Item 8.01 Other Events

Early Redemption of Convertible Bonds

On November 10, 2025, Exicure, Inc. (the “Company”) redeemed in full the 4.5 billion KRW, approximately $3.125 million USD, aggregate principal amount of 2.90% Convertible Bonds due 2028 (the “Bonds”) previously issued by its wholly owned subsidiary, KC Creation Co., Ltd. (“KC Creation”), and held by the Company.

The Bonds were originally issued on April 30, 2025 as part of an internal capital structure strategy and are convertible into shares of KC Creation common stock under certain conditions. The early redemption was executed and funded through internal cash transfers. No third-party holders were involved in the transaction.

This redemption is part of the Company’s ongoing efforts to simplify its intercompany financing arrangements and

secure liquidity for the continued operations of the Company and development of its biotechnology business. The transaction will be eliminated in consolidation and is not expected to have a material impact on the Company’s consolidated financial statements.
