After finalizing its merger with Waltham-based RTN Federal Credit Union on Thursday, Merrimack Valley Credit Union is now one of the state’s five largest credit unions.

The newly merged credit union will operate under the Merrimack Valley Credit Union brand until a new name for the combined institution is launched in late 2024. MVCU now has over $2.3 billion in assets, 115,000 members and 28 branches.

Members of MVCU and RTN voted to approve the merger in March.

“Over the past few months, I have watched my teammates from MVCU and the former RTN work together to make this merger as smooth of a transition as possible for both our members and team members,” MVCU President and CEO John Howard said in a statement. “We are so fortunate to share very similar cultures and values, and working together has been such a wonderful experience. I am so excited to be a part of the team that runs this financial institution and to continue serving our members and community with the amazing service they have come to expect!”

Beginning on June 1, both MVCU members and former RTN members will be able to bank at any MVCU or former RTN branch location and utilize all MVCU and RTN ATMs surcharge-free, MVCU said.
