NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 — Basis of Presentation

Amentum Holdings, Inc. (collectively with its subsidiaries, “we,” “us,” “our,” “Amentum,” or the “Company”) is a global advanced engineering and technology solutions provider to a broad base of U.S. and allied government agencies, supporting programs of critical national importance across energy and environmental, intelligence, space, defense, civilian and commercial end-markets. We offer a broad reach of capabilities including intelligence and counter threat solutions, data fusion and analytics, engineering and integration, environmental solutions, advanced test, training and readiness, and citizen solutions. As a leading provider of differentiated technology solutions, we have built a repertoire of deep customer knowledge, enabling us to engage our customers across multiple capabilities and markets.

During the ~~three~~first ~~months~~quarter ~~ended~~of ~~December 27,~~fiscal ~~2024~~year 2025, we announced the realignment of our reporting structure, which resulted in the identification of two reportable segments: Digital Solutions (“DS”) and Global Engineering Solutions (“GES”). The ~~Digital~~DS ~~Solutions~~ segment provides advanced digital and data-driven solutions including intelligence analytics, space system development, cybersecurity, and next generation IT across the federal government and commercial clients. The ~~Global~~GES ~~Engineering Solutions~~ segment provides large-scale environmental remediation, clean energy, platform engineering, sustainment and supply chain management across all seven continents for the U.S. government and allied nations. As a result of this change, prior year segment disclosures have been recast to reflect the current reportable segment structure.

On September 27, 2024, the spin-off of the Jacobs Solutions Inc. (“Jacobs”) Critical Mission Solutions business and portions of the Jacobs Divergent Solutions business (and, together with the Critical Mission Solutions business, referred to as the “CMS Business” or “CMS”) merged with Amentum Parent Holdings LLC (collectively, the “Transaction”) with the surviving entity renamed Amentum Holdings, Inc.

Amentum Parent Holdings LLC is considered the Company’s predecessor, and the historical financial statements of Amentum Parent Holdings LLC prior to September 27, 2024 are reflected in this Quarterly Report on Form 10-Q as the Company’s historical financial statements. Accordingly, the financial results of the Company prior to September 27, 2024 do not include the financial results of CMS, and current and future results will not be comparable to historical results.

The accompanying unaudited condensed consolidated financial statements of the Company include the assets, liabilities, results of operations, comprehensive income (loss) and cash flows for the Company, including its wholly-owned subsidiaries and joint ventures that are majority-owned or otherwise controlled by the Company. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted, although the Company believes that the disclosures made are adequate to make the information presented not misleading. All intercompany transactions and balances have been eliminated in consolidation.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments and reclassifications (all of which are of a normal, recurring nature) that are necessary for the fair presentation of the periods presented. It is suggested that these unaudited condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s latest annual report for the fiscal year ended September 27, 2024. The results of operations for the three and six months ended ~~December~~March 2728, ~~2024~~2025 are not necessarily indicative of the results to be expected for any subsequent interim period or for the full fiscal year.

Note 2 — Recent Accounting Pronouncements

Accounting Standards Updates Issued but Not Yet Adopted

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements. This update requires disclosure of significant segment expenses and other segment items in annual and interim periods. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The amendment requires retrospective application to all prior periods presented in the financial statements, and early adoption is permitted. We are currently evaluating the impacts of the new standard on our consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance transparency and usefulness of income tax disclosures. This update requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, and may be applied on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impacts of the new standard on our ~~consolidated~~ financial ~~statements~~statement disclosures.

Note 3 — Acquisition

On September 27, 2024, the Company completed its merger with CMS, a leading provider of mission-critical, technology-driven services in government and commercial markets, in a Reverse Morris Trust transaction. Immediately following the Transaction, the Company had approximately 243 million issued and outstanding shares of common stock, of which Jacobs and its shareholders (“CMS Shareholders”) owned 58.5% of the issued and outstanding shares of common stock, and Amentum Joint Venture LP, our previous parent company (“AJVLP” and “Amentum Equityholder”) owned 37.0%. Subsequently, Amentum Equityholder distributed its shares of our common stock to certain parties (collectively, “Sponsor Stockholder”). Further, 4.5% of the issued and outstanding shares of common stock ~~have~~was ~~been~~ placed in escrow at the merger date, to be released and delivered in the future to ~~Jacobs~~CMS ~~and~~Shareholders ~~its shareholders~~ or to ~~Sponsor~~Amentum ~~Stockholder~~Equityholder, depending on the achievement of certain fiscal year 2024 targets by the CMS Business (“Additional Merger Consideration”). ~~The~~In ~~final~~March ~~determination~~2025, ofthe ~~this~~Company and Jacobs finalized the Additional Merger Consideration isand ~~expected~~released all 4.5% of the issued and outstanding shares of common stock out of escrow with 3.5% of the issued and outstanding shares released to beCMS ~~completed~~Shareholders ~~during~~and the ~~measurement~~remaining ~~period~~1.0% of issued and outstanding shares to the Sponsor Stockholder.

