Announcement PDF Gold Hydrogen Limited, Level 14, 110 Eagle Street (GPO Box 801) Brisbane, Qld 4000 | info@goldhydrogen.com.au | ABN 74 647 468 899 | 1 23 October 2026 ASX Announcement R&D Funding Arrangements The Board of Directors of Gold Hydrogen Limited (GHY, the Company) is pleased to advise that the Company has entered into an R&D loan facility with Rockford Capital (Rockford). The facility encompasses a two-staged approach, covering FY2026 and – at the Company’s election – FY2027. In this regard the Company has been working with its R&D and taxation advisors Deloitte on the R&D claim for FY2026, which incorporates the 2025 drilling campaign. The Rockford R&D loan facility provides for an amount of up to $2 million to be loaned against the FY2026 R&D claim, which has been verified by Deloitte. This is expected to be settled and received in the next days. This $2 million Rockford loan facility is secured against the Company’s projected FY2026 R&D claim. The facility has a 1.75% establishment fee and bears interest at 16.5% per annum with a 120 day minimum interest period. Furthermore, and at the Company’s election, it can immediately move to seek up to a further $4 million in loan funding against its projected FY2027 R&D claim, which would encompass the 2026 well testing campaign and other eligible R&D-related costs. The loan terms would mirror those for FY2026, and be secured against the Company’s projected FY2027 R&D claim, and must be repaid by 30 April 2028. As shareholders and interested investors would be aware, the Company has a history of successful R&D claims based on its novel and pioneering exploration and appraisal work in pursuit of Natural Hydrogen and Helium discoveries, and ultimately commercial production, on the Yorke Peninsula in South Australia. In 2023, the Company drilled the first Natural Hydrogen purposed wells in Australia, and is still the only company to have specifically drilled and tested wells for Natural Hydrogen in Australia. Access to this funding stream will provide the Company with the ability to continue to compile and analyze the results of its recent well testing campaign, and pursue the preliminary studies associated with the potential commercialization pathways identified for both Natural Hydrogen and Helium. This announcement has been authorised for release by the Managing Director.
