BRUNSWICK — With more than 2,100 ballots cast, the members of York County Federal Credit Union have agreed to merge with Atlantic Federal Credit Union.

The vote showed 86 percent of York County members saying yes to the merger.

Atlantic currently serves the communities of Brunswick, Topsham, Freeport, and Cumberland, but when the merger becomes official, Atlantic branches will also include Saco, Biddeford, Sanford, South Sanford, and York.

Two additional steps are required to make the merger official. Final authorization from the National Credit Union Administration is expected to be completed by the end of March and the operating systems of both credit unions will then be unified by June 3.

“We are very excited by the support from the York County members. We have always believed that our two successful Credit Unions would be stronger together,” said Atlantic CEO/President, Roger Sirois and York County CEO/President Scott Chretien in a joint statement. “It is about continuing to provide our members with the latest in technology and help them do better. Atlantic and our members have a fantastic future ahead of us.”

After final approval from the NCUA, Chretien will assume the role of CEO and Roger Sirois will be president of Atlantic.

Atlantic Federal Credit Union will be the largest credit union in the state of Maine, with more than $712 million in assets and over 47,000 members who live, work and/or worship in Cumberland, Sagadahoc, and York counties.
