<Page>1 Glen Ellyn, Illinois Contact: Scott W. Hamer January 28, 2010 President/CEO Company Release 630-545-0900 COMMUNITY FINANCIAL SHARES, INC. ANNOUNCES RESULTS FOR THE THREE MONTHS AND YEAR ENDED DECEMBER 31, 2009 Community Financial Shares, Inc. (OTCBB: CFIS) (the "Company"), the holding company for Community Bank-Wheaton/Glen Ellyn (the "Bank"), reported a net loss (unaudited) for the three months and year ended December 31, 2009 of $322,000 and $544,000, respectively. This compares to net losses of $234,000 and $1.3 million for the comparable prior year periods. Net loss available to common shareholders totaled $433,000 and $818,000 for the three months and year ended December 31, 2009, respectively. For the three months ended December 31, 2009, basic and diluted loss per share both totaled $0.35. This represents a decrease of 84.2% from $0.19 for both basic and diluted loss per share for the comparable prior year period. In addition, for the year ended December 31, 2009 basic and diluted loss per share both totaled $0.66. This represents an improvement of 35.9% from $1.03 for both basic and diluted loss per share for the year ended December 31, 2008. The increase in net loss for the three months ended December 31, 2009 is primarily the result of the net effect of a $509,000 increase in net interest income, a $74,000 increase in provision for loan losses, a $347,000 increase in noninterest expense, and a $66,000 increase in noninterest income. Similarly, the decrease in net loss for the year ended December 31, 2009 is primarily the result of the net effect of a $782,000 increase in net interest income, a $471,000 decrease in provision for loan losses, an $884,000 increase in noninterest income and a $940,000 increase in noninterest expense. Total assets at December 31, 2009 were $341.9 million, which represents an increase of $47.2 million, or 16.0%, compared to $294.7 million at December 31, 2008. The increase in total assets was the result of an increase in investment securities of $17.5 million, or 64.8%, to $44.5 million at December 31, 2009 from $27.0 million at December 31, 2008, an increase in loans receivable of $14.0 million, or 6.4%, to $233.6 million at December 31, 2009 from $219.6 million at December 31, 2008, and an increase in cash and cash equivalents of $10.0 million, or 63.3%, to $25.8 million at December 31, 2009 from $15.8 million at December 31, 2008. The growth in loans during the year ended December 31, 2009 was primarily due to continued strong lending and business <Page>2 relationships within our community maintained by our loan staff. The increase in investment securities was due to well priced opportunities in the market and the increase in cash and cash equivalents are due to the increase in deposits and a strategic decision to increase the Bank's liquidity position. Deposits increased $44.8 million, or 17.7%, to $298.3 million at December 31, 2009 from $253.5 million at December 31, 2008. This increase primarily consists of increases in the Bank's core deposit accounts, including: (1) an increase in interest bearing demand deposit accounts of $21.7 million, or 38.9%, to $77.5 million at December 31, 2009 from $55.8 million at December 31, 2008; (2) an increase in money market accounts of $4.1 million, or 10.6%, to $42.9 million at December 31, 2009 from $38.8 million at December 31, 2008; and (3) an increase in savings accounts of $3.1 million, or 13.4% to $26.1 million at December 31, 2009 from $23.0 million at December 31, 2008. The percentage of interest bearing deposit accounts to total deposits increased to 26.0% at December 31, 2009 from 22.0% at December 31, 2008 and the percentage of certificates of deposit to total deposits decreased to 40.8% at December 31, 2009 from 42.8% at December 31, 2008. Borrowed money, consisting of Federal Home Loan Bank advances and other borrowings, decreased $4.2 million, or 22.1%, to $14.8 million at December 31, 2009 from $19.0 million at December 31, 2008. Stockholders' equity increased $6.5 million, or 38.9%, to $23.1 million at December 31, 2009 from $16.6 million at December 31, 2008. The increase in stockholders' equity for the year ended December 31, 2009 was primarily the result of the receipt of a $6.97 million investment from the U.S. Department of the Treasury in May 2009 in exchange for 6,970 shares of the Company's preferred stock pursuant to the TARP Capital Purchase Program provided for under the Emergency Economic Stabilization Act of 2008 and an increase of $213,000 in the Company's accumulated other comprehensive income relating to the change in fair value of its available-for-sale investment portfolio. Partially offsetting these increases was the Company's net loss for the year ended December 31, 2009. As of December 31, 2009 there were 1,245,267 shares of Company common stock outstanding, resulting