Associated announces 2nd quarter earnings per diluted share of $.60

     GREEN BAY, Wis. — July 21, 2005 — Associated Banc-Corp (NASDAQ: ASBC) earned $.60 per diluted share in the quarter ended June 30, 2005, compared to $.59 per diluted share for the first quarter of 2005, and $.58 per diluted share for second quarter 2004. For the six months ended June 30, 2005, diluted earnings per share were $1.19, up 7.2 percent from $1.11 per diluted share in the same period in 2004.

     For second quarter 2005, return on average assets (ROAA) was 1.52 percent, return on average equity (ROAE) was 15.41 percent and book value per share was $15.77, compared to 1.54 percent, 15.52 percent, and $15.61, respectively, for the first quarter of 2005. Comparatively, for second quarter 2004 ROAA was 1.67 percent, ROAE was 18.87 percent, and book value per share was $12.53. For the first half of 2005, ROAA was 1.53 percent and ROAE was 15.47 percent, compared to 1.62 percent and 18.12 percent, respectively, for the six months ended June 30, 2004.

     “Our second quarter results reflect solid loan growth, core fee income growth, and asset quality that remains strong. We are aggressively managing our costs in a challenging rate and competitive pricing environment,” Associated President and CEO Paul Beideman said.

     Associated’s acquisition of First Federal Capital Corp on Oct. 29, 2004 affects comparisons between the years, as 2005 results include the balance sheet and operations of the $4 billion thrift, while the comparable 2004 periods do not. First Federal’s operations were successfully integrated onto Associated’s systems in February 2005. Additionally, the April 1, 2004 acquisition of Jabas Group, Inc., an employee benefits firm, affects the comparison of retail commission income and noninterest expenses between the year-to-date periods, as only three months of Jabas are included in the first half of 2004. Finally, the changes in net mortgage

banking income impact the comparison of noninterest income between prior periods, particularly from movements in the value of the mortgage servicing rights (MSR) asset.

     Net income was $78.0 million for the second quarter of 2005. This compares to $77.5 million for the quarter ended March 31, 2005, and $64.5 million for the second quarter of 2004. On a year-to-date basis, net income was $155.5 million, up 25 percent from $124.1 million for the comparable period of 2004.

     Associated’s net interest income for the second quarter of 2005 was $166.7 million, compared to $165.9 million for first quarter 2005, and $131.9 million in the year-earlier quarter. For the first half of 2005, net interest income was $332.6 million, up from $261.0 million for the comparable year-to-date period of 2004. The increase is due predominantly to higher average balance sheet volumes.

     Net interest margin for the second quarter was 3.63 percent, compared to 3.68 percent for first quarter 2005 and 3.80 percent for second quarter 2004. On a year-to-date basis, the net interest margin was 3.65 percent, versus 3.80 percent for the comparable period last year. The trend in the net interest margin is primarily from the impact of the continued flattening of the yield curve, and competitive pricing pressures.

     Period end loans at June 30, 2005 were $14.1 billion, compared to $13.9 billion at March 31, 2005 (up 4 percent on an annualized basis), with loan growth primarily in commercial (up 7 percent annualized) and home equity (up 14 percent annualized). Quarterly average loan balances, a key driver to net interest income, were $14.1 billion for second quarter 2005, up 3 percent annualized compared to first quarter 2005, and up 32 percent between second quarter periods, including the First Federal acquisition.

     Period end deposits at June 30, 2005 were $12.1 billion, down slightly from $12.2 billion at March 31, 2005, primarily from decreases in interest-bearing transaction accounts and other time deposits offset partly by increases in noninterest-bearing demand deposits and institutional CDs. Deposits were up 26 percent over a year earlier, including the acquisition of First Federal. On average, deposits were $12.1 billion for second quarter 2005, compared to $12.4 billion for first quarter (down 9 percent annualized). Between the comparable second quarters, average deposits were up 24 percent.

     “The decline in deposits since March 31, 2005, is primarily from seasonal movements in municipal deposits and lower non-brokered time deposits,” Beideman said. “We are encouraged by the growth in our demand deposits, increasing over 17 percent on an annualized basis since March 31, and by our deposit growth strategies for the second half of 2005.”

     Asset quality remained steady, with second quarter net charge-offs of $3.6 million, compared to net charge-offs of $2.2 million for first quarter 2005 and $5.6 million for second quarter 2004. For the first half of 2005, net charge-offs were $5.7 million (0.08 percent of average loans), versus $10.7 million (0.20 percent of average loans) for the first half of 2004. The provision for loan losses approximated the related net charge-off levels for each of the comparative quarterly and year-to-date periods. Nonperforming loans at June 30, 2005 were $112.5 million, representing 0.80 percent of loans, compared to $102.9 million or 0.74 percent of loans at March 31, 2005, and 0.81 percent of loans at June 30, 2004. The $9.6 million increase in nonperforming loans since March 31 was predominantly attributable to the addition of one large commercial real estate credit.

