FIRST HORIZON NATIONAL CORPORATION
MANAGEMENT'S DISCUSSION AND ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION

GENERAL INFORMATION

First Horizon National Corporation (FHN) is a national financial services institution. >From a small community bank chartered in 1864, FHN has grown to be one of the top 30 largest bank holding companies in the United States in terms of asset size.

Approximately 13,000 employees provide a broad array of financial services to individual and business customers through hundreds of offices located in 46 states.

FHN companies have been recognized as some of the nation's best employers by AARP, Working Mother and Fortune magazines. FHN also was named one of the nation's 100 best corporate citizens by Business Ethics magazine.

FHN provides a broad array of financial services to its customers through three national businesses. The combined strengths of our businesses create an extensive range of financial products and services. In addition, the corporate segment provides essential support within the corporation.

For the purpose of this management's discussion and analysis (MD&A), earning assets have been expressed as averages, and loans have been disclosed net of unearned income. The following financial discussion should be read with the accompanying consolidated financial statements and notes. A glossary is included at the end of the MD&A to assist with terminology.

FORWARD-LOOKING STATEMENTS

This MD&A contains forward-looking statements with respect to FHN's beliefs, plans, goals, expectations, and estimates. Forward-looking statements are statements that are not a representation of historical information but rather are related to future operations, strategies, financial results or other developments. The words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “should,” “is likely,” “will,” “going forward,” and other expressions that indicate future events and trends identify forward-looking statements. Forward-looking statements are necessarily based upon estimates and assumptions that are inherently subject to significant business, operational, economic and competitive uncertainties

and contingencies, many of which are beyond a company's control, and many of which, with respect to future business decisions and actions (including acquisitions and divestitures), are subject to change. Examples of uncertainties and contingencies include, among other important factors, general and local economic and business conditions; expectations of and actual timing and amount of interest rate movements, including the slope of the yield curve (which can have a significant impact on a financial services institution); market and monetary fluctuations; inflation or deflation; investor responses to these conditions; the financial condition of borrowers and other counterparties; competition within and outside the financial services industry; geopolitical developments including possible terrorist activity; natural disasters; effectiveness of FHN's hedging practices; technology; demand for FHN's product offerings; new products and services in the industries in which FHN operates; and critical accounting estimates. Other factors are those inherent in originating and servicing loans including prepayment risks, pricing concessions, fluctuation in U.S. housing prices, fluctuation of collateral values, and changes in customer profiles. Additionally, the actions of the Securities and Exchange Commission (SEC), the Financial Accounting Standards Board (FASB), the Office of the Comptroller of the Currency (OCC), the Board of Governors of the Federal Reserve System, and other regulators; regulatory and judicial proceedings and changes in laws and regulations applicable to FHN; and FHN's success in executing its business plans and strategies and managing the risks involved in the foregoing, could cause actual results to differ. FHN assumes no obligation to update any forward-looking statements that are made from time to time. Actual results could differ because of several factors, including those presented in this Forward-Looking Statements section.

FINANCIAL SUMMARY

Earnings for 2005 were $438.0 million, or $3.40 diluted earnings per share, including the cumulative effect of a change in accounting principle. Earnings before the unfavorable cumulative effect ($3.1 million, net of taxes) were $441.1 million or $3.42 diluted earnings per share. Earnings for 2004 were $454.4 million, or $3.54 diluted earnings per share.

Generally, FHN's performance in 2005 was driven by Retail/Commercial Banking which contributed 74 percent of pre-tax income. National expansion continues to favorably impact the bank's performance through successful cross-sell penetration to mortgage customers and expansion of the banking franchise into new markets. Additionally, FHN's leading market position in Tennessee has grown through an expanding sales force, the addition of financial centers in a key metropolitan market and successful marketing to customers of merging banks. The success of these initiatives can be seen through loan growth of 18 percent and deposit growth of 12 percent compared to 2004. Asset quality indicators also remained positive with a net charge-off ratio of 21 basis points compared to 27 basis points in 2004.

