Marvell Long-Term Outlook Lifted on Broad AI Momentum
Key Takeaways
Marvell’s fiscal 1Q27 results were in-line, but the FY27/FY28 revenue outlook was raised meaningfully on broadening AI strength. Data center revenue growth is now guided to ~50% in FY27, accelerating to ~55% in FY28 off a higher base. Interconnect is the core upside driver, with FY27 growth exceeding 70% as scale-up and scale-across vectors mature. Confidence in the custom XPU ramp for FY28 also increased materially, consistent with management’s “more than doubling” framework. We remain Equal-weight with a revised price target of $195. The long-term path is stronger, yet balanced by execution risk around multiple concurrent ramps.
Interconnect: The Underappreciated Breadth
The move from ~50% to more than 70% FY27 interconnect growth is not merely a forecast adjustment—it signals a structurally larger revenue pool. Management identified three vectors the market has not fully credited: TIAs/drivers reaching a $1B annualized run-rate in coming quarters, scale-up optics doubling from a prior ~$150M to over $300M next year, and scale-across emerging as a future driver. For investors, this means near-term revenue beats are likely even against a sharply raised bar, as FY28 interconnect is still expected to grow faster than 30%+ cloud capex. We model 80% FY27 and 45% FY28 interconnect growth, numbers that embed continued upside if AI infrastructure spend remains supply-constrained rather than demand-constrained.
Custom XPU: From Optionality to Visible Ramp
The FY28 custom XPU trajectory now rests on three concrete engines—the existing business, attach opportunities, and the tier-one ramp—rather than a single outlier program. Management’s increased confidence allows for modeling closer to their “more than double” target. We keep FY27 custom growth at ~25%, while lifting FY28 to align with management’s framework. The investment implication: the optionality narrative is converting into a visible, multi-year growth stream. However, since our forecast still excludes programs beyond the three named drivers, actual upside could exceed our estimates if additional customer engagements translate into volume.
Risk: Execution and Dilution
Marvell is funding simultaneous expansions across optics, switching, and custom silicon, with FY28 opex growth in the mid-to-high teens. While operating leverage remains strong, execution risk rises with complexity. Diluted share count increased from 856M to 893M in the quarter, with an additional 22M expected next quarter—meaning a portion of the revenue upside will be absorbed by share creep.
Valuation and Trade Implication
Our $195 price target reflects higher long-term estimates but an unchanged Equal-weight rating. The thesis is straightforward: interconnect momentum is durable and custom XPU is de-risking, which argues against underweight positioning. But concurrent ramps across multiple next-generation platforms introduce integration and supply-chain risk that compresses the reward-to-risk ratio at current levels. The long-term growth story has improved; the tactical entry point has not yet reset to an asymmetry that warrants an overweight.
