A merger between Horizon Credit Union and Montana First Credit Union has been approved by both credit unions’ boards.

The deal should be closed by the end of the year and give the credit unions extended reach across three states.

Horizon has 38,000 members, 16 branches and assets of $420 million.

Montana First is based in Missoula with two branches, 7,900 members and $60 million in assets. It was established 80 years ago to serve Forest Service employees.
