Amentum Holdings Signals Steady Growth and Strong Backlog

Amentum Holdings, Inc. ((AMTM)) has held its Q2 earnings call. Read on for the main highlights of the call.

Amentum Holdings’ latest earnings call struck an upbeat tone, with management emphasizing steady growth, margin expansion and strengthening cash generation. Executives highlighted robust demand across critical digital infrastructure, nuclear and space markets, while downplaying identifiable headwinds such as program ramps, JV transitions and a modest NASA-related impact in fiscal 2027.

Revenue Growth and Improving Profitability

Amentum reported second-quarter revenue of $3.5 billion, reflecting normalized year-over-year growth of about 3% after adjusting for divestitures. Adjusted EBITDA reached $275 million with a 7.9% margin, up roughly 20 basis points, while adjusted diluted EPS climbed 13% to $0.60, underscoring disciplined cost control.

Bookings Strength and Expanding Backlog

Net bookings came in at $4.0 billion, and trailing-12-month book-to-bill stood at 1.2x, or 1.3x including joint ventures on an imputed basis. Backlog ended the quarter near $48 billion, up around 7% year-over-year, with funded backlog of $6.9 billion rising roughly 20%, supported by over $20 billion in first-half submissions and $26 billion in proposals awaiting award.

Free Cash Flow Rebounds in the Quarter

Free cash flow rebounded to $220 million in the quarter as collections normalized following earlier timing issues. First-half free cash flow of $78 million still reflects seasonality, but management reiterated full-year free cash flow guidance of $525–$575 million, pointing to strong expected fourth-quarter collections.

Refinancing Lowers Debt Costs and Adds Flexibility

After quarter-end, Amentum refinanced with a new $1.4 billion Term Loan A to pay down and reprice its Term Loan B and expanded its revolver to $1.0 billion. Combined with a Moody’s upgrade, these actions reduced the weighted average cost of debt by about 50 basis points and support a net leverage target below 3x by year-end.

Digital Solutions Drives Top-Line Acceleration

Digital Solutions delivered revenue of $1.5 billion, up roughly 10% year-over-year, powered by ramps in critical digital infrastructure and space systems contracts. Management pointed to ongoing strength in digital and space end markets, presenting this segment as a key growth engine despite current margin pressure.

Global Engineering Solutions Margin Expansion

Global Engineering Solutions generated $2.0 billion of revenue with adjusted EBITDA of $170 million and an 8.5% margin. That margin is up about 100 basis points from a year ago, driven by a richer mix of fixed-price work, higher joint venture equity income and continuing cost synergy benefits.

Strategic Contract Wins Underpin Growth

The quarter featured several high-profile awards, including a 14-year, $406 million small modular reactor contract in the U.K. through an Amentum-led joint venture. Additional wins included a European Commission decommissioning and waste deal, a major CALFIRE aviation contract, over $300 million in intelligence awards and more than $600 million in critical digital infrastructure awards tied to telecom and AI data centers.

Positioning in High-Growth CDI, Nuclear and Space Markets

Management underscored sizable tailwinds in critical digital infrastructure, noting data center demand growing near 29% annually and edge infrastructure expected to grow about 36% annually through 2030. Overall, Amentum estimates more than $4 billion of annual revenue already exposed to fast-growing CDI, nuclear and space markets, typically carrying attractive margins.

Digital Solutions Margin Pressure During Ramps

Despite strong revenue, Digital Solutions saw slightly lower adjusted EBITDA versus last year, reflecting the impact of a fiscal 2025 divestiture and the timing of new program starts. Margins on space and CDI programs are beginning at modest levels due to ramp-up costs and tougher prior-year comparisons, and management cautioned that near-term margins may remain subdued.

JV Transitions, Divestitures Temper Reported Growth

Global Engineering Solutions and overall company growth were affected by joint venture transitions and a previously executed divestiture. The planned ramp-down of certain legacy programs also weighed on reported revenue, partially offsetting gains from newer, higher-margin projects.

Cash Flow Seasonality and Working Capital Sensitivity

First-half free cash flow of $78 million, versus $220 million in the second quarter alone, highlighted the company’s pronounced cash seasonality. Management stressed that timing of collections and working capital swings can distort interim figures, but they remain confident that the bulk of cash will arrive in the fourth quarter.

NASA Directive Adds Modest 2027 Headwind

A recent NASA workforce directive to incrementally in-source specific expertise is expected to reduce Amentum’s fiscal 2027 revenue by about 1%. The company anticipates a smaller impact on EBITDA and framed the change as a modest, customer-specific headwind that does not alter its broader growth trajectory.

Award Timing and Program Write-Up Volatility

Roughly $26 billion of proposals are sitting in evaluation, and management acknowledged that timing of adjudications represents a key execution risk. In addition, the pace of program write-ups can vary by quarter, creating some lumpiness in margins and reported earnings despite steady underlying operations.

Guidance and Forward-Looking Outlook

Amentum reaffirmed its fiscal 2026 outlook for revenue of $13.95–$14.30 billion, adjusted EBITDA of $1.10–$1.14 billion, adjusted EPS of $2.25–$2.45 and free cash flow of $525–$575 million. With about 97% of revenue expected from existing or recompete work, a backlog near $48 billion, a 1.2x book-to-bill and lower debt costs, management targets net leverage in the high-2s and 10%-plus free cash flow growth through fiscal 2028.

Amentum’s earnings call painted a picture of a company executing well while leaning into powerful secular trends in digital infrastructure, nuclear and space. Investors heard a story of disciplined growth, expanding margins and improving cash generation, with manageable risks around award timing, NASA exposure and program ramp dynamics that appear outweighed by the company’s growing backlog and strengthened balance sheet.
