Did Stronger Profitability And Reaffirmed Revenue Guidance Just Shift Amentum Holdings' (AMTM) Investment Narrative?

Earlier this month, Amentum Holdings, Inc. reported second-quarter 2026 results showing broadly flat sales at US$3,478 million but a sharp improvement in net income to US$54 million, and reaffirmed full-year revenue guidance of US$13.95 billion to US$14.30 billion.
