Hancock Whitney reports third quarter 2024 EPS of $1.33

GULFPORT, Miss. (October 15, 2024) — Hancock Whitney Corporation (Nasdaq: HWC) today announced its financial results for the third quarter of 2024. Net income for the third quarter of 2024 totaled $115.6 million, or $1.33 per diluted common share (EPS), compared to $114.6 million, or $1.31 per diluted common share, in the second quarter of 2024. The company reported net income for the third quarter of 2023 of $97.7 million, or $1.12 per diluted common share.

Third Quarter 2024 Highlights

“The third quarter results reflect the continued strength and stability of our company,” said John M. Hairston, President & CEO. “Our efforts to improve profitability continued with another quarter of 1.32% ROA, additional NIM expansion, fee income growth, and lower operating expenses. Credit metrics continued to normalize with an increase in criticized commercial loans at the end of the quarter. Non-accrual loans were down, and we’ve maintained a solid ACL to loans of 1.46%. Our capital ratios continue to grow due to strong earnings and are at top quartile levels. As we reflect on and celebrate our 125th anniversary, we remain dedicated to demonstrating our strength, stability, and commitment to our shareholders, clients, communities, and associates.”

Loans

Total loans were $23.5 billion at September 30, 2024, down $456.0 million, or 2%, from June 30, 2024. The decrease was primarily due to the runoff of a Shared National Credit portfolio of $254 million as we remain focused on originating more granular loans, and higher payoffs on income-producing commercial real estate loans.

Average loans totaled $23.6 billion for the third quarter of 2024, down $365.4 million, or 2%, linked-quarter. Management expects 2024 period-end loan balances to be flat to down slightly from year-end 2023.

Deposits

Total deposits at September 30, 2024 were $29.0 billion, down $217.8 million, or less than 1%, from June 30, 2024. The linked-quarter decrease in deposits was driven primarily by a decrease in interest-bearing public funds driven by seasonal runoff and a decrease in DDAs. These decreases were partially offset by an increase in interest-bearing transactions and savings deposits due to mid-quarter inflows from equity markets and an increase in retail time deposits despite maturity concentrations and promotional rate reductions during the period.

DDAs totaled $10.5 billion at September 30, 2024, down $142.7 million, or 1%, from June 30, 2024 and comprised 36% of total period-end deposits. Interest-bearing transaction and savings deposits totaled $10.9 billion at the end of the third quarter of 2024, up $81.9 million, or 1%, linked-quarter. Compared to June 30, 2024, retail time deposits of $4.7 billion were up $70.3 million, or 2%, and brokered deposits were $190.5 million, down $9.6 million, or 5%, compared to the prior quarter. Interest-bearingpublic fund deposits decreased $217.6 million, or 7%, linked-quarter, totaling $2.7 billion at September 30, 2024.

Average deposits for the third quarter of 2024 were $28.9 billion, down $128.9 million, or less than 1%, linked-quarter. Management expects 2024 period-end deposit levels to be flat to down slightly from year-end 2023.

Asset Quality

The total allowance for credit losses (ACL) was $342.8 million at September 30, 2024, up $0.5 million, or less than 1%, from June 30, 2024. During the third quarter of 2024, the company recorded a provision for credit losses of $18.6 million, compared to a provision for credit losses of $8.7 million in the second quarter of 2024. There were $18.0 million of net charge-offs in the third quarter of 2024, or 0.30% of average total loans on an annualized basis, compared to net charge-offs of $7.3 million, or 0.12% of average total loans in the second quarter of 2024. The ratio of ACL to period-end loans was 1.46% at September 30, 2024, compared to 1.43% at June 30, 2024.

Criticized commercial loans totaled $508.0 million, or 2.81% of total commercial loans, at September 30, 2024, compared to $379.8 million, or 2.05% of total commercial loans at June 30, 2024. Nonaccrual loans totaled $82.9 million, or 0.35% of total loans, at September 30, 2024, compared to $86.3 million, or 0.36% of total loans, at June 30, 2024. ORE and foreclosed assets were $27.7 million at September 30, 2024, up $25.6 million, compared to June 30, 2024, largely due to property from one commercial borrower.

Net Interest Income and Net Interest Margin (NIM)

Net interest income (TE) for the third quarter of 2024 was $274.5 million, an increase of $1.2 million, or less than 1%, from the second quarter of 2024. The net interest margin (NIM) (TE) was 3.39% in the third quarter of 2024, up 2 bps linked-quarter. Higher rates on loans (+2 bps), higher securities yields (+1 bp) and a favorable borrowing mix (+1 bp), led to a 4 basis point improvement in NIM, partially offset by the change in deposit rates (-2 bps).

Average earning assets were $32.3 billion for the third quarter of 2024, down $275.6 million, or less than 1%, from the second quarter of 2024.

Non-GAAP Financial Measures

This news release includes non-GAAP financial measures to describe Hancock Whitney’s performance. These non-GAAP financial measures should not be considered alternatives to GAAP-basis financial statements and other bank holding companies may define or calculate these non-GAAP measures or similar measures differently. The reconciliations of those measures to GAAP measures are provided either in the financial tables or in Appendix A thereto.

Consistent with the provisions of subpart 229.1400 of the Securities and Exchange Commission’s Regulation S-K, “Disclosures by Bank and Savings and Loan Registrants,” the company presents net interest income, net interest margin and efficiency ratios on a fully taxable equivalent (“TE”) basis. The TE basis adjusts for the tax-favored status of net interest income from certain loans and investments using the statutory federal tax rate to increase tax-exempt interest income to a taxable equivalent basis. The company believes this measure to be the preferred industry measurement of net interest income and it enhances comparability of net interest income arising from taxable and tax-exempt sources.

The company presents certain additional non-GAAP financial measures to assist the reader with a better understanding of the company’s performance period over period, as well as to provide investors with assistance in understanding the success management has experienced in executing its strategic initiatives. The company highlights certain items that are outside of our principal business and/or are not indicative of forward-looking trends in supplemental disclosures items below our GAAP financial data and presents certain “Adjusted” ratios that exclude these disclosed items. These adjusted ratios provide management or the reader with a measure that may be more indicative of forward-looking trends in our business, as well as demonstrates the effects of significant gains or losses and changes.

We define Adjusted Pre-Provision Net Revenue as net income excluding provision expense and income tax expense, plus the taxable equivalent adjustment (as defined above), less supplemental disclosure items (as defined above). Management believes that adjusted pre-provision net revenue is a useful financial measure because it enables investors and others to assess the company’s ability to generate capital to cover credit losses through a credit cycle. We define Adjusted Revenue as net interest income (te) and noninterest income less supplemental disclosure items. We define Adjusted Noninterest Expense as noninterest expense less supplemental disclosure items. We define our Efficiency Ratio as noninterest expense to total net interest income (te) and noninterest income, excluding amortization of purchased intangibles and supplemental disclosure items, if applicable. Management believes adjusted revenue, adjusted noninterest expense and the efficiency ratio are useful measures as they provide a greater understanding of ongoing operations and enhance comparability with prior periods.
