Miss. Code § 81-7-11
Subject to the provisions of subsections (2), (3) and (4) of Section 81-7-8, a bank may annex actively operating unit banks as branch banks by exchanging its own increase of common or preferred capital shares, issued for such annexation purpose, for the capital shares of the bank proposed to be annexed as a branch. Also a bank may annex branch banks by issuing additional common or preferred shares to be exchanged for the assets of closed banks, including assets other than cash. All transactions authorized by this section shall first be submitted in writing in full detail to the commissioner, and shall not be effective until he shall have made a careful analysis and investigation of the soundness of the proposed transaction, and shall have approved the same in writing. In no instance, however, shall the bank building and fixtures of the operating or closed bank, proposed to be annexed as a branch bank, represent in value more than one-third (1/3) of the amount of stock issued by the parent bank for the purpose of such annexation. For purposes of applying the restrictions of subsections (2) and (3) of Section 81-7-8, the annexation of an actively operating unit bank described herein shall be considered the establishment of a branch by merger.
