Amentum Holdings, Inc.
Common Stock
This prospectus supplement relates to the offer and sale of 19,464,174 shares of our common stock, par value $0.01 per share (the “common stock”). All of these shares of our common stock are currently held by Jacobs Engineering Group, Inc. (“JEG”), a wholly-owned subsidiary of Jacobs Solutions Inc. (“Jacobs”). We are registering such shares under the terms of the Registration Rights Agreement by and between us and Jacobs, dated September 27, 2024 (the “Registration Rights Agreement”). We will not receive any of the proceeds from the sale of shares of our common stock under this prospectus supplement.
In connection with the sale of shares of our common stock pursuant to this prospectus supplement, JEG will exchange 19,464,174 shares of our common stock for certain indebtedness of JEG held by Bank of America, N.A. (the “Lender”), an affiliate of the selling shareholder identified in this prospectus supplement, pursuant to an exchange agreement expected to be entered into following the date of this prospectus supplement. We refer to this exchange between JEG and the Lender as the “debt-for-equity exchange,” and we refer to the Lender, in its role in the debt-for-equity exchange, as the “debt-for-equity exchange party”. The affiliate of the debt-for-equity exchange party, BofA Securities, Inc., as the selling shareholder in this offering, will then offer those shares of our common stock acquired pursuant to such debt-for-equity exchange in this offering for cash pursuant to this prospectus supplement and the accompanying prospectus. If consummated, the debt-for-equity exchange will occur on the settlement date of this offering, immediately prior to, and its consummation is a condition to, the settlement of the selling shareholder’s sale of the shares to the underwriters. As a result, the consummation of the debt-for-equity exchange is also a condition to the settlement of the underwriters’ sale of the shares to prospective investors. As a result of causing JEG to exchange the shares of our common stock with the Lender, as an affiliate of the selling shareholder, prior to the settlement of this offering, Jacobs may also be deemed to be a selling shareholder in this offering solely for U.S. federal securities law purposes. See “Selling Shareholder” and “Underwriting (Conflicts of Interest).”
Our common stock is listed on the New York Stock Exchange (the “NYSE”) under the symbol “AMTM”. On March 7, 2025, the last sale price of shares as reported on the NYSE was $19.99 per share.
In reviewing this prospectus supplement, you should carefully consider the matters described under the caption “Risk Factors” beginning on page 5 of the accompanying prospectus, as well as the risk factors and other information contained in our Annual Report on Form 10-K for the year ended September 27, 2024 (our “2024 Form 10-K”) and our Quarterly Report on Form 10-Q for the quarter ended December 27, 2024 (our “First Quarter 2025 Form 10-Q”), which are incorporated by reference into this prospectus supplement.

INFORMATION RELATING TO FORWARD-LOOKING STATEMENTS
Certain information included or incorporated by reference in this prospectus supplement or the accompanying prospectus, and other written or oral statements that we make from time to time, may not address historical facts and, therefore, could be interpreted to be “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995 and other federal securities laws.

PROSPECTUS SUPPLEMENT SUMMARY
This summary contains basic information about us and this offering. Because it is a summary, it does not contain all of the information that you should consider before investing. Before you decide to invest in our common stock, you should carefully read this entire prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein, including the sections entitled “Risk Factors” and “Information Relating to Forward-Looking Statements” in this prospectus supplement and the accompanying prospectus, any free writing prospectus prepared by or on behalf of us that we have referred to you, the sections entitled “Item 1A. Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2024 Form 10-K and our First Quarter 2025 Form 10-Q, which are incorporated by reference herein, and the financial statements incorporated by reference herein.
Company Overview
Amentum 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.
Our history as a trusted partner to the U.S. federal government and our advanced engineering and technology expertise enable us to lead and support our customers’ most complex programs. Our broad capabilities support technology-driven, full mission lifecycle solutions that align with modernization priorities for a wide array of customers. We believe our scale and breadth of capabilities position us well in the marketplace as our customers’ requirements increasingly necessitate a full lifecycle partner equipped with next-generation engineering solutions to solve their most complex challenges.
Our workforce of more than 53,000 continues to be rooted in a strong purpose-driven culture. Our mission-oriented and highly skilled personnel enable us to serve a diverse range of requirements for our customers. In the U.S., these customers include the Department of Energy (“DOE”), the Intelligence Community (consisting of the National Intelligence Program and the Military Intelligence Program), the Department of Defense (“DOD”), the National Aeronautics and Space Administration (“NASA”), and the Department of Homeland Security (“DHS”) as well as other government and certain commercial customers. We are also well-positioned internationally with employees across approximately 80 countries, supporting international customers and contracts in regions with growing mission demand, such as Europe and the Indo-Pacific, and with key allied government agencies, including the U.K. Ministry of Defence, the U.K. Nuclear Decommissioning Authority and the Australian Department of Defence. We support these customers by providing solutions to pressing challenges, from energy transition and environmental solutions to cybersecurity and digital modernization.
Our solutions—backed by a robust network of engineers, cleared employees and technical subject matter experts—continue to be critical to our customers’ priorities. These priorities include addressing global environmental challenges and supporting energy transition, creating digital decision advantages, advancing research and development initiatives, and enhancing space superiority. Examples of our solutions addressing these priorities include development of new advanced energy technologies for the DOE and international customers, threat recognition and analytics for the Intelligence Community, engineering advanced systems for the DOD, research and development solutions for the DHS, and science, engineering, and technology development for NASA. Across our customer set, our solutions span all aspects of the government acquisition lifecycle, including development, engineering, integration, and operations.
As a result of the completion of the spin-off of the Jacobs Critical Mission Solutions business and portions of the Jacobs Divergent Solutions business and merger with the legacy Amentum business in a Reverse Morris Trust transaction (including the related refinancing, the “RMT Transaction”), we have a compelling industry platform of scale with excellent revenue visibility supported by $45.0 billion of backlog as of September 27, 2024 and attractive
S-1


growth opportunities. Our scale is an asset that positions us as a turn-key solutions provider capable of pursuing our customers’ largest and most complex contracts. The ability to pursue these contracts, while maintaining a large base of revenue in backlog, supports our agile business development engine. We believe our scale, efficiency and diversity enables Amentum to generate substantial free cash flow while driving growth.
Business Strategy
We are active in market sectors that are large and fragmented, providing significant opportunities for continued business growth. We leverage our history of executing complex engineering and technology solutions for our largest customers to win new contracts with a business strategy that includes the following elements:
Win and successfully execute the largest, most complex programs for the government across the energy and environmental, intelligence, space, defense, civilian and commercial end-markets. The scale and diversity of our solutions, capabilities, geographies, workforce and contract vehicles are central to our strategy and position us for outsized growth with our customers. The contracts we hold allow us to strategically partner with our customers on innovative engineering and technology solutions creating a competitive advantage for us and provides the opportunity for on-contract growth. We believe the U.S. federal government is increasingly looking to large, diversified providers for comprehensive solutions, for which Amentum offers a breadth and depth of proven expertise that is unique in the government services industry.
Increase our penetration with existing, well-funded customers, where our current long-term contracts, backlog, and relationships provide a stable base for on-contract growth and expanded new opportunities. For example, Amentum has the opportunity to leverage a diverse set of digital modernization and cyber capabilities with longstanding government relationships to grow more broadly in the federal information technology market. We have successfully implemented this strategy with takeaway wins against longtime incumbents on Missile Defense Agency, the United States Space Force, and NASA programs. Our scale and capability set also provides broad access to major government Indefinite Delivery/Indefinite Quantity contract vehicles providing us with access to opportunities for on-contract growth.
Expand into high-growth and adjacent markets by leveraging technologies and innovation backed by our highly skilled workforce, mission expertise, and ecosystem of trusted partners. Some of these high growth areas include hypersonics, autonomous systems, sustainable energy, and artificial intelligence/machine learning. We believe our extensive RDT&E capabilities and our customers’ increasing focus on efficiency will enable us to compete effectively. Our ability to replicate modernization efforts across new end markets and various stages of the government acquisition lifecycle will expand our addressable market and enable growth in excess of our customers’ underlying budgets.
Utilize core competencies to drive revenue synergies generated from our enhanced capabilities, relationships, and past performance credentials. These core competencies position us to bid and win opportunities, and our increased scale and competitive cost structure drive operational efficiencies, without compromising the quality of our solutions. Examples of areas where we combine past performance qualifications with longstanding customer relationships include intelligence analytics, C5ISR engineering & integration, and digital modernization. Our comprehensive offerings support the U.S. and its allies in maintaining a competitive advantage, utilizing innovative solutions to remain well ahead of the technology curve.
Apply our business development engine to continue winning the largest and most complex programs. We complement our strong base of contracts with a proven business development engine that allows us to successfully bid and win new awards. We tailor each proposal to the needs of our customers, including providing the customer on-contract access to additional solutions as needed. We invest in and maintain a high level of collaboration between our operations and business development teams, which helps us retain our long-term contracts and ensure that we are integrating technological advances into our business development process.

Strategic capital allocation through our asset-light business model and disciplined capital allocation policy will prioritize reducing debt in the near-term and delivering long-term value to stakeholders. We regularly evaluate our capital structure and the composition of our business and may from time to time make investments or dispose of certain assets or businesses that we determine are no longer aligned with our strategic growth plans. As previously disclosed by the Company, a near-term priority of the Company following the closing of the RMT Transaction is deleveraging, and we expect any cash proceeds from dispositions in the near-term would be applied in whole or in part to reduce our outstanding indebtedness.
The RMT Transaction
On September 27, 2024, Amentum became a public company through the consummation of the spin-off of the Jacobs Critical Mission Solutions business and portions of the Jacobs Divergent Solutions business (together referred to as the “CMS Business”) and merger with the legacy Amentum business in the RMT Transaction. Prior to the spin-off, the CMS Business reorganized under a newly formed company named Amazon Holdco Inc. (“SpinCo”) and distributed a $911 million cash dividend payment to Jacobs, who then distributed, prior to the merger, approximately 80.95% of the outstanding shares of SpinCo common stock to Jacobs’ shareholders on a pro rata basis. In connection with the completion of the RMT Transaction, SpinCo was renamed Amentum Holdings, Inc. On September 30, 2024, Amentum began trading on the New York Stock Exchange under the ticker symbol “AMTM.”
The Underwriting and Debt-for-Equity Exchange
In connection with the sale of shares of our common stock pursuant to this prospectus supplement, JEG will exchange 19,464,174 shares of our common stock for certain indebtedness of JEG held by the Lender pursuant to an exchange agreement expected to be entered into following the date of this prospectus supplement. The affiliate of the debt-for-equity exchange party, as the selling shareholder in this offering, will then offer those shares of our common stock acquired pursuant to such debt-for-equity exchange in this offering for cash pursuant to this prospectus supplement and the accompanying prospectus. If consummated, the debt-for-equity exchange will occur on the settlement date of this offering, immediately prior to, and its consummation is a condition to, the settlement of the selling shareholder’s sale of the shares to the underwriters. As a result, the consummation of the debt-for-equity exchange is also a condition to the settlement of the underwriters’ sale of the shares to prospective investors. As a result of causing JEG to exchange the shares of our common stock with the Lender, as an affiliate of the selling shareholder, prior to the settlement of this offering, Jacobs may also be deemed to be a selling shareholder in this offering solely for U.S. federal securities law purposes. See “Selling Shareholder” and “Underwriting (Conflicts of Interest).”
The indebtedness of JEG exchanged by the debt-for-equity exchange party will consist of certain term loans borrowed by JEG. The amount of indebtedness of JEG held by the debt-for-equity exchange party is expected to be sufficient to acquire all of the shares of our common stock to be sold by the selling shareholder in this offering. Upon completion of the debt-for-equity exchange, the indebtedness of JEG exchanged in such debt-for-equity exchange will be retired. We do not guarantee or have any other obligations in respect of such indebtedness.
Upon (and assuming) completion of the debt-for-equity exchange, it is expected that Jacobs will beneficially own no shares of our common stock (excluding any additional shares of our common stock that Jacobs may receive pursuant to any post-closing adjustment to the merger consideration after the date hereof).

