These statements are based on assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and future developments, as well as other factors we believe are appropriate in particular circumstances.

D.Risk Factors

Our business and financial condition and results of operations are subject to various changing business, competitive, economic, political and social conditions in China and worldwide. In addition to the factors discussed elsewhere in this annual report, the following are some of the important factors that could cause our actual results to differ materially from those projected in any forward-looking statements.

Our business is vulnerable to downturns in the general economy and industries in which we operate or which we serve. A significant reduction in demand could materially and adversely affect our business, financial condition and results of operations.

Demand for our products depends on the general economy and level of activity and growth in the industries where we operate or serve. Adverse development in economic and market conditions, such as a significant economic downturn or a downturn in the commodity sector or the financial markets, could have a material adverse effect on our business, financial condition, results of operations and the price of our ordinary shares or ADSs. Development of the relevant industries is subject to various factors, including but not limited to market fluctuations of prices of commodities, general political or economic conditions, technology development, government regulations and investment plans and changes in domestic and global production capacity, many of which are beyond our control.

1

We are unable to predict cycles of the global and domestic economies. Concerns over inflation, energy costs, geopolitical issues, trade tensions, the availability and cost of credit, unemployment, consumer confidence, declining asset values, capital market volatility and liquidity issues have created difficult operating conditions for us in the past and may continue to do so in the future. For example, since 2018, there were continuing trade tensions between the U.S. and China, resulting in increased tariffs and escalating tensions between the two countries. On January 15, 2020, the two parties signed the China-U.S. phase-one economic and trade agreement. Since then, the PRC government and the U.S. government have granted tariff exemptions on certain goods. However, it is still unclear when future phase negotiations between the two countries will begin and whether there will be further trade agreements following such negotiations. It is also unclear if future disputes will occur or the two countries will be able to negotiate the issues to restore a mutually beneficial economic and trade cooperation. Future actions or escalations by either the U.S. government or the PRC government could have a material adverse effect on the business environment in general, global, Chinese and/or U.S. economic conditions and the stability of global, Chinese and/or U.S. financial markets, which in turn, may adversely affect our business, financial condition and results of operations. In addition, on November 12, 2020, the President of the United States signed Executive Order 13959 (as subsequently amended on January 13, 2021 and June 3, 2021, the “Executive Order”), which prohibits certain transactions in securities of certain entities listed in the annex to the Executive Order (each, a “Restricted Entity”). Currently, neither we nor Chinalco are on the list of Restricted Entities. However, if the Executive Order is further amended, or the Office of Foreign Assets Control of the U.S. Department of Treasury exercised its power pursuant to the Executive Order, to include us or Chinalco as a Restricted Entity in the future, U.S. persons as defined under the Executive Order may be prohibited from purchasing our securities. As a result, the value and liquidity of our ADSs may be materially and adversely affected, which may lead to significant volatility in our ADS trading price. Furthermore, the PRC government has, from time to time, adjusted its monetary, fiscal and other policies and measures to manage the rate of growth of the economy or the overheating and overcapacity in certain industries or markets. In addition, the global outbreak of COVID-19 and the efforts to contain it have negatively impacted the global economy and financial markets. For further details of the impact of outbreak of COVID-19 on the general economy, please refer to “– Our business may be materially and adversely affected by the COVID-19 pandemic.”

The global economy began to recover from the COVID-19-induced recession in 2021 and the commodities market had an unparalleled growth. Due to the recovery of demand for aluminum globally, in 2021, the average spot price of alumina on the Australian FOB increased by 21.8% to US$331 per tonne and the average international cash price for primary aluminum on the LME increased by 45.5% to US$2,480 per tonne. During the same period, the average spot price of alumina in the domestic market increased to RMB2,798 per tonne, representing an increase of 19.7% compared to 2020. Although the overall trend of the industries we are in was upward in 2021, there is no assurance that there will not be any further and significant fluctuations, which may materially and adversely affect our business, financial condition and results of operations. Recently, the Russia-Ukraine military conflict has caused, and continues to intensify, significant geopolitical tensions in Europe and across the world. The resulting economic sanctions imposed by the United States, the European Union, the UK and other countries may continue to significantly impact supply chains, lead to market disruptions including significant volatility in commodities’ prices, and bring heightened near-term uncertainty to the global financial system. Escalation of the Russia-Ukraine conflict could lead to other additional impacts which may adversely affect our business, such as disruption of international trade flows, extreme market pricing volatility, with particular impact on the energy sector, industrial supply chains, shipping, and regulatory and contractual uncertainty, and increased geopolitical tensions around the world. These factors could disrupt the global markets in ways that are difficult to predict and estimate in advance as to their potential impact on our business, financial position, or operational results.

As a result of the foregoing, the global and domestic economic conditions or any particular industry in which we operate or which we serve may grow at a lower-than-expected rate or even experience a downturn. Uncertainty about future economic conditions makes it challenging for us to forecast our results of operations, make business decisions and identify risks that may affect our business. If we are not able to timely and appropriately adapt to changes resulting from the difficult macroeconomic environment, our business, financial condition and results of operations may be materially and adversely affected.

Volatility in the prices of alumina, primary aluminum, other non-ferrous metal and other commodities may adversely affect our business, financial condition and results of operations.

The prices of the products we produce and trade, including alumina, primary aluminum, other non-ferrous metal and coal products, have experienced significant fluctuation historically and are expected to continually fluctuate in response to general economic conditions, supply and demand, the level of inventories, interruption caused by unforeseen international or domestic events such as global outbreak of COVID-19, uncertainty of or changes in domestic or foreign laws or policies and many other factors, which are beyond our control.

2

We price our alumina and primary aluminum products by reference to international and domestic market prices, and domestic supply and demand, each of which may fluctuate beyond our control. We may not be able to effectively respond to a sudden fluctuation in alumina or primary aluminum prices. For example, due to the recovery of demand for aluminum globally, in 2021, the average spot price of alumina on the Australian FOB increased by 21.8% to US$331 per tonne and the average international cash price for primary aluminum on the LME increased by 45.5% to US$2,480 per tonne. During the same period, the average spot price of alumina in the domestic market increased to RMB2,798 per tonne, representing an increase of 19.7% compared to 2020, and the average spot prices of primary aluminum at SHFE increased by 34.2% to RMB18,953 per tonne. In 2021, the average external selling prices for our self-produced alumina and primary aluminum, regardless whether the sales were recognized in our trading segment, were RMB2,785 per tonne and RMB19,099 per tonne, respectively, representing an increase by 13.4% and 34.8%, respectively, as compared to the prices in 2020. Nevertheless, the prices of alumina and primary aluminum may decline due to, among other things, decrease in market demand of those products and any slowdown of economic growth in China. Because our prices are affected by a variety of factors, most of which are beyond our control, we may not be able to respond promptly to the fluctuation in alumina or primary aluminum prices in international market or domestic market. There is no assurance that there will not be any further and significant fluctuations in prices of our key products, including alumina and primary aluminum, which may materially and adversely affect our business, financial condition and results of operations. In addition, since our profit margin for trading non-ferrous metal products and coal products is based on price fluctuations in the short term, we need to make the correct prediction of the price fluctuations of these commodities on the markets to maintain our profit margin. If market price fluctuations on the market do not match our prediction, we may incur substantial losses.

In addition, as we generate profit from the differences between the purchase and sales prices of the non-ferrous metal products and the coal products we deal in, significant fluctuations in these prices may cause the value of the outsourced products in transit or in inventory to decline, and if the carrying value of our existing inventories exceeds the market price in the future periods, we may need to make additional provisions for our inventories’ value, which may have a material and adverse effect on our profit level and other financial performance. See Note 13 to our audited consolidated financial statements for information about our inventories. As a result, any significant fluctuation in market prices for these commodities could materially and adversely affect our business, financial condition and results of operations.

Our business requires substantial capital expenditures that we may not always be able to obtain at reasonable costs and on acceptable terms.

Our plans to upgrade and expand our production capacity will require substantial capital expenditures. For the years ended December 31, 2019, 2020 and 2021, our total capital expenditures were approximately RMB11.8 billion, RMB4.6 billion and RMB4.7 billion, respectively. We expect our estimated capital expenditures in 2022 to be a total of approximately RMB6.8 billion. See “Item 4. Information on the Company – D. Property, Plants and Equipment – Our Expansion” and “Item 5. Operating and Financial Review and Prospects – B. Liquidity and Capital Resources – Capital Expenditures and Capital Commitments” for details of our expansion and capital expenditures. We may also need additional funding for debt servicing, working capital, other investments, potential acquisitions and joint ventures and other corporate requirements.

We may need to seek external financing, such as bank and other loans as well as bond offerings, to satisfy our capital needs if cash generated from our operations is insufficient to fund our capital expenditures or if our actual capital expenditures and investments exceed our plans. Our ability to obtain external financing at reasonable costs and on acceptable terms is subject to a variety of factors, such as our credit ratings, financial market conditions and our past or projected financial performance. Although we have been profitable in recent years, we cannot guarantee that we will not incur losses in the future, in which case the rating agencies may downgrade our credit ratings. In addition, if financial markets experience significant volatility and disruption, it may result in a decrease in the availability of liquidity and credit for borrowers and increase in interest rate or other financing cost. Failure to obtain sufficient funding at reasonable costs and on acceptable terms for our development plans could delay, reduce the scope of, or eliminate future activities or growth initiatives and adversely affect our business and prospects.

Our business may be materially and adversely affected by the COVID-19 pandemic.

Since the end of 2019, COVID-19, a disease caused by a novel strain of coronavirus, has spread in China and globally, and the World Health Organization declared the COVID-19 outbreak a pandemic in March 2020. The COVID-19 pandemic has led the governments and other authorities around the world, including China, to impose measures intended to control its spread, including quarantines, restrictions on travel and public gatherings, temporary closure of certain businesses and facilities. While still continuing, the COVID-19 pandemic, as well as efforts to contain it, has caused significant economic and financial disruptions around the world, including disruption on manufacturing operations, logistics and global supply chains and significant volatility and disruption of financial markets. We have taken measures to control and manage the impact of COVID-19, including measures to protect health and safety of our employees, maintain ventilation system and promote vaccinations among all employees. However, if the virus, in particular the Delta and Omicron variants thereof, further spreads worldwide, including China or other jurisdictions in which we, our suppliers or customers operate or have property or projects, or further control measures are adopted and continue to stay in place in these or other regions, we may face further disruptions on our normal operation, sales, project construction, supply chain and transportation channel, labor shortage and other limitations on our business activities due to restrictions on our employees’ ability to travel, infection of management and employees, suspension or closure of facilities, additional costs arising from precautionary infection control and hygienic measures, and other impacts, which could be material and adverse to our business, financial condition and results of operations. For example, China has recently experienced upticks in cases that have prompted selective restrictions in affected regions such as Shanghai.

In addition, the market prices of primary aluminum and alumina have been volatile since the COVID-19 outbreak. Although, because of the recovery of the downstream business activities in China and globally, the market prices of primary aluminum and alumina have increased in 2021, there is no assurance that the demand for primary aluminum and alumina will not be weakened by the COVID-19 pandemic any more, and any volatility or decreases of the market prices of primary aluminum and alumina may result in reduction of our revenue and profit, increase of our inventory amount and other material and adverse impacts on our financial condition and results of operations.

If the global public health crisis caused by COVID-19 pandemic continues, it may have an adverse impact on the global and China’s economies, which may, among other things, exacerbate turbulence in commodity market, discourage or disrupt investment and production, increase total inventories of primary aluminum or other products in the industry, bring more uncertainty to the consumption of aluminum-made products and the prices of primary aluminum and alumina, and cause other adverse impacts on the industry we are in. An economic downturn including financial market disruption, or a market perception that this situation may occur or develop, may also cause increase of financing costs, or reduce available sources of financing for operation or expansion. In addition, significant financial market volatility and uncertainty may adversely affect the market prices of our ordinary shares and ADSs. Credit risks of customers and suppliers and other counterparty risks may also increase. These factors may materially and adversely affect our business, financial condition and results of operations. We may also experience negative effects from other future health epidemics or outbreaks beyond our control. These events are impossible to forecast and difficult to prevent. Any of these events could have a material adverse effect on our results of operations and financial condition.

Our operations consume substantial amounts of electricity, and our profitability may decline if electricity costs rise or if our electricity supplies are interrupted.

Our operations consume substantial amounts of electricity. Although we generally expect to meet the electricity consumption requirements for our alumina refineries and primary aluminum smelters from a combination of internal and external sources, our results of operations may be materially and adversely affected by any significant increase in electricity costs or interruptions in electricity supply.

Cost of electricity is the principal production cost in our primary aluminum operations. Our average electricity cost per kWh (including tax) of our primary aluminum smelters increased by 27% from 2020 to 2021. There is no assurance that the electricity costs will not further increase in the future. For instance, in 2021, the PRC government issued certain policies related to electricity pricing that could increase our electricity cost. See “Item 4. Information on the Company – B. Business Overview – Regulatory Overview – Electricity Supply and Price” for further details. If we are unable to pass on increases in energy costs to our customers, our operating margin, financial condition and results of operations could be materially and adversely affected.

With the implementation of the policy of “carbon dioxide peaking and carbon neutrality,” a series of policies have been introduced to control both the total amount and intensity of energy consumption and restrict the energy-intensive and high-emission industries, resulting in drastic market fluctuations and a sharp increase in production costs. A series of stringent measures such as electricity consumption restriction and production restriction and restriction on approval of projects have been adopted in various regions, resulting in large-scale production reduction in the industry, which led to a shortage of supply and aggravated the uncertainty of new or resumed production capacity in the second half of 2021. We cannot assure you that our production capacity will not be further affected by such policies, the occurrence of which could have a material adverse impact on our business, financial condition and results of operations.

In addition, interruptions in the supply of electricity can result in costly production shutdowns, increased costs associated with restarting production and the waste of production in progress. A sudden loss of electricity, if prolonged, can cause damage to or the destruction of production equipment and facilities. In such an event, we may need to expend significant capital and resources to repair or replace the affected production equipment to restore our production capacity. In the past, various regions across China experienced shortages and disruptions in electricity supply, especially during peak demand summer season or under severe weather conditions. For instance, certain subsidiaries of our Company were affected by electricity shortage due to electricity consumption restriction in the second and third quarters of 2021 and the suspended production volume reached a maximum of 3% of our total production capacity in October and November 2021. We cannot assure you that our operations will not suffer from shortages or disruptions in electricity supply, the occurrence of which could have a material adverse impact on our business, financial condition and results of operations.

Our operations consume substantial amounts of coal, and our operations may be adversely affected if we are not able to procure sufficient coal or if coal prices rise significantly.

We rely heavily on coal as our energy and fuel source in our operations. As we increase our alumina refining capacity, our consumption of coal will increase accordingly. If we are not able to obtain the amount of coal needed for our production due to a shortage of coal, constraints on coal transportation or any other reason, we may be forced to reduce our production output or suspend our alumina refining operations, which could materially and adversely affect our financial condition and results of operations. Although we have acquired equity interest in a number of coal mines, we expect to continue to rely substantially on third-party coal suppliers for the supply of coal. Our average purchase price per unit tonne of thermal coal increased by approximately 52.4% in 2021 from the level in 2020. See “Item 5. Operating and Financial Review and Prospects – A. Operating Results – Overview – Factors Affecting Our Results of Operations – Manufacturing Costs.” There is no assurance that the coal prices will not further increase or fluctuate. If we are unable to pass on increases or otherwise significant fluctuations in coal prices to our customers or offset price increases through productivity improvements, our operating margin, financial condition and results of operations could be adversely affected.

Our business and industry may be affected by the development of alternative energy sources and climate change.

Our operations consume substantial amounts of coal, the combustion of which generates significant greenhouse gas and other pollutants, and negatively contributes to climate change. A number of governments or governmental bodies have introduced or are contemplating legislative and regulatory changes in response to the potential impacts of climate change. These regulatory mechanisms may impact our operations directly or indirectly through our customers or supply chain. For example, the deepening of supply-side structural reform and the policy of “carbon dioxide peaking and carbon neutrality” have urged the industry in which we operate to optimize the energy consumption structure, reduce energy consumption, and develop deep-processing products with high added values. We may have to increase our capital expenditures in order to comply with such revised or new legislation or regulations, and changes to our profit or loss may occur due to increased or decreased demand for our products and indirectly due to changes in costs of goods sold, which may adversely affect our results of operations and financial condition.

In addition, we have invested in coal mining operations. Although revenues attributable to our energy segment accounted for only approximately 2.8% of our total revenues in 2021 (after elimination of inter-segment sales), we might still be affected by any change on the PRC thermal power industry, which have relied on coal as main source of fuel. The PRC thermal power industry may be affected by the development of alternative energy sources, climate change and global environmental factors. In particular, pursuant to the environmental protection goal set in China’s 14th Five-Year Plan, the PRC government plans to continue to encourage the development of new energy sources from 2021 to 2025. As such, alternative energy industries may rapidly develop and gradually gain mainstream acceptance in the PRC and the rest of the world. If alternative energy technologies continue to develop and prove suitable for wide commercial application in the PRC and overseas, demand for conventional energy sources, such as coal, could be reduced. Such reduction in demand for coal could have a material adverse effect on the coal mining industry and, consequently, negatively affect our business, results of operations and financial condition.

We may not be able to continue competing successfully in the markets in which we operate.

In 2021, we supplied approximately 43.8% of our total production of alumina to our own smelters and sold substantially all of the remaining self-produced alumina and all of our self-produced primary aluminum to our domestic customers. Our alumina (with chemical alumina products included) and primary aluminum production represented approximately 23.6% and 10.1%, respectively, of total domestic production in China in 2021. We face competition from both domestic and international alumina and primary aluminum producers. Our principal competitors are major domestic refineries and smelters. These producers compete with our alumina and primary aluminum operations on the basis of product cost, quality and pricing. In addition, we face increasing competition from international alumina and primary aluminum suppliers as a result of the elimination of tariffs on imports of primary aluminum and alumina into China. See “Item 4. Information on the Company – B. Business Overview – Competition” for further details.

Increasing competition in our product markets may reduce our selling prices or sales volumes, which will have a material adverse effect on our financial condition and results of operations. If we are unable to price our products competitively, maintain or increase our current share of China’s alumina and primary aluminum markets or otherwise maintain our competitiveness, our financial condition, results of operations and profitability could be materially and adversely affected.

Our overseas expansion exposes us to political and economic risks, commercial instability and events beyond our control in the countries in which we plan to operate.

We have overseas projects from time to time. For example, in 2020, we completed the construction of the Boffa Project, a project for the construction and development of a bauxite mine located in Boffa, Guinea. Although the Boffa Project has been completed and put into production, due to uncertainties involved in the overseas projects, we cannot assure you that all of our overseas expansion or investments will be successful or that we will not suffer foreign exchange losses in connection with our overseas investment.

In addition, operations in the overseas markets may also expose us to a number of risks including expropriation and nationalization of our assets in foreign countries, civil unrest, acts of terrorism, war, or other armed conflict; shortages of construction equipment and materials; severe weather conditions; social security, public health and safety, labors and construction safety and similar issues; epidemic diseases and infectious diseases; natural disasters; inflation; currency fluctuations, devaluations and conversion restrictions; confiscatory taxation or other adverse tax policies, governmental activities that limit or disrupt markets, restrict payments or limit the movement of funds, governmental activities that may result in the deprivation of contractual rights; lack of a well-developed legal system that makes it difficult to enforce our contractual rights; uncertainties in laws and policies; and governmental activities that may result in the inability to obtain or retain licenses required for operations. For example, in September 2021, President of Guinea was captured by the country’s armed forces in a coup. While our Boffa Project has not been materially impacted as of the date of this annual report, we cannot assure you that it will not be adversely affected given the fluid situation in Guinea.

Our profitability and operations could be adversely affected if we are unable to obtain a steady supply of raw materials at competitive prices.

Historically, the price for bauxite, our most important raw material for alumina production, has been volatile. We obtain bauxite for our operations from our mines and external suppliers. See “Item 4. Information on the Company – B. Business Overview – Raw Materials – Alumina – Supply.” The extents to which we procure bauxite from each of these sources affect the security of our supply or cost of bauxite. The supply of bauxite could be affected by various factors, including geographic conditions of bauxite mines, government policies, market prices and competition, many of which are beyond our control. We rely on overseas suppliers to obtain a portion of bauxite we use for production. Indonesia used to be a major source of our imported bauxite. As a result of the ban imposed by the Indonesia Government on the exportation of unprocessed bauxite and nickel, since January 2014, we have not been able to import bauxite from Indonesia for the use of our alumina refineries in China, and our operation of bauxite mining in Indonesia has been suspended since September 2014. See “Item 4. Information on the Company – B. Business Overview – Our Mines” for more details of our bauxite mines in Indonesia. If we exhaust our stockpiles or our procurement of bauxite from external suppliers is interrupted for any reasons, and cannot find an alternative source of bauxite at competitive prices, our financial condition, results of operations and profitability could be adversely affected.

In addition, our results of operations can be affected by increases in the cost of other raw materials and other key inputs such as energy. If we cannot obtain a steady supply of key raw materials at competitive prices, our financial condition and results of operations could be materially and adversely affected.

6

Any transportation interruption or any material increase in our transportation costs could have a material adverse effect on our business, financial condition and results of operations.

Our operations require the reliable transportation of raw materials and supplies to our refining and smelting sites and finished products to our customers. Our alumina and primary aluminum products are mainly transported by rail and trucks. There is no assurance that we can always enjoy sufficient transportation capacity or we will not experience transportation interruption in the future. Furthermore, natural disasters, severe weather conditions and outbreak of epidemic diseases and infectious diseases may cause interruption to the transportation system, which could in turn affect the transportation of our products. Please refer to “– Our business may be materially and adversely affected by the COVID-19 pandemic” for further details of the impact of COVID-19 pandemic on the transportation system. In addition, any changes in fuel prices or fuel supply may be unpredictable and beyond our control. There is no assurance that shortage of fuel will not occur in the future. Any surge in fuel prices or shortage of fuel supply may lead to increases in our operation and transportation costs. If we are unable to make timely deliveries due to logistical and transportation disruptions, or transfer the increased costs to our customers, our production, reputation and results of operations may be adversely affected.

Estimates of mineral reserves and mineral resources are uncertain and the volume and grade of minerals actually extracted may vary from our estimates.

Our estimates of mineral reserves and mineral resources have been prepared in accordance with the disclosure requirements of Subpart 1300 of U.S. Securities and Exchange Commission Regulation S-K (“Regulation S-K 1300”). Compliance with Regulation S-K 1300 may be subject to varying interpretations in some cases due to their lack of specificity, which could result in continuing uncertainty regarding compliance matters and substantial costs associated with compliance.

There are numerous uncertainties inherent in mineral estimates. Such estimates are, to a large extent, based on assumed prices for the commodities we produce, primarily bauxite and coal, and interpretations of geologic data obtained from drill holes and other exploration techniques, which may not necessarily be indicative of future results. Our mineral estimates are based on the latest available geological and geotechnical studies. We conduct ongoing studies of our mining properties to optimize economic values and to manage risk. Valid estimates made at a given time may significantly change when new information becomes available.

Estimates of mineral reserves, or the cost at which we anticipate the mineral reserves will be recovered, are based on assumptions, such as prices of alumina, aluminum and coal and other economic inputs. Changes to such assumptions may require revisions to reserve estimates which could affect our asset carrying values and may also negatively impact our future financial condition and results. We revise our mine plans and estimates of recoverable proven and probable mineral reserves as required in accordance with the latest available studies. Until mineral reserves are actually mined and processed, the quantity of minerals and grades must be considered as an estimate only.

Additionally, the term “mineral resources” does not indicate recoverable proven and probable mineral reserves as defined by Regulation S-K 1300. Estimates of mineral resources are subject to further exploration and evaluation of development and operating costs, grades, recoveries and other material factors, and, therefore, are subject to considerable uncertainty. Certain mineral resources may not meet the threshold for mineral reserve modifying factors, such as engineering, legal and/or economic feasibility, that would allow for the conversion to mineral reserves. Accordingly, no assurance can be given that the estimated mineral resources not included in mineral reserves will become recoverable proven and probable mineral reserves.

The estimation of mineral resources and reserves is a subjective process that is partially dependent upon the judgment of the qualified person preparing such estimates. The process relies on the quantity and quality of available data and is based on knowledge, mining experience, statistical analysis of drilling results and industry practices. If the market prices for the commodities we produce decline from assumed levels, if production costs increase or recovery rates decrease, or if applicable laws and regulations are adversely changed, we can offer no assurance that the mineral reserves can be mined or processed profitably. If we determine that certain of our estimated recoverable proven and probable mineral reserves have become uneconomic, this may ultimately lead to a reduction in our aggregate reported mineral reserves, which could have a material adverse effect on our business, financial condition and results of operations.

Our previous adjustments of our business segments and historical results may not be indicative of our future prospects.

In 2013, we entered into a new business segment, the energy segment, through acquisition of Ningxia Energy. In the past few years, we have streamlined our existing business to focus on the productions of alumina and primary aluminum. For instance, in December 2018, we acquired 50% equity interests in Shanxi Huaxing through the Shanghai United Assets and Equity Exchange at a price of approximately RMB2,665.2 million from Baotou Transportation Investment Group Co., Ltd. Upon completion of the acquisition, Shanxi Huaxing became a wholly-owned subsidiary of the Company. The acquisition is conducted for purposes of enhancing our profitability and is in line with our strategic layout of alumina and aluminum business, as the increase of our shareholding in Shanxi Huaxing, an alumina plant, is expected to enhance the synergy with our primary aluminum production in Shanxi, where we have newly added production capacity of primary aluminum.

There is no assurance that we will enter into a new business segment or continue to streamline our existing business as we have done so in the past. Moreover, we cannot assure you that the benefit of entering into a new business segment or streamlining our existing business will be fully realized as expected or at all.

While our revenue increased by 45.0% from RMB185,990.6 million in 2020 to RMB269,748.2 million in 2021, primarily due to the year-on-year increase in the prices of alumina and electrolytic aluminum, the financial performance was driven by a wide range of factors, many of which are out of our control or may not be sustainable or indicative of future growth or performance, such as the prices of our products and raw materials. As a result, our historical results may not be indicative of our future prospects and results of operations.

Our failure to successfully manage our business expansion, including our expansion into new areas of business, would have a material adverse effect on our results of operations and prospects.

We have made investments in business expansion in line with our development strategy through organic growth, acquisitions and joint ventures. In addition, we may, from time to time and when we deem appropriate, expand into new industries which we believe have synergies with our existing operations.

Our expansion has created, and will continue to place, substantial demand on our resources. Managing our growth and integrating the acquired businesses will require us to, among other things:

● comply with the laws, regulations and policies applicable to the acquired businesses, including obtaining timely approval for the construction or expansion of production and mining facilities as required under the relevant laws of PRC and foreign jurisdictions;

● maintain adequate control on our business expansion to prevent, among other things, project delays or cost overruns;

● accumulate expertise and experience in managing the new businesses;

● gain market acceptance for new products and services and establish relationships with new customers and suppliers;

● achieve sufficient utilization of new production facilities to recover costs;

● manage relationships with employees, customers and business partners during the course of our business expansion and integration of new businesses;

● attract, train and motivate members of our management and qualified workforce to support successful business expansion;

● access debt, equity or other capital resources to fund our business expansion, which may divert financial resources otherwise available for other purposes;

● divert significant management attention and resources from our other businesses; and

● strengthen our operational, financial and management controls, particularly those of our newly acquired subsidiaries, to maintain the reliability of our reporting processes.

8

Any significant difficulty in meeting the foregoing or similar requirements could delay or otherwise constrain our ability to implement our expansion plans, or result in failure to achieve the expected benefits of the combination or acquisition or write-offs of acquired assets or investments, which in turn would limit our ability to increase operational efficiency, reduce marginal manufacturing costs or otherwise strengthen our market position. Failure to obtain the intended economic benefits from the business expansion could adversely affect our business, financial condition, results of operations and prospects. In addition, we may also experience mixed results from our expansion plans in the short term.

Furthermore, there is no assurance that we will be able to identify attractive acquisition targets, obtain favorable deal terms in any acquisition, secure applicable governmental approvals for any proposed investments, accurately estimate the mineral resources and reserves of these acquisition targets or obtain the necessary funding to complete such acquisitions on commercially acceptable terms or at all. Acquisitions may result in the incurrence and inheritance of debts and other liabilities, assumption of potential legal liabilities in respect of the acquired businesses, and incurrence of impairment charges related to goodwill and other intangible assets, any of which could harm our business, financial condition and results of operations. In particular, if any of the acquired businesses fail to perform as we expect, we may be required to recognize a significant impairment charge, which may materially and adversely affect our business, financial condition and results of operations. As a result, there can be no assurance that we will be able to achieve the strategic purpose of any acquisition, the desired level of operational integration or our investment return target.

Our joint ventures and strategic investments may not be successful.

We may from time to time enter into joint ventures or make strategic investments to grow our business and operations. For example, we have participated in joint ventures and strategic investments in coal mining, in line with our development strategy to diversify our product offering and partially offset our future energy costs. In addition, we have acted as joint venture partner or strategic investor in certain projects which engage in primary aluminum and aluminum alloy manufacturing to diversify our product offering, strategically position ourselves along the industrial chain and facilitate our enterprise transformation and upgrade. If our joint ventures, strategic investments or other investments experience fluctuation in performance or incur losses, our business, financial condition and results of operations may be adversely affected. For further details of certain of our joint ventures and strategic investments, please see “Item 4. Information on the Company – A. History and Development of the Company” and “Item 4. Information on the Company – D. Property, Plants and Equipment – Our Expansion.”

In addition, our joint ventures and subsidiaries which operate coal mines have been facing increasing uncertainties. While the coal price rose rapidly in the first three quarters of 2021 due to short supply, it then declined to a reasonable range in November 2021 due to the policy adjustment and increase of coal supply. If coal price further decreases in the future, the business, financial condition and results of operations of these joint ventures which operate coal mines may be adversely affected.

9

Failure to maintain optimal utilization of our production facilities will adversely affect our gross and operating margins.

During the past few years, we expanded the production capacity by completing our construction, upgrading or remolding of some of our alumina and primary aluminum production facilities. If we are able to maintain satisfactory facility utilization rates and increase our production output, this increase in our production capacity would enable us to reduce our unit costs through economies of scale, as fixed costs will be spread over a higher volume of output units. Conversely, underutilization of our existing and newly acquired or constructed production facilities may increase our marginal production costs and prevent us from realizing the intended economic benefits of our expansion.

Since 2013, we have implemented flexible production arrangements from time to time for certain alumina and primary aluminum production facilities in response to prevailing market conditions and government policies. Although we did not implement flexible production arrangements in 2021, we cannot assure you that we will not do so in the future. We may also increase our external purchases of alumina and primary aluminum for trading purposes to capitalize on fluctuating market prices and to enhance resource planning to achieve cost savings in our production. The increase in our external purchases will reduce our utilization of certain production facilities, but may not result in a proportionate decrease in fixed costs such as leases and depreciation of plant, property and equipment.

If we fail to maintain optimal utilization rates and spread fixed costs over a high volume of output units, our gross and operating margins may be adversely affected.

We may be required to record impairment charges in the future.

If business conditions deteriorate, long-lived assets need to be reviewed for possible impairment. Impairment loss needs to be recognized to the extent that the carrying amount exceeds the recoverable amount. In 2019, 2020 and 2021, we recorded impairment loss of property, plant and equipment of RMB259.4 million, RMB416.8 million and RMB2,328.1 million, respectively. In addition, we made net credit impairment of receivables of RMB171.0 million, RMB979.2 million and RMB1,384.9 million in 2019, 2020 and 2021. We cannot guarantee that we will not incur any impairment loss or our impairment loss will not increase in the future due to various reasons including, but not limited to, strategic decisions made in response to changes in economic and competitive conditions, the impact of the economic environment on our customer base and material adverse changes in our relationship with significant customers. If we record significant impairment charges, our results of operations may be materially and adversely affected.

Our mining operations have limited mine lives and eventual closure of these operations will entail costs and risks regarding ongoing monitoring, rehabilitation and compliance with environmental standards.

Our existing mining operations in the PRC and overseas have limited mine lives and will eventually be depleted. We need to perform certain procedures to remedy and rehabilitate the environmental and social impact that our mining operations have had on local communities and the environment. Remediation, rehabilitation, closure and removal of our facilities will incur various costs and are subject to various risks. The key costs and risks for mine closures include, among others, (i) long-term management of permanent engineered structures and acid rock drainage; (ii) closure in accordance with local or international environmental standards; (iii) orderly retrenchment of employees and third-party contractors; and (iv) orderly transfer of the site, its associated permanent structures and community development infrastructure and programs to new owners. There is no assurance that such closure of mines will be successful and without delays or additional costs, in which case we may be subject to increased costs, penalties or other legal or administrative actions, damages to reputation, or even suspension and cancellation of mining permits, the occurrence of which would cause a material adverse effect on our business, financial condition and results of operations.

10

Failure to discover new reserves or resources, maintain or enhance existing reserves or resources, develop new mining operations or expand our current mining operations could negatively affect our business, financial condition and results of operations.

Mining exploration is unpredictable in nature. The success of any mining exploration program depends on various factors, many of which are beyond our control. Due to the unpredictable and speculative nature of the mining industry, there is no assurance that any exploration program that we are currently undertaking or may undertake in the future will result in the discovery of valuable reserves or resources. There is no assurance that reported resources can be converted into reserves. Furthermore, actual results upon production may differ from those anticipated at the time of discovery. To access additional reserves in explored areas, we will need to successfully complete development projects, including but not limited to extending existing mines and developing new mines. There are a number of uncertainties inherent in the development and construction of any new mine or an extension of an existing mine, including but not limited to (i) the availability and timing of necessary governmental approvals; (ii) the timing and cost necessary to construct mining and processing facilities; (iii) the availability and cost of labor, utilities, auxiliary materials and other supplies and the accessibility of transportation and other infrastructure; and (iv) the availability of funds to finance construction and production activities. There is no assurance that any future exploration activities or development projects will extend the life of our existing mining operations or result in any new economic mining operations and such failure may have a material adverse effect on our business, financial condition and results of operations.

Our indebtedness could adversely affect our business, financial condition and results of operations.

We have relied, and expect to continue to rely, on both short-term and long-term borrowings to fund a significant portion of our capital requirements. As of December 31, 2021, we had approximately RMB24,506.1 million in outstanding short-term bonds and short-term bank borrowings (including the current portion of long-term bank and other borrowings) and RMB64,095.9 million in outstanding long- and medium-term bonds and long-term bank and other borrowings (excluding the current portion of these borrowings). On March 22, 2022, subject to approval at our 2021 annual general meeting that is expected to be held in 2022, our Board approved to authorize the issuance of debt financing instruments and bonds in the PRC (including various issued domestic bonds) and overseas bonds with an aggregate outstanding balance of all bonds not exceeding RMB50 billion, the term of which authorizations will commence on the date of approval at our 2021 annual general meeting and close upon the conclusion of our 2022 annual general meeting. Although we have been managing our debt and assets with the goal of maintaining our debt at an appropriate level, there is no assurance that such efforts would be successful or the level of our debt will be further decreased. Please see Note 19 and Note 44 to our audited consolidated financial statements for more detailed information about our borrowings and recent issuance of bonds and notes in 2022. This level of debt could have significant consequences on our operations, including:

● making it more difficult for us to fulfill payment and other obligations under our outstanding debt, including repayment of our debt and credit facilities should we be unable to obtain extensions for any such debt or credit facilities before they mature. Please see “Item 5 – Operating and Financial Review and Prospects – B. Liquidity and Capital Resources” for maturities of our outstanding long-term borrowings;

● reducing the availability of cash flows to fund working capital, capital expenditures, acquisitions and other general corporate purposes;

● exposing us to interest rates fluctuations on our borrowings and the risk of being unable to rollover, extend or refinance our borrowings as necessary;

● potentially increasing the cost of additional financing and making it more difficult for us to conduct equity financings in the capital markets or obtain government approvals to seek additional financing; and

● putting pressure on our ADS price due to concerns of our ability to repay our debt.

11

Our ability to meet our payment and other obligations under our outstanding debt depends on our ability to generate cash flows in the future or to refinance such debt. In 2021, we carried out capital preservation and appreciation businesses by using daily reserve fund for investments such as structural deposits. However, we cannot assure you that such capital preservation and appreciation businesses will be successful or profitable, or our business in general will generate sufficient cash flows from operations, to satisfy our obligations under our outstanding debt and to fund other liquidity needs. If we are not able to generate sufficient cash flows to meet such obligations, we may need to refinance or restructure our debt, reduce or delay capital investments, or seek additional equity or debt financing. The sale of additional equity securities could result in dilution to our ADS holders. A shortage of financing could in turn impose limitations on our ability to plan for, or react effectively to, changing market conditions or to expand through organic and acquisitive growth, thereby reducing our competitiveness. We cannot assure you that future financing will be available in amounts or on terms acceptable to us, if at all.

The instruments governing our senior debt contain covenants that restrict our ability to take certain corporate actions and pay dividends.

We issue perpetual securities from time to time to meet our capital expenditure and working capital requirements. Please refer to “Item 4. Information on the Company – A. History and Development of the Company – Senior Perpetual Capital Securities Offering” for further details.

In November 2019 and December 2020, we issued RMB1,500 million perpetual medium-term notes with an initial distribution rate at 4.20% (the “2019 Perpetual Medium-term Notes”) and RMB1,000 million perpetual medium-term notes with an initial distribution rate at 4.45% (the “2020 Perpetual Medium-term Notes”), respectively, in China. Pursuant to the terms of the 2019 Perpetual Medium-term Notes and the 2020 Perpetual Medium-term Notes, while any coupon distribution payments are unpaid or deferred, our Company cannot declare or pay dividends to shareholders or decrease the share capital, or make material fixed asset investments. Therefore, our ability to pay dividends in respect of our ordinary shares and the ADSs may be limited under certain circumstances.

In addition, if these perpetual securities are categorized as debt due to changes of accounting standard or other reasons, or if we choose to redeem these perpetual securities, our total equity may be reduced, which may be adverse to our financial condition or the price of our ordinary shares or ADSs.

The interests of our controlling shareholder who exerts significant influence over us may conflict with ours.

As of December 31, 2021, our largest shareholder, Chinalco, directly owned 29.67% of our issued share capital and indirectly owned an additional 2.49% of our issued share capital through its controlled entities. The interests of Chinalco may conflict or even compete with our interests and those of our public shareholders. Chinalco may take actions that are in the interest of its subsidiaries, associates and other related entities to our detriment. For example, Chinalco may seek to influence our decision as to the amount of dividends we declare and distribute. Any increase in our dividend payout would reduce funds otherwise available for reinvestment in our businesses and thus may adversely affect our future prospects and financial condition.

In addition, we enter into transactions with related parties, including Chinalco and its subsidiaries and associates, which provide a range of services to us, including engineering and construction services, social services, land and property leasing as well as the supply of raw and supplemental materials. See “Item 7. Major Shareholders and Related Party Transactions – B. Related Party Transactions” for detailed information. It would be difficult to find an alternative source for some services that we receive from Chinalco. Our cost of operations may increase if Chinalco, its subsidiaries and associates are unable to continue providing such services to us.

