#### ABOUT THIS PROSPECTUS SUPPLEMENT
This document is in two parts. The first part is the prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying prospectus, which is part of a registration statement that we filed with the SEC using a "shelf" registration process. The accompanying prospectus provides you with more general information, some of which may not be applicable to this offering. Generally, when we refer to this prospectus supplement, we are referring to both parts of this document combined.

This prospectus supplement and the information incorporated by reference in this prospectus supplement adds to, updates and, where applicable, modifies and supersedes information contained or incorporated by reference in the accompanying prospectus. You should read this prospectus supplement together with the accompanying prospectus, as well as additional information described under the heading "Where You Can Find More Information" and "Incorporation of Certain Documents by Reference."

To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or any document incorporated by reference herein or therein filed prior to the date of this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement; provided that if any statement in one of these documents is inconsistent with a statement in another document having a later date — for example, a document incorporated by reference in this prospectus supplement — the statement in the document having the later date modifies or supersedes the earlier statement. Neither we, the underwriter nor the selling shareholder has authorized anyone to give you any other information, and we take no responsibility for any other information that others may give you. You must not rely upon any information not contained or incorporated by reference in this prospectus supplement, the accompanying prospectus or any applicable "free writing prospectus" prepared by us or on our behalf. This prospectus supplement and the accompanying prospectus do not constitute an offer to sell or a solicitation of an offer to buy any securities in any jurisdiction to any person to whom it is unlawful to make such offer or solicitation in such jurisdiction.

The information in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference herein and therein, and any applicable "free writing prospectus" prepared by us or on our behalf is accurate only as of their respective dates or as of any earlier date as of which such information is given, even though this prospectus supplement may be delivered, or our common stock may be sold under this prospectus supplement, on a later date. Our business, financial condition, results of operations, and prospects may have changed since those dates. You should carefully read the entire prospectus supplement, as well as the documents incorporated by reference in the prospectus supplement, the accompanying prospectus and any applicable "free writing prospectus" prepared by us or on our behalf before making an investment decision.

Unless the context otherwise requires or unless stated otherwise, references in this prospectus supplement to "V2X," "we," "us," "our," "the Company" and "our Company" refer to V2X, Inc. and all of its consolidated subsidiaries.

#### Market and Industry Data
This prospectus supplement includes (and documents we incorporate by reference in this prospectus supplement and the accompanying prospectus may include) estimates regarding market and industry data. Unless otherwise indicated, information concerning our industry and the markets in which we operate, including our general expectations, market position, market opportunity and market size, are based on our management's knowledge and experience in the markets in which we operate, together with currently available information obtained from various sources, including publicly available information, industry reports and publications, surveys, our customers, trade and business organizations and other contacts in the markets in which we operate. Certain information is based on management estimates, which have been derived from third-party sources, as well as data from our internal research.

In presenting this information, we have made certain assumptions that we believe to be reasonable based on such data and other similar sources and on our knowledge of, and our experience to date in, the markets in which we operate. While we believe the estimated market and industry data included in this prospectus supplement (or documents we have incorporated by reference) is generally reliable, such

S-ii

[**TABLE OF CONTENTS**](#TOC)

information is inherently uncertain and imprecise. Market and industry data is subject to change and may be limited by the availability of raw data, the voluntary nature of the data gathering process and other limitations inherent in any statistical survey of such data. In addition, projections, assumptions and estimates of the future performance of the markets in which we operate are necessarily subject to uncertainty and risk due to a variety of factors, including those described in "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements." These and other factors could cause results to differ materially from those expressed in the estimates made by third parties and by us. Accordingly, you are cautioned not to place undue reliance on such market and industry data or any other such estimates.

