DECATUR, Ill.–Land of Lincoln Credit Union said it has entered into an agreement to purchase the $97-million Williamsville State Bank and Trust of Williamsville, Ill., and wholly-owned subsidiary of WSB Financial, Ltd.
It is an all-cash transaction, according to the two parties, although terms of the deal were not released.
According to the $477.6-million Land of Lincoln CU, while the agreement is contingent on obtaining regulatory and WSB Financial, Ltd. stockholder approvals, the proposed transaction has been unanimously approved by the boards of both institutions and is expected to close in the first half of 2026.
