You should carefully consider the risks and uncertainties described below, together with all other information contained in this annual report, before making any investment decision. Any of these risks and uncertainties could have a material adverse effect on Ternium's business, financial condition and results of operations, which could in turn affect the price of the Company’s shares and ADSs.

Risks Relating to the Steel Industry

A downturn in global or regional economic activity would cause a reduction in worldwide or regional demand for steel, which would have a material adverse effect on the steel industry and Ternium.

Steel demand is sensitive to trends in cyclical industries, such as the construction, automotive, appliance and machinery industries, which are significant markets for Ternium’s products and are also affected by national, regional or global economic conditions. A downturn in economic activity would reduce demand for steel products. This would have a negative effect on Ternium’s business and results of operations. A recession or depression affecting developed economies, or slower growth or recessionary conditions in emerging economies would exact a heavy toll on the steel industry and adversely affect our business and results of operations.

In 2020 the rapid expansion of the SARS-CoV-2 virus, the surfacing of new strains of the virus in several countries, and the containment measures adopted by governmental authorities triggered a severe fall in global economic activity and precipitated an unprecedented worldwide crisis. We took prompt action to mitigate the impact of the crisis and to adapt our operations on a country-by-country basis to comply with applicable rules and requirements. Although such measures proved to be successful to mitigate the impact of the crisis on us, and most restrictions imposed in connection with the COVID-19 pandemic have been lifted or relaxed in the countries where Ternium operates, if the virus continues to mutate and spread and new preventive measures are imposed in the future, our operations could be further affected adversely impacting our results. In addition, although global activity levels started to improve during the second half of 2020 and steel demand recovered to pre-COVID levels in 2021, there remains considerable uncertainty about the future duration and extent of the pandemic with new and more contagious variants of the SARS-CoV-2 virus appearing as well as about the effectiveness of available vaccines and the success of vaccination campaigns. In this uncertain environment our results of operations and financial condition could still be severely affected. For further information on the impact of the COVID-19 pandemic and measures adopted in connection therewith, see note 29 “The COVID-19 pandemic and its impact on Ternium” of our audited consolidated financial statements included in this annual report.

A protracted fall in steel prices or price volatility would have a material adverse effect on the results of Ternium.

Steel prices are volatile and are sensitive to trends in steel demand and raw material costs, such as steel scrap, iron ore and metallurgical coal costs. Historically, the length and nature of business cycles affecting steel demand and raw

7

material costs have been unpredictable. For example, U.S. steel prices trended down during most of 2018 and 2019, after peaking during the first half of 2018, as a result of softer steel consumption, increased steel production and, in 2019, lower costs of steel scrap. Steel prices decreased further in 2020 during the early stages of the COVID-19 pandemic reflecting a depression in steel consumption. However, after an initial slump, steel prices increased steadily during the rest of 2020 and picked at historical record levels in September 2021, as the speed of the recovery in steel production and in the production of steelmaking raw materials fell short of steel demand. Since then, steel prices decreased rapidly under a normalizing steel supply-demand balance scenario until February 2022, when they raised significantly following the start of the Russia-Ukraine armed conflict. A protracted fall in steel prices could adversely affect Ternium’s operating results by means of lower revenues and, eventually, could lead to inventory write-downs.

Even if raw material costs declined, the resulting reduction in steel production costs would not be immediately reflected in Ternium’s operating results as Ternium would first consume existing inventories acquired prior to such raw material cost decrease. In addition, Ternium may be unable to recover, in whole or in part, increased costs of raw materials and energy through increased selling prices on its products, or it may take an extended period of time to do so.

Regional or worldwide excess steel production capacity may lead to unfair trade practices in the international steel markets and/or to intense competition, hampering Ternium’s ability to sustain adequate profitability.

The steel industry is affected by economic cycles, as well as by regional or worldwide production overcapacity. Historically, the steel industry has suffered, especially on downturn cycles, from substantial over-capacity. In the last decade, over-capacity was particularly severe in China. More recently, there are several new steel making and steel processing facilities under construction or ramping-up in North America, which could contribute to an excess of steel production capacity in the coming years in the region. For further information on Ternium’s competition in the Mexican market see Item 4. “Information on the Company—B. Business Overview—Competition —Steel—Mexico”.

Excess steel production capacity may require several years to be absorbed by demand and, as a consequence, may contribute to an extended period of depressed margins and industry weakness. International trade of steel products conducted under unfair conditions increases particularly during downturn cycles and as a result of production over-capacity. Unfair trade practices may result in the imposition by some countries (that are significant producers and consumers of steel) of antidumping and countervailing duties or other trade measures and may cause fluctuations in international steel trade. The imposition of such trade remedies or temporary tariffs on major steel exporters in significant steel producing countries could in turn exacerbate pressures in other markets, including those in which Ternium operates, as exporters target such other markets to compensate, at least partially, for the loss of business resulting from the imposition of trade remedies or tariffs.

China is the largest steel producing country in the world, accounting for approximately 60% of worldwide crude steel production, and Chinese exports of steel products, including exports to Europe, the United States and Mexico, were subject to the imposition of antidumping and countervailing duties and other trade measures. A decrease in steel consumption in China in the future, including as a result of new variants of the SARS-CoV-2 virus appearing, could stimulate aggressive Chinese steel export offers, exerting downward pressure on sales and margins of steel companies operating in other markets and regions, including those in which Ternium operates. Similarly, a downturn in global or regional economic activity could encourage unfair steel trade practices adversely affecting Ternium’s business and results of operations. For further information, see Item 4. “Information on the Company—B. Business Overview—Regulations—Trade Regulations".

Sales may fall as a result of fluctuations in industry inventory levels or disruptions in Ternium customers’ supply chains.

Inventory levels of steel products held by companies that purchase Ternium’s products can vary significantly from period to period, as customers draw from existing inventory during periods of low investment in construction and other industry sectors that purchase Ternium’s products and accumulate inventory during periods of high investment. As a result, such companies may not purchase additional steel products or maintain their regular purchasing volume. In addition, disruptions in the industry’s supply chain could reduce the demand for Ternium’s products. For example, in 2021 vehicle production was severely affected by a shortage of semiconductors that, in turn, affected Ternium’s steel sales. Fluctuations in steel inventory levels and disruptions in Ternium customers’ supply chains can temporarily affect the demand for, and price of, Ternium’s products and, accordingly, Ternium may not be able to increase or maintain its levels of sales volumes or prices.

8

Intense competition could cause Ternium to lose its share in certain markets and adversely affect its revenues.

The market for Ternium’s steel products is highly competitive, particularly with respect to price, quality and service. In both global and regional markets, Ternium competes against other global and local producers of steel products, which in some cases have greater financial and operating resources, or direct and indirect governmental support. Competition could result in declining margins and reductions in shipments. Ternium’s competitors could use their resources in a variety of ways that may affect Ternium negatively, including by making additional acquisitions, implementing modernization programs, expanding their production capacity, investing more aggressively in product development, and displacing demand for Ternium’s products in certain markets. To the extent that these producers become more efficient, Ternium could confront stronger competition and could fail to preserve its current share of the relevant geographic or product markets. In addition, there has been a trend in the past toward steel industry consolidation among Ternium’s competitors, and current competitors in the steel market could become larger competitors in the future. For further information on Ternium's competitors and their investments, see Item 4. “Information on the Company—B. Business Overview—Competition.”

Moreover, Ternium and other steel makers compete against suppliers of alternative materials, including aluminum, wood, concrete, plastic and ceramics. In particular, certain customers, such as the automotive industry, are increasing their consumption of lighter-weight materials, such as aluminum, composites and carbon fiber, sometimes as a result of regulatory requirements or government initiatives aimed at transitioning to a lower-carbon economy. Competition from these alternative materials could adversely affect the demand for, and consequently the market prices of, certain steel products and, accordingly, could affect Ternium’s sales volumes and revenues.

The recent Russia-Ukraine armed conflict and the consequent wave of international sanctions against Russia are expected to reduce the supply of steelmaking raw materials and steel products in the international markets, including slabs, pulverized coal for injection, and certain metals and ferroalloys.

On February 24, 2022, Russia launched a military attack on Ukraine. In response, the United States, the United Kingdom, and the European Union, among other countries, have imposed a wave of sanctions against certain Russian institutions, companies and citizens. As a result of the armed conflict and related sanctions, energy prices have spiked and foreign trade transactions involving Russian and Ukrainian counterparties have been severely affected.

Russia has a significant participation in the international trade of steel slabs, iron ore pellets, metallurgical coal, pulverized coal for injection, which are relevant inputs for Ternium’s operations. In addition, Ukraine has a relevant participation in the international trade of steel slabs and iron ore pellets. The availability and pricing of these inputs in the international markets are expected to be volatile and could result in limitations to Ternium’s production levels and higher costs, affecting our profitability and results of operations. As a result of the economic sanctions imposed on Russia, we or our contractors (including shipping companies) may not be able to continue purchasing or transporting products from, or making payments to, Ukrainian or Russian suppliers or counterparties; and we may not be able to promptly procure such raw materials from other suppliers, or we may be required to purchase raw materials at increased prices. For further information related to effects of shortages or disruptions in supplies for Ternium’s operations, see Risk Factors “Risks Relating to the Steel Industry - Price fluctuations, shortages or disruptions in the supply of raw materials, slabs, energy and other inputs could adversely affect Ternium’s profitability” and “Risks Relating to the Steel Industry - Ternium depends on a limited number of key suppliers”.

Price fluctuations, shortages or disruptions in the supply of raw materials, slabs, energy and other inputs could adversely affect Ternium’s profitability.

The manufacture of steel-related products requires substantial amounts of steelmaking raw materials, slabs, energy and other inputs from domestic and foreign suppliers. In particular, the Ternium companies consume large quantities of iron ore, metallurgical coal, pulverized coal for injection, scrap, ferroalloys, slabs, natural gas, electricity, oxygen and other gases in operating their blast and electric arc furnaces, as well as its downstream facilities. The availability and pricing of a significant portion of the raw materials, slabs, energy and other inputs used in Ternium’s operations are subject to market conditions, which can be volatile, government regulations or intervention, including import controls, allocation by suppliers, interruptions in production, or other events that can affect continuity of supply and prices, including wars, natural disasters, chronic climate changes, accidents and public health epidemics.

For example, extreme weather conditions in the southern United States and northern Mexico disrupted the stable provision of natural gas and energy in these markets, negatively affecting production in the first quarter of 2021. Furthermore, strong demand from Chinese steel producers coupled with certain supply restrictions imposed in connection with the COVID-19 pandemic, among other factors, contributed to a surge in international markets’ iron

9

ore prices during the first half of 2021 and metallurgical coal prices during the second half of 2021. In Argentina, shortages of natural gas in the past resulted in supply restrictions that, if repeated in the future, could lead to higher costs of production or production cutbacks at Ternium’s facilities in the country.

In the past, Ternium has usually been able to procure sufficient supplies of raw materials, energy and other inputs to meet its production needs; however, it could be unable to procure adequate supplies in the future. Any protracted interruption, discontinuation or other disruption of the supply of principal inputs to the Ternium companies (including as a result of strikes, lockouts, sanctions and other trade restrictions, accidents or natural disasters, armed conflicts, worldwide price fluctuations, the availability and cost of transportation, global epidemics such as COVID-19 pandemic or other factors) would result in lost sales and would have a material adverse effect on Ternium’s business and results of operations. For further information related to effects of global events see Item 3. Risk Factors “Risks Relating to the Steel Industry - A downturn in global or regional economic activity would cause a reduction in worldwide or regional demand for steel and would have a material adverse effect on the steel industry and Ternium”. For further information related to raw materials, energy and other inputs requirements see Item 4. “Information on the Company—B. Business Overview—Raw Materials, Slabs, Energy and Other Inputs” and “The recent Russian-Ukraine armed conflict and the consequent wave of international sanctions against Russia are expected to reduce the supply of steelmaking raw materials and steel products in the international markets, including slabs, pulverized coal for injection, and certain metals and ferroalloys.”

Ternium depends on a limited number of key suppliers.

Ternium depends on a limited number of key suppliers for the provision of some of its principal inputs, including Vale, a Brazilian company, for iron ore and KRU Overseas Limited, a Russian company, for pulverized coal for injection. In general, there is a trend in the industry towards consolidation among suppliers of raw materials, slabs and other inputs. The Ternium companies have entered into long-term contracts for the supply of some (but not all) of their principal inputs and it is expected that such agreements will be maintained and, depending on the circumstances, renewed. However, if any key supplier fails to deliver or if existing contracts cannot be renewed in the future, the Ternium companies could face limited access to certain raw materials, slabs, energy or other inputs, or could be subject to higher costs and delays resulting from the need to obtain their input requirements from other suppliers.

Risks Relating To Ternium's Business

If Ternium does not successfully implement its business strategy, its opportunities for growth and its competitive position could be adversely affected.

Ternium plans to continue implementing its business strategy, entailing a focus on sophisticated steel products, the pursuit of strategic growth opportunities and an enhancement of its competitiveness through a full product range offering, operational excellence, differentiated services with a strong distribution network and the attraction and training of talented employees. Any of these components or Ternium’s business strategy could be delayed or abandoned or could cost more than anticipated, any of which could impact its competitive position and reduce its revenue and profitability. For example, Ternium could fail to develop its projects and/or to make acquisitions and/or integrate newly acquired businesses to increase its steel production capacity; or may lose market share in its regional markets. Even if Ternium successfully implements its business strategy or achieves its medium and long-term goals, such strategy or goals may not yield the desired results. For information on Ternium’s business strategy, see Item 4. “Information on the Company—B. Business Overview—Our Business Strategy".

Future acquisitions or other significant investments could have an adverse impact on Ternium’s operations or profits, and Ternium may not realize the benefits it expects from these business decisions.

A key element of Ternium’s business strategy is to identify and pursue growth-enhancing opportunities. As part of that strategy, Ternium regularly considers acquisitions, greenfield and brownfield projects and other significant investments. However, any growth project will depend on market and financing conditions. Ternium must necessarily base any assessment of potential acquisitions or other investments on assumptions with respect to operations, profitability and other matters that may subsequently prove to be incorrect. Furthermore, Ternium may fail to find suitable acquisition targets or fail to consummate its acquisitions under favorable conditions. Ternium grew through several acquisitions, particularly in Mexico. In 2010 Ternium formed, together with Nippon Steel Corporation, or NSC, Tenigal, a company that manufactures and sells hot-dip galvanized and galvannealed steel sheets for the Mexican automotive market; in 2012, Ternium acquired a participation in the control group of Usiminas, the largest flat steel producer in Brazil; in 2014 and 2016, Ternium significantly increased its equity investment in Usiminas; and in 2017, Ternium acquired Ternium Brasil, a Brazilian steel slab producer.

10

Ternium’s acquisitions or other investments may not perform in accordance with its expectations and could have an adverse impact on its operations and profits. Furthermore, Ternium may be unable to successfully integrate any acquired businesses into its operations, realize expected synergies or accomplish the business objectives that were foreseen at the time of deciding any such investment. Moreover, Ternium may also acquire, as part of future acquisitions, assets unrelated to its business, and it may not be able to integrate them or sell them under favorable terms and conditions. These risks, and the fact that the integration of any acquired businesses would require a significant amount of time and resources from Ternium’s management and employees, could have an adverse impact on Ternium’s ongoing business and a material adverse effect on its business, financial condition and results of operations.

Ternium may be required to record a significant charge to earnings if it must reassess its goodwill, other amortizable intangible assets, investments in non-consolidated companies, property, plant and equipment and other long-lived assets.

In accordance with IFRS, management must test for impairment all of Ternium’s assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets subject to testing include goodwill, intangible assets, investments in non-consolidated companies, property, plant and equipment and other long-lived assets. In addition, management must test for impairment goodwill at least once a year, whether or not there are indicators of impairment. IFRS requires Ternium to recognize a non-cash charge in an amount equal to any impairment.

The Company reviews periodically the recoverability of its investments. As of December 31, 2021, goodwill in connection with the Company’s Mexican subsidiaries amounted to $662.3 million and the carrying value of the Company’s investment in non-consolidated companies, mainly related to its investment in Usiminas, amounted to $751.5 million. If Ternium’s management determines in the future that the goodwill from its acquisitions, its investments in non-consolidated companies or the carrying value of its property, plant and equipment and other long-lived assets are impaired, Ternium will be required to recognize a non-cash charge against earnings, which could materially adversely affect Ternium’s results of operations and net worth. For example, as of December 31, 2012, September 30, 2014, and December 31, 2015, Ternium wrote down its investment in Usiminas by $275.3 million, $739.8 million and $191.9 million, respectively. As of December 31, 2021, the carrying value of Ternium’s investment in Usiminas was $681.7 million and Ternium’s ownership stake had a market value of approximately $653.9 million. Any further write-downs to Ternium’s assets could have a material adverse effect on Ternium’s results of operations or net worth.

Failure to successfully implement Usiminas’ business strategy could have a material adverse effect on Ternium’s results, financial condition or net worth.

Since 2012, Ternium is a member of the control group of Usiminas, the largest flat steel producer in Brazil. In 2014, a conflict arose within the Usiminas control group and its board with respect to the governance of Usiminas, including with respect to the rules applicable to the appointment of senior managers, the application of the shareholders’ agreement in matters involving fiduciary duties, and the company’s strategy. Such conflict was resolved in 2018 by an agreement between Ternium, NSC and Usiminas’ employee pension fund (Previdência Usiminas), providing for new governance rules for Usiminas. Under the new Usiminas shareholders’ agreement (“New SHA”), no control group member can, without the consent of other shareholder group or groups, implement any change to Usiminas’ strategy or business practices.

The agreed-upon corporate governance rules for Usiminas include, among others, an alternation mechanism for the nomination of each of the chief executive officer and the chairman of the board of directors, as well as a mechanism for the nomination of other members of Usiminas’ executive board. The right to nominate Usiminas’ chief executive officer and chairman alternates between Ternium and NSC at every 4-year interval, comprising two consecutive 2-year terms. The executive board is composed of six members, including the chief executive officer and five vice-presidents, with Ternium and NSC nominating three members each.

In addition, the New SHA incorporates an exit mechanism consisting of a buy-and-sell procedure, exercisable at any time during the term of the New SHA after November 16, 2022. Such exit mechanism shall apply with respect to shares held by the NSC Group and by the group comprising Ternium’s subsidiaries and Tenaris’s Brazilian subsidiary, Confab Industrial S.A, and would allow either Ternium or NSC to purchase all or a majority of the Usiminas shares held by the other shareholder group.

11

If the parties fail to reach consensus, or if a new shareholder conflict were to emerge, Usiminas may not be successful at implementing the measures required to achieve sustainable profitability and, accordingly, Usiminas’ performance could be adversely affected and result in a material adverse effect on Ternium’s results, financial condition or net worth. For further information related to the conflict within the Usiminas control group and the agreement between Ternium, NSC and Previdencia Usiminas on governance rules for Usiminas, see Item 4. “Information on the Company—C. Organizational Structure—Other Investments—Usiminas”.

.

If Ternium does not comply with laws and regulations designed to combat governmental corruption in countries in which it sells its products, Ternium could become subject to fines, penalties or other sanctions and its sales and profitability could suffer.

Ternium conducts business in certain countries known to experience governmental corruption. Although Ternium is committed to conducting business in a legal and ethical manner in compliance with local and international statutory requirements and standards applicable to its business, there is a risk that employees or representatives may take actions that violate applicable laws and regulations that generally prohibit the making of improper payments to foreign government officials for the purpose of obtaining or keeping business, including laws relating to the 1997 OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions such as the U.S. Foreign Corrupt Practices Act and other anti-corruption laws adopted by the main countries in which Ternium operates (including Mexico, Brazil, Argentina and Colombia), which impose strict criminal liability on companies for corrupt practices undertaken by their employees or representatives.

Labor disputes at Ternium’s operating subsidiaries could result in work stoppages and disruptions to Ternium’s operations.

A substantial majority of Ternium’s employees at its manufacturing subsidiaries are represented by labor unions and are covered by collective bargaining or similar agreements, which are subject to periodic renegotiation. Strikes or work stoppages could occur prior to or during the negotiations leading to new collective bargaining agreements, during wage and benefits negotiations or, occasionally, during other periods for other reasons. Ternium could also suffer plant stoppages or strikes if it were to implement cost reduction plans. From time to time, Ternium takes measures to increase competitiveness; none of the measures taken in the past have resulted in significant labor unrest. However, Ternium cannot assure that this situation will remain stable or that future measures will not result in labor actions against Ternium companies. Any future stoppage, strike, disruption of operations or new collective bargaining agreements could result in lost sales and could increase Ternium’s costs, thereby affecting its results of operations. For further information on the geographic distribution of Ternium's workforce, see Item 6. “Directors, Senior Management and Employees—D. Employees”.

Changes in exchange rates or any limitation in the ability of the Ternium companies to hedge against exchange rate fluctuations could adversely affect Ternium’s business and results.

The operations of the Ternium companies expose them to the effects of changes in foreign currency exchange rates and changes in foreign exchange regulations. A significant portion of Ternium’s transactions is carried out in currencies other than the U.S. dollar. As a result of this foreign currency exposure, exchange rate fluctuations impact the Ternium companies’ results and net worth as reported in their income statements, statements of comprehensive income and statements of financial position in the form of both translation risk and transaction risk. In the ordinary course of business, the Ternium companies may see fit to enter into exchange rate derivatives agreements to manage their exposure to exchange rate changes. Future regulatory or financial restrictions in the countries where Ternium operates may reduce its ability to manage its exposure to exchange rate fluctuations, and thus could cause an adverse impact on Ternium’s results of operations, financial condition or cash flows. For information concerning the effect of the changes in exchange rates on Ternium’s business and results, see Item 5. “Operating and Financial Review and Prospects—Overview”.

Cyberattacks could have a material adverse impact on Ternium's business and results of operation.

Ternium relies heavily on information systems to conduct its operations; and digital technologies have an increasingly significant role across our business. Although Ternium devotes significant resources to protect its systems and data, and it continually monitors external developments and available information on threats and security incidents, it has experienced and will continue to experience varying degrees of cyber incidents in the normal conduct of its business, which may occasionally include sophisticated cybersecurity threats such as unauthorized access to data and systems, loss or destruction of data, computer viruses or other malicious code, phishing, spoofing and/or cyberattacks. These

12

threats often arise from numerous sources, not all of which are within Ternium's control, such as fraud or malice from third parties, including fraud involving business email, failures of computer servers or other accidental technological failure, electrical or telecommunication outages or other damage to its property or assets. Cyber-attack attempts, such as ransomware, phishing, spoofing and whaling, continued to increase throughout 2021 in the context of the COVID-19 pandemic, due to a significant expansion of remote work practices among Ternium’s employees, its customers and suppliers and the increasing digitalization of work. For example, in 2021, Ternium suffered 367 cyber-security attacks mainly consisting of phishing attacks; none of these attacks led to known breaches of Ternium’s business-critical IT systems and, as such, did not result in any material business impact. In response to the increase in the number and sophistication of ransomware attacks, U.S. and EU regulatory agencies have implemented regulations to prevent victims from making ransomware payments and to deter third parties from facilitating or processing such payments to cyber actors. In this context, Ternium enhanced cybersecurity controls and implemented comprehensive processes and procedures to monitor, detect and respond to hacking, malware infection, cybersecurity compromise and other risks. In addition, Ternium has launched awareness and ethical phishing campaigns aimed at protecting it against cyber-threats and it regularly trains its executives and employees to identify and report cybersecurity incidents.

Given the rapidly evolving nature of cyber threats, there can be no assurance that the systems that Ternium has designed to prevent or limit the effects of cyber incidents or attacks and the mitigation actions adopted in connection with such attacks will be sufficient to prevent or detect such incidents or attacks, or to avoid a material adverse impact on its systems when such incidents or attacks do occur. If Ternium’s systems for protecting against cybersecurity risks are circumvented or breached, this could also result in disruptions to its business operations (including but not limited to, defective products, production downtimes or loss of productivity), access to financial reporting systems, the loss of access to critical data or systems, misuse or corruption of critical data and proprietary information (including intellectual property and customer data), as well as damage to Ternium’s reputation with its customers and the market, failure to meet customer requirements, customer dissatisfaction and/or regulatory fines and penalties (including for inadequate protection of persona data and/or failure to notify the competent authorities for such breach) or other financial costs and losses. In addition, given that cybersecurity threats continue to evolve, Ternium will be required to devote additional resources in the future to enhance its protective measures or to investigate and/or remediate any cybersecurity vulnerabilities. Although Ternium has considered contract insurance coverage options for cyber risks, it does not currently maintain cybersecurity insurance, and the insurance it carries for property damage and general liability may not be adequate or available to protect it from damages derived from cyber events, or coverage may be limited. Moreover, any investigation of a cyberattack would take time before completion, during which Ternium would not necessarily know the extent of the actual or potential harm or how best to remediate it, and certain errors or actions could be repeated or compounded before duly discovered and remediated (all or any of which could further increase the costs and consequences arising out of any cyberattack).

The physical risks resulting from climate change, including extreme weather conditions and shifts in weather patterns may adversely impact Ternium’s business.

Ternium’s business has been, and in the future could be, affected by severe weather in areas where it operates, which could materially affect its operations and financial results. Extreme weather events and natural disasters, such as hurricanes, cyclones, droughts, floods and fires could affect businesses’ operations, workforce, markets, infrastructure, raw materials and assets. For example, in 2020 and in 2021, iron ore supplies to our operations in Argentina from Brazil's iron ore mines in the Pantanal Region (Mato Grosso do Sul state), which are barged down the Paraguay and Paraná rivers, were disrupted as this waterway recorded very low stages, forcing Ternium Argentina to procure iron ore from alternative sources at higher costs. In addition, during the first quarter of 2021, the provision of natural gas and energy to our operations in Mexico were disrupted by extreme weather conditions in the southern United States and northern Mexico, negatively affecting steel production in the first quarter of 2021.

The communities surrounding our main production sites in Argentina, Brazil and Mexico are vulnerable to flooding due to extreme weather events. In recent years, our operation in Brazil and certain of our operations in Argentina experienced intense rainfall affecting personnel’s access to Ternium’s facilities. In addition, as Ternium’s steel shops in Mexico are located at water stressed areas, its operations could be subject to water shortages and/or increased water costs, in case of severe draughts.

Chronic climate changes, such as changes in precipitation patterns and rising of mean temperatures and sea levels may result in increased operating costs or capital expenditures, due to supply shortages or damage to facilities, personnel evacuation, increased insurance premiums or reduced availability of insurance, decreases in revenue derived from lower sales, disruption of operations or lower production levels, negative impact on workforce and write-offs and/or early retirement of assets, all of which could adversely affect Ternium’s financial condition, results of operations and cash flows.

Risks Relating To Ternium's Mining Activities

Ternium has equity interests in two iron ore mining companies in Mexico: a 100% interest in Las Encinas and a 50% interest in Consorcio Peña Colorada. Ternium's mining activities are subject to the following risks:

Operational accidents and unexpected natural catastrophes may damage the environment, destroy properties and affect production or cause injuries and death, which would adversely impact Ternium's operations and profitability, and result in material liabilities.

Ternium carries out extractive, processing and logistical operations in many geographic locations. Liabilities associated with Ternium’s mining activities include those resulting from tailings and sludge disposal, effluent management, iron ore pulp and fines transportation, and rehabilitation of land disturbed during the mining processes. Ternium’s operations involve the use, handling, storage, discharge and disposal of hazardous substances and the use of natural resources. The iron ore mining industry is generally subject to significant risks and hazards, including environmental pollution, such as spilling or emissions of polluting substances or other hazardous materials; operational incidents, such as open-cut pit wall failures, rock falls, tailings dam breaches or incidents from the storage, transportation or use of explosives; transportation incidents, involving mobile equipment or machinery, slurry pipes and cable transportation; and may also be subject to unexpected natural catastrophes. This could result in environmental damage, damage to or destruction of properties and facilities, personal injury or death, and delays in production. For example, in January 2019, a tailings dam at Vale’s Córrego do Feijão mine in Brumadinho, Brazil, collapsed, releasing a mudflow that resulted in hundreds of people dead or missing. Ternium operates mines with tailings dams in Mexico and could become subject to liabilities arising from similar incidents in the future. Over time, Ternium has conducted stability studies of its tailings dams, with the help of consultant companies, using increasingly strict standards for seismic areas and, as a result, has been carrying out several investment projects to reinforce certain dams and has to carry out several more, some of which are in the process of obtaining approval from environmental authorities. Although Ternium believes that, once completed, ongoing and planned investment projects will further mitigate the risk of incidents, it cannot guarantee that failures or breaches will not occur prior to or after the completion of reinforcement works. For further information, see Item 4. “Information on the Company - B. Business Overview - Mining”.

Ternium may also be subject to claims under federal and local laws and regulations for toxic torts, natural resource damages and other damages, as well as for the investigation and clean-up of soil, surface water, sediments, groundwater and other natural resources. Claims for damages and reclamation may arise out of current or former conditions at sites that Ternium owns, leases or operates or at inactive sites that Ternium currently owns, leased-land sites and third-party waste disposal sites. Ternium may be held responsible for other sites in the future. Ternium also could be subject to litigation for alleged bodily injuries arising from claimed exposure to hazardous substances allegedly used, released, or disposed of by Ternium. Environmental damages caused by Ternium’s operations may result in costs and liabilities that could materially and adversely affect margins, cash flow and profitability. Third-party claims based on environmental or physical damages may exceed the limit of liability of the insurance policies we could have in place.

Required governmental concessions could be subject to prior consultation with native communities, changes or termination, permits and rights of use and occupancy could be difficult to obtain or maintain and taxes or royalties applicable to the mining industry could increase, all of which could adversely affect Ternium's mining activities and operating costs.

Ternium’s mining activities are subject to specific regulations and depend on concessions and authorizations granted by governmental authorities. Increased government intervention or amendments to applicable laws and regulations as well as claims or legal actions from native or local communities or other third parties in Mexico, may alter the terms pursuant to which Ternium is required to pursue exploration, mining and ore processing activities. Selected mining technologies, new taxes and/or royalties may be imposed on mining activities, leading to unexpected capital expenditures and higher costs. For further information on regulatory risks in Mexico, see Risk Factors “Risks Relating to the Countries in Which Ternium Operates - Mexico: Regulatory changes in Mexico could adversely impact Ternium's results of operations and net results.”

Iron ore exploration and exploitation concessions as well as water concessions may be revoked if the competent government authorities determine that Ternium does not comply with its obligations under the respective concession terms and agreements. Furthermore, in order to explore or exploit mines, it is necessary to obtain the right of use and occupancy of the land where the mines are situated. Even though government regulations frequently establish provisions intended to facilitate the establishment of such rights, in some cases it may be difficult to reach and

14

maintain agreements with the native or local communities or landowners, or such agreements may be excessively onerous. If Ternium is unable to establish use and occupancy rights on acceptable terms, its mining activities may be compromised. In addition, Ternium’s iron ore mining subsidiaries need to obtain, in the normal course of business, permits for the preparation of new iron ore bodies at the mines and for the expansion of tailings deposit capacity. If Ternium is unable to obtain such permits on a timely basis, it may need to alter its mining and/or production plans, which could lead to unexpected capital expenditures and higher costs.

Ternium's reserve estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves uneconomical to mine in the future or cause Ternium to revise its reserve estimates.

Ternium’s reserves are estimated quantities of ore that it has determined can be economically mined and processed under present and anticipated conditions to extract their mineral content. There are numerous uncertainties inherent in estimating quantities of reserves and in projecting potential future rates of mineral production, including factors beyond Ternium's control. Reserve calculations involve estimating deposits of minerals that cannot be measured in an exact manner, and the accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgment. Reserve estimates also depend on assumptions relating to the economic viability of extraction, which are established through the application of a life of mine plan for each operation or project providing a positive net present value on a forward-looking basis, using forecasts of operating and capital costs based on historical performance, with forward adjustments based on planned process improvements, changes in production volumes and in fixed and variable proportions of costs, and forecasted fluctuations in costs of raw material, supplies, energy and wages. These forecasts and projections involve assumptions and estimations that, although Ternium believes are reasonable at the time of estimating its reserves, may change in the future and may fail to anticipate geological, environmental or other factors or events that could make it difficult or unprofitable to mine certain ore deposits.

In addition, Ternium’s reserve estimates are of in-place material after adjustments for mining depletion and mining losses and recoveries, with no adjustments made for metal losses due to processing. As a result, no assurance can be given that the indicated amount of ore will be recovered from Ternium’s reserves, or that it will be recovered at the anticipated rates, or that extracted ore will be converted into saleable production over the mine life at levels consistent with its reserve estimates. Reserve estimates may vary from those included in this annual report, and results of mining and production subsequent to the date of an estimate may lead to future revisions of estimates. Estimates of mine life may require revisions based on actual production figures, changes in reserve estimates and other factors. For example, fluctuations in the market prices of minerals, reduced recovery rates or increased operating and capital costs due to inflation, exchange rates, mining duties or other factors could affect Ternium’s mine life projections. To the extent that market price fluctuations or changes in its operating and capital costs increase its costs to explore, locate, extract and process iron ore, Ternium may be required to lower its reserve estimates if certain ore reserves become uneconomical to mine in the future.

Ternium's exploration activities are subject to uncertainties as to the results of such exploration; even if the exploration activities lead to the discovery of ore deposits, the effective exploitation of such deposits remains subject to several risks.

Exploration activities are highly speculative, involve substantial risks and may be unproductive. Ternium may incur substantial costs for exploration which do not yield the expected results. The failure to find sufficient and adequate reserves could adversely affect Ternium’s business. In addition, even if ore deposits are discovered, the ability to pursue exploitation activities may be delayed for a long time during which market conditions may vary. Significant resources and time need to be invested in order to establish ore resources through exploration, define the appropriate processes that shall be undertaken, obtain environmental licenses, concessions and permits (including water usage permits), acquire land, build the necessary facilities and infrastructure for greenfield projects and obtain the ore or extract the metals from the ore. If a project does not turn out to be economically feasible by the time Ternium is able to exploit it, Ternium may incur substantial write-offs.

Inability to complete investment projects required to maintain iron ore and pellets production rates over time could increase Ternium’s steel production costs.

Mining requires continuous investment to sustain production rates. Such investments require, among other things, the design of the project, the awarding of environmental permits and the successful execution of civil works. If Ternium fails to timely carry out the investment projects required to maintain iron ore and pellets production rates over time,

15

including tailing dams, Ternium could have to substitute internally produced iron ore with third party purchases, with a consequent increase in steel production costs.

Ternium's expected costs and capital expenditure requirements for exploration, exploitation or restoration activities may vary significantly and affect its financial condition and expected results of operations.

Ternium may be subject to increased costs or delays relating to the acquisition of adequate equipment for the exploration and exploitation of ore deposits, or restoration of exhausted mines. Moreover, Ternium may face increasing costs or capital expenditure requirements related to several factors, including changes in environmental regulations, diminished iron ore reserve grades, deeper pits and operational sections of its mines, iron ore deposits within the pit area that are more difficult to locate or extract, additional maintenance works in dams and ponds, and increased energy supply requirements that may be difficult to obtain. Adverse mining conditions and other situations related to the operation of the mine and related facilities during their life cycle, whether permanent or temporary, may lead to a significant increase in projected capital expenditures and costs, as well as affect Ternium’s ability to produce the expected quantities of mineral. If this occurs, Ternium’s financial condition and expected results of operations may also be negatively affected.

Difficulties in relationships with local communities may adversely affect Ternium’s mining activities and results of operations.

Communities or individuals living or owning land near areas where Ternium operates may take actions to oppose and interfere with its mining activities. Even if a community has an agreement in place with Ternium, internal disputes within that community could result in blockades to disrupt Ternium operations or iron ore transportation, or legal proceedings to suspend mining activity. Although Ternium makes significant efforts to maintain good relationships with such communities, actions taken by them (or by interest groups within those communities), including requesting the government to revoke or cancel Ternium’s concessions or environmental or other permits, may hamper Ternium’s ability to conduct its mining activities as planned, prevent Ternium from fulfilling agreements reached with the government, or significantly increase the cost of exploring and/or exploiting the mines, thereby adversely affecting Ternium’s business and results of operations.

In the past, Ternium faced actions by certain native or local Mexican communities demanding higher compensation or other benefits, or seeking to stop Ternium’s activities. Although attempted legal actions against Ternium did not succeed, Mexican legislation affords judges the power to preemptively suspend environmental or other permits or concessions and take certain other measures to protect the “ejidos” (land jointly owned by native communities) until the claim is resolved. An adverse legal decision suspending or cancelling permits, or the illegal occupation of facilities, could adversely impact Ternium’s mining activities and results of operations.

Risks Relating To The Structure Of The Company

The Company’s dividend payments depend on the results of operations and financial condition of its subsidiaries and could be affected by legal, contractual or other limitations or tax changes.

The Company is a holding company and conducts all its operations through subsidiaries. Dividends or other intercompany transfers of funds from those subsidiaries are the Company’s primary source of funds to pay its expenses, debt service and dividends and to repurchase shares or ADSs.

The ability of the Company’s subsidiaries to pay dividends and make other payments to us will depend on their results of operations and financial condition and could be restricted by applicable corporate and other laws and regulations, including those imposing foreign exchange controls or restrictions on the transfer of money to foreign accounts or the payment of dividends, and agreements and commitments of such subsidiaries. If earnings and cash flows of the Company’s operating subsidiaries are substantially reduced, the Company may not be in a position to meet its operational needs or to pay dividends. For information on exchange controls imposed in Argentina, see “—Risks Relating to the Countries in Which Ternium Operates - Argentina: Argentine exchange controls could negatively impact Ternium Argentina’s operations, or prevent it from paying dividends or transferring cash surpluses abroad, as a result of its inability to access the foreign exchange market."; and note 30 “Foreign exchange restrictions in Argentina” of Ternium’s audited consolidated financial statements included in this annual report.

The Company’s ability to pay dividends to shareholders is subject to legal and other requirements and restrictions in effect at the holding company level. For example, the Company may only pay dividends out of net profits, retained

16

earnings and distributable reserves and premiums, each as defined and calculated in accordance with Luxembourg law and regulations. In addition, the Company’s dividend distributions (which are currently imputed to a special tax reserve and are therefore not subject to Luxembourg withholding tax) may be subject to Luxembourg withholding tax if current Luxembourg tax law were to change.

The Company’s controlling shareholder may be able to take actions that do not reflect the will or best interests of other shareholders.

As of the date of this annual report, San Faustin beneficially owned 65.03% of the Company's shares and Tenaris, which is also controlled by San Faustin, held 11.46% of the Company’s shares. Rocca & Partners Stichting Administratiekantoor Aandelen San Faustin, (“RP STAK”), holds voting rights in San Faustin sufficient in number to control San Faustin. As a result, RP STAK is indirectly able to elect a substantial majority of the members of the Company’s board of directors and has the power to determine the outcome of most actions requiring shareholder approval, including, subject to the requirements of Luxembourg law, the payment of dividends. The decisions of the controlling shareholder may not reflect the will or best interest of other shareholders. In addition, the Company’s articles of association permit the Company’s board of directors to waive, limit or suppress preemptive rights in certain cases. Accordingly, the Company’s controlling shareholder may cause its board of directors to approve in certain cases an issuance of shares for consideration without preemptive rights, thereby diluting the minority interest in the Company. See “Risks Relating to the Company's ADSs – Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain cases”.

Non-controlling interests in the Company's subsidiaries could delay or prevent us from completing our strategy.

The Company does not own 100% of the interests in certain of the Company’s subsidiaries. As of February 28, 2022, 26.03% of Ternium Argentina was held by Administración Nacional de la Seguridad Social, or ANSeS, Argentina’s governmental social security agency, and 11.48% was publicly held. In addition, Ternium holds a 51% ownership interest in Tenigal (NSC holds the remaining 49%); and a 48% equity interest in Techgen S.A. de C.V. (“Techgen”). Ternium also has a participation in the control group of Usiminas. For further information on the Usiminas investment, see Item 4. “Information on the Company—C. Organizational Structure—Other Investments—Usiminas”. The existence of non-controlling interests in these companies could prevent Ternium from taking actions that, while beneficial to Ternium, might not be beneficial to each relevant subsidiary, considered separately. As a result, the Company could be delayed or prevented from completing its strategy or fully maximizing Ternium’s competitive strengths.

Risks Relating To The Countries In Which Ternium Operates

Negative economic, political, social and regulatory developments in certain markets where Ternium has a significant portion of its operations and assets could hurt Ternium’s shipment volumes or prices, increase its costs or disrupt its manufacturing operations, thereby adversely affecting its results of operations and financial condition.

The results of Ternium’s operations are subject to the risks of doing business in emerging markets, principally in Mexico, Brazil and Argentina and, to a lesser extent, in Colombia, and have been, and could in the future be, affected from time to time to varying degrees by economic, political, social, and regulatory developments, such as nationalization, expropriation or forced divestiture of assets; restrictions on production, domestic sales, imports and exports; travel or trade bans; interruptions in the supply of essential energy inputs; restrictions on the exchange or transfer of currency; inability or increasing difficulties to repatriate income or capital or to make contract payments; inflation; devaluation; or other events, including wars and other international conflicts, natural disasters, chronic climate changes and public health epidemics (such as COVID-19); civil unrest and local security concerns that threaten the safe operation of its facilities and operations; direct and indirect price controls; tax increases and changes (including retroactive) in the interpretation, application or enforcement of tax laws and other claims or challenges; cancellation of contract rights; and delays or denial of governmental approvals. Both the likelihood of such occurrences and their overall effect upon Ternium vary greatly from country to country and are not predictable. Realization of these risks could have an adverse impact on the results of operations and financial condition of Ternium’s subsidiaries located in the affected country and, depending on their materiality, on the results of operations and financial condition of Ternium as a whole.

Mexico

17

Ternium has significant manufacturing operations and assets located in Mexico and a majority of its sales are made to customers in this country. The majority of Ternium’s revenues are derived from its Mexican operations and, therefore, are related to market conditions in Mexico and to changes in its economic activity. Ternium’s business could be materially and adversely affected by economic, political and regulatory developments in Mexico.

Political, economic and social conditions and government policies in Mexico could negatively impact Ternium’s business and results of operations.

In the past, Mexico has experienced several periods of slow or negative economic growth, high inflation, high interest rates, currency devaluation and other economic problems. Furthermore, the Mexican national economy tends to reflect changes in the economic environment in the United States and could be affected by changes in the terms of trade. In addition, actions and policies that could be adopted by the Mexican federal government concerning the economy could have a significant impact on market conditions affecting Ternium’s operations in Mexico. If problems such as deterioration in Mexico’s economic conditions re-emerge (for example, as a result of lower revenues due to a decline in the price of oil) or there is a future re-emergence of social instability, political unrest, reduction in government spending, increased government intervention or other adverse social or political developments, foreign exchange and financial markets may exhibit continued volatility, which, depending on its severity and duration, could adversely affect the business, results of operations, financial condition or liquidity of Ternium. Moreover, adverse economic conditions in Mexico could result in, among other things, higher interest rates coupled with reduced opportunities for refunding or refinancing, reduced domestic consumption of Ternium’s products, decreased operating results and delays in the completion of ongoing and future capital expenditures.

A Mexican energy reform could adversely impact Ternium’s results of operations and net results.

In March 2021, the Mexican Congress approved a significant reform to the energy market in Mexico. Among other changes, the new Energy Industry Law (“LIE”) grants priority to Mexico’s state-owned electric power generation and distribution company (“CFE”) over private generators in the supply of electric power to the Mexican market and mandates a revision of power generation and transaction agreements between CFE and independent electric power suppliers. In addition, the LIE eliminates mandatory power supply auctions for energy supplies requiring the use of CFE’s distribution network, relaxes the requirements for the granting of clean energy certificates in favor of CFE, and imposes serious restrictions on the renewable energy generation system through self-supply, widely used by private companies. The new LIE was challenged in court and its application is currently suspended. In September 2021, President Andrés Manuel López Obrador submitted to Congress a constitutional reform proposal of the electricity sector, which seeks to reverse the legal framework derived from the 2013 constitutional energy reform that opened the sector to private investment. The congressional debate on the reform started in January 2022 and two-thirds of the votes are required for approval. There is uncertainty about the approval of the constitutional reform and related amendments to the energy market regulation. Approval of proposed changes could negatively affect the operations of Techgen, where Ternium holds a 48% equity interest and which supplies electricity for most of our Mexican operations. At this stage, we cannot fully assess the effects of the energy market reform on Ternium’s operations and the Mexican economy in general and, consequently, on the results of operations and financial conditions of Ternium’s businesses in Mexico.

Violence and crime in Mexico could negatively impact Ternium’s business and operations.

In recent years, there has been a significant increase of violent crimes in Mexico, including the Monterrey area in Nuevo León, where Ternium’s main facilities are located, and Michoacán, where some of Ternium’s mining facilities are placed. Security issues could affect Ternium’s day-to-day operations and could also result in an economic slowdown, reducing domestic demand for its products and thereby having an adverse effect on Ternium’s business. A deterioration of the security situation could result in significant obstacles or additional costs to the implementation of growth plans in Mexico, including delays in the completion of capital expenditures.

Unexpected changes in trade rules with the United States could adversely impact Ternium’s results of operations and net results.

The United States-Mexico-Canada Agreement (“USMCA”) became effective in July 2020 replacing the North American Free Trade Agreement (NAFTA). In addition, during 2019 Mexico and the United States agreed to waive a 25% tariff on steel products exported to the United States (which had been imposed during 2018) subject to an agreed premise of continuous monitoring for surges in steel imports and transshipment of non-USMCA material into the

18

United States. Furthermore, in 2019 the United States, Mexico and Canada agreed to modify the definition of “North American steel” (with such amendment becoming effective in July 2027), for purposes of vehicles being awarded preferential treatment under USMCA, restricting the defined term to steel melted and poured within the three countries. Uncertainties about potential new trade conflicts could adversely affect the investment climate and economic activity in Mexico. Moreover, amendments to, or the termination of current terms of trade could adversely and materially affect Ternium’s shipments, results of operations and net worth.

Brazil

Ternium has significant manufacturing operations and assets located in Rio de Janeiro, Brazil, and some of its sales are made in Brazil. In addition, Ternium has a participation in Usiminas. Ternium Brasil’s and Usiminas’ profitability could be materially and adversely affected by economic, political, social, fiscal and regulatory developments in Brazil.

Changing economic policies and political conditions in Brazil, which on several occasions in the past resulted in economic uncertainties and recession, may occur in the future, thereby adversely affecting Ternium's business, financial condition and results.

The Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the course of the country’s economy. The Brazilian government’s actions to control inflation and implement other policies have involved hikes in interest rates, wage and price controls, foreign exchange controls and devaluation, freezing of bank accounts, capital controls and restrictions on imports. If repeated in the future, such governmental policies may adversely affect Ternium’s results of operations. The Brazilian government’s policies may also result in increases in tax payments or tariffs, which could adversely affect industry profitability. For example, the Brazilian congress is discussing major changes to the Brazilian tax regime, which, among other things, would replace current federal, state and municipal taxes levied on the trade of good and services with a single national value added tax. In addition, the Brazilian congress is discussing a tax reform proposal focused on income tax. Ternium cannot predict whether, if approved, the new tax regime would result in a net tax burden increase for its operations. Any increase in the applicable tax burden or tariffs could affect Ternium’s projected cash flow and profitability. The Brazilian economy has been affected by inflation, energy shortages, illiquid lending markets and other political, diplomatic, social and economic developments. Uncertainty over whether the Brazilian government will change policies or regulations affecting these or other factors may contribute to economic instability in Brazil. Ternium’s business and results of operations in Brazil could be adversely affected by rapidly changing economic conditions in Brazil or by the Brazilian government’s policy response to such conditions.

Political instability could adversely affect Ternium's business, financial condition and results.

Brazil’s political environment has historically influenced, and continues to influence, the performance of the country’s economy. Political crises have affected public and investor confidence, which resulted in economic deceleration. Brazil has experienced heightened economic and political instability derived from various investigations into allegations of money laundering and corruption being conducted by the Office of the Brazilian Federal Prosecutor, including the Lava Jato investigation, which has had a negative impact on the Brazilian economy and political environment and contributed to a decline in market confidence in Brazil. Ternium cannot predict whether a new political crisis will arise in the future nor its effect on the Brazilian economy and, consequently, on the results of operations and financial conditions of Ternium’s businesses in Brazil.

Inflation may undermine economic growth in Brazil and impact Ternium's costs, thereby adversely affecting its results of operations and financial position.

High levels of inflation have in the past undermined the Brazilian economy and the government’s ability to stimulate economic growth and if a similar situation happened again in the future, Ternium’s results of operations and financial position could be negatively impacted, as Ternium Brasil’s BRL-denominated costs (mainly labor-related costs) would increase, thereby affecting Ternium’s cost-competitiveness. Inflationary pressures may also lead to the imposition of additional government policies to combat inflation and hinder access to Brazilian capital markets, which could adversely affect Ternium’s business and ability to finance operations and capital expenditures, making it impossible to estimate with reasonable certainty Ternium Brasil’s future results of operations.

Argentina

19

A significant portion of Ternium’s sales are made in Argentina through its subsidiary, Ternium Argentina. Ternium Argentina’s business could be materially and adversely affected by economic, political, social, fiscal and regulatory developments in Argentina. For more information on Ternium’s sales in Argentina, see Item 4. “Information on the Company—B. Business Overview —Sales—Southern Region.”

Economic and political instability in Argentina, which on several occasions resulted in economic uncertainties and recession, may adversely affect Ternium’s business, financial condition and results.

Ternium’s business and results of operations in Argentina depend on local macroeconomic conditions, among other factors. Steel shipments to the Argentine domestic market were severely affected in different opportunities over the last decades. This happened with the 2008-2009 downturn in the global economy; in 2016, when the country faced a significant rebalancing of the economy’s relative prices; in 2018-2019 as the economy was affected by a severe downturn resulting from financial market volatility, high interest rates and heightened political uncertainty during the presidential election process; and, more recently, in 2020 as the economy was affected by the COVID-19 outbreak.

Over the past years, the Argentine economy and capital investment have been affected by, among other factors, political, economic and financial uncertainties as well as government intervention in, or limitations to, the conduct of business in the private sector and other government measures affecting investors’ confidence. The Argentine economy is currently facing significant challenges, including a slow recovery following the COVID-19 pandemic, high and unpredictable inflation rates and a high fiscal deficit in a highly indebted economy, which could affect macroeconomic conditions and economic growth, and cause a drop in demand for Ternium Argentina’s products in the domestic market.

In addition, Argentina has recently reached a final agreement with the International Monetary Fund (“IMF”) on a sovereign debt restructuring process, whose outcome is uncertain. In January 2022, the IMF and the Argentine authorities reached an understanding on key policies as part of their discussions of an IMF-supported program, and in March 2022 the Argentine Congress and the IMF's Executive Board approved the program. Failure to implement any approved program with the IMF could further adversely affect the country’s economy and lessened financial sources could impair Argentina’s ability to foster economic growth.

Ternium’s business and results of operations in Argentina could be adversely affected by rapidly changing economic conditions in Argentina or by the Argentine government’s policy response to such conditions.

Inflation may undermine economic growth in Argentina and impact Ternium’s costs, thereby adversely affecting its results of operations and financial position.

In the past, inflation has undermined the Argentine economy and the government’s ability to stimulate economic growth. Consumer price inflation in Argentina, as reported by INDEC, the Argentine statistics and census bureau, was 50.9% in 2021, 36.1% in 2020 and 53.8% in 2019. Sustained high inflation in Argentina negatively impacts Ternium’s results of operations and financial position, as ARS-denominated costs (mainly labor-related costs) at Ternium Argentina increase, thereby affecting cost-competitiveness and margins. A high inflation economy could undermine Argentina’s foreign competitiveness in international markets and negatively affect economic activity and employment levels. Argentine inflation rate volatility makes it impossible to estimate with reasonable certainty the extent to which activity levels and results of operations of Ternium Argentina could be affected in the future.

The Argentine government has increased taxes on Argentine companies and could further increase the tax burden in the future, which could adversely affect Ternium's results of operations, net results and financial condition.

The sustained and significant devaluation of the Argentine peso against the U.S. dollar coupled with high inflation rates over the last decade have resulted in a material reduction of the real value that Ternium Argentina can deduct as cost of sales or cost of financial investments for tax purposes, thus creating artificial gains that are subject to income tax. Inflation adjustment for tax purposes is limited and subject to significant restrictions. For example, inflation adjustment of inventories and other current assets is permitted only if the consumer price inflation rate surpasses 100% in a 36-month period up to the close of the relevant fiscal year. Until 2020, even if this threshold were to be achieved, only one-sixth (or 16.67%) of the effect of the inflation adjustment could be recorded in the relevant fiscal year, and the balance had to be recorded, in equal installments, over the next five fiscal years. Although such limitation is not applicable for fiscal year 2021 (due to national congress’ failure to approve the 2022 annual budget), it could be reinstated once the new budget is approved by congress or in any other tax law. Furthermore, because inflation

20

adjustment of cash positions generated during the current fiscal year is not permitted, high nominal interest rates, which are normally expected in high inflation scenarios, materially overstate the financial income of such cash positions for tax purposes.

In September 2018, the Argentine government suspended certain tax refunds and imposed a new tax that currently levies a 3% rate on exports of goods. Provincial and municipal taxes on Ternium Argentina’s operations have also increased over the last years. In December 2021, the federal government and a significant number of local governments reached a new tax consensus, which replaced the 2017 tax consensus that provided for a gradual decrease of tax burden on Argentine corporations over a five-year period. Ternium cannot predict whether the 2022 budget, or any new tax regime or future tax reform could result in an increase of the tax burden for its operations in Argentina. If the tax burden on Ternium Argentina or its shareholders further increases in the future, Ternium’s results of operations, net results and financial condition could be adversely affected.

Argentine exchange controls could negatively impact Ternium Argentina’s operations, or prevent it from paying dividends or transferring cash surpluses abroad, as a result of its inability to access the foreign exchange market.

In the past, the Argentine authorities took several measures to reduce volatility of the ARS/$ exchange rate and implemented formal and informal restrictions on capital inflows into Argentina and capital outflows from Argentina. Certain foreign exchange restrictions that had been gradually lifted in December 2015 were reinstated in 2019 and have continued to tighten over the past two years. The Argentine government tightened controls on the flows of capital by requiring Argentine companies to repatriate all export proceeds from sales of goods and services (including U.S. dollars received through advance payment and pre-financing facilities) and convert such proceeds into Argentine pesos, restricting the purchase of foreign currency for saving purposes, and limiting or conditioning the ability of Argentine companies to access the foreign exchange market.

As of December 31, 2021, Ternium Argentina’s cash and cash equivalents and other investments, held in Argentine financial institutions, amounted to $965 million. For a breakdown of Ternium Argentina’s cash and cash equivalents and other investments as of December 31, 2021, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report. Since 2019, access to the Argentine foreign exchange market for various purposes (including to repay foreign financial indebtedness, to pay services to related parties or to distribute dividends abroad) has been severely limited. Prior approval from the Argentine central bank, which is rarely (if ever) granted, is required to purchase foreign currency for payment of dividends to foreign shareholders and for other payments to affiliates abroad. Ternium Argentina has requested prior approval to the Argentine central bank for certain payment of services to affiliates abroad and, as of the date of this annual report, no such approvals have been granted.

Foreign exchange restrictions have also begun to affect imports of goods and services. Some of Ternium Argentina’s key steelmaking inputs, including iron ore and metallurgical coal, are imported into Argentina from other markets. In March 2022, the Argentine government imposed further restrictions to access the foreign exchange market for payment of imports. If such restrictions are maintained, or are further tightened, Ternium Argentina could be restricted from making payment of imports for key steelmaking inputs which would adversely affect its operations, or would need to resort to alternative, more expensive arrangements, which would affect its results of operations.

As an environment of volatility and uncertainty remains in place as of the date of this annual report, there is no assurance that the Argentine central bank or other Argentine authority will not further tighten exchange controls or impose new foreign exchange restrictions in the future. Any such additional controls and restrictions could further impair Ternium Argentina’s ability to access the official foreign exchange market, expose Ternium to losses resulting from fluctuations in the exchange rate, affect Ternium’s ability to finance its investments in Argentina and impair Ternium Argentina’s ability to make payments to foreign suppliers or creditors (which could disrupt Ternium Argentina’s operations), pay dividends or royalties abroad, or fund investments or other activities offshore. For more information on our foreign exchange restrictions in Argentina, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report.

Restrictions on supply of energy to Ternium Argentina’s operations could curtail its production and negatively impact Ternium’s results of operations.

In the past, Argentina has suffered from an insufficient level of investment in natural gas and electricity supply and transport capacity, coupled with a substantial increase in demand for natural gas and electricity. This, in turn, resulted in shortages of natural gas and electricity to residential users and, in particular, to industrial users, including Ternium Argentina, during seasons of high demand. Ternium Argentina’s operations experienced constraints in their natural gas

21

supply requirements and interruptions in their electricity supply at peak hours on many occasions. If natural gas and electricity supply and transport capacity fail to cover the demand for natural gas and electricity on a timely basis, Ternium Argentina’s local production (or that of its main customers and suppliers) could be curtailed, and Ternium Argentina’s sales and revenues could decline, which may adversely affect Ternium Argentina’s results of operations. For further information, see “—Risks Relating to the Steel Industry—Price fluctuations, shortages or disruptions in the supply of raw materials, slabs, energy and other inputs could adversely affect Ternium’s profitability” above.

Certain Regulatory Risks And Litigation Risks

International trade actions or regulations and trade-related legal proceedings could adversely affect Ternium’s sales, revenues and overall business.

International trade-related administrative proceedings, legal actions and restrictions pose a constant risk for Ternium’s international operations and sales throughout the world. Ternium purchases steel products, including significant quantities of steel slabs, from different foreign steel suppliers for its operations in Mexico, Colombia and Argentina. The Mexican, Argentine or Colombian governments may impose or increase duties on steel products imports. Trade liberalization, mainly through free trade agreements, can reduce certain input costs and increase access to foreign markets. On the other hand, greater trade liberalization in Ternium’s domestic markets increases competition. During the last decade, steel exports surged as a consequence of a global downturn and the economic slowdown in China, and the number of antidumping, countervailing, safeguard measures and other trade restrictive actions increased substantially. Accordingly, producers that were restricted from certain markets sought alternative markets for their products. If steel exports were to surge again in the future, Ternium’s share in domestic markets could be eroded by imports, and such market share losses may not be completely offset by increased exports to foreign markets.

Countries may impose restrictive import duties and other restrictions on imports under various trade related laws, such as national security, environmental and intellectual property regulations. The timing and nature of the imposition of trade-related restrictions potentially affecting Ternium’s exports are unpredictable. Trade restrictions on Ternium’s exports could adversely impact Ternium’s ability to sell products abroad and, as a result, Ternium’s profit margins, financial condition and overall business could suffer. One significant source of trade restrictions is unfair competition that could result in the imposition of “antidumping” and “countervailing” duties, as well as “safeguard measures”. These duties can severely limit or altogether prevent exports to relevant markets. In several of Ternium’s export destinations, such as the United States or Europe, safeguard duties and other protective measures have been imposed against a large number of steel imports, such as a 25% tariff on certain steel imports imposed by the United States in 2018. For further information, see Item 4. “Information on the Company-B. Business Overview Regulations-Trade Regulations”.

In addition, certain domestic producers have filed antidumping and/or countervailing duty actions against certain steel imports. Some of these actions have led, or may lead, to restrictions on Ternium’s sales of steel products to certain steel markets and result in lower profit margins. Antidumping and/or countervailing duty actions and other government actions are largely unpredictable and additional duties or restrictions could be imposed in the future, limiting Ternium’s sales to and potential growth in those markets, and increasing costs.

The cost of complying with environmental regulations and potential environmental and product liabilities may increase Ternium’s operating costs and negatively impact Ternium’s business, financial condition, results of operations and prospects.

Ternium’s steelmaking and mining activities are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees relating to the protection of human health and the environment, including laws and regulations relating to hazardous materials and radioactive materials and environmental protection governing air emissions, water discharges and waste management due to the risks inherent in the industries in which Ternium operates. Laws and regulations protecting the environment have become increasingly complex and more stringent in recent years, leading to higher compliance costs.

Furthermore, environmental laws and regulations may, in some cases, impose strict liability for damages to natural resources or threats to public health and safety without regard to negligence or fault. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances. Such laws and regulations may expose Ternium to liability for the conduct of, or conditions caused by, third parties or for actions that complied with applicable laws at the time they were performed.

22

While Ternium incurs and will continue to incur expenditures to comply with applicable laws and regulations, there always remains a risk that environmental incidents or accidents may occur that may negatively affect Ternium's reputation or operations. Some of the activities for which Ternium supplies products, such as production of food cans, construction and the automotive industry, are subject to inherent risks that could result in death, personal injury, property damage or environmental pollution, and result in product liability risks that could extend to liability for damages caused by such products. Furthermore, Ternium’s products are also sold to, and used in, certain safety-critical appliances. Actual or claimed defects in Ternium’s products may give rise to claims for losses suffered by customers and expose Ternium to claims for damages. The insurance Ternium maintains will not be available in cases of gross negligence or willful misconduct; in other cases, insurance may not be adequate or available to protect Ternium in the event of a claim, its coverage may be limited, canceled or otherwise terminated, or the amount of insurance may be less than the related impact on enterprise value after a loss.

Climate change legislation and increasing climate regulatory requirements aimed at transitioning to a lower-carbon economy could result in unexpected capital expenditures and costs, negatively affect the Company's competitiveness, reducing its market share and results of operations, and hampering its ability to access adequate financial resources.

There is an increased attention on greenhouse gas (“GHG”) emissions and climate change from different sectors of society. The Paris Agreement, adopted at the 2015 United Nations Climate Conference, sets out the global framework to limit the rising temperature of the planet and to strengthen the countries’ ability to deal with the effects of climate change. The European Green Deal, launched in 2019, focuses on adopting the required policies and measures aimed at reaching zero GHG emissions in Europe by 2050. In 2021, the European Commission made a formal proposal for an EU Carbon Border Adjustment Mechanism, aimed at avoiding carbon leakage from the EU and promoting emissions reductions worldwide.

Government initiatives to reduce GHG emissions, such as the introduction of a carbon tax or carbon-pricing systems, the adoption of “cap-and-trade” systems or other measures to promote the use of renewable energy sources could affect steel production costs. In Argentina, the 2017 tax reform introduced a tax on certain fossil fuels. Natural gas, considered the cleanest fossil fuel, was excluded from such tax. Metallurgical coal and petrochemical coke were exempted as long as they are used as part of an industrial process, other than for energy generation. Effective since March 2018, the tax on fossil fuels is set to increase 10% every year until 2028, when it is expected to reach an average $10 per ton of carbon dioxide equivalent emitted. Similarly, in 2013, Mexico approved carbon taxing rules applicable to fossil fuels (setting a zero tax on natural gas) and in 2019 the government implemented a pilot program for the adoption of an Emissions Trading System (ETS) aimed at reducing GHG emissions, by setting a cap on emissions and allowing for the trade of emission certificates. Although existing carbon pricing mechanisms in Mexico and Argentina do not materially limit or penalize Ternium’s GHG emissions, new carbon pricing mechanisms could be established, increasing Ternium’s production costs.

In addition, the Brazilian congress has been discussing initiatives to introduce carbon emission taxes on industry processes and power generation facilities, which, if applicable to Ternium’s steel production in Brazil, would result in incremental costs. Such increases in costs could affect, in turn, Ternium’s profitability and net results.

If there is no meaningful progress in lowering emissions in the years ahead, there is an increased likelihood of abrupt policy interventions as governments attempt to meet their environmental goals by adopting policy, legal, technology and market changes in the transition to a low-carbon global economy. In addition to incremental production costs, the adoption of new climate change legislation in the countries in which Ternium operates could result in incremental compliance costs and unexpected capital expenditures, affect Ternium’s competitiveness and reduce its market share and results of operations. Shifts in customer preferences and failure to respond to stakeholders’ demands for climate-related measures and environmental standards could harm Ternium’s reputation, adversely affect the ability or willingness of customers or suppliers to do business with Ternium, erode stakeholder support and restrict or reduce access to financial resources.

Risks Relating To the Company's ADSs

The market price for the Company's ADSs could be highly volatile.

