3.D. Risk Factors

Our operations are subject to certain risk factors that may affect SQM’s business, financial condition, cash flows, or results of operations. In addition to other information contained in this Annual Report on Form 20-F, you should carefully consider the risks described below. These risks are not the only ones we face. Additional risks not currently known to us or that are known but that we currently believe are not significant may also affect our business operations. Our business, financial condition, cash flows or results of operations could be materially affected by any of these risks.

Risks Relating to our Business

Our inability to extend or renew the mineral exploitation rights relating to the Salar de Atacama concession, upon which our business is substantially dependent, beyond their current expiration date in December 2030 could have a material adverse effect on our business, financial condition and results of operations.

Our subsidiary SQM Salar S.A. (“SQM Salar”), as leaseholder, holds exclusive and temporary rights to exploit mineral resources in the Salar de Atacama in northern Chile. These rights are owned by Corfo, a Chilean government entity, and leased to SQM Salar pursuant to (i) a 1993 lease agreement over mining exploitation concessions between SQM Salar and Corfo, as amended from time to time (the “Lease Agreement”), and (ii) the Salar de Atacama project agreement between Corfo and SQM Salar, as amended from time to time (the “Project Agreement”). The Lease Agreement provides for SQM Salar to (i) make quarterly lease payments to Corfo based on product sales from leased mining properties and annual contributions to research and development, to local communities, to the Antofagasta Regional Government and to the municipalities of San Pedro de Atacama, María Elena and Antofagasta, (ii) maintain Corfo’s rights over the mining exploitation concessions and (iii) make annual payments to the Chilean government for such concession rights. The Lease Agreement expires on December 31, 2030.

Our business is substantially dependent on the exploitation rights under the Lease Agreement and the Project Agreement, since all of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. For the year ended December 31, 2021, revenues related to products originating from the Salar de Atacama represented 47% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. As of December 31, 2021, only 9 years remain on the term of the Lease Agreement and we had extracted approximately 32% of the total permitted accumulated extraction and sales limit of lithium under the lithium extraction and sales limits.

1

Although we expect to begin the process of discussing the extension or renewal of the mineral exploitation rights in the Salar de Atacama under the Lease Agreement and Project Agreement with Corfo well in advance of the December 2030 expiration date, we cannot assure you that we will successfully reach an agreement with Corfo to extend or renew our mineral exploitation rights beyond 2030. Any negotiation with Corfo for an extension or renewal could involve renegotiation of any or all of the terms and conditions of the Lease Agreement and Project Agreement, including, among other things, the lithium and potassium extraction and sales limits, the lease payment rates and calculations, or other payments to Corfo.

In the event that we are not able to extend or renew the Lease Agreement beyond the current expiration date of the Lease Agreement in 2030, we would be unable to continue extraction of lithium and potassium under the Lease Agreement, which could have a material adverse effect on our business, financial condition and results of operations.

Volatility of world lithium, fertilizer and other chemical prices and changes in production capacities could affect our business, financial condition and results of operations.

The prices of our products are determined principally by world prices, which, in some cases, have been subject to substantial volatility in recent years. World lithium, fertilizer and other chemical prices constantly vary depending upon the relationship between supply and demand at any given time. Supply and demand dynamics for our products are tied to a certain extent to global economic cycles and have been impacted by circumstances related to such cycles. Furthermore, the supply of lithium, certain fertilizers, or other chemical products, including certain products that we provide, varies principally depending on the production of the major producers, (including us) and their respective business strategies.

We expect that prices for the products we manufacture will continue to be influenced, among other things, by worldwide supply and demand and the business strategies of major producers. Some of the major producers (including us) have increased or decreased production and have the ability to increase or decrease production.

As a result of the above, the prices of our products may be subject to substantial volatility. High volatility or a substantial decline in the prices or sales volumes of one or more of our products could have a material adverse effect on our business, financial condition and results of operations.

Our sales could be impacted by global shipping constraints

We sell our products in more than 110 countries in the world. Our products are shipped

in containers or break bulk format

from the port terminals in Antofagasta, Tocopilla, Mejillones and Iquique in Chile.

Current challenges in the global shipping industry have led to congestion in ports, a shortage in containers, and a lack of space on ships. Because of this situation, we face a risk of potential supply chain disruptions that may adversely affect our operations and ability to deliver our products to our customers.

Depending on the terms of shipments to customers, the risk of loss

related to these shipping issues

could fall on us.

Additionally, our revenues and collections may also be adversely affected by significant increases in the cost of transportation, as a result of increases in fuel or labor costs, higher demand for

logistics

services, or otherwise, and transportation delays that

could have a

negative impact

on our

sales agreements

and

customer relationships

.

2

Our sales to emerging markets and expansion strategy expose us to risks related to economic conditions and trends in those countries.

We sell our products in more than 110 countries around the world. In 2021, approximately 53% of our sales were made in emerging market countries: 11% in Latin America (excluding Chile); 8% in Africa and the Middle East (excluding Israel); 8% in Chile

;

and 26% in Asia and Oceania (excluding Australia, Japan, New Zealand, South Korea and Singapore). In Note 21.1 to our consolidated financial statements, we reported revenues from Chile

,

Latin America and the Caribbean and Asia and others of US$1.8 billion. We expect to expand our sales in these and other emerging markets in the future. In addition, we may carry out acquisitions or joint ventures in jurisdictions in which we currently do not operate, relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages. The results of our operations and our prospects in other countries in which we establish operations will depend, in part, on the general level of political stability, economic activity and policies in those countries as well as the duration of the COVID-19 or other pandemics. Future developments in the political systems or economies of these countries or the implementation of future governmental policies in those countries, including the imposition of withholding and other taxes, restrictions on the payment of dividends or repatriation of capital, the imposition of import duties or other restrictions, the imposition of new environmental regulations or price controls or changes in relevant laws or regulations, could have a material adverse effect on our business, financial condition and results of operations in those countries.

Our inventory levels may vary for economic or operational reasons.

In general, economic conditions or operational factors can affect our inventory levels. Higher inventories carry a financial risk due to increased need for cash to fund working capital and could imply an increased risk of loss of product. At the same time, lower levels of inventory can hinder the distribution network and process, thus impacting sales volumes. There can be no assurance that inventory levels will remain stable. These factors could have a material adverse effect on our business, financial condition and results of operations.

New production of iodine, potassium nitrate or lithium from current or new competitors in the markets in which we operate could adversely affect prices.

In recent years, new and existing competitors have increased the supply of iodine, potassium nitrate and lithium, which has affected prices for those products. Further production increases could negatively impact prices. There is limited information on the status of new iodine, potassium nitrate or lithium production capacity expansion projects being developed by current and potential competitors and, as such, we cannot make accurate projections regarding the capacities of possible new entrants into the market and the dates on which they could become operational. If these potential projects are completed in the short term, they could adversely affect market prices and our market share, which, in turn, could have a material adverse effect on our business, financial condition and results of operations.

We have a capital expenditure program that is subject to significant risks and uncertainties.

Our business is capital intensive. Specifically, the exploration and exploitation of reserves, mining and processing costs, the maintenance of machinery and equipment and compliance with applicable laws and regulations require substantial capital expenditures. We must continue to invest capital to maintain or to increase our exploitation levels and the amount of finished products we produce. For example, we have a US$2.25 billion investment plan for the years 2021-2024. The plan will allow us to expand our operations of lithium, iodine and nitrate by accessing natural resources both in the Salar de Atacama and caliche ore deposits in Chile as well as through the 50,0000 metric ton Mt. Holland lithium hydroxide project in Western Australia (a joint venture that we are developing with our partner Wesfarmers). The plan also aims to increase our mining capacity while protecting the environment, reduce operational costs and increase our annual production capacity of nitrates and iodine to meet expected growth in those markets.

Mining industry development projects typically require a number of years and significant expenditures before production can begin. Such projects could experience unexpected problems and delays during development, construction and start-up.

Our decision to develop a project typically is based on the results of feasibility studies, which estimate the anticipated economic returns of a project. The actual project profitability or economic feasibility may differ from such estimates as a result of any of the following factors, among others: changes in tonnage, grades and metallurgical characteristics of ore or other raw materials to be mined and processed; estimated future prices of the relevant products; changes in customer demand; higher construction and infrastructure costs; the quality of the data on which engineering assumptions were made; higher production costs; adverse geotechnical conditions; availability of adequate labor force; availability and cost of water and energy; availability and cost of transportation; fluctuations in inflation and currency exchange rates; availability and terms of financing; and potential delays relating to social and community issues.

In addition, we require environmental permits for our new projects. Obtaining permits in certain cases may cause significant delays in the execution and implementation of new projects and, consequently, may require us to reassess the related risks and economic incentives.

This may require modifying our operations to incorporate the use of seawater and updating our mining equipment and operational centers.

We cannot assure you that we will be able to maintain our production levels or generate sufficient cash flow or that we will have access to sufficient investments, loans or other financing alternatives, to continue our activities at or above present levels, or that we will be able to implement our projects or receive the necessary permits required for them in time. Any or all of these factors may have a material adverse effect on our business, financial condition and results of operations.

High raw materials and energy prices could increase our production costs and cost of sales, and energy may become unavailable at any price.

We rely on certain raw materials and various energy sources (diesel, electricity, liquefied natural gas, fuel oil and others) to manufacture our products. Purchases of energy and raw materials we do not produce constitute an important part of our cost of sales, approximately 15% in 2021. In addition, we may not be able to obtain energy at any price if supplies are curtailed or otherwise become unavailable. To the extent we are unable to pass on increases in the prices of energy and raw materials to our customers or we are unable to obtain energy, our business, financial condition and results of operations could be materially adversely affected.

Our reserve estimates are internally prepared and not subject to review by external geologists or an external auditing firm and could be subject to significant changes, which may have a material adverse effect on our business, financial condition and results of operations.

Our caliche ore mining reserve estimates and our Salar de Atacama brine mining reserve estimates are prepared by our own geologists and hydrogeologists and are not subject to authentication by external geologists or an external auditing firm. However, our reserve estimates in the Salar de Atacama were reviewed by qualified persons and this information is presented to Corfo.

Previously

, our reserve estimates in the Salar de Atacama were also reviewed by the Superior Council for Scientific Investigations (

Consejo Superior de Investigaciones Científicas

) or CSIC, and this information was presented to CCHEN.

Estimation methods involve numerous uncertainties as to the quantity and quality of the reserves, and reserve estimates could change upwards or downwards.

A downward change in our estimates and/or quality of our reserves could affect future volumes and costs of production and therefore have a material adverse effect on our business, financial condition and results of operations.

4

Chemical and physical properties of our products could adversely affect their commercialization.

Since our products are derived from natural resources, they contain inorganic impurities that may not meet certain customer or government standards. As a result, we may not be able to sell our products if we cannot meet such requirements. In addition, our cost of production may increase in order to meet such standards. Failure to meet such standards could materially adversely affect our business, financial condition and results of operations if we are unable to sell our products in one or more markets or to important customers in such markets.

Changes in technology or other developments could result in preferences for substitute products.

Our products, particularly iodine, lithium and their derivatives, are preferred raw materials for certain industrial applications, such as rechargeable batteries and liquid-crystal displays (LCDs). Changes in technology, the development of substitute products or other developments could adversely affect demand for these and other products which we produce. In addition, other alternatives to our products may become more economically attractive as global commodity prices shift. Any of these events could have a material adverse effect on our business, financial condition and results of operations.

We are exposed to labor strikes and labor liabilities that could impact our production levels and costs.

Over 93% of our employees are employed in Chile, of which approximately 66% were represented by 20 labor unions as of December 31, 2021. As of December 31, 2021, all collective bargaining agreements had been renegotiated. We are exposed to labor strikes and illegal work stoppages by both our own employees and our independent contractors’ employees that could impact our production levels in both our own plants and our independent contractors’ plants. If a strike or illegal work stoppage occurs and continues for a sustained period of time, we could be faced with increased costs and even disruption in our product flow that could have a material adverse effect on our business, financial condition and results of operations.

We are and might be subject to new and upcoming labor laws and regulations in Chile and may be exposed to liabilities and potential costs for non-compliance.

We are subject to recently enacted and might be subject to new local labor laws and regulations that govern, among other things, the relationship between us and our employees and will be subject to new labor bills currently under discussion in the Chilean Congress, mainly as a result of the impact of the global novel coronavirus (COVID-19) pandemic as well as to the economic and political volatility and civil unrest in Chile beginning in October and November 2019. There have been changes and proposed changes to various labor laws which include, but are not limited to, modifications related to teleworking, inclusion of workers with disabilities, minimum wage, unemployment insurance benefits, employee and employer relationships, pensions, profit sharing, regular work hours and other matters related to COVID-19.

Any changes to regulations to which we are subject could have a material adverse effect on our business, financial condition and results of operations.

Lawsuits and arbitrations could adversely impact us.

We are party to a range of lawsuits and arbitrations involving different matters as described in Note

20

to our Consolidated Financial Statements and “Item 8.A. Legal Proceedings.” Although we intend to defend our positions vigorously, our defense of these actions may not be successful

and responding to such lawsuits and arbitrations diverts our management’s attention from day-to-day operations. Adverse judgments or settlements in these lawsuits may have a material adverse effect on our business, financial condition and results of operations. In addition, our strategy of being a world leader includes entering into commercial and production alliances, joint ventures and acquisitions to improve our global competitive position. As these operations increase in complexity and are carried out in different jurisdictions, we may be subject to legal proceedings that, if settled against us, could have a material adverse effect on our business, financial condition and results of operations.

5

We have operations in multiple jurisdictions with differing regulatory, tax and other regimes.

We operate in multiple jurisdictions with complex regulatory environments that are subject to different interpretations by companies and respective governmental authorities. These jurisdictions may have different tax codes, environmental regulations, labor codes and legal framework, which adds complexity to our compliance with these regulations.  Any failure to comply with such regulations could have a material adverse effect on our business, financial condition and results of operations.

Environmental laws and regulations could expose us to higher costs, liabilities, claims and failure to meet current and future production targets.

Our operations in Chile are subject to national and local regulations relating to environmental protection. In accordance with such regulations, we are required to conduct environmental impact studies or statements before we conduct any new projects or activities or significant modifications of existing projects that could impact the environment or the health of people in the surrounding areas.  We are also required to obtain an environmental license for those projects and activities. The Chilean Environmental Assessment Service (

Servicio de Evaluación Ambiental

) evaluates environmental impact studies and statements submitted for its approval. The public, government agencies or local authorities may review and challenge projects that may adversely affect the environment, either before these projects are executed or once they are operating, if they fail to comply with applicable regulations. In order to ensure compliance with environmental regulations, Chilean authorities may impose fines up to approximately US$9 million per infraction, revoke environmental permits or temporarily or permanently close facilities, among other enforcement measures.

Chilean environmental regulations have become increasingly stringent in recent years, both with respect to the approval of new projects and in connection with the implementation and development of projects already approved, and we believe that this trend is likely to continue. Given public interest in environmental enforcement matters, these regulations or their application may also be subject to political considerations that are beyond our control.

We regularly monitor the impact of our operations on the environment and on the health of people in the surrounding areas and have, from time to time, made modifications to our facilities to minimize any adverse impact. Future developments in the creation or implementation of environmental requirements or their interpretation could result in substantially increased capital, operation or compliance costs or otherwise adversely affect our business, financial condition and results of operations.

The success of our current investments at the Salar de Atacama and Nueva Victoria is dependent on the behavior of the ecosystem variables being monitored over time. If the behavior of these variables in future years does not meet environmental requirements, our operation may be subject to important restrictions by the authorities on the maximum allowable amounts of brine and/or water extraction. For example, on December 13, 2017, the Environmental Court of Antofagasta ordered a temporary and partial closure of certain water extraction wells located in the Salar de Llamara. In October 2018, the Environmental Court of Antofagasta accepted our claim, and dismissed the restrictions without prejudice. It is possible that third parties could seek to reinstate these restrictions in the future. On December 26, 2019, the same Court ruled that the environmental compliance plan presented by SQM Salar S.A. with respect to the Salar de Atacama and approved by the Chilean Environmental Enforcement Authority (

Superintendencia del Medio Ambiente

) or SMA in January 2019, did not comply with certain completeness and efficiency requirements of the Chilean environmental legislation.

6

In September 2021, SQM Salar S.A. proposed to the SMA a new environmental compliance plan, which is currently subject to review. We believe that the new proposed environmental compliance plan, safeguards the protection of the environment and is evaluating all courses of action available under applicable law with respect to this ruling.

Our future development depends on our ability to sustain future production levels, which requires additional investments and the submission of the corresponding environmental impact studies or statements. If we fail to obtain approval or required environmental licenses, our ability to maintain production at specified levels will be seriously impaired, thus having a material adverse effect on our business, financial condition and results of operations.

In addition, our worldwide operations are subject to international and local environmental regulations. Since environmental laws and regulations in the different jurisdictions in which we operate may change, we cannot guarantee that future environmental laws, or changes to existing environmental laws, will not materially adversely impact our business, financial condition and results of operations.

A significant percentage of our shares are held by two principal shareholder groups who may have interests that are different from that of other shareholders and of each other. Any change in such principal shareholder groups may result in a change of control of the Company or of its Board of Directors or its management, which may have a material adverse effect on our business, financial condition and results of operations.

As of March 1, 2022, two principal shareholder groups held in the aggregate 48.33% of our total outstanding shares, including 94.19% of our Series A common shares, and have the power to elect six of our eight directors. The interests of the two principal shareholder groups may in some cases differ from those of other shareholders and of each other.

As of March 1, 2021, one principal shareholder group is Sociedad de Inversiones Pampa Calichera S.A. and its related companies, Inversiones Global Mining Chile Limitada and Potasios de Chile S.A. (together, the “Pampa Group”), which owned approximately 25.20% of the total outstanding shares of SQM, and another principal shareholder is Tianqi Lithium Corporation (“Tianqi”), which directly and indirectly owned approximately 23.13% of the total outstanding shares of SQM.

The divestiture by the Pampa Group or Tianqi, or potential changes in the circumstances that have led to the determination of the CMF that there is currently no controlling shareholder of the Company, or a combination thereof, may have a material adverse effect on our business, financial condition and results of operations.

Tianqi is a significant shareholder and a competitor of the Company, which could result in risks to free competition

Tianqi is a competitor in the lithium business, and as a result of the number of SQM shares that it owns, it has the right to choose up to three Board members. Under Chilean law, we are restricted in our ability to decline to provide information about us, which may include competitively sensitive information, to a director of our company. On August 27, 2018, Tianqi and the Chilean antitrust regulator, the Chilean National Economic Prosecutor’s Office (

Fiscalía Nacional Económica

), or FNE, entered into an extrajudicial agreement, under which certain restrictive measures were implemented in order to (i) maintain the competitive conditions of the lithium market, (ii) mitigate the risks described in the agreement and (iii) limit Tianqi’s access to certain information of the Company and its subsidiaries, which is defined as “sensitive information” under the agreement.

During the approval process of the extrajudicial agreement before the FNE, we expressed our concerns regarding the measures contained in the extrajudicial agreement since, in the Company’s opinion, the measures (i)  could not effectively resolve the risks that Tianqi and the FNE have sought to mitigate, (ii) are not sufficient to avoid access to our “sensitive information” that, in the possession of a competitor, could harm us and the proper functioning of the market and (iii) could contradict the Chilean Corporations Act.

7

The presence of a shareholder which is at the same time a competitor of ours and the right of this competitor to choose Board members could generate risks to free competition and/or increase the risks of an investigation of free competition against us, whether in Chile or in other countries, all of which could have a material adverse effect on our business, financial condition and results of operations.

Our information technology systems may be vulnerable to disruption which could place our systems at risk from data loss, operational failure, or compromise of confidential information.

We rely on various computer and information technology systems, and on third party developers and contractors, in connection with our operations, including two networks that link our principal subsidiaries to our operating and administrative facilities in Chile and other parts of the world and ERP software systems, which are used mainly for accounting, monitoring of supplies and inventories, billing, quality control, research activities, and production process and maintenance control.  In addition, we use cloud technologies, which allows us to support new business processes and respond quickly and at low cost to changing conditions in our business and of the markets. Our information technology systems are susceptible to disruption, damage or failure from a variety of sources, including errors by employees or contractors, computer viruses, cyber-attacks, misappropriation of data by outside parties, and various other threats. We have taken measures to identify and mitigate these risks with the object of reducing operational risk and improving security and operational efficiency, which also includes modernization of existing information technology infrastructure and communications systems. However, we cannot guarantee that due to the increasing sophistication of cyber-attacks our systems will not be compromised and because we do not maintain specialized cybersecurity insurance, our insurance coverage for protection against cybersecurity risk may not be sufficient. Cybersecurity breaches could result in losses of assets or production, operational delays, equipment failure, inaccurate recordkeeping, or disclosure of confidential information, any of which could result in business interruption, reputational damage, lost revenue, litigation, penalties or additional expenses and could have a material adverse effect on our business, financial condition and results of operations.

Recent international trade tensions could have a negative effect on our financial performance.

Economic conditions in China, an important market for the Company, are sensitive to global economic conditions. The global financial markets have experienced significant disruptions in the past, including the recent international trade disputes and tariff actions announced by the United States, China and certain other countries. The U.S. government has imposed significant tariffs on Chinese goods, and Chinese government has, in turn, imposed tariffs on certain goods manufactured in the United States. There is no assurance that the list of goods impacted by additional tariffs will not be expanded or the tariffs will not be increased materially. We are unable to predict how China or U.S. government policy, in particular, the outbreak of a trade war between China and the United States and additional tariffs on bilateral imports, may continue to impact global economic conditions. If the list of goods is further expanded or the tariff is further increased, global economic conditions of both countries could be impacted, and growth in demand for lithium or other commodities could decrease, which may have a material adverse effect on our business, financial condition and results of operations.

Outbreaks of communicable infections or diseases, or other public health pandemics, such as the outbreak of the novel coronavirus (COVID-19) currently being experienced around the world, have impacted and may further impact the markets in which we, our customers and our suppliers operate or market and sell products and could have a material adverse effect on our operations business, financial condition and results of operations.

Disease outbreaks and other public health conditions, such as the global outbreak of COVID-19 currently being experienced, in markets in which we, our customers and our suppliers operate, could have a significant negative impact on our revenues, profitability and business. The Chilean government has imposed several measures that may affect our operations, including mandatory quarantines for people who have been in contact with infected people, restrictions on the number of people that can be together, and lockdowns on specific communities that may suffer higher rates of infection or death, among others.

As a precaution, our management has voluntarily implemented several additional measures to help reduce the speed at which COVID-19 may spread in our company, including measures to mitigate the spread in the workplace, significant reductions in employee travel and a mandatory quarantine for people who have arrived from high-risk destinations, in consultation with governmental and international health organization guidelines, and will continue to implement measures consistent with the evolving COVID-19 situation. While these measures have been implemented to reduce the risk of the spread of the virus in our facilities, there can be no assurance that these measures will reduce or limit the impact of COVID-19 on our operations, business, financial condition or results of operations. Our operations could be stopped as a result of, among other reasons, regulatory restrictions or a significant outbreak of the virus among our staff, which could prevent employees from reporting to shifts.

While the global impacts of the COVID-19 pandemic are constantly changing, international financial markets have reflected the uncertainty associated with the slowdown of the global economy and the potential impact if businesses, workers, customers and others are prevented or restricted from conducting business activities due to quarantines, business closures or other restrictions imposed by businesses or governmental authorities in response to the COVID-19 outbreak.

If our stakeholders and other constituencies believe we fail to appropriately address sustainability and other environmental, social and governance (ESG) concerns it may adversely affect our business.

In October 2020, we announced our sustainable development plan, which includes voluntarily expanding our monitoring systems, promoting better and more profound conversations with neighboring communities and becoming carbon neutral and reducing water by 65% and brine extraction by 50% of our authorized limits. We also announced a goal of obtaining international certifications and participating in international sustainability indices which we consider essential for a sustainable future.

While we are dedicated to our efforts related to sustainability, if we fail to address appropriately all relevant stakeholders’ concerns in connection with ESG criteria, we may face opposition, which could negatively affect our reputation, delay operations, or lead to litigation threats or actions. If we do not maintain our reputation with key stakeholders and constituencies and effectively manage these sensitive issues, they could adversely affect our business, results of operations, and financial condition.

Climate change and a global transition to a low carbon economy can create physical risks and other risks that could adversely affect our business and operations and adverse weather conditions or significant changes in weather patterns could have a material adverse impact on our results of operations.

The impact of climate change and climate change-driven responses, such as a global transition to a low carbon economy on our operations and our customers’ operations

,

remains uncertain, but  the regulatory, market-risks associated with climate change as well as the physical effects of climate change could have an adverse effect on us and our customers as experts believe that climate change may be associated with more extreme weather conditions These effects could include, but may not be limited to, changes in regional weather patterns, including drought and rainfall levels, water availability, sea levels, storm patterns and intensities and temperature levels, including increased volatility in seasonal temperatures via excessively hot or cold temperatures. These extreme weather conditions could vary by geographic location.

9

Climate-derived threats include, among others, changes in regional weather patterns, including changes in precipitation and evaporation parameters that, on the one hand, intensify drought phenomena, affecting the availability of water and, on the other hand, bring intense rains in short periods of time that generate other unwanted events that affect our operation and also our surrounding communities, such as road closures, infrastructure, landslides, among others. Additionally, rising sea levels and storm surges, increasing the days of port closures could impact the supply chain affecting our customers and suppliers. Other events such as storm patterns and intensities, increased wind speed, heat waves, cold waves, among other events considered as acute physical risks of climate change. Other effects are related to temperature levels, including increased volatility in seasonal temperatures through excessively high or low temperatures. These extreme weather conditions may vary by geography and location. Weather conditions have historically caused volatility in the agricultural industry (and indirectly in our results of operations) by causing crop failures or significantly reduced harvests, which can adversely affect application rates, demand for our plant nutrition products and our customers’ creditworthiness. Weather conditions can also lead to a reduction in farmable acres, flooding, drought or wildfires, which could also adversely impact growers’ crop yields and the uptake of plant nutrients, reducing the need for application of plant nutrition products for the next planting season which could result in lower demand for our plant nutrition products and negatively impact the prices of our products.

Any prolonged change in weather patterns in our markets, as a result of climate change or otherwise, could have a material adverse impact on the results of our operations.

Risks Relating to Financial Markets

Currency fluctuations may have a negative effect on our financial performance.

We transact a significant portion of our business in U.S. dollars, and the U.S. dollar is the currency of the primary economic environment in which we operate. In addition, the U.S. dollar is our functional currency for financial statement reporting purposes. A significant portion of our costs, however, is related to the Chilean peso. Therefore, an increase or decrease in the exchange rate between the Chilean peso and the U.S. dollar would affect our costs of production. The Chilean peso has been subject to large devaluations and revaluations in the past and may be subject to significant fluctuations in the future. As of December 31, 2021, the Chilean peso exchange rate was Ch$844.69 per U.S. dollar, while as of December 31, 2020 the Chilean peso exchange rate was Ch$710.95 per U.S. dollar. The Chilean peso therefore depreciated against the U.S. dollar by 18.8% in 2021. As of March 1, 2022, the Observed Exchange Rate was Ch$798.01 per U.S. dollar.

As an international company operating in several other countries, we also transact business and have assets and liabilities in other non-U.S. dollar currencies, such as, among others, the Euro, the South African rand, the Mexican peso, the Chinese yuan, the Thai baht and the Brazilian real.

As a result, fluctuations in the exchange rates of such foreign currencies to the U.S. dollar may have a material adverse effect on our business, financial condition and results of operations.

10

We may be subject to risks associated with the discontinuation, reform or replacement of benchmark indices.

Interest rate, foreign exchange rate and other types of indices which are deemed to be “benchmarks” are the subject of increased regulatory scrutiny and may be discontinued, reformed or replaced. For example, in 2017, the U.K. Financial Conduct Authority announced that it will no longer persuade or compel banks to submit rates for the calculation of the London interbank offered rate (“LIBOR”) benchmark after 2021. This reform will, and other future reforms may, cause benchmarks to be different than they have been in the past, or to disappear entirely, or have other consequences which cannot be fully anticipated which introduces a number of risks for our business. These risks include (i) legal risks arising from potential changes required to document new and existing transactions; (ii) financial risks arising from any changes in the valuation of financial instruments linked to benchmark rates; (iii) pricing risks arising from how changes to benchmark indices could impact pricing mechanisms on some instruments; (iv) operational risks arising from the potential requirement to adapt IT systems, trade reporting infrastructure and operational processes; and (v) conduct risks arising from the potential impact of communication with customers and engagement during the transition period. Various replacement benchmarks, and the timing of and mechanisms for implementation are being considered. The transition away from LIBOR to risk-free reference rates (RFRs) requires financial firms to make a variety of internal changes, for example updating front-and back-office systems, retraining staff and redesigning processes, as well as potentially modifying or renegotiating potentially thousands of LIBOR-linked contracts. All banks and other financial market participants must eliminate their dependence on LIBOR by this date if they are to avoid disruption when the publication of LIBOR ceases. Although as of December 31, 2021 we had approximately US$70 million short- and long-term debt that use a LIBOR benchmark, it is not currently possible to determine whether, or to what extent, any such changes would affect us. However, the discontinuation or reformation of existing benchmark rates or the implementation of alternative benchmark rates may have a material adverse effect on our business, financial condition and results of operations. 

In addition to the financial benchmarks, there are also market benchmarks used for the pricing of our long-term supply contracts, which may also be subject to regulatory scrutiny, or which may be discontinued, reformed or replaced. For example, for some of our long-term supply contracts, prices reference to indices prepared by commodity reporting agencies such as the Shanghai Metals Market (SMM) and Fastmarkets.

Risks Relating to Chile

As we are a company based in Chile, we are exposed to political risks and civil unrest in Chile.

Our business, financial condition and results of operations could be affected by changes in policies of the Chilean government, other political developments in or affecting Chile, legal changes in the standards or administrative practices of Chilean authorities or the interpretation of such standards and practices, over which we have no control.  The Chilean government has modified, and has the ability to modify, monetary, fiscal, tax, social and other policies in order to influence the Chilean economy or social conditions.  We have no control over government policies and cannot predict how those policies or government intervention will affect the Chilean economy or social conditions, or, directly and indirectly, our business, financial condition and results of operations. Changes in policies involving exploitation of natural resources, taxation and other matters related to our industry may adversely affect our business, financial condition and results of operations.

We are exposed to economic and political volatility and civil unrest in Chile.  Changes in social, political, regulatory and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment in Chile, as well as crises and political uncertainties in Chile, could adversely affect economic growth in Chile.  In October and November 2019, Chile experienced riots and widespread mass demonstrations in Santiago and other major cities in Chile, triggered by an increase in public transportation fares in the city of Santiago, which involved violence and significant property damage and caused commercial disruptions throughout the country. As a result, on October 18, 2019 the Chilean government declared a 15-day period state of emergency and imposed a nighttime curfew in the greater Santiago region and other cities. The state of emergency has since been lifted and the Chilean government has introduced several social reforms. Also in 2019, then President Sebastian Piñera announced a pay cut for members of the Chilean Congress and the highest-paid civil servants and replaced eight ministers of his government. On November 15, 2019, representatives of Chile’s leading political parties agreed to hold a referendum, allowing Chileans to vote on whether to replace the Chilean Constitution. In a November 2020 referendum, Chilean citizens strongly supported convening a constitutional convention to draft a new Chilean Constitution. Any new Constitution could significantly alter the Chilean political situation, affect the Chilean economy, its business outlook, change existing rights, including rights to exploit natural resources, and water and property rights, any of which could adversely affect our business, results of operations, and financial condition.

The constitutional convention has already drafted proposals that may have a material impact on our business and operations. Although the final text of the Constitution is still being discussed and the voting of the proposals is still at an initial stage, the convention has accepted some proposals which seek to annul all of the existing mining and water rights and establish a whole new regime regarding mining and exploitation of natural resources. Also, the convention has approved certain proposals seeking to protect indigenous people and to recover indigenous land and territories. Part of our operations are located in areas that may be deemed to be indigenous land according to current and future legislation. Once the full text of the new Chilean Constitution has been drafted, it will be submitted to a national referendum in which the Chilean citizens will decide to approve or reject this text by a simple majority vote. We cannot predict the outcome of such referendum. If the referendum rejects the text of the new Chilean Constitution, the existing Chilean Constitution would remain in effect.

We cannot give any assurance that these reforms and proposals or the constitutional reform process will resolve the social and economic concerns or that mass protests or civil unrest will not resume. The long-term effects of this social unrest are hard to predict but could include slower economic growth, which could adversely affect our business, results of operations, and financial condition.

12

In addition, in December 2021, Chile elected Gabriel Boric as the new president. President Boric took office on March 11, 2022 and his agenda is mainly focused on the elimination of private pension funds, social security programs, increases in the minimum wage and pensions, and increases in corporate taxes. President Boric is also a strong supporter of the constitutional reforms being considered by the constitutional convention drafting a new Chilean Constitution. While it is still very early in President Boric’s term and there is uncertainty regarding how President Boric’s reforms may affect the political and business climate in Chile in the future, it is possible that these reforms could lead to higher-than-expected inflation levels, unemployment, higher corporate taxes and financial constraints on small and medium-sized companies, any of which could have an adverse effect on our business, results of operations, and financial condition.

Future adverse developments in Chile, including political events, financial or other crises, changes to policies regarding foreign exchange controls, regulations, and taxation, may impair our ability to execute our business plan and could adversely affect our growth, results of operations, and financial condition. Inflation, devaluation, social instability, and other political, economic, or diplomatic developments could also reduce our profitability. Economic and market conditions in Chilean financial and capital markets may be affected by international events, which could unfavorably affect the value of our securities.

Changes to the Chilean Constitution could impact a wide range of rights, including mining rights, water rights and property rights generally, and could affect our business, financial condition and results of operations.

A new Chilean Constitution is in the process of being drafted by a constitutional convention, which was convened on July 4, 2021. The constitutional convention will have approximately one year to draft an entirely new Chilean Constitution. A wide range of rights could potentially be under consideration for reform under the new Chilean Constitution, including mining rights, water rights and property rights generally. If approved by the constitutional convention, the final draft of the new Chilean Constitution will be submitted for approval to a public referendum with mandatory participation and would require a simple majority vote for approval. If a new Constitution is not approved, the existing Chilean Constitution, which has been in place since 1980, would remain in effect. There can be no assurance that the constitutional convention will agree on a draft of a new Chilean Constitution or that the Chilean citizens will approve any draft Chilean Constitution approved by the constitutional convention. Any changes to rights under a new Chilean Constitution could change the political situation of Chile and affect the Chilean economy and the business outlook for the country generally and our business, results of operations, and financial condition.

Changes in regulations regarding, or any revocation or suspension of mining, port or other concessions could affect our business, financial condition and results of operations.

We conduct our mining operations, including brine extraction, under exploitation and exploration concessions granted in accordance with provisions of the Chilean Constitution and related laws and statutes. Our exploitation concessions essentially grant a perpetual right (with the exception of the rights granted to SQM Salar with respect to the Salar de Atacama concessions under the Lease Agreement described above, which expires in 2030) to conduct mining operations in the areas covered by the concessions, provided that we pay annual concession fees. Our exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time and to subsequently request a corresponding exploitation concession. Any changes to the Chilean Constitution with respect to the exploitation and exploration of natural resources and concessions granted as a result of the constitutional convention could materially adversely affect our existing exploitation and exploration concessions or our ability to obtain future concessions and could have a material adverse effect on our business, financial condition and results of operations.

We also operate port facilities at Tocopilla, Chile, for the shipment of products and the delivery of raw materials pursuant to maritime concessions, which have been granted under applicable Chilean laws and are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

Any significant adverse changes to any of these concessions, any changes to regulations to which we are subject or adverse changes to our other concession rights, or a revocation or suspension of any of our concessions, could have a material adverse effect on our business, financial condition and results of operations.

Changes in water rights laws and other regulations could affect our business, financial condition and results of operations.

We hold water use rights that are key to our operations. These rights were obtained from the Chilean Water Authority (

Dirección General de Aguas

) for supply of water from rivers and wells near our production facilities, which we believe are sufficient to meet current operating requirements.

In January 2022, the Chilean Congress approved a bill that amends the

Chilean

Water Code

(

Código de Agua

),

which is only waiting for its promulgation and subsequent publication in order to

become

an applicable Chilean law. This modification introduces several changes to the

Water Code.

  A

significant

amendment is the change in the

time periods for

which the water rights were granted. According to this new legislation

,

water rights

: (1)

will have a temporary nature being granted for a maximum of 30 years (

the specific

period will depend on the characteristic of the riverbed and its water availability);

(2)

will be subject

, in whole

or

in part,

to expiration for its non-use;

(3)

will have to

give

human consumption and sanitation priority in the use of water; and

(4)

will be subject to a minimum ecological flow to ensure nature conservation and environmental protection,

as

determined by the Water Authority. It shall be noted that the water regulation and its distribution is one of the most important focuses of the

constitutional convention

, and therefore, new changes may come into effect.

The Chilean Congress is considering a draft bill that declares lithium mining to be in the national interest, which if passed in its current form, could enable the expropriation of our lithium assets.

The Chilean

Congress is currently processing a bill, bulletin 10,638-08, which “Declares the exploitation and commercialization of lithium and Sociedad Química y Minera de Chile S.A. to be of national interest.” The purpose of this bill is to enable the potential expropriation of our assets, or our lithium operations in general. The bill is subject to further discussion in the Chilean

Congress, which includes several possible changes to its current wording. We cannot guarantee that the bill will not eventually be approved by the Chilean

Congress,

or

that its final wording will not refer to us or our lithium operations. If the bill is approved as currently drafted, it could have a material adverse effect on our business, financial condition and results of operations.

The Chilean government could levy additional taxes on mining companies operating in Chile.

In Chile, there is a royalty tax that is applied to mining activities developed in the country.

The Chilean Congress is currently processing a bill, bulletin 12,093-08, which proposes to institute a royalty fee of 3% on the value of extracted minerals. The bill is subject to further discussion in the Chilean Congress, which includes several possible changes to its current wording. We cannot guarantee that the bill will not eventually be approved by the Chilean Congress. If the bill is approved as currently drafted, it could have a material adverse effect on our business, financial condition and results of operations.

New

legislation

affecting mining licenses

could materially adversely affect our mining licenses and mining concessions

.

Law No. 21,420

,

published in the Official Gazette on February 4, 2022, reduces or eliminates certain tax exemptions in order to finance a new social security

program

called “Universal Guaranteed Pension”. Among others  changes, this law contemplates amendments to the Chilean Mining Code, such as

:

(i) the increase in the value of the mining licenses related to the mining concessions (

an

increase of at least 4 times the previous value); (ii) the modification of the term on which the

mining

exploration concessions are granted and the prohibition

on

the holder to

obtain

a new

mining

exploration concession in the same area once the previous

concession

has expired; and (iii) amendments to the mining concessions

award

process.

14

Ratification of the International Labor Organization’s Convention 169 concerning indigenous and tribal peoples might affect our development plans.

Chile, a member of the International Labor Organization (“ILO”), has ratified the ILO’s Convention 169 (the “Indigenous Rights Convention”) concerning indigenous and tribal people. The Indigenous Rights Convention established several rights for indigenous people and communities. Among other rights, the Indigenous Rights Convention states that (i) indigenous groups should be notified and consulted prior to the development of any project on land deemed indigenous, although veto rights are not mentioned, and (ii) indigenous groups have, to the extent possible, a stake in benefits resulting from the exploitation of natural resources in indigenous land. The extent of these benefits has not been defined by the Chilean government.

The Chilean government has addressed item (i) above through Supreme Decree No. 66, issued by the Social Development Ministry. This decree requires government entities to consult indigenous groups that may be directly affected by the adoption of legislative or administrative measures, and it also defines criteria for the projects or activities that must be reviewed through the environmental evaluation system that also require such consultation. To the extent that the new rights outlined in the Igndigenous Rights Convention become laws or regulations in Chile, judicial interpretations of the convention of those laws or regulations could affect the development of our investment projects in lands that have been defined as indigenous, which could have a material adverse effect on our business, financial condition and results of operations. The Chilean Supreme Court has consistently held that consultation processes must be carried out in the manner prescribed by the Indigenous Rights Convention.

The consultation process may cause delays in obtaining regulatory approvals, including environmental permits, as well as public opposition by local and/or international political, environmental and ethnic groups, particularly in environmentally sensitive areas or in areas inhabited by indigenous populations. Furthermore, the omission of the consultation process when required by law may result in the revocation or annulment of regulatory approvals, including environmental permits already granted.

Consequently, operating projects may be affected since the omission of the consultation process, when required by law, could lead to public law annulment actions pursuing the annulment of the environmental permits granted.

However, this risk frequently arises during the environmental assessment phase when the environmental

permits are to be obtained. In such scenario, affected parties may take several legal actions to declare null or void the environmental permits that omitted the consultation process, and in some cases, courts have overturned environmental approvals in which consultation was not made as prescribed in the Indigenous Rights Convention.

If the Indigenous Rights Convention affects our development plans, it could have a material adverse effect on our business, financial condition and results of operations.

Chile has different corporate disclosure and accounting standards than those you may be familiar with in the United States.

Accounting, financial reporting and securities disclosure requirements in Chile differ in certain significant

respects from those required in the United States. Accordingly, the information about us available to you will not be the same as the information available to holders of securities issued by a U.S. company. In addition, although Chilean law imposes restrictions on insider trading and price manipulation, applicable Chilean laws are different from those in the United States, and the Chilean securities markets are not as highly regulated and supervised as the U.S. securities markets.

15

Chile is located in a seismically active region.

Chile is prone to earthquakes because it is located along major fault lines. During 2017-2021, Chile has experienced several earthquakes which had a magnitude of over 6.0 on the Richter scale. There were also earthquakes in the past decade that caused substantial damage to some areas of the country. Chile has also experienced volcanic activity. A major earthquake or a volcanic eruption could have significant negative consequences for our operations and for the general infrastructure, such as roads, rail, and access to goods, in Chile. Although we maintain industry standard insurance policies that include earthquake coverage, we cannot assure you that a future seismic or volcanic event will not have a material adverse effect on our business, financial condition and results of operations.

Risks Relating to our Shares and to our ADSs

The price of our ADSs and the U.S. dollar value of any dividends will be affected by fluctuations in the U.S. dollar/Chilean peso exchange rate.

Chilean trading in the shares underlying our ADSs is conducted in Chilean pesos. The depositary for our ADSs will receive cash distributions that we make with respect to the shares in Chilean pesos. The depositary will convert such Chilean pesos to U.S. dollars at the then prevailing exchange rate to make dividend and other distribution payments in respect of ADSs. If the value of the Chilean peso falls relative to the U.S. dollar, the value of the ADSs and any distributions to be received from the depositary will decrease.

Developments in other emerging markets could materially affect the value of our ADSs and our shares.

The Chilean financial and securities markets are, to varying degrees, influenced by economic and market conditions in other emerging market countries or regions of the world. Although economic conditions are different in each country or region, investor reaction to developments in one country or region can have significant effects on the securities of issuers in other countries and regions, including Chile and Latin America. Events in other parts of the world may have a material effect on Chilean financial and securities markets and on the value of our ADSs and our shares.

The prices of securities issued by Chilean companies, including banks, are influenced to varying degrees by economic and market considerations in other countries. We cannot assure you that future developments in or affecting the Chilean economy, including consequences of economic difficulties in other markets, will not materially and adversely affect our business, financial condition or results of operations.

We are exposed to risks related to the weakness and volatility of the economic and political situation in Asia, the United States, Europe, other parts of Latin America and other nations. Although economic conditions in Europe and the United States may differ significantly from economic conditions in Chile, investors’ reactions to developments in these other countries may have an adverse effect on the market value of securities of Chilean issuers.

If these, or other nations’ economic conditions deteriorate, the economy in Chile, as both a neighboring country and a trading partner, could also be affected and could experience slower growth than in recent years, with possible adverse impact on our borrowers and counterparties.

16

The volatility and low liquidity of the Chilean securities markets could affect the ability of our shareholders to sell our ADSs.

The Chilean securities markets are substantially smaller, less liquid and more volatile than the major securities markets in the United States. The volatility and low liquidity of the Chilean markets could increase the price volatility of our ADSs and may impair the ability of a holder to sell our ADSs or to sell the shares underlying our ADSs into the Chilean market in the amount and at the price and time the holder wishes to do so.

Our share or ADS price may react negatively to future acquisitions, divestitures, capital increases and investments.

As world leaders in our core businesses, part of our strategy is to look for opportunities that will allow us to consolidate and strengthen our competitive position in jurisdictions in which we currently do not operate. Pursuant to this strategy, we may carry out acquisitions or joint ventures relating to any of our businesses or to new businesses in which we believe we may have sustainable competitive advantages.  We may also seek to strengthen our leadership position in our core businesses through divestitures of certain assets or stakes in subsidiaries that we believe will allow us to concentrate our efforts on our core businesses. Depending on our capital structure at the time of any acquisitions or joint ventures, we may need to raise significant debt and/or equity which will affect our financial condition and future cash flows. We may also carry out capital increases, such as the one undertaken in 2021, in order to raise capital for our capital plan. In addition, any divestitures we effect may not result in strengthening our position in our core businesses as anticipated. Any change in our financial condition could affect our results of operations and negatively impact our share or ADS price.  

ADS holders may be unable to enforce rights under U.S. securities laws.

Because we are a Chilean company subject to Chilean law, the rights of our shareholders may differ from the rights of shareholders in companies incorporated in the United States, and ADS holders may not be able to enforce or may have difficulty enforcing rights currently in effect under U.S. federal or state securities laws.

Our company is an open stock corporation incorporated under the laws of the Republic of Chile.  Most of our directors and officers reside outside the United States, principally in Chile.  All or a substantial portion of the assets of these persons are located outside the United States. As a result, if any of our shareholders, including holders of our ADSs, were to bring a lawsuit against our officers or directors in the United States, it may be difficult for them to effect service of legal process within the United States upon these persons. Likewise, it may be difficult for them to enforce judgments obtained in United States courts based upon the civil liability provisions of the federal securities laws in the United States against them in the United States.

