Chemical Financial Corporation Reports Second Quarter 2006 Earnings

          Midland, MI, July 24, 2006--- Chemical Financial Corporation's (NASDAQ: CHFC) Board of Directors today announced 2006 second quarter net income of $12.2 million, or $0.49 per diluted share, versus reported net income of $13.2 million, or $0.53 per diluted share, in the second quarter of 2005.

          Net income was $24.1 million, or $0.96 per diluted share, in the first six months of 2006, compared to net income of $26.7 million, or $1.06 per diluted share, in the first six months of 2005.

          "Rising interest rates continued to negatively impact financial results during the second quarter. Increases in noninterest income were offset by a decrease in net interest income, due primarily to higher interest paid on deposits and short-term borrowings," said David B. Ramaker, Chairman, President and Chief Executive Officer of Chemical Financial Corporation.

          "The implementation phase of our previously announced strategic restructuring plan, which we believe will position the Company to better capitalize on growth opportunities and enhance operating efficiencies, is nearing completion. During the quarter, we announced the acquisition of two branch offices in the Grand Rapids market, which is expected to be completed in the third quarter. In addition, to bolster organic growth, we initiated a system-wide sales and service training program to improve sales, cross sales and customer development and retention across our 123 branch office

1

network. We continue to explore other avenues to enhance financial performance. Absent further interest rate increases, we are cautiously optimistic about the short-term financial outlook for the remainder of the year," added Ramaker.

          During the second quarter of 2006, restructuring costs of $0.17 million were incurred. Management had estimated that total costs for the restructuring would not exceed $0.8 million in 2006 and would be incurred primarily during the first half of the year. Actual restructuring costs incurred in the first six months of 2006 were $0.56 million. Management anticipates incurring the remaining $0.24 million of restructuring costs during the third quarter of 2006.

          Net interest income was $33.2 million in the second quarter of 2006, a decrease of 7.0 percent from second quarter 2005 net interest income of $35.7 million. The decrease in net interest income was attributable to decreases in both average interest-earning assets and the net interest margin, partially offset by a decrease in average interest-bearing liabilities. The net interest margin (on a tax-equivalent basis) fell from 4.10% in the second quarter of 2005 to 3.88% in the second quarter of 2006. The decline in net interest margin was primarily attributable to increases in rates paid on interest-bearing liabilities outstripping yields earned on interest-earning assets, as deposits continued to reprice more rapidly than loans in the rising interest rate environment.

          Total assets were $3.73 billion at June 30, 2006, down slightly from $3.75 billion at December 31, 2005 and up slightly from $3.72 billion at June 30, 2005. At June 30, 2006, total loans were $2.76 billion, versus $2.71 billion at December 31, 2005 and $2.65 billion at June 30, 2005. Investment securities were $646 million at June 30, 2006, down from $722 million at December 31, 2005 and $799 million at June 30, 2005. The decrease in investment securities was primarily attributable to the Company using excess liquidity from maturing investment securities to fund loan growth.

          Total deposits were $2.79 billion at June 30, 2006, down slightly from $2.82 billion at December 31, 2005 and from $2.82 billion at June 30, 2005. In the second

2

quarter of 2006, the Company continued to experience strong competition for deposits in the markets it serves. Other liabilities, which include Federal Home Loan Bank advances, totaled $440 million at June 30, 2006, up from $428 million at December 31, 2005 and from $403 million at June 30, 2005.

          The provision for loan losses was $400,000 in the second quarter of 2006, compared to $460,000 in the first quarter of 2006 and $730,000 in the second quarter of 2005. Net loan losses were $916,000 in the second quarter of 2006, compared to $454,000 in the first quarter of 2006 and $1,079,000 in the second quarter of 2005. Net loan losses in the second quarter of 2006 include a $0.6 million loss on a real estate commercial construction loan. The loan was deemed an impaired loan during the fourth quarter of 2005, with a $0.6 million impairment reserve. The remaining loan balance of $2.6 million was transferred to other real estate during the second quarter of 2006. The allowance for loan losses as a percentage of total loans was 1.22 percent at June 30, 2006, down from 1.27 percent at March 31, 2006 and from 1.27 percent at June 30, 2005. At June 30, 2006, nonperforming loans as a percentage of total loans were 0.99 percent, up from 0.73 percent at March 31, 2006 and up f rom 0.61 percent at June 30, 2005.

          On June 30, 2006, nonperforming assets totaled $36.9 million, up from $21.9 million at June 30, 2005 and $27.6 million at March 31, 2006. The increase in nonperforming assets from the previous quarter's end is due primarily to a $4.3 million increase in nonaccrual commercial loans and a $3.7 million increase in real estate commercial loans past due 90 days or more. While nonperforming assets have increased, management does not anticipate increased significant loss exposure as a result of this increase.

          Total noninterest income was $10.5 million in the second quarter of 2006, up $0.8 million, or 7.8 percent, from the second quarter of 2005. In the second quarter of 2006, the Company experienced increases in service charges on deposit accounts, as well as increases in other fees for customer services, compared to the second quarter of 2005.

          Operating expenses were $25.1 million in the second quarter of 2006, up $0.3 million, or 1.3 percent, from the second quarter of 2005, and unchanged from $25.1 million in the first quarter of 2006. Excluding restructuring expenses of $0.17 million incurred in the second quarter of 2006 in conjunction with the strategic restructuring, operating expenses in the second quarter of 2006 were $24.9 million. The Company's efficiency ratio was 56.8 percent in the second quarter of 2006, down from 57.3 percent in the first quarter of 2006, although up from 54.0 percent in the second quarter of 2005. The increase in the ratio from the prior year is primarily attributable to the decrease in net interest income.

          The Company's return on average assets during the second quarter of 2006 was 1.32 percent, down from 1.41 percent in the second quarter of 2005 and up slightly from 1.28 percent in the first quarter of 2006. Shareholders' equity increased from $495 million at June 30, 2005 to $500 million at June 30, 2006. At June 30, 2006, the Company's book value stood at $20.14 per share versus $19.68 per share at June 30, 2005. The decline in return on assets combined with the increase in shareholders' equity resulted in a decline in return on average equity to 9.7 percent in the second quarter of 2006 from 10.8 percent in the second quarter of 2005.

          Chemical Financial Corporation is the fourth largest bank holding company headquartered in Michigan. The Company operates through a single subsidiary bank, Chemical Bank, with 123 banking offices spread over 32 counties in the lower peninsula of Michigan. At June 30, 2006, the Company had total assets of $3.73 billion.
