Holland, Michigan, April 28, 2011 - Macatawa Bank Corporation (Nasdaq: MCBC) today announced its results for the first quarter of 2011, marking the Company's fourth consecutive quarter of profitability and continued improvement in all key capital and operational ratios.

Macatawa reported net income available to common shares of $1.3 million, or $0.07 per diluted share, in the first quarter 2011 compared to net loss of $21.1 million, or $1.19 per diluted share, for the first quarter 2010. This improvement continues a trend experienced over the last three quarters of 2010 with the Company reporting net income of $835,000 in the fourth quarter 2010, $703,000 in the third quarter 2010 and $1.7 million in the second quarter 2010.

"Since I accepted the role of Chairman of Macatawa Bank Corporation in late 2009," said Richard L. Postma, "we have been cautious not to place undue emphasis on what may be considered a positive or negative quarter or on apparent trends. Our focus is broader and long-term. Our goal is to return Macatawa Bank to consistent profitability and to be an exceptional community bank in West Michigan. Nonetheless, we are pleased with our first quarter profit, which continued the momentum the Company achieved in the last three quarters of 2010. The first quarter of 2011 represented our fourth consecutive quarter of profitability, with continued improvements in every key capital and performance metric. Net charge-offs for the first quarter of 2011 were at our lowest level since the third quarter of 2008. Nonperforming loans were at our lowest level since the third quarter of 2007."

Mr. Postma continued, "These significant achievements are a result of our efforts beginning in late 2009 to identify and address asset quality and procedural weaknesses. We believe the improvements in our credit quality metrics reflect improved stability in our loan portfolio, real estate values and the Michigan economy in general. It is our belief that the work we have done since late 2009, coupled with our improving credit quality metrics, position us to continue down a path toward sustained profitability."

Mr. Postma continued, "Regulatory capital ratios at March 31, 2011 were at the highest level since the first quarter of 2009 and have now returned to levels ordinarily required for banks to be categorized as "well capitalized" under regulatory standards. As a result, the amount of capital we need to contribute to the Bank to comply with our Consent Order has decreased from $43.2 million at March 31, 2010 to $14.0 million at March 31, 2011. Our goal remains to reach compliance with the Consent Order, and we continue to work closely with regulators in our efforts to do so."

Mr. Postma concluded, "We remain focused on further improvements and our long-term goals. We must continue to improve the Bank's capital ratios, and we must significantly reduce our level of other-real-estate-owned and non-performing loans. Through the commitment of our Board of Directors, management and employees, we intend to continue our efforts to build accountability, confidence and performance in Macatawa Bank and serve West Michigan as an exceptional community bank."

Over the past year and a half, under the direction of the Board of Directors, the Company has navigated a difficult banking environment and critical transition period. Under this leadership, the Bank improved business and banking principles, added experienced personnel, added new directors with financial and accounting expertise, enhanced corporate governance, and bolstered the Bank's risk management functions by adding key individuals in its Special Assets and Loan Review groups. During the first quarter of 2011, the Company appointed a seasoned banker as head of commercial banking and added specialists to its Special Assets group to focus on the disposition of other real estate owned properties.

Operating Results

Net interest income for the first quarter 2011 totaled $11.6 million, a decrease of $686,000 from the fourth quarter 2010 and a decrease of $1.4 million from the first quarter 2010. Net interest margin was 3.22 percent, down 16 basis points from 3.38 percent on a consecutive quarter basis, and was at the same level as the first quarter 2010. Late in the fourth quarter of last year and throughout the first quarter of this year the Bank experienced a sharp seasonal increase in deposit balances. While creating a strong liquidity position for the Bank, the excess seasonal deposits have the short-term impact of decreasing net interest margin.

Average interest earning assets for the first quarter 2011 decreased $14.4 million from the fourth quarter 2010 and were down $211.5 million from the first quarter 2010, negatively impacting net interest income. The decreases in assets reflected the Bank's continued focus on capital ratio maintenance, liquidity improvement, and reduction in credit exposure within certain segments of its loan portfolio.

Non-interest income of $3.7 million for the first quarter 2011 was down $829,000 from the fourth quarter 2010, and up $211,000 from the first quarter 2010. The decrease from the fourth quarter 2010 was primarily due to a $574,000 gain in the fourth quarter 2010 on the sale of a property that had been held for branch expansion. The increase over the prior year period was primarily due to a higher level of gains on sales of mortgage loans in the first quarter 2011.

Non-interest expense was $15.4 million for the first quarter 2011, compared to $15.6 million for the fourth quarter 2010 and $17.9 million for the first quarter 2010. The largest increase in non-interest expense related to costs associated with the administration and disposition of problem loans and non-performing assets, which were up $238,000 in the first quarter 2011 compared to the fourth quarter 2010 and down $1.1 million compared to the first quarter 2010. FDIC insurance assessments remained elevated at $1.0 million as a result of higher assessment rates implemented by the FDIC, and were substantially unchanged compared to the last quarter of 2010 and down slightly from $1.2 million in the first quarter 2010.

