Zuck cannot lose control of the company unless he chooses to. His interest is majority and fully controlling. The board is advisory at best, impotent otherwise.
The following are crucial snips from the S-1 filing:
Our CEO has control over key decision making as a result of his control of a majority of our voting stock.
As a result of voting agreements with certain stockholders, together with the shares he holds, Mark Zuckerberg, our founder, Chairman, and CEO, will be able to exercise voting rights with respect to an aggregate of xxx shares of common stock, representing a majority of the voting power of our outstanding capital stock following our initial public offering. As a result, Mr.ÂZuckerberg has the ability to control the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation, or sale of all or substantially all of our assets. In addition, Mr.ÂZuckerberg has the ability to control the management and affairs of our company as a result of his position as our CEO and his ability to control the election of our directors. Additionally, in the event that Mr. Zuckerberg controls our company at the time of his death, control may be transferred to a person or entity that he designates as his successor. As a board member and officer, Mr.ÂZuckerberg owes a fiduciary duty to our stockholders and must act in good faith in a manner he reasonably believes to be in the best interests of our stockholders. As a stockholder, even a controlling stockholder, Mr.ÂZuckerberg is entitled to vote his shares, and shares over which he has voting control as a result of voting agreements, in his own interests, which may not always be in the interests of our stockholders generally. For a description of these voting agreements, see "Description of Capital Stock-Voting Agreements."
Because Mr.ÂZuckerberg controls a majority of our outstanding voting power, we are a "controlled company" under the corporate governance rules for publicly-listed companies. Therefore, we are not required to have a majority of our board of directors be independent, nor are we required to have a compensation committee or an independent nominating function. In light of our status as a controlled company, our board of directors has determined not to have an independent nominating function and to have the full board of directors be directly responsible for nominating members of our board. Additionally, as described in the section entitled "Description of Capital Stock-Anti-Takeover Provisions-Restated Certificate of Incorporation and Bylaw Provisions," so long as the outstanding shares of our Class B common stock represent a majority of the combined voting power of our common stock, Mr.ÂZuckerberg will be able to effectively control all matters submitted to our stockholders for a vote, as well as the overall management and direction of our company.
