Chemical Financial Corporation Reports Second Quarter 2007 Earnings

          MIDLAND, MI., July 23, 2007 -- Chemical Financial Corporation's (Nasdaq: CHFC) Board of Directors today announced 2007 second quarter net income of $9.5 million, or $0.39 per diluted share, versus net income of $12.2 million, or $0.49 per diluted share, in the second quarter of 2006.

          Net income was $18.6 million, or $0.75 per diluted share, for the six months ended June 30, 2007, compared to net income of $24.1 million, or $0.96 per diluted share, for the six months ended June 30, 2006.

          "Michigan's struggling economy, the flattened interest yield curve environment and increased nonperforming loans continued to depress the quarter's and six month's operating results. Net interest income declined slightly and operating expenses increased due primarily to one-time charges associated with our previously announced retail banking reorganization. Additionally, credit quality, exacerbated by the state's economic condition, required a higher provision for loan losses." said David B. Ramaker, Chairman, President and Chief Executive Officer of Chemical Financial Corporation. "The Michigan economy continues to stagnate - it was the only state in the nation which did not grow in 2006. In fact, Michigan's GDP through year-end 2006 has contracted at a compound annual rate of 0.3 percent since 2004, versus the national GDP growth rate of 3.4 percent during that same period. While there are signs that the economy is bottoming out, there is little evidence of a return to growth anytime soon."

          "On the other hand, we are seeing some encouraging signs. After declining for nine consecutive quarters, our net interest margin and net interest income in the second quarter of 2007 increased over the first quarter of 2007, although remain below prior year levels. Additionally, the retail banking reorganization is on schedule. We remain committed to our

1

strategy of increasing earnings by driving revenue growth through increased products sold to existing customer households, while diligently controlling expenses," added Ramaker.

          The Company's previously announced retail banking reorganization, which involves realigning its 15 community bank network structure into four regions and consolidating numerous back office and support functions, is progressing well. During the quarter, the Company recognized reorganization costs, including severance and early retirement costs, of $1.6 million. Furthermore, the Company now anticipates that it will incur additional charges related to the reorganization in the second half of 2007 of roughly $0.7 million, which will result in higher reorganization costs than the originally anticipated and previously announced $1.5 million. The Company also projects that total annual expense savings from the reorganization will total $2.3 million in 2008, slightly higher than the $2.0 million in annual savings originally anticipated.

          Net interest income was $32.4 million in the second quarter of 2007, a decrease of 2.4 percent from second quarter 2006 net interest income of $33.2 million. The decrease in net interest income was attributable primarily to the decrease in net interest margin. The net interest margin (on a tax-equivalent basis) in the second quarter of 2007 was 3.70 percent, down from 3.88 percent in the second quarter of 2006, but up slightly from 3.66 percent in the first quarter of 2007. The decline in net interest margin from the prior year was primarily attributable to increases in interest rates paid on interest-bearing liabilities exceeding increases in interest rates earned on interest-earning assets, as deposits repriced more rapidly than loans in the rising interest rate environment experienced in the past 12 months.

          Total assets were $3.78 billion at June 30, 2007, approximately the same as December 31, 2006, and up from $3.73 billion at June 30, 2006. At June 30, 2007, total loans were $2.80 billion, versus $2.81 billion at December 31, 2006 and $2.76 billion at June 30, 2006. The increase in loans since June 30, 2006 was attributable to the branch acquisitions completed in August 2006. Over the past twelve months, increases in residential real estate, commercial real estate and consumer loans have offset modest declines in commercial and real estate construction loans. Investment securities were $621 million at June 30, 2007, up slightly from $615 million at December 31, 2006 but down from $646 million at June 30, 2006. The decrease

2

in investment securities was primarily attributable to the Company using excess liquidity from maturing investment securities to fund higher yielding loan growth.

          Total deposits were $2.94 billion at June 30, 2007, up from $2.90 billion at December 31, 2006 and from $2.79 billion at June 30, 2006. Wholesale borrowings, primarily Federal Home Loan Bank advances, totaled $135 million at June 30, 2007, down $40 million, or 23 percent, from $175 million at December 31, 2006 and down $125 million, or 48 percent, from $260 million at June 30, 2006.

