THE COMPANY

We are a space infrastructure and services company founded in 2013 and focused on enabling sustained infrastructure and human activity beyond Earth. We believe the United States is transitioning from episodic space missions to long-duration operations and persistent presence, and we are building the systems and services required to support this evolution across civil, national security, and commercial markets.

We build spacecraft, connect space-based networks, and operate infrastructure as-a-service that support operations across low Earth orbit ("LEO"), geostationary orbit ("GEO"), cislunar space, and deep-space. Our strategy is to evolve space activity from single-mission execution toward continuously operating infrastructure by combining spacecraft delivery with network connectivity and long-term operations. We believe this approach positions us to support enduring government requirements while enabling the development of a commercial space economy.

For a description of our business, financial condition, results of operations and other important information regarding the Company, we refer you to our filings with the SEC incorporated by reference in this prospectus. See "Where You Can Find More Information" and "Incorporation by Reference."

SELLING STOCKHOLDERS

This prospectus relates to the resale from time to time of an aggregate of 34,565,097 shares of our Class A Common Stock. The selling stockholders may from time to time offer and sell any or all of the securities set forth below pursuant to this prospectus and any accompanying prospectus supplement. When we refer to the "selling stockholders" in this prospectus, we mean the persons listed in the table below, and the pledgees, donees, transferees, assignees, successors, designees, and other permitted transferees who later come to hold any of the selling stockholders interest in the securities other than through a public sale.

The following table sets forth, to our knowledge, certain information about the selling stockholders as of April 1, 2026. The information in the table below with respect to the selling stockholders has been obtained from the selling stockholders based on written representations. Each selling stockholder identified below may have sold, transferred or otherwise disposed of all or a portion of its securities after the date on which it provided us with information regarding its securities or acquired additional securities. To the extent required, any changed or new information given to us by the selling stockholders, including regarding the identity of, and the securities available for sale by, the selling stockholders, may be set forth in a prospectus supplement, amendments to the registration statement of which this prospectus is a part or in filings we make with the SEC under the Exchange Act, which are incorporated by reference. For information on the methods of sale that may be used by the selling stockholders, please see "Plan of Distribution."

The percentage of beneficial ownership information below is based upon 159,372,567 shares of Class A Common Stock issued and outstanding as of March 11, 2026 and excludes any shares of Class A Common Stock that may be received upon conversion, exchange or exercise of other outstanding securities such as the our Series A Preferred Stock, Preferred Investor Warrants, Conversion Series A Warrants or OpCo Common Units.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days. Unless otherwise indicated below, to our knowledge, the persons and entities named in the tables have sole voting and sole investment power with respect to all securities that they beneficially own, subject to community property laws where applicable. Beneficial ownership percentages presented below do not reflect voting power because the calculation is limited to outstanding shares of Class A Common Stock. Holders of shares of Class A Common Stock, Class B Common Stock and Class C Common Stock will vote together as a single class on all matters submitted to the stockholders for their vote or approval. Holders of Class A Common Stock and Class B Common Stock are entitled to one vote per share on all matters submitted to the stockholders for their vote or approval and holders of Class C Common Stock are entitled to three votes per share on all matters submitted to the stockholders for their vote or approval. Additionally, holders of our Series A Preferred Stock receive one vote on an as converted Class A Common Stock basis and generally vote as a single class with holders of our common stock. As of March 11, 2026, no shares of Class B Common Stock were outstanding, 57,428,185 shares of Class C Common Stock were outstanding and 5,000 shares of Series A Preferred Stock were outstanding.

We cannot advise you as to whether the selling stockholders will sell any or all shares of Class A Common Stock. To the extent a selling stockholder sells shares of Class A Common Stock, such shares would not be available for sale pursuant to this prospectus. For purposes of this table, we have assumed that the selling

8

stockholders will have sold all of the securities covered by this prospectus upon the completion of the resale offering and no other purchase or sales of our securities by the selling stockholders will have occurred.

