Our Company

We are a supplier of integrated technology platforms (ecosystem platforms) that enable customers to run their EV charging and energy business models on those decentralized platforms. Our ecosystem platforms consist of hardware, software and services and are designed to provide key functions such as flexibility (energy storage with a battery), intelligent energy- and data management, as well as a wide range of related and recurring digital and physical services. We believe that these decentralized ecosystem platforms will play a significant role in the transition to a low carbon economy. These decentralized systems are getting more and more complex as the level of integration increases. Development must follow continuous changes in regulatory requirements and component improvements. Batteries, power inverters and all the software and security involved must be serviceable and maintained over a long period of time. For the leading players in the future energy market such as utilities and operators, the question of which platforms to invest in and run their business on will, in our opinion, be based on the quality and total cost of ownership of such platforms. Our core business is providing and servicing these ecosystem platforms to, ideally, all of the future power companies, in principle, striving to reach a CO2 neutral world. Due to the depth of our experience and capabilities across a wide range of technical disciplines, we have positioned ourselves as partner of choice for customers running their business and serving their end-customers on these platforms. We strive to penetrate three main domains of the decentralized energy market: (1) Ultra-fast Charging on power limited grids; (2) Residential sector coupling; and (3) Commercial & Industrial applications.

Recent Developments

2023 PIPE

On December 22, 2023, we entered into a subscription agreement with Mirabella Financial Services LLP, acting solely in its capacity as alternative investment fund manager of Svelland (the “Subscription Agreement”) for the purchase and sale of an aggregate of 1,666,667 Ordinary Shares for $6.00 per share and warrants to purchase up to 1,339,285 Ordinary Shares. Each of the 714,285 Six-Month Warrants is currently exercisable at an exercise price of $7.00 per Ordinary Share and will expire 6 months from the date of issuance. Each of the 625,000 One-Year Warrants is currently exercisable at an exercise price of $8.00 per Ordinary Share and will expire one year from the date of issuance. The closing of the 2023 PIPE occurred on December 28, 2023.

The Subscription Agreement contains customary registration rights in respect of the securities issued in connection with the 2023 PIPE. Within 60 days following the execution of the Subscription Agreement (the “Filing Deadline”), we are required to file a registration statement to register for resale the Ordinary Shares and Warrants issued in the 2023 PIPE and our Ordinary Shares issuable upon exercise of the Warrants. We have also agreed to use our commercially reasonable efforts to have such registration statement declared effective under the Securities Act as soon as practicable after the filing thereof, but no later than the earlier of (i) the 30th calendar day (or the 60th calendar day if the SEC notifies us that it will review the registration statement) following the applicable Filing Deadline and (ii) the 10th business day after the date we are notified by the SEC that the registration statement will not be reviewed or will not be subject to further review.

Implications of Being an Emerging Growth Company and a Foreign Private Issuer

We qualify as an “emerging growth company” as defined in the JOBS Act. As an emerging growth company, we may take advantage of certain exemptions from specified disclosure and other requirements that are otherwise generally applicable to public companies. These exemptions include:

●

an exemption from the provisions of Section 404(b) of the Sarbanes-Oxley Act of 2002 requiring that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting;

●

reduced disclosure obligations regarding executive compensation; and

●

not being required to hold a nonbinding advisory vote on executive compensation or to seek shareholder approval of any golden parachute payments not previously approved.

We will remain an “emerging growth company” until the earliest to occur of (i) the last day of the fiscal year (a) following the fifth anniversary of the closing of the Business Combination, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of equity securities held by our non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

We are also considered a “foreign private issuer” subject to reporting requirements under the Exchange Act, as a non-U.S. company with foreign private issuer status. As a “foreign private issuer,” we will be subject to different U.S. securities laws than domestic U.S. issuers. The rules governing the information that we must disclose differ from those governing U.S. corporations pursuant to the Exchange Act. This means that, even after we no longer qualify as an emerging growth company, as long as we 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 rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders and requirements that the proxy statements conform to Schedule 14A of the proxy rules promulgated under the Exchange Act;

●

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 (i.e., officers, directors and holders of more than 10% of our issued and outstanding equity securities) 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;

●

the rules under the Exchange Act requiring the filing with the SEC of quarterly reports 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; and

●

the SEC rules on disclosure of compensation on an individual basis unless individual disclosure is required in our home country (Ireland) and is not otherwise publicly disclosed by us.

We may take advantage of these exemptions until such time as we are no longer a foreign private issuer.

We would cease to be a foreign private issuer at such time as more than 50% of our outstanding voting securities are held by U.S. residents and any of the following three circumstances applies: (i) the majority of our executive officers or directors are U.S. citizens or residents, (ii) more than 50% of our assets are located in the United States or (iii) our business is administered principally in the United States.

We may choose to take advantage of some but not all of these reduced reporting requirements of which we have taken advantage of in this prospectus. Accordingly, the information contained herein may be different from the information you receive from our competitors that are U.S. domestic filers or other U.S. domestic public companies in which you have made an investment.

You should carefully consider these risk factors in addition to the other information included in this prospectus, including matters addressed in the section entitled “Forward-Looking Statements.” We may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial, which may also impair our business or financial condition. The risk factors should be read in conjunction with our financial statements and notes to the financial statements incorporated by reference herein. 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 prices of our securities could decline and you could lose part or all of your investment.

This prospectus contains or may contain forward-looking statements as defined in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”) that involve significant risks and uncertainties.

These forward-looking statements include information about our possible or assumed future results of operations or our performance. These statements involve known and unknown risks, uncertainties and other factors, including those listed under “Risk Factors,” and elsewhere in this prospectus that may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

In some cases, these forward-looking statements can be identified by words and phrases such as “may,” “should,” “intend,” “predict,” “potential,” “continue,” “will,” “expect,” “anticipate,” “estimate,” “plan,” “believe,” “is /are likely to” or the negative form of these words and phrases or other comparable expressions.

Other sections of this prospectus include additional factors which could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risk factors and uncertainties emerge from time to time and it is not possible for our management to predict all risk factors and uncertainties, nor can we assess the impact of all factors 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.

You should not rely upon forward-looking statements as predictions of future events.

We will receive up to an aggregate of approximately $10.0 million from the exercise of the Warrants, assuming the exercise in full of all of the Warrants. We expect to use the net proceeds from the exercise of the Warrants to continue to fund the development and operations of the Company and for general corporate purposes, which may include payment of the Company’s suppliers and working capital uses.

