Marvell Technology, a designer of custom chips for data centers, saw its shares drop about 8% in premarket trading on Friday after a cautious long-term forecast overshadowed a quarterly revenue beat and 37% year-over-year growth.
The company reported second-quarter revenue that topped Wall Street estimates, driven by demand for artificial intelligence infrastructure. Yet investors focused instead on Marvell’s fiscal 2028 outlook, which fell short of the growth targets many had built into the stock. The gap between strong current results and softer guidance drove the sell-off.
Much of the concern centered on the timing of revenue from a major AI partnership with Google. Analysts and shareholders had expected contributions from the custom silicon deal to arrive sooner, and questions over when that money would actually land dampened enthusiasm for otherwise healthy numbers.
For chip investors, the reaction fits a familiar pattern this year: companies posting real AI-driven gains still get punished when payoffs look further out than hoped. Similar unease pushed shares of Google and Tesla lower earlier this summer as markets questioned the timeline for returns on heavy AI spending.
Despite the drop, much of Wall Street stayed positive. Bank of America, UBS, Barclays, Wells Fargo and Citi all maintained bullish stances on the semiconductor designer, treating the decline as a reaction to expectations rather than a deterioration in the underlying business.
The bull case rests on Marvell’s position supplying custom accelerators and networking silicon to hyperscale cloud operators building out AI capacity. Those contracts tend to ramp over multiple quarters, meaning revenue that disappoints on timing can still materialize at scale later.
Behind the numbers, the episode reflects how tightly chip valuations are now tied to AI narratives. When a company grows revenue by more than a third and its stock still falls, the market is pricing not just performance but the pace of future delivery.
Marvell’s next task is to convert its design wins with large cloud customers into recognized revenue on a schedule that satisfies investors. How quickly the Google-linked business scales through fiscal 2027 and into 2028 will likely determine whether the analysts holding firm are proved right.
