Notes to Unaudited Consolidated Financial Statements
Note 1 – Consolidated Financial Statements
Basis of Presentation

The consolidated financial statements are comprised of the accounts of Northfield Bancorp, Inc. and its wholly owned subsidiaries, Northfield Investments, Inc. and Northfield Bank (the “Bank”), and the Bank’s wholly-owned subsidiaries, NSB Services Corp. and NSB Realty Trust (collectively the “Company”). All significant intercompany accounts and transactions have been eliminated in consolidation.

In the opinion of management, all adjustments (consisting solely of normal and recurring adjustments) necessary for the fair presentation of the consolidated balance sheets and the consolidated statements of comprehensive income for the unaudited periods presented have been included. The results of operations and other data presented for the three months ended March 31, 2026 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2026 or for any other period. Whenever necessary, certain prior year amounts are reclassified to conform to the current year presentation.
In preparing the unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheets and for the periods indicated in the consolidated statements of comprehensive income. Material estimates that are particularly susceptible to change are: the allowance for credit losses and the valuation allowance against deferred tax assets. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates.

Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for the preparation of interim financial statements. 
The consolidated financial statements presented should be read in conjunction with the audited consolidated financial statements and notes to consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC.

Contractual maturities for mortgage-backed securities are not included above, as expected maturities on mortgage-backed securities may differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without penalties.

Certain securities available-for-sale are pledged or encumbered to secure borrowings under pledge agreements and repurchase agreements and for other purposes required by law. At March 31, 2026, and December 31, 2025, the fair value of debt securities available-for-sale that were pledged to secure borrowings and deposits was $704.0 million and $686.3 million, respectively.

For the three months ended March 31, 2026, the Company had no proceeds on sales of debt securities available-for-sale, with no gross realized gains and gross realized losses of $2,000 related to calls of securities. For the three months ended March 31, 2025, the Company had no proceeds on sales of debt securities available-for-sale, with no gross realized gains or losses. The Company recognized net losses of $254,000 and $299,000 on its trading securities portfolio during the three months ended March 31, 2026 and 2025, respectively.

Gross unrealized losses on mortgage-backed securities and other debt securities available-for-sale, and the estimated fair value of the related securities, aggregated by security category and length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2026, and December 31, 2025, were as follows (in thousands):

The Company held 90 pass-through mortgage-backed securities issued or guaranteed by GSEs, 61 REMIC mortgage-backed securities issued or guaranteed by GSEs, one corporate bond, and one U.S. Government agency security that were in a continuous unrealized loss position of twelve months or greater at March 31, 2026. There was 14 pass-through mortgage-backed security issued or guaranteed by a GSE, three REMIC mortgage-backed securities issued or guaranteed by GSEs, one municipal bond, and one corporate bond that were in an unrealized loss position of less than twelve months at March 31, 2026. Substantially all securities referred to above were rated investment grade at March 31, 2026.

Available-for-sale debt securities in unrealized loss positions are evaluated for impairment related to credit losses on a quarterly basis. In performing an assessment of whether any decline in fair value is due to a credit loss, the Company considers the extent to which the fair value is less than the amortized cost, changes in credit ratings, any adverse economic conditions, as well as all relevant information at the individual security level such as credit deterioration of the issuer or collateral underlying the security. In assessing the impairment, the Company compares the present value of cash flows expected to be collected with the amortized cost basis of the security. If it is determined that the decline in fair value was due to credit losses, an allowance for credit losses is recorded, limited to the amount the fair value is less than amortized cost basis. The Company did not record any allowance for credit losses on its available-for-sale debt securities as of March 31, 2026 or December 31, 2025.

12
NORTHFIELD BANCORP, INC.
Notes to Unaudited Consolidated Financial Statements - (Continued)
The non-credit related decrease in the fair value, such as a decline due to changes in market interest rates, is recorded in other comprehensive income, net of tax. The Company also assesses its intent to sell the securities (as well as the likelihood of a near-term recovery). If the Company intends to sell an available-for-sale debt security or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, the debt security is written down to its fair value and the write down is charged to the debt security’s fair value at the reporting date with any incremental impairment reported in earnings.

The Company has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Accrued interest receivable associated with debt securities available-for-sale totaled $4.1 million and $4.2 million at March 31, 2026, and December 31, 2025, respectively, and was reported in accrued interest receivable on the consolidated balance sheets. The Company elected not to measure an allowance for credit losses on accrued interest receivable as an allowance on possible uncollectible accrued interest is not warranted.

At March 31, 2026, and December 31, 2025, debt securities held-to-maturity with a carrying value of $8.1 million and $6.7 million, respectively, were pledged to secure borrowings and deposits.

Gross unrealized losses on mortgage-backed securities held-to-maturity, and the estimated fair value of the related securities, aggregated by security category and length of time that individual securities have been in a continuous unrealized loss position at March 31, 2026, and December 31, 2025, were as follows (in thousands):

The Company held nine pass-through mortgage-backed debt securities held-to-maturity issued or guaranteed by GSEs that were in a continuous unrealized loss position of twelve months or greater at March 31, 2026.

The Company's held-to-maturity securities are residential mortgage-backed securities issued by Ginnie Mae, Freddie Mac and Fannie Mae, and it is expected that the securities will not be settled at prices less than the amortized cost bases of the securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. Government. Accordingly, no allowance for credit losses has been recorded for these securities.

The Company has made the accounting policy election to exclude accrued interest receivable on held-to-maturity securities from the estimate of credit losses. Accrued interest receivable associated with held-to-maturity securities totaling $29,000 and $30,000 at March 31, 2026, and December 31, 2025, respectively, was reported in accrued interest receivable on the consolidated balance sheets. The Company elected not to measure an allowance for credit losses on accrued interest receivable as an allowance on possible uncollectible accrued interest is not warranted.

Note 4 – Equity Securities

Equity securities totaled $5.0 million at both March 31, 2026, and December 31, 2025, and consisted of an investment in a private SBA loan fund (the “SBA Loan Fund”) recorded at net asset value. As the SBA Loan Fund operates as a private fund, its shares are not publicly traded and, therefore, has no readily determinable market value. The SBA Loan Fund was recorded at net asset value as a practical expedient for reporting fair value.

In addition to originating loans, the Company may acquire loans through portfolio purchases or acquisitions of other companies. Purchased loans that have evidence of more than insignificant credit deterioration since origination are deemed PCD loans. For PCD loans, each loan pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. PCD loans totaled $8.2 million at March 31, 2026, as compared to $8.3 million at December 31, 2025. The majority of the PCD loan balances were acquired as part of a Federal Deposit Insurance Corporation-assisted transaction. At March 31, 2026, PCD loans consisted of approximately 10% of one-to-four family residential loans, 21% of commercial real estate loans, 56% of commercial and industrial loans, and of 13% home equity loans. At December 31, 2025, PCD loans consisted of approximately 10% of one-to-four family residential loans, 21% of commercial real estate loans, 58% of commercial and industrial loans, and 11% of home equity loans.

Credit Quality Indicators

The Company monitors the credit quality of its loan portfolio on a regular basis. Credit quality is monitored by reviewing certain credit quality indicators. Management has determined that loan-to-value (“LTV”) ratios (at period end) and internally assigned credit risk ratings by loan type are the key credit quality indicators that best measure the credit quality of the Company’s loan receivables. LTV ratios used by management in monitoring credit quality are based on current period loan balances and original appraised values at the time of origination (unless a current appraisal has been obtained as a result of the loan being deemed impaired).

