2 Disclaimer Non-GAAP Information Certain measures included in this document are “non-GAAP,” meaning they are not presented in accordance with generally accepted accounting principles in the U.S. and also are not codified in U.S. banking regulations currently applicable to FHN. FHN’s management believes such measures, even though not always comparable to non-GAAP measures used by other financial institutions, are relevant to understanding the financial condition, capital position, and financial results of FHN and its business segments. The non-GAAP measures presented in this document are listed, and are reconciled to the most comparable GAAP presentation, in the non-GAAP reconciliation table(s) appearing in the Appendix. In addition, presentation of regulatory measures, even those which are not GAAP, provide a meaningful base for comparability to other financial institutions subject to the same regulations as FHN. Although not GAAP terms, these regulatory measures are not considered “non-GAAP” under U.S. financial reporting rules as long as their presentation conforms to regulatory standards. Regulatory measures used in this document include: common equity tier 1 capital, generally defined as common equity less goodwill, other intangibles, and certain other required regulatory deductions; tier 1 capital, generally defined as the sum of core capital (including common equity and instruments that cannot be redeemed at the option of the holder) adjusted for certain items under risk based capital regulations; and risk-weighted assets, which is a measure of total on- and off-balance sheet assets adjusted for credit and market risk, used to determine regulatory capital ratios. Forward-Looking Statements This document contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements pertain to FHN's beliefs, plans, goals, expectations, and estimates. Forward-looking statements are not a representation of historical information, but instead pertain to future operations, strategies, financial results, or other developments. Forward- looking statements can be identified by the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “should,” “is likely,” “will,” “going forward,” and other expressions that indicate future events and trends. Forward-looking statements are necessarily based upon estimates and assumptions that are inherently subject to significant business, operational, economic, and competitive uncertainties and contingencies, many of which are beyond FHN’s control, and many of which, with respect to future business decisions and actions (including acquisitions and divestitures), are subject to change and could cause FHN’s actual future results and outcomes to differ materially from those contemplated or implied by forward-looking statements or historical performance. Examples of uncertainties and contingencies include those mentioned: in this document; in Items 2.02 and 7.01 of FHN’s Current Report on Form 8-K to which this document has been filed as an exhibit; in the forepart, and in Items 1, 1A, and 7, of FHN’s most recent Annual Report on Form 10-K; and in the forepart, and in Item 1A of Part II, of FHN’s Quarterly Report(s) on Form 10-Q filed this year. FHN assumes no obligation to update or revise any forward-looking statements that are made in this document or in any other statement, release, report, or filing from time to time.
