Section III Management Discussion and Analysis I. Industry in which the company operated during the reporting period The Company shall comply with the disclosure requirements for petrochemical industry specified in Guidelines No. 3 for Self-Regulation of Listed Companies of Shenzhen Stock Exchange - Industry Information Disclosure (I) Overview Hengyi Petrochemical (Stock code: 000703.SZ) is a global leading enterprise in the integration of the “refining-chemical engineering-chemical fibre” industry chain. Since its establishment, the company has always focused on its core business, taking "one drop of oil, two threads" as the core of its strategic policy. It has laid out the Brunei refining project in a forward-looking manner, opening up the "last kilometer" of the industrial chain from refining to chemical fibre. This has formed the unique "polyester + polyamide" dual "polyamide" drive mode in China. The company continues to give full play to the comprehensive competitive advantages of "upstream and downstream synergy, domestic and overseas linkage" and has constructed an integrated columnar balanced industrial structure of upstream, midstream, and downstream industry chains. 18 2023 Annual Report of Hengyi Petrochemical Co., Ltd. In order to deepen the core competitiveness of its main business, HengYi Petrochemical has continued to push forward the strategic transformation from "Industry Hengyi" to "Technology Hengyi" in recent years, and has built up a system of independent intellectual property rights around the company's core business areas, steadily pushing forward the technological research and development of high-value added products and the innovative optimization of processes. We will steadily push forward the technological research and development of high value-added products, as well as the innovation and optimization of processes, in order to lay a solid foundation for the company's sustainable development. Driven by digitalization and intelligent construction, the company is marching towards the ambitious goal of becoming a leading domestic and world-class private multinational industrial group of "refining, chemical industry and chemical fibre". (II) Industries in which the company’s three major business operate In 2023, economics in the China achieved steady growth against the backdrop of a faltering global economic recovery and intensifying international geopolitical conflicts. According to the National Bureau of Statistic, China’s gross domestic growth (GDP) grew by 5.2% year-on-year (y-o-y) in 2023, and total retail sales of consumer goods for the year increased by 7.2% y-o-y. Focusing on the chemical industry, the boom in the chemical industry was first depressed and then rose in the first three quarters of 2023, before falling back to the median level for the year in the fourth quarter. As of 29 December 2023, China chemical product price index was 4,635, lower than the median value of 4,696 and the average value of 4,657 in the past ten years, still at the low level of the industry cycle. 19 2023 Annual Report of Hengyi Petrochemical Co., Ltd.

Refining and petrochemical industry In 2023, under the geopolitics, the expectation of interest rate hike in the United States, production cuts by major crude oil producers, banking crisis and other factors, the Brent crude oil futures price is generally running in the range of 70-95 US dollars per barrel, and the overall trend is wide oscillation. Brent crude oil futures average daily price chart ($/bbl) 100 95 90 85 80 75 70 65 2023-01 2023-04 2023-07 2023-10 2024-01 20 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Data sources: CCF (1) Southeast Asia refined oil market demand gap is large; supply tension situation is difficult to improve in the short term IEA reporting refers to Asia remains an important region dominating oil demand. From the demand side, Southeast Asia has richer oil and gas resources, but due to the shortage of infrastructure investment, instead of becoming the largest net import market of refined oil in the world, besides, Australian also need import refined oil. In addition, the implementation of the new IMO standard in 2020, a greater impact on the global shipping industry, Singapore as a major shipping base, bunker fuel sulphur content of shipping fuel is mandatory restrictions, some MGO (marine diesel) need to replace marine fuel oil, stock replacement space release, Southeast Asia diesel demand is expected to continue to increase. According to the latest forecast released by the International Monetary Fund in January 2024, ASEAN's GDP growth rate in 2024 will remain high, of which Indonesia is expected to grow at a rate of 5.0%, and the Philippines is expected to grow at a rate of 6.0%, which is still significantly higher than the global level, and the favourable trend of the economic expectations may further drive the growth of demand for refined chemical products. From the supply side, compared with the surplus state of domestic refined oil supply, the gap in the Southeast Asian refined oil market is larger, with an overall surplus of supply over demand. According to Platts data, from 2020 to 2023, more than 30 million tons of refining capacity in Southeast Asia and Australia will be withdrawn from the market due to public health events and energy structure transformation. Some refineries in Southeast Asia are still facing challenges such as early construction of equipment, outdated technology, poor management, and heavy government subsidies burden. 