In January 2019, Yunnan SASAC transferred its 51% equity interest in Yunnan Metallurgical Group Co., Ltd. to China Copper, a wholly-owned subsidiary of Chinalco, with no consideration. As Yunnan Aluminum, an affiliated company of Yunnan Metallurgical Group Co., Ltd., competes with us in the business segments of alumina and primary aluminum, Chinalco, as the indirect controlling shareholder of Yunnan Aluminum and our direct controlling shareholder, issued a letter of undertakings on non-competition to us, according to which Chinalco undertook to start in 2019 planning the integration of the businesses in which Yunnan Aluminum and we compete with each other, and address such business competition within five years. For further details, please see “Item 4. Information on the Company – A. History and Development of the Company.” While we intend to closely monitor Chinalco’s planning and implementation of such business integration and make timely public disclosure about significant progress made, due to the uncertainties involved in such business integration, however, we cannot assure you that business competition between Yunnan Aluminum and us would be addressed without undue delays or at all, or the plan of such business integration or the implementation thereof would be viewed by you or other investors as most favorable to us or our shareholders.

We are subject to, and incur costs to comply with, environmental laws and regulations.

As we produce air emissions, discharge waste water, and handle hazardous substances at our bauxite mines, alumina refineries and primary aluminum smelters, we are subject to, and incur costs to comply with, environmental laws and regulations.

Given the magnitude, complexity and continuous amendments to these laws and regulations, compliance therewith may be onerous or may involve substantial financial and other resources to establish efficient compliance and monitoring systems. The liabilities, costs, obligations and requirements associated with these laws and regulations may therefore be substantial and may delay the commencement of, or cause interruptions to, our operations. Non-compliance with the relevant laws and regulations applicable to our operations may even result in substantial penalties or fines, suspension or revocation of our relevant licenses or permits, termination of government contracts or suspension of our operations. For example, relevant supervision authorities released a public notification of the dust, noise, relocation and other issues of Baotou Aluminum in 2020. In response to this notification, the Company and Baotou Aluminum attached great importance to the issues involved, analyzed the issues, and communicated with local governments and local residents proactively. As of the end of 2020, a majority of the issues involved have been rectified, dust and noise pollution have been effectively controlled, and the relocation of residents has been progressing smoothly under the organization of the local government. In 2021, Baotou Aluminum completed the project of “transformation from shipment by truck to shipment by rail,” established relevant facilities to reduce the dust and noise and engaged expert to analyze status of environmental governance and protection. However, as the environmental protection standards and requirements may be further enhanced, we cannot assure you that the similar events would not occur in the future, if such incidents were to occur, it could impact our operating results, financial condition and reputation, all of which could adversely affect our profitability and ability to retain existing customers and to attract new customers.

In addition, the environmental laws and regulations in the PRC and other jurisdictions in which we operate continue to evolve. As a result, we may incur significant additional costs if relevant laws and regulations change or enforcement of existing laws and regulations becomes more rigorous. For instance, in April 2020, the Law on Prevention and Control of Environmental Pollution Caused by Solid Waste was amended to impose stricter liabilities on enterprises that produce solid waste. The National Catalogue of Hazardous Wastes was also amended and the new version became effective on January 1, 2021, which detailed and reclassified some hazardous wastes. As we generate solid waste during our production process, we may incur higher costs to comply with the requirements under the amended law. Since 2017, the PRC government has carried out regulations and comprehensive campaigns to control air pollution in response to the poor air quality in autumn and winter in Beijing, Tianjin, Hebei and their surrounding areas and the Fenhe and Weihe plain, pursuant to which we may reduce output of our relevant plants from time to time. Further, our overseas expansion projects are subject to foreign environmental laws and regulations. Failure to comply with environmental laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of monetary penalties, the imposition of remedial requirements and the issuance of orders enjoining future operations, all of which may materially and adversely affect our business operations.

We are subject to administrative policies and orders relating to China’s energy-saving and emission reduction requirements that could adversely affect our production.

We are subject to administrative energy-saving and emission reduction policies and orders carried out by the central and provincial governments. The MIIT issued the Standard Conditions for Aluminum Industry on July 18, 2013 and updated it on February 28, 2020, which set forth various standards for existing enterprises, including but not limited to standards for environmental protection, energy consumption, and utilization of resources. We cannot assure you that the relevant government authorities will not issue more stringent standards or rules, which may require us to incur additional costs or expenses to comply with these standards or rules, and our existing production may be delayed for facility upgrading or suspended before full compliance with these standards or rules. The occurrence of any of the foregoing could have an adverse effect on our business, results of operations and financial condition.

We are subject to accidents and natural disasters that may adversely affect our performance.

We may experience accidents and natural disasters in the course of our operations, which may cause significant property damage and personal injuries. Significant accidents and natural disasters may cause interruptions to our operations or result in property or environmental damage, increase in operating expenses or loss of revenues. The occurrence of accidents, natural disasters and the resulting consequences may not be covered adequately, or at all, by the insurance policies we carry. Losses or payments incurred by us as a result of major accidents or natural disasters may have a material adverse effect on our results of operations.

13

We have not obtained valid titles or land use rights to certain properties or land parcels that we occupy.

We have not obtained valid ownership certificates to certain properties that we occupy. These properties are used primarily for production plants and daily operations management. As of December 31, 2021, the book value of our properties with defective titles is RMB6,609.2 million, which represents approximately 3.4% of our total asset value. In addition, we had not obtained land use rights to certain land parcels, which we use primarily for our production plants. As of December 31, 2021, the book value of these land parcels is RMB734.4 million, representing approximately 0.4% of our total asset value. We have applied to the appropriate authorities to obtain the relevant ownership certificates. We cannot give any assurance that ownership dispute will not occur or that third parties will not assert any claims against us for compensation in respect of any use of these properties or land parcels.

Our business involves inherent risks and occupational hazards, which could damage our reputation, subject us to liability claims and cause substantial costs to us.

Our business involves inherent risks and occupational hazards. Under our mining operations, we engage or may engage in certain inherently risky and hazardous activities, including, among others, operations at height or on dangerous terrains, underground excavation and construction, use of heavy machinery, mining and handling of flammable and explosive materials, and we are therefore subject to risks associated with these activities, including, among others, geological catastrophes, toxic gas and liquid leakages, equipment failures, industrial accidents, fire, explosions and underground water leakages. Although we conduct geological assessments on mining conditions and adapt our mining plans to the mining conditions at each mine, we cannot assure you that adverse mining conditions will not endanger our workforce, increase our production costs, reduce our bauxite or coal output or temporarily suspend our operations. The occurrence of any of the foregoing events or conditions could have a material adverse impact on our business and results of operations. Additionally, we are exposed to operational risks associated with industrial or engineering activities, such as maintenance problems or equipment failures. These risks and hazards may result in personal injury and fatal casualties, damage to or destruction of properties or production facilities, and pollution and other environmental damage. Any of these consequences, to the extent they are significant, could result in business interruption, possible legal liability and damage to our business reputation and corporate image.

Our mines and operating facilities may be damaged by water, gas, fire or cave-ins due to unstable geological structures. Any significant accident, business disruption or safety incident could result in substantial uninsured costs and the diversion of our resources, which could materially and adversely affect our business operations and financial condition.

We may be subject to product liability claims.

Some of the products we sell or manufacture may expose us to product liability claims relating to property damage or personal injury. The successful assertion of product liability claims against us could result in significant damage payments and harm to our reputation, which in turn could have a material adverse effect on our business, financial condition and results of operations.

We are subject to litigation risks.

In the ordinary course of business, claims involving project owners, customers, suppliers and subcontractors may be brought against us and by us in connection with our operations. If we were found to be liable on any of the claims, we would have to incur a charge against earnings to the extent a reserve had not been established for the matter in our accounts, or to the extent the claims were not sufficiently covered by our insurance coverage. Both claims brought against us and by us, if not resolved through negotiations, are often subject to lengthy and expensive litigation or arbitration proceedings, and claims against us may also result in freeze of or restrictions on our bank deposits or other assets during such lengthy legal proceedings. Charges associated with claims brought against us and write-downs associated with claims brought by us could have a material adverse impact on our business, financial condition, results of operations and cash flow. Moreover, legal proceedings resulting in judgments or findings against us may harm our reputation and damage our prospects for future contract or business awards.

14

We face counterparty risks.

While we generally sell goods and provide services to reputable customers and evaluate the customers’ credit in accordance with our internal risk management criteria, such as their credit history and likelihood of default, we have limited access to information about our customers, and we may encounter difficulties in the collection of receivables in certain countries that we have less experience in our dealings. Therefore, we cannot guarantee that all of our customers will fully perform their obligations under their respective contracts with us, and the deterioration of any customers’ credit or payment conditions may result in those customers defaulting on their contractual obligations, which could materially and adversely affect our business, financial condition and results of operations. In addition, disputes with governmental entities and other public organizations could potentially lead to contract termination if these remain unresolved or it may take a considerably longer period of time to resolve the disputes with counterparties in the private sector, and payments from these entities and organizations may be delayed as a result.

We face risks related to our derivative instruments.

From time to time, we may utilize derivative instruments to minimize our exposure to fluctuations in the price of primary aluminum and other products. We primarily use futures contracts and option contracts traded on the SHFE and LME to hedge against fluctuations in the price of primary aluminum. All of our future contracts and option contracts are held for hedging purpose. As of December 31, 2021, the fair value of the outstanding futures and option contracts recognized in financial assets and financial liabilities amounted to nil and RMB69 million, respectively. In the process of hedging with futures and options, we cannot assure you that we will not incur any loss, which may have an adverse effect on our financial condition and results of operations.

We may face challenges to our intellectual property rights which could adversely affect our reputation, business and financial position.

We own important intellectual property, including patents and trademarks. Our intellectual property plays an important role in maintaining our competitive position in a number of the markets that we serve. Our competitors may develop technologies that are similar or superior to our proprietary technologies or design around the patents we own or license. Developments or assertions by or against us relating to intellectual property rights, and any inability to protect or enforce these rights, could adversely affect our business and competitive position.

We may be exposed to claims in relation to the unsatisfactory performance of third-party service providers, and disputes with business partners may also adversely affect our business.

We rely on third-party service providers for certain services, including but not limited to mining infrastructure construction, logistics services or warehouse management. Therefore, we are exposed to the risk that our third-party service providers may fail to perform their obligations, which may adversely affect our business operations. In addition, from time to time, we cooperate with business partners to develop our business, including acquiring strategic mining resources or businesses that complement our own business line. Furthermore, we operate certain projects through joint venture arrangements and may enter into further joint ventures in the future along with the expansion of our operations. We may have disputes with these business partners or joint venture partners over various aspects, such as performance of each party’s obligations, scope of each party’s responsibilities, product quality and logistics services. If such disputes cannot be settled in a timely manner, our financial condition and business may be adversely affected.

Failure to hire and retain management executives and other qualified personnel could adversely affect our business and prospects.

The growth of our business operations depends on the continued services of our senior management team. The industry experience, expertise and contributions of our executives and other members of our senior management are essential to our continued success. We will require an increasing number of experienced and competent executives in the future to implement our growth plans. If we were to lose the services of any of our key management members and were unable to recruit and retain personnel with equivalent qualifications at any time, the management and growth of our business could be adversely affected.

Competition for qualified personnel in general is intense in the PRC and other markets where we operate. We cannot guarantee that we will be able to maintain an adequately skilled labor force necessary for us to execute our projects or to perform other corporate activities, nor can we guarantee that staff costs will not increase as a result of a shortage in the supply of skilled personnel. If we fail to attract and retain personnel with suitable managerial, technical or marketing expertise or maintain an adequate labor force on a continuous basis, our business operations could be adversely affected and our future growth and expansions may be inhibited.

15

We may not be able to detect and prevent fraud or other misconduct committed by our employees, representatives, agents, customers, affiliates or other third parties.

We may be exposed to fraud or other misconduct committed by our employees, representatives, agents, customers, affiliates or other third parties that could subject us to litigation, financial losses and sanctions imposed by governmental authorities, as well as adversely affect our reputation, business, financial condition, results of operations and ADS trading prices. Such misconduct may include, among others:

● hiding unauthorized or unsuccessful activities, resulting in unknown and unmanaged risks or losses;

● intentionally concealing material facts, or failing to adequately perform necessary due diligence or risk analysis procedures designed to identify potential risks;

● improperly using or disclosing confidential information;

● engaging in improper activities or activities that might be subject to penalties, fines or sanctions;

● misappropriation of funds;

● conducting transactions that exceed authorized limits;

● engaging in misrepresentation or fraudulent, deceptive or otherwise improper or illegal activities;

● engaging in unauthorized or excessive transactions to the detriment of our customers; or

● otherwise not complying with applicable laws or our internal policies and procedures.

Our internal control procedures are designed to monitor our operations and ensure overall compliance. However, such internal control procedures may be unable to identify, detect or prevent all incidents of non-compliance or suspicious transactions in a timely manner, if at all. In addition, we do not have control over the activities conducted on their own by those of our customers, affiliates or other third parties.

There is no assurance that fraud or other misconduct by our employees, representatives, agents, customers, affiliates or other third parties will not occur in the future. If such fraud or other misconduct does occur and to the extent that our employees, representatives, agents, customers, affiliates or other third parties are penalized for any of their non-compliance activities or are otherwise subject to any sanctions laws of foreign jurisdictions, it may cause negative publicity of us as a result, and could have a material adverse effect on our business, financial condition, results of operations and our ADS trading prices.

Cyber attacks and security breaches may threaten the integrity of our intellectual property and other sensitive information and disrupt our business operations, which could adversely affect our reputation, business and financial position.

We face global cybersecurity threats, which may range from uncoordinated individual attempts to sophisticated and targeted measures directed at us. Cyber attacks and security breaches may include, but are not limited to, attempts to access information, computer viruses, denial of service and other electronic security breaches. Cyber attacks and security breaches may cause equipment failures, loss of information and limited access to systems. For manufacturing companies, cyber attacks and security breaches may result in the theft of sensitive data, including valuable technical and marketing information, disruptions to operations and breakdown of industrial control system. The economic costs to us to eliminate or alleviate cyber attacks and security breaches could be significant and may be difficult to estimate or calculate because the loss may differ based on the identity and motive of the programmer or hacker, which are often difficult to identify. Further, the perpetrators of cyber attacks and security breaches are not restricted to specific groups or persons. These attacks may be committed by company employees or external actors operating in any geography, including jurisdictions where law enforcement measures to address such attacks are unavailable or ineffective, and may even be launched by or at the behest of nation states. In addition, new and amended PRC regulatory requirements regarding network security and information protection have been adopted in recent years to further strengthen the regulation in those areas. In 2021, both Data Security Law and Personal Information Protection Law were promulgated and became effective. We may be required to devote significant resources to establishing and maintaining our compliance with such new or amended legislation or regulations.

16

Although we have not experienced any material cybersecurity incidents in the past, we cannot assure you that we will not experience them in the future. Due to the evolving nature of cybersecurity threats, the scope and impact of any future incident cannot be predicted. While we devote significant resources to security measures to safeguard our systems and mitigate potential risks, such as deploying network protection devices and performing regular security assessment, there is no assurance that such actions will be sufficient to prevent cyber attacks or security breaches that manipulate or improperly use our systems or networks, compromise confidential or otherwise protected information, destroy or corrupt data, or otherwise disrupt our operations. The occurrence of such events could negatively impact our reputation and our competitive position and could result in litigation with third parties, regulatory action, loss of business, potential liability and increased remediation costs, any of which could have an adverse effect on our financial condition and results of operations.

We are subject to risks normally associated with cross-border transactions, and our export products may become subject to anti-dumping or countervailing duty proceedings.

During the past few years, we generated marginal revenue from exports of certain chemical alumina products and aluminum fabrication products and also from time to time from exports of certain non-ferrous metals and minerals products to foreign jurisdictions. In 2021, we only engaged in the export of certain chemical alumina products and aluminum fabrication products to foreign countries including, among others, South Korea, Japan and countries in Southeast Asia and revenue generated from such export accounted for approximately 4.8% of our total revenues in 2021. Such foreign jurisdictions and other countries may take restrictive measures, including, among others, imposition of tariffs, anti-dumping duties and other non-tariff barriers, to protect their own markets. The sales of our product in overseas markets may be adversely affected by increases in or new impositions of anti-dumping duties, countervailing duties, quotas or tariffs imposed on our exports. Further increases in or new imposition of anti-dumping duties, countervailing duties, quotas or tariffs on our sales in these markets could adversely affect the exports to these regions in the future. For example, since 2018, the U.S. government has imposed tariffs and other trade barriers on products imported from China, which elicited retaliatory tariff increases by the PRC government on the U.S. products. Since October 1, 2018, the U.S. government had imposed a 10% tariff on various aluminum products imported from China, including chemical alumina products. Starting from May 2019, this tariff rate was increased to 25%. In 2021, we exported approximately 24,000 tonnes of chemical alumina products to the United States, the revenue generated from which represented approximately 0.04% of our total revenues in 2021. Other than exports of chemical alumina products, we did not have any other exports to the United States in 2021. There is no assurance that such export volume of chemical alumina products will not further decrease in the future. In addition, such trade frictions and tariffs involved may decrease China’s aluminum export to the United States and other countries and reduce global aluminum consumption, which could in turn have a material adverse effect on the demand of our products as well as our business, financial condition and results of operations. On January 15, 2020, the PRC government and the U.S. government entered into the U.S.-China Phase One trade deal agreement. Since then, the PRC government and the U.S. government have granted tariff exemptions on certain goods. However, it is not yet clear what further actions the U.S. government and the PRC government may take. There is no assurance that a broader trade agreement would be successfully negotiated between the U.S. and China, or no additional tariffs or other trade barriers would be imposed. If there is any escalation in trade frictions, we cannot assure you whether such development would not have a material adverse effect on the business environment in general, global economic conditions and the stability of global financial markets. Any of these factors affected by the developments in trade barriers could in turn have a material adverse effect on our business, financial condition and results of operations.

By virtue of our transactions with parties outside the PRC, we will be subject to the risks normally associated with cross-border business transactions and activities. We will also be exposed to the risk of changes in social, legal, political and economic conditions in the foreign jurisdictions. In particular, unexpected changes in regulatory requirements, tariffs and other trade barriers and price or exchange controls could limit our operations and make the repatriation of profits difficult.

Our operations are affected by a number of risks relating to conducting business in the PRC.

As most of our assets and operations are located in the PRC, we are subject to a number of risks relating to conducting business in the PRC, including the following:

● The PRC government continues to shape the structure and development of the aluminum industry through industry guidelines for energy conservation, safety, environmental protection and quality. The central and local PRC government will give more support to entities that meet the standards in such industry guidelines. If the PRC government changes its current industry guidelines or the interpretation of those industry guidelines, we may face pressure on profit margins and constraints on our ability to expand our business operations.

17

● Although the PRC has been one of the world’s fastest-growing economies in terms of GDP growth in the past 30 years, the global financial crisis that unfolded in 2008, coupled with the ongoing structural adjustment of the PRC economy in the past few years, has led to a marked slowdown in the economic growth of the PRC. For example, the GDP growth rate of the PRC decreased from 11.4% in 2007 to 6.1% in 2019. Furthermore, the outbreak and global spread of the COVID-19 in 2020 and 2021 has adversely affected global and China’s economy and financial market in general. As a result, the compound annual GDP growth rate of China was 5.1% in 2020 and 2021. Please refer to “– Our business may be materially and adversely affected by the COVID-19 pandemic” for further details of the impact of the outbreak of COVID-19. A slowdown or decline in the PRC economy could reduce business activities and demand for our products. In addition, the PRC government exercises control over China’s economic growth through the allocation of resources, control of payments of obligations denominated in foreign currencies and monetary and tax policies. Some of these measures benefit the overall economy of China, but may have a materially adverse impact on us.

● We are subject to reviews and inspections by various governmental authorities and regulatory agencies. These reviews and inspections could cover a broad range of aspects in relation to our business and operations, including financial reporting, tax reporting, internal control and compliance with applicable laws, rules and regulations. We cannot predict the impact of any findings of these reviews and inspections to be carried out by governmental authorities and regulatory agencies in the future, and we cannot assure you that the outcome of any such reviews and inspections would not have a material adverse effect on our business, financial condition, results of operations and prospects.

● In 2005, China adopted a managed floating exchange rate system to allow the value of the Renminbi to fluctuate within a regulated band based on supply and demand with reference to a basket of currencies. Since then the exchange rate between the U.S. dollar and Renminbi has fluctuated and become increasingly unpredictable following the global financial crisis in 2008. In April 2012, the PRC government took a milestone step in turning the Renminbi into a global currency by doubling the size of its trading band against the U.S. dollar to 1%, pushing through a crucial reform that further liberalizes its financial markets. The PBOC further allows the Renminbi trading band against the U.S. dollar to rise or fall 2% from a mid-point every day, effective on March 17, 2014, compared with its previous 1% limit. In August 2015, the PBOC announced that the daily central parity quotes the market-makers reported to the China Foreign Exchange Trade System operated by the PBOC before the market opens should be based on the closing rate of the inter-bank foreign exchange rate market on the previous day, supply and demand in the market, and price movement of major currencies, effective on August 11, 2015. In recent years, the Renminbi has fluctuated against the U.S. dollar, at times significantly. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future. Any appreciation or depreciation of the Renminbi will affect the value of our U.S. dollar-denominated borrowings and overseas investments, the prices of our export sales denominated in foreign currencies and the Renminbi equivalent value of our trade and notes receivable denominated in foreign currencies, which may affect our financial condition and results of operations. Our financial condition and operating performance may also be affected by changes in the value of currencies other than Renminbi in which our earnings and obligations are denominated.

● There might be uncertainties regarding the interpretation and enforcement of PRC laws, rules and regulations. The Chinese legal system is a civil law system based on written statutes. Unlike common law systems, it is a system in which decided legal cases may be cited for reference but have limited precedential value. Over the past decades, the PRC government has promulgated a comprehensive system of laws, rules and regulations governing economic matters. However, because these laws, rules and regulations are relatively new, and because of the relatively limited volume of published cases and their non-binding nature, and because the laws, rules and regulations often give the relevant administrative and court authorities certain discretion in how to interpret and enforce them, uncertainties regarding the interpretation and enforcement of these laws, rules and regulations may adversely affect our operations.

You may experience difficulties in effecting service of legal process and enforcing judgments against us and our management, and the ability of U.S. authorities to bring actions in the PRC may also be limited.

Most of our assets and our subsidiaries are located in the PRC. In addition, most of our directors and officers reside within the PRC, and most of the assets of our directors and officers are located within the PRC. As a result, it may not be possible to effect service of process within the United States or elsewhere outside the PRC upon most of our directors or officers, including with respect to matters arising under applicable laws and regulations. Moreover, the PRC does not have treaties providing for the reciprocal recognition and enforcement of judgments of courts with the United States, the United Kingdom or most other Western countries, and Hong Kong has no arrangement for the reciprocal enforcement of judgments with the United States.

18

As a result, recognition and enforcement in the PRC or Hong Kong of judgments of a court in the United States and any of the other jurisdictions mentioned above in relation to any matter not subject to a binding arbitration provision may be difficult or impossible. Even if you sue successfully in a U.S. court or any of the other jurisdictions mentioned above, you may not be able to collect on such judgment against us or our directors and officers. In addition, the SEC, the U.S. Department of Justice and other U.S. authorities may also have difficulties in bringing and enforcing actions against us or our directors or officers in the PRC. Furthermore, class action lawsuits, which are available in the United States for investors to seek remedies, are generally uncommon in the PRC.

The audit reports included in this annual report are prepared by auditors who are not inspected by the Public Company Accounting Oversight Board and, as such, you are deprived of the benefits of such inspection.

Auditors of companies that are registered with the SEC and traded publicly in the United States, including our independent registered public accounting firms, must be registered with the U.S. Public Company Accounting Oversight Board (United States) (the “PCAOB”) and are required by the laws of the United States to undergo regular inspections by the PCAOB to assess their compliance with the laws of the United States and professional standards. Because we have substantial operations within the PRC and the PCAOB is currently unable to conduct full inspections of the work of our auditors as they relate to those operations without the approval of the Chinese authorities, our auditors’ work related to our operations in China is not currently inspected by the PCAOB.

This lack of PCAOB inspections of audit work performed in China prevents the PCAOB from regularly evaluating audit work of any auditor that was performed in China including that performed by our auditors. As a result, investors are deprived of the full benefits of PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our independent registered public accounting firm’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to the PCAOB inspections, which could cause our investors and potential investors to lose confidence in our audit procedures and reported financial information and the quality of our financial statements.

Our ADSs will be delisted under the Holding Foreign Companies Accountable Act if the PCAOB is unable to inspect auditors who are located in China. In addition, legislative and regulatory developments related to U.S.-listed China-based companies due to lack of PCAOB inspection and other developments may have a material adverse impact on our listing and trading in the United States and the trading prices of our ADSs. The potential delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.

As part of continued regulatory focus in the United States on access to audit and other information currently protected by foreign law, in particular the PRC’s law, on December 18, 2020, the United States enacted the Holding Foreign Companies Accountable Act, or the HFCA Act. The HFCA Act includes requirements for the SEC to identify issuers whose audit reports are prepared by auditors that the PCAOB is unable to inspect or investigate completely because of a restriction imposed by a non-U.S. authority in the auditor’s local jurisdiction. The HFCA Act also requires public companies on this SEC list to certify that they are not owned or controlled by a foreign government and make certain additional disclosure in their SEC filings that cover a “non-inspection” year after the HFCA Act becomes effective. In addition, if the auditor of a U.S.-listed company is not subject to PCAOB inspections for three consecutive “non-inspection” years after the law becomes effective, the SEC is required to prohibit the securities of these issuers from being traded on a U.S. national securities exchange, such as the New York Stock Exchange, on OTC markets in the United States or through any other method within the SEC’s jurisdiction to regulate.

On September 22, 2021, the PCAOB adopted a final rule implementing the HFCA Act, which provides a framework for the PCAOB to determine, as contemplated under the HFCA Act, whether the PCAOB is unable to inspect or investigate completely registered public accounting firms located in a foreign jurisdiction because of a position taken by one or more authorities in that jurisdiction. Final rules implementing certain requirements of the HFCA Act, or the Final Rules, were adopted by the SEC on December 2, 2021 and generally became effective on January 10, 2022. The Final Rules implement the submission and disclosure requirements in the HFCA Act, which apply to registrants the SEC identifies as having filed an annual report with an audit report issued by a registered public accounting firm that is located in a foreign jurisdiction and that the PCAOB is unable to inspect or investigate, or Commission-Identified Issuers. The Final Rules require Commission-Identified Issuers to submit documentation to the SEC establishing that, if true, it is not owned or controlled by a governmental entity in the public accounting firm’s foreign jurisdiction. The Final Rules also require that a Commission-Identified Issuer that is a “foreign issuer” provide certain additional disclosures in its annual reports. Specifically, Item 16I (Disclosure Regarding Foreign Jurisdictions that Prevent Inspections) has been added in Form 20-F, which requires disclosure in a foreign issuer’s annual report regarding the audit arrangements of, and governmental influence on, such foreign issuer. Further, the Final Rules established procedures the SEC will follow to identify issuers and to impose trading prohibitions on the securities of certain Commission-Identified Issuers, as required by the HFCA Act. On December 16, 2021, the PCAOB issued the HFCA Act Determination Report, according to which our auditor is subject to the determination that the PCAOB is unable to inspect or investigate it completely.

19

Under the Final Rules, the SEC will identify Commission-Identified Issuers for fiscal years beginning after December 18, 2020. As of the date of this annual report, the SEC has named six PRC-based issuers on its “conclusive list of issuers identified under the HFCA Act,” indicating that those companies are now Commission-Identified Issuers subject to the delisting provisions if they remain on the list for three consecutive years. In addition, the SEC has named 17 PRC-based issuers on its “provisional list of issuers identified under the HFCA Act.” Issuers provisionally identified have 15 business days to submit evidence to dispute being provisionally identified as a Commission-Identified Issuer. We anticipate being added to the list shortly after the filing of this annual report on Form 20-F for the fiscal year ended December 31, 2021. A Commission-Identified Issuer will be required to comply with the submission and disclosure requirements in the annual report for each year in which it was identified. When we are identified as a Commission-Identified Issuer based on this annual report, we will be required to comply with the submission or disclosure requirements in our annual report filing covering the fiscal year ending December 31, 2022. Under the HFCA Act and the Final Rules, our securities will be prohibited from trading on the NYSE and in over-the-counter markets after we are identified as a Commission-Identified Issuer for three consecutive years, and this ultimately would result in our ADSs being delisted from the NYSE and prohibited from over-the-counter trading after we file our annual report for the fiscal year ending December 31, 2023 in 2024.

Furthermore, on June 22, 2021, the U.S. Senate passed the Accelerating Holding Foreign Companies Accountable Act, which, if enacted, would amend the HFCA Act and require the SEC to prohibit an issuer’s securities from trading on any U.S. stock exchanges if its auditor is not subject to PCAOB inspections for two consecutive years instead of three years (the “Accelerating Amendments”). On February 4, 2022, the U.S. House of Representatives passed the America Creating Opportunities for Manufacturing, Pre-Eminence in Technology and Economic Strength Act, or America COMPETES Act, which includes the exactly same Accelerating Amendments. The America COMPETES Act however includes a broader range of legislation not related to the HFCA Act in response to the U.S. Innovation and Competition Act passed by the Senate in 2021. On March 28, the U.S. Senate voted on an amended version that substituted America COMPETES Act with the text of the U.S. Innovation and Competition Act, which does not include the Accelerating Amendments. The U.S. House of Representatives and Senate will need to align the legislation and pass their amended bill before the President can sign it into law. It is unclear when the U.S. Senate and House of Representatives will resolve the differences in the U.S. Innovation and Competition Act and the America COMPETES Act bills, or whether the final bill agreed by the U.S. Senate and House of Representatives will include the Accelerating Amendments. In the case that the bill containing the Accelerating Amendments becomes the law, our ADSs would be delisted from the NYSE and prohibited from over-the-counter trading in the U.S. after we file our annual report for the fiscal year ending December 31, 2022 in 2023.

We understand that there have been dialogues among the CSRC, the SEC and the PCAOB regarding the inspection of PCAOB-registered accounting firms in China. Furthermore, on April 2, 2022, PRC government issued the “Provisions on Strengthening Confidentiality and Archives Administration in Overseas Issuance and Listing of Securities by Domestic Enterprises (Draft for Comment)”, which deleted the old requirement that “on-site inspections should be mainly conducted by PRC regulatory authorities, or rely on the inspection results of PRC regulatory authorities”, but still required, among others, that inspection and evidence collection should be conducted by way of cross-border regulatory cooperation. There can be no assurance that PRC regulatory authorities will reach a regulatory cooperation agreement with the SEC and the PCAOB, or our auditor or we will be able to comply with requirements imposed by the U.S. regulators.

The delisting of our ADSs would substantially impair your ability to sell or purchase our ADSs when you wish to do so, and the risk and uncertainty associated with delisting would have a negative impact on the price of our ADSs. Also, such a delisting would adversely affect our ability to raise capital on terms acceptable to us, or at all, which would have a material adverse impact on our business, financial condition, and prospects. Holders of our ADSs may convert the ADSs into our H shares listed on the Hong Kong Stock Exchange but will incur costs in order to do so. See “Item 12. Description of Securities Other than Equity Securities” for further information. The value and liquidity of our ADSs may therefore be materially and adversely affected.

Private Placement of A Shares

On March 8, 2012, our Board resolved to issue up to 1.25 billion A Shares in the PRC. The A Share issue plans previously proposed by our Board on June 30, 2009 and January 30, 2011 and approved by our shareholders at the extraordinary general meeting, A Share class meeting and H Share class meeting held on August 24, 2009 and on April 14, 2011, respectively, ceased. Pursuant to the new issue plan approved by our Board on March 8, 2012, we planned to issue up to 1.25 billion A Shares, with a nominal value of RMB1.00 each, by way of private placement for expected proceeds not exceeding RMB8 billion. We intended to issue the A Shares to no more than ten specific target subscribers within six months of obtaining the approval of the CSRC. The issue price of A Shares to be offered shall be not less than 90% of the average trading price of our A Shares in 20 trading days immediately preceding the pricing determination date. We intended to apply proceeds from this private placement to finance Chalco Xing County Alumina Project, Zhongzhou branch Ore-dressing Bayer Process expansion construction project and to supplement working capital. The issue plan was approved by the SASAC on April 5, 2012 and by our shareholders at the extraordinary general meeting, A Share class meeting and H Share class meeting held on May 4, 2012. On August 24, 2012, our Board resolved to adjust the issue plan by proposing, among others, to increase the number of A Shares to be issued to up to 1.45 billion A Shares. The adjusted issue plan was approved by the SASAC and our shareholders at an extraordinary general meeting, A Share class meeting and the H Share class meeting on October 12, 2012 and by the CSRC on December 7, 2012. On March 14, 2013, we obtained the approval from the CSRC on our proposed private placement of A Shares under such adjusted issue plan, with effective period of six months after the approval date. However, the CSRC temporarily retrieved its approval in July 2013 due to its ongoing investigation of the sponsor of our proposed private placement of A Shares. The period of authorization to the Board relating to the adjusted issue plan was extended by our shareholders at the 2013 annual general meeting, A Share class meeting held on June 27, 2014 and H Share class meeting held on June 27, 2014, with an effective period of 12 months after the approval date. On January 4, 2015, we submitted the “Report regarding the resumption of the approval of non-public offering of shares of Aluminum Corporation of China Limited” to the CSRC. On April 24, 2015, we received the Approval in Relation to the Non-public Issuance of Shares by Aluminum Corporation of China Limited issued by the CSRC, pursuant to which we were approved to issue no more than 1,450,000,000 new shares. We completed the non-public issuance of A Shares on June 15, 2015 and issued an additional 1,379,310,344 A Shares pursuant to the specific mandate as approved at the annual general meeting of the Company on June 27, 2014. Upon completion, the total number of A Shares of the Company was increased from 13,524,487,892 to 14,903,798,236. Please refer to “– Subscription of Equity Interest of Certain Subsidiaries and Subsequent Issuance of Additional A Shares” for further changes of our issuance of A Shares.

Disposal of Aluminum Fabrication Business

We disposed of substantially all of our aluminum fabrication operations to Chinalco pursuant to the approval of shareholders at the 2012 annual general meeting on June 27, 2013.

On May 13, 2013, we submitted the tender notice to CBEX to dispose of the equity interest we held in eight aluminum fabrication enterprises, including Henan Aluminum, Chalco Southwest Aluminum, Chalco Southwest Aluminum Cold Rolling, Huaxi Aluminum, Qingdao Light Metal, Chalco Ruimin, Chalco Sapa Aluminum Products (Chongqing) Co., Ltd. and Guizhou Chalco Aluminum Co., Ltd. (collectively, “Aluminum Fabrication Interests”) through open tender. Chinalco participated in and won the bid for the Aluminum Fabrication Interests on June 7, 2013. We entered into an agreement (the “Aluminum Fabrication Interests Transfer Agreement”) with Chinalco on June 9, 2013 for the disposal of Aluminum Fabrication Interests for a consideration of RMB3,242.2 million. Such consideration was the initial bidding price, which was determined with reference to the appraised value of the Aluminum Fabrication Interests. Pursuant to the Aluminum Fabrication Interests Transfer Agreement, Chinalco agreed to pay the consideration in cash in two installments, namely, 30% of the consideration to be paid within five business days after the effective date of the agreement and 70% of the consideration to be paid by June 30, 2014. Chinalco must pay interest for the second installment for the period starting from the date immediately after the effective date until the payment date at the one-year lending rate set by the PBOC. The disposal was approved at the 2012 annual general meeting held on June 27, 2013 and we completed the disposal on June 27, 2013. Chinalco paid the consideration in full by June 2014.

As a condition of the disposal of the Aluminum Fabrication Interests, on June 9, 2013, we entered into an agreement with Chinalco to transfer the outstanding entrusted loans we provided to Henan Aluminum and Qingdao Light Metal as of December 31, 2012 to Chinalco for a consideration of RMB1,756.0 million. Such consideration was determined based on negotiations between the parties, with reference to the appraised total value of the loans. Pursuant to the agreement, Chinalco agreed to pay the consideration in cash in five equal installments of RMB351.2 million, with the last installment, together with the relevant interests at the one-year lending rate set by the PBOC, to be paid by June 30, 2017. The transfer was approved at the 2012 annual general meeting held on June 27, 2013 and we completed the transfer on June 27, 2013. The payment was fully settled by Chinalco in accordance with the agreement.

In addition, we entered into an agreement with Northwest Aluminum Fabrication Plant, a subsidiary of Chinalco, on June 6, 2013 to dispose of all the assets of Northwest Aluminum for RMB1,659.6 million. Such consideration was determined based on negotiations between the parties, with reference to the appraised net asset value of Northwest Aluminum. Pursuant to the agreement, Northwest Aluminum Fabrication Plant agreed to pay the consideration in cash in five equal installments of RMB331.9 million, with the last installment, together with the relevant interests at the one-year lending rate set by the PBOC, to be paid by June 30, 2017. The disposal was approved at the 2012 annual general meeting held on June 27, 2013 and we completed the disposal on June 27, 2013. The payment was fully settled by Northwest Aluminum Fabrication Plant in accordance with the agreement.

Disposal of Assets of Alumina Production Line of Guizhou Branch

On June 6, 2013, we entered into an agreement with Guizhou Aluminum Plant, a subsidiary of Chinalco, to dispose of the assets of the alumina production line of our Guizhou branch for a consideration of RMB4,429.0 million. Such consideration was determined based on negotiations between the parties, with reference to the appraised net asset value of such alumina assets of our Guizhou branch. Pursuant to the agreement, Guizhou Aluminum Plant agreed to pay the consideration in cash in five equal installments of RMB885.8 million, with the last installment, together with the relevant interests at the one-year lending rate set by the PBOC, to be paid by June 30, 2017. The disposal was approved at the 2012 annual general meeting held on June 27, 2013 and we completed the disposal on June 27, 2013. The payment was fully settled by Guizhou Aluminum Plant in accordance with the agreement.

We decided to dispose of the assets of the alumina production line of Guizhou branch because the district in which they were located had been changed from an industrial district to a commercial district based on the local urban plan, which would significantly increase Guizhou branch’s environmental compliance costs. We built a new alumina refinery, Guizhou Huajin, in an area relatively close to major bauxite and coal mines in Guizhou Province, which commenced production with an annual capacity of 1.6 million tonnes of alumina in 2015.

Transfer of Equity Interest in Shanxi Huaxing

The Chalco Xing County Alumina Project, which was carried out by Shanxi Huaxing, commenced construction in May 2011 and undertook full operation in 2014. After completion of private placement of A Shares in June 2015, the Board resolved to replace the funds which have been invested by us in advance with the proceeds raised from the private placement of A Shares. In light of our strategic blueprint for the development of Shanxi aluminum recycle industrial park, we planned to introduce strategic investors for joint investment and cooperation to develop a new model of integrated coal, electricity and aluminum operations. In December 2015, we entered into an equity transfer agreement with Shenzhen CR Yuanta Asset Management Co., Ltd., a state-owned entity, to transfer 50% equity interests in Shanxi Huaxing, a wholly-owned subsidiary, through the Shanghai United Assets and Equity Exchange at a price of RMB2,351 million (the “2015 Equity Transfer Agreement”). The price was determined based on the appraisal value provided by an independent qualified appraisal company. According to the 2015 Equity Transfer Agreement, 30% of the consideration amounting to RMB705 million has been received by us in December 2015. In December 2016, Shenzhen CR Yuanta Asset Management Co., Ltd. transferred the 50% of equity interest in Shanxi Huaxing to Baotou Transportation Investment Group Co., Ltd. As agreed among Shenzhen CR Yuanta Asset Management Co., Ltd., Baotou Transportation Investment Group Co., Ltd. and the Company, Baotou Transportation Investment Group Co., Ltd., shall assume the payment obligation on the outstanding consideration of RMB1,646,035,160 payable by Shenzhen CR Yuanta Asset Management Co., Ltd. to the Company under the 2015 Equity Transfer Agreement and settle the outstanding consideration in full together with interest accrued thereon from January 1, 2017 to the date of payment before March 31, 2017. The payment was fully settled by Baotou Transportation Investment Group Co., Ltd. in March 2017.

