  • Non-GAAP gross margin expanded to 38.5% for the third consecutive quarter, driven by manufacturing efficiency gains.

A Clear Inflection Point

ON Semiconductor (NASDAQ:ON) delivered first-quarter 2026 results that exceeded expectations across the board, signalling what management described as a definitive move beyond the cyclical trough. Revenue reached USD 1.51 billion, up 5% year-over-year, while adjusted earnings per share of USD 0.64 surpassed the consensus estimate of USD 0.60. The company returned USD 346 million to shareholders through share repurchases, equivalent to approximately 160% of free cash flow for the quarter.

"We exceeded expectations as demand strengthened through the quarter and we have moved beyond the cyclical trough on a path to recovery." - Hassane El-Khoury, President and CEO

Gross margin expanded to 38.5%, aided by higher manufacturing utilisation, which rose sequentially to 77%. Operating cash flow stood at USD 239 million, with free cash flow at USD 217 million. GAAP diluted loss per share was USD 0.08, weighed by USD 329 million in restructuring charges.

Q1 revenue of USD 1.51 billion beat the USD 1.49 billion estimate, adjusted EPS of USD 0.64 exceeded the USD 0.60 consensus, non-GAAP gross margin expanded to 38.5% for the third consecutive quarter, and free cash flow came in at USD 217 million against operating cash flow of USD 239 million and capital expenditure of just USD 22 million.

AI Data Centers: The Structural Growth Engine

The most consequential development in the quarter was the acceleration of AI data centre revenue, which grew more than 30% sequentially — nearly double the growth rate management had anticipated entering the period. This was driven by broader adoption across the full power delivery chain, spanning multiple XPU vendors and all leading hyperscalers. Management now expects AI data centre revenue to double on a full-year basis relative to 2025.

Onsemi positions itself as the only broad-based American power semiconductor supplier capable of addressing the complete data centre power tree, from high-voltage grid conversion to point-of-load delivery at the processor. Its partnership with Flex Power alone spans more than 30 active programmes, covering intermediate bus converters, power supplies, battery backup systems, and next-generation 800-volt DC architectures.

Automotive Recovery and Silicon Carbide Momentum

Automotive revenue of USD 797 million was roughly flat sequentially but rose nearly 5% year-over-year, marking the first annual growth in seven quarters. Management stated that inventory digestion is largely complete and that the company is now shipping to natural end demand. China remained the most dynamic automotive market, with Onsemi's silicon carbide accounting for approximately 55% of new EV models shown at the 2026 Beijing Auto Show. China automotive revenue grew year-over-year despite a 6% decline in the broader Chinese passenger vehicle market, highlighting the content-driven nature of the company's exposure.

The transition to 900-volt EV architectures — led by Chinese OEMs — is emerging as a significant opportunity, with Onsemi already in production at customers deploying next-generation platforms from Geely and NIO. Higher energy costs globally are reinforcing EV adoption economics, providing a durable demand backdrop for silicon carbide solutions.

Forward Guidance and Margin Expansion Path

For the second quarter of 2026, Onsemi guided revenue of USD 1.535 billion to USD 1.635 billion, above the analyst consensus of USD 1.53 billion. Non-GAAP adjusted EPS is expected in the range of USD 0.65 to USD 0.77, against an estimate of USD 0.65. Non-GAAP gross margin guidance of 38% to 40% implies continued sequential expansion.

Management expects gross margin to expand throughout 2026, with manufacturing utilisation, favourable product mix from the Treo platform, and ongoing fab rationalisation serving as the primary levers. The full-year revenue forecast stands at USD 6.29 billion for FY2026, rising to USD 6.94 billion in FY2027

Conclusion

Onsemi's first-quarter 2026 results offer a substantive case that the company's structural repositioning is beginning to generate measurable financial returns. Revenue growth, margin expansion, and AI data centre momentum all came in above expectations. The Q2 guidance, issued above analyst consensus, extends that narrative into the near term. Longer-dated catalysts, including the GaN product ramp, Treo proliferation into mass-market channels, and the 900-volt EV architecture transition, remain on track per management.

Risks remain. Input cost pressures have not yet been fully offset by pricing actions, the automotive replenishment cycle has not materialised, and the stock's sharp appreciation this year narrows the margin of safety at current valuations. A disciplined monitoring of utilisation rates, gross margin trajectory, and Treo design win conversion will be essential to assess whether the structural thesis continues to hold through the second half of 2026.
