The implementation and effect evaluation of the 2024 Action Plan for "Improving Quality and Efficiency and Focusing on Return" is reported as follows:

I. Focusing on the Company's Core Business and Continuously Enhancing Core Competitiveness

In 2024, the Company's management adhered to a prudent operational philosophy, remaining anchored to and continuously deepening its core business. Amid a complex and volatile market environment, the Company maintained strategic determination, effectively mitigated market risks through precise control of development pace, and ultimately achieved revenue scale for fiscal year 2024 basically on par with the same period of the previous year, establishing a solid foundation of high-quality development for the Company's long-term growth.

The Company's operational team systematically enhanced the efficiency of the entire project engineering process, optimized supply chain procurement cycle control, and implemented a "modular" production management system, comprehensively building precise implementation capabilities covering large and medium-sized cleanroom and electromechanical engineering projects. Leveraging the advantages of full industry chain resource integration, the Company has formed an engineering closed loop from design refinement and prefabrication to on-site assembly, ensuring that customers across multiple sectors receive efficient responses and quality assurance in cleanroom construction and electromechanical system integration, continuously fulfilling performance commitments at key project milestones.

Southeast Asia has become a core region for the expansion of the Company's overseas business map. The Company's subsidiaries in Malaysia, Indonesia, Thailand, Vietnam, and other countries, with solid domestic support, have achieved efficient complementation and synergistic supply of raw materials, technology, and human resources. In Southeast Asian countries, the Company's business is gradually expanding from breakthrough points to a tightly connected network, with subsidiaries complementing and advancing together, creating increasingly flexible and elastic business development space.

In terms of enhancing technical services, the Company, taking the cultivation of core enterprise competitiveness as its starting point, has adopted multiple R&D models such as independent research and development and industry-university-research cooperation to improve its internal R&D system construction. Guided by "intelligence, green, and

high-end" principles, through the implementation of key research and development projects such as efficient air purification technology research, intelligent cleanroom management systems, cleanroom green building materials research, and cleanroom energy-saving technology research, the Company provides customers with more efficient, stable, environmentally friendly, and convenient cleanroom solutions.
