For specific related information, please refer to periodic reports. An investor asked on the investor interaction platform: Hello, Board Secretary. Recently, LME copper prices have risen sharply. Under the company’s strictly implemented hedging strategy, did this generate positive gains from closing positions during the reporting period, or was there a slight loss? Approximately how much was the amount? In addition, as the company’s revenue scale expanded, how well did net operating cash flow match net profit in 2025? Was there any cash flow strain caused by prepayments for raw material procurement? On March 19, Jintian Co., Ltd. stated on the investor interaction platform that the company’s copper processing products adopted a pricing model of “raw material prices + processing fee” and carried out hedging operations in strict accordance with the Hedging Management System to reduce the impact of raw material price fluctuations on the company’s net profit. At present, fluctuations in copper prices had a relatively small impact on the company’s operating performance. For specific related information, please refer to periodic reports. On March 18, when responding to investor questions on the interaction platform, Jintian Co., Ltd. stated that the company had continued to expand its technological leadership in high-voltage electromagnetic flat wire and had further advanced cooperation on new energy high-voltage electromagnetic flat wire projects with world-class OEMs and motor suppliers.

In addition, the company had a solid client base and sound technical reserves in the chip and semiconductor sector. The company will closely monitor and follow market demand in the chip and semiconductor sector, further improve its product portfolio, and enhance its competitive edge. For specific information, please refer to the periodic reports. On March 17, Jintian Co., Ltd. said in response to investor questions on an interactive platform that the company remained committed to advancing its internationalization strategy, and construction of its newly built Thailand production site was progressing smoothly. The company's copper semis products exported outside China had an overall relatively high gross margin. In H1 2025, revenue from its principal operations outside China was up 21.86% YoY and continued to maintain a solid growth trend. The steady growth of business outside China laid a solid foundation for the company to deepen the upgrading of its global product and client mix. For specific information, please refer to the periodic reports. Jintian Co., Ltd.'s 2025 earnings forecast showed that, based on preliminary estimates by its finance department, the company expected net profit attributable to owners of the parent for 2025 to reach 700 million to 800 million yuan, representing an increase of 237.9574 million to 337.9574 million yuan from the same period last year (statutorily disclosed data), up 51.50% to 73.14% YoY. Net profit attributable to owners of the parent excluding non-recurring gains and losses for 2025 was expected to reach 440 million to 528 million yuan, representing an increase of 101.4004 million to 189.4004 million yuan from the same period last year (statutorily disclosed data), up 29.95% to 55.94% YoY. Regarding the main reasons for the expected increase in results for the period, Jintian Co., Ltd. stated: In 2025, the company implemented its "dual upgrade of products and clients" strategy, with product applications in high-end fields continuing to deepen; it stepped up expansion among clients outside China, and sales in markets outside China continued to grow; meanwhile, through digitalization initiatives, it improved operating and management efficiency, and its product gross margin level and profitability improved YoY. On January 23, Jintian Co., Ltd. said in response to investor questions on an interactive platform that Phase I of its Baotou base had been put into operation, and the annual capacity of rare earth permanent magnets had been increased to 9,000 mt. The company is currently actively advancing Phase II of the Baotou base project, with the aim of further increasing capacity to 13,000 mt. The company has a solid client base and technical reserves in the robotics field, and some rare earth permanent magnets have already been applied in the robotics sector. The company will closely monitor and follow market demand in the robotics field, further improve its product portfolio, and enhance its product competitiveness. A performance preview commentary on Jintian Co., Ltd. for 2025 released by Aijian Securities showed that the share repurchase demonstrated confidence in long-term development, while capital structure optimization was advancing steadily. The company’s high-end copper-based materials were being introduced at an accelerated pace to clients outside China in the computing power cooling sector, with sales rising rapidly and profitability improving significantly. 1) In terms of profitability, processing fees for copper busbar used in computing power are relatively high, and product mix upgrades are expected to continue lifting the company’s gross margin level; 2) In terms of shipment progress, in H1 2025, sales of the company’s copper busbar products in the cooling sector increased 72% YoY, and its high-precision profiled oxygen-free copper busbar has entered GPU cooling solutions of multiple global first-tier cooling module enterprises. The company’s copper heat pipes, liquid-cooling copper pipe & tube, and other products have also achieved bulk supply in computing servers of multiple top-tier enterprises. Copper prices fluctuations had a limited impact on the company’s profitability. 1) The company adopts a “copper prices + processing fee” pricing model, with revenue and profit primarily derived from processing fees rather than copper prices themselves. Processing fees are negotiated between the company and clients based on factors such as product specifications and process complexity, and show a certain degree of historical stickiness; 2) The company effectively hedges copper prices through hedging, while fluctuations in upstream raw material prices are mainly borne by downstream customers, resulting in a relatively small impact on the company’s profit; 3) Rapid copper prices fluctuations may affect downstream ordering willingness in phases and lengthen order cycles, but copper application scenarios are characterized by rigid demand, so the impact on total demand is limited, only changing the pace of copper product orders, and the company’s overall operating stability remains strong. The company is actively expanding into the “aluminum as an substitute for copper” direction, with material substitution optimizing the gross profit structure while enhancing its ability to hedge against copper prices fluctuations. 1) On a per-mt basis, the absolute value of processing fees for aluminum products is usually lower than that of copper-based solutions (at the same performance level, processing fees for high-precision aluminum extrusion are about 10,000 yuan/mt, versus about 20,000 yuan/mt for copper semis); however, since the per-mt price of aluminum semis is significantly lower than that of copper, usually about one-fourth of the latter, the material cost base is lower, increasing the share of processing fees in total product value. The corresponding processing fee rate of aluminum-based solutions is about 13–14 pct higher than that of copper-based solutions, providing positive support to the company’s overall gross margin; 2) In terms of supply progress, the company’s electromagnetic flat aluminum wire and aluminum 3D bent busbars for vehicles have entered the certification and mass supply stage, while inner-grooved aluminum pipe & tube for air conditioners has already begun small-batch supply. Risk Warning: Risks of lower-than-expected downstream demand for new energy or capacity release, rising copper prices, and changes in trade policies outside China.
