Significant Contract Modifications ($10M+) — June 10, 2026

CACI NSS, LLC won a $777M cost-plus award fee delivery order from GSA for Special Operations Forces Emerging Threats Operations and Planning Support at Fort Bragg, with options bringing total potential to $1.13B. Full and open competition with no set-aside confirms CACI's competitive strength in this high-priority defense niche.

Amentum Services, Inc. secured a $91.7M delivery order with options up to $211.9M from GSA, under full and open competition. The contract provides multi-year visibility through June 2025, but negative outlays and 10 subawards totaling $31.9M introduce execution risk.

TUNNELL CONSULTING INC won a $92.8M delivery order from BARDA (HHS) with potential total of $660.2M through 2035 for biotech and biopharmaceutical R&D support. The labor-hours pricing introduces cost risk, and the company is private, limiting direct investment access.

CACI's $777M single award constitutes 66% of total obligation value in this digest, creating revenue concentration risk if the contract faces protest or funding delays under a continuing resolution.

The $125.5M CDC World Trade Center Health Program contract to Icahn School of Medicine has already ended (potential end 2022-09-30), and re-compete risk exists for follow-on awards in this long-term federal initiative.

BARDA's $92.8M award to TUNNELL CONSULTING with a potential total of $660.2M through 2035 highlights multi-decade government commitment to biotech R&D and medical countermeasure development. The labor-hours pricing and private company status introduce uncertainty, but the trend is clear.

Two of five contracts (CACI and Amentum) are awarded through GSA, totaling $869M, indicating GSA serves as a key procurement conduit for both defense and non-defense support services. This challenges the notion that GSA is solely for civilian spending.
