Needham, MA, July 23, 2025 – NB Bancorp, Inc. (the “Company”) (Nasdaq Capital Market: NBBK), the holding company of Needham Bank (the “Bank”), today announced its second quarter 2025 financial results. The Company reported net income of $14.6 million, or $0.39 per diluted common share, compared to net income of $12.7 million, or $0.33 per diluted common share, for the prior quarter. Operating net income, excluding one-time charges, amounted to $15.0 million, or $0.40 per diluted common share, compared to operating net income of $13.7 million, or $0.35 per diluted common share for the prior quarter. The primary difference between net income and operating net income for the second quarter of 2025 was merger and acquisition costs of $530 thousand related to the Company’s pending acquisition of Provident Bancorp, Inc. (“Provident”) and its subsidiary, BankProv, which was announced on June 5, 2025.

“Our second quarter was an exciting period for our entire team as we delivered record earnings, commenced our second share repurchase program and announced our pending acquisition of Provident. We are focused on continued execution of our growth strategy and anticipate closing and converting the acquisition in the fourth quarter of 2025. We were able to continue growing loans during the second quarter, which grew at an annualized rate of 6.8%. However, core deposits remained relatively flat as we prepared for the recent conversion to Q2, an advanced cash management and treasury services platform for commercial customers. Additionally, net interest margin expanded by 21 basis points to 3.82% for the second quarter from 3.61% in the first quarter. We also repurchased over 1.1 million shares in our outstanding share repurchase program with an average per share price of $17.08, providing accretive value to our shareholders. We look forward to the second half of 2025, which we expect will provide the Company with additional growth opportunities on both sides of the balance sheet,” commented Joseph Campanelli, Chairman, President and Chief Executive Officer. “We look forward to continuing to grow market share and taking advantage of opportunities that arise while we prudently manage shareholders’ equity and enhance shareholder value,” Campanelli continued.

Declaration of Dividend

The Board of Directors declared a quarterly cash dividend of $0.07 per share, payable on August 20, 2025, to shareholders of record as of August 6, 2025.

SELECTED FINANCIAL HIGHLIGHTS FOR THE SECOND QUARTER OF 2025

●

Net income of $14.6 million, or $0.39 per diluted common share, compared to net income of $12.7 million, or $0.33 per diluted common share, for the prior quarter. Operating net income, excluding one-time charges, amounted to $15.0 million, or $0.40 per diluted common share, compared to operating net income of $13.7 million, or $0.35 per diluted common share for the prior quarter.

One-time charges during the current quarter include:

o

Merger and acquisition costs of $530 thousand related to the Company’s pending acquisition of Provident;

o

Income tax expense and a modified endowment contract penalty related to the surrender of bank-owned life insurance (“BOLI”) policies of $64 thousand.

●	Net interest margin expanded 21 basis points to 3.82% during the current quarter from 3.61% in the prior quarter.

●	Gross loans increased $76.7 million, or 1.7%, to $4.54 billion, from $4.46 billion the prior quarter.

●	Total deposits decreased $58.6 million, or 1.4%, from the prior quarter. Core deposits, which the Company considers to be all non-brokered deposits, decreased $3.5 million, or 0.1%, during the current quarter. Brokered deposits decreased $55.1 million, or 17.8%, from the prior quarter.

●

Book value per share and tangible book value per share were $18.09 and $18.06, respectively, which decreased from $18.23 and $18.20, respectively in the prior quarter. The decrease in tangible book value per share was a result of the issuance of 1,284,525 shares from restricted stock awards granted during the quarter partially offset by the repurchase of 1,106,588 shares during the current quarter at an all-in weighted average cost of $17.08 per share and $14.6 million in net income for the quarter.

BALANCE SHEET

Total assets amounted to $5.23 billion as of June 30, 2025, representing a decrease of $15.6 million, or 0.3%, from March 31, 2025.

●

Cash and cash equivalents decreased $54.7 million, or 17.5%, to $258.7 million from $313.4 million in the prior quarter, as a result of the increase in loans of $76.7 million, the decrease in deposits of $58.6 million and the repurchase of 1,106,588 million shares during the quarter, partially offset by cash proceeds received for the surrender of BOLI policies of $48.8 million and an increase in FHLB borrowings of $36.8 million.

