          FIRST MIDWEST FINANCIAL, INC. REPORTS THIRD QUARTER EARNINGS


(Storm Lake, Iowa - July 18, 2003) First Midwest reports net income of $892,000,
or $.36 per diluted  share,  for the third  quarter  ended June 30,  2003.  This
reflects a 68.9 percent increase  compared to the same period last year when net
income was  $528,000  or $.21 per diluted  share.  Net income for the first nine
months of the 2003 fiscal year  totaled  $2,652,000  or $1.06 per diluted  share
compared to  $1,413,000  or $.57 per diluted  share  during the same period last
year.

Net interest income for the first nine months of the 2003 fiscal year increased
$2,126,000, or 21.5 percent, compared to the same period last year. The increase
reflects the Company's 33 percent growth in checking and money market accounts
during the current fiscal year and a higher percentage of originated commercial
loans. During the first nine months of the 2003 fiscal year, total deposit
balances grew $77.1 million to $432.9 million.

The Company opened its fourth Des Moines bank in November 2002. In addition, the
Company is expanding and centralizing its mortgage loan operations. Startup
costs associated with this expansion and the new Des Moines office contributed
to an increase in noninterest expense for the first nine months of the current
fiscal year compared to the same period last year.

Shareholders of record on June 13, 2003, received a quarterly cash dividend of
13 cents per share. This dividend was paid on July 1, 2003. The company has paid
regular quarterly cash dividends since the first dividend paid on January 5,
1995.




At June 30, 2003, assets of First Midwest totaled $775 million, up 27.5 percent
or $167 million from 2002 fiscal year end. Shareholders' equity totaled $44.5
million, or $17.83 per common share outstanding. First Midwest is the holding
company for First Federal Savings Bank of the Midwest and Security State Bank.
All three companies had capital ratios well in excess of regulatory requirements
at June 30, 2003.

During this quarter, First Midwest shares traded between $16.21 and $19.25. The
stock of First Midwest Financial, Inc. trades on the Nasdaq National Market
under the symbol "CASH".
