2/24/2018 S-1 Table of Contents PRINCIPAL AND SELLING STOCKHOLDERS The following table sets forth certain information with respect to the beneficial ownership of our capital stock as of January 31, 2018, and as adjusted to reflect the sale of our common stock offered by us and the selling stockholders in this offering assuming no exercise of the underwriters’ option to purchase additional shares of our common stock from us and the selling stockholders, for: • each of our named executive officers; • each of our directors; • all of our current directors and executive officers as a group; • each person known by us to be the beneficial owner of more than 5% of the outstanding shares of each of our Class A common stock and Class B common stock; and • all selling stockholders. We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Sections 13(d) and 13(g) of the Securities Act. We have based our calculation of the percentage of beneficial ownership prior to this offering on 40,482,669 shares of our Class A common stock, 523,399,452 shares of our Class B common stock, and no shares of our Class C common Stock outstanding as of January 31, 2018, and reflected: • (i) 387,934 shares of preferred stock and 3,914,934 shares of Class B common stock that will convert into Class A common stock immediately prior to the completion of this offering pursuant to the terms of certain transfer agreements, and (ii) 220,965,979 shares of preferred stock that will automatically convert into shares of Class B common stock immediately prior to the completion of this offering pursuant to the terms of our amended and restated certificate of incorporation; • 24,014,229 shares of our Class B common stock subject to RSUs, for which the service condition was satisfied as of January 31, 2018, and for which we expect the Performance Vesting Condition to be satisfied upon the effectiveness of our registration statement related to this offering (after repurchasing 15,353,360 shares of our Class B common stock subject to RSUs to satisfy tax withholding obligations at an assumed tax rate of 39%); and • 22,100,000 shares of our Class A common stock subject to RSAs that were granted pursuant to our Co­Founder Grants, and vest upon the satisfaction of the service condition and achievement of certain stock price goals. We have based our calculation of the percentage of beneficial ownership after this offering on shares of our Class A common stock issued by us in our initial public offering and shares of Class A common stock outstanding immediately after the completion of this offering, assuming that the underwriters will not exercise their option to purchase up to an additional shares of our Class A common stock from us and the selling stockholders in full. We have deemed shares of our common stock subject to stock options that are currently exercisable or exercisable within 60 days of January 31, 2018, or issuable pursuant to RSUs which are subject to vesting and settlement conditions expected to occur within 60 days of January 31, 2018, to be outstanding and to be beneficially owned by the person holding the stock option or RSU for the purpose of computing the percentage ownership of that person. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. 154 https://www.sec.gov/Archives/edgar/data/1467623/000119312518055809/d451946ds1.htm 162/235
