**461,286,233 ORDINARY SHARES and<br>3,545,210 WARRANTS**

#### OFFERED BY THE SELLING SECURITYHOLDERS
This prospectus relates to the issuance by us of up to 16,749,984 Ordinary Shares that may be issued upon exercise of Warrants to purchase Ordinary Shares, which were originally GHV Warrants that were automatically converted into Warrants upon consummation of the merger of Ardagh MP MergeCo Inc. ("MergeCo") with and into Gores Holdings V, Inc. ("GHV"), with GHV surviving the merger as a wholly owned subsidiary of the Company, which occurred on August 4, 2021 (the "Merger").

This prospectus also relates to the offer and sale from time to time by the Selling Securityholders, or their permitted transferees, of up to 461,286,233 Ordinary Shares and 3,545,210 Warrants to purchase Ordinary Shares, which were originally Private Placement Warrants that were automatically converted into Warrants upon consummation of the Merger.

We will receive proceeds from the exercise of the Warrants to the extent the Warrants are exercised for cash. We will not receive any proceeds from the sale of Ordinary Shares and Warrants by the Selling Securityholders pursuant to this prospectus. However, we will pay the expenses, other than underwriting commissions and discounts and expenses incurred by the Selling Securityholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholders in disposing of the securities, associated with the sale of Ordinary Shares pursuant to this prospectus.

Our registration of the securities covered by this prospectus does not mean that either we or the Selling Securityholders will issue, offer or sell, as applicable, any of the securities. The Selling Securityholders may offer and sell the securities covered by this prospectus in a number of different ways and at varying prices. We provide more information about how the Selling Securityholders may sell the securities in the section entitled "*Plan of Distribution*."

The Ordinary Shares and the Warrants are listed on the New York Stock Exchange (the "NYSE") under the symbols "AMBP" and "AMBP.WS," respectively. The last reported sale price of the Ordinary Shares was $3.77 per share on August 8, 2025, and the last reported sale price of the Warrants was $0.02 per warrant on August 8, 2025.

We are a "controlled company" under NYSE corporate governance rules and are eligible for certain exemptions from these rules. We are also a "foreign private issuer" under applicable SEC rules and are eligible for reduced public company disclosure requirements.

**You should read this prospectus and any prospectus supplement or amendment carefully before you invest in our securities. Investing in the Company's securities involves risks. See "*Risk Factors*" beginning on page** [**11**](#RISKFACTORS_462927) **of this prospectus and any risk factors described in any applicable prospectus supplement and in our SEC filings that are incorporated by reference in this prospectus.**

#### PROSPECTUS SUMMARY
This summary highlights selected information contained elsewhere in this prospectus or incorporated by reference in this prospectus. This summary does not contain all of the information you should consider before investing in the Company's securities. Before making an investment decision, you should read this entire prospectus carefully, especially the section entitled "Risk Factors", the financial statements and related notes thereto, the documents incorporated by reference in this prospectus and the other documents to which this prospectus refers. Some of the statements in this prospectus constitute forward-looking statements that involve risks and uncertainties. See "Cautionary Note Regarding Forward-Looking Statements" for more information. See also the section entitled "Where You Can Find More Information."

#### Ardagh Metal Packaging S.A.

#### Overview
We are one of the leading suppliers of consumer metal beverage cans in the world and believe that we hold the #2 or #3 market positions in Europe (excluding Russia, where we have no presence), the United States and Brazil. The global beverage can industry is a large, consumer-driven industry with attractive growth characteristics. Our end-use categories include beer, carbonated soft drinks, energy drinks, sparkling waters, hard seltzers, juices, pre-mixed cocktails, teas and wine. Our customers include a wide variety of leading beverage products, which value our packaging products for their convenience, quality and sustainability, as well as the end-user appeal they offer through design, innovation and brand promotion. With our significant invested capital base, supported by consistent levels of re-investment, our extensive technical capabilities and manufacturing know-how, we believe we are well-positioned to continue to meet the dynamic needs of our global customers.

#### Corporate Information
The Company was incorporated under the laws of Luxembourg on January 20, 2021 as a public limited liability company (*société anonyme*) having its registered office at 56, rue Charles Martel, L-2134 Luxembourg, Luxembourg and registered with the Luxembourg Register of Commerce and Companies (*Registre de Commerce et des Sociétés de Luxembourg*) under number B 251465.

#### Implications of Being a "Foreign Private Issuer" and a "Controlled Company"
The Company reports under the Exchange Act as a non-U.S. company with foreign private issuer status. As long as we continue to qualify as a foreign private issuer under the Exchange Act, we will be exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including:

● the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act;

● the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and

------

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

● the rules under the Exchange Act requiring the filing of quarterly reports with the SEC on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events.

In addition, we are not required to file annual reports and financial statements with the SEC as promptly as U.S. domestic companies whose securities are registered under the Exchange Act, and are not required to comply with Regulation FD, which restricts the selective disclosure of material information.

Further, we are exempt from certain corporate governance requirements of NYSE by virtue of being a foreign private issuer. As a foreign private issuer, we are permitted to follow the corporate governance practices of our home country in lieu of certain provisions of the NYSE Standards. Our intention is to voluntarily comply with these requirements, and as a result, there are currently no significant differences under the NYSE Standards between our corporate governance practices and those of U.S. domestic issuers listed on the NYSE.

We also qualify for and avail ourselves of certain of the controlled company exemptions under the NYSE Standards applicable to listed companies (both foreign private issuers and U.S. domestic issuers) as described in the NYSE Listed Company Manual. As a controlled company, we are not required to comply with the following requirements:

● a majority of the Board consist of independent directors;

● the nominating and governance committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities;

● the compensation committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; and

● there be an annual performance evaluation of the nominating and governance and compensation committees.

We currently comply with certain of these requirements on a voluntary basis, and as a result, the majority of our Board consists of independent directors, and we have written charters for and conduct annual performance evaluations of our nominating and governance committee and compensation committee. However, we currently avail ourselves of the exemption that allows our nominating and governance committee and compensation committee not to be composed entirely of independent directors.

There can be no assurance that we will not avail ourselves of other controlled company exemptions or cease voluntary compliance with the requirements we are exempt from due to our status as a foreign private issuer in the future.

#### CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus and the documents incorporated herein by reference include statements that are, or may be deemed to be, "forward-looking statements" within the meaning of the U.S. federal securities laws, including statements under the heading "*Risk Factors,*" statements of future expectations and other forward-looking statements. Forward-looking statements can be identified by the use of forward-looking terminology such as "aim," "anticipate," "believe," "continue," "could," "estimate," "expect," "forecast," "future," "guidance," "intend," "may," "opportunity," "plan," "potential," "predict," "projected," "should," "strategy," "suggests," "targets," "will," "will be" or "would" or similar expressions or the negatives thereof, or other variations thereof, or comparable terminology, or by discussions of strategy, plans or intentions. These forward-looking statements include all matters that are not historical facts. They appear in a number of places throughout this prospectus and include statements regarding the intentions, beliefs or current expectations of management concerning, among other things, results of operations, financial condition, liquidity, prospects, growth, strategies and the industry in which we operate.

You are cautioned that forward-looking statements are not guarantees of future performance and that actual results of operations, financial condition and liquidity, and the development of the industry in which the Company operates, may differ materially from those made in or suggested by the forward-looking statements contained in this prospectus. In addition, even if our results of operations, financial condition and liquidity, and the development of the industry in which we operate are consistent with the forward- looking statements contained in this prospectus, those results or developments may not be indicative of results or developments in subsequent periods.

By their nature, forward-looking statements involve known and unknown risks, uncertainties and other factors because they relate to events and depend on circumstances that may or may not occur in the future. Forward-looking statements are not guarantees of future performance and actual financial condition, results of operations and cash flows. The development of the industry in which the Company operates may differ materially from (and be more negative than) those made in, or suggested by, the forward-looking statements contained in this prospectus.

These statements are based on management's current views and assumptions and involve known and unknown risks and uncertainties that could cause actual results, performance or events to differ materially from those anticipated by such statements. You should not place undue reliance on these forward-looking statements. As a result of the number of known and unknown risks and uncertainties, actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Factors that could cause such differences in actual results include:

● an increase in metal beverage can manufacturing capacity without a corresponding increase in demand;

● competition from other metal packaging producers and alternative forms of packaging;

● concentration of our customers or suppliers, changes in our customers' or suppliers' strategic choices, such as whether to prioritize price or volume requirements;

● a significant write-down of goodwill;

● varied seasonal demands for our products and unseasonable weather conditions;

● changes in consumer lifestyle, nutritional preferences, health-related concerns and warnings, health-related drug developments, social media influence and consumer taxation;

● further consolidation of our existing customer base;

● availability and any increase in the costs of raw materials, including as a result of changes in tariffs and duties and our inability to fully pass through input costs;

------

[**Table of Contents**](#TOC)

● stability of energy supply and increase in energy prices, including in Europe as a result of the ongoing Russia-Ukraine war;

● our relationships with our suppliers, including maintenance of existing payment and credit terms, and reliance on their ability to make timely deliveries due to factors such as supply chain disruption;

● changes in the economic, political, credit, and/or financial environment in which we operate, which could have a material adverse effect on our business, such as reducing demand for our products;

● currency, interest rate and commodity price fluctuations;

● any pandemics or disease outbreaks that may have adverse impacts on worldwide economic activity and our business;

● interruption in the operations of our production facilities including through infrastructure failure caused by physical damage;

● acquisitions, including with respect to successful integration;

● organized strikes or work stoppages by our unionized employees;

● dependence on our executive and senior management, and other highly skilled personnel;

● costs and future funding obligations associated with post-retirement benefits provided to our employees;

● data protection, data breaches, cyberattacks on our IT systems and network disruptions, including the costs and reputational harm associated with such events;

● impact of climate change, both physical and transitional, as well as those associated with the failure to meet our sustainability targets;

● environmental, health and safety concerns, as well as legal, regulatory or other measures to address such concerns and associated costs to us;

● legislation and regulation, including costs of compliance and changes to laws and regulations governing our business;

● workplace injury and illness claims at our production facilities;

● failure of our control measures and systems that result in faulty or contaminated products and potential related reputational risk;

● litigation, arbitration and other proceedings;

● insufficient or prohibitively expensive insurance coverage;

● failure to maintain an effective system of disclosure controls and internal controls over financial reporting;

● our capital structure, including our substantial debt profile, ability to raise new financing or refinance existing financing, and ability to comply with the covenants in our financing agreements;

● risks relating to the Services Agreement;

------

[**Table of Contents**](#TOC)

● risks relating to the ownership of our Ordinary Shares, including those associated with the activities of our shareholders and our position as a company controlled by AGSA and our status as a Luxembourg company and a foreign private issuer; and

● other risks and uncertainties described or incorporated by reference in this prospectus, including those under "*Risk Factors*."

