Greensburg, Indiana, Archie M. Brown, Jr., President and Chief Executive Officer of MainSource Financial Group, Inc. (NASDAQ: MSFG) announced today the unaudited financial results for the quarter and year ended December 31, 2013.  For the three months ended December 31, 2013, the Company recorded net income of $7.4 million, or $0.36 per common share, compared to net income of $7.3 million, or $0.34 per common share, in the fourth quarter of 2012.  The primary reason for the increase in earnings per share was the payoff of the remaining shares of the Series A preferred stock in the 3Q of 2013 and the resulting savings of the preferred stock dividend.  In addition, reductions in provision expense and OREO losses were offset by increases in employee and equipment expenses and a reduction in mortgage banking income.

For the twelve months ended December 31, 2013, the Company reported net income of $26.3 million, or $1.26 per common share, compared to net income in 2012 of $27.3 million, or $1.30 per common share.  Similar to the fourth quarter results, the primary drivers of the change in net income in 2013 compared to 2012 were an increase in trust and investment product fees and a decrease in loan loss provision expense, offset by decreases in mortgage banking income and increases in employee and equipment costs.

The Company also announced that the Board of Directors declared a first quarter common dividend of $0.10 per share at its January 21, 2014 meeting.  This represents an increase of $.02 per share from the dividend paid during the previous quarter.  The dividend is payable on March 14, 2014 to common shareholders of record as of March 4, 2014.

Mr. Brown commented on the fourth quarter, “I am pleased with our recent performance.  Our earnings of $7.4 million were in line with our expectations, credit quality continued to improve to levels that existed prior to the recession and our $61 million in loan growth, which represents an annualized rate of 15% growth, was the highest level of the year. “

Mr. Brown continued, “During the quarter we made additional investments in lending personnel including adding a sales representative and manager to Equipment Finance and adding a commercial banking team in Louisville.  We anticipate production from these new teams ramping up during the first part of 2014 and for full production to occur by mid-year.  These new teams are part of our strategy to grow organically.  In addition to the new teams we added in the fourth quarter, in the last 18 months, we have added teams in Indianapolis, Seymour, and Bloomington, Indiana as well as Cincinnati, Ohio.  Our fourth quarter loan growth reflects some of the early success we have realized from these recent investments.”

4TH QUARTER RESULTS

NET INTEREST INCOME

Net interest income was $23.2 million for the fourth quarter of 2013.  Net interest margin, on a fully-taxable equivalent basis, was 3.88% for the fourth quarter of 2013 which was fifteen basis points below the fourth quarter of 2012 and three basis points lower than the third quarter of 2013.  The Company’s net interest margin decreased from a year ago due to the repricing of the asset side of the balance sheet.  While deposit and other funding costs have decreased over the same period, many of these accounts have reached, or are approaching, their floors.  Linked quarter net interest income increased slightly as the level of earning assets increased in the fourth quarter due to the $61 million of loan growth during the quarter, which represents 15% growth in loans on an annualized basis.

NON-INTEREST INCOME

The Company’s non-interest income was $10.3 million for the fourth quarter of 2013 compared to $11.7 million in the same period in 2012.  Mortgage banking income, which was $3.6 million for the fourth quarter of 2012, decreased by $2.3 million from the same period a year ago as refinance activity slowed due to the increase in interest rates.  Other non-interest income increased from a year ago as OREO activity decreased in the fourth quarter of 2013 compared to 2012 and resulted in a reduced amount of losses on sale.

NON-INTEREST EXPENSE

The Company’s non-interest expense was $23.8 million for the fourth quarter of 2013 compared to $23.7 million for the same period in 2012.  An increase in employee and equipment costs related to investments in new markets was offset by decreases in marketing expenses and “other” expenses (primarily professional fees and certain state taxes).

