Exhibit 99.1 NEWS RELEASE Date: July 20, 2005 11:30 a.m. E.S.T. Contact: James L. Saner, Sr., President and CEO MainSource Financial Group, Inc. 812-663-0157 [MainSource Financial Group logo] MAINSOURCE FINANCIAL GROUP - NASDAQ, MSFG - Announces Earnings for the Second Quarter 2005 + Net Income of $4.3 million + Return on Average Equity of 13.66% + Return on Average Assets of 1.15% + Net Interest Margin of 4.04% James L. Saner, Sr., President & CEO of MainSource Financial Group, Inc. (NASDAQ: MSFG), announced today the unaudited results for the second quarter ended June 30, 2005. Total net income for the second quarter was $4,326,000 compared to $4,319,000 for the same period in 2004. The Company reported earnings per share of $0.37, which represents a 2.6% decrease compared to the $0.38 per share reported in the second quarter of 2004. In June 2005, the Company completed a public offering of approximately 1.7 million shares of common stock. As previously announced, the majority of the proceeds from this offering will be used in the acquisition of The Madison Bank and Trust Company, which is expected to close in the third quarter of 2005. Excluding the effect of the additional shares issued in the offering, the Company's earnings per share would have been $0.38. For the six months ended June 30, 2005, the Company reported earnings per share of $0.70, which represents a 1.4% decrease over the $0.71 reported for the same period a year ago. Key measures of the financial performance of the Company are return on average shareholders' equity and return on average assets. Return on average shareholders' equity was 13.66% for the second quarter of 2005 and the return on average assets was 1.15% for the second quarter of 2005. For the six months ended June 30, 2005, the Company's return on average shareholders' equity was 12.96% and the return on average assets was 1.08%. Mr. Saner stated, "We are pleased with our performance in the second quarter given the fact that we will not be able to fully utilize the proceeds from our recent stock offering until the third quarter. Although our numbers are down slightly from the second quarter of 2004, we showed a significant improvement over the first quarter of this year. On a linked quarter basis, earnings per share, return on average assets, return on average equity, and net interest margin all increased substantially." NET INTEREST INCOME Net interest income was $13.2 million for the second quarter of 2005, which represents an increase of 7.3% versus the second quarter of 2004. Average earning assets increased 4.6% while net interest margin, on a fully-taxable equivalent basis, was 4.04% for the second quarter of 2005 compared to 3.85% for the same period a year ago. For the six months ended June 30, 2005, the Company's net interest margin was 3.95% versus 3.79% a year ago. NON-INTEREST INCOME Non-interest income was $4.8 million for the second quarter of 2005 compared to $5.3 million for the same period a year ago. This decrease was primarily due to a decrease in mortgage banking income and lower gains on sales of investment securities. In addition, insurance commission income decreased as the Company disposed of the Kentucky division of its insurance subsidiary in March 2005. The Company's Indiana insurance division realized an increase in commission income of 9% compared to the same period a year ago. NON-INTEREST EXPENSE Non-interest expense for the second quarter of 2005 was $11.9 million and was relatively flat compared to $11.7 million for the second quarter of 2004. The Company was able to keep expenses flat year over year despite the full quarter effect of Peoples Trust Company in 2005, which was acquired in mid-June 2004. The Company is beginning to realize the cost savings anticipated with the consolidation of its Indiana bank charters. ASSET QUALITY As expected, the Company's asset quality improved during the second quarter of 2005. Non-performing assets totaled $14.3 million, or 0.93% of total assets, as of June 30, 2005. The Company had $17.6 million of non-performing assets, or 1.18% of total assets as of March 31, 2005, and $15.7 million, or 1.02% of total assets at year-end 2004. The allowance for loan losses was $11.3 million as of June 30, 2005 which represented 1.23% of total outstanding loans. Mr. Saner stated, "Our efforts to reduce our non-performing assets have been successful over the last quarter as we continue to improve the asset quality of the Company. This continues to be a major focus for our Company in 2005."
