FOR IMMEDIATE RELEASE

ARKANSAS BEST CORPORATION ANNOUNCES
SECOND QUARTER INCOME FROM CONTINUING OPERATIONS
OF $1.13 PER SHARE;
ABF^Ò’s OPERATING RATIO IS 90.1%

     (Fort Smith, Arkansas, July 24, 2006) — Arkansas Best Corporation (Nasdaq: ABFS) today announced second quarter 2006 net income of $32.3 million, or $1.26 per diluted common share. Income from continuing operations was $29.0 million, or $1.13 per diluted common share, compared to second quarter 2005 income from continuing operations of $22.6 million, or $0.88 per diluted common share. Arkansas Best’s second quarter 2006 revenue was $479.3 million, an increase of 12.0% over second quarter 2005 revenue of $427.9 million.

     As previously announced, in June 2006 Arkansas Best completed the sale of Clipper Exxpress, its former intermodal transportation subsidiary. Arkansas Best’s discontinued operations include an after-tax gain on the sale of Clipper of $0.12 per common share, which is subject to adjustments based on the final closing balance sheet as of June 14, 2006. In addition, discontinued operations include after-tax income of $0.01 per common share associated with Clipper’s second quarter operating results through the closing date.

ABF Freight System, Inc.^®

     ABF Freight System,Inc. had second quarter 2006 revenue of $466.9 million, a per-day increase of 11.8% over second quarter 2005 revenue of $417.5 million. Second quarter 2006 operating income at ABF was $46.4 million compared to $38.1 million during the second quarter of 2005. ABF’s second quarter 2006 operating ratio was 90.1% versus an operating ratio of 90.9% in the second quarter of 2005. “During a period of healthy revenue and tonnage growth, the employees of ABF enhanced customer satisfaction levels and cargo care, further improving the industry’s best loss and damage experience,” said Robert A. Davidson, Arkansas Best President and Chief Executive Officer. “Our balance of growth and disciplined yield management resulted in an improvement in ABF’s operating profit and the best second quarter operating ratio in over twenty-eight years.”

     ABF’s second quarter 2006 total weight per day increased by 6.4% compared to last year. “ABF experienced solid tonnage increases throughout the quarter as the year-over-year increase in total tonnage grew during each successive month of the second quarter,” said Mr. Davidson. “Second quarter tonnage comparisons were dampened slightly by the timing of the Easter holiday, just as they were helped in this year’s first quarter. When adjusted for the Easter effect, ABF’s second quarter total tonnage per day increased about 7%.”

     “Our year-over-year tonnage trends in July are running at or slightly behind those of the second quarter, although comparisons for this short period are complicated by calendar differences,” said Mr. Davidson.

     Total billed revenue per hundredweight was $25.22, an increase of 5.5% over last year’s second quarter figure of $23.91. Total billed revenue per hundredweight, excluding fuel surcharge, increased by 1.9%. “The industry pricing environment is competitive but firm, consistent with recent quarters. The retention of the April 3rd general rate increase is in line with our expectations, and price increases on contract renewals are acceptable,” said Mr. Davidson. During the second quarter of 2006, ABF continued to experience significant and positive freight profile changes that reduced the reported revenue per hundredweight. Compared to last year, ABF’s second quarter 2006 total weight per shipment increased by 4.7% while total length of haul declined by 1.6%. The combination of higher weight per shipment and shorter length of haul reduce the reported revenue per hundredweight without a corresponding reduction in effective pricing or shipment profitability.

     “Once again, ABF experienced higher growth rates in freight traveling 800 miles or less. In this year’s second quarter, this freight increased by 10.4% compared to last year. As in the past, most of these short-haul shipments are moving in existing network lanes,” said Mr. Davidson. “In April of this year, ABF announced new operating procedures in 52 additional customer service facilities. As a result, ABF’s more flexible regional capabilities are in place in nearly 25% of the locations in its network. In addition, these new regional operating procedures have improved reliability in longer haul lanes. ABF is beginning to market its new next-day and second-day services, branded as the Regional Performance Model or RPM, throughout the East Coast, from Maine to South Carolina. Despite the initial success ABF has experienced with these operational changes, resulting freight is not expected to have a meaningful impact on ABF’s operating results until late this year or early 2007.”

     “ABF’s second quarter productivity, as measured by total weight per labor hour, improved by 1.8% compared to last year’s second quarter. During the quarter, this productivity figure was at its highest level since the third quarter of last year. “Freight-handling productivity continues to be positively impacted by increases in ABF’s total weight per shipment,” said Mr. Davidson. “While freight-handling productivity has improved, ABF has continued to maintain one of the best cargo claims ratios in the LTL industry. During the second quarter, ABF’s cargo claim ratio, a measure of net cash payouts to revenue, was 0.67%. This compares to ABF’s cargo claims ratio of 0.78% for the combined years of 2004 and 2005. Also, as we expected, ABF’s year-to-date workers’ compensation expenses as a percent of revenue returned to historical levels.”

Common Stock Purchase

     During the second quarter of 2006, Arkansas Best purchased 200,000 shares of its common stock in the open market for an aggregate cost of $8.3 million. These common shares were added to the company’s treasury stock. Since January 2003, Arkansas Best has purchased 1,143,150 shares totaling $37.6 million. Under a program announced in July 2005, Arkansas Best currently has authorization to purchase up to an additional $37.4 million of its common stock. Arkansas Best plans to continue making open-market purchases of its stock on an opportunistic basis.
