EXHIBIT 99.1 NEWS RELEASE DATE: October 19, 2005 11:00 a.m. E.S.T. CONTACT: James L. Saner, Sr., President and CEO MainSource Financial Group, Inc. 812-663-0157 [MainSource logo] MAINSOURCE FINANCIAL GROUP-NASDAQ, MSFG - Announces Earnings for the Third Quarter 2005 o Net Income of $4.5 million o Return on Average Assets of 1.13% o Net Interest Margin of 3.93% James L. Saner, Sr., President & CEO of MainSource Financial Group, Inc. (NASDAQ: MSFG), announced today the unaudited results for the third quarter ended September 30, 2005. Total net income for the third quarter was $4,532,000 compared to $4,606,000 for the same period in 2004. The Company reported earnings per share of $0.34, which includes the effect of the Company's two million shares of common stock issued in a public offering in June and July of 2005. The Company was not able to fully utilize the new capital generated from the offering until the close of its acquisition of The Madison Bank and Trust Company, which occurred on August 26, 2005. Excluding the effect of the additional shares issued in the offering and the merger expenses related to the aforementioned acquisition, the Company's earnings per share would have been $0.38 for the third quarter of 2005 compared to $0.40 for the same period a year ago. For the nine months ended September 30, 2005, the Company reported earnings per share of $1.03, which represents a 7.2% decrease versus the $1.11 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 11.30% for the third quarter of 2005 and the return on average assets was 1.13% for the same period. For the nine months ended September 30, 2005, the Company's return on average shareholders' equity was 12.32% and the return on average assets was 1.10%. Mr. Saner stated, "We are pleased with our performance in the third quarter given the fact that we were not able to fully utilize the proceeds from our recent stock offering until the Madison Bank and Trust transaction closed in late August. Although our numbers are down slightly from last year through the first nine months, we showed a significant overall improvement during the last month of the quarter which included the first full month of the new acquisition." NET INTEREST INCOME Net interest income was $13.6 million for the third quarter of 2005, relatively flat compared to the third quarter of 2004. Average earning assets increased 2.7% while net interest margin, on a fully-taxable equivalent basis, was 3.93% for the third quarter of 2005 compared to 3.97% for the same period a year ago. For the nine months ended September 30, 2005, the Company's net interest margin was 3.93% versus 3.85% a year ago. NON-INTEREST INCOME Non-interest income was $4.9 million for the third quarter of 2005 and was relatively flat compared to the same period a year ago. An increase in mortgage banking income was offset by a decrease in insurance commission income as the Company disposed of the Kentucky division of its insurance subsidiary in March 2005. NON-INTEREST EXPENSE Non-interest expense for the third quarter of 2005 was $12.1 million, which was an increase of $0.3 million compared to the third quarter of 2004. The increase was primarily attributable to the merger costs associated with the acquisition of Madison, which totaled $0.3 million. Excluding these costs, the Company's non-interest expense would have been relatively flat. This expense control can be primarily attributed to the cost savings associated with the consolidation of the Company's Indiana bank charters. ASSET QUALITY The Company's asset quality remained relatively flat during the third quarter of 2005. Non-performing assets totaled $15.4 million, or 0.94% of total assets, as of September 30, 2005. The Company had $14.3 million of non-performing assets, or 0.93% of total assets as of June 30, 2005, and $17.6 million, or 1.18% of total assets at March 31, 2005. The allowance for loan losses was $12.5 million as of September 30, 2005 which represented 1.28% of total outstanding loans.
