Investment View

Thesis: From Component Supplier to Integrated Solution Partner

Jiangyin Haida Rubber and Plastic is undergoing a transformative phase, evolving from a traditional manufacturer of rubber seals into a technology-driven provider of sealing and vibration damping systems for the next generation of infrastructure and mobility.

1. The "Moat" is Deepening:
Haida’s core strength lies not just in manufacturing, but in material science. The ability to modify rubber compounds to meet specific, demanding requirements (e.g., extreme temperatures for PV, chemical resistance for hydrogen, acoustic perfection for luxury autos) creates high switching costs for customers. This R&D-centric approach ensures that Haida remains indispensable to its clients, protecting margins and ensuring recurring revenue.

2. Diversification as a Stability Engine:
The Company’s four-pillar strategy (Rail, Auto, Construction, Shipping) provides remarkable stability. When one sector faces headwinds (e.g., construction slowdown), others (e.g., auto exports or rail maintenance) often remain resilient. The addition of New Energy (PV, Wind, Storage) adds a high-growth fifth pillar that is less correlated with traditional economic cycles, further smoothing earnings volatility.

3. Internationalization is Key to Valuation Re-rating:
Historically, Chinese material stocks have traded at discounts due to perceptions of being domestic-focused and low-margin. Haida’s successful establishment in Romania and partnerships with global leaders like LONGi challenge this narrative. As international revenue grows, Haida should command a higher valuation multiple, akin to global specialty chemical peers, reflecting its status as a global competitor.

4. Financial Quality is Improving:
The divergence between revenue growth (13%) and profit growth (43%) in 2025 is a critical indicator. It signals that the Company is not just selling more, but selling better. Higher-value products, improved operational efficiency, and scale economies are flowing through to the bottom line. If this trend continues, earnings per share (EPS) growth will likely outpace revenue growth, driving shareholder value.

Strategic Recommendations for Investors

Monitor the PV Ramp-Up: Investors should closely track the volume and margin contribution from the LONGi buckle short-frame orders in upcoming quarterly reports. Successful scaling here will be a primary validator of the growth thesis.
