新股前瞻|铜博科技：高性能铜箔第二大玩家，募资扩产能否破解低毛利率瓶颈？

Core Viewpoint - The demand for electrolytic copper foil is rapidly increasing due to the rising penetration of electric vehicles, the expansion of the energy storage industry, and the rapid iteration of 5G/6G communication technologies. The technology barriers and supply stability of high-performance electrolytic copper foil have become the focal points of the industry chain [1][15]. Company Overview - Tongbo Technology, established in 2016, is a leading provider of electrolytic copper foil solutions in China, focusing on the design, research and development, production, and sales of high-performance electrolytic copper foil. By 2024, it is projected to be the second-largest producer of high-performance lithium battery copper foil in China, with a market share of 13% [2][19]. Product Portfolio - The company's product range includes standard and high-performance lithium battery copper foil, essential for lithium-ion batteries in electric vehicles, energy storage systems, and consumer electronics. It also produces electronic circuit copper foil used in printed circuit boards (PCBs) and copper-clad laminates (CCLs), with applications in 5G/6G communication, AI servers, and automotive electronics [4][8]. Production Capacity and Supply Chain - Tongbo Technology has established a large-scale production layout with an integrated production base in Fuzhou, Jiangxi, featuring a factory with an annual capacity of 20,000 tons and another with 50,000 tons, achieving a total designed capacity of 70,000 tons. The capacity utilization rate reached 91.3% in the first nine months of 2025 [6][8]. - To meet market demand, the company is constructing an automated manufacturing plant in Sichuan with an initial design capacity of 20,000 tons, expected to commence large-scale production in Q4 2026 [8]. Financial Performance - The company has shown stable revenue growth, with revenues of 3.163 billion yuan in 2023, projected to increase to 3.212 billion yuan in 2024, and further grow by 24.4% to 2.849 billion yuan in the first nine months of 2025 [9][10]. - However, the company faces cash flow management pressures, with net cash outflows from operating activities of 715 million yuan in 2024 and 349 million yuan in the first nine months of 2025 [13][14]. Profitability and Market Trends - The company's gross margin has fluctuated due to industry cycles and product structure, with a gross margin of 6.7% in 2023, dropping to 3.1% in 2024, and recovering to 4.8% in the first nine months of 2025 as market demand improves [11][12]. - The global electrolytic copper foil market is expected to grow significantly, with a compound annual growth rate (CAGR) of 26.1% from 2020 to 2024, and China's market is projected to grow at a CAGR of 30.4% during the same period [15][18]. Industry Environment and Competitive Landscape - The national support for the new energy industry and the promotion of carbon neutrality goals provide a favorable development environment for the electrolytic copper foil industry. The company has obtained high-tech enterprise status, enjoying a 15% corporate income tax rate [18]. - The industry has a low concentration, with the top ten manufacturers holding only 48.1% of the market share, indicating significant room for consolidation. Tongbo Technology's technological research and development, customer resources, and production capacity position it well for market share expansion [18][19].