The Company maintains a credit risk rating system as part of the risk assessment of its loan portfolio. The Company’s lending officers are required to assign a credit risk rating to each loan in their portfolio at origination. This risk rating is reviewed periodically and adjusted if necessary. Quarterly, management presents monitored assets to the Loan Committee. In addition, the Company engages a third-party independent loan reviewer that performs semi-annual reviews of a sample of loans, validating the credit risk ratings assigned to such loans. The credit risk ratings play an important role in the establishment of the provision for credit losses on loans and the allowance for credit losses for loans held-for-investment. After determining the loss factor for each portfolio segment held-for-investment, the collectively evaluated for impairment balance of the held-for-investment portfolio is multiplied by the collectively evaluated for impairment loss factor for the respective portfolio segment in order to determine the allowance for loans collectively evaluated for impairment.

When assigning a credit risk rating to a loan, management utilizes the Bank’s internal nine-point credit risk rating system.

1.Strong
2.Good
3.Acceptable
4.Adequate
5.Watch
6.Special Mention
7.Substandard
8.Doubtful
9.Loss

Loans rated 1 to 5 are considered pass ratings. An asset is classified substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard assets have well defined weaknesses based on objective evidence, and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all of the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full highly questionable and improbable based on current circumstances. Assets classified as loss are those considered uncollectible and of such little value that their continuance as assets is not warranted. Assets which do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses, are required to be designated special mention.

Past Due and Non-Accrual Loans

Included in loans receivable held-for-investment are loans for which the accrual of interest income has been discontinued due to deterioration in the financial condition of the borrowers (excluding PCD loans). The recorded investment of these non-accrual loans was $21.0 million and $15.2 million at March 31, 2026, and December 31, 2025, respectively. Generally, originated loans are placed on non-accrual status when they become 90 days or more delinquent, or sooner if considered appropriate by management, and remain on non-accrual status until they are brought current, have six consecutive months of performance under the revised loan terms, and factors indicating reasonable doubt about the timely collection of payments no longer exist. Therefore, loans may be current in accordance with their loan terms, or may be less than 90 days delinquent and still be on non-accruing status.

When an individual loan no longer demonstrates the similar credit risk characteristics as other loans within its current segment, the Company evaluates each for expected credit losses on an individual basis. All non-accrual loans $500,000 and above and all loans designated as Troubled Debt Restructurings (“TDRs”) prior to the adoption of Accounting Standards Update (“ASU”) No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”) on January 1, 2023, are individually evaluated. See “Loan Modifications Made to Borrowers Experiencing Financial Difficulty” section below for more information. The non-accrual loans individually evaluated for impairment were $16.4 million and $8.8 million at March 31, 2026, and December 31, 2025, respectively. Loans on non-accrual status with principal balances less than $500,000, and therefore not meeting the Company's definition of an impaired loan, amounted to $4.6 million and $6.4 million at March 31, 2026, and December 31, 2025, respectively. Loans past due 90 days or more and still accruing interest were $455,000 and $925,000 at March 31, 2026, and December 31, 2025, respectively, and consisted of loans that are well-secured and in the process of collection.

The following tables set forth the detail, and delinquency status, of non-performing loans (non-accrual loans and loans past due 90 days or more and still accruing), net of deferred fees and costs, at March 31, 2026, and December 31, 2025, excluding PCD loans and non-accrual loans held-for sale (in thousands):

Collateral-Dependent Loans

Loans for which the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral are considered to be collateral-dependent loans. Collateral can have a significant financial effect in mitigating exposure to credit risk and, where there is sufficient collateral, an allowance for credit losses is not recognized or is minimal. For collateral-dependent loans, the allowance for credit losses is individually assessed based on the fair value of the collateral less estimated costs of sale. The Company's collateral-dependent loans are secured by real estate, inventory and equipment. Collateral values are generally based on appraisals, which are adjusted for changes in market indices. As of March 31, 2026, and December 31, 2025, the Company had $15.9 million and $8.4 million of collateral-dependent impaired loans, respectively. The collateral-dependent loans at March 31, 2026, consisted of $11.3 million of commercial real estate loans, $2.8 million of multifamily loans, $839,000 of commercial and industrial loans, and $949,000 of one-to-four family residential loans. For the three months ended March 31, 2026, there was no significant deterioration or changes in the collateral securing these loans.

Note 6 – Allowance for Credit Losses (“ACL”) on Loans

Allowance for Collectively Evaluated Loans Held-for-Investment

In estimating the quantitative component of the allowance on a collective basis, the Company uses a risk rating migration model which calculates an expected life of loan loss percentage for each loan by generating probability of default and loss given default metrics. These metrics are multiplied by the exposure at the potential default, taking into consideration estimated prepayments, to calculate the quantitative component of the ACL. The metrics are based on the migration of loans from performing to loss by credit risk rating or delinquency categories using historical life-of-loan analysis periods for each loan portfolio pool, and the severity of loss, based on the aggregate net lifetime losses incurred using the Company's own historical loss experience and comparable peer data loss history. The model's expected losses based on loss history are adjusted for qualitative adjustments to address risks that may not be adequately represented in the risk rating migration model. Among other things, these adjustments include and account for differences in: (i) changes in lending policies and procedures; (ii) changes in local, regional, national, and international economic and business conditions and developments that affect the collectability of our portfolio, including the condition of various market segments; (iii) changes in the experience, ability and depth of lending management and other relevant staff; (iv) changes in the quality of our loan review system; (v) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and (vi) the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio.

The Company utilizes a two-year reasonable and supportable forecast period after which estimated losses revert to historical loss experience immediately for the remaining life of the loan. In establishing its estimate of expected credit losses, the Company utilizes five externally-sourced forward-looking economic scenarios developed by Moody's Analytics (“Moody's”).

Management utilizes five different Moody's scenarios so as to incorporate uncertainties related to the economic environment. These scenarios, which range from more benign to more severe economic outlooks, include a “most likely outcome” (the “Baseline” scenario) and four less likely scenarios referred to as the “Upside” and “Downside” scenarios. Each scenario is assigned a weighting with a majority of the weighting placed on the Baseline scenario and lower weights placed on both the Upside and Downside scenarios. The weighting assigned by management is based on the economic outlook and available information at the reporting date. The model projects economic variables under each scenario based on detailed statistical analyses. The Company has identified and selected key variables that most closely correlated to its historical credit performance, which include: Gross domestic product, unemployment, and three collateral indices: the Commercial Property Price Index, the Commercial Property Price Apartment Index and the Case-Shiller Home Price Index.

Allowance for Individually Evaluated Loans

The Company measures specific reserves for individual loans that do not share common risk characteristics with other loans, consisting of all loans previously modified as TDRs (prior to the adoption of ASU 2022-02) and non-accrual loans with an outstanding balance of $500,000 or greater. Loans individually evaluated for impairment are assessed to determine whether the loan’s carrying value is not in excess of the estimated fair value of the collateral less cost to sell, if the loan is collateral-dependent, or the present value of the expected future cash flows, if the loan is not collateral-dependent. Management performs an evaluation of each individually evaluated loan and generally obtains updated appraisals as part of the evaluation. In addition, management adjusts estimated fair values down to appropriately consider recent market conditions, our willingness to accept a lower sales price to effect a quick sale, and costs to dispose of any supporting collateral. Determining the estimated fair value of underlying collateral (and related costs to sell) can be difficult in illiquid real estate markets and is subject to significant assumptions and estimates. Management employs an independent third-party management firm that specializes in appraisal preparation and review to ascertain the reasonableness of updated appraisals. Projecting the expected cash flows for TDRs (prior to the adoption of ASU 2022-02), which are not collateral-dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Individually evaluated loans that have no impairment losses are not considered for collective allowances described above. Upon adoption of ASU 2022-02, the Company no longer establishes a specific reserve for loan modifications to borrowers experiencing financial difficulty. Instead, these loan modifications are included in their respective pool and a historical loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses. At March 31, 2026, and December 31, 2025, the ACL for loans individually evaluated for impairment was $1.6 million and $1.2 million, respectively.

