Industry of the Company during the Reporting Period Looking back on last year, although the world economy started recovery, the growth was still slow and unbalanced, and the persistent turmoil in the international situation and the persistent negative impact of the pandemic on the supply chain still significantly dragged down the pace of recovery. In the face of multiple difficulties, China has achieved high-quality and steady development, and made a series of progress in the construction of modern industrial system. 2023 is the first year to fully implement the spirit of the 20th National Congress of the Communist Party of China, and it is also a crucial year to carry out the "14th Five-Year" Plan. The annual GDP exceeds RMB 126 trillion, with a year-on-year increase of 5.2%, ranking among the world's major economies, and its contribution rate to world economic growth is expected to exceed 30%, making it the biggest engine of world economic growth. China petrochemical industry has a complete industrial chain with great development resilience and potential, and its long-term positive fundamentals have not changed. In the past year, the petrochemical industry accelerated its recovery, production and supply increased steadily, and market demand gradually improved. (1) Global economy During the reporting period, the global economic recovery faced multiple dilemmas. Despite the aggressive rate hike by the Federal Reserve Board and the lack of endogenous motivation in the European economy, the world economy still did not get rid of the "stagflation" dilemma of high inflation and sluggish demand. In 2023, the world economy showed a weak recovery trend, with a global inflation rate of 7%, and a global GDP growth rate of only 3%. The external environment was more complicated and changeable due to multiple factors, such as great power game and geopolitics.

GDP increased by 4.5%, 6.3%, 4.9% and 5.2% respectively in the four quarters of 2023, showing a trend of low in the beginning, high in the middle and stable in the end. The profits of industrial enterprises have recovered since August, but due to the drag in the first half of the year, a negative growth was recorded throughout the year. In 2023, the total profits of industrial enterprises above designated size in China reached RMB 7.69 trillion, with a year-on-year growth rate of -2.3% and a previous value of -4.0%, maintaining a recovery trend. Although industrial enterprises are facing difficulties such as the world economic downturn, blocked industrial exports, insufficient domestic demand and falling prices of industrial products, they have continued to recover overall with the gradual effectiveness of various policies and measures to promote the development of manufacturing industry.

The poor performance of petrochemical industry is mainly due to the large price drop of crude oil, natural gas and most 12 / 269 Full Text of 2023 Annual Report chemical products. In terms of subdivided sectors in petrochemical industry: the oil and gas sector realized an operating income of RMB 1.44 trillion, down 3.9% year-on-year; and a profit of RMB 301.03 billion, down 15.5% year- on-year. The oil refining sector realized an operating income of RMB 4.96 trillion, up 2.1% year-on-year; and a profit of RMB 65.6 billion, up 192.3% year-on-year. The chemical sector achieved an operating income of RMB 9.27 trillion, down 2.7% year-on-year; and a profit of RMB 486.26 billion, down 31.2% year-on-year. Because of the low base in 2022, the operating income and profit of the oil refining sector in the three major sectors have both increased, while the operating income and profit of the oil and gas sector and chemical sector have decreased, which is related to the high base of the oil and gas sector and the chemical sector in 2022. In order to realize the healthy development of the petrochemical industry, in 2023, the National Development and Reform Commission, the Ministry of Industry and Information Technology and other relevant ministries and commissions successively promulgated a number of industrial policies closely related to the petrochemical industry. These policies help stabilize the growth of the petrochemical industry, accelerate the structural adjustment and intensive cluster development of the industry, and consolidate and strengthen the supply chain of the industrial chain, thus laying a good foundation for the high-quality development of the industry. S/N Time Policy 1 March Guide for the Establishment of Energy Industry Standard Plan in 2023 2 March Green Industry Guidance Catalogue (2023 Edition) (Draft for Comments) Benchmark Level and Standard Level of Energy Efficiency in Key Industrial Areas (2023 3 June Edition) 4 August Work Plan for Steady Growth of Petrochemical Industry Guiding Opinions on Promoting Green, Innovative and High-quality Development of Oil 5 October Refining Industry 6 November Construction Plan for National Peak Carbon Dioxide Emissions Pilot In 2023, the petrochemical industry has made new breakthroughs and new progress in scientific and technological innovation, green and low-carbon transformation and digital upgrading, deepening international cooperation, cultivating world-class enterprises and modern industrial clusters, research on industrial policies and major issues, etc. However, there is still a certain gap from the goal of high-quality development, and the shortage of high-end products and high-performance materials has not improved.

The Company has participated in the formulation of the national standards for the energy consumption limit per unit product of this product. Several The large-scale device greatly reduces the investment cost per unit product. Besides, the continuous improvement of new Leading Introduction core technologies and new equipment has shortened the process. For example, the oxidation unit adopts pressure filter instead of PTA position in and technical vacuum filter, dryer, intermediate silo and other auxiliary systems; The refining unit adopts pressure filter, which changes two- China innovation personnel stage separation into one-stage separation. Compared with the traditional process, the number of equipment is reduced, the maintenance cost is also greatly cut, the reliability of equipment is improved, and the stability of the device is improved accordingly. At present, the pressure filter technology has been well applied in PTA plant and has become a development trend at 16 / 269 Full Text of 2023 Annual Report present. In addition, the application of new materials in PTA production has further reduced the investment cost. At present, dual-phase steel is used to replace part of titanium alloy and 317L, which reduces the material cost. In terms of material consumption, all PTA patent manufacturers have done a lot of work in optimizing oxidation reaction conditions, adjusting catalyst ratio, increasing catalyst recovery, PTA mother liquor solid recovery, methyl acetate recovery and so on, and all of them have been successfully applied to industrial devices. The use of these optimizations and new technologies greatly reduce the material consumption of PTA production. In terms of energy consumption, as the oxidation reaction is exothermic, a lot of heat will be released during such reaction. At present, PTA patent technologies use the reaction heat to generate low-pressure steam of different grades for air compressors and other low-pressure steam users in the device (such as dehydration tower). By using this method, the oxidation tail gas at the top of the oxidation reactor is cooled and energy is recovered; Hydrogenation reaction is a high-temperature and high-pressure reaction. During the crystallization process, with the gradual reduction of pressure, a large number of steam with different grades will flash out, which is basically used to heat the feed of hydrogenation reactor, and can be heated to about 260°C. Oxidation tail gas is high-pressure gas, part of which is used as the driving power of air compressor, and the rest is used for conveying gas and inert gas in the device to users. In addition, the process arrangement is optimized as much as possible, to make full use of the heat exchange of hot and cold process fluids. Through the above measures, PTA basically does not need to supply low-pressure steam from outside at present, but only needs a certain amount of high-pressure steam to heat the feed of hydrogenation reactor from about 260°C to about 286°C; The drive of the air compressor does not need to supply energy from outside. In order to reduce energy consumption, some other measures have been taken, such as increasing the feed concentration of hydrogenation reactor and increasing the circulation of mother liquor in TA unit. At present, the comprehensive energy consumption of PTA has been greatly reduced, and the energy consumption of products is better than the advanced value of national standards. Maximum output, maximum conversion rate and minimum energy consumption; By tapping the equipment potential, achieve the purpose of improving production and efficiency without increasing energy consumption; Improve energy utilization rate and Several reduce production cost; Eliminate the filter blockage, waste of labor, save the cost of bagging, and bring considerable economic Introduction Large-scale core benefits to the company; Make the basic magnesium sulfate whisker, tetrapod-like zinc oxide whisker, magnesium salt whisker, Polyester and application technical β-type silicon nitride whisker, melamine cyanurate, microencapsulated red phosphorus flame retardant, ethylene glycol, etc., into innovation personnel flame retardant and anti-dripping whisker glycol solution through a certain manufacturing process by using the company's patented technology; Add the flame-retardant and anti-dripping whisker glycol solution into the slurry preparation tank, and prepare the flame-retardant and anti-dripping polyester through esterification, pre-polycondensation and final polymerization.

Engaged in chemical fertilizer industry □Yes No Engaged in pesticide industry □Yes No Engaged in chlorine-alkali and soda ash industry □Yes No III. Analysis of Core Competitiveness As one of the leading enterprises in the petrochemical industry with leading comprehensive strength in China, the Company’s core competitiveness is mainly reflected in the following aspects: (1) Complete industrial synergistic advantages After years of development and improvement, the Company has seized the opportunity of industrial adjustment, achieved rapid growth, and formed the development strategy of “from a drop of oil to everything in the world”. Through the extension of the industrial chain, the Company has effectively reduced the business cost, realized the mutual support of upstream and downstream sectors, and also improved its sustainable 22 / 269 Full Text of 2023 Annual Report profitability and risk resistance. For example, ZPC can supply PX as raw material for PTA production to shareholder units and related companies, and ethylene glycol as raw material for downstream production of polyester bottle chips, films and chemical fibers. The release of ZPC's production capacity has greatly supplemented the mutual supply demand of raw materials for the development of the Company's industrial chain and realized self-supply and self-sufficiency of raw materials. The interconnection of Zhoushan Green Petrochemical Base and Ningbo Petrochemical Base can realize the coordinated development of both Ningbo and Zhoushan bases, and pipeline transportation greatly reduces the risk and cost of ship transportation and land transportation; A large number of light hydrocarbon raw materials by-products from Ningbo Petrochemical Base are transported to Zhoushan Green Petrochemical Base through pipelines, which can be used as high-quality ethylene raw materials. Surplus oil products from Zhoushan Green Petrochemical Base can be transported to Ningbo Petrochemical Base as high-quality raw materials for aromatic hydrocarbon production. The construction of ZPC Project has supporting facilities that can meet the demand of crude oil supply in the two phases of the project. The total storage capacity of Mamu crude oil depot and Yushan Island crude oil depot has reached 4.6 million m which is the largest storage capacity among domestic refining and chemical facilities. As the most concentrated resource allocation base for oil and gas enterprises in China, the Zhejiang Free Trade Zone has an oil depot capacity of more than 30 million m including Huangzeshan Island, Cezi Island, and Waidiao Island. Most of the oil pipeline networks are interconnected, making local transportation available. (2) Remarkable location competition advantages The Company’s production bases are located along the eastern coastline of China, including the “Circum- Bohai Sea Economic Zone” in Dalian City, Liaoning Province; the “Yangtze River Delta Economic Circle” in Ningbo City, Zhejiang Province; the “Belt and Road Economic Belt” and the “Maritime Silk Road” in Haikou City, Hainan Province. Each production base of the Company is adjacent to high-quality ports, connected with canals and equipped with complete wharf facilities. The main raw materials and other auxiliary raw materials required for production can be unloaded and stored at the chemical material wharf built or rented by the Company, which has provided convenient transportation of bulk raw materials and inventory adjustment. ZPC Project is located in the concentrated consumption area of oil products and chemical products, with the key products marketable. The target market of chemical products is mainly East China and South China, where the economy is the most developed with the most active downstream consumption market for petrochemical products, and whose related industries such as downstream plastic product processing industry, light industry and daily chemical industry are developed, with strong market acceptance for bulk petrochemical products. Refined oil has many sales channels and enjoys strong policy support and obvious competitive advantages. The Ministry of Commerce officially approved granting ZPC the export qualification of non-state- owned trade refined oil. As the first private refining and petrochemical enterprise to obtain export permission, 23 / 269 Full Text of 2023 Annual Report ZPC took the lead in opening sales channels in Southeast Asia. In the face of the excess supply of domestic refined oil, this export permission given to ZPC has become more valuable. (3) Excellent strategic layout advantages The Company, with inherent strong market sensitivity and flexible decision-making mechanism, can not only keep a close eye on the market, but also make timely and accurate adjustments to the strategy and seize the preemptive opportunities of the market under its own mechanism advantages of fast pace and few links. The management has a keen sense of investment, accurate timing for project operation and excellent investment and financing capacity. The Company started from polyester chemical fiber, and after years of development, it has formed a good foundation. With the full-scale operation of the 40 million tons/year refining and chemical integration project of its subsidiary in early 2022, ZPC has become the largest single refinery in the world. Relying on the world’s largest single-unit 40 million tons/year refining and chemical integration project of ZPC, the Company has accelerated the layout of downstream new chemical materials, aimed at the field of new energy and high-end materials, and has deployed a number of new energy and new material products such as EVA, POE, DMC, PC and ABS, continuously enriching its product chain. With the steady progress of new projects, the Company’s production capacity of new energy materials, renewable plastics, special synthetic materials, and high-end synthetic materials will be expanded in an orderly manner, and the transformation of new materials will be gradually accelerated. (4) Strong R&D and innovation advantages The Company upholds a technological R&D pattern driven by both independent innovation and cooperation. We have established many world-class R&D platforms, including a high-tech R&D center, a workstation for academicians and experts, an enterprise technology center, and a post-doctoral science and research workstation. Moreover, we engage in active technology exchanges and discussions and promote industry-university-research collaboration to acquire resources from universities, the community, and the Company. With all sectors of society, we jointly promote our research capabilities and technological advancement and together create an innovation ecosystem that is open, healthy, and cooperative, where everyone can benefit. In recent years, the Company has continuously stepped up scientific research cooperation with domestic and foreign countries and increased its R&D investment year by year to maintain a leading level in the industry. The Company's main manufacturing subsidiaries are all national high-tech enterprises with strong research and development strength and rich process operation experience accumulated during long-term production management, which have gathered the strength of "production, learning, research and use" at home and abroad, carried out research and development with independent innovation, and established an integrated achievement improvement platform for laboratory innovation, small test, pilot test and industrial demonstration production, and overcome the disadvantage that it is difficult to incubate and transform related achievements although with basic research by other research institutes in China relying on the Company's flexible system and mechanism 24 / 269 Full Text of 2023 Annual Report and complete industrial chain advantages, breaking through the final ceiling from scientific research achievements to industrial promotion and application, boosting industrial technological innovation and upgrading, seizing the technologically leading position, and promoting the Company's high-quality development in the terms of technological independence, raw material diversification, high-end products, green production and intelligent industry. (5) Rich human resources advantages Focusing on the construction of corporate culture, the Company has formed a favorable working atmosphere and strong corporate cohesion. The Company has also trained a group of stable core management, R&D and technical talents through internal training and introduction. The Company attaches importance to the cultivation of on-the-job staff. Based on reality and comprehensive planning, the Company is constantly broadening the staff selection platform and formulating an effective incentive mechanism. To maintain the practical and effective work of the staff, the Company has improved the benefits of employees, optimized the professional title assessment system, and clarified the promotion standards and incentives.

