Rhea-AI Filing Summary

ADS-TEC Energy PLC has filed a shelf registration on Form F-3 covering the potential resale, from time to time, of up to 27,493,949 Ordinary Shares by existing selling securityholders. The registration consists of 6,324,000 May 8 Subscription Shares, 3,000,000 May 28 Subscription Shares and 18,169,949 Other Shares acquired in a December 2023 private placement and subsequent open-market purchases.

All shares are being offered for the selling securityholders’ own account; the company will not receive any proceeds from these resales. ADS-TEC Energy previously received approximately $6.3 million and $3.0 million from the May 8 and May 28, 2026 subscription right exercises at $1.00 per share, respectively. Ordinary Shares trade on Nasdaq under the symbol “ADSE,” and there were 75,129,730 Ordinary Shares outstanding as of July 20, 2026.

The company develops battery-based energy infrastructure, including battery-buffered ultra-fast EV charging and energy storage systems, and is expanding toward operating infrastructure assets and large-scale storage projects. ADS-TEC Energy is an emerging growth company and a foreign private issuer, benefiting from reduced U.S. reporting requirements.

Filing Explained

The filing adds resale capacity for already-issued shares, but no sale is reported and the company receives no resale proceeds.

On July 21, 2026, ADS-TEC Energy filed an F-3 resale registration covering up to 27,493,949 ordinary shares; it is subject to completion, and the filing says the shares cannot be sold until the registration statement is effective. This creates resale capacity for existing holders rather than reporting a completed sale.

The shares are already described as issued or previously acquired: 6,324,000 subscription shares from May and 3,000,000 from June 2026 and 18,169,949 other shares from a December 2023 private placement and later open-market purchases. Selling holders receive any resale proceeds; the company will receive none.

The selling-holder table reports Mirabella Financial Services LLP offering 21,169,949 shares, UFI CAPITAL AS offering 4,000,000 shares, and Lucerne Capital Management LP offering 2,117,000 shares while retaining 15,062,341 shares under the table's assumption that all offered shares are sold.

The immediate resolution point is effectiveness of the F-3; any specific sale size, price, or selling arrangement would be set out in a later prospectus supplement or other applicable filing.

shelf registration process regulatory
"This prospectus is part of a registration statement on Form F-3 that we filed... using a “shelf” registration process."
emerging growth company regulatory
"We qualify as an “emerging growth company” as defined in the JOBS Act."
An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.
foreign private issuer regulatory
"We are also considered a “foreign private issuer” subject to reporting requirements under the Exchange Act."
A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.
Passive Foreign Investment Company financial
"Subject to the PFIC rules discussed in the section below titled “— Passive Foreign Investment Company Status,”"
A passive foreign investment company (PFIC) is a foreign corporation that, under U.S. tax rules, earns mostly passive income (like dividends, interest, rents, or royalties) or holds mostly passive assets. For U.S. investors, owning stock in a PFIC can trigger special, often punitive tax treatment and extra reporting requirements, which can raise the investor’s tax bill and reduce after‑tax returns—think of an unexpected tax surcharge that changes the real payoff of the investment.
Dividend Withholding Tax financial
"Withholding Tax on Dividends (DWT) Distributions made by the Company will... be subject to DWT, currently at a rate of 25%."
A dividend withholding tax is a government charge taken directly from dividend payments before they reach shareholders, so investors receive a smaller net payout. It matters because it reduces the cash investors actually get and can affect after-tax returns; depending on where the investor lives and tax treaties, some or all of the withheld amount may be claimed back or credited against other taxes, so careful record-keeping influences the final investment outcome.
Registration Rights Agreement regulatory
"the Company entered into a registration rights agreement with certain investors dated May 28, 2026 (the “Registration Rights Agreement”)"
A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.
Offering Type secondary
Use of Proceeds All proceeds from any sale of registered shares will go to the selling securityholders; the company has already received approximately $6.3 million and $3 million from the May 8 and May 28, 2026 subscription exercises.