In addition, there is no treaty between the United States and Chile providing for the reciprocal enforcement of foreign judgments. However, Chilean courts have enforced judgments rendered in the United States, provided that the Chilean court finds that the United States court respected basic principles of due process and public policy. Nevertheless, there is doubt as to whether an action could be brought successfully in Chile in the first instance on the basis of liability based solely upon the civil liability provisions of the United States federal securities laws.

As preemptive rights may be unavailable for our ADS holders, they have the risk of their holdings being diluted if we issue new stock.

Chilean laws require companies to offer their shareholders preemptive rights whenever issuing new shares of capital stock so shareholders can maintain their existing ownership percentage in a company.

17

If we increase our capital by issuing new shares, a holder may subscribe for up to the number of shares that would prevent dilution of the holder’s ownership interest.

If we issue preemptive rights, United States holders of ADSs would not be able to exercise their rights unless a registration statement under the Securities Act were effective with respect to such rights and the shares issuable upon exercise of such rights or an exemption from registration were available. We cannot assure holders of ADSs that we will file a registration statement or that an exemption from registration will be available. Although in connection with the 2021 capital increase, we filed a registration statement that permitted holders of ADSs to exercise preemptive rights, we may, in our absolute discretion, decide not to prepare and file such a registration statement in a future capital increase. If our ADS holders were unable to exercise their preemptive rights in a future capital increase because we do not file a registration statement, the ADS depositary would attempt to sell their rights and distribute the net proceeds from the sale to them, after deducting the depositary’s fees and expenses. If the ADS depositary is not able sell the rights, the rights would expire and have no further value and holders of ADSs would not realize any value from them. In either case, ADS holders’ equity interests in us would be diluted in proportion to the increase in our capital stock.

If we were classified as a Passive Foreign Investment Company by the U.S. Internal Revenue Service, there could be adverse consequences for U.S. investors.

We believe that we were not classified as a Passive Foreign Investment Company (“PFIC”) for

2021

.  Characterization as a PFIC could result in adverse U.S. tax consequences to a U.S. investor in our shares or ADSs.  For example, if we (or any of our subsidiaries) are a PFIC, our U.S. investors may become subject to increased tax liabilities under U.S. tax laws and regulations and will become subject to burdensome reporting requirements.  The determination of whether or not we (or any of our subsidiaries or portfolio companies) are a PFIC is made on an annual basis and will depend on the composition of our (or their) income and assets from time to time. See “Item 10.E. Taxation—Material United States Tax Considerations.”

Changes in Chilean tax regulations could have adverse consequences for U.S. investors.

Cash dividends paid by the Company with respect to the shares, including the shares represented by ADSs, will be subject to a Chilean withholding tax at a rate of 35%, less the credit available for corporate tax, which must be withheld and paid by the Company (the

“

Withholding Tax

”).

The effective rate of Withholding Tax imposed on dividends attributed to earnings in 2021 of the Company and distributed during the same period was 23.90412%.

Changes in Chilean tax regulations could have adverse consequences for U.S. investors.

18

General Risk Factors

Our measures to minimize our exposure to bad debt may not be effective and a significant increase in our accounts receivable coupled with the financial condition of customers may result in losses that could have a material adverse effect on our business, financial condition and results of operations.

Potentially negative effects of global economic conditions on the financial condition of our customers may include the extension of the payment terms of our accounts receivable and may increase our exposure to bad debt. While we have implemented certain safeguards, such as using credit insurance, letters of credit and prepayment for a portion of sales, to minimize the risk, we cannot assure you that such safeguards will be effective and a significant increase in our accounts receivable coupled with the financial condition of customers may result in losses that could have a material adverse effect on our business, financial condition and results of operations.

Quality standards in markets in which we sell our products could become stricter over time.

In the markets in which we do business, customers may impose quality standards on our products and/or governments may enact stricter regulations for the distribution and/or use of our products. As a result, if we cannot meet such new standards or regulations, we may not be able to sell our products. In addition, our cost of production may increase in order to meet any such newly imposed or enacted standards or regulations. Failure to sell our products in one or more markets or to important customers could materially adversely affect our business, financial condition and results of operations.

Our business is subject to many operating and other risks for which we may not be fully covered under our insurance policies.

Our facilities and business operations in Chile and abroad are insured against losses, damage or other risks by insurance policies that are standard for the industry and that would reasonably be expected to be sufficient by prudent and experienced persons engaged in businesses similar to ours.

We may be subject to certain events that may not be covered under our insurance policies, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, as a result of major earthquakes and unexpected rains and flooding in Chile, as well as other natural disasters worldwide, conditions in the insurance market have changed and may continue to change in the future, and as a result, we may face higher premiums and reduced coverage, which could have a material adverse effect on our business, financial condition and results of operations.

Our water supply could be affected by geological changes or climate change.

Our access to water may be impacted by changes in geology, climate change or other natural factors, such as wells drying up or reductions in the amount of water available in the wells or rivers from which we obtain water, that we cannot control. The use of seawater for future or current operations could increase our operating costs. Any such change may have a material adverse effect on our business, financial condition and results of operations.

Any loss of key personnel may materially and adversely affect our business.

Our success depends in large part on the skills, experience and efforts of our senior management team and other key personnel. The loss of the services of key members of our senior management or employees with critical skills could have a negative effect on our business, financial condition and results of operations. If we are not able to attract or retain highly skilled, talented and qualified senior managers or other key personnel, our ability to fully implement our business objectives may be materially and adversely affected.

We are subject to Chilean and international anti-corruption, anti-bribery, anti-money laundering and international trade laws. Failure to comply with these laws could adversely impact our business, financial condition and results of operations.

We are required to be in compliance with all applicable laws and regulations in Chile and internationally with respect to anti-corruption, anti-money laundering and other regulatory matters, including the FCPA. Although we and our subsidiaries maintain policies and processes intended to comply with these laws, we cannot ensure that these compliance policies and processes will prevent intentional, reckless or negligent acts committed by our officers or employees.

19

If we or our subsidiaries fail to comply with any applicable anti-corruption, anti-bribery, anti-money laundering or other similar laws, we and our officers and employees may be subject to criminal, administrative or civil penalties and other remedial measures, which could have material adverse effects on our and our subsidiaries’ business, financial condition and results of operations. Any investigation of potential violations of anti-corruption, anti-bribery or anti-money laundering laws by governmental authorities in Chile or other jurisdictions could result in an inability to prepare our consolidated financial statements in a timely manner. This could adversely impact our reputation, ability to access the financial markets and ability to obtain contracts, assignments, permits and other government authorizations necessary to participate in our and our subsidiaries’ industry, which, in turn, could have adverse effects on our and our subsidiaries’ business, financial condition and results of operations.

We are subject to risks related to the ongoing military conflict between Ukraine and Russia and it may have a material adverse effect on our business, financial condition and results of operations

On February 24, 2022, Russia launched a military invasion of Ukraine. The ongoing military conflict between Russia and Ukraine has provoked strong reactions from the United States, the UK, the European Union and various other countries around the world, including the imposition of broad financial and economic sanctions against Russia. While the precise effects of the ongoing military conflict and these sanctions on the Russian and global economies remain uncertain, they have already resulted in significant volatility in financial markets as well as in an increase in energy and commodity prices globally. Should the conflict continue or escalate, markets may face various economic and security consequences including, but not limited to, supply shortages of different kinds, further increases in prices of commodities, including

natural

gas, oil

, fertilizers

and agricultural goods, significant disruptions in logistics infrastructure, telecommunications services, the risk of unavailability of information technology systems and infrastructure, among others, given that Russia and Ukraine are significant exporters of commodities. The resulting impacts on financial markets, inflation, interest rates, unemployment and other matters could disrupt the global economy. Other potential consequences include, but are not limited to, growth in the number of popular uprisings in the region, increased political discontent, especially in the regions most affected by the conflict or economic sanctions, increase in cyberterrorism activities and attacks, displacement of persons to regions close to the areas of conflict and an increase in the number of refugees fleeing across Europe, among other unforeseen social and humanitarian effects.

ITEM 4.INFORMATION ON THE COMPANY

4.A.  History and Development of the Company

Historical Background

Sociedad Química y Minera de Chile S.A. is an open stock corporation organized under the laws of the Republic of Chile. We were constituted by public deed issued on June 17, 1968 by the Notary Public of Santiago, Mr. Sergio Rodríguez Garcés. Our existence was approved by Decree No. 1,164 of June 22, 1968 of the Ministry of Finance, and we were registered on June 29, 1968 in the Registry of Commerce of Santiago, on page 4,537 No. 1,992. Our headquarters is located at El Trovador 4285, Fl. 6, Las Condes, Santiago, Chile. Our telephone number is +56 2 2425-2000. We are legally referred to by our full name Sociedad Química y Minera de Chile S.A. as well as commercially by the abbreviated name “SQM.” Our Website is www.sqm.com.

Commercial exploitation of the caliche ore deposits in northern Chile began in the 1830s, when sodium nitrate was extracted from the ore for use in the manufacturing of explosives and fertilizers. By the end of the nineteenth century, nitrate production had become the leading industry in Chile, and the country was the world’s leading supplier of nitrates. The accelerated commercial development of synthetic nitrates in the 1920s and the global economic depression in the 1930s caused a serious contraction of the Chilean nitrate business, which did not recover significantly until shortly before the Second World War.  After the war, the widespread commercial production of synthetic nitrates resulted in a further contraction of the natural nitrate industry in Chile, which continued to operate at depressed levels into the 1960s. 

We were formed in 1968 through a joint venture between Compañía Salitrera Anglo Lautaro S.A. (“Anglo Lautaro”) and Corfo, a Chilean government entity. In 1971, Anglo Lautaro sold all of its shares to Corfo, and we were wholly owned by the Chilean government until 1983. In 1983, Corfo began a process of privatization by selling our shares to the public and subsequently listing such shares on the Santiago Stock Exchange. By 1988, all of our shares were publicly owned. Our ADSs have traded on the NYSE under the ticker symbol “SQM” since 1993. Each ADS represents one Series B common share. We have from time to time accessed international capital markets for the issuance of additional ADSs in, including most recently the US$1.1 billion capital increase in 2021.

Since our inception, we have produced nitrates and iodine, which are obtained from the caliche ore deposits in northern Chile. In 1985, we began to use heap leaching processes to extract nitrates and iodine, and in 1986 we started to produce potassium nitrate at our Coya Sur facility. Between 1994 and 1999, we invested approximately US$300 million in the development of the Salar de Atacama project in northern Chile, which has enabled us to produce potassium chloride, lithium carbonate, lithium hydroxide, potassium sulfate and boric acid.

From 2000 through 2004, we principally consolidated the investments carried out in the preceding five years. We focused on reducing costs and improving efficiencies throughout the organization.

Starting in 2005, we began strengthening our leadership position in our core businesses through a combination of capital expenditures and advantageous acquisitions and divestitures.

Our capital expenditure program has allowed us to add new products to our product lines and increase the production capacity of our existing products. In 2005, we started production of lithium hydroxide at a plant in the Carmen Lithium production facility, near the city of Antofagasta in the north of Chile. In 2007, we completed the construction of a new prilling and granulating plant for nitrates in Coya Sur. In 2011, we completed expansions of our lithium carbonate capacity, achieving 48,000 metric tons of capacity per year. Since 2010, we have continued to expand our production capacity of potassium products in our operations in the Salar de Atacama. In 2011, we completed the construction of a new potassium nitrate facility in Coya Sur, increasing our overall production capacity of potassium nitrate by 300,000 metric tons per year. In 2013, we completed expansions in the production capacity of our iodine plants in Nueva Victoria.  Our capital expenditure program also includes exploration for metallic minerals. Our exploration efforts have led to discoveries that in some cases may result in sales of the discovery and the generation of royalty income in the future. Within this context, in 2013 we sold our royalty rights to the Antucoya mining project to Antofagasta Minerals.

In 2014, we invested in the development of new extraction sectors and production increases in both nitrates and iodine at Nueva Victoria, reaching an approximate production capacity (including the Iris facility) of 8,500 metric tons per year of iodine at the facility.

In 2015, we focused on increasing the efficiency of our operations. Within this context, we announced a plan to restructure our iodine and nitrate operations. In an effort to take advantage of our highly efficient production facilities at our Nueva Victoria site, we decided to suspend the mining and nitrate operations and reduce iodine production at our Pedro de Valdivia site. During 2017, we increased our iodine production capacity at Nueva Victoria to approximately 10,000 metric tons per year. We continued expanding our iodine capacity in 2018, which, including Pedro de Valdivia and Nueva Victoria, reached approximately 14,000 metric tons per year.

21

In 2016, we entered into a 50/50 joint venture with Lithium Americas to develop the Minera Exar lithium project in Caucharí-Olaroz in the Jujuy province of Argentina. Our interest was sold to Ganfeng Lithium Netherlands Co., BV in 2018. Ganfeng is responsible for a US$50 million deferred payment to us if certain sales goals are met by the project

. In 2016, we also made a capital contribution of US$20 million to Elemental Minerals Limited (“Elemental Minerals”), an Australian based company whose main assets are various potassium deposits in the Republic of Congo.

In 2017, we entered into a 50/50 joint venture with respect to the Mt. Holland lithium project to design, construct and operate a mine, concentrator and refinery for the production of lithium hydroxide.

On September 23, 2019, Wesfarmers Limited (“Wesfarmers”) acquired all the issued ordinary shares in our joint venture partner and became a 50% partner in the Mt. Holland lithium project in the joint venture with SQM Australia Pty.

In October 2020, we announced our Sustainable Development Plan, which includes voluntarily expanding our monitoring systems, promoting better and more meaningful conversations with neighboring communities, becoming carbon neutral and reducing water by 65% and brine extraction by 50%. As part of this plan, we also set a goal to obtain international certifications and participate in international sustainability indices.

In 2021, in the Salar de Atacama, we began preparing an external audit in IRMA’s rigorous responsible mining certification process.

On February 16, 2021, our Board approved the investment of approximately US$700 million for our 50% share of the development costs of the Mt. Holland lithium hydroxide project in the joint venture with Wesfarmers. During 2021, our lithium carbonate production in Chile reached an effective capacity of 120,000 metric tons and we expect to increase this to 180,000 metric tons and our lithium hydroxide capacity to 30,000 metric tons during 2022.

In November 2021, we were accepted into the Dow Jones Sustainability Chile and the Dow Jones Sustainability MILA Pacific Alliance Indices for the second year in a row

.

Capital Expenditure Program

We regularly review different opportunities to improve our production methods, reduce costs, increase production capacity of existing products and develop new products and markets. Additionally, significant capital expenditures are required every year in order to sustain our production capacity. We are focused on developing new products in response to identified customer demand, as well as new products that can be derived as part of our existing production or other products that could fit our long-term development strategy. Our capital expenditures in Chile have been mainly related to the organic growth and sustainability of our business, including the construction of new facilities and the renovation of plants and equipment. In 2021, we also worked on the expansion of our lithium carbonate and lithium hydroxide capacity in Chile, which reached 120,000 metric tons and 21,500 metric tons respectively by the end of 2021. We also began expansions related to the mining and production facilities of nitrates and iodine in Chile and lithium hydroxide in Western Australia. 

22

Our capital expenditures for the years ended December 31, 2021, 2020 and 2019 were as follows:

(in millions of US$)	2021		2020		2019
Capital expenditures		471.5		322.2		321.3

During 2021, we had total capital expenditures of US$471.5 million. Our 2021 capital expenditure was primarily related to:

· Capacity expansion projects related to the completion of our increase of our lithium carbonate production in Chile from 70,000 metric tons per year to 120,000 metric tons per year and investment in our lithium carbonate production from 120,000 to 180,000 metric tons per year;

· Completion of capacity expansion of lithium hydroxide production in Chile from 13,500 metric tons per year to 21,500 metric tons per year and commencement of a further capacity expansion of lithium hydroxide production in Chile from 21,500 metric tons per year to 30,000 metric tons per year;

· Investment in our new 50,000 metric ton lithium hydroxide facility in Western Australia;

· Optimization projects related to iodine production plants in Nueva Victoria; and

· General maintenance of all production units in order to ensure the fulfillment of production and sales targets.

During 2020, we had total capital expenditures of US$322.2 million, a decrease compared to the US$450 million that was originally expected as a result in the delay of the purchasing of equipment. Our 2020 capital expenditure was primarily related to:

· Capacity expansion projects related to the increase of our lithium carbonate production in Chile from 70,000 metric tons per year to 120,000 metric tons per year;

· Capacity expansion of lithium hydroxide production in Chile from 13,500 metric tons per year to 21,500 metric tons per year;

· Optimization projects related to potassium nitrate production plants in Coya Sur; and

· General maintenance of all production units in order to ensure the fulfillment of production and sales targets.

During 2019, we had total capital expenditures of US$321.3 million, primarily related to:

· Capacity expansion projects related to the completion of the increase of our lithium carbonate production in Chile to 70,000 metric tons per year and the commencement of our lithium carbonate expansion project in Chile to reach 120,000 metric tons per year.

· Capacity expansion of lithium hydroxide production in Chile from 13,500 metric tons per year to 21,500 metric tons per year;

· Investments to increase iodine capacity to 14,800 metric tons per year in the Nueva Victoria mine; and

· Capacity expansion and optimization projects related to potassium nitrate production plants II, III and IV in Coya Sur.

We believe that our capital expenditures for 2022 could reach approximately US$900 million focused on the increase of our production capacity, primarily related to lithium carbonate and lithium hydroxide capacity expansions and nitrates and iodine capacity in Chile, and development of our lithium project in Australia, as well as the maintenance of our production facilities in order to strengthen our ability to meet our production goals. We expect our installed capacity of lithium carbonate and lithium hydroxide in Chile to reach approximately 180,000 and 30,000 metric tons, respectively, during the first half of 2022. We will also begin the investment in a new lithium expansion in Chile, increasing lithium carbonate and lithium hydroxide capacity to approximately 210,000 and 40,000 metric tons, respectively, by 2024. We will also invest heavily in our Mt. Holland lithium project in Western Australia through the purchase of necessary equipment and continuing the construction of the project.

23

In addition, we will begin

investments in the Pampa Orcoma project in the Tarapacá Region of Chile to increase effective iodine capacity by approximately 2,500 metric tons, and increase our nitrate salts production by 320,000 metric tons, including the use of 200 liters/second of seawater for the leaching operation.

Production is expected to start during 2024.

4.B. Business Overview

The Company

We believe that we are the world’s largest producer of potassium nitrate and iodine and one of the world’s largest lithium producers. We also produce specialty plant nutrients, iodine derivatives, lithium derivatives, potassium chloride, potassium sulfate and certain industrial chemicals (including industrial nitrates and solar salts). Our products are sold in approximately 110 countries through our worldwide distribution network, with 92% of our sales in 2021 derived from countries outside Chile.

Our products are mainly derived from mineral deposits found in northern Chile. We mine and process caliche ore and brine deposits. The caliche ore in northern Chile contains the only known nitrate and iodine deposits in the world and is the world’s largest commercially exploited source of natural nitrates. The brine deposits of the Salar de Atacama, a salt-encrusted depression in the Atacama Desert in northern Chile, contain high concentrations of lithium and potassium as well as significant concentrations of sulfate and boron.

From our caliche ore deposits, we produce a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, we extract brines rich in potassium, lithium, sulfate and boron in order to produce potassium chloride, potassium sulfate, lithium solutions and bischofite (magnesium chloride). We produce lithium carbonate and lithium hydroxide at our plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama. We market all of these products through an established worldwide distribution network.

Our products are divided into six categories: specialty plant nutrients; iodine and its derivatives; lithium and its derivatives; potassium chloride and potassium sulfate; industrial chemicals and other commodity fertilizers. Specialty plant nutrients are premium fertilizers that enable farmers to improve yields and the quality of certain crops. Our main specialty fertilizer is potassium nitrate, which is used primarily in high-value crops. Iodine and its derivatives are mainly used in the X-ray contrast media and biocides industries and in the production of polarizing film, which is an important component in LCD screens. Lithium and its derivatives are mainly used in batteries, greases and frits for production of ceramics. Potassium chloride is a commodity fertilizer that is produced and sold by us worldwide. Potassium sulfate is a specialty fertilizer used primarily in crops such as vegetables, fruits and industrial crops. Industrial chemicals have a wide range of applications in certain chemical processes such as the manufacturing of glass, explosives and ceramics. Industrial nitrates are also being used in concentrated solar power plants as a means for energy storage. In addition, we complement our product portfolio through the buying and selling of other fertilizers in Chile and around the world.

For the year ended December 31, 2021, we had revenues of US$2,862.3 million, gross profit of US$1,090.1 million and profit attributable to controlling interests of US$585.5 million. Our worldwide market capitalization as of December 31, 2021 was approximately US$15.5 billion.

Specialty Plant Nutrition

: We produce four main types of specialty plant nutrients which offer nutritional solutions for fertigation, direct soil and foliar fertilizer applications: potassium nitrate, sodium nitrate, sodium potassium nitrate and specialty blends. We also sell other specialty fertilizers including third party products. All of these products are used in either solid or liquid form mainly on high value crops such as fruit, flowers and some vegetables. These fertilizers are widely used in crops that use modern agricultural techniques such as hydroponics, greenhouses and crops with foliar application and fertigation (in the latter case, the fertilizer is dissolved in water before irrigation).

24

Specialty plant nutrients have certain advantages over commodity fertilizers, such as rapid and effective absorption (without requiring nitrification), superior water solubility, increased soil pH (which reduces soil acidity) and low chloride content. One of the most important products in this business line is potassium nitrate, which is sold in crystalline or prill form, allowing for different application methods. Crystalline potassium nitrate products are ideal for application by fertigation and foliar applications, and potassium nitrate prills are suitable for direct soil applications.

We have developed brands for marketing according to the different applications and uses of our products. Our main brands are: Ultrasol

R

(fertigation), Qrop

R

(soil application), Speedfol

R

(foliar application) and Allganic

R

(organic agriculture).

The new needs of more sophisticated customers demand that the industry provide integrated solutions rather than individual products. Our products, including customized specialty blends that meet specific needs along with the agronomic service provided, allow us to create plant nutrition solutions that add value to crops through higher yields and better-quality production. Because our products are derived from natural nitrate compounds or natural potassium brines, they have certain advantages over synthetically produced fertilizers. One of the advantages of our products is the presence of certain beneficial trace elements, which makes them more valuable for customers who prefer products of natural origin. As a result, specialty plant nutrients are sold at a premium price compared to commodity fertilizers.

Iodine and its Derivatives:

We believe that we are the world’s leading producer of iodine and iodine derivatives, which are used in a wide range of medical, pharmaceutical, agricultural and industrial applications, including x-ray contrast media, polarizing films for LCD and LED, antiseptics, biocides and disinfectants, in the synthesis of pharmaceuticals, electronics, pigments and dye components.

Lithium and its Derivatives

: We are a leading producer of lithium carbonate, which is used in a variety of applications, including electrochemical materials for batteries used in electric vehicles, portable computers, tablets, cellular telephones and electronic apparatus, frits for the ceramic and enamel industries, heat-resistant glass (ceramic glass), air conditioning chemicals, continuous casting powder for steel extrusion, pharmaceuticals and lithium derivatives. We are also a leading supplier of lithium hydroxide, which is primarily used as an input for the lubricating greases industry and for cathodes for high energy capacity batteries.

Potassium:

We produce potassium chloride and potassium sulfate from brines extracted from the Salar de Atacama. Potassium chloride is a commodity fertilizer used to fertilize a variety of crops including corn, rice, sugar, soybean and wheat. Potassium sulfate is a specialty fertilizer used mainly in crops such as vegetables, fruits and industrial crops.

Industrial Chemicals

: We produce and sell three industrial chemicals: sodium nitrate, potassium nitrate and potassium chloride. Sodium nitrate is used primarily in the production of glass, explosives, and metal treatment, metal recycling and the production of insulation materials, among other uses. Potassium nitrate is used in the manufacturing of specialty glass, and it is also an important raw material for the production of frits for the ceramics, enamel industries, metal treatment and pyrotechnics. Solar salts, a combination of potassium nitrate and sodium nitrate, are used as a thermal storage medium in concentrated solar power plants. Potassium chloride is a basic chemical used to produce potassium hydroxide, and it is also used as an additive in oil drilling as well as in food processing, among other uses.

25

Other Products and Services:

We also sell other fertilizers and blends, some of which we do not produce. We are the largest company that produces and distributes the three main potassium sources: potassium nitrate, potassium sulfate and potassium chloride.

27

New Business Ventures

We constantly evaluate opportunities that are consistent with our existing and new businesses. We seek to acquire interests in projects both inside and outside of Chile where we believe we have sustainable competitive advantages, and we hope to continue doing so in the future.

In addition, we are actively conducting exploration for metallic minerals in the mining properties we own. If such minerals are found, we may decide to exploit, sell or enter into an association to extract these resources. Our exploration efforts are currently focused on the layer of bedrock that lies beneath the caliche ore that we use as the primary raw material in the production of iodine and nitrates. This bedrock has significant potential for metallic mineralization, particularly copper and gold. A significant portion of our mining properties are located in the Antofagasta region of Chile, where many large copper producers operate.

We have an in-house geological exploration team that explores the area directly, identifying drilling targets and assessing new prospects. In 2021, the team has confirmed the existence of high-grade copper and gold mineralization at the Bufalo project, located 120 kilometers east of the city of Antofagasta. The Bufalo project corresponds to a district that hosts several mineralized bodies of copper, copper-gold and copper-gold-silver in which SQM has already drilled nearly 99,000 meters of drilling, using our own diamond and RC drilling machines. We also have a metal business development team that works to engage partners interested in investing in metal exploration within our mining properties. As of February 2022, we had three option agreements in place with four mining companies and private equity firms. We participated in the formation of two joint ventures as a result of exercising an option agreement with a junior mining company.

Main Business Lines

Specialty Plant Nutrition

In 2021, specialty plant nutrients revenues increased to US$908.8 million, representing 31.8% of our total revenues for that year. We believe that we are the world’s largest producer of potassium nitrate. We estimate that our 2021 sales volume represented approximately 51% of the total global potassium nitrate used for all applications, remaining flat with our sales volume in 2020. We estimate that our sales accounted for approximately 51% of global potassium nitrate sales for all agricultural uses by volume in 2021. During 2021, the agricultural potassium nitrate market increased approximately 4% when compared to 2020. These estimates do not include potassium nitrate produced and sold locally in China, only Chinese net imports and exports.

In addition to potassium nitrate, we produce the following specialty plant nutrients: sodium nitrate, sodium potassium nitrate and specialty blends (containing various combinations of nitrogen, phosphate and potassium and generally known as “NPK blends”).

Our specialty plant nutrients have specific characteristics that increase productivity and enhance quality when used on certain crops and soils. The products have significant advantages for certain applications over commodity fertilizers based on other sources of nitrogen and potassium, such as urea and potassium chloride.

The advantages of our specialty plant nutrients include that they:

· are fully water soluble, allowing their more efficient use in hydroponics, fertigation, foliar applications and other advanced agricultural techniques thus reducing the water use associated with cultivating the crops;

· are chloride-free, which prevents toxicity in certain crops associated with high levels of chlorine in plant nutrients;

28

· provide nitrogen in nitric form, thereby allowing crops to absorb nutrients faster than they absorb urea- or ammonium-based fertilizers;

· do not release hydrogen after application, thereby avoiding increased soil acidity;

· possess trace elements, which promote disease resistance in plants; and

· are more attractive to customers who prefer products of natural origin.

Specialty Plant Nutrition: Market

The target market for our specialty plant nutrients includes producers of high-value crops such as vegetables, fruits, industrial crops, flowers, cotton and others. Furthermore, we sell specialty plant nutrients to producers of chloride-sensitive crops. Since 1990, the international market for specialty plant nutrients has grown at a faster rate than the international market for commodity-type fertilizers. This is mostly due to: (i) the application of new agricultural technologies such as fertigation and hydroponics, and the use of greenhouses; (ii) the increase in the cost of land and the scarcity of water, which has forced farmers to improve their yields and reduce water use; and (iii) the increase in demand for higher quality crops.

Over the last ten years, the compound annual growth rate for vegetable production per capita was 3%, while the compound annual growth rate for the world population was closer to 1%.

Worldwide scarcity of water and arable land drives the development of new agricultural techniques to maximize the use of these resources. A good example of this is the more efficient use of water through irrigation, which has grown at an average annual rate of 1% during the last 20 years (a pace similar to population growth). Micro-irrigation, which results in even more efficient use of water, has grown at 10% per year over the same period. Micro-irrigation systems, which include drip irrigation and micro-sprinklers, are the most efficient forms of technical irrigation. These applications require fully water-soluble plant nutrients. Our nitrate-based specialty plant nutrients are fully soluble in water and provide nitrogen in nitric form, which helps crops absorb these nutrients faster than they absorb urea- or ammonium-based fertilizers, facilitating a more efficient application of nutrients to the plant and thereby increasing the crop’s yield and improving its quality.

The lowest global share of hectares under micro-irrigation over total irrigated hectares is in Asia, with a figure of approximately 3%. This represents a high potential for the introduction of micro-irrigation in that region, which is reflected in the high growth rates in Asia in recent years.

Potassium nitrate is an important market in China, although currently its demand is largely fulfilled by domestic producers. Total demand of potassium nitrate in Asian countries totals approximately 400,000 to 420,000 metric tons, of which approximately 130,000 metric tons is needed for the tobacco industry and approximately 120,000 metric tons is related to the horticulture business. Of the total, between 15,000 and 35,000 metric tons of potassium nitrate are imports.

Specialty Plant Nutrition: Our Products

Potassium nitrate, sodium potassium nitrate, and specialty blends are higher margin products that use sodium nitrate as a feedstock. These products can be manufactured in crystallized or prilled form. Specialty blends are produced using our own specialty plant nutrients and other components at blending plants operated by us or our affiliates and related companies in Brazil, Chile, China, Italy, Mexico, the Netherlands, Peru, South Africa, Spain, and the United States.

Total revenues (in US$ millions)		908.8		701.7		723.9

(1) Includes Yara’s products sold pursuant to our commercial agreement.

(2) Includes trading of other specialty fertilizers.

In 2021, our specialty plant nutrients revenues increased to US$908.8 million, representing 32% of our total revenues for that year and a 29.5% increase from US$701.7 million in specialty plant nutrients revenues in 2020. Prices increased approximately 16.3% in 2021.

Depending on the systems used to apply specialty nutrients, fertilizers can be classified as specialty field fertilizers or water-soluble fertilizers.

Specialty field fertilizers are applied directly to the soil, manually or in a mechanized fashion. Their high solubility levels, lack of chloride and absence of acidic reactions make them particularly advantageous for tobacco, potatoes, coffee, cotton, and certain fruits and vegetables.

Water-soluble fertilizers are specialty nutrients that are delivered to the crops using modern irrigation systems. As these systems feature refined technology, the products used in them must be highly soluble, rich in nutrients, free of impurities and insoluble substances, and with a low salinity index. The leading nutrient in this segment is potassium nitrate, whose optimal balance of nitric nitrogen and chloride-free potassium (the two macronutrients most needed by plants) make it an indispensable source of nutrition for crops that use modern irrigation systems.

Potassium nitrate is widely known to be a vital component in foliar feeding applications, where usage is recommended in order to stave off nutritional deficiencies before the first symptoms appear, correct any deficiencies that arise and prevent physiological stress. This nutrient also helps promote a suitable balance between fruit production and/or growth, and plant development, particularly in crops with physiological disorders.

Foliar feeding with potassium nitrate can have beneficial effects:

· when soil chemistry limits nutrient solubility and availability (pH, organic matter, type and percentage of clay);

· when nutrient absorption through the roots is limited as a result of conditions that hamper root growth (temperature, moisture, oxygen and loss of soil structure);

· when the plant’s internal demand may surpass real internal nutrient redistribution capacity, leaving the demand unsatisfied;

· when nutrient mobility is limited, such as when plants flower before the leaf growth phase, imposing limiting factors on xylem nutrient transport; and

· to achieve rapid recovery from leaf stress caused by climatic conditions, soil conditions and irrigation management.

We have restructured the Qrop products portfolio to include a chloride-free line for direct application to the soil with a variety of specialized formulas and unique mixtures, which make these products highly accurate and quickly available for the plant. Ultrasolution K® addresses the need for potassium-free chloride and a nitrate safe for handling in the liquid fertilizer market, opening new opportunities for SQM in in the cultivation of almonds and strawberries, in which water quality and efficiency are very important.

30

During 2021, through our research and development team

, we continued the development of

products such as Ultrasoline®, Ultrasol K Acid®, ProP® and Prohydric®. Ultrasoline® is a new product that, together with potassium nitrate, incorporates iodine, an essential element for plants, allowing better root growth, optimal photosynthesis and better tolerance to oxidative stress, among other advantages.

Specialty Plant Nutrition: Marketing and Customers

In 2021, we sold our specialty plant nutrients in approximately 103 countries and to more than 1,200 customers. No customer represented more than 10% of our specialty plant nutrition revenues during 2021, and our ten largest customers accounted in the aggregate for approximately

28

% of revenues during that period. No supplier accounted for more than 10% of the costs of sales for this business line.

The table below shows the geographical breakdown of our revenues:

Revenues breakdown	2021			2020			2019
North America		35	%		35	%		34	%
Europe		20	%		21	%		21	%
Chile		15	%		14	%		15	%
Central and South America (excluding Chile)		10	%		10	%		11	%
Asia and Others		21	%		20	%		20	%

We sell our specialty plant nutrition products globally mainly through our own worldwide network of commercial offices and distributors.

We maintain inventory of our specialty plant nutrients in our commercial offices in our main markets in order to facilitate prompt deliveries to customers. Sales are made pursuant to spot purchase orders or short-term contracts.

As part of our marketing strategy, we provide technical and agronomical assistance to our clients. We have specific knowledge resulting from extensive research and numerous studies conducted by our agronomical teams in close contact with producers throughout the world. The solid agronomical knowledge is key for the development of specific formulas and hydroponic and fertigation nutritional plans, which allows us to provide expert advice for producing crops that meet high quality standards for the most efficient markets and in the most environmentally challenging conditions.

By working closely with our customers, we are able to identify their needs for new products and a possible existence of higher-value-added markets. Our specialty plant nutrients are used on a wide variety of crops, particularly value-added crops, where the use of our products enables our customers to increase yields and achieve a premium price for their products.

Our customers are located in diverse latitudes. Consequently, we do not believe there are any seasonal or cyclical factors that can materially affect the sales of our specialty plant nutrients.

Specialty Plant Nutrition: Fertilizer Sales in Chile

We market specialty plant nutrients in Chile through our subsidiary Soquimich Comercial S.A. (“SQMC”).

31

SQMC is one of the main players in the Chilean market, offering a wide range of products developed specifically for the crops grown in the country which require specialty plant nutrients.

SQMC sells local products as well as products imported from different countries around the world.

All contracts and agreements between SQMC and its foreign suppliers of fertilizers contain standard and customary commercial terms and conditions. SQMC has been able to obtain adequate supplies of these products with good pricing conditions.

SQMC’s total sales reached US$159 million and US$118 million in 2021 and 2020, respectively. During 2021, no client represented more than 10% of the sales of the Company. According to the customs information related to fertilizers, the market participation of fertilizers imported directly by SQMC during 2021 was approximately 24%.

Specialty Plant Nutrition: Competition

The principal means of competition in the sale of potassium nitrate are product quality, customer service, location, logistics, agronomic expertise and price.

We believe that we are the world’s largest producer of sodium nitrate and potassium nitrate for agricultural use. Our sodium nitrate products compete indirectly with specialty and commodity substitutes, which may be used by some customers instead of sodium nitrate depending on the type of soil and crop to which the product will be applied. Such substitute products include calcium nitrate, ammonium nitrate and calcium ammonium nitrate.

In the potassium nitrate market, our largest competitor is Haifa Chemicals Ltd. (“Haifa”), in Israel, which is a subsidiary of Trans Resources International Inc. We estimate that sales of potassium nitrate by Haifa accounted for approximately 17% of total world sales during 2021 (excluding sales by Chinese producers to the domestic Chinese market). Our sales accounted for approximately 51% of global potassium nitrate sales by volume for the period.

ACF, another Chilean producer, mainly oriented to iodine production, has produced potassium nitrate from caliche ore and potassium chloride since 2005. Kemapco, a Jordanian producer owned by Arab Potash, produces potassium nitrate in a plant located close to the Port of Aqaba, Jordan. In addition, there are several potassium nitrate producers in China, the largest of which are Yuantong and Migao. Most of the Chinese production is consumed by the Chinese domestic market.

In Chile, our products mainly compete with imported fertilizer blends that use calcium ammonium nitrate or potassium magnesium sulfate. Our specialty plant nutrients also compete indirectly with lower-priced synthetic commodity-type fertilizers such as ammonia and urea, which are produced by many producers in a highly price-competitive market. Our products compete on the basis of advantages that make them more suitable for certain applications as described above.

Iodine and its Derivatives

We believe that we are the world’s largest producer of iodine. In 2021, our revenues from iodine and iodine derivatives amounted to US$437.9 million, representing 15.3% of our total revenues in that year. We estimate that our sales accounted for approximately 31% of global iodine sales by volume in 2021.

Iodine: Market

Iodine and iodine derivatives are used in a wide range of medical, agricultural and industrial applications as well as in human and animal nutrition products. Iodine and iodine derivatives are used as raw materials or catalysts in the formulation of products such as X-ray contrast media, biocides, antiseptics and disinfectants, pharmaceutical intermediates, polarizing films for LCD and LED screens, chemicals, organic compounds and pigments. Iodine is also added in the form of potassium iodate or potassium iodide to edible salt to prevent iodine deficiency disorders.

32

X-ray contrast media is the leading application of iodine, accounting for approximately 24% of demand. Iodine’s high atomic number and density make it ideally suited for this application, as its presence in the body can help to increase contrast between tissues, organs, and blood vessels with similar X-ray densities. Other applications include pharmaceuticals, which we believe account for 13% of demand; LCD and LED screens, 13%; iodophors and povidone-iodine, 8%; animal nutrition, 8%; fluoride derivatives, 7%; biocides, 6%; nylon, 4%; human nutrition, 4% and other applications, 14%.

During 2021, the demand for iodine had a significant recovery compared to 2020, and exceeded the demand levels of 2019. Main drivers of this increase were in the X-ray contrast media market, in which demand grew by 14-15% compared to 2020, mainly due to worldwide growth in the healthcare industry spending during the year and increased accessibility to these types of treatments in emerging economies, mainly China. Another application for which demand increased above the market average was polarizing films for screens, growing around 6% compared to 2020, due to the reduction in TV costs, increased screen sizes and home office and home school trends as a result of the pandemic.

Iodine: Our Products

We produce iodine in our Nueva Victoria plant, near Iquique, and our Pedro de Valdivia plant, close to María Elena. We have a total production capacity of approximately 16,000 metric tons per year of iodine, including the Iris plant, which is located close to the Nueva Victoria plant.

Through ASG, we produce organic and inorganic iodine derivatives. ASG was established in the mid-1990s and has production plants in the United States, Chile and France. ASG is one of the world’s leading inorganic and organic iodine derivatives producer.

Consistent with our business strategy, we are constantly working on the development of new applications for our iodine-based products, pursuing a continuing expansion of our businesses and maintaining our market leadership.

We manufacture our iodine and iodine derivatives in accordance with international quality standards and have qualified our iodine facilities and production processes under the ISO 9001:2015 program, providing third party certification of the quality management system and international quality control standards that we have implemented.

The following table shows our total sales volumes and revenues from iodine and iodine derivatives for 2021, 2020 and 2019:

	2021		2020		2019

Our revenues increased to US$437.9 million in 2021 from US$334.7 million in 2020. This increase was primarily attributable to higher sales volumes and higher average prices during 2021. Average iodine prices were more than 2.8% higher in 2021 than in 2020. Our sales volumes increased 27.2% in 2021.

Iodine: Marketing and Customers

In 2021, we sold our iodine products in approximately 52 countries to approximately 260 customers, and most of our sales were exports. Two customers each accounted for more than 10% of our iodine revenues in 2021. These two customers accounted for approximately 42% of revenues, and our ten largest customers accounted in the aggregate for approximately 77% of revenues. No supplier accounted for more than 10% of the cost of sales of this business line.

The following table shows the geographical breakdown of our revenues:

Revenues breakdown	2021			2020			2019
North America		23	%		27	%		24	%
Europe		40	%		42	%		33	%
Chile		0	%		0	%		0	%
Central and South America (excluding Chile)		2	%		3	%		2	%
Asia and Others		34	%		27	%		40	%

We sell iodine through our own worldwide network of representative offices and through our sales, support and distribution affiliates. We maintain inventories of iodine at our facilities throughout the world to facilitate prompt delivery to customers. Iodine sales are made pursuant to spot purchase orders or within the framework of supply agreements. Supply agreements generally specify annual minimum and maximum purchase commitments, and prices are adjusted periodically, according to prevailing market prices.

Iodine: Competition

The world’s main iodine producers are based in Chile, Japan and the United States. Iodine is also produced in Russia, Turkmenistan, Azerbaijan, Indonesia and China.

Iodine is produced in Chile using a unique mineral known as caliche ore, whereas in Japan, the United States, Russia, Turkmenistan, Azerbaijan, and Indonesia, producers extract iodine from underground brines that are mainly obtained together with the extraction of natural gas and petroleum. In China, iodine is extracted from seaweed.

Five Chilean companies accounted for approximately 58% of total global sales of iodine in 2021, including SQM, with approximately 31%, and four other producers accounting for the remaining 27%. The other Chilean producers are Atacama Chemical S.A. (Cosayach), controlled by the Chilean holding company Inverraz S.A.; ACF Minera S.A., owned by the Chilean Urruticoechea family; Algorta Norte S.A., a joint venture between ACF Minera S.A. and Toyota Tsusho; and Atacama Minerals, which is owned by Chinese company Tewoo.

We estimate that eight Japanese iodine producers accounted for approximately 27% of global iodine sales in 2021, including recycled iodine.

We estimate that iodine producers in the United States accounted for nearly 5% of world iodine sales in 2021.

Iodine recycling is a growing trend worldwide. Several producers have recycling facilities where they recover iodine and iodine derivatives from iodine waste streams.

We estimate the 17% of the iodine supply comes from iodine recycling. Through ASG or alone, we are also actively participating in the iodine recycling business using iodinated side-streams from a variety of chemical processes in Europe and the United States.

34

The prices of iodine and iodine derivative products are determined by market conditions. World iodine prices vary depending upon, among other things, the relationship between supply and demand at any given time. Iodine supply varies primarily as a result of the production levels of the iodine producers (including us) and their respective business strategies. Our annual average iodine sales prices increased to approximately US$36 per kilogram in 2021, from the average sales prices of approximately US$35 per kilogram observed in 2020. During the first half of 2021, the price remained similar to 2020. However, in the second half of the year, the growth in demand and the challenging international logistics situation led to a gradual increase in prices.

Demand for iodine varies depending upon overall levels of economic activity and the level of demand in the medical, pharmaceutical, industrial and other sectors that are the main users of iodine and iodine-derivative products. Certain substitutes for iodine are available for certain applications, such as antiseptics and disinfectants, which could represent a cost-effective alternative to iodine depending on prevailing prices.

The main factors of competition in the sale of iodine and iodine derivative products are reliability, price, quality, customer service and the price and availability of substitutes. We believe we have competitive advantages compared to other producers due to the size and quality of our mining reserves and the available production capacity. We believe our iodine is competitive with that produced by other manufacturers in certain advanced industrial processes. We also believe we benefit competitively from the long-term relationships we have established with our largest customers.

Lithium and its Derivatives

In 2021, our revenues from lithium sales amounted to US$936.1 million, representing 32.7% of our total revenues. We believe we are one of the world’s largest producers of lithium carbonate and lithium hydroxide, and we estimate that our sales volumes accounted for approximately 19% of the global lithium chemicals sales volumes.

Lithium: Market

The lithium market can be divided into (i) lithium minerals for direct use (in which market SQM does not participate directly), (ii) basic lithium chemicals, which include lithium carbonate and lithium hydroxide (as well as lithium chloride, from which lithium carbonate may be made), and (iii) inorganic and organic lithium derivatives, which include numerous compounds produced from basic lithium chemicals (in which market SQM does not participate directly).

Lithium carbonate and lithium hydroxide are principally used to produce the cathodes for rechargeable batteries, taking advantage of lithium’s extreme electrochemical potential and low density. Batteries are the leading application for lithium, accounting for approximately 84% of total lithium demand, including batteries for electric vehicles, which accounted for approximately 70% of total lithium demand.

There are many other applications both for basic lithium chemicals and lithium derivatives, such as lubricating greases (approximately 4% of total lithium demand), heat-resistant glass (ceramic glass) (approximately 2% of total lithium demand), chips for the ceramics and glaze industry (approximately 1% of total lithium demand), chemicals for air conditioning (approximately 1% of total lithium demand), and many others, including pharmaceutical synthesis and metal alloys.

Lithium’s main properties, which facilitate its use in this range of applications, are that it:

· is the lightest solid metal and element at room temperature;

· is low density;

· has a low coefficient of thermal expansion;

· has high electrochemical potential; and

· has a high specific heat capacity.

35

During 2021, lithium chemicals demand increased by approximately 55%, reaching approximately 528,000 metric tons. We expect applications related to energy storage to continue driving demand in the coming years.

Lithium: Our Products

We produce lithium carbonate at our Carmen Lithium production facility, near Antofagasta, Chile, from highly concentrated lithium chloride produced in the Salar de Atacama. The annual production capacity of our lithium carbonate plant at the Carmen Lithium production facility is now 120,000 metric tons per year. We are in the process of increasing our production capacity to 180,000 metric tons per year. We believe that the technologies we use, together with the high concentrations of lithium and the characteristics of the Salar de Atacama, such as high evaporation rate and concentration of other minerals, allow us to be one of the lowest cost producers worldwide.