We have not paid any cash dividends on our ordinary shares to date. Our board of directors will consider whether or not to institute a dividend policy. It is presently intended that we will retain our earnings for use in business operations and, accordingly, it is not anticipated that our board of directors will declare dividends in the foreseeable future.

We are a public limited company organized and existing under the laws of Ireland. We were formed on 26 July 2021 as a public limited company under the name ADS-TEC ENERGY PLC. Our affairs are governed by our M&A, the Irish Companies Act and the corporate law of Ireland. Our authorized share capital is (a) US $60,000 divided into (i) 500,000,000 Ordinary Shares, with a nominal value of $0.0001 per share, and (ii) 100,000,000 preferred shares, with a nominal value of $0.0001 per share and (b) €25,000 divided into 25,000 deferred ordinary shares with a nominal value of €1.00 per share, which are held by ADSE Holdco as treasury shares.

General. As of January 16, 2024, there were 50,584,758 Ordinary Shares issued and outstanding. In addition, ADSE Holdco holds €25,000 worth of deferred ordinary shares in ADSE Holdco as treasury shares.

Dividends. The holders of Ordinary Shares are entitled to such dividends as may be declared by our board of directors. Dividends may be declared and paid out of the funds legally available therefor. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Irish Companies Act.

Voting Rights. Each Ordinary Share shall be entitled to one vote on all matters subject to the vote at general meetings of the Company. Voting at any meeting of shareholders is by way of a poll, which shall be taken in such manner as the chairperson of the meeting directs.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the Ordinary Shares cast at a meeting, while a special resolution requires the affirmative vote of no less than 75% of the votes cast attaching to the outstanding ordinary shares at a meeting. Where the shareholders wish to act by way of written resolution in lieu of holding a meeting, unanimous consent of the holders of the Ordinary Shares shall be required. A special resolution will be required for important matters such as a change of name, reducing the share capital or making changes to the M&A to be in effect.

Transfer of Ordinary Shares. Subject to the restrictions contained in the Business Combination Agreement with respect to the ADSE Holdco securities issued to the ADSE GM Shareholders in the Share-for-Share Exchange, the provisions of the Lock-Up Agreement, and subject to any further restrictions contained in the M&A, any ADSE Holdco shareholder may transfer all or any of his or her Ordinary Shares by an instrument of transfer in the usual or common form or any other form approved by ADSE Holdco’s board of directors from time to time.

Liquidation. On a return of capital on winding-up or otherwise (other than on conversion, redemption or purchase of ordinary shares), assets available for distribution among the holders of Ordinary Shares shall be distributed among the holders thereof on a pro rata basis. If ADSE Holdco’s assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that, as nearly as may be, the losses are borne by ADSE Holdco’s shareholders proportionately.

General Meetings of Shareholders. Shareholders’ meetings may be convened by the board of directors, by the board of directors on the requisition of the shareholders or, if the board of directors fails to so convene a meeting, such extraordinary general meeting may be convened by the requisitioning shareholders where the requisitioning shareholders hold not less than 10% of the paid up share capital of ADSE Holdco. Any action required or permitted to be taken at any annual or extraordinary general meetings may be taken only upon the vote of the shareholders at an annual or extraordinary general meeting duly noticed and convened in accordance with the M&A and the Irish Companies Act. Unanimous consent of the holders of the Ordinary Shares shall be required before the shareholders may act by way of written resolution without a meeting.

General. As of January 16, 2024, there were an aggregate of 11,662,486 Business Combination Warrants issued and outstanding. Certain “private warrants”, being warrants initially issued by EUSG to EUSG Sponsor and the Underwriters rather than those issued to the public, (i) will not be redeemable by ADSE Holdco, (ii) may be exercised for cash or on a cashless basis at the holder’s option as long as such warrants are held by the initial holders or their affiliates or permitted transferees, and (iii) were subject to a lockup for a period of 30 days from the closing of the Transactions.

Exercisability. Each Business Combination Warrant entitles the registered holder to purchase one Ordinary Share.

The exercise price and number of Ordinary Shares issuable on exercise of the Business Combination Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, the Business Combination Warrants will not be adjusted for issuances of Ordinary Shares at a price below the Business Combination Warrant exercise price.

Exercise Period. The Business Combination Warrants are exercisable at any time and from time to time until 5:00 p.m., New York City time on December 22, 2026, or earlier upon their redemption.

No Business Combination Warrants will be exercisable for cash unless ADSE Holdco has an effective and current registration statement covering the offer and sale of the Ordinary Shares issuable upon exercise of the Business Combination Warrants and a current prospectus relating to such Ordinary Shares. Notwithstanding the foregoing, if a registration statement covering the offer and sale of Ordinary Shares issuable upon exercise of the Business Combination Warrants is not effective within a specified period following the consummation of the Transactions, warrant holders may, until such time as there is an effective registration statement and during any period when ADSE Holdco shall have failed to maintain an effective registration statement, exercise Business Combination Warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their Business Combination Warrants on a cashless basis. In such event, each holder would pay the exercise price by surrendering the Business Combination Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Business Combination Warrants, multiplied by the difference between the exercise price of the Business Combination Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the Ordinary Shares for the five trading days ending on the trading day prior to the date of exercise.

ADSE Holdco has agreed to use its best efforts to file and have an effective registration statement covering the offer and sale of the Ordinary Shares issuable upon exercise of the Business Combination Warrants, to maintain a current prospectus relating to those Ordinary Shares until the earlier of the date the Business Combination Warrants expire or are redeemed and the date on which all of the Business Combination Warrants have been exercised, and to qualify the resale of such shares under U.S. state blue sky laws, to the extent an exemption is not available. However, there is no assurance that ADSE Holdco will be able to do so and, if ADSE Holdco does not maintain a current prospectus relating to the offer and sale of the Ordinary Shares issuable upon exercise of the Business Combination Warrants, holders will be unable to exercise their Business Combination Warrants for cash and ADSE Holdco will not be required to net cash settle or cash settle the Business Combination Warrant exercise.

Redemption of Business Combination Warrants. ADSE Holdco may call the Business Combination Warrants for redemption (excluding certain Business Combination Warrants initially issued to EUSG’s initial shareholders, so long as such Business Combination Warrants are held by the EUSG initial shareholders or their respective affiliates and certain permitted transferees), in whole and not in part, at a price of $0.01 per Business Combination Warrant:

The right to exercise will be forfeited unless the Business Combination Warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a Business Combination Warrant will have no further rights except to receive the redemption price for such holder’s Business Combination Warrant upon surrender of such Business Combination Warrant.