21 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Additionally, with the tightening of global environmental protection policies, refineries are reluctant to expand production, and capital expenditure plans are becoming more cautious. Refiners and chemical companies are also hesitant to increase production, further limiting the future growth of refinery capacity. According to the IEA forecast, the refining capacity in Southeast Asia is expected to remain unchanged until 2028. (2) Refinery earnings expected to rise as refined oilcrack spreads remain high in Singapore market As a benchmark for refinery profitability in Southeast Asia, looking at the refinedoil cracking spread in the Singapore market from 2022 to the present, in 2022, the refined oil cracking spread fluctuated significantly due to multiple factors such as geopolitical tensions, drastic fluctuations in crude oil prices, and weak downstream demand. In 2023, the reshaped global refined oil market supply and demand structure, influenced by geopolitical factors, remained relatively stable, resulting in a reduced amplitude of the refined oil cracking spread. There was a noticeable boost starting in the second quarter. Since 2024, the refined oil cracking spread in Singapore has remained at high levels, indicating the potential for sustained and robust improvement in refinery profitability in Brunei.

Data sources: Platts platform 2. PTA industry PTA is one of the important bulk organic raw materials, widely used in various aspects of the national economy such as chemical fibers, light industry, electronics, and construction. 95% of domestic PTA demand is used in the polyester industry. China now dominates the worldwide PTA market since it is the largest producer and consumer of PTA worldwide because to its ongoing improvement of PTA independent production capacity. The CCF statistics shows that in 2023 China's actual new PTA capacity expanded by 10 million tons, with a capacity growth rate that dropped from 18.5% in 2020 to 12.8% in 2023. CCF anticipated that in 2024 China's PTA capacity commissioning would continue to slow down and that the rate of capacity expansion would drop to 6%. Furthermore, PTA exports are increasing consistently and China's market share in the world PTA market has progressively grown. Chinese PTA capacity accounted for almost 76% of Asian PTA output in 2023; the foreign PTA sector did not add any new units. China's PTA capacity will continue to rise in the future years, accounting for the percentage of Asia and the world. The demand for polyester goods is really high in overseas markets such Bangladesh, Turkey, and other nations; China's PTA exports are still rising. 3. Polyester industry Polyester fibres are mainly used in clothing, home textiles and technical textiles, etc. The development of the industry is closely related to the downstream demand of the textile and chemical fibre industry. 23 2023 Annual Report of Hengyi Petrochemical Co., Ltd. (1) The downstream demand outlook has significantly improved, driving a steady release of demand for polyester products. The domestic economy steadily recovered in 2023, and the textile and apparel industries' boom much improved, propelling polyester market production and sales and exhibiting strong development against the backdrop of a slowing down of crude oil price swings. According to the National Bureau of Statistics, China's retail sales of consumer goods overall increased by 7.2% year over year in 2023, up 7.4 percentage points from the prior year; retail sales of clothing, shoes, hats and textile goods in China increased by 12.9% year over year, up 19.4 percentage points from the prior year. Expanding, there was a clear marginal comeback trend in China's retail sales of textiles, needles, headgear, clothes, and footwear in the second half of 2023. The demand is continuing maintaining a better trend, demonstrating a strong momentum of recovery, and the chain growth rate has been growing positively since August, particularly in November when it reached a new record high of 24 percent. Exports in 2023 are little less than in 2022 because of the sluggish recovery of the world economy, geopolitics, supply chain adjustment, and other factors influencing the total export volume of textiles and apparel. China's cumulative textile and apparel exports in 2023 were US$293.64 billion, down 8.1 percent from the same time last year, but the total value remains high and the export volume is still higher than in 2019. The development of China's textile and garment industries still heavily depends on the international market. 24 2023 Annual Report of Hengyi Petrochemical Co., Ltd.