Volatility in the price of the Company’s ADSs may be caused by factors within or outside of the Company’s control and may be unrelated or disproportionate to the Company’s operating results. In particular, the announcement of

23

potentially adverse developments, such as proposed regulatory changes, new government investigations or the commencement or threat of litigation against Ternium, as well as the announcement of transactions, investments, or changes in strategies or business plans of Ternium or its competitors, could adversely affect the trading price of the Company’s ADSs, regardless of the likely outcome of those developments. Broad market and industry factors could adversely affect the market price of the Company’s ADSs, regardless of their actual effect in operating performance. As an example of this volatility, a high closing price of $42.19 was reached on April 26, 2018, as steel prices in North America spiked reflecting the United States’ imposition of a 25% tariff on certain steel imports, but then fell to a low closing price of $9.84 on March 18, 2020, as the COVID-19 outbreak sent stock market prices sharply down, including the Company’s ADSs. Since then, the Company’s ADSs recovered and reached a high closing price of $56.19 on August 11, 2021, as steel prices reached record levels in the United States and Mexico, reflecting a recovery in steel demand that consistently outpaced steel production capacity restarts. The trading price of the Company’s ADSs could also suffer as a result of developments in emerging markets. Although the Company is organized as a Luxembourg corporation, almost all of its assets and operations are located in Latin America. Financial and securities markets for companies with a substantial portion of their assets and operations in Latin America are, to varying degrees, influenced by political, economic and market conditions in emerging market countries. Although market conditions are different in each country, investor reaction to developments in one country can have significant effects on the securities of issuers with assets or operations in other emerging markets, including Mexico, Brazil, Argentina and Colombia. See “Risks Relating to the Countries in Which Ternium Operates.”

Holders of shares or ADSs may not have access to as much information about the Company as they would in the case of a U.S. domestic issuer.

There may be less publicly available information about the Company than is regularly published by or about U.S. domestic issuers. Also, corporate and securities regulations governing Luxembourg companies may not be as extensive as those in effect in other jurisdictions, and U.S. securities regulations applicable to foreign private issuers, such as the Company, differ in certain respects from those applicable to U.S. domestic issuers. Furthermore, IFRS, the accounting standards in accordance with which the Company prepares its consolidated financial statements, differ in certain material aspects from U.S. GAAP. For a summary of the significant ways in which the Company's corporate governance practices differ from the corporate governance standards required for domestic companies by the New York Stock Exchange, or NYSE, see Item 16.G "Corporate Governance".

Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders.

Certain shareholders’ rights under Luxembourg law, including the right to participate and vote at general meetings of shareholders, to include items on the agenda for the general meetings of shareholders, to receive dividends and distributions, to bring actions, to examine books and records and to exercise appraisal rights may not be available to holders of ADSs, or may be subject to restrictions and special procedures for their exercise, as holders of ADSs only have those rights that are expressly granted to them in the deposit agreement. The Bank of New York Mellon, or BNY Mellon, as depositary under the ADS deposit agreement, through its custodian agent, is the registered shareholder of the deposited shares underlying the ADSs and therefore only the Depositary can exercise the shareholders’ rights in connection with the deposited shares. For example, if the Company makes a distribution in the form of securities, the Depositary is allowed, at its discretion, to sell the right to acquire those securities on your behalf and to instead distribute the net proceeds to you. Also, under certain circumstances, such as the Company's failure to provide the Depositary with voting materials on a timely basis, you may not be able to vote at general meetings of shareholders by giving instructions to the Depositary. If the Depositary does not receive voting instructions from the holder of ADSs by the prescribed deadline, or the instructions are not in proper form, then the Depositary shall deem such holder of ADSs to have instructed the Depositary to vote the underlying shares represented by ADSs in favor of any proposals or recommendations of the Company (including any recommendation by the Company to vote such underlying shares on any given issue in accordance with the majority shareholder vote on that issue) for which purposes the depositary shall issue a proxy to a person appointed by the Company to vote such underlying shares represented by ADSs in favor of any proposals or recommendations of the Company. Under the ADS deposit agreement, no instruction shall be deemed given and no proxy shall be given with respect to any matter as to which the Company informs the Depositary that (x) it does not wish such proxy given, (y) substantial opposition exists, or (z) the matter materially and adversely affects the rights of the holders of ADSs.

Holders of shares and ADSs in the United States may not be able to exercise preemptive rights in certain cases.

Pursuant to Luxembourg corporate law, existing shareholders of the Company are generally entitled to preferential subscription rights (preemptive rights) in the event of capital increases and issues of shares against cash contributions.

24

Under the Company’s articles of association, the board of directors has been authorized for a five-year period (ending in June 2025) to waive, limit or suppress such preemptive subscription rights. Notwithstanding the waiver of any preemptive subscription rights, for as long as the shares of the Company are listed on a regulated market, any issuance of shares for cash within the limits of the authorized share capital shall be subject to the preemptive subscription rights of existing shareholders, except (i) any issuance of shares for, within, in conjunction with or related to, an initial public offering of the shares of the Company on one or more regulated markets (in one or more instances); (ii) any issuance of shares against a contribution other than in cash; (iii) any issuance of shares upon conversion of convertible bonds or other instruments convertible into shares of the Company; provided, however, that the preemptive subscription rights of the then-existing shareholders shall apply in connection with any issuance of convertible bonds or other instruments convertible into shares of the Company for cash; and (iv) any issuance of shares (including by way of free shares or at discount), up to an amount of 1.5% of the issued share capital of the Company, to directors, officers, agents, employees of the Company, its direct or indirect subsidiaries or its affiliates (collectively the "Beneficiaries"), including without limitation, the direct issuance of shares or upon the exercise of options, rights convertible into shares or similar instruments convertible or exchangeable into shares, issued for the purpose of compensation or incentive of the Beneficiaries or in relation thereto (which the board of directors shall be authorized to issue upon such terms and conditions as it deems fit). For further details, see Item 10. “Additional Information—B. Memorandum and Articles of Association”.

Holders of ADSs in the United States may, in any event, not be able to exercise any preemptive rights, if granted, for shares underlying their ADSs unless additional shares and ADSs are registered under the U.S. Securities Act of 1933, as amended, or the Securities Act, with respect to those rights or an exemption from registration requirements of the Securities Act is available. The Company intends to evaluate, at the time of any rights offering, the costs and potential liabilities associated with the exercise by holders of shares and ADSs of the preemptive rights for shares, and any other factors it considers appropriate at the time, and then to make a decision as to whether to register additional shares. The Company may decide not to register any additional shares, requiring a sale by the Depositary of the holders’ rights and a distribution of the proceeds thereof. Should the Depositary not be permitted or otherwise be unable to sell preemptive rights, the rights may be allowed to lapse with no consideration to be received by the holders of the ADSs.

It may be difficult to obtain or enforce judgments against the Company outside Luxembourg.

The Company is a société anonyme organized under the laws of the Grand Duchy of Luxembourg, and most of its assets are located in other jurisdictions. Furthermore, most of the Company’s directors and officers reside in other jurisdictions. As a result, investors may not be able to effect service of process upon the Company or its directors or officers. Investors may also not be able to enforce against the Company or its directors or officers in the investors’ domestic courts, judgments predicated upon the civil liability provisions of the domestic laws of the investors’ home countries. Likewise, it may be difficult for investors not domiciled in Luxembourg to bring an original action in a Luxembourg court predicated upon the civil liability provisions of other securities laws, including U.S. federal securities laws, against the Company, its directors or its officers. There is also uncertainty with regard to the enforceability of original actions of civil liabilities predicated upon the civil liability provisions of securities laws, including U.S. federal securities laws, outside the jurisdiction where such judgments have been rendered; and enforceability will be subject to compliance with procedural requirements under applicable local law, including the condition that the judgment does not violate the public policy of the applicable jurisdiction.

Item 4.    Information on the Company

Overview

Ternium aims to have an active role in the world’s efforts to tackle climate change. As a steel company, we are determined to finding ways to reduce the carbon footprint of our operations and of the steel value chain. We partner with different companies and associations to foster the development of low carbon dioxide emitting technologies, as a swift and successful energy transition will be key to achieve these goals. We set a target to reduce by 20% the carbon dioxide emission intensity of our steelmaking facilities by 2030, compared to a 2018 baseline. The main initiatives we plan to carry out to achieve this objective are to increase the participation of renewable sources in the energy mix and of scrap in the metallic mix, to expand our carbon dioxide capture capacity at the DRI facilities, to partially replace metallurgical coal with biomass, to further develop our energy efficiency program and to prioritize lower specific-emission steelmaking technologies when planning organic expansions. We intend to develop new measures to continue decarbonizing Ternium’s operations over the longer term. The main factors that will determine our success to carry out our climate change strategy are related to the further development of emerging steelmaking technologies, prospects for the availability of raw materials, renewable energy and required infrastructure, and the enactment of appropriate government regulations to promote fair trade, among others. As a company focused on supplying advanced steel products, Ternium is well positioned to contribute to the world’s energy transition process. We believe the company will have significant opportunities for the development of innovative products required for renewable energy applications, emerging electric vehicles technologies and green construction strategies, as countries seek to meet their commitments under the Paris Agreement.

A.    History and Development of the Company

The Company

The Company is a société anonyme organized under the laws of the Grand-Duchy of Luxembourg. It was established on December 22, 2003. The Company’s registered office is located at 26 Boulevard Royal – 4th floor, L-2449 Luxembourg. Our agent for U.S. federal securities law purposes is Ternium U.S.A. Incorporated, located at 2200 West Loop South, Suite 945, Houston, TX 77027, United States.

Ternium

Ternium’s origins began in September 1961 with the founding of Propulsora Siderúrgica ("Propulsora"), by San Faustin’s predecessor in Argentina. Propulsora began its operations as a producer of cold-rolled coils in December 1969 and in the early 1990s began to evolve through a series of strategic investments aimed at transforming Propulsora into an integrated steel producer. In 1993, Propulsora merged with Aceros Paraná S.A. (a company formed by the Argentine government in connection with the privatization of Sociedad Mixta Siderúrgica Argentina ("Somisa"), at that time the main integrated producer of flat steel in Argentina) and three other affiliated steel industry companies.

26

After the merger, Propulsora changed its name to Siderar, and later to Ternium Argentina. San Faustin held a controlling interest in Siderar, with the remainder being held mainly by Usiminas, certain former employees of Somisa, and public investors.

In December 1997, a consortium formed by San Faustin, Ternium Argentina, Usiminas, Hylsamex, and Siderurgica Venezolana S.A. ("Sivensa"), won the bid in the privatization of a controlling interest in Sidor C.A. ("Sidor"), the largest steel company in Venezuela.

As part of a multiple-step corporate reorganization in 2005, San Faustin reorganized its investments in steel manufacturing, processing and distribution businesses by contributing to the Company San Faustin’s controlling interests in Ternium Argentina and other subsidiaries, in exchange for shares of the Company. In addition, Usiminas and Sivensa exchanged their interests in Ternium Argentina, Sidor and other subsidiaries for shares of the Company. In 2005, we acquired, together with Ternium Argentina, an indirect 99.3% interest in the Mexican company Hylsamex and its subsidiaries.

On January 11, 2006, the Company launched an initial public offering of 24,844,720 ADSs, each representing 10 shares of the Company, in the United States, and subsequently granted the underwriters of the Company’s initial public offering an option to purchase up to 3,726,708 additional ADSs to cover over-allotments in the sale of the ADSs.

On December 28, 2006, we acquired an additional 4.85% interest in Ternium Argentina from CVRD Internacional S.A, thereby increasing our ownership interest in Ternium Argentina to 60.93%.

On April 29, 2007, the Company acquired Grupo Imsa through a cash tender offer and a cash redemption. Grupo Imsa was renamed Ternium Mexico and, effective March 31, 2008, Hylsamex merged with and into Ternium Mexico. In connection with this merger, Ternium Argentina acquired, and currently holds, a 28.73% participation in Ternium Mexico.

On April 29, 2008, the National Assembly of Venezuela passed a resolution declaring that the shares of Sidor, together with all of its assets, were of public and social interest, and authorizing the Venezuelan government to take any action it deemed appropriate in connection with any such assets, including expropriation. On May 11, 2008, the President of Venezuela issued Decree Law 6058 ordering that Sidor and its subsidiaries and associated companies were transformed into state-owned enterprises (“empresas del Estado”), with Venezuela owning not less than 60% of their share capital. On May 7, 2009, Ternium completed the transfer of its entire 59.7% interest in Sidor to Corporación Venezolana de Guayana, a Venezuelan state-owned entity.

On August 25, 2010, Ternium completed the acquisition of a 54% ownership interest in Ferrasa and, indirectly, in its wholly-owned Colombian subsidiaries, Siderúrgica de Caldas S.A.S. and Perfilamos del Cauca S.A.S. On April 7, 2015, Ternium acquired the remaining 46% minority interest in Ferrasa. Through this investment, Ternium expanded its business and commercial presence in Colombia. In 2017, Ferrasa was renamed Ternium Colombia.

In November 2010, Ternium and NSC established Tenigal, with each company holding 51% and 49% participations, respectively. Tenigal completed the construction of a hot dip galvanizing plant in the vicinity of Monterrey City, Mexico, which commenced production in the third quarter of 2013. Tenigal was designed to produce high grade and high quality galvanized and galvannealed automotive steel sheets, including outer panel and high strength qualities.

On January 16, 2012, the Company’s subsidiaries Ternium Investments and Ternium Argentina (together with its wholly-owned subsidiary Prosid Investments S.A., or "Prosid", and the Company’s affiliate, Confab Industrial S.A., a subsidiary of Tenaris, or TenarisConfab), joined the existing control group of Usiminas, a leading steel company in the Brazilian flat steel market, through the acquisition of 84.7, 30.0, and 25.0 million ordinary shares, respectively, and formed the so-called Ternium/Tenaris (T/T) Group.

On October 30, 2014, Ternium Investments acquired 51.4 million additional ordinary shares of Usiminas. On April 20, 2016, Ternium Investments subscribed to 7.0 million preferred shares of Usiminas and Ternium Argentina, together with Prosid, subscribed to an aggregate 1.5 million preferred shares of Usiminas. On July 19, 2016, Usiminas’ extraordinary general shareholders’ meeting homologated a capital increase, and Ternium Investments acquired 62.6 million additional ordinary shares, and Ternium Argentina and Prosid acquired an aggregate 13.8 million additional ordinary shares. As a result of these transactions, Ternium, through its subsidiaries Ternium Investments, Ternium Argentina and Prosid, currently owns 242.6 million ordinary shares of Usiminas (representing 34.4% of Usiminas’ ordinary shares) and 8.5 million of Usiminas’ preferred shares (representing 1.6% of Usiminas’ preferred shares), representing, in the aggregate, 20.4% of Usiminas’ share capital. Ternium Investments, Ternium Argentina, Prosid and

27

TenarisConfab are parties to an Usiminas shareholders’ agreement, effective as of April 10, 2018, with NSC, Mitsubishi Corporation do Brasil S.A. and Metal One Corporation (comprising the so-called "NSC Group") and Previdência Usiminas, governing their rights and obligations as shareholders of Usiminas. For further information on our investment in Usiminas, see “—C. Organizational Structure—Other Investments—Usiminas.”

On September 7, 2017, the Company acquired a 100% ownership interest in thyssenkrupp Slab International B.V or tkSI, and its wholly-owned subsidiary CSA from thyssenkrupp AG, or tkAG. Through this investment, Ternium significantly expanded its steel slabs production capacity. As part of this process CSA was renamed Ternium Brasil Ltda. and tkSI was absorbed by the Company's fully-owned subsidiary Ternium Internacional España S.L.

B.    Business Overview

Our Business Strategy

Ternium aims to enhance stakeholder value by further consolidating its position as a leading steel producer in Latin America and a strong player in the Americas, while increasing its differentiation and strengthening its competitiveness. We believe Ternium has built competitive advantages in its main steel markets. Our industrial presence and network of distribution centers and commercial offices increase our ability to offer differentiated logistics and stock management services. Our customers have access to an integrated connectivity platform covering the entire customer relationship process. Ternium also works together with small and medium-sized customers and suppliers in Argentina and Mexico, through the ProPymes program, to help them grow. The prosperity of SMEs and the development of a collaborative industrial network have strengthened our value chain. This effort has led to a virtuous cycle of improved competitiveness, increased exports and imports substituted by new locally manufactured products.

Ternium’s differentiation initiatives have also included investments in state-of-the-art technologies. As part of this strategy Ternium has built its Pesquería Industrial Center in Mexico, which currently comprises a hot-rolling mill, a cold-rolling mill, two galvanizing facilities and a painting line. In addition, Ternium has recently announced the construction at this center of a new cold rolling mill, a hot-dip galvanizing line, a pushpull pickling line and new finishing lines with total capital investment of approximately $1 billion and expected start-up of operations in the first half of 2024. In 2021, Ternium inaugurated a new research and development center in Pesquería. This will enable us to speed up the development of new high-end steel products to be processed in the new facilities in order to satisfy our industrial customers' requirements. Ternium provides technical assistance to its customers through its product research and development area, allowing to maximize the performance of its steel products and the efficiency of the manufacturing processes downstream in the steel industry value chain.

We believe that Ternium has additional growth opportunities in the USMCA trade region. In Mexico, increased steel consumption over the last decades gave way to an attractive steel market with a significant demand for advanced steel products, mainly driven by a dynamic manufacturing industry that destines a significant share of its production to the U.S. market. The Mexican industrial sector has access to the U.S. and Canadian markets through the USMCA, and to other major economic regions and trade blocks through other free trade agreements. Mexico has privileged conditions to host a competitive and innovative manufacturing sector and the country’s geographic location provides a competitive logistics base to reach every major market. Mexican steel producers deliver approximately half of the flat steel demand in the country. We believe that Ternium is very well positioned to compete with foreign producers and gradually substitute imports in the country. Ternium has built a solid differentiation strategy leaning on its unique industrial presence in Mexico, as well as on its market competitiveness. We believe that Ternium is also well positioned to compete in the U.S. steel market.

In South America, Ternium has a significant presence in the Argentine steel market, the third largest in Latin America. The country's manufacturing customers account for approximately half of local flat steel demand, providing ample opportunities for the offering of value added products and services. Ternium has a solid differentiation strategy in Argentina built on its industrial integration in the country, which allows it to offer customized products and value-added services. Ternium also has a significant local presence in Colombia, the fourth largest steel market in Latin America. Ternium is also a competitive player in other steel markets in the region.

We identify three main elements of our business strategy: a focus on sophisticated value-added products, the pursuit of strategic growth opportunities and a relentless quest for competitive industrial operations.

•Focus on sophisticated steel products. The incorporation of new technologies, the development of new advanced steel products and the integration of our industrial system are elements of a strategy aimed at increasing the participation of higher margin value-added products in the company’s sales mix. Ternium’s industrial center in Pesquería strengthened our positioning in the high-end market sector, giving way to a gradual replacement of

28

imported goods in key industrial segments. The start-up of a new hot-rolling mill in this industrial center in July 2021 represented a technological leap forward in Mexico’s steel production capacity. With this, Ternium broadened its dimensional offerings with the most advanced steel grades, aiming at fulfilling all industry requirements to substitute high-value-added steel imports targeting the demanding and innovative automotive industry, as well as the home appliance, machinery, energy and construction sectors. The recently announced new investments in this industrial center will expand the facility’s advanced-high-strength and ultra-high-strength steels production capabilities, and help it better serve its customers in the automotive, renewable energy and home appliance industries, as well as in the construction and agricultural sectors. For further information on Ternium’s capital expenditures, see “—Capital Expenditure Program.”

•Pursuit of strategic growth opportunities. We have a history of strategically growing our businesses through acquisitions and organic growth. We intend to continue identifying and actively pursuing growth-enhancing strategic opportunities to consolidate Ternium’s presence in its main markets and expand it to the rest of the Americas, increase our industrial system integration, broaden our offerings of value-added products, and enhance our production and distribution capabilities. For example, in 2017, Ternium acquired the company that today is called Ternium Brazil, a steel slab producer with facilities located in the state of Rio de Janeiro, Brazil. The plant has an annual production capacity of 5.0 million tons of high-end steel slabs, a deep-water harbor and a 490 MW combined cycle power plant. With this acquisition, total crude steel production capacity of Ternium’s industrial system increased to 12.4 million tons, or approximately by 70%. The incorporation of the Rio de Janeiro facility triggered the expansion program in Pesquería, Mexico, that included the new hot-rolling mill to integrate the Brazilian slab facility to Ternium's industrial system. The combination of high-end steel slabs sourced form the Rio de Janeiro facility and a state-of-the-art hot-rolling mill in Pesquería, enables Ternium to increase its market share in Mexico with a combination of a higher production capacity, a broader dimensional offering, new advanced steel grades, enhanced customer service and reduced lead times in its value chain. The start-up of the new hot-rolling mill also opened-up new growth opportunities for downstream capacity at the Pesquería facility, like the announced construction of a new cold rolling mill, a hot-dip galvanizing line, a pushpull pickling line and new finishing lines. In Colombia, Ternium started up a new reinforcing bar facility in Palmar de Varela in 2020, adding 520,000 tons of annual production capacity of steel bars to Ternium’s industrial system. This investment allowed us to expand our market share in Colombia’s dynamic construction sector, by offering an alternative to imports in the country's northern region. In addition, it has increased our upstream integration in the country. For further information on Ternium’s capital expenditures, see “—Capital Expenditure Program.”

•Enhancement of Ternium’s competitive position. In addition to developing a full range of steel products and delivering differentiated services to Ternium’s customer base, we aim to enhance our competitive position by seeking excellence in operational performance, and by attracting and training talented employees. Our quest for operational excellence relies on the cross implementation of managerial, commercial and production best practices. Ternium has a centralized industrial engineering, automation, OH&S and environmental management area. Focused on capacity utilization, quality and maintenance, this area facilitates the improvement of production processes through best practices, a coordinated deployment of new technologies and access to strong internal technical support. Ternium’s broad range of value-added products, just-in-time delivery, inventory management and other services are offered to customers in major steel markets supported by our extended service centers, distribution channels, as well as sales and marketing networks. As part of its differentiation strategy, Ternium aims at further strengthening its presence at local steel markets. In this regard, in 2019 and 2020 Ternium put in place a total of seven new distribution centers in Mexico and Guatemala. We believe that the implementation of Ternium’s managerial, commercial and production best practices in acquired and new facilities and businesses should generate benefits and savings.

Our Sustainable Approach

We believe there are six value drivers that are key to achieve our goals in a sustainable way. These value drivers are:

- delivering on our business strategy;

- improving our safety performance;

- minimizing our environmental footprint;

- realizing our people’s full potential;

- helping communities thrive; and

- strengthening our value chain.

Improving our safety performance. We invest in occupational health and safety (OH&S) projects and manage OH&S matters based on the certainty that all injuries and work-related illnesses can and must be prevented. Risk assessment

29

and management of our people’s OH&S are integrated into all our business processes and reflected in Ternium’s OH&S policy. Management is responsible and accountable for OH&S performance as part of a broad set of goals. Ternium is committed to taking every measure to protect the safety and health of its employees, contractors and the communities where it operates. We design strategies to align our culture to our safety vision with the goal of preventing accidents, safely managing our production processes and engaging our employees and our customers and suppliers' managers and employees, through effective communication, so that they embrace our vision and goals. Each of our performance improvement strategies on OH&S is led by a senior manager.

Minimizing our environmental footprint. The protection of the environment is a fundamental value for Ternium. Our Environmental and Energy Policy expresses our commitment to the preservation of the environment. Ternium’s steel and mining operations are subject to environmental laws and regulations. Ternium’s corporate environmental and energy policy requires that each of its business units comply with applicable environmental laws and regulations, and aims to achieve the highest standards of environmental performance as a basis to ensure a sustainable development. Our environmental performance is monitored through an environmental and energy management system encompassing every production unit.

Ternium's environmental and energy management system is one of the key elements for pursuing excellence in environmental performance. Ternium periodically audits and certifies its systems and procedures. This process helps us identify improvement opportunities, update our environmental management processes and ensure compliance with applicable laws and regulations. Ternium’s steel production facilities environmental and energy management system is certified under ISO 14001. In addition, Ternium’s most demanding operations in terms of energy use are in the process of certifying their energy management system under ISO 50001. The energy management system has already been certified at the Rio de Janeiro unit, at the steel shop and hot-rolling mill of the San Nicolás unit and at the Pesquería unit, and is undergoing the certification process at the steel shop of the Guerrero unit.

In February 2021, Ternium adopted a new decarbonization strategy with a medium-term target to reduce its carbon dioxide emissions intensity rate by 20% in 2030, compared to its 2018 base rate of 1.7 tons of carbon dioxide per ton of steel. The company’s strategy to achieve this target is based upon a multi-faceted approach, including the intensified use of renewable energy at its facilities, increasing the participation of scrap in the metallic mix, increasing carbon capture capacity at the DRI facilities in Mexico, partially replacing coking coal with charcoal at the operations in Brazil and Argentina, developing energy efficiency strategies and prioritizing lower specific-emission steelmaking technologies. Of note in this regard, Ternium has completed the first phase of the project to increase the carbon capture capacity at the DRI facilities in Mexico, and has recently launched the second phase of this project. Ternium has also launched a project at the slab facility in Rio de Janeiro to increase the scrapyard processing capacity.

In addition, in 2021 the company announced a $460 million environmental investment plan to be deployed mostly over the next seven years. Investment projects are mainly related to improvements in particulate emissions control, raw material management and water quality control at the primary areas of the company’s operations in Mexico, Brazil and Argentina.

For further information on the environment, see Item 4. “Information on the Company —B. Business Overview — Regulations - Environmental Regulation”. For a description of some of the risks associated with the environment, health and safety, see Item 3. “Key Information—D. Risk Factors.”

Realizing our people’s full potential. The sustainability of Ternium’s performance relies on the competences and skills of existing and new employees and on a successful succession and continuity process. Ternium has a Career Development program and a Succession program for key positions as part of its initiatives to ensure its medium and long-term success. To achieve operational excellence, our teams pursue continuous improvement and innovation, and training is key to achieve this goal. Ternium centralized all training activities in a corporate university: Ternium University. It has the mission of learning, sharing and growing to help employees increase their competences and skills for their current and future positions at the company.

Ternium has adopted policies on Human Rights and Diversity and Work Environment Free of Harassment. We are an equal opportunity employer and aim to foster a workplace environment that attracts and develops talents across all genders, nationalities, generations, cultures, religions and backgrounds, respecting and valuing individual differences. Ternium’s Code of Conduct prohibits unlawful discrimination in employment relations and ensures that every person has the right to apply for employment with Ternium or to be considered for a new position strictly based only on the skills required for such task.

30

Helping communities thrive. We believe that an industrial project like Ternium’s can only be sustainable if community and industry grow together. This is the principle guiding our community programs, which focus on four main fields:

-    Education. We are convinced that education is the key to prosperous community growth and thus we have developed and ran educational programs covering the entire school cycle, from elementary to post-graduate, helping children and youngsters to fulfill their potential and become active contributors to society. Our programs include the Roberto Rocca Technical Schools, the Technical Gene program, the AfterSchool Program and Roberto Rocca Scholarships.

-    Culture. As a multi-cultural and multi-lingual company, we enrich and broaden people’s cultural horizons in communities near our facilities, fostering diversity and inclusion by promoting cultural activities. Our programs include the Film Festival and the Photo Library.

-    Volunteer work. We encourage our employees to volunteer for community activities with a special focus on refurbishing schools, aimed at helping those in need and cultivating pride and integration in our communities. With this purpose, we developed the Volunteers in Action program.

-    Health. We seek to improve people’s quality of life and foster welfare. With this purpose, we fund infrastructure projects and improvements at hospitals and health care centers near our facilities.

Abiding by these general directives, our programs have been designed to be implemented at local level, taking into account the particular circumstances of each community where we operate.

Strengthening our value chain. Ternium offers support to small and medium size enterprises (SMEs) through a program that provides a variety of services, including training, industrial assistance, institutional assistance, commercial support and financial aid. With the participation of approximately 1,830 companies, our ProPymes program fosters the development of the industrial value chain in Mexico and Argentina. ProPymes has helped create an industrial network that encourages the professionalization and quest for excellence of SMEs, which, based on knowledge sharing, reciprocal learning and exchange of experiences, aims at the implementation along the value chain of the best practices utilized in the industry.

Integrity. We believe integrity is key to Ternium’s long-term sustainability. With ethical behavior and compliance with law as a core value, we continuously work on building a corporate culture of transparency. The Company has adopted a Code of Conduct incorporating guidelines and standards of integrity and transparency that apply to all directors, officers and employees. As far as the nature of each relation permits, the principles described in the Code of Conduct also apply to relations with our contractors, subcontractors, suppliers and associated persons.

The Code of Conduct also includes guidelines related to the promotion of a healthy and safe workplace environment, respect for human and labor rights, the protection of the environment, our commitment to fair, honest and transparent competition, and the protection of data privacy of our employees and third parties with whom we conduct business. The Company has also adopted a Code of Ethics for Senior Financial Officers to supplement its Code of Conduct, which applies specifically to the chief executive officer, the chief financial officer, the chief accounting officer or controller, or other persons performing similar functions. In addition, the Company has adopted a Transparency Policy governing relationships with third parties, a Policy on Business Conduct, a Code of Conduct for Suppliers, an Anti-fraud Policy, a Policy on Securities Trading, a Policy on Financial and Accounting Controls, and a Policy on Personal Data Protection. As a condition for employment, certain employees must acknowledge and commit to comply with Ternium’s Code of Conduct and Policy on Business Conduct.

In the mining segment, iron ore is sold as concentrates (fines) and pellets.

Steel products

Slabs, billets and round bars: these products are semi-finished steel forms with dimensions suitable for its processing into specific product types. Slabs are processed into hot-rolled flat products. The use of slabs is determined by their dimensions and by their chemical and metallurgical characteristics. Billets are processed into long steel products, such as wire rods, bars and other shapes. Round bars are processed into seamless tubes.

Hot-rolled products: hot-rolled flat products are used by a variety of industrial consumers in applications such as the manufacturing of wheels, auto parts, pipes, gas cylinders and containers. They are also directly used for the construction of buildings, bridges and railroad cars, and for the chassis of trucks and automobiles. Hot-rolled flat products can be supplied as coils, strips or as sheets cut to a specific length. These products also serve as inputs for the production of cold-rolled products. Merchant bars include specific shape features, such as rounds, flats, angles, squares and channels, which are used by customers to manufacture a wide variety of products such as furniture, stair railings and farm equipment. Reinforcing bars (rebars) and stirrups, obtained from the mechanical transformation of rebars, are used to strengthen concrete highways, bridges and buildings. Rods are commonly drawn into wire products or used to make bolts and nails. Wire rod can be produced in different qualities according to customers’ demands.

Cold-rolled products: cold-rolled products are applied mainly to the automotive, home appliance and capital goods industries, as well as to galvanizers, drummers, distributors and service centers. Cold-rolled coils are sold as coils or cut into sheets or blanks to meet customers’ needs. These products also serve as inputs for the production of coated products.

Coated products: galvanized sheets are produced by adding a layer of zinc to cold-rolled coils, which are afterwards cut into sheets. Galvanized sheets are used in the automotive, construction and home appliances industries. Galvanized coils can also be further processed with a color coating to produce pre-painted sheets, resulting in a product that is mainly sold for building coverings, manufacturing of ceiling systems, panels, air conditioning ducts, refrigerators, air conditioners, washing machines and several other uses. Ternium also offers a distinctive type of galvanized product with coating composition that contains approximately 55% aluminum and 44% zinc to improve product performance for the construction industry, including rural, industrial and marine sites. Tinplate, given its resistance to corrosion and its mechanical and chemical characteristics, is mainly sold to the packaging industry for food canning, sprays and paint containers. Tinplate is produced by coating cold-rolled coils with a layer of tin.

Roll-formed and tubular products: these products include tubes for general use, structural tubes, tubes for mechanical applications, conduction tubes, conduction electrical tubes, oil tubes and pre-engineered metal building systems. Tubular products, uncoated or galvanized, have applications in several sectors including home accessories, furniture, scaffolding, automotive, bicycles, hospital equipment, posts for wire mesh garden and poultry tools, handrails, guard-rails, agricultural machinery, industrial equipment, conduction of water, air, gas, oil, high-pressure liquids and special fluids and internal building electrical installations. Beams, including C and Z section steel profiles (purlings) and tubular section beams, are obtained by roll-forming of steel strips and have applications in window frames, stilts, mainstays, crossbeams, building structures, supports, guides and crossbars for installing windows, doors, frames and boards. Other products include insulated panels, roofing and cladding, roof tiles and steel decks. Obtained from the mechanical transformation of flat steel, uncoated, galvanized or pre-painted, these products are used mainly in the construction industry in warehouses, commercial and industrial refrigeration installations, grain storage, poultry and porcine confinement facilities, roofing and side walls for buildings, and terraces and mezzanine floorings. Pre-engineered metal building systems are steel construction systems designed for use in low-rise non-residential buildings, and are constructed from the mechanical transformation of flat steel such as frames, secondary steel members, roofs and walls panels, as well as finishing and accessories.

Other products: other products include mainly electricity and pig iron. Pig iron is a semi-finished product obtained in the blast furnace that is mostly used as metallic charge in the steel shop for the production of crude steel, and also marketed to other steel producers and to manufacturers of iron-based cast products.

Within each of the basic product categories, there is a range of different “items” of varying qualities and prices that are produced either to meet the particular requirements of end users or sold as commodity items.

Iron ore products

Concentrates (fines) and pellets: These products are raw materials used for the production of steel. Iron ore concentrates are iron ore fines with high iron content. Iron ore pellets are produced from iron ore concentrates.

32

Ternium ships most of the pellets to its own steel manufacturing operations and it also markets the surplus portion of its iron ore pellets and concentrates, if any, to other steel manufacturers.

Production Facilities and Processes

Ternium has steel production facilities, service centers, distribution centers, or DCs, and mining operations in Mexico, steel production facilities and service centers in the Southern Region, and steel production facilities, service centers and DCs in other markets, specifically Brazil, Colombia, the United States and Central America.

Location Map of Las Encinas and Consorcio Peña Colorada’s Active Mines

Las Encinas

Las Encinas produces iron ore pellets and magnetite concentrate in Mexico. At present, Las Encinas operates the Aquila and Palomas open pit mines located in Michoacán and Jalisco, respectively.

40

Las Encinas facilities include two crushing plants (located close to each of the Aquila and El Encino mines), and a concentration and pelletizing plant located in Alzada, Colima, approximately 160 kilometers from the Aquila mine. Its major processing facilities (crushing, concentration and pelletizing facilities) include two primary crushers and a dry cobbing plant located close to the Aquila mine, and horizontal and vertical ball mills and several stages of magnetic separation in the Alzada facilities. Las Encinas has two operational tailings dams in Alzada and an idled tailings dam located in Cerro Náhuatl.

The iron ore pre-concentrate is transported from the Aquila mine to a transfer station at Tecoman, Colima, by truck and from Tecoman to the Alzada facilities by rail and truck for processing in the concentration plant. The iron ore extracted from the Palomas mine is currently transported by truck to El Encino to be processed in our crushing facility. In addition, El Encino and our plant located in Alzada may receive, from time to time, magnetite iron ore purchased by Las Encinas from other local concessionaires. The crushed iron ore is transported from El Encino to the Alzada facilities by truck for processing in the concentration plant in Alzada.The iron ore pellets produced in the Alzada facilities are transported by rail to Ternium Mexico’s integrated facilities in Monterrey and Puebla, Mexico. The Aquila and El Encino operations and the Alzada facilities receive electrical power from the Comisión Federal de Electricidad ("CFE"), the Mexican state-owned electric utility company.

Active mines

At the Aquila site, Las Encinas holds all the mining rights for the extraction of iron ore. The Aquila operations (including an open pit mine and crushing facilities) stand on 586 hectares, which are leased to Las Encinas by the local community of San Miguel de Aquila. The lease agreement allows Las Encinas to perform all mining activities, including the extraction of iron ore, necessary to exploit the ore located in mining rights granted to Las Encinas by the Mexican federal authorities until the permanent closure of the mine. Las Encinas has operated this mine since 1998.

Aquila is a mine composed predominantly of magnetite with a hematite roof and sulphides and silicates gangue. The form of mineralization is massive and disseminated (mineralized hornfels, endoeskarn), with mineralized gaps. The mine site is hosted along a large failure line and between the contact of an intrusive diorite and limestone, and the shape of the deposit is slightly amorphous, crossed by a countless number of dams and mainly controlled by geological structures.

At the Pihuamo-Tecalitán Palomas Mine, Las Encinas holds mining rights for the extraction of iron ore over 376 hectares. The Palomas operations (an open pit mine) stand on an area owned by Las Encinas, which started operating this mine in 2017.

Palomas is a skarn mine with calcareous-pelitic ferrous type. It is formed by massive, and bordered by disseminated mineral. The bodies are disposed in concordant tabular horizons with a northwest and southeast-oriented pseudo stratification and northeast-oriented dip. The mineralization is predominantly magnetite and the gangue mineral is composed of garnet, pyrite and calcite. The surrounding rocks are skarn (calcareous protolyte, clayey calcareous and Cretaceous sandy) or hornfels (clayey protolyte). The stratigraphic sequence is affected by dyke intrusions of monzonitic and granite composition.

Reserve and resource estimates at Las Encinas mines are based on a long-term iron ore reference price of $75 per dry metric ton for 62% ferrous CFR China, adjusted for grade, logistics, and other adjustments.

Areas under exploration

Las Encinas holds mining rights over other areas scattered throughout Michoacán, Jalisco and Colima, Mexico. Las Encinas has developed and may continue pursuing the development of small to mid-sized mining operations similar to Palomas, as a way to diversify its sources of iron ore and to make effective use of its mining rights in the region.

Exhausted mines

The El Chilillo open pit mine was operated until 2015. The El Chilillo core reserves were exhausted, the mine’s operations were suspended and the land returned to the owners. Ternium has already completed the requisite restoration works and has filed the applicable report with the environmental authority.

The El Encino open pit and underground mine was operated until 2011. The El Encino core reserves were exhausted and the mine’s operations have been suspended. Ternium is currently evaluating the steps required to proceed with its permanent closure. The crushing and transfer facilities at El Encino are still in operation and will remain active to receive, process and transfer to the Alzada pelletizing plant iron ore that Las Encinas buys from time to time from other local concessionaires.

41

The Cerro Nahuatl open pit mine located in Colima, Mexico, operated until 2008. The Cerro Nahuatl core reserves were exhausted and the mine’s operation has been suspended. Ternium is currently following the steps required to proceed with its permanent closure.

Consorcio Peña Colorada

Consorcio Peña Colorada, a company owned 50% by Ternium and 50% by ArcelorMittal S.A. ("ArcelorMittal"), produces iron ore pellets and magnetite concentrate in Mexico. Consorcio Peña Colorada operates the Peña Colorada open pit mine as well as a concentrating facility and a two-line pelletizing facility. Consorcio Peña Colorada owns part of the property where its mine and processing facilities stand, and leases 1,204 hectares adjacent to the mine to deposit removed material and, in the future, to exploit ore reserves as part of the regular short-term and long-term life of mine plan.

Consorcio Peña Colorada has operated since 1974 and holds mining rights over 39,980 hectares. The Peña Colorada mine is a complex polyphase iron ore deposit. Several magmatic and hydrothermal events produced iron mineralization as skarns or skarnoids, and late dikes and faults that crosscut the mineralized bodies. The main mineralization events are a massive ore body and a disseminated ore body, within polymictic breccia zones. Reserve estimates at the Peña Colorada mine are based on a long-term iron ore reference price of $75 per dry metric ton for 62% ferrous CFR China, adjusted for grade, logistics, and other adjustments. Resource estimates are based on a three-year trailing average of $130 per dry metric ton for 62% ferrous CFR China, adjusted for grade, logistics, and other adjustments.

The concentration plant is located at the mine in Minatitlán, Colima, and the pelletizing plant is located near the Manzanillo seaport on the Pacific coast in Colima, 50 kilometers from Minatitlán. Consorcio Peña Colorada’s major processing facilities include a primary crusher, two autogenous mill, horizontal and vertical ball mills, several stages of magnetic separation and two pelletizing lines. The concentrate is sent as a pulp through a 45 kilometers-long pipeline from the mine and mineral processing plant in Minatitlán to the pelletizing plant in Manzanillo.

Consorcio Peña Colorada has an operational tailings dam in Arrayanal, Colima, and a tailings dam in the process of closure located in Guásimas, Colima, with limited use. A paste plant operates near the Arrayanal dam to help increase the solid content of tailings. The Peña Colorada mine and the pelletizing plant receive electrical power from CFE.

Ternium is required to buy from Consorcio Peña Colorada half of the mine’s annual production. For further information, see “—Raw Materials, Slabs, Energy and Other Inputs—Mexico—Iron Ore.” Iron ore concentrate and pellets sold to Ternium are shipped by rail from the mine to Ternium’s facilities in Mexico or exported to third parties through the Manzanillo port.

In 2021, operating income and net sales of Ternium’s mining segment represented 3.6% and 3.3% of the Company’s consolidated operating income and consolidated net sales, respectively. As of December 31, 2021, the property, plant and equipment value of Ternium’s mining segment represented 6.0% of the Company’s consolidated property, plant and equipment value. None of our iron ore mines is considered to be material on an individual basis.

The estimates of mineral resources and mineral reserves at our mines and projects have been prepared by qualified persons. The 2021 mineral resource and mineral reserve estimates at the Aquila and Las Palomas mining properties have been prepared by a qualified person who is employed by Ternium. SLR Consulting (Canada) Ltd. was contracted to audit the 2021 Mineral Resource and Mineral Reserve estimates for the Peña Colorada mine.

Iron ore mineral reserves

The table below details Ternium’s estimated proven and probable iron ore reserves as of December 31, 2021. The classification of the iron ore reserve estimates as proven or probable reflects the variability in the mineralization at the selected cut-off grade, the mining selectivity and the production rate and ability of the operation to blend the different ore types that may occur within each deposit. Reserves are reported as Run of Mine (ROM). Tonnage is reported on a wet metric ton basis.

(1)Metal refers to ferrous at Las Encinas’ mines and ferromanganese at the Peña Colorada mine.

(2)Reported figures are for Peña Colorada’s operation at Ternium’s 50% ownership interest in Consorcio Peña Colorada. In 2020, figures were reported on a 100% basis.

The table below provides additional information on iron ore production and average estimated mine life.

Operations/Projects	% Ownership	In Operation Since	2021 Run of Mine Production (million tons)	2021 Saleable Production (million tons)(1)	Estimated Mine Life (Years)(2)
Las Encinas(3)	100	1970	4.5	1.9	6
Consorcio Peña Colorada(4)	50	1974	5.9	2.1	17

(1)Saleable production consists of a mix of direct shipped ore (DSO), concentrate, pellet feed and pellet products which have an iron content of approximately 65% to 66%.

(2)Mine life is derived from the life of mine plans and corresponds to the duration of the mine production scheduled from ore reserve estimates only. The production varies for each operation during the mine life and, as a result, the mine life is not necessarily the total reserve tonnage divided by the 2021 production. Both the Aquila and Palomas mines may extend their life beyond the estimated mine life indicated above as a result of iron resources not yet included as proven or probable reserves.

(3)In 2021 includes exclusively the Aquila and Palomas mines. Run of mine production in 2020 was 3.3 million tons and in 2019 was 2.3 million tons.

(4)Run of mine production in 2020 was 5.8 million tons and in 2019 was 3.9 million tons. Reported figures are for Peña Colorada’s operation at Ternium’s 50% ownership interest in Consorcio Peña Colorada. In 2020, figures were reported on a 100% basis.

Changes in iron ore reserve estimates (2021 versus 2020)

Las Encinas’s iron ore reserve estimates as of December 31, 2021 were 23 million tons on a run-of-mine basis (with an average iron grade of 39%), decreasing by 3 million tons compared to those recorded as of the end of 2020. The decrease in tonnage was mainly due to the depletion of reserves during 2021, partially offset by the incorporation of new reserves at the Aquila mine. Las Encinas is performing exploration activities at the Aquila mine in order to incorporate additional reserves, which are expected to extend its mine life.

Peña Colorada’s iron ore reserve estimates as of December 31, 2021 were 125 million tons on a run-of-mine basis (with an average iron grade of 22%), decreasing by 2 million tons compared to those recorded as of December 31, 2020. The decrease in tonnage was mainly due to the depletion of reserves during 2021, partially offset by the incorporation of new reserves at the Peña Colorada mine. Reported figures are for Peña Colorada’s operation at Ternium’s 50% ownership interest in Consorcio Peña Colorada.

The reserve calculations were prepared in compliance with the requirements of SEC rules, under which:

•Reserves are the part of a mineral deposit that could be economically and legally extracted or produced at the time of the reserve determination.

•Proven reserves are reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches or working or drill holes; grade and/or quality are computed from the results of detailed sampling; and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well established.

43

•Probable reserves are reserves for which quantity and grade and/or quality are computed from information similar to that used for proven reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.

The demonstration of economic viability is established through the application of a life of mine plan for each operation or project providing a positive net present value on a cash forward-looking basis. Economic viability is demonstrated using forecasts of operating and capital costs based on historical performance, with adjustments based on planned process improvements, changes in production volumes and in fixed and variable proportions of costs, and forecasted fluctuations in costs of raw material, supplies, energy and wages. Mineral reserve estimates are updated annually in order to reflect new geological information and current mine plan and business strategies. Our reserve estimates are of in-place material after adjustments for mining depletion and mining losses and recoveries, with no adjustments made for metal losses due to processing. For a description of risks relating to reserves and reserve estimates, see Item 3. “Key Information—D.Risk Factors—Risks Relating to Ternium's Mining Activities—Ternium's reserve estimates may differ materially from actually recoverable mineral quantities, or its estimates of mine life may prove inaccurate; and market price fluctuations and changes in operating and capital costs may render certain ore reserves uneconomical to mine in the future or cause Ternium to revise its reserve estimates.”

Our mining leases are of sufficient duration (or convey a legal right to renew for sufficient duration) to enable all ore reserves on the leased properties to be mined in accordance with current production schedules. Our ore reserves may include areas where some additional approvals remain outstanding but where, based on the technical investigations we carry out as part of our mine planning process and our knowledge and experience of the approvals process, we expect that such approvals will be obtained as part of the normal course of business and within the timeframe required by the current life of mine schedule.

Production process

44

Ternium specializes in manufacturing and processing finished steel products. In addition, Ternium extracts and processes iron ore and produces electricity.

Ternium’s facilities use different technologies and have different levels of integration. The basic inputs for steel production are iron ore and energy. Iron ore is used in three different formats: fines and lumps, which are purchased in the marketplace, and pellets, which are partly purchased in the marketplace and partly produced by Ternium. Ternium’s steel production processes consume energy mainly in the form of natural gas, coal and electricity.

Iron ore extraction and processing. The iron ore pellet production process begins with the extraction of iron ore from open pit mines owned and operated by Ternium in Mexico. The extraction process consists of removing waste and ore from the surface with explosives, loading it and transporting it by truck to the crushing facilities where it is resized to a specified size.

After crushing, the ore goes through several grinding and concentration stages. Grinding reduces the size and changes the shape of the ore while concentration, through magnetic drums, separates the iron from the sterile material to obtain an iron ore concentrate with high iron content. This process is carried out using water as an auxiliary element. Excess water is afterwards eliminated through a filtering process, leaving only the necessary humidity for the formation of pellets using pelletizing disks. Pellets are separated according to their size and are then hardened in ovens and shipped to the steel producing facilities.

Steel production. Ternium produces semi-finished steel in the form of thin slabs, slabs, billets and round bars through the blast furnace and the electric arc furnace methods.

Under the blast furnace method, which is used in Brazil and Argentina, iron ore pellets, lumps, sinter (a mixture of iron ore fines and limestone produced in sinter facilities) and coke (a solid residue obtained from the distillation of coal produced in coking batteries) are mixed in the blast furnaces in a process that melts and reduces the iron ore, obtaining pig iron. The molten pig iron is then mixed with steel scrap and other products in a basic oxygen furnace through a process that removes impurities from the pig iron by injecting pure oxygen at high pressure into the molten metal, burning-off carbon and other elements. The molten steel is then cast using the continuous casting method, into slabs.

Under the electric arc furnace method, which is used in Mexico and Colombia, the iron metal charge is heated with other elements to obtain molten steel. The molten steel is then cast, using the continuous casting method, into billets and thin slabs. The iron metal charge in the Apodaca and Manizales plants is steel scrap, and the iron metal charge in the Monterrey and Puebla plants is a mix of DRI and steel scrap. The DRI results from the conversion of pellets in the DRI modules. One of Monterrey’s DRI plants includes Hytemp® technology, which permits the hot discharge of the DRI to the electric arc furnace, generating significant energy savings and improving productivity.

Steel processing. Semi-finished steel is then processed into finished products using hot-rolling, cold-rolling, coating, tubing, paneling, slitting and cut-to-length facilities among other processes. In Mexico and Argentina, Ternium has been processing steel slabs produced in Ternium Brazil and/or purchased in the marketplace as in Mexico its steel processing capacity is higher than its steel production capacity, and in Argentina its steel processing capacity utilization has been higher in recent years than its steel production capacity. Ternium may purchase hot-rolled, cold-rolled and coated products as well for further processing in its lines.

Thin-slabs, slabs and billets are processed in the hot-rolling mills in Mexico, Argentina and Colombia to obtain hot-rolled products using different technologies. In the case of flat products, hot-rolled coils are obtained from thin or conventional slabs. Thin slab hot-rolling, a technology Ternium uses only in Mexico, requires less energy than conventional slab hot-rolling, as it does not require a roughing section at the mill and does not need to be reheated from room temperature to reach rolling temperature. In the production of long products, which is carried out in Mexico and Colombia, billets are reheated and taken to rolling temperature. The softened steel is processed in the rolling trains to obtain wire rods and rebars as finished long products and, depending on their final use, rebars can be further processed into stirrups and other customized shapes in our service centers in Colombia.

Depending on its final use, the hot-rolled coils are then tempered and/or pickled, both in Mexico and Argentina, before being sent for sale as coils or cut into steel sheets. Alternatively, the hot-rolled coils may be sent to a cold-rolling mill where they are put under a deformation process at room temperature to reduce their thickness and obtain cold-rolled coils. Cold-rolled coils can be sold in crude form to the market (full hard) or processed in the reheating ovens, annealing bays and temper lines to modify their metallurgic and physical characteristics. The tempered products can be sold as coils or sheets or further processed by adding coatings.

45

Cold-rolled coils can be further processed into tin plate at Ternium Argentina’s facility (by adding a thin layer of tin), into galvanized or electrogalvanized sheets at several of Ternium’s facilities in Mexico, the United States and Guatemala and at Ternium Argentina’s facility (by adding a thin layer of zinc to the products through different processes) or into pre-painted products. Some of these products can be further processed into slitted, cut-to-length and tailor-made products according to customers’ needs at Ternium’s service centers, which are located in several countries. In addition, coated, cold-rolled and hot-rolled coils can be further processed into tubular products, such as welded pipes, insulated panels and architectural panels, among other products.

We export iron ore through the Manzanillo port that is located on Mexico’s Pacific coast, mainly to customers in the Chinese iron ore market.

Competition

Steel

The steel industry operates predominantly on a regional basis, with large industry participants selling the bulk of their steel production in their home countries or regions, where they have natural advantages and are able to more effectively market value-added products and provide additional customized services. Despite the limitations associated with transportation costs, as well as the restrictive effects of protective tariffs and other trade restrictions, international trade of steel has increased in the last two decades with production shifting towards low-cost production regions.

49

Historically, several large steel manufacturers have merged with each other or acquired steel companies in other parts of the world. This wave of consolidation has resulted in a number of large, global producers with significant operations in several regions and/or continents, contributing to the increasing globalization of the steel industry. Considered as a whole, however, the steel industry still remains considerably fragmented, compared with market conditions characterizing certain of our suppliers and customers, e.g. iron ore suppliers and the automotive industry.

Steel consumption has historically been centered in developed economies, such as the United States, Western Europe and Japan. However, in the last two decades steel consumption in Asia, and in particular China, has increased significantly.

There has been a trend toward steel industry consolidation among Ternium’s competitors. Below is a summary of the most significant transactions:

•June 2006: Mittal Steel Company, N.V. and Arcelor S.A. merged to create ArcelorMittal, the world’s largest steel company.

50

•February 2022: Nucor Corporation completed the acquisition of a 51% ownership position in California Steel Industries, or CSI. CSI has become a joint venture between Nucor and JFE.

Despite this trend, the global steel market remains highly fragmented. In 2020, the most recent year for which statistics are available, the five largest steel producers, China Baowu Group, ArcelorMittal, HBIS Group, Shagang Group and NSC, accounted for 17% of total worldwide steel production, compared to 15% for the five largest steel producers in 2000.

Historically, steel prices have exhibited significant volatility. Events that contribute to continuously volatile steel price cycles include spikes and depressions in raw material prices, new steelmaking capacity additions (at a pace higher than steel demand growth), the idling and restart of steelmaking capacity and adverse economic conditions. In the US, for instance, steel prices trended down during most of 2018 and 2019, after peaking during the first half of 2018, as a result of softer steel consumption, increased steel production and, in 2019, lower costs of steel scrap. Steel prices decreased further in 2020 during the early stages of the COVID-19 pandemic reflecting a depression in steel consumption. However, after an initial slump, steel prices increased steadily during the rest of 2020 and picked at historical record levels in September 2021, as the speed of the recovery in steel production and in the production of steelmaking raw materials fell short of steel demand. Since then, steel prices decreased rapidly under a normalizing steel supply-demand balance scenario until February 2022, when they raised significantly following the start of the Russia-Ukraine armed conflict.

Mexico

Ternium competes in the Mexican steel market with domestic, United States and other foreign steel producers. According to the Mexican chamber of the iron and steel industry (Cámara Nacional de la Industria del Hierro y el Acero, or "Canacero"), imports of finished flat steel products into Mexico accounted for approximately 9.9, 7.6 and 8.5 million tons in 2021, 2020 and 2019, respectively.

Our largest Mexican competitor in the flat products market is AHMSA, an integrated steel producer located in Monclova, Coahuila, which produces a wide variety of steel products. AHMSA's financial condition has deteriorated, negatively affecting its operations. In 2020, AHMSA disclosed to the market that GAN had been negotiating a strategic alliance with Grupo Villacero with a focus on AHMSA’s recapitalization. In December 2020, AHMSA announced that certain shareholders of its parent company, GAN, agreed to sell 55% of GAN’s shares to Alianza Minero Metalúrgica Internacional S.A. de C.V. (AMMI), a company presumably controlled by other companies and investors, some of which could be competitors of Ternium in the steel market. In August 2021, AHMSA informed that the agreement with AMMI was revoked due to non-compliance of some clauses. Recently, AHMSA reported that continues working on establishing a capitalization or association agreement with possible partners within the framework of its financial restructuring process. Other competitors in Mexico, some of which are also customers, with facilities in the country are ArcelorMittal, which is ramping-up a hot-rolling mill; Galvasid S.A. de C.V. (controlled by Grupo LM), a producer of galvanized and pre-painted coils; Zincacero S.A. de C.V. (controlled by Grupo Villacero), a producer of galvanized and pre-painted coils; Posco, a Korean steel company with a galvanizing facility; NUCOR-JFE, a joint venture between Nucor Corporation and JFE Steel Corporation that operates a galvanizing facility; Talleres y Aceros S.A. de C.V., or TYASA, which has a flat steel Castrip® mill, a reversing cold-rolling mill and a galvanizing facility; and Grupo Acerero S.A. de C.V., or GASA, which operates a plate mill.

Our largest foreign competitors in the flat products market are Cleveland Cliff Inc.; Nucor Corporation; US Steel; ArcelorMittal-NSC, a joint venture between ArcelorMittal and NSC that operates the Calvert plant in Alabama, US; Steel Dynamics Incorporated, which is ramping-up a new steel mill in southern United States; and Posco.

In the rebar market, Ternium’s largest competitor is ArcelorMittal. To a lesser extent, Ternium also faces competition from Deacero S.A. de C.V., or Deacero, Grupo Simec S.A.B. de C.V., or Simec, controlled by Grupo ICH, TYASA, GASA and Gerdau Corsa. In the low-carbon wire rod market, Ternium’s main competitors are Deacero, ArcelorMittal and, to a lesser extent, TYASA, GASA and Simec.

In the small diameter welded pipe market, Ternium’s main competitors, which are also customers, are Productos Laminados de Monterrey S.A. de C.V., or Prolamsa and Grupo LM. Orders in this market are usually small and cover a wide range of product specifications.

Southern Region

Ternium’s most significant market in the Southern Region is Argentina, which in 2021 accounted for approximately 95% of sales in the Southern Region. Ternium Argentina is the main producer of flat-rolled steel products in Argentina. Its main competition in the Argentine flat steel market are imports, particularly from Brazil. The main

51

Brazilian producers of flat steel value-added products are Usiminas, Companhia Siderúrgica Nacional and ArcelorMittal. Ternium maintains a leading position in the flat steel market of Paraguay and is present in the flat steel markets of Bolivia, Chile and Uruguay, where the location of Ternium’s facilities in neighboring Argentina provides a logistical advantage to supply these markets vis-à-vis its foreign competitors.

Other Markets

Within the Other Markets region, Ternium’s most significant markets for finished steel products are Colombia, the southern United States and Central America. In addition, Ternium sells steel slabs to steel companies mainly in Brazil, such as Usiminas, and the US.

Through its Colombian subsidiaries, Ternium is the main flat steel processor in the country and is also one of the main long steel producer. Its main competitors in the Colombian steel market are Acerías Paz del Río, Gerdau Diaco, Acerías de Colombia, Siderúrgica Nacional and Siderúrgica del Occidente, and it also faces competition from imports.

Ternium has a very small participation in the U.S. steel market in comparison with U.S. domestic steel manufacturers and importers. It successfully competes in the Gulf Coast and a large portion of the West Coast where its facilities have logistical advantages.

Ternium maintains a significant position in the coated flat steel market of Central America, supported by logistical advantages provided by nearby facilities located in Costa Rica, El Salvador, Guatemala, Nicaragua and Mexico. In addition, Ternium keeps a presence in other markets in the Americas.

Mining

The majority of iron ore supplies to the international seaborne market come from Australia and Brazil, from the major global miners Vale, Rio Tinto BHP Billiton, Fortescue Metals Group and Anglo American, as well as from iron ore junior companies in these countries. In Mexico, the main iron ore producers are AHMSA, ArcelorMittal and Ternium, which are, at the same time, major steel-making companies and iron ore consumers. Only a small portion of the iron ore obtained by these three companies is made available for sale in the Mexican or export market. There are also other small iron ore mining concessionaries that sell their production mostly to local steel-making operations.

Capital Expenditure Program

The main objectives of Ternium’s current capital expenditure program are to:

•increase steel processing capacity;

•increase product range;

•reduce production costs;

Raw Materials, Slabs, Energy and Other Inputs

The main inputs for Ternium’s facilities are the following: in Mexico, slabs, iron ore, steel scrap, electricity and natural gas; in Brazil and Argentina, iron ore and metallurgical coal; and in Colombia, steel products, steel scrap and electricity. Below is a more complete description of the supply conditions for raw materials, slabs, billets, energy and other inputs at Ternium’s facilities in these countries. For a description of some of the risks associated with Ternium’s access to raw materials, energy and other inputs, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Steel Industry—The recent Russia-Ukraine armed conflict and the consequent wave of international sanctions against Russia are expected to reduce the supply of steelmaking raw materials and steel products in the international markets, including slabs and pulverized coal for injection, and certain metals and ferroalloys and Price fluctuations or shortages in the supply of raw materials, slabs, energy and other inputs could adversely affect Ternium’s profitability.”

Mexico

In Mexico, Ternium’s manufacturing of finished steel products relies on the supply of crude steel from its steelmaking facilities, which are based on the mini-mill technology, and on the purchase of crude steel slabs from third parties or from other Ternium subsidiaries. The mini-mill technology melts a variable combination of DRI and steel scrap to produce thin slabs, billets and round bars. Ternium’s production process in Mexico requires extensive use of natural gas and electricity. Purchased slabs are the largest component of production costs; iron ore, scrap, electricity and natural gas costs are also significant.

Slabs. Ternium’s Mexican subsidiaries have some non-integrated steel processing facilities that consume large quantities of slabs purchased from third-party suppliers or from other Ternium subsidiaries. Currently, slabs are purchased both in Mexico (primarily from ArcelorMittal) and in the international markets, including from Ternium Brasil and, from time to time, Ternium Argentina. Slab consumption could vary significantly from year to year in accordance with market conditions. Our Mexican subsidiaries purchased, either from third parties or from other Ternium facilities, 4.4 million, 3.0 million and 3.1 million tons of slabs in 2021, 2020 and 2019, respectively. Slab purchase prices are market-based. The armed conflict in Ukraine and the consequent wave of international sanctions against Russia could result in increased restrictions in the availability of steel slabs for Ternium Mexico's operations.

Iron ore. As described under “—Production Facilities and Processes—Mining Production Facilities” above, Ternium’s subsidiaries own interests in two mining companies in Mexico: 100% of the equity of Las Encinas and a 50% equity stake in Consorcio Peña Colorada. Under our arrangement with Consorcio Peña Colorada, we are committed to off-take 50% of the annual production of the Peña Colorada mine. In 2021, 3.5 million tons of iron ore were shipped from these two companies to Ternium’s Mexican steel production facilities, representing 100% of their iron ore requirements. In addition, Ternium shipped to third-parties 262,000 tons of iron ore. On average, we consume approximately 1.0 ton of iron ore to produce one ton of crude steel at our mini-mill facilities in Mexico.

Steel scrap. We source steel scrap from the Mexican market, through Ternium’s own steel scrap collecting and processing operations, and from the US market. Steel scrap is purchased at market prices. On average, we consume approximately 0.4 tons of scrap to produce one ton of crude steel at our mini-mill facilities in Mexico.

Electricity. Electric arc furnaces consume large quantities of electricity. In Mexico, Ternium purchases electricity from Techgen S.A. de C.V., or Techgen, and CFE.

Techgen owns a natural gas-fired combined cycle power plant in the Pesquería area of the State of Nuevo León, Mexico. Techgen is a joint venture company in which Ternium participates and contracts 78% of Techgen’s capacity of approximately 900 megawatts, or MW. As the capacity contracted by Ternium is significantly higher than the capacity currently required, Ternium resells unused electricity to the Mexican market. For further information on the Techgen investment, see “—C. Organizational Structure—Other investments—Techgen”.

Ternium used to purchase electricity from Iberdrola under supply contracts, with electricity purchases under these contracts being made at market prices less certain agreed discounts. Ternium's agreements with Iberdrola expired on January 31, 2022. For further information on Ternium’s former commitments with Iberdrola, see note 24(ii) (e) to the consolidated financial statements included in this annual report. On average, we consume approximately 0.6 megawatts-hour, or MWH of electricity to produce one ton of crude steel at our mini-mill facilities in Mexico.

In March 2021, the Mexican Congress approved a significant reform to the energy market in Mexico. Among other changes, the new Energy Industry Law (“LIE”) grants priority to Mexico’s state-owned electric power generation and distribution company (“CFE”) over private generation competitors in the supply of electric power to the Mexican market and mandates a revision of power generation and transaction agreements between CFE and independent electric power suppliers. In addition, the LIE eliminates mandatory power supply auctions for energy supplies

54

requiring the use of CFE’s distribution network, relaxes the requirements for the granting of clean energy certificates in favor of CFE, and imposes serious restrictions on the renewable energy generation system through self-supply, widely used by private companies. The new LIE was challenged in court and its application has been suspended as a consequence of the multiple constitutional review actions and injunctive measures filed by affected players. In September 2021, President Andrés Manuel López Obrador submitted to Congress a constitutional reform proposal of the electricity sector, which seeks to reverse the legal framework derived from the 2013 constitutional energy reform that opened the sector to private investment. The congressional debate on the reform started in January 2022 and two-thirds of the votes are required for approval. It is not certain that the constitutional reform and related amendments to the energy market regulation will be approved. Approval of proposed changes could negatively affect the operations of Techgen, the power plant in which Ternium holds a 48% equity interest and which supplies electricity for most of our Mexican operations. At this stage, we cannot fully assess the effects of the energy market reform on Ternium’s operations and the Mexican economy in general and, consequently, on the results of operations and financial conditions of our businesses in Mexico.

Natural gas. Natural gas is mainly used as a reducing agent for the production of DRI and for the reheating of slabs and billets before the hot-rolling process. Ternium has secured with Centro Nacional de Control del Gas Natural, the Mexican national center for natural gas control, natural gas transportation capacity on Sistema de Transporte y Almacenamiento Nacional Integrado de Gas Natural, the Mexican natural gas transportation grid. Ternium has also natural gas distribution agreements with Gas Industrial de Monterrey S.A. de C.V., or GIMSA, Compañía Mexicana de Gas S.A. de C.V. and Naturgy Mexico S.A. de C.V.

In addition, Ternium has a one-year renewable natural gas supply agreement with NEG Natural S.A. de C.V., or NEG, a subsidiary of Mexican conglomerate ALFA. Natural gas prices in Mexico are mainly based on the Houston Ship Channel reference price plus transportation, distribution and service costs depending on the location of the delivery points in Mexico. On average, we consume approximately 8.3 million btu of natural gas to produce one ton of crude steel at our mini-mill facilities in Mexico.

