing at 3% per annum but has become more complex with consumer demand for smart home integration • Numerous smart security options at lower price points • Successful players have checked multiple key boxes including • i) innovation ii) sales effectiveness and iii) price • DIY is expanding the overall security market with volume growth for pro install relatively flat • SMART home automation is increasingly being considered table stakes • 24x7 professional monitoring is a constant in the market Rapidly evolving Home Security marketplace… strong demand remains for professional monitoring Market Continues to Transition • Customer experience and more services will be an ever-increasing theme as more devices integrate in the smart home • Successful players need to be innovative in bringing an integrated product/service offering into a full-service experience that commands a premium price point • Price competition is expected to intensify in basic security, but consumers are still willing to pay for premium services or value proposition • Success in the basic value segment will be led by players such as SimpliSafe who have a minimal cost-to-serve (own hardware and software) and a robust Ecomm GTM model Competitive Overview Vivint - Highly effective integrated phone and field sales team with bespoke sales tools, focus on the SMART home, target market an affluent customer and charge highest RMR, lower margins, strong sales culture – focused on growth ADT - Integrated phone and field sales force, coupled with a dealer channel, exploring Ecomm. Leverages brand proposition of “stability,” interactive SMART home product set, comparable to Vivint, heavy reliance on brand and size for scale and operability – recently announced Google Partnership shows potential shift towards technology leadership and growth Low Cost DIY (e.g. SimpliSafe / Ring) – lower RMR, simple Ecomm DIY SMART home solution, a substantially better cost to serve (hardware and software), and effective digital offering/service – focused on growth Market Overview

BHS will move up market, differentiated by our premier customer experience, enabled by a strong backbone in data analytics, integrated go-to-market and best in class Brand proposition Leveraging Data • Digitize, integrate and use data analytics to track the entire customer journey from first point of contact (landing page) through sales (phone / field or Ecomm) installation, customer service and retention • Create an enterprise wide data platform to capture customer information in “one language” and redistribute throughout the organization through Business Intelligence systems that are seamlessly integrated to drive real-time business decisions and create opportunities to test new business models • Data systems will allow for a premium customer service that helps reduce the overall cost-to-serve Customer Lifetime Experience • A customer experience that is differentiated and superior to competition, predicated on delivering professional monitoring with SMART home products and services in one easy to use platform – Helping to make the complex simple • Best in class integrators and service providers throughout the customer lifecycle as represented by a “Premium” up market brand proposition • A primary and essential driver behind the transformation will be the adoption of a transformative digital strategy Integrated Sales & Product Mix • Selling to the customer the way they want to interact: Direct Channel comprised of integrated phone sales, field sales, and Ecommerce – eventually displacing the dealer model as primary unit volume • Integrate BHS brand proposition into Dealer model to provide seamless Brinks experience starting at the point of sale • Re-invent dealer program to align financial interests through shared risk of attrition and shared revenue. Lower upfront multiple and reduced guarantee period • Develop product roadmap centered on premium products and services to address the DIY / DIFM market *Dealer & Indirect term includes all channels outside of DTC BHS Opportunities and Strengths • Opportunities: Sales engine not at scale, cost to serve elevated by software, lack of control over software stack slows innovation, systems remain largely designed to support dealer network, limited BI platform (other than for “at risk” analytics), inconsistent customer engagement, improving but still higher than industry customer attrition, clarity needed in value prop and product roadmap • Strength Assessment: Low cost and long-term license agreement for world class brand in home security and IOT, establishment of discipline through Transformation Office, strong balance sheet, addition of talented management in key positions, established recurring revenue, dealer network and operational scale (competitive advantage in bulk strategy) Go-To-Market Strategy

BHS strategy – Profitable Mix of Differentiated Service and Holistic Smart Home Solutions *Dealer & Indirect term includes all channels outside of DTC Strategy Alignment Thesis • Consumers value home security. Professional 24 x 7 home security monitoring (e.g. video verification / analytics) will continue to serve as an entry point into the home to engage the customer and create opportunities for the broader ecosystem of SMART home enabled products and services anchored by home security • Low customer satisfaction with Competitors has created a “White Space” where a competitive advantage may be created through delivering an innovative and premium customer centric experience across the entire enterprise and throughout the customer journey • Customer interest in technology advancements will support the increasing penetration of interactive, home automation, and SMART security solutions and create opportunities for Brinks to create long-term and evolving engagement with its customers • Confusing and rapid changes in technology will also produce opportunities for Brinks to deliver new and integrated products and services to new and existing customers – making the complex simple • GTM strategy will be grounded on attracting a loyal persona that has high ability and willingness to pay, demands expert support, and ideally prefers professional installation, and demands lifetime excellence in support and timely service Delivering profitable accounts at scale for life Future State Current State Strategy Alignment

F. Appendix

Measures and Reconciliations We evaluate the performance of our operations based on financial measures such as revenue and "Adjusted EBITDA." Adjusted EBITDA is a non-GAAP financial measure and is defined as net income (loss) before interest expense, interest income, income taxes, depreciation, amortization (including the amortization of subscriber accounts, dealer network and other intangible assets), restructuring charges, stock-based compensation, and other non-cash or non-recurring charges. We believe that Adjusted EBITDA is an important indicator of the operational strength and performance of our business. In addition, this measure is used by management to evaluate operating results and perform analytical comparisons and identify strategies to improve performance. Adjusted EBITDA is also a measure that is customarily used by financial analysts to evaluate the financial performance of companies in the security alarm monitoring industry and is one of the financial measures, subject to certain adjustments, by which our covenants are calculated under the agreements governing our debt obligations. Adjusted EBITDA does not represent cash flow from operations as defined by generally accepted accounting principles in the United States ("GAAP"), should not be construed as an alternative to net income or loss and is indicative neither of our results of operations nor of cash flows available to fund all of our cash needs. It is, however, a measurement that we believe is useful to investors in analyzing our operating performance. Accordingly, Adjusted EBITDA should be considered in addition to, but not as a substitute for, net income, cash flow provided by operating activities and other measures of financial performance prepared in accordance with GAAP. As companies often define non-GAAP financial measures differently, Adjusted EBITDA as calculated by Monitronics should not be compared to any similarly titled measures reported by other companies.
