- What they said
- Harmonic reported a strong Q1 2026 with broadband revenue up 43% year-over-year to $121.7M, rest-of-market revenue up 78% YoY, record backlog and deferred revenue (bookings strong, backlog up 87% YoY), and EPS and operating profit above guidance. Management raised full-year broadband revenue guidance to $475M-$495M from $440M-$480M and highlighted continued momentum in DOCSIS 4.0 ramps, fiber growth, and an expanding intelligence layer. The company is proceeding with the sale of its video business (classified as held for sale) expected to close in Q2, repurchased $43M of stock, and emphasized diversification of customer base and geographic expansion (some wins in Taiwan, Europe, Latin America). Management noted supply chain headwinds (memory ~$6M net impact to H2 margins, potential constraints in CPUs, PCBs, switches/servers) and macro uncertainty (Middle East) and said they are being prudent in guidance. Management expressed confidence in demand and execution while being cautious on supply-side risks; Q&A was direct and management appeared measured and confident.
- Guidance
- Raised full-year 2026 broadband revenue guidance to $475 million - $495 million (previously $440M - $480M). Q1 results exceeded guidance (broadband revenue $121.7M vs guidance $100M-$105M; EPS $0.17 vs guidance $0.11-$0.12). No detailed segment-level guidance for fiber or rest-of-market provided; management remains conservative on full-year profile due to supply-chain and macro uncertainties.
- Risks flagged
- Supply chain constraints (memory causing ~ $6M net impact in second half margins; potential constraints in CPUs, PCBs, aluminum, switches, servers); macro/geopolitical uncertainty (Middle East); transaction and customary closing conditions for sale of video business; availability of third-party components may delay customer deployments; potential margin pressure from product ramps and mix shifts (software mix, new product ramp margins).
