Arconic to Be Acquiredby Apollo Funds Transaction Fact Sheet May 2023

$30 Per Share Sale Price $5.2B Enterprise Value1 Apollo to Acquire Arconic All Cash Acquisition Transaction Fact Sheet Based on total enterprise value, including total equity value plus assumption of net debt, pension, and OPEB (pension/OPEB tax adjusted at 1Q 2023 effective tax rate of 28.6%). Based on closing price of $22.13 on February 27, 2023. Based on midpoint of 2023E Adj. EBITDA guidance range of $650M – $700M. Arconic has not provided reconciliations of any forward-looking non-GAAP financial measures, such as adjusted EBITDA, to the most directly comparable GAAP financial measures because such reconciliations are not available without unreasonable efforts due to the variability and complexity with respect to the charges and other components excluded from the non-GAAP measures, such as the effects of metal price lag, foreign currency movements, gains or losses on sales of assets, taxes, and any future restructuring or impairment charges. These reconciling items are in addition to the inherent variability already included in the GAAP measures, which includes, but is not limited to, price/mix and volume. Arconic believes such reconciliations would imply a degree of precision that would be confusing or misleading to investors.
