Tex. Finance Code § 32.301

(a) Two or more financial institutions, corporations, or other entities with the authority to participate in a merger, at least one of which is a state bank, may adopt and implement a plan of merger in accordance with this section. The merger may not be made without the prior written approval of the banking commissioner if any surviving, new, or acquiring entity that is a party to the merger or created by the terms of the merger is a state bank or is not a financial institution.

(b) Implementation of the merger by the parties and approval of the board, shareholders, or owners of the parties must be made or obtained in accordance with the Business Organizations Code as if the state bank were a filing entity and all other parties to the merger were foreign entities, except as may be otherwise provided by applicable rules.

(c) A consummated merger has the effect provided by the Business Organizations Code. A separate application is not required to relocate the home office of a surviving state bank or to grant authority to a surviving bank to operate new branch offices that previously existed as part of a merging financial institution if the intent of the surviving bank is clearly stated as part of the plan of merger.

(d) A merger under this subchapter does not confer additional powers on a state bank beyond the powers conferred by other provisions of this subtitle.
