Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Amphenol Corporation (together with its subsidiaries, the “Company” or “Amphenol”) evaluated its product lines and determined that with respect to certain products the Company manufactures or contracts to manufacture, tin, tungsten, tantalum and/or gold (“3TG”) are necessary to the functionality or production of such products. The Company conducted in good faith a reasonable country of origin inquiry and performed appropriate due diligence designed to determine whether any 3TG originated from minerals coming from the Democratic Republic of the Congo (the “DRC”) or any country that shares an internationally recognized border with the DRC, or are from recycled or scrap sources, and whether the Company’s procurement directly or indirectly finances or benefits armed conflict in the DRC or an adjoining country. Through the Company’s reasonable country of origin inquiry and due diligence process, it determined that some of its products are DRC conflict undeterminable, thus the Company has prepared a Conflict Minerals Report.

A copy of the Company’s Conflict Minerals Report is provided as Exhibit 1.01 hereto and is publicly available at: www.amphenol.com by clicking on “Sustainability”, then “Supply Chain Documents”, then “Conflict Minerals Report” and at https://www.amphenol.com/docs/conflict-minerals.