The redemption criteria for the Business Combination Warrants have been established at a price which is intended to provide Business Combination Warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then-prevailing share price and the Business Combination Warrant exercise price so that if the share price declines as a result of the redemption call, the redemption will not cause the share price to drop below the exercise price of the Business Combination Warrants.

If ADSE Holdco calls the Business Combination Warrants for redemption as described above, ADSE Holdco’s management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the Business Combination Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Business Combination Warrants, multiplied by the difference between the exercise price of the Business Combination Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the Ordinary Shares for the five trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Business Combination Warrants.

Registered Form. The Business Combination Warrants will be held in registered form pursuant to the Amended and Restated Warrant Agreement among ADSE Holdco, EUSG, and Continental Stock Transfer & Trust Company, as warrant agent. The Amended and Restated Warrant Agreement provides that the terms of the Business Combination Warrants may be amended without the consent of any holder to cure any ambiguity or correct or supplement any defective provision, but requires the approval, by written consent or vote, of the holders of at least a majority of the then outstanding Business Combination Warrants in order to make any change that adversely affects the interests of the registered holders.

Manner of Exercise. The Business Combination Warrants may be exercised upon surrender of the holder’s Business Combination Warrant certificate on or prior to the expiration date at the offices or agency of the warrant agent, with the exercise form on the reverse side of the Business Combination Warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to ADSE Holdco or by wire transfer, for the number of Business Combination Warrants being exercised.

Business Combination Warrant holders may elect to be subject to a restriction on the exercise of their Business Combination Warrants such that an electing Business Combination Warrant holders would not be able to exercise their Business Combination Warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the Ordinary Shares outstanding.

No Rights as a Shareholder. The Business Combination Warrant holders have neither the rights nor the privileges of holders of Ordinary Shares, nor do they have any voting rights until they exercise their Business Combination Warrants and receive Ordinary Shares. After the issuance of Ordinary Shares upon exercise of the Business Combination Warrants, each holder will be entitled to one vote for each Ordinary Share held of record on all matters to be voted on by holders of Ordinary Shares.

No Fractional Shares. No fractional shares will be issued upon exercise of the Business Combination Warrants. If, upon exercise of the Business Combination Warrants, a holder would be entitled to receive a fractional interest in a share, ADSE Holdco will, upon exercise, round up to the nearest whole number the number of Ordinary Shares to be issued to the warrant holder.

General. The following description of the Warrants issued in connection with the 2023 PIPE is qualified in its entirety by reference to the full text of the Six-Month Warrant Agreement (“Six-Month Warrant Agreement”) and One-Year Warrant Agreement (“One-Year Warrant Agreement”) by and between the Company and Mirabella Financial Services LLP, dated as of December 28, 2023 (including the form of warrant attached thereto, the “Warrant Agreement”), which is attached to the registration statement of which this prospectus forms a part as Exhibit 4.1.

Exercisability. Each Warrant entitles the registered holder to purchase one Ordinary Share.

Exercise Price. 714,285 of the Warrants are exercisable at an exercise price of $7.00 per Ordinary Share (“Six-Month Warrants”). 625,000 of the Warrants are exercisable at an exercise price of $8.00 per Ordinary Share (“One-Year Warrants”).

Exercise Period. The Six-Month Warrants are exercisable at any time and from time to time until 5:00 p.m., Eastern Time on June 28, 2024. The One-Year Warrants are exercisable at any time and from time to time until 5:00 p.m., Eastern Time on December 28, 2024.

No Rights as a Shareholder. The Warrant holder has neither the rights nor the privileges of holders of Ordinary Shares, nor does it have any voting rights until it exercises its Warrants and receive Ordinary Shares. After the issuance of Ordinary Shares upon exercise of the Warrants, the holder will be entitled to one vote for each Ordinary Share held of record on all matters to be voted on by holders of Ordinary Shares.

No Fractional Shares. No fractional shares will be issued upon exercise of the Warrants. If, upon exercise of the Warrants, a holder would be entitled to receive a fractional interest in a share, ADSE Holdco will, upon exercise, pay the holder an amount in cash in lieu of a fractional share.

ADSE Holdco’s transfer agent and warrant agent is Continental Stock Transfer & Trust Company. ADSE Holdco’s registrar is Link Group.

Our Ordinary Shares and the Business Combination Warrants are listed on Nasdaq under the symbols “ADSE” and “ADSEW,” respectively. Holders of our securities should obtain current market quotations for their securities. There can be no assurance that our Ordinary Shares will remain listed on Nasdaq. If we fail to comply with the Nasdaq listing requirements, our Ordinary Shares and/or warrants could be delisted from Nasdaq. A delisting of our Ordinary Shares and warrants will likely affect the liquidity of our Ordinary Shares and warrants and could inhibit or restrict our ability to raise additional financing.

There is no trading market available for the Warrants on any securities exchange or nationally recognized trading system. We do not intend to list the Warrants on Nasdaq or any securities exchange or nationally recognized trading system.

This prospectus and any supplement hereto relate to the possible offer and sale from time to time of up to 3,005,952 Ordinary Shares (including the Ordinary Shares issuable upon exercise of the Warrants) and the Warrants to purchase up to 1,339,285 Ordinary Shares by the selling securityholder. The selling securityholder acquired the securities offered hereby in the 2023 PIPE. See “Prospectus Summary — Recent Developments — 2023 PIPE.”

The selling securityholder may from time to time offer and sell any or all of the Ordinary Shares (including the Ordinary Shares issuable upon exercise of the Warrants) and the Warrants set forth below pursuant to this prospectus. When we refer to the “selling securityholder” in this prospectus, we mean Svelland and the pledgees, donees, transferees, assignees, successors and others who later come to hold any of the selling securityholder’s interest in our securities after the date of this prospectus.

The following table is prepared based on information provided to us by the selling securityholder. It sets forth the name and address of the selling securityholder, the aggregate number of Ordinary Shares (including the Ordinary Shares issuable upon exercise of the Warrants) and Warrants that the selling securityholder may offer pursuant to this prospectus and the beneficial ownership of the selling securityholder both before and after the offering. We have based percentage ownership on 50,584,758 Ordinary Shares outstanding as of January 16, 2024. In calculating the denominator used to determine percentages of Ordinary Shares owned after the offering described herein is consummated by the selling securityholder, we did not give effect to the exercise of any other outstanding warrants issued by the Company that may be held by the selling securityholder.

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 securityholder is also deemed to be, as of any date, the beneficial owner of all securities that such securityholder 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, ordinary 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 of January 16, 2024, are deemed outstanding, while such shares are not deemed outstanding for purposes of computing percentage ownership of any other person.

