EXPLANATORY NOTE

On July 31, 2024 (the “Closing Date”), ARYA Sciences Acquisition Corp IV, a Cayman Islands exempted company (“ARYA”), Aja Holdco, Inc., a Delaware corporation and wholly owned subsidiary of ARYA (“ListCo”), Aja Merger Sub 1, a Cayman Islands exempted company and wholly owned subsidiary of ListCo (“ARYA Merger Sub”), Aja Merger Sub 2, Inc., a Delaware corporation and wholly owned subsidiary of ListCo (“Adagio Merger Sub”), and Adagio Medical, Inc., a Delaware corporation (“Adagio Medical”) consummated the previously announced business combination (“Business Combination”) pursuant to the terms of that certain Business Combination Agreement, dated February 13, 2024, as amended by the Consent and Amendment No. 1 to Business Combination Agreement, dated as of June 25, 2024 (the “Business Combination Agreement”), each by and among the foregoing parties. In connection with the closing of the Business Combination, among other things, (i) ARYA Merger Sub merged with and into ARYA (the “ARYA Merger”) and Adagio Merger Sub merged with and into Adagio Medical (the “Adagio Merger” and, together with the ARYA Merger, the “Mergers”), with ARYA and Adagio Medical surviving the Mergers and, after giving effect to such Mergers, each of ARYA and Adagio Medical became a wholly owned subsidiary of ListCo (the time that the ARYA Merger becomes effective being referred to as the “ARYA Merger Effective Time,” the time that the Adagio Merger becomes effective being referred to as the “Adagio Merger Effective Time,” the time after which both Mergers become effective being referred to as the “Closing”), (ii) in connection with the Closing, an amended and restated certificate of incorporation of the Company filed with the Secretary of State of the State of Delaware took effect (the “Charter”), and the board of directors of the Company (the “Board”) approved and adopted amended and restated bylaws of the Company (the “Bylaws”), and (iii) in connection with the Closing, ListCo changed its name to “Adagio Medical Holdings, Inc.” (“Adagio Holdings”).

On September 13, 2024, Adagio Medical Holdings, Inc. (the “Company”) filed a registration statement on Form S-1 (File No. 333-282126, the “Prior Registration Statement”) with the Securities and Exchange Commission (“SEC”) which initially went effective on September 19, 2024. On January 14, 2025, the Company filed a new registration statement (File No. 333-284263, the “Registration Statement”) amending the Prior Registration Statement and which contained a combined prospectus pursuant to Rule 429 under the Securities Act of 1933, as amended (the “Securities Act”). The Company then filed a Pre-Effective Amendment No. 1 (“Pre-Effective Amendment No. 1”) to the Registration Statement to update the Executive Compensation section to reflect compensation paid in the fiscal year ended December 31, 2024.

The Registration Statement related to the offer, sale or other disposition from time to time of up to 31,818,652 shares of our common stock, $0.0001 par value per share (the “Common Stock”), by the selling stockholders named in this prospectus or their permitted transferees (the “selling stockholders”), consisting of (i) 73,333 shares of Common Stock (the “Registration Delay Shares”) issued pursuant to the terms of the Convert Waivers (as defined below), (ii) up to 31,145,319 shares of Common Stock (excluding the shares of Common Stock underlying the Warrants (as defined below)) (the “Convertible Note Shares”) issuable upon the conversion of those certain 13% senior secured convertible notes, with a conversion price of $10.00 per share, subject to adjustment (the “Convertible Notes”) issuable pursuant to that certain securities purchase agreement, dated February 13, 2024, by and among us and those certain investors (the “Convert Investors”), and any assignment thereunder (the “Convertible Security Subscription Agreement”), and that certain note purchase agreement, dated February 13, 2024, by and among us, Adagio Medical, Inc., a Delaware corporation, and that certain investor party thereto, and (iii) up to 600,000 shares of Common Stock (the “Warrant Shares”) issuable upon exercise of those warrants to purchase shares of Common Stock, with an exercise price of $24.00 per share (the “Warrants”), issued pursuant to the Convertible Security Subscription Agreement.

