Semilux Announces Nasdaq Notification of Minimum Bid Price Deficiency

Posted on by

Taipei, Taiwan, Nov. 12, 2025 — Semilux International Ltd. (NASDAQ: SELX), referred to as “Semilux” or the “Company,” announced today that it has received a communication from The Nasdaq Stock Market LLC (“Nasdaq”). The letter informed the Company of its current non-compliance with Nasdaq Listing Rule 5550(a)(2), which stipulates a minimum bid price. This deficiency arises because the closing bid price of Semilux’s ordinary shares has fallen below $1.00 per share for 30 consecutive business days. In accordance with Nasdaq Listing Rule 5810(b), which mandates prompt disclosure of such deficiency notifications, this press release is being issued. It is important to note that this notification does not immediately impact the listing status of the Company’s ordinary shares, which will continue to be traded on Nasdaq under the ticker “SELX” without interruption.

Under Nasdaq Listing Rule 5810(c)(3)(A), Semilux is allotted a period of 180 calendar days, extending until May 11, 2026 (termed the “Compliance Period”), to rectify its non-compliance with Nasdaq’s minimum bid price criterion. Should the closing bid price of the Company’s ordinary shares reach at least $1.00 for a minimum of 10 consecutive business days at any point within this Compliance Period, Nasdaq will issue written confirmation of compliance, thereby closing the matter. If the Company fails to achieve the minimum bid price requirement within the Compliance Period, it may be eligible for an extension, provided there are no other outstanding deficiencies.

The Company plans to actively monitor the closing bid price of its ordinary shares. If deemed appropriate, Semilux will explore and potentially implement various available strategies, including but not limited to, executing a reverse stock split of its ordinary shares, to restore compliance with the Nasdaq Listing Rules’ minimum bid price requirement.
