Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On December 17, 2019, the board of directors (“Board”) of Simmons First National Corporation (the “Company”) elected Marty Casteel to the Board, effective January 1, 2020, to fill the vacancy on the Board resulting from the resignation of Christopher Kirkland (which is effective December 31, 2019, and was further described in the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on October 18, 2019). Mr. Casteel will serve on the Board’s risk committee.

Mr. Casteel currently serves as Senior Executive Vice President of the Company and as Chairman, President and CEO of the Company’s wholly owned bank subsidiary, Simmons Bank. He has been employed by Simmons Bank for over 30 years.

Because, and so long as, Mr. Casteel is an employee of the Company, he will not receive separate compensation for his service as a member of the Board. There is no arrangement or understanding between Mr. Casteel and any other person pursuant to which Mr. Casteel was elected to the Board. Other than loans and extensions of credit that have been made from time to time by Simmons Bank in the ordinary course of business on substantially the same terms (including interest rates and collateral) as those prevailing at the time for comparable transactions with other persons not related to Simmons Bank and did not involve more than the normal risk of collectability or present other unfavorable features, Mr. Casteel is not a party to any transactions with the Company required to be disclosed pursuant to Item 404(a) of Regulation S-K.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
