 the GISTM. We will continue to refine and enhance the data inputs and estimates used in our modelling to generate more accurate and meaningful results that will help focus our activities in 2025 and beyond. – Extension of Value at Risk (VaR) analysis/financial risk: We advanced the Global VaR top-down risk assessment with more detailed financial risk modelling at a product group level. We have completed the assessment of our Iron Ore product group and have started work on the Aluminium product group and expect to complete this in 2025. In addition to asset damage, the product group level assessment also evaluates the impacts of business interruption on Group revenue. – Bottom-up risk assessments: Asset- level climate resilience assessments are advancing across all product groups as part of a broader multi-year program. In 2025, we plan to perform a comprehensive review of the methodologies and governance processes supporting climate risk management and resilience measures. This will focus on strengthening the integration of climate resilience analysis and planning into asset-level risk assessment frameworks and processes. – Water supply: In 2025, we will conduct 2 climate risk assessments on non- managed hydropower supply for the NZAS and Bell Bay aluminium smelters. We will also assess our water supply at our operations in Gladstone.

Climate-related governance The Board The Board has ultimate responsibility for our overall approach to climate change. This includes the oversight of climate-related risks, opportunities, strategy, projects, partnerships, physical resilience, engagement, reporting, and advocacy as per the Schedule of Matters.

The Board approves our overall strategy, policy positions, and climate disclosures within this report, delegating specific responsibilities to committees and the Chief Executive.

The CFO presents a performance report, including a dashboard of KPIs and a detailed decarbonisation scorecard covering, but not limited to, operational emissions, offsets, abatement projects and Scope 3 emissions. In the past 12 months, the board agendas have included climate-related items, such as discussions on the Boyne Smelter repowering solutions and NZAS electricity arrangements. The Board balances environmental goals with financial and social implications. For example, we
