Tetra4, a subsidiary of Renergen and the developer of the Virginia Gas Project, has entered into its first take-or-pay contract to supply contained helium to an Asian industrial gases company, establishing a multi-year contracted cash flow supporting Phase 1 commercial operations, which remain targeted for the third quarter of 2026.

The helium sale and purchase agreement, which is a five-year take-or-pay contract, is priced at greater than $600/MCF of contained helium.

The Company is in discussions with multiple other potential customers and expects to complete contracting for Phase 1 volumes of up to 70 MCF/day of helium during the third quarter of 2026.

The Company is expecting to start construction on Phase 2 during 2H 2026. Phase 2 is approximately 13 times the size of Phase 1 and is expected to benefit from Tetra4’s conditional approval for up to $750 million of senior debt financing, comprised of up to $500 million from the U.S. DFC and up to $250 million from Standard Bank.