(1) Represents the fair value of equity consideration received by CMS Shareholders to provide 58.5% ownership in the Company.

(2) Represents the Additional Equity Consideration which was finalized in March 2025. The balance reflects a decrease in equity consideration issued to CMS Shareholders following a resolution to release an additional 1.0% of the issued and outstanding shares of Amentum common stock back to Sponsor Stockholder. This balance is presented at fair value based on the acquisition-date share price and is included in the total purchase consideration in accordance with ASC 805.

(3) Reflects a $70 million cash payment made based on the final net working capital position. This payment was made in the third quarter of fiscal year 2025 and is included in the total purchase consideration in accordance with ASC 805, as it represents an obligation attributable to pre-acquisition activities.

(4) Represents other immaterial adjustments, including a) estimated equity consideration related to pre-combination share-based compensation awards, b) the settlement of CMS transaction costs paid by Amentum, and c) the removal of consideration related to the acquisition of non-controlling interests.

(5) Prior to the Transaction, we held a non-controlling interest in a joint venture of 50% which was accounted for under the equity method of accounting, with the remaining 40% held by the CMS Business and 10% held by an unrelated third party. As a result of the Transaction, the Company gained a controlling financial interest in the joint venture and it became a consolidated joint venture of the Company. This joint venture acquisition was accounted for as a business combination achieved in stages. Our pre-existing equity method investment in the joint venture was remeasured at an acquisition date fair value of $170 million by using a discounted cash flow model based on estimated future revenues, margins and discount rates, among other variables and estimates. Additionally, as of the acquisition date, the Company had a payable to the joint venture with a fair value of $1 million that was settled in connection with the acquisition.

The Transaction was accounted for as a business combination. The Company assessed the fair value of the identifiable intangible assets including customer relationships and backlog, which were valued using the excess earnings method of the income approach. This method requires several judgments and assumptions to determine the fair value of the intangible assets including expected future cash flows, weighted-average cost of capital, discount rates, useful lives of assets and expected long-term growth rates. The goodwill recognized was attributable to the synergies expected to be achieved by combining the businesses of Amentum and CMS, expected future contracts and the acquired workforce. The goodwill is partially deductible for tax purposes.

The purchase price was allocated, on a preliminary basis, to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, with the excess purchase consideration recorded as goodwill. The Company is still evaluating the determination of fair values allocated to various assets and liabilities, including, but not limited to, intangible assets, accounts receivable, other current assets, property and equipment, equity method investments and joint ventures, other long-term assets, income taxes, deferred taxes, accounts payables, other current liabilities, contract liabilities, other long-term liabilities, non-controlling interests, additional merger consideration and goodwill. The allocation of the purchase price is preliminary and subject to change as the Company continues to obtain and assess relevant information that existed as of the acquisition date, including but not limited to, information pertaining to CMS’ legal proceedings, reserves, income taxes, contracts with customers, and pre-acquisition contingencies. Additionally, in connection and in accordance with the terms of the spin-off, prior to the spin-off and Transaction, CMS provided a cash payment to Jacobs of approximately $911 million, after adjustments based on the levels of cash, debt and working capital in the CMS Business, which is subject to final settlement between the parties, as set forth in the Merger Agreement, and may result in changes to the purchase price allocation. The Company expects to have sufficient information available to resolve these items within one year of the CMS acquisition date. During the three months ended December 27, 2024, the Company made fair value adjustments which increased goodwill and other current liabilities by $32 million and $20 million, respectively, and decreased accounts receivable and deferred tax liabilities by $22 million and $10 ~~million, respectively.~~

The estimated fair value of acquired backlog of $275 million is amortized on an accelerated basis over approximately 1 year and the estimated fair value of customer relationship intangible assets of $1,555 million is amortized on an accelerated basis over approximately 14 years. The fair value attributed to these intangible assets acquired was based on assumptions and other information compiled by management, including independent valuations that utilized established valuation techniques, and thus represents a Level 3 fair value measurement. The income approach was primarily used to value the intangible assets, consisting primarily of acquired program and contract intangibles and backlog. The income approach indicates value for an asset based on the present value of cash flow projected to be generated by the asset. Projected cash flow is discounted at a rate of return that reflects the relative risk of achieving the cash flow and the time value of money.

