Summary of the Conference Call for Shijia Photonics Industry and Company Overview - The conference call pertains to the optical communication industry, specifically focusing on Shijia Photonics, a company specializing in optical components such as AWG (Arrayed Waveguide Grating) and MPO (Multi-fiber Push On) connectors [2][3]. Key Points and Arguments - **AWG Product Performance**: The gross margin for AWG products significantly improved, with an increase of over ten percentage points from 2024 to Q1 2025, and revenue growth exceeding 200%. This growth is primarily driven by domestic module manufacturers' demand for cost reduction [2][3]. - **MPO Connector Growth**: MPO connectors experienced a growth rate close to 400%. The gross margin for indoor cables also saw a significant increase of approximately 10%-20%, with revenue growth surpassing 100%. This is attributed to a shift towards high-margin cables for data center applications, mainly supplied to overseas cabling companies [2][3]. - **Competitive Landscape**: In the domestic market, Shijia Photonics faces competition from companies like Tianfu and Guangxun, which primarily use AWG products for their own production. However, Shijia's full-process production capability (BIM) provides a competitive edge in supply chain stability, especially in light of trade wars and tariffs affecting raw material supplies [2][6]. - **Product Development**: The company is actively developing active products, including a CW light source product matrix with power ranges from 70 milliwatts to 1,000 milliwatts, suitable for silicon photonics applications. These products are currently undergoing reliability and performance validation at client sites [2][17]. - **Thailand Factory Expansion**: The commissioning of the Thailand factory has met the origin-switching requirements of cabling customers, resulting in increased orders. Plans are in place to further expand the factory's capacity through leasing and constructing additional facilities [2][19][20]. Additional Important Information - **Market Share Dynamics**: By Q1 2025, the market share between domestic and international module manufacturers for AWG products is nearly balanced at 50-50, with rapid growth observed among domestic manufacturers [2][5]. - **Order Visibility**: The typical order visibility cycle ranges from 3 to 6 months, with larger orders planned for the entire year based on previous quarter forecasts [2][12]. - **Product Customization**: AWG production lines require a certain degree of customization, leading to significant differences in gross margins, which can range from 45% to 90% depending on the product [2][10][11]. - **Emerging Product Lines**: The company is also developing AUK products for short-distance modules, which are integrated into silicon photonics units and are expected to see substantial domestic order volumes in the future [2][15]. This summary encapsulates the critical insights from the conference call, highlighting Shijia Photonics' performance, competitive positioning, and strategic initiatives within the optical communication industry.
