Ribbon Communications Inc. Q3 FY2026 earnings call

• Strong Q3 Momentum: The company delivered on expectations for significant sequential improvement in H2 2026, with revenue up 14% sequentially to $219 million and adjusted EBITDA more than doubling to $27 million.
• IP Optical Growth: Recorded a record third quarter with sales growing 17% sequentially. US sales increased over 50% compared to Q1, driven by strong IP routing shipments (up ~35%) and new Tier 2 service provider wins.
• Cloud & Edge Diversification: Verizon activity surged ~50% vs. H1 run rate as part of voice network modernization. New partnerships include TNS for rural providers and Salesforce/AWS for AI-powered contact centers.
• Geographic Expansion: Americas revenue grew 11% sequentially; Asia Pacific jumped 20% sequentially (driven by Vietnam >$10M project); EMEA rose 14% sequentially despite YoY decline due to prior year high base.
• Strategic Shifts: Focus on diversifying beyond traditional telecom into critical infrastructure, government/defense (e.g., federal agency win), and enterprise AI applications. Emphasis on combined IP and optical solutions for efficiency.

IP Optical Networks: Revenue was $96 million, representing a 17% sequential increase and a 5% year-over-year increase. This segment contributed approximately 43.8% to total consolidated revenue ($219 million). Cloud and Edge: Revenue was $123 million, reflecting an 11% sequential increase but a 1% year-over-year decrease. This segment contributed approximately 56.2% to total consolidated revenue.

• Q4 2026 Revenue: Expected range of $233 million to $247 million, implying continued sequential growth.
• Q4 2026 Adjusted EBITDA: Expected range of $40 million to $47 million, reflecting improved profitability driven primarily by the Cloud and Edge segment.
• Cost Assumptions: Guidance assumes approximately $2 million per quarter in increased product costs from higher component and logistics expenses, with potential offset via price increases in 2027.
• Supply Chain: Anticipates being supply-limited in Q4 due to high demand for key technologies, potentially pushing $5-$10 million in revenue into 2027.

• Supply Chain Constraints: Key components, including core silicon and optical line system technology, face significant lead times and availability issues, which may delay deliveries and push revenue to future quarters.
• Component Cost Inflation: Higher costs for components and logistics are expected to pressure margins, requiring potential pricing actions to mitigate.
• Working Capital Pressure: Accounts receivable increased significantly in Q3; cash flow from operations remained negative (-$14 million) due to timing of collections and invoicing cycles.
• Customer Concentration: Heavy reliance on major customers like Verizon; while activity is increasing, any slowdown in their migration programs could impact results.

Q: Analyst asked about Q4 margin drivers and IP Optical bookings, noting a lower book-to-bill ratio in Q3. / A: CEO explained that Q4 margin uplift is driven by Cloud and Edge software mix and fixed-cost professional services. He clarified that the Q3 book-to-bill of 0.82x was misleading because it reflected converting a large first-half backlog into revenue rather than weak demand, which actually grew 9% YoY.

Q: Analyst inquired about the composition of the 'large opportunities' funnel, specifically if they involve data centers or traditional carriers. / A: CEO clarified that the primary opportunities are with traditional Tier 1 telecom operators investing in fiber infrastructure for mobile backhaul and internet, which now also connects to data centers. He emphasized that Ribbon’s strength lies in serving these operators rather than building dedicated data center interconnects directly.

Q: Analyst asked about the significance of recent Tier 2 ISP wins and whether competitors’ focus on hyperscalers creates an opening for Ribbon. / A: CEO confirmed this is a strategic sweet spot. Tier 2 operators invest heavily in fiber and IP routing annually but often feel underserved. Ribbon differentiates itself by providing responsive, deep technical support and attention that larger competitors cannot offer to these mid-sized clients.

Q: Analyst questioned whether the trend of selling combined IP and optical solutions would persist and asked about margin differences between the two. / A: CEO stated that while every project varies, there is a clear trend toward combined solutions for capacity refreshes. He noted that current IP margins are lower due to aggregation routers, but expects the IP gross margin profile to strengthen over time as the portfolio evolves.
