These forward-looking statements are based on our current beliefs and expectations and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control.

In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements:

• weakening in the United States economy in general and the regional and local economies within the Company’s market area;
• the effects of inflationary pressures, labor market shortages and/or supply chain issues;
• the instability or volatility in financial markets and unfavorable general business conditions, globally, nationally or regionally, whether caused by geopolitical concerns, recent disruptions in the banking industry, or other factors;
• unanticipated loan delinquencies, loss of collateral, decreased service revenues, and other potential negative effects on our business caused by severe weather, pandemics or other external events;
• changes in the interest rate environment that reduce our margins and yields, our mortgage banking revenues, the fair value of financial instruments, or our level of loan originations, or increase the level of defaults, losses and prepayments on loans we have made and make;
• failure to consummate or a delay in consummating the pending acquisition of Provident Bancorp, Inc. and BankProv, including as a result of any failure to obtain the necessary regulatory approvals or to satisfy any of the other conditions to the proposed transaction on a timely basis or at all;
• risks related to the Company’s pending acquisition of Provident Bancorp, Inc. and BankProv and acquisitions generally, including disruptions to current plans and operations; difficulties in customer and employee retention; fees, expenses and charges related to these transactions being significantly higher than anticipated; unforeseen integration issues or impairment of goodwill and/or other intangibles; and the Company’s inability to achieve expected revenues, cost savings, synergies, and other benefits at levels or within the timeframes originally anticipated;
• changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for credit losses on loans;
• the effect of any change in federal government enforcement of federal laws affecting the cannabis industry;
• changes in liquidity, including the size and composition of our deposit portfolio, including the percentage of uninsured deposits in the portfolio;
• our ability to access cost-effective funding;
• fluctuations in real estate values and both residential and commercial real estate market conditions;
• demand for loans and deposits in our market area;
• our ability to implement and change our business strategies;
• competition among depository and other financial institutions;
• adverse changes in the securities or secondary mortgage markets;
• changes in laws or government regulations or policies affecting financial institutions, including changes in regulatory fees, capital requirements and insurance premiums;
• changes in the quality or composition of our loan or investment portfolios;
• technological changes that may be more difficult or expensive than expected;
• the inability of third-party providers to perform as expected;
• a failure or breach of our operational or security systems or infrastructure, including cyberattacks;
• our ability to manage market risk, interest rate risk, credit risk, compliance risk, and operational risk;
• our ability to enter new markets successfully and capitalize on growth opportunities;
• changes in consumer spending, borrowing and savings habits;
• changes in accounting policies and practices, as may be adopted by the bank regulatory agencies, the Financial Accounting Standards Board, the Securities and Exchange Commission or the Public Company Accounting Oversight Board;
• our ability to attract and retain key employees; and
• changes in the financial condition, results of operations or future prospects of issuers of securities that we own.

Because of these and a wide variety of other uncertainties, our actual future results may be materially different from the results indicated by these forward-looking statements.

Critical Accounting Policies

There are no material changes to the critical accounting policies disclosed in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 7, 2025.

Allowance for Credit Losses

The Company estimates the ACL in accordance with the CECL methodology for loans measured at amortized cost. The ACL is established based upon the Company's current estimate of expected lifetime credit losses. Arriving at an appropriate amount of ACL involves a high degree of judgment.

The Company estimates credit losses on a collective basis for loans sharing similar risk characteristics using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. Management's judgement is required for the selection and application of these factors which are derived from historical loss experience as well as assumptions surrounding expected future losses and economic forecasts.

Loans that no longer share similar risk characteristics with any pools of assets are subject to individual assessment and are removed from the collectively assessed pools to avoid double counting.

