Credo's post-earnings slide: valuation compresses but concentration risk persists

What happened

Credo shares plunged 20% on September 2 after fiscal Q1 FY27 results, despite revenue up 115% to $479 million, as the market balked at the optical outlook and dependence on two customers. A Seeking Alpha article argues the selloff is a buying opportunity, noting the stock's valuation has compressed to 22.5x earnings, management guides for >85% growth this fiscal year, and there is no imminent disruption between AEC and optical businesses. However, the company's own filings show that 71% of revenue comes from just two customers, over 90% of growth is still from AEC, and optical revenue from the DustPhotonics acquisition remains immaterial. The market's concerns about hyperscaler concentration (>60%) and potential CapEx slowdown post-FY2028 are valid even if the near-term demand environment stays strong. With the stock at $165.22, the risk-reward is only average: the price still prices in a successful optical ramp that has yet to appear in the numbers.

Implication

Investors should maintain a cautious stance; the stock's drop has improved valuation but not enough to eliminate concentration risk. The next few quarters will be critical: fiscal Q2 revenue must meet $525-535M guidance and non-GAAP gross margin stay 67-69%, but more importantly, the next 10-Q must show customer concentration declining and optical revenue becoming material. Until then, the stock remains a narrow AEC trade at a premium multiple, and a better entry near $145 or clear optical traction would be needed to upgrade from wait. The DustPhotonics acquisition adds strategic optionality but also integration risk, and its $1.25 billion price tag demands visible payback. Overall, the market's skepticism is understandable, and the burden of proof is on management to demonstrate diversification and optical revenue in the next two quarterly reports.

Thesis delta

No material change to the WAIT rating. The post-earnings selloff has compressed the valuation to a more reasonable level, but the core risks—customer concentration and unproven optical ramp—remain unresolved. The thesis still requires evidence of diversification and optical revenue becoming material before becoming constructive.
