Forward-looking statements include statements regarding anticipated future events and can be identified by the fact that they do not relate strictly to historical or current facts. You can identify these statements from the use of the words “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target” and similar expressions. Forward-looking statements, by their nature, are subject to risks and uncertainties. There are many factors that could cause actual results to differ materially from expected results described in the forward-looking statements. Certain factors that could cause actual results to differ materially from expected results include developments in the Company’s market relating to the COVID-19 pandemic, including the severity and duration of the associated economic slowdown, adverse developments in the level and direction of loan delinquencies and charge-offs and changes in estimates of the adequacy of the allowance for loan losses, increased competitive pressures, changes in the interest rate environment, risks that revenue or expense synergies or the other expected benefits of the Company's merger with Century ("Transaction") may not fully materialize for the Company in the timeframe expected or at all, or may be more costly to achieve; that the Company is unable to successfully implement integration strategies; reputational risks and the reaction of customers to the Transaction; and diversion of management time on Transaction-related issues, as well as general economic conditions or conditions within the securities markets, and legislative and regulatory changes that could adversely affect the business in which the Company and its subsidiary Eastern Bank are engaged, including inflation, interest rates, interest rate sensitivity and liquidity, including the effect of, and changes in, monetary and fiscal policies and laws, such as the interest rate policies of the Board of Governors of the Federal Reserve System; market and monetary fluctuations, including fluctuations due to actual or anticipated changes to federal tax laws; and credit quality, including adverse developments in local or regional real estate markets that decrease collateral values associated with existing loans and the failure of the Company to execute all of its planned share repurchases. For further discussion of such factors, please see the Company’s most recent Annual Report on Form 10-K and subsequent filings with the U.S. Securities and Exchange Commission (the “SEC”), which are available on the SEC’s website at www.sec.gov. Further, given the ongoing and dynamic nature of the COVID-19 pandemic, it is difficult to predict what continued effects the COVID-19 pandemic will have on the Company's business and results of operations. The COVID-19 pandemic and the related local and national economic disruption may result in a continued decline in demand for the Company's products and services; increased levels of loan delinquencies, problem assets and foreclosures; an increase in the Company's allowance for loan losses; a decline in the value of loan collateral, including real estate; reduced demand for office space in our markets due to remote and/or hybrid work arrangements; a greater decline in the yield on the Company's interest-earning assets than the decline in the cost of the Company's interest-bearing liabilities; and increased cybersecurity risks, as employees continue to work remotely. Accordingly, you should not place undue reliance on forward-looking statements, which reflect the Company's expectations only as of the date of this presentation. The Company does not undertake any obligation to update forward-looking statements.

A non-GAAP financial measure is defined as a numerical measure of the Company’s historical or future financial performance, financial position or cash flows that excludes (or includes) amounts, or is subject to adjustments that have the effect of excluding (or including) amounts that are included in the most directly comparable measure calculated and presented in accordance with accounting principles generally accepted in the United States (“GAAP”) in the Company’s statement of income, balance sheet or statement of cash flows (or equivalent statements). The Company presents non-GAAP financial measures, which management uses to evaluate the Company’s performance, and which exclude the effects of certain transactions that management believes are unrelated to its core business and are therefore not necessarily indicative of its current performance or financial position. Management believes excluding these items facilitates greater visibility for investors into the Company’s core businesses as well as underlying trends that may, to some extent, be obscured by inclusion of such items in the corresponding GAAP financial measures. There are items in the Company’s financial statements that impact its financial results, but which management believes are unrelated to the Company’s core business. Accordingly, the Company presents noninterest income on an operating basis, total operating revenue, noninterest expense on an operating basis, operating net income, operating earnings per share, operating return on average assets, operating return on average shareholders’ equity, the operating efficiency ratio, and the ratio of noninterest income to total revenue on an operating basis. Each of these figures excludes the impact of such applicable items because management believes such exclusion can provide greater visibility into the Company’s core business and underlying trends. Such items that management does not consider to be core to the Company’s business include (i) income and expenses from investments held in rabbi trusts, (ii) gains and losses on sales of securities available for sale, net, (iii) gains and losses on the sale of other assets, (iv) rabbi trust employee benefits, (v) impairment charges on tax credit investments and associated tax credit benefits, (vi) expenses indirectly associated with the Company’s initial public offering (“IPO”), (vii) other real estate owned (“OREO”) gains, (viii) merger and acquisition expenses, (ix) the stock donation to the Eastern Bank Foundation (“EBF”), formerly known as the Eastern Bank Charitable Foundation) in connection with the Company’s mutual-to-stock conversion and IPO, and (x) settlement of putative consumer class action litigation matters related to overdraft and non-sufficient funds fees, and associated settlement expenses. The Company does not provide an outlook for its total noninterest income and total noninterest expense because each contains income or expense components, as applicable, such as income associated with rabbi trust accounts and rabbi trust employee benefit expense, which are market-driven, and over which the Company cannot exercise control. Accordingly, reconciliations of the Company’s outlook for its noninterest income on an operating basis and its noninterest expense on an operating basis to an outlook for total noninterest income and total noninterest expense, respectively, cannot be made available without unreasonable effort. Management also presents the Company’s core net interest margin which excludes the impact of items management determines as being one-time in nature or not indicative of its core operating results. Such items include the impact of excess liquidity in the form of excess cash volume, Small Business Administration ("SBA") Paycheck Protection Program ("PPP") loans originated in response to the COVID-19 pandemic, and material purchase accounting adjustments. Similarly, management presents certain asset quality metrics excluding PPP loans which it does not consider to be part of the Company’s core portfolios. These metrics include the ratio of total nonperforming loans to total loans excluding PPP loans, the ratio of the allowance for loan losses to total loans excluding PPP loans, and the ratio of annualized net charge-offs to average total loans excluding PPP loans. The Company does not provide an outlook for its ratio of the allowance for loan losses to total loans because it contains components, such as the volume of PPP loans which is market-driven, over which the Company cannot exercise control. Accordingly, a reconciliation of the Company’s outlook for its ratio of the allowance for loan losses to total loans to an outlook for its ratio of the allowance for loan losses to total loans excluding PPP loans cannot be made available without unreasonable effort. The Company does not provide an outlook for its ratio of annualized net charge-offs to average total loans because it contains components, such as the volume PPP loans which is market- driven, over which the Company cannot exercise control. Accordingly, a reconciliation of the Company’s outlook for its ratio of annualized net charge-offs to average total loans to an outlook for its ratio of annualized net charge-offs to average total loans excluding PPP loans cannot be made available without unreasonable effort. The Company anticipates that the vast majority of its PPP loans outstanding at December 31, 2021 will be forgiven, and to the extent not forgiven, a PPP loan is intended to be 100% guaranteed by the SBA. Management also presents tangible assets, tangible shareholders’ equity, tangible book value per share, and the ratio of tangible shareholders’ equity to tangible assets, each of which excludes the impact of goodwill and other intangible assets, as management believes these financial measures provide investors with the ability to further assess the Company’s performance, identify trends in its core business and provide a comparison of its capital adequacy to other companies. The Company included the tangible ratios because management believes that investors may find it useful to have access to the same analytical tools used by management to assess performance and identify trends. These non-GAAP financial measures presented in this presentation should not be considered an alternative or substitute for financial results or measures determined in accordance with GAAP or as an indication of the Company’s cash flows from operating activities, a measure of its liquidity position or an indication of funds available for its cash needs. An item which management considers to be non-core and excludes when computing these non-GAAP measures can be of substantial importance to the Company’s results for any particular period. In addition, management’s methodology for calculating non-GAAP financial measures may differ from the methodologies employed by other banking companies to calculate the same or similar performance measures, and accordingly, the Company’s reported non-GAAP financial measures may not be comparable to the same or similar performance measures reported by other banking companies. Please refer to Appendices A-E for a reconciliations of the Company's GAAP financial measures to the non-GAAP financial measures in this presentation. Non-GAAP financial measures