For the loans that are individually assessed, the Company uses either a discounted cash flow approach or a fair value of collateral approach. The latter approach is used for loans deemed to be collateral dependent or when foreclosure is probable. In limited circumstances, the collateral value for an individually assessed loan may be based on the enterprise value of a company. The enterprise value method involves assessing the borrower’s ability to repay the loan by estimating the total value of its business, including both debt and equity. This approach is typically used where the recoverable value is based on the fair value of the company as a going concern, adjusted for the priority of the Company’s claim. Fair value adjustments are recorded in the period incurred as provision for credit losses in the consolidated statements of income.

Changes in these judgements and assumptions could be due to a number of circumstances which may have a direct impact on the provision for credit losses and may result in changes to the amount of ACL. The ACL is increased by the provision for credit losses and by recoveries of loans previously charged off. Credit losses are charged against the allowance when management's assessments confirm that the Company will not collect the full amortized cost basis of a loan.

Income Taxes

We use the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred tax asset will not be realized. We exercise significant judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets. These judgments may require us to make projections of future taxable income and/or to carryback to taxable income in prior years. The judgments and estimates we make in determining our deferred tax assets and liabilities, which are inherently subjective, are reviewed on a continual basis as regulatory and business factors change. Any reduction in estimated future taxable income may require us to record a valuation allowance against our deferred tax assets.

Securities Valuation

We classify our debt securities as available-for-sale, which are carried at fair value. We obtain our fair values from one or more third-party services. These services’ fair value calculations are based on quoted market prices when such prices are available.

If quoted market prices are not available, estimates of fair value are computed using a variety of techniques, including extrapolation from the quoted prices of similar instruments or recent trades for thinly traded securities, fundamental analysis, or through obtaining purchase quotes. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these investments could differ from the estimated amounts, thereby affecting our financial position, results of operations and cash flows.

For any available-for-sale debt security with a fair value less than its amortized cost basis, we will determine whether we have the intent to sell the available-for-sale debt security or whether it is more likely than not we will be required to sell the available-for-sale debt security before the recovery of its amortized cost basis. If either condition is met, the Company will recognize a full impairment charge to earnings. For all other available-for-sale debt securities that don't meet either condition and that have expected credit losses, the credit loss will be recognized in earnings. Any non-credit related loss impairment related to all other factors will be recorded in other comprehensive income (loss).

Management also assesses the nature of the unrealized losses taking into consideration factors such as changes in risk-free interest rates, general credit spread changes, market supply and demand, creditworthiness of the issuer, and quality of the underlying collateral.

Non-GAAP Financial Measures

In addition to results presented in accordance with U.S. GAAP, this quarterly report on Form 10-Q contains certain non-GAAP financial measures, including operating net income, operating noninterest expense, operating noninterest income, operating earnings per share, basic, operating earnings per share, diluted, operating return on average assets, operating return on average shareholders’ equity, operating efficiency ratio, tangible shareholders’ equity, tangible assets, tangible book value per share, and efficiency ratio. The Company’s management believes that the supplemental non-GAAP 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 determined in accordance with U.S. GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.

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.

Comparison of Financial Condition as of June 30, 2025 and December 31, 2024

Total Assets. Total assets increased $68.8 million, or 1.3%, to $5.23 billion as of June 30, 2025 from $5.16 billion as of December 31, 2024. The increase was primarily driven by increases in net loans, non-public investments and available-for-sale securities, offset partially by decreases in cash and cash equivalents and BOLI.

Cash and Cash Equivalents. Cash and cash equivalents decreased $105.2 million, or 28.9%, to $258.7 million as of June 30, 2025 from $363.9 million as of December 31, 2024. The decrease in cash and cash equivalents was primarily a result of increased loan originations and the repurchase of 3,241,874 shares during the six months ended June 30, 2025.

Securities Available for Sale. Securities available for sale increased $7.2 million, or 3.2%, to $235.4 million as of June 30, 2025 from $228.2 million as of December 31, 2024 due to purchases of U.S. treasuries, government agency debt securities and mortgage backed securities.

