Overbrook, Kansas-based First Security Bank will acquire Conway Bank, a Kansas-based bank, creating a combined company with assets exceeding $225 million.

First Security Bank and its holding company, Overbrook Bankshares, Inc., announced it would be merging with Conway Bank and its holding company, Norcon Financial Corp. As part of the deal, Conway Bank will be merged into First Security, according to a release.

The translation deal is expected to close in the first half of 2026.

Following the merger, the combined bank will have approximately $225 million in total assets with eight locations across the Kansas City, Topeka and Wichita metropolitan areas. The deal will effectively double the size of First Security Bank.

Headquartered in Conway Springs, Conway Bank manages $125 million in total assets across four branch offices throughout Kansas, including Conway Springs, Norwich, Wichita and Argonia. First Security currently operates over $100 million in assets across four locations.

“We’re combining the strengths of two well-respected organizations to create new opportunities for our customers, employees, and the communities we serve,” President & CEO of Conway Bank Joe Rottinghaus said in the release. “Partnering with The First Security Bank allows us to continue the legacy of local decision making, relationship banking and commitment to community while providing greater access to products and services.”