We also produce lithium hydroxide at the same plant at the Carmen Lithium production facility, next to the lithium carbonate operation. The lithium hydroxide facility has a production capacity of 21,500 metric tons per year and we are in the process of increasing this production capacity to 30,000 metric tons per year. In addition, in February 2021 our Board approved the investment for our 50% share of the development costs in the Mt. Holland lithium project in our joint venture with Wesfarmers, which we expect will have a total production capacity of 50,000 metric tons.

The following table shows our total sales volumes and revenues from lithium carbonate and its derivatives for 2021, 2020 and 2019:

	2021		2020		2019
Sales volumes (Th. MT)
Lithium and derivatives		101.1		64.6		45.1
Total revenues (in US$ millions)		936.1		383.4		505.7

Our revenues in 2021 were US$936.1 million, a 144.2% increase from US$383.4 million in 2020, due to higher average prices and higher sales volumes during the year. The average price for 2021 was approximately 56.1% higher than the average price in 2020.

Lithium: Marketing and Customers

In 2021, we sold our lithium products in approximately 43 countries to approximately 244 customers, and most of our sales were to customers outside of Chile. No customer accounted for more than 10% of our lithium revenues in 2021. Our ten largest customers accounted in the aggregate for approximately 44% of revenues. One supplier accounted for 10% of the cost of sales of this business line. We make lease payments to Corfo which are associated with the sale of different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. See Note 21.2 to our consolidated financial statements for the disclosure of lease payments made to Corfo for all periods presented.

Central and South America (excluding Chile)		1	%		0	%		1	%
Asia and Others		86	%		80	%		75	%

We sell lithium carbonate and lithium hydroxide through our own worldwide network of representative offices and through our sales, support and distribution affiliates. We maintain inventories of these products at our facilities throughout the world to facilitate prompt delivery to customers. Sales of lithium carbonate and lithium hydroxide are made pursuant to spot purchase orders or within the framework of supply agreements. Supply agreements generally specify annual minimum and maximum purchase commitments, and prices are adjusted periodically, according to prevailing market prices.

Lithium: Competition

Lithium is produced mainly from two sources: (i) concentrated brines and (ii) minerals. During 2021, the main lithium brines producers were Chile, Argentina and China, while the main lithium mineral producers were Australia and China. With total sales of approximately 101,000 metric tons of lithium carbonate and hydroxide, SQM’s market share of lithium chemicals was approximately 19% in 2021. One of our main competitors is Albemarle Corporation (“Albemarle”), which produces lithium carbonate and lithium chloride in Chile and the United States, along with lithium derivatives in the United States, Germany, Taiwan and China, with a lithium chemical market share of approximately 19%. Albemarle also owns 49% of Talison Lithium Pty Ltd. (“Talison”), an Australian company, that is the largest producer of concentrated lithium minerals in the world, based in Western Australia. The remaining 51% of Talison is owned by Tianqi Lithium Energy Australia Pty Ltd (“TLEA”), through a joint venture with the Chinese company Tianqi Lithium Corp. (“Tianqi”), with 51% of the ownership, and the Australian IGO Limited with the remaining 49%, producing basic lithium chemicals in China from concentrated lithium minerals. Talison sells a part of its concentrated lithium mineral production to the direct use market, but most of its production, representing approximately 14% of total lithium chemical demand, is converted into basic lithium chemicals in China by Tianqi and Albemarle. Currently, Tianqi and Albemarle are planning to begin production at their new lithium hydroxide plants in China and Australia, which are expected to be operational during 2022. Tianqi is also a significant shareholder of ours, holding approximately 23.13% of our shares as of March 1, 2022.

Another important competitor is Livent Corporation (“Livent”), with an estimated market share of approximately 4%. Livent has production facilities in Argentina through Minera del Altiplano S.A., where it produces lithium chloride and lithium carbonate. In addition, Livent produces lithium derivatives in the United States, the United Kingdom and China. Orocobre Ltd., based in Argentina, produces lithium carbonate, with a market share of approximately 2%.

Australia is an important source of concentrated lithium minerals. Since 2018, two producers have doubled their production of concentrated mineral, which is currently converted into lithium chemicals in China. One of these producers is a joint venture between Ganfeng Lithium Co. (“Ganfeng”) and Mineral Resources Ltd in the Mt. Marion project. Galaxy Resources Ltd. is another important producer with operations in Mt. Cattlin. Additionally, Pilbara Minerals has been operating since 2018 in the Pilgangoora deposit. In addition, there were at least ten other companies producing lithium in China from brines or minerals in 2021.

We believe that lithium production will continue to increase this decade, in response to an increase in demand growth. A number of new projects to develop lithium deposits has been announced recently. Some of these projects are already in the advanced stages of development and others could materialize in the medium term.

37

Potassium

In 2021, our potassium chloride and potassium sulfate revenues amounted to US$416.6 million, representing 14.6% of our total revenues and a 99.0% increase compared to 2020, as a result of increased average prices and higher sales volumes. We estimate that we accounted for approximately 1% of global sales of potassium chloride in 2021.

We produce potassium chloride by extracting brines from the Salar de Atacama that are rich in potassium chloride and other salts.

Potassium is one of the three macronutrients that a plant needs to develop. Although potassium does not form part of a plant’s structure, it is essential to the development of its basic functions. Potassium chloride is the most commonly used potassium-based fertilizer. It is used to fertilize crops that can tolerate relatively high levels of chloride, and to fertilize crops that are grown under conditions with sufficient rainfall or irrigation practices that prevent chloride from accumulating to excess levels in the rooting systems of the plant.

Some benefits that may be obtained through the use of potassium are:

· increased yield and quality;

· increased production of proteins;

· increased photosynthesis;

· intensified transport and storage of assimilates;

· prolonged and more intense assimilation period;

· improved water efficiency;

· regulated opening and closure of stomata; and

· synthesis of lycopene.

Potassium chloride is also an important component for our specialty plant nutrition product line, where it is used as a raw material to produce potassium nitrate.

Since 2009, our effective end product capacity has increased to over 2 million metric tons per year, granting us improved flexibility and market coverage.

Potassium: Market

During the last decade, growth in demand for potassium chloride, and for fertilizers in general, has been driven by several key factors, such as a growing world population, higher demand for protein-based diets and less arable land. All of these factors contribute to fertilizer demand growth as a result of efforts to maximize crop yields and use resources more efficiently. For the last ten years, the compound annual growth for the global potassium chloride market was approximately 2 to 3%. We estimate that demand in 2021 reached approximately 71 million metric tons.

According to studies prepared by the International Fertilizer Industry Association, cereals account for approximately 45% of world potassium consumption, including corn (14%), rice (13%) and wheat (3%). Oilseeds, predominantly soybeans and palm oil, represent approximately 16% of total potassium demand. Fruits and vegetables account for approximately 22% of world potassium demand, and sugar crops account for close to 7%.

Potassium: Our Products

Potassium chloride differs from our specialty plant nutrition products because it is a commodity fertilizer and contains chloride. We offer potassium chloride in two grades: standard and compacted. Potassium sulfate is considered a specialty fertilizer and we offer this product in soluble grades.

38

The following table shows our sales volumes of and revenues from potassium chloride and potassium sulfate for 2021, 2020 and 2019:

	2021		2020		2019
Sales volumes (Th. MT)
Potassium chloride and potassium sulfate		893.2		726.7		597.3
Total revenues (in US$ millions)		416.6		209.3		212.2

Our revenues in 2021 were US$416.6 million, a 99.0% increase from US$209.3 million in 2020, due to significantly higher prices and higher sales volumes during the year. Our sales volumes in 2021 were approximately 22.9% higher than sales volumes reported during 2020.

Potassium: Marketing and Customers

In 2021, we sold potassium chloride and potassium sulfate to approximately 543 customers in approximately 38 countries. One individual customer accounted for more than 10% of our revenues of potassium chloride and potassium sulfate in 2021, representing approximately 13% of our revenues in the business line. We estimate that our ten largest customers accounted in the aggregate for approximately 46% of such revenues. One supplier accounted for more than 10% of the cost of sales of this business line, accounting for approximately 11% of the cost of sales for the business line. We make lease payments to Corfo which are associated with the sale of different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. See Note 21.2 to our consolidated financial statements for the disclosure of lease payments made to Corfo for all periods presented.

The following table shows the geographical breakdown of our revenues:

Revenues breakdown	2021			2020			2019
North America		14	%		19	%		20	%

Central and South America (excluding Chile)		51	%		35	%		31	%
Asia and Others		14	%		21	%		23	%

Potassium: Competition

We estimate that we accounted for approximately 1% of global sales of potassium chloride in 2021. Our main competitors are Nutrien, Uralkali, Belaruskali and Mosaic. We estimate that in 2021, Nutrien accounted for approximately 19% of global sales, Belaruskali accounted for approximately 18% of global sales, Uralkali accounted for approximately 18% of global sales, and Mosaic accounted for approximately 13% of global sales.

Industrial Chemicals

In 2021, our revenues from industrial chemicals were US$132.0 million, representing approximately 4.6% of our total revenues for that year.

In addition to producing sodium and potassium nitrate for agricultural applications, we produce different grades of these products, including prilled grades, for industrial applications. The grades differ mainly in their chemical purity. We enjoy certain operational flexibility producing industrial nitrates, because they are produced from the same process as their equivalent agricultural grades, needing only an additional step of purification. We may, with certain constraints, shift production from one grade to the other depending on market conditions. This flexibility allows us to maximize yields and to reduce commercial risk.

39

In addition to producing industrial nitrates, we produce, market and sell industrial-grade potassium chloride.

Industrial Chemicals: Market

Industrial sodium and potassium nitrates are used in a wide range of industrial applications, including the production of glass, ceramics and explosives, metal recycling, insulation materials, metal treatments, thermal solar and various chemical processes.

In addition, this product line has also experienced growth from the use of industrial sodium and potassium nitrates as thermal storage in concentrated solar power plants (commonly known as “CSP”). Solar salts contain a blend of 60% sodium nitrate and 40% potassium nitrate by weight ratio and are used as a storage and heat transfer medium. Unlike traditional photovoltaic plants, these new plants use a “thermal battery” that contains molten sodium nitrate and potassium nitrate, which store the heat collected during the day. The salts are heated up during the day, while the plants are operating under direct sunlight, and at night they release the solar energy that they have captured, allowing the plants to operate even during hours of darkness. Depending on the power plant technology, solar salts are also used as a heat transfer fluid in the plant system and thereby make CSP plants even more efficient, increasing their output and reducing the Levelized Cost of Electricity (LCOE).

We see a growing trend for the CSP application as a result of its economic value in the need to develop long duration electricity storage worldwide. Thermal storage using solar salts are also being developed in “Carnot Batteries”. These batteries are charged with thermal energy recovered by other renewable sources like PV and wind, through electrical heaters. These systems represent an excellent solution for achieving global decarbonization targets defined around the world and can be deployed in locations where other technologies are not physically or economically viable, to provide long duration energy storage. The thermal storage of CSP plants helps to improve the stabilization of the electricity grid. Like all large power generation plants, such large CSP power plants are capital intensive and require a relatively long development period.

We supply solar salts to CSP projects around the world. In 2021, we sold approximately 100,000 metric tons of solar salts to supply a CSP project in the Middle East. We expect to supply over 400,000 metric tons to this project between 2020-2022. In addition, there are several major solar salt and Carnot Battery projects currently under development worldwide that we believe we could supply between 2022-2025.

We are also experiencing a growing interest in using solar salts in thermal storage solutions not related to CSP technology. Due to their proven performance, solar salts are being tested in industrial heat processes and heat waste solutions. These new applications may open new opportunities for solar salts uses in the near future, such as retrofitting coal plants.

Industrial Chemicals: Our Products

The following table shows our sales volumes of industrial chemicals and total revenues for 2021, 2020 and 2019:

	2021		2020		2019
Sales volumes (Th. MT)
Industrial chemicals		174.5		225.1		123.5
Total revenues (in US$ millions)		132.0		160.6		94.9

Revenues for industrial chemicals decreased to US$132.0 million in 2021 from US$160.6 million in 2020, as a result of lower sales volumes in this business line. Sales volumes in 2021 decreased 22.5% compared to sales volumes reported last year.

Industrial Chemicals: Marketing and Customers

We sold our industrial nitrate products in approximately 59 countries in 2021 to approximately 280 customers. One customer accounted for more than 10% of our revenues of industrial chemicals in 2021, accounting for approximately 51%, and our ten largest customers accounted in the aggregate for approximately 66% of such revenues. No supplier accounted for more than 10% of the cost of sales of this business line. We make lease payments to Corfo which are associated with the sale of different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. See Note 21.2 to our consolidated financial statements for the disclosure of lease payments made to Corfo for all periods presented.

The following table shows the geographical breakdown of our revenues for 2021, 2020 and 2019:

Revenues breakdown	2021			2020			2019
North America		23	%		15	%		29	%
Europe		14	%		7	%		16	%

Central and South America (excluding Chile)		6	%		3	%		7	%
Asia and Others		55	%		72	%		6	%

Our industrial chemical products are marketed mainly through our own network of offices, representatives and distributors. We maintain updated inventories of our stocks of sodium nitrate and potassium nitrate, classified according to graduation, to facilitate prompt dispatch from our warehouses. We provide support to our customers and continuously work with them to develop new products and applications for our products.

Industrial Chemicals: Competition

We believe that we are one of the world's largest producers of industrial sodium nitrate and potassium nitrate. In 2021, our estimated market share by volume for industrial potassium nitrate was 71% and for industrial sodium nitrate was 43% (excluding domestic demand in China and India).

Our competitors in sodium nitrate are mainly based in Europe and Asia, producing sodium nitrate as a by-product of other production processes. In sodium nitrate, BASF AG, a German corporation, and several producers in Eastern Europe and China are competitive since they produce industrial sodium nitrate as a by-product. Our industrial sodium nitrate grades also compete indirectly with substitute chemicals, including sodium carbonate, sodium sulfate, calcium nitrate and ammonium nitrate, which may be used in certain applications instead of sodium nitrate and are available from a large number of producers worldwide.

Our main competitors in the industrial potassium nitrate business are Haifa Chemicals, Kemapco and some Chinese producers, which we estimate had a market share of 6%, 5% and 4%, respectively, in 2021. We estimate that our market share was approximately 71% for 2021.

41

Producers of industrial sodium nitrate and industrial potassium nitrate compete in the marketplace based on attributes such as product quality, delivery reliability, price, and customer service. Our operation offers both products at high quality and with low cost. In addition, our operation is flexible, allowing us to produce industrial or agricultural nitrates, maximizing our yields and reducing commercial risk. In addition, with certain restrictions, we are able to adapt production from one grade to another depending on market needs.

In the potassium chloride market, we are a relatively small producer, mainly focused on supplying regional needs.

Other Products

SQM also receives income from the commercialization of third-party fertilizers (specialty and commodity). These fertilizers are traded in large volumes worldwide and are used as raw material for our specialty mixes or to complement our product portfolio. We have developed commercial management, supply, flexibility and inventory management capabilities that allow us to adapt to the changing fertilizer market in which we operate and obtain profits from these transactions.

Production Process

Our integrated production process can be classified according to our natural resources:

· caliche ore deposits, which contain nitrates, iodine and potassium; and

· brines from the Salar de Atacama, which contain potassium, lithium, sulfate, boron and magnesium.

Caliche Ore Deposits

Caliche ore deposits are located in the First and Second Regions in northern Chile. During 2021, our mining operations concentrated in the First Region where we mainly worked in the mining sector Tente en el Aire and in the mining sectors Nueva Victoria Oeste, Norte and Torcaza. The Second Region mining operations at the Pampa Blanca site, the El Toco mine (which is part of the María Elena site) and the Pedro de Valdivia site were suspended in March 2010, November 2013 and November 2015, respectively, in an effort to optimize our production facilities with lower production costs.

Caliche ore is found under a layer of barren overburden in seams with variable thickness from twenty centimeters to four meters, and with the overburden varying in thickness between half a meter and two meters.

Before proper mining begins, the exploration stage is carried out, including complete geological reconnaissance, sampling and drilling caliche ore to determine the quality and characteristics of each deposit and treatability tests are performed at a pilot plant. Drill-hole samples are properly identified and tested at our chemical laboratories. With the exploration information on a closed grid pattern of drill holes, the ore evaluation stage provides information for mine planning purposes. Mine planning is done on a long-term basis (ten years), medium-term basis (three to five years) and short-term basis (one year). Once all of this information has been compiled, detailed planning for the exploitation of the mine takes place.

The mining process generally begins with bulldozers first removing the overburden in the mining area. This process is followed by an inspection and review of the drill holes before production drilling and blasting occurs to break the caliche seams. Front-end loaders and bulldozers load the ore onto off-road trucks, which take it to the leaching heaps to be processed.

42

During 2021, SQM worked with two continuous mining equipment systems to replace the drilling and blasting process for mining some of the caliche ore and obtaining a smaller ore size (under 6 ½ inches) that allows a better metallurgical recovery.

The run of mine ore is loaded in heaps and leached with water to produce concentrated solutions containing iodine, nitrate and potassium. These solutions are then sent to plants where iodine is extracted through both solvent-extraction and blow out processes. The remaining solutions are subsequently sent to solar evaporation ponds where the solutions are evaporated and salts rich in nitrate and potassium are produced. These concentrated salts are then sent to Coya Sur where they are used to produce potassium nitrate and sodium nitrate.

During 2021, the Pedro de Valdivia site generated solutions produced by leaching the mine tailings. These solutions are treated at the iodide plant at Pedro de Valdivia. After iodide is obtained, the remaining solutions, which are rich in nitrate and potassium, are sent to the solar evaporation ponds at Coya Sur in order to be used in the production of potassium nitrate.

Caliche Ore-Derived Products

Caliche ore-derived products are sodium nitrate, potassium nitrate, sodium potassium nitrate and iodine.

Sodium Nitrate

During 2021, sodium nitrate for both agricultural and industrial applications was produced from nitrate salts from our mining operations at Sur Viejo and fed to our new crystallization plant located in Coya Sur. Crystallized sodium nitrate is processed at the Coya Sur production plants to produce sodium nitrate and sodium potassium nitrate in different chemical and physical forms, including crystallized and prilled products. Finally, the products are transported by truck to our port facilities in Tocopilla for shipping to customers and distributors worldwide.

Potassium Nitrate

Potassium nitrate is produced at our Coya Sur facility using a production process developed in-house. The brines generated by the leaching process at Pedro de Valdivia are pumped to Coya Sur’s solar evaporation ponds for a nitrate concentration process. After the nitrate concentration process, the brine is pumped to a conversion plant where potassium salts from the Salar de Atacama and nitrate and potassium salts produced at Nueva Victoria or Coya Sur are added. A chemical reaction begins, transforming sodium nitrate into potassium nitrate and discarding formed sodium chloride. Depending on the specifications of the required product, it is subjected to an adiabatic or atmospheric cooling process to obtain the required quality.

Our current potassium nitrate production capacity at Coya Sur is approximately 1,300,000 metric tons per year. During 2021, we worked on several initiatives to improve productivity, including the commencement of the construction of a new magnesium abatement plant in Sur Viejo which will allow for high content potassium nitrate salt recovery from potassium salts from the Salar de Atacama. This plant will begin the commissioning process in the first half of 2022. We also began the removal of magnesium in nitrates from Pedro de Valdivia by using high sulfate salts from Pampa Blanca that allow for improved nitrate recovery during the evaporation ponds process.

The potassium nitrate produced at Coya Sur is transported to Tocopilla for shipping and delivery to customers and distributors. All potassium nitrate produced in crystallized or prilled form at Coya Sur has been certified by TÜV-Rheinland under the quality standard ISO 9001:2015.

43

Sodium Potassium Nitrate

Sodium potassium nitrate is a mixture of approximately two parts sodium nitrate per one part potassium nitrate. We produce sodium potassium nitrate at our Coya Sur prilling facilities using standard, non-patented production methods we have developed. Crystallized sodium nitrate is supplied together with the crystallized potassium nitrate to the prilling plant where it is mixed producing sodium potassium nitrate, which is then melted and prilled. The prilled sodium potassium nitrate is transported to Tocopilla for bulk shipment to customers.

The production process for sodium potassium nitrate is basically the same as that for sodium nitrate and potassium nitrate. With certain production restraints and following market conditions, we may supply sodium nitrate, potassium nitrate or sodium potassium nitrate, either in prilled or crystallized form.

The sodium potassium nitrate produced at Coya Sur is transported to Tocopilla for shipping and delivery to customers and distributors.

Iodine and Iodine Derivatives

During 2021, we produced iodine at our facilities at Nueva Victoria (including the Iris facility) and Pedro de Valdivia.Iodine is extracted from solutions produced by leaching caliche ore.

As in the case of nitrates, the process of extracting iodine from the caliche ore is well established, but variations in the iodine and other chemical contents of the treated ore and other operating parameters require a high level of know-how to manage the process effectively and efficiently.

The solutions resulting from the leaching of caliche ore carry iodine in iodate form. Part of the iodate solution is reduced to iodide using sulfur dioxide, which is produced by combusting (burning) sulfur. The resulting iodide is combined with the rest of the untreated iodate solution to release elemental iodine in low concentrations. The iodine is then extracted from the aqueous solutions and concentrated in iodide form using a solvent extraction and stripping plant in the Pedro de Valdivia and Nueva Victoria facilities and using a blow out plant in the Iris facility. The concentrated iodide is oxidized to metallic iodine, which is then refined through a smelting process and prilled. We have obtained patents in the United States and Chile (Chilean patent number 47,080) for our iodine prilling process.

Prilled iodine is tested for quality control purposes, using international standard procedures that we have implemented. It is then packed in 20 to 50-kilogram drums or 350-to-700-kilogram maxi bags and transported by truck to Antofagasta, Mejillones, or Iquique for export. Our iodine and iodine derivatives production facilities have qualified under the ISO 9001:2015 program, providing third-party certification—by TÜV-Rheinland—of the quality management system. The last recertification process was approved in November 2020, valid through 2023.

Our total iodine production in 2021 was 10,225 metric tons: 7,954 metric tons from Nueva Victoria, 795 metric tons from Iris, and 1,506 metric tons from Pedro de Valdivia. Nueva Victoria is also equipped to toll iodine from iodide delivered from our other facilities. We have the flexibility to adjust our production according to market conditions. Following the production facility restructuring at Pedro de Valdivia and Nueva Victoria, along with the ramp-up of our new iodide plant in Nueva Victoria, our total current production capacity at our iodine production plants is approximately 16,000 metric tons per year, this considers efficiency projects at the Nueva Victoria prilling plant, which now has a total capacity of 11,000 metric tons, and at our plant in Pedro de Valdivia, with a total capacity of 5,000 metric tons. Currently, all the finished iodine is produced in Nueva Victoria, since production at the Pedro de Valdivia plant has been suspended since November 2021 and will be restarted as more iodine production capacity is needed.

In November 2021, the Tarapacá Environmental Assessment Commission environmentally authorized the Tente en el Aire project, which allows the productive capacities of the Nueva Victoria Faena facility to be increased, incorporating seawater for its processes. This project expects to incorporate the use of 900 liters per second of seawater, increasing the mine area and allowing for increased production of iodine and nitrate salts.

In parallel, work is being done on the new Pampa Orcoma project in the Tarapacá Region. This has an approved RCA for 2,500 tons of iodine per year and 320,000 tons of nitrate-rich salts per year, in addition to the use of 200 l/s of seawater for the leaching operation. Currently, progress is being made with the processing of the necessary permits for its exploitation. Production operation is expected to start during 2024.

We use a portion of the iodine we produce to manufacture inorganic iodine derivatives, which are intermediate products used for manufacturing agricultural and nutritional applications, at facilities located near Santiago, Chile. We also produce inorganic and organic iodine derivative products together with Ajay, which purchases iodine from us. In the past, we have primarily sold our iodine derivative products in South America, Africa and Asia, while Ajay and its affiliates have primarily sold their iodine derivative products in North America and Europe.

Salar de Atacama Brine Deposits

The Salar de Atacama, located approximately 210 kilometers east of Antofagasta, is a salt-encrusted depression in the Atacama Desert, within which lies an underground deposit of brines contained in porous sodium chloride rock fed by an underground inflow from the Andes mountains, which is the result of millions of years of climatic and tectonic impacts. Brines are pumped from depths of 15 to 150 meters below surface, through a field of wells that are located in the Salar de Atacama, distributed in areas authorized for exploitation, and which contain relatively high concentrations of potassium, lithium, sulfates and other minerals.

The brines are estimated to cover a surface of approximately 2,800 square kilometers and contain commercially exploitable deposits of potassium, lithium, sulfates and boron. Concentrations vary at different locations throughout the Salar de Atacama. Our mining exploitation rights to the Salar de Atacama are pursuant to the Lease Agreement, which expires in 2030. The Lease Agreement, as amended in January 2018, permits the CCHEN to establish a total accumulated production and sales limit of up to 349,553 metric tons of lithium metallic equivalent (1,860,671 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount. See “Item 3.D. Risk Factors” and “Item 8.A.7 Legal Proceedings.”

For the year ended December 31, 2021, revenues related to products originating from the Salar de Atacama represented 47% of our consolidated revenues, consisting of revenues from our potassium business line and our lithium and derivatives business line for the period. All of our products originating from the Salar de Atacama are derived from our extraction operations under the Lease Agreement. As of December 31, 2021, only 9 years remain on the term of the Lease Agreement.

Products Derived from the Salar de Atacama Brines

The products derived from the Salar de Atacama brines are potassium chloride, potassium salts, lithium chloride solutions, lithium carbonate, lithium hydroxide, lithium salts, potassium sulfate, boric acid, sodium chloride and bischofite (magnesium chloride).

Potassium Chloride

We use potassium chloride in the production of potassium nitrate. Production of our own supplies of potassium chloride provides us with substantial raw material cost savings. We also sell potassium chloride to third parties, primarily as a commodity fertilizer.

45

In order to produce potassium chloride, brines from the Salar de Atacama are pumped to solar evaporation ponds. Evaporation of the water contained in the brine, results in a crystallized mixture of salts with various content levels of potassium, sodium and magnesium. In the first stage of the evaporation process, sodium chloride salts (halite) precipitate, they are then harvested and removed; these salts have the potential to be used in the copper mining process. In the second stage of the evaporation process, the remaining brine from the first stage is transferred to other evaporation ponds where potassium chloride salts together with sodium chloride (sylvinite) precipitate, these salts are harvested and then sent for treatment at one of the wet potassium chloride plants where potassium chloride is separated by a grinding, flotation, and filtering process. In the final evaporation stage, salts containing magnesium are harvested and eventually can be treated at one of the cold leach plants where magnesium is removed. Part of the potassium chloride is transported approximately 300 kilometers to our Coya Sur facilities via a dedicated truck transport system, where it is used in the production of potassium nitrate. The use of potassium chloride salts as a raw material in Coya Sur allows us to capture significant savings, as it allows us to use potassium salts with different qualities and to avoid buying and importing potassium chloride from external sources.

The remainder of the potassium chloride produced at the Salar de Atacama is shipped to our port in Tocopilla in either crystalized (standard) or granular (compacted) form and then shipped and sold as a commodity fertilizer to third parties. All of our potassium chloride-related plants in the Salar de Atacama currently have a nominal production capacity of up to 2.6 million metric tons per year. Actual production capacity depends on volume, quality and performance of the salts used in the process and quality of the mining resources pumped from the Salar de Atacama.

The brine that remain in the evaporation pond system after removal of the sodium chloride and potassium chloride generates a concentrated lithium chloride solution, which is used to produce lithium carbonate (as described below) and generates salts rich in magnesium chloride (bischfite) as a by-product.

Lithium Chloride Solution and Lithium Carbonate

After the production and precipitation of the potassium chloride salts, a portion of the solutions remaining is sent to additional solar evaporation ponds adjacent to the potassium evaporation ponds. At this stage, the solution is purified and concentrated by precipitation to remove impurities it may still contain, including calcium, sulfate, potassium, sodium and magnesium, reaching a lithium concentration level of approximately 5-6%. Next is the process of concentration and purification of the remaining concentrated solution of lithium chloride, which is transported by truck to the Carmen Lithium production facilities located near Antofagasta, approximately 190 kilometers southeast of the Salar de Atacama. At this plant, the solution is further purified and treated with sodium carbonate to produce lithium carbonate, which is dried and then, if necessary, compacted and finally packaged for shipment to customers.

The production capacity of our lithium carbonate facility since the end of 2021 has been 120,000 metric tons per year. We are now expanding lithium carbonate capacity to reach 180,000 metric tons per year during 2022.

Future production will depend on the actual volumes and quality of the lithium solutions sent by the Salar de Atacama operations, as well as prevailing market conditions. Our future production will also be subject to the extraction limit described in the Lease Agreement mentioned above. See “—Salar de Atacama Brine Deposits” and “Item 8.A.7 Legal Proceedings.”

Our lithium carbonate production quality assurance program has been certified by TÜV-Rheinland under ISO 9001:2015 since September 2018.

46

Lithium Hydroxide

Lithium carbonate is sold to customers, and we also use it as a raw material for our lithium hydroxide production, which started operations at the end of 2005. We currently have three lithium hydroxide plants, one of which entered into operations at the end of March 2022, and have a total production capacity of 21,500 metric tons per year. These plants are located at the Carmen Lithium production facility, adjacent to our lithium carbonate operations.

In the production process, lithium carbonate is reacted with a lime solution to produce lithium hydroxide brine and calcium carbonate salt. The calcium carbonate salt is removed from the process by filtration and the lithium hydroxide brine is stored in ponds. The brine is then evaporated in a multi-effect evaporator and crystallized to produce lithium hydroxide which is then dried and packaged for shipment to customers.

Our lithium hydroxide production quality assurance program has been certified by TÜV-Rheinland under

ISO 9001:2015 since September 2018.

Potassium Sulfate and Boric Acid

Approximately 12 kilometers northeast of the potassium chloride facilities at the Salar de Atacama, we use the brines from the Salar de Atacama to produce potassium sulfate, potassium chloride (as a by-product of the potassium sulfate process) and, depending on market conditions, boric acid. The plant is located in an area of the Salar de Atacama where high sulfate and potassium concentrations are found in the brines to produce potassium sulfate. The brine is pumped to solar evaporation ponds, where sodium chloride salts are precipitated, harvested and put into piles. After further evaporation, the sulfate and potassium salts precipitate in different concentrations and are harvested and sent for processing to the potassium sulfate plant. Potassium sulfate is produced using flotation, concentration and reaction processes, after which it is crystallized, filtered, dried, classified and packaged for shipment.

Production capacity for the potassium sulfate plant is approximately 340,000 metric tons per year, of which approximately 95,000 metric tons correspond to potassium chloride obtained as a by-product of this process. This capacity is part of the total nominal plant capacity of 2.6 million metric tons per year. In our dual plant complex, we may switch, to some extent, between potassium chloride and potassium sulfate production. Part of the pond system in this area is also used to process potassium chloride brines extracted from the low sulfate concentration areas found in the Salar de Atacama. Depending on the conditions for the optimization of the deposit operation and/or market conditions, potassium sulfate production can be modified to produce potassium chloride. 

The principal by-products of the production of potassium sulfate are: (i) non-commercial sodium chloride, which is deposited at sites near the production facility and (ii) remaining solutions, which are re-injected into the Salar de Atacama or returned to the evaporation ponds. The principal by-products of the boric acid production process are remaining solutions that are treated with sodium carbonate to neutralize acidity and then are reinjected into the Salar de Atacama.

Raw Materials

The main raw material that we require in the production of nitrate and iodine is caliche ore, which is obtained from our surface mines. The main raw material in the production of potassium chloride, lithium carbonate, lithium hydroxide and potassium sulfate is the brine extracted from our operations at the Salar de Atacama.

Other important raw materials are sodium carbonate (used for lithium carbonate production), calcium oxide, sulphuric acid, hydrochloric acid, kerosene, sulphur, anti-caking and anti-dust agents, calcium oxide, potassium carbonate, ammonium nitrate (used for the preparation of explosives in the mining operations), woven bags for packaging our final products, electricity acquired from electric utilities companies, and liquefied natural gas and fuel oil for heat generation. Our raw material costs (excluding caliche ore and salar brines and including energy) represented approximately 15% of our cost of sales in 2021.

47

Since 2017, we have been connected to the central grid, which supplies electricity to the majority of cities and industries in Chile.

We have several electricity supply agreements signed with major producers in Chile, which are within the contract terms.

Our electricity needs are primarily covered by the Electrical Energy Supply Agreement that we entered into with AES Gener S.A. on December 31, 2012.

For our supply of liquefied natural gas, we maintain a five-year contract with Engie, which was executed in 2019 and some annual contracts to supply possible increases in demand In addition, we have a supply of liquefied petroleum gas (LPG) from Lipigas at the Carmen Lithium production facility and the Salar de Atacama.

We obtain ammonium nitrate, sulphuric acid, hydrochloric acid, kerosene, sulphur, calcium oxide and soda ash from several large suppliers, mainly in Chile,the United States and Europe, under long-term contracts or general agreements, some of which contain provisions for annual revisions of prices, quantities and deliveries. Diesel fuel is obtained under contracts that provide fuel at international market prices.

We believe that all of our contracts and agreements with third-party suppliers with respect to our main raw materials contain standard and customary commercial terms and conditions.

Water Supply

We hold water rights for the supply of surface and subterranean water near our production facilities. The main sources of water for our nitrate and iodine facilities at Pedro de Valdivia, María Elena and Coya Sur are the Loa and San Salvador rivers, which run near our production facilities. Water for our Nueva Victoria and Salar de Atacama facilities is obtained from wells near the production facilities. In addition, we buy water from third parties for our lithium carbonate and lithium hydroxide production processes at the Carmen Lithium production facility, and we also purchase potable water from local utility companies. We have not experienced significant difficulties obtaining the necessary water to conduct our operations.

Government Regulations

Regulations in Chile Generally

We are subject to the full range of government regulations and supervision generally applicable to companies engaged in business in Chile, including labor laws, social security laws, public health laws, consumer protection laws, tax laws, environmental laws, free competition laws, and securities laws. These include regulations to ensure sanitary and safety conditions in manufacturing plants.

We conduct our mining operations pursuant to judicial exploration concessions and exploitation concessions granted pursuant to applicable Chilean law. Exploitation concessions essentially grant a perpetual right (with the exception of the Salar de Atacama rights, which have been leased to us until 2030) to conduct mining operations in the areas covered by such concessions, provided that annual concession fees are paid. Exploration concessions permit us to explore for mineral resources on the land covered thereby for a specified period of time, and to subsequently request a corresponding exploitation concession.

Under Law No. 16,319 that created the Chilean Nuclear Energy Commission (

Comisión Chilena de Energía Nuclear

), or “CCHEN”, we have an obligation to the CCHEN regarding the exploitation and sale of lithium from the Salar de Atacama, which prohibits the use of lithium for nuclear fusion. In addition, CCHEN has imposed quotas that limit the total tonnage of lithium authorized to be sold, along with other conditions.

48

We also hold water use rights granted by the respective administrative authorities and which enable us to have a supply of water from rivers or wells near our production facilities sufficient to meet our current operating requirements. See “Item 3.D. Risk Factors—Risks Relating to Chile—Changes to the Chilean Constitution could impact a wide range of rights, including mining rights, water rights and property rights generally, and could affect our business, results of operations and financial condition.” and “—Changes in water rights laws and other regulations could affect our operating costs.” The Chilean Constitution, the Water Code and related regulations are subject to change, which could have a material adverse impact on our business, financial condition and results of operations.

We operate port facilities at Tocopilla, Chile for the shipment of products and the delivery of raw materials in conformity with maritime concessions, which have been granted by the respective administrative authority. These concessions are normally renewable on application, provided that such facilities are used as authorized and annual concession fees are paid.

In 2005, Law No. 20,026, known as the “Law to Establish a Specific Tax on Mining Activity” (Ley que Establece un Impuesto Específico a la Actividad Minera) or the “Royalty Law”, established a tax to be applied to mining activities developed in Chile. In 2010, modifications were made to the law and taxes were increased.

On February 24, 2020, Law No.21,210 the “Law to Modernize the Tax Legislation” was published. As a result of these reforms, open stock corporations, such as SQM, are subject to the general rules. The corporate tax rate that applies to us increased to 27% in 2018.

The Chilean government may again decide to levy additional taxes on mining companies or other corporations in Chile, and such taxes could have a material adverse impact on our business, financial condition and results of operations.

We are also subject to the Chilean Labor Code and the Subcontracting Law, which are overseen by the Labor Authority (

Dirección del Trabajo),

the National Geology and Mining Service (

Servicio Nacional de Geología y Minería

or “Sernageomin”), and the National Health Service. Recent changes to these laws and their application may have a material adverse effect on our business, financial condition and results of operations. See “Item 3.D. Risk Factors—Risks Relating to Our Business—We are exposed to labor strikes and labor liabilities that could impact our production levels and costs.”

In addition, we are subject to Law No. 20,393, which establishes criminal liability for legal entities, for the crimes of (a) asset laundering, (b) financing terrorism and (c) bribery. Potential sanctions for violations under this law could include (i) fines, (ii) loss of certain governmental benefits during a given period, (iii) a temporary or permanent bar against the corporation executing contracts with governmental entities, and (iv) dissolution of corporation.

We are subject to the Securities Law and Law No. 18,046 on Corporations (

Ley de Sociedades Anónimas

or the “Chilean Corporations Act”), which regulates corporate governance of public companies. Specifically, the Chilean Corporations Act regulates, among other things, independent director requirements, disclosure obligations to the general public and to the CMF, as well as regulations relating to the use of inside information, the independence of external auditors, and procedures for the analysis of transactions with related parties. See “Item 6.C. Board Practices” and “Item 7.B. Related Party Transactions.”

49

On March 2, 2021, the Chilean Congress approved a bill to strengthen the financial market in Chile, which includes, among others, the following provisions: (a) Amends Law No. 18,045 (the Securities Market Law), mainly in the following matters: (i) a prohibition was established for directors, managers, administrators and principal executives of an issuer of publicly offered securities, as well as their relatives, to carry out transactions on securities issued by the issuer, within thirty days prior to the disclosure of the latter’s quarterly or annual financial statements; (ii) increased certain penalties and modified, expanded and added criminalized conducts; and (iii) established that the information provided to investors or the general public containing recommendations to acquire, maintain or dispose of publicly offered securities, or that implies the definition of target prices, must comply with the requirements established by the CMF; (b) Amends  the Chilean Corporations Act, mainly in the following matters: (i) it adds, as a presumption of guilt of directors, the approval of related party transactions in contravention of the applicable rules; (ii) it modifies rules applicable to independent directors and the directors' committee; and (iii) it modifies the rules for approval of related party transactions for open corporations; (c) Amends DL 3,538 (CMF), mainly in the following matters: (i) penalties for audited persons are increased, from a ceiling of UF 15,000 to UF 100,000, in both cases, with the possibility of increasing it five times in case of recidivism; and (ii) the figure of the “Anonymous Whistleblower” is created for collaboration with investigations; (e) Amends the Commercial Code, mainly in insurance matters; (f) Amends Law No. 18,010 (Money Lending Transactions), mainly in the following matters: (i) establishes that default interest may not be applied jointly or additionally, on the same amount, with any other interest and its capitalization is prohibited; and (ii) establishes that the entities supervised by the CMF, including massive fund placement entities, may charge commissions with respect to money credit operations to the extent that such commissions comply with the requirements, rules and conditions established by the CMF through General Rule and, in any case, to the extent that they correspond to consideration for real and effectively rendered services.

There are currently no material legal or administrative proceedings pending against us except as discussed under “Item 8.A.7 Legal Proceedings”, in Note 20 to our Consolidated Financial Statements and below under “Safety, Health and Environmental Regulations in Chile.”

Safety, Health and Environmental Regulations in Chile

Our operations in Chile are subject to both national and local regulations related to safety, health and environmental protection. In Chile, the main regulations on these matters that are applicable to us are the Mine Health and Safety Act of 1989 (Reglamento de Seguridad Minera or the “Mine Health and Safety Act”), the Health Code (Código Sanitario), the Health and Basic Conditions Act of 1999 (Reglamento sobre Condiciones Sanitarias y Ambientales Básicas en los Lugares de Trabajo or the “Health and Basic Conditions Act”), the Subcontracting Law, the Environmental Law of 1994, amended in 2010 (Ley sobre Bases Generales del Medio Ambiente or the “Environmental Law”) and Law No.16,744 of the Labor Code relating to workplace accidents and occupational diseases (“Law No. 16,744”).

Health and safety at work are fundamental aspects in the management of mining operations, which is why we have made constant efforts to maintain good health and safety conditions for the people working at our mining sites and facilities. In addition to the role played by us in this important matter, the Chilean government has a regulatory role, enacting and enforcing regulations in order to protect and ensure the health and safety of workers. The Chilean government, acting through the Ministry of Labor and Social Security, Ministry of Health, and the Sernageomin, performs health and safety inspections at the mining sites and oversees mining projects, among other tasks, and it has exclusive powers to enforce standards related to environmental conditions and the health and safety of the people performing activities related to mining.

The regulations set in Law No. 16744 and the Mine Health and Safety Act protect workers and nearby communities from health and safety hazards. The Health and Basic Conditions Act along with our Internal Mining Standards (

Reglamentos Internos Mineros

) establish guidelines to maintain a workplace where safety and health risks are managed appropriately. We are subject to the general provisions of the Health and Basic Conditions Act, our own internal standards and the provisions of the Mine Health and Safety Act. In the event of non-compliance, the Ministry of Health and relevant regulatory bodies are entitled to use their enforcement powers to ensure compliance with the law.

50

In November 2011, the Ministry of Mining enacted Law No. 20,551 that Regulates the Closure of Mining Sites and Facilities (

Ley que Regula el Cierre de Faenas e Instalaciones Mineras

).  This statute entered in force in November 2012 and required all mining sites to present or update their closure plans as of November 2014. SQM has fulfilled this requirement for all of its mining sites and facilities. The main requirements of the law are related to disclosures to the Sernageomin regarding decommissioning plans for each mining site and its facilities, along with the estimated cost to implement such plans. The mining site closure plans are approved by Sernageomin and the corresponding financial assurances are subject to approval by the CMF. In both cases, SQM has received the requisite approvals. During 2020, any required closure plans were updated and presented to Sernageomin in accordance with required deadlines and in 2021, we continued this process as required by formal comments we have received.

The new and modified Chilean Environmental Law defines the Ministry of the Environment as the governmental agency responsible for coordinating and supervising environmental issues. The Environmental Assessment Service is responsible for reviewing environmental assessments of new projects or significant modifications of existing ones, and the decision to grant or reject environmental permits rests with the Environmental Assessment Commission.  On the other hand, the Superintendence for the Environment is responsible for supervising environmental performance during the construction, operation and closure of the projects that have been evaluated for environmental permits, and it is also responsible for enforcing compliance with prevention and atmospheric decontamination plans. The Environmental Law also promotes citizen participation in project evaluation and implementation, providing more opportunities for observations or objections to be made during the environmental evaluation process. Annually, the Superintendence for the Environment audits a sample of approved projects to verify compliance with the environmental permits, and it may pursue fines or sanctions if applicable, which can be challenged in the Environmental Court.

We continuously monitor the impact of our operations on the environment and on the health of our employees and other persons who may be affected by such operations. We have made modifications to our facilities in an effort to eliminate any adverse impacts. Also, over time, new environmental standards and regulations have been enacted, which have required minor adjustments or modifications of our operations. We anticipate that additional laws and regulations will be enacted over time with respect to environmental matters. There can be no assurance that future legislative or regulatory developments will not impose new restrictions on our operations. We are committed to continuously improving our environmental performance through our Environmental Management System (“EMS”). We strive to be leaders in sustainability at a national and international level. In 2020, we began the ISO 14.001 certification process for our operations in the Salar de Atacama and in our Carmen Lithium production facility. This certification is being overseen by TÜV-Rheinland. During 2021 we began the certification process at the Port of Tocopilla, which we successfully concluded at the end of that year. In addition, in 2021 we started this process in Coya Sur.

We participate in voluntary evaluations with companies such as Ecovadis and seek international certifications such as the Responsible Conduct certification from the Chilean Industrial Chemicals Association, which applies to our operations at Nueva Victoria and our port in Tocopilla, and the Protect & Sustain certification from the International Fertilizer Association, which applies to our operations at Coya Sur, the Salar de Atacama, Tocopilla, Antofagasta and Santiago. In 2021, in the Salar de Atacama, we began preparing an external audit with the Initiative for Responsible Mining Assurance (IRMA) for a mining certification process.

We have submitted and will continue to submit environmental impact assessment studies related to our projects to the governmental authorities. We require the authorization of these submissions in order to maintain and to increase our production capacity.

51

International Regulations

We are subject to complex regulatory requirements in the various jurisdictions in which we operate, including the following implemented during 2021:

In 2019, Regulation (EU) 2019/1009 was published, which establishes provisions regarding the market availability of fertilizer products and repeals Regulation (EC) No 2003/2003. During 2021, the annual contaminant evaluation program in fertilizer products was carried out. On the other hand, the updating of the arts of the products marketed in Europe and the evaluation of the raw materials used in this market began.

We continue our active participation as members of the Standing Committee on Precursors of the European Commission, which monitors and assists in the implementation of Regulation (EU) 2019/1148 on the marketing and use of explosive precursors. The invoices of our products covered by this Regulation inform of such a condition so that our users are informed and can take the pertinent measures.

On January 1, 2021, the so-called UK REACH came into force in the United Kingdom. Before October 27, SQM presented the Downstream User Import Notification (DUIN) for its products sold in this market using the figure of the Exclusive Representative.