Certain provisions of the Certificate of Incorporation and Bylaws may be deemed to have an anti-takeover effect and may delay or prevent a tender offer or takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares of Common Stock.

Common Stock

Rights upon liquidation.In the event of liquidation, dissolution or winding up of the affairs of Intuitive Machines, whether voluntary or involuntary, after payment or provision for payment of the debts and other

12

Conversion of Class B Common Stock and Class C Common Stock

Conversion upon transfer.A holder of Class B Common Stock or Class C Common Stock may surrender shares of Class B Common Stock or Class C Common Stock to us for cancellation for no consideration at any time. Following the surrender or other acquisition of any shares of Class B Common Stock or Class C Common Stock to or by us, we will take all actions necessary to cancel and retire such shares and such shares shall not be re-issued by us.

A holder of Class B Common Stock or Class C Common Stock may transfer or assign shares of Class B Common Stock or Class C Common Stock (or any legal or beneficial interest in such shares) (directly or indirectly, including by operation of law) only to a permitted transferee of such holder or to a non-permitted transferee with our approval in advance and in writing, and only if such holder also simultaneously transfers, in each case, an equal number of such holder's OpCo Common Units to such permitted transferee or such non-permitted transferee, as applicable, in compliance with the A&R Operating Agreement.

The Board (including a majority of the directors who are disinterested with respect to the relevant transaction serving on the Board at such time) may, to the extent permitted by law, from time to time establish, modify, amend or rescind, by bylaw or otherwise, regulations and procedures not inconsistent with the provisions described herein for determining whether any transfer or acquisition of shares of Class B Common Stock or Class C Common Stock would violate the restrictions described herein and for the orderly application, administration and implementation of the provisions of the Certificate of Incorporation.

Voluntary Conversion.Each one share of Class C Common Stock shall be convertible into one share of Class B Common Stock at the option of the holder thereof at any time upon written notice to our transfer agent. Shares of Class C Common Stock that are converted into shares of Class B Common Stock as provided in the Certificate of Incorporation shall be retired and may not be reissued.

Automatic Conversion.On the earliest to occur of: (i) the date that is seven (7) years from the date of the Certificate of Incorporation and (ii) the first date on which the Permitted Class C Owners cease to own, in the aggregate, at least 33.0% of the number of shares of Class C Common Stock issued and held by the Permitted Class C Owners immediately following the closing of the Transactions (adjusted as appropriate to reflect any stock splits, reverse stock splits, stock dividends (including any dividend or distribution of securities convertible into Common Stock), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change or transaction) (such date, the "Automatic Conversion Date"), each outstanding share of Class C Common Stock shall automatically, without any further action by us or any stockholder, convert into one fully paid and nonassessable share of Class B Common Stock. Following such conversion, the reissuance of such shares of Class C Common Stock shall be prohibited, and such shares of Class C Common Stock shall be retired and cancelled in accordance with the applicable provisions of the applicable law.

Conversion to Class A Common Stock.After the expiration of the Lock-Up Period, holders of certain OpCo Common Units will be permitted to exchange such OpCo Common Units (along with the cancellation of the paired share of Class B Common Stock or share of Class C Common Stock) for shares of Class A Common Stock on a one-for-one basis pursuant to the A&R Operating Agreement (subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications) or, at our election (determined by a majority of

14

our directors who are disinterested with respect to such determination), cash from a substantially concurrent public offering or private sale in an amount equal to the net amount, on a per share basis, of cash received as a result of such public offering or private sale.

Preferred Stock

The total of our authorized shares of Preferred Stock is 25,000,000 shares. We currently have 5,000 shares of Series A Preferred Stock issued and outstanding.

The Certificate of Incorporation authorizes the Board to establish one or more series of Preferred Stock. Unless required by law or any stock exchange, the authorized shares of Preferred Stock are available for issuance without further action by the holders of Common Stock.

