Fireside Electronics Announcement: It is expected that the net profit attributable to the shareholders of the listed company from January 1, 2025 to June 30, 2025 will be a loss of 80-100 million yuan, a decrease of 61.28% to 101.61% compared to the same period last year. The net loss in the same period last year was 28.6559 million yuan. The basic earnings per share is expected to be a loss of 0.0984 yuan/share to 0.1273 yuan/share. During the reporting period, the company was continuously affected by the structural adjustment of the industry it belongs to, with traditional equipment orders failing to meet expectations, and relatively few product deliveries in the first half of the year. The company's important research projects have not yet been completed and validated, only some new products have been gradually produced and delivered in small batches. In addition, the gross profit margin has decreased due to the impact of product structure, leading to a decrease in both revenue and profit compared to the same period last year.