Loans. Net loans increased $204.2 million, or 4.8%, to $4.50 billion as of June 30, 2025 from $4.29 billion as of December 31, 2024. The increase resulted primarily from increases in: construction and land development loans, which increased $140.5 million, or 24.1% and commercial and industrial loans, which increased $65.4 million, or 11.7%. The increase in our loan portfolio reflects our strategy to prudently grow the balance sheet by continuing to diversify into these higher-yielding loans to improve net margins and manage interest rate risk.

The Company had approximately $441.9 million and $459.6 million in loans to borrowers in the cannabis industry at June 30, 2025 and December 31, 2024, respectively. Of that total, $268.3 million and $321.9 million were direct loans to cannabis companies and were collateralized by real estate at June 30, 2025 and December 31, 2024, respectively.

Non-Public Investments. Non-public investments consist primarily of equity investments and FHLB and FRB stock holdings. These assets increased $11.4 million, or 46.8%, to $35.8 million as of June 30, 2025 from $24.4 million as of December 31, 2024. The increase resulted primarily from a new solar tax credit equity investment of $6.8 million, as well as increases in FHLB stock and FRB stock holdings of $1.1 million and $860,000, respectively.

BOLI. During the three and six months ended June 30, 2025, the Company received proceeds on surrendered BOLI policies of $48.8 million. The Company surrendered BOLI policies in September 2024, which allowed the insurance carriers a period of time to payout the proceeds, resulting in the Company carrying higher BOLI balances prior to the receipt of the proceeds from the surrender.

Deposits. Deposits increased $90.4 million, or 2.2%, to $4.27 billion as of June 30, 2025 from $4.18 billion as of December 31, 2024. Core deposits (which we define as all deposits including certificates of deposit, other than brokered deposits) increased $146.0 million, or 3.8%, to $4.01 billion as of June 30, 2025 from $3.87 billion as of December 31, 2024. The increase in deposits was the result of growth in customer deposits, primarily money market accounts, which increased $92.3 million, or 9.2%, noninterest-bearing demand deposits, which increased $22.4 million or 3.6%, savings accounts, which increased $12.8 million, or 11.8%, and customer time deposits, which increased $12.4 million, or 0.7%, from December 31, 2024. The increase in core deposits was partially offset by a decrease in brokered deposits of $55.6 million, or 18.0%, due to higher utilization of FHLB borrowings to fund loan growth and better rates on borrowings compared to brokered deposits.

The Company had $408.9 million and $395.2 million in deposits from the cannabis industry as of June 30, 2025 and December 31, 2024, respectively.

FHLB Borrowings. FHLB borrowings increased $6.8 million, or 5.6%, to $127.6 million as of June 30, 2025 from $120.8 million as of December 31, 2024. The increase in FHLB borrowings was the result of loan growth and brokered deposit maturities.

Shareholders’ Equity. Total shareholders’ equity decreased $28.0 million, or 3.7%, to $737.1 million as of June 30, 2025 from $765.2 million as of December 31, 2024, due to the $59.6 million decrease in additional paid-in capital resulting from the completion of the first share repurchase program and the initiation of the second repurchase program, partially offset by net income of $27.3 million during the six months ended June 30, 2025.

Comparison of Operating Results for the Three Months Ended June 30, 2025 and 2024

Net Income. Net income was $14.6 million for the quarter ended June 30, 2025, compared to net income of $9.5 million for the quarter ended June 30, 2024, an increase of approximately $5.1 million, or 54.2%. An increase of $8.3 million, or 21.4%, in net interest income and a $1.2 million, or 40.2%, increase in noninterest income was partially offset by a $3.1 million, or 11.8%, increase in noninterest expense and a $1.8 million, or 74.8%, increase in income tax expense.

