Report of Independent Registered Public Accounting Firm
Pension Review Committee of the Board of Directors
Huntington Bancshares Incorporated
We have audited the accompanying statements of net assets available for benefits of the Huntington Investment and Tax Savings Plan (the “Plan”) as of December 31, 2005 and 2004, and the related statements of changes in net assets available for 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 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. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2005 and 2004, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America.
Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2005, 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 schedule is the responsibility of the Plan’s management. This schedule has been subjected to the auditing procedures applied in our audit of the basic 2005 financial statements and, in our opinion, is fairly stated in all material respects when considered in relation to the basic 2005 financial statements taken as a whole.

HUNTINGTON INVESTMENT AND TAX SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
December 31, 2005
Note 1 – Description of the Plan
The Huntington Investment and Tax Savings Plan (the “Plan”) is a defined contribution plan that was initially adopted by the Board of Directors of Huntington Bancshares Incorporated (“Huntington”) on September 29, 1977, to be effective January 1, 1978 to provide benefits to eligible employees of Huntington, as defined in the Plan document. Plan participants should refer to the Plan document for a more complete description of the Plan’s provisions. On December 13, 2000, Huntington’s common stock held in accounts of participants who elected to have all or a portion of their accounts invested in Huntington’s common stock were designated an Employee Stock Ownership Plan (ESOP). The ESOP forms a portion of the Plan.
Amendments – From time to time, the Plan has been amended and restated. The current restatement is effective January 1, 1997, unless the restated document provides another effective date. A First Amendment to the Plan was adopted October 16, 2002, to bring the Plan into compliance with the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA) and to effect other changes. EGTRRA changes were generally effective January 1, 2002.
Funding and Vesting – Eligible employees may enroll on the first day of the month following six months of employment and attainment of age 21. Participants may elect to make pre-tax contributions of up to 25% of their eligible compensation. Huntington will make a matching contribution equal to 100% on the first 3% of participant elective deferrals and 50% on the next 2% of participant elective deferrals. Participant and employer contributions are fully vested at all times.
Investment Options – Plan participants are permitted to direct pre-tax elective deferrals and employer matching contributions to any combination of 20 investment options, including Huntington common stock and a variety of investment funds. Huntington has the sole discretion to determine or change the number and nature of investment options in the Plan. An active participant may change or suspend pre-tax elective deferrals pursuant to the terms set forth in the Plan document.
Risks and Uncertainties – The Plan utilizes various investment instruments, including mutual funds and common stock. In general, investment securities are exposed to various risks such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes will materially affect the amounts in the financial statements.
Administration – The Plan administrator is Huntington. Portions of Plan administration have been delegated by the Plan administrator to a committee of employees appointed by the Board of Directors of Huntington. The Plan administrator believes that the Plan is currently designed and operated in compliance with the applicable requirements of the Internal Revenue Code (the Code) and the provisions of ERISA, as amended.

Participants are charged a fixed amount for administration of the Plan. All other administrative fees are paid from the general assets of Huntington.
Contributions – Employee and Employer contributions to participants’ accounts in the Plan are invested pursuant to the participants’ investment direction elections on file at the time the contributions are allocated to the participants’ accounts. Plan assets consist of shares of Huntington common stock and mutual funds and are held by the trust division of The Huntington National Bank (the Plan Trustee), a wholly-owned subsidiary of Huntington. The Plan Trustee purchases and sells shares of Huntington common stock on the open market at market prices. Additionally, the Plan Trustee may directly purchase from, and sell to, Huntington, at market prices, shares of Huntington common stock. The Plan Trustee purchases and redeems shares of mutual funds in accordance with rules of the mutual funds.
Benefit Distributions and Other Withdrawals – A participant may request that the portion of his or her account that is invested in Huntington common stock be distributed in shares of Huntington common stock with cash paid in lieu of any fractional shares. All other distributions from the Plan are paid in cash.
Distributions and withdrawals are reported at fair value and recorded by the Plan when payments are made.
Participants are permitted to take distributions and withdrawals from their accounts in the Plan under the circumstances set forth in the Plan document. Generally, participants may request withdrawal of funds in their account attributable to: (i) rollover contributions; (ii) after-tax contributions; and (iii) pre-April 1, 1998, Employer contributions. Employee pre-tax elective deferrals and post April 1, 1998 Employer matching contributions are subject to special withdrawal rules and generally may not be withdrawn from the Plan prior to a participant’s death, disability, termination of employment, or attainment of age 59 1/2. Certain distributions of Employee pre-tax deferrals may be made, however, in the event a participant requests a distribution due to financial hardship as defined by the Plan. Participants should refer to the Summary Plan Description for a complete summary of the Plan provisions. Participants may withdraw up to 100% of their account balances in the Plan for any reason after they have reached age 59 1/2.
Plan participants have the option of reinvesting cash dividends paid on Huntington common stock or having dividends paid in cash.
Plan Termination – Huntington intends to continue the Plan indefinitely for the benefit of its participants; however, it reserves the right to terminate or modify the Plan at any time by resolution of its Board of Directors and subject to the provisions of ERISA. In the event the Plan is terminated in the future, participants would become fully vested in their accounts.
Certain prior period amounts have been reclassified to conform to the current year’s presentation.
Note 2 – Significant Accounting Policies
Basis of Presentation – The financial statements of the Plan are presented on the accrual basis and are prepared in accordance with accounting principles generally accepted in the United States (GAAP).

9


 

Cash Dividends and Interest Income – Dividends are recognized as of their record date. Interest is recorded on an accrual basis when earned.
Valuation of Investments – Investments are accounted for at cost on the trade-date and are reported in the Statement of Net Assets Available for Benefits at fair value. The investment in Huntington common stock is valued using the year-end closing price as determined by NASDAQ. Mutual funds are stated at fair value as determined by quoted market prices, which represents the net asset value of shares held by the Plan at year end.
Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts of assets and liabilities, and changes therein, reported in the financial statements. Actual results could differ from those estimates.

Note 5 – Income Taxes
The Plan obtained its latest determination letter dated December 13, 2002, in which the Internal Revenue Service stated the Plan, as then designed, was qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. Huntington believes the Plan is being operated in compliance with applicable requirements of the Code and related state statutes, and that the trust, which forms a part of the Plan, is qualified and exempt from federal income and state franchise taxes.
Note 6 – Terminated Participants
There were no amounts included in net assets available for benefits allocated to individuals who have withdrawn from the Plan at December 31, 2005 and 2004.
