1 – December 29, 2023 Revenues and Non-GAAP financial measures are presented on a pro forma basis to include the results of CMS prepared in accordance with the requirements of Article 11 of Regulation S-X.

2 – 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 increased 72% year-over-year primarily as a result of revenues from the combination with Jacobs' Critical Mission Solutions and Cyber & Intelligence (CMS) businesses. GAAP operating income increased as a result of the contribution from CMS, partially offset by increased intangible amortization expense. GAAP net income and diluted earnings per share improved year-over-year due to the higher operating income and lower interest expense.

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 2% year-over-year driven by growth in both Digital Solutions and Global Engineering Solutions. Pro Forma Adjusted EBITDA increased 3% year-over-year primarily due to the higher revenues and improved operating performance. Pro Forma Adjusted Net Income and Adjusted Diluted Earnings Per Share increased due to the higher operating profit partially offset by an increase in interest expense.

1 – December 29, 2023 Revenues and Non-GAAP financial measures are presented on a pro forma basis.

Digital Solutions revenues increased 1% year-over-year driven by new contract awards, partially offset by the expected ramp-down of other historical programs. Adjusted EBITDA also increased 1% year-over-year due to the higher revenues.

Global Engineering Solutions revenues increased 3% year-over-year driven by new contract awards and growth on existing programs. Adjusted EBITDA increased 4% year-over-year as a result of the higher revenues and improved operating performance.

Cash Flow Summary

During the quarter ended December 27, 2024, Amentum generated $110 million of net cash provided by operating activities and used $8 million and $16 million in investing and financing activities, respectively. Net cash provided by operating activities was driven by strong cash earnings, disciplined working capital management, and the timing of tax and interest payments. Investing activities included $8 million in capital expenditures, which resulted in quarterly free cash flow of $102 million. Financing activities consisted primarily of $13 million in distributions to non-controlling interests. As of December 27, 2024, Amentum had $522 million in cash and cash equivalents and $4.7 billion of debt.

Backlog and Contract Awards

As of December 27, 2024, the Company had total backlog of $45.2 billion, compared with $27.3 billion as of December 29, 2023, an increase of $17.9 billion primarily due to the acquisition of CMS. Funded backlog as of December 27, 2024 was $6.6 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 Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, 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"), each of which are pro forma when reporting for the fiscal quarter ended December 29, 2023. 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 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.

In addition to the above non-GAAP financial measures, the Company has included backlog, net bookings, and book-to-bill in this release. Backlog is an operational measure representing the estimated amount of future revenues to be recognized under negotiated contracts, and net bookings represent the change in backlog between reporting periods plus reported revenues for the period. Book-to-bill represents net bookings divided by reported revenues for the same period. We believe these metrics are useful for investors because they are an important measure of business development performance and are used by management to conduct and evaluate its business during its regular review of operating results.

UNAUDITED NON-GAAP FINANCIAL MEASURES

The presentation and discussion of Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, 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.

Adjusted EBITDA is defined as GAAP net income attributable to common shareholders adjusted for interest expense and other, net, provision for income taxes, depreciation and amortization, and excludes the following discrete 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.

Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenues.

Adjusted Net Income is defined as GAAP net income attributable to common shareholders excluding the discrete items listed under Adjusted EBITDA and the related tax impacts.

Adjusted Diluted EPS is defined as Adjusted Net Income divided by diluted weighted average number of common shares outstanding.
