Significant Contract Modifications ($10M+) — June 03, 2026

Tetra Tech's firm fixed-price delivery order from the Department of State for humanitarian demining in Ukraine provides a multi-year revenue stream of up to $81.5M/year, supported by bipartisan congressional consensus and Ukraine supplemental funding.

The cost-no-fee contract for the NuSTAR mission provides Caltech with stable, low-risk revenue averaging $7M/year, reinforcing its position in space science R&D and NASA's commitment to small explorer programs.

Tetra Tech's $218.6M firm fixed-price contract carries performance risk in the high-conflict Ukraine environment; only $30.4M has been outlaid so far, suggesting potential ramp-up challenges or milestone delays.

Caltech's $139.4M cost-no-fee NASA contract yields no profit, limiting financial upside despite long-term stability; any cost overruns or schedule delays could impact future awards.

Tetra Tech's $218.6M Ukraine demining contract positions the firm for follow-on awards as geopolitical priorities sustain humanitarian assistance funding; the $407.6M ceiling suggests potential for additional task orders.

Caltech's long-term NASA contract demonstrates institutional trust and mission criticality, potentially leading to future space science R&D awards as NASA continues investing in small explorer programs.

Both contracts are civilian: Tetra Tech's State Department demining aligns with geopolitical humanitarian priorities, while Caltech's NASA contract supports long-term space science R&D, highlighting stable non-defense procurement.
