What is Brief History of Bar Harbor Bankshares Company?

How did Bar Harbor Bankshares grow from a local island bank to a regional leader?

Founded in 1887 in Bar Harbor, Maine, the bank began as a community lender serving year-round residents and summer visitors. A transformative $143 million acquisition in 2017 expanded its footprint across Maine, New Hampshire, and Vermont. By Q3 2025 it reports about $4.2 billion in assets.

Bar Harbor retained local decision-making while adding commercial lending and wealth management, keeping a Tier 1 leverage ratio near 9.5%. Read the Bar Harbor Bankshares Porter's Five Forces Analysis for strategic context.

Founded October 18, 1887, Bar Harbor Bankshares began as Bar Harbor Banking and Trust Company to serve Mount Desert Island’s growing seasonal economy; local leaders created a bank combining commercial deposits with trust services to support sizeable property and estate needs.

Founding Story of Bar Harbor Bankshares

The bank was chartered on October 18, 1887, with an initial capital stock of $50,000, backed by prominent local businessmen and civic leaders including Luere B. Deasy.

• The founders identified a gap: Mount Desert Island lacked a permanent institution for large property transactions during the Gilded Age.
• Early business model blended commercial banking and trust services, positioning it as a regional fiduciary pioneer.
• The board combined legal expertise and local commerce experience to transition the island’s economy from barter to capital-driven services.
• The bank’s vault survived the Great Fire of 1947, becoming a cornerstone in the town’s reconstruction and local economic resilience.

The Bar Harbor Bankshares company profile reflects a conservative fiscal philosophy rooted in its founding, with early emphasis on maritime and tourism industries that shaped its evolution and long-term growth.

2016–2019 Strategic Shift

Under President and CEO Curtis Simard the 2017 purchase of Lake Sunapee Bank and the 2019 acquisition of eight People's United Bank branches produced a regional footprint exceeding 50 branches across three states.

The Lake Sunapee deal pivoted the bank from a Maine-centric institution toward regional scale; the 2019 branch purchase added approximately $287 million in deposits, accelerating the Bar Harbor Bankshares historical performance.
