(* 2010 and 2009 results adjusted as detailed below.)

Phoenix, AZ — January 24, 2011 — Swift Transportation Company (NYSE: SWFT), a multi-faceted transportation services company and the largest truckload carrier in North America, today reported its results for the three months and year ended December 31, 2010.

Operating revenue for the fourth quarter of 2010 increased 16.8% to $780.4 million compared to $668.3 million for the corresponding quarter of 2009. Excluding fuel surcharge revenue, net revenue increased to $661.6 million for the fourth quarter of 2010, up 13.8% from the fourth quarter of 2009 for the largest quarterly year over year increase in over five years.

The increase in revenue excluding fuel surcharge reflects a 6.8% increase in weekly trucking revenue per tractor and a 4.4% increase in average tractors available for dispatch for the fourth quarter of 2010 compared to the prior year quarter. We were able to achieve the increase in weekly trucking revenue per tractor primarily because of a 5.1% increase in average trucking revenue per loaded mile during the comparative periods, while our loaded miles, or trucking volumes, increased 6.2%. Intermodal revenue grew 20.6% during the fourth quarter of 2010 compared to the fourth quarter of 2009, further contributing to the growth in revenue excluding fuel surcharge.

Jerry Moyes, Chief Executive Officer commented, “Our pricing is improving as customers align with our strong capacity and quality service, allowing us to improve our mix and recapture some of the rate lost during the recession. Demand maintained the pace of improvement over the prior year and was substantially flat with the third quarter of 2010, showing the typical holiday seasonal pattern throughout the quarter.”

Our operating ratio improved 280 basis points to 90.2% for the fourth quarter of 2010 compared with 93.0% for the fourth quarter of 2009 while our Adjusted Operating Ratio (adjusted to net fuel surcharge revenue against fuel expense and to exclude certain special items as detailed below) improved 630 basis points to 85.0% for the fourth quarter of 2010 compared to 91.3% for the fourth quarter of 2009. The operating ratio improvement is primarily attributable to the increase in pricing and utilization noted above as well as continued improvements in our intermodal business and workers compensation costs. We also experienced a reduction in depreciation expense due to reductions in our trailer fleet and delayed replacements on a portion of our tractor fleet, resulting in a lower depreciable basis which is also being spread over an extended life. This aging of the tractors also led to an increase in our maintenance expense, which partially offset the above cost reductions.

For the fourth quarter of 2010, we had a net loss of $48.3 million, or $0.66 per share, compared to a net loss of $357.1 million, or $5.94 per share, in the fourth quarter of 2009. These results in accordance with generally accepted accounting principles in the United States (“GAAP”) include several special items in each period as detailed below, primarily related to our initial public offering and debt refinancing transactions in December 2010, and amendments to our previous senior secured credit facility and second-priority senior secured note indentures in October 2009. Excluding these items from each period, adjusted net income in the fourth quarter of 2010 was $24.6 million compared to a pro forma adjusted net loss of $21.8 million in the fourth quarter of 2009 (see following Actual and Pro Forma Adjusted Net Income (Loss) Reconciliation Table). Results for the 2009 periods are presented on a pro forma basis as if we had been taxed as a subchapter C corporation for income tax purposes for the entire period as discussed below.

In December 2010, we completed a series of deleveraging and refinancing transactions including an initial public offering (“IPO”) of 73,300,000 shares of our Class A common stock, a new senior secured term loan and senior secured revolving credit facility and new senior second lien secured notes. The proceeds from these transactions were used to repay our previous term loan and substantially all of our previous senior secured second lien notes as well as to terminate and settle all of our remaining interest rate swap agreements. These transactions resulted in the following pre-tax charges, which are included in our fourth quarter 2010 results in accordance with GAAP:

•

$22.6 million non-cash equity compensation charge included in salaries, wages, and employee benefits related to certain stock options that vested upon our initial public offering in December 2010; and

•

$95.5 million loss on debt extinguishment related to the premium and fees we paid to tender for our old notes and the non-cash write-off of the deferred financing costs associated with our previous indebtedness that was repaid as noted above.

In October 2009, we amended our previous credit facility and senior notes and converted from a subchapter S to a subchapter C corporation for income tax purposes. This resulted in the following charges, which are included in our fourth quarter 2009 results in accordance with GAAP:

•

$324.8 million of income tax expense to re-establish the Company’s net deferred tax liabilities as a subchapter C corporation; and

•

$3.9 million pre-tax expenses representing transaction costs included in operating supplies and expenses for legal and advisory fees related to the amendments.