Allowance for Credit Losses – Off-Balance Sheet Exposures

An ACL for off-balance-sheet exposures represents an estimate of expected credit losses arising from off-balance sheet exposures such as loan commitments, standby letters of credit and unused lines of credit (loans already on the books). Commitments to fund unused lines of credit are agreements to lend additional funds to customers as long as there have been no violations of any of the conditions established in the agreements (original or restructured). Commitments to originate loans generally have a fixed expiration or other termination clauses, which may require payment of a fee. Since some of these loan commitments are expected to expire without being drawn upon, total commitments do not necessarily represent future cash requirements. The reserve for off-balance sheet exposures is determined using the Current Expected Credit Losses (“CECL”) reserve factor in the related funded loan segment, adjusted for an average historical funding rate. The allowance for credit losses for off-balance sheet credit exposures is recorded in other liabilities on the consolidated balance sheets and the corresponding provision is included in other non-interest expense.

The table below summarizes the allowance for credit losses for off-balance sheet credit exposures as of, and for, the three months ended March 31, 2026, and March 31, 2025 (in thousands):

Note 8 – Subordinated Debt

On June 17, 2022, the Company issued $62.0 million in aggregate principal amount of fixed-to-floating subordinated notes (the “Notes”) to certain institutional investors. The Notes mature on June 30, 2032, unless redeemed earlier. The Notes initially bear interest, payable semi-annually in arrears, at a fixed rate of 5.00% per annum until June 30, 2027. Beginning June 30, 2027 and until maturity or redemption, the interest rate applicable to the outstanding principal amount of the Notes due will reset quarterly to an interest rate per annum equal to the then current three-month Secured Overnight Financing Rate plus 200 basis points, payable quarterly in arrears. The Company has the option to redeem the Notes, at par and in whole or in part, beginning on June 30, 2027 and to redeem the Notes at any time in whole upon certain other events. Any redemption of the Notes will be subject to prior regulatory approval to the extent required. Debt issuance costs totaled $1.1 million and are being amortized to maturity. At March 31, 2026, and December 31, 2025, subordinated debt totaled $61.7 million and $61.7 million, respectively, which included $279,000 and $335,000, respectively, of unamortized debt issuance costs. The Company recognized amortization expense of $56,000 for the three months ended March 31, 2026 and 2025.

Note 10 – Fair Value Measurements
The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of March 31, 2026, and December 31, 2025, by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (“FASB”) ASC. Financial assets and liabilities are classified in their entirety based on the level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

•Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

•Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means.

•Level 3 Inputs – Significant unobservable inputs that reflect the Company’s own assumptions that market participants would use in pricing the assets or liabilities.

The methods of determining the fair value of assets and liabilities presented in this note are consistent with our methodologies disclosed in Note 16 to the Consolidated Financial Statements of the Company’s 2025 Annual Report on Form 10-K.

The valuation techniques described below were used to measure fair value of financial instruments in the tables below on a recurring basis and a non-recurring basis at March 31, 2026 and December 31, 2025.
Debt Securities Available for Sale: The estimated fair values for mortgage-backed securities, corporate, and other debt securities are obtained from an independent nationally recognized third-party pricing service. The estimated fair values are derived primarily from cash flow models, which include assumptions for interest rates, credit losses, and prepayment speeds. Broker/dealer quotes are utilized as well, when such quotes are available and deemed representative of the market. The significant inputs utilized in the cash flow models are based on market data obtained from sources independent of the Company (Observable Inputs), and are therefore classified as Level 2 within the fair value hierarchy. There were no transfers of securities between Level 1 and Level 2 during the three months ended March 31, 2026 or March 31, 2025.
Trading Securities: Fair values are derived from quoted market prices in active markets. The assets consist of publicly traded mutual funds.

Equity Securities: Fair values of equity securities consisting of publicly traded mutual funds are derived from quoted market prices in active markets.

Loans Individually Evaluated for Impairment: At March 31, 2026, and December 31, 2025, the Company had loans individually evaluated for impairment (excluding PCD loans) with outstanding principal balances of $10.7 million and $10.8 million, respectively, which were recorded at their estimated fair value of $6.7 million and $7.2 million, respectively. The Company recorded a net increase in the specific reserve for impaired loans of $389,000 and $645,000 for the three months ended March 31, 2026, and March 31, 2025, respectively. Net charge-offs of $1.4 million and $2.8 million were recorded for the three months ended March 31, 2026, and March 31, 2025, respectively, utilizing Level 3 inputs. For purposes of estimating the fair value of impaired loans, management utilizes independent appraisals, if the loan is collateral-dependent, adjusted downward by management, as necessary, for changes in relevant valuation factors subsequent to the appraisal date, or the present value of expected future cash flows for non-collateral dependent loans and TDRs.

Other Real Estate Owned: At March 31, 2026, and December 31, 2025, the Company had no assets acquired through foreclosure.

In addition, the Company may be required, from time to time, to measure the fair value of certain other financial assets on a nonrecurring basis in accordance with U.S. GAAP. The adjustments to fair value usually result from the application of lower-of-cost-or-market accounting or write downs of individual assets.

Fair Value of Financial Instruments:
The FASB ASC Topic for Financial Instruments requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The following methods and assumptions were used to estimate the fair value of other financial assets and financial liabilities not already discussed above:

33
NORTHFIELD BANCORP, INC.
Notes to Unaudited Consolidated Financial Statements - (Continued)
(a)     Cash and Cash Equivalents
Cash and cash equivalents are short-term in nature with original maturities of three months or less; the carrying amount approximates fair value. Certificates of deposit having original terms of six-months or less; the carrying value generally approximates fair value. Certificates of deposit with an original maturity of six months or greater; the fair value is derived from discounted cash flows.

(b)    Debt Securities (Held-to-Maturity)
The estimated fair values for substantially all of our securities are obtained from an independent nationally recognized pricing service. The independent pricing service utilizes market prices of same or similar securities whenever such prices are available. Prices involving distressed sellers are not utilized in determining fair value. Where necessary, the independent third-party pricing service estimates fair value using models employing techniques such as discounted cash flow analysis. The assumptions used in these models typically include assumptions for interest rates, credit losses, and prepayments, utilizing market observable data where available.

(c)    Investments in Equity Securities at Net Asset Value Per Share
The Company uses net asset value as a practical expedient to record its investment in a private SBA Loan Fund since the shares in the fund are not publicly traded, do not have a readily determinable fair value and the net asset value per share is calculated in a manner consistent with the measurement principles of an investment company.

(d)    Federal Home Loan Bank of New York Stock
Federal Home Loan Bank of New York (“FHLBNY”) stock is carried at cost since this is the amount for which it could be redeemed. Due to restrictions placed on the transferability of FHLBNY stock it is not practical to determine the fair value as there is no active market for this stock.