#### RISK FACTORS
 *Investing in our common stock involves risk. Prior to making a decision about investing in our common stock, you should carefully consider the specific factors discussed below and under the heading "Risk Factors" in the accompanying prospectus, together with all of the other information contained or incorporated by reference in this prospectus supplement. You should also consider the risk factors related to our business and operations described in Part I, Item 1A, "Risk Factors" of our [Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC on February 23, 2026](https://www.sec.gov/ix?doc=/Archives/edgar/data/1601548/000160154826000015/vec-20251231.htm) (the "Annual Report on Form 10-K") and Part II, Item 1A of our [Quarterly Report on Form 10-Q for the quarterly period ended April 3, 2026 filed with the SEC on May 4, 2026](https://www.sec.gov/ix?doc=/Archives/edgar/data/1601548/000160154826000025/vec-20260403.htm), which are incorporated by reference herein. See "Where You Can Find More Information" in this prospectus supplement. If any of the following risks or uncertainties actually occur, our operations could be materially and adversely affected. In that case, the market price of our common stock could decline and you may lose all or a part of your investment. The risks and uncertainties we have described therein and below are not the only risks that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.* 

#### Risks Related to this Offering and Ownership of Our Common Stock

#### The trading price of our common stock may be volatile and could decline significantly and rapidly regardless of our operating performance.
The trading price of our common stock may be volatile and subject to wide fluctuations in response to many risk factors listed in this section and those included in our Annual Report on Form 10-K and subsequently filed quarterly reports on Form 10-Q and others beyond our control, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the number of shares of our common stock made available for trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • sales or expectations with respect to sales of shares of our common stock by holders of our common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • actual or anticipated fluctuations in our business, financial condition and results of operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • variance in our financial performance from, or failure to otherwise meet, projections, forecasts or estimates, including expectations of securities analysts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in our revenue;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • announcements by us or our competitors of significant business developments, acquisitions or new offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our involvement in any litigation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our sale of our common stock or other securities in the future or the perception that such sales might occur in large quantities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in senior management or key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the trading volume of our common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in the anticipated future size and growth rate of our market; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • general economic, political, regulatory and market conditions.

Historically, the stock markets have experienced extreme price and volume fluctuations from time to time that have affected and continue to affect the market prices of equity securities of many companies. In the past, companies that have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future, which could result in substantial costs and divert our management's attention.

 ***If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our common stock adversely, the trading price of our common stock and trading volume could decline.***

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not control these analysts. If any of the analysts

------

[**TABLE OF CONTENTS**](#TOC)

who cover us downgrade our common stock or our industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business, the price of our common stock may decline. If analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our common stock to decline and our common stock to be less liquid.

 ***Your percentage ownership in us may be diluted by future issuances of capital stock, which could reduce your influence over matters on which shareholders vote.***

Our Board of Directors has the authority, without action or vote of our shareholders, to issue shares of our common stock, including shares issuable upon exercise of options, or shares of our authorized but unissued preferred stock, subject to the applicable rules of the NYSE. Issuances of common stock or voting preferred stock would reduce your influence over matters on which our shareholders vote and, in the case of issuances of preferred stock, would likely result in your interest in us being subject to the prior rights of holders of that preferred stock.

 ***There may be sales of a substantial amount of our common stock after this offering by our current shareholders, and these sales could cause the price of our common stock to fall.***

As of April 3, 2026, there were 31,310,209 shares of our common stock outstanding. Following completion of this offering, approximately 1.2% of our outstanding common stock will be held by investment funds affiliated with American Industrial Partners. Sales of substantial amounts of our common stock in the public market after this offering, or the perception that such sales will occur, could adversely affect the market price of our common stock and make it difficult for us to raise funds through securities offerings in the future. In addition, we have registered shares of our common stock that are reserved for issuance under our 2014 Omnibus Incentive Plan, as amended.

All statements included or incorporated by reference in this prospectus supplement, 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.

New risks and uncertainties arise from time to time, and we cannot predict those events or how they may affect us. We claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 for all 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 our historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to: 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, cyber-attacks or cyber intrusions, and other disruptions to our information technology and operation; our mix of cost-plus, cost-reimbursable, firm-fixed-price and time-and-materials 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, including potential changes or uncertainty arising from the U.S. president and administration; government regulations and compliance therewith, including changes to the Department of War procurement process; changes in technology; our ability to protect our intellectual property rights; 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 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 agreements; inflation and interest rate risk; geopolitical risk, including as a result of recent global hostilities and tariffs; our suppliers' 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 and unions; 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 integrating and refining internal control systems, including enterprise resource planning and business systems; changes in generally accepted accounting principles; and other factors described in Part I, Item 1A, "Risk Factors" and elsewhere in the Annual Report on Form 10-K and Part II, "Item 1A. Risk Factors" of the Quarterly Report on Form 10-Q for the quarterly period ended April 3, 2026, and described from time to time in our future reports filed with the SEC.

