Two Northern California credit unions plan $2 billion merger.
The combination of Sierra Central and First U.S. Community would create a 114,000-member institution with 23 branches across the region.
Sierra Central Credit Union and First U.S. Community Credit Union plan to merge, creating a Northern California credit union with more than $2 billion in assets and 114,000 members, pending regulatory approval and a vote by First U.S. members.
Sierra Central, based in Yuba City, would be the surviving institution. Shonna Shearson, First U.S.’s current chief executive, would lead the combined credit union. Ron Sweeney, Sierra Central’s CEO, plans to retire once the merger is approved and the two institutions become one.
The proposed combination would bring together two credit unions with overlapping footprints across Northern California. Sierra Central has more than $1.5 billion in assets and about 86,000 members, while Sacramento-based First U.S. Community has $545 million in assets and more than 28,000 members.
Together, the credit unions would have more than 300 employees working across 23 branches.
The legal closing, known as LD1, is expected in the first half of 2027, assuming the required approvals are obtained. Operational integration would continue through 2027 and 2028.
The institutions said layoffs are not anticipated, citing a commitment to retaining employees.
“People are key to our success,” Shearson said.
For First U.S., the merger would give its members access to the larger combined organization while putting Shearson in charge of an institution more than twice the size of the credit union she currently leads.

Bringing AI-native deep intelligence to Tyfone’s AI-first solution.
Most credit unions and community banks don’t have an AI strategy yet, and account holders aren’t waiting. They’re already comparing every digital experience, banking included, to ChatGPT. Stand still and get left behind.
Fathom is the AI layer woven throughout Tyfone’s digital banking ecosystem, combining account holder financial data, institutional knowledge, and native banking experiences into a single intelligence layer.
“At First U.S., our purpose has always been to help people build better lives through trusted financial guidance and genuine relationships,” Shearson said. “By bringing together two strong, community-focused credit unions, we’re creating an organization that’s better equipped to serve our members today while preparing for the needs of tomorrow.”
Sweeney described the transaction as a partnership rather than one institution simply absorbing another.
“This is a partnership, both organizations are uniting under a shared vision to better serve our members and communities,” he said. “This merger brings together the talents, expertise, and resources of both organizations.”
Sierra Central has a long history in the region, opening its first branch at Beale Air Force Base in 1955. It now operates 18 branches serving communities across a wide swath of Northern California, including Yuba, Sutter, Butte, Shasta, Sacramento and other counties.
First U.S., founded in 1936, serves members in 12 Northern California counties from its Sacramento headquarters and offers both personal and business financial services.
The merger would add scale to Sierra Central’s existing regional network, while expanding the combined institution’s reach to 23 locations. The credit unions said the larger presence would create opportunities for growth and allow them to offer additional products and services.
The deal is also subject to the cooperative structure of the two institutions. Because they are member-owned credit unions, final approval depends on First U.S. members voting in favor of the merger, in addition to the required regulatory approvals from the National Credit Union Administration.
Both credit unions said they will provide additional information to members through their websites and other communication channels as the process moves forward.
For Sierra Central, the transaction comes as the organization has already grown into one of the larger community-based credit unions serving Northern California. For First U.S., it represents a path into a larger regional institution while keeping its current chief executive in line to lead the combined organization.
The two credit unions expect the legal merger to be completed during the first half of 2027, with the work of combining their operations extending well beyond the closing date.
“By bringing together two strong, community-focused credit unions, we’re creating an organization that’s better equipped to serve our members today while preparing for the needs of tomorrow.”
