Quantum Helium Limited

("Quantum" or the "Company")

£5 Million Institutional Placing Positions Quantum for Next Phase of Growth

Quantum Helium Limited (AIM: QHE) is pleased to announce it has today raised £5 million (before expenses) by way of a conditional placing of 16,666,666,667 new ordinary shares (the "Placing Shares") at a price of 0.03 pence per share (the "Placing Price") (the "Placing").

The Placing was arranged by OAK Securities and was undertaken with a number of institutional investors who approached the Company, reflecting growing interest in Quantum's asset base and the strategic importance of domestic US helium supply.

Highlights

·      £5 million institutional placing

·      Cornerstoned by institutional investors following inbound demand

·      Validates the strength of Quantum's helium portfolio and US strategic positioning

·      Funding supports the next phase of development at Sagebrush and Coyote Wash

·      Multiple near-term catalysts, including results from the Company's extended production test at Sagebrush

·      Strengthened balance sheet and cash resources positions the Company well for next phase of growth

Background to the Placing

The Company has received increasing inbound interest from institutional investors in recent months, driven by the scale and quality of its helium portfolio and the growing strategic importance of helium as a critical commodity.

Helium plays an essential role in a wide range of high-value industries, including semiconductor manufacturing, AI infrastructure, medical imaging and advanced manufacturing, with demand continuing to increase.

At the same time, global helium supply remains constrained, with recent geopolitical developments, including disruptions in the Middle East, highlighting the importance of secure and domestic supply chains. This backdrop has resulted in increased investor focus on US-based helium development opportunities.

Quantum believes it is well positioned within this environment, with a portfolio of helium assets located in a proven US helium fairway and a clear pathway towards development and production.

Use of Funds

Proceeds from the Placing will be used to:

·      Advance development planning and engineering at the Sagebrush Project

·      Progress permitting, planning and progressing to drill-ready targets at Coyote Wash (100% owned)

·      Fund well planning, long-lead items and infrastructure design at the Company's Sagebrush and Coyote Wash projects

·      Support ongoing technical work, including seismic interpretation and subsurface modelling

·      Provide additional working capital and financial flexibility

The Company's extended production test at the Sagebrush-1 well which remains the key near-term operational milestone is being funded from existing cash resources.

Current Operations

As announced on 16 April 2026, the extended production test at the Sagebrush-1 well is progressing well, with operations advancing in line with expectations.

The next phase of operations will focus on the perforation and testing of the first of two zones in the Leadville Formation. The Lower Leadville will be tested first, followed by a test of the upper Leadville where the DST was previously run. Perforations are scheduled to start this coming week.

The testing programme is designed to evaluate flow characteristics and confirm historical helium concentrations, including the previously reported 2.76% helium, and represents a critical step towards converting resources into reserves and advancing towards commercial development.

The Company expects a number of significant operational updates in the coming weeks as testing progresses through this key phase.

Carl Dumbrell, Chairman of Quantum Helium, said: "This is a very strong outcome for the Company and we are pleased to have secured the support of a number of high-quality institutional investors who recognised the strength of our asset base and the opportunity we are developing.

The Placing reflects increasing awareness of the strategic importance of helium, particularly in the United States, where there is a growing need for secure and domestic supply. Recent global events have further highlighted supply constraints, and we believe Quantum is well positioned to play a role in addressing this.

Importantly, this funding places the Company in the strongest financial position it has ever been in and allows us to accelerate our development plans while maintaining momentum across our operations.

We look forward to delivering on the significant milestones ahead and continuing to build value for shareholders."

Quantum Chief Executive, Howard McLaughlin, added: "As outlined in our recent operational update, the extended production test program at Sagebrush-1 is progressing well and represents a major step towards unlocking the commercial potential of this project.

We are particularly excited about the upcoming perforation of the Lower Leadville Formation, which is expected to provide critical data on helium concentrations and flow rates. This will build on the historic results and further strengthen our understanding of the reservoir.

With this successful placing, we are now fully funded to execute our broader work programme across both Sagebrush and Coyote Wash. We have a number of important and exciting milestones ahead and remain confident in the outcome of the extended production test.

Our focus is firmly on progressing our projects towards commercialisation and establishing Quantum as a leading helium developer in the United States.

Additional Information

Quantum Helium has appointed OAK Securities (a trading name of Merlin Partners LLP), to act as the Company's exclusive bookrunner and placement agent in connection with the Placing. Subject to and conditional on Admission, OAK Securities will be paid an annual broker retainer of £50,000 payable in cash, a one-off corporate advisory fee of £15,000 payable in cash, a cash commission in an amount equal to six per cent (6.0%) of the gross proceeds raised pursuant to the Placing.  The Company will also issue OAK Securities warrants (the "Broker Warrants") to subscribe for 6.0% of the number of Placing Shares placed in the Placing, with such Broker Warrants being exercisable at a price per share equal to the Issue Price for 3 years from the date of the closing of the Placing. 

The Placing Shares, when issued and fully paid, will rank pari passu in all respects with the existing Common Shares in issue and therefore will rank equally for all dividends or other distributions declared, made or paid after the issue of the new Placing Shares.

Admission to AIM and Total Voting Rights

The Placing is conditional, inter alia, upon the Placing Shares being admitted to trading on AIM. Application has been made to the London Stock Exchange for the Placing Shares, which will rank pari passu with the Company's existing issued ordinary shares, to be admitted to trading on AIM and dealings are expected to commence at 8:00 a.m. on or around 23 April 2026.

Following the issue of the Placing Shares, the Company's total voting rights will comprise 49,985,396,722 Ordinary Shares of no par value, and the Company does not hold any shares in treasury. The above figure may therefore be used by shareholders as the denominator for the calculations by which they will determine whether they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the Companies' Articles.
