Disclaimer Certain statements contained in this presentation constitute forward-looking statements within the meaning of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that do not directly relate to any historical or current fact. When used herein, words such as "expects," "anticipates," "believes," "seeks," "estimates," "plans," "intends," "future," "will," "would," "could," "can," "may," "target," "goal" and similar words are intended to identify forward-looking statements. Examples of forward-looking statements include, but are not limited to, statements we make concerning our expectations as to our future growth, prospects, financial outlook and business strategy, including our expectations for our fiscal year 2024 adjusted EBITDA, adjusted EPS, free cash flow conversion and net interest expense, as well as our expectations for how our Critical Missions Solutions ("CMS") and Cyber & Intelligence businesses are tracking against their forecasts, our plan to implement a cost optimization plan and increase return of capital to shareholders, our ability to reach our fiscal year 2024 strategic targets and our fiscal year 2024 effective tax rates, and any assumptions underlying any of the foregoing. Although such statements are based on management's current estimates and expectations, and/or currently available competitive, financial, and economic data, forward-looking statements are inherently uncertain, and you should not place undue reliance on such statements as actual results may differ materially. We caution the reader that there are a variety of risks, uncertainties and other factors that could cause actual results to differ materially from what is contained, projected or implied by our forward-looking statements. Such factors include uncertainties as to the structure and timing of the proposed transaction to spin off and merge with Amentum our CMS business and a portion of our Divergent Solutions business in a proposed transaction that is intended to be tax-free to stockholders for U.S. federal income tax purposes (hereinafter referred to as the "Separation Transaction"), the impact of the Separation Transaction on Jacobs' and the combined company's businesses if the transaction is completed, including a possible impact on Jacobs' credit profile, and a possible decrease in the trading price of Jacobs' and/or the combined company's shares, the possibility that the Separation Transaction, if completed, may not qualify for the expected tax treatment, the ability to obtain all required regulatory approvals, the possibility that closing conditions for the Separation Transaction may not be satisfied or waived, on a timely basis or otherwise, the risk that any consents or approvals required in connection with the Separation Transaction may not be received, the risk that the Separation Transaction may not be completed on the terms or in the time-frame expected by the parties, uncertainties as to our and our stockholders' respective ownership percentages of the combined company and the value to be derived from the disposition of Jacobs' stake in the combined company, unexpected costs, charges or expenses resulting from the Separation Transaction, business and management strategies and the growth expectations of the combined company, the inability of Jacobs and the combined company to retain and hire key personnel, customers or suppliers while the Separation Transaction is pending or after it is completed, and the ability of the Company to eliminate all stranded costs, as well as other factors related to our business, such as our ability to fully execute on our three-year corporate strategy, including our ability to invest in the tools needed to implement our strategy, competition from existing and future competitors in our target markets, our ability to achieve the cost-savings and synergies contemplated by our recent acquisitions within the expected time frames or to achieve them fully and to successfully integrate acquired businesses while retaining key personnel, the impact of any pandemic, and any resulting economic downturn on our results, prospects and opportunities, measures or restrictions imposed by governments and health officials in response to the pandemic, the timing of the award of projects and funding and potential changes to the amounts provided for under the Infrastructure Investment and Jobs Act, as well as other legislation related to governmental spending, any changes in U.S. or foreign tax laws, statutes, rules, regulations or ordinances that may adversely impact our future financial positions or results of operations, financial market risks that may affect the Company, including by affecting the Company's access to capital, the cost of such capital and/or the Company's funding obligations under defined benefit pension and postretirement plans, as well as general economic conditions, including inflation and the actions taken by monetary authorities in response to inflation, changes in interest rates, and foreign currency exchange rates, changes in capital markets, instability in the banking industry, or the impact of a possible recession or economic downturn on our results, prospects and opportunities, and geopolitical events and conflicts among others. The impact of such matters includes, but is not limited to, the possible reduction in demand for certain of our product solutions and services and the delay or abandonment of ongoing or anticipated projects due to the financial condition of our clients and suppliers or to governmental budget constraints or changes to governmental budgetary priorities; the inability of our clients to meet their payment obligations in a timely manner or at all; potential issues and risks related to a significant portion of our employees working remotely; illness, travel restrictions and other workforce disruptions that have and could continue to negatively affect our supply chain and our ability to timely and satisfactorily complete our clients' projects; difficulties associated with retaining and hiring additional employees; and the inability of governments in certain of the countries in which we operate to effectively mitigate the financial or other impacts of any future pandemics or infectious disease outbreaks on their economies and workforces and our operations therein. The foregoing factors and potential future developments are inherently uncertain, unpredictable and, in many cases, beyond our control. For a description of these and additional factors that may occur that could cause actual results to differ from our forward-looking statements see our Annual Report on Form 10-K for the year ended September 29, 2023, and in particular the discussions contained therein under Item 1 - Business; Item 1A - Risk Factors; Item 3 - Legal Proceedings; and Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations, and Part II, Item 1A - Risk Factors, in our most recently filed Quarterly Report on Form 10-Q, as well as the Company's other filings with the U.S. Securities and Exchange Commission. The Company is not under any duty to update any of the forward-looking statements after the date of this presentation to conform to actual results, except as required by applicable law.
