On June 1, Tianyu Advanced fell 3.04% in regular trading, trading at HK$102.2/share, with trading volume of HK$188 million.

On the news front, the broader semiconductor sector continued to weaken, with the National Integrated Circuit Industry Investment Fund progressively reducing its holdings in multiple core semiconductor names including SICC and Debond Technology, triggering sector-wide selling pressure. Tianyu Advanced was dragged down by this sector-level retreat.

Additionally, the company recently disclosed that shareholders holding over 5% of shares, together with their concert parties, reduced their combined stake from 8.00% to 6.83%, crossing the 1% threshold for disclosure. This followed four block trades on May 27 executed at a 10% discount totaling over RMB 81 million, and six additional block trades on May 28. Combined with concentrated profit-taking following the stock's sharp rally earlier in the week — when shares surged over 16% on May 27 driven by AI power supply demand narratives for silicon carbide — market sentiment turned cautious, extending the pullback.
