Plano, TX – Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real time communications technology and IP optical networking solutions to many of the world’s largest service providers, enterprises, and critical infrastructure operators to modernize and protect their networks, today announced its financial results for the second quarter of 2024.

Revenue for the second quarter of 2024 was $193 million, compared to $211 for the second quarter of 2023 and $180 million for the first quarter of 2024. First half 2024 GAAP Loss from Operations improved $26 million year over year to ($15 million), and Non-GAAP Adjusted EBITDA improved $13 million, or 65%, to $33 million. GAAP and Non-GAAP Gross Margin for the second quarter improved 260 and 240 basis points year over year, respectively.

“Earnings increased significantly in the first half of 2024 with Adjusted EBITDA increasing 65% year over year despite lower sales. The improvement in profitability was driven by higher gross margins and lower operating expenses year over year. Revenue in the second quarter was impacted by a large U.S. Federal deal that was delayed to the third quarter. Sales were also lower as we suspended product shipments into Eastern Europe due to the extended war in Ukraine and increased complexities of operating in the region,” stated Bruce McClelland, President and Chief Executive Officer of Ribbon Communications.

Mr. McClelland added, “We continue to project a strong second half of 2024 as we ramp the recently announced Verizon Voice Network modernization program and anticipate strong growth in several other areas such as Enterprise, U.S. Rural Broadband, Europe, and India. Recent changes in the competitive landscape also present an opportunity for further share expansion. However, we have adjusted our full year 2024 guidance slightly to reflect a more conservative outlook for the Eastern European region for the rest of the year.”

“During the second quarter of 2024, we completed the refinancing of our capital structure with a $385 million five-year senior secured credit facility that provides us greater liquidity with less restrictions. Our new strategic banking group relationship with HPS Investment Partners, LLC and WhiteHorse Capital Management, LLC will also give us opportunities to support our future growth needs,” said Mick Lopez, Chief Financial Officer of Ribbon Communications. “Additionally, we continue to improve our operations, driving a 240 basis point improvement year over year in gross margins and a $4 million reduction in expenses, resulting in the lowest level of operating expenses since the ECI acquisition in 2020.”

Business Outlook1 

For the third quarter of 2024, the Company expects continued sequential growth in both of our businesses with revenue in a range of $205 million to $220 million. Non-GAAP gross margin is projected in a range of 53% to 53.5%. Adjusted EBITDA is projected in a range of $25 million to $30 million.

The Company has also adjusted full-year 2024 targets and now expects revenue in a range of $830 million to $850 million, non-GAAP gross margin in a range of 54% to 54.5%, and Adjusted EBITDA in a range of $105 million to $115 million.

The Company’s outlook is based on current indications for its business, which are subject to change.

Forward-looking statements are based on the Company’s current expectations and assumptions regarding its 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. 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, the effects of geopolitical instabilities and wars, including in Israel and Ukraine (and the impact of sanctions and trade restrictions imposed as a result thereof); unpredictable fluctuations in quarterly revenue and operating results; increases in tariffs, trade restrictions or taxes on the Company’s products; the impact of restructuring and cost-containment activities; operational disruptions at facilities located in Israel including as a result of military call-ups of the Company’s employees in Israel, closure of the offices there or the temporary or long-term closure of contract manufacturing in the region; the potential impact of litigation; risks related to supply chain disruptions, including as a result of component availability; risks resulting from higher interests rates and continued inflationary pressures; risks related to cybersecurity and data intrusion; failure to compete successfully against telecommunications equipment and networking companies; failure to grow the Company’s customer base or generate recurring business from existing customers; credit risks; the timing of customer purchasing decisions and the Company’s recognition of revenues; macroeconomic conditions, including inflation; market acceptance of the Company’s products and services; rapid technological and market change; the ability to protect Company intellectual property rights and obtain necessary licenses; the ability to maintain partner, reseller, distribution and vendor support and supply relationships; the potential for defects in the Company’s products; and currency fluctuations.

