## History

First Financial Bank, N.A., was founded in 1863 as the First National Bank of Hamilton and was granted charter number 56 on August 10, 1863, under the National Bank Act. The bank opened its first branch in Hamilton, Ohio and started business on August 15, 1863. In 1923, the bank's name was changed to First National Bank and Trust Company of Hamilton when the trust division was created.

In 1980, the First National Bank of Hamilton consolidated operations with the First National Bank of Middletown to form the First National Bank of Southwestern Ohio. The acquisition of smaller institutions allowed it to expand outside Butler County. First Financial Bancorp, a holding company, was formed in 1983.

In 2008, First Financial Bancorp relocated its headquarters to Norwood while the headquarters for the bank remained in Hamilton. The following year, the holding company moved their headquarters to the Atrium One building in Downtown Cincinnati before finally settling into the Chemed Center building, renamed First Financial Center, in 2011.

In July 2017, First Financial agreed to purchase Greensburg, Indiana based MainSource Bank for $1 billion, making First Financial the fourth-largest bank in Cincinnati, and the second-largest local bank. The combined organization will continue to be called First Financial Bancorp. The acquisition was finalized on April 2, 2018. All MainSource computer systems and deposits were transitioned to First Financial on May 29, 2018.
