IBERIABANK CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

NOTE 1 - BASIS OF PRESENTATION

General

IBERIABANK Corporation is a financial holding company with locations in Louisiana, Arkansas, Tennessee, Alabama, Texas, Florida, Georgia, South Carolina, North Carolina, Mississippi, Missouri, and New York offering commercial, private banking, consumer, small business, wealth and trust management, retail brokerage, mortgage, and title insurance services. The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts reported in prior periods have been reclassified to conform to the current period presentation. These reclassifications did not have a material effect on previously reported consolidated financial statements.

The accompanying unaudited consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information or footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal and recurring items, necessary for a fair presentation of the consolidated financial statements have been made. These interim financial statements should be read in conjunction with the audited consolidated financial statements and footnote disclosures for the Company previously filed with the SEC in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 ("2017 10-K"). Operating results for the period ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.

When we refer to the “Company,” “we,” “our,” or “us” in this Report, we mean IBERIABANK Corporation and subsidiaries (consolidated). When we refer to the “Parent,” we mean IBERIABANK Corporation. See the Glossary of Defined Terms at the end of this Report for terms used throughout this Report.

Concentrations of Credit Risk

Most of the Company’s business activity is with customers located in the southeastern United States. The Company’s lending activity is concentrated in its market areas within those states. The Company has emphasized originations of commercial loans and private banking loans, defined as loans to higher net worth clients. Repayments on loans are expected to come from cash flows of the borrower and/or guarantor. Losses on secured loans are limited by the net realizable value of the collateral upon default of the borrowers and guarantor support. The Company believes it does not have any excessive concentrations to any one industry, loan type, or customer.

NOTE 2 - RECENT ACCOUNTING PRONOUNCEMENTS

Pronouncements adopted during the nine months ended September 30, 2018:

ASU No. 2014-09

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which implements a common revenue standard and clarifies the principles used for recognizing revenue. The amendments in the ASU clarify that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Revenue from Contracts with Customers

The majority of the Company’s income streams (e.g., interest and dividend income and mortgage income) are accounted for in accordance with GAAP literature outside the scope of ASC 606, Revenue from Contracts with Customers. Details regarding income recognition for interest and non-interest streams can be found throughout the Company’s 2017 10-K (including Note 1 - Summary of Significant Accounting Policies). Impairment losses recognized against certain receivables (e.g., NSF fees) and capitalized costs (e.g., sales commissions) associated with contracts within the scope of ASC 606 are immaterial.

Non-interest income from service charges on deposit accounts, broker commissions, ATM/debit card fee income, credit card and merchant-related income (e.g., interchange fees), and transactional income from traditional banking services (part of other non-interest income) are the significant income streams within the scope of ASC 606 associated with the IBERIABANK reportable segment. Non-interest income from title revenue is associated with the LTC reportable segment.

Recognition of Revenue from Contracts with Customers

The Company enters into various contracts with customers to provide traditional banking services, including asset management, on a routine basis. The Company’s performance obligations are generally service-related and provided on a daily or monthly basis. The Company does not typically have performance obligations which extend beyond a reporting period. The performance obligations are generally satisfied upon completion of service (i.e., as services are rendered) and the fees are collected at such time, or shortly thereafter. The fees are readily determinable and allocated individually to each service. It is not typical for contracts to require significant judgment to determine the transaction price. Some contracts contain variable consideration; however, the variable consideration is generally constrained (not estimable) as it is based on the occurrence or nonoccurence of a contingent event (or another constraint in some circumstances). The Company generally records the variable consideration when the contingent event occurs and the fee is determinable.

The Company provides some services for customers in which it acts in an agent capacity, but generally acts in a principal capacity. Payment terms and conditions vary slightly amongst services; however, amounts are generally invoiced and due or collected by the Company within 30 days, although some fees may be prepaid. The Company bills the customer periodically as performance obligations are satisfied for most services. Therefore, revenue for services provided is generally recognized in the amount invoiced (except in circumstances of prepayment) as that amount corresponds directly to the value of the Company’s performance. In the normal course of business, the Company does not generally grant refunds for services provided. As such, the Company does not establish provisions for estimated returns.

Title revenue associated with services provided by LTC, as well as broker commissions, ATM/debit card fee income, credit card and merchant-related income (e.g., interchange fees), and transactional fees from traditional banking services generated within IBERIABANK are generally recognized at the point-in-time the services are provided. The Company has determined this recognition to be appropriate as, upon completion of services, the Company has completed its performance obligations, has a present right to payment (or has collected the cash), and the customer is able to obtain (or has obtained) substantially all of the benefits from the performance obligation (i.e., the provided services). Revenues from service charges on deposit accounts are recognized at the end of the monthly service period (e.g., account service charges) or the date the performance obligation is satisfied (e.g., NSF, stop payment, wire transfer, etc.), except for deposit account services performed by Treasury Management which are recognized on a monthly basis, as these services are performed over that time. Asset management fees (e.g., trust fees) are generally recognized at the end of the monthly service period, but fees are not collected until the beginning of the subsequent month, although some contracts may have quarterly terms and/or be prepaid. NSF fees which are not initially paid are subsequently recorded as “loans” (along with the overdraft balance) and remain classified as such until the amount is paid or charged-off (generally after 60 days).

Adoption of ASC 606

The Company adopted ASC 606 as of January 1, 2018 for all contracts as of the effective date. Prior period amounts have been reclassified to conform to current guidance requirements related to the net presentation of certain costs associated with interchange fees and rewards programs. The reclassification of prior period amounts reduced non-interest income and non-interest expense by an immaterial amount (approximately $2.2 million and $6.6 million for the three and nine months ended September 30, 2017, respectively) and had no impact on net income. There was no cumulative adjustment made to opening retained earnings as of January 1, 2018.

ASU No. 2016-01

In January 2016, the FASB issued ASU No. 2016-01, Financial Statements - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which impacts how the Company measures certain equity investments and discloses and presents certain financial instruments through the application of the “exit price” notion.

The Company adopted the amendments beginning January 1, 2018. Under the new guidance, equity investments can no longer be classified as trading or available for sale (AFS), and related unrealized holding gains and losses can no longer be recognized in OCI. Per the ASU, such equity investments should be measured at fair value, with adjustments recognized in earnings at the end of each reporting period. As such, the Company reclassified its portfolio of equity investments (which were insignificant at the adoption date and at September 30, 2018) previously classified as AFS investment securities to “other assets.” As these equity investments were previously measured at fair value, implementation of the ASU did not impact the Company’s valuation method. In accordance with the adoption of the ASU, the Company recorded a cumulative-effect adjustment to retained earnings for previously recorded fair value adjustments related to these equity investments, which was insignificant.

The Company elected the practical expedient measurement alternative to prospectively account for other equity investments that do not have readily determinable fair values at cost less impairment plus or minus observable price changes in orderly transactions for an identical or similar investment of the same issuer. These investments are insignificant overall and are classified within “other assets” on the Company’s consolidated balance sheets.

The Company also modified its fair value methodology for loans measured at amortized cost whose fair values were previously disclosed using an “entry price” methodology to an “exit price” methodology, in accordance with the ASU. The Company’s “exit price” methodology estimates the fair value of these loans based on the present value of the future cash flows using the interest rate that would be charged for a similar loan to a borrower with similar risk at the indicated balance sheet date, adjusted for a liquidity discount based on the estimated time period to complete a sale transaction with a market participant.

ASU No. 2016-15

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (ASC 230): Classification of Certain Cash Receipts and Cash Payments, in order to reduce current diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows.

The Company retrospectively adopted the amendments effective January 1, 2018. The adoption of these amendments did not impact the Company’s consolidated statements of cash flows.

ASU No. 2017-04

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (ASC 350): Simplifying the Test for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Therefore, any carrying amount which exceeds the reporting unit’s fair value (up to the amount of goodwill recorded) will be recognized as an impairment loss.

The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.

The Company elected to early adopt the guidance, effective September 30, 2018. The adoption of the guidance did not impact the Company’s consolidated financial statements in the current period. The Company will apply the guidance prospectively, beginning with its annual impairment test as of October 1, 2018.

12

ASU No. 2017-12

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (ASC 815): Targeted Improvements to Accounting for Hedging Activities, which amends the hedge accounting model to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results.

The Company elected to early adopt the amendments effective January 1, 2018. The modified-retrospective adoption of the amendments did not impact the Company’s consolidated financial statements in the current or prior periods.

ASU 2018-15

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The guidance requires customers in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. ASC 350-40 requires the capitalization of certain costs incurred only during the application development stage (e.g., costs of integration with on-premises software, coding, configuration, and customization). ASC 350-40 also requires entities to expense costs during the preliminary project and post-implementation stages (e.g., costs of project planning, training, maintenance after implementation, data conversion) as they are incurred. The accounting for the service element of the arrangement is not affected by the ASU.

Capitalized implementation costs related to a hosting arrangement that is a service contract should be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. The expense related to the capitalized implementation costs should be presented in the same line item in the income statement as the fees associated with the hosting element of the arrangement. Capitalized implementation costs should be presented in the same line item in the statement of financial position that a prepayment of the fees for the associated hosting arrangement would be presented. Payments for capitalized implementation costs should be classified in the statement of cash flows in the same manner as payments of the fees for the service component of the hosting arrangement (typically operating cash flows). The amendments further require entities to disclose the nature of their hosting arrangements that are service contracts and make the disclosures in ASC 360-10 as if the capitalized implementation costs were a separate major class of depreciable asset.

The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. Entities have the option to apply the guidance retrospectively or prospectively to all implementation costs incurred after the date of adoption.

The Company elected to early adopt the guidance prospectively, effective August 31, 2018. The adoption of the guidance did not impact the Company’s consolidated financial statements in the current period.

Pronouncements issued but not yet adopted:

ASU No. 2016-02 and ASU No. 2018-11

In February 2016, the FASB issued ASU No. 2016-02, Leases (ASC 842). A significant amendment to existing GAAP from this ASU is the recognition of lease assets (i.e., right of use assets) and liabilities on the balance sheet for leases that are classified as operating leases by lessees. The lessor model remains similar to the current accounting model in existing GAAP. Additional amendments include, but are not limited to, the elimination of leveraged leases; modification to the definition of a lease; amendments on sale and leaseback transactions; and disclosure of additional quantitative and qualitative information.

ASU 2016-02 will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted.

In July 2018, the FASB issued ASU No. 2018-11, Leases (ASC 842): Targeted Improvements. The amendments include an optional transition method to apply ASU 2016-02 on a prospective basis as of the effective date, with a cumulative effect adjustment to retained earnings in the period of adoption, instead of applying the guidance using a modified retrospective approach as originally required under ASU 2016-02. ASU 2018-11 also provides lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component under certain circumstances, and clarifies which guidance (ASC 842 or ASC 606) to apply to combined lease and nonlease components.

13

The Company occupies certain banking offices and equipment under operating lease agreements, which currently are not recognized on the consolidated balance sheets. Based on the Company’s preliminary analysis of its current portfolio, the impact to the Company’s consolidated balance sheets is estimated to result in less than a 1% increase in assets and liabilities. The Company has developed an implementation plan and selected a third-party vendor to assist in the implementation and subsequent accounting for leases under the ASUs. The Company will elect the optional transition method and adopt ASU 2016-02 and ASU No. 2018-11 on January 1, 2019. The Company is still assessing other practical expedients it may elect at adoption, the final determination of the incremental borrowing rate, and the impact to regulatory capital ratios, amongst other matters associated with the ASUs.

The adjustment to retained earnings is not expected to be significant based on the transition guidance associated with current sale-leaseback agreements. The Company also anticipates additional disclosures to be provided at adoption.

ASU No. 2016-13

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments. The amendments introduce an impairment model that is based on expected credit losses (“ECL”), rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loans and held-to-maturity securities), including certain off-balance sheet financial instruments (e.g., loan commitments). The measurement of ECL should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics must be grouped together when estimating ECL.

The ASU also amends the current AFS security impairment model for debt securities. The new model will require an estimate of ECL when the fair value is below the amortized cost of the asset through the use of an allowance to record estimated credit losses (and subsequent recoveries). Non-credit related losses will continue to be recognized through OCI.

In addition, the amendments provide for a simplified accounting model for purchased financial assets with a more-than-insignificant amount of credit deterioration since their origination. The initial estimate of expected credit losses would be recognized through an ALLL with an offset (i.e., increase) to the cost basis of the related financial asset at acquisition.

ASU 2016-13 will be effective for fiscal years beginning after December 15, 2019, including interim periods. The amendments will be applied through a modified-retrospective approach, resulting in a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. A prospective transition approach is required for debt securities for which OTTI had been recognized before the effective date. Amounts previously recognized in AOCI as of the date of adoption that relate to improvements in cash flows expected to be collected should continue to be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption should be recorded in earnings when received.

The Company is currently evaluating the impact of the ASU on the Company’s consolidated financial statements. The Company has engaged third-party consultants to assist with the ASU and has developed an implementation plan.

ASU No. 2018-13

In August 2018, the FASB released ASU No. 2018-13, Fair Value Measurement (ASC 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements.

The amendments to the guidance on fair value disclosures eliminate the requirements for all entities to disclose (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) the entity’s policy for the timing of transfers between levels of the fair value hierarchy, and (iii) the entity’s valuation processes for Level 3 fair value measurements.

New disclosure requirements for public entities per the ASU include (i) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period, and (ii) the range and weighted average used to develop significant unobservable inputs and how the weighted average was calculated for recurring and nonrecurring Level 3 fair value measurements, with certain exceptions. For derivative instruments and certain other assets and liabilities, entities are permitted to disclose other quantitative information (such as the median or arithmetic average) if doing so provides a more reasonable and rational reflection of the distribution of unobservable inputs used to develop Level 3 fair value measurements.

14

The amendments also modified disclosure guidance within ASC 820 to clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date, rather than a point in the future. Further, entities that use the practical expedient to measure the fair value of certain investments at their net asset values are required to disclose (i) the timing of liquidation of an investee’s assets, and (ii) the date when redemption restrictions will lapse only if the investee has communicated this information to the entity or announced the timing publicly.

ASU 2018-13 will be effective for fiscal years beginning after December 15, 2019, including interim periods. The guidance on changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 measurements, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty is applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted, including interim periods, and entities may elect to early adopt either (i) the entire standard, or (ii) only the provisions that eliminate or modify disclosure requirements.

The Company is currently evaluating the impact of the ASU on the Company’s consolidated financial statements.

ASU No. 2018-16

In October 2018, the FASB released ASU No. 2018-16, Derivatives and Hedging (ASC 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes, which permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under ASC 815 in addition to the interest rates on direct Treasury obligations of the U.S. government (UST), the London Interbank Offered Rate (LIBOR) swap rate, the OIS Rate based on the Fed Funds Effective Rate, and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate.

For entities that have not already adopted ASU No. 2017-12, Derivatives and Hedging (ASC 815): Targeted Improvements to Accounting for Hedging Activities, ASU 2018-16 is required to be adopted concurrently with the amendments in ASU 2017-12. For entities that already have adopted ASU 2017-12, ASU 2018-16 will be effective for fiscal years beginning after December 15, 2018, including interim periods. Early adoption is permitted in any interim period upon issuance of ASU 2018-16 if an entity already has adopted ASU 2017-12. The amendments should be adopted on a prospective basis for qualifying new or redesignated hedging relationships entered into, on, or after the date of adoption. The implementation of the amendments will not have a significant impact on the Company’s consolidated financial statements based upon its current hedging strategies.

ASU No. 2018-17

In October 2018, the FASB released ASU No. 2018-17, Consolidation (ASC 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities, which improves the consistency of the application of the variable interest entity (VIE) related party guidance for common control arrangements. The amendments require reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in GAAP) when determining whether a decision-making fee is a variable interest.

ASU 2018-17 will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. The amendments should be applied retrospectively with a cumulative-effect adjustment to retained earnings at the beginning of the earliest period presented.

The Company is currently evaluating the impact of the ASU on the Company’s consolidated financial statements.

NOTE 3 –ACQUISITION ACTIVITY

The acquisitions discussed below qualify as business combinations. The Company accounts for business combinations under the acquisition method in accordance with ASC Topic 805, Business Combinations. See Note 1, Summary of Significant Accounting Policies, in the 2017 10-K for a description of the Company's accounting for business combinations.

