Shares shifted as Marvell Technology slid 5.1% to $232.30 on Oct. 22, extending a bruising stretch that has seen the stock fall roughly 19% from its Oct. 6 peak near $301. The pullback arrived despite a quarter that, on paper, was flawless — and it spotlights an uncomfortable truth about one of the hottest AI chip names: when a stock already prices in years of perfect execution, even good news can disappoint.

  • Record Results Still Weren't Enough for a Stock Trading at ~77× Earnings. Q2 revenue hit a record $2.739 billion, up 37% year-over-year and $39 million above guidance.

Non-GAAP earnings of $0.94 per share beat estimates and rose 40% from a year ago. Yet the stock trades at a P/E of roughly 78.8×, compared with a semiconductor sector average near 45× — meaning investors are already paying for results Marvell has not yet delivered. Any ambiguity about when growth arrives punishes the stock immediately.

  • The Google Deal Is Massive, But Back-Loaded. Marvell's expanded partnership with Google covers custom AI accelerators, storage controllers, and networking chips tied to Google's AI chip infrastructure.

Full vesting of associated share warrants corresponds to $120 billion in cumulative custom-product revenue, divided into 240 tranches of $500 million each. The catch: custom revenue is expected to more than double in fiscal 2028, with the Google agreement having "its largest impact in fiscal 2029 and beyond." That is two to three years away — an eternity for a stock priced this richly.

  • Guidance Was Raised Aggressively, Raising the Bar Even Higher. Marvell now expects fiscal 2027 revenue of roughly $12 billion, up from $11.5 billion previously, and fiscal 2028 revenue of approximately $18 billion.

The company generated $9.45 billion over the trailing twelve months; meeting the outlook requires more than doubling sales by fiscal 2028. Any slip in AI spending or delays in Google's custom-chip ramp would leave Marvell chasing its own promises.

  • A Broader AI Spending Scare Adds Fuel to the Fire. MRVL has returned 216% over the past twelve months, and on Oct. 6, management unveiled fiscal 2031 revenue targets of $70–$90 billion. But the stock is now being weighed down by renewed concern about AI spending and elevated valuations across the technology sector.

Marvell fell 55% during the 2025 tariff shock — a reminder that high-growth semiconductor names amplify market swings in both directions.
