A Bank for Maine’s Future: Camden National and The Bank of Maine merge to create the strongest and most innovative community bank headquartered in the state of Maine

We are excited to announce that Camden National Corporation, the parent company of Camden National Bank, and SBM Financial, Inc., the parent company of The Bank of Maine, have signed a definitive agreement to merge organizations, which will create Maine’s largest independent community bank headquartered in the State with $3.6 billion in assets. The combined organization will operate under the Camden National Bank name and brand and will be led by Gregory A. Dufour, president and chief executive officer of Camden National Corporation and Camden National Bank. It will be headquartered in Camden, Maine with several leadership positions in Portland.

We are pleased to welcome The Bank of Maine employees and customers to Camden National. The union of these two great organizations will redefine what it means to be a community bank. Together, we have a combined history of over 320 years of providing local service to the people of Maine. As the largest community bank in Maine, we are poised to continue to provide our customers and shareholders with an enduring value. We are a financially strong institution that is a leader in Maine’s financial services industry and is Maine’s bank for the future. Our focus will remain on expanding relationships with customers and providing them the products and services to meet their needs such as premier digital banking tools, a wide range of lending and deposit options, as well as wealth management and investment services. Camden National will also be able to help even more communities thrive with programs such as Hope@Home, our homelessness awareness initiative.”

Over the past several years, we have worked as a team to re-shape ourselves for the future, through branch acquisitions and divestures while growing organically and providing a lasting value for our customers and shareholders. The Bank of Maine not only shares many of our same values, but also has corporate offices in Portland’s vibrant downtown and branches in the Southern Maine surrounding communities.

The Bank of Maine has been reenergized over the past five years under the leadership of John Everets and his management team. Many of their strategies align with our own strategic plans and vision for our organization. Their culture, best shown how by their tagline “Honesty first,” aligns with our first Core Value, “Honesty and Integrity, above all else.”

Transition timeline

Over the next several weeks and months, teams from Camden National and The Bank of Maine will work together to gain the many approvals a change of this magnitude requires, ranging from shareholders to regulators. We will also work together to create a transition plan that will not only transform our organizations, but transform community banking in the state of Maine.

What does this mean to you as a stakeholder?

As we await final regulatory and shareholder approvals, it is business as usual.  As always, our focus remains on serving our customers, each and every day, and that priority will continue throughout this transition. While there’s already been a dedicated group of stakeholders working diligently behind the scenes on this project, we’ll need even more stakeholder participation and assistance in the weeks and months ahead.  Please note: As we are bound by legal requirements, we ask that you do not directly reach out to Bank of Maine employees or visit the new branch locations until the transaction has been completed. In addition, please refrain from liking their Facebook page, or looking up profiles on LinkedIn or other social media tools.
