Sustainability Report 2025

Materiality and material issues

In line with our purpose and sustainability strategy, we take an integrated and comprehensive approach to materiality, working to understand the material impacts of our business on the external environment and our stakeholders, as well as the impacts of the external environment on the current and future financial sustainability of the business.

Every year, we conduct a comprehensive double-materiality assessment, supported by an independent third party, that considers our impacts, risks and opportunities.

The following definitions guide our process:

  • Impact materiality: we assessed whether the sustainability issue in question is material from an impact perspective, focusing on its actual or potential positive and negative impacts on people and/or the environment connected to us. This includes considering short and long-term impacts
  • Financial materiality: we assessed whether the sustainability issue is material from a financial perspective, ie whether it has the potential to influence our future cash flows or enterprise value in the short, medium and long term, even if these financial impacts may not currently be quantifiable.

Our process

We have adopted a four-stage process:

1

Desktop analysis

We analysed peer reporting, current and emerging disclosure standards and feedback from ratings agencies to determine a list of industry issues.

2

Stakeholder assessments

This year’s assessment included detailed interviews with 15 internal stakeholders (including seven members of our board) and seven external stakeholders (investors and analysts, media and an industry body). Interviewees were asked to raise issues they believed were material to both the company and its stakeholders and environment, today and in future. These discussions helped narrow the list of issues specifically related to Valterra Platinum. The list of issues identified was also aligned with our integrated risk assessment process.

3

Assessing materiality

In a materiality assessment workshop with our exco, members independently ranked the 26 issues identified through the desktop analysis and stakeholder assessments on an online platform. Members were asked to assess whether issues were material from both an impact and financial materiality perspective (defined alongside), the relevant timeframe (short, medium and long term) associated with the issue, and whether it presented a risk and/or opportunity.

4

Review and finalisation

The final list of material issues was considered by exco and the SEG committee. After reviewing the findings, the committee agreed that the identified issues should be included in the 2025 sustainability and integrated reports.

These matters have guided the content of this report and are referred to throughout.

Material issues for 2025

The issues identified in our materiality assessment are interdependent and dynamic, meaning they are often closely linked and evolve over time. While we have reported on the top 13 issues, we recognise that the remaining issues identified may also be important to the business. They continue to be closely monitored to ensure they are appropriately managed within our broader sustainability strategy, even where they are not an immediate focus.

The table summarises the outcome of our double-materiality assessment. For each material matter, we have indicated whether it is considered an impact or financial matter (or both), associated timeframes and whether it is a risk or opportunity. We have also indicated and where the matter is discussed in this report. While the matters are ranked, we recognise that their relative importance may change.
