Cambium Networks Reports Second Quarter 2020 Financial Results

ROLLING MEADOWS, IL., Aug. 11, 2020 — Cambium Networks Corporation (“Cambium Networks”) (NASDAQ: CMBM), a leading provider of wireless networking infrastructure solutions, today announced financial results for the second quarter 2020 ended June 30, 2020.

Refer to Supplemental Financial Information accompanying this press release for a reconciliation of GAAP to non-GAAP numbers and for reconciliation of adjusted EBITDA for the second quarter ended June 30, 2020.

“Wireless broadband connectivity is vital and essential infrastructure for people around the world and is a lifeline for most communities,” said Atul Bhatnagar, president and CEO. “There is an increased secular need for fixed wireless broadband infrastructure. We are at the start of a new upgrade cycle to gigabit wireless solutions including our 60 GHz millimeter wave, CBRS solutions and emerging 5G products, and cloud powered enterprise Wi-Fi 6.”

Bhatnagar continued, “Fixed wireless broadband is a critically important networking fabric being accelerated by 5G standards to connect our local communities and its importance proved especially true during the COVID pandemic. Our business strengthened during the second quarter 2020, and during a period of unprecedented uncertainty, our employees and global channel rose to the occasion. Cambium Networks is now leaner, delivering improved financial performance, and better positioned for our next stage of growth.”

Revenues of $62.3 million for the second quarter 2020 decreased $6.9 million year-over-year, as a result of softer demand for defense related products which impacted Point-to-Point revenues, lower demand for Point-

to-Multi-Point products due to a technology transition, and the impact of global shutdowns and other restrictions imposed to combat the COVID pandemic to enterprise Wi-Fi solutions. Revenues for the second quarter 2020 increased by $1.9 million compared to $60.4 million for the first quarter 2020, driven by higher Point-to-Multi-Point revenues due to service providers scaling networks due to requests for increased capacity and better than anticipated field deployments, offset by lower demand for enterprise Wi-Fi solutions due to the impact of the COVID pandemic, and lower Point-to-Point revenues.

GAAP gross margin for the second quarter 2020 was 48.9%, compared to 49.6% for the second quarter 2019, and 50.7% for the first quarter 2020. GAAP operating income for the second quarter 2020 was $4.8 million, compared to an operating loss of $9.4 million during the second quarter 2019, and operating income of $0.4 million for the first quarter 2020. GAAP net income for the second quarter 2020 was $3.3 million, or net earnings of $0.13 per diluted share, compared to net loss of $20.4 million, or $1.47 per diluted share for the second quarter 2019, and net loss for the first quarter 2020 of $0.8 million, or a net loss of $0.03 per diluted share.

Non-GAAP gross margin for the second quarter 2020 was 49.2%, compared to 50.1% for the second quarter 2019, and 51.0% for the first quarter 2020. Non-GAAP operating income for the second quarter 2020 was $6.5 million, compared to $7.1 million for the second quarter 2019, and $3.0 million for the first quarter 2020. Non-GAAP net income for the second quarter 2020 was $4.3 million, or $0.16 per diluted share, compared to $3.9 million, or $0.15 per diluted share for the second quarter 2019, and $1.4 million, or $0.05 per diluted share for the first quarter 2020. For the second quarter 2020, adjusted EBITDA was $7.7 million or 12.3% of revenues, compared to adjusted EBITDA of $8.1 million or 11.8% of revenues for the second quarter 2019, and $4.4 million or 7.3% of revenues for the first quarter 2020.

Cash provided by operating activities was $26.2 million for the second quarter 2020, compared to cash provided by operating activities of $6.0 million for the second quarter 2019, and $0.8 million cash used in operating activities for the first quarter 2020. Cash totaled $37.4 million as of June 30, 2020, $33.8 million lower than June 30, 2019, due primarily to the paydown of $40.5 million of long-term debt and increased by $13.0 million from March 31, 2020. The increase in cash balance for the second quarter 2020 from the first quarter 2020 was primarily the result of an increase in net income, strong cash collections resulting in a decrease in accounts receivable, an increase in accounts payable, a reduction in inventories, offset by a paydown of $10.0 million on the revolving credit facility.

