 stockholders” from engaging in a “business
combination” with a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder
was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of
interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested
stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by our Board of Directors.

Preferred stock

Our Board of Directors will have the authority,
without further action by our stockholders, to issue up to shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by our Board of Directors. The existence
of authorized but unissued shares of preferred stock would enable our Board of Directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest, or other means.

Stockholder meetings

Post-IPO Bylaws will provide that, once our Class B common stock no longer represents a majority of voting power of our outstanding capital stock, a special meeting of stockholders may be called only by
our chairman of the Board of Directors, chief executive officer or president (in the absence of a chief executive officer), or by a resolution adopted by a majority of our Board of Directors.

Requirements for advance notice of stockholder nominations and proposals

Our Post-IPO Bylaws will establish advance notice procedures with respect to stockholders seeking to bring business before our
annual meeting of stockholders, or to nominate candidates for election as directors, other than nominations made by or at the direction of the Board of Directors, or a committee thereof. Our Post-IPO Bylaws
will also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for
directors at our meetings of stockholders.

Stockholder action

Our Post-IPO Certificate of Incorporation and Post-IPO Bylaws will provide that, once our
Class B common stock no longer represents a
