The net profit attributable to the parent company's owners during the reporting period was in a loss, mainly due to the fact that the company, as the bidding entity, is still restricted by the blacklist of State Grid Corporation of China in 2025, and its bidding qualification with Southern Power Grid Company Limited will not be restored until early November 2025, resulting in a significant decline in operating income throughout the year; as a high-tech enterprise in the power industry that has always attached importance to research and development, in order to ensure future development, the company will continue to maintain a certain intensity of research and development investment in 2025; the company's fire protection business was greatly affected by the continuous adjustment in the real estate industry, leading to a significant decline in operating income.
