Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Conflict Minerals Disclosure

Graham Corporation (“we,” “us” or “our”) has determined that from January 1, 2025—December 31, 2025, certain Conflict Minerals (as defined by Item 1.01(d)(3) of Form SD) were necessary to the functionality and/or production of products that we manufactured or that we contracted to manufacture. Based on a reasonable country of origin inquiry, we have no reason to believe that such Conflict Minerals originated in the Democratic Republic of the Congo or an adjoining country sharing an internationally recognized border with the Democratic Republic of the Congo (together, “Covered Countries”).

We undertook our reasonable country of origin inquiry by sending a vendor questionnaire to each of our vendors that has been active within the past year, including new vendors. The questionnaire solicited information regarding each such vendor’s use of Conflict Minerals, its due diligence procedures with respect to its supply chain and the country of origin of any such Conflict Minerals. In some instances, we followed up with our vendors to obtain their responses. We also maintain a policy that we take vendor responses to the questionnaire into account when assessing continuing vendor relationships. We also attach the questionnaire to all purchase orders.

None of the elicited responses implicated any of the Covered Countries as the country of origin for any Conflict Minerals used by us in products that we manufactured or contracted to manufacture during the period covered by this specialized disclosure report. Based on our review of the responses, we have no reason to believe that Conflict Minerals provided by our vendors may have originated in the Covered Countries.

This Conflict Minerals Disclosure as well as our Conflict Minerals Policy is available on our website at https://ir.grahamcorp.com/corporate-governance/governance-documents.

Item 1.02 Exhibit

Based on the results of our reasonable country of origin inquiry described in Item 1.01 above, we are not required to file a Conflict Minerals Report.
