Industry Analysis: AI Infrastructure Semiconductor — Structural Supercycle
Global hyperscaler CapEx in 2026 is expected to reach $660B~$690B, an increase of approximately 36% compared to 2025. FACT Of this, approximately 75% ($450B+) is directly invested in AI infrastructure. Goldman Sachs estimates cumulative hyperscaler CapEx for 2025-2027 at $1.15T, which is 2.4 times the previous three years ($477B).
The core beneficiary value chain of this investment spreads in the order of GPU/XPU → Custom ASIC → Optical Interconnect → Network Switching → Memory/Storage. Marvell is positioned in almost all areas of this chain except for GPUs, and in particular, has built a triangular formation of custom silicon, optical interconnect (PAM4/coherent DSP), and data center switching.
Industry Core Judgment: Bullish — High Confidence
Hyperscaler CapEx is structurally difficult to slow down in the short term due to the game-theoretic prisoner's dilemma of AI competition. An environment where "reducing investment means falling behind in competition." Deloitte forecasts total semiconductor industry revenue of $730B+ in 2026.
▶ Invalidation: If hyperscaler CapEx decreases QoQ for two consecutive quarters, the logic of the industry supercycle is invalidated.

Gross profit margin (Non-GAAP) of 59.5% is a temporary decline due to the increased proportion of custom silicon, and management expects a recovery to the 60% range after FY2027 due to scale effects and improved high-value optical product mix. FACT Operating profit margin expanded by 640bp (29.0%→35.3%), and the leverage effect has begun in earnest.
GAAP net income for FY2026 was $2.67B ($3.07/share), showing a dramatic improvement compared to the previous year. However, the gap between GAAP and Non-GAAP (adjustment items such as SBC) needs to be continuously monitored.

The Data Center Business Unit accounts for 74% of total revenue, surpassing $6B+ on an annual basis for FY2026 (+46% YoY). Three high-growth engines are operating within this:
Top 3 Growth Engines
1. Custom Silicon (AI ASIC): Achieved annual revenue of $1.5B, 2x+ compared to the previous year. 12 devices for 4 of the top 5 hyperscalers + 6 new AI customer projects in progress. FY2027 +20%+ growth expected. FACT
2. Optical Interconnect (Optics/DSP): Leading the 800G/1.6T PAM4 DSP market. Supplying DCI modules to all 5 major US hyperscalers. Acquired 16Tbps photonic fabric chiplets with the acquisition of Celestial AI. FACT
3. Data Center Switching: Switch revenue expected to exceed $600M+ in FY2027 (up from $500M previously). Continued demand for 12.8T products + ramp-up of 51.2T next-generation products. FACT