          The provision for loan losses was $2.50 million in the second quarter of 2007, compared to $1.63 million in the first quarter of 2007 and $0.40 million in the second quarter of 2006. Net loan charge-offs were $1.26 million in the second quarter of 2007, up from $0.71 million in the first quarter of 2007 and up from $0.92 million in the second quarter of 2006. The increases in the provision for loan losses in the second quarter of 2007, as compared to both the previous year's quarter and the first quarter of 2007, were reflective of the overall deterioration in credit quality during both periods. The allowance for loan losses of $36.25 million at June 30, 2007 was 1.30 percent of total loans, up from 1.25 percent of total loans at March 31, 2007 and 1.22 percent at June 30, 2006. At June 30, 2007, nonperforming loans as a percentage of total loans were 1.71 percent, up from 1.26 percent at March 31, 2007 and 0.99 percent at June 30, 2006.

          At June 30, 2007, nonperforming assets (nonperforming loans and repossessed assets) totaled $57.0 million, up from $44.4 million at March 31, 2007, and from $36.9 million at June 30, 2006. Nonperforming loans were $47.8 million at June 30, 2007, up from $35.2 million at March 31, 2007 and $26.9 million at December 31, 2006. The increases in nonperforming loans from both December 31, 2006 and March 31, 2007 to June 30, 2007 occurred primarily in the real estate commercial and real estate construction-commercial loan categories. Nonperforming real estate commercial and real estate construction-commercial loans were $30.1 million at June 30, 2007, up from $20.2 million at March 31, 2007 and $14.6 million at December 31, 2006. The increase in nonperforming real estate commercial and real estate construction-commercial loans during the second quarter of 2007 was primarily attributable to the addition of seven cus tomer relationships with borrowings between $0.5 million and $2.2 million and totaling $9.5 million.

3

          The allowance for loan losses as a percent of nonperforming loans has fallen from 100 percent at March 31, 2007 to 76 percent at June 30, 2007. The Company's $47.8 million of nonperforming loans at June 30, 2007 included commercial and real estate commercial loans totaling $22 million which have been individually analyzed and at that time deemed to have sufficient collateral values so as not to require an allocation of the allowance for loan losses to these loans.

          Total noninterest income was $11.36 million in the second quarter of 2007, up $0.84 million, or 8 percent, from $10.52 million in the second quarter of 2006. The increase was due to an increase in other noninterest income that was attributable to gains realized on the sale of a branch office building and the sale of a parcel of excess land contiguous to an existing branch office.

          Operating expenses in the second quarter of 2007 were $27.2 million, up from $25.1 million in the second quarter of 2006; due primarily to the reorganization costs incurred as a result of the Company's retail banking reorganization. Excluding these charges, operating expenses for the quarter would have increased by $0.5 million, or 2.0 percent. The Company's efficiency ratio was 61.4 percent in the second quarter of 2007, down from 63.2 percent in the first quarter of 2007 and up from 56.8 percent in the second quarter of 2006. The increase in the efficiency ratio from the prior year's quarter was attributable to both the decrease in net interest income and the increase in operating expenses, due largely to the $1.6 million of reorganization expenses.

          During the second quarter of 2007, the Company repurchased 449,800 shares of its common stock (on the open market) at an average price of $26.96 per share, bringing total share repurchases for the year 2007 to 472,800 shares. At June 30, 2007, the Company had 50,200 additional shares available for repurchases under the April 2007 authorization from its Board of Directors. On July 18, 2007, the Company announced that its Board of Directors authorized repurchases of up to 500,000 additional shares.

          The Company's return on average assets during the second quarter of 2007 was 1.00 percent, up from 0.97 percent in the first quarter of 2007 but down from 1.32 percent in the second quarter of 2006. The decline in return on assets resulted in a decline in return on average

4

equity to 7.5 percent in the second quarter of 2007 from 9.7 percent in the second quarter of 2006. At June 30, 2007, the Company's book value stood at $20.79 per share versus $20.32 per share at June 30, 2006.

          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 June 30, 2007, the Company had total assets of $3.78 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.
