Ribbon Communications Inc. filed its annual report describing a global communications technology business focused on secure voice, data and high-bandwidth networking for service providers and enterprises. The company operates two main segments: Cloud and Edge, and IP Optical Networks, both benefiting from trends like 5G, fiber build‑outs and AI‑driven automation.
Ribbon highlights its mission to deliver scalable, cloud‑centric networking solutions and notes customer concentration, with Verizon accounting for about 17% of 2025 revenue and the top five customers 41%. It reports an aggregate market value of non‑affiliate common stock of approximately $299.5 million and 175,604,524 shares outstanding.
The report discusses competitive pressures from large telecom vendors, supply‑chain and geopolitical risks, and a broad risk factor set including revenue volatility, restructuring, credit exposure, cybersecurity (including a 2025 nation‑state intrusion that was contained and remediated), regulatory obligations and AI‑related uncertainties. Ribbon also emphasizes ESG initiatives, a global workforce of 3,080 employees, low voluntary turnover of 5.5% in 2025, active learning and development programs, and community engagement with about 5,000 volunteer hours.