2018 Acquisitions

Acquisition of Gibraltar

The Company completed the acquisition of Gibraltar Private Bank & Trust Co. ("Gibraltar") on March 23, 2018. The acquisition added $1.5 billion in loans and $1.1 billion in deposits, based on preliminary purchase accounting adjustments. Gibraltar operated eight offices in total, with seven located in the Florida metropolitan statistical areas of Miami, Key West, and Naples and one in New York City.

Under the terms of the Agreement and Plan of Merger, Gibraltar common shareholders received 1.9749 shares of IBERIABANK Corporation common stock for each outstanding share of Gibraltar common stock. Based on the Company's closing common stock price of $77.00 per share on March 23, 2018, the aggregate value of the acquisition consideration paid at the time of closing was approximately $214.7 million.

During the first quarter of 2018, the Company recorded preliminary purchase price allocations related to Gibraltar. Throughout the second and third quarters of 2018, the Company continued to analyze the valuations assigned to the acquired assets and liabilities assumed. Based on new information relating to events or circumstances existing at the acquisition date and revised valuations, the Company updated estimated fair values decreasing goodwill by $2.9 million to $49.6 million during the third quarter of 2018. This decrease is primarily a result of an adjustment to the acquired lease liability. As of September 30, 2018, the Company continues to review its fair value estimates and additional adjustments may be required. The following table summarizes the consideration paid for Gibraltar's net assets and the preliminary fair value estimates of the identifiable assets acquired and liabilities assumed as of the acquisition date.

16

The following is a description of the methods used to determine the fair values of significant assets acquired and liabilities assumed presented above.

Cash and Cash Equivalents: The carrying amount of these assets is a reasonable estimate of fair value based on the short-term nature of these assets.

Investment Securities: Fair values for securities were based on quoted market prices from multiple bond dealers. The simple average of the prices received was used to calculate the adjustments.

Equity Securities: The carrying amount of these securities is a reasonable estimate of fair value based on the short-term nature of these assets.

Loans: Fair values for loans were based on a discounted cash flow methodology that considered factors including loan type, classification status, remaining term of the loan, fixed or variable interest rate, amortization status and current discount rates. The discount rates used for loans were based on current market rates for new originations of comparable loans and included adjustments for any liquidity concerns. The discount rate did not include an explicit factor for credit losses, as that was included as a reduction to the estimated cash flows.

Core Deposit Intangible Assets ("CDI"): The fair value for CDI was estimated based on a discounted cash flow methodology that gave appropriate consideration to expected customer attrition rates, net maintenance cost of the deposit base, alternative costs of funds, and the interest costs associated with the customer deposits. The CDI is being amortized over its estimated useful life of approximately ten years utilizing an accelerated method.

Deposit Liabilities: The fair values used for the demand and savings deposits by definition equal the amount payable on demand at the acquisition date. Fair values for time deposits were estimated using a discounted cash flow analysis, that applied interest rates currently being offered to the contractual interest rates on such time deposits.

Long-term Borrowings: The carrying amount of long-term borrowings at the acquisition date approximated fair value, as the Company immediately paid off the debt upon acquisition.

Acquisition of SolomonParks

On January 12, 2018, the Company's subsidiary, Lenders Title Company ("LTC"), acquired SolomonParks Title & Escrow, LLC ("SolomonParks"). Under the terms of the agreement, LTC paid $3.3 million in cash to acquire eight title offices in the Nashville, Tennessee area, which resulted in goodwill of $3.4 million. In addition, the agreement provides for potential additional cash consideration of up to $750 thousand based on gross revenues over a two-year period after the acquisition.

Information regarding the preliminary allocation of goodwill recorded as a result of these acquisitions to the Company's reportable segments is provided in Note 7 "Goodwill and Other Intangible Assets." The goodwill recorded as a result of these acquisitions is not deductible for tax purposes.

2017 Acquisition

Acquisition of Sabadell United

The Company completed the acquisition of Sabadell United Bank, N.A. ("Sabadell United") from Banco de Sabadell, S.A. ("Banco Sabadell") on July 31, 2017. The acquisition added $4.0 billion in loans and $4.4 billion in deposits after fair value adjustments. The acquisition expanded the Company's presence in Southeast Florida adding 25 offices serving the Miami metropolitan area and three offices in Naples, Sarasota and Tampa.

Under the terms of the Stock Purchase Agreement, Banco Sabadell received $809.2 million in cash and 2,610,304 shares of IBERIABANK Corporation common stock in exchange for 100 percent of Sabadell United's common stock. The cash consideration was financed through two public common stock offerings completed on December 7, 2016, and March 7, 2017.

17

During the third quarter of 2017, the Company recorded preliminary purchase price allocations related to Sabadell United. Throughout the remainder of 2017 and the first six months of 2018, the Company continued to analyze the valuations assigned to the acquired assets and liabilities assumed. Based on new information relating to events or circumstances existing at the acquisition date and revised valuations, the Company updated estimated fair values decreasing goodwill by $21.0 million to $441.0 million during the first six months of 2018. This decrease was primarily a result of a change in the estimated fair value of the acquired loans and deferred tax asset. The valuation of the Sabadell United acquisition was final as of June 30, 2018, therefore there were no measurement period adjustments made during the third quarter of 2018.

The following table summarizes the consideration paid for Sabadell United's net assets and the fair value estimates of identifiable assets acquired and liabilities assumed as of the acquisition date. See Note 3, Acquisition Activity, in the 2017 10-K for a description of the methods used to determine the fair values of significant assets acquired and liabilities assumed presented below.

Information regarding the allocation of goodwill recorded as a result of the acquisition to the Company's reportable segments is provided in Note 7 "Goodwill and Other Intangible Assets." The goodwill recorded as a result of the acquisition is not deductible for tax purposes.

The Company's consolidated financial statements as of and for the period ended September 30, 2018 include the operating results of the acquired assets and liabilities assumed. Due to the system conversion of Sabadell United in October 2017 and subsequent streamlining and integration of the operating activities into those of the Company, historical reporting for the former Sabadell United operations is impracticable and thus disclosure of the revenue from the assets acquired and income before income taxes is impracticable for the period subsequent to acquisition.

The following table presents unaudited pro forma information as if the acquisition occurred on January 1, 2016. The pro forma information does not necessarily reflect the results of operations that would have occurred had the Company acquired Sabadell United on January 1, 2016. Furthermore, cost savings and other business synergies related to the acquisition are not reflected in the pro forma amounts.

This pro forma information combines the historical consolidated results of operations of IBERIABANK and Sabadell United for the periods presented and gives effect to the following non recurring adjustments:

Fair value adjustments: Pro forma adjustment to net interest income of $3.0 million for the three months ended September 30, 2017 and $20.3 million for the nine months ended September 30, 2017 to record estimated amortization of premiums and accretion of discounts on acquired loans, securities, and deposits.

Sabadell United accretion / amortization: Pro forma adjustment to net interest income of $22.3 thousand for the three months ended September 30, 2017 and $1.3 million for the nine months ended September 30, 2017 to eliminate Sabadell United's amortization of premiums and accretion of discounts on previously acquired loans, securities, FDIC indemnification asset, and deposits.

Sabadell United provision for loan losses: Pro forma adjustments were made to provision for loan losses of $918.3 thousand for the three months ended September 30, 2017 and $6.4 million for the nine months ended September 30, 2017 to eliminate the reversal (benefit) of Sabadell United's release of provision for loan losses and to account for the provision for loan losses on new loans originated during the period presented.

Amortization of acquired intangibles: Pro forma adjustment to non-interest expense of $846.6 thousand for the three months ended September 30, 2017 and $5.9 million for the nine months ended September 30, 2017 to record estimated amortization of acquired intangible assets.

Other adjustments: Pro forma results also include adjustments related to the removal of benefit from release of reserve for unfunded lending commitments, removal of FDIC clawback liability expense, adjustments to FDIC insurance and other regulatory assessment expenses and related income tax effects.

The Company assessed the nature of the unrealized losses in its portfolio as of September 30, 2018 and December 31, 2017 to determine if there are losses that should be deemed other-than-temporary. In its analysis of these securities, management considered numerous factors to determine whether there were instances where the amortized cost basis of the debt securities would not be fully recoverable, including, but not limited to:

• The length of time and extent to which the estimated fair value of the securities was less than their amortized cost;

• Whether adverse conditions were present in the operations, geographic area, or industry of the issuer;

• The payment structure of the security, including scheduled interest and principal payments, the issuer’s failures to make scheduled payments, if any, and the likelihood of failure to make scheduled payments in the future;

• Changes to the rating of the security by a rating agency; and

• Subsequent recoveries or additional declines in fair value after the balance sheet date.

Management believes it has considered these factors, as well as all relevant information available, when determining the expected future cash flows of the securities in question. In each instance, management has determined the cost basis of the securities would be fully recoverable. Management also has the intent to hold debt securities until their maturity or anticipated recovery if the security is classified as available for sale. In addition, management does not believe the Company will be required to sell debt securities before the anticipated recovery of the amortized cost basis of the security. As a result of the Company's analysis, no declines in the estimated fair value of the Company's investment securities were deemed to be other-than-temporary at September 30, 2018 or December 31, 2017.

At September 30, 2018, 719 debt securities had unrealized losses of 3.72% of the securities’ amortized cost basis. At December 31, 2017, 544 debt securities had unrealized losses of 1.52% of the securities’ amortized cost basis. The unrealized losses for each of the securities related to market interest rate changes and not credit concerns of the issuers. Additional information on securities that have been in a continuous loss position for over twelve months at September 30, 2018 and December 31, 2017 is presented in the following table:

Acquired Loans

As discussed in Note 3, during the third quarter of 2017, the Company acquired loans with fair values of $4.0 billion from Sabadell United. Certain loans that were acquired in this transaction were covered by loss share agreements between the FDIC and Sabadell United, which were assumed in connection with the Company's acquisition of Sabadell United and afforded IBERIABANK loss protection. In September 2018, the Company terminated its loss share agreements with the FDIC. As a result, there were no covered loans at September 30, 2018. Covered loans were $158.6 million at December 31, 2017. Certain acquired loans from Sabadell United were to customers with addresses outside of the United States. Foreign loans, denominated in U.S. dollars, totaled $228.2 million and $325.5 million at September 30, 2018 and December 31, 2017, respectively.

During the first quarter of 2018, the Company acquired loans with fair values of $1.5 billion from Gibraltar based on preliminary purchase accounting adjustments.

25

Of the total loans acquired from Gibraltar, $1.46 billion were determined to have no evidence of deteriorated credit quality and are accounted for under ASC Topics 310-10 and 310-20. The remaining $10.2 million were determined to exhibit deteriorated credit quality since origination under ASC 310-30. The tables below show the fair value estimates of loans acquired from Gibraltar for these two subsections of the portfolio as of the acquisition date. These amounts are subject to change due to the finalization of purchase accounting adjustments.

(Dollars in thousands)	Acquired Non-Impaired Loans
Contractually required principal and interest at acquisition	$	1,695,918

Troubled Debt Restructurings

Information about the Company’s troubled debt restructurings ("TDRs") at September 30, 2018 and 2017 is presented in the following tables. Modifications of loans that are accounted for within a pool under ASC Topic 310-30 are excluded as TDRs. Accordingly, such modifications do not result in the removal of those loans from the pool, even if the modification of those loans would otherwise be considered a TDR. As a result, all such acquired loans that would otherwise meet the criteria for classification as a TDR are excluded from the tables below.

TDRs totaling $46.0 million and $51.5 million occurred during the nine months ended September 30, 2018 and 2017, respectively, through modification of the original loan terms.

The following table provides information on how the TDRs were modified during the periods indicated:

Of the $46.0 million of TDRs occurring during the nine months ended September 30, 2018, $20.2 million are on accrual status and $25.8 million are on non-accrual status. Of the $51.5 million of TDRs occurring during the nine months ended September 30, 2017, $40.5 million were on accrual status and $11.0 million were on non-accrual status.

Portfolio Segment Risk Factors

Commercial real estate loans include loans to commercial customers for long-term financing of land and buildings or for land development or construction of a building. These loans are repaid through revenues from operations of the businesses, rents of properties, sales of properties and refinances. Commercial and industrial loans and leases represent loans to commercial customers to finance general working capital needs, equipment purchases and leases and other projects where repayment is derived from cash flows resulting from business operations. The Company originates commercial business loans on a secured and, to a lesser extent, unsecured basis.

Residential mortgage loans consist of loans to consumers to finance a primary residence. The vast majority of the residential mortgage loan portfolio is comprised of non-conforming 1-4 family mortgage loans secured by properties located in the Company's market areas and originated under terms and documentation that permit their sale in a secondary market.

Consumer loans are offered by the Company in order to provide a full range of retail financial services to its customers and include home equity, credit card and other direct consumer installment loans. The Company originates substantially all of its consumer loans in its primary market areas. Loans in the consumer segment are sensitive to unemployment and other key consumer economic measures.

Credit Quality

The Company utilizes an asset risk classification system in accordance with guidelines established by the Federal Reserve Board as part of its efforts to monitor commercial asset quality. “Special mention” loans are defined as loans with potential weaknesses that may, if not corrected, result in future deterioration of the loan. Special mention loans do not expose the Company to sufficient risk to warrant adverse classification. For problem assets with identified credit issues, the Company has two primary classifications: “substandard” and “doubtful.”

31

Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full satisfaction of the loan balance outstanding questionable, which makes probability of loss higher based on currently existing facts, conditions, and values. Loans classified as substandard, doubtful, and loss are collectively referred to as classified loans. Criticized loans include all classified loans, as well as loans classified as special mention loans. Loans classified as “Pass” do not meet the criteria set forth for special mention, substandard, or doubtful classification and are not considered criticized. Asset risk classifications are determined at origination or acquisition and reviewed on an ongoing basis. Risk classifications are changed if, in the opinion of management, the risk profile of the customer has changed since the last review of the loan relationship.

The Company’s investment in loans by credit quality indicator is presented in the following tables. Asset risk classifications for commercial loans and leases reflect the classification as of September 30, 2018 and December 31, 2017. Credit quality information in the tables below includes total loans acquired (including acquired impaired loans) at the net loan balance, after the application of premiums/discounts, at September 30, 2018 and December 31, 2017. Loan premiums/discounts represent the adjustment of acquired loans to fair value at the acquisition date, as adjusted for income accretion and changes in cash flow estimates in subsequent periods. Loan premiums/discounts include preliminary discounts recorded on acquired Gibraltar loans, which are subject to change upon receipt of final fair value estimates during the measurement period.

Loan delinquency is the primary credit quality indicator that the Company utilizes to monitor consumer asset quality.

On March 23, 2018, the Company completed its acquisition of Gibraltar. In connection with the acquisition, the Company recorded $49.6 million of goodwill based on preliminary fair value estimates of the assets acquired and liabilities assumed in the business combination as of September 30, 2018. On January 12, 2018, the Company's subsidiary, LTC, completed its acquisition of SolomonParks. In connection with the acquisition, LTC recorded $3.4 million of goodwill based on preliminary estimates. In addition, measurement period adjustments to preliminary fair value estimates related to the acquisition of Sabadell United were updated during the six months ended June 30, 2018, reducing goodwill by $21.0 million. The accounting for the acquisition of Sabadell United was complete as of June 30, 2018. See Note 3 for additional information regarding these acquisitions.

The Company performed the required annual goodwill impairment test as of October 1, 2017. The Company’s annual impairment test did not indicate impairment in any of the Company’s reporting units as of the testing date. Following the testing date, management evaluated the events and changes that could indicate that goodwill might be impaired and concluded that a subsequent interim test was not necessary. The Company is currently in the process of performing its annual impairment test as of October 1, 2018.

Mortgage Servicing Rights

Mortgage servicing rights are recorded at the lower of cost or market value in “other intangible assets” on the Company's consolidated balance sheets and amortized over the remaining servicing life of the loans, with consideration given to prepayment assumptions. Mortgage servicing rights had the following carrying values as of the periods indicated:

Title Plant

The Company held title plant assets recorded in “other intangible assets” on the Company's consolidated balance sheets totaling $6.8 million on September 30, 2018 and $6.7 million on December 31, 2017. The increase in title plant assets was the result of the SolomonParks acquisition during the first quarter of 2018. No events or changes in circumstances occurred during the nine months ended September 30, 2018 to suggest the carrying value of the title plant was not recoverable.

