Semilux International Ltd. shares surged 51.5% to $0.4302 in Nasdaq midday trading Wednesday. Volume crossed 167 million shares, with the stock trading between $0.297 and $0.6486. That put the Taiwan optical and LiDAR firm’s market cap at roughly $17.4 million.
Semilux is moving more like a small Nasdaq company under threat of delisting than a normal tech stock. The stock’s surge is attracting short-term traders, but that spike alone isn’t solving the ongoing compliance problems with the shares.
Semilux on May 22 said in a filing that Nasdaq plans to delist its shares from the Nasdaq Capital Market unless it asks for a hearing in time. Nasdaq flagged that Semilux didn’t get its stock price back above the $1 minimum needed for compliance by May 11. It also pointed to the company missing its 2025 Form 20-F annual report, which foreign private issuers have to file.
Semilux, in the filing signed by CEO Yung-Peng Chang, said it is “actively working to address” its bid-price, stockholders’ equity and filing problems. The company also said there’s “no assurance” the Nasdaq panel will allow it to stay listed or that Semilux can meet requirements during any exception period.
There’s another deadline looming. In January, Semilux said Nasdaq notified it that the company’s market value of listed securities was under the $35 million minimum. Semilux has until June 29, 2026, to fix it. Nasdaq rules say the company needs its MVLS at $35 million or above for at least 10 business days in a row to comply.
The stock’s run came while the rest of the market dropped. The Invesco QQQ Trust slipped 0.5%, tracking big tech names, and the iShares Russell 2000 ETF lost 1.6%. Ouster fell 7.0% and Hesai Group was down 2.6% among LiDAR and optical-sensing names. Semilux still moved higher, so the gain looked tied to the stock rather than the whole sector.
Semilux operates via Taiwan Color Optics, which says it makes AI-powered optical and LiDAR products for markets like industry, defense and mobility. LiDAR uses lasers to measure distance and shape. The company says it also offers integration for UAVs, or drones.
The stock got a defense-drone and sensing story, but on Wednesday, trading was still about price and compliance. The market moved up a name still under Nasdaq’s $1 minimum bid, with shares also well under the 52-week high of $1.48.
Risks are clear. The rally could reverse fast if Nasdaq’s hearing goes against the company, the annual report keeps lagging, or traders see the surge as just a volume blip in a quiet stock. Nasdaq rules let the hearings panel grant an exception or stick with delisting, and the stay for late filings doesn’t last forever.
Semilux has the market’s eye for now, but still lacks compliance. Without that, traders are more likely to focus on each filing, hearing update, or if the stock closes near $1, than on any operating news.
