Alteogen announced on the 16th through a regulatory filing that it has decided to provisionally put on hold the pursuit of transferring its listing to the securities market (KOSPI) at this time and to maintain its KOSDAQ market listing.

This decision follows the resolution passed at the extraordinary general meeting of shareholders on December 8, 2025, regarding the 'conditional delisting from the KOSDAQ market and pursuit of transfer listing to the securities market.' After comprehensively reviewing recent changes in the capital market environment and government and Korea Exchange policies aimed at revitalizing the KOSDAQ market, the company concluded that provisionally maintaining its KOSDAQ listing aligns with enhancing corporate value and maximizing shareholder interests.

However, this measure does not imply a complete withdrawal of the transfer listing plan. Alteogen plans to reconsider whether to proceed with the transfer listing and its timing in the future by comprehensively taking into account factors such as corporate value and the potential for enhancing shareholder interests. Once specific details are finalized, the company intends to make a disclosure in accordance with relevant laws and regulations.

The date of the decision is July 16, 2026. The relevant disclosures cited by the company include the resolution to convene a shareholders' meeting (extraordinary general meeting) on November 6, 2025, the decision to place the delisting approval on the agenda on November 6, 2025, and the outcome of the extraordinary general meeting held on December 8, 2025.
