Company to Deliver Dynamically Scalable Computing Power, On-Demand

Amentum (NYSE: AMTM), a leader in advanced technology and engineering solutions, has won a $120 million computer processing award from the Defense Information Systems Agency. Through the Z-series chipset Processor Capacity Services contract, Amentum will deliver dynamically scalable computing power for the agency "on-demand."

"Amentum’s proven ability to manage an entire hardware lifecycle expertly suits DISA's processing needs. Our processor capacity solution routinely exceeds 99.999% availability, ensuring systems are performing 24/7/365,” said Mark Walter, president of Amentum’s Engineering & Technology Group. "Our track record of delivery excellence in hardware lifecycle solutions over the past two decades has firmly established Amentum as a trusted prime contractor for DISA."

Under the contract, Amentum will provision and maintain all hardware, software, licensing, and operational services while DISA administers and supports the hosting environment. DISA uses Z-series mainframe chips to support computer processing for its strategic partners. Instead of owning the hardware, the agency purchases computing power capacity based on utility.

“DISA’s on-demand approach to computer processing provides maximum flexibility, value, and mission effectiveness. The service model readily adjusts to changing requirements, including increases and decreases in power usage, allowing DISA to pay only for the computing power it uses,” said Travis Mackland, senior vice president of Digital Transformation for Amentum’s Engineering & Technology business. “Amentum expertise delivers efficient, effective, and reliable solutions to support DISA’s mission.”

The Z-series chipset Processor Capacity Services, or PCS, contract includes a five-year base period with five additional one-year option periods.