As amended, the Company’s senior secured credit facility (the “Credit Facility”) consists of a seven year, $3,750 million term facility (“Term Loan”) and a five year, $850 million revolving facility (“Revolver”), including a $200 million letter of credit subfacility and a $100 million swingline subfacility.

The interest rates applicable to the Term Loan are floating interest rates equal to an Alternate Base Rate or Adjusted Term Secured Overnight Financing Rate plus an applicable margin based upon net leverage ratio. The Term Loan matures on September 27, 2031 and requires quarterly principal amortization payments of $9 million commencing March 31, 2025 with the remainder of the principal thereunder being due at maturity. The Revolver matures on September 27, 2029.

As of ~~December~~March 2728, ~~2024~~2025 and September 27, 2024, the available borrowing capacity under the Credit Facility was $~~788~~775 million and $808 million, respectively, and included $6275 million and $42 million, respectively, in issued letters of credit. As of ~~December~~March 2728, ~~2024~~2025 and September 27, 2024, there were no amounts borrowed under the Revolver.

In August 2024, the Company completed an offering of $1,000 million in aggregate principal amount of 7.250% senior notes due August 1, 2032 (the “Senior Notes”). Interest is payable on February 1 and August 1 of each year, ~~commencing~~which commenced on February 1, 2025.

The Credit Facility and the Senior Notes are guaranteed by substantially all of our wholly owned material domestic restricted subsidiaries, subject to customary exceptions set forth in the credit agreement and indenture, respectively.

Each of the credit agreement and indenture requires us to comply with certain representations and warranties, customary affirmative and negative covenants and, in the case of the Revolver, under certain circumstances, a financial covenant. We were in compliance with all covenants as of ~~December~~March 2728, ~~2024~~2025.

Cash Flow Hedges

The Company utilizes derivative financial instruments to manage interest rate risk related to its variable rate debt. The Company’s objective is to manage its exposure to interest rate movements and reduce volatility of interest expense. The Company entered into several interest rate swaps with an aggregate notional value of $1.9 billion that were designated as cash flow hedges, in which the Company will pay at the fixed rate and receive payment at a floating rate indexed to the three-month term SOFR through maturity. The swaps mature at various dates through January 31, 2027. The change in fair value of the interest rate swaps is presented within accumulated other comprehensive income on our consolidated balance sheet and subsequently reclassified into interest expense and other, net on our consolidated statements of income and comprehensive loss in the period when the hedged transaction affects earnings.

Note 10 — Joint Ventures

The Company’s joint ventures provide services to customers including program management and operations and maintenance services. Joint ventures, the combination of two or more partners, are generally formed for a specific project. Management of the joint venture is typically controlled by a joint venture executive committee, comprised of representatives from the joint venture partners. The joint venture executive committee normally provides management oversight and controls decisions which could have a significant impact on the joint venture.

We account for joint ventures in accordance with ASC 810, Consolidation. The Company analyzes its joint ventures and classifies them as either:

14•a Variable Interest Entity (“VIE”) that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or

•a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or

•a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest.

The following table presents selected financial information for our consolidated joint ventures that are VIEs as of ~~December~~March 2728, ~~2024~~2025 and September 27, 2024:

The following table presents selected financial information for our consolidated joint ventures that are VIEs for the three and six months ended March 28, 2025 and March 29, 2024:

The Company has an ownership share in approximately 25 active joint ventures that are accounted for as equity method investments and the Company’s ownership percentages generally range from 10% to 51%. Related party receivables due from our equity method investments were $35 million and $37 million as of December 27, 2024 and September 27, 2024, respectively. These receivables are a result of items purchased and services rendered by us on behalf of our equity method investments. We have assessed these receivables as having minimal collection risk based on our historic experience with these joint ventures and our inherent influence through our ownership interest. The related party revenues earned from our equity method investments was $44 million and $28 million for the three months ended December 27, 2024 and December 29, 2023, respectively.

