ASX ANNOUNCEMENT

Strategic Alliance Disclosure Update

HyTerra Ltd (ASX: HYT) ( HyTerra or the Company ) refers to Fortescue Future Industries Technologies Pty Ltd’s (“ Fortescue ”) A$21.9M investment in HyTerra that was approved by HyTerra shareholders on 5 December 2024 with ~98% of votes cast in favour of the resolution (the “ Subscription ”).

The Notice of Meeting sent to the Company’s shareholders on 5 November 2024 in relation to the Subscription included disclosure with respect to Fortescue’s potential acquisition of up to 49.75% of HyTerra’s issued shares. As at the date of this announcement, Fortescue holds 644,117,647 HyTerra shares (representing ~39.52% of HyTerra’s issued shares), along with 322,058,824 unquoted options (each exercisable for A$0.051 on or before 6 December 2027).

The Notice of Meeting did not include details of all of Fortescue’s associates, namely Fortescue Ltd and its other subsidiaries (the “ Fortescue Group Companies ”), nor any substantial shareholders of Fortescue Ltd holding an indirect relevant interest in HyTerra shares as a result of the Subscription. Details of the Fortescue Group Companies and substantial shareholders of Fortescue Ltd are publicly disclosed on an annual basis by Fortescue Ltd in its Annual Report (current as at the date of that report), a copy of which is available on Fortescue Ltd’s website and ASX platform.

Fortescue has provided the Company with a voluntary notice of change of interests of substantial holder, which notifies of a change in its voting power in HyTerra by 0.14% and which includes details of the Fortescue Group Companies and all persons who hold a relevant interest in the HyTerra shares held by Fortescue. A copy of this notice is attached to this announcement.

The Company continues to progress its Strategic Alliance with Fortescue and to pursue the exploration drilling program at the Nemaha Project that is being funded by the Subscription proceeds.

This announcement has been authorised for release by the Chairman of HyTerra Ltd.

HYTERRA. A WORLD OF OPPORTUNITY.

Exploring for natural hydrogen and helium resources near major industrial hubs. White hydrogen's potential as a low-carbon feedstock or fuel has spurred millions in new investment and created a world rich with opportunities for first movers.

==> picture [244 x 231] intentionally omitted <==

HyTerra was the first company to list on the ASX with a focus on white hydrogen, which is generated naturally by the Earth. White hydrogen potentially has much lower production costs and carbon emissions than man-made hydrogen.

Our Nemaha Project in Kansas, USA, holds 100% owned and operated leases across the emerging Nemaha Ridge natural hydrogen and helium play fairway. Our Geneva Project in Nebraska, USA, is a 16% earn-in interest in a Joint Development with Natural Hydrogen Energy LLC targeting natural hydrogen and helium.

Both projects could be connected via railways, roads, and/or pipelines to multiple nearby offtakers, including ethanol and ammonia manufacturers, and petrochemical plants.
