Holland, Michigan - Macatawa Bank Corporation Reports Record Third Quarter Earnings and Assets Over $2 Billion

Macatawa Bank Corporation today announced net income for the third quarter of 2006. Net income for the quarter was a record $6.01 million, an 8% increase over third quarter 2005 net income of $5.55 million. Diluted earnings per share totaled $0.36 for the quarter compared to $0.34 for the third quarter of 2005. The results for the third quarter represent a 1.20% ROA and a 15.69% ROE. Net income for the first nine months of 2006 increased 11% to $16.99 million, or $1.03 per diluted share, as compared to net income of $15.35 million, or $0.93 per diluted share, for the first nine months of 2005. The results for the first nine months of 2006 represent a 1.16% ROA and 15.20% ROE.

“Macatawa achieved two major milestones during the third quarter, as quarterly earnings exceeded $6 million for the first time and total assets passed the $2 billion mark. Surpassing $2 billion in total assets is especially significant considering we began less than nine years ago,” commented Ben Smith, Chairman and CEO. Macatawa now has over 460 employees, 24 full service branch locations, and a complete line of personal, business and investment services. Its market extends throughout Ottawa and Kent counties and into Allegan County. “In Ottawa County, we are now the #1 Bank in total deposit market share. We are proud of the lasting franchise we have developed,” added Mr. Smith.

Total assets increased $216.5 million from September 30, 2005 to $2.04 billion at September 30, 2006. Over the same twelve month period, total loans increased $170.9 million to $1.68 billion and total deposits increased $175.3 million to $1.63 billion at September 30, 2006. For the quarter, core deposits grew $86 million, 27% on an annualized basis. Macatawa also opened over 1,000 net new deposit accounts during the quarter. “Generating growth by gathering deposit balances within our markets remains a hallmark of our success,” stated Mr. Smith. “This outstanding growth in a difficult market is a tribute to the exceptional quality of our people and their commitment to community banking. Their focus on identifying the needs of our customers and recommending appropriate financial solutions has been the key to our success,” added Mr. Smith.

Third quarter net interest income totaled $17.0 million, an increase of $978,000 compared to the third quarter of 2005. The improvement in net interest income was driven primarily by an increase in average earning assets offset by a decline in the net interest margin. Average earning assets grew by 10% or $168.5 million from $1.70 billion for the third quarter of 2005 to $1.87 billion for the third quarter of 2006. The net interest margin was 3.62% for the quarter, down 12 basis points from 3.74% for the second quarter of 2006 and 14 basis points from 3.76% for the third quarter of 2005. The cost of funds rose more than the yield on assets and is the primary reason for the decline in net interest margin. Deposit customers continue to shift into higher costing deposit products within the generally high rate environment. At the same time, the increase in the yield on loans began to moderate during the quarter as the Federal Reserve Bank halted its series of 17 straight rate increases.

Non-interest income was $3.5 million for the third quarter of 2006 compared to $3.6 million for the third quarter of 2005. Non-interest income for the prior year quarter included a $148,000 gain on the sale of a commercial property. In addition, mortgage sale gains decreased by $332,000 compared to the prior year quarter resulting from both a challenging real estate market and interest rate environment. However, this decline was offset by increases in revenue from trust and other financial services as the Company continues to gain new customers in these service areas. Non-interest expense was $11.3 million for the quarter, remaining flat when compared to $11.3 million for the second quarter of 2006 and up slightly compared to $10.7 million for the third quarter of 2005. For the past three quarters, the Company has been able to manage its overhead costs at just over $11.0 million per quarter despite its continued commitment to expansion. Compared to the prior year quarter, the majority of the increase in non-interest expense relates to an increase of $438,000 in salaries and benefits. This increase included $174,000 in stock option compensation expense related to the adoption of FAS 123, Revised beginning January 1, 2006. The remainder of the increase was related to additional staffing in each line of business and in support departments consistent with growth of the Bank.

The provision for loan losses was $490,000 for the quarter, down from $855,000 for the third quarter of 2005. A decline in net charge-offs and slightly slower growth in total loans for the quarter resulted in the decline in the provision for loan losses. Annualized net charge-offs were 0.05% of average loans for the quarter, down from 0.09% for the third quarter of 2005. Non-performing assets to total assets increased slightly to 0.42% at September 30, 2006 compared to 0.38% at June 30, 2006 and 0.28% at September 30, 2005. The allowance for loan losses represents 1.33% of total loans at September 30, 2006.

The Company remained well-capitalized at September 30, 2006 with a total risk-based capital ratio of 10.95%.

“The banking environment continues to be challenging. Long-term rates are now lower than short-term rates, making it difficult to grow revenue through improved profit margins. Despite this challenging business climate, our third quarter results were favorable and we our confident our commitment to community banking will continue to ensure our long-term success,” concluded Mr. Smith.
