Quantum Helium Limited

("Quantum" or the "Company")

Proposed Share Consolidation

&

Notice of Extraordinary General Meeting

Quantum Helium Limited (AIM: QHE) announces that the Company is proposing to implement a consolidation of its ordinary share capital on the basis of 1 new ordinary share for every 100 existing ordinary shares held (the "Share Consolidation").

The Company has today posted a Notice of Extraordinary General Meeting ("EGM") to shareholders in connection with the proposed Share Consolidation.

The EGM will be held at 5:00 p.m. (AEST) on Wednesday, 01 July 2026 at Level 4, 55 York Street, Sydney NSW 2000, Australia.

The Board believes that the proposed Share Consolidation is appropriate at this stage of the Company's development and will better position the Company in the public markets, particularly in the context of the Admission of its shares to trading on AIM.

If approved, shareholders on the register at the record date will exchange every 100 existing ordinary shares for 1 new ordinary share. The proportion of the issued share capital of the Company held by each shareholder following the Share Consolidation will, save for fractional entitlements and subject to adjustments relating to warrants and other convertible securities, remain unchanged.

Background to and reasons for the proposed Share Consolidation

As at the date of this announcement, the Company has 49,985,396,722 ordinary shares in issue.

The Directors believe that the current number of shares in issue and the associated low share price level are not optimal for the Company at its current stage of development.

The Board believes that the proposed Share Consolidation will:

• Achieve a more appropriate share price level;

• Improve the perception of the Company among institutional investors;

• Reduce share price volatility; and

• Better align the Company with AIM market expectations.

The Directors believe that the Share Consolidation will assist in providing a capital structure more appropriate for a company of Quantum's scale and stage of development while maintaining shareholder proportional ownership.

Effect of the Share Consolidation

If the Resolution is approved at the EGM:

• Every 100 existing ordinary shares will be consolidated into 1 new ordinary share;

• The number of warrants and other convertible securities on issue, together with the applicable exercise prices, will be adjusted on a 100:1 basis in accordance with their governing terms;

• The issued share capital of the Company will reduce from 49,985,396,722 ordinary shares to approximately 499,853,967 ordinary shares; and

• There will be no change to the underlying market capitalisation of the Company as a result of the Share Consolidation.

Fractional Entitlements

Fractional entitlements arising from the Share Consolidation will not be issued. The Directors will determine the treatment of any fractional entitlements in a manner they consider appropriate.

Admission to AIM

Application will be made for the consolidated ordinary shares to be admitted to trading on AIM.

Admission is expected to occur on or around 3 July 2026.

Expected Timetable of Principal Events

Total Voting Rights

Following completion of the Share Consolidation, the Company is expected to have approximately 499,853,967 ordinary shares in issue, each carrying one voting right.

Board Recommendation

The Directors unanimously recommend that shareholders vote in favour of the Resolution to be proposed at the EGM.

A copy of the Notice of EGM will shortly be available on the Company's website at www.quantum-helium.com.

The consolidated shares will trade under a new ISIN which will be advised to shareholders via RNS once received