Mortgage Banking produced 29 percent of pre-tax income in both 2005 and 2004. Results for 2005 were favorably impacted by a 17 percent increase in mortgage loan originations and a similar increase in the associated revenues. This growth was led by a 25 percent increase in home-purchase originations as expansion of the sales force increased market share. In addition, fees associated with mortgage servicing increased 22 percent as the servicing portfolio grew, and servicing profitability continued to improve as the servicing cost per loan decreased 10 percent. However, continued flattening of the yield curve during 2005 unfavorably impacted Mortgage Banking's results through

compression of the spread on the warehouse and unfavorable net hedge results and trading securities valuations.

Capital Markets contributed four percent of pre-tax income in 2005 as it continued to be negatively impacted by the flattening of the yield curve with reduced revenues from fixed income products and compressed spread on securities inventories. However, revenues continued to reflect strong diversification as revenue from fee sources other than fixed income increased 10 percent in 2005, primarily due to increased fees from investment banking and loan sales activities.

The Corporate segment, which absorbs costs associated with supporting the corporate structure, yielded a pre-tax loss of $45.2 million, or a negative seven percent of pre-tax income, in 2005.

2005 results include a charge of $3.1 million, net of taxes, or $0.02 diluted earnings per share, reflecting the cumulative effect of a change in accounting principle related to the adoption of FASB Interpretation No. (FIN) 47, “Accounting for Conditional Asset Retirement Obligations.” FIN 47 requires recognition of a liability at the time of acquisition or construction for assets that will require certain remediation expenditures when the assets are removed from service. The adoption of FIN 47 is not expected to have a material effect on earnings in 2006. In addition, the adoption of Staff Accounting Bulletin (SAB) No. 105 in 2004, which prohibited the inclusion of estimated servicing cash flows within the valuation of interest rate lock commitments, lowered pre-tax earnings by $8.4 million in 2004 and diluted earnings per share by $0.04. FHN previously included a portion of the value of the associated servicing cash flows when recognizing loan commitments at inception and throughout their lives. This impact was a one-time accounting change and does not affect the ongoing economic value of this business.

Return on average shareholders' equity and return on average assets for 2005 were 20.4 percent and 1.20 percent, respectively. Excluding the cumulative effect, return on average shareholders' equity and return on average assets were 20.6 percent and 1.21 percent, respectively, compared to 23.9 percent and 1.66 percent in 2004. Total assets were $36.6 billion and shareholders' equity was $2.3 billion on December 31, 2005, compared to $29.8 billion and $2.0 billion, respectively, on December 31, 2004. The increase in total assets resulted from growth in Capital Markets' balance sheet due to the 2005 acquisition of the fixed income business of Spear, Leeds and Kellogg (SLK) and loan growth in Retail/Commercial Banking.

BUSINESS LINE REVIEW

Retail/Commercial Banking

Pre-tax income increased 21 percent to $475.1 million in 2005 compared to $392.5 million in 2004. Retail/Commercial Banking contributed 74 percent of total pre-tax income in 2005 compared to 59 percent in 2004. Total revenues increased 16 percent, or $191.9 million, in 2005.

Net interest income increased 24 percent to $859.1 million in 2005 from $694.1 million in 2004. The increase in net interest income is primarily attributable to 18 percent loan growth, with commercial loans growing 30 percent to $8.7 billion from $6.7 billion and retail loans growing 9 percent to $9.5 billion from $8.7 billion. This growth resulted from expansion of the sales force, which increased market share in the core bank, as well as cross-sell opportunities in FHN's national markets with a substantial mortgage presence. Deposit account balances increased 12 percent compared to 2004. Net interest margin in Retail/Commercial Banking was stable in 2005 at 4.28 percent compared to 4.31 percent in 2004.

