July 14, 2026
Rhineland, Missouri – PSB Bank announced the successful completion of its operational merger with Bank Star on July 11, 2026, with PSB Bank serving as the surviving institution. The conversion represents the final phase of the acquisition and integration process, creating a combined community banking organization with more than $1 billion in assets and an expanded footprint across Missouri.
The merger combines two long-standing community banking franchises with complementary markets, experienced banking teams, and a shared commitment to relationship banking. Customers transitioned to the PSB Bank operating platform over the weekend with minimal disruption following months of planning, system testing, and coordinated execution by employees from both organizations.
The completed integration strengthens PSB Bank’s market presence while enhancing its ability to provide expanded commercial, agricultural, mortgage, consumer, and treasury management services to customers throughout its growing service area.
“This merger represents an important milestone in our long-term growth strategy,” said Mark Laune, President and Chief Executive Officer of PSB Bank. “By bringing together the strengths of PSB Bank and Bank Star, we have created a stronger community bank that combines local decision-making with greater financial capacity and expanded capabilities. Reaching the billion-dollar asset threshold positions us to continue investing in technology, our employees, and the communities we proudly serve while maintaining the personalized service that defines community banking.”
Laune also recognized the significant efforts behind the successful integration.
“The successful conversion reflects the extraordinary work of employees from both organizations. Their commitment, professionalism, and unwavering focus on our customers made this transition seamless. We are excited to welcome Bank Star customers and employees to the PSB Bank family and look forward to building on the strong relationships both organizations have established over many decades. Together, we are positioned to write the next chapter of community banking excellence.”
The merger reinforces PSB Bank’s strategic focus on sustainable growth while preserving the local leadership and customer-first philosophy that have long distinguished both institutions. As a billion-dollar community bank, PSB Bank is well positioned to meet the evolving financial needs of individuals, businesses, agricultural producers, and municipalities throughout the region while continuing to make lending decisions locally and invest in the communities it serves.
