☒ Rule 13p-1 under the Securities Exchange Act (17 CFR 240-13p-1) for the reporting period January 1 to December 31, 2024.

SECTION 1 – CONFLICT MINERALS DISCLOSURE

ITEM 1.01 CONFLICT MINERALS DISCLOSURE AND REPORT

This Specialized Disclosure Report on Form SD of Electro-Sensors, Inc. (“ESI”) for the year ended December 31, 2024 is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (“Rule”). Numerous terms in this Form SD are defined in the Rule, the instructions to Form SD, and the SEC Release relating to the Rule (Release No. 34-67716 dated August 22, 2012). Unless otherwise defined in this Form SD or the attached Conflict Minerals Report, such terms have the meanings ascribed to them in these sources.

The report presented herein is not audited as the Rule provides that if a registrant’s products are “DRC conflict undeterminable”, the Conflict Mineral Report is not subject to an independent private sector audit.

ESI has determined that certain Conflict Minerals, tantalum, tin, tungsten, and gold, are necessary to the functionality or production of the products ESI manufactures or contracts to manufacture.

ESI conducted a reasonable country of origin inquiry regarding Conflict Minerals utilized in its products. That reasonable country of origin inquiry was designed to determine whether those Conflict Minerals present in ESI products originated in the Covered Countries or arose from recycled or scrap sources. That reasonable country of origin inquiry revealed that ESI is unable to determine if necessary Conflict Minerals used in our products originated from the Covered Countries, but ESI has no reason to believe that its necessary Conflict Minerals may have originated in the Covered Countries.

Accordingly, ESI exercised due diligence regarding the source and chain of custody of its necessary Conflict Minerals through utilization of a nationally recognized due diligence framework, as more particularly described in ESI’s Conflict Minerals Report furnished with this Form SD as Exhibit 1.01.

ITEM 1.02 EXHIBIT

ESI’s Conflict Minerals Report for the reporting period of January 1 to December 31, 2024 is furnished as Exhibit 1.01 and is also available at the Company’s website at www.electro-sensors.com under About/Investor Information/Corporate Governance.

SECTION 2 – EXHIBITS

ITEM 2.01 EXHIBITS