For additional information regarding inputs affecting our operations in Mexico, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Countries in Which Ternium Operate—Mexico” and “—Risks Relating to Ternium's Mining Activities.”

Brazil and Argentina

In Brazil and Argentina, Ternium produces crude steel through the use of blast furnace technology. The principal raw materials used to produce steel are iron ore, metallurgical coal and, in Ternium Brasil, pulverized coal. The manufacturing process also requires significant quantities of electricity and natural gas.

Iron ore. Iron ore is purchased under long-term agreements from suppliers in Brazil. Prices under these contracts are determined in accordance with market conditions. Our main suppliers of iron ore, in the form of lumps, pellets and sinter feed fines, are Vale and Vetria Mineração S.A. Our geographic location in Brazil provides favorable access to high quality iron ore pellets, lumps and fines produced in Brazil’s iron ore mines in the Southeast Region mainly, and our geographic location in Argentina provides favorable access to high quality iron ore lump and fines produced in Brazil’s iron ore mines in the Pantanal Region (Mato Grosso do Sul state). In addition, Ternium Argentina’s steelmaking facility receives iron ore pellets and fines from ports located on Brazil’s ocean coast. We consume approximately 1.5 tons of iron ore to produce one ton of crude steel in Brazil and approximately 1.4 tons of iron ore to produce one ton of crude steel in Argentina.

Metallurgical coal and related materials. Ternium Brasil and Ternium Argentina obtain their coke through the distillation in their coke ovens of metallurgical coal and petroleum coke. The facilities require different types of coal to produce coke. In addition, Ternium Brasil purchases other coal qualities to inject in the blast furnace. Coal is purchased under short-term contracts and on the spot market from several major international suppliers based mainly in Australia, the United States and Russia. The recent Russia-Ukraine armed conflict and the consequent wave of international sanctions against Russia could result in increased restrictions in the availability of pulverized coal for injection for Ternium Brasil's operations. Prices under contracts are determined in accordance with market conditions. Ternium purchases petroleum coke produced by oil companies in Argentina and Brazil. The volume purchased from each supplier mainly depends on the technical quality requirements of the blast furnace operations. We consume approximately 0.8 tons of metallurgical coal, pulverized coal and imported coke to produce one ton of crude steel in Brazil and 0.5 tons of metallurgical coal and petroleum coke to produce one ton of crude steel in Argentina.

Electricity. Ternium Brasil and Ternium Argentina consume large quantities of electricity for their manufacturing activities. The electricity required by Ternium Brasil is self-generated on site by its thermoelectric plant with an

55

installed power capacity of 490 MW, with excess electricity production sold in the Brazilian wholesale market. Part of the electricity required by Ternium Argentina’s San Nicolás facility is self-generated on site by a wholly-owned thermoelectric plant with an installed power capacity of 108 MW that operates with an utilization rate of approximately 75%. These thermoelectric plants use steam primarily generated from co-product gases obtained in the steelmaking process (blast furnace and coke oven gases).

Additional fuel requirements for steam production are covered with natural gas purchased from different market vendors and/or, in the case of Ternium Argentina, fuel oil bought at market prices. Ternium Argentina covers electricity shortfalls or sells surpluses, as the case may be, at spot prices with CAMMESA, the Argentine wholesale electricity market manager. Argentine laws establish that large energy consumers must increase the share of renewable energy consumption from 16% by 2022 to 20% by 2025. CAMMESA is responsible for meeting these renewable energy consumption targets for those large consumers that do not procure renewable energy from other sources. We purchase approximately 0.1 MWH of electricity to produce one ton of crude steel in Argentina.

Natural gas. Ternium Brasil and Ternium Argentina also consume substantial volumes of natural gas, particularly to operate their steel plants and power generation facilities. Ternium Brasil purchases natural gas at market prices from Companhia Distribuidora de Gás do Rio de Janeiro, or CEG. Ternium Brasil has a natural gas transportation and distribution agreement with CEG that is automatically renewed every year. We consume approximately 0.5 million btu of purchased natural gas to produce one ton of crude steel in Brazil.

Ternium Argentina purchases natural gas at market prices mainly from Tecpetrol S.A., a company in which San Faustin holds a controlling interest, Pluspetrol S.A., and natural gas traders, including MetroEnergía S.A., Natural Energy S.A., Energy Traders S.A., Gas Patagonia S.A. and Gas Meridional S.R.L. Over the course of the past several years, natural gas demand in Argentina increased significantly, outpacing supply and thus the provision of natural gas to industrial users (including Ternium Argentina) suffered restrictions during seasons of high demand. In recent years, natural gas restrictions have been relatively low. However, the Russia-Ukraine armed conflict and the consequent increase in global energy prices could result in increased restrictions in the 2022 southern hemisphere winter season, as a result of Argentina's budget constraints to acquire liquefied natural gas to cover for local shortfalls.

For its San Nicolás facility, Ternium Argentina has a long-term natural gas transportation agreement with Transportadora de Gas del Norte S.A., or TGN, and a renewable one-year natural gas distribution agreement with Litoral Gas S.A., or Litoral Gas. TGN and Litoral Gas are companies in which San Faustin holds significant but non-controlling interests. For its other facilities Ternium Argentina’s natural gas transportation and distribution needs are covered by the corresponding regional distributors Camuzzi Gas Pampeana S.A., Metrogas S.A. and Naturgy BAN S.A. We consume approximately 5.3 million btu of purchased natural gas to produce one ton of crude steel in Argentina.

Other inputs. Ternium Brasil and Ternium Argentina have on-site oxygen, nitrogen and argon separation plants in order to extract these gases for use in the steelmaking process. Ternium Brasil’s separation plants are managed by a consortium formed by Air Liquide Brasil Ltda., AirSteel Ltda., White Martins Gases Industriais Ltda., White Martins Steel Ltda. and ThyssenKrupp MinEnergy GmbH under a long-term contract for the supply of air, oxygen, nitrogen and argon. Ternium Argentina’s separation plants are managed by Air Liquide Argentina S.A. under a long-term contract for the supply of oxygen, nitrogen and argon.

Colombia

In Colombia, Ternium’s manufacturing of finished steel products relies on three sources: (a) the production of steel in its steelmaking facilities, which are based on the electric arc furnace technology; (b) the purchase of steel billets to be processed in its steel bar and coil mill; and (c) the purchase of steel products, both from our overseas subsidiaries and from third parties. The electric arc furnace technology melts steel scrap to produce steel billets, which are then rolled into various long products. Ternium’s production process requires extensive use of electricity. Steel products are the largest component of production costs; scrap and electricity costs are also significant.

Semi-finished and finished steel products. Ternium’s operations in Colombia include non-integrated facilities that process steel supplied by Ternium’s overseas subsidiaries and semi-finished and finished steel purchased from third-party suppliers procured in the domestic and international markets. We purchased from third parties approximately 485,000 tons of semi-finished and finished steel products in 2021, 283,000 tons in 2020 and 299,000 tons in 2019.

Steel scrap. Scrap is the main raw material for producing steel in our steelmaking facilities in Colombia. Ternium sources 100% of its steel scrap needs from the local scrap market. We consume approximately 1.1 tons of scrap to produce one ton of crude steel in Colombia.

56

Electricity. Manizales is our main electricity consuming unit in Colombia, mainly due to its electric arc furnace-based steel production operations. Manizales purchases electricity from Isagen S.A. E.S.P., a Colombian power company, under a supply contract expiring in December 2028. The electricity price is based on a fixed rate adjusted by the wholesale price index. We consume approximately 0.4 MWH of electricity to produce one ton of crude steel in Colombia.

Product Quality Standards

Ternium develops its products and services with a philosophy of continuous improvement and seeks to excel in its internal quality control of its products and processes. Ternium’s products are manufactured in accordance with proprietary standards and the requirements of customers, and within the specifications of recognized international standardization entities including the International Organization for Standardization, or ISO, the American Society for Testing and Materials, the European Standards, the Japanese Industrial Standards, the Society of Automotive Engineers, and the standards of the American Petroleum Institute. Ternium also has product certifications based on international or local standards depending on the markets served.

Ternium established and implemented a Quality Management System, or QMS, and continuously improves its effectiveness in compliance with the requirements of the applicable ISO 9001:2015 and IATF 16949:2016, intended for production of automotive supplies, and other specific requirements. Ternium’s QMS operates with aligned strategies, objectives and criteria throughout Ternium’s subsidiaries. To keep its ISO multisite certification, the QMS is audited annually by Lloyd’s Register Quality Assurance.

Ternium Mexico’s, Ternium Brasil's and Ternium Argentina’s metallurgical testing laboratories are accredited for the performance of various relevant technical tests in accordance with ISO/IEC 17025:2017 General Requirements for the Competence of Testing and Calibration Laboratories or equivalent standards.

In 2021, Ternium continued improving its Product Safety Management program in accordance with IATF 16949:2016, encompassing steel products incorporated at safety components of vehicles. This program aims at contributing to the automotive industry's goal of preventing massive product recall events.

Research and Development; Product Development

Ternium is developing a new product roadmap to increase its offering of resistant and lightweight steel products for diverse uses, and a new portfolio of coated products under a low carbon and green economy. Of note in this regard, the design parameters of the new state-of the-art hot-rolling mill in Pesquería, Mexico, meet the requirements for the development and production of innovative hot-rolled steel products as well as of substrates for high-end automotive galvanized exposed and structural products.

The company's research programs are developed in its own facilities and are complemented with its participation in a broad-based international network of industry consortia, universities and research laboratories.Ternium is a member of WorldAutoSteel, an organization comprising some of the world's major steel producers. Sponsored by worldsteel, the group develops solutions and provide design tools to the automotive industry,promoting the merit of advanced steels vis-à-vis alternative materials. Under this framework, Ternium participates in the Steel E-Motive project, which is developing the concept design of an autonomous and electric vehicle meant for the expected mobility requirements by the year 2030.

We have identified synergies in collaborating with Ternium’s customers in the early stages of their projects, as it enables to build close supplier-customer relationships, anticipate market requirements (such as USMCA compliance requirements) and plan new production processes. In this regard, in the year 2021 Ternium's subsidiary in Argentina was recognized for the development of high-strength advanced steel for use in the chassis of pick-ups. Likewise, the company is working on new metallurgical concepts for the next generation of automotive steel.

Ternium promotes the participation of students and university researchers in the early stages of its projects. This approach, which includes some of the most prestigious institutions of the public and private sectors, enable us to widen the research network and capabilities of the company, promoting the development of fundamental knowledge and know-how at the universities and optimizing Ternium's in-house research resources. The goal is to design and develop solutions to obtain a better and more sustainable steel. These activities gradually restarted during the year 2021, after being affected by restrictions related to the COVID-19 outbreak in 2020.

57

In 2021, Ternium inaugurated a new research and development center in Pesquería, Mexico. This new facility incorporated new equipment and capabilities to test steel products performance for automotive, home appliance and other industrial customers. The new research and development center will enable Ternium to speed up the development of new high-end steel products to be processed at recently inaugurated facilities in its industrial center in Pesquería.

In addition, the company incorporated to its research infrastructure a new pilot facility for the coal coking process. With this new plant, the company was able to develop new coal blends based on scale tests, which resulted in an increased flexibility in the purchasing of diverse coal qualities in a context of high volatility in the price and availability of raw materials in the international markets. Likewise, the company advanced studies, on a pilot plant scale, related to the use of biomass in the blast furnace. These studies are aimed at reducing carbon dioxide emissions, one of the initiatives under Ternium's climate change strategy.

Regulations

Environmental, Social and Governance Regulations

We are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees relating to environmental, social and governance matters, including laws and regulations relating to climate-change mitigation, use of resources, hazardous materials and radioactive materials, and air emissions, water discharges and waste management; legislation on human rights and modern slavery; human capital, including equal opportunity, gender and disabilities equality, working conditions, work-life balance, and labor market access; and applicable rules on internal control and risk management, anti-corruption, business partner relationship management and other governance issues.

ESG regulation has been evolving over the past years and is expected to continue to evolve in the future, particularly with respect to environmental matters. The ultimate impact of complying with ESG regulations, in particular with applicable environmental regulation, is not always clearly known or determinable because certain laws and regulations have been evolving in the past years or are under constant review by competent authorities.

In response to an increasing investor focus and reliance on climate and ESG-related disclosure and investment, the U.S. Securities and Exchange Commission (“SEC”) announced in March 2021 the creation of a Climate and ESG Task Force to identify ESG-related misconduct and potential violations. In addition, the SEC included, as one of its 2021 examination priorities, a greater focus on climate and ESG-related risks. In March 2022, the SEC proposed rule changes that would require registrants to include certain climate-related disclosure in their periodic reports, including information about climate-related risks that are reasonably likely to have a material impact on their business, results of operations, or financial condition, and certain climate-related financial statement metrics in a note to their audited financial statements.

Laws and regulations protecting the environment have become increasingly complex and more stringent and expensive to implement in recent years. Environmental requirements vary from one jurisdiction to another adding complexity to the operations of global companies, such as Ternium. Ternium’s corporate environmental and energy policy commits each of its business units to comply with applicable environmental laws and regulations, and aims to achieve the highest standards of environmental performance as a basis to enhance sustainable development. Compliance with environmental laws and regulations, and monitoring regulatory changes, is addressed primarily at a regional level.

The expenditures necessary to remain in compliance with environmental laws and regulations, including site or other remediation costs, or costs incurred from potential environmental liabilities, could have a material adverse effect on our financial condition and profitability. While we incur and will continue to incur expenditures to comply with applicable laws and regulations, there always remains a risk that environmental incidents or accidents may occur that may negatively affect our reputation or our operations.

For more information on the impact of climate change legislations and increasing regulatory requirements, see Item 3.D. “Key Information – Risk Factors - Certain Regulatory Risks and Litigation Risks – The cost of complying with environmental regulations and potential environmental ad product liabilities may increase Ternium's operating costs and negatively impact Ternium's business, financial condition, results of operation and prospects;” and Item 3.D. “Key Information – Risk Factors - Certain Regulatory Risks and Litigation Risks – Climate change legislation and increasing climate regulatory requirements aimed at transitioning to a lower-carbon economy could result in unexpected capital expenditures and costs, negatively affect our competitiveness, reducing our market share and results of operations, and hampering our ability to access adequate financial resources.”

Below is a summary of relevant environmental legislation applicable to Ternium.

58

Mexico:

Mexican environmental laws establish the “polluter pays” principle, pursuant to which the individual that causes an environmental breach is responsible for restoring the environment to its pre-pollution condition and face economic and, in some cases, criminal liabilities. Mexican regulations also establish an annual report scheme of GHG emissions.

In addition, Mexican regulations provide for carbon dioxide emission taxes through taxes on fuels, with rates reviewed annually, depending on their efficiency in terms of carbon dioxide emission per unit of energy obtained. The carbon dioxide emission tax for natural gas is currently zero. Mexico has also started a pilot trade market for carbon dioxide emissions. Ternium Mexico is a large consumer of natural gas. For further information see “—Raw Materials, Slabs, Energy and Other Inputs.”

Brazil:

The Company’s activities are subject to wide-ranging Brazilian environmental legislation at the federal, state and municipal levels that govern, among other aspects, effluents, atmospheric emissions and the handling and final disposal of hazardous waste, as well as the obligation to obtain operating licenses for the installation and operation of potentially polluting activities.

Brazilian environmental legislation imposes criminal and administrative penalties on natural persons and legal entities that commit environmental crimes or infractions, as well as for the obligation to repair the environmental damage caused. Environmental crimes or infractions could subject the Company to penalties that include:

·    fines that at the administrative level could reach as high as BRL50 million, depending on the violator’s economic capacity and past record, as well as the severity of the facts and prior history, with the amounts potentially doubled or tripled in the case of repeat offenders;

·    suspension of or interference in the activities of the respective enterprise; and

·    loss of benefits, such as the suspension of government financing and the inability to qualify for public bidding processes and tax breaks.

In addition, strict liability is applicable to environmental crimes for both natural persons and legal entities. Environmental legislation also provides for disregarding the legal status of a company’s controlling shareholders whenever such status represents an impediment to receiving restitution for environmental damages.

In the civil sphere, environmental damage results in joint and several liability as well as strict liability. This means that the obligation to repair the environmental damage may affect all those directly or indirectly involved, regardless of any proof of who is to blame. As a result, the hiring of third parties to intervene in its operations to perform such services as final disposal of solid waste does not exempt the Company from liability for any environmental damage that may occur.

Argentina:

Argentine environmental laws and regulations require the renewal of environmental licenses and emission permits every two or four years, depending on the activity. Although such renewals may take longer than expected and the renewal process may extend beyond the due date of the then current licenses and permits, no shut down orders against the Company have ever been issued while the renewal processes are ongoing. In addition, Argentine environmental laws and regulations require mandatory environmental insurance to cover facilities that use hazardous materials.

Argentine legislation provides for mandatory minimum shares of renewable energy in total electricity consumption. For further information see “—Raw Materials, Slabs, Energy and Other Inputs—Brazil and Argentina—Electricity”.

In addition, Argentine law provides for a carbon dioxide emission tax. Natural gas is excluded from such tax, and metallurgical coal and petrochemical coke are exempted as long as they are used as part of an industrial process, other than for energy generation. For additional information regarding how carbon taxes affect our operations in Argentina, see Item 3. “Key Information—D. Risk Factors—Certain Regulatory Risks And Litigation Risks—Climate change legislation and increasing climate regulatory requirements aimed at transitioning to a lower-carbon economy could result in unexpected capital expenditures and costs, negatively affect the Company's competitiveness, reducing its market share and results of operations, and hampering its ability to access adequate financial resources.”

Mining regulations in Mexico

Because our operations in Mexico include mining, we are also subject to Mexican regulations relating to mining and mining concessions. Under Mexican law, mineral resources belong to the Mexican nation and a concession from the Mexican federal government is required to explore for or exploit mineral reserves. Pursuant to Mexico’s Mining Law, mining concessions may only be granted to Mexican individuals and to legal entities incorporated under Mexican law. Foreign investors may hold up to 100% of the shares of such entities.

A mining concession allows its holder to perform both exploration works (including identifying mineral deposits and quantifying and evaluating economically minable reserves) and exploitation works (including detaching and extracting mineral products from such deposits). Mining concessions are granted for a 50-year period from the date of their recording in the Public Mining Registry; following the expiration of the initial concession term, the concessions are renewable for an additional 50-year term in accordance with, and subject to, the procedures set forth in the Mining Law.

Mining concessions grant several specified rights to the concessionaire, including:

•the right to dispose freely of mineral products obtained as a result of the exploitation of the concession;

•the right to obtain the expropriation of, or an easement with respect to, the land where the exploration or exploitation will be conducted; and

•the use of water in the mine to facilitate extraction.

In addition, a holder of a mining concession is obligated, among other things, to explore or exploit the relevant concession (including the achievement of minimum investment targets), to pay for any relevant mining rights, to comply with all environmental and safety standards, and to provide information to and permit inspections by the Secretariat of Economy. Mining concessions may be terminated if the obligations of the concessionaire are not satisfied.

A company that holds a concession must be registered with the Public Mining Registry. In addition, mining concessions and permits, assignments, transfers and encumbrances must be recorded with the Public Mining Registry to be enforceable. We believe that our material mining concessions are duly registered in the Public Mining Registry.

For information regarding amendments to the Mining Law and regulations in Mexico, see Item 3. “Key Information—D. Risk Factors—Risks Relating to Ternium's Mining Activities—Required governmental concessions could be subject to changes or termination, permits and rights of use and occupancy could be difficult to obtain or maintain and taxes or royalties applicable to the mining industry could increase, all of which could adversely affect Ternium's mining activities and operating costs.”

Trade regulations

Intense global competition in the steel industry lead many countries, from time to time, to increase duties or impose restrictions on steel product imports to protect their domestic industries from trades that are not made under market conditions or that are otherwise unfair. Such measures protect domestic industries from increased imports sold at dumped or subsidized prices. Mexico, Colombia and the United States, among other countries, have several trade remedy measures in place. In addition to antidumping and countervailing measures, in 2018 the United States imposed, under Section 232 of the Trade Expansion Act of 1962, a 25% tariff on steel imports; however, Australia, Canada and Mexico are exempted from the tariff (though subject to a continuous monitoring system of their trade flows). Although Argentina, Brazil and South Korea were also exempted from the measure, they were subject to quota system agreements covering steel imports from those countries. In the case of the European Union, the U.S. has recently shifted the 25% tariff to a Tariff Rate Quota (TRQ) system for steel products melted and poured in this region, and Japan and the United Kingdom will enter into a similar system in April and June 2022, respectively.

Bilateral or regional free trade agreements have liberalized trade among some countries, providing for reduced or zero tariffs for many goods, including steel products. The entry into force of various free trade agreements and certain countries’ imposition of trade remedy measures can and have both benefited and adversely affected Ternium’s home markets and export sales of steel products, as described below. For further information, see also Item 3. “Key Information—D. Risk Factors—Certain Regulatory Risks and Litigation Risks—International trade actions or regulations and trade-related legal proceedings could adversely affect Ternium’s sales, revenues and overall business.” Relevant free trade agreements and trade remedy measures, by country, are described below:

Mexico

Imports of steel products to Mexico:

The Mexican government has imposed certain antidumping measures on imports of steel products that are similar to the ones produced by Ternium Mexico. The following is a description of measures currently in effect and ongoing investigations:

•Slabs: On September 21, 2020, the Mexican government initiated an antidumping investigation on imports of steel slabs from Brazil and Russia. On November 4, 2021, the Mexican authorities finalized the investigation, finding that Ternium Brazil did not dump slabs into Mexico, and that the antidumping petition lacked sufficient industry support, therefore the investigation was concluded without imposing any antidumping duties.

•Hot-rolled products: On March 28, 2000, the Mexican government imposed antidumping duties on the Russian Federation and Ukraine of 30.31% and 46.66%, respectively, on hot-rolled products. The measure has been extended four times for five years each, on March 17, 2006; on September 8, 2011 (modifying the duties to 21% and 25% for Russia and Ukraine respectively); on January 28, 2016 and on March 23, 2021. On July 19, 2013, the Mexican government initiated an anti-circumvention investigation on imports of boron-alloyed hot-rolled products from Russia. On March 21, 2014, Mexico’s Secretariat of Economy published the final determination on the investigation, by which boron-alloyed hot-rolled products from Russia are now subject to a 21% antidumping duty. Furthermore, on December 22, 2015, the Mexican government published the final antidumping determination imposing definitive and specific antidumping duties on China ($354.92 per ton, except for imports from Tangshan Iron and Steel Group Company Limited, which were fixed in $335.60 per ton), Germany ($166.01 per ton, except for imports from ArcelorMittal Bremen GmbH, which were fixed in $137 per ton) and France ($75.59 per ton, except for imports from ArcelorMittal Mediterranée S.A.S., which were fixed in $67.54 per ton), on hot-rolled products. This measure is undergoing a sunset review.

•Plate in coils: Since June 1996, an antidumping duty of 29.3% has been in place on imports from Russia. The measure has been extended four times, in June 2003, June 2007, November 2012 and May 2017. On July 5, 2013, the Mexican government initiated an anti-circumvention investigation on imports of boron-alloyed plate in coil imports from Russia. On February 19, 2014, Mexico’s Secretariat of Economy published the final determination on the investigation by which boron-alloyed plate in coil imports are now subject to a 29.3% antidumping duty. On May 27, 2021, the Mexican government initiated a sunset review of the measure, which is currently ongoing.

•Cold-rolled products: In June 1999, Mexico imposed antidumping duties on cold-rolled steel sheets from the Russian Federation and Kazakhstan of 15% and 22% respectively. The measure has been extended four times, in December 2005, December 2010, July 2015, and August 2020. In addition, on October 1, 2012, the Mexican government initiated an antidumping investigation on cold-rolled steel imports from South Korea. On December 26, 2013, Mexico’s Secretariat of Economy published a suspension agreement under which Korean exporters, Posco and Hyundai Hysco Company Limited, or Hyundai, voluntarily undertook to limit their cold-rolled products exports to the Mexican market. On May 25, 2016, the Mexican authorities initiated a change of circumstances review of this suspension agreement, and on June 13, 2017, the Secretariat of Economy issued a final determination increasing Posco’s and Hyundai’s quotas for 2017 and 2018. On August 23, 2018, the Mexican government initiated a sunset review of the agreement and issued a final affirmative determination on November 1, 2019. On May 14, 2019, Mexico initiated a second change of circumstances review of the suspension agreement for Posco and on November 5, 2020, a final determination was issued increasing Posco's quota for the years 2019 to 2023. Furthermore, on June 19, 2015, Mexico imposed antidumping duties on cold-rolled steel products from China between 65.99% and 103.41%, with rates depending on the Chinese exporting company. This measure is undergoing a sunset review. On December 2015, Mexico initiated a circumvention inquiry against cold rolled steel products with boron added from China. On July 11, 2016, the Mexican government issued a final determination confirming China’s circumvention practice and thus, extending the antidumping duties. On August 16, 2021, under the latest sunset review, this measure was extended until June 2025.

•Coated flat products: On December 17, 2015, the Mexican government initiated an antidumping investigation on coated flat products from China and Taiwan. On July 29, 2016, Mexico issued a preliminary determination imposing provisional antidumping duties on Chinese exports of between $192 and $438 per ton, and of $563 per ton on Taiwanese products. On June 5, 2017, Mexico issued a final determination imposing antidumping duties on Chinese exports of between 22.22% and 76.33%, and of between 22.26% and 52.57% on Taiwanese products. On November 21, 2017, Mexico amended its final determination imposing antidumping duties applicable to products sold by Chinese companies, one of which was imposed duties for $187 per ton, while others face duties ranging between 22.26% and 76.33% of the products’ price. On August 30, 2021, Mexico initiated an antidumping investigation on coated flat products imports from Vietnam.

61

•Reinforcing bars: Since 1995, imports of reinforcing bars from Brazil are subject to an antidumping duty of 57.69%. Subsequent sunset reviews determined the continuation of the antidumping duty for additional five-year periods. On December 23, 2021, under the latest sunset review, this measure was extended until August 2025.

•Wire rod: Since September 2000, imports of wire rod from Ukraine are subject to an antidumping duty. The initial antidumping margin was 30.52%. In June 2006, the first sunset review resolution determined the continuation of the antidumping duty for five more years. On September 7, 2010, a second sunset review was initiated, and on March 7, 2012, the Mexican government increased the antidumping duty to 41% until September 2015. The Mexican government initiated the third sunset review on September 4, 2015, and extended the measures for an additional five-year period on September 2, 2016. On Dec. 10, 2021, under the latest sunset review, this measure was extended until September 2025. In addition, on September 2, 2015, the Mexican government initiated an antidumping investigation on wire rod from China. On July 28, 2016 the Mexican government imposed a specific antidumping duty of US$0.49 per kilogram for five years. The Mexican government initiated a sunset review of the measure on July 22, 2021.

•Welded Tubes: On December 7, 2016, the Mexican government initiated an antidumping investigation on welded tubes of circular, square or rectangular cross section from China. On March 8, 2018, Mexico imposed final antidumping duties on Chinese exports of between $356 and $618 per ton.

On October 7, 2015, the Mexican Government issued a decree imposing a temporary 15% import tariff on steel products other than semi-finished products, including plate, hot-rolled, cold-rolled, coated, tubular, structural and wire rod, applicable to imports from countries with whom Mexico had no trade agreement in place. According to the latest tariff schedule published by the Mexican Government on November 22, 2021, the import tariff of most products will be reduced to 10% from June 30, 2022 (and further reduced to 5% from September 22, 2023, and lifted on October 1, 2024) with the exception of certain products that have different tariff reduction schedules (such as two-size zinc plated steel sheets and some seamless pipe products, towers and lattice masts).

Exports of steel products from Mexico:

U.S. authorities have imposed a number of measures on steel import products from Mexico, thereby restricting Ternium’s exports to the U.S. The following is a description of measures currently in effect and ongoing investigations:

•Carbon and alloy steel wire rod: Ternium Mexico's wire rod exports are subject to an antidumping duty of 9.54% pursuant to the latest administrative review on the antidumping duty order on carbon and certain alloy steel wire rod. On August 27, 2020, as a result of the most recent sunset review, such duty was extended for five more years.

•Pipe and tube: During 2007, U.S. authorities initiated an antidumping investigation of light-walled rectangular pipe and tube, or LWRPT, from, among other countries, Mexico. On June 13, 2008, the authorities made a final determination of sales at less than fair value in the investigation of LWRPT from Mexico and, consequently, imposed antidumping duties. On February 18, 2011, the authorities published the final results of the first administrative review by which Mexican LWRPT exports were subject to an antidumping duty of 6.13% until May 23, 2014, when U.S. authorities made a final affirmative sunset review of 2.40% for Maquilacero and 3.76% for certain other companies subject to the review, including Ternium Mexico. On March 12, 2018, U.S. authorities published the final results of the 2015-2016 administrative review, which did not impose any antidumping duties on Prolamsa and Aceros Cuatro Caminos S.A. de C.V., but imposed an antidumping duty of 3.76% on other exporters. On April 22, 2019, the U.S. authorities imposed a duty range of between 8.32% and 17.65% for certain Mexican producers or exporters as a result of the 2016-2017 administrative review. As a result of the 2017-2018 review, Ternium Mexico’s current margin is 3.17%. On August 4, 2020, as a result of the most recent sunset review, such duty was extended for five more years. On August 10, 2015, U.S. authorities initiated an antidumping investigation on imports of heavy-walled rectangular pipe and tube, or HWRPT, from Korea, Turkey and Mexico. On September 13, 2016 the authorities issued an antidumping duty order on imports of HWRPT, imposing an antidumping duty range of between 2.34% and 3.82% for Korea, 17.83% and 35.66% for Turkey, and in the case of Mexico 3.83% for Maquilacero, 5.21% for Productos y Laminados de Monterrey and 4.91% for Ternium Mexico and others. On July 10, 2019, the U.S. authorities issued the final results of the 2016-2017 administrative review imposing duties of 1.43%, 8.09% and 6.13% on Maquilacero, Prolamsa and other exporters including Ternium, respectively. On July 13, 2020, U.S. authorities issued the final results of the 2017-2018 administrative review imposing duties of 4.89%, 7.47% and 4.91% on Maquilacero, Prolamsa and other exporters, respectively; Ternium Mexico’s current margin per the 2018-2019 administrative review is 0%.

•Welded pipes: Since 1992, pursuant to an antidumping duty order on circular welded non-alloy steel pipe -or standard pipe- from various countries, including Mexico, standard pipes manufactured by Hylsamex and Grupo

62

Imsa were subject to antidumping duties. In 2007, such measures were extended for five more years. In August 2009, U.S. authorities published the final results of a changed circumstances review, concluding that Ternium Mexico is the successor-in-interest to Hylsamex for purposes of determining antidumping duty liability. In accordance with the latest administrative review, the applicable duty for Ternium Mexico is 24.17%. The measure has since been extended two more times, in 2012 and February 2018.

•Reinforced bars: On November 6, 2014, U.S. authorities made a final determination on reinforced bar imports from Mexico, imposing antidumping duties between 20.58% and 66.70%. As a result of the 2016-2017 administrative review, the U.S. Government imposed a duty of 3.65% on Mexican producers, including Ternium Mexico. As a result of the 2016-2017 administrative review, the U.S. Government imposed duties of 7.12% for Deacero, 1.46% for Grupo Simec and 5.54% for other Mexican producers, including Ternium Mexico. The measure was renewed on October 22, 2020 for five more years.

Trade agreements:

Mexico has signed trade agreements with several countries or trade blocs aimed at liberalizing trade between them:

NAFTA was signed among Canada, Mexico and the United States and came into effect on January 1, 1994. NAFTA provided for the progressive elimination over a 10-year period of duties on, among other things, steel products traded between or among Mexico, the United States and Canada. As a result, zero tariffs applied to steel products traded within NAFTA countries, with the exception of the application of the above-mentioned imposition of a 25% tariff on steel imports under Section 232 of the Trade Expansion Act of 1962 to Mexico and Canada during 2018 and 2019. During 2019, Mexico and the United States agreed to waive such tariff, subject to an agreed premise of continuous monitoring for surges in steel imports and transshipment of non-NAFTA material into the United States. NAFTA was subsequently replaced by the United States-Mexico-Canada Agreement, or USMCA, which became effective in July 2020. The United States, Mexico and Canada agreed to modify the definition of "North American steel" (with such amendment becoming effective in July 2027), for purposes of vehicles being awarded preferential treatment under USMCA, restricting the defined term to steel melted and poured within the three countries.

The Mexican-European Free Trade Agreement, or MEFTA, became effective on July 1, 2000. MEFTA provided for the phase-out and eventual elimination of Mexican and European duties on all industrial goods, including finished steel products. The European Union eliminated all import duties on Mexican industrial goods, including finished steel products, as of January 1, 2003, while Mexico eliminated all import duties on European industrial goods, including finished steel products, as of January 1, 2007. During April 2018, the European Union and Mexico concluded negotiations to bring the MEFTA up to date. The amended agreement, which has not yet come into force, does not provide for changes in steel trade conditions. Following BREXIT, Mexico and the UK reached a Trade Continuation Agreement, published in June 1, 2021, effective retroactively from January 1, 2021.

The Economic Partnership Agreement between Japan and Mexico came into force on April 1, 2015. The new agreement provides for a phase-out and eventual elimination of Mexican and Japanese duties on all industrial goods within a ten-year period. Beginning on April 1, 2015, all duties on steel products were eliminated. Until March 31, 2015, an import duty of 3% was applicable to Japanese steel imports.

Mexico and Argentina signed an Economic Complementation Agreement, known as ACE 6 for its initials in Spanish, in November 2003, whereby reciprocal tariff preferences are currently granted. In 2006, Mexico and Argentina modified the ACE 6 Agreement, reducing to zero import duties on imports of certain steel products from the other country. Zero import duties included exports from Mexico to Argentina and vice versa for up to 90,000 tons per year of slabs, 60,000 tons per year of cold rolled coils and 30,000 tons per year of corrosion resistant coils, including hot dip galvanized and pre-painted sheets.

The Comprehensive and Progressive Agreement for Trans-Pacific Partnership, or CPTPP, was signed by Mexico together with Australia, Brunei, Canada, Chile, Japan, Malaysia, New Zealand, Peru, Singapore and Vietnam, becoming effective in December 2018.

Mexico has entered into trade agreements with Colombia, Japan, Chile, Bolivia, Nicaragua, Costa Rica, Uruguay and the European Free Trade Association, an intergovernmental organization set up by Liechtenstein, Norway, Iceland and Switzerland among others.

Argentina

Imports of steel products to Argentina:

63

In the past, the Argentine government imposed various antidumping measures on imports of certain flat steel products that compete directly with Ternium’s sales in Argentina. After several subsequent revisions of such cases, there are currently no measures in place.

Trade agreements:

Argentina has signed free trade agreements with several countries or trade blocs aimed at liberalizing trade between them, including the following:

In early 1991, Argentina entered, together with Brazil, Uruguay and Paraguay, into the Treaty of Asunción, creating the Mercado Común del Sur (Southern Common Market, or "Mercosur"), a common market organization that aimed to bring about the free movement of goods, capital, services and people among its member states. In 2004, the Mercosur members entered into the Protocol of Ouro Preto, creating a customs union among them. On January 1, 2013, Venezuela became a full member of Mercosur but was suspended in December 2016. Over time, Mercosur has eliminated or significantly reduced import duties, tariffs and other trade barriers among member states. Since January 1, 2000, zero tariffs apply to steel products traded among them.

Applicable steel import tariffs to Mercosur member countries from non-member countries currently range between 2% and 16%. However, every six months, Mercosur members may exempt from tariffs a limited number of products imported from non-member countries. Uruguay has elected to exempt certain steel products, including cold-rolled sheets and galvanized flat steel products. This exemption regime is expected to be in force until December 31, 2022, but has been extended in the past and, if agreed by Mercosur member countries, could again be extended in the future.

In 2004, Mercosur and the Comunidad Andina de Naciones (Andean Community, or "CAN"), currently including Bolivia, Colombia, Ecuador and Peru, signed a free trade agreement aimed at reducing and eventually eliminating tariffs on steel products traded among member countries. While all tariffs on steel products traded between Argentina and Bolivia and between Argentina and Peru have been eliminated, the elimination of tariffs on steel products traded between Argentina and Ecuador and Argentina and Colombia are subject to a pending agreement on rules of origin specifications. Mercosur entered into a trade agreement with Chile in 2005. As a result, all tariffs on steel products traded between Mercosur and Chile have been eliminated. In addition, Mercosur is negotiating a free trade agreement with the European Union. On June 28, 2019, the parties reached an agreement in principle that is not yet effective.

In November 2003, Argentina and Mexico signed the ACE 6. For further information, see “—Regulations—Trade Regulations—Mexico.”

Colombia

Imports of steel products to Colombia:

The Colombian government has imposed certain antidumping and safeguard measures on imports of steel products. The following antidumping measures are currently in effect:

•Low-carbon wire rods: On October 8, 2013, the Colombian government imposed provisional safeguard duties of 21.29% on imports of low-carbon wire rods from countries belonging to the World Trade Organization (WTO), with the exception of Cuba, Ecuador, the United States and Venezuela. On April 30, 2014, Colombia imposed final safeguard duties of 21.29% on imports of low-carbon wire rod from WTO members with the exception of Argentina, Chile, Ecuador, Costa Rica, the United States and Canada, to remain in force for a period of one year that ended on March 31, 2015. On October 2015, the Colombian government imposed provisional antidumping duties on imports of low-carbon wire rod from China, consisting on a duty calculated based on a price of $541.06 per ton less the actual FOB import price for such product, in force until the end of March 2016. On May 11, 2016, Colombia imposed final antidumping duties of $419 per ton less the actual FOB import price, for a five-year period. In June 2021, under a sunset review, the duty was terminated.

•Steel “L” and “U” profiles: On August 24, 2018, the Colombian government imposed provisional antidumping duties on imports of steel “L” and “U” profiles from China, consisting on a duty calculated based on a price of $473.28 per ton less the actual FOB import price for such product, for a two-year period. This measure is undergoing a sunset review. In May 2021, under a sunset review, the duty was terminated.

•Galvanized flat steel products: On March 5, 2014, Colombia imposed final antidumping measures on imports of galvanized flat steel products from China, to remain in force for a period of three years, consisting of a duty calculated based on a price of $824.57 per ton less the actual FOB import price for such product. On December 19,

64

2017, Colombia renewed the antidumping measure for a period of three years, changing the duty to 47.62%. this measure is undergoing a sunset review. In July 2021, under a sunset review, the duty was terminated.

•Steel profiles for drywall: On September 1, 2020, the Colombian government initiated a dumping investigation on imports of steel profiles for drywall from China. On December 2, 2020, the preliminary determination was issued without imposition of provisional duties. On October 29, 2021, the Colombian government imposed final antidumping duties of 37.88%, for a three-year period, starting November 3, 2021.

On March 13, 2019, the Colombian government imposed a temporary 8.5% import tariff on steel reinforced bars for a period of two years, which expired in March 2021.

Trade agreements:

Most steel imports to Colombia from countries with whom Colombia does not have a free trade agreement in place, are subject to import tariffs of between 5% and 10%.

Colombia has entered into free trade agreements with several countries or trade blocs aimed at liberalizing trade between them.

CAN is a trading bloc, currently including Bolivia, Colombia, Ecuador and Peru, established during 1993 and approved in 1994 for the purpose of promoting trade relations among its members and between CAN and the rest of the world. The treaty formalized a customs union among CAN’s member states. Over time, CAN has eliminated or significantly reduced import duties, tariffs and other trade barriers among member states. In particular, zero tariffs have applied to steel products imported from other member states since January 1, 2000. CAN and Mercosur have signed a free trade agreement. For further information, see “—Regulations—Trade Regulations—Argentina.”

During June 1994, Colombia and Mexico signed a free trade agreement. For further information on this agreement see “—Regulations—Trade Regulations—Mexico.”

On August 9, 2007, Colombia, El Salvador, Guatemala and Honduras established the Triángulo Norte (North Triangle), or TN, free trade agreement. Members of the TN signed multilateral agreements related to funds transfers and local and most favored nation statuses, and signed bilateral agreements aimed at reducing trade duties. Colombia’s free trade agreement with Guatemala started on November 12, 2009; with El Salvador on February 1, 2010; and with Honduras on March 27, 2010. Under TN, zero tariffs apply to several steel products imported from other member states.

Colombia’s free trade agreement with the United States became effective in October 2011. Under this agreement, steel import tariffs from Colombia to the United States will remain at 0% and steel import tariffs from the United States to Colombia will decrease from a range of between 5% and 10% in 2011 to 0% in one, five or 10 years according to the product category. In particular, wire rods import tariffs became 0% beginning in 2012 and rebar import tariffs decreased gradually, reaching 0% in 2021. On March 8, 2018, the U.S. president imposed a 25% tariff on steel imports, in force since March 23, 2018. See Item 4. “Information on the Company—B. Business Overview—Regulations—Trade Regulations—United States.”

In addition, Colombia has signed free trade agreements with Chile, Canada, Costa Rica, the European Union, South Korea and Israel, in effect since May 2009, August 2011, August 2016, August 2013, July 2016 and August 2020, respectively, and has signed free trade agreements with Panama and the U.K., which are not yet effective. Colombia is currently negotiating free trade agreements with Japan and Turkey.

United States

U.S. authorities have imposed a number of measures on steel import products. Below is a description of measures currently in effect and ongoing investigations:

Imports of steel products to the United States:

•Hot-rolled products: On July 1999, the U.S. authorities imposed antidumping duties on hot-rolled products from Russia, currently of up to 184.56%. During October 2016, the measure was extended for five more years. The measure is currently under a sunset review. During November 2001, the U.S. government imposed antidumping and countervailing duties on certain hot-rolled carbon steel flat products from China, India, Taiwan, Thailand, Russia, Indonesia and Ukraine. Current antidumping duties range between 12.34% and 90.83% for China, 36.53% and 44.40% for India, 47.86% for Indonesia, 20.28% and 29.14% for Taiwan, 4.41% and 20.30% for Thailand and

65

90.33% for Ukraine, with rates depending on the exporting company. Current countervailing duties range between 336.62% and 360.23% for India and are set at 10.21% for Indonesia and 2.38% for Thailand. These measures were last confirmed in August 27, 2019. In addition, on September 24, 2015, the U.S. government initiated antidumping and countervailing investigations on hot-rolled products from Australia, Brazil, Japan, Korea, the Netherlands, Turkey and the United Kingdom. On October 3, 2016, the government issued antidumping and countervailing duty orders for a five-year period. Antidumping duties were imposed at the following rates: 29.58% for Australia; between 33.14% and 34.28% for Brazil; between 4.99% and 7.51% for Japan; between 4.61% and 9.49% for Korea; 3.73% for the Netherlands; between 4.15% and 6.77% for Turkey; and 33.06% for the United Kingdom. Countervailing duties were imposed on imports as follows: between 29.07% and 30.51% for Brazil; and between 0% and 9.49% for Korea. The measures are currently under sunset reviews.

•Cold-rolled products: On July 14, 2016, the U.S. government imposed antidumping duties on cold-rolled steel products, of 265.79% for China and 71.35% for Japan, and countervailing duties of 256.44% for China. On September 20, 2016, the U.S. government imposed countervailing duties on cold-rolled steel products of between 11.09% and 11.31% from Brazil, 10% from India and between 3.89% and 59.72% from Korea. In addition, on September 20, 2016, the U.S. government imposed antidumping duties on cold-rolled products of between 19.58% and 35.43% from Brazil, 6.78% from India, 7.60% from Korea, and between 5.40% and 25.17% from the United Kingdom. Following affirmative circumvention determinations on imports from Vietnam, the U.S. government imposed the same measures imposed on Chinese imports, and in December 2019 the same measures imposed on Korean imports. The measures are currently under sunset review.

•Corrosion-resistant flat products: On July 25, 2016, the U.S. government imposed countervailing duties on corrosion-resistant flat products of 39.05% to 241.07% on imports from China, of 8% to 29.49% on imports from India, of a de minimis to 38.51% on imports from Italy, and of a de minimis to 1.19% on imports from Korea. In addition, on July 25, 2016, the U.S. government imposed antidumping duties on corrosion-resistant flat products of 209.97% from China, between 3.05% and 4.43% from India, 12.63% and 92.12% from Italy, 8.75% and 47.80% from Korea, and 10.34% from Taiwan. These measures were subject to many circumvention inquiries. Currently, imports of corrosion-resistant flat products from Costa Rica, Malaysia, Vietnam and the United Arab Emirates from Chinese hot-rolled coils and/or cold-rolled coils are subject to antidumping and countervailing duties; and imports of corrosion-resistant flat products from Vietnam with Korean and Taiwanese hot-rolled coils and/or cold-rolled coils are subject to antidumping and countervailing duties. The measures are currently under sunset review.

•Wire rod: On October 29, 2002, the United States imposed antidumping duties to wire rod imports from Brazil (from 74.35% to 94.73%), Indonesia (4.05%), Moldova (369.10%) and Trinidad and Tobago (11.40%), and countervailing duties to Brazilian wire rod imports of between 2.31% and 6.74%. These measures were renewed for five year on August 27, 2020. On January 8, 2015, the United States imposed antidumping duties (between 106.19% and 110.25%) and countervailing duties (between 178.46% and 193.31%) on wire rod from China, with rates depending on the exporting company. These measures were renewed on June 26, 2020. On January 24, 2018, the United States imposed antidumping duties on wire rod from Russia (between 436.80% and 756.93%), Belarus (280.02%) and the United Arab Emirates (84.10%). On March 14, 2018, the United States imposed antidumping duties on wire rod from South Africa (between 135.46% and 142.26%) and Ukraine (between 34.98% and 44.03%). On March 19, 2018, the U.S. Department of Commerce published its final antidumping and countervailing determinations on imports of wire rod from Italy (antidumping duties of between 12.41% and 18.89% and countervailing duties of between 4.16% and 44.18%), South Korea (antidumping duties of 41.10%), Spain (antidumping duties of between 11.08% and 32.64%), Turkey (antidumping duties of between 4.74% and 7.94% and countervailing duties of between 3.81% and 3.86%) and the United Kingdom (antidumping duties of 147.63%).

U.S. authorities have imposed a number of measures on steel product imports from Mexico, including carbon and alloy steel wire rod, pipe and tube, and welded pipes. For further information, see “—Regulations—Trade Regulations—Mexico.”

In April 2017, the U.S. government initiated an investigation under Section 232 of the U.S. Trade Expansion Act. The investigation analyzed the effects of imports of steel products on national security. Based on the result of such investigation and on the resulting Commerce Secretary recommendations, on March 8, 2018, the U.S. president imposed a 25% tariff on steel imports, which entered into force on March 23, 2018. However, the U.S. administration temporarily exempted imports from Argentina, Australia, Brazil, Canada, the European Union, Mexico and South Korea. Currently, Australia, Canada and Mexico are exempt from the tariff (though subject to a continuous monitoring system of their trade flows). Although Argentina, Brazil and South Korea were also exempted from the measure, they were subject to quota system agreements covering steel imports from those countries. In the case of the European Union, the U.S. has recently shifted the 25% tariff to a Tariff Rate Quota (TRQ) system for steel products melted and

66

poured in this region, and Japan and the United Kingdom will enter into a similar system in April and June 2022, respectively. Under the exclusion procedure, implemented by the United States authorities, Ternium has filed multiple exclusions requests; while earlier requests were denied, the U.S. Department of Commerce granted exclusions for 250,000 tons of cold-rolled material from several sources and 13,000 tons of galvanized coils from Guatemala.

Insurance

Our subsidiaries carry insurance policies covering accidental loss or physical damage to its property and equipment (including machinery breakdown and business interruption arising from an insured event), general liability (including third party, employer, product, sudden and accidental pollution and port liability) and other insurance, including marine cargo, construction all risk, life and workers’ compensation and automobile insurance. These insurance policies have coverage, limits and conditions, that we believe are customary in the steel products industry and in line with legal and domestic market requirements. Nevertheless, the limits, deductibles and/or self insured retentions of these insurance policies could not be sufficient to recover all losses suffered from such events. In addition, some particular events could not be covered under these insurance policies.

Disclosure Pursuant to Section 13(r) of the Exchange Act

The Iran Threat Reduction and Syria Human Rights Act of 2012, created a new subsection (r) in Section 13 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), which requires a reporting issuer to provide disclosure if the issuer or any of its affiliates knowingly engaged in certain enumerated activities relating to Iran, including activities involving the Government of Iran. Ternium did not engage in any Iran related activity during the year ended December 31, 2021. However, the Company is providing the following disclosure pursuant to Section 13(r) with respect to Iran related activity by its affiliates.

Tenaris

Tenaris is also controlled by San Faustin and, accordingly, it is deemed an “affiliate” of the Company, as such term is defined in Exchange Act Rule 12b-2. In response to our inquiry, Tenaris provided the disclosure included below.

In July 2015, the Islamic Republic of Iran entered into the Joint Comprehensive Plan of Action (“JCPOA”) with China, France, Germany, Russia, the United Kingdom and the United States, which resulted in the partial lifting in January 2016 of certain sanctions and restrictions against Iran, including most U.S. secondary sanctions against such country. On May 8, 2018, the United States announced that it would cease participation in the JCPOA and would begin re-imposing nuclear-related sanctions against Iran after a wind-down period. Following the U.S. withdrawal from the JCPOA, the European Union updated Council Regulation (EC) No. 2271/96 of 22 November 1996 (the “EU Blocking Statute”), to expand its scope to cover the re-imposed U.S. nuclear-related sanctions. The EU Blocking Statute aims to counteract the effects of the U.S. secondary sanctions.

Tenaris ceased all deliveries of products and services to Iran by the end of October 2018, that is, during the wind-down period and before the full reinstatement of U.S. secondary sanctions on November 5, 2018. Tenaris has not, directly or indirectly, delivered any goods or services to Iran or Iranian companies during 2021 and does not intend to explore any commercial opportunities in Iran, nor does it intend to participate in tender offers by, or issue offers to provide products or services to, Iranian companies or their subsidiaries.

As of December 31, 2021, Tenaris’s subsidiary, TGS maintains an open balance for an advance made by Toos Payvand Co. for approximately EUR 0.04 million (approximately $0.04 million) for goods that remained undelivered following the reinstatement of U.S. secondary sanctions.

All revenue and profit derived from Tenaris’s sales to Iran was recorded in the fiscal year in which such sales were performed and, therefore, no revenue and profit has been reported in connection with commercial activities related to Iran for the year ended December 31, 2021.

Tenaris has procedures in place designed to ensure that its activities comply with all applicable U.S. and other international export control and economic sanctions laws and regulations.

Other Affiliates

Except for Tenaris, no other affiliates of the Company reported any Iran related activity for the year ended December 31, 2021.

Other Investments

Usiminas. Usiminas is one of the main producers of flat steel products in Brazil, including iron ore mining, steel production and steel processing and customization. In 2021, Usiminas shipped 4.8 million tons of steel products and 9.0 million tons of iron ore, and had net sales of BRL33.7 billion. Usiminas is a publicly-traded company listed on the São Paulo stock exchange, BM&FBOVESPA S.A - Bolsa de Valores, Mercadorias e Futuros.

On January 16, 2012, Ternium Investments, together with Ternium Argentina (and its subsidiary Prosid), and the Company’s affiliate TenarisConfab, joined Usiminas’ existing control group through the acquisition of a total of 139.7 million ordinary shares of Usiminas, representing 27.7% of Usiminas’ voting capital (22.7% corresponding to Ternium and the other 5% corresponding to TenarisConfab), and formed the T/T Group. As a result of such acquisition, Usiminas’ control group, which at the time held, in the aggregate, 322.7 million ordinary shares representing approximately 63.9% of Usiminas’ voting capital, was formed as follows: NSC Group, with approximately 46.1% of the total shares held by the control group; the T/T Group, with approximately 43.3% of the total shares held by the control group (35.6% corresponding to Ternium and the other 7.7% corresponding to TenarisConfab); and Previdência Usiminas, with the remaining 10.6% of the total shares held by the control group. The members of the control group entered into a shareholders’ agreement dated January 16, 2012 governing their rights and obligations as shareholders of Usiminas.

On October 30, 2014, Ternium acquired 51.4 million additional ordinary shares of Usiminas. As part of a multi-round capital increase process, on June 3, 2016, Ternium (through Ternium Investments, Ternium Argentina and Prosid) was issued, in the aggregate, 8.5 million preferred shares and TenarisConfab was issued 1.3 million preferred shares; and on July 19, 2016, Ternium (through Ternium Investments, Ternium Argentina and Prosid) was issued, in the aggregate, 76.4 million ordinary shares and TenarisConfab was issued 11.5 million ordinary shares. Following the issuance of these ordinary shares, Ternium (through Ternium Investments, Ternium Argentina and Prosid) owns a total of 242.6 million ordinary shares and 8.5 million preferred shares, representing 20.4% of Usiminas’ capital, and 34.4% of Usiminas’ ordinary shares, and TenarisConfab owns a total of 36.5 million ordinary shares and 1.3 million preferred shares, representing 3.1% of Usiminas’ capital, and 5.2% of Usiminas’ ordinary shares.

In 2014, a conflict arose within the Usiminas’ control group and its board with respect to the governance of Usiminas, including with respect to the rules applicable to the appointment of senior managers, the application of the shareholders’ agreement in matters involving fiduciary duties, and generally with respect to Usiminas’ business strategy.

On February 8, 2018, Ternium Investments resolved the dispute with NSC, establishing certain new governance rules for Usiminas as well as certain undertakings for the settlement of legal disputes. Ternium Investments and NSC further agreed to implement such new governance rules by seeking the agreement of the other members of the controlling

69

group, and on April 10, 2018, the T/T Group, NSC Group and Previdência Usiminas entered into a new shareholders’ agreement for Usiminas, amending and restating the January 16, 2012 shareholders’ agreement (the “New SHA”).

The New SHA reflects the agreed-upon corporate governance rules for Usiminas, including, among others, an alternation mechanism for the nomination of each of the chief executive officer and the chairman of the board of directors, as well as a mechanism for the nomination of other members of Usiminas’ executive board. The right to nominate Usiminas’ chief executive officer and chairman will alternate between Ternium and NSC at every 4-year interval, comprising two consecutive 2-year terms. For the initial four years, Ternium was entitled to nominate the CEO and NSC was entitled to nominate the chairman. The executive board is composed of six members, including the chief executive officer and five vice-presidents, with Ternium and NSC nominating three members each.

In addition to the Usiminas shares that were bound by the January 16, 2012 shareholders’ agreement, the New SHA also covers the shares subscribed for by the members of the T/T Group and the NSC Group in connection with Usiminas’ 2016 capital increase. As a result, Usiminas’ control group now holds, in the aggregate, 483.6 million ordinary shares subject to the New SHA, representing approximately 68.6% of Usiminas’ voting capital, with the T/T Group holding approximately 47.1% of the total shares held by the control group (39.5% corresponding to Ternium and the other 7.6% corresponding to TenarisConfab); the NSC Group holding approximately 45.9% of the total shares held by the control group; and Previdência Usiminas holding the remaining 7.1% of the total shares held by the control group.

Finally, the New SHA incorporates an exit mechanism consisting of a buy-and-sell procedure, exercisable at any time during the term of the New SHA after November 16, 2022. Such exit mechanism shall apply with respect to shares held by the NSC Group and the T/T Group, and would allow either Ternium or NSC to purchase all or a majority of the Usiminas shares held by the other shareholder group.

The 51.4 million ordinary shares of Usiminas acquired by Ternium on October 30, 2014 and 6.7 million ordinary shares acquired by NSC prior to execution of the January 16, 2012 shareholders’ agreement remain free from any transfer restrictions under the New SHA and will not be subject to the exit mechanism described above.

In connection with the execution of the New SHA, Ternium Investments, Ternium Argentina, Prosid and TenarisConfab amended and restated their separate shareholders’ agreement governing their respective rights and obligations as members of the T/T Group to include provisions relating to the exit mechanism and generally to conform such separate shareholders’ agreement to the other provisions of the New SHA.

As of December 31, 2021, the closing price of the Usiminas ordinary and preferred shares, as quoted on the BM&F Bovespa Stock Exchange, was BRL14.51 (approximately $2.60) per ordinary share and BRL15.16 (approximately $2.72) per preferred share, respectively. Accordingly, as of December 31, 2021, Ternium’s ownership stake had a market value of approximately $653.9 million and a carrying value of $681.7 million.

Techgen. Techgen is a Mexican joint venture company owned by 48% by Ternium, 30% by Tecpetrol and 22% by Tenaris. Techgen operates a natural gas-fired combined cycle electric power plant in the Pesquería area of the State of Nuevo León, Mexico. Ternium and Tenaris currently contract 78% and 22%, respectively, of Techgen’s power capacity of approximately 900 megawatts. As a result, Ternium is securing the supply of electricity to its existing and future facilities in Mexico, and sells unused energy to the Mexican market. For further information on the Company’s commitments under the Techgen project, see note 24(ii)(d), (h), (l) and (m) to the consolidated financial statements included in this annual report.

This discussion and analysis presents our financial condition and results of operations on a consolidated basis.

Certain information contained in this discussion and analysis and presented elsewhere in this annual report, including information with respect to our plans and strategies for our business, includes forward-looking statements that involve risks and uncertainties. For further information, see “Cautionary Statement Concerning Forward-Looking Statements.” In evaluating this discussion and analysis, you should specifically consider the various risk factors identified in Item 3.D. “Key Information – Risk Factors” in this annual report and others that could cause results to differ materially from those expressed in such forward-looking statements.

Overview

For a description of Ternium’s profile, business strategy and sustainability approach, see Item 4. “Information on the Company—Overview”, “Information on the Company—B. Business Overview—Our Business Strategy” and “Information on the Company—B. Business Overview—Our Sustainable Approach.”

Ternium’s revenues are affected by general global trends in the steel industry and more specifically by the economic conditions in the countries in which it has manufacturing operations and where its customers are located. Ternium’s revenues are also impacted by events that affect the price and availability of raw materials, energy and other inputs needed for its operations. Furthermore, due to the highly cyclical nature of the steel industry, recent results may not be indicative of future performance, and historical results may not be comparable to future results. Investors should not rely on the results of a single period, particularly a period of peak prices, as an indication of Ternium’s annual results or future performance. The variables and trends mentioned below could also affect the results of its investments in steel related companies.

Ternium’s primary source of revenue is the sale of steel products. Management expects sales of steel products to continue to be Ternium’s primary source of revenue. The global market for such steel products is highly competitive, with the primary competitive factors being price, cost, product quality and customer service. The majority of Ternium’s sales are concentrated in the Americas. Specifically, Ternium’s largest markets for finished steel products are Mexico, Argentina, Colombia and the United States, and Ternium’s largest market for slabs is Brazil .

Ternium’s results are sensitive to economic activity and steel consumption. Ternium’s results of operations, which primarily depend on economic conditions in Mexico and Argentina, are also influenced by economic conditions in international and regional markets such as the United States, Mercosur and the Andean Community. Historically, annual steel consumption in the countries where Ternium operates has varied at a rate that is linked to the annual change in each country’s gross domestic product and per capita disposable income. For example, in December 2019, a novel strain of coronavirus (“COVID-19”) surfaced in China and subsequently spread to the rest of the world in early 2020. The rapid expansion of the virus, the surfacing of new strains of the SARS-CoV-2 virus in several countries, and the containment measures adopted by governmental authorities triggered a severe fall in global economic activity and steel demand. This economic downturn had a pronounced negative effect on Ternium’s business and results of operations in the second quarter of 2020. Subsequently, global economic activity and steel demand recovered. A protracted global recession or a depression would have a material adverse effect on the steel industry and Ternium.

71

Ternium’s results are also sensitive to prices in the international steel markets. Steel prices are volatile and are sensitive to supply conditions and to trends in cyclical industries, such as the construction, automotive, appliance and machinery industries, which are significant markets for Ternium’s finished steel products. For example, U.S. steel prices trended down during most of 2019 as a result of softer steel consumption, increased steel production and lower costs of steel scrap. Steel prices decreased further in 2020 during the early stages of the COVID-19 pandemic reflecting a depression in steel consumption. However, after an initial slump, steel prices increased steadily during the rest of 2020 and picked at historical record levels in September 2021, as the speed of the recovery in steel production and in the production of steelmaking raw materials fell short of steel demand. Since then, steel prices decreased rapidly under a normalizing steel supply-demand balance scenario until February 2022, when they raised significantly following the start of the Russia-Ukraine armed conflict. As a result of the historically high steel prices in 2021, Ternium’s operating income increased 388% year-over-year compared to 2020, after increasing 25% year-over-year in 2020 and decreasing 59% year-over-year in 2019. Persistently low steel prices would have a material adverse effect on Ternium’s results, as could price volatility.

Trends in the steel industry may also have an impact on Ternium’s results. In addition to economic conditions and prices, the steel industry is affected by other factors such as worldwide and regional production capacity and fluctuations in steel imports/exports and tariffs. Historically, the steel industry has suffered, especially on downturn cycles, from substantial over-capacity. In the last decade, over-capacity was particularly severe in China. More recently, there are several new steel making and steel processing facilities under construction or ramping-up in North America, which could contribute to an excess of steel production capacity in the coming years in the region. For further information on Ternium’s competition in the Mexican market see Item 4. “Information on the Company—B. Business Overview—Competition—Steel—Mexico”. Furthermore, there has been a trend toward steel industry consolidation among Ternium’s competitors, and current competitors in the steel market could become larger in the future. Intense competition could impact Ternium’s share in certain markets and adversely affect its sales and revenue.

Ternium’s production levels and costs are sensitive to the price and availability of raw materials, semi-finished steel and energy, which reflect supply and demand factors in the global steel industry. Ternium purchases substantial quantities of raw materials (including iron ore, coal, ferroalloys and scrap) and slabs for use in the production of its steel products. The availability and price of these and other inputs vary, sometimes significantly, according to general market and economic conditions. In addition to raw materials and slabs, natural gas is an important component of Ternium’s cost structure. Ternium generally purchases these inputs at market or market-based prices; accordingly, price fluctuations in these inputs, which may also vary according to general market and economic conditions, impact Ternium’s production costs. For example, strong demand coupled with certain supply restrictions, due to the wet season in Australia among other factors, contributed to a new surge in iron ore and metallurgical coal prices in the international markets. More recently, the Russia-Ukraine armed conflict and the consequent wave of international sanctions against Russia are expected to reduce the supply of steelmaking raw materials and steel products in the international markets and, as a result, the availability and pricing of these inputs in the international markets are expected to be volatile and could result in limitations to Ternium’s production levels and/or higher costs.

Ternium’s export revenues could be affected by trade restrictions and its domestic revenues could be affected by unfair competition from imports. During the last decade, steel exports surged as a consequence of a global downturn and an economic slowdown in China, and the number of antidumping, countervailing, safeguard measures and other trade restrictive actions increased substantially, including steel exports to Mexico, Ternium's main steel market, and to the United States. Ternium’s ability to profitably access the export markets may be adversely affected by trade restrictions, including antidumping duties and countervailing measures, in certain markets. In addition, Ternium’s ability to sell some steel products in its principal markets could be affected by unfair competition from imports of those steel products from certain countries, if measures against unfair trade were not in force. For example, in 2018 the United States imposed, under Section 232 of the Trade Expansion Act of 1962, a 25% tariff on steel imports; however, Australia, Canada and Mexico are exempted from the tariff (though subject to a continuous monitoring system of their trade flows); Argentina, Brazil and Korea were excluded at the time with a regime of import quotas. Starting in 2022, the U.S. shifted, in the case of the European Union, the 25% tariff to a Tariff Rate Quota (TRQ) system for steel products melted and poured in this region, and Japan and the United Kingdom will enter into a similar system in April and June 2022, respectively. These trade measures could stimulate aggressive export offers elsewhere, exerting downward pressure on sales and margins of steel companies operating in other markets and regions, including those in which Ternium operates. For further information, see Item 4. “Information on the Company—B. Business Overview—Regulations—Trade Regulations.”

Changes in prevailing exchange rates could impact results from subsidiaries with net short or long positions in currencies other than their functional currencies. Since January 1, 2020, the functional currency of all of Ternium's consolidated subsidiaries is the U.S. dollar. Ternium’s subsidiaries record foreign exchange results on their net non-U.S. dollar positions when the other currencies appreciate or depreciate with respect to the U.S. dollar. In addition, Ternium’s subsidiaries in Mexico, Brazil, Argentina and Colombia record deferred tax results when the Mexican peso,

72

the Brazilian real, the Argentine peso or the Colombian peso appreciates or depreciates in relation to the U.S. dollar (their functional currency) as such fluctuations change, in U.S. dollar terms, the tax base used to calculate deferred tax at such subsidiaries. Fluctuations in the value of such currencies against the U.S. dollar have had, and may also have in the future, an impact on Ternium’s results.

