All Resolutions will be by poll

Voting on each Resolution considered at the meeting will be conducted by a poll. The Board considers voting by a poll to be in the interests of the Shareholders as a whole and ensures the views of as many Shareholders as possible are represented at the Meeting. Shareholders who are unable to attend the AGM are encouraged to vote in advance of the Meeting by submitting a proxy.

Joint holders

When joint holders are named in the register of members, only one joint holder may vote. If more than one of the joint holders is present at the Meeting, only the person whose name appears first in the register of members will be entitled to vote. If more than one holder votes at the meeting, only the vote of the first named of the joint holders in the register of members will be counted.

Proxies

All Shareholders who are entitled to participate in and vote at the AGM have the right to appoint a proxy to participate in the AGM and vote in their place. A proxy need not be a Shareholder and can be an individual or a body corporate.

You can direct your proxy how to vote (i.e. to vote ‘for’ or ‘against’, or to ‘abstain’ from voting on, each Resolution) by following the instructions either online or on the hard copy voting form. A proxy may decide whether and, if so, how to vote on an item of business, except where the proxy is required by law or the constitution to vote, or abstain from voting, in his or her capacity as proxy. If a proxy is directed how to vote on an item of business, the proxy may only vote on the item as directed. If a proxy is not directed how to vote on an item of business, the proxy may vote as he or she thinks fit.

For your proxy appointment to be effective, it must be received by Boardroom Pty Limited not less than 48 hours before the time for holding the AGM (that is by no later than 11.00am (AEDT) on 26 November 2025).

If you appoint the Chairman as your proxy but do not direct the Chairman on how to vote, then by completing and submitting your voting instructions you are expressly authorising the Chairman to vote in favour of each item of business, even when an item of business is directly or indirectly connected to the remuneration of a member of the key management personnel of CleanSpace Holdings Limited. Subject to the applicable voting exclusions, the Chair intends to vote all available (including undirected) proxies in favour of all Resolutions, subject to the applicable voting exclusions.

If you are entitled to cast two or more votes, you may appoint two proxies and you may specify the proportion or number of votes that each proxy is appointed to exercise. If your appointment does not specify the proportion or number of your voting rights, each proxy may exercise half your votes (disregarding fractions).

The appointment of one or more duly appointed proxies will not preclude a Shareholder from attending the meeting and voting personally. If the Shareholder votes on a Resolution, the proxy must not vote as the Shareholder’s proxy on that Resolution.

Voting Intentions of the Chair of the meeting

The Chair of the Meeting intends to vote all available proxies FOR all resolutions.

The Chair of the meeting may vote an undirected proxy (i.e. a proxy that does not specify how it is to be voted) provided the Shareholder who has lodged the proxy has given express voting direction to the Chair to exercise the undirected proxy. If you complete a proxy form that authorises the Chair of the meeting to vote on your behalf as proxy, and you do not mark any of the boxes to indicate to the Chair how your vote should be cast, then you will have been taken to have expressly authorised the Chairman to exercise your proxy on Resolution 1. In accordance with this express authority provided by you, the Chairman will vote FOR Resolution 1.

If you wish to appoint the Chair of the Meeting as your proxy, and you wish to direct the Chair as to how to vote, please tick the appropriate boxes on the proxy form.

ANNUAL GENERAL MEETING EXPLANATORY STATEMENT

This Explanatory Statement for the 2025 Annual General Meeting ( AGM ) has been prepared for the information of Shareholders in connection with the business to be conducted at the AGM.

The purpose of this Explanatory Statement is to provide information which the Directors believe to be material to Shareholders in deciding whether or not to pass the Resolutions.

1. ANNUAL REPORT

1.1 General

The first agenda item is to receive the Annual Report of the Company for the year ended 30 June 2025.

1.2 Corporations Act

Section 317 of the Corporations Act 2001 (Cth) requires the directors to lay before the Annual General Meeting the Financial Report, the Directors' Report (including the Remuneration Report) and the Auditor's Report for the last financial year that ended 30 June 2025.

