SEACOAST BANK COMPLETES ACQUISITION OF BMO HARRIS’ ORLANDO BANKING OPERATIONS

STUART, Florida, (June 6, 2016) – Seacoast Banking Corporation of Florida (“Seacoast”) (NASDAQ: SBCF), the holding company for Seacoast National Bank (“Seacoast Bank”), announced today that it has completed the acquisition of the Orlando banking operations of BMO Harris Bank, N.A. (“BMO”), including BMO’s 14 Orlando branches. The acquisition includes all of BMO’s retail branches and the associated consumer and small business deposit accounts as well as BMO’s business banking deposit and loan accounts in the Orlando MSA, and adds approximately $314 million in deposits and approximately $64 million in loans.

“We are delighted to welcome BMO’s more than 8,000 households to Seacoast Bank,” said Dennis S. Hudson, Chairman and CEO of Seacoast.  “Seacoast opened its first branches in the Orlando MSA in 2005. We continued our expansion in 2014 through the acquisition of Winter Park-based BankFirst and the acquisition of Lake Mary-based Floridian Financial Group, Inc. earlier this year. The acquisition of BMO’s offices solidifies our position in the attractive Orlando market, making Seacoast Bank a top-10 Orlando bank and the largest Florida-based bank in that market.”
