Marvell's Growth Story Hits a Wall of Margin Skepticism

Marvell beats Q2 estimates and raises outlook, but margin concerns and Google deal clarity trigger 9.5% stock drop.

There is a peculiar paradox taking hold in the semiconductor trade: deliver record numbers, raise the full-year outlook, and watch the stock get sold off anyway. Marvell Technology found itself on the wrong side of that dynamic on Friday, and the shares have been nursing the wounds ever since.

The Numbers That Should Have Landed Differently

The company reported record second-quarter revenue of $2.739 billion for fiscal 2027, up 37 percent year over year, with non-GAAP earnings per share of $0.94. Both figures cleared consensus estimates of $2.71 billion and $0.93, respectively. The data center segment — now the corporate centerpiece — grew 46 percent to $2.17 billion, representing 79 percent of total revenue.

Management also raised its full-year revenue guidance to roughly $12 billion, up from a prior $11.5 billion, and introduced a first-time fiscal 2028 target of approximately $18 billion. The third-quarter outlook called for $3.15 billion in revenue and EPS between $1.05 and $1.15, again ahead of expectations.

None of it was enough. The stock fell 9.5 percent on Friday to close at €187.50, leaving it down 4.7 percent on the week and roughly a third below its 52-week high of €290.35. The secondary article notes a steeper weekly decline of 7.6 percent, with the shares now trading beneath the 50-day moving average of €198.13 — a technical signal that near-term momentum has faded.

Margins Are the Problem Child

The culprit is gross margin. Investors bristled at a softer margin outlook, which management attributed to a rising mix of custom silicon — a business that grows faster than standard products but carries thinner margins. Adding to the disappointment, executives clarified that the Google AI deal announced in August was already fully baked into the long-term forecast. Anyone hoping for an incremental revenue boost from that partnership was left empty-handed.

This is the flip side of the AI rally: expectations have outrun the fundamentals. A company can do nearly everything right and still get punished because the market had already priced in more.

The Google Relationship Deepens — But on a Long Fuse

Beyond the headline numbers, the Google partnership is quietly expanding across multiple fronts. The collaboration, previously centered on custom tensor processing units, now extends to network interface cards, storage controllers, and memory controllers. Google has been selling its TPUs to external customers, and the broader product scope positions Marvell as a wider infrastructure partner for Google's data centers rather than a supplier of a single chip type.

The financial mechanics of the relationship remain anchored by the previously disclosed equity warrant: Google can acquire up to roughly 59 million Marvell shares at $206.58 each, representing a potential value of around $12.2 billion. Full exercise is tied to cumulative revenue targets of up to $120 billion through fiscal 2033. That extended timeline explains the market's muted reaction — the revenue effects of the expanded partnership will take years to materialize.

Competitive Pressures Mount

The Google expansion also reads as a response to intensifying competition in the custom-chip arena. Nvidia reported data center revenue of $89 billion for its latest quarter, up 117 percent, and is pushing beyond GPUs into CPUs, storage, and networking with its Vera Rubin architecture. Meanwhile, Broadcom is reportedly in talks over a debt financing package of up to $100 billion to fund its own custom AI chips and networking infrastructure for hyperscalers.

In that environment, a broader product footprint at Google gives Marvell additional anchor points in the hyperscaler business — even if the payoff is measured in years rather than quarters.

Strategic Moves Beyond the Balance Sheet

Alongside the earnings, Marvell announced two acquisitions to bolster its data center connectivity business: XConn and Celestial AI. Nvidia also deepened its ties by subscribing to $2 billion in Series A convertible preferred stock — a signal that the big AI players view Marvell as a strategic partner, not merely a vendor.

On capital management, the company repurchased $400 million of stock in the first half of the fiscal year, with $5.1 billion remaining under the current buyback authorization.

Analysts Split, but Seldom Bearish

Monday brought the first post-earnings analyst reactions. Morgan Stanley's Joseph Moore raised his price target from $224 to $246 while keeping an Equal-weight rating. His reasoning: data center revenue should grow 60 percent in 2027, up from a prior assumption of 50 percent. Even a cautiously rated analyst sees structurally more growth — the skepticism targets margins, not the narrative.

What Comes Next

The selloff underscores how sensitive the market has become to any hint of margin pressure, even when growth is intact. Marvell will lay out its long-term AI infrastructure strategy at an investor day on October 6. Until then, the stock is likely to oscillate between growth optimism and margin anxiety — a pattern that has become all too familiar for AI supply chain names.
