Backlog Increased 35% on Growing Service Provider Demand

Federal and Enterprise Deal Timing Affected 1Q25 Results but Delivering in 2Q

PLANO, Texas, April 29, 2025 -- Ribbon Communications Inc. (Nasdaq: RBBN), a leading supplier of real-time communications technology and IP optical networking solutions, today announced its financial results for the first quarter of 2025. Ribbon Communications is dedicated to assisting the world's largest service providers, enterprises, and critical infrastructure operators in modernizing and safeguarding their networks and services.

First Quarter 2025 Highlights

Financial Highlights¹:

  • Revenue was $181 million, compared to $180 million for the first quarter of 2024
  • GAAP Gross Margin was 45.4%, compared to 51.2% for the first quarter of 2024
  • Non-GAAP Gross Margin was 48.6%, compared to 55.1% for the first quarter of 2024
  • GAAP Operating Loss was ($20) million, compared to ($13) million for the first quarter of 2024
  • Non-GAAP Adjusted EBITDA was $6 million, compared to $12 million for the first quarter of 2024

"We continue to expect a strong first half for 2025 with sales projected to increase 5-8% year over year, overcoming the reduction in Eastern Europe revenue that began in the second quarter of 2024. In the first quarter, sales to Service Providers increased more than 10% year over year driven by a broad-based focus on Network Modernization," stated Bruce McClelland, President and Chief Executive Officer of Ribbon Communications. "Sales in the quarter were lower than expected due to timing of two key Federal and Enterprise deals which we are already fulfilling and are included in our second quarter. Bookings were once again very solid, and backlog is up 35% from the same point last year giving us improved visibility and confidence in the year."

John Townsend, Chief Financial Officer, added, "We expect gross margins to return to normal levels as product and regional mix improve in the second quarter and the rest of the year. I am particularly pleased with the disciplined approach to cost and cash management that we demonstrated in the first quarter."
