NASDAQ:SSYS News 31 December 2025

January 30, 2026, 6:30 AM EST. Amentum Holdings (NYSE:AMTM) shares surged 27% over the past month and soared 86% year-over-year, yet its price-to-sales (P/S) ratio remains low at 0.6x compared to the U.S. Professional Services industry's 1.2x median. Despite strong recent revenue growth of 70% last year and 88% over three years, analysts forecast a moderate 2.1% annual growth over the next three years, trailing the sector's 6.5% pace. This modest outlook likely drives investor caution, keeping Amentum's valuation suppressed despite its momentum. The stock's P/S ratio suggests the market expects limited future expansion, reflecting a cautious investor sentiment amid sustained solid revenue performance.
