December Page 2 11, 2023 Page 2 FirstName LastName Unaudited Pro Forma Condensed Combined Financial Information 3. Pro Forma Adjustments to the Unaudited Condensed Combined Balance Sheets, page 41 4. It appears that anticipated restructuring expenses described in adjustments A and F represent Management's Adjustments that, if needed, should only be presented in the explanatory notes in the form of a reconciliation. Please revise as appropriate or tell us why you believe they represent Transaction Accounting Adjustments. Please revise corresponding adjustment F in the statement of income as needed. Refer to Rule 11- 02(a)(7) for guidance. Background of the Merger, page 55 5. We note your discussion on page 56 that Messrs. Rivers and Sheahan had "discussed the potential strategic benefits of a business combination" prior to the first quarter of 2023 but that a potential business combination "was not sufficiently compelling." We also note your reference to other potential transaction partners, such as in the second paragraph on page 59. Please revise to clarify the reasons why Messrs. Rivers and Sheahan determined that a business combination had become compelling in the first quarter of 2023. For example, it is unclear to what extent Eastern's exploration of a sale of Eastern Insurance in late May led to Mr. Rivers initiating the conversation about a business combination with Mr. Sheahan on June 7. Similarly it is unclear to what extent Eastern's "balance sheet repositioning" during the first quarter of 2023 related to the decision to reconsider a business combination with Cambridge. Additionally, explain in more detail whether and, if not why not, other potential business combination parties were considered. 6. Please revise and expand your background discussion to identify the key negotiation considerations as well as how and why material terms were revised over time. For example, we note that: During the June 7, 2023 meeting, Mr. Rivers and Mr. Sheahan discussed the executive leaders of Cambridge's wealth management unit and private banking division; however, you do not describe any discussions related to continued employment or involvement of such persons post-business combination; On page 59 you refer to "preliminary pro forma analysis," but you do not explain or quantify it; In the second full paragraph on page 59, you refer to "an update on their preliminary analysis of the financial impact of the potential transaction," but you do not explain or quantify it; In the same paragraph you refer to "key open issues," but you do not identify any key issues other than whether the draft merger agreement would include the sale of Eastern Insurance as a condition; and In the second to last paragraph on page 60, you refer to market conditions and "the relative trading prices" of the companies' common stock as reasons for changes to the exchange ratio, but you do not explain the market conditions, relative prices or changes to the prices. Robert F. Rivers Eastern Bankshares, Inc. December 11, 2023 Page 3 7. Please provide a brief description of the material discussions or actions that took place during the July 26, 2023 meeting. Please also describe the "certain assumptions" and "certain strategic and operational benefits," as referenced on page 57. Certain Unaudited Prospective Financial Information Certain Stand-Alone Eastern Prospective Financial Information used by BofA Securities, page 87 8.

If the projections are not in line with historic operating trends, please advise us why the change in trends is appropriate or assumptions are reasonable.
