•Completion of Core Conversion: The Company successfully completed its core system conversion and integration activities in September, positioning the Company to realize anticipated cost savings beginning in the fourth quarter of 2026.

•Capital Outlook: With the completion of the core conversion and substantially all major integration activities, the Company expects to resume excess capital accretion in the fourth quarter of 2026.

Chief Executive Officer, Christopher D. Maher, commented on the Company’s results, “We are pleased with the increases in margin and profitability and the timely and successful completion of the Flushing integration. The integration of Flushing clients into OceanFirst was executed smoothly, allowing us to deliver a unified operating platform under the OceanFirst Bank brand. This achievement has allowed us to eliminate redundant back-office operating expenses, improve operational efficiencies, and launch our first advertising campaigns in the New York market.” Mr. Maher added, “With the integration complete, we are focused on leveraging the scale and capabilities of the combined company to enhance the customer experience and support long-term, profitable growth.”

The Company’s Board of Directors declared its 119th consecutive quarterly cash dividend on common stock. The quarterly cash dividend on common stock of $0.20 per share will be paid on November 20, 2026, to common stockholders and NVCE stockholders of record on November 9, 2026.

Results of Operations

On June 1, 2026, the Company completed its acquisition of Flushing Financial Corporation and its wholly-owned subsidiary Flushing Bank (collectively, “Flushing”), and its results of operations from June 1, 2026 through September 30, 2026 are included in the consolidated results for the three and nine months ended September 30, 2026, but are not included in the results of operations for the corresponding prior year periods. The current quarter included $37.1 million of non-recurring merger-related expenses for the Flushing acquisition, representing $29.4 million net of tax, or $0.30 per share. Additionally, the current quarter included $5.5 million of non-recurring interest income related to payoffs of a non-performing investment and loan acquired from Flushing, including $4.0 million and $1.5 million of interest recoveries, respectively.

Net Interest Income and Margin

Three months ended September 30, 2026 vs. September 30, 2025

Net interest income increased to $172.1 million, from $90.7 million, reflecting the net impact of the acquisition of Flushing and the interest rate environment. Net interest margin increased to 3.18%, from 2.91%, which included the impact of purchase accounting accretion and prepayment fees of 0.16% and 0.02%, respectively, and the impact of purchase accounting on average interest-earning assets.

Average interest-earning assets increased by $9.13 billion, which was impacted by assets acquired from Flushing combined with increases in commercial loans and securities. The average yield for interest-earning assets increased to 5.57%, from 5.21%, primarily due to the net impact of the Flushing acquisition, including purchase accounting and recovery of interest income, as well as repricing of assets and new originations.

The cost of average interest-bearing liabilities increased to 2.92%, from 2.85%, primarily due to the full quarter impact of higher-cost deposits acquired from Flushing, partially offset by the repricing of deposits and, to a lesser extent, Federal Home Loan Bank (“FHLB”) advances. The total cost of

4

deposits increased 11 basis points to 2.17%, from 2.06%. Average interest-bearing liabilities increased by $7.62 billion, driven by liabilities assumed from Flushing, growth in deposits and increases in FHLB advances.

Nine months ended September 30, 2026 vs. September 30, 2025

Net interest income increased to $389.3 million, from $264.9 million, reflecting the acquisition of Flushing and the net impact of the interest rate environment. Net interest margin increased to 3.07%, from 2.91%, which included the impact of purchase accounting accretion and prepayment fees of 0.09% and 0.03%, respectively.

Average interest-earning assets increased by $4.76 billion, driven by assets acquired from Flushing and increases in commercial loans and, to a lesser extent, securities. The average yield for interest-earning assets increased to 5.36%, from 5.16%, primarily due to the repricing of assets and new originations, and the addition of loans acquired from Flushing at higher yields.

The cost of average interest-bearing liabilities was 2.80% for both periods, primarily due to the full quarter impact of deposits acquired from Flushing at higher rates, offset by the net impact of repricing of deposits and FHLB advances. The total cost of deposits increased two basis points to 2.08%, from 2.06%. Average interest-bearing liabilities increased by $4.04 billion, driven by the acquisition of Flushing, with the remaining increases reflecting deposit growth and increased FHLB advances.