Noninterest income grew 6 percent, or $26.9 million, led by an increase of $15.7 million in revenue from loan sales and securitizations of home equity lines of credit (HELOC) and second-lien mortgages as FHN continues to utilize securitizations to manage liquidity and fund new loan growth. Partially offsetting this was a negative impact of $14.5 million, which resulted from the write-off of net capitalized expenses on HELOC held for sale as they prepaid faster than anticipated. Merchant

processing fees grew 18 percent, or $13.5 million, reflecting increased volume from existing customers as well as an expanded customer base. Fees from deposit services charges increased 5 percent, or $7.7 million, reflecting deposit growth. As FHN continues to divest non-strategic activities, results for 2005 included $7.0 million of divestiture gains from the sale of three financial centers. Similarly, in 2004 divestiture gains of $7.0 million resulted from the sale of certain merchant relationships and an insurance subsidiary.

The provision for loan losses increased to $67.1 million in 2005 from $48.4 million in 2004 as the loan portfolio grew by 18 percent. This increase included $3.8 million in 2005 related to losses in the areas impacted by Hurricanes Katrina and Rita. The net charge-off ratio continued to remain at low levels with 21 basis points in 2005 compared to 27 basis points in 2004, reflecting the stable risk profile of both the commercial and retail loan portfolios.

Noninterest expense was $827.0 million in 2005 compared to $736.4 million in 2004 reflecting higher personnel costs which were largely attributable to national expansion initiatives. The efficiency ratio for retail/commercial banking improved to 60.4 percent in 2005 from 62.6 percent in 2004.

Mortgage Banking

Pre-tax income was $191.6 million in 2005 compared to $195.2 million in 2004. Mortgage Banking contributed 29 percent of total pre-tax income in 2005 and 2004. Total revenues increased 6 percent, or $39.9 million, in 2005.

Net interest income decreased 4 percent to $146.8 million in 2005 from $153.4 million in 2004. The warehouse grew 19 percent; however, the flattening of the yield curve resulted in compression of the spread on the warehouse. Spread on the warehouse was 2.47 percent in 2005 compared to 3.80 percent for 2004.

Noninterest income increased 10 percent to $511.4 million in 2005 compared to $464.9 million in 2004. Noninterest income consists primarily of mortgage banking-related revenue, net of costs, from the origination and sale of mortgage loans, fees from mortgage servicing and mortgage servicing rights (MSR) net hedge gains or losses. Mortgage servicing noninterest income is net of amortization, impairment and other expenses related to MSR and related hedges.

Mortgage loan origination volumes increased 17 percent to $35.7 billion in 2005 from $30.5 billion in 2004, as home purchase-related originations grew 25 percent, or $4.2 billion, and refinance activity grew 7 percent, or $1.0 billion. The increase in home purchase originations demonstrates FHN's success in executing its strategy to grow the purchase market and reflects a sales force of 2,600, which increased by 200, or 9 percent, from 2004. Loans delivered into the secondary market increased 18 percent to $34.6 billion from $29.3 billion. Net revenue from origination activity increased 17 percent to $398.7 million from $339.8 million in 2004.

The mortgage-servicing portfolio (which includes servicing for ourselves and others) grew 10 percent to $95.3 billion on December 31, 2005, from $86.6 billion on December 31, 2004. Total fees associated with mortgage servicing increased 22 percent to $280.2 million from $230.3 million, reflecting growth in the servicing portfolio and the favorable impact of lower prepayment activity. The growth in the servicing portfolio and rising interest rates led to a 26 percent increase in capitalized mortgage servicing rights and a 24 percent, or $36.2 million, increase in amortization expense compared to 2004. In addition, net servicing revenues were unfavorably impacted by a decline in net hedge gains of $41.1 million in 2005 as the continued flattening of the yield curve negatively impacted income from swaps and rising interest rates led to increased option expense.

Noninterest expense increased 10 percent to $466.0 million in 2005 compared to $423.2 million in 2004 due to costs associated with the increased volume of loans delivered into the secondary market. However, as a result of reduced refinancing activity and improvements in processes and technology, productivity improved resulting in a 10 percent reduction of servicing costs per loan compared to year-end 2004.

Capital Markets

Pre-tax income declined from $88.2 million in 2004 to $23.7 million in 2005 primarily due to a decrease in fixed income revenues and net interest income. Total revenues were $339.3 million in 2005 compared to $389.1 million in 2004.