35

Intangible assets subject to amortization

In connection with the acquisition of Gibraltar, the Company recorded $18.5 million of core deposit intangible assets. Core deposit intangible assets are subject to amortization over a ten year period. In connection with the acquisition of SolomonParks, the Company recorded $156 thousand of non-compete agreement intangible assets. Non-compete agreement intangible assets are subject to amortization over a five year period. Definite-lived intangible assets had the following carrying values included in “other intangible assets” on the Company’s consolidated balance sheets as of the periods indicated:

NOTE 8 – DERIVATIVE INSTRUMENTS AND OTHER HEDGING ACTIVITIES

The Company enters into derivative financial instruments to manage interest rate risk, exposures related to liquidity and credit risk, and to facilitate customer transactions. The primary types of derivatives used by the Company include interest rate swap agreements, foreign exchange contracts, interest rate lock commitments, forward sales commitments, written and purchased options and credit derivatives. All derivative instruments are recognized on the consolidated balance sheets as "other assets" or "other liabilities" at fair value, as required by ASC Topic 815, Derivatives and Hedging.

Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. The Company enters into interest rate swap agreements in a cash flow hedge to convert forecasted variable interest payments to a fixed rate on its junior subordinated debt. In addition, the Company has entered into an interest rate collar and designated the instrument as a cash flow hedge of the risk of fluctuations in interest rates, thereby reducing the Company's exposure to variability in cash flows from variable-rate loans.

For cash flow hedges, the effective and ineffective portions of the gain or loss related to the derivative instrument is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated, per the Company’s early adoption of ASU No. 2017-12, Derivatives and Hedging (ASC 815): Targeted Improvements to Accounting for Hedging Activities, as of January 1, 2018. In applying hedge accounting for derivatives, the Company establishes and documents a method for assessing the effectiveness of the hedging derivative and a measurement approach for determining the ineffective aspect of the hedge upon the inception of the hedge.

For derivative instruments that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

Information pertaining to outstanding derivative instruments is as follows:

The Company has entered into risk participation agreements with counterparties to transfer or assume credit exposures related to interest rate derivatives. The notional amounts of risk participation agreements sold were $62.1 million and $86.7 million at September 30, 2018 and December 31, 2017, respectively. Assuming all underlying third party customers referenced in the swap contracts defaulted at September 30, 2018 and December 31, 2017, the exposure from these agreements would not be material based on the fair value of the underlying swaps.

The Company is party to collateral agreements with certain derivative counterparties. Such agreements require that the Company maintain collateral based on the fair values of individual derivative transactions. In the event of default by the Company, the counterparty would be entitled to the collateral.

At September 30, 2018, the Company was not required to post collateral due to the Company's derivative position at the balance sheet date. At December 31, 2017, the Company was required to post $552 thousand in cash or securities as collateral for its derivative transactions, which is included in "interest-bearing deposits in banks" on the Company’s consolidated balance sheets. Effective January 3, 2017, the Chicago Mercantile Exchange and LCH.Clearnet Limited amended their rulebooks to legally characterize variation margin payments for over-the-counter derivatives they clear as settlements of the derivatives' exposure rather than collateral against the exposures. In light of changes to the aforementioned rulebooks, the Board of Governors of the Federal Reserve System, the OCC and the FDIC issued guidance effective August 14, 2017, which is consistent with the SEC's accounting guidance, that allows institutions to treat centrally-cleared derivatives as settled for purposes of the capital rule. At September 30, 2018 and December 31, 2017, the Company was required to post $44.4 million and $5.1 million, respectively, in variation margin payments for its derivative transactions, which is required to be netted against the fair value of the derivatives in "other assets/other liabilities" on the consolidated balance sheets. The Company does not anticipate additional assets will be required to be posted as collateral, nor does it believe additional assets would be required to settle its derivative instruments immediately if contingent features were triggered at September 30, 2018. The Company’s master netting agreements represent written, legally enforceable bilateral agreements that (1) create a single legal obligation for all individual transactions covered by the master agreement and (2) in the event of default, provide the non-defaulting counterparty the right to accelerate, terminate, and close-out on a net basis all transactions under the agreement and to promptly liquidate or set-off collateral posted by the defaulting counterparty. As permitted by U.S. GAAP, the Company does not offset fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral against recognized fair value amounts of derivatives executed with the same counterparty under a master netting agreement.

During the nine months ended September 30, 2018 and 2017, the Company has not reclassified into earnings any gain or loss as a result of the discontinuance of cash flow hedges because it was probable the original forecasted transaction would not occur by the end of the originally specified term.

At September 30, 2018, the Company does not expect to reclassify a material amount from accumulated other comprehensive income into interest income over the next twelve months for derivatives that will be settled.

NOTE 9 – INCOME TAXES

The Company's provision for income taxes for the three and nine months ended September 30, 2018 and 2017 is based on the estimated annual effective tax rate, plus discrete items.

The following table presents the provision for income taxes and the effective tax rates for the periods indicated.

	Three Months Ended September 30,						Nine Months Ended September 30,
(Dollars in thousands)	2018			2017			2018			2017
Income before income tax expense	$	131,866		$	48,450		$	318,620		$	201,493
Income tax expense	30,401			18,806			78,410			69,358
Effective tax rate	23.1		%	38.8		%	24.6		%	34.4		%

The difference between the Company's effective tax rate for the three and nine months ended September 30, 2018 and 2017 and the U.S. statutory tax rates of 21% and 35%, respectively, primarily relates to tax-exempt income, non-deductible expenses, state income taxes (net of federal income tax benefit), and the recognition of tax credits. The effective tax rate may vary significantly due to fluctuations in the amount and source of pretax income, changes in amounts of non-deductible expenses, and timing of the recognition of tax credits. In addition, the difference between the Company's effective tax rate for the nine months ended September 30, 2018 and the U.S. statutory tax rate of 21% primarily relates to the discrete item of $6.6 million in income tax expense due to the write-down of deferred tax assets in the second quarter of 2018 associated with the finalization of the accounting for the Sabadell United acquisition and the related impact of the Tax Act on those adjustments. This adjustment increased the effective tax rate for the nine months ended September 30, 2018 by 2.1% from 22.5% to 24.6%.

Provisional amounts in effective tax rate

On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act (the "Tax Act") into law. Under ASC 740, the effects of changes in tax rates and laws are recognized in the period in which the new legislation is enacted. In the case of U.S. federal income taxes, the enactment date is the date the bill becomes law (i.e., upon presidential signature). Among other provisions, the most significant to the Company is the reduction of the corporate income tax rate from 35% to 21%. With respect to the legislation, the Company recognized a provisional one-time increase in tax expense of $51.0 million as of December 31, 2017 due to a re-measurement of deferred tax assets and liabilities resulting from the decrease in the corporate income tax rate. The Company made no adjustment to the provisional amounts during the third quarter of 2018. During the nine months ended September 30, 2018, the Company recognized an adjustment of $6.6 million in income tax expense due to the write-down of deferred tax assets associated with the finalization of the accounting for the Sabadell United acquisition and the related impact of the Tax Act on those adjustments. This adjustment increased the year-to-date effective tax rate by 2.1% from 22.5% to 24.6%. The accounting for the tax effects of the Tax Act remained incomplete as of September 30, 2018. The Company is in the process of analyzing certain aspects of the Tax Act, obtaining additional information, and refining its calculations, which could potentially affect the measurement of these balances. Information which could result in adjustment to the provisional amount includes, but is not limited to, the filing of the Sabadell United tax returns, elections or changes in IRS tax methods, and further analysis of tax positions. Our estimates may also be affected as we gain a more thorough understanding of the Tax Act. Consistent with the guidance provided under ASC 740, the Company recorded impacts from enactment of the Tax Act in the fourth quarter of 2017 subject to Staff Accounting Bulletin 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act ("SAB 118"). SAB 118 provides a measurement period not to extend beyond one year of the enactment date to adjust the accounting for certain elements of the tax reform.

Common Stock

During the second quarter of 2018, the Company's Board of Directors authorized the repurchase of up to 1,137,500 shares of IBERIABANK Corporation's outstanding common stock. Stock repurchases under this program will be made from time to time, on the open market or in privately negotiated transactions. The timing of these repurchases will depend on market conditions and other requirements. The share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and expires during the second quarter of 2020. The program may be extended, modified, suspended, or discontinued at any time.

During the first nine months of 2018, the Company repurchased 763,210 common shares for approximately $61.0 million at a weighted average cost of $79.99 per share, which included 335,000 common shares repurchased under a plan previously approved by the Board of Directors that has subsequently expired. At September 30, 2018, the remaining common shares that could be repurchased under the current Board-approved plan was 709,290 shares. Subsequent to quarter-end and through November 5, 2018, the Company repurchased the remaining common shares for approximately $52.6 million.

On March 23, 2018, as part of the Gibraltar acquisition, the Company issued 2,787,773 shares of common stock. The aggregate value of the acquisition consideration paid by the Company at the time of closing was approximately $214.7 million based on the Company's closing common stock price of $77.00 per share on March 23, 2018. Gibraltar common shareholders received 1.9749 shares of IBERIABANK Corporation common stock for each outstanding share of Gibraltar common stock. Refer to Note 3, Acquisition Activity, for further detail regarding the Gibraltar acquisition.

Regulatory Capital

The Company and IBERIABANK are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy regulations and the regulatory framework for prompt corrective action, the Company and IBERIABANK, as applicable, must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Management believes that, as of September 30, 2018, the Company and IBERIABANK met all capital adequacy requirements to which they are subject.

As of September 30, 2018, the most recent notification from the FRB categorized IBERIABANK as well-capitalized under the regulatory framework for prompt corrective action (the prompt corrective action requirements are not applicable to the Company). To be categorized as well-capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since the notification that management believes have changed that categorization.

The Company’s and IBERIABANK’s actual capital amounts and ratios as of September 30, 2018 and December 31, 2017 are presented in the following tables:

⁽¹⁾ Minimum capital ratios are subject to a capital conservation buffer. In order to avoid limitations on distributions, including dividend payments, and certain discretionary bonus payments to executive officers, an institution must hold a capital conservation buffer above its minimum risk-based capital requirements. This capital conservation buffer is calculated as the lowest of the differences between the actual CET1 ratio, Tier 1 Risk-Based Capital Ratio, and Total Risk-Based Capital ratio and the corresponding minimum ratios. At September 30, 2018, the required minimum capital conservation buffer was 1.875%, and will increase by 0.625% and be fully phased-in on January 1, 2019 at 2.50%. At September 30, 2018, the capital conservation buffers of the Company and IBERIABANK were 4.42% and 3.89%, respectively.

NOTE 11 – EARNINGS PER SHARE

Share-based payment awards that entitle holders to receive non-forfeitable dividends before vesting are considered participating securities that are included in the calculation of earnings per share using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated for common stock and participating securities according to dividends declared and participating rights in undistributed earnings. Under this method, all earnings, distributed and undistributed, are allocated to common shares and participating securities based on their respective rights to receive dividends.

The following table presents the calculation of basic and diluted earnings per share for the periods indicated.

	Three Months Ended September 30,					Nine Months Ended September 30,
(In thousands, except per share data)	2018			2017		2018			2017
Earnings per common share - basic:

Less: Dividends and undistributed earnings allocated to unvested restricted shares	908			283		2,341			1,052
Net income allocated to common shareholders - basic	$	96,958		$	25,763	$	229,723		$	122,937

Earnings per common share - basic	1.74			0.49		4.17			2.47
Earnings per common share - diluted:
Net income allocated to common shareholders - basic	$	96,958		$	25,763	$	229,723		$	122,937
Adjustment for undistributed earnings allocated to unvested restricted shares	(25		)	8		(49		)	—
Net income allocated to common shareholders - diluted	$	96,933		$	25,771	$	229,674		$	122,937
Weighted average common shares outstanding	55,571			52,424		55,047			49,749
Dilutive potential common shares	374			346		360			357
Weighted average common shares outstanding - diluted	55,945			52,770		55,407			50,106
Earnings per common share - diluted	$	1.73		$	0.49	$	4.14		$	2.45

For the three months ended September 30, 2018, and 2017, the calculations for basic shares outstanding exclude the weighted average shares owned by the RRP of 542,796 and 511,562, respectively. For the nine months ended September 30, 2018, and 2017, basic shares outstanding exclude 581,397 and 428,232 shares owned by the RRP, respectively.

The effects from the assumed exercises of 60,931 and 72,239 stock options were not included in the computation of diluted earnings per share for the three months ended September 30, 2018 and 2017, respectively, because such amounts would have had an antidilutive effect on earnings per common share. For the nine months ended September 30, 2018 and 2017, the effects from the assumed exercise of 147,834 and 69,289 stock options, respectively, were not included in the computation of diluted earnings per share because such amounts would have had an antidilutive effect on earnings per common share.

NOTE 12 – SHARE-BASED COMPENSATION

The Company has various types of share-based compensation plans that permit the granting of awards in the form of stock options, restricted stock, restricted share units and phantom stock. These plans are administered by the Compensation Committee of the Board of Directors, which selects persons eligible to receive awards and determines the terms, conditions and other provisions of the awards. At September 30, 2018, awards of 1,163,414 shares could be made under approved incentive compensation plans. The Company issues shares to fulfill stock option exercises and restricted share units and restricted stock awards vesting from available authorized common shares. At September 30, 2018, the Company believes there are adequate authorized shares to satisfy anticipated stock option exercises and restricted share unit and restricted stock award vesting.

Stock option awards

The Company issues stock options under various plans to directors, officers and other key employees. The option exercise price cannot be less than the fair value of the underlying common stock as of the date of the option grant and the maximum option term cannot exceed ten years.

The following table represents the activity related to stock options during the periods indicated:

	Number of Shares		Weighted Average Exercise Price
Outstanding options, December 31, 2016	721,538		$	55.38
Granted	78,434		85.03
Exercised	(74,236	)	55.77
Forfeited or expired	(26,675	)	68.93
Outstanding options, September 30, 2017	699,061		$	58.15
Exercisable options, September 30, 2017	463,326		$	55.68
Outstanding options, December 31, 2017	686,366		$	58.24

Exercisable options, September 30, 2018	500,349		$	56.70

The Company uses the Black-Scholes option pricing model to estimate the fair value of stock option awards. The following weighted-average assumptions were used for option awards issued during the following periods:

	For the Nine Months Ended September 30,
	2018			2017
Expected dividends	1.8		%	1.7		%
Expected volatility	24.3		%	25.0		%
Risk-free interest rate	2.7		%	2.1		%
Expected term (in years)	5.8			5.8
Weighted-average grant-date fair value	$	18.48		$	18.87

The assumptions above are based on multiple factors, including historical stock option exercise patterns and post-vesting employment termination behaviors, expected future exercise patterns and the expected volatility of the Company’s stock price.

The following table represents the compensation expense that is included in non-interest expense and related income tax benefits in the accompanying consolidated statements of comprehensive income related to stock options for the following periods:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
(Dollars in thousands)	2018		2017		2018		2017
Compensation expense related to stock options	$	322	$	343	$	952	$	1,131
Income tax benefit related to stock options	23		46		70		161

At September 30, 2018, there was $2.2 million of unrecognized compensation expense related to stock options that is expected to be recognized over a weighted-average period of 2.9 years.

Restricted stock awards

The Company issues restricted stock under various plans for certain officers and directors. The restricted stock awards may not be sold or otherwise transferred until certain restrictions have lapsed. The holders of the restricted stock receive dividends and have the right to vote the shares. The compensation expense for these awards is determined based on the market price of the Company's common stock at the date of grant applied to the total number of shares granted and is recognized over the vesting period (generally three to five years). As of September 30, 2018 and 2017, unrecognized share-based compensation expense associated with these awards totaled $30.9 million and $35.7 million, respectively. The unrecognized compensation expense related to restricted stock awards at September 30, 2018 is expected to be recognized over a weighted-average period of 1.4 years.

Restricted share units

During the first nine months of 2018 and 2017, the Company issued restricted share units to certain of its executive officers. Restricted share units vest after the end of a three year performance period, based on satisfaction of the market and performance conditions set forth in the restricted share unit agreements. Recipients do not possess voting or investment power over the common stock underlying such units until vesting. The grant date fair value of these restricted share units is the same as the value of the corresponding number of shares of common stock, adjusted for assumptions surrounding the market-based conditions contained in the respective agreements. See Note 1, Summary of Significant Accounting Policies, in the 2017 10-K for further discussion of restricted share units with market or performance conditions.

