•

Other income decreased by $488,000, or 50.6%, to $476,000 for the three months ended June 30, 2023, as compared to $964,000 for the three months ended March 31, 2023, primarily due to income associated with success fees of Innovation Banking loans and gains recognized during the quarter ended March 31, 2023 on a community development fund investment, while no such income was recognized during the quarter ended June 30, 2023.

•

Loan related derivative income decreased by $241,000, to a loss of $7,000 for the three months ended June 30, 2023, as compared to $234,000 for the three months ended March 31, 2023, primarily as a result of lower volume of loan related derivative transactions.

Wealth Management Assets under Management and Administration were $4.4 billion at June 30, 2023, an increase of $92.0 million, or 2.2%, from $4.27 billion at March 31, 2023, primarily due to positive returns in both the bond and equity markets.

This change was primarily the result of lower bank owned life insurance (“BOLI”) income, lower wealth management revenue, and lower other income, partially offset by higher deposit account fees. Noninterest income was 24.5% of total revenue for the six months ended June 30, 2023.

•

BOLI income decreased by $1.2 million, or 75.2%, to $379,000 for the six months ended June 30, 2023, as compared to $1.5 million for the six months ended June 30, 2022, primarily due to a gain related to a death benefit claim and a policy surrender that occurred during the six months ended June 30, 2022, while no such benefit claims or policy surrenders occurred during the six months ended June 30, 2023.

•

Wealth management revenue decreased by $683,000, or 4.1%, to $16.0 million for the six months ended June 30, 2023, as compared to $16.7 million for the six months ended June 30, 2022, primarily due to the effect of lower wealth management assets in the first half of 2023 as compared to the comparative period in 2022. Wealth Management Assets under Management and Administration were $4.4 billion at June 30, 2023, an increase of $299.5 million, or 7.4%, from $4.1 billion at December 31, 2022, primarily due to positive returns in both the bond and equity markets.

•

Other income decreased by $354,000, or 19.7%, to $1.4 million for the six months ended June 30, 2023, as compared to $1.8 million for the six months ended June 30, 2022, primarily due to lower income associated with success fees of Innovation Banking loans recognized during the six months ended June 30, 2023 as compared to the six months ended June 30, 2022.

•

Deposit account fees increased by $509,000, or 41.1%, to $1.7 million for the six months ended June 30, 2023, as compared to $1.2 million for the six months ended June 30, 2022, primarily due to increased fee revenue from commercial deposit sweep products as a result of higher interest rates.

During the three months ended June 30, 2023, there was an increase in non-operating expenses and FDIC insurance, partially offset by a decrease in salary and benefits expense and professional fees, as compared to the three months ended March 31, 2023.

•

Non-operating expense increased by $3.1 million, to $3.5 million for the three months ended June 30, 2023, from $424,000 for the three months ended March 31, 2023, primarily due to Northmark Bank (“Northmark”) merger related expenses associated with the systems conversion that occurred during the second quarter of 2023.

•

Salary and employee benefits expense decreased by $1.5 million, or 8.1%, to $17.0 million for the three months ended June 30, 2023, from $18.5 million for the three months ended March 31, 2023, primarily due to lower variable based compensation and lower staffing levels combined with the seasonality of employee benefits expenses.

•

Professional fees decreased by $260,000, or 23.2%, to $863,000 for the three months ended June 30, 2023, from $1.1 million for the three months ended March 31, 2023, primarily due to lower legal fees and employment agency fees.

Total noninterest expense increased by $6.5 million, or 12.5%, to $58.7 million for the six months ended June 30, 2023, as compared to $52.2 million for the six months ended June 30, 2022, primarily driven by an increase in non-operating expenses, salary and benefits expense, and marketing expenses as compared to the six months ended June 30, 2022.

•

Non-operating expense increased by $3.7 million to $3.9 million for the six months ended June 30, 2023, from $246,000 for the six months ended June 30, 2022, primarily due to merger related expenses associated with the Northmark systems conversion.

