Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure

This filing is being made by Waters Corporation (“Waters,” the “Company,” “we,” “us,” or “our”) for the calendar year January 1 to December 31, 2025, in accordance with Rule 13p-1 (“Rule 13p-1”) under the Securities Exchange Act of 1934 (the “1934 Act”) and Form SD (collectively, the “Conflict Minerals Rule”). Consistent with the Conflict Minerals Rule, as used herein, “Conflict Minerals” or “3TG” are tin (cassiterite), tungsten (wolframite), tantalum (columbite-tantalite or coltan) and gold. In accordance with the Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule issued by the Division of Corporation Finance of the Securities and Exchange Commission on April 7, 2017, we have not included a Conflict Minerals Report exhibit as part of this filing.

Company Overview

Waters is a specialty measurement company that operates with a fundamental purpose to advance the science that enables our customers to enhance human health and well-being. The Company has pioneered analytical workflow solutions involving liquid chromatography, mass spectrometry, thermal analysis and light scattering innovations serving the life, materials, and food sciences.

Product Scoping; Reasonable Country of Origin Inquiry (“RCOI”)

The Company determined that 3TG are used in certain components contained in the Company’s instrument systems, which are products that the Company manufactures. These 3TG are necessary to the functionality or production of the Company’s instrument systems.

As required by the Conflict Minerals Rule, the Company conducted a RCOI to determine whether any of the 3TG in the Company’s products originate in the Democratic Republic of the Congo (the “DRC”) or its adjoining countries or are from recycled or scrap sources. The Company’s due diligence program is based upon industry guidance published by the Organisation for Economic Co-operation and Development, the Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (the “OECD Guidance”).

As part of our RCOI, we asked 6,498 potentially in-scope suppliers to complete the Conflict Minerals Reporting Template (“CMRT”), developed by the Responsible Minerals Initiative (the “RMI”). The CMRT includes questions about suppliers’ uses and sourcing of 3TG, as well as questions about their own due diligence measures. All potentially in-scope suppliers received a letter from the Company’s Senior Vice President of Global Operations requesting their compliance with the annual RCOI process.

Due Diligence Program

The Company has designed its due diligence program to align with ongoing compliance with the Conflict Minerals Rule. As recommended by the OECD Guidance, the Company published a Conflict Minerals Statement, which is made available to employees, suppliers and the public on our website at https://www.waters.com/nextgen/us/en/about-waters/corporate-governance/conflict-minerals-statement.html. Among other things, the Company’s due diligence program includes the review of its worldwide supply chain for materials that contain 3TG and the evaluation of the risk that these materials are from sources that directly or indirectly finance or benefit armed groups in the DRC or an adjoining country.

The Company’s program has several elements including, but not limited to, the following:

Findings and Results

For calendar year 2025, the Company identified 6,498 potentially in-scope suppliers, an increase from 6,380 in the prior year. This increase reflects the addition of new suppliers in the ordinary course of business as well as additional supplier responses. The Company’s methodology is designed to enhance visibility into its products and their components, including components that are considered to present a lower risk of containing Conflict Minerals.

During calendar year 2025, the Company received responses from approximately 76% of the potentially in-scope suppliers contacted, representing a 3.2% increase in supplier response rate compared to the prior year. The responses received were applicable to approximately 85% of the 99,915 parts supplied by responding suppliers.

Based on the information collected through its RCOI:

As a result of the information received from its suppliers for calendar year 2025, the Company was unable to determine with certainty the country of origin of the 3TG used in its products. However, based on the information obtained and its RCOI efforts, the Company does not have reason to believe that the 3TG contained in its products originated from mines located in the DRC or adjoining countries that are controlled by armed groups.

Future Due Diligence Considerations

The Company is committed to continuing to evolve our RCOI and due diligence program. The Company intends to work to improve survey response rates from its suppliers over time. The Company also intends to continue to update our RCOI and due diligence program processes and procedures as appropriate.
