Marvell Technology Stock Slides 10% on Google…

MRVL shares dropped 10% after a Q2 FY2027 revenue beat, as murky Google AI chip deal details and below-par fiscal 2028 margins stoke investor concern.

Marvell posted record Q2 FY2027 revenue of $2.74B, up 37% year over year, with adjusted EPS of $0.94, beating consensus.
MRVL shares fell 10.28% to $216.62 as investors flagged an opaque Google TPU deal timeline and compressed fiscal 2028 margin guidance.
Gross margin guidance of 57.5%-58.5% disappointed a Street that had priced in a steeper expansion trajectory.

Lead

Marvell Technology (MRVL) delivered record fiscal second-quarter results on August 27, 2026, posting revenue of $2.739 billion - up 37% year over year - alongside adjusted earnings per share of $0.94, clearing Street estimates on both measures. Shares nonetheless fell 10.28% the following session, closing at $216.62 against a prior close of $241.45, and the selloff persisted through the Labor Day long weekend. Investors focused not on what management said but on what it withheld: a clear revenue ramp timeline for the company's high-profile Google (GOOG) custom AI silicon program, and a fiscal 2028 gross margin outlook that trailed the elevated bar the market had set.

Why Did Marvell Shares Fall on a Record Quarter?

The earnings-day drop traced to two distinct pressure points. First, Marvell guided non-GAAP gross margin for the coming quarters to a range of 57.5% to 58.5%, retreating from the 58.9% posted in Q2 and stepping further back from the 59.4% reported a year earlier. Management attributed the compression to the mix headwind created by high-volume custom AI silicon production, which carries structurally lower margins than standard semiconductor products. For a stock that entered the earnings session up more than 60% year-to-date and was priced for flawless execution, an incremental margin retreat was sufficient to trigger widespread profit-taking.

Second, the company raised its fiscal 2028 revenue outlook to approximately $18 billion - up from $16.5 billion just one quarter prior - yet declined to provide specific contribution breakdowns tied to the Google partnership, leaving investors without a concrete ramp schedule to anchor valuation models.

What Is the Google AI Chip Deal, and Why Does the Timeline Matter?

Under a commercial agreement signed July 29, 2026, Marvell is co-developing a suite of custom silicon for Google's TPU ecosystem, encompassing AI inference accelerators, storage controllers, network interface controllers, memory interface controllers, and near-memory compute. Google received warrants to acquire up to 58.97 million Marvell shares at $206.58 each - a potential $12.2 billion warrant exercise tied to cumulative qualifying revenue milestones running from August 1, 2026, through January 29, 2033.

The structure makes the deal's full value contingent on Marvell generating as much as $120 billion in qualifying revenue over that window. Crucially, management signaled that the program's largest revenue contribution lands in fiscal 2029 and beyond, not in the fiscal 2027 or 2028 windows that investors had been modeling. That multi-year gap between deal announcement and meaningful revenue is precisely what the market refused to set aside going into the long weekend.

How to Invest in AI Chip Stocks Around Earnings

Marvell's post-earnings slide illustrates a pattern that has recurred across the AI semiconductor trade: even a beat-and-raise quarter can punish shareholders when valuation already prices in best-case scenarios. Eight Wall Street firms raised price targets the morning after the drop, with the average consensus settling near $257 - implying roughly 18% upside from current levels - yet near-term enthusiasm remains capped by the margin and timing questions left unresolved on the call.

Data Center revenue, now the dominant segment, is projected to grow approximately 60% in fiscal 2027 and above 60% in fiscal 2028, driven by broad strength in interconnect, switching, and custom silicon. Non-GAAP operating margin is targeted to enter the 38% to 40% range by Q4 of fiscal 2027, with progression toward the upper end expected through fiscal 2028. The CFO pointed to the accelerating custom chip business as the structural source of near-term gross margin pressure, framing it as a deliberate trade-off to capture long-term hyperscaler share.

Outlook

Marvell enters the post-Labor Day trading week having delivered record revenue while leaving two material uncertainties unresolved - the gross margin recovery path through the custom silicon ramp, and the Google program's contribution window. The fiscal 2028 revenue target of $18 billion signals genuine confidence in AI infrastructure demand. Until management provides milestone-level granularity on the Google partnership's revenue cadence, however, the stock's premium to semiconductor sector peers faces ongoing de-rating risk on any macro or sector volatility, with the $216 level serving as the market's near-term verdict on what the ambiguity is worth.
