When asked, "What are the technological content and barriers of the company's rolled copper foil? Who are the domestic and international competitors? Which companies are downstream clients?" North Copper responded on the investor interaction platform on June 25: The technological content and barriers of the company's rolled copper foil are reflected in: 1. The long process flow of rolled copper foil, involving disciplines such as smelting, rolling, metal heat treatment, and electrochemistry, requires continuous trial production to accumulate a process database. This represents a long-term experiential barrier that cannot be quickly reverse-engineered. 2. Capital and hardware thresholds, with extremely high equipment investment, high barriers for equipment installation, commissioning, and operation, and severe limitations on product width and ultra-thin gauge. 3. Barriers in rolling and forming processes, which are also the highest thresholds—covering product thickness, sheet flatness, internal structure, and mechanical properties, as well as the synergistic barriers of dozens of interconnected processing steps. The consistency control across the entire process is far more demanding than the single-step electrodeposition process for copper cathode foil. Regarding the statement, "The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² copper clad laminate (CCL) project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation," North Copper responded on the investor interaction platform on June 25: The CCL construction portion of the company's 50,000 mt high-performance rolled copper foil and 2 million m² CCL project has not yet commenced due to insufficient relevant technology and talent reserves, out of prudence. Next, the company will decide on the CCL investment and construction plan based on thorough market surveys and scientific validation. North Copper responded on the investor interaction platform on June 25: The company seizes market opportunities, closely monitors downstream market demand, focuses on R&D for mid-to-high-end copper strip products and structural adjustments for rolled copper foil products, and is committed to filling gaps in its process lines and reaching its capacity standard, striving to turn losses into profits as soon as possible. Regarding the question, "When will the company's semi-annual report performance forecast announcement be released?", North Copper responded on the investor interaction platform on June 25: The company has scheduled the disclosure of its 2026 semi-annual report for August 27. If the conditions for a performance forecast are met, the company will release the announcement within the stipulated time. When asked, "After the implementation of the 'Regulations on the Implementation of the Mineral Resources Law of the People's Republic of China', has the related work on applying for the mining permit for the newly added copper ore at the Tongkuangyu Mine been accelerated? Could you discuss the company's near-term plans? If progress goes smoothly, based on the ore's copper grade and after deducting relevant costs, how much profit is this expected to bring to the company?" North Copper responded on the investor interaction platform on June 24: The detailed survey of deep-seated replacement resources at the Tongkuangyu Mine is a project to add reserves outside the current mining right's boundary at depth (elevation range: 80m to -325m), which is conducive to increasing the company's copper resource reserves and extending the mine's service life. Given that the replacement resources identified by the detailed survey have reached a large scale, according to reserve review and filing requirements, the exploration level must be achieved for resource reserve filing and for initiating the transition from exploration to mining. As the mine's production level shifts downward, the company will conduct further exploration work for deep-seated replacement resources at the next production level. The company currently has no relevant deep exploration plans. Regarding the question, "As a third-generation core substrate material for IC lead frames, could you briefly introduce the production and latest order status of your company's 5,000 mt chromium zirconium copper alloy product?", North Copper responded on the investor interaction platform on June 23: Our company has completed the casting ingot product for C18150 (chromium zirconium copper alloy); the subsequent copper strip process is currently under trial production.

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.

If these changes are implemented next year, they will significantly enhance the competitive advantages and shipment expectations of core enterprises within the existing supply chain system. Does your company have the competitive capability to enter the liquid cooling supply chain?" Jin Tian shares replied to investor inquiries on the interactive platform on November 24, Copper, with its excellent electrical and thermal conductivity, has become a core material for chip interconnection in advanced AI industries and heat dissipation in computing power facilities. The company has a solid client base and technical reserves in the chip computing power sector, with its high-precision special-shaped oxygen-free copper busbar products already applied in multiple top-tier GPU cooling solutions from several global leading cooling module enterprises. The company will closely monitor and follow market demands in the chip computing power sector, further improve its product lineup, and enhance product competitive advantages. The performance preview commentary for Jin Tian shares in 2025 released by Aijian Securities indicates: Share repurchases demonstrate long-term development confidence, and capital structure optimisation is progressing steadily. The company's high-end copper-based materials are accelerating their penetration into overseas clients in the computing power heat dissipation sector, with rapidly increasing sales and significantly improved profitability. 1) In terms of profitability, the processing fee rate for copper busbars used in computing power is relatively high, and product structure upgrades are expected to continuously elevate the company's gross profit level; 2) Regarding shipment progress, in H1 2025, the company's copper busbar sales in the heat dissipation sector increased by 72% YoY. High-precision special-shaped oxygen-free copper busbars have entered the GPU cooling solutions of several global leading cooling module enterprises, and the company's copper heat pipes, liquid-cooled copper pipes, and other products have also achieved bulk supply in the computing power servers of several top-tier enterprises. Copper price fluctuations have limited impact on the company's profits. 1) The company's product pricing follows a "copper price + processing fee" model, with core revenue and profits derived from processing fees rather than copper prices themselves. Processing fees are determined through negotiation between the company and clients based on factors such as product specifications and process complexity, with a certain historical stickiness; 2) The company achieves effective hedging against copper prices through futures, with the main impact of upstream raw material price fluctuations borne by downstream entities, having a relatively small effect on the company's profits; 3) Rapid fluctuations in copper prices may temporarily affect the willingness of downstream customers to place orders and extend the ordering cycle, but given the essential nature of copper applications, the total demand is minimally affected, only altering the pace of copper product orders. The company’s overall operational stability is strong. The company is actively positioning itself in the "aluminum as a substitute for copper" direction, optimizing its gross profit structure while enhancing its ability to hedge against copper price volatility. 1) On a per-ton basis, the absolute value of processing fees for aluminum products is typically lower than that for copper (under equivalent performance levels, high-precision aluminum extrusion processing fees are about 10,000 yuan/mt, while copper semis are around 20,000 yuan/mt); however, due to the significantly lower per-ton price of aluminum (usually about one-fourth that of copper), the base cost of materials is lower, increasing the proportion of processing fees in the total product value. The processing fee rate for aluminum solutions is approximately 13–14pct higher than that for copper, providing positive support for the company's overall gross margin; 2) Supply progress: The company's electromagnetic aluminum flat wire and 3D bent aluminum busbars for vehicles have entered the certification and mass production supply stage, and the inner-grooved aluminum pipe for air conditioners has begun small-scale supply. Risk warnings: There is a risk that new energy downstream demand or capacity release may fall short of expectations, along with risks of rising copper prices and changes in overseas trade policies.
