Explanatory Note:
This joint statement on Schedule 13D/A (this “Statement”) is filed with respect to the common stock, par value $0.01 per share (“Common
Stock”), of Aptinyx Inc., a Delaware corporation (the “Issuer”).
This Amendment No. 2 (this “Amendment”) amends and
supplements the Schedule 13D originally filed with the Commission on July 2, 2018, as amended by Amendment No. 1 filed with the Commission on February 12, 2020 (collectively, the “Original Schedule 13D”). This Amendment is
being filed to update the aggregate percentage of the Issuer’s Common Stock owned by the Reporting Persons due to dilution caused by the Issuer’s sales of additional shares of its Common Stock from time to time since the date of the filing
of the Original Schedule 13D and not in connection with a disposition of any shares by the Reporting Persons. Such dilution resulted in a decrease of over one percent (1%) in the aggregate percentage ownership reported by the Reporting Persons in
the Original Schedule 13D. Only those items that are hereby reported are amended; all other items reported in the Original Schedule 13D remain unchanged. Capitalized terms contained herein but not otherwise defined shall have the meanings ascribed
to such terms in the Original Schedule 13D. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.
SIGNATURE
After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
Dated: February 14, 2023.
