ASPI ANNOUNCES THAT A SUBSIDIARY OF RENERGEN LIMITED HAS ENTERED INTO ITS
FIRST TAKE-OR-PAY CONTRACT FOR THE SUPPLY OF CONTAINED HELIUM TO BE
PRODUCED AT THE VIRGINIA GAS PROJECT IN SOUTH AFRICA
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.
DALLAS, June 23, 2026 (GLOBE NEWSWIRE) - ASP Isotopes Inc. (NASDAQ: ASPI) ("ASP Isotopes"
or the "Company"), an advanced materials company focused on developing technologies and
processes for the production of critical materials used in multiple industries, today announced that
Tetra4 Proprietary Limited, a subsidiary of Renergen Limited and the developer of the Virginia Gas
Project, has entered into its first contract for the sale of liquid helium to be produced at the Virginia Gas
Project in the Free State, South Africa.
"After receiving numerous enquiries, our team recently spent time meeting customers in Asia where
there is a clear urgent need for an additional supplier of helium," said Paul Mann, Executive Chairman
and Chief Executive Officer of ASP Isotopes. "We look forward to completing the construction of
Phase 1 and starting to supply customers at a point in time when geopolitical issues have greatly
constricted the supply of this critical material."
The helium sale and purchase agreement is a five-year, take-or-pay contract with an Asian industrial
gases company at an initial base price per unit of greater than $600/MCF of contained helium, on an
all-in plant-gate basis, and represents approximately 15% of the project's expected Phase 1 nameplate
capacity. Phase 1 is expected to produce approximately 2,500 GJ/day of liquefied natural gas (LNG)
and approximately 70 MCF/day of liquid helium, with commercial production expected to commence
during the third quarter of 2026.
The Company is in active discussions with additional potential customers regarding offtake of both LNG
and liquid helium from both Phase 1 and Phase 2. The Company expects to complete contracting for
the offtake of expected Phase 1 volumes during the third quarter of 2026 and commence contracting
for a significant portion of expected Phase 2 volumes during the second half of 2026.
Operational Progress at the Virginia Gas Project
Since restarting operations in April 2025 — following bridge loan funding provided by ASP Isotopes
prior to the completion of the Renergen acquisition — the project has advanced materially across drilling
execution, gas production and plant readiness. The drilling program for Phase 1 of the Virginia Gas
Project achieved its required cumulative nameplate flow rate in March 2026. The remaining activities to
ramp up production to full capacity are now primarily engineering-oriented tasks with considerably fewer
uncertainties.
The recent drilling success is primarily attributable to the post-restart engagement of Kinley Exploration,
a U.S.-based company with expertise in independent exploration, well design, drilling and reservoir
modelling, to support seismic interpretation, reservoir modelling, well placement, well design and drilling
execution. Kinley's involvement has optimised current drilling approaches and has bolstered target
selection and well design. Recent drilling successes have seen gas flow rates up to 16 times that
achieved in some of the earlier wells.
During the next few months, the team plans to tie in the new wells with the processing plant. Once all
the wells have been completed and made production ready with tie-in to the gas network, the total flow
is expected to meet or exceed Phase 1's nameplate capacity. Production is expected to be increased
to match our customers' demand and ability to off-take the product.
Helium Market: A Critical Supply Disruption
Following the acquisition of Renergen, the Company is focused on the long-term development of helium
production at the Virginia Gas Project. With the targeted completion of Phase 1 of the Virginia Gas
Project during the third quarter of 2026 and the commencement of Phase 2 thereafter, the Company
plans to emerge as a significant producer of liquid helium, and a vital contributor to diversifying
worldwide helium supply.
The helium market is characterized by a concentrated group of producers, many of which are located
in geopolitically sensitive areas, such as Qatar and Russia, making it vulnerable to supply disruptions.
Qatar is responsible for more than 25% of the world's liquid helium production. The recent closure of
the Strait of Hormuz has put immediate and considerable pressure on the supply of this unique critical
material. Reports from local press in Qatar indicate that Ras Laffan, Qatar's primary LNG and liquid
helium facility, has sustained damage from drone and missile strikes. The duration of this supply
restriction remains uncertain. Early indications are that repairs may take anywhere from several weeks
to several months, but until the full extent of the damage has been assessed, helium markets are likely
to remain squeezed.
According to the U.S. Geological Survey, in 2025 Qatar supplied approximately 2.3bn scf of helium,
which is almost a third of global supply. Whilst the Strait of Hormuz remains closed or restricted, the
annual deficit of helium supply to the world is expected to increase and result in upward pressure on
pricing. According to media reports, around 17% of total LNG export capacity from Qatar has been
affected with repairs expected for around three to five years, which is likely to translate to a similar
reduction in long-term helium supply from the nation. The availability of iso-containers, which are used
to transport the helium, is likely to be constrained as they are held up within the Persian Gulf, which
may significantly impact supply chains in other jurisdictions due to the reduction in the number of helium
iso-containers in circulation.
In April 2026, Russia introduced export controls on helium to maintain a stable supply to its domestic
market and certain Asian economic partners. Russia is the world's third-largest helium producer behind
Qatar and the United States, with an approximate 20% global market share, according to 2025 U.S.
Geological Survey data. We believe these export controls are likely to show their effect on the global
market during the second half of 2026.
The world has experienced several previous helium supply crises during the past 20 years, during which
market prices have reached in excess of $1,000/MCF. The Virginia Gas Project has historically
assumed an average selling price significantly below such levels in its planning, based on a mix of long-
term contracts and spot sales, with spot sales generally trading at a substantial premium to contracted
rates. South Africa remains geopolitically neutral, hence the conditional funding support from the U.S.
government, which we believe makes the Company's project one of the leading candidates for key
industries to diversify their critical helium supplies. The recent events in the Middle East have also had
a material impact on global LNG prices.
Phase 1 and Phase 2 Production Targets
Phase 1 is expected to produce approximately 2,500 GJ/day of LNG and approximately 70 MCF/day of
liquid helium. Phase 2, which carries a 44-month build timeline after the expected completion of
Phase 1, is targeted to scale production to about 34,000 GJ/day of LNG and 900 MCF/day of liquid
helium.
