Petra Diamonds Audit Delay Could Trigger Trading Suspension

(IDEX Online) - Trading in Petra Diamonds shares is likely to be suspended next week as it struggles to complete its annual audit, just weeks after launching a strategic review that could lead to the sale of its remaining mine or the entire company.

The London-listed miner announced on October 22 that it would miss the October 31 deadline for publishing its audited financial statements for the year ended June 30, 2026.

It expects its shares to be suspended from trading at 7:30 a.m. UK time on November 2, with no certainty about when trading will resume.

"The Group audit remains in progress, with additional time required to complete outstanding component and Group audit procedures, finalise the consolidated financial statements and complete the necessary audit reviews," Petra said in its announcement.

The company said it was working with its auditors to publish the annual financial report "as soon as practicable." It also warned that the delay was likely to affect the usual timing of its annual general meeting.

The suspension is the latest setback for a miner whose financial position has deteriorated amid falling diamond prices, mounting debt and the loss of a substantial part of its production base.

On October 1, Petra announced a strategic review after consulting key stakeholders, including its first- and second-lien creditors. The review is intended to address the company's near-term liquidity requirements and includes the possibility of selling assets.

Four days later, on October 5, Petra appointed South African corporate finance adviser Questco Corporate Advisory to manage the process and invite expressions of interest from potential investors and buyers.

Petra's net debt was $322 million at June 30, 2026, up from $298 million three months earlier.

The crisis has been compounded by the collapse of its Finsch operation in South Africa. The mine entered business rescue on May 29, and production was suspended in June after falling rough-diamond prices and a stronger rand made its predominantly smaller stones uneconomic.

In August, Finsch creditors approved a plan to sell the mine's assets after business-rescue practitioners failed to identify a viable way to restart operations. Finsch had accounted for about 34% of Petra's revenue in fiscal 2025.

Petra had already sold Koffiefontein in South Africa to Stargems Group in October 2024 and completed the sale of its Williamson mine in Tanzania in May 2025. The loss of Finsch leaves the Cullinan mine in South Africa as its sole producing operation.

Cullinan is a major asset, famous for producing the 3,106-carat Cullinan Diamond and other exceptional stones. Petra says the mine could continue operating into the late 2040s, and its potential to produce large and high-value diamonds could make it attractive to a buyer.

But the mine also requires substantial investment, while Petra's debt and wider financial obligations complicate the prospect of retaining it. A sale could provide a route to resolving the company's liquidity problems, although the proceeds and their distribution would depend on the terms of any transaction and the claims of creditors.

Petra's difficulties reflect the prolonged downturn in the natural diamond market, which has particularly affected producers of smaller rough stones. Its financial pressures have persisted despite earlier refinancing measures and efforts to reduce costs and capital spending.