(e)    Loans (Held-for-Investment)
Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as originated and purchased, and further segregated by residential mortgage, construction, land, multifamily, commercial and consumer. Each loan category is further segmented into amortizing and non-amortizing and fixed and adjustable-rate interest terms and by performing and non-performing categories. The fair value of loans is estimated using a discounted cash flow analysis. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and non-performance risk of the loans.

(f)    Loans (Held-for-Sale)
Held-for-sale loans are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore fair value is equal to carrying value.
 
(g)    Deposits
The fair value of deposits with no stated maturity, such as interest and non-interest-bearing demand deposits, savings, NOW and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities.

(h)    Commitments to Extend Credit and Standby Letters of Credit
The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of off-balance sheet commitments is insignificant and therefore not included in the following table.

 (i)    Borrowings
The fair value of borrowed funds is estimated by discounting future cash flows based on rates currently available for debt with similar terms and remaining maturity.
34
NORTHFIELD BANCORP, INC.
Notes to Unaudited Consolidated Financial Statements - (Continued)
(j)    Advance Payments by Borrowers for Taxes and Insurance
Advance payments by borrowers for taxes and insurance have no stated maturity; the fair value is equal to the amount currently payable.

(k)    Derivatives
The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.

The estimated fair values of the Company’s significant financial instruments at March 31, 2026, and December 31, 2025, are presented in the following tables (in thousands):

Limitations
Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
Fair value estimates are based on existing on-and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.
Note 11 – Earnings Per Share

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during the period. For purposes of calculating basic earnings per share, weighted average common shares outstanding excludes unallocated employee stock ownership plan (“ESOP”) shares that have not been committed for release and unvested restricted stock and performance-based restricted stock units.

Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options were exercised and converted into common stock and unvested shares of restricted stock and performance-based restricted stock units vested. These potentially dilutive shares are then included in the weighted average number of shares outstanding for the period using the treasury stock method. When applying the treasury stock method, the assumed proceeds from option exercises and the average unamortized compensation costs related to unvested shares of restricted stock, performance-based restricted stock units and stock options were added. This sum was then divided by the average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share.

Note 12 – Leases

The Company’s leases primarily relate to real estate property for branches and office space with terms extending from two months up to 28.8 years. At March 31, 2026, all of the Company’s leases are classified as operating leases, which are required to be recognized on the consolidated balance sheets as a right-of-use asset and a corresponding lease liability.

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets and operating lease liabilities on the consolidated balance sheets. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recorded at the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate, at lease inception, over a similar term in determining the present value of lease payments. Certain leases include options to renew, with one or more renewal terms ranging from five to ten years. If the exercise of a renewal option is considered to be reasonably certain, the Company includes the extended term in the calculation of the right-of-use asset and lease liability.

At March 31, 2026, the Company’s operating lease right-of-use assets and operating lease liabilities included on the consolidated balance sheet were $24.6 million and $28.3 million, respectively. At December 31, 2025, the Company’s operating lease right-of-use assets and operating lease liabilities included on the consolidated balance sheet were $25.8 million and $29.6 million, respectively. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Variable lease payments include common area maintenance charges, real estate taxes, repairs and maintenance costs and utilities. Operating and variable lease expenses are recorded in occupancy expense on the consolidated statements of comprehensive income.
Supplemental lease information at or for the three months ended March 31, 2026, and March 31, 2025 is as follows (dollars in thousands):

Note 13 – Derivatives

The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan-related transaction and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The interest rate swap agreement which the Company executed with the commercial borrower is collateralized by the borrower’s commercial real estate financed by the Company. The collateral exceeds the maximum potential amount of future payments under the credit derivative. As these interest rate swaps do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings.
At March 31, 2026, the Company had 18 interest rate swaps with a notional amount of $141.6 million. At December 31, 2025, the Company had 18 interest rate swaps with a notional amount of $142.7 million. The Company recorded no fee income related to swaps for three months ended March 31, 2026 and 2025.

Note 14 - Segment Information
The Company's reportable segment is determined by the Chief Operating Decision Maker (“CODM”), who is the President and Chief Executive Officer. The CODM's decision is based upon information provided about the Company's products and services offered, primarily banking operations, originating loans and offering a variety of deposit products. The segment is also distinguished by the level of information provided by the CODM, who uses such information to review performance of various components of the business (such as branches) which are then aggregated if operating performance, products and services, and customers are similar. The CODM will evaluate the performance of the Company's business components such as by evaluating revenue streams, significant expenses, and budget to actual results in assessing the Company's segment and in the determination of allocating resources. The CODM uses the revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The CODM uses consolidated net income to benchmark the Company against its competitors. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessment performance and in establishing compensation. Loans and investments provide the revenues in the banking operations. Interest expense, provisions for credit losses, and payroll provide the significant expenses in the banking operations. The Company's operations are all domestic.

ITEM 2.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Merger
On January 31, 2026, Northfield Bancorp, Inc. (“Bancorp”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Columbia Financial, Inc., a Delaware corporation (“Columbia Financial”), Columbia Financial, Inc., a newly-formed Maryland corporation (the “Holding Company”), and Columbia Bank MHC, the parent mutual holding company of Columbia Financial (the “MHC”). Pursuant to the terms of the Merger Agreement and subject to the conditions set forth therein, immediately following the completion of the mutual-to-stock conversion of the MHC (the “Conversion”), Bancorp will merge with and into the Holding Company (the “Merger”), with the Holding Company continuing as the surviving corporation. Immediately following the completion of the Merger, the Holding Company will cause Northfield Bank to merge with and into Columbia Bank, the subsidiary of the Holding Company, with Columbia Bank continuing as the surviving institution.
Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Bancorp's common stock, par value $0.01 per share (the “Northfield Common Stock”), issued and outstanding immediately before the Effective Time, other than certain shares held by Columbia Financial, the Holding Company, the MHC or the Company, will be converted, at the election of the holder, into the right to receive either shares of Holding Company Common Stock or cash (the “Cash Consideration”), as follows: (i) if the final appraised pro forma market value of the Holding Company, as determined by an independent appraiser (such appraisal, the “Independent Valuation”), immediately prior to the completion of the Conversion (the “Final Independent Appraisal”) is less than $2.3 billion, 1.425 shares of Holding Company Common Stock (the “Merger Exchange Ratio”) or $14.25 in cash (the “Per Share Cash Consideration”); (ii) if the Final Independent Valuation is equal to or greater than $2.3 billion and less than $2.6 billion, the Merger Exchange Ratio will be increased to 1.450 shares of Holding Company Common Stock and the Per Share Cash Consideration will be increased to $14.50; or (iii) if the Final Independent Valuation is greater than $2.6 billion, the Merger Exchange Ratio will be increased to 1.465 shares of Holding Company Common Stock and the Per Share Cash Consideration will be increased to $14.65. No more than 30% of the shares of Northfield Common Stock issued and outstanding as of the Effective Time (excluding shares of Northfield Common Stock to be canceled as provided the Merger Agreement) will be converted into the aggregate Cash Consideration.
The Merger remains subject to the receipt of certain depositor, stockholder and regulatory approvals and the satisfaction of other customary closing conditions. The Merger is expected to close early in the third quarter of 2026.
The foregoing description of the proposed Merger and the Merger Agreement is not complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which was filed as Exhibit 2.1 to the Bancorp's Current Report on Form 8-K, dated January 31, 2026, filed with the Securities and Exchange Commission on February 2, 2026.