In the textile and apparel industry under the high degree of boom, polyester fibre demand is expected to release, the production of high-load operation, production growth rate hit a record high in the past thirteen years. According to CCF data, in 2023, polyester fully drawn yarn demand growth is strong, and the demand growth rate is much higher than the growth rate of production capacity, which is conducive to the continuous optimization of the industry's competitive landscape. According to CCF data, the apparent demand for polyester fully drawn yarn in 2023 was 36.68 million tons, up 22.8% year-on-year, with the demand side of the boom significantly improved; the net new capacity of 3.85 million tons during the year, the annual production capacity reached 51.68 million tons, an increase of 8.0% year-on-year; the annual production totalled 40.6 million tons, an increase of 22.7% year-on-year. 25 2023 Annual Report of Hengyi Petrochemical Co., Ltd.

(II) Operation model 1. Procurement model The Company mainly purchases raw materials through direct negotiation with manufacturers or traders. It selects competitive suppliers to establish long-term and stable cooperative relations, on the basis of which it decides the transaction price according to market conditions. The Company adopts a centralized procurement strategy, integrating resources from Brunei and domestic operating suppliers and increasing resource sharing efforts, so as to enhance the Company's own bargaining 37 2023 Annual Report of Hengyi Petrochemical Co., Ltd. power. The raw materials required for production of the Company are mainly purchased from major petrochemical products and crude oil suppliers at home and abroad. When selecting raw material suppliers, the Company first considers the quality of their products and the stability of supply. While ensuring the above, the Company will also give priority to suppliers with competitive prices to reduce production costs. The Company will sign annual supply contracts with major suppliers, regarding the supply in the relevant year of their products to the Company in accordance with international or domestic market prices at the time of actual supply as per the quantity agreed in the contracts. The main procurement process for auxiliary materials is basically the same as that for raw materials. 2. Production model For polyester products, the Company arranges production mainly according to the production plan formulated in advance. In specific implementation, the annual production plan will be subdivided into monthly production plan, and then the Production Department will make necessary adjustments to the monthly production plan according to the market feedback and change information provided by the Sales Department before finalizing the monthly production plan and arranging production. The Company's refined oil and chemical products (PX, benzene, etc.) are mainly produced by Hengyi Brunei. Usually, it will adjust the process and parameters to control the output of specific products, such as refinedoil and chemical products, according to the market demand. 38 2023 Annual Report of Hengyi Petrochemical Co., Ltd.

The Company generally adopts direct sales, and directly concludes sales contracts with customers. The settlement mode is usually “payment before delivery”, or “collect on delivery”. 4. Business model of supply chain service business The company’s supply chain service business mainly includes trade business and supporting logistics related services. (1) Trading business Petrochemical industry is a cyclical industry. On the one hand, the supply side of raw materials is susceptible to factors such as upstream suppliers' production capacity, operation stability of the plant and start-up time of the new plant. On the demand side, especially in the downstream polyester business, sales have typical seasonal characteristics. Meanwhile, chemical raw materials and finished products are very dependent on the stability of port facilities and international logistics transportation. On the other hand, the prices of products in the petrochemical industry chain are affected by the price of terminal crude oil, showing wide fluctuations. Therefore, in order to 40 2023 Annual Report of Hengyi Petrochemical Co., Ltd. ensure production and operation, strengthen supply chain stability and reduce the risk of price fluctuation, petrochemical enterprises need to smooth supply and demand and hedge risks through trade business in procurement and sales. The company has never carried out trade in products unrelated to its main business, insisting on the principle of positioning trade business to serve the main business, and trading varieties around the main business and core products. Among them, crude oil, refined oil and other oil products are the main raw materials and products of Brunei project of the company, PX is the raw material of the company's main product PTA, PTA and MEG are the main raw materials of the company's polyester products. The above trading business is conducive to the Company's access to spot market information and revenue through trading, as well as the Company's need for inventory management of raw materials and products, which can stabilize the supply chain and hedge against the risk of price fluctuations. (2) Logistics warehousing and other operations The company's logistics segment provides raw material and product transport services for the upstream and downstream industries of Hengyi Petrochemical. Its business covers raw material transport, product transport, foreign trade transport and international transport, etc. The company is deeply engaged in the domestic market and is gradually moving towards the overseas market, and its business scope involves international sea transport and land transport.

