Exicure, Inc. Received Nasdaq Delinquency Notice on Late Filing of its Form 10-K

Exicure, Inc. ("Exicure" or the "Company") (Nasdaq: XCUR), announced today it received a notice of non-compliance from Nasdaq Stock Market LLC ("Nasdaq") on April 17, 2024 notifying the Company that, as a result of the Company's failure to timely file its Annual Report on Form 10-K for the year ended December 31, 2023 (the "Form 10-K"), the Company is not in compliance with Nasdaq Listing Rule 5250(c)(1) (the "Rule"), which requires listed companies to timely file all periodic financial reports with the U.S. Securities and Exchange Commission (the "SEC").

The Letter states that the Company must submit an update to its original plan to regain compliance with respect to the filing requirements. The plan initially related to the Company's delinquency in filing its Form 10-Q for the quarter ended September 30, 2023, and the Nasdaq staff granted an exception giving the Company until May 20, 2024 to file the third quarter Form 10-Q. Any additional exceptions to allow the Company to regain compliance with all delinquent filings (both the third quarter Form 10-Q and the Form 10-K) will be limited to May 20, 2024.

The Company is working diligently to complete its Form 10-K and intends to file the Form 10-K as soon as practicable to regain compliance with the Rule.
