AI Brief

Q2 FY26 earnings call · Jul 28, 2026
Q2 FY26

TL;DR. Ribbon reported a Q2 with revenue of $192M (+18% sequentially) and Adjusted EBITDA of $12M, both above guidance midpoints, driven by a record IP optical bookings quarter and a new Salesforce Agentforce partnership, but lowered full-year 2026 outlook due to slower-than-expected U.S. Tier 1 voice modernization deployments.

Bullish
  • + Record IP optical bookings quarter with 1.6x book-to-bill and backlog up 60% year-to-date, including data center interconnect wins
  • + New strategic Salesforce Agentforce Contact Center partnership validates cloud-native AI voice market opportunity
  • + Defense revenue increased nearly 60% sequentially and year-over-year with new Network in a Box product for rugged environments
  • + Total enterprise sales increased 42% sequentially with diversified pipeline across energy, transportation, and government
  • + Q3 2026 guidance of $215-$230M revenue and $26-$31M Adjusted EBITDA implies continued sequential growth
Bearish
  • Lowered full-year 2026 revenue guidance to $810-$840M and Adjusted EBITDA to $78-$88M due to slower voice modernization
  • Cloud and edge revenue down 19% year-over-year on lower Verizon sales following prior-year record deployments
  • GAAP net loss of $27M in Q2; non-GAAP net loss of $5M and non-GAAP diluted loss per share of $0.03