ZPC With the goal of building a "private, green, international, trillion-level and flagship" base, ZPC's refining and chemical integration project has been planned and unified at one time. At present, it has formed a world- class refining and chemical integration base with a processing capacity of 40 million tons/year for oil refining, 8.8 million tons/year for paraxylene and 4.2 million tons/year for ethylene, among which the single scale for hydrogenation, reforming and PX is the largest in the world. The project is designed to maximize the refining and chemical integration, provide high-quality raw materials for downstream chemical devices, maximize the production of aromatic hydrocarbons (PX) and chemical products, and minimize the output of fuel. The yield of fuel is lower than the industry average, with outstanding effect of reducing oil and increasing chemical. Meanwhile, through the optimal utilization of energy resources such as steam and water, and full use of the low- temperature waste heat of the device, it builds the world's largest thermal seawater desalination device to realize 30 / 269 Full Text of 2023 Annual Report energy saving and emission reduction. The refining and chemical integration rate of the project ranks first in the world, far higher than the average level of petrochemical industry integration in China, and the scale and integration degree of the base are at a leading position in the world. ZPC's crude oil has strong adaptability, and can be stored according to light, medium, heavy and acid, transported separately and refined separately. Combined with blending means, it can process 80%-90% of the global crude oil, which greatly enhances its adaptability to oil price fluctuations and offers obvious advantages compared with other domestic leading enterprises. It has flexible product structure, and mature and reliable technology, and its main device scale and technical and economic indicators represent the most advanced level worldwide. As a result of one-time overall planning, oil refining, aromatic hydrocarbon and ethylene fully demonstrate the concept of "molecular oil refining" and make the best use of the material. All olefins are deeply processed into chemicals with high import dependence, which makes them have stronger ability to cope with the industry cycle. As the upstream industry of the polyester industry chain, ZPC has successfully established the last link of the whole process from a drop of oil to a piece of fiber for the Company, and formed the great advantage of upstream and downstream integration of the polyester industry. ZPC is located in Zhoushan, a part of East China, which is the main consumer of terminal chemicals. The Yangtze River Delta contains about 70% of China's production capacity of plastics and chemical fibers, with obvious regional advantages. Located in Zhejiang Free Trade Zone, ZPC enjoys various preferential policies in the free trade zone and has continuously obtained the export quota of refined oil; Yushan Island, where it is located, is an uninhabited island. Therefore, it is convenient for development and utilization, and will have little impact on the surrounding society and broad development space in the future; Being close to the consumer market, ZPC enjoys a prominent position advantage as a sea-land hub at the Ningbo-Zhoushan port with convenient access to bulk materials and products, and a significantly low transportation costs. 3.2. Zhongjin Petrochemical Zhongjin Project, which was put into operation in August 2015, is an aromatic hydrocarbon combined plant currently in service with leading single scale in the world. This project pioneered the process of making aromatic hydrocarbon products with fuel oil (cheaper than naphtha) as raw material, and adopted a new technical route, which can solve the shortage of global naphtha supply, greatly save the procurement cost of raw materials, introduce the concept of "circular economy", and innovatively use the by-product hydrogen to process fuel oil into naphtha. The new disproportionation catalyst jointly developed by Zhongjin Petrochemical and Tongji University has been successfully applied for the first time in ZPC 2# disproportionation unit (3.5 million tons/year). The catalyst has the excellent characteristics of "three highs", namely high space velocity, high yield and high conversion and utilization rate of heavy aromatic hydrocarbon, and has good operation stability, whose comprehensive performance and technical indicators have reached the advanced level in the world at present, 31 / 269 Full Text of 2023 Annual Report realizing import substitution, which reflects the staged progress of the Company's scientific research and innovation ability and level, and is of great significance for continuously improving the technical level of production equipment, improving the conversion and utilization efficiency of raw materials, reducing consumption and production costs, and realizing the aromatic hydrocarbon production from large to strong and achieving green efficiency. 3.3. Rongsheng New Materials (Zhoushan) As the expansion area of Zhoushan Green Petrochemical Base, relying on ZPC and Ningbo Zhongjin Petrochemical, it extends the industrial chain downstream and develops fine chemicals and new chemical materials. The company focuses on developing downstream products of the existing industrial chains of ZPC and Zhongjin, to achieve the value-added and efficiency increase in raw materials of Zhongjin and ZPC.

At present, the preliminary work is progressing in an orderly manner. 4. PTA sector Since the establishment of the first private PTA production line in 2002, the Company has insisted on independent innovation, successively developed and built the first domestic PTA process package and production equipment with independent intellectual property rights, and realized the first domestic application of core equipment such as large-scale oxidation reactors and high-speed pumps, which changed the long-term dependence of China's PTA industry on the introduction of complete sets of foreign patented technology, and promoted a large number of domestic equipment manufacturers to achieve leap-forward development. At the same time, we have continuously carried out technical transformation on existing equipment to improve production efficiency and product quality, and at the same time continuously optimized raw material consumption to ensure efficient use of resources. Meanwhile, the Company has steadily promoted the launch of new production capacity, on the one hand, to meet the growing market demand, and on the other hand, to stabilize the Company's leading position in the polyester industry. 5. Polyester sector With the general policy of "safety and environmental protection, quality improvement, cost reduction and benefits increase", the Company focuses on strengthening pandemic prevention and control, implementing hidden danger treatment, boosting process optimization and promoting lean production management. Yongsheng Technology's 250,000-ton functional polyester film expansion project has been successfully put into production, and the company's annual polyester film production capacity has reached 430,000 tons, ranking the top four in China. The Company's PTA production enterprises make full use of the advantages of the 32 / 269 Full Text of 2023 Annual Report Company's complete industrial chain integration to continuously tap the potential and increase benefits to produce polyester bottle chips. At present, its production capacity ranks first in China, with part of PTA production capacity consumed locally, which enhances the competitiveness of the enterprise and improve the economic benefits. The 500,000 tons of differentiated fiber project of Shengyuan Phase II, which mainly produces flame-retardant, functional and dye-free fiber products, is also in progress. 2.

