TABLE OF CONTENTS

Ads-Tec Energy plc

(the “Company”)

(Registered in Ireland No. 700539)

Dear Shareholder

Introduction

I am writing to you to outline the background to the proposals to be put forward at the forthcoming Annual General Meeting (“AGM”) of the Company, all of which the board of directors (the “Board” or the “Directors”) considers to be in the best interests of the Company and the shareholders as a whole and are recommending for your approval.

Your attention is drawn to the Notice of the AGM of the Company. The AGM will be held at the offices of Arthur Cox LLP, Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland on 19 September 2023 at 2 pm (Dublin time) and the Notice is set out at page 3 of this document. The ordinary business to be transacted at the AGM is set out in proposals 1 to 4 in the Notice of meeting. These proposals are described further below.

Board Changes

In accordance with the provisions of the Company’s Articles of Association, Bazmi Husain, Salina Love and Kenneth R. Kent are deemed to have retired as directors of the Company at the conclusion of this year’s AGM.

Salina Love has offered herself for re-election at this year’s AGM, as further detailed in Proposal 4 below.

Bazmi Husain and Kenneth R. Kent have notified the Company that they do not intend to stand for re- election as directors of the Company. On behalf of the Board and myself personally, I would like to take the opportunity to thank Bazmi Husain and Kenneth R. Kent for their invaluable contribution to the Company since their appointment as directors of the Company.

Proposal 1 – To consider the Company’s statutory financial statements

This is a proposal to receive and consider the Company’s statutory financial statements for the year ended 31 December 2022.

Proposal 2 – To acknowledge the re-appointment of the statutory auditors

This item is on the agenda to allow the shareholders to acknowledge the re-appointment of the statutory auditors BDO AG Wirtschaftsprüfungsgesellschaft. This item is being put forward as a non-binding advisory proposal because, under the Companies Act 2014, the re-appointment of the auditors is automatic unless they resign or a proposal is put forward to remove them.

Proposal 3 – To authorise the Directors to fix the remuneration of the statutory auditors

This is a proposal authorising the Board to fix the remuneration of the statutory auditors in line with agreed terms of engagement as approved by the Audit Committee.

Proposal 4 – To re-elect Salina Love as a director of the Company

In accordance with the provisions of Article 158.1 of the Company’s Articles of Association, Salina Love is required to retire by rotation at the AGM and, being eligible, is offering herself for re-election as a director of the Company.

Further Action

Proxy votes must be received no later than 3 pm (Dublin Time) on Monday 18 September 2023.

Yours sincerely

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING

Why did I receive this notice?

What is the date, time and location of the Annual General Meeting?

We will hold the Annual General Meeting at 2 pm (Dublin Time) on Tuesday, 19 September 2023, at the offices of Arthur Cox LLP, Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland, subject to any adjournments or postponements. For directions to the meeting, you may contact our Company Secretary, Bradwell Limited at Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland.

Should we determine that alternative arrangements may be advisable or required, such as changing the date, time or location of the meeting or holding the meeting by other means such as by remote electronic communication, we will announce our decision by press release and post additional information on the Investor Relations section of our website (https://www.adstec-energy.com/). If you plan to attend the meeting in person, please check the Investor Relations section of our website prior to the meeting, as circumstances may change upon short notice.

Who is entitled to vote?

The Board has set Thursday, 24 August 2023 as the record date for the Annual General Meeting. All persons who were registered holders of Ads-Tec Energy plc ordinary shares at the close of business on that date are shareholders of record for the purposes of the Annual General Meeting and will be entitled to receive notice of, and to attend and vote at, the Annual General Meeting. Beneficial owners who, at the close of business on the record date, held their shares in an account with a broker, bank or other holder of record generally cannot vote their shares directly and instead must instruct the record holder how to vote their shares.

As of the close of business on the record date, there were 48,807,898 ordinary shares outstanding. Each shareholder of record is entitled to one vote per ordinary share on each matter submitted to a vote of shareholders. Your shares will be represented if you attend and vote at the Annual General Meeting.

How do I vote?

Registered shareholders (that is, shareholders who hold their shares directly with our transfer agent, Continental Stock Transfer & Trust Company) can vote in any of the following ways:

If I am a beneficial owner of shares held in street name, how do I vote?

If your shares are held beneficially in the name of a bank, broker or other holder of record (sometimes referred to as holding shares “in street name”), you will receive instructions from the holder of record that you must follow in order for your shares to be voted. If you wish to vote in person at the meeting, you must obtain a legal proxy from the bank, broker or other holder of record that holds your shares, and bring it, or other evidence of stock ownership, with you to the meeting.

