Amentum Q3 FY2026 earnings: Margin expansion offsets lower revenue

Amentum (NYSE: AMTM) reported fiscal Q3 2026 revenue of $3.490 billion, down 2% from $3.561 billion a year earlier, while diluted EPS rose to $0.27 from $0.04 for the quarter ended July 3, 2026. Profitability and cash generation improved despite the revenue decline: adjusted EBITDA increased 6% to $290 million, adjusted EBITDA margin reached 8.3%, and free cash flow rose 35% to $135 million.

Core financial results

Revenue declined because contract transitions from consolidated operations to unconsolidated joint ventures and fiscal 2025 divestitures created a 3% headwind. The ramp-up of new awards in critical digital infrastructure and space systems and technologies provided a partial offset.

Operating income rose 67%, supported by operating performance and lower intangible amortization. Lower interest expense also contributed to the increase in net income and EPS.

Adjusted EBITDA, adjusted EPS, and free cash flow are non-GAAP measures and should be considered alongside the company’s GAAP results.

Business and segment performance

The two segments moved in different directions. Digital Solutions generated modest revenue growth as new contracts ramped, while Global Engineering Solutions reported lower revenue because of joint-venture transitions, a prior-year divestiture, and expected program wind-downs.

Despite its revenue decline, Global Engineering Solutions increased adjusted EBITDA by 9%, reflecting margin initiatives, favorable contract mix, and program performance.

Digital Solutions benefited from critical digital infrastructure and space systems awards, partly offset by the fiscal 2025 divestiture of Rapid Solutions. Its adjusted EBITDA growth trailed revenue growth because the divestiture also affected segment profit.

Backlog and contract awards

Total backlog increased 8% to $48.2 billion from $44.6 billion, while funded backlog rose 10% to $6.2 billion. Quarterly book-to-bill was 1.1 times, and the last-12-month measure was 1.3 times, indicating that bookings remained above recognized revenue.

Major awards included more than $400 million related to advanced nuclear technologies, approximately $250 million for digital infrastructure, and more than $1 billion for U.S. and international defense work. The backlog also incorporated approximately $500 million associated with NASA’s COSMOS contract and a $974 million, 10-year CMOE II contract after related protests were resolved.

Revenue contracted while margins and earnings improved

The quarter’s central dynamic was the separation between revenue and profit. Revenue fell by $71 million, but operating income increased by $69 million. Adjusted EBITDA margin expanded by 60 basis points, showing that the improvement was not limited to GAAP accounting items.

Management attributed the adjusted margin increase to favorable contract mix, margin-expansion initiatives, and operating performance. On a GAAP basis, intangible amortization declined to $94 million from $118 million, while selling, general, and administrative expense fell to $122 million from $165 million. Equity earnings from non-consolidated subsidiaries also increased to $28 million from $18 million.

Interest expense and other items, net, decreased to $62 million from $88 million, further supporting earnings. This benefit was partly offset by a $16 million loss on debt extinguishment, compared with $3 million in the prior-year quarter.

Cash flow and balance sheet

Operating cash flow increased to $146 million, driven by cash earnings and working-capital management. The comparison also included one additional pay cycle relative to the prior-year quarter, creating a timing difference between the periods. After $11 million of capital expenditures, free cash flow was $135 million.

The stronger third-quarter cash result did not fully reverse the year-to-date decline. Operating cash flow for the first nine months of fiscal 2026 was $235 million, compared with $273 million in the corresponding prior-year period.

Amentum used $121 million in financing activities, primarily reflecting a $125 million voluntary principal payment on its Term Loan B and changes related to an amended credit facility. At quarter-end, the company held $459 million of cash and cash equivalents and had $3.875 billion of gross debt.

Fiscal 2026 guidance

Amentum reduced its full-year revenue range but improved its profitability outlook. The lower end of adjusted EBITDA guidance increased, both ends of adjusted EPS guidance moved higher, and free cash flow guidance was maintained.

The combination of lower revenue guidance and higher earnings guidance points to stronger expected profitability per dollar of revenue. However, maintaining the full-year free cash flow range while nine-month operating cash flow remained below the prior-year level makes fourth-quarter cash conversion an important operating consideration.

Management perspective

CEO John Heller said near-term conditions had affected the revenue outlook, but year-to-date operating performance allowed Amentum to raise adjusted EBITDA and adjusted EPS guidance. Management also emphasized business-development indicators, including recent nuclear energy wins and partnerships, as support for longer-term growth opportunities.

Risks investors should monitor

• Near-term revenue pressure: The lowered full-year revenue range indicates that joint-venture transitions, divestitures, and program wind-downs may continue to offset the ramp-up of new awards.
• Dependence on execution and contract mix: Recent profit growth relied partly on favorable mix, margin initiatives, and program performance. A reversal in these factors could pressure adjusted EBITDA margins.
• Cash conversion: Third-quarter free cash flow improved, but nine-month operating cash flow remained below the prior-year period while full-year free cash flow guidance was unchanged.
• Backlog conversion and government contracting: Amentum’s backlog is substantial, but revenue recognition depends on contract execution and timing. Government budget priorities, procurement rules, audits, and contract disputes can affect that conversion.
• Debt exposure: The voluntary term-loan payment reduced principal, but gross debt of $3.875 billion remained well above the company’s $459 million cash balance, leaving earnings and cash flow exposed to financing costs.

Summary

Amentum’s fiscal third quarter featured lower revenue but better profitability, supported by contract mix, operating execution, lower amortization, and reduced interest expense. Global Engineering Solutions was the clearest example of this pattern, producing higher adjusted EBITDA despite lower sales. The next areas to monitor are the causes of the reduced revenue outlook, fourth-quarter cash conversion, continued margin execution, and the pace at which the growing backlog becomes recognized revenue.
