Summary of Lianrui New Materials Conference Call Company Overview - Lianrui New Materials specializes in spherical silicon powder, primarily used in epoxy molding compounds (EMC), accounting for approximately 50% of revenue, with a selling price of around 15,000 yuan/ton. Angular silicon powder is mainly used for copper-clad laminates (CCL), contributing about 20% of revenue, priced between 3,000-4,000 yuan/ton. Ordinary alumina powder is used for heat dissipation in new energy vehicles, also accounting for about 20% of revenue [2][3][4]. Market Position - Lianrui holds a leading position in the global CCL market with a market share of approximately 25%. The company has a broad customer base, including Panasonic and Doosan, but has limited cooperation with Taiguang due to historical equity relationships [2][4][8]. Product Development and Upgrades - The upgrade of CCLs is increasing the importance of silicon micro-powder and alumina powder. Starting from the M6 generation, spherical silicon micro-powder is used, with M7 using sub-micron spherical silicon micro-powder (priced at 100,000 yuan/ton), M8 using both sub-micron and chemical spherical silicon micro-powder (over 200,000 yuan/ton), and M9 fully adopting chemical spherical silicon micro-powder [2][6][14]. Revenue Growth and Projections - Lianrui's revenue growth is projected to double in the coming years, driven by increased demand for higher-grade spherical silicon micro-powder as M8 and M9 CCLs gain traction. The high-grade silicon micro-powder project is expected to produce 3,600 tons annually at an average price of 200,000 yuan, generating a total output value of 720 million yuan. The alumina powder project for new energy vehicles is expected to produce 16,000 tons annually at an average price of 20,000 yuan, generating a total output value of 320 million yuan [4][10][11]. Competitive Advantages - Lianrui's core competitiveness lies in its product structure and market coverage. The company has a strong reputation for product quality, slightly lower prices compared to overseas competitors, and excellent service and supply capabilities, which have strengthened customer loyalty even during the pandemic [3][9][12]. Industry Trends and Future Outlook - The demand for higher-grade silicon micro-powder is expected to rise as the CCL market evolves. Lianrui is positioned to benefit from this trend, especially as overseas clients like Panasonic and Doosan deepen their cooperation with the company [8][15]. The average compound growth rate for Lianrui's sales over the past few years has been between 20% and 25%, with a minimum growth rate of 8% during economic downturns and up to 40% in favorable years [10][11]. Valuation and Market Sentiment - Lianrui has maintained a high valuation, with a PE ratio between 30 and 40, even during periods of lower industry sentiment. This is attributed to its strong competitive position and growth potential, justifying a premium valuation despite lower stock price increases compared to other materials [12][15]. Conclusion - Lianrui New Materials is well-positioned for future growth, driven by industry upgrades and strong customer relationships. The company's focus on high-quality products and strategic market positioning will likely enhance its competitive edge and financial performance in the coming years [10][11][16].