We cannot advise you as to whether the selling securityholder will in fact sell any or all of such Ordinary Shares (including the Ordinary Shares issuable upon exercise of the Warrants) or the Warrants. In addition, the selling securityholder may sell, transfer or otherwise dispose of, at any time and from time to time, and without our prior consent, the Ordinary Shares (or the Ordinary Shares issuable upon exercise of the Warrants) or the Warrants (as applicable) in transactions exempt from the registration requirements of the Securities Act after the date of this prospectus, subject to applicable law.

Relevant information for each additional selling securityholder, if any, will be set forth in a prospectus supplement to the extent required prior to the time of any offer or sale of a selling securityholder’s securities 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 or Warrants registered on its behalf. The selling securityholder may sell all, some or none of such securities in this offering. See “Plan of Distribution.”

References in this “Taxation” section to “Warrants” refer only to the Warrants sold in the 2023 PIPE and not to any of the Company’s other outstanding warrants.

The following discussion is a general summary of certain material U.S. federal income tax considerations to U.S. Holders (as defined below) of the acquisition, ownership and disposition of Ordinary Shares and Warrants. The information set forth in this section is based on the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, final, temporary and proposed U.S. Treasury regulations promulgated thereunder (“Treasury Regulations”), published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”) and court decisions, all as in effect as of the date hereof. These authorities are subject to change or differing interpretations, possibly on a retroactive basis, in a manner that could adversely affect the tax considerations discussed below.

For purposes of this summary, a “U.S. Holder” means a beneficial owner of Ordinary Shares or Warrants that is for U.S. federal income tax purposes:

This discussion does not address all aspects of U.S. federal income taxation that may be relevant to any particular U.S. Holder based on such U.S. Holder’s individual circumstances. In particular, this discussion considers only U.S. Holders that hold Ordinary Shares or Warrants as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address the alternative minimum tax, the Medicare tax on net investment income or the U.S. federal income tax consequences to holders that are subject to special rules, including, without limitation:

This discussion does not address any tax laws other than the U.S. federal income tax law, such as U.S. federal gift or estate tax laws, state, local or non-U.S. tax laws.

If a partnership (or other entity or arrangement classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of Ordinary Shares or Warrants, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. A holder that is a partnership and the partners in such partnership should consult their tax advisors with regard to the U.S. federal income tax consequences of the acquisition, ownership and disposition of Ordinary Shares and Warrants.

No ruling has been requested or will be obtained from the IRS regarding the U.S. federal income tax consequences of acquiring, owning or disposing Ordinary Shares or Warrants or any other related matter or other matter discussed herein. There can be no assurance that the IRS will not challenge the U.S. federal income tax treatment described below or that, if challenged, such treatment will be sustained by a court.

EACH HOLDER OF ORDINARY SHARES OR WARRANTS SHOULD CONSULT ITS TAX ADVISORS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDERS OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF ORDINARY SHARES AND WARRANTS, INCLUDING THE EFFECTS OF U.S. FEDERAL, STATE, AND LOCAL AND NON-U.S. TAX LAWS.

Subject to the PFIC rules discussed in the section below titled “— Passive Foreign Investment Company Status,” if ADSE Holdco makes a distribution of cash or other property to a U.S. Holder of Ordinary Shares, such distribution generally will be treated as a dividend for U.S. federal income tax purposes to the extent the distribution is paid out of ADSE Holdco’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of such earnings and profits generally will be applied against and reduce (but not below zero) a U.S. Holder’s basis in its Ordinary Shares, and any remaining excess will be treated as gain from the sale or exchange of such Ordinary Shares (see “— Sale, Exchange, Redemption or Other Taxable Disposition of Ordinary Shares or Warrants” below).

With respect to corporate U.S. Holders, dividends with respect to Ordinary Shares generally will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations. With respect to non-corporate U.S. Holders, ADSE Holdco dividends generally will be taxed as “qualified dividend income” at preferential long-term capital gains rates if (i) Ordinary Shares are readily tradable on an established securities market in the United States or ADSE Holdco is eligible for the benefits of an approved qualifying income tax treaty with the United States that includes an exchange of information program, (ii) certain holding period and at-risk requirements are met, (iii) ADSE Holdco is not treated as a PFIC in the taxable year in which the dividend is paid or the preceding taxable year, and (iv) certain other requirements are met. U.S. Holders should consult their tax advisors regarding the availability of the preferential rate for any dividends paid with respect to Ordinary Shares.

Subject to certain conditions and limitations, withholding taxes, if any, on dividends paid by ADSE Holdco may be treated as foreign taxes eligible for credit 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 non-U.S. source income and will generally constitute passive category income. 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 under particular circumstances.

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

Subject to the PFIC rules discussed in the section below titled “— Passive Foreign Investment Company Status,” upon a sale, exchange, redemption or other taxable disposition of Ordinary Shares or Warrants, a U.S. Holder will generally recognize capital gain or loss. The amount of gain or loss recognized generally will be equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such sale, exchange, redemption or other taxable disposition, and (ii) such U.S. Holder’s adjusted tax basis in the Ordinary Shares or Warrants sold.

Capital gain or loss will generally constitute long-term capital gain or loss if a U.S. Holder’s holding period for the Ordinary Shares or Warrants exceeds one year. Long-term capital gains recognized by non-corporate U.S. Holders may be taxable at preferential rates. The deductibility of capital losses is subject to limitations. For purposes of calculating the U.S. foreign tax credit, gain or loss recognized by a U.S. Holder upon the sale, exchange, redemption or other taxable disposition of Ordinary Shares or Warrants will generally be treated as U.S. source gain or loss. 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 under particular circumstances.

Subject to the PFIC rules discussed in the section below titled “— Passive Foreign Investment Company Status,” a U.S. Holder generally will not recognize gain or loss upon the acquisition of an Ordinary Warrant on the exercise of a Warrant for cash. It is unclear whether a U.S. Holder’s holding period for the Ordinary Shares will commence on the date of exercise of the Warrant or the day following the date of exercise of the Warrant; in either case, the holding period 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.

Cash received in lieu of a fractional Ordinary Share should be treated as a payment in exchange for such fractional Ordinary Share resulting in gain or loss in an amount equal to the difference between the amount of cash received and such U.S. Holder’s tax basis in the fractional Ordinary Share.

