People's Utah Bancorp in American Fork is buying Lewiston Bancorp in Lewiston, Utah.
People's did not disclose the price it will pay for the $252 million-asset Lewiston. The companies expect to complete the deal in the fourth quarter.
Lewiston's four branches in Utah and Idaho will continue to operate under the bank's name after the merger. People's is the parent of the $949 million-asset Bank of American Fork, which has 13 Utah branches.
The companies will retain separate boards, with two members of each company's board joining the other.
"Blending the talented management and staff of both banks helps put People's Utah Bancorp in a clear position as Utah's community bank leader in service, asset size and deposit size," Richard Beard, People's president and chief executive, said in a press release Tuesday. "This combination will help grow and foster the local community banking system that is vital to the economy, small businesses and Utah communities."
D.A. Davidson advised People's; Sandler O'Neill advised Lewiston.
