Marvell Rides AI Data Center Wave in Earnings Call

Marvell Technology Group ((MRVL)) has held its Q4 earnings call. Read on for the main highlights of the call.

Marvell Technology Group’s latest earnings call struck an upbeat tone, underscored by record revenue, robust margin expansion, and sharp EPS growth. Management leaned into a bullish multi‑year outlook driven by surging AI data center demand and interconnect leadership, while acknowledging risks from higher inventories, rising operating costs, and heavy reliance on hyperscaler cloud spending.

Record Revenue Across Quarter and Fiscal Year

Marvell posted Q4 FY2026 revenue of $2.219 billion, up 7% sequentially and 22% year over year as AI‑driven demand continued to build. For the full year, revenue climbed 42% to $8.195 billion, or roughly 45% excluding the divested automotive Ethernet unit, marking the strongest top‑line performance in the company’s history.

Data Center Engine Powers Growth

The data center segment surpassed $6 billion in FY2026 revenue, growing 46% year over year and cementing itself as Marvell’s primary growth driver. In Q4 alone, data center revenue reached $1.65 billion, up 9% sequentially and 21% year over year, and management expects this engine to grow about 40% in FY2027 and close to 50% in FY2028.

Upgraded Outlook Signals Confidence

Management raised its FY2027 revenue outlook to approach $11 billion, more than 30% growth versus FY2026 and above its prior roughly $10 billion target. For FY2028, the company now projects revenue near $15 billion, implying close to 40% growth, with Q1 FY2027 guidance of $2.4 billion plus or minus 5% signaling about 8% sequential expansion at the midpoint.

Margin Expansion Underpins Profitability

Non‑GAAP profitability surged as FY2026 gross margin reached 59.5% and operating margin hit 35.3%, up 640 basis points from the prior year. In Q4, Marvell delivered a 59% non‑GAAP gross margin and 35.7% operating margin, showcasing improved scale and product mix even as it invests heavily in future growth.

EPS Delivers Outsized Growth

Earnings power followed the top‑line and margin gains, with FY2026 non‑GAAP diluted EPS jumping 81% to $2.84. Q4 non‑GAAP EPS of $0.80 came in slightly above guidance midpoint, reinforcing management’s narrative that the business is converting AI‑driven demand into tangible earnings growth.

Custom Silicon Business Ramps Rapidly

Marvell’s custom business scaled from virtually zero to $1.5 billion in FY2026 and doubled year over year as hyperscalers turned to tailored accelerators and network solutions. Management sees custom revenue growing more than 20% in FY2027 and at least doubling in FY2028, with visibility to more than $2 billion annually by FY2029 in NIC and CXL‑related designs.

Technology Lead in High‑Speed Interconnect

The company emphasized its leadership in interconnect, noting 1.6T products already in production and live demonstrations of 400‑gig‑per‑lane performance. Marvell also rolled out 2‑nanometer coherent DSPs for secure 1.6T ZR/ZR+ data center interconnect modules and 2‑nm 800G DSPs, while its switching roadmap includes ramping 51.2T platforms and sampling 100T devices.

Strategic Deals Target AI Scale‑Up

Recent acquisitions of Celestial AI and XConn are designed to deepen Marvell’s positioning in AI scale‑up infrastructure, including co‑packaged optics and PCIe/CXL switching. The company projects Celestial’s CPO solutions reaching a $500 million annualized run rate by Q4 FY2028 and $1 billion by Q4 FY2029, with both deals together expected to add about $250 million of revenue in FY2028.

Capital Returns and Strengthening Balance Sheet

Marvell continued to return substantial cash to investors, sending $2.245 billion back in FY2026 through buybacks and dividends, including $200 million of repurchases and $51 million of dividends in Q4. Total debt stands at $4.47 billion, but improving EBITDA drove gross leverage to 1.38x and net leverage to 0.57x, giving the company room to balance growth investments with shareholder returns.

Bookings Momentum and Secured Supply

Management highlighted accelerating bookings across the data center portfolio, supporting its aggressive growth plans and underpinning visibility into future quarters. The operations team reported that supply is aligned with multi‑year growth needs across advanced wafer nodes and packaging, aiming to avoid bottlenecks as AI‑related ramps intensify.

Inventory Build Raises Near‑Term Risk

Inventory climbed to $1.39 billion in Q4, rising $374 million sequentially as Marvell built working capital ahead of expected demand. While this positioning supports rapid growth, it could pressure near‑term cash conversion and margins if hyperscaler orders or AI spending were to soften unexpectedly.

Operating Expenses Step Higher With M&A

The company signaled a notable increase in non‑GAAP operating expenses, guiding Q1 FY2027 OpEx to about $575 million and GAAP OpEx to roughly $872 million. Celestial AI and XConn are expected to add around $75 million to FY2027 non‑GAAP OpEx, reflecting the cost of integrating new technologies and engineering teams before revenue contributions scale.

Delayed Revenue Impact From New Acquisitions

While strategically important, Celestial AI and XConn are not expected to materially contribute to revenue until FY2028, limiting their short‑term impact on the income statement. Investors will need patience as Marvell invests now for an AI optical and CXL opportunity that management believes will ramp meaningfully only in the back half of the decade.

Customer Concentration Heightens Exposure

A significant portion of Marvell’s growth is tied to a handful of top hyperscalers, with management acknowledging that the leading U.S. cloud players drive the bulk of capex behind its ramps. This concentration means that changes in spending plans or design wins at a few large customers could have outsized effects on revenue trajectories.

Competitive Landscape in Custom and XPU

Executives noted that the custom and XPU ecosystem remains noisy and competitive, with shifting processor roadmaps and aggressive rivals. Sustaining multi‑generation custom engagements will be critical, and any execution missteps or lost sockets could weigh on Marvell’s ambitious growth plans in accelerators and related silicon.

Reliance on Elevated Cloud CapEx

The sharply raised FY2027–FY2028 outlook leans heavily on the assumption that cloud capex and data center interconnect demand stay elevated as AI build‑outs continue. Management cautioned that a downturn in macro conditions or a reset in hyperscaler spending could materially affect the high‑growth scenario embedded in current guidance.

Debt, Cash Flow, and Liquidity Balance

Despite improving leverage metrics, Marvell still carries $4.47 billion of debt and generated $374 million of cash from operations in Q4, leaving it dependent on continued earnings momentum. With heavy capital returns, higher operating expenses, and a sizable working capital build, any shortfall in growth or margins could tighten liquidity and force a rethink of capital allocation.

Guidance Points to Continued AI‑Driven Growth

Looking ahead, Marvell guided Q1 FY2027 revenue to $2.4 billion plus or minus 5%, with non‑GAAP EPS between $0.74 and $0.84 and gross margins near current levels. For FY2027 and FY2028, management expects revenue to approach $11 billion and roughly $15 billion, respectively, driven by data center growth near 40% then 50%, accelerating custom silicon, and a path to non‑GAAP EPS well above $5 by FY2028.

Marvell’s earnings call painted the picture of a company riding the AI data center wave with record results, expanding margins, and an aggressive growth roadmap. While investor enthusiasm is likely to track the upbeat guidance and technology leadership, the story will hinge on hyperscaler capex staying strong and management executing through rising costs, inventory, and competitive pressure.
