• Resource Barriers: Monopoly of Scarce Resources in Core Areas Production bases are laid out in Guangdong, Hunan, Thailand, etc., with high-end HDI equipment (such as Japanese Disco laser drilling machines) being globally scarce, and Shenghong has secured supply in advance to ensure delivery.

2. R&D and Innovation Investment: High Investment Supports Technological Leadership

• From 2021 to 2024, R&D expenses exceeded 1.2 billion yuan, with a research expense ratio maintained at 4%-5% (higher than the ordinary PCB industry at 2%);
• The R&D team has over 1,362 people (accounting for 9.87% of total employees), with core personnel from Huawei, Foxconn, etc., possessing deep expertise in HDI and high-frequency materials;
• Technology Reserves: Already laid out for 10-stage 30-layer HDI and quantum computing chip substrates, with HDI shipments expected to account for 60% of the domestic market by 2025, laying the foundation for future growth.

4. Management Team and Governance Structure

1. Management Capability: Rich Industry Experience, Accurate Strategic Vision

• Core Executive Background: A Dual-Driven Team of Technology and Industry
• Chairman Chen Tao: Has 20 years of experience in the PCB industry, leading the company’s transition from consumer electronics to AI computing power, with accurate judgment on NVIDIA’s technology roadmap;
• General Manager Zhao Qixiang: Former senior executive at Baicheng Electronics, outstanding in the implementation of HDI technology, driving the Thailand base to start production 6 months ahead of schedule.
• Management Stability: Core Team in Position for Over 5 Years Since its listing, there have been no significant changes in core positions such as chairman, general manager, and CFO, ensuring strong strategic consistency and avoiding the risk of frequent leadership changes.

2. Corporate Governance: Reasonable Shareholding Structure, Strong Compliance

1. Culture and Values: Strong Practicality, Aligning with Industry Trends

• The core values are “Innovation-Driven, Responsibility-Oriented,” with specific implementations: ① Innovation: Establishing the “Technology Breakthrough Award,” with employee innovation proposals saving over 20 million yuan annually; ② Green: Promoting the construction of “Zero Carbon Factories,” with 50% of the Guangdong base using green electricity, and carbon emissions per unit of output decreasing by 12%; ③ Responsibility: Participating in the “Rural Revitalization” project, building 50 photovoltaic irrigation systems in Africa.

2. Employee Evaluation: Strong Salary Competitiveness, Work Intensity Matching Industry Characteristics

• Salary Levels: Salaries for technical positions are significantly higher than the manufacturing industry average (e.g., HDI engineers earn 20-35k per month), while production positions earn 6-10k per month (including overtime), with benefits including five insurances and one fund, and year-end bonuses (13-15 months);
• Work Environment: R&D positions implement a “flexible work system,” with a peak season overtime rate of about 30% (lower than the industry average of 50%), and employee satisfaction rating of 4.0/5 (higher than the industry average of 3.8/5).

6. Risks and Compliance

1. Legal and Compliance Risks: Low Risk, No Major Violations

• No major lawsuits in the past 3 years (only a 477 million yuan equipment sales contract dispute with Hesheng Silicon Industry, which has entered judicial proceedings);
• Compliance: Complies with China’s “Data Security Law” and “Export Control Law,” adheres to local labor laws in factories in Europe and the United States, with no environmental penalty records.

2. Potential Crises: Attention Needed on Three External Risks

• Customer Concentration Risk: The top five customers account for 51%, with NVIDIA and Tesla alone accounting for over 40%; the company is mitigating risks by expanding its customer base to include AMD and Intel (with revenue from small and medium customers expected to increase to 30% by 2025).
• Technology Replacement Risk: If silicon photonics technology replaces lithium niobate modulators, it may lead to depreciation of existing equipment; the company is simultaneously laying out silicon photonic modulators and collaborating with the Chinese Academy of Sciences to develop new materials.
• Industry Competition Risk: The HDI industry is expected to have a 20% oversupply in 2025, increasing the risk of price wars; the company is responding with differentiated products (such as integrated thin-film modulators) and expansion into overseas markets (European base).

7. Customer and Market Reputation

1. Customer Satisfaction: Stable Cooperation with Leading Customers, High Repurchase Rate

• Enterprise Customers: Over 3 years of collaboration with NVIDIA and Tesla, with a repurchase rate exceeding 80%; in Q1 2025, new AI server PCB orders exceeded 1.2 billion yuan, with high customer replacement costs;
• Overseas Customers: Supplying automotive electronics PCBs to Bosch in Germany, with customer feedback stating “delivery cycles shortened by 20%, equipment failure rate below 1%”, and an overseas business renewal rate exceeding 85%.

2. Public Sentiment and Reputation: Predominantly Positive Image, No Major Negatives
