NEWS RELEASE [FIRST FINANCIAL CORPORATION LOGO] FIRST FINANCIAL CORPORATION One First Financial Plaza, Terre Haute, IN 47807 o (812) 238-6000 FOR IMMEDIATE RELEASE For more information contact: August 1, 2005 Michael A. Carty at (812) 238-6264 FIRST FINANCIAL CORPORATION REPORTS SECOND QUARTER EARNINGS OF $.37 PER SHARE TERRE HAUTE, INDIANA - First Financial Corporation (NASDAQ:THFF) today announced the results for the second quarter of 2005 with net income for the three-month period ended June 30, 2005 of $5.0 million or $.37 per share. Earnings for the six-months ended June 30, 2005 are $11.3 million. Loans at June 30, 2005 increased $1.7 million to $1.46 billion and deposits increased $59.6 million to $1.49 billion from the previous year quarter end. Rising interest rates have had a positive impact on the Corporation's net interest income, which for the first six months of 2005 increased by $935 thousand or 2.62% over the same period in 2004. The net interest margin increased to 3.95% for the six-months ended June 30, 2005 from 3.77% for the same period in 2004. This 4.8% increase was driven by growth in the yield on earning assets which outpaced the average cost of funds. The modest amount of loan growth for the year has allowed the Corporation to direct attention to aggressively addressing some potential asset quality concerns during the second quarter. Letters of intent to sell several non-performing loans were entered into during the period. This has resulted in larger than normal net charge-offs for the quarter, as these loans will be sold at a discount. This will allow the Corporation to reinvest the proceeds into performing assets to improve future results. A $1.5 million addition to the allowance for loan and leases losses was made to recognize the additional losses resulting from this decision. At period end the allowance was 1.2% of loans outstanding. Non-interest income for the second quarter of 2005 was $7.8 million compared to $8.3 million for the same period in 2004. This reduction of approximately $500 thousand primarily resulted from $391 thousand less gain on the sale of investment securities for the 3 months ended June 30, 2005 compared to the same period of 2004. The year-to-date non-interest income is $5.4 million less than last year's performance largely as a result of the previously reported non-taxable gain on life insurance realized in the first quarter of 2004. Benefits continue to be realized from the consolidation of affiliate banks into one bank as second quarter non-interest expense was lower than the same period in 2004. Non-interest expense for the second quarter and the six-months ended June 30, 2005 is $95 thousand and $286 thousand less, respectively, than the same periods in 2004. Seven of the eight subsidiary banks have completed the consolidation process and now operate as First Financial Bank. A $59.6 million or 4.2% increase in deposits from June 30, 2004 to June 30, 2005 was used to fund loans and reduce borrowings. Average assets decreased $70.7 million, or 3.19%. The decrease primarily resulted from the Corporation's use of maturing investments to retire debt. Shareholder's equity increased $8.7 million, or 3.3%, and book value per share rose by $.79 to $20.04, or 4.1%. First Financial Corporation is the holding company for First Financial Bank NA in Indiana and Illinois; The Morris Plan Company of Terre Haute and Forrest Sherer Inc. in Indiana; and First Community Bank NA in Illinois.
