NET INTEREST INCOME

Net interest income decreased $2.0 million to $81.6 million during the first quarter of 2024 from $83.6 million for the quarter ended December 31, 2023. The net interest margin decreased 9 basis points to 3.06 percent for the three months ended March 31, 2024 from 3.15 percent for the three months ended December 31, 2023, primarily driven by higher funding costs.

NON-INTEREST INCOME

Total non-interest income for the quarter ended March 31, 2024 decreased $1.7 million to $6.3 million from $8.0 million for the quarter ended December 31, 2023. The decrease was primarily driven by a decline of $1.1 million in other non-interest income which was primarily driven by the mark to market on interest rate swaps on participated loans of $0.8 million, a $0.4 million decline in gain on sales of loans and leases, and a $0.3 million decline in loan derivative income, net, partially offset by an increase of $0.3 million in loan fees.

PROVISION FOR CREDIT LOSSES

The Company recorded a provision for credit losses of $7.4 million for the quarter ended March 31, 2024, compared to $3.8 million for the quarter ended December 31, 2023. The increase in provision was largely driven by an increase in expected losses in the Company's equipment finance businesses.

Total net charge-offs for the first quarter of 2024 were $8.8 million compared to $7.1 million in the fourth quarter of 2023. The $8.8 million in net charge-offs were largely driven by $4.7 million in commercial loans, the majority of which was previously specifically reserved for, and $3.5 million in equipment financing. The equipment financing charge-offs were largely small dollar specialty vehicle charge-offs. The ratio of net loan and lease charge-offs to average loans and leases on an annualized basis increased to 36 basis points for the first quarter of 2024 from 30 basis points for the fourth quarter of 2023.

The allowance for loan and lease losses represented 1.24 percent of total loans and leases at March 31, 2024, compared to 1.22 percent at December 31, 2023, and 1.31 percent at March 31, 2023.

ASSET QUALITY

The ratio of nonperforming loans and leases to total loans and leases was 0.42 percent at March 31, 2024, a decrease from 0.45 percent at December 31, 2023. Total nonaccrual loans and leases decreased $3.0 million to $40.7 million at March 31, 2024 from $43.6 million at December 31, 2023. The ratio of nonperforming assets to total assets was 0.37 percent at March 31, 2024, a decrease from 0.40 percent at December 31, 2023. Total nonperforming assets decreased $2.8 million to $42.5 million at March 31, 2024 from $45.3 million at December 31, 2023.

NON-INTEREST EXPENSE

Non-interest expense for the quarter ended March 31, 2024 increased $1.8 million to $61.0 million from $59.2 million for the quarter ended December 31, 2023. The increase was primarily driven by increases of $1.2 million in compensation and employee benefits expense, $0.8 million in advertising and marketing expense, $0.6 million in occupancy expense, and $0.5 million in professional services expense, partially offset by decreases of $0.9 million in other non-interest expense, $0.3 million in amortization of identified intangible assets expense, and $0.2 million in equipment and data processing expense.

PROVISION FOR INCOME TAXES

The effective tax rate was 24.7 percent for the three months ended March 31, 2024 compared to 19.9 percent for the three months ended December 31, 2023 and 12.8 percent for the three months ended March 31, 2023.

We may also make forward-looking statements in other documents we file with the Securities and Exchange Commission ("SEC"), in our annual reports to shareholders, in press releases and other written materials, and in oral statements made by our officers, directors or employees. You can identify forward looking statements by the use of the words "believe," "expect," "anticipate," "intend," "estimate," "assume," "outlook," "will," "should," and other expressions that predict or indicate future events and trends and which do not relate to historical matters, including statements regarding the Company's business, credit quality, financial condition, liquidity and results of operations. Forward-looking statements may differ, possibly materially, from what is included in this press release due to factors and future developments that are uncertain and beyond the scope of the Company's control. These include, but are not limited to, changes in interest rates; general economic conditions (including inflation and concerns about liquidity) on a national basis or in the local markets in which the Company operates; turbulence in the capital and debt markets; competitive pressures from other financial institutions; changes in consumer behavior due to changing political, business and economic conditions, or legislative or regulatory initiatives; changes in the value of securities and other assets in the Company's investment portfolio; increases in loan and lease default and charge-off rates; the adequacy of allowances for loan and lease losses; decreases in deposit levels that necessitate increases in borrowing to fund loans and investments; operational risks including, but not limited to, cybersecurity incidents, fraud, natural disasters, and future pandemics; changes in regulation; the possibility that future credit losses may be higher than currently expected due to changes in economic assumptions and adverse economic developments; the risk that goodwill and intangibles recorded in the Company's financial statements will become impaired; and changes in assumptions used in making such forward-looking statements. Forward-looking statements involve risks and uncertainties which are difficult to predict. The Company's actual results could differ materially from those projected in the forward-looking statements as a result of, among others, the risks outlined in the Company's Annual Report on Form 10-K, as updated by its Quarterly Reports on Form 10-Q and other filings submitted to the SEC. The Company does not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made.