The Company undertakes no obligation to update publicly or release any revisions to these forward-looking statements to reflect events or circumstances or to reflect the occurrence of unanticipated events, other than as required by law.

The foregoing factors and others described under the section entitled "*Risk Factors*", as well as in the 2024 Form 20-F and in other documents that we may file with the SEC should not be construed as exhaustive. There are other factors that may cause our actual results to differ materially from the forward-looking statements contained in this prospectus. Moreover, new risks emerge from time to time and it is not possible for us to predict all such risks. We cannot assess the impact of all risks on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, you should not place undue reliance on forward-looking statements as a prediction of actual results. The Company urges you to read the section of this prospectus entitled "*Risk Factors*", as well as the documents incorporated by reference herein and any prospectus supplement for a more complete discussion of the factors that could affect its future performance and the industry in which it operates.

The forward-looking statements are based on plans, estimates and projections as they are currently available to the management of AMPSA, and we do not undertake any obligation nor expect to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements attributable to the Company or to persons acting on behalf of the Company are expressly qualified in their entirety by the cautionary statements referred to above and contained elsewhere in this prospectus or incorporated by reference herein.

#### RISK FACTORS
An investment in the Company's securities carries a significant degree of risk. Before you decide to purchase the Company's securities, you should carefully consider all risk factors set forth in any applicable prospectus supplement and the documents incorporated by reference in this prospectus, including the factors discussed under the heading "Risk Factors" in our most recent annual report on Form 20-F or any updates in our current reports on Form 6-K, which may be amended, supplemented or superseded from time to time by the other reports we file with the SEC in the future or by information in the applicable prospectus supplement. See "*Incorporation of Certain Documents by Reference*." The risks and uncertainties we have described are not the only risks we face. Additional risks and uncertainties of which we are not presently aware or that we currently deem immaterial could also affect our business operations and financial condition. If any of these risks actually occur, our business, financial condition, results of operations or prospects could be materially affected. As a result, the trading price of the Company's securities could decline and you could lose part or all of your investment.

#### DIVIDEND POLICY
The Board approved an interim dividend of $0.10 per Ordinary Share on April 22, 2025, which was paid on May 15, 2025 to shareholders of record on May 5, 2025. The Board approved an interim dividend of $0.10 per Ordinary Share on July 22, 2025, which will be paid on August 19, 2025 to shareholders of record on August 7, 2025. We intend to continue to pay an interim dividend on our Ordinary Shares on a quarterly basis; however, decisions in relation to our dividend policy are ultimately determined by our Board.

We paid an interim dividend on the annual 9% dividend of the Preferred Shares that was approved by the Board on April 22, 2025, which was paid on May 15, 2025. We paid an interim dividend on the annual 9% dividend of the Preferred Shares that was approved by the Board on July 22, 2025, which will be paid on August 19, 2025. Each Preferred Share is entitled to an annual preferred dividend per financial year of the Company amounting to 9% of its nominal value computed on the basis of a 360-day year comprised of twelve 30-day months (the "Annual Preferred Share Dividend"). The first pro rata Annual Preferred Share Dividend shall be calculated from the date of issuance of a Preferred Share (with the month of issuance being computed as a full month) until the end of the financial year of the date of issue, and all the subsequent Annual Preferred Share Dividend will be calculated per financial year of the Company. No distributions may be made to the holders of Ordinary Shares during a financial year if there is any Delta or New Delta (each as defined in "*Description of Securities — Shares — Preferred Shares*"), or unless all the Preferred Shares are redeemed, as described in "*Description of Securities — Shares — Preferred Shares*." The payment of dividends on the Preferred Shares is at the discretion of our Board.

#### DESCRIPTION OF SECURITIES
*The following description of our share capital summarizes certain provisions of the Articles. Such summaries do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of our Articles.*

#### General
AMPSA is a public limited liability company (*société anonyme*) incorporated and existing under the laws of the Grand Duchy of Luxembourg, having its registered office at 56, rue Charles Martel, L-2134 Luxembourg, Luxembourg and registered with the Luxembourg Register of Commerce and Companies (R.C.S. Luxembourg) under number B 251465.

The corporate objects of the Company are set out in the Articles. They are to be interpreted in the broadest sense and any transaction or agreement which is entered into by the Company that is not inconsistent with the specified objects will be deemed to be within the scope of such objects or powers.

#### Shares

#### Share Capital
AMPSA was incorporated on January 20, 2021 by AGSA, with an initial share capital of €30,000, represented by 3,000,000 ordinary shares with a nominal value of €0.01 per share.

AMPSA's current issued share capital equals €255,976,994.50, represented by 597,699,586 Ordinary Shares with a nominal value of €0.01 per share and 56,306,306 Preferred Shares with a nominal value of €4.44 per share (together, the "Shares"). All issued Shares are fully paid and subscribed for. The authorized capital of AMPSA (including the issued share capital) is set at €1,000,000,000, divided into 100,000,000,000 shares represented by Ordinary Shares and Preferred Shares. There are also 16,749,984 Warrants outstanding, each exercisable at $11.50 per Ordinary Share, subject to adjustment as described in the Warrant Agreement.

A shareholder in a Luxembourg *société anonyme* holding fully paid up shares is not liable, solely because of his, her or its shareholder status, for additional payments to AMPSA or its creditors.

#### Share Issuances
Pursuant to Luxembourg Law, the issuance of shares requires approval by the general meeting of shareholders subject to necessary quorum and majority requirements. The general meeting of shareholders or the Articles may also approve an authorized capital and authorize the Board to increase the issued share capital in one or several tranches with or without share premium, against payment in (i) cash, including the setting off of claims against AMPSA that are certain, due and payable, (ii) in kind, and (iii) reallocation of the share premium, profit reserves or other reserves of AMPSA, through issuance of shares, the granting of options to subscribe for shares, or the issuance of any other instruments convertible into or repayable by or exchangeable for shares (whether provided in the terms at issue or subsequently provided), the issuance of bonds with warrants or other rights to subscribe for shares attached, or the issuance of standalone warrants or any other instrument carrying an entitlement to, or the right to subscribe for, shares, up to a maximum of the authorized but as yet unissued share capital of AMPSA to such persons and on such terms as the Board determines in its absolute discretion. The Board can be authorized to remove or limit the statutory preferential subscription right of the shareholders in case of issue of shares up to the maximum amount of such authorized capital for a maximum period of five years after the date that the minutes of the relevant general meeting approving such authorization are published in the Luxembourg official gazette (*Recueil Electronique des Sociétés et Associations*, "RESA"). The general meeting may amend, renew, or extend such authorized capital and such authorization to the Board to issue shares.

------

[**Table of Contents**](#TOC)

The Articles authorize the Board to issue shares up to the maximum amount of the authorized unissued share capital of the AMPSA and to limit or withdraw any and all statutory preemptive rights which would be applicable in respect of such issuance for a period of five years from July 8, 2022, to such persons, on such terms and for such consideration as the Board determines in its absolute discretion. Shareholders may at a general meeting renew or extend such authorized share capital and authorization to the Board to issue shares.

In addition, the general meeting of shareholders may authorize the Board to make an allotment of existing or newly issued shares without consideration to (a) employees of AMPSA or certain categories amongst those; (b) employees of companies or economic interest grouping in which AMPSA holds directly or indirectly at least ten percent (10%) of the share capital or voting rights; (c) employees of companies or economic interest grouping holding directly or indirectly at least ten percent (10%) of the share capital or voting rights of AMPSA; (d) employees of companies or economic interest grouping in which at least fifty percent (50%) of the share capital or voting rights is held directly or indirectly by a company which holds directly or indirectly at least fifty percent (50%) of the share capital of AMPSA; (e) corporate officers of AMPSA or of the companies or economic interest grouping listed in points (b) to (d) above or certain categories amongst those, for a maximum period of five years after the date that the minutes of the relevant general meeting approving such authorization are published in the RESA.

The Articles authorize the Board to issue shares free of charge within the limitations set out in article 430-15 of the Luxembourg law of August 10, 1915 on commercial companies, as amended (the "1915 Law").

AMPSA recognizes only one (1) holder per share. In case a share is owned by several persons, AMPSA shall treat the first named holder on the register of shareholders as having been appointed by the joint holders to receive all notices and to give a binding receipt for any dividend(s) payable in respect of such share(s) on behalf of all joint holders, without prejudice to the rights of the other holders to information as set out in the 1915 Law.

The Board resolves on the issuance of shares out of the authorized capital (*capital autorisé*) in accordance with the quorum and voting thresholds set forth in the Articles and applicable law. The Board also resolves on the applicable procedures and timelines to which such issuance is subjected. If the proposal of the Board to issue new shares exceeds the limits of AMPSA's authorized share capital, the Board must then convene the shareholders to an extraordinary general meeting to be held in front of a Luxembourg notary for the purpose of increasing the issued share capital. Such meeting will be subject to the quorum and majority requirements required for amending the Articles. If the capital call proposed by the Board consists of an increase in the shareholders' commitments, the Board must convene the shareholders to an extraordinary general meeting to be held in front of a Luxembourg notary for such purpose. Such meeting will be subject to the unanimous consent of the shareholders.

#### Preferred Shares
All Preferred Shares are issued in the form of redeemable shares and are redeemable at the sole discretion of the Company at such date as decided by the Board. The holders of Preferred Shares have no right to request the redemption of their Preferred Shares. Without prejudice to the conditions set forth in the 1915 Law, the Preferred Shares will be redeemed pursuant to Article 8 of the Articles and by serving a Notice (the "Purchase Notice") to the owner of the Preferred Shares to be repurchased, specifying the Preferred Shares to be repurchased, the purchase price to be paid for such Preferred Shares and the place at which the purchase price in respect of such Preferred Shares is payable. Immediately after the close of business on the date specified in the Purchase Notice such holder shall cease to be the holder of the Preferred Shares specified in such Purchase Notice and its name shall be removed as the holder of such Preferred Shares from the Register of Shareholders. Any such holder will cease to have any right as a shareholder with respect to the Preferred Shares to be repurchased as from the date specified in the Purchase Notice.

