MNKD MannKind Corporation

On March 1, 2017, MannKind Corporation (the “Company”) held a Special Meeting of Stockholders (the “Special Meeting”) at which the Company’s stockholders approved a proposal to amend the Company’s Amended and Restated Certificate of Incorporation to (i) effect a reverse stock split of the Company’s outstanding common stock at a ratio in the range of 1-for-3 to 1-for-10, with such ratio to be determined in the discretion of the Company’s board of directors and with such reverse stock split to be effected at such time and date, if at all, as determined by the Company’s board of directors in its sole discretion, and (ii) reduce the number of authorized shares of the Company’s common stock in a corresponding proportion to the reverse stock split, rounded to the nearest whole share (collectively, the “Reverse Split Proposal”).

On March 1, 2017, following stockholder approval of the Reverse Split Proposal, the Company’s board of directors approved a reverse stock split of the Company’s common stock at a ratio of 1-for-5. On March 1, 2017, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment of its Amended and Restated Certificate of Incorporation (the “Charter Amendment”) to (i) effect the 1-for-5 reverse stock split of the Company’s outstanding common stock and (ii) reduce the authorized number of shares of the Company’s common stock from 700,000,000 to 140,000,000 shares. The Charter Amendment will be effective at 5:01 p.m. Eastern Time on March 2, 2017 (the “Effective Time”).

The Charter Amendment provides that, at the Effective Time, (a) every five shares of the Company’s issued and outstanding common stock will automatically be combined into one issued and outstanding share of common stock, without any change in par value per share, and (b) the number of authorized shares of common stock will be reduced to 140,000,000 shares. As a result of the reverse stock split, proportionate adjustments will be made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock units and warrants issued by the Company and outstanding immediately prior to the Effective Time, which will result in a proportionate decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock units and warrants, and, in the case of stock options and warrants, a proportionate increase in the exercise price of all such stock options and warrants. In addition, the number of shares authorized for future grant under the Company’s equity incentive/compensation plans immediately prior to the Effective Time will be reduced proportionately.

The Company’s common stock will begin trading on The NASDAQ Global Market on a split-adjusted basis when the market opens on March 3, 2017. The new CUSIP number for the Company’s common stock following the reverse stock split is 56400P 706.

The foregoing summary of the Charter Amendment is qualified in its entirety by reference to the Charter Amendment, which is attached to this Current Report on Form 8-K as Exhibit 3.1 and is incorporated herein by reference.
