Erroneous Filing of Prospectus Supplement

K Wave Media Ltd. (the “Company”) hereby informs shareholders and the investing public that on August 3, 2026, a prospectus supplement (the “Prospectus Supplement”) was filed with the U.S. Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b)(5) under the Securities Act of 1933, as amended, relating to an at-the-market offering of up to $5,058,329 of the Company’s ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), pursuant the Company’s registration statement on Form F-3 (File No. 333-297167).

The Company hereby announces that the Prospectus Supplement was filed in error, and no Equity Distribution Agreement has been entered into by the Company and D. Boral Capital LLC at this time. The at-the-market offering described in the Prospectus Supplement is not proceeding, and no sales of Ordinary Shares have been or will be made pursuant to the Prospectus Supplement or the Sales Agreement. The Prospectus Supplement should be disregarded in its entirety, and investors should not rely on the information contained therein for any purpose.

The Company intends to file a supplement to the Prospectus Supplement to formally terminate the offering described therein. Until such time as the Company files a further prospectus supplement or makes a further public announcement regarding any at-the-market offering, no offering of Ordinary Shares under the Prospectus Supplement is authorized or being conducted.