Each Preferred Share is entitled to an annual preferred dividend amounting to 9% of its nominal value computed on the basis of a 360-day year comprised of twelve 30-day months (the "Annual Preferred Share Dividend"). The first pro rata Annual Preferred Share Dividend shall be calculated from the date of issuance of a Preferred Share (with the month of issuance being computed as a full month) until the end of the financial year of the date of issue, and all the subsequent Annual Preferred Share Dividend will be calculated per financial year of the Company. The entitlement to the Annual Preferred Share Dividend only becomes payable if and when such dividend is declared and then at such date as shall be

------

[**Table of Contents**](#TOC)

determined by the Board in its discretion. If at the end of a financial year, the Annual Preferred Share Dividend has not been declared or paid in full, the difference between the Annual Preferred Share Dividend and the portion of the Annual Preferred Share Dividend effectively paid (the "Delta") shall be rolled-over until the next financial year(s) but can also be deferred indefinitely by the Board in its sole discretion subject to Articles 15.4, 8.6 and 6.5 of the Articles. The Delta shall be set at the Annual Preferred Share Dividend if no Annual Preferred Share Dividend is approved at any annual general meeting or otherwise paid by way of an interim dividend during a financial year. If any Delta exists at the beginning of a financial year, any payment made on the Preferred Share will first be applied in reimbursement of such Delta and if such Delta and the Annual Preferred Share Dividend of the relevant financial year are not paid in full on the last day of such financial year, the difference will constitute a new Delta (a "New Delta") rolled-over to the next financial year.

No distributions may be made to the holders of Ordinary Shares during a financial year if there is any Delta or New Delta, or unless all the Preferred Shares are redeemed.

#### Preemptive Rights
Under Luxembourg Law, existing shareholders benefit from a preemptive subscription right on the issuance of shares for cash consideration. However, AMPSA's shareholders have, in accordance with Luxembourg Law, authorized the Board to suppress, waive, or limit any preemptive subscription rights of shareholders provided by law to the extent that the Board deems such suppression, waiver, or limitation advisable for any issuance or issuances of shares within the scope of AMPSA's authorized share capital. The general meeting of shareholders duly convened to consider an amendment to the Articles also may, by two-thirds majority vote, limit, waive, or cancel such preemptive rights or renew, amend, or extend them, in each case for a period not to exceed five years. Such shares may be issued above, at, or below market value, and, following a certain procedure, even below the nominal value or below the accounting par value per share. The shares also may be issued by way of incorporation of available reserves, including share premium.

#### Share Repurchases
AMPSA cannot subscribe for its own shares. AMPSA may, however, repurchase issued shares or have another person repurchase issued shares for its account, subject to the following conditions:

● prior authorization by a simple majority vote at an ordinary general meeting of shareholders, which authorization sets forth:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o the terms and conditions of the proposed repurchase and in particular the maximum number of shares to be repurchased;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o the duration of the period for which the authorization is given, which may not exceed five years; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o in the case of repurchase for consideration, the minimum and maximum consideration per share, provided that the prior authorization shall not apply in the case of shares acquired by either AMPSA, or by a person acting in his or her own name on its behalf, for the distribution thereof to its staff or to the staff of a company with which it is in a control relationship;

● only fully paid-up shares may be repurchased;

● the voting rights attached to the repurchased shares will be suspended as long as the repurchased shares are held by AMPSA, the Board may decide to suspend the right to dividends attached to such repurchased shares; and the acquisition offer must be made on the same terms and conditions to all the shareholders who are in the same position, except for acquisitions which were unanimously decided by a general meeting at which all the shareholders were present or represented. In addition, listed companies may repurchase their own shares on the stock exchange without an acquisition offer having to be made to AMPSA's shareholders.

------

[**Table of Contents**](#TOC)

The authorization will be valid for a period ending on the earlier of five years from the date of such shareholder authorization and the date of its renewal by a subsequent general meeting of shareholders. Pursuant to such authorization, the Board is authorized to acquire and sell AMPSA's shares under the conditions set forth in article 430-15 of the 1915 Law, which are described above. Such purchases and sales may be carried out for any authorized purpose or any purpose that is authorized by the laws and regulations in force.

The Articles authorize the Board to purchase AMPSA's own shares in accordance with Luxembourg Law on such terms and in such manner as may be authorized by the general meeting of shareholders in an ordinary resolution, subject to the rules of any stock exchange on which the Ordinary Shares are traded. The Articles provide that the Board is authorized for a period of 5 years from July 8, 2022 to make (i) open market repurchases of shares subject to certain conditions, and (ii) repurchases of shares other than as described in (i) where the same terms are offered to all shareholders in a similar situation, it being understood that holders of Preferred Shares shall not be deemed to be in a similar situation to holders of Ordinary Shares.

In addition, pursuant to Luxembourg Law, AMPSA may directly or indirectly repurchase shares by resolution of the Board without the prior approval of the general meeting of shareholders if such repurchase is deemed by the Board to be necessary to prevent serious and imminent harm to AMPSA, or if the acquisition of shares has been made with the intent of distribution to its employees and/or the employees of any entity having a controlling relationship with it (i.e., its subsidiaries or controlling shareholder) or in any of the circumstances listed in article 430-16 of the 1915 Law.

#### Voting Rights
Each Ordinary Share entitles the holder thereof to one vote. Neither Luxembourg Law nor the Articles contain any restrictions as to the holding or voting of Ordinary Shares by non-Luxembourg residents. Luxembourg Law does not provide for cumulative voting in the election of directors. Voting of shareholders holding Ordinary Shares at a general meeting may be in person, by proxy or by voting form. The Articles specify how the Company shall determine the shareholders of record entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof.

The Preferred Shares are non-voting shares. Any shareholder who holds one or more Preferred Share(s) may attend a shareholders meeting in person or be represented by proxy, but cannot vote. The Preferred Shares will not be taken into account for determining the quorum for items submitted to vote to the shareholders save for very specific situations set out in the 1915 Law in which holders of non-voting shares shall be entitled to vote (i.e. where the deliberation of the general meeting is such that it may result in an increase of the commitments of the shareholders or an amendment of the rights attaching to the non-voting shares as well as in any general meeting called upon to decide on the reduction of capital or on the early dissolution of the Company).

The Articles distinguish ordinary resolutions and special resolutions.

*Ordinary Resolutions*. The Articles (to be read in conjunction with Luxembourg Law) require a quorum of at least one-third (1/3) of the voting shares in issue present in person or by proxy, for any ordinary resolutions to be considered at a general meeting, and such ordinary resolutions are adopted by a simple majority of votes validly cast on such resolution by shareholders entitled to vote. Abstentions and nil votes are not taken into account.

*Special Resolutions*. The Articles require special resolutions adopted at an extraordinary general meeting for any of the following matters, among other things: (i) an increase or decrease of the authorized or issued capital, (ii) an amendment to the Articles and (iii) dissolving the Company. Pursuant to the Articles (to be read in conjunction with Luxembourg Law), for any special resolutions to be considered at an extraordinary general meeting the quorum is at least one-half (1/2) of the voting shares in issue present in person or by proxy, unless otherwise mandatorily required by the 1915 Law. Any special resolution may be adopted at an extraordinary general meeting at which a quorum is present, subject to the 1915 Law, by the affirmative vote of holders of at least two-thirds (2/3) of the votes validly cast on such resolution by shareholders entitled to vote.

------

[**Table of Contents**](#TOC)

AGSA, our parent company, by virtue of its indirect ownership of approximately 76% of our Ordinary Shares and its indirect ownership of 100% of our Preferred Shares, can control the outcome of any action requiring the general approval of our shareholders.

The Board may suspend the right to vote of any shareholder if such shareholder fails to fulfill its obligations under the Articles or any deed of subscription or deed of commitment entered into by such shareholder.

#### Amendment of the Articles
Except where the Articles authorize the Board to approve an increase or a reduction in share capital and subsequently record such change within thirty (30) days in the presence of a Luxembourg notary, the Articles require a special resolution approved at an extraordinary general meeting of shareholders to amend the Articles. The agenda of the extraordinary general meeting of shareholders must indicate the proposed amendments to the Articles. Any resolutions to amend the Articles must be taken before a Luxembourg notary and such amendments must be published in accordance with the 1915 Law.

#### Annual Shareholders Meetings
An annual general meeting of shareholders shall be held in the Grand Duchy of Luxembourg within 6 months of the end of the preceding financial year.

#### Distributions on Winding up of the Company
Any voluntary dissolution of the Company will take place in accordance with the provisions of Luxembourg Law. The Company may only be placed into voluntary dissolution if shareholders holding Ordinary Shares and Preferred Shares vote in favor of such dissolution by means of a special resolution passed at an extraordinary general meeting.

In the event of our liquidation, dissolution or winding up, the holders of shares are entitled to share as set forth in our Articles.

Because all shares of the Company will be fully paid, shareholders will have no liability in the event of a winding up of the Company, unless they are deemed to be a de facto manager (*gérant de fait*) exercising effective and continuing control over the Company by positive actions.

#### Mergers and De-mergers
A merger by absorption whereby a Luxembourg company, after its dissolution without liquidation, transfers to the absorbing company all of its assets and liabilities in exchange for the issuance to the shareholders of the company being acquired of shares in the acquiring company, or a merger effected by transfer of assets to a newly incorporated company, must, in principle, subject to certain exceptions, be approved by a special resolution of shareholders of the Luxembourg company to be held before a notary. Similarly, a de-merger of a Luxembourg company is, in principle, subject to certain exceptions subject to the approval by a special resolution of shareholders.

#### Compulsory Transfer of Ordinary Shares
The Articles provide that at any time a person is or becomes, directly or indirectly, the owner of 75% or more of the number of issued Ordinary Shares of the Company, such person (the "Acquiror") may require, by giving notice to the Company as specified in the Articles, the holders of the remaining issued Ordinary Shares of the Company to sell their Ordinary Shares to the Acquiror for cash at a price that reflects the fair market value of such Ordinary Shares as initially determined by an independent investment banking firm of international reputation retained by the Acquiror. The Articles contain procedures for determining the fair market value of the Ordinary Shares held by the minority shareholders, which include a dispute resolution provision permitting holders of at least 10% of the remaining Ordinary Shares of the Company to dispute the purchase price proposed by the Acquiror in accordance with the procedures set forth in the Articles.

#### Anti-Takeover Provisions
See the section entitled "*Risk Factors — Risks Related to Being a Luxembourg Company and Our Status as a Foreign Private Issuer — Anti-takeover provisions in our Articles might discourage or delay attempts to acquire it.*" in the [2024 Form 20-F](https://www.sec.gov/ix?doc=/Archives/edgar/data/1845097/000155837025002142/ambp-20241231x20f.htm) incorporated by reference into this prospectus.

#### Shareholder Suits
Class actions and derivative actions are generally not available to shareholders under Luxembourg Law. Minority shareholders holding securities entitled to vote at the general meeting that resolved on the granting of discharge to the directors, holding at least the 10% threshold (of the subscribed capital) may bring an action against the directors on behalf of the Company. Minority shareholders holding at least the 10% threshold (of the subscribed capital) may also ask the directors questions in writing concerning acts of management of the Company or one of its subsidiaries, and if the Company fails to answer these questions within one month, these shareholders may apply to the Luxembourg courts to appoint one or more experts instructed to submit a report on these acts of management. Furthermore, consideration would be given by a Luxembourg court in summary proceedings to acts that are alleged to constitute an abuse of majority rights against the minority shareholders.