Our Board has the discretion to determine the powers, preferences and relative, participating, optional and other special rights, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of Preferred Stock. The issuance of Preferred Stock may have the effect of delaying, deferring or preventing a change in control of Intuitive Machines without further action by the stockholders. Additionally, the issuance of Preferred Stock may adversely affect the holders of our Common Stock by restricting dividends on the Common Stock, diluting the voting power of the Common Stock or subordinating the liquidation rights of the Common Stock. As a result of these or other factors, the issuance of Preferred Stock could have an adverse impact on the market price of our Common Stock.

Dividends:The Series A Preferred Stock pays dividends, semi-annually at the rate of 10% of the original price per share, plus the amount of previously accrued, but unpaid dividends, compounded semi-annually, and participates with our Common Stock on all other dividends. Accrued dividends may be paid (i) in cash, (ii) subject to satisfaction of certain equity conditions, in shares of Class A Common Stock or (iii) accumulated, compounded and added to the liquidation preference described below.

Liquidation Preference:Upon any liquidation or deemed liquidation event, the holders of Series A Preferred Stock will be entitled to receive out of the available proceeds, before any distribution is made to holders of common stock or any other junior securities, an amount per share equal to the greater of (i) 100% of the Accrued Value (as defined in the Certificate of Designation) or (ii) such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into Class A Common Stock immediately prior to the liquidation event.

Voting:The Series A Preferred Stock votes together with our Common Stock on an as-converted basis, except as required by law and (ii) as noted below under "Protective Provisions." Each holder of Series A Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of Class A Common Stock into which the shares of Series A Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter.

Protective Provisions:For as long as 25% of the shares of Series A Preferred Stock issued as of the Closing are outstanding, we shall not, without the affirmative vote or action by written consent of holders of more than 50% of the issued and outstanding shares of Series A Preferred Stock (the "Requisite Holders"), take any of the following actions: (i) liquidate, dissolve or wind up the affairs of Intuitive Machines; (ii) amend, alter, or repeal any provision of the Certificate of Incorporation, Bylaws or any similar document of Intuitive Machines in a manner adverse to the Series A Preferred Stock; (iii) create or authorize the creation of or issue any other security convertible into or exercisable for any equity security unless such security ranks junior to the Series A Preferred Stock with respect to its rights, preferences and privileges, or increase the authorized number of shares of Series A Preferred Stock; provided, that Intuitive Machines shall be permitted to issue up to $50.0 million in equity securities without the consent of the Requisite Holders; (iv) purchase or redeem or pay any cash dividend on any capital stock prior to the Series A Preferred Stock, other than stock repurchased at cost from former

15

employees and consultants in connection with the cessation of their service; or (v) incur or guarantee any indebtedness, if the aggregate indebtedness of Intuitive Machines and its subsidiaries for borrowed money following such action would exceed $100,000,000; provided, however, that the Series A Preferred Stock shall not be considered indebtedness for purposes of this calculation (irrespective of the accounting treatment that the Series A Preferred Stock receives under Intuitive Machines' financial statements).

Conversion:Each share of Series A Preferred Stock will be convertible at the holder's option into shares of Class A Common Stock at an initial conversion ratio determined by dividing the Accrued Value (as defined in the Certificate of Designation) of such shares of Series A Preferred Stock by the conversion price of $12.00 per share subject to adjustment in accordance with the terms of the Certificate of Designation.

Put Rights:Unless prohibited by applicable law governing distributions to stockholders, the Series A Preferred Stock shall be redeemable at the option of the Requisite Holders commencing any time after the 5th year anniversary of the Closing at a price equal to the 100% of the sum of (i) original purchase price plus (ii) all accrued/declared but unpaid dividends.

Call Rights:Unless prohibited by applicable law governing distributions to stockholders, the Series A Preferred Stock shall be redeemable at our option commencing any time (A) after the 3rd year anniversary of the Closing at a price equal to the 115% of the Accrued Value, (B) after the 4th anniversary of the Closing at a price equal to the 110% of the Accrued Value and (C) after the 5th anniversary of the Closing at a price equal to the 100% of the Accrued Value.