The following table represents the compensation expense that was included in non-interest expense and related income tax benefits in the accompanying consolidated statements of comprehensive income related to restricted stock awards and restricted share units for the periods indicated:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
(Dollars in thousands)	2018		2017		2018		2017
Compensation expense related to restricted stock awards and restricted share units	$	4,843	$	4,046	$	14,192	$	10,368

Phantom stock awards

The Company issues phantom stock awards to certain key officers and employees. The awards are subject to a vesting period of five years and are paid out in cash upon vesting. The amount paid per vesting period is calculated as the number of vested “share equivalents” multiplied by the closing market price of a share of the Company’s common stock on the vesting date. Share equivalents are calculated on the date of grant as the total award’s dollar value divided by the closing market price of a share of the Company’s common stock on the grant date. Award recipients are also entitled to a “dividend equivalent” on each unvested share equivalent held by the award recipient. A dividend equivalent is a dollar amount equal to the cash dividends that the participant would have been entitled to receive if the participant’s share equivalents were issued in shares of common stock. Dividend equivalents are reinvested as share equivalents that will vest and be paid out on the same date as the underlying share equivalents on which the dividend equivalents were paid. The number of share equivalents accumulated with a dividend equivalent is determined by dividing the aggregate of dividend equivalents paid on the unvested share equivalents by the closing price of a share of the Company’s common stock on the dividend payment date.

The following table indicates compensation expense recorded for phantom stock based on the number of share equivalents vested at September 30 of the periods indicated and the current market price of the Company’s stock at that time:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
(Dollars in thousands)	2018		2017		2018		2017
Compensation expense related to phantom stock	$	2,375	$	2,747	$	7,388	$	8,689

The following table represents phantom stock award activity during the periods indicated:

(Dollars in thousands)	Number of share equivalents (1)		Value of share equivalents (2)
Balance, December 31, 2016	472,830		$	39,600
Granted	111,119		9,128

Vested share equivalents	(130,497	)	10,871
Balance, September 30, 2018	355,705		$	28,937

⁽¹⁾  Number of share equivalents includes all reinvested dividend equivalents for the periods indicated.

⁽²⁾  Except for share equivalents at the beginning of each period, which are based on the value at that time, and vested share payments, which are based on the cash paid at the time of vesting, the value of share equivalents is calculated based on the market price of the Company’s stock at the end of the respective periods. The market price of the Company’s stock was $81.35 and $82.15 on September 30, 2018, and 2017, respectively.

NOTE 13 – FAIR VALUE MEASUREMENTS

See Note 1, Summary of Significant Accounting Policies, to the consolidated financial statements of the 2017 10-K for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis.

Recurring fair value measurements

The Company has segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to estimate the fair value at the measurement date in the tables below.

Non-recurring fair value measurements

The Company has segregated all assets and liabilities that are measured at fair value on a non-recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the tables below.

	September 30, 2018

The tables above exclude the initial measurement of assets and liabilities that were acquired as part of the business combinations disclosed in Note 3, Acquisition Activity. These assets and liabilities were recorded at their fair value upon acquisition in accordance with U.S. GAAP and were not re-measured during the periods presented unless specifically required by U.S. GAAP. Acquisition date fair values represent either Level 2 fair value measurements (investment securities, deposits, property, and equipment) or Level 3 fair value measurements (loans, core deposit intangible assets, and debt.) Refer to Note 3, Acquisition Activity, for further detail.

The Company did not record any liabilities at fair value for which measurement of the fair value was made on a non-recurring basis as of September 30, 2018 and December 31, 2017.

Fair value option

The Company has elected the fair value option for originated residential mortgage loans held for sale, which allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to hedge them without the burden of complying with the requirements for hedge accounting. The Company also has a portion of mortgage loans held for investment for which the fair value option was elected upon origination and continue to be accounted for at fair value at September 30, 2018 and December 31, 2017, respectively.

The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for mortgage loans held for sale and mortgage loans held for investment measured at fair value:

	September 30, 2018							December 31, 2017
(Dollars in thousands)	Aggregate Fair Value		Aggregate Unpaid Principal		Aggregate Fair Value Less Unpaid Principal			Aggregate Fair Value		Aggregate Unpaid Principal		Aggregate Fair Value Less Unpaid Principal
Mortgage loans held for sale, at fair value	$	42,976	$	41,848	$	1,128		$	134,916	$	131,276	$	3,640
Mortgage loans held for investment, at fair value	7,249		8,666		(1,417		)	14,953		16,306		(1,353		)

49

Interest income on mortgage loans held for sale is recognized based on contractual rates and is reflected in interest income on loans held for sale in the consolidated statements of comprehensive income. The following table details net gains (losses) resulting from the change in fair value of loans that were recorded in mortgage income in the consolidated statements of comprehensive income for the three and nine months ended September 30, 2018 and 2017. The changes in fair value are mostly offset by economic hedging activities, with an insignificant portion of these changes attributable to changes in instrument-specific credit risk.

NOTE 14 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. ASC Topic 825, Financial Instruments, excludes certain financial instruments and all non-financial instruments from its disclosure requirements. Consequently, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.

The carrying amount and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments are included in the tables below. See Note 1, Summary of Significant Accounting Policies, in the 2017 10-K for a description of how fair value measurements are determined, except for loans, amended upon implementation of ASU 2016-01, Financial Statements - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. See Note 2, Recent Accounting Pronouncements, in this Report for a description of how the fair value measurement is determined for loans beginning January 1, 2018.

The fair value estimates presented herein are based upon pertinent information available to management as of September 30, 2018 and December 31, 2017. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since these dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

NOTE 15 – BUSINESS SEGMENTS

Each of the Company’s reportable operating segments serves the specific needs of the Company’s customers based on the products and services it offers. The reportable segments are based upon those revenue-producing components for which separate financial information is produced internally and primarily reflect the manner in which resources are allocated and performance is assessed. Further, the reportable operating segments are also determined based on the quantitative thresholds prescribed within ASC Topic 280, Segment Reporting, and consideration of the usefulness of the information to the users of the consolidated financial statements.

The Company reports the results of its operations through three reportable segments: IBERIABANK, Mortgage, and LTC. The IBERIABANK segment represents the Company’s commercial and retail banking functions, including its lending, investment, and deposit activities. IBERIABANK also includes the Company’s wealth management, capital markets, and other corporate functions. The Mortgage segment represents the Company’s origination, funding, and subsequent sale of one-to-four family residential mortgage loans. The LTC segment represents the Company’s title insurance and loan closing services.

Certain expenses not directly attributable to a specific reportable segment are allocated to segments based on pre-determined methods that reflect utilization. Also within IBERIABANK are certain reconciling items that translate reportable segment results into consolidated results. The following tables present certain information regarding our operations by reportable segment, including a reconciliation of segment results to reported consolidated results for the periods presented. Reconciling items between segment results and reported results include:

• Elimination of interest income and interest expense representing interest earned by IBERIABANK on interest-bearing checking accounts held by related companies, as well as the elimination of the related deposit balances at the IBERIABANK segment;

• Elimination of investment in subsidiary balances on certain operating segments included in total and average segment assets; and

• Elimination of intercompany due to and due from balances on certain operating segments that are included in total and average segment assets.

NOTE 16 – COMMITMENTS AND CONTINGENCIES

Off-balance sheet commitments

In the normal course of business, to meet the financing needs of its customers, the Company is a party to credit-related financial instruments, with risk not reflected in the consolidated financial statements. These financial instruments include commitments to extend credit, standby letters of credit, and commercial letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The credit policies used for these commitments are consistent with those used for on-balance sheet instruments. The Company’s exposure to credit loss in the event of non-performance by its customers under such commitments or letters of credit represents the contractual amount of the financial instruments as indicated in the table below. At September 30, 2018, the fair value of guarantees under commercial and standby letters of credit was $2.4 million compared to $2.1 million at December 31, 2017. This fair value will decrease as the existing commercial and standby letters of credit approach their expiration dates.

At September 30, 2018 and December 31, 2017, respectively, the Company had the following financial instruments outstanding and related reserves, whose contract amounts represent credit risk:

(Dollars in thousands)	September 30, 2018		December 31, 2017
Commitments to extend credit	$	824,472	$	342,305
Unfunded commitments under lines of credit	6,610,843		6,060,034
Commercial and standby letters of credit	235,730		210,002
Reserve for unfunded lending commitments	14,721		13,208

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee by the borrower. Since many of the commitments are expected to be drawn upon, the total commitment amounts generally represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral, if any, is based on management’s credit evaluation of the customer.

Unfunded commitments under commercial lines of credit, revolving credit lines, and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. Many of these types of commitments do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed. See Note 6, Allowance for Credit Losses and Credit Quality, for additional information related to the Company’s reserve for unfunded lending commitments.

Commercial and standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper issuance, bond financing, and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. When necessary they are collateralized, generally in the form of marketable securities and cash equivalents.

Legal proceedings

The nature of the business of the Company’s banking and other subsidiaries ordinarily results in a certain amount of claims, litigation, investigations, and legal and administrative cases and proceedings, which are considered incidental to the normal conduct of business. Some of these claims are against entities or assets of which the Company is a successor or acquired in business acquisitions. The Company has asserted defenses to these claims and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interest of the Company and its shareholders.

56

In July of 2016, the Company received a subpoena from the Office of Inspector General of the U.S. Department of Housing and Urban Development (“HUD”) requesting information on certain previously originated loans insured by the Federal Housing Administration ("FHA") as well as other documents regarding the Company's FHA-related policies and practices. After the Company complied with the subpoena, attorneys from the Department of Justice (“DOJ”) informed the Company in late March of 2017 that a civil qui tam suit had been filed against the Company in federal court involving the subject matter of the HUD subpoena. The HUD lawsuit was settled on December 11, 2017 in the amount of $11.7 million. On February 2, 2018, IBERIABANK filed a lawsuit in the United States District Court for the Eastern District of Louisiana (New Orleans) against Illinois Union Insurance Company and Travelers Casualty and Surety Company of America in an effort to recover the $11.7 million it paid to settle the HUD matter. IBERIABANK filed that lawsuit to recover the insurance proceeds to which it claims to be entitled under certain Bankers’ Professional Liability insurance policies issued by defendants Illinois Union and Travelers. More specifically, IBERIABANK alleges that the insurers have failed to honor their obligations under the policies to pay IBERIABANK’s losses in connection with the $11.7 million settlement of disputed allegations relating to IBERIABANK’s professional services in connection with certain mortgage loans insured by the FHA.

The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal reserves may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of loss is not estimable, the Company does not accrue legal reserves. While the outcome of legal proceedings is inherently uncertain, based on information currently available and available insurance coverage, the Company’s management believes that it has established appropriate legal reserves. Any incremental liabilities arising from pending legal proceedings are not expected to have a material adverse effect on the Company’s consolidated financial position, consolidated results of operations, or consolidated cash flows. However, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the Company’s consolidated financial position, consolidated results of operations, or consolidated cash flows.

As of the date of this filing, the Company believes the amount of losses associated with legal proceedings that it is reasonably possible to incur above amounts already accrued and reported as of September 30, 2018 is not material.

57

NOTE 17 – RELATED PARTY TRANSACTIONS

In the ordinary course of business, the Company may execute transactions with various related parties. Examples of such transactions may include lending or deposit arrangements, transfers of financial assets, services for administrative support, and other miscellaneous items.

The Company has granted loans to executive officers and directors and their affiliates. These loans, including the related principal additions, principal payments, and unfunded commitments are not material to the consolidated financial statements at September 30, 2018 and December 31, 2017. There were no outstanding loans to such related parties classified as non-accrual, past due, or troubled debt restructurings at September 30, 2018.

Deposits from related parties held by the Company were not material at September 30, 2018 and December 31, 2017.

EXECUTIVE SUMMARY

Corporate Profile

The Company is a $30.1 billion financial holding company with locations in Louisiana, Arkansas, Tennessee, Alabama, Texas, Florida, Georgia, South Carolina, North Carolina, Mississippi, Missouri, and New York offering commercial, private banking, consumer, small business, wealth and trust management, retail brokerage, mortgage, and title insurance services.

A summary of the Company's financial position and results of operations as of and for the three and nine months ended September 30, 2018 is provided below, with further detail provided in subsequent sections of Management's Discussion and Analysis.

Results in 2018 were impacted by the following significant items:

• The Company acquired Sabadell United on July 31, 2017 for total consideration of $1.0 billion. The acquisition added $4.0 billion in loans and $4.4 billion in deposits (including approximately $0.9 billion of non-interest bearing deposits), and significantly impacted results in the first nine months of 2018 when compared to the same period of 2017. Acquired earning assets, offset by a lesser amount of acquired interest-bearing liabilities, resulted in higher net interest income. The acquisition benefited certain non-interest income streams, such as service charges on deposit accounts and trust department income, while additional associates and acquired locations increased salaries and employee benefits and net occupancy and equipment expenses.

• The Company acquired Gibraltar on March 23, 2018 for total consideration of $214.7 million. The acquisition added $1.5 billion in loans and $1.1 billion in deposits. The Company incurred approximately $1.0 million and $31.5 million in pre-tax merger-related expenses during the three and nine months ended September 30, 2018, resulting in a $0.01 and $0.44 reduction to GAAP EPS, respectively.

• On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act (the "Tax Act") into law. Among other provisions, the most significant to the Company is the reduction of the corporate income tax rate from 35% to 21%, effective January 1, 2018. The reduction in the corporate tax rate resulted in an estimated $0.23 benefit to GAAP EPS in the third quarter of 2018 and an estimated $0.56 benefit to GAAP EPS for the nine months ended September 30, 2018. The impact on EPS includes the federal statutory income tax rate change from 35% to 21% and eliminating the deduction for FDIC insurance.

The following summarizes third quarter 2018 results compared to third quarter 2017 results:

• Net income available to common shareholders for the three months ended September 30, 2018 totaled $97.9 million, or $1.73 diluted EPS, compared to $26.0 million, or $0.49 diluted EPS, for the same period of 2017. Non-GAAP core EPS, which excludes merger-related costs and other items (disclosed in Table 17 - Non-GAAP measures), was $1.74 in the third quarter of 2018 compared to $1.00 for the same period of 2017.

• Net interest income was $259.2 million for the third quarter of 2018, a $42.3 million, or 20%, increase compared to the same quarter of 2017. The increase in net interest income was primarily volume-related due to the Sabadell United and Gibraltar acquisitions, but was also impacted by higher earning asset yields offset by higher funding costs, ultimately resulting in a 10 basis points increase to net interest margin on a tax-equivalent basis to 3.74% from 3.64%.

• Non-interest income for the third quarter of 2018 increased $2.2 million, or 4%, when compared to the same period of 2017, primarily driven by increases in client derivative activity, services charges on deposit accounts and trust department income, offset by a decrease in mortgage income.

• Non-interest expense for the third quarter of 2018 decreased $31.4 million, or 16%, to $169.3 million compared to the same period of 2017, largely due to lower acquisition-related expenses and a decrease in legal fees from the HUD litigation accrual which was recorded in the third quarter of 2017.

• The Company recorded a provision for loan and lease losses of $11.1 million for the quarter ended September 30, 2018, a $7.4 million, or 40%, decrease from the provision recorded for the same period of 2017, primarily driven by an improvement in asset quality.

60

• Income before income tax expense increased $83.4 million to $131.9 million for the three months ended September 30, 2018, compared to the same period of 2017; however, income tax expense only increased $11.6 million to $30.4 million for the third quarter of 2018. Income tax expense was impacted in 2018 by the reduction of the corporate income tax rate from 35% to 21%, effective January 1, 2018. The effective tax rate was 23.1% and 38.8%, respectively, for the three months ended September 30, 2018 and 2017.

The following summarizes year-to-date 2018 results compared to 2017 results:

• Net income available to common shareholders for the nine months ended September 30, 2018 totaled $232.1 million, or $4.14 diluted EPS, compared to $124.0 million, or $2.45 diluted EPS, for the same period of 2017. Non-GAAP core EPS, which excludes merger-related costs and other items (disclosed in Table 17 - Non-GAAP measures), was $4.83 in the first nine months of 2018 compared to $3.13 for the same period of 2017.

