Booz Allen Hamilton Inc. has $809,754,946 fully committed VA delivery order (time-and-materials, $317.9M outlayed) for IT operations transformation through 2025-01-22, supporting ~$140-145M annual revenue with low pricing risk.

$163M (2022) + $147M (2019) HHS modifications for ebolavirus vaccine R&D/manufacturing through 2030, with $150.7M outlayed and potential to $391M including options.

Nelson Environmental Remediation USA Ltd. faces high pricing risk on $72.6M firm-fixed-price USAID dioxin remediation contract with only $10.7M (15%) outlayed early in 6.6-year period.

Nonprofit Albert B. Sabin Vaccine Institute, Inc. holds two HHS contracts totaling $310M but lacks direct equity exposure as tax-exempt entity.

Albert B. Sabin Vaccine Institute's HHS contracts offer upside via option exercises from $310M obligated to $391M ceiling for ebolavirus vaccine manufacturing/R&D.

Booz Allen Hamilton's VA IT services could see extensions/modifications beyond $810M as $318M outlayed supports steady ~$140M annual revenue.