Preferred Investor Warrants

The Preferred Investor Warrants were immediately exercisable upon issuance at the consummation of the Transactions and expire on February 13, 2028 at 5:00 p.m., New York City time (the "PIW Termination Date"). The Preferred Investor Warrants include customary cash and cashless exercise provisions. Each Preferred Investor Warrant is initially exercisable at $15.00 per share of Class A Common Stock, subject to certain adjustments including those resulting from (i) stock dividends and splits, (ii) subsequent rights offerings, (iii) pro-rata distributions, (iv) fundamental transactions, (v) certain voluntary adjustments and (vi) issuances or deemed issuances of shares of Class A Common Stock at a price below the exercise price then in effect, subject in the case of adjustments described in this clause (vi), to an exercise price floor of $11.50, in each case, in accordance with the terms of the Preferred Investor Warrants.

The Preferred Investor Warrants do not include any redemption features. The Preferred Investor Warrants may be exercised on a cashless basis if, at any time after the six-month anniversary of the Closing Date, there is not an effective registration statement with respect to the shares of Class A Common Stock issuable upon the exercise of the Preferred Investor Warrants. On the PIW Termination Date, the Preferred Investor Warrants will be automatically exercised on a cashless basis. To exercise on a cashless basis, the holder of the Preferred Investor Warrant would pay the exercise price by surrendering the Preferred Investor Warrant (or part thereof) for that number of shares of Class A Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A Common Stock underlying the Preferred Investor Warrant, multiplied by the excess of the daily volume weighted average price of the Class A Common Stock on the date specified by the Preferred Investor Warrant less the exercise price of such Preferred Investor Warrant by (y) the daily volume weighted average price of the Class A Common Stock on the date specified by the Preferred Investor Warrant.

The holders of Preferred Investor Warrants do not have the rights or privileges of holders of shares of Class A Common Stock or any voting rights in respect of the Preferred Investor Warrants or underlying shares of Class A Common Stock until they exercise their Preferred Investor Warrants and receive shares of Class A Common Stock. After the issuance of shares of Class A Common Stock upon exercise of the Preferred Investor Warrants, each holder will be entitled to one vote for each share of Class A Common Stock held of record on all matters to be voted on by stockholders.

The Conversion Series A Warrant does not include any redemption features and have a 5 years term. On the Conversion Series A Warrant Termination Date, the Conversion Series A Warrant will be automatically exercised on a cashless basis. To exercise on a cashless basis, the holder of the Conversion Series A Warrant would pay the exercise price by surrendering the Conversion Series A Warrant (or part thereof) for that number of shares of Class A Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A Common Stock underlying the Conversion Series A Warrant, multiplied by the excess of the daily volume weighted average price of the Class A Common Stock on the date specified by the Conversion Series A Warrant less the exercise price of such Conversion Series A Warrant by (y) the daily volume weighted average price of the Class A Common Stock on the date specified by the Conversion Series A Warrant.

The holder of the Conversion Series A Warrant does not have the rights or privileges of holders of shares of Class A Common Stock or any voting rights in respect of the Conversion Series A Warrant or underlying shares of Class A Common Stock until it exercises the Conversion Series A Warrant and receives shares of Class A Common Stock. After the issuance of shares of Class A Common Stock upon exercise of the Conversion Series A Warrant, the holder will be entitled to one vote for each share of Class A Common Stock held of record on all matters to be voted on by stockholders.

Anti-Takeover Effects of the Certificate of Incorporation, the Bylaws and Certain Provisions of Delaware Law

The provisions of the Certificate of Incorporation, the Bylaws and the DGCL summarized below may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that you might consider in your best interest, including an attempt that might result in your receipt of a premium over the market price for your shares of Class A Common Stock.

