AMTM Stock Forecast & Price Target

Amentum Holdings Inc. has experienced a notable increase in its stock price, rising 29.4% over the past month, significantly outperforming the S&P 500 during the same period. The company’s strong financial performance, particularly in 4QFY25, is attributed to improved margins from fixed-price work, effective cost synergies, and robust program execution, resulting in better-than-expected adjusted EBITDA and earnings per share. Furthermore, Amentum's status as the largest government services provider positions it well for growth in high-potential markets such as nuclear energy and digital infrastructure, which are expected to enhance overall profitability due to their favorable margin profiles.

Amentum Holdings Inc. has faced significant challenges recently, indicated by topline and free cash flow misses attributed to a record 43-day government shutdown, which has negatively impacted contract performance and revenue generation. The company anticipates a ~$650 million headwind for FY2026 due to divestitures and revenues transitioning to equity earnings, further complicating its financial outlook. Additionally, despite locked contracts that yield less than 5% of revenues up for recompete, the expectation of flat sales in 1QFY26 coupled with external factors suggests ongoing pressure on the stock's performance.
