~ Company Announces a 10% Increase to Quarterly Dividend ~

Eastern Bankshares, Inc. (the “Company,” or together with its subsidiaries, “Eastern”) (NASDAQ Global Select Market: EBC), the stock holding company of Eastern Bank, today announced its 2023 third quarter financial results and the declaration of a quarterly cash dividend of $0.11 per share, representing a $0.01, or 10%, increase from the most recent quarterly dividend.

The release of the Company’s quarterly financial results follows its September 19, 2023 announcement of the sale of the insurance operations of Eastern Insurance Group, LLC (“Eastern Insurance”) (“the insurance transaction”) and the pending merger with Cambridge Bancorp (“Cambridge”) (“the merger”). Proceeds from the insurance transaction will allow Eastern to focus on the growth and strategic initiatives of its core banking business, including the merger with Cambridge. The merger will create a combined franchise with approximately $27 billion in total assets, create the largest bank-owned independent investment advisor in Massachusetts, and further solidify Eastern as the largest Boston-based mid-sized bank by deposits. On a combined basis, the transactions are financially compelling with expected earnings per share accretion in excess of 20% and an expected 10% improvement to the Company’s efficiency ratio.

“The strategic transactions we announced just last month mark the next step in our journey, and will enhance our Boston franchise, allowing us to better meet the needs of our customers and communities,” said Bob Rivers, Chief Executive Officer and Chair of the Board of Eastern Bankshares, Inc. and Eastern Bank. “We are on track to complete the insurance transaction next week. It’s been a remarkable effort by so many to get to the finish line, and I express my gratitude to Tim Lodge, President and Chief Executive Officer of Eastern Insurance, and his entire team. Regarding the merger with Cambridge, we have submitted all required regulatory merger applications and mobilized internal integration resources at both Eastern and Cambridge. I’m confident that the combined transactions will improve our focus, efficiency and profitability, as well as enhance our liquidity position as we continue to operate in a challenging environment.”

• Net income of $59.1 million, or $0.36 per diluted share, compared to net income of $48.7 million, or $0.30 per diluted share, for the prior quarter.
• Operating net income*, which excludes the revenues, expenses, and tax provision of discontinued operations, of $52.1 million, or $0.32 per diluted share, compared to $41.1 million, or $0.25 per diluted share, for the prior quarter.
• The insurance transaction triggered the elimination of a $14.6 million tax valuation allowance that was established as part of the sale of available-for-sale securities in the first quarter of 2023 (the “securities sale”).
• The net interest margin on a fully tax equivalent basis held relatively steady at 2.77% as compared to 2.80% in the prior quarter.

• Healthy balance sheet with 11.6% shareholders’ equity to assets, 8.7% tangible shareholders’ equity to tangible assets* and 16.0% common equity tier 1 capital ratio¹. Borrowings and brokered deposits totaled 5.2% of assets.

Regarding the Company’s third quarter financial results, Mr. Rivers commented, “Our results continue to demonstrate our robust capital position and the strength of our franchise.

In September 2023, following the approval of the insurance transaction by the Company's Board of Directors and in accordance with applicable accounting rules, the Company classified its insurance operations as both held-for-sale and discontinued operations. Accordingly, the Consolidated Balance Sheets and Statements of Income present discontinued operations for the current period and were adjusted for prior periods on a retrospective basis.

1</sup> Regulatory capital ratios are preliminary estimates.

BALANCE SHEET

Total assets were $21.1 billion at September 30, 2023, representing a decrease of $437.2 million, or 2%, from June 30, 2023.

• Total securities decreased $267.9 million, or 5%, from the prior quarter, to $4.7 billion, due to a decrease in the market value of available-for-sale securities as well as principal runoff.
• Total loans were $13.9 billion, representing a decrease of $42.6 million, or 0.3%, from the prior quarter. The decrease was driven primarily by the sale of approximately $192 million of Shared National Credit (“SNC”) loans from the commercial and industrial loan portfolio. This was partially offset by loan originations to core customers.
• Deposits totaled $17.4 billion, representing a decrease of $756.8 million, or 4%, from the prior quarter caused primarily by a decrease in municipal deposits of approximately $375.0 million due in part to seasonality, as well as a decrease in brokered deposits of $305.9 million.
• Borrowed funds increased $364.2 million from the prior quarter to $715.4 million in the third quarter, as Federal Home Loan Bank (“FHLB”) borrowings were used to replace certain maturing brokered CDs.
• Shareholders’ equity was $2.4 billion, representing a decrease of $80.2 million from the prior quarter driven primarily by a decrease in accumulated other comprehensive income, partially offset by retained earnings. Please refer to Appendix D to this press release for a roll-forward of tangible shareholders’ equity*.

Net interest income was $137.2 million for the third quarter of 2023, compared to $141.6 million in the prior quarter, representing a decrease of $4.4 million.

