Petra Diamonds Faces $7.5 Million UK Tax Petition Amid Refinancing Pressure

Petra Diamonds is facing a £5.65 million ($7.5 million) UK corporation tax claim against an indirect subsidiary, adding pressure as the Africa-focused diamond producer works to strengthen its finances and refinance existing debt.

The winding-up petition was filed against Petra Diamonds UK Treasury (PDUK Treasury), a wholly owned indirect subsidiary, over corporation tax relating to the year ended 30 June 2025. The matter is scheduled to be heard in the UK High Court on 14 October.

According to Petra, the tax liability relates to interest income accrued on a receivable from another wholly owned subsidiary, Ealing Management Services. PDUK Treasury has not received the accrued interest.

Petra said the two companies involved are non-operating subsidiaries and do not own or operate its mining assets. As a result, the petition does not directly affect the company’s mining operations, although Petra is assessing whether it could have implications for its financing arrangements and ongoing refinancing discussions.

The development comes shortly after Petra announced a strategic review aimed at addressing its near-term cash requirements. The review followed discussions with key stakeholders, including first- and second-lien creditors, and could result in the sale of assets.

The review could potentially involve the Cullinan diamond mine near Pretoria, one of Petra’s key South African operations. Its Finsch mine in the Northern Cape is already being closed after business rescue practitioners determined there was no reasonable prospect of rescuing the operation.

Petra’s financial position has been affected by prolonged weakness in the natural diamond market and a stronger South African rand. Net debt increased to $322 million at the end of June, from $298 million three months earlier.

The company secured an additional $17.955 million working-capital facility from a senior lender in July and deferred approximately $6 million in cash interest payments until January 2027.

Petra’s financing arrangements also require the company to pursue refinancing discussions, with the objective of reaching non-binding commercial terms by the end of October.

The UK tax petition therefore comes at a sensitive point for Petra as it evaluates its asset portfolio and seeks additional financial flexibility. While the proceedings do not directly involve its operating mines, the company is assessing their potential implications for its wider financing structure and refinancing process.