Note 12 — Segment Information

In the first quarter of fiscal year 2025, we amended our organizational structure, which resulted in the identification of two reportable segments: Digital Solutions (“DS”) and Global Engineering Solutions (“GES”).

The ~~Digital~~DS ~~Solutions~~ segment provides advanced digital and data-driven solutions including intelligence analytics, space system development, cybersecurity, and next generation IT across the federal government and commercial clients.

The ~~Global~~GES ~~Engineering Solutions~~ segment provides large-scale environmental remediation, clean energy, platform engineering, sustainment and supply chain management across all seven continents for the U.S. government and allied nations.

The presentation of financial results as two reportable segments is consistent with the way the Company operates its business and the manner in which our chief operating decision maker (“CODM”), currently our Chief Executive Officer, manages the operations of the Company for purposes of allocating resources and assessing performance. The CODM evaluates the performance of our segments based on revenues and Adjusted EBITDA. Prior year performance measures have been recast to reflect the current reportable segment structure.

The Company’s segment revenues were as follows:

			Three months ended
	Three Months Ended								Six Months Ended
			December 27, 2024												December 29, 2023
(Amounts in millions)	March 28, 2025				March 29, 2024				March 28, 2025				March 29, 2024
(Amounts in millions)			DS				GES				Total				DS		GES		Total
DS	$	1,340			$	471			$	2,626			$	930
Revenues			$	1,286			$	2,130			$	3,416			$	459	$	1,524	$	1,983
GES	2,151				1,580				4,281				3,104
Total	$	3,491			$	2,051			$	6,907			$	4,034

Adjusted EBITDA is most comparable to net income (loss) attributable to common shareholders prepared based on GAAP. The Company defines Adjusted EBITDA as net income (loss) attributable to common shareholders adjusted for interest expense and other, net, provision for income taxes, depreciation and amortization, and certain discrete items that are not considered in the evaluation of ongoing operating performance. These discrete items include acquisition, transaction, and integration costs, non-cash gains and losses, loss on extinguishment of debt, utilization of certain fair market value adjustments assigned in purchase accounting, and share-based compensation. While we believe Adjusted EBITDA is a useful metric in evaluating operating performance by allowing better evaluation of underlying segment performance and better period-to-period comparability, it is not a metric defined by GAAP and may not be comparable to non-GAAP metrics presented by other companies.

The following table reconciles segment Adjusted EBITDA to net income (loss) attributable to common shareholders:


	Three months ended				Six months ended

(1) Represents acquisition, transaction and integration costs, including severance, retention, and other adjustments related to acquisition and integration activities.

(2) Represents the periodic utilization of the fair market value adjustments assigned to certain equity method investments and non-controlling interests based on the remaining period of performance for the related contract.

(3) Represents non-cash compensation expenses recognized for share based arrangements.

Asset information by segment is not a key measure of performance used by the CODM.

Note 13 — Earnings (Loss) Per Share

For the three months ended December 29, 2023, the Company retrospectively adjusted the weighted average shares used in determining loss per share to reflect the conversion of the ownership interests of Amentum Parent Holdings LLC held by AJVLP that converted into 90,021,804 shares of the Company’s common stock at Transaction close. There were no anti-dilutive shares for the three months ended December 29, 2023.19

For the three and six months ended March 29, 2024, the Company retrospectively adjusted the weighted average shares used in determining loss per share to reflect the conversion of the ownership interests of Amentum Parent Holdings LLC held by AJVLP that converted into 90,021,804 shares of the Company’s common stock at Transaction close. There were no anti-dilutive shares for the three and six months ended March 29, 2024.

Basic and diluted earnings (loss) per share are computed as follows (in millions, except per share data):

Note 14 — Legal Proceedings and Commitments and Contingencies

The Company is involved in various claims, disputes and administrative proceedings arising in the normal course of business. Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that an unfavorable result and/or liability will be incurred and the cost of the unfavorable result or liability can be reasonably estimated. Management is of the opinion that any liability or loss associated with such matters, either individually or in the aggregate, will not have a material adverse effect on the Company’s operations and liquidity.