SUMMARY HISTORICAL FINANCIAL DATA OF AMENTUM
The summary historical consolidated statement of operations data of Amentum for the three months ended December 27, 2024 and December 29, 2023 and the fiscal years ended September 27, 2024, September 29, 2023 and September 30, 2022, the summary historical consolidated statement of cash flows for the three months ended December 27, 2024 and December 29, 2023 and the fiscal years ended September 27, 2024, September 29, 2023 and September 30, 2022 and the summary historical consolidated balance sheet data as of December 27, 2024, September 27, 2024 and September 29, 2023 set forth below have been derived from the audited consolidated financial statements and the unaudited condensed consolidated financial statements of Amentum that are incorporated by reference into this prospectus supplement. Amentum believes these condensed combined financial statements include all normal recurring adjustments necessary to fairly present the results of the interim periods. Amentum Parent Holdings LLC is the accounting acquirer of the CMS Business for accounting purposes in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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 prospectus supplement and in our 2024 Form 10-K and our First Quarter 2025 10-Q, which are incorporated by reference into this prospectus supplement, 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 the CMS Business and current and future results will not be comparable to historical results. In addition, the summary historical consolidated financial data of Amentum for periods prior to the closing of the RMT Transaction does not necessarily reflect what the results of operations and financial position of Amentum would have been if the RMT Transaction had been completed as of the periods presented and the combined business had been operated as a publicly traded company during such periods. In addition, the summary historical consolidated financial data of Amentum does not reflect changes that we expect Amentum to experience in the future as a result of the RMT Transaction, including changes in the financing, operations, cost structure and personnel needs of Amentum. Accordingly, these historical results should not be relied upon as indicators of future performance. The summary historical consolidated financial data of Amentum should be read in conjunction with the section of each of our 2024 Form 10-K and First Quarter 2025 Form 10-Q entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the section entitled “Certain Relationships and Related Person Transactions” incorporated by reference from our 2025 proxy statement into our 2024 Form 10-K, as well as our audited condensed consolidated financial statements and the corresponding notes thereto, our unaudited condensed consolidated financial statements and corresponding notes thereto and the audited combined financial statements and unaudited condensed combined financial statements of the Critical Missions Solutions and Cyber & Intelligence Businesses of Jacobs and related notes thereto, in each case incorporated by reference in this prospectus supplement.

SUMMARY UNAUDITED PRO FORMA FINANCIAL INFORMATION
The following table presents certain summary unaudited pro forma financial information, which has been derived from our unaudited pro forma condensed combined statement of operations and notes thereto for the year ended September 27, 2024, incorporated by reference herein from our Current Report on Form 8-K filed with the SEC on March 7, 2025. The summary unaudited pro forma financial information gives effect to the RMT Transaction as if it occurred as of September 30, 2023.
The summary unaudited pro forma financial information has been prepared reflecting the acquisition method of accounting. Amentum Parent Holdings LLC is the accounting acquirer of the CMS Business for accounting purposes in accordance with GAAP. Under the acquisition method of accounting, the assets of SpinCo that were acquired and liabilities of SpinCo that were assumed were recorded at fair value at the acquisition date. As of the date of the unaudited pro forma condensed combined statement of operations for the year ended September 27, 2024, Amentum has used currently available information to determine the preliminary fair value estimates of such assets acquired and liabilities assumed. As a result of the foregoing and the continued analysis that Amentum will complete through the end of the 12-month measurement period in connection with the application of ASC 805 (the “Measurement Period”), the transaction accounting adjustments are preliminary and subject to change as additional information becomes available and additional analysis is performed.
The summary unaudited pro forma financial information is for informational purposes only and does not purport to represent what Amentum’s financial position and results of operations actually would have been had the RMT Transaction occurred on the dates indicated, or to project Amentum’s financial performance for any future period. The pro forma adjustments contained in the unaudited pro forma condensed combined statement of operations incorporated by reference herein are based on the information currently available, and the assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes to the unaudited pro forma condensed combined statement of operations. Actual results are subject to change based on any adjustments made during the Measurement Period, which is expected to be completed no later than 12 months following the closing of the RMT Transaction.
The summary unaudited pro forma financial information does not give effect to the potential impact of current financial conditions, or any anticipated costs of operating as a standalone company, dis-synergies, revenue enhancements, cost savings or operational efficiencies that may result from the RMT Transaction. No assurances of the timing or the amount of any cost synergies able to be captured, or the costs necessary to achieve those cost synergies, can be provided.
The unaudited pro forma financial information shown below should be read in conjunction with our unaudited pro forma condensed combined statement of operations of Amentum and notes thereto for the year ended September 27, 2024, incorporated by reference herein, as well as the section of each of our 2024 Form 10-K and the First Quarter 2025 Form 10-Q entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the section entitled “Certain Relationships and Related Person Transactions” incorporated by reference from our 2025 proxy statement into our 2024 Form 10-K, as well as our audited condensed consolidated financial statements and the corresponding notes thereto, our unaudited condensed consolidated financial statements and corresponding notes thereto and the audited combined financial statements and unaudited condensed combined financial statements of the Critical Missions Solutions and Cyber & Intelligence Businesses of Jacobs and related notes thereto, in each case incorporated by reference into this prospectus supplement. For factors that could cause actual results to differ materially from those presented in the unaudited pro forma condensed combined financial information, see “Information Relating to Forward-Looking Statements” herein and “Risk Factors” in the accompanying prospectus and in our 2024 Form 10-K and First Quarter 2025 Form 10-Q.

USE OF PROCEEDS
All shares of our common stock sold pursuant to this prospectus will be offered and sold by the selling shareholder. We will not receive any proceeds from such sale.
BofA Securities, Inc. will receive all of the net proceeds of this offering. As such, BofA Securities, Inc. (in its capacity as underwriter) is deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. Accordingly, this offering will be conducted in compliance with the requirements of Rule 5121. The appointment of a “qualified independent underwriter” is not required in connection with this offering as a “bona fide public market,” as defined in Rule 5121, exists for our common stock.

S-12


SELLING SHAREHOLDER
The following table provides information with respect to the beneficial ownership of our common stock, as of February 27, 2025, by Jacobs, which might be deemed to be a selling shareholder in this offering, solely for U.S. federal securities law purposes, as a result of the debt-for-equity exchange (if consummated) with the Lender, as an affiliate of the selling shareholder. As of February 27, 2025, 243,303,999 shares of our common stock are issued and outstanding, including 9,732,087 shares of our common stock in escrow pending release in connection with post-closing adjustments to the merger consideration, but excluding (i) 18,341,084 shares of common stock reserved for issuance under our 2024 Stock Incentive Plan and (ii) 2,644,588 shares of common stock available for purchase under our Employee Stock Purchase Plan. The percentage set forth in the table below is based on this share count.
The selling shareholder, BofA Securities, Inc., is offering all of the shares of common stock being sold in this offering. All of the shares of our common stock being registered under this prospectus supplement and the accompanying prospectus are currently beneficially owned by Jacobs. Jacobs has, to our knowledge, sole investment power with respect to 19,464,174 shares of our common stock as of the date of this prospectus supplement (including 1,216,511 shares of our common stock released from escrow to Jacobs pursuant to a post-closing adjustment to the merger consideration, but excluding the remaining 9,732,087 additional merger consideration shares, which remain held in escrow as of the date of this prospectus supplement). Pursuant to the Registration Rights Agreement, Jacobs granted us, and caused each other direct or indirect subsidiary of Jacobs (including JEG) to the extent such subsidiary holds shares of our common stock retained in connection with the RMT Transaction to grant us, a proxy to vote the shares of our common stock owned by Jacobs and its subsidiaries in proportion to the votes cast by our other shareholders. As a result, Jacobs and its subsidiaries do not exercise voting power over any of the shares of our common stock that they beneficially own.
In connection with the sale of shares of our common stock pursuant to this prospectus supplement, JEG will exchange 19,464,174 shares of our common stock for certain indebtedness of JEG held by the Lender pursuant to a debt-for equity exchange agreement expected to be entered into following the date of this prospectus supplement. The affiliate of the debt-for-equity exchange party, as the selling shareholder in this offering, will then offer those shares of our common stock acquired pursuant to such debt-for-equity exchange in this offering for cash pursuant to this prospectus supplement and the accompanying prospectus. If consummated, the debt-for-equity exchange will occur on the settlement date of this offering, immediately prior to, and its consummation is a condition to, the settlement of the selling shareholder’s sale of the shares to the underwriters. As a result, the consummation of the debt-for-equity exchange is also a condition to the settlement of the underwriters’ sale of the shares to prospective investors. As a result of causing JEG to exchange the shares of our common stock with the Lender, as an affiliate of the selling shareholder, prior to the settlement of this offering, Jacobs may also be deemed to be a selling shareholder in this offering solely for U.S. federal securities law purposes.
The information concerning the beneficial ownership of shares of common stock by Jacobs, as of February 27, 2025 included in this prospectus supplement has been obtained from Jacobs and excludes additional shares of our common stock that may be received pursuant to any post-closing adjustment to the merger consideration.
After giving effect to the expected debt-for-equity exchange, BofA Securities, Inc., as the Lender’s designee for the receipt of shares it will receive in the debt-for-equity exchange, would hold approximately 8.0% of our common stock, all of which shares would have been acquired from JEG in the debt-for-equity exchange and all of which shares are offered to be sold by the selling shareholder in this offering. See “Underwriting (Conflicts of Interest).”

BofA Securities, Inc. is acting as representative of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us, JEG, the selling shareholder and the underwriters, the selling shareholder has agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from the selling shareholder, the number of shares of common stock set forth opposite its name below.

19,464,174
Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares of common stock are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.
We, JEG and the selling shareholder have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.
The underwriters are offering the shares of common stock, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
Discounts
The representative has advised us and the selling shareholder that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $        per share. After the offering, the public offering price, concession or any other term of the offering may be changed.
The following table shows the public offering price, underwriting discount and proceeds before expenses to the selling shareholder.

The expenses of the Company and Jacobs for the offering, not including the underwriting discount, are estimated at approximately $2.15 million and are payable by us.
No Sales of Similar Securities
We, Jacobs, our executive officers and directors have agreed not to sell or transfer any common stock or securities convertible into, exchangeable for, exercisable for, or repayable with common stock, for 90 days after the
S-15


date of this prospectus supplement without first obtaining the written consent of BofA Securities, Inc. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:
offer, pledge, sell or contract to sell any common stock,
sell any option or contract to purchase any common stock,
purchase any option or contract to sell any common stock,
grant any option, right or warrant for the sale of any common stock,
lend or otherwise transfer or dispose of any common stock,
exercise any right with respect to the registration of any common stock, request or demand that we file or make a confidential submission of a registration statement related to the common stock, or
enter into any hedging, swap, loan or other or other agreement or transaction (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward or any other derivative transaction or instrument, however described or defined) that transfers, in whole or in part, the economic consequence of ownership of any common stock whether any such hedging, swap, loan or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.
This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition. Notwithstanding the foregoing, Jacobs and JEG may freely transfer common stock without the prior written consent of the representative in connection with any pro rata distribution of common stock by JEG or Jacobs to shareholders of Jacobs.
New York Stock Exchange Listing
The shares are listed on the New York Stock Exchange under the symbol “AMTM.”
Price Stabilization, Short Positions
Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representative may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.
In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.
Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.
Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
S-16


Electronic Distribution
In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail.
Conflicts of Interest
BofA Securities, Inc., as selling shareholder in this offering, will receive all of the net proceeds of this offering. As such, BofA Securities, Inc. (in its capacity as underwriter) is deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. Accordingly, this offering will be conducted in compliance with the requirements of Rule 5121. The appointment of a “qualified independent underwriter” is not required in connection with this offering as a “bona fide public market,” as defined in Rule 5121, exists for our common stock. In accordance with Rule 5121, BofA Securities, Inc. will not confirm any sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder. See “Use of Proceeds.”
Other Relationships
Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. For example, certain of the underwriters and/or their respective affiliates are lenders under our credit agreement and Jacobs’ credit agreement.
In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours, Jacobs or respective affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.
The Debt-for-Equity Exchange
JEG and the Lender expect to enter into an exchange agreement prior to the settlement of this offering. Under the exchange agreement, JEG expects to exchange the shares of common stock to be sold in this offering for certain indebtedness of JEG held by the Lender. The selling shareholder will then sell those shares to the underwriters for cash. Upon (and assuming) completion of the debt-for-equity exchange, the JEG indebtedness exchanged in such debt-for-equity exchange will be retired. If consummated, the debt-for-equity exchange would occur on the settlement date of this offering, immediately prior to the settlement of the selling shareholder’s sale of the shares to the underwriters. The consummation of the debt-for-equity exchange is a condition to the settlement of the selling shareholder’s sale of the shares to the underwriters. As a result, the consummation of the debt-for-equity exchange is also a condition to the settlement of the underwriters’ sale of the shares to prospective investors.
The indebtedness of JEG expected to be exchanged by the debt-for-equity exchange party would consist of indebtedness outstanding under an existing term loan agreement. It is expected that this amount of indebtedness will be sufficient to acquire all of the shares of our common stock to be sold by the selling stockholder in this offering. We do not guarantee or have any other obligations in respect of such indebtedness.
The pricing with respect to the debt-for-equity exchange will (i) be negotiated at arm’s length, (ii) involve a fixed amount and (iii) not contain any variable component. The selling shareholder will acquire and sell the shares of common stock as principal for its own account, rather than on JEG’s behalf. Under the exchange agreement described above, the selling shareholder, as the Lender’s designee, will become the owner of our shares of common stock delivered to it pursuant to the debt-for-equity exchange on the settlement date of this offering and the JEG indebtedness exchanged in such debt-for-equity exchange will be retired. The selling shareholder will receive all the net proceeds from the sale of the shares in this offering. Neither we nor JEG will receive any proceeds from the offering.
S-17


Under U.S. federal securities laws, the selling shareholder will be deemed to be an underwriter with respect to any shares of common stock that it acquires pursuant to the debt-for-equity exchange, if consummated, and sells in this offering; however, references to the underwriters in this prospectus supplement refer only to the underwriters listed in the first paragraph of this “Underwriting (Conflicts of Interest)” section and acting in their capacity as underwriters. Jacobs may be deemed to be a selling shareholder solely for U.S. federal securities law purposes with respect to any shares of common stock that the Lender acquires from JEG pursuant to the debt-for-equity exchange and such shares are sold in this offering.

