“The completion of this merger marks a significant milestone for our clients, associates,
shareholders and communities,” said Bryan Jordan, president and CEO of First Horizon. “The
combined company’s enhanced scale, diversified business model and expertise in financial
services uniquely position us to better serve our clients and communities, accelerate our growth
and create long-term shareholder value.”

extraordinary combination reflects hard work, dedication and collaboration across the platforms
as we work to build a premier southern-based bank. With the incredible legacies of both
organizations as our foundation, we plan to combine the best of both companies to position us
for success in this rapidly evolving world.

“Clients can count on us to keep them informed and prepared. Ensuring
that the transition and conversion are as seamless as possible is a top priority.”

Clients will continue to be served through their respective First Horizon or Iberia Bank branches, websites, mobile apps, financial advisors and relationship managers until systems are
integrated. Iberia Bank will adopt the First Horizon name following operating systems
conversion, which is expected to occur in mid-2021. For convenience, clients can continue to use
