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

On March 10, 2019, Edward Mathers notified the Board of Directors (the “Board”) of Liquidia Technologies, Inc., a Delaware corporation (the “Company”), that he would not be standing for re-election as a director at the Company’s 2019 annual meeting of stockholders (the “2019 Annual Meeting”) and will resign as a Class I director and as a member of the Company’s Compensation Committee and Nominating and Corporate Governance Committee immediately prior to the conclusion of the 2019 Annual Meeting.  Mr. Mathers has served as (i) a director of the Company since July 2009, (ii) a member of the Company’s Compensation Committee since its formation in August 2016 and (iii) a member of the Company’s Nominating and Corporate Governance Committee since its formation in July 2018.  No disagreement with the Company caused, in whole or in part, Mr. Mathers’ refusal to stand for re-election.

Item 8.01                                           Other Events.

On March 10, 2019, the Board approved the reclassification of Dr. Stephen Bloch, the Chairman of the Board, from a Class II director to a Class I director such that, upon the effectiveness of Mr. Mathers’ resignation immediately prior to the conclusion of the 2019 Annual Meeting, no one class of directors will have more than one director more than any other class of directors. Dr. Bloch, along with Dr. Ralph Snyderman, an existing Class I director, have been nominated by the Board, on the recommendation of the Nominating and Corporate Governance Committee, for election at the 2019 Annual Meeting for a term of three years expiring at the Company’s 2022 annual meeting of stockholders.  Dr. Bloch will continue to serve as Chairman of the Compensation Committee and as a member of the Audit Committee.  Dr. Snyderman will continue to serve as Chairman of the Nominating and Corporate Governance Committee and Chairman of the Company’s Research and Development Committee.

Additionally, on March 10, 2019, the Board, on the recommendation of the Nominating and Corporate Governance Committee, appointed Arthur Kirsch to serve as a member of the Compensation Committee effective upon Mr. Mathers’ resignation immediately prior to the conclusion of the 2019 Annual Meeting.