In addition, statements that contain "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this prospectus supplement. While we believe that this information provides a reasonable basis for these statements, this information may be limited or incomplete.

These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

#### USE OF PROCEEDS
We will not receive any proceeds from the sale of shares of our common stock in this offering by the selling shareholder. The selling shareholder will receive all of the net proceeds from the sale of its shares of our common stock. See "Selling Shareholder."

[**TABLE OF CONTENTS**](#TOC)

#### SELLING SHAREHOLDER
The following table sets forth information as of April 3, 2026 with respect to the beneficial ownership of our common stock by the selling shareholder. The amounts and percentages of shares beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a "beneficial owner" of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days of the determination date. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person's ownership percentage, but not for purposes of computing any other person's percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Applicable percentage of beneficial ownership before this offering is based on 31,310,209 shares of common stock issued and outstanding as of April 3, 2026. Applicable percentage of beneficial ownership after this offering reflects the sale of 2,004,569 shares of common stock by the selling shareholder.

We have determined beneficial ownership in accordance with the rules of the SEC. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that each person or entity named in the table below has sole voting and investment power with respect to all shares of common stock that he, she or it beneficially owns, subject to applicable community property laws.

#### U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF COMMON STOCK
The following is a discussion of U.S. federal income tax considerations generally applicable to the ownership and disposition of our common stock by Non-U.S. Holders (defined below). This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations promulgated thereunder, rulings and official pronouncements of the Internal Revenue Service ("IRS"), and judicial decisions, all as in effect on the date of this prospectus supplement and all of which are subject to change and differing interpretations, possibly with retroactive effect. This discussion addresses tax considerations only for holders that purchase our common stock pursuant to this offering and that hold such stock as a "capital asset" as defined in the Code (generally, property held for investment). Moreover, this discussion is for general information only and does not address all of the tax consequences that may be relevant to specific investors in light of their particular circumstances or to investors subject to special treatment under U.S. federal income tax laws (such as banks, insurance companies, regulated investment companies, real estate investment trusts, tax-exempt entities, dealers in securities, traders in securities that elect to use a mark to market method of accounting or persons subject to special tax accounting rules as a result of any item of gross income with respect to our common stock being taken into account in an "applicable financial statement," brokers, expatriates, entities or arrangements treated as partnerships or other pass-through entities or arrangements for U.S. federal income tax purposes, and partners or members therein, persons that have a functional currency other than the United States dollar, controlled foreign corporations, passive foreign investment companies, persons that own, or are deemed to own, more than 5% of our outstanding common stock (except to the extent specifically set forth below), persons that hold our common stock as part of a straddle, hedge, conversion transaction or other integrated investment, persons subject to the alternative minimum tax or persons deemed to sell our common stock under the constructive sale provisions of the Code), all of whom may be subject to tax rules that differ significantly from those summarized below. The discussion below does not address U.S. federal estate and gift tax considerations, the Medicare tax or the effect of any state, local or non-U.S. tax law.

 **PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, INCLUDING THE APPLICABILITY OF U.S. FEDERAL, STATE OR LOCAL TAX LAWS, NON-U.S. TAX LAWS OR INCOME TAX TREATIES.** 

For purposes of this discussion, a "Non-U.S. Holder" is a beneficial owner of our common stock, other than an entity treated as a partnership for U.S. federal income tax purposes, that is not a U.S. Holder.

A "U.S. Holder" is a beneficial owner of our common stock that, for U.S. federal income tax purposes, is or is treated as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a citizen or individual resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a corporation created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a trust (1) if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions, or (2) that has in effect a valid election to be treated as a United States person for U.S. federal income tax purposes.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A partnership holding our common stock and each of its partners should consult their own tax advisors as to the tax consequences of holding and disposing of our common stock.

