We believe this transaction will offer customers and employees of both banks even greater strength and resources while maintaining our commitments to the communities in which we serve.”

“This partnership will greatly benefit our customers and our communities. We expect the shareholders of Athens will benefit from the combined companies’ strong financial performance and growth opportunities going forward,” said Athens President and Chief Executive Officer Jeffrey L. Cunningham. “This is a great partnership – two companies with the same shared values and goals. We are excited.”

“We are proud of what we have accomplished at Athens Federal and we look forward to working with our friends at CapStar for the benefit of all our stakeholders and communities,” said Athens Chairman Larry D. Wallace.
