Cambium Networks Reports First Quarter 2022 Financial Results

ROLLING MEADOWS, Ill., May 5, 2022 — Cambium Networks Corporation (“Cambium Networks”) (NASDAQ: CMBM), a leading provider of wireless networking infrastructure solutions, today announced financial results for the first quarter 2022 ended March 31, 2022.

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 first quarter ended March 31, 2022.

“We faced supply chain challenges within our industry which impacted our first quarter results as a consequence of two unexpected events,” said Atul Bhatnagar, president and CEO. “A Chinese government COVID lockdown in Shenzhen impacted manufacturing during the middle of March, and during the last two weeks of the quarter, a lockdown in Shanghai shuttered our distribution and warehousing facility. We remain confident that once the supply chain recovers, Cambium expects improved financial performance.”

Bhatnagar continued, “Cambium’s gigabit wireless fabric, which allows network operators to dramatically improve broadband performance and quality of service, will continue to expand with the addition of fixed 5G technology at 28 GHz, increased federal spending for defense, and new premium versions of our software-as-a-service solutions. We remain very well positioned with customers for the next generation multi-gigabit fixed wireless infrastructure solutions featuring higher performance at affordable prices.”

Revenues of $61.9 million for the first quarter 2022 decreased $26.6 million year-over-year primarily as a result of lower Point-to-Multi-Point and Point-to-Point revenues due primarily to global supply and distribution constraints, including Chinese government COVID lockdowns, and slower demand from North American service providers, offsetting higher demand for enterprise Wi-Fi products. Revenues for the first quarter 2022 decreased by $16.8 million compared to $78.7

million for the fourth quarter 2021, primarily due to lower enterprise Wi-Fi and Point-to-Multi-Point revenues due to global supply and distribution constraints negatively impacting shipments of products.

GAAP gross margin for the first quarter 2022 was 47.1%, compared to 49.9% for the first quarter 2021, and 43.8% for the fourth quarter 2021. GAAP operating loss for the first quarter 2022 was $2.2 million, compared to operating income of $13.4 million for the first quarter 2021, and operating income of $2.9 million for the fourth quarter 2021. GAAP net loss for the first quarter 2022 was $1.6 million, or net loss of $0.06 per diluted share, compared to net income of $19.9 million, which includes a $7.6 million tax benefit, or net earnings of $0.70 per diluted share for the first quarter 2021, and net income of $1.4 million, or net earnings of $0.05 per diluted share for the fourth quarter 2021.

Non-GAAP gross margin for the first quarter 2022 was 47.8%, compared to 50.1% for the first quarter 2021, and 44.2% for the fourth quarter 2021. Non-GAAP operating income for the first quarter 2022 was $1.0 million, compared to $15.5 million for the first quarter 2021, and $5.8 million for the fourth quarter 2021. Non-GAAP net income for the first quarter 2022 was $0.3 million, or $0.01 per diluted share, compared to $11.7 million, or $0.41 per diluted share for the first quarter 2021, and $4.4 million, or $0.16 per diluted share, for the fourth quarter 2021. For the first quarter 2022, adjusted EBITDA was $1.9 million or 3.1% of revenues, compared to adjusted EBITDA of $16.5 million or 18.6% of revenues for the first quarter 2021, and $6.7 million or 8.6% of revenues for the fourth quarter 2021.

Cash used in operating activities was $19.2 million for the first quarter 2022, compared to $7.6 million cash used in operating activities for the first quarter 2021, and $5.6 million cash provided by operating activities for the fourth quarter 2021. Cash totaled $38.4 million as of March 31, 2022, $12.8 million lower than March 31, 2021, due primarily to the net debt paydown of $22.9 million, offset by earnings during the past year. The decrease in cash balance of $20.9 million from December 31, 2021, was primarily the result of a payment for 2021 annual variable compensation, and a $12.1 million decrease in accounts payable principally due to the timing of inventories payments.

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 2021 Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 24, 2022. 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.

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.

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. 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) nonrecurring legal expenses, (v) share-based compensation expense, (vi) secondary offering expenses, (vii) one-time acquisition costs, and (viii) 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 nonrecurring legal expenses since this is one-time in nature and does not reflect our ongoing operations. 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 and secondary offering 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, restructuring expenses and secondary offering expenses, nonrecurring legal expenses, write-down of debt issuance costs upon prepayment of debt, 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.

Nonrecurring legal expenses include settlements of existing or threatened litigation. Secondary offering expenses were incurred by Cambium Networks associated with the registration and sale in June 2021 of 2,000,000 ordinary shares held by Vector Capital and during December 2020 of 2,500,000 ordinary shares held by Vector Capital. Cambium Networks did not raise any additional capital in the offering and the expenses are excluded as not part of continuing operations.

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.

Restructuring expenses consist primarily 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 and impacts from the company's income tax valuation allowance initially recognized in the quarter ended June 30, 2019, and as reversed in the quarter ended March 31, 2021. 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.
