Exhibit 99.1 For: Immediate Release Contact: Larry Lentych July 27, 2006 574 235 2000 Andrea Short 574 235 2000 1ST SOURCE CORPORATION EARNINGS INCREASE IN 2ND QUARTER, STOCK AND CASH DIVIDENDS ANNOUNCED South Bend, IN -- 1st Source Corporation (Nasdaq:SRCE), parent company of 1st Source Bank, today reported net income of $10.28 million for the second quarter of 2006, an increase of 24.92 percent compared to the $8.23 million reported in the second quarter of 2005. For the first six months of 2006, net income for 1st Source Corporation was $20.21 million, a 33.21 percent increase over the $15.17 million reported for the same period in 2005. Diluted net income per common share for the second quarter of 2006 amounted to $0.45, up 25.00 percent compared with $0.36 reported in the second quarter of 2005. Diluted net income per share for the first two quarters of 2006 was $0.88, an increase of 33.33 percent over the $0.66 reported in the same period a year ago. (All share and per share information has been adjusted for a 10% stock dividend declared on July 27, 2006, unless otherwise noted.) Christopher J. Murphy III, Chairman and Chief Executive Officer, reported that at the July meeting, the Board of Directors approved a ten percent (10%) stock dividend of 1st Source common stock. The stock dividend will be payable to shareholders of record on August 7, 2006. The Board also approved a cash dividend increase to $0.14 per share, up 28.44 percent over the second quarter cash dividend in 2005. The cash dividend will be payable to shareholders of record on August 8, 2006. Both the stock dividend and cash dividend will be paid on August 15, 2006. Mr. Murphy commented, "It's been an especially good second quarter for 1st Source. Our loans grew steadily, and deposits were up. Credit quality remains very strong with net recoveries received during the quarter. Our net interest margin is slowly beginning to improve, but still remains pressured in 1 this challenging interest rate environment, and expenses are being tightly controlled. We continue to execute on our long range plans including the investment in new systems and facilities. The discipline and attention to detail are beginning to pay off." Mr. Murphy continued, "We were pleased that our 1st Source Corporation stock (SRCE) has been included in the NASDAQ Global Select Market. The new NASDAQ classification has the highest initial listing standards of any exchange in the world based on financial and liquidity requirements. We are honored to be listed among such a strong group of growing companies." 1st Source's reserve for loan and lease losses as of June 30, 2006, was 2.26 percent of total loans and leases compared to 2.50 percent at June 30, 2005. Net recoveries of $1.77 million were recorded for the second quarter 2006, compared to net recoveries of $0.31 million for the same quarter a year ago. Year-to-date net recoveries of $2.47 million have been recorded in 2006, compared to net charge-offs of $0.29 million for the first half of 2005. The ratio of nonperforming assets to net loans and leases was 0.57 percent on June 30, 2006, compared to 0.91 percent on June 30, 2005. Improvement in the net interest margin was reflective of the growth in loans and leases and yields on the loan and lease portfolios. The net interest margin was 3.44 percent for the second quarter of 2006 versus 3.18 percent for the same period in 2005. The net interest margin was 3.36 percent for the six months ending June 30, 2006, versus 3.16 percent for the same period in 2005. Tax-equivalent net interest income was $27.81 million for the second quarter of 2006, up 11.76 percent from 2005's second quarter. For the first six months of 2006, tax-equivalent interest income was $53.53 million compared to $49.14 million for the first six months of 2005, an increase of 8.94 percent. Noninterest income for the second quarter 2006 was $19.07 million, up 23.83 percent from the second quarter of 2005. For the first six months of 2006, noninterest income was $38.07 million up 15.05 percent from 2005. During the second quarter of 2006, mortgage banking income increased primarily due to a gain of $1.25 million on sale of mortgage servicing rights. Equipment rental income increased during the second quarter of 2006 mainly due to an increase in the operating lease portfolio and rental recoveries. Service charges on deposit accounts increased as a result of growth in the number of retail deposit accounts and increased overdraft and NSF fees. 2 Trust fees and insurance commissions increased in both the three and six month periods ended June 30, 2006, over the same periods in 2005. Trust fees increased due to growth in assets under management and an increase in IRA custodian revenue. Insurance commissions increased due to growth in commercial lines and higher premiums. Gains on venture partnership investments due to market value adjustments were significantly higher as compared to the first six months of 2005. Noninterest expense was $32.39 million for the second quarter of 2006, compared with $30.63 million for the second quarter of 2005. For the first six months, noninterest expense was $61.79 million, compared with $62.30 million for the same period in 2005. The overall decrease in noninterest expense was mainly reflected in salaries and employee benefits on a year-over-year basis which was primarily due to a one-time reduction in the accrual for stock-based compensation expense taken in the first quarter of 2006 related to the adoption of a new accounting standard. As of June 30, 2006, leased equipment depreciation increased on a year-over-year basis, primarily due to the increase in the operating lease portfolio. Professional fees increased mostly due to higher audit and regulatory examination fees. Other expenses were higher at June 30, 2006, as compared to one year ago as a result of higher legal contingency expenses and losses related to an employee defalcation. Furniture and equipment expense increased on a year-over-year basis due to increased software costs, expenses related to the core system conversion project and other processing charges. Supplies and communication and business development and marketing expense remained comparable to 2005 levels. As of June 30, 2006, the 1st Source common equity-to-assets ratio was 9.76 percent compared to 9.67 percent a year ago. Common shareholders' equity was $352.31 million, up 5.60 percent from the $333.61 million a year ago. Total assets at the end of the second quarter of 2006 were $3.61 billion, up 4.56 percent from the same time last year. Total deposits were up 2.82 percent and total loans and leases grew 9.85 percent over the comparable figures at the end of the second quarter of 2005. 1st Source is the largest locally controlled financial institution headquartered and serving the northern Indiana-southwestern Michigan area.