("Century"), adding approximately $7 billion of total assets, $3 billion of total loans and $6 billion of total deposits. A full system conversion was successfully completed prior to the open of business on November 15, 2021. ■ Organic loan growth, excluding Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”) loans, was $133.6 million, or 6% on an annualized basis. Organic commercial loan growth, excluding PPP loans, was $115.4 million, or 7% on an annualized basis. ■ An improving economic outlook coupled with strong asset quality led to a $4.3 million release of allowance for loan losses. ■ The Company recorded a tax benefit of $2.9 million in the fourth quarter, compared to expense of $11.3 million in the prior quarter, a decrease of $14.2 million primarily attributable to an $11.3 million release of the deferred tax valuation allowance recorded in connection with the Company’s fourth quarter 2020 donation of stock to the Eastern Bank Foundation (“EBF”) in connection with the Company’s initial public offering. ■ The Board of Directors has approved a 25% increase in the quarterly dividend to $0.10 per share for the first quarter. ■ The Company repurchased 1,135,878 shares of its common stock during the fourth quarter of 2021 at a weighted average price of $20.42, excluding commissions, representing a total market value of $23.2 million. *Non-GAAP Financial Measure.

Excluding certain non- recurring items, operating net income* was $44.9 million. ■ Net interest income was $122.4 million in the fourth quarter, an increase of $19.7 million, primarily due to increased average earning assets as a result of the Century merger and higher SBA PPP fee accretion. ■ Noninterest expense was $143.6 million and $110.3 million on an operating* basis primarily due to expenses associated with the Century merger totaling $30.7 million. ■ Release of allowance for loan losses of $4.3 million for the fourth quarter. ■ A tax benefit of $2.9 million was recorded in the fourth quarter, compared to expense of $11.3 million in the prior quarter. $ in millions, except per share amounts Q4 2021 Q3 2021 Q2 2021 Q1 2021 Q4 2020 Net interest income $ 122.4 $ 102.7 $ 104.6 $ 100.1 $ 103.6 Noninterest income 49.0 43.2 45.7 55.2 49.6 Total revenue 171.4 145.9 150.3 155.3 153.2 Noninterest expense 143.6 99.0 107.3 94.0 199.2 Pre-tax, pre-provision income (loss) 27.8 46.9 43.0 61.3 (45.9) (Release of) provision for loan losses (4.3) (1.5) (3.3) (0.6) 0.9 Pre-tax income (loss) 32.2 48.4 46.3 61.8 (46.8) Income tax (benefit) expense (2.9) 11.3 11.5 14.1 (2.7) Net income (loss) $ 35.1 $ 37.1 $ 34.8 $ 47.7 $ (44.1) Operating net income* $ 44.9 $ 37.4 $ 37.1 $ 46.5 $ 31.6 EPS $ 0.20 $ 0.22 $ 0.20 $ 0.28 $ (0.26) Operating EPS* $ 0.26 $ 0.22 $ 0.22 $ 0.27 $ 0.18 ROA1 0.67 % 0.84 % 0.83 % 1.19 % (1.11) % Operating ROA*1 0.86 % 0.86 % 0.89 % 1.15 % 0.79 % Efficiency ratio 83.76 % 67.83 % 71.39 % 60.56 % 129.97 % Operating efficiency ratio* 65.21 % 66.14 % 67.78 % 60.22 % 68.33 % *Non-GAAP Financial Measure.