The Company is now filing this Post-Effective Amendment No. 1 (“Post-Effective Amendment No. 1”) to the Registration Statement to convert the registration statement on Form S-1 into a registration statement on Form S-3, which contains an updated prospectus relating to the sale of securities from time to time by the selling securityholders named herein. No additional securities are being registered under this Post-Effective Amendment No. 1. All applicable registration fees were paid at the time of the initial filing of the Registration Statement

The information in this preliminary prospectus is not complete and may be changed. These securities described herein may not be sold until the registration statement filed with the U.S. Securities and Exchange Commission is declared effective. This preliminary prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

SUBJECT TO COMPLETION, DATED APRIL 1, 2026

PRELIMINARY PROSPECTUS

Up to 73,333 Shares of Common Stock
Up to 31,145,319 Shares of Common Stock Issuable Upon Conversion of Notes
Up to 600,000 Shares of Common Stock Issuable Upon Exercise of Warrants

This prospectus relates to the offer, sale or other disposition from time to time of up to 31,818,652 shares of Common Stock by the selling stockholders, consisting of (i) 73,333 shares of Common Stock issued pursuant to the terms of the Convert Waivers), (ii) up to 31,145,319 shares of Convertible Note Shares issuable upon the conversion of the Convertible Notes issuable pursuant to that certain securities purchase agreement, dated February 13, 2024, by and among us and the Convert Investors, and any assignment thereunder, and that certain note purchase agreement, dated February 13, 2024, by and among us, Adagio Medical, Inc., a Delaware corporation, and that certain investor party thereto, and (iii) up to 600,000 shares of Common Stock issuable upon exercise of those warrants to purchase shares of Common Stock, with an exercise price of $24.00 per share issued pursuant to the Convertible Security Subscription Agreement.

The selling stockholders may offer, sell or distribute all or a portion of the securities hereby registered publicly or through private transactions at prevailing market prices or at negotiated prices. We will not receive any of the proceeds from such sales of these securities, except with respect to amounts received by us upon exercise of the Warrants for cash. We believe the likelihood that warrant holders will exercise their Warrants for cash and therefore the amount of cash proceeds that we would receive, is dependent upon the trading price of our Common Stock. The market price of our Common Stock is lower than the exercise prices of the Warrants as of the date of this prospectus. The value of our Common Stock will fluctuate and may not align with the exercise price of the Warrants at any given time. If the trading price for our Common Stock is less than the exercise price of the Warrants, meaning the Warrants are “out of the money”, we believe the holders of Warrants will be unlikely to exercise these Warrants. In addition, the Warrants, may be exercised on a cashless basis, under certain circumstances described herein. To the extent such Convert Warrants are exercised on a cashless basis, we would not receive any cash from such exercise and the total amount of cash that we would receive from the exercise of the Convert Warrants will decrease. Such exercises may not bring us more liquidity but result in further dilution of our Common Stock, which could adversely affect our financial position. The Warrants may only be exercised for cash provided there is then an effective registration statement registering the shares of Common Stock issuable upon the exercise of such warrants. If there is not a then-effective registration statement, then such warrants may be exercised on a “cashless basis,” pursuant to an available exemption from registration under the Securities Act of 1933, as amended. We will bear all costs, expenses and fees in connection with the registration of these securities, including with regard to compliance with state securities or “blue sky” laws. The selling stockholders will bear all commissions and discounts, if any, attributable to their sale of shares of Common Stock. See the section titled “Plan of Distribution.”

In connection with the Business Combination, holders of 2,707,555 shares of ARYA’s Class A ordinary shares, or approximately 82%, of the issued and outstanding redeemable shares of ARYA’s Class A ordinary shares, properly exercised their right to redeem their shares (and did not withdraw their redemption) for cash at a redemption price of approximately $11.56 per share, for an aggregate redemption amount of approximately $31,312,102. This offering involves the potential sale of a significant number of shares of Common Stock issuable upon the exercise of the Warrants and upon conversion of the Convertible Notes. The sale of all the securities being offered in this prospectus, or the perception that these sales could occur, could result in a significant decline in the public trading price of our securities.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol “ADGM”. On March 31, 2026, the last reported sales price of our Common Stock was $1.15 per share.

