ABX Air(ABXA Quote) shares tumbled 14% after the air cargo company said a major customer plans to reduce the services it needs. ABX also posted fourth-quarter results that fell below expectations. The company said DHL will cut a range of services that ABX provides under its hub and line-haul services agreement in 2006. ABX estimates the line-haul and Allentown services totaled $292.3 million last year. "While the loss of DHL revenues associated with these services is not welcome news, we believe that the company is positioned to replace the affected earnings and cash flows through continued growth in its non-DHL business volumes," ABX said in a statement.

Separately, ABX said it earned $9.1 million, or 16 cents a share, in the fourth quarter, with revenue of $396.6 million. Two analysts polled by Thomson First Call expected earnings of 27 cents a share. A single analyst was expecting revenue of $430 million. During the year-earlier period, the company earned $18.1 million, or 31 cents a share, on revenue of $361.4 million. ABX Air blamed the earnings decline on lower attainment of the revenue incentives under its hub and line-haul services agreement with DHL. Shares were trading down $1.15 to $6.86.