Payments to the Company on cost-plus-fee contracts are provisional and are subject to adjustments upon audit by the Defense Contract Audit Agency (“DCAA”). In management’s opinion, audit adjustments that may result from audits not yet completed or started are not expected to have a material adverse effect on the Company’s operations and liquidity.

Pending Litigation and Claims

Department of Energy Claims

In January 2020, the Company purchased assets and assumed liabilities associated with AECOM Energy & Construction, Inc. (the “Acquired Affiliate”) from AECOM (the “Seller”). At the time of the acquisition, the Acquired Affiliate had pending claims against the U.S. Department of Energy (“DOE”) related to a contract performed prior to the acquisition. The Company and the Seller agreed that all future claim recoveries and costs with the DOE would be split 10% to the Company and 90% to the Seller. Following the DOE’s denial of the claims, on December 20, 2020, the Acquired Affiliate filed an appeal of these decisions in the U.S. Court of Federal Claims. The Company has estimated and recorded $138 million within other long-term assets on the balance sheet and $125 million within other long-term liabilities on the balance sheet representing the Company’s payable to the Seller related to this matter. No changes to these amounts have been recorded since the acquisition. The Company intends to cooperate with the Seller in the pursuit of all claimed amounts but can provide no certainty that the Company will recover the claims. The Company does not believe any additional incurred claims or costs related to this matter will have a material adverse effect on the Company’s results of operations.

U.S. Government Investigations

We primarily sell our services to the U.S. Government. These contracts are subject to extensive legal and regulatory requirements, and we are occasionally the subject of investigations by various agencies of the U.S. Government who investigate whether our operations are being conducted in accordance with these requirements. Such investigations could result in administrative, civil or criminal liabilities, including repayments, fines or penalties being imposed on us, or could lead to suspension or debarment from future U.S. Government contracting. U.S. Government investigations often take years to complete and may result in adverse action against us. Any adverse actions arising from such matters could have a material effect on our ability to invoice and receive timely payment on our contracts, perform contracts or compete for contracts with the U.S. Government and could have a material effect on our operating performance. There are currently no investigations that are expected to have a material impact on our results of operations.

Note 15 — Subsequent Event

Divestiture of Rapid Solutions

On April 23, 2025, we entered into a definitive agreement to sell our hardware and product business, Rapid Solutions, to Lockheed Martin for a purchase price of $360 million in cash, subject to regulatory approvals and customary closing conditions. The planned sale of the Rapid Solutions business is not classified as discontinued operations as it does not represent a strategic shift in our business.

Overview

We are a global advanced engineering and technology solutions provider to a broad base of U.S. and allied government agencies, supporting programs of critical national importance across energy and environmental, intelligence, space, defense, civilian and commercial end-markets. We offer a broad reach of capabilities including environment and climate sustainability, intelligence and counter threat solutions, data fusion and analytics, engineering and integration, advanced test, training and readiness, and citizen solutions. As a leading provider of differentiated technology solutions, we have built a repertoire of deep customer knowledge, enabling us to engage our customers across multiple capabilities and markets. Underpinned by a strong culture of ethics, safety and inclusivity, Amentum is committed to operational excellence and successful execution.

In fiscal year 2024, we completed our merger with Jacobs Solutions Inc. (“Jacobs”) Critical Mission Solutions business and portions of the Jacobs Divergent Solutions business (and, together with the Critical Mission Solutions business, referred to as the “CMS Business” or “CMS”), a leading provider of mission-critical, technology-driven services in government and commercial markets.

We conduct our business activities and report financial results as two business segments: Digital Solutions (“DS”) and Global Engineering Solutions (“GES”). ~~Digital~~DS ~~Solutions~~ provides advanced digital and data-driven solutions including intelligence analytics, space system development, cybersecurity, and next generation IT across the federal government and commercial clients. GES provides large-scale environmental remediation, clean energy, platform engineering, sustainment and supply chain management across all 7 continents for the U.S. government and allied nations.

clients. Global Engineering Solutions provides large-scale environmental remediation, clean energy, platform engineering, sustainment and supply chain management across all 7 continents for the U.S. government and allied nations.

Budgetary Environment

In fiscal year 2024, we generated approximately 90% of our revenues from contracts with the U.S. federal government, either as a prime contractor or a subcontractor to other contractors engaged in work for the U.S. federal government. We carefully follow the U.S. federal budget, legislative and contracting trends and activities and evolve our strategies accordingly.

