The story
The bank was founded in 1834 as a branch of the Second State Bank of Indiana and later became known as Terre Haute First National Bank. In 1983, First Financial Corporation was established as the bank's holding company, and in August 1984 it became Indiana's first multi-bank holding company. After mergers and acquisitions, the various banks affiliated as First Financial Bank in 2003.
For most of its existence, First Financial operated largely in the Indiana and Illinois counties around Terre Haute, but two recent mergers greatly expanded the corporation's footprint into Kentucky.
As a result of the mergers in 2019 and 2021, First Financial Bank now operates banking centers and loan production offices in Indiana, Illinois, Kentucky and Tennessee.

The deal, which added branch locations in Hawesville, Lewisport, Madisonville, Cloverport and Bowling Green in Kentucky to the First Financial portfolio, was valued at $31.3 million ($18.38/share).
