On September 18, SIGENERGY rose 5.44% in regular trading, trading at HKD 325.6/share, with turnover reaching HKD 126 million. The rebound followed a period of pressure after the stock declined over 6% on September 16 amid concerns over margin compression and industry profitability headwinds.

On the news front, China's new power system buildout is accelerating, with the two major grid operators investing a combined nearly RMB 400 billion in the first half, driving sustained energy storage installation demand. More critically, leading inverter companies are set to implement price increases of 5% to 15% starting September 20, fueling market expectations that the energy storage supply chain may be re-entering a volume-price upcycle. The improved sentiment lifted the broader storage sector.

Previously, SIGENERGY's stock had come under selling pressure after its interim results revealed gross margin narrowing sharply to 40.5% from 51.9% a year earlier, attributed to rising raw material costs and intensified channel incentives — despite reporting revenue of RMB 9.87 billion, up 261.2% year-over-year, and adjusted net profit of RMB 2.49 billion, up 135.8%.
