Use of Non-GAAP Financial Measures This document 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 this document, the earnings press release, or the Form 8-K related to this document, all of which can be found on the “Investor Relations” section of Huntington’s website at www.huntington.com. Annualized Data Certain returns, yields, performance ratios, or quarterly growth rates are presented on an “annualized” basis. 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 and deposit growth rates, as well as net charge-off percentages, 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 earning 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 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 mean estimate amounts, which typically exclude the impact of Significant Items. Earnings per share equivalents are usually calculated by applying an 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 disclosed separately, with this then being the amount used to calculate the earnings per share equivalent. Rounding Please note that columns of data in this document may not add due to rounding. Basis of Presentation 31 Do we consolidate this and next slide?

Significant Items From time to time, revenue, expenses, or taxes are impacted by items judged by Management to be outside of ordinary banking activities and/or by items that, while they may be associated with ordinary banking activities, are so unusually large that their outsized impact is believed by Management at that time to be infrequent or short term in nature. We refer to such items as “Significant Items”. Most often, these Significant Items result from factors originating outside the company – e.g., regulatory actions/assessments, windfall gains, changes in accounting principles, one-time tax assessments/refunds, litigation actions, etc. In other cases they may result from Management decisions associated with significant corporate actions out of the ordinary course of business – e.g., merger/restructuring charges, recapitalization actions, goodwill impairment, etc. Even though certain revenue and expense items are naturally subject to more volatility than others due to changes in market and economic environment conditions, as a general rule volatility alone does not define a Significant Item. For example, changes in the provision for credit losses, gains/losses from investment activities, asset valuation write-downs, etc., reflect ordinary banking activities and are, therefore, typically excluded from consideration as a Significant Item. Management believes the disclosure of “Significant Items”, when appropriate, aids analysts/investors in better understanding corporate performance and trends so that they can ascertain which of such items, if any, they may wish to include/exclude from their analysis of the company’s performance - i.e., within the context of determining how that performance differed from their expectations, as well as how, if at all, to adjust their estimates of future performance accordingly. To this end, Management has adopted a practice of listing “Significant Items” in its external disclosure documents (e.g., earnings press releases, quarterly performance discussions, investor presentations, Forms 10-Q and 10-K). “Significant Items” for any particular period are not intended to be a complete list of items that may materially impact current or future period performance. A number of items could materially impact these periods, including those described in Huntington’s 2016 Annual Report on Form 10-K and other factors described from time to time in Huntington’s other filings with the Securities and Exchange Commission.
