Dinglong shares: The recent international situation has not affected the company's production materials for wafer photolithography.

Dinglong Group stated at the performance briefing on April 2 that for high-end wafer photoresist, the company has independently researched and developed and prepared the necessary functional monomers, main resins, and other core raw materials, establishing a stable and controllable upstream raw material system. This layout effectively ensures the stable supply of core raw materials, significantly reducing external dependency risks. Therefore, the recent international situation has not affected the company's production of wafer photoresist raw materials. The company's independent research and development of core raw materials, highly matched with its own photoresist product process, has formed a synergistic advantage in purity control and performance adaptability, laying a solid foundation for stable production and performance optimization. Regarding photoresist for OLED flexible displays, the company has become the core supplier for major domestic display panel manufacturers, leading in domestic market share with strong market competitiveness and customer stickiness. In terms of competition landscape, the companys comprehensive competitiveness is evident based on its technological accumulation in the material field, product performance advantages, and deep cooperation with customers.
