GREEN BAY, Wis. — January 22, 2009 — Associated Banc-Corp (NASDAQ: ASBC) reported net income available to common shareholders of $165 million, or $1.29 per common share for 2008. Comparatively, net income was $286 million, or $2.23 per common share for 2007.

Net income available to common shareholders was $14 million, or $0.11 per common share for fourth quarter 2008, compared to $38 million ($0.30 per common share) for third quarter 2008 and $65 million ($0.51 per common share) for fourth quarter 2007.

Fourth quarter 2008 results included several nonrecurring items or other charges. Other-than-temporary valuation losses on investments were $35 million or $0.18 per common share after tax. In combination, a $7 million valuation reserve expense related to the fair value of mortgage servicing rights, a $3 million loss on an alleged customer fraud, and a $3 million write down on a foreclosed property reduced diluted earnings per common share by $0.07.

A single bond security is responsible for $31 million of the fourth quarter other-than-temporary marks, and has a remaining carrying value of $33 million at Dec. 31. The bond is comprised of large fixed-rate, 30-year amortizing mortgages with reasonably strong loan-to-value ratios and weighted average credit scores. In consideration of a significant fourth quarter decline in the market value of this bond and the business and economic environment, other-than-temporary impairment was recorded. Of the remaining $3.7 billion of mortgage-related securities held at year-end 2008, $3.6 billion are agency insured, and the vast majority of the remainder are seasoned. As a result, further exposure to other-than-temporary impairment is not expected to be significant.

In November 2008, Associated sold $525 million of senior preferred stock, bearing a 5% dividend for the first 5 years and 9% thereafter, and related common stock warrants, to the U.S. Department of the Treasury under the federal government’s voluntary Capital Purchase Program. As a result, stockholders’ equity at December 31, 2008, included $508 million attributable to the senior preferred stock net of the preferred stock discount. The tangible capital ratio grew to 8.23% at year end 2008, compared to 6.50% at Sept. 30 and 6.59% a year ago. Finally, the senior preferred stock dividends and discount amortization that began in the fourth quarter reduced net income available to common shareholders by $3 million, or $0.03 per common share.

Since the infusion of capital over $1.5 billion of credit has been originated or committed to be extended to new and existing customers.

During the fourth quarter of 2008, Associated invested in guaranteed government agency mortgage-related securities in support of the mortgage markets. Thus, since Sept. 30, total assets and investment securities were each up $1.7 billion.

For fourth quarter 2008, net interest income was $192 million, $25 million (15 percent) higher than third quarter, with the net interest margin improving 40 basis to 3.88 percent.

Average loans were $16.3 billion for fourth quarter 2008, up $0.1 billion (2 percent annualized) over the third quarter of 2008, led by consumer-based loan growth, while commercial loan growth was offset by workouts and charge offs. Average deposits for fourth quarter were $14.4 billion, up $0.7 billion over third quarter 2008, primarily attributable to higher network transaction deposits and brokered CDs. At Dec. 31, deposits were $15.2 billion, up $0.9 billion over Sept. 30, with growth in nearly all categories, especially demand deposits (up $0.3 million or 11 percent) and money markets (up $0.3 million or 7 percent).

The provision for loan losses was $65 million and net charge offs were $46 million for fourth quarter 2008, compared to $55 million and $38 million, respectively, for third quarter 2008. During this quarter, nonperforming loans increased $36 million to $341 million at year-end 2008 (representing 2.09 percent of loans), compared to nonperforming loans of $163 million (or 1.05 percent of loans) at year-end 2007. The allowance for loan losses to total loans ratio increased to 1.63 percent at Dec. 31, 2008, compared to 1.51 percent at Sept. 30, 2008, and 1.29 percent at year-end 2007.

Core fee-based revenues for fourth quarter 2008 were $67 million, up $3 million or 5 percent over the fourth quarter of last year.

For the fourth quarter 2008 mortgage banking incurred a $1 million net loss, principally from a $7 million valuation charge related to mortgage servicing rights fair value. Comparatively, net mortgage banking income was $0.5 million (including a $1.4 million valuation charge) for fourth quarter 2007, and $4 million (including a favorable $1 million valuation recovery) for third quarter 2008. Mortgage applications increased 200% in December of 2008 over November, of which the majority will close in the first quarter of 2009.

Fourth quarter 2008 noninterest expense was $149 million, up $12 million or 9 percent over third quarter 2008. Previously noted items (severance, fraud matter and foreclosed property write down) accounted for $7 million of the increase, with the remainder largely due to elevated foreclosure/collection costs, increased legal and consultant expense, and higher weather-related occupancy costs. Compared to the fourth quarter last year, noninterest expense was up 6 percent. The efficiency ratio improved to 52.41 percent for 2008, compared to 53.92 percent for 2007, while for the fourth and third quarters of 2008, the efficiency ratio was 53.87 percent and 52.18 percent, respectively.

During the fourth quarter, Associated paid a dividend of 32 cents per common share, bringing the 2008 dividend per common share to $1.27, up 4 percent from 2007.
