Exhibit A:

The 10-for-1 forward stock split was effected by means of (i) a stock dividend of nine (9) shares of class A common stock, $0.001 par value per share, of the Issuer (the “Class A Common Stock”) on and in respect of each of the issued and outstanding shares of Class A Common Stock (the “Class A Stock Dividend”) as of August 1, 2024 (the “Record Date”) and (ii) a stock dividend of nine (9) shares of class B common stock, $0.001 par value per share, of the Issuer (the “Class B Common Stock”) on and in respect of each of the issued and outstanding shares of Class B Common Stock (the “Class B Stock Dividend” and, together with the Class A Stock Dividend, the “Stock Dividend”) as of the Record Date. The Stock Dividend resulted in proportionate adjustments to the number of shares of Class A Common Stock beneficially owned by the reporting person and issuable under equity awards beneficially owned by the reporting person, including shares underlying outstanding restricted stock units, performance stock units and stock options, and the exercise prices of the stock options beneficially owned by the reporting person.
