The list is long; these are the first 150 as the company lists them. From Exhibit 21 of the 10-K for 2025. Companies must list their significant subsidiaries there and may leave out smaller ones, so this is the company’s own list, not every entity it owns.
Read from Amphenol’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 2026-02-11. 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.
