EXHIBIT 99.1

Core Business Profitability Up, Non-Performing Loans Down at First Horizon

Company Launches $100 Million Share Repurchase Program

MEMPHIS, Tenn., Oct. 17, 2011 (GLOBE NEWSWIRE) -- Third quarter financial results show First Horizon National Corp. (NYSE:FHN) ramped up core business profitability and significantly lowered non-performing loans. Balance sheet trends generally were favorable and the company continued to make progress on lowering expenses in core businesses, but environmental costs remained elevated primarily from increased GSE-related mortgage repurchase provision expenses. First Horizon has also launched a program to repurchase up to $100 million of its common stock in the open market or in privately negotiated transactions, subject to market conditions, by the end of August 2012.

"We remain focused on controlling what we can control in this challenging environment. Our third quarter results show that we're making solid progress in strengthening First Tennessee, our regional banking business, and FTN Financial, our capital markets business," said Bryan Jordan, First Horizon's CEO. "I'm proud of the work our employees do day in and day out to help our customers have an unparalleled experience when they do business with us."

Financial results

• Net income available to common shareholders improved to $36.1 million, compared to second quarter's net income of $20.0 million.
• Net income in core businesses improved to $94.4 million, up from $26.9 million in the second quarter.
• Diluted earnings per share were $0.14 for the quarter, up from last quarter's EPS of $0.08.

Core business strength

• Regional bank pre-tax income was up 26 percent compared to last quarter, and total revenue grew 2 percent, driven by higher net interest income and steady fee income. Period-end loans improved 5 percent from last quarter, driven by loans to mortgage companies and corporate borrowers and asset-based lending. According to recent FDIC data, First Tennessee's deposits in Tennessee improved 6.5 percent over last year, more than two and one-half times the growth rate in First Tennessee's markets. In Middle Tennessee, deposits grew nearly 7.5 percent, the fastest among the top banks. 
• Capital markets pre-tax income was $27.9 million in the third quarter, compared to a pre-tax loss of $19.9 million in the second quarter, which included a $36.7 million litigation expense. Revenues improved 26 percent as fixed income average daily revenue increased to $1.4 million in the third quarter from $1.1 million in the second quarter. 
• In the corporate segment, pre-tax income was $18.6 million for the third quarter, which included $35.1 million of securities gains from the sale of Visa stock. That compares to a pre-tax loss of $26.8 million in the second quarter.
• The pre-tax loss in the non-strategic segment for the third quarter was $97.9 million, compared to a $12.6 million loss in the second quarter. The higher loss was driven primarily by an increase in mortgage repurchase expense of $28 million and an increase in provision for loans losses due to non-performing loan sales.

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 net 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.