Our Company

 

We develop and provide battery-based energy infrastructure solutions designed to support the electrification of mobility and the increasing integration of renewable energy sources. Our core activities include battery-buffered ultra-fast charging solutions and battery energy storage systems, with more than 2,500 charge points delivered and over 2.5 GWh of installed storage capacity through May 2026, complemented by software platforms, lifecycle services and, increasingly, infrastructure-related activities, including the operation of energy assets and the development of large-scale storage projects.

 

Our product and service offering comprises the sale of battery-buffered charging systems and battery energy storage systems for commercial, industrial and infrastructure applications, which are typically sold to customers under hardware sales contracts on a project or multi-site rollout basis. These hardware solutions are complemented by digital energy management platforms and lifecycle services, including monitoring, maintenance and service agreements, which support system performance over time and contribute to recurring revenue streams. In addition, we have begun expanding our business model to include Own & Operate activities, under which we participate more directly in the operation of infrastructure assets and related revenue streams, including charging, energy trading and other energy-related services. We are also engaged in the development of large-scale battery storage projects, including a unique project with a planned capacity of approximately 1 GW and up to 4 GWh, and this expansion reflects a broader shift from a primarily hardware-driven model toward a more diversified business model with a growing focus on recurring revenues.

 

Our solutions are designed to address the structural constraints of existing energy infrastructure, particularly the mismatch between available grid capacity and increasing, time-sensitive power demand. The Company’s platform enables electricity to be stored locally and delivered at high power independently of immediate grid availability, while also allowing energy flows to be monitored, controlled and optimized over time. To support this functionality, ADSE develops key elements of its systems in-house, including battery systems, control architecture and digital management software, which are integrated into a combined hardware and software solution. This integrated approach enables the deployment and operation of scalable charging and storage infrastructure across a range of applications, including both customer-owned systems and infrastructure projects operated by the Company, and supports the generation of multiple value streams from energy usage and management.

 

May 2026 Capital Structure Simplification

 

In connection with the simplification of ADSE Holdco’s capital structure, on May 8, 2026, the Company entered into subscription agreements (the “May 8 Subscription Agreements”) with certain investors, pursuant to which the Company agreed to issue non-transferable subscription rights to purchase up to an aggregate of 6,324,000 Ordinary Shares at an exercise price of $1.00 per Ordinary Share (such Ordinary Shares, the “May 8 Subscription Shares”). Pursuant to the May 8 Subscription Agreements, the investors exercised their right on May 8, 2026, to subscribe for 6,324,000 Ordinary Shares which were delivered to such investors on May 8, 2026.

Additionally, on May 28, 2026, the Company entered into a subscription agreement (the “ May 28 Subscription Agreement” and collectively with the May 8 Subscription Agreements, the “Subscription Agreements”) with certain investors, pursuant to which the Company agreed to issue non-transferable subscription rights to purchase up to an aggregate of 5,000,000 Ordinary Shares at an exercise price of $1.00 per Ordinary Share (such Ordinary Shares, the “May 28 Subscription Shares”) in exchange for support in connection with the Company’s efforts to simplify its capital structure. Pursuant to the Subscription Agreements, Svelland Global Trading Master Fund and certain accounts managed, or advised by, Mirabella Financial Services LLP exercised their right on May 28, 2026 to subscribe for 3,000,000 Subscription Shares, which were delivered to investors on June 5, 2026.

 

In connection with the Subscription Agreements, the Company entered into a registration rights agreement with certain investors dated May 28, 2026 (the “Registration Rights Agreement”), pursuant to which the Company agreed to provide customary resale shelf registration rights with respect to the Subscription Shares held by such investors.

 

This summary of certain terms and provisions of the Subscription Agreements and the Registration Rights Agreement is not complete and is subject to, and qualified in its entirety by, the provisions of each of the forms of Subscription Agreement and Registration Rights Agreement which were filed with the SEC as exhibits to the Current Reports on Form 6-K filed on May 12, 2026 and May 29, 2026, respectively.

 

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. Accordingly, we expect that we will no longer be an “emerging growth company” on December 31, 2026, which is the end of the fifth fiscal year following the Business Combination.