Changes in prevailing exchange rates have had an impact on Ternium’s comprehensive results in the past and could impact comprehensive results from investments with a functional currency other than the U.S. dollar in the future. In accordance with IFRS, Ternium records currency translation adjustments in its consolidated statements of comprehensive income. These adjustments do not affect results but, instead, have an impact on net worth. Fluctuations in the Brazilian real (as our participation in Usiminas is denominated in Brazilian reais) against the U.S. dollar have had, and may also have in the future, an impact on Ternium’s comprehensive results. Ternium’s currency translation adjustments results included the effect of the devaluation of the Brazilian real on the value of Ternium’s investment in Usiminas as measured in U.S. dollars, amounting to a loss of $40.3 million in 2021, $108.8 million in 2020 and 19.7 million in 2019.

Critical accounting estimates.

This discussion of our operating and financial review and prospects is based on the consolidated financial statements included in this annual report, which have been prepared in accordance with IFRS. The use of IFRS has an impact on our critical accounting policies and estimates.

The preparation of financial statements requires management to make estimates and judgements that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Management makes estimates and assumptions concerning the future. Actual results may differ significantly from these estimates under different assumptions or conditions.

An overview of Ternium’s critical accounting policies under which significant judgments, estimates and assumptions are made may be found in note 3(bb) to the consolidated financial statements included in this annual report.

(1)The functional currency of Ternium's subsidiary Ternium Argentina has changed from the Argentine Peso to the US dollar. This change is prospective from January 1, 2020, and does not affect the balances at December 31, 2019, 2018 and 2017, nor results or cash flows for the years then ended.

(2)Other operating income, net, in 2020 included a $186.0 million non-cash gain related to the derecognition of a contingency on ICMS tax benefits at Ternium Brasil (imposto sobre circulação de mercadorias e prestação de serviços). For more information see note 24(i)(f) "ICMS deferral tax benefit – Action of Unconstitutionality" to the consolidated financial statements included in this annual report.

(3)Of the 2,004,743,442 shares issued as of December 31, 2021, the Company held 41,666,666 that were repurchased from Usiminas on February 15, 2011. Such shares were not considered outstanding for purposes of the calculation of the weighted average number of shares.

(4)International Accounting Standard N° 1 (IAS 1) (revised) requires that income for the year as shown in the income statement includes the portion attributable to non-controlling interest. Basic earnings per share and basic earnings per ADS, however, continue to be calculated on the basis of income attributable solely to the owners of the parent.

(5)Diluted earnings per share and per ADS (expressed in $ per share or ADS), equals basic earnings per share or ADS, respectively.

(6)In November 2021, the company paid an interim dividend for fiscal year 2021 of $0.08 per share ($0.80 per ADS). On February 15, 2022, the Company’s board of directors proposed that an annual dividend of $0.26 per share ($2.60 per ADS), be approved at the company’s annual general shareholders’ meeting, which is scheduled to be held on May 3, 2022. The annual dividend would include the interim dividend of $0.08 per share ($0.80 per ADS), paid in November 2021. If the board of directors’ proposal is approved at the shareholders’ meeting, a net dividend of $0.18 per share ($1.80 per ADS), will be paid on May 11, 2022, with record-date on May 6, 2022.

Fiscal Year Ended December 31, 2021 compared to Fiscal Year Ended December 31, 2020

This annual report includes certain non-IFRS alternative performance measures such as Net Cash, Net Debt and Free Cash Flow. The reconciliation of these figures to the most directly comparable IFRS measures is included in Item 19. Exhibits, Exhibit Number 7.2 "Statement explaining alternative performance measures".

Overview

In 2021, an out-of-the-ordinary business environment helped Ternium achieve an outstanding performance in the year. In addition to record financial results, the company started-up, by mid year, the new hot-rolling mill at its industrial center in Pesquería, Mexico. The ramp-up of the new mill enabled Ternium to further expand its presence in the USMCA region and opened-up new growth opportunities for downstream capacity expansions. In this regard, Ternium has recently announced the construction at its industrial center in Pesquería of a new cold-rolling mill, a hot-dip galvanizing line, a push-pull pickling line and new finishing lines. For more information on this investments, see Item 4. “Information on the Company—B. Business Overview—Our Business Strategy.” In addition, Ternium has recently launched an expansion of its Shreveport facility in the U.S. state of Louisiana, with a second coil coating paint line. Furthermore, during 2021 the company progressed with the ramp-up of its new steel bar and coil mill in Palmar de Varela, Colombia.

75

Regarding its financial performance, in 2021 Ternium achieved record levels of profitability and generated significant cash from operations. Net sales in 2021 were $16.1 billion. Steel products net sales were $15.8 billion on steel shipments of 12.1 million tons, other products net sales were $248.3 million and iron ore products net sales were $526.3 million on iron ore shipments of 3.8 million tons. The majority of the iron ore production was consumed in our steel operations. Steel revenue per ton was $1,309 in 2021, significantly higher than in 2020 as a result of a global recovery in steel prices that started in the second half of 2020 and picked at historical record levels in September 2021, as the speed of the recovery in steel production and in the production of steelmaking raw materials fell short of steel demand.

Steel Shipments by Country in 2021

During 2021, shipments in the Mexican market were 6.5 million tons, representing 54% of Ternium’s total steel shipments. Shipments in the Southern Region reached 2.5 million tons in 2021, or 21% of Ternium’s consolidated shipments in the steel segment, most of which are destined for the Argentine market. Shipments in the Other Markets region were 3.0 million tons in 2021, or 25% of Ternium’s consolidated shipments in the steel segment. Our major shipment destinations in the Other Markets region are usually the United States, Brazil, Colombia and Central America. Operating income amounted to $5.3 billion in 2021, the highest on record on strong steel prices and healthy shipment volumes, despite high costs of raw materials and purchased slabs.

The company’s net income in 2021 was $4.4 billion. Equity holders' net income in 2021 was $3.8 billion, equivalent to earnings per ADS of $19.49. Net cash provided by operating activities was $2.7 billion, including a working capital increase of $2.6 billion. In 2021, Ternium’s capital expenditures were $523.6 million, $36.4 million lower than in 2020. Of note during the year were the investments made for Ternium's new hot-rolling mill at the company's Pesquería industrial center in Mexico. With free cash flow of $2.2 billion in 2021 (net cash provided by operating activities of $2.7 billion less capital expenditures of $0.5 billion), Ternium reached a net cash position of $1.2 billion at the end of December 2021 (borrowings of $1.5 billion less cash and cash equivalents plus other investments of $2.7 billion). Net cash position and free cash flow are non-IFRS alternative performance measures. Please see Exhibit 7.2 for more information on these measures.

Net Sales

Net sales in 2021 were $16.1 billion, 84% higher than net sales in 2020. The following table outlines Ternium’s consolidated net sales for 2021 and 2020.

Ternium’s steel shipments in 2021 were 12.1 million tons, up 705,000 tons compared to shipment levels in 2020 reflecting a recovery from the impact of the COVID-19 outbreak on economic activity and steel demand, and the ramp-up of Ternium's new facilities in Mexico and Colombia.

Shipments in Mexico increased 11% year-over-year in 2021, mainly due to higher activity levels in the export-led industrial sector. In the Southern Region, shipments increased 30% year-over-year in 2021 on higher durable goods consumption and increased activity in the construction sector. In the Other Markets region, shipments decreased 14% year-over-year, reflecting lower slab shipments to third parties partially offset by higher finished steel shipments. Revenue per ton reached $1,309 in 2021, the highest on record, increasing $561 compared to revenue per ton in 2020, on higher steel prices in all of Ternium's markets.

Operating income amounted to $5.3 billion in 2021, the highest on record on higher steel prices partially offset by higher costs of raw materials and purchased slabs. The company’s net income in 2021 was $4.4 billion.

Cost of Sales

Cost of sales was $9.9 billion in 2021, an increase of $2.8 billion compared to 2020. This was principally due to a $2.4 billion, or 44%, increase in raw materials and consumables used, mainly reflecting higher purchased slabs and raw material costs and a 6% increase in steel volumes; and to a $394.1 million increase in other costs, mainly including a $211.3 million increase in maintenance expenses, a $143.6 million increase in labor costs and a $38.3 million increase in services and fees.

Selling, General and Administrative (SG&A) Expenses

Selling, General & Administrative (SG&A) expenses in 2021 were $950.1 million, or 6% of net sales, an increase of $187.2 million compared to SG&A expenses in 2020, mainly due to a $79.0 million increase in freight and transportation expenses, a $63.2 million increase in taxes and a $57.8 million increase in labor costs, partially offset by a $33.9 million decrease in amortization of intangible assets.

Operating Income

Operating income in 2021 was $5.3 billion, or 33% of net sales, compared to operating income of $1.1 billion, or 12% of net sales in 2020. The following table outlines Ternium’s operating result by segment for 2021 and 2020:

Net Financial Results

Net financial results were a gain of $92.5 million in 2021, including a $77.3 million gain related to changes in the fair value of financial assets and a $35.9 million gain related to investment returns on the company's liquidity position net of borrowing costs. These positive results were partially offset by a $36.8 million net foreign exchange loss, mainly related to the net negative impact of the depreciation of the Argentine Peso against the US dollar (18% in the year) on the net local currency position of Ternium's Argentine subsidiary. Net financial results in the full year of 2020 were a gain of $22.3 million.

Equity in Results of Non-Consolidated Companies

Equity in results of non-consolidated companies was a gain of $400.7 million in 2021 mainly as a result of Ternium's investment in Usiminas, which included a gain related to a favorable Brazilian Federal Supreme Court ruling in connection with the calculation method for certain sales tax credits. Equity in results of non-consolidated companies in 2020 was a gain of $57.6 million.

Income Tax Expense

Income tax expense in 2021 was $1.4 billion, with a 24% effective tax rate, compared to $291.5 million in 2020, with a 25% effective tax rate.

Net Income Attributable to Non-controlling Interest

Net gain attributable to non-controlling interest in 2021 was $542.1 million, higher than a net gain of $89.4 million in 2020 mainly reflecting improved results at Ternium Argentina

Fiscal Year Ended December 31, 2020 compared to Fiscal Year Ended December 31, 2019

Overview

During 2020, the global economy was deeply affected by the COVID-19 pandemic and the measures taken around the world to contain the spread of the SARS-CoV-2 virus, which resulted in a global crisis with an unprecedented speed and severity in recent history. Although activity levels around the globe improved steadily during the second half of 2020 from a slump in the second quarter, new waves of infection have been spreading in various regions triggering new preventive measures to contain it. There remains considerable uncertainty about the future duration and extent of the pandemic with new and more contagious variants of the virus appearing and the vaccination programs yet in their early stages.

At the start of the COVID-19 outbreak, Ternium took prompt action to mitigate the impact of the pandemic and the crisis, and adapted its operations on a country-by-country basis to comply with applicable rules and requirements. These actions included:

- Occupational health and safety. Ternium prioritizes the occupational health and safety of its employees, customers and suppliers, and has adopted new protocols to ensure a safe working environment involving the use of face masks, temperature checks, strict social distancing and workplace disinfection policies including the Company's transportation, site entry and common working areas. In addition, we have implemented remote working where possible and procedures to track individuals showing compatible COVID-19 symptoms and their close contacts. Throughout the pandemic, Ternium operated all facilities under strict sanitary protocols, which included daily

78

temperature checks for all on-site workers and prompt testing of all individuals to ensure proactive contagion prevention. The Company also conducted an extensive communications program across its facilities to promote health and wellness protocols at both work and home. The Company's digital sales portal, Webservice, contributed to safe working practices by channeling approximately 77% of total orders placed by commercial customers in 2020, with a year-over-year increase in utilization of this portal compared to the 70% achieved before the COVID-19 outbreak. As of the date of this annual report, remote work and other work arrangements have not adversely affected Ternium’s ability to conduct operations. In addition, these alternative working arrangements have not adversely affected our financial reporting systems, internal control over financial reporting or disclosure controls and procedures.

- Operations. Ternium has adjusted its operations to continue to supply steel products to essential sectors and other customers and, at the same time, observe lockdowns and operating restrictions imposed in several jurisdictions. Ternium's training programs were reinforced with webinars and online workshops.

- Liquidity. During the second quarter of 2020, Ternium took steps to ensure the continued strength of its financial position, including the optimization of operations and overhead costs, and the reduction of working capital. In order to mitigate the impact of the then expected lower sales, Ternium reduced its capital expenditure commitments for 2020 by slowing down or postponing investment projects, such as the new hot-rolling mill in Pesquería, Mexico, which is now expected to commence operations during mid-2021. Moreover, on April 28, 2020, Ternium's Board of Directors withdrew its annual dividend proposal for fiscal year 2019. Ternium's net debt position decreased during 2020, from $1.5 billion at the end of December 2019 (borrowings of $2.2 billion less cash and equivalents plus other investments of $0.7 billion) to $371.5 million at the end of December 2020 (borrowings of $1.7 billion less cash and cash equivalents plus other investments of $1.4 billion).

- Support to third parties. To support our small and medium-sized customers and suppliers, we reinforced the financial assistance provided under the ProPymes program and the assistance in obtaining loans from local financial institutions. In addition, new tools were incorporated to ensure the continuity of ProPymes advisory and training activities, on both remote and online formats.

- To support nearby communities, Ternium acted to strengthen medical response capabilities through a special funding program mainly focused on the supply of medical equipment and personal protection gear to community health centers. Reinforcement plans were designed in cooperation with hospital authorities in each of the communities near Ternium's facilities, taking into consideration local population age and available healthcare infrastructure. Under this program, Ternium provided infrastructure and equipment to 14 hospitals and healthcare facilities in four countries, including equipment for intensive care units. In addition, we provided support to health centers in the process of adapting their infrastructure; we manufactured face masks at our facilities and supported local entrepreneurs' initiatives for ventilator manufacturing. In addition, in Monterrey, Mexico, Ternium constructed and operated a field hospital with 100 beds and 10 intensive care units for the community.

- To foster knowledge sharing on COVID-19 disease treatments, we created a network of medical professionals together with our affiliate Tenaris. Seventy doctors from local communities in Mexico, Argentina and Brazil participated in a virtual meeting with their colleagues at Humanitas, an Italian network of hospitals controlled by the Techint Group. Through this platform, Humanitas' know-how on dealing with the COVID-19 outbreak in Italy was made available at a public virtual campus.

- Alongside the Fundación Hermanos Agustín y Enrique Rocca (Agustín and Enrique Rocca Brothers Foundation), and Tenaris, Ternium contributed food for vulnerable families through the #SeamosUno project in Argentina. In addition, Ternium provided food support for families of children participating at its educational programs in Rio de Janeiro, Brazil, and for families of students at the Roberto Rocca Technical School in Pesquería, Mexico.

Ternium's main steel markets contracted in 2020, negatively affected by the impact of the COVID-19 pandemic on economic activity. A trough in steel demand during the second quarter, however, gave way to a steady recovery during the second half of the year, helped by a gradual rebuilding of inventories and a shift in consumption patterns toward consumer durables and housing. Consequently, total steel shipments in 2020 were 11.4 million tons, down 1.2 million tons compared to 2019, mainly reflecting lower shipments of slabs to third parties and of finished steel in the Mexican market.

During 2020, shipments in the Mexican market were 5.9 million tons, representing 52% of Ternium’s total steel shipments. Shipments in the Southern Region were 1.9 million tons in 2020, or 17% of Ternium’s consolidated shipments in the steel segment, most of which are destined for the Argentine market. Shipments in the Other Markets region were 3.5 million tons in 2020, or 31% of Ternium’s consolidated shipments in the steel segment. Our major

79

shipment destinations in the Other Markets region are usually the United States, Brazil, Colombia and Central America.

Net sales in 2020 were $8.7 billion, including steel products net sales of $8.5 billion on steel shipments of 11.4 million tons, other products net sales of $177.7 million and iron ore products net sales of $390.5 million on iron ore shipments of 3.8 million tons. Most of the iron ore production was consumed in our steel operations. Steel revenue per ton was $748 in 2020, lower than revenue per ton in 2019, mainly reflecting a weak steel price environment during the first half of 2020, particularly at the start of the COVID-19 outbreak, partially offset by a consistent recovery during the second half of the year.

Steel Shipments by Country in 2020

The Company’s net income in 2020 was $867.9 million. Equity holders' net income was $778.5 million, equivalent to earnings per ADS of $3.97. Operating income increased year-over-year despite lower shipments, mainly reflecting a $186.0 million non-cash gain related to the derecognition of a contingency on certain tax benefits at Ternium Brasil, lower purchased slab, raw material and energy costs, and the positive impact on costs of weak local currencies vis-a-vis the US dollar, partially offset by lower revenue per ton and the negative impact on costs of lower mill utilization rates. Net cash provided by operating activities was $1.8 billion, including a working capital reduction of $352.8 million. In 2020, Ternium’s capital expenditures were $560.0 million, down 47% year-over-year, reflecting the conclusion of some expansion projects and Ternium's decision to slow or postpone several other projects across its facilities, including its new hot-rolling mill in the company’s Pesquería industrial center in Mexico. The main investments carried out during 2020 included those made for the new hot-rolling mill, the capacity expansion of the pulverized coal injection system in our Rio de Janeiro unit in Brazil, and projects aimed at further improving environmental and safety conditions throughout our main facilities.

Ternium's net debt position reached $371.5 million at the end of December 2020, down from $1.5 billion at the end of December 2019. Net debt in 2020 is calculated as borrowings of $1.7 billion less cash and cash equivalents plus other investments of $1.4 billion, and in 2019 as borrowings of $2.2 billion less cash and cash equivalents plus other investments of $0.7 billion. Net debt position is a non-IFRS alternative performance measure. Please see Exhibit 7.2 for more information on these measure.

Net Sales

Net sales in 2020 were $8.7 billion, 14% lower than net sales in 2019. The following table outlines Ternium’s consolidated net sales for 2020 and 2019.

* The item “Other products” primarily includes Ternium Brasil's and Ternium Mexico's electricity sales.

Shipments in Mexico, Ternium's main steel market, decreased 6% year-over-year to 5.9 million tons. The country's manufacturing industries gradually ramped up production during the second half of 2020, following a trough in the second quarter, and achieved pre-pandemic levels during the fourth quarter.

Ternium's shipments in the Southern Region reached 1.9 million tons in 2020, down 1% year-over-year. Activity in the construction and industrial sectors recovered during the second half of 2020, supported by increased demand of durable goods and construction materials in Argentina. This shift in consumption patterns led to a high level of shipments in the fourth quarter, above those prevailing before the COVID-19 outbreak.

In the Other Markets region, Ternium's finished steel shipments in 2020 were slightly down year-over-year with lower shipments in Colombia, due to the impact of the pandemic, and higher shipments in the US market. During the second half of 2020, our slab facility in Brazil returned to full capacity from minimum utilization rates in April, and increased its integration with other Ternium's mills.

Cost of Sales

Cost of sales was $7.1 billion in 2020, a decrease of $1.4 billion compared to 2019. This was principally due to a $1.2 billion, or 18%, decrease in raw material and consumables used, mainly reflecting a 9% decrease in steel shipment volumes and lower purchased slabs, raw material and energy costs; and to a $186.9 million decrease in other costs, mainly including a $95.7 million decrease in maintenance expenses, a $65.6 million decrease in labor costs and a $38.4 million decrease in services and fees partially offset by a $18.3 increase in depreciation of property, plant and equipment.

Selling, General and Administrative (SG&A) Expenses

SG&A expenses in 2020 were $762.9 million, or 9% of net sales, a decrease of $134.6 million compared to SG&A expenses in 2019 mainly due to $45.1 million decrease in amortization of intangible assets, a $34.7 million decrease in services and fees and office expenses, a $22.6 million decrease in labor costs, a $24.2 million decrease in freight and transportation and a $6.9 million decrease in taxes.

Other net operating income

Other net operating income in 2020 was $206.8 million, compared to other net operating income of $21.7 million in 2019. Other operating income in 2020 included a $186.0 million non-cash gain related to the derecognition of a contingency on ICMS tax benefits at Ternium Brasil (imposto sobre circulação de mercadorias e prestação de serviços). For more information, see note 8 “Other operating income (expenses), net" and 24(i)(f) "Contingencies, commitments and restrictions on the distribution of profits” to our consolidated financial statements included in this annual report.

Operating Income

Operating income in 2020 was $1.1 billion, or 12% of net sales, compared to operating income of $864.6 million, or 8% of net sales in 2019. The following table outlines Ternium’s operating income by segment for 2020 and 2019:

Net Financial Results

Net financial results were a $22.3 million gain in 2020, mainly reflecting investment returns on Ternium's liquidity position. In 2019, net financial results were a loss of $99.0 million.

Equity in Results of Non-Consolidated Companies

Equity in results of non-consolidated companies was a gain of $57.6 million in 2020, compared to a gain of $61.0 million in 2019 mainly due to lower results from Ternium's investment in Usiminas partially offset by higher results from Ternium's investment in Techgen.

Income Tax Expense

Income tax expense in 2020 was $291.5 million or an effective tax rate of 25%, compared to $196.5 million in 2019, or an effective tax rate of 24%.

Net Income Attributable to Non-controlling Interest

Net gain attributable to non-controlling interest in 2020 was $89.4 million, higher than a net gain of $65.8 million in 2019 mainly reflecting improved results at Ternium Argentina.

B.    Liquidity and Capital Resources

We obtain funds from our operations, as well as from short-term and long-term borrowings from financial institutions. These funds are primarily used to finance our working capital and capital expenditures requirements, as well as our acquisitions and dividend payments (for further information on capital expenditures, see Item 4. “Information on the Company—B. Business Overview—Capital Expenditure Program”). We hold money market investments, time deposits and variable-rate or fixed-rate securities.

Principal Sources of Funding

Funding Policy

Management’s policy is to maintain a high degree of flexibility in operating and investment activities by maintaining adequate liquidity levels and ensuring access to readily available sources of financing. Whenever feasible, management bases its financing decisions, including the election of currency, term and type of the facility, on the intended use of proceeds for the proposed financing and on costs. For information on our financial risk management, see note 28 “Financial risk management” to our consolidated financial statements included in this annual report. Ternium has in place non-committed credit facilities and management believes it has adequate access to the credit markets. Considering our financial position and the funds provided by operating activities, management believes that we have sufficient resources to satisfy our current working capital needs, service our debt and pay dividends.

With cash and cash equivalents of $1.3 billion and other investments of $1.4 billion, Ternium achieved net cash position of $1.2 billion as of December 31, 2021 (borrowings of $1.5 billion less cash and cash equivalents plus other investments of 2.7 billion). This compares to net debt position of $0.4 billion as of December 31, 2020 (borrowings of $1.7 billion less cash and cash equivalents plus other investments of 1.4 billion). Management believes that our liquidity and capital resources give us adequate flexibility to manage our financial commitments and planned capital spending programs, and to address short-term changes in business conditions. Net cash and net debt position are non-IFRS alternative performance measures. Please see Exhibit 7.2 for more information on these measures.

Financial Liabilities

Our financial liabilities consist mainly of loans with financial institutions. As of December 31, 2021, these facilities were mainly denominated in U.S. dollars (93% of total financial liabilities). Total financial debt (inclusive of principal and interest accrued thereon) decreased by $243.9 million in the year, from $1.7 billion as of December 31, 2020, to $1.5 billion as of December 31, 2021.

The following table shows Ternium’s financial liabilities as of December 31 of each of the last three years:

84

$ million	2021	2020	2019
Bank borrowings (1)	1,479	1,723	2,189
Total borrowings	1,479	1,723	2,189

(1)Net of debt issuance costs.

Ternium’s cost of debt, as measured by the weighted average interest rate, was 1.45% in 2021, compared to a 1.43% average interest rate in 2020. This rate was calculated using the rates set for each instrument in its corresponding currency and weighted using the U.S. dollar-equivalent outstanding principal amount of each instrument as of December 31, 2021. Such rates do not include the effect of derivative financial instruments, nor fluctuations in the exchange rate between the instrument’s currencies and the U.S. dollar.

The following table shows the weighted-average interest rates as of December 31 of each of the last three years:

	2021		2020		2019
Bank borrowings	1.45	%	1.43	%	2.94	%

As of December 2021, current borrowings were 56% of total borrowings, none of which corresponded to borrowings with related parties. As of December 31, 2021, the maturities of our financial liabilities were as follows:

$ million	1 year	1 – 2	2 – 3	3 – 4	4 – 5	Over 5
At December 31, 2021	Or less	Years	Years	Years	Years	Years	Total

Item 6.    Directors, Senior Management and Employees

A.    Directors and Senior Management

86

Board of Directors

Management of the Company is vested in a board of directors with the broadest power to act on behalf of the Company and to accomplish or authorize all acts and transactions of management and disposal that are within its corporate purpose and not specifically reserved in the articles of association or by applicable law to the general shareholders’ meeting. The Company's articles of association provide for a board of directors consisting of a minimum of three and a maximum of fifteen directors; however, for as long as the Company's shares are listed on at least one regulated market, the minimum number of directors must be five. The Company's current board of directors is composed of eight directors.

The board of directors is required to meet as often as required by the interests of the Company and at least four times per year. In 2021, the Company’s board of directors met seven times. A majority of the members of the board of directors in office present or represented at the board of directors' meeting constitutes a quorum, and resolutions of the board of directors may be adopted by the vote of a majority of the directors present or represented. In case of a tie, the chairman is entitled to cast the deciding vote.

Directors are elected at the annual ordinary general shareholders’ meeting to serve one-year renewable terms, as determined by the general shareholders’ meeting. The general shareholders’ meeting also determines the number of directors that will constitute the board and their compensation. The general shareholders’ meeting may dismiss all or any member of the board of directors at any time, with or without cause, by resolution passed by a simple majority vote.

On January 9, 2006, Tenaris and a wholly owned subsidiary of San Faustin entered into a shareholders’ agreement, pursuant to which the San Faustin subsidiary is required to take all actions in its power to cause one of the members of the Company’s board of directors to be nominated by Tenaris and any directors nominated by Tenaris to be removed only pursuant to written instructions by Tenaris. Tenaris and the San Faustin subsidiary also agreed to cause any vacancies on the board of directors to be filled with new directors nominated by either Tenaris or the San Faustin subsidiary, as applicable. On April 27, 2007, the San Faustin subsidiary assigned all of its rights and obligations under the shareholders’ agreement to Techint. The shareholders’ agreement will remain in effect so long as each of the parties holds at least 5% of the shares of the Company or until it is terminated by either Tenaris or Techint pursuant to its terms. Carlos A. Condorelli was nominated by Tenaris and appointed as a director of the Company pursuant to such shareholders' agreement.

The Company's articles of association provide that the board of directors of the Company may, within the limits of applicable law, (a) delegate to one or more persons, whether or not members of the board of directors, the Company’s day-to-day management and the authority to represent the Company, provided, however, that the delegation of the Company's day-to-day management and representation authority to a member of the board of directors shall be subject to the prior authorization of the general shareholders' meeting, (b) delegate to one or more persons, whether or not members of the board of directors, the powers necessary to carry out the Company's decisions (except for approval of material transactions with related parties), (c) confer to one or more persons, whether or not members of the board of directors, the powers deemed to be appropriate for the general technical, administrative and commercial management of the Company, and (d) constitute and determine the responsibilities, powers and authority (including without limitation an audit committee), the members of which may be selected either from among the directors or outside thereof. On May 3, 2021, the board of directors appointed the Company's chief executive as administrateur délégué and delegated to him the power to manage the Company's affairs within the ordinary course of business, to the full extent permitted by Luxembourg law, to direct and supervise the business activities of the Company's subsidiaries and to represent the Company in relation to such matters.

On May 3, 2021, the Company’s annual general shareholders’ meeting resolved to reduce the number of directors to eight and approved the re-election of: Mr. Roberto Bonatti, Mr. Carlos Alberto Condorelli, Ms. Gioia Ghezzi, Mr. Vincent Robert Gilles Decalf, Mr. Adrian Lajous Vargas, Mr. Gianfelice Mario Rocca, Mr. Paolo Rocca and Mr. Daniel Agustín Novegil as members of the board of directors.

Directors' Liability

Each director must act in the interest of the Company, and in accordance with applicable laws, regulations, and the Company’s articles of association. Directors are also bound by a general duty of care owed to the Company.

Under the Luxembourg law of August 10, 1915 on commercial companies, as amended (the "Luxembourg Company Law"), directors may be liable to the Company in accordance with general law for the execution of their mandate and for any misconduct in the management of the Company's affairs. Directors are jointly and severally liable towards either the Company or any third parties from damages resulting from the violation of the Luxembourg Company Law or the Company’s articles of association. Directors shall be discharged from such liability in the case of a violation to which they were not a party, provided no misconduct is attributable to them and such violation has been reported to the first general meeting of shareholders after they have acquired knowledge thereof.

Causes of action against directors for damages may be initiated by the Company upon a resolution of the general shareholders’ meeting passed by a simple majority vote, irrespective of the number of shares represented at the meeting. Causes of action against directors who misappropriate corporate assets or commit a breach of trust may be brought by any shareholder for personal losses different from those of the Company.

An action may also be brought against the directors on behalf of the Company by shareholders who, at the general meeting which decided upon discharge of such directors or members, owned voting securities representing at least ten per cent of the votes attaching to all such securities.

It is customary in Luxembourg that the shareholders expressly discharge the members of the board of directors from any liability arising out of or in connection with the exercise of their mandate when approving the Company’s annual accounts at the annual shareholders’ meeting. However, such discharge will not release the directors from liability for any damage caused by unrevealed acts of mismanagement or unrevealed breaches of Luxembourg Company Law or

89

the Company’s articles of association, nor will it release directors from liability for any personal loss of the shareholders independent and separate from the losses suffered by the Company due to a breach either revealed or unrevealed of either the Luxembourg Company Law or the Company’s articles of association.

Under Luxembourg law, unless the decision of the board of directors relates to ordinary business entered into under normal conditions, any director having a direct or indirect financial interest conflicting with that of the Company in a transaction which has to be considered by the board of directors, must advise the board thereof and cause a record of her/his statement to be included in the minutes of the meeting and may not take part in the deliberations. At the next following general meeting, before any other resolution is put to vote, a special report must be made on any transactions in which any of the directors may have had an interest conflicting with that of the Company.

Auditors

The Company’s articles of association require the appointment of an independent audit firm in accordance with applicable law. The primary responsibility of the auditor is to audit the Company's annual accounts and consolidated financial statements and to submit a report on the accounts to shareholders at the annual shareholders' meeting. In accordance with applicable law, statutory auditors (réviseur d'entreprises) are chosen among the members of the Luxembourg Institute of Independent Auditors (Institut des réviseurs d’entreprises).

Auditors are appointed by the general shareholders' meeting upon recommendation from the Company's audit committee through a resolution passed by a simple majority vote, irrespective of the number of shares represented at the meeting, to serve one-year renewable terms. Auditors may be dismissed for reasonable cause by the general shareholders' meeting at any time, at the board of director's recommendation or, if the shares of the Company are listed on a regulated market, at the audit committee's recommendation. Luxembourg law does not allow directors to serve concurrently as external auditors. As part of their duties, the auditors report directly to the audit committee.

Pursuant to its charter, the Company’s audit committee is responsible for, among other things, the oversight of the independence and performance of the Company’s external auditors. The audit committee is also responsible to consider and make recommendations to the board of directors, to be put to shareholders for approval at the annual general meeting of shareholders, regarding the appointment, re-appointment or removal of the Company’s external auditors. In addition, the audit committee is responsible to review the appropriateness and provision of permitted non-audit fees and to review and approve any fees (whether for audit, audit-related and non-audit services) payable to the Company’s external auditors. On a yearly basis, in the performance of its functions, the audit committee considers the appointment of the Company’s external auditors and reviews, together with management and the external auditor, the audit plan, audit related services and other non-audit services. The audit committee requests the board of directors to submit the audit committee’s recommendation for the appointment of the Company’s external auditor for each fiscal year and the payment of applicable fees, for final approval by the general shareholders’ meeting. The general shareholders’ meeting regularly approves such audit fees and authorizes the audit committee to approve any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the circumstances. No services outside the scope of the audit committee’s approval can be undertaken by the external auditor.

The shareholders' meeting held on May 3, 2021, re-appointed PwC Luxembourg as the Company’s statutory auditor for the fiscal year ended December 31, 2021. At the next annual general shareholders’ meeting scheduled to be held on May 3, 2022, it will be proposed that PwC Luxembourg be reappointed as the Company’s statutory auditors for the fiscal year ending December 31, 2022.

Audit Committee

Pursuant to the Company’s articles of association, as supplemented by the audit committee’s charter, for as long as the Company’s shares are listed on at least one regulated market, the Company must have an audit committee composed of at least three members, the majority of whom must qualify as independent directors, provided, however, that the composition and membership of the audit committee shall satisfy such requirements as are applicable to, and mandatory for, audit committees of issuers such as the Company under any law, rule or regulation applicable to the Company (including, without limitation, the applicable laws, rules and regulations of such regulated market or markets).

Under the Company’s articles of association, an independent director is a director who:

(i)is not employed, and has not been employed in an executive capacity by the Company or any of its subsidiaries within the five years preceding the ordinary general shareholders’ meeting at which the candidate for the board of directors was voted upon;

(ii)does not receive consulting, advisory or other compensatory fees from the Company or any of its subsidiaries (other than fees received as a member of the board of directors of any committee thereof and fees received as a member of the board of directors or other governing body, or any committee thereof, of any of the Company’s subsidiaries);

(iii)is not a person who directly or indirectly controls the Company;

(iv)does not have, and does not control a business entity that has, a material business relationship with the Company, any of its subsidiaries or a person who directly or indirectly controls the Company, if such material business relationship would reasonably be expected to adversely affect the director’s ability to properly discharge his or her duties;

(v)does not control directly or indirectly, and is not and has not been, within the five years preceding the ordinary general shareholders’ meeting at which the candidate for the board of directors was voted upon, employed by a present or former internal or external auditor of the Company, any of its subsidiaries or a person who directly or indirectly controls the Company; and

(vi)is not a spouse, parent, sibling or relative up to the third degree of, and does not share a home with, any of the persons listed above.

The audit committee of the Company's board of directors currently consists of three members, Ms. Gioia Ghezzi, Mr. Vincent Robert Gilles Decalf and Mr. Adrián Lajous Vargas, who were appointed to the audit committee by the Company's board of directors on May 3, 2021. As of the date of this annual report, all members of the audit committee qualify as independent directors both for purposes of the U.S. Securities Exchange Act Rule 10A-3(b)(1) and under the Company's articles of association.

The Company's audit committee operates under a charter that was amended and restated by the board of directors on November 2, 2021. The audit committee assists the board of directors in fulfilling its oversight responsibilities with respect to the integrity of the Company’s financial statements, including periodically reporting to the board of directors on its activity; and the adequacy of the Company’s systems of internal control over financial reporting. The audit committee is also responsible for making recommendations regarding the appointment, compensation, retention and oversight of, and for assessing the independence of, the Company’s external auditors (see Item 16.C “—Principal Accountant Fees and Services” for additional information about the audit committee’s procedures with respect to our independent auditors). The audit committee also performs other duties imposed by applicable laws, and by regulations of the markets on which the Company's securities are listed, as well as any other duty entrusted to it by the Company’s board of directors.

In addition, the audit committee is required by the Company’s articles of association and audit committee’s charter to review and, where applicable, approve material transactions between the Company or its subsidiaries and related

93

parties, as provided in the Company’s articles of association and audit committee’s charter, or as may be required by any law, rule or regulation applicable to the Company, in order to determine whether their terms are consistent with the interests of the Company and all its shareholders and are consistent with market conditions or are otherwise fair to the Company and its subsidiaries. The Company has adopted a Related Party Transactions Policy and Procedure contemplating consolidated guidelines and procedures for the identification, review, approval and management of related party transactions, seeking to assure transparency and substantial and procedural fairness of such transactions, as well as compliance with the provisions in the Company’s articles of association and the audit committee’s charter relating to transactions with related parties, Luxembourg rules relating to the approval and disclosure of material related party transactions and Section 314.00 of the NYSE Listed Company Manual.

Under the Company’s articles of association, as supplemented by the Related Party Transactions Policy and Procedure, a “related party” is any of the following persons: (i) any affiliate of the Company; (ii) any entity in which a controlling person owns a substantial interest or over which a controlling person can exercise significant influence; (iii) any unconsolidated entity in which the Company has significant influence; (iv) any entity or individual having significant influence over the Company, or a close family member of any such individual; (v) any individual or entity that is the beneficial owner of five percent (5%) or more of the shares of the Company, including through the ownership of any securities representing shares of the Company; (vi) any director or executive officer of any of the controlling persons, the Company or any of the subsidiaries, or a close family member of any such director or executive officer; (vii) any entity in which a substantial interest in the voting power is owned, directly or indirectly, by any person described in (iv), (v) or (vi) above or over which such a person is able to exercise significant influence; or (viii) any entity that has a member of key management in common with the Company or any of its subsidiaries (provided that key management personnel includes persons having authority and responsibility for planning, directing and controlling the activities of an entity, including directors and executive officers and close family members of any such individuals).

With respect to the materiality threshold for review and approval of related party transactions, the Company’s articles of association, as supplemented by the audit committee’s charter and the Related Party Transactions Policy and Procedure, provide that the following related party transactions, which are qualified as “Level 1” related party transactions, are subject to review by the audit committee, which shall make a recommendation to the board of directors as to either reject or approve the proposed related party transaction:

(i)     any transaction between the Company or its subsidiaries with related parties (i) with an individual value equal to or greater than $10 million, or its equivalent in other currencies, or (ii) with an individual value lower than $10 million, or its equivalent in other currencies, when the aggregate sum reflected in the financial statements of the four fiscal quarters preceding the date of determination- of any series of transactions for such lower value that can be deemed to be parts of a unique or single transaction (but excluding any transactions that were reviewed and approved by Company’s audit committee or board of directors, as applicable, or the independent members of the board of directors of any of its subsidiaries) exceeds 1.5% of the Company’s consolidated net sales made in the fiscal year preceding the year on which the determination is made; and

(ii)    any corporate reorganization transaction (including a merger, spin-off or bulk transfer of a business) affecting the Company or any of its subsidiaries for the benefit of, or involving, a related party.

In addition, any related party transaction that does not qualify as a “Level 1” related party transaction, but which has an individual value equal to or higher than such value threshold as management may from time to time determine as material to the Company for disclosure purposes under Item 7.B of this annual report, qualifies as a “Level 2” related party transaction and must be reviewed by the audit committee for purposes of making a determination as to whether any conflicts of interest exist and whether the proposed related party transaction is consistent with the interests of the Company and all shareholders, in order to either reject or approve the proposed transaction. Any related party transaction that is less than such value qualifies as a “Level 3” related party transaction and is reviewed by the Company’s related-party transaction unit, the area within the Company responsible for centralizing and compiling the information relating to all related party transactions and performing the review, assessment and other procedures contemplated in the Related Party Transactions Policy and Procedure.

The audit committee has the power (to the maximum extent permitted by applicable laws) to request that the Company or relevant subsidiary promptly provide all information necessary for the audit committee to assess the material transactions with related parties that it is required to review. In no event may any proposed related party transaction be entered into or otherwise be given effect unless it has been reviewed and approved in accordance with the Related Party Transactions Policy and Procedure. Any executed transaction that has not been duly reviewed and approved must be promptly submitted for review in accordance with applicable procedures and, if determined appropriate, must be ratified; if the transaction is not ratified, it must be modified to make it acceptable for ratification or it must otherwise be immediately discontinued or rescinded.

94

The audit committee has the authority to conduct any investigation appropriate to the fulfilment of its responsibilities, and has direct access to the Company’s external auditors as well as anyone in the Company and, subject to applicable laws and regulations, its subsidiaries. In addition, the audit committee may engage, at the Company's expense, independent counsel and other internal or external advisors to review, investigate or otherwise advise on, any matter as the committee may determine to be necessary to carry out its purposes and responsibilities.

We believe that we enjoy good or satisfactory relations with our employees and their unions in each of the countries in which we have manufacturing facilities, and we have not experienced any major strikes or other labor conflicts with a material impact on our operations over the last five years.

In Argentina, significant fluctuations in exchange rates, together with inflationary pressures, affect our costs, increase labor demands and could eventually generate higher levels of labor conflicts.

At Ternium, we promote a culture of industrial and technological excellence. To achieve this goal, we focus our efforts on fostering innovation, enhancing employees' skills in a challenging atmosphere, implementing succession plans for key positions and shaping an appealing working environment. In addition, Ternium aims to be an equal opportunity and equal treatment organization. We seek to increase diversity at Ternium's management positions and engage the communities and the supply chain under a concerted strategy to empower women. For more information on Ternium's initiatives, see Item 4. “Information on the Company—B. Business Overview— Our Sustainable Approach”

Item 8.    Financial Information

A.    Consolidated Statements and Other Financial Information

See Item 18 and pages F-1 through F-86 for Ternium’s consolidated financial statements.

Legal Proceedings

Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows.

Outstanding Legal Proceedings

The following legal proceedings were outstanding as of the date of this report:

Companhia Siderúrgica Nacional (CSN) – Tender offer litigation

In 2013, the Company was notified of a lawsuit filed in Brazil by Companhia Siderúrgica Nacional, or CSN, and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and TenarisConfab. The entities named in the CSN lawsuit had acquired a participation in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL 28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group; Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals of São Paulo maintained the understanding of the first instance court. On March 6, 2017, CSN filed a motion for clarification against the decision of the court of appeals, which was rejected on July 19, 2017. On August 18, 2017, CSN filed with the court of appeals an appeal seeking the review and reversal of the decision issued by the court of appeals by the Superior Court of Justice. On March 5, 2018, the court of appeals ruled that CSN’s appeal did not meet the requirements for review by the Superior Court of Justice and rejected such appeal. On May 8, 2018, CSN appealed against such ruling and on January 22, 2019, the court of appeals rejected such appeal and ordered that the case be submitted to the Superior Court of Justice. On September 10, 2019, the Superior Court of Justice declared CSN’s appeal admissible. The Superior Court of Justice will review the case and will then render a decision on the merits.

99

The Superior Court of Justice is restricted to the analysis of alleged violations to federal laws and cannot assess matters of fact.

Ternium continues to believe that all of CSN’s claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator (CVM) in February 2012 and December 2016, and the first and second instance court decisions referred to above. Accordingly, no provision has been recorded in Ternium’s consolidated financial statements.

Shareholder claims relating to the October 2014 acquisition of Usiminas shares

On April 14, 2015, the staff of CVM, determined that an acquisition of additional ordinary shares of Usiminas by Ternium Investments made in October 2014, triggered a requirement under applicable Brazilian laws and regulations for Usiminas’ controlling shareholders to launch a tender offer to all non-controlling holders of Usiminas ordinary shares. The CVM staff’s determination was made further to a request by NSSMC and its affiliates, who alleged that Ternium’s 2014 acquisition had exceeded a threshold that triggers the tender offer requirement. In the CVM staff’s view, the 2014 acquisition exceeded the applicable threshold by 5.2 million shares. On April 29, 2015, Ternium filed an appeal to be submitted to the CVM’s Board of Commissioners. On May 5, 2015, the CVM staff confirmed that the appeal would be submitted to the Board of Commissioners and that the effects of the staff’s decision would be stayed until such Board rules on the matter.

On June 15, 2015, upon an appeal filed by NSSMC, the CVM staff changed its earlier decision and stated that the obligation to launch a tender offer would fall exclusively on Ternium. Ternium’s appeal has been submitted to the CVM’s Board of Commissioners and it is currently expected that such Board will rule on the appeal in 2021. In addition, on April 18, 2018, Ternium filed a petition with the CVM’s reporting Commissioner requesting that the applicable threshold for the tender offer requirement be recalculated taking into account the new ordinary shares issued by Usiminas in connection with its 2016 BRL 1 billion capital increase and that, in light of the replenishment of the threshold that would result from such recalculation, the CVM staff’s 2015 determination be set aside. In the event the appeal is not successful, under applicable CVM rules Ternium may elect to sell to third parties the 5.2 million shares allegedly acquired in excess of the threshold, in which case no tender offer would be required.

Potential Mexican income tax adjustment

In March 2015, the Mexican tax authorities, as part of a tax audit to Ternium Mexico with respect to fiscal year 2008, challenged the deduction by Ternium Mexico’s predecessor IMSA Acero of a tax loss arising from an intercompany sale of shares in December 2008. Although the tax authorities have not yet determined the amount of their claim, they have indicated in a preliminary report that they have observations that may result in an income tax adjustment currently estimated at approximately $56.4 million, including interest and fines. Additionally, in September 2018, the Mexican tax authority, as a result of a tax audit for the fiscal year 2011 to Ternium Mexico, as predecessor of APM, objected mainly the deduction of the tax loss remaining for the year 2008, for which the estimated income tax adjustment would be of approximately $27.6 million, including interest and fines.

Ternium Mexico requested an injunction from the Mexican courts against the audit observations for the year 2008 and the fiscal credit of the year 2011, and also filed its defense and supporting documents with the Mexican tax authorities. The injunction for the year 2008 had a favorable resolution to Ternium Mexico in August 2020; consequently, in November 2020, the Mexican tax authorities issued a new preliminary report in which continues having the same observations with different arguments that may result in the same tax adjustment as per the above-included paragraph. The Company, based on the advice of counsel, believes that an unfavorable outcome in connection with this uncertain tax position is not probable and, accordingly, no provision has been recorded in Ternium’s consolidated financial statements.

Fishermen associations’ claims

Civil contingencies include lawsuits brought by a number of fishermen associations on behalf of their associates, alleging that the dredge of Ternium Brasil’s deep-water port has had a negative impact on fish farming and exploitation activities in the Sepetiba Bay area in Rio de Janeiro and that, as a result, fishermen in that area had suffered damages. A provision in the amount of $24.5 million was recorded at the acquisition date in connection with this matter ($8.8 million and $10.9 million as of December 31, 2021 and 2020, respectively).

Tax assessments relating to the use of certain ICMS tax credits

100

The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços, or ICMS, is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties.

The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not qualify as “raw materials” or “intermediary products” but as “goods for consumption” and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed the Rio de Janeiro State Treasury Office’s tax assessments and fines. A provision in the amount of $57.7 million was recorded as of the acquisition date in connection with this matter ($32.5 million and $34.9 million as of December 31, 2021 and 2020, respectively).

Dividend Policy

The Company does not have, and has no current plans to establish, a formal dividend policy governing the amount and payment of dividends or other distributions. For a description of the shareholders’ and holders of ADS’ rights to receive dividends and the conditions to declare and pay dividends, please refer to Item 10. “Additional Information—B. Memorandum and Articles of Association—Dividends”.

The following table shows the dividends approved by the Company’s shareholders in the last five years:

Shareholders’ meeting date	Approved dividend			Dividend payment date
	Amount ($ million)	Per share ($)	Per ADS ($)
May 3, 2017	196.3	0.100	1.00	May 12, 2017
May 2, 2018	215.9	0.110	1.10	May 10, 2018
May 6, 2019	235.6	0.120	1.20	May 14, 2019
May 3, 2021	412.2	0.210	2.10	May 11, 2021

On February 15, 2022, the Company’s board of directors proposed that an annual dividend of $0.26 per share ($2.60 per ADS), or $510.4 million in the aggregate, be approved at the company’s annual general shareholders’ meeting, which is scheduled to be held on May 3, 2022. The annual dividend would include the interim dividend of $0.08 per share ($0.80 per ADS), or $157.0 million, paid in November 2021. If the board of directors’ proposal is approved at the shareholders’ meeting, a net dividend of $0.18 per share ($1.80 per ADS), or $353.4 million in the aggregate, will be paid on May 11, 2022, with record-date on May 6, 2022. For more information, see “Item 5G. Operating and Financial Review and Prospects –Recent Developments – Annual Dividend Proposal”.

B.    Significant Changes

On February 24, 2022, Russia launched a military attack on Ukraine. In response, the United States, the United Kingdom, and the European Union, among other countries, have imposed a wave of sanctions against certain Russian institutions, companies and citizens. As a result of the armed conflict and related sanctions, energy prices have spiked and foreign trade transactions involving Russian and Ukrainian counterparties have been severely affected.

Russia has a significant participation in the international trade of steel slabs, iron ore pellets, metallurgical coal, pulverized coal for injection, which are relevant inputs for Ternium’s operations. In addition, Ukraine has a relevant participation in the international trade of steel slabs and iron ore pellets. The availability and pricing of these inputs in the international markets are expected to be volatile and could result in limitations to Ternium’s production levels and higher costs, affecting the Company’s profitability and results of operations. As a result of the economic sanctions imposed on Russia, Ternium or its contractors (including shipping companies) may not be able to continue purchasing or transporting products from, or making payments to, Ukrainian or Russian suppliers or counterparties; and the Company may not be able to promptly procure such raw materials from other suppliers, or may be required to purchase raw materials at increased prices. For further information related to raw materials, energy and other inputs

requirements see Item 4. “Information on the Company—B. Business Overview—Raw Materials, Slabs, Energy and Other Inputs” and “The recent Russian-Ukraine armed conflict and the consequent wave of international sanctions against Russia are expected to reduce the supply of steelmaking raw materials and steel products in the international markets, including slabs, pulverized coal for injection, and certain metals and ferroalloys.

General

The following is a summary of certain rights of holders of the Company’s shares. These rights are set out in the Company’s articles of association or are provided by applicable Luxembourg law, and may differ from those typically provided to shareholders of U.S. companies under the corporation laws of some states of the United States. This summary is not exhaustive and does not contain all information that may be important to you. For more complete information, you should read the Company’s articles of association, which are attached as an exhibit to this annual report.

The Company is a public limited liability company (société anonyme) organized under the laws of Luxembourg. Its object and purpose, as set forth in Article 2 of its articles of association, is the taking of interests, in any form, in

102

corporations or other business entities, and the administration, management, control and development thereof. The Company is registered under the number B98 668 in the Luxembourg Registre de Commerce et des Sociétés.

The Company’s authorized share capital is fixed by the Company’s articles of association, as amended from time to time, with the approval of shareholders at an extraordinary general shareholders’ meeting. The Company has an authorized share capital of a single class of 3,500,000,000 shares having a nominal value of $1.00 per share. There were 2,004,743,442 shares issued as of the date of this annual report. All issued shares are fully paid.

The Company’s articles of association authorize the board of directors, or any delegate(s) duly appointed by the board of directors, to issue shares within the limits of its authorized share capital against contributions in cash, contributions in kind or by way of incorporation of available reserves, at such times and on such terms and conditions, including the issue price, as the board of directors, or its delegate(s) may in its or their discretion resolve.

The Company’s extraordinary shareholders meeting held on June 5, 2020 approved the renewal for an additional five-year period of the authorization granted to the board of directors to waive, suppress or limit any preemptive subscription rights of shareholders provided for by law to the extent it deems such waiver, suppression or limitation advisable for any issue or issues of shares within the authorized share capital; and have waived any preemptive subscription rights provided for by law and related procedures. The validity period of such authorization will expire on June 19, 2025. However, under the Company's articles of association, for as long as the Company’s shares are listed on a regulated market (and only for as long as they are so listed), any issuance of shares for cash within the limits of the authorized share capital shall be subject to the preemptive subscription rights of the then existing shareholders, except in the following cases (in which cases no preemptive rights shall apply):

(a) any issuance of shares for, within, in conjunction with or related to, an initial public offering of the Company’s shares on one or more regulated markets (in one or more instances);

(b) any issuance of shares against a contribution other than in cash;

(c) any issuance of shares upon conversion of convertible bonds or other instruments convertible into shares of the Company; provided, however, that the preemptive subscription rights of the then existing shareholders shall apply by provision of the Company’s articles of association in connection with any issuance of convertible bonds or other instruments convertible into shares for cash; and

(d) any issuance of shares (including by way of free shares or at a discount), up to an amount of 1.5% of the issued share capital of the Company, to directors, officers, agents or employees of the Company, its direct or indirect subsidiaries, or its affiliates, including without limitation the direct issue of shares upon the exercise of options, rights convertible into shares, or similar instruments convertible or exchangeable into shares issued for the purpose of, or in relation to, compensation or incentive for any such persons or in relation thereto (which the board of directors shall be authorized to issue upon such terms and conditions as it deems fit).

Amendment of the Company’s articles of association requires the approval of shareholders at an extraordinary shareholders’ meeting with a two-thirds majority vote of the shares represented at the meeting.

Dividends

Subject to applicable law, all shares (including shares underlying ADSs) are entitled to participate equally in dividends when, as and if declared by the shareholders at the annual general shareholders’ meeting, out of funds legally available for such purposes.

Dividends may be lawfully declared and paid if the Company's net profits and distributable reserves are sufficient under Luxembourg law. The amount and payment of dividends must be approved by a majority vote at a general shareholders’ meeting, generally, but not necessarily, based on the recommendation of the Company’s board of directors. Under Article 21 of the Company’s articles of association, the board of directors has the power to distribute interim dividends out of profits, share premium or any other available reserves, in accordance with applicable law, in particular in accordance with the conditions set forth in article 461-3 of the Luxembourg Company Law. Such dividend payments must be finally approved by the general shareholders’ meeting. On March 18, 2022 the board of directors announced the proposals to be submitted to the consideration of the annual general shareholders’ meeting, including its proposal on dividends.

103

As provided by Article 21 of the Company’s articles of association, dividends or other distributions declared by the general meeting as well as interim dividends or other distributions declared by the board of directors will be distributed at the times and places determined by the board of directors. The Company will make any and all dividend payments and any other distributions in respect of shares registered in the name of any securities settlement system or operator of such a system or in the name of any financial institution or other professional depositary of securities or any other depositary, whether in cash, shares or other assets, only to such registered holder, or otherwise in accordance with such registered holder’s instructions, and, as provided by Article 21 of the Company’s articles of association, that payment shall release the Company from any and all obligations for such payment.

The Company conducts its operations through subsidiaries and, accordingly, its main source of cash to pay dividends among other possible sources, will be the dividends received from its subsidiaries. For further information, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Structure of the Company—The Company's dividend payments depends on the results of operations and financial condition of its subsidiaries and could be affected by legal, contractual or other limitations or tax changes”. These dividend payments will likely depend on the Company's subsidiaries’ results of operations, financial condition, cash and capital requirements, future growth prospects and other factors deemed significant by their respective boards of directors, as well as on any applicable legal restrictions. For further information, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Countries in Which Ternium Operates—Argentina”.

Under Luxembourg law, claims for dividends will lapse in favor of the Company five years after the date such dividends are declared. However, the Company may elect to pay a declared dividend after such period. Declared and unpaid dividends held by the Company for the account of its shareholders do not bear interest.

Pursuant to Luxembourg law, at least 5% of our net profits per year must be allocated to the creation of a legal reserve until such reserve has reached an amount equal to 10% of our issued share capital. If the legal reserve later falls below the 10% threshold, at least 5% (or such lower amount required to reach the 10% threshold) of net profits again must be allocated toward the reserve. As of December 31, 2021, the Company’s legal reserve represented 10% of its share capital. The legal reserve is not available for distribution.

Voting Rights; Shareholders’ Meetings; Election of Directors

Each share entitles the holder thereof to one vote at the Company’s general shareholders’ meetings. Shareholder action by written consent is not permitted, but proxy voting is permitted. Notices of general shareholders’ meetings are governed by the provisions of Luxembourg law and the Company’s articles of association. Pursuant to applicable Luxembourg law, the Company must give notice of the calling of any general shareholders meeting at least 15 days prior to the date for which the meeting is being called, by publishing the relevant convening notice in the Recueil électronique des sociétés et associations (Luxembourg's electronic official gazette) and in a leading newspaper having general circulation in Luxembourg and by issuing a press release informing of the calling of such meeting. The Company’s articles of association provide that notices for any general shareholders’ meeting shall include such information and shall be given in such form through such means and at such time or times as may be required under applicable Luxembourg law; and, in case the shares of the Company are listed on a regulated market, such notices shall, in addition, satisfy such requirements as are applicable to, and mandatory for, notices of general shareholders’ meetings of issuers such as the Company under the applicable laws, rules and regulations of such regulated market.

No attendance quorum is required at ordinary general shareholders’ meetings and resolutions may be adopted by a simple majority vote of the shares present or represented and voted at the meeting. An extraordinary general shareholders’ meeting may only validly deliberate when at least half of the share capital is present or represented. If the required quorum is not met at an extraordinary general shareholders meeting, a second meeting may be convened in accordance with the Company's articles of association and applicable law and such second extraordinary general shareholders meeting shall validly deliberate regardless of the quorum present or represented. Resolutions on the following matters may only be adopted at extraordinary general shareholders’ meetings: (a) amendment to the articles of association; (b) dissolution and liquidation of the Company; (c) setting of the authorized share capital and granting of authorization to the board of directors to increase the Company’s share capital within the limits of the authorization; (d) decrease of the Company’s share capital; and (e) sale of all or substantially all of the Company’s assets. Such resolutions, in order to be adopted, must be approved by a majority of at least two-thirds of the votes of the shares present or represented. The following matters shall require a unanimous resolution of all the shareholders of the Company: (a) change of the nationality of the Company; and (b) increase of shareholders’ commitments.

104

Cumulative voting is not permitted. The Company’s articles of association do not provide for staggered terms, and directors are elected for a maximum of one year but may be reappointed or removed at any time, with or without cause, by the general shareholders’ meeting, by resolution passed by a simple majority vote of the shares present or represented at the meeting and voted. In the case of a vacancy occurring on the board of directors, the remaining directors shall have the right to temporarily fill such vacancy with a temporary director appointed by resolution adopted with the affirmative vote of a majority of the remaining directors; provided that the next general shareholder’s meeting shall be called upon to ratify such appointment. The term of a temporary director elected to fill a vacancy shall expire at the end of the term of office of the replaced director.

The next Company’s annual general shareholders’ meeting, that will consider, among other matters, Ternium's 2021 consolidated financial statements and annual accounts, is expected to be held on May 3, 2022.

The articles of association provide that annual general shareholders’ meetings shall meet in Luxembourg within six months from the end of the previous financial year at the date, place and hour indicated in the convening notice.

Any shareholder who holds one or more shares of the Company on the fifth calendar day preceding a general shareholders’ meeting (the “Record Date”) shall be admitted to such general shareholders’ meeting. Those shareholders who have sold their shares between the Record Date and the date of the general shareholders’ meeting may not attend or be represented at the meeting.

In the case of shares held through fungible securities accounts, each shareholder may exercise all rights attached to his shares and, in particular, may participate in and vote at shareholders’ meetings of the Company upon presentation of a certificate issued by the financial institution or professional depositary holding the shares, evidencing such deposit and certifying the number of shares recorded in the relevant account on the Record Date. Such certificate must be filed at least five days before the meeting with the Company at its registered address or at the address stated in the convening notice or, in case the shares of the Company are listed on a regulated market, with an agent of the Company located in the country of the listing and designated in the convening notice. In case any such holder wishes to vote by proxy, the holder shall have to present a completed proxy form together with the certificate previously referred to, by the same date and time and at the same addresses. The board of directors and the shareholders at the shareholders’ meeting may, if they deem so advisable, reduce these periods of time for all shareholders and admit all shareholders (or their proxies) who have filed the appropriate documents to the general shareholders’ meeting, irrespective of these time limits.

Holders of ADSs only have those rights that are expressly granted to them in the deposit agreement dated January 31, 2006 among the Company, The BNY Mellon (formerly The Bank of New York), as depositary, and the owners and beneficial owners from time to time of ADSs of the Company. See Item 3. “Key Information-D. Risk Factors-Risks Relating to the Company's ADSs holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders." ADS holders may not attend or directly exercise voting rights in shareholders’ meetings, but holders of record of our ADSs as of the relevant ADS holders’ record date set for any given general shareholders’ meeting are entitled to instruct the Depositary as to the exercise of the voting rights in respect of the shares underlying such holder’s ADSs at such meeting.

Access to Corporate Records

Luxembourg law and the Company’s articles of association do not generally provide for shareholder access to corporate records. Shareholders may inspect the annual accounts and auditors’ reports at the Company’s website https://investors.ternium.com or at its registered office starting from the call to the annual general shareholder’s meeting.

Appraisal Rights

In case the shares of the Company are listed on one or more regulated markets, and in the event the shareholders, in a general meeting, approve any of the following:

•the delisting of the Company’s shares from all regulated markets where the Company’s shares are listed at that time, excluding a delisting made pursuant to an offer to all of the Company’s shareholders made by a business entity subject to common control with the Company, whereby such business entity offers to issue, in exchange for the Company’s shares, shares to be listed on the same regulated market(s) on which the Company’s shares are listed;

105

•a merger in which the Company is not the surviving entity (unless the shares or other equity securities of such entity are listed on the New York or London stock exchanges);

•a sale, lease, exchange or other disposition of all or substantially all of the Company’s assets;

•an amendment to the Company’s articles of association that has the effect of materially changing its corporate purpose;

•the relocation of the Company’s domicile outside the Grand Duchy of Luxembourg; or

•amendments to the Company’s articles of association that restrict the rights of its shareholders (excluding any amendments in relation with, or to, the authorized share capital and/or the waiver or suppression of any preferential subscription rights relating thereto).

Dissenting or absent shareholders have the right to have their shares repurchased by the Company at (i) the average market value of the shares over the 90 calendar days preceding the applicable general shareholders’ meeting or (ii) in the event that the Company’s shares are not traded on any regulated market, the amount that results from applying the proportion of the Company’s equity that the shares being sold represent over the Company’s net worth as determined in its last consolidated financial statements approved by the shareholders or in its last interim consolidated financial statements approved by the board of directors, whichever is more recent. Shareholders who voted in favor of the relevant resolution are not entitled to exercise this right.

Dissenting or absent shareholders must present their claim within one month following the date of the applicable general shareholders’ meeting and supply the Company with evidence of their shareholding at the time of such meeting. The Company must (to the extent permitted by applicable laws and regulations and in compliance therewith) repurchase its shares within six months following the date of the applicable general shareholders’ meeting. If delisting from one or more, but not all, of the regulated markets where the Company’s shares are listed is approved by the shareholders’ meeting, only dissenting or absent shareholders with shares held through participants in the local clearing system for that market or those markets can exercise this appraisal right if:

•they held the shares as of the date of the announcement by the Company of its intention to delist or as of the date of publication of the first convening notice for the general shareholders’ meeting that approved the delisting;

•they present their claim within one month following the date of the general shareholders’ meeting and supply evidence of their shareholding as of the date of the Company’s announcement or the publication of the first convening notice to the meeting; and

•the delisting is not being made pursuant to an offer to all of the Company’s shareholders made by a business entity subject to common control with the Company, whereby such business entity offers to issue, in exchange for the Company’s shares, shares to be listed on the same regulated market(s) on which such dissenting or absent shareholders hold their shares through participants in the local clearing system for that market or markets.

In the event a shareholder exercises its appraisal rights, applicable Luxembourg law provisions shall apply. Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders, including appraisal rights. See Item 3.D. “Key Information – Risk Factors – Risks Relating to the Company's ADSs – Holders of ADSs may not be able to exercise, or may encounter difficulties in the exercise of, certain rights afforded to shareholders”.

Distribution of Assets on Winding-up

In the event of the Company’s liquidation, dissolution or winding-up, the net assets remaining after allowing for the payment of all debts, charges and expenses shall be paid out to holders of the Company’s shares in proportion to their respective holdings.

Transferability and Form

The Company’s articles of association do not contain any redemption or sinking fund provisions, nor do they impose any restrictions on the transfer of shares. The shares are issuable in registered form only.

106

The ownership of registered shares is evidenced by the inscription of the name of the shareholder, the number of shares held by such shareholder and the amount paid on each share in the Company’s share register. In addition, the Company’s shares may be held through fungible securities accounts with financial institutions or other professional depositaries. Shares held through fungible securities accounts have the same rights and obligations as shares recorded in the Company’s shareholders’ register.

Shares held through fungible securities accounts may be transferred in accordance with customary procedures for the transfer of securities in book-entry form. Shares that are not held through fungible securities accounts may be transferred by a written statement of transfer signed by both the transferor and the transferee or their respective duly appointed attorney-in-fact and recorded in the Company’s share register. The transfer of shares may also be made in accordance with the provisions of Article 1690 of the Luxembourg Civil Code. As evidence of the transfer of registered shares, the Company may also accept any correspondence or other documents evidencing the agreement between transferor and transferee as to the transfer of registered shares.

