(LYNCHBURG, Va. – June 14, 2024) – BWX Technologies, Inc. (NYSE: BWXT) today announced a contract award from the U.S. Department of Energy, National Nuclear Security Administration (DOE/NNSA) for management and operations of the Pantex Plant. Following an initial term of five years, NNSA has the ability to award three additional five-year option periods. If all contract options are exercised, the contract will span 20 years at a funding level of approximately $30 billion.

The NNSA announced the contract was awarded to PanTeXas Deterrence LLC (PXD). PXD is a joint venture led by a BWX Technologies, Inc. (BWXT) subsidiary – it also includes Fluor; SOC, A Day & Zimmermann Company; and The Texas A&M University System.

Pantex represents a key nuclear production capability in the nation’s Nuclear Security Enterprise. Pantex, located near Amarillo, Texas, is responsible for maintaining the safety, security, and effectiveness of the nation’s nuclear weapons stockpile. Work performed at Pantex includes support of the nuclear weapons life extension programs; nuclear weapons surveillance, assembly and dismantlement; the development, testing, and fabrication of high explosive components; and interim storage and surveillance of plutonium pits.

“This is an important contract win for us and leverages our unique core competencies and capabilities in nuclear operations,” said Heatherly Dukes, president of BWXT’s Technical Services Group. “The PanTeXas Deterrence team was purpose-built to bring the very best of industry experience together to meet crucial global security imperatives. We look forward to getting started with a strong emphasis on safe and secure operations in full support of NNSA’s integrated Nuclear Security Enterprise.”

PanTeXas Deterrence will assume operations from the current contractor following a four-month transition period that will begin on a date yet to be determined.
