Rules of Conduct and Meeting Procedures for the Annual Meeting of Shareholders

Welcome to the 2023 Annual Meeting of Shareholders (the "Annual Meeting") of Howmet Aerospace Inc. (the "Company"). In the interest of an orderly and productive meeting, we ask that you abide by the following rules of conduct and meeting procedures:

1. The Annual Meeting will follow the agenda provided on the Annual Meeting website.
2. The only business matters to be conducted at the Annual Meeting are the matters set forth in the Notice of 2023 Annual Meeting of Shareholders and the 2023 Proxy Statement. Because we did not receive notice in accordance with our By-Laws of any additional matters to be considered, no other proposals or nominations may be introduced at the meeting.
3. The shareholder proponent (or representative) will have three minutes to present Proposal 5. As determined by the Chairman's or the Secretary's discretion, the Company may limit the shareholder proponent's allotted speaking time in the event the shareholder proponent's remarks are unrelated to Proposal 5 or derogatory to the Company.
4. Only shareholders as of the close of business on March 21, 2023, the record date for voting at the Annual Meeting, or their duly authorized proxies, are entitled to submit questions and vote at the Annual Meeting. Shareholders will need the 16-digit control number located on their Notice or proxy card to submit questions and vote.
5. If you have already voted your shares, your vote has been received and there is no need to vote again, unless you wish to revoke or change your vote. If you have not voted, please do so online at www.virtualshareholdermeeting.com/HWM2023before the close of the polls.
6. We welcome questions from shareholders. Shareholders have an opportunity to submit written questions immediately before and during the Annual Meeting. To submit a written question, once you are logged into the virtual meeting, type your question into the "Ask a Question" field box on the Annual Meeting website, then click "Submit".

6. To allow us to answer questions from as many shareholders as possible, we ask that you please limit yourself to one question per shareholder. We will do our best to answer as many questions pertinent to the Annual Meeting as we can during the live question and answer session. Questions from multiple shareholders on the same topic or that are otherwise related may be grouped, summarized and answered together.