Critical Accounting Policies
 
Note 1 to the Company’s Audited Consolidated Financial Statements for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K, as supplemented by this report, contains a summary of our significant accounting policies. Various elements of these accounting policies are subject to estimation techniques, valuation assumptions, and other subjective assessments. Certain assets are carried on the consolidated balance sheets at estimated fair value or the lower of cost or estimated fair value. Policies with respect to the methodologies used to determine the allowance for credit losses on loans are the most critical accounting policies because they are important to the presentation of the Company’s financial condition and results of operations, involve a higher degree of complexity, and require management to make subjective judgments which often require assumptions or estimates about highly uncertain matters. The use of different judgments, assumptions, and estimates could result in material differences in the results of operations or financial condition. These critical accounting policies and their application are reviewed periodically and, at least annually, with the Audit Committee of the Board of Directors.
The accounting estimates relating to the allowance for credit losses remain "critical accounting estimates" for the following reasons:
•Changes in the provision for credit losses can materially affect our financial results;
•Estimates relating to the allowance for credit losses require us to utilize a reasonable and supportable forecast period based upon forward-looking economic scenarios in order to estimate probability of default and loss given default rates, which our Current Expected Credit Losses (“CECL”) methodology encompasses;
•The allowance for credit losses is influenced by factors outside of our control such as industry and business trends, as well as economic conditions such as trends in housing prices, interest rates, gross domestic product, inflation, and unemployment; and
•Judgment is required to determine whether the models used to generate the allowance for credit losses produce an estimate that is sufficient to encompass the current view of lifetime expected credit losses.

Our estimation process is subject to risks and uncertainties, including a reliance on historical loss and trend information that may not be representative of current conditions and indicative of future performance. Changes in such estimates could significantly impact our allowance and provision for credit losses. Accordingly, our actual credit loss experience may not be in line with our expectations.

For a further discussion of our critical accounting policies, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2025.
Overview
This overview highlights selected information and may not contain all the information that is important to you in understanding our performance during the periods presented. For a more complete understanding of trends, events, commitments, uncertainties, liquidity, capital resources, and critical accounting estimates, you should read this entire document carefully, as well as our Annual Report on Form 10-K for the year ended December 31, 2025.
Net income was $11.8 million for the three months ended March 31, 2026, as compared to $7.9 million for the three months ended March 31, 2025. The increase in net income for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, was primarily due to an increase in net interest income, driven by lower funding costs and higher yields on loans and securities, as well as a decrease in the provision for credit losses on loans, partially offset by an increase in merger-related expenses. Net income for the three months ended March 31, 2026, included non-tax deductible merger-related expenses of $1.7 million, or $0.04 per share, related to the pending merger with Columbia Financial, Inc. Basic and diluted earnings per common share were $0.30 for the three months ended March 31, 2026, compared to basic and diluted earnings per common share of $0.19 for the three months ended March 31, 2025. For the three months ended March 31, 2026, our return on average assets was 0.85%, as compared to 0.56% for the three months ended March 31, 2025. For the three months ended March 31, 2026, our return on average stockholders’ equity was 6.93% as compared to 4.52% for the three months ended March 31, 2025.

Comparison of Financial Condition at March 31, 2026 and December 31, 2025
Total assets decreased by $18.8 million, or 0.3%, to $5.74 billion at March 31, 2026, from $5.75 billion at December 31, 2025. The decrease was primarily due to decreases in loans held-for-investment, of $48.8 million, or 1.3%, available-for-sale debt securities of $33.9 million, or 2.4%, other assets of $7.1 million, or 20.2%, and Federal Home Loan Bank of New York (“FHLBNY”) stock of $4.4 million, or 9.4%, partially offset by an increase in cash and cash equivalents of $75.7 million, or 46.1%.
Cash and cash equivalents increased by $75.7 million, or 46.1%, to $239.6 million at March 31, 2026, from $164.0 million at December 31, 2025. Balances fluctuate based on the timing of receipt of security and loan repayments and the redeployment of cash into higher-yielding assets such as loans and securities, or the funding of deposit outflows or borrowing maturities.
The Company’s available-for-sale debt securities portfolio decreased by $33.9 million, or 2.4%, to $1.38 billion at March 31, 2026, from $1.41 billion at December 31, 2025. The decrease was primarily attributable to paydowns and maturities. At March 31, 2026, $1.33 billion of the portfolio consisted of residential mortgage-backed securities issued or guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae. In addition, the Company held $47.8 million in corporate bonds, substantially all of which were investment grade, $614,000 in municipal bonds and $539,000 in U.S. Government agency securities at March 31, 2026. Unrealized losses, net of tax, on available-for-sale debt securities and held-to-maturity securities approximated $10.8 million and $244,000, respectively, at March 31, 2026, and $10.5 million and $206,000, respectively, at December 31, 2025. The effective duration of the securities portfolio at March 31, 2026 was 1.64 years.
Equity securities were $5.0 million at both March 31, 2026 and December 31, 2025. At March 31, 2026, equity securities were primarily comprised of an investment in a Small Business Administration ("SBA") Loan Fund. This investment in the SBA Loan Fund is utilized by Northfield Bank (the "Bank") to satisfy its Community Reinvestment Act lending requirements.
Loans held-for-investment decreased by $48.8 million, or 1.3%, to $3.81 billion at March 31, 2026 from $3.86 billion at December 31, 2025, primarily due to a decrease in multifamily real estate loans. The decrease in multifamily loan balances reflects the Company's continued strategic focus on managing concentration risk within its commercial and multifamily real estate loan portfolios, while maintaining disciplined loan pricing. Multifamily loans decreased $47.3 million, or 2.0%, to $2.31 billion at March 31, 2026 from $2.36 billion at December 31, 2025. Commercial real estate loans decreased $9.8 million, or 1.1%, to $901.6 million at March 31, 2026 from $911.4 million at December 31, 2025. Home equity and lines of credit decreased $2.9 million, or 1.4%, to $195.7 million at March 31, 2026 from $198.6 million at December 31, 2025. One-to-four family residential loans decreased $901,000, or 0.5%, to $164.2 million at March 31, 2026 from $165.1 million at December 31, 2025. Partially offsetting these decreases were increases in commercial and industrial loans of $6.8 million, or 4.1%, to $173.0 million at March 31, 2026 from $166.2 million at December 31, 2025, as a result of an increase in originations related to new lenders. Construction and land loans increased $5.6 million, or 12.7%, to $50.2 million at March 31, 2026 from $44.5 million at December 31, 2025, primarily attributable to advances on existing loans.

