Simplify's Take

What believers are saying

  • February 2026 bought Radiological Solutions, expanding nuclear engineering capabilities immediately.
  • September 2025 bought Integrity Specialists, boosting natural-gas pipeline inspection scale.
  • MidOcean still labels SI Solutions a current portfolio company, signaling continued capital support.

What critics are saying

  • MidOcean's roll-up strategy increases integration failure risk across 14 offices and 600 employees.
  • Nuclear and pipeline work faces strict NRC, PHMSA, and client audit scrutiny.
  • A major client loss or failed acquisition integration would cripple the platform's valuation.

What makes SI Solutions unique

  • MidOcean backed SI Solutions owns engineering, testing, and inspection across critical infrastructure.
  • Its platform spans nuclear, pipeline, power, process, and structural engineering niches.
  • Acquisitions of SC Solutions, Integrity Specialists, and Radiological Solutions broaden technical depth.
