Why Is Marvell (MRVL) Stock Surging Premarket Today? Bullish AI Revenue Forecast

Marvell Technology (MRVL) is making headlines this Friday morning after a blowout Q4 earnings report sent shares surging sharply in after-hours trading on Thursday, March 5, 2026. The semiconductor company not only topped Wall Street’s estimates for the quarter but issued forward guidance that dramatically exceeded analyst expectations, fueled by an accelerating boom in AI-driven data center infrastructure.

With Big Tech giants pouring hundreds of billions into AI buildouts, Marvell finds itself squarely in the crosshairs of one of the most powerful secular growth trends in the technology sector. Investors are now asking whether this earnings-driven rally marks a turning point for a stock that had underperformed the broader semiconductor group over the prior two quarters.

Q4 Earnings Beat and Record-Breaking Fiscal 2026 Results

Marvell delivered a strong Q4 for fiscal year 2026, reporting revenue of $2.22 billion, a 22% jump year-over-year, edging past analyst estimates of $2.21 billion. Adjusted earnings per share came in at $0.80, a penny ahead of the consensus estimate of $0.79, continuing a pattern of beats that has defined much of the company’s recent fiscal year.

CEO Matt Murphy highlighted that Marvell posted record full-year fiscal 2026 revenue of $8.195 billion, representing 42% growth year-over-year, driven by what he called “robust AI demand.” Non-GAAP EPS for the full year reached $2.84, an 81% increase year-over-year, underscoring the operating leverage embedded in the business model.

Murphy also noted that design wins in fiscal 2026 hit an all-time record, a forward-looking signal that growth momentum is far from peaking. Looking into Q1 FY2027, Marvell guided for revenue of approximately $2.40 billion, plus or minus 5%, well above the analyst consensus of $2.27 to $2.28 billion, and adjusted EPS of $0.79 versus estimates of $0.74.

Fiscal 2027 and 2028 Outlook: AI Infrastructure Spending as a Tailwind

The most striking element of Thursday’s report was Marvell’s long-range revenue outlook, which sent shares surging roughly 15% in extended trading. The company now expects fiscal 2028 revenue to grow nearly 40% and approach $15 billion, a figure that towers over the analyst consensus estimate of $12.92 billion compiled by LSEG.

Marvell also raised its fiscal 2027 revenue forecast to more than 30% growth year-over-year, nearing $11 billion, up from prior expectations of approximately $10 billion. President and COO Chris Koopmans attributed the confidence to visibility into hyperscaler capital spending plans and a record pace of bookings, stating the company feels “very confident” in hitting those numbers.

The optimism is well-grounded: Big Tech firms including Alphabet, Microsoft, Amazon, and Meta are expected to collectively spend at least $630 billion on AI infrastructure in 2026 alone, lifting demand for the custom ASICs and high-speed interconnect products that are core to Marvell’s data center franchise. Marvell also completed its $3.25 billion acquisition of Celestial AI — a photonic fabrics company — which is expected to further differentiate its chip-to-chip connectivity offering as AI clusters continue to scale.

As of pre-market trading on March 6, 2026 at approximately 5:03 AM EST, MRVL shares were trading at $84.49, up $8.81 or +11.64%, after closing the prior session at $75.68 — itself down 3.09% on the day before the earnings release. The stock’s 52-week range spans $47.09 to $102.77, and the current analyst average price target stands at $114.06, with the high target reaching $150.00, suggesting significant upside from current levels even after the premarket pop.

On a trailing basis, MRVL carries a P/E ratio of 26.65 and a forward P/E of 23.26, with a market cap of approximately $66.1 billion intraday. From a performance perspective, the stock has lagged year-to-date at -10.88% versus the S&P 500’s -0.22%, and is down 15.76% over the past year against the index’s +16.91% gain, but has outperformed over three and five years, up 73.75% and 86.01% respectively.

Analyst sentiment remains broadly constructive; Evercore ISI Group maintained its Outperform rating as recently as March 4, though it trimmed its price target from $156 to $133. Thursday’s results and upgraded outlook may prompt a fresh wave of price target revisions across the Street.