In June 2021, Chile enacted Law No. 21,349, which establishes regulations on the composition, labeling and marketing of fertilizers and biostimulants. During that year, SQM actively participated through the Chilean Chemical Industry Association in the preparation of the Regulations and Resolutions that implement the Law.

Decree 57 of the Chilean Ministry of Health approving the Regulations for the classification, labeling and notification of hazardous chemicals and mixtures was published in the Official Gazette on February 9, 2021. SQM has actively participated in the public and private implementation committee of this Regulation and through the regulatory affairs committee of the Association of Industrial Chemicals of Chile. During that year, the hazard classification criteria of our products were contrasted so that the safety data sheets reflect the changes established in the regulation.

In 2021, in South Korea, the registration processes of two products under the K-REACH regulation were completed, using the Exclusive Representative model, to facilitate the regulatory compliance of our clients in this market. Additionally, at the SQM commercial office in Seoul, the Korean authority KCMA (Korean Chemical Management Association) was notified of all the products that are going to be imported from the lithium and iodine business lines. In 2021, the process of notifying the safety data sheets of the lithium and iodine business lines marketed in Korea under the K-OSHA regulations to different competent authorities in Korea, including the Ministry of Labor and Employment, also began.

On May 25, 2019, Japan updated its chemical classification and labeling standards (JIS Z 7252: 2019 and 7253: 2019) to align with the sixth version of the UN-GHS. This update has a three-year transition period that ends in May 2022. During 2021, the process of reviewing the Safety Data Sheets and updating the labeling of the products marketed by SQM in Japan was carried out, under the JIS Z 7252 standards: 2019 & 7253: 2019, from the lithium and iodine business lines.

4.D. Property, Plant and Equipment

Mineral Reserves and Resources

Information concerning our mining properties in this Annual Report on Form 20-F has been prepared in accordance with the requirements of subpart 1300 of Regulation S-K, which first became applicable to us for the fiscal year ended December 31, 2021. These requirements differ significantly from the previously applicable disclosure requirements of SEC Industry Guide 7. Among other differences, subpart 1300 of Regulation S-K requires disclosure of mineral resources, in addition to mineral reserves, as of December 31, 2021, both in the aggregate and for each of our individually material mining properties. Our mineral reserves and resources are estimated by individuals deemed Qualified Persons (QP) according to the standards set forth in subpart 1300 of Regulation S-K.

SQM believes it is a production stage company based on the classification of its material properties. SQM reports mineral resource and reserve estimates for development and production stage projects, following the classification done by SQM of its material properties. See the individual property disclosures below for further details regarding the mineral rights, titles, property size, permits and other information for our significant mineral extraction properties.

Mineral resources and reserves are defined in subpart 1300 of Regulation S-K as follows:

· Mineral resource. A concentration or occurrence of 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 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 and justifiable 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.

· Mineral reserve. An estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of a QP, 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.

Under subpart 1300 of Regulation S-K, mineral resources may not be classified as mineral reserves unless the determination has been made by a QP that such mineral resources can be the basis of an economically viable project. The conversion of reported mineral resources to mineral reserves should not be assumed.

Mineral resource classifications are differentiated under subpart 1300 of Regulation S-K, in part, as follows:

· Measured resource. That part of a mineral resource with the highest level of geological confidence; quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a QP to apply modifying factors in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit.

54

· Indicated resource. That part of a mineral resource with a level of geological confidence between that of measured and inferred resources; quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a QP to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.

· Inferred resource. That part of a mineral resource with the lowest level of geological confidence; quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability.

Caliche

Geologists and mining engineers who are QPs prepare our estimates of caliche ore resources and reserves. The resource and reserve figures presented below are estimates and may be subject to modifications due to natural factors that affect the distribution of mineral grades, which would, in turn, modify the recovery of nitrate and iodine. Therefore, no assurance can be given that the indicated levels of recovery of nitrates and iodine will be realized.

We estimate ore resources and reserves based on evaluations, performed by engineers and geologists, of assay values derived from sampling of drillholes and other openings. Drillholes have been made at different space intervals in order to recognize mining resources. Normally, we start with 400x400 meters and then we reduce spacing to 200x200 meters, 100x100 meters and 50x50 meters. The geological occurrence of caliche ore is unique and different from other metallic and non-metallic minerals. Caliche ore is found in large horizontal layers at depths ranging from one to four meters and has an overburden between zero and two meters. This horizontal layering is a natural geological condition and allows us to estimate the continuity of the caliche bed based on surface geological reconnaissance and analysis of samples and trenches.

Salar de Atacama

Hydrogeologists and geologists who are QPs prepare our estimates of the resource and reserve base of potassium, sulfate, lithium and boron dissolved in brines at the Salar de Atacama. We have exploitation concessions through Corfo covering an area of 81,920 hectares, in which we have carried out geological exploitation, brine sampling and geostatistical analysis.

Mt. Holland

Geologists and mining engineers who are QPs

prepared

the mineral resource and reserve estimation for lithium hydroxide contained in pegmatites at Mt. Holland. The mineral reserve has been calculated from the mine plan created from the mineral resource estimation. Wireframes for the geological domains are defined by mineralization style and based on a cut-off grade of 0.5%

lithium oxide.

Mining Rights

The discussion of our mining rights is organized below according to the geographic location of our mining operations. Our caliche ore mining interests are located throughout the valley of the Tarapacá and Antofagasta regions of northern Chile (in a part of the country known as “El Norte Grande”). From caliche ore, we produce products based on nitrates and iodine, and caliche also contains concentrations of potassium. Our mining interests in the brine deposits of the Salar de Atacama are found within the Atacama Desert, in the eastern region of El Norte Grande. From these brines we primarily produce products based on potassium, sulfate, and lithium. Our spodumene mining interests are located in Mt. Holland in Western Australia. From spodumene, we produce lithium hydroxide.

Mining Concessions in Chile

We hold our mining rights in Chile pursuant to mining concessions for exploration and exploitation of mining resources granted pursuant to applicable law in Chile. For a discussion of the mining concessions, see “

Material Individual Properties — El Norte Grande — Mining Concessions for the Exploration and Exploitation of Caliche Ore”

and

“—Salar de Atacama Mining Concessions for Exploitation of Brines.”

As of December 31, 2021, approximately 99% of SQM’s mining interests in Chile were held pursuant to Mining Exploitation Concessions and 1% pursuant to Mining Exploration Concessions. Of the Mining Exploitation Concessions, approximately 97% already have been granted pursuant to applicable Chilean law, and approximately 3% are in the process of being granted. Of the Mining Exploration Concessions, approximately 96% already have been granted pursuant to applicable Chilean law, and approximately 4% are in the process of being granted.

In 2021, we made payments of US$7.6 million to the Chilean government for Mining Exploration and Exploitation Concessions, including the concessions we lease from Corfo. These payments do not include the payments we made directly to Corfo pursuant to the Lease Agreement, according to the percentages of the sales price of products produced using brines from the Salar de Atacama.

The following table shows the Mining Exploitation and Exploration Concessions held by SQM, including the mining properties we lease from Corfo, as of December 31, 2021:

	Exploitation Concessions				Exploration Concessions				Total
Region of Chile	Total Number		Hectares		Total Number		Hectares		Total Number		Hectares
Region I		2,870		539,840		6		1,900		2,876		541,740
Region II		8,938		2,343,701		57		22,500		8,995		2,366,201
Region III and others		469		107,480		2		400		471		107,880
Total		12,277		2,991,021		65		24,800		12,342		3,015,821

The majority of the Mining Exploitation Concessions held by SQM were requested primarily for non-metallic mining purposes. However, a small percentage of our Mining Exploration Concessions were requested for metallic mining purposes. The annual payment to the Chilean government for this group of concessions is higher.

Geological studies over mining properties that were requested primarily for non-metallic mining purposes may show that the concession area is of interest for metallic mining purposes, in which case we must inform the National Geology and Mining Survey (Sernageomin), indicating that the type of substance contained by such Mining Concessions has changed, for purposes of the annual payment for these rights.

Mt. Holland Mining Rights

The Mt. Holland Lithium project development envelope for the Mine and Concentrator is spread across three core mining tenements (M77/1065, M77/1066 & M77/1080), as well as exploration licenses, general purpose licenses and miscellaneous licenses (Project Tenements), covering an approximate area of

4,606

hectares. A summary map showing the main tenements is provided in Figure 2.

Most of the Project Tenements are currently registered under MH Gold, an affiliate of Wesfarmers Limited, and SQM Australia, an affiliate of SQM, in equal interests. Any other tenements are held by MH Gold Pty Ltd or Montague Resources Australia Pty Ltd, both ultimately controlled by Wesfarmers Chemicals, Energy and Fertilizers (WesCEF). The project is

an unincorporated

joint venture

,

in which SQM owns 50% and Wesfarmers Limited owns the remaining 50

% (the “Mt. Holland JV”), and is managed by Covalent Lithium Pty Ltd (“Covalent”), an entity owned 50% by SQM and 50% by Wesfarmers.

Covalent and the joint venturers have entered into an access agreement with Montague and MH Gold that authorizes the Mt. Holland JV to access such tenements as required for the purpose of the Project. Covalent is not the registered holder or applicant of the Project Tenements under the Mining Act of 1978 (WA) (Mining Act).

(1) Comparisons of values may not add due to rounding of numbers and the differences caused by averaging

(2) Salar de Atacama, Chile. The process efficiency is based on the type of extracted brine at each well over the course of the simulation, the average process efficiency over the entire life of mine (LoM) is approximately 51% for lithium and approximately 74% for potassium.

(3) Salar de Atacama, Chile. The average lithium and potassium concentration is weighted by the simulated extraction rates in each well.

(4) Salar de Atacama, Chile. The  mineral resource and reserve estimate considers a 0.05% w/w cut-off grade for lithium based on the cost of generating lithium product, lithium carbonate sales, and the respective cost margin. Based on historical lithium prices from 2010 and the forecast to 2040, a projected lithium carbonate price of US$11,000 per metric ton with the corresponding cost and profit margin is considered with a small increase to accommodate the evaporation area and use of additives. A similar analysis was undertaken for potassium where the cut-off grade of 1% w/w has been set by SQM based on respective costs, sales, and margin.

(5) Salar de Atacama, Chile. This reserve estimate differs from the in-situ base reserve previously reported (SQM, 2020) and considers the modifying factors of converting mineral resources to mineral reserves, including the production wellfield design and efficiency, as well as environmental and process recovery factors. The reserve estimate also considers the expiry of the Lease Agreement in 2030 (end of LoM). The Qualified Persons for the Mineral Reserves are Álvaro Henríquez, Rodrigo Riquelme and Gino Slanzi.

(6) Mt. Holland, Australia . Mineral reserve tonnage and grade have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding. Metallurgical processes are designed for nominal 2Mpta ore feed. Process recovery to concentrate is estimated at 75% for lithium oxide for predominantly Spodumene Mineralization and 0% for other mineralization types. Refinery process recovery is estimated at 85%.  Tantalum recovery is estimated at 0%. A total operating cost of US$4,979 per metric ton for LiOH production was considered in the reserve evaluation. The price, cost, and mass yield parameters, along with the internal constraints of the current operations, result in a mineral reserves cut-off grade of 0.5% Li 2 O based on a selling Lithium Hydroxide price of US$11,000 per ton FOB. The Qualified Person for the Mineral Reserves is David Billington with an effective date: December 15, 2021

(7) El Norte Grande Caliche, Chile.  The cutoff grades of the Proven and Probable Reserves vary according to the required targets at the different mines. The values assigned correspond to the averages of the different sectors. In the case of Pedro de Valdivia, the cut-off grade is for nitrate content, while in all other sites it is only for iodine.

(8) El Norte Grande Caliche, Chile.  The average overall metallurgical recovery of the nitrate and iodine processes contained in the recovered material varies between 50% and 70%.

(9) The mineral resource and reserve estimate considers a cut-off grade of 300ppm for Iodine (I2) based on the production costs of Iodine and derivate products. Based on historical Iodine prices from 2010 and the forecast to 2040, a projected Iodine price of US$35,000 per metric ton is determined, taking in account the corresponding operational, financial and planned investment costs, depreciation, profit margin and taxes. A similar analysis was undertaken for nitrates where the cut-off grade of 5.0% sodium nitrate has been set by SQM based on respective costs for Potassium-Sodium Nitrates (fertilizers) production. A projected price of US$690 per metric ton for sodium-potassium nitrates is considered by SQM in the economic analysis executed from 2010 and the forecast to 2040. In addition, a projected Solar Salts price of US$680 per metric ton has been considered by SQM.  Modifying factors of historical operational use in various of SQM’s mining facilities, are applied to iodine and nitrate grades reported as probable resource estimates. The factors applied to iodine and nitrate grades are 0.9 and 0.85 respectively. Reserve estimates are shown for the area with current environmental permits for mining operations, as well as the surrounding area for which a future environmental permit will be considered. The Qualified Person for the Nueva Victoria and Pampa Orcoma Mineral Reserves is Donald Hulse, while the Qualified Persons for the Pedro de Valdivia and Pampa Blanca Mineral Reserves are Marco Lema and Marta Aguilera.

(1) Comparison of values may not add due to the rounding of numbers and differences caused by averaging.

(2) Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves upon the application of modifying factors.

(3) Salar de Atacama, Chile. Mineral resources are reported as in-situ and exclusive of Mineral Reserves, where the estimated Mineral Reserve without processing losses during the reported LOM and real declared extraction from 2021 were subtracted from the Mineral Resource inclusive of Mineral Reserves. A direct correlation between Proven Reserves and Measured Resources, as well as Probable Reserves and Indicated Resources was assumed.The Qualified Persons for the Mineral Resources are Álvaro Henríquez, Rodrigo Riquelme and Gino Slanzi.

(4) Salar de Atacama, Chile. The mineral resource and reserve estimate consider a 0.05% w/w cut-off grade for lithium based on the cost of generating lithium product, lithium carbonate sales, and the respective cost margin. Based on historical lithium prices from 2010 and the forecast to 2040, a projected lithium carbonate price of US$11,000 per/ metric ton with the corresponding cost and profit margin is considered with a small increase to accommodate the evaporation area and use of additives. A similar analysis was undertaken for potassium where the cut-off grade of 1% w/w has been set by SQM based on respective costs, sales, and margin.

(5) Mt. Holland, Australia. Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding. Mineral resources are reported as exclusive of mineral reserves. Resource disclosed corresponds to the resources attributable to SQM. Mineral resources are not mineral reserves and do not have demonstrated economic viability. Resources have been reported as in situ (hard rock within optimized pit shell). Pit optimization and economics for derivation of cut off grade include mine gate pricing of US$800 FOB per ton of 6% Li2O concentrate., AUS$19 per bcm mining cost (LoM average cost-variable by depth), AU$65 processing cost per ton. Mining dilution set at 5% and recovery at 95%. Royalty fees 5%. The optimization considered for the concentrator is 75%. Costs estimated in Australian Dollars were converted to US Dollars based on an exchange rate of AU$0.75:US$1.00. These economics define a cut-off grade of 0.50% Li 2 O. Kerry Griffin is the 65 QP responsible for the mineral resource estimate with an effective date: October 6, 2021. No material changes since the last update.

(6) El Norte Grande, Caliche, Chile. To calculate Measured Resources, SQM uses the RGM100T and RGM50 data results combined in a 3D block model built using krikeage and applying some criteria: caliche thickness ≥ 2.0 m; overload thickness ≤3.0 m; waste / Mineral Ratio ≤ 1.5; and cut-off grades of NaNO3 (5%) and Iodine (300 ppm). To calculate Indicated Resources, SQM uses the RGM100 and RGM200 data results combined using a geometric model. To evaluate Probable Reserves a reduction on grades mut be consider as consequence of the deposit geological variability which determines a contrasting decrease in grades by going from 200x200m research grids to lower 100T (~70x70m) or 50x50m grids. The Mineral Resource estimates were prepared by Donald Hulse (who is the independent Qualified Person for these Mineral Resource estimates), reported using the S-K 1300 Definition Standards adopted December 2018.. The Qualified Persons for the Pedro de Valdivia, María Elena and Pampa Blanca Mineral Resources are Marco Lema and Marta Aguilera.

(7) El Norte Grande, Caliche, Chile. The estimate was completed using a SG of 2.1 ton/m³. Cut-off grade for Iodine is 300 ppm. The cutoff grades of the mineral resources vary according to the required targets at the different mines. The values assigned correspond to the averages of the different sectors. In the case of Pedro de Valdivia, the cut-off grade is for nitrate content, while in all other sites it is only for iodine. The mineral reserve estimate considers a cut-off grade of 300ppm for Iodine (I2) based on the production costs of Iodine and derivate products. Based on historical Iodine prices from 2010 and the forecast to 2040, a projected Iodine price of 35,000 USD/t is determined, taking in account the corresponding operational, financial and planned investment costs, depreciation, profit margin and taxes. A similar analysis was undertaken for nitrates where the cut-off grade of 5.0% NaNO3 has been set by SQM based on respective costs for Potassium-Sodium Nitrates (fertilizers) production. A projected price of 690 USD/t for sodium-potassium nitrates is considered by SQM in the economic analysis executed from 2010 and the forecast to 2040. In addition, a projected Solar Salts price of 680 USD/t has been considered by SQM.

Material Individual Properties

To determine our individually material mining operations in accordance with subpart 1300 of Regulation S-K, management considered both quantitative and qualitative factors, assessed in the context of our overall business and financial condition. Such assessment included our aggregate mining operations on all of our mining properties, regardless of the stage of production or the type of mineral produced. Quantitative factors included, among others, mining operations’ relative contributions to our aggregate historical and estimated revenues, cash flows, and EBITDA. Qualitative factors may include, as applicable, capital expansion plans, long-term pricing outlook, the regulatory environment and various strategic priorities. We concluded that, as of December 31, 2021, our individually material mines are the caliche ore mines

at Nueva Victoria and Pampa Orcoma

in El Norte Grande region of Chile, the brines in the Salar de Atacama in Chile and the Mt. Holland lithium project in Western Australia. We will update our assessment of individually material mines on an annual basis. The reserve and resource tables that follow do not include comparative information as of December 31, 2020 as we did not present such data previously under the SEC Industry Guide 7 requirements and such data is not required to be presented in connection with the adoption of the disclosure requirements of subpart 1300 of Regulation S-K.

62

The information that follows relating to such individually material properties is derived, for the most part, from, and in some instances is an extract from, from the TRS relating to such properties prepared in compliance with Item 601(b)(96) and subpart 1300 of Regulation S-K. 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 TRS, incorporated herein by reference and made a part of this Annual Report on Form 20-F. The relevant TRS for the

Nueva Victoria property, the

Salar de Atacama property, the Mt. Holland lithium project

and

the Pampa Orcoma property are included as Exhibits 96.1, 96.2, 96.3 and 96.4, respectively, to this Annual Report on Form 20-F.

El Norte Grande Caliche, Chile

Our mining operations are concentrated in the First Region of Chile, where we mainly work in the mining areas of Tente en el Aire,Nueva Victoria Norte/West and Torcaza.

The El Norte Grande Caliche, found in Regions I and II of northern Chile, corresponds to flat areas or “pampas”, that have been thoroughly explored. Results indicate that these prospects hold mineralization of nitrate and iodine. The area is accessible from Santiago through Route 5. The mineralization is stratiform in style, with a wide areal distribution, forming "spots" of several kilometers in extension, where mineralization thicknesses are variable. As a result of geological activity over time (volcanism, weathering, faulting) the deposits can be found as continuous mantles. Environmental permits for mining operations, and the corresponding Environmental Qualification Resolution, grant access to the required water and electricity supply, as well as the infrastructure required for the mining operation.

Facilities

Nueva Victoria

The Nueva Victoria mine and facilities are located 140 kilometers southeast of Iquique and are accessible by highway. Since 2007, the Nueva Victoria mine includes the mining properties Soronal, Mapocho and Iris. At this site, we use caliche ore to produce salts rich in nitrates and iodine, through heap leaching and the use of solar evaporation ponds. The main production facilities at this site include the operation centers for the heap leaching process, the iodide and iodine plants at Nueva Victoria and Iris and the evaporation ponds at the Sur Viejo sector of the site. The areas currently being mined are located approximately 25 kilometers northeast of Nueva Victoria. Solar energy and electricity are the primary sources of power for this operation. The nitrate-rich salts are sent to Coya Sur, which is a process plant located approximately 15 kilometers south of María Elena, and production activities undertaken there are associated with the production of potassium nitrate and finished products. The main production plants at this site include four potassium nitrate plants with a total capacity of 1,300,000 metric tons per year. There are also four production lines for crystallized nitrates, with a total capacity of 1,200,000 metric tons per year, and a prilling plant with a capacity of 360,000 metric tons per year. The potassium nitrate produced at Coya Sur is an intermediate product that is used as a raw material for the production of finished products (crystallized nitrates and prilled nitrates). Therefore, the production capacities listed above are not independent of one another and cannot be added together to obtain an overall total capacity. Natural gas is the main source of energy for our Coya Sur operation.

Pampa Orcoma

The Pampa Orcoma Project is located in the Tarapacá Region of northern Chile. It is situated 99 kilometers to the northeast of the city of Iquique, in the community of Huara. The property covers an area of 10,296 hectares and is composed of 45 mining concessions. The Pampa Orcoma Project aims to produce iodide, iodine and nitrate-rich salts from the processing of caliche that will be extracted from deposits rich in this mineral. The Pampa Orcoma Mining Plan considers an initial extraction of caliche at a rate of 11 Mt/year between 2024-2026, followed by an extraction rate of 20 Mt/year from 2027 onwards. For the period 2024-2040 a total extraction of 340 Mt of caliche is projected with an average grade of 413 ppm iodine and 6.9% nitrates. The production process to obtain iodine as the main product, along with salts rich in sodium nitrate and potassium nitrate as by-products, involves leaching with seawater or with recirculated solutions to obtain a solution rich in iodate, which will then be treated in chemical plants to transform it into elemental iodine in prill format. The Pampa Orcoma Project contemplates the construction of the following facilities: iodide and iodine production plants, with a capacity of 2,500 t/year (of equivalent iodine), evaporation ponds to produce salts rich in nitrate at a rate of 320,325 t/year and a seawater adduction pipe to meet the water needs.  Solar energy and electricity are the primary sources of power for this future operation.

Reserves and Resources

According to our experience in caliche ore, the grid pattern drillholes with spacings between 50 and100 meters produce data on the caliche resources that is sufficiently defined to consider them measured resources and then, adjusting for technical, economic and legal aspects, as proven reserves. These reserves are obtained using the Kriging Method and the application of operating parameters to obtain economically profitable reserves.

Similarly, the information obtained from detailed geologic work and samples taken from grid pattern drillholes with spacings between 100 and 200 meters can be used to determine indicated resources. By adjusting such indicated resources to account for technical, economic and legal factors, it is possible to calculate probable reserves. Probable reserves are calculated by using a polygon-based methodology and have an uncertainty or margin of error greater than that of proven reserves. However, the degree of certainty of probable reserves is high enough to assume continuity between points of observation.

The conversion of resources into reserves requires consideration of modifying factors, the most relevant of which is the existence of a valid environmental license (RCA or Sectorial Authorization). The criteria for converting resources into reserves, based on the environmental license modifying factor criterion, adopted for caliche mines are as follows:

66

1. Unit tonnage conversion criteria in both measured resources and indicated resources.

2. Grade conversion criteria: unit factor in measured resources and lower than unit and variable according to the mine, in the Iodine and Nitrate grades, for the indicated resources, due to the variability of the deposit.

3. Application of the factor associated with related environmental permit, not qualifying as reserves the resources defined in sectors without an environmental permit and qualifying as proven/probable reserves the measured/indicated resources associated with sectors with an effective environmental permit or Sectorial Authorization in force.

The proven and probable reserves shown above are the result of the evaluation of approximately 18.5% of the total caliche-related mining property of our Company. However, we have explored more intensely the areas in which we believe there is a higher potential of finding high-grade caliche ore minerals. The remaining 81.4% of this area has not been explored or has had limited reconnaissance, which is not sufficient to determine the potential and hypothetical resources. In 2020, we did not carry out basic reconnaissance of new mining properties. With respect to detailed explorations, in 2020, we did not carry out recategorizations of indicated resources. We did not carry out basic exploration on new properties in 2021. An advanced exploration program is already designed for 2022, aimed at covering an area of 12,475 hectares in Tente en el Aire, Pampa Orcoma, Franja Oeste and Sector V of Pampa Blanca. The reserves shown in these tables are calculated based on properties that are not involved in any legal disputes between SQM and other parties.

We maintain an ongoing program of exploration and resource evaluation on the land surrounding our production mines, and other sites for which we have the appropriate concessions.

Transportation and Storage

The nitrate finished products are produced at our Coya Sur facilities and then transported via trucks to the Port of Tocopilla terminal where they are stored and shipped in bulk or packaged in polypropylene bags, polyethylene or polypropylene bags. The latter can also be transported and stored in an alternative port (Mejillones) for later shipment.

The potassium chloride is produced at our Salar de Atacama facilities and we transport it by truck, either to the Port of Tocopilla terminal, the Coya Sur facility or the alternative Port of Mejillones for its shipment. The product transported to Coya Sur is an intermediate product that is used as a raw material for the production of potassium nitrate. The product transported to the Port of Tocopilla or Mejillones is a final product that will be shipped or transported to the client or affiliate. The nitrate raw material for the production of potassium nitrate in Coya Sur is currently produced at Nueva Victoria.

The lithium chloride solution, which contains a high concentration of boron, produced at our Salar de Atacama facilities, is transported to the lithium carbonate plant at the Carmen Lithium facility area where the finished lithium carbonate is produced. Part of the lithium carbonate is provided to the adjacent lithium hydroxide plant where the finished lithium hydroxide is produced. These two products are packed in packagings of distinct characteristics such as polyethylene bags, multi-layer or polypropylene FIBC big bags, stored within the same facilities and secured in storerooms. Thereafter, they are consolidated into containers that are transported by trucks to a transit warehouse or directly to port terminals for their subsequent shipment. The port terminals used are currently suited to receive container ships and are situated in Antofagasta, Mejillones and Iquique. Lithium carbonate can also be transported in packaged format both to Tocopilla and to an alternative port (Mejillones) to be shipped in break bulk format.

69

Iodine obtained from the same caliche used for the production of nitrates, is processed, packaged and stored exclusively in the Pedro de Valdivia and Nueva Victoria facilities. The packaging used for iodine are drums and polypropylene FIBC big bags with an internal polyethylene bag and oxygen barrier, which are consolidated into containers and sent by truck to port terminals suited for their management, principally located in Antofagasta, Mejillones and Iquique. Thereafter, they are sent to distinct markets by container ship or by truck to Santiago where iodine derivatives are produced in the Ajay-SQM Chile plants. Drums and maxibags can also be transported on flat ramps to an alternative port (Mejillones) to be shipped in break bulk format.

We own and operate the port and storage facilities at the Port of Tocopilla terminal for the transportation and management of finished products and consumable materials. See

“Transportation and Storage Facilities in Chile.”

Mining Concessions for the Exploration and Exploitation of Caliche Ore

We hold our mining rights for caliche ore pursuant to mining concessions for exploration and exploitation of mining resources that have been granted pursuant to applicable law in Chile:

(1) “Mining Exploitation Concessions”: entitle us to use the land in order to exploit the mineral resources contained therein on a perpetual basis, subject to annual payments to the Chilean government; and

(2) “Mining Exploration Concessions”: entitle us to use the land in order to explore for and verify the existence of mineral resources for a period of two years, at the expiration of which the concession may be extended one time only for two additional years, if the area covered by the concession is reduced by half. We may alternatively request an exploitation concession in respect of the area covered by the original exploration concession, which must be made within the timeframe established by the original exploration concession.

A Mining Exploration Concession is generally obtained for purposes of evaluating the mineral resources in a defined area. If the holder of the Mining Exploration Concession determines that the area does not contain commercially exploitable mineral resources, the Mining Exploration Concession is usually allowed to lapse. An application also can be made for a Mining Exploitation Concession without first having obtained a Mining Exploration Concession for the area involved.

As of December 31, 2021, the surface area covered by Mining Exploitation Concessions that have been granted in relation to the caliche resources of our mining sites is approximately 558,500 hectares. In addition, as of December 31, 2021, the surface area covered by Mining Exploration Concessions in relation to the caliche resources of our mining sites is approximately 700 hectares. We have not requested additional mining rights.

Salar de Atacama, Chile

The operations of SQM in the Salar de Atacama are located in the Antofagasta Region of Chile, which covers the El Loa Province and the San Pedro de Atacama commune. The Salar de Atacama Project is currently in operation for the treatment of brines to obtain lithium and potassium salts, and as such it is in a production stage. The Salar de Atacama nucleus is owned by the Corporación de Fomento de la Producción (CORFO) of Chile, which grants special operating contracts or administrative leases to private companies for the extraction of brine. SQM and Albemarle have a lease agreement with Corfo to extract and produce lithium from brines stored in the Salar de Atacama deposit. Consequently, SQM must follow the terms of the agreement and also the conditions established in numerous RCA’s in order to retain operations in the Salar de Atacama. Exploration is routinely carried out within the established areas.

SQM leases an area of about 1,400 square kilometers with permission to extract brines from an area of 820 square km with two core operations. It currently produces lithium at its southwest operation. The lease was signed in 1993 and expires on December 31, 2030.

70

The closest cities are Calama and Antofagasta, located 160 and 230 kilometers west of the site, respectively. From Calama, the road to the site is through Route R-23, and from Antofagasta, it is via Route B-385.

SQM’s mineral resource in the Salar de Atacama is constituted by in-situ brine within a porous media, and the resource estimate depends on the brine concentration, aquifer geometry, and drainable interconnected pore volume. Within SQM’s concessions, the lithium and potassium resources were estimated based on extensive exploration and many depth-specific samples from each unit.

The geology in the Salar de Atacama is characterized by Paleozoic to Holocene igneous and sedimentary rocks, as well as recent unconsolidated clastic deposits and evaporitic sequences. The salt flat itself resides in a tectonic basin of recent compressive-transpressive behavior and is bounded by high angle reverse and strike-slip faults. The Salar de Atacama surface is constituted by recent evaporitic deposits, where over time the process of evaporation has precipitated salts, and surficial clastic sediments are found mainly along the salt flat margins. The salt crust is mainly composed of halite, sulfates, and occasional organic matter, with alluvial facies in the peripheral zones. Evaporitic and clastic deposits within the salt flat host brine with depth and are delimitated and cut by local fault systems; several structural blocks have been identified due to recent fault displacement.

The salar system of the Salar de Atacama basin is typical of a mature salar, with a nucleus constituted by a thick section of halite (>90%) with sulfate and a minor percentage of clastic sediments, as well as some interbedded clay sediments and sulfates over a surface area of 1,100 square kilometers and down to a depth of 900 meters. Within SQM’s concessions, mineralization includes lithium and potassium-rich brine in porous media of distinct zones and depths of the Salar de Atacama nucleus.

Facilities

Our facilities at the Salar de Atacama are located 210 kilometers to the east of the city of Antofagasta and 190 kilometers to the southeast of the city of María Elena. At this site we use brines extracted from the salar to produce potassium chloride, potassium sulfate, and lithium chloride solutions, which are subsequently sent to our lithium carbonate plant at the Carmen Lithium facility for processing. The main production plants at this site include the solar evaporations ponds systems, the potassium chloride flotation plants (MOP-H I and II), the potassium carnallite plants (PC I and PC I extension), the potassium sulfate flotation plant (SOP-H), the potassium chloride drying plant (Dual Plant or MOP-S), the potassium chloride compacting plant (MOP-G3), the potassium sulfate drying plant (SOP-S) and the potassium sulfate compacting plant (SOP-G). The energy used consists primarily of solar energy, as well as electricity, fuel and gas sources.

The Carmen Lithium facility site is located approximately 20 kilometers east of Antofagasta. The production plants at this facility include the lithium carbonate plant, with a production capacity of 120,000 tons per year, and the lithium hydroxide plant, with a production capacity of 21,500 tons per year. During 2022, we expect to expand the production capacity to produce 180,000 tons and 30,000 tons of lithium carbonate and lithium hydroxide per year, respectively. Lithium chloride (LiCl) solution is concentrated and purified in the lithium chemical plants through stages of contaminant removal (specifically boron, magnesium and calcium content) and conversion reaction to produce: technical grade lithium carbonate; battery grade lithium carbonate; technical grade lithium hydroxide; and battery grade lithium hydroxide. Electricity and natural gas are the main sources of energy for the operations of our Carmen Lithium facility.

71

The following table provides a summary of our Salar de Atacama production facilities as of December 31, 2021:

Facility	Type of Facility	Approximate Size (hectares) (1)		Nominal Production Capacity (thousands of metric tons/year)	Weighted Average Age (years) (2)		Gross Book Value (millions of US$) (2)
Salar de Atacama (3)	Potassium chloride, potassium sulfate, lithium chloride, and boric acid production		35,911	Potassium chloride: 2,680 Potassium sulfate: 245 Boric acid: 15		13.2		1,592.9
Carmen Lithium facility, Antofagasta (3)	Lithium carbonate and lithium hydroxide production		126	Lithium carbonate: 120 Lithium hydroxide: 21.5		7.3		504.9

(1) Approximate size considers both the production facilities and the mine for the Salar de Atacama. Mining areas are those authorized for exploitation by the environmental authority and/or Sernageomin.

(2) Weighted average age and gross book value correspond to production facilities, excluding the mine, for the Salar de Atacama.

(3) Includes production facilities and solar evaporation ponds. During 2019, we began to work on the expansion of discard deposit area of the new lithium hydroxide plant and accumulation ponds.

We directly or indirectly through subsidiaries own, lease or hold concessions over the facilities at which we carry out our operations. Such facilities are free of any material liens, pledges or encumbrances, and we believe they are suitable and adequate for the business we conduct in them.

Extraction Yields

The following table shows certain operating data relating to each of our Salar de Atacama operations for 2021, 2020 and 2019:

(in thousands, unless otherwise stated)	2021		2020		2019
Salar de Atacama (1)
Metric tons of lithium carbonate produced		108.4		72.2		62.3
Metric tons of potassium chloride and potassium sulfate and potassium salts produced		1,407		1,476		1,049

(1) Lithium carbonate is extracted at the Salar de Atacama and processed at our facilities at the Carmen Lithium facility near Antofagasta. Potassium salts include synthetic sylvinite produced in the plant and other harvested potassium salts (natural sylvinite, carnallites and harvests from plant ponds) that are sent to Coya Sur for the production of crystallized nitrates.

Reserves and Resources

The mineral reserve was estimated for potassium and lithium dissolved in brines of the Salar de Atacama considering modifying factors for converting mineral resources to mineral reserves, including the production wellfield design and efficiency, pumping scheme, and recovery factors for lithium and potassium. The projected future brine extraction was simulated using a groundwater flow and solute transport model. Numerical modeling was supported by a detailed calibration process and hydrogeological, geological, and hydrochemical data within the exploitation concessions. Based on the current SQM production wellfield, as of December 31, 2021, which corresponds to the effective date of mineral resource and reserve declaration that is most representative of 2021, we estimate that our proven and probable reserves of lithium and potassium are as follows:

(1),(2),(3),(4),(5),(6)

	Brine Volume (Million cubic meters)		Amount (Million metric tons)		Grades/Qualities (wt.%)		Cut-off grades (wt.%)		Metallurgical recovery (%)

Total mineral reserves		290		6.03		2.22		1.0		74

(1) The process efficiency is based on the type of extracted brine at each well over the course of the simulation, the average process efficiency over the entire LoM is approximately 51% for lithium and approximately 74% for potassium.

(2) The values in the “Amount” column correspond to contained metallic lithium (LME) and potassium.

(3) The average lithium and potassium concentration is weighted by the simulated extraction rates in each well

(4) Comparisons of values may not add due to rounding of numbers and the differences caused by averaging

(5) The mineral resource and reserve estim ate considers a 0.05% w/w cut-off grade for lithium based on the cost of generating lithium product, lithium carbonate sales, and the respective cost margin. Based on historical lithium prices from 2010 and the forecast to 2040, a projected lithium carbona te price of US $1 1 ,000 per metric ton with the corresponding cost and profit margin is considered with a small increase to accommodate the evaporation area and use of additives. A similar analysis was undertaken for K where the cut-off grade of 1% w /w has been set by SQM based on respective costs, sales, and margin.

(6) This reserve estimate differs from the in-situ base reserve previously reported by SQM in 2020 (SQM, 2020) and considers the modifying factors of convert ing mineral resources to mineral reserves, including the production wellfield design and efficiency, as well as environmental and process recovery factors. The reserve estimate also considers the expiry of the Lease Agreement in 2030 (end of LoM). The Qual ified Persons for the Mineral Reserves are Álvaro Henríquez, Rodrigo Riquelme and Gino Slanzi.

Production well locations are based on the Measured and Indicated Resource zones. Due to the mixing of brines over time, hydrogeological processes, and pumping effects, the mineral reserve was classified based on time:

73

· Proven Reserves were specified for the first 5 years of the simulation given that the model is adequately calibrated to the 2015-2020 period, and the initial portion of the projected simulation has higher confidence due to less expected short-term changes in pumping, conceptual hydraulic parameters, and the water balance, among other factors.

· Probable Reserves were conservatively assigned for the last 5 years of the simulation considering that the numerical model will be continually improved and recalibrated in the future due to potential medium to long term changes in neighboring pumping, conceptual hydraulic parameters, and the water balance, among other factors.

Probable reserves and inferred resources are being continually explored in order to be able to reclassify them as proven reserves and indicated or measured resources, respectively. This exploration includes systematic packer testing, chemical brine sampling, and long-term pilot production pumping tests.

Complementing the reserve information, SQM has an environmental impact assessment (RCA 226/06) which defines a maximum brine extraction until the end of the Lease Agreement (December 31, 2030).

Considering the authorized maximum net brine production rates under (RCA 226/06) and voluntary reduction plan announced by SQM, which is characterized by a reduction in future pumping from 1,280 L/s to 822 L/s during the 10-year LoM, a total of approximately 330 million cubic meters of brine will be extracted from the producing wells, corresponding to 0.81 million metric tons of lithium (without considering processing losses).

The lithium and potassium resource were classified into 3 categories (Measured, Indicated, Inferred) according to the amount of information from the hydrogeological units, as well as geostatistical criteria. Hydrogeological knowledge was prioritized as the first classification criterion based on exploration, monitoring, and historical production data, while geostatistical variables were used as a secondary criterion. We estimate that our lithium and potassium resources as of December 31, 2020, which we also consider as an adequate representation of December 31, 2021, are as follows:

(1) Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves upon the application of modifying factors.

(2) . Mineral Resources are reported as in-situ and exclusive of Mineral Reserves , where the estimated Mineral Reserve without processing losses during the reported LoM (Chapter 12) and real declared extraction from 2021 were subtracted from the Mineral Resource inclusive of Mineral Reserves. A direct correlation between Proven Reserves and Measured Resources, as well as Probable Reserves and Indicated Resources was assumed .

(3) Effective porosity was utilized to estimate the drainable brine volume based on the measurement techniques of the SQM porosity laboratory (Gas Displacement Pycnometer). The QP considers that the high frequency sampling of effective porosity, its large dataset, and general lack of material where specific retention can be dominant permits effective porosity to be a reasonable parameter for the resource estimate.

(4) The values in the “Amount” column correspond to contained metallic lithium (LME) and potassium.

(5) Comparison of values may not add due to the rounding of numbers and differences caused by averaging.

(6) The mineral resource and reserve estimate considers a 0.05% w/w cut-off grade for lithium based on the cost of generating lithium product, lithium carbonate sales, and the respective cost margin. Based on historical lithium prices from 2010 and the forecast to 2040, a projected lithium carbonate price of US$11 ,000 per metric ton with the corresponding cost and profit margin is considered with a small increase to accommodate the evaporation area and use of additives. A similar analysis was undertaken for potassium where the cut-off grade of 1% w/w has been set by SQM based on respective costs, sales, and margin. 

(7) Álvaro Henriquez is the QP responsible for the Mineral Resources.

In regard to the amount of Measured and Indicated resources extracted during the 10-year

LoM

, the total extracted reserve without processing losses represents only 8.9% of the total Measured + Indicated Resource, and for potassium, the total extracted reserve without processing losses represents only 10.5% of the total Measured + Indicated Resource; this is more than sufficient to satisfy the requirements of RCA 226/06 and the Voluntary Extraction Reduction Plan for the project until the end of the current

LoM

.

Mining Concessions for the Exploitation of Brines at the Salar de Atacama

As of December 31, 2021, our subsidiary SQM Salar held exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement provides for SQM Salar to (i) make quarterly lease payments to Corfo based on product sales from leased mining properties and annual contributions to research and development, to local communities, to the Antofagasta Regional Government and to the municipalities of San Pedro de Atacama, María Elena and Antofagasta, (ii) maintain Corfo’s rights over the Mining Exploitation Concessions and (iii) make annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030.

Under the terms of the Project Agreement, Corfo has agreed that it will not permit any other person to explore, exploit or mine any mineral resources in the approximately 140,000 hectares area of the Salar de Atacama mentioned above. The Project Agreement expires on December 31, 2030.

SQM Salar holds an additional 240,052 hectares of constituted Mining Exploitation Concessions in areas near the Salar de Atacama, which correspond to mining reserves that have not been exploited. SQM Salar also holds Mining Exploitation Concessions that are in the process of being granted covering 6,536 hectares in areas near the Salar de Atacama.

In addition, as of December 31, 2021, SQM Salar held Mining Exploration Concessions covering approximately 9,100 hectares and has not applied for additional Mining Exploration Concessions. Exploration rights are valid for a period of two years, after which we can (i) request a Mining Exploitation Concession for the land, (ii) request an extension of the Mining Exploration Concession for an additional two years (the extension only applies to a reduced surface area equal to 50% of the initial area) or (iii) allow the concession to expire.

According to the terms of the Lease Agreement, with respect to lithium production, the Chilean Comission on Nuclear Energy (CCHEN) established a total accumulated extraction limit set as amended by the Corfo Arbitration Agreement in January 2018, up to 349,553 metric tons of lithium metallic equivalent (1,860,670 tons of lithium carbonate equivalent), which is in addition to the approximately 64,816 metric tons of lithium metallic equivalent (345,015 tons of lithium carbonate equivalent) remaining from the originally authorized amount in the aggregate for all periods while the Lease Agreement is in force. As of December 31, 2021, only 9 years remain on the term of the Lease Agreement. See “Item 3.D. Risk Factors” and “Item 8.A.7 Legal Proceedings.”

The environmental permit Resolución de Calificación Ambiental, RCA N° 226/2006, issued on October 19th, 2006, by COREMA (Comisión Regional del Medio Ambiente or Regional Environmental Commission) authorizes SQM to extract brines via pumping wells from two areas in the western and southwestern portions of the areas defined in the Lease Agreement. SQM refers to these brine extraction areas as AAE zones (Áreas Autorizadas para la Extracción or Authorized Areas of Extraction), and they are further divided based on the products historically generated in each sector: (i) The northern portion is denominated the AAE-SOP, where “SOP” signifies sulfato de potasio (potassium sulfate product), and it covers a surface area of 10,512 ha which is equivalent to 29.27% of the total AAE area; (ii) the southern portion is referred to as AAE-MOP, where “MOP” indicates muriato de potasio (potassium chloride product), covering a surface area of 25,399 ha that is equivalent to 70.73% of the total AAE area.

SQM routinely carries out exploration activities within the areas involved in the Lease Agreement and authorized by the Environmental Permits. These are aimed at maintaining the amount of wells needed for production.

76

The water that SQM uses for its mineral production in the Salar de Atacama is obtained from wells located in the alluvial aquifer on the eastern edge of the Salar, for which the company has rights to use groundwater as well as the corresponding environmental authorization (RCA 226/2006). As part of the voluntary sustainability commitment assumed by SQM in 2020, the company will reduce its water consumption by up to 50% in 2030.

SQM’s operations are subject to certain risk factors that may affect the business, financial conditions, cash flow, or SQM’s operational results, such as: the potential inability to extend or renew mineral exploitation rights in the Salar de Atacama beyond the defined expiration date (December 31st, 2030) in the CORFO-SQM lease agreement; risks related to being a company based in Chile; potential political risks as well as changes to the Chilean Constitution and legislation may affect development plans, production levels, and costs; and risks related to financial markets.

Mt. Holland Lithium Project, Australia

Facilities

The Mount Holland project is an integrated lithium project in Western Australia consisting of (i) an open pit mine and lithium concentrator operation, at Mount Holland, 120 km southeast of Southern Cross, and (ii) a lithium hydroxide (LiOH) refinery located in the Town of Kwinana, 26.5 km from the port of Fremantle, from where the LiOH will be shipped.

The project is an unincorporated joint venture in which SQM owns 50% and Wesfarmers Limited, through a wholly owned subsidiary, owns the remaining 50% and is managed by Covalent Lithium Pty Ltd, an entity owned 50% by SQM and 50% by Wesfarmers.

The project is accessed by land using the Parker Range Road and Marvel Loch-Forrestania road, which are an all-season gravel road. The Parker Range road is connected to the Great Eastern Highway which is a paved road with connectivity to Southern Cross, Kalgoorlie and Perth. Also, the project has access by air using an airstrip and associated infrastructure in the southern part of the mine.

On September 11, 2017, Kidman Resources Limited (Kidman) and SQM entered into an asset sale agreement

, pursuant to which

SQM acquired its interest in the tenements for a total investment of SQM of US$110 million, consisting of an initial payment of US$25 million and a deferred payment of US$85 million, both payments subject to certain preceding conditions.

All payments

were completed by December 2018. In the asset sale agreement, the parties also agreed to form an unincorporated joint venture to mine and process spodumene ore into spodumene concentrate or lithium hydroxide. The

Mt. Holland JV

was established by the unincorporated joint venture agreement dated December 21, 2017, between SQM Australia and MH Gold, a then wholly owned subsidiary of Kidman Resources Limited (Kidman). Wesfarmers acquired Kidman Resources Limited in 2019, which resulted in Wesfarmers taking over Kidman Resources’ interest in the Mt Holland JV on September 23, 2019.