#### Distributions on Our Common Stock
Distributions (if any) on our common stock will constitute dividends for U.S. federal income tax purposes to the extent of the Company's current or accumulated earnings and profits as determined under

------

[**TABLE OF CONTENTS**](#TOC)

the Code. Dividends received by a Non-U.S. Holder with respect to our common stock will generally be subject to U.S. withholding tax at a rate of 30% (or lower treaty rate if applicable) unless such dividends are effectively connected with a Non-U.S. Holder's conduct of a trade or business within the United States (and, if an applicable income tax treaty so requires, are attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States) or the Non-U.S. Holder provides proper certification of its eligibility for a reduced rate under an applicable income tax treaty (generally on IRS Form W-8BEN or W-8BEN-E). Distributions that exceed the Company's current or accumulated earnings and profits will reduce the Non-U.S. Holder's basis in its common stock (but not below zero). Any excess will be treated as gain realized on the sale or other taxable disposition of our common stock and will be treated as described under "— *Sale or Other Disposition of Our Common Stock*" below.

Non-U.S. Holders should expect that the gross amount of any distributions with respect to our common stock will generally be subject to U.S. withholding tax unless the applicable withholding agent elects to withhold a lesser amount based on a reasonable estimate of the amount of the distribution that would be treated as a dividend.

Dividends that are effectively connected with a Non-U.S. Holder's conduct of a trade or business within the United States (and, if an applicable income tax treaty so requires, are attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States) will generally not be subject to U.S. withholding tax if the Non-U.S. Holder complies with applicable certification and disclosure requirements (generally by providing an IRS Form W-8ECI). Instead, such dividends will generally be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal income tax rates generally applicable to U.S. Holders and, in the case of corporate Non-U.S. Holders, may also be subject to a branch profits tax at a rate of 30%.

#### Sale or Other Disposition of Our Common Stock
A Non-U.S. Holder will generally not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business in the United States (and if an applicable income tax treaty so requires, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States), in which case the gain will generally be subject to U.S. federal income tax on a net income basis at the regular graduated rates generally applicable to U.S. Holders and, in the case of corporate Non-U.S. Holders, may also be subject to branch profits tax at a rate of 30% (or lower treaty rate if applicable);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition, and certain other requirements are met, in which case the gain, which may be offset by U.S. source capital losses in certain circumstances, will generally be subject to U.S. federal income tax at a rate of 30%; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the Company is, or at any point during the shorter of the five-year period ending on the date of disposition and the Non-U.S. Holder's holding period has been, a United States real property holding corporation ("USRPHC") for U.S. federal income tax purposes and, if our common stock is "regularly traded on an established securities market," the Non-U.S. Holder held, directly or indirectly, at any time during such period, more than 5% of the issued and outstanding common stock, in which case the gain will generally be subject to tax on a net income basis as gain that is effectively connected with the Non-U.S. Holder's conduct of a trade or business in the United States as described in the first bullet above.

The Company believes it is not and has not been a USRPHC at any point during the past five years, and it does not anticipate that it will become a USRPHC in the foreseeable future.

#### Information Reporting and Backup Withholding
We must report annually to the IRS and to each Non-U.S. Holder the gross amount of the distributions on our common stock paid to such holder and the tax withheld, if any, with respect to such distributions.

------

[**TABLE OF CONTENTS**](#TOC)

A Non-U.S. Holder generally will be subject to backup withholding (currently at a rate of 24%) on dividends paid with respect to such Non-U.S. Holder's shares of our common stock unless such holder certifies under penalties of perjury that, among other things, it is a Non-U.S. Holder (and the payor does not have actual knowledge, or reason to know, that such holder is a United States person (as defined in the Code)) or otherwise establishes an exemption.

Information reporting and backup withholding generally will apply to the proceeds of a disposition of our common stock by a Non-U.S. Holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder certifies its status as a Non-U.S. Holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a Non-U.S. Holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker.

Copies of information returns may be made available to the tax authorities of the country in which the Non-U.S. Holder resides or is incorporated under the provisions of a specific treaty or agreement.

Backup withholding is not an additional tax. Rather, any amounts withheld under the backup withholding rules from a payment to a Non-U.S. Holder can be refunded or credited against the Non-U.S. Holder's U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS. Non-U.S. Holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

#### Foreign Account Tax Compliance Act
Under the Foreign Account Tax Compliance Act and the regulations and administrative guidance promulgated thereunder ("FATCA"), withholding at a rate of 30% will generally be required on payments of dividends in respect of our common stock held by or through certain foreign financial institutions (including investment funds), unless such institution otherwise qualifies for an exemption or (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (ii) if required under an intergovernmental agreement between the U.S. and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country, or other guidance, may modify these requirements. Similarly, in certain circumstances, dividends in respect of our common stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will generally be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have any "substantial United States owners" or (ii) provides certain information regarding the entity's "substantial United States owners," which we will in turn provide to the IRS. Accordingly, the entity through which an investor holds our common stock will affect the determination of whether withholding under the rules described in this paragraph is required. Prospective investors should consult their own tax advisors regarding the possible implications of these rules on an investment in our common stock.

