What believers are saying
- Shermco is expanding into data centers, semiconductors, healthcare, and water/wastewater through PQE.
- Revelio Labs showed 1,799 employees in March 2026, up 11.8% from 2023.

What critics are saying
- Blackstone ownership since October 2025 pressures Shermco for bolt-ons and faster integration.
- Shermco depends on scarce NETA technicians; turnover would stall commissioning backlogs.
- A 2026 slowdown in data-center capex would hit PQE and Shermco’s expansion thesis.
What makes Shermco unique
- Shermco sells NETA-certified field testing, engineering, and commissioning across 41 North American service centers.
- Blackstone bought Shermco on October 27, 2025, backing aggressive add-on acquisition execution.
- PQE’s March 11, 2026 acquisition strengthened Central Texas power-systems engineering and data-center capabilities.
