UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following financial statements show unaudited pro forma condensed combined consolidated financial information about the financial condition and results of operations, including per share data, after giving effect to the merger between First Horizon National Corporation (“First Horizon”) and IBERIABANK Corporation (“IBKC”) as well as the purchase of certain branches of Truist Bank by First Horizon Bank (the “Truist Purchase”) and other pro forma adjustments. The transactions were accounted for under the acquisition method of accounting with the assets and liabilities of IBKC and the purchased branches of Truist Bank generally recorded by First Horizon at their respective fair values as of the date the transactions were completed. The unaudited pro forma condensed balance sheet gives effect to the transactions as if the transactions had occurred on June 30, 2020. The unaudited pro forma condensed combined income statements for the six months ended June 30, 2020, and the year ended December 31, 2019, give effect to the transactions as if the transactions had become effective at January 1, 2019. The unaudited selected pro forma combined financial information has been derived from and should be read in conjunction with First Horizon’s Quarterly Report on Form 10-Q for the period ended June 30, 2020, and Annual Report on Form 10-K for the year ended December 31, 2019, and IBKC’s Quarterly Report on Form 10-Q for the period ended March 31, 2020, and Annual Report on Form 10-K for the year ended December 31, 2019.

The IBKC merger was announced on November 4, 2019, and was completed on July 1, 2020. In the merger each outstanding share of IBKC common stock was canceled and converted into the right to receive 4.584 shares of First Horizon common stock. Accordingly, First Horizon issued an aggregate of 243,015,231 of its shares of common stock as merger consideration.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not indicate the financial results of the combined company had the companies actually been combined at the beginning of each period presented, nor the impact of possible business model changes. The unaudited pro forma condensed combined financial information also does not consider any potential effects of changes in market conditions on revenues, expense efficiencies, asset dispositions, and share repurchases, among other factors.

Note 1 - Basis of Presentation

The unaudited pro forma combined consolidated financial information and explanatory notes have been prepared to illustrate the effects of the merger involving First Horizon and IBKC and the Truist Purchase under the acquisition method of accounting with First Horizon treated as the acquirer. The unaudited pro forma combined consolidated financial information is presented for illustrative purposes only and does not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of each period presented, nor does it necessarily indicate the results of operations in future periods or the future financial position of the combined entities. Under the acquisition method of accounting, the assets and liabilities from the merger and Truist Purchase as of their respective effective dates will generally be recorded by First Horizon at their respective fair values with the excess/shortfall of purchase price over/under the acquired net assets allocated to goodwill/recorded as a purchase accounting gain.

The merger, which closed on July 1, 2020, provided for IBKC common shareholders to receive 4.584 shares of First Horizon common stock for each share of IBKC common stock they held immediately prior to the merger closing. Based on the closing trading price of First Horizon common stock on the NYSE on July 1, 2020, the value of the merger consideration per share of IBKC common stock was $43.09. The aggregate amount of consideration, inclusive of consideration for common and preferred stock, equity awards, and cash in lieu of fractional shares was $2,501,555.

The Truist Purchase, which closed on July 17, 2020, resulted in the acquisition of branch loans and related fixed assets and the assumption of branch deposits of Truist Bank by First Horizon for approximately $521 million in cash.

The accounting policies of both First Horizon and IBKC are in the process of being reviewed in detail. Upon completion of such review, conforming adjustments or financial statement reclassification may be determined.

Note 2 - Preliminary Purchase Price Allocation for the Truist Purchase

The pro forma adjustments for the Truist Purchase include the estimated acquisition accounting entries to record the purchase of branch loans and related fixed assets and the assumption of branch deposits, as well as conformity adjustments to align with First Horizon’s presentation. The excess of the purchase price over the fair value of net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma combined consolidated financial statements are based upon available information and certain assumptions considered reasonable, and may be subject to change as additional information becomes available.

Provisional other intangible assets of $7.0 million are included in the Truist Purchase pro forma adjustments separate from goodwill and are amortized using the sum-of-the-years-digits method or an accelerated methodology that mirrors the discounted cash flows used in the determination of fair value. Provisional goodwill totaling $77.6 million is included in the Truist Purchase pro forma adjustments and is not subject to amortization.

Note 4 - Pro Forma Adjustments

The following pro forma adjustments have been reflected in the unaudited pro forma combined consolidated financial information.

Note 5 - Estimated Cost Savings and Merger Integration Costs

First Horizon expects to realize approximately $170 million, or approximately 25 percent of IBKC’s annualized noninterest expense over the last twelve months, in annual pre-tax cost savings following the merger. The estimated cost savings is expected to be 75 percent realized in the run-rate by the end of fiscal year 2021 and fully realized during fiscal year 2022 and is excluded from this pro forma analysis.

Anticipated merger and integration-related costs are not included in the pro forma combined statements of income since they will be recorded in the combined results of income as they are incurred prior to, or after completion of, the merger and are not indicative of what the historical results of the condensed combined company would have been had the companies been actually combined during the periods presented. Anticipated merger and integration-related pre-tax costs are estimated to be $440 million.

Anticipated provision expense for Non-PCD loans for both the IBKC merger and the Truist purchase are not included in the pro forma statements of income. In accordance with generally accepted accounting principles these amounts are reflected in current period earnings. FHN anticipates recognizing approximately $160 million of provision expense in third quarter 2020 for Non-PCD loans related to the IBKC merger and Truist purchase.