We are an “emerging growth company” as defined under U.S. federal securities laws and, as such, have elected to comply with reduced public company reporting requirements. This prospectus complies with the requirements that apply to an issuer that is an emerging growth company.

Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described in the section titled “Risk Factors” beginning on page 6 of this prospectus, and under similar headings in any amendments or supplements to this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”) using the “shelf” registration process. Under this shelf registration process, the selling stockholders may, from time to time, sell the securities offered by them described in this prospectus. We will not receive any proceeds from the sale by such selling stockholders of the securities offered by them described in this prospectus, except with respect to amounts received by us upon the exercise of any warrants for cash.

Neither we nor the selling stockholders have authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus or any applicable prospectus supplement or any free writing prospectuses prepared by or on behalf of us or to which we have referred you. Neither we nor the selling stockholders take responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. Neither we nor the selling stockholders will make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted.

The information contained in this prospectus is accurate only as of the date of this prospectus, regardless of the time of delivery of this prospectus or any sale of our securities. Our business, financial condition, results of operations and prospects may have changed since that date.

We may also provide a prospectus supplement or post-effective amendment to the registration statement to add information to, or update or change information contained in, this prospectus. You should read both this prospectus and any applicable prospectus supplement or post-effective amendment to the registration statement together with the additional information to which we refer you in the sections of this prospectus titled “Where You Can Find More Information.”

For investors outside of the United States: Neither we nor the selling stockholders, have done anything that would permit this offering or possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus must inform themselves about, and observe any restrictions relating to, the offering of our securities and the distribution of this prospectus outside the United States.

Unless stated otherwise, references in this prospectus to “we,” “us,” “our,” or “the Company,” refer to ListCo before the consummation of the Business Combination or Adagio Holdings after the Business Combination, as the context suggests.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein and any prospectus supplement delivered with this prospectus may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve substantial risks and uncertainties. The forward-looking statements are contained principally in the sections titled “Prospectus Summary,” and “Risk Factors,” but may also be contained elsewhere in this prospectus. In some cases, you can identify forward-looking statements by terms such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “objective,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will” and “would,” or the negative of these terms or other similar expressions intended to identify statements about the future. These statements speak only as of the date such forward-looking statement is made and involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements include, without limitation, statements about:

The foregoing list of risks is not exhaustive. Other sections of this prospectus, the documents incorporated by reference herein and any prospectus supplement may include additional factors that could harm our business and financial performance. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. As a result of these factors, we cannot assure you that the forward-looking statements in this prospectus, the documents incorporated by reference herein and any prospectus supplement will prove to be accurate. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise, except as required by law.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. Although we believe that we have a reasonable basis for each forward-looking statement contained in this prospectus, the documents incorporated by reference herein and any prospectus supplement, the events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. You should refer to the “Risk Factors” section of this prospectus and in our periodic filings with the SEC for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. Our SEC filings are available publicly on the SEC’s website at www.sec.gov.

You should read this prospectus and the documents that we reference in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date the statement is made, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and such statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely upon these statements.

RISK FACTORS

Investing in our common stock involves risks. Before you make a decision to invest in our common stock, in addition to the risks and uncertainties discussed above under “Special Note Regarding Forward-Looking Statements,” you should carefully consider the specific risks incorporated by reference in this prospectus from our Annual Report on Form 10-K and any subsequent quarterly reports on Form 10-Q or current reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement and any applicable free writing prospectus before acquiring any such securities.

For more information, see “Where You Can Find More Information.” If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties incorporated by reference in this prospectus or any prospectus supplement are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

USE OF PROCEEDS

All of the shares of Common Stock offered by the selling stockholders pursuant to this prospectus will be sold by the selling stockholders for their respective accounts. We will not receive any of the proceeds from these sales.