The results in accordance with GAAP for the fourth quarters of 2010 and 2009 also include pre-tax expenses of $1.1 million and $11.4 million, respectively, in derivative interest expense for the change in market value of interest rate derivative agreements as well as $4.5 million and $5.3 million, respectively, of intangible assets amortization expense related to Swift’s customer and owner-operator relationships recognized under purchase accounting in conjunction with our going-private transaction in 2007. The results for the fourth quarter of 2009 also include a $4.0 million pre-tax benefit in other income related to the sale of our investment in Transplace, Inc., representing the recovery of a note receivable that had been previously written off.

For the year ended December 31, 2010, our operating revenue increased 13.9% to $2.93 billion compared to $2.57 billion for 2009. Net revenue excluding fuel surcharge revenue was $2.50 billion, up 8.9% over 2009. The increase in revenue excluding fuel surcharge was primarily driven by a 4.7% growth in loaded miles, while our average trucking revenue per loaded mile also increased 1.9% year over year, reflecting a sequential quarterly increase throughout 2010 after a sequential quarterly decrease throughout 2009.

Our operating ratio improved 320 basis points to 91.7% for 2010 compared to 94.9% for 2009 while our Adjusted Operating Ratio improved 490 basis points to 89.0% for 2010 compared to 93.9% for 2009. Finally, Adjusted EBITDA for the year ended December 31, 2010, as defined in our new senior secured credit facility and calculated below, was $497.7 million, up 22.6% from $405.9 million in the prior year. The annual profitability improvement is based on similar trends as noted in the fourth quarter discussion above, reflecting volume and pricing growth coupled with lower deadhead and continued cost containment.

Richard Stocking, President and Chief Operating Officer commented, “As a leadership team, we are very proud of our entire organization. Since 2007, we have implemented in-depth leadership training programs, and created a hyper-focus on key indicators throughout all levels of the organization, which are reviewed regularly. This has created a strong sense of unity throughout the organization, from the drivers to the executive team, and our customers have seen the change, as evidenced by a record number of carrier of the year awards for the second consecutive year. Through these efforts, combined with an improving freight environment and a reduction in industry-wide trucking capacity, we have exceeded our financial targets for the year. Excluding the $22.6 million non-cash equity compensation charge upon the IPO, we achieved our highest quarterly operating income in our company’s history, an accomplishment we are very proud of. Our recent IPO and refinancing transactions have strengthened our balance sheet, allowing us to focus our attention back on our business, as we press on toward Best in Class performance in all areas. Our goal is to achieve sustained, superior performance. We’ve come a long way, but relative to our potential, we believe we have great room for improvement.”

Net loss in accordance with GAAP for the year ended December 31, 2010 was $125.4 million or $1.98 per share, which included the $118.1 million of costs related to our IPO and refinancing as noted in the fourth quarter discussion above and the following pre-tax items: $24.5 million expense for change in market value of interest rate derivative agreements, $1.3 million impairment expense for trailers reclassified to assets held for sale during the first quarter, and $7.4 million of incremental depreciation expense during the first quarter reflecting revised estimates of salvage value and useful lives on approximately 7,000 dry van trailers which management decided during the first quarter to scrap. Net loss in accordance with GAAP for the year ended December 31, 2009 was $435.6 million or $7.25 per share, which included the $328.7 million of credit agreement amendment and tax conversion items noted in the fourth quarter discussion above and the following pre-tax items: $3.7 million gain for change in market value of interest rate derivative agreements, $0.5 million impairment expense for a real estate property during the first quarter, an additional $2.6 million of transaction costs related to the debt amendments and a cancelled bond offering during the third quarter, and a $12.5 million benefit in other income for certain litigation settlement proceeds received during the third quarter. Excluding these items from each period, adjusted net loss in 2010 was $32.8 million compared to a pro forma adjusted net loss of $115.9 million in 2009 (see following Actual and Pro Forma Adjusted Net Income (Loss) Reconciliation Table). The adjusted net loss for 2010 and pro forma adjusted net loss for 2009 have not been adjusted for $19.3 million and $22.0 million, respectively, of intangible assets amortization expense related to the intangible assets recognized under purchase accounting in conjunction with our going-private transaction in 2007.

