Jeff Davis Bancshares, the financial holding company of Jeff Davis Bank & Trust Co. of Jennings, has completed its acquisition of Mamou-based Guaranty Bank in a cash transaction valued at $20.9 million.

The bank has a branch facility at the corner of Park Avenue & South 3rd St. in Eunice, as well as offices in Mamou, Ville Platte and Vidrine.

Jeff Davis Bank announced in October plans to acquire Guaranty, a state-chartered commercial bank with $143 million in assets, $126 million in deposits.

The deal closed as scheduled Monday, Dec. 31, with approval from industry regulators, giving Jeff Davis Bank 18 branches and about $703 million in assets.

Robert J. Marcantel was president and CEO of Guaranty.

Dan. L. Donald, Jr. a member of the Jeff Davis board since 1979, is JD Bancshares chairman.

“We welcome our new customers into the Jeff Davis Bank family,” says Boyd Boudreaux, president and CEO. “Our priority is the highest level of convenience and service that comes only with community banking.”

Through its wholly owned subsidiary, Jeff Davis Bank & Trust Co., founded in Jennings in 1947, Jeff Davis Bancshares offers full service personal and business banking throughout Southwest Louisiana.

According to filings regarding the acquisition, Guaranty, which began operation on Aug. 1, 1950, has 53 full time equivalent positions. It opened its Eunice office in July 1967.
