- What they said
- onsemi reported strong Q2 2026 results with revenue of $1.6 billion, non-GAAP gross margin of 39.3%, non-GAAP diluted EPS of $0.74, and $425 million of free cash flow. Management emphasized recovery-driven margin expansion and operating leverage, noting revenue and margin results were above the midpoint of guidance. AI data center was highlighted as the fastest-growing market with management saying AI data center revenue is expected to more than double in 2026; design wins include expanded role in the NVIDIA MGX ecosystem, two platform wins with Great Wall, and engagements with U.S. hyperscalers including AWS. Management prioritized shipments to AI data center over automotive and industrial in Q2 due to constrained supply in certain power lanes; lead times extended (from ~27 to ~32 weeks) and orders within lead time and customer escalations increased. Management reported completed non-core revenue exits (~$35M in Q2, ~ $300M annualized for the year) and continued cost/portfolio actions; depreciation is steady and planned CapEx is primarily maintenance and below prior targets for the year. Management is confident in continued gross margin expansion driven by utilization increases (25–30 bps gross margin improvement per 1 point utilization uplift) and expects subsegment Q3 trends of auto up low-single digits, industrial flat, and other (AI data center) up high teens percent sequentially. The company increased long-term TAM estimates materially for AI data center and EV/electrification driven by higher content per rack and silicon carbide and Treo/other product adoption.
- Guidance
- Q3 subsegment directional guidance: automotive up low single digits sequentially; industrial relatively flat; "other" (which includes AI data center) up high teens sequentially. Management also guided to continued gross margin expansion through the remainder of the year as utilization increases (stating 25–30 bps gross margin improvement per 1 point of utilization). Management expects AI data center revenue to more than double in 2026 (forward-looking thematic guidance).
- Risks flagged
- Supply tightness in specific power product lanes and extended lead times (from ~27 to ~32 weeks) could limit near-term fulfillment and forced prioritization across end markets. Input material cost increases (substrates, gold, etc.) are persistent and management stated they are not seeing cost declines, requiring pricing actions to offset; this creates margin risk if pricing cannot fully offset increases. Prioritization of AI data center shipments led to short-term reductions in automotive/industrial shipments; if manufacturing catch-up is slower than anticipated, it could pressure those end markets. Some capacity is not fungible and there are short-term allocation challenges despite external partner flexibility.