#### No Sales of Similar Securities
We have agreed that for a period of 30 days after the date of this prospectus supplement (the "Lock-Up Period"), we will not, without the prior written consent of the underwriter, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by us or any of our affiliates or any person in privity with us or any of our affiliates), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the SEC in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other shares of common stock or any securities convertible into, or exercisable for, shares of common stock (the "Lock-Up Securities"); or publicly announce an intention to effect any such transaction, provided, however, that we may issue and sell shares of common stock pursuant to any of our employee stock option plan, stock ownership plan or dividend reinvestment plan in effect on the date of this prospectus supplement and we may issue shares of common stock issuable upon the conversion of securities or the exercise of warrants outstanding on the date of this prospectus supplement.

#### Stabilization and Short Positions
Until the distribution of the shares is completed, SEC rules may limit the underwriter from bidding for and purchasing our common stock. However, the underwriter may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

------

[**TABLE OF CONTENTS**](#TOC)

Similar to other purchase transactions, the underwriter's purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriter may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.

None of us, the selling shareholder or the underwriter makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, none of us, the selling shareholder or the underwriter makes any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

A prospectus in electronic format is being made available on an Internet web site maintained by the underwriter. Other than the prospectus in electronic format, the information on the underwriter's web site and any information contained in any other web site maintained by the underwriter is not part of the prospectus or the registration statement of which the prospectus forms a part.

#### Listing

#### ABOUT THIS PROSPECTUS
This prospectus is part of a registration statement on Form S-3 that we filed with the SEC, utilizing a "shelf" registration process. Under this process, selling shareholders named in this prospectus or in one or more supplements to this prospectus may sell shares of our common stock from time to time. Each time any selling shareholder not named herein sells shares of our common stock under the registration statement of which this prospectus is a part, such selling shareholder will provide a copy of this prospectus and any applicable prospectus supplement, as required by law. Any applicable prospectus supplement may add, update, or change information contained in this prospectus.

The selling shareholders may offer and sell shares of our common stock directly to purchasers, through agents selected by the selling shareholders, or to or through underwriters or dealers. A prospectus supplement, if required, may describe the terms of the plan of distribution and set forth the names of any agents, underwriters, or dealers involved in the sale of shares of our common stock. See "Plan of Distribution."

You should read this prospectus together with any applicable prospectus supplement, as well as additional information described under the heading "Where To Find Additional Information." You should rely only on the information contained or incorporated by reference in this prospectus, any accompanying prospectus supplement and any applicable "free writing prospectus" prepared by us or on our behalf. We have not authorized, and no selling shareholder has authorized, anyone else to provide you with different or additional information. No offer of shares of our common stock is being made in any jurisdiction where the offer or sale is not permitted.

The information in this prospectus, any accompanying prospectus supplement, and the documents incorporated by reference herein and therein is accurate only as of their respective dates or as of any earlier date as of which such information is given, even though this prospectus may be delivered, or our common stock may be sold under this prospectus, on a later date. Our business, financial condition, results of operations, and prospects may have changed since those dates. You should carefully read the entire prospectus, as well as the documents incorporated by reference in the prospectus, any applicable prospectus supplement and any applicable "free writing prospectus" prepared by us or on our behalf before making an investment decision.

#### The Offering
Our common stock offered by the selling shareholders

18,591,866 shares

Our common stock is listed on the NYSE under the symbol

VVX

Use of proceeds

All of the shares of our common stock being offered under this prospectus are being sold by the selling shareholders. Accordingly, we will not receive any proceeds from the sale of these shares.