Repurchase of Company Shares

The Company may repurchase its own shares in the cases and subject to the conditions set by the Luxembourg Company Law and, in the case of acquisitions of shares or ADSs made through the NYSE, with any applicable laws and regulations of such market. See Item 16.E. “Purchases of Equity Securities by the Issuer and Affiliated Purchasers” for further information on the authorization to the Company or its subsidiaries to repurchase the Company’s shares, including shares represented by ADSs.

Limitation on Securities Ownership

There are no limitations currently imposed by Luxembourg law or the articles of association on the rights of the Company's non-resident or foreign shareholders to hold or vote the Company’s shares.

Change in Control

None of our outstanding securities has any special control rights. The Company’s articles of association do not contain any provision that would have the effect of delaying, deferring or preventing a change in control of the Company and that would operate only with respect to a merger, acquisition or corporate restructuring involving the Company or any of its subsidiaries. In addition, the Company does not know of any significant agreements or other arrangements to which the Company is a party and which take effect, alter or terminate in the event of a change of control of the Company. There are no agreements between the Company and members of its board of directors or employees providing for compensation if they resign or are made redundant without reason, or if their employment ceases following a change in control of the Company.

There are no rights associated with the Company’s shares other than those described above.

C.     Material Contracts

For a summary of any material contract entered into by us outside of the ordinary course of business during the last two years, see Item 4. “Information on the Company—B. Business Overview—Raw Materials, Slabs, Energy and Other Inputs.”

D.     Exchange Controls

Many of the countries which are important markets for us or in which we have substantial assets have a history of substantial government intervention in currency markets, volatile exchange rates and government-imposed currency controls. These include Mexico, Brazil and Argentina. For additional information regarding Ternium’s ability to hedge against exchange rate fluctuations, see Item 3. “Key Information—D. Risk Factors—Risks Relating to Ternium's Business—Changes in exchange rates or any limitation in the ability of the Ternium companies to hedge against exchange rate fluctuations could adversely affect Ternium’s business and results.”

Mexico

Historically, the Mexican economy has suffered balance of payment deficits and shortages in foreign exchange reserves. While the Mexican government does not currently restrict the ability of Mexican or foreign persons or

107

entities to convert Mexican pesos to U.S. dollars and the terms of USMCA—to which Mexico is a signatory—generally prohibit exchange controls, the Mexican government could institute a restrictive exchange control policy in the future.

Brazil

Before March 2005, there were two legal foreign exchange markets in Brazil, the commercial market and the floating market. The difference between these two markets was the type of transaction that could be performed through each market.

On March 4, 2005, the Brazilian National Monetary Council ("CMN"), through CMN Resolution N. 3,265 (revoked and replaced by CMN Resolution N. 3,568, of May 29, 2008), introduced a single foreign exchange market and abolished the legal differences between the referred Commercial and Floating Markets. Among the modifications to foreign exchange market rules is a greater freedom to remit funds abroad through the foreign exchange market. On the other hand, the so-called “CC5-Accounts”, which are bank accounts in Brazilian reais held in Brazil by foreign entities, may no longer be used to transfer funds on behalf of third parties.

On March 24, 2010, the CMN approved Resolution No. 3,844, adopting a series of measures to consolidate and simplify the Brazilian foreign exchange regulations. These changes are expected to reduce the effective cost of foreign exchange transactions and the related administrative expenses for both the public and private sectors as well as to provide more legal certainty to the parties to such transaction.

In the past, the Brazilian central bank has intervened occasionally to control unstable movements in foreign exchange rates. We cannot predict whether the central bank or the Brazilian government will continue to let the real float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. The real may depreciate or appreciate against the U.S. dollar.

Argentina

During 2021, the Argentine peso was subject to a depreciation of approximately 18% against the US dollar. In the past, the Argentine authorities took several measures to reduce volatility of the ARS/$ exchange rate and implemented formal and informal restrictions on capital inflows into Argentina and capital outflows from Argentina. Certain foreign exchange restrictions that had been gradually lifted in December 2015 were reinstated in 2019 and have continued to tighten over the past two years. The Argentine government tightened controls on the flows of capital by requiring Argentine companies to repatriate all export proceeds from sales of goods and services (including U.S. dollars received through advance payment and pre-financing facilities) and convert such proceeds into Argentine pesos, restricting the purchase of foreign currency for saving purposes, and limiting or conditioning the ability of Argentine companies to access the foreign exchange market.

As of December 31, 2021, Ternium Argentina’s cash and cash equivalents and other investments, held in Argentine financial institutions, amounted to $965 million. For a breakdown of Ternium Argentina’s cash and cash equivalents and other investments as of December 31, 2021, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report. Since 2019, access to the Argentine foreign exchange market for various purposes (including to repay foreign financial indebtedness, to pay services to related parties or to distribute dividends abroad) has been severely limited. Prior approval from the Argentine central bank, which is rarely (if ever) granted, is required to purchase foreign currency for payment of dividends to foreign shareholders and for other payments to affiliates abroad. Ternium Argentina has requested prior approval to the Argentine central bank for certain payments of services to affiliates abroad and, as of the date of this annual report, no such approvals have been granted.

Foreign exchange restrictions have also begun to affect imports of goods and services. Some of Ternium Argentina’s key steelmaking inputs, including iron ore and metallurgical coal, are imported into Argentina from other markets. In March 2022, the Argentine government imposed further restrictions to access the foreign exchange market for payment of imports. If such restrictions are maintained, or are further tightened, Ternium Argentina could be restricted from making payment of imports for key steelmaking inputs which would adversely affect its operations, or would need to resort to alternative, more expensive arrangements, which would affect its results of operations.

As an environment of volatility and uncertainty remains in place as of the date of this annual report, there is no assurance that the Argentine central bank or other Argentine authority will not further tighten exchange controls or

108

impose new foreign exchange restrictions in the future. Any such additional controls and restrictions could further impair Ternium Argentina’s ability to access the official foreign exchange market, expose Ternium to losses resulting from fluctuations in the exchange rate, affect Ternium’s ability to finance its investments in Argentina and impair Ternium Argentina’s ability to make payments to foreign suppliers or creditors (which could disrupt Ternium Argentina’s operations), pay dividends or royalties abroad, or fund investments or other activities offshore.

For additional information regarding factors affecting the Argentine economy, see Item 3. “Key Information—D. Risk Factors—Risks Relating to the Countries in Which Ternium Operates—Argentina.”; for additional information on current foreign exchange restrictions in Argentina, see note 30 “Foreign exchange restrictions in Argentina” to our consolidated financial statements included in this annual report.

Colombia

Under Colombian foreign exchange regulations, payments in foreign currency related to certain foreign exchange transactions must be conducted through the commercial exchange market, by means of an authorized financial intermediary, and the payment must be declared to the Colombian central bank. This mechanism applies to payments in connection with, among others, imports and exports of goods, foreign loans and related financing costs, investment of foreign capital and the remittances of profits thereon, investment in foreign securities and assets and endorsements and guarantees in foreign currency. Transactions through the commercial exchange market are made at market rates freely negotiated with the authorized intermediaries.

E.     Taxation

The following discussion of the material Luxembourg and U.S. federal income tax consequences of an investment in our shares and ADSs is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This discussion does not address all possible tax consequences relating to an investment in our shares or ADSs, including the tax consequences under U.S. state and local tax laws.

 Grand Duchy of Luxembourg

This section describes the material Luxembourg tax consequences of owning or disposing of shares or ADSs.

It is not intended to be, nor should it be construed to be, legal or tax advice. You should, therefore, consult your own tax advisor regarding local or foreign tax consequences, including Luxembourg tax consequences of owning and disposing of shares or ADSs in your particular circumstances.

As used herein, a “Luxembourg individual” means an individual resident in Luxembourg who is subject to personal income tax (impôt sur le revenu) on his or her worldwide income from Luxembourg or foreign sources, and a “Luxembourg corporate holder” means a company (that is, a fully taxable collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law) resident in Luxembourg subject to Luxembourg corporate income tax (impôt sur le revenu des collectivités) and Luxembourg municipal business tax (impôt commercial communal, on its worldwide income from Luxembourg or foreign sources). For the purposes of this summary, Luxembourg individuals and Luxembourg corporate holders are collectively referred to as “Luxembourg Holders”. A “non-Luxembourg Holder” means any investor in shares or ADSs of the Company other than a Luxembourg Holder.

Corporate Reorganization

The Company was established as a Luxembourg société anonyme holding under Luxembourg’s 1929 holding company regime. Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929 regime (including the Company) were exempt from Luxembourg corporate income tax, Luxembourg municipal business tax, Luxembourg net wealth tax and Luxembourg withholding tax over dividends distributed to shareholders.

On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, effective as from that date, the Company is subject to all applicable Luxembourg taxes (including, among others, Luxembourg corporate income tax on its worldwide income).

In light of the impending termination of Luxembourg’s 1929 holding company regime, in the fourth quarter of 2010, the Company carried out a multi-step corporate reorganization, which included, among other transactions, the

109

contribution of most of the Company’s assets and liabilities to a wholly-owned, newly-incorporated Luxembourg subsidiary, and the restructuring of indirect holdings in certain subsidiaries.

The first phase of the corporate reorganization was completed in December 2010 and resulted in a non-taxable revaluation of the accounting value (under Luxembourg GAAP) of the Company's assets. The second phase of the reorganization was completed in 2011.

Following the completion of the first phase of the corporate reorganization, and upon its conversion into an ordinary Luxembourg holding company, the Company recorded a special reserve in its tax balance sheet for an amount of $7.9 billion ($3.4 billion –net of accumulated fiscal losses- remaining at 2021 year-end). Dividend distributions will be charged to the special reserve and therefore should not be subject to Luxembourg withholding tax (up-to- the remaining amount of such special reserve).

Tax regime applicable to realized capital gains

Luxembourg Holders

Luxembourg resident individual holders

Capital gains realized by Luxembourg resident individuals who do not hold their shares or ADSs as part of a trade or business (i.e. capital gains on private assets) and who hold (together, directly or indirectly, with their spouse or civil partner and underage children) no more than 10% of the share capital of the Company at any time during the five-year period preceding the disposition will only be taxable (at a progressive rate) if they are realized on a sale of shares or ADSs that takes place before their acquisition or within the first six months following their acquisition (i.e. speculative gain). After the six-months period, capital gains are not taxed unless the resident individual holds (together, directly or indirectly, with his or her spouse or civil partner and underage children) more than 10% of the share capital of the Company at any time during the five-year period preceding the disposition.

If such shares or ADSs are held as part of a commercial or industrial business, capital gains would be taxable in the same manner as income from such business.

Capital gains realized by Luxembourg resident individuals holding (alone or together with the resident’s spouse or civil partner and underage children) directly or indirectly more than 10% of the capital of the Company at any time during the five years prior to the sale, (or if the Luxembourg resident individuals have received the shares for no consideration within the last five years and the former holder held at least 10% in the capital of the company at any moment during said five years) will be taxable at half of the individual’s applicable global tax rate (as determined progressively), if a holding period of six months following their acquisition elapsed (21% for 2021). Within the six month period, progressive income tax rates apply (ranging from 0 to 42%* in 2021).

*A 7% surcharge for the Employment Fund applies on the income tax due. The surcharge for the Employment Fund amounts to 9% for taxpayer in tax class 1 or 1a with taxable income exceeding EUR 150,000 (EUR 300,000 for taxpayer in tax class 2).

Luxembourg resident corporate holders

Capital gains, including currency exchange gains realized upon the disposal of shares or ADSs by a fully taxable resident corporate holder, will in principle be subject to Luxembourg corporate income tax and Luxembourg municipal business tax. The combined applicable rate (including an unemployment fund contribution) for a corporate holder established in Luxembourg City is 24.94% for the fiscal year ending 2021. An exemption from such taxes may be available to the Luxembourg resident corporate holder pursuant to Article 1 of the Grand Ducal Decree dated December 21, 2001 as amended, in combination with article 166 of the Luxembourg Income Tax Law subject to the fulfillment of the conditions set forth therein.

Non-Luxembourg Holders

Non-Luxembourg individual holders

An individual who is a non-Luxembourg Holder of shares or ADSs (and who does not have a permanent establishment, a permanent representative or a fixed place of business in Luxembourg) will only be subject to

110

Luxembourg taxation on capital gains arising upon disposal of such shares or ADSs if such holder has (alone or together with his or her spouse, civil partner and underage children) directly or indirectly held more than 10% of the capital of the Company at any time during the past five years preceding the disposal, and either (i) such non-Luxembourg Holder has been a resident of Luxembourg for tax purposes for at least 15 years and has become a non-resident within the last five years preceding the realization of the gain, subject to any applicable tax treaty, or (ii) the disposal of shares or ADSs occurs within six months from their acquisition (or prior to their actual acquisition), subject, however, to any applicable tax treaty.

Non-Luxembourg corporate holders

A corporate non-Luxembourg Holder (that is, a collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law), which has a permanent establishment, a permanent representative or a fixed place of business in Luxembourg to which shares or ADSs are attributable, will bear Luxembourg corporate income tax and Luxembourg municipal business tax on a gain realized on a disposal of such shares or ADSs as set forth above for a Luxembourg corporate holder. However, capital gains, including currency exchange gains, realized on the sale of the shares or ADSs may benefit from the full exemption provided for by Article 1 of the Grand Ducal Decree dated December 21, 2001 as amended, in combination with Article 166 of the Luxembourg Income Tax Law subject in each case to fulfillment of the conditions set out therein.

A corporate non-Luxembourg Holder, which has no permanent establishment, permanent representative or fixed place of business in Luxembourg to which the shares or ADSs are attributable, will bear non-resident capital gains tax on a gain realized on a disposal of such shares or ADSs under the same conditions applicable to an individual non-Luxembourg Holder, as set out above.

Tax regime applicable to distributions

Withholding tax

Distributions to holders are in principle subject to a 15% Luxembourg withholding tax computed on the gross amount distributed. The rate of the withholding tax may be reduced pursuant to double tax treaty existing between Luxembourg and the country of residence of the relevant holder, subject to the fulfillment of the conditions set forth therein. However, distributions imputed for tax purposes to the special reserve (please see above paragraph “corporate reorganization”) should be exempt from Luxembourg withholding tax under the current tax law.

Nevertheless, a withholding tax exemption may apply if the distribution is made to (as far as relevant in the case at hand):

•a Luxembourg resident corporate holder (that is, a fully taxable collectivité within the meaning of article 159 of the Luxembourg Income Tax Law);

•the Luxembourg State, a municipality, or a public body;

•an undertaking of collective character which is resident of a Member State of the European Union and is referred to by article 2 of the EU Council Directive of November 30, 2011 concerning the common fiscal regime applicable to parent and subsidiary companies of different member states (2011/96/UE) as amended, (subject to the general anti-abuse rule provided for by Council Directive 2015/121/EU as implemented into Luxembourg law);

•a capital company or a cooperative company resident in Norway, Iceland or Liechtenstein and subject to a tax comparable to corporate income tax as provided by the Luxembourg Income Tax Law;

•a Luxembourg permanent establishment of one of the above-mentioned categories;

•a capital company resident in Switzerland which is subject to corporate income tax in Switzerland without benefiting from an exemption; and

•an undertaking with a collective character subject to a tax comparable to corporate income tax as provided by the Luxembourg Income Tax Law which is resident in a country that has concluded a double tax treaty with Luxembourg.

provided each time that at the date of payment, the holder holds or commits to hold directly (or through a company regarded as tax transparent from a Luxembourg tax perspective), during an uninterrupted period of at least twelve months, shares or ADSs representing at least 10% of the share capital of the Company or acquired for an acquisition price of at least EUR 1,200,000.

Luxembourg Holders

111

With the exception of Luxembourg corporate holders benefiting from the application of Luxembourg participation exemption as per Article 166 of Luxembourg Income Tax Law (provided that the relevant requirements are met), Luxembourg individual holders, and Luxembourg corporate holders fully subject to Luxembourg corporate tax, must include the distributions received on the shares or ADSs in their taxable income, 50% of the amount of such dividends being exempt from tax. The applicable withholding tax can, under certain conditions, entitle the relevant Luxembourg Holder to a tax credit.

Non Luxembourg Holders

Non-Luxembourg Holders of shares or ADSs and who do not have a permanent establishment, a permanent representative or a fixed place of business in Luxembourg to which the shares or ADSs would be attributable are not liable for any Luxembourg tax on dividends received on the shares or ADSs, other than a potential withholding tax as described above.

Net wealth tax

Luxembourg Holders

Luxembourg net wealth tax will not be levied on a Luxembourg Holder with respect to the shares or ADSs held unless (i) the Luxembourg Holder is a legal entity subject to net wealth tax in Luxembourg; or (ii) the shares or ADSs are attributable to an enterprise or part thereof which is carried on through a permanent establishment, a fixed place of business or a permanent representative in Luxembourg.

Net wealth tax is levied annually at the rate of 0.5% for taxable net wealth not exceeding EUR 500,000,000 and at a rate of 0.05% for the net wealth exceeding EUR 500,000,000, of enterprises resident in Luxembourg, as determined for net wealth tax purposes. The shares or ADSs may be exempt from net wealth tax subject to the conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934 on the valuation of assets (Bewertungsgesetz), as amended.

A minimum net wealth tax charge applies as of January 1, 2016 for all corporate entities having their statutory seat or central administration in Luxembourg. Subject to certain conditions, the amount of minimum net wealth tax may vary.

Non-Luxembourg Holders

Luxembourg net wealth tax will not be levied on a non-Luxembourg Holder with respect to the shares or ADSs held unless the shares or ADSs are attributable to an enterprise or part thereof which is carried on through a permanent establishment or a permanent representative in Luxembourg. The shares or ADSs may be exempt from net wealth tax subject to the conditions set forth by Paragraph 60 of the Luxembourg Law of October 16, 1934 on the valuation of assets (Bewertungsgesetz), as amended.

Stamp and registration taxes

No registration tax or stamp duty will be payable by a holder of shares or ADSs in Luxembourg solely upon the disposal of shares or ADSs by sale or exchange.

Estate and gift taxes

No estate or inheritance tax is levied on the transfer of shares or ADSs upon the death of a holder of shares or ADSs in cases where the deceased was not a resident of Luxembourg for inheritance tax purposes and no gift tax is levied upon a gift of shares or ADSs if the gift is not passed before a Luxembourg notary or recorded in a deed registered in Luxembourg.

Where a holder of shares or ADSs is a resident of Luxembourg for tax purposes at the time of the holder's death, the shares or ADSs are included in its taxable estate for inheritance tax or estate tax purposes.

U.S. federal income taxation

112

This section describes the material U.S. federal income tax consequences to a U.S. holder (as defined below) of owning shares or ADSs It applies to you only if you hold your shares or ADSs as capital assets for U.S. federal income tax purposes. This discussion addresses only U.S. federal income taxation and does not discuss all of the tax consequences that may be relevant to you in light of your individual circumstances, including foreign, state or local tax consequences, estate and gift tax consequences, and tax consequences arising under the Medicare contribution tax on net investment income or the alternative minimum tax. This section does not apply to you if you are a member of a special class of holders subject to special rules, including:

•a dealer in securities,

•a bank,

•a trader in securities that elects to use a mark-to-market method of accounting for securities holdings,

•a tax-exempt organization,

•a person who invests through a pass-through entity, including a partnership,

•a life insurance company,

•a former citizen or long-term resident of the United States,

•a person that actually or constructively owns 10% or more of the combined voting power of our voting stock or of the total value of our stock (including ADSs),

•a person that holds shares or ADSs as part of a straddle or a hedging or conversion transaction for U.S. federal income tax purposes,

•a person that purchases or sells shares or ADSs as part of a wash sale for U.S. federal income tax purposes, or

•a person whose functional currency is not the U.S. dollar.

This section is based on the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations, published rulings and court decisions, all as currently in effect, as well as on the Convention between the Government of the Grand Duchy of Luxembourg and the Government of the United States of America for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income and Capital (the “Treaty”). These laws are subject to change, possibly on a retroactive basis. In addition, this section is based in part upon the assumption that each obligation in the ADS deposit agreement and any related agreement will be performed in accordance with its terms.

If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the shares or ADSs, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Each such partner holding the shares or ADSs is urged to consult his, her or its own tax advisor.

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

•an individual citizen or resident of the United States,

•a domestic corporation (or an entity treated as a domestic corporation),

•an estate whose income is subject to U.S. federal income tax regardless of its source, or

•a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust or (ii) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, if you hold ADRs evidencing ADSs, you will be treated as the owner of the shares represented by those ADSs. Exchanges of shares for ADRs, and ADRs for shares, generally will not be subject to U.S. federal income tax.

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

You should consult your own tax advisor regarding the U.S. federal, state and local and other tax consequences of owning and disposing of shares or ADSs in your particular circumstances.

113

Taxation of distributions

Under the U.S. federal income tax laws, if you are a U.S. holder, the gross amount of any distribution we pay out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes), other than certain pro-rata distributions of our shares, including the amount of any Luxembourg tax withheld, will be treated as a dividend that is subject to U.S. federal income taxation. If you are a non-corporate U.S. holder, dividends paid to you that constitute qualified dividend income will be taxable to you at the preferential rates applicable to long-term capital gains provided that you hold shares or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements. Dividends we pay with respect to the shares or ADSs generally will be qualified dividend income, provided that, in the year that you receive the dividend, we are eligible for the benefits of the Treaty. We believe that we are currently eligible for the benefits of the Treaty and therefore expect that dividends on the shares or ADSs will be qualified dividend income, but there can be no assurance that we will continue to be eligible for the benefits of the Treaty.

You must generally include any Luxembourg tax withheld from the dividend payment in this gross amount even though you do not in fact receive it. The dividend is taxable to you when you receive it, or, in the case of ADSs, when the depositary receives the dividend, actually or constructively. The dividend will not be eligible for the dividends-received deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations. Distributions in excess of current and accumulated earnings and profits, as determined for U.S. federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in the shares or ADSs and thereafter as capital gain. However, we do not expect to calculate earnings and profits in accordance with U.S. federal income tax principles. Therefore, you should expect that a distribution will generally be treated as a dividend (as discussed above).

Dividends will generally be income from sources outside the United States and generally will be “passive” income for purposes of computing the foreign tax credit allowable to you.

Subject to certain limitations, the Luxembourg tax withheld in accordance with the Treaty and paid over to Luxembourg will be creditable or deductible against your U.S. federal income tax liability. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the preferential tax rates. To the extent a refund of the tax withheld is available to you under Luxembourg law or under the Treaty, the amount of tax withheld that is refundable will not be eligible for credit against your U.S. federal income tax liability.

In certain circumstances, if you have held ADSs for less than a specified minimum period during which you are not protected from risk of loss, or are obligated to make payments related to the dividends, you will not be allowed a foreign tax credit for foreign taxes imposed on dividends that we pay.

The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of capital gains

If you are a U.S. holder and you sell or otherwise dispose of your shares or ADSs, you will recognize capital gain or loss for U.S. federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you realize and your tax basis, determined in U.S. dollars, in your shares or ADSs. Capital gain of a non-corporate U.S. holder is generally taxed at preferential rates where the property is held for more than one year. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes. The deductibility of capital losses is subject to limitations.

    Additional U.S. Federal Income Tax Considerations

PFIC Rules: Based on the Company’s current and expected income and assets, we believe that the shares or ADSs should not currently be treated as stock of a PFIC for U.S. federal income tax purposes and we do not expect to become a PFIC in the foreseeable future. However this conclusion is a factual determination that is made annually and thus may be subject to change. It is therefore possible that we could become a PFIC in a future taxable year. If we were to be treated as a PFIC, gains realized on the sale or other disposition of your shares or ADSs would in general not be treated as capital gains. Furthermore, if you are a U.S. holder, unless you are permitted to elect and you do elect to be taxed annually on a mark-to-market basis with respect to the shares or ADSs, upon sale or disposition of shares or

114

ADSs you would generally be treated as if you had realized such gain and certain “excess distributions” ratably over your holding period for the shares or ADSs and would be taxed at the highest tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax attributable to each such year. With certain exceptions, your shares or ADSs will be treated as stock in a PFIC if we were a PFIC at any time during your holding period in your shares or ADSs. Dividends that you receive from us will not be eligible for the special tax rates applicable to qualified dividend income if we are a PFIC (or are treated as a PFIC with respect to you) either in the taxable year of the distribution or the preceding taxable year, but instead will be taxable at rates applicable to ordinary income and subject to the excess distribution regime described above.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

115

The multinational nature of our transactions, operations and customer base expose us to a variety of risks, including the effects of changes in interest rates, foreign currency exchange rates and commodity prices. We selectively manage these exposures through the use of derivative instruments to mitigate market risk and interest rate costs. In addition, we may use derivative instruments embedded in investment instruments, in compliance with Ternium’s policy for financial investments. We do not use derivative financial instruments for other purposes. In addition, in the ordinary course of business we also face risks with respect to financial instruments that are either non-financial or non-quantifiable. Such risks principally include country risk and credit risk and are not presented in the following analysis. For additional information about our financial risk management, see note 28 to the consolidated financial statements included in this annual report.

The following tables provide a breakdown of Ternium’s debt instruments as of December 31, 2021, by type of interest rate fixing mechanism and year of maturity. The following information should be read together with note 28 “Financial Risk Management” to the consolidated financial statements included in this annual report.

At December 31, 2021	Expected maturity in the year ending December 31,
In $ million	2022	2023	2024	2025	Thereafter	Total
Non-current Debt
Floating Rate		125	522	9	—	656

Floating Rate	648	—	—	—	—	648
Total (1) (2)	823	125	522	9	—	1,479

(1)Borrowings are primarily bank borrowings. For further information, see Item 5. “Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Principal Sources of Funding—Financial Liabilities.”

(2)As most borrowings incorporate floating rates that approximate market rates and the contractual repricing occurs mostly every one, three or six months, the fair value of the borrowings approximates their carrying amount and it is not disclosed separately.

Management maintains sufficient cash and marketable securities and credit facilities to finance normal operations. Management monitors rolling forecasts of the group’s liquidity reserve on the basis of expected cash flow. The weighted average interest rate of Ternium’s debt was 1.45% at December 31, 2021. This figure incorporates instruments denominated mainly in U.S. dollars, does not include the effect of derivative financial instruments and was calculated using the rates set for each instrument in its corresponding currency and weighted using the dollar-equivalent outstanding principal amount of said instruments as of December 31, 2021.

Interest Rate Exposure Risk

Ternium manages its exposure to interest rate volatility through its financing alternatives and hedging instruments. Borrowings with floating rates expose the Company to the risk of increased interest expense in the event of higher market interest rates, while borrowings with fixed rates expose the Company to variations in the instruments’ fair value. The Company’s interest-rate risk mainly arises from long-term borrowings that bear floating-rate interest. Ternium’s total floating interest rate debt amounted to $1.3 billion (88% of total borrowings) for the year ended December 31, 2021. The interest rate on $6.3 million of this debt is fixed through swaps, as described below.

Interest Rate Derivative Contracts

116

During 2012 and 2013, Tenigal entered into several interest rate forward starting swap agreements that fix the interest rate to be paid over an aggregate amount of $100 million, at an average rate of 1.92%. These agreements became effective in July 2014, will terminate in July 2022 and have been accounted for as cash flow hedges. As of December 31, 2021, the after-tax cash flow hedge reserve related to these agreements amounted to negative $0.04 million.

Foreign Exchange Exposure Risk

Ternium operates and sells its products in different countries, and as a result is exposed to foreign exchange rate volatility. Ternium’s subsidiaries may use derivative contracts in order to hedge their exposure to exchange rate risk derived from their trade and financial operations. A significant portion of Ternium’s business is carried out in currencies other than the U.S. dollar, Ternium’s reporting currency. As a result of this foreign currency exposure, exchange rate fluctuations impact Ternium’s results as reported in its income statement and statement of comprehensive income in the form of both translation and transaction risk. Translation risk is the risk that Ternium’s consolidated financial statements for a particular period or as of a certain date may be affected by changes in the prevailing rates of the various functional currencies of the reporting subsidiaries against the U.S. dollar. Transaction risk is the risk that the value of transactions executed in currencies other than the subsidiary’s functional currency may vary according to currency fluctuations.

Ternium’s policy is to minimize the impact of fluctuations in the value of positions in currencies other than U.S. dollar with respect to the U.S. dollar, with the exception of the currencies of countries where it has operations in Latin America, in which Ternium may, from time to time, choose not to hedge operational short exposures to such currencies. Ternium’s subsidiaries monitor their net operating cash flows in currencies other than the U.S. dollar, and analyse potential hedging strategies according to market conditions. This hedging can be carried out by netting operational positions or by using financial derivatives. However, regulatory or legal restrictions in the countries in which Ternium’s subsidiaries operate could limit the extent to which the Company can implement its hedging policy.

The following table shows a breakdown of Ternium’s assessed financial position exposure to currency risk as of December 31, 2021.

U.S. dollars exposure to:	$ million
E.U. euro (EUR)	(78)
Argentine peso (ARS)	297
Mexican peso (MXN)	(1,255)
Brazilian real (BRL)	66
Colombian peso (COP)	(52)
Other currencies	(1)

We estimate that for each 1% depreciation of the Mexican peso against the U.S. dollar, we would have incurred a pre-tax gain of $12.5 million and $5.9 million for the years 2021 and 2020, respectively; We estimate that for each 1% depreciation of the Argentine peso against the U.S. dollar, we would have incurred a pre-tax loss of $3.2 million and $1.0 million for the years 2021 and 2020, respectively; for each 1% depreciation of the Brazilian real against the U.S. dollar, we would have incurred a pre-tax loss of $0.5 million and $1.1 million for the years 2021 and 2020, respectively; and for each 1% depreciation of the Colombian peso against the U.S. dollar, we would have incurred a pre-tax gain of $0.5 and $0.2 million for the years 2021 and 2020, respectively.

We estimate that for each 1% simultaneous depreciation of the Mexican peso, Argentine peso, Brazilian real and Colombian peso against the U.S. dollar with all other variables held constant, total pre-tax income for 2021 would have been $9.4 million higher ($4.0 million higher for 2020), as a result of net foreign exchange gains/losses on translation of U.S. dollar-denominated financial position, mainly trade receivables, lease liabilities, trade payables, lease liabilities, borrowings and other liabilities.

Considering the same variation of the currencies against the U.S. dollar of all net investments in non-U.S. dollar operations in 2021 (which amounted to $681.7 million), the currency translation adjustment included in total equity would have been $6.7 million lower, arising mainly from the adjustment on translation of the equity related to the

117

Brazilian real during the year 2021. For further information on the impact of currency translation adjustments on Usiminas, see Item 5. “Operating and Financial Review and Prospects—Overview.”

Foreign Exchange Derivative Contracts

During 2021, 2020 and 2019, Ternium Argentina entered into non-deliverable forward agreements in order to manage the exposure resulting from financial assets and liabilities denominated in Argentine pesos. As of December 31, 2021, the notional amount on these agreements amounted to $100.0 million.

During 2021, 2020 and 2019, Ternium Colombia entered into non-deliverable forward agreements to manage the exposure of certain actual and future trade receivables denominated in Colombian pesos. As of December 31, 2021, the notional amount on these agreements amounted to $87.8 million.

During 2021, 2020 and 2019, Ternium Mexico entered into forward agreements in order to manage the exposure resulting from certain commitments denominated in E.U. euros related to its investment plan in Pesquería and other standard liabilities in E.U. euros. As of December 31, 2021, the aggregate notional amount on these agreements amounted to $44.0 million.

During 2021, 2020 and 2019, Ternium Investments entered into several forward agreements in order to manage the exchange rate exposure generated by the consolidated financial position in E.U. euros. As of December 31, 2021, the notional amount on these agreements amounted to $12.8 million. Also, during 2021 and 2020, Ternium Investments entered into non-deliverable forward agreements to manage the exchange rate exposure generated by actual and future trade receivables denominated in Colombian pesos related to the commissioning of the plant and the business of its subsidiary, Ternium del Atlántico. As of December 31, 2021, there is no notional amount in Colombian pesos.

The consolidated net fair value of these exchange rate derivative contracts as of December 31, 2021, was $2.6 million. For further information on our foreign exchange contracts see note 21 to the consolidated financial statements included in this annual report.

Commodities Exposure Risk

In the ordinary course of its operations, Ternium’s subsidiaries purchase raw materials, such as iron ore and coal, slabs, and other commodities, including electricity and natural gas. Commodity prices are generally volatile as a result of several factors, including those affecting supply and demand, political, social and economic conditions, and other circumstances. Ternium monitors its exposure to commodity price volatility on a regular basis and applies customary commodity price risk management strategies. During 2021, 2020 and 2019, Ternium did not hedge any commodity position.

D.    American Depositary Shares

According to the Company's deposit agreement, holders of ADSs may have to pay to the Depositary, either directly or indirectly, fees or charges up to the amounts set forth below:

•A fee of $5.00 (or less) per 100 ADSs (or portion of 100 ADSs) for any issuance of ADSs, including issuances resulting from a distribution of shares or rights or other property; and cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates.

•A fee of $0.02 (or less) per ADS for any cash distribution to ADS registered holders, excluding cash dividend.

•Any charges for taxes and other governmental charges that the Depositary or the custodian may be required to pay on any ADS or share underlying an ADS (e.g., share transfer taxes, stamp duty or withholding taxes); and any charges incurred by the Depositary or its agents for servicing the deposited securities.

•Registration or transfer fees for transfer and registration of shares on our share register to or from the name of the Depositary or its agent when you deposit or withdraw shares.

•Expenses of the Depositary for cable, telex and facsimile transmissions (when expressly provided in the deposit agreement); and conversion of foreign currency.

•A fee equivalent to the fee that would be payable if securities distributed to ADS holders had been shares and the shares had been deposited for issuance of ADSs for distribution of securities distributed to holders of deposited securities which are distributed by the Depositary to ADS registered holders.

•As necessary, charges for any costs incurred by the Depositary or its agents for servicing the deposited securities.

The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for depositary services by deductions from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The Depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

Under the deposit agreement with the Depositary, the Depositary is not liable to holders of ADSs, except that the Depositary agrees to perform its obligations specifically set forth therein without gross negligence and willful misconduct.

Fees payable by the Depositary to the Company

Fees paid in 2021. In 2021, the Company received no fees from BNY Mellon in connection with the Company's ADS Program.

Fees to be paid in the future. In the event the Company’s shares are listed in a non-U.S. stock exchange (in addition to the NYSE) allowing for cross-border trading, the Depositary has agreed to reimburse the Company for expenses incurred in connection with the administration and maintenance of the ADS program, including investor relations expenses, annual NYSE listing fees and other program-related expenses, subject to certain limits. The Depositary has also agreed to pay certain standard out-of-pocket maintenance costs for the ADS program. The Company does not currently expect to receive any reimbursement or fees from the Depositary in the near future.

    Evaluation of Disclosure Controls and Procedures

119

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of December 31, 2021). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2021, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. Our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective at a reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting was designed by management to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of its financial statements for external purposes in accordance with IFRS.

In addition, under the Company’s articles of association, as supplemented by the audit committee’s charter, the audit committee assists the board of directors in fulfilling its oversight responsibilities relating to the effectiveness of the Company’s systems of internal control, risk management and internal audit over financial reporting. In particular, the audit committee is required to review the scope and results of the activities of the Company’s external auditors and the internal audit function relating to the Company’s internal control over financial reporting, and obtain reports on significant findings and recommendations; and is also required to assess, at least annually at the time the annual accounts are approved, the effectiveness of the Company’s systems of internal control and risk management over financial reporting.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or omissions. In addition, 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.

On an yearly basis, management conducts its assessment of the effectiveness of Ternium’s internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

On February 15, 2022, management reported to the audit committee that management had conducted its assessment of the effectiveness of the Company’s internal controls over financial reporting for the year ended December 31, 2021, and that, based on management’s evaluation and considering the inherent limitations to the effectiveness of any internal control system, management concluded that the Company’s internal controls over financial reporting were effective as of December 31, 2021.

The effectiveness of Ternium’s internal control over financial reporting as of December 31, 2021 has been audited by PwC Luxembourg, as stated in their report included herein. See “Attestation Report of Registered Public Accounting Firm.”

Attestation Report of Registered Public Accounting Firm

See page F-1 of the audited consolidated financial statements included in this annual report.

Change in Internal Control over Financial Reporting

There were no significant changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the year ended December 31, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

120

The Company’s board of directors has determined that none of the audit committee members meets the attributes defined in Item 16A of Form 20-F for “audit committee financial experts”. However, the audit committee as a whole has sufficient relevant knowledge of the business and financial experience to properly discharge its functions. In addition, the audit committee has the authority to engage, at the Company’s expense, independent counsel and other internal or external advisors to review, investigate or otherwise advise on, any matter, as the audit committee may determine to be necessary to carry out its purposes and responsibilities.

Item 16B. Code of Ethics

Audit Committee’s Pre-approval Policies and Procedures

The Company’s audit committee is responsible for, among other things, the oversight of the Company’s external auditors. The audit committee has adopted in its charter a policy of pre-approval of audit and permissible non-audit services provided by its external auditors.

Under the policy, the audit committee makes its recommendations to the shareholders’ meeting concerning the continuing appointment or termination of the Company’s external auditors. On a yearly basis, the audit committee reviews together with management and the external auditor, the audit plan, audit related services and other non-audit services and approves, ad-referendum of the general shareholders’ meeting, the related fees. Any changes to the approved fees must be reviewed and approved by the audit committee. The general shareholders’ meeting normally approves such audit fees and authorizes the audit committee to approve any increase or reallocation of such audit fees as may be necessary, appropriate or desirable under the circumstances. No services outside the scope of the audit committee’s approval can be undertaken by the external auditor.

During 2021, the audit committee did not approve any fees pursuant to the de minimis exception to the pre-approval requirement provided by paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Item 16D. Exemptions from the Listing Standards for Audit Committees

Not applicable. 

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers

In 2021 and 2022, Inverban Investments S.L., an "affiliate purchaser" (as such term is defined in Rule 10b-18(a)(3) under the Exchange Act), purchased 6,032,422 ADSs of the Company. There were no other purchases of any class of registered equity securities of the Company by the Company or, to our knowledge, by any other affiliated purchaser.

The annual general meeting of shareholders held on May 3, 2021, authorized the Company and the Company’s subsidiaries, for a period of five years, to purchase, acquire or receive, from time to time, shares of the Company, including shares represented by ADSs (collectively, “Securities”), on the terms and conditions set forth below.

•Purchases, acquisitions or receipts of Securities may be made in one or more transactions as the board of directors of the Company or the board of directors or other governing body of the relevant entity, as applicable, considers advisable.

•The maximum number of Securities acquired pursuant to this authorization may not exceed 10% of the Company’s issued and outstanding shares or, in the case of acquisitions made through a stock exchange in which the Securities are traded, such lower amount as may not be exceeded pursuant to any applicable laws or regulations of such market. The number of Securities acquired as a block may amount to the maximum permitted amount of purchases.

•The purchase price per share to be paid in cash may not exceed 125% (excluding transaction costs and expenses), nor may it be lower than 75% (excluding transaction costs and expenses), in each case of the average of the closing prices of the Company’s Securities in the stock exchange through which the Securities are acquired, during the five trading days in which transactions in the Securities were recorded in such stock exchange preceding (but excluding) the day on which the Company's Securities are acquired. For over-the-counter or off-market transactions, the purchase price per ADS to be paid in cash may not exceed 125% (excluding transactions costs and expenses) nor may it be lower than 75% (excluding transaction costs and expenses), in each case of the average of the closing prices of the ADSs in the New York Stock Exchange during the five trading days in which transactions in ADSs were recorded in the New York Stock Exchange preceding (but excluding) the day on which the ADSs are acquired, and, in the case of acquisition of Securities, other than in the form of ADSs, such maximum and minimum per Security purchase prices shall be equal to the prices that would have applied in case of an ADS purchase pursuant to the formula above divided by the number of underlying shares represented by an ADS at the time of the relevant purchase. Compliance with maximum and minimum purchase price requirements in any and all acquisitions made pursuant to this authorization (including, without limitation, acquisitions carried out through the use of derivative financial instruments or option strategies) shall be determined on and as of the date on which the relevant transaction is entered into, irrespective of the date on which the transaction is to be settled.

122

•The above maximum and minimum purchase prices shall, in the event of a change in the par value of the shares, a capital increase by means of a capitalization of reserves, a distribution of shares under compensation or similar programs, a stock split or reverse stock split, a distribution of reserves or any other assets, the redemption of capital, or any other transaction impacting on the Company’s equity, be adapted automatically, so that the impact of any such transaction on the value of the shares shall be reflected.

•The acquisitions of Securities may not have the effect of reducing the Company’s net assets below the sum of the Company’s capital stock plus its undistributable reserves.

•Only fully paid-up Securities may be acquired pursuant to this authorization.

•The acquisitions of Securities may be carried out for any purpose, as may be permitted under applicable laws and regulations, including, without limitation, to reduce the share capital of the Company, to offer such Securities to third parties in the context of corporate mergers or acquisitions of other entities or participating interests therein, for distribution to the Company’s or the Company’s subsidiaries’ directors, officers or employees or to meet obligations arising from convertible debt instruments.

•The acquisitions of Securities may be carried out by any and all means, as may be permitted under applicable laws and regulations, including through any stock exchange in which the Company´s Securities are traded, through public offers to all shareholders of the Company to buy Securities, through the use of derivative financial instruments or option strategies, or in over-the-counter or off-market transactions or in any other manner.

•The acquisitions of Securities may be carried out at any time and from time to time during the duration of the authorization, including during a tender offer period, as may be permitted under applicable laws and regulations.

•The authorization granted to acquire Securities shall be valid for such maximum period as may be provided for under applicable Luxembourg law as in effect from time to time (such maximum period being, as of to date, five years).

•The acquisitions of Securities shall be made at such times and on such other terms and conditions as may be determined by the board of directors of the Company or the board of directors or other governing body of the relevant entity, provided that any such purchase shall comply with Article 430-15 et seq. of the Luxembourg Company Law and, in the case of acquisitions of Securities made through a stock exchange in which such Company's Securities are traded, with any applicable laws and regulations of such market.

In the future, the Company may, on the terms and subject to the conditions above referenced, initiate a share capital repurchase or similar program or engage in other transactions pursuant to which we would repurchase, directly or indirectly, the Company’s Securities. In addition, we or our subsidiaries may enter into transactions involving sales or purchases of derivatives or other instruments (either settled in cash or through physical delivery of securities) with returns linked to the Company’s Securities. The timing and amount of repurchase transactions under any such program, or sales or purchases of derivatives or other instruments, would depend on market conditions as well as other corporate and regulatory considerations. 

Item 16F. Change in Registrant’s Certifying Accountant

Not applicable. 

Item 16G. Corporate Governance

The Company’s corporate governance practices are governed by the Luxembourg Company Law, the Company’s

articles of association and applicable securities laws and regulations. As a Luxembourg company listed on the NYSE, the Company is required to comply with some, but not all, of the corporate governance standards of the NYSE. The Company, however, believes that its corporate governance practices meet, in all material respects, the corporate governance standards that are generally required for controlled companies by the NYSE.

The following is a summary of the significant ways that the Company’s corporate governance practices differ from the corporate governance standards required for foreign controlled companies by the NYSE. The Company’s corporate

123

governance practices may differ in non-material ways from certain other standards required by the NYSE that are not detailed here:

Non-management directors’ meetings

Under NYSE standards, non-management directors must meet at regularly scheduled executive sessions without management present and, if such group includes directors who are not independent, a meeting should be scheduled once per year including only independent directors. Neither Luxembourg law nor the Company’s articles of association require the holding of such meetings and the Company does not have a set policy for these meetings. For additional information on board meetings, please see Item 6. “A. Directors, Senior Management and Employees—Board of Directors”.

In addition, NYSE-listed companies are required to provide a method for interested parties to communicate directly with non-management directors as a group. While the Company does not have such a method, it has set up a compliance line for investors and other interested parties to communicate their concerns directly to the members of our audit committee, all of whom are non-management independent directors.

Audit committee composition

Under NYSE standards, listed U.S. companies are required to have an audit committee composed of independent directors that satisfy the requirements of Rule 10A-3 promulgated under the Exchange Act. Pursuant to the Company’s articles of association, as supplemented by the audit committee’s charter, for as long as the Company's shares are listed on at least one regulated market, the Company must have an audit committee composed of at least three members, the majority of whom must qualify as independent directors (as defined in the Company's articles of association), provided, however, that the composition and membership of the audit committee shall satisfy such requirements as are applicable to, and mandatory for, audit committees of issuers such as the Company under any law, rule or regulation applicable to the Company (including, without limitation, the applicable laws, rules and regulations of such regulated market or markets). The Company’s audit committee, which currently consists of three members, complies with such requirements. In accordance with NYSE standards, the Company has an audit committee entirely composed of independent directors for purposes of the Exchange Act Rule 10A-3(b)(1). For more information on the Company’s audit committee see Item 6. “Directors, Senior Management and Employees—C. Board Practices-Audit Committee”.

Under NYSE standards, all audit committee members of listed U.S. companies are required to be financially literate or must acquire such financial knowledge within a reasonable period and at least one of its members shall have experience in accounting or financial administration. In addition, if a member of the audit committee is simultaneously a member of the audit committee of more than three public companies, and the listed company does not limit the number of audit committees on which its members may serve, then in each case the board must determine whether the simultaneous service would prevent such member from effectively serving on the listed company’s audit committee and shall publicly disclose its decision. No comparable provisions on audit committee membership exist under applicable Luxembourg law or the Company’s articles of association.

Standards for evaluating director independence

Under NYSE standards, the board is required, on a case-by-case basis, to express an opinion with regard to the independence or lack of independence of each individual director. Neither Luxembourg law nor the Company’s

articles of association requires that the board of directors express such an opinion. In addition, the definition of “independent” under the NYSE rules differs in some non-material respects from the definition contained in the Company’s articles of association. For more information on the Company's independent directors and the definition of “independent” under the Company's articles of association, see Item 6. “Directors, Senior Management and Employees—C. Board Practices-Audit Committee”.

Audit committee responsibilities

Pursuant to the Company’s articles of association, the audit committee shall assist the board of directors in fulfilling its oversight responsibilities relating to the integrity of its consolidated financial statements, the effectiveness of its systems of internal control, risk management and internal audit over financial reporting and the independence and performance of the external auditors. The audit committee is required to review and, where applicable, approve material transactions between the Company or its subsidiaries and related parties and also perform the other duties

124

entrusted to it by the board. The NYSE requires certain matters to be set forth in the audit committee charter of U.S. listed companies.

The Company’s audit committee charter provides for many of the responsibilities that are expected from such bodies under the NYSE standard; however, due to the Company’s equity structure and holding company nature, the charter does not contain all such responsibilities, including provisions related to procedures for the receipt and treatment of complaints (although the Company has established such procedures), funding for payment of administrative expenses and compensation to advisors (although the audit committee has the authority to engage outside advisors), setting hiring policies for employees or former employees of external auditors and an annual performance evaluation of the audit committee. For more information on the Company’s audit committee see Item 6. “Directors, Senior Management and Employees—C. Board Practices-Audit Committee”.

Standards for approval of related-party transactions

The Company is subject to Luxembourg laws governing approval of material related party transactions; and the Company’s articles of association and the audit committee charter require the audit committee to review material transactions with related parties to determine whether their terms are consistent with the interests of the Company and its shareholders and with market conditions. In addition, recently amended NYSE standard on related-party transactions requires all NYSE-listed companies’ audit committees (or another independent body of the board of directors) to conduct a reasonable prior review and oversight of all related party transactions for potential conflicts of interest and to prohibit such a transaction if it determines it to be inconsistent with the interests of the Company and its shareholders. The rule defines the term “related party transaction” by reference to the disclosure requirements for annual reports under the Exchange Act. The materiality threshold applicable to foreign private issuers differs to the one applicable to U.S companies. For further details on the approval process for related party transactions, see Item 6.C. “Directors, Senior Management and Employees – Board Practices – Audit Committee”.

Shareholder voting on equity compensation plans

Under NYSE standards, shareholders must be given the opportunity to vote on equity-compensation plans and material revisions thereto, except for employment inducement awards, certain grants, plans and amendments in the context of mergers and acquisitions, and certain specific types of plans. The Company does not currently offer equity-based compensation to its directors, senior management or employees, and therefore does not have a policy on this matter. For further information on directors' compensation, see Item 6. “Directors, Senior Management and Employees—B. Compensation”.

Disclosure of corporate governance guidelines

NYSE-listed companies must adopt and disclose corporate governance guidelines. Neither Luxembourg law nor the Company’s articles of association require the adoption or disclosure of corporate governance guidelines. The Company’s board of directors follows corporate governance guidelines consistent with its equity structure and holding company nature, but the Company has not codified them and therefore does not disclose them on its website.

Code of business conduct and ethics

Under NYSE standards, listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers. Neither Luxembourg law nor the Company’s articles of association require the adoption or disclosure of such a code of conduct. The Company, however, has adopted a code of conduct that applies to all directors, officers and employees, that is posted on its website and which complies with the NYSE’s requirements, except that it does not require the disclosure of waivers of the code for directors and officers. In addition, it has adopted a supplementary code of ethics for senior financial officers which is also posted on our website. For further information, see Item 16B. “Code of Ethics”.

Chief Executive Officer certification

A chief executive officer of a U.S. company listed on the NYSE must annually certify that he or she is not aware of any violation by the company of NYSE corporate governance standards. In accordance with NYSE rules applicable to foreign private issuers, the Company’s chief executive officer is not required to provide the NYSE with this annual compliance certification. However, in accordance with NYSE rules applicable to all listed companies, the Company’s

125

chief executive officer must promptly notify the NYSE in writing after any of the Company’s executive officers becomes aware of any noncompliance with any applicable provision of the NYSE’s corporate governance standards. In addition, the Company must submit an executed written affirmation annually and an interim written affirmation upon the occurrence of any of the events listed in the foreign private issuer interim written affirmation form by the NYSE.

Opinions on the Consolidated Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Ternium S.A. and its subsidiaries (the “Company”) as of 31 December 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 31 December 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 31 December 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organisations 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 31 December 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended 31 December 2021 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and International Financial Reporting Standards as adopted by the European Union. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 31 December 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

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

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-2

Uncertain tax position in Mexico

As described in Note 24 (c) to the consolidated financial statements, the Company is subject to potential income tax adjustments in Mexico arising from tax audits performed by Mexican tax authorities in 2015 and 2018. Management's estimate of these adjustments is USD 84 million, including interest and fines. Based on the advice of counsel, management believes that an unfavorable outcome is not probable and no provision has therefore been established in the consolidated financial statements. Management applied significant judgment in estimating this uncertain tax position.

The principal considerations for our determination that performing procedures relating to the uncertain tax position in Mexico is a critical audit matter are (i) the significant judgment by management when determining this uncertain tax position, including a high degree of estimation uncertainty relative to the complex tax laws and potential for significant adjustments as a result of such matter; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s accurate measurement and disclosure of this uncertain tax position; (iii) the evaluation of audit evidence available to support the uncertain tax position in Mexico is complex and resulted in significant auditor judgment as the nature of the evidence is often highly subjective; and (iv) 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 measurement and disclosure of the balances relating to the uncertain tax position in Mexico. These procedures also included, among others, (i) testing the information used in the determination of the amount of the contingencies for the uncertain tax position in Mexico, including, where appropriate, the related tax returns; (ii) testing the calculation of the contingencies relating to the uncertain tax position in Mexico, including management’s assessment of the technical merits of tax position and estimates of the amount of tax benefit expected to be sustained or potentially claimed; (iii) evaluating the status and results of income tax audits and ongoing legal actions; (iv) obtaining and evaluating opinions from management’s legal advisors in respect to this tax matter. Professionals with specialized skill and knowledge were used to assist in the evaluation of management’s estimates in respect of the uncertain tax position in Mexico, including evaluating the reasonableness of management’s assessment of whether tax position is more-likely-than-not of being sustained and the amount of potential liability to be realized, the application of relevant tax laws, and estimated interest and penalties.

Notes to the Consolidated Financial Statements

1.    GENERAL INFORMATION

Ternium S.A. (the “Company” or “Ternium”), was incorporated on December 22, 2003 to hold investments in flat and long steel manufacturing and distributing companies. The Company has an authorized share capital of a single class of 3.5 billion shares having a nominal value of $1.00 per share. As of December 31, 2021, there were 2,004,743,442 shares issued. All issued shares are fully paid.

Ternium’s American Depositary Shares ("ADSs") trade on the New York Stock Exchange under the symbol “TX”.

The Company was initially established as a public limited liability company (société anonyme) under Luxembourg’s 1929 holding company regime. Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929 regime (including the Company) were exempt from Luxembourg corporate and withholding tax over dividends distributed to shareholders.

On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, effective as from that date, the Company is subject to all applicable Luxembourg taxes (including, among others, corporate income tax on its worldwide income) and its dividend distributions will generally be subject to Luxembourg withholding tax. However, dividends received by the Company from subsidiaries in high income tax jurisdictions, as defined under Luxembourg law, will continue to be exempt from corporate income tax in Luxembourg under Luxembourg’s participation exemption.

As part of the Company’s corporate reorganization in connection with the termination of Luxembourg’s 1929 holding company regime, on December 6, 2010, the Company contributed its equity holdings in all its subsidiaries and all its financial assets to its Luxembourg wholly-owned subsidiary Ternium Investments S.à.r.l., or Ternium Investments, in exchange for newly issued corporate units of Ternium Investments. As the assets contributed were recorded at their historical carrying amount in accordance with Luxembourg GAAP, the Company’s December 2010 contribution of such assets to Ternium Investments resulted in a non-taxable revaluation of the accounting value of the Company’s assets under Luxembourg GAAP. The amount of the December 2010 revaluation was equal to the difference between the historical carrying amounts of the assets contributed and the value at which such assets were contributed and amounted to $4.0 billion. However, for the purpose of these consolidated financial statements, the assets contributed by Ternium to its wholly-owned subsidiary Ternium Investments were recorded based on their historical carrying amounts in accordance with IFRS, with no impact on the financial statements.

Following the completion of the corporate reorganization, and upon its conversion into an ordinary Luxembourg holding company, the Company voluntarily recorded a special reserve exclusively for tax-basis purposes. As of December 31, 2021 and 2020, this special tax reserve amounted $5.8 billion and $6.3 billion, respectively. The Company expects that, as a result of its corporate reorganization, its current overall tax burden will not increase, as all or substantially all of its dividend income will come from high income tax jurisdictions.

3.    ACCOUNTING POLICIES

The following is a summary of the principal accounting policies followed in the preparation of these Consolidated Financial Statements:

(a)Group accounting

(1)    Subsidiary companies and transactions with non-controlling interests

Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at the fair values at the acquisition date. Indemnification assets are recognized at the same time that the Company recognizes the indemnified item and measures them on the same basis as the indemnified item, subject to the need for a valuation allowance for uncollectible amounts. The Company measures the value of a reacquired right recognized as an intangible asset on the basis of the remaining contractual term of the related contract regardless of whether market participants would consider potential contractual renewals in determining its fair value.

On an acquisition-by-acquisition basis, the Company recognizes any non-controlling interest in the acquiree at the non-controlling interest's proportionate share of the acquiree's net assets.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the Company's share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

The measurement period is the earlier of the date that the acquirer receives the information that it is looking for or cannot obtain the information and one year after the acquisition date. Where the accounting for a business combination is not complete by the end of the reporting period in which the business combination occurred provisional amounts are reported.

The Company treats transactions with non-controlling interests as transactions with equity owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

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

3.    ACCOUNTING POLICIES (continued)

When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the group. However, the fact that the functional currency of some subsidiaries is their respective local currency, generates some financial gains (losses) arising from intercompany transactions, that are included in the consolidated income statement under Other financial expenses, net.

(2)    Investments in non-consolidated companies

Associated companies are those entities in which Ternium has significant influence, but which it does not control.

Joint arrangements are understood as combinations in which there are contractual agreements by virtue of which two or more companies hold an interest in companies that undertake operations or hold assets in such a way that any financial or operating decision is subject to the unanimous consent of the partners. A joint arrangement is classed as a joint operation if the parties hold rights to its assets and have obligations in respect of its liabilities or as a joint venture if the venturers hold rights only to the investee's net assets.

Investments in non-consolidated companies (associated companies and joint ventures) are accounted for using the equity method of accounting. Under this method, interests in joint ventures and associates are initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Company’s share of the post-acquisition profits or losses in the income statement, and its share of post-acquisition changes in reserves recognized in reserves and in other comprehensive income in the income statement. Unrealized gains on transactions among the Company and its non-consolidated companies are eliminated to the extent of the Company’s interest in such non-consolidated companies; unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. When the Company’s share of losses in a non-consolidated company equals or exceeds its interest in such non-consolidated company, the Company does not recognize further losses unless it has incurred obligations or made payments on behalf of such non-consolidated company.

The Company’s investment in associates and joint ventures includes notional goodwill identified on acquisition.

The Company determines at each reporting date whether there is any objective evidence that the investment is impaired. If this is the case, the group calculates the amount of impairment as the difference between the recoverable amount of the investment and its carrying value and recognizes the amount within “Equity on earnings (losses) of non-consolidated companies”.

3.    ACCOUNTING POLICIES (continued)

(b)Foreign currency translation

(1)Functional and presentation currency

Items included in the financial statements of each of the Company's subsidiaries and associated companies are measured using the currency of the primary economic environment in which the entity operates (the "functional currency"). Except for the non-consolidated companies whose functional currencies are their local currencies, Ternium determined that the functional currency of its subsidiaries is the U.S. dollar. Although Ternium is located in Luxembourg, it operates in several countries with different currencies. The $ is the currency that best reflects the economic substance of the underlying events and circumstances relevant to Ternium as a whole.

(2)    Subsidiary companies

The results and financial position of all the group entities (except for the ones which operated in a hyperinflationary economy) that have a functional currency different from the presentation currency, are translated into the presentation currency as follows:

(i) assets and liabilities are translated at the closing rate of each statement of financial position;

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

(iii) all resulting translation differences are recognized within other comprehensive income.

In the case of a sale or other disposition of any such subsidiary, any accumulated translation differences would be recognized in the income statement as part of the gain or loss on sale.

(3)    Transactions in currencies other than the functional currency

Transactions in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation where items are re-measured.

At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency are translated using the closing rates, (ii) non-monetary items that are measured in terms of historical cost in a currency other than the functional currency are translated using the exchange rates prevailing at the date of the transactions; and (iii) non-monetary items that are measured at fair value in a currency other than the functional currency are translated using the exchange rates prevailing at the date when the fair value was determined.

Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than the functional currency are recorded as gains and losses from foreign exchange and included in "Other financial income (expenses), net" in the consolidated income statement, except when deferred in equity as qualifying cash flow hedges and qualifying net investment hedges. Translation differences on non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the "fair value gain or loss," while translation differences on non-monetary financial assets such as equities classified as fair value through other comprehensive income are included in other gains/(losses).

3.    ACCOUNTING POLICIES (continued)

(c)Financial instruments

Non derivative financial instruments

Non derivative financial instruments comprise investments in equity and debt securities, trade and other receivables, cash and cash equivalents, loans and borrowings, and trade and other payables.

The Company classifies its financial instruments in the following measurement categories:

–Amortized cost: instruments that are held for collection or repayment of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. Interest income and expenses from these financial instruments are included in finance income or expense using the effective interest rate method. Any gain or loss arising on derecognition is recognized directly in profit or loss and presented in finance income or expense, together with foreign exchange gains and losses. Impairment losses are presented as separate line items in the statement of profit or loss.

–Fair value through other comprehensive income (“FVOCI”): financial assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity to profit or loss and recognized in other gains/(losses). Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses) and impairment expenses are presented as separate line item in the statement of profit or loss.

–Fair value through profit or loss (“FVPL”): financial instruments that do not meet the criteria for amortized cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognized in profit or loss and presented net within other gains/(losses) in the period in which it arises.

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

For financial instruments measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the group has made an irrevocable election at the time of initial recognition to account for the equity investment at FVOCI.

At initial recognition, the Company measures a financial instrument at its fair value plus, in the case of a financial instrument not at FVPL, transaction costs that are directly attributable to the acquisition of the financial instrument. Transaction costs of financial instruments carried at FVPL are expensed in profit or loss. Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset.

3.    ACCOUNTING POLICIES (continued)

The classification depended on the nature and purpose of the financial assets and was determined at the time of initial recognition.

Financial assets and liabilities were recognized and derecognized on the settlement date.

Financial assets were initially measured at fair value, net of transaction costs, except for those financial assets classified as financial assets at fair value through profit or loss.

Financial liabilities, including borrowings, were initially measured at fair value, net of transaction costs and subsequently measured at amortized cost using the effective interest method, with interest expense recognized on an effective yield basis.

Impairment of financial assets

The Company assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk.

For trade receivables, the Company applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognized from initial recognition of the receivables, see note 3 (i) for further details.

For loans and receivables category and for held-to-maturity investments, the amount of the loss was measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset's original effective interest rate. The carrying amount of the asset was reduced and the amount of the loss was recognized in the consolidated income statement.

If, in a subsequent period, the amount of the impairment loss decreased and the decrease could be related objectively to an event occurring after the impairment was recognized, the reversal of the previously recognized impairment loss was recognized in the consolidated income statement.

Derivative financial instruments

Information about accounting for derivative financial instruments and hedging activities is included in Note 28 "Financial Risk management" and Note 3 (y).

3.    ACCOUNTING POLICIES (continued)

(d)Property, plant and equipment

(1) Property, plant and equipment

Land and buildings comprise mainly factories and offices. All property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation and accumulated impairment (if applicable), except for land, which is carried at acquisition cost less accumulated impairment (if applicable). There are no material residual values for property, plant and equipment items.

Major overhaul and rebuilding expenditures are recognized as a separate asset when future economic benefits are expected from the item, and the cost can be measured reliably.

Ordinary maintenance expenses on manufacturing properties are recorded as cost of products sold in the period in which they are incurred.

Where a tangible fixed asset comprises major components having different useful lives, these components are accounted for as separate items. Spare parts are included in property, plant and equipment.

Depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to amortize the cost of each asset to its residual value over its estimated useful life as follows:

Land	No depreciation
Buildings and improvements	10-50 years
Production equipment	5-40 years
Vehicles, furniture and fixtures and other equipment	3-20 years

Property, plant and equipment used in mining activities are depreciated over its useful life or over the remaining life of the mine if shorter and there is no alternative use possible.

The assets' useful lives are reviewed, and adjusted if appropriate, at each year end. The re-estimation of assets useful lives by the Company did not materially affect depreciation charges in 2021, 2020 and 2019.

Gains and losses on disposals are determined by comparing the proceeds with the corresponding carrying amounts and are included in the income statement.

If the carrying amount of an asset were greater than its estimated recoverable amount, it would be written down to its recoverable amount (see Note 3 (f) "Impairment").

Amortization charges are included in cost of sales, selling, general and administrative expenses.

3.    ACCOUNTING POLICIES (continued)

(2) Right-of-use assets

The Company is a party to lease contracts for:

–Land

–Plants and equipment for the production of industrial gases and other production materials.

–Transportation and maintenance equipment.

–Warehouses and office spaces.

These leases are recognized, measured and presented in accordance to IFRS 16 “Leases”, following the guidelines described below.

Accounting by the lessee

The Company recognizes a right-of-use asset and a lease liability at the commencement date of each lease contract that grants the right to control the use of an identified asset during a period of time. The commencement date is the date in which the lessor makes an underlying asset available for use by the lessee.

The Company applied exemptions for leases with a duration lower than 12 months, with a value lower than thirty thousand dollars and/or with clauses related to variable payments. These leases have been considered as short-term leases and, accordingly, no right-of-use asset or lease liability have been recognized.

At initial recognition, the right-of-use asset is measured considering:

– The value of the initial measurement of the lease liability;

– Any lease payments made at or before the commencement date, less any lease incentives; and

– Any initial direct costs incurred by the lessee.

After initial recognition, the right-of-use assets are measured at cost, less any accumulated depreciation and/or impairment losses, and adjusted for any re-measurement of the lease liability.

Depreciation of the right-of-use asset is calculated using the straight-line method over the estimated duration of the lease contract, as follows:

Buildings and facilities        1-28 years

Machinery            1-11 years

If the lease transfers ownership of the underlying asset to the Company by the end of the lease term, or if the cost of the right-of-use asset reflects that the Company will exercise a purchase option, the Company depreciates the right-of-use asset from the commencement date to the end of the useful life of the underlying asset. Otherwise, the Company depreciates the right-of-use asset from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.

Accounting by the lessor

When the Company is acting as a lessor, each of its leases is classified as either operating or finance lease:

– Leases where a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases.

– Leases where all substantial risks and rewards of ownership are transferred by the lessor to the lessee are classified as finance leases.

3.    ACCOUNTING POLICIES (continued)

(e)Intangible assets

(1)    Information system projects

Generally, costs associated with developing or maintaining computer software programs are recognized as an expense as incurred. However, costs directly related to the acquisition and implementation of information systems are recognized as intangible assets if they have a probable economic benefit exceeding the cost beyond one year and comply with the recognition criteria of IAS 38.