Common Stock
This prospectus relates to the offer and sale of up to 19,464,174 shares of our common stock, par value $0.01 per share (the “common stock”). All of these shares of our common stock are currently held by Jacobs Engineering Group, Inc. (“JEG”), a wholly-owned subsidiary of Jacobs Solutions Inc. (“Jacobs”). We are registering such shares under the terms of the Registration Rights Agreement by and between us and Jacobs, dated September 27, 2024 (the “Registration Rights Agreement”). We will not receive any of the proceeds from the sale of shares of our common stock under this prospectus.
Jacobs or one or more of its subsidiaries will exchange shares of our common stock for certain indebtedness of JEG or certain of its subsidiaries held by a debt-for-equity exchange party (as defined herein), which debt-for-equity exchange party may offer for sale shares of our common stock acquired pursuant to such debt-for-equity exchange pursuant to this prospectus and the applicable prospectus supplement. Any offers and sales pursuant to this prospectus will involve such a debt-for-equity exchange, and any reference herein to the selling shareholder refers to the applicable debt-for-equity exchange party or parties. We will amend or supplement this prospectus to name such debt-for-equity exchange party or parties as a selling shareholder prior to any such offers and sales. Jacobs may also be deemed a selling shareholder in any such offering solely for U.S. federal securities laws purposes. See “Selling Shareholder” and “Plan of Distribution (Conflicts of Interests).”
If the shares of our common stock are sold by the selling shareholder through underwriters or broker-dealers, the selling shareholder (and not us) will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of our common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices.
At the time the selling shareholder offers shares registered by this prospectus, we will amend or supplement this prospectus to include specific information about the terms of the offering to potentially add to or update the information in this prospectus. You should read this prospectus and any applicable prospectus supplement carefully before you invest.
The selling shareholder may offer the shares in amounts, at prices and on terms determined by market conditions at the time of the offering. The selling shareholder may sell shares through agents it selects or through underwriters and dealers it selects. The selling shareholder also may sell shares directly to investors. If the selling shareholder uses agents, underwriters or dealers to sell the shares, we will name them and describe their compensation in an amendment or supplement to this prospectus.
Our common stock is listed on the New York Stock Exchange (the “NYSE”) under the symbol “AMTM”. On March 7, 2025, the closing price of our common stock as reported on the NYSE was $19.99 per share.

INFORMATION RELATING TO FORWARD-LOOKING STATEMENTS
Certain information included or incorporated by reference in this prospectus, any accompanying prospectus supplement, and other written or oral statements that we make from time to time may not address historical facts and, therefore, could be interpreted to be “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995 and other federal securities laws.

Forward-looking statements may be characterized by terminology such as “believe,” “anticipate,” “expect,” “should,” “intend,” “plan,” “will,” “estimates,” “projects,” “strategy” and similar expressions. These statements are based on assumptions and assessments made by Amentum’s management in light of its experience and its perception of historical trends, current conditions, expected future developments and other factors it believes to be appropriate. These forward-looking statements are subject to a number of risks and uncertainties that include but are not limited to the factors set forth under the sections entitled “Risk Factors” in this prospectus and any accompanying prospectus supplement and “Item 1A. Risk Factors” of our 2024 Form 10-K and our First Quarter 2025 Form 10-Q.
Any such forward-looking statements are not guarantees of future performance, and actual results, developments and business decisions may differ materially from those envisaged by such forward-looking statements.

PROSPECTUS SUMMARY
This summary contains basic information about us and this offering. Because it is a summary, it does not contain all of the information that you should consider before investing. Before you decide to invest in our common stock, you should carefully read the entire prospectus and the documents incorporated by reference herein, including the sections entitled “Risk Factors” and “Information Relating to Forward-Looking Statements” in this prospectus, any free writing prospectus prepared by or on behalf of us that we have referred to you, the sections entitled “Item 1A.

Company Overview
Amentum 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.
Our history as a trusted partner to the U.S. federal government and our advanced engineering and technology expertise enable us to lead and support our customers’ most complex programs. Our broad capabilities support technology-driven, full mission lifecycle solutions that align with modernization priorities for a wide array of customers. We believe our scale and breadth of capabilities position us well in the marketplace as our customers’ requirements increasingly necessitate a full lifecycle partner equipped with next-generation engineering solutions to solve their most complex challenges.
Our workforce of more than 53,000 continues to be rooted in a strong purpose-driven culture. Our mission-oriented and highly skilled personnel enable us to serve a diverse range of requirements for our customers. In the U.S., these customers include the Department of Energy (“DOE”), the Intelligence Community (consisting of the National Intelligence Program and the Military Intelligence Program), the Department of Defense (“DOD”), the National Aeronautics and Space Administration (“NASA”), and the Department of Homeland Security (“DHS”) as well as other government and certain commercial customers. We are also well-positioned internationally with employees across approximately 80 countries, supporting international customers and contracts in regions with growing mission demand, such as Europe and the Indo-Pacific, and with key allied government agencies, including the U.K. Ministry of Defence, the U.K. Nuclear Decommissioning Authority and the Australian Department of Defence. We support these customers by providing solutions to pressing challenges, from energy transition and environmental solutions to cybersecurity and digital modernization.
Our solutions—backed by a robust network of engineers, cleared employees and technical subject matter experts—continue to be critical to our customers’ priorities. These priorities include addressing global environmental challenges and supporting energy transition, creating digital decision advantages, advancing research and development initiatives, and enhancing space superiority. Examples of our solutions addressing these priorities include development of new advanced energy technologies for the DOE and international customers, threat recognition and analytics for the Intelligence Community, engineering advanced systems for the DOD, research and development solutions for the DHS, and science, engineering, and technology development for NASA. Across our customer set, our solutions span all aspects of the government acquisition lifecycle, including development, engineering, integration, and operations.
As a result of the completion of the spin-off of the Jacobs Critical Mission Solutions business and portions of the Jacobs Divergent Solutions business and merger with the legacy Amentum business in a Reverse Morris Trust transaction (including the related refinancing, the “RMT Transaction”), we have a compelling industry platform of scale with excellent revenue visibility supported by $45.0 billion of backlog as of September 27, 2024 and attractive growth opportunities. Our scale is an asset that positions us as a turn-key solutions provider capable of pursuing our
1


customers’ largest and most complex contracts. The ability to pursue these contracts, while maintaining a large base of revenue in backlog, supports our agile business development engine. We believe our scale, efficiency and diversity enables Amentum to generate substantial free cash flow while driving growth.
The RMT Transaction
On September 27, 2024, Amentum became a public company through the consummation of the spin-off of the Jacobs Critical Mission Solutions business and portions of the Jacobs Divergent Solutions business (together referred to as the “CMS Business”) and merger with the legacy Amentum business in the RMT Transaction. Prior to the spin-off, the CMS Business reorganized under a newly formed company named Amazon Holdco Inc. (“SpinCo”) and distributed a $911 million cash dividend payment to Jacobs, who then distributed, prior to the merger, approximately 80.95% of the outstanding shares of SpinCo common stock to Jacobs’ shareholders on a pro rata basis. In connection with the completion of the RMT Transaction, SpinCo was renamed Amentum Holdings, Inc.

THE OFFERING
Common Stock Offered by the Selling Shareholder
Up to 19,464,174 shares of our common stock.
Use of Proceeds
All shares of our common stock sold pursuant to this prospectus will be offered and sold by the selling shareholder. We will not receive any proceeds from such sale. See “Use of Proceeds.”
Selling Shareholder
In connection with sales of shares of our common stock pursuant to the registration statement of which this prospectus forms a part, Jacobs or one or more of its subsidiaries will exchange up to 19,464,174 shares of our common stock for certain indebtedness of JEG or certain of its subsidiaries held by one or more of the underwriters or broker-dealers (or affiliates thereof), which we refer to, in such role, as a “debt-for-equity exchange party.” Any offers and sales pursuant to this prospectus will involve such a debt-for-equity exchange party, and any reference to the “selling shareholder” refers to the applicable debt-for-equity exchange party or parties. We will amend or supplement this prospectus to name such debt-for-equity exchange party or parties as a selling shareholder prior to any such offers and sales. Jacobs may also be deemed a selling shareholder in such an offering solely for U.S. federal securities laws purposes.
See “Selling Shareholder.”
Plan of Distribution (Conflicts of Interest)
The selling shareholder may offer the shares in amounts, at prices and on terms determined by market conditions at the time of the offering. The selling shareholder may sell shares through agents it selects or through underwriters and dealers it selects. The selling shareholder also may sell shares directly to investors. If the selling shareholder uses agents, underwriters or dealers to sell the shares, we will name them and describe their compensation in an amendment or supplement to this prospectus.
See “Plan of Distribution (Conflicts of Interest).”
Conflicts of Interest
One or more debt-for-equity exchange parties (or one or more of their respective affiliates) would be the selling shareholder and either such debt-for-equity exchange parties or one or more of their respective affiliates would also act as an underwriter in such offering. Because the selling shareholder in any such offering would be an underwriter or an affiliate of an underwriter, if such selling shareholder receives 5% or more of the net proceeds of such offering, such selling shareholder (in its capacity as an underwriter) or such affiliate of such selling shareholder acting as an underwriter would be deemed to have a “conflict of interest” under FINRA Rule 5121. Accordingly, any such offering would be conducted in compliance with the requirements of Rule 5121. The appointment of a “qualified independent underwriter” would not be required in connection with any such offering because a “bona fide public market,” as defined in Rule 5121, exists for our common stock. In accordance with FINRA Rule 5121, any such underwriter with a conflict of interest would not confirm any sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder. See “Plan of Distribution (Conflicts of Interest).”

RISK FACTORS
You should carefully consider the following risks and the risks described in “Item 1A. Risk Factors” in our 2024 Form 10-K and First Quarter 2025 Form 10-Q filed with the SEC and incorporated by reference into this prospectus, and other information in this prospectus, including the financial statements incorporated by reference herein, any applicable prospectus supplement and any applicable free writing prospectus prepared by or on behalf of us that we have referred to you, in evaluating Amentum and our common stock. The following risk factors present material risks and uncertainties associated with this offering. The risks described below, in our 2024 Form 10-K and in our First Quarter 2025 Form 10-Q are material risks, although not the only risks, that we face. The occurrence of one or more of the events or circumstances described in these risk factors and in “Item 1A. Risk Factors” in our 2024 Form 10-K and our First Quarter 2025 Form 10-Q, alone or in combination with other events or circumstances, may have an adverse effect on our business, financial condition or results of operations. We may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial, which may also impair our business, financial condition or results of operations.
Risks Related to the Offering
The trading market for our common stock has existed for only a short period following the RMT Transaction. The price and trading volume of our common stock has been and may continue to be volatile, and the value of an investment in our common stock could decline.
Prior to the RMT Transaction, there was no public market for our common stock. An active trading market for our common stock commenced only recently following the completion of the RMT Transaction and may not be sustainable. If you invest in our common stock, you may not be able to resell your shares of common stock at or above the price at which your shares were acquired. We cannot predict the prices at which our common stock may trade. The market price and trading volume of our common stock has and may continue to fluctuate widely, depending on many factors, some of which may be beyond our control, including:
actual or anticipated fluctuations in our operating results due to factors related to our business;
success or failure of our business strategies;
our quarterly or annual earnings, or those of other companies in our industry;
our ability to obtain financing as needed;
announcements by us or our competitors of significant acquisitions or dispositions;
changes in accounting standards, policies, guidance, interpretations or principles;
the failure of securities analysts to cover our common stock after the RMT Transaction;
changes in earnings estimates by securities analysts or our ability to meet those estimates;
the operating and stock price performance of other comparable companies;
investor perception of our company and our industry;
overall market fluctuations;
results from any material litigation or government investigation;
changes in laws and regulations (including tax laws and regulations) affecting our business;
changes in capital gains taxes and taxes on dividends affecting shareholders; and
general economic conditions and other external factors.

