As of 30 June 2013, the acquirer had approximately $630m in assets, which will exceed to $800m post transaction and subsequent merger.

Commenting on the acquisition, CrossFirst chairman Ron Baldwin said the Tulsa market was important as it completes the company’s four-market strategy, including Kansas and Oklahoma cities, Wichita, and Tulsa.

"Tulsa National is a well-established bank and has a similar one-location strategy to serve businesses, professionals and their families," Baldwin added.

Founded in 1984, Tulsa National has one branch and $150m in assets, while CrossFirst Bank has $560.6m in assets and one location each in Kansas City, Wichita and Oklahoma City.

Formerly known as CrossPoint Bank, the institution was founded in 2007 by a group of financial executives and business leaders to meet the requirements of business owners, professionals and their families.
