Cerebras Stock Drops 20% After Margin Guidance Revision
Original: Cerebras stock plunges after earnings as CEO says margin outlook was misunderstood
Why This Matters
Margin guidance shifts significantly impact investor sentiment in semiconductor and AI hardware sectors, affecting capital allocation decisions.
Cerebras Systems shares fell nearly 20% on June 24, 2026, despite beating Q1 earnings expectations. The AI chipmaker cut full-year gross margin guidance to 38-41%, down from 47% in Q1, citing equipment rental arrangements with a major customer.
Cerebras Systems experienced a significant stock decline following its first earnings report as a publicly traded company. Although the chipmaker reported better-than-expected Q1 results with revenue reaching $193 million, up 94% year-over-year, and net loss narrowing to $14 million from $23.9 million in the prior year, investors reacted negatively to revised margin guidance. The company forecast full-year gross margins of 38% to 41%, substantially lower than the 47% margin achieved in the first quarter. CEO Andrew Feldman stated on CNBC that the margin outlook had been misunderstood by investors. Cerebras explained during its earnings call that it decided to make capacity available sooner by temporarily renting its own systems back from an existing major customer while building out its own data center infrastructure. This arrangement was identified as the primary factor impacting profit margins for the year. The stock reached nearly its IPO price by Wednesday, marking a new low for the publicly traded company.
