The Company publishes an annual sustainability report (“Sustainability Report”) to highlight our goals and areas ofprogress and success in sustainability matters, including climate-related topics. The Sustainability Report discusses our approach and progress on the environmental, social and governance (“ESG”) issues most significant to our business, including ESG-related strategies, programs, goals and metrics that demonstrate our commitment to our stakeholders. The Sustainability Report is designed to inform and engage the Company’s broad range of stakeholders, such as investors, customers, suppliers, employees and members of the communities in which we operate, among others. Our 2023 Sustainability Report was prepared in accordance with the Global Reporting Initiative (“GRI”) Standards

framework and topics identified under the Sustainability Accounting Standards Board (“SASB”) standards and outlines board and executive-level oversight of climate-related risks and opportunities identified in the Task Force on Climate-Related Financial Disclosures (“TCFD”) recommendations. The SASB standards and GRI and TCFD frameworks encourage companies to disclose climate-related topics that are important to certain interested stakeholders, even if not material for purposes ofthe U.S. securities laws. Furthermore, the materiality standards under these frameworks and other regimes we may consider are different from, and often more expansive than, the materiality standard under the U.S. securities laws. Our 2023 Sustainability Report is available on our website at https://amphenol.com/sustainability. The items discussed in our 2023 Sustainability Report have not required material capital expenditures or operating expenses, nor caused material operational challenges or risks to the Company’s business or results of operations beyond those items disclosed in Item 1A.Risk Factors within the risk factors titled “The Company may be negatively impacted by extreme weather conditions and natural catastrophic events, including those caused or intensified by climate change and global warming,” and “The Company is subject to, and may continue to be subject to, incremental costs, risks and regulations associated with efforts to combat the negative effects of climate change.”** ** Information included in our 2023 Sustainability Report and our website is not incorporated by reference in, and does not form part of, this Annual Report.
