Kaiser Aluminum Corp

##### Public Policy and Advocacy

###### We maintain strong and constructive working relationships with public officials, regulatory agencies, and non- governmental organizations in the communities where we operate. These relationships allow us to communicate our concerns and engage in meaningful dialogue with public officials and other key stakeholders about issues relevant to Kaiser Aluminum and to our industry. At each of our facilities, we collaborate with various regulatory agencies to consult on major capital projects that may require additional regulatory review and authorization.

###### Trade Association Memberships

We are active members of several industry organizations, trade associations, chambers of commerce, and other non-governmental organizations, including the Aluminum Association, the Metals Service Center Institute, the Can Manufacturers Institute, and the Aluminum Stewardship Initiative, as well as various local and state-level trade associations. These organizations foster collective innovation, facilitate the exchange of best practices, develop industry standards, and provide guidance on issues that might impact our business.

In 2022, our ESG Committee of the Board continued to engage with Senior Leadership and provide oversight on evaluating risks and opportunities - including climate-related risks and opportunities, talent development and health and safety – to support the Company's long-term growth and value creation for its stakeholders. The Board continues to provide effective risk management oversight and guidance on ESG-related initiatives that reinforce Kaiser's long-term sustainability strategy. [...] Our Board ESG Committee meets quarterly and oversees the execution of our ESG initiatives and strategies and provides guidance to our Senior Leadership Team (SLT) and ESG Task Force who devise and implement our ESG strategy. [...] Our climate strategy is advancing with direct oversight from our Board ESG Committee and our Senior Leadership Team with strategic and technical support led by our ESG Task Force. Our Senior Leadership Team and the ESG Task Force meet at least quarterly to discuss progress towards our sustainability strategy and initiatives, including climate and greenhouse gas emission reduction initiatives and our progress towards achieving our established goals and targets. Updates are provided on an ongoing basis to our Board ESG Committee, and our climate strategy is re-evaluated as determined necessary.
