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 fourth quarter of 2016.  For the three months ended December 31, 2016, the Company recorded net income of $11.7 million, or $0.48 per common share, compared to net income of $9.1 million, or $0.42 per common share, in the fourth quarter of 2015.  During the fourth quarter of 2016 the Company incurred costs of $166 thousand related to its May 2016 acquisition of Cheviot Financial Corp. and a charge of $650 thousand related to the closing of three branch offices.  Excluding these charges, the Company’s net income would have been $12.3 million or $0.50 per share (see Reconciliation of Actual to Operating Earnings included with this press release).   

CEO Comments

Mr. Brown commented on the Company’s fourth quarter performance, “I am very pleased with our fourth quarter and full year results.  On an operating basis we earned $1.86 per share for 2016 which represents a 9% increase over the prior year.  Our successful integration of the Cheviot acquisition and our organic loan growth were key factors to our strong performance.  We are especially pleased with our loan growth for the fourth quarter of 11% on an annualized basis.  Our strategy of growing into nearby metropolitan markets is paying off and we are optimistic about our ability to continue to grow loans at a moderate pace.”

Mr. Brown continued, “In December we announced our agreement to acquire FCB Bancorp, Inc., a $525 million bank holding company headquartered in Louisville, KY.  This acquisition strengthens our presence in the Louisville MSA by adding seven branch offices with approximately $400 million in deposits and positions us with a top ten market share.  We have begun the work with FCB employees to ensure a successful merger which we anticipate will occur in the second quarter of 2017.  We look forward to having the FCB employees join the MainSource team.”

Mr. Brown concluded, “In January our board declared a quarterly common dividend of $0.16 per share payable on March 15, 2017 to shareholders of record on March 6, 2017.  This represents a dividend yield of 2.0%.  On January 18, 2017, Charles J. Thayer, Lead Director, announced his upcoming retirement from the board in May 2017.  Charles has served on the board since 2011.  We are very appreciative of Charles’ contribution to the Company over the past six years.  In order to ensure a successful transition, the Board appointed Kathleen L. Bardwell as Lead Director effective with its January 2017 meeting.  Kathie has served on our board since 2011 and most recently chaired the Audit Committee.  We congratulate her on this appointment.”

NET INTEREST INCOME

Net interest income was $32.0 million for the fourth quarter of 2017 compared to $26.2 million a year ago.  The increase in net interest income was primarily due to an increase in average earning assets as well as an increase in purchase accounting adjustments.  Average earning assets increased year over year by $610 million with $430 million coming from the Cheviot acquisition and $180 million from organic growth.  Net interest margin, on a fully-taxable equivalent basis, was 3.69% for the fourth quarter of 2016, which was a one basis point increase from the fourth quarter of 2015 and an increase of seven basis points compared to the third quarter of 2016.  The increase in the net interest margin on a linked-quarter basis was primarily attributable to an increase in the accretion of purchase accounting marks (four basis points).  Also contributing to the increase in the net interest margin was an increase in loan fees and the Fed’s 25 basis point increase to rates in December 2016.

NON-INTEREST INCOME

The Company’s non-interest income was $13.4 million for the fourth quarter of 2016 compared to $12.7 million for the same period in 2015. An increase in mortgage banking income of $1.3 million was partially offset by a decrease of $409 thousand in service charges on deposit accounts. 

NON-INTEREST EXPENSE

The Company’s non-interest expense was $28.9 million for the fourth quarter of 2016 compared to $26.2 million for the same period in 2015.  The year over year increase in total expenses were in the employee, occupancy and equipment expense categories and were primarily related to the acquisition of Cheviot in May 2016.  The Company also made year-end accrual adjustments to incentive compensation expense based on the strong performance in the fourth quarter. 

BALANCE SHEET AND CAPITAL

Total assets were $4.1 billion at December 31, 2016, which represents a $695 million increase from a year ago.  The increase in assets was primarily related to the acquisition of Cheviot ($563 million) and organic loan growth.  Loan balances (including loans that are classified as held for sale) grew $72 million on a linked quarter basis which represents an 11% increase on an annualized basis.  The Company’s regulatory capital ratios remain strong and as of December 31, 2016 were as follows: leverage ratio of 9.7%, tier one capital to risk-weighted assets of 13.8%, common equity tier one capital ratio of 12.3%, and total capital to risk-weighted assets of 14.6%.  In addition, as of December 31, 2016, the Company’s tangible common equity ratio was 8.6% compared to 9.0% as of September 30, 2016.  The decrease in the tangible common equity ratio was related to the decrease in the market valuation of the Company’s investment securities portfolio and the resulting decrease in accumulated comprehensive income portion of equity.

ASSET QUALITY

Non-performing assets (NPAs) were $23.1 million as of December 31, 2016, an increase of $2.6 million on a linked-quarter basis.  The increase in NPAs was primarily related to one $2.1 million relationship that became 90+ days past due at year-end due to the maturity of the related notes, which have since been renewed and this relationship is no longer considered non-performing.  NPAs represented 0.57% of total assets as of December 31, 2016 compared to 0.51% as of September 30, 2016 and 0.53% as of December 31, 2015.  The Company incurred net charge-offs of $179 thousand and recorded $850 thousand of loan loss provision expense for the fourth quarter of 2016.  This level of provision expense resulted from the organic loan growth realized during the period.  The Company’s allowance for loan losses as a percent of total outstanding loans was 0.84% as of December 31, 2016 compared to 0.84% as of September 30, 2016 and 1.02% as of December 31, 2015.  The decrease in this metric year over year was primarily driven by the increase in acquired loans that were marked to fair value at the acquisition date and not included in the loan loss reserve analysis.

USE OF NON-GAAP FINANCIAL MEASURES

This press release includes financial measures prepared other than in accordance with generally accepted accounting principles in the United States (“GAAP”).
