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”) consider 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 appended to this letter at Schedule 1 (the “Notice”). The AGM will be held at the offices of our Irish counsel, Arthur Cox LLP at Ten Earlsfort Terrace, Dublin 2, Ireland, D02 T380 on 14 December 2023 at 1pm (Dublin time). The business to be transacted at the AGM is set out in Proposals 1 to 5 in the Notice. These proposals are described further below.

Board Changes

In accordance with the provisions of Regulation 158 of the Company’s constitution (the “Constitution”), the term of service for each of the Directors in Class I (the “Class I Directors”) terminates at the conclusion of this year’s AGM. Our Class I Directors are Amir Bader and Thomas Hawkins.

Amir and Thomas will be seeking re-election at this year’s AGM, as further detailed in Proposals 1 and 2 below.

As Ordinary Business:

Proposal 1 – To re-elect Amir Bader for a three-year term

In accordance with the provisions of Regulation 158 of the Constitution, Amir is required to retire by rotation at the AGM and, being eligible, he is offering himself for re-election. Amir’s performance has been formally evaluated and the Board considers that Amir’s performance continues to be effective and that he demonstrates commitment to his role as Director.

Proposal 2 – To re-elect Thomas Hawkins for a three-year term

In accordance with the provisions of Regulation 158 of the Constitution, Thomas is required to retire by rotation at the AGM and, being eligible, he is offering himself for re-election. Thomas’ performance has been formally evaluated and the Board considers that Thomas’ performance continues to be effective and that he demonstrates commitment to his role as Director.

Proposal 3 – To acknowledge the re-appointment of the statutory auditor

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

Proposal 4 – To authorise the Directors to fix the remuneration of the statutory auditor

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

As Special Business:

Proposal 5 – To amend the Company’s Equity Incentive Plan (the “Plan”) to increase the number of ordinary shares authorized under the Plan

Having considered and evaluated the Plan, the Directors have determined that, in order to satisfy current and projected equity compensatory grants to the Company’s employees (including executive officers), consultants and non-employee directors, the number of ordinary shares currently authorized to be issued to the Company’s employees (including executive officers), consultants and non-employee directors under the Plan is required to be increased by 1,500,000 ordinary shares to a total of 1,731,019 ordinary shares, representing approximately 13.88% of the Company’s issued share capital on a fully diluted basis as at 15 November 2023, being the Record Date (as defined in the Notice).

We are therefore under this proposal asking shareholders for their approval for the Company to amend the Plan to increase the number of ordinary shares currently authorized under the Plan by the number of ordinary shares outlined above.

Further Action

You may submit your proxy over the internet by logging on to www.cstproxy.com. To log on, you will need your control number which is printed on your proxy card. Online proxy votes must be received no later than 11.59pm (Eastern time) on 13 December 2023.

We recommend that you review the further information on the process for, and deadlines applicable to, voting, attending the meeting and appointing a proxy under “Questions and Answers about the Annual General Meeting” at Schedule 2.

Recommendation

Your Board believes that the proposals to be put forward at the AGM are in the best interests of the Company and its shareholders. Accordingly, your Directors unanimously recommend that you vote in favour of the proposals as they intend to do in respect of all the ordinary shares which can be voted by them.

Yours sincerely

/s/ Ophir Sternberg

(the “Company”)

(Company Number 722009)

QUESTIONS AND ANSWERS ABOUT THE 2023 ANNUAL GENERAL MEETING

Why did I receive this notice?

We are providing this notice in connection with the solicitation by the Board of proxies to be voted at the Annual General Meeting. You received this notice because you were a shareholder of record as of the close of business on 15 November 2023.

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

We will hold the Annual General Meeting at 1pm (Dublin time) on 14 December 2023, at the offices of our Irish counsel, Arthur Cox LLP at Ten Earlsfort Terrace, Dublin 2, Ireland, D02 T380, subject to any adjournments or postponements. For directions to the meeting, you may contact our Company Secretary, Bradwell Limited c/o SMX (Security Matters) PLC, Mespil Business Centre, Mespil House, Sussex Road, Dublin 4, Ireland, D04 T4A6.

Who is entitled to vote?

The Board has set 15 November 2023 as the record date for the Annual General Meeting. All persons who were registered holders of SMX (Security Matters) PLC’s Ordinary Shares of US$0.0022 each (“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 2,924,480 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 or if you submit a completed proxy by the voting deadlines set forth below.

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:

- Online: Go to www.cstproxyvote.com to vote your proxy online using the control number that you were provided with on your proxy card or Notice of Internet Availability. You will need to follow the instructions on the website.

- By Mail: You may mark, sign, date and return your proxy card in the enclosed postage paid envelope. Proxies must be received by the deadlines set forth below. If you vote online, your electronic vote authorizes the named proxies in the same manner as if you signed, dated and returned a proxy card by mail.

- In Person: Attend the Annual General Meeting in Dublin or send a personal representative with an appropriate proxy to vote at the meeting. Please contact our Company Secretary, Bradwell Limited c/o SMX (Security Matters) PLC, Mespil Business Centre, Mespil House, Sussex Road, Dublin 4, Ireland, D04 T4A6 for additional information about sending a personal representative on your behalf. For information about how to attend the Annual General Meeting, please see “What do I need to be admitted to the Annual General Meeting?” below.

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?

- Online: Proxy votes cast online must be received by 11.59pm (Eastern Time) on 13 December 2023.

- Mail: Proxy cards returned by mail must be received by the start of the Annual General Meeting.

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

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

- voting online at a later date, as set forth above before the closing of those voting facilities at 11.59 pm (Eastern Time) on 13 December 2023;

- attending the Annual General Meeting in Dublin and submitting a new poll card during the meeting; or

- sending a written notice of revocation to our Company Secretary, Bradwell Limited c/o SMX (Security Matters) PLC, Mespil Business Centre, Mespil House, Sussex Road, Dublin 4, Ireland, D04 T4A6 which must be received before the commencement of the Annual General Meeting. 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:

- asking to review evidence of your share ownership as of 15 November 2023, such as your brokerage statement. You must bring such evidence with you in order to be admitted to the meeting; or

- verifying your name and share ownership against our list of registered shareholders.

2

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 the 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 favor 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. Continental Stock Transfer & Trust Company 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 Proposals 3 and 4, 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. Proposals 1, 2 and 5 are 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 these proposals.

Submission of Future Shareholder Proposals

Our annual general meeting of shareholders for 2024 is expected to be held in December 2024. In accordance with the rules established by the SEC, any shareholder proposal submitted pursuant to Rule 14a-8 of the Exchange Act to be included in the notice for that meeting must be received by us by 1 July 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 c/o SMX (Security Matters) PLC, Mespil Business Centre, Mespil House, Sussex Road, Dublin 4, Ireland, D04 T4A6. In order for your proposal to be included in the notice, the proposal must comply with the requirements established by the SEC and our constitution.

Pursuant to our constitution, 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”).

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 Mespil Business Centre, Mespil House, Sussex Road, Dublin 4, Ireland, D04 T4A6, 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 two 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 three 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.
