Q2’22 Earnings Presentation \ \ 2 Disclaimers FORWARD-LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act), and Section 27A of the Securities Act of 1933, as amended (the Securities Act), and the Private Securities Litigation Reform Act of 1995 and, as such, may involve risks and uncertainties. All statements included or incorporated by reference in this presentation, other than statements that are purely historical, are forward-looking statements. Forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “could,” “potential,” “continue” or similar terminology. These statements are based on the beliefs and assumptions of the management of the Company based on information currently available to management. Forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from the Company's historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to: the continued impact of COVID-19 and any variant strains thereof on the global economy and any current or future government mandated COVID-19 precautions, including mandatory vaccination; our ability to submit proposals for and/or win all potential opportunities in our pipeline; our ability to retain and renew our existing contracts; our ability to compete with other companies in our market; security breaches and other disruptions to our information technology and operation; our mix of cost-plus, cost-reimbursable, and firm-fixed-price contracts; maintaining our reputation and relationship with the U.S. government; protests of new awards; economic, political and social conditions in the countries in which we conduct our businesses; changes in U.S. or international government defense budgets; government regulations and compliance therewith, including changes to the DoD procurement process; changes in technology; intellectual property matters; governmental investigations, reviews, audits and cost adjustments; contingencies related to actual or alleged environmental contamination, claims and concerns; delays in completion of the U.S. government's budget; our success in extending, deepening, and enhancing our technical capabilities; our success in expanding our geographic footprint or broadening our customer base; our ability to realize the full amounts reflected in our backlog; impairment of goodwill; misconduct of our employees, subcontractors, agents, prime contractors and business partners; our ability to control costs; our level of indebtedness; terms of our credit agreement; inflation and interest rate risk; subcontractor performance; economic and capital markets conditions; our ability to maintain safe work sites and equipment; our ability to retain and recruit qualified personnel; our ability to maintain good relationships with our workforce; our teaming relationships with other contractors; changes in our accounting estimates; the adequacy of our insurance coverage; volatility in our stock price; changes in our tax provisions or exposure to additional income tax liabilities; risks and uncertainties relating to the Merger; risks and uncertainties relating to the Spin-off; changes in GAAP; and other factors described in Item 1A, “Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2021 and described in our other filings with the SEC. Use of Projections The financial projections, estimates and targets in this presentation are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond the Vectrus’ control. The assumptions and estimates underlying the projected, expected or target results are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the financial projections, estimates and targets. The inclusion of financial projections, estimates and targets in this presentation should not be regarded as an indication that Vectrus or its representatives considered or consider the financial projections, estimates and targets to be a reliable prediction of future events. Use of Non-GAAP Financial Measures This presentation includes certain non-GAAP financial measures that are not prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), including forward-looking measures, which may be different from non-GAAP financial measures used by other companies. These non- GAAP measures, and other measures that are calculated using these non-GAAP measures, are an addition, and not a substitute for or superior to measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to operating income, net income or any other performance measures derived in accordance with GAAP. We have provided additional information regarding these measures throughout in an Appendix to this presentation. Reconciliations of our forward-looking non-GAAP measures to the closest corresponding GAAP measures are not available without unreasonable efforts due to the uncertainties discussed above, which could have a potentially significant impact on our future results.

Q2’22 Earnings Presentation \ \ 22 Reconciliation Of Non-GAAP Measures/Non-GAAP Definitions This presentation includes certain non-GAAP financial measures, including EBITDA and Pro forma Adjusted EBITDA. These financial measures are not prepared in accordance with accounting principles generally accepted in the United States and may be different from non-GAAP financial measures used by other companies. Vectrus and Vertex believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends. These non-GAAP measures with comparable names should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP.  Adjusted EBITDA related to Vectrus refers to earnings before interest, taxes, depreciation and amortization, as adjusted for one- time non-recurring items (as applicable).  Adjusted EBITDA related to Vertex refers to earnings before interest, taxes, depreciation and amortization, as adjusted for one-time non-recurring items (as applicable). 2022 adjusted EBITDA includes $10 million in a discount received by Vertex from Raytheon under the transition services agreement governing Raytheon’s continued provision of services to the TTS Business. Adjusted EBITDA also includes synergy assumption from Vertex’s previously closed acquisition of the TTS Business. The synergies include $18 million of expected annual cost savings, partially phased in 2022 and 2023 and reaching full run-rate in 2024. Adjusted EBITDA does not include one-time integration costs or costs to achieve expected synergies.  Adjusted EBITDA related to the combined entity of Vectrus and Vertex refers to earnings before interest, taxes, depreciation and amortization, as adjusted for one-time non-recurring items (as applicable). 2022 adjusted EBITDA includes $10 million in a discount received by Vertex from Raytheon under the transition services agreement governing Raytheon’s continued provision of services to the TTS Business. Adjusted EBITDA also includes synergy assumption from Vertex’s previously closed acquisition of the TTS Business.
