Conflict Minerals Report

For the Year Ended December 31, 2025

This conflict minerals report for the year ended December 31, 2025 (this "Report"), is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934, as amended (the "Rule"). The Rule was adopted by the Securities and Exchange Commission ("SEC") to implement reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Act"). The Rule imposes certain reporting obligations on SEC registrants whose manufactured products contain conflict minerals that are necessary for the functionality or production of their products. "Conflict minerals" are defined as cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which are limited to tin, tantalum, tungsten, and gold ("3TG"). These requirements apply to registrants, regardless of the geographic origin of the conflict minerals and whether or not they fund an armed group.

If a registrant has reason to believe that any of the conflict minerals in its supply chain may have originated in the Democratic Republic of the Congo or an adjoining country (the "Covered Countries"), or if it is unable to determine the country of origin of those conflict minerals, then the registrant must conduct due diligence on the conflict minerals' source and chain of custody. The registrant must annually submit a Conflict Minerals Report ("CMR") as an exhibit to Form SD that includes a description of those due diligence measures.

Based on the guidance provided by the SEC's Division of Corporation Finance in its "Statement on the Effect of the Recent Court of Appeals Decision on the Conflict Minerals Rule," dated April 29, 2014, and its "Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule," dated April 7, 2017, we have not provided an independent private sector audit of this Report.