The Company obtains an appraisal of the real estate collateral securing a commercial real estate loan prior to originating the loan. The appraised value is used to calculate the ratio of the outstanding loan balance to the value of the real estate collateral, or loan-to-value ratio ("LTV"). The original appraisal is used to monitor the LTVs within the commercial real estate portfolio unless an updated appraisal is received, which may happen for a variety of reasons, including but not limited to payment delinquency, additional loan requests using the same collateral, and loan modifications. The following table presents the ranges in the LTVs of our commercial mortgage loans at March 31, 2026:

As of March 31, 2026, non-owner occupied commercial real estate loans (as defined by regulatory guidance) to total risk-based capital was estimated at approximately 368%. Management believes that Northfield Bank (the “Bank”) maintains appropriate risk management practices including risk assessments, board-approved underwriting policies and related procedures, which includes monitoring Bank portfolio performance, performing market analysis (economic and real estate), and stressing of the Bank’s commercial real estate portfolio under severe, adverse economic conditions. Although management believes the Bank has implemented appropriate policies and procedures to manage its commercial real estate concentration risk, the Bank’s regulators could require it to implement additional policies and procedures or could require it to maintain higher levels of regulatory capital, which might adversely affect its loan originations, the Company's ability to pay dividends, and overall profitability.
Our real estate portfolio includes credit risk exposure to loans collateralized by office buildings and multifamily properties in New York subject to some form of rent regulation limiting rent increases for rent-stabilized multifamily properties. At March 31, 2026, office-related loans represented $177.3 million, or 4.7%, of our total loan portfolio, with an average balance of $1.8 million (although we have originated these type of loans in amounts substantially greater than this average) and a weighted average loan-to-value ratio of 57%. Approximately 38% were owner-occupied. The geographic locations of the properties collateralizing our office-related loans are: 50.6% in New York, 47.9% in New Jersey and 1.5% in Pennsylvania. At March 31, 2026, our largest office-related loan had a principal balance of $85.7 million (with a net active principal balance for the Bank of $28.6 million as we have a 33.3% participation interest), was secured by an office facility located in Staten Island, New York, and was performing in accordance with its original contractual terms. At March 31, 2026, multifamily loans that have some form of rent stabilization or rent control totaled $415.9 million, or 10.9% of our total loan portfolio, with an average balance of $1.7 million (although we have originated these type of loans in amounts substantially greater than this average) and a weighted average loan-to-value ratio of 50%. At March 31, 2026, our largest rent-regulated loan had a principal balance of $16.3 million, was secured by an apartment building located in Staten Island, New York, and was performing in accordance with its original contractual terms. Management continues to closely monitor its office and rent-regulated portfolios. For further details on our rent-regulated multifamily portfolio see “Asset Quality”.
Purchase credit-deteriorated (“PCD”) totaled $8.2 million and $8.3 million at March 31, 2026 and December 31, 2025, respectively. The majority of the remaining PCD loan balance consists of loans acquired as part of a Federal Deposit Insurance Corporation-assisted transaction. The Company accreted interest income of $224,000 attributable to PCD loans for the three months ended March 31, 2026, compared to $223,000 for the three months ended March 31, 2025, respectively. PCD loans had an allowance for credit losses of approximately $2.5 million at March 31, 2026.
FHLBNY stock decreased by $4.4 million, or 9.4%, to $42.2 million at March 31, 2026, from $46.6 million at December 31, 2025. The decrease in FHLBNY stock directly correlates with lower short-term borrowing balances at March 31, 2026, as compared to December 31, 2025.
Other assets decreased by $7.1 million, or 20.2%, to $28.1 million at March 31, 2026, from $35.2 million at December 31, 2025. The decrease was primarily attributable to a decrease in tax assets (deferred and receivables) and proceeds due from broker.
Total liabilities decreased $23.4 million, or 0.5%, to $5.04 billion at March 31, 2026, from $5.06 billion at December 31, 2025. The decrease was primarily attributable to a decrease in borrowings of $98.0 million, partially offset by an increase in deposits of $72.8 million. The Company routinely utilizes brokered deposits and borrowed funds to manage interest rate risk, the cost of interest-bearing liabilities, and funding needs related to loan originations and deposit activity.
Deposits, excluding brokered deposits, increased $83.3 million, or 2.1%, to $4.06 billion at March 31, 2026 as compared to $3.98 billion at December 31, 2025. The increase in deposits, excluding brokered deposits, was primarily attributable to an increase of $99.8 million in transaction accounts, and $13.7 million in savings accounts, partially offset by decreases of $20.1 million in time deposits, and $10.1 million in money market accounts. Growth in transaction and savings accounts was primarily the result of the Company's focus on growing low/no cost checking deposits. Northfield Bank does not compete with high rate time deposits offered by competitors, which accounted for the decrease in that product category. Estimated gross uninsured deposits at March 31, 2026 were $2.07 billion, which included fully collateralized uninsured governmental deposits and intercompany deposits of $1.11 billion, leaving estimated uninsured deposits of approximately $957.6 million, or 23.4%, of total deposits. At December 31, 2025, estimated uninsured deposits, excluding fully collateralized uninsured governmental deposits and intercompany deposits, totaled $952.9 million, or 23.7% of total deposits.
45
Borrowed funds decreased to $863.9 million at March 31, 2026, from $961.9 million at December 31, 2025. The decrease in borrowings was primarily due to a $40.0 million decrease in borrowings under an overnight line of credit, and a $58.0 million decrease in other borrowings. We were able to reduce our reliance on borrowings due to an increase in deposits. Management utilizes borrowings to mitigate interest rate risk, for short-term liquidity, and to a lesser extent from time to time, as part of leverage strategies.
The following table sets forth term borrowing maturities (excluding overnight borrowings, floating rate advances, and subordinated debt) and the weighted average rate by year at March 31, 2026 (dollars in thousands):

Total stockholders’ equity increased by $4.6 million to $694.7 million at March 31, 2026, from $690.1 million at December 31, 2025. The increase was attributable to net income of $11.8 million for the three months ended March 31, 2026, and a $500,000 increase in equity award activity, partially offset by $5.3 million in dividend payments, and a $2.4 million increase in accumulated other comprehensive loss associated with a decrease in the estimated fair value of our debt securities available-for-sale portfolio.
Comparison of Operating Results for the Three Months Ended March 31, 2026 and 2025
Net Income. Net income was $11.8 million and $7.9 million for the three months ended March 31, 2026 and March 31, 2025, respectively. Significant variances from the comparable prior year period are as follows: a $5.2 million increase in net interest income, a $2.3 million decrease in the provision for credit losses on loans, a $390,000 increase in non-interest income, a $1.8 million increase in non-interest expense, and a $2.1 million increase in income tax expense.
Interest Income. Interest income increased $2.8 million, or 4.7%, to $62.9 million for the three months ended March 31, 2026, from $60.1 million for the three months ended March 31, 2025, primarily due to a 19 basis point increase in the yield on interest-earning assets, which increased to 4.69% for the three months ended March 31, 2026, from 4.50% for the three months ended March 31, 2025, due to higher yields on mortgage-backed securities, and a $27.1 million, or 0.5%, increase in the average balance of interest-earning assets. The increase in the average balance of interest-earning assets was primarily due to increases in the average balance of mortgage-backed securities of $218.6 million and the average balance of interest-earning deposits in financial institutions of $52.4 million, partially offset by decreases in the average balance of loans of $180.4 million and the average balance of other securities of $67.4 million. The Company accreted interest income related to PCD loans of $224,000 for the three months ended March 31, 2026, as compared to $223,000 for the three months ended March 31, 2025. Interest income for the three months ended March 31, 2026, also included loan prepayment income of $74,000 as compared to $245,000 for the three months ended March 31, 2025.
Interest Expense. Interest expense decreased $2.4 million, or 8.3%, to $25.9 million for the three months ended March 31, 2026, as compared to $28.3 million for the three months ended March 31, 2025. The decrease was primarily due to a decrease in the cost of interest-bearing liabilities, which decreased by 22 basis points to 2.52% for the three months ended March 31, 2026, from 2.74% for the three months ended March 31, 2025, and a decrease in the average balance of interest-bearing liabilities of $2.4 million, or 0.1%. The decrease in the cost of interest-bearing liabilities was driven primarily by a 34 basis point decrease in the cost of interest-bearing deposits to 2.17% from 2.51%, attributable to a shift to lower cost deposit sources such as negotiable orders of withdrawal and savings accounts. Partially offsetting the decrease was an 11 basis point increase in the cost of borrowed funds to 3.78% from 3.67%, attributable to increased utilization of short-term Federal Home Loan Bank advances. The average balance of interest-bearing liabilities decreased primarily due to an $84.5 million, or 2.5%, decrease in the average balance of interest-bearing deposits, primarily in certificates of deposit, partially offset by an $82.0 million, or 11.8%, increase in the average balance of borrowed funds.
Net Interest Income. Net interest income for the three months ended March 31, 2026, increased $5.2 million, or 16.3%, to $37.0 million, from $31.8 million for the three months ended March 31, 2025, primarily due to a 38 basis point increase in net interest margin to 2.76% from 2.38% for the three months ended March 31, 2025. The increase in net interest margin was primarily due to higher yields on loans and mortgage-backed securities, coupled with a decrease in the cost of interest-bearing liabilities.
46

