Ribbon Communications posted a 15% year-over-year increase in second-quarter 2025 revenue, reaching $221 million, fueled by strong demand in North America and key wins in voice transformation and IP optical networking. GAAP operating income reached $4 million, reversing a loss from the same period last year. Adjusted EBITDA jumped 47% to $32 million, hitting the upper end of company guidance.
The company saw momentum across both Service Provider and Enterprise verticals, with optical network upgrades gaining traction in India and North America, including deployments supporting fiber and mobile expansion. While GAAP gross margin dipped to 49.6% from 50.8% a year ago, Ribbon maintained solid profitability, with non-GAAP gross margin at 52.1%. Net income on a GAAP basis remained negative at -$11 million, although significantly improved from the prior year’s -$17 million.
In Q2, Ribbon unveiled a $50 million share repurchase program and reported a cash balance of $62 million. The company anticipates improved cash flow in the second half of the year due to favorable corporate tax changes in the newly passed U.S. spending bill. For Q3 2025, Ribbon forecasts revenue between $213 million and $227 million, with non-GAAP gross margin between 53.5% and 54.0% and adjusted EBITDA between $28 million and $34 million.
