BLUF: National Technology & Engineering Solutions of Sandia, LLC's (NTESS) contract to manage Sandia National Laboratories has reached $42,571,358,867.68 in total obligations after two June 30, 2026 funding actions.

The National Nuclear Security Administration (NNSA), a semi-autonomous agency within the Department of Energy (DOE), obligated an additional $201,047,466.93 to contract DE-NA0003525 on June 30, 2026, split across two funding-only modifications (No. 298, $44,406,843.82, and No. 299, $156,640,623.11), according to transaction records on USAspending.gov. The contract funds NTESS's continued management and operation of Sandia National Laboratories in Albuquerque, New Mexico.

Why it matters: M&O contracts for NNSA's nuclear security enterprise represent some of the federal government's largest single cost-plus vehicles, and periodic funding modifications like these are the primary mechanism by which NNSA keeps lab operations funded year over year. For contractors and subcontractors in the nuclear security supply chain, these obligation increases are a direct signal of continued program funding flow into Sandia's site operations.

By the numbers:

• Total obligations to date: $42,571,358,867.68
• Latest funding actions: $201,047,466.93 (June 30, 2026, mods 298 and 299)
