The lender’s last purchase, of CNB Bank Shares, closed in March and expanded HBT in the St. Louis metropolitan area. Buying Mendota, Illinois-based Tri-County, by contrast, will grow the bank on the outer reaches of the Chicago metro area. Under the deal, Tri-County shareholders will receive either 2.4589 shares of HBT common stock, or $71.01 in cash — or a combination of both — for each Tri-County share they own. Five First State Bank branches, however, stand within two miles of an existing Heartland Bank and Trust office, according to an investor presentation. HBT CFO Peter Chapman told American Banker the bank would “consolidate branches in close proximity where it's logical to do so.”
