Explanatory Note

This Current Report on Form 8-K/A is being furnished to amend Items 2.02 and 9.01 of the Current Report on Form 8-K furnished on July 16, 2026 announcing the Second Quarter 2026 earnings of Commerce Bancshares, Inc. (the Company). This amendment is to fix a typographical error as described in Item 2.02 below.

Item 2.02 Results of Operations and Financial Condition

On July 16, 2026, the Company issued a press release announcing Second Quarter 2026 earnings that was furnished under Item 2.02 of this Current Report on Form 8-K as Exhibit 99.1. Additionally, a slide presentation for investors and analysts was furnished as Exhibit 99.2 to the Current Report on Form 8-K.

Subsequent to the issuance of the earnings release and furnishing with the original Form 8-K on July 16, 2026, the Company identified that the growth in assets under administration had been incorrectly described as growth over the same period in the prior year rather than growth over the prior quarter. Therefore, the Company has prepared and furnished as Exhibit 99.1 to this Current Report on Form 8-K/A a corrected earnings release for investors and analysts that highlights the Company's Second Quarter 2026 earnings. The amended earnings release corrects the description of growth in the Company’s assets under administration on the second page of the earnings release. The statement as corrected reads as follows: “Assets under administration grew $3.1 billion, or 3.4%, over the prior quarter.” Apart from the correction of this typographical error, there were no changes to the information provided in the original press release and slide presentation.

The information in this Current Report on Form 8-K/A, including the exhibits, is furnished pursuant to Item 2.02 and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities under that Section. Furthermore, the information in this Current Report on Form 8-K/A, including the exhibits, shall not be deemed to be incorporated by reference into the filings of Commerce Bancshares, Inc. under the Securities Act of 1933, as amended.

All information included in this Current Report on Form 8-K/A is available on the Company’s Internet site at https://investor.commercebank.com/news-info/financial-news-releases/default.aspx.
