IDEX CORP /DE/

As an embodiment of our continuing commitment to sustainability, since 2019, we have published a sustainability report every other year highlighting the various ways in which the Company, our products and our people have a positive impact. In addition to the reports, we have disclosed sustainability-related metrics every year since 2019, and our disclosures have been in alignment with the Sustainable Accounting Standards Board (SASB) sector standards since 2021.

In March 2025, we published the Company’s 2024 Sustainability Report, including updated data tables and SASB disclosures, disclosures aligned with the Task Force on Climate Related Financial Disclosures (TCFD), anddisclosures aligned with the Global Reporting Initiative(GRI). Most recently, in March 2026 we published sustainability highlights from 2025, along with updated data tables and other disclosures (collectively, the "2025 Sustainability Disclosures"). The 2025

Sustainability Disclosures, as well as prior reports and disclosures are available under the Sustainability link on our website at https://www.idexcorp.com/about-idex/idex-sustainability/.

In 2022, working with outside consultants, we conducted an updated materiality assessment as part of ensuring that we maintain a current understanding of areas of opportunity and risk related to various sustainability topics relevant to IDEX. By engaging with internal and external stakeholders, we confirmed the corporate sustainability topics most likely to impact the Company and for which the Company can make a meaningful impact. Building on that assessment, we have continued our commitment to sustainability, including to evolve our strategy to improve the impact of our operations, build out our environmental, health and safety program, and enhance our approach to responsible supply chain management. Our Chief Sustainability Officer continues to focus on developing and monitoring progress against various sustainability initiatives relevant to our businesses, managing cross-functional governance of certain sustainability topics, and, in partnership with our Finance team, continuing to prepare for pending sustainability disclosure requirements.
