Conflict Minerals Report

For the Reporting Period from January 1, 2025, to December 31, 2025

Introduction

This Conflict Minerals Report ("Report") of Bruker Corporation and its consolidated subsidiaries for the reporting period from January 1, 2025, to December 31, 2025 ("Reporting Period") has been prepared pursuant to Rule 13p-1 (the "Rule") promulgated under the Securities Exchange Act of 1934, as amended. The Rule requires disclosure of certain information by a company that manufactures, or contracts to manufacture, products that contain minerals specified in the Rule as "conflict minerals" that are necessary to the functionality or production of those products. For purposes of the Rule, "conflict minerals" include gold, columbite-tantalite (coltan), cassiterite, and wolframite and their derivatives, which are limited to tantalum, tin and tungsten. During the Reporting Period, we manufactured, or contracted to manufacture, certain products described below for which conflict minerals are necessary for their functionality or production.

We have adopted a Conflict Minerals Policy, which is publicly available at www.bruker.com under "About" in "Investor Relations/Corporate Governance/Governance Documents." This Report describes our due diligence measures on the source and chain of custody of conflict minerals necessary to the products we manufactured, or contracted to manufacture during the Reporting Period, our efforts to determine the mine or location of origin of the necessary conflict minerals, and, to the extent reasonably known to us, the facilities used to process the conflict minerals.