The U.S. federal government fiscal year (“GFY”) ~~2024~~2025 appropriations bill was passed in March ~~2024~~2025. The final bill ~~was~~provided ~~consistent~~a ~~with~~1% ~~the~~increase ~~Fiscal~~for ~~Responsibility~~defense ~~Act~~discretionary ofspending ~~June~~to ~~2023.~~$892 ~~Defense~~billion and a 1% increase in non-defense discretionary spending ~~saw~~to a$708 3billion.3% ~~increase~~The GFY 2026 “skinny” budget request was submitted to Congress on May 2, 2025, and if enacted, would maintain defense discretionary spending at $~~886~~892 billion, ~~while~~and reduce non-defense discretionary spending ~~remained~~by ~~flat~~approximately at21% to $~~703~~557 billion. Additionally, the skinny budget request assumes an increase in defense spending based on the defense reconciliation legislation currently pending in Congress, which would result in total GFY 2026 defense spending of $1.01 trillion, an increase of 13% from the GFY 2025 enacted level.

President Trump was inaugurated in January 2025 and the new administration’s GFY 2026 budget request is expected to be submitted to Congress in April 2025. Under the Trump administration, the new Department of Government Efficiency was created to propose savings through improvements to technology and increases to productivity in the federal workforce; we continue to monitor the actions of the new administration which could result in a change to budgetary priorities or impact federal government procurement timing. Decreases in, or delays in approving, the federal government’s budget, decreases in government spending on the types of programs that we support, delays in government contract awards, and pauses on government contracts on which we are currently performing could have an adverse impact on our business. For further information, please see Item 1A., “Risk Factors,” in our Annual Report on Form 10-K for the fiscal year ended September 27, 2024.

currently performing could have an adverse impact on our business. For further information, please see Part I. Item 1A. Risk Factors in our Fiscal Year 2024 Form 10-K.

While we view the budget environment as constructive and believe core funding sources for our primary customer-based markets will continue to experience bipartisan tailwinds, there can be no certainty about the level of funding for any particular GFY or that appropriations bills will be passed in a timely manner. During those periods of time when appropriations bills have not been passed and signed into law, government agencies operate under a continuing resolution (“CR”), a temporary measure allowing the government to continue operations at prior year funding levels. Depending on their scope, duration, and other factors, CRs can negatively impact our business due to delays in new program starts, delays in contract awards decisions, and other factors.

Additionally, the U.S. Government is in the process of, or has announced its intent to, increase current tariffs, impose additional tariffs, and expand tariffs on goods imported from various countries into the United States. The tariffs that have been enacted by the U.S. or other countries did not materially impact our business or financial results for the three months ended March 28, 2025. We are currently evaluating the potential future impacts of the announced tariffs on our business and financial condition.

For a discussion of risks related to tariffs and other trade policy issues, see Part II. Item 1A. Risk Factors in this Report and Part I. Item 1A. Risk Factors in our Fiscal Year 2024 Form 10-K.

Market Environment

We believe our scale, breadth of capabilities, and depth of experience give us a robust understanding of our customers’ evolving needs. Given our portfolio diversity, we believe our total addressable market, and associated growth rate, is sufficient to support our strategic growth plans.

We believe Amentum’s capabilities are strategically aligned to well-funded, long-term priorities for the federal government, allied nations, and commercial customers. Specifically, we believe we are well positioned to continue to win new business driven by the following trends in our addressable market:

•Increasing demand for outsourced services and solutions with federal government customers;

•Increased global demand for clean and environmentally sustainable solutions;

•Increased spending on government-wide modernization priorities;

•Increasing government focus on near-peer competitors and other nation state threats;

•Increasing discretionary spending for Indo-Pacific regional activities and initiatives; and

•Increased investment in advanced technologies (e.g., hypersonics, microelectronics, unmanned, electromagnetic spectrum).

Revenues — The increase in revenues was primarily attributable to revenues from the merger with CMS.

