Key Terms

non-gaap financial measure, available for sale, held to maturity, bargain purchase gain

4 terms

non-gaap financial measure financial

"core net income (a non-GAAP financial measure)"

A non-GAAP financial measure is a way companies present their financial results that excludes certain expenses or income to show how they believe their core business is performing. It matters because it can give a clearer picture of how the company is really doing, but it can also be used to make results look better than they actually are.

available for sale financial

"debt securities designated as both available for sale and held to maturity"

Available for sale describes investments, usually bonds or stocks, that a company intends to keep but may sell before they mature; they are reported at current market value on the balance sheet while any unrealized profit or loss is kept separate from regular earnings. For investors, this matters because changes in market value affect a company’s reported net worth and can become realized gains or losses when sold, similar to how the changing resale value of a collectible affects your net wealth even before you sell it.

held to maturity financial

"debt securities designated as both available for sale and held to maturity"

A "held to maturity" classification applies to debt securities a company intends and is able to keep until they are fully repaid. Think of it like putting a bond in a locked safe until the issuer returns your money; the company does not mark the holding to daily market swings, so reported income and balance-sheet values are steadier. For investors, it signals predictable future interest receipts and reduced volatility in reported results, but also less liquidity if cash is needed before maturity.

bargain purchase gain financial

"recorded a bargain purchase gain of $25.7 million, net of tax"

A bargain purchase gain happens when a buyer acquires another company's assets for less than those assets' estimated fair value, producing an immediate accounting profit for the buyer. For investors, it matters because that one-time gain boosts the acquirer's reported earnings and can signal a very favorable deal — like finding a valuable item at a steep discount — but it may also prompt scrutiny about whether asset values or the deal terms were estimated correctly.

Approximately one-third of these debt securities purchased have coupons that adjust monthly. Furthermore, the Company repaid and prepaid $353.5 million of borrowings with a weighted average cost of 3.97%.
• The sale of $650.6 million of Northfield debt securities available for sale resulting in no gain or loss, as the securities were marked-to-market as part of purchase accounting adjustments.

Results of Operations for the Three Months Ended September 30, 2026 and September 30, 2025

Net income of $5.2 million was recorded for the quarter ended September 30, 2026, a decrease of $9.6 million compared to net income of $14.9 million for the quarter ended September 30, 2025. The decrease in net income was primarily attributable to a $23.8 million decrease in non-interest income and a $52.4 million increase in non-interest expense, partially offset by a $57.0 million increase in net interest income, a $512,000 decrease in provision for credit losses and a $9.1 million decrease in income tax expense.

The increase in net interest income was primarily attributable to a $72.2 million increase in interest income partially offset by a $15.2 million increase in interest expense on deposits and borrowings. The increase in interest income was primarily due to an increase in the average balance of total interest-earning assets coupled with an increase in average yields on loans, while the increase in interest expense was primarily due to an increase in the average balance of both deposits and borrowings. Accretion of loan yield adjustments for the quarter ended September 30, 2026 totaled $6.8 million.

The average yield on loans for the quarter ended September 30, 2026 increased 33 basis points to 5.37%, as compared to 5.04% for the quarter ended September 30, 2025. Interest income on loans increased due to an increase in both the average balance and yield on loans mainly related to the Northfield acquisition. The average yield on securities for the quarter ended September 30, 2026 increased 55 basis points to 3.96%, as compared to 3.41% for the quarter ended September 30, 2025. The average yield on other interest-earning assets for the quarter ended September 30, 2026 decreased 137 basis points to 3.87%, as compared to 5.24% for the quarter ended September 30, 2025, mainly due to an increase in the average balance of other interest-earning assets invested in lower earning interest-bearing cash accounts, coupled with a 91 basis point decrease in the dividend rate received on Federal Home Loan Bank stock.

