Chemical Financial Corporation Reports Fourth Quarter 2007 Earnings

          MIDLAND, Mich., January 28, 2008 -- Chemical Financial Corporation's (Nasdaq: CHFC) Board of Directors today announced 2007 fourth quarter net income of $9.8 million, or $0.41 per diluted share, versus net income of $11.2 million, or $0.45 per diluted share, in the fourth quarter of 2006.

          Net income was $39.0 million, or $1.60 per diluted share, for the twelve months ended December 31, 2007, compared to net income of $46.8 million, or $1.88 per diluted share, for the twelve months ended December 31, 2006.

          "Although net interest income increased slightly over last year's fourth quarter, a higher provision for loan losses and higher operating expenses more than offset gains in net interest income and noninterest income," said David B. Ramaker, Chairman, President and Chief Executive Officer of Chemical Financial Corporation. "Although we have no direct exposure to subprime loans, overall credit quality remains a primary concern, with nonperforming loans more than doubling during the year as Michigan's already struggling economy continued to deteriorate in tandem with the slowdown in the national economy. We continue to proactively identify and address problem credits Company-wide."

          "We continue to expect that based on initial results we are experiencing, the investments we are making in talent, training and development, which focus primarily on front line customer relationship sales and service enhancements, will generate revenue growth going forward," added Ramaker.

          The Company's previously announced retail banking reorganization, which involved realigning its 15 community bank structure into four regions while consolidating numerous back office and support functions, has been completed. During the fourth quarter of 2007, the Company incurred only $40,000 in expenses related to the completion of the reorganization, resulting in a total of approximately $1.7 million of reorganization expenses incurred during 2007.

          Total assets were $3.75 billion at December 31, 2007, down from $3.82 billion at September 30, 2007 and $3.79 billion at December 31, 2006. At December 31, 2007, total loans were $2.80 billion, down slightly from $2.81 billion at September 30, 2007 and $2.81 billion at December 31, 2006. Over the past twelve months, increases in real estate commercial and residential loans have offset declines in commercial, real estate construction and consumer loans. Investment securities were $595 million at December 31, 2007, down from $632 million at September 30, 2007 and $615 million at December 31, 2006.

          Total deposits were $2.88 billion at December 31, 2007, down from $2.97 billion at September 30, 2007 and $2.90 billion at December 31, 2006. Wholesale borrowings, solely Federal Home Loan Bank advances, totaled $150 million at December 31, 2007, up 20 percent from $125 million at September 30, 2007, although down 14 percent from $175.1 million at December 31, 2006.

          Net interest income was $33.4 million in the fourth quarter of 2007, an increase of 2.2 percent from fourth quarter 2006 net interest income of $32.7 million. The increase in net interest income was attributable primarily to an increase in net interest margin. The net interest margin (on a tax-equivalent basis) in the fourth quarter of 2007 was 3.86 percent, up from 3.73 percent in the fourth quarter of 2006, and 3.68 percent in the third quarter of 2007. The increase in net interest margin was primarily attributable to decreases in rates paid on interest-bearing liabilities exceeding decreases in rates earned on interest-earning assets, as the benefits from declines in short-term interest rates during the second half of 2007 were more fully reflected across asset and liability categories during the fourth quarter.

          The provision for loan losses was $4.5 million in the fourth quarter of 2007, compared to $2.9 million in the third quarter of 2007 and $2.6 million in the fourth quarter of 2006. For 2007, the provision for loan losses was $11.5 million, more than double the $5.2 million provision for loan losses in 2006. Net loan charge-offs were $3.4 million in the fourth quarter of 2007, compared to $0.8 million in the third quarter of 2007 and $3.8 million in the fourth quarter of 2006. For 2007, net loan charge-offs were $6.2 million, compared to $5.7 million in 2006. The increase in the provision for loan losses in the fourth quarter of 2007, as compared to the previous quarter, was attributable to higher net loan losses, higher impairment reserves and higher nonperforming loans and was also reflective of continued declines in real estate values in the markets the Company serves. The allowance for loan losses of $39.4 million at December 31, 2007 was 1.41 percent of total loans, u p from 1.36 percent of total loans at September 30, 2007 and 1.21 percent of total loans at December 31, 2006. The allowance for loan losses allocated to impaired loans was $4.6 million at December 31, 2007, compared to $3.2 million at September 30, 2007 and $0.9 million at December 31, 2006. At December 31, 2007, nonperforming loans as a percentage of total loans were 2.26 percent, up from 1.90 percent at September 30, 2007 and up substantially from 0.96 percent at December 31, 2006.

