We are registering the offer and sale from time to time of the Resale Shares covered by this
prospectus pursuant to the selling stockholder’s registration rights under a stockholders agreement between us and the selling stockholder. Subject to any contractual restrictions on it selling the shares of our Class A common stock that
it holds, the selling stockholder may offer, sell, or distribute all or a portion of its shares of our Class A common stock publicly or through private transactions at prevailing market prices or at negotiated prices. We will not receive any of
the proceeds from the sale of the Resale Shares owned by the selling stockholder. We will receive the proceeds from any exercise of the Options (as defined herein) for cash, which we intend to use for general corporate and working capital purposes.
See “Use of Proceeds” for additional information. Any proceeds from the exercise of the Options would increase our liquidity, but we are not currently budgeting for any cash proceeds from the exercise of Options when planning for
our operational funding needs. We will bear all costs, expenses, and fees in connection with the registration of these shares of our Class A common stock, including with regard to compliance with state securities or “blue sky” laws.
The selling stockholder will bear all commissions and discounts, if any, attributable to its sale of Resale Shares. See “Plan of Distribution” beginning on page 21 of this prospectus.