A failure to adjust the number of Ordinary Shares for which a Warrant may be exercised or to the exercise price of a Warrant in certain events could be treated as a constructive distribution from ADSE Holdco if the failure to adjust were to be considered to increase the U.S. Holder’s proportionate interest in ADSE Holdco’s assets or earnings and profits. Such constructive distribution generally should be subject to tax as described under “— Distributions on Ordinary Shares” above in the same manner as if the U.S. Holder of the Warrant had received a cash distribution from ADSE Holdco equal to the fair market value of the increase in the interest. The rules governing constructive distributions as a result of failing to make certain adjustments with respect to a Warrant are complex, and U.S. Holders are urged to consult their tax advisors on the tax consequences of any such constructive distribution with respect to a Warrant.

A non-U.S. corporation, such as ADSE Holdco, will be classified as a PFIC if either: (a) at least 75% of its gross income is “passive income” for purposes of the PFIC rules, or (b) at least 50% of the value of its gross assets (determined on the basis of a quarterly average) is attributable to assets that produce or are held for the production of passive income. Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions, and net gains from the disposition of assets which produce passive income. A corporation will be treated as owning a proportionate share of the assets and earning a proportionate share of the income of another corporation if the first-mentioned corporation owns, directly or indirectly, 25% or more (by value) of the stock of the other corporation.

It is uncertain whether ADSE Holdco will be treated as a PFIC for the current taxable year or any future taxable years. This is a factual determination that must be made annually at the close of each taxable year and depends, among other things, upon the composition of ADSE Holdco’s gross income and assets. Additionally, the value of ADSE Holdco’s assets for purposes of the PFIC determination will generally be determined by reference to its market capitalization, which is likely to fluctuate. Accordingly, there can be no assurance that ADSE Holdco will not be a PFIC for the current taxable year or in future taxable years.

If ADSE Holdco is determined to be a PFIC for any taxable year (or any portion thereof) that is included in the holding period of a U.S. Holder and, in the case of Ordinary Shares, such U.S. Holder did not make a timely and effective qualified electing fund (“QEF”) election or a mark-to-market election (each described below) for ADSE Holdco’s first taxable year as a PFIC in which such U.S. Holder held (or was deemed to hold) Ordinary Shares, then such U.S. Holder will generally be subject to special and adverse rules with respect to (i) any gain recognized by such U.S. Holder on the sale or other disposition of its Ordinary Shares or Warrants and (ii) any “excess distribution” made to a U.S. Holder (generally, any distributions to a U.S. Holder during a taxable year of such U.S. Holder that are greater than 125% of the average annual distributions received by such U.S. Holder in respect of Ordinary Shares during the three preceding taxable years of such U.S. Holder or, if shorter, such U.S. Holder’s holding period for such Ordinary Shares). Under these default PFIC rules:

In general, a U.S. Holder may avoid the adverse PFIC tax consequences described above in respect of the Ordinary Shares (but not the Warrants) by making and maintaining a timely and valid QEF election (if eligible to do so) to include in income its pro rata share of ADSE Holdco’s net capital gains (as long-term capital gain) and other earnings and profits (as ordinary income), on a current basis, in each case whether or not distributed, in the taxable year of the U.S. Holder in which or with which ADSE Holdco’s taxable year ends. In order to comply with the requirements of a QEF election, a U.S. Holder must receive certain information from ADSE Holdco. ADSE Holdco has not determined whether it will provide U.S. Holders with this information if it determines that it is a PFIC.

Alternatively, if ADSE Holdco is a PFIC and the Ordinary Shares are treated as “marketable stock,” a U.S. Holder may also be to avoid the adverse PFIC tax consequences described above if such U.S. Holder, at the close of the first taxable year in which it holds (or is deemed to hold) the Ordinary Shares, makes an election to mark such shares to their market value for such taxable year (a “mark-to-market election”). Such U.S. Holder generally will include as ordinary income for each year that ADSE Holdco is treated as a PFIC the excess, if any, of the fair market value of its Ordinary Shares at the end of its taxable year over such U.S. Holder’s adjusted basis in its Ordinary Shares. Such U.S. Holder also will be allowed to take an ordinary loss in respect of the excess, if any, of its adjusted basis of its Ordinary Shares over the fair market value of its Ordinary Shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). Such U.S. Holder’s basis in its Ordinary Shares will be adjusted to reflect any such income or loss recognized. Gain recognized on a sale or other taxable disposition of the Ordinary Shares in a taxable year in which ADSE Holdco is a PFIC will be treated as ordinary income, and any loss will be ordinary to the extent of the net amount of previously included income as a result of the mark-to-market election (and thereafter will be capital loss, the deductibility of which is subject to limitations). Currently, a mark-to-market election may not be made with respect to the Warrants.

The mark-to-market election is available for “marketable stock,” which generally is stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including NASDAQ, or on a foreign exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. U.S. Holders should consult their tax advisors regarding the availability and tax consequences of a mark-to-market election in their particular circumstances.

If ADSE Holdco is a PFIC and, at any time, any subsidiary is classified as a PFIC, U.S. Holders would generally be deemed to own a portion of the shares of such lower-tier PFIC, and generally could incur liability under the default PFIC rules described above if ADSE Holdco receives a distribution from, or disposes of all or part of ADSE Holdco’s interest in, the lower-tier PFIC or if such U.S. Holders otherwise are deemed to have disposed of an interest in the lower-tier PFIC. A mark-to-market election generally would not be available with respect to such lower-tier PFIC. U.S. Holders are urged to consult their tax advisors regarding the tax issues raised by lower-tier PFICs.

A U.S. Holder that owns (or is deemed to own) shares in a PFIC during any taxable year of such U.S. Holder may be required to file IRS Form 8621 with such U.S. Holder’s U.S. federal income tax return and provide such other information as may be required by the Treasury Regulations or other IRS guidance.

The rules dealing with PFICs are very complex and affected by various factors in addition to those described above. Accordingly, U.S. Holders should consult their tax advisors concerning the application of the PFIC rules to Ordinary Shares or Warrants under their particular circumstances.

Certain U.S. Holders are required to report information to the IRS relating to an interest in “specified foreign financial assets,” including shares issued by a non-U.S. corporation, for any year in which the aggregate value of all specified foreign financial assets exceeds an applicable threshold based on whether the U.S. Holder is an entity or an individual (and in the case of an individual, the threshold depends upon such individual’s filing status and whether the individual resides in the United States), subject to certain exceptions (including an exception for shares held in custodial accounts maintained with a U.S. financial institution). Generally, ADSE Holdco securities would constitute “specified foreign financial assets.” Penalties may apply if a U.S. Holder is required to submit such information to the IRS and fails to do so.

