Completion of Acquisition of the Keyes Helium Complex

Helix Exploration PLC (AIM: HEX, OTCQB: HEXFF), the US based helium production and liquefaction company, is pleased to announce the completion of the acquisition of the Keyes helium complex ("Keyes Helium Complex").

On 2 July 2026, the Company announced it had entered into a conditional share purchase agreement to acquire the Keyes Helium Complex, a strategically located helium purification and liquefaction facility in Oklahoma, for aggregate consideration of US$11 million ("Acquisition"). The Acquisition enables Helix to capture the full margin from wellhead to liquid delivery, positioning the Company as an independent, multi-source US liquefier with both its own production and liquefaction infrastructure.

Bo Sears, Chief Executive Officer of Helix, commented: "The completion of the Keyes Helium Complex acquisition is a defining milestone for Helix. It transforms our business from a helium producer into a fully integrated helium company, giving us the rare ability to control the value chain from production through to liquefaction. We have acquired a high-quality, cash-generative strategic asset at a substantial discount to replacement cost, with significant expansion potential and infrastructure that would be exceptionally difficult to replicate today. As one of only a handful of helium liquefaction facilities in the United States, the Keyes Helium Complex positions Helix at the centre of an evolving North American helium market and provides a strong platform to accelerate growth, enhance margins and create long-term value for our shareholders."

Notes to Editors

Helix Exploration PLC is a US based helium production and liquefaction company listed on the London Stock Exchange (LSE: HEX), with operations spanning the helium value chain from production through to liquefaction. Its flagship Rudyard Project in Montana is the state's first producing helium field, with three stacked helium-bearing reservoirs in a proven geological setting and an initial four wells delivering commercial helium flow rates. Production commenced in February 2026 through an on-site PSA processing facility.

Following the acquisition of the Keyes Helium Complex in Oklahoma, one of only six operational helium liquefaction facilities in the United States, Helix has become an independent US helium producer owning both upstream production and liquefaction infrastructure. The acquisition positions the Company to capture greater value across the supply chain, process both its own and third-party helium, and support the growing North American helium market with flexible, independent liquefaction capacity.

Helix's assets are characterised by low-cost production, established infrastructure, significant expansion potential and a strategy focused on building a fully integrated helium business capable of delivering sustainable long-term growth.
