Semilux Receives Notification of Deficiency from Nasdaq Related to Delayed Filing of Annual Report on Form 20-F

Taipei, Taiwan, June 02, 2025 (GLOBE NEWSWIRE) -- Semilux International Ltd. (NASDAQ:SELX) (“SELX” or the “Company”) announced that it received a delinquency notification letter on May 27, 2025 (the “Deficiency Letter”) from the Listing Qualifications Department of The Nasdaq Stock Market Inc. (the “Nasdaq”) notifying the Company that it is no longer in compliance with the Nasdaq Listing Rule 5250(c)(1) (the “Listing Rule”) for continued listing due to its failure to timely file its annual report on Form 20-F for the year ended December 31, 2024 (the “Annual Report”) with the U.S. Securities and Exchange Commission. The Listing Rule requires Nasdaq-listed companies to timely file all required periodic reports with the SEC.

In accordance with Nasdaq’s listing rules, the Company has 60 calendar days after the Deficiency Letter to submit a plan to regain compliance with the Listing Rule. Following receipt of such plan, Nasdaq may, at its discretion, grant an extension of up to 180 calendar days from the Annual Report’s due date, or until November 11, 2025, for the Company to regain compliance. The Company was not able to file the Annual Report by the prescribed deadline as extended pursuant to Rule 12b-25(b)(2)(ii) under the Securities Exchange Act of 1934 primarily due to additional time being required to finalize its financial statements and complete the preparation of the Annual Report for the fiscal year ended December 31, 2024. The Company continues to work diligently to complete the Annual Report and intends to file it with the SEC as soon as reasonably practicable. The Deficiency Letter has no immediate impact on the listing of the Company's ordinary shares on the Nasdaq Capital Market.

This announcement is made in compliance with the Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a notification of deficiency. About Semilux International Ltd.