X. Structured Entities Controlled by the Company □Applicable Not applicable XI. Prospect for the Company's Future Development In 2024, the market demand has shown signs of recovery and will further improve in the future, and the national, provincial and municipal levels have introduced relevant policies to support the development of enterprises and stabilize the economy, and we believe that opportunities abound for the development of the Company. Under the leadership of the Board of Directors and the management, we will implement the relevant work in accordance with the established guidelines to ensure the stable release of benefits from existing projects and the smooth implementation of new projects. (I) Business plan 1. Reviewing the situation to draw up a road map for strategic development The year 2024 is the 75th anniversary of the founding of China, and also a key year for the 14th Five-Year Plan to set targets and tasks. It is a year full of challenges, hopes and opportunities for innovation. From the current development situation of the industry, it can be seen that the current economy of China’s petroleum and chemical industry is in a critical period of stabilization and recovery, shift in driving forces and high-quality development to build a solid foundation. 54 / 269 Full Text of 2023 Annual Report The central economic work conference clearly states that it is imperative to deepen the supply-side structural reform and focus on expanding effective demand synergy. Therefore, we should pay close attention to the latest developments of the external situation, keep a close eye on the latest policies issued by the state and local governments and changes in market conditions, draw a road map and issue a mission statement, flexibly adjust production and marketing strategies under the state of normal business operations, and do a good job of timely risk prevention and control so as to seize the trends and opportunities with excellent strategic vision and win the initiative in market competition. 2. Grasping both the internal and the external to ensure sound operation and development Rongsheng’s integrated industrial chain layout has a strong foundation, and the layout in the field of high- end petrochemicals and new materials has been comprehensively carried out. Under the constraints of “dual- control” and “dual-carbon”, accelerating the development of high-end petrochemicals and new chemical materials is a general trend. We will always focus on the core task of enterprise development, coordinate production, operation and project construction, do a good job in internal mechanism control and external risk prevention and control, and actively seize the development opportunities to help the Company achieve high- quality development. At the beginning of the new year, we released Announcement on the Signing of a Memorandum of Understanding with Saudi Arabian Oil Company and Announcement on Investment and Construction of Jintang New Materials Project. The implementation of these major projects requires us to take into account both the internal and the external, and conduct scientific planning. While accelerating the advancement of investment projects, we must always pay attention to the prevention and control of risk so as to have a deep understanding of the situation and take appropriate actions when necessary. 3. Using innovation to drive scientific research and development Innovation is the primary driving force of development. At present, a new round of scientific and technological revolution and industrial transformations are developing rapidly and new technologies, new products and new forms of business are constantly emerging. We have to realize that the future of industrial science and technology innovation is like a running race that waits for no one, which requires us to be ahead of the others and seize the first opportunity, as the first mover is often easier to gain a competitive edge. We will go further to promote the deep integration of industry, academia, research and application, accelerate the R&D and innovation of high-end new materials, focus on the “stranglehold” and sophisticated areas, speed up the adjustment of industrial structure, tackle the problems in green petrochemical technology, promote the construction of digital and intelligent innovation and development system, form new productive forces and build the world’s leading green petrochemical technology innovation platform. 4. Taking concrete actions to cultivate the fertile soil for talents to grow Talents are the most important resources. Since enterprise development depends on talents, we need to find talents, use talents and allocate talents with a higher standpoint and wider vision. The Company always sticks to 55 / 269 Full Text of 2023 Annual Report safeguarding the rights and interests of employees, providing a healthy working environment for employees, and opening up the channels for the growth of talents, so that every employee can become the backbone of the Company’s high-quality development. On the new journey, we will continue to promote the cultivation of various types of talents, firmly take the road of independent training of talents, continue to improve the mechanism, build a good platform and cultivate the fertile soil for the growth of talents, so that the roots of talents can be more developed and one crop after another of talents can thrive, turning a steady stream of talents into the surging momentum for inexhaustible development. (II) Risks the Company may Face 1. Risk from fluctuation of raw material products As a member of the crude oil industrial chain, the main cost of the Company’s products is the cost of upstream raw materials. Therefore, the fluctuation of crude oil prices will result in the price fluctuation of products in the industry chain. The Company’s main products are aromatic hydrocarbons, chemicals and oil products, which are closely related to the national economy and people's livelihood. The industry development is highly correlated with the prosperity of the national economy, and macroeconomic changes will have a certain adverse impact on our performance. The Company’s purchasing and marketing team and production team has rich experience in procurement, trade, hedging, and logistics. With the help of the marketing department, we will focus on market changes, adhere to the combination of strategic procurement and preferential procurement, and effectively reduce procurement costs. We also strengthen sales management and arrange flexible long-term and short-term contracts to reduce the adverse impact of raw material fluctuations. 2. Foreign currency exchange rate fluctuation risk In the future, the market-oriented reform of the exchange rate will become one of the important factors affecting investors’ asset allocation. If the USD further strengthens in the interest rate increase cycle, it may lead to greater pressure on the depreciation of RMB. As the Company pursues international growth, the sharp fluctuation of the currency exchange rate of foreign exchange settlement, which is dominated by the USD, will jeopardize the its daily operations. While controlling financial risks, the Company will continue to optimize the financing structure and the financing scale of USD funds, control the cost within a reasonable range, and then reduce the adverse impact of the exchange rate. 3. Risk of product overcapacity With the expansion of domestic refining and chemical integration capacity and the promotion of the strategy of "reducing oil and increasing chemicals" in recent years, the basic chemical raw materials and general chemical products in the downstream of refining and chemical industry are characterized by certain homogenization. With the support of the Company's complete and refined industrial chain platform, the Company will still be at the left end of the industry cost curve in the future, thus occupying a favorable position in the market competition. On the other hand, many products in the new materials project planned by the 56 / 269 Full Text of 2023 Annual Report Company have less domestic production capacity or even rely entirely on imports, which will bring excess returns to the Company. 4. Risk of project capital expenditure Petrochemical industry is a capital-intensive industry with large investment scale and long construction period. Continued large-scale capital investment will likely increase the level of asset-liability ratio and trigger cash flow risks. Besides, in the context of overcapacity in the industry and sluggish downstream demand, the return on invested capital may also be less than expected. After the second phase of ZPC was put into production, although the Company planned several new materials projects intensively, it has strictly controlled the pace of investment and construction, adjusted the project content in strict accordance with the market situation, maintained a reasonable asset-liability ratio, and actively negotiated cooperation with foreign petrochemical giants such as Saudi Aramco to create a more competitive refining and chemical integration platform.

Audit Report Type of audit opinion Standard unqualified opinion Audit Report Signing Date April 24, 2024 Pan-China Certified Public Accountants (Special General Name of auditor Partnership) Audit Report No. 2024 (4366) Name of certified public accountants Jia Chuan, Xu Haihong Text of Audit Report I. Audit Opinion We have audited the financial statements of Rongsheng Petrochemical Co., Ltd. (the “Company”), which comprise the consolidated and parent company balance sheets as at December 31, 2023, the consolidated and parent company income statements, consolidated and parent company cash flow statements, and consolidated and parent company statements of changes in equity for the year then ended, as well as notes to financial statements. In our opinion, the accompanying financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2023, and its financial performance and its cash flows for the year then ended in accordance with China Accounting Standards for Business Enterprises. II. Basis for Audit Opinion We conducted our audit in accordance with China Standards on Auditing. Our responsibilities under those standards are further described in the Certified Public Accountant’s Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company in accordance with the China Code of Ethics for Certified Public Accountants, and we have fulfilled other ethical responsibilities. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. III. Key Audit Matters Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not express a separate opinion on these matters. (I) Revenue recognition 1. Description of matters Please refer to section III (XXIV) and V (II) 1 of notes to the financial statements for details. The operating income of Rongsheng Petrochemical Company mainly comes from the sales of refinery products, chemical products, PTA, polyester chips, polyester yarns, polyester films, etc. In 2023, the operating revenue amounted to 325,111.61 million yuan. According to the sales contract entered into between the Company and its customers, revenue from sales of goods is recognized when the customer has obtained the control over related goods. As operating revenue is one of the key performance indicators of the Company, there might be inherent risks that the Company’s management (the “Management”) adopts inappropriate revenue recognition to achieve specific goals or expectations, we have identified revenue recognition as a key audit matter. 2. Responsive audit procedures 142 / 269 Full Text of 2023 Annual Report Our main audit procedures for revenue recognition are as follows: (1) We obtained understandings of key internal controls related to revenue recognition, assessed the design of these controls, determined whether they had been executed, and tested the effectiveness of the operation; (2) We checked sales contracts, obtained understandings of main contractual terms or conditions, confirmed the transaction essence of the related businesses in combination with their background, and assessed whether the revenue recognition method was appropriate; (3) We performed analysis procedure on operating revenue and gross margin by month, product, customer, etc., so as to identify whether there are significant or abnormal fluctuations and find out the reason; (4) For revenue from domestic sales, we checked supporting documents related to revenue recognition by sampling method, including sales contracts, orders, sales invoices, outbound delivery orders, logistics records, delivery receipts, etc.; for revenue from overseas sales, we obtained information from Electron Port and checked it with accounting records, and checked supporting documents including sales contracts, bills of clearance, waybills, sales invoices, delivery and shipping records, etc. by sampling method; (5) We performed confirmation procedures on sales amount of major customers by sampling method in combination with confirmation procedure of accounts receivable; (6) We performed cut-off tests to check whether the revenue was recognized in the appropriate period; (7) We obtained sales return records subsequent to the balance sheet date and checked whether there was revenue not eligible for recognition at the balance sheet date; and (8) We checked whether information related to operating revenue had been presented appropriately in the financial statements. (II) Measurement of fixed assets and construction in progress 1. Description of matters Please refer to section III (XVI), III (XVII), III (XVIIII) and V (I) 11 and 12 of notes to the financial statements for details. As of December 31, 2023, the book balance of fixed assets presented in the financial statements of the Company amounted to 219,699.68 million yuan, which mainly refer to machinery used for production of refining- chemical products, etc. and corresponding plants. Such assets are accounted for as fixed assets when they reach the designed usable conditions, with depreciation made using the straight-line method over their estimated useful lives. As of December 31, 2023, the book balance of construction in progress presented in the financial statements of the Company amounted to 41,820.67 million yuan, which mainly refers to 1.40 million tons of ethylene, as well as downstream chemical plant installations, public works and supporting facilities, etc. Such construction in progress is measured at actual cost, which include construction costs, installation costs, borrowing costs eligible for capitalization and other necessary expenditures incurred to bring the construction in progress to its designed usable conditions, including expenditures on engineering design, supervision, cost consultancy, etc. The judgments made by the Management would have an impact on the carrying amount of fixed assets and construction in progress, as well as deprecation policy for fixed assets, which includes: determination of expenditures eligible for capitalization, time point of transferring the construction in progress into fixed assets and starting deprecation, estimation of the economic useful life and the residual value of corresponding fixed assets. As the assessment of carrying amount of fixed assets and construction in progress involves significant judgment of the Management, and may have significant impact on the consolidated financial statements, we have identified measurement and recognition of fixed assets and construction in progress as a key audit matter. 