First Busey Corporation is a financial holding company headquartered in Leawood, Kansas, with roughly $18B in total assets. Its core subsidiary, Busey Bank, is an Illinois state-chartered bank founded in 1868 that operates 79 banking centers across 10 states, with the majority concentrated in Illinois. Busey Bank serves consumers and businesses with a standard range of commercial and retail banking products, including commercial loans, CRE loans, residential real estate, home equity lines, and deposit accounts. Beyond core banking, Busey runs two notable businesses: a wealth management operation that provides investment management, trust and estate, financial planning, and tax services with $15.66B in assets under care; and FirsTech, a payment processing subsidiary serving regulated industries like utilities, insurance, and telecom. Busey earns primarily through net interest income, which accounted for roughly 79% of total revenue in 2025, driven by the size of its loan and investment portfolio and its net interest margin. The remaining roughly 21% of revenue comes from wealth management fees, service charges, and FirsTech payment technology revenue. Busey has grown largely through acquisitions, completing roughly 10 bank deals since 2015. The most significant was the March 2025 acquisition of CrossFirst Bankshares, which roughly doubled Busey's asset base from ~$12B to ~$18B and expanded its footprint across 10 states. Busey organizes its operations into five geographic regions and several industry verticals, including Sponsor Finance, Energy Lending, and SBA Lending.
