AI Summary

6.0
Neutral

MTZ's power- and data-center infrastructure pivot, strengthened by Superior and a $21.4B backlog, creates a compelling growth runway, but the investment hinges on proving that rapid project scaling converts into sustained free cash flow amid rising leverage and thin margins. Investors should prioritize receivables, working-capital normalization, and Superior integration before treating the oversold share price as a durable entry point.