2. Responsive audit procedures Our main audit procedures for measurement of fixed assets and construction in progress are as follows: 143 / 269 Full Text of 2023 Annual Report (1) We obtained understandings of key internal controls related to measurement of fixed assets and construction in progress, assessed the design of these controls, determined whether they had been executed, and tested the effectiveness of the operation; (2) We checked newly increased construction in progress by sampling method, confirmed whether they were eligible for capitalization, spot checked construction and installation costs with significant amount increased in the current period, checked related construction contracts, and cross checked the actual amount paid with invoices and payment vouchers; (3) We obtained loan contracts and reviewed the accuracy and completeness of recognition of capitalized interest in combination with the inputs into construction in progress; (4) We conducted on-site observation on engineering construction to obtain an understanding of and assess the progress of engineering, so as to confirm whether there are significant differences between the observation results and the Company’s accounting records; (5) We confirmed the time point of transferring construction in progress to fixed assets, checked the accuracy of the time point in combination with on-site observation and fixed assets acceptance reports; (6) We assessed the reasonableness of depreciation method of fixed assets to further review the reasonableness of accrued depreciations; and (7) We checked whether information related to fixed assets and construction in progress had been presented appropriately in the financial statements. IV. Other Information Management is responsible for the other information. The other information comprises the information included in the Company’s annual report, but does not include the financial statements and our auditor’s report thereon. Our opinion on the financial statements does not cover the other information and we do not express any form of assurance conclusion thereon. In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of the other information, we are required to report that fact. We have nothing to report in this regard. V. Responsibilities of the Management and Those Charged with Governance for the Financial Statements The Management is responsible for preparing and presenting fairly the financial statements in accordance with China Accounting Standards for Business Enterprises, as well as designing, implementing and maintaining internal control relevant to the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the Management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so. Those charged with governance are responsible for overseeing the Company’s financial reporting process. VI. Certified Public Accountant’s Responsibilities for the Audit of the Financial Statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in 144 / 269 Full Text of 2023 Annual Report accordance with China Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. We exercise professional judgment and maintain professional skepticism throughout the audit performed in accordance with China Standards on Auditing. We also: (I) Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. (II) Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances. (III) Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Management. (IV) Conclude on the appropriateness of the Management’s use of the going concern basis of accounting and based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern. (V) Evaluate the overall presentation, structure and content of the financial statements, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation. (VI) Obtain sufficient and appropriate audit evidence regarding the financial information of the entities or business activities within the Company to express an opinion on the financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain sole responsibility for our audit opinion. We communicate with those charged with governance regarding the planned audit scope, time schedule and significant audit findings, including any deficiencies in internal control of concern that we identify during our audit. We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards. From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Accounting methods for business combinations under the same control and not under the same control 1. Accounting methods for business combinations under the same control The assets and liabilities acquired by the Company in business combination shall be measured according to the book value of the combined party in the consolidated financial statements of the final controlling party on the date of combination. The Company shall adjust the capital reserve according to the difference between the book value share of the owner’s equity of the combined party in the consolidated financial statements of the final controlling party and the book value of the consolidated consideration paid or the total face value of the issued shares; If the capital reserve is not sufficient for offsetting, the adjustment is made to retained earnings. 2. Accounting methods for business combinations not under the common control On the purchase date, the difference between the combined cost and the fair value share of the identifiable net assets of the acquiree obtained in the merger is recognized as goodwill. If the combined cost is less than the fair value share of the identifiable net assets of the acquiree obtained in the combination, first, the fair value of identifiable assets, liabilities and contingent liabilities of the acquiree and the measurement of combined cost are reviewed. If the combined cost is still less than the fair value share of identifiable net assets of the acquiree obtained in the merger after review, the difference is included in the current gain and loss. 7. Judgement criteria for control and compilation method of consolidated financial statements 1. Judgement of control An investor controls an investee if and only if the investor has all the following: (1) power over the investee; (2) exposure, or rights, to variable returns from its involvement with the investee; and (3) the ability to use its power over the investee to affect the amount of the investor’s returns. 2. Compilation method of consolidated financial statements The parent company brings all its controlled subsidiaries into the consolidation scope. The consolidated financial statements are compiled by the parent company according to “CASBE 33 – Consolidated Financial Statements”, based on relevant information and the financial statements of the parent company and its subsidiaries. 8. Classification of joint arrangements and accounting treatment of joint operations 1. Joint arrangements include joint operations and joint ventures. 2. When the Company is a joint operator of a joint operation, it recognizes the following items in relation to its interest in a joint operation: (1) its assets, including its share of any assets held jointly; (2) its liabilities, including its share of any liabilities incurred jointly; (3) its revenue from the sale of its share of the output arising from the joint operation; (4) its share of the revenue from the sale of the assets by the joint operation; and (5) its expenses, including its share of any expenses incurred jointly. 9. Recognition standard for cash and cash equivalents Cash listed in the statement of cash flows refers to cash on hand and deposits that can be used for payment at any time. The term “cash equivalents” refers to short-term and highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value. 10. Foreign currency business and conversion of foreign currency statements 168 / 269 Full Text of 2023 Annual Report 1. Translation of foreign currency business In foreign currency transactions, the spot exchange rate at the transaction date shall be adopted at the initial recognition to convert the foreign currency into the amount of RMB. On the balance sheet date, the monetary items denominated in foreign currencies are translated at the spot exchange rate on the balance sheet date. The exchange differences arising from the exchange rate are included in current gain and loss except for the exchange difference between the principal and interest of foreign currency-specific borrowings related to the acquisition and construction of assets eligible for capitalization. The foreign currency non-monetary items measured at historical cost are still translated at the spot exchange rate at the transaction date, and their RMB amount shall not be changed. Foreign currency non-monetary items measured at fair value are translated at the spot exchange rate at the determination date of fair value, and the exchange differences are included in current gain and loss or other comprehensive income. 2. Translation of foreign currency financial statements Items of assets and liabilities in the balance sheet are translated at the spot exchange rate prevailing on the balance sheet date. Except for the "undistributed profit" item, other items of owner’s equity are translated at the spot exchange rate at the transaction date. Income and expense items in the income statement are translated at the approximate spot exchange rate at the transaction date. The converted difference in foreign currency financial statements arising from the above translations is included in other comprehensive income. 11. Financial instruments 1. Classification of financial assets and financial liabilities At initial recognition, financial assets are classified into the following three categories: (1) financial assets at amortized cost; (2) financial assets at fair value through other comprehensive income; and (3) financial assets at fair value through gain and loss. At initial recognition, financial liabilities are classified into four categories: (1) financial liabilities at fair value through gain and loss; (2) financial liabilities that are formed since the transfer of financial assets do not comply with the conditions for derecognition or continue to involve in the financial assets to be transferred; (3) financial guarantee contracts not falling under the above (1) or (2), and loan commitments not falling under the above (1) and lending at a rate lower than the market interest rate; (4) financial liabilities at amortized cost. 2. Recognition basis, measurement methods and derecognition conditions for financial assets and financial liabilities (1) Recognition basis and initial measurement methods for financial assets and financial liabilities A financial asset or a financial liability shall be recognized when the Company becomes a party to a financial instrument contract. A financial asset or financial liability shall be measured at fair value at the initial recognition. For financial assets or financial liabilities at fair value through gain and loss, the transaction expenses thereof shall be directly recorded in current gain and loss. For other categories of financial assets or financial liabilities, the related transaction expenses are included in the initial recognition amount. However, if the accounts receivable initially recognized by the Company do not contain significant financing components or the Company does not consider the financing components in contracts less than one year, the initial recognition shall be carried out according to transaction price as defined in the Accounting Standards for Business Enterprises No. 14—Revenue. (2) Subsequent measurement method for financial assets 1) Financial assets measured at amortized cost They are subsequently measured at amortized cost by adopting the effective interest method. Gains or losses arising from financial assets measured at amortized cost and not part of any hedging relationship are included in 169 / 269 Full Text of 2023 Annual Report current gain and loss upon derecognition, reclassification, amortization under the effective interest method or recognition of impairment. 2) Debt instrument investments at fair value through other comprehensive income They are subsequently measured at fair value. Interest, impairment losses or gains and exchange gains and losses calculated by the effective interest method are included in current gain and loss, and other gains or losses are included in other comprehensive income. Upon derecognition, the accumulated gain or loss previously included in other comprehensive incomes is transferred from other comprehensive incomes and included in the current gain and loss. 3) Equity instrument investments at fair value through other comprehensive income They are subsequently measured at fair value. Dividends obtained (except those falling under the recovery of investment costs) are included in current gain and loss, and other gains or losses are included in other comprehensive income. Upon derecognition, the accumulated gain or loss previously included in other comprehensive incomes is transferred out from other comprehensive incomes and included in retained earnings. 4) Financial assets at fair value through gain and loss They are subsequently measured at fair value, and the resulting gains or losses (including interest and dividend income) are included in current gain and loss, unless the financial asset is part of the hedging relationship. (3) Subsequent measurement method for financial liabilities 1) Financial liabilities at fair value through gain and loss Such financial liabilities comprise trading financial liabilities (including derivatives of financial liabilities) and those specified as financial liabilities at fair value through gain and loss. Such financial liabilities are subsequently measured at fair value. Change in fair value of financial liability designated to be measured at fair value through gain and loss due to change in the Company’s own credit risk is included in other comprehensive income, unless the treatment will cause or expand the accounting mismatch in gain and loss. Other gains or losses arising from such financial liabilities (including interest expenses, except changes in fair value caused by changes in the own credit risk) are included in current gain and loss, unless the financial liabilities are part of the hedging relationship. Upon derecognition, the accumulated gain or loss previously included in other comprehensive incomes is transferred out from other comprehensive incomes and included in retained earnings. 2) Financial liabilities that are formed since the transfer of financial asset does not comply with the conditions for derecognition or continue to involve in the financial assets to be transferred They are measured pursuant to relevant provisions under Accounting Standards for Business Enterprises No. 23—Transfer of Financial Assets. 3) Financial guarantee contracts not falling under the above 1) or 2), and loan commitments not falling under the above 1) and to lend at a rate lower than the market interest rate A subsequent measurement shall be made after they are initially recognized according to the higher one of the following: ① the amount of loss reserve determined in accordance with the impairment provisions of financial instruments; ② the remaining amount after the determined accumulative amortization amount is deducted from the initially recognized amount in accordance with relevant provisions of the Accounting Standards for Business Enterprises No.14—Revenue. 4) Financial liabilities at amortized cost They are measured at amortized cost under the effective interest method. Gains or losses arising from financial liabilities measured at amortized cost and not part of any hedging relationship are included in current gain and loss when derecognized and amortized under the effective interest method. (4) Derecognition of financial assets and financial liabilities 170 / 269 Full Text of 2023 Annual Report 1) The Company will derecognize the financial assets when one of the following conditions are met: ① The contractual rights to the cash flows from the financial asset expire; ② The transfer of such financial assets has been completed and is in line with the provisions on derecognition of a financial asset under the Accounting Standards for Business Enterprises No. 23—Transfer of Financial Assets. 2) When the current obligations of financial liabilities (or part thereof) have been discharged, the recognition of the financial liabilities (or part thereof) shall be terminated accordingly. 3. Recognition basis and measurement method for transfer of financial assets Where the Company transfers almost all risks and returns related to the ownership of the financial assets transferred, these financial assets will be derecognized, and the rights and obligations that occurred or were retained during the transfer are separately recognized as assets or liabilities. Where almost all risks and rewards on the ownership of financial assets are retained, the transferred financial assets shall continue to be recognized. Where the Company has neither transferred nor retained any risk and reward relating to the ownership of the financial assets, it shall be disposed of in the following conditions: (1) where the control over the financial asset is not retained, the recognition of the financial asset shall be terminated, and the rights and obligations arising or retained in the transfer shall be separately recognized as assets or liabilities; 2) where the control over the financial asset is retained, the relevant financial asset shall be recognized according to the degree of continued involvement in the transferred financial asset, and the relevant liabilities shall be recognized accordingly. When the overall transfer of financial assets meets the conditions for derecognition, the difference between the following two amounts shall be included in the current gain and loss: (1) the book value of the transferred financial assets on the date of derecognition; (2) the sum of the consideration received from the transfer of financial assets and the amount of the derecognized part in a cumulative amount of change in fair value which is originally included in other comprehensive income (the financial assets involved in the transfer are debt instrument investments at fair value through other comprehensive income). A part of financial assets is transferred, and if the transferred part meets the conditions for derecognition entirely, the book value of the whole financial asset before transfer shall be allocated between the derecognized part and the continued recognition part according to their relative fair values on the transfer date, and the difference between the following two amounts shall be included in current gain and loss: (1) the book value of the derecognized part; (2) the sum of the consideration of the derecognized part and the amount of the corresponding derecognized part in the accumulated amount of changes in fair value originally directly included in other comprehensive income (the financial assets involved in the transfer are debt instrument investments at fair value through other comprehensive income). 