Exhibit 99.1 For: Immediate Release Contact: Larry Lentych April 27, 2006 574 235 2000 Andrea Short 574 235 2000 1ST SOURCE INCOME RISES IN FIRST QUARTER, CASH DIVIDEND REPORTED South Bend, IN -- 1st Source Corporation (Nasdaq: SRCE), parent company of 1st Source Bank, today reported net income of $9.93 million for the first quarter of 2006, up 43.04 percent over the $6.94 million reported in the first quarter of 2005. Christopher J. Murphy III, Chairman and Chief Executive Officer, commented on the first quarter by saying, "The performance of 1st Source continues to improve. It's been a busy and rewarding quarter. Assets, loans and leases, and deposits all grew. New banking centers were opened in Elkhart and Dowagiac, with the Dowagiac branch employing a new design. We were named as one of the "Best Places to Work in Indiana" in a survey sponsored by the Indiana Chamber and readers of our regional newspapers again selected us as the Best Bank in their readers' poll. Also, 1st Source has recently been selected as a founding member of the new NASDAQ Dividend Achievers Index, a special group of companies that have increased their annual regular dividend payments for the last 10 or more consecutive years." Mr. Murphy continued, "The quarter was also helped by one time events. We benefited by changes in compensation expenses of $1.5 million, and gains in venture capital investments of over $2.0 million. Credit quality was good as reflected by net recoveries for the period. Due to our concern about the increasing costs of oil and gas, and the problems being experienced by the U.S. auto industry and its effect on our regional economy and national niche businesses, we have continued to maintain strong credit reserves. Overall, it's a good, strong start to the year." 1 Diluted net income per share of common stock for the first quarter of 2006 amounted to $0.48 compared with $0.33 for the first quarter of 2005, an increase of 45.45 percent. Return on average common shareholders' equity for 1st Source Corporation was 11.53 percent compared to 8.60 percent for the first quarter of 2005, and return on average total assets was 1.18 percent compared to 0.84 percent a year ago. At its April meeting, the Board of Directors approved a first quarter cash dividend of $0.14 per common share, an increase of 16.67 percent over the first quarter cash dividend in 2005. The cash dividend will be payable on May 15, 2006, to shareholders of record May 8, 2006. As of March 31, 2006, the common equity-to-assets ratio for 1st Source was 10.04 percent, up from 9.78 percent a year ago. Common shareholders' equity was $347.35 million, up 6.34 percent from March 31, 2005. At the end of the first quarter of 2006, total assets were $3.46 billion, up 3.55 percent from a year ago. Loans and leases increased 8.80 percent and deposits increased 3.42 percent from a year ago. For the first quarter of 2006, 1st Source's recovery of provision for loan and lease losses was $0.30 million as compared to $0.42 million for the first quarter of 2005. Net recoveries were $0.70 million for the first quarter of 2006 compared to net charge-offs of $0.60 million in the first quarter of 2005. The reserve for loan and lease losses as of March 31, 2006, was 2.38 percent of total loans and leases compared to 2.75 percent as of March 31, 2005. The ratio of nonperforming assets to net loans and leases was 0.83 percent on March 31, 2006, compared to 1.10 percent for the same period last year. Tax-equivalent net interest income was $25.72 million for the first quarter of 2006, up 6.06 percent from 2005's first quarter, and the net interest margin was 3.29 percent versus 3.15 percent in the first quarter of 2005. Noninterest income for the three-month periods ended March 31, 2006 and 2005 was $19.01 million and $17.70 million, respectively. The predominant factor behind the increase in 2006 was gains on venture capital investments, due to market value adjustments. Insurance commissions, service charges on deposit accounts, equipment rental income, and trust fees increased during the first quarter of 2006 as compared to the first quarter 2005. These increases were partially offset by a decrease in mortgage banking income which was primarily due to minimal recoveries of mortgage servicing rights in the first quarter of 2006 compared to significant recoveries in the first quarter of 2005. 2 Noninterest expense for the three-month periods ended March 31, 2006 and 2005 was $29.41 million and $31.67 million, respectively. The decrease in noninterest expense for the first quarter of 2006 was primarily due to a one time reduction in the accrual for stock-based compensation expense related to the recognition of estimated forfeitures and the adoption of the new accounting standard on stock-based compensation. Additionally, group insurance costs were lower for the first quarter 2006 versus the first quarter of 2005. 1st Source is the largest locally controlled financial institution headquartered and serving the northern Indiana-southwestern Michigan area.