For the year ended December 31, 2010, our net cash capital expenditures were $126.1 million compared to $1.5 million in the prior year, while the gross value of equipment and facilities acquired through cash, capital lease, or operating lease financing was $239.0 million and $159.4 million in 2010 and 2009, respectively. The increased outlay in 2010 was driven by replacement of older tractors and growth of our container fleet in 2010, while the 2009 expenditures were low as a result of fleet reductions and because we delayed replacements as neither the lower utilization levels of our existing equipment nor the anticipated financial returns justified the investment. At December 31, 2010, we had cash of $47.5 million, excluding restricted cash of $84.6 million held primarily as collateral by our captive insurance subsidiaries. We also had available liquidity of $249.3 million on December 31, 2010, consisting of $246.8 million available on our new and undrawn revolving line of credit, after giving effect for the $153.2 million of letters of credit outstanding under this facility, and $2.5 million available under our accounts receivable securitization facility. Additionally, on January 20, 2011, we sold an additional 6,050,000 shares of our Class A common stock to the underwriters of our IPO at the IPO price of $11.00 per share, less the underwriters’ discount, pursuant to the over-allotment option in the underwriting agreement and received proceeds of $63.2 million in cash.

Mr. Stocking concluded, “We are well positioned to execute according to our plan for 2011, with “green” CSA scores, a driver friendly environment and improved recruiting infrastructure, and room for utilization improvement on our existing equipment to efficiently capture our customers’ growing freight needs.”

In this press release, we present financial results excluding the impact of certain items in measures such as adjusted net income (loss), adjusted operating ratio, and adjusted EBITDA. Such measures are not presented in accordance with GAAP and should be considered in addition to, not as a substitute for, or superior to, measures of financial performance in accordance with GAAP. The calculation of each measure, including a reconciliation to the most closely related GAAP measure and the reasons management believes each non-GAAP measure is useful, are included in the attached schedules.

Swift will hold a live conference call with a slide presentation to discuss these results at 12:30 p.m. Eastern time on Tuesday, January 25, 2011. Participants may access the call using the following dial-in numbers: U.S./Canada: (866) 379-9391; International/Local: (706) 634-0901; Confirmation ID: 37701188.

Forward-looking statement disclosure:

This press release contains statements that may constitute forward-looking statements, which are based on information currently available, usually identified by words such as “anticipates,” “believes,” “estimates, “plans,” “projects,” “expects,” “intends,” “will,” “could,” “may,” or similar expressions which speak only as of the date the statement was made. Such forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Such statements include, but are not limited to, statements concerning the benefits of our IPO and refinancing transactions, our outlook in 2011, including our potential for utilization improvement, our future business focus, goals, potential for improvement and operations, and the use of restricted cash for claims payments in future periods and the corresponding impact on claims accruals.

Actual results may differ from those set forth in the forward-looking statements.

The factors that we believe could affect our results include, but are not limited to: any future recessionary economic cycles and downturns in customers’ business cycles, particularly in market segments and industries in which we have a significant concentration of customers; increasing competition from trucking, rail, intermodal, and brokerage competitors; a significant reduction in, or termination of, our trucking services by a key customer; our ability to sustain cost savings realized as part of our recent cost reduction initiatives; our ability to achieve our strategy of growing our revenue; volatility in the price or availability of fuel; increases in new equipment prices or replacement costs; the regulatory environment in which we operate, including existing regulations and changes in existing regulations, or violations by us of existing or future regulations; the costs of environmental compliance and/or the imposition of liabilities under environmental laws and regulations; difficulties in driver recruitment and retention; increases in driver compensation to the extent not offset by increases in freight rates; potential volatility or decrease in the amount of earnings as a result of our claims exposure through our wholly-owned captive insurance companies; uncertainties associated with our operations in Mexico; our ability to attract and maintain relationships with owner-operators; our ability to retain or replace key personnel; conflicts of interest or potential litigation that may arise from other businesses owned by Jerry Moyes; potential failure in computer or communications systems; our labor relations; our ability to execute or integrate any future acquisitions successfully; seasonal factors such as harsh weather conditions that increase operating costs; and our ability to service our outstanding indebtedness, including compliance with our indebtedness covenants, and the impact such indebtedness may have on the way we operate our business.
