Marvell’s August 28 Decline Followed Lower Gross-Margin Guidance

Results and market reaction

Marvell Technology reported record fiscal second-quarter 2027 revenue of $2.739 billion on August 27, up 37% year over year and $39 million above the midpoint of its May guidance. GAAP net income was $308 million, non-GAAP earnings per share were $0.94, and operating cash flow was $605.5 million, according to the company’s quarterly results.

MRVL closed August 28 at $216.62, down $24.83, or 10.28%, from $241.45. The shares traded between $215.55 and $228.88, with reported volume of about 48.1 million shares. StockAnalysis placed Marvell’s market capitalization at $189.96 billion at that close, using 876.93 million shares outstanding; the one-day price movement equaled roughly $21.8 billion of equity value on that share-count basis. Historical trading data identify the price move but do not establish a single cause.

The clearest company-specific change was Marvell’s fiscal third-quarter non-GAAP gross-margin guidance of 57.5% to 58.5%. Its 58.0% midpoint was about 90 basis points below the 58.9% non-GAAP gross margin reported for the second quarter. Marvell’s GAAP gross-margin guidance of 52.9% to 53.9% did not indicate the same sequential midpoint decline.

Custom mix and profitability

Chief Financial Officer Dan Durn said product mix and the expected acceleration of the custom business were creating the sequential gross-margin headwind. He said fourth-quarter gross margin was expected to remain in approximately the same range. B. Riley Securities analyst Craig Ellis also described the third-quarter margin outlook as below his estimate because of greater custom-product mix, according to MT Newswires reporting.

The guidance indicates a lower gross-margin percentage alongside substantially higher expected gross-profit dollars, if Marvell reaches the midpoints. Third-quarter revenue guidance is $3.15 billion, plus or minus 5%, and the 58.0% non-GAAP gross-margin midpoint implies about $1.827 billion in gross profit. Second-quarter revenue and gross margin imply about $1.613 billion in non-GAAP gross profit. That arithmetic equates to an increase of roughly 13%.

Marvell’s data-center revenue reached $2.1715 billion in the second quarter, up 46% year over year and 18% sequentially. The segment supplied 79% of total revenue, compared with 74% a year earlier. This concentration increases the company’s exposure to hyperscaler spending, customer program schedules, product transitions, and the economics of custom silicon.

Management raised its fiscal 2027 revenue outlook to roughly $12 billion from about $11.5 billion and its fiscal 2028 outlook to approximately $18 billion from $16.5 billion. It also increased expected fiscal 2027 data-center growth to about 60% from about 50%, as reported in the earnings-call guidance update. The stock decline therefore occurred alongside higher company revenue targets.

Google revenue timing and remaining questions

Marvell and Google LLC entered a custom-semiconductor agreement on July 29 covering products linked to Google’s TPU ecosystem. On August 18, Marvell issued Google a warrant for up to 58,970,907 shares at an exercise price of $206.58 per share. Most shares vest through discretionary qualifying purchases, with one tranche vesting for each $500 million of revenue through fiscal 2033, according to the Google agreement filing.

The maximum warrant share count equals roughly 6.7% of Marvell’s August 28 shares outstanding. That figure does not represent immediate dilution because vesting, exercise, qualifying purchases, and future share counts remain uncertain. Claims that the agreement guarantees $120 billion of orders are unsupported: $120 billion is the arithmetic revenue amount needed to vest all 240 purchase-linked tranches, while Google’s purchases are discretionary.

Chief Executive Matt Murphy said revenue from Google programs through fiscal 2028 was already reflected to some extent in Marvell’s custom-revenue targets and should become more significant in fiscal 2029. Morgan Stanley said investor expectations had been higher because the Google announcement had been viewed as potentially more incremental, according to Reuters reporting. This supports an expectations-based component to the August 28 reaction.

The evidence supports a margin-and-expectations reset rather than a single-cause explanation for the 10.28% decline. It remains unclear where third-quarter revenue and margin will land within guidance, whether margins improve after the fourth quarter, and how much raised fiscal 2028 revenue reflects Google programs. Marvell’s next scheduled investor event is Investor Day on October 6, 2026, in New York City.
