Cambridge Bancorp and Optima Bank & Trust Company to Merge

Company Release - 12/5/2018 6:10 PM ET

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Cambridge Bancorp (Nasdaq: CATC) (the “Company” or “Cambridge”), the holding company for Cambridge Trust Company (“Cambridge Trust”), and Portsmouth New Hampshire-based Optima Bank & Trust Company (“Optima”), are pleased to jointly announce that Cambridge, Cambridge Trust and Optima have entered into a definitive agreement pursuant to which Optima will merge with and into Cambridge Trust in a stock and cash transaction. Under the terms of the agreement, each share of Optima common stock will be exchanged for either 0.3468 shares of Cambridge common stock, or $32.00 in cash, subject to customary pro-ration procedures which will result in an aggregate stock / cash consideration mix of 95% / 5%. The transaction is presently valued at approximately $67 million in the aggregate, based upon Cambridge Bancorp’s closing price of $85.61 as of December 4, 2018. On a pro forma basis, the transaction is expected to be approximately 3.6% accretive to Cambridge’s 2020 earnings per share and approximately 3.8% dilutive to tangible book value per share with an earnback period of approximately 3.4 years.

While Cambridge Trust has provided wealth management services in the New Hampshire community since the 1990’s, it has lacked comprehensive banking services. This combination will enhance and expand Cambridge’s southern New Hampshire presence with the addition of six full service branch locations to complement Cambridge’s three existing wealth management offices in the state. Cambridge currently manages $1.1 billion of wealth assets for New Hampshire-based clients, and this merger will enable the combined company to provide both locally-based banking and wealth solutions in southern New Hampshire.

As of September 30, 2018 Optima had approximately $524 million of total assets, $466 million of loans and $489 million of deposits. Based on financials as of September 30, 2018, the combined company will have over $2.5 billion in assets, $1.9 billion in gross loans, $2.2 billion in deposits, and $3.2 billion of wealth management assets upon completion of the transaction.

“Our merger with Optima Bank is a natural fit and consistent with our growth strategy to become the premier private bank and wealth management company throughout Greater Boston and Southern New Hampshire,” said Denis Sheahan CEO of Cambridge Trust. “By joining forces, we’ll be able to provide our wealth management clients in New Hampshire with access to a full suite of private banking services and convenient office locations, while clients of Optima Bank will benefit from Cambridge Trust’s comprehensive investment management, wealth planning, and trust services.”

Daniel Morrison, Chairman, President and CEO of Optima, and other key members of the Optima team will remain with Cambridge to help drive the combined company’s future growth in southern New Hampshire.

“Through the combined organization, we will be well-positioned to offer differentiated, high-touch private banking and wealth management services to clients and prospects in Southern New Hampshire,” said Mr. Morrison. “Cambridge Trust has been in our market since 1996 and has amassed over $1 billion in New Hampshire-based wealth management assets. I look forward to working with the Cambridge Trust team to accelerate our combined growth in New Hampshire."

The transaction has been approved by the Boards of Directors of both companies and is expected to be completed during the second quarter of 2019, subject to regulatory approval, approval by Optima’s shareholders, and other customary closing conditions. Effective at the closing of the transaction, Mr. Morrison will join the Board of Directors of both Cambridge Bancorp and Cambridge Trust Company.
