(1) Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement shall also cover any additional shares of the Registrant’s Class A common stock or Class B common stock that become issuable in respect of the securities identified in the above table by reason of any stock dividend, stock split, recapitalization, or other similar transaction effected without the Registrant’s receipt of consideration which results in an increase in the number of the outstanding shares of the Registrant’s Class A common stock or Class B common stock.

(2) Represents additional shares to be registered under the 2020 Equity Incentive Plan (“2020 EIP”) resulting from the annual 5% automatic increase in the number of authorized shares available for issuance under the 2020 EIP.

(5) Estimated in accordance with Rules 457(c) and 457(h) of the Securities Act solely for the purpose of calculating the registration fee. The proposed maximum offering price per share of $40.21 was computed by averaging the high and low prices of a share of Registrant’s common stock as reported on The Nasdaq Global Market on March 19, 2021, multiplied by 85%, which is the percentage of the trading price per share applicable to purchasers under the 2020 ESPP.
