Guaranty Bancshares in Addison, Texas, is in a buyer’s frame of mind. The Lone Star State is rife with merger-and-acquisition talk “and we are in those discussions,” Guaranty Chairman and CEO Ty Abston said Monday on a conference call with investment analysts. While $2.9 billion-asset Guaranty “is going to be pretty selective with how we approach” potential deals, the company is interested in banks with $200 million to $600 million of assets that do business in its Central and East Texas footprint, Abston said. “We’ve had lots of conversations,” Abston added. “Let’s see if that develops into an actual transaction.”
