Item 1. Security and Issuer.

The name of the issuer is MidSouth Bancorp, Inc. (the "Issuer").  The address of the Issuer's principal executive offices is 102 Versailles Boulevard Lafayette, LA 70501.  This Schedule 13D relates to the Issuer's Common Stock, par value $0.10 (the "Shares").

Item 2.	Identity and Background.
	(a-c, f) This Schedule 13D is being filed jointly by Sy Jacobs, a United States citizen, and Jacobs Asset Management, LLC, a Delaware limited liability company (the “Reporting Persons”).  The principal business address of the Reporting Persons is 11 East 26th Street, Suite 1900, New York, New York 10010.
	(d) There were no criminal proceedings during the last five years referred to in Item 2(d), in which the Reporting Persons or their executive officers were convicted (excluding traffic violations or similar misdemeanors).
	(e)  None of the Reporting Persons has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

The funds used for the purchase of the Shares came from the working capital of the clients of Jacobs Asset Management, LLC. No borrowed funds were used to purchase the Shares, other than any borrowed funds used for working capital purposes in the ordinary course of business.

Item 4. Purpose of Transaction.

The Reporting Persons are increasingly frustrated with the performance of the Issuer and the lack of action taken by the Issuer’s Board of Directors to create shareholder value.  Given the value of Issuer's franchise to a large number of potential acquirers, the Reporting Persons believe the board has a fiduciary responsibility to pursue a sale, as described in the letter that the Reporting Persons sent to the Issuer’s Board of Directors on August 15, 2018, attached hereto as Exhibit C.  If the Issuer does not, the Reporting Persons look forward to exercising their rights as shareholders at next year’s annual meeting.

The Reporting Persons, however, reserve the right, at a later date, to effect one or more of such changes and may dispose of or enter into other transactions in the shares they may be deemed to beneficially own.

The Reporting Persons reserve the right to be in contact with members of the Issuer's management, the Issuer's Board of Directors, other significant shareholders and others regarding alternatives that the Issuer could employ to maximize shareholder value.

The Reporting Persons further reserve the right to act in concert with any other shareholders of the Issuer, or other persons, for a common purpose should it determine to do so, and/or to recommend courses of action to management and the shareholders of the Issuer.

The Reporting Persons have acquired their Shares of the Issuer for investment. The Reporting Persons have no plans or proposals as of the date of this filing which, other than as expressly set forth below, would relate to or would result in: (a) any extraordinary corporate transaction involving the Issuer; (b) any change in the present Board of Directors or management of the Issuer; (c) any material change in the present capitalization or dividend policy of the Issuer; (d) any material change in the operating policies or corporate structure of the Issuer; (e) any change in the Issuer's charter or by-laws; (f) the Shares of the Issuer ceasing to be delisted from a national securities exchange or to ceasing to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; or (g) causing the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934.

Item 5. Interest in Securities of the Issuer.

(a-e)  As of the date hereof, Sy Jacobs may be deemed to be the beneficial owner of 1,166,457Shares (7%) of the Issuer, based upon the 16,639,650 Shares outstanding as of August 9, 2018, according to the Issuer.  Sy Jacobs has the sole power to vote or direct the vote of 0 Shares, the shared power to vote or direct the vote of 1,166,457 Shares, the sole power to dispose or direct the disposition of 0 Shares and the shared power to dispose or direct the disposition of 1,166,457 Shares to which this filing relates.

The Board of Directors of MidSouth Bancorp Inc.

c/o Jake Delhomme, Chairman of the Board of Directors

102 Versailles Boulevard

Lafayette, LA 70501

Dear Mr. Delhomme,

I am writing to you in your capacity as Chairman of the Board of MidSouth Bancorp (MidSouth, MSL or the Bank) and ask that you distribute this letter to your fellow board members. I am the founding and managing partner of Jacobs Asset Management (JAM), the investment manager of several partnerships that have been shareholders of MidSouth since 2009. In total, JAM's affiliated entities own 7.0% of MSL's shares outstanding, making us the second largest shareholder.

This letter will be a matter of public record, as we are attaching it to a 13D that will be filed with the SEC tomorrow.

In brief, this letter will highlight our long-running and increasing frustration with the performance of the Bank and the lack of action taken to create shareholder value. We believe there is a clear path to doing so, but instead, management and the board seem content producing poor results and no shareholder value.

