                        COMMUNITY FINANCIAL SHARES, INC.
       ANNOUNCES RESULTS FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2009

      Community Financial Shares, Inc. (OTCBB: CFIS) (the "Company"), the
holding company for Community Bank-Wheaton/Glen Ellyn (the "Bank"), reported net
losses (unaudited) for the three and six months ended June 30, 2009 of $390,000
and $308,000, respectively. This compares to net losses of $327,000 and $246,000
for the comparable prior year periods. For the three months ended June 30, 2009,
basic and diluted loss per share both totaled $0.31. This represents a decrease
of 19.2% from $0.26 for both basic and diluted loss per share for the comparable
prior year period. In addition, for the six months ended June 30, 2009 basic and
diluted loss per share both totaled $0.25. This represents a decrease of 25.0%
from $0.20 for both basic and diluted loss per share for the six months ended
June 30, 2008. The increase in net loss for the three months ended June 30, 2009
is primarily the result of the net effect of a $70,000 increase in provision for
loan losses, a $337,000 increase in noninterest expense, a $68,000 increase in
net interest income and a $247,000 increase in noninterest income. Similarly,
the increase in net loss for the six months ended June 30, 2009 is primarily the
result of the net effect of a $130,000 increase in provision for loan losses, a
$60,000 increase in net interest income, a $247,000 increase in noninterest
income and a $270,000 increase in noninterest expense.

      Total assets at June 30, 2009 were $315.9 million, which represents an
increase of $21.2 million, or 7.2%, compared to $294.7 million at December 31,
2008. The increase in total assets was the result of an increase in investment
securities of $13.4 million, or 49.6%, to $40.3 million at June 30, 2009 from
$27.0 million at December 31, 2008, and an increase in loans receivable of $7.0
million, or 3.2%, to $226.6 million at June 30, 2009 from $219.6 million at
December 31, 2008. In addition, loans receivable increased $11.2 million, or
5.2%, from $215.5 million at March 31, 2009. Partially offsetting these
increases was a decrease in cash and cash equivalents of $1.6 million to $14.2
million at June 30, 2009 from $15.8 million at December 31, 2008. The growth in
loans during the six months ended June 30, 2009 is primarily due to continued
strong relationships within our community maintained by our loan staff. The
increase in investment securities was due to opportunities in the market.

Deposits increased $14.4 million, or 5.7%, to $268.0 million at June 30, 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 $11.1 million, or 19.8%, to $66.9
million at June 30, 2009 from $55.8 million at December 31, 2008; and (2) an
increase in money market accounts of $1.9 million, or 4.9%, to $40.7 million at
June 30, 2009 from $38.8 million at December 31, 2008. The percentage of
interest bearing deposit accounts to total deposits increased to 24.6% at June
30, 2009 from 22.0% at December 31, 2008 and the percentage of certificates of
deposit to total deposits decreased to 39.8% at June 30, 2009 from 42.8% at
December 31, 2008. Borrowed money, consisting of Federal Home Loan Bank advances
and other borrowings, remained unchanged at $19.0 million as of June 30, 2009
and December 31, 2008.

      Stockholders' equity increased $6.5 million, or 39.4%, to $23.2 million at
June 30, 2009 from $16.6 million at December 31, 2008. The increase in
stockholders' equity for the six months ended June 30, 2009 was primarily the
result of the receipt of a $6.97 million investment from the U.S. Department of
the Treasury 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. Partially offsetting this increase was a
decrease of $125,000 in the Company's accumulated other comprehensive income
relating to the change in fair value of its available-for-sale investment
portfolio and the Company's net loss for the six months ended June 30, 2009. As
of June 30, 2009 there were 1,245,267 shares of Company common stock
outstanding, resulting in a book value of $13.00 per share at that date.

      Net interest income before provision for loan losses increased $68,000, or
3.2%, to $2.2 million for the three months ended June 30, 2009 and $60,000, or
1.5%, to $4.2 million for the six months ended June 30, 2009 as compared to the
comparable prior year periods. These increases are primarily due to decreases in
the average cost of interest bearing liabilities of 78 and 97 basis points for
the three and six months ended June 30, 2009, respectively. The average cost of
interest bearing liabilities decreased to 2.05% and 2.14% for the three and six
months ended June 30, 2009, respectively, from 2.83% and 3.11% for the
comparable prior year periods. The effect of this decrease in average cost was
partially offset by decreases in the average yield on interest-earning assets of
79 and 92 basis points for the three and six months ended June 30, 2009,
respectively. The average yield on interest-earning assets decreased to 4.97%
and 5.03% for the three and six months ended June 30, 2009, respectively, from
5.76% and 5.95% for the comparable prior year periods. The net interest margin,

expressed as a percentage of average earning assets, decreased 10 basis points
to 3.06% for the three months ended June 30, 2009 from 3.16% for the three
months ended June 30, 2008; however it increased 6 basis points from the three
months ended March 31, 2009, and decreased 5 basis points to 3.03% for the six
months ended June 30, 2009 from 3.08% for the six months ended June 30, 2008.
The average yield on loans decreased 41 and 62 basis points for the three and
six months ended June 30, 2009, respectively, compared to the comparable prior
year periods. This decrease is partially due to approximately one-half of the
Bank's loan portfolio being adjustable rate. The average yield on loans
decreased to 5.64% and 5.63% for the three and six months ended June 30, 2009,
respectively, from 6.05% and 6.25% for the comparable prior year periods.

      The provision for loan losses increased $70,000 and $130,000 for the three
and six months ended June 30, 2009, respectively, compared to the prior year
period. The increase in the provision was the result of management's quarterly
analysis of the allowance for loan loss. Nonperforming loans totaled $4.6
million, or 1.46% of total assets, at June 30, 2009 and $3.1 million, or 1.09%
of total assets, at June 30, 2008. The ratio of the allowance for loan losses to
nonperforming loans totaled 86.6% and 89.2% at June 30, 2009 and June 30, 2008,
respectively.

      Noninterest income increased $247,000, or 54.4%, to $700,000 for the three
months ended June 30, 2009 as compared to the comparable prior year period. The
increase is primarily due to increases in gain on sale of loans of $193,000 and
fees generated by the Company's investment center of $14,000. Noninterest income
increased $247,000, or 25.1%, to $1.2 million for the six months ended June 30,
2009 as compared to the comparable prior year period. This increase is primarily
due to increases in gain on sale of loans of $254,000 and fees generated by the
Company's investment center of $18,000. Partially offsetting these increases are
a decrease in gains on sale of securities of $29,000 and an increase in loss on
sale of foreclosed assets of $54,000.

      Noninterest expense increased $337,000, or 14.0%, to $2.7 million for the
three months ended June 30, 2009 as compared to the comparable prior year
period. This increase is primarily due to an increase in FDIC premiums of
$79,000 and special assessments of $148,000, compensation and benefits expense
of $98,000, building and equipment expense of $18,000 and data processing
expense of $18,000. The increase in compensation and benefits expense is the

<Page>4

result of annual merit increases. The increase in building and equipment expense
are partially due to higher real estate taxes. These increases are partially
offset by lower advertising and marketing expenses of $25,000. Noninterest
expenses increased $270,000, or 5.5%, to $5.2 million for the six months ended
June 30, 2009 as compared to the comparable prior year period. This increase is
primarily due to increases in FDIC premiums and special assessments of $228,000,
compensation and benefits expense of $56,000, building and equipment expense of
$38,000, data processing expense of $29,000. Partially offsetting these
increases was a decrease in advertising and marketing expense of $29,000.
