Achieved 18% sequential revenue growth driven by record IP Optical bookings and strong U.S. enterprise demand, despite a 19% sequential increase in Cloud & Edge product and services revenue.
IP Optical segment reached an all-time high in product and service bookings with a 1.6x book-to-bill ratio, resulting in a 60% year-to-date backlog increase.
Performance in Cloud & Edge was impacted by lower year-over-year revenue, but the company is working closely with Verizon to re-accelerate voice switch upgrades within their network to achieve higher velocity for the remainder of the year and into 2027.
Strategic partnership with Salesforce for 'Agentforce' validates a new market for AI-powered voice applications, which management expects will drive demand for cloud-native session border controllers.
U.S. enterprise growth was bolstered by major wins with Fortune 100 financial and energy firms, emphasizing a shift toward secure, carrier-grade voice and data infrastructure.
Management attributed the sequential gross margin improvement to better fixed cost absorption and a favorable geographic mix, specifically increased high-margin U.S. sales.

Outlook and Strategic Assumptions

Full-year 2026 revenue guidance was moderated to $810 million–$840 million, primarily due to slower-than-expected deployment velocity for U.S. Tier 1 voice modernization projects.
Management anticipates sequential revenue and earnings growth through Q3 and Q4, supported by the robust IP Optical backlog and a strong pipeline of mission-critical projects.
The guidance framework assumes approximately $2 million per quarter in increased component and logistics costs, which the company aims to partially offset through surgical price increases.
Supply chain limitations are expected to persist in the second half of 2026, particularly for core silicon and optical transceivers, given the high demand environment.
The company expects a 'strong setup' for 2027 as delayed Tier 1 modernization projects move into higher velocity deployment phases.

Risk Factors and Operational Context

Component cost inflation is now estimated at $5 million for the year, up from initial estimates of a few million dollars, impacting consolidated gross margin targets.
BEAD funding has been slow to materialize due to administrative friction and operator resistance, leading management to exclude significant BEAD-related revenue from the 2026 outlook.
Geopolitical dynamics have not disrupted ECI operations, though management remains vigilant regarding global supply chain stability.
The IP Optical segment remains EBITDA negative, with management focused on improving geographic mix and operational efficiency to reach breakeven.

Management identified core silicon, memory, and optical transceivers as the primary areas of inflationary pressure.
The company is using a 'surgical' approach to pass through costs, including reducing price guarantee timelines for hardware-integrated software sales.

Verizon's contribution and deployment velocity

Verizon remained a 10% plus customer in Q2 and is expected to maintain that status in the second half of the year as deployment rates re-accelerate.
The $25 million first-half revenue decline from Verizon accounts for a significant portion of the downward revision to full-year guidance.

Data Center Interconnect (DCI) market traction

DCI projects doubled sequentially in Q2 and now represent approximately 10% of IP Optical revenue.
Management sees a $50 million pipeline of incremental business over the next 12-18 months from new customers in this segment.

Enterprise edge and copper retirement opportunities

Ribbon is expanding its enterprise edge portfolio to help large organizations completely eliminate legacy copper and Sonnet infrastructure.
These products allow enterprises to preserve legacy TDM services while moving the demarcation point to a modern IP-based edge.
