Simmons First National Corp. will donate a branch to Arkadelphia, Arkansas-based Southern Bancorp upon finalizing its acquisition of Delta Trust & Bank. The branch transfer allows Simmons First to adhere to federal regulations limiting acquisitions in places where banks already hold significant market share while also supporting Southern's community development work. “Our focus is specifically on rural communities just like Eudora, which means we are aware of both the challenges they face and the opportunities that exist," Southern Bancorp Inc. CEO Darrin Williams said.