• Net interest income was $748.2 million for the first nine months of 2018, a $174.9 million, or 31%, increase compared to the same period of 2017. The increase in net interest income was primarily volume-related due to the Sabadell United and Gibraltar acquisitions, but was also impacted by higher earning asset yields offset by higher funding costs. Net interest margin on a tax-equivalent basis increased 9 basis points to 3.72% from 3.63%.

• Non-interest income increased $1.8 million, or 1%, to $151.6 million during the nine months ended September 30, 2018, primarily due to increases in certain of the Company's fee income businesses, offset by a decrease in mortgage income.

• Non-interest expense for the first nine months of 2018 increased $69.6 million, or 14%, to $554.5 million compared to the same period of 2017, largely due to acquisition-related increases in salaries and employee benefits expense, branch closure expenses, amortization of intangibles, net occupancy and equipment expenses, and other merger and conversion-related expenses.

• The Company recorded a provision for loan and lease losses of $26.7 million for the first nine months of 2018, a $10.0 million, or 27%, decrease from the provision recorded for the same period of 2017, primarily driven by an improvement in asset quality in the first nine months 2018.

• Income before income tax expense increased $117.1 million to $318.6 million for the nine months ended September 30, 2018 compared to the same period of 2017; however, income tax expense only increased $9.1 million to $78.4 million for the first nine months of 2018. Income tax expense was impacted in 2018 by the reduction of the corporate income tax rate from 35% to 21%, effective January 1, 2018. This was partially offset by a $6.6 million write-down of deferred tax assets in the second quarter of 2018 associated with the finalization of the accounting for the Sabadell United acquisition and the related adjustment to provisional amounts recorded upon enactment of the Tax Act. The effective tax rate was 24.6% and 34.4%, respectively, for the nine months ended September 30, 2018 and 2017.

Summary of Financial Condition at September 30, 2018 Compared to December 31, 2017:

• Total assets at September 30, 2018 were $30.1 billion, up $2.2 billion, or 8%, from December 31, 2017, driven by $1.6 billion of assets acquired through the Gibraltar acquisition and organic growth.

• Loans increased $2.3 billion, or 11%, in 2018, driven by $1.5 billion of loans acquired from Gibraltar and organic growth.

• Total deposits increased $1.7 billion, or 8%, in 2018, driven by $1.1 billion of deposits acquired from Gibraltar and organic growth.

• Asset quality and credit metrics improved as non-performing loans to total loans were 0.70% at September 30, 2018 compared to 0.76% at December 31, 2017. In addition, classified assets to total loans were 1.09% at September 30, 2018 compared to 1.45% at December 31, 2017.

• Shareholders’ equity increased $245.6 million, or 7%, from year-end 2017, primarily driven by the issuance of 2.8 million shares of common stock in March 2018 as part of consideration for the Gibraltar acquisition.

• On May 10, 2018, the Board of Directors of the Company authorized the repurchase of up to 1,137,500 shares of the Company's common stock. During the second and third quarters of 2018, the Company repurchased 763,210 common shares at a weighted average price of $79.99 per common share.

61

Outlook

2018 Financial Guidance:

On October 19, 2018, the Company announced the following updates to the previously provided financial guidance for 2018, as management narrows ranges as we begin fourth quarter. Management believes third quarter 2018 results are in-line with full year 2018 expectations.

The following further details management's expectations for 2018:

• Average earning assets of approximately $27.2 billion to $27.4 billion;

• Consolidated annualized loan growth of 12% to 13.5%;

• Consolidated annualized deposit growth of 9% to 10%;

• Provision expense of approximately $34 million to $37 million;

• Non-interest income, on a non-GAAP core basis, of approximately $198 million to $203 million;

• Non-interest expense, on a non-GAAP core basis, of approximately $682 million to $686 million;

• An effective tax rate of approximately 22% to 23%;

• Net interest margin of approximately 3.70% to 3.71%;

• Pre-tax one time charges of approximately $41 million to $42 million; and

• Stable credit quality.

Management also noted the following additional details regarding the 2018 financial guidance:

• Pre-tax one time charges were updated to include the previously announced 2018 branch closures;

• The updated 2018 financial guidance above assumes one additional federal funds rate increases in late 2018;

• Management anticipates share repurchases of approximately $30 million to $35 million for the fourth quarter of 2018; and

• The expected effective tax rate for the year excludes the income tax effects of merger and other pre-tax non-core adjustments, as well as other income tax adjustments.

Fourth Quarter 2018 Special Items:

• In connection with filing its 2017 income tax returns, the Company anticipates recognizing a non-core, permanent net income tax benefit of approximately $55 million in the fourth quarter of 2018. This anticipated benefit is based on the repricing of its current and deferred income tax position associated with the Tax Act following the filing of the Company’s remaining state income tax returns and the receipt of written consent from the IRS on a tax accounting method change.  The Company expects these items to be finalized in the fourth quarter of 2018.

62

2020 Strategic Goals:

In addition, on April 19, 2018, the Company announced its 2020 Strategic Goals, which provide financial and operating targets for Company performance to meet or exceed by the end of 2020.

The 2020 Strategic Goals are as follows:

• Core EPS growth of greater than 10%;

• Core Return on Average Assets of greater than 1.30%;

• Core Return on Average Tangible Common Equity of greater than 15%; and

• Core Tangible Efficiency Ratio of less than 55%.

See the Non-GAAP measures section of Management's Discussion and Analysis for a discussion of how non-GAAP core measures differ from GAAP, and how management uses these non-GAAP measures.

ANALYSIS OF RESULTS OF OPERATIONS

Net Interest Income/Net Interest margin

Net interest income is the difference between interest realized on earning assets and interest paid on interest-bearing liabilities and is also the largest driver of earnings. As such, it is subject to constant scrutiny by management. The rate of return and relative risk associated with earning assets are weighed to determine the appropriateness and mix of earning assets. Additionally, the need for lower cost funding sources is weighed against relationships with clients and future growth opportunities. The Company’s net interest spread, which is the difference between the yields earned on average earning assets and the rates paid on average interest-bearing liabilities, was 3.37% and 3.42%, during the three months ended September 30, 2018 and 2017, respectively, and 3.40% and 3.41% for the nine months ended September 30, 2018 and 2017, respectively. The Company’s net interest margin on a taxable equivalent (“TE”) basis, which is net interest income (TE) as a percentage of average earning assets, was 3.74% and 3.64%, respectively, for the three months ended September 30, 2018 and 2017, and 3.72% and 3.63% respectively, for the nine months ended September 30, 2018 and 2017.

65

The following table sets forth information regarding (i) the total dollar amount of interest income from earning assets and the resultant average yields; (ii) the total dollar amount of interest expense on interest-bearing liabilities and the resultant average rates; (iii) net interest income; (iv) net interest spread; and (v) net interest margin. Information is based on average daily balances during the indicated periods. Investment security market value adjustments and trade-date accounting adjustments are not considered to be earning assets and, as such, the net effect of these adjustments is included in non-earning assets.

Net interest income increased $42.3 million to $259.2 million in the third quarter of 2018 when compared to the same quarter of 2017. Volume changes contributed to 85% of this increase and 15% of the increase was driven by changes in rates. The primarily volume-driven increase in net interest income for the third quarter of 2018 is the result of a $3.8 billion, or 16%, increase in average earning assets, primarily due to the Sabadell United and Gibraltar acquisitions, and a 43 basis points, or 10%, increase in earning asset yield. This increase is partially offset by a $2.6 billion, or 16%, increase in average interest-bearing liabilities compared to the third quarter of 2017, and a 48 basis points, or 67%, increase in associated costs. The total cost of funding in the third quarter of 2018 was 89 basis points, compared to 54 basis points in the third quarter of 2017. The net interest margin on a tax-equivalent basis increased 10 basis points to 3.74% from 3.64% when comparing the periods.

Net interest income increased $174.9 million to $748.2 million in the nine months of 2018 when compared to the same period of 2017. Volume changes contributed to 89% of this increase while 11% was rate-driven. The primarily volume-driven increase in net interest income for the first nine months of 2018 is the result of a $5.6 billion, or 26%, increase in average earning assets, primarily due to the Sabadell United and Gibraltar acquisitions, and a 36 basis points, or 9%, increase in earning asset yield. This increase was partially offset by a $4.2 billion, or 29%, increase in average interest-bearing liabilities compared to the first nine months of 2017, and a 37 basis points, or 56%, increase in associated costs. The total cost of funding in the first nine months of 2018 was 76 basis points, compared to 48 basis points in the same period of 2017. Net interest margin on a tax-equivalent basis increased 9 basis points to 3.72% from 3.63% when comparing the periods. See Table 4 below for additional information regarding the changes in net interest income.

Average loans made up 80% and 77% of average earning assets in the third quarters of 2018 and 2017, respectively, and 79% and 76% for the first nine months of 2018 and 2017, respectively. Average loans increased $3.8 billion when comparing the third quarters of 2018 and 2017, and increased $5.2 billion when comparing the nine months ended September 30, 2018 and 2017. The associated taxable-equivalent yield increased 36 basis points when comparing the third quarters of 2018 and 2017, and increased 27 basis points when comparing the nine months ended September 30, 2018 and 2017. The increase in average loans was primarily attributable to the $4.0 billion and $1.5 billion in loans acquired through the Sabadell United and Gibraltar acquisitions, respectively, as well as growth within the legacy loan portfolio. The increases in the average loan yields were primarily driven by the repricing of variable rate legacy loans and origination coupons above existing portfolio rates. Average investment securities increased $0.3 billion when compared to the same quarter of 2017 and increased $0.8 billion when compared to the nine months ended September 30, 2017, driven by improved purchase yields within the investment securities portfolio.

Average interest-bearing deposits made up 87% and 86% of average interest-bearing liabilities in the third quarters of 2018 and 2017, respectively, and 87% and 90% for the nine months ended September 30, 2018 and 2017, respectively. The average balance of interest-bearing deposits increased $2.4 billion when comparing the third quarters of 2018 and 2017, and increased $3.2 billion when comparing the nine months ended September 30, 2018 and 2017, primarily related to the Sabadell United and Gibraltar acquisitions. The rate paid for interest-bearing deposits increased by 45 basis points when comparing the third quarters of 2018 and 2017, and increased 33 basis points when comparing the first nine months of 2018 and 2017. The total cost of interest-bearing liabilities increased 48 basis points when comparing the third quarters of 2018 and 2017, and increased 37 basis points when comparing the first nine months of 2018 and 2017. In addition to the impact of higher core deposits from recent acquisitions, the total cost of interest-bearing liabilities rose due to an upward repricing of deposits, higher yields on promotional deposit offerings, greater reliance on brokered wholesale CD funding, and increases in the average rate paid on short-term and long-term FHLB advances.

The increases in both earning asset yields and funding costs were impacted by the FOMC's interest rate increases of 25 basis points in December 2017, March 2018, June 2018, and September 2018.

The following table displays the dollar amount of changes in interest income and interest expense for major components of earning assets and interest-bearing liabilities. The table distinguishes between (i) changes attributable to volume (changes in average volume between periods times the average yield/rate for the two periods), (ii) changes attributable to rate (changes in average rate between periods times the average volume for the two periods), and (iii) total increase (decrease). Changes attributable to both volume and rate are allocated ratably between the volume and rate categories.

Provision for Loan and Lease Losses

The provision for loan and lease losses represents the expense necessary to maintain the ALLL at a level that in management's judgment is appropriate to absorb probable losses inherent in the portfolio at the balance sheet date.

The provision for loan and lease losses totaled $11.1 million for the third quarter of 2018, a $7.4 million, or 40%, decrease compared to the same period in 2017. The provision for loan and lease losses totaled $26.7 million for the first nine months of 2018, a $10.0 million, or 27%, decrease compared to the same period in 2017. The decrease in the provision for loan and lease losses was primarily due to an improvement in asset quality, as both non-performing loans and classified loans as a percentage of total loans declined when compared to 2017. In addition, net charge-offs were lower than in 2017. The Company's provision in 2018 was also limited by asset resolutions and cash flow events on acquired loans that reduced the required ALLL for that portfolio.

Refer to the "Asset Quality" section for further discussion on past due loans, non-performing assets, troubled debt restructurings and the allowance for credit losses.

69

Non-interest Income

Non-interest income totaled $53.1 million for the three months ended September 30, 2018, a $2.2 million increase compared to the same period of 2017. Increases in non-interest income during the quarter included $1.3 million in trust department income, $1.0 million in service charges on deposit accounts, and $0.6 million in title revenue, which were primarily driven by recent acquisitions. In addition, swap commissions increased $1.1 million due to an increase in client derivative activity. These increases were partially offset by a $3.3 million decrease in mortgage income, resulting from a $132.0 million decline in originations and a $97.0 million decrease in sales volume. An unfavorable fair value adjustment on mortgage loans held for sale, which are accounted for under the fair value option, also impacted mortgage income during the third quarter of 2018.

Non-interest income totaled $151.6 million for the nine months ended September 30, 2018, a $1.8 million increase compared to the same period of 2017. Increases in non-interest income during the first nine months of 2018 included $5.0 million in trust department income, $4.3 million in service charges on deposit accounts, $1.6 million in title revenue and $1.5 million in credit card and merchant-related income, which were primarily driven by recent acquisitions. In addition, swap commissions increased other non-interest income by $2.2 million due to an increase in client derivative activity. These increases were partially offset by a $13.8 million decrease in mortgage income, resulting from a $276.3 million decline in originations and a $214.1 million decrease in sales volume. The Company's focus on originating mortgage loans held for sale has partially shifted with a mix of new products that entered the portfolio in 2017 and 2018. Mortgage income was also negatively impacted by unfavorable fair value adjustments compared to the first nine months of 2017.

Non-interest Expense

The Company’s results for the third quarter of 2018 included non-interest expense of $169.3 million, a decrease of $31.4 million compared to the same quarter of 2017, largely due to Sabadell United-related merger, conversion, compensation and professional services expenses incurred during the third quarter of 2017. For the quarter, the Company’s efficiency ratio was 54.2%, compared to 75.0% in the third quarter of 2017.

Professional services decreased $17.0 million, or 76%, in the third quarter of 2018 when compared to the same period of 2017, primarily due to $11.6 million of merger-related legal and professional expenses as a result of the Sabadell United acquisition, as well as a $5.7 million HUD litigation accrual recorded in the third quarter of 2017.

Salaries and employee benefits decreased $5.8 million in the third quarter of 2018 when compared to the same period of 2017. Severance, retention, and other merger-related compensation expenses decreased $4.7 million, primarily driven by the Sabadell United acquisition during the third quarter of 2017. Full-time equivalent employees decreased 217 over that period, driven by efficiency initiatives, which decreased compensation and related benefits expenses. Merit raises, off cycle pay increases, and incentive expenses partially offset the favorable variations between periods.

The following expenses also drove the decrease in non-interest expense in the third quarter of 2018 compared to the third quarter of 2017:

• Errors, fines, and losses decreased $4.2 million, primarily due to the gain recognized in the third quarter of 2018 on the early termination of loss share agreements acquired through the Sabadell United acquisition;

• Data processing decreased $3.3 million; and

• Credit and other loan related expense decreased $2.4 million.

Non-interest expense for the first nine months of 2018 increased $69.6 million to $554.5 million, when compared to the first nine months of 2017, primarily driven by merger and compensation-related expenses from acquisition activity.

Salaries and employee benefits increased $38.1 million in the first nine months of 2018 when compared to the same period of 2017, primarily related to associates brought over from the recent acquisitions, which increased compensation and related benefits expenses. Severance, retention, and other merger-related compensation expenses increased $6.9 million, primarily driven by the Gibraltar acquisition. Also, in the first quarter of 2018, the Company rewarded certain associates a one-time cash bonus following the enactment of tax reform legislation, increasing bonus expense by $2.3 million. In addition, merit raises, off cycle pay increases, incentive expense, and restricted stock grants contributed to the increase in salaries and employee benefits between the periods.

70

The following acquisition-related expenses also drove the increase in non-interest expense in the first nine months of 2018 compared to the same period of 2017:

• Errors, fines, and losses increased $17.0 million, primarily due to branch consolidations/closures;

• Amortization of acquisition intangibles increased $8.6 million;

• Net occupancy and equipment increased $7.4 million, primarily due to acquired locations;

• Data processing increased $5.4 million, primarily conversion related; and

• Insurance expenses increased $5.3 million, due to an increase in FDIC Deposit Insurance premiums.

