Amendment Description This Amendment No. 1 to Form 10-K (this “Amendment No.1” or “Form 10-K/A”) is being filed to amend the Annual Report on Form 10-K for the fiscal year ended December 31, 2024, of CKX Lands, Inc., a Louisiana corporation, originally filed March 25, 2025, with the United States Securities and Exchange Commission, or the “SEC” (the “Original Filing”). We are filing this Amendment No. 1 to include as an exhibit to the Original Filing the consent of our independent registered public accounting firm to the incorporation by reference in our Registration Statement on Form S-8, No. 333-256589 (the “Registration Statement”), of their report dated March 25, 2025 with respect to our financial statements that was included in the Original Filing.   Part IV (Items 15 and 16) of the Original Filing is hereby deleted in its entirety and replaced with the following Part IV set forth below, including to add new exhibits. As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 are attached hereto as Exhibit 31.3 and Exhibit 31.4, respectively. Because no financial statements are included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Also, we are not including the certifications under Section 906 of Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment No. 1. Further, we are amending the cover page to update the number of ordinary shares outstanding.   Except as described above, no other changes have been made to the Original Filing. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and our other filings with the SEC. The Original Filing continues to speak as of its date, and we have not updated the disclosures contained in the Original Filing to reflect any events that occurred after the filing of the Original Filing.   Except where the context indicates otherwise, the terms “Registrant,” “Company,” “we,” “us,” or “our” refer to CKX Lands, Inc.