Three months ended September 30, 2026 vs. June 30, 2026

Net interest income increased by $51.4 million, to $172.1 million from $120.7 million, and net interest margin increased to 3.18%, from 3.05%. Net interest margin included the impact of purchase accounting accretion and prepayment fees of 0.16% and 0.05%, respectively.

Average interest-earning assets increased by $5.62 billion, and the yield on average interest-earning assets increased to 5.57%, from 5.29%. As discussed above, the current quarter was impacted by the drivers noted in the year-over-year discussion.

5

The cost of average interest-bearing liabilities increased to 2.92%, from 2.74%. The total cost of deposits increased to 2.17%, from 2.06%. Average interest-bearing liabilities increased by $4.60 billion, driven by the inclusion of Flushing balances for the full quarter, and an increase in FHLB advances.

Provision for Credit Losses

Provision for credit losses for the three and nine months ended September 30, 2026 was $4.3 million and $11.0 million, as compared to $4.1 million and $12.5 million for the corresponding prior year periods, and $4.0 million in the linked quarter. The current quarter provision reflected continuing stable asset quality.

Net loan charge-offs were $1.5 million and $3.7 million for the three and nine months ended September 30, 2026, as compared to $617,000 and $3.5 million for the corresponding prior year periods and $1.5 million for the linked quarter. Annualized net loan charge-offs to average total loans were 0.04% for both the three and nine months ended September 30, 2026, as compared to 0.02% and 0.05% for the corresponding prior year periods and 0.05% for the linked quarter.

Non-interest Income

Three months ended September 30, 2026 vs. September 30, 2025

Other income increased to $13.0 million, as compared to $12.3 million. The increase in other income of $715,000 was driven by an increase in income from bank owned life insurance of $2.5 million, partly offset by decreases in commercial loan swap income of $796,000. Additionally, net gain on sale of loans decreased by $683,000 due to the discontinuation of residential loan originations, including the disposition of the title business at the beginning of the fourth quarter last year.

Nine months ended September 30, 2026 vs. September 30, 2025

Other income decreased to $30.4 million, as compared to $35.3 million. Other income included $711,000 of net losses on equity investments in the current period. The prior period other income

6

included $686,000 of net gains on equity investments. Excluding the impact of these non-core operations, other income decreased by $3.5 million.

The primary drivers were decreases in fees and service charges of $3.4 million and net gain on sale of loans of $2.7 million, both due to the same discontinuation drivers noted above, partly offset by an increase in income from bank owned life insurance of $3.2 million. In addition, the prior period included non-recurring other income of $1.9 million.

Three months ended September 30, 2026 vs. June 30, 2026

Other income in the linked quarter was $10.6 million and included non-core operations of $347,000 related to net losses on equity investments. Excluding non-core operations, other income increased by $2.1 million. The primary drivers were increases in income from bank owned life insurance of $2.0 million and fees and service charges of $1.9 million, primarily due to a full quarter of Flushing activity. This was partly offset by decreases in net gain on other real estate operations of $1.5 million and commercial loan swap income of $747,000.

Non-interest Expense

Three months ended September 30, 2026 vs. September 30, 2025

Operating expenses increased to $151.4 million, as compared to $76.3 million. Operating expenses in the current quarter were impacted by non-core operations of $37.0 million, primarily due to merger-related expenses. Operating expenses in the prior year were impacted by non-core operations of $3.9 million, related to restructuring charges partly offset by a reversal of FDIC special assessment fees. Excluding the impact of non-core operations, operating expenses increased by $41.9 million.

The primary drivers were increases in compensation and benefits of $19.9 million, amortization of intangibles of $5.2 million, data processing of $5.1 million, occupancy expense of $4.9 million and other operating expenses of $3.8 million, which all increased primarily due to the acquisition of Flushing.

7

Nine months ended September 30, 2026 vs. September 30, 2025

Operating expenses increased to $354.6 million, as compared to $212.1 million. Operating expenses in the current year were impacted by non-core operations of $84.0 million, primarily due to merger-related expenses. Operating expenses in the prior year were impacted by non-core operations of $3.9 million, related to restructuring charges partly offset by a reversal of FDIC special assessment fees. Excluding the impact of non-core operations, operating expenses increased by $62.5 million.