What are the deadlines to submit my vote?

Proxy cards returned by mail must be received by 3 pm (Dublin Time) on Monday, 18 September 2023.

Can I revoke my proxy or change my vote after I have voted?

Yes. If you are a registered shareholder and previously voted, you may revoke your proxy or change your vote by:

If you are a beneficial owner of shares held in street name, you must contact the holder of record to revoke a previously authorised proxy.

What do I need to be admitted to the Annual General Meeting?

For shareholders who plan to attend the Annual General Meeting in person, at the entrance to the Annual General Meeting in Dublin, we will request to see valid photo identification, such as a driver’s license or passport. We will also need to determine if you owned ordinary shares on the record date by:

If you are acting as a proxy, we will need to review a valid written legal proxy signed by the registered owner of the ordinary shares granting you the required authority to attend the meeting and vote such shares.

What constitutes a quorum?

In order to establish a quorum at the Annual General Meeting there must be at least two shareholders present in person or by proxy who have the right to attend and vote at the meeting and who together hold shares representing more than 50% of the votes that may be cast by all shareholders of record. For purposes of determining a quorum, abstentions and broker “non-votes” are counted as present.

How are votes counted?

You may vote “FOR”, “AGAINST” or “ABSTAIN” with respect to each of the proposals presented. A vote “FOR” will be counted in favour of the proposal or director nominee and a vote “AGAINST” will be counted against each proposal or nominee. Except as described below, an “ABSTAIN” vote will not be counted “FOR” or “AGAINST” and will have no effect on the voting results for any of the proposals in this notice. Link Registrars Limited will monitor all votes and assist us in tabulating the votes.

What is a “broker non-vote” and how does it affect voting?

If you are a beneficial owner whose shares are held of record by a broker, we encourage you to instruct the broker how to vote your shares. If you do not provide voting instructions, your shares will not be voted on any proposal for which the broker does not have discretionary authority to vote. This is called a “broker non-vote”, which occurs for proposals considered “non-routine” under NASDAQ rules. Your broker will, however, still be able to register your shares as being present at the Annual General Meeting for purposes of determining the presence of a quorum and will be able to vote on “routine” proposals.

The “routine” proposals in this notice are Proposal 1, 2 and 3, for which your broker has discretionary voting authority under the NASDAQ rules to vote your shares, even if the broker does not receive voting instructions from you. Proposal 4 is considered “non-routine” such that, if you are a beneficial owner whose shares are held of record by a broker and you do not provide voting instructions, a broker non- vote will occur and your shares will not be voted on this proposal.

What is the vote required to approve each of the proposals discussed in the notice?

The chart below summarises the voting requirements and effects of broker non-votes and abstentions on the outcome of the vote for the proposals at the Annual General Meeting.

Submission of Future Shareholder Proposals

Our annual general meeting of shareholders for 2024 is expected to be held in September 2024. In accordance with the rules established by the SEC, any shareholder proposal submitted and to be included in the notice for that meeting must be received by us by 1 May 2024. If you would like to submit a shareholder proposal to be included in that notice, you should send your proposal to our Company Secretary, Bradwell Limited, Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland. In order for your proposal to be included in the notice, the proposal must comply with the requirements established by the SEC and our Articles of Association.

Pursuant to our Articles of Association, a shareholder must give notice of any intention to present a proposal at the Annual General Meeting, including a proposal to appoint a director, not less than 60 nor more than 90 days before the first anniversary of the preceding year’s annual general meeting (“traditional advance notice”). Subject to our Articles of Association, any notice of an intention to present a proposal pursuant to traditional advance notice must be received by our Company Secretary on or after 21 June 2024 but no later than 21 July 2024.

Irish law currently provides that shareholders holding 10% or more of the total voting rights may request that the directors call an extraordinary general meeting at any time. The shareholders who wish to request an extraordinary general meeting must deliver to Bradwell Limited, Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland, a written notice, signed by the shareholders requesting the meeting and stating the purposes of the meeting. If the directors do not, within 21 days of the date of delivery of the request, proceed to convene a meeting to be held within 2 months of that date, those shareholders (or any of them representing more than half of the total voting rights of all of them) may themselves convene a meeting, but any meeting so convened cannot be held after the expiration of 3 months from the date of delivery of the request. These provisions of Irish law are in addition to, and separate from, the requirements that a shareholder must meet in order to have a proposal included in the notice under the rules of the SEC.
