Amentum Reports Fiscal Year 2024 Results and Affirms its Fiscal Year 2025 Guidance

Strong finish to Fiscal Year 2024 including a successful public market debut
GAAP Revenues of $8.4 billion, 7% growth; GAAP Net Loss of $82 million
Pro Forma Revenues of $13.9 billion, 4% growth
Pro Forma Net Income of $32 million; Pro Forma Adjusted EBITDA of $1,052 million, up 7%
Amentum affirms its Fiscal Year 2025 Capital Markets Day financial guidance

CHANTILLY, VA., December 16, 2024 — Amentum Holdings, Inc. (“Amentum” or the “Company”) (NYSE: AMTM), a leading advanced engineering and technology company, today announced results for the fiscal year ended September 27, 2024, and affirmed its outlook for fiscal year 2025.

“We reported strong results for fiscal year 2024, delivering top-line and bottom-line growth,” commented Amentum Chief Executive Officer John Heller. “2024 was a significant year in our Company’s history, culminating in the merger of Amentum with Jacobs’ Critical Mission Solutions and Cyber & Intelligence businesses to create one of the strongest advanced engineering and technology companies in the industry. Today, over two months since the merger, we continue to be excited about the combined strength of these two historic businesses. We have transformed Amentum into a larger, more diversified company with broader customer reach and capabilities to deliver greater value to the world’s most complex challenges. In fiscal year 2025 we already see positive momentum and are confident in our outlook.”

1 – Non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Management believes that these non-GAAP measures provide another measure of Amentum’s results of operations and financial condition, including its ability to comply with financial covenants. See Unaudited Pro Forma Non-GAAP Financial Measures at the end of this press release for more information and a reconciliation of our selected reported results to these non-GAAP measures.

GAAP Results

GAAP revenues, which exclude Jacobs' Critical Mission Solutions and Cyber & Intelligence (CMS) businesses, increased 7% year-over-year driven by new contract awards and growth on existing programs. GAAP operating income increased primarily as a result of a non-cash impairment charge that was recognized during fiscal year 2023. Operating income also benefited from reduced intangible amortization expense and the higher revenue volume. GAAP net loss and diluted loss per share improved year-over-year due to the higher operating income and a gain on the acquisition of a controlling interest, partially offset by higher interest expense and a loss on extinguishment of debt.

Pro Forma and Non-GAAP Results

Pro forma revenues, which include the results of CMS prepared in accordance with the requirements of Article 11 of Regulation S-X, increased 4% year-over-year driven by new contract awards and growth on existing programs partially offset by the expected ramp-down of other historical programs. Pro Forma Adjusted EBITDA increased 7% year-over-year primarily due to the higher revenue volume and improved operating performance. Pro Forma Adjusted Net Income and Adjusted Diluted Earnings Per Share increased due to the higher operating income partially offset by increased tax expense.

Backlog and Contract Awards

As of September 27, 2024, the Company had a total backlog of $45.0 billion, compared with $26.8 billion a year ago, an increase of $18.2 billion primarily due the addition of backlog from CMS. Funded backlog as of September 27, 2024 was $7.6 billion.

Cautionary Note Regarding Forward Looking Statements

This release contains or incorporates by reference statements that relate to future events and expectations and, as such, 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,” “project,” “expect,” “anticipate,” “estimate,” “forecast,” “outlook,” “target,” “endeavor,” “seek,” “predict,” “intend,” “strategy,” “plan,” “may,” “could,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” or the negative thereof or variations thereon or similar terminology generally intended to identify forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including projections of financial performance; statements of plans, strategies and objectives of management for future operations; any statement concerning developments, performance or industry rankings relating to products or services; any statements regarding future economic conditions or performance; any statements of assumptions underlying any of the foregoing; and any other statements that address activities, events or developments that the Company intends, expects, projects, believes or anticipates will or may occur in the future.

Important factors that could cause actual results to differ materially from such plans, estimates or expectations include, among others: changes in U.S. or global economic, financial, business and political conditions, including changes to governmental budgetary priorities; our ability to comply with the various procurement and other laws and regulations; risks associated with contracts with governmental entities; reviews and audits by the U.S. government and others; changes to our professional reputation and relationship with government agencies; the occurrence of an accident or safety incident; the ability of the Company to control costs, meet performance requirements or contractual schedules, compete effectively or implement its business strategy; the ability of the Company to retain and hire key personnel, and retain and engage key customers and suppliers; the failure to realize the anticipated benefits of the 2024 transaction with Jacobs Solutions Inc.; potential liabilities associated with shareholder litigation or other settlements or investigations; evolving legal, regulatory and tax regimes; and other factors set forth under Item 1A, Risk Factors in the annual report on Form 10-K (the “Annual Report”), and from time to time in documents that we file with the SEC. The above list of factors is not exhaustive or necessarily in order of importance. For additional information on identifying factors that may cause actual results to vary materially from those stated in forward-looking statements, see the discussions under the section entitled “Risk Factors” in the Annual Report. Any forward-looking statement speaks only as of the date on which it is made, and we assume no obligation to update or revise such statement, whether as a result of new information, future events or otherwise, except as required by applicable law.

