Result of Retail Offer

Helix Exploration PLC (AIM: HEX, OTCQB: HEXFF), the US based helium producer, announced on 2 July 2026 the launch of a fundraising comprising a Placing in conjunction with a Retail Offer (the "Fundraising").

The Company is pleased to announce that the Retail Offer, which was significantly oversubscribed, successfully completed and closed at 10 a.m. on 3 July 2026. As such, the Company has conditionally raised gross proceeds of approximately £1.6 million in the Retail Offer through the issue of 7,272,727 new Ordinary Shares at the Issue Price of 22 pence per share.

Following the close of the Retail Offer, the Company has conditionally raised gross proceeds of £17.6 million at the Issue Price pursuant to the Fundraising. The Company will therefore be required to issue and allot a total of 80,000,000 new Ordinary Shares to satisfy the Fundraising. In addition, the Company will issue 1,300,461 new Ordinary Shares pursuant to the TSD Acquisition and 2,023,280 new Ordinary Shares pursuant to the SPA.

Together, the 80,000,000 new Ordinary Shares to be issued pursuant to the Fundraising, the 1,300,461 new Ordinary Shares to be issued pursuant to the TSD Acquisition and the 2,023,280 new Ordinary Shares to be issued pursuant to the SPA comprise, in aggregate, 83,323,741 new Ordinary Shares (the "New Ordinary Shares").

Bo Sears, Chief Executive Officer of Helix, commented: "We are encouraged to see the demand to participate in the Retail Offer considerably exceeding capacity. We appreciate the confidence of all participants who evidently recognise the opportunity for Helix to establish an integrated position that spans the helium value chain, from reserves in the ground through to liquefaction - a combination that few independents have ever held."

Admission and Total Voting Rights

Application will be made to the London Stock Exchange for the 83,323,741 New Ordinary Shares to be admitted to trading on AIM. Admission is expected to take place and dealings in the New Ordinary Shares are expected to commence at 8.00 a.m. on or around 7 July 2026, at which time it is also expected that the New Ordinary Shares will be enabled for settlement in CREST.

Immediately following Admission, the issued share capital of the Company is expected to comprise 278,826,141 Ordinary Shares. Each Ordinary Share has one voting right and no Ordinary Shares are held in treasury. From Admission, this figure may be used by Shareholders as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.