We will receive up to an aggregate of approximately $14.4 million from the exercise of the Warrants assuming the exercise in full of all of such warrants for cash. We expect to use the net proceeds from the exercise of the Warrants for general corporate purposes. We will have broad discretion over the use of such proceeds. There is no assurance that the holders of the Warrants will elect to exercise any or all of such warrants.

The Warrants may be exercised for cash or on a cashless basis. To the extent that any such warrants are exercised on a cashless basis, we would not receive any cash from such exercise and the total amount of cash that we would receive from the exercise of the Warrants will decrease. We believe the likelihood that holder of the Warrants will exercise such warrants for cash and therefore the amount of cash proceeds that we would receive, is dependent upon the trading price of our Common Stock. If the Warrants are “out of the money,” meaning the exercise price is higher than the market price of our Common Stock, the holders of the Warrants are not likely to exercise them.

In addition, while the selling stockholders may, on average, experience a positive rate of return on their investment in the Common Stock, the public securityholders may not experience a similar rate of return on the Common Stock they purchased if there is such a decline in price and due to differences in the purchase price and the current market price. The sales of the securities by the selling stockholders, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future and at a price that we deem appropriate. See “Risk Factors” for more details.

DETERMINATION OF OFFERING PRICE

We cannot currently determine the price or prices at which shares of Common Stock may be sold by the selling stockholders under this prospectus.

SELLING STOCKHOLDERS

The shares of Common Stock being offered by the selling stockholders are (i) up to 73,333 Registration Delay Shares issued pursuant to the terms of the Convert Waivers, (ii) up to 31,145,319 Convertible Note Shares and (iii) up to 600,000 Convert Warrant Shares, in each case issued pursuant to the Securities Purchase Agreement (the “Purchase Agreement”), dated as of February 13, 2024, by and among the Company, ARYA Sciences Acquisition Corp IV, Adagio Medical, Inc. and certain selling stockholders named therein.

We are registering the shares of common stock in order to permit the selling stockholders to offer the shares for resale from time to time. Except for the ownership of the Convertible Note Shares and Convert Warrant Shares issued pursuant to the Purchase Agreement, none of the selling stockholders have had any material relationship with us within the past three years.

As used in this prospectus, the term “selling stockholders” includes the selling stockholders listed in the tables below, and their permitted pledgees, donees, transferees, assignees, successors, designees, successors-in-interest and others who later come to hold any of the selling stockholders’ interest in the shares of Common Stock in accordance with the terms of the applicable agreements governing their respective registration rights, other than through a public sale.

The table below lists the selling stockholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder) of the shares of Common Stock held by each of the selling stockholders. The second column lists the number of shares of Common Stock beneficially owned by the selling stockholders prior to this offering, based on their respective ownership of shares of Common Stock, as of February 3, 2025, assuming conversion of the Convertible Notes and exercise of the Convert Warrants held by each such selling stockholder on that date but taking account of any limitations on conversion and exercise set forth therein. The third column lists the shares of Common Stock being offered by this prospectus, assuming conversion of the Convertible Notes and exercise of the Convert Warrants by the selling stockholders and does not take in account any limitations on (i) conversion of the Convertible Notes set forth therein or (ii) exercise of the Convert Warrants set forth therein.

In accordance with the terms of a registration rights agreement with the holders of the Convertible Notes and the Convert Warrants, this prospectus generally covers the resale of the sum of (i) 200% of the maximum number Convertible Note Shares issued or issuable upon conversion of the Convertible Notes, (assuming that such Convertible Notes are convertible at the alternative conversion price, defined as the lowest of (x) $10.00 and (y) 85% of the lowest volume-weighted average price of the Common Stock during the five (5) consecutive trading day period ending and including the trading day immediately preceding the delivery or deemed delivery of the applicable notice of conversion), including payment of the interest on the Convertible Notes through April 30, 2028 and (ii) the maximum number of Convert Warrant Shares issuable upon exercise of the Convert Warrants, in each case, determined as if the outstanding Convertible Notes (including interest on the Convertible Notes through April 30, 2028) and Convert Warrants were converted or exercised (as the case may be) in full (without regard to any limitations on conversion or exercise contained therein solely for the purpose of such calculation) at an alternate conversion price or exercise price (as the case may be) calculated as of the trading day immediately preceding the date this registration statement was initially filed with the SEC. Because the conversion price and alternate conversion price of the Convertible Notes and the exercise price of the Convert Warrants may be adjusted, the number of shares that will actually be issued may be more or less than the number of shares being offered by this prospectus. The fourth column assumes the sale of all of the shares offered by the selling stockholders pursuant to this prospectus.

