Share Purchase Plan

Am I eligible?

You are an eligible shareholder if all of the following apply:

• You were registered as a holder of Sparc Technologies shares at 7:00pm AEST on Wednesday, 19 August 2026 (the record date).
• Your registered address on the share register is in Australia or New Zealand.
• You are not in the United States, and you are not applying for the account or benefit of a person in the United States.

The A$30,000 maximum applies per shareholder, including across joint holdings, multiple registered holdings, and any holding in which you have a beneficial interest. Participation is optional and the right to participate cannot be transferred to anyone else.

How to apply

1. Go to the Xcend investor portal and sign in with your SRN or HIN and your postcode.
2. Open your personalised application form and choose the parcel you want to apply for.
3. Pay by BPAY or EFT using the instructions on your application form, before 5:00pm AEST on Thursday, 24 September 2026.

If you pay by BPAY or EFT you do not need to return the application form. Cheques, cash and money orders are not accepted. Your bank may apply its own limits to BPAY and EFT payments, so it is worth checking these before the closing date.

Application amounts

Applications must be for one of the parcels below, with a minimum of A$1,000 and a maximum of A$30,000.

If your payment does not match one of these amounts exactly, it will be applied to the highest parcel below the amount paid and the balance refunded without interest.

Key dates

This timetable is indicative only. The Company may vary these dates, including closing the offer early or accepting late applications, subject to the ASX Listing Rules and the Corporations Act.

Issue price

The issue price of A$0.175 per new share is the same price as the Company’s recent placement to professional and sophisticated investors, announced on Thursday, 20 August 2026. Relative to trading before the offer was announced, it represents:

• a discount of approximately 16.7% to the closing price of A$0.210 on Monday, 17 August 2026, the last trading day before the offer was announced; and
• a discount of approximately 19.7% to the five-day volume weighted average price of A$0.218 up to and including 17 August 2026.

The share price may rise or fall between the date of the offer and the date new shares are issued, and may trade below the issue price. New shares rank equally in all respects with existing shares on issue.

Use of funds

The Board presently intends to apply funds raised under the SPP towards:

• commercialisation activities for ecosparc®;
• supporting the Company’s investment in Sparc Hydrogen;
• research and development of new products; and
• general working capital.

This is a statement of current intentions. Intervening events and new circumstances may affect how funds are ultimately applied.

Scale back

The Company is targeting a maximum of A$1,750,000 before costs, being a maximum of 10,000,000 new shares. The Board reserves the right to accept oversubscriptions, and to reject or scale back applications in whole or in part at its absolute discretion, or to close the offer early.

If a scale back applies, you may not receive all of the new shares you applied for, and excess application monies will be refunded without interest. Shareholders who wish to participate are encouraged to act promptly. Full details are set out in the Offer Booklet.

Custodians

Custodians applying on behalf of beneficiaries must submit a custodian certificate with their application. Requirements are set out in full in the Offer Booklet.
