Item 8.01. Other Events.

As previously announced, on October 29, 2025, First Mid Bancshares, Inc. ( “First Mid”) and Star Sub LLC, a newly formed Iowa limited liability company and wholly-owned subsidiary of First Mid (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Two Rivers Financial Group, Inc., an Iowa corporation (“Two Rivers”), pursuant to which, among other things, First Mid agreed to acquire 100% of the issued and outstanding shares of Two Rivers pursuant to a business combination whereby Two Rivers will merge with and into Merger Sub, whereupon the separate corporate existence of Two Rivers will cease and Merger Sub will continue as the surviving company and a wholly-owned subsidiary of First Mid (the “Merger”).

On February 24, 2026, at a special meeting of the stockholders of Two Rivers, Two Rivers’ stockholders voted to approve the Merger. Subject to the satisfaction of customary closing conditions in the Merger Agreement, the Merger is anticipated to be completed on February 28, 2026.