Under the terms of the Convertible Notes and Convert Warrants, a selling stockholder may not convert the notes or exercise the warrants to the extent (but only to the extent) such selling stockholder or any of its affiliates would beneficially own a number of shares of our Common Stock which would exceed 4.99% (the “Maximum Percentage”) of the outstanding shares of the Company. The number of shares in the second column reflects these limitations. The selling stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

PLAN OF DISTRIBUTION

We are registering the resale by the selling stockholders of up to 31,145,319 shares of Common Stock from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of Common Stock, although we will receive the exercise price of any Warrants not exercised by the selling stockholders on a cashless exercise basis. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock.

The selling stockholders may sell all or a portion of the shares of Common Stock held by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of Common Stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of Common Stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, pursuant to one or more of the following methods:

The selling stockholders may also sell shares of Common Stock under Rule 144 promulgated under the Securities Act of 1933, as amended, if available, rather than under this prospectus. In addition, the selling stockholders may transfer the shares of Common Stock by other means not described in this prospectus. If the selling stockholders effect such transactions by selling shares of Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of Common Stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of Common Stock short and deliver shares of Common Stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares.

The selling stockholders may pledge or grant a security interest in some or all of the Convertible Note shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

To the extent required by the Securities Act and the rules and regulations thereunder, the selling stockholders and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed, which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or re-allowed or paid to broker-dealers.

Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any selling stockholder will sell any or all of the shares of Common Stock registered pursuant to the registration statement, of which this prospectus forms a part.

The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the selling stockholders and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

We will pay all expenses of the registration of the shares of Common Stock pursuant to the Convert Registration Rights Agreement, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act in accordance with the applicable registration rights agreements or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the applicable related registration rights agreements or we may be entitled to contribution.

Once sold under the registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following discussion is a summary of certain material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the ownership and disposition of shares of our Common Stock that are being offered pursuant to this offering. This discussion applies only to holders that hold shares of our Common Stock as “capital assets” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (generally, property held for investment).

This discussion is not a complete analysis of all potential U.S. federal income tax consequences relating to the ownership and disposition of shares of our Common Stock. This summary is based upon current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), existing U.S. Treasury Regulations promulgated thereunder, published administrative pronouncements and rulings of the U.S. Internal Revenue Service (the “IRS”), and judicial decisions, all as in effect as of the date of this prospectus. These authorities are subject to change and differing interpretation, possibly with retroactive effect. Any change or differing interpretation could alter the tax consequences to Non-U.S. Holders described in this discussion. There can be no assurance that a court or the IRS will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling with respect to the U.S. federal income tax consequences to a Non-U.S. Holder of the ownership or disposition of our securities.

This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular holder in light of that holder’s individual circumstances, nor does it address any alternative minimum, Medicare contribution, estate or gift tax consequences, or any aspects of U.S. state, local or non-U.S. taxes or any non-income U.S. tax laws. This discussion also does not address consequences relevant to holders subject to special tax rules, such as holders: owning, or deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below), corporations that accumulate earnings to avoid U.S. federal income tax, tax-exempt organizations, governmental organizations, banks, financial institutions, investment funds, insurance companies, brokers, dealers or traders in securities, commodities, or currencies, regulated investment companies or real estate investment trusts, tax-qualified retirement plans, holders who hold or receive our securities pursuant to the exercise of employee stock options or otherwise as compensation, holders holding our securities as part of a hedge, straddle, or other risk reduction strategy, conversion transaction or other integrated investment, holders deemed to sell our securities under the constructive sale provisions of the Code, passive foreign investment companies, controlled foreign corporations, S corporations, partnerships, or other pass-through entities or arrangements for U.S. federal income tax purposes (and any holder of interests therein), certain former U.S. citizens or long-term residents, and U.S. holders.

