IBERIABANK Corporation Reports Fourth Quarter Results; Achieves 2020 Financial Metrics For Full Year 2018

LAFAYETTE, LOUISIANA -- IBERIABANK Corporation (NASDAQ: IBKC), holding company of the 131-year-old IBERIABANK (www.iberiabank.com), reported financial results for the fourth quarter ended December 31, 2018. For the quarter, the Company reported net income available to common shareholders of $129.1 million, or $2.32 diluted earnings per common share (“EPS”). On a non-GAAP basis, EPS excluding non-core revenues and non-core expenses ("Core EPS") in the fourth quarter of 2018 was $1.86 per common share, compared to $1.33 in the year-ago period, an increase of 40% (refer to press release supplemental tables for a reconciliation of GAAP to non-GAAP metrics).

Daryl G. Byrd, President and Chief Executive Officer, commented, “Our focus on delivering sustainable, profitable growth culminated in another stellar quarter, allowing us to achieve our 2020 financial metrics for the third consecutive quarter, as well as the full year 2018.  Our strong balance sheet and outstanding performance for the year was achieved while improving our already excellent credit quality metrics and operating efficiency. Continued financial progress, combined with a high quality and diverse franchise throughout the Southeast, position us to increase value for our clients and shareholders in 2019 and beyond." 

Highlights for the fourth quarter of 2018 and at December 31, 2018:

Tangible Efficiency Ratio (TE)	N/A			N/A			50.7		%	51.9		%	N/A			N/A			53.7		%	57.6		%

• Strong improvement in both GAAP and Core EPS resulting from increases in both loans and deposits, margin expansion and focused expense management resulted in the Company achieving its 2020 financial metrics in both 4Q18 and for the full-year 2018.

• Revenue growth and continued expense reduction produced positive operating leverage in the quarter and resulted in a Core Tangible Efficiency Ratio of 50.7%.

1

• Credit metrics are strong and continue to improve. Criticized, classified, and non-performing assets were down 28%, 30%, and 5%, respectively, from the same time a year ago. The allowance for loan and lease losses (ALLL) to total loans and leases remained flat and covered 101% of non-performing loans.  

• The Company's reported and cash net interest margins improved 7 and 5 basis points on a linked quarter basis, to 3.81% and 3.52%, respectively.

• Non-interest expense was relatively unchanged from the prior quarter. Core non-interest expense declined $2.0 million, or 5% on an annualized basis, from the prior quarter.

• Total loan growth of $175.9 million, or 3% annualized. Loan growth continues to be impacted by accelerated payoffs.

• Total deposits increased $570.0 million, or 10% annualized. As of December 31, 2018, total non-interest bearing deposits represented 28% of total deposits.

• On November 5, 2018, the Company announced a new repurchase plan, its 11^th plan, of up to 2,765,000 shares of the Company's outstanding common stock.  The newly authorized plan equates to approximately 5% of the total common shares outstanding.

• During 4Q18, the Company repurchased 1.21 million common shares, or 2.1% of the shares outstanding, at a weighted average price of $72.61 per common share. Of the shares repurchased, 709,290 shares were purchased under the 10th plan and 500,000 under the 11th plan.

• On October 19, 2018, the Company announced a fourth quarter cash dividend equal to $0.41 per common share, payable on January 25, 2019. This equated to a 5% increase to the third quarter dividend, and was the third common dividend increase of 2018.

4Q18 Special Items

• In connection with filing its 2017 income tax returns, the Company recorded a non-core, permanent net income tax benefit of approximately $65.3 million in the fourth quarter of 2018. This benefit was a result of deductions claimed on the 2017 income tax returns associated with unrealized losses on securities and loans and depreciation on real and personal property.

• During 4Q18, the Company restructured portions of its investment portfolio selling approximately $1 billion of securities at a pre-tax loss of approximately $49.8 million ($37.9 million after-tax) and subsequently purchased $1 billion in securities during the quarter. The incremental yield on the purchased securities was 164 basis points.

Operating Results

Net interest income increased$5.8 million, or 2%, on a linked quarter basis. Average loans increased$201.8 million, or 4% annualized, and the associated taxable-equivalent yield increased17 basis points. The yield on total earning assets was 17 basis points higher at 4.74% compared to 4.57% in the linked quarter.

4

Average interest-bearing deposits increased $281.3 million, or 7% annualized, and the average cost of interest-bearing deposits rose 17 basis points to 123 basis points on a linked quarter basis. Total average interest-bearing liabilities increased by $121.5 million, or 3% annualized, and the average cost of interest-bearing liabilities rose 14 basis points to 134 basis points. The total cost of interest-bearing liabilities rose primarily due to an upward repricing of deposits, promotional activity in customer time deposits, and brokered wholesale CD issuances. The total cost of funding in the fourth quarter of 2018 was 100 basis points, compared to 89 basis points in the linked quarter.

The increase in average earning assets and higher loan yields, offset by the increase in average interest-bearing liabilities and cost of funds, resulted in improvements in the Company's reported and cash net interest margins of 7 and 5 basis points to 3.81% and 3.52%, respectively.    

Credit metrics are strong and continue to improve. Criticized, classified, and non-performing assets were down 28%, 30%, and 5%, respectively, from the same time a year ago. The ALLL to total loans and leases remained flat and covered 101% of non-performing loans.  