These increases in non-interest expense were offset by a decrease in professional services of $19.0 million. The decrease was primarily driven by the $11.7 million HUD litigation accrual recorded in the first nine months of 2017. The remaining decrease was due to merger-related legal expenses incurred during the acquisition of Sabadell United in the third quarter of 2017.

Income Taxes

For the three months ended September 30, 2018 and 2017, the Company recorded income tax expense of $30.4 million and $18.8 million, respectively, which resulted in an effective income tax rate of 23.1% and 38.8%, respectively. For the nine months ended September 30, 2018 and 2017, the Company recorded income tax expense of $78.4 million and $69.4 million, respectively, which resulted in an effective income tax rate of 24.6% for the first nine months of 2018 and 34.4% for the same period of 2017. The decrease in the effective income tax rate is primarily related to the reduction of the corporate income tax rate from 35% to 21%, effective January 1, 2018.

The difference between the Company's effective tax rate for the three and nine months ended September 30, 2018 and 2017 and the U.S. statutory tax rates of 21% and 35%, respectively, primarily relates to tax-exempt income, non-deductible expenses, state income taxes (net of federal income tax benefit), and the recognition of tax credits. The effective tax rate may vary significantly due to fluctuations in the amount and source of pretax income, changes in amounts of non-deductible expenses, and timing of the recognition of tax credits. In addition, the difference between the Company's effective tax rate for the nine months ended September 30, 2018 and the U.S. statutory tax rate of 21% primarily relates to the discrete item of $6.6 million in income tax expense due to the write-down of deferred tax assets in the second quarter of 2018 associated with the finalization of the accounting for the Sabadell United acquisition and the related impact of the Tax Act on those adjustments. This adjustment increased the effective tax rate for the nine months ended September 30, 2018 by 2.1% from 22.5% to 24.6%.

FINANCIAL CONDITION

The following discussion highlights the Company’s major categories of earning assets.

Loans and Leases

The Company had total loans and leases of $22.3 billion at September 30, 2018, an increase of $2.3 billion from December 31, 2017. The increase was a result of $1.5 billion acquired in the first quarter of 2018 from Gibraltar and legacy loan growth of $1.9 billion, offset by pay-downs and pay-offs on loans, primarily from prior period acquisitions.

The Company’s loan to deposit ratio was 96% at September 30, 2018 and 94% at December 31, 2017. The percentage of fixed-rate loans to total loans was 40% at September 30, 2018 compared to 41% at the end of 2017.

71

The major categories of loans and leases outstanding at September 30, 2018 and December 31, 2017 are presented in the following table.

Loan Portfolio Components

The Company believes its loan portfolio is diversified by product and geography throughout its footprint. With the Gibraltar acquisition, the Company added $1.5 billion of loans and expanded its presence in Southeast Florida and entered New York. Excluding acquired loans, loan growth thus far in 2018 was strongest in the the Energy Group (reserve-based lending), Corporate Asset Finance division (equipment financing business), and the New Orleans and Atlanta markets. Loans in the Energy Group increased $316.6 million, or 73% since December 31, 2017. The Corporate Asset Finance division, which was created in 2017, grew loans and leases $199.8 million, or 74%, thus far in 2018. The New Orleans and Atlanta markets had growth of $155.0 million and $102.9 million, respectively, in the first nine months of 2018.

Commercial Loans

Total commercial loans and leases increased $889.6 million, or 6%, from December 31, 2017. Commercial loans and leases decreased to 67% of the total portfolio at September 30, 2018 compared to 70% at December 31, 2017, primarily due to a mix-shift from the acquisition of a relatively large residential mortgage portfolio from Gibraltar. Unfunded commitments on commercial loans including approved loan commitments not yet funded were $5.9 billion at September 30, 2018, an increase of $869.9 million, or 17%, when compared to the end of the prior year.

Commercial real estate loans include loans to commercial customers for long-term financing of land and buildings or for land development or construction of a building. These loans are repaid from revenues through operations of the businesses, rents of properties, sales of properties and refinances. The Company’s underwriting standards generally provide for loan terms of three to seven years, with amortization schedules of generally no more than twenty-five years. Low loan-to-value ratios are generally maintained and usually limited to no more than 80% at the time of origination. The commercial real estate portfolio is comprised of approximately 12% construction loans, 26% owner-occupied loans, and 62% non-owner-occupied loans as of September 30, 2018, relatively consistent with 14%, 27%, and 59%, respectively, at December 31, 2017. Commercial real estate loans increased $443.7 million, or 5%, during the first nine months of 2018, primarily from $292.5 million acquired from Gibraltar.

72

Commercial and industrial loans and leases represent loans to commercial customers to finance general working capital needs, equipment purchases and leases and other projects where repayment is derived from cash flows resulting from business operations. The Company originates commercial business loans on a secured and, to a lesser extent, unsecured basis. The Company’s commercial business loans may be term loans or revolving lines of credit. Term loans are generally structured with terms of no more than three to seven years, with amortization schedules of generally no more than fifteen years. Commercial business term loans are generally secured by equipment, machinery or other corporate assets. The Company also provides for revolving lines of credit generally structured as advances upon perfected security interests in accounts receivable and inventory. Revolving lines of credit generally have annual maturities. The Company obtains personal guarantees of the principals as additional security for most commercial business loans. As of September 30, 2018, commercial and industrial loans and leases totaled $5.6 billion, a $446.0 million, or 9% increase, from December 31, 2017, which includes approximately $43.1 million in loans acquired from Gibraltar. Commercial and industrial loans and leases comprised 25% of the total portfolio at September 30, 2018 and 26% at December 31, 2017.

The following table details the Company’s commercial loans and leases by state.

⁽¹⁾  Other loans include primarily equipment financing and corporate asset financing leases, which the Company does not classify by state.

Residential Mortgage Loans

Residential mortgage loans consist of loans to consumers to finance a primary residence. The residential mortgage loan portfolio is comprised of non-conforming 1-4 family mortgage loans secured by properties located in the Company's market areas and originated under terms and documentation that permit their sale in a secondary market, as well as larger mortgage loans of current and prospective private banking clients. These mortgage loans are generally retained to enhance relationships, but also tend to be more profitable due to the expected shorter durations and relatively lower servicing costs associated with loans of this size. The Company does not originate or hold high loan-to-value, negative amortization, option ARM, or other exotic mortgage loans in its portfolio. The Company makes insignificant investments in loans that would be considered sub-prime (e.g., loans with a credit score of less than 620) in order to facilitate compliance with relevant Community Reinvestment Act regulations.

Total residential mortgage loans increased $1.2 billion, or 41%, compared to December 31, 2017, primarily the result of approximately $929.6 million in acquired Gibraltar residential mortgage loans.

Consumer and Other Loans

The Company offers consumer loans in order to provide a full range of retail financial services to customers in the communities in which it operates. The Company originates substantially all of its consumer loans in its primary market areas. At September 30, 2018, $3.1 billion, or 14%, of the total loan portfolio was comprised of consumer loans, compared to $2.9 billion, or 15%, at the end of 2017.

73

The majority of the consumer loan portfolio is comprised of home equity loans. Home equity lending allows customers to borrow against the equity in their home and is secured by a first or second mortgage on the borrower’s residence. Real estate market values at the time the loan is secured affect the amount of credit extended. Changes in these values may impact the extent of potential losses. Home equity loans were $2.4 billion at September 30, 2018, an increase of $57.9 million from December 31, 2017. Unfunded commitments related to home equity loans and lines were $1.0 billion at September 30, 2018, an increase of $126.0 million, or 14%, from the end of 2017.

All other consumer loans, which consist of credit card loans, automobile loans and other personal loans, increased $74.4 million, or 11%, from December 31, 2017, primarily from an increase of $119.1 million in other personal loans, $24.9 million of which was acquired from Gibraltar, partially offset by a decrease in indirect automobile loans, a product that is no longer offered.

In order to assess the risk characteristics of the loan portfolio, the Company considers the current U.S. economic environment and that of its primary market areas. See Note 6, Allowance for Credit Losses, to the unaudited consolidated financial statements for credit quality factors by loan portfolio segment.

Additional information on the Company’s consumer loan portfolio is presented in the following tables. For the purposes of Table 7, unscoreable consumer loans have been included with loans with credit scores below 660. Credit scores reflect the most recent information available as of the dates indicated.

Mortgage Loans Held for Sale

The Company continues to sell the majority of conforming mortgage loan originations in the secondary market rather than assume the interest rate risk associated with these longer term assets. Upon the sale, the Company retains servicing on a limited portion of these loans. Loans held for sale totaled $43.0 million at September 30, 2018, a decrease of $91.9 million, or 68%, from $134.9 million at year-end 2017, as sales activity has outpaced originations during the first three quarters of 2018. Origination and sales volumes have decreased from the comparable 2017 period from reduced activity due to higher interest rates.

74

Loans held for sale have primarily been fixed-rate single-family residential mortgage loans under contracts to be sold in the secondary market. In most cases, loans in this category are sold within thirty days of closing. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances. See Note 1, Summary of Significant Accounting Policies, in the Annual Report on Form 10-K for the year ended December 31, 2017, for further discussion.

Investment Securities

Investment securities increased $30.3 million, or 1%, since December 31, 2017 to $4.8 billion at September 30, 2018, primarily due to purchases of investment securities, partially offset by an unfavorable market valuation on available for sale securities. Approximately 96% of the Company's investment portfolio is in available for sale securities, which experience unrealized losses as interest rates rise. Investment securities approximated 16% and 17% of total assets at September 30, 2018 and December 31, 2017, respectively.

All of the Company's mortgage-backed securities were issued by government-sponsored enterprises at September 30, 2018 and December 31, 2017. The Company does not hold any Fannie Mae or Freddie Mac preferred stock, corporate equity, collateralized debt obligations, collateralized loan obligations, or structured investment vehicles, nor does it hold any private label collateralized mortgage obligations, subprime, Alt-A, sovereign debt, or second lien elements in its investment portfolio. At September 30, 2018 and December 31, 2017, the Company's investment portfolio did not contain any securities that are directly backed by subprime or Alt-A mortgages.

Funds generated as a result of sales and prepayments of investment securities are used to fund loan growth and purchase other securities. The Company continues to monitor market conditions and take advantage of market opportunities with appropriate risk and return elements.

Short-term Investments

Short-term investments primarily result from excess funds invested overnight in interest-bearing deposit accounts at the FRB and the FHLB of Dallas. These balances fluctuate daily depending on the funding needs of the Company and earn interest at the current FRB and FHLB discount rates. The balance in interest-bearing deposits at other institutions decreased $121.7 million, or 40%, from December 31, 2017 to $184.9 million at September 30, 2018, primarily due to deposit decreases and net loan growth. The Company’s cash activity is further discussed in the “Liquidity and Other Off-Balance Sheet Activities” section below.

Asset Quality

The lending activities of the Company are governed by underwriting policies established by management and approved by the Board Risk Committee of the Board of Directors. Commercial risk personnel, in conjunction with senior lending personnel, underwrite the vast majority of commercial loans. The Company provides centralized underwriting of substantially all residential mortgage, small business and consumer loans. Established loan origination procedures require appropriate documentation, including financial data and credit reports. For loans and leases secured by real property, the Company generally requires property appraisals, title insurance or a title opinion, hazard insurance, and flood insurance, where appropriate.

Loan payment performance is monitored and late charges are generally assessed on past due accounts. Delinquent and problem loans are administered by functional teams of specialized risk officers. Risk ratings on commercial exposures (as described below) are reviewed on an ongoing basis and are adjusted as necessary based on the obligor’s risk profile and debt capacity. The loan review department is responsible for independently assessing and validating risk ratings assigned to commercial exposures through a periodic sampling process.All other loans are also subject to loan reviews through a similar periodic sampling process.

The Company utilizes an asset risk classification system in accordance with guidelines established by the FRB as part of its efforts to monitor commercial asset quality. In connection with their examinations of insured institutions, both federal and state examiners also have the authority to identify problem assets and, if appropriate, reclassify them. There are three classifications for problem assets: “substandard,” “doubtful,” and “loss”, all of which are considered adverse classifications. Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the weaknesses are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full questionable, and there is a high probability of loss based on currently existing facts, conditions and values. An asset classified as loss is considered not collectible and of such little value that continuance as an asset of the Company is not warranted. The Company exercises judgment in determining the risk classification of its commercial exposures.

75

Commercial loans are placed on non-accrual status when any of the following occur: 1) the loan is maintained on a cash basis because of deterioration in the financial condition of the borrower; 2) collection of the full contractual amount of principal or interest is not expected (even if the loan is currently paying as agreed); or 3) when principal or interest has been in default for a period of 90 days or more, unless the loan is both well secured and in the process of collection. Factors considered in determining the collection of the full contractual amount of principal or interest include assessment of the borrower’s cash flow, valuation of underlying collateral, and the ability and willingness of guarantors to provide credit support.  Certain commercial loans are also placed on non-accrual status when payment is not past due and full payment of principal and interest is expected, but there is doubt about the borrower’s ability to comply with existing repayment terms. Consideration will be given to placing a loan on non-accrual due to the deterioration of the debtor’s repayment ability, the repayment of the loan becoming dependent on the liquidation of collateral, an existing collateral deficiency, the loan being classified as "doubtful" or "loss", the client filing for bankruptcy, and/or foreclosure being initiated. Regarding all classes within the C&I and CRE portfolios, the determination of a borrower’s ability to make the required principal and interest payments is based on an examination of the borrower’s current financial statements, industry, management capabilities, and other qualitative factors.

When a loan is placed on non-accrual status, the accrual of interest income ceases and accrued but unpaid interest is generally reversed against interest income.

Real estate acquired by the Company through foreclosure or by deed-in-lieu of foreclosure is classified as OREO, and is recorded at the lesser of the related loan balance (the pro-rata carrying value for acquired loans) or estimated fair value less costs to sell. Closed bank branches are also classified as OREO and recorded at the lower of cost or market value.

Under GAAP, certain loan modifications or restructurings are designated as TDRs. In general, the modification or restructuring of a debt constitutes a TDR if the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider under current market conditions. See Note 1, Summary of Significant Accounting Policies, in the 2017 10-K for further details.

Non-performing Assets

The Company defines non-performing assets as non-accrual loans, accruing loans more than 90 days past due, OREO, and foreclosed property. Management continuously monitors and transfers loans to non-accrual status when warranted.

The Company accounts for loans currently or formerly covered by loss sharing agreements with the FDIC, other loans acquired with deteriorated credit quality, as well as all loans acquired with significant discounts that did not exhibit deteriorated credit quality at acquisition, in accordance with ASC Topic 310-30. Collectively, all loans accounted for under ASC 310-30 are referred to as "acquired impaired loans." Application of ASC Topic 310-30 results in significant accounting differences, compared to loans originated or acquired by the Company that are not accounted for under ASC 310-30. See Note 1, Summary of Significant Accounting Policies, in the 2017 10-K for further details.

Due to the significant difference in accounting for acquired impaired loans, the Company believes inclusion of these loans in certain asset quality ratios that reflect non-performing assets in the numerator or denominator (or both) results in significant distortion to these ratios. In addition, because loan-level charge-offs related to acquired impaired loans are not recognized in the financial statements until the cumulative amounts exceed the original loss projections on a pool basis, the net charge-off ratio for acquired loans is not consistent with the net charge-off ratio for other loan portfolios. The inclusion of these loans in certain asset quality ratios could result in a lack of comparability across quarters or years, and could impact comparability with other portfolios that were not impacted by acquired impaired loan accounting. The Company believes that the presentation of certain asset quality measures excluding acquired impaired loans, as indicated below, and related amounts from both the numerator and denominator provides better perspective into underlying trends related to the quality of its loan portfolio. Accordingly, the asset quality measures in the tables below present asset quality information excluding acquired impaired loans, as indicated within each table, and related amounts.

76

The following table sets forth the composition of the Company’s non-performing assets and TDRs for the periods indicated.

⁽¹⁾  Non-performing loans and non-performing assets include accruing loans 90 days or more past due.

⁽²⁾  OREO and foreclosed property at September 30, 2018 and December 31, 2017 include $13.9 million and $4.5 million, respectively, of former bank properties held for development or resale.