The primary drivers were increases in compensation and benefits of $32.6 million, occupancy expense of $7.1 million, amortization of intangibles of $6.8 million, data processing of $6.4 million and other operating expenses of $4.9 million, which all increased primarily due to the acquisition of Flushing.

Three months ended September 30, 2026 vs. June 30, 2026

Operating expenses in the linked quarter were $129.9 million and included non-core operations of $42.7 million, primarily related to merger-related expenses. Excluding non-core operations, operating expenses increased by $27.2 million, which was primarily due to a full quarter of Flushing activity. The primary drivers were increases in compensation and benefits of $11.1 million, data processing of $4.6 million, occupancy expense of $3.6 million, amortization of intangibles of $3.5 million, and other operating expense of $3.0 million.

Income Tax Expense

The provision for income taxes was $13.0 million and $20.1 million for the three and nine months ended September 30, 2026, as compared to $5.2 million and $17.7 million for the same prior year periods and $496,000 for the linked quarter. The effective tax rate was 44.2% and 37.2% for the three and nine months ended September 30, 2026, as compared to 22.9% and 23.4% for the same prior year periods and (19.6)% for the linked quarter.

The effective tax rate for the three and nine months ended September 30, 2026 was adversely impacted by non-deductible merger-related expenses, and the effective tax rate for the nine month

8

period was partially offset by the revaluation of deferred taxes as a result of the Flushing acquisition. Excluding the tax impact of non-deductible merger-related expenses, the effective tax rate would have been 26.6% and 29.5% for the three and nine months ended September 30, 2026, respectively.

Financial Condition3

September 30, 2026 vs. June 30, 2026

Total assets increased by $100.4 million to $23.37 billion, primarily due to increases in total loans of $215.7 million, debt securities held-to-maturity of $134.3 million and other assets of $60.9 million, partially offset by a decrease in debt securities available-for-sale of $296.7 million.

Total liabilities increased by $115.6 million to $20.97 billion, primarily due to increases in deposits of $319.3 million and FHLB advances of $42.6 million, partially offset by a decrease in other liabilities of $197.5 million, mainly reflecting the settlement of security purchases that were outstanding at the end of the prior quarter.

Total stockholders’ equity decreased by $15.1 million, primarily due to an increase in accumulated other comprehensive loss of $14.4 million, net of tax, driven by decreases in the fair market value of available-for-sale debt securities of $25.4 million partially offset by increases in the market value of derivative hedges of $10.5 million.

September 30, 2026 vs. December 31, 2025

Total assets increased by $8.81 billion to $23.37 billion, due to the acquisition of Flushing which added $8.69 billion to total assets. Total loans increased by $5.46 billion to $16.49 billion, from $11.03 billion, primarily due to Flushing totaling $6.20 billion partly offset by $1.31 billion of multifamily loans sold in the prior quarter for a price of $1.20 billion, net of costs to sell. Debt securities held-to-maturity and available-for-sale increased by $2.65 billion, primarily due to the acquisition of Flushing totaling $1.56 billion and the reinvestment of proceeds from loan sales into securities. Bank owned life insurance increased by $237.1 million to $507.4 million, from $270.3

3 Flushing amounts refer to estimated fair values as of the June 1, 2026 acquisition date, unless otherwise noted.

million driven by the acquisition of Flushing. As part of the acquisition of Flushing, the Company’s goodwill balance increased to $530.8 million, from $517.5 million and intangibles increased to $84.5 million, from $9.0 million.

Other assets increased by $278.5 million to $427.8 million, from $149.3 million, primarily due to deferred tax assets acquired from the Flushing acquisition and an increase in market values of derivatives associated with customer interest rate swaps.

