TO APPOINT A PROXY BY COMPLETING THE PROXY FORM

STEP 1 APPOINTMENT OF PROXY

Indicate who you want to appoint as your proxy.

If you wish to appoint the Chairman of the Meeting as your proxy, mark the box in Step 1. If you wish to appoint someone other than the Chairman of the Meeting as your proxy, please write the full name and email address of that individual or body corporate in Step 1. A proxy need not be a Shareholder. Do not write the name of the issuer company (i.e. Magontec) or the registered securityholder (i.e. you) in the space.

Default to Chairman of the Meeting

Any directed proxies that are not voted on a poll at the Meeting by a Shareholder’s appointed proxy will automatically default to the Chairman of the Meeting, who is required to vote proxies as directed on a poll.

If you appoint the Chairman of the Meeting as your proxy (or the Chairman is appointed by default) and you do not specifically direct how your proxy is to vote on a Resolution, then, by completing and submitting your Proxy Form, you will be expressly authorising the Chairman to exercise your proxy as the Chairman sees fit in relation to the applicable Resolution, even when a resolution is connected directly or indirectly with the remuneration of one or more members of the Company’s KMP.

As stated in the Notice of Meeting, the Chairman intends to vote all available (including undirected) proxies in favour of all Resolutions put to Shareholders at the Meeting, subject to the applicable voting exclusions set out in the Notice of Meeting.

STEP 3 SIGN THE FORM

The Proxy Form must be signed as follows:

Individual: This form is to be signed by the Shareholder.

Joint Holding : where the holding of Shares is in more than one name, any of the joint Shareholders may sign.

Power of Attorney: to sign under a Power of Attorney, you must have already lodged the Power of Attorney with the Magontec share registry. Alternatively, attach a certified photocopy of the Power of Attorney to this Proxy Form when you return it.

Companies: this form must be signed by a Director jointly with either another Director or a Company Secretary. Where the company has a Sole Director who is also the Sole Company Secretary, this form should be signed by that person. If the company (pursuant to section 204A of the Corporations Act 2001 (Cth)) does not have a Company Secretary, a Sole Director can sign alone. Please indicate the office held by signing in the appropriate place.

STEP 4 LODGEMENT

Proxy Forms (and any Power of Attorney under which it is signed) must be received at an address given below by 11:00am (AEST) on Sunday, 10 May 2026 , being not later than 48 hours before the commencement of the Meeting . Any Proxy Form received after that time will not be valid for the scheduled Meeting.

Appointment of a second proxy

You are entitled to appoint up to two proxies to attend the Meeting and vote on a poll. If you wish to appoint a second proxy, an additional Proxy Form may be obtained by contacting Magontec’s share registry or you may copy this form and return them both together. To appoint a second proxy you must:

(a) on each of the first Proxy Form and the second Proxy Form, state the percentage of your voting rights or the number of Shares applicable to that form and proxy appointment. If the appointments do not specify the percentage or number of votes that each proxy may exercise, each proxy may exercise half your votes. Fractions of votes will be disregarded; and

(b) return both Proxy Forms together in the same envelope.

STEP 2 VOTING DIRECTIONS TO YOUR PROXY

To direct your proxy how to vote, mark one of the boxes opposite each item of business. All your Shares will be voted in accordance with such a direction unless you indicate only a portion of Shares are to be voted on any item by inserting the percentage or number of Shares that you wish to vote in the appropriate box or boxes. If you do not mark any of the boxes on a given item, your proxy may vote as he or she chooses. If you mark more than one box on an item for all your Shares, your voting direction to your proxy on that item will be invalid.

Proxy that is a body corporate

Where a body corporate is appointed as your proxy, the representative of that body corporate attending the Meeting must have provided an “Appointment of Corporate Representative” form prior to admission in accordance with the instructions in the Notice of Meeting. An Appointment of Corporate Representative form can be obtained from Magontec’s share registry or online at https://boardroomlimited.com.au/investor-forms/.