Total interest expense was $78.3 million for the quarter ended September 30, 2026, an increase of $15.2 million, or 24.2%, from $63.0 million for the quarter ended September 30, 2025. The increase in interest expense was primarily attributable to increases in the average balance of interest-bearing deposits and borrowings partially offset by a 31 basis point decrease in the average cost of interest-bearing deposits coupled with a 17 basis point decrease in the average cost of borrowings. Interest expense on deposits increased $13.3 million, or 26.8%, primarily due to the increase in the average balances as a result of the Northfield acquisition during the quarter ended September 30, 2026. Interest expense on borrowings increased $2.0 million, or 14.7%, for the quarter ended September 30, 2026 as compared to the quarter ended September 30, 2025 due to an increase in the average balance of borrowings, partially offset by a decrease in the average cost of borrowings.

The Company's net interest margin for the quarter ended September 30, 2026 increased 67 basis points to 2.96% when compared to 2.29%, for the quarter ended September 30, 2025, predominately due to a decrease in the average cost of interest-bearing liabilities.

The decrease in the provision for credit losses was primarily attributable to lower net charge-offs, partially offset by an increase in loan balances.

Non-interest (loss) income was $(13.9) million for the quarter ended September 30, 2026, a decrease of $23.8 million, or 241.0%, from $9.9 million for the quarter ended September 30, 2025, mainly due to a $40.8 million increase in the loss on securities transactions coupled with a $7.6 million loss on transfer of loans to held-for-sale as previously discussed. These decreases were partially offset by a bargain purchase gain of $25.7 million, net of tax, related to the Northfield acquisition.

Non-interest expense was $97.5 million for the quarter ended September 30, 2026, an increase of $52.4 million, or 116.3%, from $45.1 million for the quarter ended September 30, 2025. The increase was primarily attributable to an increase in compensation and employee benefits expense of $14.2 million, an increase in occupancy expense of $2.6 million, an increase in merger-related expenses of $30.6 million, and an increase in amortization of intangible assets of $2.9 million due to the Northfield acquisition. The increase in compensation and employee benefits expense was due to an increase in the number of employees and related employee benefits due to the Northfield acquisition and annual merit increases. The increase in occupancy expense was due to the costs related to the Northfield acquisition.

An income tax benefit of $4.1 million was recorded for the quarter ended September 30, 2026, a decrease of $9.1 million, as compared to income tax expense of $5.0 million for the quarter ended September 30, 2025, mainly due to lower pre-tax income partially offset by non-deductible merger-related expenses.

The increase in net interest income was primarily attributable to a $84.7 million increase in interest income partially offset by a $8.4 million increase in interest expense on deposits and borrowings. The increase in interest income was primarily due to an increase in the average balance of loans coupled with an increase in the average yield on loans. Accretion of loan yield adjustments for the nine months ended September 30, 2026 totaled $6.8 million, mainly related to the Northfield acquisition. Prepayment penalties, which are included in interest income on loans, totaled $1.5 million for the nine months ended September 30, 2026, compared to $1.6 million for the nine months ended September 30, 2025.

The average yield on loans for the nine months ended September 30, 2026 increased 20 basis points to 5.16%, as compared to 4.96% for the nine months ended September 30, 2025. Interest income on loans increased due to an increase in both the average balance and yield on loans. The average yield on securities for the nine months ended September 30, 2026 increased 23 basis points to 3.70%, as compared to 3.47% for the nine months ended September 30, 2025. The average yield on other interest-earning assets for the nine months ended September 30, 2026 decreased 126 basis points to 4.13%, as compared to 5.39% for the nine months ended September 30, 2025, mainly due to an increase in the average balance of other interest-earning assets invested in lower earning interest-bearing cash accounts, coupled with a lower dividend rate received on Federal Home Loan Bank stock.

Total interest expense was $196.1 million for the nine months ended September 30, 2026, an increase of $8.4 million, or 4.5%, from $187.7 million for the nine months ended September 30, 2025. The increase in interest expense was primarily attributable to an increase in the average balances of interest-bearing deposits and borrowings, partially offset by a 30 basis point decrease in the average cost of interest-bearing deposits coupled with a 27 basis point decrease in the average cost of borrowings mainly related to the Northfield acquisition. Interest expense on deposits increased $6.2 million, or 4.2%, for the nine months ended September 30, 2026 as compared to the nine months ended September 30, 2025, due to an increase in the average balance of deposits, while interest expense on borrowings increased $2.2 million, or 5.7%, for the nine months ended September 30, 2026 as compared to the nine months ended September 30, 2025, due to the increase in the average balance of borrowings.

