Report of Independent Registered Public Accounting Firm

The Plan Administrator

Associated Banc-Corp 401(k) & Employee Stock Ownership Plan:

We have audited the accompanying statements of net assets available for plan benefits of the Associated Banc-Corp 401(k) & Employee Stock Ownership Plan (the Plan) as of December 31, 2011 and 2010, and the related statements of changes in net assets available for plan benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Associated Banc-Corp 401(k) & Employee Stock Ownership Plan as of December 31, 2011 and 2010, and the changes in net assets available for plan benefits for the years then ended, in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of Schedule H, line 4i – Schedule of Assets (Held at End of Year), as of December 31, 2011, is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. This supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

(1) Description of the Plan

The following brief description of the Associated Banc-Corp 401(k) & Employee Stock Ownership Plan, formerly known as the Associated Banc-Corp 401(k) Profit Sharing & Employee Stock Ownership Plan, (the Plan) is provided for general information. The Plan contains 401(k) provisions. Participants should refer to the summary plan description for a more complete description of the Plan’s provisions.

Background

Associated Banc-Corp (the Company) has established the Associated Banc-Corp 401(k) & Employee Stock Ownership Plan, a defined contribution plan. The 401(k) provisions of the Plan provide for employee contributions complying with the provisions of Internal Revenue Code (the Code) Section 401(k) as well as employer matching contributions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Participants

Employees of the Company and its subsidiaries that have adopted the Plan are eligible to participate in the employer 401(k) contribution provisions of the Plan on January 1 of the year in which 1,000 hours of service are completed. Employees are eligible to participate in the employee 401(k) contribution portion of the Plan if they are reasonably expected to complete 1,000 hours of service annually. Otherwise, employees are eligible to participate in the Plan immediately after completing 1,000 hours of service in a Plan year.

In conjunction with the 401(k) provisions of the Plan, participants can elect to contribute an amount between 1% of their compensation and the limitations ($16,500 for 2011 and $16,500 for 2010) of Section 402(g) of the Code in increments of 1% to the Plan by means of regular payroll deductions. Participants may contribute pre-tax 401(k) contributions, Roth 401(k) contributions or a combination of both. Participants who have attained age 50 are eligible to make catch-up contributions in accordance with, and subject to the limitations ($5,500 for 2011 and $5,500 for 2010) of, Code section 414(v). Participants are also allowed to contribute amounts qualifying as rollover contributions under Section 402(c)(4) of the Code.

The Plan provides for a discretionary Company matching contribution. For 2011 and 2010 the discretionary match was equal to 100% of the first three percent deferred plus 50% of the next three percent deferred for plan participants who met the service requirements.

Vesting

Participants are 100% vested at all times in both employee and Company matching contributions under the 401(k) portion of the Plan.

The Plan was amended to discontinue the discretionary profit sharing contribution in 2007; however, participants in the plan with profit sharing balances will continue to vest according to this schedule.

Three but less than four 50 %
Four but less than five 75 %
Five or more 100 %

Forfeitures

Upon termination, the non-vested portion of Company discretionary profit sharing contributions and the earnings thereon become subject to forfeiture. At December 31, 2011 and 2010 forfeited non-vested accounts totaled $70,134 and $157,943, respectively. All forfeitures are used to reduce employer contributions in the next calendar year. During 2011, employer contributions were reduced by $157,943 from forfeited non-vested accounts.

Notes Receivable From Participants

A participant may request a loan for one or a combination of the following reasons: (a) purchase, construction or preservation/rehabilitation of a participant-owned principal residence, (b) post-secondary education expenses for the participant, their spouse or their dependents, (c) medical expenses incurred by the participant or the participant’s immediate family, (d) funeral expenses for the participant’s deceased parent, spouse, children or dependents, or (e) expenses for the repair of damage to the participant’s principal residence that would qualify for casualty loss deduction.

Loans are limited to the lesser of (1) $50,000, reduced by the excess of the highest outstanding balance of loans from the Plan during the one-year period ending on the day before the date on which such loan was made over the outstanding balance of loans from the Plan on the date on which such loan was made or (2) 50% of the vested benefit of the participant’s account balance. Participant loans will not be granted for less than $1,000.

A commercially reasonable fixed rate of interest will be assessed on the loan with the current rate set at the prime rate plus 2% offered by Associated Bank, N.A. Interest rates range from 3.25% to 9.00%. The loan will provide bi-weekly payments under a level amortization schedule of not greater than 5 years or 15 years if a loan is used to acquire a principal residence. The plan may also hold grandfathered or inherited loans from merged plans with maturity dates extended beyond the 15 years allowed by the Plan document.

Participant Accounts

The Plan is a defined contribution plan under which a separate individual account is established for each participant. Plan investments are valued daily. Due to daily valuation, contributions are allocated to participant accounts upon receipt, and income and changes in asset values are immediately allocated to the participants’ accounts. Under a daily valued plan, participants can verify account balances daily utilizing the VRU (Voice Response Unit) or Internet access.

