RUTHERFORD, NJ, October 29, 2025 — Blue Foundry Bancorp (NASDAQ:BLFY) (the “Company”), the holding company for Blue Foundry Bank (the “Bank”), today reported a net loss of $1.9 million, or $0.10 per diluted common share, for the three months ended September 30, 2025, compared to net loss of $2.0 million, or $0.10 per diluted common share, for the three months ended June 30, 2025, and a net loss of $4.0 million, or $0.19 per diluted common share, for the three months ended September 30, 2024.

James D. Nesci, President and Chief Executive Officer, commented, “During the third quarter, we experienced expansion in our net interest margin due to improvements in both yield on assets and cost of funds. Our strategy of focusing on obtaining the full banking relationship, coupled with diversifying our loan portfolio with an emphasis on asset classes that provide higher yields and better risk-adjusted returns, will position us well for continued balance sheet and interest income growth.”

Mr. Nesci further noted, “We remain committed to enhancing shareholder value. This quarter, tangible book value exceeded $15 per share. As our profitability slowly continues to improve, we expect market valuation to follow.”

•Loans increased $41.9 million to $1.71 billion compared to the linked quarter.

•Deposits increased $77.1 million to $1.49 billion compared to the linked quarter. Core deposits increased by $18.6 million compared to the linked quarter.

•Net interest margin increased six basis points to 2.34% compared to the linked quarter.

•Interest income for the quarter was $24.1 million, an increase of $693 thousand, or 3.0%, compared to the linked quarter.

•Interest expense for the quarter was $11.9 million, an increase of $142 thousand compared to the linked quarter.

•Provision for credit losses of $589 thousand was primarily due to the increase in the provision for loans.

•Book value per share and tangible book value per share were $15.14, respectively. See the “Supplemental Information - Non-GAAP Financial Measures” tables below for additional information regarding our non-GAAP measures.

•837,388 shares were repurchased during the quarter at a weighted average share price of $9.09 per share. 500,000 of the shares repurchased were part of a private transaction executed at a slight discount to the market prices at the time.

During the first nine months of 2025, loans increased by $131.4 million. The Company continues to focus on diversifying its lending portfolio. During the first nine months of 2025, we purchased unsecured consumer loans with credit reserves, which is cash collateral held at the Bank. Management has determined the collateral to be sufficient to cover any expected losses in the loan pools. These loans have helped improve yields while having lower exposure to credit loss. As a result of the purchases, the consumer loan portfolio increased by $114.5 million during the first nine months of 2025. In addition, the commercial real estate portfolio increased by $57.4 million, of which $46.3 million was in owner-occupied properties, and the commercial and industrial portfolio increased $8.0 million. The construction and multifamily portfolios decreased by $25.0 million and $23.8 million, respectively, during the nine months ended September 30, 2025.

The details of the loan portfolio are below:

At September 30, 2025, deposits totaled $1.49 billion, an increase of $150.1 million, or 11.17%, from December 31, 2024. This change was driven by increases of $87.5 million in NOW and demand accounts and $81.9 million in time deposits, partially offset by a decrease in savings accounts of $18.3 million. The Company’s strategy is to focus on attracting the full banking relationship of small- to medium-sized businesses through an extensive suite of deposit products. Despite strong competition for deposits in the northern New Jersey market, during the nine months ended September 30, 2025, we were able to increase core customer deposits by $68.2 million, or 10.7%, with commercial deposits increasing $36.1 million during the year-to-date period. In addition, brokered deposits increased $120.0 million during the nine months ended September 30, 2025, as higher cost customer time deposits matured and were supplemented with brokered deposits. Uninsured deposits to third-party customers totaled approximately 13% of total deposits as of September 30, 2025.

The details of deposits are below:

•Net interest income was $12.2 million for the third quarter of 2025 compared to $11.6 million for the second quarter of 2025 as interest income increased $693 thousand, partially offset by an increase in interest expense of $142 thousand.

•Net interest margin increased by six basis points to 2.34%.

•The yield on average interest-earning assets increased nine basis points to 4.67%, while the cost of average interest-bearing liabilities decreased four basis points to 2.72%.

•Average interest-earning assets increased by $21.1 million and average interest-bearing liabilities increased by $23.0 million.

•Non-interest expense increased $347 thousand primarily driven by increases of $206 thousand and $198 thousand in compensation and benefits and professional services, respectively. Compensation and benefits increased primarily due to increased compensation cost and an additional day of expense during the third quarter.

•The Company did not record a tax benefit for the losses incurred during the third quarter of 2025 or the second quarter of 2025 due to the full valuation allowance required on its deferred tax assets.

•The Company’s current tax position reflects the previously established full valuation allowance on its deferred tax assets. At September 30, 2025, the valuation allowance on deferred tax assets was $25.3 million.

•Net interest income was $12.2 million for the third quarter of 2025 compared to $9.1 million for the same period in 2024. The increase was largely due to increases in interest earned on loans and lower interest costs on time deposits.

•Non-interest expense was $13.9 million and $13.3 million for the third quarter of 2025 and 2024, respectively, an increase of $619 thousand.

