Rudyard – Extension of Helium Sales Arrangement

Helix Exploration PLC (AIM: HEX, OTCQB: HEXFF), the US-focused helium producer and liquefier, is pleased to announce an extension of its spot sales arrangement (the "Sales Arrangement") with an industrial gases group (the "Customer") for the supply of helium, once production re-commences at Rudyard, through to March 2027.

Highlights

• Six-month extension of the Sales Arrangement follows the initial three helium tube trailer sales to the Customer during Rudyard’s start-up phase representing Helix’s commercial debut in the helium market.
• ​100% of available helium volumes from Rudyard committed to the Customer through to March 2027, with the potential for longer-term and higher-volume arrangements to be agreed in due course, supporting the Board's strategy of developing a diversified route-to-market portfolio.
• Commercial terms remain confidential, including Customer identity and prices, in line with customary practice for helium offtake arrangements. The agreed pricing is significantly above the pricing assumptions used in the Company’s pre-IPO model.
• Continuous trailer rotation will facilitate helium sales, using a combination of Helix-leased and Customer-supplied tube trailers.
• Additional wells expected to be added through the ongoing production expansion programme.

Bo Sears, Chief Executive Officer, commented:

"Having demonstrated our capability as a supplier of high-grade helium to an important industrial gases group, we are pleased to convert a short-term arrangement into a longer-term spot sales agreement, taking advantage of strong helium demand. With a production expansion programme underway, we look forward to increasing sales volumes to the Customer over time.”

About Helix

From explorer to integrated US helium producer in just over two years.

Helix Exploration PLC (LSE: HEX) is a US-focused helium producer and liquefier building an integrated position across the helium value chain. Its flagship Rudyard Project in Montana commenced production in February 2026, with first commercial sales in July 2026. Production is currently subject to a regulatory pause requested by the MBOGC, as announced on 3 September 2026.

Helix is now expanding Rudyard through a drilling and processing capacity programme, supported by its own drilling rig, while the July 2026 acquisition of the Keyes Helium Complex in Oklahoma provides ownership of one of only six operational helium liquefaction facilities in the United States.

The combination of producing helium resources, owned drilling capability and liquefaction infrastructure gives Helix unique control across the value chain and creates multiple avenues for growth, including increased production, third-party processing and liquefaction.

Helix is focused on scaling a vertically integrated helium business positioned to serve the growing North American and global markets.