Net interest income decreased $33.8 million, reflecting a $19.4 million incremental cost of equity charge, largely related to the capital requirements of the SLK acquisition in first quarter 2005, and the compression of the spread on Capital Markets' securities inventory resulting from the flattening of the yield curve.

Revenues from fixed income sales decreased $30.8 million from 2004, while revenues from other fee sources increased $14.8 million. Revenues from other fee sources include fee income from activities such as loan sales, investment banking, equity research, portfolio advisory and the sale of bank-owned life insurance. Revenue from these other sources represented 45 percent of total noninterest income in 2005 compared to 39 percent in 2004 and increased 10 percent to $165.6 million from $150.8 million, primarily due to increased fees from investment banking and loan sales activities.

Noninterest expense increased 5 percent, or $14.7 million, primarily due to amortization and other increased costs resulting from the SLK acquisition and the acquisition of the assets of Alterity Partners, LLC (Alterity) on September 23, 2004.

Corporate

The Corporate segment's results yielded a pre-tax loss of $45.2 million in 2005 compared to a pre-tax loss of $9.1 million in 2004. Net security losses were $.6 million in 2005 compared to net security gains of $19.8 million in 2004 resulting from the sale of debt securities as the size of the investment portfolio was temporarily reduced to balance an increase in loans held for sale resulting from a delay in the closing of a securitization and from net gains due to the liquidation of a holding company investment. Results in 2005 include $10.8 million in dividend expense on $300 million of noncumulative perpetual preferred stock issued in first quarter 2005.

INCOME STATEMENT REVIEW – 2005 COMPARED TO 2004

Total revenue increased 7 percent to $2,383.8 million from $2,219.4 million in 2004, including a 15 percent increase in net interest income and a 3 percent increase in noninterest income. A more detailed discussion of the major line items follows.

NET INTEREST INCOME

Net interest income increased 15 percent to $984.1 million in 2005 from $856.3 million in 2004 as earning assets grew 35 percent to $31.9 billion and interest-bearing liabilities grew 40 percent to $27.4 billion in 2005. See also the Consolidated Average Balance Sheet and Related Yields and Rates table.

The activity levels and related funding for FHN's mortgage production and servicing and capital markets activities affect the net interest margin. These activities typically produce different margins than traditional banking activities. Mortgage production and servicing activities can affect the overall margin based on a number of factors, including the size of the mortgage warehouse, the time it takes to deliver loans into the secondary market, the amount of custodial balances, and the level of MSR. Capital Markets' activities tend to compress the margin because of its strategy to reduce market risk by economically hedging a portion of its inventory on the balance sheet. As a result of these impacts, FHN's consolidated margin cannot be readily compared to that of other bank holding companies. Table 1 details the computation of the net interest margin for FHN for the last three years.

The consolidated net interest margin was 3.08 percent for 2005 compared to 3.62 percent for 2004. This compression in the margin occurred as the net interest spread decreased to 2.64

percent from 3.33 percent in 2004 while earning assets and net interest income increased. The decline in the margin is attributable to two items, the acquisition of SLK and a flatter yield curve. The acquisition of SLK in first quarter 2005 increased the negative pressure on the corporate margin as Capital Markets' balance sheet grew $3.6 billion. In addition, Mortgage Banking negatively impacted the corporate margin in 2005 as the flattening of the yield curve decreased spread on the warehouse by 133 basis points to 2.47 percent.

Table 1 - Net Interest Margin

In the near-term, a modest compression of the net interest margin is expected as flattening of the yield curve negatively impacts the spread on the mortgage warehouse. Over the long term, FHN's strategies to manage the interest rate sensitivity of the balance sheet position are designed to allow the net interest margin to improve in a higher interest rate environment. Flattening in the spread between short-term and long-term interest rates generally has an unfavorable impact on net interest margin, primarily from narrower spreads on the mortgage warehouse and capital markets inventories.

Table 2 shows how the changes in yields or rates and average balances compared to the prior year affected net interest income.