Distributions with respect to Ordinary Shares (including constructive distributions with respect to the Warrants) and proceeds from the sale, exchange, redemption or other taxable disposition of Ordinary Shares or the Warrants may be subject to information reporting to the IRS and possible U.S. backup withholding at a current rate of 24%. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification on IRS Form W-9 or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status generally must provide such certification on IRS Form W-9.

U.S. backup withholding is not an additional tax. Amounts withheld as U.S. backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability, and a U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules, if the required information is timely furnished to the IRS. Transactions effected through certain brokers or other intermediaries may be subject to U.S. backup withholding, and such brokers or intermediaries may be required by law to do U.S. backup withholding.

U.S. Holders are urged to consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Anticipated Material Irish Tax Consequences to Non-Irish Holders of ADSE Holdco Securities

The following is a summary of the anticipated material Irish tax consequences of the acquisition, ownership and disposal of Ordinary Shares and Warrants. The summary is based upon Irish tax laws and the practice of the Irish Revenue Commissioners in effect on the date of this prospectus and stamp duty and withholding tax clearances which have been granted by the Irish Revenue Commissioners. Changes in law and/or administrative practice may result in a change in the tax consequences described below, possibly with retrospective effect.

A “Non-Irish Holder” is an individual who beneficially owns their Ordinary Shares and/or Warrants, that is neither a resident nor ordinarily resident in Ireland for Irish tax purposes and does not hold their Ordinary Shares and/or Warrants, in connection with a trade carried on by such person through an Irish branch or agency.

This summary does not constitute tax advice and is intended only as a general guide. The summary is not exhaustive and securityholders should consult their tax advisors about the Irish tax consequences (and tax consequences under the laws of other relevant jurisdictions) of the acquisition, ownership and disposal of Ordinary Shares and Warrants. The summary applies only to Non-Irish Holders who hold their Ordinary Shares and/or Warrants, as capital assets and does not apply to other categories of Non-Irish Holders, such as dealers in securities, trustees, insurance companies, collective investment schemes and Non-Irish Holders who acquired, or are deemed to have acquired, their Ordinary Shares and/or Warrants by virtue of an Irish office or employment (performed or carried on to any extent in Ireland).

The summary does not, except where expressly stated, consider the position of Non-Irish Holders who hold their Ordinary Shares and/or Warrants directly (and not beneficially through a broker or custodian (through DTC)). The Irish tax consequences of transactions in Ordinary Shares and/or Warrants held directly are generally negative when compared with Ordinary Shares and/or Warrants held through DTC. Any Non-Irish Holder contemplating holding their Ordinary Shares and/or Warrants directly should consult their personal tax advisors as to the Irish tax consequences of acquiring, owning and disposing of such Ordinary Shares and/or Warrants.

The current rate of tax on chargeable gains (where applicable) in Ireland is 33%. Non-Irish Holders will not be within the territorial scope of a charge to Irish CGT on a disposal of their Ordinary Shares and/or Warrants, provided that such Ordinary Shares and/or Warrants neither (a) were used in or for the purposes of a trade carried on by such Non-Irish Holder through an Irish branch or agency, nor (b) were used, held or acquired for use by or for the purposes of an Irish branch or agency.

The rate of stamp duty (where applicable) on transfers of shares or warrants of Irish incorporated companies is 1% of the greater of the price paid or market value of the shares or warrants acquired. Where Irish stamp duty arises it is generally a liability of the transferee. However, in the case of a gift or transfer at less than fair market value, all parties to the transfer are jointly and severally liable.

Irish stamp duty may be payable in respect of transfers of Ordinary Shares and Warrants, depending on the manner in which the Ordinary Shares and Warrants are held. ADSE Holdco has entered into arrangements with DTC to allow the Ordinary Shares and Warrants to be settled through the facilities of DTC. As such, the discussion below discusses separately the securityholders who hold their shares through DTC and those who do not.

The Irish Revenue Commissioners have confirmed to ADSE Holdco that transfers of Ordinary Shares and Warrants effected by means of the transfer of book entry interests in DTC will not be subject to Irish stamp duty.

Ordinary Shares or Warrants Held Outside of DTC or Transferred Into or Out of DTC

A transfer of Ordinary Shares or Warrants where any party to the transfer holds such Ordinary Shares or Warrants outside of DTC may be subject to Irish stamp duty.

Holders of Ordinary Shares or Warrants wishing to transfer their Ordinary Shares or Warrants into (or out of) DTC may do so without giving rise to Irish stamp duty provided that:

Due to the potential Irish stamp charge on transfers of Ordinary Shares and Warrants held outside of DTC, it is strongly recommended that those securityholders who do not hold their ADSE Holdco securities through DTC (or through a broker who in turn holds such shares through DTC) should arrange for the transfer of their ADSE Holdco securities as into DTC as soon as possible.

Distributions made by ADSE Holdco will, in the absence of one of many exemptions, be subject to DWT, currently at a rate of 25%.

For DWT and Irish income tax purposes, a distribution includes any distribution that may be made by ADSE Holdco to holders of Ordinary Shares, including cash dividends, non-cash dividends and additional stock taken in lieu of a cash dividend. Where an exemption from DWT does not apply in respect of a distribution made to a holder of Ordinary Shares, ADSE Holdco is responsible for withholding DWT prior to making such distribution.

Irish domestic law provides that a non-Irish resident holder of Ordinary Shares is not subject to DWT on distributions received from ADSE Holdco if such holder of Ordinary Shares is beneficially entitled to the distribution and is either:

and provided, in all cases noted above (but subject to “Ordinary—Shares Held by U.S. Resident Shareholders” below), ADSE Holdco or, in respect of Ordinary Shares held through DTC, any qualifying intermediary appointed by ADSE Holdco, has received from the holder of such Ordinary Shares, where required, the relevant DWT Forms prior to the payment of the distribution. In practice, in order to ensure sufficient time to process the receipt of relevant DWT Forms, the holders of Ordinary Shares, where required, should furnish the relevant DWT Form to:

Links to the various DWT Forms are available at: http://www.revenue.ie/en/tax/dwt/forms/index.html. The information on such website does not constitute a part of, and is not incorporated by reference into, this prospectus.

For non-Irish resident holders of Ordinary Shares that cannot avail themselves of one of Ireland’s domestic law exemptions from DWT, it may be possible for such holder of Ordinary Shares to rely on the provisions of a double tax treaty to which Ireland is party to reduce the rate of DWT.

