Ribbon Communications Earnings Call Transcript Summary of Q1 2026
Ribbon reported Q1 2026 revenue of $163M, down 10% year-over-year, with non-GAAP gross margin of 45.8% and adjusted EBITDA of negative $8M. Performance was weighed by slower-than-normal early-year deployments (notably timing with certain U.S. Tier‑1 projects) while demand in India surprised to the upside (Bharat Airtel was >10% customer in the quarter). Bookings were healthy (consolidated book-to-bill 1.1x; IP Optical 1.5x), supporting management's view for a stronger second half. Management is deliberately retaining key services resources now (pressuring near-term margins) to be execution-ready for expected volume ramps. Key wins include multiple data-center interconnect and critical infrastructure projects across geographies; cloud-native SBC deployments (including AWS partnership) are progressing and the Acumen AI Ops platform is expected to go live with a lead customer later this quarter. Q2 guidance: revenue $185–$195M and adjusted EBITDA $9–$14M. Cash at quarter end was $70M, net leverage 2.9x, and CFO John Townsend is leaving with Rick Marmurek promoted to CFO.