In December 2018, we entered into an equity transfer agreement with Baotou Transportation Investment Group Co., Ltd., pursuant to which we agreed to acquire 50% equity interest in Shanxi Huaxing through the Shanghai United Assets and Equity Exchange at a price of approximately RMB2,665.2 million, which we paid in full in December 2018. Upon completion of the acquisition, Shanxi Huaxing became a wholly-owned subsidiary of the Company. The acquisition is conducted for the purpose of enhancing our profitability and is in line with our strategic layout of alumina and aluminum business, as the increase of our shareholding in Shanxi Huaxing, an alumina plant, is expected to enhance the synergy with our primary aluminum production in Shanxi, where we have newly added production capacity of primary aluminum.

Transfer of Shares of Jiaozuo Wanfang

On January 22, 2015 and January 23, 2015, we decreased our shareholding in Jiaozuo Wanfang by 4,758,858 shares through the securities exchange system of the Shenzhen Stock Exchange. In March 2015, we transferred 100,000,000 shares of Jiaozuo Wanfang to Geo-Jade Petroleum Corporation by way of agreement after the public solicitation for potential transferees. On June 25, 2015, we further transferred 42,550,900 shares of Jiaozuo Wanfang by way of block trading through the securities exchange system of the Shenzhen Stock Exchange. On December 18, 21 and 22, 2015, we reduced our shareholding in Jiaozuo Wanfang by 16,695,100 shares through the centralized bidding trading system of the Shenzhen Stock Exchange. From December 23 to 25, 2015, we reduced our shareholding in Jiaozuo Wanfang by 13,865,000 shares through the centralized bidding trading system of the Shenzhen Stock Exchange and block trading. As a result, we held 29,582,057 shares of Jiaozuo Wanfang as of December 31, 2015, representing 2.46% of the total share capital of Jiaozuo Wanfang. During the period from July 8, 2016 to September 27, 2016, we reduced our shareholding of Jiaozuo Wanfang by an aggregate of 16,628,098 shares via the Shanghai Stock Exchange centralized bidding trading system, representing approximately 1.39% of the total share capital of Jiaozuo Wanfang. The average price of reduction was approximately RMB8.73 per share. After the reduction, the Company remained holding 12,953,959 shares of Jiaozuo Wanfang, representing approximately 1.09% of its total share capital. During the period from September 29, 2016 to January 26, 2017, we reduced our shareholding of Jiaozuo Wanfang by an aggregate of 12,953,959 shares via the Shanghai Stock Exchange centralized bidding trading system, representing approximately 1.09% of the total share capital of Jiaozuo Wanfang. The average price of reduction was approximately RMB10.19 per share. After such reduction in our shareholding, we no longer hold any shares of Jiaozuo Wanfang.

Disposal of Certain Assets of Guizhou Branch

Guizhou branch entered into a land reserve acquisition cooperation agreement with the People’s Government of the Baiyun District of Guiyang, Guiyang Land Reserve Center, and Guizhou Aluminum Plant on November 13, 2015. As the land of Guizhou Aluminum Plant occupied by the primary aluminum plant of Guizhou branch shall be transferred to the respective land resources and reserve authorities, Guizhou branch sold the relevant assets, including buildings and structures located on the land occupied by the primary aluminum plant of Guizhou branch, to the Guiyang Land Reserve Center for a total consideration of RMB1.95 billion. The consideration was determined based on the asset appraisal conducted by an independent asset appraisal firm.

Disposal of the Environmental Protection Business

On May 30, 2016, the Board approved the transfer of the environmental protection assets in relation to the desulfurization, denitration and dedusting of the coal-fired generating units of five entities, namely Lanzhou branch, Baotou Aluminum, Shandong Huayu, Maliantai Power Station and Liupanshan Power Station of Ningxia Energy, by way of public bidding. On June 29, 2016, the assets transfer agreement in relation to disposal of the above environmental protection assets were entered into between Beijing Aluminum SPC Environment Protection Tech Co., Ltd., which had won the bid for the acquisition of the assets, and us.

Subscription of Equity Interest of Certain Subsidiaries and Subsequent Issuance of Additional A Shares (“Asset Restructuring”)

On December 4, 2017, we entered into certain investment and debt conversion agreements (the “Initial Agreements”) with Huarong Ruitong Equity Investment Management Co., Ltd. (“Huarong Ruitong”), China Life Insurance Company Limited (“China Life”), Shenzhen Zhaoping Chalco Investment Center LLP (“Zhaoping Investment”), China Pacific Life Insurance Co., Ltd. (“CPIC Life”), China Cinda Asset Management Co., Ltd. (“China Cinda”), BOC Financial Asset Investment Co., Ltd. (“BOC Financial”), ICBC Financial Asset Investment Co., Ltd. (“ICBC Financial”) and ABC Financial Asset Investment Company Limited (“ABC Financial”) (collectively, the “Restructuring Investors”). Pursuant to the Initial Agreements, Huarong Ruitong, China Life, Zhaoping Investment, CPIC Life, BOC Financial, ICBC Financial and ABC Financial have agreed to make cash contributions to our wholly-owned subsidiaries, Chalco Shandong, Zhongzhou Aluminum, Baotou Aluminum and Chalco Mining (collectively, the “Target Subsidiaries”), while the principal of loans owed by Chalco Mining to Huarong Ruitong, Zhaoping Investment, China Cinda and BOC Financial prior to signing of the Initial Agreements would be treated as capital contribution to Chalco Mining and converted into equity interest in Chalco Mining held by Huarong Ruitong, Zhaoping Investment, China Cinda and BOC Financial. The Restructuring Investors have agreed to acquire 30.80%, 36.90%, 25.67% and 81.14% of equity interest of Chalco Shandong, Zhongzhou Aluminum, Baotou Aluminum and Chalco Mining, respectively, with an aggregate capital contribution of approximately RMB12.6 billion. Under the Initial Agreements, we have also agreed to acquire equity interest held by the Restructuring Investors in the Target Subsidiaries with consideration in the form of our A Shares to be issued to the Restructuring Investors. On December 20, 2017, the Initial Agreements and the transactions contemplated thereunder were approved at our 2017 second extraordinary general meeting. In December 2017, the capital contribution to the Target Subsidiaries by the Restructuring Investors was completed in accordance with the terms of the Initial Agreements.

26

Subsequently, on January 31, 2018, we entered into equity acquisition agreements (the “Further Agreements”) with the Restructuring Investors. Pursuant to the Further Agreements, we have agreed to acquire all the equity interest held by the Restructuring Investors in the Target Subsidiaries with consideration in the form of A Shares of the Company to be issued to the Restructuring Investors (the “Proposed Issuance”). The number of A Shares in issue pursuant to the Proposed Issuance would equal the appraised value of equity interest held by Restructuring Investors in Target Subsidiaries as of December 31, 2017 determined by China United Assets Appraisal divided by the issue price. The aforementioned appraised value might be subject to further adjustment by competent PRC authorities upon filing of the valuation report by China United Assets Appraisal. The issue price has been set at RMB6.00 per A Share with reference to 90% of the average trading price of our A Shares during the last 60 trading days prior to January 31, 2018 (i.e., the last 60 trading days prior to the suspension of trading of our A Shares) in accordance with rules and regulations of the PRC applicable to transaction of this kind. The appraised value, subject to further adjustment, was RMB12.7 billion and therefore we would issue to the Restructuring Investors approximately 2.1 billion A Shares in aggregate, representing approximately 14.2% of the total issued share capital of the Company as of January 31, 2018 and approximately 12.4% of the enlarged total issued share capital of the Company upon completion of the Proposed Issuance. On July 30, 2018, we entered supplemental equity acquisition agreements with the Restructuring Investors, amending, among others, the final consideration of the proposed acquisition and the number of the consideration shares to be issued from approximately RMB12,703.7 million and approximately 2,117,280,800 to approximately RMB12,713.2 million and 2,118,874,715, respectively. The Proposed Issuance was approved by our shareholders, the SASAC and the CSRC in 2018. In February 2019, all equity interests of Target Subsidiaries held by the Restructuring Investors were transferred to us, which resulted in us holding 100% equity interests of all Target Subsidiaries. On February 25, 2019, we issued an aggregate of 2,118,874,715 A Shares to the Restructuring Investors and our total share capital increased from 14,903,798,236 shares to 17,022,672,951 shares. The shares issued to the Restructuring Investors could be traded on the Shanghai Stock Exchange since February 26, 2020 after the expiry of the 12-month lock-up period.

Cash contributions received from the Restructuring Investors have been used by us for the repayment of loans. The Asset Restructuring has helped to reduce the gearing ratios of these subsidiaries and us as a whole.

Boffa Project

On June 8, 2018, Chalco Hong Kong and Chalco Guinea Company S.A., a wholly-owned subsidiary of Chalco Hong Kong, entered into a mining convention (the “Mining Convention”) with the Guinean government, pursuant to which Chalco Hong Kong agreed to provide investment funds while the Guinean government agreed to provide mining licenses and rights to transport mining products for the development and operation of the Boffa Project, a project for the construction and development of a bauxite mine located in Boffa, Guinea.

Based on our preliminary research and analysis and after taking into account various factors, including but not limited to (i) the bauxite reserve and the minable quantity in the mining area of the Boffa Project; (ii) the advancement and effectiveness of the existing development technologies; (iii) labor costs, transportation expenses and other development costs and other factors, the total investment of the Boffa Project is estimated to be approximately US$706 million, subject to adjustment pursuant to the actual needs, which will be mainly allocated in the construction of mines, ports and lightering system and is expected to be funded through capital investment together with shareholders’ loans or bank loans. According to our preliminary design plan, the total investment for the construction of mines is estimated to be approximately RMB3,088 million. The Boffa Project was completed and put into operation in April 2020. As of December 31, 2021, an aggregate of RMB2,821 million of capital expenditure had been incurred for the Boffa Project.

In accordance with the Mining Convention, a mining company (the “Mining Company”) and a port company (the “Port Company”) are established to act as the main operating bodies for mines construction and ports construction, respectively. In accordance with the Mining Convention, we own 85% and 95% equity interests in the Mining Company and the Port Company, respectively, while the Guinean government and its wholly-owned companies collectively own 15% and 5% equity interests in the Mining Company and the Port Company, respectively. Pursuant to the Mining Convention, Chalco Hong Kong shall grant the Guinean government and/or its wholly-owned companies an option to obtain additional equity interests in the Mining Company and grant Societe Guineenne de Patrimoine Minier, a company wholly-owned by the Guinean government, an option to obtain additional equity interests in the Port Company (together, the “Options”). If the Options are exercised in full, our equity interests in the Mining Company and Ports Company will reduce to 65% and 90%, respectively. As of December 31, 2021, the Options had not been exercised.

27

With a large reserve of resources, we believe the Boffa Project would provide sustainable bauxite resources for our alumina production and its high ore grades would help reduce alkali and energy consumption in our alumina production. In addition, as the mines are close to port, we are able to consolidate inland waterway transportation and maritime transportation, which benefits long-term development of the project and effectively controls investment risks at the early stage.

The Boffa Project commenced construction in September 2018 with an expected annual bauxite output capacity of 12 million tonnes. The project was completed and put into operation in April 2020. From then through the end of 2021, we extracted approximately 20.4 million tonnes of bauxite from the Boffa mine. The annual bauxite output capacity is expected to increase to 15 million tonnes in 2022.

Merger and Reorganization of Zunyi Alumina and Zunyi Aluminum

On June 21, 2018, in order to streamline our production chains, enhance synergistic effects and control operating costs, we entered into a contribution agreement with other shareholders of Zunyi Aluminum, pursuant to which we contributed all assets in Zunyi Alumina to Zunyi Aluminum. The appraised net value of Zunyi Alumina, equaling the appraised net value of its assets and liabilities, was RMB2,311 million. Upon completion of the merger, our shareholding in Zunyi Aluminum increased from 62.1% to 67.445%.

On June 24, 2018, Chinalco notified us of its plan to increase its shareholding in us via the trading system of the Shanghai Stock Exchange in an amount of not less than RMB400 million and not more than RMB1 billion in 12 months. Chinalco would, based on its reasonable judgment on our share price as well as the fluctuations of our share prices and the overall trend in the capital market, gradually implement the plan on increase in shareholding to the extent not exceeding 2% of our total share capital. The purpose of such increases in shareholding is to boost confidence of investors, protect the interests of minority shareholders and stabilize the capital market based on Chinalco’s confidence in the future development of the company and the recognition of our value.

For the period from June 25, 2018 to June 24, 2019, as the result of the aforesaid plan, Chinalco increased its shareholding in us by 160,512,964 A shares (representing approximately 0.94% of our total issued share capital as of June 24, 2019) in the amount of RMB608 million on a cumulative basis via the trading system of the Shanghai Stock Exchange. In addition, during the same period of time, Chinalco also, through its subsidiaries, had increased its shareholding in us by 115,276,000 H shares (representing approximately 0.68% of our total issued share capital as of June 24, 2019) in the amount of HK$365 million on a cumulative basis via the trading system of the Hong Kong Stock Exchange.

Acquisition of Carbon Assets and Equity Interests

On August 30, 2018, our Group and the affiliates of Chinalco Assets entered into a series of assets transfer agreements and equity transfer agreements for the acquisition of certain carbon assets and equity interests from the affiliates of Chinalco Assets, including: (i) the assets of the carbon plant under Shandong Aluminum Industry Co., Ltd; (ii) the assets of the carbon plant under Pingguo Aluminum Company Limited; (iii) 49% equity interests of Baotou Sendu Carbon Company Limited; and (iv) 57.69% and 19.96% equity interests of Chibi Great Wall Carbon Products Company Limited from two separate shareholders. Upon completion of the acquisition, we expect this acquisition would help us consummate our industrial chain, ensure our steady production, and improve our competitiveness and anti-risk capabilities, as carbon products are one of major raw materials for production of primary aluminum. As of December 2018, we had paid the total consideration of RMB735.6 million in full and the acquisition had been completed.

B.Business Overview

Our Principal Products

We are a leading enterprise in the non-ferrous metal industry in China. In terms of comprehensive scale, we ranked among the top enterprises in the global aluminum industry. We have benefited from the development of the PRC aluminum market, the world’s largest aluminum market. We refine bauxite into alumina, which is then smelted into primary aluminum. In addition to alumina and primary aluminum, we also produce and sell chemical alumina products (alumina hydrate and alumina-based industrial chemical products) and carbon products (carbon anodes and cathodes). We are also engaged in the trading and logistics of alumina, primary aluminum, other non-ferrous metal products, coal products and raw and ancillary materials in bulk manufactured by us or sourced from external suppliers domestically and abroad. In addition, we are engaged in coal mining and power generation. The remainder of our revenues was derived from research and development activities and other products and services. Accordingly, we organize and manage our operations in five business segments: alumina segment, primary aluminum segment, trading segment, energy segment and corporate and other operating segment. After elimination of inter-segment sales, revenues attributable to our alumina segment, primary aluminum segment, trading segment, energy segment, and corporate and other operating segment accounted for approximately 6.9%, 23.7%, 66.4%, 2.8% and 0.1%, respectively, of our total revenues in 2021.

Our alumina segment includes the mining and purchasing of bauxite and other raw materials, and production and sale of alumina as well as chemical alumina. Alumina accounted for approximately 93.1% of our total production volume for this segment in 2021. Chemical alumina products are used in the production of chemical, pharmaceutical, ceramic and construction materials. In the process of refining bauxite into alumina, we produce gallium as a by-product, which is a rare, high value metal with applications in the electronics and telecommunication industries.

Our primary aluminum segment includes the procurement of alumina, other raw materials, supplemental materials and electrical power, the production and sale of primary aluminum and aluminum-related products, such as carbon products, aluminum alloy products , renewable aluminum and other aluminum products. Our principal primary aluminum products are ingots, molten aluminum and aluminum alloys, which accounted for approximately 18.6%, 44.1% and 37.3%, respectively, of our total production volume of primary aluminum in 2021. Our standard 20 kilogram remelt ingots are used for general aluminum fabrication in the construction, electricity, electronics, transportation, packaging, machinery and durable goods industries. We internally produce substantially all the carbon products used at our smelters and sell our remaining carbon products to external customers.

30

Our trading segment is mainly engaged in the trading of alumina, primary aluminum, aluminum fabrication products, other non-ferrous metal products, and crude fuels such as coal products, as well as supplemental materials and logistics and transport services to our internal manufacturing plants and external customers. We established our trading business under Chalco Trading as a separate segment in July 2010 as a result of our operational structural adjustment. Since 2014, we have established Chalco Materials, Chalco Logistics and Chalco Trading Group to continuously promote and deepen development of our trading business, jointly constituting our trading segment. Established in 2018, Chalco Trading Group has undertaken the businesses that used to be operated by Chalco Trading.

Our energy segment includes the research and development, production and operation of energy products, including coal mining and conventional coal-fire power generation as well as renewable energy generation such as wind power and solar power. We are also engaged in new energy equipment production. We established our energy segment in January 2013 as a result of our acquisition of Ningxia Energy in line with our development strategy to partially offset our future energy costs. In 2021, we supplied the majority of the electricity we generated for our own production use, supplied a portion of the coal output to our own electric power plant and sold the remaining portion to external customers. Ningxia Energy supplied the electricity it generated mainly to the state grid in China.

Our corporate and other operating segment mainly includes corporate and other aluminum-related research, development, and our other activities.

Production Process

Alumina

Alumina is refined from bauxite, an aluminum-bearing ore, through a chemical refining process. The refining process applied is determined by the mineral composition of the bauxite used in production. Our refineries may employ the Bayer process, the Bayer-sintering series process, the Bayer-sintering combined process or the ore-dressing Bayer process. Most of the bauxite reserves in China contain diasporic bauxite, which contains high alumina content but relatively high silica content, resulting in bauxite reserves with low alumina-to-silica ratio. The Bayer process cannot efficiently refine diasporic bauxite that has not undergone processing to increase its alumina-to-silica ratio. The Bayer-sintering process and the Bayer-sintering combined process are suitable for refining low alumina-to-silica ratio bauxite. We have developed and improved these processes to increase our refining yield. In addition, we also produce some chemical alumina products (alumina hydrate and alumina-based industrial chemical products).

Primary Aluminum

We smelt alumina into primary aluminum through electrolytic reduction. The electrolytic process takes place in a reduction cell, or pot, a steel shell lined with carbon cathodes and refractory materials. Powerful electric currents are passed through the pot to produce molten aluminum. The molten aluminum is transferred to holding furnaces and then poured directly into molds to produce foundry ingots, or further refined to form fabricating ingots, which may be used directly in the aluminum fabrication process. The primary aluminum we produce is in the form of ingots, molten aluminum and aluminum alloys.

All of our primary aluminum smelters use pre-bake anode reduction pot-lines. In the pre-bake reduction process, the anodes are pre-formed in a separate facility where pollutants can be contained. The cells themselves are enclosed with removable panels so that the waste gas produced during the process can be extracted using large exhaust fans. Our waste gas is treated and purified to reduce dust and fluoride emissions to acceptable levels set by state environmental protection agencies.

Production Facilities

Alumina

We currently operate 11 alumina refineries and one research institute with a total designed annual production capacity of approximately 20.86 million tonnes as of December 31, 2021. Two of our refineries are integrated with primary aluminum smelters. In 2021, we produced approximately 16.23 million tonnes of alumina and approximately 4.12 million tonnes of chemical alumina products. The overall utilization rate for our refineries was 86% as of December 31, 2021.

Raw Materials

Alumina

Bauxite is the principal raw material in alumina production. Most of the bauxite in China is monohydrate, consisting mainly of aluminosilicate compounds. Bauxite deposits have been discovered across a broad area of central China and are especially abundant in the southern and northern parts of central China. The largest bauxite deposit in China lies in the Shanxi Province.

Rock Formation and Mineralization. Except for our Guangxi Pingguo mine which is an accumulation deposit due to original erosion, the bauxite deposits of our mines in China usually have similar stratigraphic sequences. Primary bauxite deposit, as a type of sedimentary boehmite (Al₂O₃.H₂O) of the Carboniferous or Permian age, is contained in clay rock, limestone or coal seams. A zonary red shale is usually located at the bottom of the bauxite and the red seam distributes over the irregular “karst-type” erosion face on the top of Ordovician limestone. Aluminum deposits in northern China are usually covered with a very thick Quaternary weathering.

The thickness and quality of deposits vary with our mine locations. Quality is usually consistent in smooth sections but changes sharply in karst “billabong” terrain. The level of hardness of minerals also varies. A sequence that includes a seam of hard bauxite of fine quality in the middle and soft bauxite of inferior quality on the bottom and top seams is common in deposits.

Generally, deposits are horizontal or with an obliquity of 0 to 8 degrees, but there are also steep deposits at an angle of 75 degrees, such as in our Guizhou mine. Most of the original mineralization is not influenced by folds and faults, and some fractures of a low obliquity and folds emerge in certain deposits, which is evident in the Guizhou mine area. In most of the Guizhou mine area, the underground mining method must be used due to the obliquity of its bauxite body reaching 70 degrees with the influence of folds and several meters of dislocation arising from partial faults.

Economic Significance. Our bauxite deposits in China are divided into three groups. They are primarily distinguished by drill hole spacing and the composition of the deposit, which can encompass rock formations such as intercalated clays, bauxite, footwall iron clay or Ordovician limestone. Bauxite deposit groups vary in the thickness and mineral quality of its reserves.

We use the Chinese bauxite deposit estimation method, which is calculated using cut-off grades and thickness to outline continuous areas within the limits defined by samples of marginal grade. We utilize actual limiting sample points that are joined to create a polygonal outline, and grades are then calculated using a length weighted arithmetic average. We believe that the Chinese bauxite deposit estimation method of test boring, inspection pit, trial trench, density, tonnage analysis and calculation applied to the geological work of bauxite in China is an appropriate method to analyze these types of deposits.

Supply. To support the growth of our alumina production, we continuously seek opportunities to streamline and optimize our bauxite procurement. Except for Chalco Shandong, all of our refineries are located in the four provinces where over 90% of China’s potentially mineable bauxite has been found. We generally source our domestic bauxite from mines close to our refineries to control transportation costs. Historically, we have procured our bauxite supply principally from three sources:

● our own bauxite mining operations, which include the mining operations of the Boffa mine in Guinea since 2020;

● jointly-operated mines; and

● other suppliers, which principally include small independent mines in China and international suppliers.

On average, our refineries consumed approximately 2.4 tonnes of bauxite to produce one tonne of alumina in 2021. Our mines supplied approximately 28.1 million tonnes of bauxite to our refineries in 2021. We purchase bauxite from a number of suppliers and do not depend on any supplier for our bauxite requirements.

34

The following table sets forth the volumes and percentages of bauxite supplied by our own mines and other suppliers for the periods indicated:

Total		39,291.1		100.0	44,221.5	100.0	44,344.3	100.0

(1) Including the bauxite supplied by the Boffa mine in Guinea since 2020.

(2) In 2019, bauxite supplied by our own mines exceeded the bauxite output from our own mines because we supplied certain inventory of bauxite extracted prior to 2019.

Own Mines. As of December 31, 2021, we owned and operated 14 mines in China that had approximately 173.01 million tonnes of aggregate bauxite reserves. In addition, we own Boffa mine in Guinea, which had approximately 111.69 million tonnes of total bauxite reserves as of December 31, 2021. In 2019, 2020 and 2021, we extracted approximately 14.4 million tonnes, 17.2 million tonnes and 16.0 million tonnes, respectively, of bauxite from our domestic mines. In addition, in 2020 and 2021, we extracted approximately 8.1 million tonnes and 12.3 million tonnes of bauxite from the Boffa mine, respectively. We continue to explore new bauxite reserves to replenish our reserves. Please refer to “– Our Mines” for further details of our own bauxite mines.

Other Suppliers. In addition to our mines, we also source bauxite from other suppliers. The majority of other domestic suppliers are small independent mines. Small independent mines are not affiliated with us and generally have annual bauxite production capacities not exceeding 200,000 tonnes. These mines have been an important source of bauxite for our operations. We purchase bauxite directly from small independent mines or through local distributors that procure bauxite from these mines. In addition, we also secure a portion of bauxite overseas. In 2021, bauxite secured from other suppliers accounted for approximately 36.5% of our total bauxite supply, primarily because our demand for bauxite exceeded the production of our mines.

Bauxite Procurement. The production and quality management department at our headquarters is responsible for the oversight and coordination of our supply of bauxite in general. The sales and marketing department is responsible for management and coordination of procurement of imported bauxite. To determine how our bauxite requirement will be allocated among our principal sources each year, we first estimate our total bauxite needs for the year. Based on market conditions, production costs and other factors, we determine the amount of bauxite that we wish to source from our mines, and the remaining requirements from other suppliers.

Alumina-to-Silica Ratio. The production method for alumina refining is determined by the mineral composition of the bauxite, in particular, its alumina-to-silica ratio. Most of the bauxite reserves in China are diasporic with low alumina-to-silica ratios. Based on our current technology and economic considerations, an efficient application of the Bayer process requires bauxite with an alumina-to-silica ratio of 4.5:1 or higher, while the Bayer-sintering process can refine bauxite with an alumina-to-silica ratio as low as 4:1. In 2021, the average alumina-to-silica ratio of the proven and probable reserves of our mines ranges from approximately 3.73:1 to 34.16:1.

Prices. There is neither governmental regulation on bauxite prices nor an official trading market for bauxite in China. We negotiate bauxite prices with our suppliers based on ore quality, mining costs, market conditions, transportation costs and various governmental taxes or levies, including a resource tax imposed by local governments. Our total bauxite cost is currently influenced by the following factors:

● the cost of our mining operations;

● the market conditions relating to purchases from small independent mines; and

● the market conditions relating to purchases from overseas.

35

The average purchase price of bauxite per tonne from our other suppliers in 2021 decreased by approximately 6.2% to RMB386.83 compared to 2020, primarily because (i) with higher bargaining power due to less reliance on external bauxite suppliers, we were able to procure bauxite from external suppliers with a lower price in 2021, and (ii) the international freight decreased in 2021, in each case compared to that in 2020. The average cost of bauxite per tonne from our own mines is mainly related to the cost of our bauxite mining operations and transportation costs. In 2021, the average cost of bauxite per tonne from our own mines increased by approximately 6.3% to RMB299.03 compared to 2020, mainly due to increase of the cost of our bauxite mining operations.

We purchase a substantial amount of bauxite to satisfy our alumina production needs. Additionally, to fully utilize the bauxite from our mines, we refine all bauxite that meets the minimum technical requirements for our production of alumina. We also purchase higher-grade ore from other suppliers and blend the ore of various grades to meet the technical requirements for our alumina production. This practice allows for flexibility and the inclusion of lower-grade bauxite to optimize the use of bauxite deposits available to us.

Primary Aluminum

An average of approximately 1.91 tonnes of alumina and 13,361 kWh of electricity was required to produce one tonne of primary aluminum ingots in 2021.

Alumina and electricity, the two principal components of costs in the smelting process, accounted for approximately 40% and 37%, respectively, of our unit primary aluminum production costs in 2021. Apart from alumina and electricity, we also require carbon anodes, carbon cathodes, fluoride salt and cryolite for our smelting operations.

Alumina is the main raw material used in the production of primary aluminum. Our primary aluminum plants that do not have integrated alumina refining operations onsite obtain alumina internally from our alumina refineries located elsewhere or externally on the market.

(1) All conditions to retain our properties or leases have been fulfilled as of December 31, 2021. Each mine may be covered by one or more mining permits and/or exploration permits and the range of permit renewal dates is set forth above.

(2) We have modern facilities at our bauxite mines in China, which were designed by professional PRC mine design institutes and adhere to international standards. Our bauxite mines are either open pit or underground. Our bauxite mines generally have mining offices and transportation facilities that have access to local roads and highways. In addition, we utilize advanced heavy equipment such as bulldozers and scrapers. All of our mining facilities in China are connected to the local or regional electric power grids. Our mining facilities are also connected to reliable water sources, all of which were sufficient for the requirements of each individual mine. For details of the processing plants and other available facilities for these mines, see “– Principal Facilities.”

(3) We are in the process of renewing these permits.

(4) Including both Guizhou No. 1 mine and Guizhou No. 2 mine throughout this annual report.

(5) To enhance our mine management system and improve management efficiency and coordination, in 2020, Mianchi mine was renamed as Sanmenxia area business department; Luoyang mine was renamed as Luoyang area business department; Xiaoguan mine, Gongyi mine, Dengfeng mine and Xinmi mine were integrated as Zhengzhou area business department; and Xuchang mine and Pingdingshan mine were integrated as Xuping mine. These new names are used throughout this annual report.

(6) As disclosed in “– C. Organizational Structure,” Chalco does not own 100% ownership interests of Shanxi New Material. Nevertheless, Chalco holds the permits for 100% interests of Xiaoyi mine and Shanxi Other Mines while Shanxi New Material is the operator of these mines.

(7) For details of our sole individually material mining property, Boffa mine, please refer to “– D. Property, Plants and Equipment – Boffa Mine.”

For the years ended December 31, 2019, 2020 and 2021, we extracted approximately 14.4 million tonnes, 17.2 million tonnes and 16.0 million tonnes, respectively, of bauxite from our domestic mines. In addition, in 2020 and 2021, we extracted approximately 8.1 million tonnes and 12.3 million tonnes of bauxite from the Boffa mine, respectively. The decrease in the volume of bauxite extracted from our domestic mines in 2021 was primarily because (i) some of the mine resources depleted and the replacements failed to meet the previous output in a timely manner, (ii) safety and environmental protection control standards improved in some regions where certain mines were located, (iii) we proactively reduced the production of a small number of mines with low-grade ore. The increase in the volume of bauxite extracted from Boffa mine in 2021 was primarily because our Boffa mine entered into normal operation stage for the full year of 2021.

We hold the requisite mining permit for three bauxite mines (i.e. PT ALUSENTOSA, PT KALMIN and PT VISITAMA) in West Kalimantan, Indonesia through our 96.28% owned subsidiary, PT Nusapati Prima. Our bauxite deposits in Indonesia are lateritic gibbsite and were formed by weathering and leaching of aluminum-rich silicate rock in tropical climates. We have suspended our bauxite mining in Indonesia since September 2014 due to restraints on export of bauxite imposed by the Indonesian government. Since 2017, the Indonesian government has issued, and amended from time to time, relevant rules pursuant to which export of bauxite may be allowed upon satisfaction of certain requirements. We have been actively exploring the possibility of meeting these requirements. However, Indonesia plans to stop the exports of bauxite in 2022. We do not expect to engage in exploration, development or production of bauxite on PT ALUSENTOSA, PT KALMIN or PT VISITAMA mines in the near future. Our mines in Indonesia have access to local roads. The mineral resources and mineral reserves of PT ALUSENTOSA, PT KALMIN and PT VISITAMA are also not available.

We are required to obtain mining rights permits to conduct mining activities. Under PRC laws and regulations, a mining enterprise must prepare and submit exploration reports for a mine to the local government to obtain a mining rights permit for a mine. A mining right owner is also permitted to lease the mining right through a lease arrangement. The mining rights permit is subject to renewal on a regular basis.

Furthermore, the mining right owner is required to obtain land use rights on the land in order to operate the mines. We lease the land use rights relating to our mines in China from Chinalco pursuant to a land use rights lease agreement that became effective upon our formation. Chinalco’s land use rights relating to over 90% of our mining properties in China are for 50-year terms beginning on July 1, 2001. The remaining land use rights relating to other mines in China are for shorter terms, some as short as one year. All of our land use rights lease agreements end on the expiry date of the mining rights or the end of the working life of the mine, whichever is earlier. Both the land use rights and land use rights lease agreements are renewable.

The following table sets forth our capital expenditures for our bauxite mines for the periods indicated:

	Year Ended December 31,
	2019	2020		2021
	(RMB in thousands)
Capital Expenditures
Infrastructure construction	1,314,802.9	831,375.0	(1)​	279,536.0	(1)​
Facility upgrade	6,079.8	—	(2)​	—
Total	1,320,882.7	831,375.0		279,536.0

(1) The decreases in capital expenditures on infrastructure construction in 2020 and 2021 were primarily attributable to the completion of construction of the Boffa Project in April 2020. See “– A. History and Development of the Company – Boffa Project” for more details.

(2) The decrease in capital expenditures on facility upgrade in 2020 was primarily because our technology transformation projects had been completed and we did not have any new technology transformation projects in 2020.

Coal Mines

As of December 31, 2021, our non-wholly owned subsidiaries owned and operated five coal mines in China.

We completed the acquisition of 70.82% of the equity interest in Ningxia Energy in January 2013, which holds mining rights or exploration rights for certain coal deposits in Ningxia Autonomous Region. The coal mines directly owned and operated by Ningxia Energy include Wangwa mine, Wangwa No.2 mine and Yindonggou mine. In addition, Ningxia Energy holds 50% of interest in Ningxia Yinxing Coal Industry Co., Ltd., which owns and operates Yinxingyijing mine. As the other 50% owner of in Yinxingyijing mine does not participate in its operation, Ningxia Energy is able to control its operation and consolidate its financial statements. Each of Wangwa mine, Wangwa No.2 mine, Yindonggou mine and Yinxingyijing mine is an underground thermal coal mine in extraction stage. The operations at these coal mines are powered by electricity from local power grids and are accessible by public roads. For the year ended December 31, 2021, Ningxia Energy incurred capital expenditures of approximately RMB360.4 million on infrastructure construction.

We acquired 70% of the equity interest in Gansu Huayang in March 2011, which holds exploration rights for a portion of Luochuan mine in Gansu Province. We renewed the exploration permit in 2020, which will expire in October 2025. We are in the process of applying for the exploration permit for the rest of Luochuan mine. Luochuan mine is an underground mine. We have completed the exploration but have not commenced development of Luochuan mine.

Summary of Mineral Resources

A “mineral resource” is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade, or quality and quantity that there are reasonable prospects for eventual economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed adjustifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled. A “measured mineral resource” is a resource for which the quantity and grade are estimated from detailed, closely spaced sampling, and geologic characterization that defines the size, shape, depth and mineral content to a high degree of confidence. An “indicated mineral resource” is a resource for which quantity and grade are estimated from information similar to that used for measured mineral resources where the samples are farther apart, and the geological characterization is adequate. An “inferred mineral resource” is a resource for which quantity and grade are estimated from information similar to that used for measured and indicated mineral resources, but with limited geological evidence and sampling. Inferred mineral resource grade and mineralization continuity have a lower degree of confidence. Accordingly, no assurance can be given that the estimated mineral resources not included in mineral reserves will become proven and probable mineral reserves. The measured, indicated, and inferred resource figures presented herein are estimates based on information available at the time of calculation and are exclusive of reserves.

The following table sets forth certain estimated details of the measured, indicated and inferred resources, exclusive of mineral reserves, for our bauxite mines as of December 31, 2021:

Such prices are the respective average selling price of coal extracted from these mines during 2021. The point of reference selected by the qualified person is the point where raw coal mined from the coal mines can be saleable product after being washed by the supporting coal preparation plant.

Summary of Mineral Reserves

A “mineral reserve” is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. The term “economically viable,” as used in the definition of reserve, means that the qualified person has analytically determined that extraction of the mineral reserve is economically viable under reasonable investment and market assumptions.

The term “proven reserves” means the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. The term “probable reserves” means reserves for which quantity and grade are computed from information similar to that used for proven reserves, but the sites for sampling are farther apart or are otherwise less closely spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation. Our proven and probable reserves include bauxite or coal attributable to our ownership or economic interest.

Proven and probable mineral reserves were determined from the application of relevant modifying factors to geological data, in order to establish an operational, economically viable mine plan. The proven and probable reserve figures presented herein are estimates based on information available at the time of calculation. No assurance can be given that the indicated levels of recovery of bauxite or coal will be realized. Reserve estimates may require revision based on actual production. Market fluctuations in the price of aluminum and coal, as well as increased production costs or reduced metallurgical recovery rates, could render certain proven and probable reserves containing higher cost uneconomic to exploit and might result in a reduction of reserves.

The point of reference selected by the qualified person is the point where raw coal mined from the coal mines can be a saleable product after being washed by the supporting coal preparation plant.

Internal Controls over the Mineral Reserves and Mineral Resources Estimation Process

We have internal controls over the mineral reserves and mineral resources estimation processes that are able to reach reasonable and reliable estimates aligned with industry practice and reporting regulations, which includes (i) a quality control and quality assurance plan, and (ii) verification of analytical procedures.

With respect to quality control and quality assurance, we engage third-party professional technical firms to conduct the mineral exploration and mineral resources estimation, the results of which are evaluated by internal and external experts. The conversion of mineral resources into mineral reserves is determined by third-party professional consulting firms based on feasibility studies or pre-feasibility studies, or supported by mine production data. The estimates of mineral resources and mineral reserves by third-party professional firms will first be reviewed by Chalco’s internal experts, and then reviewed and confirmed by the qualified person to ensure the reliability of mineral reserves and mineral resources estimation results. The annual report and results of mineral reserve and resources estimation of coal mines are also filed with the Department of Natural Resources of the local government.

The verification of analytical procedures is entrusted to third-party qualified firms. The fundamental analysis of the samples is carried out by a certified laboratory. During the analysis, standard samples were used for quality control. At the same time, duplicate samples were taken according to the ratio of 7% to 10% by such laboratory. In each batch of analysis samples, 3% to 5% of the samples are taken and sent to another certified laboratory for external inspection and analysis, and standard samples are also used for quality control during external inspection and analysis.

These controls and other measures help to validate the reasonableness of the estimates of our mineral resources and mineral reserves. However, estimates could change due to a number of factors, including future changes in permitting requirements, geological conditions, ongoing mine planning, macroeconomic and industry conditions, and regulatory disclosure requirements. The industry risks to which estimates are subject include risks related to metal prices, metallurgical performance and geological modeling. Please refer to “Item 3. Key Information – D. Risk Factors – Estimates of mineral reserves and mineral resources are uncertain and the volume and grade of minerals actually extracted may vary from our estimates” for a discussion of risks inherent in our estimates of mineral resources and mineral reserves.

Mine Safety Disclosure

We have been in compliance with the PRC National Mining Safety Law and related rules and regulations in China. We closely supervise and routinely inspect mining conditions with continual implementation of safety measures and procedures at our own bauxite mines and safety trainings for our mining personnel. For our Boffa mine, we strictly abide by the mining convention with the Guinean government and Guinean laws and regulations relating to mining. We continuously screen, identify and control safety hazards and regularly organize safety trainings for our personnel. In 2021, we extracted approximately 16.0 million tonnes of bauxite from our domestic mines and approximately 12.3 million tonnes of bauxite from the Boffa mine. We did not experience any mining operation-related accidents that involved serious work injuries or death.

Supplemental Materials, Electricity and Fuel

The sales and marketing department at our headquarters coordinates and manages our supply chain for all our major raw materials in conjunction with the procurement center at each production facility, which manages the logistics and inventory of raw materials locally. We are able to purchase diesel, the main fuel used by our mining and manufacturing equipment, from the public markets, and we source our water from local rivers, lakes or underground sources.

Alumina

Electricity, coal, alkali (caustic soda or soda ash) and natural gas are the principal materials and energy used in our alumina production. Electricity is one of the principal cost components in our refining process. We generate electricity at a number of alumina refineries and meet our remaining electric power requirements through purchasing from regional power grids at government-mandated rates or directly from power generation enterprises. Most of our power supply agreements have a term of one year and are renewed by mutual agreement. Power prices in China can vary, sometimes substantially, from one region to another, based on demand and power production costs in the region. Power costs for our various alumina refineries vary accordingly.