The Certificate of Incorporation and Bylaws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the Board and that may have the effect of delaying, deferring or preventing a future takeover or change in control of us unless such takeover or change in control is approved by such board of directors.

These provisions include:

17

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors' fiduciary duties, subject to certain

18

exceptions. The Certificate of Incorporation includes a provision that eliminates the personal liability of directors for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate our rights and our stockholders, through stockholders' derivative suits on our behalf, to recover monetary damages from a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior. However, exculpation does not apply to any director if the director has acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived an improper benefit from his or her actions as a director.

The Bylaws provide that we must indemnify and advance expenses to directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to carry directors' and officers' liability insurance providing indemnification for directors, officers and certain employees for some liabilities. We believe that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability, indemnification and advancement provisions in the Certificate of Incorporation and the Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, liability insurance and any indemnity agreements that may be entered into are necessary to attract and retain talented and experienced directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

There is currently no pending material litigation or proceeding involving our respective directors, officers or employees for which indemnification is sought.

Dissenters' Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders have appraisal rights in connection with a merger or consolidation of Intuitive Machines. Pursuant to Section 262 of the DGCL, stockholders who properly demand and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Court of Chancery of the State of Delaware (the "Delaware Court of Chancery").

Stockholders' Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action; provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder's stock thereafter devolved by operation of law.

Forum Selection

Our Certificate of Incorporation provides that unless we consent in writing to the selection of an alternative forum, the Delaware Court of Chancery is, to the fullest extent permitted by applicable law, the sole and exclusive forum for: (i) any derivative action brought by a stockholder on behalf of the Company, (ii) any claim

19

of breach of a fiduciary duty owed by any of our directors, officers, stockholders or employees, (iii) any claim against us arising under our Certificate of Incorporation, Bylaws or the DGCL or (iv) any claim against us governed by the internal affairs doctrine. Our Certificate of Incorporation designates the federal district courts of the United States as the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

Transfer Agent and Registrar

The Transfer Agent and registrar for our shares of Class A Common Stock is Continental Stock Transfer & Trust Company.

Trading Symbol and Market

Our Class A Common Stock is listed on Nasdaq under the symbol "LUNR."

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES FOR HOLDERS

OF CLASS A COMMON STOCK

The following discussion is a summary of the material U.S. federal income tax consequences to U.S. Holders and Non-U.S. Holders (each as defined below) relating to the purchase, ownership, and disposition of our Class A Common Stock but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local, or non-U.S. tax laws are not discussed. This discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the Internal Revenue Service ("IRS"), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a holder of our Class A Common Stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership, and disposition of our Class A Common Stock.

This discussion is limited to holders who hold our Class A Common Stock as a "capital asset" within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a holder's particular circumstances, including the impact of the Medicare contribution tax on net investment income and the alternative minimum tax. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

If an entity (or other arrangement) treated as a partnership for U.S. federal income tax purposes holds our Class A Common Stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. Accordingly, partnerships holding our Class A Common Stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

21

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

U.S. Holders

For purposes of this discussion, a "U.S. Holder" is any beneficial owner of our Class A Common Stock that is for U.S. federal income tax purposes:

Taxation of Distributions.

If we make distributions, the gross amount of distributions made with respect to the Class A Common Stock generally will be includible in a U.S. Holder's gross income, in accordance with such U.S. Holder's method of accounting for U.S. federal income tax purposes, as dividend income, but only to the extent that such distributions are paid out of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. The dividends will be taxable to a corporate U.S. Holder at regular corporate tax rates and will generally be eligible for the dividends received deduction if the requisite holding period is satisfied. Distributions in excess of such earnings and profits generally will be applied against and reduce the U.S. Holder's basis in its Class A Common Stock (but not below zero), and to the extent in excess of such basis, will be treated as gain from the sale or exchange of such Class A Common Stock, as described under "- Gain or Loss on Sale, Taxable Exchange, or Other Taxable Disposition of Our Class A Common Stock" below.

