Credo Technology stock tumbled 21% on September 2 despite beating first-quarter earnings targets, as margin compression and cautious forward guidance overshadowed strong revenue growth driven by artificial intelligence data center demand.
The semiconductor connectivity company reported adjusted earnings per share of $1.20, topping analyst estimates of $1.17, and revenue of $479 million, exceeding the consensus expectation of $471.71 million. Non-GAAP net income surged 140% year-over-year to $236.3 million, while revenue climbed 114.7% from the year-ago quarter, reflecting robust demand for the company’s optical and copper interconnect solutions used in AI infrastructure.
Yet investors reacted sharply to the company’s deteriorating profitability metrics. Credo’s GAAP gross margin fell to 64.5% from 68.2% in the preceding quarter and 67.4% a year earlier. The company guided for even steeper margin pressure in the second quarter, projecting GAAP gross margin between 62.9% and 64.9%, signaling a further step-down that alarmed investors. The margin squeeze reflects the ramp of new product lines, including ZeroFlap optics and OmniConnect memory interconnect solutions, which carry lower initial margins as they scale.
Credo’s pattern of earnings beats followed by stock declines is not new. In June 2026, the company beat fourth-quarter earnings and revenue targets with a 157% year-over-year revenue surge and adjusted earnings of $1.16 per share, yet shares fell 10% to 12% in after-hours trading. That sell-off also centered on guidance that disappointed elevated market expectations, signaling the market’s focus on forward profitability rather than historical results.
The sell-off reflects a broader dynamic in semiconductor stocks, where earnings beats alone are no longer enough to drive gains. According to research cited in August 2026, among companies that beat consensus earnings per share estimates, roughly 45% to 50% still trade lower the next day. Analysts note that stocks can fall despite earnings beats when guidance or margin trends disappoint, and that forward guidance often drives post-earnings stock reactions more than the beat itself.
Credo’s second-quarter revenue guidance of $525 million to $535 million implies mid-single-digit sequential growth, a slowdown from the 9.6% quarter-over-quarter increase in Q1. The company maintained a non-GAAP gross margin guidance range of 67% to 69% for the second quarter, suggesting stabilization after the sequential decline, but the GAAP margin outlook of 62.9% to 64.9% signals continued pressure from product-mix shifts and integration costs.
The company’s Q1 results reflected strong AI data center momentum, with Bill Brennan, Credo’s president and CEO, noting that the company now spans connectivity solutions from millimeters to kilometers across optics and copper. Cash and short-term investments stood at $764.3 million, providing a strong balance sheet to fund operations and potential acquisitions as the company expands its product portfolio.