The Articles contain a provision providing for the waiver by each of our shareholders of any claim or right of action they have, both individually and on the Company's behalf, against any director or officer in relation to any action or failure to take action by such director or officer, except in respect of any matter involving fraud or dishonesty, gross negligence, willful misconduct or action giving rise to criminal liability that may attach to such director or officer.

#### Interested Directors
The Articles contain specific provisions regarding interested directors and set forth procedures for approval of contracts or transactions involving an interested director. If a director has a direct or indirect financial interest conflicting with that of the Company in any contract or transaction to which the Company will be party, such interested director shall advise the Board thereof, cause a record of his or her statement to be included in the minutes of the meeting, and may not take part in the deliberations of the Board or any Board committee with respect to such contract or transaction and the Articles contain specific quorum and majority rules for meetings of the Board or its committees in case of conflicted directors. Such provisions do not apply to any contract or transaction that is within the ordinary course of business of the Company or its subsidiaries and is entered into on an arms' length basis under market conditions.

#### Competition and Corporate Opportunities
The Articles contain specific provisions regarding competition and the allocation of corporate opportunities that are applicable to members of the Board who are not employees of the Company, as well as their respective Affiliates and Affiliated Entities (each as defined in the Articles), in recognition and anticipation that members of the Board who are not employees of the Company and their respective Affiliates and Affiliated Entities may engage in the same or similar activities or related lines of business as those in which the Company, directly or indirectly, may engage or other business activities that overlap with or compete with those in which the Company, directly or indirectly, engages.

#### Warrants
Pursuant to the Warrant Assignment, Assumption and Amendment Agreement, GHV assigned to AMPSA all of GHV's right, title and interest in and to the existing Warrant Agreement and AMPSA assumed, and agreed to pay, perform, satisfy and discharge in full, all of GHV's liabilities and obligations under the existing Warrant Agreement arising from and after the August 4, 2021.

As of December 31, 2024, there were 16,749,984 Warrants outstanding. Each Warrant is exercisable to subscribe for one Ordinary Share and only whole Warrants are exercisable. The exercise price of the Warrants is $11.50 per Ordinary Share, subject to adjustment as described in the Warrant Agreement. A Warrant may be exercised only during the period commencing on the later of (i) the date that is thirty (30) days after the consummation of the Merger, or

------

[**Table of Contents**](#TOC)

(ii) the date that is twelve (12) months from the IPO and terminating at 5:00 p.m., New York City time on the earlier to occur of: (x) the date that is five (5) years after the date on which the Merger is completed, or (y) the redemption date as provided in Section 6.3 of the Warrant Agreement.

#### Redemption of Warrants for Cash
Pursuant to the Warrant Agreement, the public warrants may be redeemed (i) in whole and not in part, (ii) at a price of $0.01 per warrant, (iii) upon not less than 30 days' prior written notice of redemption to each warrant holder, and (iv) if, and only if, the reported last sale price of the Ordinary Shares equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before sending the notice of redemption to each warrant holder.

If the public warrants are called for redemption for cash, management will have the option to require all holders that wish to exercise the public warrants to do so on a "cashless basis," as described in the Warrant Agreement.

#### Redemption of Warrants for Ordinary Shares
AMPSA may redeem the outstanding Warrants (i) in whole and not in part, (ii) upon a minimum of 30 days' prior written notice of redemption at a price equal to a number of Ordinary Shares to be determined by reference to the table contained in Section 6.2 of the Warrant Agreement, based on the redemption date and the fair market value of the Ordinary Shares, (iii) if, and only if, the last reported sale price of the Ordinary Shares equals or exceeds $10.00 per Ordinary Share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which the notice of redemption to the warrant holders is sent, (iv) if, and only if, the private warrants are also concurrently exchanged at the same price (equal to a number of Ordinary Shares) as the outstanding public warrants, and (v) if, and only if, there is an effective registration statement covering the Ordinary Shares issuable upon exercise of the Warrants and a current prospectus relating thereto is available throughout the 30-day period after the written notice of redemption is given.

The private warrants are identical to the public warrants, except that the private warrants and the Ordinary Shares issuable upon the exercise of the private warrants were not transferable, assignable or salable until 30 days after the completion of the Merger, subject to certain limited exceptions. Additionally, the private warrants are exercisable on a cashless basis and are non-redeemable (except as mentioned above) so long as they are held by the initial purchasers or their permitted transferees. If the private warrants are held by someone other than the initial purchasers or their permitted transferees, the private warrants will be redeemable and exercisable by such holders on the same basis as the public warrants.

The foregoing description of the Warrants is qualified in its entirety by reference to the full text of the Warrant Agreement, filed as Exhibit 4.7 to the registration statement of which this prospectus forms a part, and the Warrant Assignment, Assumption and Amendment Agreement, filed as Exhibit 4.8 to the registration statement of which this prospectus forms a part.

#### Dividends
From the annual net profits of AMPSA, at least 5% shall each year be allocated to the reserve required by applicable laws (the "Legal Reserve"). That allocation to the Legal Reserve will cease to be required as soon and as long as the Legal Reserve amounts to 10% of the amount of the share capital of AMPSA. The general meeting of shareholders shall resolve how the remainder of the annual net profits, after allocation to the Legal Reserve, will be disposed of by allocating the whole or part of the remainder to a reserve or to a provision, by carrying it forward to the next following financial year or by distributing it, together with carried forward profits, distributable reserves or share premium to the holders of Ordinary Shares. No distributions may be made to the holders of Ordinary Shares during a financial year if there is any Delta or New Delta (each as defined in our Articles), or unless all the Preferred Shares are redeemed, as described in our Articles.

The Board may resolve that AMPSA pays out an interim dividend to the shareholders, subject to the conditions of article 461-3 of the 1915 Law and the Articles. The Board shall set the amount and the date of payment of the interim dividend. Any interim dividends declared by the Board and paid during a financial year will be put to the shareholders at the following general meeting to be declared as final.

Subject to applicable laws and regulations, in order for AMPSA to determine which shareholders shall be entitled to receipt of any dividend, the Board may fix a record date, which record date will be the close of business (or such other time as the Board may determine) on the date determined by the Board. In the absence of a record date being fixed, the record date for determining shareholders entitled to receipt of any dividend shall the close of business in Luxembourg on the day the dividend is declared.

Any share premium, assimilated premium or other distributable reserve may be freely distributed to the shareholders subject to the provisions of the 1915 Law and the Articles. In case of a dividend payment, each shareholder is entitled to receive a dividend right pro rata according to his or her respective shareholding. The dividend entitlement lapses upon the expiration of a five-year prescription period from the date of the dividend distribution. The unclaimed dividends return to AMPSA's accounts.

No distributions may be made to the holders of Ordinary Shares during a financial year if there is any Delta or New Delta, or unless all the Preferred Shares are redeemed. See "Preferred Shares" in this section.

#### Registrar, Transfer and Warrant Agent
The registrar and transfer agent for the Ordinary Shares and the warrant agent for the Warrants is Computershare Trust Company, N.A.

| **SPECIAL VOTE REQUIRED FOR COMBINATIONS WITH INTERESTED SHAREHOLDERS** | Section 203 of the DGCL generally prohibits a Delaware corporation from engaging in specified corporate transactions (such as mergers, stock and asset sales, and loans) with an "interested stockholder" for three years following the time that the stockholder becomes an interested stockholder. Subject to specified exceptions, an "interested stockholder" is a person or group that owns 15% or more of the corporation's outstanding voting stock (including any rights to acquire stock pursuant to an option, warrant, agreement, arrangement, or understanding, or upon the exercise of conversion or exchange rights, and stock with respect to which the person has voting rights only), or is an affiliate or associate of the corporation and was the owner of 15% or more of the voting stock at any time within the previous three years. | Under Luxembourg Law, no restriction exists as to the transactions that a shareholder may engage in with AMPSA. The transaction must, however, be in AMPSA's corporate interest, which for instance requires that the transactions are made on arm's length terms.<br>|
| **SHAREHOLDER RIGHTS PLAN** | Under the DGCL, the certificate of incorporation of a corporation may give the board of directors the right to issue new classes of preferred shares with voting, conversion, dividend distribution, and other rights to be determined by the board of directors at the time of issuance, which could prevent a takeover attempt and thereby preclude stockholders from realizing a potential premium over the market value of their shares.<br>In addition, Delaware law does not prohibit a corporation from adopting a stockholder rights plan, or "poison pill," which could prevent a takeover attempt and also preclude stockholders from realizing a potential premium over the market value of their shares.<br>| Pursuant to Luxembourg Law, the shareholders may create an authorized share capital which allows the Board to increase the issued share capital in one or several tranches with or without share premium, against payment in (i) cash, including the setting off of claims against AMPSA that are certain, due and payable, (ii) in kind, and (ii) reallocation of the share premium, profit reserves or other reserves of AMPSA, through issuance of shares, the granting of options to subscribe for shares, or the issuance of any other instruments convertible into or repayable by or exchangeable for shares (whether provided in the terms at issue or subsequently provided), the issuance of bonds with warrants or other rights to subscribe for shares attached, or the issuance of standalone warrants or any other instrument carrying an entitlement to, or the right to subscribe for, shares, up to a maximum of the authorized but as yet unissued share capital of AMPSA to  |