46

Large quantities of coal are used as a reducing agent and fuel to produce steam and gas in the alumina refining process. See “– B. Business Overview – Our Mines” for details of coal mines of which we own majority or minority interests. By investing in coal mining enterprises and acquiring mining rights for coal deposits, we plan to partially offset our future energy costs.

Alkali is used as a supplemental material in alumina refining. The Bayer-sintering process and the Bayer-sintering combined process require soda ash while caustic soda is used in the Bayer process. Our alumina refineries use natural gas and coal gas as fuel to refine alumina. There is no governmental regulation of the prices of coal, alkali or fuel. We purchase these raw materials from external suppliers under negotiated supply contracts, which we believe are competitively priced. We have not experienced difficulty in obtaining these materials in sufficient quantity and at acceptable prices.

Primary Aluminum

Electricity, carbon anodes and cathodes are the principal materials and energy used in our smelting process. Smelting primary aluminum requires a substantial and continuous supply of electricity. The availability and price of electricity are key factors in our primary aluminum production. See “Item 5. Operating and Financial Review and Prospects - A. Operating Results - Overview - Factors Affecting Our Results of Operations - Manufacturing Costs.”

We generate electricity at four of our smelters to supply a portion of the electricity consumed by these smelters. We meet our remaining electric power requirements through purchasing directly from power generation enterprises. As of December 31, 2021, five of our smelters had direct purchase arrangements with power generation enterprises and the rest of our smelters were in the negotiation process for the renewal of direct purchase arrangements. In 2021, direct purchase transactions were organized by the local government. Starting from January 1, 2022, direct purchase transactions have been carried out based on the relevant rules and regulations in different regions. Because power prices in China vary from one region to another, power costs for our various smelters could vary substantially. The average electricity cost (including tax) of our smelters increased by 27% from 2020 to 2021.

Carbon anodes and cathodes are key raw materials in the smelting process. We are generally able to manufacture carbon anodes necessary for the operations of our smelters. In addition, our Qinghai branch possesses production capacity of carbon cathodes and is able to manufacture carbon cathodes products.

Sales and Marketing

We coordinate substantially all of our sales and marketing activities for our self-produced alumina products and some of our sales and marketing activities for our self-produced primary aluminum products through Chalco Trading Group. Our subsidiaries and branches sell some of our self-produced primary aluminum products directly to external customers. Our alumina refineries sell our self-produced chemical alumina products directly to external customers or indirectly through Chalco Trading Group for subsequent external trading. For all of our self-produced products that are sold either through Chalco Trading Group for subsequent external sale or directly to external customers, our subsidiaries and branches play an important role in providing after-sale services and strengthening our presence in the marketplace. Since late 2009, we have also been engaged substantially in the trading of non-ferrous metal products including alumina, primary aluminum, copper, zinc and lead, as well as coal products that we source from third-party suppliers through Chalco Trading Group, or previously Chalco Trading.

Alumina

We sell our self-produced alumina to external customers primarily through Chalco Trading Group, giving priority to customers with whom we have long-standing relationships and who have established a strong credit history, after reserving sufficient alumina for our forecasted primary aluminum production. In 2021, we supplied approximately 7.1 million tonnes of alumina produced at our alumina refineries to our smelters, which represented approximately 43.8% of our total alumina production, and sold the remainder to our customers. In addition, we also procure and sell outsourced alumina under long-term agreements or on the spot market through Chalco Trading Group. We sold approximately 1.9 million tonnes of outsourced alumina in 2021.

The sales prices of alumina that our alumina refineries sell internally to Chalco Trading Group are determined based on our budgeted sale prices, spot market prices and the prices of primary aluminum on SHFE. Chalco Trading Group coordinates the external negotiation and execution of sales contracts of our alumina products. Chalco Trading Group sells our self-produced alumina and alumina sourced from third-party suppliers to customers throughout China. Most of our major customers in the past three years have been domestic smelters. We primarily sourced alumina from third-party suppliers on the spot market, and we are normally required to pay the full price of the outsourced alumina before each delivery.

47

Chalco Trading Group sells our self-produced alumina and outsourced alumina under spot sales agreements and long-term sales agreements with terms ranging from one year to three years. Our long-term sales agreement for alumina normally sets forth the quantity of alumina to be sold by us in each month and each year, the price determination mechanism, payment method, place of delivery and delivery method. Places of delivery under our sales agreements are arranged to be where we could efficiently manage the transportation of alumina and help reduce logistics cost. Our customers are normally required to pay for their procurement before each delivery. As a result, the spot price of alumina and fluctuations of primary aluminum prices on the SHFE affect the alumina prices at which we sell.

Chalco Trading Group sets the price for the external sales of alumina products after taking into account the following factors:

● international and domestic supply-demand situation;

● CIF Chinese ports prices for alumina imports into China and other relevant import expenses;

● international and domestic alumina transportation costs;

● effects of the PRC government’s policies on raw materials required by our alumina refineries; and

● our short-term and mid-term projections for alumina prices.

Primary Aluminum

We sell all of our self-produced and outsourced primary aluminum to domestic customers. We expect China to remain our key market for primary aluminum for the foreseeable future. Customers of our primary aluminum products principally consist of aluminum fabricators and distributors that resell our primary aluminum products to aluminum fabricators or other purchasers.

To improve the efficiency of our distribution, we divide our China market into the following regions: southern China (including Guangdong and Fujian Provinces); eastern China (including Jiangsu and Zhejiang Provinces and Shanghai Municipality); southwestern China (including Sichuan Province and Chongqing Municipality); the Beijing-Tianjin-Tanggu area; and central China. In general, we satisfy each purchase order with products from our nearest smelter to minimize transportation costs.

Our primary aluminum smelting subsidiaries and branches sell a portion of our primary aluminum output directly to external customers. Each of our smelters is normally responsible for the sale of products to the customers from neighboring markets, negotiating the pricing and delivery terms based on market conditions.

Our primary aluminum smelting subsidiaries and branches also sell a portion of our primary aluminum output internally to Chalco Trading Group at prices based on the spot prices of primary aluminum on Yangtze or Nanchu. We establish pricing guidelines for Chalco Trading Group to conduct external domestic sales of our self-produced primary aluminum products, taking into account four main factors: the primary aluminum spot prices and futures price on the SHFE; spot prices in the regions of eastern China and southern China; our production costs and expected profit margins; and supply and demand. Chalco Trading Group then coordinates the external sales of primary aluminum. Chalco Trading Group sells our self-produced primary aluminum products to external customers through the following three channels:

● Contract sales. Most of our primary aluminum sales are made pursuant to contracts entered into directly with our long-standing customers. The terms for our sales contracts for primary aluminum are typically one year. We price our primary aluminum products based on the SHFE prices and spot market prices for primary aluminum.

● Sales on the SHFE. As part of our effort to manage market risk, we sell a portion of our primary aluminum products on the SHFE through futures contracts with terms ranging from one month to 12 months to hedge against declines in primary aluminum prices.

● Sales on the spot market. We also sell our primary aluminum products on the spot market at prices with reference to various factors, such as market spot prices and transportation costs.

48

In addition, we also procure and sell outsourced primary aluminum on the spot market or through short-term futures and options transactions. We determine our sales prices of the outsourced primary aluminum through negotiations with our customers, taking into consideration factors including our procurement prices and prevailing market conditions. We sold approximately 5.8 million tonnes of outsourced primary aluminum in 2021.

Chemical Alumina Products and Gallium

Chemical alumina products are derived from our alumina production. We adjust our production of these products based on market demand. Our alumina refineries sell our chemical alumina products directly to external customers or indirectly to external customers through Chalco Trading Group for subsequent external trading. We sell most of our chemical alumina products in China. Prices for our chemical alumina products are determined through negotiations with our customers, taking into consideration the market conditions.

In addition, in the process of refining bauxite into alumina, we produce gallium as a by-product. We adjusted our production of gallium based on market demand. Prices for our gallium were determined through negotiations with our customers, taking into consideration the market conditions.

Coal

Ningxia Energy sells a portion of its self-produced coal directly to external customers through short-term contracts at prices determined through negotiations with our customers, taking into consideration factors including our procurement prices and prevailing market conditions. Ningxia Energy consumes the rest of its self-produced coal at its own electric power plant.

In addition, we also procure and sell outsourced coal under long-term agreements or on the spot market through Chalco Trading Group. We sold approximately 2.0 million tonnes of outsourced coal in 2021.

Trading of Outsourced Non-ferrous Metal Products and Other Materials

Since late 2009, we have been actively engaged in the trading of alumina and primary aluminum sourced from third-party suppliers. Please see “– Alumina” and “– Primary Aluminum” for more details. Through Chalco Trading Group, we also sell other non-ferrous metal products such as copper, zinc and lead as well as coal products that we procure from our third-party suppliers to external customers on the spot market or under long-term sales agreements. Please see “– Coal.” In 2021, we sold approximately 0.8 million tonnes of outsourced electrolytic copper, copper concentrate and zinc. In addition, we also sell outsourced raw and ancillary materials such as iron ore, charred coal and cathode copper in bulk to customers such as steel manufacturers and copper processing companies on the spot market.

Chalco Trading Group has a team with trading expertise to conduct research on the markets of non-ferrous metal products and other materials. From time to time, we may enter into futures and options transactions to hedge against price fluctuations in the non-ferrous metal product market.

Delivery

We rely on rail shipping and trucks for the delivery of products within China.

Our alumina is transported by rail or trucks, and transportation costs are generally borne by our customers and excluded from our sales prices. For long-distance deliveries, we maintain spur lines connecting our plants to the national railway routes.

Our molten aluminum is delivered to our customers primarily by trucks. Other primary aluminum products are primarily transported by rail. Our coal products are transported both by trucks and by rail.

Rail shipping on the PRC national railway system is subject to government mandated pricing.

Competition

Competition from Domestic Competitors

Alumina

In 2021, we supplied approximately 43.8% of our total production of alumina to our own smelters and sold substantially all of the remaining self-produced alumina to our domestic customers. Our competitors mainly include other domestic and international alumina producers that conduct sales in China. In 2021, our alumina production (with chemical alumina products included) represented approximately 23.6% of total domestic production in China.

We are a leading enterprise in the non-ferrous metal industry in China. As of December 31, 2021, 39 alumina producers in China (including Chalco) each had annual production capacity of 500,000 tonnes or above, which collectively represented approximately 96.5% of the total alumina production capacity in China. As of the same date, among these 39 alumina producers, 24 alumina producers (including Chalco) each had annual production capacity of one million tonnes or above, which collectively represented approximately 81.4% of the total alumina production capacity in China. In order to improve the efficiency and competitiveness of the Chinese alumina industry as well as to protect the environment, MIIT published the Standard Conditions for Aluminum Industry in July 2013 and issued a new version in March 2020, which provides stringent standards for the existing alumina enterprises. Although we face competition from other domestic and international refineries, we have several advantages over such competitors, including:

● we have access to a substantial and stable supply of bauxite;

● we are experienced in alumina production and our production technologies are specifically adapted to the particular chemical composition of bauxite found in China;

● we have strong capabilities in technology research and hold certain proprietary technologies and patents; and

● we have a substantial workforce that has extensive experience in production and management.

54

Primary Aluminum

We derived all of our primary aluminum revenues from domestic sales in 2021. Our competitors include other domestic and international primary aluminum producers that conduct sales in China. In 2021, our primary aluminum production represented approximately 10.1% of total domestic production in China.

We are a leading enterprise in the non-ferrous metal industry in China. As of December 31, 2021, 34 primary aluminum producers in China (including Chalco) each had annual production capacity of 500,000 tonnes or above, which collectively represented approximately 62.5% of the total primary aluminum production capacity in China. As of the same date, among these 34 primary aluminum producers, seven primary aluminum producers (including Chalco) each had annual production capacity of one million tonnes or above, which collectively represented approximately 21.1% of the total primary aluminum production capacity in China. The PRC government encourages consolidation in the Chinese primary aluminum industry to create larger, more efficient producers that are better positioned to implement measures to reduce emissions. Moreover, according to the current Standard Conditions for Aluminum Industry and other administrative regulations, aluminum smelting enterprises must ensure the availability of resources, energy and water resources, and are encouraged to merge with hydropower, coal power and other power enterprises through reorganization. Alumina and electrolytic aluminum enterprises are required to comply with environmental laws, regulations and policies, and establish, implement and maintain an environmental management system.

Although we face competition from other domestic and international smelters, we have several advantages over such competitors, including:

● Scale of production. With nine primary aluminum smelters, we can achieve significant economies of scale. In addition, our scale of production enables us to achieve high production volumes to fill large customer orders and maintain a large customer base. Through our national distribution network, we are able to make timely deliveries to customers from our local warehouses.

● Technology. We believe we have a more sophisticated technological innovation system and stronger innovation capability than most of our domestic competitors. In terms of technological support and research and development capabilities, we are equipped with the most advanced research and development institute within the aluminum industry in China and enjoy advantages over other domestic smelters in technology advancement.

● Vertical integration. As a leading integrated alumina and primary aluminum producer in China, we are able to supply alumina internally to our primary aluminum plants. As a result, we save on transportation, warehousing and related costs. In addition, because we operate our own alumina refineries, we are able to assure a stable supply of alumina for our primary aluminum smelting operations.

● Quality. We have maintained and will continue to improve on the high quality standards for our primary aluminum, which has satisfied national and industrial standards and customers’ need.

The primary aluminum produced by most of our smelters satisfies the quality standards of the LME.

Competition from International Competitors

The tariff rate for alumina and primary aluminum imports remained zero in 2021. In 2021, China had a net import of approximately 3.21 million tonnes of alumina (with chemical alumina products included), a decrease from a net import of 3.65 million tonnes in 2020, primarily attributable to the fact that the supply of alumina in the international market decreased in 2021 and we imported less alumina compared to 2020. China had a net import of approximately 1.57 million tonnes of primary aluminum in 2021, compared to a net export of approximately 1.06 million tonnes of primary aluminum in 2020, primarily because the production curtailment policy in Yunnan has affected the production of the facilities in Yunnan and resulted in increased prices of domestic primary aluminum. We expect to continue to face competition from international suppliers of alumina and primary aluminum which are large international companies.

55

Research and Development

Our research and development efforts over the years have facilitated the expansion of our production capacity and reduced our unit costs. We have successfully commercialized our previous research and development results in various technologies. In 2021, we completed 263 technological projects, including 244 research and development projects undertaken independently by our branches or subsidiaries, seven special key science and technology projects and 12 science and technology application projects. In addition, we filed a total of 203 patent applications in 2021.

As of December 31, 2021, we owned 1,486 patents, which were primarily related to technologies and processes, equipment and new products. Once granted, a patent in China for an invention is valid for 20 years and for a utility model or a design 10 years from the date of the patent application. As of December 31, 2021, we owned 25 trademarks, each of which had a term of 10 years.

We do not regard any single patent, license, or trademark to be material to our sales and operations as a whole. We are not involved in any material intellectual property disputes.

Environmental Protection

Our operations are subject to PRC national and local environmental laws and regulations, including laws and regulations governing pollutant emissions, waste generation, treatment and disposal of hazardous materials, land reclamation and environmental issues associated with mining.

The pollutants discharged from our alumina refining process include red mud, waste water and gas emissions and particulates. Our primary aluminum production process generates fluorides, sulphur dioxide and particulates. It is illegal to release these pollutants untreated. The discharge of these pollutants after treatment must comply with national and local discharge limits.

Each of our alumina refineries, primary aluminum smelters and other production plants has its own waste treatment facilities onsite or has developed other methods to dispose of industrial waste in compliance with applicable environmental laws and regulations. Each of our production plants has established its environmental management system. All of our alumina refineries, primary aluminum smelters and carbon production plants in production passed the ISO14001 accreditations.

We have increased our energy efficiency by implementing new production techniques and technologies, upgrading our production facilities, optimizing our production process and enhancing our logistics and operations management. In 2021, we saved energy equivalent to 299,292 tonnes of standard coal as a result of implementing new production techniques and technologies, upgrading our production facilities, optimizing our production process and enhancing our logistics and operations management. We have established the industrial waste water recycling system. All of our aluminum smelting plants have achieved “zero discharge” of industrial waste water and 100% of the industrial waste water is reused for production after treatment.

In addition, we have focused on sustainable development of mine sites and achieved significant progress in mine reclamation. We reclaimed 12.8 thousand hectares of land throughout the year 2021, representing a cumulative reclamation rate of over 100% as of December 31, 2021.

Our total expenditures for maintaining compliance with environmental laws and regulations were RMB914 million, RMB1,171 million and RMB1,384 million for 2019, 2020 and 2021, respectively. In 2021, we did not have any major environmental pollution incidents.

Insurance

We maintain insurance coverage for our fixed assets such as plant, machinery, equipment, office facilities and transportation vehicles against accidents or natural disasters such as typhoons, hurricanes, floods, landslides and lightning strikes. However, there are certain types of losses, such as losses from war, acts of terrorism and nuclear radiation, for which we cannot obtain insurance at a reasonable cost or at all.

We are covered under the work-related injury insurance required by the relevant local government labor departments, and we have procured additional business accidental insurance for our employees. More extensive insurance is either unavailable in China or would impose a cost on our operations that would reduce our competitiveness.

56

Our insurance premiums were RMB42.9 million, RMB38.6 million and RMB45.6 million in 2019, 2020 and 2021, respectively.

Seasonality

Our business in general is not subject to seasonality. Separately, our bauxite output in the Boffa mine may be subject to seasonal fluctuations due to the rainy season in Guinea.

Cybersecurity

With respect to our internal internet policies on cybersecurity, we have established an information safety management system and issued internal regulations on cybersecurity, internal hardware and data safety systems and we are gradually implementing measures relating to the office environment information safety management, information system access control, protection from any malicious software, and internal review and audit of information safety risks, in order to prevent loss of information due to cybersecurity incidents, network outages or hardware incidents. In 2021, we did not experience any material cybersecurity incidents or related losses.

Regulatory Overview

Producers of alumina and primary aluminum are subject to national industrial policies and relevant laws and regulations in areas of environmental protection, import and export, land use, foreign investment regulation and taxation. We are also subject to regulations relating to activities such as mining.

We are principally subject to governmental supervision and regulation by four agencies of the PRC government:

● the NDRC, which sets and implements the major policies concerning China’s economic and social development, approves investments exceeding certain amounts, coordinates and improves the reform of the economic system;

● the Ministry of Natural Resources of China, which has the authority to grant land use rights and mining right permits;

● the MIIT, which formulates industrial policies and investment guidelines for all industries, including the aluminum industry; and

● the CSRC, the securities regulatory commission of China.

The following is a brief summary of the principal laws, regulations, policies and administrative directives to which we are subject.

Requirements for Capital Investments

Any capital markets financing activities by an enterprise or company incorporated in the PRC such as those to finance capital projects, are subject to approval by the CSRC and/or other relevant authorities in China, regardless of whether the funds are raised in China or on the international capital markets. An issuer incorporated in the PRC must obtain prior approval from the CSRC for issuance of equity securities or equity-linked securities. Offering of corporate bonds in the PRC is also subject to supervision of the CSRC. Offering of bonds by a PRC-incorporated company outside the PRC shall be filed with NDRC. For all overseas financing activities by an enterprise or company incorporated in the PRC, the issuer must register with and obtain prior approval from the administrative authorities of foreign exchange. Foreign investment in the exploring and mining of alumina and primary aluminum is permitted by the PRC government.

57

Standard Conditions for Aluminum Industry

The Standard Conditions for Aluminum Industry was issued by MIIT on July 18, 2013 and a new version was issued on February 28, 2020 to replace the 2013 version, which became effective on March 30, 2020. The new Standard Conditions for Aluminum Industry only applies to existing bauxite mining, alumina and primary aluminum enterprises and indicates that such standards do not constitute administrative approval or mandatory requirement. It provides that bauxite mining, alumina and primary aluminum production must comply with the state and local industry policies and overall plans on the mining resources and development of aluminum industry, as well as laws, regulations and policies related to the environmental protection, energy conservation, mining and production safety. According to the new Standard Conditions for Aluminum Industry, aluminum smelting enterprises must ensure the availability of resources, energy and water resources, and are encouraged to merge with hydropower, coal power and other power enterprises through reorganization. It further encourages that alumina enterprises use intelligent systems and equipment in their operations to achieve energy-conserving and environment-protective purposes. The new Standard Conditions for Aluminum Industry further set out guidelines and standards for enterprises in the aluminum industry regarding product quality, facilities, energy consumption, resources consumption, environmental protection, production safety and occupational disease prevention.

Under the Standard Conditions for Aluminum Industry, the MIIT shall, in accordance with the applicable regulatory standards, review the applicants and disclose the names of applicants that meet the regulatory conditions. The MIIT promulgated on April 4, 2014, January 4, 2015 and February 14, 2016, respectively, the first, the second and the third lists of enterprises that meet the Standard Conditions for Aluminum Industry of 2013. Most of our production branches and subsidiaries have met the Standard Conditions for Aluminum Industry of 2013 version and are included on these lists. According to the current Standard Conditions for Aluminum Industry, enterprises that would like to be named in the list under this new Standard Conditions for Aluminum Industry need to resubmit application for the MIIT’s review. The MIIT promulgated the first list of enterprises that meet the Standard Conditions for Aluminum Industry of 2020 version on January 5, 2021, which includes three of our production branches and subsidiaries. We are actively taking rectification measures to comply with the new Standard Conditions for Aluminum Industry and will participate in the subsequent applications.

Pricing

The PRC government does not impose any limitations with respect to the pricing of alumina, primary aluminum and related products. Thus, alumina and primary aluminum producers are free to set prices for their products. All the raw materials, supplemental materials and other supplies that we purchase are based on market prices. Freight transportation on the national railway system is subject to government mandated pricing.

Electricity Supply and Price

The National Energy Administration is responsible for the supervision and administration of the power industry in China. The NDRC and local governments regulate electricity pricing.

The Electric Power Law of China and related rules and regulations govern construction, generation, supply and consumption of electric power. Currently, China’s state-owned power companies, through their respective local subsidiaries, operate all the regional power grids in China from which we obtain a part of our electricity requirements. In October 2007, the PRC government issued “Notice on Further Solutions of the Difference in Electricity Rates,” according to which the preferential electricity prices originally enjoyed by Chinese primary aluminum enterprises have been gradually abolished. In December 2007, the PRC government issued “Notice of Eliminating Preferential Electricity Rate for High Energy Consuming Enterprises and Related Matters,” which further eliminated the preferential electricity price arrangement enjoyed by Chinese primary aluminum enterprises. In December 2013, the NDRC and MIIT issued the “Circular on the Policies for Tiered Pricing of Electricity Used by Electrolytic Aluminum Enterprises”, which became effective on January 1, 2014, to impose tiers of electricity prices on primary aluminum smelters. In March 2015, new policies and reforms relating to electricity generation, retail, usage, and other related sectors were introduced. Under “Several Opinions of the CPC Central Committee and the State Council on Further Deepening the Reform of the Electric Power System,” a series of reforms relating to electricity pricing, distribution and retail segments, electricity trading, distributed generation, and other aspects has been put forward. In November 2015, NDRC and the National Energy Administration of the PRC jointly issued further supplemental measures, including “Implementation Opinions on Promoting Transmission-Distribution Price Reform,” “Implementation Opinions on Promoting Power Market Construction,” “Implementation Opinions on Establishing Power Trading Institutions and Their Normative Operation,” “Implementation Opinions on Orderly Releasing Plans of Power Generation and Power Utilization,” “Implementation Opinions on Promoting Power-Sales Side Reform,” and “Guidance Opinions on Reinforcing and Regulating Supervision and Management of Coal-Fired Self-Generation Power Plants,” which set out further requirements and implementation steps in relation to the reform of electric power systems. Towards the end of 2016, NDRC promulgated “Measures of Electricity Pricing for Transmission-Distribution Grid at the Provincial Level,” which established a regulatory framework of electricity transmission and distribution pricing.

58

On August 26, 2021, NDRC further issued “Circular for Improvement of the Policies for Tiered Pricing of Electricity Used by Electrolytic Aluminum Enterprises,” which came into effect on January 1, 2022. It provides that if the comprehensive alternating current consumption of molten aluminum is not higher than 13,650 kWh per ton, the electricity price will not be increased. If power consumption exceeds 13,650 kWh per ton, the electricity price will be increased by RMB0.01 per kWh for every additional 20 kWh. The grading standard will be lowered to 13,450 kWh in 2023 and further to 13,300 kWh in 2025, in each case excluding power consumed in the desulfurization process. In addition, it prohibits implementation of any preferential electricity price policies in the electrolytic aluminum industry.

On October 11, 2021, NDRC issued “Notice on Further Deepening the Market Reform of the Feed-in Tariff for Coal-fired Power Generation, which requires the orderly liberalization of the feed-in tariff for all coal-fired power generation and the expansion of the fluctuation range of the market trading tariff, resulting in a significant increase in our cost of electricity. In order to reduce the impact of electricity price increase, we have been actively participating in market trading with power generation enterprises with cost advantages, while carrying out energy saving and consumption reduction at the same time.

Regulations Concerning Imports and Exports of Alumina and Primary Aluminum

Import taxes on alumina and primary aluminum have been eliminated. The export tariff on certain primary aluminum products has been 15% since August 1, 2007.

Environmental Protection Laws and Regulations

The Ministry of Ecology and Environment of China is responsible for supervision and administration of environmental protection in China. It formulates national environmental quality and discharge standards and monitors China’s environmental system. Bureau of Ecology and Environment at the municipal level or above is responsible for environmental protection within its jurisdiction.

The Law on Environment Impact Assessment and relevant regulations require each enterprise to file an environmental impact report with the relevant Bureau of Ecology and Environment for approval before undertaking the construction of a new production facility or any major expansion or renovation of an existing production facility. New facilities built pursuant to this approval are not permitted to operate until the relevant environmental bureau has performed an inspection and concluded that the facilities are in compliance with environmental standards.

The Environmental Protection Law requires any facility that produces pollutants or other hazards to incorporate environmental protection measures in its operations and establish an environmental protection responsibility system. Such system includes adoption of effective measures to control and properly dispose of waste gases, waste water, waste residue, dust or other waste materials. Any entity that discharges pollution must register with the relevant environmental protection authority. Regulations on the Administration of Pollutant Discharge Permits became effective on March 1, 2021, pursuant to which enterprises that discharge pollutants need to obtain permits from relevant environmental authorities in accordance with the regulations.

Penalties for breaches of the Environmental Protection Law include warning, payment of damages and imposition of fines. Any entity undertaking a construction project that fails to install pollution prevention and control facilities in compliance with environmental standards for a construction project may be ordered to suspend production or operations or to cease operations and may be fined. Criminal liability may be imposed for a material violation of environmental laws and regulations that causes any significant loss of property or personal injuries or death.

On December 25, 2016, the PRC government promulgated the Environmental Protection Tax Law, which became effective from January 1, 2018 and was amended on October 26, 2018. The Environmental Protection Tax Law imposes environmental protection tax to enterprises, entities, producers or operators that discharge taxable pollutants into air, water or lands. Taxable pollutants include air pollutants, water pollutants, solid wastes and noises. The environmental protection tax is collected by the tax authority and levied in accordance with a table attached to the Environmental Protection Tax Law. However, emission of taxable pollutants into the centralized sewage and domestic waste treatment facilities, or storage or disposal of solid wastes in facilities or places that meet the national or local environmental protection standard, by enterprises, entities, producers or operators, is not deemed as direct emission of pollutants into the environment and is exempted from the environmental protection tax for such pollutants.

59

In April 2020, the PRC government promulgated the amended Law on Prevention and Control of Environmental Pollution Caused by Solid Waste. Effective on September 1, 2020, the amended law imposes stricter responsibilities on the entities that generate industrial solid waste for environmental pollution caused by industrial solid waste. For example, under the revised version, if an entity that generates industrial solid waste engages a third-party contractor to deliver, use or dispose such industrial solid waste, it shall verify the qualification of such third-party contractor and enter into an agreement with such third party on requirements for the environment pollution prevention, failing which the entity will be jointly liable for any damages to the environment caused by the third-party contractor in relation to such arrangement. In conjunction with the amendment of the Law on Prevention and Control of Environmental Pollution Caused by Solid Waste, the National Catalogue of Hazardous Wastes was revised in November 2020, which amended and reclassified some hazardous wastes.

Mineral Resources Laws and Regulations

All mineral resources in China are owned by the state under the current Mineral Resources Law. Exploration, exploitation and mining operations must comply with the relevant provisions of the Mineral Resources Law and are under the supervision of the Ministry of Natural Resources. Exploration and exploitation of mineral resources are also subject to examination and approval by the Ministry of Natural Resources or relevant local authorities. Upon approval, the relevant administrative authorities, which are responsible for supervision and inspection of mining exploitation in their jurisdiction, will issue an exploration permit or mining permit. The holders of mining rights are required to file with the relevant administrative authorities annually.

The PRC government permits mine operators of collectively owned mines to exploit mineral resources in designated areas and individuals to mine scattered mineral resources. Such mine operators and individuals are subject to government regulation. Mining activities by individuals are restricted. Individuals are not permitted to exploit mineral reserves allocated for exploitation by a mining enterprise or company, or specified minerals prescribed by the state for protective mining. Indiscriminate mining that damages mineral resources is prohibited.

If mining activities result in damage to arable land, grassland or afforested area, the mining operator must take measures to return the land to an arable state within the prescribed time frame. Any entity or individual which fails to fulfil its remediation obligations may be fined and denied application for land use rights for new land by the relevant land and natural resources authorities.

It is unlawful for an entity or individual to conduct mining operations in areas designated for other legal mining operators. A mining operator whose exploitation causes harm to others in terms of production or in terms of living standards is liable for compensation and is required to take necessary remedial measures. When a mine is closed, a mine closure report and information concerning the mining facilities, hidden dangers, remediation and environmental protection must be submitted for examination and approval in accordance with the relevant PRC law and regulations.

Mineral products that have been illegally extracted and the related income derived from such activities may be confiscated and may result in fines, revocation of the mining permit and, in serious circumstances, criminal liability.

Energy Conservation Law

The amended Energy Conservation Law came into effect on October 26, 2018. It sets out the general principles for reducing energy waste and improving efficiency of energy consumption. It urges the adjustment of industry structure and replacement of high energy consumption projects with new energy or renewable energy resources. It provides that an energy conservation assessment and review system shall apply to new investment projects and where a project does not meet the mandatory energy conservation standards, the project cannot be constructed. If a project that does not meet the mandatory energy conservation standards has been completed, it cannot be put into use.

In March 2014, the MIIT issued a regulation, the “Opinion on Implementing Supervision of Industrial Energy Conservation,” which lists the primary aluminum smelting as one of the high energy consumption operations that will be strictly monitored. In December 2014, the MIIT issued the Guidance for National Industrial Efficiency, which sets forth industrial efficiency standards for producers of major products in industries that involve high energy consumption, which included primary aluminum and alumina products.

The State Council issued the Working Guidance for Carbon Dioxide Peaking and Carbon Neutrality in Full and Faithful Implementation of the New Development Philosophy on September 22, 2021. It sets China’s main objective for energy consumption per unit of GDP and carbon dioxide (CO₂) emissions per unit of GDP for 2025, 2030 and 2060. It predicts that by 2060, China will reach carbon neutrality.

Regulations Concerning Electrolytic Aluminum Industry

In June 2016, the General Office of the State Council promulgated “Guiding Opinions on Creating a Favorable Market Environment and Promoting the Non-Ferrous Metals Industry to Adjust Structure, Advance Transformation and Increase Efficiency,” under which the construction of new electrolytic aluminum projects and the reconstruction or expansion of existing electrolytic aluminum projects would be approved only if such construction, reconstruction or expansion would introduce new electrolytic aluminum production capacity in an amount equal to or smaller than the amount of existing electrolytic aluminum production capacity to be replaced by such construction, reconstruction or expansion.

In April 2017, NDRC, MIIT, the Ministry of Land and Resources (now known as the Ministry of Natural Resources) and the Ministry of Environmental Protection (now known as the Ministry of Ecology and Environment) jointly issued the “Notice Regarding the Plan on Special Action for Clean-up and Rectification of Projects in Violation of Laws and Regulations in the Electrolytic Aluminum Industry,” which sets forth a comprehensive plan to inspect electrolytic aluminum projects and rectify violations of applicable laws or regulations revealed in the inspection.

On January 1, 2018, MITT issued the “Notice Regarding Electrolytic Aluminum Enterprises to Realize Capacity Replacement by Acquisition, Merger and Restructure,” which requires electrolytic aluminum enterprises to achieve capacity replacement by acquisition, merger or capacity transferring and exchange of capacity quotas with its group companies.

Tax Laws and Regulation

In March 2007, the PRC government promulgated the Enterprise Income Tax Law which became effective from January 1, 2008 and was revised in 2018. The Enterprise Income Tax Law imposes a single income tax rate of 25% on both domestic and foreign invested enterprises. Pursuant to the Enterprise Income Tax Law, important high- and new-tech enterprises that are necessary to be supported by the state are subject to a reduced enterprise income tax rate of 15%. Certain branches and subsidiaries of us were granted tax concessions including preferential tax rates of 15%. On December 6, 2007, the PRC government promulgated the Enterprise Income Tax Law Implementation Rules which also became effective on January 1, 2008 and was later revised in 2019.

In March 2016, the MOF and the SAT jointly promulgated “Circular on Comprehensively Promoting the Pilot Program of the Collection of Value-added Tax in Lieu of Business Tax,” pursuant to which we are allowed to deduct input tax from output tax according to the amount set forth in the special value-added tax invoices obtained from our purchases of services, intangible assets or real estate. On April 4, 2018, the MOF and the SAT issued the Circular on Adjusting Value-added Tax Rates, which became effective on May 1, 2018. Pursuant to this circular, for sale or import of goods, the previous applicable value-added tax rates of 17% and 11% were adjusted to 16% and 10%, respectively.

On March 20, 2019, the MOF, the SAT and the General Administration of Customs jointly issued the Announcement on Policies for Deepening Reform of Value-added Tax, which became effective on April 1, 2019. Pursuant to this announcement, for sales or import of goods by a general taxpayer that were previously subject to value added tax at the rate of 16%, the applicable tax rate has been adjusted to 13%, and for those previously subject to value added tax at the rate of 10%, the applicable tax rate has been adjusted to 9%.

Bauxite Mines and Coal Mines

For summary disclosure of our bauxite mines and coal mines, please refer to “– B. Business Overview – Our Mines.”

Boffa Mine

In accordance with the requirements of Regulation S-K 1300, we consider our Boffa mine in Guinea as the sole mining property that is material to our business. We have engaged Mr. Shengfa Tu as the qualified person for our bauxite mines. Mr. Tu has prepared the Technical Report Summary for our Boffa mine in compliance with Regulation S-K 1300 and Item 601(b)(96) of Regulation S-K, filed as Exhibit 96.1 to this annual report.

The information that follows relating to our Boffa mine is derived, for the most part, from the Technical Report Summary. Portions of the following information are based on assumptions, qualifications, and procedures that are not fully described herein. Reference should be made to the full text of the Technical Report Summary.

63

Location, Infrastructure and Facilities

The following map sets forth details of the area surrounding our Boffa mine in Guinea:

The Boffa mine is located eight kilometers north east of Boffa, the capital of Boffa Prefecture in Guinea. The linear distance between Boffa mine and Conakry, the capital of Guinea, is approximately 86 kilometers and the linear distance between the southwest corner of Boffa mine and the Atlantic Ocean is 25 kilometers. Conakry is connected to the city Boffa by the N3 road, which is a tarmac road with a distance of approximately 150 kilometers and a width of approximately six meters. The southern part of the Boffa mine is connected to the N3 road by a hasty road with a distance of approximately five kilometers. The Boffa mine consists of Boffa north area and Boffa south area, which covers an area of 653.55 km² and 594.61 km², respectively.

There are two main railways in Guinea. One railway links Conakry and the Fria smelter east of Boffa. The other railway runs from the CBG mine near Sangaredi to the port of Kamsar and has a larger transport capacity.

Guinea has two major ports. The first is the port of Conakry, adjacent to Conakry. The port handles container shipments and exportation of alumina and bauxite. The second port is Kamsar CBG, which is primarily used to export bauxite and has two smaller terminals for other bulk cargoes.

The Boffa mine is open pit, equipped with 2500SM open pit mining machines. We have facilities such as mining industrial sites, raw ore storage yards, low-grade ore storage yards, open-pit mining machines, belt conveyor systems, bridges, inland terminals, electric power stations and a temporary dump site. It has transportation facilities that have access to local roads and a belt conveyor system. Our mining facilities in the Boffa mine are connected to the electric power stations, which are powered by heavy oil fuel. Most of the facilities started to operate since Boffa mine was put into operation in April 2020. The quality of groundwater in the Boffa mine area meets the requirements for drinking, and the production and domestic water in the mine area is extracted groundwater. We believe all of our equipment in the Boffa mine is in good physical condition and suitable for our operations. The total book value of Boffa mine’s fixed assets is RMB1.698 billion as of December 31, 2021.

64

History, Mining Rights and Operations

From August 2005 to May 2006, 10 exploration leases were granted to BHP Billiton in Guinea, which cover Boffa. In 2008 and 2011, BHP Billiton applied to the Guinea Government to reduce the size of the mine covered by the leases. In 2012, BHP Billiton submitted “Boffa Santou Houda Project Close Out Report” to the Guinea Government and handed the exploration leases back to the Guinea Government.

On October 31, 2016, Chalco signed cooperation framework agreements with the Guinea Government and Guinean State Mining Company for the development of the Boffa mine. On June 8, 2018, Chalco Hong Kong and Chalco Guinea Company S.A., a wholly-owned subsidiary of Chalco Hong Kong, entered into a mining convention with the Guinean government, pursuant to which Chalco Hong Kong agreed to provide investment funds while the Guinean government agreed to provide mining licenses and rights to transport mining products for the development and operation of the Boffa Project. On July 9, 2018, the president of Guinea signed a decree to grant both Boffa north area and Boffa south area a mining permit, effective from July 2018 to July 2033. For more details of the history of Boffa mine, please refer to “Item 4. Information on the Company – A. History and Development of the Company – Boffa Project.”

Upon expiration of the current 15-year period, our mining permit for the Boffa mine is renewable for additional periods, each of which would also be 15 years except that the last renewal period would be subject to the depletion timing of the Boffa mine. We will not need to pay additional consideration for each renewal of the mining permit. The Boffa Project commenced construction in September 2018 and was completed and put into operation in April 2020. We must pay a royalty of US$0.208 per tonne based on the volume of bauxite extracted from the Boffa mine.

Chalco Guinea Company S.A. has 620 employees. From then through the end of 2021, we extracted approximately 20.4 million tonnes of bauxite from the Boffa mine. The annual bauxite output capacity is expected to increase to 15 million tonnes in 2022.

As of the date of this annual report, we have not been found any violation or subject to any fine for our mining operations at the Boffa mine.

A.Operating Results

Overview

We are a leading enterprise in the non-ferrous metal industry in China. We are engaged principally in alumina refining, primary aluminum smelting, and trading of non-ferrous metal products, coal products and other products. In addition, we are engaged in coal mining and power generation. The remainder of our revenues was derived from research and development activities and other products and services. We organize and manage our operations according to the following key segments:

● Our alumina segment, which consists of the mining and purchasing of bauxite and other raw materials, and production and sale of alumina as well as chemical alumina. Alumina accounted for approximately 93.1% of the total production volume for this segment in 2021. Chemical alumina products are used in the production of chemical, pharmaceutical, ceramic and construction materials. In the process of refining bauxite into alumina, we produce gallium as a by-product, which is a rare, high-value metal with applications in the electronics and telecommunication industries.

