Amendment Description	Macatawa Bank Corporation (the “Company”, “our”, "we", "us" or “Macatawa”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to its Annual Report on Form 10-K for the year ended December 31, 2023, which was originally filed on February 15, 2024 (the “Original Filing”), solely to include the information required by Part III of Form 10-K of the Original Filing and not included in the Original Filing. This information was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above referenced items to be incorporated in the Form 10-K by reference from the Company’s definitive proxy statement if such statement is filed no later than 120 days after the Company’s fiscal year end. This Amendment amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the Original Filing. In addition, the reference on the cover of the Original Filing to the incorporation by reference of our definitive proxy statement into Part III of the Original Filing is hereby deleted. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Form 10-K/A also contains certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto. Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Except as described above, this Amendment does not modify or update the disclosure in, or exhibits to, the Original Filing in any way, and the parts or exhibits of the Original Filing which have not been modified or updated are not included in this Amendment. Furthermore, this Form 10-K/A does not change any previously reported financial results, nor does it reflect events occurring after the filing date of the Original Filing. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the Original Filing was filed. This Amendment continues to speak as of the date of the Original Filing, and except as expressly set forth in this Amendment, does not reflect events occurring after February 15, 2024, the filing date of the Original Filing, or modify or update those disclosures that may have been affected by subsequent events. Accordingly, this Amendment should be read in conjunction with the Original Filing and the Company’s other filings made with the Securities and Exchange Commission since the filing of the Original Filing, including amendments to those filings, if any.