Distributions paid in respect of Ordinary Shares that are owned by a U.S. resident and held through DTC will not be subject to DWT provided the address of the beneficial owner of such Ordinary Shares in the records of the broker holding such Ordinary Shares is in the United States (and such broker has further transmitted the relevant information to a qualifying intermediary appointed by ADSE Holdco). It is strongly recommended that such holders of Ordinary Shares ensure that their information is properly recorded by their brokers (so that such brokers can further transmit the relevant information to a qualifying intermediary appointed by ADSE Holdco).

Distributions paid in respect of Ordinary Shares that are held outside of DTC and are owned by a resident of the United States will not be subject to DWT if such holder of Ordinary Shares provides a completed IRS Form 6166 or a valid DWT Form to ADSE Holdco’s transfer agent to confirm its U.S. residence and claim an exemption. It is strongly recommended that holders of Ordinary Shares (which are to be held outside of DTC) who are U.S. residents provide the appropriate completed IRS Form 6166 or DWT Form to ADSE Holdco’s transfer agent as soon as possible after receiving their Ordinary Shares.

Ordinary Shares Held by Residents of Relevant Territories Other Than the United States

Holders of Ordinary Shares who are residents of Relevant Territories, other than the United States, must satisfy the conditions of one of the exemptions referred to above under the heading “—General Exemptions”, including the requirement to furnish valid DWT Forms, in order to receive distributions without suffering DWT. If such holders of Ordinary Shares hold their Ordinary Shares through DTC, they must provide the appropriate DWT Forms to their brokers (so that such brokers can further transmit the relevant information to a qualifying intermediary appointed by ADSE Holdco) before the record date for the distribution (or such later date before the distribution payment date as may be notified to holder of Ordinary Shares by the broker). If such holders of Ordinary Shares hold their Ordinary Shares outside of DTC, they must provide the appropriate DWT Forms to ADSE Holdco’s transfer agent before the record date for the distribution. It is strongly recommended that such holders of Ordinary Shares complete the appropriate DWT Forms and provide them to their brokers or ADSE Holdco’s transfer agent, as the case may be, as soon as possible after receiving their Ordinary Shares.

If any holder of Ordinary Shares who is resident in a Relevant Territory receives a distribution from which DWT has been withheld, the holder of Ordinary Shares may be entitled to a refund of DWT from the Irish Revenue Commissioners provided the holder of Ordinary Shares is beneficially entitled to the distribution.

Holders of Ordinary Shares that do not fall within any of the categories specifically referred to above may nonetheless fall within other exemptions from DWT. If any holders of Ordinary Shares are exempt from DWT, but receive distributions subject to DWT, such holders of Ordinary Shares may apply for refunds of such DWT from the Irish Revenue Commissioners.

Distributions paid in respect of Ordinary Shares held through DTC that are owned by a partnership formed under the laws of a Relevant Territory and where all the underlying partners are resident in a Relevant Territory will be entitled to exemption from DWT if all of the partners complete the appropriate DWT Forms and provide them to their brokers (so that such brokers can further transmit the relevant information to a qualifying intermediary appointed by ADSE Holdco) before the record date for the distribution (or such later date before the distribution payment date as may be notified to the holder of Ordinary Shares by the broker). If any partner is not a resident of a Relevant Territory, no part of the partnership’s position is entitled to exemption from DWT.

Prior to paying any distribution, ADSE Holdco will put in place an agreement with an entity that is recognized by the Irish Revenue Commissioners as a “qualifying intermediary,” which will provide for certain arrangements relating to distributions in respect of Ordinary Shares that are held through DTC, which are referred to as the “Deposited Securities.” The agreement will provide that the qualifying intermediary shall distribute or otherwise make available to Cede & Co., as nominee for DTC, any cash dividend or other cash distribution with respect to the Deposited Securities after ADSE Holdco delivers or causes to be delivered to the qualifying intermediary the cash to be distributed.

ADSE Holdco will rely on information received directly or indirectly from its qualifying intermediary, brokers and its transfer agent in determining where holders of Ordinary Shares reside, whether they have provided the required U.S. tax information and whether they have provided the required DWT Forms. Holders of Ordinary Shares that are required to file DWT Forms in order to receive distributions free of DWT should note that such forms are generally valid, subject to a change in circumstances, until December 31 of the fifth year after the year in which such forms were completed.

Irish income tax may arise for certain persons in respect of distributions received from Irish resident companies.

A Non-Irish Holder that is entitled to an exemption from DWT will generally have no Irish income tax or universal social charge liability on a distribution from ADSE Holdco. A Non-Irish Holder that is not entitled to an exemption from DWT, and therefore is subject to DWT, generally will have no additional Irish income tax liability or liability to universal social charge. The DWT deducted by ADSE Holdco discharges the Irish income tax liability and liability to universal social charge.

CAT comprises principally gift tax and inheritance tax on property situated in Ireland for CAT purposes or otherwise within the territorial scope of CAT. CAT could apply to a gift or inheritance of Ordinary Shares and Warrants because Ordinary Shares and Warrants are regarded as property situated in Ireland for CAT purposes. The person who receives the gift or inheritance has primary liability for CAT.

CAT is currently levied at a rate of 33% on the value of any taxable gift or inheritance above certain tax-free thresholds. The appropriate tax-free threshold depends upon (1) the relationship between the donor and the donee and (2) the aggregation of the values of previous taxable gifts and inheritances received by the donee from persons within the same group threshold. Gifts and inheritances passing between spouses are exempt from CAT, as are gifts to certain charities. Children have a lifetime tax-free threshold of €335,000 in respect of taxable gifts or inheritances received from their parents. There is also a “small gift exemption” from CAT whereby the first €3,000 of the taxable value of all taxable gifts taken by a donee from any one donor, in each calendar year, is exempt from CAT and is also excluded from any future aggregation. This exemption does not apply to an inheritance.

THE IRISH TAX CONSIDERATIONS SUMMARIZED ABOVE ARE FOR GENERAL INFORMATION ONLY AND ARE NOT INTENDED TO PROVIDE ANY DEFINITIVE TAX REPRESENTATIONS TO HOLDERS. EACH SECURITYHOLDER SHOULD CONSULT HIS OR HER TAX ADVISOR AS TO THE PARTICULAR CONSEQUENCES THAT MAY APPLY TO SUCH SECURITYHOLDER.

We are registering the issuance by us of up to 1,339,285 Ordinary Shares issuable upon the exercise of the Warrants.