When excluding nonperforming asset costs and FDIC assessments, non-interest expense was $10.0 million for the most recent quarter, down $300,000 from $10.3 million in the fourth quarter 2010 and down $1.1 million from $11.1 million for the first quarter 2010. These costs continue to trend downward as a result of the Company's ongoing focus on expense management and its efforts to scale its operations to respond to the impact of the prolonged economic weakness.

Asset Quality

As a result of the continued decline in net charge-offs, consistent improvements in nonperforming loans and delinquencies over the past four quarters, and continued shrinkage of the loan portfolio, the provision for loan losses for the first quarter 2011 was a negative $1.45 million. The provision for loan losses was $400,000 for the fourth quarter 2010, $550,000 in the third quarter 2010, $1.8 million in the second quarter 2010 and $19.7 million in the first quarter 2010. Net charge-offs for the first quarter 2011 were at the lowest quarterly level since 2008 at $3.6 million, compared to $5.2 million for the fourth quarter 2010, $4.6 million for the third quarter 2010, $6.3 million for the second quarter 2010 and $13.6 million for the first quarter 2010.

The allowance for loan losses of $42.3 million was 3.67 percent of total loans at March 31, 2011, compared to 3.90 percent of total loans at December 31, 2010 and 4.23 percent at March 31, 2010. While this overall loan coverage ratio declined, the more important ratio of loan loss reserve coverage to nonperforming loans increased significantly to 75.48 percent at March 31, 2011, compared to 62.93 percent of December 31, 2010 and 59.27 percent at March 31, 2010. This ratio is at its highest level since June 2007.

At March 31, 2011, the Company's non-performing loans were $56.1 million, representing 4.86% of total loans, the lowest level since the third quarter of 2007. This compares to $75.4 million (6.19 percent of total loans) at December 31, 2010, $84.4 million (6.61 percent of total loans) at September 30, 2010 and $102.5 million (6.88% of total loans) at March 31, 2010. Other-real-estate-owned is higher at $65.0 million at March 31, 2011 compared to $58.0 million at December 31, 2010 and $45.8 million at March 31, 2010. These balances have increased as our problem loans have migrated through the normal collection process. However, the total of nonperforming loans and other-real-estate-owned has decreased by $27.3 million from March 31, 2010 to March 31, 2011.

A break-down of non-performing loans is shown in the table below.

Total non-performing assets were $121.1 million, or 7.78 percent of total assets, at March 31, 2011. A break-down of non-performing assets is shown in the table below.

Balance Sheet, Liquidity and Capital

Total assets were $1.56 billion at March 31, 2011, a decrease of $21 million from $1.58 billion at December 31, 2010. Total loans were $1.15 billion at March 31, 2011, down $63 million from $1.22 billion at December 31, 2010.

Commercial loans decreased by $47.5 million, representing the majority of the decrease in total loans since December 31, 2010. The commercial real estate portfolio was reduced by $43.4 million as the Company continued its efforts to reduce exposure in these segments. Commercial and industrial loans declined by only $4.0 million. Of the decline in commercial real estate loans, $35.3 million was in loans to residential developers, the portfolio that has caused the majority of stress within the Company's loan portfolio.

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

The reduction in loans since year-end 2010 allowed the Company to continue its reduction of wholesale funding. In the first quarter 2011, wholesale funding, including out-of-market deposits acquired through brokers and other borrowed funds, decreased by $16.7 million. Total deposits were $1.26 billion at March 31, 2011, down $12.0 million from $1.28 billion at December 31, 2010, as the Bank continued to encourage run-off of brokered deposits and higher priced local certificates of deposit. Customer deposit accounts remain fully insured to the highest levels available under the FDIC insurance programs.

The Bank's capital ratios continued to improve in the first quarter 2011. At March 31, 2011, all of the regulatory capital ratios for Macatawa Bank were maintained at levels in excess of those ordinarily required to be categorized as "well capitalized" under applicable regulatory capital guidelines, but the Bank did not have capital at levels required by its Consent Order. At March 31, 2011, the Bank's total risk-based capital ratio of 10.42 percent was above the 10.0 percent minimum ordinarily required to be categorized as "well capitalized" and below the 11.0 percent minimum required by the Consent Order. This ratio has steadily improved since March 31, 2010 when it was 8.14 percent. Because the Bank is subject to the Consent Order, it cannot be categorized as "well capitalized" regardless of actual capital levels. Significant improvement has been made with respect to the Bank's regulatory capital ratios over the past year which reduces the amount of capital the Company needs to raise in order to comply with the Consent Order.
