THE FIRST OF LONG ISLAND CORPORATION

REPORTS EARNINGS FOR THE THIRD QUARTER OF 2024

Melville, New York, October 24, 2024 (GLOBE NEWSWIRE) – The First of Long Island Corporation (Nasdaq: FLIC, the “Company” or the “Corporation”), the parent of The First National Bank of Long Island (the “Bank”), reported earnings for the three and nine months ended September 30, 2024.

President and Chief Executive Officer Chris Becker commented on the Company's results: "We are encouraged by a second consecutive linked quarter showing improvements in key financial metrics. After an increase in the net interest margin of one basis point in the second quarter of 2024 from the first quarter of 2024, the margin increased nine basis points in the third quarter of 2024 when compared to second quarter of 2024. We are optimistic the trend will continue during the fourth quarter of this year. Excluding merger and branch consolidation expenses, our noninterest expense remains well controlled and in line with expectations. Finally, our credit quality results remained strong."

Analysis of Earnings - Nine Months Ended September 30, 2024

Net income and earnings per share ("EPS") for the nine months ended September 30, 2024, were $13.8 million and $0.61, respectively, as compared to $20.2 million and $0.89, respectively, in the same period of 2023. Adjusted net income and EPS for the current nine-month period, which exclude merger and branch consolidation expenses, were $14.8 million and $0.66, respectively (see "Non-GAAP Reconciliation" table at the end of this release). The principal drivers of the change in adjusted net income were a decline in net interest income of $11.7 million, or 17.5%, and a provision for credit losses of $740,000 as compared to a provision reversal of $1.2 million in the prior period, partially offset by a loss on sales of securities of $3.5 million in the first quarter of 2023, an increase in remaining noninterest income of $1.4 million, and decreases in noninterest expense of $1.2 million and income tax expense of $2.2 million. The nine months ended 2024 produced a return on average assets ("ROA") of 0.44%, a return on average equity ("ROE") of 4.88%, an efficiency ratio of 76.39%, and a net interest margin of 1.83%. Excluding merger and branch consolidation expenses, adjusted ROA and ROE were 0.47% and 5.23%, respectively, and the adjusted efficiency ratio was 74.21% (see "Non-GAAP Reconciliation" table at the end of this release).

Net interest income declined when comparing the first nine months of 2024 and 2023 due to an increase in interest expense of $23.4 million that was only partially offset by a $11.7 million increase in interest income. The cost of interest-bearing liabilities increased 109 basis points while the yield on interest-earning assets increased 38 basis points when comparing the nine-month periods. The Bank's balance sheet remains liability sensitive, however the pace of repricing of average interest-earning assets began outpacing the repricing of average interest-bearing liabilities in the third quarter.

The Bank recorded a provision for credit losses of $740,000 for the nine months ended 2024, compared to a provision reversal of $1.2 million in the same period of 2023. The allowance for credit losses declined when compared to year-end 2023 largely due to declines in historical loss rates and reserves on individually evaluated loans, partially offset by a deterioration in current and forecasted economic conditions, including adjustments for rent stabilization status of multifamily properties. The reserve coverage ratio remained stable at 0.88% of total loans at September 30, 2024 as compared to 0.88% at June 30, 2024 and 0.89% at December 31, 2023. Past due loans and nonaccrual loans were at $346,000 and $2.9 million, respectively, on September 30, 2024. Overall credit quality of the loan and investment portfolios remains strong.

Noninterest income, excluding the loss on sales of securities of $3.5 million in the 2023 period, increased $1.4 million, or 19.1%, when comparing the first nine months of 2024 and 2023. Recurring components of noninterest income including bank-owned life insurance (“BOLI”) and service charges on deposit accounts had increases of 8.0% and 13.4%, respectively. Other noninterest income increased 33.2% and included increases of $469,000 in merchant card services, $232,000 in back-to-back swap fees, and $181,000 in pension income, which were partially offset by a gain on disposition of premises and fixed assets of $240,000 in 2023.

Noninterest expense increased $254,000, or 0.5%, for the nine months of 2024, as compared to the same period in 2023. Excluding merger and branch consolidation expenses, adjusted noninterest expense decreased by $1.2 million (See "Non-GAAP Reconciliation" table at the end of this release). Reductions in occupancy and equipment expense of $685,000 and telecommunication expense of $383,000 drove the decline in adjusted noninterest expense. The decrease in occupancy and equipment expense was largely due to the ongoing branch optimization strategy, which resulted in the closing of various locations. Telecom expense decreased mainly due to efficiencies associated with system upgrades.

