Frontier Credit Union has announced an agreement to acquire First Citizens Bank of Butte, marking the credit union’s first expansion into the state of Montana. This strategic move represents more than geographic growth—it reflects Frontier’s continued commitment to delivering community-focused, member-first financial services in new and meaningful ways.
Headquartered in Idaho Falls, Frontier Credit Union has a proud 90-year history of serving its members with personalized care, competitive products, and innovative financial solutions. The acquisition will bring that legacy to Butte, Montana, and provide customers of First Citizens Bank with access to Frontier’s full suite of financial services, including advanced digital banking tools, quick online loan applications, and expanded product offerings.
For Frontier CEO Dan Thurman, a Montana native, the expansion carries personal significance.
“Having grown up in Dillon, it’s a dream having this chance to share Frontier with my home state,” said Thurman. “We’re not just expanding our footprint—we’re extending our mission of helping people build better lives. We can’t wait to be a part of the fabric here in Butte and serve this great community.”
First Citizens Bank of Butte has long served its local customers with dedication and care. That tradition will continue as the organizations transition, with the local branch remaining open and committed to providing the same personalized service. Customers will continue working with the teams they know and trust throughout the integration.
“This transaction brings tremendous opportunities for our customers and employees,” said Casey Reilly, CEO of First Citizens Bank of Butte. “It’s a natural fit—I’m excited our customers will be in the hands of someone who knows what makes Montana special. They know our community, share our values, and appreciate the uniqueness of Butte.”
The proposed acquisition is subject to regulatory approval and shareholder consent. Until the transaction is finalized, both Frontier Credit Union and First Citizens Bank of Butte will continue to operate independently.
This milestone marks an exciting chapter for Frontier Credit Union and the Butte community alike—one rooted in shared values, local investment, and a continued commitment to serving people first.
