AVANTI HELIUM SIGNS STRATEGIC NON-BINDING TERM SHEET TO FAST-TRACK SWEETGRASS HELIUM RECOVERY PLANT AND HELIUM SALES EXPANSION

Avanti Helium Corp. has signed a non-binding term sheet with a publicly traded United States-based company (the partner) for the funding, construction, ownership and operation of its Sweetgrass helium recovery plant in Montana. Upon completion of the facility, the partner will purchase the remaining available helium production for a term of five years.

Once final documents are completed, this agreement will mark a pivotal milestone in Avanti's journey toward first production and monetization of its flagship Sweetgrass asset. It will unlock access to third party capital, accelerate project timelines and expand commercial offtake volumes to 100 per cent of production.

Key highlights of the non-binding term sheet

Turnkey helium plant development

The partner will finance, build, own and operate the Sweetgrass helium recovery unit (HRU), with initial design capacity of 10 million cubic feet per day (MMcf/d), scalable to 15 MMcf/d based on production performance and reservoir analysis. This capital-efficient structure enables Avanti to remain focused on high-value exploration and development while leveraging the partner's infrastructure expertise.

Capital-light operating model

Upon commissioning, Avanti will pay the partner a monthly fee based on a mutually agreed return on deployed capital. This model provides operational certainty and preserves shareholder capital by avoiding significant upfront capital expenditures.

Pipeline integration option

The partner also holds an option to acquire Avanti's previously constructed Sweetgrass pipeline infrastructure, which connects its producing wells to the HRU site-streamlining operations and enhancing alignment between upstream and midstream functions.

Expanded offtake footprint

The term sheet includes provisions for the partner to purchase all currently uncontracted helium volumes from the Sweetgrass facility under a five-year offtake agreement, with pricing subject to review after year three. This creates a robust commercial foundation for full-field monetization and cash flow predictability.

This new arrangement supersedes a previously announced midstream partnership, which has been amicably terminated by mutual agreement. Avanti thanks the former partner for its collaboration and wishes them continued success.

Positioning for 2026 production

With the term sheet in place, Avanti and the partner are now advancing toward definitive agreements, expected in the coming weeks. Once finalized, this transaction will provide the company with a clear and fully financed path to production and revenue generation in 2026.

"This agreement represents a transformational step forward for Avanti," said Chris Bakker, chief executive officer of Avanti Helium. "By aligning with a well-capitalized, technically capable partner, we're not only accelerating our path to production and cash flow, but doing so with maximum benefit to our shareholders. This structure enables flexibility and scalability while preserving upside in a helium market that continues to strengthen. As the global supply chain rebalances and U.S. demand continues to rise, we believe Avanti is ideally positioned to become a key North American supplier."

Additional project updates -- including progress on definitive documentation, plant commissioning milestones and commercialization timelines -- will be shared in the weeks ahead.