Operating net income, excluding one-time charges, amounted to $15.0 million, or $0.40 per basic and diluted share for the quarter ended June 30, 2025 compared to operating net income, excluding one-time charges, of $9.9 million, or $0.25 per basic and diluted share, for the quarter ended June 30, 2024, an increase of $5.2 million, or 52.6%. The material one-time charges for the three months ended June 30, 2025 were:

• Merger and acquisition costs of $530,000 related to the Company’s pending acquisition of Provident Bancorp Inc. and BankProv and;
• Income tax expense and a modified endowment contract penalty related to the surrender of BOLI policies of $64,000.

Compared to the material one-time charges for the three months ended June 30, 2024:

• Proportional amortization expense of $506,000 for the adoption of ASU 2023-02

Interest and Dividend Income. Interest and dividend income increased $8.7 million, or 12.3%, to $79.8 million for the quarter ended June 30, 2025 from $71.1 million for the quarter ended June 30, 2024, primarily due to a $9.4 million, or 14.5%, increase in interest and fees on loans. The increase in interest and fees on loans was primarily due to an increase of $492.2 million, or 12.3%, in the average balance of the loan portfolio to $4.48 billion for the quarter ended June 30, 2025 from $3.99 billion for the quarter ended June 30, 2024 and an increase of 11 basis points in the weighted average yield for the loan portfolio to 6.69% for the quarter ended June 30, 2025 from 6.58% for the quarter ended June 30, 2024, reflecting the growth of our commercial and construction loan portfolios. The increase in interest and fees on loans was partially offset by an $80.3 million decrease in the average balance of short-term investments to $199.3 million for the quarter ended June 30, 2025 from $279.6 million for the quarter ended June 30, 2024, as well as, a decrease of 109 basis points in the weighted average yield for the short-term investment portfolio to 4.46% for the quarter ended June 30, 2025 from 5.56% for the quarter ended June 30, 2024, driven by the reduction in cash from the share repurchase plans.

Average interest-earning assets increased $444.3 million, or 9.9%, to $4.94 billion for the quarter ended June 30, 2025 from $4.50 billion for the quarter ended June 30, 2024. The yield on interest-earning assets increased 12 basis points to 6.48% for the quarter ended June 30, 2025 from 6.36% for the quarter ended June 30, 2024.

Interest Expense. Total interest expense increased $441,000, or 1.4%, to $32.8 million for the quarter ended June 30, 2025 from $32.4 million for the quarter ended June 30, 2024. Interest expense on borrowings increased $330,000, or 40.2%, to $1.2 million for the quarter ended June 30, 2025 from $821,000 for the quarter ended June 30, 2024 primarily from the increased utilization of FHLB borrowings due to brokered deposit maturities. Interest expense on deposits increased $111,000, or 0.35%, to $31.7 million for the quarter ended June 30, 2025 from $31.6 million for the quarter ended June 30, 2024.

The increase was primarily due to an increase in the average balance of money market accounts of $253.2 million, or 30.3%, to $1.09 billion for the quarter ended June 30, 2025 from $836.9 million for the quarter ended June 30, 2024, an increase in the average balance of certificates of deposit and individual retirement accounts of $130.4 million, or 7.1%, to $1.96 billion for the quarter ended June 30, 2025 from $1.83 billion for the quarter ended June 30, 2024, offset by a decrease in the weighted average rate on certificates of deposit and individual retirement accounts of 70 basis points to 4.34% for the quarter ended June 30, 2025 from 5.04% for the quarter ended June 30, 2024.

Net Interest Income. Net interest income increased $8.3 million, or 21.4%, to $47.0 million for the quarter ended June 30, 2025 from $38.7 million for the quarter ended June 30, 2024, primarily due to a $444.3 million, or 9.9%, increase in the average balance of interest-earning assets to $4.94 billion for the quarter ended June 30, 2025 from $4.50 billion for the quarter ended June 30, 2024, a decrease in the weighted average rate on interest-bearing liabilities of 41 basis points from 3.93% for the quarter ended June 30, 2024 to 3.52% for the quarter ended June 30, 2025 and an increase in the weighted average rate on interest-bearing assets of 12 basis points from 6.36% for the quarter ended June 30, 2024 to 6.48% for the quarter ended June 30, 2025. These increases were partially offset by an increase in the average balance of interest-bearing liabilities of $431.3 million, or 13.0%, to $3.75 billion at June 30, 2025 from $3.32 billion at June 30, 2024.