Non-interest income decreased $52.1 million compared to the linked quarter, primarily driven by $49.8 million in losses on sales of available-for-sale securities. Non-interest income on a linked quarter basis also included a $2.4 million decline in mortgage income and a $0.7 million decline in broker commissions. These decreases were partially offset by increases of $0.4 million in commercial loan fee income and $0.3 million in income from new market tax credit investments.

Non-interest expense remained relatively flat when compared to the linked quarter. Professional services expenses increased $3.1 million and were offset by decreases in insurance and net costs of OREO of $1.9 million and $1.8 million, respectively. During the fourth quarter of 2018, non-interest expense included $2.6 million in non-core expenses, primarily from tax-related professional services expenses.

Excluding these items, core non-interest expense decreased $2.0 million, or 1%, primarily driven by decreases of $2.8 million in net costs of OREO and $1.9 million in insurance expenses, partially offset by increases of $1.5 million in salary and employee benefits expenses and $0.6 million in marketing expenses.

Income tax expense decreased $76.5 million on a linked quarter basis to an income tax benefit position of $46.1 million as the result of a $65.3 million non-core, permanent net tax benefit recorded in the fourth quarter of 2018. This benefit was a result of deductions claimed on the Company's 2017 income tax returns partially offset by the repricing of its current and deferred income tax position associated with the Tax Cuts and Jobs Act of 2017.

On a linked quarter basis, the efficiency ratio increased to 63.5% from 54.1%, primarily due to losses on sales of available-for-sale securities in the fourth quarter, while the non-GAAP core tangible efficiency ratio improved to 50.7% from 51.9%. The Company continues to focus on cost containment and revenue enhancement efforts to deliver positive operating leverage. Refer to Table A for a summary of financial results on both a GAAP and non-GAAP basis.

Loans and Other Assets

Total loans increased $175.9 million, or 3% annualized, to $22.5 billion at December 31, 2018. Period-end loan growth during the fourth quarter of 2018 was strongest in the Energy Group (primarily reserve-based lending), the Corporate Asset Finance Group (equipment financing business), and the New Orleans, Baton Rouge and Birmingham markets. The Company believes it is well-positioned for diversified loan growth based on our strategic presence in significant MSAs in the Southeastern United States.

On an average balance and linked quarter basis, the investment portfolio decreased $111.0 million, or 9% annualized, to $4.8 billion, mainly due to sales of available-for-sale securities. On a period-end and linked quarter basis, the investment portfolio increased $143.3 million, or 12% annualized, to $5.0 billion, mainly due to favorable market value adjustments coupled with purchases of available-for-sale securities late in the fourth quarter. Approximately 96% of the Company's investment portfolio is in available-for-sale securities, which experience unrealized losses as interest rates rise. The investment portfolio had an effective duration of 3.4 years at December 31, 2018, down from 4.0 years at September 30, 2018, and a $62.9 million unrealized loss at December 31, 2018, down from a $181.1 million loss at September 30, 2018. The average yield on investment securities increased 18 basis points to 2.61% in the fourth quarter of 2018. The Company holds in its investment portfolio primarily government agency securities. Municipal securities comprised 7% of total investments at December 31, 2018.

Non-GAAP Financial Measures

This press release 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 in this press release 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, debt repayment penalties, and gains, losses, and impairment charges on long-lived assets. 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 the supplemental tables at the end of this release. Please refer to the supplemental tables for these reconciliations.

Safe Harbor And Non-GAAP Financial Measures Safe Harbor To the extent that statements in this PowerPoint presentation relate to future plans, objectives, financial results or performance of IBERIABANK Corporation, these statements are deemed to be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements, which are based on management’s current information, estimates and assumptions and the current economic environment, are generally identified by the use of the words “plan”, “believe”, “expect”, “intend”, “anticipate”, “estimate”, “project” or similar expressions. The Company’s actual strategies, results and financial condition in future periods may differ materially from those currently expected due to various risks and uncertainties. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements. Consequently, no forward-looking statement can be guaranteed. Except to the extent required by applicable law or regulation, the Company undertakes no obligation to revise or update publicly any forward-looking statement for any reason. This PowerPoint presentation supplements information contained in the Company’s earnings release dated January 25, 2019, and should be read in conjunction therewith. The earnings release may be accessed on the Company’s web site, www.iberiabank.com, under “Investor Relations” and then “Financial Information” and then “Press Releases.” Non-GAAP Financial Measures This PowerPoint presentation contains financial information determined by methods other than in accordance with GAAP. The Company’s management uses core non-GAAP financial metrics (“Core”) in their analysis of the Company’s performance to identify core revenues and expenses in a period that directly drive operating net income in that period. These Core measures typically adjust GAAP performance measures to exclude the effects of the amortization of intangibles and include the tax benefits 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. Reference is made to “Non-GAAP Financial Measures” and “Caution About Forward Looking Statements” in the earnings release which also apply to certain disclosures in this PowerPoint presentation. 2

There were 2,265,000 remaining common shares that may be repurchased under the current Board authorized plan at December 31, 2018. • In connection with filing its 2017 income tax returns, the Company recorded a non-core, permanent net income tax benefit of approximately $65 million in the fourth quarter of 2018.
