AMTM Stock Forecast & Price Target

Amentum Holdings Inc. has demonstrated a robust performance with its shares appreciating by 29.4% over the past month, significantly outperforming the S&P 500, driven by favorable developments in the nuclear market and strong fourth-quarter results. The company’s largest segment, Global Engineering Solutions, has benefitted from a strategic focus on higher-margin, fixed-price work, leading to improved cost synergies and margins, which were evidenced by an outperformance in adjusted EBITDA and EPS. Additionally, Amentum's established position as the largest government services provider positions it well for growth opportunities in emerging markets such as nuclear energy, digital infrastructure, and space systems, which are expected to contribute to further margin expansion and overall financial stability.

Amentum Holdings Inc. experienced a significant decline in its stock performance, with shares falling 12.4% following disappointing topline results and free cash flow misses attributed to a lengthy government shutdown. The company faces a notable headwind of approximately $650 million relative to FY2025 due to divestitures and transitions that reduce revenue, alongside an expectation of flat year-over-year sales for the first quarter of FY26. Furthermore, while net leverage has improved to 3.2x with plans for substantial debt repayment, the overall outlook remains negative due to limited revenue recompete opportunities and ongoing operational challenges impacting growth.
