AmSouth Reports Record First Quarter 2005 Earnings

BIRMINGHAM, Ala., April 19, 2005 – AmSouth Bancorporation (NYSE: ASO) today reported record earnings for the first quarter ended March 31, 2005, of $.50 per diluted share, compared to $.45 per diluted share reported for the first quarter of 2004. Net income for the first quarter of 2005 was $178.6 million versus $160.1 million for the same period in 2004, an increase of 11.6 percent.

This first quarter performance resulted in an increased return on average equity of 20.5 percent, a higher return on average assets of 1.44 percent, and an improved efficiency ratio of 52.7 percent.

“AmSouth’s record first quarter performance reflects strong, broad-based growth in loans and even stronger growth in deposits,” said Dowd Ritter, AmSouth’s chairman, president and chief executive officer. “We are capitalizing on disruption caused by other banks’ mergers in many of our largest markets and we expect to continue to take advantage of those opportunities.”

Net interest income was $379.7 million in the first quarter, a 5.6 percent increase compared with the same quarter in 2004. The net interest margin in the first quarter was 3.45 percent, which is an 11 basis point decline compared with the same period in 2004, but it has been stable for the past four quarters. The increase in net interest income reflects strong growth in average loans of $3.5 billion, an 11.8 percent increase over the same quarter in

1

2004. Average deposits grew by $4.2 billion, or 13.9 percent during the same period, led by the low cost category, which grew by $3.6 billion, or 17.9 percent.

Noninterest revenue, which includes earnings from service charges, trust, investment management services, securities gains and other sources of fee income, was $215.4 million for the quarter. Interchange income increased 29.9 percent compared with the first quarter of 2004, and trust income rose 5.1 percent compared with the previous year. Loan sales and a variety of other items also contributed to noninterest revenues during the quarter. Disciplined expense control resulted in noninterest expenses in the first quarter of $319.5 million, a decline of 0.9 percent compared with the previous year.

Net charge-offs were 0.23 percent of average net loans in the first quarter, declining 18 basis points compared with the fourth quarter of 2004. The ratio of loan loss reserves to total loans was 1.11 percent at March 31, 2005. The loan loss provision exceeded net charge-offs by $1.5 million in the quarter.

Total nonperforming assets at March 31, 2005, were $112.7 million, or 0.34 percent of loans net of unearned income, foreclosed properties and repossessions, compared to $110.6 million, or 0.34 percent, in the previous quarter.