Polyester esterification polycondensation process In the process of polyester esterification, the raw material PTA, ethylene glycol and catalyst solution are continuously sent into the slurry preparation tank according to the specified proportion. After they enter the esterification reactor, the esterification rate can reach about 95%-96% by controlling the reaction temperature at an appropriate level. By means of gear pump discharging and pressurization, the polyester melt produced from esterified materials after Polycondensation and final polycondensation is filtered by melt filter, and is distributed through a specially designed melt distribution system. Part of it is sent to the spinning device for melt direct spinning, and the other part is sent to the flake production system for ribbon casting and pelletizing. The specific flow chart of polyester esterification, polycondensation and other reactions is as follows: 43 2023 Annual Report of Hengyi Petrochemical Co., Ltd. 4. Production flow of POY/FDY The production process of POY and that of FDY are basically the same. The polyester melt is connected and transported to the device from the outlet of the melt distribution valve of the polyester device, and then is divided into two systems through the melt three-way valve. On the way, it is pressurized by the melt booster pump, and then sent to the melt distribution valve after cooling-down by the melt cooler. The polyester melt from the melt distribution system enters the spinning chamber insulated by steam phase heat medium at a certain temperature and is delivered to the spinning assembly after metering by a metering pump. The melt pipe is equipped with a freezing valve to ensure that the spinning position can be independently started and stopped. After the melt is filtered and pressed by the filter layer again in the spinning assembly, it is ejected from the spinneret in a thin stream and solidified into yarns under the condition of constant temperature and humidity. The yarn is oiled by the tanker, and then through the network nozzles, it is rolled into a yarn tube in the winding machine. POY and FDY products were prepared under highspeed winding ranging from 2,500m/min to 5,100m/min. Blending Oil + water Oil Cooling 5. Production flow of DTY The POY yarn on the yarn tube rack is wound into a DTY yarn tube and becomes a finished product after it passes through yarn guide, feeding roller, texturing heater, cooling, drafting, false twister, feeding roller in the middle, network, heater, delivery 44 2023 Annual Report of Hengyi Petrochemical Co., Ltd. roller and oil roller. 6. Production flow of staple fibre Polyester staple fibre is a kind of fibre that is transported to the spinning machine through melt, spun into shape, cut into fibres of different lengths after drafting, crimping and heat setting, and then packed into individual packages.

Effectively reduce the company's costs and expenses, achieve synergistic improvement of operational efficiency, and ensure the company's sustainable, stable and healthy development. (IV) Risks faced by the company and countermeasures 1. Macroeconomic risk The company is engaged in the business of petrochemical and polyester fibre products production and sales, petrochemical and polyester chemical fibre industry and the world economy and China's economic development is closely related to the state of the 122 2023 Annual Report of Hengyi Petrochemical Co., Ltd. economy, but also an industry closely related to national economy and people's livelihood, and the price and sales of its products are affected by macro-economic fluctuations and changes in supply and demand and other factors. With the acceleration of economic globalisation and integration, national macro-controls and cyclical fluctuations in the world economy will have an impact on the development of the industry, and if the global economic growth slows down or there is a recession, it will have a direct impact on the Company's business, operating results and financial position end demand. 2. Safety and environmental production risks As the awareness of eco-friendliness increases and the government's environmentally- friendly requirements become stricter, the Company strictly implements the Production Safety Law of the People's Republic of China, Environmental Protection Law of the People's Republic of China and other relevant laws and regulations to ensure safe and environmentally-friendly production, and earnestly fulfils our social responsibility. Since the operation of the main production entity, no major safety and eco-friendliness incidents have occurred. With the expansion of the Company's production scale and the extension of the industry chain, preventing safety and eco-friendliness accidents has become the focus of the Company's operation and management. In order to reduce industrial safety and environmental production risks, the Company strengthens subsequent investment in eco-friendliness, including but not limited to the purchase and update of equipment and facilities, the construction and implementation of organizational systems, etc. The Company will actively carry out safety standardization and acceptance work in accordance with the arrangements for the construction of Class 1, 2, and 3 national safety standards, and focus on building a safety standard management system. The Company will implement the dual-prevention work mechanism combining safety risk classification and control and hidden danger 123 2023 Annual Report of Hengyi Petrochemical Co., Ltd. investigation and management, strengthen safety training, increase safety investment, practice the strategy of promoting safety based on science and technology, promptly remove safety and eco-friendliness hazards, and eliminate all possibilities of major accidents. 