SQM and Wesfarmers announced a positive investment decision in February 2021 following the completion of a feasibility study by Covalent. The Mt. Holland project is currently in development stage. Most construction contracts have been awarded and are underway, including the mining contract, the concentrator plant engineering, procurement and construction contract and the refinery construction contracts.

The Mt. Holland project is focused on the exploitation of the resource in the Earl Grey pegmatite group. The Earl Grey pegmatite group consists of a main tabular pegmatite body flanked by numerous narrower hanging wall and footwall apophyses. The pegmatite has a strike length of at least 1 km, and a dip extent of over 2 kilometers and a thickness of up to 100 meters. The pegmatites become progressively narrower and more branched to the south and the east of the main pegmatite until even the main body divides into several narrower dikes. Narrow blocks of enclosed wall rock rafts are present within some areas of the pegmatites.

The pegmatites intrude with an approximate strike of 210° to 220° and dip of 5° to 15° to the northwest. At their western margin, the pegmatites appear to be affected by gentle folding. The dip of the pegmatites is variable, with the pegmatite steepening from sub-horizontal in the south to 10° to 15° to the northwest north of the Earl Grey gold pit.

77

Extensive exploration supports the characterization of the Earl Grey Pegmatite, as the resource and reserve estimation, and it is comprised of surface mapping and extensive subsurface drilling carried out on the property in consideration that the pegmatite is not outcropping in the area. Exploration has predominantly been carried out by Kidman Resources since 2016, for the discovery and resource definition. Since 2020, Covalent has conducted additional diamond drilling for metallurgical sampling, grade control drilling campaigns and improvement definition of the Orebody geometry in the proposed starter pit area.

The majority of drillholes present at Earl Grey have been drilled using reverse circulation (RC) standard drilling techniques. Diamond drilling comprises drillholes with core diameters of 47.6mm, 50.5mm, 63.5mm and 85mm, which are drilled for geological, metallurgical, and geotechnical purposes. Recoveries for Reverse Circulation Drilling. pre-collar and Reverse Circulation drill holes range between 70-90% in this geological/geomorphological setting. Recoveries for the diamond drilling drill core are in the order of 95-100%. Recoveries decrease where shear zones or other structural disruptions have been intersected. The orientation of the drillholes is at relatively acute angles (less than 90º), and therefore the intersected length is not considered as a representation of the pegmatite true thickness; its real thickness is determined through geologic modelling.

Resource drilling was initially carried out on wide spacing to determine the extent of the mineralization. This was followed up by a drilling program on a 50 by 50 meter grid to support the resource estimate. Through the Project development in 2020, the proposed starter pit location was identified and the 2020 grade control drilling program was designed to provide in-fill drilling in this area at a higher density. This information will inform mine design during the initial start-up years and supports the current resource and reserve definition.

Transportation and Storage Facilities in Chile

The transportation of our products is carried out by trucks that are operated by dedicated third parties through long-term contracts. Furthermore, we own port and storage facilities for the transportation and management of finished products and consumable materials.

Our main centers for the production and storage of raw materials are the Nueva Victoria, Coya Sur and Salar de Atacama facilities. Other facilities include chemical plants for the finished products of lithium carbonate and lithium hydroxide at the Carmen Lithium facility. The Port of Tocopilla terminal, which we own, has a surface area of approximately 22 hectares and is the principal facility for the storage and shipment of our bulk products and packaged potassium chloride (MOP), nitrates and lithium carbonate.

The Port of Tocopilla terminal facilities cover approximately 22 hectares and are located approximately 186 kilometers north of Antofagasta, approximately 124 kilometers west of María Elena and Coya Sur and 372 kilometers to the west of Salar de Atacama. Our affiliate, Servicios Integrales de Tránsitos y Transferencias S.A. (SIT), operates facilities for the shipment of products and the delivery of certain raw materials based on renewable concessions granted by Chilean regulatory authorities, provided that the facilities are used in accordance with the authorization granted and we pay an annual concession fee. The Port of Tocopilla terminal facilities have a weighted average age of 13.22 years and a gross book value of approximately US$167.9 million. The facilities include a truck weighing machine that confirms product entry into the port and transfers the product to distinct storage zones, a piezometer within the shipping system to carry out bulk product loaded onto ships, a crane with a 40-ton capacity for the loading of sealed product onto ships and a nitrate mixing facility.

The storage facilities consist of a system of six silos, with a total storage capacity of 55,000 metric tons, and a mixed storage area of open storehouses with a total storage capacity of approximately 250,000 metric tons. In addition, to fulfill future storage needs, we will continue to make investments in accordance with the investment plan outlined by management. The products are also put into bags at the Port of Tocopilla terminal facilities where the bagging capacity is established by two bag packaging machines, one for sacks and polypropylene FIBC big bags and one for FFS polyethylene. The products that are packaged in Tocopilla may be subsequently shipped at the same port or may also be consolidated into trucks or containers for its subsequent dispatch to clients by land or sea through containers from other ports, principally located in Antofagasta, Mejillones and Iquique.

For the transportation of bulk product, the transportation belt system extends across the coastline to deliver products directly to the hatches of bulk cargo ships. The nominal load capacity of this shipping system is 1,200 tons per hour. The transportation of packaged product is carried out utilizing the same bulk cargo ships using trailers without motors located in the dock and loaded by a crane with a 40 ton capacity from the Port of Tocopilla terminal. Thereafter, they are towed and unloaded using ship cranes to the respective warehouses.

We normally contract bulk cargo ships to transfer the product from the Port of Tocopilla terminal to our hubs around the world or to clients directly, who, in certain instances, use their own contracted vessels for delivery.

Tocopilla processes related to the reception, handling, storage and shipment of bulk/packaged nitrates produced at Coya Sur are certified by the third-party organization TÜV-Rheinland under the quality standard ISO 9001:2015.

Computer System

We have information systems and a management information system (Enterprise resource planning or ERP) to support the administrative business processes or support of the company: Finance, Accounting, Human Resources and Logistics (IT), this does not include production systems, plant operation, extraction and maintenance (OT). The ERP and main system is located in Chile; although each commercial office has its own ERP that is later consolidated in the central system in Chile.

The computer and information system is used mainly for finance, accounting, human resources, monitoring of supplies and inventories, billing, quality control, research activities and production process and maintenance control. The mainframe computing system is located at our offices in Santiago and our Chilean and international subsidiaries are interconnected with each other, through data links.

In addition, we have cloud technologies, which allow us to support new business processes and respond quickly and at low cost to changing conditions of our business and of the market.

In relation to information security and cybersecurity, we are executing a plan in accordance with the strategic objectives of the business to safeguard the most important assets defined in the corporate risk meetings. This implies making our users aware of the best use of processes and computing (awareness) and working to comply with standards.

Internal Controls

The preparation of mineral reserve and resource estimates is completed in accordance with our prescribed internal control procedures, which are designed specifically to ensure the reliability of such estimates presented herein. Annually, QPs and other employees review the estimates of mineral reserves and mineral resources, the supporting documentation, and compliance with applicable internal controls. Such controls employ management systems, standardized procedures, workflow processes, multi-functional supervision and management approval, internal and external reviews, reconciliations, and data security covering record keeping, chain of custody and data storage.

The internal controls for reserve and resource estimates also cover exploration activities, sample preparation and analysis, data verification, processing, metallurgical testing, recovery estimation, mine design and sequencing, and reserve and resource evaluations, with environmental, social and regulatory considerations. The quality assurance and control protocols over the assaying of drill hole samples are performed by reputable commercial laboratories following certification and accreditation programs established by the American Society for Testing and Materials (ASTM) or Australian National Association of Testing Authorities (NATA).

The reserve and resource estimates have inherent risks due to data accuracy, uncertainty from geological interpretation, mine plan assumptions, uncontrolled rights for mineral and surface properties, environmental challenges, uncertainty for future market supply and demand, and changes in laws and regulations. Management and QPs are aware of those risks that might directly impact the assessment of mineral reserves and resources. The current mineral reserves and resources are estimated based on the best information available and are subject to re-assessment when conditions change. Refer to Item 4A. “Risk Factors” for discussion of risks associated with the estimates of our mineral reserves and resources.

· the production and sale of specialty plant nutrients;

· the production and sale of iodine and its derivatives;

· the production and sale of lithium and its derivatives;

· the production and sale of potassium, including potassium chloride and potassium sulfate;

· the production and sale of industrial chemicals, principally industrial nitrates and solar salts; and

· the purchase and sale of other commodity fertilizers for use primarily in Chile.

We

sell our products through three primary channels: our own sales offices, a network of distributors and, in the case of our fertilizer products, through Yara International ASA’s (“Yara”) distribution network in countries where its presence and commercial infrastructure are larger than ours. Similarly, in those markets where our presence is larger, both our specialty plant nutrients and Yara’s are marketed through our offices.

Factors Affecting Our Results of Operations

Our results of operations substantially depend on:

· trends in demand for and supply of our products, including global economic conditions, which impact prices and sales volumes;

· efficient operations of our facilities, particularly as some of them run at production capacity;

83

· our ability to accomplish our capital expenditures program in a timely manner;

· the levels of our inventories;

· trends in the exchange rate between the U.S. dollar and Chilean peso, as a significant portion of the cost of sales is in Chilean pesos, and trends in the exchange rate between the U.S. dollar and the euro, as a significant portion of our sales is denominated in euros; and

· energy, logistics, raw materials, labor and maintenance costs.

Impact of Foreign Exchange Rates

We transact a significant portion of our business in U.S. dollars, which is the currency of the primary economic environment in which we operate and is our functional and presentation currency for financial reporting purposes. A significant portion of our costs is related to the Chilean peso as most of our operations occur in Chile, and therefore an increase or decrease in the exchange rate between the Chilean peso and the U.S. dollar affects our costs of production. Additionally, as an international company operating in Chile and several other countries, we transact a portion of our business and have assets and liabilities in Chilean pesos and other non-U.S. dollar currencies, such as the euro, the South African rand and the Mexican peso. As a result, fluctuations in the exchange rate of such currencies to the U.S. dollar may affect our financial condition and results of operations. See Note 24 to our consolidated financial statements.

We monitor and attempt to balance our non-U.S. dollar assets and liabilities position, including through foreign exchange contracts and other hedging instruments, to minimize our exposure to foreign exchange rate risk. As of December 31, 2021, for hedging purposes we had open contracts to buy U.S. dollars and sell Chinese Yuan for approximately US$207.6 million (CNY1,330.0 million), to sell Euros for approximately US$61.0 million (EUR52.75 million),and to sell South African rand for approximately US$35.8 million (ZAR 571.0 million), as well as forward exchange contracts to sell U.S. dollars and buy Chilean pesos for US$85.3 million (Ch$72,010 million). All of the UF 10.6 million outstanding bonds issued in the Chilean market were hedged with cross-currency swaps to the U.S. dollar for approximately US$420 million as of December 31, 2021.

In addition, we had open forward exchange contracts to buy U.S. dollars and sell Chilean pesos to hedge our time deposits in Chilean pesos for approximately US$263 million (Ch$221,816 million).

Results of Operations – 2021 compared to 2020

Revenues

Revenues increased by 57.5% to US$2,862.3 million in 2021 from US$1,817.2 million in 2020. The main factors that caused the increase in revenues and variations in different product lines are described below.

Lithium and Derivatives

Revenues from lithium and derivatives totaled US$936.1 million during the year ended December 31, 2021, an increase of 144.2% compared to the US$384.4 million for the year ended December 31, 2020. Set forth below are sales volume data for the specified years:

(in Th. MT)	2021		2020		% Change
Lithium and derivatives		101.1		64.6		56	%

During 2021, we believe total lithium market demand surpassed 500,000 metric tons, an increase of approximately 55% when compared to 2020. The lithium market was mainly driven by growth in the electric vehicle market, which we believe grew over 100% when compared to 2020, led by China representing about 50% of global sales.

85

Our sales volumes in the lithium and derivatives business line surpassed 101,000 metric tons during 2021, an increase of approximately 57% when compared to the previous year. We sold approximately 31,100 metric tons during the fourth quarter of 2021, with an average price of US$14,600.

Average prices in this business line increased 56.1% in 2021 compared to average prices during 2020, reaching approximately US$9,300/MT compared to average prices of approximately US$5,900/MT in 2020.

Specialty Plant Nutrition

Revenues from the specialty plant nutrition business line for the year ended December 31, 2021 totaled US$908.8 million, an increase of 29.5% compared to US$701.7 million reported for the year ended December 31, 2020.

Set forth below are sales volume data for the specified years by product category in this product line:

(in Th. MT)	2021		2020		% Change
Potassium nitrate and sodium potassium nitrate		643.6		575.2		12	%
Specialty blends		304.0		271.3		12	%
Other specialty plant nutrients (*)		174.9		164.4		6	%
Sodium nitrate		32.1		25.6		25	%

* Includes trading of other specialty fertilizers.

We believe demand growth in the agricultural potassium nitrate market increased approximately 4% when compared to 2020.

Our sales volumes during 2021 increased over 11% when compared to 2020, and average prices in this business lines increased over 16%. During the fourth quarter of 2021, prices surpassed US$940 per ton, related mostly to higher prices in the potassium nitrate markets, which have followed the positive trend observed in global potassium chloride prices and been impacted by lower production by some competitors. We saw our average prices increase approximately 39% when compared to prices reported during the same period of 2020.

Average prices in the specialty plant nutrition business line were US$466/MT in 2021, an increase of 61.9% compared to average prices of US$288/MT reported in 2020.

Iodine and Derivatives

Revenues from sales of iodine and derivatives during the year ended December 31, 2021 were US$437.9 million, an increase of 30.9% compared to US$334.7 million generated for the year ended December 31, 2020.

Set forth below are sales volume data for the specified years:

(in Th. MT)	2021		2020		% Change
Iodine and derivatives		12.3		9.7		27	%

Higher iodine revenues were the result of increased sales volumes during 2021 compared to 2020. Average prices in the business line increased

slightly

by 

2.8%, reaching US$36/kilogram in 2021 compared to US$35/kilogram in 2020.

86

Potassium

Potassium chloride and potassium sulfate revenues for the year ended December 31, 2021 totaled US$416.6 million, a 99.0% increase compared to the US$209.3 million reported for the year ended December 31, 2020.

(in Th. MT)	2021		2020		% Change
Potassium chloride and potassium sulfate		893.2		726.7		23	%

In 2021, we believe that the potassium chloride market reached approximately 71 million metric tons. Revenues in the potassium chloride and potassium sulfate business line during 2021 were impacted by higher average prices when compared to 2020 and higher sales volumes. Our sales volumes for potassium chloride and potassium sulfate reached approximately 893,000 metric tons. Average prices in the potassium chloride and potassium sulfate business line increased approximately 62% during 2021 when compared to 2020, reaching US$466/MT.

Industrial Chemicals

Industrial chemicals revenues for the year ended December 31, 2021 reached US$132.0 million, a 17.8% decrease compared to US$160.6 million for the year ended December 31, 2020.

Set forth below are sales volume data for the specified years by product category:

(in Th. MT)	2021		2020		% Change
Industrial chemicals		174.5		225.1		-22	%

Our lower revenues in industrial chemicals reflected lower sales volumes in the business line. We reported sales of approximately 99,000 metric tons of solar salts during year, lower than our original estimates as a result of delivery delays.

Other Products and Services

Revenues from sales of other commodity fertilizers and other income were US$30.8 million in 2021, an increase of 11.9% compared to US$27.6 million of revenues in 2020.

Cost of Sales

Our overall cost of sales increased 32.8% to US$1,772.2 million in 2021, which represented 61.9% of revenues, from US$1,334.3 million in 2020, which represented 71.2% of revenues. The main factors that caused the increase in cost of sales and variations in different product lines are described below.

Lithium and Derivatives

Lithium and derivatives cost of sales increased 66.6% to US$494.8 million in 2021 from US$297.0 million in 2020, primarily as a result of our increased sales volumes during 2021 compared to 2020.

87

Our costs of sales related to our lithium and derivatives business line fluctuate with our price of lithium as a result of our 2018 amendment of the lease agreement with Corfo. This agreement includes important amendments to the lease agreement and project agreement signed between Corfo and SQM in 1993. The main modifications became effective on April 10, 2018 and requires an increase in the lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. For lithium carbonate, the former rate of 6.8% on FOB sales was changed to the following structure of progressive rates based on the

final sale price (See Note 21.2 to our consolidated financial statements for the disclosure of lease payments made to Corfo for all periods presented.):

Price US$/MT Li2CO3	Lease payment rate
$0 - $4,000	6.8%
$4,000 - $5,000	8.0%
$5,000 - $6,000	10.0%
$6,000 - $7,000	17.0%
$7,000 - $10,000	25.0%
Over US$10,000	40.0%

Specialty Plant Nutrition

Specialty plant nutrition cost of sales increased 20.3% to US$646.9 million in 2021 from US$537.8 million in 2020, as a result of higher costs per ton of potassium nitrate The average cost of sales in the specialty plant nutrition business line was US$560/MT in 2021, higher than US$519/MT in 2020.

Iodine and Derivatives

Iodine and derivatives cost of sales increased 42.6% to US$240.3 million in 2021 from US$168.5 million in 2020. The average cost of sales in the iodine and derivatives business line was US$19.6/kilogram in 2021, an increase of 12.1% from US$17.5/kilogram in 2020.

Potassium

Potassium cost of sales increased 35.3% to US$253.1 million in 2021 from US$187.9 million in 2020, as a result of increased sales volumes. The average cost of sales in the potassium business line was US$283/MT in 2021, an increase from US$257/MT in 2020.

Industrial Chemicals

Industrial chemicals cost of sales decreased 8.4% to US$109.1 million in 2021 from US$119.1 million in 2020, as a result of decreased sales volumes in the business line. The average cost of sales in the industrial chemicals business line was US$652/MT in 2021, an increase of 18.2% from US$529/MT in 2020.

Gross Profit

Gross profit increased 125.8% to US$1,090.1 million in 2021, which represented 38.1% of revenues, from US$482.9 million in 2020, which represented 26.6% of revenues. As discussed above, this increase is attributable to the increase in revenues as a result of higher prices of lithium and derivatives, iodine and derivatives, specialty plant nutrients, industrial chemicals and potassium chloride and potassium sulphate and higher sales volumes of lithium and derivatives, iodine and derivatives, potassium chloride and potassium sulphate and specialty plant nutrients.

88

Other Income

Other income decreased 37.5% to US$19.6 million in 2021, which represented 0.7% of revenues, from US$26.9 million in 2020, which represented 1.5% of revenues.

Administrative Expenses

Administrative expenses increased 11.1% to US$118.9 million in 2021, which represented 4.1% of revenues, from US$107.0 million in 2020, which represented 5.9% of revenues.

Other Expenses

Other expenses decreased 39.2% to US$60.6 million in 2021, which represented 2.1% of revenues, from US$99.6 million in 2020, which represented 5.5% of revenues.

Other Gains (Losses)

Other losses were US$2.6 million in 2021, compared to losses of US$5.3 million in 2020.

Finance Income

Finance income decreased 67.0% to US$4.7 million in 2021, which represented 0.2% of revenues, from US$13.7 million in 2020, which represented 0.8% of revenues, due to lower interest rates earned on our investments.

Finance Expenses

Finance expenses increased 3.0% to US$84.6 million in 2021, which represented 0.3% of revenues, from US$82.2 million in 2020, which represented 4.5% of revenues, due to increased levels of

debt that we had outstanding during 2021 compared to 2020.

Equity Income of Associates and Joint Ventures Accounted for Using the Equity Method

Equity income of associates and joint ventures accounted for using the equity method increased 24.5% to US11.1 million in 2021, which represented 0.4% of revenues, from US$8.9 million in 2020, which represented 0.5% of revenues.

Foreign Currency Exchange Differences

Losses from foreign currency exchange differences amounted to US$17.2 million in 2021, which represented 0.6% of revenues, compared with a loss of US$4.4 million in 2020, which represented 0.2% of revenues. A significant portion of our costs is related to the Chilean peso as most of our operations occur in Chile. Because the U.S. dollar is our functional currency, we are subject to currency fluctuations. We seek to mitigate this impact through an active hedging program.

Profit Before Taxes

Profit before taxes increased by US$602.7 million, or 253%, to US$841.2 million in 2021 from US$238.5 million in 2020. This increase was primarily attributable to increase in revenues by US$1,045.1 million, partially offset by an increase in cost of sales by only US$437.9 million and an increase in administrative expenses by only US$11.9 million, as described above.

89

Income Tax Expense

Income tax expenses increased 254.8% to US$249.0 million in 2021, representing an effective tax rate of 29.6%, compared to US$70.2 million in 2020, representing an effective tax rate of 29.4%. The effective Chilean corporate tax rate was 27.0% during 2021 and 2020. 

Income tax increased as a result of higher taxable income reported in 2021 compared to 2020.

Profit for the Year

Profit for the year increased 251.8% to US$592.2 million in 2021 from US$168.4 million in 2020, primarily due to higher average prices in all of our business lines and higher sales volumes in the iodine, lithium and fertilizer business lines.

Results of Operations – 2020 compared to 2019

For a discussion of the comparison of our results of operations for the fiscal years 2020 and 2019, see “Part I, Item 5.A. Operating Results—Results of Operations – 2020 compared to 2019” of our Annual Report on Form 20-F for the fiscal year ended December 31, 2020 filed with the SEC on March 17, 2021.

5.B. Liquidity and Capital Resources

As of December 31, 2021, we had US$2,434.1 million of cash and cash equivalents and time deposits. In addition, as of December 31, 2021, we had US$498 million of unused uncommitted working capital credit lines.

Shareholders’ equity increased to US$3,216.0 million as of December 31, 2021 from US$2,162.6 million as of December 31, 2020. Our ratio of total liabilities to total equity (including non-controlling interest) on a consolidated basis decreased to 1.19 as of December 31, 2021 from 1.21 as of December 31, 2020.

We evaluate from time to time our cash requirements to fund capital expenditures, dividend payouts and increases in working capital, but we believe our working capital is sufficient for our present requirements. As debt requirements also depend on the level of accounts receivable and inventories, we cannot accurately determine the amount of debt we will require nor are our requirements typically seasonal.

The table below shows our cash flows for 2021, 2020 and 2019:

(in milli ons of US$)	2021			2020			2019
Net cash from operating activities		822.5			182.2			427.0
Net cash used in financing activities		1,206.5			(94.1	)		105.9
Net cash from (used in) investing activities		(1,006.9	)		(167.1	)		(485.5	)
Effects of exchange rate fluctuations on cash and cash equivalents		(16.1	)		(0.4	)		(14.9	)
Net increase (decrease) in cash and cash equivalents		(1,005.9	)		(79.4	)		(32.5	)

We operate a capital-intensive business that requires significant investments in revenue-generating assets. Our past growth strategies have included purchasing production facilities and equipment and the improvement and expansion of existing facilities. Funds for capital expenditures and working capital requirements have been obtained from net cash from operating activities, borrowing under credit facilities and issuing debt securities.

We believe that our capital expenditures for 2022 could reach approximately US$900 million focused on the maintenance of our production facilities in order to strengthen our ability to meet our production goals and to increase our production capacity, primarily related to lithium carbonate and lithium hydroxide capacity expansions and nitrates and iodine capacity in Chile and development of our lithium project in Australia. See “Item 4.A. History and Development of the Company—Capital Expenditure Program.”

90

Our other major use of funds is for dividend distributions.

I

n the consolidated statement of cash flows, we reported dividends paid of US$572 million and US$222 million during 2021 and 2020, respectively. For a disclosure of our 2021 dividend policy and payments, see “Item 8.A.8. Dividend Policy.”

The proposed dividend policy for 2022 is expected to be announced at the Annual Shareholders’ Meeting to be held on April 26, 2022.

As of December 31, 2021, we had US$2,434.1 million of cash and cash equivalents and time deposits. In addition, as of December 31, 2021, we had US$498 million of unused uncommitted working capital credit lines. Our Net Financial Debt to Adjusted EBITDA ratio was 0.2x as of December

31, 2021. Our next debt maturity that will require a significant cash payment is scheduled to occur in April 2023. We believe that our capital expenditures related to expansion and maintenance will require approximately US$900 million during 2022. We believe that our capital expenditures related to maintenance will require approximately US$120 million during 2022.

We have not entered into any transactions with unconsolidated entities whereby we have financial guarantees, retained or contingent interests in transferred assets, derivative instruments or other contingent arrangements that would expose us to material continuing risks, contingent liabilities, or any other obligations arising out of a variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to us or that engages in leasing, hedging or research and development services with us.

Our future cash position could be impacted by, among other things, an operational shutdown, unforeseen expenses, a decreased ability of our customers to pay us for products or services or lower average prices or sales volumes in our business lines. Demand growth, sales volumes and average prices in our business lines could continue to be impacted by the COVID-19 pandemic, and therefore could have an impact on our cash position which could lead to a material adverse effect on our business, financial condition and results of operations. See “Item 3.D. Risk Factors”

Financing Activities

Our current ratio, defined as current assets divided by current liabilities, decreased to 4.6 as of December 31, 2021 from 5.4 as of December 31, 2020. The following table shows key information about our outstanding long- and short-term debt as of December 31, 2021.

(1) UF denominated bonds are fully hedged to U.S. dollars with cross-currency swaps. Nota 14.4 b y d

As of December 31, 2021, we had total financial debt of US$2,588.7 million compared to US$1,899.5 million as of December 31, 2020. The total short-term debt as of December 31, 2021 was US$51.3million, and as of December 31, 2021 was US$69.0 million.

As of December 31, 2021, all of our long-term debt, including the current portion, was denominated in U.S. dollars, and all our UF-denominated bonds were hedged with cross-currency swaps to the U.S. dollar. The financial covenants related to our debt instruments include: (i) limitations on the ratio of NFD to equity (including non-controlling interest) on a consolidated basis, and (ii) minimum production assets. We believe that the terms and conditions of our debt agreements are standard and customary.

The following table shows the maturities of our nominal long-term debt by year as of December 31, 2021 (in millions of US dollars):

Maturity (1)	Amount
2022	13.3
2023	383.3
2024	13.3
2025	263.3
2026 and thereafter	1,885.2
Total	2,558.6

(1) Only the principal amount has been included. For the UF-denominated local bonds, the amounts presented reflect the real U.S. dollar obligation as of December 31, 2021 not including the effects of the cross-currency swaps that hedge these bonds to the U.S. dollar and which had, as of December 31, 2021, a market value of US$81.9 million against SQM.

On September 20, 2021, we issued and sold US$700 million principal amount of senior secured notes to qualified institutional buyers in the United States under Rule 144A under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and to investors outside the United States under Regulation S under the Securities Act. These notes have an annual interest rate of 4.250% and mature in 2051.

Environmental and Occupational Safety and Health Projects

We spent US$35.5 million on environmental, safety and health projects in 2021. We have budgeted approximately US$30.4 million in 2022 for environmental, safety and health projects. This amount forms part of the capital expenditure program discussed above.

Non-IFRS Financial Measures

This annual report makes reference to certain non-IFRS financial measures, namely EBITDA and adjusted EBITDA. These non-IFRS financial measures are not recognized measures under IFRS, do not have a standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies. Rather, these measures are provided as additional information to complement IFRS measures by providing further understanding of the Company’s results of operations from management’s perspective. Accordingly, they should not be considered in isolation nor as a substitute for analysis of our financial information reported under IFRS.

EBITDA represents Profit for the Year + Depreciation and Amortization Expenses + Finance Costs + Income Tax and Adjusted EBITDA is defined as EBITDA – Other income – Other gains (losses) - Share of Profit of associates and joint ventures accounted for using the equity method + Other expenses by function + Net impairment gains on reversal (losses) of financial assets – Finance income – Currency differences. We have included EBITDA and adjusted EBITDA to provide investors with a supplemental measure of our operating performance.

We believe EBITDA and adjusted EBITDA are important supplemental measures of operating performance because it eliminates items that have less bearing on our operating performance and thus highlights trends in our core business that may not otherwise be apparent when relying solely on IFRS financial measures.

EBITDA and adjusted EBITDA have important limitations as analytical tools. For example, EBITDA and adjusted EBITDA do not reflect (a) our cash expenditures, or future requirements for capital expenditures or contractual commitments; (b) changes in, or cash requirements for, our working capital needs; (c) the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debt; and (d) tax payments or distributions to our parent to make payments with respect to taxes attributable to us that represent a reduction in cash available to us. Although we consider the items excluded in the calculation of non-IFRS measures to be less relevant to evaluate our performance, some of these items may continue to take place and accordingly may reduce the cash available to us.

93

We believe that the presentation of the non-IFRS financial measures described above is appropriate. However, these non-IFRS measures have important limitations as analytical tools, and you should not consider them in isolation, or as substitutes for analysis of our results as reported under IFRS. Because of these limitations, we primarily rely on our results as reported in accordance with IFRS and use EBITDA and adjusted EBITDA only supplementally.

5.C. Research and Development, Patents and Licenses, etc.

One of the main objectives of our research and development team is to develop new processes and products in order to maximize the returns obtained from the resources that we exploit. Our research is performed by three different units, whose research topics cover all of the processes involved in the production of our products, including chemical process design, phase chemistry, chemical analysis methodologies and physical properties of finished products.

Our research and development policy emphasizes the following: (i) optimizing current processes in order to decrease costs and improve product quality through the implementation of new technology, (ii) developing higher-margin products from current products through vertical integration or different product specifications, (iii) adding value to inventories and (iv) using renewable energy in our processes.

94

Our research and development activities have been instrumental in improving our production processes and developing new value-added products. As a result, new methods of extraction, crystallization and finishing products have been developed. Technological advances in recent years have enabled us to improve process efficiency for the nitrate, potassium and lithium operations, improve the physical quality of our prilled products and reduce dust emissions and caking by applying specially designed additives to our products handled in bulk. Our research and development efforts have also resulted in new, value-added markets for our products. One example is the use of sodium nitrate and potassium nitrate as thermal storage in solar power plants.

We have patented several production processes for nitrate, iodine and lithium products. These patents have been filed mainly in the United States, Chile and in other countries when necessary. The patents used in our production processes include Chilean patent No. 47,080 for iodine (production of spherical granules of chemicals that sublime) and Japanese patent No. 4,889,848 for nitrates (granular fertilizers).

5.D. Trend Information

Our revenues increased 57.5% to US$2,862.3 million in 2021 from US$1,817.2 million in 2020. Gross profit reached US$1,090.1 million (38.1% of revenues) in 2021, higher than US$482.9 million (26.6% of revenues) recorded in 2020. Profit attributable to controlling interests increased 255.9% to US$585.5 million in 2021 from US$164.5 million in 2020.

In January 2020, the World Health Organization deemed COVID-19 a global pandemic. In March 2020, the Chilean Ministry of Health (

Ministerio de Salud

) declared a nationwide State of Emergency. In response to the spread of COVID-19, the Chilean government has closed its borders for entry by non-resident foreigners for a specified period of time, prohibited the docking of cruise ships at Chilean ports, imposed quarantines on certain neighborhoods of the capital of Santiago and other cities and imposed a nationwide curfew. These measures have not impacted imports or exports to or from Chile.

As a precaution, our management has implemented several additional measures to help reduce the speed at which COVID-19 may spread in our Company, including measures to mitigate the spread in the workplace, significant reductions in employee travel and a mandatory quarantine for people who have arrived from high-risk destinations, in consultation with governmental and international health organization guidelines, and will continue to implement measures consistent with the evolving COVID-19 situation. However, we did not see a material impact on our operations related to COVID-19 during 2021. While the global impacts of the COVID-19 pandemic are constantly changing, international financial markets have reflected the uncertainty associated with the slowdown of the global economy and the potential impact if businesses, workers, customers and others are prevented or restricted from conducting business activities due to quarantines, business closures or other restrictions imposed by businesses or governmental authorities in response to the COVID-19 outbreak.

Revenues from lithium and derivatives totaled US$936.1 million during the twelve months ended December 31, 2021, an increase of 144.2% compared to the US$383.4 million for the twelve months ended December 31, 2020. During 2021, Our sales volumes in the lithium and derivatives business line surpassed 101,000 metric tons, an increase of approximately 57% when compared to the previous year. Additionally, our average prices in the lithium and derivatives business line reached approximately US$9,300, an increase of 56.1% when compared to 2020. We sold approximately 31,100 metric tons during the fourth quarter, with an average price of US$14,600. Accordingly, we believe that sales volumes and average prices in this business line could be materially higher in 2022 when compared to 2021, reaching close to 140,000 metric tons and that our average prices could be materially higher.

We remain particularly optimistic about the long-term growth of the lithium market. For this reason, we expect to increase our lithium carbonate and lithium hydroxide capacity significantly in the coming year. We expect our installed capacity of lithium carbonate and lithium hydroxide in Chile to reach approximately 180,000 and 30,000 metric tons, respectively, during the first half of 2022. In addition, we recently announced that we will further increase our capacity to 210,000 and 40,000 metric tons of lithium carbonate and lithium hydroxide, respectively, in 2023.

95

Revenues from sales of iodine and derivatives during the twelve months ended December 31, 2021 were US$437.9 million, an increase of 30.9% compared to US$334.7 million generated for the twelve months ended December 31, 2020. During 2021, global demand for iodine had a significant recovery compared to 2020, even exceeding the demand levels seen before the COVID-19 pandemic. Main drivers of this increase were seen in the X-ray contrast media market, which demand grew by 14-15% compared to 2020, mainly due to worldwide growth in the healthcare industry spending during the year and increased accessibility to these types of treatments in emerging economies. This strong recovery led to a strong pricing environment during the year, with prices increasing over 11% in the fourth quarter 2021 when compared to the third quarter. As a result of tight supply/demand equilibrium, we are expecting the upward pricing trend to continue during 2022. We believe that demand growth in 2022 could be around 1%. We believe average prices in 2022 could be significantly higher.

Revenues from the SPN business line for the twelve months ended December 31, 2021 totaled US$908.8 million, an increase of 29.5% compared to $701.7 million reported for the twelve months ended December 31, 2020. The specialty plant nutrition business line remains an important segment within our diverse portfolio and we believe demand growth in the agricultural potassium nitrate market increased approximately 4% when compared to 2020. Our sales volumes during 2021 increased over 11% when compared to 2020, and average prices in this business lines increased over 16%. During the fourth quarter of 2021, prices surpassed US$940 per ton, related mostly to higher prices in the potassium nitrate markets, which have followed the positive trend observed in global potassium chloride prices and been impacted by lower production by some competitors. We saw our average prices increase approximately 40% when compared to prices reported during the same period of 2020. We believe that prices could remain at this level or higher during the first half of 2022.

Potassium chloride and potassium sulfate revenues for 2021 totaled US$416.6 million, a 99.0% increase compared to the US$209.3 million reported for the twelve months ended December 31, 2020. We estimate that demand in 2021 reached approximately 71 million metric tons. During the first months of 2022, we have seen strong demand growth, however due to current macroeconomic factors it is difficult to estimate the overall potassium market growth this year. Global prices in the potassium chloride market increased significantly and rapidly throughout 2021, especially in the fourth quarter 2021 when our average prices during the fourth quarter reached almost US$685 per metric ton. We believe that average prices during 2022 will be significantly higher than the average prices of US$466 per metric ton reported during 2021.

For the Chairman and the Vice Chairman, the fee amounted to UF 800 and UF 700 per month respectively. For the remaining six directors, the fee amounted to UF 600 per month. In addition, the directors received variable compensation (in Chilean pesos) based on a profit-sharing program approved by the shareholders.

Because he joined the Board in December 2021, Ashley Ozols did not receive any compensation for 2021.

For the year ended December 31, 2021, the aggregate compensation paid to our 127 members of management based in Chile was US$31.6 million. We do not disclose to our shareholders or otherwise make available to the public information as to the compensation of our individual executive officers.

We maintain incentive programs for our employees based on individual performance, company performance and short-term indicators. We provide executives with an annual and a long-term bonus plan. Their incentives are based on target achievement, individual contribution to the Company’s operating results, and the Company’s performance. SQM also operates a compensation plan designed to retain its executives by providing bonuses linked to the Company’s share price.

102

As of December 31, 2021, we had a provision related to all of the incentive programs in the aggregate of US$27.1 million.

We do not maintain any pension or retirement programs for the members of the Board of Directors or our executive officers in Chile.

6.C. Board Practices

Information regarding the period of time each of SQM’s current Directors has served in his office is provided in the discussion of each member of the Board of Directors above in “Item 6.A. Directors and Senior Managers.”

The date of expiration of the term of the current Board of Directors is April 2022. The contracts of our executive officers are indefinite.

The members of the Board of Directors are remunerated in accordance with the information provided above in “Item 6.B. Compensation.” There are no contracts between SQM, or any of its subsidiaries, and the members of the Board of Directors providing for benefits upon termination of their term.

Directors’ Committee – Audit Committee

As required by Chilean Law, during 2021, we had a Directors’ Committee (

Comité de Directores

) composed of three Directors, which performs the functions of an audit committee. Under the NYSE corporate governance rules, the audit committee of a U.S. company must perform the functions detailed in the NYSE Listed Company Manual Rules 303A.06 and 303A.07. Non-U.S. companies are required to comply with Rule 303A.06 but are not required to comply with Rule 303A.07.

Since April 25, 2019, our Directors’ Committee has been comprised of three Directors: Messrs. Georges de Bourguignon Arndt, Laurence Golborne Riveros and Alberto Salas Muñoz. Each of the three members meets the NYSE independence and Chilean independence requirements for audit committee members. Mr. Salas holds the position of Chairman of the Directors’ Committee.

During 2021, the Directors’ Committee (the “Committee”) analyzed (i) the Company’s Unaudited Financial Statements and Reports; (ii) the Company’s Audited Financial Statements and Reports; (iii) the Reports and proposals of external auditors, accounts inspectors and independent risk rating agencies for the Company; (iv) the proposal to SQM’s Board of Directors about the external auditors and independent rating agencies that the Board could recommend to the respective shareholders’ meeting for their subsequent appointment; (v) the tax and other services, other than audit services, provided by the Company’s external auditors and its subsidiaries in Chile and abroad; (vi) the remuneration and compensation plans for the Company’s main executives; (vii) the Company’s risk matrix; (viii) the activity related to the Company's compliance program; (ix) the report on internal control of the Company and (x) the various matters referred to in the Chapter titled “Directors’ Committee” included in SQM’s Financial Statements at December 31, 2021.

103

Regarding the above, the Committee:

(a) Examined the information regarding the financial statements of SQM for the 2021 fiscal year and the report issued thereon by the external auditors of SQM, Similarly, it also examined the Company’s Interim Consolidated Financial Statements for the 2021 fiscal year.

(b) Proposed to the Company’s Board of Directors the names of the External Auditors and the Independent Credit Rating Agencies for SQM and the Company’s Board of Directors, in turn, suggested their appointment to the respective Annual Ordinary Shareholders Meeting of SQM. The Company’s Board of Directors approved said suggestions and the Shareholders’ Meeting also ratified them.

(c) Examined and approved the remuneration system and the compensation plans for the Company’s employees and senior executives.

The Committee also (i) authorized the contracting by the Company of various consulting services with PwC on non-audit related matters, (ii) reviewed the expenses of the Company's CEO, (iii) reviewed the reports from the Company’s internal audit and risk and compliance areas, and (iv) examined the information presented by the External Auditors.

The Committee issued the Annual Management Report referred to in the Chilean Corporations Act.

During 2021, the Company did not enter into related party transactions which require to follow the requirements and procedures established in title XVI of the Corporations Act, therefore the Committee was not required to examine information regarding related party transactions, but did review a potential transaction that was not entered into by the Company.

On April 23, 2021, the Annual General Shareholders’ Meeting of SQM approved an operational budget for the Committee; the operational budget is equivalent to the sum of the annual remunerations of the members of the Committee and US$250,000. The activities carried out by the Committee, as well as the expenses incurred by it, are disclosed at the General Shareholders Meeting.

Article 50 bis of the Chilean Corporations Act states that the Committee should consist of three Directors, of which at least one member should preferably be independent from the controller (i.e., any person or entity who “controls” the company for Chilean law purposes), if any, and that their functions be remunerated.

Comparative Summary of Differences in Corporate Governance Standards

The following table provides a comparative summary of differences in corporate governance practices followed by us under our home-country rules and those applicable to U.S. domestic issuers pursuant to Section 303A of the New York Stock Exchange (NYSE) Listed Company Manual.

Listed Companies that are foreign private issuers, such as SQM, are permitted to follow home country practices in lieu of the provisions of Section 303A, except such companies are required to comply with the requirements of Section 303A.06, 303A.11 and 303A.12(b) and (c).

303A.02	No director qualifies as “independent” unless the Board of Directors affirmatively determines that the director has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company). In addition, a director is not independent if: (i) The director is, or has been within the last three years, an employee of the listed company, or an immediate family member is, or has been within the last three years, an executive officer, of the listed company. (ii) The director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from the listed company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service). (iii) (A) The director is a current partner or employee of a firm that is the listed company’s internal or external auditor; (B) the director has an immediate family member who is a current partner of such a firm; (C) the director has an immediate family member who is a current employee of such a firm and personally works on the listed company’s audit; or (D) the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the listed company’s audit within that time.

A director would not be considered independent if, at any time, within the last 18 months he or she: (i) Maintained any relationship of a relevant nature and amount with the company, with other companies of the same group, with its controlling shareholder or with the principal officers of any of them or has been a director, manager, administrator or officer of any of them; (ii) Maintained a family relationship with any of the members described in (i) above; (iii) Has been a director, manager, administrator or principal officer of non-profit organizations that have received contributions from (i) above; (iv) Has been a partner or a shareholder that has had or controlled, directly or indirectly, 10% or more of the capital stock or has been a director, manager, administrator or principal officer of an entity that has provided consulting or legal services for a relevant consideration or external audit services to the persons listed in (i) above; (v) Has been a partner or a shareholder that has had or controlled, directly or indirectly, 10% or more of the capital stock or has been a director, manager, administrator or principal officer of the principal competitor, supplier or clients.

6.D. Employees

As of December 31, 2021, we had 6,081 permanent employees, 410 of whom were employed outside of Chile. The average tenure of our permanent employees is approximately 6.6 years.

	As of December 31,
	2021		2020		2019
Employees in Chile		5,671		5,080		5,274
Employees outside of Chile		410		427		467
Total employees		6,081		5,507		5,741

As of December 31, 2021, 66% of our permanent employees in Chile were represented by 20 labor unions, which represent their members in collective negotiations with us. Compensation for unionized personnel is established in accordance with the relevant collective bargaining agreements. The terms of such agreements currently in effect are three years, and expiration dates of such agreements vary from agreement to agreement. Under these agreements, employees receive a salary according to a scale that depends upon job function. Unionized employees also receive certain benefits provided by law and certain benefits provided under the applicable collective bargaining agreement, which vary depending upon the terms of the collective agreement, such as scholarships, holiday bonuses and additional health death and disability benefits, among others.

In addition, we own all of the equity of Institución de Salud Previsional Norte Grande Limitada (“Isapre Norte Grande”), which is a health care organization that provides medical services primarily to our employees, and of Sociedad Prestadora de Servicios de Salud Cruz de Norte S.A. (“Prestadora”), which is a hospital in María Elena. We make contributions to Isapre Norte Grande and to Prestadora in accordance with Chilean laws and the provisions of our various collective bargaining agreements, but we are not otherwise responsible for their liabilities.

Non-unionized employees receive individually negotiated salaries, benefits provided for by law and certain additional benefits which we provide.

We provide housing and other facilities and services for employees and their families at the María Elena site.

We do not maintain any pension or retirement programs for our Chilean employees. Most workers in Chile are subject to a national pension law, adopted in 1980, which establishes a system of independent pension plans that are administered by the corresponding Pension Fund Administrator (Sociedad Administradora de Fondos de Pensiones). We have no liability for the performance of any of these pension plans or any pension payments to be made to our employees. We do, however, sponsor staff severance indemnities plans for our employees and employees of our Chilean subsidiaries whereby we commit to provide a lump sum payment to each employee at the end of his/her employment, whether due to death, termination, or resignation.

Over 93% of our employees are employed in Chile, of which approximately 66% were represented by 20 labor unions as of December 31, 2021. As of December 31, 2021, all collective bargaining agreements had been renegotiated in advance. We are exposed to labor strikes and illegal work stoppages by both our own employees and our independent contractors’ employees that could impact our production levels in both our own plants and our independent contractors’ plants. If a strike or illegal work stoppage occurs and continues for a sustained period of time, we could be faced with increased costs and even disruption in our product flow that could have a material adverse effect on our business, financial condition and results of operations.

6.E. Share Ownership

We do not grant stock options or other arrangements involving the capital of SQM to directors, managers or employees. For more information on the shareholdings of current directors and executive officers, see “Item 6. Directors, Senior Management and Employees—Directors and Senior Management.”

Tianqi Extrajudicial Agreement with the FNE

In August

 2018, after an investigation by the FNE in connection with the proposed acquisition by Tianqi of 23.77% of the Company’s then-outstanding total shares, Tianqi and the FNE entered into an extrajudicial agreement (the “Extrajudicial Agreement”) which implemented certain restrictive measures in order to (i) maintain the competitive conditions of the lithium market, (ii) mitigate the risks described in the Extrajudicial Agreement and (iii) limit Tianqi’s access to certain information of the Company and its subsidiaries, which are defined as sensitive under the Extrajudicial Agreement (“Sensitive Information”) (collectively, the “Purpose”).  Pursuant to the Extrajudicial Agreement, Tianqi agreed that, among other things:

· Tianqi will not nominate any of its directors, executives or employees to the SQM Board of Directors;

· Tianqi and the directors nominated by it will not influence or intervene for the benefit of Tianqi and prejudice the interests of SQM;

· The directors nominated by Tianqi will not participate nor will they be part of any committees, the management or other decision-making bodies related to lithium of SQM or of any companies controlled by SQM, unless nominated by independent directors;

· Tianqi will inform the FNE of any agreement in the lithium market, with Albemarle and/or SQM, prior to its execution;

· Tianqi will notify the FNE of any event from which it acquires control or decisive influence in SQM;

· Tianqi will disassociate any director, executive or employee appointed by third parties, who assumes a position described above in SQM;

· Tianqi will not request access to Sensitive Information from SQM;

· The directors nominated by Tianqi will not disclose Sensitive Information of SQM;

· The directors nominated by Tianqi will personally bind themselves to the obligations assumed by Tianqi with the FNE; and

· Tianqi will report to the FNE the appointments and periodic compliance with its obligations.

