Total deposits increased by 58.3% to $15.80 billion as of June 30, 2025, compared to $9.98 billion as of December 31, 2024, in connection with the CrossFirst acquisition. Busey focuses on deepening its customer relationships to maintain and protect its strong core deposit 3 franchise. Core deposits include non-brokered transaction accounts, money market and savings deposit accounts, and time deposits of $250,000 or less. Core deposits represented 92.5% of total deposits as of June 30, 2025.