 

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 are 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;

 

2

 

 

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 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.

FORWARD-LOOKING STATEMENTS

 

This prospectus contains certain “forward-looking statements” as defined in Section 27A of the Securities Act and Section 21E of the Exchange Act that involve significant risks and uncertainties. All statements other than statements of historical facts are forward-looking statements. These forward-looking statements include information about our possible or assumed future results of operations or our performance. Words such as “expects,” “intends,” “plans,” “believes,” “anticipates,” “estimates,” and variations of such words and similar expressions are intended to identify the forward-looking statements.

 

The risk factors and cautionary language referred to or incorporated by reference in this prospectus provide examples of risks, uncertainties and events that may cause actual results to differ materially from the expectations described in our forward-looking statements, including, but not limited to, those items identified below.

 

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus. Although we believe that the expectations reflected in such forward-looking statements are reasonable, there can be no assurance that such expectations will prove to be correct. These statements involve known and unknown risks and are based upon a number of assumptions and estimates which are inherently subject to significant uncertainties and contingencies, many of which are beyond our control. Actual results may differ materially from those expressed or implied by such forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements contained in this prospectus, or the documents to which we refer readers in this prospectus, to reflect any change in our expectations with respect to such statements or any change in events, conditions or circumstances upon which any statement is based.

DIVIDEND POLICY

 

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.

SELLING SECURITYHOLDERS

 

This prospectus and any supplement hereto relate to the possible offer and sale from time to time of up to 27,493,949 Ordinary Shares, consisting of (i) 6,324,000 Ordinary Shares issued pursuant to the May 8 Subscription Agreements to the selling securityholders, (ii) 3,000,000 Ordinary Shares issued pursuant to the May 28 Subscription Agreement to the selling securityholders and (iii) 18,169,949 of our Other Shares. The selling securityholders acquired the Subscription Shares offered hereby in the May 2026 Capital Structure Simplification. The Other Shares were acquired by Svelland Global Trading Master Fund and certain other accounts managed, or advised by, Mirabella Financial Services LLP pursuant to a private placement transaction in December 2023 and certain open-market transactions between December 2023 and the date hereof. See “Prospectus Summary - May 2026 Capital Structure Simplification” for more information on the Subscription Shares.

 

The selling securityholders may from time to time offer and sell any or all of the Ordinary Shares covered by this prospectus as set forth below pursuant to this prospectus. When we refer to the “selling securityholders” in this prospectus, we mean the selling securityholders named under this section “Selling Securityholders” 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 securityholders. It sets forth the name and address of the selling securityholders, the aggregate number of Ordinary Shares that the selling securityholders may offer pursuant to this prospectus and the beneficial ownership of the selling securityholders both before and after the offering. We have based percentage ownership on 75,129,730 Ordinary Shares outstanding as of July 20, 2026. In calculating the denominator used to determine percentages of Ordinary Shares owned after the offering described herein is consummated by the selling securityholders, we did not give effect to the exercise of any other outstanding warrants issued by the Company that may be held by the selling securityholders.

 

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 July 20, 2026, 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 securityholders will in fact sell any or all of such Ordinary Shares covered by this prospectus. In addition, the selling securityholders may sell, transfer or otherwise dispose of, at any time and from time to time, and without our prior consent, such Ordinary Shares in transactions exempt from the registration requirements of the Securities Act after the date of this prospectus, subject to applicable law.

The information in the following table has been provided to us by or on behalf of the selling securityholders and has not been independently verified by us. For purposes of this table, we have assumed that the selling securityholders will have sold all of the Ordinary Shares offered herein upon the completion of the offering. Each of the selling securityholders listed has sole voting and investment power with respect to the shares beneficially owned by the selling securityholders unless noted otherwise. Relevant information for each additional selling securityholders, 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 registered on its behalf. The selling securityholders may sell all, some or none of such securities in this offering. See “Plan of Distribution.”