These factors are not intended to be an all-encompassing list of risks and uncertainties that may affect the Company's business and results from operations. Additional information regarding these and other factors can be found in the Company's reports filed with the Securities and Exchange Commission, including, without limitation, its Form 10-K for the year ended December 31, 2023 and its Form 10-Q for the quarter ended March 31, 2024. 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 

The Company’s management uses several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of its business, making operating decisions, planning and forecasting future periods, and determining payments under compensation programs. The Company considers the use of non-GAAP financial measures helpful in assessing the core performance of its continuing operations and when planning and forecasting future periods. The Company’s annual financial plan is prepared on a non-GAAP basis and is approved by its 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. The Company defines continuing operations as the ongoing results of its business adjusted for certain expenses and credits, as described below. The Company believes that providing non-GAAP information to investors allows them to view the Company’s financial results in the way its management views them and helps investors to better understand the Company’s core financial and operating performance and evaluate the efficacy of the methodology and information used by its management to evaluate and measure such performance.

While the Company’s management uses non-GAAP financial measures as tools to enhance its understanding of certain aspects of the Company’s financial performance, management does not consider these measures to be a substitute for, or superior to, GAAP measures. In addition, the Company’s 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 the Company’s financial measures reflect the exclusion of items that are recurring and will be reflected in its financial results for the foreseeable future.

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. The Company believes that presenting non-GAAP operating results that exclude stock-based compensation provides investors with visibility and insight into its management’s method of analysis and its core operating performance.

Amortization of Acquired Technology (including software licenses); Amortization of Acquired Intangible Assets 

Amortization amounts are inconsistent in frequency and amount and are significantly impacted by the timing and size of acquisitions. Amortization of acquired technology is reported separately within Cost of revenue and Amortization of acquired intangible assets is reported separately within Operating expenses. These items are reported collectively as Amortization of acquired intangible assets in the accompanying reconciliations of non-GAAP and GAAP financial measures. The Company believes that excluding non-cash amortization of these intangible assets facilitates the comparison of its financial results to its historical operating results and to other companies in its industry as if the acquired intangible assets had been developed internally rather than acquired.

Litigation Costs

In connection with certain ongoing contract litigation where Ribbon is the defendant (as described in Note 26 to the Company’s Consolidated Financial Statements included in its Annual Report on Form 10-K for the year ended December 31, 2023), the Company has incurred litigation costs beginning in 2023. These costs are included as a component of general and administrative expense. The Company believes that such costs are not part of its core business or ongoing operations, are unplanned and generally not within its control. Accordingly, the Company believes that excluding the litigation costs related to these specific legal matters facilitates the comparison of the Company’s financial results to its historical operating results and to other companies in its industry.

Acquisition-, Disposal- and Integration-Related 

The Company considers certain acquisition-, disposal- and integration-related costs to be unrelated to the organic continuing operations of the Company and its acquired businesses. Such costs are generally not relevant to assessing or estimating the long-term performance of the acquired assets. The Company excludes such acquisition-, disposal- and integration-related costs to allow more accurate comparisons of its financial results to its 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 

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

Preferred Stock and Warrant Liability Mark-to-Market Adjustment 

The Company recorded adjustments to the fair value of its Series A Preferred Stock and Warrants to purchase shares of the Company’s common stock in Other (expense) income, net. Both of these instruments were issued in March 2023 in connection with the Company’s private placement and have been classified as liabilities and marked to market each reporting period until the Series A Preferred Stock was fully redeemed on June 25, 2024. The Warrant liability remains outstanding and will continue to be marked to market each reporting period. The Company excluded these gains and losses from the change in the fair value of these liabilities because it believes that such gains or losses were not part of its core business or ongoing operations.

Tax Effect of Non-GAAP Adjustments 

The Non-GAAP income tax provision is presented based on an estimated tax rate applied against forecasted annual non-GAAP income. The Non-GAAP income tax provision 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. The Company is reporting its 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 its consolidated quarterly results. The Company expects that this methodology will provide a consistent rate throughout the year and allow investors to better understand the impact of income taxes on its results. Due to the methodology applied to its estimated annual tax rate, the Company’s estimated tax rate on non-GAAP income will differ from its GAAP tax rate and from its actual tax liabilities.

Adjusted EBITDA 

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