Macatawa Bank Revises 2006 Q4 Results

Holland, Michigan, March 15, 2007 – Macatawa Bank Corp. (NASDAQ: MCBC) today issued revised results for the fourth-quarter and twelve-month periods ending Dec. 31, 2006.

These financial results, which were originally reported on January 15, 2007, have been revised based on information that only became available since that date. The revision reflects an additional loan loss provision of $4.7 million related to outstanding commercial loans to one borrower of $5.2 million that have become impaired. The Bank has reason to believe that the borrower will be unable to meet the repayment terms of the loans. The loans have been secured by collateral, but the collateral may not be of a sufficient value to cover the outstanding principal on these loans.

The impairment was discovered over the past week through internal investigations relating to the collateral and the borrower relationship. Macatawa Bank’s internal investigation suggests that the borrower may have made misrepresentations to the Bank regarding the loan collateral and its financial condition.

“The realization that this appears to be an intentional effort to defraud the Bank is very distressing to all of us,” said Benj. A. Smith III, chairman and CEO. “As part of our internal investigation, we have begun a review of our loan policies and procedures. As a management team, we pledge that these procedures will be tightened to prevent a recurrence.”

The additional loan loss provision will be recognized in the fourth quarter of 2006. The after-tax impact on net income is expected to be approximately $3.1 million, or $0.18 per share. As a result of this additional provision, net income for the fourth-quarter and full-year 2006 is $2.8 million and $19.8 million, respectively, instead of the $5.9 million and $22.9 million previously disclosed. Net income per diluted share for the fourth-quarter and full-year 2006 is $0.17 and $1.20, respectively, instead of the $0.36 and $1.38 per diluted share previously disclosed.

“In light of our ongoing investigation, which is still in the preliminary stage, we determined the need to revise our 2006 loan loss provision,” said Phil Koning, president. “We will aggressively seek to recover funds associated with this borrower.

“It is important to note that Macatawa Bank remains financially strong and well-capitalized. We have a solid foundation and, with the support of our shareholders and employees, will continue to grow.”

Revised financial results are attached to this press release. These results supersede the results previously disclosed in the January 15, 2007 press release.