The restrictions will remain in place for a period of six years.

During the approval process for the Extrajudicial Agreement before the FNE, the Company expressed its concerns to the Chilean Antitrust Court regarding the measures contained in the Extrajudicial Agreement, including that (i) it could not effectively resolve the risks that Tianqi and the FNE sought to mitigate, (ii) the restrictions are not correctly oriented to avoid the access to Sensitive Information that, in the possession of a competitor, could damage the Company and the proper functioning of the market and (iii) it could contradict the Chilean Corporations Act. The Extrajudicial Agreement was approved in October 2018 by the Chilean Antitrust Court. A copy of the Extrajudicial Agreement, in Spanish, has been made publicly available on the Company’s website at

www.sqm.com

and is also available on the FNE’s website at

http://www.fne.gob.cl

In light of the Company’s concerns regarding the limitations of the Extrajudicial Agreement measures, the Company’s Board of Directors deemed it necessary to adopt measures aimed at achieving the purpose of the Extrajudicial Agreement, avoiding greater points of contact between Sensitive Information and Tianqi, to complement the Extrajudicial Agreement and adopted a protocol for the presentation and use of Sensitive Information (as defined in the Extrajudicial Agreement) on September 30, 2019. See “Item 10.B. Memorandum and Articles of Association—Board Protocol for Presentation and Use of Sensitive Information” below.

The Company believes that approximately 51.64% of its Series A common shares and 28.94% of its Series B common shares were beneficially held in Chile as of March 1, 2022. Approximately 1,188 record holders were in Chile as of March 1, 2022.

Series A and Series B common shares have the same economic rights (i.e., both series are entitled to share equally in any dividends declared on the outstanding stock) and voting rights at any shareholders meeting, whether ordinary or extraordinary, with the exception of the election of the Board, in which the Series A shareholders elect seven members and the Series B shareholders elect one member.

109

Additionally, Series B common shares cannot exceed 50% of SQM’s issued, subscribed and paid shares; shareholders of at least 5% of this Series may call an Ordinary or Extraordinary Shareholders’ Meeting; and the director elected by this Series may request an extraordinary Board meeting without the authorization of the Chairman of the Board. These conditions will remain in effect until 2043. Under our By-laws, the maximum individual voting power personally and/or in representation of other shareholders per Series is limited to 37.5% of the subscribed shares of each Series with voting rights and 32% of the total subscribed shares with voting rights, with any excess being deducted from the number of shares such shareholder may vote. To calculate these percentages, shares that belong to the voting shareholder’s related persons must be added. In addition, the director elected by the Series B shareholders cannot vote in the election of the Chairman of the Board if a tie vote has occurred in the prior voting process. As of March 1, 2022, there were 142,819,552 Series A common shares and 142,818,904 Series B common shares outstanding.

7.B. Related Party Transactions

Title XVI of the Chilean Corporations Act regulates transactions with related parties for publicly held corporations and its related parties.

Articles 146 to 149 of the Chilean Corporations Act requires that our transactions with related parties (i) have as their purpose to contribute to SQM’s interests (ii) be on price, terms and conditions similar to those customarily prevailing in the market at the time of their approval and (iii) satisfy the requirements and procedures established by the Chilean Corporations Act. Violation of such articles may also result in administrative or criminal sanctions and civil liability may be sought by SQM, shareholders or interested third parties that suffer losses as a result of such violations.

In addition, article 89 of the Chilean Corporations Act requires that transactions between affiliates, subsidiaries or related parties of a closed-stock company, such as some of SQM’s main affiliates and subsidiaries, shall also be on terms similar to those customarily prevailing in the market. Directors and executive officers of companies that violate article 89 are liable for losses resulting from such violations.

With respect to SQM, transactions with related parties include negotiations, proceedings, contracts or transactions involving SQM and its directors, managers and officers, and their spouses and relatives, and other companies and persons connected to the abovementioned parties or mentioned in the By-laws or by the Directors’ Committee. Such transactions may only be carried out if (i) their objective is to contribute to SQM’s interests and if their price, terms and conditions conform to prevailing market prices, terms and conditions at the time of their approval and (ii) they satisfy the requirements and procedures established by the Chilean Corporations Act. Such requirements include, among others:

· that the transaction be informed to the Directors' Committee and to the Board of Directors prior to its execution;

· that the Board of Directors, excluding any Directors involved in the transaction, approves the transaction with an absolute majority of its members, or, if an absolute majority is not feasible, with a unanimous vote by the Directors not involved in the transaction, or, if neither of these options is available, that an Extraordinary Shareholders' Meeting be held and that shareholders representing 2/3 of the outstanding shares with voting rights approve the transaction. In the latter case, prior to the meeting, the shareholders must be provided with a report by an independent evaluator and with statements by the directors as to whether or not such transaction is in SQM's interest;

110

· that the grounds for the decision and for the exclusion be recorded in the respective minutes of the Board meeting; and

· that the agreement and the names of the directors who approved the same be reported at the next shareholders' meeting. Infractions will not affect the validity of the transaction but they will grant SQM or its shareholders the right to demand that the related party committing such infraction refund the amount equivalent to the benefits received by such party in the transaction to SQM, and that such party indemnify for any corresponding damages.

However, the Board of Directors has authorized the following transactions with related parties to be carried out without following such requirements and procedures, as long as such authorization is obtained in advance: (a) transactions wherein the amount of the transaction is not significant or (b) transactions that, according to the policy on customary transactions with related parties, are considered normal based on SQM’s business activities or (c) transactions carried out between legal entities wherein SQM holds at least a 95% ownership interest in the counterpart.

Accounts receivable from and payable to related companies are stated in U.S. dollars and accrue no interest. Other than the above, transactions are made under terms and conditions that are similar to those offered to unrelated third parties. We further believe that we could obtain from third parties all raw materials now being provided by related parties that are not our affiliates. The provision of such raw materials by new suppliers could initially entail additional expenses.

In each case, terms and conditions vary depending on the transaction pursuant to which it was generated.

In March 2022, the Company adopted a Conflict of Interest Policy which is applicable to all directors, executives and employees of the Company. Under the policy, conflicts of interest may arise where there are family relationships, ownership relationships, management relationships or other situations where the director, executive or employee’s impartiality may be diminished or whose decisions may be contrary to the duty of probity that governs their actions. The policy provides procedure for the resolution of the conflict of interest. For directors, the procedures involve the Company’s compliance officer agreeing with the Directors’ Committee to propose a resolution for approval by the Board of Directors. In the event that a director has an interest or participates in a transaction with related parties that constitutes a conflict of interest under the policy, the related party transaction procedures under the Chilean Corporations Act described above would apply in lieu of the policy. Directors are required to present a declaration of conflict of interest within a month following their appointment as a director and each time a new conflict of interest not previously declared is identified.

The Company regularly enters into business arrangements with related parties, principally its joint ventures and associates, which are described in Note 8 to our Consolidated Financial Statements.

Legal Proceedings

Class Actions

In October 2015, a consolidated class action lawsuit was brought against the Company in the United States District Court for the Southern District of New York, alleging violations of the U.S. securities laws in connection with the subject matter of the investigations of the payments described above. The complaint alleged that certain statements made by the Company, principally in the Company’s SEC filings and press releases, were materially false and/or misleading in violation of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder. Specifically, the complaint challenges certain of the Company’s statements concerning its compliance with applicable laws and regulations; the effectiveness of its internal controls; its adoption of a code of ethics consistent with SEC requirements; its revenues and taxes owed; and its compliance with applicable accounting standards. The complaint also alleged that the Company made inadequate disclosures concerning the status of the Corfo litigation described below. The lead plaintiff sought damages of an undetermined amount to recover the economic losses allegedly suffered by the class as a result of the challenged statements.

On January 10, 2018, the lead plaintiff filed a motion to certify a class consisting of all persons who purchased SQM ADSs between June 30, 2010 and March 18, 2015.

On December 11, 2020, the Company and the lead plaintiff, the Council of the Borough of South Tyneside, acting in its capacity as the Administering Authority of the Tyne and Wear Pension Fund, filed before the United States District Court of the Southern District of New York a Stipulation of Settlement of the class action litigation. The class action settlement resolves the claims by class plaintiffs relating to alleged noncompliance with the securities laws and regulations in the United States in connection with certain disclosures made by the Company. Pursuant to the Stipulation of Settlement, SQM paid US$62.5 million. On April 26, 2021, the final settlement was approved by the

District Court.

SQMNA Litigation

In October 2010, the City of Pomona, California, named SQM North America Corporation (“SQMNA”) and SQM as defendants in an action filed in the California Superior Court for Los Angeles County (the “Pomona Case”). In this matter, the plaintiff seeks damages for alleged groundwater contamination from the use of defendants’ fertilizer products. The plaintiff subsequently withdrew its lawsuit against SQM. The case was removed to the U.S. District Court for the Central District of California and on June 10, 2015, the jury rejected the lawsuit against SQMNA, and the plaintiff filed an appeal which was granted by the Ninth Circuit Court of Appeals. The matter was then remanded to the District Court for a complete retrial.

On May 17, 2018, after a new trial in the District Court, a jury ruled in favor of SQMNA. On September 8, 2021, a jury found in favor of Pomona and against SQMNA on a single cause of action for strict products liability under California law. The jury found that Pomona’s damages were US$48,128,378. On January 27, 2022, the District Court entered judgment for Pomona in the amount of US$48,128,378. On February 24, 2022, SQMNA filed a motion for new trial, which was refiled to address a purported procedural issue on February 25, 2022; the District Court has not ruled on the merits of the motion. On February 25, 2022, SQMNA filed a notice of appeal of the District Court judgment to the Ninth Circuit Court of Appeals.

112

In October 2010, the City of Lindsay, California, named SQM and SQMNA as defendants in an action filed in the California Superior Court for Tulare County. In this matter, the plaintiff seeks damages for alleged groundwater contamination from the use of defendants’ fertilizer products. This case was removed to the U.S. District Court for the Eastern District of California and is pending in the trial court. The proceeding has been suspended, pending the outcome of the Pomona Case. SQMNA and SQM intend to vigorously defend this action.

Deferred Prosecution Agreement

On January 13, 2017, the Company and the DOJ reached agreement on the terms of a DPA that would resolve the DOJ’s inquiry based on alleged violations of the books and records and internal controls provisions of the Foreign Corrupt Practices Act in connection with certain payments made by SQM between the tax years 2009 to 2015 for services that may not have been properly supported or that may not have been necessarily to generate corporate income. Among other terms, the DPA called for the Company to pay a monetary penalty of US$15,487,500 and engage a compliance monitor for a term of two (2) years. On January 19, 2021, after successful completion of the three (3) year term of the DPA and the DOJ’s motion to dismiss, all charges against the Company were dismissed.

Other Matters

In addition, various lawsuits, claims and proceedings, other than those specifically disclosed above, have been or may be instituted or asserted against the Company, relating to the conduct of the company’s business, including those pertaining to mining, civil, tort, commercial, labor and regulatory matters, among others. Although the outcome of other litigation cannot be predicted with certainty, and some lawsuits, claims or proceedings may be disposed of unfavorably to the Company, our management believes the disposition of such other pending matters will not have a material effect on the company’s business, financial condition, results of operations or cash flows.

8.A.8.

Dividend Policy

As required by Chilean law and regulations, our dividend policy is decided upon from time to time by our Board of Directors and is announced at the Annual General Shareholders’ Meeting, which is generally held in April of each year. Shareholder approval of the dividend policy is not required. However, each year the Board must submit the declaration of the final dividend or dividends in respect of the preceding year, consistent with the then-established dividend policy, to the Annual General Shareholders’ Meeting for approval. As required by the Chilean Corporations Act, unless otherwise decided by unanimous vote of the holders of issued shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated net income for that year (determined in accordance with CMF regulations), unless and to the extent the Company has a deficit in retained earnings.

On March 30, 2021, the Board of Directors, agreed to recommend to the shareholders the payment of a final dividend representing 30% of the 2020 net income. The dividend payment was presented for consideration at the Annual General Shareholders’ Meeting held on April 23, 2021. The amount of the final dividend approved by shareholders at the Annual General Shareholders’ Meeting held on April 23, 2021 was US$0.18752 per share; the amount of US$0.17092 per share was deducted from the definitive dividend as it had been already paid in a form of an interim dividend during 2020. The balance, in the amount of US$0.01660 per share, was paid and distributed to Company’s shareholders on May 7, 2021.

SQM's dividend policy for 2021, reported at the Shareholders' Meeting held on April 23, 2021 and modified as a result of the approval of the distribution and payment of a special dividend equivalent to US$1.40037 per share charged to the retained earnings of the Company (the “Special Dividend”) by the Extraordinary Shareholders' Meeting held on December 22, 2021, included the following:

(a) Distribute and pay to the corresponding shareholders, a percentage of the net income that shall be determined per the following financial parameters as a final dividend ( dividendo definitivo ):

(i) 100% of the 2021 net income, when the following financial parameters are met: (a) that the total current assets, divided by the total current financial liabilities is equal to or greater than 2.5 times, and (b) the sum of the total current liabilities and total non-current liabilities, excluding both cash and cash equivalents and other current financial assets, divided by the total equity is equal to or less than 0.85 times.

(ii) 80% of the 2021 net income, when the following financial parameters are met: (a) that the total current assets, divided by the total sum of the total current financial liabilities is equal to or greater than 2.0 times, and (b) the total sum of the current liabilities and total non-current liabilities, excluding both cash and cash equivalents and other current financial assets divided by the total equity is equal to or less than 0.95 times.

113

(iii) 60% of the 2021 net income, when the following financial parameters are met: (a) that the total current assets, divided by the total sum of the total current financial liabilities is equal to or greater than 1.5 times, and (b) the total sum of the current liabilities and total non-current liabilities, excluding both cash and cash equivalents and other current financial assets divided by the total equity is equal to or less than 1.05 times.

(iv) If none of the foregoing financial parameters are met, the Company shall distribute and pay 50% of the 2021 net income in favor of the respective shareholders as a final dividend.

(b) Distribute and pay only two interim dividends during 2021, which will be charged against the aforementioned final dividend and that will be charged to the retained earnings reflected in the consolidated financial statements as of March 31, 2021 and as of June 30, 2021, respectively, the percentage distributed shall be determined per the financial parameters expressed in  paragraph ( a) above.

On May 19, 2021 and August 18, 2021, the Company's Board of Directors agreed to distribute and pay an interim dividends equivalent to US$0.23797 per share and US$0.31439 per share, respectively, both charged to the Company's 2021 retained earnings. These amounts were paid in their equivalent in Chilean pesos according to the official exchange rate on May 28, 2021 and on September 1, 2021, respectively (the “Interim Dividends”).

(c) The Board of Directors will not approve the payment of other interim dividends charged against the 2021 net income.

(d) At the ordinary general shareholders’ meeting that will be held in 2022, the Board of Directors will propose a final dividend pursuant to the percentages in financial parameters described in in paragraph (a) above after deducting the Special Dividend and Interim Dividends previously paid. If the amount is equal to or less than the amount of the sum of the Special Dividend and the Interim Dividends, then no additional amount will be distributed and the Interim Dividends will be understood to be paid as a definitive dividend. In any case, the final dividend may not be less than the mandatory minimum dividend that corresponds in accordance with Chilean law or the Company bylaws.

(e) If there is an excess of net income in 2021, this may be retained and assigned or allocated for financing its own operations, to one or more investment projects of the Company, notwithstanding a future distribution of special dividends ( dividendos eventuales ) charged to the retained earnings previously approved at the shareholders’ meeting, or the possible and future capitalization of all or part of the latter.

(f) The payment of additional dividends ( dividendos adicionales ) is not considered.

It is expressly stated that the dividend policy described above corresponds to the intention of the Board of Directors, and the compliance of it shall depend on the net income that the Company ultimately obtains, as well as the results of projections that could periodically impact the Company, or to the existence of determined conditions that may affect it, as applicable. If the dividend policy exposed by the Board of Directors suffers a substantial change, the Company must communicate it as an essential fact (

hecho esencial

).

114

On December 22, 2021, the Extraordinary Shareholders' Meeting approved the payment of a special dividend equivalent to US$1.40037 per share, charged to the retained earnings of the Company. This amount was paid on December 30, 2021 in its equivalent in Chilean pesos according to the official exchange rate on December 28, 2021.

The dividend policy proposal for 2022 is expected to be announced at the Annual General Shareholders’ Meeting to be held on April 26, 2022.

We generally declare dividends in U.S. dollars (but may declare dividends in Chilean pesos) and pay such dividends in Chilean pesos. When a dividend is declared in U.S. dollars, the exchange rate to be used to convert the dividend into Chilean pesos is decided by the shareholders at the meeting that approves the dividend, which has usually been the Observed Exchange Rate on the date the dividend is declared. In the case of interim dividends, the exchange rate to be used is the Observed Exchange Rate published a minimum of five business days before the payment date.

The amount and timing for payment of dividends is subject to revision from time to time, depending upon our then current level of sales, costs, cash flow and capital requirements, as well as market conditions. Accordingly, there can be no assurance as to the amount or timing of declaration or payment of dividends in the future. Any change in dividend policy would ordinarily be effective for dividends declared in the year following adoption of the change, and a notice as to any such change of policy must be filed with Chilean regulatory authorities and would be publicly available information.

Dividends

Each Series A common share and Series B common share is entitled to share equally in any dividends declared on the outstanding capital stock of SQM.

The following table shows the U.S. dollar equivalent of dividends per share and per ADS paid in each of the years indicated, based on the Observed Exchange Rate for the date on which the dividend was declared.

Dividends payable to holders of ADSs will be paid net of conversion expenses of the Depositary and will be subject to Chilean withholding tax, currently imposed at the rate of 35% (subject to credits in certain cases).

As a general requirement, a shareholder who is not a resident of Chile must register as a foreign investor under one of the foreign investment regimes contemplated by Chilean law to have dividends, sale proceeds or other amounts with respect to its shares remitted outside Chile through the Formal Exchange Market. Under the Foreign Investment Contract, the Depositary, on behalf of ADR holders, will be granted access to the Formal Exchange Market to convert cash dividends from Chilean Pesos to U.S. dollars and to pay such U.S. dollars to ADS holders outside Chile net of taxes, and no separate registration of ADS holders is required.

118

Directors

As stated in article 9 of the Company’s By-laws, the Company has eight Directors. One of the directors must be “independent” as such term is defined in article 50 bis of the Chilean Corporations Act. Moreover, the possession of shares is not a condition necessary to become a director of the Company.

As stated in article 10 of the Company’s By-laws, the term of the directors is of three years and they can be reelected indefinitely; thus, there is no age limit for their retirement.

The Company’s By-laws, in articles 16 and 16 bis, essentially establish that the transactions in which a director has a material interest must comply with the provisions set forth in articles 136 and 146 to 149 of the Chilean Corporations Act and the applicable regulations of the Chilean Corporations Act.

The Board of Directors duties are remunerated, as stated in article 17 of the Company’s By-laws, and the amount of that compensation is fixed yearly by the Ordinary Shareholders’ Meeting. Therefore, directors can neither determine nor modify their compensation.

Directors cannot authorize Company loans on their behalf.

The Board of Directors must provide shareholders and the public with sufficient, reliable and timely information pertaining to the Company’s legal, economic and financial situation, as required by the Law or the CMF. The Board of Directors must adopt the appropriate measures in order to avoid the disclosure of such information to persons other than those persons who should possess such information as a result of their title, position or activity within the Company before such information is disclosed to shareholders and the public. The Board of Directors must treat business dealings and other information about the Company as confidential until such information is officially disclosed. No Director may take advantage of the knowledge about commercial opportunities that he has obtained through his position as Director.

Independent Directors and Directors Committee

According to Chilean Law, SQM must appoint at least one Independent Director and a Directors’ Committee, due to the fact that (a) the Company has a market capitalization greater than or equal to UF 1,500,000 and (b) at least 12.5% of the Company’s shares with voting rights are held by shareholders who, on an individual basis, control or possess less than 10% of such shares.

Persons who have not been involved in any of the circumstances described in the Law at any time during the preceding 18 months are considered independent. Candidates for the position of Independent Director must be proposed by shareholders representing 1% or more of the Company’s shares, at least 10 days prior to the date of the shareholders’ meeting that has been called in order to elect the Directors. No less than two days prior to the respective shareholders’ meeting, the candidate must provide the Chief Executive Officer with a sworn statement indicating that he: (a) accepts his candidacy for the position of Independent Director; (b) does not meet any of the conditions that would prevent him from being the Independent Director; (c) is not related to the Company, the other companies of the group to which the Company belongs, the controller of the Company, or any of the Company’s officers in such a way that would deprive a sensible person of a reasonable degree of autonomy, interfere with his ability to perform his duties objectively and effectively, generate a potential conflict of interest, or interfere with his independent judgment; and (d) assumes the commitment to remain independent as long as he holds the position of Director.

119

The Directors’ Committee shall have the following powers and duties: (a) to examine the reports of the external auditors, the balance sheet and other financial statements presented by the Company’s managers or liquidators to its shareholders and issue an opinion about the same prior to their submission for the approval of the shareholders; (b) to propose to the Board of Directors the external auditors and risk rating agencies to be proposed to the shareholders at the respective shareholders’ meeting. In the event that an agreement cannot be reached, the Board of Directors shall formulate its own suggestion, and both options shall be submitted for shareholder consideration at such shareholders’ meeting; (c) to examine the information relating to operations referred to in articles 146 to 149 of the Chilean Corporations Act and to prepare a report about such operations. A copy of such report shall be sent to the Board of Directors, and such report must be read at the Board Meeting called for the purpose of approving or rejecting the respective operation or operations; (d) to examine the remuneration system and compensation plans for the Company’s management, officers and employees; (e) to prepare an annual report on its activities, including its main recommendations to the shareholders; (f) to inform the Board of Directors about whether or not it is advisable to hire the external audit firm to provide non-audit services where the audit firm is not prohibited from providing such services because the nature of the same could pose a threat to the audit firm’s independence; and (g) any other issues indicated in the Company’s By-laws or authorized by a shareholders’ meeting or the Board of Directors.

The Directors’ Committee shall be comprised of three members, with at least one independent member. In the event that more than three Directors have the right to form part of the Committee, these same Directors shall unanimously determine who shall make up the Committee. In the event that an agreement cannot be reached, the Directors who were elected with a greater percentage of votes by shareholders controlling or possessing less than 10% of the Company’s shares shall be given priority. If there is only one Independent Director, this Director shall name the other members of the Committee among the other Directors who are not independent. Such other members of the Committee shall have all of the rights associated with such position. The members of the Committee shall be compensated for their role. The amount of their remuneration shall be set annually at the General Shareholders’ Meeting, and it may not be less than the remuneration set for the Company Directors, plus an additional 1/3 of that amount. The General Shareholders’ Meeting shall determine a budget for the expenses of the Committee and its advisors. Such budget may not be less than the sum of the annual remunerations of the Committee members. The Committee may need to hire professional advisory services in order to carry out its duties in accordance with the abovementioned budget. The proposals made by the Committee to the Board of Directors that are not accepted by the latter must be reported to the shareholders’ meeting prior to the vote by shareholders on the corresponding matter or matters. In addition to the responsibilities that are associated with the position of Director, the members of the Committee are jointly and severally liable for any damages they cause in performing their duties as such to the shareholders and to the Company.

Shares

Dividends are annually distributed to the Series A and Series B shareholders of record on the fifth business day prior to the date for payment of the dividends. The By-laws do not specify a time limit after which dividend entitlement lapses, but Chilean regulations establish that after five years, unclaimed dividends are to be donated to the fire department.

Article 5 of the Company’s By-laws establishes that Series B shares may in no case exceed 50% of SQM’s issued, outstanding and paid stock. SQM Series B shares have a restricted right to vote as they can only elect one director of the Company, regardless of their capital stock’s share. Series B shares have the right to call for an Ordinary or Extraordinary Shareholders’ Meeting when the shareholders of at least 5% of the Series B issued shares request so and for an Extraordinary Board of Directors Meeting without the Chairman’s authorization when it is requested by the director elected by the shareholders of the Series B shares. Series A shares have the option to exclude the director elected by Series B shareholders from the voting process in which the Chairman of the Board is to be elected, if there is a tie in the first voting process. However, subject to the second transitory article of the Company’s By-Laws, articles 31 and 31 bis of the Company’s By-laws establish that in General Shareholders’ Meetings each shareholder will have a right to one vote for each share he owns or represents and (a) that no shareholder will have the right to vote for himself or on behalf of other shareholders of the same Series A or Series B shares representing more than 37.5% of the total outstanding shares with right to vote of each Series and (b) that no shareholder will have the right to vote for himself or on behalf of other shareholders representing more than 32% of the total outstanding shares with a right to vote, with any excess being deducted from the number of shares such shareholder may vote. In calculating a single shareholder’s ownership of Series A or B shares, the shareholder’s stock and those pertaining to third parties related to them are to be added.

120

The second transitory article provides as follows:

“Throughout the period running from the date of the extraordinary shareholders’ meeting at which this transitory article is incorporated, and December 31, 2030, the restriction against voting on behalf of more than 37.5% of any series of shares in the Company, established in Article 31 hereof, shall be subject to the following exception, applicable only to the election of board members by means of Series A shares in the Company: If two or more persons, regardless of whether or not they are related parties to each other (the incoming shareholders), act prior to December 31, 2030 such as to acquire a sufficient number of Series A shares to allow them to hold voting powers for the selection of directors of the Company amounting to more than 37.5% of that series, then any registered shareholder or group of shareholders holding more than 37.5% of all Series A shares in the Company shall be entitled to vote for the selection of directors of the Company amounting to whichever is less, between a number of the Series A shares that are held (i) by existing shareholders as of that date, and (ii) by the incoming shareholders with voting rights. Similarly, if for any reason a registered shareholder in the Company as of the date hereof who holds more than 37.5% of Series A shares in the company between the date hereof and December 31, 2030, comes to hold more voting shares for the selection of directors of the Company than the votes allocated for holding 37.5% of said Series A shares, either through a joint action agreement with other shareholders, including existing shareholders, or by any other means, then any other shareholder or group of shareholders in the Company that is not a related party to the same and holds more than 37.5% of all voting Series A shares in the Company, including both existing and incoming shareholders, shall be entitled to vote for the selection of directors of the Company in accordance with whichever number of Series A shares in the Company is the lesser, between (i) the number held by this shareholder or group of shareholders, and (ii) the existing shareholder may have the capacity to vote in excess of the restriction amounting to 37.5% of said shares.”

121

Article 5 bis of the Company’s By-laws establishes that no person may directly or by means of related third persons concentrate more than 32% of the Company’s total shares with right to vote.

Each Series A share and Series B share is entitled to share equally in the Company’s profits, i.e., they have the same rights on any dividends declared on the outstanding shares of SQM.

The Company By-laws do not contain any provision relating to (a) redemption provisions (b) sinking funds or (c) liability to capital calls by the Company.

As established in article 103 of the Chilean Corporations Act, a company subject to the supervision of the CMF may be liquidated in the following cases:

(a) Expiration of the duration term, if any, as established in its By-laws;

(b) All the shares end up in the possession of one individual for more than ten continuous days;

(c) By agreement of an Extraordinary Shareholders Meeting;

(d) By abolition, pursuant to applicable laws, of the decree that authorized its existence;

(e) Any other reason contemplated in its By-laws.

Article 40 of the Company’s By-laws states that in the event of liquidation, the shareholders’ meeting will appoint a three-member receiver committee that will have the authority to carry out the liquidation process. Any surplus will be distributed equally among the shareholders.

The only way to change the rights of the holders of the SQM shares is by modifying its By-laws, which can only be carried out by an Extraordinary Shareholders’ Meeting, as established in article 28 of the Company By-laws.

Shareholders’ Meetings

Article 29 of the Company’s By-laws states that the call to a shareholders’ meeting, either Ordinary or Extraordinary, will be by means of a highlighted public notice that will be published at least three times, and on different days, in the newspaper of the legal address determined by the shareholders’ meeting, and in the way and under the conditions indicated by the regulations. Additionally, a notice will be sent by mail to each shareholder at least fifteen days prior to the date of the Meeting, which shall include a reference of the matters to be addressed at the meeting. However, those meetings with the full attendance of the shares with right to vote may be legally held, even if the foregoing formal notice requirements are not met. Notice of any shareholders’ meeting shall be delivered to the CMF at least fifteen days in advance of such meeting.

Any holder of Series A and/or Series B shares registered in the Company’s shareholder registry on the fifth business day prior to the date of the meeting will have a right to participate at that meeting

Article 67 of the Chilean Corporations Act provides that decisions made at Extraordinary Shareholders’ Meeting on the following matters require the approval of 2/3 of the outstanding shares with voting rights: (1) transformation or division of the Company and its merger with another company; (2) modification of the Company’s term of duration, if any; (3) early dissolution of the Company; (4) change of the corporate domicile; (5) capital decrease; (6) approval of contributions and estimation of non-cash assets; (7) modification of powers reserved for Shareholders Meetings or limitations on powers of the Board of Directors; (8) reduction in the number of members of the Board of Directors; (9) disposal of 50% or more of the Company’s assets; formulation or modification of any business plan exceeding the above percentage; disposal of 50% or more of an asset belonging to a subsidiary that represents at least 20% of the Company’s assets and disposal of shares of the referred subsidiary such that the parent company would lose its position as controller of the same; (10) method in which profits are distributed; (11) granting of real or personal guarantees as sureties for third-party obligations that exceed 50% of the Company assets, except for subsidiaries, in which case approval of the Board of Directors shall suffice; (12) acquisition of own shares as set forth in articles 27A and 27B of the said law; (13) other matters indicated in the By-laws; (14) amendment of the Company By-laws as a result of errors in the constitution process and amendments in the By-laws involving one or more of the matters stated in the preceding numbers; (15) forced sale of shares carried out by the controller who would acquire more than 95% of the Company’s shares in a tender offer, and (16) approval or ratification of proceedings or contracts with related parties in accordance with the provisions of articles 44 and 147 of the Chilean Corporations Act.

122

Amendments to the By-laws that are intended to create, modify, defer or suspend preferential rights shall be approved by 2/3 of the shares of the affected Series.

The transformation of the Company, the merger of the same, the disposal of assets referred to in number (9) above, the constitution of guarantees set forth in number (11) above, the constitution of preferences or the increase, postponement or decrease of the existing preferences, the reparation of formal nullities incurred in the By-laws and the possession of more than 95% of the Company’s shares and other matters contemplated in the Law or in the By-laws, confer “withdrawal rights.”

Shareholders Restrictions

There are no restrictions on ownership or share concentration, or limiting the exercise of the related right to vote, by local or foreign shareholders other than those discussed under “—Shares”

Change in Control

The Company By-laws provide that no shareholder may hold more than 32% of the Company’s shares, unless the By-laws are modified at an Extraordinary Shareholders’ Meeting. Moreover, on December 12, 2000, the Chilean Government published the

Ley de Oferta Pública de Acciones

(“Public Share Offering Law”) or (OPA law) that seeks to protect the interests of minority shareholders of open stock corporations in transactions involving a change in control, by requiring that the potential new controller purchase the shares owned by the remaining shareholders either in total or pro rata. The law applies to those transactions in which the controlling party would receive a material premium price compared with the price that would be received by the minority shareholders.

There are three conditions that would make it mandatory to operate under the OPA law:

1) When an investor wants to take control of a company’s stock.

2) When a controlling shareholder holds two-thirds of the company’s stock. If such shareholder buys one more share, it will be mandatory to offer to acquire the rest of the outstanding stock within 30 days of surpassing that threshold.

3) When an investor wants to take control of a corporation, which, in turn, controls an open stock corporation that represents 75% or more of the consolidated assets of the former corporation.

Parties interested in taking control of a company must (i) notify the company of such intention in writing, and notify its controllers, the companies controlled by it, the CMF and the markets where its stocks are traded and (ii) publish a highlighted public notice in two newspapers of national circulation at least 10 business days prior to the date of materialization of the OPA.

Board Protocol for Presentation and Use of Sensitive Information

On December 5, 2018, Inversiones TLC SpA, a subsidiary of Tianqi, acquired 62,556,568 Series A shares of the Company, representing approximately 23.77% of the total shares issued by SQM. In connection with the acquisition, Tianqi entered into and Extrajudicial Agreement with the FNE with respect to the implementation of certain measures to maintain competitive market conditions and mitigate any risks identified in the transaction, having as a fundamental principle the limitation of access to commercially sensitive information of SQM by Tianqi. For a description of the Extrajudicial Agreement, see “Item 7.A. Major Shareholders — Tianqi Extrajudicial Agreement with the FNE.” Before this acquisition, and after the approval of this transaction by the Chilean Antitrust Court, the Company’s Board of Directors deemed it necessary to adopt measures aimed at achieving the purpose of the Extrajudicial Agreement, avoiding greater points of contact between Sensitive Information and Tianqi, to complement the Extrajudicial Agreement. On January 23, 2019, the Board of Directors approved a protocol for the presentation and use of Sensitive Information (as defined in the Extrajudicial Agreement), which was amended on April 15, 2019 in response to comments received from the CMF. The amendment was subsequently approved by the Board on September 30, 2019.

10.C. Material Contracts

The Company, during the normal course of business, has entered into different contracts, some of which have been described herein, related to its production, commercial and legal operations. We believe all of these contracts are standard for this type of industry, and none of them is expected to have a material effect on the Company’s results of operations. . For a description of the Lease Agreement and Project Agreement with Corfo providing for our rights to exploit mineral resources in the Salar de Atacama, see “Item 3.D. Risk Factors, “Our inability to extend it renew the mineral exploitation rights relating to the Salar de Atacama concession, upon which our business is substantially dependent, beyond their current expiration date in December 2030 could have a material adverse effect on our business, financial condition and results of operations.” and “Item 4.D. Property, Plant and Equipment.”

10.D. Exchange Controls

The Central Bank of Chile is responsible for, among other things, monetary policies and exchange controls in Chile. Appropriate registration of a foreign investment in Chile permits the investor access to the Formal Exchange Market. Foreign investments can be registered with the Foreign Investment Committee under Decree Law No. 600 of 1974, as amended, or can be registered with the Central Bank of Chile under the Central Bank Act, Law No 18,840 of October 1989. The Central Bank Act is an organic constitutional law requiring a “special majority” vote of the Chilean Congress to be modified. Effective January 1, 2016, Decree Law No. 600 was repealed by Article 9 of the 2014 Tax Reform. Therefore, foreign investments made on or after January 1, 2016 cannot be registered with the Foreign Investment Committee.

Our 1993, 1995, 1998 and 2021 capital increases were carried out under and subject to the then current legal regulations, whose summary is hereafter included:

A

Convención Capítulo XXVI del Título I del Compendio de Normas de Cambios Internacionales

or Compendium of Foreign Exchange Regulations of the Central Bank of Chile the “Foreign Investment Contract”, was entered into and among the Central Bank of Chile, our Company and the Depositary pursuant to Article 47 of the Central Bank Act and to Chapter XXVI of the Compendium of Foreign Exchange Regulations of the Central Bank of Chile, “Chapter XXVI,” which addresses the issuance of ADSs by a Chilean company.  Absent the Foreign Investment Contract, under applicable Chilean exchange controls, investors would not be granted access to the Formal Exchange Market for the purposes of converting from Chilean pesos to U.S. dollars and repatriating from Chile amounts received in respect to deposited Series B shares, or Series B shares withdrawn from deposit on surrender of ADSs (including amounts received as cash dividends and proceeds from the sale in Chile of the underlying Series B shares and any rights arising therefrom). The following is a summary of the material provisions contained in the Foreign Investment Contract. This summary does not purport to be complete and is qualified in its entirety by reference to Chapter XXVI and the Foreign Investment Contract.

124

Under Chapter XXVI and the Foreign Investment Contract, the Central Bank of Chile has agreed to grant to the Depositary, on behalf of ADS holders, and to any investor not residing or not domiciled in Chile who withdraws Series B shares upon delivery of ADSs (such Series B shares being referred to herein as “Withdrawn Shares”) access to the Formal Exchange Market to convert Chilean pesos to U.S. dollars (and remit such U.S. dollars outside of Chile) in respect of the Withdrawn Shares, including amounts received as (a) cash dividends, (b) proceeds from the sale in Chile of Withdrawn Shares, or from shares distributed because of the liquidation, merger or consolidation of the Company, subject to receipt by the Central Bank of Chile of a certificate from the holder of such shares (or from an institution authorized by the Central Bank of Chile) that such holder’s residence and domicile are outside Chile and a certificate from a Chilean stock exchange (or from a brokerage or securities firm established in Chile) that such shares were sold on a Chilean Exchange, (c) proceeds from the sale in Chile of preemptive rights to subscribe for additional Series A and Series B shares, (d) proceeds from the liquidation, merger or consolidation of the Company and (e) other distributions, including without limitation those resulting from any recapitalization, as a result of holding Withdrawn Shares. Transferees of Withdrawn Shares will not be entitled to any of the foregoing rights under Chapter XXVI unless the Withdrawn Shares are redeposited with the Depositary. Investors receiving Withdrawn Shares in exchange for ADSs will have the right to redeposit such shares in exchange for ADSs, provided that the conditions to redeposit described hereunder are satisfied.

Chapter XXVI provided that access to the Formal Exchange Market in connection with dividend payments will be conditioned upon certification by the Company to the Central Bank of Chile that a dividend payment has been made and any applicable tax has been withheld. Chapter XXVI also provided that access to the Formal Exchange Market in connection with the sale of Withdrawn Shares or distributions thereon will be conditioned upon receipt by the Central Bank of Chile of certification by the Depositary that such shares have been withdrawn in exchange for ADSs and receipt of a waiver of the benefit of the Foreign Investment Contract with respect thereto until such Withdrawn Shares are redeposited.

Chapter XXVI and the Foreign Investment Contract provide that a person who brings certain types of foreign currency into Chile, including U.S. dollars, to purchase Series B shares with the benefit of the Foreign Investment Contract must convert it into Chilean pesos on the same date and has 5 banking business days within which to invest in Series B shares in order to receive the benefits of the Foreign Investment Contract. If such person decides within such period not to acquire Series B shares, he can access the Formal Exchange Market to reacquire foreign currency, provided that the applicable request is presented to the Central Bank within 7 banking business days of the initial conversion into Chilean pesos. Series B shares acquired as described above may be deposited for ADSs and receive the benefits of the Foreign Investment Contract, subject to receipt by the Central Bank of Chile of a certificate from the Depositary that such deposit has been effected and that the related ADSs have been issued and receipt by the Custodian of a declaration from the person making such deposit waiving the benefits of the Foreign Investment Contract with respect to the deposited Series B shares.

Access to the Formal Exchange Market under any of the circumstances described above is not automatic. Pursuant to Chapter XXVI, such access requires approval of the Central Bank of Chile based on a request presented through a banking institution established in Chile. The Foreign Investment Contract will provide that if the Central Bank of Chile has not acted on such request within seven banking days, the request will be deemed approved.

Under current Chilean law, foreign investments abiding by the Foreign Investment Contract cannot be changed unilaterally by the Central Bank of Chile. No assurance can be given, however, that additional Chilean restrictions applicable to the holders of ADSs, the disposition of underlying Series B shares or the repatriation of the proceeds from such disposition could not be imposed in the future, nor can there be any assessment of the duration or impact of such restrictions if imposed.

125

As of April 19, 2001, Chapter XXVI of Title I of the

Compendio de Normas de Cambios Internacionales

of the Central Bank of Chile was eliminated and new investments in ADSs by non-residents of Chile, are now governed by Chapter XIV of the

Compendio de Normas de Cambios Internacionales

of the Central Bank of Chile. This was made with the purpose of simplifying and facilitating the flow of capital to and from Chile. According to the new regulations, such investments must be carried out through Chile’s Formal Exchange Market and only reported to the Central Bank of Chile.

The Central Bank is also responsible for controlling incurrence of loan obligations to be paid from Chile and by a Chilean borrower to banks and certain other financial institutions outside Chile. Chapter XIV establishes what type of loans, investments, capital increases and foreign currency transactions are subject to the current Chapter XIV framework. Foreign currency transactions related to foreign loans must be performed through the Formal Exchange Market, and such transactions and the subsequent modifications of original loans must be properly informed to the Central Bank. Transactions prior to April 19, 2001, will continue to be regulated by the previous legal framework, except in cases where an express request has been presented to the Central Bank resigning previous rights to be regulated by the provisions of Chapter XIV. This summary does not purport to be complete and is qualified in its entirety by reference to the provisions of Chapter XIV.

As of December 31, 2021, we had five series of bonds issued in the international markets under Rule 144A/Regulation S in the principal amounts of US$250 million, US$250 million, US$300 million US$450 million and US$700 million.

Any purchases of U.S. dollars in connection with payments on these loans will occur with the Formal Exchange Market. There can be no assurance, however, that restrictions applicable to payments in respect to the loans could not be imposed in the future, nor can there be any assessment of the duration or impact of such restrictions if imposed.

10.E. Taxation

Material Chilean Tax Considerations

The following describes the material Chilean income tax consequences of an investment in SQM ADSs by an individual who is not domiciled or resident in Chile or any legal entity that is not organized under the laws of Chile and does not have a permanent establishment located in Chile, a (“foreign holder”). This discussion is based upon Chilean income tax laws presently in force, including Ruling No. 324 (1990) of the Chilean Internal Revenue Service and other applicable regulations and rulings. The discussion is not intended as tax advice to any particular investor, which can be rendered only in light of that investor’s particular tax situation.

Under Chilean law, provisions contained in statutes such as tax rates applicable to foreign holders, the computation of taxable income for Chilean purposes and the manner in which Chilean taxes are imposed and collected may only be amended by another statute. In addition, the Chilean tax authorities issue rulings and regulations of either general or specific application and interpret the provisions of Chilean tax law. Chilean tax may not be assessed retroactively against taxpayers who act in good faith relying on such rulings, regulations and interpretations, but Chilean tax authorities may change said rulings, regulations and interpretations prospectively.

126

Cash Dividends and Other Distributions

On September 29, 2014, the Tax Reform was published, introducing significant changes to the Chilean taxation system and strengthening the powers of the SII to control and prevent tax avoidance. Subsequently, on February 8, 2016, Law No. 20,899 that simplifies the income tax system and modifies other legal tax provisions was published. On February 24, 2020, Law No. 21,210 to modernize the tax legislation was published. As a result of these reforms, open stock corporations like SQM are subject to the partially integrated shareholder income tax regime. The corporate tax rate applicable to us increased to a rate of 27% in 2018 and remains the same today.

Under the partially integrated system, the tax burden for dividends distributed by companies to their final shareholders (

i.e.

, taxpayers of the Additional Tax (non-residents) or the Complementary Global Tax (resident natural persons)) allows only a portion of the Chilean corporate income tax paid by the company to be applied as a credit against the tax payable on dividends, unless the shareholder is resident in a country that has a treaty to prevent double taxation with Chile in effect or such treaty was signed before January 1, 2020, even if not yet in effect. In such case, 100% of the Chilean corporate income tax paid by the company may be applied as a credit against the shareholder's taxes payable on dividends.

As a result of the foregoing, foreign shareholders who are residents of a jurisdiction without a tax treaty will be subject to a higher effective tax rate on dividends than residents of jurisdictions with tax treaties.

In the case of U.S. investors, a tax treaty between the United States and Chile was signed prior to January 1, 2020, such that shareholders resident in the United States can allocate 100% of the Chilean corporate tax paid by the Company against the Additional Tax levied on dividends.

Cash dividends paid by the Company with respect to the shares, including shares represented by ADSs held by a U.S. Holder (as defined below), will be subject to a 35% Chilean withholding tax, which is withheld and paid by the Company (the “Withholding Tax”). The effective rate of Withholding Tax imposed on dividends attributed to 2021 earnings of the Company and distributed during the same period was 23.90412%.

Capital Gains

Gains from the sale or other disposition by a foreign holder of ADSs outside Chile will not be subject to Chilean taxation. The deposit and withdrawal of the shares in exchange for ADRs will not be subject to any Chilean taxes.

The tax basis of the shares received in exchange for ADSs (repatriation) will be the acquisition value of the shares. The Series B shares exchanged for ADSs are valued at the highest price at which they trade on the Chilean Stock Exchange on the date of the exchange or on either of the two business days preceding the exchange. Consequently, the conversion of ADSs into the shares and the immediate sale of such shares at a price equal to or less than the highest price for Series B shares on the Chilean Stock Exchange on such dates will not generate a gain subject to Chilean taxation.

The general tax regime for the higher value or gain recognized in a transfer of shares (as opposed to sales or exchanges of ADSs that represent those shares) in force as of this date, is subject to both the First Category Tax and the Additional Tax. The amount of the First Category Tax may be credited against the amount of the Additional Tax.

