Plano, TX - Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real-time communications software and IP optical transport solutions to service providers, enterprises, and critical infrastructure sectors, today announced its financial results for the third quarter of 2021.

For the first nine months of 2021, sales increased by 2%, Adjusted EBITDA increased 14% and Non-GAAP diluted earnings per share increased 29% versus 2020 (GAAP loss per share increased by $0.291). Revenue for the third quarter of 2021 was $210 million, impacted by approximately $9.5 million related to supply chain constraints in the quarter.

"We're excited by our recent IP Optical Networks wins and growth prospects as our funnel of opportunities strengthen and benefit from the breadth of existing Ribbon relationships with customers," noted Bruce McClelland, President and Chief Executive Officer of Ribbon Communications. "We believe these customer wins, along with accelerating investments in fiber networks and 5G technology, position Ribbon for strong growth in 2022 and beyond. While revenues this quarter were impacted by supply chain constraints, we believe our IP Optical product book to revenue ratio of 1.17 times demonstrates growing demand."


Financial Highlights1, 2

The following table summarizes the consolidated financial highlights for the three and nine months ended September 30, 2021 and 2020 (in millions, except per share amounts).

Three months ended Nine months ended
September 30, September 30,
2021 2020 2021 2020
GAAP Revenue $ 210 $ 231 $ 614 $ 600
GAAP Net income (loss) $ (59 ) $ 6 $ (81 ) $ (35 )
Non-GAAP Net income $ 16 $ 22 $ 48 $ 34
GAAP Income (loss) per share $ (0.40 ) $ 0.04 $ (0.55 ) $ (0.26 )
Weighted average shares outstanding for GAAP income (loss) per share 148 152 147 137
Non-GAAP diluted earnings per share $ 0.11 $ 0.14 $ 0.31 $ 0.24
Diluted weighted average shares outstanding for Non-GAAP diluted earnings per share 154 152 155 141
Non-GAAP Adjusted EBITDA $ 32 $ 43 $ 94 $ 82

1 GAAP Net income and GAAP Diluted earnings per share for the three months and nine months ended September 30, 2021 include $0.9 million and $3.6 million, respectively, of paid-in-kind interest income earned on the convertible debentures received as consideration from the sale of our Kandy Communications business to American Virtual Cloud Technologies ("AVCT"). The interest income is included in Interest expense, net, and the remeasurement losses and gains are included in Other (expense) income, net. The remeasurement (gains) losses were calculated using valuation methods in accordance with accounting guidance. Fluctuations in AVCT's stock price will impact the future amounts that are recorded in Other (expense) income, net, and could materially impact the Company's quarterly results. Year-to-date GAAP EPS was negatively impacted by $0.46 attributable to the remeasurement loss of our investment in AVCT.

Cash, cash equivalents and restricted cash was $104 million at September 30, 2021, compared with $115 million at June 30, 2021, due in part to an increase of $16 million in accounts receivable. The GAAP Net loss of $59 million in the third quarter of 2021 includes a $56 million non-cash loss associated with the quarterly mark-to-market of our investment in AVCT from the sale of our Kandy Communications business.

"Our Cloud & Edge business continued to generate strong profitability in the quarter, while we expand our investment in our IP Optical Networks portfolio to address the growing tier 1 service provider opportunity pipeline. We believe this investment will generate future returns as we execute on our cross-sell strategy. We remain confident in the Company's direction as we navigate the impact of supply chain constraints," said Mick Lopez, Chief Financial Officer of Ribbon Communications.

All statements other than statements of historical facts contained in this release, including without limitation statements regarding, projected financial results for the fourth quarter 2021 and beyond, sales trends, and plans and objectives of management for future operations are forward-looking statements. Without limiting the foregoing, the words "believes", "estimates", "expects", "expectations", "intends", "may", "plans", "projects" and other similar language, whether in the negative or affirmative, are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Our actual results may differ materially from those contemplated in these forward-looking statements due to various risks, uncertainties and other important factors, including, among others, risks related to supply chain disruptions resulting from component availability and/or geopolitical instabilities and disputes; risks related to the continuing COVID-19 pandemic, including delays in customer deployments as a result of rises in cases; risks that we will not realize estimated cost savings and/or anticipated benefits from the acquisition of ECI; failure to realize anticipated benefits from the sale of our Kandy Communications business ("Kandy") or declines in the value of our ongoing investment in AVCT, the purchaser of the Kandy Communications business; unpredictable fluctuations in quarterly revenue and operating results; risks related to cybersecurity and data intrusion; failure to compete successfully against telecommunications equipment and networking companies; failure to grow our customer base or generate recurring business from our existing customers; credit risks; the timing of customer purchasing decisions and our recognition of revenues; macroeconomic conditions; the impact of restructuring and cost-containment activities; litigation; market acceptance of our products and services; rapid technological and market change; our ability to protect our intellectual property rights and obtain necessary licenses; our ability to maintain partner, reseller, distribution and vendor support and supply relationships; the potential for defects in our products; risks related to the terms of our credit agreement; higher risks in international operations and markets; increases in tariffs, trade restrictions or taxes on our products; currency fluctuations; and failure or circumvention of our controls and procedures.

These factors are not intended to be an all-encompassing list of risks and uncertainties that may affect our business and results from operations. Additional information regarding these and other factors can be found in our reports filed with the Securities and Exchange Commission, including our Form 10-K for the year ended December 31, 2020. In providing forward-looking statements, the Company expressly disclaims any obligation to update these statements publicly or otherwise, whether as a result of new information, future events or otherwise, except as required by law.

