Marvell (MRVL) Q3 2026 earnings review
AI Momentum Accelerates; Marvell Acquires Celestial AI to Target Scale-Up Interconnect Market
Marvell delivered another record quarter, with revenue of $2.075B and Non-GAAP EPS of $0.76 both beating guidance, driven by relentless AI demand in its Data Center segment. The company provided an exceptionally strong outlook, forecasting Q4 revenue to accelerate to $2.2B and guiding for FY27 Data Center revenue growth of over 25%. The highlight of the quarter was the transformational acquisition of Celestial AI, a strategic move to capture the multi-billion dollar scale-up interconnect market with photonic fabric technology. With the core Data Center business firing on all cylinders, cyclical communications markets recovering, and a bold new acquisition, Marvell is aggressively positioning itself as a foundational enabler of the entire AI infrastructure stack.
🐂 Bull Case
Management provided rare long-term visibility, guiding for over 25% Data Center growth in FY27 and accelerating growth in FY28. This signals immense confidence in its design win pipeline and market position.
The acquisition of Celestial AI and its photonic fabric technology positions Marvell to dominate the emerging, high-margin scale-up interconnect market, a critical component for future large-scale AI clusters.
Beyond AI, the core Communications & Other segment is showing a firm recovery, with implied organic growth of ~50% YoY. This provides a secondary growth driver and diversifies the revenue base.
🐻 Bear Case
The rapid ramp of high-volume, lower-margin custom silicon is pressuring corporate gross margins, with Q4 guidance implying a dip to 59.0%. While operating margin is expanding, this mix shift caps gross margin upside.
Celestial AI has aggressive revenue targets, aiming for a $1 billion run rate by the end of FY29 from a base of zero. Integrating the technology and achieving this rapid commercial scale-up carries significant execution risk.
Despite a growing design pipeline, a significant portion of the custom silicon revenue ramp remains tied to a few large US hyperscale customers, exposing the company to shifts in their specific buildout plans or design choices.
⚖️ Verdict: 🟢🟢
Very Bullish. The strong quarterly beat and accelerating forward guidance would be enough for a bullish rating, but the highly strategic acquisition of Celestial AI and the unprecedented multi-year growth forecast signal a step-function change in the company's trajectory. Marvell is successfully executing its transformation into a central pillar of the AI ecosystem, and the long-term visibility provided by management significantly de-risks the growth story.
Key Themes
New Multi-Year Outlook Signals Sustained High Growth
In a significant display of confidence, management provided a framework for robust long-term growth. The company now expects Data Center revenue to grow over 25% in FY27, followed by an acceleration to approximately 40% growth in FY28. This outlook is underpinned by strong customer demand, purchase orders covering the next-generation custom XPU ramp, and a burgeoning pipeline of XPU attach sockets. This level of forward visibility is rare and suggests a durable, multi-year growth cycle.
Celestial AI Acquisition Targets New Multi-Billion Dollar Interconnect Market
Marvell announced the acquisition of Celestial AI, a leader in photonic fabric technology. This move targets the massive emerging market for 'scale-up' interconnects, which optically connect hundreds of XPUs within AI clusters. Celestial AI's technology promises 2x the power efficiency of copper with longer reach and nanosecond latency. Crucially, the company has already secured a major design win with a large hyperscaler for a next-gen deployment, with revenue projected to hit a $500M run rate in Q4 FY28 and $1B by Q4 FY29.
Custom Silicon and XPU Attach Pipeline Expands
Momentum in custom silicon remains exceptionally strong. Management noted a product transition for its lead XPU customer is fully baked into forecasts, with purchase orders for the entirety of FY27. More importantly, the XPU attach market is accelerating. Marvell highlighted 5 CXL design wins and multiple custom NIC wins, projecting over $2 billion in revenue from these use cases alone by FY29. They also secured a new win for an electrical I/O chiplet, opening another avenue for growth.
Core Networking Markets Show Firm Recovery
The Communications and Other segment posted strong results, growing 34% YoY. Excluding the divested auto business, underlying growth was closer to 50% YoY, indicating the cyclical inventory correction in enterprise and carrier markets is firmly in the past. The company guided for this segment to grow 10% in FY27, providing a stable, secondary growth driver to complement the AI hyper-growth.
Gross Margin Pressured by Favorable Mix Shift
While driving enormous profit dollar growth, the rapid ramp of custom silicon continues to pressure the corporate non-GAAP gross margin percentage. The Q3 margin was 59.7%, and guidance for Q4 is a midpoint of 59.0%, down from 60.5% in the prior year quarter. This trend is structural and reflects the trade-off of winning massive, but lower-margin, custom deals.
Contradictory Data Point: Accounts Receivable Growth Outpaces Sales
While the narrative is one of flawless execution, Accounts Receivable jumped to $1.55B from $1.03B at the end of FY25. This 50% increase significantly outpaces the ~14% sequential revenue growth over the same period (Q4 FY25 to Q3 FY26), implying a Days Sales Outstanding (DSO) increase from 51 to ~67. While not mentioned on the call, this could indicate changing payment terms with large customers or a back-end loaded quarter and warrants monitoring.
Other KPIs
Accelerating. The operating margin expanded by 150 basis points sequentially, from 34.8% in Q2, and is up significantly from 29.7% in the year-ago quarter. This demonstrates powerful operating leverage, as high-margin R&D investments are paying off with revenue growth that is far outpacing expense growth. This leverage is the key counterpoint to the modest gross margin compression.
A new record. Cash generation remains robust, funding $1.3B in share repurchases and $51M in dividends during the quarter. The company's strong balance sheet and cash flow provide the strategic flexibility to fund acquisitions like Celestial AI while continuing capital returns.
Management expects switching revenue to surpass $300M this fiscal year and accelerate to over $500M next year (FY27). This is faster than previously indicated and is driven by sustained demand for 12.8T switches and the ramp of next-generation 51.2T products.
Guidance
Accelerating sequentially. The midpoint implies 6.1% sequential growth, an acceleration from Q3's 3.4%. The implied YoY growth of 21.1% represents a deceleration from Q3's 37%, largely due to increasingly difficult comparisons from the prior year's AI ramp.
Stable sequential growth. The midpoint of $0.79 represents 4% sequential growth and 32% YoY growth. This is slower than revenue growth, reflecting higher guided operating expenses in Q4 related to employee bonuses from a strong year.
Accelerating outlook. This new guidance implies total company revenue approaching $10 billion in FY27. The Data Center growth of >25% implies an acceleration from the ~21% implied YoY growth for the overall company in Q4 FY26, signaling strong momentum heading into next year.