Provision for Credit Losses. The provision for credit losses on loans decreased by $2.3 million to $247,000 for the three months ended March 31, 2026, compared to $2.6 million for the three months ended March 31, 2025, primarily due to a decrease in general reserves, partially offset by an increase in specific reserves. The decrease in general reserves was related to a decline in loan balances and lower net charge-offs, partially offset by an increase in qualitative reserves in our multifamily portfolio. The increase in specific reserves was related to one collateral-dependent commercial real estate loan. Net charge-offs were $1.4 million for the three months ended March 31, 2026, as compared to $2.8 million for the three months ended March 31, 2025, and included charge-offs of $1.3 million and $2.4 million on small business unsecured commercial and industrial loans for the three months ended March 31, 2026 and 2025, respectively. Management continues to closely monitor the small business unsecured commercial and industrial loan portfolio, which totaled $17.6 million at March 31, 2026.
Non-interest Income. Non-interest income increased by $390,000, or 12.9%, to $3.4 million for the three months ended March 31, 2026, compared to $3.0 million for the three months ended March 31, 2025. The increase was primarily due to an increase in income on bank-owned life insurance of $252,000 and an $89,000 increase in fees and service charges for customer services.
Non-interest Expense. Non-interest expense increased by $1.8 million, or 8.5%, to $23.3 million for the three months ended March 31, 2026, compared to $21.4 million for the three months ended March 31, 2025. The increase was primarily due to a $1.7 million increase in merger expenses related to the pending Merger, and an $898,000 increase in employee compensation and benefits, primarily due to higher salary expense related to annual merit increases. Partially offsetting the increases were a $381,000 decrease in professional fees, primarily attributable to lower outsourced consulting and recruitment fees, a $170,000 decrease in credit loss expense/(benefit) for off-balance sheet exposure, and a $143,000 decrease in other non-interest expense. The decrease in credit loss expense/(benefit) for off-balance sheet exposure was due to a benefit of $67,000 recorded during the three months ended March 31, 2026, as compared to a provision of $103,000 recorded during the three months ended March 31, 2025, due to a decrease in the pipeline of loans committed and awaiting closing.
Income Tax Expense. The Company recorded income tax expense of $5.0 million for the three months ended March 31, 2026, compared to $2.9 million for the three months ended March 31, 2025. The effective tax rate for the three months ended March 31, 2026, was 29.8% compared to 27.0% for the three months ended March 31, 2025.

PCD Loans (Held-for-Investment)
The Company accounts for PCD loans at estimated fair value using discounted expected future cash flows deemed to be collectible on the date acquired. Based on its detailed review of PCD loans and experience in loan workouts, management has a reasonable expectation about the amount and timing of future cash flows and accordingly has classified PCD loans ($8.2 million at March 31, 2026 and $8.3 million at December 31, 2025, respectively) as accruing, even though they may be contractually past due. At March 31, 2026, 1.0% of PCD loans were past due 30 to 89 days, and 23.9% were past due 90 days or more, as compared to 4.0% and 23.2%, respectively, at December 31, 2025.

The increase in non-accrual commercial mortgage loans at March 31, 2026 as compared to December 31, 2025, was primarily due to one loan with an outstanding balance of $6.5 million that was placed on non-accrual status as it was 90 days past due at March 31, 2026. The loan is considered well secured by collateral property in New York with an appraised value of $13.1 million and is in the process of collection.
Other Real Estate Owned
At March 31, 2026, and December 31, 2025, the Company had no assets acquired through foreclosure.
Accruing Loans 30 to 89 Days Delinquent
Loans 30 to 89 days delinquent and on accrual status totaled $7.8 million and $11.4 million at March 31, 2026, and December 31, 2025, respectively.

Liquidity and Capital Resources
Liquidity. The objective of our liquidity management is to ensure the availability of sufficient funds to meet financial commitments and deposit withdrawals, to repay borrowings as they mature, and to fund new loans and investments as opportunities arise.
The Bank's primary sources of funds are deposits, principal and interest payments on loans and securities, borrowed funds, the proceeds from maturing securities and short-term investments, and to a lesser extent, proceeds from the sales of loans and securities, and wholesale borrowings. The scheduled amortization of loans and securities, as well as proceeds from borrowed funds, are predictable sources of funds. Other funding sources, however, such as deposit inflows and loan prepayments are greatly influenced by market interest rates, economic conditions, and competition. The Bank is a member of the Federal Home Loan Bank of New York (“FHLBNY”), which provides an additional source of short-term and long-term funding. The Bank also has short-term borrowing capabilities with the Federal Reserve Bank of New York (“FRBNY”). The Bank’s total short-term borrowed funds, excluding lease obligations, floating rate advances and an overnight line of credit, were $705.8 million at March 31, 2026, and had a weighted average interest rate of 3.76%. A total of $438.5 million of these borrowings will mature in less than one year. Short-term borrowed funds, excluding floating rate advances, were $763.8 million at December 31, 2025.

On June 17, 2022, the Company issued $62.0 million in aggregate principal amount of fixed to floating subordinated notes (the “Notes”). The Notes are non-callable for five years, have a stated maturity of June 30, 2032, and bear interest at a fixed rate of 5.00% until June 30, 2027. From July 2027 to the maturity date or early redemption date, the interest rate will reset quarterly to a level equal to the then current three-month Secured Overnight Financing Rate plus 200 basis points.

The Bank has the ability to obtain additional funding from the FHLBNY and FRBNY of approximately $1.73 billion utilizing unencumbered securities of $606.6 million, loans of $1.12 billion, and encumbered securities of $2.0 million at March 31, 2026. Additionally, the Bank has remaining borrowing capacity utilizing encumbered securities through the FRBNY Discount Window of $65.6 million. The Bank expects to have sufficient funds available to meet current commitments in the normal course of business.

We monitor our liquidity position on a daily basis. We anticipate that we will have sufficient funds to meet our current funding commitments. Based on our deposit retention experience and current pricing strategy, we anticipate that a significant portion of maturing time deposits will be retained. However, if a substantial portion of these deposits are not retained, we may utilize FHLB advances, the FRBNY Discount Window, brokered deposits, sell unencumbered securities or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense.

The Company has a diversified deposit base, and government deposits are collateralized by assets or letters of credit issued by the FHLBNY. Estimated gross uninsured deposits at March 31, 2026 were $2.07 billion. This total includes fully collateralized uninsured governmental deposits and intercompany deposits of $1.1 billion, leaving estimated net uninsured deposits of approximately $957.6 million, or 23.4% of total deposits. At December 31, 2025, estimated net uninsured deposits totaled $952.9 million, or 23.7% of total deposits.