●

Net loans increased $72.4 million, or 1.6%, to $4.50 billion, from the prior quarter as demand for new loan originations and advances continued. The current quarter growth was primarily seen in construction and land development loans, which increased $77.9 million, or 12.1%, and commercial and industrial loans, which increased $15.7 million, or 2.6%, and residential real estate loans, which increased $8.8 million, or 0.7%; partially offset by a decrease in multi-family residential loans of $24.9 million, or 7.3%.

●	Deposits decreased $58.6 million, or 1.4%, to $4.27 billion from $4.33 billion in the prior quarter. The decrease in deposits was the result of reductions in brokered deposits of $55.1 million, or 17.8%, resulting from maturities during the quarter and utilization of FHLB borrowings.

●	FHLB borrowings increased $36.8 million, or 40.5%, to $127.6 million from $90.8 million during the current quarter as a result of increased borrowings due to loan growth and brokered deposit maturities.

●

Shareholders’ equity decreased $2.5 million, or 0.3%, to $737.1 million from the prior quarter, primarily as a result of $18.9 million related to the repurchase of 1,106,588 shares of common stock at an all-in weighted average cost of $17.08 per share, partially offset by $14.6 million in net income. Shareholders’ equity to total assets and tangible shareholders’ equity to tangible assets were 14.1% at the end of both the current and prior quarter.

NET INTEREST INCOME

Net interest income was $47.0 million for the quarter ended June 30, 2025, compared to $43.5 million for the prior quarter, an increase of $3.5 million, or 8.0%. Net interest margin expanded 21 basis points to 3.82% for the quarter from 3.61% in the prior quarter.

●

The increase in interest income during the quarter ended June 30, 2025 was primarily attributable to an increase in the average balance of loans, default interest earned on loan workouts and increased yield on other investments due to the semi-annual FRB stock dividend, partially offset by a decrease in the average balance of short-term investments.

●	The decrease in interest expense for the quarter ended June 30, 2025 was primarily driven by decreases in the average rate on certificates of deposit and individual retirement accounts.

PROVISION FOR CREDIT LOSSES

Provision for credit losses increased $2.0 million, or 173.0%, to $3.2 million for the quarter ended June 30, 2025, compared to $1.2 million for the prior quarter.

●

The provision for credit losses on loans was $4.2 million for the quarter ended June 30, 2025, compared to $947 thousand for the prior quarter, representing an increase of $3.3 million, or 348.2%, primarily driven by expansion of weighted average remaining maturities periods on construction and land development loans, as well as an increased utilization of national historical loss rates on our commercial portfolios, coupled with an overall increase in the Company’s loan portfolio.

●

The provision for credit losses on unfunded commitments was a release of $1.1 million for the quarter ended June 30, 2025, compared to a provision of $211 thousand for the prior quarter, representing a decrease of $1.3 million, or 613.3%. primarily driven by a reduction in the balance of unfunded commitments during the current quarter.

NONINTEREST INCOME

Noninterest income was $4.2 million for the quarter ended June 30, 2025, compared to $3.9 million for the prior quarter, representing an increase of $317 thousand, or 8.2%.

●	Swap contract income was $524 thousand, compared to $88 thousand in the prior quarter, representing an increase of $436 thousand, or 495.5%, due to increased swap contract demand.

●	Other income was $172 thousand, compared to $8 thousand in the prior quarter, resulting in an increase of $164 thousand, or 2,050.0% due to an annual MasterCard branding bonus earned during the current quarter.

●	The above increases were partially offset by a decline in the cash surrender value of BOLI of $244 thousand, or 23.7%, which was $787 thousand, compared to $1.0 million in the prior quarter, due to proceeds received from the surrender of BOLI policies.

NONINTEREST EXPENSE

Noninterest expense for the quarter ended June 30, 2025 was $29.3 million, representing an increase of $645 thousand, or 2.3%, from the prior quarter.

●

Director and professional service fees increased $795 thousand, or 37.0%, to $2.9 million in the current quarter, compared to $2.1 million in the prior quarter, primarily a result of $527 thousand in stock compensation expense from restricted stock awards granted during the current quarter, along with an increase of $175 thousand in professional services and a $105 thousand increase in legal expenses.

●	Merger and acquisition expenses increased from $0 to $530 thousand, driven by expenses incurred from merger and acquisition costs related to the Provident acquisition.