3. Risk of significant fluctuations of raw materials price More than 80% of the cost composition of the industry chain in which the Company operates is determined by upstream raw materials, in particular, the price fluctuation of crude oil has a greater impact on the Company's production and operation. 2024, the price of crude oil is likely to fluctuate significantly in line with the international situation, geopolitics, etc., which will in turn affect the price change of various products in the industry chain, aggravate the uncertainty of raw material costs and operating costs, and may bring about greater fluctuations in the Company's efficiency. The Company will continue to optimise its inventory strategy to reduce the adverse impact caused by price fluctuations of crude oil and other raw materials. 4. Environmental protection risks The production and operation of the Company must comply with multiple environmental protection laws and regulations related to air, water quality, waste disposal, and public health and safety, obtain relevant environmental protection permits, and accept inspections from relevant national environmental protection departments. In recent years, the Company has invested a large amount of funds and technical strength in the transformation of environmental protection equipment and production processes, and has treated and discharged pollutants in accordance with national environmental protection requirements. However, with the promotion of vertical integration of the industrial chain of listed companies, the expansion of production scale, and the possibility of stricter environmental protection standards and broader and stricter 124 2023 Annual Report of Hengyi Petrochemical Co., Ltd. pollution control measures being implemented in China or Brunei in the future, the Company's environmental protection costs and management difficulties will also increase. 5. Risk of exchange rate and interest rate fluctuations The main operations of the Company's subsidiary, Hengyi Brunei, are located outside of China, and its main business is settled in US dollars. The exchange rate and interest rate between the settlement currency and RMB may fluctuate in line with changes in the international political and economic environment, and is subject to a certain degree of uncertainty. With the expansion of the Company's overseas business layout and the increase in overseas sales revenue in the future, the Company's asset position and operating results are exposed to risks arising from exchange rate fluctuations. The Company's interest rate risk mainly comes from bank borrowings. The Company, through establishing a good cooperative relationship with banks, has made reasonable designs for credit limits, credit varieties and credit terms to ensure sufficient bank credit limits to meet the Company's various long and short-term financing needs and to reasonably reduce the risk of interest rate fluctuations.

(2) Impairment test process of goodwill In November 2018, with an amount of RMB 2,105 million, the Company purchased all 418 2023 Annual Report of Hengyi Petrochemical Co., Ltd. stocks of Zhejiang Shuangtu New Materials Co., Ltd., and amortized the merger prices in accordance with relevant accounting standards. On the combination date, the fair value is RMB 1,883,134,400 for the acquiree’s net identifiable assets. As a result, an amount of RMB 221,865,600 goodwill is formed in the consolidated accounting statement. This year, the Company assessed the recoverable amount of goodwill and conducted impairment tests on various asset groups related to goodwill. In the process of goodwill impairment test, the Company determined the composition of the assets of the asset groups related to the goodwill reflected in the Company’s consolidated financial statements and their book value of RMB 1,750,023,000 based on the consolidated financial statement as on December 31, 2023 and the assets and operating conditions of the merged party Shuangtu. It is found after impairment test that the present value of the expected future cash flow of this goodwill and related asset group on December 31, 2023 was RMB 1,856,000,000, and no impairment occurred. Details are as follows: Currency unit: 10,000 Item Book number of consolidated statements Fixed assets 132,855.52 Construction in progress 555.77 Intangible assets 19,357.76 Long-term unamortized expenses 46.69 Goodwill recognized in consolidated statements 22,186.56 Subtotal of book value of asset groups containing 175,002.30 goodwill Vale of goodwill not recognized as attributable to minority 0.00 shareholders’ equity Total adjusted book value of asset