ABX Air, Inc.

Reports First Quarter Earnings

of $6.0 Million

WILMINGTON, Ohio—May 3, 2004—ABX Air, Inc. (OTC: ABXA.OB) today reported that for the quarter ended March 31, 2004, revenues were $276.7 million and net earnings were $6.0 million, or $0.10 per diluted share. For the first quarter of 2003, ABX earned $3.7 million, or $0.06 per diluted share on revenues of $310.7 million.

ABX became an independent public company effective August 16, 2003, as a result of the separation from its former parent company, Airborne, Inc. (“Airborne”), which was acquired by DHL Worldwide Express B. V. (“DHL”). Effective at separation, ABX entered into two cost-plus commercial agreements with Airborne/DHL—an aircraft, crew, maintenance and insurance agreement (“ACMI”), and a hub and line-haul services agreement (“Hub Services”). Both contracts generally provide compensation to ABX on a cost-plus basis, with a base mark-up of 1.75% and a potential to earn incremental mark-ups depending on the attainment of contractually specified cost and service goals. The separation from Airborne makes financial comparisons of 2004 results to pre-separation 2003 results difficult for several reasons, including differences in the mark-up available under the two commercial agreements as compared to the mark-up convention used by Airborne pre-separation, the timing of revenue recognition under the two current contracts, and changes in ABX Air’s cost structure which resulted from the separation. These cost structure changes include lower depreciation due to a significant impairment charge incurred at separation, and lower interest and tax expenses.

For the first quarter of 2004, ABX Air’s net earnings of $6.0 million included $4.7 million from its two contracts with Airborne/DHL. The base mark-up of 1.75% of eligible costs was $3.7 million, while the incremental mark-up associated with attainment of cost goals accounted for an additional $1.0 million. Under the two contracts, any incremental mark-up earned during the first three quarters of each fiscal year is based solely on achieving certain cost related goals, with a maximum incremental mark-up of approximately 0.54%. During the first quarter 2004, ABX Air earned 0.46% of incremental mark-up or 85.2% of the maximum available under the two contracts due to higher package volumes, lower maintenance expenses and improved productivity compared to budget.

Total packages handled in the first quarter grew 7.3% to 122.8 million, compared to 114.4 million packages in the first quarter 2003. The increase in packages handled was driven by growth in Airborne/DHL’s ground product, as well as one additional operating day in the first quarter of 2004 compared to the prior year’s first quarter.

Labor related costs comprise a significant portion of ABX’s total operating costs. Excluding flight and aircraft maintenance employees, where labor hours are not directly related to piece volumes processed on behalf of Airborne/DHL, pieces handled per paid hour in the first quarter 2004 improved 7.8% compared to first quarter 2003. Continued focus on running the sort operation efficiently coupled with less severe weather conditions versus 2003 were the primary reasons for the improvement.

“DHL is pleased with our high quality of service,” stated Joe Hete, President and CEO. “ABX Air is committed to be the premier provider to Airborne/DHL. We are working closely with our primary customer to find synergies in the integration of the DHL and Airborne networks while supporting their growth initiatives within the United States.”

The two commercial agreements with Airborne/DHL allow ABX to earn additional incremental mark-up for meeting certain annual service and cost goals. Incremental mark-up earned on the annual goals is only recognized in the fourth quarter. Maximum incremental mark-up available from the annual component of the cost goal is approximately 0.81% of eligible (full year) costs under both commercial agreements. Maximum incremental mark-up available from the annual service goals is 0.25% of costs subject to mark-up under the ACMI agreement and 0.75% of costs eligible for mark-up under the Hub Services agreement. If ABX’s actual service performance for the first quarter of 2004 is sustained for the full year, the Company would earn incremental mark-up of 0.10% of costs subject to mark-up under the ACMI agreement (40% of maximum mark-up), and 0.65% of costs subject to mark-up under the hub services agreement (86.7% maximum mark-up). Actual service performance for the quarter ended March 31, 2004 is not necessarily indicative of full year service performance, and service results during the last nine months of 2004 may improve upon or detract from actual service results through March 31, 2004.

Non-Airborne/DHL revenue totaled $3.4 million in first quarter of 2004, up 17% from $2.9 million in the 2003 period. Pre-tax profits on non-Airborne/DHL business increased by 0.9 million to $1.3 million. Revenues for air charter services, despite the loss of a significant customer in the first quarter of 2003, were equal to the year ago period at improved margins. Late in

first quarter of 2003, ABX Air lost a significant charter customer whose ability to pay became compromised. That customer accounted for $951,000 of revenue in the first quarter last year. ABX’s focus on providing maintanence and engineering services to other aircraft operators has yielded an increase in revenues from $47,000 for the first quarter of 2003 to $816,000 for the first quarter of 2004.

“We continue to focus on growing our non-Airborne revenues,” Hete continued, “I am pleased with our progress to date and expect steady growth going forward as we continue to develop relationships with other customers, particularly in air charter and maintenance services areas.”

Outlook

“Airborne/DHL remains our largest customer, and we remain focused on providing them with superior service,” Hete said. “They have made a commitment to growing their presence domestically, and we expect the shipment volumes we handle will grow accordingly. As DHL and Airborne complete the integration of their delivery networks, however, I anticipate that they will seek to eliminate duplicative costs, including those related to their service providers. While the scope of services we provide under the two agreements cannot be reduced for the first year, beginning August 16, 2004, Airborne may terminate ACMI aircraft, add, delete or modify the air routes we operate under the ACMI agreement, as well as add, delete or modify the services we provide under the Hub Services agreement. We are striving to remain Airborne’s preferred service provider by continuing to deliver premium service at a reasonable price.”

“An area of additional focus will be to grow our non-Airborne/DHL revenues by developing and expanding services that build on our strengths and expertise,” Hete continued. “This business generally carries better margins than our core business, and we will continue to build the relationships that will drive that business.”
