EXPLANATORY NOTE

On April 2, 2019, X4 Pharmaceuticals, Inc. (the “Company”) filed a Current Report on Form 8-K (the “Original Form 8-K”) under Item 5.02 to report the election of Murray W. Stewart, M.D. to the Company’s Board of Directors (the “Board”) effective as of March 29, 2019. Because Dr. Stewart was not immediately appointed to serve on any Board committee, disclosure of the Board committees on which he would serve was not included in the Original Form 8-K in accordance with Instruction No. 2 to Item 5.02 of Form 8-K. This Current Report on Form 8-K/A reports Dr. Stewart’s Board committee assignments. No other changes have been made to the Original Form 8-K.

Item 5.02

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

Dr. Stewart was appointed to serve as a member of the Company’s Audit Committee and Compensation Committee effective as of the Company’s 2019 annual meeting of stockholders, which is expected to be held on June 17, 2019.