4. Methods for determination of the fair value of financial assets and financial liabilities When determining the fair value of related financial assets and financial liabilities, the Company adopts the valuation technique applicable in the prevailing circumstance and supported by sufficient available data and other information. The Company classifies the input values used by the valuation technique as the following tiers and uses them in turns: (1) Tier 1 input value refers to the unadjusted quotations of the same assets or liabilities in an active market which can be obtained on the measurement date; (2) Tier 2 input value refers to them directly or indirectly observable input value of relevant assets or liabilities apart from Tier 1 input value, including: quotations of similar assets or liabilities on an active market; quotations of identical or similar assets or liabilities in markets that are not active; observable input values other than quotations, such as interest rates and yield curves that are observable during normal quotation intervals; input values for market validation, etc.; 171 / 269 Full Text of 2023 Annual Report (3) Tier 3 input value refers to the unobservable input value of relevant assets or liabilities, including the volatility of interest rate and stock that cannot be directly observed or cannot be verified by observable market data, the future cash flows of the disposal obligations assumed in the business combination, financial forecasts made using its own data, etc. 5. Impairment of financial instruments On the basis of expected credit loss, for financial assets at amortized cost, debt instrument investments at fair value through other comprehensive income, contract assets, lease receivables, loan commitments classified as financial liabilities at fair value through gain and loss, financial guarantee contracts that do not belong to financial liabilities at fair value through gain and loss or financial liabilities formed by the transfer of financial assets that do not meet the conditions for derecognition or continue to be involved in the transferred financial assets shall be impaired and loss reserve shall be recognized. Expected credit loss refers to the weighted average of credit losses of financial instruments weighted by the risk of default. Credit loss refers to the difference between all contract cash flow receivables according to the contract, and all cash flows expected to be collected, that is, the present value of all cash shortages. The financial assets purchased or generated by the Company that have suffered credit impairment are discounted according to the credit-adjusted effective interest rate of the financial assets. For the purchased or originated financial assets with credit impairment, the Company only recognizes the cumulative change of expected credit loss in the whole existence period after initial recognition as the loss reserve on the balance sheet date. For leases receivable, and accounts receivable and contract assets resulting from transactions regulated in “CASBE 14 – Revenues”, the Company chooses simplified approach to measure the loss allowance at an amount equal to lifetime expected credit losses. For financial assets other than the above measurement methods, the Company assesses whether its credit risk has increased significantly since initial recognition on each balance sheet date. If the credit risk has increased significantly since the initial recognition, the Company shall measure the loss reserve according to the amount of expected credit loss during the whole existence period. If the credit risk has not increased significantly since the initial recognition, the Company shall measure the loss reserve according to the amount of expected credit loss of the financial instrument in the next 12 months. The Company uses available reasonable and credible information, including forward-looking information, to determine whether the credit risk of financial instruments has increased significantly since the initial recognition by comparing the default risk of financial instruments on the balance sheet date with the default risk on the initial recognition date. On the balance sheet date, if the Company judges that the financial instrument only has low credit risk, it is assumed that the credit risk of the financial instrument has not increased significantly since the initial recognition. The Company evaluates the expected credit risk and measures the expected credit loss on the basis of a single financial instrument or combination of financial instruments. When based on the portfolio of financial instruments, the Company divides the financial instruments into different portfolios according to the common risk characteristics. The Company re-measures the expected credit loss on each balance sheet date, and the resulting increase or reversal of the loss reserve is included in the current gain and loss as impairment loss or profit. For financial assets at amortized cost, the loss provision is offset against the book value of the financial asset as given in the balance sheet; For debt investment measured at fair value through other comprehensive income, the loss allowances are recognized in other comprehensive income by the Company instead of offsetting the book value of the financial assets. 172 / 269 Full Text of 2023 Annual Report 6. Offset of financial assets and financial liabilities Financial assets and financial liabilities are listed separately on the balance sheet and can not offset each other. However, if the following conditions are met at the same time, the net amount after mutual offset shall be listed in the balance sheet: (1) the Company has the legal right to set off the recognized amount, and such legal right is currently enforceable; (2) the Company intends either to settle on a net basis, or to realize the financial assets and pay off the financial liabilities simultaneously. For the transfer of financial assets not in line with the conditions for derecognition, the Company does not offset the transferred financial assets and liabilities. 12. Contract assets The Company presents contract assets or liabilities in the balance sheet based on the relation between performance obligation and customer payment. Contract assets and contract liabilities under the same contract shall offset each other and be presented on a net basis. The Company presents an unconditional right to consideration (i.e., only the passage of time is required before the consideration is due) as a receivable, and presents a right to consideration in exchange for goods that it has transferred to a customer (which is conditional on something other than the passage of time) as a contract asset. 1. Receivables and contract assets subject to expected credit losses based on a combination of credit risk characteristics Basis for determining Category of combination Method for measuring expected credit loss portfolios Banker’s acceptance receivables With reference to historical credit loss experience and in combination with the current situation and the forecast of future economic conditions, the Type of notes Commercial acceptance bill receivables expected credit loss is calculated through default risk exposure and the expected credit loss rate in the whole duration With reference to historical credit loss experience and in combination with the current situation and the forecast of future economic conditions, the Accounts receivable - aging portfolio Aging comparison table between the aging of accounts receivable and the expected credit loss rate is compiled to calculate the expected credit loss Accounts receivable - trade accounts With reference to historical credit loss experience Nature of account portfolio of overseas subsidiaries and in combination with the current situation and the forecast of future economic conditions, the Accounts receivable - Related party expected credit loss is calculated through default Related parties within the dealings portfolio within the scope of risk exposure and the expected credit loss rate in the scope of consolidation [note] consolidation whole duration Other receivables - Related party dealings Related parties within the portfolio within the scope of consolidation scope of consolidation [note] Other receivables - Loan margin portfolio Other receivables - government receivables portfolio With reference to historical credit loss experience and in combination with the current situation and Other receivables - futures margin portfolio the forecast of future economic conditions, the expected credit loss is calculated through default Other receivables - paper goods transaction Nature of account risk exposure and the expected credit loss rate in the settlement portfolio next 12 months or the whole duration.

Recognition criteria for receivables and contract assets with expected credit losses measured on an individual basis For receivables and contract assets whose credit risk is significantly different from that of portfolios, the Company accrues expected credit losses on an individual basis. 13. Inventories 1. Classification of inventories Inventory includes finished products or commodities held for sale in daily activities, products in the process of production, materials and supplies consumed in the process of production or providing labor services. 2. Valuation method for delivered inventories Inventories delivered shall be weighted average at the end of each month. 3. Inventory system of inventories The perpetual inventory system is adopted for inventories. 4. Amortization method for low-value consumables and packaging materials (1) Low-value consumables Low-value consumables are amortized using the one-off amortization method. (2) Packages Packages are amortized with one-off method. 5. Recognition criteria and accrual method of provision for inventory write-down At the balance sheet date, inventories are measured at the lower of cost and net realizable value; provisions for inventory write-down are made on the excess of its cost over the net realizable value. The net realizable value of inventory directly used for sale will be determined by the amount of the estimated selling price of the inventory minus the estimated sales expenses and related taxes. For inventories that need to be processed, the net realizable value shall be determined in the normal production and operation process by subtracting the estimated selling price of finished products produced from the estimated cost to be incurred when completion, the estimated sales expenses and relevant taxes and fees. On the balance sheet date, if a part of the same inventory has a contract price agreement and other parts do not have a contract price, the net realizable value shall be determined respectively, and the corresponding cost shall be compared to determine the accrual or reversal amount of inventory depreciation reserve respectively. 14. Long-term equity investment 1. Judgment of joint control and significant influence 174 / 269 Full Text of 2023 Annual Report Joint control refers to the shared control over a certain arrangement according to the relevant agreement, and the activities under such arrangement are subject to approval by the parties sharing the control power. Significant influence refers to that one party has the power to participate in the decision-making of financial and operating policies of the investee but is unable to control or jointly control these policies with other parties. 2. Determination of investment cost (1) For business combination under the same control, where the combining party uses cash payment, transfer of non-cash assets, assumption of debts or issuing of equity securities as combination consideration, the share of owner’s equity of the combined party acquired in the book value of total owner’s equity in consolidated financial statements of the ultimate controller on the combination date shall be identified as the initial investment cost of long-term equity investment. The difference between the initial investment cost of long-term equity investment and the book value of the combination consideration paid or the par value of the issued shares is adjusted against the capital reserve. If the capital reserve is not sufficient for offsetting, the adjustment is made to retained earnings. For the long-term equity investments formed through business combination under the same control] and implemented through multiple transactions step by step by the Company, it is a must to judge whether they are “package deals”. If they are package deals, each deal is regarded as a deal to obtain control right for accounting treatment. If it is not a package deal, on the date of combination, the share of the book value of net assets of the combined party that should be enjoyed after combination in the consolidated financial statements of the ultimate controller, is recognized as an initial investment cost. The difference between the initial investment cost of long- term equity investment on the date of combination and the sum of the book value of long-term equity investment before the combination is realized and the book value of consideration additionally paid to further acquire shares on the date of combination is adjusted against the capital reserve. If the capital reserve is not sufficient for offsetting, the adjustment is made to retained earnings. (2) As for business combinations not under the same control, the fair value of the combination consideration paid on the combination date is recorded as the initial investment cost of long-term equity investment. For the long-term equity investments formed through business combination not under the same control and implemented through multiple transactions step by step by the Company, the accounting treatment is different in unconsolidated financial statements and consolidated financial statements: 1) In individual financial statements, the initial investment cost of long-term equity investment accounted using the cost method is measured at the sum of the book value of equity investment originally held and investment cost additionally paid. 2) In consolidated financial statements, it is a must to judge whether they are “package deals”. If they are package deals, each deal is regarded as a deal to obtain control right for accounting treatment. Suppose these transactions are not "package deals", the equities of the acquiree held before the purchase date shall be re- measured at fair value at the purchase date. The difference between the fair value and its book value shall be recognized as current investment income. In case the equity of the acquiree held before the purchase date involves other comprehensive income under the equity method, relevant other comprehensive income shall be transferred to the current return on the purchase date, except for other comprehensive income resulting from the re- measurement of the investee’s net defined benefit plan liabilities or changes in net assets. (3) Except for the formation of business combination: As for those obtained by cash payment, the actually paid purchase price is taken as the initial investment cost; the long-term equity investment formed by issuing equity securities, the fair value of issuing equity securities is taken as the initial investment costs. If acquired through debt restructuring, its initial investment cost shall be determined in accordance with the Accounting Standards for Business Enterprises No. 12—Debt Restructuring; in the case of non-monetary asset exchange, the initial investment cost shall be determined in accordance with the Accounting Standards for Business Enterprises No. 7—Exchange of Non-monetary Assets. 175 / 269 Full Text of 2023 Annual Report 3. Methods for subsequent measurement and gain and loss recognition The long-term equity investment in the invested entity under its control will be accounted for through the cost method; long-term equity investment in associated enterprises and joint ventures is accounted for under the equity method. 