Northfield Bancorp, Inc. (standalone) is a separate legal entity from the Bank and must provide for its own liquidity to pay dividends, repurchase its stock, and for other corporate purposes. Northfield Bancorp, Inc.'s primary source of liquidity is dividend payments from the Bank. At March 31, 2026, Northfield Bancorp, Inc. (standalone) had liquid assets of $6.6 million.

Capital Resources. Federal regulations require federally insured depository institutions to meet several minimum capital standards: a common equity Tier 1 capital to risk-based assets ratio of 4.5%, a Tier 1 capital to risk-based assets ratio of 6.0%, a total capital to risk-based assets of 8.0%, and a 4.0% Tier 1 capital to total assets leverage ratio. In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets in addition to the amount necessary to meet its minimum risk-based capital requirements.
    
52
The federal banking agencies developed a “Community Bank Leverage Ratio” (“CBLR”) (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A qualifying community bank that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies have approved 9% as the current minimum capital for the CBLR, with 8% as the minimum capital for the CBLR, effective July1, 2026. Northfield Bank and Northfield Bancorp have elected to opt into the CBLR framework. The CBLR replaced the risk-based and leverage capital requirements in the generally applicable capital rules.

At March 31, 2026, and December 31, 2025, as set forth in the following table, both Northfield Bank and Northfield Bancorp, Inc. exceeded all of the regulatory capital requirements to which they were subject at such dates.

Off-Balance Sheet Arrangements and Contractual Obligations
In the normal course of operations, the Company engages in a variety of financial transactions that, in accordance with U.S. GAAP, are not recorded in the financial statements. These transactions primarily relate to lending commitments. These arrangements are not expected to have a material impact on the Company's results of operations or financial condition.
Commitments to fund unused lines of credit are agreements to lend additional funds to customers as long as there have been no violations of any of the conditions established in the agreements (original or restructured). Commitments to originate loans generally have a fixed expiration or other termination clauses, which may require payment of a fee. Since some of these loan commitments are expected to expire without being drawn upon, total commitments do not necessarily represent future cash requirements. At March 31, 2026, the reserve for commitments to fund unused lines of credit recorded in accrued expenses and other liabilities was $223,000.

For further information regarding our off-balance sheet arrangements and contractual obligations, see "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Management of Market Risk
General. A majority of our assets and liabilities are monetary in nature. Consequently, our most significant form of market risk is interest rate risk. Our assets, consisting primarily of mortgage-related securities and loans, generally have longer maturities than our liabilities, which consist primarily of deposits and wholesale borrowings. As a result, a principal part of our business strategy involves managing interest rate risk and limiting the exposure of our net interest income to changes in market interest rates. Accordingly, our Board of Directors has established a Management Asset-Liability Committee, comprised of our Senior Vice President (“SVP”) & Chief Investment Officer and Treasurer, who chairs this Committee, our President & Chief Executive Officer, our Executive Vice President (“EVP”) & Chief Risk Officer, our EVP & Chief Financial Officer, our EVP & Chief Lending Officer, our EVP & Chief Branch Administration, Deposit Operations & Business Development Officer, and other officers and staff as necessary or appropriate. This committee is responsible for, among other things, evaluating the interest rate risk inherent in our assets and liabilities, for recommending to the Risk Committee of our Board of Directors the level of risk that is appropriate given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the guidelines approved by the Board of Directors.

We seek to manage our interest rate risk in order to minimize the exposure of our earnings and capital to changes in interest rates. As part of our ongoing asset-liability management, we currently use the following strategies to manage our interest rate risk:

•originating multifamily loans and commercial real estate loans that generally have shorter maturities than one-to-four family residential real estate loans and have higher interest rates that generally reset from five to ten years;
•investing in investment grade corporate securities and REMICs; and
•obtaining general financing through lower-cost core deposits, brokered deposits, and longer-term FHLB advances and repurchase agreements.
Shortening the average term of our interest-earning assets by increasing our investments in shorter-term assets, as well as originating loans with variable interest rates, helps to match the maturities and interest rates of our assets and liabilities better, thereby reducing the exposure of our net interest income to changes in market interest rates.
 
Net Portfolio Value Analysis. We compute amounts by which the net present value of our assets and liabilities (net portfolio value or “NPV”) would change in the event market interest rates change over an assumed range of rates. Our simulation model uses a discounted cash flow analysis to measure the interest rate sensitivity of our NPV. Depending on current market interest rates, we estimate the economic value of these assets and liabilities under the assumption that interest rates experience an instantaneous and sustained increase or decrease of 100, 200, 300, or 400 basis points, which is based on the current interest rate environment. A basis point equals one-hundredth of one percent, and 100 basis points equals one percent. An increase in interest rates from 3% to 4% would mean, for example, a 100 basis point increase in the “Change in Interest Rates” column below.
 
Net Interest Income Analysis. In addition to NPV calculations, we analyze our sensitivity to changes in interest rates through our net interest income model. Net interest income is the difference between the interest income we earn on our interest-earning assets, such as loans and securities, and the interest we pay on our interest-bearing liabilities, such as deposits and borrowings. In our model, we estimate what our net interest income would be for a twelve-month period. Depending on current market interest rates we then calculate what the net interest income would be for the same period under the assumption that interest rates experience an instantaneous and sustained increase or decrease of 100, 200, 300, or 400 basis points, which is based on the current interest rate environment.

The following tables set forth, as of March 31, 2026, and December 31, 2025, our calculation of the estimated changes in our NPV, NPV ratio, and percent change in net interest income that would result from the designated instantaneous and sustained changes in interest rates (dollars in thousands). Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including relative levels of market interest rates, loan prepayments and deposit repricing characteristics, including decay rates, and correlations to movements in interest rates, and should not be relied on as indicative of actual results.

At March 31, 2026, in the event of a 400 basis point decrease in interest rates, we would experience a 2.92% increase in estimated net portfolio value, an 8.73% decrease in net interest income in year one, and a 21.44% decrease in net interest income in year two. In the event of a 400 basis point increase in interest rates, we would experience a 19.86% decrease in estimated net portfolio value, a 9.77% decrease in net interest income in year one and a 3.29% increase in net interest income in year two. Our policies provide that, in the event of a 200 basis point decrease or less in interest rates, our net present value ratio should decrease by no more than 300 basis points and 10%, and in the event of a 400 basis point increase or less, our net present value should decrease by no more than 475 basis points and 35%. In the event of a 200 basis point decrease or less, our projected net interest income should decrease by no more than 10% in year one and 20% in year two, and in the event of a 400 basis point increase or less, our projected net interest income should decrease by no more than 39% in year one and 24% in year two. At March 31, 2026, and December 31, 2025, we were in compliance with all Board-approved policies with respect to interest rate risk management.
Certain shortcomings are inherent in the methodologies used in determining interest rate risk through changes in net portfolio value and net interest income. Our model requires us to make certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. We also apply consistent parallel yield curve shifts (in both directions) to determine possible changes in net interest income if the theoretical yield curve shifts occurred gradually. Net interest income analysis also adjusts the asset and liability repricing analysis based on changes in prepayment rates resulting from the parallel yield curve shifts. In addition, the net portfolio value and net interest income information presented assume that the composition of our interest-sensitive assets and liabilities existing at the beginning of a period remains constant over the period being measured and assume that a particular change in interest rates is reflected uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although interest rate risk calculations provide an indication of our interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates on our net portfolio value or net interest income and will differ from actual results.