⁽³⁾  Performing troubled debt restructurings for September 30, 2018 and December 31, 2017 exclude $69.7 million and $68.5 million, respectively, in troubled debt restructurings that meet non-performing asset criteria.

⁽⁴⁾  Non-performing loans exclude acquired impaired loans, even if contractually past due or if the Company does not expect to receive payment in full, as the Company is currently accreting interest income over the expected life of the loans.

Total non-performing assets increased $9.6 million, or 5%, compared to December 31, 2017, as non-performing loans and leases increased $3.8 million and OREO and foreclosed property increased $5.9 million. Former bank properties increased $9.4 million in 2018 as branches closed were moved out of service and into former bank properties. The increase was partially offset by the sale of OREO properties during the year. Non-performing loans and leases increased 2% driven by an increase in accruing loans past due more than 90 days, which was a result of a limited number of credits moving to past due. The decrease in non-accrual loans was primarily related to payments and charge-offs of non-accrual loans since December 31, 2017.

Non-performing loans were 0.70% of total loans at September 30, 2018, six basis points lower than at December 31, 2017. Total non-performing assets were 0.63% of total assets at September 30, 2018, one basis point lower than December 31, 2017. Including TDRs that are in compliance with their modified terms, total non-performing assets and TDRs decreased $0.8 million during the first nine months of 2018.

At September 30, 2018, the Company had $196.1 million of commercial assets classified as substandard and $35.5 million of commercial assets classified as doubtful. Accordingly, the aggregate of the Company’s classified commercial assets was $231.6 million, or 0.78% of assets and 1.55% of total commercial loans. At December 31, 2017, classified commercial assets totaled $298.5 million, or 1.07% of assets and 2.12% of total commercial loans. The $66.9 million decrease in commercial classified assets over the past nine months is primarily due to payments on these classified assets.

In addition to the problem loans described above, there were $196.0 million of commercial loans classified as special mention at September 30, 2018. Special mention loans are defined as loans with potential weaknesses that may, if not corrected, result in future deterioration of the loan. Special mention loans were 1.31% of total commercial loans at September 30, 2018 and 1.49% at December 31, 2017. Special mention loans at September 30, 2018 decreased $13.9 million, or 7%, from December 31, 2017, primarily from upgrades to a limited number of customer relationships during the first three quarters of 2018.

77

Past Due and Non-accrual Loans

Past due status is based on the contractual terms of loans. Total past due and non-accrual loans were 1.01% of total loans and leases at September 30, 2018 compared to 1.07% at December 31, 2017. Additional information on past due loans and leases is presented in the following table.

⁽¹⁾  Past due and non-accrual loan amounts exclude acquired impaired loans, even if contractually past due or if the Company does not expect to receive payment in full, as the Company is currently accreting interest income over the expected life of the loans.

Total past due and non-accrual loans increased $12.7 million from December 31, 2017 to $226.7 million at September 30, 2018. The change was due to a $14.5 million increase in accruing past due loans, offset by a decrease of $1.8 million in non-accrual loans. The increase in accruing past due loans was primarily a result of a limited number of commercial credits that moved past due at September 30, 2018. Of the total accruing past due loans, 46% were past due less than 60 days (compared to 54% at December 31, 2017), and 85% were past due less than 90 days (compared to 90% at year-end 2017).

Allowance for Credit Losses

The allowance for credit losses represents management’s best estimate of probable credit losses inherent at the balance sheet date. Determination of the allowance for credit losses involves a high degree of complexity and requires significant judgment. Several factors are taken into consideration in the determination of the overall allowance for credit losses. Based on facts and circumstances available, management of the Company believes that the allowance for credit losses was appropriate at September 30, 2018 to cover probable losses in the Company’s loan portfolio. However, future adjustments to the allowance may be necessary, and the results of operations could be adversely affected, if circumstances differ substantially from the assumptions used by management in determining the allowance for credit losses. See the “Application of Critical Accounting Policies and Estimates” and Note 1, Summary of Significant Accounting Policies, in the Annual Report on Form 10-K for the year ended December 31, 2017 for more information.

78

The following table sets forth the activity in the Company’s allowance for credit losses for the nine-month periods ended September 30, 2018 and 2017.

TABLE 11—SUMMARY OF ACTIVITY IN THE ALLOWANCE FOR CREDIT LOSSES

(Dollars in thousands)	September 30, 2018			September 30, 2017

Reserve for unfunded lending commitments at end of period	14,721			21,032
Allowance for credit losses at end of period	$	151,671		$	157,660

The allowance for credit losses totaled $151.7 million at September 30, 2018, or 0.68% of total loans and leases, compared to $154.1 million, or 0.77% of total loans and leases, at December 31, 2017. The decrease in the allowance for credit losses as a percentage of loans and leases was primarily the result of the acquired Gibraltar loans, as those acquired loans are recorded at estimated fair value as of the acquisition date, which includes an estimate of expected losses in this portfolio, and as a result, no allowance for loan losses was established as of the acquisition date. Additionally, recoveries on acquired loans during 2018 reduced the required allowance for credit losses for that portfolio.

Net charge-offs during the third quarter of 2018 were $9.0 million, a decrease of $19.9 million from the comparable 2017 period. Net charge-offs were 0.16% of average loans and leases on an annualized basis for the third quarter of 2018 compared to 0.62% for the comparable 2017 period. The decrease in net charge-off percentage is due to both an increase in average loans and leases between periods and higher energy-related charge-offs in the third quarter of 2017 on a limited number of customer relationships.

Net charge-offs during the first nine months of 2018 were $24.9 million, or 0.16% of average loans and leases on an annualized basis, as compared to net charge-offs of $45.8 million, or 0.38% annualized, for the first nine months of 2017. The decline in net charge-offs was the result of a $15.2 million decrease in gross charge-offs and a $5.7 million increase in recoveries, primarily from one large commercial recovery of $3.3 million in 2018. The provision for loan and lease losses covered 107.1% and 80.2% of net charge-offs for the first nine months of 2018 and 2017, respectively.

At September 30, 2018 and December 31, 2017, the ALLL covered 87.8% and 92.5% of total non-performing loans, respectively.

Deposits, both those obtained from clients in its primary market areas and those acquired through acquisitions, are the Company’s principal source of funds for use in lending and other business purposes. The Company attracts local deposit accounts by offering a wide variety of products, competitive interest rates and convenient branch office locations and service hours, as well as on-line banking services at www.iberiabank.com and www.virtualbank.com. Increasing core deposits is a continuing focus of the Company and has been accomplished through the development of client relationships and acquisitions. Short-term and long-term borrowings are also important funding sources for the Company. Other funding sources include subordinated debt and shareholders’ equity. Refer to the “Liquidity and Other Off-Balance Sheet Activities” section below for further discussion of the Company’s sources and uses of funding. The following discussion highlights the major changes in the mix of deposits and other funding sources during the first nine months of 2018.

79

Deposits

The Company’s ability to attract and retain customer deposits is critical to the Company’s continued success. Total deposits increased $1.7 billion, or 8%, to $23.2 billion at September 30, 2018, from $21.5 billion at December 31, 2017, driven by $1.1 billion of deposits acquired from Gibraltar in March of 2018 and organic growth. Excluding acquired deposits, deposit growth during 2018 was strongest in the Virtual Bank division (digital banking) and the Southwest Louisiana and Dallas markets.

The following table sets forth the composition of the Company’s deposits as of the dates indicated.

Short-term Borrowings

The Company may obtain advances from the FHLB of Dallas based upon its ownership of FHLB stock and certain pledges of its real estate loans and investment securities, provided certain standards related to the Company’s creditworthiness have been met. These advances are made pursuant to several credit programs, each of which has its own interest rate and range of maturities. The level of short-term borrowings can fluctuate significantly on a daily basis depending on funding needs and the source of funds chosen to satisfy those needs.

The Company also enters into repurchase agreements to facilitate customer transactions that are accounted for as secured borrowings. These transactions typically involve the receipt of deposits from customers that the Company collateralizes with its investment portfolio and have an average rate of 45.5 basis points.

Total short-term borrowings increased $251.4 million, or 25%, from December 31, 2017, to $1.2 billion at September 30, 2018. An increase of $315.0 million in outstanding short-term FHLB advances was partially offset by a decrease of $63.6 million in repurchase transactions. The increase in short-term FHLB advances was primarily due to additional advances made in the second and third quarters of 2018, causing the average rate on short-term borrowings to rise as maturing advances had lower rates.

On a quarter-to-date average basis, short-term borrowings decreased $423.1 million, or 26%, from the third quarter of 2017, mostly due to short-term borrowings that matured in the fourth quarter of 2017 and the first quarter of 2018, partially offset by additional short-term advances made in the second and third quarters of 2018.

Total short-term borrowings were 5% of total liabilities and 46% of total borrowings at September 30, 2018 compared to 4% and 40%, respectively, at December 31, 2017. On a quarter-to-date average basis, short-term borrowings were 5% of total liabilities and 46% of total borrowings in the third quarter of 2018, compared to 7% and 69%, respectively, during the same period of 2017.

Long-term Debt

Long-term debt decreased $29.0 million, or 2%, from December 31, 2017, to $1.5 billion at September 30, 2018, which included $405.1 million in acquired long-term FHLB advances from Gibraltar which was immediately paid off upon acquisition during the first quarter of 2018. The Company made an additional $956.3 million in repayments, partially offset by $922.0 million of long-term FHLB advances and $5.9 million of additional notes payable in the first nine months of 2018. On a period-end basis, long-term debt was 6% of total liabilities at September 30, 2018 and December 31, 2017.

On a quarter-to-date average basis, long-term debt increased to $1.4 billion in the third quarter of 2018, $638.2 million, or 86%, higher than the third quarter of 2017, primarily from additional long-term FHLB advances in the fourth quarter of 2017 to improve liquidity and to take advantage of attractive rates. Average long-term debt was 5% of average total liabilities during the third quarter of 2018 compared to 3% during the same period of 2017.

80

Long-term debt at September 30, 2018 included $1.3 billion in fixed-rate advances from the FHLB of Dallas that cannot be prepaid without incurring substantial penalties. The remaining debt consisted of $120.1 million of the Company’s junior subordinated debt and $50.0 million in notes payable on investments in new market tax credit entities. Interest on the junior subordinated debt is payable quarterly and may be deferred at any time at the election of the Company for up to 20 consecutive quarterly periods. During any deferral period, the Company is subject to certain restrictions, including being prohibited from declaring dividends to its common shareholders. The junior subordinated debt is redeemable by the Company in whole or in part.

CAPITAL RESOURCES

Common Stock

Shareholders' equity increased $245.6 million, or 7%, during the first three quarters of 2018, primarily from the Company's issuance of 2.8 million shares of common stock at a price of $77.00 per common share on March 23, 2018 as part of the Gibraltar acquisition. The net increase to equity from the offering was $214.7 million. See Note 10, Shareholders' Equity, Capital Ratios, and Other Regulatory Matters, to the unaudited consolidated financial statements for more information.

The increase in shareholders' equity was also a result of undistributed income to common shareholders of $167.8 million, but was negatively impacted by a $87.5 million decrease in accumulated other comprehensive income, primarily resulting from a lower valuation of the Company's available for sale investment securities from rising short-term interest rates.

In 2018, the Company's Board of Directors authorized a share repurchase program of up to 1,137,500 shares of IBERIABANK Corporation common stock. During the first nine months of 2018, the Company repurchased 763,210 common shares for $61.0 million at a weighted average cost of $79.99 per share, which included 335,000 common shares repurchased under a plan previously approved by the Board of Directors that has subsequently expired. At September 30, 2018, the remaining common shares that could be repurchased under the current Board-approved plan was 709,290 shares. Subsequent to September 30, 2018 and through November 5, 2018, the Company repurchased the remaining shares of common stock for approximately $52.6 million.

The Company's quarterly dividend to common shareholders was $0.39 per common share in the third quarter of 2018 compared to $0.37 in the third quarter of 2017. On a year-to-date basis, dividends paid to common shareholders of $1.15 is 6% higher than the $1.09 paid per common share for the nine-month period of 2017. The dividend payout ratio was 27.7% for the current year, down from 45.7% in the comparable period of 2017.

Regulatory Capital

Federal regulations impose minimum regulatory capital requirements on all institutions with deposits insured by the FDIC. The FRB imposes similar capital regulations on bank holding companies. Compliance with bank and bank holding company regulatory capital requirements, which include leverage and risk-based capital guidelines, are monitored by the Company on an ongoing basis. Under the risk-based capital method, a risk weight is assigned to balance sheet and off-balance sheet items based on regulatory guidelines.

At September 30, 2018 and December 31, 2017, the Company exceeded all required regulatory capital ratios, and the regulatory capital ratios of IBERIABANK were in excess of the levels established for “well-capitalized” institutions, as shown in the following table.

TABLE 13—REGULATORY CAPITAL RATIOS

Ratio	Entity	Well- Capitalized Minimums		September 30, 2018		December 31, 2017
				Actual		Actual
Tier 1 Leverage	IBERIABANK Corporation	N/A		9.65	%	9.35	%
	IBERIABANK	5.00	%	9.60		9.10
Common Equity Tier 1 (CET1)	IBERIABANK Corporation	N/A		10.79		10.57
	IBERIABANK	6.50	%	11.27		10.86
Tier 1 risk-based capital	IBERIABANK Corporation	N/A		11.33		11.16
	IBERIABANK	8.00	%	11.27		10.86
Total risk-based capital	IBERIABANK Corporation	N/A		12.42		12.37
	IBERIABANK	10.00	%	11.89		11.55

81

Minimum capital ratios are subject to a capital conservation buffer. In order to avoid limitations on distributions, including dividend payments, and certain discretionary bonus payments to executive officers, an institution must hold a capital conservation buffer above its minimum risk-based capital requirements. This capital conservation buffer is calculated as the lowest of the differences between the actual CET1 ratio, Tier 1 Risk-Based Capital Ratio, and Total Risk-Based Capital ratio and the corresponding minimum ratios. At September 30, 2018, the required minimum capital conservation buffer was 1.875%, which will increase by 0.625% and be fully phased-in on January 1, 2019 at 2.50%. At September 30, 2018, the capital conservation buffers of the Company and IBERIABANK were 4.42% and 3.89%, respectively. Management believes that at September 30, 2018, the Company and IBERIABANK would have met all capital adequacy requirements on a fully phased-in basis if such requirements were then effective.

Capital ratios at September 30, 2018 were impacted by the Gibraltar acquisition, as the common stock issued in 2018 resulted in an increase in the Company's risk-based capital ratios.

LIQUIDITY AND OTHER OFF-BALANCE SHEET ACTIVITIES

Liquidity refers to the Company’s ability to generate sufficient cash flows to support its operations and to meet its obligations, including the withdrawal of deposits by customers, commitments to originate loans, and its ability to repay its borrowings and other liabilities. Liquidity risk is the risk to earnings or capital resulting from the Company’s inability to fulfill its obligations as they become due. Liquidity risk also develops from the Company’s failure to timely recognize or address changes in market conditions that affect the ability to liquidate assets in a timely manner or to obtain adequate funding to continue to operate on a profitable basis.

The primary sources of funds for the Company are deposits and borrowings. Other sources of funds include repayments and maturities of loans and investment securities, securities sold under agreements to repurchase, and, to a lesser extent, off-balance sheet borrowing availability. Time deposits scheduled to mature in one year or less at September 30, 2018 totaled $2.0 billion. Based on past experience, management believes that a significant portion of maturing deposits will remain with the Company. Additionally, the majority of the investment securities portfolio is classified as available for sale, which provides the ability to liquidate unencumbered securities as needed. Of the $4.8 billion in the investment securities portfolio, $2.5 billion is unencumbered and $2.3 billion has been pledged to support repurchase transactions, public funds deposits and certain long-term borrowings. Due to the relatively short implied duration of the investment securities portfolio, the Company has historically experienced consistent cash inflows on a regular basis. Securities cash flows are highly dependent on prepayment speeds and could change materially as economic or market conditions change. 