The authorization may be renewed, increased or reduced by a resolution of the extraordinary general meeting of shareholders, with the quorum and majority rules set for the amendment of the Articles.<br>The Articles authorize the Board to issue new shares, to grant options to subscribe for new shares, to issue any other instruments convertible into or repayable by or exchangeable for new shares (whether provided in the terms at issue or subsequently provided), to issue bonds with warrants or other rights to subscribe for new shares attached, or through the issue of standalone warrants or any other instrument carrying an entitlement to, or the right to subscribe for, new shares, up to a maximum of the authorized but as yet unissued share capital of the Company to such persons and on such terms as the Board determines in its absolute discretion AMPSA for a period ending five years after July 8, 2022 unless such period is extended, amended or renewed. Accordingly, the Board is authorized to issue shares up to the limits of authorized share capital until such date. AMPSA currently intends to seek renewals and/or extensions as required from time to time. |
| **APPRAISAL RIGHTS** | Under the DGCL, a stockholder of a corporation participating in some types of major corporate transactions may, under varying circumstances, be entitled to appraisal rights pursuant to which the stockholder may receive cash in the amount of the fair market value of his or her shares in lieu of the consideration he or she would otherwise receive in the transaction. | Neither Luxembourg Law nor the Articles provide for appraisal rights. |

| **SHAREHOLDER CONSENT TO ACTION WITHOUT MEETING** | Under the DGCL, unless otherwise provided in a corporation's certificate of incorporation, any action that may be taken at a meeting of stockholders may be taken without a meeting, without prior notice, and without a vote if the holders of outstanding stock, having not less than the minimum number of votes that would be necessary to authorize such action, consent in writing. | A shareholder meeting must always be called if the matter to be considered requires a shareholder resolution under Luxembourg Law or the Articles.<br>Pursuant to Luxembourg Law, shareholders of a public limited liability company may not take actions by written consent. All shareholder actions must be approved at an actual meeting of shareholders held before a Luxembourg notary public or under private seal, depending on the nature of the matter.<br>Shareholders may vote in person, by proxy or, if the articles of association provide for that possibility, by correspondence.<br>The Articles provide for the possibility of vote in writing (by way of a voting form provided by the Company) on resolutions submitted to the general meeting, provided that the voting form includes (a) the name, first name, address and the signature of the relevant AMPSA shareholder, (b) the indication of the shares for which the AMPSA shareholder will exercise such right, (c) the agenda as set forth in the convening notice and (d) the voting instructions (approval, refusal, abstention) for each point of the agenda. |
| **MEETINGS OF SHAREHOLDERS** | Under the DGCL, a special meeting of stockholders may be called by the board of directors or by any other person authorized to do so in the certificate of incorporation or the bylaws.<br>Under the DGCL, a corporation's certificate of incorporation or bylaws can specify the number of shares that constitute the quorum required to conduct business at a meeting, provided that in no event shall a quorum consist of less than one-third of the shares entitled to vote at a meeting. | Pursuant to Luxembourg Law, at least one general meeting of shareholders must be held each year, within six months as from the close of the financial year. The purpose of such annual general meeting is to approve the annual accounts, allocate the results, proceed to statutory appointments and resolve on the discharge of the directors.<br>Other general meetings of shareholders may be convened.<br>Luxembourg Law distinguishes between ordinary resolutions to be adopted and extraordinary resolutions to be adopted by the general meeting of shareholders.

|  |  | The 1915 Law provides that if, as a result of losses, net assets fall below half of the share capital of the company, the Board shall convene an extraordinary general meeting of shareholders so that it is held within a period not exceeding two months from the time at which the loss was or should have been ascertained by them and such meeting shall resolve on the possible dissolution of the company and possibly on other measures announced in the agenda. The Board shall, in such situation, draw up a special report which sets out the causes of that situation and justify its proposals eight days before the extraordinary general meeting. If it proposes to continue to conduct business, it shall set out in the report the measures it intends to take in order to remedy the financial situation of the company. The same rules apply if, as a result of losses, net assets fall below one-quarter of the share capital provided that in such case dissolution shall take place if approved by one-fourth of the votes casts at the extraordinary general meeting. |
| **DISTRIBUTIONS AND DIVIDENDS; REPURCHASES AND REDEMPTIONS** | Under the DGCL, the board of directors, subject to any restrictions in the corporation's certificate of incorporation, may declare and pay dividends out of:<br>· surplus of the corporation, which is defined as net assets less statutory capital; or<br>· if no surplus exists, out of the net profits of the corporation for the year in which the dividend is declared and/or the preceding year.<br>If, however, the capital of the corporation has been diminished by depreciation in the value of its property, or by losses, or otherwise, to an amount less than the aggregate amount of capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets, the board of  | Under Luxembourg Law, the amount and payment of annual dividends or other distributions is determined by a simple majority vote at a general shareholders' meeting based on the recommendation of the Board. Pursuant to the Articles, the Board has the power to pay interim dividends or make other distributions in accordance with applicable Luxembourg Law. Distributions may be lawfully declared and paid if AMPSA's net profits and/or distributable reserves are sufficient under Luxembourg Law. No distributions may be made to the holders of the Ordinary Shares so long as the preferred dividend due to the holders of Preferred Shares has not been paid in accordance with the Articles or unless the Preferred Shares are redeemed.<br>Under Luxembourg Law, at least 5% of AMPSA's net profits per year must  |

In addition, listed companies may repurchase their own shares on the stock exchange without an acquisition offer having to be made to AMPSA's shareholders.<br>No prior authorization by shareholders is required (i) if the acquisition is made to prevent serious and imminent harm to AMPSA, provided that the Board informs the next general meeting of the reasons for and the purpose of the acquisitions made, the number and nominal values or the accounting value of the shares acquired, the proportion of the subscribed capital which they represent, and the consideration paid for them, and (ii) in the case of shares acquired by either AMPSA or by a person acting on its behalf with a view to redistributing the shares to its staff or staff of its controlled subsidiaries, provided that the distribution of such shares is made within twelve months from their acquisition.<br>Luxembourg Law provides for further situations in which the above conditions do not apply, including the acquisition of shares pursuant to a decision to reduce AMPSA's share capital or the acquisition of shares issued as redeemable shares. Such acquisitions may not have the effect of reducing net assets below the aggregate of subscribed capital and reserves (which may not be distributed by law) and are subject to specific provisions on reductions in share capital and redeemable shares under Luxembourg Law.<br>Any shares acquired in contravention of the above provisions must be resold  |

Further, to the extent the treasury shares are reflected as assets on AMPSA's balance sheet a non-distributable reserve of the same amount must be reflected as a liability.<br>The Articles authorize the Board to purchase AMPSA's own shares in accordance with Luxembourg Law on such terms and in such manner as may be authorized by the general meeting of shareholders in an ordinary resolution, subject to the rules of any stock exchange on which AMPSA's Ordinary Shares are traded. The Articles provide that the Board is authorized for a period of 5 years from July 8, 2022 to make (i) open market repurchases of Ordinary Shares subject to certain conditions and (ii) repurchases of shares other than as described in (i) where the same terms are offered to all shareholders in a similar situation, it being understood that holders of Preferred Shares shall not be deemed to be in a similar situation to holders of Ordinary Shares. |

In such circumstances, the next general meeting shall make the final appointment. The decision to fill a vacancy is taken by the remaining directors by simple majority vote.<br>The Articles provide that in case of a vacancy the remaining members of the Board may elect a director to fill the vacancy. A director so appointed shall be appointed to the class of directors that the director he or she is replacing belonged to, provided that such director shall hold office only until ratification by the shareholders of his or her appointment at the next following general meeting and, if such general meeting does not ratify the appointment, such director shall vacate his or her office at the conclusion thereof. |

The Class I Directors are appointed for a one (1) year term of office, the Class II Directors are appointed for a two (2) year term of office and the Class III Directors are appointed for a three (3) year term of office. At each succeeding annual general meeting, successors to the class of Directors whose term expires at that annual general meeting shall be elected for a three (3) year term of office. |

When directors are elected by cumulative voting, a stockholder has a number of votes equal to the number of shares held by such stockholder multiplied by the number of directors nominated for election. The stockholder may cast all of such votes for one director or among the directors in any proportion.<br>| Not applicable. |
| **AMENDMENT OF GOVERNING DOCUMENTS** | Under the DGCL, a certificate of incorporation may be amended if:<br>· the board of directors sets forth the proposed amendment in a resolution, declares the advisability of the amendment and directs that it be submitted to a vote at a meeting of stockholders; and<br>· the holders of at least a majority of shares of stock entitled to vote on the matter approve the amendment, unless the certificate of incorporation requires the vote of a greater number of shares.<br>In addition, under the DGCL, class voting rights exist with respect to amendments to the charter that adversely affect the terms of the shares of a class.

If the said quorum is not present, a second meeting may be convened at which Luxembourg Law does not prescribe a quorum. Any extraordinary resolution shall be adopted at a quorate general meeting (save as otherwise provided by mandatory law) by a two-thirds majority of the votes validly cast on such resolution by shareholders. Abstentions are not considered "votes."<br>In very limited circumstances, the Board may be authorized by the shareholders to amend the articles of association, albeit always within the limits set forth by the shareholders at a duly convened shareholders' meeting.

The DGCL permits a corporation to advance expenses relating to the defense of any proceeding to directors and officers contingent upon those individuals' commitment to repay any advances, unless it is determined ultimately that those individuals are entitled to be indemnified. |  |
| **LIMITED LIABILITY OF DIRECTORS AND CERTAIN OFFICERS** | Delaware law permits limiting or eliminating the monetary liability of a director and certain officers to a corporation or its stockholders for breach of fiduciary duty as a director or officer, except with regard to breaches of duty of loyalty, any act or omission not in good faith or which involves intentional misconduct or a knowing violation of the law, with respect to directors, any liability under section 174 of the DGCL which relates to the payment of unlawful dividends and unlawful stock purchases or redemptions, or with respect to  | Luxembourg Law does not provide for an *ex ante* limitation of liability but it permits AMPSA to keep directors or officers indemnified as set out above. |

In addition, advance notice bylaws frequently require the stockholder nominating a person for election to the board of directors to provide information about the nominee, such as his or her age, address, employment and beneficial ownership of shares of the corporation's capital stock. The stockholder may also be required to disclose, among other things, his or her name, share ownership and agreement, arrangement or understanding with respect to such nomination.<br>For other proposals, the proposing stockholder is often required by the bylaws to provide a description of the proposal and any other information relating to such stockholder or beneficial owner, if any, on whose behalf that proposal is being made, required to be disclosed in a proxy statement or other filings required to be made in connection with solicitation of proxies for the proposal and pursuant to and in accordance with the Exchange Act and the rules and regulations promulgated thereunder.<br>The proposing stockholder must also comply with the requirements of applicable law, including Rule 14a-19 promulgated under the Exchange Act. | One or several shareholders holding at least 10% of the share capital in issue may request the addition of one or several items on the agenda of a general meeting.

#### SELLING SECURITYHOLDERS
This prospectus relates to the resale by the Selling Securityholders from time to time of up to 461,286,233 Ordinary Shares and 3,545,210 Warrants to purchase Ordinary Shares, which were originally Private Placement Warrants that were automatically converted into Warrants upon consummation of the Merger.

The Selling Securityholders may from time to time offer and sell any or all of the Ordinary Shares and Warrants set forth below pursuant to this prospectus and any accompanying prospectus supplement. When we refer to the "Selling Securityholders" in this prospectus, we mean the persons listed in the table below, and the pledgees, donees, transferees, assignees, successors, designees and others who later come to hold any of the Selling Securityholders' interest in the Ordinary Shares and Warrants other than through a public sale.

