Basis of Presentation Use of Pro Forma data - --------------------- This presentation contains Pro Forma financial measures where management believes it to be helpful in understanding how the proposed merger with Sky Financial Group will impact Huntington's results of operations or financial position. The data represent actual reported information as of September 30, 2006 for both organizations, combined arithmetically, with no adjustments for purchase accounting made, unless otherwise noted. The data for Sky Financial Group also include Union Federal Bank reported information on a similar pro forma basis, as this transaction was completed by Sky Financial Group subsequent to September 30, 2006. Use of non-GAAP financial measures - ---------------------------------- This presentation contains GAAP financial measures and non-GAAP financial measures where management believes it to be helpful in understanding Huntington's results of operations or financial position. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the current quarter earnings press release, this presentation, or in the Quarterly Financial Review supplement to the current Earnings Press Release, which can be found on Huntington's website at huntington-ir.com. Annualized data - --------------- Certain returns, yields, performance ratios, or growth rates for a quarter are "annualized" in this presentation to represent an annual time period. This is done for analytical and decision -making purposes to better discern underlying performance trends when compared to full-year or year-over-year amounts. For example, loan growth rates are most often expressed in terms of an annual rate like 8%. As such, a 2% growth rate for a quarter would represent an annualized 8% growth rate. Fully taxable equivalent interest income and net interest margin - ---------------------------------------------------------------- Income from tax-exempt earnings assets is increased by an amount equivalent to the taxes that would have been paid if this income had been taxable at statutory rates. This adjustment puts all earning assets, most notably tax-exempt municipal securities and certain lease assets, on a common basis that facilitates comparison of results to results of competitors. Earnings per share equivalent data - ---------------------------------- Significant and/or one-time income or expense items may be expressed on a per common share basis. This is done for analytical and decision -making purposes to better discern underlying trends in total corporate earnings per share performance excluding the impact of such items. Investors may also find this information helpful in their evaluation of the company's financial performance against published earnings per share consensus amounts, which typically exclude the impact of significant and/or one-time items. Earnings per share equivalents are usually calculated by applying a 35% effective tax rate to a pre-tax amount to derive an after-tax amount which is divided by the average shares outstanding during the respective reporting period. Occasionally, when the item involves special tax treatment, the after-tax amount is separately disclosed, with this then being the amount used to calculate the earnings per share equivalent. Rounding - -------- Please note that columns of data in the following slides may not add due to rounding. NM or nm - -------- Percent changes of 100% or more are shown as "nm" or "not meaningful" . Such large percent changes typically reflect the impact of one-time items within the measured periods. Since the primary purpose of showing a percent change is for discerning underlying performance trends, such large percent changes are "not meaningful" for this purpose. 18

Forward Looking Statements This presentation contains certain forward -looking statements, including certain plans, expectations, goals, and projections, and including statements about the benefits of the merger between Huntington and Sky Financial Group, which are subject to numerous assumptions, risks, and uncertainties. Actual results could differ materially from those contained or implied by such statements for a variety of factors including: the businesses of Huntington and Sky Financial Group may not be integrated successfully or such integration may take longer to accomplish than expected; the expected cost savings and any revenue synergies from the merger may not be fully realized within the expected timeframes; disruption from the merger may make it more difficult to maintain relationships with clients, associates, or suppliers; the required governmental approvals of the merger may not be obtained on the proposed terms and schedule; Huntington and/or Sky Financial Group's stockholders may not approve the merger; changes in economic conditions; movements in interest rates; competitive pressures on product pricing and services; success and timing of other business strategies; the nature, extent, and timing of governmental actions and reforms; and extended disruption of vital infrastructure; and other factors described in Huntington's 2005 Annual Report on Form 10-K, Sky Financial Group's 2005 Annual Report on Form 10-K, and documents subsequently filed by Huntington and Sky Financial Group with the Securities and Exchange Commission.
