Share Purchase Plan Closes Significantly Oversubscribed

Sparc Technologies Limited ( ASX: SPN ) ( Sparc, Sparc Technologies or the Company ) is pleased to announce the results of its Share Purchase Plan ( SPP ) announced on 1 May 2025. The Company received valid applications from eligible shareholders totaling A$1,026,214 which was well in excess of the original A$500,000 targeted under the SPP. The SPP closed at 5:00PM (AEST) on Thursday 29 May 2025.

Sparc Managing Director, Mr Nick O’Loughlin commented:

“High demand received under the SPP is a testament to the strong level of support from the Company’s loyal shareholders. Funds from the SPP and share placement completed in early May provides a strong financial platform for the Company to deliver on its key objectives, which includes commercialising its ecosparc[®] graphene based additives within protective coatings and supporting Sparc Hydrogen’s progression through piloting activities at Roseworthy in South Australia. I would like to thank participating shareholders for their confidence and support.”

The terms and conditions of the SPP as set out in the SPP Offer Booklet provided the Company with discretion to accept additional funds should the Company receive valid applications over the original target amount. Accordingly, due to the strong demand from eligible shareholders, the Company has exercised this discretion and has decided to increase the size of the SPP to A$1,026,214 (before costs) in order to accept all valid applications in full. A total of 6,841,491 fully paid ordinary shares ( New Shares ) will be issued under the SPP pursuant to ASX Listing Rule 7.2 Exception 5.

The strong support for the SPP follows the successful completion of a share placement ( Placement ), which raised A$2.2M (including participation by the Company’s directors for a total of A$60,000, subject to shareholder approval under ASX Listing Rule 10.11, before costs), as announced by the Company on 1 May 2025.

The New Shares will be issued on Thursday, 5 June 2025 in line with the SPP timetable and an Appendix 2A will be released to the market on the same date. The New Shares will be issued at the same price as shares issued under the Placement, being A$0.15 each.

The Company would like to thank shareholders for their strong support of the SPP.

This announcement has been authorised for release to the ASX by the board of directors of the Company.

About Sparc Technologies

Sparc Technologies Limited (‘Sparc’, ASX: SPN) is an Australian technology company developing solutions that enhance environmental and sustainability outcomes for global industries. Sparc has two transformative technology areas in which it works: green hydrogen and graphene enhanced materials. Sparc conducts research and development in-house and has extensive engagement and relationships with the university sector in Australia and globally.

1. Sparc Hydrogen is a joint venture between Sparc Technologies, Fortescue Limited and the University of Adelaide which is pioneering next-generation green hydrogen production technology. Photocatalytic water splitting (PWS) is an emerging method to produce green hydrogen without electrolysers - using only sunlight, water and a photocatalyst. Given lower infrastructure requirements and energy use, PWS has the potential to deliver cost and flexibility advantages over existing hydrogen production methods.

2. Sparc has developed and is commercialising a graphene based additive product, ecosparc[®] , which at low dosages significantly improves the performance of commercially available epoxy-based protective coatings. Sparc has commissioned a manufacturing facility to produce ecosparc[®] and is engaging with global coatings companies and large asset owners on testing, trials and commercial partnerships.