groups containing 175,002.30 goodwill 419 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Item Book number of consolidated statements Present value (recoverable amount) of the estimated 185,600.00 future cash flow of the asset group Note: For the present value (recoverable amount) of the expected future cash flow of the asset groups above, the results of assessment set out in the HYZXPBZ [2024] No. A01-0022 Asset Appraisal Report issued by Beijing Huaya Zhengxin Assets Appraisal Co., Ltd. on April 12, 2024 was used. The recoverable amount of the asset groups above is determined according to the present value of the expected future cash flow. Based on its current operating conditions, business characteristics and market supply & demand and upon an overall analysis and consideration of various factors such as residual service life of main assets included in the asset group, the acquirer is estimated to enter a stable period in 2028. Therefore, the predictive period is determined from January 2024 to December 2028 (five years in total), and the discount rate of 10.27% is adopted. Important assumptions for goodwill impairment test: ① Assumption of orderly transaction: Orderly transaction refers to the transaction that related assets or liabilities have usual marketing activities within a period of time prior to the measurement date. ② Assumption of open market: It means that assets can be traded freely in the fully competitive market, and that its price depends on independent buyer’s and seller’s value judgment under certain market supply and demand conditions. It is an assumption about the conditions of the target assets market and about the influence of assets under relatively complete market conditions. ③ Going concern assumption: Assume no unforeseeable factor leading to a failure to continue operations, when the entrusted asset group is continuously operated in accordance with the current situation, purpose, usage mode and management level on the base date; 420 2023 Annual Report of Hengyi Petrochemical Co., Ltd. ④ No significant change in the existing editions of applicable national laws & regulations and macro-economic situation; No unforeseeable significant change in external economic environment (e.g. interest rate, exchange rate, tax base & rate and policy collection expenses); ⑤ Assume that the Company’s current business model can be continuously maintained in the future, and predict the future cash flow of assets based on current asset conditions, excluding the prediction of the future cash flow related to restructuring or modification that will probably occur in the future and that has not been promised yet; ⑥ Assume that cash inflow and outflow of the asset group occur in the middle of the year after the assessment base date. ⑦ Assume that the management of the acquired party after the assessment base date is responsible, stable, and capable of assuming their positions. 20.

VIII. Risks related to financial instruments The Company’s main financial instruments include monetary capital, financial assets measured by fair value and whose changes included in current profits and losses, loan, accounts receivable and accounts payable. For detail description of different financial instruments, please refer to related items in Note V. Risks related to these financial instruments and corresponding risk management policies taken by the Company to mitigate such risks are described in detail as follows. The Company’s management shall manage and monitor these risk exposures, so as to control above risks within a limited scope. 473 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Sensitivity analysis techniques are used by the Company to analyze probable influence of rational and probable changes in risk variables on current profit and loss or stockholders' equity. Risk variables seldom change separately. Correlation between different variables will have great effect on the final influence amount of a risk variable. Therefore, the following contents are stated upon the assumption that change of every variable takes place independently. (I) Risk management objective and policy The Company’s risk management objective is to appropriately balance risk and income, minimize adverse impact of risk on the Company’s business performance, and maximize benefits of its stockholders and other equity investors. Based on this risk management objective, the Company’s basic strategy for the risk management is to determine and analyze different risks, set up an appropriate risk tolerance baseline for risk management, supervise various risks in time and reliably, and control all risks within a limited scope. 1. Market risk (1) Foreign exchange risk Foreign exchange risk refers to the risk of loss generated by fluctuations in exchange rate. The Company’s foreign exchange risk is mainly correlated with USD and BND. Except the Company’s several subsidiaries that purchase and sell in USD, other main business activities of the Company shall be settled in RMB. On December 31, 2022, most assets and liabilities of the Company are of RMB balance (excluding the following assets or liabilities in USD and BND). Foreign exchange risk generated by assets and liabilities in such foreign currency may influence the Company’s business performance. 