REPORTING SCOPE AND BOUNDARY

Our 2022 IAR provides a detailed view of Gold Fields for the financial year ended 31 December 2022. It reflects on Gold Fields' financial and non-financial performance against our three strategic pillars, and how this created, preserved or eroded value for our key stakeholders – governments, employees, business partners, capital providers and host communities. Our financial reporting boundary includes the financial performance of our subsidiaries, joint ventures (JVs) and investments. It includes material information relating to our nine operations and one project in Australia, South Africa, Ghana (including our Asanko JV), Chile and Peru. We also include any material events after year-end and up to the Board approval date of 30 March 2023. We detail our geographical footprint where we operate.

The term "attributable" as it relates to production refers to 100% of our mines and projects except for Gruyere (50%), South Deep (96.43%), Damang (90%), Tarkwa (90%), Asanko (45% equity share), and Cerro Corona (99.5%). The term "attributable" as it relates to Mineral Reserves and Mineral Resources refers to 100% of our mines and projects, as well as Far Southeast (FSE) (40%), Gruyere (50%), Damang (90%), Tarkwa (90%), Asanko (45%) and Cerro Corona (99.5%). The exception is attributable Mineral Reserves and Mineral Resources at South Deep (90.5%). The term "managed" relating to production and Mineral Reserves and Mineral Resources refers to 100% of our mines and projects, as well as FSE (40%), Gruyere (50%) and Asanko (50%). The net debt:EBITDA ratios mentioned in this report refer to adjusted EBITDA, while we present Group and mine All-in costs and All-in sustaining costs in terms of the original World Gold Council interpretation.

Non-financial data included in this IAR relates to our eight operating mines and excludes our non-managed Asanko JV and the Salares Norte project in Chile, unless stated otherwise. Socio-economic development spend includes spend by the South Deep trusts.

For 2022, we used average exchange rates of R16.37/US$1 and US$0.69/A$1
(2021: R14.79/US$1 and US$0.75/A$1; 2020: R16.38/US$1 and US$0.69/A$1). We used forecast exchange rates of R17.00/US$1 and US$0.70/A$1 for 2023.