TAXATION

 

Material U.S. Federal Income Tax Considerations

 

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 ownership and disposition of the Ordinary Shares pursuant to this offering. 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 that is for U.S. federal income tax purposes:

 

an individual citizen or resident of the United States;

 

a corporation (or other entity treated as a corporation) that is 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 includible in gross income for U.S. federal income tax purposes regardless of its source; or

 

a trust if (i) 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 (ii) it has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

 

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 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:

 

banks or certain other financial institutions or financial services entities;

 

brokers, dealers or traders in securities;

 

persons that are subject to the mark-to-market accounting rules under Section 475 of the Code;

 

tax-exempt entities;

 

governments or agencies or instrumentalities thereof;

 

tax-qualified retirement plans;

 

insurance companies;

 

regulated investment companies;

 

real estate investment trusts;

 

certain expatriates or former long-term residents of the United States;

 

11

 

 

persons that hold Ordinary Shares as part of a straddle, constructive sale, hedging, redemption or other risk reduction strategy or as part of a conversion transaction or other integrated transaction;

 

persons whose functional currency is not the U.S. dollar;

 

corporations that accumulate earnings to avoid U.S. federal income tax (and their shareholders);

 

S corporations, partnerships or entities or arrangements treated as partnerships or other pass-through entities for U.S. federal income tax purposes, or shareholders, partners or members of such S corporations, partnerships or other pass-through entities;

 

persons who actually or constructively own 5% (measured by vote or value) or more of Ordinary Shares; and

 

holders that are not U.S. Holders.

 

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, 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.

 

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

 

Distributions on Ordinary Shares

 

Subject to the PFIC rules discussed in the section below titled “— Passive Foreign Investment Company Status,” if the Company 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 the Company’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” 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, the Company 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 the Company 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) the Company 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. Our Ordinary Shares are listed on the Nasdaq and we accordingly expect the first condition described above to be satisfied. U.S. Holders should consult their tax advisors regarding the availability of the preferential rate for any dividends paid with respect to Ordinary Shares.

 

12

 

 

Subject to certain conditions and limitations, withholding taxes, if any, on dividends paid by the Company 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

 

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, 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 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 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 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.

 

Passive Foreign Investment Company Status

 

A non-U.S. corporation, such as the Company, 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.

 

The Company believes that it was not a PFIC in its most recent taxable year and does not expect to be treated as a PFIC in the current taxable year or in future taxable years. However, this conclusion 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 the Company’s gross income and assets. Accordingly, there can be no assurance that the Company will not be a PFIC for the current taxable year or in future taxable years.

 

If the Company 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 the Company’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 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, the portion of such U.S. Holder’s holding period for such Ordinary Shares that preceded the current taxable year). Under these default PFIC rules:

 

a U.S. Holder’s gain or excess distribution will be allocated ratably over such U.S. Holder’s holding period for its Ordinary Shares;

 

13

 

 

the amount of gain allocated to such U.S. Holder’s taxable year in which such U.S. Holder recognized the gain or received the excess distribution, or to the period in such U.S. Holder’s holding period before the first day of the Company’s taxable year in which it was a PFIC, will be taxed as ordinary income; and

 

the amount of gain allocated to other taxable years (or portions thereof) of such U.S. Holder and included in such U.S. Holder’s holding period will be taxed at the highest marginal tax rate in effect for that year and applicable to such U.S. Holder, and an additional amount equal to the interest charge generally applicable to underpayments of tax will be imposed in respect of the tax attributable to each such other taxable year (or portion thereof) of such U.S. Holder’s holding period.

 

In general, a U.S. Holder may avoid the adverse PFIC tax consequences described above in respect of the Ordinary Shares by making and maintaining a timely and valid QEF election (if eligible to do so) to include in income its pro rata share of the Company’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 the Company’s taxable year ends. In order to comply with the requirements of a QEF election, a U.S. Holder must receive certain information from the Company. The Company has not determined whether it will provide U.S. Holders with this information if it determines that it is a PFIC.

 

Alternatively, if the Company 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 the Company 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 the Company 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).

