Summary of the Conference Call for Jing Sheng Mechanical & Electrical Co., Ltd. Company Overview - Jing Sheng Mechanical & Electrical Co., Ltd. specializes in the production of silicon carbide (SiC) substrates, with a focus on 8-12 inch core processes. The company has an annual production capacity of 300,000 pieces in Shangyu and is expanding to 600,000 pieces in Yinchuan, with plans to gradually transfer capacity to reduce costs. [2][3] Key Points and Arguments Industry and Market Dynamics - The SiC substrate market is primarily used in power applications (e.g., new energy vehicles, energy storage, data centers), optical applications, and advanced packaging. The market for power applications is estimated to be around 10 billion yuan. Demand for AI glasses could potentially double the demand for power applications. [2][7] - The advanced packaging market is also significant, with Jing Sheng poised to leverage its technology and cost advantages. [2][8] Competitive Advantages - Jing Sheng has a strong competitive edge in the SiC substrate sector due to its expertise in crystal growth technology and equipment manufacturing. The company has successfully produced 12-inch products, a feat achieved by only a few global players. [3][6] - A strategic partnership with Xreal has been established to supply 8-inch and future 12-inch SiC substrates for AI glasses validation and product design. [6] Semiconductor Equipment Business - The company has seen significant growth in new orders for semiconductor equipment, with reported orders exceeding 3 billion yuan. This includes not only manufacturing equipment but also subcontracting for equipment components. [2][10] Challenges in the Photovoltaic Industry - The photovoltaic (PV) industry is currently facing overcapacity and declining profitability, with many segments operating at a loss. Jing Sheng's PV equipment revenue constitutes about 80% of total revenue, but new orders are under pressure due to poor profitability in the silicon wafer sector. [4][11] - The company is promoting superconducting technology, although progress has been slow, and it faces minimal impairment pressure as major clients have already accounted for potential losses. [4][13] Product Insights - Jing Sheng's main PV materials include quartz crucibles and diamond wires. The price of quartz crucibles is at a low point, with the company expected to increase its market share from 40% this year to 60% next year. [4][13] - In the diamond wire segment, tungsten wire is gradually replacing carbon wire as the mainstream material, with the company focusing on self-research to reduce costs. [4][13] Future Outlook - The future application prospects for SiC are broad, particularly in power applications for new energy vehicles. The market for AR glasses and advanced packaging is expected to exceed current power application markets significantly. [9] - As a leading manufacturer of large-size SiC substrates, Jing Sheng's competitive advantages are expected to strengthen with increasing sizes and new applications. [9][10] Additional Important Information - The company is also developing smart factory-related equipment, with a significant portion of its revenue coming from intelligent equipment in the first half of the year. [13] - The overall outlook for Jing Sheng's PV equipment and materials business is positioned at the bottom of the cycle, with potential for performance recovery as the industry stabilizes. [13]