With respect to non-corporate U.S. Holders and with certain exceptions, dividends may be "qualified dividend income," which is taxed at the lower applicable long-term capital gain rate provided that the U.S. Holder satisfies certain holding period requirements and the U.S. Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property. If the holding period requirements are not satisfied, corporate U.S. Holders may not be able to qualify for the dividends received deduction and would have taxable income equal to the entire dividend amount, and non-corporate U.S. Holders may be subject to tax on such dividends at regular ordinary income tax rates instead of the preferential rate that applies to qualified dividend income.

Gain or Loss on Sale, Taxable Exchange, or Other Taxable Disposition of Our Class A Common Stock.

Upon a sale or other taxable disposition of our Class A Common Stock, a U.S. Holder generally will recognize capital gain or loss. Generally, the amount of gain or loss recognized by a U.S. Holder is an amount equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such disposition and (ii) the U.S. Holder's adjusted tax basis in its Class A Common Stock so disposed of. A U.S. Holder's adjusted tax basis in its Class A Common Stock generally will equal the U.S. Holder's adjusted cost less any prior distributions treated as a return of capital.

22

Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder's holding period for the Class A Common Stock so disposed of exceeds one year. If the holding period requirements are not satisfied, any gain on a sale or taxable disposition of the Class A Common Stock would be subject to short-term capital gain treatment and would be taxed at regular ordinary income tax rates. Long-term capital gains recognized by non-corporate U.S. Holders will be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding.

Distributions with respect to our Class A Common Stock to a U.S. Holder, regardless of whether such distributions constitute dividends, and proceeds from the sale, exchange or redemption of our Class A Common Stock by a U.S. Holder generally are subject to information reporting to the IRS and possible U.S. backup withholding, unless the U.S. Holder is an exempt recipient. Backup withholding may apply to such payments if a U.S. Holder fails to furnish a correct taxpayer identification number, a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder's U.S. federal income tax liability, and such holder may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Non-U.S. Holders

For purposes of this discussion, a "Non-U.S. Holder" is any beneficial owner of our Class A Common Stock that is not a U.S. Holder.

Taxation of Distributions.

If we do make distributions of cash or property on our Class A Common Stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder's adjusted tax basis in its Class A Common Stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under "- Gain or Loss on Sale, Taxable Exchange, or Other Taxable Disposition of Class A Common Stock."

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

23

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Gain or Loss on Sale, Taxable Exchange, or other Taxable Disposition of Our Class A Common Stock.

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Class A Common Stock unless:

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on gain realized upon the sale or other taxable disposition of our Class A Common Stock, which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future.

Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding.

Payments of dividends on our Class A Common Stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any distributions on our Class A Common Stock paid to the Non-U.S. Holder, regardless of whether such distributions constitute dividends or whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Class A Common Stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person or the holder otherwise establishes an exemption. Proceeds of a disposition of our Class A Common Stock conducted

24

through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting. Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts.

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or ("FATCA")) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on (i) dividends on our Class A Common Stock, and (ii) subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of our Class A Common Stock paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain "specified United States persons" or "United States owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A Common Stock. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of our Class A Common Stock, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective purchasers should consult their tax advisors regarding the potential application of withholding under FATCA to their purchase of our securities.

THE DISCUSSION ABOVE IS A GENERAL SUMMARY. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE IMPORTANT TO YOU. EACH PROSPECTIVE PURCHASER SHOULD CONSULT ITS TAX ADVISOR ABOUT THE TAX CONSEQUENCES OF AN INVESTMENT IN OUR CLASS A COMMON STOCK BASED ON THE INVESTOR'S CIRCUMSTANCES.

25

PLAN OF DISTRIBUTION

We are registering shares of Class A Common Stock for possible sale by the selling stockholders from time to time. We will not receive any proceeds from the sale by the selling stockholders. The aggregate proceeds to the selling stockholders will be the purchase price of the securities less any discounts and commissions borne by the selling stockholders.

