When U.S. markets close on Wednesday, May 27, Marvell Technology, Inc.(MRVL.US) will release its Q1 fiscal 2027 earnings — and the stakes are unusually high. Shares have surged more than 130% year-to-date, pushing market cap above $170 billion and making the company one of the best performers in the Philadelphia Semiconductor Index (PHLX Semiconductor(SOX.US)/PHLX Sox Semiconductor Sector Ishares(SOXX.US)).

What Wall Street Wants to See

Consensus expectations heading into the print:

• Revenue of $2.4 billion, up 26% year-over-year
• Adjusted EPS of $0.77, up 21% year-over-year
• Data center revenue growth of roughly 10% quarter-over-quarter

For context, last quarter (Q4 FY2026) delivered a record ~$2.22 billion in revenue (+20% YoY) and $0.80 in adjusted EPS — both beating estimates. The data center segment alone contributed about $1.65 billion, or 74% of total revenue, and grew ~21% YoY. Management described order intake as growing at a "record pace."

But hitting the numbers won't be enough on its own. Goldman Sachs analysts flagged three items investors should watch on the earnings call: updates on a potential Google partnership, refreshed fiscal 2027–2028 guidance, and any near-term gross margin volatility. RBC Capital added that custom XPU demand looks strong, but tight wafer supply could cap short-term upside.

The Two-Engine Bull Case

Wall Street increasingly frames Marvell as a "dual-engine asset" benefiting from both custom AI chips and optical interconnects.

Engine 1 — AI ASICs (custom AI chips). Marvell's FY2026 data center business generated a record $6.1 billion. Its custom chip line now runs at roughly $1.5 billion annualized, with design wins across 18 cloud providers. The client list includes Amazon (Trainium), Microsoft (Maia), Meta (data processing units), and Alphabet (Axion ARM CPU).

Two recent developments matter most:

• Google talks. According to multiple reports, Alphabet Inc. Class A(GOOGL.US) is negotiating with Marvell to co-develop two new AI chips — a processing-in-memory (PIM) unit designed to work alongside Google's TPU, and a new TPU optimized for inference. Sources say both sides aim to finalize the PIM design and begin pilot production before 2027, with an initial run of nearly 2 million chips. (For scale: Google's annual TPU output is ~6 million.) Notably, Google isn't replacing Broadcom — it's diversifying its supply chain.
• Amazon–Anthropic deal. On April 20, Anthropic committed over $100 billion to AWS (Amazon.com, Inc.(AMZN.US)) technologies over the next decade, with Marvell-co-designed Trainium chips central to the agreement. Wells Fargo reports Anthropic has already deployed 1 million+ Trainium chips on AWS, with Trainium 3 ramping in H2 2026 to bring 2 gigawatts of capacity online. JPMorgan called Marvell "well-positioned to further expand its share in the upcoming Trainium 4."

Consensus now models FY2027 revenue at ~$11 billion (+30%), with the data center segment growing roughly 40% year-over-year.

Engine 2 — Optical interconnects. Beyond about 10 meters, copper can't keep up with AI cluster bandwidth requirements — which is where Marvell's optical DSPs and silicon photonics come in. Silicon photonics pushes optical connectivity deeper, from between racks down to inside racks, systems, and chip packages. Recent acquisitions of Celestial and Switzerland's Polariton Technologies underscore the push.

This engine also helped attract NVIDIA Corporation(NVDA.US), which invested $2 billion in Marvell at the end of March. According to a May 22 Oppenheimer report, the optical interconnect business has compounded at roughly 50% annually over five years, with growth expected to top 60% this year. Management has already raised FY2027 optical growth guidance from 30% to 50%.

Targets Keep Climbing

Heading into the print, major banks have lifted price targets sharply:

• Citi: Buy, $118 → $215 (+82%)
• Stifel: Buy, $140 → $210; expects a beat and a guidance raise
• BofA Securities: Buy, $125 → $200; named MRVL a "Top Pick"
• Wells Fargo: $135 → $195

The Other Side: Risks Investors Shouldn't Ignore

The optimism cuts both ways. Marvell trades at roughly 64x P/E, well above the industry average — meaning a lot of "perfect expectations" are already in the price.

• Valuation. If guidance signals any marginal deceleration in data center growth, the current premium will face renewed scrutiny.
• Execution and supply. The Celestial and Polariton integrations carry real challenges. Google talks haven't yet produced a formal contract. Advanced-node wafer, packaging, and substrate capacity remain tight industry-wide, though management says it has secured enough supply to support strong growth in the coming years.
• Customer concentration and competition. Amazon is Marvell's largest custom-chip customer under a five-year agreement — a meaningful single-customer exposure. Meanwhile, Broadcom is aggressively expanding its AI chip business, MediaTek has entered Google's TPU supply chain, and Advanced Micro Devices, Inc.(AMD.US) and Astera Labs(ALAB.US) add competitive pressure. ASICs as a category also still face competition from Nvidia's next-generation GPU platform; if GPU cost-performance keeps improving, some cloud customers may scale back ASIC deployments.
• Macro and geopolitics. U.S. semiconductor export restrictions, tariff policy, and broader trade dynamics weigh on a business heavily reliant on hyperscalers and global supply chains.

Bottom Line

Wednesday's print isn't just about whether Marvell beats — it's about whether the company can defend a valuation built on near-perfect expectations. The three things most likely to move the stock from here: forward guidance, any update on the Google partnership, and management's tone on supply constraints.