Income tax expense decreased $2.7 million, and the effective tax rate declined to (0.3)% for the nine months ended 2024 as compared to 11.6% for the same period in prior year. The decline in the effective tax rate is mainly due to an increase in the percentage of pre-tax income derived from the Bank’s real estate investment trust reducing the state and local income tax due. The decrease in income tax expense reflects the lower effective tax rate and a decline in pre-tax income.

Analysis of Earnings – Third Quarter 2024 Versus Third Quarter 2023

Net income for the third quarter of 2024 decreased $2.2 million as compared to the third quarter of last year. Adjusted net income for the third quarter decreased by $1.2 million (see "Non-GAAP Reconciliation" table at the end of this release). The change in adjusted net income is mainly attributable to a $2.8 million decline in net interest income for substantially the same reasons discussed above with respect to the nine-month periods along with a $341,000 increase in the provision for credit losses. Partially offsetting the decreases, was an increase in noninterest income of $966,000 for substantially the same reasons discussed above with respect to the nine-month periods. The quarter produced a ROA of 0.44%, a ROE of 4.77%, an efficiency ratio of 79.09%, and a net interest margin of 1.89%. On an adjusted basis, ROA and ROE were 0.53% and 5.79%, respectively, and the efficiency ratio was 72.69% (see "Non-GAAP Reconciliation" table at the end of this release).

Analysis of Earnings –Third Quarter 2024 Versus Second Quarter 2024

Net income for the third quarter of 2024 decreased $199,000 compared to the second quarter of 2024. Adjusted net income for the third quarter increased by $782,000 (see "Non-GAAP Reconciliation" table at the end of this release). The increase in adjusted net income was partially due to an increase in net interest income of $169,000, a decrease in the provision for credit losses of $400,000, and an increase in back-to-back swap fees of $232,000.

Net interest income increased due to an increase in net interest margin. The increase in the net interest margin to 1.89% in the third quarter of 2024 from 1.80% in the second quarter of 2024 was largely due to the repricing of wholesale funding at lower costs largely offsetting the increase in cost of other interest-bearing liabilities while the yield on interest-earning assets continued to rise. Additionally, average interest-bearing deposits decreased $35.8 million and average higher cost borrowings decreased $65.6 million.

The decrease in income tax expense was substantially due to the same reasons discussed above with respect to the nine-month periods.

Liquidity

Total average deposits declined by $89.6 million, or 2.6%, when comparing the nine-month periods of 2024 and 2023. On September 30, 2024, overnight advances and other borrowings were down by $70.0 million and $27.5 million, respectively, from year-end 2023. The Bank had $582.8 million in collateralized borrowing lines with the Federal Home Loan Bank of New York and the Federal Reserve Bank, as well as a $20 million unsecured line of credit with a correspondent bank. We also had $312.9 million in unencumbered cash and securities. In total, we had approximately $915.7 million of available liquidity on September 30, 2024. At September 30, 2024, uninsured deposits were 45.9% of total deposits.

Capital

The Corporation’s capital position remains strong with a leverage ratio of approximately 10.13% on September 30, 2024. Book value per share was $17.25 on September 30, 2024, versus $16.83 on December 31, 2023. The accumulated other comprehensive loss component of stockholders’ equity is mainly comprised of a net unrealized loss in the available-for-sale securities portfolio due to higher market interest rates. The Company declared its quarterly cash dividend of $0.21 per share during the quarter. There were no share repurchases during the quarter. The Board and management continue to evaluate the quarterly dividend to provide the best opportunity to maximize shareholder value.

NON-GAAP RECONCILIATION

(Unaudited)

The following tables provide supplemental non-GAAP financial measures which management uses internally to help understand, manage, and evaluate our business performance and to help make operating decisions. These supplemental financial measures are not measurements of financial performance under generally accepted accounting principles in the United States ("GAAP") and, as a result may not be comparable to similarly titled measures of other companies. The Corporation believes that these non-GAAP financial measures are useful to investors and analysts in comparing our performance across reporting periods on a consistent basis. The Corporation also believes the use of these non-GAAP financial measures can facilitate comparison of our operating results to those of our competitors. The following non-GAAP financial measures exclude merger related and branch consolidation expenses:
