FIRST GUARANTY BANCSHARES, INC. AND UNION BANCSHARES, INCORPORATED AGREE TO MERGE

HAMMOND, LA, August 5, 2019 – First Guaranty Bancshares’ strong, steady growth and continued rise in shareholder value took another big step forward today with the announcement that Union Bancshares, Incorporated. (Union) and its wholly owned subsidiary, The Union Bank, have agreed to join and become a part of First Guaranty Bancshares, Inc.  According to the terms of the agreement, First Guaranty will acquire all of the outstanding common stock of Union in a transaction valued at approximately $43 million.

Union is a strong and well managed institution located in Central Louisiana with seven locations.  Besides adding strong assets and enhanced profitability, this acquisition will solidify First Guaranty Bancshares’ footprint by providing a profitable link between First Guaranty’s South Louisiana operations and First Guaranty’s North Louisiana and Texas operations.

“This is a very significant, positive move for First Guaranty. Darrel D. Ryland, the Board of Directors, and the staff of The Union Bank have built a very strong and profitable financial institution in the center of Louisiana. This acquisition will move First Guaranty into a part of Louisiana where we have never done business and also tie together all of our operations from north, south, and Texas. This move will provide great momentum with First Guaranty moving forward with our plans for continued growth and continued improvement in shareholder value,” said Alton Lewis, President and Chief Executive Officer of First Guaranty.

Under the terms of the agreement, First Guaranty will acquire Union for an aggregate purchase price of approximately $43 million.  The aggregate purchase price is based on 1.5 times Union’s estimated tangible book value at September 30, 2019.  The aggregate consideration paid to stockholders of Union will be 100% cash.  Completion of this transaction is expected in late fourth quarter of 2019 and is subject to certain closing conditions, including Union stockholder approval and customary regulatory approvals.  After closing, Union and its subsidiary The Union Bank will fully merge into First Guaranty.
