Mainsource Banks Change Over To First Financial Banks

Signs change in Madison and Hanover

 A merger between Mainsource Bank and First Financial Bank has been completed.

The two banks announced April 2 that the deal first announced in July 2017 has been cinched up. MainSource official became part of First Financial on April 1.

The newly combined company will operate as First Financial Bank, with total assets of $14 billion. With the merger done, First Financial Bank is now the fourth-largest bank in the Cincinnati market.

Mainsource Bank signs have been replaced by First Financial Bank signs in both Madison and Hanover.

MainSource Bank branches will continue to operate under the MainSource name until operating system conversions are completed this spring. Branding and sign changes are already taking place at some former MainSource branches.

All MainSource branches will be closed on Saturday, May 26 so the system switch can be made that weekend. Those banking centers will reopen on Tuesday, May 29 – the day after the Memorial Day banking holiday – under the First Financial brand.

The newly merged bank’s customers will receive a welcome guide with more information on the transition soon. They will gain access to 150 branches and 55,000 ATMs.