474 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Ending balance Balance at the end of previous Item year USD BND USD BND Cash and cash equivalents 490,067,263.72 11,371,328.85 581,686,909.13 8,184,622.74 Accounts receivable 608,193,939.66 53,547,754.04 817,630,221.72 54,599,853.33 Other receivables 8,924,007.85 5,274,274.23 8,028,333.81 3,631,010.18 Long-term receivables 518,788.46 0.00 518,788.46 0.00 Short-term loans 1,286,616,775.17 0.00 1,493,172,376.69 177,944,666.40 Accounts payable 567,677,254.66 3,191,737.90 1,116,259,414.13 4,823,807.10 Other payables 3,140,568.35 3,848,062.37 4,323,553.62 1,935,823.58 Non-current liabilities due 188,339,242.85 1,385,745.68 251,125,031.52 1,334,939.91 within one year Long-term loans 950,220,000.00 0.00 1,326,310,000.00 0.00 Long-term payables 0.00 0.00 1,897,602.19 0.00 Lease liabilities 0.00 83,328,762.28 0.00 81,899,040.00 The Company pays close attention to the influence of exchange rate fluctuations on its foreign exchange risk. In accordance with relevant provisions, the Company shall not be engaged in any transaction of foreign exchange derivatives for the purpose of speculation. Based on normal production and management, all foreign exchange derivatives transactions shall depend on specific business, so as to avoid and prevent corresponding exchange rate or interest rate risks. Foreign exchange risk sensitivity analysis: The Company’s foreign exchange risk is mainly correlated with changes in the exchange rate between USD & BND and RMB. The following table shows sensitivity analysis upon the assumption of 1% exchange rate change between foreign currency and RMB related to the Company. In the process of sensitivity 475 2023 Annual Report of Hengyi Petrochemical Co., Ltd. analysis made by the management, 1% increase or decrease is deemed as rational reflection of probable exchange rate change scope. On the basis of above assumption, under the circumstance that other variables are maintained unchanged, the influence of probable rational changes in exchange rate on current profit & loss and stockholders' equity (before tax) is shown as follows: Influence on Current Profit & Loss and Item Fluctuation in Stockholders' Equity (Before Tax) Exchange Rate Current Period Previous Period Monetary assets (USD) 78,455,351.19 98,052,113.77 Appreciation of RMB Monetary liabilities (USD) -212,197,255.78 -292,031,805.33 by 1% Net influence -133,741,904.59 -193,979,691.55 Monetary assets (USD) -78,455,351.19 -98,052,113.77 Depreciation of RMB Monetary liabilities (USD) 212,197,255.78 292,031,805.33 by 1% Net influence 133,741,904.59 193,979,691.55 Monetary assets (BND) 3,774,437.20 3,442,381.07 Appreciation of RMB Monetary liabilities (BND) -4,933,812.66 -13,887,508.83 by 1% Net influence -1,159,375.46 -10,445,127.77 Monetary assets (BND) -3,774,437.20 -3,442,381.07 Depreciation of RMB Monetary liabilities (BND) 4,933,812.66 13,887,508.83 by 1% Net influence 1,159,375.46 10,445,127.77 (2) Interest rate risk – cash-flow change risk The Company’s risk at fair value change of financial instruments caused by interest rate change mainly comes from: When the financial market interest rate is at a downward trend, the Company cannot enjoy cost saving for fixed-rate loans that are brought by interest-rate reduction. On the contrary, cost will be increased for its loans at floating interest rates due to rate hiking when the financial market 476 2023 Annual Report of Hengyi Petrochemical Co., Ltd. interest rate is at an upward trend. The Company’s short- term loans and mid-and- long-term loans account for approximately 50% of its liabilities with interest respectively. Moreover, interest is at a fixed rate for most short-term loans, and floating interest rates for mid-and-long-term loans. According to the Company’s management, therefore, the Company’s interest rate risk – fair value change risk is insignificant under the current tendency of interest rate change in macroscopic financial market. At present, there is no interest rate hedging policy in the Company. Interest rate risk sensitivity analysis: Interest rate risk sensitivity shall be analysed upon the following assumption: influence of market interest rate changes on interest income or expense of financial instruments at variable interest rates. For short-term loans, sensitivity analysis shall be based on continuously circulating borrowing of such loan in an integral accounting year. During sensitivity analysis by the management, increase/ decrease in 50 base points will be deemed as reasonable reflection on the feasible range of interest rate change. On the basis of above assumption, under the circumstance that other variables are maintained unchanged and that the interest rate is increased/decreased by 50 base points, probably rational interest rate changes may have the following influence on current profit & loss and stockholders' equity (before tax): Profit increase in Profit decrease in Item Interest rate change current period current period Short-term loans and mid-and- long-term liabilities at fixed Increase in every 50 base points at an interest rate 227,932,255.55 -- upward trend of interest rate 477 