EXHIBIT 99.1

First Horizon's Execution Leads to Strong Showing in 2011

MEMPHIS, Tenn., Jan. 20, 2012 (GLOBE NEWSWIRE) -- Fundamentals in First Horizon National Corp.'s (NYSE:FHN) core businesses in the fourth quarter of 2011 continued to be strong, headwinds from the company's legacy businesses continued to diminish and credit trends continued to improve as the company returned to profitability for the year. In 2011 deposit market share, loans and deposits grew in the First Tennessee regional banking business, and the unique business model in the FTN Financial capital markets business continued to make that group a strong contributor.  

"2011 was another year of significant progress for First Horizon, and we're well-positioned to continue that trend this year," said Bryan Jordan, First Horizon chairman and CEO. "We're ready to meet the continuing challenges of a slow economic recovery and a low interest rate environment. The dedicated professionals throughout our company are working hard to deepen relationships with our customers, earn new business and successfully execute our long-term strategic plan."  

Financial results

• Net income available to common shareholders was $34.9 million for the fourth quarter of 2011, compared to $36.1 million in third quarter 2011. Net income available to common shareholders was $131.2 million for all of 2011, compared to a loss of $57.8 million for 2010.   
• Pre-tax income in the core business segments of regional banking, capital markets and corporate grew 28 percent in 2011 compared to 2010. Consolidated pre-tax income improved to $149.8 million in 2011 from $51.8 million in 2010.     
• Diluted earnings per share for the fourth quarter were $0.13, nearly matching the $0.14 EPS from the third quarter of 2011, and diluted EPS for full-year 2011 was $0.50 compared to a loss of $0.25 for 2010.

Segment highlights led by core business strength

• The regional bank generated improvement in core deposits, loans, net interest margin, revenues, expenses, the efficiency ratio and pre-tax, pre-provision income in the fourth quarter.   
• Capital markets' fixed income average daily revenue for the fourth quarter remained strong at $1.3 million, and noninterest expense improved because of lower variable compensation and legal costs.   
• First Horizon's efforts to reduce loans in the non-strategic segment resulted in a 19 percent decline for 2011 compared to 2010.

Use of non-GAAP measures

Certain measures are included in the text and tables of this release that are non-GAAP, meaning they are not presented in accordance with generally accepted accounting principles (GAAP) in the U.S. FHN's management believes such measures are relevant to understanding the capital position and results of the company. The non-GAAP items presented in this release are pre-tax income related to core businesses, tangible common equity to tangible assets, tangible book value per common share and net interest margin computed using net interest income adjusted for FTE (fully taxable equivalent). These measures are reported to FHN's management and board of directors through various internal reports. Additionally, disclosure of the non-GAAP capital ratios provides a meaningful base for comparability to other financial institutions as these ratios have become an important measure of the capital strength of banks as demonstrated by the inclusion in the stress tests administered by the United States Treasury Department under the Capital Assistance Program. Non-GAAP measures are not formally defined by GAAP or codified in the federal banking regulations, and other entities may use calculation methods that differ from those used by FHN. The reconciliation of non-GAAP to GAAP measures and presentation of the most comparable GAAP items is contained in the following table.
