Hancock Holding Company Completes Whitney Holding Corporation Merger

Hancock Holding Company (Nasdaq:HBHC) ("Hancock") announced today the completion of its acquisition of Whitney Holding Corporation (Nasdaq:WTNY) ("Whitney"), effective Saturday, June 4, 2011.

"This milestone in the rich histories of two well-established Gulf South banks begins a new era of opportunity for the company, our Hancock and Whitney customers, and the communities we serve," said Hancock Holding Company President and Chief Executive Officer Carl J. Chaney. "The merger of Whitney into Hancock joins two longtime neighbors committed for more than a century to values of strength, stability, integrity, and service."

Subject to the terms of the merger agreement, Whitney shareholders are entitled to receive 0.418 shares of Hancock common stock in exchange for each share of Whitney common stock they owned immediately prior to the merger. 

As a result of the merger, Hancock Holding Company is now the parent company of two banks: Hancock Bank, headquartered in Gulfport, and Whitney Bank, headquartered in New Orleans and the largest state-chartered bank in Louisiana. Chaney and fellow Hancock CEO and Chief Operating Officer John M. Hairston will continue to lead Hancock Holding Company and remain as senior executives of Hancock Bank, while veteran New Orleans and Whitney banker Joseph S. "Joe" Exnicios has been appointed president of Whitney Bank.

"This combination creates the preeminent Gulf South financial institution, with $20 billion in assets and nearly 300 full-service branch locations. We believe the complementary strengths of Hancock and Whitney create a superior, dynamic financial institution with experienced local leadership and talented associates who are ready to serve our valued customers and communities throughout our business footprint spanning the Gulf Coast from Houston, Texas, to Tampa, Florida," Chaney emphasized.

Until Hancock Bank and Whitney Bank convert to a single operating system—anticipated to occur in early 2012, Hancock and Whitney customers should continue to do business at their current Hancock or Whitney branches. However, customers of both banks can now use Hancock and Whitney ATMs free of charge.

"It's business as usual at all Hancock and Whitney branches, with the immediate benefit of access to nearly 400 ATMs across five states for customers of both banks," added Chaney.