Information system projects recognized as assets are amortized using the straight-line method over their useful lives, not exceeding a period of 3 years. Amortization charges are included in cost of sales, selling, general and administrative expenses.

(2)    Mining assets

Mining assets include:

(a)Mining licenses acquired;

(b)Capitalized exploration and evaluation costs, reclassified from exploration and evaluation costs (see note 3 (e) 3); and

(c)Capitalized developmental stripping costs (see note 3 (u)).

Mining licenses were recognized as separate intangible assets upon the acquisition of the investment in Mexico and comprise the right to exploit the mines and are recognized at its fair value at acquisition date less accumulated amortization.

These mining concessions were granted for a 50-year period; following the expiration of the initial concession term, the concessions are renewable for an additional 50-year term in accordance with, and subject to the procedures set forth in, applicable Mexican mining law.

Amortization charge is calculated by using the unit-of-production method, on the basis of actual mineral extracted in each period compared to the estimated mineral reserves, and is included in cost of sales. Any change in the estimation of reserves is accounted for prospectively. The resulting amortization rate for the years ended December 31, 2021, 2020 and 2019, is approximately 7%, 4% and 5% per year, respectively.

(3)Exploration and evaluation costs

Exploration and evaluation activities involve the search for iron ore resources, the determination of technical feasibility and the assessment of commercial viability of an identified resource.

Exploration and evaluation costs are measured at cost. Costs directly associated with exploration and evaluation activities are capitalized as intangible assets until the determination of reserves is evaluated. The costs associated to the acquisition of machinery and equipment are recognized as property, plant and equipment. If it is determined that commercial discovery has been achieved, costs incurred are reclassified into Mining assets and amortization starts once production begins.

Exploration costs are tested for impairment annually or whenever there are indicators that impairment exists. Indicators of impairment include, but are not limited to:

–Rights to explore in an area have expired or will expire in the near future without renewal;

–No further exploration and evaluation is planned or budgeted;

–A decision to discontinue exploration and evaluation in an area because of the absence of commercial reserves; and

–Sufficient data exists to indicate that the book value will not be fully recovered from future development and production.

When analyzing the existence of impairment indicators, the exploration and evaluation areas from the mining units will be evaluated.

(4)    Goodwill

Goodwill represents the excess of the acquisition cost over the fair value of Ternium's participation in acquired companies' net assets at the acquisition date. Under IFRS 3, goodwill is considered to have an indefinite life and not amortized, but is subject to annual impairment testing.

Goodwill is allocated to Cash-generating units ("CGU") for the purpose of impairment testing. The allocation is made to those cash-generating units expected to benefit from the business combination which generated the goodwill being tested. The impairment losses on goodwill cannot be reversed.

As of December 31, 2021 and 2020, the carrying amount of goodwill allocated to the Mexico CGU was $662.3 million, of which $619.8 million corresponds to steel operations and $42.5 million to mining operations.

(5)    Research and development

Research expenditures are recognized as expenses as incurred. Development costs are recorded as cost of sales in the income statement as incurred because they do not fulfill the criteria for capitalization. Research and development expenditures for the years ended December 31, 2021, 2020 and 2019 totaled $9.8 million, $8.3 million and $10.0 million, respectively.

(6)    Customer relationships acquired in a business combination

In accordance with IFRS 3 and IAS 38, Ternium has recognized the value of customer relationships in connection with the acquisition of Ternium Staal B.V. as of September 7, 2017. The value of the slab commitment agreement by which Ternium Investments S.à r.l. was entitled to invoice, under certain conditions, the price difference between slabs and hot rolled coils has been amortized using the units of slabs sold method. As of December 31, 2021, the asset related to this slab commitment agreement was fully amortized.

(7)    Trademarks acquired in a business combination

Trademarks are amortized using the straight-line method over a useful life of between 5 to 10 years.

(f)    Impairment

Assets that have an indefinite useful life (including goodwill) are not subject to amortization and are tested annually for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets that are subject to amortization and investments in affiliates are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less cost to sell and the value in use.

To carry out these tests, assets are grouped at the lowest levels for which there are separately identifiable cash flows (each, a CGU). When evaluating long-lived assets for potential impairment, the Company estimates the recoverable amount based on the value in use of the corresponding CGU. The value in use of each CGU is determined on the basis of the present value of net future cash flows which will be generated by the assets tested.

Determining the present value of future cash flows involves highly sensitive estimates and assumptions specific to the nature of each CGU's activities, including estimates and assumptions relating to amount and timing of projected future cash flows, expected changes in market prices, expected changes in the demand of Ternium products and services, selected discount rate and selected tax rate.

Ternium uses, for the steel segment impairment tests, cash flow projections for the next five years based on past performance and expectations of market development; thereafter, it uses a perpetuity rate. In the case of CGU Mexico, cash flow projections are prepared until the mines are fully depleted and are based on past performance and expectations of market development; then a perpetuity rate starts. The growth rate used for the perpetuity rate is of 2.3%. Application of the discounted cash flow (DCF) method to determine the value in use of a CGU begins with a forecast of all expected future net cash flows. Variables considered in forecasts include the gross domestic product (GDP) growth rates of the country under study and their correlation with steel demand, level of steel prices and estimated raw material costs as observed in industry reports.

3.    ACCOUNTING POLICIES (continued)

Cash flows are discounted at rates that reflect specific country and currency risks associated with the cash flow projections. The discount rates used are based on the weighted average cost of capital (WACC), which is considered to be a good indicator of cost of capital. As of December 31, 2021 the discount rate used to test goodwill allocated to the Steel and Mining Mexico CGU for impairment was 9.93% (as of December 31, 2020, 8.87%).

As a result of the above factors, actual cash flows and values could vary significantly from the forecasted future cash flows and related values derived using discounting techniques. Based on the information currently available, however, Ternium believes that it is not reasonably possible that the variation would cause the carrying amount to exceed the recoverable amount of the CGUs.

Considering the economic situation in Argentina, the increase in the inflation rates, the devaluation of the Argentine peso and a weaker industrial environment as of June 30, 2020, the Company decided to assess the recoverability of its investments in Argentina, resulting in no impairment charges to be recognized. As of June 30, 2020, the discount rate used to test the investment in Argentine subsidiaries for impairment was 14.3%. Also, considering the economic situation in Brazil as of June 30, 2020, the Company decided to assess the recoverability of its investments in Brazil, resulting in no impairment charges to be recognized. As of June 30, 2020, the discount rate used to test the investment in the Brazilian subsidiary for impairment was 10.3%. As of December 31, 2021 and 2020, no new impairment triggers were detected in these CGUs and, consequently, no impairment tests were prepared.

In connection with investments in non-consolidated companies and considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company decided to assess the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. As of December 31, 2021, the discount rate used to test the investment in Usiminas for impairment was 11.95%.

During the years 2021, 2020 and 2019, no impairment provisions were recorded in connection with assets that have an indefinite useful life (including goodwill).

(g)     Other investments

Other investments consist primarily of investments in financial debt instruments and equity investments where the Company holds a minor equity interest and does not exert significant influence.

All purchases and sales of investments are recognized on the settlement date, which is not significantly different from the trade date, which is the date that Ternium commits to purchase or sell the investment.

Income from financial instruments at fair value through profit or loss is recognized in Other financial income (expenses), net in the consolidated income statement. The fair value of quoted investments is based on current bid prices. If the market for a financial investment is not active or the securities are not listed, the Company estimates the fair value by using standard valuation techniques. Dividends from investments in equity instruments are recognized in the income statement when the Company's right to receive payments is established.

Certain fixed income financial instruments purchased by the Company have been categorized as at fair value through other comprehensive income. The results of these financial investments are recognized in Finance Income in the Consolidated Income Statement using the effective interest method. Unrealized gains and losses other than impairment and foreign exchange results are recognized in Other comprehensive income. On maturity or disposal, net gain and losses previously deferred in Other comprehensive income are recognized in Finance Income in the Consolidated Income Statement.

3.    ACCOUNTING POLICIES (continued)

(h)Inventories

Inventories are stated at the lower of cost (calculated using the first-in-first-out "FIFO" method) or net realizable value. The cost of finished goods and goods in process comprises raw materials, direct labor, depreciation, other direct costs and related production overhead costs. It excludes borrowing costs. Goods acquired in transit at year end are valued at supplier's invoice cost.

The cost of iron ore produced in our mines comprises all direct costs necessary to extract and convert stockpiled inventories into raw materials, including production stripping costs, depreciation of fixed assets related to the mining activity and amortization of mining assets for those mines under production.

The Company assesses the recoverability of its inventories considering their selling prices, if the inventories are damaged, or if they have become wholly or partially obsolete (see note 3 (bb) (4)).

(i)Trade receivables and other receivables

Trade and other receivables are recognized initially at fair value, generally the original invoice amount. The Company applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables are grouped based on shared credit risk characteristics and the days past due. The Company keeps an allowance for trade receivables, recorded in an asset account to offset the trade receivables in an amount estimated sufficient to cover the losses resulting from the impossibility for the debtors to cancel the amounts owed. This allowance for trade receivables is recorded with a charge to selling expenses.

(j)    Cash and cash equivalents

Cash and cash equivalents and highly liquid short-term securities are carried at fair market value or at a historical cost which approximates fair market value.

For purposes of the cash flow statement, cash and cash equivalents comprise cash, bank current accounts and short-term highly liquid investments (original maturity of three months or less at date of acquisition) and overdrafts.

In the consolidated statement of financial position, bank overdrafts are included in borrowings within current liabilities.

(k)     Assets (disposal groups) classified as held for sale

Assets (disposal groups) are classified as assets held for sale, complying with the recognition criteria of IFRS 5, and stated at the lower of carrying amount and fair value less cost to sell if their carrying amount is recovered principally through a sale transaction rather than through continuing use.

The carrying value of assets classified as held for sale, at December 31, 2021 and 2020 totals $1.9 million and $5.0 million, respectively, which corresponds principally to land and other real estate items. Sale is expected to be completed within a one-year period.

3.    ACCOUNTING POLICIES (continued)

(l)     Borrowings

Borrowings are recognized initially for an amount equal to the net proceeds received. In subsequent periods, borrowings are stated at amortized cost following the effective interest method.

(m)    Lease liabilities

The lease liability is initially measured at the present value of the lease payments that are not paid at such date, including the following concepts:

– Fixed payments, less any lease incentives receivable;

– Variable lease payments that depend on an index or rate, initially measured using the index or rate as of the commencement date;

– Amounts expected to be payable by the lessee under residual value guarantees;

– The exercise price of a purchase option if the lessee is reasonably certain to exercise that option; and

– Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

Variable lease liabilities with payments dependent on external factors, such as minimum volumes sold or used, are not included in the initial measurement of the lease liabilities and such payments are recognized directly in profit and loss.

Lease payments are discounted using incremental borrowing rates for the location and currency of each lease contract or, if available, the rate implicit in the lease contract.

The finance cost is charged to profit or loss over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

The lease term determined by the Company comprises:

– Non-cancelable period of lease contracts;

– Periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and

– Periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option.

After the commencement date, the Company measures the lease liability by:

– Increasing the carrying amount to reflect interest on the lease liability;

– Reducing the carrying amount to reflect lease payments made; and

– Re-measuring the carrying amount to reflect any reassessment or lease modifications.

(n)    Income taxes - current and deferred

The current income tax charge is calculated on the basis of the tax laws in force in the countries in which Ternium and its subsidiaries operate. Management evaluates positions taken in tax returns with respect to situations in which applicable tax regulation could be subject to interpretation. A liability is recorded for tax benefits that were taken in the applicable tax return but have not been recognized for financial reporting.

3.    ACCOUNTING POLICIES (continued)

Deferred income taxes are calculated using the liability method on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting, nor taxable profit or loss. The principal temporary differences arise on fixed assets, intangible assets, inventories valuation and provisions for pensions. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantially enacted at year end. Under IFRS, deferred income tax assets (liabilities) are classified as non-current assets (liabilities).

Deferred tax assets are recognized to the extent it is probable that future taxable income will be available to offset temporary differences.

Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associated companies, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.

Deferred tax assets and liabilities are re-estimated if tax rates change. These amounts are charged or credited to the consolidated income statement or to the item “Other comprehensive income for the year” in the consolidated statement of comprehensive income, depending on the account to which the original amount was charged or credited.

(o)    Employee liabilities

(1)    Post-employment obligations

The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually (at year end) by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. In countries where there is no deep market in such bonds, the market rates on government bonds are used.

Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise. Past-service costs are recognized immediately in income.

For defined benefit plans, net defined benefit liability/asset is calculated based on the surplus or deficit derived by the difference between the defined benefit obligations less plan assets.

3.    ACCOUNTING POLICIES (continued)

For defined contribution plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

Mexico

Ternium Mexico has defined benefit and defined contribution plans.

The valuation of the liabilities for the defined benefit employee retirement plans (pensions and seniority premiums) covers all employees and is based primarily on their years of service, their present age and their remuneration at the date of retirement. The cost of the employee retirement plans (pension, health-care expenses and seniority premiums) is recognized as an expense in the year in which services are rendered in accordance with actuarial studies made by independent actuaries. The formal retirement plans are congruent with and complementary to the retirement benefits established by the Mexican Institute of Social Security. Additionally, the Company has established a plan to cover health-care expenses of retired employees. The Company has established a commitment for the payment of pensions and seniority premiums, as well as for health-care expenses.

The defined contribution plans provide a benefit equivalent to the capital accumulated with the company's contributions, which are provided as a match of employees' contributions to the plan. The plan provides vested rights according to the years of service and the cause of retirement.

Argentina

Ternium Argentina implemented an unfunded defined benefit employee retirement plan for certain senior officers. The plan is designed to provide certain benefits to those officers (additional to those contemplated under applicable Argentine labor laws) in case of termination of the employment relationship due to certain specified events, including retirement. This unfunded plan provides defined benefits based on years of service and final average salary.

(2)Termination benefits

Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits when it is demonstrably committed to either: (i) terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal or (ii) providing termination benefits as a result of an offer made to encourage voluntary redundancy.

(3)    Other compensation obligations

Employee entitlements to annual leave and long-service leave are accrued as earned.

3.    ACCOUNTING POLICIES (continued)

During 2007, Ternium launched an incentive retention program (the "Program") applicable to certain senior officers and employees of the Company, who will be granted a number of Units throughout the duration of the Program. The value of each of these Units is based on Ternium's shareholders' equity (excluding non-controlling interest). Also, the beneficiaries of the Program are entitled to receive cash amounts based on (i) the amount of dividend payments made by Ternium to its shareholders, and (ii) the number of Units held by each beneficiary to the Program. Units vest ratably over a period of four years and will be redeemed by the Company ten years after grant date, with the option of an early redemption at seven years after grant date. From 2018 units were vest ratably over the same period and will be mandatorily redeemed by the Company seven years after grant date. As the cash payment of the benefit is tied to the book value of the shares, and not to their market value, Ternium valued this long-term incentive program as a long term benefit plan as classified in IAS 19.

As of December 31, 2021 and 2020, the outstanding liability corresponding to the Program amounts to $67.7 million and $43.4 million, respectively. The total value of the units granted to date under the program, considering the number of units and the book value per share as of December 31, 2021 and 2020, is $72.1 million and $43.3 million, respectively.

Under Mexican law, Ternium's subsidiaries are required to pay their employees an annual benefit which is determined as a percentage of taxable profit for the year.

(4)    Social security contributions

Social security laws in force in the countries in which the Company operates provide for pension benefits to be paid to retired employees from government pension plans and/or private fund managed plans to which employees may elect to contribute. As stipulated by the respective laws, Ternium Argentina and Ternium Mexico make monthly contributions calculated based on each employee's salary to fund such plans. The related amounts are expensed as incurred. No additional liabilities exist once the contributions are paid.

(p)    Provisions

Ternium has certain contingencies with respect to existing or potential claims, lawsuits and other proceedings. Unless otherwise specified, Ternium accrues a provision for a present legal or constructive obligation as a result of a past event, when it is probable that future cost could be incurred and that cost can be reasonably estimated. Generally, accruals are based on developments to date, Ternium's estimates of the outcomes of these matters and the advice of Ternium's legal advisors.

(q)    Trade payables

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.

3.    ACCOUNTING POLICIES (continued)

(r)    Revenue recognition and other income

Revenue is recognized at a point of time from sales to direct customers upon the satisfaction of performance obligations, which occurs when control of the goods transfers to the customer and the customer obtains the benefits from the goods, the potential cash flows and the transaction price can be measured reliably, and it is probable that the Company will collect the consideration in connection with the exchange of the goods. The control over the goods is obtained by the customer depending on when the goods are made available to the shipper or the customer takes possession of the goods, depending on the delivery terms. The Company considers that it has completed its performance obligations when the goods are delivered to its customers or to a shipper who will transport the goods to its customers. The revenue recognized by the Company is measured at the transaction price of the consideration received or receivable to which the Company is entitled to, reduced by estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized and after eliminating sales within the group.

Interest income is recognized on an effective yield basis.

(s)    Borrowing Costs

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

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

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

The amount of borrowing costs that Ternium capitalized during a period will not exceed the amount of borrowing costs incurred during that period. At December 31, 2021, 2020 and 2019, the capitalized borrowing costs were of $6.3 million, $13.1 million and $16.1 million, respectively.

(t)    Cost of sales, selling, general and administrative expenses

Cost of sales and expenses are recognized in the income statement on the accrual basis of accounting.

Commissions, freight and other selling expenses, including shipping and handling costs, are recorded in Selling, general and administrative expenses in the Consolidated Income Statement.

(u)    Stripping costs

Stripping costs are the costs associated with the removal of overburden and other waste materials and can be incurred before the mining production commences (“development stripping”) or during the production stage (“production stripping”).

3.    ACCOUNTING POLICIES (continued)

Development stripping costs that contribute to the future economic benefits of mining operations are capitalized as intangible assets (Mining assets). Production stripping costs which are part of on-going activities are included in the cost of the inventory produced (that is extracted) at each mine during the period in which they are incurred.

Capitalization of development stripping costs finishes when the commercial production of the mine commences. At that time, all development stripping costs are presented within Mining assets and depreciated on a unit-of-production basis. It is considered that commercial production begins when the production stage of mining operations begins and continues throughout the life of a mine.

(v)    Mining development costs

Mining development costs are the costs associated to the activities related to the establishment of access to the mineral reserve and other preparations for commercial production. These activities often continue during production.

Development expenditures are capitalized and classified as Work in progress. On completion of development, all assets included in Work in progress are individually reclassified to the appropriate category of property, plant and equipment and depreciated accordingly.

(w)    Asset retirement obligations

Ternium records asset retirement obligations (“ARO”) initially at the fair value of the legal or constructive obligation in the period in which it is incurred and capitalizes the ARO by increasing the carrying amount of property, plant and equipment. The fair value of the obligation is determined as the discounted value of the expected future cash flows and is included in Provisions. The liability is accreted to its present value through net financing cost and the capitalized cost is depreciated based in the unit of production method.

(x)    Earnings per share

Earnings per share are calculated by dividing the net income attributable to shareholders by the daily weighted average number of ordinary shares issued during the year, excluding the average number of shares of the parent Company held by the Group. There are no dilutive securities for the periods presented.

(y)    Derivative financial instruments and hedging activities

Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly interest rate swaps, collars, currency forward contracts on highly probable forecast transactions and commodities contracts). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in OCI. Amounts accumulated in OCI are recognized in the income statement in the same period as any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected in the statement of financial position.

For transactions designated and qualifying for hedge accounting, Ternium documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. At December 31, 2021 and 2020, the effective portion of designated cash flow hedges (net of taxes) amounted to $(0.04) million and $(0.23) million, respectively, and were included under "changes in the fair value of derivatives classified as cash flow hedges" line item in the statement of comprehensive income (see Note 26 (a)).

More information about accounting for derivative financial instruments and hedging activities is included in Note 28 "Financial risk management".

(z)    Treasury shares

Acquisitions of treasury shares are recorded at acquisition cost, deducted from equity until disposal. The gains and losses on disposal of treasury shares are recognized under "Reserves" in the consolidated statement of financial position.

(aa)    Cash flow

The consolidated statements of cash flows have been prepared using the indirect method and contain the use of the following expressions and their respective meanings:

a)    Operating activities: activities that constitute ordinary Group revenues, as well as other activities that cannot be qualified as investing or financing.

b)    Investing activities: acquisition, sale or disposal by other means of assets in the long-term and other investments not included in cash and cash equivalents.

c)    Financing activities: activities that generate changes in the size and composition of net equity and liabilities that do not form part of operating activities.

(bb)    Critical Accounting Estimates

The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Management makes estimates and assumptions concerning the future. Actual results may differ significantly from these estimates under different assumptions or conditions.

The principal estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

(1) Goodwill impairment test

Assessment of the recoverability of the carrying value of goodwill requires significant judgment. Management evaluates goodwill allocated to the operating units for impairment on an annual basis or whenever there is an impairment indicator.

Consolidated Financial Statements as of December 31, 2021 and 2020

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

3.    ACCOUNTING POLICIES (continued)

Goodwill is tested at the level of the CGUs. Impairment testing of the CGUs is carried out and the value in use determined in accordance with the accounting policy stated in Note 3(f). The discount rates used for these tests are based on Ternium's weighted average cost of capital adjusted for specific country and currency risks associated with the cash flow projections. The discount rate used at December 31, 2021 was 9.93% and no impairment charge resulted from the impairment test performed. See notes 3(f) and 3(e)(4).

(2)Income taxes

Management calculates current and deferred income taxes according to the tax laws applicable to each subsidiary in the countries in which such subsidiaries operate. However, due to uncertain tax positions, certain adjustments necessary to determine the income tax provision are finalized only after the balance sheet is issued. In cases in which the final tax outcome is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Also, when assessing the recoverability of tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies.

(3)    Loss contingencies

Ternium is subject to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business, including customer claims in which a third party is seeking reimbursement or indemnity. The Company's liability with respect to such claims, uncertain tax positions, lawsuits and other legal proceedings cannot be estimated with certainty. Periodically, management reviews the status of each significant matter and assesses potential financial exposure. If the potential loss from the claim or proceeding is considered probable and the amount can be reasonably estimated, a liability is recorded. Management estimates the amount of such liability based on the information available and the assumptions and methods it has concluded are appropriate, in accordance with the provisions of IFRS. Accruals for such contingencies reflect a reasonable estimate of the losses to be incurred based on information available, including the relevant litigation or settlement strategy, as of the date of preparation of these financial statements. As additional information becomes available, management will reassess its evaluation of the pending claims, lawsuits and other proceedings and revise its estimates. The loss contingencies provision amounts to $83.3 million and $80.6 million as of December 31, 2021 and 2020, respectively,.

(4)Allowance for obsolescence of supplies and spare parts and slow-moving inventory

Management assesses the recoverability of its inventories considering their selling prices or whether they are damaged or have become wholly or partly obsolete.

Net realizable value is the estimated selling price in the ordinary course of business, less the costs of completion and selling expenses.

The Company establishes an allowance for obsolete or slow-moving inventory in connection with finished goods and goods in process. The allowance for slow-moving inventory is recognized for finished goods and goods in process based on management's analysis of their aging. In connection with supplies and spare parts, the calculation is based on management's analysis of their aging, the capacity of such materials to be used based on their levels of preservation and maintenance, and their potential obsolescence due to technological change.

As of December 31, 2021 and 2020, the Company recorded no allowance for net realizable value and $61.5 million and $58.6 million, respectively, as allowance for obsolescence.

(5)Useful lives and Impairment of Property, Plant and Equipment and Other Long-lived Assets

In determining useful lives, management considered, among others, the following factors: age, operating condition and level of usage and maintenance. Management conducted visual inspections for the purpose of (i) determining whether the current conditions of such assets are consistent with normal conditions of assets of similar age; (ii) confirming that the operating conditions and levels of usage of such assets are adequate and consistent with their design; (iii) establishing obsolescence levels and (iv) estimating life expectancy, all of which were used in determining useful lives. Management believes, however, that it is possible that the periods of economic utilization of property, plant and equipment may be different than the useful lives so determined. Furthermore, management believes that this accounting policy involves a critical accounting estimate because it is subject to change from period to period as a result of variations in economic conditions and business performance.

When assessing whether an impairment indicator may exist, the Company evaluates both internal and external sources of information, such as the following:

–whether significant changes with an adverse effect on the entity have taken place during the period, or will take place in the near future, in the technological, market, economic or legal environment in which the entity operates or in the market to which an asset is dedicated;

–whether market interest rates or other market rates of return on investments have increased during the period, and those increases are likely to affect the discount rate used in calculating an asset's value in use and decrease the asset's recoverable amount materially;

–whether the carrying amount of the net assets of the entity is more than its market capitalization;

–whether evidence is available of obsolescence or physical damage of an asset.

–whether significant changes with an adverse effect on the entity have taken place during the period, or are expected to take place in the near future, in the extent to which, or manner in which, an asset is used or is expected to be used. These changes include the asset becoming idle, plans to discontinue or restructure the operation to which an asset belongs, plans to dispose of an asset before the previously expected date, and reassessing the useful life of an asset as finite rather than indefinite; and

–whether evidence is available from internal reporting that indicates that the economic performance of an asset is, or will be, worse than expected.

Considering the economic situation in Argentina as of December 31, 2019, and as of June 30, 2020, the Company tested the recoverability of its investment in Ternium Argentina as of such dates, resulting in no impairment charges to be recognized. As of December 31, 2021 and 2020, no new impairment triggers were detected and, consequently, no impairment test was prepared.

The Company also tested the recoverability of its investments in the rest of the subsidiaries as of June 30, 2020, due to the pandemic, resulting in no impairment charges to be recognized. Considering that no new impairment indicators were identified in the rest of subsidiaries as of December 31, 2021 and 2020, the Company additionally tested the value of the goodwill for impairment, resulting in no impairment charges to be recognized.

In connection with investments in non-consolidated companies and considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company decided to assess the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. As of December 31, 2021, the discount rate used to test the investment in Usiminas for impairment was 11.95%.

(6)    Mining reserve estimates

Reserves are estimates of the amount of product that can be economically and legally extracted from the Company’s mining concessions. In order to estimate reserves, a range of geological, technical and economic factors is required to be considered. Estimating the quantity and/or grade of reserves requires complex and difficult geological judgments to interpret the data. Because the economic assumptions used to estimate reserves change from period to period, and because additional geological data is generated during the course of operations, estimates of reserves may change from period to period.

Changes in reported reserves may affect the Company’s financial results and financial position, including the following:

–Asset carrying amounts may be affected due to changes in estimated future cash flows.

–Depreciation and amortization charges may change where such charges are determined by the units of production basis, or where the useful economic lives of assets change.

–Stripping costs recognized in Mining assets or charged to results may change due to changes in stripping ratios or the units of production basis of depreciation.

–Asset retirement obligations may change where changes in estimated reserves affect expectations about the timing or cost of these activities.

(7)    Post-employment obligation estimates

The Company estimates at each year-end the provision necessary to meet its post-employment obligations in accordance with the advice from independent actuaries. The calculation of post-employment and other employee obligations requires the application of various assumptions. The main assumptions for post-employment and other employee obligations include discount rates, compensation growth rates, pension growth rates and life expectancy.  Changes in the assumptions could give rise to adjustments in the results and liabilities recorded and might have an impact on the post-employment and other employee obligations recognized in the future.

(8)    Valuation of lease liabilities and right-of-use assets

The application of IFRS 16 requires the Company to make judgments that affect the recognition and valuation of the lease liabilities and the right-of-use assets, including the determination of the contracts within the scope of the Standard, the contract term and the interest rate used for the discount of future cash flows.

The lease term determined by the Company generally comprises non-cancellable period of leases contracts, periods covered by an option to extend the lease if the Company is reasonably certain to exercise that option and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option. The same term is applied as economic useful life of right-of-use assets.

3.    ACCOUNTING POLICIES (continued)

The present value of the lease payments is determined using the discount rate representing a risk-free interest rate, adjusted by a spread related to the credit quality of the Company in each location and currency rate in connection with each lease contract.

(9) Change in the functional currency of argentine subsidiaries

The determination of the functional currency requires management to make significant judgments. Ternium Argentina has performed a review of its functional currency and concluded that the currency that most faithfully represents the economics effects of the entity is the U.S. dollar and therefore its functional currency has changed from the local currency to the U.S. dollar. This change was prospective from January 1, 2020, and did not affect the balances at December 31, 2019, nor results or cash flows for the year then ended.

It was based on the following considerations:

–In the last two years, the exchange rate of the Argentine peso has been severely affected by devaluations against the U.S. dollar and Argentina continues to be a highly inflationary economy. These events had very limited impact on sale's price in U.S. dollar;

–In this context, there is also a greater proportion of total production cost in U.S. dollar;

–Furthermore, new global trade restrictions, affecting the international trade of steel along with limited restrictions of imports in Argentina, have led to a greater correlation of local prices to global prices.

–Factors to determine the functional currency were always mixed. However, currently most of revenue and costs of production are negotiated and priced in U.S. dollar.

The change in functional currency of Ternium Argentina significantly reduced the volatility of the Company’s earnings that was due to foreign exchange movements and the application of IAS 29 - Financial Reporting in Hyperinflationary Economies.

(cc)    Application of IAS 29 in financial reporting of Argentine subsidiaries and associates

For the years ended December 31, 2019 and 2018, the Company applied IAS 29 “Financial Reporting in Hyperinflationary Economies”, which requires that the financial statements of entities whose functional currency is that of a hyperinflationary economy to be adjusted for the effects of changes in a suitable general price index and to be expressed in terms of the current unit of measurement at the closing date of the reporting period. Accordingly, the inflation produced from the date of acquisition or from the revaluation date, as applicable, must be computed in the non-monetary items.

In order to conclude on whether an economy is categorized as hyperinflationary under the terms of IAS 29, the Standard details a series of factors to be considered, including the existence of a cumulative inflation rate in three years that approximates or exceeds 100%.

Considering that the significant increase in inflation during 2018, which exceeded the 100% three-year cumulative inflation rate, and that the rest of the indicators did not contradict the conclusion that Argentina should be considered a hyperinflationary economy for accounting purposes, the Company considered that there was sufficient evidence to conclude that Argentina was a hyperinflationary economy under the terms of IAS 29 as from July 1, 2018, and, accordingly, applied IAS 29 as from that date in the financial reporting of its subsidiaries and associates with the Argentine peso as functional currency.

3.    ACCOUNTING POLICIES (continued)

According to this principle, the financial statements of an entity that reports in the currency of a hyperinflationary economy should be stated in terms of the measuring unit current on the date of the financial statements. All statement of financial position amounts that are not stated in terms of the measuring unit current on the date of the financial statements must be restated by applying a general price index. All income statement components must be stated in terms of the measuring unit current on the date of the financial statements, applying the change in the general price index that occurred since the date when revenues and expenses were originally recognized in the financial statements.

The inflation adjustment on the initial balances was calculated by means of conversion factor derived from the Argentine price indexes published by the National Institute of Statistics (“INDEC”). The price index for the year periods ended December 31, 2019 and 2018, were 1.54 and 1.48, respectively.

The main procedures for the above-mentioned adjustment are as follows:

–Monetary assets and liabilities which are carried at amounts current at the balance sheet date are not restated because they are already expressed in terms of the monetary unit current at the balance sheet date.

–Non-monetary assets and liabilities which are not carried at amounts current at the balance sheet date, and components of shareholders' equity are adjusted by applying the relevant conversion factors.

–All items in the income statement are restated by applying the relevant conversion factors.

–The effect of inflation on the Company’s net monetary position is included in the income statement, in Other financial income (expenses), net, under the caption “Inflation adjustment results”.

–The ongoing application of the re-translation of comparative amounts to closing exchanges rates under IAS 21 and the hyperinflation adjustments required by IAS 29 will lead to a difference in addition to the difference arising on the adoption of hyperinflation accounting.

The comparative figures in these consolidated financial statements presented in a stable currency are not adjusted for subsequent changes in the price level or exchange rates. This resulted in an initial difference, arising on the adoption of hyperinflation accounting, between the closing equity of the previous year and the opening equity of the current year. The Company recognized this initial difference directly in equity.

(dd) Climate Change

Ternium is committed to the UN Global Compact Initiative, its sustainable development goals, and the world's efforts to address Climate Change.

The Company is determined to find ways to reduce the carbon footprint of its operations and the steel value chain. In February 2021, Ternium announced a medium-term target to reduce its carbon dioxide emissions intensity rate by 20% in 2030, compared to its 2018 base rate of 1.7 tons of carbon dioxide per ton of steel. The Company’s strategy to achieve this 2030 reduction target consists of a multi-faceted approach that includes increasing the use of renewable energy and the development of energy efficiency strategies, increasing the participation of scrap in the metallic mix, improving the carbon capture capacity at its DRI facilities, replacing coking coal with charcoal and prioritizing lower specific-emission steelmaking technologies.

The Company intends to continue analyzing and developing measures to decarbonize its operations over the longer term. This endeavor will require significant long-term investments, conditioned by technology innovation, cooperation within the value chain, government regulations, and capital availability for decarbonization projects. Factors like access to abundant and affordable clean energy, appropriate energy infrastructure, local and global regulation that guarantee fair trade and carbon capture storage, access to sustainable finance for low emissions steel-making technologies, and changes in consumer behavior will be key in the development of solutions and the outcomes in the next decades.

Given that Ternium’s climate-change-related decarbonization plans span over many years and are subject to significant uncertainty as described above, they have not been included as part of the assumptions used to calculate future cash flows of the recoverable amount of the company’s CGUs. Estimates and assumptions related to the impairment test over long-lived assets and goodwill, useful lives of assets, capital and research and development expenditures, inventory valuation, recovery of deferred tax assets and provisions, and contingent liabilities are based on available information and government regulations in place as of December 31, 2021, as well as on the company’s current short-term investment plans.

4.    SEGMENT INFORMATION

REPORTABLE OPERATING SEGMENTS

The Company is organized in two reportable segments: Steel and Mining.

The Steel segment includes the sales of steel products, which comprises slabs, hot rolled coils and sheets, cold rolled coils and sheets, tin plate, welded pipes, hot dipped galvanized and electro-galvanized sheets, pre-painted sheets, billets (steel in its basic, semi-finished state), wire rod and bars and other tailor-made products to serve its customers’ requirements.

It also includes the sales of energy.

The Steel segment comprises four operating segments: Mexico, Southern Region, Brazil and Other markets. These four segments have been aggregated considering the economic characteristics and financial effects of each business activity in which the entity engages; the related economic environment in which it operates; the type or class of customer for the products; the nature of the products; and the production processes. The Mexico operating segment comprises the Company’s businesses in Mexico. The Southern region operating segment manages the businesses in Argentina, Paraguay, Chile, Bolivia and Uruguay. The Brazil operating segment includes the business generated in Brazil. The Other markets operating segment includes businesses mainly in United States, Colombia, Guatemala and Germany.

The Mining segment includes the sales of mining products, mainly iron ore and pellets, and comprises the mining activities of Las Encinas, an iron ore mining company in which Ternium holds a 100% equity interest and the 50% of the operations and results performed by Peña Colorada, another iron ore mining company in which Ternium maintains that same percentage over its equity interest. Both mining operations are located in Mexico. For Peña Colorada, the Company recognizes its assets, liabilities, revenue and expenses in relation to its interest in the joint operation.

Ternium’s Chief Operating Decision Maker (CEO) holds monthly meetings with senior management, in which operating and financial performance information is reviewed, including financial information that differs from IFRS principally as follows:

–The use of direct cost methodology to calculate the inventories, while under IFRS is at full cost, including absorption of production overheads and depreciation.

–The use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at historical cost (with the FIFO method).

–Other timing and non-significant differences.

Most information on segment assets is not disclosed as it is not reviewed by the CEO.

For 2019, it includes mainly the application of the new tax law in Argentina that enables the tax inflation adjustment. The reduction of the tax rate in Argentina enacted in 2017 was modified in 2019, setting the corporate income tax rate to 30% for the year 2020 and to 25% from the year 2021 going forward.

(2) It includes the recovery of tax credits in Ternium Brasil Ltda.

Income tax expense for the years ended December 31, 2021, 2020 and 2019 differed from the amount computed by applying the statutory income tax rate in force in each country in which the company operates to pre-tax income as a result of the following:

	Year ended December 31,
	2021	2020	2019
Income before income tax	5,764,330	1,159,359	826,564
Income tax expense at statutory tax rate	(1,633,556)	(350,896)	(247,592)

Income tax expense	(1,397,139)	(291,488)	(196,519)

(1) Ternium applies the liability method to recognize deferred income tax on temporary differences between the tax bases of assets and their carrying amounts in the financial statements. By application of this method, Ternium recognizes gains and losses on deferred income tax due to the effect of the change in the value on the tax basis in subsidiaries, which have a functional currency different to their local currency, mainly Mexico and Argentina.

Tax rates used to perform the reconciliation between tax expense (income) and accounting profit are those in effect at each relevant date or period in each applicable jurisdiction.

(a)Usinas Siderurgicas de Minas Gerais S.A. – USIMINAS

As of December 31, 2021, Ternium, through its subsidiaries, owns a total of 242.6 million ordinary shares and 8.5 million preferred shares, representing 20.4% of the issued and outstanding share capital of Usinas Siderurgicas de Minas Gerais S.A. – USIMINAS (“Usiminas”), the largest flat steel producer in Brazil for the energy, automotive and other industries.

Ternium, through its subsidiaries, together with Tenaris S.A.’s Brazilian subsidiary Confab Industrial S.A. (“TenarisConfab”), are part of Usiminas’ control group, comprising the so-called T/T Group. As at December 31, 2021, the Usiminas control group holds, in the aggregate, 483.6 million ordinary shares bound to the Usiminas shareholders’ agreement, representing approximately 68.6% of Usiminas’ voting capital. The Usiminas control group, which is bound by a long-term shareholders’ agreement that governs the rights and obligations of Usiminas’ control group members, is currently composed of three sub-groups: the T/T Group; the NSC Group, comprising Nippon Steel Corporation (“NSC”), Metal One Corporation and Mitsubishi Corporation; and Usiminas’ pension fund Previdência Usiminas. The T/T Group holds approximately 47.1% of the total shares held by the control group (39.5% corresponding to the Ternium entities and the other 7.6% corresponding to TenarisConfab); the NSC Group holds approximately 45.9% of the total shares held by the control group; and Previdência Usiminas holds the remaining 7%.

13.    INVESTMENTS IN NON-CONSOLIDATED COMPANIES (continued)

The corporate governance rules reflected in the Usiminas shareholders agreement provide, among other things, that Usiminas’ executive board will be composed of six members, including the chief executive officer and five vice-presidents, with Ternium and NSC nominating three members each. The right to nominate Usiminas’ chief executive officer alternates between Ternium and NSC at every 4-year interval, with the party that does not nominate the chief executive officer having the right to nominate the chairman of Usiminas’ board of directors for the same 4-year period. The Usiminas shareholders agreement also provides for an exit mechanism consisting of a buy-and-sell procedure—exercisable at any time after November 16, 2022 and applicable with respect to shares held by NSC and the T/T Group—, which would allow either Ternium or NSC to purchase all or a majority of the Usiminas shares held by the other shareholder.

As of December 31, 2021, the closing price of the Usiminas ordinary and preferred shares, as quoted on the BM&F Bovespa Stock Exchange, was BRL 14.51 (approximately $2.60; December 31, 2020: BRL15.69 - $3.02) per ordinary share and BRL15.16 (approximately $2.72; December 31, 2019: BRL14.61 - $2.81) per preferred share, respectively. Accordingly, as of December 31, 2021, Ternium’s ownership stake had a market value of approximately $653.9 million ($756.3 million as of December 31, 2020) and a carrying value of $681.7 million ($422.9 million as of December 31, 2020).

Considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company tested the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. Furthermore, the Company reviews periodically the recoverability of its investment in Usiminas. To determine the recoverable value, the Company estimates the value in use of the investment by calculating the present value of the expected cash flows or its fair value less costs of disposal.

As of December 31, 2021 and 2020, the value of the investment in Usiminas is comprised as follows:

	USIMINAS
Value of investment	As of December 31, 2021	As of December 31, 2020
At the beginning of the year	422,948	486,643
Share of results (1)	379,067	35,580
Other comprehensive income	(38,680)	(93,237)
Dividends	(81,624)	(6,038)
At the end of the year	681,711	422,948

(1) It includes the adjustment of the values associated to the purchase price allocation.

The investment in Usiminas is based in the following calculation:

Usiminas' shareholders' equity	3,897,381
Percentage of interest of the Company over shareholders' equity	20.41	%
Interest of the Company over shareholders' equity	795,444
Purchase price allocation	54,141

During 2012 and 2013, Tenigal entered into several forward starting interest rate swap agreements in order to fix the interest rate to be paid over an aggregate amount of $100 million, at an average rate of 1.92%. As of December 31, 2021, only $6.3 million remain outstanding. These agreements,which became effective during July 2014, will be due on July 2022 and have been accounted for as cash flow hedges. As of December 31, 2021, the after-tax cash flow hedge reserve related to these agreements amounted to $(0.04) million.

Changes in fair value of derivative instruments designated as cash flow hedges for each of the years presented are included below:

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS

Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows.

(i) Tax claims and other contingencies

(a) Companhia Siderúrgica Nacional (CSN) – Tender offer litigation

In 2013, the Company was notified of a lawsuit filed in Brazil by Companhia Siderúrgica Nacional, or CSN, and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and TenarisConfab. The entities named in the CSN lawsuit had acquired a participation in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL 28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group; Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals of São Paulo maintained the understanding of the first instance court. On March 6, 2017, CSN filed a motion for clarification against the decision of the court of appeals, which was rejected on July 19, 2017. On August 18, 2017, CSN filed with the court of appeals an appeal seeking the review and reversal of the decision issued by the court of appeals by the Superior Court of Justice. On March 5, 2018, the court of appeals ruled that CSN’s appeal did not meet the requirements for review by the Superior Court of Justice and rejected such appeal. On May 8, 2018, CSN appealed against such ruling and on January 22, 2019, the court of appeals rejected such appeal and ordered that the case be submitted to the Superior Court of Justice. On September 10, 2019, the Superior Court of Justice declared CSN’s appeal admissible. The Superior Court of Justice will review the case and will then render a decision on the merits. The Superior Court of Justice is restricted to the analysis of alleged violations to federal laws and cannot assess matters of fact.

Ternium continues to believe that all of CSN’s claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator (CVM) in February 2012 and December 2016, and the first and second instance court decisions referred to above. Accordingly, no provision has been recorded in these Consolidated Financial Statements.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(b) Shareholder claims relating to the October 2014 acquisition of Usiminas shares

On April 14, 2015, the staff of the CVM, determined that an acquisition of additional ordinary shares of Usiminas by Ternium Investments made in October 2014, triggered a requirement under applicable Brazilian laws and regulations for Usiminas’ controlling shareholders to launch a tender offer to all non-controlling holders of Usiminas ordinary shares. The CVM staff’s determination was made further to a request by NSSMC and its affiliates, who alleged that Ternium’s 2014 acquisition had exceeded a threshold that triggers the tender offer requirement. In the CVM staff’s view, the 2014 acquisition exceeded the applicable threshold by 5.2 million shares. On April 29, 2015, Ternium filed an appeal to be submitted to the CVM’s Board of Commissioners. On May 5, 2015, the CVM staff confirmed that the appeal would be submitted to the Board of Commissioners and that the effects of the staff’s decision would be stayed until such Board rules on the matter.

On June 15, 2015, upon an appeal filed by NSSMC, the CVM staff changed its earlier decision and stated that the obligation to launch a tender offer would fall exclusively on Ternium. Ternium’s appeal has been submitted to the CVM’s Board of Commissioners,which has no set timeframe to resolve on the matter. In addition, on April 18, 2018, Ternium filed a petition with the CVM’s reporting Commissioner requesting that the applicable threshold for the tender offer requirement be recalculated taking into account the new ordinary shares issued by Usiminas in connection with its 2016 BRL 1 billion capital increase and that, in light of the replenishment of the threshold that would result from such recalculation, the CVM staff’s 2015 determination be set aside.In the event the appeal is not successful, under applicable CVM rules Ternium may elect to sell to third parties the 5.2 million shares allegedly acquired in excess of the threshold, in which case no tender offer would be required.

(c) Potential Mexican income tax adjustment

In March 2015, the Mexican tax authorities, as part of a tax audit to Ternium Mexico with respect to fiscal year 2008, challenged the deduction by Ternium Mexico’s predecessor IMSA Acero of a tax loss arising from an intercompany sale of shares in December 2008. Although the tax authorities have not yet determined the amount of their claim, they have indicated in a preliminary report that they have observations that may result in an income tax adjustment currently estimated at approximately $56.4 million, including interest and fines. Additionally, in September 2018, the Mexican tax authority, as a result of a tax audit for the fiscal year 2011 to Ternium Mexico, as predecessor of APM, objected mainly the deduction of the tax loss remaining for the year 2008, for which the estimated income tax adjustment would be of approximately $27.6 million, including interest and fines.

Ternium Mexico requested an injunction from the Mexican courts against the audit observations for the year 2008 and the fiscal credit of the year 2011, and also filed its defense and supporting documents with the Mexican tax authorities. The injunction for the year 2008 had a favorable resolution to Ternium Mexico in August 2020; consequently, in November 2020, the Mexican tax authorities issued a new preliminary report in which continues having the same observations with different arguments that may result in the same tax adjustment as per the above-included paragraph. The Company, based on the advice of counsel, believes that an unfavorable outcome in connection with this uncertain tax position is not probable and, accordingly, no provision has been recorded in these financial statements.

(d) Fishermen associations’ claims

Civil contingencies include lawsuits brought by a number of fishermen associations on behalf of their associates, alleging that the dredge of Ternium Brasil’s deep-water port has had a negative impact on fish farming and exploitation activities in the Sepetiba Bay area in Rio de Janeiro and that, as a result, fishermen in that area had suffered damages. A provision in the amount of $24.5 million was recorded at the acquisition date in connection with this matter ($8.8 million and $10.9 million as of December 31, 2021 and 2020, respectively).

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(e) Tax assessments relating to the use of certain ICMS tax credits

The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços, or ICMS, is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties.

The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not be qualified as raw materials or intermediary products but as goods for consumption and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed against the Rio de Janeiro State Treasury Office tax assessments and fines. A provision in the amount of $57.7 million was recorded as of the acquisition date in connection with this matter ($32.5 million and $34.9 million as of December 31, 2021 and 2020, respectively).

(f) ICMS deferral tax benefit - Action of Unconstitutionality

On March 31, 2005, through State Law No. 4,529 (Law RJ 4529), the State of Rio de Janeiro granted Ternium Brasil a tax incentive consisting of a deferral of ICMS payable by Ternium Brasil in connection with the construction and operation of the company’s Rio de Janeiro steelmaking complex. The incentive applies in respect of the acquisition of fixed assets and certain raw materials (i.e. iron ore, pellets, alloys, coke, coal and scrap) and significantly reduces input ICMS credit accumulation by Ternium Brasil. The tax incentive was granted for a period of 20 years from the commencement of the construction works for Ternium Brasil’s Rio de Janeiro steel complex.

In 2012, a Brazilian political party filed a direct action of unconstitutionality against Law RJ 4529 before the Brazilian Federal Supreme Court, claiming that the State Law should be declared unconstitutional because the tax incentive granted pursuant to Law RJ 4529 had not been approved by Brazil’s National Council of Fiscal Policy (Conselho Nacional de Política Fazendária, or CONFAZ).

In August 2017, the Brazilian Congress enacted Supplementary Law No. 160/2017, instituting a mechanism through which the States may confirm any ICMS incentives they had granted in prior years without CONFAZ approval. In furtherance of such Supplementary Law, in December 2017 the Brazilian States adopted ICMS Convention 190/2017, establishing the applicable rules and deadlines for confirming such ICMS incentives. In accordance with the ICMS Convention 190/2017, the State of Rio de Janeiro published its list of ICMS incentives, including, among others, the ICMS benefit granted to Ternium Brasil, and filed with CONFAZ all relevant documents concerning such incentives. On July 27, 2018, the Governor of Rio de Janeiro issued Decree No. 46,378, pursuant to which the State of Rio de Janeiro reconfirmed, in accordance with ICMS Convention 190/2017, the ICMS tax benefits listed in its official gazette publication made pursuant to the Convention, including, among others, Ternium Brasil’s ICMS tax benefits.

In October 2018, the State of Rio de Janeiro and the Federation of Industries of the State of Rio de Janeiro filed petitions arguing that the action of unconstitutionality against Law RJ 4529 could not be judged by the Brazilian Federal Supreme Court since, following the revalidation of such law under Supplementary Law No.160/17 and the ICMS Convention 190/2017, such action of unconstitutionality had lost its purpose. On October 20, 2020, the Reporting Justice Minister of the Brazilian Federal Supreme Court in charge of the case ruled that the action of unconstitutionality against Law RJ 4529 was impaired by the supervening loss of its object, and on November 17, 2020, the Reporting Justice Minister’s ruling became final and not subject to any further recourses or appeals.

The tax benefits accumulated under Ternium Brasil’s ICMS incentive amounted to approximately $1,089 million as of the acquisition date of Ternium Brasil on September 7, 2017. In accordance with the guidance in IFRS 3, the Company recorded as of the acquisition date a provision of $651.8 million (including estimated penalties and interest) in connection with this matter, together with an asset of $325.9 million arising from its right to recover 50% of the contingency amount from Thyssenkrupp.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

As at December 31, 2020, both the asset, which expired on September 7, 2020, of $194.1 million recorded in the Company’s financial statements arising from its right to recover 50% of the contingency amount from Thyssenkrupp and the contingent liability of $380.1 million recorded in its financial statements in connection with this matter have been derecognized. Accordingly, the Company recognized in the year ended December 31, 2020, a net gain in the amount of $186.0 million.

(ii) Commitments

The following are Ternium’s main off-balance sheet commitments:

(a) Ternium Argentina signed agreements to cover 80% of its required iron ore, pellets and iron ore fines volumes until December 31, 2024, for an estimated total amount of $890.0 million. Although they do not set a minimum amount or a minimum commitment to purchase a fixed volume, under certain circumstances a penalty is established for the party that fails of:

- 7% in case the annual operated volume is between 70% and 75% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases.

- 15% in case the annual operated volume is lower than 70% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases.

(b) Ternium Argentina also signed various contracts for the provision of natural gas, including Tecpetrol and Energy Consulting Services S.A., both related companies of Ternium, assuming firm commitments for a total of $82.6 million payable until April 2025. Additionally, Ternium Argentina signed contracts for gas transportation with Transportadora de Gas del Norte S.A., a related company of Ternium, assuming firm commitments for a total of $20.6 million payable until April 2028.

(c) Ternium Argentina signed an agreement with Air Liquide Argentina S.A. for the supply of oxygen, nitrogen and argon until 2021, for an aggregate amount of $16.2 million, which is due to terminate in 2037.

(d) On April 24, 2017, Ternium Mexico entered into a 25-year contract (effective as of December 1, 2016, through December 1, 2041) with Techgen, S.A. de C.V. for the supply of 699 MW (which represents 78% of Techgen’s capacity) and covers most of Ternium Mexico’s facilities electricity needs. Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of the seventh contract year (as long as Techgen’s existing or replacing bank facility has been repaid in full), Ternium Mexico has the right to suspend or early terminate the contract if the rate payable under the agreement is higher than the rate charged by Comisión Federal de Electricidad ("CFE") or its successors. Ternium Mexico may instruct Techgen to sell to any affiliate of Ternium Mexico, to CFE, or to any other third party all or any part of unused contracted energy under the agreement and Ternium Mexico will benefit from the proceeds of such sale.

(e) On December 20, 2000, Hylsa (Ternium Mexico’s predecessor) entered into a 25-year contract with Iberdrola Energia Monterrey, S.A. de C.V. (“Iberdrola”), a Mexican subsidiary of Iberdrola Energía, S.A., for the supply of energy to four of Ternium Mexico’s plants. On March 31, 2008, two of those plants were terminated by Iberdrola. The contracted electrical demand as of December 31, 2021, is 51.7 MW. Iberdrola currently supplies approximately 7% of Ternium Mexico’s electricity needs under this contract. Although the contract was to be effective through 2027, on April 28, 2014, Ternium Mexico and Iberdrola entered into a new supply contract and terminated the previous one. In consideration of the termination of the previous contract, Iberdrola has granted Ternium Mexico a credit of $750 thousand per MW of the 111.2 MW originally contracted capacity, resulting over time in a total value of $83.4 million. In addition, Iberdrola agreed to recognize to Ternium México $15.0 million through discounted rates. The above-mentioned credit and discount ended in June 2019 and Ternium Mexico's rates under the contract are now market rates with a 2.5% discount; however, Ternium Mexico is entitled to terminate the contract without penalty. On October 21, 2020, Ternium Mexico decided to terminate the contract effective November 15, 2021; however, this termination date was extended by common agreement with Iberdrola for an additional fixed period and the new effective termination date would be January 31, 2022.

f) Ternium México issued a guarantee letter covering up to approximately $16.6 million of the obligations of Gas Industrial de Monterrey, S.A. de C.V. ("GIMSA"), under the natural gas trading agreement between GIMSA and BP Energía México ("BPEM"). The credit line granted by BPEM in connection with this natural gas trading agreement amounted to approximately $17.0 million. As of December 31, 2021, the outstanding amount under the natural gas trading agreement was $11.5 million, which is below the amount included in the guarantee letter issued by Ternium México.

(g) On June, 2018, Ternium Mexico entered into a loan agreement with a syndicate of banks for a $1,000 million syndicated loan facility for the purpose of financing capital expenditures, the repayment or prepayment of existing debt, and other general corporate purposes. The Company entered the Facility on June 12, 2018, and the final maturity date is on June 12, 2023, being payable in eight consecutive and equal semi-annual installments commencing on December 13, 2019. The main financial covenant that the Facility requires to meet is the consolidated net senior leverage ratio to be not greater than 3.5 to 1.00. During 2019, the facility was fully disbursed ($400 million was disbursed during 2018 and $600 million by the end of June 2019). As of December 31, 2021, the outstanding value of this loan agreement was $250 million and the Company was in compliance with all of its covenants.

(h) Ternium Mexico issued a guarantee letter covering up to approximately $61.8 million of the obligations of Techgen, S.A. de C.V. (“Techgen”), under the Clean Energy Certificates trading agreement between Techgen and Enel Green Power (“ENEL”). The amount equals the remnant balance if Techgen decides to terminate the agreement prior to the expiration date (and decreases as time of the contract passes). The contract was signed on May 25, 2018, and terminates on June 30, 2041.

(i) In June 2008, Ternium Mexico entered into an industrial gas supply agreement with Praxair Mexico for the Guerrero and Juventud facilities until December 2024, for a total amount of $421 million. In 2011, an amendment agreement added the purchase of hydrogen for the Juventud and Universidad facilities valid until April 2025. As of December 31, 2021, the agreement considers a minimum annual oxygen consumption of 96 million cubic meters, valued at approximately $4.5 million per year. The Company is in compliance with the minimum annual quotas established, which represent less than half of the average annual consumption.

(j) On May 9, 2018, Ternium Mexico entered into a 10-year contract (effective as of July 1, 2018) with Kinder Morgan Texas Pipeline L.L.C., Kinder Morgan Tejas Pipeline L.L.C. and Kinder Morgan Border Pipeline L.L.C. for the transportation of natural gas in the United States of America (Texas). The contracted capacity is 60,000 MMBTU/day and the annual cost is approximately $3.7 million.

(k) On December 30, 2019, Ternium Mexico entered into a 15-year contract (effective as of July 1, 2021) with Kinder Morgan Texas Pipeline L.L.C., Kinder Morgan Tejas Pipeline L.L.C. and Kinder Morgan Gas Natural de México S. de R.L. de C.V. for the transportation of natural gas in the United States of America (Texas) and in Mexico.

(l) Techgen is a party to gas transportation capacity agreements with Kinder Morgan Gas Natural de Mexico, S. de R.L. de C.V., Kinder Morgan Texas Pipeline LLC and Kinder Morgan Tejas Pipeline LLC for the whole transportation capacity starting on August 1, 2016, and ending during the second half of 2036. As of December 31, 2021, the outstanding value of this commitment was approximately $206.7 million. Ternium’s exposure under the guarantee in connection with these agreements amounts to $99.2 million, corresponding to the 48% of the agreements’ outstanding value as of December 31, 2021.

The loan agreement dated as of February 13, 2019, amounted to $640 million and the proceeds were used by Techgen to refinance in full all amounts owed under a previous syndicated loan between Techgen and several banks, which funds were used in the construction of the facility. As of December 31, 2021, the outstanding aggregated amount under the stand-by letters of credit was $46.8 million, as a result the amount guaranteed by Ternium was approximately $22.4 million.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(n) During 2006, CSA, the predecessor of Ternium Brasil, has entered into a 15-year contract denominated Contrato de comercialização de energia elétrica no ambiente regulado - CCEAR por disponibilidade to provide electric energy to 24 distributors starting on 2011. Under this contract, Ternium Brasil has to provide 200 MW average per year and the price is adjusted by the Brazilian inflation index. The penalty for not delivering the volume of energy of the contract is the difference between the spot price and the unit variable cost (calculated and published by the Agéncia Nacional de Energía Elétrica), calculated per hour.

(o) Ternium Brasil signed an exclusivity agreement with Vale S.A. for the purchase of iron ore (pellets, sinter feed and lump ore), which is due to terminate in 2029. The total purchased volume, in accordance with the actual production capacity, is of approximately 8.0 million tons per year. Ternium Brasil has not the obligation to take or pay the mentioned volume and only should pay logistic costs in case of not purchasing the contracted volume.

(p) Ternium Brasil, for its activity of energy generation through gas and steam turbines, signed on March 2017 a contract with GE Global Parts and Products GMBH, General Electric International Inc. and Alstom Energia Térmica e Indústria Ltda. for the maintenance services of such turbines (including the supply of spare parts) for a period of 20 years. As of December 31, 2021, the outstanding amount of this commitment was $138.3 million.

(q) Ternium Brasil also signed on November 2007 a contract with Primetals Technologies Brazil Ltda. for the provision of maintenance services at a central workshop for the entire steel mill complex, including caster maintenance for the steel plant. As of December 31, 2021, the outstanding amount of the mentioned services was approximately $44.7 million and is due to terminate on November 2024. Ternium Brasil is currently using more hours than the minimum quantity of contracted hours.

(r) Ternium Brasil is a party to a long-term contract with the Consortium formed by Air Liquide Brasil Ltda., AirSteel Ltda., White Martins Gases Industriais Ltda., White Martins Steel Ltda. and ThyssenKrupp MinEnergy GmbH for the supply of air, oxygen, nitrogen and argon to satisfy the requirements up to January 2029. The outstanding amount was approximately $202.0 million as of December 31, 2021. The contract has minimum daily-required volumes.

(s) Ternium Brasil signed on January 2015 a contract with Naturgy (formerly Companhia Distribuidora de Gás do Rio de Janeiro) for the supply of natural gas, which was due to terminate on December 2019. This agreement was automatically renewed for another two years, is due to terminate on December 2021 and can be interrupted by common agreement due to free market conditions' changes. The outstanding amount was of $24.1 million (or 61.3 million m3) as of December 31, 2021. Ternium Brasil is currently purchasing more than the minimum volume required by the contract, which is 85% of the volume mentioned before.

(t) Ternium Brasil signed on May 2019 a contract with LSI Logistica S.A. for mobile equipment rental. This agreement is due to terminate on May 2024 and the outstanding amount was $7.2 million as of December 31, 2021. The contract only has a penalty in case of anticipated termination.

(u) The acquisition of Ternium Brasil Ltda. was mainly financed through an unsecured 5-year syndicated facility in the principal amount of $1.5 billion granted to the Company’s subsidiary, Ternium Investments S.àr.l., by a syndicate of banks. The facility is to be repaid in eight consecutive and equal semi-annual installments, commencing on March 5, 2019, and has been guaranteed by the Company’s subsidiary, Ternium México, S.A. de C.V. The borrower and the guarantor are subject to certain covenants customary for transactions of this type, including limitations on liens and encumbrances, transactions with affiliates, consolidations and mergers and restrictions on investments. The guarantor is additionally subject to limitations on the sale of certain assets and compliance with a leverage ratio. There are no limitations to the payment of dividends applicable to the borrower or the guarantor, except, with respect to the borrower, upon an event of default under the facility. During 2018 and 2019, the Company made prepayments of principal for $375 million and $725 million, respectively. As of December 31, 2021, the outstanding value of this syndicated facility was $375 million and both the borrower and the guarantor were in compliance with all of its covenants.

27.    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

The following amendments, standards and interpretations have been applied on the year starting January 1, 2021:

International Financial Reporting Standard 7, “Financial Instruments: Disclosures”, International Financial Accounting Standard 9, “Financial Instruments” and International Accounting Standard 39, “Financial Instruments: Recognition and Measurement” - Interest Rate Benchmark Reform

The IASB has issued amendments to IFRS 7 “Financial Instruments: Disclosures”, IFRS 9 “Financial Instruments” and IAS 39 “Financial Instruments: Recognition and Measurement” which provide certain reliefs in relation to interest rate benchmark reforms. The reliefs relate to hedge accounting and have the effect that the reforms should not generally cause hedge accounting to terminate. However, any hedge ineffectiveness should continue to be recorded in the income statement.

The Company's management has assessed the effects of applying these amendments on the Company’s financial statements and has not identified any material impact in the application of these amendments.

International Financial Reporting Standard 16, “Leases” – Amendments on Covid-19-related Rent Concessions

In May 2020, the IASB made an amendment to IFRS 16 “Leases” in the context of the COVID-19 pandemic and its impact on rent concessions granted to lessees. Such concessions might take a variety of forms, including payment holidays and deferral of lease payments, which provides lessees with an option to treat qualifying rent concessions in the same way as they would if they were not lease modifications. In many cases, this will result in accounting for the concessions as variable lease payments in the period in which they are granted. Entities applying the practical expedients must disclose this fact, whether the expedient has been applied to all qualifying rent concessions or, if not, information about the nature of the contracts to which it has been applied, as well as the amount recognized in profit or loss arising from the rent concessions.

The Company's management has assessed the effects of applying this amendment on the Company’s financial statements and has not identified any lease agreements which may be impacted by the application of this amendment.

The following standards, amendments to standards and interpretations are not mandatory for the financial year beginning January 1, 2021, and have not been early adopted:

International Accounting Standard 12, “Income taxes” - Amendments

The IASB has issued amendments to IAS 12 “Income taxes”, which introduce a further exception from the initial recognition exemption. Under the amendments, an entity does not apply the initial recognition exemption for transactions that give rise to equal taxable and deductible temporary differences. Depending on the applicable tax law, equal taxable and deductible temporary differences may arise on initial recognition of an asset and liability in a transaction that is not a business combination and affects neither accounting nor taxable profit.

The Company's management has assessed the effects of applying these amendments on the Company’s financial statements and has not identified any material impact in the application of these amendments.

28. FINANCIAL RISK MANAGEMENT

1)    Financial risk factors

Ternium’s activities expose the Company to a variety of risks: market risk (including the effects of changes in foreign currency exchange rates, interest rates and commodities prices), credit risk and liquidity risk.

Ternium’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the financial performance. Ternium’s subsidiaries may use derivative financial instruments to hedge certain risk exposures.

1.1) Market Risk

(i) Foreign exchange rate risk

Ternium operates and sells its products in different countries, and as a result is exposed to foreign exchange rate volatility. Ternium’s subsidiaries may use derivative contracts in order to hedge their exposure to exchange rate risk derived from their trade and financial operations.

Ternium’s foreign exchange policy is to minimize the negative impact of fluctuations in the value of other currencies with respect to the U.S. dollar. Ternium’s subsidiaries monitor their net cash flows in currencies other than the U.S. dollar, and analyze potential hedging according to market conditions. This hedging can be carried out by netting positions or by financial derivatives. However, regulatory or legal restrictions in the countries in which Ternium’s subsidiaries operate, could limit the possibility of the Company carrying out its hedging policy.

Ternium has foreign operations, whose net assets are exposed to foreign currency translation risk, some of which may impact net income.

The following table shows a breakdown of Ternium’s assessed financial position exposure to currency risk as of December 31, 2021.

Exposure to functional currency	$ million
EU euro (EUR)	(78)
Argentine peso (ARS)	297
Mexican peso (MXN)	(1,255)
Brazilian real (BRL)	66
Colombian peso (COP)	(52)
Other currencies	(1)

TERNIUM S.A.

