CAUTION REGARDING FORWARD-LOOKING STATEMENTS
This presentation may contain certain forward-looking statements, including certain plans, expectations, goals, projections, and statements about the benefits of the proposed transaction, the merger parties’
plans, objectives, expectations and intentions, the expected timing of completion of the transaction, and other statements that are not historical facts.  Such statements are subject to numerous assumptions,
risks, and uncertainties. Statements that do not describe historical or current facts, including statements about beliefs and expectations, are forward-looking statements. Forward-looking statements may be
identified by words such as expect, anticipate, believe, intend, estimate, plan, target, goal, or similar expressions, or future or conditional verbs such as will, may, might, should, would, could, or similar
variations. The forward-looking statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934, and the
Private Securities Litigation Reform Act of 1995.
While there is no assurance that any list of risks and uncertainties or risk factors is complete, below are certain factors which could cause actual results to differ materially from those contained or implied in the
forward-looking statements: changes in general economic, political, or industry conditions, uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Federal Reserve Board,
volatility and disruptions in global capital and credit markets; movements in interest rates; competitive pressures on product pricing and services; success, impact, and timing of Huntington’s business strategies,
including market acceptance of any new products or services implementing Huntington’s “Fair Play” banking philosophy; the nature, extent, timing, and results of governmental actions, examinations, reviews,
reforms, regulations, and interpretations, including those related to the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Basel III regulatory capital reforms, as well as those involving the
OCC, Federal Reserve, FDIC, and CFPB, and the regulatory approval process associated with the merger; the possibility that the proposed transaction does not close when expected or at all because required
regulatory, shareholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all; the possibility that the anticipated benefits of the transaction are not
realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the
areas where Huntington and FirstMerit do business; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of
management’s attention from ongoing business operations and opportunities; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or
completion of the transaction; Huntington’s ability to complete the acquisition and integration of FirstMerit successfully; and other factors that may affect future results of Huntington and FirstMerit. Additional
factors that could cause results to differ materially from those described above can be found in Huntington’s Annual Report on Form 10-K for the year ended December 31, 2014 and in its subsequent Quarterly
Reports on Form 10-Q, including for the quarter ended September 30, 2015, each of which is on file with the Securities and Exchange Commission (the “SEC”) and available in the “Investor Relations” section

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 2015 third quarter earnings press release, or the Form 8-K related to this
document, all of which can be found on Huntington’s website at www.huntington-ir.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 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 disclosed
separately, with this then being the amount used to calculate the earnings per share equivalent.
Rounding
Please note that columns of data in the presentation may not add due to rounding.
Basis of Presentation

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 2014 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.
