We intend to retain the existing employees at the branch as they will make the transition as easy as possible for our new customers coming from DB&T. The transaction is expected to be immediately accretive to earnings.”

“With the announcement of the sale of this location, we are hopeful that we will receive the remaining necessary regulatory approvals to complete the acquisition of DB&T," said Bob Montgomery-Rice, President & Chief Executive Officer of Bangor Savings Bank. "Our team will work closely with First National Bank in the conversion process to support employees, customers, and our community through the transition. We look forward to continuing to serve existing Bangor Savings Bank customers in Belfast.”

The final value of the transaction is estimated to be $24.8 million, which includes the loans, an assignment of a ground lease, leasehold improvements, and furniture and equipment for the Belfast location, plus the premium paid for the deposits. The transaction is subject to regulatory approval and is expected to close in the fourth quarter of 2020 after completion of the pending DB&T acquisition. Over the next several weeks, First National and DB&T will be communicating directly with customers of the Belfast branch to guide them through the process and assist with any questions.