#### Background
On March 7, 2022, we entered into the merger agreement. Pursuant to the merger agreement, on July 5, 2022, Andor Inc. merged (the "first merger") with and into Vertex, with Vertex surviving the first merger as a direct, wholly owned subsidiary of V2X, and immediately following the first merger, Vertex merged (the "second merger," and together with the first merger, the "mergers") with and into Andor LLC, with Andor LLC surviving the second merger as a direct, wholly owned subsidiary of V2X. Upon the completion of the mergers, 18,591,866 shares of our common stock were issued to the selling shareholders.

On December 6, 2021, Vertex Aerospace LLC, an indirect, wholly owned subsidiary of Vertex, acquired Raytheon Technologies Corporation's Mission Critical Solutions and Training Services Business (the "TTS business") pursuant to the Share and Asset Purchase and Sale Agreement, dated as of September 8, 2021, by and among Vertex, Vertex Aerospace LLC and Raytheon Technologies Corporation. The TTS business was comprised of Raytheon Professional Services and certain assets within the Raytheon Intelligence and Space portfolio.

#### RISK FACTORS
Investing in our common stock involves risk. Prior to making a decision about investing in our common stock, you should carefully consider the specific factors discussed below and under the heading "Risk Factors" in any prospectus supplement, together with all of the other information contained or incorporated by reference in this prospectus or any prospectus supplement. You should also consider the risk factors related to our business and operations described in Part I, Item 1A, "Risk Factors" of our [Annual Report on Form 10-K for the fiscal year ended December 31, 2021](https://www.sec.gov/ix?doc=/Archives/edgar/data/1601548/000160154822000018/vec-20211231.htm), Part II, Item 1A, "Risk Factors" of our [Quarterly Report on Form 10-Q for the fiscal quarter ended July 1, 2022](https://www.sec.gov/ix?doc=/Archives/edgar/data/1601548/000160154822000088/vec-20220701.htm), and under the captions "Risks Relating to the Combined Company Following the Mergers" and "Risks Relating to Vertex's Business and Operations" beginning on pages 29 and 39, respectively, of our [Definitive Proxy Statement on Schedule 14A, filed with the SEC on May 9, 2022](https://www.sec.gov/Archives/edgar/data/1601548/000110465922057271/tm2210280-3_defm14a.htm), which are incorporated by reference herein. See "Where To Find Additional Information" in this prospectus. The risks and uncertainties we have described therein and below are not the only risks that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

 ***If the selling shareholders immediately sell their shares of our common stock received in the mergers after such shares are no longer subject to resale restrictions our common stock price could decline.***

The issuance of our common stock in connection with the mergers could have the effect of depressing the market price for our common stock, through dilution of earnings per share or otherwise. Once the registration statement, of which this prospectus is a part, is declared effective, all of the shares of our common stock issued to the selling shareholders in connection with the completion of the mergers will be available for resale in the public market, subject to restrictions on sales contained in the shareholders agreement, dated as of July 5, 2022, among the company and the selling shareholders (the "shareholders agreement"). As of the date of this prospectus, approximately 61.07% of the outstanding shares of our common stock are held by the selling shareholders.

In addition, the selling shareholders may decide not to hold the shares of our common stock they received upon completion of the mergers. Other selling shareholders, such as funds with limitations on their permitted holdings of stock in individual issuers, may be required to sell the shares of our common stock that they received upon completion of the mergers. Such sales of our common stock could have the effect of depressing the market price for our common stock and may take place promptly following the effectiveness of the registration statement, of which this prospectus is a part. In addition, future events and conditions could increase the dilution that is currently projected, including adverse changes in market conditions, additional transaction and integration related costs and other factors such as the failure to realize some or all of the benefits anticipated in the mergers. Any dilution of, or delay of any accretion to, our earnings per share could cause the price of shares of our common stock to decline or grow at a reduced rate. These sales may also make it more difficult for us to sell equity or equity-linked securities in the future at a time and at a price that we deem appropriate to raise funds through future offerings.

This prospectus and the documents incorporated by reference herein contain, and any prospectus supplement and the documents incorporated therein may contain, 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.

New risks and uncertainties arise from time to time, and we cannot predict those events or how they may affect us. We claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 for all 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.

