Marvell Technology Looks Undervalued as Artificial Intelligence Spending Surges

Marvell Technology has become a deeply discounted AI-chip play—its stock is down about 25% year-to-date despite accelerating revenue growth—after market rumors that it lost business from Amazon and Microsoft were publicly rebuked by CEO Matt Murphy. The company reported fiscal Q3 revenue up 37% year-over-year (following +63% and +58% in Q1 and Q2), operating income up 23%, and a forward P/E of roughly 23.5; Q3 net income was boosted by a one-time $2.5 billion sale of its automotive Ethernet business. Strategically, Marvell sold the slower business to free capital and bought photonics specialist Celestial AI for $3.25 billion (potentially $5.5 billion with earnouts) to scale custom AI chips for data centers—an acquisition praised by an AWS executive—and if Marvell sustains ~30%+ growth the valuation gap could prompt a material rerating, although market skepticism currently caps the stock.

Analysis

Marvell Technology (MRVL) is trading roughly 25% below its level at the start of the year after market rumors that it lost business from Amazon and Microsoft weighed on the stock; CEO Matt Murphy publicly rebuked those claims on CNBC, but the rumor's credibility continues to depress sentiment. The selloff appears disconnected from company commentary and third-party validation cited later in the article.

Financial results show accelerating top-line momentum: fiscal Q3 (ended Nov. 1) revenue rose 37% year-over-year following prior-quarter gains of 63% and 58%, while operating income increased 23% year-over-year. Reported Q3 net income was materially lifted by a one-off $2.5 billion sale of its automotive Ethernet business; management has historically delivered roughly 10% net margins excluding that event and the stock trades at a forward P/E near 23.5.

Strategically, Marvell divested a slower business to free capital and acquired photonics provider Celestial AI for $3.25 billion (up to $5.5 billion with earnouts) to accelerate custom AI-chip adoption in data centers, a deal that drew public praise from an AWS compute executive. If Marvell sustains ~30%+ revenue growth into fiscal 2027, the valuation gap versus fundamentals could prompt a rerating, but hyperscaler concentration, integration/earnout execution, and lingering reputational effects from the rumor remain material risks.

Key Decisions for Investors

• Consider initiating a modest, conviction-weighted buy on weakness given sustained high single- to double-digit revenue growth and a forward P/E of ~23.5, but limit sizing until post-acquisition execution is clearer
• Monitor the next two fiscal quarters for organic revenue growth and margin expansion excluding the one-time $2.5B automotive sale as the primary catalysts before adding to core exposure
• Use hedges or option structures to protect against downside from customer-concentration risk or integration/earnout execution on the Celestial AI deal while reassessing position if credible evidence of lost hyperscaler business reappears
