Significant Contract Modifications ($10M+) — June 03, 2026
This digest covers two civilian contracts totaling $357.97M, with zero defense-related awards. The dominant theme is non-defense, mission-critical services: Tetra Tech's $218.6M firm fixed-price delivery order from the Department of State for Ukraine humanitarian demining is the highest-conviction signal, offering multi-year revenue visibility and alignment with geopolitical priorities. The California Institute of Technology's $139.4M cost-no-fee NASA contract for the NuSTAR mission provides stable but low-margin, long-term revenue. Key risks include Tetra Tech's performance risk under a fixed-price contract and the low profitability of Caltech's cost-no-fee arrangement.