4. Treatment methods for investments in subsidiaries through multiple deals step by step until control losing (1) Judgment principle for whether a "package deal" or not If the equity investment in the subsidiary is disposed of step by step through multiple transactions until it loses control, the Company will judge whether the step-by-step transaction is a "package deal" by combining the terms of the transaction agreement, the disposal consideration obtained separately, the object of equity sale, the disposal method and the disposal time in each step of the step-by-step transactions. The terms, conditions and economic impact of each transaction meet one or more of the following conditions, which usually indicates that multiple transactions are "package deals": 1) These transactions were concluded at the same time or under the consideration of mutual impact; 2) These transactions as a whole can achieve a complete business result; 3) The occurrence of a transaction depends on the occurrence of at least one other transaction; 4) A transaction is uneconomical when viewed alone, but it is economical when considered together with other transactions. (2) Accounting treatment for non-"package deals" 1) Individual financial statements For disposal of equity, the difference between book value and the actual price of the acquisition shall be recorded into current gain and loss. For the remaining equity, if the investor still has significant influence over the investee or imposes joint control with other parties, it is accounted for by the equity method; In case of failure to control, jointly control or significantly influence the investee, it shall be calculated in accordance with the provisions of the Accounting Standards for Business Enterprises No. 22—Recognition and Measurement of Financial Instruments. 2) Consolidated financial statements Before losing control, the capital reserves (capital premium) are adjusted at the difference between the disposal cost and the share in net assets of subsidiaries calculated continuously from the acquisition date or combination date corresponding to the disposal of long-term equity investment; if the capital premium is not sufficient to be offset, retained earnings are offset. When losing control over a former subsidiary, the remaining equity is re-measured at the fair value on the date of control loss. The balance of the sum of the consideration received through the disposal of equity and the fair value of the remaining equity after deducting the entitled share of net assets continuously calculated at the original shareholding ratio from the purchase date or the date of combination in the subsidiary is recognized in the investment income for the period during which the control is lost, and is written off against goodwill. Other comprehensive income related to equity investment in the former subsidiary is transferred into return on investment for the period during which the control is lost. (3) Accounting treatment for "package deals" 1) Individual financial statements Each deal is considered as a deal for the disposal of the subsidiary and losing control of accounting treatment. However, the difference between the disposal cost of each deal before losing the control and the book value of long-term equity investment corresponding to the disposal investment is recognized as other comprehensive income in individual financial statements, and when the control is lost, transferred together into gain and loss for the period during which the control is lost. 176 / 269 Full Text of 2023 Annual Report 2) Consolidated financial statements Each deal is considered as a deal for the disposal of the subsidiary and losing control of accounting treatment. However, the difference between the disposal cost of each deal before losing the control and the entitled share of net assets of the subsidiary corresponding to the disposal investment is recognized as other comprehensive income in consolidated financial statements, and when the control is lost, transferred together into gain and loss for the period during which the control is lost. 15. Investment properties Measurement model of investment properties Measurement by the cost method Depreciation or amortization methods 1. Investment properties of the Company include the land use rights leased and held for sale after appreciation, and leased buildings. 2. Investment properties are initially measured by cost and subsequently measured by the cost model, with its depreciation or amortization conducted by the same methods for fixed assets and intangible assets. 16. Fixed assets (1) Recognition conditions Fixed assets refer to tangible assets held for production, service, lease or operation with a service life of more than one accounting year. Fixed assets can be recognized only when related economic benefits are very likely to flow into the Company, and their costs can be measured reliably. (2) Depreciation method Depreciable life Annual depreciation Category Depreciation method Residual value rate (years) rate Straight-line Housing and buildings 5-30 5 or 10 19.00-3.00 depreciation method Machinery and Straight-line 10-15 5 or 10 9.50-6.00 equipment depreciation method Transportation Straight-line 4-5 5 or 10 23.75-18.00 facilities depreciation method Straight-line Other equipment 3-10 5 or 10 31.67-9.00 depreciation method 17. Construction in progress 1. Construction in progress is able to be recognized only when related economic benefits are very likely to flow into the Company, and its costs can be measured reliably. Construction in progress is measured at the actual cost incurred before such asset is ready for the intended use. 2. Construction in progress is carried forward to fixed assets based on actual costs of the project when it is ready for its intended use. As for construction in progress which is ready for the intended use but has not gone through the formalities of final accounts of completion, it shall be transferred into fixed assets at the estimated 177 / 269 Full Text of 2023 Annual Report value. Upon the final accounts of completion, the previous tentatively estimated value other than accrued depreciation shall be adjusted based on actual costs. Categories Standards and time point of transferring construction in progress to fixed assets When the main project and supporting projects have been substantially completed and reached the intended Buildings and design requirements, and acceptance has been completed by survey, design, construction, supervision and other structures units. Machinery When the design requirements or standards specified in the contract are met after installation and commissioning 18. Borrowing costs 1. Recognition principle of the capitalization of borrowing costs Where the borrowing costs incurred to the Company can be directly attributable to the acquisition and construction or production of a qualifying asset for capitalization, it shall be capitalized and recognized as costs of relevant assets; Other borrowing costs shall be recognized as an expense when they are incurred and included in current gain and loss. 2. Capitalization period of borrowing costs (1) Capitalization begins when the borrowing cost meets the following conditions: 1) asset expenditure has been incurred; 2) the borrowing costs have been incurred; 3) the acquisition, construction or production activities necessary to bring the asset to its intended use or sales have been initiated. (2) Where the acquisition and construction or production process of assets eligible for capitalization are interrupted abnormally and the interruption period lasts for more than 3 months, the capitalization of the borrowing costs shall be suspended. The borrowing costs incurred during such period shall be recognized as expenses of the current period until the asset’s acquisition and construction or production activity restarts. (3) When the assets acquired, constructed or produced qualified for capitalization conditions are ready for intended use or sales, the capitalization of the borrowing costs shall be ceased. 3. Capitalization rate and amount of borrowing costs In case of special borrowing for the acquisition & construction or production of assets eligible for capitalization conditions, interest income to be capitalized shall be recognized after deducting the bank interests for the unused portion or the investment income for short-term investment from the interest costs (including recognized depreciation or amortization of premium under effective interest method) actually occurred in the current period of specific borrowing. Where a general borrowing is used for the acquisition, construction, or production of assets eligible for capitalization, it shall determine the capitalization amount of interests on the general borrowing by multiplying the weighted average asset expenses of the part of the accumulative asset expenses minus the special borrowings by the capitalization rate of the general borrowings used. 19. Intangible assets (1) Service life and its determination basis, estimation, amortization method or review procedure 1. Intangible assets include land use rights, patent rights and non-patented technology and so on, which are initially measured according to cost. 2. Any intangible asset with a limited service life shall be amortized in a systematic and rational manner based on the expected realization method of economic benefits related to it within its service life; where the expected realization method cannot be confirmed reliably, the straight-line method shall be adopted. Details are as follows: 178 / 269 Full Text of 2023 Annual Report Items Useful life and determination basis Amortization method Land-use right 15-50 years, useful life registered on the land use certificate Straight-line method Proprietary technology 6-10 years, estimated economic useful life Straight-line method Management software 5-10 years, estimated economic useful life Straight-line method Pollution discharge 5-20 years, useful life registered on the certificate of titles Straight-line method right Sea area use right 1-50 years, useful life registered on the certificate of titles Straight-line method (2) Collection scope of R&D expenditure and related accounting treatment methods (1) Personnel costs Personnel costs include wages and salaries, basic endowment insurance premiums, basic medical insurance premiums, unemployment insurance premiums, occupational injuries premiums, maternity premiums and housing provident funds for the Company’s R&D personnel, as well as labor costs for external R&D personnel. If R&D personnel serve for multiple R&D projects at the same time, personnel costs are recognized based on their working hour records provided by the Company’s administrative department, and proportionately allocated among different R&D projects. If personnel directly engaged in R&D activities and external R&D personnel are engaged in non-R&D activities at the same time, the Company, based on their working hour records at different positions, allocates personnel costs actually incurred between R&D expenses and production and operating expenses using reasonable methods such as the ratio of actual working hours. (2) Direct input costs Direct input costs refer to relevant expenses actually incurred by the Company for R&D activities, which include: 1) materials, fuel and power costs directly consumed by R&D activities; 2) development and manufacturing costs of molds and craft equipment used for intermediate tests and trial production, acquisition costs of samples, prototypes and general testing methods that do not constitute fixed assets, and inspection costs of trial production; and 3) operation and maintenance, adjustment, inspection, testing and repairing costs of instruments and equipment used for R&D activities. (3) Depreciation costs Depreciation costs refer to the depreciation of instruments, equipment and in-use buildings used for R&D activities. For instruments, equipment and in-use buildings both used for R&D activities and non-R&D activities, necessary records shall be kept on their usage, and depreciation actually incurred is allocated between R&D expenses and production and operating expenses in a reasonable manner based on the actual working hours, the usable area, etc. (4) Amortization costs of intangible assets Amortization costs of intangible assets refer to the amortization of software, intellectual property, and non- patented technology (proprietary technology, licenses, design and calculation methods, etc.) used for R&D activities. (5) Design expenses Design expenses refer to expenses incurred for the conception, development and manufacturing of new products and techniques, design of processes, technical specifications, process specification formulation, operational characteristics, etc., including expenses incurred for creative design activities to obtain innovative, creative and breakthrough products. 179 / 269 Full Text of 2023 Annual Report (6) Equipment commissioning expenses Equipment commissioning expenses refer to expenses incurred for R&D activities during tooling preparation, including expenses incurred for activities such as development of special and specialized production machines, changes in production and quality control procedures, development of new methods and standards, etc. Expenses incurred for routine tooling preparation and industrial engineering for the purpose of large- scale/mass and commercial production are not included in the permitted scope. (7) R&D outsourcing expenses R&D outsourcing expenses refer to expenses incurred for R&D activities outsourced to other domestic or foreign organizations or individuals (outcomes of R&D activities are owned by the Company and closely related to the Company’s main business operations). (8) Other expenses Other expenses refer to expenses other than those mentioned above that are directly related to R&D activities, including technical books and materials fees, data translation fees, expert consultation fees, high-tech R&D insurance premiums, R&D outcomes search, demonstration, evaluation, appraisal and acceptance fees, intellectual property application, registration and agency fees, conference fees, business travelling fees, communication fees, etc. The expenditure in the research stage of internal R&D projects is included in the current gain and loss. The expenditures incurred during the development of an internal R&D project shall be recognized as intangible assets if they simultaneously meet the following conditions: (1) It is technically feasible to complete the intangible assets so that they can be used or sold; (2) it is intended to finish and use or sell the intangible assets; (3) the ways for intangible assets to generate economic benefits shall be proven useful, including the way to prove that there is a potential market for the products manufactured with the intangible assets or there is a potential market for the intangible assets or the intangible assets will be used internally; (4) enough technical and financial resources and other resources are available to support the development of such intangible assets, and the Company is able to use or sell such intangible assets; (5) the expenses incurred from developing the intangible asset can be reliably measured. 20. Impairment of long-term assets Long-term assets such as long-term equity investment, investment properties measured by the cost model, fixed assets, construction in progress, right-of-use assets and intangible assets with limited service lives shall be evaluated for their recoverable amount in case of any sign of impairment at the balance sheet date. For goodwill formed by business combination and intangible assets with uncertain service life, an impairment test should be carried out every year regardless of whether there is a sign of impairment. Goodwill impairment testing must be done in combination with the asset group or asset group portfolio to which it is linked. Where the recoverable amount of asset is lower than its book value, the Company shall recognize the provision for asset impairment based on the difference and recognize such loss into the current gains and losses. 21. Long-term deferred expenses Long-term deferred expenses refer to all expenses that have been paid and have an amortization period of more than one year (excluding one year). Long-term deferred expenses are recorded at the actual incurred amount and amortized on an average basis by stages over the beneficial period or prescribed period. In case that long-term deferred expense items cannot benefit the future accounting periods, the amortized value of such unamortized items shall be fully transferred into the current gain and loss. 180 / 269 Full Text of 2023 Annual Report 22. Contract liabilities The Company presents contract assets or liabilities in the balance sheet based on the relation between performance obligation and customer payment. The Company will record the net amount of contract assets and contract liabilities under the same contract after they are set off against each other. The Company presents the obligation to transfer goods to the customer for considerations received or receivable from the customer as a contract liability. 