 

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 the Company 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 the Company receives a distribution from, or disposes of all or part of the Company’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 the Ordinary Shares under their particular circumstances.

 

14

 

 

Information Reporting and Backup Withholding

 

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, the Company 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 and proceeds from the sale, exchange, redemption or other taxable disposition of Ordinary Shares 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 Ordinary Shares

 

Scope

 

The following is a summary of the anticipated material Irish tax consequences for certain beneficial holders of the acquisition, ownership and disposal of Ordinary Shares. 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, that is neither a resident nor ordinarily resident in Ireland for Irish tax purposes and does not hold their Ordinary Shares, 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. The summary applies only to Non-Irish Holders who hold their Ordinary Shares 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 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 directly (and not beneficially through a broker or custodian (through DTC)). The Irish tax consequences of transactions in Ordinary Shares held directly are generally negative when compared with Ordinary Shares held through DTC. Any Non-Irish Holder contemplating holding their Ordinary Shares directly should consult their personal tax advisors as to the Irish tax consequences of acquiring, owning and disposing of such Ordinary Shares.

Irish Tax on Chargeable Gains (Irish CGT)

 

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 unless such Ordinary Shares are used in or for the purposes of a trade carried on by such Non-Irish Holder through an Irish branch or agency, are used, held or acquired for use by or for the purposes of an Irish branch or agency, or the shares derive the greater part of their value from Irish land.

 

A Non-Irish Holder of Ordinary Shares who is an individual and who is temporarily non-resident in Ireland may, under Irish anti-avoidance legislation, be liable to Irish tax on any chargeable gain realized on a disposal of Ordinary Shares during the period in which such individual is non-resident.

 

Stamp Duty

 

The rate of stamp duty (where applicable) on transfers of shares of Irish incorporated companies is 1% of the greater of the price paid or market value of the shares acquired. The Finance Act 2026 introduced an exemption to the charge to stamp duty on transfers of stocks and marketable securities in Irish incorporated companies listed on a relevant market where the market capitalisation of that company is less than €1 billion at closing on 1 December in the prior calendar year. Where this is the case, the company or the market operator can submit a notification to the Irish Revenue Commissioners and the exemption would apply from 1 January the following year or 14 days post-notification, whichever is the later. No such notification has been submitted with respect to ADSE Holdco to date and so this exemption is not applicable to the Ordinary Shares.

 

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, depending on the manner in which the Ordinary Shares are held. The Company has entered into arrangements with DTC to allow the Ordinary Shares 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.

 

Ordinary Shares Held Through DTC

 

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

 

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

 

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

 

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

 

there is no change in the beneficial ownership of such shares as a result of the transfer; and

 

the transfer into (or out of) DTC is not effected in contemplation of a sale of such shares by a beneficial owner to a third party.

 

16

 

 

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

 

Withholding Tax on Dividends (DWT)

 

Distributions made by the Company 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 the Company 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, the Company is responsible for withholding DWT prior to making such distribution.

 

General Exemptions

 

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

 

a person (not being a company) resident for tax purposes in a Relevant Territory (including the United States) and is neither resident nor ordinarily resident in Ireland (for a list of Relevant Territories for DWT purposes, please see Annex A to this prospectus);

 

a company resident for tax purposes in a Relevant Territory, provided such company is not under the control, whether directly or indirectly, of a person or persons who is or are resident in Ireland;

 

a company that is controlled, directly or indirectly, by persons resident in a Relevant Territory and who is or are (as the case may be) not controlled by, directly or indirectly, persons who are not resident in a Relevant Territory;

 

a company whose principal class of shares (or those of its 75% direct or indirect parent) is substantially and regularly traded on a stock exchange in Ireland, on a recognized stock exchange either in a Relevant Territory or on such other stock exchange approved by the Irish Minister for Finance; or

 

a company that is wholly owned, directly or indirectly, by two or more companies where the principal class of shares of each of such companies is substantially and regularly traded on a stock exchange in Ireland, a recognized stock exchange in a Relevant Territory or on such other stock exchange approved by the Irish Minister for Finance

 

and provided, in all cases noted above (but subject to “Ordinary—Shares Held by U.S. Resident Shareholders” below), the Company or, in respect of Ordinary Shares held through DTC, any qualifying intermediary appointed by the Company, 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:

 

its broker (and the relevant information is further transmitted to any qualifying intermediary appointed by the Company) 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 its Ordinary Shares are held through DTC; or

 

The Company’s transfer agent before the record date for the distribution if its Ordinary Shares are held outside of DTC.

