Prominent South African company in serious trouble

Renergen is set to report another loss for the first half of the 2026 financial year as its struggle to produce liquid helium profitably continues.

Renergen was founded in September 2014 and listed on the JSE in June 2015 as a special-purpose acquisition company.

Its principal asset is its 100% shareholding in Tetra4, which holds petroleum production rights in South Africa.

The company’s Virginia Gas Project is located in the Free State, approximately 250 km southwest of Johannesburg.

Its primary revenue source is liquefied natural gas, with prospects to generate revenue from liquid helium and discontinued operations of compressed natural gas.

On Monday, 22 September, Renergen informed shareholders that it expects its loss per share and headline loss per share to deepen by at least 20% for the six months through August 2025.

Renergen did not specify a range of expected losses. However, it said the 20% figure represents an increase of at least 9.15 cents per share compared to the prior period’s loss per share of 45.73 cents per share.

This means the company is set to report a net loss of at least R85.2 million for the six-month period.

The gas producer attributed this significant loss to several factors, including once-off transaction costs incurred as part of its proposed acquisition by ASP Isotopes.

ASP Isotopes is an advanced materials company listed on the NASDAQ and, more recently, the JSE.

The company announced its intention to acquire Renergen earlier this year. However, the deal still requires certain approvals before being finalised.

On Monday, 15 September, the companies announced that, while they remain optimistic about this deal reaching the finish line, they extended the deadline for fulfilment of conditions from 30 September 2025 to 28 November 2025.

Renergen also attributed its bigger loss to an increase in various costs, including depreciation expenses for its full Phase 1 plant and interest expenses.

This loss is nothing new for Renergen, which has yet to report any liquid helium sales, and has reported record losses year after year. 

It is also in deep financial trouble, having breached debt covenants on most of its debt. Since most of Renergen’s debt is securitised by the assets of the Tetra4 gas plant, the whole plant is at risk if further debt covenant breaches occur.

Since its latest financial reports, Renergen has R1.1 billion in debt and only R28 million cash in the bank.

Renergen’s full interim results for the six months ended 31 August 2025 are expected to be released on or about 30 October 2025.
