Explanatory Note

Mercantile Bank Corporation (the "Company") is filing this Amendment No. 1 (this "Amendment") to its Current Report on Form 8-K originally filed with the Securities and Exchange Commission (the "Commission") on July 22, 2025 (the "Original Report"), to select the box on the cover page indicating that this filing is intended to simultaneously satisfy the filing obligations of Rule 425 of the Securities Act. The text below in this Amendment otherwise remains unchanged from the Original Report.

Item 1.01

Entry into a Material Definitive Agreement.

On July 22, 2025, Mercantile Bank Corporation (“Mercantile”) and Eastern Michigan Financial Corporation (“EFIN”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which EFIN will merge with and into an acquisition subsidiary of Mercantile, with the acquisition subsidiary as the surviving corporation (the “Merger”). Following the Merger, Mercantile will operate for a period of time as a two-bank holding company. The newly acquired Eastern Michigan Bank will operate alongside Mercantile’s existing bank, Mercantile Bank, until the first quarter of 2027 at which time Mercantile plans to consolidate Eastern Michigan Bank into Mercantile Bank.

Under the terms of the Merger Agreement, each outstanding share of EFIN’s common stock will be converted into the right to receive $32.32 in cash and 0.7116 shares of Mercantile common stock, for an aggregate transaction value of approximately $95.8 million.

The Merger Agreement has been approved by the boards of directors of each of Mercantile and EFIN. The parties anticipate that the Merger will close in the fourth quarter of 2025, subject to receiving approval of the Merger Agreement by EFIN’s shareholders and applicable regulatory agencies, and the fulfillment of other customary closing conditions.

The Merger Agreement contains customary representations and warranties from each of Mercantile and EFIN with respect to its and its subsidiaries’ businesses. In addition, the Merger Agreement includes customary covenants, including, among others, (i) covenants by each party relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the effective time of the Merger, (ii) covenants by EFIN relating to EFIN’s obligation to call a meeting of its shareholders to approve the Merger Agreement, (iii) a covenant by EFIN, subject to certain exceptions, to recommend that its shareholders approve the Merger Agreement and (iv) covenants regarding exclusivity.

The Merger Agreement may be terminated under certain conditions, including, among others, if the closing of the Merger has not occurred by June 30, 2026. In addition, prior to obtaining shareholder approval of the Merger, EFIN may terminate the Merger Agreement under certain circumstances, including the good faith determination by its boa

In addition, prior to obtaining shareholder approval of the Merger, EFIN may terminate the Merger Agreement under certain circumstances, including the good faith determination by its board of directors that it has received an unsolicited bona fide “superior proposal,” which remains a superior proposal after any proposed modification of the Merger Agreement, if any, by Mercantile. In addition, Mercantile may terminate the Agreement if (i) EFIN fails to hold its shareholder meeting to approve the Merger Agreement within the time frame set forth in the Merger Agreement, or (ii) if EFIN’s Board of Directors makes a Company Adverse Recommendation (as defined in the Merger Agreement).
