On August 21, 2026, Hang Seng Indexes Company unveiled the results of its quarterly index review as of June 30, 2026, revealing that SIGENERGY (06656) will be added to the Hang Seng Composite Index. The adjustment is scheduled to take effect after the market close on Friday, September 4, and will become active from Monday, September 7. In response, the Shanghai and Shenzhen stock exchanges are expected to update the list of eligible securities under the Stock Connect program accordingly.

SIGENERGY appears well-positioned for inclusion in the Stock Connect scheme, as it meets a range of criteria, including market capitalization and liquidity thresholds. The company previously announced that it expects first-half revenue to reach between RMB 9.5 billion and RMB 10 billion, representing a year-on-year surge of approximately 240% to 270%. Net profit is projected to land in the range of RMB 2.35 billion to RMB 2.45 billion, marking a rise of around 190% to 210% compared to the prior year. Profit attributable to shareholders of the company is also forecast to be between RMB 2.35 billion and RMB 2.45 billion, reflecting the same growth trajectory of 190% to 210%.

According to the company's announcement, the robust performance is primarily driven by the continued expansion of its core market scale and an increase in market share, which have collectively boosted sales volumes.