Furthermore, our business profile and market capitalization may not fit the investment objectives of some Jacobs’ shareholders and, as a result, these Jacobs’ shareholders may sell their shares of our common stock. Low trading volume for our stock, which may occur if an active trading market does not develop, among other reasons, would amplify the effect of the above factors on our stock price volatility.
Stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations could adversely affect the trading price of our common stock.
A significant number of shares of our common stock may be sold or otherwise disposed of, including the shares of our common stock that Jacobs initially owns (whether pursuant to this registration statement or otherwise), which may cause our stock price to decline.
Any sales of substantial amounts of our common stock in the public market, or the perception that such sales might occur, may cause the market price of our common stock to decline. As of February 27, 2025, we have an aggregate of 243,303,999 shares of common stock issued and outstanding. Shares distributed to Jacobs’ shareholders in the RMT Transaction generally are freely tradeable without restriction or further registration under the Securities Act, except for shares owned by our “affiliates,” as that term is defined in Rule 405 under the Securities Act, which shares may be freely sold in the public market as unrestricted shares if registered under the Securities Act or if they qualify for an exemption from registration under Rule 144 under the Securities Act. Sponsor Stockholder (as defined below) also holds a substantial portion of the issued and outstanding shares of our common stock.
We cannot predict whether large amounts of our common stock will be sold in the open market. We are also unable to predict whether a sufficient number of buyers of our common stock to meet the demand to sell shares of our common stock at attractive prices would exist at that time.
In addition, Jacobs has determined that it does not intend to retain more than 8% of the issued and outstanding shares of our common stock after the RMT Transaction and any post-closing adjustments to the merger consideration. Jacobs has informed us that any additional shares to which Jacobs would otherwise be entitled in excess of 8% of the issued and outstanding shares of our common stock after the RMT Transaction will be distributed, on a pro rata basis, to Jacobs’ shareholders. As the amount of merger consideration was not finally determined by the effective time of the merger, 10,948,598 shares of our common stock, representing approximately 4.5% of the issued and outstanding shares of our common stock, were placed in escrow pending the determination of whether Amentum Equityholder (as defined below) is entitled to such consideration (the “escrow holding”), such additional merger consideration (if any) to be delivered through the escrow holding. On February 17, 2024, 1,216,511 shares of such additional merger consideration representing approximately 0.5% of the issued and outstanding shares of our common stock was delivered from the escrow holding to Jacobs (which shares are included in the up to 19,464,174 shares offered pursuant to this prospectus). Jacobs has disclosed that it intends to dispose of all the shares of our common stock that it retains after the RMT Transaction, which dispositions may include one or more exchanges for Jacobs debt or distributions to Jacobs’ shareholders relating to the 19,464,164 shares held by Jacobs as of the date of this prospectus.
We have agreed that, upon the request of Jacobs or Sponsor Stockholder and pursuant to the terms of the Registration Rights Agreement or the Stockholders Agreement by and between Amentum and Amentum Joint Venture LP (“Amentum Equityholder”), dated September 27, 2024 (the “Stockholders Agreement”), respectively, we will use our reasonable best efforts to effect a registration under applicable federal and state securities laws of any shares of our common stock held by Jacobs or Sponsor Stockholder, as applicable. See “Certain Relationships and Related Person Transactions — Jacobs Agreements —Registration Rights Agreement” and “Certain Relationships and Related Person Transactions — Related Person Transactions —Stockholders Agreement” incorporated by reference herein from our proxy statement filed on January 21, 2025. We are filing the registration statement on Form S-1 of which this prospectus forms a part pursuant to a request from Jacobs to register under the Securities Act all 19,464,174 of the shares of our common stock beneficially owned by Jacobs as of the date of this prospectus. Jacobs has informed us that any additional shares to which Jacobs would otherwise be entitled (not including the approximately 0.5% of the issued and outstanding shares of our common stock already received by Jacobs) will be distributed, on a pro rata basis, to Jacobs’ shareholders. The remaining shares of common stock in
6


the escrow holding could be released to Jacobs and could be distributed by Jacobs to its shareholders at any time, including in close proximity to any offering of shares of common stock pursuant to this prospectus. Any dispositions of substantial amounts of shares of our common stock in the public market, including any disposition of the shares beneficially owned by Jacobs or Sponsor Stockholder (whether pursuant to this registration statement or otherwise), or the perception that such dispositions might occur, may cause the market price of our common stock to decline.
Your percentage of ownership in Amentum may be diluted in the future.
Your percentage ownership may be diluted in the future by the equity awards that we expect to grant to our directors, officers and other employees. We have approved an incentive plan that provides for the grant of common stock-based equity awards to our directors, officers and other employees. We have also approved a stock purchase plan that generally provides for purchases by certain eligible employees of shares of our common stock upon completion of an offering through contributions of a whole percentage of their eligible compensation. On each of October 4, 2024 and November 8, 2024, we filed a registration statement on Form S-8 registering under the Securities Act (i) an aggregate of approximately 18,000,000 shares of common stock underlying equity awards we have made and will make to our employees and certain other qualifying individuals, and the resale of those shares of common stock and (ii) an aggregate of approximately 2,600,000 shares of common stock underlying our employee stock purchase plan, and the resale of those shares of common stock. In addition, we may issue equity as all or part of the consideration paid for acquisitions and strategic investments that we may make in the future or as necessary to finance our ongoing operations.
None of the proceeds from the sale of shares of our common stock by the selling shareholder will be available to us to fund our operations.
We will not receive any proceeds from the sale of shares of our common stock by the selling shareholder. The selling shareholder will receive all proceeds from the sale of such shares. Consequently, none of the proceeds from such sale by the selling shareholder will be available to us to fund our operations, capital expenditures, compensation plans or acquisition opportunities. See “Use of Proceeds.”
There can be no assurance that we will pay dividends on our common stock.
We do not expect to declare or pay any cash dividends on our common stock. Any future determination as to the timing, declaration, amount and payment of any dividends will be within the discretion of our Board of Directors, and will depend upon, among other things, our financial condition, earnings, capital requirements of our operating subsidiaries, regulatory constraints, industry practice, ability to access capital markets and other factors deemed relevant by our Board of Directors, including legal and contractual restrictions. Moreover, if we determine to pay any dividends in the future, there can be no assurance that we will continue to pay such dividends or the amount of such dividends.
Our accounting and other management systems and resources may not be adequately prepared to meet the financial reporting and other requirements to which we are subject to as a standalone, publicly traded company. Fulfilling our obligations incident to being a public company and implementing the requirements of and related rules under the Sarbanes-Oxley Act of 2002, is expensive and time-consuming, and any delays or difficulty in satisfying these obligations could have a material adverse effect on our future results of operations and our stock price.
Starting in fiscal year 2025, as a public company, the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the SEC, as well as the NYSE rules, will require us to implement various corporate governance practices and adhere to a variety of reporting requirements and complex accounting rules. Compliance with these public company obligations will require us to devote significant management time and place significant additional demands on our finance, accounting, and legal staff and on our management systems, including our financial, accounting and information systems. Other expenses associated with being a public company include increased auditing, accounting, and legal fees and expenses, investor relations expenses, increased directors’ fees and director and officer liability insurance costs, registrar and transfer agent fees, listing fees, as well as other expenses.
7


In particular, starting in fiscal year 2025, the Sarbanes-Oxley Act of 2002 will require us to document and test the effectiveness of our internal control over financial reporting in accordance with an established internal control framework, and to report on our conclusions as to the effectiveness of our internal controls. It also will require an independent registered public accounting firm to test our internal control over financial reporting and report on the effectiveness of such controls. In addition, we are required under the Exchange Act to maintain disclosure controls and procedures and internal control over financial reporting. Because of inherent limitations in any internal control environment, there can be no assurance that all control issues and instances of fraud, errors or misstatements, if any, within the Company has been or will be detected on a timely basis. Such deficiencies could result in the correction or restatement of financial statements of one or more periods.
Any failure to maintain effective controls or implement new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. We also rely on third parties for certain calculations and other information that support our accounting and financial reporting, which includes reports from such organizations on their controls and systems that are used to generate this data and information. Any failure by such third parties to provide us with accurate or timely information or to implement and maintain effective controls may cause us to fail to meet our reporting obligations as a publicly traded company. In addition, as we operate our financial management systems, we could experience deficiencies in their operation that could have an adverse effect on the effectiveness of our internal control over financial reporting.
In the future, when required, if we are unable to conclude that we have effective internal control over financial reporting, or if our independent registered public accounting firm is unable to provide us with an unqualified report regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our consolidated financial statements, which could result in a decrease in the value of our common stock. Starting in fiscal year 2025, failure to comply with the Sarbanes-Oxley Act of 2002 could potentially subject us to sanctions or investigations by the SEC, the NYSE, or other regulatory authorities.
We have a significant amount of indebtedness, which could adversely affect our financial condition or decrease our business flexibility.
On August 13, 2024, we completed an offering of $1.0 billion in aggregate principal amount of 7.250% senior notes due August 1, 2032. Additionally, on September 27, 2024, we entered into a new first lien credit agreement, including a new senior secured credit facility which provided for a $3,750.0 million term loan facility and a $850.0 million revolving credit facility. Our level of indebtedness could have important consequences, including, but not limited to:
reducing our flexibility to respond to changing business and economic conditions, and increasing our vulnerability to general adverse economic and industry conditions;
requiring us to dedicate a substantial portion of our cash flows from operations to make debt service payments, thereby reducing the availability of cash flows to fund working capital, capital expenditures, dividends, share repurchases, acquisitions and investments and other general corporate purposes;
limiting our flexibility in planning for, or reacting to, challenges and opportunities, and changes in our businesses and the markets in which we operate;
limiting our ability to obtain additional financing to fund our working capital, capital expenditures, dividends, acquisitions and debt service requirements and other financing needs;
increasing our vulnerability to increases in interest rates in general because a substantial portion of our indebtedness bears interest at floating rates; and
placing us at a competitive disadvantage to our competitors that have less debt.
Each financial institution that is part of the syndicate for the revolving facility is responsible on a several, and not joint, basis for providing a portion of the loans to be made under the revolving facility. If any financial institution or group of financial institutions with a significant portion of the commitments in the revolving facility
8


fails to satisfy its or their respective obligations to extend credit under the revolving facility and we are unable to find a replacement for such participant or participants on a timely basis (if at all), our liquidity and results of operations may be adversely affected.
Our ability to service our indebtedness will depend on our future operating performance and financial results, which will be subject, in part, to factors beyond our control, including interest rates and general economic, financial and business conditions. If we do not have sufficient cash flow to service our indebtedness, we may need to refinance all or part of our indebtedness, borrow more money or sell securities or assets, some or all of which may not be available to us at acceptable terms or at all. In addition, we may need to incur additional indebtedness in the future. Although the terms of our indebtedness allow us to incur additional indebtedness, this would be subject to certain limitations which may preclude us from incurring the amount of indebtedness we otherwise desire.
Delaware law and anti-takeover provisions in our amended and restated articles of incorporation, amended and restated bylaws, stockholders agreement and other governance documents may impede or discourage a takeover or change of control and limit the power of our shareholders.
We are a Delaware corporation. Certain anti-takeover provisions of the General Corporation Law of the State of Delaware (the “DGCL”) impose restrictions on the ability of others to acquire control of us. In addition, certain provisions of our governance documents may impede or discourage a takeover. For example:
vacancies occurring on our board can be filled only by our Board of Directors;
increasing or decreasing the size of the Board of Directors will require the affirmative vote of at least 80% of the members of the Board of Directors at such time;
prior to the first anniversary of September 27, 2024 (the “Closing Date”), Amentum Equityholder and certain affiliated transferees upon execution of a joinder agreement to the Stockholders Agreement (together with Amentum Equityholder, “Sponsor Stockholder”) must vote its Amentum common stock in favor of directors on the initial Board of Directors that were proposed by Jacobs and shall not seek, propose or vote its Amentum common stock in favor of the removal of such directors, other than for cause;
prior to the second anniversary of the closing date, Sponsor Stockholder must vote its Amentum common stock in favor of the Executive Chair of the Board of Directors and shall not seek, propose or vote its Amentum common stock in favor of their removal, other than for cause;
shareholders do not have the right to call a special meeting or to act by written consent;
certain of the provisions in our amended and restated certificate of incorporation will require supermajority shareholder approval for amendments;
shareholders will have to follow certain procedures and notice requirements in order to present certain proposals or nominate directors for election at shareholder meetings;
our Stockholders Agreement prohibits, for three years following the closing of the RMT Transaction, amendments to our amended and restated certificate of incorporation and bylaws to provide our shareholders with proxy access rights; and
our Board of Directors has the power to designate and issue, without any further vote or action by our shareholders, shares of preferred stock from time to time in one or more series.
In addition, we are subject to Section 203 of the DGCL, which could have the effect of delaying or preventing a change of control that you may favor. Section 203 provides that, subject to limited exceptions, persons that acquire, or are affiliated with persons that acquire, more than 15% of the outstanding voting stock of a Delaware corporation may not engage in a business combination with that corporation, including by merger, consolidation or acquisitions of additional shares, for a three-year period following the date on which that person or any of its affiliates becomes the holder of more than 15% of the corporation’s outstanding voting stock.
9