Distributions

Distributions are made in the form of lump-sum payments, payments over a period in monthly, quarterly, semi-annual or annual installments and other payment forms allowed by the Plan document.

In the event of termination, participants become fully vested to the extent of the balance in their account, including investment income through the termination date.

(2 ) Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared on the accrual basis of accounting and present the net assets available for plan benefits and changes in those net assets in accordance with U.S. generally accepted accounting principles.

New Accounting Pronouncements

In May 2011, the FASB issued Accounting Standards Update 2011-04, Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS (ASU 2011-04). ASU 2011-04 amended ASC 820, Fair Value Measurements and Disclosures, to converge the fair value measurement guidance in GAAP and International Financial Reporting Standards. Some of the amendments clarify the application of existing fair value measurement requirements, while other amendments change a particular principle in ASC 820. In addition, ASU 2011-04 requires additional fair value disclosures. The amendments are to be applied prospectively and are effective for annual periods beginning after December 15, 2011. Plan management is currently evaluating the effect that the provisions of ASU 2011-04 will have on the Plan’s financial statements.

In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures, which required entities to make new disclosures about recurring and nonrecurring fair value measurements including significant transfers in and out of Level 1 and 2 categories and provide information on purchases, sales, issuances and settlements on a gross basis in the reconciliation of Level 3 measurements. ASU No. 2010-06 also clarifies

10

Table of Contents

ASSOCIATED BANC-CORP

401(k) & EMPLOYEE STOCK OWNERSHIP PLAN

NOTES TO FINANCIAL STATEMENTS

December 31, 2011 and 2010

existing fair value disclosures. ASU No. 2010-06 is effective for periods beginning after December 15, 2009, except for the requirement to provide Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which will be effective for fiscal years beginning after December 15, 2010. Refer to Footnote (7) for discussion of fair value measurements and relevant ASU No. 2010-06 disclosures.

The significant accounting policies of the Plan are as follows:

Investments and Income Recognition

Investment securities are recorded at fair value. Fair value of common stock and mutual funds is based on quoted market prices. The investments in units of the common/collective funds are carried at the net asset value (NAV), which is the value at which units in the funds can be withdrawn and approximates fair value as a practical expedient. The money market account is stated at cost, which approximates fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Footnote (7) for discussion of fair value measurements.

Cash surrender values are provided by the underlying insurance providers at year end and also upon individual policy surrender. As such, these holdings are valued at the year end cash surrender values, which approximates fair value. Upon death of the participant, death benefits are paid directly to the beneficiary from the insurance provider and not by the Plan. Any cash surrender value upon termination of a life insurance policy is paid directly to terminated participant or to the Plan for active participants.

Plan assets are held by the trustee. Net appreciation includes realized gains and losses on investments purchased and sold and changes in appreciation for the period. Purchases and sales of securities are recorded on a trade-date basis. Realized gains and losses on the sale of investments are determined through the use of moving average basis. The Plan records interest income on the accrual basis and dividends on the ex-dividend date.

The Plan’s investments are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the values of investments, it is at least reasonably possible that changes in risks in the near term could materially affect participant account balances and the amounts reported in the financial statements of the Plan.

Notes Receivable from Participants

Notes Receivable from Participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan document.

Payment of Benefits

Benefits are recorded when paid.

Operating Expenses

Loan and distribution recordkeeping fees are paid by the respective participant. All other expenses of maintaining the plan are paid by the Company.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Plan Administrator to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from these estimates.

(6) Income Taxes

The Plan Administrator has received a favorable tax determination letter, dated February 3, 2006, from the Internal Revenue Service indicating that the Plan qualifies under the

NOTES TO FINANCIAL STATEMENTS

provisions of Section 401(a) of the Code, and the related trust is, therefore, exempt from tax under Section 501(a). Therefore, a provision for income taxes has not been included in the Plan’s financial statements. The Plan has been amended since receiving the determination letter. However, in the opinion of the Plan Administrator, the Plan and its underlying trust have operated within the terms of the Plan and remain qualified under the applicable provisions of the Code.

Participants in the Plan are not subject to federal income taxes until they receive a distribution from the Plan.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2011, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2009.

(7) Fair Value Measurements

ASC Topic 820-10, Fair Value Measurements and Disclosures, applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard amends numerous accounting pronouncements but does not require any new fair value measurements of reported balances. The standard also emphasizes that fair value (i.e., the price that would be received in an orderly transaction that is not a forced liquidation or distressed sales at the measurement date), among other things, is based on exit price versus entry price, should include assumptions about risk such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. When considering the assumptions that market participants would use in pricing the asset or liability, this accounting standard establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The fair value hierarchy prioritizes inputs used to measure fair value into three broad levels.

Level 1 inputs - utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Plan has the ability to access.

Level 2 inputs - inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.

Level 3 inputs - unobservable inputs for the asset or liability, which are typically based on the entity’s own assumptions, as there is little, if any, related market activity.

There have been no changes in the methodologies used at December 31, 2011 and 2010 and there have been no transfers between fair value levels.

The following table summarizes the Plan’s investments at December 31, 2011, based on the inputs used to value them:
