Read from ON Semiconductor’s annual reports (10-K for 2025, 10-K for 2024, 10-K for 2023) and the financial data it files with the SEC, as of 2026-02-09. Every quotation is word for word from the filing linked beside it; how these pages are built and checked. The full record is in its company data sheet.
