Introduction to the Main Activities of Investor Relations

1. What is the company's business model for its engineering operations?

The company was established through the restructuring of a state-owned central enterprise design institute, primarily serving clients in the chemical and petrochemical industries. It is actively transforming and expanding into the new energy market. Our business excels in environmental protection, and for many years we have been dedicated to providing customers with one-stop, full-lifecycle engineering technical services—including engineering consulting, engineering design, EPC (engineering, procurement, and construction) contracting, project start-up, and post-completion maintenance. The company itself does not typically engage in equipment or material production, nor in construction and installation services. Instead, during our daily operations, we subcontract the equipment, materials, and construction/installation work required for EPC projects—based on actual project needs—to qualified manufacturing and construction subcontractors who possess the necessary qualifications, manufacturing capabilities, and construction expertise, all selected through a transparent bidding process.

II. What are the company's main clients in the engineering business?

The company's primary customer base includes China Petrochemical Corporation, China National Petroleum Corporation, China Energy Investment Corporation, Datang Group, Sinochem Holdings, CNOOC Group, China Coal Group, China General Nuclear Power Group, China North Industries Group Corporation, Shaanxi Yanchang Petroleum, Wanhua Chemical Group, Hengli Petrochemical, Shenghong Petrochemical, Yulong Petrochemical, as well as numerous other local refining and chemical enterprises that boast strong financial capabilities and excellent creditworthiness.

III. Key Technical Advantages in the Company's Engineering Field

As “ Sulfur Recovery Expert ” , the company's independently developed “ Online Furnace-Free Sulfur Recovery Technology ” Achieve domestically leading and internationally advanced standards; “ Acid Gas Sulfur Recovery and Ultra-Low Emission Technology & Applications for Flue Gas Purification ” After being evaluated and reviewed by the China Petroleum and Chemical Industry Federation, the achievement was deemed to be generally at an internationally leading level. For instance, the company 2024 Disclosure of relevant sections in the annual semi-annual report, as of 2024 Year 6 Month 30 On the day, the company had cumulatively completed the design and general contracting of various sulfur recovery units. 237 Set, total scale of the installation 1255 Ten thousand tons / This year, it is the company that has designed and provided the most turnkey sulfur recovery units domestically.

Meanwhile, the company boasts strong market competitiveness in energy-saving and environmental protection engineering fields such as comprehensive utilization of C4 resources, high-pressure hydrogenation, acidic water vapor treatment, flue gas management, and wastewater treatment. Additionally, through project implementation in new energy sectors like hydrogen energy, molten salt energy storage, and compressed air energy storage, the company has accumulated extensive experience.

The company places great emphasis on enhancing its R&D capabilities and technological strength. Through strategies such as talent development, recruitment, and collaboration, it has assembled a high-caliber technical team with a global perspective. As a result, the company’s technology-focused division is already beginning to yield significant results. Moving forward, the company will fully leverage the engineering division’s pivotal role in bridging the gap between upstream and downstream operations, exploring efficient synergy mechanisms that connect seamlessly with both the technology and industrial sectors. This approach will help establish a closed-loop system integrating R&D, engineering implementation, and industrial operations. By building on these unique strengths, the company is committed to becoming a leader in resource-efficient, technologically differentiated, and premium-quality product offerings. “ Value Enterprise ”。

4. What are the company's main products in its chemical business? And what effective measures has it taken to address the industry's cyclical fluctuations?

The company is currently the largest n-propanol producer in China, a leading domestic enterprise specializing in butanol and octanol residue recovery, and a prominent n-pentanol sales company. It primarily focuses on the research and development of various advanced chemical materials, as well as certain other areas. C3、C4、C5、C8 Production and sales of alcohols (including aldehydes and acids), as well as products such as n-propyl acetate, butyl acetate cellulose, and their derivatives. The company's products are widely used across multiple industries and fields, including pharmaceuticals, agrochemicals, dyes, pigments, coatings, chemicals for information technology, chemical reagents and high-purity substances, food additives, feed additives, catalysts, adhesives, auxiliaries, surfactants, fragrances, and more.

Compared to large, integrated enterprises in the industry, the company enjoys greater flexibility in production and operations due to the absence of specific constraints at the raw-material end. This allows the company to closely monitor product marginal benefits and swiftly shift toward producing high-margin products by adjusting its raw-material strategies—based on short-term and long-term market demands, trends in raw-material prices, evolving product pricing, inventory levels, and other factors—thereby ensuring robust economic performance.

V. Introduce some project cases the company has undertaken in the coal chemical industry.

The company’s engineering business, leveraging its technological strengths, has successively undertaken the basic design and technical service project for the sulfur recovery unit in Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project, as well as the second set of projects for Ningxia Baofeng Energy Group Co., Ltd. 50 Ten thousand tons / The annual coal-to-olefins project's supporting methanol plant sulfur recovery unit process package and design project, as well as the sulfur recovery unit patent technology licensing and technical service project for Shaanxi Coal Group Yulin Chemical Co., Ltd., have been successfully awarded to Guodian Energy Group Jun Dong. 20 Billion cubic meters / Work on process packages and design-related tasks for several new coal-to-gas projects, including the sulfur recovery unit project. Meanwhile, the company has assigned dedicated personnel to closely monitor and coordinate with the progress of coal chemical projects, leveraging its own technological and engineering strengths to actively support the growth of the coal chemical industry.

6. What are the company's incremental projects in the chemical business?

Currently, the company is fully committed to advancing “ Butyric Acid Cellulose Acetate Product Optimization and Upgrade Technical Transformation Project ” Ensure high-quality construction progress. “ Isooctanoic acid ” New production capacity ( 50000 Ton / Year) to be completed and put into operation as soon as possible; the company “ Cellulose Derivative and Its Supporting Equipment Upgrade Project ” Currently, technical feasibility studies and design optimizations are underway, with efforts focused on completing construction as planned. Additionally, the company has integrated R&D resources from universities, research institutes, and enterprises to drive innovation in developing new downstream products centered around aldehydes, alcohols, acids, and esters. This collaboration is now expanding into cutting-edge areas such as new energy, fine chemicals, and advanced materials through collaborative R&D initiatives.
