Exhibit 99.1 NEWS RELEASE DATE: April 13, 2005 12:00 p.m. E.S.T. CONTACT: James L. Saner, Sr., President and CEO 812-663-0157 [MainSource Logo] MAINSOURCE FINANCIAL GROUP-NASDAQ, MSFG - Announces Earnings for the First Quarter 2005 o Net Income of $3.8 million o Earnings Per Share of $0.33 o Net Interest Margin of 3.90% James L. Saner, Sr., President & CEO of MainSource Financial Group, Inc. (NASDAQ: MSFG), announced today the unaudited results for the first quarter ended March 31, 2005. Total net income for the first quarter was $3,790,000 compared to $3,635,000 for the same period in 2004. The Company reported earnings per share of $0.33, which was equal to the first quarter of 2004. The Company did, however, incur $140,000 of pre-tax expenses related to the continued collapsing of its Indiana bank charters into MainSource Bank which was announced in September 2004. Therefore, the Company's operating earnings per share were $0.34. 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 12.38% and return on average assets was 1.02% for the first quarter of 2005. Mr. Saner stated, "MainSource Financial Group continues to place its focus on building financial relationships with its customers while simultaneously looking for opportunities to enhance shareholder value. As interest rates continue to rise, our Company has attempted to stay competitive in its markets by raising its rates on loan and deposit products. As a result, our net interest margin continues to increase. However, mortgage banking income, which is a main driver of non-interest income, has decreased significantly. We do feel that the economy is recovering and therefore we anticipate commercial loan growth will increase in the future." NET INTEREST INCOME Net interest income was $12.7 million for the first quarter of 2005, which represents an increase of 10.7% versus the first quarter of 2004. Average earning assets increased 6.3% while net interest margin, on a fully-taxable equivalent basis, was 3.90% for the first quarter of 2005 compared to 3.68% for the same period a year ago and 3.76% for the fourth quarter of 2004. NON-INTEREST INCOME Non-interest income was $4.6 million for the first quarter of 2005 compared to $4.8 million for the same period a year ago. The decrease was primarily attributable to a decrease in mortgage banking income of $0.3 million, a lower level of securities gains, and a decrease in insurance commissions. Insurance commissions decreased as the Company sold the Kentucky division of MainSource Insurance during the quarter. Offsetting these decreases was an increase in service charges on deposit accounts and increases resulting from the acquisition of Peoples Trust in June 2004. NON-INTEREST EXPENSE Non-interest expense for the first quarter of 2005 was $12.1 million compared to $11.1 million for the first quarter of 2004. The increase was due primarily to the acquisition of Peoples Trust, which added approximately $0.9 million in non-interest expense. Excluding the effect of Peoples Trust, the Company's non-interest expense would have been approximately $11.2 million and relatively flat compared to the same period in 2004. ASSET QUALITY The Company's asset quality held steady as compared to the same period a year ago. Non-performing assets totaled $16.6 million, or 1.11% of total assets, as of March 31, 2005. This is compared to $16.6 million, or 1.13% of total assets, as of the same period a year ago. The allowance for loan losses was $11.5 million as of March 31, 2005 and represented 1.28% of total outstanding loans. Included in the $16.6 million of non-performing assets as of March 31, 2005, is one credit relationship in the approximate aggregate amount of $1.9 million. However, on April 8, 2005, the customer brought all of its loans to a current status. This customer has indicated that it intends to pay off at least half of the credit in the second quarter of 2005. Excluding this relationship, non-performing assets would have been $14.7 million, or 0.98% of total assets as of March 31, 2005.
