Disclosure Under Iran Threat Reduction and Syria Human Rights Act of 2012

The Company is making the following disclosure under Section 13(r) of the Exchange Act:

Protection of Intellectual Property Rights in Iran Pursuant to Specific License

As part of its intellectual property (“IP”) protection efforts, 3M has obtained and maintains patents and trademarks in Iran. Periodically, 3M pays renewal fees, through third-party IP service providers/counsel, to the Iran Intellectual Property Office (“IIPO”) for these patents and trademarks and has sought to prosecute and defend such trademarks. On April 22, 2022, the Office of Foreign Assets Control (“OFAC”) granted to 3M a specific license to make payments to IIPO at its account in Bank Melli, which was designated on November 5, 2018 by OFAC under its counter terrorism authority pursuant to Executive Order 13224. As authorized by OFAC’s specific license, in the quarter ended December 31, 2023, 3M paid $263 as part of its intellectual property protection efforts in Iran. The Company's quarterly filing for the quarter ended June 30, 2023 inadvertently omitted a renewal payment of $259 made by an IP service provider to the IIPO at its account in Bank Melli. The payment made for that quarter was $326 in total, instead of $67 as previously reported. 3M plans to continue these IP rights protection activities, as authorized under the specific license.