Cost of revenues — The increase in cost of revenues was primarily attributable to the increased revenues volume from the merger with CMS. As a percentage of revenues, cost of revenues was 89.4% for the three months ended December 27, 2024 compared to 90.2% for the three months ended December 29, 2023, respectively.22

Selling, general, and administrative expenses (“SG&A”) — The increase in SG&A was primarily attributable to the merger with CMS. SG&A as a percentage of revenues increased to 4.2% for the three months ended March 28, 2025 from 3.5% for the three months ended March 29, 2024 primarily due to the merger with CMS and an increase in acquisition, transaction and integration costs.

Amortization of intangibles — Amortization of intangibles primarily relates to the amortization of our backlog and customer relationship intangible assets, which increased due to the merger with CMS.

Equity earnings of non-consolidated subsidiaries — Equity earnings of non-consolidated subsidiaries include our proportionate share of the income from equity method investments and increased due to non-consolidated subsidiaries obtained in the merger with CMS, partially offset by the utilization of fair market value adjustments assigned to certain equity method investments based on the remaining period of performance for the related contract.

Interest expense and other, net — The decrease in interest expense and other, net was primarily due to the reduction to our term loan principal balance as compared to the three months ended ~~December~~March 29, ~~2023~~2024 combined with a decrease in interest rates, partially offset by the interest incurred on our Senior Notes during the three months ended ~~December~~March 2728, ~~2024~~2025.

Provision for income taxes — The effective tax rate for the three months ended ~~December~~March 2728, ~~2024~~2025 was 5391.37%, as compared to (5690.09)% for the three months ended ~~December~~March 29, ~~2023~~2024. The change in the effective tax rate was primarily due to the recognition of a valuation allowance against a disallowed interest expense deferred tax asset relative to income (loss) before income taxes in the respective period.

Net income (loss) attributable to non-controlling interests — Net income (loss) attributable to non-controlling interests ~~include~~includes the utilization of fair market value adjustments assigned to certain non-controlling interests based on the remaining period of performance for the related contract partially offset by the minority interests in our consolidated joint ventures that are not wholly-owned~~, which increased due to the merger with CMS~~.

Our earnings and profitability may vary materially depending on changes in the proportionate amount of revenues derived from each type of contract. For a discussion of the types of contracts under which we generate revenues, see “Critical Accounting Policies” below. The following table summarizes revenues by contract type, as a percentage of revenues, for the periods presented:


	Three Months Ended				Six Months Ended
	March 28, 2025		March 29, 2024		March 28, 2025		March 29, 2024

Backlog

The Company's backlog represents the estimated amount of future revenues to be recognized under negotiated contracts. The Company’s backlog includes unexercised option years and excludes the value of task orders that may be awarded under multiple award indefinite delivery / indefinite quantity (“IDIQ”) vehicles until such task orders are issued.

The Company’s backlog is either funded or unfunded:

•Funded backlog represents contract value for which funding is appropriated less revenues previously recognized on the contract.

•Unfunded backlog represents estimated values that have the potential to be recognized as revenues from negotiated contracts for which funding has not been appropriated and from unexercised contract options.

As of ~~December~~March 2728, ~~2024~~2025, the Company had total backlog of $4544.28 billion, compared with $27.32 billion as of ~~December~~March 29, ~~2023~~2024, an increase of $17.96 billion primarily due to the merger with CMS. Funded backlog as of ~~December~~March 2728, ~~2024~~2025 was $65.68 billion.

There is no assurance that all backlog will result in future revenues being recognized, and the backlog balance is subject to increases or decreases based on the execution of new contracts, contract modifications or extensions, deobligations, early terminations, and other factors.

Effects of Inflation

Given the nature of our operations and contract type mix, we expect the impact of inflation on our business may be limited for some of our contracts. During the ~~three~~six months ended ~~December~~March 2728, ~~2024~~2025, 64% of our revenues was generated under cost-plus-fee type contracts that have limited inflation risk as they include provisions that adjust revenues to cover costs affected by inflation. The remainder of our revenues was generated under time-and-materials or fixed-price type contracts which we have historically been able to price in a manner that accommodates inflation and cost increases over the period of performance but changes in our expectations with respect to inflation rates or in the overall mix of our contract types could cause future results to differ substantially.

Liquidity and Capital Resources

Existing cash and cash equivalents and cash generated by operations are our primary sources of liquidity, as well as sales of receivables under our Master Accounts Receivable Purchase Agreement (“MARPA”) and available borrowing capacity under the revolving credit facility provided for in the senior secured credit facility (the “Credit Facility”).