Pro Forma and Non-GAAP Measures

This release includes the presentation and discussion of pro forma financial information that incorporates the results of CMS prepared in accordance with the requirements of Article 11 of Regulation S-X. This release also includes the presentation and discussion of Pro Forma Adjusted EBITDA, Pro Forma Adjusted EBITDA Margin, Pro Forma Adjusted Net Income, Pro Forma Adjusted Diluted Earnings Per Share, and Free Cash Flow, which are not measures of financial performance under Generally Accepted Accounting Principles in the United States (“GAAP”). These pro forma and non-GAAP measures should be considered only as supplements to, and should not be considered in isolation or used as substitutes for, financial information prepared in accordance with GAAP. Management of the Company believes these pro forma and non-GAAP measures, when read in conjunction with the Company’s financial statements prepared in accordance with GAAP and, where applicable, the reconciliations herein to the most directly comparable GAAP measures, provide useful information to management, investors and other users of the Company’s financial information in evaluating operating results and understanding operating
3

trends by adjusting for the effects of items we do not consider to be indicative of the Company’s ongoing performance, the inclusion of which can obscure underlying trends. Additionally, management of the Company uses such measures in its evaluation of business performance, particularly when comparing performance to past periods, and believes these measures are useful for investors because they facilitate a comparison of financial results from period to period. The computation of pro forma and non-GAAP measures may not be comparable to similarly titled measures reported by other companies, thus limiting their use for comparability.

Definitions of applicable non-GAAP measures and reconciliations to the most directly comparable GAAP measures are provided elsewhere in this release.

UNAUDITED PRO FORMA NON-GAAP FINANCIAL MEASURES

The presentation and discussion of Pro Forma Adjusted EBITDA, Pro Forma Adjusted EBITDA Margin, Pro Forma Adjusted Net Income, Pro Forma Adjusted Diluted EPS, and Free Cash Flow are not measures of financial performance under Generally Accepted Accounting Principles in the United States (“GAAP”). These non-GAAP measures should be considered only as supplements to, and should not be considered in isolation or used as a substitute for, financial information prepared in accordance with GAAP. Management believes these non-GAAP measures, when read in conjunction with our consolidated financial statements prepared in accordance with GAAP and the reconciliations herein to the most directly comparable GAAP measures, provide useful information in assessing trends in our ongoing operating performance and may provide greater visibility in understanding the long-term financial performance of the Company. The computation of non-GAAP measures may not be comparable to similarly titled measures reported by other companies, thus limiting their use for comparability.
Pro Forma Adjusted EBITDA is defined as pro forma net (loss) income attributable to common shareholders, which incorporates the results of CMS prepared in accordance with the requirements of Article 11 of Regulation S-X, adjusted for pro forma interest expense and other, net, pro forma (benefit) provision for income taxes, pro forma depreciation and amortization, and excludes the following discrete pro forma items:
•Acquisition, transaction, and integration costs – Represents acquisition, transaction and integration costs, including severance, retention, and other adjustments related to acquisition and integration activities.
•Amortization of intangibles – Represents the amortization of intangible assets.
•Non-cash GAAP expense (gain) – Represents a non-cash goodwill impairment charge and a non-cash gain on acquisition of controlling interest.
•Loss on extinguishment of debt – Represents the write-off of debt discount and debt issuance costs as a result of debt modifications.
•Utilization of certain fair market value adjustments assigned in purchase accounting – Represents the periodic utilization of the fair market value adjustments assigned to certain equity method investments and non-controlling interests based on the remaining period of performance for the related contract.
•Share-based compensation – Represents non-cash compensation expenses recognized for share based arrangements.
Pro Forma Adjusted EBITDA Margin is defined as Pro Forma Adjusted EBITDA divided by Pro Forma Revenues.
Pro Forma Adjusted Net Income is defined as pro forma net (loss) income attributable to common shareholders, which incorporates the results of CMS prepared in accordance with the requirements of Article 11 of Regulation S-X, excluding the discrete pro forma items listed under Pro Forma Adjusted EBITDA and the related pro forma tax impacts.
Pro Forma Adjusted Diluted EPS is defined as Pro Forma Adjusted Net Income divided by pro forma diluted weighted average number of common shares outstanding.
Free Cash Flow is defined as GAAP cash flow provided by operating activities less purchases of property and equipment.
