Tharisa launches Level 1 American Depositary Receipt programme

Tharisa, the mining, metals, and innovation company dual-listed on the Johannesburg and London stock exchanges, has completed the establishment of a Level 1 American Depositary Receipt (ADR) programme (the Programme), with J.P. Morgan appointed as the depositary bank.

The Programme is effective from 8 June 2026 under the ticker symbol THARY.

The ADR Programme will enable US-based investors to gain exposure to Tharisa through USD denominated ADRs trading in the United States of America (USA) over-the-counter (OTC) market. Each Tharisa ADR will represent ten ordinary shares of the Company. The underlying ordinary shares will continue to trade on the Johannesburg Stock Exchange (JSE: THA) and the London Stock Exchange (LSE: THS).

STRATEGIC RATIONALE

The ADR Programme is part of Tharisa's broader strategy to enhance accessibility of its securities to international investors, with a particular focus on the USA where interest in critical and strategic minerals continues to grow. Platinum group metals (PGMs) and chrome as the core commodities mined by Tharisa, are recognised as critical minerals in the USA and other major economies, and as such attract increasing attention from investors seeking exposure to the energy transition, clean air technologies and future facing technologies including AI.

Phoevos Pouroulis, CEO of Tharisa, commented:

'The establishment of our ADR programme marks a meaningful step in broadening Tharisa's global investor reach. The United States is an attractive jurisdiction, and we are seeing significant interest in critical and strategic minerals, the very commodities at the heart of our business. All of the commodities we mine fall into both categories, and this programme gives US investors a simple, accessible and familiar mechanism through which to access our equity story. It is consistent with our strategy of enhancing optionality, improving liquidity and reaching the widest possible pool of institutional and retail investors who recognise the value of what we are building at Tharisa.'

IMPACT ON SHAREHOLDERS

The Programme has been registered with the United States Securities and Exchange Commission (SEC). As a Level 1 programme the Company is exempt from the ongoing registration and reporting requirements of the United States Securities Exchange Act of 1934, as amended. The establishment of the Programme does not affect the rights or entitlements of existing shareholders. No new ordinary shares are being issued and there is no dilution of existing shareholdings as a result of the Programme. Existing shareholders on the JSE and LSE registers are not required to take any action in connection with this announcement.