The Credit Facility consists of a seven year, $3,750 million term facility (“Term Loan”) and a five year, $850 million revolving facility (“Revolver”), including a $200 million letter of credit subfacility and a $100.0 million swingline subfacility. The Revolver and the Term Loan mature on September 27, 2029 and September 27, 2031, respectively. The Term Loan requires quarterly principal amortization payments of $9 million commencing March 31, 2025 with the remainder of the principal thereunder being due at maturity. In August 2024, the Company also completed an offering of $1,000 million in aggregate principal amount of 7.250% senior notes due August 01, 2032 (the “Senior Notes”).

thereunder being due at maturity. In August 2024, the Company also completed an offering of $1,000 million in aggregate principal amount of 7.250% senior notes due August 1, 2032 (the “Senior Notes”).

The New Credit Facility and the Senior Notes are guaranteed by substantially all of our wholly owned material domestic restricted subsidiaries, subject to customary exceptions set forth in the credit agreement and indenture, respectively.

We believe that the combination of internally generated funds, available bank borrowings, and cash and cash equivalents on hand will provide the required liquidity and capital resources necessary to fund on-going operations, capital expenditures, scheduled principal and interest payments on our debt obligations, scheduled lease payments, and other working capital requirements over at least the next twelve months.

On April 23, 2025, we entered into a definitive agreement to sell our hardware and product business, Rapid Solutions, to Lockheed Martin for a purchase price of $360 million in cash, subject to regulatory approvals and customary closing conditions. Certain proceeds from the planned sale of the Rapid Solutions business are expected to be used to accelerate our debt reduction objectives.

Over the longer term, our ability to generate sufficient cash flows from operations necessary to fulfill the obligations under the Credit Facility, Senior Notes and any other indebtedness we may incur will depend on our future financial performance which could be affected by factors outside of our control, including worldwide economic and financial market conditions.

See “Note 6 — Sales of Receivables” and “Note 9 — Debt” of the notes to the condensed consolidated financial statements contained within this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Estimates

There have been no significant changes to the Company’s critical accounting policies as disclosed in our Annual Report on Form 10-K for the year ended September 27, 2024.

Recent Accounting Pronouncements

See “Note 2 — Recent Accounting Pronouncements” of the notes to the condensed consolidated financial statements contained within this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The remaining balance under the Term Loan, and any additional amounts that may be borrowed under the Revolver, are currently subject to interest rate fluctuations. We have the ability to manage these fluctuations in part through interest rate swaps on our variable rate debt. We have entered into floating-to-fixed interest rate swap agreements for an aggregate notional amount of $1.9 billion related to a portion of our variable rate debt. With every one percent fluctuation in the applicable interest rates, interest expense on our variable rate debt for the ~~three~~six months ended ~~December~~March 2728, ~~2024~~2025 would have fluctuated by approximately $919 million.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of such date.

Changes in Internal Control Over Financial Reporting

~~Other~~There ~~than changes related to the merger with the CMS Business, there~~ have been no changes in our internal control over financial reporting (as such term is defined in rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended ~~December~~March 2728, ~~2024~~2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

The information required with respect to this item is set forth in Note 14 — Legal Proceedings and Commitments and Contingencies in the Notes to Consolidated Financial Statements appearing under Part I, Item 1 of this Form 10-Q.

Item 1A. Risk Factors

~~There~~Other than as described below, there have been no material changes to our Risk Factors disclosed in the Company’s Form 10-K for the year end September 27, 2024.

Our business could be adversely impacted by changes in the U.S. Government’s approach to tariffs and other trade policies. As a result of major U.S. Government trade policy changes announced by President Trump on April 2, 2025, there is currently significant uncertainty with respect to tariffs that may impact our supply chain. New or increased tariffs for imports into the United States, as well as new or increased tariffs or trade bans imposed by other countries, could have an adverse effect on both our U.S. and international operations due to increased costs of materials, disruptions or delays in deliveries, and greater difficulty in planning and operating our business. While our business in the U.S. primarily provides labor services to our customers, some of our U.S. work involves providing goods that may be subject to tariffs. Our non-U.S. work could also be impacted by greater costs for goods sourced from the U.S. due to increased tariffs imposed by other countries. Although we plan to continue to monitor trade policy developments closely and to mitigate the adverse impacts of any changes where possible, we may not be able to fully mitigate such impacts in all situations.
