2/24/2018 S-1 Table of Contents SHARES ELIGIBLE FOR FUTURE SALE Prior to this offering, there has been no public market for our Class A common stock, and we cannot predict the effect, if any, that market sales of shares of our Class A common stock or the availability of shares of our Class A common stock for sale will have on the market price of our Class A common stock prevailing from time to time. Future sales of our common stock in the public market, or the availability of such shares for sale in the public market, could adversely affect market prices prevailing from time to time. As described below, only a limited number of shares of our Class A common stock will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Nevertheless, sales of our Class A common stock in the public market after such restrictions lapse, or the perception that those sales may occur, could adversely affect the prevailing market price at such time and our ability to raise equity capital in the future. Following the completion of this offering, based on the number of shares of our capital stock outstanding as of December 31, 2017, we will have a total of shares of our Class A common stock outstanding, shares of our Class B common stock outstanding, and no shares of Class C common stock outstanding. Of these outstanding shares, all shares of our Class A common stock sold in this offering will be freely tradable, except that any shares purchased in this offering by our affiliates, as that term is defined in Rule 144 under the Securities Act, would only be able to be sold in compliance with the Rule 144 limitations described below. The remaining outstanding shares of our common stock will be deemed “restricted securities” as defined in Rule 144 under the Securities Act. Restricted securities may be sold in the public market only if they are registered under the Securities Act or if they qualify for an exemption from registration under Rule 144 or Rule 701 under the Securities Act, which rules are summarized below. As a result of the lock­up and market standoff agreements described below and the provisions of our IRA described under the section titled “Description of Capital Stock—Registration Rights,” and subject to the provisions of Rule 144 or Rule 701, shares of our Class A common stock will be available for sale in the public market as follows: • beginning on the date of this prospectus, all shares of our Class A common stock sold in this offering will be immediately available for sale in the public market; and • beginning 181 days after the date of this prospectus (subject to the terms of the lock­up and market standoff agreements described below) additional shares will become eligible for sale in the public market, of which shares will be held by affiliates and subject to the volume and other restrictions of Rule 144, as described below. Lock­Up and Market Standoff Agreements Our executive officers, directors, and certain other holders of our capital stock and securities convertible into or exchangeable for our capital stock have agreed or will agree that, subject to certain exceptions, for a period of 180 days after the date of this prospectus, or lock­up period, we and they will not, without the prior written consent of Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC, dispose of or hedge any shares or any securities convertible into or exchangeable for shares of our capital stock; provided that if (i) at least 120 days have elapsed since the date of this prospectus, (ii) we have publicly released our earnings results for the quarterly period during which this offering occurred, and (iii) such lock­up period is scheduled to end during or within five trading days prior to a broadly applicable period during which trading in our securities would not be permitted under our insider trading policy, or a blackout period, such lock­up period will end ten trading days prior to the commencement of such blackout period. Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC may, in their discretion, release any of the securities subject to these lock­up agreements at any time.