The table below sets forth, as of the date of this prospectus, the name of the Selling Securityholders for which we are registering Ordinary Shares and/or Warrants for resale to the public, the aggregate number of Ordinary Shares and/or Warrants beneficially owned and the aggregate principal amount that the Selling Securityholders may offer pursuant to this prospectus. The individuals and entities listed below have beneficial ownership over their respective securities. The SEC has defined "beneficial ownership" of a security to mean the possession, directly or indirectly, of voting power and/or investment power over such security. A shareholder is also deemed to be, as of any date, the beneficial owner of all securities that such shareholder has the right to acquire within 60 days after that date through (i) the exercise of any option, warrant or right, (ii) the conversion of a security, (iii) the power to revoke a trust, discretionary account or similar arrangement, or (iv) the automatic termination of a trust, discretionary account or similar arrangement. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares subject to options or other rights (as set forth above) held by that person that are currently exercisable, or will become exercisable within 60 days thereafter, are deemed outstanding, while such shares are not deemed outstanding for purposes of computing percentage ownership of any other person. 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.

For purposes of the "*Ordinary Shares*" table below, we have based percentage ownership on 597,699,586 Ordinary Shares and for purposes of the "*Warrants*" table below, we have based percentage ownership on 16,749,984 Warrants outstanding, as of the date of this prospectus, which became exercisable for Ordinary Shares on September 3, 2021.

We cannot advise you as to whether the Selling Securityholders will in fact sell any or all of such Ordinary Shares and Warrants. As such, we are unable to declare the number of Ordinary Shares and Warrants that the Selling Securityholders will retain after any such sale. In addition, the Selling Securityholders may sell, transfer or otherwise dispose of, at any time and from time to time, the Ordinary Shares and Warrants in transactions exempt from the registration requirements of the Securities Act after the date of this prospectus.

Selling Securityholder information for each additional Selling Securityholder, if any, will be set forth by prospectus supplement to the extent required prior to the time of any offer or sale of such Selling Securityholder's Ordinary Shares and/or Warrants pursuant to this prospectus. Any prospectus supplement may add, update, substitute, or change the information contained in this prospectus, including the identity of each Selling Securityholder and the number of Ordinary Shares and/or Warrants registered on its behalf. A Selling Securityholder may sell or otherwise transfer all, some or none of such Ordinary Shares or Warrants in this offering. See "*Plan of Distribution.*"

This includes Ordinary Shares owned by Mark Stone and Andrew McBride. Mark Stone and Andrew McBride were the former Chief Executive Officer and Chief Financial Officer of Gores Holdings V, Inc., respectively.

#### MATERIAL LUXEMBOURG TAX CONSIDERATIONS
The following is a general description of certain Luxembourg tax considerations relating to AMPSA and the holders of Ordinary Shares or Warrants. It does not purport to be a complete analysis of all tax considerations in relation to the Ordinary Shares or Warrants. Prospective purchasers should consult their own tax advisers as to which countries' tax laws could be relevant to acquiring, holding and disposing of the securities and the consequences of such actions under the tax laws of those countries. This overview is based upon the law as in effect on the date of this document and is subject to any change in law that may take effect after such date, even with retroactive effect.

The comments below are intended as a basic overview of certain tax consequences in relation to AMPSA and the purchase, ownership and disposition of Ordinary Shares or Warrants under Luxembourg Law. Tax matters are complex, and the tax consequences of the offering to a particular holder of Ordinary Shares or Warrants will depend in part on such holder's circumstances. Accordingly, a holder is urged to consult his or her own tax advisor for a full understanding of the tax consequences of the offering to him or her, including the applicability and effect of Luxembourg tax laws.

The summary in this Luxembourg taxation section does not address the Luxembourg tax consequences for a holder of Ordinary Shares or Warrants who:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) is an investor as defined in a specific law (such as the law on family wealth management companies of 11 May 2007, as amended, the law on undertakings for collective investment of 17 December 2010, as amended, the law on specialized investment funds of 13 February 2007, as amended, the law on reserved alternative investment funds of 23 July 2016, the law on securitisation of 22 March 2004, as amended, the law on venture capital vehicles of 15 June 2004, as amended and the law on pension saving companies and associations of 13 July 2005;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) is a Luxembourg resident individual;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) is, in whole or in part, exempt from tax; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) acquires, owns or disposes of Ordinary Shares or Warrants in connection with a membership of a management board, a supervisory board, an employment relationship, a deemed employment relationship or management role.

Where in this summary English terms and expressions are used to refer to Luxembourg tax concepts, the meaning to be attributed to such terms and expressions shall be the meaning to be attributed to the equivalent Luxembourg concepts under Luxembourg Law.

#### Taxation of AMPSA
AMPSA is subject to Luxembourg tax on its worldwide profits at the current combined ordinary rate of 23.87% for Luxembourg City, including (i) the 16% corporate income tax on which a 7% solidarity surcharge is added and (ii) a 6.75% municipal business tax (together the "Income Tax").

In principle, dividends and capital gains realized by AMPSA are subject to Income Tax in Luxembourg. However, provided the conditions of the Luxembourg participation exemption regime are met, dividends and capital gains realized by AMPSA upon the disposal of Shares are not taxable in Luxembourg. The Luxembourg participation exemption does not apply to the extent of previously deducted expenses, write-offs, and/or realized losses relating to the relevant participation i.e., those are recaptured. Certain general, as well as specific, anti-abuse provisions may also apply.

Luxembourg net wealth tax ("NWT") will be due annually by AMPSA at the rate of 0.5% on its total net asset value below or equal to €500 million. The tranche above €500 million will be taxed at a rate of 0.05%.

Shareholdings qualifying for the Luxembourg participation exemption regime are excluded from the NWT basis provided that, the relevant entity holds a direct shareholding in a qualifying subsidiary representing at least 10% of the

------

[**Table of Contents**](#TOC)

qualifying subsidiary's share capital or having an acquisition cost (including both share capital and share premium) of at least €1.2 million; there is no minimum holding period requirement.

AMPSA may be subject to progressive minimum NWT which ranges between €535 and €4,815 depending on the company's total amount of balance sheet.

#### Withholding taxation
Any dividends distributed by AMPSA will in principle be subject to a 15% withholding tax unless an exemption or a treaty reduction applies.

The concept "dividends distributed by AMPSA" as used in this Luxembourg taxation paragraph includes, but is not limited to, distributions in cash or in kind, proceeds paid by AMPSA upon a redemption or repurchase of Ordinary Shares and repayments of capital.

#### Luxembourg taxation of the holders
*Luxembourg tax residence of the holders*

Holders will not be deemed to be resident, domiciled or carrying on business in Luxembourg for income tax purposes solely by reason of holding, execution, performance, delivery, exchange and/or enforcement of the Ordinary Shares or Warrants.

*Taxation of Luxembourg non-residents*

Holders who are non-residents of Luxembourg and who do not have a permanent establishment, a permanent representative, or a fixed place of business in Luxembourg with which the holding of the Ordinary Shares or Warrants is connected, are not liable to any Luxembourg income tax (other than a tax potentially levied by way of withholding at source), whether they receive payments upon redemption or repurchase of all Ordinary Shares or Warrants, or realize capital gains on the sale of any Ordinary Shares or Warrants, unless they sell a substantial participation within 6 months of its acquisition or they have been a resident of Luxembourg for tax purposes for at least 15 years and have become a non-resident within the 5 years preceding the realization of the gain.

A participation is deemed to be substantial where a holder holds or has held, either alone or together with the holder's spouse or partner and/or minor children, directly or indirectly at any time within the five years preceding the disposal, more than 10% of the capital of AMPSA.

*Taxation of Luxembourg residents*

Holders who are Luxembourg resident companies (*société de capitaux*) or foreign entities which have a permanent establishment or a permanent representative in Luxembourg with which the holding of the Ordinary Shares or Warrants is connected, must include in their taxable income any income (including dividends) and the difference between the sale or redemption price and the tax book value of the Ordinary Shares or Warrants sold or redeemed, unless for Ordinary Shares the conditions of the Luxembourg participation exemption regime are met.

*Net Wealth Tax*

Luxembourg NWT will not be levied on the Ordinary Shares or Warrants held by a corporate holder, unless: (a) such holder is a Luxembourg resident or (b) such Ordinary Shares or Warrants are attributable to an enterprise or part thereof which is carried on by a non-resident company in Luxembourg through a permanent establishment. Ordinary Shares qualifying for the Luxembourg participation exemption regime are excluded from the NWT basis.

------

[**Table of Contents**](#TOC)

*Other Taxes*

No registration tax will be payable by a holder of Ordinary Shares or Warrants upon the disposal of Ordinary Shares or Warrants by sale or exchange. The issuance as well as the redemption of shares by a Luxembourg resident company as well as any other changes to its articles of association are subject to a fixed registration tax in Luxembourg amounting to €75. Registration duties may, moreover, be due if documents relating to the Ordinary Shares or Warrants are (i) voluntarily registered in Luxembourg, (ii) appended to a document that requires obligatory registration in Luxembourg or (iii) deposited with the official records of a Luxembourg notary.

There is no Luxembourg value added tax payable in respect of payments in consideration for the issuance of the Ordinary Shares or Warrants or in respect of the payment under the Ordinary Shares or Warrants or in respect of the transfer of the Ordinary Shares and/or Warrants.

No Luxembourg inheritance tax is levied on the transfer of the Ordinary Shares or Warrants upon the death of a holder in cases where the deceased was not a resident of Luxembourg for inheritance tax purposes. Where a holder is a resident or a deemed resident of Luxembourg for at the time of his or her death, the Ordinary Shares or Warrants are included in his taxable estate for inheritance tax assessment purposes. No Luxembourg gift tax will be levied on the transfer of the Ordinary Shares or Warrants by way of gift unless the gift is registered in Luxembourg.

#### MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS
This section describes the material U.S. federal income tax considerations to beneficial owners relating to the acquisition, ownership and disposition of the Ordinary Shares and Warrants ("AMPSA Securities"). This discussion applies only to Ordinary Shares and Warrants held as capital assets for U.S. federal income tax purposes (generally, property held for investment) and does not discuss all aspects of U.S. federal income taxation that might be relevant to holders in light of their particular circumstances or status, including the Medicare contribution tax on net investment income, or holders who are subject to special rules, including:

● brokers or dealers;

● traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

● tax-exempt organizations, qualified retirement plans, individual retirement accounts or other tax deferred accounts;

● banks or other financial institutions, underwriters, insurance companies, real estate investment trusts or regulated investment companies;

● U.S. expatriates or former long-term residents of the United States;

● persons that own (directly, indirectly, or by attribution) 5% or more (by vote or value) of the Ordinary Shares;

● persons holding AMPSA Securities as part of a straddle, hedging or conversion transaction, constructive sale, or other arrangement involving more than one position;

● U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

● persons that received AMPSA Securities as compensation for services; or

● controlled foreign corporations or passive foreign investment companies.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds AMPSA Securities, the tax treatment of a partner in such partnership will depend upon the status of the partner and the activities of the partnership. Partners and partnerships should consult their tax advisors regarding the U.S. federal income tax treatment of holding the AMPSA Securities.