The Company's net interest margin for the nine months ended September 30, 2026 increased 46 basis points to 2.66% when compared to 2.20% for the nine months ended September 30, 2025, due to an increase in the average yield on interest-earning assets coupled with a decrease in the average cost of interest-bearing liabilities. The weighted average yield on interest-earning assets increased 10 basis points to 4.85% for the nine months ended September 30, 2026 as compared to 4.75% for the nine months ended September 30, 2025.

The provision for credit losses for the nine months ended September 30, 2026 was $7.1 million, a decrease of $645,000, or 8.3% from $7.7 million for the nine months ended September 30, 2025. The decrease in the provision for credit losses was primarily attributable to a decrease in net charge-offs, which totaled $2.9 million for the nine months ended September 30, 2026 as compared to $5.2 million for the nine months ended September 30, 2025, partially offset by an increase in loan balances.

Non-interest income was $3.7 million for the nine months ended September 30, 2026, a decrease of $24.8 million, or 87.1%, from $28.5 million for the nine months ended September 30, 2025. The decrease was primarily attributable to a $40.8 million increase in the loss on securities transactions, coupled with a $7.7 million increase in the loss on transfer of loans. These decreases were partially offset by a bargain purchase gain of $25.7 million, net of tax, resulting from the Northfield acquisition, a $2.7 million increase in bank-owned life insurance due to income from the acquisition of such policies in the Northfield acquisition, death benefit claims in the 2026 period, and income related to the transition and exchange into higher yielding bank-owned life insurance policies.

Non-interest expense was $194.4 million for the nine months ended September 30, 2026, an increase of $60.6 million, or 45.3%, from $133.8 million for the nine months ended September 30, 2025. The increase was primarily attributable to an increase in compensation and employee benefits expense of $19.8 million, an increase in occupancy expense of $4.0 million, an increase in data processing and software expenses of $2.7 million and an increase in merger-related expenses of $33.3 million, partially offset by a decrease of $2.6 million in professional fees. The increase in compensation and employee benefits expense was due to an increase in the number of employees and related employee benefits due to the Northfield acquisition and annual merit increases. The increase in occupancy expense was due to the costs related to the Northfield branches acquired.

Income tax expense was $7.0 million for the nine months ended September 30, 2026, a decrease of $5.2 million, as compared to income tax expense of $12.3 million for the nine months ended September 30, 2025, mainly due to a decrease in pre-tax income. The Company's effective tax rate was 49.7% and 25.4% for the nine months ended September 30, 2026 and 2025, respectively. The increase in the 2026 effective tax rate was due primarily to non-deductible merger-related expenses.

The increase in total assets was primarily attributable to increases in cash and cash equivalents of $118.0 million, debt securities available for sale of $1.7 billion, debt securities held to maturity of $516.0 million, loans held-for-sale of $211.4 million, loans receivable, net, of $3.4 billion, bank-owned life insurance of $191.8 million and other assets of $157.6 million, mainly due to assets acquired in the Northfield merger.

Cash and cash equivalents increased $118.0 million, or 34.6%, to $458.8 million at September 30, 2026 from $340.8 million at December 31, 2025. The increase was primarily attributable to proceeds raised through the offering and cash and cash equivalents of $95.2 million acquired in the Northfield acquisition.

Debt securities available for sale increased $1.7 billion, or 151.0%, to $2.8 billion at September 30, 2026 from $1.1 billion at December 31, 2025. The increase was primarily attributable to $1.2 billion of securities acquired in the Northfield acquisition, and purchases of $1.7 billion of securities, consisting primarily of U.S. government obligations and mortgage-backed securities which were purchased with proceeds from the second-step conversion offering. These increases were partially offset by sales of securities with an amortized cost of $643.3 million which were acquired in the Northfield acquisition and the sale of an additional $213.9 million of seasoned securities sold as part of a balance sheet repositioning transaction, which resulted in a realized loss of $40.8 million for the quarter ended September 30, 2026. The Company sold predominantly fixed rate, low-yielding debt securities and used the proceeds to repay high costing borrowings acquired from Northfield and purchase higher-yielding debt securities to improve the net interest rate margin in the future. The increase in debt securities available for sale also included a decrease of $33.9 million in the unrealized loss on securities available for sale.

