Third Quarter 2025 Highlights

Financial Highlights¹:

Revenue was $215 million, compared to $210 million for the third quarter of 2024 GAAP Operating Income was $3 million, compared to a loss of $1 million for the third quarter of 2024 Non-GAAP Adjusted EBITDA was $29 million, compared to $30 million for the third quarter of 2024 GAAP Gross Margin was 50.1%, compared to 52.1% for the third quarter of 2024 Non-GAAP Gross Margin was 52.6%, compared to 55.3% for the third quarter of 2024

“Ribbon delivered solid results in the third quarter, with sales growing 2% year over year, an increase of 6% year to date. IP Optical Networks sales grew 11% year over year in the quarter with strong growth in EMEA and India. Cloud & Edge sales year to date have increased more than 8% with sales to Global Service Providers continuing to grow. The recent U.S. Federal Government shut down had a minor impact on our Cloud & Edge third quarter results and creates a near-term timing issue on new purchases, but related voice modernization projects are continuing to progress,” stated Bruce McClelland, President and Chief Executive Officer of Ribbon Communications. “More broadly, we believe that our momentum remains strong as evidenced by the expanding number of customers initiating Network Transformation programs and continued growth in our IP Optical Networks segment.”

Mr. McClelland continued, “I am also excited about our innovation pipeline. During the third quarter, we announced the launch and initial deployment of our Acumen AIOps platform with a leading U.S. service provider. Acumen is a powerful new AIOps and automation platform designed to help service providers and enterprises navigate the complexities of today's challenging operational environment and accelerate their transition to autonomous networks. Beyond AIOps, our Cloud & Edge portfolio is becoming increasingly strategic to our customers as they bring voice-enabled Agentic AI capabilities to their offerings including some of the largest global technology and software companies.”

John Townsend, Chief Financial Officer of Ribbon Communications, remarked, “Our financial performance in the third quarter of 2025 was in line with our guidance range, supported by solid growth and positive adjusted EBITDA contribution in our IP Optical Networks segment. We also continued to demonstrate strong discipline with operating expenses lower year over year despite foreign exchange headwinds of approximately $3 million. Cash flow from operations was $26 million and our closing cash balance was $77 million, up $14 million from the second quarter of 2025, resulting in a net debt leverage ratio of 2.2 times at quarter end.”