The Annual Report is available on the Company’s website and a printed copy has been sent to those shareholders who requested it.

In accordance with sections 250S and 250SA of the Corporations Act, Shareholders present at the Annual General Meeting will be provided with a reasonable opportunity to:

• (a) ask questions or make comment to the Directors present on the management of the Company and Remuneration Report; and

• (b) ask questions or make comment to the Auditor about the conduct of the audit and the preparation and content of the Auditor's Report.

No formal resolution to adopt the Annual Report will be put to the Shareholders at the Annual General Meeting.

Shareholders who are unable to attend the AGM are able to submit written questions to the Chairman or the auditor about:

• (a) The preparation and the content of the 2025 Auditor's Report;

• (b) The conduct of the 2025 audit;

• (c) Accounting policies adopted by the Company in relation to the preparation of the 2025 financial statements; and

• (d) The independence of the Auditor in relation to the conduct of the 2025 audit.

The questions will need to be submitted no later than five (5) business days before the Annual General Meeting to the Company Secretary at the Company's Registered Office or via email to secretary@cleanspacetechnology.com.au.

2. RESOLUTION 1 – ADOPTION OF THE REMUNERATION REPORT

2.1 General

In accordance with Section 250R(2) of the Corporations Act, at a listed company's Annual General Meeting, a resolution that the Company’s Remuneration Report be adopted must be put to the vote. Section 250R(3) of the Corporations Act provides that the vote on the resolution is advisory only and does not bind the Directors or the Company.

CleanSpace Holdings Limited | Notice of Annual General Meeting

Page 7 of 10

In accordance with Section 300A, the Remuneration Report sets out the Company’s remuneration arrangements for Key Management Personnel. The Remuneration Report is part of the Directors’ Report contained in the Annual Financial Report for the financial year ending 30 June 2025. A reasonable opportunity will be provided for discussion of the Remuneration Report at the Annual General Meeting.

2.2 Voting Consequences

Under the Corporations Act, companies are required to put to shareholders a resolution proposing the calling of another meeting of shareholders to consider the appointment of directors of the company (“Spill Resolution”) if, at two consecutive Annual General Meetings, at least 25% of the votes cast on the Remuneration Report are voted against the adoption of the Remuneration Report and at the first of those Annual General Meetings a Spill Resolution was not put to vote. If required, the Spill Resolution must be put to vote at the second of those Annual General Meetings.

If more than 50% of votes are cast in favour of a Spill Resolution, the Company must convene a shareholder meeting (“Spill Meeting”) within 90 days of the second Annual General Meeting. At that meeting, all directors who were in office at the time of the Directors’ Report, other than the managing director, will cease to hold office immediately before the Spill Meeting. Those persons who are elected or re-elected at the Spill Meeting will be the directors of the company. Note those directors who ceased to hold office immediately prior to the Spill Meeting may stand for re-election.

At the 2024 AGM, Shareholders passed the resolution to adopt the Company’s 2024 Remuneration Report with a 95.58% for vote. Accordingly, a Spill Resolution is not required at this AGM.

Shareholders of the Company will be provided with the opportunity to ask questions about or make comments on the Remuneration Report.

Board Recommendation

Noting that each director has a personal interest in their own remuneration from the Company as set out in the Remuneration Report, the Board recommends that Shareholders vote in favour of this resolution.

3. RESOLUTION 2 & 3 - RE-ELECTION OF DIRECTORS

3.1 General

In accordance with ASX Listing Rule 14.5, a public listed company must hold an election of directors at each annual general meeting. Further, in accordance with ASX Listing Rule 14.4 and the Company’s Constitution, a director must not hold office (without re-election) past the third annual general meeting following the director’s appointment.

Mr. Graham McLean, Non-Executive Director and Ms. Lisa Hennessy, stand for re-election at this meeting via rotation.

Mr McLean is a very experienced senior executive, having worked with NYSE-listed Stryker for 16-years, and brings significant operational and healthcare experience.