• Net interest margin on a fully tax equivalent (“FTE”) basis* was 2.77% for the third quarter, representing a 3 basis point decrease from the second quarter, as higher funding costs more than offset increases in asset yields.
• Total interest-earning asset yields increased 10 basis points from the prior quarter to 4.05%, due to increased loan and short-term investment yields as a result of higher interest rates during the quarter.
• Total interest-bearing liabilities cost increased 20 basis points from the prior quarter to 1.99%, due primarily to higher deposit costs resulting from deposit pricing increases and deposit mix shifts.

NONINTEREST INCOME

Noninterest income, which excludes revenues from discontinued operations, was $19.2 million for the third quarter of 2023, compared to $26.2 million for the prior quarter, representing a decrease of $7.0 million.

• Debit card processing fees decreased $0.1 million from the prior quarter to $3.4 million.
• Loan-level interest rate swap income increased $0.9 million from the prior quarter to $1.7 million. The increase was driven by higher cash income due to higher customer swap transaction volume and an increase in the fair value adjustment of such transactions.
• Losses from investments held in rabbi trust accounts were $1.5 million in the third quarter compared to gains of $3.0 million in the prior quarter due to investment performance.
• In the third quarter, the Company incurred losses on sales of commercial and industrial loans totaling $2.7 million due to the sale of SNC loans. There were no sales in the prior quarter. The losses on sale were partially offset by the release of loan loss reserves totaling approximately $2.0 million associated with the sale of SNC loans.

NONINTEREST EXPENSE

Noninterest expense, which excludes expenses from discontinued operations, was $101.7 million for the third quarter of 2023, compared to $99.9 million in the prior quarter, representing an increase of $1.8 million. Noninterest expense on an operating basis* for the third quarter of 2023 was $98.7 million, compared to $98.6 million in the prior quarter, an increase of $0.1 million.

• Office occupancy and equipment expense was $8.6 million in the third quarter, a decrease of $0.4 million from the prior quarter.
• Data processing expense was $13.4 million in the third quarter, an increase of $0.6 million from the prior quarter.

Please refer to Appendix G for additional information on discontinued operations.

INCOME TAXES

The income tax benefit for the third quarter was $16.2 million compared to income tax expense of $15.9 million in the prior quarter, a decrease of $32.1 million.

• The insurance transaction triggered the elimination of a $14.6 million tax valuation allowance that was established as part of the securities sale in the first quarter of 2023. The elimination was made following the determination that the capital gain from the insurance transaction and the capital gain carrybacks would be greater than the previously incurred capital loss associated with the securities sale.
• Excluding the impact of the tax valuation allowance elimination, the tax benefit for the third quarter is reflective of Eastern’s year-to-date net pre-tax loss position without consideration for any pre-tax gains resulting from the insurance transaction in the fourth quarter.

ASSET QUALITY

The allowance for loan losses was $155.1 million at September 30, 2023, or 1.12% of total loans, compared to $148.0 million, or 1.06% of total loans, at June 30, 2023. The Company recorded a provision for loan losses totaling $7.3 million in the third quarter of 2023 driven primarily by an increase in specific reserves associated with three commercial real estate loans collateralized by investor office real estate located in Boston’s financial district.

Non-performing loans totaled $47.5 million at September 30, 2023 compared to $30.6 million at the end of the prior quarter. The increase was driven by the non-accrual designation of the three aforementioned commercial real estate loans. During the third quarter of 2023, the Company recorded total net charge-offs of $0.1 million, or less than 0.01% of average total loans on an annualized basis, compared to $0.5 million or less than 0.01% of average total loans in the prior quarter, respectively.

NON-GAAP FINANCIAL MEASURES

*Denotes a non-GAAP financial measure used in this press release.

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 business as well as underlying trends that may, to some extent, be obscured by inclusion of such items in the corresponding GAAP financial measures. Except as otherwise indicated, these non-GAAP financial measures presented in this press release exclude discontinued operations. Please refer to Appendix G to this press release for further information regarding discontinued operations.

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, operating return on average tangible shareholders’ equity (discussed further below), and the operating efficiency ratio. 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) other real estate owned (“OREO”) gains, (vii) merger and acquisition expenses, (viii) the non-cash pension settlement charge recognized related to the Defined Benefit Plan, (ix) certain discrete tax items, and (x) net income from discontinued operations. 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 tangible assets, tangible shareholders’ equity, average tangible shareholders’ equity, tangible book value per share, the ratio of tangible shareholders’ equity to tangible assets including the impact of mark-to-market adjustments on held-to-maturity securities, return on average tangible shareholders’ equity, and operating return on average shareholders’ equity (discussed further above), 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 press release 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 reconciliations of the Company's GAAP financial measures to the non-GAAP financial measures in this press release.
