These statements may be identified by such forward-looking terminology as “expect,” “achieve,” “plan,” “believe,” “outlook”, “projected”, “future,” “positioned,” “continued,” “will,” “would,” “potential,” “anticipated,” “guidance,” “targeted” or similar statements or variations of such terms. Actual results may differ from those contemplated by these forward-looking statements. Factors that may cause actual results to differ materially from those contemplated by such forward-looking statements include, but are not limited to: • adverse economic conditions in the regional and local economies within the New England region and the Company’s market area; • events impacting the financial services industry, including high profile bank failures, and any resulting decreased confidence in banks among depositors, investors, and other counterparties, as well as competition for deposits and significant disruption, volatility and depressed valuations of equity and other securities of banks in the capital markets; • the effects to the Company of an increasingly competitive labor market, including the possibility that the Company will have to devote significant resources to attract and retain qualified personnel; • political and policy uncertainties in the U.S., changes in U.S. and international trade policies, such as tariffs, trade wars or related uncertainties, new or proposed legislation or other factors, and the potential impact of such factors on the Company and its customers, including the potential for decreases in deposits and loan demand, unanticipated loan delinquencies, loss of collateral and decreased service revenues; • the instability or volatility in financial markets and unfavorable domestic or global general economic, political or business conditions, whether caused by geopolitical concerns, including the Russia/Ukraine conflict, the conflicts in Israel, Iran and surrounding areas and the possible expansion of such conflicts; • unanticipated loan delinquencies, loss of collateral, decreased service revenues, and other potential negative effects on the Company’s local economies or the Company's business caused by adverse weather conditions and natural disasters, changes in climate, public health crises or other external events and any actions taken by governmental authorities in response to any such events; • adverse changes or volatility in the local real estate market; • changes in interest rates and any resulting impact on interest earning assets and/or interest bearing liabilities, the level of voluntary prepayments on loans and the receipt of payments on mortgage-backed securities, decreased loan demand or increased difficulty in the ability of borrowers to repay variable rate loans; • risks related to the Company’s acquisition of Enterprise Bancorp (“Enterprise”) and acquisitions generally, including disruption 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; • the effect of laws, regulations, new requirements or expectations, or additional regulatory oversight in the highly regulated financial services industry, and the resulting need to invest in technology to meet heightened regulatory expectations, increased costs of compliance or required adjustments to strategy; • changes in trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; • higher than expected tax expense, including as a result of failure to comply with general tax laws and changes in tax laws; • increased competition in the Company’s market areas, including competition that could impact deposit gathering, retention of deposits and the cost of deposits, increased competition due to the demand for innovative products and service offerings, and competition from non-depository institutions which may be subject to fewer regulatory constraints and lower cost structures; • a deterioration in the conditions of the securities markets; • a deterioration of the credit rating for U.S. long-term sovereign debt or uncertainties surrounding the federal budget; • inability to adapt to changes in information technology, including changes to industry accepted delivery models driven by a migration to the internet as a means of service delivery, including any inability to effectively implement new technology-driven products, such as artificial intelligence; • electronic or other fraudulent activity within the financial services industry, especially in the commercial banking sector; • adverse changes in consumer spending and savings habits; • the effect of laws and regulations regarding the financial services industry, including the need to invest in technology to meet heightened regulatory expectations or the introduction of new requirements or expectations resulting in increased costs of compliance or required adjustments to strategy; • changes in laws and regulations, or new laws or regulations (including laws and regulations concerning taxes, banking, securities and insurance) generally applicable to the Company’s business and the associated costs of such changes or new laws and regulations; • the Company’s potential judgments, claims, damages, penalties, fines and reputational damage resulting from pending or future litigation and regulatory and government actions; • changes in accounting policies, practices and standards, as may be adopted by the regulatory agencies as well as the Public Company Accounting Oversight Board, the Financial Accounting Standards Board, and other accounting standard setters; • operational risks related to the Company and its customers’ reliance on information technology; cyber threats, attacks, intrusions, and fraud; and outages or other issues impacting the Company or its third party service providers which could lead to interruptions or disruptions of the Company’s operating systems, including systems that are customer facing, and adversely impact the Company’s business; and • any unexpected material adverse changes in the Company’s operations or earnings. The Company wishes to caution readers not to place undue reliance on any forward-looking statements as the Company’s business and its forward-looking statements involve substantial known and unknown risks and uncertainties described in the Company’s Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q (“Risk Factors”).

23 This presentation contains financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This information may include operating net income and operating earnings per share (“EPS”), operating return on average assets, operating return on average common equity, operating return on average tangible common equity, core net interest margin (“core NIM” or “core margin”) and the associated core loan yield, tangible book value per share, tangible common equity ratio and return on average tangible common equity. Management reviews its core margin to determine any items that may impact the net interest margin that may be one-time in nature or not reflective of its core operating environment, such as low-yielding loans originated through government programs in response to the pandemic, or significant purchase accounting adjustments, or other adjustments such as nonaccrual interest reversals/recoveries and prepayment penalties. Management believes that adjusting for these items to arrive at a core margin provides additional insight into the operating environment and how management decisions impact the net interest margin. Management also supplements its evaluation of financial performance with analysis of tangible book value per share (which is computed by dividing stockholders’ equity less goodwill and identifiable intangible assets, or “tangible common equity”, by common shares outstanding), the tangible common equity ratio (which is computed by dividing tangible common equity by “tangible assets”, defined as total assets less goodwill and other intangibles), and return on average tangible common equity (which is computed by dividing net income by average tangible common equity). The Company has included information on tangible book value per share, the tangible common equity ratio and return on average tangible common equity because management believes that investors may find it useful to have access to the same analytical tools used by management. As a result of merger and acquisition activity, the Company has recognized goodwill and other intangible assets in conjunction with business combination accounting principles. Excluding the impact of goodwill and other intangibles in measuring asset and capital values for the ratios provided, along with other bank standard capital ratios, provides a framework to compare the capital adequacy of the Company to other companies in the financial services industry. These non-GAAP measures should not be viewed as a substitute for operating results and other financial measures determined in accordance with GAAP. An item which management deems to be noncore and excludes when computing these non-GAAP measures can be of substantial importance to the Company’s results for any particular quarter or year. The Company’s non-GAAP performance measures, including operating net income, operating EPS, operating return on average assets, operating return on average common equity, core margin, tangible book value per share and the tangible common equity ratio, are not necessarily comparable to non-GAAP performance measures which may be presented by other companies.
