On May 21, Biren Technology fell 3.12% in regular trading, trading at 48.66 HKD/share, with trading volume of approximately 48.03 million HKD. The decline comes as the stock continues to face pressure from its controlling shareholder and cornerstone investor lock-up period expiring on May 23.

The company announced on May 15 a proposed H-share stock option plan and share incentive plan, raising market concerns over potential equity dilution. Meanwhile, the controlling shareholder holds shares corresponding to a market value of approximately 32.64 billion HKD, with over ten cornerstone investors collectively holding shares worth approximately 5.38 billion HKD — all set to become tradeable on May 23. Despite a brief technical rebound on May 20 driven by a strategic cooperation agreement with Wanda Information, the dual overhang of dilution risk and imminent large-scale unlock continues to suppress investor sentiment as the expiry date draws closer.

Notably, the broader semiconductor sector showed strength today, with SMIC up 3.86% and Montage Technology up 6.54%, suggesting the decline is primarily stock-specific rather than sector-driven.