Pursuant to the terms of the applicable registration rights agreements, we will pay certain expenses, other than underwriting discounts and commissions, associated with the sale of Class A Common Stock by the selling stockholders pursuant to this prospectus.

The shares of Class A Common Stock beneficially owned by the selling stockholders covered by this prospectus may be offered and sold from time to time by the selling stockholders. The term "selling stockholders" includes donees, pledgees, transferees or other successors in interest that sell securities received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer. A selling stockholder that is an entity may elect to make an in-kind distribution of securities to its members, partners, or stockholders pursuant to the registration statement of which this prospectus forms a part by delivering a prospectus. To the extent that such members, partners or stockholders are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradable securities pursuant to the distribution through a registration statement.

The selling stockholders 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 stockholder 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 stockholders and any of their permitted transferees may sell their securities offered by this prospectus on any stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at a fixed price or varying prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to prevailing market prices or at negotiated prices.

The selling stockholders may sell their shares by one or more of, or a combination of, the following methods:

26

There can be no assurance that the selling stockholders will sell all or any of the securities offered by this prospectus. In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus, subject to additional restrictions due to the Company's former shell company status. The selling stockholders have the sole and absolute discretion not to accept any purchase offer or make any sale of securities if they deem the purchase price to be unsatisfactory at any particular time.

Subject to the terms of the applicable registration rights agreement, selling stockholders may transfer shares of Class A Common Stock to one or more permitted transferees and, if so transferred, such permitted transferee(s) will be the selling beneficial owner(s) for purposes of this prospectus. Upon being notified by a selling stockholder of such a transfer, we will, to the extent required, by applicable law or regulation, promptly file a supplement to this prospectus to name specifically such person as a selling stockholder. Under the applicable registration rights agreements, we have agreed to indemnify the selling stockholders party thereto against certain liabilities that they may incur in connection with the sale of the securities registered hereunder, including liabilities under the Securities Act, and to contribute to payments that the selling stockholders may be required to make with respect thereto. In addition, we and the selling stockholders may agree to indemnify any underwriter, broker-dealer, or agent against certain liabilities related to the selling of the securities, including liabilities arising under the Securities Act.

With respect to a particular offering of the securities held by the selling stockholders, to the extent required, an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is part, will be prepared and will set forth the following information:

27

In connection with distributions of the shares or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of shares of Class A Common Stock in the course of hedging transactions, and broker-dealers or other financial institutions may engage in short sales of shares of Class A Common Stock in the course of hedging the positions they assume with selling stockholders. The selling stockholders may also sell shares of Class A Common Stock short and redeliver the shares to close out such short positions. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions 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). The selling stockholders may also pledge shares to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In order to facilitate the offering of the securities, any underwriters or agents, as the case may be, involved in the offering of such securities may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. Specifically, the underwriters or agents, as the case may be, may overallot in connection with the offering, creating a short position in our securities for their own account. In addition, to cover overallotments or to stabilize the price of our securities, the underwriters or agents, as the case may be, may bid for, and purchase, such securities in the open market. Finally, in any offering of securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allotted to an underwriter or a broker-dealer for distributing such securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters or agents, as the case may be, are not required to engage in these activities, and may end any of these activities at any time.

The selling stockholders may solicit offers to purchase the securities directly from, and may sell such securities directly to, institutional investors or others. In this case, no underwriters or agents would be involved. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

It is possible that one or more underwriters may make a market in our securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for our securities. Our shares of Class A Common Stock are currently listed on The Nasdaq Stock Market LLC under "LUNR."

The selling stockholders may authorize underwriters, broker-dealers or agents to solicit offers by certain purchasers to purchase the securities at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we or the selling stockholders pay for solicitation of these contracts.

