November 15, 2021 at 17:48 PM EST

Exicure, Inc.® (NASDAQ: XCUR) today announced that it has filed a Form 12b-25 with the U.S. Securities and Exchange Commission (the “SEC”) in connection with its Quarterly Report on Form 10-Q for the period ended September 30, 2021 (the “Form 10-Q”).

Exicure, Inc. (the “Company”) is unable to file its Quarterly Report on Form 10-Q for the quarter ended September 30, 2021 (the “Q3 2021 10-Q”) with the SEC within the prescribed time period without unreasonable effort or expense. On November 9, 2021, the Audit Committee of the Board of Directors of the Company was notified of a claim made by a former Company senior researcher regarding alleged improprieties that researcher claims to have committed with respect to the Company’s XCUR-FXN preclinical program for the treatment of Friedreich’s ataxia. The Audit Committee has retained external counsel to conduct an internal investigation of the claim. The Company is currently unable to predict the timing or outcome of the investigation. Despite working diligently in an effort to timely file its Q3 2021 10-Q, the Company requires additional time to complete certain disclosures and procedures, including disclosures relating to the internal investigation.

The Company expects to file its Q3 2021 10-Q with the SEC as soon as practicable, and no later than the fifth calendar day following the prescribed due date, in accordance with Rule 12b-25.