Scheduled cash flows from the amortization and maturities of loans and securities are relatively predictable sources of funds. Conversely, deposit flows, prepayments of loan and investment securities, and draws on customer letters and lines of credit are greatly influenced by general interest rates, economic conditions, competition, and customer demand. The FHLB of Dallas provides an additional source of liquidity to make funds available for general requirements and to assist with the variability of less predictable funding sources. At September 30, 2018, the Company had $2.1 billion of outstanding FHLB advances, $790.0 million of which was short-term and $1.3 billion that was long-term. Additional FHLB borrowing capacity available at September 30, 2018 amounted to $7.1 billion. At September 30, 2018, the Company also had various funding arrangements with the Federal Reserve Bank's discount window and commercial banks providing up to $301.3 million in the form of federal funds and other lines of credit. At September 30, 2018, there were no balances outstanding on these lines and all of the funding was available to the Company.

Liquidity management is both a daily and long-term function of business management. The Company manages its liquidity with the objective of maintaining sufficient funds to respond to the predicted needs of depositors and borrowers and to take advantage of investments in earning assets and other earnings enhancement opportunities. Excess liquidity is generally invested in short-term investments such as overnight deposits. On a longer-term basis, the Company maintains a strategy of investing in various lending and investment security products. The Company uses its sources of funds primarily to fund loan commitments and to meet its ongoing commitments associated with its operations. Based on its available cash at September 30, 2018 and current deposit modeling, the Company believes it has adequate liquidity to fund ongoing operations. The Company has adequate availability of funds from deposits, borrowings, repayments and maturities of loans and investment securities to provide the Company additional working capital if needed.

82

ASSET/LIABILITY MANAGEMENT, MARKET RISK AND COUNTERPARTY CREDIT RISK

The principal objective of the Company’s asset and liability management function is to evaluate the Company's interest rate risk included in certain balance sheet accounts, determine the appropriate level of risk given the Company’s business focus, operating environment, capital and liquidity requirements, and performance objectives, establish prudent asset concentration guidelines and manage the risk consistent with Board approved guidelines. Through such management, the Company seeks to reduce the vulnerability of its operations to changes in interest rates. The Company’s actions in this regard are taken under the guidance of the Asset and Liability Committee. The Asset and Liability Committee normally meets monthly to review, among other things, the sensitivity of the Company’s assets and liabilities to interest rate changes, local and national market conditions, and interest rates. In connection therewith, the Asset and Liability Committee generally reviews the Company’s liquidity, cash flow needs, composition of investments, deposits, borrowings, and capital position.

The objective of interest rate risk management is to control the effects that interest rate fluctuations have on net interest income and on the net present value of the Company’s earning assets and interest-bearing liabilities. Management and the Board are responsible for managing interest rate risk and employing risk management policies that monitor and limit this exposure. Interest rate risk is measured using net interest income simulation and asset/liability net present value sensitivity analyses. The Company uses financial modeling to measure the impact of changes in interest rates on the net interest margin and to predict market risk. Estimates are based upon numerous assumptions including the nature and timing of interest rate levels including yield curve shape, prepayments on loans and securities, deposit decay rates, pricing decisions on loans and deposits, reinvestment/replacement of asset and liability cash flows, and others. These analyses provide a range of potential impacts on net interest income and portfolio equity caused by interest rate movements.

Included in the modeling are instantaneous parallel rate shift scenarios, which are utilized to establish exposure limits. These scenarios are known as “rate shocks” because all rates are modeled to change instantaneously by the indicated shock amount, rather than a gradual rate shift over a period of time.

The Company’s interest rate risk model indicates that the Company is asset sensitive in terms of net interest income sensitivity. Based on the Company’s interest rate risk model at September 30, 2018, the table below illustrates the impact of an immediate and sustained 100 and 200 basis points increase or decrease in interest rates on net interest income over the next twelve months.

TABLE 14—INTEREST RATE SENSITIVITY

Shift in Interest Rates (in bps)	% Change in Projected Net Interest Income
+200	+1.8%
+100	+1.1%
-100	(3.4)%
-200	(10.6)%

The influence of using the forward curve as of September 30, 2018 as a basis for projecting the interest rate environment would approximate a 0.8% increase in net interest income over the next 12 months. The computations of interest rate risk shown above are performed on a static balance sheet and do not necessarily include certain actions that management may undertake to manage this risk in response to unanticipated changes in interest rates and other factors to include shifts in deposit behavior.

The short-term interest rate environment is primarily a function of the monetary policy of the FRB. The principal tools of the FRB for implementing monetary policy are open market operations, or the purchases and sales of U.S. Treasury and Federal agency securities, as well as the establishment of a short-term target rate. The FRB’s objective for open market operations has varied over the years, but the focus has gradually shifted toward attaining a specified level of the Federal funds rate to achieve the long-run goals of price stability and sustainable economic growth. The Federal funds rate is the basis for overnight funding and drives the short end of the yield curve. Longer maturities are influenced by the market’s expectations for economic growth and inflation, but can also be influenced by FRB purchases and sales and expectations of monetary policy going forward.

83

On September 27, 2018, the Federal Open Market Committee (“FOMC”) voted to raise the target federal funds rate by 0.25% to a range of 2.00%-2.25%. The FOMC has now raised rates by two percentage points since the financial crisis in 2008, a sign of its confidence in the health of the economy. The FOMC expects that economic conditions will continue to evolve in a manner that will warrant additional gradual increases in the federal funds rate in 2018 and beyond. In addition to the FOMC increasing the target federal funds rate, the FRB also began to remove accommodation in 2017 by reducing the amount of debt held on its balance sheet. The FRB is expected to continue to wind-down its asset purchase program throughout 2018 and over the next several years. As the FOMC increases the federal funds rate and the FRB reduces its debt, it is possible that overall interest rates could rise, which may negatively impact the housing markets and the U.S. economy as a whole. In addition, deflationary pressures, while possibly lowering our operating costs, could have a significant negative effect on our borrowers, especially our business borrowers, and the values of collateral securing loans, which could negatively affect our financial performance.

The Company’s commercial loan portfolio is also impacted by fluctuations in the level of one-month LIBOR, as a large portion of this portfolio reprices based on this index, and to a lesser extent Prime. Our net interest income may be reduced if more interest-bearing liabilities than interest-earning assets reprice or mature during a period when interest rates are rising, or if more interest-earning assets than interest-bearing liabilities reprice or mature during a period when interest rates are declining.

The table below presents the Company’s anticipated repricing of loans and investment securities over the next four quarters.

	$	11,310,101	$	1,087,405	$	1,051,180	$	991,990	$	14,440,676

⁽¹⁾ Amounts include expected maturities, scheduled paydowns, expected prepayments, and loans subject to caps and floors, and exclude the repricing of assets from prior periods, as well as non-accrual loans and market value adjustments.

As part of its asset/liability management strategy, the Company has seen greater levels of loan originations with adjustable or variable rates of interest in commercial and consumer loan products, which typically have shorter terms than residential mortgage loans. The majority of fixed-rate, long-term, agency-conforming residential loans are sold in the secondary market to avoid bearing the interest rate risk associated with longer duration assets in the current rate environment. However, the Sabadell and Gibraltar acquisitions brought a considerable amount of jumbo, non-agency-conforming residential mortgage loan exposure onto the balance sheet, both fixed rate and variable rate in nature, which has increased the overall duration of the portfolio. Considering all of this, as of September 30, 2018, $13.5 billion, or 60%, of the Company’s total loan portfolio had variable interest rates, of which $2.3 billion, or 10%, had an expected repricing date beyond the next four quarters. The Company had no significant concentration to any single borrower or industry segment at September 30, 2018.

The Company’s strategy with respect to liabilities in recent periods has been to emphasize transaction accounts, particularly non-interest or low interest-bearing transaction accounts, which are significantly less sensitive to changes in interest rates. At September 30, 2018, 86% of the Company’s deposits were in transaction and limited-transaction accounts, compared to 89% at December 31, 2017. Non-interest-bearing transaction accounts were 28% of total deposits September 30, 2018 compared to 29% at December 31, 2017.

Much of the liquidity increase experienced in the past several years has been due to a significant increase in non-interest-bearing demand deposits. The behavior of non-interest-bearing deposits and other types of demand deposits is one of the most important assumptions used in determining the interest rate and liquidity risk positions. A loss of these deposits in the future would reduce the asset sensitivity of the Company’s balance sheet as interest-bearing funds would most likely be increased to offset the loss of this favorable funding source.

⁽¹⁾ Amounts exclude the repricing of liabilities from prior periods.

As part of an overall interest rate risk management strategy, derivative instruments may also be used as an efficient way to modify the repricing or maturity characteristics of on-balance sheet assets and liabilities. Management may from time to time engage in such derivative instruments to effectively manage interest rate risk. These derivative instruments of the Company would modify net interest sensitivity to levels deemed appropriate.

IMPACT OF INFLATION OR DEFLATION AND CHANGING PRICES

The unaudited consolidated financial statements and related financial data presented herein have been prepared in accordance with GAAP, which generally require the measurement of financial position and operating results in terms of historical dollars, without considering changes in relative purchasing power over time due to inflation. Unlike most industrial companies, the majority of the Company’s assets and liabilities are monetary in nature. As a result, interest rates generally have a more significant impact on the Company’s performance than does the effect of inflation. Although fluctuations in interest rates are neither completely predictable nor controllable, the Company regularly monitors its interest rate position and oversees its financial risk management by establishing policies and operating limits. Interest rates do not necessarily move in the same direction or in the same magnitude as the prices of goods and services, since such prices are affected by inflation to a larger extent than interest rates. Although not as critical to the banking industry as to other industries, inflationary factors may have some impact on the Company’s growth, earnings, total assets and capital levels.

Conversely, a period of deflation could affect our business, as well as all financial institutions and other industries. Deflation could lead to lower profits, higher unemployment, lower production and deterioration in overall economic conditions. In addition, deflation could depress economic activity, including loan demand and the ability of borrowers to repay loans, and consequently impair earnings through increasing the value of debt while decreasing the value of collateral for loans.

Management believes the most significant potential impact of inflation and deflation on financial results relates to the Company's ability to maintain a sufficient amount of capital to cushion against future losses. However, the Company could employ certain risk management tools to maintain its balance sheet strength in the event a deflationary scenario were to develop.

85

Non-GAAP Measures

This discussion and analysis included herein contains financial information determined by methods other than in accordance with GAAP. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance. Non-GAAP measures include, but are not limited to, descriptions such as core, tangible, and pre-tax pre-provision. These measures typically adjust GAAP performance measures to exclude the effects of the amortization of intangibles and include the tax benefit associated with revenue items that are tax-exempt, as well as adjust income available to common shareholders for certain significant activities or transactions that, in management’s opinion, can distort period-to-period comparisons of the Company’s performance. Transactions that are typically excluded from non-GAAP performance measures include realized and unrealized gains/losses on former bank owned real estate, realized gains/losses on securities, income tax gains/losses, merger related charges and recoveries, litigation charges and recoveries, and debt repayment penalties. Management believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of the Company’s core businesses. These non-GAAP disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Reconciliations of GAAP to non-GAAP disclosures are presented in Table 17, with the exception of forward-looking information. The Company is unable to estimate GAAP EPS guidance without unreasonable efforts due to the nature of one-time or unusual items that cannot be predicted, and therefore has not provided this information under Regulation S-K Item 10(e)(1)(i)(B).

⁽¹⁾ Fully taxable-equivalent (TE) calculations include the tax benefit associated with related income sources that are tax-exempt using a rate of 21% for 2018 and a rate of 35% for 2017.

⁽²⁾ Tangible calculations eliminate the effect of goodwill and acquisition-related intangibles and the corresponding amortization expense on a tax-effected basis where applicable.

⁽³⁾ Certain prior period amounts have been reclassified to conform to the net presentation requirements of ASU No. 2014-09, Revenue from Contracts with Customers, which was adopted effective January 1, 2018. On average, the adoption resulted in a reduction of non-interest income and non-interest expense of approximately $2.3 million on a quarterly basis, and had no impact on net income.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Quantitative and qualitative disclosures about market risk are presented at December 31, 2017 in Part II, Item 7A of the 2017 10-K, filed with the Securities and Exchange Commission on February 23, 2018. Additional information at September 30, 2018 is included herein under Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

Item 4. Controls and Procedures

An evaluation of the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2018 was carried out under the supervision, and with the participation of, the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”). Based on that evaluation, the CEO and CFO have concluded that the Company’s disclosure controls and procedures are effective in alerting them in a timely manner to material information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 (the “Exchange Act”).

Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed by the Company under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to the Company’s management, including the CEO and the CFO, as appropriate, to allow timely decisions regarding required disclosures. Disclosure controls include review of internal controls that are designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use and transactions are properly recorded and reported. There was no significant change in the Company’s internal controls over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the internal control over financial reporting.

Any control system, no matter how well conceived and operated, can provide only reasonable assurance that its objectives are achieved. The design of a control system inherently has limitations, including the controls’ cost relative to their benefits. Additionally, controls can be circumvented. No cost-effective control system can provide absolute assurance that all control issues and instances of fraud, if any, will be detected.

Part II. Other Information

Item 1. Legal Proceedings

See the "Legal Proceedings" section of "Note 16 – Commitments and Contingencies" of the Notes to the Unaudited Consolidated Financial Statements, incorporated herein by reference.

Item 1A. Risk Factors

For information regarding risk factors that could affect the Company's results of operations, financial condition and liquidity, see the risk factors disclosed in the "Risk Factors" section of the Company's 2017 10-K, filed with the Securities and Exchange Commission on February 23, 2018.

The risk factors below relate to the acquisition of Gibraltar Private Bank & Trust Co., which we refer to as "Gibraltar," and are in addition to the risk factors previously disclosed in the Company's 2017 10-K. The Company completed its acquisition of Gibraltar on March 23, 2018.

We may fail to realize all of the anticipated benefits of the Gibraltar acquisition.

The success of the acquisition will depend, in part, on our ability to realize the anticipated benefits and cost savings from combining our business with the business of Gibraltar. If we are not able to achieve these objectives, the anticipated benefits and cost savings of the Gibraltar acquisition may not be realized fully, or at all, or may take longer to realize than expected.

We have incurred significant transaction and acquisition-related integration costs in connection with the Gibraltar acquisition.

We have incurred significant costs associated with completing the Gibraltar acquisition and integrating Gibraltar’s operations, and are continuing to assess the impact of these costs. Although we believe that the elimination of duplicate costs, as well as the realization of other efficiencies related to the integration of Gibraltar’s business, will offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

(1) Includes shares of the Company's common stock acquired by the Company in connection with satisfaction of tax withholding obligations on vested restricted stock.

On May 10, 2018, IBERIABANK Corporation's Board of Directors authorized the repurchase of up to 1,137,500 shares of the Company's outstanding common stock. On November 5, 2018, the Company announced the completion of this program under which all of the authorized shares were purchased at a weighted average price of $77.54 per share. Also on November 5, 2018, the Company announced that the Board of Directors had authorized a new repurchase program of up to 2,765,000 shares of the Company's outstanding common stock, which equates to approximately 5% of the total shares outstanding. Stock repurchases under this new program will be made from time to time, on the open market or in privately negotiated transactions, at the discretion of the management of the Company and in accordance with the limitations set forth in Rule 10b-18 of the Securities and Exchange Commission, approval by all applicable regulatory agencies, and other applicable legal requirements. The timing of these repurchases will depend on market conditions and other requirements. The Company currently anticipates the share repurchase program will extend over a two-year time frame, or earlier if the shares have been repurchased. The share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and the program may be extended, modified, suspended, or discontinued at any time. For additional information regarding completion and commencement of the stock repurchase programs, see the Company's Current Report on Form 8-K filed on November 5, 2018, which is incorporated herein by reference.

Restrictions on Dividends and Repurchase of Stock

Holders of IBERIABANK Corporation common stock are only entitled to receive such dividends as the Company's Board of Directors may declare out of funds legally available for such payments. Furthermore, holders of IBERIABANK Corporation common stock are subject to the prior dividend rights of any holders of the Company's preferred stock then outstanding. There were 13,750 shares of preferred stock outstanding at September 30, 2018.

IBERIABANK Corporation understands the importance of returning capital to shareholders. Management will continue to execute the capital planning process, including evaluation of the amount of the common stock dividend, with the Board of Directors and in conjunction with the regulators, subject to the Company's results of operations. Also, IBERIABANK Corporation is a bank holding company, and its ability to declare and pay dividends is dependent on certain federal regulatory considerations, including the guidelines of the Federal Reserve regarding capital adequacy and dividends.
