AI Summary

6.0
Neutral

AMTM is a margin-led turnaround, not a revenue-growth story: its record EBITDA margin, rising EPS, and faster-than-planned deleveraging can re-rate the stock if higher-quality backlog converts into durable cash flow, but investors should wait for revenue stabilization amid NASA insourcing, contract delays, and still-material leverage.
