“I am very pleased with our strong financial performance in the second quarter with both revenue and earnings exceeding our growth projections, resulting in a successful first half of the year. Demand in the North American market was strong across both Service Provider and Enterprise market verticals as we continue to win the largest industry voice transformation opportunities. And we had good momentum in our IP Optical business in India and North America this quarter supporting fiber and mobile network expansion,” stated Bruce McClelland, President and Chief Executive Officer of Ribbon Communications. “Looking ahead, the demand picture remains robust with good visibility, and we continue to anticipate a seasonally stronger second half of the year.”

John Townsend, Chief Financial Officer, added, “It was great to see our business momentum reflected in our second quarter results. Revenue increased 15% year over year to $221 million, exceeding guidance, and Adjusted EBITDA increased 47% year over year to $32 million, at the top end of our guidance. In the quarter, we announced a new stock repurchase program and expect to use a portion of our free cash flow over the next several years to repurchase up to $50 million of our common stock. Our cash position remained solid, closing the quarter at $62 million including $2.3 million of stock repurchases. In addition, the new U.S. spending bill recently approved by Congress includes corporate tax changes that are expected to result in lower cash tax payments in the second half, which should further improve our cash flow this year.”

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 litigation where Ribbon is the defendant (as described in the Company’s Commitments and Contingencies footnotes in its Form 10-Qs and Form 10-Ks filed with the SEC, 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 are not within its control. Accordingly, the Company believes that excluding 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. In the second quarter of 2025, the Company recorded $3.9 million of expense for legal and professional fees associated with contemplated corporate development activities. 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.
