Macatawa reported net income available to common shares of $703,000, or $0.04 per diluted share, for the third quarter 2010, compared to a net loss available to common shares of $20.9 million, or $1.18 per diluted share, for the third quarter 2009 and net income of $1.7 million, or $0.10 per diluted share, for the second quarter 2010. For the first nine months of 2010, the Company's net loss available to common shares totaled $18.7 million, compared to a net loss of $57.3 million for the same period in 2009.

"We are pleased to have achieved two consecutive quarters of profitability and improvements in several capital and performance metrics," said Richard L. Postma, Chairman of Macatawa Bank Corporation. "These results are the product of hard and focused work by our people and the disciplined approach we continue to implement across the Company. But to be clear, two profitable quarters are only a beginning. We recognize that the results from the two most recent quarters are preceded by six consecutive quarters of high net losses. We must continue to focus our efforts to build accountability, confidence and performance in Macatawa Bank. Our goal remains to return to 'well-capitalized' status, and we continue to work closely with regulators in our efforts to comply with the terms of our consent order. We remain committed to doing the things necessary to achieve sustained profitability in order to serve West Michigan as a strong community bank. There is much work yet to be done."

Under the leadership of Mr. Postma and the Board of Directors, the Bank continues to implement improved business and banking principles, has added experienced personnel in both management and at the board level, has bolstered the Bank's risk management functions by adding key individuals in its Special Assets and Loan Review departments, and continues to implement new and more disciplined lending and loan risk management policies and procedures. Macatawa Bank continued its focus on improved asset quality during the third quarter by accelerating workout strategies with some of its more stressed loan customers, which resulted in significant reductions in the level of nonperforming loans at the end of the quarter.

The Company recently announced the appointment of five new Macatawa Bank Corporation Board members, further strengthening its leadership team. New directors Wayne J. Elhart, Charles C. Geenen, Birgit M. Klohs, Robert L. Herr, and Thomas P. Rosenbach each add complementary expertise to the Board of Directors.

Operating Results

Net interest income for the third quarter 2010 totaled $12.4 million, a decrease of $381,000 from the second quarter 2010 and a decrease of $757,000 from the third quarter 2009. Net interest margin was 3.22 percent, down 7 basis points from 3.29 percent on a consecutive quarter basis and up 39 basis points from 2.83 percent in the third quarter 2009.

Average interest-earning assets for the third quarter 2010 declined $39.9 million from the second quarter 2010 and declined $355.5 million from the third quarter 2009, negatively impacting net interest income. The decline in assets continues to reflect the Bank's focus on strengthening liquidity, improving capital ratios, and reducing credit exposure within certain segments.

Non-interest income of $3.7 million for the third quarter 2010 was up $92,000 from the third quarter 2009, but down $2.6 million from the second quarter 2010. The decrease from the second quarter 2010 was due to a one-time gain on the sale of securities in our portfolio recognized in the second quarter 2010.

Non-interest expense was $14.9 million for the third quarter 2010, compared to $14.3 million for the second quarter 2010 and $15.7 million for the third quarter 2009. In the most recent quarter, costs associated with the administration and disposition of problem loans and non-performing assets were $3.2 million, compared to $2.5 million in the second quarter 2010 and $3.1 million in the third quarter 2009. FDIC insurance assessments remained elevated at $1.2 million in the most recent quarter, compared to $1.2 million in the second quarter 2010 and $1.0 million in the third quarter 2009, as a result of higher assessment rates implemented by the FDIC.

When excluding non-performing asset costs and FDIC assessments, non-interest expense was $10.5 million for the most recent quarter, down from $10.6 million in the second quarter 2010 and $11.6 million in the third quarter 2009. Salaries and employee benefits were consistent with the second quarter 2010 and down $616,000 from the third quarter of 2009. This is the result of a reduction in overall staffing levels as the Company has scaled its operations to respond to the impact of the prolonged economic weakness.

Balance Sheet, Liquidity and Capital

Total assets were $1.61 billion at Sept. 30, 2010, a decrease of $219 million from $1.83 billion at Dec. 31, 2009. Total loans were $1.28 billion at Sept. 30, 2010, down $233 million from $1.51 billion at Dec. 31, 2009.

Commercial loans decreased by $199.0 million, representing the majority of the decrease since Dec. 31, 2009. The commercial real estate loan portfolio was reduced by $115.4 million as the Company continues its efforts to reduce exposure in this segment. Commercial and industrial loans declined by $83.6 million, due in part to a general decline in business activity. Of the decline in commercial real estate loans, $47.0 million of the decrease was in loans to residential developers, the portfolio that has caused the majority of stress within the Company's commercial loan portfolio.

The composition of the commercial loan portfolio is shown in the table below:

The reduction in loans since year-end 2009 allowed the Company to reduce wholesale funding, including out-of-market deposits acquired through brokers, by $139.7 million and to reduce other borrowed funds by $61.7 million. Total deposits were $1.28 billion at Sept. 30, 2010, down $136.6 million from $1.42 billion at Dec. 31, 2009, primarily from the run-off of brokered deposits. Core customer deposit accounts have remained stable throughout this year and continue to be fully insured to the highest levels available under the FDIC insurance programs.

Two of the three regulatory capital ratios for Macatawa Bank, including the tier one risk-based capital ratio and the tier one leverage capital ratio, were maintained at levels in excess of those ordinarily required to be categorized as "well capitalized" under applicable regulatory capital guidelines. Despite these ratios, the Bank was categorized as "adequately capitalized" as its total risk-based capital ratio of 9.23 percent was below the 10.0 percent minimum ordinarily required to be categorized as "well capitalized." Because the Bank is subject to a consent order, the Bank cannot be categorized as "well capitalized" regardless of its capital levels. At Sept. 30, 2010, the Bank did not have capital at levels required by its consent order. While the capital ratios were below the consent order requirements, they continued to improve in the third quarter 2010. The total risk-based capital ratio of 9.23 percent is up significantly from its lowest point of 8.14 percent at March 31, 2010.
