Total investment securities at December 31, 2023 increased $36.2 million to $916.6 million from $880.4 million at September 30, 2023, and increased $259.8 million from $656.8 million at December 31, 2022. Total cash and cash equivalents at December 31, 2023 decreased $28.0 million to $133.0 million from $161.0 million at September 30, 2023, and decreased $249.9 million from $383.0 million at December 31, 2022. As of December 31, 2023, total investment securities and total cash and cash equivalents represented 9.2 percent of total assets as compared to 9.3 percent and 11.3 percent as of September 30, 2023 and December 31, 2022, respectively.

Total deposits at December 31, 2023 decreased $17.9 million, $13.2 million of which was related to brokered deposits, to $8.5 billion from $8.6 billion at September 30, 2023 and increased $2.0 billion from $6.5 billion at December 31, 2022, primarily driven by the completion of the PCSB acquisition.

Total borrowed funds at December 31, 2023 increased $241.6 million to $1.4 billion from $1.1 billion at September 30, 2023, driven by the need to fund loan growth during the quarter, and decreased $56.0 million from $1.4 billion at December 31, 2022.

The ratio of stockholders' equity to total assets was 10.53 percent at December 31, 2023, as compared to 10.36 percent at September 30, 2023, and 10.80 percent at December 31, 2022. The ratio of tangible stockholders' equity to tangible assets (non-GAAP) was 8.39 percent at December 31, 2023, as compared to 8.16 percent at September 30, 2023, and 9.20 percent at December 31, 2022.

NET INTEREST INCOME

Net interest income decreased $0.5 million to $83.6 million during the fourth quarter of 2023 from $84.1 million for the quarter ended September 30, 2023. The net interest margin decreased 3 basis points to 3.15 percent for the three months ended December 31, 2023 from 3.18 percent for the three months ended September 30, 2023, primarily driven by higher funding costs.

NON-INTEREST INCOME

Total non-interest income for the quarter ended December 31, 2023 increased $2.5 million to $8.0 million from $5.5 million for the quarter ended September 30, 2023. The increase was primarily driven by an increase of $2.0 million in other non-interest income, due to the mark to market on interest rate swaps, an increase of $0.4 million in loan level derivative income, net, and an increase of $0.2 million in gain on sales of loans and leases.

PROVISION FOR CREDIT LOSSES

The Company recorded a provision for credit losses of $3.8 million for the quarter ended December 31, 2023, compared to $3.0 million for the quarter ended September 30, 2023. The provision was driven by net charge-offs, an increase in specific reserves and strong loan growth, partially offset by a reduction in the unfunded reserve.

Total net charge-offs for the fourth quarter of 2023 were $7.1 million compared to $11.0 million in the third quarter of 2023, of which $4.5 million was previously reserved for. The $7.1 million in net charge-offs were driven by three individual charge-offs including a $3.3 million commercial loan, $1.0 million equipment financing loan, and a $0.9 million commercial real estate loan. The ratio of net loan and lease charge-offs to average loans and leases on an annualized basis decreased to 30 basis points for the fourth quarter of 2023 from 47 basis points for the third quarter of 2023.

The allowance for loan and lease losses represented 1.22 percent of total loans and leases at December 31, 2023, compared to 1.27 percent at September 30, 2023, and 1.29 percent at December 31, 2022. The decrease in ratio is driven by a change in loan mix consisting of a reduction in total construction commitments.

ASSET QUALITY

The ratio of total nonperforming loans and leases to total loans and leases was 0.45 percent at December 31, 2023 as compared to 0.55 percent at September 30, 2023. Total nonaccrual loans and leases decreased $7.6 million to $43.6 million at December 31, 2023 from $51.2 million at September 30, 2023. The ratio of nonperforming assets to total assets was 0.40 percent at December 31, 2023 as compared to 0.46 percent at September 30, 2023. Total nonperforming assets decreased $6.2 million to $45.3 million at December 31, 2023 from $51.5 million at September 30, 2023.

NON-INTEREST EXPENSE

Non-interest expense for the quarter ended December 31, 2023 increased $1.6 million to $59.2 million from $57.7 million for the quarter ended September 30, 2023. The increase was primarily driven by increases of $1.9 million in compensation and employee benefits and $0.5 million in equipment and data processing, partially offset by decreases of $0.9 million in professional services expense, $0.4 million in advertising and marketing expense, and $0.3 million in FDIC insurance expense.

PROVISION FOR INCOME TAXES

The effective tax rate was 19.9 percent and 20.1 percent for the three and twelve months ended December 31, 2023 compared to 21.4 percent for the three months ended September 30, 2023 and 17.8 percent and 21.6 percent for the three and twelve months ended December 31, 2022.

RETURNS ON AVERAGE ASSETS AND AVERAGE EQUITY

The annualized return on average assets was 0.81 percent during the fourth quarter of 2023 and flat compared to the third quarter of 2023; and was 0.67 percent for the year ended December 31, 2023, compared to 1.27 percent for the year ended December 31, 2022.

The annualized return on average tangible stockholders' equity increased to 10.12 percent during the fourth quarter of 2023 compared to 10.09 percent for the third quarter of 2023; and was 8.36 percent for the year ended December 31, 2023 compared to 13.35 percent for the year ended December 31, 2022.

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.

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.
