This amended statement is filed on behalf of Trustmark National Bank, in its capacity as trustee of the Sanderson Farms, Inc. and Affiliates Employee Stock Ownership Plan (the “ESOP”). As of December 31, 2014, the ESOP was the record owner of 1,694,201 shares of common stock of the Company, representing approximately 7.5% of the Company’s outstanding common stock.

With respect to unallocated shares and shares for which the Trustee does not receive timely and proper voting directions from participants, the trustee must vote in the same proportion, for and against propositions submitted to the vote of the shareholders, as the Trustee votes shares for which it receives timely and proper directions. The Trustee makes distributions of shares to participants in accordance with the plan terms and may sell shares from time to time to meet the plan’s cash needs. Participants are entitled to direct the Trustee whether to tender the shares allocated to their accounts in response to a tender offer. The Trustee may not tender any shares (including unallocated shares) for which it does not receive timely and proper directions.