23. Employee remuneration Employee remuneration includes short-term remuneration, post-employment benefits, dismissal benefits and other long-term employee benefits. (1) Accounting treatment method for short-term remuneration The actual short-term remuneration in the accounting period when employees offer services for the Company will be recognized as liabilities and included in current gain and loss or relevant asset cost. (2) Accounting treatment method of post-employment benefits Post-employment benefits are divided into defined contribution plans and defined benefit plans. (1) During the accounting period when an employee provides services to the Company, the amount to be deposited according to the defined contribution plan shall be recognized as the liability and recorded into the current gain and loss or the cost of the relevant assets. (2) The accounting treatment for a defined benefit plan generally includes the following steps: 1) In accordance with the projected unit credit method, demographic and financial variables are estimated using unbiased and consistent actuarial assumptions, the obligations arising from the defined benefit plan are measured, and the period for the relevant obligation is determined. In the meantime, the obligations arising from the defined benefit plan are discounted to determine the present value and current cost of service of the defined benefit plan. 2) Where the defined benefit plan involves any assets, the deficit or surplus resulting from the present value of obligations in the defined benefit plan minus the fair value of assets shall be recognized as net liabilities or net assets of the defined benefit plan. Where the defined benefit plan has any surplus, the Company will measure the net assets of the defined benefit plan based on the surplus or asset limit of the defined benefit plan (whichever is the lower); 3) At the end of the period, the Company shall recognize the cost of employee remuneration as cost of service, the net interest of net liabilities or net assets of the defined benefit plan and changes arising from the re- measurement of net liabilities or net assets of the defined benefit plan, in which the cost of service and net interest of net liabilities or net assets of the defined benefit plan are recorded in the current gain and loss or relevant asset cost, changes arising from the re-measurement of net liabilities or net assets of the defined benefit plan are recorded in other comprehensive incomes and is not allowed to be carried back to gains or losses during the subsequent accounting period, but the amounts recognized in other comprehensive incomes can be transferred within the equity scope. 181 / 269 Full Text of 2023 Annual Report (3) Accounting treatment method for dismissal benefits Where dismissal benefits are provided to employees, liabilities in employee remuneration are recognized and included in the current gain and loss when: (1) the Company is not in a position to unilaterally withdraw dismissal benefits provided under termination plans or layoff proposals; (2) when the Company recognizes the costs or expenses related to restructuring involving the payment of dismissal benefits. (4) Accounting treatment method for other long-term employee benefits Where the Company provides other long-term employee benefits for its employees and the employee reaches the conditions of the defined benefit plan, accounting treatment shall be adopted based on relevant provisions of the defined benefit plan. For long-term employee benefits other than the aforesaid ones, the accounting treatment should be conducted in accordance with relevant provisions of the defined benefit plan. In order to simplify relevant accounting treatments, the employee remuneration cost resulting from other long-term employee benefits shall be recognized as cost of service, the total net amount of component items, including net interest of net liabilities or net asset of other long-term employee benefits, as well as changes arising from re-measurement of net liabilities or net asset of other long-term employee benefits and so on, is recorded in current gain and loss or relevant asset cost. 24. Provisions 1. Provisions are recognized when fulfilling the present obligations arising from contingencies such as providing guarantee for other parties, litigation, products quality guarantee, onerous contract, etc., may cause the outflow of the economic benefit and such obligations can be reliably measured. 2. The initial measurement of provisions is based on the best estimated expenditures required in fulfilling the present obligations, and its carrying amount is reviewed at the balance sheet date. 25. Revenue Disclosure of accounting policies adopted for revenue recognition and measurement according to business types 1. Revenue recognition principle The Company assesses the contract from the commencement date of the contract and recognizes each individual performance obligation included by the contract, and determines whether each individual performance obligation will be fulfilled during a certain period or at a certain time point. It will constitute performance of the obligation in a certain period of time if any of the following conditions are met; otherwise it will constitute performance of obligation at a certain time point: (1) the customer obtains and consumes economic benefits arising from contract performance by the Company; (2) the customer can control goods in progress during the process of contract performance by the Company; (3) goods arising from contract performance by the Company have irreplaceable purposes, and the Company is entitled to receive payment for accumulatively completed performance proportion to date throughout the contract term. If the performance obligations are performed within the specified period, the Company will recognize the income within this period in accordance with the progress of the contract’s performance. If the performance progress cannot be determined reasonably and the costs incurred are expected to be compensated, the income will be recognized according to the costs incurred until the performance progress is determined reasonably. If the performance obligations are performed at a time point, the Company will recognize the income at the time when the customer obtains control power over goods or services. When judging whether the customer has already 182 / 269 Full Text of 2023 Annual Report obtained the right of control over goods, the Company shall consider the following items: (1) the Company has the right to receive payment currently; namely, the customer assumes the obligation of making payment currently in regards to the goods; 2) the Company has already transferred the legal ownership of the goods to the customer; namely, the customer has already obtained the legal ownership of such goods; 3) the Company has already transferred the material object of the goods to the customer, namely the customer has already obtained such goods in the material object; 4) the Company has already transferred the significant risk and consideration of the property in the goods to the customer, namely, the customer has already obtained the significant risk and consideration of the property in the goods; (5) the customer has accepted such goods; (6) other signs that indicate the customer has already obtained the control over goods. 2. Revenue measurement principles (1) The income shall be measured by the Company according to the transaction price apportioned to each single performance obligation. Transaction price refers to the amount of consideration the Company expects to receive for the transfer of goods or services to the customer, but it does not include payments received on behalf of the third party or funds to be returned to the customer. (2) In case of variable consideration in contract, the Company will determine the best estimate of variable consideration in line with the expected or most possible amount, but the transaction price that contains variable consideration will not exceed the amount of accumulated recognized income that is least likely to be reversed when relevant uncertainties are removed. (3) If there is significant financing in the contract, the Company shall determine the transaction price according to the amount payable in cash when the client obtains control of the goods or services. The difference between the transaction price and contract consideration is amortized by the effective interest method during the term of the contract. On the contract commencement date, if the Company estimates that the time between the customer’s acquisition of control over goods or services and the payment of the price by the customer will not exceed one year, the significant financing in the contract shall not be considered. (4) If there are two or more performance obligations in the contract, at the beginning of the contract, the Company shall allocate the transaction price to each separate performance obligation according to the relative proportion of the stand-alone selling price of the goods promised by each performance obligation. 3. Specific methods for revenue recognition The Company mainly sells oil refining products, chemical products, PTA, polyester chip, polyester yarn and film, and so forth, fulfilling its performance obligation at a certain time point. Proceeds from domestic sales are recognized when the Company has delivered the products to the buyer, the amount of product sales revenue has been determined, the payment for goods has been recovered, or the collection voucher has been obtained, and the relevant economic benefits are likely to flow in. Proceeds from overseas market sales are recognized when the Company has declared the products at the customs and obtained the bill of lading according to the contract, the amount of product sales revenue has been determined, the payment for goods has been recovered, or the collection voucher has been obtained, and the relevant economic benefits are likely to flow in. (XXV) Costs of obtaining a contract and costs to fulfill a contract Where the incremental cost incurred by the Company to acquire the contract is expected to be recovered, it is recognized in the form of contract acquisition cost as an asset. The contract acquisition cost for which the amortization period does not exceed one year shall be directly included in the current gain and loss as incurred. The costs incurred by the Company for performing the contract, if not within the applicability scope of relevant standards relating to inventories, fixed assets or intangible assets, can be recognized as an asset within the contract performance cost if the following conditions are met: 183 / 269 Full Text of 2023 Annual Report 1. The cost is related to a current contract or a contract to be obtained, including direct labor cost, direct material/manufacture cost (or similar costs), cost to be undertaken by the customer and other costs incurred under the contract; 2. The cost increases the resources available to the Company to fulfill performance duties in the future; 3. The costs are expected to be recovered. Assets related to contract cost are amortized on the same basis as recognition of revenue of goods or services related to the asset and recognized in current gain and loss. If the book value of assets relating to contract cost is higher than the remaining consideration expected to be obtained due to the transfer of goods or services relating to the assets minus the estimated cost to be incurred, the Company accrues impairment reserves for the excess portion and recognizes it as an asset impairment loss. If the factors causing the impairment of the prior period change and make the remaining consideration expected to be obtained due to the transfer of goods or services relating to the assets minus the estimated cost to be incurred higher than the book value of the asset, the withdrew asset impairment provision shall be reversed and recorded in the current gains or losses, but the book value of the asset after reversion shall not exceed the book value of the asset at the reversion date under the condition of not withdrawing the impairment provision. 26. Contract costs Assets relating to contract cost comprise contract acquisition cost and contract performance cost. Where the incremental cost incurred by the Company to acquire the contract is expected to be recovered, it is recognized in the form of contract acquisition cost as an asset. The contract acquisition cost for which the amortization period does not exceed one year shall be directly included in the current gain and loss as incurred. The costs incurred by the Company for performing the contract, if not within the applicability scope of relevant standards relating to inventories, fixed assets or intangible assets, can be recognized as an asset within the contract performance cost if the following conditions are met: 1. The cost is related to a current contract or a contract to be obtained, including direct labor cost, direct material/manufacture cost (or similar costs), cost to be undertaken by the customer and other costs incurred under the contract; 2. The cost increases the resources available to the Company to fulfill performance duties in the future; 3. The costs are expected to be recovered. Assets related to contract cost are amortized on the same basis as recognition of revenue of goods or services related to the asset and recognized in current gain and loss. If the book value of assets relating to contract cost is higher than the remaining consideration expected to be obtained due to the transfer of goods or services relating to the assets minus the estimated cost to be incurred, the Company accrues impairment reserves for the excess portion and recognizes it as an asset impairment loss. If the factors causing the impairment of the prior period change and make the remaining consideration expected to be obtained due to the transfer of goods or services relating to the assets minus the estimated cost to be incurred higher than the book value of the asset, the withdrew asset impairment provision shall be reversed and recorded in the current gains or losses, but the book value of the asset after reversion shall not exceed the book value of the asset at the reversion date under the condition of not withdrawing the impairment provision. 27. Government grants 1. Government grants are recognized when both of the following conditions are met: (1) the Company is able to meet the conditions attached to the government grants; (2) the Company can receive government grants. In the 184 / 269 Full Text of 2023 Annual Report case of a monetary asset, the government subsidies shall be measured according to the amount received or accrued. In the case of a non-monetary asset, the government grants shall be measured at fair value; where the fair value cannot be reliably obtained, it shall be measured in accordance with the nominal amount. 2. Judgment basis and accounting method for asset-related government grants Government grants or subsidies that are required by government documents to be used for the acquisition or other formation of long-term assets are classified as asset-related government grants. If the government documents are not clear, judgment shall be made on the basis of the basic conditions that must be met to obtain the grants, and those that are based on the acquisition, construction or other formation of long-term assets are treated as asset-related government grants. Government grants relating to the assets are either written off against the book value of the relevant assets or recognized as deferred income. The government grants recognized as deferred income shall be recorded in the gain and loss on a reasonable and systematic basis over the service life of relevant assets. The government grants measured according to notional amount shall be directly included in current gain and loss. If the relevant asset has been sold, transferred, retired or damaged before the end of the service life, the balance of the relevant deferred income that has not been allocated will be transferred into the current gain and loss of asset disposal. 3. Judgment basis and accounting method for income-related government grants Government grants other than those related to assets will be classified into income-related government grants. For government grants that include both the asset-related and the income-related components, it is difficult to distinguish between government grants that are asset-related or income-related and such grants are generally classified as asset-related. Income-related government grants of the Company are used for compensation for relevant costs & expenses or losses in subsequent periods, which are recognized as deferred income, and recorded in current gain and loss or offset against relevant costs in the period of recognition of relevant costs, expenses or losses. Government grants for compensation for incurred relevant costs and expenses or losses are directly included in current gain and loss or offset against relevant costs. 4. The government grants related to the daily business activities of the Company shall be recorded into other incomes or written down related costs and expenses according to the economic and business nature. Government grants not related to the daily activities of the Company are recorded in non-operating incomes and expenses. 5. Accounting treatment method for policy-based preferential loans with discounted interest (1) Where the Treasury disburses the discount interest funds to the lending bank, and the lending bank provides loans to the Company at preferential policy interest rates, the Company shall use the actual amount of loans received as the entry value, and calculate the borrowing costs based on the principal and the preferential policy interest rate. (2) If the Treasury allocates the discount interest funds directly to the Company, the discount interest will be used to offset the borrowing costs. 