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Short-term loans and mid-and- Decrease in every 50 base points at a long-term liabilities at fixed -- 227,932,255.55 downward trend of interest rate interest rate Mid-and-long-term liabilities at Increase in every 50 base points at an -- 102,274,200.18 floating interest rates upward trend of interest rate Mid-and-long-term liabilities at Decrease in every 50 base points at a 102,274,200.18 -- floating interest rates downward trend of interest rate (3) Other price risks The Company’s investments classified into held-for-trading financial assets shall be measured by fair value on the balance sheet. Therefore, the Company undertakes the risk of related assets price variation The Company has established an investment management department, in which members are assigned to closely monitor the price variation of investment products. In consideration of the necessity of futures investment and relevant features of leverage risk, the Company’s BOD authorized the president to set up a futures leading group, and authorized this group to take charge of the Company’s futures. In addition, the Company also formulated the train of thought of futures, specified to establish a futures trading group in the Investment Management Department (responsible for organization and implementation of transaction in accordance with decisions made by the futures trading group), specified to establish a futures settlement group in the Financial Management Department (responsible for such works as funds management, accounting treatment, transaction confirmation and settlement management), and specified to establish a futures supervision group in the Auditing Department (responsible for futures trading risk management & control and periodic review for transaction behaviors). In order to strengthen its internal control over futures and to effectively prevent and relieve probable risks in the transaction process, the Company also formulated the Futures Business 478 2023 Annual Report of Hengyi Petrochemical Co., Ltd. Management System, requiring all futures business participants to operate in strict accordance with related provisions and processes. All personnel participating into futures business in the Company have received special training, and have an adequate understanding of corresponding features and risks of futures involved. According to the Company’s directors, therefore, its price risk has been mitigated already. 2. Credit risks Credit risk refers to the risk of financial loss on the other party as one party of financial instruments fails to perform its obligations. The Company’s credit risk mainly comes from bank deposit and receivables. In order to control above risk, the Company took the following measures. In order to lower its credit risk, the Company established a group for determination of credit limit and for credit approval. The policy of payment before delivery is adopted for unapproved clients. In addition, the Company shall also review on every balance sheet date recovery of every single receivable, making sure to withdraw adequate bad debt reserves for unrecyclable funds. According to the Company’s management, therefore, its credit risk has been reduced substantially. The Company’s working capital is saved in the bank at high credit rating.

XI. Commitments and Contingencies 1. Contingent liabilities arising from pending litigation and arbitration and their financial impact ① Criminal case of Wang XX and related civil action cases in Zhejiang Shuangtu Since October 21, 2018, Zhejiang Shuangtu has received the notice from more than ten clients (including Haiyan Yixiao Knitting New Materials Co., Ltd.). After the payment, the clients never received goods delivered by Zhejiang Shuangtu, and could not get contact with Wang XX. For the reason of the failure of Zhejiang Shuangtu to deliver after their payment, Haiyan Yixiao Knitting New Materials Co., Ltd., Tonglu Yueheng Knitting Clothing Co., Ltd. and Yiwu Zijing Clothing Co., Ltd. submitted a case to the court. According to its self-inspection, Zhejiang Shuangtu has already received the payment of above clients for goods, and finished related activities (including delivery and issuance of sales invoice) as per the sales order. All clients failing to receive the goods were handled by Wang XX, a salesman in Zhejiang Shuangtu. Then, the clients could not get contact with Wang XX. On November 11, 2018, Zhejiang Shuangtu reported the case to the criminal investigation brigade subordinate to Dajiangdong Industry Cluster District Suboffice of Hangzhou Public Security Bureau. The case has been accepted already. On April 13, 2019, Zhejiang Shuangtu received a notice from the 492 2023 Annual Report of Hengyi Petrochemical Co., Ltd. public security organ: Wang XX was arrested. Both the three civil cases related to Wang XX and the contract dispute case with Haiyan Yixiao Knitting New Materials Co., Ltd. were opened to a court session on December 3, 2018. The court has not made a judgment yet. As Wang XX’s criminal case is involved, Tonglu Yueheng Knitting Clothing Co., Ltd. positively withdrew the contract dispute case, and would decide how to solve after the criminal case was handled.