These types of provisions, as well as our Stockholders Agreement, could make it more difficult for a third party to acquire control of us, even if the acquisition would be beneficial to our shareholders. Accordingly, shareholders may be limited in the ability to obtain a premium for their shares.
Our amended and restated certificate of incorporation designates certain courts within the State of Delaware as the exclusive forum for certain types of actions and proceedings that may be initiated by our shareholders, and the federal district courts of the United States as the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act, which could limit our shareholders’ ability to choose the judicial forum for disputes with us or our directors, officers or employees.
Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or shareholders to us or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of our amended and restated certificate of incorporation, amended and restated bylaws or the DGCL, or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware and (iv) any other action asserting a claim against us that is governed by the internal affairs doctrine, in each case, may be brought only in specified courts in the State of Delaware. As described below, this provision applies to suits brought to enforce any duty or liability created by the Securities Act or the Exchange Act, or any other claim for which there is exclusive federal or concurrent federal and state jurisdiction.
Our amended and restated certificate of incorporation provides that the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act. However, Section 22 of the Securities Act provides that federal and state courts have concurrent jurisdiction over lawsuits brought pursuant to the Securities Act or the rules and regulations thereunder. To the extent the exclusive forum provision restricts the courts in which claims arising under the Securities Act may be brought, there is uncertainty as to whether a court would enforce such a provision. Our amended and restated certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring or holding any interest in shares of our capital stock will be deemed to have notice of and to have consented to the foregoing provisions; provided, however, that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. This provision does not apply to claims brought under the Exchange Act.
We recognize that the forum selection clause in our amended and restated certificate of incorporation may impose additional litigation costs on shareholders in pursuing any such claims, particularly if the shareholders do not reside in or near the State of Delaware. Additionally, the forum selection clause in our amended and restated certificate of incorporation may limit our shareholders’ ability to bring a claim in a forum that they find favorable for disputes with us or our directors, officers, employees or agents, which may be costlier and may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our shareholders, although such shareholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. The Court of Chancery of the State of Delaware may also reach different judgments or results than would other courts, including courts where a shareholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our shareholders.
If securities or industry analysts do not publish research or publish misleading or unfavorable research about our business, our stock price and trading volume could decline.
The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts that currently cover our common stock downgrades our stock or publishes misleading or unfavorable research about our business, our stock price would likely decline. If one or more of the analysts ceases coverage of our common stock or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our common stock price or trading volume to decline.
10


USE OF PROCEEDS
All shares of our common stock sold pursuant to this prospectus will be offered and sold by the selling shareholder. We will not receive any proceeds from such sale.
One or more debt-for-equity exchange parties (or one or more of their respective affiliates) would be the selling shareholder and either such debt-for-equity exchange parties or one or more of their respective affiliates would also act as an underwriter in such offering. Because the selling shareholder in any such offering would be an underwriter or an affiliate of an underwriter, if such selling shareholder receives 5% or more of the net proceeds of such offering, such selling shareholder (in its capacity as an underwriter) or such affiliate of such selling shareholder acting as an underwriter would be deemed to have a “conflict of interest” under FINRA Rule 5121. Accordingly, any such offering would be conducted in compliance with the requirements of Rule 5121. The appointment of a “qualified independent underwriter” would not be required in connection with any such offering because a “bona fide public market,” as defined in Rule 5121, exists for our common stock. In accordance with FINRA Rule 5121, any such underwriter with a conflict of interest would not confirm any sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder. See “Plan of Distribution (Conflicts of Interest).”

MARKET PRICE OF OUR COMMON STOCK AND DIVIDEND POLICY
Market Price of Our Common Stock
Our common stock is listed on the NYSE under the symbol “AMTM”.
On March 7, 2025, the closing price of our common stock as reported on the NYSE was $19.99 per share. As of February 27, 2025, there were 243,303,999 shares of our common stock outstanding, held of record by 2,312 holders.
Dividend Policy
We do not expect to declare or pay any cash dividends on our common stock. Any future determination as to the timing, declaration, amount and payment of any dividends will be within the discretion of our Board of Directors, and will depend upon, among other things, our financial condition, earnings, capital requirements of our operating subsidiaries, regulatory constraints, industry practice, ability to access capital markets, and other factors deemed relevant by our Board of Directors, including legal and contractual restrictions. Moreover, if we determine to pay any dividends in the future, we cannot assure you that we will continue to pay such dividends or the amount of such dividends.

SELLING SHAREHOLDER
All of the shares of our common stock being registered under this prospectus are currently beneficially owned by Jacobs. However, any offers and sales pursuant to this prospectus will involve a debt-for-equity exchange pursuant to which one or more debt-for-equity exchange parties will become the selling shareholder hereunder, as described below.
Jacobs or one or more of its subsidiaries will dispose of any or all of our common stock that it holds after the RMT Transaction (including shares of our common stock received pursuant to any post-closing adjustment to the merger consideration) through one or more distributions on a pro rata basis to Jacobs’ shareholders or exchanges for debt in accordance with the terms of the IRS private letter ruling received by Jacobs in connection with the RMT Transaction. Jacobs and/or one or more of its subsidiaries and a debt-for-equity exchange party will enter into an exchange agreement with respect to such shares exchanged for debt obligations of Jacobs. Pursuant to such exchange agreement, the debt-for-equity exchange parties, as principals for their own accounts, will exchange debt obligations of JEG or certain of its subsidiaries held by the debt-for-equity exchange parties for shares of our common stock beneficially owned by Jacobs. Any offers and sales pursuant to this prospectus will involve such a debt-for-equity exchange. Under U.S. federal securities laws, the debt-for-equity exchange parties will be deemed to be the selling shareholder and underwriters with respect to any shares of our common stock that they acquire in connection with a debt-for-equity exchange and sell in an offering in connection therewith. We will amend or supplement this prospectus to name such debt-for-equity exchange party or parties prior to any such offers or sales. Jacobs may also be deemed a selling shareholder in any such offering solely for U.S. federal securities laws purposes. See “Plan of Distribution (Conflicts of Interest).”
Jacobs has, to our knowledge, sole investment power with respect to 19,464,174 shares of our common stock as of the date of this prospectus (including 1,216,511 shares of our common stock released from escrow to Jacobs pursuant to a post-closing adjustment to the merger consideration, but excluding the remaining 9,732,087 additional merger consideration shares, which remain held in escrow as of the date of this prospectus). Pursuant to the Registration Rights Agreement, Jacobs granted us, and caused each other direct or indirect subsidiary of Jacobs (including JEG) to the extent such subsidiary holds shares of our common stock retained in connection with the RMT Transaction to grant us, a proxy to vote the shares of our common stock owned by Jacobs and its subsidiaries in proportion to the votes cast by our other shareholders. As a result, Jacobs and its subsidiaries do not exercise voting power over any of the shares of our common stock that they beneficially own.
The information concerning the beneficial ownership of shares of common stock by Jacobs, as of February 27, 2025 included in this prospectus has been obtained from Jacobs and excludes additional shares of our common stock that may be received pursuant to any post-closing adjustment to the merger consideration. The shares beneficially owned by Jacobs reflected in the table below may be sold by the selling shareholder from time to time in one or more offerings described in this prospectus and any applicable prospectus supplement. The selling shareholder may sell all, some or none of the shares of common stock beneficially owned by it, and therefore we cannot estimate either the number or the percentage of shares of common stock that will be beneficially owned by Jacobs following any offering or sale hereunder.
As of February 27, 2025, 243,303,999 shares of our common stock are issued and outstanding, including 9,732,087 shares of our common stock in escrow pending release in connection with post-closing adjustments to the merger consideration, but excluding (i) 18,341,084 shares of common stock reserved for issuance under our 2024 Stock Incentive Plan and (ii) 2,644,588 shares of common stock available for purchase under our Employee Stock Purchase Plan. The percentage set forth in the table below is based on this share count.

DESCRIPTION OF CAPITAL STOCK
The following briefly summarizes the material terms of our capital stock contained in our amended and restated certificate of incorporation and amended and restated bylaws. These summaries do not describe every aspect of our capital stock and documents and are subject to all the provisions of our amended and restated certificate of incorporation and amended and restated bylaws and are qualified in their entirety by reference to these documents, which you should read for complete information on our capital stock. Our amended and restated certificate of incorporation and amended and restated bylaws are included as exhibits to the registration statement of which this prospectus forms a part. The following also summarizes certain relevant provisions of the DGCL. Amentum Holdings, Inc. and its wholly owned subsidiaries are referenced throughout as our “Company,” “we,” “us” or “our.”
Authorized Capital Stock
Our authorized capital stock consists of 1,000,000,000 shares of common stock, par value $0.01 per share, and 1,000,000 shares of preferred stock, par value $0.01 per share. Our Board of Directors may establish the rights and preferences of the preferred stock from time to time. As of February 27, 2025, approximately 243,303,999 shares of our common stock are issued and outstanding and no shares of our preferred stock are issued and outstanding.
Common Stock
Voting Rights. Holders of our common stock are entitled to one vote per share on all matters submitted to a vote of shareholders, including the election of directors. Our common shareholders are not entitled to cumulative voting in the election of directors. Unless a different vote is required by applicable law, the rules of any stock exchange upon which our securities are listed, any regulation applicable to us or our securities, or specifically required by our amended and restated certificate of incorporation or amended and restated bylaws, if a quorum exists at any meeting of shareholders, shareholders will have approved any matter (other than the election of directors, which is described below) if a majority of the voting power of shareholders present in person or represented by proxy at the meeting and entitled to vote on such matter are in favor of such matter. Subject to the rights of the holders of any future series of preferred stock to elect directors under specified circumstances, if a quorum exists at any meeting of shareholders, shareholders will have approved the election of a director if a majority (or, if the number of nominees exceeds the number of directors to be elected at such meeting of shareholders, a plurality) of the votes cast on such matter by shareholders present in person or represented by proxy at such meeting and entitled to vote for the election of such director are in favor of such election.
Dividend Rights. Subject to preferences that may be applicable to any shares of preferred stock that we may designate and issue in the future, holders of our common stock are entitled to receive ratably such dividends as may be declared by our Board of Directors out of funds legally available therefor if our Board of Directors, in its discretion, determines to issue dividends and only then at the times and in the amounts that our Board of Directors may determine.
Liquidation Rights. Upon liquidation, dissolution or winding up of our Company, holders of our common stock are entitled to receive their ratable share of the net assets of our Company available after payment of all debts and other liabilities, subject to the prior preferential rights and payment of liquidation preferences, if any, of any outstanding shares of preferred stock.
Other Matters. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.
Preferred Stock
Our Board of Directors has the authority, subject to the limitations imposed by Delaware law, the NYSE’s listing rules and our amended and restated certificate of incorporation, without any further vote or action by our
15


shareholders, to issue preferred stock in one or more series and to fix the designations, powers, preferences, limitations and relative, participating, optional and other special rights of the shares of each series, including:
dividend rates;
conversion rights;
designation and voting rights;
terms of repurchase or redemption, including any restrictions on repurchase or redemption as a result of arrearage in the payment of dividends or sinking fund installments;
liquidation preferences;
sinking fund terms; and
the number of shares constituting each series.
Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of our common stock. Holders of shares of preferred stock may be entitled to receive a preference payment in the event of our liquidation, dissolution or winding-up before any payment is made to the holders of shares of our common stock.
Our Board of Directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock, and may adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock.
There are no current agreements or understandings with respect to the issuance of preferred stock, and our Board of Directors has no present intentions to issue any shares of preferred stock.
Certain Anti-Takeover Provisions of Our Amended and Restated Certificate of Incorporation, Our Amended and Restated Bylaws, the Stockholders Agreement and Delaware Law
Certain provisions of our amended and restated certificate of incorporation, our amended and restated bylaws, our Stockholders Agreement and the DGCL may discourage or make more difficult a takeover attempt that a shareholder might consider to be in his, her or its best interest. These provisions may also adversely affect the prevailing market price for shares of our common stock. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unsolicited proposal to acquire or restructure us, which may result in an improvement of the terms of any such proposal in favor of our shareholders, and outweigh any potential disadvantage of discouraging those proposals.
Authorized but Unissued Shares of Capital Stock
Our authorized but unissued shares of common stock and preferred stock are available for future issuance without shareholder approval, subject to the applicable provisions of the DGCL and rules of the NYSE.
These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans.
One of the effects of the existence of authorized but unissued common stock or preferred stock may be to enable our Board of Directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of our Company by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management and possibly deprive our shareholders of opportunities to sell their shares of common stock at a price higher than the prevailing market price.
16