28. Deferred tax assets/deferred tax liabilities 1. Depending on the difference between the book value and the tax base of assets or liabilities (the difference between the tax base and the book value if the tax base of items not recognized as assets or liabilities can be determined based on tax laws), the deferred income tax assets or deferred income tax liabilities shall be calculated and recognized based on the applicable tax rate during the expected asset recovery or liability settlement period. 2. Deferred income tax assets shall be recognized to the extent of probable taxable income used for deducting temporary deductible difference. On the balance sheet date, if there is concrete evidence indicating that it is likely to obtain enough taxable income in the future to offset temporary deductible difference, the deferred income tax assets that were not recognized in previous accounting periods should be recognized. 185 / 269 Full Text of 2023 Annual Report 3. At the balance sheet date, the Company should recheck the book value of deferred income tax assets. If it is unlikely to obtain enough taxable income to offset gains generated from the deferred income tax assets, then it is necessary to write down the book value of deferred income tax assets. If it is likely to obtain enough taxable income, the deducted amount shall be recovered. 4. The current income taxes and deferred income taxes of the Company are recorded as income tax expense or income in the current gains or losses, excluding income taxes arising from: (1) business combination; (2) transactions or events recognized directly in owner’s equity. 5. When both following conditions are met, the Company will list the deferred income tax assets and deferred income tax liabilities as net amount after offset: (1) When the Company has the legal right to settle the income tax assets and income tax liabilities of the Company in the current period with net amount; and (2) the deferred income tax assets and deferred income tax liabilities are related to the income tax levied by the same tax collection and management department from the same subject of tax payment or from different subjects of tax payment but the subject of tax payment involved intends to settle the current income tax assets and current income tax liabilities with the net amount or obtain the assets and liquidate the liabilities simultaneously in each future important period when the deferred income tax assets and deferred income tax liabilities are written back. 29. Lease (1) Accounting treatment method of lease as the lessee 1. The Company as lessee On the commencement date of the lease term, the Company recognizes the lease with a lease term of no more than 12 months and without the purchase option as a short-term lease; and recognizes the lease with lower value when a single leased asset is brand new as a low-value asset lease. In case of a sublease or expected sublease of lease asset, the original lease will not be deemed as a low-value asset lease. For all short-term leases and low-value asset leases, the Company will recognize the lease payment in the relevant asset cost or current gain and loss under the straight-line method during each period of the lease term. In addition to the above short-term leases and low-value asset leases under simplified treatment, the Company recognizes the right-of-use assets and lease liabilities for the lease on the commencement date of the lease term. (1) Right-of-use assets The right-of-use assets shall be initially measured at cost. The cost includes: 1) the initial measurement amount of the lease liability; 2) the amount of lease payment made on or before the commencement date of lease term, net of the relevant amount of used lease incentives (if any); 3) the initial direct expenses incurred by the lessee; 4) expected cost to be incurred by the lessee for the purpose of disassembly and removal of lease assets, restoration of the site where leased assets are located or restoration of leased assets to the status as agreed in lease terms. The Company will use the straight-line method to calculate the depreciation of the right-of-use assets. Where it is reasonably certain that the ownership of the leased assets can be obtained at the expiry of the lease term, the leased assets shall be depreciated by the Company over its remaining service life. Where it is not reasonably certain that the ownership of the leased assets can be obtained at the time the term of the lease expires, the Company shall accrue the depreciation within the shorter of the lease period and the remaining service life of the leased assets. (2) Lease liabilities On the commencement date of the lease, the Company recognizes the present value of outstanding lease 186 / 269 Full Text of 2023 Annual Report payments as lease liabilities. In calculating the present value of the lease payments, the Company adopts the interest rate embedded in the lease as the discount rate. If the Company is unable to determine the interest rate embedded in the lease, it will adopt the incremental borrowing rate as the discount rate. The difference between the lease payment and its present value is treated as unrecognized financing expenses, on which the interest expenses are recognized at the discount rate of the present value of the lease payment during each period of the lease term and included in the current gain and loss. The variable lease payments not included in the measurement of lease liabilities shall be included in current gain and loss when actually incurred. After the inception of the lease, the Company measures lease liabilities again according to the present value of the lease payments after the change, and adjusts the book value of the right-of-use asset accordingly in case of changes in the actual fixed payment amount, the expected payable amount of the guarantee residual value, the index or ratio used to determine the lease payment amount, the purchase option, and evaluation result or the actual exercise situation of the lease renewal option or the termination option. Where the book value of the right-of-use asset has been reduced to zero, but a further reduction is required for the lease liabilities, the remaining amount shall be included in the current gain and loss. (2) Accounting treatment method of lease as the lessor 1. The Company as lessor At the inception of the lease, a lease that transfers in substance almost all risks and rewards related to the ownership of leased assets is classified as a financing lease by the Company. Except for the financing lease, others are treated as the operating lease. (1) Operating lease During each period of the lease term, the Company recognizes the lease receipts as rental income under the straight-line method, and the initial direct costs incurred are capitalized and amortized on the same basis as the recognition of rental income, which is included in the current gain and loss by installment. Variable lease payments the Company acquired in connection with operating leases that are not included in the lease receipts are recognized in the current gain and loss when actually incurred. (2) Financing lease At the inception of the lease, the Company recognizes the financing lease receivables based on the net lease investment (the sum of the unsecured residual value and the present value of the lease collection not received on the first date of the lease term and discounted at the interest rate implicit in the lease), and derecognizes the financing lease assets. During each period of the lease term, the Company calculates and recognizes the interest income at the interest rate implicit in the lease. The variable lease payments obtained by the Company that are not included in the measurement of the net lease investment are included in the current gain and loss when actually incurred. 2. After-sale leaseback (1) The Company as lessee According to the Accounting Standards for Business Enterprises No.14-Revenue, the Company evaluates and determines whether the asset transfer in the after-sale leaseback transaction belongs to sales. If the asset transfer in the after-sale leaseback transaction belongs to sales, the Company will measure the right-of-use assets formed by after-sale leaseback according to the part of the book value of the original assets related to the right-of-use obtained by leaseback, and only recognize the relevant gains or losses for the right transferred to the lessor. If the asset transfer in the after-sale leaseback transaction does not belong to sales, the Company will continue to recognize the transferred assets, and at the same time recognize a financial liability equal to the transferred income, 187 / 269 Full Text of 2023 Annual Report and conduct accounting treatment for the financial liability according to the Accounting Standards for Business Enterprises No.22-Recognition and Measurement of Financial Instruments.

Risks Relating to Financial Instruments 1. Various risks arising from financial instruments The Company conducts risk management to seek the appropriate balance between the risks and benefits from its use of financial instruments and to mitigate the adverse effects that the risks of financial instruments have on the Company’s financial performance. Based on this objective, the Company’s basic policy for risk management is to confirm and analyze all kinds of risks faced by the Company, set up an appropriate risk bottom line, conduct risk management, and monitor all risks promptly and reliably to limit risks within a specific range. The Company faces various risks related to financial instruments in its daily activities, mainly including credit risk, liquidity risk and market risk. The Management has deliberated and approved the policies governing such risks, as outlined below. (I) Credit risk Credit risk refers to the risk that may bring financial loss to one party of the financial tool caused by the other party’s failure to perform its obligations in the contract. 1. Practice of credit risk management (1) Evaluation method of credit risk On each balance sheet date, the Company assesses whether the credit risk of relevant financial instruments has increased significantly since initial recognition. When confirming whether the credit risks have increased significantly since the initial recognition, the Company considers reasonable and well-founded information, including qualitative and quantitative analysis based on the Company’s history data, external credit risk ratings and forward-looking information, without incurring additional costs or efforts. Based on a single financial instrument or a combination of financial instruments with similar credit risk characteristics, the Company compares the default risks of the financial instruments on the balance sheet date with the default risks on the initial recognition date so as to determine changes in the expected default risks of financial instruments during the duration. When one or more of the following quantitative and qualitative criteria is/are triggered, the Company considers that the credit risks of financial instruments have increased significantly: 240 / 269 Full Text of 2023 Annual Report 1) The quantitative criteria mainly refer to that the probability of default of the remaining duration on the balance sheet date increases by more than a certain proportion compared with the initial recognition. 2) The qualitative criteria mainly include significant adverse changes in the debtor’s business or financial situation, and existing or expected changes in the technical, market, economic or legal environment, which will have a significant adverse impact on the debtor’s repayment ability to the Company, etc. (2) Definition of default and credit-impaired assets When a financial instrument meets one or more of the following conditions, the Company defines the financial asset as a default, and its standard is consistent with the definition of credit impairment: 1) The debtor has major financial difficulties; 2) The debtor violates the binding provisions on the debtor in the contract; 3) The debtor is likely to go bankrupt or undergo another financial restructuring; 4) The creditor gives the debtor concessions that the debtor would not make under any other circumstances due to economic or contractual considerations related to the debtor’s financial difficulties. 2. Measurement of expected credit loss Key parameters for measuring expected credit loss include the probability of default (PD), loss given default (LGD) and exposure at default (EAD). The Company has taken into account the quantitative analysis and forward-looking information of historical statistical data (such as counterparty rating, guarantee method, collateral type and repayment method), and established the PD, LGD and EAD models. 3. For the reconciliation between the opening balance and the closing balance of the provision for loss of financial instruments, please see notes V (I) 3 and V (I) 6 of the financial statements for details. 4. Credit risk exposure and credit risk concentration The credit risk to the Company mainly comes from monetary funds and accounts receivable. In order to control the above related risks, the Company has taken the following measures respectively. (1) Monetary fund The Company deposits bank deposits and other monetary funds in financial institutions with high credit rating, so its credit risk is low. (2) Receivables The Company regularly evaluates the credit of customers who trade by credit. According to the credit evaluation results, the Company chooses to trade with recognized customers with good credit and monitors their accounts receivable balance to ensure that the Company will not face significant bad debt risk. Since the Company only conducts transactions with recognized third parties with good credit, no collateral is required. Credit risk concentration is managed according to customers. As of December 31, 2023, the Company has a certain credit concentration risk, because 53.41% (December 31, 2022: 57.71%) of the Company’s accounts receivable are from the top five customers ranking in terms of balance. The Company holds no collateral or other credit enhancement for the balance of accounts receivable. The maximum credit risk exposure of the Company is the book value of each financial asset on the balance sheet. (II) Liquidity risk Liquidity risk refers to the risk of occurrence of capital shortage when the Company fulfills its obligations settled by delivering cash or other financial assets. It may result from the inability to sell financial assets at fair value as soon as possible; or because the other party is unable to repay its contractual debts; or from debts due in advance; or from the inability to generate expected cash flow. In order to control this risk, the Company comprehensively uses various financing means, such as bill 241 / 269 Full Text of 2023 Annual Report settlement and bank loan, and adopts the method of the appropriate combination of long-term and short-term financing methods to optimize the financing structure, so as to maintain the balance between financing sustainability and flexibility. The Company has obtained bank credit lines from a number of commercial banks to meet working capital needs and capital expenditure.

The interest-bearing financial instruments with fixed interest rates expose the Company to fair value interest rate risk, and the interest-bearing financial instruments with floating interest rates expose the Company to cash flow interest rate risk. The Company determines the ratio of fixed interest rate and floating interest rate financial instruments according to the market environment, and maintains an appropriate combination of financial instruments through regular review and monitoring. The cash flow interest rate risk faced by the Company is mainly related to the bank borrowings with floating interest rates. As of December 31, 2023, the bank borrowings with a floating interest rate of the Company are RMB 242 / 269 Full Text of 2023 Annual Report 157,889.1476 million, and EUR 60.7927 million (December 31, 2022: RMB 138260.1218 million). Under the assumption that other variables remain unchanged, assuming that the interest rate changes by 50 benchmark points, will not have a significant impact on the total profits and shareholders’ equity. 2. Foreign exchange risk Foreign exchange risk means a risk that the fair value or future cash flow of a financial instrument fluctuates due to a change in the foreign exchange rate. The risk of exchange rate changes faced by the Company is mainly related to the Company’s foreign currency monetary assets and liabilities. For foreign currency assets and liabilities, in case of short-term imbalance, the Company will buy and sell foreign currencies at the market exchange rate when necessary to ensure that the net risk exposure is maintained at an acceptable level. The Company’s monetary assets and liabilities in foreign currencies at the end of the period are detailed in note V (V) 1 of Notes to Items in the Consolidated Financial Statements. XIII.