67

● Our primary aluminum segment, which consists of the procurement of alumina, other raw materials, supplemental materials and electrical power, the production and sale of primary aluminum and aluminum-related products, such as carbon products, aluminum alloy products and other aluminum products. Our principal primary aluminum products are ingots, molten aluminum and aluminum alloys, which accounted for approximately 18.6%, 44.1% and 37.3%, respectively, of our total production volume of primary aluminum in 2021. Our standard 20 kilogram remelt ingots are used for general aluminum fabrication in the construction, electricity, electronics, transportation, packaging, machinery and durable goods industries. We internally produce substantially all the carbon products used at our smelters and sell our remaining carbon products to external customers.

● Our trading segment, which mainly consists of the trading of alumina, primary aluminum, aluminum fabrication products, other non-ferrous metal products, and crude fuels such as coal products, as well as supplemental materials and logistics and transport services to our internal manufacturing plants and external customers. We established our trading business under Chalco Trading as a separate segment in July 2010 as a result of our operational structural adjustment. Since 2014, we have established Chalco Materials, Chalco Logistics and Chalco Trading Group to continuously promote and deepen development of our trading business, jointly constituting our trading segment. Established in 2018, Chalco Trading Group has undertaken the businesses that used to be operated by Chalco Trading.

● Our energy segment, which consists of the research and development, production and operation of energy products, including coal mining and conventional coal-fire power generation as well as renewable energy generation such as wind power and solar power. We are also engaged in new energy equipment production. We established our energy segment in January 2013 as a result of our acquisition of Ningxia Energy in line with our development strategy to partially offset our future energy costs. In 2021, we supplied the majority of the electricity we generated for our own production use, supplied a portion of the coal output to our own electric power plant and sold the remaining portion to external customers. Ningxia Energy supplied the electricity it generated mainly to the state grid in China.

● Our corporate and other operating segment, which consists of corporate and other aluminum-related research, development, and our other activities.

Our consolidated revenue increased by 45.0% from RMB185,990.6 million for the year ended December 31, 2020 to RMB269,748.2 million for the year ended December 31, 2021, primarily due to the year-on-year increase in the prices of alumina and electrolytic aluminum. Our net profit increased significantly from RMB1,599.2 million for the year ended December 31, 2020 to RMB7,789.0 million for the year ended December 31, 2021, primarily because our gross profit increased significantly from RMB12,316.3 million in 2020 to RMB26,478.3 million in 2021.

Factors Affecting Our Results of Operations

We believe that the following factors, which impact our various revenue and expense items (as described below), have had, and will continue to have, a significant effect on the development of our business, financial position and results of operation.

Economic Condition of China and the World

As the major aluminum product market is globalized, the demand for and prices of our products are highly correlated with the general economic condition of China and the world and the performance of the major aluminum and related product markets. In recent years, China’s economy continued to experience growth despite the negative effects of the global financial crisis beginning in the second half of 2008 and economic recession in 2009, as well as general market volatility and changing macroeconomic conditions. However, as China is in the process of transforming its development model, optimizing its economic structure and changing its growth drivers, the growth of China’s economy has slowed down since 2014, with GDP growth from 2014 through 2019 ranging from 6.1% to 6.9%. Furthermore, the outbreak and global spread of the COVID-19 in 2020 and 2021 has adversely affected the global economy and China’s economy and financial market in general. As a result, the compound annual GDP growth rate of China was 5.1% in 2020 and 2021. Please refer to “Item 3. Key Information – D. Risk Factors – Our business may be materially and adversely affected by the COVID-19 pandemic” for further details of the impact of the outbreak of COVID-19.

68

The global output of alumina (with chemical alumina products included) in 2021 increased by approximately 4.2% from 2020 to approximately 138.66 million tonnes. The global alumina consumption (with chemical alumina products included) in 2021 increased approximately by 3.6% from 2020 to approximately 137.61 million tonnes. In 2021, the domestic output of alumina (with chemical alumina products included) increased approximately by 5.9% from 2020 to approximately 75.20 million tonnes and the domestic consumption for alumina (with chemical alumina products included) increased by approximately 4.3% from 2020 to approximately 77.99 million tonnes.

The global output of primary aluminum in 2021 increased by approximately 3.8% from 2020 to approximately 67.78 million tonnes. The global consumption of primary aluminum in 2021 increased by approximately 9.1% from 2020 to approximately 69.15 million tonnes. In 2021, the domestic output of primary aluminum decreased by approximately 4.3% from 2020 to approximately 38.90 million tonnes and the domestic consumption of primary aluminum increased by approximately 5.7% from 2020 to approximately 40.55 million tonnes.

Mix and Pricing of Our Products

We are engaged principally in alumina refining, primary aluminum smelting and sales of these products and trading of non-ferrous metal products and other products. In addition, we are engaged in coal mining and power generation. We coordinate substantially all of our sales and marketing activities for our self-produced alumina products and some of our sales and marketing activities for our self-produced primary aluminum products through Chalco Trading Group, taking into account the spot market prices and SHFE prices. In 2021, revenues generated from alumina, primary aluminum, trading and energy segments (after elimination of inter-segment sales) accounted for 6.9%, 23.7%, 66.4% and 2.8%, respectively, of our consolidated total revenues after elimination of inter-segment sales. We apply different policies to price different products. For information on our pricing of different products, please see the section headed “Item 4. Information of the Company – B. Business Overview – Sales and Marketing.”

The sales prices of alumina that our alumina refineries sell internally to Chalco Trading Group are determined based on our budgeted sale prices, spot market prices and the prices of primary aluminum on SHFE. Chalco Trading Group coordinates the external negotiation and execution of sales contracts of our alumina products. The alumina prices in both the domestic and international markets increased in 2021 when compared to that of 2020. The increase in the alumina price in the international market was attributable to the gradual recovery of the demand of alumina after the COVID-19 outbreak in 2020 and the globally strained supply chain due to reduced production capacity. In 2021, the spot price of alumina in the international market reached a high of approximately US$483 per tonne and bottomed out at approximately US$269 per tonne. The average spot price of alumina in the international market was approximately US$330 per tonne, representing an increase of 21.5% from 2020. The spot price of alumina in the domestic market reached a high of RMB4,108 per tonne and bottomed out at RMB2,324 per tonne. The average spot price of alumina in the domestic market was approximately RMB2,799 per tonne, representing an increase of 19.8% from 2020. The increase of the alumina price in the domestic market was primarily attributable to the maintenance of the high price of electrolytic aluminum that drove increased price of alumina, the decrease in supply of alumina in the domestic market due to government inspection of environment and government control of energy and consumption, declining imports of alumina due to a decrease in supply of alumina in the international market, and an increase in prices of raw materials for alumina. Our average selling price of alumina increased by 13.4% from RMB2,465 per tonne in 2020 to RMB2,785 per tonne in 2021.

Like most primary aluminum producers in China, we price our primary aluminum products by reference to the primary aluminum spot prices and futures price on the SHFE. In 2021, the primary aluminum prices in the international market generally increased due to the ease of global liquidity and the gradual recovery of the demand of alumina after the COVID-19 outbreak in 2020. The change of primary aluminum prices in the domestic market in 2021 was attributable to the ease of global liquidity, the unmet demand of primary aluminum due to government control of energy and consumption, electricity power rationing, benefits from the policy of “carbon dioxide peaking and carbon neutrality” and increase in prices of raw materials for primary aluminum. In 2021, three-month aluminum futures prices reached a high of US$3,229 per tonne and a low of US$1,945 per tonne on LME; and a high of RMB24,820 per tonne and a low of RMB14,640 per tonne on SHFE. In 2021, the average price of spot aluminum and three-month aluminum futures at LME were approximately US$2,480 per tonne and US$2,485 per tonne, respectively, representing an increase of 45.5% and 43.3% from that of 2020, respectively. The average three-month aluminum futures prices at SHFE increased by 37.3% from RMB13,807 per tonne in 2020 to RMB18,898 per tonne in 2021 while the average spot prices of primary aluminum at SHFE increased by 34.2% from RMB14,112 per tonne in 2020 to RMB18,953 per tonne in 2021. Our average selling price of primary aluminum increased by 34.8% from RMB14,142 per tonne in 2020 to RMB19,099 per tonne in 2021.

Price Volatility of Non-ferrous Metal and Coal Products

Since late 2009, as a result of the implementation of our operational structural adjustment, we have been engaged substantially in the trading of outsourced non-ferrous metal products to increase our profit. In 2012, we began to engage in the trading of significant amounts of outsourced coal products to diversify our product portfolio. Although the profit margin of sales of outsourced products is typically lower than that of our self-produced products, we generated substantial revenues and profit from the trading of outsourced products during the past few years due to our significant trading volumes. Our revenue generated from external sales of products purchased from external sources in 2021 was approximately RMB151,105.6 million, representing approximately 84.3% of total revenue from external sales in our trading segment. From time to time, we may enter into futures and option transactions in addition to the simple buy-low-sell-high trading model to hedge against price fluctuations in the non-ferrous metal and coal products market. However, short-term price volatility of these products remains a key factor affecting our operating results, as we need to make the correct prediction concerning the price trends of these products on the markets to ensure substantial revenues through large trading volume. If the market price trend does not match our prediction, we may be forced to sell trading products at low prices or to purchase trading products at high prices, which may adversely affect gross margins and profitability.

Manufacturing Costs

Our cost of revenues consists primarily of the costs of raw materials, overhead cost and electric power cost. Our principal raw material is bauxite. For the years ended December 31, 2019, 2020 and 2021, bauxite supplied by our mines accounted for 37.6%, 46.4% and 63.5%, respectively, of our total bauxite used in the production of alumina. The unit cost of bauxite produced by us is generally lower than the unit cost of bauxite procured from external suppliers. In 2021, the average purchase price of bauxite per tonne from our other suppliers decreased by approximately 6.2% to RMB386.83 while the average cost of bauxite per tonne from our own mines increased by approximately 6.3% to RMB299.03 compared to 2020. In addition, our average purchase price per unit tonne of thermal coal in 2021 increased by approximately 52.4% compared to 2020. As a result, our average cost of alumina per tonne in 2021 increased by approximately 2.5% from that in 2020.

Primary aluminum is one of our major aluminum products and is produced by smelting operations. Smelting operations require a substantial and continuous supply of electricity. Electricity cost is the most significant component of our primary aluminum production cost and accounted for approximately 37.0% of our unit production cost for primary aluminum in 2021. The availability and price of electricity are key considerations in our primary aluminum operations. Interruptions of electricity supply can result in lengthy production shutdowns, increased costs associated with restarting production and waste of production in progress, and prolonged interruptions can cause damage to, or the destruction of, production equipment and facilities. Our average annual electricity price per kWh (including tax) remained relatively stable from 2019 to 2020 and increased by 27.0% from 2020 to 2021.

Given our high proportion of fixed costs, we must generate sufficient sales to absorb our fixed costs to maintain or increase our operating margins. Our acquisitions and production expansion in recent years have significantly increased our costs that are relatively fixed in nature, such as leases and depreciation of property, plant and equipment and employee benefit expenses. If we are able to maintain satisfactory facility utilization rates and productivity, our production capacity expansion will enable us to reduce our unit costs through economies of scale and recover associated increased costs through higher output. In 2021, we continued to focus on lowering production costs and increasing production efficiency through reducing raw material consumption by improving technology and internal management.

Availability and Costs of Financing

We require a significant amount of capital to fund our operations. For example, we need substantial amounts of funds for expanding our operations, purchasing and maintaining equipment and procuring commodities. We have in the past funded our capital expenditures primarily with bank loans and the issuance of medium-term notes and bonds and long-term bonds. The availability of financing is subject to various factors, including our credit history and the prevailing credit policy adopted by the PRC government. Over the years, we have maintained good relationships with the commercial banks in China, which enables us to access bank financing at relatively low costs. Any change of lending policies adopted by the PRC government in the future may, among other things, affect our ability to obtain financing and may in turn adversely affect our operating results.

Our finance costs decreased by 10.8% from 2020 to 2021, primarily because we reduced the scale of our interest-bearing debts and the unit cost of financing decreased in 2021. If we are unable to secure sufficient external funding when required, we may not be able to fund our working capital requirements and necessary capital expenditures, which could adversely affect our business, financial performance and prospects.

70

In addition, our borrowing costs and access to debt financing depend significantly on our credit ratings. These ratings, including long-term corporate credit ratings and financing bond credit ratings, are assigned by rating agencies, which may lower or withdraw their ratings. Any change in our credit ratings or average interest rate could have negative implications, which may increase our finance costs and affect our financial results.

Regulatory Environment

The PRC government continues to shape the structure and development of the aluminum industry through industry guidelines for energy conservation, safety, environmental and quality. The central and local PRC government will give more support to entities that meet the standards in such industry guidelines. If the PRC government changes its current industry guidelines or the interpretation of those industry guidelines, we may face pressure on profit margins and constraints on our ability to expand our business operations.

Selected Statement of Operation Items

Revenue

Our revenue is primarily generated from sales of alumina, primary aluminum, other non-ferrous metal products and coal products. In addition, we are engaged in coal mining and power generation. The remainder of our revenues was derived from research and development activities and other products and services.

Cost of Sales

Our cost of sales consists primarily of the purchase of inventories in relation to trading activities, cost of raw materials, consumables and electric power used in manufacturing, certain fixed cost and employee benefit expenses. For the years ended December 31, 2019, 2020 and 2021, our cost of sales was RMB179,284.0 million, RMB173,674.2 million and RMB243,269.9 million, respectively, and accounted for 94.3%, 93.4% and 90.2%, respectively, of the total consolidated revenues for those periods.

Operating Expenses

Selling and Distribution Expenses. Our selling and distribution expenses consist primarily of transportation and loading expenses which are indirectly related to product sales and employee benefit expenses for employees in selling and distribution department. Selling and distribution expenses accounted for 7.7%, 4.3% and 2.7% of our total operating expenses for the years ended December 31, 2019, 2020 and 2021, respectively.

General and Administrative Expenses. Our general and administrative expenses consist primarily of employee benefit expenses for directors and officers and employees in the administrative department and, to a lesser extent, taxes other than income tax expenses, depreciation of non-production property, plant and equipment, termination benefit expenses, travelling and entertainment, legal and other professional fees, amortization of right-of-use assets, utilities and office supplies, insurance expense, repairs and maintenance expenses, auditors’ remuneration, amortization of intangible assets, and others. General and administrative expenses accounted for 68.6%, 56.9% and 44.9% of our total operating expenses for the years ended December 31, 2019, 2020 and 2021, respectively. Employee benefit expenses, including salaries and bonus, housing fund, staff welfare and other expenses, employment expense in relation to early retirement schemes and termination benefit, comprise a significant component of our general and administrative expenses, accounting for 46.3%, 41.2% and 43.0% of our total general and administrative expenses for the years ended December 31, 2019, 2020 and 2021, respectively.

Research and Development Expenses. Our research and development expenses accounted for 16.2%, 19.6% and 20.4% of our total operating expenses for the years ended December 31, 2019, 2020 and 2021, respectively.

Impairment Loss on Property, Plant and Equipment. Our impairment loss on property, plant and equipment accounted for 4.5%, 5.7% and 20.1% of our total operating expenses for the years ended December 31, 2019, 2020 and 2021, respectively. The increase in impairment loss on property, plant and equipment in 2021 was primarily because some of our assets are not in operation, temporarily idle or not operated with full capacity due to production plan adjustments, the increase in cost of mining resulting from environmental protection requirements and the increase in operating cost including rents.

Impairment Losses on Financial Assets. Our impairment losses on financial assets accounted for 11.9% of our total operating expenses for the year ended December 31, 2021.

71

Impairment Losses on Investments in Joint Ventures. We did not incur any impairment losses on investments in joint ventures for the year ended December 31, 2021.

Other Income

Our other income consists primarily of tax rebates and grants on industrial development support from the government. For the year ended December 31, 2021, our other income was RMB148.4 million and accounted for approximately 0.1% of the total consolidated revenues.

Other Losses, net

Our net other losses consisted primarily of losses on disposal of property, plant and equipment and losses from closing out hedging futures. For the year ended December 31, 2021, our net other losses were RMB1,623.5 million and accounted for approximately 0.6% of the total consolidated revenues.

Finance Income

Our finance income consists primarily of interest income. For the year ended December 31, 2021, our finance income was RMB276.0 million and accounted for approximately 0.1% of the total consolidated revenues.

Finance Costs

Our financing costs consist primarily of interest expense on our borrowings and bonds, interest on lease liability and amortization of unrecognized finance expenses. Interest rates on loans related to capital expenditures and working capital set by banks generally follow guidelines issued by the PBOC. The PBOC regulates the interest rates for commercial loans charged by state-owned banks from time to time as part of the PRC government’s efforts to regulate the PRC economy. In 2021, we incurred interest expense (net of capitalized interest) of RMB3,520.5 million on our borrowings.

Share of Profits and Losses of Joint Ventures

Our share of profits and losses of joint ventures is the profit attributable to us from our joint ventures, based on our equity interests in such joint ventures. A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

Share of Profits and Losses of Associates

Our share of profits and losses of associates is the profit attributable to us from our associates, based on our equity interests in such associates. An associate is an entity over which we have significant influence but not control.

Revenue from internal sales of the trading segment increased by 7.8% from RMB27,877.2 million for the year ended December 31, 2019 to RMB30,058.1 million for the year ended December 31, 2020, primarily due to the increase in the internal trading of alumina and bauxite.

Cost and expenses. The total cost and expenses for our trading segment decreased by 2.0% from RMB157,977.7 million for the year ended December 31, 2019 to RMB154,810.3 million for the year ended December 31, 2020, primarily due to the decrease by 70.7% in the cost for trading of zinc ingots and the decrease by 58.4% in the cost for trading of coking coal in 2020, as compared to those in 2019, partially offset by the increase by 16.2% in the cost for trading of aluminum ingots in 2020, as compared to that in 2019.

Segment results. Our segment profit decreased by 39.2% from RMB958.0 million for the year ended December 31, 2019 to RMB582.1 million for the year ended December 31, 2020. This was mainly due to the decrease in the import volume of coking coal as affected by the COVID-19 pandemic.

Energy Segment

Revenues. Total revenue generated by the energy segment decreased by 2.2% from RMB7,346.0 million for the year ended December 31, 2019 to RMB7,184.2 million for the year ended December 31, 2020, primarily due to the decrease in coal prices.

Revenue from external sales of the energy segment decreased by 2.4% from RMB7,109.8 million for the year ended December 31, 2019 to RMB6,940.4 million for the year ended December 31, 2020, primarily due to the decrease in coal prices.

Revenue from internal sales of the energy segment increased from RMB236.1 million for the year ended December 31, 2019 to RMB243.8 million for the year ended December 31, 2020, remaining relatively stable.

Cost and expenses. The total cost and expenses for our energy segment increased by 2.4% from RMB6,942.5 million for the year ended December 31, 2019 to RMB7,107.0 million for the year ended December 31, 2020, primarily because we had gains on disposal of associates while we did not have such disposal in 2020.

Segment results. We recorded a segment loss of RMB77.2 million for the year ended December 31, 2020, whereas we had a segment profit of RMB403.5 million for the year ended December 31, 2019. This was primarily due to the decrease in the price of the coal during the year. In addition, we had gains on disposal of associates in 2019 while we did not have such disposal in 2020.

Corporate and Other Operating Segment

Revenues. Revenue from the corporate and other operating segment decreased by 8.8% from RMB492.9 million for the year ended December 31, 2019 to RMB449.6 million for the year ended December 31, 2020, primarily due to the decrease in business of an engineering company in this segment.

Segment results. We recorded a segment loss of RMB1,705.2 million for the year ended December 31, 2020, representing an increase of 72.6% from a segment loss of RMB987.7 million for the year ended December 31, 2019. This was mainly because we had gains from our investment in Yunnan Aluminum and Yixin Aluminum in 2019 and we made provision for impairment losses of certain long aging receivables in 2020.

B.Liquidity and Capital Resources

Historically, our primary sources of funding have been cash generated from operating activities, prepayments and deposits from customers, bank and other loans and proceeds from equity or notes and bonds offerings. Our primary uses of funds have been working capital for production, capital expenditures and repayments of short-term, medium-term and long-term borrowings.

As of December 31, 2021, our current assets amounted to RMB48,714.0 million, representing an increase of 5.3% from RMB46,268.6 million as of December 31, 2020, primarily due to the increase in monetary funds resulting from the increase in cash inflows from operations. As of December 31, 2021, our restricted cash and time deposits and cash and cash equivalents balance amounted to RMB19,178.0 million, representing an increase of 78.8% from RMB10,727,5 million as of December 31, 2020. As of December 31, 2021, our trade and notes receivable amounted to RMB6,904.9 million, representing a decrease of 25.9% from RMB9,313.6 million as of December 31, 2020.

As of December 31, 2021, our current liabilities amounted to RMB52,180.8 million, representing a decrease of 16.7% from RMB62,633.0 million as of December 31, 2020. This is mainly due to our efforts to optimize the maturity profile of the liabilities and minimize the scale of short-term interest-bearing loans and borrowings.

As of December 31, 2021, our net current liabilities amounted to RMB3,466.7 million, representing a decrease of 78.8% from RMB16,364.4 million as of December 31, 2020. As of December 31, 2021, our current ratio (current assets/current liabilities) was 0.93, compared with 0.74 as of December 31, 2020. Our quick ratio ((current assets – inventories – prepayments)/current liabilities) was 0.56 as of December 31, 2021, compared with 0.41 as of December 31, 2020.

82

We have considered our available sources of funds as follows:

● Our expected net cash inflows from operating activities in 2022;

● As of December 31, 2021, we had total banking facilities of approximately RMB128,100 million, of which RMB36,056 million had been utilized and unutilized banking facilities amounted to RMB92,044 million as of December 31, 2021, among which, banking facilities of approximately RMB25,530 million will remain unexpired over the 12 months from December 31, 2021. We are confident that all banking facilities can be renewed upon their expiration based on our past experience with banks and our good credit standing;

● Bond facilities registered with National Association of Financial Market Institutional Investors but not utilized; and

● Other available sources of financing from banks and other financial institutions based on our good credit history.

We believe that we have adequate resources to continue in operational existence for the foreseeable future not less than 12 months from December 31, 2021. The Board therefore continues to adopt the going concern basis in preparing our financial statements included in this annual report.

We recorded net cash flows used in investing activities of RMB13,395.8 million for the year ended December 31, 2019. The net cash flows generated from investing activities in 2020 were primarily due to the decrease in the financial products held by us and the decrease in our investment in project construction.

Senior Perpetual Capital Securities

Please refer to “Item 4. Information on the Company – A. History and Development of the Company – Senior Perpetual Capital Securities Offering” for further details.

Restriction on Cash Dividends

Our PRC subsidiaries are required to set aside a certain amount of their retained profits each year, if any, to fund certain statutory reserves and these reserves may not be distributed as cash dividends. In addition, when our subsidiaries incur debts on their own behalf, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us. Our directors are of the view that we will continue to be able to meet our borrowing payment obligations as they fall due from cash generated from our operating activities.

Capital Expenditures and Capital Commitments

The following table sets forth our capital expenditures for the years ended 2019, 2020 and 2021, and the capital expenditures of each segment as a percentage of our total capital expenditures for the periods indicated:

In 2021, we spent approximately RMB4,652.8 million of our capital expenditures (excluding equity interest investments) primarily in investments in construction, transformation and upgrading of projects, energy saving and consumption reduction, environmental governance, resources acquisition and technological research and development. Our total capital expenditures increased slightly from 2020 to 2021.

We expect our estimated capital expenditures in 2022 to be a total of approximately RMB6.8 billion, primarily for infrastructure and technology upgrading.

As of December 31, 2021, our Group’s contractual but not provided capital commitment to fixed assets investment amounted to RMB1,375.4 million.

As of December 31, 2021, our commitments to make capital contribution to our associates and joint ventures amounted to RMB441.8 million, comprised of the capital contributions of RMB400 million to Chinalco Overseas Development Co., Ltd., RMB8 million to Loudi Zhongyu New Materials Co., Ltd., RMB28 million to Shanxi Qinlv Taiyue New Materials Co., Ltd. and RMB6 million to Chinalco Tendering Company Limited, respectively.

We expect to use primarily operating cash flow in meeting such commitments with the shortfall to be satisfied by proceeds of bank loans, short-term and medium-term bonds and medium-term notes.

Off-Balance-Sheet Arrangements

There are no off-balance sheet arrangements material to investors that have or are reasonably likely to have a current or future effect on our financial condition, our changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources.

Our lease liabilities primarily relate to consideration for certain properties leased by us from Chinalco for the period commencing January 1, 2022.

Our loans and interest payables primarily consist of long-term bank and other loans, medium-term notes and bonds, short-term bonds and short-term bank and other loans.

The trade and notes payables are non-interest bearing and are normally settled within one year.

87

We intend to fund our existing and future material cash requirements with our existing cash and cash equivalents, bank loans, the issuance of medium-term notes and bonds and long-term bonds and other financing alternatives. We will continue to make cash commitments, including capital expenditures, to support the growth of our business.

The technology centers at our plants focus on providing solutions for specific issues of each plant and applying our developed technologies. Each of the plants also has opportunities to participate in operational testing and pilot industrialization relating to research and development of important and key technologies. We also collaborate with universities and other research institutions in China on some of our complicated projects.

D.Trend Information

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the period from January 1, 2021 to December 31, 2021, that are reasonably likely to have a material effect on our revenue, profitability, liquidity or capital resources, or that caused the disclosed financial information to be not necessarily indicative of future operating results or financial conditions.

E.Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with IFRS as issued by the International Accounting Standards Board, which requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the accounting policies. The areas in our financial reporting involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements, are disclosed in Note 3 to our consolidated financial statements. We have established procedures and processes to facilitate the making of such judgments in the preparation of our consolidated financial statements. Management has used the best information available but actual performance may differ from our management’s estimates and future changes in key variables could change future reported amounts in our consolidated financial statements.

Property, Plant and Equipment

Property, plant and equipment, other than construction in progress (“CIP”), are stated at cost less accumulated depreciation and any impairment losses. When an item of property, plant and equipment is classified as held for sale or when it is part of a disposal group classified as held for sale, it is not depreciated and is accounted for in accordance with IFRS 5. The cost of an item of property, plant and equipment comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use.

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the group and the cost of the item can be measured reliably. The carrying amount of any component accounted for as a separate asset is derecognized when replaced. All other repairs and maintenance are charged to profit or loss during the reporting period in which they are incurred.

We calculate depreciation using the straight-line method to allocate their cost or revalued amounts, net of their residual values, over their estimated useful lives as follows:

Buildings and infrastructure	8‑45 years
Machinery	3‑30 years
Transportation facilities	6‑10 years
Office and other equipment	3‑10 years

We reviewed and adjusted the assets’ depreciation method, residual values and useful lives, if appropriate, at least at each financial year end.

Construction in progress (“CIP”) represents buildings under construction, which is stated at cost less any impairment losses, and is not depreciated. Cost comprises the direct costs of construction and capitalized borrowing costs on related borrowed funds during the period of construction. CIP is reclassified to the appropriate categories of property, plant and equipment when completed and ready for use.

Gains and losses on disposals are determined by comparing proceeds with carrying amount. These are included in profit or loss.

Goodwill

Goodwill is measured as described in Note 2.3 to our consolidated financial statements. Goodwill on acquisitions of subsidiaries is included in intangible assets. Goodwill is not amortized but it is tested for impairment annually, or more frequently if events or changes in circumstances indicate that it might be impaired, and is carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill arose. The units or groups of units are identified at the lowest level at which goodwill is monitored for internal management purposes, being the operating segments.

Intangible assets - mining rights and mineral exploration rights

Our mineral exploration rights and mining rights relate to coal, bauxite and other mines.

(i)Recognition

Except for mineral exploration rights and mining rights acquired in a business combination, mineral exploration rights and mining rights are initially recorded at the cost which includes the acquisition consideration, qualifying exploration and other direct costs. The mineral exploration rights are stated at cost less any impairment, and the mining rights are stated at cost less any amortization and impairment.

(ii)Reclassification

Mineral exploration rights are converted to mining rights when obtain mining rights certification, or technical feasibility and commercial viability of extracting a mineral resource are demonstrable, and are subject to amortization when commercial production has commenced.

We assess the stage of each mine under construction to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the unique nature of each mine construction project. We consider various relevant criteria, such as completion of a reasonable period of testing of the mine and equipment, ability to produce in saleable form (within specifications) and ability to sustain ongoing production to assess when a mine is substantially complete and ready for its intended use.

(iii)Amortization

Mining rights other than coal mining rights are amortized on a straight-line basis over a shorter period of the mining right valid period and expected mining life. Estimated mineable periods of the majority of the mining rights range from 3 to 30 years.

Coal mining rights are amortized on a unit-of-production basis over the economically recoverable reserves evaluated based on the reserves estimated in accordance with the standards of the mine concerned.

(iv)Impairment

An impairment review is performed when there are indicators that the carrying amount of the mineral exploration rights and mining rights may exceed their recoverable amounts. To the extent that this occurs, the excess is fully provided as an impairment loss.

Leases

Leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group.

Contracts may contain both lease and non-lease components. We allocate the consideration in the contract to the lease and non-lease components based on their relative stand-alone prices. However, for leases of real estate for which we are a lessee, it has elected not to separate lease and non-lease components and instead accounts for these as a single lease component.

Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. The lease agreements do not impose any covenants other than the security interests in the leased assets that are held by the lessor. Leased assets may not be used as security for borrowing purposes.

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments:

● fixed payments (including in-substance fixed payments), less any lease incentives receivable;

90

● variable lease payments that are based on an index or a rate, initially measured using the index or rate as of the commencement date;

● amounts expected to be payable by us under residual value guarantees;

● the exercise price of a purchase option if we are reasonably certain to exercise that option, and

● payments of penalties for terminating the lease, if the lease term reflects us exercising that option.

Lease payments to be made under reasonably certain extension options are also included in the measurement of the liability.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, which is generally the case for leases in the Group, the lessee’s incremental borrowing rate is used, being the rate that the individual lessee would have to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment with similar terms, security and conditions.

To determine the incremental borrowing rate, we:

● where possible, use recent third-party financing received by the individual lessee as a starting point, adjusted to reflect changes in financing conditions since third party financing was received;

● use a build-up approach that starts with a risk-free interest rate adjusted for credit risk for leases held by the Group, which does not have recent third-party financing, and,

● make adjustments specific to the lease, such as term, country, currency and security.

If a readily observable amortizing loan rate is available to the individual lessee (through recent financing or market data) which has a similar payment profile to the lease, then our entities use that rate as a starting point to determine the incremental borrowing rate.

We are exposed to potential future increases in variable lease payments based on an index or rate, which are not included in the lease liability until they take effect. When adjustments to lease payments based on an index or rate take effect, the lease liability is reassessed and adjusted against the right-of-use asset.

Lease payments are allocated between principal and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

Right-of-use assets are measured at cost comprising the following:

● the amount of the initial measurement of lease liability;

● any lease payments made at or before the commencement date less any lease incentives received;

● any initial direct costs, and

● restoration costs.

Right-of-use assets are generally depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis as follows:

Buildings	2–20 years
Machinery	2–10 years
Land use rights	10–50 years

91

If we are reasonably certain to exercise a purchase option, the right-of-use asset is depreciated over the underlying asset’s useful life. While we revalue our land and buildings that are presented within property, plant and equipment, we have chosen not to do so for the right-of-use buildings held by us.

Payments associated with short-term leases of equipment and vehicles and all leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss. We apply the short-term lease recognition exemption to our short-term leases of machinery and equipment (that is those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). We also apply the recognition exemption for leases of low-value assets to leases of office equipment that are considered to be of low value (i.e. below RMB30,000).

Rental income is recognized on a time proportion basis over the lease terms. Variable lease payments that do not depend on an index or a rate are recognized as income in the accounting period in which they are incurred.

Impairment of financial assets

We recognize an allowance for expected credit losses (“ECLs”) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that we expect to receive, discounted at an approximation of the original effective interest rate. The impact of COVID-19 on GDP and other key indicators have been considered when determining the severity and likelihood of downside economic scenarios that are used to estimate ECL under IFRS 9 in 2021.

Impairment of non-financial assets

Goodwill and intangible assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment, or more frequently if events or changes in circumstances indicate that they might be impaired. Other assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows which are largely independent of the cash inflows from other assets or groups of assets (cash-generating units). Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at the end of each reporting period.

Inventories

Raw materials and stores, work in progress and finished goods are stated at the lower of cost and net realizable value. Cost comprises direct materials, direct labor and an appropriate proportion of variable and fixed overhead expenditure, the latter being allocated on the basis of normal operating capacity. Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs of purchased inventory are determined after deducting rebates and discounts. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

Current and deferred income tax

The income tax expense or credit for the period is the tax payable on the current period’s taxable income based on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences and to unused tax losses.

Current income tax

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period in the countries where we and our subsidiaries and associates operate and generate taxable income. Our management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. We measure our tax balances either based on the most likely amount or the expected value, depending on which method provides a better prediction of the resolution of the uncertainty.

92

Deferred income tax

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. Deferred income tax is also not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the end of the reporting period and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred tax assets are recognized only if it is probable that future taxable amounts will be available to utilize those temporary differences and losses.

Deferred tax liabilities and assets are not recognized for temporary differences between the carrying amount and tax bases of investments in foreign operations where we are able to control the timing of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities and where the deferred tax balances relate to the same taxation authority. Current tax assets and tax liabilities are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

Current and deferred tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

Revenue recognition

Revenue from contracts with customers

Revenue from contracts with customers is recognized when control of goods or services is transferred to the customers at an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services.

When the consideration in a contract includes a variable amount, the amount of consideration is estimated to which we will be entitled in exchange for transferring the goods or services to the customer. The variable consideration is estimated at contract inception and constrained until it is highly probable that a significant revenue reversal in the amount of cumulative revenue recognized will not occur when the associated uncertainty with the variable consideration is subsequently resolved.

When the contract contains a financing component which provides the customer with a significant benefit of financing the transfer of goods or services to the customer for more than one year, revenue is measured at the present value of the amount receivable, discounted using the discount rate that would be reflected in a separate financing transaction between us and the customer at contract inception. When the contract contains a financing component which provides us a significant financial benefit for more than one year, revenue recognized under the contract includes the interest expense accreted on the contract liability under the effective interest method. For a contract where the period between the payment by the customer and the transfer of the promised goods or services is one year or less, the transaction price is not adjusted for the effects of a significant financing component, using the practical expedient in IFRS 15.

(a)Sale of industrial products

Revenue from the sale of industrial products (including sales of scrap and other materials) is recognized at the point in time when control of the asset is transferred to the customer, generally on delivery of the industrial products. Revenue from electricity is recognized upon transmission of electricity based on the confirmation from the power grid.

93

(b)Rendering of services

We provide transportation and other service and the revenue from services is recognized over time, using an input method to measure progress towards complete satisfaction of the service, because the customer simultaneously receives and consumes the benefits provided by the Group.

For the period from May 22, 2020 to May 29, 2020, Chinalco increased its shareholding in the Company by 16,314,000 H shares on a cumulative basis through its subsidiary, representing approximately 0.10% of our total issued share capital as of December 31, 2020.

As an owner of at least 30% of our issued and outstanding shares, the parent company is deemed a controlling shareholder and therefore may not exercise its voting rights with respect to various matters related to our shares in a manner prejudicial to the interests of our other shareholders. See “Item 10. Additional Information - B. Memorandum and Articles of Association.” In accordance with our Articles of Association, each share of our capital stock has one vote and the shares of the same class have the same rights. Other than the foregoing restrictions, the voting rights of our major holders of domestic and H Shares are identical to those of any other holders of the same class of shares. Holders of domestic shares and H Shares are deemed to be shareholders of different classes for some matters, which may affect their respective interests. Other than the foregoing, holders of H Shares and domestic shares are entitled to the same voting rights.

(i) in the ordinary and usual course of our business;

(ii) with the terms of the transaction being fair and reasonable as far as our shareholders are concerned;

Under the Company Law of the PRC and our Articles of Association, all of our shareholders have equal rights to dividends and distributions. The holders of the H Shares share proportionately on a per share basis in all dividends and other distributions declared by our Board. Any final dividend for a fiscal year is subject to shareholders’ approval. Cash dividends, if made, are declared in Renminbi with respect to H Shares on a per share basis and paid in HK dollars. The Bank of New York Mellon, as depositary, converts the HK dollar dividend payments and distributes them to holders of ADSs in U.S. dollars, less expenses of conversion.

We believe that our dividend policy strikes a balance between two important goals of providing our shareholders with a competitive return on investment and assuring sufficient reinvestment of profits to enable us to achieve our strategic objectives. The declaration of dividends is subject to the discretion of our Board, which takes into account the following factors:

● our financial results;

● capital requirements;

● contractual restrictions on the payment of dividends by us to our shareholders or by our subsidiaries to us;

119

● our shareholders’ interests;

● the effect on our creditworthiness;

● general business conditions; and

● other factors our Board may deem relevant.

Under our current profit distribution policy as set forth in our Articles of Association, the basic principles of such policy include (i) giving adequate consideration to return to investors and making dividends to shareholders in an applicable percentage of the distributable profits, (ii) maintaining the continuity and stability of our dividend policy, while taking into consideration of our interests in the long term and the overall interests of all shareholders, as well as our sustainable development; and (iii) giving priority to dividends in cash.

More specifically, under such policy, we may make dividends in cash, in shares or in a combination of both cash and shares. Subject to conditions, we may make interim profit distributions. Save in exceptional circumstances, if our profit for the year and our cumulative undistributed profit are positive, we may make dividends in cash and (i) the profit to be distributed in cash per annum will not be less than 10% of the distributable profit realized for that year, or (ii) the total profit to be distributed in cash in the past three years will not be less than 30% of the average annual distributable profit realized in the past three years.

Pursuant to PRC laws and regulations, dividends may only be distributed after allowance has been made for: (1) recovery of losses, if any and (2) allocations to the statutory surplus reserve. The allocations to the statutory surplus reserve is 10% of our net profit determined in accordance with PRC Generally Accepted Accounting Principles, unless the accumulated statutory surplus reserve exceeds 50% of our registered share capital, in which case the surplus reserve is discretional.

See “Item 10. Additional Information - E. Taxation” for a discussion of the tax consequences of receipt of dividends.

B.Significant Changes

Item 10.Additional Information

A.Share Capital

Not applicable.

B.Memorandum and Articles of Association

The following is a summary of certain provisions of our Articles of Association, as amended. Such summary does not purport to be complete. For further information, you and your advisors should refer to the text of our Articles of Association, as amended, and to the texts of applicable laws and regulations. A copy of our Articles of Association is filed as an exhibit to this annual report.

Our objects and purposes

Our Articles of Association as amended from time to time are filed with the Hong Kong Companies Registrar. Our business purpose and business scope can be found in Article 13 and Article 14, respectively, of our Articles of Association.

120

Directors’ power to vote on matters in which he or she has an interest

Under Article 174, a director shall not vote in any resolution of the board of directors for approving any contract, transaction or arrangement in which such director or any of his associates (as defined in the applicable rules governing the listing of securities amended from time to time) is materially interested, and shall not be counted into the quorum of the meeting either. Unless the interested director has disclosed his or her interest to the board of directors in accordance with Article 174 and the contract, transaction or arrangement has been approved by the board of directors at a meeting in which the interested director is not counted in the quorum and has refrained from voting, a contract, transaction or arrangement in which such director is materially interested is voidable at the instance of our Company except as against a bona fide party thereto acting without notice of the breach of duty by such director. According to Article 86(2), matters concerning the remuneration of directors shall be decided by the shareholders’ general meeting.

