Huahai convertible bonds trigger first optional put-back

Zhejiang Huahai Pharmaceutical Co. (SSE:600521) announced the first optional put-back of its "Huahai convertible bonds," triggered after the company's stock price consistently traded below 70% of its current conversion price for 30 consecutive trading days. The put-back price is set at 100.30 yuan per bond, which includes accrued interest and tax. Investors can exercise this option from December 22, 2025, to December 26, 2025.

During the put-back period, "Huahai convertible bonds" will continue to trade but will cease to be convertible into shares. The put-back funds are scheduled for distribution on December 31, 2025. Bondholders have the option to sell all or part of their unconverted bonds back to the company; this is not a mandatory put-back.

Investors are advised that the current market price of the convertible bonds may be higher than the put-back price, and choosing to exercise the put-back option could result in a loss. The put-back interest is calculated at 2.00% annual interest over 54 days, amounting to approximately 0.30 yuan per bond.
