American Trust Bank, headquartered in Roswell, was closed by state regulators on Friday.
According to a news release, all the bank's deposits and accounts were sold by the Federal Deposit Insurance Corp., or FDIC, to Renasant Bank of Tupelo, Miss.
All American Trust locations, including one at 601 Tri-County Plaza in Cumming, will open at their normal banking hours Monday as Renasant Bank.
In addition to the Roswell and Cumming locations, American Trust Bank had a third location in Alpharetta.
Renasant Chairman and CEO E. Robinson McGraw said in a statement that "the chance to acquire American Trust was a tremendous opportunity to expand Renasant Bank's presence in north Georgia."
American Trust clients will continue to be able to conduct banking business, including accessing their money by writing checks and using ATM or debit cards.
All outstanding checks will be processed as usual and customers can continue using their American Trust checks, according to the release.
