Johannesburg, 1 June 2021. Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW - https://www.commodity-tv.com/ondemand/companies/profil/sibanye-stillwater-ltd/ ) advises that it will be implementing an on-market repurchase of up to, but not exceeding, 5% of its ordinary shares in issue as at 31 May 2021 (the “buyback program”).

The buyback program is consequential to the successful financial deleveraging and resumption of industry leading dividend payments by the Group during 2020 and is consistent with the strategic capital allocation framework approved by the Board in February 2021. The Group’s capital allocation framework for 2021 prioritises investing in operational sustainability, maintaining appropriate cash reserves, paying industry leading dividends and prudent debt management.

Commenting on the buyback, Neal Froneman CEO of Sibanye-Stillwater said: “The approval of the buyback program underpins our commitment to creating value for all stakeholders through disciplined adherence to our capital allocation framework and reflects the robust financial position and positive fundamental outlook for the Group.

The Board considers the repurchase of our undervalued shares in the market as the most appropriate and value enhancing allocation of surplus capital at this stage, to ensure ongoing delivery of superior returns to shareholders. The buyback program is complementary to and will not compromise our industry leading dividend or other capital allocation priorities.”

Further information regarding the buyback program:

The buyback program will be limited to a maximum of 147,700,000 ordinary shares, representing up to 5% of the total number of shares in issue, based on the number of ordinary shares in issue at 31 May 2021. The buyback program will be implemented between 2 June 2021 and 6 April 2022 (the “buyback period”), consequently, will include a Prohibited Period, as defined in the JSE Listings Requirements.

Any purchases of shares will be effected on the Johannesburg Stock Exchange and within certain pre-set parameters, in accordance with the Group’s general authority to repurchase shares granted by the Group’s shareholders at the annual general meeting on Tuesday, 25 May 2021, and in accordance with the applicable provisions of the South African Companies Act 71 of 2008, as amended, and the JSE Listings Requirements.

In accordance with paragraph 5.72(h) of the JSE Listings Requirements, Sibanye-Stillwater has appointed Morgan Stanley, as independent third party, to conduct the buyback programme, and Morgan Stanley will make investment decisions in relation to the Company's shares independently of, and uninfluenced by, the Company, during the buyback period. Any shares repurchased by the Company in terms of the buyback programme will be cancelled from the Company's issued share capital.

Ends.