in a tangible book value of $13.13 per share at that date. Net interest income before provision for loan losses increased $509,000, or 25.6%, to $2.5 million for the three months ended December 31, 2009 and increased $782,000, or 9.5%, to $9.1 million for the year ended December 31, 2009 as compared to the comparable prior year periods. These increases are <Page>3 primarily due to decreases in the average cost of interest bearing liabilities of 84 and 88 basis points for the three months and year ended December 31, 2009, respectively. The average cost of interest bearing liabilities decreased to 1.67% and 1.94% for the three months and year ended December 31, 2009, respectively, from 2.51% and 2.82% for the comparable prior year periods. The effect of this decrease was partially offset by decreases in the average yield on interest-earning assets of 59 and 82 basis points for the three months and year ended December 31, 2009, respectively. The average yield on interest-earning assets decreased to 4.81% and 4.92% for the three months and year ended December 31, 2009, respectively, from 5.40% and 5.74% for the comparable prior year periods. The net interest margin, expressed as a percentage of average earning assets, increased 22 basis points to 3.27% for the three months ended December 31, 2009 from 3.05% for the three months ended December 31, 2008; however it remained unchanged at 3.13% for the year ended December 31, 2009 as compared to the prior year period. The average yield on loans decreased 27 and 53 basis points for the three months and year ended December 31, 2009, respectively, compared to the comparable prior year periods. This decrease is partially due to the fact that approximately one half of the Bank's loan portfolio consists of adjustable rate loans. The average yield on loans decreased to 5.39% and 5.49% for the three months and year ended December 31, 2009, respectively, from 5.66% and 6.02% for the comparable prior year periods. The provision for loan losses increased $74,000 for the three months ended December 31, 2009 and decreased $471,000 for the year ended December 31, 2009, compared to the prior year periods. The changes in the provision are the result of management's quarterly analysis of the allowance for loan loss. Nonperforming loans totaled $15.0 million, or 4.4% of total assets, at December 31, 2009 and $2.8 million, or 0.94% of total assets, at December 31, 2008. The ratio of the allowance for loan losses to nonperforming loans totaled 28.0% and 119.7% at December 31, 2009 and December 31, 2008, respectively. Management continues to take aggressive actions in dealing with problem credits. Noninterest income increased $66,000 to $470,000 for the three months ended December 31, 2009 as compared to the comparable prior year period. The increase is primarily due to an increase in gain on sale of loans of $122,000, which was partially offset by a decrease of $47,000 in service charges on deposit accounts and a loss on sale of foreclosed real estate of $18,000. <Page>4 Noninterest income increased $884,000, or 65.1%, to $2.2 million for the year ended December 31, 2009 as compared to the comparable prior year period. This increase is primarily due to increases in gain on sale of loans of $493,000 and a $485,000 loss on impairment related to FHLMC preferred stock incurred during the year ended December 31, 2008. The increase in gain on sale of loans is primarily due to a reduction in mortgage interest rates. Partially offsetting these increases are decreases in gains on sale of securities and service charges on deposit accounts of $29,000 and $84,000, respectively and an increase in loss on sale of foreclosed assets of $62,000. Noninterest expense increased $347,000, or 13.3%, to $2.9 million for the three months ended December 31, 2009 as compared to the comparable prior year period. This increase is primarily due to increases in compensation and benefits expense of $67,000 and FDIC premiums of $252,000. The increase in compensation and benefits expense is primarily the result of annual merit increases. These increases were partially offset by a $14,000 decrease in advertising and marketing expenses, a $15,000 decrease in data processing expenses and a $40,000 decrease in building and equipment expense, which is primarily the result of a successful petition to lower the real estate tax assessments on two Bank properties. Noninterest expenses increased $940,000, or 9.5%, to $10.9 million for the year ended December 31, 2009 as compared to the comparable prior year period. This increase is primarily due to higher FDIC premiums of $436,000 and special assessments of $148,000, and increased compensation and benefits expense of $237,000 and data processing expense of $33,000. Partially offsetting these increases was a decrease in advertising and marketing expense of $58,000.
