KAISER ALUMINUM CORP

We have policies in place to identify, assess and manage potential risks and to continually review the procedures that we have designed and implemented to mitigate those risks. We believe that our board of directors provides effective oversight of the risk management function. Under its charter, the audit committee of our board of directors is responsible for discussing our risk management policies, including, without limitation, the steps taken and to be taken to monitor and control our major financial risk exposures. The audit committee also reviews risks relating to our information technology systems, including cybersecurity. The compensation committee of our board of directors is responsible for assessing risks associated with our compensation policies and incentivizing the conduct of our business in a manner consistent with our corporate values and implementing our clawback policies. The nominating and corporate governance committee of our board of directors is responsible for evaluating our corporate governance structure, reviewing our directors, managing board succession planning and reviewing and evaluating the succession planning of our CEO and other executive officers. The sustainability committee of our board of directors is responsible for overseeing certain sustainability-related risks, including overseeing our overall approach to sustainability principles and related disclosures, reviewing and evaluating our leadership and development training, and reviewing the diversity of our management and workforce and our approach to recruiting and retaining our employees in accordance with our corporate values. Our Executive Vice President and Chief Financial Officer, working with a committee of other members of senior management, oversees our climate-related risk management approach and report regularly to the sustainability committee and the full board of directors on such matters.

In addition, our full board of directors is actively engaged in the review and assessment of our risk management policies, conducts a comprehensive review at least annually during a regularly scheduled board meeting and routinely requests that specific risk-related items be included on board and committee meeting agendas. We also engage in an ongoing enterprise risk management process pursuant to which we formally identify, categorize and assess our risks and risk mitigation strategies and routinely update the audit committee and the full board of directors regarding this process.