At the closing of the mergers, the company also entered into the shareholders agreement, which among other things, (1) provides Vertex Aerospace Holdco LLC ("Vertex Holdco") and its affiliates to which shares of our common stock are transferred by a selling shareholder (the "Vertex Holdco Parties") with director nomination and committee designation rights, (2) governs how each selling shareholder will vote its shares of our common stock with respect to certain matters, (3) requires certain actions of the company to be approved by the Vertex Holdco Parties, (4) provides the Vertex Holdco Parties with certain information rights, (5) limits transfers of our common stock by the selling shareholders, (6) limits certain acquisitions of our common stock by the Vertex Holdco Parties, (7) restricts the ability of the Vertex Holdco Parties to solicit proxies in the election of directors for such periods indicated therein, and (8) provides that the company will elect to be a "controlled company" for purposes of applicable listing standards for so long as it qualifies to do so.

In accordance with the terms of the merger agreement, effective as of the closing of the mergers, the company's board of directors became comprised of eleven members, five of whom were appointed by Vertex Holdco (John "Ed" Boyington, Jr., Dino M. Cusumano, Lee E. Evangelakos, Joel M. Rotroff and Neil Snyder).

Beneficial ownership is determined in accordance with the rules of the SEC, and includes voting or investment power with respect to our common stock. To our knowledge, the selling shareholders have sole voting and investment power with respect to their respective shares of our common stock, unless otherwise noted below. The selling shareholders may sell some, all or none of their respective shares of our common stock offered by this prospectus from time to time. We do not know how long the selling shareholders will hold their respective shares of our common stock covered hereby before selling them. Other than the merger agreement, including the registration rights agreement and the shareholders agreement, we currently have no agreements, arrangements or understandings with the selling shareholders regarding the sale of any of the shares of our common stock being offered hereunder. As of the date of this prospectus, Vertex Holdco owns a majority of the outstanding shares of our common stock.

#### PLAN OF DISTRIBUTION
We are registering the offer and sale, from time to time, by the selling shareholders of up to 18,591,866 shares of our common stock, par value $0.01 per share. We will not receive any of the proceeds from the sale of our common stock by the selling shareholders.

Once issued and upon effectiveness of the registration statement of which this prospectus forms a part, our common stock beneficially owned by the selling shareholders covered by this prospectus may be offered and sold from time to time by the selling shareholders. The term "selling shareholders" includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from a selling shareholder as a gift, pledge, partnership distribution or other transfer. The selling shareholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. Each selling shareholder reserves the right to accept and, together with its respective agents, to reject, any proposed purchase of securities to be made directly or through agents. The selling shareholders and any of their permitted transferees may sell their securities offered by this prospectus on any stock exchange, market or trading facility on which our common stock is traded or in private transactions.

Subject to any limitations set forth in the registration rights agreement, the selling shareholders may use any one or more of the following methods when selling our common stock offered by this prospectus:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ordinary brokerage transactions and transactions in which the broker solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • block trades in which the broker-dealer so engaged will attempt to sell our common stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an over-the-counter distribution in accordance with the rules of the applicable exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • settlement of short sales entered into after the date of this prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • agreements with broker-dealers to sell a specified number of our common stock at a stipulated price per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in "at the market" offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • directly to purchasers, including through a specific bidding, auction or other process or in privately negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through a combination of any of the above methods of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any other method permitted pursuant to applicable law.

In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.

In effecting sales, broker-dealers or agents engaged by the selling shareholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling shareholders in amounts to be negotiated immediately prior to the sale.

The selling shareholders also may transfer our common stock in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this

[**TABLE OF CONTENTS**](#TOC3)

prospectus. Upon being notified by a selling shareholder that a donee, pledgee, transferee or other successor- in-interest intends to sell our common stock, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a selling shareholder.

To the extent required, the shares of our common stock to be sold, the names of the selling shareholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In connection with the sale of shares of our common stock, the selling shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares of our common stock in the course of hedging the positions they assume. The selling shareholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge our common stock to broker-dealers that in turn may sell these shares. The selling shareholders may also enter into options or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In offering our common stock covered by this prospectus, the selling shareholders and any underwriters, broker-dealers or agents who execute sales for the selling shareholders may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. Any discounts, commissions, concessions or profit they earn on any resale of those securities may be underwriting discounts and commissions under the Securities Act.

In order to comply with the securities laws of certain states, if applicable, our common stock must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states shares of our common stock may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We have advised the selling shareholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling shareholders and their affiliates. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling shareholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling shareholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.
