1st Source Corp. Announces Increased 1st Quarter Earnings, Dividend
Reported

    SOUTH BEND, Ind.--(BUSINESS WIRE)--April 30, 2003--1st Source
Corporation (Nasdaq:SRCE), parent company of 1st Source Bank, today
reported net income of $4.46 million for the first quarter of 2003, up
5.99 percent compared to the $4.21 million in the first quarter of
2002.
    Diluted net income per share of common stock for the first quarter
of 2003 amounted to $0.21 compared with $0.20 for the first quarter of
2002, an increase of 5.0 percent. Return on average common
shareholders' equity for 1st Source Corporation was 5.80 percent
compared to 5.47 percent for the first quarter of 2002, and return on
average total assets was 0.55 percent compared to 0.49 percent a year
ago.
    At their April meeting, the Board of Directors approved a first
quarter cash dividend of $0.09 per common share. The cash dividend
will be payable on May 15, 2003, to shareholders of record May 5,
2003, and is equal to the first quarter cash dividend in 2002.
    Christopher J. Murphy III, Chairman and Chief Executive Officer,
commented on the first quarter by saying, "Our performance in the
first quarter of 2003 is a slight improvement over last year, and was
managed with no help from the stalled economy. We are pleased that our
credit situation has currently stabilized as our sale of repossessions
increased and our charge-offs decreased. We're hopeful that the
successful conclusion to the war will help stabilize fuel rates and
encourage business to begin investing in new plant and equipment.
Furthermore, fuel price stability should improve the business climate
for our niche areas which supply specialized financing services for
used private and cargo aircraft, automobiles for leasing and rental
agencies, heavy duty trucks, construction and environmental equipment
.... all of which are heavily dependent on gas prices."
    "I am most pleased with the strong showing of other areas of the
bank. Our retail branch network continues to increase the number of
customers we serve, as well as gain market share, and remains the
dominant retail financial institution in our area. We've attained
excellent growth in our investments under management, increased the
number of clients we serve in our trust department, and our insurance
and 401(k) management areas are turning in strong performances. All of
this is achieved by meeting the needs of our customers, one customer
at a time," Murphy concluded.
    As of March 31, 2003, the common equity-to-assets ratio for 1st
Source was 9.57 percent, up from 8.85 percent a year ago. Common
shareholders' equity was $313.54 million, up 1.78 percent from March
31, 2002. At the end of the first quarter of 2003, total assets were
$3.28 billion, down 5.92 percent from a year ago. Loans and deposits
were down 10.48 percent and 4.48 percent, respectively, from a year
ago.
    For the first quarter of 2003, 1st Source's provision for loan
losses was $5.55 million as compared to $11.81 million for the first
quarter of 2002. Net charge-offs were $2.92 million for the first
quarter of 2003 compared to $11.54 million in the first quarter of
2002. The resulting reserve for loan losses as of March 31, 2003 was
2.73 percent of total loans, compared to 2.29 percent as of March 31,
2002. The ratio of nonperforming assets to net loans and leases was
2.97 percent on March 31, 2003 compared to 2.01 percent for the same
period last year.
    Tax-equivalent net interest income was $27.31 million for the
first quarter, down 12.85 percent from 2002's first quarter, and the
net interest margin was 3.72 percent versus 4.00 percent in 2002. The
lower margin was due to reduced earning assets and reduced asset
yields, reflecting the effect of fewer loans in our specialty finance
group and lower market interest rates.
    Noninterest income for the first quarter 2003 was $20.04 million,
up 7.26 percent from the first quarter of 2002. Loan servicing and
sale income was up as increased mortgage revenue more than offset
decreased securitization income. Insurance commissions and trading
security income also increased in 2003.
    Noninterest expense was $34.8 million for the first quarter 2003,
up 7.93 percent from the first quarter of 2002, and down 10.67 percent
from the fourth quarter. These fluctuations are primarily due to the
timing of loan collection and repossession expense. As 1st Source
continues to work through problem loans and liquidate repossessions
primarily in its aircraft and auto financing businesses, expenses in
this area remain higher than one year ago.
    1st Source is the largest locally controlled financial institution
headquartered in the Northern Indiana-Southwestern Michigan area.