Investors in Financial Services

By way of background, we manage partnerships that invest in U.S. financial services companies, including a concentration in depository institutions. We have $650 million of assets under management and have been in business for more than 23 years. In that time, we have always sought to invest with management teams and boards that act to create shareholder value. Our intention is to be a passive and supportive investor, and we typically work with companies in pursuing our mutual interests – often directly providing capital for turnaround efforts, organic growth or acquisitions. But a few times in our history we have found it necessary to send a letter such as this urging a bank board to pursue a different path to creating shareholder value. In these cases, just as with MSL, we were long-time shareholders frustrated by the diverging interests between shareholders and the board. In two instances I fought my way on to the boards.

We were introduced to Rusty Cloutier and Jim McLemore in 2009, when MidSouth was raising capital to acquire smaller institutions and take advantage of the distressed bank opportunity after the Great Recession. We were supportive of these plans, and by participating in that capital raise and subsequent open market purchases we soon became the largest shareholder of MSL. As you know, the Bank's plans went awry as growth slowed, inefficiencies emerged and credit deteriorated. When Rusty was terminated as CEO in 2017 your management team, including interim CEO Jim McLemore, held calls and meetings with analysts and investors where a turnaround and growth plan was discussed. MidSouth raised capital again to implement its strategy and, so we were told, redeem its SBLF preferred (which had just increased in cost from 1% to 9% annually).

Once again, these plans have gone awry, as the metrics and timelines laid out have already been missed and new problems have emerged. Aside from not using the capital raised to pay off the expensive SBLF preferred, a couple of instances of fresh missteps stick out from a list of many. We were told that the board had been frustrated with the slow pace of resolving problem assets and Jeff Blum, the newly appointed Chief Lending Officer, would lead the effort to be more aggressive in this regard. The stated goal was to get the classified asset ratio below 40% by the end of 2017. When the year ended, classified assets remained well above 40% and Jeff Blum had left. Six months later, MSL's classified asset ratio is a stubbornly high 53%. In our last meeting with management in May 2018, and also in the second quarter earnings release, the conversation shifted from improved credit, efficiency and growth to necessary and increasingly costly remediation efforts.

Clearly the restructured board and management team had a poor grasp on the scope of the turnaround plan necessary when capital was raised in 2017. Given how badly the plan has gone we question whether there was purposeful deception or just plain delusion. Wherever the truth lies, you have blown your second chance with shareholders and don't deserve to remain independent.

Before I discuss the path to maximizing shareholder value that I believe the board must undertake, let's look back at returns over the last 9 years. The table on the following page shows the performance of MSL stock over 3 different time periods, including just before your 2009 and 2017 capital raises and the peak of oil prices in 2014. We compare MSL's performance to the KBW Regional Banking Index, the Nasdaq Bank Index and the median returns of seven banks, mostly in your region, that had 7.5% or more of their loan portfolio in the energy sector as of Q314.

 

You see that MSL's performance has been abysmal in all of these time periods versus all comparables. Cumulatively, MSL's 22% rise since 11/25/09 (an IRR of just 2.3%) compares to increases of 187-229% for the others. Your management team has often referenced the decline in energy prices as the cause of your underperformance, but you can see that since the 2014 peak of oil prices MSL's 26% decline compares to an increase of 62% in the basket of energy-exposed banks.

Having shown how poorly shareholders have fared under the board's stewardship, I propose a different path. While MSL has reported substantial losses over the last 18 months, the rest of the U.S. banking industry has enjoyed record profits and stock valuations have soared. The pace of consolidation has picked up as those banks worthy of their independence have used their appreciated currencies to accretively buy other banks.

While poor operating results have caused MSL shareholders to suffer, we have gotten quite lucky that the value of MSL to another institution has actually increased due to tax reform, a better banking environment and robust acquirer valuations. Using a standard ability-to-pay analysis of five acquisitive banks in your region that we believe would be interested in buying MSL, we estimate that the average price they could pay while achieving a tangible book value earn-back under four years is approximately $19-20 per share. Similarly, using a deposit premium-based approach we estimate that a reasonable 10-15% deposit premium for MSL's highly desirable, low-cost and sticky deposit base in LA and TX would result in a price of $19-23 per share.

When we consider the opportunity to swap, at approximately a 50% premium to market, out of an unprofitable, shrinking, inwardly-focused bank into any number of profitable, growing banks, we think it is clear that MSL's board has a fiduciary responsibility to pursue such a path. If it does not, we look forward to exercising our rights as shareholders and having our voice and vote heard at next year's annual meeting.
