ASP Isotopes (ASPI) reported first-half 2026 revenue of $9.3M, up from $2.3M a year earlier, driven by specialist isotopes, new U.S. radiopharmacy operations, and helium and LNG activity tied to the Renergen acquisition, plus TerraPower collaboration revenue.

ASP Isotopes said Tetra4, a subsidiary of Renergen, signed a five-year take-or-pay LNG offtake for its Virginia Gas Project in South Africa. The deal covers about 10% of Phase 1 capacity, priced above $16 per GJ, and supports revenue certainty. Phase 1 targets ~2,500 GJ/day LNG and ~70 Mcf/day helium, with operations in Q3 2026; Phase 1 revenue could exceed $27M annually.