This discussion is based on the Code, its legislative history, existing and proposed Treasury regulations promulgated under the Code (the "Treasury Regulations"), published guidance by the Internal Revenue Service (the "IRS") and court decisions, all as of the date hereof. These laws are subject to change, possibly on a retroactive basis. This discussion is necessarily general and does not address all aspects of U.S. federal income taxation, including the effect of the U.S. federal alternative minimum tax, or U.S. federal estate and gift tax, or any state, local or non-U.S. tax laws to a holder of AMPSA Securities. AMPSA has not sought and does not intend to seek any rulings from the IRS regarding the AMPSA Securities. There is no assurance that the IRS will not take positions concerning the tax consequences of holding the AMPSA Securities that are different from those discussed below, or that any such different positions would not be sustained by a court.

**THE DISCUSSION BELOW IS A GENERAL SUMMARY. IT IS NOT A SUBSTITUTE FOR TAX ADVICE. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE IMPORTANT TO YOU. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE, LOCAL, NON-U.S. AND OTHER TAX CONSEQUENCES TO THEM OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE AMPSA SECURITIES.**

------

[**Table of Contents**](#TOC)

#### U.S. Holders
The section applies to you if you are a U.S. holder. For purposes of this discussion, a U.S. holder means a beneficial owner of AMPSA Securities that is, for U.S. federal income tax purposes:

● an individual who is a citizen or resident of the United States;

● a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

● an estate whose income is subject to U.S. federal income tax regardless of its source; or

● a trust if (1) a U.S. court can exercise primary supervision over the trust's administration and one or more U.S. persons are authorized to control all substantial decisions of the trust; or (2) the trust has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

*Distributions on Ordinary Shares*

Subject to the discussion below under "— *Passive Foreign Investment Company Rules*," the gross amount of any distribution on Ordinary Shares generally will be taxable to a U.S. holder as ordinary dividend income on the date such distribution is actually or constructively received, but only to the extent that the distribution is paid out of AMPSA's current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because AMPSA does not maintain, nor is it required to maintain, calculations of its earnings and profits under U.S. federal income tax principles, it is expected that any distributions generally will be reported to U.S. holders as dividends. Any such dividends generally will not be eligible for the dividends received deduction allowed to corporations in respect of dividends received from other U.S. corporations.

With respect to non-corporate U.S. holders, dividends will be taxed at the lower applicable long-term capital gains rate (see "— *Sale, Exchange, Redemption or Other Taxable Disposition of Ordinary Shares and Warrants*" below) if Ordinary Shares are readily tradable on an established securities market in the United States (which they will be if Ordinary Shares are traded on the NYSE) and certain other requirements are met, including that AMPSA is not classified as a passive foreign investment company during the taxable year in which the dividend is paid or the preceding taxable year. There can be no assurance that Ordinary Shares will be considered readily tradable on an established securities market in a given year. U.S. holders should consult their own tax advisors regarding the potential availability of the lower rate for any dividends paid with respect to Ordinary Shares.

As discussed in the section of this registration statement captioned "*Material Luxembourg Tax Considerations*", withholding taxes may be imposed under Luxembourg Law upon dividends paid by AMPSA. Subject to certain conditions and limitations, withholding taxes on dividends paid by AMPSA may be treated as foreign taxes eligible for credit or deduction against a U.S. holder's U.S. federal income tax liability under the U.S. foreign tax credit rules. For purposes of calculating the U.S. foreign tax credit, dividends paid on Ordinary Shares will generally be treated as income from sources outside the United States and will generally constitute passive category income. Treasury Regulations impose additional requirements that must be met for a foreign tax to be creditable, but IRS notices provide temporary relief from certain of these requirements until the date that a notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). The rules governing the U.S. foreign tax credit are complex.

U.S. holders should consult their tax advisors regarding the availability of the U.S. foreign tax credit or deduction under their particular circumstances.

*Sale, Exchange, Redemption or Other Taxable Disposition of Ordinary Shares and Warrants*

Subject to the discussion below under "— *Passive Foreign Investment Company Rules*," a U.S. holder generally will recognize gain or loss on any sale, exchange, redemption or other taxable disposition of AMPSA Securities in an

------

[**Table of Contents**](#TOC)

amount equal to the difference between (i) the amount realized on the disposition and (ii) such U.S. holder's adjusted tax basis in such securities. Any gain or loss recognized by a U.S. holder on a taxable disposition of AMPSA Securities generally will be capital gain or loss and will be long-term capital gain or loss if the holder's holding period in such Ordinary Shares or Warrants exceeds one year at the time of the disposition. Preferential tax rates may apply to long-term capital gains of non-corporate U.S. holders (including individuals). The deductibility of capital losses is subject to limitations. Any gain or loss recognized by a U.S. holder on the sale or exchange of AMPSA Securities generally will be treated as U.S. source gain or loss.

*Exercise or Lapse of a Warrant*

Subject to the PFIC rules discussed below and except as discussed below with respect to the cashless exercise of a Warrant, a U.S. holder generally will not recognize gain or loss upon the exercise of a Warrant for cash. A U.S. holder's tax basis in an Ordinary Share received upon exercise of the Warrant generally should be an amount equal to the sum of (i) the U.S. holder's tax basis in the Warrant exchanged therefor and (ii) the exercise price. The U.S. holder's holding period for an Ordinary Share received upon exercise of the Warrant will begin on the date following the date of exercise (or possibly the date of exercise) of the Warrant and will not include the period during which the U.S. holder held the Warrant. If a Warrant is allowed to lapse unexercised, a U.S. holder generally will recognize a capital loss equal to such holder's tax basis in the Warrant.

The tax consequences of a cashless exercise of a Warrant are not clear under current U.S. federal income tax law. A cashless exercise may be tax-deferred, either because the exercise is not a realization event or because the exercise is treated as a recapitalization for U.S. federal income tax purposes. In either tax- deferred situation, a U.S. holder's basis in the Ordinary Shares received would equal the holder's basis in the Warrants exercised therefor. If the cashless exercise were treated as not being a realization event, it is unclear whether a U.S. holder's holding period for the Ordinary Shares would be treated as commencing on the date of exercise of the Warrants or the day following the date of exercise of the Warrants. If the cashless exercise were treated as a recapitalization, the holding period of the Ordinary Shares would include the holding period of the Warrants exercised therefor.

It is also possible that a cashless exercise of a Warrant could be treated in part as a taxable exchange in which gain or loss would be recognized. In such event, a U.S. holder would recognize gain or loss with respect to the portion of the exercised Warrants treated as surrendered to pay the exercise price of the Warrants (the "surrendered warrants"). The U.S. holder would recognize capital gain or loss with respect to the surrendered warrants in an amount generally equal to the difference between (i) the fair market value of the Warrants deemed surrendered and (ii) the U.S. holder's tax basis in the surrendered warrants. In this case, a U.S. holder's tax basis in the Ordinary Shares received would equal the U.S. holder's tax basis in the Warrants exercised (meaning, the Warrants disposed of by the U.S. holder in the cashless exercise, other than the surrendered warrants) and the exercise price of such Warrants. It is unclear whether a U.S. holder's holding period for the Ordinary Shares would commence on the date of exercise of the Warrants or the day following the date of exercise of the Warrants.

Due to the absence of authority on the U.S. federal income tax treatment of a cashless exercise of warrants, there can be no assurance which, if any, of the alternative tax consequences and holding periods described above would be adopted by the IRS or a court of law. Accordingly, U.S. holders should consult their tax advisors regarding the tax consequences of a cashless exercise of Warrants.

*Possible Constructive Distributions*

The terms of each Warrant provide for an adjustment to the number of Ordinary Shares for which the Warrant may be exercised or to the exercise price of the Warrant in certain events, as discussed in the section of this registration statement captioned "*Description of Securities*." An adjustment which has the effect of preventing dilution generally is not taxable. A U.S. holder of a Warrant would, however, be treated as receiving a constructive distribution from AMPSA if, for example, the adjustment increases the holder's proportionate interest in AMPSA's assets or earnings and profits (e.g., through an increase in the number of Ordinary Shares that would be obtained upon exercise of such Warrant) as a result of a distribution of cash to the holders of the Ordinary Shares which is taxable to the U.S. holders of such shares as described under "— *Distributions on Ordinary Shares*" above. Such constructive distribution would be subject to tax as

------

[**Table of Contents**](#TOC)

described under that section in the same manner as if the U.S. holder of such Warrant received a cash distribution from AMPSA equal to the fair market value of such increased interest.

*Passive Foreign Investment Company Rules*

The treatment of U.S. holders of the AMPSA Securities could be materially different from that described above if AMPSA is treated as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes. A PFIC is any non-U.S. corporation with respect to which either: (i) 75% or more of the gross income for a taxable year constitutes passive income for purposes of the PFIC rules, or (ii) 50% or more of such non-U.S. corporation's assets in any taxable year (generally based on the quarterly average of the value of its assets during such year) is attributable to assets, including cash, that produce passive income or are held for the production of passive income. Passive income generally includes dividends, interest, royalties and certain rents. The determination of whether a non-U.S. corporation is a PFIC is based upon the composition of such non-U.S. corporation's income and assets (including, among others, its proportionate share of the income and assets of any other corporation in which it owns, directly or indirectly, 25% or more (by value) of the stock), and the nature of such non-U.S. corporation's activities. A separate determination must be made after the close of each taxable year as to whether a non-U.S. corporation was a PFIC for that year. Once a non-U.S. corporation qualifies as a PFIC it is, with respect to a shareholder during the time it qualifies as a PFIC, and subject to certain exceptions, always treated as a PFIC with respect to such shareholder, regardless of whether it satisfied either of the qualification tests in subsequent years.

Based on the composition of AMPSA's income and assets (including the income and assets of each subsidiary for which AMPSA owns, directly or indirectly, 25% or more (by value) of its stock), AMPSA does not expect to be classified as a PFIC for its current taxable year or for any taxable year in the foreseeable future. However, the application of the PFIC rules is subject to uncertainty as the composition of AMPSA's income and assets (including the income and assets of its applicable subsidiaries) may change in the future and, therefore, no assurances can be provided that AMPSA will not be a PFIC for the current taxable year or in a future year.

