What believers are saying

  • T-Rex won the 2025 HIRE Vets Platinum Medallion, aiding hiring and retention branding.
  • 2026 federal activity shows $12.6 million YTD obligations across eight award actions.
  • Awards on May 8, 2026 and March 6, 2025 keep pipelines active.

What critics are saying

  • Net federal obligations fell from FY2024 to FY2025, signaling uneven recompete execution.
  • Commerce concentration reached 97.8%, making one agency loss a major revenue shock.
  • No current layoffs or litigation surfaced, but contract dependence creates existential program-churn risk.

What makes T-Rex Solutions unique

  • AWS Advanced Tier Services Partner status on February 3, 2026 strengthens cloud credibility.
