ITEM 2.01 COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS

Effective July 1, 2026, Richmond Mutual Bancorporation, Inc. (‘Richmond’), the holding company of First Bank Midwest (formerly First Bank Richmond), completed its previously announced merger with The Farmers Bancorp, Frankfort, Indiana (‘Farmers’), the holding company of The Farmers Bank, pursuant to the Agreement and Plan of Merger, dated November 11, 2025 (the ‘Merger Agreement’). Under the terms of the Merger Agreement, Farmers merged with and into Richmond (the ‘Merger’), with Richmond as the surviving corporation. Immediately following the Merger, The Farmers Bank merged with and into First Bank Richmond (the ‘Bank Merger’). In connection with the Bank Merger, First Bank Richmond was renamed First Bank Midwest and continued as the surviving bank.

Each share of common stock of Farmers outstanding immediately prior to the effective time of the Merger (the ‘Effective Time’) converted into the right to receive 3.40 shares of Richmond common stock, par value $0.01 per share (‘Richmond Common Stock’) (together with cash, without interest, in lieu of any fractional shares, collectively, the ‘Merger Consideration’), based on an exchange ratio of 3.40 (the ‘Exchange Ratio’).

At the Effective Time: (i) each unvested restricted stock unit award of Farmers automatically vested, and the underlying shares became outstanding and entitled to receive the Merger Consideration, less applicable tax withholding; and (ii) each unvested performance share award of Farmers was terminated and settled in cash based on the target award levels immediately prior to the Effective Time.

As a result of the Merger, at the Effective Time, Richmond issued a total of 6,254,357 shares of Richmond Common Stock, before giving effect to cash paid in lieu of fractional shares.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, included as Exhibit 2.1 to the Current Report on Form 8-K that Richmond filed on November 12, 2025, and incorporated herein by reference. The issuance of shares of Richmond common stock in connection with the Merger was registered under the Securities Act of 1933, as amended, pursuant to a registration statement on Form S-4 (File No. 333-294527) filed by Richmond with the Securities and Exchange Commission (the ‘SEC’) and declared effective on April 3, 2026 (the ‘Registration Statement’). The joint proxy statement/prospectus included in the Registration Statement (the ‘Joint Proxy Statement/Prospectus’) contains additional information about the Merger Agreement and the transactions contemplated thereby.
