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.

Four years ago, Central China Copper Co., Ltd., a subsidiary of China Copper Co., Ltd. (hereinafter referred to as "Central China Copper"), successfully developed 6e-06-meter rolled copper foil, setting a new record for the thinnest rolled copper foil in China. Four years later, at the electronica China in Munich, the company launched red-coated and black-coated foils with high flexibility and corrosion resistance, becoming one of the highlights of the exhibition. From thick copper strips to copper foils as thin as cicada wings, and from ordinary bare foils to high-end red-coated and black-coated foils, Central China Copper has carved out a unique path in product transformation and upgrading. From 2021 to 2024, the company's copper foil production and sales exceeded 2,000 mt for four consecutive years, and its copper foil business achieved profitability for five consecutive years. Applying "Lipstick" on "Cicada Wings" "Applying a uniform red coating on the surface of copper foil is like applying lipstick to a delicate cicada wing. Any slight misstep can result in color variations or peeling." Li Haifeng, a technician specializing in surface treatment, still vividly recalls the technical challenges faced during the initial trial production of red-coated foil. In early 2020, while maintaining stable production of qualified bare foil, Central China Copper set its sights on high-value-added treated foils and began attempting to produce red-coated foil. During the initial trial production, issues such as frequent red spots, color variations, and inadequate oxidation resistance during the electroplating process led to a scrap rate of over 50%. Watching dozens of tons of foil material turn into "colorful" scrap in the plating tanks, the technicians felt both heartache and helplessness. To overcome these challenges, the company's technical team members camped out by the production line day and night for several consecutive weeks. Their hard work paid off, as they finally identified the root cause of the problem: the instability of the electroplating solution formula and significant temperature fluctuations. They redesigned the electroplating solution formula, added new-type additives to control fluctuations in metal ion concentration, installed an online high-precision real-time temperature monitoring system to enable real-time regulation of the electroplating solution, and innovated the "layer-by-layer current method" process to achieve denser and more uniform crystallization of the red coating. In May 2020, Central China Copper shipped its first batch of 10 mt of red-coated foil to domestic customers, and the product quality received customer recognition. As one of the earliest companies in China to successfully develop red-coated foil, Central China Copper, after years of technological accumulation, now boasts product stability that far surpasses that of its peers. Its red-coated foil has become a sought-after product in the market, firmly occupying one-third of the market share and successfully entering the supply chain systems of top-tier enterprises in China's electronics industry. Finding Light in the Darkness of Black Foil With the consumer electronics industry moving towards lighter, thinner, and more flexible designs, the new energy sector entering a rapid development phase, and AI being widely applied across various industries, the market demand for black-coated foil has surged exponentially. Central China Copper Industry closely followed market changes and initiated R&D efforts for blackened foil in 2022. If the R&D of red-coated foil could be described as a "tough battle mode," then the R&D of blackened foil was a "peak performance mode," requiring not only uniform coverage of the blackened layer but also ensuring that it would not peel off or oxidize during subsequent processing. As the production technology for blackened foil had long been monopolized by Japanese companies, the R&D team of Central China Copper Industry had no process flows or technical parameters to refer to. At the beginning of trial production, the blackened foil produced frequently had issues such as color differences in the coating, oxidation spots on the shiny surface, and insufficient adhesion leading to powder shedding. "At that time, it was like being trapped in an endless darkness, with no light in sight," sighed Qiao Yafeng, the head of the R&D team. To break the deadlock as soon as possible, Central China Copper Industry collaborated with the University of Shanghai for Science and Technology and Chalco Academy on industry-university-research cooperation, with the latter providing experimental data support, while the R&D team of Central China Copper Industry was responsible for industrial transformation and verification. However, reality once again poured cold water on everyone. The blackened foil samples trial-produced in the laboratory had excellent indicators, but various issues arose after transferring to the production line. Qiao Yafeng led the team to re-examine over 100 sets of production process data and verify them one by one. After thousands of tests and continuous efforts over hundreds of days and nights, they finally saw the "dawn" of victory. In April 2023, Central China Copper Industry successfully trial-produced blackened foil on its production line, achieving a key leap from laboratory to mass production; in June 2023, the first batch of blackened foil officially passed domestic customer certification; in 2024, small-batch deliveries of blackened foil were made, with positive customer feedback. Capacity Expansion Opens Up New Growth Poles In May, the project construction of Central China Copper Industry entered a "golden period," with the company's new copper foil surface treatment unit project accelerating and scheduled for equipment installation in October and commissioning and production before the end of the year. As a key investment project for Central China Copper Industry in 2025, this project is of great significance for adjusting the product structure of copper foil and forming new profit growth points. Differentiated development of special copper foil products such as red-coated foil, blackened foil, and alloy foil to achieve import substitution of high-end products is the future development direction of Central China Copper Industry's copper foil products. Currently, constrained by the treatment line, the company's production capacity for high value-added treated foil is severely limited, making the addition of a new copper foil surface treatment unit imperative. The new copper foil surface treatment unit adopts domestically leading production processes and equipment, capable of producing high-quality, high-performance red-coated foil, blackened foil, and alloy foil. The intelligent design of this unit not only improves production efficiency but also ensures product stability and consistency. In addition, Central China Copper prioritizes environmental protection and sustainable development. The project has introduced a new zero-liquid-discharge wastewater system to achieve green production. The completion and commissioning of the new copper foil surface treatment unit will bring significant economic benefits to Central China Copper, with the annual capacity of high value-added copper foil expected to increase by over 40%. Qiao Yafeng stated, "The construction of the new copper foil surface treatment unit is an important step for Central China Copper to deepen its strategic layout in the copper foil product sector. We will take this as an opportunity to further optimize the product structure of copper foil, enhance our core market competitiveness, and position the company as a leading enterprise in the copper foil industry." "Leading development with 'strip' and securing the future with 'foil'." Moving forward, Central China Copper will continue to delve deeper into the copper foil sector, continuously improving product quality and service levels, and propelling the company towards the high-end of the copper processing industry chain. We will strive unremittingly to build a national high-end copper-based new material base and contribute to the construction of a "new Chalco" with exceptional material capabilities.