Discussion of Non-GAAP Financial Measures

Our management uses several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, making operating decisions, planning and forecasting future periods, and determining payments under compensation programs. We consider the use of non-GAAP financial measures helpful in assessing the core performance of our continuing operations and when planning and forecasting future periods. Our annual financial plan is prepared on a non-GAAP basis and is approved by our board of directors. In addition, budgeting and forecasting for revenue and expenses are conducted on a non-GAAP basis and actual results on a non-GAAP basis are assessed against the annual financial plan. By continuing operations, we mean the ongoing results of our business adjusted for certain expenses and credits, as described below. We believe that providing non-GAAP information to investors will allow investors to view the financial results in the way our management views them and helps investors to better understand our core financial and operating performance and evaluate the efficacy of the methodology and information used by our management to evaluate and measure such performance.

While our management uses non-GAAP financial measures as tools to enhance their understanding of certain aspects of our financial performance, our management does not consider these measures to be a substitute for, or superior to, GAAP measures. In addition, our presentations of these measures may not be comparable to similarly titled measures used by other companies. These non-GAAP financial measures should not be considered alternatives for, or in isolation from, the financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures. In particular, many of the adjustments to our financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future.

3

Acquisition-Related Inventory Adjustment

Acquisition-related inventory adjustment amounts are inconsistent in frequency and amount and are significantly impacted by the then-current market prices of such inventory items. We believe that excluding non-cash inventory adjustments arising from acquisitions facilitates the comparison of our financial results to our historical operating results and to other companies in our industry as if the inventory had been acquired by us through our normal channels rather than in connection with our acquired businesses.

Stock-Based Compensation

The expense related to stock-based awards is generally not controllable in the short-term and can vary significantly based on the timing, size and nature of awards granted. We believe that presenting non-GAAP operating results that exclude stock-based compensation provides investors with visibility and insight into our management's method of analysis and our core operating performance.

Amortization of Acquired Intangible Assets

Amortization amounts are inconsistent in frequency and amount and are significantly impacted by the timing and size of acquisitions. We believe that excluding non-cash amortization of intangible assets facilitates the comparison of our financial results to our historical operating results and to other companies in our industry as if the acquired intangible assets had been developed internally rather than acquired.

Litigation Costs

We have been involved in litigation with a former GENBAND business partner and have reached settlement with the other party. We exclude the costs of such litigation because we believe such costs are not part of our core business or ongoing operations.

Acquisition-, Disposal- and Integration-Related Expense

We consider certain acquisition-, disposal- and integration-related costs to be unrelated to the organic continuing operations of our acquired businesses and the Company, and such costs are generally not relevant to assessing or estimating the long-term performance of the acquired assets. We exclude such acquisition-, disposal- and integration-related costs to allow more accurate comparisons of our financial results to our historical operations and the financial results of less acquisitive peer companies and allows management and investors to consider the ongoing operations of the business both with and without such expenses.

Restructuring and Related Expense

We have recorded restructuring and related expense to streamline operations and reduce operating costs by closing and consolidating certain facilities and reducing our worldwide workforce. We believe that excluding restructuring and related expense facilitates the comparison of our financial results to our historical operating results and to other companies in our industry, as there are no future revenue streams or other benefits associated with these costs.

Gain on Sale of Business

On May 12, 2021, we sold our Qualitech business, which we had acquired as part of the ECI Acquisition, to Hermon Laboratories, Ltd. As consideration, we received $2.9 million of cash and recorded a gain on the sale of $2.8 million. We exclude this gain because we believe that such gains are not part of our core business or ongoing operations.

4

Interest Income on Debentures

We recorded paid-in-kind interest income on the debentures received as consideration from the sale of our Kandy Communications business (the "Debentures"), which increased their fair value. We exclude this interest income because we believe that such a gain is not part of our core business or ongoing operations.

Decrease (Increase) in Fair Value of Investments

We calculate the fair values of the Debentures and the Warrants received as consideration from the sale of our Kandy Communications business (the "Warrants") (prior to September 8, 2021) and the shares of AVCT common stock and Warrants (effective September 8, 2021) at each quarter-end and record any adjustments to their fair values in Other (expense) income, net. We exclude these and any subsequent gains and losses from the change in fair value of this investment because we believe that such gains or losses are not part of our core business or ongoing operations.

Tax Effect of Non-GAAP Adjustments

Non-GAAP income tax expense is presented based on an estimated tax rate applied against forecasted annual non-GAAP income. Non-GAAP income tax expense assumes no available net operating losses or valuation allowances for the U.S. because of reporting significant cumulative non-GAAP income over the past several years. We are reporting our non-GAAP quarterly income taxes by computing an annual rate for the Company and applying that single rate (rather than multiple rates by jurisdiction) to our consolidated quarterly results. We expect that this methodology will provide a consistent rate throughout the year and allow investors to better understand the impact of income taxes on our results. Due to the methodology applied to our estimated annual tax rate, our estimated tax rate on non-GAAP income will differ from our GAAP tax rate and from our actual tax liabilities.

Adjusted EBITDA

We use Adjusted EBITDA as a supplemental measure to review and assess our performance. We calculate Adjusted EBITDA by excluding from Income (loss) from operations: depreciation; amortization of acquired intangible assets; stock-based compensation; acquisition-related inventory adjustments; certain litigation costs; acquisition-, disposal- and integration-related expense; and restructuring and related expense. In general, we exclude the expenses that we consider to be non-cash and/or not part of our ongoing operations. We may exclude other items in the future that have those characteristics. Adjusted EBITDA is a non-GAAP financial measure that is used by our investing community for comparative and valuation purposes. We disclose this metric to support and facilitate our dialogue with research analysts and investors. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.
