Associated 1st Quarter Earnings Per Diluted Share up 10 Percent

04/17/2003

GREEN BAY, Wis.--(BUSINESS WIRE)--April 17, 2003--Associated Banc-Corp (NASDAQ:ASBC) earned $.77 per diluted share in the quarter that ended March 31, 2003, a 10 percent increase from $.70 per diluted share for the same period in 2002.

Return on average assets was 1.58 percent in the first quarter compared to 1.54 percent in the first quarter of 2002. Return on average equity was 18.36 percent compared to 18.46 percent in the year earlier quarter.

Net interest income increased to $127 million in the first quarter, up 8.5 percent from $117 million in the year-earlier period. The company's net interest margin was 3.87 percent, down from 3.91 percent a year ago but unchanged from the previous quarter.

Total loans at the end of the first quarter 2003 were $10.3 billion, an increase of 5.3 percent compared to one year earlier. The growth occurred primarily in commercial loans, up $456 million, or 7.7 percent, and home equity loans, up $163 million, or 23.5 percent, while residential mortgage loans decreased $94 million, or 3.9 percent between the comparable first quarters. Since year-end 2002, commercial loans increased $87 million, or 5.6 percent annualized, and residential mortgage loans were down $106 million. The trend in residential mortgage loans reflects customers' continued preference for fixed rate loans in this low rate environment. Associated sells the majority of its fixed rate mortgage loans into the secondary market but continues to service these loans.

Transaction deposit accounts (demand, savings, interest-bearing demand and money market accounts) were $5.8 billion, up 8.0 percent over first quarter of last year. Time deposits were $3.3 billion at March 31, 2002, compared to $3.8 billion last year, impacted by the lower interest rate environment and scheduled maturities. Total deposits were relatively unchanged at $9.1 billion for the first quarter of 2003 compared to $9.2 billion a year ago and $9.1 billion at year-end 2002.

The provision for loan losses was $13.0 million for first quarter 2003, compared to $14.6 million for the fourth quarter last year, and $11.3 million for the comparable quarter in 2002. The ratio of the allowance for loan losses was 1.66 percent of total loans at March 31, 2003, compared to 1.58 percent and 1.48 percent at Dec. 31 and March 31, 2002, respectively.

Associated's credit quality showed modest improvement in the first quarter compared to Dec 31, 2002. Net chargeoffs for the first quarter of 2003 of $5.1 million, or 0.20 percent of average loans (annualized), were lower than net charge-offs of $7.4 million and $7.1 million in the fourth quarter of 2002 and the year-earlier quarter, respectively. Nonperforming loans were $94.7 million as of March 31, 2003, down from $99.3 million as of Dec. 31, 2002, but up from $71.7 million a year ago. Other real estate owned, which reflects property acquired by the bank due to default, was $12.9 million at March 31, 2003, bringing total nonperforming assets to 0.71 percent of total assets. The company expects asset quality to show improvement as the economy improves. However, many of the company's commercial customers continue to be challenged in the current economic environment.

Noninterest income grew to $65.2 million for the first quarter, compared to $47.4 million in the same period in 2002. Noninterest income in first quarter 2002 includes only one month's contribution from Signal Financial Corp., acquired on February 28, 2002. The continued strong activity in the mortgage and mortgage refinancing market generated $1.1 billion of mortgages for sale into the secondary market, up from $0.7 billion in the first quarter of 2002. Mortgage banking revenue of $26.1 million in the first quarter of 2003 was more than double that of the year-earlier period. Trust service fee income and retail commissions, together, declined $2.1 million as a result of continued weak stock market performance and investor uncertainty. Income in other areas posted strong gains. Service fee income from deposit accounts increased 19.5 percent year-over-year to $11.8 million, while credit card and other nondeposit fees increased 21.8 percent to $7.4 million.

Noninterest income for the first quarter of 2003 benefited from a credit card merchant processing sale and services agreement signed in March, 2003. The agreement resulted in $3.4 million of income in the first quarter of 2003, and calls for revenue sharing on new and existing merchant business over the life of the agreement.

As part of its continuing effort to provide a more complete range of financial services to its customers, Associated acquired CFG Insurance Services, Inc., one of the largest insurance agencies in the Twin Cities of Minnesota, on April 1, 2003. CFG has more than 2,500 business insurance clients in the Twin Cities, and complements Associated's existing insurance agency, Associated Insurance Management Group, Inc. When combined, the agency is expected to rank among the top 60 insurance agencies in the United States. The acquisition of CFG will further leverage Associated's banking opportunities in Minnesota, and eventually throughout Associated's markets, and will help diversify Associated's revenue stream.

Noninterest expenses remain a focus and were well controlled in the first quarter of 2003. Expenses in first quarter 2002 include only one month from Signal compared to a full quarter in 2003.

Noninterest expense grew by approximately $15.7 million, or 19.1 percent, compared to the first quarter of 2002, with more than half of the increase coming from higher mortgage servicing rights expense. While the strong mortgage refinance activity benefited mortgage banking income in the first quarter, it increased the prepayment speeds of Associated's mortgage portfolio serviced for others, a key factor behind the valuation of mortgage servicing rights. Mortgage servicing rights expense increased by $8.7 million between the comparable quarters, which includes a $7.3 million addition to the valuation allowance. The mortgage servicing asset at March 31, 2003, represents 0.54 percent of the total $5.4 billion residential mortgage portfolio serviced for others.

During the first quarter of 2003, Associated repurchased 716,500 shares of common stock, with approximately 1.4 million shares remaining under existing board repurchase authorizations.

"We are pleased that the ongoing execution of our strategies continues to produce strong results. Priorities for 2003 are to sustain our customer focus and leverage our operating structure to provide continuing value to our shareholders," Associated Banc-Corp Chairman, President and CEO Robert C. Gallagher said.

"Although our first quarter results are encouraging, our 2003 goal of 10 percent earnings per share growth is predicated on an improving economy, economic stimulus from Washington, moderate interest rate increases, and increased confidence among consumers and businesses. While we continue to look forward to these developments, expected improvements in the economy may take some time to materialize. We remain cautiously optimistic about our financial performance in 2003," Gallagher said.

Yesterday, Associated announced that its Board of Directors named Paul S. Beideman president and chief executive officer of the corporation, replacing Gallagher, 64, who is stepping down as president and CEO. Gallagher will remain chairman of the Board.

Beideman, 53, comes to Associated from Philadelphia, where he most recently served as chairman of Mellon Financial Corp.'s Mid-Atlantic Region. He has 32 years of banking experience, the last 13 in senior executive positions with Mellon. He was a member of Mellon's Senior Management Committee, and his background includes extensive experience in consumer and commercial banking. In addition, he has a wide range of experience in marketing, systems and operations, product development, and wealth management.

Associated will hold its Annual Shareholders' Meeting at 11 a.m. CDT on April 23rd, at the Meyer Theatre in Green Bay. The event will be webcast live. To view the webcast, see the information at www.associatedbank.com/AboutAssociated/InvestorRelations/.
