              <p>PITTSBURGH--(BUSINESS WIRE)--May 4, 2023--Arconic Corporation (NYSE: ARNC) (&#8220;Arconic&#8221; or the &#8220;Company&#8221;) announced today that it has entered into a definitive agreement to be acquired by funds managed by affiliates of Apollo Global
                Management, Inc. (NYSE: APO) (&#8220;Apollo&#8221;), in an all-cash transaction that values the Company at an enterprise value of approximately $5.2 billion. The transaction includes a minority investment from funds managed by affiliates of Irenic
                Capital Management (&#8220;Irenic&#8221;). </p>
              <p> The agreement provides that Arconic shareholders will receive $30.00 per share in cash, which represents a premium of approximately 36% to the Company's undisturbed closing stock price on February 27, 2023. Upon completion of the
                transaction, Arconic's shares will no longer trade on the New York Stock Exchange, and Arconic will become a private company. </p>
              <p> &#8220;This transaction represents a realization of value for Arconic shareholders at a meaningful premium and enables the Company to execute its long-term strategic vision. We are pleased to reach this agreement with Apollo,&#8221; said Fritz
                Henderson, Chairman of the Arconic Board of Directors. &#8220;The Board decided to approve this transaction after thorough and thoughtful review of a range of value creation opportunities for shareholders.&#8221; </p>

                significant potential for growth across the markets we serve positions us to deliver substantial value to our customers and the end users of our products. This transaction will provide Arconic with the backing of one of the world&#8217;s premier
                investment firms and will allow us to leverage Apollo&#8217;s industry expertise and relationships to pursue our long-term strategic goals. I look forward to working with their team to create opportunities for our employees and provide value to
                our customers.&#8221; </p>
              <p> &#8220;Arconic&#8217;s talented management team and employees operate a set of premier global assets serving markets that are growing. We are committed to investing significant capital in the Company to secure its competitive position and world-class
                product offering to continue building on Arconic&#8217;s journey,&#8221; said Gareth Turner, Partner at Apollo Global Management. </p>
