Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

As disclosed below under Item 5.07, Ms. Valerie L. Andrews resigned from the board of directors (the “Board”) of Juniper Pharmaceuticals, Inc. (the “Company”), effective July 7, 2015. The Company would like to thank Ms. Andrews for her service to the Board.

Item 5.07. Submission of Matters to a Vote of Security Holders.

At the 2015 Annual Meeting of Stockholders of the Company held on July 7, 2015, four proposals were submitted to the stockholders of the Company. The proposals are described in detail in the Company’s Definitive Proxy Statement on Schedule 14A filed with the U.S. Securities and Exchange Commission on June 4, 2015. The final results for the votes regarding each proposal are set forth below.

1. Stockholders voted on the election of seven directors to the Company’s Board to hold office for a one-year term until the annual meeting of stockholders in 2016 and until their successors are elected and qualified. The nominees to the Board received a majority approval of the votes cast and were re-elected, with the exception of Valerie Andrews and Donald Hunter, with the following results:

Ms. Andrews and Mr. Hunter received fewer votes for election than votes against. Ms. Andrews resigned from the Board, effective immediately; therefore, she no longer serves as a director of the Company.

Pursuant to our Amended and Restated Bylaws, Mr. Hunter tendered his resignation, subject to acceptance by the Board. The Nominating and Corporate Governance Committee of the Board will promptly consider Mr. Hunter’s resignation and recommend to the Board whether to accept the resignation or to take other action. The Board, excluding Mr. Hunter, will act on the recommendation of the Nominating and Corporate Governance Committee, and publicly disclose its decision no later than 90 days following the certification of the shareholder vote. The Nominating and Corporate Governance Committee, in making its recommendation, and the Board, in making its decision, will evaluate the resignation in light of the best interests of the Company and our stockholders and may consider any factors or information that it considers appropriate and relevant. In the interim, Mr. Hunter will continue to serve as a director and Chairman of the Audit Committee, and will not participate in the Board’s decision with respect to his tendered resignation.
