Associated Banc-Corp Reports First Quarter 2011 Earnings

Net Income to Shareholders of $15.4 Million, or $0.09 per Share

GREEN BAY, Wis. — April 21, 2011 — Associated Banc-Corp (NASDAQ: ASBC) today reported net income to common shareholders of $15.4 million, or $0.09 per common share, for the quarter ended March 31, 2011. This compares to net income to common shareholders of $6.6 million, or $0.04 per common share, for the quarter ended December 31, 2010.

HIGHLIGHTS

•		Pre-tax income improved $25.0 million and net income improved $8.8 million over prior quarter

	•		Nonaccrual loans declined $86 million, or 15% from the prior quarter

	•		Potential problem loans down 5.4% from prior quarter
	•		Net charge-offs were $53 million, down from $108 million the prior quarter

•		Net interest margin expanded for the second consecutive quarter, increasing 19 basis points to 3.32%
•		Capital ratios remain very strong with a Tier 1 common ratio of 12.65%
•		Transferred $61 million of non-core consumer finance installment loans to held for sale, resulting in a $10 million charge-off in the quarter; sale is anticipated to close in the second quarter of 2011
•		Subsequent to quarter end, $262.5 million, or half, of Troubled Asset Relief Program (TARP) Preferred Stock was repurchased

“We are pleased to report our fifth consecutive quarter of improving profitability.

Key Credit Metrics

Nonaccrual loans declined to $488 million at March 31, 2011, down 15% from $574 million at December 31, 2010. Previous quarterly improvements in nonaccrual loans were largely driven by bulk loan sales; however, the improvement in nonaccrual loans this quarter was driven by organic portfolio improvements, including a lower level of inflows to nonaccrual and problem loan categories.

Other key credit metrics also continued to improve during the quarter. Loans 30-89 days past due totaled $106 million at March 31, 2011, down 12% from $120 million at December 31, 2010. Potential problem loans continued to decline to $912 million at March 31, 2011, down $52 million, or 5.4% from $964 million at December 31, 2010.

Net charge-offs were $53 million for the quarter, down 51% from $108 million during the fourth quarter of 2010. Commercial loan charge-offs declined by $64 million. Consumer loan charge-offs which increased $9 million, includes a $10 million write-off related to the transfer of $61 million of non-core consumer finance installment loans to held for sale during the quarter.

The provision for loan losses was $31 million for the first quarter of 2011, down from $63 million for the prior quarter. The Company’s allowance for loan losses was $454 million, or 3.59% of total loans, at March 31, 2011. This compares to an allowance for loan losses of $477 million, or 3.78%, of total loans at December 31, 2010. The allowance’s coverage of nonaccrual loans improved to 93% at the end of the first quarter of 2011, compared to 83% at the end of the fourth quarter of 2010.

Net Interest Income

Net interest income increased $2.9 million, to $153.7 million, up 2% from the fourth quarter of 2010. The increase was primarily driven by growth in mortgage loan interest income, lower deposit costs, lower wholesale funding costs, and increased income from investments. These improvements were partially offset by lower interest income on commercial real estate loans and consumer loans.

During the quarter, the Company continued to realize the benefits of the deposit and investment strategies we began to implement in the fourth quarter of 2010.

Net interest margin for the quarter ended March 31, 2011, was 3.32%, up 19 basis points from 3.13% for the fourth quarter of 2010. While we expect the margin earned from banking activities will continue to trend higher as the Company grows loans and further optimizes its funding mix and deposit pricing; recent holding company financing, which partially funded our TARP repayment, will more than offset this benefit going forward. Although the net effect of the financed repayment of TARP will be accretive to earnings per share, net interest income and margin will be negatively impacted in future quarters.

Loans and Deposits

Total loans were $12.7 billion at March 31, 2011, up 1%, from $12.6 billion at December 31, 2010, and average loans grew at an annualized rate of 2.8%.

For the first quarter, the residential mortgage segment of the portfolio grew 8% to $2.5 billion, and the home equity segment of the portfolio was up 2% to $2.6 billion from the prior quarter. The increases in the residential mortgage and home equity segment of the portfolio for the quarter were offset by declines in most other loan categories as we continued to rebalance our risk appetite. Commercial mortgage and construction portfolios totaled $3.9 billion at the end of the quarter, down 4% on annualized basis, from the prior period as we continued to pare our exposures. In contrast, our average C&I lending book, excluding the impact of loan sales and resolutions, expanded on a consecutive quarter basis.

Total interest bearing liabilities declined $569 million, or 4%, as the Company continued to optimize its funding base. Wholesale funding, network and brokered deposits continued to be managed downward, while customer term and sweep repurchase balances continued to grow. At March 31, 2011, all of the Company’s repurchase liabilities totaling $1.9 billion were with customers.

Noninterest Income and Expense

Noninterest income for the quarter ended March 31, 2011, was $72 million, down $13 million compared to $85 million for the fourth quarter of 2010, primarily due to weaker mortgage banking income. Core fee-based revenue of $61 million for the quarter ended March 31, 2011, compared to $60 million for the quarter ended December 31, 2010, as increases in retail commission and trust fees exceeded a $1 million decrease in deposit-related fees.

Mortgage loans originated for sale were $290 million for the quarter ended March 31, 2011, down from $630 million the prior quarter, as a generally higher interest rate environment resulted in lower refinancing activity during the quarter. Net mortgage banking income for the quarter totaled $2 million, down 86% from $13 million for the fourth quarter of 2010. First quarter mortgage banking results included a $0.2 million valuation charge related to mortgage servicing rights compared to a $3 million valuation recovery for the fourth quarter of 2010.

Total noninterest expense for the quarter ended March 31, 2011, was $164 million, down $3 million, or 2%, from $167 million for the quarter ended December 31, 2010. The decrease in total noninterest expense over the prior quarter was primarily due to declines in foreclosure/OREO and FDIC expenses. These declines were partially offset by an increase in personnel and occupancy expenses.

The Company reported income tax expense of $8 million for the first quarter of 2011. This compares to an $8 million tax benefit for the prior quarter, which included a $5 million benefit related to the resolution of certain tax matters, which occurred during the quarter.

“We are pleased with the progress we have made and continue to be highly positive about the future of our company. Our pro forma capital ratios following the notes offering and partial repurchase of the TARP preferred stock continue to exceed the requirements of our regulators and standards for well-capitalized banks. This strong capital position provides us with flexibility as we continue to execute our strategic plans for growth,” said Flynn. “We remain confident we will achieve our goal of repaying all of the TARP funds in 2011 and will do so in the most shareholder-friendly manner possible.”
