Amendment Description Steele Bancorp, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which the Company filed with the Securities and Exchange Commission (the “SEC”) on March 30, 2026 (the “Original Form 10-K”). This Amendment is being filed solely to remove the reference to “(Unaudited)” from the headings to the Company’s consolidated Statements of Income, Comprehensive Income, Changes in Stockholders’ Equity and Cash Flows included in the Original Form 10-K.   Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Amendment also contains the certifications required by Section 302 of the Sarbanes-Oxley Act of 2002, which are being filed as exhibits hereto.   Except as described above, this Amendment does not amend or update any other information contained in the Original Form 10-K, and the Original Form 10-K continues to speak as of the date of the original filing. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K and the Company’s filings made with the SEC subsequent to the date of the Original Form 10-K.