All statements other than statements of historical fact contained in this document, including statements regarding our future results of operations and financial position, business strategy and plans and objectives of management for future operations, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions. The forward-looking statements in this document are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this document and are subject to a number of risks, uncertainties and assumptions including those described in the “Risk factors” section of our 2019 Form 10-K filed with the Securities and Exchange Commission on March 23, 2020, and most recent Form 10-Q filed on May 13, 2020. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Some of the key factors that could cause actual results to differ from our expectations include: the

unpredictability of our operating results; our inability to predict and respond to emerging technological trends and network operators’ changing needs; risks presented by the global COVID-19 pandemic, which could significantly disrupt our manufacturing, sales and other operations and negatively impact our financial results; our reliance on third-party manufacturers, which subjects us to risks of product delivery delays and reduced control over product costs and quality; our reliance on distributors and value-added resellers for the substantial majority of our sales; the inability of our third-party logistics and warehousing providers to deliver products to our channel partners and network operators in a timely manner; the quality of our support and services offerings; our expectations regarding outstanding litigation; our or our distributors’ and channel partners’ inability to attract new network operators or sell additional products to network operators that currently use our products; and negatively impact our financial results; the difficulty of comparing or forecasting our financial results on a quarter-by-quarter basis due to the seasonality of our business; our limited or sole source suppliers’ inability to produce third-party components to build our products; the technological complexity of our products, which may contain undetected hardware defects or software bugs; our channel partners’ inability to effectively manage inventory of our products, timely resell our products or estimate expected future demand; credit risk of our channel partners, which could adversely affect their ability to purchase or pay for our products; our inability to manage our growth and expand our operations; unpredictability of sales and revenues due to lengthy sales cycles; our inability to maintain an effective system of internal controls, produce timely and accurate financial statements or comply with applicable regulations; our reliance on the availability of third-party licenses; risks associated with international sales and operations; current or future unfavorable economic conditions, both domestically and in foreign markets; and our inability to obtain intellectual property protections for our products.

Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events or otherwise.

Use of non-GAAP (Adjusted) Financial Measures

In addition to providing financial measurements based on generally accepted accounting principles in the United States (GAAP), we provide additional financial metrics that are not prepared in accordance with GAAP (non-GAAP), including Adjusted EBITDA, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income and non-GAAP operating margin, non-GAAP pre-tax income, non-GAAP provision for income taxes, non-GAAP net income, and non-GAAP fully weighted basic and diluted shares. Management uses these non-GAAP financial measures, in addition to GAAP financial measures, to understand and compare operating results across accounting periods, for financial and operational decision making, for planning and forecasting purposes, to measure executive compensation and to evaluate our financial performance. We believe that these non-GAAP financial measures help us to identify underlying trends in our business that could otherwise be masked by the effect of the expenses that we exclude in the calculations of the non-GAAP financial measures.

Accordingly, we believe that these financial measures reflect our ongoing business in a manner that allows for meaningful comparisons and analysis of trends in the business and provides useful information to investors and others in understanding and evaluating our operating results, enhancing the overall understanding of our past performance and future prospects.  Excluding these non-GAAP measures eliminate the variability caused by share-based compensation as a result of the variety of equity awards used by other companies and the varying methodologies and assumptions used, the variability caused by purchase accounting and provide a more relevant measure of operating performance. Although the calculation of non-GAAP financial measures may vary from company to company, our detailed presentation may facilitate

analysis and comparison of our operating results by management and investors with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results in their public disclosures. These non-GAAP financial measures are discussed below.

Adjusted EBITDA is defined as net income as reported in our consolidated statements of income excluding the impact of (i) interest expense (income), net; (ii) income tax provision (benefit); (iii) depreciation and amortization expense; (iv) Sponsor management fees associated with advisory services, (v) share-based compensation expense, (vi) one-time acquisition costs, and (vii) restructuring expenses. EBITDA is widely used by securities analysts, investors and other interested parties to evaluate the profitability of companies. EBITDA eliminates potential differences in performance caused by variations in capital structures (affecting net finance costs), tax positions (such as the availability of net operating losses against which to relieve taxable profits), the cost and age of tangible assets (affecting relative depreciation expense) and the extent to which intangible assets are identifiable (affecting relative amortization expense). We adjust EBITDA to also exclude Sponsor management fees, in order to eliminate the impact on reported performance caused by these fees, which are related to our past ownership structure. We adjust EBITDA for share-based compensation expense which is a non-cash expense that varies in amount from period to period and is dependent on market forces that are often beyond Cambium Networks control. As a result, management excludes this item from Cambium Networks internal operating forecasts and models. We also adjust EBITDA to exclude one-time acquisition costs and restructuring expenses as these relate to events outside of the ordinary course of continuing operations and to provide a more accurate comparison of our ongoing business results.

