LAFAYETTE, LA., January 31, 2017/PRNewswire-FirstCall/ -- MidSouth Bancorp, Inc. (“MidSouth”) (NYSE:MSL) today reported quarterly net earnings available to common shareholders of $1.4 million for the fourth quarter of 2016, compared to net earnings available to common shareholders of $1.7 million reported for the fourth quarter of 2015 and $1.6 million in net earnings available to common shareholders for the third quarter of 2016. Diluted earnings for the fourth quarter of 2016 were $0.12 per common share, compared to $0.15 per common share reported for the fourth quarter of 2015 and $0.14 per common share reported for the third quarter of 2016.

Troy Cloutier, MidSouth Bank President and CEO, commenting on fourth quarter earnings remarked, "We continue to work diligently to support our energy-related customers through this cycle and at the same time look to minimize risk to our balance sheet. Our loss content during the past two years has been modest with cycle-to-date charge-offs of 1.23% of energy loans. More importantly, we are focused on improving performance in non-energy related lending and are very excited with new hires we have made in the latter part of 2016, especially in our Texas markets.”

Energy Lending Update

MidSouth Bank defines an energy loan as any loan where the borrower's ability to repay is disproportionately impacted by a prolonged downturn in energy prices. Under this definition, the Bank includes direct Commercial and Industrial (C&I) loans to energy borrowers, as well as Commercial Real Estate (CRE) loans, Residential Real Estate loans and loans to energy-related borrowers where the loan's primary collateral is cash and marketable securities. Although this definition has resulted in a lack of comparability with some other energy-related banks, management believes it to be the prudent approach to monitoring and managing the Bank's energy exposure.

C. R. Cloutier, MidSouth Bancorp President and CEO stated, "We are encouraged with the higher pricing levels for oil and natural gas in addition to the recent Executive directives to expedite both the reopening of the Keystone pipeline and ordering permits for the Dakota access pipeline. Furthermore, signs of regulatory relief appear to be forthcoming, all of which should be beneficial to our energy-related customers."

Balance Sheet

Consolidated assets totaled $1.9 billion at December 31, 2016 and 2015, compared to $2.0 billion at September 30, 2016. Our stable core deposit base, which excludes time deposits, totaled $1.4 billion at December 31, 2016 and September 30, 2016 and accounted for 90.0% of

2

deposits at December 31, 2016 and September 30, 2016. Net loans totaled $1.3 billion at December 31, 2016, compared to $1.2 billion at September 30, 2016 and December 31, 2015.

MidSouth’s Tier 1 leverage capital ratio was 10.11% at December 31, 2016, compared to 10.27% at September 30, 2016. Tier 1 risk-based capital and total risk-based capital ratios were 13.02% and 14.28% at December 31, 2016, compared to 13.07% and 14.33% at September 30, 2016, respectively. Tier 1 common equity to total risk-weighted assets at December 31, 2016 was 8.81%, compared to 8.83% at September 30, 2016. Tangible common equity totaled $126.5 million at December 31, 2016, compared to $129.9 million at September 30, 2016. Tangible book value per share at December 31, 2016 was $11.13 versus $11.44 at September 30, 2016 primarily due to a $4.3 million decline in other comprehensive income during the quarter.

Asset Quality

Nonperforming assets totaled $65.0 million at December 31, 2016, an increase of $949,000 compared to $64.1 million reported at September 30, 2016. The increase is primarily attributable to a $2.1 increase in loans on nonaccrual, which was partially offset by a $700,000 decrease in loans past due ninety days and over and accruing. Allowance coverage for nonperforming loans increased to 38.78% at December 31, 2016, compared to 37.84% at September 30, 2016. The ALLL/total loans ratio was 1.90% at December 31, 2016 and 1.83% at September 30, 2016. Including valuation accounting adjustments on acquired loans, the total valuation accounting adjustment plus ALLL was 2.06% of loans at December 31, 2016. The ratio of annualized net charge-offs to total loans increased to 0.46% for the three months ended December 31, 2016 compared to 0.32% for the three months ended September 30, 2016.

Total nonperforming assets to total loans plus ORE and other assets repossessed was 5.06% at December 31, 2016 compared to 5.03% at September 30, 2016. Loans classified as troubled debt restructurings, accruing (“TDRs, accruing”) totaled $152,000 at December 31, 2016 and $153,000 at September 30, 2016. Classified assets, including ORE, increased $15.6 million, or 13.2%, to $134.2 million at December 31, 2016 compared to $118.6 million at September 30, 2016. The increase in classified assets during the quarter ended December 31, 2016 is primarily due to the downgrade of six energy-related credits totaling $19.8 million and the downgrade of one credit not related to energy totaling $4.3 million. These increases to classified assets were partially offset by the payoff of $8.1 million classified relationship during the fourth quarter.