Consolidated Financial Statements as of December 31, 2021 and 2020

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

28.    FINANCIAL RISK MANAGEMENT (continued)

The main relevant exposures correspond to:

(a)Argentine peso vs. U.S. dollar

If the Argentine peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $3.2 million and $1.0 million as of December 31, 2021 and 2020, respectively.

(b)Mexican peso vs. U.S. dollar

If the Mexican peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $12.5 million and $5.9 million as of December 31, 2021 and 2020, respectively.

(c)Colombian peso vs. U.S. dollar

If the Colombian peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $0.5 million and $0.2 million as of December 31, 2021 and 2020, respectively.

(d) Brazilian real vs. U.S. dollar

If the Brazilian real had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $0.5 million and $1.1 million as of December 31, 2021 and 2020, respectively.

We estimate that if the Argentine peso, Mexican peso, Colombian peso and Brazilian real had weakened simultaneously by 1% against the U.S. dollar with all other variables held constant, total pre-tax income for the year would have been $9.4 million higher ($4.0 million higher as of December 31, 2020), as a result of foreign exchange gains/losses on translation of U.S. dollar-denominated financial position, mainly trade receivables, trade payables, lease liabilities, borrowings and other liabilities.

Considering the same variation of the currencies against the U.S. dollar of all net investments in foreign operations amounting to $681.7 million, the currency translation adjustment included in total equity would have been $6.7 million lower, arising mainly from the adjustment on translation of the equity related to the Brazilian real during the year 2021.

(ii) Interest rate risk

Ternium manages its exposure to interest rate volatility through its financing alternatives and hedging instruments. Borrowings issued at variable rates expose the Company to the risk of increased interest expense in the event of a raise in market interest rates, while borrowings issued at fixed rates expose the Company to a variation in its fair value. The Company’s interest-rate risk mainly arises from long-term borrowings that bear variable-rate interest that is partially fixed through different derivative transactions, such as interest rate swaps.

Ternium’s nominal weighted average interest rate for its debt instruments, which do not include neither the effect of derivative financial instruments, nor the devaluation of the local currencies, was 1.45% and 1.43% as of December 31, 2021 and 2020, respectively. These rates were calculated using the rates set for each instrument in its corresponding currency and weighted using the dollar-equivalent outstanding principal amount of each instrument.

Ternium’s total variable interest rate debt amounted to $1,304 million (88.2% of total borrowings) at December 31, 2021 and $1,593 million (92.5% of total borrowings) at December 31, 2020.

If interest rates on the aggregate average notional of U.S. dollar denominated borrowings held during 2021, excluding borrowings with derivatives contracts mentioned in Note 21 (a), had been 100s basis points higher with all other variables held constant, total pre-tax income for the year ended December 31, 2021 would have been $17.3 million lower ($20.3 million lower as of December 31, 2020).

Effect of IBOR reform

Reform and replacement of various inter-bank offered rates (‘IBORs’) has become a priority for regulators. Most IBOR rates stopped being published by December 31, 2021, while certain U.S. dollar LIBOR rates would stop being published by June 30, 2023.

Consolidated Financial Statements as of December 31, 2021 and 2020

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

28.    FINANCIAL RISK MANAGEMENT (continued)

Ternium would not be required to transition to alternative interest rate benchmarks as of December 31, 2021, as most of its outstanding borrowings with floating interest rates based in U.S. dollar LIBOR rates will be fully repaid before June 30, 2023 and such LIBOR rates will continue to be published until such date. All newly transacted floating rate financial liabilities will be linked to an alternative benchmark rate (e.g. SOFR + spread adjustments).

Under any specific requests of any of its counterparties in these outstanding borrowings, Ternium will negotiate to perform a transition of legacy IBOR-based financial instruments to alternative benchmark interest rates. The Company has prepared a sensitivity analysis considering this situation and concluded that no material impacts could derive from this change. The Company is also enhancing its IT systems and internal processes to ensure smooth transition from IBOR to alternative benchmark interest rates.

1.2) Credit risk

Credit risk arises from cash and cash equivalents, deposits with banks and financial institutions, as well as credit exposures to customers, including outstanding receivables and committed transactions. Ternium’s subsidiaries have credit guidelines in place to ensure that derivative and treasury counterparties are limited to high credit quality financial institutions.

Ternium invests in financial assets with a minimum credit rating of investment grade established by an international qualification agency renowned in the financial market, in line with corporate investment portfolio policies. Approximately 57.3% of the Company’s liquid financial assets correspond to investment grade rated instruments as of December 31, 2021, in comparison with approximately 61.1% as of December 31, 2020. The investments in financial assets are as follows:

	At December 31, 2021	At December 31, 2020
Cash and cash equivalents	1,276,605	537,882
Other Investments - Current and Non-Current	1,357,485	816,157
Fixed Income (time-deposit, zero-coupon bonds, commercial papers)	863,416	579,917
Deposit certificates	710,996	451,857
Commercial papers	92,729	128,060
Other	59,691	—
Bonds and other fixed income	490,806	233,611
Non - U.S. government securities	367,333	135,671
Corporate securities	123,473	97,940
Other notes	3,263	2,629

    

Ternium has no significant concentrations of credit risk from customers. No single customer accounts for more than ten percent of Ternium’s sales. Ternium’s subsidiaries have policies in place to ensure that sales are made to customers with an appropriate credit history, and that credit insurances, letters of credit or other instruments are requested to reduce credit risk whenever deemed necessary. The subsidiaries maintain allowances for potential credit losses. The utilization of credit limits is regularly monitored.

Trade and other receivables are carried at face value less allowance for doubtful accounts, if applicable. This amount does not differ significantly from fair value. The other receivables do not contain significant impaired assets.

As of December 31, 2021, trade receivables total $1,767.4 million ($918.4 million as of December 31, 2020). These trade receivables are collateralized by guarantees under letter of credit and other bank guarantees of $30.3 million ($1.3 million as of December 31, 2020), credit insurance of $800.1 million ($422.8 million as of December 31, 2020) and other guarantees of $8.4 million ($7.3 million as of December 31, 2020).

As of December 31, 2021, trade receivables of $1,681.5 million ($892.3 million as of December 31, 2020) were fully performing.

28.    FINANCIAL RISK MANAGEMENT (continued)

Fair Value by Hierarchy

Following the requirements contained in IFRS 13, Ternium categorizes each class of financial instrument measured at fair value in the statement of financial position into three levels, depending on the significance of the judgment associated with the inputs used in making the fair value measurements:

–Level 1 comprises financial assets and financial liabilities whose fair values have been determined on the basis of quoted prices (unadjusted) in active markets for identical assets or liabilities.

–Level 2 includes financial assets and financial liabilities for which fair values have been estimated using inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

–Level 3 comprises financial instruments for which inputs to estimate fair value of the assets or liabilities are not based on observable market data (unobservable inputs).

The following table presents the assets and liabilities that are measured at fair value as of December 31, 2021 and 2020:

	Fair value measurement as of December 31, 2021 (in $ thousands):
Description	Total	Level 1	Level 2	Level 3 (*)
Financial assets at fair value through profit or loss / OCI
Cash and cash equivalents	692,529	692,529	—	—
Other investments	735,654	668,056	39,777	27,821
Derivative financial instruments	4,353	—	4,353	—
Total assets	1,432,536	1,360,585	44,130	27,821
Financial liabilities at fair value through profit or loss / OCI
Derivative financial instruments	1,889	—	1,889	—
Total liabilities	1,889	—	1,889	—

	Fair value measurement as of December 31, 2020 (in $ thousands):
Description	Total	Level 1	Level 2	Level 3 (*)
Financial assets at fair value through profit or loss / OCI
Cash and cash equivalents	259,020	259,020	—	—
Other investments	236,240	233,611	—	2,629

Total assets	496,832	492,631	1,572	2,629
Financial liabilities at fair value through profit or loss / OCI
Derivative financial instruments	6,358	—	6,358	—
Total liabilities	6,358	—	6,358	—

(*) The fair value of financial instruments classified as level 3 is not obtained from observable market information, but from measurements of the asset portfolio at market value provided by the fund manager. The evolution of such instruments during the years ended December 31, 2021 and 2020, corresponds to the initial investment and to the changes in its fair value, as follows:.

	Guarantee fund companies		Non - U.S. government securities		Corporate securities

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

28.    FINANCIAL RISK MANAGEMENT (continued)

There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy and there were no transfers from Level 1 and Level 2 to Level 3.

The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by Ternium is the current mid price. These instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.

The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is determined by using valuation techniques which maximize the use of observable market data when available and rely as little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the instrument is included in Level 2. Ternium values its assets and liabilities included in this level using mid prices, interest rate curves, broker quotations, current exchange rates and forward rates volatilities obtained from market contributors as of the valuation date.

If one or more of the significant inputs are not based on observable market data, the instruments are included in Level 3. Ternium values its assets and liabilities in this level using observable market inputs, information provided by fund managers and management assumptions which reflect the Company’s best estimate on how market participants would price the asset or liability at measurement date.

3)    Accounting for derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized in the statement of financial position at cost and subsequently measured at fair value. Changes in fair value are disclosed under “Other financial income (expenses), net” line item in the income statement. Ternium does not hedge its net investments in foreign entities.

Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly interest rate swaps). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized within other comprehensive income. Amounts accumulated in other comprehensive income are recognized in the income statement in the same period than any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected on the statement of financial position.

For transactions designated and qualifying for hedge accounting, Ternium documents at inception the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. At December 31, 2021, the effective portion of designated cash flow hedges amounts to $(0.04) million (net of taxes) and is included as “Cash flow hedges” line item in the statement of comprehensive income.

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

28.    FINANCIAL RISK MANAGEMENT (continued)

The fair values of various derivative instruments used for hedging purposes are disclosed in Note 21. The full fair value of a hedging derivative is classified as a non-current asset or liability when the remaining maturity of the hedged item is more than 12 months and as a current asset or liability when the remaining maturity of the hedged item is less than 12 months.

Changes in the fair value of any derivative instruments that do not qualify for hedge accounting under IAS 39 are recognized immediately in the income statement.

4)    Fair value estimation

The estimated fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

For the purpose of estimating the fair value of financial assets and liabilities with maturities of less than one year, the Company uses the market value less any estimated credit adjustments. For other investments, the Company uses quoted market prices.

As most borrowings incorporate floating rates that approximate market rates and the contractual repricing occurs mostly every one month, the fair value of the borrowings approximates their carrying amount and it is not disclosed separately.

In assessing the fair value of derivatives and other financial instruments, Ternium uses a variety of methods, including, but not limited to, estimated discounted value of future cash flows using assumptions based on market conditions existing at each year end.

29.    THE COVID-19 PANDEMIC AND ITS IMPACT ON TERNIUM

A novel strain of coronavirus (SARS-CoV-2) was reported to have surfaced in China in December 2019, spreading to the rest of the world in the first quarter of 2020. In March 2020, the World Health Organization declared COVID-19, the disease caused by the SARS-CoV-2 virus, a global pandemic. The COVID-19 outbreak impacted economic activity worldwide.

In order to safeguard the health and safety of its employees, customers and suppliers, Ternium continues to apply preventive measures, including remote working under a hybrid work scheme for salaried employees, implementing a special operations protocol to ensure social distancing and providing medical assistance and supplies to onsite employees. As of the date of these consolidated financial statements, remote work and other work arrangements have not materially adversely affected Ternium's ability to conduct operations. In addition, these alternative working arrangements have not adversely affected our financial reporting systems, internal control over financial reporting or disclosure controls and procedures.

Even though the main negative effects of the pandemic in steel demand are behind us, and as of the issue date of these consolidated financial statements all of Ternium’s industrial facilities continued working at normal production levels, there remains considerable uncertainty about the future duration and extent of the pandemic with new and more contagious variants of the virus appearing and the vaccination programs not yet completed around the world.

29.    THE COVID-19 PANDEMIC AND ITS IMPACT ON TERNIUM (continued)

With total cash and cash equivalents and other current and non-current investments less borrowings of $1.2 billion as of December 31, 2021 and a manageable debt amortization schedule, Ternium has in place non-committed credit facilities and management believes it has adequate access to the credit markets. Considering its financial position and the funds provided by operating activities, management believes that the Company has sufficient resources to satisfy its current working capital needs and service its debt. Management also believes that Ternium's liquidity and capital resources give adequate flexibility to manage the capital spending programs and address short-term changes in business conditions, and that it is unlikely that Ternium will not be able to meet its financial covenants. Similarly, management does not expect to incur any material COVID-19-related contingencies.

30.    FOREIGN EXCHANGE RESTRICTIONS IN ARGENTINA

Ternium’s Argentine subsidiary, Ternium Argentina S.A., is currently operating in a complex and volatile economic environment. Beginning in September 2019, the Argentine government has imposed and continues to impose significant restrictions on foreign exchange transactions. Restrictions have tightened over time. These measures, however, have not had a significant effect on Ternium Argentina’s ability to purchase U.S. dollars at the prevailing official exchange rate for all of its imports of goods and for the acquisition of services from unrelated parties. By contrast, access to the Argentine foreign exchange market to distribute dividends or to pay royalties to related parties at the prevailing official exchange rate generally requires prior Argentine Central Bank approval, which is rarely, if ever, granted. In March 2022, the Argentine government imposed further restrictions to access the foreign exchange market for payment of imports. If such restrictions are maintained, or are further tightened, Ternium Argentina could be restricted from making payment of imports for key steelmaking inputs which would adversely affect its operations, or would need to resort to alternative, more expensive arrangements, which would affect its results of operations.

Ternium Argentina stated in its annual accounts as of and for the year ended December 31, 2021, that revenues amounted to $3,425 million (2020: $1,823 million), net profit from continuing operations to $930 million (2020: $268 million), total assets to $4,798 million (2020: $3,273 million), total liabilities to $541 million (2020: $430 million) and shareholders’ equity to $4,257 million (2020: $2,843 million).

Ternium Argentina’s cash and cash equivalents and other investments amounted to $965 million as of December 31, 2021:

- $306 million in Argentine pesos-denominated instruments, mainly inflation-linked financial instruments ($155 million), such as bonds and bills adjusted by CER (Reference Stabilization Coefficient), and mutual funds ($135 million).

- $242 million in Argentine pesos-denominated instruments with underlying assets to the U.S. dollar (Cedears - Argentine deposit certificates)

- $417 million in U.S. dollars-denominated instruments, mainly sovereign bonds issued by the Argentine State and payable in U.S. dollars, national Treasury bonds related to the official exchange rate and negotiable obligations and promissory notes issued by national export driven companies in U.S. dollars and payable in Argentine pesos.

Ternium Argentina’s financial position in ARS as of December 31, 2021, amounted to $612 million in monetary assets and $290 million in monetary liabilities. All of Ternium Argentina’s ARS-denominated assets and liabilities are valued at the prevailing official exchange rate. Although most of Ternium Argentina’s cash holdings are either denominated or payable in ARS, this exposure to the ARS as of December 31, 2021, was diminished due to hedging strategies using derivative instruments amounting to $100 million.

As the context of volatility and uncertainty remains in place as of the issue date of these consolidated financial statements, additional regulations that could be imposed by the Argentine government could further restrict Ternium Argentina’s ability to access the official foreign exchange market.

31. SALE OF PARTICIPATION OF TERNIUM ARGENTINA S.A. IN TERNIUM MEXICO S.A. DE C.V. AND PROSID INVESTMENTS S.A. TO TERNIUM INTERNACIONAL ESPAÑA S.L.

On December 21, 2021, Ternium Argentina S.A. (“Ternium Argentina”) received from Ternium Internacional España S.L. (“Ternium España”) an offer consisting of:

(i) The purchase of all the shares that Ternium Argentina owns in Ternium Mexico S.A. de C.V. (“Ternium Mexico”) (103,770,972 shares, representing 28.73% of the capital stock) for a value of $1,000 million.

(ii) The purchase of all the shares that the Company owns in Prosid Investments S.A. (“Prosid Investments”) (1,094,288,000 shares, representing 99.9% of the capital stock) for the equivalent of the market value of its assets, mainly including cash and the transfer and assignment of its participation in Usiminas.

The operation is subject to the following conditions:

• The favorable opinion of the Audit Committee and the recommendation by the Ternium Argentina Board of Directors, in whose voting the non-independent directors will not participate.

• The conclusion by the buyer and seller of the contracts necessary for the implementation and completion of the operation.

• The payment of dividends simultaneously with the payment for the shares in an amount of $900 million.

• The approval of the Ordinary Shareholders' Meeting of Ternium Argentina, with the abstention of Ternium España, with the valid votes of at least the 95% of the shareholders.

Additionally, the operation is subject to the fact that, until the closing date, some facts or circumstances (resolution conditions) mentioned in the offer, related to legal events, claims, administrative or governmental regulations, that prevent, limit or impose certain restrictions, or additional payments to those foreseen.

On February 25, 2022, the Board of Directors of Ternium Argentina S.A. requested to Ternium Internacional España S.L. to review the value and conditions of the offer.

On March 18, 2022, the Company’s board of directors resolved to decline Ternium Argentina’s request to improve the terms and conditions of its previously disclosed offer to acquire the minority participation in Ternium Mexico that Ternium does not own directly.

32. SUBSEQUENT EVENTS - THE RUSSIA-UKRAINE ARMED CONFLICT

On February 24, 2022, Russia launched a military attack on Ukraine. In response, the United States, the United Kingdom, and the European Union, among other countries, have imposed a wave of sanctions against certain Russian institutions, companies and citizens. As a result of the armed conflict and related sanctions, energy prices have spiked and foreign trade transactions involving Russian and Ukrainian counterparties have been severely affected.

Russia has a significant participation in the international trade of steel slabs, iron ore pellets, metallurgical coal, pulverized coal for injection, which are relevant inputs for Ternium’s operations. In addition, Ukraine has a relevant participation in the international trade of steel slabs and iron ore pellets. The availability and pricing of these inputs in the international markets are expected to be volatile and could result in limitations to Ternium’s production levels and higher costs, affecting the Company’s profitability and results of operations. As a result of the economic sanctions imposed on Russia, Ternium or its contractors (including shipping companies) may not be able to continue purchasing or transporting products from, or making payments to, Ukrainian or Russian suppliers or counterparties; and the Company may not be able to promptly procure such raw materials from other suppliers, or may be required to purchase raw materials at increased prices.

The General Shareholders’ Meeting has authorized the Board of Directors, for a period starting on the date of the Extraordinary General Meeting of Shareholders held on 5 June 2020 and ending on the fifth anniversary of the date of the publication in the RESA of the deed recording the minutes of such meeting, to waive, suppress or limit any pre-emptive subscription rights of shareholders provided for by law to the extent it deems such waiver, suppression or limitation advisable for any issue or issues of shares within the authorized share capital, and has waived any pre-emptive subscription rights provided for by law and related procedures;

Les actions sont émises avec matricules, à condition, toutefois, que les actions puissent être enregistrées sans matricules dans des comptes de titres fongibles ouverts auprès d’institutions financières ou d’autres dépositaires professionnels. Les actions détenues en dépôt ou sur un compte auprès d’une telle institution financière ou d’un tel dépositaire professionnel seront inscrites sur un compte ouvert au nom du déposant et peuvent être transférées d’un compte à un autre, que ce compte soit détenu par une, la même ou une autre institution financière ou dépositaire professionnel. Le déposant dont les actions sont détenues sur de tels comptes de titres fongibles aura les mêmes droits et obligations que si ses actions étaient inscrites au registre d’actions nominatives de la Société.

PAGE 17

Le transfert des actions nominatives, porté au registre d’actions nominatives et qui ne sont pas détenues sur des comptes de titres fongibles, sera réalisé par une déclaration écrite de transfert signée par le cédant et le cessionnaire ou par leurs mandants. Le Conseil d’Administration peut accepter et inscrire dans le registre un transfert sur base de tout document(s) approprié(s) constatant le transfert entre le cédant et le cessionnaire.

Pour l’exercice des droits à son encontre ainsi que pour l’exercice des droits de vote aux assemblées générales et de tous droits octroyés aux actionnaires, la Société ne reconnaîtra qu’un seul et unique propriétaire par action. S’il existe plusieurs propriétaires d’une action, la Société aura le droit de suspendre l’exercice de tous les droits y attachés jusqu’à ce qu’une personne ait été désignée comme étant propriétaire de cette action à l’égard de la Société ou jusqu’à ce qu’un seul représentant des propriétaires ait été nommé pour les représenter à l’égard de la Société.

Les droits et obligations attachés à toute action se transmettront à tout cessionnaire.

Toutes communications et notifications devant être faites aux actionnaires nominatifs seront considérées comme valablement faites à la dernière adresse communiquée par l’actionnaire à la Société.

Alternative performance measures

Free cash flow

Free cash flow (FCF) is a measure of financial performance, calculated as operating cash flow less capital expenditures. FCF represents the cash that a company is able to generate after spending the money required to maintain or expand its asset base. FCF is calculated in the following manner:

Free cash flow = net cash provided by operating activities – capital expenditures.

	For the year ended December 31,
U.S. dollar million	2021	2020	2019
Net cash provided by operating activities	2,677	1,761	1,647
Less: capital expenditures	(524)	(560)	(1,052)
Free cash flow	2,154	1,201	595

Net (cash) debt position

This is the net balance of borrowings less cash and cash equivalents and other investments (current and non-current), adjusted to exclude other investments in SGR (non-current). It provides a summary of the financial solvency and liquidity of the company. Net (cash) debt is widely used by investors and rating agencies and creditors to assess the company’s leverage, financial strength, flexibility and risks. Net (cash) debt is calculated in the following manner:

Net (cash) debt = borrowings (current and non-current) – cash and cash equivalents – other investments (current and non-current).

	For the year ended December 31,
U.S. dollar million	2021	2020	2019
Borrowings (current and non-current)	1.5	1.7	2.2
Less: cash and cash equivalents1	(1.3)	(0.5)	(0.5)
Less: other investments (current and non-current)1	(1.4)	(0.8)	(0.2)
Net (cash) debt position	(1.2)	0.4	1.5

GENERAL INFORMATION

1.    GENERAL INFORMATION

Ternium S.A. (the “Company” or “Ternium”), was incorporated on December 22, 2003 to hold investments in flat and long steel manufacturing and distributing companies. The Company has an authorized share capital of a single class of 3.5 billion shares having a nominal value of $1.00 per share. As of December 31, 2021, there were 2,004,743,442 shares issued. All issued shares are fully paid.

Ternium’s American Depositary Shares ("ADSs") trade on the New York Stock Exchange under the symbol “TX”.

The Company was initially established as a public limited liability company (société anonyme) under Luxembourg’s 1929 holding company regime. Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929 regime (including the Company) were exempt from Luxembourg corporate and withholding tax over dividends distributed to shareholders.

On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, effective as from that date, the Company is subject to all applicable Luxembourg taxes (including, among others, corporate income tax on its worldwide income) and its dividend distributions will generally be subject to Luxembourg withholding tax. However, dividends received by the Company from subsidiaries in high income tax jurisdictions, as defined under Luxembourg law, will continue to be exempt from corporate income tax in Luxembourg under Luxembourg’s participation exemption.

As part of the Company’s corporate reorganization in connection with the termination of Luxembourg’s 1929 holding company regime, on December 6, 2010, the Company contributed its equity holdings in all its subsidiaries and all its financial assets to its Luxembourg wholly-owned subsidiary Ternium Investments S.à.r.l., or Ternium Investments, in exchange for newly issued corporate units of Ternium Investments. As the assets contributed were recorded at their historical carrying amount in accordance with Luxembourg GAAP, the Company’s December 2010 contribution of such assets to Ternium Investments resulted in a non-taxable revaluation of the accounting value of the Company’s assets under Luxembourg GAAP. The amount of the December 2010 revaluation was equal to the difference between the historical carrying amounts of the assets contributed and the value at which such assets were contributed and amounted to $4.0 billion. However, for the purpose of these consolidated financial statements, the assets contributed by Ternium to its wholly-owned subsidiary Ternium Investments were recorded based on their historical carrying amounts in accordance with IFRS, with no impact on the financial statements.

Following the completion of the corporate reorganization, and upon its conversion into an ordinary Luxembourg holding company, the Company voluntarily recorded a special reserve exclusively for tax-basis purposes. As of December 31, 2021 and 2020, this special tax reserve amounted $5.8 billion and $6.3 billion, respectively. The Company expects that, as a result of its corporate reorganization, its current overall tax burden will not increase, as all or substantially all of its dividend income will come from high income tax jurisdictions.

Disclosure of significant accounting policies [Abstract]

ACCOUNTING POLICIES

ACCOUNTING POLICIES

The following is a summary of the principal accounting policies followed in the preparation of these Consolidated Financial Statements:

(a)Group accounting

(1)    Subsidiary companies and transactions with non-controlling interests

Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at the fair values at the acquisition date. Indemnification assets are recognized at the same time that the Company recognizes the indemnified item and measures them on the same basis as the indemnified item, subject to the need for a valuation allowance for uncollectible amounts. The Company measures the value of a reacquired right recognized as an intangible asset on the basis of the remaining contractual term of the related contract regardless of whether market participants would consider potential contractual renewals in determining its fair value.

On an acquisition-by-acquisition basis, the Company recognizes any non-controlling interest in the acquiree at the non-controlling interest's proportionate share of the acquiree's net assets.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the Company's share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

The measurement period is the earlier of the date that the acquirer receives the information that it is looking for or cannot obtain the information and one year after the acquisition date. Where the accounting for a business combination is not complete by the end of the reporting period in which the business combination occurred provisional amounts are reported.

The Company treats transactions with non-controlling interests as transactions with equity owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

3.    ACCOUNTING POLICIES (continued)

When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the group. However, the fact that the functional currency of some subsidiaries is their respective local currency, generates some financial gains (losses) arising from intercompany transactions, that are included in the consolidated income statement under Other financial expenses, net.

(2)    Investments in non-consolidated companies

Associated companies are those entities in which Ternium has significant influence, but which it does not control.

Joint arrangements are understood as combinations in which there are contractual agreements by virtue of which two or more companies hold an interest in companies that undertake operations or hold assets in such a way that any financial or operating decision is subject to the unanimous consent of the partners. A joint arrangement is classed as a joint operation if the parties hold rights to its assets and have obligations in respect of its liabilities or as a joint venture if the venturers hold rights only to the investee's net assets.

Investments in non-consolidated companies (associated companies and joint ventures) are accounted for using the equity method of accounting. Under this method, interests in joint ventures and associates are initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Company’s share of the post-acquisition profits or losses in the income statement, and its share of post-acquisition changes in reserves recognized in reserves and in other comprehensive income in the income statement. Unrealized gains on transactions among the Company and its non-consolidated companies are eliminated to the extent of the Company’s interest in such non-consolidated companies; unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. When the Company’s share of losses in a non-consolidated company equals or exceeds its interest in such non-consolidated company, the Company does not recognize further losses unless it has incurred obligations or made payments on behalf of such non-consolidated company.

The Company’s investment in associates and joint ventures includes notional goodwill identified on acquisition.

The Company determines at each reporting date whether there is any objective evidence that the investment is impaired. If this is the case, the group calculates the amount of impairment as the difference between the recoverable amount of the investment and its carrying value and recognizes the amount within “Equity on earnings (losses) of non-consolidated companies”.

3.    ACCOUNTING POLICIES (continued)

(b)Foreign currency translation

(1)Functional and presentation currency

Items included in the financial statements of each of the Company's subsidiaries and associated companies are measured using the currency of the primary economic environment in which the entity operates (the "functional currency"). Except for the non-consolidated companies whose functional currencies are their local currencies, Ternium determined that the functional currency of its subsidiaries is the U.S. dollar. Although Ternium is located in Luxembourg, it operates in several countries with different currencies. The $ is the currency that best reflects the economic substance of the underlying events and circumstances relevant to Ternium as a whole.

(2)    Subsidiary companies

The results and financial position of all the group entities (except for the ones which operated in a hyperinflationary economy) that have a functional currency different from the presentation currency, are translated into the presentation currency as follows:

(i) assets and liabilities are translated at the closing rate of each statement of financial position;

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

(iii) all resulting translation differences are recognized within other comprehensive income.

In the case of a sale or other disposition of any such subsidiary, any accumulated translation differences would be recognized in the income statement as part of the gain or loss on sale.

(3)    Transactions in currencies other than the functional currency

Transactions in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation where items are re-measured.

At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency are translated using the closing rates, (ii) non-monetary items that are measured in terms of historical cost in a currency other than the functional currency are translated using the exchange rates prevailing at the date of the transactions; and (iii) non-monetary items that are measured at fair value in a currency other than the functional currency are translated using the exchange rates prevailing at the date when the fair value was determined.

Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than the functional currency are recorded as gains and losses from foreign exchange and included in "Other financial income (expenses), net" in the consolidated income statement, except when deferred in equity as qualifying cash flow hedges and qualifying net investment hedges. Translation differences on non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the "fair value gain or loss," while translation differences on non-monetary financial assets such as equities classified as fair value through other comprehensive income are included in other gains/(losses).

3.    ACCOUNTING POLICIES (continued)

(c)Financial instruments

Non derivative financial instruments

Non derivative financial instruments comprise investments in equity and debt securities, trade and other receivables, cash and cash equivalents, loans and borrowings, and trade and other payables.

The Company classifies its financial instruments in the following measurement categories:

–Amortized cost: instruments that are held for collection or repayment of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. Interest income and expenses from these financial instruments are included in finance income or expense using the effective interest rate method. Any gain or loss arising on derecognition is recognized directly in profit or loss and presented in finance income or expense, together with foreign exchange gains and losses. Impairment losses are presented as separate line items in the statement of profit or loss.

–Fair value through other comprehensive income (“FVOCI”): financial assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity to profit or loss and recognized in other gains/(losses). Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses) and impairment expenses are presented as separate line item in the statement of profit or loss.

–Fair value through profit or loss (“FVPL”): financial instruments that do not meet the criteria for amortized cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognized in profit or loss and presented net within other gains/(losses) in the period in which it arises.

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

For financial instruments measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the group has made an irrevocable election at the time of initial recognition to account for the equity investment at FVOCI.

At initial recognition, the Company measures a financial instrument at its fair value plus, in the case of a financial instrument not at FVPL, transaction costs that are directly attributable to the acquisition of the financial instrument. Transaction costs of financial instruments carried at FVPL are expensed in profit or loss. Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset.

3.    ACCOUNTING POLICIES (continued)

The classification depended on the nature and purpose of the financial assets and was determined at the time of initial recognition.

Financial assets and liabilities were recognized and derecognized on the settlement date.

Financial assets were initially measured at fair value, net of transaction costs, except for those financial assets classified as financial assets at fair value through profit or loss.

Financial liabilities, including borrowings, were initially measured at fair value, net of transaction costs and subsequently measured at amortized cost using the effective interest method, with interest expense recognized on an effective yield basis.

Impairment of financial assets

The Company assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk.

For trade receivables, the Company applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognized from initial recognition of the receivables, see note 3 (i) for further details.

For loans and receivables category and for held-to-maturity investments, the amount of the loss was measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset's original effective interest rate. The carrying amount of the asset was reduced and the amount of the loss was recognized in the consolidated income statement.

If, in a subsequent period, the amount of the impairment loss decreased and the decrease could be related objectively to an event occurring after the impairment was recognized, the reversal of the previously recognized impairment loss was recognized in the consolidated income statement.

Derivative financial instruments

Information about accounting for derivative financial instruments and hedging activities is included in Note 28 "Financial Risk management" and Note 3 (y).

3.    ACCOUNTING POLICIES (continued)

(d)Property, plant and equipment

(1) Property, plant and equipment

Land and buildings comprise mainly factories and offices. All property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation and accumulated impairment (if applicable), except for land, which is carried at acquisition cost less accumulated impairment (if applicable). There are no material residual values for property, plant and equipment items.

Major overhaul and rebuilding expenditures are recognized as a separate asset when future economic benefits are expected from the item, and the cost can be measured reliably.

Ordinary maintenance expenses on manufacturing properties are recorded as cost of products sold in the period in which they are incurred.

Where a tangible fixed asset comprises major components having different useful lives, these components are accounted for as separate items. Spare parts are included in property, plant and equipment.

Depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to amortize the cost of each asset to its residual value over its estimated useful life as follows:

Land	No depreciation
Buildings and improvements	10-50 years
Production equipment	5-40 years
Vehicles, furniture and fixtures and other equipment	3-20 years

Property, plant and equipment used in mining activities are depreciated over its useful life or over the remaining life of the mine if shorter and there is no alternative use possible.

The assets' useful lives are reviewed, and adjusted if appropriate, at each year end. The re-estimation of assets useful lives by the Company did not materially affect depreciation charges in 2021, 2020 and 2019.

Gains and losses on disposals are determined by comparing the proceeds with the corresponding carrying amounts and are included in the income statement.

If the carrying amount of an asset were greater than its estimated recoverable amount, it would be written down to its recoverable amount (see Note 3 (f) "Impairment").

Amortization charges are included in cost of sales, selling, general and administrative expenses.

3.    ACCOUNTING POLICIES (continued)

(2) Right-of-use assets

The Company is a party to lease contracts for:

–Land

–Plants and equipment for the production of industrial gases and other production materials.

–Transportation and maintenance equipment.

–Warehouses and office spaces.

These leases are recognized, measured and presented in accordance to IFRS 16 “Leases”, following the guidelines described below.

Accounting by the lessee

The Company recognizes a right-of-use asset and a lease liability at the commencement date of each lease contract that grants the right to control the use of an identified asset during a period of time. The commencement date is the date in which the lessor makes an underlying asset available for use by the lessee.

The Company applied exemptions for leases with a duration lower than 12 months, with a value lower than thirty thousand dollars and/or with clauses related to variable payments. These leases have been considered as short-term leases and, accordingly, no right-of-use asset or lease liability have been recognized.

At initial recognition, the right-of-use asset is measured considering:

– The value of the initial measurement of the lease liability;

– Any lease payments made at or before the commencement date, less any lease incentives; and

– Any initial direct costs incurred by the lessee.

After initial recognition, the right-of-use assets are measured at cost, less any accumulated depreciation and/or impairment losses, and adjusted for any re-measurement of the lease liability.

Depreciation of the right-of-use asset is calculated using the straight-line method over the estimated duration of the lease contract, as follows:

Buildings and facilities        1-28 years

Machinery            1-11 years

If the lease transfers ownership of the underlying asset to the Company by the end of the lease term, or if the cost of the right-of-use asset reflects that the Company will exercise a purchase option, the Company depreciates the right-of-use asset from the commencement date to the end of the useful life of the underlying asset. Otherwise, the Company depreciates the right-of-use asset from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.

Accounting by the lessor

When the Company is acting as a lessor, each of its leases is classified as either operating or finance lease:

– Leases where a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases.

– Leases where all substantial risks and rewards of ownership are transferred by the lessor to the lessee are classified as finance leases.

3.    ACCOUNTING POLICIES (continued)

(e)Intangible assets

(1)    Information system projects

Generally, costs associated with developing or maintaining computer software programs are recognized as an expense as incurred. However, costs directly related to the acquisition and implementation of information systems are recognized as intangible assets if they have a probable economic benefit exceeding the cost beyond one year and comply with the recognition criteria of IAS 38.

Information system projects recognized as assets are amortized using the straight-line method over their useful lives, not exceeding a period of 3 years. Amortization charges are included in cost of sales, selling, general and administrative expenses.

(2)    Mining assets

Mining assets include:

(a)Mining licenses acquired;

(b)Capitalized exploration and evaluation costs, reclassified from exploration and evaluation costs (see note 3 (e) 3); and

(c)Capitalized developmental stripping costs (see note 3 (u)).

Mining licenses were recognized as separate intangible assets upon the acquisition of the investment in Mexico and comprise the right to exploit the mines and are recognized at its fair value at acquisition date less accumulated amortization.

These mining concessions were granted for a 50-year period; following the expiration of the initial concession term, the concessions are renewable for an additional 50-year term in accordance with, and subject to the procedures set forth in, applicable Mexican mining law.

Amortization charge is calculated by using the unit-of-production method, on the basis of actual mineral extracted in each period compared to the estimated mineral reserves, and is included in cost of sales. Any change in the estimation of reserves is accounted for prospectively. The resulting amortization rate for the years ended December 31, 2021, 2020 and 2019, is approximately 7%, 4% and 5% per year, respectively.

3.    ACCOUNTING POLICIES (continued)

(3)Exploration and evaluation costs

Exploration and evaluation activities involve the search for iron ore resources, the determination of technical feasibility and the assessment of commercial viability of an identified resource.

Exploration and evaluation costs are measured at cost. Costs directly associated with exploration and evaluation activities are capitalized as intangible assets until the determination of reserves is evaluated. The costs associated to the acquisition of machinery and equipment are recognized as property, plant and equipment. If it is determined that commercial discovery has been achieved, costs incurred are reclassified into Mining assets and amortization starts once production begins.

Exploration costs are tested for impairment annually or whenever there are indicators that impairment exists. Indicators of impairment include, but are not limited to:

–Rights to explore in an area have expired or will expire in the near future without renewal;

–No further exploration and evaluation is planned or budgeted;

–A decision to discontinue exploration and evaluation in an area because of the absence of commercial reserves; and

–Sufficient data exists to indicate that the book value will not be fully recovered from future development and production.

When analyzing the existence of impairment indicators, the exploration and evaluation areas from the mining units will be evaluated.

(4)    Goodwill

Goodwill represents the excess of the acquisition cost over the fair value of Ternium's participation in acquired companies' net assets at the acquisition date. Under IFRS 3, goodwill is considered to have an indefinite life and not amortized, but is subject to annual impairment testing.

Goodwill is allocated to Cash-generating units ("CGU") for the purpose of impairment testing. The allocation is made to those cash-generating units expected to benefit from the business combination which generated the goodwill being tested. The impairment losses on goodwill cannot be reversed.

As of December 31, 2021 and 2020, the carrying amount of goodwill allocated to the Mexico CGU was $662.3 million, of which $619.8 million corresponds to steel operations and $42.5 million to mining operations.

(5)    Research and development

Research expenditures are recognized as expenses as incurred. Development costs are recorded as cost of sales in the income statement as incurred because they do not fulfill the criteria for capitalization. Research and development expenditures for the years ended December 31, 2021, 2020 and 2019 totaled $9.8 million, $8.3 million and $10.0 million, respectively.

3.    ACCOUNTING POLICIES (continued)

(6)    Customer relationships acquired in a business combination

In accordance with IFRS 3 and IAS 38, Ternium has recognized the value of customer relationships in connection with the acquisition of Ternium Staal B.V. as of September 7, 2017. The value of the slab commitment agreement by which Ternium Investments S.à r.l. was entitled to invoice, under certain conditions, the price difference between slabs and hot rolled coils has been amortized using the units of slabs sold method. As of December 31, 2021, the asset related to this slab commitment agreement was fully amortized.

(7)    Trademarks acquired in a business combination

Trademarks are amortized using the straight-line method over a useful life of between 5 to 10 years.

(f)    Impairment

Assets that have an indefinite useful life (including goodwill) are not subject to amortization and are tested annually for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets that are subject to amortization and investments in affiliates are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less cost to sell and the value in use.

To carry out these tests, assets are grouped at the lowest levels for which there are separately identifiable cash flows (each, a CGU). When evaluating long-lived assets for potential impairment, the Company estimates the recoverable amount based on the value in use of the corresponding CGU. The value in use of each CGU is determined on the basis of the present value of net future cash flows which will be generated by the assets tested.

Determining the present value of future cash flows involves highly sensitive estimates and assumptions specific to the nature of each CGU's activities, including estimates and assumptions relating to amount and timing of projected future cash flows, expected changes in market prices, expected changes in the demand of Ternium products and services, selected discount rate and selected tax rate.

Ternium uses, for the steel segment impairment tests, cash flow projections for the next five years based on past performance and expectations of market development; thereafter, it uses a perpetuity rate. In the case of CGU Mexico, cash flow projections are prepared until the mines are fully depleted and are based on past performance and expectations of market development; then a perpetuity rate starts. The growth rate used for the perpetuity rate is of 2.3%. Application of the discounted cash flow (DCF) method to determine the value in use of a CGU begins with a forecast of all expected future net cash flows. Variables considered in forecasts include the gross domestic product (GDP) growth rates of the country under study and their correlation with steel demand, level of steel prices and estimated raw material costs as observed in industry reports.

3.    ACCOUNTING POLICIES (continued)

Cash flows are discounted at rates that reflect specific country and currency risks associated with the cash flow projections. The discount rates used are based on the weighted average cost of capital (WACC), which is considered to be a good indicator of cost of capital. As of December 31, 2021 the discount rate used to test goodwill allocated to the Steel and Mining Mexico CGU for impairment was 9.93% (as of December 31, 2020, 8.87%).

As a result of the above factors, actual cash flows and values could vary significantly from the forecasted future cash flows and related values derived using discounting techniques. Based on the information currently available, however, Ternium believes that it is not reasonably possible that the variation would cause the carrying amount to exceed the recoverable amount of the CGUs.

Considering the economic situation in Argentina, the increase in the inflation rates, the devaluation of the Argentine peso and a weaker industrial environment as of June 30, 2020, the Company decided to assess the recoverability of its investments in Argentina, resulting in no impairment charges to be recognized. As of June 30, 2020, the discount rate used to test the investment in Argentine subsidiaries for impairment was 14.3%. Also, considering the economic situation in Brazil as of June 30, 2020, the Company decided to assess the recoverability of its investments in Brazil, resulting in no impairment charges to be recognized. As of June 30, 2020, the discount rate used to test the investment in the Brazilian subsidiary for impairment was 10.3%. As of December 31, 2021 and 2020, no new impairment triggers were detected in these CGUs and, consequently, no impairment tests were prepared.

In connection with investments in non-consolidated companies and considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company decided to assess the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. As of December 31, 2021, the discount rate used to test the investment in Usiminas for impairment was 11.95%.

During the years 2021, 2020 and 2019, no impairment provisions were recorded in connection with assets that have an indefinite useful life (including goodwill).

(g)     Other investments

Other investments consist primarily of investments in financial debt instruments and equity investments where the Company holds a minor equity interest and does not exert significant influence.

All purchases and sales of investments are recognized on the settlement date, which is not significantly different from the trade date, which is the date that Ternium commits to purchase or sell the investment.

Income from financial instruments at fair value through profit or loss is recognized in Other financial income (expenses), net in the consolidated income statement. The fair value of quoted investments is based on current bid prices. If the market for a financial investment is not active or the securities are not listed, the Company estimates the fair value by using standard valuation techniques. Dividends from investments in equity instruments are recognized in the income statement when the Company's right to receive payments is established.

Certain fixed income financial instruments purchased by the Company have been categorized as at fair value through other comprehensive income. The results of these financial investments are recognized in Finance Income in the Consolidated Income Statement using the effective interest method. Unrealized gains and losses other than impairment and foreign exchange results are recognized in Other comprehensive income. On maturity or disposal, net gain and losses previously deferred in Other comprehensive income are recognized in Finance Income in the Consolidated Income Statement.

3.    ACCOUNTING POLICIES (continued)

(h)Inventories

Inventories are stated at the lower of cost (calculated using the first-in-first-out "FIFO" method) or net realizable value. The cost of finished goods and goods in process comprises raw materials, direct labor, depreciation, other direct costs and related production overhead costs. It excludes borrowing costs. Goods acquired in transit at year end are valued at supplier's invoice cost.

The cost of iron ore produced in our mines comprises all direct costs necessary to extract and convert stockpiled inventories into raw materials, including production stripping costs, depreciation of fixed assets related to the mining activity and amortization of mining assets for those mines under production.

The Company assesses the recoverability of its inventories considering their selling prices, if the inventories are damaged, or if they have become wholly or partially obsolete (see note 3 (bb) (4)).

(i)Trade receivables and other receivables

Trade and other receivables are recognized initially at fair value, generally the original invoice amount. The Company applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables are grouped based on shared credit risk characteristics and the days past due. The Company keeps an allowance for trade receivables, recorded in an asset account to offset the trade receivables in an amount estimated sufficient to cover the losses resulting from the impossibility for the debtors to cancel the amounts owed. This allowance for trade receivables is recorded with a charge to selling expenses.

(j)    Cash and cash equivalents

Cash and cash equivalents and highly liquid short-term securities are carried at fair market value or at a historical cost which approximates fair market value.

For purposes of the cash flow statement, cash and cash equivalents comprise cash, bank current accounts and short-term highly liquid investments (original maturity of three months or less at date of acquisition) and overdrafts.

In the consolidated statement of financial position, bank overdrafts are included in borrowings within current liabilities.

(k)     Assets (disposal groups) classified as held for sale

Assets (disposal groups) are classified as assets held for sale, complying with the recognition criteria of IFRS 5, and stated at the lower of carrying amount and fair value less cost to sell if their carrying amount is recovered principally through a sale transaction rather than through continuing use.

The carrying value of assets classified as held for sale, at December 31, 2021 and 2020 totals $1.9 million and $5.0 million, respectively, which corresponds principally to land and other real estate items. Sale is expected to be completed within a one-year period.

3.    ACCOUNTING POLICIES (continued)

(l)     Borrowings

Borrowings are recognized initially for an amount equal to the net proceeds received. In subsequent periods, borrowings are stated at amortized cost following the effective interest method.

(m)    Lease liabilities

The lease liability is initially measured at the present value of the lease payments that are not paid at such date, including the following concepts:

– Fixed payments, less any lease incentives receivable;

– Variable lease payments that depend on an index or rate, initially measured using the index or rate as of the commencement date;

– Amounts expected to be payable by the lessee under residual value guarantees;

– The exercise price of a purchase option if the lessee is reasonably certain to exercise that option; and

– Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

Variable lease liabilities with payments dependent on external factors, such as minimum volumes sold or used, are not included in the initial measurement of the lease liabilities and such payments are recognized directly in profit and loss.

Lease payments are discounted using incremental borrowing rates for the location and currency of each lease contract or, if available, the rate implicit in the lease contract.

The finance cost is charged to profit or loss over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

The lease term determined by the Company comprises:

– Non-cancelable period of lease contracts;

– Periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and

– Periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option.

After the commencement date, the Company measures the lease liability by:

– Increasing the carrying amount to reflect interest on the lease liability;

– Reducing the carrying amount to reflect lease payments made; and

– Re-measuring the carrying amount to reflect any reassessment or lease modifications.

(n)    Income taxes - current and deferred

The current income tax charge is calculated on the basis of the tax laws in force in the countries in which Ternium and its subsidiaries operate. Management evaluates positions taken in tax returns with respect to situations in which applicable tax regulation could be subject to interpretation. A liability is recorded for tax benefits that were taken in the applicable tax return but have not been recognized for financial reporting.

3.    ACCOUNTING POLICIES (continued)

Deferred income taxes are calculated using the liability method on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting, nor taxable profit or loss. The principal temporary differences arise on fixed assets, intangible assets, inventories valuation and provisions for pensions. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantially enacted at year end. Under IFRS, deferred income tax assets (liabilities) are classified as non-current assets (liabilities).

Deferred tax assets are recognized to the extent it is probable that future taxable income will be available to offset temporary differences.

Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associated companies, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.

Deferred tax assets and liabilities are re-estimated if tax rates change. These amounts are charged or credited to the consolidated income statement or to the item “Other comprehensive income for the year” in the consolidated statement of comprehensive income, depending on the account to which the original amount was charged or credited.

(o)    Employee liabilities

(1)    Post-employment obligations

The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually (at year end) by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. In countries where there is no deep market in such bonds, the market rates on government bonds are used.

Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise. Past-service costs are recognized immediately in income.

For defined benefit plans, net defined benefit liability/asset is calculated based on the surplus or deficit derived by the difference between the defined benefit obligations less plan assets.

3.    ACCOUNTING POLICIES (continued)

For defined contribution plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

Mexico

Ternium Mexico has defined benefit and defined contribution plans.

The valuation of the liabilities for the defined benefit employee retirement plans (pensions and seniority premiums) covers all employees and is based primarily on their years of service, their present age and their remuneration at the date of retirement. The cost of the employee retirement plans (pension, health-care expenses and seniority premiums) is recognized as an expense in the year in which services are rendered in accordance with actuarial studies made by independent actuaries. The formal retirement plans are congruent with and complementary to the retirement benefits established by the Mexican Institute of Social Security. Additionally, the Company has established a plan to cover health-care expenses of retired employees. The Company has established a commitment for the payment of pensions and seniority premiums, as well as for health-care expenses.

The defined contribution plans provide a benefit equivalent to the capital accumulated with the company's contributions, which are provided as a match of employees' contributions to the plan. The plan provides vested rights according to the years of service and the cause of retirement.

Argentina

Ternium Argentina implemented an unfunded defined benefit employee retirement plan for certain senior officers. The plan is designed to provide certain benefits to those officers (additional to those contemplated under applicable Argentine labor laws) in case of termination of the employment relationship due to certain specified events, including retirement. This unfunded plan provides defined benefits based on years of service and final average salary.

(2)Termination benefits

Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits when it is demonstrably committed to either: (i) terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal or (ii) providing termination benefits as a result of an offer made to encourage voluntary redundancy.

(3)    Other compensation obligations

Employee entitlements to annual leave and long-service leave are accrued as earned.

3.    ACCOUNTING POLICIES (continued)

During 2007, Ternium launched an incentive retention program (the "Program") applicable to certain senior officers and employees of the Company, who will be granted a number of Units throughout the duration of the Program. The value of each of these Units is based on Ternium's shareholders' equity (excluding non-controlling interest). Also, the beneficiaries of the Program are entitled to receive cash amounts based on (i) the amount of dividend payments made by Ternium to its shareholders, and (ii) the number of Units held by each beneficiary to the Program. Units vest ratably over a period of four years and will be redeemed by the Company ten years after grant date, with the option of an early redemption at seven years after grant date. From 2018 units were vest ratably over the same period and will be mandatorily redeemed by the Company seven years after grant date. As the cash payment of the benefit is tied to the book value of the shares, and not to their market value, Ternium valued this long-term incentive program as a long term benefit plan as classified in IAS 19.

As of December 31, 2021 and 2020, the outstanding liability corresponding to the Program amounts to $67.7 million and $43.4 million, respectively. The total value of the units granted to date under the program, considering the number of units and the book value per share as of December 31, 2021 and 2020, is $72.1 million and $43.3 million, respectively.

Under Mexican law, Ternium's subsidiaries are required to pay their employees an annual benefit which is determined as a percentage of taxable profit for the year.

(4)    Social security contributions

Social security laws in force in the countries in which the Company operates provide for pension benefits to be paid to retired employees from government pension plans and/or private fund managed plans to which employees may elect to contribute. As stipulated by the respective laws, Ternium Argentina and Ternium Mexico make monthly contributions calculated based on each employee's salary to fund such plans. The related amounts are expensed as incurred. No additional liabilities exist once the contributions are paid.

(p)    Provisions

Ternium has certain contingencies with respect to existing or potential claims, lawsuits and other proceedings. Unless otherwise specified, Ternium accrues a provision for a present legal or constructive obligation as a result of a past event, when it is probable that future cost could be incurred and that cost can be reasonably estimated. Generally, accruals are based on developments to date, Ternium's estimates of the outcomes of these matters and the advice of Ternium's legal advisors.

(q)    Trade payables

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.

3.    ACCOUNTING POLICIES (continued)

(r)    Revenue recognition and other income

Revenue is recognized at a point of time from sales to direct customers upon the satisfaction of performance obligations, which occurs when control of the goods transfers to the customer and the customer obtains the benefits from the goods, the potential cash flows and the transaction price can be measured reliably, and it is probable that the Company will collect the consideration in connection with the exchange of the goods. The control over the goods is obtained by the customer depending on when the goods are made available to the shipper or the customer takes possession of the goods, depending on the delivery terms. The Company considers that it has completed its performance obligations when the goods are delivered to its customers or to a shipper who will transport the goods to its customers. The revenue recognized by the Company is measured at the transaction price of the consideration received or receivable to which the Company is entitled to, reduced by estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized and after eliminating sales within the group.

Interest income is recognized on an effective yield basis.

(s)    Borrowing Costs

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

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

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

The amount of borrowing costs that Ternium capitalized during a period will not exceed the amount of borrowing costs incurred during that period. At December 31, 2021, 2020 and 2019, the capitalized borrowing costs were of $6.3 million, $13.1 million and $16.1 million, respectively.

(t)    Cost of sales, selling, general and administrative expenses

Cost of sales and expenses are recognized in the income statement on the accrual basis of accounting.

Commissions, freight and other selling expenses, including shipping and handling costs, are recorded in Selling, general and administrative expenses in the Consolidated Income Statement.

(u)    Stripping costs

Stripping costs are the costs associated with the removal of overburden and other waste materials and can be incurred before the mining production commences (“development stripping”) or during the production stage (“production stripping”).

3.    ACCOUNTING POLICIES (continued)

Development stripping costs that contribute to the future economic benefits of mining operations are capitalized as intangible assets (Mining assets). Production stripping costs which are part of on-going activities are included in the cost of the inventory produced (that is extracted) at each mine during the period in which they are incurred.

Capitalization of development stripping costs finishes when the commercial production of the mine commences. At that time, all development stripping costs are presented within Mining assets and depreciated on a unit-of-production basis. It is considered that commercial production begins when the production stage of mining operations begins and continues throughout the life of a mine.

(v)    Mining development costs

Mining development costs are the costs associated to the activities related to the establishment of access to the mineral reserve and other preparations for commercial production. These activities often continue during production.

Development expenditures are capitalized and classified as Work in progress. On completion of development, all assets included in Work in progress are individually reclassified to the appropriate category of property, plant and equipment and depreciated accordingly.

(w)    Asset retirement obligations

Ternium records asset retirement obligations (“ARO”) initially at the fair value of the legal or constructive obligation in the period in which it is incurred and capitalizes the ARO by increasing the carrying amount of property, plant and equipment. The fair value of the obligation is determined as the discounted value of the expected future cash flows and is included in Provisions. The liability is accreted to its present value through net financing cost and the capitalized cost is depreciated based in the unit of production method.

(x)    Earnings per share

Earnings per share are calculated by dividing the net income attributable to shareholders by the daily weighted average number of ordinary shares issued during the year, excluding the average number of shares of the parent Company held by the Group. There are no dilutive securities for the periods presented.

(y)    Derivative financial instruments and hedging activities

Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly interest rate swaps, collars, currency forward contracts on highly probable forecast transactions and commodities contracts). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in OCI. Amounts accumulated in OCI are recognized in the income statement in the same period as any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected in the statement of financial position.

3.    ACCOUNTING POLICIES (continued)

For transactions designated and qualifying for hedge accounting, Ternium documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. At December 31, 2021 and 2020, the effective portion of designated cash flow hedges (net of taxes) amounted to $(0.04) million and $(0.23) million, respectively, and were included under "changes in the fair value of derivatives classified as cash flow hedges" line item in the statement of comprehensive income (see Note 26 (a)).

More information about accounting for derivative financial instruments and hedging activities is included in Note 28 "Financial risk management".

(z)    Treasury shares

Acquisitions of treasury shares are recorded at acquisition cost, deducted from equity until disposal. The gains and losses on disposal of treasury shares are recognized under "Reserves" in the consolidated statement of financial position.

(aa)    Cash flow

The consolidated statements of cash flows have been prepared using the indirect method and contain the use of the following expressions and their respective meanings:

a)    Operating activities: activities that constitute ordinary Group revenues, as well as other activities that cannot be qualified as investing or financing.

b)    Investing activities: acquisition, sale or disposal by other means of assets in the long-term and other investments not included in cash and cash equivalents.

c)    Financing activities: activities that generate changes in the size and composition of net equity and liabilities that do not form part of operating activities.

(bb)    Critical Accounting Estimates

The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Management makes estimates and assumptions concerning the future. Actual results may differ significantly from these estimates under different assumptions or conditions.

The principal estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

(1) Goodwill impairment test

Assessment of the recoverability of the carrying value of goodwill requires significant judgment. Management evaluates goodwill allocated to the operating units for impairment on an annual basis or whenever there is an impairment indicator.

3.    ACCOUNTING POLICIES (continued)

Goodwill is tested at the level of the CGUs. Impairment testing of the CGUs is carried out and the value in use determined in accordance with the accounting policy stated in Note 3(f). The discount rates used for these tests are based on Ternium's weighted average cost of capital adjusted for specific country and currency risks associated with the cash flow projections. The discount rate used at December 31, 2021 was 9.93% and no impairment charge resulted from the impairment test performed. See notes 3(f) and 3(e)(4).

(2)Income taxes

Management calculates current and deferred income taxes according to the tax laws applicable to each subsidiary in the countries in which such subsidiaries operate. However, due to uncertain tax positions, certain adjustments necessary to determine the income tax provision are finalized only after the balance sheet is issued. In cases in which the final tax outcome is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Also, when assessing the recoverability of tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies.

(3)    Loss contingencies

Ternium is subject to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business, including customer claims in which a third party is seeking reimbursement or indemnity. The Company's liability with respect to such claims, uncertain tax positions, lawsuits and other legal proceedings cannot be estimated with certainty. Periodically, management reviews the status of each significant matter and assesses potential financial exposure. If the potential loss from the claim or proceeding is considered probable and the amount can be reasonably estimated, a liability is recorded. Management estimates the amount of such liability based on the information available and the assumptions and methods it has concluded are appropriate, in accordance with the provisions of IFRS. Accruals for such contingencies reflect a reasonable estimate of the losses to be incurred based on information available, including the relevant litigation or settlement strategy, as of the date of preparation of these financial statements. As additional information becomes available, management will reassess its evaluation of the pending claims, lawsuits and other proceedings and revise its estimates. The loss contingencies provision amounts to $83.3 million and $80.6 million as of December 31, 2021 and 2020, respectively,.

(4)Allowance for obsolescence of supplies and spare parts and slow-moving inventory

Management assesses the recoverability of its inventories considering their selling prices or whether they are damaged or have become wholly or partly obsolete.

Net realizable value is the estimated selling price in the ordinary course of business, less the costs of completion and selling expenses.

The Company establishes an allowance for obsolete or slow-moving inventory in connection with finished goods and goods in process. The allowance for slow-moving inventory is recognized for finished goods and goods in process based on management's analysis of their aging. In connection with supplies and spare parts, the calculation is based on management's analysis of their aging, the capacity of such materials to be used based on their levels of preservation and maintenance, and their potential obsolescence due to technological change.

3.    ACCOUNTING POLICIES (continued)

As of December 31, 2021 and 2020, the Company recorded no allowance for net realizable value and $61.5 million and $58.6 million, respectively, as allowance for obsolescence.

(5)Useful lives and Impairment of Property, Plant and Equipment and Other Long-lived Assets

In determining useful lives, management considered, among others, the following factors: age, operating condition and level of usage and maintenance. Management conducted visual inspections for the purpose of (i) determining whether the current conditions of such assets are consistent with normal conditions of assets of similar age; (ii) confirming that the operating conditions and levels of usage of such assets are adequate and consistent with their design; (iii) establishing obsolescence levels and (iv) estimating life expectancy, all of which were used in determining useful lives. Management believes, however, that it is possible that the periods of economic utilization of property, plant and equipment may be different than the useful lives so determined. Furthermore, management believes that this accounting policy involves a critical accounting estimate because it is subject to change from period to period as a result of variations in economic conditions and business performance.

When assessing whether an impairment indicator may exist, the Company evaluates both internal and external sources of information, such as the following:

–whether significant changes with an adverse effect on the entity have taken place during the period, or will take place in the near future, in the technological, market, economic or legal environment in which the entity operates or in the market to which an asset is dedicated;

–whether market interest rates or other market rates of return on investments have increased during the period, and those increases are likely to affect the discount rate used in calculating an asset's value in use and decrease the asset's recoverable amount materially;

–whether the carrying amount of the net assets of the entity is more than its market capitalization;

–whether evidence is available of obsolescence or physical damage of an asset.

–whether significant changes with an adverse effect on the entity have taken place during the period, or are expected to take place in the near future, in the extent to which, or manner in which, an asset is used or is expected to be used. These changes include the asset becoming idle, plans to discontinue or restructure the operation to which an asset belongs, plans to dispose of an asset before the previously expected date, and reassessing the useful life of an asset as finite rather than indefinite; and

–whether evidence is available from internal reporting that indicates that the economic performance of an asset is, or will be, worse than expected.

Considering the economic situation in Argentina as of December 31, 2019, and as of June 30, 2020, the Company tested the recoverability of its investment in Ternium Argentina as of such dates, resulting in no impairment charges to be recognized. As of December 31, 2021 and 2020, no new impairment triggers were detected and, consequently, no impairment test was prepared.

The Company also tested the recoverability of its investments in the rest of the subsidiaries as of June 30, 2020, due to the pandemic, resulting in no impairment charges to be recognized. Considering that no new impairment indicators were identified in the rest of subsidiaries as of December 31, 2021 and 2020, the Company additionally tested the value of the goodwill for impairment, resulting in no impairment charges to be recognized.

In connection with investments in non-consolidated companies and considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company decided to assess the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. As of December 31, 2021, the discount rate used to test the investment in Usiminas for impairment was 11.95%.

3.    ACCOUNTING POLICIES (continued)

(6)    Mining reserve estimates

Reserves are estimates of the amount of product that can be economically and legally extracted from the Company’s mining concessions. In order to estimate reserves, a range of geological, technical and economic factors is required to be considered. Estimating the quantity and/or grade of reserves requires complex and difficult geological judgments to interpret the data. Because the economic assumptions used to estimate reserves change from period to period, and because additional geological data is generated during the course of operations, estimates of reserves may change from period to period.

Changes in reported reserves may affect the Company’s financial results and financial position, including the following:

–Asset carrying amounts may be affected due to changes in estimated future cash flows.

–Depreciation and amortization charges may change where such charges are determined by the units of production basis, or where the useful economic lives of assets change.

–Stripping costs recognized in Mining assets or charged to results may change due to changes in stripping ratios or the units of production basis of depreciation.

–Asset retirement obligations may change where changes in estimated reserves affect expectations about the timing or cost of these activities.

(7)    Post-employment obligation estimates

The Company estimates at each year-end the provision necessary to meet its post-employment obligations in accordance with the advice from independent actuaries. The calculation of post-employment and other employee obligations requires the application of various assumptions. The main assumptions for post-employment and other employee obligations include discount rates, compensation growth rates, pension growth rates and life expectancy.  Changes in the assumptions could give rise to adjustments in the results and liabilities recorded and might have an impact on the post-employment and other employee obligations recognized in the future.

(8)    Valuation of lease liabilities and right-of-use assets

The application of IFRS 16 requires the Company to make judgments that affect the recognition and valuation of the lease liabilities and the right-of-use assets, including the determination of the contracts within the scope of the Standard, the contract term and the interest rate used for the discount of future cash flows.

The lease term determined by the Company generally comprises non-cancellable period of leases contracts, periods covered by an option to extend the lease if the Company is reasonably certain to exercise that option and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option. The same term is applied as economic useful life of right-of-use assets.

3.    ACCOUNTING POLICIES (continued)

The present value of the lease payments is determined using the discount rate representing a risk-free interest rate, adjusted by a spread related to the credit quality of the Company in each location and currency rate in connection with each lease contract.

(9) Change in the functional currency of argentine subsidiaries

The determination of the functional currency requires management to make significant judgments. Ternium Argentina has performed a review of its functional currency and concluded that the currency that most faithfully represents the economics effects of the entity is the U.S. dollar and therefore its functional currency has changed from the local currency to the U.S. dollar. This change was prospective from January 1, 2020, and did not affect the balances at December 31, 2019, nor results or cash flows for the year then ended.

It was based on the following considerations:

–In the last two years, the exchange rate of the Argentine peso has been severely affected by devaluations against the U.S. dollar and Argentina continues to be a highly inflationary economy. These events had very limited impact on sale's price in U.S. dollar;

–In this context, there is also a greater proportion of total production cost in U.S. dollar;

–Furthermore, new global trade restrictions, affecting the international trade of steel along with limited restrictions of imports in Argentina, have led to a greater correlation of local prices to global prices.

–Factors to determine the functional currency were always mixed. However, currently most of revenue and costs of production are negotiated and priced in U.S. dollar.

The change in functional currency of Ternium Argentina significantly reduced the volatility of the Company’s earnings that was due to foreign exchange movements and the application of IAS 29 - Financial Reporting in Hyperinflationary Economies.

(cc)    Application of IAS 29 in financial reporting of Argentine subsidiaries and associates

For the years ended December 31, 2019 and 2018, the Company applied IAS 29 “Financial Reporting in Hyperinflationary Economies”, which requires that the financial statements of entities whose functional currency is that of a hyperinflationary economy to be adjusted for the effects of changes in a suitable general price index and to be expressed in terms of the current unit of measurement at the closing date of the reporting period. Accordingly, the inflation produced from the date of acquisition or from the revaluation date, as applicable, must be computed in the non-monetary items.

In order to conclude on whether an economy is categorized as hyperinflationary under the terms of IAS 29, the Standard details a series of factors to be considered, including the existence of a cumulative inflation rate in three years that approximates or exceeds 100%.