Non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income and non-GAAP operating margin, non-GAAP effective tax rate and non-GAAP net income are used as a supplement to our unaudited condensed consolidated financial statements presented in accordance with GAAP.  We believe these non-GAAP measures are the most meaningful for period to period comparisons because they exclude the impact of share-based compensation expense, amortization of acquired intangibles, and amortization of capitalized software costs as we do not consider these costs and expenses to be indicative of our ongoing operations.

Share-based compensation expense and associated employment taxes paid are excluded. Management may issue different types of awards, including share options, restricted share awards and restricted share units, as well as awards with performance or other market characteristics, and excludes the associated expense in this non-GAAP measure. Share-based compensation expense is a non-cash expense that varies in amount from period to period and is dependent on market forces that are often beyond Cambium Networks control while the associated employment taxes are cash-based expenses that vary in amount from period-to-period and are dependent on market forces as well as jurisdictional tax regulations that are often beyond Cambium Networks control.  In addition, in the three-month period ended June 30, 2019, Cambium Networks incurred a one-time share-based compensation expense of $16.1 million in connection with (i) the recognition of

deferred share-based compensation expense and (ii) the issuance of 2,172,000 share options, each upon the completion of our initial public offering.    

Amortization of acquired intangibles includes customer relationships, unpatented technology, patents, software, and trademarks, and are excluded since these are not indicative of continuing operations.

Amortization of capitalized software costs include capitalized research and development activities amortized over their useful life and included in cost of revenues and are excluded since these are not indicative of continuing operations.

Acquisition and integration costs consist of legal and professional fees relating to the acquisition of Xirrus. Cambium Networks excludes these expenses since they result from an event that is outside the ordinary course of continuing operations.

One-time charges associated with the completion of an acquisition including items such as contract termination costs, severance and other acquisition-related restructuring costs; costs incurred in connection with integration activities; and legal and accounting costs. Cambium Networks excludes these expenses since they result from an event that is outside the ordinary course of continuing operations.

Restructuring expenses primarily consist of severance costs for employees which are not related to future operating expenses. Cambium Networks excludes these expenses since they result from an event that is outside the ordinary course of continuing operations. Excluding these charges permits more accurate comparisons of Cambium Networks ongoing business results.

Our non-GAAP tax adjustments include the tax impacts from share-based compensation expense including excess or decremental tax benefits available to the company that are recorded when incurred, one-time and ongoing impacts from the company's valuation allowance recognized in the quarter ended June 30, 2019, and one-time tax impacts from share-based compensation expense incurred upon the completion of our initial public offering. Cambium Networks excludes these amounts to more closely approximate the company’s ongoing effective tax rate after adjusting for one-time or unique reoccurring items. The associated non-GAAP effective tax rate is also applied to the gross amount of non-GAAP adjustments for purposes of calculating non-GAAP net income in total and on a per-share basis. This approach is designed to enhance the ability of investors to understand the company's tax expense on its current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP adjustments which may not reflect actual cash tax expense.  

Non-GAAP fully weighted basic and diluted shares are shown as outstanding during the entire period presented and include dilutive shares, if their effect to earnings per share is dilutive.  We also use non-GAAP fully weighted basic and diluted shares to provide more comparable per-share results across periods.

These non-GAAP financial measures do not replace the presentation of our GAAP financial results and should only be used as a supplement to, not as a substitute for, our financial results presented in accordance with GAAP. There are limitations in the use of non-GAAP measures, because they do not include all the expenses that must be included under GAAP and because they involve the exercise of judgment concerning exclusions of items from the comparable non-GAAP financial measure. In addition, other companies may use other measures to evaluate their performance, or may calculate non-GAAP measures differently, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. We present a “Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures” in the tables below.  

The following table reconciles net income (loss) to Adjusted EBITDA, the most directly comparable financial measure, calculated and presented in accordance with GAAP (in thousands):
