. III. Main content of investor relations activities

Question 1: What are the driving factors for the company's performance growth in the third quarter? Answer: In the first three quarters of 2025, the company achieved a revenue of 586 million yuan, a year-on-year increase of 41.35%; The net profit attributable to shareholders of the listed company was 150 million yuan, a year-on-year increase of 91.95%; After deducting non recurring gains and losses, the net profit was 147 million yuan, a year-on-year increase of 85.23%. The performance growth is mainly due to the continuous increase in the proportion of sales revenue from insulation molded parts, as well as the optimization of sales structure brought about by the increase in direct sales proportion, forming a benign development pattern of both quantity and price rising and structural optimization. Question 2: What is the current capacity utilization situation? What is the capacity construction and release plan for the second phase project? Answer: Currently, the overall capacity utilization rate of the company is close to saturation, and the production of insulation molded parts can be further increased by adding equipment and optimizing scheduling. The new production line of the second phase project of Guangxin New Material Technology (Changsha) Co., Ltd., a wholly-owned subsidiary of the company, is currently in the trial production and process integration stage. The capacity ramp up will be promoted in stages. It is expected that after the final acceptance of the project, the capacity will be gradually and fully released until it reaches full capacity. Question 3: Does the company strategically tilt towards high value-added insulation molded parts?

Answer: Starting from 2022, the company has made "insulation molded parts" a strategic core product, continuously increasing resource investment and continuously increasing the proportion of molded parts revenue. In the future, the company will prioritize the allocation of insulation fiber material resources towards insulation fiber molded parts based on order structure and production capacity deployment pace. The company will continue to promote product structure optimization and consolidate its dominant position in core business. Question 4: What is the company's overseas market expansion situation? Answer: Currently, the company's overseas business is piloted in regions such as Russia, Brazil, and Kazakhstan, with a focus on promoting insulation fiber board products. After the second phase of production capacity of Guangxin New Material Technology (Changsha) Co., Ltd., a wholly-owned subsidiary of the company, is gradually released, the company plans to further expand into other overseas markets and steadily promote its international layout. Question 5: What is the latest investment structure and business plan of the Changzhou subsidiary? Answer: The registered capital of the company's controlling subsidiary, Jiangsu Xinrun Electric New Materials Co., Ltd., is 10 million yuan, and the company holds a 60% stake. The holding subsidiary is positioned as the "East China Insulation Forming Parts Manufacturing and Service Center", aiming to strengthen its localized service capabilities for customers in the transformer industry cluster and improve the supply response efficiency of insulation forming parts products. In the future, the company will rely on this subsidiary to further deepen market expansion and customer service in Jiangsu and surrounding areas, and promote the sustained growth of regional business.
