THE FIRST OF LONG ISLAND CORPORATION

REPORTS EARNINGS FOR THE FIRST QUARTER OF 2025

Melville, New York, April 30, 2025 (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 months ended March 31, 2025.

Analysis of Earnings – First Quarter 2025 Versus Linked Quarter

Net income for the first quarter of 2025 increased $512,000 compared to the fourth quarter of 2024. The increase in net income was primarily due to a $795,000 increase in net interest income largely due to an eight basis point improvement in the net interest margin, and a decrease in noninterest expense of $1.5 million primarily due to branch consolidation expenses of $1.4 million and vesting of equity awards during the fourth quarter of 2024 offset by pending merger related system conversion expenses of $468,000 and debit card chargeoffs of $243,000 during the first quarter of 2025. These were partially offset by a provision for credit losses of $168,000 as compared to a provision reversal for credit losses of $381,000 in the fourth quarter, a decrease in noninterest income of $503,000 primarily due to $233,000 of back-to-back swap fees and $225,000 of bank-owned life insurance ("BOLI") benefit payments earned in the fourth quarter, and an increase in income tax expense of $761,000 substantially due to a decrease in the percentage of pre-tax income derived from the Bank's real estate investment trust, increasing the state and local income tax due.

Analysis of Earnings - First Quarter 2025 Versus First Quarter of 2024

Net income and earnings per share ("EPS") for the quarter ended March 31, 2025 were $3.8 million and $0.17, respectively, as compared to $4.4 million and $0.20, respectively, for the comparable quarter in 2024. The principal drivers of the change in net income were an increase in net interest income of $661,000, or 3.6%, which was more than offset by an increase in the provision for credit losses of $168,000, an increase in noninterest expense of $922,000, and an increase in income tax expense of $193,000. The quarter produced a return on average assets ("ROA") of 0.37%, return on average equity ("ROE") of 3.98%, and a net interest margin of 1.91%.

Net interest income increased when comparing the first quarters of 2025 and 2024 primarily due to a decrease in interest expense of $2.0 million which was partially offset by a $1.4 million decrease in interest income. The decrease in interest expense was a combination of a 16 basis points decrease in the cost of interest-bearing liabilities and a decrease in average interest-bearing liabilities of $92.9 million. The decrease in interest income resulted from interest-earning assets decreasing by $156.6 million offset by the yield on interest-earning assets increasing two basis points.

In the first quarter of 2025, the Bank recorded a provision for credit losses of $168,000. The Bank did not record a provision in the first quarter of 2024. The allowance for credit losses remained relatively flat when compared to year-end 2024 largely due to declines in historical loss rates and loan balances which were offset by an increase due to deterioration in current and forecasted economic conditions, including adjustments for economic uncertainty. The reserve coverage ratio ticked up one basis point to 0.89% of total loans at March 31, 2025 as compared to 0.88% at December 31, 2024. Past due loans and nonaccrual loans were at $7.5 million and $3.5 million, respectively, on March 31, 2025. Overall, the credit quality of the loan and investment portfolios remains strong.

Noninterest income decreased $57,000, or 2.1%, when comparing the first quarters of 2025 and 2024 mainly due to 2024 nonrecurring items of $114,000 in real estate tax refunds, $60,000 in BOLI benefit payments, $50,000 in joint marketing fees and an additional one-time service charge cycle related to the Bank's core system conversion, which were partially offset by increases of $96,000 in merchant card service fees and $72,000 in BOLI accretion.

Noninterest expense increased $922,000, or 5.7%, for the first quarter of 2025, as compared to the first quarter of 2024. The change in noninterest expense is mainly attributable to the current year's expenses related to the pending merger. Noninterest expense increased due to merger expenses of $230,000, merger related system conversion expenses of $468,000, debit card chargeoffs of $243,000 and higher legal fees, partially offset by a 2.6% year-over-year decrease in salaries and employee benefits. The decrease in salaries and employee benefits was due to a decrease in full time equivalent employees, primarily the result of branch closings in 2024.

Income tax expense increased $193,000 due to an increase in the effective tax rate from 6.2% in the first quarter of 2024 to 11.5% in the current quarter. The increase in the effective tax rate is mainly due to the same reasons discussed above with respect to the linked quarter changes.

Liquidity

Total average deposits declined by $51.9 million when comparing the first quarters of 2025 and 2024. There were no overnight advances on March 31, 2025 or December 31, 2024. On March 31, 2025, other borrowings were down by $75.0 million from year-end 2024. At March 31, 2025, the Bank had $653.3 million in collateralized borrowing lines with the Federal Home Loan Bank of New York and the Federal Reserve Bank, a $20.0 million unsecured line of credit with a correspondent bank and $204.8 million in unencumbered securities. In total, $878.1 million in liquidity was available on March 31, 2025. Uninsured deposits were 49.5% of total deposits at March 31, 2025.

Capital

The Corporation’s capital position remains strong with a leverage ratio of approximately 10.29% on March 31, 2025. Book value per share was $16.91 on March 31, 2025, versus $16.77 on December 31, 2024. The Company declared its quarterly cash dividend of $0.21 per share during the quarter. There were no share repurchases during the quarter.
