Sieyuan's growth bets and earnings offset foreign-buy curb and US grid order

400m yuan supercapacitor expansion Sieyuan will inject at least 400 million yuan of its own money into its wholly-owned subsidiary to expand supercapacitor capacity. Management says these products are moving from trials to bulk orders in power grids and data centers, a new growth line beyond its core grid equipment.
New capital commitment signals a fresh growth driver for the company.
First-half profit up 13%, Q2 jumped First-half revenue rose 27% to 10.8 billion yuan and net profit rose 13.2% to 1.46 billion yuan. Second-quarter profit of 914 million yuan was 66% higher than the first quarter, showing the business sped up. No dividend was paid, keeping cash for growth.
Earnings are the core fundamental driver of the stock's value.
US order curbs foreign grid equipment Trump signed an executive order restricting US purchases and imports of foreign-made grid gear, including transformers and battery storage. Sieyuan shares fell with the power-equipment sector. Companies say direct US revenue is small and rules are not yet written, so the real hit is unclear but sentiment is hurt.
A new regulatory threat that pressured the stock and the whole sector.
