AmSouth Reports Record Second Quarter 2005 Earnings

BIRMINGHAM, Ala., July 19, 2005 – AmSouth Bancorporation (NYSE: ASO) today reported earnings for the second quarter ended June 30, 2005, of $.52 per diluted share, compared to $.47 per diluted share reported for the second quarter of 2004. Net income for the second quarter of 2005 was a record $184.6 million versus $167.0 million for the same period in 2004, an increase of 10.6 percent.

This second quarter performance resulted in a return on average equity of 20.9 percent, a return on average assets of 1.47 percent, and an improved efficiency ratio of 51.4 percent.

“AmSouth generated solid, high quality results this quarter,” said Dowd Ritter, AmSouth’s chairman, president and chief executive officer. “We saw strong performance across the board: good loan production and deposit growth, extremely strong credit quality and disciplined expense control.”

Net interest income was $378.6 million in the second quarter, a 4.8 percent increase compared with the same quarter in 2004. The net interest margin in the second quarter was 3.40 percent, which is a 4 basis point decline compared with the same period in 2004. The increase in net interest income in the second quarter was driven by solid loan growth supported by continued strength in deposits, particularly in the low-cost category. Commercial loans grew 12.8 percent compared with the same quarter in 2004, and low-cost deposits increased 15.1 percent during the same period.

Noninterest revenue, which includes earnings from service charges, trust, investment management services, securities gains and other sources of fee income, was $223.2 million for the quarter. Interchange income increased 10.2 percent compared with the second quarter of 2004, and commercial credit fee income rose 25.4 percent compared with the previous year. Continued disciplined expense control resulted in noninterest expenses in the second quarter of $314.9 million, an increase of 1.0 percent compared with the previous year.

Net charge-offs were 0.21 percent of average net loans in the second quarter, declining 2 basis points compared with the first quarter of 2005. The ratio of loan loss reserves to total loans was 1.09 percent at June 30, 2005. The loan loss provision essentially matched net charge-offs in the quarter. Nonperforming loan coverage increased to 519 percent during the quarter.

Total nonperforming assets at June 30, 2005, were $90.0 million, or 0.27 percent of loans net of unearned income, foreclosed properties and repossessions, compared to $112.7 million, or 0.34 percent, in the previous quarter.
