On September 30, 2020, the closing price of the Class B common stock on The NASDAQ Global Select Market was $28.01 per share. Includes shares acquired periodically pursuant to a dividend reinvestment program meeting the requirements of Rule 16a-11. These shares were withheld by ViacomCBS to satisfy tax liability incident to the settlement of, and delivery of the 128,027 shares underlying, the RSUs, and were not actually sold or otherwise disposed of in an open-market transaction. Initially granted as performance share units under the Viacom Inc. 2016 Long-Term Management Incentive Plan for no consideration. These RSUs vested on September 30, 2020 and were settled by delivery of a corresponding number of shares of Class B common stock. This number was previously shown as a holding of 128,027; it is adjusted here to reflect that 44,139 of the 128,027 shares were already included on Table 1, as permissible. /s/ Christa A.