FULL YEAR RESULTS

Mr. Brown commented on the company’s full year results, “I am very pleased with our results for 2013.  Our net income and earnings per share when adjusting for non-operating items were $27.7 million and $1.33 respectively, our highest since the recession and second highest in company history.  Credit quality as measured by non-performing assets to total assets declined to 1.07%, the lowest level in over five years and loans grew by more than 7% with momentum in loan growth increasing as we ended the year.  In addition, we redeemed the remaining preferred shares outstanding from the former TARP program; we increased our quarterly dividend from $.03 per share to $.08 per share by the fourth quarter and our stock price increased by 42%.  We have recovered very well from the effects of the recession and have positioned the company for future growth.”

NET INTEREST INCOME

Net interest income was $91.3 million for the full year 2013, which represents a decrease of $2.8 million when compared to the twelve months ended December 31, 2012.  Net interest margin, on a fully-taxable equivalent basis, decreased from 4.08% in 2012 to 3.92% in 2013.  As rates have remained at historic lows for an extended period of time, the Company’s asset base has continued to reprice lower.  The Company’s cost of funds also decreased over the same period but to a lesser extent.  Partially offsetting the decrease in the Company’s net interest margin, average earning assets increased by approximately $27 million in 2013 compared to 2012 as the Company experienced increased loan demand in 2013.

NON-INTEREST INCOME

The Company’s non-interest income was $43.1 million for the full year 2013 compared to $43.9 million for 2012.  Excluding securities gains, non-interest income was $42.3 million in 2013 compared to $42.5 million in 2012.  The primary drivers of the slight decrease were a decrease in mortgage banking income of $3.1 million offset by an increase in trust and investment product fees of $1.1 million.  In addition, service charges on deposit accounts and interchange income increased by $1.1 million collectively and losses on OREO sales were $0.8 million lower year over year.

NON-INTEREST EXPENSE

The Company’s non-interest expense was $98.2 million for the full year 2013 compared to $94.8 million for 2012.  During 2013, the Company incurred a non-operating expense of $2.2 million related to the prepayment of an FHLB advance.  During 2012, the Company incurred the following non-operating expenses: a $1.3 million charge related to the prepayment of an FHLB advance, $0.7 million of costs related to the closure of six branches, and $0.3 million of costs related to the U.S. Treasury’s auction of the Company’s Series A preferred stock.  Excluding these items, the Company’s non-interest expense would have been $96.0 million in 2013 and $92.5 million in 2012.  The increase of $3.5 million was primarily attributable to the increase in employee costs of $3.2 million which was a result of the Company’s investments in new markets.

ASSET QUALITY

Non-performing assets (NPA’s) were $30.7 million as of December 31, 2013, a decrease of $27.1 million from year-end 2012 and $6.3 million on a linked-quarter basis.  NPA’s represented 1.07% of total assets as of December 31, 2013 compared to 1.31% as of September 30, 2013 and 2.09% as of December 31, 2012.  Net charge-offs were $1.0 million for the fourth quarter of 2013 and represented 0.25% of average loans on an annualized basis.  Total loan loss provision expense was $0.8 million in the fourth quarter of 2013 compared to $2.3 million in the fourth quarter of 2012.  For the full year 2013, net charge-offs were $9.2 million or 0.57% of average loans.  The Company’s allowance for loan losses as a percent of total outstanding loans was 1.65% as of December 31, 2013 compared to 2.07% as of December 31, 2012.

Asset Quality

(1) Tangible common equity, tangible assets and tangible book value per share are non-GAAP financial measures calculated using GAAP amounts. Tangible common equity is calculated by excluding the balance of preferred stock, goodwill and other intangible assets from the calculation of stockholders’ equity. Tangible assets are calculated by excluding the balance of goodwill and other intangible assets from the calculation of total assets. Tangible book value per share is calculated by dividing tangible common equity by the number of shares outstanding. The Company believes that these non-GAAP financial measures provide information to investors that is useful in understanding its financial condition. Because not all companies use the same calculation of tangible common equity and tangible assets, this presentation may not be comparable to other similarly titled measures calculated by other companies. A reconciliation of these non-GAAP financial measures is provided below (dollars in thousands, except per share data).