Provision for Credit Losses. Based on management’s analysis of the adequacy of the ACL, a provision of $3.2 million was recorded for the quarter ended June 30, 2025, of which $4.2 million related to the provision for credit losses on loans, compared to a provision of $3.7 million for the quarter ended June 30, 2024, which included a $4.4 million provision for credit losses on loans. The release of provision for credit losses on unfunded commitments increased $321,000 during the three months ended June 30, 2025 as a result of a decrease in the WARM period on construction loans and a reduction in the probability of funding on construction commitments. The decrease of $506,000, or 13.8%, in the total provision for credit losses was primarily due to the $923,000 recovery on a commercial real estate participation loan during the three months ended June 30, 2025.

Noninterest Income. Noninterest income increased $1.2 million, or 40.2%, to $4.2 million for the quarter ended June 30, 2025 from $3.0 million for the quarter ended June 30, 2024. The increase resulted primarily from increases in customer service fees of $682,000, or 36.4%, due to higher loan and cash management fees, increases in the change in the cash surrender value of BOLI of $383,000, or 94.8%, resulting from carrying a higher balance of BOLI and increased SWAP contract fees of $259,000, or 97.7%, from an increase in the volume of closed customer SWAPs during the three months ended June 30, 2025; offset partially by decreases in mortgage banking income of $287,000, or 67.1%, resulting from a decrease in the volume of loans sold during the quarter ended June 30, 2025.

The table below sets forth our noninterest income for the quarters ended June 30, 2025 and 2024:

Noninterest Expense. Noninterest expense increased $3.1 million, or 11.8%, to $29.3 million for the quarter ended June 30, 2025 from $26.2 million for the quarter ended June 30, 2024. Salaries and employee benefit expenses increased $1.8 million, or 10.9%, resulting primarily from a $1.4 million increase in employee compensation, a $366,000 increase in medical and dental benefits and a $212,000 increase in payroll taxes, all due to headcount increases related to the Company’s continued growth, a $262,000 increase in stock-based compensation as a result of the grants made during the current quarter and a $214,000 increase in ESOP compensation resulting from the Company’s stock price appreciation; partially offset by a $967,000 decrease in LTIP expenses resulting from reduced balances in the LTIP during the quarter ended June 30, 2025. Director and professional service fees increased $673,000, or 29.7%, primarily driven by $527,000 in stock compensation to directors related to grants made during the quarter ended June 30, 2025 and a $140,000 increase in Director’s fee expenses.

Merger and acquisition expenses increased $530,000 from $0 resulting from the announcement of the Provident Bancorp, Inc. and BankProv acquisition during the quarter ended June 30, 2025.

Income Tax Expense. Income tax expense increased $1.8 million, or 74.8%, to $4.1 million for the quarter ended June 30, 2025 from $2.4 million for the quarter ended June 30, 2024. The effective tax rate was 22.1% and 20.0% for the quarter ended June 30, 2025 and 2024, respectively. The increase in tax expense was from higher pre-tax income and an increase in projected pass through losses on solar income tax credit investments during the quarter ended June 30, 2025 compared to June 30, 2024.

Average Balances and Yields. The following table sets forth average balance sheets, average yields and costs, and certain other information for the periods indicated. No tax-equivalent yield adjustments have been made, as the effects would be immaterial. Non-accrual loans were included in the computation of average balances. All average balances are daily average balances. The yields set forth below include the effect of deferred fees, discounts, and premiums that are amortized or accreted to interest income or interest expense; such fees, discounts and premiums were not material for the periods presented.

(1) Net interest rate spread represents the difference between the weighted average yield on interest-earning assets and the weighted average rate of interest-bearing liabilities.