 

17

 

 

Links to the various DWT Forms are available at: https://www.revenue.ie/en/companies-and-charities/dividend-withholding-tax/exemptions-for-non-residents.aspx. 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.

 

Ordinary Shares Held by U.S. Resident Shareholders

 

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 the Company). 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 the Company).

 

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 the Company’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 the Company’s transfer agent as soon as possible after receiving their Ordinary Shares.

 

If any holder of Ordinary Shares that is resident in the United States receives a distribution from which DWT has been withheld, the holder Ordinary Shares should generally be entitled to apply for a refund of such DWT from the Irish Revenue Commissioners, provided the holder of ordinary shares is beneficially entitled to the distribution.

 

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 the Company) 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 the Company’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 the Company’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.

 

Shares Held by Other Persons

 

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 the Company) 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.

 

18

 

 

Qualifying Intermediary

 

Prior to paying any distribution, the Company 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 the Company delivers or causes to be delivered to the qualifying intermediary the cash to be distributed.

 

The Company 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.

 

Additional Anti-avoidance Measures

 

Notwithstanding the above stated exemptions, payments of distributions to associated entities in jurisdictions that are on the EU list of non-cooperative jurisdictions or zero-tax jurisdictions may be subject to DWT on payment. Association for these purposes generally means a 50% ownership connection (assessed on the basis of share ownership, voting power or entitlement to profits on a distribution) or the ability to participate in the board of directors in a manner that causes, or could cause, the affairs of the company to be conducted in accordance with that person’s wishes.

 

Income Tax on Dividends Paid on Ordinary Shares

 

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 the Company. 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 the Company discharges the Irish income tax liability.

 

Capital Acquisitions Tax (CAT)

 

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 because Ordinary Shares 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 €400,000 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.

PLAN OF DISTRIBUTION

 

We are registering the resale from time to time by the selling securityholders of 27,493,949 Ordinary Shares, consisting of (i) 6,324,000 Ordinary Shares issued pursuant to the May 8 Subscription Agreements, (ii) 3,000,000 Ordinary Shares issued pursuant to the May 28 Subscription Agreement, and (iii) 18,169,949 Other 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 offered by the selling securityholders pursuant to this prospectus will be sold by each selling securityholder for its own account. We will not receive any proceeds from the sale of the Ordinary Shares by the selling securityholders.

 

The selling securityholders will pay any underwriting discounts 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, Nasdaq 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 the selling securityholders 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 our then current market price or in negotiated transactions. The selling securityholders reserve 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 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 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.

 

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;

 

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 Nasdaq;

 

through trading plans entered into by the selling securityholders 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 its securities on the basis of parameters described in such trading plans;

 

short sales;

 

20

 

 

distribution to employees, members, limited partners or stockholders of the selling securityholders;

 

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

 

by pledge to secured debt and other obligations;

 

delayed delivery arrangement;

 

to or through underwriters or broker-dealers;

 

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;

 

in options transactions;

 

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

 

any other method permitted pursuant to applicable law.

 

In addition, the selling securityholders 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 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 it deems 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 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 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 name of the applicable selling securityholder;

 

21

 

 

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 securityholder.

 

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 the 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 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 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 they 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 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 pay or the selling securityholders pay for solicitation of these contracts.

 

The selling securityholders 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 securityholders or borrowed from the selling securityholders or others to settle those sales or to close out any related open borrowings of stock and may use securities received from the selling securityholders 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 securityholders 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.

 

22

 

 

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.

 

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 securityholder. Upon our notification by the selling securityholders 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.

