Revenue and Cost Analysis - Revenue growth was primarily driven by increased sales of germanium products, with a notable rise in prices due to higher raw material costs [4]. - Operating costs increased by 35.53%, largely due to rising unit costs of key products [5]. - Sales expenses surged by 77.82% as the company intensified market expansion efforts [5]. Balance Sheet Changes - Accounts receivable increased by 49.58%, attributed to higher sales of various germanium products [2]. - Short-term borrowings rose by 78.66%, indicating increased bank loans [2]. - Contract liabilities grew by 58.93%, reflecting an increase in prepayments received [2]. Cash Flow and Investment - Operating cash flow per share was -0.2 yuan, a decrease of 58.73% year-on-year, indicating cash outflows due to increased raw material purchases [1][8]. - Investment cash flow showed a significant decline of 188.96%, primarily due to higher cash payments for fixed asset acquisitions [8]. R&D and Future Outlook - R&D expenses increased by 86.41%, reflecting ongoing projects in semiconductor materials and germanium products [6][7]. - The company’s reliance on R&D for performance improvement suggests a focus on innovation and product development [10]. Debt and Liquidity - The company maintains a healthy cash position, but the cash flow situation raises concerns, with a cash asset to current liabilities ratio of only 60.03% [9][11]. - The debt situation is also a point of concern, with a significant portion of liabilities related to interest-bearing debts [11]. Market Position - The company’s performance is cyclical, with historical data indicating periods of weak returns on invested capital (ROIC) [8]. - The primary reliance on R&D-driven growth necessitates careful monitoring of underlying market conditions and product demand [10]. Fund Holdings - The largest fund holding Yunnan Ge Industry is the Guotou Ruijin Economic Driven Mixed A Fund, which has increased its position recently [11].

Core Viewpoint - The company is focusing on increasing the production capacity of 8-inch substrates rather than mass-producing 12-inch substrates due to the current state of technology and market conditions [1] Group 1: Production Capacity and Technology - The company has achieved self-controlled technology for 6-12 inch conductive silicon carbide crystal growth [1] - The expansion of 8-inch conductive silicon carbide substrates is primarily aimed at high-power applications in electric vehicles, high-voltage charging, energy storage, and rail transportation [1] - The company has stabilized mass production of 8-inch optical-grade crystals and is accelerating the industrialization verification of 12-inch optical-grade substrates [1] Group 2: Market and Ecosystem - The upstream and downstream ecosystem for 12-inch silicon carbide is still in the early verification stage and does not yet support large-scale industrialization [1] - The company will advance the production of 12-inch substrates based on the maturity of the supply chain and customer demand [1] Group 3: Future Investments and Strategic Focus - The company plans to continue increasing investment in the research and development of compound semiconductor materials to maintain a technological lead [1] - The focus is on providing reliable and leading key material support for strategic emerging industries such as electric vehicles, photovoltaics, 5G communication, and AR glasses [1]