Board Vacancies and Board Size
Except as set forth below, our amended and restated certificate of incorporation and amended and restated bylaws provide that any vacancies, including any newly created directorships, on our Board of Directors will be filled by the affirmative vote of the majority of the remaining directors then in office, even if such directors constitute less than a quorum, or by a sole remaining director (other than directors elected by the holders of any series of preferred stock). In addition, the number of directors constituting our Board of Directors are permitted to be set only by a resolution adopted by the affirmative vote of at least 80% of the members of the Board of Directors at such time; provided that the number of directors will not be fewer than three and not greater than 21 directors as is provided by our amended and restated certificate of incorporation. These provisions prevent a shareholder from increasing the size of our Board of Directors and then gaining control of our Board of Directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our Board of Directors and promotes continuity of management.
If at any time prior to the second anniversary of the Closing Date, the Executive Chair becomes unable to serve as the Executive Chair of the Board of Directors, a majority of the directors initially identified by Jacobs for election or appointment to the Board of Directors (each, a “Jacobs Designated Director”) then serving on the Nominating and Governance Committee may, by affirmative vote, select another member of the Board of Directors to serve as a non-executive Chair of the Board of Directors until the second anniversary of the Closing Date.
No Cumulative Voting
Under the DGCL, shareholders are not entitled to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation does not provide for cumulative voting.
Director Removal
Except as set forth below, our amended and restated certificate of incorporation provides that shareholders may remove directors with or without cause by the affirmative vote of holders of at least a majority of the voting power of our then outstanding capital stock. Prior to September 27, 2025 (or, in the case of the Executive Chair of the Board of Directors, September 27, 2026), Sponsor Stockholder shall vote its Company common stock in favor of all Jacobs Designated Directors and shall not seek, propose or vote its Company common stock in favor of the removal of any Jacobs Designated Director from the Board, other than for cause.
Shareholder Action and Special Meetings of Shareholders
Our amended and restated certificate of incorporation provides that our shareholders may not take action by written consent, but may only take action at annual or special meetings of our shareholders. As a result, a holder controlling a majority of our capital stock is not able to amend our amended and restated bylaws or remove directors without holding a meeting of our shareholders called in accordance with our amended and restated certificate of incorporation. Our amended and restated certificate of incorporation further provides that special meetings of our shareholders may be called only by a majority of our Board of Directors, thus prohibiting a shareholder from calling a special meeting. These provisions may delay the ability of our shareholders to force consideration of a proposal or for shareholders controlling a majority of our capital stock to take any action, including the removal of directors.
Advance Notice Requirements for Shareholder Proposals and Director Nominations
Our amended and restated bylaws establish advance notice procedures with respect to shareholder proposals and the nomination of candidates for election as directors at our annual meeting of shareholders, and also specify certain procedural requirements regarding the form, content and timing of such notice. Specifically, such notice must be in proper written form and must set forth certain information, as required under our amended and restated bylaws, related to the shareholder giving the notice, the beneficial owner (if any) on whose behalf the nomination is made as well as their control persons and information about the proposal or nominee for election to our Board of Directors. These provisions might preclude our shareholders from bringing matters before our annual meeting of shareholders or from making nominations for directors at our annual meeting of shareholders if the proper procedures are not
17


followed. We expect that these provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.
Amendment of Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws
Any amendment, alteration, rescission or repeal of our amended and restated bylaws by our shareholders requires the affirmative vote of the Board of Directors or holders of at least a majority of voting power of all the then outstanding shares of stock entitled to vote thereon, voting together as a single class.
The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation or bylaws, unless the corporation’s certificate of incorporation requires a greater percentage. Our amended and restated certificate of incorporation provides that certain specified provisions in our amended and restated certificate of incorporation may be amended, altered, rescinded or repealed only by the affirmative vote of the holders of at least 66 2/3% of voting power of all the then outstanding shares of our stock entitled to vote thereon, voting together as a single class.
Our Stockholders Agreement prohibits, until September 27, 2027, amendments to our amended and restated certificate of incorporation and bylaws to provide the shareholders of our Company with proxy access rights, unless we receive the prior written consent of Sponsor Stockholder.
Section 203 of the Delaware General Corporation Law
We are subject to the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for three years following the time that such shareholder became an interested stockholder, unless:
prior to such time the board of directors of the corporation approved either the business combination or the transaction that resulted in the shareholder becoming an interested stockholder;
upon consummation of the transaction that resulted in the shareholder becoming an interested stockholder, the interested shareholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned by (i) persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
at or subsequent to such time the business combination is approved by the board of directors and authorized at an annual or special meeting of shareholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.
In general, Section 203 of the DGCL defines a “business combination” to include mergers, asset sales and other similar transactions and an “interested stockholder” as a person who, together with affiliates and associates, beneficially owns, or within three years did beneficially own, 15% or more of the corporation’s outstanding voting stock. We have not “opted out” of, and are subject to, Section 203 of the DGCL and these provisions may have the effect of delaying, deferring or preventing changes in control of us.
Certain Provisions of Our Amended and Restated Certificate of Incorporation and Delaware Law
Dissenters’ Rights of Appraisal and Payment
Under the DGCL, with certain exceptions, our shareholders have appraisal rights in connection with a merger or consolidation in which we are a constituent entity. Pursuant to the DGCL, shareholders who properly demand and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery, plus interest, if any, on the amount
18


determined to be the fair value, from the effective time of the merger or consolidation through the date of payment of the judgment.
Shareholders’ Derivative Actions
Under the DGCL, any of our shareholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the shareholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such shareholder’s stock thereafter devolved by operation of law. To bring such an action, the shareholder must otherwise comply with Delaware law regarding derivative actions.
Exclusive Forum
Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that (i) any derivative action or proceeding brought on behalf of our Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or shareholders to us or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of our amended and restated certificate of incorporation, amended and restated bylaws or the DGCL, or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware and (iv) any other action asserting a claim against us that is governed by the internal affairs doctrine, in each case, may be brought only in specified courts in the State of Delaware. As described below, this provision does not apply to suits brought to enforce any duty or liability created by the Securities Act or the Exchange Act, or any other claim for which there is exclusive federal or concurrent federal and state jurisdiction.
Our amended and restated certificate of incorporation also provides that the federal district courts of the United States of America are the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act. However, Section 22 of the Securities Act provides that federal and state courts have concurrent jurisdiction over lawsuits brought pursuant to the Securities Act or the rules and regulations thereunder. To the extent the exclusive forum provision restricts the courts in which claims arising under the Securities Act may be brought, there is uncertainty as to whether a court would enforce such a provision. Our amended and restated certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring or holding any interest in shares of our capital stock is deemed to have notice of and to have consented to the foregoing provisions; provided, however, that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. This provision does not apply to claims brought under the Exchange Act.
We recognize that the forum selection clause in our amended and restated certificate of incorporation may impose additional litigation costs on shareholders in pursuing any such claims, particularly if the shareholders do not reside in or near the State of Delaware. Additionally, the forum selection clause in our amended and restated certificate of incorporation may limit our shareholders’ ability to bring a claim in a forum that they find favorable for disputes with us or our directors, officers, employees or agents, which may be costlier and may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our shareholders, although such shareholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. The Court of Chancery of the State of Delaware may also reach different judgments or results than would other courts, including courts where a shareholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our shareholders.
Limitation of Liability and Indemnification of Directors and Officers
Our amended and restated certificate of incorporation includes provisions that limit the personal liability of our directors and officers, to the fullest extent permitted by the DGCL, for monetary damages for breach of their fiduciary duties as directors or officers. Such limitation does not apply to (i) any breach of a director or officer’s duty of loyalty to us or our shareholders, (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) a director for any unlawful payment of a dividend or unlawful stock repurchase or redemption, pursuant to Section 174 of the DGCL, (iv) any transaction from which such director or officer derived an improper personal benefit or (v) an officer in any action by or in the right of the corporation. These provisions have no effect on the availability of equitable remedies such as an injunction or rescission based on
19


a director’s breach of his or her duty of care. Any amendment to, or repeal of, these provisions do not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal.
Our amended and restated bylaws provide for indemnification, to the fullest extent permitted by the DGCL, of any person made or threatened to be made a party to any action, suit or proceeding by reason of the fact that such person is or was a director or officer of our Company, or, while a director or officer of our Company, at the request of our Company, serves or served as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or any other enterprise, against all expenses, liabilities and other losses reasonably incurred in connection with the defense or settlement of such action, suit or proceeding. In addition, we have entered into indemnification agreements with each of our directors pursuant to which we have agreed to indemnify each such director to the fullest extent permitted by the DGCL.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, we have been informed that in the opinion of the SEC such indemnification is against public policy and is therefore unenforceable.
Corporate Opportunity
Our amended and restated certificate of incorporation and Stockholders Agreement renounce any interest or expectancy in specified business opportunities or specified classes or categories of business opportunities, such that a director of our Company who also serves as a director, officer or employee of Amentum Equityholder or its affiliates may pursue certain business opportunities of which they become aware.
Listing
Our shares of common stock are listed on the NYSE under the symbol “AMTM.”
Transfer Agent and Registrar
The transfer agent and registrar for our common stock is Equiniti Trust Company, LLC.

PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)
The selling shareholder identified in this prospectus or any applicable prospectus supplement may offer, from time to time, up to an aggregate of 19,464,174 shares of our common stock. We are registering such shares, which are currently beneficially owned by Jacobs, under the terms of the Registration Rights Agreement. We will not receive any of the proceeds from the sale of such shares of our common stock by the selling shareholder. We are not selling any shares of our common stock under this prospectus.
All or a portion of the shares of our common stock described in this prospectus from time to time in the future may be sold directly to purchasers, or through underwriters or broker-dealers (or affiliates thereof), who may receive compensation in the form of discounts, concessions or commissions from the selling shareholder or the purchasers of the shares. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved.
Jacobs or one or more of its subsidiaries will dispose of any or all of our common stock that it holds after the RMT Transaction (including shares of our common stock received pursuant to any post-closing adjustment to the merger consideration) through one or more distributions on a pro rata basis to Jacobs’ shareholders or exchanges for debt in accordance with the terms of the IRS private letter ruling received by Jacobs in connection with the RMT Transaction. Jacobs and/or one or more of its subsidiaries and one or more debt-for-equity exchange parties will enter into an exchange agreement with respect to such shares exchanged for debt obligations of Jacobs. Pursuant to such exchange agreement, the debt-for-equity exchange parties, as principals for their own account, will exchange debt obligations of JEG or certain of its subsidiaries held by the debt-for-equity exchange parties for shares of our common stock beneficially owned by Jacobs. Any offers and sales pursuant to this prospectus will involve such a debt-for-equity exchange. Under U.S. federal securities laws, the debt-for-equity exchange parties will be deemed to be the selling shareholder and underwriters with respect to any shares of our common stock that they acquire in connection with a debt-for-equity exchange and sell in an offering in connection therewith. We will amend or supplement this prospectus to name such debt-for-equity exchange party or parties prior to any such offers or sales. Jacobs may also be deemed a selling shareholder in any such offering solely for U.S. federal securities laws purposes.
The shares of our common stock may be sold in one or more transactions on any national securities exchange or quotation service on which the shares may be listed or quoted at the time of sale, in the over-the-counter market or in transactions otherwise than on these exchanges or systems or in the over-the-counter market and in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions. Additionally, the selling shareholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. The selling shareholder may use any one or more of the following methods when selling shares:
on any national securities exchange or quotation service on which the shares may be listed or quoted at the time of sale, including the NYSE, in the case of the common stock;
in the over-the-counter market;
in transactions otherwise than on these exchanges or services or in the over-the-counter market;
through the writing or settlement of options or other hedging transactions, whether the options are listed on an options exchange or otherwise;
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
21


a debt-for-equity exchange;
privately negotiated transactions;
settlement of short sales entered into after the effective date of the registration statement of which this prospectus forms a part;
broker-dealers may agree with the selling shareholder to sell a specified number of such shares at a stipulated price per share;
a combination of any such methods of sale; and
any other method permitted pursuant to applicable law.
In addition, any securities that qualify for sale pursuant to Rule 144 or Regulation S under the Securities Act or under Section 4(a)(1) of the Securities Act may be sold under such rules or section rather than pursuant to this prospectus or a prospectus supplement, subject to any restriction on transfer contained in the Registration Rights Agreement.
If the selling shareholder uses an underwriter or underwriters for any offering, we will amend or supplement this prospectus to name them and set forth the terms of the offering and, except to the extent otherwise set forth in this prospectus or such prospectus supplement, as applicable, the selling shareholder will agree in an underwriting agreement to sell to the underwriters, and the underwriters will agree to purchase from the selling shareholder, the number of shares of our common stock set forth in this prospectus or such prospectus supplement, as applicable. It is expected that the underwriters’ obligation under the underwriting agreement will be conditioned on the consummation of the debt-for-equity exchange. Any such underwriters may offer the shares of our common stock from time to time for sale in one or more transactions on the NYSE, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices.
The underwriters may also propose initially to offer the shares of our common stock to the public at a fixed public offering price set forth on the cover page of the applicable prospectus supplement. The underwriters may be granted an option, exercisable for 30 days after the date of the applicable prospectus supplement, to purchase additional shares from the selling shareholder. In connection with an underwritten offering or debt-for-equity exchange, subject to certain exceptions, we may agree not to, and in such case would use reasonable best efforts to obtain agreements from our directors and executive officers not to, directly or indirectly, offer, transfer or pledge, or contract to transfer or pledge, any of our equity securities for a period of time after such offering. We will file a post-effective amendment to the registration statement of which this prospectus is a part to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
In connection with an underwritten offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A covered short position is a short position that is not greater than the amount of additional shares for which the underwriters’ option described above may be exercised. The underwriters may cover any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to cover the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option described above. Naked short sales are any short sales that create a short position greater than the amount of additional shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely
22


affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriters in the open market prior to the consummation of the offering.
The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.
The selling shareholder may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of our common stock in the course of hedging the positions they assume. The selling shareholder may also sell short the shares and deliver common stock to close out short positions, or loan or pledge the shares to broker-dealers that in turn may sell these shares. The selling shareholder may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus and the applicable prospectus supplement, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus and the applicable prospectus supplement. The selling shareholder also may transfer and donate the shares in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and the applicable prospectus supplement.
The aggregate proceeds to the selling shareholder from the sale of the shares of our common stock will be the purchase price of the shares less discounts and commissions, if any.
In order to comply with the securities laws of certain states, if applicable, the shares of our common stock must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless the shares are registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.
The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of the shares of our common stock pursuant to this prospectus and the applicable prospectus supplement and to the activities of the selling shareholder. In addition, we will make copies of this prospectus and the applicable prospectus supplement available to the selling shareholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the common stock to engage in market-making activities with respect to the common stock. All of the foregoing may affect the marketability of the common stock and the ability of any person or entity to engage in market-making activities with respect to the common stock.
There can be no assurance that the selling shareholder will sell any or all of the common stock registered pursuant to the registration statement of which this prospectus forms a part.
At the time a particular offering of the shares is made, an amendment or supplement to this prospectus will set forth the name of the selling shareholder, the aggregate amount of shares being offered and the terms of the offering, including, to the extent required, (1) the name or names of any underwriters, broker-dealers or agents, (2) any discounts, commissions and other terms constituting compensation from the selling shareholder and (3) any discounts, commissions or concessions allowed or reallowed to be paid to broker-dealers.
We have agreed to indemnify the selling shareholder against certain liabilities, including certain liabilities under the Securities Act. We expect to pay all reasonably incurred, out-of-pocket registration and filing fees, printing costs and fees and expenses of our and Jacobs’ legal counsel, accountants and certain other service providers. It is expected that the debt-for-equity exchange parties, agents or underwriters will pay their own expenses in connection with the registration and sale of the shares of our common stock covered by this prospectus and the applicable prospectus supplement, and no such expenses will be paid for or reimbursed directly by us or Jacobs. Agents and underwriters may be entitled to indemnification by us and the selling shareholder against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof.
23


Agents and underwriters and their respective affiliates may engage in transactions with, or perform services for us in the ordinary course of business for which they may receive customary fees and reimbursement of expenses.
The estimated offering expenses payable by us, in addition to any underwriting discounts and certain fees that will be paid by the selling shareholder, will be described in an amendment or supplement to this prospectus.
Conflicts of Interest
One or more debt-for-equity exchange parties (or one or more of their respective affiliates) would be the selling shareholder and either such debt-for-equity exchange parties or one or more of their respective affiliates would also act as an underwriter in such offering. Because the selling shareholder in any such offering would be an underwriter or an affiliate of an underwriter, if such selling shareholder receives 5% or more of the net proceeds of such offering, such selling shareholder (in its capacity as an underwriter) or such affiliate of such selling shareholder acting as an underwriter would be deemed to have a “conflict of interest” under FINRA Rule 5121. Accordingly, any such offering would be conducted in compliance with the requirements of Rule 5121. The appointment of a “qualified independent underwriter” would not be required in connection with any such offering because a “bona fide public market,” as defined in Rule 5121, exists for our common stock. In accordance with FINRA Rule 5121, any such underwriter with a conflict of interest would not confirm any sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS
The following discussion is a summary of certain U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our common stock offered by this prospectus, but does not purport to be a complete analysis of all potential U.S. federal income tax effects.
The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended, or the “Code”, Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service, or the “IRS”, in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our common stock.
This discussion is limited to Non-U.S. Holders that acquire our common stock in this offering and hold it as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:
U.S. expatriates and former citizens or long-term residents of the United States;
persons subject to the alternative minimum tax;
persons holding our common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;
banks, insurance companies, and other financial institutions;
brokers, dealers or traders in securities or other persons that elect to use a mark-to-market method of accounting for their holdings in our common stock;
“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;
partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);
tax-exempt entities or governmental entities;
persons deemed to sell our common stock under the constructive sale provisions of the Code;
persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation;
tax-qualified retirement plans;
“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds;
persons that at any time own (or are deemed to own) or have (or are deemed to have) owned more than five percent (by vote or value) of our common stock (except to the extent specifically set forth below); and
persons subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an applicable financial statement.
25


If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner in such partnership will depend on the status of the partner, the activities of such partnership and certain determinations made at the partner level. Accordingly, partnerships considering an investment in our common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.
THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER OTHER U.S. FEDERAL (INCLUDING ESTATE OR GIFT TAXES) TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.
Definition of a Non-U.S. Holder
For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of our common stock that is neither a “U.S. person” nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes. A “U.S. person” is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:
an individual who is a citizen or resident of the United States;
a corporation created or organized under the laws of the United States, any state thereof, or the District of Columbia;
an estate, the income of which is subject to U.S. federal income tax regardless of its source; or
a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.
Distributions
Any distributions of cash or property (other than certain distributions of our stock) on our common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes (generally any portion of a distribution that exceeds our current and accumulated earnings and profits), will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its common stock (determined separately with respect to each share of our common stock), but not below zero. Any excess will be treated as gain on the sale of our common stock as described below under “—Sale or Other Taxable Disposition.”
Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of our common stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty and the availability of a refund on any excess U.S. federal tax withheld.
If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, unless an applicable income tax treaty provides otherwise, the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder generally must furnish to the applicable withholding agent a valid IRS Form W-8ECI (or a suitable successor or substitute form), certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a
26


trade or business within the United States. Unless an applicable income tax treaty provides otherwise, any such effectively connected dividends generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates applicable to United States persons. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such Non-U.S. Holder’s effectively connected earnings and profits, as adjusted for certain items.
Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.
The foregoing discussion is subject to the discussion below under “Information Reporting and Backup Withholding” and “Additional Withholding Tax on Payments Made to Foreign Accounts.”
Sale or Other Taxable Disposition
Subject to the discussion below under “Information Reporting and Backup Withholding” and “Additional Withholding Tax on Payments Made to Foreign Accounts”, a Non-U.S. Holder will not be subject to U.S. federal income tax on any gain recognized upon the sale or other taxable disposition of our common stock unless:
the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);
the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or
our common stock constitutes a U.S. real property interest, or USRPI, by reason of our status as a U.S. real property holding corporation, or USRPHC, for U.S. federal income tax purposes.
Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates applicable to United States persons. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such Non-U.S. Holder’s effectively connected earnings and profits, as adjusted for certain items.
Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by certain U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.
If our common stock constitutes a USRPI, a Non-U.S. Holder will be subject to U.S. federal income tax on any gain recognized upon the sale or other taxable disposition of our common stock on a net income basis at the regular graduated rates applicable to United States persons. Our common stock will constitute a USRPI if we have been a USRPHC for U.S. federal income tax purposes at any time within the shorter of (x) the five-year period preceding the Non-U.S. Holder’s disposition of our common stock and (y) the Non-U.S. Holder’s holding period for the shares of our common stock. We have not determined whether we are, or have ever been, a USRPHC. Even if we are or become a USRPHC, however, as long as our common stock is “regularly traded” (as defined by applicable Treasury Regulations) on an established securities market, such common stock will be treated as USRPI only if the Non-U.S. Holder actually or constructively hold more than 5% of our common stock at any time during the shorter of the five-year period preceding the Non-U.S. Holder’s disposition of, or the Non-U.S. Holder’s holding period for, our common stock so disposed.
Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.
27


Information Reporting and Backup Withholding
Payments of dividends on our common stock will not be subject to backup withholding, provided the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, W-8ECI or other applicable IRS form, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our common stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld.
In addition, proceeds of the sale or other taxable disposition of our common stock within the United States or conducted through a non-U.S. office of a U.S. broker or a non-U.S. broker with specified connections to the United States generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above. Proceeds of a disposition of our common stock conducted through a non-U.S. office of a non-U.S. broker without specified connections to the United States generally will not be subject to backup withholding or information reporting.
Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.
Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.
Additional Withholding Tax on Payments Made to Foreign Accounts
Withholding taxes may be imposed under Sections 1471 to 1474 of the Code and the rules and regulations promulgated thereunder (commonly referred to as the Foreign Account Tax Compliance Act, or FATCA) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, shares of our common stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), regardless of whether such recipient is acting as an intermediary or a beneficial owner, unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.
Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our common stock. Although withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of stock on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.
Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our common stock.

Item 14.    Indemnification of Directors and Officers.
Delaware law authorizes corporations to limit or eliminate the personal liability of directors and officers to corporations and their shareholders for monetary damages for breaches of directors’ and officers’ fiduciary duties as directors or officers, as applicable, and our amended and restated certificate of incorporation includes provisions that limit the personal liability of our directors and officers, to the fullest extent permitted by the DGCL, for monetary damages for breach of their fiduciary duties as directors or officers. Such limitations do not apply to (i) any breach of a director or officer’s duty of loyalty to us or our shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director for any unlawful payment of a dividend or unlawful stock repurchase or redemption, pursuant to Section 174 of the DGCL, (iv) any transaction from which such director or officer derived an improper personal benefit or (v) an officer in any action by or in the right of the corporation. These provisions have no effect on the availability of equitable remedies such as an injunction or rescission based on a director’s breach of his or her duty of care. Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal.
In addition, our amended and restated bylaws provide for indemnification, to the fullest extent permitted by the DGCL, of any person made or threatened to be made a party to any action, suit or proceeding by reason of the fact that such person is or was a director or officer of Amentum, or, while a director or officer of Amentum, at the request of Amentum, serves or served as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or any other enterprise, against all expenses, liabilities and other losses reasonably incurred in connection with the defense or settlement of such action, suit or proceeding. Our bylaws also provide that we must indemnify and advance expenses to our directors and officers, subject to our receipt of an undertaking from the indemnified party as may be required under the DGCL.
In addition, we have entered into indemnification agreements with each of our directors pursuant to which we have agreed to indemnify each such director to the fullest extent permitted by the DGCL.
The limitation of liability and indemnification provisions included in our amended and restated certificate of incorporation, amended and restated bylaws and in indemnification agreements that we entered into with our directors may discourage shareholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. These provisions may also have the effect of reducing the likelihood of derivative litigation against our directors and officers, even though such an action, if successful, might otherwise benefit us and our shareholders. However, these provisions do not limit or eliminate our rights, or those of any shareholder, to seek
II-1


non-monetary relief such as an injunction or rescission in the event of a breach of a director’s duty of care. The provisions do not alter the liability of directors under the federal securities laws. In addition, your investment may be adversely affected to the extent that, in a class action or direct suit, we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. There is currently no pending material litigation or proceeding against any of our directors, officers, or employees for which indemnification is sought.
We currently maintain insurance policies which, within the limits and subject to the terms and conditions thereof, covers certain expenses and liabilities that may be incurred by directors and officers in connection with proceedings that may be brought against them as a result of an act or omission committed or suffered while acting as a director or officer of Amentum.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, we have been informed that in the opinion of the SEC such indemnification is against public policy and is therefore unenforceable.
Item 15.    Recent Sales of Unregistered Securities.
On November 17, 2023, we issued 100 shares of our common stock, $0.01 par value per share, to a subsidiary of Jacobs pursuant to Section 4(a)(2) of the Securities Act. We did not register the issuance of the issued shares under the Securities Act because such issuance did not constitute a public offering.
Item 16.    Exhibits and Financial Statement Schedules.
(a)Exhibits
The exhibits to the registration statement are listed in the Exhibit Index to this registration statement and are incorporated herein by reference.
(b)Financial statement schedules
All schedules have been omitted because either they are not required, are not applicable or the information is otherwise set forth in the financial statements and related notes thereto incorporated by reference herein.
Item 17.    Undertakings.
The undersigned registrant hereby undertakes:
(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
II-2


(2)That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
(5)For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
(6)For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The aforesaid [l] shares of Common Stock to be purchased by the Underwriters are herein called, collectively, the “Securities.”

(k)    Issuer Free Writing Prospectuses.

The Company represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Representative as an “issuer free writing prospectus,” as defined in Rule 433, and that it has complied and will comply with the applicable requirements of Rule
19


433 with respect thereto, including timely filing with the Commission where required, legending and record keeping.

SECTION 4.    Payment of Expenses.