 

We have agreed to indemnify the selling securityholders against certain liabilities, including certain liabilities under the Securities Act, the Exchange Act or other federal or state law.

 

LEGAL MATTERS

 

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

 

EXPERTS

 

The consolidated financial statements of ADSE as of December 31, 2025 and 2024 and for each of the three years in the period ended December 31, 2025 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.

 

ENFORCEMENT OF CIVIL LIABILITIES

 

Certain of our directors and executive officers may be nonresidents of the United States. All or a substantial portion of the assets of such nonresident persons and of our company are located outside the United States. As a result, it may not be possible to effect service of process within the United States upon such persons or our company, or to enforce against such persons or us in U.S. Courts judgments obtained in such courts predicated upon the civil liability provisions of the federal securities laws of the United States. We have been advised by our Irish counsel that there is doubt as to the enforceability in Ireland against our company and our executive officers and directors who are non-residents of the United States, in original actions or in actions for enforcement of judgments of U.S. Courts, of liabilities predicated solely upon the securities laws of the United States.

Item 8. Indemnification of Directors and Officers

 

Pursuant to ADSE Holdco’s M&A, subject to the provisions of and so far as may be permitted by the Irish Companies Act, every director, officer or employee of ADSE Holdco, and each person who is or was serving at the request of ADSE Holdco as a director, officer or employee of another company, or of a partnership, joint venture, trust or other enterprise, shall be entitled to be indemnified by ADSE Holdco against all costs, charges, losses, expenses and liabilities incurred by him or her in the execution and discharge of his or her duties or in relation thereto, including any liability incurred by him or her in defending any proceedings, civil or criminal, which relate to anything done or omitted or alleged to have been done or omitted by him or her as a director, officer or employee of ADSE Holdco or such other company, partnership, joint venture, trust or other enterprise, and in which judgment is given in his or her favor (or the proceedings are otherwise disposed of without any finding or admission of any material breach of duty on his or her part) or in which he or she is acquitted or in connection with any application under any statute for relief from liability in respect of any such act or omission in which relief is granted to him or her by the court.

 

The Irish Companies Act prescribes that such an indemnity only permits a company to pay the costs or discharge the liability of a director or the secretary where judgment is given in any civil or criminal action in respect of such costs or liability, or where an Irish court grants relief because the director or secretary acted honestly and reasonably and ought fairly to be excused.

 

ADSE Holdco is permitted under its M&A and the Irish Companies Act to purchase directors’ and officers’ liability insurance, as well as other types of insurance, for its directors, officers and employees.

 

ADSE Holdco has entered into deeds of indemnity with its directors and ADSE GM executive officers. Given the director indemnification limitations arising under Irish law, ADSE Holdco’s subsidiary, ADSE GM and ADSE GM’s subsidiary, ads-tec Energy, Inc. have also entered into such deeds of indemnity. These agreements, among other things, require ADSE to jointly and severally indemnify ADSE Holdco’s directors and ADSE directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by any such director or executive officer in any action or proceeding arising out of their services as one of ADSE directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at ADSE’s request. We believe that these indemnification deeds are necessary to attract and retain qualified persons as directors and officers.

Item 10. Undertakings

 

a.The undersigned registrant hereby undertakes:

 

(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

 

(i)To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the “Securities Act”);

 

(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

 

(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

 

(2)That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

 

(4)To file a post-effective amendment to the registration statement to include any financial statements required by “Item 8.A. of Form 20-F” at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Item 8.A of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the SEC by the Registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

 

II-3

 

 

(5)That, for the purpose of determining liability of the undersigned registrant under the Securities Act to any purchaser,

 

(i)Each prospectus filed by the registrant pursuant to Rule 424(b)(3) (* 230.424(b)(3) of this chapter) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) (* 230.424(b)(2), (b)(5), or (b) (7) of this chapter) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) (* 230.415(a)(1)(i), (vii), or (x) of this chapter) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

 

(6)That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

 

(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

 

(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

 

(iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

 

(iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

 

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

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