AI Summary

6.0
Neutral

Sterling is an AI-infrastructure growth play rather than a traditional contractor, but at ~38x earnings investors should only underwrite upside if E-Infrastructure backlog converts into sustained ~20% EBITDA margins and strong cash collection despite lower-margin CEC work and elevated receivables.
