Summary of Conference Call Records Company and Industry Overview - The analysis focuses on **炬光科技 (Juguang Technology)**, a company operating in the **optical communication** and **semiconductor** sectors, with a particular emphasis on its **OCS (Optical Communication Systems)** business segment [1][2]. Key Insights and Arguments - **Valuation Breakdown**: The company’s valuation is segmented as follows: - Plug-and-play modules: €60-70 million - OCS: €100-120 million - CPO (Chip-on-Board): €150 million - Other businesses: €100 million - Total estimated valuation: €450 million [1] - **Market Potential**: The total addressable market (TAM) for the industry in 2027 is projected to be €60-70 million. Assuming a 15% market share, this translates to a net profit of €2-3 million, leading to a price-to-earnings (PE) ratio of 20-25x, resulting in a valuation of €60-70 million [1]. - **Comparative Valuation**: Compared to other OCS companies, Juguang Technology is considered relatively undervalued. Other OCS companies are typically valued based on their end-state estimates, with projections for 2030 estimating 300,000 OCS units. If Juguang captures a 30% market share, with a unit value of €12,000-€13,000 and a net profit margin of 30%, this could yield profits of €3-4 million, leading to a valuation of approximately €100-120 million at a PE of 25-30x [1]. - **Competitive Landscape**: The competitive environment may be better than expected, with the market not fully pricing in the potential for scaling up. The company is well-positioned in the "out" domain and is expected to have similar potential in the "up" domain [1]. - **Profit Projections**: - For the "out" domain, with a forecast of 100,000 units in 2027, a unit value of €50,000, a 20% market share, and a 30% net profit margin, the projected profit is €3 million, leading to a valuation of €120 million at a PE of 40x [2]. - For 2030, with a forecast of 300,000 units and a unit value of €40,000, the projected profit is €7-8 million, resulting in a valuation of €150 million at a PE of 20x [2]. - **Stability in Related Industries**: Traditional industrial and semiconductor sectors are stabilizing, with automotive applications and healthcare growing at around 10%. Consumer electronics are expected to start contributing to revenue from Q3 2026 [2]. - **M&A Impact**: The negative impact of mergers and acquisitions is expected to diminish, with the SMO production line successfully relocated from Switzerland to Shaoguan, achieving profitability. The Heptagon acquisition is anticipated to break even within 6-8 quarters post-acquisition [2]. - **Market Sentiment and Performance**: The current market sentiment is cautious regarding the company's performance. However, the presence of CPO beta is expected to provide ongoing support for the stock price. The period before April is seen as relatively safe, with expectations of increased revenue from optical communications in the second half of the year, which could lead to profitability [2]. Additional Important Points - **Investment Strategy**: The suggested trading strategy involves buying during significant dips and smaller dips, with opportunities arising from daily long lower shadows or short-term corrections. Continuous monitoring and attention are recommended [3].
