Amentum: Multiple Re-Rating Incoming
Amentum is deeply undervalued, trading at less than 9x forward earnings and 8x EV/EBITDA, with strong government-aligned tailwinds. AMTM's $47.8B backlog and shift toward higher-margin, fixed-price contracts position it for margin expansion and potential multiple re-rating. Deleveraging from 4.1x to a 3.0x net debt/EBITDA target, with recent refinancing saving ~$19.6M in annual interest, will unlock shareholder value.
