Explanation of Responses:

( 1 )Includes 1,600 restricted stock units ("RSU"). Each RSU granted by Exicure, Inc. (the "Issuer") to Joshua Miller in connection with his employment with the Issuer represents a contingent right to receive one share of the Issuer's common stock upon vesting. One-fourth of the RSUs granted vested on May 15, 2023, and then one-sixteenth of the RSUs granted vest every three months thereafter for a total vesting period of four years. The RSUs are subject to forfeiture upon the occurrence of certain events until vested.

Remarks: General Explanatory Note: The Form 3 filed with the Securities and Exchange Commission (SEC Accession No. 0001698530-23-000045) on May 9, 2023 (the "Prior Filing") was inadvertently filed under the wrong Reporting Person's CIK, and thereafter corrected and re-submitted under the correct Reporting Person's CIK. The Prior Filing was submitted in error, is hereby withdrawn and therefore should be disregarded. Additionally, as a result of the error, the Prior Filing included incorrect information with respect to Joshua Miller. As reported in this amendment, Mr. Miller directly owns 1,600 RSUs and 533 shares of common stock granted by the Issuer. The original Form 3 also mistakenly indicated that Mr. Miller is a director, Chief Executive Officer and Chief Financial Officer and that the date of event requiring statement was April 26, 2023. As reflected in this amendment, Mr. Miller's correct title is Chief Accounting Officer and the correct date of event requirement statement is May 3, 2023.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
