Ribbon Announces $50 Million Share Repurchase Program

PLANO, Texas , June 3, 2025 /PRNewswire/ -- Ribbon Communications Inc. (Nasdaq: RBBN), a leading supplier of real-time communications technology and IP optical networking solutions, announced that its Board of Directors has authorized a program to repurchase up to $50 million of the Company's common stock, commencing June 5, 2025 and continuing through December 31, 2027.

"Today's announcement of our new share repurchase program reflects the Board of Director's confidence in our strategic plan and the significant improvement in our performance, highlighted by the record financial results in the fourth quarter 2024. Business with US Tier One Service Providers doubled in 2024 underpinned by a multi-year contract with Verizon to support modernizing their telecom voice infrastructure along with projects with other carriers. At the same time, business with Enterprise customers and U.S. Federal agencies has grown significantly. Overall, earnings increased by 30% in 2024 and were at the high end of our original guidance for the year," said Bruce McClelland, President and CEO of Ribbon Communications.  "The visibility in our business has improved significantly with positive book-to-bill and growing backlog, and we are focused on driving profitable growth and strong cash flow generation. This share repurchase program exemplifies our commitment to deliver value to our stockholders."

Ribbon Communications may purchase shares at management's discretion in the open market, in privately negotiated transactions, in transactions structured through investment banking institutions, or a combination of the foregoing. The Company may also, from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of its shares under this authorization. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, compliance with the Company's credit facility and general business and market conditions. The program may be modified, increased, suspended, or discontinued at any time. The share repurchase program will be funded with cash on hand or cash generated from operations.
