Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 5% year-over-year, driven by higher demand in the automotive and industrial end-markets, particularly within the PSG segment (+14%).
- Margin Expansion: Gross margin improved significantly by 18.2 percentage points to 38.5%. This was primarily due to the absence of $237.7 million in excess/obsolete inventory charges and a $43.9 million consumables write-off that occurred in Q1 2025 but did not recur.
- Restructuring Charges: "Restructuring, asset impairments and other, net" decreased to $329.3 million from $539.3 million in the prior year. This quarter included $147.0 million in non-cash asset impairments and $20.2 million in restructuring severance costs related to the 2026 Manufacturing Realignment Program.
- Segment Performance: The ISG segment returned to profitability with a 39.4% gross margin, compared to a (55.6)% margin in Q1 2025, largely due to the absence of prior-year inventory charges.
Guidance, Outlook, and Risks
- Manufacturing Realignment: The company continues a multi-year program to align capacity with long-term needs. In Q1 2026, this included a workforce reduction of approximately 650 employees and impairments of manufacturing equipment in South Korea and the Czech Republic.
- Capital Allocation: The company repurchased 5.7 million shares for $348.6 million. Approximately $5.7 billion remains available under the New Share Repurchase Program approved in November 2025.
- Capital Expenditures: CapEx was approximately 1% of revenue for the quarter. Management expects full-year 2026 CapEx to be approximately 5% of revenue.
- Legal Proceedings: The company is defending a securities class action regarding its SiC business (Hubacek v. On Semiconductor Corp.). The court granted the company's motion to dismiss the second amended complaint in July 2025, but a third amended complaint was filed in August 2025. The company believes it has strong defenses.
- Liquidity: Management believes cash on hand, operating cash flows, and the $1.5 billion Revolving Credit Facility are sufficient to meet needs for the next 12 months and beyond.
Investor Verification Checklist
- Inventory Valuation: Verify the sustainability of the gross margin improvement by monitoring future inventory levels and potential write-offs, given the significant one-time charges in the prior year.
- Restructuring Execution: Track the progress of the 2026 Manufacturing Realignment Program, specifically the disposal of held-for-sale assets and the realization of cost savings.
- Legal Exposure: Monitor the status of the SiC-related securities litigation and any potential financial impact from settlements or judgments.
- Working Capital: Analyze the decline in operating cash flow ($239.1M vs $602.3M) driven by working capital changes to ensure it is not a recurring trend.
- Debt Maturities: Note the $804.9 million maturity of the 0% Notes in 2027 and the company's strategy for refinancing or conversion.