Debt securities held to maturity increased $516.0 million, or 130.2%, to $912.2 million at September 30, 2026 from $396.2 million at December 31, 2025. The increase was attributable to purchases of securities of $542.8 million, consisting primarily of U.S. government obligations and mortgage-backed securities, partially offset by maturities on securities of $14.9 million, and repayments on securities of $13.1 million.

Loans held-for-sale increased to $211.4 million, at September 30, 2026 from zero at December 31, 2025. A portion of the loans held-for-sale acquired in the Northfield acquisition along with $9.1 million of residential real estate loans originated by Columbia Bank were transferred to loans held-for-sale at fair value and were subsequently sold in October 2026.

Loans receivable, net, increased $3.4 billion, or 41.9%, to $11.7 billion at September 30, 2026 from $8.2 billion at December 31, 2025, primarily due to $3.2 billion of loans acquired in the Northfield acquisition excluding loans held-for sale. One-to-four family real estate loans, multifamily loans, commercial real estate loans, construction loans, commercial business loans and home equity loans and advances increased $84.0 million, $2.0 billion, $774.9 million, $33.1 million, $253.3 million, and $193.8 million, respectively. The allowance for credit losses for loans increased $51.4 million to $118.6 million at September 30, 2026 from $67.2 million at December 31, 2025, primarily due to the Northfield acquisition and organic loan growth during the nine months ended September 30, 2026. As part of the merger with Northfield, the Company acquired $3.5 billion in loans, net of purchase accounting adjustments related to interest rates. The allowance for credit losses increased due to the day 1 Northfield CECL adjustment of $47.1 million recorded as part of the Northfield acquisition.

Bank-owned life insurance increased $191.8 million, or 67.7%, to $474.9 million at September 30, 2026 from $283.1 million at December 31, 2025, as the Company acquired $187.1 million of bank-owned life insurance policies in the Northfield acquisition, and $8.7 million of income was recognized from bank-owned life insurance for the nine months ended September 30, 2026.

Other assets increased $157.6 million, or 47.0%, to $493.3 million at September 30, 2026 from $335.7 million at December 31, 2025 primarily due to $134.2 million in other assets acquired as part of the Northfield acquisition, an increase in net pension assets of $27.0 million, and an increase of $16.6 million in swap contracts.

Total liabilities increased $4.5 billion, or 46.0%, to $14.4 billion at September 30, 2026 from $9.9 billion at December 31, 2025. The increase was primarily attributable to an increase in total deposits of $4.1 billion, primarily due to the addition of Northfield deposits, an increase in borrowings of $312.8 million, and an increase in accrued expenses and other liabilities of $87.4 million. The increase in total deposits consisted of increases in non-interest-bearing demand deposits, interest-bearing demand deposits, money market accounts, savings and club accounts, and certificates of deposits of $810.1 million, $1.4 billion, $254.3 million, $767.6 million and $868.5 million respectively. The increase in each category of deposits largely reflected the impact of deposits acquired from Northfield while also reflecting an increase related to the impact of continuing business development and competitive pricing strategies. The increase in accrued expenses and other liabilities included $67.0 million acquired from Northfield, which primarily consisted of lease liabilities, accrued expenses and benefit plan related liabilities, and an increase in collateral pledged for interest rate swaps. The $312.8 million increase in borrowings was driven by borrowings acquired from Northfield which included a net increase in short-term borrowings of $175.0 million, coupled with new long-term borrowings of $161.8 million, and long-term subordinated debentures assumed from Northfield totaling $62.0 million, partially offset by repayments of $82.0 million in maturing long-term borrowings. Included in these borrowings were $646.4 million in borrowings assumed in the Northfield acquisition, of which $195.6 were subsequently prepaid, resulting in a $196,000 loss on extinguishment of debt.