•

Salary and employee benefits expense increased by $1.0 million, or 3.0%, to $35.5 million for the six months ended June 30, 2023, from $34.4 million for the six months ended June 30, 2022, primarily due to higher overall staffing levels associated with the Northmark merger, normal merit increases, and increases in employee benefit costs.

•

Marketing expense increased by $642,000, or 145.2%, to $1.1 million for the six months ended June 30, 2023, from $442,000 for the six months ended June 30, 2022, primarily due to the timing of marketing spend.

Forward-looking Statements

Certain statements herein may constitute “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Such forward-looking statements about the Company and its industry involve substantial risks and uncertainties. Statements other than statements of current or historical fact, including statements regarding the Company’s future financial condition, results of operations, business plans, liquidity, cash flows, projected costs, and the impact of any laws or regulations applicable to the Company. Words such as “anticipates,” “believes,” “estimates,” “expects,” “forecasts,” “intends,” “plans,” “projects,” “may,” “will,” “should,” and other similar expressions are intended to identify these forward-looking statements. Such statements are subject to factors that could cause actual results to differ materially from anticipated results. Such factors include, but are not limited to, the following: the businesses of Cambridge Bancorp and Northmark may not be combined successfully, or such combination may take longer to accomplish than expected; the cost savings from the merger may not be fully realized or may take longer to realize than expected; operating costs, customer loss and business disruption following the merger, including adverse effects on relationships with employees, may be greater than expected; changes to interest rates; the ability to control costs and expenses; the current global economic uncertainty and economic conditions being less favorable than expected; disruptions to the credit and financial markets; changes in the Company’s accounting policies or in accounting standards; weakness in the real estate market; legislative, regulatory, or accounting changes that adversely affect the Company’s business and/or competitive position; the Dodd-Frank Act’s consumer protection regulations; the impact of the COVID-19 pandemic and actions taken in response to the pandemic on consumer confidence and global and regional economies and economic activity; a prolonged resurgence in the severity of the COVID-19 pandemic due to

variants and mutations of the virus; disruptions in the Company’s ability to access the capital markets; effects of changes in amounts of deposits on the Company’s funding costs and net interest margin; changes in non-performing assets; future provisions for credit losses; and other factors that are described in the Company’s filings with the Securities and Exchange Commission, including the Annual Report on Form 10-K for the year end December 31, 2022, which the Company filed on March 16, 2023. The Company does not undertake, and specifically disclaims any obligation, to publicly release the result of any revisions which may be made to any forward-looking statements to reflect the occurrence of anticipated or unanticipated events or circumstances after the date of such statements. You are cautioned not to place undue reliance on these forward-looking statements.

Non-GAAP Measures

This press release contains financial information determined by methods other than in accordance with GAAP. This information includes operating net income and operating diluted earnings per share, tangible book value per share and the tangible common equity ratio, operating return on average assets, operating return on tangible common equity, and operating efficiency ratio.

Operating net income and operating diluted earnings per share exclude items that management believes are unrelated to its core banking business such as merger and acquisition expenses, gain (loss) on disposition of investment securities, and other items. The Company’s management uses operating net income and operating diluted earnings per share to measure the strength of the Company’s core banking business and to identify trends that may to some extent be obscured by such excluded gains or losses.

Management also supplements its evaluation of financial performance with an analysis of tangible book value per share (which is computed by dividing shareholders’ equity less goodwill and acquisition related 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 acquisition related intangibles), return on average assets and return on tangible common equity on an operating basis, and the operating efficiency ratio (which is computed by dividing noninterest expense adjusted for non-operating expenses and total revenue adjusted for gain/(loss) on disposition of investment securities). The Company has included information on these non-GAAP financial measures because the Company believes that investors may find it useful to have access to the same analytical tool used by management. As a result of merger and acquisition activity, the Company has recognized goodwill and other intangible assets in accordance with generally accepted 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 non-operating 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 are not necessarily comparable to non-GAAP performance measures which may be presented by other companies.

Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are presented under “GAAP to Non-GAAP Reconciliations.”
