Trainium 3 and optical communications demand are expected to drive upward revisions to Marvell's next-quarter guidance and CY27—CY28 data center outlook

Overview

This report assesses Marvell's near-term performance, next-quarter guidance, and CY27—CY28 data center growth prospects ahead of its F2Q27 results. J.P. Morgan expects the quarter's results to meet or slightly exceed consensus and believes Trainium 3, optical DSPs, switching chips, Maia, and XPU companion chips will support subsequent revenue and earnings above market expectations, thereby reiterating its Overweight rating.

Core views

J.P. Morgan expects Marvell's F2Q27 (July quarter) results to meet or slightly exceed market consensus, with the data center business remaining the primary support. Demand for optical DSPs driven by 1.6T and 800G programs remains strong, Teralynx 10/51.2T switching chips continue to make progress, and the custom-chip business is beginning to benefit from deepening XPU companion-chip projects and the initial ramp of AWS's next-generation 3nm Trainium 3 XPU ASIC. Trainium 3 shipments are expected to increase more significantly in the second half of the year, although near-term incremental gains may be partially offset by the gradual production decline of Trainium 2. For F3Q27 (October quarter), the report expects the company's revenue guidance to exceed the current market expectation of US$3.028 billion and potentially approach US$3.1 billion, corresponding to total revenue growth of 13%—14% quarter over quarter. This view is primarily based on the accelerating ramp of Trainium 3, sustained demand for optical DSPs and switching chips, expanding XPU companion-chip opportunities, and continued progress on Microsoft's 3nm Maia program. The 3nm Maia program is still scheduled to begin ramping in late 2026 and has a strong CY27 order backlog; the report also believes design work has begun on the next-generation 2nm Maia program. Because these drivers are concentrated in the data center segment, the report expects F3Q27 data center revenue to grow faster than the company overall, potentially increasing approximately 16%—18% quarter over quarter. Beyond near-term results and guidance, the report believes the most important point to watch in this earnings release is how management characterizes the CY27 and CY28 data center outlook. Over the past 90 days, J.P. Morgan has become more confident in the breadth and durability of Marvell's AI data center growth drivers. Optical DSP demand, Teralynx 10 progress, storage and CXL controller ramps, Trainium 3 shipments, visibility into Trainium 4 and Maia programs, and the expanding pipeline of XPU companion chips collectively support CY26—CY28 revenue and EPS above market consensus. The report therefore believes CY27 data center growth has meaningful upside relative to the current market expectation of 55% year-over-year growth. Google's expanded partnership with Marvell further validates the company's position as a partner for cloud providers' merchant silicon and ASICs. The report emphasizes that this is not a core TPU order, but rather an incremental chip opportunity surrounding the accelerator, including SRAM-based AI inference offload engines, PCIe Gen5/Gen6 storage controllers, NICs, SmartNICs and DPU-class controllers, CXL-based memory interface controllers, and other high-value chips located around the accelerator. Because current market expectations do not yet fully incorporate this potential revenue, the report believes the partnership provides a clearer path to upside in CY28 revenue and earnings, with CY28 EPS potential approaching US$11.00 versus the current market expectation of approximately US$9.64. Overall, J.P. Morgan lists Marvell as one of its preferred names within its semiconductor coverage. Although the market continues to debate AI ASIC competition, optical communications market share, and the sustainability of cloud capital expenditures, the report believes the company's data center growth thesis has actually strengthened over the past 90 days: AI infrastructure investment is accelerating, multiple customer programs are ramping in stages, and the addressable market for custom chips is expanding from the accelerators themselves to a broader range of companion chips. The report therefore reiterates its Overweight rating; the most recently listed target price is US$240, versus a share price of US$237.04 on August 21, 2026.

Analysis framework

The report first assesses F2Q27 results based on demand and program ramp conditions across the optical DSP, switching-chip, and custom-chip product lines, and then maps the timelines of Trainium 3, Trainium 2, Maia, and XPU companion-chip programs to F3Q27 revenue guidance. It subsequently aggregates multiple customer and product drivers into the CY27—CY28 data center revenue and earnings outlook and compares them with market consensus to identify potential expectation gaps.

• Industry/Sector Analysis FrameworkVolume-price decomposition

  Explaining revenue growth through shipment ramps

  The report primarily explains revenue growth through increased Trainium 3 shipments, reduced Trainium 2 production, and demand changes across different product lines. Its growth assessment centers on changes in product and program volumes rather than pricing assumptions.

Impact & implications

The report believes Marvell's data center growth no longer depends solely on a single accelerator ASIC program, but is jointly driven by optical communications, switching chips, storage and CXL controllers, custom chips for multiple cloud customers, and a broader range of XPU companion chips. This expansion of growth drivers improves CY27—CY28 revenue and earnings visibility and may prompt upward revisions to management's data center outlook and market earnings expectations.

Risks

• Competition in the AI ASIC market may affect opportunities and growth in Marvell's custom-chip business.
• Uncertainty regarding optical communications market share may affect the sustainability of optical DSP growth.
• If cloud providers' capital expenditures are not sustained, data center demand may weaken.
• Reduced Trainium 2 production may partially offset growth from the initial Trainium 3 ramp.
