Parsons Grows U.S. Army Organic Industrial Base Modernization Portfolio with $169.5 Million Award

CHANTILLY, Va., June 16, 2025 (GLOBE NEWSWIRE) -- Parsons Corporation (NYSE: PSN) announced today that the company was awarded a $169.5 million single award contract by the United States Army Corps of Engineers (USACE) Norfolk District to provide design-build delivery services for a new Ammonium Nitrate Solution (ANSol) Tank Farm at Holston Army Ammunition Plant (HSAAP). The four-year contract is new work for the company.

Under this contract, Parsons will provide integrated delivery services for the ANSol tank farm, enabling the HSAAP to increase storage requirements for ANSol, a byproduct of the explosives manufacturing process. The new tank farm will replace HSAAP’s existing storage tanks to support expanded manufacturing at the Government Owned Contractor Operated facility.

“Parsons is a trusted partner in advancing the U.S. Army’s Organic Industrial Base (OIB) Modernization Implementation Plan,” said Jon Moretta, President, Engineered Systems for Parsons. “Holston Army Ammunition Plant has a vital role in ensuring our nation’s warfighters have what they need when they need it to successfully carry out missions around the world. As the number of organic industrial base modernization projects grow, we remain ready to leverage our experience and innovative technology solutions to improve readiness and operations.”

The U.S. Army is currently engaged in a multi-year, multi-billion-dollar plan aimed at modernizing the organic industrial base, which encompasses upgrades to facilities, processes, and workforce capabilities throughout depots, arsenals, and ammunition plants. This award grows Parsons’ role in these efforts and is the company’s third USACE Norfolk District award in four years. In 2023, Parsons was selected to deliver a new Explosive Decomposition Chamber facility at HSAAP, and in 2021, the company was awarded a design-build contract for a new Energetic Waste Incinerator/Contaminated Waste Processor at Radford Army Ammunition Plant.
