Letter from the Chairman and CEO

Mr Pascal Remy

Sustainable development has become a defining challenge of the 21st century, requiring economic growth to go hand in hand with social progress and environmental protection. Among the major challenges facing our planet, access to clean water remains paramount. At SNF, our commitment to water science is unwavering; every day, all of our 9,388 employees contribute to treating, preserving, and recycling water. This shared purpose unites us as we strive to reconcile social progress and environmental transition with sustainable economic development. Water science is, more than ever, our common passion.

Through our daily commitment to advancing water science, our solutions support more than one billion people worldwide and over half a million industrial facilities. Our solutions help our customers improve operational efficiency, reduce energy consumption, and lower their carbon footprint. In 2025, 92% of SNF revenues contributed to the UN Sustainable Development Goals, primarily related to water and sanitation, climate action, and the circular economy. Our sustainability performance was recognized with the EcoVadis Platinum rating for the second consecutive year - a significant achievement, particularly in the chemical industry - confirming the robustness of our CSR strategy and reinforcing our position as a responsible industry leader.

As the world leader in water chemistry, with subsidiaries in more than 60 countries and 23 production facilities, SNF has a duty to lead by example. We remain firmly committed to our ambition of achieving carbon neutrality by 2050. To date, we have reduced our carbon footprint by 43% (Scopes 1 and 2), significantly ahead of our initial 2030 target. Beyond our own operations, we actively engage with key suppliers to support emissions reductions aligned with our objectives. Having monitored our Scope 3 emissions for several years, we have further strengthened our approach and reaffirmed our ambition by setting a new target: a 15% reduction across Scopes 1, 2, and 3 by 2030.

Supporting sustainable and responsible growth also means placing people at the heart of our priorities. Safety remains our absolute priority. Last year confirmed our excellent safety performance, placing us once again among the leaders in our industry. SNF is also committed to strengthening and promoting equal opportunity. Our culture fosters teamwork and values different backgrounds and unique perspectives. This will enable us to continue to build a safe, respectful, fair, and inclusive culture for all our employees.

Today, SNF is well positioned to continue its sustainable growth trajectory, driven by innovative products and solutions focused on water science. Our talented and diverse teams, long-standing customer partnerships, modern industrial footprint, and solid financial foundation provide the strength to pursue our long-term ambitions.

Since the publication of our first ESG report in 2006, I have witnessed with pride the steady evolution of our Group. SNF continues to grow and innovate while steadfastly adhering to its core values and its commitments to the environment and people.

A healthy planet is essential for human well-being and prosperity.

Let us continue advancing water science together.

About this report

Reporting Period & Cycle

The reporting period is from January 1 to December 31, 2025. The SNF Group’s ESG Report is published yearly, by calendar year.

Contact Point

The contact point for questions is SNF Communication. Contact details are available at www.snf.com.

Basis of Preparation

This report is prepared following the latest GRI standards. The latest versions of the topical standards have been used where applicable.

Communication on Progress of the United Nations Global Compact uses the GRI standards principles.

In our climate reporting, we follow the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD).

In addition, SNF uses the international recommendations and guidelines of the OECD and ISO 26000 as a guide when defining and selecting non-financial indicators. In selecting and measuring our key data, we take into account the recommendations of the Greenhouse Gas Protocol for Greenhouse gas emissions (GHG) and those of the European Federation of Financial Analysts Societies, the World Business Council for Sustainable Development (WBCSD), the European Chemical Industry Council (CEFIC), and the International Council of Chemical Associations (ICCA) for other non-financial indicators.

This report is also based on certain requirements of the CSDR regulation, which the SNF Group will have to comply with in 2028.

The 2025 Sustainability Report does not constitute a full set of CSRD Sustainability Statements with regard to ESRS, as adopted by the European Union. Under these European Sustainability Reporting Standards, only a complete set of CSRD Sustainability Statement comprising of all required qualitative and quantitative datapoints for the material impacts, risks and, together with explanatory notes, enables SNF Group to prepare such CSRD Sustainability Statement, in all material aspects, in accordance with the disclosure requirements under Article 8 of Regulation (EU) 2020/852.

General Report Practices

Data and indicators are reported for all our significant locations of operation per the requirements of the corresponding GRI disclosures. In 2025, this covered eight countries, representing approximately 99% of SNF Group’s total production sites: France, USA, China, India, United Kingdom, Brazil, Australia and Korea.

Whenever appropriate, we point out where information is only relevant for parts of the SNF Group. In addition, deviations are indicated in the Notes on Methodology in the Appendices section at the end of this report.

All indicators reported in tons are metric tons.

The values are expressed in terms of sales of products produced by our significant sites, with 2016 being used as the benchmark year and 100 as the basis for monitoring changes since that date.

The indicators in this report are stated following commercial rounding principles, so the totals and percentages shown may not always be exact.