Borrowing powers

Subject to compliance with applicable laws and regulations of the PRC, we have the power to raise and borrow money which power includes (without limitation) the issuance of debentures and the charging or mortgaging of part or whole of our business or properties and other rights permitted. The Articles of Association do not contain any specific provision in respect of the manner in which borrowing powers may be exercised by the directors nor do they contain any specific provision in respect of the manner in which such powers may be varied, other than (a) provisions which give the directors the power to formulate proposals for the issuance of debentures by us; (b) Article 87(2), which provides that the issuance of bonds must be approved by the shareholders in a general meeting by way of a special resolution; and (c) Article 112(4), which provides that the directors have the power to formulate our annual final financial budgets and final accounts.

Age limit for retirement

There is no provision pertaining to the retirement of directors pursuant to an age limit requirement in our Articles of Association.

Directors’ qualifying shares

Under Article 107, the directors are not required to hold any qualifying shares.

Dividend rights

Article 55(1) provides that holders of our ordinary shares have the right to receive dividends and distribution of profits in other forms, in proportion to the number of shares held. Under Article 49, when we convene a shareholders’ general meeting, distribute dividends, liquidate or perform other activities that require the verification of equity rights, the Board or the general meeting convener must specify a date as the record date. The shareholders registered in the shareholder register at closing on the record date are our shareholders entitled to appropriate rights and interests. Article 207 provides that under the premise of obeying the laws of the PRC, we have the right to forfeit the unclaimed dividends, subject to the expiry of the applicable relevant limitation period.

Voting rights

Article 55(2) provides that holders of our ordinary shares have the right to lawfully request, convene, chair, attend in person or appoint a proxy to attend and vote at shareholders’ meetings in respect of the number of shares held. Each ordinary share is entitled to one vote on all matters submitted to a vote of our shareholders at all shareholders’ meetings, except for (i) the cumulative voting system under Article 110; and (ii) meetings of a special class of shareholders where only holders of shares of the affected class are entitled to vote on the basis of one vote per share of the affected class, but Article 98 provides that interested shareholders shall not vote at class shareholders’ meetings. Article 110 provides that in the case that our controlling shareholders’ shareholding percentage is more than 30%, the cumulative voting system may be implemented for the election of directors and supervisors at a shareholders’ general meeting.

A special resolution of the shareholders’ general meeting will be required for important matters specified in Article 87, such as the increase or reduction of the registered capital and issuance of any class of shares, amendments to our Articles of Association, and our division, merger, dissolution and liquidation, and a special resolution must be adopted by shareholders in attendance (including proxies) at the meeting with supermajority votes as set forth in Article 80. For other matters to be approved in a shareholders’ general meeting, an ordinary resolution as set forth in Article 80 will need to be adopted.

121

Rights to share profits

Article 61(7) provides that a plan for profit distribution and a plan for making up for losses formulated by the Board in accordance with Article 112(6) must be approved by way of the shareholders’ general meeting.

Rights to share surplus in the event of liquidation

Article 55(6) provides that the holders of ordinary shares have the right to participate in the distribution of our surplus assets in proportion to the number of shares held in the event of the termination or liquidation of us. Article 228 sets forth the order of priority of payments out of our properties in the event of liquidation.

Enforceability of Shareholders’ Rights

Our Articles of Association provide that, with certain limited exceptions, where disputes and claims which concern our affairs and are based on rights or obligations provided for in our Articles of Association, the Company Law of the PRC or other relevant laws arise between holders of H Shares and us, holders of A Shares, or our director, supervisor, general manager or other senior management staff, such disputes and claims must be submitted to arbitration. Chapter 23 of our Articles of Association sets forth further details of the dispute resolution procedure.

Redemption provisions; sinking fund provisions and liability to further capital calls

Article 30 provides that we may repurchase issued shares in compliance with the requirements provided in relevant PRC laws and regulations, regulatory requirements or the Articles of Association and with the approvals from the relevant governing authorities of PRC under the following circumstances: (1) reduction of our registered capital; (2) merger with another company which owns our shares; (3) use of shares for our employee shareholding scheme or as equity incentive; (4) shareholders disagreeing with our general meeting’s resolution on merger or division and requiring us to acquire the shares in their possession; (5) use of shares for conversion of corporate bonds convertible into our shares; (6) where it is necessary to safeguard our value and the rights and interests of our shareholders; and (7) other circumstances required by law and administrative regulations. Under Articles 32 and 33, share repurchases by agreements outside a stock exchange are generally subject to our shareholders’ approval. Under Article 33, share repurchases under the circumstances described in items (1), (2) and (3) above shall be resolved at the shareholders’ general meeting, while share repurchases under the circumstances described in item (5) and (6) above shall be subject to approval by more than two-thirds of directors present at the meeting of the Board.

No shares issued by us are redeemable, entitled to a sinking fund or subject to liability for further capital calls.

Actions necessary to change the rights of holders of our shares or holders of a class of shares

Under Article 87(5), revision of any rights of class shareholders, e.g., rights to dividends, share profits or surplus in the event of liquidation or voting rights, requires a special resolution of the shareholders’ general meeting. A special resolution must be adopted by shareholders in attendance (including proxies) at the meeting with supermajority votes as set forth in Article 80.

The rights attached to any class of shares may be varied or abrogated only with the sanction of a special resolution passed at the shareholders’ general meeting and by holders of shares of the affected class passed at a separate general meeting of the class convened in accordance with Articles 97 to 101, respectively. The circumstances which are deemed to be a variation or abrogation of the class rights, including alternation of the number of shares of the class, are set forth under Article 97. Except for the circumstances under Article 97(1), (9) and (10), shareholders of the affected class, whether or not otherwise having the right to vote at shareholders’ general meetings, have the right to vote at class meetings but interested shareholders (which is defined under Article 98) are not entitled to vote at class meetings.

Resolutions of a class meeting shall be passed by the required percentage of shares (as specified under Article 99) with voting rights held by the class shareholders who, according to Article 98, are entitled to vote at that class meeting. Written notice must be given to all shareholders who are registered as holders of that class in the register of shareholders 45 days (inclusive of date of meeting) before the date of the class meeting. Such notice must contain the matters to be considered at such meeting, the date and the place of meeting. Those shareholders of the class who intend to attend shall send the written reply to us 20 days before the class meeting according to Article 100.

122

The proceedings of class meetings shall be conducted as near as possible to those of shareholders’ general meetings. The provisions in the Articles of Association relating to the proceedings of shareholders’ general meetings shall apply to class meetings.

The special procedures for approval by a class of shareholders do not apply where we issue, upon approval by special resolution of shareholders in a general meeting, either separately or concurrently once every 12 months, domestic shares and H Shares not more than 20% of the outstanding shares of the respective class.

Provisions discriminating against any existing or prospective shareholder as a result of owning a substantial number of shares

Chinalco, as our controlling shareholder (which is defined under Article 59), shall not exercise its voting rights in a manner prejudicial to the interest of all or some part of the shareholders when making decisions:

● to relieve a director or supervisor of his duty to act honestly in our best interest;

● to approve the expropriation by a director or supervisor (for his own benefit or for the benefit of another) of our assets, in any manner, including but not limited to an opportunity beneficial to us; or

● to approve the expropriation by a director or supervisor (for his own benefit or for the benefit of another) the individual rights of other shareholders, including but not limited to rights to distributions and voting rights save and except for our restructuring, submitted for approval by the shareholders in a general meeting in accordance with the Articles of Association.

Conditions governing the manner in which annual general meetings and extraordinary general meetings of shareholders are convoked

Shareholders’ general meetings can be held as annual general meetings or extraordinary general meetings. Annual general meetings are held once a year within six months after the end of the preceding fiscal year.

The Board is required to convene an extraordinary general meeting within two months of the occurrence of any of the following circumstances:

(1) the number of directors falls below the number required by the Company Law of the PRC or two-thirds of the number required by the Articles of Association;

(2) our unrecovered losses amount to one-third of the total amount of our paid-in-capital;

(3) upon the request of shareholder(s) holding 10% or more of our shares for more than ninety consecutive days (the number of shares held shall be the figures as of the date of the written request from the shareholder); and

(4) whenever the Board deems necessary or the supervisory committee proposes to convene the same.

We shall, within 45 days (inclusive of date of the meeting) before the date of the meeting, send written notices of the shareholders’ general meeting and inform all registered shareholders of the matters to be considered at the meeting and the date and venue of the meeting. Those shareholders who intend to attend the meeting shall send the written reply to us 20 days before the meeting. The meeting may be held if the number of voting shares represented by the shareholders intending to attend the meeting meets the threshold prescribed under Article 66. Otherwise, we shall, within five days, inform the shareholders once again of the matters to be considered at, and the date and place of, the meeting in the form of a public announcement, after which we may hold the meeting. A meeting and the resolutions adopted thereat shall not be invalidated due to the accidental omission to give notice of the meeting to, or the non-receipt of notice of the meeting by, a person entitled to receive notice. Motions put forward at the general meeting shall be specific and shall relate to the matters to be considered at a shareholders’ general meeting. Motions raised at a general meeting shall:

(1) be free of conflicts with the provision of laws, administrative regulations and Articles of Association, and fall within our business scope and the terms of the reference of the shareholders’ general meeting;

(2) have definite topics to discuss and specific matters to resolve; and

123

(3) be submitted in writing or served to the board of directors.

Limitations on the rights to own securities

Under Article 19, the shares issued to domestic investors and denominated in Renminbi are Domestic-Invested Shares whereas the shares issued to overseas investors and denominated in foreign currency are Foreign-Invested Shares.

Provisions having an effect of delaying, deferring or preventing a change in control

Under Article 116, decisions in respect of market development, merger and acquisition, and investment in a new field, where the consideration to be paid or the assets to be acquired exceed 10% of our total assets, the Board is required to engage relevant professional consultants to provide professional opinions, which shall serve as the key reference for the decision of the Board concerning such investment, merger or acquisition.

Under Article 87(3), division, merger, dissolution and liquidation of us and material acquisitions and disposals by us must be approved by a special resolution at a shareholders’ general meeting.

There are no provisions under the Articles of Association pertaining to the ownership threshold above which shareholder ownership must be disclosed.

Conditions governing changes in registered capital

Under Article 112(7), any proposal for the increase or decrease of our registered capital must be formulated by the Board. Article 87(1) further provides that any increase or reduction in share capital requires adoption of a special resolution at a shareholders’ general meeting. In addition, according to Article 97, alternation of the number of shares of a class or of a different class having voting rights, distribution rights or other privileges equal or superior to such class is regarded as alternation or abolishment of rights of such class, and must satisfy the requirements for shareholders’ meetings of the affected class. See “—Actions necessary to change the rights of holders of our shares or holders of a class of shares.”

Certain Differences Between PRC Company Law and Delaware Corporate Law

We are a PRC joint stock company, which is a corporate entity organized under the Company Law of the PRC. The PRC company law differs from laws applicable to United States corporations and their shareholders. A description of securities registered under Section 12 of the Exchange Act is filed as Exhibit 2.4 to this annual report on Form 20-F and includes a summary of certain significant differences between the provisions of the PRC company law applicable to us and the comparable provisions of the laws applicable to companies incorporated in the United States and their shareholders (for this purpose we refer to Delaware corporate law). Such summary does not purport to be complete and is subject to and qualified in its entirety by reference to our Articles of Association, as amended, and to the relevant laws and regulations.

C.Material Contracts

For the two years immediately preceding the date of this annual report, we have not entered into any additional material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company - A. History and Development of the Company” and “Item 7. Major Shareholders and Related Party Transactions - B. Related Party Transactions.”

D.Exchange Controls

The existing PRC foreign exchange regulations have significantly reduced government foreign exchange controls for transactions under the current account, including trade and service-related foreign exchange transactions and payment of dividends. We may undertake current account foreign exchange transactions without prior approval from the SAFE by producing commercial documents evidencing such transactions, provided that they are processed through Chinese banks licensed to engage in foreign exchange transactions. The PRC government has stated publicly that it intends to make the Renminbi freely convertible in the future. However, we cannot predict whether the PRC government will continue its existing foreign exchange policy and when the PRC government will allow free conversion of Renminbi to foreign currency.

124

Foreign exchange transactions under the capital account, including principal payments in respect of foreign currency-denominated obligations, continue to be subject to significant foreign exchange controls and require the approval of the SAFE. These limitations could affect our ability to obtain foreign exchange through debt or equity financing, or to obtain foreign exchange for capital expenditures.

Since 1994, the conversion of Renminbi into HK and U.S. dollars has been based on rates set by the PBOC, which are set daily based on the previous day’s PRC interbank foreign exchange market rate and current exchange rates on the world financial markets. From 1994 to July 20, 2005, the official exchange rate for the conversion of Renminbi to U.S. dollars was generally stable. On July 21, 2005, the PRC government introduced a managed floating exchange rate system to allow the value of the Renminbi to fluctuate within a regulated band based on market supply and demand and by reference to a basket of currencies. Since then, the PRC government has made, and may in the future make, further adjustments to the exchange rate system. In April 2012, the PRC government took a milestone step in turning the Renminbi into a global currency by doubling the size of its trading band against the U.S. dollar, pushing through a crucial reform that further liberalizes its financial markets. The PBOC allows the Renminbi to rise or fall 1% from a mid-point every day, effective April 16, 2012, compared with its previous 0.5% limit. The PBOC further allows the Renminbi to rise or fall 2% from a mid-point every day, effective March 17, 2014. In August 2015, the PBOC announced that the daily central parity quotes the market-makers reported to the China Foreign Exchange Trade System operated by the PBOC before the market opens should be based on the closing rate of the inter-bank foreign exchange rate market on the previous day, supply and demand in the market, and price movement of major currencies, effective on August 11, 2015. Fluctuations in exchange rates may adversely affect the value, translated or converted into U.S. dollars or HK dollars, of our net assets, earnings and any declared dividends. We cannot give any assurance that any future movements in the exchange rate of the Renminbi against the U.S. dollar and other foreign currencies will not adversely affect our results of operations and financial condition.

E.Taxation

PRC Taxation

The following summary of the material PRC and United States federal income tax provisions relating to the ownership and disposition of H Shares or ADSs held by the investor as capital assets is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change, and does not constitute legal or tax advice. This summary does not deal with all possible tax consequences relating to an investment in our ordinary shares, such as the tax consequences under state, local and other tax laws.

Dividends Paid to Individual Investors

Any shares registered in the name of our depositary bank will be deemed as being held by non-resident enterprise shareholders and the dividends attributable to the corresponding ADSs will be subject to the withholding of the PRC corporate income tax. We are therefore required to withhold 10% corporate income tax when we make dividend distributions to the investors of our ADSs. Investors of our ADSs will not be subject to further PRC individual income tax or PRC corporate income tax. The 10% dividend withholding tax rate is not subject to any reduction under the 1984 Agreement between the United States and the People’s Republic of China for the Avoidance of Double Taxation, or the PRC Treaty.

Capital Gains

With respect to foreign enterprises which are established under the laws of non-PRC jurisdictions and have no establishment or residence in China or whose capital gains from China do not relate to their establishment or residence in China (“non-resident foreign enterprises”), according to the Enterprise Income Tax Law and its implementation rules, which became effective on January 1, 2008, capital gains realized by non-resident foreign enterprises are ordinarily subject to capital gains tax at the rate of 10%, unless exempted or reduced pursuant to an applicable double-taxation treaty or other exemptions. The capital gains realized by resident enterprises, including enterprises established under the laws of non-PRC jurisdictions but whose “de facto management body” is located in the PRC, upon the sales of overseas-listed shares are subject to the PRC enterprise income tax.

With respect to foreign individual investors, the Provisions for Implementation of Individual Income Tax Law of China, as amended, stipulated that individual income tax on gains realized on the sale of equity shares shall be regulated in separate rules to be drafted by the State Council of China. However, as of the date of this annual report, there are no such rules enacted by the State Council yet. On March 30, 1998, the MOF and the SAT jointly issued the “Circular of Taxation Regarding the Continued Exemption of Individual Income Taxes Levied on Income Obtained from the Transfer of Shares,” which provided that income derived from the transfer of shares issued by listed companies shall not be taxed as income for the purposes of levying individual income taxes after July 1, 1997.

125

For PRC mainland investors, on October 31, 2014, the SAT issued “Circular on Tax Policies Relating to the Pilot Program of Shanghai-Hong Kong Stock Connect,” which provided that any capital gain from transferring stocks listed on the Hong Kong Stock Exchange by a PRC mainland investor would not be subject to tax during the period from November 17, 2014 to November 16, 2017. For mainland enterprises, such capital gains would be included in its income and subject to income tax. On November 1, 2017, the MOF, the SAT and the CSRC jointly issued “Circular on Extending Individual Income Tax Policies Relating to the Shanghai-Hong Kong Stock Connect,” which provided that income generated from price differences through investment in stocks listed on the Hong Kong Stock Exchange by PRC mainland individual investors via the Shanghai-Hong Kong Stock Connect would be exempt from individual income tax from November 17, 2017 to December 4, 2019. On December 4, 2019, the MOF, the SAT and the CSRC jointly issued the “Circular on Extending Individual Income Tax Policies Relating to the Shanghai-Hong Kong Stock Connect, Shenzhen-Hong Kong Stock Connect and Mainland-Hong Kong Mutual Recognition of Funds,” which further exempts the individual income tax on income generated from transfer through investment in stocks listed on the Hong Kong Stock Exchange by PRC mainland individual investors via the Shanghai-Hong Kong Stock Connect or Shenzhen-Hong Kong Stock Connect and investment in Mainland-Hong Kong mutually recognized Funds from December 5, 2019 to December 31, 2022.

Tax Treaties

China currently has such treaties with more than one hundred countries and regions, including the following countries:

● the United States;

● Australia;

● Canada;

● France;

● Germany;

● Japan;

● Malaysia;

● Singapore;

● the United Kingdom; and

● the Netherlands.

Under most treaties, the rate of withholding tax imposed by China’s taxation authorities remains 10%. The double taxation treaty between China and the United States provides that 10% withholding tax rate will be applied to the gross amount of dividends repatriated to an eligible U.S. holder. Under the treaty, an eligible U.S. holder is a person who, by reason of domicile, residence, place of head office, place of incorporation or any other criterion of similar nature is subject to taxation in the United States, as applicable under the treaty’s “treaty shopping provisions.”

Additional China Tax Considerations

Pursuant to the prevailing stamp duty regulations, a stamp duty is not imposed by China on the transfer of shares, such as the H Shares or ADSs, of Chinese publicly traded companies that take place outside of China.

United States Federal Income Taxation

Each potential investor is strongly urged to consult its own tax advisor to determine the particular U.S. federal, state, local, treaty and foreign tax consequences of acquiring, owning or disposing of the H Shares or ADSs.

126

The following summary describes the principal U.S. federal income tax consequences of purchasing, owning and disposing of the H Shares or ADSs. This summary only applies to U.S. holders, as defined below, who hold the H Shares or ADSs as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986 as amended (the “Code”). This discussion does not address all of the tax consequences relating to the purchase, ownership and disposition of the H Shares or ADSs, and does not take into account U.S. holders that may be subject to special rules, including:

● financial institutions;

● insurance companies;

● tax-exempt organizations;

● real estate investment trusts, regulated investment companies, grantor trusts;

● persons that have a functional currency other than the U.S. dollar;

● persons that will own H Shares or ADSs through partnerships or other pass-through entities;

● persons that actually or constructively own 10% or more of the combined voting power of our voting stock or of the total value of our stock;

● dealers or traders in securities or currencies;

● certain former citizens or long-term residents of the United States;

● persons that will hold the H Shares or ADSs as a position in a “straddle” or as part of a “hedging” or “conversion” or other risk reduction transaction for U.S. federal income tax purposes;

● persons who receive the H Shares or ADSs as compensation for services;

● “dual resident” corporations;

● persons that generally mark their securities to market for U.S. federal income tax purposes;

● persons who are residents of the People’s Republic of China or who are subject to Hong Kong profits tax; or

● persons who purchase or sell the H Shares or ADSs as part of a wash sale for U.S. federal tax purposes.

Moreover, this description does not address U.S. federal estate, gift or alternative minimum taxes, the U.S. federal unearned income Medicare contribution tax, or any foreign state or local tax consequences of the acquisition, ownership and disposition of the H Shares or ADSs. Each U.S. holder should consult its tax advisor with respect to the U.S. federal, state, local and foreign tax consequences of acquiring, owning and disposing of H Shares or ADSs.

This discussion is based on the Code, its legislative history, final, temporary and proposed U.S. Treasury regulations promulgated thereunder, published rulings and court decisions as in effect on the date hereof, as well as on the agreement between the United States and the People’s Republic of China for the avoidance of double taxation (the “Treaty”), all of which are subject to change, or change in interpretation, possibly with retroactive effect. In addition, this discussion is based in part upon the assumption that each obligation in the deposit agreement and any related agreements will be performed according to its terms.

You are a “U.S. holder” if you are a beneficial owner of H Shares or ADSs and, for U.S. federal income tax purposes, are:

● an individual citizen or resident of the United States;

● a corporation created or organized under the laws of the United States or any political subdivision thereof;

127

● an estate the income of which is subject to U.S. federal income tax without regard to its source; or

● a trust: (i) subject to the primary supervision of a U.S. court and one or more U.S. persons (within the meaning of the Code) have the authority to control all substantial decisions of the trust; or (ii) that has validly elected to be treated as a U.S. person under applicable U.S. Treasury Regulations.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal tax purposes) holds H Shares or ADSs, the tax treatment of the partnership and a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. If an investor is a partner in a partnership that holds H Shares or ADSs, such investor should consult its tax advisor.

In general, if you hold ADSs evidencing H Shares, you will be treated as the owner of the H Shares represented by the ADSs. Exchanges of H Shares for ADSs, and ADSs for H Shares, generally will not be subject to United States federal income tax.

The tax treatment of your H Shares or ADSs will depend in part on whether or not we are classified as a passive foreign investment company, or PFIC, for United States federal income tax purposes. Except as discussed below under “—Passive Foreign Investment Company Rules,” this discussion assumes that we are not classified as a PFIC for U.S. federal income tax purposes.

INVESTORS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE PARTICULAR TAX CONSIDERATIONS APPLICABLE TO THEM RELATING TO THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE H SHARES OR ADSs, INCLUDING THE APPLICABILITY OF U.S. FEDERAL, STATE AND LOCAL TAX LAWS OR NON-U.S. TAX LAWS, ANY CHANGES IN APPLICABLE TAX LAWS AND ANY PENDING OR PROPOSED LEGISLATION OR REGULATIONS.

Distributions on the H Shares or ADSs

The gross amount of any distribution (without reduction for any PRC tax withheld) we make on the H Shares or ADSs, other than certain pro-rata distributions of the H Shares, will be includible in income as dividend income when you, in the case of the H Shares, or the depositary, in the case of ADSs, receive the distribution, actually or constructively. Because we do not calculate earnings and profits in accordance with U.S. tax principles, all distributions by us to U.S. holders will generally be treated as dividends. Any dividend will not be eligible for the dividends-received deduction allowed to certain U.S. corporations in respect of dividends received from U.S. corporations.

If you are a noncorporate U.S. holder, dividends that constitute qualified dividend income will be taxable to you at the preferential rates applicable to long-term capital gains provided that you hold the H Shares or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Dividends that we pay with respect to the H Shares or ADSs will be qualified dividend income, provided that, in the year that you receive the dividend, we are eligible for the benefits of the Treaty. We believe that we are currently eligible for the benefits of the Treaty, and we therefore believe that dividends that we currently distribute on the H Shares or ADSs constitute qualified dividend income. However, there can be no assurance that we will be eligible for the benefits of the Treaty in future taxable years, and there can therefore be no assurance that dividends that we distribute on the H Shares or ADSs will continue to constitute qualified dividend income in such years.

Furthermore, even if we are not eligible for the benefits of the Treaty in a taxable year, dividends on the ADSs will nevertheless be treated as qualified dividend income if the ADSs are readily tradable on an established securities market in the United States. So long as our ADSs remain listed on the NYSE, we are therefore expect that dividends on the ADSs will be treated as qualified dividend income irrespective of whether we eligible for the benefits of the Treaty. However, if our ADSs were to be delisted from the NYSE (as discussed above in “Item 3. Key Information – D. Risk Factors – The audit reports included in this annual report are prepared by auditors who are not inspected fully by the Public Company Accounting Oversight Board and, as such, you are deprived of the benefits of such inspection. In addition, legislative and regulatory developments related to U.S.-listed China-based companies due to lack of PCAOB inspection and other developments may have a material adverse impact on our listing and trading in the United States and the trading prices of our ADSs.”), our ADSs would no longer be readily tradable on an established securities market in the United States. If our ADSs were delisted from the NYSE, dividends paid with respect to ADSs will continue to be qualified dividend income so long as we continue to be eligible for the benefits of the Treaty (as discussed above).

128

The amount of the dividend distribution that you must include in your income as a U.S. holder will be the U.S. dollar value of the HK dollar payments made, determined at the spot HK dollar/U.S. dollar rate on the date the dividend is distributed, regardless of whether the payment is in fact converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date the dividend is distributed to the date you or the depositary convert the payment into U.S. dollars will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income. Dividends paid by us generally will constitute income from sources outside the United States for U.S. foreign tax credit limitation purposes and will generally be categorized as “passive income” for U.S. foreign tax credit purposes. We may be required to withhold PRC income tax on dividends paid to U.S. holders on the H Shares or ADSs. Subject to various limitations, any PRC tax withheld from distributions in accordance with the Treaty will be deductible or creditable against your U.S. federal income tax liability.

You may not be able to claim a foreign tax credit (and instead may qualify to claim a deduction) for non-U.S. taxes imposed on dividends paid on the H Shares or ADSs if you (i) have held the H Shares or ADSs for less than a specified minimum period, or (ii) are obligated to make related payments with respect to positions in substantially similar or related property (for example, pursuant to a short sale). The rules relating to the U.S. foreign tax credit are complex and U.S. holders may be subject to various limitations on the amount of foreign tax credits that are available. In addition, in the case of a noncorporate U.S. holder, rules similar to the special rules that apply in determining the foreign tax credit limitation when the taxpayer has foreign source capital gains that are taxed in the U.S. at the lower capital gains rate apply in determining the noncorporate U.S. holder’s foreign tax credit limitation arising from dividends that are taxed at the capital gains rate.

Sale, Exchange or Other Disposition

Upon a sale, exchange or other disposition of the H Shares, you will generally recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the U.S. dollar value of the amount realized and your tax basis, determined in U.S. dollars, in such H Shares. Generally, gain or loss recognized upon the sale or other disposition of H Shares or ADSs will be capital gain or loss, will be long-term capital gain or loss if the U.S. holder’s holding period for such H Shares or ADSs exceeds one year, and will be income or loss from sources within the United States for foreign tax credit limitation purposes. Long-term capital gains of noncorporate U.S. holders are generally taxed at preferential rates. The deductibility of capital losses is subject to significant limitations.

With respect to the sale or exchange of H Shares, the amount realized upon a sale of H Shares generally will be the U.S. dollar value on the settlement date for the sale in the case of a cash basis U.S. holder (or an accrual basis U.S. Holder that so elects). If H Shares are traded on an “established securities market,” a cash basis taxpayer or, if it so elects, an accrual basis taxpayer, will determine the U.S. dollar value of the amount realized by translating the amount received at the spot rate of exchange on the settlement date of the sale. A U.S. holder will have a tax basis in the foreign currency received equal to the U.S. dollar amount realized. Any currency exchange gain or loss realized on a subsequent conversion of the foreign currency into U.S. dollars for a different amount generally will be treated as ordinary income or loss from sources within the United States. However, if such foreign currency is converted into U.S. dollars on the date received by the U.S. holder, a cash basis or electing accrual basis U.S. holder should not recognize any gain or loss on such conversion.

Any gain or loss that you recognize upon a sale of the H Shares or ADSs will generally be U.S. source gain or loss for foreign tax credit limitation purposes. Under the Treaty, however, if any PRC tax were to be imposed on any gain from the disposition of H Shares or ADSs, the gain could be treated as PRC source income. In addition, under recently finalized Treasury regulations, you will generally be precluded from claiming a foreign tax credit in respect of any such taxes unless you are eligible for and elect to apply the benefits of the Treaty. U.S. holders are urged to consult their tax advisors regarding the tax consequences if a foreign tax is imposed on a disposition of H Shares or ADSs, including the availability of the foreign tax credit under their particular circumstances. Any Hong Kong stamp duty paid will not be a creditable tax for United States federal income tax purposes, although the proceeds that you are treated as receiving upon a sale of the H Shares will be reduced by the amount of the stamp duty.

Passive Foreign Investment Company Rules

A non-U.S. corporation is a PFIC for any taxable year in which, after applying relevant look-through rules with respect to the income and assets of subsidiaries:

● 75% or more of its gross income consists of passive income, such as dividends, interest, rents, royalties, and gains from the sale of assets that give rise to such income; or

129

● 50% or more of the average quarterly value of its gross assets consists of assets that produce, or are held for the production of, passive income.

Passive income generally includes dividends, interest, gains from the sale or exchange of investment property, rents and royalties, and certain other specified categories of income. However, passive income does not include certain rents and royalties derived from the active conduct of a trade or business. If the stock of a non-U.S. corporation is publicly traded for the taxable year, the asset test is applied using the fair market value of the assets for purposes of measuring such corporation’s assets. If we own at least 25% (by value) of the stock of another corporation, we will be treated, for purposes of the PFIC tests, as owning our proportionate share of the other corporation’s assets and receiving our proportionate share of the other corporation’s income for purposes of the PFIC income and asset tests.

Based on the composition of our assets and income and the current expectations regarding the price of the H Shares and ADSs, we believe that we were not a PFIC for U.S. federal income tax purposes with respect to our 2021 taxable year and we do not intend or anticipate becoming a PFIC in the foreseeable future. However, the determination of PFIC status is a factual determination that must be made annually at the close of each taxable year and, therefore, there can be no certainty as to our status in this regard until the close of the current or any future taxable year. Changes in the nature of our income or assets or a decrease in the trading price of our shares may cause us to be considered a PFIC in the current or any subsequent year. If we were a PFIC in any year during a U.S. holder’s holding period for the H Shares or ADSs, we would ordinarily continue to be treated as a PFIC for each subsequent year during which the U.S. holder owned the H Shares or ADSs.

If we were a PFIC in any taxable year that you held the H Shares or ADSs, you generally would be subject to special rules with respect to “excess distributions” made by us on the H Shares or ADSs and with respect to gain from your disposition of the H Shares or ADSs. An “excess distribution” generally is defined as the excess of the distributions you receive with respect to the H Shares or ADSs in any taxable year, other than the taxable year in which your holding period in the H Shares or ADSs begins, over 125% of the average annual distributions you have received from us during the shorter of the three preceding years, or your holding period for the H Shares or ADSs that preceded the taxable year in which you receive the distribution. Generally, you would be required to allocate any excess distribution or gain from the disposition of the H Shares or ADSs ratably over your holding period for the H Shares or ADSs. The portion of the excess distribution or gain allocated to a prior taxable year, other than a year prior to the first year in which we became a PFIC, would be taxed at the highest U.S. federal income tax rate in effect for such taxable year, and you would be subject to an interest charge on the resulting tax liability, determined as if the tax liability had been due with respect to such particular taxable years. The portion of the excess distribution or gain that is not allocated to prior taxable years, together with the portion allocated to the years prior to the first year in which we became a PFIC, would be included in your gross income for the taxable year of the excess distribution or disposition and taxed as ordinary income.

These adverse tax consequences may be mitigated if the U.S. holder is eligible to and does elect to annually mark-to-market the H Shares or ADSs. If a U.S. holder makes a mark-to-market election, such holder will generally include as ordinary income the excess, if any, of the fair market value of the H Shares or ADSs at the end of each taxable year over its adjusted basis, and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis of the H Shares or ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included in income as a result of the mark-to-market election). Any gain recognized on the sale or other disposition of the H Shares or ADSs will be treated as ordinary income and any loss would be an ordinary loss to the extent of the net amount of previously included income as a result of the market-to-market election and, thereafter, a capital loss. The mark-to-market election is available only for “marketable stock,” which is stock that is traded in other than de minimis quantities on at least 15 days during each calendar quarter on a qualified exchange or other market, as defined in the applicable Treasury regulations. The H Shares or ADSs may qualify as “marketable stock” because the ADSs are listed on the New York Stock Exchange.

A U.S. holder’s adjusted tax basis in the H Shares or ADSs will be increased by the amount of any income inclusion and decreased by the amount of any deductions under the mark-to-market rules. If a U.S. holder makes a mark-to-market election it will be effective for the taxable year for which the election is made and all subsequent taxable years unless the H Shares or ADSs are no longer regularly traded on a qualified exchange or the IRS consents to the revocation of the election. U.S. holders are urged to consult their tax advisors about the availability of the mark-to-market election, and whether making the election would be advisable in their particular circumstances. However, the stock of any of our subsidiaries that were PFICs would not be eligible for the mark-to-market election.

Alternatively, a timely election to treat us as a qualified electing fund could be made to avoid the foregoing rules with respect to excess distributions and dispositions. You should be aware, however, that if we become a PFIC, we do not intend to satisfy the recordkeeping requirements that would permit you to make a qualified electing fund election.

130

In addition, notwithstanding any election you make with regard to the shares or ADSs, dividends that you receive from us will not constitute qualified dividend income to you if we are a PFIC (or are treated as a PFIC with respect to you) either in the taxable year of the distribution or the preceding taxable year. Dividends that you receive that do not constitute qualified dividend income are not eligible for taxation at the preferential rates applicable to qualified dividend income. Instead, you must include the gross amount of any such dividend paid by us in your gross income, and it will be subject to tax at rates applicable to ordinary income.

If we were regarded as a PFIC, a U.S. holder of H Shares or ADSs may be required to file an information return on IRS Form 8621.

U.S. holders should consult their tax advisors concerning the U.S. federal income tax consequences of holding the H Shares or ADSs if we were considered to be a PFIC.

Information with Respect to Foreign Financial Assets

Owners of “specified foreign financial assets” with an aggregate value in excess of $50,000 (and in some circumstances, a higher threshold) may be required to file an information report with respect to such assets with their tax returns. “Specified foreign financial assets” may include financial accounts maintained by foreign financial institutions, as well as the following, but only if they are held for investment and not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-United States persons, (ii) financial instruments and contracts that have non-United States issuers or counterparties, and (iii) interests in foreign entities. Holders are urged to consult their tax advisors regarding the application of this reporting requirement to their ownership of the H Shares or ADSs.

Backup Withholding and Information Reporting

If you are a noncorporate U.S. holder, information reporting requirements, on IRS Form 1099, generally will apply to dividend payments or other taxable distributions made to you within the United States, and the payment of proceeds to you from the sale of the H Shares or ADSs effected at a United States office of a broker.

Additionally, backup withholding may apply to such payments if you fail to comply with applicable certification requirements or (in the case of dividend payments) are notified by the IRS that you have failed to report all interest and dividends required to be shown on your federal income tax returns.

Payment of the proceeds from the sale of the H Shares or ADSs effected at a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, a sale effected at a foreign office of a broker could be subject to information reporting in the same manner as a sale within the United States (and in certain cases may be subject to backup withholding as well) if (i) the broker has certain connections to the United States, (ii) the proceeds or confirmation are sent to the United States or (iii) the sale has certain other specified connections with the United States.

You generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed your income tax liability by filing a refund claim with the IRS.

Hong Kong Taxation

The following discussion summarizes the material Hong Kong tax provisions relating to the ownership of H Shares or ADSs held by you.

Dividends

Under current Hong Kong Inland Revenue Department practice, no Hong Kong tax is payable by the recipient in respect of dividends paid by us, either by withholding or otherwise, unless such dividends are attributable to a trade, profession or business carried on in Hong Kong.

131

Taxation of Capital Gains

Hong Kong profits tax is currently charged at a flat rate of 16.5% for corporations and 15% for unincorporated businesses and individuals, except that the respective half-rates of 8.25% and 7.5% apply for the first HK$2 million of assessable profits for years of assessment beginning on or after April 1, 2018.

No Hong Kong tax is imposed on capital gains arising from the sale of property (such as H Shares) acquired and held as a capital investment. However, if a person carries on a business in Hong Kong that includes trading and dealing in securities, and derives trading gains from such activities or from other Hong Kong sources, Hong Kong profits tax will be payable. Gains from sales of H Shares effected on the Hong Kong Stock Exchange are considered to be from a Hong Kong source for this purpose. The source of gains from off-exchange transactions is less clear and, generally, will depend on whether the purchase and sale contracts were negotiated and, in substance, concluded in Hong Kong. In addition, exemption from profits tax is available for certain classes of taxpayers, notably privately offered onshore and offshore funds operating in Hong Kong, as well as non-Hong Kong residents who do not otherwise carry on business in Hong Kong, subject to compliance with various other requirements.

The Hong Kong tax position with respect to gains from the disposal of ADSs is similar. However, no Hong Kong tax will apply on trading gains arising from the sale of ADSs where the purchase and sale were effected on the NYSE.

Hong Kong Stamp Duty

Hong Kong stamp duty is payable by each seller and purchaser for every sold note and every bought note created for every sale and purchase of “Hong Kong stock” (which means stock the transfer of which is required to be registered in Hong Kong), including the H Shares. Stamp duty is currently charged at the total rate of 0.26% of the value of the H Shares transferred (the buyer and seller each paying half of such stamp duty). In addition, a fixed duty of HK$5 is currently payable on an instrument of transfer of H Shares. If one of the parties to a sale is a non-resident of Hong Kong and does not pay the required stamp duty, the unpaid stamp duty will be assessed on the instrument of transfer (if any), and the transferee will be liable for the full payment of such amount.

If the withdrawal of H Shares when ADSs are surrendered or the issuance of ADSs when H Shares are deposited results in a change of beneficial ownership in the H Shares under Hong Kong law, Hong Kong stamp duty at the rate described above for sale and purchase transactions will apply. The issuance of ADSs for deposited H Shares issued directly to the depositary or for the account of the depositary should not lead to a Hong Kong stamp duty liability. Holders of the ADSs are not liable for the Hong Kong stamp duty on transfers of ADSs outside of Hong Kong so long as the transfers do not result in a change of beneficial interest in the H Shares under Hong Kong law.

Estate Duty

The Revenue (Abolition of Estate Duty) Ordinance 2005 came into effect on February 11, 2006 in Hong Kong. No Hong Kong estate duty is payable and no estate duty clearance papers are needed for an application for a grant of representation in respect of holders of H Shares or ADSs whose death occurs on or after February 11, 2006.

H.Documents on Display

We are subject to the periodic reporting and other informational requirements of the Exchange Act. Under the Exchange Act, we are required to file reports and other information with the SEC. Specifically, we are required to file an annual report under Form 20-F no later than four months after the close of each of our fiscal years, which is December 31, for fiscal years ended after December 15, 2011. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the SEC’s public reference room located at 100 F Street, NE, Washington, D.C. 20549. The public may obtain information regarding the Washington, D.C. Public Reference Room by calling the SEC at 1-800-SEC-0330. The SEC also maintains a website at www.sec.gov that contains reports and other information regarding registrants that make electronic filings with the SEC using its EDGAR filing system. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and officers, directors and principal shareholders of ours are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act.

I.Subsidiary Information

Not applicable.

Item 11.Quantitative and Qualitative Disclosures about Market Risk

We are exposed to various types of market risks, including credit risk relating to financial assets and changes in foreign exchange rates, interest rates and the prices of alumina and primary aluminum, in the normal course of business.

We borrow short-term, medium-term and long-term funds, including variable rate debts, principally denominated in Renminbi. We hedge a limited amount of our sales through the trade of futures contracts on the SHFE and LME. Our hedging activities are subject to policies approved by our senior management. Substantially all of the financial instruments we hold are for purposes other than trading.

The following discussion, which contains “forward-looking statements” that involve risks and uncertainties, summarize our market-sensitive financial instruments. Such discussions address markets risk only and do not present other risks, which we face in the normal course of business.

