What believers are saying

NextGen won a $14.1 million Air Force WA3S SBIR Phase III in May 2026.

What critics are saying

Federal spend is concentrated: DoD, DHS, and GSA drove 2026 obligations.
The $26.6 million DOJ OST contract ends in March 2027, creating renewal risk.
Losing GSA Schedule and OASIS+ access would collapse NextGen's federal pipeline.