Fourth Quarter 2016 vs. Third Quarter 2016 Earnings Comparison

In sequential-quarter comparison, net earnings available to common shareholders decreased $200,000, from $1.6 million for the three months ended September 30, 2016 to $1.4 million for the three months ended December 31, 2016. Net interest income decreased $15,000 in sequential-quarter comparison. Noninterest income decreased $84,000 in sequential-quarter comparison. The decrease in noninterest income consisted primarily of a $110,000 decrease in service charges on deposit accounts and a $26,000 decrease in mortgage program fee income, which were partially offset by a $62,000 increase in ATM/debit card income.

Noninterest expense increased $522,000 in sequential-quarter comparison, which was primarily due to increased costs of $362,000, or $0.02 per share, related to recruiting new talent to the

3

organization, including new producers in Texas and a new Chief Information Officer. The increase in noninterest expense consisted primarily of increases of $692,000 in salaries and benefits costs, a $96,000 in occupancy expense and an $89,000 increase in loss on sale of other assets repossessed, which were partially offset by a $93,000 decrease in marketing expense and a $274,000 decrease in shares tax expense. The provision for loan losses decreased $300,000 in sequential-quarter comparison.

Dividends on the Series B Preferred Stock issued to the Treasury as a result of our participation in the Small Business Lending Fund (“SBLF”) totaled $720,000 for the fourth quarter of 2016 based on a dividend rate of 9%. Dividends on the Series C Preferred Stock issued with the December 28, 2012 acquisition of PSB Financial Corporation (“PSB”) totaled $92,000 for the three months ended December 31, 2016.

Fully taxable-equivalent (“FTE”) net interest income increased $9,000 in sequential-quarter comparison. Interest income on loans decreased $25,000 due to a decrease in the average yield on loans of 5 basis points, from 5.45% to 5.40%. The average balance of loans increased $9.3 million in sequential-quarter comparison. Excluding purchase accounting adjustments, the loan yield decreased 3 basis points, from 5.31% to 5.28% during the same period. The average yield on total earning assets decreased 7 basis points for the same period, from 4.55% to 4.48%, respectively.

Noninterest expenses increased $128,000 in quarterly comparison and consisted primarily of a $482,000 increase in salaries and employee benefits costs, a $54,000 increase in recruiting expense and a $102,000 increase in loss on sale of other assets repossessed, which was partially offset by a $123,000 decrease in FDIC premiums, a $240,000 decrease in shares tax expense, a $103,000 decrease in marketing expense and a $57,000 decrease in printing and supplies costs. The increases in salaries and benefits expense and recruiting expense were attributable primarily to the cost of locating and hiring several new key employees. The increase in salaries and benefits costs included $124,000 of sign-on bonuses for these employees, and we also recorded $100,000 of recruiting expenses during the three months ended December 31, 2016 related to these employees.

Reconciliation of Non-GAAP Financial Measures (unaudited)
(in thousands except per share data)
Certain financial information included in the earnings release and the associated Condensed Consolidated Financial Information (unaudited) is determined by methods other than in accordance with GAAP. We are providing disclosure of the reconciliation of these non-GAAP financial measures to the most comparable GAAP financial measures. "Tangible common equity" is defined as total common equity reduced by intangible assets. "Core net interest margin" is defined as reported net interest margin less purchase accounting adjustments. "Annualized return on average assets, operating" is defined as net earnings available to common shareholders adjusted for specified one-time items divided by average assets. "Annualized return on average common equity, operating" is defined as net earnings available to common shareholders adjusted for specified one-time items divided by average common equity. "Annualized return on average tangible common equity, operating" is defined as net earnings available to common shareholders adjusted for specified one-time items divided by average tangible common equity. "Pre-tax, pre-provision annualized return on average assets, operating" is defined as pre-tax, pre-provision earnings adjusted for specified one-time items divided by average assets. "Tangible book value per common share" is defined as tangible common equity divided by total common shares outstanding. "Diluted earnings per share, operating" is defined as net earnings available to common shareholders adjusted for specified one-time items divided by diluted weighted-average shares. The GAAP-based efficiency ratio is measured as noninterest expense as a percentage of net interest income plus noninterest income. The non-GAAP efficiency ratio excludes specified one-time items in addition to securities gains and losses and gains and losses on the sale/valuation of other real estate owned and other assets repossessed.
We use non-GAAP measures because we believe they are useful for evaluating our financial condition and performance over periods of time, as well as in managing and evaluating our business and in discussions about our performance. We also believe these non-GAAP financial measures provide users of our financial information with a meaningful measure for assessing our financial condition as well as comparison to financial results for prior periods. These results should not be viewed as a substitute for results determined in accordance with GAAP, and are not necessarily comparable to non-GAAP performance measures that other companies may use.