However, the profit obtained from the disposal in the stock exchange or in a public offer governed by the Securities Law of shares of open corporations with a high presence in the stock market is not subject to income tax in Chile. Law No. 20,448 establishes that the shares must also have been acquired after April 19, 2001, in a local stock exchange authorized by the CMF, within the process known as the public offering of ordinary shares governed by the Chilean Securities Market Law, in an initial public offering of common shares resulting from the formation of a corporation or a capital increase thereof, in an exchange of convertible securities subject to public offering, or in the redemption of shares of mutual funds. According to Ruling No. 224 (2008) of the Chilean Internal Revenue Service, the shares received by exchange of ADRs are also considered as "acquired in a stock exchange" if the respective ADRs have been acquired in a stock exchange authorized by the CMF (for example, the London Stock Exchange, the New York Stock Exchange or the Madrid Stock Exchange). Common shares are considered to have a high presence in the stock market when: (a) they are registered in the Security Registry, (b) they are registered in the Chilean Stock Exchange, and (c) they have an adjusted stock market presence equal to or higher than 25%.

127

As of June 19, 2001, the highest value obtained in the disposal of shares listed on a stock exchange are also exempt from income tax in Chile, when the disposal is carried out by "foreign institutional investors", such as mutual funds and pension funds, provided that the sale is made in a local stock exchange authorized by the CMF, or in accordance with the provisions of the Securities Market Law (Law No. 18,045). To qualify as foreign institutional investors, the aforementioned entities must be formed outside of Chile, not have a domicile in Chile, and must be an "investment fund" under Chilean tax law.

On February 2, 2022, Law No. 21,420 was published, which, among other matters, introduced modifications to the tax regime applicable to the sale on the stock exchange or in a process of public offering of shares of corporations with stock market presence, established in article 107 of the Chilean Income Tax Law. Pursuant to this amendment, the highest value or gain obtained will be subject to a single 10% tax. This tax must be withheld by the intervening purchaser or stockbroker, at a rate of 10% calculated on the highest value, if the latter is known on the date of payment of the price, remittance, credit to account or provision, or , with a rate of 1% on the total price, without any deduction, if the highest value is not known on that same date.

For purposes of determining the highest value subject to the tax at a rate of 10%, the amendment introduced by Law No. 21,420 provides that taxpayers with domicile or residence in Chile may consider as acquisition and/or contribution value, at their option:

a) The official closing price of the respective securities, as of December 31 of the year of acquisition, considering first the oldest securities according to their date of acquisition, which may be proposed by the Chilean tax authority in the income statement of the corresponding tax year by virtue of the information that said authority has at its disposal. Said proposal will not release the taxpayer from supplementing or adjusting the corresponding information in accordance with the general rules; or

b) The value of acquisition and/or contribution in accordance with the general regulations established in the Income Tax Law.

Regarding taxpayers without domicile or residence in Chile, for purposes of determining the highest value subject to the single tax with a rate of 10%, they must consider the value of acquisition and/or contribution in accordance with letter b) above."

This modification will take effect on September 1, 2022 and will apply to disposals made after that date.

Other Chilean Taxes

No Chilean inheritance, gift or succession taxes apply to the transfer or disposition of the ADSs by a foreign holder, but such taxes generally will apply to the transfer at death or by gift of the shares by a foreign holder. No Chilean stamp, issue, registration or similar taxes or duties apply to foreign holders of ADSs or shares.

Withholding Tax Certificates

Upon request, the Company will provide to foreign holders appropriate documentation evidencing the payment of Chilean withholding taxes.

128

Material U.S. Federal Income Tax Considerations

The following discussion summarizes the material U.S. federal income tax consequences to U.S. Holders (defined below) arising from ownership and disposition of the Series A shares and the Series B common shares, together the “shares”, and the ADSs. The discussion which follows is based on the U.S. Internal Revenue Code of 1986, as amended, the “Code,” the Treasury regulations promulgated thereunder, and judicial and administrative interpretations thereof, all as in effect and available on the date hereof. These authorities are subject to change, possibly with retroactive effect, which could affect the continued validity of this summary. In addition, the summary assumes that the depositary’s activities are clearly and appropriately defined so as to ensure that the U.S. federal income tax treatment of ADSs will be identical to the U.S. federal income tax treatment of the underlying shares.

The discussion that follows is not intended as tax advice to any particular investor and is limited to investors who will hold the shares or ADSs as “capital assets” within the meaning of Section 1221 of the Code and whose functional currency is the U.S. dollar. The summary does not address the tax treatment of holders that may be subject to special U.S. federal income tax rules, such as insurance companies, tax-exempt organizations, financial institutions, persons who are subject to the alternative minimum tax, persons who are broker-dealers in securities or foreign currency or dealers and traders in securities who use a mark-to-market method of tax accounting, persons who hold the shares or ADSs as a hedge against currency risks, as a position in a “straddle” for tax purposes, or as part of a conversion or other integrated transaction, persons holding our shares or ADSs in connection with a trade or business conducted outside of the U.S., partnerships or other entities classified as partnerships or other pass-through entities for U.S. federal income tax purposes or partners in such partnerships or entities, or persons who own (directly, indirectly or by attribution) 10% or more of the combined voting power of all classes of equity in the Company or 10% or more of the combined value of all classes of equity in the Company. PERSONS OR ENTITIES DESCRIBED ABOVE, INCLUDING PARTNERSHIPS HOLDING SHARES OR ADSs OR PARTNERS IN SUCH PARTNERSHIPS, SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR U.S. FEDERAL INCOME TAX CONSEQUENCES OF HOLDING AND DISPOSING OF SHARES OR ADSs.

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of shares or ADSs that is, for U.S. federal income tax purposes, (a) an individual who is a U.S. citizen or resident, (b) a corporation or other entity taxable as a corporation created or organized under the laws of the U.S. or any political subdivision thereof, (c) an estate, the income of which is subject to U.S. federal income tax regardless of the source, or (d) a trust (i) that validly elects to be treated as a U.S. person for U.S. federal income tax purposes or (ii) if (A) a court within the U.S. is able to exercise primary supervision over the administration of the trust and (B) one or more U.S. persons have the authority to control all substantial decisions of the trust.

If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds shares or ADSs, the tax treatment of the partnership and a partner in such partnership generally will depend on the status of the partner and the tax treatment of the partnership. Such a partner or partnership should consult its own tax advisor as to its consequences.

As of this date, there is currently no applicable income tax treaty in effect between the United States and Chile. However, in 2010, the U.S. and Chile signed an income tax treaty that will enter into force once the treaty is ratified by both countries. There can be no assurance that the treaty will be ratified by either country. The following summary assumes that there is no applicable income tax treaty in effect between the U.S. and Chile.

The discussion below does not address the effect of any U.S. state, local, estate or gift tax law or non-U.S. tax law or tax considerations that arise from rules of general application to all taxpayers on a U.S. Holder of the shares or ADSs. U.S. HOLDERS OF SHARES OR ADSs SHOULD CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR CONSEQUENCES UNDER ANY SUCH LAW OF OWNING OR DISPOSING THE SHARES OR ADSs.

129

For purposes of applying U.S. federal income tax law, any U.S. Holder of an ADS generally will be treated as the owner of the underlying shares represented thereby. The U.S. Treasury has expressed concerns that parties to whom ADSs are released before shares are delivered to the depositary (pre-release) or intermediaries in the chain of ownership between beneficial owners and the issuer of the security underlying the ADSs may be taking actions that are inconsistent with the claiming of foreign tax credits for beneficial owners of depositary shares. Such actions would also be inconsistent with the claiming of the reduced tax rate, described below, applicable to dividends received by certain non-corporate beneficial owners. Accordingly, the analysis of the creditability of Chilean taxes, and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described below, could be affected by actions taken by such parties or intermediaries.

Cash Dividends and Other Distributions

The following discussion of cash dividends and other distributions is subject to the discussion below under “Passive Foreign Investment Company Rules.” Distributions received by a U.S. Holder on shares or ADSs, including the amount of any Chilean taxes withheld, other than certain pro rata distributions of shares to all shareholders, will constitute foreign-source income to the extent paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. The amount of dividend income paid in Chilean pesos that a U.S. Holder will be required to include in income will equal the U.S. dollar value of the distributed Chilean peso, calculated by reference to the exchange rate in effect on the date the payment is received, regardless of whether the payment is converted into U.S. dollars on the date of receipt. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder will generally not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of its receipt, which would be ordinary income or loss and would be treated as income from U.S. sources for foreign tax credit purposes. Dividends will be included in a U.S. Holder’s income on the date of the U.S. Holder’s, or in the case of ADSs, the depositary’s, receipt of the dividend. Corporate U.S. Holders will not be entitled to claim the dividends-received deduction with respect to dividends paid by us.

Subject to certain exceptions for short-term and hedged positions, the discussion above regarding concerns expressed by the U.S. Treasury and the discussion below regarding rules intended to be promulgated by the U.S. Treasury, the U.S. dollar amount of dividends received by a noncorporate U.S. Holder in respect of our shares or ADSs generally will be subject to taxation at preferential rates if the dividends are “qualified dividends.” Dividends paid on our ADSs generally will be treated as qualified dividends if (i) our ADSs are readily tradable on an established securities market in the U.S. (ii) SQM was not, in the year prior to the year in which the dividend was paid, and is not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”) and (iii) the holder thereof has satisfied certain holding period requirements. Our ADSs are listed on the New York Stock Exchange and generally will qualify as readily tradable on an established securities market in the U.S. so long as they are so listed. We do not believe that we were a PFIC for U.S. federal income tax purposes with respect to our 2020 taxable year. In addition, based on our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2021 taxable year. However, because PFIC status depends upon the composition of a company’s income and assets and the market value of its assets from time to time, and because it is unclear whether certain types of our income constitute passive income for PFIC purposes, there can be no assurance that we will not be considered a PFIC for any current, prior or future taxable year. Based on existing guidance, it is not entirely clear whether dividends received with respect to our shares will be treated as qualified dividends, because our shares are not themselves listed on a U.S. exchange. In addition, the U.S. Treasury has announced its intention to promulgate rules pursuant to which holders of ADSs and intermediaries through whom such securities are held will be permitted to rely on certifications from issuers to establish that dividends are treated as qualified dividends. Because such procedures have not yet been issued, it is not clear whether we will be able to comply with them. A U.S. HOLDER SHOULD CONSULT ITS TAX ADVISORS TO DETERMINE WHETHER THE FAVORABLE RATE WILL APPLY TO DIVIDENDS IT RECEIVES AND WHETHER IT IS SUBJECT TO ANY SPECIAL RULES THAT LIMIT ITS ABILITY TO BE TAXED AT THIS FAVORABLE RATE.

130

The amount of a dividend generally will be treated as foreign-source dividend income to a U.S. Holder for foreign tax credit purposes. As discussed in more detail below under “—Foreign Tax Credits,” it is not free from doubt whether Chilean withholding taxes imposed on distributions on our shares or ADSs will be treated as income taxes eligible for a foreign tax credit for U.S. federal income tax purposes. If a Chilean withholding tax is treated as an eligible foreign income tax, subject to generally applicable limitations, you may claim a credit against your U.S. federal income tax liability for the eligible Chilean taxes withheld from distributions on our shares or ADSs. If the dividends are taxed as qualified dividend income (as discussed above), special rules will apply in determining the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation. THE RULES RELATING TO FOREIGN TAX CREDITS ARE COMPLEX. YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISORS REGARDING THE TREATMENT OF CHILEAN WITHHOLDING TAXES IMPOSED ON DISTRIBUTIONS ON OUR SHARES OR ADSs.

Sale or Other Disposition of our Shares or ADSs

For U.S. federal income tax purposes, the gain or loss a U.S. Holder realizes on the sale or other disposition of our shares or ADSs generally will be U.S.-source capital gain or loss for foreign tax credit purposes, and generally will be a long-term capital gain or loss if the U.S. Holder has held our shares or ADSs for more than one year. The amount of a U.S. Holder’s gain or loss will equal the difference between the U.S. Holder’s tax basis in our shares or ADSs disposed of and the amount realized on the disposition (including any amount withheld in respect of Chilean withholding taxes), in each case as determined in U.S. dollars.

In certain circumstances, Chilean taxes may be imposed upon the sale of shares. See “—Material Chilean Tax Considerations—Capital Gains” above. As discussed in more detail below under “—Foreign Tax Credits,” subject to generally applicable limitations and substantiation requirements, a U.S. Holder may be eligible to claim a credit against its U.S. federal income tax liability for the eligible Chilean taxes withheld pursuant to a sale or other disposition of our shares or ADSs. U.S. HOLDERS ARE URGED TO CONSULT THEIR OWN U.S. TAX ADVISORS WITH RESPECT TO THE PARTICULAR CONSEQUENCES TO THEM OF OWNING OR DISPOSING OF OUR SHARES OR ADSs.

Foreign Tax Credits

Subject to applicable limitations that may vary depending upon a U.S. Holder’s circumstances and subject to the discussion above regarding concerns expressed by the U.S. Treasury, you may be eligible to claim a credit against your U.S. tax liability for Chilean income taxes (or taxes imposed in lieu of an income tax) imposed in connection with distributions on and proceeds from the sale or other disposition of our shares or ADSs. Chilean dividend withholding taxes generally are expected to be income taxes eligible for the foreign tax credit. The Chilean capital gains tax is likely to be treated as an income tax (or a tax paid in lieu of an income tax) and thus eligible for the foreign tax credit; however, you generally may claim a foreign tax credit only after taking into account any available opportunity to reduce the Chilean capital gains tax, such as the reduction for the credit for Chilean corporate income tax that is taken into account when calculating Chilean withholding tax. If a Chilean tax is imposed on the sale or disposition of our shares or ADSs, and a U.S. Holder does not receive significant foreign source income from other sources, such U.S. Holder may not be able to credit such Chilean tax against its U.S. federal income tax liability. If a Chilean tax is not treated as an income tax (or a tax paid in lieu of an income tax) for U.S. federal income tax purposes, a U.S. Holder would be unable to claim a foreign tax credit for any such Chilean tax withheld; however, a U.S. Holder may be able to deduct such tax in computing its U.S. federal income tax liability, subject to applicable limitations. In addition, instead of claiming a credit, a U.S. Holder may, at the U.S. Holder’s election, deduct such Chilean taxes in computing the U.S. Holder’s taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all taxes paid or accrued in the taxable year to foreign countries and possessions of the U.S. THE CALCULATION OF FOREIGN TAX CREDITS AND, IN THE CASE OF A U.S. HOLDER THAT ELECTS TO DEDUCT FOREIGN INCOME TAXES, THE AVAILABILITY OF DEDUCTIONS, INVOLVES THE APPLICATION OF COMPLEX RULES THAT DEPEND ON YOUR PARTICULAR CIRCUMSTANCES. U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE AVAILABILITY OF FOREIGN TAX CREDITS IN THEIR PARTICULAR CIRCUMSTANCES.

131

Passive Foreign Investment Company Rules

We do not expect to be a PFIC for U.S. federal income tax purposes for our 2020 taxable year and do not anticipate being a PFIC for our 2021 taxable year. However, because PFIC status depends upon the composition of a company’s income and assets and the market value of its assets from time to time, and because it is unclear whether certain types of our income constitute passive income for PFIC purposes, there can be no assurance that we will not be considered a PFIC for any current, prior or future taxable year. If we were a PFIC for any taxable year during which a U.S. Holder held our shares or ADSs, certain adverse consequences could apply to the U.S. Holder, including the imposition of higher amounts of tax than would otherwise apply, and additional filing requirements. In addition, if we were treated as a PFIC in a taxable year in which we pay a dividend or in the prior taxable year, the favorable dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply (see “—Cash Dividends and Other Distributions” above). A U.S. Holder should consult its tax advisors regarding the consequences to it if we were a PFIC, as well as the availability and advisability of making any election that might mitigate the adverse consequences of PFIC status.

Information Reporting and Backup Withholding

Required Disclosure with Respect to Foreign Financial Assets

Certain U.S. Holders are required to report information relating to an interest in our shares or ADSs, subject to certain exceptions (including an exception for our shares or ADSs held in accounts maintained by certain financial institutions), by attaching a completed IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold an interest in our shares or ADSs. U.S. HOLDERS ARE URGED TO CONSULT THEIR OWN U.S. TAX ADVISORS REGARDING INFORMATION REPORTING REQUIREMENTS RELATING TO THEIR OWNERSHIP OF OUR SHARES OR ADSs.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the U.S. or through certain U.S.-related financial intermediaries generally are subject to information reporting and to backup withholding unless (i) the U.S. Holder is an exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against its U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the U.S. Internal Revenue Service.

Medicare Contribution Tax

Legislation enacted in 2010 generally imposes a tax of 3.8% on the “net investment income” of certain individuals, trusts and estates. Among other items, net investment income generally includes gross income from dividends and net gain attributable to the disposition of certain property, like our shares or ADSs, less certain deductions. A U.S. Holder should consult the U.S. Holder’s tax advisor regarding the possible application of this legislation in the U.S. Holder’s particular circumstances.

A U.S. HOLDER SHOULD CONSULT ITS OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR CONSEQUENCES TO IT OF OWNING AND DISPOSING OF OUR SHARES OR ADSs.

ITEM 15. CONTROLS AND PROCEDURES

(a) Disclosure Control and Procedures

SQM management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer and other members of the Company’s executive management, evaluated the effectiveness of our disclosure controls and procedures, pursuant to Rule 13a-15(b) promulgated under the Exchange Act, as of the end of the period covered by this Annual Report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective in providing reasonable assurance that material information is made known to management and that financial and non-financial information is properly recorded, processed, summarized and reported as of December 31, 2021.

The Company’s disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and that such information is accumulated and communicated to management of the Company, with the participation of its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures. However, through the same design and evaluation period of the disclosure controls and procedures, the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, recognized that there are inherent limitations to the effectiveness of any control system regardless of how well designed and operated. In such a way they can provide only reasonable assurance of achieving the desired control objectives, and no evaluation can provide absolute assurance that all control issues or instances of fraud, if any, within the Company have been detected.

(b)

Management’s Annual Report on Internal Control Over Financial Reporting

SQM management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f). The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not necessarily prevent or detect some misstatements. It can only provide reasonable assurance regarding financial statement preparation and presentation. Also, projections of any evaluation of effectiveness for future periods are subject to the risk that controls may become inadequate because of changes in conditions or because the degree of compliance with the polices or procedures may deteriorate over time.

Management assessed the effectiveness of its internal control over financial reporting as of December 31, 2021. The assessment was based on criteria established in the framework “Internal Controls — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the assessment, SQM management has concluded that as of December 31, 2021, the Company’s internal control over financial reporting was effective.

For the report of PricewaterhouseCoopers Consultores Auditores SpA, independent registered public accounting firm on the effectiveness of our internal control over financial reporting as of December 31, 2021, see page F-1 of our Audited Consolidated Financial Statements.

(d) Changes in Internal Control Over Financial Reporting

There has been no change in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period covered by this Annual Report that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

ITEM 16.  [Reserved]

ITEM  16A. AUDIT COMMITTEE FINANCIAL EXPERT

The Board of Directors has determined that the Company does not have an audit committee financial expert within the meaning of the regulations adopted under the Sarbanes-Oxley Act of 2002.

Pursuant to Chilean regulations, the Company has a Directors’ Committee whose main duties are similar to those of an audit committee. Each of the members of the Directors’ Committee is a member of the audit committee. See “Item 6.C. Board Practices.”

Our Board believes that the members of the Directors’ Committee have the necessary expertise and experience to perform the functions of the Directors’ Committee pursuant to Chilean regulations.

ITEM 16B. CODE OF ETHICS

We have adopted a Code of Business Conduct that applies to the Chief Executive Officer, the Chief Financial Officer, the Internal Auditor as well as all our officers and employees. Our Code adheres to the definition set forth in Item 16B. of Form 20-F under the Exchange Act.

No waivers have been granted therefrom to the officers mentioned above.

The full text of the Code is available on our website at

http://www.sqm.com

Amendments to, or waivers from, one or more provisions of the Code will be disclosed on our website.

Audit fees in the above table are the fees approved by the Directors’ Committee for PwC in 2021 and 2020 in connection with the audits of our annual consolidated financial statements

Tax fees and all other fees in the above table are aggregate fees approved by the Directors’ Committee for PwC in 2021 and 2020 in connection with services such as transfer pricing and other assurance services that were not related to the audit. These fees were pre-approved by the Directors’ Committee in accordance with our pre-approval policies and procedures.

Directors’ Committee Pre-Approval Policies and Procedures.

Chilean law states that public companies are subject to “pre-approval” requirements under which all audit and non-audit services provided by the independent auditor must be pre-approved by the Directors’ Committee. Our Directors’ Committee approves all audits, audit related, tax and other services provided by our auditors.

Any services provided by our auditors that are not specifically included within the scope of the audit must be pre-approved by the Directors’ Committee prior to any engagement.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Sociedad Química y Minera de Chile S.A. and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of income, comprehensive income, changes in equity and, cash flows for each of the three years in the period ended December 31, 2021, 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 each of the three years in the period ended December, 31, 2021 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 Management’s Annual 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.

F-7

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.

Bulk Inventories Volume

As described in Notes 3.14, 3.33 and 10 to the consolidated financial statements, the Company’s consolidated products in progress and finished products inventories balances at December 31, 2021 amounted to US$527 million and US$603 million, respectively, which included bulk inventories amounting to US$ 111 million and US$100 million, respectively. The accounting process the Company uses to record products in progress and finished products bulk inventories volume relies on significant estimates primarily relating to topography measures and product density. To assist in validating the reasonableness of these estimates, management periodically reviews product density and performs cyclical physical inventory during the year and an annual physical inventory.

The principal considerations for our determination that performing procedures relating to the bulk inventories volume is a critical matter are (i) the significant judgment by management in determining the products in progress and finished products bulk inventories volume; (ii)  a high degree of  auditor judgment, subjectivity, and effort in performing our audit procedures and in evaluating audit evidence related to the estimates made by management; and (iii) 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 testing the effectiveness of controls relating to the estimation of inventories volumes, including controls over management’s physical inventory process and the determination of the product density. These procedures also included, among others, observing management’s physical inventory and assessing rollforward activity between the time of the inventory and year-end. Professionals with specialized skill and knowledge were used to assist in the evaluation of management’s topography measures, assess the reasonableness of management’s determination of the product density and observe management’s annual physical inventory.

Litigation - Environmental, Tax and Legal Contingencies

As described in Notes 3.26, 3.33, and 20 to the consolidated financial statements, provisions are recognized when the Company has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate of the obligation amount can be made.No provision for an estimated loss is recorded in the consolidated financial statements for unfavorable outcomes when, after assessing the information available, (i) management concludes that it is not probable that a loss has been incurred in any of the pending litigation; or (ii) management is unable to reliably estimate the loss for any of the pending matters.  The Company also discloses the contingency in circumstances where management concludes no loss is probable or reliably estimable, but it is reasonably possible that a loss may be incurred.

The principal considerations for our determination that performing procedures relating to the environmental, tax and legal contingencies is a critical audit matter are the significant judgment by management when assessing the likelihood of a loss being incurred and when determining whether a reliable estimate of the loss can be made, which in turn led to a high degree of auditor judgment and effort in evaluating management’s assessment of the loss contingencies associated with environmental, tax and legal matters.

F-8

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 testing the effectiveness of controls relating to management’s evaluation of the environmental, tax and legal contingencies, including controls over determining whether a loss is probable and whether the amount of loss can be reliably estimated, as well as consolidated financial statement disclosures. These procedures also included, among others, obtaining and evaluating the letters of audit inquiry with internal and external legal counsels, evaluating the reasonableness of management’s assessment regarding unfavorable outcomes, and evaluating the sufficiency of the Company’s litigation contingency disclosures.

1.6 Covid-19

In January 2020, the WHO deemed COVID-19 a global pandemic. In March 2020, the Chilean Ministry of Health declared a nationwide State of Emergency. As a precaution, our management has implemented several measures to help reduce the speed at which the coronavirus spreads, including measures to mitigate the spread in the workplace, significant reductions in employee travel and a mandatory quarantine for people who have arrived from high risk destinations, in consultation with governmental and international health organization guidelines, and will continue to implement measures consistent with evolving coronavirus situation.

The Company reports on the following points in relation to the outbreak of the COVID-19 virus and its being declared to be a global pandemic by the WHO:

(1) Regarding the financial and operational effects that this situation could mean for the Company, it is worth noting that the Company sells its products worldwide, with Asia, Europe and North America being its main markets. Border closures, decrease in commercial activity and difficulties and disruptions in the supply chains in the markets in which we sell have impacted our ability to fulfill our previous sales volume estimates, the impact on our sales volumes and average prices will depend on the duration of the virus in different markets, the efficiency of the measures implemented to contain the spread of the virus in each country and fiscal incentives that may be implemented in different jurisdictions to promote economic recovery.

For now, our operations have not seen any material impacts related to the outbreak of COVID-19 virus.

We have taken measures to mitigate the impacts of this health emergency on our employees and limit the impact it could have on our operations (described below in point 2).

Notes to the Consolidated Financial Statements  
December 31, 2021

(2) Regarding the measures that management has adopted or intends to adopt to mitigate possible financial and/or operational effects, we inform that the Company has implemented a series of measures in its operations in Chile and abroad that seek to protect its workers and reduce the speed at which the virus spreads. The measures adopted by the Company are:

(a) The flexibility of the working day, arrival and departure times, together with the incentive to work from home in those cases where this is possible.

(b) Avoidance of crowds, seminars and large meetings in the Company´s offices and operating facilities.

(c) Strengthening personal hygiene protocols (use of alcohol-based gel, masks, etc.) and sanitation in plants, cafeterias and offices.

(d) Significant reduction in domestic and international travel, along with obligatory quarantine for people who have arrived from high risk destinations.

(e) The costs associated with the measures implemented by the company correspond primarily to increased expenses in transportation, supplies, room and board, among others.

(3) We hereby inform that we do not currently have any other information that management believes is relevant to provide.

This amendment extends by one year the period of application of the practical case of IFRS 16 Leases (contained in the amendment to that standard published in May 2020), with the purpose of assisting lessees in accounting for COVID-19 related rental concessions.

Notes to the Consolidated Financial Statements  
December 31, 2021

(b) Standards, interpretations and amendments issued that had not become effective for financial statements beginning on January 1, 2021 and which the Company has not adopted early are as follows:

Standards and Interpretations	Description	Mandatory for annual periods beginning on or after
Amendment to IAS 1 “Presentation of financial statements” on classification of liabilities.	These amendments clarify that the liabilities will be classified as current or non-current depending on the rights that exist at the close of the reporting period. The classification is not affected by the expectations of the entity or the events subsequent to the report date (for example, the receipt of a waiver or noncompliance with the pact). The amendment also clarifies what IAS 1 means when referring to “liquidation” of a liability.  The amendment must be applied retroactively in accordance with IAS 8.	01-01-202 3
Reference to the Conceptual Framework - Amendments to IFRS 3.	Minor modifications were made to IFRS 3 “Definition of a Business” to update references to the conceptual framework for financial reporting without changing the requirements of business combinations.	01-01-2022
Amendment to IAS 16 “Property, plant and equipment”.	This prohibits companies from deducting from the cost of the property any revenue received from the sale of articles produced while the company is preparing the asset for its anticipated use. The company must recognize this sales revenue and associated costs in the profit or loss for the fiscal year.	01-01-2022
Amendment to IAS 37, “Provisions, contingent liabilities and contingent assets”.	This clarifies for onerous contracts which inevitable costs a company must include to assess whether a contract will result in a loss.	01-01-2022
Annual improvements to IFRS standards, 2018-2020 cycle. The following improvements were finalized in May 2020:
IFRS 9 Financial Instruments.	This clarifies which fees must be included in the 10% test for the derecognition of financial liabilities.	01-01-2022
IFRS 16 Leases.	Modification of illustrative example 13 to eliminate the illustration of lessor payments in relation to improvements to rental properties, to eliminate any confusion as to the treatment of lease incentives.	01-01-2022
Amendments to IAS 1: “Presentation of the Financial Statements” and IAS 8 “Accounting policies, changes in accounting estimates and errors”.	The amendments are intended to improve disclosures of accounting policies and to help users of financial statements distinguish between changes in accounting estimates and changes in accounting policies.	01-01-2023
Amendment to IAS 12 - Deferred taxes related to assets and liabilities that arise from a single transaction.	These amendments require companies to recognize deferred taxes on transactions that result in equal amounts in taxable and deductible temporary differences in the initial recognition.	01-01-2023
Amendment to IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures”, Published in September 2014.	These amendments address an inconsistency between the requirements in IFRS 10 and those in IAS 28 in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary.	undetermined

Management believes that the adoption of the above standards, amendments and interpretations will not have a significant impact on the Company’s financial statements.

2.5 Basis of consolidation

(a) Subsidiaries

The Company established control as the basis of consolidation of its financial statements. The Company controls a subsidiary when it is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary.

The consolidation of a subsidiary starts when the Group controls it and it is no longer included in the consolidation when this control is lost.

Subsidiaries are consolidated through a line by line method, adding items that represent assets, liabilities, income and expenses with a similar content, and eliminating operations between companies within the SQM Group.

Results for dependent companies acquired or disposed of during the period are included in the consolidated accounts from the date on which control is transferred to the SQM Group or until the date when this control ends, as relevant.

To account for an acquisition of a business, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, equity securities issued, and incurred or assumed liabilities at the date of exchange. Assets, liabilities and contingencies identifiable assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure the non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquire.

The following tables

lists the principal subsidiaries controlled by the Group

Notes to the Consolidated Financial Statements  
December 31, 2021

2.6 Investments in associates and joint ventures

Investments in joint arrangements are classified as 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.

(a) Joint operations

The Company recognizes its direct right to the assets, liabilities, income and expenses of the joint arrangement.

(b) Joint ventures and investments in associates

Interests in companies over which joint control is exercised (joint ventures) or where an entity has significant influence (associates) are recognized using the equity accounting method. Significant influence is presumed when the investor owns over 20% of the investee’s share capital. The investment is recognized using this method in the statement of financial position at cost plus changes subsequent to acquisition and includes the proportional share of the associate’s equity. For these purposes, the percentage interest in the associate is used. The associated acquired goodwill is included in the investee’s book value and is not amortized. The debit or credit to the income statement reflects the proportional share of the profit or loss of the associate.

Unrealized gains from transactions with joint ventures or associates are eliminated in accordance with the Company's percentage interest in such entities. Any unrealized losses are also eliminated, unless that transaction provides evidence that the transferred asset is impaired.

Changes in associate’s or joint ventures equity are recognized proportionally with a charge or credit to "Other Reserves" and are classified according to their origin. The reporting dates of the associate or joint ventures, the Company and related policies are similar for equivalent transactions and events in similar circumstances. In the event that significant influence is lost, or the investment is sold, or held for sale, the equity method is suspended, not recognizing the proportional share of the gain or loss. If the resulting value under the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless there is a commitment by the Company to restore the capital position of the Company, in which case the related risk provision and expense are recorded.

Dividends received by these companies are recorded by reducing the value of the investment and are shown in cash flows from operating activities, and the proportional share of the gain or loss recognized in accordance with the equity method is included in the consolidated income statement under "Share of Gains (Losses) of Associates and Joint Ventures Accounted for Using the Equity Method''.

Note 3 Significant accounting policies

3.1 Classification of balances as current and non-current

In the consolidated statement of financial position, balances are classified in consideration of their recovery (maturity) dates; i.e., those maturing within a period equal to or less than 12 months are classified as current counted from the closing date of the consolidated financial statements and those with maturity dates exceeding the aforementioned period are classified as non-current.

The exception to the foregoing relates to deferred taxes, which are classified as non-current, regardless of the maturity they have.

3.2 Functional and presentation currency

The Company’s consolidated financial statements are presented in United States dollars, without decimal places, which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates. Consequently, the term foreign currency is defined as any currency other than the U.S. dollar.

3.3 Accounting policy for foreign currency translation

(a) SQM group entities:

The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows:

- Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date.

- Revenues and expenses of each profit or loss account are converted at monthly average exchange rates.

- All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves.

In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in shareholder’s equity (“foreign currency translation reserve”). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale.

(*) US$ per UF

(b) Transactions and balances

The Company’s non-monetary transactions in currencies other than the functional currency (Dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income until disposal of the investment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income.

Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items that are measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined.

3.4 Consolidated statement of cash flows

Cash equivalents correspond to highly liquid short-term investments that are easily convertible into known amounts of cash and subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument.

For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above.

The statement of cash flows present cash transactions performed during the period, determined using the direct method.

3.5 Financial assets accounting policy

Management determines the classification of its financial assets at fair value (either through other comprehensive income, or through profit or loss), and at amortized cost. The classification depends on the business model of the entity to manage the financial assets and the contractual terms of the cash flows.

In the initial recognition, the Company measures its financial assets at fair value more or less, in the case of a financial asset that is not accounted for at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial asset on the date when the Company commits to the purchase or sale of an asset. In the case of account receivables and other accounts receivables, the transaction price at the initial recognition is measured.

After initial recognition, the Company measures its financial assets according to the Company's business model for managing its financial assets and the contractual terms of its cash flows:

(a) Financial instruments measured at amortized cost. Financial assets that meet the following conditions are included in this category (i) the business model that supports it aims to maintain the financial assets to obtain the contractual cash flows and the contractual conditions of the financial asset give place, on specified dates, to cash flows that are only payments of the principal and interest on the outstanding principal amount. The Company’s financial assets that meet these conditions are: (ii) cash equivalents; (iii) related party receivables; (iv) trade debtors; (v) other receivables.

(b) Financial instruments at fair value. A financial asset should be measured at fair value through profit or loss or fair value through other comprehensive income, depending on the following:

(i) "Fair Value Through Other Comprehensive Income": Assets held to collect contractual cash flows and to be sold, where the asset cash flows are only capital and interest payments, are measured at fair value through other comprehensive income. Changes in book values are through other comprehensive income, except for the recognition of impairment losses, interest income and exchange gains and losses, which are recognized in the income statement. When a financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to the income statement. Interest income from these financial assets is included in financial income using the effective interest method.

(ii) "Fair Value Through Profit and Loss": Assets that do not meet the amortized cost or "Fair Value Through Other Comprehensive Income" criteria are valued at "Fair Value Through Profit and Loss".

(c) Financial equity assets at fair value through other comprehensive income. Equity instruments that are not classified as held for trading and which the Group has irrevocably chosen to recognize in this category. Amounts presented in other comprehensive income will not be subsequently transferred to profit or loss.

The Company evaluates expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment method used depends on whether there has been a significant increase in credit risk.

The Company applies simplified approach to measure expected credit losses using the lifetime expected loss on all trade receivables. Expected credit losses are measured by grouping receivables by their shared credit risk characteristics and days overdue.

The Company has concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for contract assets. Expected loss rates are based on sales payment profiles and historical credit losses within this period. Historical loss rates are adjusted to reflect current expectations and information regarding macroeconomic factors that affect the ability of customers to meet their commitments.

Impairment losses from receivables and contract assets are shown as net impairment losses in the line “Impairment of financial assets and reversal of impairment losses,” see Note 21.7. The subsequent recovery of previously canceled amounts are credited to the same line.

3.7 Financial liabilities

Management determines the classification of its financial liabilities at fair value or at amortized cost. The classification depends on the business model of the entity to manage the financial liabilities and the contractual terms of the cash flows.

At the initial recognition, the Company measures its financial liabilities by their fair value more or less, in the case of a financial liability that is not accounted for at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial liability. After initial recognition, the Company measures its financial liabilities at amortized cost unless the Company, at the initial moment, irrevocably designates the financial liability as measured at fair value through profit or loss.

Financial liabilities measured at amortized cost are commercial accounts payable and other accounts payable and other financial liabilities.

Amortized cost is based using the effective interest rate method. Amortized cost is calculated by considering any premium or discount on the acquisition and includes transaction costs that are an integral part of the effective interest rate.

Financial liabilities are recorded as not current when they mature in more than 12 months and as current when they mature in less than 12 months.

3.8 Reclassification of financial instruments

When the Company changes its business model for managing financial assets, it will reclassify all its financial assets affected by the new business model. Financial liabilities cannot be reclassified.

3.9 Financial instruments derecognition

The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained.

The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished from the principle responsibility contained in the liability.

3.10 Derivative and hedging financial instruments

Derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows:

a) Fair value hedge of assets and liabilities recognized (fair value hedges);

b) Hedging of a single risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge).

At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations.

The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items.

The fair value of derivative instruments used for hedging purposes is shown in Note 12.3. Changes in the cash flow hedge reserve are classified as a non-current asset or liability if the remaining expiration period of the hedged item is more than 12 months, and as a current asset or liability if the remaining expiration period of the hedged item is less than 12 months.

Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss.

a) Fair value hedge

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate.

b) Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is initially recognized with a debit or credit to other comprehensive income, while any ineffective portion is immediately recognized with a debit or credit to income, as appropriate depending on the nature of the hedged risk. The amounts accumulated in net equity are carried over to results when the hedged items are settled or when these have an impact on results.

When a hedging instrument no longer meets the criteria for hedge accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs.

When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss.

3.11 Derivative financial instruments not considered as hedges

Derivative financial instruments not considered as hedges are recognized at fair value with the effect in the results of the year. The Company has derivative financial instruments to hedge foreign currency risk exposure.

The Company continually evaluates the existence of embedded derivatives in both its contracts and in its financial instruments. As of December 31, 2021, and 2020, the Company does not have any embedded derivatives.

3.12 Deferred acquisition costs from insurance contracts

Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis independent of payment date. These are recognized under other non-financial assets.

3.13 Leases

(a) Right-of-use assets

The Company recognizes right-of-use assets on the initial lease date (i.e., the date on which the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, adjusted by any new measurement of the lease liability. The cost of right-of-use assets includes the amount of recognized lease liabilities, direct initial costs incurred and lease payments made on the start date or sooner, less the lease incentives received. Unless the Company is reasonably sure it will take ownership of the leased asset at the end of the lease period, the assets recognized through right-of-use are depreciated in a straight line during the shortest period of their estimated useful life and lease period. Right-of-use assets are subject to impairment.

(b) Lease liabilities

On the lease start date, the Company recognizes lease liabilities measured at present value of lease payments that will be made during the lease period. Lease payments include fixed payments (including payments that are essentially fixed), less incentives for lease receivables, variable lease payments that are dependent on an index or rate and amounts that are expected to be paid as guaranteed residual value. Lease payments also include the exercise price of a purchase option if the Company is reasonably sure it will exercise this and penalty payments for terminating a lease, if the lease period reflects that the Company will exercise the option to terminate. Variable lease payments that are not dependent on an index or rate are recognized as expenses in the period that produces the event or condition that triggers payment.

When calculating the present value of lease payments, the Company uses the incremental borrowing rate on the initial lease date if the interest rate implicit in the lease cannot be determined easily. After the start date, the lease liability balance will increase to reflect the accumulation of interest and will diminish as lease payments are made. Furthermore, the book value of lease liabilities is remeasured in the event of an amendment, a change in the lease period, a change in the fixed lease payments in substance or a change in the assessment to buy the underlying asset.

Payments made that affect lease liabilities are presented as part of the financing activities in the cash flow statement.

(c) Short-term leases and low-value asset leases

The Company applies the short-term lease recognition exemption to leases with a lease term of 12 months or less starting on the start date and that don’t have a purchase option. It also applies the low-value asset lease recognition exemptions to leases less than the limit specified in the respective accounting standard. Lease payments in short-term leases and low-value asset leases are recognized as lineal expenses during the lease term.

(d) Significant judgments in the determination of the lease term for contracts with renewal options.

The Company determines the lease term as the non-cancellable period of the lease, together with periods covered by an option to extend the lease if it is reasonably certain that this will be exercised, or any period covered by an option to terminate the lease, if it is reasonably certain that this will not be exercised.

The Company has the option, under some of its leases, to lease assets for additional terms. The Company applies its judgment when assessing whether it is reasonably certain that it will exercise the option to renovate. In other words, it considers all the relevant factors that create an economic incentive for it to exercise the option to renovate. After the start date, the Company reevaluates the lease term if there is a significant event or change in the circumstances that are under its control and affect its capacity to exercise (or not exercise) the option to renovate.

3.14 Inventory measurement

The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage. In determining production costs for own products, the company includes the costs of labor, raw materials, materials and supplies used in production, depreciation and maintenance of the goods that participate in the production process, the costs of product movement necessary to maintain stock on location and in the condition in which they are found, and also includes the indirect costs of each task such as laboratories, process and planning areas, and personnel expenses related to production, among others.

For finished and in-process products, the company has four types of provisions, which are reviewed quarterly:

(a) Provision associated with the lower value of stock: The provision is directly identified with the product that generates it and involves three types: (i) provision of lower realizable value, which corresponds to the difference between the inventory cost of intermediary or finished products, and the sale price minus the necessary costs to bring them to the same conditions and location as the product with which they are compared; (ii) provision for future uncertain use that corresponds to the value of those products in process that are likely not going to be used in sales based on the company’s long-term plans; (iii) reprocessing costs of products that are unfeasible for sale due to current specifications.

(b) Provision associated with physical differences in inventory: A provision is made for differences that exceed the tolerance considered in the respective inventory process (physical and annual inventories are taken for the productive units in Chile and the port of Tocopilla; the business subsidiaries depend on the last zero ground obtained, but in general it is at least once a year), these differences are recognized immediately.

(c) Potential errors in the determination of stock: The company has an algorithm that is reviewed at least once a year and corresponds to diverse percentages assigned to each inventory based on the product, location, complexity involved in the associated measurement, rotation and control mechanisms.

(d) Provisions undertaken by business subsidiaries: these are historical percentages that are adjusted as zero ground is attained based on normal inventory management.

F-35

Notes to the Consolidated Financial Statements  
December 31, 2021

Inventories of raw materials, materials and supplies for production are recorded at acquisition cost. Cyclical inventories are performed in warehouses, as well as general inventories every three years. Differences are recognized at the moment they are detected. The company has a provision that makes quarterly calculations from percentages associated with each type of material (classification by warehouse and rotation), these percentages use the lower value resulting from deterioration or obsolescence as well as potential losses. This provision is reviewed at least annually, and considers the historical profit and loss obtained in the inventory processes.

3.15 Non-controlling interests

Non-controlling interests are recorded in the consolidated statement of financial position within equity but separate from equity attributable to the owners of the Parent.

3.16 Related party transactions

Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. The maturity conditions vary according to the originating transaction.

3.17 Property, plant and equipment

Property, plant and equipment are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced.

In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable:

(a) Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company.

(b) The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the and its subsequent variation is recorded directly in results.

Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets.

Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date.

Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred.

The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements.

Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (or loss) in the period and calculated as the difference between the asset’s sales value and its net carrying value.

Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred.

F-36

Notes to the Consolidated Financial Statements  
December 31, 2021

3.18 Depreciation of property, plant and equipment

Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets

and depreciated over their expected useful lives.

Useful lives are reviewed on an annual basis.

Fixed assets located in the Salar de Atacama consider useful life to be the lesser value between the technical useful life and the years remaining until 2030.

In the case of certain mobile equipment, depreciation is performed depending on the hours of operation.

The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below:

Classes of property, plant and equipment	Minimum life or rate (years)		Maximum life or rate (years)		Life or average rate in years
Mining assets		3		10		7
Energy generating assets		3		16		9
Buildings		3		25		14
Supplies and accessories		2		10		7
Office equipment		5		10		9
Transport equipment		5		9		7
Network and communication equipment		4		10		5
IT equipment		4		11		7
Machinery, plant and equipment		2		25		13
Other fixed assets		3		20		10

3.19 Goodwill

Goodwill acquired represents the excess in acquisition cost on the fair value of the Company's ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in the line item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold.

This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose.

3.20 Intangible assets other than goodwill

Intangible assets other than goodwill mainly relate to water rights, emission rights, commercial brands, costs for rights of way for electricity lines, license costs and the development of computer software and mining property and concession rights, client portfolio and commercial agent.

F-37

Notes to the Consolidated Financial Statements  
December 31, 2021

(a) Water rights

Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into:

i) Finite rights with amortization using the straight-line method, and

ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company, which are subject to an annual impairment assessment.

(b) Rights of way for electric lines

As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. These rights are presented under intangible asset. Amounts paid are capitalized at the date of the agreement and amortized in the statement of income, according to the life of the right of way.

(c) Computer software

Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives.

Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received.

The costs of development for IT programs are recognized as assets are amortized over their estimated useful lives.

(d) Mining property and concession rights

The Company holds mining property and concession rights from the Chilean and Western Australian Governments. Property rights from the State of Chile are usually obtained at no initial cost (other than the payment of mining patents and minor recording expenses) and once the rights on these concessions have been obtained, they are retained by the Company while annual patents are paid. Such patents, which are paid annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties that are not from the Chilean Government are recorded at acquisition cost within intangible assets.

(e) Estimated useful lives or amortization rates used for finite identifiable intangible assets

The finite useful life of mining properties is calculated using the productive unit method, except for the mining properties owned by Corfo, which have been leased to the Company and grant it the right to exclusively exploit them until December 31, 2030.

The estimated useful life for software which they are amortized corresponds to the periods defined by the contracts or rights from which they originate.

F-38

Notes to the Consolidated Financial Statements  
December 31, 2021

f) Minimum and maximum amortization lives or rates of intangible assets:

Estimated useful life or amortization rate	Minimum Life or Rate	Maximum Life or Rate
Water rights	5 years	Indefinite
Rights of way	Indefinite	Indefinite
Corfo Mining properties (1)	9 years	9 years
Mining rights	Unit-production method
Intellectual property	9 years	9 years
IT programs	2 years	8 years

(1) Mining properties owned by CORFO and leased to the Company, which grant it the exclusive right to exploit them until December 31, 2030.

3.21 Research and development expenses

Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred.

3.22 Exploration and evaluation expenses

The Company holds mining concessions for exploration and exploitation of ore, the Company gives the following treatment to expenses associated with exploration and assessment of these resources:

Once the rights have been obtained, the Company records the disbursements directly associated with the exploration and evaluation of the deposit in execution as property, plant and equipment (construction in progress) at its cost. These disbursements include the following items: geological surveys, drilling, borehole extraction and sampling, activities related to the technical assessment and commercial viability of the extraction, and in general, any disbursement directly related to specific projects where the objective is to find ore resources. If the technical studies determine that the ore grade is not economically viable, the asset is directly charged to profit and loss. If determined otherwise, the asset described above is associated with the extractable ore tonnage which is amortized as it is used.

