Item 2.02 Results of Operations and Financial Condition.

On October 23, 2007, First Financial Bancorp. issued its earnings press release that included the results of operations and financial condition for the third quarter of 2007. A copy of the earnings press release is attached as Exhibit 99.1.

First Financial Bancorp. does not intend for this Item 2.02 or Exhibit 99.1 to be treated as “filed” for purposes of the Securities Exchange Act of 1934, as amended, or incorporated by reference into its filings under the Securities Act of 1933, as amended.

The earnings press release includes two non-GAAP financial measures. The first non-GAAP financial measure, Net interest margin (fully tax equivalent), appears in the table entitled “Consolidated Financial Highlights” under the section “Key Financial Ratios.” The second appears in the tables entitled “Additional Data” at the bottom of the “Consolidated Statements of Income” and “Consolidated Quarterly Statements of Income” pages. The tax equivalent adjustment to net interest income recognizes the income tax savings when comparing taxable and tax-exempt assets and assumes a 35% tax rate. Management believes that it is a standard practice in the banking industry to present net interest margin and net interest income on a fully tax equivalent basis. Therefore, management believes these measures provide useful information to investors by allowing them to make peer comparisons. Management also uses these measures to make peer comparisons.

Below is a table showing “net interest income” calculated and presented in accordance with GAAP and the adjustments made to arrive at the non-GAAP financial measure “net interest income — tax equivalent.” The table also shows “net interest margin” calculated and presented in accordance with GAAP and the method used to arrive at the non-GAAP financial measure “net interest margin (fully tax equivalent).”