In addition, this discussion does not address the tax treatment of partnerships (or entities or arrangements that are treated as partnerships for U.S. federal income tax purposes) or persons that hold our securities through such partnerships. If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, holds shares of our Common Stock, the U.S. federal income tax treatment of a partner in such partnership generally will depend upon the status of the partner and the activities of the partnership. Such partners and partnerships should consult their tax advisors regarding the tax consequences of the ownership and disposition of shares of our Common Stock.

THIS DISCUSSION IS ONLY A SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF SHARES OF OUR COMMON STOCK THAT ARE BEING OFFERED PURSUANT TO THIS OFFERING. EACH HOLDER IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE OWNERSHIP AND DISPOSITION OF SHARES OF OUR COMMON STOCK, INCLUDING THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE, LOCAL, AND NON-U.S. TAX LAWS.

For purposes of this discussion, a “Non-U.S. Holder” means a beneficial owner of shares of our Common Stock that is neither a “U.S. person” nor a partnership (including any entity or arrangement treated as a partnership) for U.S. federal income tax purposes. A “U.S. person” is any person who or that is for U.S. federal income tax purposes:

Taxation of Distributions

In general, any distributions we make to a Non-U.S. Holder on shares of our Common Stock, to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute dividends for U.S. federal income tax purposes and, provided such dividends are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, we will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E, as applicable). Any distribution not constituting a dividend will be treated first as reducing (but not below zero) the Non-U.S. Holder’s adjusted tax basis in its shares of our Common Stock and, to the extent such distribution exceeds the Non-U.S. Holder’s adjusted tax basis, as gain realized from the sale or other disposition of the Common Stock, which will be treated as described under “— Gain on Sale, Exchange, or Other Taxable Disposition of Common Stock” below.

Dividends we pay to a Non-U.S. Holder that are effectively connected with such Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Holder) generally will not be subject to U.S. withholding tax, provided such non-U.S. Holder complies with certain certification and disclosure requirements (generally by providing an IRS Form W-8ECI). Instead, such dividends generally will be subject to U.S. federal income tax, net of certain deductions, at the same individual or corporate rates applicable to a U.S. person. If the Non-U.S. Holder is a corporation for U.S. federal income tax purposes, dividends that are effectively connected income may also be subject to a “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty). Non-U.S. Holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Non-U.S. Holders that do not provide the required certification on a timely basis, but that qualify 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.

Gain on Sale, Exchange, or Other Taxable Disposition of Common Stock

Subject to the discussions below regarding FATCA and backup withholding, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax in respect of gain recognized on a sale, exchange, or other taxable disposition of shares of our Common Stock, unless:

Gain described in the first bullet point above will be subject to tax at generally applicable U.S. federal income tax rates as if the Non-U.S. Holder were a U.S. person. Any gains described in the first bullet point above of a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional “branch profits tax” at a 30% rate (or lower applicable treaty rate). Gain described in the second bullet point above generally will be subject to a flat 30% U.S. federal income tax, which may be offset by certain U.S.-source capital losses (even though the individual is not considered a resident of the United States), provided that the Non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

