GLENS FALLS, N.Y., July 1, 2026 /PRNewswire/ -- Arrow Financial Corporation (NASDAQ:AROW) ("Arrow" or "AROW"), the parent company of Arrow Bank National Association, today announced the completion of the previously announced strategic acquisition of Adirondack Bancorp, Inc. ("Adirondack") and its banking subsidiary Adirondack Bank, which was merged with and into Arrow Bank.

The combined company has approximately $5.4 billion in total assets, $4.8 billion in total deposits and $4.1 billion in gross loans (based on financial information as of March 31, 2026). This strategic acquisition extends Arrow Bank's footprint to 57 branches across northeastern New York and into the Mohawk Valley to include Oneida, Herkimer and Franklin counties, while strengthening its commitment to Essex and Clinton counties.

David S. DeMarco, Arrow President and CEO, stated, "Today we proudly welcome Adirondack customers, employees and communities to the Arrow Family of Companies. This strategic acquisition brings together two highly complementary community banks with shared values, strong local roots and a commitment to helping individuals, businesses and communities thrive. Together, we are well-positioned to deliver expanded products, services and expertise while maintaining the personalized, community-focused approach that has defined our banks for generations. As Arrow celebrates its 175^th anniversary, this milestone reflects our commitment to thoughtful growth expanding our market presence and creating long-term value."

In connection with the closing of the merger, Rocco F. Arcuri Sr., the former President and CEO of Adirondack, has become Senior Vice President, Regional President, Mohawk Valley of Arrow, and was appointed to the Arrow Board of Directors.

Arcuri stated, "This marks the beginning of an exciting new chapter for our clients, employees and communities. I am proud to continue serving this market as Regional President and look forward to helping our clients benefit from the products, services and expanded resources that Arrow Bank provides while maintaining the local relationships they value most."

Integration teams will work closely together in the months ahead to ensure a seamless transition. Customers can continue to expect the same personal relationship-based service and local expertise they value today, with additional enhancements and expanded offerings becoming available as integration efforts progress. Beginning July 1, customers will begin to see Arrow Bank branding at Adirondack branch locations and in customer communications. Until the conversion and integration of banking systems to Arrow Bank's platform later in 2026, customers may continue to see the Adirondack Bank name and logo on certain documents, statements, checks, cards and digital banking platforms during the transition period. Any references to Adirondack Bank after July 1 should be understood to mean Arrow Bank.