(a) Limestone and metallic exploration

These assets are included in Other Non-Current Non-Financial Assets, and the portion related to the area to be exploited in the year are reclassified to Current Inventory, if applicable.

Costs related to metal exploration are charged to profit or loss in the period in which they are recognized if the project assessed doesn't qualify for consideration as advanced exploration otherwise, these are amortized during the development stage.

(b) Exploration in Salar de Atacama

Exploration expenses in Salar de Atacama are included in non-current assets under Property, Plant and Equipment and are mainly bore holes that can also be used to exploit the deposit or monitoring, which are amortized over 9 years.

(c) Exploration and evaluation at the Mt. Holland Project

Mount Holland exploration and evaluation expenditure is included in Property, plant and equipment, specifically in Construction in Progress. See Note 1. 8.

F-39

December 31, 2021

3.23 Impairment of non-financial assets

Assets subject to depreciation and amortization are also subject to impairment testing, provided that an event or change in the circumstances indicates that the amounts in the accounting records may not be recoverable, an impairment loss is recognized for the excess of the book value of the asset over its recoverable amount.

For assets other than goodwill, the Group annually assesses whether there is any indication that a previously recognized impairment loss may no longer exist or may have decreased. Should such indications exist, the recoverable amount is estimated.

The recoverable amount of an asset is the higher between the fair value of an asset or cash generating unit less costs of sales and its value in use, and is determined for an individual asset unless the asset does not generate any cash inflows that are clearly independent from other assets or groups of assets.

In evaluating value in use, estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessment, the value of money over time and the specific asset risks.

Impairment losses from continuing operations are recognized with a debit to profit or loss in the categories of expenses associated with the impaired asset function.

For assets other than goodwill, a previously recognized impairment loss is only reversed if there have been changes in the estimates used to determine the asset’s recoverable amount since the last time an impairment loss was recognized. If this is the case, the carrying value of the asset is increased to its recoverable amount. This increased amount cannot exceed the carrying value that would have been determined, net of depreciation, if an asset impairment loss had not been recognized in prior years. This reversal is recognized with a credit to profit or loss.

Assets with indefinite lives are assessed for impairment annually.

The current value of future cash flows generated by these assets has been estimated given the variation in sales volumes, market prices and costs, discounted with a WACC rate. For December 31, 2021, the WACC rate was 9.90%.

3.24 Minimum dividend

As required by Chilean law and regulations, our dividend policy is decided upon from time to time by our Board of Directors and is announced at the Annual Ordinary Shareholders’ Meeting, which is generally held in April of each year. Shareholder approval of the dividend policy is not required. However, each year the Board must submit the declaration of the final dividend or dividends in respect of the preceding year, consistent with the then-established dividend policy, to the Annual Ordinary Shareholders’ Meeting for approval. As required by the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated net income for that year (determined in accordance with CMF regulations), unless and to the extent the Company has a deficit in retained earnings. (See Note 19.5).

3.25 Earnings per share

The basic earnings per share amounts are calculated by dividing the profit for the year attributable to the ordinary owners of the parent by the weighted average number of ordinary shares outstanding during the year.

The Company has not conducted any type of operation of potential dilutive effect that would entail the disclosure of diluted earnings per share.

F-40

Notes to the Consolidated Financial Statements  
December 31, 2021

3.26 Other provisions

Provisions are recognized when:

· The Company has a present, legal or constructive obligation as the result of a past event.

· It is more likely than not that certain resources must be used, to settle the obligation.

· A reliable estimate can be made of the amount of the obligation.

In the event that the provision or a portion of it is reimbursed, the reimbursement is recognized as a separate asset solely if there is certainty of income.

In the consolidated statement of income, the expense for any provision is presented net of any reimbursement.

Should the effect of the value of money over time be significant, provisions are discounted using a discount rate before tax that reflects the liability’s specific risks. When a discount rate is used, the increase in the provision over time is recognized as a finance cost.

The Company’s policy is to maintain provisions to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from current litigation, compensations or obligations, pending expenses for which the amount has not yet been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time the responsibility or the obligation that determines the compensation or payment is generated.

3.27 Obligations related to employee termination benefits and pension commitments

Obligations towards the Company’s employees comply with the provisions of the collective bargaining agreements in force, which are formalized through collective employment agreements and individual employment contracts, except for the United States, which is regulated in accordance with employment plans in force up to 2002. (See more details in Note 17.4).

These obligations are valued using actuarial calculations, according to the projected unit credit method which considers such assumptions as the mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees’ salaries, as well as the effects on variations in services derived from variations in the inflation rate.

Actuarial gains and losses that may be generated by variations in defined, pre-established obligations are directly recorded in “Other Comprehensive Income”.

Actuarial losses and gains have their origin in deviations between the estimate and the actual behavior of actuarial assumptions or in the reformulation of established actuarial assumptions.

The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value. The net balance of this obligation is presented under the “Non-Current Provisions for Employee Benefits” (refer to Note 17.4).

3.28 Compensation plans

Compensation plans implemented through benefits provided in share-based payments settled in cash are recognized in the financial statements at their fair value, in accordance with IFRS 2. Changes in the fair value of options granted are recognized with a charge to payroll in the results for the period (see Note 17.6).

3.29 Revenue recognition

Revenue includes the fair value of considerations received or receivable for the sale of goods and services during the performance of the Company's activities. Revenue is presented net of value added tax, estimated returns, rebates and discounts and after the elimination of sales among subsidiaries.

F-41

Notes to the Consolidated Financial Statements  
December 31, 2021

Revenues are recognized when the specific conditions for each income stream are met, as follows:

(a) Sale of goods

The sale of goods is recognized when the Company has delivered products to the customer, and there is no obligation pending compliance that could affect the acceptance of products by the customer. The delivery does not occur until products have been shipped to the customer or confirmed as received by the customer, and the related risks of obsolescence and loss have been transferred to the customer and the customer has accepted the products in accordance with the conditions established in the sale, when the acceptance period has ended, or when there is objective evidence that those criteria required for acceptance have been met.

Sales are recognized in consideration of the price set in the sales agreement, net of volume discounts and estimated returns at the date of the sale. Volume discounts are evaluated in consideration of annual foreseen purchases and in accordance with the criteria defined in agreements.

(b) Sale of services

Revenue associated with the rendering of services is recognized considering the degree of completion of the service as of the date of presentation of the consolidated classified statement of financial position, provided that the result from the transaction can be estimated reliably.

(c) Income from dividends

Income from dividends is recognized when the right to receive the payment is established.

3.30 Finance income and finance costs

Finance income is mainly composed of interest income from financial instruments such as term deposits and mutual fund deposits. Interest income is recognized in profit or loss at amortized cost, using the effective interest rate method.

Finance costs are mainly composed of interest on bank borrowing expenses, interest on bonds issued and interest capitalized for borrowing costs for the acquisition, construction or production or qualifying assets. Borrowing costs and bonds issued are also recognized in profit or loss using the effective interest rate method.

3.31 Current income tax and deferred

Corporate income tax for the year is determined as the sum of current and deferred income taxes from the different consolidated companies.

Current taxes are based on the application of the various types of taxes attributable to taxable income for the period. The Company periodically assesses the positions taken in the determination of taxes with respect to situations in which the applicable tax regulation is subject to interpretation and considers whether it is probable that a tax authority will accept an uncertain tax treatment. The Company measures its tax balances based on the most

likely

amount or expected value, depending on which method provides a better prediction of the resolution of uncertainty.

Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized.

In conformity with current tax regulations, the provision for corporate income tax and taxes on mining activity is recognized on an accrual basis, presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and associated credits. The balances of these accounts are presented in current income taxes recoverable or current taxes payable, as applicable.

F-42

Notes to the Consolidated Financial Statements  
December 31, 2021

Income tax and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in income or equity, considering the origin of the gains or losses which have generated them.

At each reporting period, the carrying amount of deferred tax assets is reviewed and recognized only if it is probable that future taxable amounts will be available to allow the recovery of all or a portion of the deferred tax assets.

With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used. The deferred taxes related to items directly recognized in equity is registered with effect on other comprehensive income and not with effect on income.

Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority.

The recognized deferred tax assets refer to the amount of income tax to recover in future periods, related to:

a) deductible temporary differences;

b) compensation for losses obtained in prior periods, which have not yet been subject to tax deduction; and

c) compensation for unused credits from prior periods.

The Company recognizes deferred tax assets when it has the certainty that they can be offset with tax income from subsequent periods, unused tax losses or credits to date, but only when this availability of future tax income is probable and can be used for offsetting these unused tax losses or credits.

The recognized deferred tax liabilities refer to the amount of income tax to pay in a future period, related to taxable temporary differences.

The Company does not recognize deferred tax liabilities in all cases of taxable temporary differences associated with investments in subsidiaries, branches and associates, or with joint ventures, because based on the standard, the two following conditions both apply:

(i) the parent company, investor or shareholder is capable of controlling the moment of the reversal of temporary differences; and

(ii) it is probable that the temporary difference will not be reversed in the foreseeable future.

Moreover, the Company does not recognize deferred tax assets for all the deductible temporary differences that originate from investments in subsidiaries, branches and associates, or from joint ventures, because it is unlikely that they meet the following requirements:

(i) temporary differences are reversed in the foreseeable future; and

(ii) there is taxable profit available against which temporary differences can be used.

3.32 Operating segment reporting

IFRS 8 requires that companies adopt a management approach to disclose information on the operations generated by its operating segments. In general, this is the information that management uses internally for the evaluation of segment performance and making the decision on how to allocate resources for this purpose.

An operating segment is a group of assets and operations responsible for providing products or services subject to risks and performance that are different from those of other business segments. A geographical segment is responsible for providing products or services in a given economic environment subject to risks and performance that are different from those of other segments operating in other economic environments.

Allocation of assets and liabilities, to each segment is not possible given that these are associated with more than one segment, except for depreciation, amortization and impairment of assets, which are directly allocated in accordance with the criteria established in the costing process for product inventories to the corresponding segments.

3.33 Primary accounting criteria, estimates and assumptions

Management is responsible for the information contained in these consolidated annual accounts, which expressly indicate that all the principles and criteria included in IFRS, as issued by the IASB, have been applied in full.

In preparing the consolidated financial statements of the Company and its subsidiaries, management has made significant judgments and estimates to quantify certain assets, liabilities, revenues, expenses and commitments included therein. Basically, these estimates refer to:

· Estimated useful lives are determined based on current facts and past experience and take into consideration the expected physical life of the asset, the potential for technological obsolescence, and regulations. (See Notes 3.20, 14 and 15).

· Impairment losses of certain assets - Goodwill and intangible assets that have an indefinite useful life are not amortized and are assessed for impairment on an annual basis, or more frequently if the events or changes in circumstances indicate that these may have deteriorated Other assets, including property, plant and equipment, exploration assets, goodwill and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their recoverable amounts. If an impairment assessment is required, the assessment of fair value or value in use often requires estimates and assumptions such as discount rates, exchange rates, commodity prices, future capital requirements and future operating performance. Changes in such estimates could impact the recoverable values of these assets. Estimates are reviewed regularly by management (See Notes 14 and 15).

· Assumptions used in calculating the actuarial amount of pension-related and severance indemnity payment benefit commitments (See Note 17).

· Contingencies – The amount recognized as a provision, including legal, contractual, constructive and other exposures or obligations, is the best estimate of the consideration required to settle the related liability, including any related interest charges, considering the risks and uncertainties surrounding the obligation. In addition, contingencies will only be resolved when one or more future events occur or fail to occur. Therefore, the assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. The Company assesses its liabilities and contingencies based upon the best information available, relevant tax laws and other appropriate requirements (See Note 20). If the Company is unable to rationally estimate the obligation or concluded no loss is probable but it is reasonably possible that a loss may be incurred, no provision is recorded but disclosed in the notes to the consolidated financial statements.

· Volume determination for certain in-process and finished products is based on topographical measurements and technical studies that cover the different variables (density for bulk inventories and density and porosity for the remaining stock, among others), and related allowance.

· Estimates for obsolescence provisions to ensure that the carrying value of inventory is not in excess of the net realizable Inventory valuation. (See Note 10).

Even though these estimates have been made on the basis of the best information available on the date of preparation of these consolidated financial statements, certain events may occur in the future and oblige their amendment (upwards or downwards) over the next few years, which would be made prospectively.

Note 4 Financial risk management

4.1 Financial risk management policy

The Company’s financial risk management policy is focused on safeguarding the stability and sustainability of the Company and its subsidiaries with regard to all such relevant financial uncertainty components.

The Company’s operations are subject to certain financial risk factors that may affect its financial position or results. The most significant risk exposures are market risk, liquidity risk, currency risk, credit risk, and interest rate risk, among others.

There could also be additional risks, which are either unknown or known but not currently deemed to be significant, which could also affect the Company’s business operations, its business, financial position, or profit or loss.

The financial risk management structure includes identifying, determining, analyzing, quantifying, measuring and controlling these events. Management and in particular, Finance Management, is responsible for constantly assessing the financial risk.

4.2 Risk Factors

(a) Credit risk

A global economic contraction may have potentially negative effects on the financial assets of the Company, which are primarily made up of financial investments and trade receivables, and the impact on of our customers could extend the payment terms of the Company's receivables by increasing its exposure to credit risk. Although measures are taken to minimize the risk, this global economic situation could mean losses with adverse material effects on the business, financial position or profit and loss of the Company's operations.

Trade receivables: to mitigate credit risk, the Company maintains active control of collection and requires the use of credit insurance. Credit insurance covers the risk of insolvency and unpaid invoices corresponding to 80% of all receivables with third parties. The credit risk associated with receivables is analyzed in Note 12.2 b) and the related accounting policy can be found in Note 3.6.

Bank Notes: These are negotiable promissory notes issued by a bank payable at maturity. They are accepted based on the credit quality of the issuing banks.

No significant modifications have been made during the period to risk models or parameters used in comparison to December 31, 2020, and no modifications have been made to contractual cash flows that have been significant during this period.

Financial investments: correspond to time deposits whose maturity date is greater than 90 days and less than 360 days from the date of investment, so they are not exposed to excessive market risks. The counterparty risk in implementation of financial operations is assessed on an ongoing basis for all financial institutions in which the Company holds financial investments.

The credit quality of financial assets that are not past due or impaired can be evaluated by reference to external credit ratings (if they are available) or historical information on counterparty late payment rates:

(b) Currency risk

The functional currency of the company is the US dollar, due to its influence on the determination of price levels, its relation to the cost of sales and considering that a significant part of the Company’s business is conducted in this currency. However, the global nature of the Company's business generates an exposure to exchange rate variations of several currencies with the US dollar. Therefore, the Company maintains hedge contracts to mitigate the exposure generated by its main mismatches (net between assets and liabilities) in currencies other than the US dollar against the exchange rate variation, updating these contracts periodically depending on the amount of mismatching to be covered in these currencies. Occasionally, subject to the approval of the Board, the Company ensures short-term cash flows from certain specific line items in currencies other than the US dollar.

A significant portion of the Company’s costs, especially salary payments, is associated with the Peso. Therefore, an increase or decrease in its exchange rate with the US dollar will provoke a respective decrease or increase to these accounting costs, which would be reflected in the Company’s profit and loss. By the fourth quarter of 2021, approximately US$ 530 million accumulated in expenses are associated with the Peso.

As of December 31, 2021, the Company held derivative instruments classified as hedges of foreign exchange risks associated with 100% of all of the bond liabilities denominated in UF, for a liability at fair value of US$ 81.85 million, this significant variation is explained primarily by the USD/CLP exchange rate observed at the end of the period. As of December 31, 2020, an asset was recognized amounting to US$ 18.41 million.

Furthermore, on of December 31, 2021, the Company held derivative instruments classified as hedges of foreign exchange risks associated with 100% of all nominative term deposits in UF and in pesos, at a fair value of US$ 12.61 million in assets. On December 31, 2020, a liability was recognized for an amount of US$ 21 million.

The Company had the following derivative contracts as of December 31, 2021 (at the absolute value of the sum of their notional values), to hedge the difference between its assets and liabilities: US$ 85.25 CLP/US dollar derivative contracts, US$ 60.98 Euro/US dollar derivative contracts, US$ 37.07 million in South African rand/US dollar derivative contracts, US$ 207.64 million in Chinese renminbi/US dollar derivative contracts, US$ 57.51 million in Australian dollar/US dollar derivative contracts and US$ 11.95 million in other currencies.

(c) Interest rate risk

Interest rate fluctuations, primarily due to the uncertain future behavior of markets, may have a material impact on the financial results of the Company. Significant increases in the rate could make it difficult to access financing at attractive rates for the Company's investment projects.

The Company maintains current and non-current financial debt at fixed rates and LIBOR rate plus spread.

As of December 31, 2021, the Company has 2.7% of its financial liabilities linked to variations in the LIBOR rate. 100% of these obligations are covered by derivative instruments classified as interest rate hedging; therefore, a significant rate increase would not impact our financial condition.

(d) Liquidity risk

Liquidity risk relates to the funds needed to comply with payment obligations. The Company’s objective is to maintain financial flexibility through a comfortable balance between fund requirements and cash flows from regular business operations, bank borrowings, bonds, short term investments, and marketable securities, among others. For this purpose, the Company keeps a high liquidity ratio

1

, which enables it to cover current obligations with clearance. (As of December 31, 2021 this was 4.76 and 5.40 for December 31, 2020).

The Company has an important capital expense program which is subject to change over time.

On the other hand, world financial markets go through periods of contraction and expansion that are unforeseeable in the long-term and may affect The Company’s access to financial resources. Such factors may have a material adverse impact on the Company’s business, financial position and results of operations.

The Company constantly monitors the matching of its obligations with its investments, taking due care of maturities of both, from a conservative perspective, as part of this financial risk management strategy. As of December 31, 2021, the Company had unused, available revolving credit facilities with banks, for a total of US$ 489 million.

The position in other cash and cash equivalents are invested in highly liquid mutual funds with an AAA risk rating.

1 All current assets divided by all current liabilities.

Pursuant to Article 99 of the Securities Market Law, the CMF may determine that a company does not have a controlling entity in accordance with the distribution and dispersion of its ownership. On November 30, 2018, the CMF issued the ordinary letter No. 32,131 whereby it determined that the Pampa Group do not exert decisive power over the management of the Company since it does not have a predominance in the ownership that allows it to make management decisions. Therefore, the CMF has determined not to consider Pampa Group the controlling entity of the Company and that the Company does not have a controlling entity given its current ownership structure.

(1) There are three types of Lower Value Provisions: (a) Economic Realizable Lower Value, (b) Potential Inventory with Uncertain Future Use and (c) Reprocessing Costs of Off-Specification Products.

(2) Provisions for Inventory Differences generated when physical differences are detected when taking inventory, which exceed the tolerance levels for this process.

(3) This algorithm corresponds to the provision of diverse percentages based on the complexity in the measurement and rotation of stock, as well as standard differences based on previous results, as is the case with provisions relating to Commercial Offices.

Effectiveness

The Company uses cross currency swap derivative instruments to hedge the possible financial risk associated with the volatility of the exchange rate associated with Chilean pesos and UF. The objective is to hedge the exchange rate and inflation financial risks associated with bonds payable. Hedges are documented and tested to measure their effectiveness.

Based on a comparison of critical terms, hedging is highly effective, given that the hedged amount is consistent with obligations maintained for bonds denominated in Pesos and UF. Likewise, hedging contracts are denominated in the same currencies and have the same maturity dates of bond principal and interest payments.

12.7 Fair value measurement of finance assets and liabilities

The fair value hierarchy is detailed as follows:

(a) Level 1: The fair value of financial instruments traded in active markets (such as equity securities) is based on quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date . The quoted market price used for financial assets held by the Company is the current bid price. These instruments are included in level 1.

(b) Level 2: The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined using valuation techniques which maximize the use of observable market inputs and rely as little as possible on entity-specific estimates. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable  for the asset or liability, either directly or indirectly .

(c) Level 3: If one or more of the significant inputs is not based on observable market data  for the asset or liability , the instrument is included in level 3. This is the case for unlisted equity securities.

12.8 Estimated fair value of financial instruments

The fair value of financial assets and liabilities is estimated using the following information. Although the data represent Management's best estimates, it is subjective and involves significant estimates regarding current economic conditions, market conditions and risk characteristics.

Methodologies and assumptions used depend on the risk terms and characteristics of instruments and include the following as a summary:

Fair value estimation for

recognition purposes

Financial assets and liabilities measured at fair value consist of forwards hedging the mismatch in the balance sheet and cash flows, options hedging the mismatch in the balance sheet and cross currency swaps to hedge bonds issued in local currency (Peso/UF).

The fair value of the Company’s assets and liabilities recognized by cross currency swaps contracts is calculated as the difference between the present value of discounted cash flows of the asset (Peso/UF) and liability (Dollar) parts of the derivative. In the case of the IRS, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Financial options: the value recognized is calculated using the Black-Scholes method.

In the case of CCS, the entry data used for the valuation models are UF, Peso, Dollar and basis swap rates. In the case of fair value calculations for interest rate swaps, the Forward Rate Agreement rate and ICVS 23 Curve (Bloomberg: cash/deposits rates, futures, swaps). In the case of forwards, the forwards curve for the currency in question is used. Finally, for options, the spot price, risk-free rate and volatility of exchange rate are used, all in accordance with the currencies used in each valuation. The financial information used as entry data for the Company’s valuation models is obtained from Bloomberg, the well-known financial software company. Conversely, the fair value provided by the counterparties of derivatives contracts is used only as a control and not for valuation.

The effects on profit or loss of movements in these amounts is recognized in the caption finance costs, foreign currency translation gain (loss) or cash flow hedge reserve in the statement of comprehensive income, depending on each particular case.

Estimate of fair value for

disclosure

purposes

· Cash equivalent approximates fair value due to the short-term maturities of these instruments.

· The fair value of current trade receivables is considered to be equal to the carrying amount due to the maturity of such accounts at short-term.

· Payables, current lease liabilities and other current financial liabilities are considered fair value equal to book value due to the short-term maturity of these accounts.

· The fair value of the debt (long-term secured and unsecured debentures; bonds denominated in local currency (Peso/UF) and foreign currency (Dollar), borrowings denominated in foreign currency (Dollar) and lease liabilities of the Company are calculated at current value of cash flows subtracted from market rates upon valuation, considering the terms of maturity and exchange rates. The UF and Peso rate curves are used as inputs for the valuation model. This information is obtained through from the renowned financial software company, Bloomberg, and the Chilean Association of Banks and Financial Institutions.

The Company’s lease activities included the following aspects:

(a) The nature of the Company’s lease activities is related to contracts focused primarily on business operations, mainly rights-of-use to equipment and real estate,

(b) The Company does not estimate any significant future cash outflows that would potentially expose the Company, and these are likewise not reflected in the measurement of lease liabilities, related to concepts such as: (i) Variable lease payments, (ii) Extennsion options and termination options, (iii) Guaranteed residual value and (iv) Leases not yet undertaken but committed by the Company.

(c) These are not subject to restrictions or agreements imposed by contracts.

There were no sales transactions with leases later in the period.

(a)       

Not economically feasible

: Exploration and evaluation disbursements, once finalized and concluded to be not economically feasible, will be charged to profit and loss. As of December 31, 2021, and 2020 there were no disbursements for this concept.

(b)       

Execution:

Disbursements for exploration and evaluation under implementation and therefore prior to determination of economic feasibility, are presented as part of property, plant and equipment as constructions in progress.

17.2 Policies on defined benefit plan

This policy is applied to all benefits received for services provided by the Company's employees. This is divided as follows:

a) Short-term benefits for active employees are represented by salaries, social welfare benefits, paid time off, sickness and other types of leave, profit sharing and incentives and non-monetary benefits; e.g., healthcare service, housing, subsidized or free goods or services. These will be paid in a term which does not exceed twelve months. The Company maintains incentive programs for its employees, which are calculated based on the net result at the close of each period by applying a factor obtained from an evaluation based on their personal performance, the Company’s performance and other short-term and long-term indicators.

b) Staff severance indemnities are agreed and payable based on the final salary, calculated in accordance with each year of service to the Company, with certain maximum limits in respect of either the number of years or in monetary terms. In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and there are a number of different circumstances through which a person can be eligible for it, as indicated in the respective agreements; e.g. retirement, dismissal, voluntary retirement, incapacity or disability, death, etc. See Note 17.3.

c) Obligations after employee retirement, described in Note 17.4.

d) Retention bonuses for a group of Company executives, described in Note 17.6.

F-126

Notes to the Consolidated Financial Statements  
December 31, 2021

17.3 Other long-term benefits

The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees.

Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, without establishing a separate fund with specific assets, which is referred to as

not funded

.

Benefit payment conditions

The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system as established in Decree Law 3,500 of 1980.

Methodology

The determination of the defined benefit obligation is made under the requirements of IAS 19 “Employee benefits”.

17.4 Post-employment benefit obligations

Our subsidiary SQM NA, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”. This obligation is calculated measuring the expected future forecast staff severance indemnity obligation using a net salary gradual rate of restatements for inflation, mortality and turnover assumptions, discounting the resulting amounts at present value using the interest rate defined by the authorities.

Since 2003, SQM NA offers benefits related to pension plans based on the 401-K system to its employees, which do not generate obligations for the Company.

Sensitivity relates to an increase/decrease of 100 basis points.

17.6 Executive compensation plan

The Company currently has a compensation plan with the purpose of motivating the Company’s executives and encouraging them to remain with the Company, by granting payments based on the change in the price of SQM’s shares. There is a partial payment of the share benefit program in the event of termination of the contract for causes other than the resignation and application of Article 160 of the Labor Code.

(a) Plan characteristics

This compensation plan is related to the Company’s performance through the SQM Series B share price (Santiago Stock Exchange).

(b) Plan participants

The compensation plan considers 29 Company executives, who are entitled to this benefit, provided that they stay with the Company until a given date, recognizing on an accrual basis: a) a 2021 bonus, which will be made effective by paying 146,708 shares distributed between the four quarters of 2021, and b) a 2022 bonus for 42,032 shares, which will be made effective the first quarter of 2023.

Compensation

The compensation payable to each executive is calculated by multiplying:

i) the average price of the series B shares on the Santiago Stock Exchange during the fourth quarter of 2020, in its US dollar equivalent (with a value of US$ 41.93 per share).

ii) the average price of SQM’s series B shares during the final quarter of 2022, subject to a limit of US$ 54 per share.

i ii ) By a number equal to the quantity of shares that have been individually assigned to each executive included in the plan.

This compensation plan was approved by the Company’s Board of Directors and its application started on September 30, 2020.

The plan that was in place on December 31, 2020 considered 177,905 and 188,740 shares, for 2021. The effects on the income statement are equivalent to an expense of ThUS$ 5,979 and ThUS$ 875 in the income statement for the periods ending December 3

(1) Payment Obligations for the lease contract with CORFO: These correspond to obligations assumed in the Lease Agreement. Our subsidiary SQM Salar holds exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement and the Project Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo’s rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030. On January 17, 2018, SQM and CORFO reached an agreement to end an arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce and other cases related to it.

The agreement signed in January 2018, includes important amendments to the lease agreement and project agreement signed between CORFO and SQM in 1993. The main modifications became effective on April 10, 2018 and requires an increase in the lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. This agreement has been amended since it was signed, and it is reasonable to expect that it will continue to be amended as mutually agreed by the parties.

Additionally, SQM Salar commits to contribute to research and development efforts, as well as to the communities in close proximity to the Salar de Atacama and provide a percentage of total annual sales of SQM Salar to regional development.

SQM Salar commits to contribute between US$10.8 million and US$18.9 million per year to research and development efforts, between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and 1.7% of total annual sales of SQM Salar to regional development

Note 19 Disclosures on equity

The detail and movements in the funds of equity accounts are shown in the consolidated statement of changes in equity.

19.1 Capital management

The main object of capital management relative to the administration of the Company’s financial debt and equity is to ensure the regular conduct of operations and business continuity in the long term, with the constant intention of maintaining an adequate level of liquidity and in compliance with the financial safeguards established in the debt contracts in force. Within this framework, decisions are made in order to maximize the value of the company.

Capital management must comply with, among others, the limits contemplated in the Financing Policy approved by the Shareholders’ Meeting, which establish a maximum consolidated indebtedness level of 1.5 times the debt to equity ratio. This limit can be exceeded only if the Company’s management has first obtained express approval at an Extraordinary Shareholders’ Meeting.

The Company’s management controls capital management based on the following ratios:

Capital Management	As of December 31, 2021			As of December 31, 2020			Description (1)	Calculation (1)
Net Financial Debt (ThUS$)		204,692			1,074,020		Financial Debt – Financial Resources	Other current Financial Liabilities + Other Non-Current Financial Liabilities– Cash and Cash Equivalents – Other Current Financial Assets – Hedging Assets, non-current
Liquidity		4.62			5.40		Current Assets divided by Current Liabilities	Total Current Assets / Total Current Liabilities
ROE		18.41	%		7.79	%	Profit for the year divided by Total Equity	Profit for the year / Equity
Adjusted EBITDA (ThUS$)		1,185,453			579,765		Adjusted EBITDA	Profit (loss) + Depreciation and Amortization Expenses adjustments + Finance Costs + Income Tax – Other income and Share of profit of associates and joint ventures + Other expenses by function – Finance income – Currency differences
EBITDA (ThUS$)		1,140,086			524,650		EBITDA	Profit (loss) + Depreciation and Amortization Expense adjustments + Finance Costs + Income Tax
ROA		21.29	%		9.83	%	Adjusted EBITDA – Depreciation divided by Total Assets net of financial resources less related parties’ investments	(Gross Profit – Administrative Expenses)/ (Total Assets – Cash and Cash Equivalents – Other Current Financial Assets – Other Non-Current Financial Assets – Equity accounted Investments) (LTM)
Indebtedness		0.06			0.50		Net Financial Debt on Equity	Net Financial Debt / Total Equity

The Company’s capital requirements change according to variables such as: working capital needs, new investment financing and dividends, among others. The SQM Group manages its capital structure and makes adjustments bases on the predominant economic conditions so as to mitigate the risks associated with adverse market conditions and take advantage of the opportunities there may be to improve the liquidity position of the SQM Group.

There have been no changes in the capital management objectives or policy within the years reported in this document, no breaches of external requirements of capital imposed have been recorded. There are 0contractual capital investment commitments.

19.2 Operational restrictions and financial limits

Bond issuance contracts in the local market require the Company to maintain a Total Borrowing Ratio no higher than 1 for Series H, Series O and Series Q bonds, calculated over the last consecutive 12 months.

Capital management must ensure that the Borrowing Ratio remains below 1.0, with respect to the Series H, Series O and Series Q bonds. This ratio was redefined at the Bondholders' Meeting held in September 2020, as the result of dividing Net Financial Debt by the company's Total Equity. Previously it had been defined as Total Liabilities divided by Equity, and the limit for this ratio was 1.44, with a prepayment option for bondholders if this ratio rose above 1.2. As of December 31,

 2021 and 2020

this ratio was 0.06.

19.5 Dividend policies

As required by Article 79 of the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued and subscribed shares, a publicly traded corporation must annually distribute a cash dividend to its shareholders, prorated based on their shares or the proportion established in the company’s bylaws if there are preferred shares, with at least 30% of our consolidated profit for each year.

Dividend policy for commercial year 2021

Company’s dividend policy for the 2021 business year was agreed upon by the Board of Directors on April 23, 2021. This dividend policy was amended on November 17, 2021, and establishes the following:

(a) Distribute and pay to the corresponding shareholders, a percentage of the net income that shall be determined per the following financial parameters as a final dividend:

(i) 100% of the profit for 2021 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 2.5 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 0.85 times.

(ii) 80% of the profit for 2021 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 2.0 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 0.95 times.

(iii) 60% of the profit for 2021 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 1.5 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 1.05 times.

F-137

Notes to the Consolidated Financial Statements  
December 31, 2021

(iv) If none of the foregoing financial parameters are met, the Company shall distribute and pay, as a final dividend, and in favor of the respective shareholders, 50% of the 2021 net income.

(b) Distribute and pay two interim dividends during 2021, which will be charged to the final dividend indicated above against retained earnings reflected in the financial statements as of March 31, 2021 and June 30, 2021, by the percentage that corresponds according to the financial parameters expressed in (a) above.

On May 19, 2021 and August 18, 2021, the Board of Directors agreed to distribute and pay an interim dividend equivalent to US$ 0.23797 per share and US$ 0.31439 per share, respectively, out of the Company's earnings for 2021. These amounts were paid in Chilean peso equivalents at the official US dollar exchange rate on May 28, 2021 and September 1, 2021, respectively (the "Interim Dividends")

(c) The Board of Directors will not distribute any other interim dividends out of 2021 earnings.

(d) At the ordinary meeting to be held in 2022, the Company's Board of Directors will propose a final dividend in line with the percentage corresponding to the financial parameters outlined in (a) above, discounting the provisional dividends and the Interim Dividends. In the event that the amount equivalent to the percentage of the 2021 distributable earnings as described in (a) above is equal to or less than the sum of the Potential Dividend and the Interim Dividends, then no additional amount will be distributed and the Interim Dividends will be deemed to be paid as a final dividend. In any case, the final dividend may not be less than the minimum legal dividend required by law or the bylaws.

(e) Any remaining amount from the net profits from 2021 can be retained and used to finance the Company’s own operations or one or more of its investment projects, notwithstanding a possible distribution of dividends charged to accumulated profit that might be approved by the shareholders’ meeting or the possible future capitalization of all or part of it.

(f) The payment of additional dividends is not being considered.

It must be expressly stated that this dividends policy details the intention of the Company’s Board of Directors and its fulfillment depends on the actual profits obtained, as well as on the results indicated by the projections the Company makes from time to time or on the existence of particular conditions, as appropriate. In any case, if the dividend policy set forth by the Board of Directors should undergo any substantial change, the Company must communicate it as a material event.

(i) The company Arrigoni Ingeniería y Construcción S.A. filed a claim in November 2019 against SQM Salar in arbitration court under CAM rules, requesting the conclusion of the Works Contract known as “Expansion of Lithium Carbonate Plant Phase II.” The trial is currently in the evidence stage. The amount of the claim is close to MUS$ 14.6.

(j) The Company has initiated an arbitration process against the company Sierra Gorda S.C.M. due to controversies originating from the Mining, Royalties and Other Sales Contract dated December 16, 2011. Sierra Gorda S.C.M. has filed counterclaims against the Company. The process is in its evidence stage. The counterclaims filed against the Company amount to MUS$ 46.

(k) Through resolution dated April 14, 2020, the General Water Bureau (DGA) fined SQM Salar S.A. an amount of 4,180 UTM for the alleged violation of article 294 of the Water Code. This resolution was appealed for reconsideration as established in article 136 of the Water Code, and its resolution is currently pending.

(l) On January 7, 2021, the Company Ocaña y Vega Limited has requested arbitration against the Company to claim compensation for damages associated with the early termination of two construction contracts. The case has reached the evidence gathering stage. The cost of arbitration is valued at approximately ThUS$ 377.

(m) On April 6, 2021, Empresa Eléctrica Cochrane SpA requested the constitution of arbitration to resolve a dispute in relation to electricity supply contracts signed on March 30, 2012, and February 1, 2013. The trial is currently in the discussion stage. On January 17, 2022, the Company filed a claim for early termination of the electricity supply contracts against Empresa Eléctrica Cochrane SpA. at the same arbitration tribunal.

(n) In October 2021, the Company requested the constitution of an arbitration against Chilena Consolidada Seguros Generales S.A. to resolve differences in relation to the interpretation and execution of the directors' and officers' liability insurance policy. The lawsuit has been notified to the arbitrator.

(o) In February 2022, the company Montajes Eléctricos y Construcciones RER Limitada filed a claim for damages before the 21st Civil Court of Santiago against SQM Industrial S.A. for its alleged liability derived from the breach of an electrical installation contract. The case is still in the discussion stage. The amount of the lawsuit is approximately ThUS$ 542.

The Company and its subsidiaries have been involved and will probably continue to be involved either as plaintiffs or defendants in certain judicial proceedings that have been and will be heard by the arbitration or ordinary courts of justice that will make the final decision. Those proceedings that are regulated by the appropriate legal regulations are intended to exercise or oppose certain actions or exceptions related to certain mining claims either granted or to be granted and that do not or will not affect in an essential manner the development of the Company and its subsidiaries.

Soquimich Comercial S.A. has been involved and will probably continue being involved either as plaintiff or defendant in certain judicial proceedings through which it intends to collect and receive the amounts owed, the total nominal value of which is approximately MUS$ 1.05.

The Company and its subsidiaries have made efforts and continues making efforts to obtain payment of certain amounts that are still owed to the Company due to its activities. Such amounts will continue to be required using judicial or non-judicial means by the plaintiffs, and the actions and exercise related to these are currently in full force and effect.

20.2 Environmental contingencies

The SMA issued a resolution dated November 28, 2016, rectified by a resolution dated December 23, 2016, which filed charges against SQM Salar for brine extraction in excess of authorized amounts, progressive impairment of the vitality of carob trees, providing incomplete information modification of follow-up plan variables, and other charges. SQM Salar S.A. presented a compliance program that was accepted by the SMA. On December 2019, the Environmental Court of Antofagasta rendered the accepted compliance program null. In October 2020, the SMA formulated new observations for the compliance program, which will enable the incorporation of improvements in line with the ruling of the Environmental Court of Antofagasta, to then make a determination regarding approval or rejection. If a new compliance program is not approved by the SMA, or if approved and legally challenged and rendered null and void by the Chilean courts, the sanction process against SQM Salar could be resumed. This latter event may consider the application of fines up to MUS$9, temporary or permanent closure of facilities and in extreme circumstances, revocation of the respective environmental permit.

20.3 Tax Contingencies

SQM Salar has filed three tax claims against the SII for taxes levied between tax years 2012 and 2018 (business years 2011 to 2017). The SII has sought to broaden the application of the specific tax on mining activities to the extraction of lithium, a substance that is not concessionable by law. The amount associated with these processes totals US$ 90.4 million, which has been paid by SQM Salar. This amount is recorded under “Non-current tax assets” in the Consolidated

Statement of Financial Position

of the Company as of December 3

1

, 2021 and 2020.

The non-current tax assets presented in the Company’s Financial Statements as of December 31, 2021 of US$ 90.4 million, correspond to the three claims in the recently mentioned dispute. This amount can be broken down as follows: overcharged amount of US$ 18.9 million; potential specific tax for lithium amounting to US$ 48.6 million (minus effect on first category income tax) and interests associated with this tax for US$ 22.8 million.

The details of the claims can be found below:

(a) On August 26, 2016, a tax claim was filed with the Third Tax and Customs Court of the Metropolitan Region against tax assessments No. 169, 170, 171 and 172 for tax years 2012 to 2014. The amount in dispute is US$ 17.8 million, of which (i) US$ 11.5 million correspond to the contested tax (minus effect on first category income tax), and (ii) US$ 6.3 million correspond to interest and associated fines. On November 28, 2018, the Third Tax and Customs Court rejected the claim, and the case is currently in the Santiago Court of Appeals.

(b) On March 24, 2017, a tax claim was filed with the Third Tax and Customs Court of the Metropolitan Region against tax assessment No. 207 and resolution No. 156, both issued by the SII, for tax years 2015 to 2016. The amount in dispute is US$ 8.6 million, of which (i) US$ 1.3 million correspond to amounts assessed in excess, (ii) US$ 6.9 million correspond to the contested tax (minus effect on first category income tax), and (ii) US$ 0.5 million correspond to interest and fines. On November 28, 2018, the Third Tax and Customs Court rejected the corresponding claim, and the case is currently in the Santiago Court of Appeals.

December 31, 2021

(c) On July 15, 2021, SQM Salar filed a public right annulment suit and tax claim with the First Tax and Customs Court of the Metropolitan Region against tax assessments No. 65 and 66 for the 2017 and 2018 tax years. The amount in dispute is US$ 63.9 million, of which (i) US$ 17.7 million correspond to overcharged amounts, (ii) US$ 30.2 million correspond to the contested tax (minus effect on first category income tax), and (iii) US$ 16.1 million correspond to interest and fines. This case is under deliberation.

The SII has not issued an assessment claiming differences in the specific tax on mining activities filed for tax years 2019 onward. If the SII uses criteria similar to that used in previous years, it may issue an assessment in the future for this period. The Company estimates a potential assessment of US$ 79.8 million (minus effect on first category income tax) by the SII, without considering interests and fines.

To date, the Company has recorded no effect corresponding to this tax on its profit and loss.

20.4 Contingencies regarding to the Contracts with Corfo

On September 6, 2018, representatives Claudia Nathalie Mix Jiménez, Gael Fernanda Yeomans Araya and Camila Ruslay Rojas Valderrama and the Poder Ciudadano political party filed an annulment suit against Corfo, which requested that the Salar de Atacama Project Agreement between Corfo and the Company, SQM Potasio and SQM Salar be annulled. The Companies have taken part of the process as interested third parties.

In the event that the annulment claim is approved for the Salar de Atacama Project Agreement, SQM Salar may be prevented from the exploitation of the mining assets in the Salar de Atacama that it has leased from Corfo.

20.5 Contingencies associated with conflicts between shareholders of the Abu Dhabi Fertilizer Industries Company

Due to differences between shareholders of the company Abu Dhabi Fertilizer Industries Company, diverse lawsuits have arisen that may result in claims against SQM Corporation N.V. and by this company against the other shareholders. These disputes may materially affect the value of the investment of the Company in Abu Dhabi Fertilizer Industries Company. At this time, it is not possible to quantify the amounts of these claims.

20.6 Restricted or pledged cash

The subsidiary Isapre Norte Grande Ltda., in compliance with the provisions established by the Chilean Superintendence of Healthcare, which regulates the running of pension-related health institutions, maintains a guarantee in financial instruments delivered in deposits, custody and administration to Banco de Chile.

This guarantee, according to the regulations issued by the Chilean Superintendence of Healthcare is equivalent to the total amount owed to its members and medical providers, Banco de Chile reports the present value of the guarantee to the Chilean Superintendence of Healthcare and Isapre Norte Grande Ltda on a daily basis. As of December 31, 2021, the guarantee amounts to ThUS$ 622.

Note 22 Reportable segments

22.1 Reportable segments

(a) General information:

The amount of each item presented in each operating segment is equal to that reported to the highest authority that makes decisions regarding the operation, in order to decide on the allocation of resources to the defined segments and to assess its performance.

These operating segments mentioned are consistent with the way the Company is managed and how results will be reported by the Company. These segments reflect separate operating results that are regularly reviewed by the executive responsible for operational decisions in order to make decisions about the resources to be allocated to the segment and assess its performance (See Note 22.2).

The performance of each segment is measured based on net income and revenues. Inter-segment sales are made using terms and conditions at current market rates.

(b) Factors used to identify segments on which a report should be presented:

The segments covered in the report are strategic business units that offer different products and services. These are managed separately because each business requires different technology and marketing strategies.

(c) Description of the types of products and services from which each reportable segment obtains its income from ordinary activities

The operating segments, which obtain income from ordinary activities, generate expenses and have its operating results reviewed on a regular basis by the highest authority who makes decisions regarding operations, relate to the following groups of products:

(i) Specialty plant nutrients

(ii) Iodine and its derivatives

(iii) Lithium and its derivatives

(iv) Industrial chemicals

(v) Potassium

(vi) Other products and services

(d) Description of income sources for all the other segments

Information regarding assets, liabilities, profits and expenses that cannot be assigned to the segments indicated above, due to the nature of production processes, is included under the "Unallocated amounts” category of the disclosed information.

F-150

Notes to the Consolidated Financial Statements  
December 31, 2021

(e) Description of the nature of the differences between measurements of results of reportable segments and the result of the entity before the expense or income tax expense of incomes and discontinued operations

The information reported in the segments is extracted from the Company’s consolidated financial statements and therefore there is no need to prepare reconciliations between the data mentioned above and those reported in the respective segments, according to what is stated in paragraph 28 of IFRS 8, "Operating Segments".

For the allocation of inventory valuation costs, we identify the direct expenses (can be directly allocated to products) and the common expenses (belong to coproduction processes, for example common leaching expenses for production of Iodine and Nitrates), Direct costs are directly allocated to the product and the common costs are distributed according to percentages that consider different variables in their determination, such as margins, rotation of inventories, revenue, production etc.

The allocation of other common costs that are not included in the inventory valuation process, but go straight to the cost of sales, use similar criteria: the costs associated with a product or sales in particular are assigned to that particular product or sales, and the common costs associated with different products or business lines are allocated according to the sales.

(f) Description of the nature of the differences between measurements of assets of reportable segments and the Company´s assets

Assets are not shown classified by segments, as this information is not readily available, some of these assets are not separable by the type of activity by which they are affected since this information is not used by management in decision-making with respect to resources to be allocated to each defined segment. All assets are disclosed in the "unallocated amounts" category.

(g) Description of the nature of the differences between measurements of liabilities of reportable segments and the Company’s liabilities

Liabilities are not shown classified by segments, as this information is not readily available, some of these liabilities are not separable by the type of activity by which they are affected, since this information is not used by management in decision-making regarding resources to be allocated to each defined segment. All liabilities are disclosed in the "unallocated amounts" category.

(i) Explanation of the relationship between (expense) benefit for tax purposes and accounting income.

Based on IAS 12, paragraph 81, letter “c”, the company has estimated that the method that discloses the most significant information for users of the financial statements is the numeric conciliation between the tax benefit (expense) and the result of multiplying the accounting profit by the current rate in Chile. The aforementioned choice is based on the fact that the Company and subsidiaries established in Chile generate a large part of the Company’s tax benefit (expense). The amounts provided by subsidiaries established outside Chile have no relative importance in the overall context.
