AI Summary

6.0
Neutral

PWR's record $53.4B backlog and accelerating margin-backed cash flow validate a durable grid-infrastructure growth runway, but at ~75x earnings investors should own it only if they expect continued flawless project execution, margin resilience, and debt discipline to justify the premium valuation.