          At December 31, 2007, nonperforming assets totaled $74.5 million, up from $62.8 million at September 30, 2007 and up significantly from $35.8 million at December 31, 2006. The increase in nonperforming assets from the previous quarter end was primarily attributable to two residential real estate development loans totaling $9.3 million transferred to nonaccrual status in the fourth quarter. One loan in the amount of $3.2 million is secured by a residential condominium project located in western Michigan. At December 31, 2007, the Company established a $1 million impairment reserve on this loan, as the fair value of the collateral of this loan was determined to be less than the principal balance of the loan. The second loan in the amount of $6.1 million is secured by a luxury condominium project and marina in southwest Michigan. At December 31, 2007, the Company established a $0.27 million impairment reserve on this loan, as the fair value of the collateral of this loan wa s determined to be slightly less than the principal balance of the loan.

          The allowance for loan losses as a percent of nonperforming loans has decreased from 127 percent at December 31, 2006 to 62 percent at December 31, 2007. A significant portion of the Company's nonperforming loans at December 31, 2007 involve specific real estate commercial loans which have been analyzed and deemed to have sufficient collateral values so as not to require allocation of the allowance for loan losses to these loans.

          Total noninterest income was $10.8 million in the fourth quarter of 2007, up $0.9 million, or 9.4 percent, from $9.9 million in the fourth quarter of 2006, but down from $11.1 million in the third quarter of 2007. The increase over the prior year's quarter was primarily attributable to slightly higher service charges on deposit accounts, fees for customer services and mortgage banking revenue. The decline in noninterest income in the fourth quarter of 2007, compared to the third quarter of 2007, was primarily attributable to a decrease in other income due to noninterest income in the third quarter of 2007 including a $1 million gain on an insurance settlement received for fire damage to a branch building.

          Due in part to the expenses incurred with the Company's retail banking reorganization, as described above, operating expenses increased from $97.9 million in 2006 to $104.7 million in 2007. During the fourth quarter of 2007, operating expenses were $25.5 million, up $2.0 million, or 9 percent, from the fourth quarter of 2006, and up $0.3 million, or 1 percent, from $25.2 million in the third quarter of 2007. The Company's efficiency ratio was 56.9 percent in the fourth quarter of 2007, up from 54.4 percent in the fourth quarter of 2006, although down from 57.1 percent in the third quarter of 2007. The change in the efficiency ratio from the prior year is primarily attributable to the increase in operating expenses.

          The Corporation's effective federal income tax rate was 30.9 percent in the fourth quarter of 2007, compared to 32.0 percent in the fourth quarter of 2006, and 31.8 percent compared to 32.4 percent for the years ended December 31, 2007 and December 31, 2006, respectively. The difference between the federal statutory income tax rate and the Corporation's effective federal income tax rate is primarily a function of the proportion of the Corporation's interest income exempt from federal taxation, nondeductible interest expense and other nondeductible expenses relative to pretax income and tax credits.

          The Company's return on average assets during the fourth quarter of 2007 was 1.04 percent, down from 1.18 percent in the fourth quarter of 2006 and 1.10 percent in the third quarter of 2007. The decline in return on assets resulted in a decline in return on average equity to 7.8 percent in the fourth quarter of 2007 from 8.6 percent in the fourth quarter of 2006. At December 31, 2007, the Company's book value stood at $21.35 per share versus $20.46 per share at December 31, 2006.

          During the fourth quarter of 2007, the Company repurchased 137,700 shares of its common stock at an average price of $23.37 per share; bringing total share repurchases for the year 2007 to 1,023,000 shares. On January 22, 2008, the Board of Directors authorized management, in its discretion, to purchase up to 500,000 shares of the Corporation's common stock.

          Chemical Financial Corporation is the third-largest bank holding company headquartered in Michigan. The Company operates through a single subsidiary bank, Chemical Bank, with 129 banking offices spread over 31 counties in the lower peninsula of Michigan. At December 31, 2007, the Company had total assets of $3.75 billion. Chemical Financial Corporation common stock trades on The Nasdaq Stock Market under the symbol CHFC and is one of the issues comprising the Nasdaq Global Select Market.