Total liabilities increased by $8.07 billion to $20.97 billion, from $12.90 billion, primarily due to the acquisition of Flushing, which added $8.16 billion. Deposits increased by $7.11 billion to $18.08 billion, from $10.96 billion, primarily due to acquired deposits from Flushing. At the date of acquisition, the estimated fair value of Flushing deposits was $7.44 billion. Time deposits increased by $1.88 billion to $4.35 billion, from $2.47 billion, representing 24.1% and 22.5% of total deposits, respectively. Time deposits included an increase in retail time deposits of $1.44 billion and brokered time deposits of $439.6 million. FHLB advances increased by $377.8 million to $1.77 billion, from $1.40 billion, partly due to Flushing and additional borrowing needs. Other borrowings increased by $241.3 million to $496.6 million, from $255.2 million, driven by the addition of subordinated debt and trust preferred securities from the acquisition of Flushing. The loan-to-deposit ratio was 91.2%, as compared to 100.6%.

Other liabilities increased by $292.3 million to $501.6 million, from $209.3 million, mostly related to increases in market values of derivatives associated with customer interest rate swaps.

Capital levels remain strong and in excess of “well-capitalized” regulatory levels at September 30, 2026, including the Company’s estimated common equity tier one capital ratio of 10.6%.

Total stockholders’ equity increased to $2.40 billion, as compared to $1.66 billion, primarily due to the acquisition of Flushing, which added $535.6 million to stockholders’ equity. The current period also included a $225 million capital raise consisting of approximately 9.6 million shares of common stock, 1.8 million shares of NVCE stock, and warrants to purchase 11.4 million shares of

10

NVCE stock. Additionally, accumulated other comprehensive loss increased by $15.6 million, net of tax, primarily due to decreases in the fair market value of available-for-sale debt securities of $26.2 million partially offset by increases in the market value of derivative hedges of $9.9 million.

During the nine months ended September 30, 2026, the Company repurchased 415,348 shares of common stock related to exercised options and vesting of employee awards outside of the authorized share repurchase program, at a weighted average cost of $18.76. The repurchases, including applicable excise tax, reduced stockholders’ equity by $7.9 million.

Asset Quality

September 30, 2026 vs. December 31, 2025

The Company’s allowance for loan credit losses was 1.29% of total loans, as compared to 0.76%. The increase in the allowance for credit losses was largely driven by incremental allowance for loan credit losses of $121 million added for the Flushing portfolio on June 1 and the reserve build. Refer to “Provision for Credit Losses” section for further discussion.

Non-performing loans increased to $140.7 million, from $27.8 million, primarily due to $84.6 million of non-performing loans acquired from Flushing. Non-performing loans represented 0.85% and 0.25% of total loans, respectively. The allowance for loan credit losses as a percentage of

total non-performing loans was 150.84%, as compared to 301.27%. The level of 30 to 89 days delinquent loans decreased to $43.1 million, from $47.8 million, which was partially offset by $13.2 million of 30 to 89 days delinquent loans acquired from Flushing. Criticized and classified loans, and other real estate owned, increased to $529.6 million, from $122.1 million, largely due to Flushing loans that were re-risked at acquisition.

At September 30, 2026, the Company had $727.1 million of purchased with credit deterioration (“PCD”) loans, excluding the related allowance, from the Flushing acquisition, which largely consisted of criticized and classified loans and loans with any rent-regulated exposure. Non-performing loans in the current period included $79.3 million of PCD loans acquired from Flushing, and 30 to 89 days delinquent loans in the current period included $7.1 million of PCD loans acquired from Flushing.

The Company’s asset quality measures, excluding PCD loans, were as follows. Non-performing loans increased to $60.9 million, from $22.4 million. The allowance for loan credit losses as a percentage of total non-performing loans was 348.74%, as compared to 374.46%. The level of 30 to 89 days delinquent loans, excluding non-performing loans, decreased to $26.2 million, from $44.7 million.

Explanation of Non-GAAP Financial Measures

Reported amounts are presented in accordance with GAAP. The Company’s management believes that the supplemental non-GAAP information, which consists of reported net income excluding non-core operations and in some instances excluding income taxes and provision for credit losses, and reporting equity and asset amounts excluding intangible assets and goodwill, all of which can vary from period to period, provides a better comparison of period-to-period operating performance. Additionally, the Company believes this information is utilized by regulators and market analysts to evaluate a company’s financial condition and, therefore, such information is useful to investors. These disclosures should not be viewed as a substitute for financial results in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures, which may be presented by other companies. Refer to the Non-GAAP Reconciliation table at the end of this document for details on the earnings impact of these items.