Credit Risk

Credit risk arises from balances with banks and financial institutions, trade and notes receivables, other current and non-current receivables as well as credit exposures of customers, including outstanding receivables and committed transactions. We also provide financial guarantees to certain subsidiaries. The carrying amounts of these receivables and amounts of financial guarantees represent our maximum exposure to credit risk in relation to our financial assets and guarantees.

We maintain substantially all of our bank balances and cash and short-term investments in several major state-owned banks in the PRC. Our directors are of the opinion that these assets are not exposed to significant credit risk.

With regard to receivables, the marketing department assesses the credit quality of the customers and related parties, taking into account their financial positions, past experience and other factors. We perform periodic credit evaluations of our customers and believe that adequate provisions for impairment of receivables have been made in the financial statements. Management does not expect any further losses from non-performance by these counterparties.

For the year ended December 31, 2021, revenues of approximately RMB53,205 million are derived from entities directly or indirectly owned or controlled by the PRC government including Chinalco. There were no other individual customers from whom we have derived revenue of more than 10% of our revenue during the year ended December 31, 2019, 2020 and 2021. Thus, our directors are of the opinion that we were not exposed to any significant concentration of credit risk as of December 31, 2019, 2020 and 2021.

133

Foreign Exchange Rate Risk

We conduct our business primarily in Renminbi, which is our functional and reporting currency. We convert a portion of our Renminbi revenues into other currencies to meet foreign currency obligations and to pay for imported equipment and materials.

Many foreign currency exchange transactions involving Renminbi, including foreign exchange transactions under our capital account, are subject to foreign exchange controls and require the approval of the SAFE. Actions taken by the PRC government could cause future exchange rates to vary significantly from current or historical exchange rates. On July 21, 2005, the PBOC announced a reform of its exchange rate system. Under the reform, the Renminbi is no longer effectively linked to the U.S. dollar but instead is allowed to fluctuate within a narrow and managed band against a basket of foreign currencies, according to market demand and supply conditions. In April 2012, the PRC government took a milestone step in turning the Renminbi into a global currency by doubling the size of its trading band against the U.S. dollar, pushing through a crucial reform that further liberalizes its financial markets. The PBOC allows the Renminbi to rise or fall 1% from a mid-point every day, effective on April 16, 2012, compared with its previous 0.5% limit. The PBOC allows the Renminbi to rise or fall 2% from a mid-point every day, effective on March 17, 2014, compared with its previous 1% limit. In August 2015, the PBOC announced that the daily central parity quotes the market-makers reported to the China Foreign Exchange Trade System operated by the PBOC before the market opens should be based on the closing rate of the inter-bank foreign exchange rate market on the previous day, supply and demand in the market, and price movement of major currencies, effective on August 11, 2015. Any appreciation of the Renminbi will increase the prices of our export sales denominated in foreign currencies and reduce the Renminbi equivalent value of our trade and notes receivable denominated in foreign currencies, which may adversely affect our financial condition and results of operations. Our financial condition and operating performance may also be affected by changes in the value of currencies other than Renminbi in which our earnings and obligations are denominated.

Our bank balances and cash on hand as of December 31, 2021 amounted to RMB19,178.0 million, including Renminbi balances and foreign currency deposits of U.S. dollar, HK dollar, Euro and others, which translated into RMB1,557.4 million, RMB7.3 million, RMB2.0 million and RMB6.2 million, respectively. Most of our sales are domestic and as such we have a limited amount of foreign currency denominated receivables and payables. As of December 31, 2021, we had foreign currency denominated loans with principal amount of RMB11 million in Japanese Yen and RMB1,333 million in U.S. dollars. In addition, as of December 31, 2021, our trade and notes receivables, other current assets and trade and notes payables denominated in U.S. dollars amounted to RMB512 million, RMB99 million and RMB241 million, respectively; our other payables and accrued liabilities denominated in U.S. dollars and HK dollars amounted to RMB1.24 million and RMB0.16 million, respectively.

As of December 31, 2021, if the Renminbi had strengthened/weakened by 5% against U.S. dollars with all other variables held constant, the total comprehensive income for the year would have been approximately RMB28 million higher/lower, mainly as a result of foreign exchange gains and losses arising from the translation of U.S.-dollar-denominated borrowings, other payables and medium-term notes. Profit was less sensitive to the fluctuation in the RMB/U.S. dollars exchange rates in 2021 than in 2020, mainly due to a decrease in the US$ denominated other payables and long-term and short-term borrowings.

As the assets and liabilities denominated in other foreign currencies other than U.S. dollars were relatively minimal to our total assets and liabilities, our directors are of the opinion that we were not exposed to significant foreign currency risk arising from other assets and liabilities denominated in currency other than the functional currency of the group entities as of December 31, 2020 and 2021.

Interest Rate Risk

As of December 31, 2021, as we had no significant interest-bearing assets except for bank deposits and entrusted loans, our income and operating cash flows are substantially independent of changes in market interest rates.

Most of the bank deposits are maintained in savings and time deposit accounts in the PRC. The interest rates are regulated by the PBOC and our Group treasury closely monitors the fluctuation on such rates periodically. The interest rates of entrusted loans are fixed. As the interest rates applied to the entrusted loans were fixed, our directors are of the opinion that we were not exposed to any significant interest rate risk for our financial assets held as of December 31, 2020 and 2021.

The interest rate risk for our financial liabilities primarily arises from interest-bearing loans. Loans borrowed at floating interest rates expose us to cash flow interest rate risk. We enter into debt obligations to support general corporate purposes including capital expenditures and working capital needs. Our Group treasury closely monitors market interest rates and maintains a balance between variable rate and fixed rate borrowings in order to reduce the exposures to the interest rate risk described above.

134

As of December 31, 2021, if interest rates had been 100 basis points higher/lower for bank and other loans borrowed at floating interest rates with all other variables held constant, net profit for the year would have been RMB421 million lower/higher, respectively, mainly as a result of the higher/lower interest expense on floating rate borrowings.

Our interest rate risk for our financial liabilities also arises from medium-term notes and short-term bonds issued at fixed rates. As the fluctuation of comparable interest rates of corporate bonds with similar terms was relatively low, our directors are of the opinion that we are not exposed to any significant fair value interest rate risk for its fixed interest rate borrowings held as of December 31, 2020 and 2021.

Commodity Price Risk

We are exposed to fluctuations in the prices of alumina, primary aluminum and other products. We import a small portion of our alumina supply from suppliers outside China. Such purchases are made at market prices. In addition, all our sales of alumina, primary aluminum and other products are made at market prices. Therefore, fluctuations in the prices of alumina and primary aluminum have a significant effect on our operating performances.

We use mainly futures contracts and option contracts traded on the SHFE and the LME to hedge against fluctuations in primary aluminum prices. We use the futures contract for hedging other than speculation. As of December 31, 2021, the fair values of the outstanding futures and option contracts amounting to nil and RMB69 million were recognized in financial assets and financial liabilities at fair value through profit or loss, respectively.

As of December 31, 2020 and 2021, if the commodity futures prices had increased/decreased by 3% and all other variables held constant, the profit for the respective year would have changed by the amounts shown below:

	2020	2021
Primary aluminum	Decrease/increase RMB5 million	Decrease/increase RMB6 million

Liquidity risk

We monitor rolling forecasts of our liquidity requirements to ensure we have sufficient cash to meet operational needs while maintaining sufficient headroom on our undrawn committed borrowing facilities at all times so that we do not breach borrowing limits or covenants (where applicable) on any of our borrowing facilities. Such forecasts take into consideration our debt financing plans, covenant compliance, compliance with internal balance sheet ratio targets and, if applicable, external regulatory or legal requirements. Our management also monitors rolling forecasts of our liquidity reserve on the basis of expected cash flows.

As of December 31, 2021, we had total banking facilities of approximately RMB128,100 million, of which RMB36,056 million had been utilized, and unutilized banking facilities amounted to RMB92,044 million as of December 31, 2021, among which, banking facilities of approximately RMB25,530 million will remain unexpired over the 12 months from December 31, 2021. Our directors are confident that such banking facilities could be renewed upon their expiration based on our past experience with banks and our good credit standing. In addition, as of December 31, 2021, we had no credit facilities through our futures agent at LME. The futures agent has the right to adjust the related credit facilities.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d- 15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Our internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of a company’s assets, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors, and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the consolidated financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision of and with the participation of the principal executive officer and principal financial officer, our management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2021, based on the framework in the Internal Control-Integrated Framework (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission in May 2013.

Based on our evaluation under the framework in Internal Control-Integrated Framework (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission, our management concluded that, as of December 31, 2021, our internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with the IFRS.

Report of Independent Registered Public Accounting Firm

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Aluminum Corporation of China Limited and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of profit or loss and other comprehensive income, changes in equity and cash flows for the years then ended, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Impairment assessment of property, plant and equipment

As described in Note 3(a), and Note 7 to the consolidated financial statements, the Group’s net carrying value of property, plant and equipment (“PP&E) was RMB 93,427 million as of December 31, 2021. Management assesses related assets for potential impairment whenever there are indications that the carrying value of an asset or a group of assets may not be recoverable. As of December 31, 2021, management performed impairment assessment on PP&E with impairment indications at the level of cash generating unit (“CGU”) to which the PP&E was allocated using discounted cash flow model. The discounted cash flows model applied for the impairment assessment involved significant assumptions including product prices and discount rate. Based on the impairment test, RMB 2,328 million of impairment losses were recognized by management for PP&E for the year ended December 31, 2021.

The principal considerations for our determination that performing procedures relating to the impairment assessment of PP&E is a critical audit matter are there were significant judgements made by management in determining their respective recoverable amounts using discounted cash flows model. This in turn led to a high degree of auditor judgment, subjectivity and audit effort in evaluating management’s significant assumptions including product prices and discount rate. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included evaluating and testing the effectiveness of controls relating to management’s impairment assessment of PP&E, including controls over the development of model and significant assumptions used in the impairment assessment. These procedures also included, among others, (i) testing management’s process for determining the recoverable amount of PP&E with impairment indications; (ii) evaluating the appropriateness of the management’s model used to determine the recoverable amount; (iii) evaluating the reasonableness of significant assumption of the product prices by comparing the management forecast prices against historical prices and present market prices, taking into account the published forecast prices; (iv) testing the completeness, accuracy and relevancy of the underlying data used and the mathematical accuracy of the calculations in the model. Professionals with specialized skill and knowledge were used to assist in the evaluation of the appropriateness of the model and the reasonableness of certain significant assumptions, including the discount rate.

Impairment assessment of goodwill

As described in Note 3(b) and Note 6 to the consolidated financial statements, the Group’s carrying value of goodwill was RMB 3,510 million as of December 31, 2021. Management performed impairment assessment of goodwill on an annual basis. When performing the impairment assessment, the recoverable amount of the CGU to which the goodwill was allocated was estimated by management using discounted cash flows model, and compared with the carrying value of the CGU to determine if goodwill was impaired. The discounted cash flows model used for the impairment assessment involved significant assumptions including product prices, long-term growth rate and discount rate. No impairment losses were recognized by management for goodwill for the year ended December 31, 2021.

F-4

The principal considerations for our determination that performing procedures relating to the impairment assessment of goodwill is a critical audit matter are there were significant judgements made by management in determining their respective recoverable amounts using discounted cash flows model. This in turn led to a high degree of auditor judgment, subjectivity and audit effort in evaluating management’s significant assumptions including product prices, long-term growth rate and discount rate. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included evaluating and testing the effectiveness of controls relating to management’s impairment assessment of goodwill, including controls over the development of model and significant assumptions used in the impairment assessment. These procedures also included, among others, (i) testing management’s process for determining recoverable amount of goodwill; (ii) evaluating the appropriateness of management’s model used to determine recoverable amount; (iii) evaluating the reasonableness of significant assumption of the product prices used by management by comparing the management forecast price against historical prices and present market prices, taking into account the published forecast prices; and (iv) testing the completeness, accuracy and relevancy of the underlying data used and the mathematical accuracy of the calculations in the model. Professionals with specialized skill and knowledge were used to assist in the evaluation of the appropriateness of the model and the reasonableness of certain significant assumptions, including the long-term growth rate and discount rate.

NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

For the years ended December 31, 2019 ,2020 and 2021

(Amounts expressed in thousands of RMB unless otherwise stated)

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

This note provides a list of the significant accounting policies adopted in the preparation of these consolidated financial statements. These policies have been consistently applied to all the years presented, unless otherwise stated. The financial statements are for the Group consisting of the Company and its subsidiaries.

2.1     Basis of preparation

2.1.1  Compliance with IFRS

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

The preparation of the financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 3.

2.1.2  Going Concern

As of December 31, 2021, the Group’s current liabilities exceeded its current assets by approximately RMB3,467 million (December 31, 2020 (restated): RMB16,364 million). The directors of the Company have considered the Group’s available sources of funds as follows:

● The Group’s expected net cash inflows from operating activities in 2022;

● Unutilized banking facilities of approximately RMB92,044 million as of December 31, 2021, of which amounts totaling RMB25,530 million will remain unexpired over 12 months from December 31, 2021. The directors of the Company are confident that these banking facilities could be renewed upon expiration based on the Group’s past experience and good credit standing;

● Other available sources of financing from banks and other financial institutions given the Group’s credit history.

The directors of the Company believe that the Group has adequate resources to continue operations for the foreseeable future of not less than 12 months from December 31, 2021. The directors of the Company therefore are of the opinion that it is appropriate to adopt the going concern basis in preparing the consolidated financial statements.

2.1.3  Historical cost convention

The financial statements have been prepared on a historical cost basis except for certain financial assets and financial liabilities measured at fair value.

2.1.4  New and amended standards adopted by the Group

New standards and amendments that are effective for the first time for periods commencing on or after January 1, 2021 did not have any material impact on the amounts recognized in prior periods and are not expected to significantly affect the current or future periods.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.1     Basis of preparation (Continued)

2.1.5  New standards and interpretations not yet adopted

Certain new accounting standards and interpretations have been published that are not mandatorily effective for December 31, 2021 reporting period and have not been early adopted by the Group. These standards are not expected to have a material impact on the entity in the current or future reporting periods and on foreseeable future transactions.

2.1.6  Changes in accounting policies

(i) Presentation of transportation and logistic costs

The Group previously presented the transportation and logistic costs incurred to fulfill the sales contracts in “selling and distribution expenses” in the consolidated statement of profit or loss. In 2021, due to the mandatory change in the presentation of such transportation and logistic costs in the consolidated statement of profit or loss of the Group under Accounting Standard for Business Enterprise issued by the Ministry of Finance of China (“CAS”), i.e., change from “selling and distribution expenses” to “cost of sales”, the Group made the same change in presentation in the consolidated statement of profit or loss under IFRS. Accordingly, the comparative consolidated statement of profit or loss for the year ended December 31, 2019 and 2020 were restated with the amount of RMB1,229 million and RMB1,141 million reclassified from selling and distribution expenses to cost of sales, respectively. This change in accounting policy did not have any impact on the opening balance sheet of the Group for the years ended December 31, 2020 and 2021.

(ii) Accounting for the investments in associates and joint ventures in the separate financial statements

In the prior years, the Company accounted for the investments in associates and joint ventures at cost. In 2021, to make the carrying amounts of these investments better reflect their status and values, and to reduce the difference between the financial statements of the Company under IFRS and CAS, the Company changed the accounting for the investment in associates and joint ventures in the separate financial statements from cost method to equity method. This change in accounting treatment has been accounted for retrospectively and comparative information has been restated.

2.2     Principles of consolidation and equity accounting

2.2.1  Subsidiaries

Subsidiaries are all entities (including structured entities) over which the Group has control. The Group controls an entity where the Group is exposed to, or has rights to, variable returns from its involvement with the entity and affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.2     Principles of consolidation and equity accounting (Continued)

2.2.1  Subsidiaries (Continued)

The acquisition method of accounting is used to account for business combinations by the Group (Note 2.3).

Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated statement of profit or loss and other comprehensive income, statement of changes in equity and balance sheet respectively.

2.2.2  Associates

Associates are all entities over which the Group has significant influence but not control or joint control. This is generally the case where the Group holds between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting (Note 2.2.4), after initially being recognized at cost.

2.2.3  Joint arrangements

Under IFRS 11 ‘Joint Arrangements’, investments in joint arrangements are classified as either joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. The Group only has joint ventures.

Joint ventures

Interests in joint ventures are accounted for using the equity method (Note 2.2.4), after initially being recognized at cost in the consolidated statement of financial position.

2.2.4  Equity method

Under the equity method of accounting, the investments are initially recognized at cost and adjusted thereafter to recognize the Group’s share of the post-acquisition profits or losses of the investee in profit or loss, and the Group’s share of movements in other comprehensive income of the investee in other comprehensive income. Dividends received or receivable from associates and joint ventures are recognized as a reduction in the carrying amount of the investment.

Where the Group’s share of losses in an equity-accounted investment equals or exceeds its interest in the entity, including any other unsecured long-term receivables, the Group does not recognize further losses, unless it has incurred obligations or made payments on behalf of the other entity.

(Amounts expressed in thousands of RMB unless otherwise stated)

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.2     Principles of consolidation and equity accounting (Continued)

2.2.4  Equity method (Continued)

Unrealized gains on transactions between the Group and its associates and joint ventures are eliminated to the extent of the Group’s interest in these entities. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of equity-accounted investees have been changed where necessary to ensure consistency with the policies adopted by the Group.

The carrying amount of equity-accounted investments is tested for impairment in accordance with the policy described in Note 2.11.

2.2.5  Changes in ownership interests

The Group treats transactions with non-controlling interests that do not result in a loss of control as transactions with equity owners of the Group. A change in ownership interest results in an adjustment between the carrying amounts of the controlling and non-controlling interests to reflect their relative interests in the subsidiary. Any difference between the amount of the adjustment to non-controlling interests and any consideration paid or received is recognized in a separate reserve within equity attributable to owners of the Company.

When the Group ceases to consolidate or equity account for an investment because of a loss of control, joint control or significant influence, any retained interest in the entity is remeasured to its fair value with the change in carrying amount recognized in profit or loss. This fair value becomes the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss or transferred to another category of equity as specified/ permitted by applicable IFRSs.

If the ownership interest in a joint venture or an associate is reduced but joint control or significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income are reclassified to profit or loss where appropriate.

2.3     Business combination

(a)      Merger accounting for business combinations under common control

The consolidated financial statements incorporate the financial statements of the combining entities or businesses in business combination under common control as if they had been combined from the date when the combining entities or businesses first came under the control of the ultimate holding company.

The net assets of the combining entities or businesses are consolidated using the carrying amount from the ultimate holding company’s perspective. No amount is recognized for goodwill or excess of the Group‘s interest in the book value of the net assets over cost at the time of the common control combination, to the extent of the continuation of the ultimate holding company’s interest.

2.3     Business combination (Continued)

(a)      Merger accounting for business combinations under common control (Continued)

The consolidated statement of comprehensive income includes the results of each of the combining entities or businesses from the earliest date presented or since the date when the combining entities or businesses first came under common control, where this is a shorter period, regardless of the date of the common control combination.

The comparative financial data have been restated to reflect the business combinations under common control occurred during this year (Note 39).

Transaction costs, including professional fees, registration fees, costs of furnishing information to shareholders, costs or losses incurred in combining operations of the previously separate businesses and other costs incurred in relation to the common control combination that is to be accounted for by using the merger accounting method are recognized as expenses in the period in which they are incurred.

(b)      Acquisition method of accounting for other business combinations and goodwill

The acquisition method of accounting is used to account for the acquisition of subsidiaries by the Group, other than common control combinations. The consideration transferred is measured at the acquisition date fair value which is the sum of acquisition date fair value of assets transferred by the Group, liabilities assumed by the Group to the former owner of the acquiree and the equity interests issued by the Group in exchange for control of the acquiree. The consideration transferred included the fair value of any assets and liabilities resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at fair value at the acquisition date. All other components of non-controlling interests are measured at fair value. For each business combination, the Group elects whether to measure the non-controlling interests in the acquiree that are present ownership interests and entitle their holders to a proportional share of net assets in the event of liquidation at fair value or at the proportional share of the acquiree’s identifiable net assets.

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as of the acquisition date. This includes the separation of embedded derivatives in host contracts of the acquiree.

If the business combination is achieved in stages, the previously held equity interest is remeasured at its acquisition date fair value and any resulting gain or loss is recognized in profit or loss.

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred, the amount recognized for non-controlling interests and any fair value of the Group’s previously held equity interests in the acquiree over the identifiable net assets acquired and liabilities assumed. If the sum of this consideration and other items is lower than the fair value of the net assets acquired, the difference is, after reassessment, recognized in profit or loss as a gain on bargain purchase.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.3     Business combination (Continued)

(b)     Acquisition method of accounting for other business combinations and goodwill (Continued)

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. Goodwill is tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying value may be impaired. The Group performs its annual impairment test of goodwill as of December 31,. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group's cash-generating units, or groups of cash-generating units, that are expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the Group are assigned to those units or groups of units.

Impairment is determined by assessing the recoverable amount of the cash-generating unit (group of cash- generating units) to which the goodwill relates. Where the recoverable amount of the cash-generating unit (group of cash-generating units) is less than the carrying amount, an impairment loss is recognized. An impairment loss recognized for goodwill is not reversed in a subsequent period.

Where goodwill has been allocated to a cash-generating unit (or group of cash-generating units) and part of the operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on the disposal. Goodwill disposed of in these circumstances is measured based on the relative value of the operation disposed of and the portion of the cash-generating unit retained.

2.4     Separate financial statements

Investments in subsidiaries are accounted for at cost less impairment. Cost includes direct attributable costs of investment. The results of subsidiaries are accounted for by the Company on the basis of dividend received and receivable.

Impairment testing of the investments in subsidiaries is required upon receiving a dividend from these investments if the dividend exceeds the total comprehensive income of the subsidiary in the period the dividend is declared or if the carrying amount of the investment in the separate financial statements exceeds the carrying amount in the consolidated financial statements of the investee’s net assets including goodwill.

2.5     Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision-makers, who are responsible for allocating resources and assessing the performance of the operating segments, have been identified as the executive presidents committee of the Company that make strategic decisions.

2.6     Foreign currency translation

(a)      Functional and presentation currency

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (‘the functional currency’). The consolidated financial statements are presented in RMB, which is the Company’s functional and presentation currency.

(b)     Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates are generally recognized in profit or loss.

Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation differences on assets and liabilities carried at fair value are reported as part of the fair value gain or loss. For example, translation differences on non-monetary assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the fair value gain or loss and translation differences on non-monetary assets such as equities classified as fair value through other comprehensive income are recognized in other comprehensive income.

(c)      Group companies

The results and financial positions of all the group entities (none of which has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

(i) assets and liabilities in each statement of financial position presented are translated at the closing rates at the end of the reporting period;

(ii) income and expenses in each statement of profit and loss and other comprehensive income are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rates at the dates of the transactions); and

(iii) all resulting exchange differences are recognized in other comprehensive income.

Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the closing rate.

2.6     Foreign currency translation (Continued)

(d)      Disposal of foreign operation and partial disposal

On the disposal of a foreign operation (that is, a disposal of the group’s entire interest in a foreign operation, or a disposal involving loss of control over a subsidiary that includes a foreign operation, a disposal involving loss of joint control over a joint venture that includes a foreign operation, or a disposal involving loss of significant influence over an associate that includes a foreign operation), all of the currency translation differences accumulated in equity in respect of that operation attributable to the owners of the company are reclassified to profit or loss.

2.7     Property, plant and equipment

Property, plant and equipment, other than construction in progress, are stated at cost less accumulated depreciation and any impairment losses. When an item of property, plant and equipment is classified as held for sale or when it is part of a disposal group classified as held for sale, it is not depreciated and is accounted for in accordance with IFRS 5. Construction in progress represents buildings under construction, which is stated at cost less any impairment losses, and is not depreciated. The cost of an item of property, plant and equipment comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use.

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the group and the cost of the item can be measured reliably. The carrying amount of any component accounted for as a separate asset is derecognized when replaced. All other repairs and maintenance are charged to profit or loss during the reporting period in which they are incurred.

Depreciation is calculated using the straight-line method to allocate their cost or revalued amounts, net of their residual values, over their estimated useful lives as follows:

Buildings and infrastructure	8 – 45 years
Machinery	3 – 30 years
Transportation facilities	6 – 10 years
Office and other equipment	3 – 10 years

Residual values, useful lives and the depreciation method are reviewed, and adjusted if appropriate, at least at each financial year end.

Construction in progress (“CIP”) represents buildings under construction, which is stated at cost less any impairment losses, and is not depreciated. Cost comprises the direct costs of construction and capitalized borrowing costs on related borrowed funds during the period of construction. CIP is reclassified to the appropriate categories of property, plant and equipment when completed and ready for use.

An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount (Note 2.11).

Gains and losses on disposals are determined by comparing proceeds with carrying amount. These are included in profit or loss.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.8     Investment properties

Investment properties are interests in land use rights and buildings (including the leasehold property held as a right-of-use asset which would otherwise meet the definition of an investment property) held to earn rental income and/or for capital appreciation, rather than for use in the production or supply of goods or services or for administrative purposes; or for sale in the ordinary course of business. Such properties are measured initially at cost, including transaction costs. After initial recognition, the Group uses the cost methods to measure all of its investment properties.

Depreciation is calculated using the straight-line method to allocate their cost or revalued amounts, net of their residual values, over their estimated useful lives as follows:

Buildings	25 – 50 years
Land use rights	40 – 70 years

The carrying amounts of investment properties measured using the cost method are reviewed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable.

Any gains or losses on the retirement or disposal of an investment property are recognized in profit or loss in the year of the retirement or disposal.

2.9      Intangible assets

(a)      Goodwill

Goodwill is measured as described in Note 2.3. Goodwill on acquisitions of subsidiaries is included in intangible assets. Goodwill is not amortized but it is tested for impairment annually, or more frequently if events or changes in circumstances indicate that it might be impaired, and is carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill arose. The units or groups of units are identified at the lowest level at which goodwill is monitored for internal management purposes, being the operating segments (Note 5).

2.9      Intangible assets (Continued)

(b)      Mining rights and mineral exploration rights

The Group’s mineral exploration rights and mining rights relate to coal, bauxite and other mines.

(i) Recognition

Except for mineral exploration rights and mining rights acquired in a business combination, mineral exploration rights and mining rights are initially recorded at cost which includes the acquisition consideration, qualifying exploration and other direct costs. The mineral exploration rights are stated at cost less any impairment, and the mining rights are stated at cost less any amortization and impairment.

(ii) Reclassification

Mineral exploration rights are converted to mining rights when obtain mining rights certification, or technical feasibility and commercial viability of extracting a mineral resource are demonstrable, and are subject to amortization when commercial production has commenced.

The Group assesses the stage of each mine under construction to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the unique nature of each mine construction project. The Group considers various relevant criteria, such as completion of a reasonable period of testing of the mine and equipment, ability to produce in saleable form (within specifications) and ability to sustain ongoing production to assess when a mine is substantially complete and ready for its intended use.

(iii) Amortization

Mining rights other than coal mining rights are amortized on a straight-line basis over a shorter period of the mining right valid period and expected mining life. Estimated mineable periods of the majority of the mining rights range from 3 to 30 years.

Coal mining rights are amortized on a unit-of-production basis over the economically recoverable reserves evaluated based on the reserves estimated in accordance with the standards of the mine concerned.

(iv) Impairment

An impairment review is performed when there are indicators that the carrying amount of the mineral exploration rights and mining rights may exceed their recoverable amounts. To the extent that this occurs, the excess is fully provided as an impairment loss.

(c)      Computer software

Acquired computer software licences are capitalized on the basis of the costs incurred to acquire and bring to use specific software. These costs are amortized over their estimated useful lives, which do not exceed 10 years. Costs associated with maintaining computer software programmes are recognized as an expense as incurred.

(d)      Aluminum production quota

Historically the Group acquired aluminum production quotas from third parties as the license for certain newly developed aluminum production lines. Currently such aluminum production quotas have no definite legal or regulatory terms, and their residual values at the end of the lives of the production lines to which they are currently attached are very uncertain. Aluminum production quota are initially recorded at cost and subsequently states at cost less any amortization and impairment. Amortization is provided on a straight-line basis over expected useful life of related aluminum production lines.

2.10   Research and development costs

Research and development expenditures are classified as research expenditures and development expenditures according to the nature of the expenditures and whether there is significant uncertainty of development activities transforming to assets.

Research expenditures are recognized in profit or loss for the current period. Development expenditures are recognized as assets when all of the following criteria are met:

(i) it is technically feasible to complete the asset so that it will be available for use or sale;

(ii) management intends to complete the asset and intends and has the ability to use or sell it;

(iii) it can be demonstrated that the asset will generate probable future economic benefits;

(iv) there are adequate technical, financial and other resources to complete the development of the asset and management has the ability to use or sell the asset; and

(v) the expenditure attributable to the asset during its development phase can be reliably measured.

Development expenditures that do not meet the criteria above are recorded in profit or loss for the current period as incurred. Development expenditures that have been recorded in profit or loss in previous periods will be not recognized as assets in subsequent periods. The Group has not had any development expenditure capitalized.

2.11   Impairment of non-financial assets

Goodwill and intangible assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment, or more frequently if events or changes in circumstances indicate that they might be impaired. Other assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows which are largely independent of the cash inflows from other assets or groups of assets (cash-generating units). Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at the end of each reporting period.

2.12   Non-current assets (or disposal groups) held for sale

Non-current assets (or disposal groups) are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use and a sale is considered highly probable. They are measured at the lower of their carrying amount and fair value less costs to sell, except for assets such as deferred tax assets, assets arising from employee benefits, financial assets and investment property that are carried at fair value and contractual rights under insurance contracts, which are specifically exempt from this requirement.

An impairment loss is recognized for any initial or subsequent write-down of the asset (or disposal group) to fair value less costs to sell. A gain is recognized for any subsequent increases in fair value less costs to sell of an asset (or disposal group), but not in excess of any cumulative impairment loss previously recognized. A gain or loss not previously recognized by the date of the sale of the non-current asset (or disposal group) is recognized at the date of derecognition.

Non-current assets (including those that are part of a disposal group) are not depreciated or amortized while they are classified as held for sale. Interest and other expenses attributable to the liabilities of a disposal group classified as held for sale continue to be recognized.

Non-current assets classified as held for sale and the assets of a disposal group classified as held for sale are presented separately from the other assets in the balance sheet. The liabilities of a disposal group classified as held for sale are presented separately from other liabilities in the balance sheet.

2.13   Investments and other financial assets

(a)     Classification

The Group classifies its financial assets in the following measurement categories:

● those to be measured subsequently at fair value (either through OCI or through profit or loss), and

● those to be measured at amortized cost.

The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash flows.

Except for trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient of not adjusting the effect of a significant financing component, the Group initially measures a financial asset at its fair value, plus in the case of a financial asset not at fair value through profit or loss, transaction costs. Trade receivables and notes receivable that do not contain a significant financing component or for which the Group has applied the practical expedient are measured at the transaction price determined under IFRS 15 in accordance with the policies set out for “Revenue recognition” below.

For a financial asset to be classified and measured at amortized cost or fair value through other comprehensive income, it needs to give rise to cash flows that are solely payments of principal and interest (“SPPI”) on the principal amount outstanding. Financial assets with cash flows that are not SPPI are classified and measured at fair value through profit or loss, irrespective of the business model.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.13   Investments and other financial assets (Continued)

(a)     Classification (Continued)

The Group’s business model for managing financial assets refers to how it manages its financial assets to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both. Financial assets classified and measured at amortized cost are held within a business model with the objective to hold financial assets to collect contractual cash flows, while financial assets classified and measured at fair value through other comprehensive income are held within a business model with the objective of both holding to collect contractual cash flows and selling. Financial assets which are not held within the aforementioned business models are classified and measured at fair value through profit or loss.

All regular way purchases and sales of financial assets are recognized on the trade date, that is, the date that the Group commits to purchase or sell the asset. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the period generally established by regulation or convention in the market place.

(b)     Subsequent measurement

The subsequent measurement of financial assets depends on their classification as follows:

(i) Financial assets at amortized cost (debt instruments)

Financial assets at amortized cost are subsequently measured using the effective interest method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired.

(ii) Financial assets at fair value through other comprehensive income (debt instruments)

For debt investments at fair value through other comprehensive income, interest income, foreign exchange revaluation and impairment losses or reversals are recognized in profit or loss and computed in the same manner as for financial assets measured at amortized cost. The remaining fair value changes are recognized in other comprehensive income. Upon derecognition, the cumulative fair value change recognized in other comprehensive income is recycled to profit or loss.

(iii)Financial assets designated at fair value through other comprehensive income (equity investments)

Upon initial recognition, the Group can elect to classify irrevocably its equity investments as equity investments designated at fair value through other comprehensive income when they meet the definition of equity under IAS 32 Financial Instruments: Presentation and are not held for trading. The classification is determined on an instrument-by-instrument basis.

Gains and losses on these financial assets are never recycled to profit or loss. Dividends are recognized as other income in profit or loss when the right of payment has been established, it is probable that the economic benefits associated with the dividend will flow to the Group and the amount of the dividend can be measured reliably, except when the Group benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in other comprehensive income. Equity investments designated at fair value through other comprehensive income are not subject to impairment assessment.

2.13   Investments and other financial assets (Continued)

(b) Subsequent measurement (Continued)

(iv)Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are carried in the statement of financial position at fair value with net changes in fair value recognized in profit or loss.

This category includes derivative instruments, wealth management products and equity investments which the Group had not irrevocably elected to classify at fair value through other comprehensive income. Dividends on equity investments classified as financial assets at fair value through profit or loss are also recognized as other gains in profit or loss when the right of payment has been established, it is probable that the economic benefits associated with the dividend will flow to the Group and the amount of the dividend can be measured reliably.

A derivative embedded in a hybrid contract, with a financial liability or non-financial host, is separated from the host and accounted for as a separate derivative if the economic characteristics and risks are not closely related to the host; a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and the hybrid contract is not measured at fair value through profit or loss. Embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through profit or loss category.

A derivative embedded within a hybrid contract containing a financial asset host is not accounted for separately. The financial asset host together with the embedded derivative is required to be classified in its entirety as a financial asset at fair value through profit or loss.

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e., removed from the Group’s consolidated statement of financial position) when:

● the rights to receive cash flows from the asset have expired; or

● the Group has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a “pass-through” arrangement; and either (a) the Group has transferred substantially all the risks and rewards of the asset, or (b) the Group has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Group has transferred its rights to receive cash flows from an asset or has entered a pass-through arrangement, it evaluates if, and to what extent, it has retained the risk and rewards of ownership of the asset. When it has neither transferred nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, the Group continues to recognize the transferred asset to the extent of the Group’s continuing involvement. In that case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained.

Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay.

2.13   Investments and other financial assets (Continued)

(c) Impairment of financial assets

The Group recognizes an allowance for expected credit losses (“ECLs”) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Group expects to receive, discounted at an approximation of the original effective interest rate.The impact of COVID-19 on GDP and other key indicators have been considered when determining the severity and likelihood of downside economic scenarios that are used to estimate ECL under IFRS 9 in 2021.

General approach

ECLs are recognized in three stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12 months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL). For those have objective evidence of impairment at the reporting date, lifetime ECL are recognized and interest revenue is calculated on the net carrying amount.

At each reporting date, the Group assesses whether the credit risk on a financial instrument has increased significantly since initial recognition. When making the assessment, the Group compares the risk of a default occurring on the financial instrument as of the reporting date with the risk of a default occurring on the financial instrument as of the date of initial recognition and considers reasonable and supportable information that is available without undue cost or effort, including historical and forward-looking information.

The Group considers a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.

Debt investments at fair value through other comprehensive income and financial assets at amortized cost are subject to impairment under the general approach and they are classified within the following stages for measurement of ECLs except for trade receivables and contract assets which apply the simplified approach as detailed below.

Stage 1 - Financial instruments for which credit risk has not increased significantly since initial recognition and for which the loss allowance is measured at an amount equal to 12-month ECLs

Stage 2 - Financial instruments for which credit risk has increased significantly since initial recognition but that are not credit-impaired financial assets and for which the loss allowance is measured at an amount equal to lifetime ECLs

Stage 3 - Financial assets that are credit-impaired at the reporting date (but that are not purchased or originated credit-impaired) and for which the loss allowance is measured at an amount equal to lifetime ECLs

(c) Impairment of financial assets (Continued)

Simplified approach

For trade receivables, notes receivable and contract assets that do not contain a significant financing component or when the Group applies the practical expedient of not adjusting the effect of a significant financing component, the Group applies the simplified approach in calculating ECLs. Under the simplified approach, the Group does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. The Group has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

For trade receivables, notes receivable and contract assets that contain a significant financial component and lease receivables, the Group chooses as its accounting policy to adopt the simplified approach in calculating ECLs with policies as described above.

2.14   Financial liabilities

(a) Initial recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Group’s financial liabilities include trade and other payables, derivative financial instruments and interest-bearing bank and other borrowings.

(b) Subsequent measurement

The subsequent measurement of financial liabilities depends on their classification as follows:

(i) Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as of fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered by the Group that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments. Gains or losses on liabilities held for trading are recognized in profit or loss. The net fair value gain or loss recognized in profit or loss does not include any interest charged on these financial liabilities.

2.14   Financial liabilities (Continued)

(b)Subsequent measurement (Continued)

(ii) Financial liabilities at amortized cost (loans and borrowings)

After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost, using the effective interest rate method unless the effect of discounting would be immaterial, in which case they are stated at cost. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the effective interest rate amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. The effective interest rate amortization is included in finance costs in profit or loss.

(iii) Financial liabilities at amortized cost (trade and other payables)

These amounts represent liabilities for goods and services provided to the Group prior to the end of financial year which are unpaid. The amounts are unsecured and are usually paid within 30 days of recognition. Trade and other payables are presented as current liabilities unless payment is not due within 12 months after the reporting period. They are subsequently measured at amortized cost using the effective interest method.

(iv) Financial guarantee contracts

Financial guarantee contracts issued by the Group are those contracts that require a payment to be made to reimburse the holder for a loss it incurs because the specified debtor fails to make a payment when due in accordance with the terms of a debt instrument. A financial guarantee contract is recognized initially as a liability at its fair value, adjusted for transaction costs that are directly attributable to the issuance of the guarantee. Subsequent to initial recognition, the Group measures the financial guarantee contracts at the higher of: (i) the ECL allowance determined in accordance with the policy as set out in “Impairment of financial assets”; and (ii) the amount initially recognized less, when appropriate, the cumulative amount of income recognized.

(c) Derecognition of financial liabilities

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and a recognition of a new liability, and the difference between the respective carrying amounts is recognized in profit or loss.

2.15   Offsetting financial instruments

Financial assets and liabilities are offset and the net amount is reported in the balance sheet where the Group currently has a legally enforceable right to offset the recognized amounts, and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously.

2.16   Derivatives

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument. The Group’s derivative instruments do not qualify for hedge accounting. Changes in the fair value of any derivative instrument that does not qualify for hedge accounting are recognized immediately in profit or loss and are included in other gains/(losses).

2.17   Inventories

Raw materials and stores, work in progress and finished goods are stated at the lower of cost and net realizable value. Cost comprises direct materials, direct labour and an appropriate proportion of variable and fixed overhead expenditure, the latter being allocated on the basis of normal operating capacity. Costs are assigned to individual items of inventory on the basis of weighted average costs. Costs of purchased inventory are determined after deducting rebates and discounts. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

2.18   Cash and cash equivalents

For the purpose of presentation in the statement of cash flows, cash and cash equivalents includes cash on hand and demand deposits, and short term highly liquid investments that are readily convertible into known amounts of cash, are subject to an insignificant risk of changes in value, and have a short maturity of generally within three months when acquired, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities in the balance sheet.

