INTRODUCTION

2024 MATERIALITY ASSESSMENT

In 2024, U. S. Steel refreshed the materiality assessment that was conducted in 2022 and broadened our outreach to include input from more internal and external stakeholders.

We engaged more than 90 internal and 20 external stakeholders to assess and reprioritize material topics identified in 2022. We conducted interviews and surveys with leaders across U. S. Steel business lines and external stakeholders representing customers, suppliers, lenders and non-governmental organizations. The stakeholders rated the importance of sustainability and ESG topics to themselves and to other stakeholders, as well as to U. S. Steel’s corporate goals and strategy. In addition, stakeholders commented on the sustainability and ESG topics they expect to grow in importance in the short and medium terms.

The matrix shows our 16 material topics in relation to stakeholde importance. The nine bolded topics are our focus topics as of 2024. For more information on how we are integrating these topics into our short and long-term strategies, see our GRI 3-3 disclosure in the 2023 Sustainability Report PDF.

U. S. Steel will continue to engage with a variety of internal and external stakeholders to understand evolving perspectives around sustainability and ESG topics and risks and opportunities across our value chain. The insights gathered from this materiality refresh will continue to shape our sustainability strategy and enterprise risk management mitigation strategies going forward.