SECTION 6.    Indemnification.
(a)    Indemnification by the Company. The Company agrees to indemnify and hold harmless each Underwriter, and their respective affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, Jacobs, its affiliates and each person, if any, who controls Jacobs within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the Selling Shareholder, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other reasonable expenses incurred and documented in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) or (B) in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission from any preliminary prospectus, Issuer Free Writing Prospectus, Prospectus or any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Information, the Selling Shareholder Information or the Jacobs Information.
(b)    Indemnification by Jacobs. Jacobs agrees to indemnify and hold harmless each Underwriter, its affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the Company, its affiliates, each of their respective directors and officers and each person, if any who, controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, to the extent and in the manner set forth in clause (a) above; provided that Jacobs shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration
23


Statement, any preliminary prospectus, the General Disclosure Package, the Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Jacobs Information.
(c)    Indemnification by Selling Shareholder. The Selling Shareholder agrees to indemnify and hold harmless each Underwriter, its affiliates and selling agents and each person, if any, who controls any Underwriter, within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, Jacobs, its affiliates, and each person, if any, who controls Jacobs within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the Company, its affiliates, each of their respective directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, to the extent and in the manner set forth in clause (a) above; provided that the Selling Shareholder shall be liable only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any preliminary prospectus, the General Disclosure Package, the Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Selling Shareholder Information; provided, further, that the liability under this subsection of the Selling Shareholder shall be limited to an amount equal to the underwriting commissions and discounts, but before expenses, in connection with the offering.
(d)    Indemnification by Underwriters. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its affiliates, each of their respective directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, Jacobs, its affiliates and each person, if any, who controls Jacobs within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the Selling Shareholder and each person, if any, who controls the Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the indemnity set forth in subsection (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with the Underwriter Information.
(e)    Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to paragraph (a), (b), (c) or (d) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a), (b), (c) or (d) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a), (b), (c) or (d) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person, upon request of the Indemnified Person, thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 6 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such proceeding and shall pay the reasonable and documented fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually
24


agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such reasonable and documented fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm shall be designated in writing by such Indemnified Person. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by the Indemnifying Person of such request and more than 30 days after receipt of the proposed terms of such settlement and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.
(f)    Other Agreements with Respect to Indemnification. The provisions of this Section shall not affect any other agreement among any of the Company, Jacobs and the Selling Shareholder with respect to indemnification, including the Registration Rights Agreement.
SECTION 7.    Contribution.
(a)    If the indemnification provided for in paragraph (a), (b), (c) or (d), as applicable, of Section 6 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the Company, in one regard, Jacobs, in the second regard, the Selling Shareholder, in the third regard, and the Underwriters, in the fourth regard, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company, in one regard, Jacobs, in the second regard, the Selling Shareholder, in the third regard, and the Underwriters, in the fourth regard, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, in one regard, Jacobs, in the second regard, the Selling Shareholder, in the third regard or
25


the Underwriters, in the fourth regard, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.
(b)    The Company, Jacobs, the Selling Shareholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (a) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (a) above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, (i) in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) in no event shall the Selling Shareholder be required to contribute any amount in excess of the amount by which the discount received by it or its affiliate, as applicable, in its or its affiliate’s capacity as an Underwriter hereunder, exceeds any damages which the Selling Shareholder has otherwise been required to pay. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.
(c)    The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.
For purposes of this Section 7, the respective affiliates, directors and officers of the Underwriters and each person, if any, who-controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each of the affiliates of the Company, each of the directors and officers of the Company and its affiliates and each person, if any, who controls the Company, Jacobs or the Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, shall have the same rights to contribution as the Company, Jacobs or the Selling Shareholder, as the case may be. The Underwriters respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Securities set forth opposite their respective names in Schedule A hereto and not joint.
The provisions of this Section shall not affect any other agreement among any of the Company, Jacobs and the Selling Shareholder with respect to contribution.
SECTION 8.    Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries, Jacobs or the Selling Shareholder submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its affiliates or selling agents, any person controlling any Underwriter, its officers or directors, any person controlling the Company or any person controlling Jacobs or the Selling Shareholder and (ii) delivery of and payment for the Securities.

26


SECTION 9.    Termination of Agreement.
(a)    Termination. The Representative may terminate this Agreement, by notice to the Company, Jacobs and the Selling Shareholder, at any time at or prior to the Closing Time (i) there has been, in the judgment of the Representative, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or (iv) if trading generally on the NYSE MKT or the New York Stock Exchange or in the Nasdaq Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.
(b)    Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 14, 15, 16 and 17 shall survive such termination and remain in full force and effect.
SECTION 10.    Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:
(i)    if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or
(ii)    if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.
No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.
27


In the event of any such default which does not result in a termination of this Agreement, either the (i) Representative or (ii) the Company and the Selling Shareholder shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Re:    Proposed Public Offering of Common Stock of Amentum Holdings, Inc.
Dear Ladies and Gentlemen:
The undersigned, a securityholder and/or an officer and/or a director, as applicable, of Amentum Holdings, Inc., a Delaware corporation (the “Company”), understands that BofA Securities, Inc. (in its capacity as representative of the underwriters, the “Representative”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company, Jacobs Engineering Group Inc. and the Selling Shareholder listed on Schedule B to the Underwriting Agreement providing for the public offering (the “Public Offering”) of shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”). In recognition of the benefit that the Public Offering will confer upon the undersigned as a securityholder and/or an officer and/or a director, as applicable, of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, during the period beginning on the date of the Underwriting Agreement and ending on the date that is 90 days from the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of the Representative (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (“Other Securities”), whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (including, without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”) and securities which may be issued upon exercise of a stock option or warrant) (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-Up Securities, or file, cause to be filed or cause to be confidentially submitted any registration statement in connection therewith, under the Securities Act of 1933, as amended (the “Securities Act”) (ii) enter into any hedging, swap, loan or any other agreement or any transaction (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward or any other derivative transaction or instrument, however described or defined) that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such hedging, swap, loan or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise, or (iii) publicly disclose the intention to do any of the foregoing described in clauses (i) and (ii) above.
7


Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of the Representative in any one or more of the following transactions:
(i)    as a bona fide gift or gifts, including, without limitation, to a charitable organization or educational institution, or for bona fide estate planning purposes;
(ii)    upon death or by will, testamentary document or intestate succession;

(vi)    to any immediate family member of the undersigned or any trust, partnership, limited liability company or other entity for the direct or indirect benefit of the undersigned or one or more immediate family members of the undersigned (for purposes of this lock-up agreement (this “Agreement”), “immediate family” of the undersigned shall mean any relationship by blood, current or former marriage, domestic partnership or adoption, not more remote than the first cousin of the undersigned);
(vii)    to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (vi) above;
(viii)    if the undersigned is a corporation, partnership, limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust or other business entity that is an affiliate (as defined in Rule 405 promulgated under the Securities Act) of the undersigned, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned or affiliates of the undersigned (including, for the avoidance of doubt, where the undersigned is a partnership or a control person of a partnership, to such partnership’s general partner or a successor partnership or fund, or any other funds managed by such partnership), (B) as part of a distribution, transfer or disposition to current or former general or limited partners, limited liability company members, beneficiaries, stockholders of the undersigned or holders of similar equity interests in the undersigned, (C) to any wholly owned subsidiary of the undersigned or (D) if a transferee referred to under clauses (viii)(A) or (B) above is not a natural person, any director or indirect partner, member, beneficiary, stockholder equityholder of such transferee until the Lock-Up Securities come to be held by a natural person;
(ix)    to the Company upon the undersigned’s death, disability or termination of employment or other service relationship with the Company; provided that the Common Stock or Other Securities received under this clause shall remain subject to the restrictions contained in this Agreement;
8


(x)    (A) the receipt by the undersigned from the Company of any Common Stock or Other Securities upon the exercise of options, settlement of restricted stock units or other equity awards or the exercise of warrants which are outstanding as of the date of the final prospectus relating to the Public Offering (the “Prospectus”) pursuant to plans or programs disclosed in the Prospectus, or (B) the transfer of any Common Stock or Other Securities to the Company upon a vesting or settlement event of the Company’s restricted stock units or other equity awards, or upon the exercise of options or warrants to purchase the Company’s securities on a “cashless” or “net exercise” basis to the extent permitted by the instruments representing such securities, options, restricted stock units or other equity awards, or warrants (and solely to the extent necessary to cover the exercise price and the amount needed for the payment of taxes, including estimated taxes, due as a result of such vesting, settlement or exercise whether by means of a “net settlement” or otherwise) so long as such “cashless” exercise or “net exercise” is effected solely by the surrender of outstanding securities, options, restricted stock units or other equity awards, or warrants (or the Common Stock or Other Securities issuable upon the exercise or settlement thereof) to the Company and the Company’s cancellation of all or a portion thereof to pay the exercise price and/or withholding tax and remittance obligations; provided that (x) the Common Stock or Other Securities received upon exercise or settlement of the security, option, restricted stock unit or other equity award, or warrant are subject to the terms of this Agreement, and (y) that in the case of either (A) or (B), any public announcement or filing under Section 16(a) of the Exchange Act or any other public filing or disclosure shall clearly indicate that (i) the filing relates to the circumstances described in (A) or (B), as the case may be, (ii) no Lock-Up Securities were sold by the reporting person and (iii) the Lock-Up Securities retained by the undersigned after such “cashless” or “net exercise” are subject to a lock-up agreement with the underwriters of the Public Offering;
(xi)    the transfer of Common Stock or Other Securities in connection with a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the board of directors of the Company and made to all holders of Common Stock involving a Change of Control (as defined below), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Lock-Up Securities owned by the undersigned shall remain subject to the restrictions contained in this Agreement. For the purposes of this clause (xi), “Change of Control” shall mean the consummation of any bona fide third-party tender offer, merger, consolidation or similar transaction, in one transaction or a series of related transactions, the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of the total voting power of the voting stock of the Company (or the surviving entity);
(xii)    any transfer of shares of Common Stock or Other Securities to the Company pursuant to arrangements under which the Company has the option to repurchase such shares or other securities or a right of first refusal with respect to such securities; provided that the Common Stock or Other Securities received under this clause shall remain subject to the restrictions contained in this Agreement;
(xiii)    establishing, facilitating the establishment of or amending a trading plan pursuant to Rule 10b5-1 under the Exchange Act, provided that (i) such plan does not provide for the transfer of Lock-Up Securities during the Lock-Up Period and (ii) to the extent a public

(xiv)    for the avoidance of doubt, confidential or non-public submissions to the Commission of any registration statements under the Securities Act if no public announcement of such confidential or non-public submission shall be made; and
(xv)    transactions as permitted by the prior written consent of the Representative;
provided that in the case of any transfer, distribution or other disposition pursuant to clause (i) and clauses (v) through (viii) above, (a) the Representative receives a signed lock-up agreement in the form of this Agreement for the balance of the Lock-Up Period from each donee, devisee, trustee, distributee, or transferee, as the case may be, (b) any such transfer shall not involve a disposition for value and (c) any required filing during the Lock-Up Period with the Commission on Form 4 or Form 5 in accordance with Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) shall clearly indicate in the footnotes thereto that the Lock-Up Securities retained by the transferee, donee or distribute are subject to a lock-up agreement with the underwriters of the Public Offering; and
provided further that in the case of any transfer pursuant to clauses (iii), (iv) and (xii), any filing in accordance with Section 16(a) of the Exchange Act made during the Lock-Up Period shall clearly indicate that the transfer is by operation of law, court order, or in connection with a divorce settlement, or a repurchase by the Company, as the case may be;
Furthermore, notwithstanding the foregoing, the undersigned may sell or transfer Common Stock or Other Securities purchased by the undersigned on the open market following the date of the Prospectus; provided that (i) such sales or transfers are not required to be reported during the Lock-Up Period with the Commission on Form 4 or Form 5 in accordance with Section 16(a) of the Exchange Act, and (ii) the undersigned does not otherwise voluntarily effect any such public filing or report regarding such sales or transfers during the Lock-Up Period. [The undersigned may exchange or dispose of shares of Common Stock in connection with the Public Offering pursuant to the terms of the Exchange Agreement.]1
[Notwithstanding anything to the contrary herein, the undersigned may freely transfer the Lock-Up Securities or any other shares of Common Stock held by the undersigned without the prior written consent of the Representative in connection with any pro rata distribution of Common Stock by Jacobs Engineering Group Inc. or Jacobs Solutions Inc. to its shareholders; provided that such transfer is not a disposition of Common Stock for value.]2
The undersigned acknowledges and agrees that the underwriters have neither provided any recommendation or investment advice nor solicited any action from the undersigned with respect to the Public Offering of the Common Stock and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the underwriters may be required or choose to provide certain Regulation Best Interest and Form CRS disclosures to you in connection with the Public Offering, the

underwriters are not making a recommendation to you to enter into this Agreement and nothing set forth in such disclosures is intended to suggest that any underwriter is making such a recommendation.
[If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Exchange Act), other than a natural person, entity or “group” (as described above) that has executed a Lock-Up Agreement in substantially the same form as this Lock-Up Agreement, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.]3
The undersigned hereby represents and warrants that the undersigned has full power, capacity and authority to enter into this Agreement. The undersigned understands that the Company and the underwriters are relying upon this Agreement in proceeding toward the consummation of the Public Offering.