If the third bullet point above applies to a Non-U.S. Holder and applicable exceptions are not available, gain recognized by such Non-U.S. Holder on the sale, exchange, or other taxable disposition of shares of our Common Stock will be subject to tax at generally applicable U.S. federal income tax rates. In addition, a buyer may be required to withhold U.S. income tax at a rate of 15% of the amount realized upon such disposition. We will be classified as a United States real property holding corporation if the fair market value of our “United States real property interests” equals or exceeds 50% of the sum of the fair market value of our worldwide real property interests plus our other assets used or held for use in a trade or business, as determined for U.S. federal income tax purposes. We believe that we are not and do not anticipate becoming a United States real property holding corporation; however, such determination is factual in nature and subject to change so there can be no assurance in this regard. Non-U.S. Holders are urged to consult their tax advisors regarding the application of these rules.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code (commonly referred to as the “Foreign Account Tax Compliance Act” or “FATCA”) and Treasury Regulations and administrative guidance promulgated thereunder impose a U.S. federal withholding tax of 30% on certain payments paid to a “foreign financial institution” (as specifically defined by applicable rules) unless various U.S. information reporting and due diligence requirements (generally relating to ownership by United States persons of interests in or accounts with those entities) have been satisfied by the payee. FATCA also generally imposes a U.S. federal withholding tax of 30% on certain payments to a non-financial foreign entity unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding substantial direct and indirect U.S. owners of the entity. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. The withholding tax described above will not apply if the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from the rules.

FATCA withholding currently applies to payments of dividends on shares of our Common Stock. Withholding under FATCA was scheduled to apply to payments of gross proceeds from the sale of shares of our Common Stock beginning on January 1, 2019, but the U.S. Treasury Department has released proposed regulations which, if finalized in their present form, would eliminate such U.S. federal withholding tax of 30% applicable to the gross proceeds of a disposition of shares of our Common Stock. In its preamble to such proposed regulations, the U.S. Treasury Department stated that taxpayers may generally rely on the proposed regulations until final regulations are issued. Non-U.S. Holders are encouraged to consult with their own tax advisors regarding the possible implications of FATCA on their ownership and disposition of shares of our Common Stock.

Information Reporting and Backup Withholding

Information returns will be filed with the IRS in connection with payments of distributions on and the proceeds from a sale or other disposition of shares of our Common Stock. A Non-U.S. Holder generally will have to comply with certification procedures to establish that it is not a U.S. person in order to avoid information reporting and backup withholding requirements. The certification procedures required to claim a reduced rate of withholding under a treaty generally will satisfy the certification requirements necessary to avoid the backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against such Non-U.S. Holder’s U.S. federal income tax liability and may entitle such Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following table is an estimate of the expenses payable by us in connection with the securities being registered hereby. The SEC registration fee and certain other fees were previously paid in connection with the filing of the registration statement on Form S-1 (File No. 333-284266) with the SEC, to which this registration statement is Post-Effective Amendment No. 1.

*            These fees are calculated based on the securities offered and the number of issuances and accordingly cannot be determined at this time.

Discounts, concessions, commissions and similar selling expenses attributable to the sale of the securities covered by this prospectus will be borne by the selling securityholders. We will pay all expenses (other than discounts, concessions, commissions and similar selling expenses) relating to the registration of the securities with the SEC, as estimated in the table above.

Item 15. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities, including reimbursement for expenses incurred, arising under the Securities Act of 1933, as amended, or the Securities Act.

Our amended and restated certificate of incorporation provides for indemnification of our directors, officers, employees and other agents to the maximum extent permitted by the Delaware General Corporation Law, and our bylaws provide for indemnification of our directors, officers, employees and other agents to the maximum extent permitted by the Delaware General Corporation Law.

In addition, we have entered into indemnification agreements with our directors, officers, and some employees containing provisions which are in some respects broader than the specific indemnification provisions contained in the Delaware General Corporation Law. The indemnification agreements will require us, among other things, to indemnify our directors against certain liabilities that may arise by reason of their status or service as directors and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Item 16. Exhibits

* Filed herewith.

† Certain of the exhibits and schedules to this Exhibit have been omitted in accordance with Regulation S-K Item 601. The Company agrees to furnish a copy of all omitted exhibits and schedules to the SEC upon its request.

# Indicates a management contract or compensatory plan, contract or arrangement.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the undersigned pursuant to the foregoing provisions, or otherwise, the undersigned has 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. In the event that a claim for indemnification against such liabilities (other than the payment by the undersigned of expenses incurred or paid by a director, officer or controlling person of the undersigned in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the undersigned will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Post-Effective Amendment No. 1 to Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in Laguna Hills, California, on this 1st day of April, 2026.