(2) Net interest-earning assets represent total interest-earning assets less total interest-bearing liabilities.

(3) Net interest margin represents net interest income divided by average total interest-earning assets.

(4) Annualized.

(5) Other investments are comprised of FRB stock, FHLB stock and swap collateral accounts. Short-term investments are comprised of cash and cash equivalents

Rate/Volume Analysis. The following table presents the effects of changing rates and volumes on our net interest income for the periods indicated. The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The total column represents the sum of the prior columns. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately based on the changes due to volume and the changes due to rate. There were no out-of-period items or adjustments required to be excluded from the table below.

The increase was primarily due to an increase in the average balance of money market accounts of $236.8 million, or 28.0% to $1.08 million for the six months ended June 30, 2025 from $844.9 million for the six months ended June 30, 2024 and an increase in the average balance of certificate of deposit and individual retirement accounts of $220.1 million, or 12.6%, to $1.97 billion for the six months ended June 30, 2025 from $1.75 billion for the six months ended June 30, 2024, partially offset by a decrease in the weighted average rate on certificate of deposit and individual retirement accounts of 51 basis points to 4.46% for the six months ended June 30, 2025 from 4.97% for the six months ended June 30, 2024.

Net Interest Income. Net interest income increased $13.2 million, or 17.0%, to $90.5 million for the six months ended June 30, 2025 from $77.4 million for the six months ended June 30, 2024, primarily due to a $518.1 million, or 11.8%, increase in the average balance of interest-earning assets to $4.91 billion for the six months ended June 30, 2025 from $4.40 billion for the six months ended June 30, 2024 and an increase in the weighted average yield on interest-earning assets of 6 basis points to 6.43% for the six months ended June 30, 2025 from 6.37% for the six months ended June 30, 2024 and a decrease in the weighted average rate on interest-bearing liabilities of 30 basis points to 3.57% for the six months ended June 30, 2025 from 3.87% for the six months ended June 30, 2024. These increases were offset partially by an increase in the average balance of interest-bearing liabilities of $516.6 million, or 16.0%, to $3.74 billion for the six months ended June 30, 2025 from $3.22 billion for the six months ended June 30, 2024.

Provision for Credit Losses. Based on management’s analysis of the adequacy of the ACL, a provision of $4.3 million was recorded for the six months ended June 30, 2025, of which $5.2 million related to the provision for credit losses on loans, compared to a provision of $8.1 million for the six months ended June 30, 2024, which included an $8.3 million provision for credit losses on loans. The release of provision for credit losses on unfunded commitments increased $649,000, or 291.0%, during the six months ended June 30, 2025 as a result of a decrease in the WARM period on construction loans and a reduction in the probability of funding on construction commitments. The decrease of $3.8 million, or 46.7%, in the total provision for credit losses was primarily due to the establishment of a $4.0 million specific reserve for a commercial real estate participation loan that was recorded during the six months ended June 30, 2024, with no increase in specific reserves necessary during the six months ended June 30, 2025. The commercial real estate participation loan was ultimately resolved with a $923,000 recovery during the six months ended June 30, 2025.

Noninterest Income. Noninterest income increased $1.6 million, or 24.0%, to $8.0 million for the six months ended June 30, 2025 from $6.5 million for the six months ended June 30, 2024. The increase resulted primarily from increases in customer service fees of $1.4 million, or 36.2%, due to higher loan and cash management fees and increases in the change in the cash surrender value of BOLI of $1.0 million, or 125.8%, resulting from carrying a higher balance of BOLI during the six months ended June 30, 2025; offset partially by decreases in other income of $454,000 resulting from the $610,000 debit card branding signing bonus earned during the six months ended June 30, 2024, offset partially by the annual $160,000 debit card incentive bonus earned during the six months ended June 30, 2025. The table below sets forth our noninterest income for the six months ended June 30, 2025 and 2024:

