Credo Raises Guidance as Optical Ramp Accelerates

Credo Technology reported fiscal Q4 2026 revenue of $437 million, up 157% year-over-year, with a non-GAAP gross margin of 68.3% and non-GAAP net income of $227 million, according to the company's earnings call, covered by GuruFocus/Yahoo Finance and separately by Seeking Alpha. Full fiscal-year 2026 revenue reached about $1.34 billion, up 206% year-over-year, with non-GAAP net income rising more than fivefold to $662 million. CFO Dan Fleming and CEO Bill Brennan guided fiscal 2027 revenue growth above 80% year-over-year, driven by the company's optical portfolio, DSPs, silicon photonics PICs, and ZeroFlap Optics, following the Dust Photonics acquisition, with each segment expected to exceed $100 million and combined optical revenue exceeding $600 million. Seeking Alpha's coverage additionally cites $1.4 billion in cash with zero debt and upgrades CRDO to a BUY rating; that cash figure comes from Seeking Alpha's reporting and was not independently confirmed in the earnings-call materials reviewed here.

On the earnings call, Fleming said first-half fiscal 2027 growth will be driven mainly by Credo's existing AEC (active electrical cable) portfolio, with the optical-portfolio inflection concentrated in the second half. Brennan told analysts all three optical product lines are expected to grow more than 80% year-over-year, without specifying which will lead. This two-stage ramp, steady-state copper/AEC growth followed by an optical inflection tied to a specific acquisition, mirrors how other AI-networking suppliers have described capacity build-outs tied to hyperscaler qualification cycles.

For infrastructure planners and AI-networking vendors, Credo's own caveats are more decision-useful than the guidance headline: management flagged persistent supply-chain tightness for ZeroFlap Optics and AECs, uncertain timing on the 800G-to-1.6T bandwidth transition, and non-GAAP operating expenses rising roughly 50% year-over-year to support the ramp. Teams evaluating optical-interconnect suppliers should track whether the guided second-half optical inflection materializes on schedule, since a slip would be a leading indicator of broader AI data-center supply constraints, not just a single-vendor issue.

Watch Credo's fiscal Q1 2027 results for early signs of the guided ramp, further disclosure on customer qualification for the three optical product lines, and any updates on the 800G-to-1.6T transition timeline that management flagged as uncertain.