The selling stockholders may enter into derivative, sale or forward sale transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any selling stockholders or borrowed from any selling stockholders or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from any selling stockholders in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any selling stockholders may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using

28

this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

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

If at the time of any offering made under this prospectus a member of the Financial Industry Regulatory Authority ("FINRA") participating in the offering has a "conflict of interest" as defined in FINRA Rule 5121 ("Rule 5121"), that offering will be conducted in accordance with the relevant provisions of Rule 5121.

To our knowledge, there are currently no plans, arrangements or understandings between the selling stockholders and any broker-dealer or agent regarding the sale of the securities by the selling stockholders. Upon our notification by a selling stockholders that any material arrangement has been entered into with an underwriter or broker-dealer for the sale of securities through a block trade, special offering, exchange distribution, secondary distribution or a purchase by an underwriter or broker-dealer, we will file, if required by applicable law or regulation, a supplement to this prospectus pursuant to Rule 424(b) under the Securities Act disclosing certain material information relating to such underwriter or broker-dealer and such offering.

Underwriters, broker-dealers or agents may facilitate the marketing of an offering online directly or through one of their affiliates. In those cases, prospective investors may view offering terms and a prospectus online and, depending upon the particular underwriter, broker-dealer or agent, place orders online or through their financial advisors.

In offering the shares covered by this prospectus, the selling stockholders and any broker-dealers who execute sales for the selling stockholders may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales (it being understood the selling stockholders shall not be deemed to be underwriters solely as a result of their participation in an offering pursuant to this prospectus). Any discounts, commissions, concessions or profit that the selling stockholders and any broker-dealers who execute sales for the selling stockholders, if deemed to be underwriters, earn on any resale of those securities may be underwriting discounts and commissions under the Securities Act.

The underwriters, broker-dealers and agents may engage in transactions with us or the selling stockholders, may have banking, lending or other relationships with us or perform services for us or the selling stockholders, in the ordinary course of business.

In order to comply with the securities laws of certain states, if applicable, the shares must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states, the shares of Class A 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 stockholders 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 stockholders and their affiliates. In addition, we will make copies of this prospectus available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders 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.

At the time a particular offer of shares is made, if required, a prospectus supplement will be distributed that will set forth the number of shares being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following table sets forth all costs and expenses, payable by us in connection with the Class A Common Stock being registered. All amounts shown are estimates except for the SEC registration fee.

Item 15. Indemnification of Directors and Officers

Subsection (a) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or who is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful.

Subsection (b) of Section 145 empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person acted in any of the capacities set forth above, against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 145 further provides that to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the indemnification provided for by Section 145 shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person's heirs, executors and administrators. Section 145 also

II-1

empowers the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify such person against such liabilities under Section 145.

Section 102(b)(7) of the DGCL provides that a corporation's certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit.

Additionally, our Certificate of Incorporation limits the liability of our directors to the fullest extent permitted by the DGCL, and our bylaws provide that we will indemnify them to the fullest extent permitted by such law. We have entered into and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by the Board. Under the terms of such indemnification agreements, we are required to indemnify each of our directors and officers, to the fullest extent permitted by the laws of the state of Delaware if the basis of the indemnitee's involvement was by reason of the fact that the indemnitee is or was our director or officer or was serving at our request in an official capacity for another entity. We must indemnify our officers and directors against all reasonable fees, expenses, charges and other costs of any type or nature whatsoever, including any and all expenses and obligations paid or incurred in connection with investigating, defending, being a witness in, participating in (including on appeal), or preparing to defend, be a witness or participate in any completed, actual, pending or threatened action, suit, claim or proceeding, whether civil, criminal, administrative or investigative, or establishing or enforcing a right to indemnification under the indemnification agreement. The indemnification agreements also require us, if so requested, to advance all reasonable fees, expenses, charges and other costs that such director or officer incurred, provided that such person will return any such advance if it is ultimately determined that such person is not entitled to indemnification by us. Any claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.
