Marvell Technology (NASDAQ: MRVL) delivered a good quarter and an even better guide. The $211.5B semiconductor firm posted record Q2 FY2027 revenue of $2.739 billion, a 37% year-over-year jump that beat its own guidance midpoint by $20 million. Non-GAAP EPS of $0.94 topped consensus by a penny. Those headlines understate the real story. This is a company whose Data Center business is accelerating, with a Q3 guide that implies a revenue step-change few models predicted.
Revenue of $2.739 billion landed $20 million above the prior guidance midpoint. Non-GAAP gross margin held steady at 58.9%, flat sequentially and down only 50 basis points from the year-ago 59.4%. Remarkable stability for a company growing revenue at 37%. Operating cash flow jumped to $605.5 million from $461.6 million a year earlier, providing ample funding for the quarter's $200 million in share repurchases.
The engine is Data Center. The segment drove $2.172 billion in revenue, up 46% year-over-year and 18% sequentially. It now accounts for 79% of total revenue, up from 74% a year ago. Communications and Other revenue, at $568 million, rose 10% YoY but fell 3% sequentially. A reminder that non-AI end markets remain mixed. The Data Center acceleration is broad-based, spanning Connectivity and a Custom business ramp management said began in the second half of fiscal 2027.
The Q3 guidance is the statement. Marvell sees revenue at a $3.15 billion midpoint, plus or minus 5%, implying 15% sequential growth from Q2's $2.74 billion. Non-GAAP gross margin is guided to 57.5%-58.5%, a 40-140bp dip from Q2's 58.9%. This points to a mix shift toward lower-margin Custom ASIC revenue starting to register. Non-GAAP EPS guidance of $1.05-$1.15 (midpoint $1.10) means 17% sequential growth from Q2's $0.94. The revenue guide alone was $150 million ahead of the $3.0 billion consensus midpoint.
Management also lifted its full-year fiscal 2027 and 2028 revenue outlooks from last quarter. A notable acceleration in confidence. The company cited "broad-based strength across our Data Center portfolio" and a "significant acceleration in our Custom business beginning in the second half of fiscal 2027." The Custom ASIC ramp is the key variable. It brings higher revenue per R&D dollar but lower gross margins, explaining the guided margin compression even as revenue surges.
The buyback pace holds at $200 million per quarter. A reasonable cadence given Marvell's capital needs. Capex in Q2 was $126.7 million, up from $47.5 million a year ago. The balance sheet shows $3.93 billion in cash against $4.96 billion in long-term debt. The $2 billion preferred stock issuance in Q1 added flexibility, but the net debt position is manageable.
Next up: the October 6 Investor Day, where management will detail its long-term AI infrastructure strategy. The Q3 guide confirms the Custom ASIC ramp is real and material. The question is whether the gross margin compression is a temporary mix effect or a structural shift to lower-margin, higher-volume business. The 58.9% non-GAAP gross margin in Q2, flat sequentially despite a 13% revenue increase, shows Marvell is managing the mix well. The Q3 guide, with margins declining 40-140bp, will test that discipline. For now, Marvell is executing on the AI infrastructure thesis as well as any semiconductor company.