2.19   Borrowing costs

General and specific borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to complete and prepare the asset for its intended use or sale. Qualifying assets are assets that necessarily take a substantial period of time to get ready for their intended use or sale.

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization.

Other borrowing costs are expensed in the period in which they are incurred.

2.20   Current and deferred income tax

The income tax expense or credit for the period is the tax payable on the current period’s taxable income based on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable to temporary differences and to unused tax losses.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.20   Current and deferred income tax (Continued)

Current income tax

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period in the countries where the Company and its subsidiaries and associates operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Group measures its tax balances either based on the most likely amount or the expected value, depending on which method provides a better prediction of the resolution of the uncertainty.

Deferred income tax

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill. Deferred income tax is also not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the end of the reporting period and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred tax assets are recognized only if it is probable that future taxable amounts will be available to utilize those temporary differences and losses.

Deferred tax liabilities and assets are not recognized for temporary differences between the carrying amount and tax bases of investments in foreign operations where the Company is able to control the timing of the reversal of the temporary differences and it is probable that the differences will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities and where the deferred tax balances relate to the same taxation authority. Current tax assets and tax liabilities are offset where the entity has a legally enforceable right to offset and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

Current and deferred tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

2.21   Employee benefits

Employee benefits mainly include salaries, bonuses, allowances and subsidies, pension insurance, social insurance and housing funds, labor union fees, employees’ education fees and other expenses related to the employees for their services. The Group recognizes employee benefits as liabilities during the accounting period when employees rendered the services and allocates the related cost of assets and expenses based on different beneficiaries.

2.21   Employee benefits (Continued)

(a) Bonus plans

The expected cost of bonus plans is recognized as a liability when the Group has a present legal or constructive obligation as a result of services rendered by employees and a reliable estimate of the obligation can be made.

(b) Retirement benefit obligations

The Group primarily pays contributions on a monthly basis to participate in a pension plan organised by the relevant municipal and provincial governments in the PRC. The municipal and provincial governments undertake to assume the retirement benefit obligations of all existing and future retired employees payable under these plans. The Group has no legal or constructive obligations for further contributions if the fund does not hold sufficient assets to pay all employees the benefit relating to their current and past services.

(c) In addition, the Company and its eligible subsidiaries have established an enterprise annuity plan in accordance with national policies and relevant requirements under the Company's system. Fees required for the enterprise annuity plan shall be jointly paid by the enterprise and its employees. Employees may elect to join or not to join the enterprise annuity plan on voluntary basis.

As of December 31, 2021, the Group had no forfeited contributions available to offset contributions payable in future years. For the year ended December 31, 2021, the Group did not have any defined benefit plan.

(d) Other social insurance and housing funds

The Group provides other social insurance and housing funds to the qualified employees in the PRC based on certain percentages of their salaries. These percentages are not to exceed the upper limits of the percentages prescribed by the Ministry of Human Resources and Social Security of the PRC. These benefits are paid to social security organizations and the amounts are expensed as incurred. The Group has no legal or constructive obligations for further contributions if the fund does not hold sufficient assets to pay all employees the benefit relating to their current and past services.

(e) Termination benefit obligations

Termination benefit obligations are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognizes termination benefit obligations when it is demonstrably committed to either: terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal; or providing termination benefits as a result of an offer made to encourage voluntary redundancy. The specific terms vary among the terminated employees depending on various factors including position, length of service and district of the employees concerned. Benefits falling due for more than 12 months after the end of the reporting period are discounted to their present values.

2.22   Provisions

Provisions for legal claims, asset retirement obligations are recognized when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation and the amount can be reliably estimated. Provisions are not recognized for future operating losses.

Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognized even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

Provisions are measured at the present value of management’s best estimate of the expenditure required to settle the present obligation at the end of the reporting period. The discount rate used to determine the present value is a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The increase in the provision due to the passage of time is recognized as interest expense.

2.23   Revenue recognition

Revenue from contracts with customers

Revenue from contracts with customers is recognized when control of goods or services is transferred to the customers at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods or services.

When the consideration in a contract includes a variable amount, the amount of consideration is estimated to which the Group will be entitled in exchange for transferring the goods or services to the customer. The variable consideration is estimated at contract inception and constrained until it is highly probable that a significant revenue reversal in the amount of cumulative revenue recognized will not occur when the associated uncertainty with the variable consideration is subsequently resolved.

When the contract contains a financing component which provides the customer with a significant benefit of financing the transfer of goods or services to the customer for more than one year, revenue is measured at the present value of the amount receivable, discounted using the discount rate that would be reflected in a separate financing transaction between the Group and the customer at contract inception. When the contract contains a financing component which provides the Group a significant financial benefit for more than one year, revenue recognized under the contract includes the interest expense accreted on the contract liability under the effective interest method. For a contract where the period between the payment by the customer and the transfer of the promised goods or services is one year or less, the transaction price is not adjusted for the effects of a significant financing component, using the practical expedient in IFRS 15.

(a) Sale of industrial products

Revenue from the sale of industrial products (including sales of scrap and other materials) is recognized at the point in time when control of the asset is transferred to the customer, generally on delivery of the industrial products. Revenue from electricity is recognized upon transmission of electricity based on the confirmation from the power grid.

(b) Rendering of services

The Group provides transportation service and the revenue from services is recognized over time, using an input method to measure progress towards complete satisfaction of the service, because the customer simultaneously receives and consumes the benefits provided by the Group.

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.24   Earnings per share

(a) Basic earnings per share

Basic earnings per share is calculated by dividing:

● the profit attributable to owners of the Company, excluding any costs of servicing equity other than ordinary shares;

● by the weighted average number of ordinary shares outstanding during the financial year, adjusted for bonus elements in ordinary shares issued during the year and excluding treasury shares.

(b) Diluted earnings per share

Diluted earnings per share adjusts the figures used in the determination of basic earnings per share to take into account:

● the after-income tax effect of interest and other financing costs associated with dilutive potential ordinary shares, and

● the weighted average number of additional ordinary shares that would have been outstanding assuming the conversion of all dilutive potential ordinary shares.

2.25   Dividend income

Dividend income is recognized when the shareholders' right to receive payment has been established, it is probable that the economic benefits associated with the dividend will flow to the Group and the amount of the dividend can be measured reliably.

2.26   Leases

Leases are recognized as a right-of-use asset and a corresponding liability at the date which the leased asset is available for use by the Group.

Contracts may contain both lease and non-lease components. The Group allocates the consideration in the contract to the lease and non-lease components based on their relative stand-alone prices. However, for leases of real estate for which the Group is a lessee, it has elected not to separate lease and non-lease components and instead accounts for these as a single lease component.

Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. The lease agreements do not impose any covenants other than the security interests in the leased assets that are held by the lessor. Leased assets may not be used as security for borrowing purposes.

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments:

● fixed payments (including in-substance fixed payments), less any lease incentives receivable;

2        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

2.26   Leases (Continued)

● variable lease payment that are based on an index or a rate, initially measured using the index or rate as of the commencement date;

● amounts expected to be payable by the Group under residual value guarantees;

● the exercise price of a purchase option if the Group is reasonably certain to exercise that option, and

● payments of penalties for terminating the lease, if the lease term reflects the Group exercising that option.

Lease payments to be made under reasonably certain extension options are also included in the measurement of the liability.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, which is generally the case for leases in the Group, the lessee’s incremental borrowing rate is used, being the rate that the individual lessee would have to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment with similar terms, security and conditions.

To determine the incremental borrowing rate, the Group:

● where possible, uses recent third-party financing received by the individual lessee as a starting point, adjusted to reflect changes in financing conditions since third party financing was received;

● uses a build-up approach that starts with a risk-free interest rate adjusted for credit risk for leases held by the Group, which does not have recent third-party financing, and,

● makes adjustments specific to the lease, eg term, country, currency and security.

If a readily observable amortizing loan rate is available to the individual lessee (through recent financing or market data) which has a similar payment profile to the lease, then the Group entities use that rate as a starting point to determine the incremental borrowing rate.

The Group is exposed to potential future increases in variable lease payments based on an index or rate, which are not included in the lease liability until they take effect. When adjustments to lease payments based on an index or rate take effect, the lease liability is reassessed and adjusted against the right-of-use asset.

Lease payments are allocated between principal and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

Right-of-use assets are measured at cost comprising the following:

● the amount of the initial measurement of lease liability;

● any lease payments made at or before the commencement date less any lease incentives received;

● any initial direct costs, and

2.26   Leases (Continued)

● restoration costs.

Right-of-use assets are generally depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis as follows:

Buildings	2 – 20 years
Machinery	2 – 10 years
Land use rights	10 – 50 years

If the Group is reasonably certain to exercise a purchase option, the right-of-use asset is depreciated over the underlying asset’s useful life. While the Group revalues its land and buildings that are presented within property, plant and equipment, it has chosen not to do so for the right-of-use buildings held by the Group.

Payments associated with short-term leases of equipment and vehicles and all leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss. The Group applies the short-term lease recognition exemption to its short-term leases of machinery and equipment (that is those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the recognition exemption for leases of low-value assets to leases of office equipment that are considered to be of low value (i.e. below RMB30,000).

Rental income

Rental income is recognized on a time proportion basis over the lease terms. Variable lease payments that do not depend on an index or a rate are recognized as income in the accounting period in which they are incurred.

2.27   Dividend distribution

Provision is made for the amount of any dividend declared, being appropriately authorized and no longer at the discretion of the entity, on or before the end of the reporting period but not distributed at the end of the reporting period.

2.28   Government grants

Government grants are recognized at their fair value where there is reasonable assurance that the grant will be received and all attaching conditions will be complied with. When the grant relates to an expense item, it is recognized as income on a systematic basis over the periods that the costs, which it is intended to compensate, are expensed.

Asset-related government grants are recognized when the government document designates that the government grants are used for constructing or forming long-term assets. If the government document is inexplicit, the Group should make a judgement based on the basic conditions to obtain the government grants, and recognize them as asset-related government grants if the conditions are to construct or to form long-term assets. Otherwise, the government grants should be income-related.

2.28   Government grants (Continued)

For asset-related government grants that is related to long lived assets that already exist at the time of recognizing the government grant, the grant is deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduced depreciation expense. If the asset is not yet purchased or constructed at the time of recognizing the government grant, the grant is recognized as deferred income and will be deducted from the cost of the asset once the asset is recognized.

Income-related government grants that are specific to compensate expenses or costs that have already incurred, they are directly recognized in profit or loss for the current period as deduction of the related expenses or costs. If the income-related government grants are specific to compensate future expenses or costs of the Group, they are recognized as deferred income and will be released to profit or loss when the related expenses or costs are incurred.

2.29   Interest income

Interest income from financial assets at FVPL is included in the net fair value gains/(losses) on these assets. Interest income on financial assets at amortized cost and financial assets at FVOCI calculated using the effective interest method is recognized in profit or loss as part of other income. Interest income is presented as finance income where it is earned from financial assets that are held for cash management purposes. Any other interest income is included in other income.

Interest income is calculated by applying the effective interest rate to the gross carrying amount of a financial asset except for financial assets that subsequently become credit-impaired. For credit-impaired financial assets the effective interest rate is applied to the net carrying amount of the financial asset (after deduction of the loss allowance).

3        SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES

The preparation of the Group’s consolidated financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. Uncertainty about these judgements, assumptions and estimates could result in outcomes that require a material adjustment to the carrying amounts of assets or liabilities affected in future periods.

Judgements

In the process of applying the Group’s accounting policies and preparing the Group’s consolidated financial statements, management has made the following judgements, apart from those involving estimates, which have a significant effect on the amounts recognized in the consolidated financial statements.

(a) Significant influence over an entity in which the Group holds less than 20% of voting rights

As of December 31, 2021, the Group owned a 6.68% equity interest in China Copper Mineral Resources Co.,Ltd. (“Chalco Resources”) (中銅礦產資源有限公司). The Group considers that it has significant influence over Chalco Resources even though it owns less than 20% of the voting rights, on the grounds that the Group can appoint one out of the five directors of the Board of Directors of Chalco Resources, thus have the right to participate in decision making of Chalco Resources.

Judgements (Continued)

(a) Significant influence over an entity in which the Group holds less than 20% of voting rights (Continued)

As of December 31, 2021, the Group owned a 16% equity interest in Baise New Aluminum Power Co., Ltd. (“New Aluminum Power”) (百色新鋁電力有限公司). The Group considers that the Group has significant influence over New Aluminum Power even though it owns less than 20% of the voting rights, on the grounds that the Group can appoint one out of the nine directors of the Board of Directors of New Aluminum Power, thus have the right to participate in decision making of New Aluminum Power.

As of December 31, 2021, the Group owned 14.71% of the voting right of Chinalco Capital Holdings Co., Ltd. (“Chinalco Capital”) (中鋁資本控股有限公司).

(“China Resources Coal Industry”), China Resources Coal Industry would exercise the shareholders’ and Board of Directors’ votes in concert with the Group. Therefore, the directors of the Company believe that the Company has control over Shanxi Zhongrun and consolidated Shanxi Zhongrun’s financial statements from the date the Group obtained control.

Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Group’s assumptions and estimates are based on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising beyond the control of the Group. Such changes are reflected in the assumptions when they occur.

(a) Impairment assessment of property, plant and equipment

As of December 31, 2021, the Group’s net carrying amount of property, plant and equipment (“PP&E”) was RMB93,427 million. Management assesses related assets for potential impairment whenever there are indications that the carrying value of an asset or a group of assets may not be recoverable. As of December 31, 2021, management performed impairment assessment on property, plant and equipment (“PP&E”) with impairment indications at the level of cash generating unit (“CGU”) to which the PP&E was allocated using discounted cash flow model. The discounted cash flows model used for the impairment assessment of PP&E involved significant assumptions including product prices and the discount rate. Based on the impairment test, RMB2,328 million of impairment was recognized by management for PP&E for the year ended December 31, 2021.

3        SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES (CONTINUED)

Estimates and assumptions (Continued)

(b) Impairment assessment of goodwill

As of December 31, 2021, the Group’s carrying value of goodwill was RMB3,510 million. Management performed impairment assessment of goodwill on an annual basis. When performing the impairment assessment, the recoverable amount of the CGU to which the goodwill was allocated was estimated by management using discounted cash flow model, and compared with the carrying amount of the CGU to determine if goodwill was impaired. The discounted cash flow models used for the impairment assessment of goodwill involved significant assumptions including product prices, the long-term growth rate and the discount rate. Based on the impairment test, no impairment provision is required for goodwill for the year ended December 31, 2021.

(c) Property, plant and equipment and intangible assets (excluding goodwill) – estimated useful lives and residual values

The Group’s management determines the estimated useful lives and residual values (if applicable) and consequently the related depreciation/amortization charges for its property, plant and equipment and intangible assets (excluding goodwill). These estimates are based on the historical experience of the actual useful lives of property, plant and equipment of similar nature and functions, or based on the useful life of intangible assets. Management will increase the depreciation/amortization charge where useful lives are less than previously estimated, and it will write off or write down technically obsolete or non-strategic assets that have been abandoned or sold.

Actual economic lives may differ from estimated useful lives and actual residual values may differ from estimated residual values. Periodic review could result in change in depreciable lives and residual values and therefore change in depreciation/amortization expense in future periods.

(d) Coal reserve estimates and units-of-production amortization for coal mining rights

External qualified valuation professionals evaluate “economically recoverable reserves” based on the reserves estimated by external qualified exploration engineers in accordance with the PRC standards. The estimates of coal reserves are inherently imprecise and represent only the approximate amounts of the coal reserves because of the subjective judgements involved in developing such information. Economically recoverable reserve estimates are evaluated on a regular basis and have taken into account recent production and technical information about each mine.

(e) Estimated net realizable value of inventories

In accordance with the Group’s accounting policy, the Group’s management estimated net realizable value of inventories based on specific facts and circumstances. For different types of inventories, it requires the estimation on selling prices, costs of conversion, selling expenses and the related tax expense to calculate the net realizable amount of inventories. For inventories held for executed sales contracts, management estimates the net realizable amount based on the contracted price. For raw materials and work-in-progress, management has established a model in estimating the net realizable amount at which the inventories can be realized in the normal course of business after considering the Group’s manufacturing cycles, production capacity and forecasts, estimated future conversion costs and selling prices. Management also takes into account the price or cost fluctuations and other related matters occurring after the end of the reporting period which reflect conditions that existed at the end of the reporting period.

It is reasonably possible that if there is a significant change in circumstances including the Group’s business and the external environment, outcomes within the next financial year would be significantly affected.

3        SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES (CONTINUED)

Estimates and assumptions (Continued)

(f) Investments in joint ventures and associates – recoverable amount

In accordance with the Group’s accounting policy, each investment in a joint venture and an associate is evaluated in every reporting period to determine whether there are any indicators of impairment. If any such indicators exists, an estimate of the recoverable amount is performed and an impairment loss is recognized to the extent that the carrying amount exceeds the recoverable amount. The recoverable amount of the investment in a joint venture and an associate is measured at the higher of fair value less costs of disposal and value in use.

A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

Value in use is also generally determined as the present value of the estimated future cash flows of those expected to arise from the continued use of the asset in its present form and its eventual disposal. Present values are determined using a risk-adjusted pre-tax discount rate appropriate to the risks inherent in the asset. Future cash flow estimates are based on expected production and sales volumes, commodity prices (considering current and historical prices, price trends and related factors) and operating costs. This policy requires management to make these estimates and assumptions which are subject to risk and uncertainty; hence there is a possibility that changes in circumstances will alter these projections, which may impact on the recoverable amounts of the investments. In such circumstances, some or all of the carrying value of the investments may be impaired and the impairment would be charged against profit or loss.

(g) Determination of the lease term

The Group leased certain land use rights from Chinalco for operation use. Pursuant to the framework lease contract entered into between the Company and Chinalco in 2001, the lease term is 50 years from July 1, 2001 with a termination option entitled to the Company. Under this framework contract, the related branches and subsidiaries of the Group signed lease agreements annually respectively with subsidiaries of Chinalco which owns the related land use right, with the extension option entitled to the leasees.

The lease term is determined based on the Group's assessment if the related termination option or extension option would be reasonably exercised taking into account the use of the land and operating status. The Group will reassess the lease term if any significant events or changes in circumstances that may have impact on the exercise of such options and are under the control of the Group occurred.

(h) Income tax

The Group estimates its income tax provision and deferred taxation in accordance with the prevailing tax rules and regulations, taking into account any special approvals obtained from the relevant tax authorities and any preferential tax treatment to which it is entitled in each location or jurisdiction in which the Group operates. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Group recognizes liabilities for anticipated tax audit issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, the differences will impact on the income tax and deferred tax provisions in the period in which the determination is made.

3        SIGNIFICANT ACCOUNTING JUDGEMENTS AND ESTIMATES (CONTINUED)

Estimates and assumptions (Continued)

(h) Income tax (Continued)

Deferred tax assets are recognized for unused tax losses and deductible temporary differences, such as the provision for impairment of receivables, inventories and property, plant and equipment and accruals of expenses not yet deductible for tax purposes, to the extent that it is probable that taxable profits will be available against which the losses deductible temporary difference can be utilized.

An entity shall recognize a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates, and joint ventures, except to the extent that both of the following conditions are satisfied:

● the parent, investor or joint venture is able to control the timing of the reversal of the temporary difference; and

● it is probable that the temporary difference will not reverse in the foreseeable future.

In the event that future tax rules and regulations or related circumstances change, adjustments to current and deferred taxation may be necessary which would impact on the Group’s results or financial position.

(i) Impairment of receivables

The loss allowances for receivables are based on assumptions about risk of default and expected loss rates to determine the expected loss. The Group uses judgement in making these assumptions and selecting the inputs to the impairment calculation, based on the Group’s history, existing market conditions as well as forward looking estimates at the end of each reporting period.

The Group takes into account different macroeconomic scenarios in considering forward looking information. The Group regularly monitors and reviews the key macroeconomic assumptions and parameters related to the calculation of expected credit losses, including the risk of economic downturn, external market environment, technological environment, changes in customer conditions, GDP and consumer price index, etc. During the year ended December 31, 2021, the Group has taken into account the uncertainties arising from the COVID-19 outbreak and updated the relevant assumptions and parameters accordingly. The key macroeconomic parameters are listed below:

		Scenarios

The executive presidents committee of the Company have been identified as the chief operating decision makers. The committee is responsible for the review of the internal reports in order to allocate resources to operating segments and assess their performance.

The committee considers the business from a product perspective comprising alumina, primary aluminum and energy for the Group’s manufacturing business, which are identified as separate reportable operating segments. In addition, the Group’s trading business is identified as a separate reportable operating segment. The Group’s reportable operating segments also include corporate and other operating segments.

The committee assesses the performance of operating segments based on profit or loss before income tax in related periods. The manner of assessment used by the committee is consistent with that applied to the consolidated financial information for the year ended December 31, 2020. Management has determined the reportable operating segments based on the reports reviewed by the committee that are used to make strategic decisions.

The Group’s five reportable operating segments are summarized as follows:

● The alumina segment, which consists of mining and purchasing bauxite and other raw materials, refining bauxite into alumina, and selling alumina both internally to the Group’s aluminum enterprises and trading enterprises and externally to customers outside the Group. This segment also includes the production and sale of multi-form alumina bauxite.

● The primary aluminum segment, which consists of procuring alumina and other raw materials, supplemental materials and electricity power, smelting alumina to produce primary aluminum which is sold to the Group’s trading enterprises and external customers, including Chinalco and its subsidiaries. This segment also includes the production and sale of carbon products and aluminum alloy and other aluminum products.

6       INTANGIBLE ASSETS (CONTINUED)

For the years ended December 31, 2019, 2020 and 2021, the amortization expenses of intangible assets recognized in profit or loss were analyzed as follows:

	For the years ended December 31
	2019	2020	2021
Cost of sales	294,766	371,616	305,484
General and administrative expenses	44,172	87,866	72,230
	338,938	459,482	377,714

As of December 31 2021, the Group pledged mining rights and mineral exploration rights with a net carrying value amounting to RMB1,400 million (December 31, 2020: RMB960 million) for interest-bearing loans and borrowings as set out in Note 24.

Impairment testing of goodwill

The lowest level within the Group at which goodwill is monitored for internal management purposes is the operating segment before aggregation. Therefore, goodwill is allocated to the Group’s CGUs and groups of CGUs that are expected to benefit from the synergies of the relevant business combination. A summary of goodwill allocation is presented below:

	December 31, 2021		December 31, 2020
	Alumina	Primary aluminum	Alumina	Primary aluminum
Qinghai Branch	—	217,267	—	217,267
Guangxi Branch	189,419	—	189,419	—
Lanzhou Aluminum Co., Ltd.	—	1,924,259	—	1,924,259
PT. Nusapati Prima (“PTNP“)	14,621	—	14,963	—
Shanxi Huaxing	1,163,949	—	1,163,949	—
	1,367,989	2,141,526	1,368,331	2,141,526

The recoverable amount of a CGU is determined based on value-in-use calculations. These calculation of VIU use pre-tax cash flow projections based on financial budgets approved by management covering a five-year period. Cash flows beyond the 5-year period are extrapolated using the estimated growth rate of 2% (2020: 2%) not exceeding the long-term average growth rate for the businesses in which the CGU operates. Other key assumptions applied in the impairment testing include future prices of aluminum and alumina and the discount rate. Management determined these key assumptions based on past performance and their expectations on market development. Furthermore, the Group adopts a nominal pre-tax rate of 12.62% (2020: 12.62%) that reflects specific risks related to CGUs and groups of CGUs and an underlying inflation rate of 2%  as the discount rate. The assumptions above are used in analyzing the recoverable amounts of CGUs and groups of CGUs within operating segments. These estimates and judgments may be affected by unexpected changes in the future market or economic conditions.

Based on their assessment, there was no impairment of goodwill as of December 31, 2021 and December 31, 2020.

7       PROPERTY, PLANT AND EQUIPMENT (CONTINUED)

For the year ended December 31, 2019, 2020 and 2021, depreciation expenses recognized in profit or loss are analyzed as follows:

	For the years ended December 31
	2019	2020	2021
	(Restated)	(Restated)
Cost of sales	6,936,008	6,877,532	6,998,349

Selling and distribution expenses	6,607	5,135	8,168
	7,106,765	7,161,476	7,375,559

As of December 31, 2021, the Group was in the process of applying for the ownership certificates of buildings with a net carrying value of RMB6,609 million (December 31, 2020: RMB7,616 million). There has been no litigations, claims or assessments against the Group for compensation with respect to the use of these buildings as of the date of approval of these financial statements.

For the year ended December 31, 2021, interest expenses of RMB2 million (2020: RMB124 million, 2019: RMB289 million) (Note 29) arising from borrowings attributable to the construction of property, plant and equipment during the year were capitalized at an annual rate of 4.00% (2020: 4.00% to 6.68%, 2019: 4.00% to 6.96)% (Note 29), and were included in additions to property, plant and equipment.

As of December 31, 2021, the Group pledged property, plant and equipment with a net carrying value amounting to RMB5,111 million (December 31, 2020: RMB5,191 million) for interest-bearing loans and borrowings as set out in Note 24.

As of December 31, 2021, the carrying value of temporarily idle property, plant and equipment of the Group was RMB723 million (December 31, 2020: RMB750 million).

Impairment testing for property, plant and equipment

As of December 31, 2021, certain CGUs of the Group are discontinued or in status of temporarily idle or insufficient utilization of capacity, due to the adjustment of overall production allocation within the Group or other specific adverse changes in circumstances related to the respective CGUs. The Group considered these CGUs had impairment indications and therefore performed impairment test on them. As a result, provision of impairment of RMB2,328 million was made for property, plant and equipment for the year ended December 31, 2021.

When any indicators of impairment are identified, property, plant and equipment are reviewed for impairment based on each CGU. The CGU is an individual plant or entity. The carrying values of these individual plants or entities were compared to the recoverable amounts of the CGUs, which were based predominantly on value-in-use. Value-in-use calculations use pre-tax cash flow projections based on financial budgets approved by management covering a five-year period. Cash flows beyond the five-year period are extrapolated using the same cash flow projections of the fifth year. Other key assumptions applied in the impairment testing include the future prices of aluminum and alumina, expected production and sales volumes, production costs and operating expenses. Management determined these key assumptions based on past performance and their expectations on market development. Further, the Group adopts a real pre-tax rate (excluding inflation) of 10.16% to 11.91% (2020: 10.16%) that reflects specific risks related to the CGUs as discount rate. The assumptions above are used in analyzing the recoverable amounts of the CGUs within operating segments. These estimates and judgments may be affected by unexpected changes in the future market or economic conditions.

As of December 31, 2021, other than trade and notes receivables amounting to RMB512 million which were denominated in USD (December 31,2020: RMB685 million which were denominated in USD), all other trade and notes receivables were denominated in RMB.

Trade and notes receivables due from the Group’s joint ventures and associates amounted to RMB641 million (December 31, 2020: RMB741 million) and RMB11 million (December 31, 2020: RMB14 million) respectively, which are repayable on credit terms similar to those offered to the major customers of the Group.

As of December 31, 2021, the Group pledged trade and notes receivable amounting to RMB1,983 million (December 31, 2020: RMB2,748 million) as set out in Note 24 to the financial statements.

Trade receivables and notes receivable are non-interest bearing and generally with credit terms of 3 to 12 months. Certain of the Group’s sales were on advance payments or documents against payment. In some cases, these terms are extended for qualifying long term customers that have met specific credit requirements. As of December 31, 2021, the ageing analysis of trade receivables based on invoice date was as follows:

	As of December 31
	2021	2020
		(Restated)
Within 1 year	2,367,787	2,984,665

Less: loss allowance for impairment	(958,787)	(933,890)
	3,066,654	4,753,210

An impairment analysis is performed at each reporting date using a provision matrix to measure expected credit losses. The provision rates are based on days past due for groupings of various customer segments with similar loss patterns (i.e., by geographical region, product type, customer type and rating, and coverage by letters of credit or other forms of credit insurance). The calculation reflects the probability-weighted outcome, the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. The Group also assesses impairment loss individually if there is evidence of significant increases in credit risk at an individual level.

	For the years ended December 31
	2019	2020	2021
	(Restated)	(Restated)
Profit attributable to owners of the Company (in thousands of RMB)	595,643	764,306	5,079,562
Adjustment: cumulative distribution reserved of other equity instruments (in thousands of RMB)	(219,249)	(261,168)	(209,500)
Adjusted profit attributable to ordinary shares holders of the Company	376,394	503,138	4,870,062

For the purpose of calculating basic earnings per share, the Group adjusted the profit attributable to owners of the Company by deducting the after-tax amounts of cumulative distribution reserved for the year for other equity instruments, which were issued by the Group and classified as equity instrument (Note 41).

Number of ordinary shares in issue (thousands) as of January 1	14,903,798	17,022,673	17,022,673
Issuance of share capital (thousands)	2,118,875	—	—

Basic earnings per share (RMB)	0.022	0.030	0.286

The Group had no potentially dilutive ordinary shares in issuance during the years ended December 31, 2021, 2020 and 2019, thus the diluted earnings per share were the same as basic earnings per share.

Basic earnings per share was calculated by dividing the adjusted profit attributable to ordinary shares holders of the Company by the weighted average number of shares in issue during the year.

34      DIVIDENDS

According to the articles of association of the Company, the Company considers the maximum limit of profit appropriation to its shareholders is the lowest of:

(i) the sum of the net profit less statutory surplus reserve and the opening retained earnings for the current period in accordance with IFRSs;

37      FINANCIAL AND CAPITAL RISK MANAGEMENT

37.1   Financial risk management

The Group’s activities expose it to a variety of financial risks, including market risk (including foreign currency risk, interest rate risk and commodity price risk), credit risk and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize the potential adverse effects on the Group’s financial performance.

Risk management is carried out by the treasury management department (the “Group Treasury”) under policies approved by the Board of Directors of the Company. The Group Treasury identifies, evaluates and hedges financial risks through close cooperation with the Group’s operating units.

(a)      Market risk

(i)      Foreign currency risk

The Group’s foreign currency risk arose from transaction conducted in currency other than the functional currency of the group entities. The Group’s foreign currency risk primarily arises from foreign currency deposits, trade receivables, trade payables and short-term and long-term loans denominated in United States dollars (“USD”), Euro (“EUR”), Japanese yen (“JPY”), and Hong Kong dollars (“HKD”). Related exposures are disclosed in Notes  16, 14, 23, 15 and 19 to the financial statements, respectively. The Group Treasury closely monitors the international foreign currency market on the change of exchange rates and takes these into consideration when investing in foreign currency deposits and borrowing loans. As of December 31, 2021, the Group only had significant exposure to USD.

As of December 31, 2021, if RMB had strengthened/weakened by 5% against USD with all other variables held constant, the profit for the year would have been approximately RMB28 million higher/lower (2020: RMB74 million higher/lower), mainly as a result of foreign exchange gains and losses arising from translation of USD denominated borrowings, other payables and medium term notes.

As the assets and liabilities denominated in other foreign currencies other than USD were relatively minimal to the total assets and liabilities of the Group, the directors of the Company are of the opinion that the Group was not exposed to significant foreign currency risk arising from other assets and liabilities denominated in currency other than the functional currency of the group entities as of December 31, 2021 and 2020.

37      FINANCIAL AND CAPITAL RISK MANAGEMENT (CONTINUED)

37.1   Financial risk management (Continued)

(a)      Market risk (Continued)

(ii)     Interest rate risk

As of December 31, 2021 and 2020, as the Group had no significant interest-bearing assets or liabilities except for bank deposits (Note 16), entrusted loans (Note 15) and Interest-bearing loans (Note 19).

Most of the bank deposits are maintained in savings and time deposit accounts in the PRC. The interest rates are regulated by the People’s Bank of China and the Group Treasury closely monitors the fluctuation on such rates periodically. The interest rates of entrusted loans are fixed. As the interest rates applied to the entrusted loans were fixed, the directors of the Company are of the opinion that the Group was not exposed to any significant interest rate risk for its financial assets held as of December 31, 2021 and 2020.

The interest rate risk for the Group’s financial liabilities primarily arises from interest-bearing loans. Loans borrowed at floating interest rates expose the Group to cash flow interest rate risk. The Group enters into debt obligations to support general corporate purposes including capital expenditures and working capital needs. The Group Treasury closely monitors market interest rates and maintains a balance between variable rate and fixed rate borrowings in order to reduce the exposures to the interest rate risk described above.

As of December 31, 2021, if interest rates had been 100 basis points (December 31, 2020: 100 basis points) higher/lower for bank and other loans borrowed at floating interest rates with all other variables held constant, net profit for the year would have been RMB421 million lower/higher (2020: RMB430 million), respectively, mainly as a result of the higher/ lower interest expense on floating rate borrowings.

The fair value interest rate risk of the Group mainly arises from medium term notes and short term bonds issued at fixed rates. As the fluctuation of comparable interest rates of corporate bonds with similar terms was relatively low, the directors of the Company are of the opinion that the Group was not exposed to any significant fair value interest rate risk for its fixed interest rate borrowings held as of December 31, 2021 and 2020.

(iii)    Commodity price risk

The Group uses futures and option contracts to reduce its exposure to fluctuations in the price of primary aluminum and other products. The Group uses the futures contract for offsetting other than speculation. With reference to the hedging of primary aluminum, production company hedges the output of primary aluminum and trading company hedges the quantities of buyout and self-supporting.

The Group uses mainly futures contracts and option contracts traded on the Shanghai Futures Exchange and London Metal Exchange (“LME”) to hedge against fluctuations in primary aluminum prices. As of December 31, 2021, the fair values of the outstanding futures contracts amounting to RMB0 million (December 31, 2020: RMB17 million) and RMB69 million (December 31, 2020: RMB27 million) were recognized in financial assets and financial liabilities at fair value through profit or loss, respectively.

As of December 31, 2021, if the commodity futures prices had increased/ decreased by 3% (December 31, 2020: 3%) and all other variables held constant, profit for the year would have changed by the amounts shown below:

	December 31, 2021	December 31, 2020
Primary aluminum	Decrease/increase RMB6 million	Decrease/increase  RMB5 million

37.1   Financial risk management (Continued)

(b)     Credit risk

Credit risk arises from balances with banks and financial institutions, trade and notes receivables, other current and non-current receivables as well as credit exposures of customers, including outstanding receivables and committed transactions.

The Group maintains substantially all of its bank balances and cash and short-term investments in several major state-owned banks in the PRC. With strong support from the PRC government to these state-owned banks, the directors of the Company are of the opinion that there is no significant credit risk on such assets being exposed to losses.

The Group applies the simplified approach to most of its trade receivables to provide for expected credit losses prescribed by IFRS 9, which permits the use of the lifetime expected loss provision for trade receivables. The Group has made individual assessment for trade receivables from clients with top rating and those receivables with pledged assets separately and impairment provisions are made.

To measure the expected credit losses of trade receivables other than those assessed individually as mentioned above, trade receivables have been grouped based on shared credit risk characteristics and the days past due. The expected credit loss model also incorporates forward-looking information.

For other current and non-current receivables, the Group considers the probability of default upon initial recognition of an asset and whether there has been a significant increase in credit risk on an ongoing basis throughout each reporting period. To assess whether there is a significant increase in credit risk the company compares the risk of a default occurring on the asset as of the reporting date with the risk of default as of the date of initial recognition. It considers available reasonable and supportive forwarding-looking information. Especially the following indicators are incorporated:

● internal credit rating

● external credit rating

● actual or expected significant adverse changes in business, financial or economic conditions that are expected to cause a significant change to the borrower’s ability to meet its obligations

● actual or expected significant changes in the operating results of individual clients

● significant changes in the expected performance and behavior of the clients

The Group measures expected credit loss rates on the basis of a loss rate approach by segmenting its portfolio into appropriate groupings based on shared credit risk characteristics. At the end of each year, the Group updates its historical loss information with forward-looking information. As the historical credit loss rates were comparatively stable and no significant changes were expected to the forward-looking information after the consideration of reasonable and supportable forecasts of comparatively stable customer relationship and customers’ credit ratings, the expected credit loss rates remained consistent during 2021.

The table below shows the credit quality and the maximum exposure to credit risk based on the Group’s credit policy, which is mainly based on past due information unless other information is available without undue cost or effort, and year-end staging classification as of December 31, 2021. The amounts presented are carrying amounts for financial assets and the exposure to credit risk for the financial guarantee contracts.

	Stage 1	Stage 2	Stage 3	Simplified	Total
Trade receivables	—	—	—	3,066,654	3,066,654

The carrying amounts of short-term investments and these receivables included in Notes 12, 14, 15 and 16 represent the Group’s maximum exposure to credit risk in relation to its financial assets. The directors of the Company are of the opinion that the Group was not exposed to any significant concentration of credit risk as of December 31, 2021 and 2020.

(c)      Liquidity risk

Cash flow forecast is performed in the operating entities of the Group and aggregated by the Group Treasury. The Group Treasury monitors rolling forecasts of the Group’s liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities at all times so that the Group does not breach borrowing limits or covenants (where applicable) on any of its borrowing facilities. This forecast takes into consideration of the Group’s debt financing plans, covenant compliance, compliance with internal balance sheet ratio targets and, if applicable, external regulatory or legal requirements, for example, currency restrictions.

Management also monitors rolling forecasts of the Group’s liquidity reserve on the basis of expected cash flows.

As of December 31, 2021, the Group’s current liabilities exceeded its current assets by approximately RMB3,467 million (December 31, 2020 (restated): RMB16,364 million), please refer to Note 2.1.2 for the assessment made by the Company.

The table below analyses the maturity profile of the Group’s financial liabilities as of the end of the reporting period. The amounts disclosed in the table are the contractual undiscounted cash flows.

(b) Fair value and fair value hierarchy

Fair value

The carrying amounts and fair values of the Group’s financial instruments at amortized cost, other than those with carrying amounts that reasonably approximate to fair values and those carried at fair value, are as follows:

	Carrying amounts		Fair values
	December 31,	December 31,	December 31,	December 31,
	2020	2021	2020	2021
Financial liabilities
Financial liabilities included in other non-current liabilities (Note 21)	880,864	1,036,917	767,922	903,141
Long-term interest-bearing loans and borrowings, excluding lease liability (Note 19)	52,489,058	51,260,218	49,233,629	49,729,548
	53,369,922	52,297,135	50,001,551	50,632,689

Except for financial assets and financial liabilities mentioned above, management has assessed that the fair values of cash and cash equivalents, restricted cash and time deposits, trade and notes receivables, financial assets included in other current assets, entrusted loans, trade and notes payables, financial liabilities included in other payables and accrued liabilities, short-term and the current portion of interest-bearing loans and borrowings, interest payable and the current portion of long-term payables approximate to their carrying amounts largely due to the short term maturities of these instruments.

The fair values of the financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

The fair values of the financial assets included in other non-current assets and financial liabilities included in other non-current liabilities and long-term interest bearing loans and borrowings have been calculated by discounting the expected future cash flows using rates currently available for instruments on with similar terms, credit risk and remaining maturities.

The Group’s own non-performance risk for financial liabilities included in other non-current liabilities and long-term interest-bearing loans and borrowings as of December 31, 2021 and 2020 were assessed to be insignificant.

37.3   Capital risk management

The Group’s capital management objectives are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders, and to maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, issue new shares or sell assets to reduce debts.

Consistent with other entities in the industry, the Group monitors capital on the basis of its gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total liabilities (excluding deferred tax liabilities, income tax payable and deferred government grants) less restricted cash, time deposits and cash and cash equivalents. Total capital is calculated as equity, as shown in the consolidated statement of financial position, plus net debt less non-controlling interests.

The gearing ratio as of December 31, 2020 and 2021 are as follows:

	December 31,		December 31,
	2020		2021
	(Restated)