Total stockholders’ equity increased $2.0 billion, or 172.7%, with a balance of $3.2 billion at September 30, 2026 from $1.2 billion and December 31, 2025. The increase in stockholders' equity reflected $1.6 billion in capital stock issued in the Company's second-step conversion coupled with $404.3 million in capital stock issued in conjunction with the acquisition of Northfield. The increase also included net income of $32.8 million, partially offset by dividends declared and paid of $12.9 million.

Asset Quality

The Company's non-performing loans at September 30, 2026 excluding purchased credit deteriorated ("PCD") loans, totaled $36.5 million, or 0.31% of total gross loans, as compared to $38.0 million, or 0.46% of total gross loans, at December 31, 2025. The $1.5 million decrease in non-performing loans was primarily attributable to a decrease in non-performing one-to-four family loans of $5.4 million. This decrease was mainly due to the transfer of $4.9 million of non-performing one-to-four family loans to loans held-for-sale in September 2026, which were sold in October 2026, a decrease in non-performing commercial business loans of $2.8 million, and a decrease in non-performing construction loans of $4.1 million. The decrease in non-performing construction loans was due to one loan of $5.9 million being transferred to other real estate owned in March 2026 and subsequently sold in September 2026. These decreases were partially offset by an increase of $11.6 million in commercial real estate loans, which included a $10.6 million loan on a six-story mixed use building, located in Philadelphia, Pennsylvania, which contains apartments and commercial/storage space designated as non-performing during the 2026 period. Non-performing assets as a percentage of total assets totaled 0.21% at September 30, 2026, as compared to 0.34% at December 31, 2025.

For the quarter ended September 30, 2026, net charge-offs totaled $1.5 million, as compared to net charge-offs of $1.2 million for the quarter ended September 30, 2025. For the nine months ended September 30, 2026, net charge-offs totaled $2.9 million, as compared to net charge-offs of $5.2 million for the nine months ended September 30, 2025. Charge-offs for the nine months ended September 30, 2025 included $3.2 million in charge-offs related to PCD equipment finance loans purchased in May 2025.

The Company's allowance for credit losses on loans was $118.6 million, or 1.02% of total gross loans, at September 30, 2026, compared to $67.2 million, or 0.82% of total gross loans, at December 31, 2025. The increase in the allowance for credit losses for loans was primarily due to the day 1 Northfield CECL adjustment of $47.1 million recorded as part of the Northfield acquisition.

In addition, with respect to the Company’s recently completed acquisition of Northfield Bancorp (“Northfield”), such risks, uncertainties and assumptions, include, among others, the following: (i) the possibility that the anticipated benefits of the proposed transaction, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which the combined company operates; (ii) the possibility that the integration of the two companies may be more difficult, time-consuming or costly than expected; and (iii) the impact of purchase accounting with respect to the proposed transaction, or any change in the assumptions used regarding the assets acquired and liabilities assumed to determine their fair value and credit marks. Forward-looking statements are subject to numerous risks and uncertainties, including but not limited to, those set forth in Item 1A of the Company's Annual Report on Form 10-K and those set forth in the Company's Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all as filed with the Securities and Exchange Commission (the “SEC”), which are available at the SEC’s website, www.sec.gov. Should one or more of these risks materialize or should underlying beliefs or assumptions prove incorrect, the Company's actual results could differ materially from those discussed. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this release. The Company disclaims any obligation to publicly update or revise any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events or other changes, except as required by law.

Non-GAAP Financial Measures

Reported amounts are presented in accordance with U.S. generally accepted accounting principles ("GAAP"). This press release also contains certain supplemental non-GAAP information that the Company’s management uses in its analysis of the Company’s financial results. Specifically, the Company provides measures based on what it believes are its "core" operating results, and relevant performance ratios on a consistent basis and excludes material non-routine items which affect the GAAP reporting of results of operations, and relevant performance ratios. The Company’s management believes that providing this information to analysts and investors allows them to better understand and evaluate the Company’s core financial results for the periods presented. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.

The Company also provides measurements and ratios based on tangible stockholders' equity. These measures are commonly utilized by regulators and market analysts to evaluate a company’s financial condition and, therefore, the Company’s management believes that such information is useful to investors.

A reconciliation of GAAP to non-GAAP financial measures are included at the end of this press release. See "Reconciliation of GAAP to Non-GAAP Financial Measures".
