Item 1.01. Entry into a Material Definitive Agreement.

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”).

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each share of common stock, par value $1.00 per share, of Two Rivers issued and outstanding immediately prior to the effective time of the Merger (other than shares held in treasury by Two Rivers) will be converted into and become the right to receive 1.225 shares of common stock, par value $4.00 per share, of First Mid and cash in lieu of fractional shares, less any applicable taxes required to be withheld, and subject to certain potential adjustments. On an aggregate basis, the total consideration payable by First Mid at the closing of the Merger to Two Rivers’ shareholders and equity award holders is approximately 2,556,140 shares of First Mid common stock. Two Rivers’ outstanding stock equity awards will fully vest upon consummation of the Merger.

It is anticipated that Two Rivers’ wholly-owned bank subsidiary, Two Rivers Bank & Trust (“Two Rivers Bank”), will be merged with and into First Mid’s wholly-owned bank subsidiary, First Mid Bank & Trust, N.A. (“First Mid Bank”), at a date following completion of the Merger. At the time of the bank merger, Two Rivers Bank’s banking offices will become branches of First Mid Bank. As of September 30, 2025, Two Rivers Bank had total consolidated assets of approximately $1.1 billion, loans of approximately $901 million and total deposits of approximately $988 million.

The Merger Agreement contains customary representations and warranties of both parties and customary conditions to the parties’ obligations to close the transaction, as well as agreements to cooperate in the process of consummating the transaction. The Merger Agreement also contains provisions limiting the activities of Two Rivers and Two Rivers Bank which are outside of the usual course of business pending completion of the Merger, including restrictions on employee compensation, certain acquisitions and dispositions of assets and liabilities, and solicitations relating to alternative acquisition proposals.

The Merger is anticipated to be completed in the first quarter of 2026 and is subject to the approval of the appropriate regulatory authorities and the shareholders of Two Rivers. Certain directors and officers of Two Rivers have executed voting agreements pursuant to which they have each separately agreed to vote their shares of Two Rivers common stock in favor of approval of the Merger.

The information set forth above does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of, the contracting parties, and are qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time and investors should not rely on them as statements of fact. In addition, such representations and warranties (i) will not survive the consummation of the Merger and (ii) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement and not to provide investors with any other factual information regarding the Merger, First Mid or Two Rivers, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding First Mid, Two Rivers, their respective affiliates and their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into the documents that First Mid will file with the Securities Exchange Commission (“SEC”), including in the Forms 10-K, Forms 10-Q and other documents that First Mid files with or furnishes to the SEC.

In connection with the execution of the Merger Agreement discussed in Item 1.01 above, First Mid and Two Rivers issued a joint press release on October 30, 2025. A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.

From time to time on and after October 30, 2025, First Mid and Two Rivers intend to provide supplemental information regarding the proposed transaction to analysts and investors in connection with certain presentations. A copy of the supplementary information is attached hereto as Exhibit 99.2 and incorporated herein by reference.

The information furnished pursuant to this Item 7.01 and the related exhibits shall not be deemed "filed" by First Mid for purposes of Section 18 of the Exchange Act or incorporated by reference in any filing under the Securities Act or the Exchange Act, except as may be expressly set forth by specific reference in such filing.
