Business and Basis of Presentation	Business V2X, Inc., an Indiana Corporation, formerly known as Vectrus, Inc. (Vectrus), is a leading provider of critical mission solutions and support to defense clients globally. The Company operates as one segment and delivers a comprehensive suite of integrated solutions and critical service offerings across the operations and logistics, aerospace, training and technology markets to national security, defense, civilian and international clients. Unless the context otherwise requires or unless stated otherwise, references in these notes to "V2X", "we," "us," "our," “combined company”, "the Company" and "our Company" refer to V2X, Inc. and all of its consolidated subsidiaries, taken together as a whole. Basis of Presentation The Company's quarterly financial periods end on the Friday closest to the last day of the calendar quarter (September 27, 2024 for the third quarter of 2024 and September 29, 2023 for the third quarter of 2023), except for the last quarter of the fiscal year, which ends on December 31. For ease of presentation, the quarterly financial statements included herein are described as three months ended. The unaudited interim Condensed Consolidated Financial Statements of V2X have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Accordingly, certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the U.S. (GAAP) have been omitted. These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. It is management’s opinion that these financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position and operating results. Revenue and net income for any interim period are not necessarily indicative of future or annual results. Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no material impact on the results of operations, financial position, or changes in shareholders’ equity.

RECENT ACCOUNTING STANDARDS UPDATE	RECENT ACCOUNTING STANDARDS UPDATE In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-07, Segment Reporting (Topic 280), to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. Amongst other amendments, the standard requires annual and interim disclosures of significant segment expenses that are regularly provided to the chief operating decision maker (CODM), and interim disclosures about a reportable segment’s profit or loss and assets that are currently required annually. This standard does not change how an entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of adoption of this standard on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09 Income Taxes (Topic 740) to improve income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of adoption of this standard on its consolidated financial statements.