If AMPSA is or becomes a PFIC during any year in which a U.S. holder holds AMPSA Securities and such holder does not make a mark-to-market election, as described below, the U.S. holder will be subject to special tax rules with respect to (i) any gain realized on a sale or other disposition (including a pledge) of its AMPSA Securities, and (ii) any "excess distributions" it receives on its Ordinary Shares (generally, any distributions in excess of 125% of the average of the annual distributions on Ordinary Shares during the preceding three years or the U.S. holder's holding period, whichever is shorter). Generally, under this excess distribution regime:

● the gain or excess distribution will be allocated ratably over the period during which the U.S. holder held its AMPSA Securities;

● the amount allocated to the current taxable year will be treated as ordinary income; and

● the amount allocated to prior taxable years will be subject to the highest tax rate in effect for that taxable year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

In lieu of being subject to the special tax rules discussed above with regard to its Ordinary Shares, a U.S. holder may make a mark-to-market election with respect to its Ordinary Shares. A U.S. holder may make a mark-to-market election if such shares are treated as "marketable stock." The Ordinary Shares generally will be treated as marketable stock if they are regularly traded on a national securities exchange that is registered with the SEC, including the NYSE, or on a qualified non-U.S. exchange or other market (within the meaning of the applicable Treasury Regulations). Although the Ordinary Shares are listed on the NYSE, no assurance can be given that the Ordinary Shares will be "regularly traded" for purposes of the mark-to-market election. AMPSA does not intend to provide information necessary for U.S. holders to make a "qualified electing fund" election which, if available, would result in tax treatment different from the general tax treatment for PFICs described above.

------

[**Table of Contents**](#TOC)

If AMPSA is classified as a PFIC for any taxable year, a U.S. holder of Ordinary Shares will be required to file an annual report on IRS Form 8621. Failure to file IRS Form 8621 for each applicable taxable year may result in substantial penalties and result in the U.S. holder's taxable years being open to audit by the IRS until such forms are properly filed.

U.S. holders are urged to consult their tax advisors concerning the U.S. federal income tax consequences of holding AMPSA Securities in the event that AMPSA is considered a PFIC in any taxable year.

*Additional Reporting Requirements*

U.S. holders who are individuals and certain entities will be required to report information with respect to such U.S. holder's investment in "specified foreign financial assets" on IRS Form 8938 (Statement of Specified Foreign Financial Assets), subject to certain exceptions (including an exception for AMPSA Securities held in accounts maintained at certain financial institutions). An interest in AMPSA Securities constitutes a specified foreign financial asset for these purposes. Persons who are required to report specified foreign financial assets and fail to do so may be subject to substantial penalties and the period of limitations on assessment and collection of U.S. federal income taxes will be extended in the event of a failure to comply. U.S. holders are urged to consult their tax advisors regarding the foreign financial asset and other reporting obligations and their application to the ownership and disposition of AMPSA Securities.

#### Non-U.S. Holders
The section applies to you if you are a non-U.S. holder. For purposes of this discussion, a "non-U.S. holder" is a beneficial owner (other than a partnership or an entity or arrangement characterized as a partnership for U.S. federal income tax purposes) of AMPSA Securities that is not a U.S. holder, including a nonresident alien individual (other than certain former citizens and residents of the United States), a non-U.S. corporation, or a non-U.S. estate or trust.

This section generally does not apply to an individual who is present in the United States for 183 days or more in a taxable year. A holder that is such an individual should consult its tax advisor regarding the U.S. federal income tax consequences of holding AMPSA Securities.

*Non-U.S. Holders Generally*

Since AMPSA is not a U.S. corporation, a non-U.S. holder of Ordinary Shares should not be subject to U.S. federal income tax or, subject to the discussion below under "— *Information Reporting and Backup Withholding*," U.S. federal withholding tax on any dividends (including constructive dividends) received on AMPSA Securities or any gain recognized on a sale or other disposition of AMPSA Securities (including, any distribution to the extent it exceeds the adjusted basis in the non-U.S. holder's Ordinary Shares) unless such dividend or gain (i) is effectively connected with the non-U.S. holder's conduct of a trade or business in the United States, and (ii) if required by an applicable tax treaty, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States.

Any such dividends and gains that are effectively connected with a non-U.S. holder's conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base in the United States) generally will be subject to U.S. federal income tax at the same regular U.S. federal income tax rates applicable to a comparable U.S. holder and, in the case of a corporate non-U.S. holder, also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

The U.S. federal income tax treatment of a non-U.S. holder's exercise of a Warrant, or the lapse of a Warrant held by a non-U.S. holder, generally will correspond to the U.S. federal income tax treatment of the exercise or lapse of a Warrant held by a U.S. holder, as described under "— *U.S. Holders — Exercise or Lapse of a Warrant*," above, although to the extent a cashless exercise results in a taxable exchange, the consequences for a non-U.S. holder of recognizing gain in such a taxable exchange would be the same as the consequences of recognizing gain on a sale or other disposition of AMPSA Securities described in the preceding paragraphs above regarding a non-U.S. holder's sale or other disposition of AMPSA Securities.

------

[**Table of Contents**](#TOC)

#### Information Reporting and Backup Withholding
Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries are subject to information reporting, and may be subject to backup withholding. Backup withholding generally will not apply, however, to a U.S. holder if (i) the U.S. holder is an exempt recipient or (ii) in the case of backup withholding, the U.S. holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. A non-U.S. holder generally will eliminate the requirement for information reporting and backup withholding by providing certification of its non-U.S. status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a holder will be allowed as a credit against such holder's U.S. federal income tax liability and a holder may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for a refund with the IRS and furnishing any required information.

#### PLAN OF DISTRIBUTION
We are registering the issuance by us of 16,749,984 Ordinary Shares that may be issued upon the exercise of the Warrants at an exercise price of $11.50 per share, subject to adjustments. We are also registering the resale by the Selling Securityholders from time to time of up to 461,286,233 Ordinary Shares and 3,545,210 Warrants to purchase Ordinary Shares, which were originally Private Placement Warrants that were automatically converted into Warrants upon consummation of the Merger.

We will receive up to an aggregate of $192,624,816 if all the Warrants are exercised to the extent such Warrants are exercised for cash. All of the Ordinary Shares and Warrants offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective amounts. We will not receive any of the proceeds from these sales.

#### Primary Offering
Pursuant to the terms of the Warrants, the Ordinary Shares will be distributed to those holders who surrender the Warrants and provide payment of the exercise price to us. Upon receipt of proper notice by any of the holders of the Warrants issued that such holder desires to exercise a Warrant, we will, within the time allotted by the agreement governing Warrants, issue the holder Ordinary Shares and issue instructions to our transfer agent to mirror the issuance to the holder, free of a restrictive legend.

#### Resale by Selling Securityholders
The Selling Securityholders will pay any underwriting discounts, if applicable (it being understood that the Selling Securityholders shall not be deemed to be underwriters solely as a result of their participation in this offering), and commissions and expenses incurred by the Selling Securityholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholders in disposing of the securities. We will bear all other costs, fees and expenses incurred in effecting the registration of the securities covered by this prospectus, including, without limitation, all registration and filing fees, NYSE listing fees and fees and expenses of our counsel and our independent registered public accountants.

The securities beneficially owned by the Selling Securityholders covered by this prospectus may be offered and sold from time to time by the Selling Securityholders. The term "Selling Securityholders" includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from a Selling Securityholder as a gift, pledge, partnership distribution or other transfer. The Selling Securityholders 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 Securityholder 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 Securityholders 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. If underwriters are used in the sale, such underwriters will acquire the shares and/or warrants for their own account. 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 securities may be offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase the securities will be subject to certain conditions. The underwriters will be obligated to purchase all the securities offered if any of the securities are purchased.

Subject to the limitations set forth in any applicable registration rights agreement, the Selling Securityholders may use any one or more of the following methods when selling the securities offered by this prospectus:

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

------

[**Table of Contents**](#TOC)

● ordinary brokerage transactions and transactions in which the broker solicits purchasers;

● block trades in which the broker-dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

● an over-the-counter distribution in accordance with the rules of the NYSE;

● through trading plans entered into by a Selling Securityholder pursuant to Rule 10b5-1 under the Exchange Act that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

● through one or more underwritten offerings on a firm commitment or best efforts basis;

● settlement of short sales entered into after the date of this prospectus;

● agreements with broker-dealers to sell a specified number of the securities at a stipulated price per share and/or warrant;

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

● on an exchange or other similar offerings through sales agents;

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

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

● through a combination of any of the above methods of sale; or

● any other method permitted pursuant to applicable law.

In addition, a Selling Securityholder that is an entity may in certain circumstances elect to make a pro rata in-kind distribution of securities to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. In appropriate circumstances, such members, partners or stockholders may thereby receive freely tradeable securities. To the extent a distributee is an affiliate of ours (or in other circumstances where prospectus delivery continues to be required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

There can be no assurance that the Selling Securityholders will sell all or any of the securities offered by this prospectus. In addition, the Selling Securityholders may also sell securities under Rule 144 under the Securities Act, if available, or in other transactions exempt from registration, rather than under this prospectus. The Selling Securityholders 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.

The Selling Securityholders also may transfer the securities in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus. Upon being notified by a Selling Securityholder that a donee, pledgee, transferee, other successor- in-interest intends to sell our securities, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a selling securityholder.

[**Table of Contents**](#TOC)

With respect to a particular offering of the securities held by the Selling Securityholders, 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:

● the specific securities to be offered and sold;

● the names of the selling securityholders;

● the respective purchase prices and public offering prices, the proceeds to be received from the sale, if any, and other material terms of the offering;

● settlement of short sales entered into after the date of this prospectus;

● the names of any participating agents, broker-dealers or underwriters; and

● any applicable commissions, discounts, concessions and other items constituting compensation from the selling securityholders.

In connection with distributions of the securities or otherwise, the Selling Securityholders 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 the securities in the course of hedging the positions they assume with Selling Securityholders. The Selling Securityholders may also sell the securities short and redeliver the securities to close out such short positions. The Selling Securityholders 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 securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The Selling Securityholders may also pledge securities 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 securities 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 Securityholders may solicit offers to purchase the securities directly from, and it 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 Ordinary Shares and Warrants are currently listed on the NYSE under the symbols "AMBP" and "AMBP.WS," respectively.

The Selling Securityholders 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 Securityholders pay for solicitation of these contracts.

A Selling Securityholder may enter into derivative 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 Securityholder or borrowed from any Selling Securityholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from any Selling Securityholder 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 Securityholder may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using 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 Securityholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Securityholders in amounts to be negotiated immediately prior to the sale.

In compliance with the guidelines of the Financial Industry Regulatory Authority ("FINRA"), the aggregate maximum discount, commission, fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the gross proceeds of any offering pursuant to this prospectus and any applicable prospectus supplement.

If at the time of any offering made under this prospectus a member of 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 Securityholders and any broker-dealer or agent regarding the sale of the securities by the Selling Securityholders. Upon our notification by a Selling Securityholder 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 securities covered by this prospectus, if any of the Selling Securityholders or any underwriters, broker-dealers or agents who execute sales for the Selling Securityholders are deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales, any discounts, commissions, concessions or profit they earn on any resale of those securities may be underwriting discounts and commissions under the Securities Act.

The underwriters, broker-dealers and agents may engage in transactions with us or the Selling Securityholders, or perform services for us or the Selling Securityholders, in the ordinary course of business.