●

The above increases were partially offset by a $582 thousand decrease in salaries and benefits expenses during the current quarter, primarily resulting from: a $1.2 million decrease in pension expense as the plan was liquidated during the prior quarter, and a $509 thousand decrease in employer tax expenses as a result of the bonus payout and the rate reset during the prior quarter; partially offset by a $609 thousand increase in employee salaries expense resulting from increased headcount, a $261 thousand increase in stock compensation expense for restricted stock awards granted during the current quarter and a $177 thousand increase in the Directors plan expenses.

INCOME TAXES

Income tax expense for the quarter ended June 30, 2025 was $4.1 million, representing a $774 thousand, or 15.8%, decrease from the prior quarter. The decrease was primarily driven by a $6.8 million investment in a solar tax credit investment during the current quarter.

The effective tax rate for the current quarter was 22.1%, compared to 28.0% in the prior quarter. The primary driver of the decrease in the effective tax rate was the significant amount of solar income tax credits earned during the current quarter.

COMMERCIAL REAL ESTATE PORTFOLIO

Commercial real estate loans decreased $27.4 million, or 1.6%, to $1.69 billion, during the quarter ended June 30, 2025.

●	Cannabis facility commercial real estate loans decreased $51.8 million, or 16.1%, during the quarter ended June 30, 2025. The Company’s cannabis facility commercial real estate portfolio is secured entirely by the underlying commercial real estate of the borrower operation.

The vast majority of the loan portfolio balances have a loan-to-value ratio of 65% or lower, with appraisal reports taking a blended approach (using both cannabis and non-cannabis use comparable real estate sales, which we believe are generally more conservative).

●

The cannabis facility portfolio has geographic dispersion, with lower dollar exposure loans remaining local and larger dollar exposure loans generally tied to multi-state operators with a more national footprint. All cannabis facility loan relationships were pass-rated and current at the end of the current quarter. During the second quarter of 2025, the Company sold a cannabis relationship at par plus expenses and fees, which had previously been placed into receivership by the Company related to issues outside of the borrowing entity and solely with a guarantor on the credit. The Company no longer has any exposure to this credit and no losses were incurred.

●

The Company’s multi-family real estate loan portfolio decreased $24.9 million, or 7.3%, during the current quarter to $316.7 million. The Company’s multi-family real estate loan portfolio consists of properties primarily located in the Greater Boston area, primarily all of which are adjustable-rate loans and all of which were performing at June 30, 2025.

●	Mixed-use commercial real estate loans increased $47.8 million, or 36.0%, during the current quarter, resulting from increased customer demand.

●	The Company’s $192.0 million office portfolio consists principally of suburban Class A and B office space used as medical and traditional offices. The portfolio does not consist of high-rise towers located in Boston.

ASSET QUALITY

●

The allowance for credit losses (“ACL”) amounted to $42.6 million as of June 30, 2025, or 0.94% of total loans, compared to $38.3 million, or 0.86% of total loans at March 31, 2025. The Company recorded provisions for credit losses of $3.2 million during the quarter ended June 30, 2025, which included a provision of $4.2 million for loans offset by a release of $1.1 million in the provision for unfunded commitments, compared to provisions for credit losses of $1.2 million during the prior quarter.

●	The increase in the ACL for the quarter ended June 30, 2025 was the result of expansion of weighted average remaining maturities periods on construction and land development loans, as well as a higher use of national loss rates as peer proxies on our commercial portfolios.

●

Non-performing loans totaled $12.5 million as of June 30, 2025, an increase of $1.1 million, or 9.7%, from $11.4 million at the end of the prior quarter. The increase was primarily due to the increase in commercial real estate loans on non-accrual of $1.1 million during the quarter ended June 30, 2025.

●

During the quarter ended June 30, 2025, the Company recorded total net recoveries of $19 thousand, or 0.00% of average total loans on an annualized basis, compared to a $1.4 million net charge off, or 0.12% of average total loans on an annualized basis, in the prior quarter. The decrease in net charge-offs during the quarter ended June 30, 2025 was primarily a result of a $923 thousand recovery on a previously charged-off commercial real estate participation loan.

●

The Company’s loan portfolio consists primarily of commercial real estate and multi-family loans, one-to-four-family residential real estate loans, construction and land development loans, commercial and industrial loans and consumer loans. These loans are primarily made to individuals and businesses located in our primary lending market area, which is the Greater Boston metropolitan area and surrounding communities in Massachusetts, eastern Connecticut, southern New Hampshire and Rhode Island.
