Helium One Global Ltd

("Helium One" or "the Company")

Fundraise of £3.5 million (approximately US$4.7m) and Retail Offer

Helium One Global (AIM: HE1), the primary helium explorer in Tanzania with a 50% working interest in the Galactica-Pegasus helium development project in Colorado, USA (the "Galactica Project"), is pleased to announce a fundraise (the "Fundraise" or the "Subscription") of £3.5 million (approximately US$4.7 million), before expenses, by way of a direct subscription of 583,333,334 new Ordinary Shares ("Fundraise Shares") at a price of 0.6 pence per new ordinary share (the "Issue Price").

In addition to the Fundraise, the Company also intends to make an offer of new ordinary shares at the Issue Price on the Winterflood Retail Access Platform (WRAP) (the "Retail Offer") targeting gross proceeds of £1.0 million (approximately US$1.3 million). The Retail Offer is intended to provide existing shareholders of the Company in the United Kingdom an opportunity to participate in the equity fundraise. A separate announcement will be made shortly regarding the Retail Offer and its terms. The final number of shares to be issued pursuant to the Retail Offer (the "Retail Offer Shares") will be announced as soon as reasonably practicable after the close of Retail Offer.

Summary

·  Proposed Subscription to raise gross proceeds of £3.5 million (approximately US$4.7 million) (before expenses) at the Issue Price.

·    Additional Retail Offer targeting gross proceeds of £1.0 million (approximately US$1.3 million).

·    The Fundraise is being subscribed for by institutional investors.

·    Issue Price of 0.6 pence per new ordinary share represents a discount of 17.6 per cent. to the closing mid-market price of the Company's existing ordinary shares on 25 March 2026, the last practicable date prior to this announcement.

·   The net proceeds of the Fundraise will be utilised to further advance the Galactica Project, maintain the southern Rukwa Helium Project whilst pursuing the farmout strategy, and for general working capital purposes.

Lorna Blaisse, Chief Executive Officer, commented:

"This fundraise allows us to maintain momentum across our portfolio, supporting continued advancement at the Galactica‑Pegasus project in the US while progressing the southern Rukwa Helium Project as we actively pursue a strategic partner; activities that the Board believe will position the Company to unlock value and drive long‑term shareholder returns."

Background to and Reasons for the Fundraise

With the announcement today by the Company's JV partner of the successful completion of stage one of the Galactica Project development campaign, the Board of Helium One believe it is important that the Company has sufficient funds to maintain the drilling and development programme to maximise early revenue potential from the project, particularly in light of recent global events which have positively impacted the helium market dynamics.

The net proceeds of the Fundraise will therefore be utilised for this purpose as well as providing sufficient funds to maintain the Company's southern Rukwa Helium Project whilst the Company progresses the search for a strategic partner to advance this key project. Additionally, the net proceeds will be used for general working capital purposes.

Any additional proceeds raised from the Retail Offer will help facilitate an extended working capital runway.

Details of the Subscription and Retail Offer

The Fundraise Shares and the Retail Offer Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with Helium One's existing issued ordinary shares of no par value each (the "Ordinary Shares").

WRAP intends to conduct the Retail Offer on behalf of the Company on the terms outlined in a separate announcement to be made shortly. The Retail Offer is conditional on the Fundraise, but the Fundraise is not conditional on the Retail Offer. The Retail Offer will not be made available to investors outside the United Kingdom.

Admission and Settlement

Application will be made for the Fundraise Shares and the Retail Offer Shares to be admitted to trading ("Admission") on the AIM market of the London Stock Exchange ("AIM"). It is expected that Admission will take place at 8.00 a.m. (London time) on or around 31 March 2026 (or such later date as may be agreed between the Company and the subscribers).

The total number of Ordinary Shares subject to Admission will be confirmed following the completion of the Retail Offer, alongside the resultant total voting rights.

Notes to Editors

Helium One Global, the primary helium explorer in Tanzania with a 50% working interest in the Galactica-Pegasus helium development project in Colorado, USA. The Company holds helium licenses within two distinct helium project areas, across two continents and has the potential to become a strategic player in resolving a supply-constrained helium market.

The Company's flagship southern Rukwa Project is located within the southern Rukwa Rift Basin in south-west Tanzania. This project entering a full appraisal and development stage following the success of the 2023/24 exploration drilling campaign, which proved a helium discovery at Itumbula West-1 and, following an extended well test ("EWT"), successfully flowed 5.5% helium continually to surface in Q3 2024.

Following the success of the EWT, the Company filed a Mining Licence ("ML") application with the Tanzania Mining Commission in September 2024 and the 480km² ML was formally awarded to the Company in July 2025.

The Company also owns a 50% working interest in the Galactica-Pegasus helium development project in Las Animas County, Colorado, USA. This project is operated by Blue Star Helium Ltd (ASX: BNL) and successfully completed a six well development drilling campaign in H1 2025. The completion of the development programme is a key component of the broader Galactica-Pegasus development strategy; aimed at progressing the helium and CO₂ discoveries to near-term commercial production.

This programme has seen a systematic approach to developing the extensive Lyons Formation reservoir. The programme has delivered encouraging results, in line with expectations, consistently encountering good helium (up to 3.3% He) and CO2 concentrations in the target formation and demonstrating promising flow potential. The initial Galactica wells were tied into first gas in Q4 2025, with further wells coming onstream in 2026 for both helium and CO2 production.