Noninterest Expense. Noninterest expense increased $6.2 million, or 11.9%, to $58.0 million for the six months ended June 30, 2025 from $51.8 million for the six months ended June 30, 2024. Salaries and employee benefit expenses increased $3.4 million, or 9.9%, primarily from a $2.0 million increase in employee compensation expense, a $707,000 increase in medical and dental benefits expense and a $387,000 increase in payroll taxes from the hiring of additional employees consistent with our growth, an $828,000 increase in pension expense due to a $1.2 million final liquidation contribution, a $409,000 increase in ESOP compensation expense as a result of the Company’s stock price appreciation and a $262,000 increase in stock compensation expense from restricted stock award grants during the six months ended June 30, 2025; offset partially by a $1.6 million decrease in LTIP expenses resulting from reduced balances in the LTIP during the quarter ended June 30, 2025. Data processing expenses increased $938,000, or 21.7%, during the six months ended June 30, 2025, primarily the result of higher management information and general servicing system expenses. Director and professional service fees increased $912,000, or 21.8%, during the six months ended June 30, 2025, primarily the result of $527,000 in director stock compensation expense from restricted stock award grants during the six months ended June 30, 2025, a $273,000 increase in director’s fee expenses, a $135,000 increase in legal expenses and a $124,000 increase in consulting expenses. FDIC and state assessment expenses increased $702,000, or 70.6%, due to increases in the related assessment calculations resulting from the Bank’s growth. Merger and acquisition expenses increased $530,000 from $0 due to the announcement of the Company’s acquisition of Provident Bancorp, Inc. and BankProv. The table below sets forth our noninterest expense for the six months ended June 30, 2025 and 2024:

Income Tax Expense. Income tax expense increased $3.2 million, or 55.9%, to $9.1 million for the six months ended June 30, 2025 from $5.8 million for the six months ended June 30, 2024, mainly resulting from the increase in net income during the quarter ended June 30, 2025. The effective tax rate was 25.0% and 24.2% for the six months ended June 30, 2025 and 2024, respectively.

Average Balances and Yields. The following table sets forth average balance sheets, average yields and costs, and certain other information for the periods indicated. No tax-equivalent yield adjustments have been made, as the effects would be immaterial. Non-accrual loans were included in the computation of average balances. All average balances are daily average balances. The yields set forth below include the effect of deferred fees, discounts, and premiums that are amortized or accreted to interest income or interest expense; such fees, discounts and premiums were not material for the periods presented.

(1) Net interest rate spread represents the difference between the weighted average yield on interest-earning assets and the weighted average rate of interest-bearing liabilities.

(2) Net interest-earning assets represent total interest-earning assets less total interest-bearing liabilities.

(3) Net interest margin represents net interest income divided by average total interest-earning assets.

(4) Annualized.

(5) Other investments are comprised of FRB stock, FHLB stock and swap collateral accounts. Short-term investments are comprised of cash and cash equivalents

Rate/Volume Analysis. The following table presents the effects of changing rates and volumes on our net interest income for the periods indicated. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The total column represents the sum of the prior columns. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately based on the changes due to rate and the changes due to volume. There were no out-of-period items or adjustments required to be excluded from the table below.

Liquidity and Capital Resources

Liquidity describes our ability to meet the financial obligations that arise in the ordinary course of business. Liquidity is primarily needed to meet the borrowing and deposit withdrawal requirements of our customers and to fund current and planned expenditures. Our primary sources of funds are deposits, principal and interest payments on loans and securities, and proceeds from maturities of securities. We are also able to borrow from the FHLB and the Discount Window at the Federal Reserve Bank of Boston (“FRB”). As of June 30, 2025, we had outstanding advances of $127.6 million from the FHLB. As of June 30, 2025, we had unused borrowing capacity of $724.2 million with the FHLB. At June 30, 2025, the Bank had $593.4 million available from the discount window under the Borrower in Custody (“BIC”) program at the FRB. Additionally, as of June 30, 2025, we had $254.2 million of brokered deposits and pursuant to our internal liquidity policy, which allows us to utilize brokered deposits up to 25.0% of our total assets, we had an additional capacity of up to approximately $1.05 billion of brokered deposits.

