QUAKER CHEMICAL CORP

We at Quaker Houghton understand that we have a great responsibility to see beyond the challenges of today to promote sustainability with our communities, colleagues and customers. At its core, sustainability focuses attention on meeting the needs of the present while managing environmental, social and economic concerns in a responsible and ethical manner so that future generations are healthy and successful.

Following a sustainability impact materiality assessment that we completed in 2020 (which involved many stakeholders including investors, customers, suppliers and colleagues), in August of 2021 we launched our Sustainability Program. The program provides areas of strategic focus under a framework of new initiatives to be implemented, as well as a roadmap to build them into a fully integrated management approach. Then in 2024, the Company initiated its first double materiality

assessment which involved the identification of our material sustainability impacts, risks and opportunities through both financial materiality and impact materiality perspectives.

The four pillars of our strategy are 1) Innovating Together for a Better Tomorrow, 2) Protecting Our Planet, 3) Empowering Our Colleagues and Communities, and 4) Sourcing Our Materials Responsibly. In 2025, we made significant progress on our strategy by focusing on the impacts, risks, and opportunities identified in the 2024 double materiality assessment, and anticipate disclosing those results in the 2025 Sustainability Report.

Our Sustainability Program is subject to Board oversight, primarily delegated to the Board’s Sustainability Committee, which consists entirely of non-management directors, all of whom have substantial relevant industry experience as well as expertise in sustainability matters. The Executive Leadership Team (“ELT”) has operational leadership and responsibility in this area as each portion of our strategy has an executive sponsor providing oversight. Both groups were active in 2025 and provided oversight on strategy, performance progress and measurement, disclosure alignment and governance related to sustainability matters.

We publish our Sustainability Report annually on our website. Our 2024 Sustainability Report is available on our website athttps://www.quakerhoughton.com/sustainability, and our 2025 Sustainability Report is expected to be available on our website later this year. Information in these reports and on our website is not incorporated into this proxy statement. Our 2025 Sustainability Report will be aligned to the Sustainability Accounting Standards Board (SASB) Chemical Industry Standards, Global Reporting Initiative (GRI), and the Task Force on Climate-related Financial Disclosure (TCFD), globally recognized disclosure frameworks to help us ensure that our disclosure is meaningful and transparent.