•Average loans increased by $92.9 million and average interest-bearing deposits increased by $110.3 million.

•Average borrowings decreased by $14.5 million.

•Non-interest expense was $41.1 million, an increase of $1.3 million.

•Compensation and benefits expense increased by $1.2 million, primarily driven by increases in variable compensation accruals. Additionally, data processing expense, advertising, and professional services increased by $294 thousand, $133 thousand and $103 thousand, respectively.

•Cash and cash equivalents increased $1.6 million to $44.1 million.

•Securities available-for-sale decreased $23.1 million to $273.9 million due to maturities, calls and pay downs, partially offset by purchases and a decrease in the unrealized loss position of $8.6 million.

•Securities held-to-maturity decreased $6.0 million due to pay downs in the portfolio.

•Total loans held for investment increased $131.4 million to $1.71 billion.

•Consumer, commercial real estate and commercial and industrial loans increased $114.5 million, $57.4 million, and $8.0 million, respectively. Partially offsetting these increases was a decrease in construction loans and multifamily loans of $25.0 million and $23.8 million, respectively.

•During the nine months ended September 30, 2025, the Company purchased consumer and residential loans totaling $123.8 million and $35.3 million, respectively.

•Deposits totaled $1.49 billion at September 30, 2025, increasing $150.1 million from $1.34 billion at December 31, 2024. This increase was driven by a $87.5 million increase in NOW and demand accounts and a $81.9 million increase in certificates of deposits, partially offset by a decrease of $18.3 million in savings accounts.

•Core deposits (defined as non-interest bearing checking, NOW and demand accounts and savings accounts) increased $68.2 million and represented 57.8% of total deposits, excluding brokered deposits, at September 30, 2025, compared to 53.5% at December 31, 2024.

•Brokered deposits totaled $275.0 million and $155.0 million at September 30, 2025 and December 31, 2024, respectively. The increase in brokered deposits offset the reduction in retail time deposits and helped fund loan growth.

•Uninsured and uncollateralized deposits to third-party customers were $194.1 million, or 13% of total deposits, at the end of the third quarter.

•At September 30, 2025, FHLB borrowings totaled $301.0 million, a decrease of $38.5 million from December 31, 2024.

•As of September 30, 2025, the Company had $283.8 million of additional borrowing capacity at the FHLB, $109.4 million in secured lines at the Federal Reserve Bank and $30.0 million of other unsecured lines of credit.

•Shareholders’ equity was $314.4 million at September 30, 2025, a decrease of $17.8 million from December 31, 2024. The decrease was primarily driven by the repurchase of shares, including shares netted for income tax withholding on vested equity awards, at a cost of $16.3 million. Additionally, the year-to-date loss, partially offset by favorable changes in accumulated other comprehensive income, contributed to the decrease in shareholders’ equity.

•Tangible equity to tangible assets was 14.58% and tangible common equity per share outstanding was $15.14. See the “Supplemental Information - Non-GAAP Financial Measures” tables below for additional information regarding our non-GAAP measures.

•The Bank’s capital ratios remain above the FDIC’s “well capitalized” standards.

•The allowance for credit losses (“ACL”) on loans as a percentage of gross loans was 0.81% as of September 30, 2025.

•The Company recorded a provision for credit losses of $589 thousand for the third quarter of 2025, primarily driven by deterioration in the economic variable forecasts. For the third quarter of 2025, the provision for the ACL on loans, off-balance-sheet commitments and held-to-maturity securities was $555 thousand, $24 thousand and $10 thousand, respectively. The provision for credit losses for the nine months ended September 30, 2025 was $1.3 million. The provision for the ACL on loans, off-balance-sheet commitments and held-to-maturity securities totaled $905 thousand, $346 thousand and $2 thousand, respectively.

•Non-performing loans totaled $11.4 million, or 0.66% of total loans compared to $5.1 million, or 0.33% of total loans at December 31, 2024. The increase in non-performing loans was primarily driven by one commercial credit for $5.3 million that has previously been disclosed as a special mention asset. Legal proceedings have commenced and we are seeking the appointment of a rent receiver. At this time, we do not believe any principal is at risk.

•Net charge-offs for the three and nine months ended September 30, 2025 were $25 thousand and $36 thousand, respectively.

•The ratio of allowance for credit losses on loans to non-performing loans was 121.49% at September 30, 2025 compared to 254.02% at December 31, 2024, as a result of the increase in non-performing loans as noted above.

Supplemental Information - Non-GAAP Financial Measures

(Unaudited)

This press release contains certain supplemental financial information, described in the table below, which has been determined by methods other than U.S. Generally Accepted Accounting Principles ("GAAP") that management uses in its analysis of Blue Foundry's performance. Management believes these non-GAAP financial measures provide information useful to investors in understanding Blue Foundry's financial results. These non-GAAP measures should not be considered a substitute for GAAP basis measures and results and Blue Foundry strongly encourages investors to review its consolidated financial statements in their entirety and not to rely on any single financial measure. 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.

Net income, as presented in the Consolidated Statements of Operations, includes the provision for credit losses and income tax expense, while pre-provision net revenue does not.
