MNKD 2018 Proxy Statement

• You may attend the Annual Meeting and vote in person. Simply attending the Annual Meeting will not, by itself, revoke your proxy. Your most current proxy, whether submitted by proxy card, telephone or internet, is the one that is counted. If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank. How are votes counted? Votes will be counted by the inspector of election appointed for the meeting, who will separately count, with respect to the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and with respect to other proposals, “For” and “Against” votes, abstentions and, if applicable, broker non-votes. Abstentions will be counted towards the vote total for each proposal, except with respect to the election of directors, and will have the same effect as “Against” votes. Broker non-votes will have no effect and will not be counted towards the vote total for any proposal. What are “broker non-votes”? Broker non-votes occur when a beneficial owner of shares held in street name does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed “non-routine.” Generally, if shares are held in street name (shares are held by your broker as your nominee), the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If you do not give instructions to your broker, your broker can vote your shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are generally those involving a matter that may substantially affect the rights or privileges of stockholders, such as mergers or stockholder proposals, election of directors (even if not contested) and executive compensation, including the stockholder advisory votes on executive compensation. Proposals 1, 2, 3 and 4 regarding the election of directors, the approval of the 2018 Plan, the amendment of the ESPP, and the advisory vote regarding executive compensation, respectively, are non-routine matters. Proposal 5 to ratify Deloitte & Touche LLP as our independent registered public accounting firm is a routine matter. How many votes are needed to approve each proposal? For the election of directors, the seven nominees receiving the most “For” votes (among votes properly cast in person or by proxy) will be elected. Only votes “For” or “Withhold” will affect the outcome. Only the seven nominees named herein have been properly nominated for election as directors. Proposals 2 3, 4 and 5 regarding, respectively, adoption of the 2018 Plan, approval of an amendment to the ESPP, approval on an advisory basis of the compensation of the Company’s named executive officers and ratification of the Audit Committee’s selection of the independent registered public accounting firm, must receive a “For” vote from the majority of shares present and entitled to vote either in person or by proxy in order to be approved. If you “Abstain” from voting on any of these proposals, it will have the same effect as an “Against” vote. Broker non-votes will have no effect. What is the quorum requirement? A quorum of stockholders is necessary to hold a valid Annual Meeting. A quorum will be present if at least a majority of the outstanding shares entitled to vote are represented by stockholders present at the Annual Meeting or by proxy. On the record date, there were 123,011,353 shares outstanding and entitled to vote. Thus, 61,505,677 shares must be represented by stockholders present at the Annual Meeting or by proxy to have a quorum. 5
