Key Takeaways:
- Amentum Holdings provides mission-critical, technology-driven services to the U.S. government and commercial clients across defense, energy, and intelligence sectors.
- AMTM stock trades near $24, down around 20% year to date, even as the company reaffirms its full-year guidance and secures major new contracts.
- AMTM stock could rise from $24 to around $29 per share by fiscal year 2028, based on 1.9% annual revenue growth, 5.3% operating margins, and a 9.9x P/E multiple.
- That would be a 17.7% total return, or around 7% annualized over the next 2.4 years.
What Happened?
Amentum Holdings, Inc. (AMTM) provides mission-critical services to government and defense clients across more than 80 countries. The company operates through two segments: Critical Mission Solutions, which supports defense and energy programs, and Cyber and Intelligence, which serves national security and intelligence clients.
Jacobs Solutions spun off Amentum in September 2024, so it remains in the early stages of life as a public company. The stock carried strong momentum after the spin before losing significant ground through early 2026.
The contract pipeline has been a bright spot even as the stock declined. Amentum secured a $425 million contract in April 2026 to support California’s aerial firefighting operations. The company also won a $406 million UK contract to engineer small modular reactors, a type of next-generation nuclear energy facility.
A $120 million DISA computer processing award, won in December 2025, added further depth to the backlog. So Amentum is diversifying its government work across energy, defense, and intelligence sectors in multiple countries.
Amentum reported Q1 fiscal year 2026 revenue of $3.24 billion, slightly below the $3.32 billion analyst estimate but consistent with the prior quarterly run rate. Adjusted EPS of $0.54 beat the $0.53 estimate, and management reaffirmed full-year guidance after the report.
The company also amended its credit agreement in late April 2026, placing new $4 billion secured loan facilities to optimize its balance sheet. Investors focused on the revenue miss, but management’s guidance reaffirmation signaled confidence in the second half.
Amentum carries $3.7 billion in net debt and operates on thin margins near 3.4%, so the balance sheet carries real risk. But the company’s Q2 2026 earnings on May 12 offer a near-term catalyst.
Here’s why Amentum stock could still offer measured returns for patient investors who understand the government services model.
What the Model Says for AMTM Stock
We analyzed the upside potential for Amentum stock based on its government contract backlog, diversified defense and energy exposure, and expected margin improvement as the company completes its post-merger integration.
Based on estimates of 1.9% annual revenue growth, 5.3% operating margins, and a normalized P/E multiple of 9.9x, the model projects Amentum stock could rise from $24 to around $29 per share.
That would be a 17.7% total return, or a 7% annualized return over the next 2.4 years.
Our Valuation Assumptions
TIKR’s Valuation Model lets you plug in your own assumptions for a company’s revenue growth, operating margins, and P/E multiple, and calculates the stock’s expected returns.
Here’s what we used for AMTM stock:
1. Revenue Growth: 1.9%
Amentum reported Q1 FY2026 revenue of $3.24 billion, down about 5% from a year earlier. The decline reflects contract completions and the divestiture of the Rapid Solutions product business in mid-2025 for $360 million. New contract wins in California, the UK, and through DISA are replenishing the backlog, so near-term revenue declines should stabilize.
Analysts currently see the forward two-year revenue CAGR at around 1%, reflecting the government services model’s steady but measured growth profile. Amentum competes on contract extensions and specialized capabilities rather than rapid organic expansion. Based on analysts’ consensus estimates, we used 1.9% revenue growth, reflecting modest recovery as new wins convert to recognized revenue.
The company’s Digital Solutions and Global Engineering Solutions segments generated a combined quarterly run rate of about $930 million in Q1 2026. International revenue represented $747 million in Q1, showing genuine geographic diversification. So the 1.9% growth assumption is grounded in the company’s current win rate and pipeline trajectory.
2. Operating Margins: 5.3%
Amentum’s LTM operating profit margin is around 3.4%, but Q1 2026 showed improvement as the EBIT margin rose to 4.3% and SG&A fell to 3.6% of revenue. The company is actively integrating its post-merger structure and reducing costs. Based on analysts’ consensus estimates, we used 5.3% operating margins, reflecting gradual improvement as integration savings flow through the income statement.
Comparable government services firms typically operate at margins in the 5% to 10% range. A 5.3% target sits at the conservative end of that peer group. But it requires consistent contract activity and sustained cost discipline as the new Reston, Virginia headquarters takes shape.
SG&A dropped to $115 million in Q1 2026 from $130 million a year earlier, a reduction of about 12% that signals early discipline. Interest expenses of $74 million per quarter weigh on net margins but should decline as debt is paid down. So the 5.3% operating margin assumption is conservative but directionally reasonable.
3. Exit P/E Multiple: 9.9x
Amentum trades at a next twelve-month P/E of around 9.8x, at the low end of government services peers. Companies like SAIC and Leidos trade at higher multiples because of stronger margins and longer public histories. But Amentum is still building its track record as an independent company.
Based on analysts’ consensus estimates, we maintained a 9.9x exit P/E multiple, reflecting Amentum’s elevated debt, integration execution risk, and limited public market history. The street consensus target price is around $36, implying meaningful upside from the current $24 level. And the 9.9x multiple provides a grounded return estimate without assuming significant multiple expansion.
Gradual debt reduction and margin improvement could drive a re-rating toward 11x to 13x over time. So the 9.9x assumption is conservative but appropriate for where the company sits today. Management’s credit agreement amendment in April 2026 signals active balance sheet management that could support deleveraging over the forecast period.

What Happens If Things Go Better or Worse?
Different scenarios for AMTM stock through 2030 show varied outcomes based on contract win rates and margin recovery progress (these are estimates, not guaranteed returns):
- Low Case: Government budget pressures slow contract awards, and margins stay compressed near current levels → 1.9% annual returns
- Mid Case: New government contracts convert steadily, and margins gradually improve toward 5% → 4.5% annual returns
- High Case: Strong international wins and faster cost discipline accelerate margin recovery and valuation → 6.8% annual returns
Going forward, Amentum’s stock will be driven by whether the company can convert its contract backlog into revenue growth while improving margins from today’s low single-digit levels. The Q2 2026 earnings report on May 12 is the next key checkpoint, and investors will watch for updates to full-year guidance and debt reduction progress.
Even in the mid case, annual returns sit near 4.5%, which is below the 10% threshold many investors target, so AMTM may appeal primarily to patient investors with a longer time horizon.
