PSN Parsons Corporation

(December 10, 2024) – Parsons Corporation (NYSE: PSN) announced today that the company has formed a joint venture with V2X named Polar Science Alliance (PSA), LLC to pursue the National Science Foundation’s (NSF) Antarctic Science and Engineering Support Contract (ASESC). This mission-critical $8 billion ceiling value single-award indefinite-delivery, indefinite-quantity contract will enable world-class scientific research support services for the United States Antarctic Program (USAP) over the next two decades.

NSF manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean through the USAP, the largest scientific research program in the Antarctic region. The NSF has maintained a pivotal U.S. presence in Antarctica for more than six decades, working to study the Antarctic and its ecosystems, understand the region's impact on global processes such as climate, and leverage Antarctica's unique features for scientific research that cannot be done as well elsewhere.

“Polar Science Alliance stands ready to bring the experience and resources of its parent companies, Parsons and V2X, to the world-class United States Antarctic Program,” said Jon Moretta, President, Engineered Systems for Parsons. “Parsons brings years of experience in polar operations to this joint venture, including work as the modernization designer and builder on the Antarctica Infrastructure Modernization for Science Project. We’re proud to team with V2X for the opportunity to be NSF’s USAP support services partner in enabling the world-class Antarctic science program.”

Parsons is a leader in providing the federal government with solutions to the most complex infrastructure challenges. The company has 55 years of successful and proven polar operations experience beginning in 1970 on the North Slope of Alaska, with capabilities spanning program and construction management, engineering and planning, and logistics. As a global solutions provider, Parsons works in all environments, including Antarctica's freezing temperatures and volcanic rock. The company uses technological innovation and harnesses the potential of artificial intelligence to empower smarter decision-making, drive efficiency, and support clients worldwide across infrastructure, the environment, and national security.

“V2X and Parsons have formed the perfect team to provide support to the NSF and support the USAP for scientific research in Antarctica,” added Ken Shreves, Senior Vice President of Mission Support at V2X. “With work from the Arctic U.S. Space Force base to the West-central Pacific Ocean U.S. Army Kwajalein Atoll, V2X is top support for any geographical and geopolitical environment in the world.”

As a testimony of working in polar climates, V2X has over a decade of large-scale polar operations experience and was recently awarded the follow-on decade supporting the U.S. Space Force in Greenland. In addition, V2X retains over 20 years of science support experience. V2X optimizes operations at every stage of the mission lifecycle, providing better support at lower cost using industry leading practices and lessons learned from a portfolio of global, large magnitude programs in remote, complex, and austere environments. For 80 years, V2X has enhanced operations, maintenance, logistics, engineering, technology, and sustainment for government clients worldwide.
