• Interest income increased during the current quarter, primarily attributable to an increase in the average balance of and weighted average rate on loans as a result of the continued execution of our growth strategy, partially offset by a reduction in the average balance of and weighted average rate on short-term investments.
• Interest expense increased for the current quarter, primarily driven by increases in the average balances of certificates of deposit and individual retirement accounts and FHLB borrowings, partially offset by a decrease in the weighted average rate on certificates of deposit and individual retirement accounts.

Provision for credit losses decreased $3.1 million, or 49.5%, to a provision for credit losses of $3.2 million for the current quarter, compared to a provision for credit losses of $6.3 million for the prior quarter.

• The provision for credit losses on loans decreased $3.4 million, or 53.1%, to $3.0 million for the current quarter, compared to $6.4 million for the prior quarter, primarily driven by an $822 thousand recovery from a commercial and industrial loan, improved qualitative factors on commercial real estate and multi-family loans and no downgrades in qualitative factors, which existed in the prior quarter.

NONINTEREST INCOME
Noninterest income increased $1.0 million, or 23.2%, to $5.6 million for the current quarter, compared to $4.5 million for the prior quarter.

• Customer service fees increased $550 thousand, or 17.6%, to $3.7 million for the current quarter, compared to $3.1 million in the prior quarter due to increased loan fee income, cash management fees and customer transactional volume.

• Marketing and charitable contribution expenses increased $497 thousand, or 48.1%, to $1.5 million for the current quarter, compared to $1.0 million for the prior quarter, primarily resulting from advertising expenses related to customer events and branch openings, as well as a higher volume of Bank contributions to charities during the current quarter.
• Data processing expenses increased $460 thousand, or 10.4%, to $4.9 million for the current quarter, compared to $4.4 million for the prior quarter, primarily driven by our continued investment in technology and systems in support of upcoming revenue initiatives, requiring the operation of systems in parallel for a period of time while new systems are implemented.
• FDIC and state insurance assessment expenses increased $432 thousand, or 37.5%, to $1.6 million for the current quarter, compared to $1.2 million for the prior quarter, primarily driven by increased insurance assessments related to the BankProv acquisition.

INCOME TAXES
Income tax expense increased $1.0 million, or 18.7%, to $6.4 million for the current quarter, compared to $5.4 million for the prior quarter. The increase was primarily driven by the increase in net income during the current quarter. The effective tax rate and the operating effective tax rate⁽¹⁾ were 23.2% and 23.1%, respectively, for the current quarter, compared to 26.4% and 26.2%, respectively, for the prior quarter. The primary drivers of the decrease in the effective tax rate were a higher volume of earned income tax credits and tax-exempt interest income on loans due to the origination of a tax-exempt loan at the end of the prior quarter.

COMMERCIAL REAL ESTATE PORTFOLIO
Commercial real estate loans increased $226.2 million, or 9.2%, to $2.69 billion, during the current quarter.

• Cannabis facility commercial real estate loans decreased $3.7 million, or 1.7%, to $210.1 million during the current quarter. The Company’s cannabis facility commercial real estate portfolio is secured entirely by the underlying commercial real estate of the borrower operation, in addition to, in most cases, a lien on all business assets. The vast majority of the cannabis facility 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 current at the end of the current quarter.
• The Company’s multi-family real estate loan portfolio increased $29.6 million, or 5.5%, during the current quarter to $567.7 million. The Company’s multi-family real estate loan portfolio consists of properties primarily located in the Greater Boston area, all of which are adjustable-rate loans and performing at the end of the current quarter.
• The Company’s $335.7 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 and are performing at the end of the current quarter.

ASSET QUALITY

• The allowance for credit losses (“ACL”) amounted to $82.1 million as of June 30, 2026, or 1.28% of total loans, compared to $80.2 million, or 1.29% of total loans as of March 31, 2026.
• The Company recorded a provision for credit losses of $3.2 million during the current quarter, which included a provision for credit losses on loans of $3.0 million and a provision of $199 thousand for unfunded commitments, compared to a provision for credit losses of $6.3 million during the prior quarter, which included a provision for credit losses on loans of $6.4 million and a release of provision of $54 thousand for unfunded commitments.
• The increase in the ACL for the current quarter was primarily driven by loan growth.
• Non-performing loans (“NPLs”) decreased $17.9 million, or 39.3%, to $27.7 million as of June 30, 2026, from $45.6 million at the end of the prior quarter. The decrease was primarily due to the decrease in commercial and industrial loans on non-accrual of $18.4 million, resulting from improved performance or workouts. The ACL as a percent of NPLs is 297% as of June 30, 2026, an increase from 176% at the end of the prior quarter.
• During the current quarter, the Company recorded total net charge-offs of $1.1 million, or 0.07% of average total loans on an annualized basis, which related to non-purchase-credit-deteriorated (“PCD”) loans, compared to net charge-offs of $13.6 million, or 0.91% of average total loans on an annualized basis, in the prior quarter. The $12.4 million decrease in net charge-offs during the current quarter was primarily a result of prior quarter charge-offs on previously fully reserved for PCD commercial and industrial loans. 
• As part of its ongoing credit risk management framework and prudent oversight, the Company periodically reviews lending relationships across all portfolios to ensure alignment with its risk appetite, regulatory expectations, and evolving market conditions.
• 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, mortgage warehouse 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 greater New England.
