Item 5.08. Shareholder Director Nominations.

To the extent applicable, the information in Item 8.01 of this Current Report on Form 8-K is incorporated by reference into this Item 5.08.

Item 8.01. Other Events.

On July 16, 2026, the Board of Directors (the "Board") of Polaryx Therapeutics, Inc. (the "Company") determined that the Company's 2026 Annual Meeting of Stockholders (the "Annual Meeting") will be held virtually on September 10, 2026. The Company will provide additional details regarding the time and matters to be voted on at the Annual Meeting in the Company's proxy statement for the Annual Meeting to be filed with the U.S. Securities and Exchange Commission (the "SEC") prior to the Annual Meeting. Stockholders of record of the Company's common stock at the close of business on July 27, 2026 will be entitled to notice of, and to vote at, the Annual Meeting and any adjournments or postponements thereof. The Company, however, reserves the right to change the record date, meeting date, and meeting location prior to the Annual Meeting.

Because the Company did not hold an annual meeting of stockholders during 2025, stockholders of the Company who wish to have a proposal considered for inclusion in the Company's proxy materials for the Annual Meeting pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended, (the "Exchange Act") must ensure that such proposal is delivered to or mailed to and received by the Company to the attention of Alex Yang at South Tower,140 E Ridgewood Avenue, Suite 415, Paramus, NJ 07652 on or before the close of business on July 27, 2026, which date the Company has determined is a reasonable time before it expects to begin to print and distribute its proxy materials.

In addition to complying with the July 27, 2026 deadline, stockholder director nominations and stockholder proposals intended to be considered for inclusion in the Company's proxy materials for the Annual Meeting must also comply with all applicable SEC rules, including Rule 14a-8 under the Exchange Act, Nevada corporate law and the Company's Amended and Restated Bylaws. Any director nominations and stockholder proposals received after July 27, 2026 will be considered untimely and will not be considered for inclusion in the proxy materials for the Annual Meeting nor will it be considered at the Annual Meeting.
