Marvell Technology, Inc. (NASDAQ:MRVL) experienced a sharp decline on Thursday, closing at $245.29, a drop of 9.84% from the previous session. The sell-off occurred just before the Nasdaq and NYSE closed for the Independence Day holiday on Friday, July 3, 2026. The stock's plunge erased approximately $23.4 billion in market capitalization in a single day, a figure that is roughly 3.2 times the company's annualized first-quarter data-center revenue run rate of $7.33 billion.
The decline was notably steeper than those of its AI-chip peers. Nvidia Corporation (NASDAQ:NVDA) fell 1.47%, Broadcom Inc. (NASDAQ:AVGO) dropped 2.48%, Advanced Micro Devices, Inc. (NASDAQ:AMD) slid 4.24%, and Micron Technology, Inc. (NASDAQ:MU) lost 5.45% in the same session. The broader market also saw weakness, with the Nasdaq Composite (INDEXNASDAQ:IXIC) declining 0.8%, while the S&P 500 (INDEXSP:.INX) was nearly flat, and the Dow Jones Industrial Average (INDEXDJX:.DJI) set a new record, according to the Associated Press.
Marvell's weekly performance was particularly severe. After trading higher early Tuesday, shares reversed sharply, ending the week 17.7% below Tuesday's close and 8.1% lower than the previous Friday's closing price of $266.77. The holiday-shortened week saw heavy losses despite lower-than-average volume in some sessions, highlighting the intensity of the sell-off.
The company's current valuation reflects its heavy reliance on data-center revenue, which accounted for 76% of total sales in the most recent quarter. In its latest 10-Q filing, Marvell warned that a significant reduction in AI capital expenditure by customers could materially impact its financial results. This vulnerability is underscored by the fact that the stock now trades at approximately 29.3 times its annualized first-quarter data-center revenue, down from 32.5 times before the sell-off.
Marvell reported record first-quarter fiscal 2027 revenue of $2.418 billion, a 28% year-over-year increase. The company guided second-quarter revenue to $2.7 billion, plus or minus 5%. CEO Matt Murphy highlighted "exceptional AI-related bookings" and said the company is "significantly raising" its revenue outlook for fiscal 2027 and 2028. However, margin expansion remains a key focus, with non-GAAP gross margin guidance for the second quarter set at 58.25% to 59.25%. Zacks noted that margin improvement is not the primary earnings driver for Marvell currently, pointing instead to its expansion into custom silicon, optical components, and switches.
An insider transaction added to market unease. Marvell President and COO Chris Koopmans sold 10,000 shares on July 1 through a 10b5-1 plan established on January 5. The sale, valued at approximately $2.82 million at a weighted average price of $281.92, represents just 0.0011% of Marvell's 874.8 million shares outstanding. While the transaction is small relative to the company's size, it may have contributed to negative sentiment during a volatile period.
The broader AI sector faced headwinds ahead of the holiday, with Asian stocks finding some footing after two sessions of tech losses, according to SPI Asset Management's Stephen Innes. Marvell's next significant corporate event is the dividend record date on July 10 for a quarterly payout of $0.06 per share, scheduled for July 30. The company has no other major events on the calendar for the near term.