     At June 30, 2005, the allowance for loan losses was $190.0 million. The allowance for loan losses to total loans was 1.35 percent and covered 169 percent of nonperforming loans at June 30, 2005, compared to 1.36 percent and 184 percent, respectively, at the end of first quarter 2005, and 1.69 percent and 207 percent, respectively, at June 30, 2004.

     Noninterest income was $68.4 million for second quarter 2005, compared to $71.4 million for first quarter 2005, and $57.9 million for second quarter 2004, with year-to-date noninterest income at $139.8 million or 34 percent higher than the six-month period in 2004. Changes in net mortgage banking income (gross mortgage banking income less MSR expense), particularly from movements in the value of the MSR asset, impact the comparison of noninterest income between the various periods. Excluding net mortgage banking income, noninterest income was $66.1 million for second quarter 2005, up 7 percent over $61.5 million for first quarter 2005, and up 42 percent over $46.5 million for second quarter 2004. For the six months ended June 30, 2005, noninterest income excluding net mortgage banking income was $127.5 million, or 41 percent higher than $90.4 million for the first half of 2004.

     Net mortgage banking income was $2.4 million for second quarter 2005, down $7.5 million from first quarter 2005, and down $9.0 million compared to second quarter 2004. On a year-to-date basis, net mortgage banking income was $12.3 million for 2005, down $1.4 million compared to last year.

     Quarterly MSR expense was impacted primarily by changes in estimated prepayment speeds and related movements in the estimated fair value of the MSR asset. MSR expense of $8.3 million (including a valuation reserve addition of $2.5 million) for second quarter 2005 was $6.5 million higher than first quarter 2005 (which included a valuation recovery of $4.0 million), and was $10.7 million higher than second quarter 2004 (which included a valuation recovery of

$6.7 million). At June 30, 2005, the net MSR asset was $74.1 million, representing 78 basis points of the $9.48 billion portfolio serviced for others, compared to 82 basis points and 81 basis points at March 31, 2005, and June 30, 2004, respectively.

     Quarterly service charges on deposit accounts of $22.2 million were up 19 percent over first quarter 2005 and up 69 percent over second quarter 2004. Trust service fees of $9.0 million for second quarter 2005 grew 8 percent and 11 percent over first quarter 2005 and second quarter 2004, respectively. Quarterly retail commissions of $15.4 million experienced growth of 5 percent over first quarter 2005 and 17 percent over second quarter 2004.

     Noninterest expense was $116.3 million for second quarter 2005, down $4.9 million (4 percent) versus first quarter 2005, and up $24.3 million (27 percent) over second quarter last year. On a year-to-date basis, noninterest expense was $237.6 million, or 33 percent higher than the comparable six-month period last year.

     Personnel expense was $66.9 million in second quarter 2005, down $6.1 million (8 percent) from first quarter 2005. This was largely due to reduced personnel costs associated with a 5 percent decline in average full time equivalent employees, notably attributable to First Federal cost savings. Personnel expense for second quarter was up $13.3 million (25 percent) over second quarter 2004 which did not include First Federal. All other noninterest expenses combined were $49.4 million for second quarter 2005, up 2 percent over $48.3 million for first quarter 2005.

     The efficiency ratio remained low at under 50 percent for all quarter and year-to-date periods presented.

     “As evidenced by our expense run rates and efficiency ratio, we were successful in achieving our planned cost savings associated with the First Federal acquisition.” Beideman said. “We now look forward to continuing the implementation of our strategic priorities and realizing the potential in our enhanced distribution system.”

     “Given current trends in our business, continued loan growth, and our demonstrated cost control, coupled with a steepening of the yield curve, we anticipate we can meet consensus earnings estimates for 2005,” Beideman added. “However, intense competition for deposits and the challenging revenue environment could negatively impact these results.”

     Aided by an accelerated share buyback in May 2005, Associated repurchased 2.1 million shares of its common stock in the second quarter under all repurchase authorizations, at an average price of $33.10 per share, bringing year-to-date common stock repurchases to 2.5 million

shares at a $33.05 average price per share. Also, during the second quarter, the company paid a dividend of 27 cents per share, up 8 percent from the year-earlier dividend.

     Associated’s pending acquisition of State Financial Services Corp (Nasdaq: SFSW), a $1.5 billion financial services company based in Milwaukee, is scheduled for vote by State Financial shareholders on August 24, 2005.