We are also registering the possible resale from time to time by the selling securityholder of, as applicable, (a) up to 3,005,952 Ordinary Shares (including 1,339,285 Ordinary Shares issuable upon exercise of the Warrants) and (b) Warrants to purchase 1,339,285 Ordinary Shares. We are also registering any additional securities that may become issuable by reason of share splits, share dividends or other similar transactions. All of the Ordinary Shares and Warrants offered by the selling securityholder pursuant to this prospectus will be sold by the selling securityholder for its own account. We will not receive any proceeds from the sale of the Ordinary Shares (including the Ordinary Shares issuable upon exercise of the Warrants) or the Warrants by the selling securityholder or the issuance of Ordinary Shares by us pursuant to this prospectus, except with respect to amounts received by us upon exercise of the Warrants. See “Use of Proceeds.”

The selling securityholder will pay any underwriting discounts and commissions and expenses incurred by the selling securityholder for brokerage, accounting, tax or legal services or any other expenses incurred by the selling securityholder 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, Nasdaq listing fees and fees and expenses of our counsel and our independent registered public accountants.

The securities beneficially owned by the selling securityholder covered by this prospectus may be offered and sold from time to time by the selling securityholder. The term “selling securityholder” includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from the selling securityholder as a gift, pledge, partnership distribution or other transfer. The selling securityholder 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 our then current market price or in negotiated transactions. The selling securityholder reserves the right to accept and, together with its agent, to reject, any proposed purchase of securities to be made directly or through its agent. The selling securityholder and any of its permitted transferees may sell its 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 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 the Subscription Agreement between the Company and Mirabella Financial Services LLP, the selling securityholder may use any one or more of the following methods when selling the securities offered by this prospectus:

In addition, the selling securityholder may elect to make a pro rata in-kind distribution of securities to its members, partners or shareholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus or prospectus supplement with a plan of distribution. Such members, partners or shareholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise 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 securityholder will sell all or any of the securities offered by this prospectus. In addition, the selling securityholder 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 securityholder has the sole and absolute discretion not to accept any purchase offer or make any sale of securities if it deems the purchase price to be unsatisfactory at any particular time.

The selling securityholder 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 the selling securityholder that a donee, pledgee, transferee or 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.

With respect to a particular offering of the securities held by the selling securityholder, 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:

In connection with distributions of the securities or otherwise, the selling securityholder 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 the selling securityholder. The selling securityholder may also sell the securities short and redeliver the securities to close out such short positions. The selling securityholder may also enter into option or other transactions with broker-dealers or other financial institutions that 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 securityholder 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 securityholder 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.

The selling securityholder 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 pay or the selling securityholder pays for solicitation of these contracts.

The 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 the selling securityholder or borrowed from the selling securityholder or others to settle those sales or to close out any related open borrowings of stock and may use securities received from the 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, the 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 securityholder may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling securityholder in amounts to be negotiated immediately prior to the sale.

To our knowledge, there are currently no plans, arrangements or understandings between the selling securityholder and any broker-dealer or agent regarding the sale of the securities by the selling securityholder. Upon our notification by the 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.

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.

Pursuant to the Subscription Agreement, we have agreed to indemnify the selling securityholder against certain liabilities, including certain liabilities under the Securities Act, the Exchange Act or other federal or state law.

We have agreed pursuant to the Subscription Agreement to use commercially reasonable efforts to keep the registration statement of which this prospectus constitutes a part effective with respect to the selling securityholder until the earliest of the following: (i) the selling securityholder ceases to hold any securities covered by this prospectus, (ii) the date all securities covered by this prospectus held by the selling securityholder may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for us to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (iii) two years from the effective date of this prospectus.

Set forth below is an itemization of the total expenses that are expected to be incurred by us in connection with the securities being registered hereby and the offer and sale of the Ordinary Shares (including the Ordinary Shares issuable upon exercise of the Warrants) and the Warrants by the selling securityholder. With the exception of the SEC registration fee, all amounts are estimates.

The validity of the Ordinary Shares to be offered by this prospectus, including the Ordinary Shares issuable upon the exercise of Warrants, and certain legal matters relating to Irish law have been passed upon by Arthur Cox, LLP, Dublin, Ireland. The validity of the Warrants to be offered by this prospectus and certain legal matters relating to New York have been passed upon by Reed Smith LLP, New York, New York. Any underwriters or agents will be advised about other issues relating to the offering by counsel to be named in the applicable prospectus supplement.

The consolidated financial statements of ADSE as of December 31, 2022 and 2021 and for each of the three years in the period ended December 31, 2022 incorporated by reference in this Prospectus and in the Registration Statement have been so included in reliance on the report of BDO AG Wirtschaftsprüfungsgesellschaft, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting. The report on the consolidated financial statements contains an explanatory paragraph regarding the Company’s ability to continue as a going concern.

We have filed with the SEC a registration statement (including exhibits to the registration statement) on Form F-3 under the Securities Act. This prospectus, which is part of the registration statement, does not contain all of the information set forth in the registration statement and the exhibits and schedules to the registration statement. For further information, we refer you to the registration statement and the exhibits and schedules filed as part of the registration statement. If a document has been filed as an exhibit to the registration statement, we refer you to the copy of the document that has been filed. Each statement in this prospectus relating to a document filed as an exhibit is qualified in all respects by the filed exhibit. We are subject to the informational requirements of the Exchange Act that are applicable to foreign private issuers. Accordingly, we are required to file or furnish reports and other information with the SEC, including annual reports on Form 20-F and reports on Form 6-K. The SEC maintains an Internet website that contains reports and other information regarding issuers that file electronically with the SEC. Our filings with the SEC are available to the public through the SEC’s website at http://www.sec.gov. As a foreign private issuer, we are exempt under the Exchange Act from, among other things, the rules prescribing the furnishing and content of proxy statements, and our executive officers, directors and principal and selling shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we will not be required under the Exchange Act to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. We maintain a corporate website at https://adstec-energy.com/. Information contained on, or that can be accessed through, our website does not constitute a part of this prospectus. We have included our website address in this prospectus solely for informational purposes.

The SEC allows the Company to “incorporate by reference” into this prospectus the information we file with or furnish to the SEC, which means that the Company can disclose important information to you by referring you to those documents. The Company hereby incorporates by reference in this prospectus the documents listed below and all amendments or supplements we may file to such documents:

All documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act and, to the extent specifically designated therein, Form 6-K’s, in each case, after the date of the initial registration statement of which this prospectus is a part and prior to the effectiveness of the registration statement, as well as prior to the completion or termination of the offering of securities under this prospectus, shall be deemed to be incorporated by reference in this prospectus and to be a part hereof from the date of filing or furnishing of such documents.

Any statement contained herein or in a document, all or a portion of which is incorporated or deemed to be incorporated by reference herein, shall be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement.
