Marvell Stock Analysis: Record Q3 Revenue and Celestial AI Acquisition

Marvell Technology, Inc. (NASDAQ: MRVL), a critical player in the data infrastructure semiconductor space, announced a strong third quarter for its fiscal year 2026, delivering record revenue and outlining a clear strategy to dominate the next phase of AI data center growth through a major acquisition.

Financial Performance: Record Revenue and Margin Strength

Marvell reported net revenue of $2.075 billion for Q3 FY26, a new record and $15 million above the mid-point of its guidance. This represents a robust 37% year-over-year growth.

While the GAAP figures were significantly boosted by the $1.8 billion pre-tax gain from the sale of the automotive ethernet business to Infineon, the core operational strength was evident in the non-GAAP metrics.

Non-GAAP profitability remained robust, with non-GAAP gross margin at 59.7% and non-GAAP diluted EPS of $0.76. Operating cash flow reached a record $582 million, enabling the company to return $1.35 billion to shareholders through buybacks and dividends during the quarter.

The Q4 FY26 guidance remains optimistic, forecasting net revenue of $2.2 billion (+/- 5%), non-GAAP gross margin of 58.5%–59.5%, and non-GAAP diluted EPS of $0.79 (+/- $0.05 per share).

Strategic Focus: Dominating the Data Center and AI Scale-Up

The core of Marvell’s valuation thesis lies in its Data Center segment, which remains the primary growth driver. The Data Center end market generated $1.518 billion in revenue, accounting for a massive 73% of consolidated revenue, and increasing 38% year-on-year. CEO Matt Murphy emphasized this momentum, forecasting full-year revenue growth to exceed 40% and, more importantly, raising the FY27 data center revenue growth forecast above prior expectations due to accelerating demand.

Key highlights underscoring this growth include:

• Double-digit sequential growth in optics, switching, and storage

• Over 20 custom XPU and XPU-attach sockets secured

• Five unique CXL sockets across two Tier-1 U.S. hyperscalers

• Expanding design momentum in AEC, PCIe retimers, and scale-up switching

Celestial AI Acquisition: Owning the Optical Interconnect Future

The most significant strategic move during the quarter was the definitive agreement to acquire Celestial AI for approximately $3.25 billion in upfront consideration (cash and stock), plus a potential $2.25 billion in performance-based earnouts.

The acquisition targets the critical need for optical scale-up interconnects within next-generation, multi-rack AI clusters. Celestial AI’s Photonic Fabric™ technology is designed to enable all-optical connections for XPU-to-XPU and switch connectivity, offering more than two times the power efficiency of copper interconnects. This secures Marvell’s position in the nascent, high-growth optical I/O market.

Marvell projects a rapid revenue ramp from Celestial AI, expecting meaningful contributions to begin in the second half of fiscal 2028, reaching a $500 million annualized run rate in the fourth quarter of fiscal 2028, and doubling to a $1 billion run rate by the fourth quarter of fiscal 2029.

Technical Outlook

From a technical perspective, the $110 level is identified as the key resistance for MRVL stock. A sustained breakthrough above $110 on strong volume would confirm continued bullish momentum and likely open the path toward $125.

On the other hand, if the stock fails to breach the $110 resistance, it risks a corrective move. The initial line of support to watch is $81. Should this level fail to hold, a further pullback could see the stock seeking stronger support in the $71 to $62 range.