While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows and loan prepayments are greatly influenced by general interest rates, economic conditions, and competition. Our most liquid assets are cash and short-term investments. The levels of these assets are dependent on our operating, financing, lending, and investing activities during any given period.

Our cash flows are comprised of three primary classifications: cash flows from operating activities, investing activities, and financing activities.

At June 30, 2025, we had $35.5 million in commitments to originate loans outstanding. In addition, we had $584.3 million in unused lines of credit to borrowers, $434.3 million in unadvanced construction loans and $5.7 million in letters of credit outstanding.

Non-brokered certificates of deposit due within one year of June 30, 2025 totaled $1.58 billion, or 36.9%, of total deposits. If these deposits do not remain with us, we may be required to seek other sources of funds, including brokered deposits, FHLB advances and FRB borrowings. Depending on market conditions, we may be required to pay higher rates on such deposits or other borrowings than we currently pay on the non-brokered certificates of deposit due on or before June 30, 2026, or on our other interest-bearing deposit accounts. We believe, however, based on historical experience and current market interest rates that we will retain upon maturity a large portion of our certificates of deposit with maturities of one year or less as of June 30, 2025.

Our primary investing activity is originating loans. During the six months ended June 30, 2025, we originated $212.8 million of loans, net of repayments.

Financing activities consist primarily of activity in deposit accounts and FHLB advances. We experienced net increases in deposits of $90.4 million for the six months ended June 30, 2025. At June 30, 2025 and December 31, 2024, the level of brokered time deposits was $254.2 million and $309.8 million, respectively. Deposit flows are affected primarily by the overall level of interest rates and the interest rates and products offered by us and our competitors. FHLB advances decreased $6.8 million during the six months ended June 30, 2025.

For additional information, see the consolidated statements of cash flows for the six months ended June 30, 2025 and 2024 included as part of the consolidated financial statements appearing elsewhere in this Form 10-Q.

We are committed to maintaining a strong liquidity position. We continuously monitor our liquidity position and adjustments are made to the balance between sources and uses of funds as deemed appropriate by management. Liquidity risk management is an important element in our asset/liability management process. We regularly model liquidity stress scenarios to assess potential liquidity outflows or funding problems resulting from economic disruptions, volatility in the financial markets, unexpected credit events or other significant occurrences deemed problematic by management. These scenarios are incorporated into our contingency funding planning process, which provides the basis for the identification of our liquidity needs. We anticipate that we will have sufficient funds to meet our current funding commitments. In addition, based on our deposit retention experience and current pricing strategy, we anticipate that a significant portion of maturing time deposits will be retained.

As of June 30, 2025, Needham Bank and NB Bancorp, Inc. exceeded all of their regulatory capital requirements, and were categorized as well-capitalized at that date. Management is not aware of any conditions or events since the most recent notification of well-capitalized status that would change our category. See Note 10 of the notes to consolidated financial statements.

Impact of Inflation and Changing Prices

The consolidated financial statements and related data presented in this Form 10-Q have been prepared in accordance with U.S. GAAP, which requires the measurement of financial position and operating results in terms of historical dollars without considering changes in the relative purchasing power of money over time due to inflation. The primary impact of inflation on our operations is reflected in increased operating costs. Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates, generally, have a more significant impact on a financial institution’s performance than does inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

An evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended) as of June 30, 2025. Based on that evaluation, the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, concluded that the Registrant’s disclosure controls and procedures were effective.

During the quarter ended June 30, 2025, there have been no changes in the Company’s internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

There have been no material changes in risk factors applicable to the Company from those disclosed in “Risk Factors” in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