Considering that the significant increase in inflation during 2018, which exceeded the 100% three-year cumulative inflation rate, and that the rest of the indicators did not contradict the conclusion that Argentina should be considered a hyperinflationary economy for accounting purposes, the Company considered that there was sufficient evidence to conclude that Argentina was a hyperinflationary economy under the terms of IAS 29 as from July 1, 2018, and, accordingly, applied IAS 29 as from that date in the financial reporting of its subsidiaries and associates with the Argentine peso as functional currency.

3.    ACCOUNTING POLICIES (continued)

According to this principle, the financial statements of an entity that reports in the currency of a hyperinflationary economy should be stated in terms of the measuring unit current on the date of the financial statements. All statement of financial position amounts that are not stated in terms of the measuring unit current on the date of the financial statements must be restated by applying a general price index. All income statement components must be stated in terms of the measuring unit current on the date of the financial statements, applying the change in the general price index that occurred since the date when revenues and expenses were originally recognized in the financial statements.

The inflation adjustment on the initial balances was calculated by means of conversion factor derived from the Argentine price indexes published by the National Institute of Statistics (“INDEC”). The price index for the year periods ended December 31, 2019 and 2018, were 1.54 and 1.48, respectively.

The main procedures for the above-mentioned adjustment are as follows:

–Monetary assets and liabilities which are carried at amounts current at the balance sheet date are not restated because they are already expressed in terms of the monetary unit current at the balance sheet date.

–Non-monetary assets and liabilities which are not carried at amounts current at the balance sheet date, and components of shareholders' equity are adjusted by applying the relevant conversion factors.

–All items in the income statement are restated by applying the relevant conversion factors.

–The effect of inflation on the Company’s net monetary position is included in the income statement, in Other financial income (expenses), net, under the caption “Inflation adjustment results”.

–The ongoing application of the re-translation of comparative amounts to closing exchanges rates under IAS 21 and the hyperinflation adjustments required by IAS 29 will lead to a difference in addition to the difference arising on the adoption of hyperinflation accounting.

The comparative figures in these consolidated financial statements presented in a stable currency are not adjusted for subsequent changes in the price level or exchange rates. This resulted in an initial difference, arising on the adoption of hyperinflation accounting, between the closing equity of the previous year and the opening equity of the current year. The Company recognized this initial difference directly in equity.

(dd) Climate Change

Ternium is committed to the UN Global Compact Initiative, its sustainable development goals, and the world's efforts to address Climate Change.

The Company is determined to find ways to reduce the carbon footprint of its operations and the steel value chain. In February 2021, Ternium announced a medium-term target to reduce its carbon dioxide emissions intensity rate by 20% in 2030, compared to its 2018 base rate of 1.7 tons of carbon dioxide per ton of steel. The Company’s strategy to achieve this 2030 reduction target consists of a multi-faceted approach that includes increasing the use of renewable energy and the development of energy efficiency strategies, increasing the participation of scrap in the metallic mix, improving the carbon capture capacity at its DRI facilities, replacing coking coal with charcoal and prioritizing lower specific-emission steelmaking technologies.

The Company intends to continue analyzing and developing measures to decarbonize its operations over the longer term. This endeavor will require significant long-term investments, conditioned by technology innovation, cooperation within the value chain, government regulations, and capital availability for decarbonization projects. Factors like access to abundant and affordable clean energy, appropriate energy infrastructure, local and global regulation that guarantee fair trade and carbon capture storage, access to sustainable finance for low emissions steel-making technologies, and changes in consumer behavior will be key in the development of solutions and the outcomes in the next decades.

Given that Ternium’s climate-change-related decarbonization plans span over many years and are subject to significant uncertainty as described above, they have not been included as part of the assumptions used to calculate future cash flows of the recoverable amount of the company’s CGUs. Estimates and assumptions related to the impairment test over long-lived assets and goodwill, useful lives of assets, capital and research and development expenditures, inventory valuation, recovery of deferred tax assets and provisions, and contingent liabilities are based on available information and government regulations in place as of December 31, 2021, as well as on the company’s current short-term investment plans.

Disclosure of entity's operating segments [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

REPORTABLE OPERATING SEGMENTS

The Company is organized in two reportable segments: Steel and Mining.

The Steel segment includes the sales of steel products, which comprises slabs, hot rolled coils and sheets, cold rolled coils and sheets, tin plate, welded pipes, hot dipped galvanized and electro-galvanized sheets, pre-painted sheets, billets (steel in its basic, semi-finished state), wire rod and bars and other tailor-made products to serve its customers’ requirements.

It also includes the sales of energy.

The Steel segment comprises four operating segments: Mexico, Southern Region, Brazil and Other markets. These four segments have been aggregated considering the economic characteristics and financial effects of each business activity in which the entity engages; the related economic environment in which it operates; the type or class of customer for the products; the nature of the products; and the production processes. The Mexico operating segment comprises the Company’s businesses in Mexico. The Southern region operating segment manages the businesses in Argentina, Paraguay, Chile, Bolivia and Uruguay. The Brazil operating segment includes the business generated in Brazil. The Other markets operating segment includes businesses mainly in United States, Colombia, Guatemala and Germany.

The Mining segment includes the sales of mining products, mainly iron ore and pellets, and comprises the mining activities of Las Encinas, an iron ore mining company in which Ternium holds a 100% equity interest and the 50% of the operations and results performed by Peña Colorada, another iron ore mining company in which Ternium maintains that same percentage over its equity interest. Both mining operations are located in Mexico. For Peña Colorada, the Company recognizes its assets, liabilities, revenue and expenses in relation to its interest in the joint operation.

Ternium’s Chief Operating Decision Maker (CEO) holds monthly meetings with senior management, in which operating and financial performance information is reviewed, including financial information that differs from IFRS principally as follows:

–The use of direct cost methodology to calculate the inventories, while under IFRS is at full cost, including absorption of production overheads and depreciation.

–The use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at historical cost (with the FIFO method).

–Other timing and non-significant differences.

Most information on segment assets is not disclosed as it is not reviewed by the CEO.

For 2019, it includes mainly the application of the new tax law in Argentina that enables the tax inflation adjustment. The reduction of the tax rate in Argentina enacted in 2017 was modified in 2019, setting the corporate income tax rate to 30% for the year 2020 and to 25% from the year 2021 going forward.

(2) It includes the recovery of tax credits in Ternium Brasil Ltda.

Income tax expense for the years ended December 31, 2021, 2020 and 2019 differed from the amount computed by applying the statutory income tax rate in force in each country in which the company operates to pre-tax income as a result of the following:

Income tax expense	(1,397,139)	(291,488)	(196,519)

(1) Ternium applies the liability method to recognize deferred income tax on temporary differences between the tax bases of assets and their carrying amounts in the financial statements. By application of this method, Ternium recognizes gains and losses on deferred income tax due to the effect of the change in the value on the tax basis in subsidiaries, which have a functional currency different to their local currency, mainly Mexico and Argentina.

Tax rates used to perform the reconciliation between tax expense (income) and accounting profit are those in effect at each relevant date or period in each applicable jurisdiction.

DEFERRED INCOME TAX

Deferred income taxes are calculated in full on temporary differences under the liability method using the tax rate of the applicable country.

Changes in deferred income tax are as follows:

	As of December 31,
	2021	2020
At the beginning of the year	(187,782)	(239,740)

(a)Usinas Siderurgicas de Minas Gerais S.A. – USIMINAS

As of December 31, 2021, Ternium, through its subsidiaries, owns a total of 242.6 million ordinary shares and 8.5 million preferred shares, representing 20.4% of the issued and outstanding share capital of Usinas Siderurgicas de Minas Gerais S.A. – USIMINAS (“Usiminas”), the largest flat steel producer in Brazil for the energy, automotive and other industries.

Ternium, through its subsidiaries, together with Tenaris S.A.’s Brazilian subsidiary Confab Industrial S.A. (“TenarisConfab”), are part of Usiminas’ control group, comprising the so-called T/T Group. As at December 31, 2021, the Usiminas control group holds, in the aggregate, 483.6 million ordinary shares bound to the Usiminas shareholders’ agreement, representing approximately 68.6% of Usiminas’ voting capital. The Usiminas control group, which is bound by a long-term shareholders’ agreement that governs the rights and obligations of Usiminas’ control group members, is currently composed of three sub-groups: the T/T Group; the NSC Group, comprising Nippon Steel Corporation (“NSC”), Metal One Corporation and Mitsubishi Corporation; and Usiminas’ pension fund Previdência Usiminas. The T/T Group holds approximately 47.1% of the total shares held by the control group (39.5% corresponding to the Ternium entities and the other 7.6% corresponding to TenarisConfab); the NSC Group holds approximately 45.9% of the total shares held by the control group; and Previdência Usiminas holds the remaining 7%.

13.    INVESTMENTS IN NON-CONSOLIDATED COMPANIES (continued)

The corporate governance rules reflected in the Usiminas shareholders agreement provide, among other things, that Usiminas’ executive board will be composed of six members, including the chief executive officer and five vice-presidents, with Ternium and NSC nominating three members each. The right to nominate Usiminas’ chief executive officer alternates between Ternium and NSC at every 4-year interval, with the party that does not nominate the chief executive officer having the right to nominate the chairman of Usiminas’ board of directors for the same 4-year period. The Usiminas shareholders agreement also provides for an exit mechanism consisting of a buy-and-sell procedure—exercisable at any time after November 16, 2022 and applicable with respect to shares held by NSC and the T/T Group—, which would allow either Ternium or NSC to purchase all or a majority of the Usiminas shares held by the other shareholder.

As of December 31, 2021, the closing price of the Usiminas ordinary and preferred shares, as quoted on the BM&F Bovespa Stock Exchange, was BRL 14.51 (approximately $2.60; December 31, 2020: BRL15.69 - $3.02) per ordinary share and BRL15.16 (approximately $2.72; December 31, 2019: BRL14.61 - $2.81) per preferred share, respectively. Accordingly, as of December 31, 2021, Ternium’s ownership stake had a market value of approximately $653.9 million ($756.3 million as of December 31, 2020) and a carrying value of $681.7 million ($422.9 million as of December 31, 2020).

Considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company tested the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. Furthermore, the Company reviews periodically the recoverability of its investment in Usiminas. To determine the recoverable value, the Company estimates the value in use of the investment by calculating the present value of the expected cash flows or its fair value less costs of disposal.

As of December 31, 2021 and 2020, the value of the investment in Usiminas is comprised as follows:

	USIMINAS
Value of investment	As of December 31, 2021	As of December 31, 2020

At the end of the year	681,711	422,948

(1) It includes the adjustment of the values associated to the purchase price allocation.

Income tax expense for each of the years presented is as follows:

	Year ended December 31,

Income tax expense	(1,397,139)	(291,488)	(196,519)

(1) For 2021, it includes the modification of the tax rate in Argentina enacted in 2017 and modified in 2019 and 2021, setting the corporate income tax rate to 35% for the year 2021 going forward.

For 2019, it includes mainly the application of the new tax law in Argentina that enables the tax inflation adjustment. The reduction of the tax rate in Argentina enacted in 2017 was modified in 2019, setting the corporate income tax rate to 30% for the year 2020 and to 25% from the year 2021 going forward.

(2) It includes the recovery of tax credits in Ternium Brasil Ltda.

Income tax expense for the years ended December 31, 2021, 2020 and 2019 differed from the amount computed by applying the statutory income tax rate in force in each country in which the company operates to pre-tax income as a result of the following:

	Year ended December 31,
	2021	2020	2019
Income before income tax	5,764,330	1,159,359	826,564

Effect of changes in tax law	(9,117)	—	21,157
Income tax expense	(1,397,139)	(291,488)	(196,519)

(1) Ternium applies the liability method to recognize deferred income tax on temporary differences between the tax bases of assets and their carrying amounts in the financial statements. By application of this method, Ternium recognizes gains and losses on deferred income tax due to the effect of the change in the value on the tax basis in subsidiaries, which have a functional currency different to their local currency, mainly Mexico and Argentina.

Tax rates used to perform the reconciliation between tax expense (income) and accounting profit are those in effect at each relevant date or period in each applicable jurisdiction.

Deferred income taxes are calculated in full on temporary differences under the liability method using the tax rate of the applicable country.

	(1,889)	(6,358)

Derivative financial instruments breakdown is as follows:

(a) Interest rate contracts

Fluctuations in market interest rates create a degree of risk by affecting the amount of the Company’s interest payments and the value of its floating-rate debt. As of December 31, 2021, most of the Company’s long-term borrowings were at variable rates.

During 2012 and 2013, Tenigal entered into several forward starting interest rate swap agreements in order to fix the interest rate to be paid over an aggregate amount of $100 million, at an average rate of 1.92%. As of December 31, 2021, only $6.3 million remain outstanding. These agreements,which became effective during July 2014, will be due on July 2022 and have been accounted for as cash flow hedges. As of December 31, 2021, the after-tax cash flow hedge reserve related to these agreements amounted to $(0.04) million.

Changes in fair value of derivative instruments designated as cash flow hedges for each of the years presented are included below:

	Cash flow hedges
	Gross amount	Income tax	Total
At December 31, 2019	(72)	23	(49)

The gross amount of the pre-tax reserve recorded in other comprehensive income at December 31, 2021 (amounting to a loss of $0.06 million) is expected to be reclassified to the income statements in accordance to the payments of interests in connection with the borrowings hedged by these derivative contracts, during 2021 and up to the end of the life of the borrowing in 2022.

21.    DERIVATIVE FINANCIAL INSTRUMENTS (continued)

(b) Foreign exchange contracts

From time to time, Ternium’s subsidiaries enter into derivative agreements to manage their exposure to currencies other than the $, in accordance with the Company’s policy for derivative instruments.

As of December 31, 2021, the notional amount on these agreements amounted to $100.0 million.

Furthermore, during 2021, 2020 and 2019, Ternium Colombia S.A.S. has entered into non-deliverable forward agreements to manage the exposure of certain actual and future trade receivables denominated in its local currency. As of December 31, 2021, the notional amount on these agreements amounted to $87.8 million.

During 2021, 2020 and 2019, Ternium Mexico entered into several forward agreements mainly to manage the exchange rate exposure generated by future payables in EUR related to the investment plan in Pesquería and other standard liabilities in EUR . Furthermore, a minor part of the forward agreements were carried out in order to manage the exchange rate exposure arising from sales in EUR. As of December 31, 2021, the aggregate notional amount on these agreements amounted to $44.0 million.

In addition, during 2021 and 2020, Ternium Investments S.à r.l. entered into non-deliverable forward agreements to manage the exchange rate exposure generated by actual and future trade receivables denominated in Colombian pesos related to the commissioning of the plant and the business of its subsidiary, Ternium del Atlántico.

CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS

Disclosure of commitments and contingencies [Abstract]

CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS

CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS

Ternium is from time to time subject to various claims, lawsuits and other legal proceedings, including customer, employee, tax and environmental-related claims, in which third parties are seeking payment for alleged damages, reimbursement for losses, or indemnity. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure.

Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties and, therefore, the probability of loss and an estimation of damages are difficult to ascertain. Accordingly, with respect to a large portion of such claims, lawsuits and other legal proceedings, Ternium is unable to make a reliable estimate of the expected financial effect that will result from ultimate resolution of the proceeding. In those cases, Ternium has not accrued a provision for the potential outcome of these cases.

If a potential loss from a claim, lawsuit or other proceeding is considered probable and the amount can be reasonably estimated, a provision is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements and take into consideration litigation and settlement strategies. In a limited number of ongoing cases, Ternium was able to make a reliable estimate of the expected loss or range of probable loss and has accrued a provision for such loss but believes that publication of this information on a case-by-case basis would seriously prejudice Ternium’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in these cases, the Company has disclosed information with respect to the nature of the contingency but has not disclosed its estimate of the range of potential loss.

The Company believes that the aggregate provisions recorded for potential losses in its consolidated financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Ternium could incur a charge to earnings which could have a material adverse effect on Ternium’s results of operations, financial condition, net worth and cash flows.

(i) Tax claims and other contingencies

(a) Companhia Siderúrgica Nacional (CSN) – Tender offer litigation

In 2013, the Company was notified of a lawsuit filed in Brazil by Companhia Siderúrgica Nacional, or CSN, and various entities affiliated with CSN against Ternium Investments, its subsidiary Ternium Argentina, and TenarisConfab. The entities named in the CSN lawsuit had acquired a participation in Usiminas in January 2012. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL 28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group; Ternium Investments and Ternium Argentina’s respective shares in the offer would be 60.6% and 21.5%.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals of São Paulo maintained the understanding of the first instance court. On March 6, 2017, CSN filed a motion for clarification against the decision of the court of appeals, which was rejected on July 19, 2017. On August 18, 2017, CSN filed with the court of appeals an appeal seeking the review and reversal of the decision issued by the court of appeals by the Superior Court of Justice. On March 5, 2018, the court of appeals ruled that CSN’s appeal did not meet the requirements for review by the Superior Court of Justice and rejected such appeal. On May 8, 2018, CSN appealed against such ruling and on January 22, 2019, the court of appeals rejected such appeal and ordered that the case be submitted to the Superior Court of Justice. On September 10, 2019, the Superior Court of Justice declared CSN’s appeal admissible. The Superior Court of Justice will review the case and will then render a decision on the merits. The Superior Court of Justice is restricted to the analysis of alleged violations to federal laws and cannot assess matters of fact.

Ternium continues to believe that all of CSN’s claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator (CVM) in February 2012 and December 2016, and the first and second instance court decisions referred to above. Accordingly, no provision has been recorded in these Consolidated Financial Statements.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(b) Shareholder claims relating to the October 2014 acquisition of Usiminas shares

On April 14, 2015, the staff of the CVM, determined that an acquisition of additional ordinary shares of Usiminas by Ternium Investments made in October 2014, triggered a requirement under applicable Brazilian laws and regulations for Usiminas’ controlling shareholders to launch a tender offer to all non-controlling holders of Usiminas ordinary shares. The CVM staff’s determination was made further to a request by NSSMC and its affiliates, who alleged that Ternium’s 2014 acquisition had exceeded a threshold that triggers the tender offer requirement. In the CVM staff’s view, the 2014 acquisition exceeded the applicable threshold by 5.2 million shares. On April 29, 2015, Ternium filed an appeal to be submitted to the CVM’s Board of Commissioners. On May 5, 2015, the CVM staff confirmed that the appeal would be submitted to the Board of Commissioners and that the effects of the staff’s decision would be stayed until such Board rules on the matter.

On June 15, 2015, upon an appeal filed by NSSMC, the CVM staff changed its earlier decision and stated that the obligation to launch a tender offer would fall exclusively on Ternium. Ternium’s appeal has been submitted to the CVM’s Board of Commissioners,which has no set timeframe to resolve on the matter. In addition, on April 18, 2018, Ternium filed a petition with the CVM’s reporting Commissioner requesting that the applicable threshold for the tender offer requirement be recalculated taking into account the new ordinary shares issued by Usiminas in connection with its 2016 BRL 1 billion capital increase and that, in light of the replenishment of the threshold that would result from such recalculation, the CVM staff’s 2015 determination be set aside.In the event the appeal is not successful, under applicable CVM rules Ternium may elect to sell to third parties the 5.2 million shares allegedly acquired in excess of the threshold, in which case no tender offer would be required.

(c) Potential Mexican income tax adjustment

In March 2015, the Mexican tax authorities, as part of a tax audit to Ternium Mexico with respect to fiscal year 2008, challenged the deduction by Ternium Mexico’s predecessor IMSA Acero of a tax loss arising from an intercompany sale of shares in December 2008. Although the tax authorities have not yet determined the amount of their claim, they have indicated in a preliminary report that they have observations that may result in an income tax adjustment currently estimated at approximately $56.4 million, including interest and fines. Additionally, in September 2018, the Mexican tax authority, as a result of a tax audit for the fiscal year 2011 to Ternium Mexico, as predecessor of APM, objected mainly the deduction of the tax loss remaining for the year 2008, for which the estimated income tax adjustment would be of approximately $27.6 million, including interest and fines.

Ternium Mexico requested an injunction from the Mexican courts against the audit observations for the year 2008 and the fiscal credit of the year 2011, and also filed its defense and supporting documents with the Mexican tax authorities. The injunction for the year 2008 had a favorable resolution to Ternium Mexico in August 2020; consequently, in November 2020, the Mexican tax authorities issued a new preliminary report in which continues having the same observations with different arguments that may result in the same tax adjustment as per the above-included paragraph. The Company, based on the advice of counsel, believes that an unfavorable outcome in connection with this uncertain tax position is not probable and, accordingly, no provision has been recorded in these financial statements.

(d) Fishermen associations’ claims

Civil contingencies include lawsuits brought by a number of fishermen associations on behalf of their associates, alleging that the dredge of Ternium Brasil’s deep-water port has had a negative impact on fish farming and exploitation activities in the Sepetiba Bay area in Rio de Janeiro and that, as a result, fishermen in that area had suffered damages. A provision in the amount of $24.5 million was recorded at the acquisition date in connection with this matter ($8.8 million and $10.9 million as of December 31, 2021 and 2020, respectively).

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(e) Tax assessments relating to the use of certain ICMS tax credits

The Imposto Sobre Operações Relativas à Circulação de Mercadorias e Serviços, or ICMS, is a Brazilian value-added tax on the services (inter-states) and the transfer of goods in Brazil. Payment of ICMS generates tax credits that, subject to applicable law, rules and regulations, may be either used to offset ICMS payment obligations generated in connection with domestic sales of products and services, or sold and transferred to third parties.

The Rio de Janeiro State Treasury Office is challenging the use by Ternium Brasil of ICMS tax credits generated in connection with purchases of refractory materials in the period from December 2010 through December 2016, and intends to assess taxes and impose fines on Ternium Brasil on the argument that such materials may not be qualified as raw materials or intermediary products but as goods for consumption and, accordingly, ICMS tax credits generated in connection with their purchase are not available and may not be used to offset ICMS payment obligations generated in connection with Ternium Brasil’s domestic sales of carbon steel slabs. Ternium Brasil has appealed against the Rio de Janeiro State Treasury Office tax assessments and fines. A provision in the amount of $57.7 million was recorded as of the acquisition date in connection with this matter ($32.5 million and $34.9 million as of December 31, 2021 and 2020, respectively).

(f) ICMS deferral tax benefit - Action of Unconstitutionality

On March 31, 2005, through State Law No. 4,529 (Law RJ 4529), the State of Rio de Janeiro granted Ternium Brasil a tax incentive consisting of a deferral of ICMS payable by Ternium Brasil in connection with the construction and operation of the company’s Rio de Janeiro steelmaking complex. The incentive applies in respect of the acquisition of fixed assets and certain raw materials (i.e. iron ore, pellets, alloys, coke, coal and scrap) and significantly reduces input ICMS credit accumulation by Ternium Brasil. The tax incentive was granted for a period of 20 years from the commencement of the construction works for Ternium Brasil’s Rio de Janeiro steel complex.

In 2012, a Brazilian political party filed a direct action of unconstitutionality against Law RJ 4529 before the Brazilian Federal Supreme Court, claiming that the State Law should be declared unconstitutional because the tax incentive granted pursuant to Law RJ 4529 had not been approved by Brazil’s National Council of Fiscal Policy (Conselho Nacional de Política Fazendária, or CONFAZ).

In August 2017, the Brazilian Congress enacted Supplementary Law No. 160/2017, instituting a mechanism through which the States may confirm any ICMS incentives they had granted in prior years without CONFAZ approval. In furtherance of such Supplementary Law, in December 2017 the Brazilian States adopted ICMS Convention 190/2017, establishing the applicable rules and deadlines for confirming such ICMS incentives. In accordance with the ICMS Convention 190/2017, the State of Rio de Janeiro published its list of ICMS incentives, including, among others, the ICMS benefit granted to Ternium Brasil, and filed with CONFAZ all relevant documents concerning such incentives. On July 27, 2018, the Governor of Rio de Janeiro issued Decree No. 46,378, pursuant to which the State of Rio de Janeiro reconfirmed, in accordance with ICMS Convention 190/2017, the ICMS tax benefits listed in its official gazette publication made pursuant to the Convention, including, among others, Ternium Brasil’s ICMS tax benefits.

In October 2018, the State of Rio de Janeiro and the Federation of Industries of the State of Rio de Janeiro filed petitions arguing that the action of unconstitutionality against Law RJ 4529 could not be judged by the Brazilian Federal Supreme Court since, following the revalidation of such law under Supplementary Law No.160/17 and the ICMS Convention 190/2017, such action of unconstitutionality had lost its purpose. On October 20, 2020, the Reporting Justice Minister of the Brazilian Federal Supreme Court in charge of the case ruled that the action of unconstitutionality against Law RJ 4529 was impaired by the supervening loss of its object, and on November 17, 2020, the Reporting Justice Minister’s ruling became final and not subject to any further recourses or appeals.

The tax benefits accumulated under Ternium Brasil’s ICMS incentive amounted to approximately $1,089 million as of the acquisition date of Ternium Brasil on September 7, 2017. In accordance with the guidance in IFRS 3, the Company recorded as of the acquisition date a provision of $651.8 million (including estimated penalties and interest) in connection with this matter, together with an asset of $325.9 million arising from its right to recover 50% of the contingency amount from Thyssenkrupp.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

As at December 31, 2020, both the asset, which expired on September 7, 2020, of $194.1 million recorded in the Company’s financial statements arising from its right to recover 50% of the contingency amount from Thyssenkrupp and the contingent liability of $380.1 million recorded in its financial statements in connection with this matter have been derecognized. Accordingly, the Company recognized in the year ended December 31, 2020, a net gain in the amount of $186.0 million.

(ii) Commitments

The following are Ternium’s main off-balance sheet commitments:

(a) Ternium Argentina signed agreements to cover 80% of its required iron ore, pellets and iron ore fines volumes until December 31, 2024, for an estimated total amount of $890.0 million. Although they do not set a minimum amount or a minimum commitment to purchase a fixed volume, under certain circumstances a penalty is established for the party that fails of:

- 7% in case the annual operated volume is between 70% and 75% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases.

- 15% in case the annual operated volume is lower than 70% of the total volume of purchases of the Company; such percentage is applied over the difference between the actual purchased volume and the 80% of the total volume of purchases.

(b) Ternium Argentina also signed various contracts for the provision of natural gas, including Tecpetrol and Energy Consulting Services S.A., both related companies of Ternium, assuming firm commitments for a total of $82.6 million payable until April 2025. Additionally, Ternium Argentina signed contracts for gas transportation with Transportadora de Gas del Norte S.A., a related company of Ternium, assuming firm commitments for a total of $20.6 million payable until April 2028.

(c) Ternium Argentina signed an agreement with Air Liquide Argentina S.A. for the supply of oxygen, nitrogen and argon until 2021, for an aggregate amount of $16.2 million, which is due to terminate in 2037.

(d) On April 24, 2017, Ternium Mexico entered into a 25-year contract (effective as of December 1, 2016, through December 1, 2041) with Techgen, S.A. de C.V. for the supply of 699 MW (which represents 78% of Techgen’s capacity) and covers most of Ternium Mexico’s facilities electricity needs. Monthly payments are determined on the basis of capacity charges, operation costs, back-up power charges, and transmission charges. As of the seventh contract year (as long as Techgen’s existing or replacing bank facility has been repaid in full), Ternium Mexico has the right to suspend or early terminate the contract if the rate payable under the agreement is higher than the rate charged by Comisión Federal de Electricidad ("CFE") or its successors. Ternium Mexico may instruct Techgen to sell to any affiliate of Ternium Mexico, to CFE, or to any other third party all or any part of unused contracted energy under the agreement and Ternium Mexico will benefit from the proceeds of such sale.

(e) On December 20, 2000, Hylsa (Ternium Mexico’s predecessor) entered into a 25-year contract with Iberdrola Energia Monterrey, S.A. de C.V. (“Iberdrola”), a Mexican subsidiary of Iberdrola Energía, S.A., for the supply of energy to four of Ternium Mexico’s plants. On March 31, 2008, two of those plants were terminated by Iberdrola. The contracted electrical demand as of December 31, 2021, is 51.7 MW. Iberdrola currently supplies approximately 7% of Ternium Mexico’s electricity needs under this contract. Although the contract was to be effective through 2027, on April 28, 2014, Ternium Mexico and Iberdrola entered into a new supply contract and terminated the previous one. In consideration of the termination of the previous contract, Iberdrola has granted Ternium Mexico a credit of $750 thousand per MW of the 111.2 MW originally contracted capacity, resulting over time in a total value of $83.4 million. In addition, Iberdrola agreed to recognize to Ternium México $15.0 million through discounted rates. The above-mentioned credit and discount ended in June 2019 and Ternium Mexico's rates under the contract are now market rates with a 2.5% discount; however, Ternium Mexico is entitled to terminate the contract without penalty. On October 21, 2020, Ternium Mexico decided to terminate the contract effective November 15, 2021; however, this termination date was extended by common agreement with Iberdrola for an additional fixed period and the new effective termination date would be January 31, 2022.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

f) Ternium México issued a guarantee letter covering up to approximately $16.6 million of the obligations of Gas Industrial de Monterrey, S.A. de C.V. ("GIMSA"), under the natural gas trading agreement between GIMSA and BP Energía México ("BPEM"). The credit line granted by BPEM in connection with this natural gas trading agreement amounted to approximately $17.0 million. As of December 31, 2021, the outstanding amount under the natural gas trading agreement was $11.5 million, which is below the amount included in the guarantee letter issued by Ternium México.

(g) On June, 2018, Ternium Mexico entered into a loan agreement with a syndicate of banks for a $1,000 million syndicated loan facility for the purpose of financing capital expenditures, the repayment or prepayment of existing debt, and other general corporate purposes. The Company entered the Facility on June 12, 2018, and the final maturity date is on June 12, 2023, being payable in eight consecutive and equal semi-annual installments commencing on December 13, 2019. The main financial covenant that the Facility requires to meet is the consolidated net senior leverage ratio to be not greater than 3.5 to 1.00. During 2019, the facility was fully disbursed ($400 million was disbursed during 2018 and $600 million by the end of June 2019). As of December 31, 2021, the outstanding value of this loan agreement was $250 million and the Company was in compliance with all of its covenants.

(h) Ternium Mexico issued a guarantee letter covering up to approximately $61.8 million of the obligations of Techgen, S.A. de C.V. (“Techgen”), under the Clean Energy Certificates trading agreement between Techgen and Enel Green Power (“ENEL”). The amount equals the remnant balance if Techgen decides to terminate the agreement prior to the expiration date (and decreases as time of the contract passes). The contract was signed on May 25, 2018, and terminates on June 30, 2041.

(i) In June 2008, Ternium Mexico entered into an industrial gas supply agreement with Praxair Mexico for the Guerrero and Juventud facilities until December 2024, for a total amount of $421 million. In 2011, an amendment agreement added the purchase of hydrogen for the Juventud and Universidad facilities valid until April 2025. As of December 31, 2021, the agreement considers a minimum annual oxygen consumption of 96 million cubic meters, valued at approximately $4.5 million per year. The Company is in compliance with the minimum annual quotas established, which represent less than half of the average annual consumption.

(j) On May 9, 2018, Ternium Mexico entered into a 10-year contract (effective as of July 1, 2018) with Kinder Morgan Texas Pipeline L.L.C., Kinder Morgan Tejas Pipeline L.L.C. and Kinder Morgan Border Pipeline L.L.C. for the transportation of natural gas in the United States of America (Texas). The contracted capacity is 60,000 MMBTU/day and the annual cost is approximately $3.7 million.

(k) On December 30, 2019, Ternium Mexico entered into a 15-year contract (effective as of July 1, 2021) with Kinder Morgan Texas Pipeline L.L.C., Kinder Morgan Tejas Pipeline L.L.C. and Kinder Morgan Gas Natural de México S. de R.L. de C.V. for the transportation of natural gas in the United States of America (Texas) and in Mexico. The contracted capacity is 31,000 MMBTU/day and the annual cost is approximately $4.8 million.

(l) Techgen is a party to gas transportation capacity agreements with Kinder Morgan Gas Natural de Mexico, S. de R.L. de C.V., Kinder Morgan Texas Pipeline LLC and Kinder Morgan Tejas Pipeline LLC for the whole transportation capacity starting on August 1, 2016, and ending during the second half of 2036. As of December 31, 2021, the outstanding value of this commitment was approximately $206.7 million. Ternium’s exposure under the guarantee in connection with these agreements amounts to $99.2 million, corresponding to the 48% of the agreements’ outstanding value as of December 31, 2021.

(m) Ternium issued two stand-by letters of credit covering 48% of the funding of a debt service reserve account under a syndicated loan agreement between Techgen and several banks led by Citigroup Global Markets Inc., Credit Agricole Corporate and Investment Bank, and Natixis, New York Branch acting as joint bookrunners. The loan agreement dated as of February 13, 2019, amounted to $640 million and the proceeds were used by Techgen to refinance in full all amounts owed under a previous syndicated loan between Techgen and several banks, which funds were used in the construction of the facility. As of December 31, 2021, the outstanding aggregated amount under the stand-by letters of credit was $46.8 million, as a result the amount guaranteed by Ternium was approximately $22.4 million.

24.    CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(n) During 2006, CSA, the predecessor of Ternium Brasil, has entered into a 15-year contract denominated Contrato de comercialização de energia elétrica no ambiente regulado - CCEAR por disponibilidade to provide electric energy to 24 distributors starting on 2011. Under this contract, Ternium Brasil has to provide 200 MW average per year and the price is adjusted by the Brazilian inflation index. The penalty for not delivering the volume of energy of the contract is the difference between the spot price and the unit variable cost (calculated and published by the Agéncia Nacional de Energía Elétrica), calculated per hour.

(o) Ternium Brasil signed an exclusivity agreement with Vale S.A. for the purchase of iron ore (pellets, sinter feed and lump ore), which is due to terminate in 2029. The total purchased volume, in accordance with the actual production capacity, is of approximately 8.0 million tons per year. Ternium Brasil has not the obligation to take or pay the mentioned volume and only should pay logistic costs in case of not purchasing the contracted volume.

(p) Ternium Brasil, for its activity of energy generation through gas and steam turbines, signed on March 2017 a contract with GE Global Parts and Products GMBH, General Electric International Inc. and Alstom Energia Térmica e Indústria Ltda. for the maintenance services of such turbines (including the supply of spare parts) for a period of 20 years. As of December 31, 2021, the outstanding amount of this commitment was $138.3 million.

(q) Ternium Brasil also signed on November 2007 a contract with Primetals Technologies Brazil Ltda. for the provision of maintenance services at a central workshop for the entire steel mill complex, including caster maintenance for the steel plant. As of December 31, 2021, the outstanding amount of the mentioned services was approximately $44.7 million and is due to terminate on November 2024.

This agreement was automatically renewed for another two years, is due to terminate on December 2021 and can be interrupted by common agreement due to free market conditions' changes. The outstanding amount was of $24.1 million (or 61.3 million m3) as of December 31, 2021. Ternium Brasil is currently purchasing more than the minimum volume required by the contract, which is 85% of the volume mentioned before.

(t) Ternium Brasil signed on May 2019 a contract with LSI Logistica S.A. for mobile equipment rental. This agreement is due to terminate on May 2024 and the outstanding amount was $7.2 million as of December 31, 2021. The contract only has a penalty in case of anticipated termination.

(u) The acquisition of Ternium Brasil Ltda. was mainly financed through an unsecured 5-year syndicated facility in the principal amount of $1.5 billion granted to the Company’s subsidiary, Ternium Investments S.àr.l., by a syndicate of banks. The facility is to be repaid in eight consecutive and equal semi-annual installments, commencing on March 5, 2019, and has been guaranteed by the Company’s subsidiary, Ternium México, S.A. de C.V. The borrower and the guarantor are subject to certain covenants customary for transactions of this type, including limitations on liens and encumbrances, transactions with affiliates, consolidations and mergers and restrictions on investments. The guarantor is additionally subject to limitations on the sale of certain assets and compliance with a leverage ratio. There are no limitations to the payment of dividends applicable to the borrower or the guarantor, except, with respect to the borrower, upon an event of default under the facility. During 2018 and 2019, the Company made prepayments of principal for $375 million and $725 million, respectively. As of December 31, 2021, the outstanding value of this syndicated facility was $375 million and both the borrower and the guarantor were in compliance with all of its covenants.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Disclosure of significant accounting policies [Abstract]

RECENTLY ISSUED ACCOUNTING PRONOUCNEMENTS

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

The following amendments, standards and interpretations have been applied on the year starting January 1, 2021:

International Financial Reporting Standard 7, “Financial Instruments: Disclosures”, International Financial Accounting Standard 9, “Financial Instruments” and International Accounting Standard 39, “Financial Instruments: Recognition and Measurement” - Interest Rate Benchmark Reform

The IASB has issued amendments to IFRS 7 “Financial Instruments: Disclosures”, IFRS 9 “Financial Instruments” and IAS 39 “Financial Instruments: Recognition and Measurement” which provide certain reliefs in relation to interest rate benchmark reforms. The reliefs relate to hedge accounting and have the effect that the reforms should not generally cause hedge accounting to terminate. However, any hedge ineffectiveness should continue to be recorded in the income statement.

The Company's management has assessed the effects of applying these amendments on the Company’s financial statements and has not identified any material impact in the application of these amendments.

International Financial Reporting Standard 16, “Leases” – Amendments on Covid-19-related Rent Concessions

In May 2020, the IASB made an amendment to IFRS 16 “Leases” in the context of the COVID-19 pandemic and its impact on rent concessions granted to lessees. Such concessions might take a variety of forms, including payment holidays and deferral of lease payments, which provides lessees with an option to treat qualifying rent concessions in the same way as they would if they were not lease modifications. In many cases, this will result in accounting for the concessions as variable lease payments in the period in which they are granted. Entities applying the practical expedients must disclose this fact, whether the expedient has been applied to all qualifying rent concessions or, if not, information about the nature of the contracts to which it has been applied, as well as the amount recognized in profit or loss arising from the rent concessions.

The Company's management has assessed the effects of applying this amendment on the Company’s financial statements and has not identified any lease agreements which may be impacted by the application of this amendment.

The following standards, amendments to standards and interpretations are not mandatory for the financial year beginning January 1, 2021, and have not been early adopted:

International Accounting Standard 12, “Income taxes” - Amendments

The IASB has issued amendments to IAS 12 “Income taxes”, which introduce a further exception from the initial recognition exemption. Under the amendments, an entity does not apply the initial recognition exemption for transactions that give rise to equal taxable and deductible temporary differences. Depending on the applicable tax law, equal taxable and deductible temporary differences may arise on initial recognition of an asset and liability in a transaction that is not a business combination and affects neither accounting nor taxable profit.

The Company's management has assessed the effects of applying these amendments on the Company’s financial statements and has not identified any material impact in the application of these amendments.

27.    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (continued)

Other standards and interpretations non-significant for the Company’s financial statements:

–Amendments to IFRS 10 and IAS 28 - Sale or contribution of assets between an investor and its associate or joint venture

–Amendments to IAS 1 - Classification of Liabilities as Current or Non-current

–Amendments to IFRS 3 - Reference to the Conceptual Framework

FINANCIAL RISK MANAGEMENT

12 Months Ended

Dec. 31, 2021

Disclosure of notes and other explanatory information [Abstract]

FINANCIAL RISK MANAGEMENT

FINANCIAL RISK MANAGEMENT

1)    Financial risk factors

Ternium’s activities expose the Company to a variety of risks: market risk (including the effects of changes in foreign currency exchange rates, interest rates and commodities prices), credit risk and liquidity risk.

Ternium’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the financial performance. Ternium’s subsidiaries may use derivative financial instruments to hedge certain risk exposures.

1.1) Market Risk

(i) Foreign exchange rate risk

Ternium operates and sells its products in different countries, and as a result is exposed to foreign exchange rate volatility. Ternium’s subsidiaries may use derivative contracts in order to hedge their exposure to exchange rate risk derived from their trade and financial operations.

Ternium’s foreign exchange policy is to minimize the negative impact of fluctuations in the value of other currencies with respect to the U.S. dollar. Ternium’s subsidiaries monitor their net cash flows in currencies other than the U.S. dollar, and analyze potential hedging according to market conditions. This hedging can be carried out by netting positions or by financial derivatives. However, regulatory or legal restrictions in the countries in which Ternium’s subsidiaries operate, could limit the possibility of the Company carrying out its hedging policy.

Ternium has foreign operations, whose net assets are exposed to foreign currency translation risk, some of which may impact net income.

The following table shows a breakdown of Ternium’s assessed financial position exposure to currency risk as of December 31, 2021.

Exposure to functional currency	$ million
EU euro (EUR)	(78)
Argentine peso (ARS)	297
Mexican peso (MXN)	(1,255)
Brazilian real (BRL)	66
Colombian peso (COP)	(52)
Other currencies	(1)

    

28.    FINANCIAL RISK MANAGEMENT (continued)

The main relevant exposures correspond to:

(a)Argentine peso vs. U.S. dollar

If the Argentine peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $3.2 million and $1.0 million as of December 31, 2021 and 2020, respectively.

(b)Mexican peso vs. U.S. dollar

If the Mexican peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $12.5 million and $5.9 million as of December 31, 2021 and 2020, respectively.

(c)Colombian peso vs. U.S. dollar

If the Colombian peso had weakened by 1% against the U.S. dollar, it would have generated a pre-tax gain of $0.5 million and $0.2 million as of December 31, 2021 and 2020, respectively.

(d) Brazilian real vs. U.S. dollar

If the Brazilian real had weakened by 1% against the U.S. dollar, it would have generated a pre-tax loss of $0.5 million and $1.1 million as of December 31, 2021 and 2020, respectively.

We estimate that if the Argentine peso, Mexican peso, Colombian peso and Brazilian real had weakened simultaneously by 1% against the U.S. dollar with all other variables held constant, total pre-tax income for the year would have been $9.4 million higher ($4.0 million higher as of December 31, 2020), as a result of foreign exchange gains/losses on translation of U.S. dollar-denominated financial position, mainly trade receivables, trade payables, lease liabilities, borrowings and other liabilities.

Considering the same variation of the currencies against the U.S. dollar of all net investments in foreign operations amounting to $681.7 million, the currency translation adjustment included in total equity would have been $6.7 million lower, arising mainly from the adjustment on translation of the equity related to the Brazilian real during the year 2021.

(ii) Interest rate risk

Ternium manages its exposure to interest rate volatility through its financing alternatives and hedging instruments. Borrowings issued at variable rates expose the Company to the risk of increased interest expense in the event of a raise in market interest rates, while borrowings issued at fixed rates expose the Company to a variation in its fair value. The Company’s interest-rate risk mainly arises from long-term borrowings that bear variable-rate interest that is partially fixed through different derivative transactions, such as interest rate swaps.

Ternium’s nominal weighted average interest rate for its debt instruments, which do not include neither the effect of derivative financial instruments, nor the devaluation of the local currencies, was 1.45% and 1.43% as of December 31, 2021 and 2020, respectively. These rates were calculated using the rates set for each instrument in its corresponding currency and weighted using the dollar-equivalent outstanding principal amount of each instrument.

Ternium’s total variable interest rate debt amounted to $1,304 million (88.2% of total borrowings) at December 31, 2021 and $1,593 million (92.5% of total borrowings) at December 31, 2020.

If interest rates on the aggregate average notional of U.S. dollar denominated borrowings held during 2021, excluding borrowings with derivatives contracts mentioned in Note 21 (a), had been 100s basis points higher with all other variables held constant, total pre-tax income for the year ended December 31, 2021 would have been $17.3 million lower ($20.3 million lower as of December 31, 2020).

Effect of IBOR reform

Reform and replacement of various inter-bank offered rates (‘IBORs’) has become a priority for regulators. Most IBOR rates stopped being published by December 31, 2021, while certain U.S. dollar LIBOR rates would stop being published by June 30, 2023.

Ternium would not be required to transition to alternative interest rate benchmarks as of December 31, 2021, as most of its outstanding borrowings with floating interest rates based in U.S. dollar LIBOR rates will be fully repaid before June 30, 2023 and such LIBOR rates will continue to be published until such date. All newly transacted floating rate financial liabilities will be linked to an alternative benchmark rate (e.g. SOFR + spread adjustments).

Under any specific requests of any of its counterparties in these outstanding borrowings, Ternium will negotiate to perform a transition of legacy IBOR-based financial instruments to alternative benchmark interest rates. The Company has prepared a sensitivity analysis considering this situation and concluded that no material impacts could derive from this change. The Company is also enhancing its IT systems and internal processes to ensure smooth transition from IBOR to alternative benchmark interest rates.

1.2) Credit risk

Credit risk arises from cash and cash equivalents, deposits with banks and financial institutions, as well as credit exposures to customers, including outstanding receivables and committed transactions. Ternium’s subsidiaries have credit guidelines in place to ensure that derivative and treasury counterparties are limited to high credit quality financial institutions.

Ternium invests in financial assets with a minimum credit rating of investment grade established by an international qualification agency renowned in the financial market, in line with corporate investment portfolio policies. Approximately 57.3% of the Company’s liquid financial assets correspond to investment grade rated instruments as of December 31, 2021, in comparison with approximately 61.1% as of December 31, 2020. The investments in financial assets are as follows:

	At December 31, 2021	At December 31, 2020
Cash and cash equivalents	1,276,605	537,882
Other Investments - Current and Non-Current	1,357,485	816,157
Fixed Income (time-deposit, zero-coupon bonds, commercial papers)	863,416	579,917
Deposit certificates	710,996	451,857
Commercial papers	92,729	128,060
Other	59,691	—
Bonds and other fixed income	490,806	233,611
Non - U.S. government securities	367,333	135,671
Corporate securities	123,473	97,940
Other notes	3,263	2,629

    

Ternium has no significant concentrations of credit risk from customers. No single customer accounts for more than ten percent of Ternium’s sales. Ternium’s subsidiaries have policies in place to ensure that sales are made to customers with an appropriate credit history, and that credit insurances, letters of credit or other instruments are requested to reduce credit risk whenever deemed necessary. The subsidiaries maintain allowances for potential credit losses. The utilization of credit limits is regularly monitored.

Trade and other receivables are carried at face value less allowance for doubtful accounts, if applicable. This amount does not differ significantly from fair value. The other receivables do not contain significant impaired assets.

As of December 31, 2021, trade receivables total $1,767.4 million ($918.4 million as of December 31, 2020). These trade receivables are collateralized by guarantees under letter of credit and other bank guarantees of $30.3 million ($1.3 million as of December 31, 2020), credit insurance of $800.1 million ($422.8 million as of December 31, 2020) and other guarantees of $8.4 million ($7.3 million as of December 31, 2020).

As of December 31, 2021, trade receivables of $1,681.5 million ($892.3 million as of December 31, 2020) were fully performing.

28.    FINANCIAL RISK MANAGEMENT (continued)´

As of December 31, 2021, trade receivables of $95.4 million ($36.6 million as of December 31, 2020) were past due (mainly up to 180 days).

The amount of the allowance for doubtful accounts was $9.5 million as of December 31, 2021 ($10.5 million as of December 31, 2020).

The carrying amounts of the Company’s trade and other receivables as of December 31, 2021, are denominated in the following currencies:

Currency	$ million
US dollar ($)	1,674
EU euro (EUR)	3
Argentine peso (ARS)	43
Mexican peso (MXN)	214
Brazilian real (BRL)	300
Colombian peso (COP)	68
Other currencies	1
	2,303

1.3)    Liquidity risk

Management maintains sufficient cash and marketable securities and credit facilities to finance normal operations. Management monitors rolling forecasts of the group’s liquidity reserve on the basis of expected cash flow.

The table below analyses financial liabilities into relevant maturity groups based on the remaining period at the date of the statement of financial position to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

Total	1,982	184	561	39	144

(1) These amounts do not include the effect of derivative financial instruments.

As of December 31, 2021, total cash and cash equivalents and other current and non-current investments less borrowings amounted to $1,154.8 million.

1.4)    Capital risk

Ternium seeks to maintain an adequate debt/equity ratio considering the industry and the markets where it operates. The year-end ratio debt over debt plus equity is 0.11 and 0.17 as of December 31, 2021 and 2020, respectively. The Company does not have to comply with regulatory capital adequacy requirements as known in the financial services industry.

2)    Financial instruments by category and fair value hierarchy level

The accounting policies for financial instruments have been applied to the line items below. According to the scope and definitions set out in IFRS 7 and IAS 32, employers’ rights and obligations under employee benefit plans, and non-financial assets and liabilities such as advanced payments and income tax payables, are not included.

Fair Value by Hierarchy

Following the requirements contained in IFRS 13, Ternium categorizes each class of financial instrument measured at fair value in the statement of financial position into three levels, depending on the significance of the judgment associated with the inputs used in making the fair value measurements:

–Level 1 comprises financial assets and financial liabilities whose fair values have been determined on the basis of quoted prices (unadjusted) in active markets for identical assets or liabilities.

–Level 2 includes financial assets and financial liabilities for which fair values have been estimated using inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

–Level 3 comprises financial instruments for which inputs to estimate fair value of the assets or liabilities are not based on observable market data (unobservable inputs).

The following table presents the assets and liabilities that are measured at fair value as of December 31, 2021 and 2020:

	Fair value measurement as of December 31, 2021 (in $ thousands):
Description	Total	Level 1	Level 2	Level 3 (*)
Financial assets at fair value through profit or loss / OCI
Cash and cash equivalents	692,529	692,529	—	—
Other investments	735,654	668,056	39,777	27,821
Derivative financial instruments	4,353	—	4,353	—
Total assets	1,432,536	1,360,585	44,130	27,821
Financial liabilities at fair value through profit or loss / OCI
Derivative financial instruments	1,889	—	1,889	—
Total liabilities	1,889	—	1,889	—

	Fair value measurement as of December 31, 2020 (in $ thousands):
Description	Total	Level 1	Level 2	Level 3 (*)
Financial assets at fair value through profit or loss / OCI
Cash and cash equivalents	259,020	259,020	—	—

Financial liabilities at fair value through profit or loss / OCI
Derivative financial instruments	6,358	—	6,358	—
Total liabilities	6,358	—	6,358	—

(*) The fair value of financial instruments classified as level 3 is not obtained from observable market information, but from measurements of the asset portfolio at market value provided by the fund manager. The evolution of such instruments during the years ended December 31, 2021 and 2020, corresponds to the initial investment and to the changes in its fair value, as follows:.

	Guarantee fund companies		Non - U.S. government securities		Corporate securities
At December 31, 2020	2,629	—	—	—	—
Additions	—		7,863		16,695
Changes in fair value	1,189		—		—
Net foreign exchange gain	(555)		—		—
At the end of the year	3,263		7,863		16,695

28.    FINANCIAL RISK MANAGEMENT (continued)

There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy and there were no transfers from Level 1 and Level 2 to Level 3.

The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by Ternium is the current mid price. These instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.

The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is determined by using valuation techniques which maximize the use of observable market data when available and rely as little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the instrument is included in Level 2. Ternium values its assets and liabilities included in this level using mid prices, interest rate curves, broker quotations, current exchange rates and forward rates volatilities obtained from market contributors as of the valuation date.

If one or more of the significant inputs are not based on observable market data, the instruments are included in Level 3. Ternium values its assets and liabilities in this level using observable market inputs, information provided by fund managers and management assumptions which reflect the Company’s best estimate on how market participants would price the asset or liability at measurement date.

3)    Accounting for derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized in the statement of financial position at cost and subsequently measured at fair value. Changes in fair value are disclosed under “Other financial income (expenses), net” line item in the income statement. Ternium does not hedge its net investments in foreign entities.

Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly interest rate swaps). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized within other comprehensive income. Amounts accumulated in other comprehensive income are recognized in the income statement in the same period than any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected on the statement of financial position.

For transactions designated and qualifying for hedge accounting, Ternium documents at inception the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. At December 31, 2021, the effective portion of designated cash flow hedges amounts to $(0.04) million (net of taxes) and is included as “Cash flow hedges” line item in the statement of comprehensive income.

28.    FINANCIAL RISK MANAGEMENT (continued)

The fair values of various derivative instruments used for hedging purposes are disclosed in Note 21. The full fair value of a hedging derivative is classified as a non-current asset or liability when the remaining maturity of the hedged item is more than 12 months and as a current asset or liability when the remaining maturity of the hedged item is less than 12 months.

Changes in the fair value of any derivative instruments that do not qualify for hedge accounting under IAS 39 are recognized immediately in the income statement.

4)    Fair value estimation

The estimated fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

For the purpose of estimating the fair value of financial assets and liabilities with maturities of less than one year, the Company uses the market value less any estimated credit adjustments. For other investments, the Company uses quoted market prices.

As most borrowings incorporate floating rates that approximate market rates and the contractual repricing occurs mostly every one month, the fair value of the borrowings approximates their carrying amount and it is not disclosed separately.

In assessing the fair value of derivatives and other financial instruments, Ternium uses a variety of methods, including, but not limited to, estimated discounted value of future cash flows using assumptions based on market conditions existing at each year end.

THE COVID-19 PANDEMIC AND ITS IMPACT ON TERNIUM

THE COVID-19 PANDEMIC AND ITS IMPACT ON TERNIUM

A novel strain of coronavirus (SARS-CoV-2) was reported to have surfaced in China in December 2019, spreading to the rest of the world in the first quarter of 2020. In March 2020, the World Health Organization declared COVID-19, the disease caused by the SARS-CoV-2 virus, a global pandemic. The COVID-19 outbreak impacted economic activity worldwide.

In order to safeguard the health and safety of its employees, customers and suppliers, Ternium continues to apply preventive measures, including remote working under a hybrid work scheme for salaried employees, implementing a special operations protocol to ensure social distancing and providing medical assistance and supplies to onsite employees. As of the date of these consolidated financial statements, remote work and other work arrangements have not materially adversely affected Ternium's ability to conduct operations. In addition, these alternative working arrangements have not adversely affected our financial reporting systems, internal control over financial reporting or disclosure controls and procedures.

Even though the main negative effects of the pandemic in steel demand are behind us, and as of the issue date of these consolidated financial statements all of Ternium’s industrial facilities continued working at normal production levels, there remains considerable uncertainty about the future duration and extent of the pandemic with new and more contagious variants of the virus appearing and the vaccination programs not yet completed around the world.

29.    THE COVID-19 PANDEMIC AND ITS IMPACT ON TERNIUM (continued)

With total cash and cash equivalents and other current and non-current investments less borrowings of $1.2 billion as of December 31, 2021 and a manageable debt amortization schedule, Ternium has in place non-committed credit facilities and management believes it has adequate access to the credit markets. Considering its financial position and the funds provided by operating activities, management believes that the Company has sufficient resources to satisfy its current working capital needs and service its debt. Management also believes that Ternium's liquidity and capital resources give adequate flexibility to manage the capital spending programs and address short-term changes in business conditions, and that it is unlikely that Ternium will not be able to meet its financial covenants. Similarly, management does not expect to incur any material COVID-19-related contingencies.

FOREIGN EXCHANGE RESTRICTIONS IN ARGENTINA

FOREIGN EXCHANGE RESTRICTIONS IN ARGENTINA

Ternium’s Argentine subsidiary, Ternium Argentina S.A., is currently operating in a complex and volatile economic environment. Beginning in September 2019, the Argentine government has imposed and continues to impose significant restrictions on foreign exchange transactions. Restrictions have tightened over time. These measures, however, have not had a significant effect on Ternium Argentina’s ability to purchase U.S. dollars at the prevailing official exchange rate for all of its imports of goods and for the acquisition of services from unrelated parties. By contrast, access to the Argentine foreign exchange market to distribute dividends or to pay royalties to related parties at the prevailing official exchange rate generally requires prior Argentine Central Bank approval, which is rarely, if ever, granted. In March 2022, the Argentine government imposed further restrictions to access the foreign exchange market for payment of imports. If such restrictions are maintained, or are further tightened, Ternium Argentina could be restricted from making payment of imports for key steelmaking inputs which would adversely affect its operations, or would need to resort to alternative, more expensive arrangements, which would affect its results of operations.

Ternium Argentina stated in its annual accounts as of and for the year ended December 31, 2021, that revenues amounted to $3,425 million (2020: $1,823 million), net profit from continuing operations to $930 million (2020: $268 million), total assets to $4,798 million (2020: $3,273 million), total liabilities to $541 million (2020: $430 million) and shareholders’ equity to $4,257 million (2020: $2,843 million).

Ternium Argentina’s cash and cash equivalents and other investments amounted to $965 million as of December 31, 2021:

- $306 million in Argentine pesos-denominated instruments, mainly inflation-linked financial instruments ($155 million), such as bonds and bills adjusted by CER (Reference Stabilization Coefficient), and mutual funds ($135 million).

- $242 million in Argentine pesos-denominated instruments with underlying assets to the U.S. dollar (Cedears - Argentine deposit certificates)

- $417 million in U.S. dollars-denominated instruments, mainly sovereign bonds issued by the Argentine State and payable in U.S. dollars, national Treasury bonds related to the official exchange rate and negotiable obligations and promissory notes issued by national export driven companies in U.S. dollars and payable in Argentine pesos.

Ternium Argentina’s financial position in ARS as of December 31, 2021, amounted to $612 million in monetary assets and $290 million in monetary liabilities. All of Ternium Argentina’s ARS-denominated assets and liabilities are valued at the prevailing official exchange rate. Although most of Ternium Argentina’s cash holdings are either denominated or payable in ARS, this exposure to the ARS as of December 31, 2021, was diminished due to hedging strategies using derivative instruments amounting to $100 million.

As the context of volatility and uncertainty remains in place as of the issue date of these consolidated financial statements, additional regulations that could be imposed by the Argentine government could further restrict Ternium Argentina’s ability to access the official foreign exchange market.

SUBSEQUENT EVENTS - THE RUSSIA-UKRAINE ARMED CONFLICT	SUBSEQUENT EVENTS - THE RUSSIA-UKRAINE ARMED CONFLICTOn February 24, 2022, Russia launched a military attack on Ukraine. In response, the United States, the United Kingdom, and the European Union, among other countries, have imposed a wave of sanctions against certain Russian institutions, companies and citizens. As a result of the armed conflict and related sanctions, energy prices have spiked and foreign trade transactions involving Russian and Ukrainian counterparties have been severely affected.Russia has a significant participation in the international trade of steel slabs, iron ore pellets, metallurgical coal, pulverized coal for injection, which are relevant inputs for Ternium’s operations. In addition, Ukraine has a relevant participation in the international trade of steel slabs and iron ore pellets. The availability and pricing of these inputs in the international markets are expected to be volatile and could result in limitations to Ternium’s production levels and higher costs, affecting the Company’s profitability and results of operations. As a result of the economic sanctions imposed on Russia, Ternium or its contractors (including shipping companies) may not be able to continue purchasing or transporting products from, or making payments to, Ukrainian or Russian suppliers or counterparties; and the Company may not be able to promptly procure such raw materials from other suppliers, or may be required to purchase raw materials at increased prices.

ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2021

Disclosure of significant accounting policies [Abstract]

Group accounting

Subsidiary companies and transactions with non-controlling interests

Subsidiaries are all entities over which the Company has control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company uses the acquisition method of accounting to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred and the equity interests issued by the Company. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at the fair values at the acquisition date. Indemnification assets are recognized at the same time that the Company recognizes the indemnified item and measures them on the same basis as the indemnified item, subject to the need for a valuation allowance for uncollectible amounts. The Company measures the value of a reacquired right recognized as an intangible asset on the basis of the remaining contractual term of the related contract regardless of whether market participants would consider potential contractual renewals in determining its fair value.

On an acquisition-by-acquisition basis, the Company recognizes any non-controlling interest in the acquiree at the non-controlling interest's proportionate share of the acquiree's net assets.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the Company's share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

The measurement period is the earlier of the date that the acquirer receives the information that it is looking for or cannot obtain the information and one year after the acquisition date. Where the accounting for a business combination is not complete by the end of the reporting period in which the business combination occurred provisional amounts are reported.

The Company treats transactions with non-controlling interests as transactions with equity owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

3.    ACCOUNTING POLICIES (continued)

When the Company ceases to have control or significant influence, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

Inter-company transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the group. However, the fact that the functional currency of some subsidiaries is their respective local currency, generates some financial gains (losses) arising from intercompany transactions, that are included in the consolidated income statement under Other financial expenses, net.

(2)    Investments in non-consolidated companies

Associated companies are those entities in which Ternium has significant influence, but which it does not control.

Joint arrangements are understood as combinations in which there are contractual agreements by virtue of which two or more companies hold an interest in companies that undertake operations or hold assets in such a way that any financial or operating decision is subject to the unanimous consent of the partners. A joint arrangement is classed as a joint operation if the parties hold rights to its assets and have obligations in respect of its liabilities or as a joint venture if the venturers hold rights only to the investee's net assets.

Investments in non-consolidated companies (associated companies and joint ventures) are accounted for using the equity method of accounting. Under this method, interests in joint ventures and associates are initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Company’s share of the post-acquisition profits or losses in the income statement, and its share of post-acquisition changes in reserves recognized in reserves and in other comprehensive income in the income statement. Unrealized gains on transactions among the Company and its non-consolidated companies are eliminated to the extent of the Company’s interest in such non-consolidated companies; unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. When the Company’s share of losses in a non-consolidated company equals or exceeds its interest in such non-consolidated company, the Company does not recognize further losses unless it has incurred obligations or made payments on behalf of such non-consolidated company.

The Company’s investment in associates and joint ventures includes notional goodwill identified on acquisition.

The Company determines at each reporting date whether there is any objective evidence that the investment is impaired. If this is the case, the group calculates the amount of impairment as the difference between the recoverable amount of the investment and its carrying value and recognizes the amount within “Equity on earnings (losses) of non-consolidated companies”.

Foreign currency translation

Functional and presentation currency

Items included in the financial statements of each of the Company's subsidiaries and associated companies are measured using the currency of the primary economic environment in which the entity operates (the "functional currency"). Except for the non-consolidated companies whose functional currencies are their local currencies, Ternium determined that the functional currency of its subsidiaries is the U.S. dollar. Although Ternium is located in Luxembourg, it operates in several countries with different currencies. The $ is the currency that best reflects the economic substance of the underlying events and circumstances relevant to Ternium as a whole.

(2)    Subsidiary companies

The results and financial position of all the group entities (except for the ones which operated in a hyperinflationary economy) that have a functional currency different from the presentation currency, are translated into the presentation currency as follows:

(i) assets and liabilities are translated at the closing rate of each statement of financial position;

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

(iii) all resulting translation differences are recognized within other comprehensive income.

In the case of a sale or other disposition of any such subsidiary, any accumulated translation differences would be recognized in the income statement as part of the gain or loss on sale.

(3)    Transactions in currencies other than the functional currency

Transactions in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation where items are re-measured.

At the end of each reporting period: (i) monetary items denominated in currencies other than the functional currency are translated using the closing rates, (ii) non-monetary items that are measured in terms of historical cost in a currency other than the functional currency are translated using the exchange rates prevailing at the date of the transactions; and (iii) non-monetary items that are measured at fair value in a currency other than the functional currency are translated using the exchange rates prevailing at the date when the fair value was determined.

Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than the functional currency are recorded as gains and losses from foreign exchange and included in "Other financial income (expenses), net" in the consolidated income statement, except when deferred in equity as qualifying cash flow hedges and qualifying net investment hedges. Translation differences on non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the "fair value gain or loss," while translation differences on non-monetary financial assets such as equities classified as fair value through other comprehensive income are included in other gains/(losses).

Financial instruments

Non derivative financial instruments

Non derivative financial instruments comprise investments in equity and debt securities, trade and other receivables, cash and cash equivalents, loans and borrowings, and trade and other payables.

The Company classifies its financial instruments in the following measurement categories:

–Amortized cost: instruments that are held for collection or repayment of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. Interest income and expenses from these financial instruments are included in finance income or expense using the effective interest rate method. Any gain or loss arising on derecognition is recognized directly in profit or loss and presented in finance income or expense, together with foreign exchange gains and losses. Impairment losses are presented as separate line items in the statement of profit or loss.

–Fair value through other comprehensive income (“FVOCI”): financial assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in OCI is reclassified from equity to profit or loss and recognized in other gains/(losses). Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses) and impairment expenses are presented as separate line item in the statement of profit or loss.

–Fair value through profit or loss (“FVPL”): financial instruments that do not meet the criteria for amortized cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognized in profit or loss and presented net within other gains/(losses) in the period in which it arises.

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

For financial instruments measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the group has made an irrevocable election at the time of initial recognition to account for the equity investment at FVOCI.

At initial recognition, the Company measures a financial instrument at its fair value plus, in the case of a financial instrument not at FVPL, transaction costs that are directly attributable to the acquisition of the financial instrument. Transaction costs of financial instruments carried at FVPL are expensed in profit or loss. Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset.

3.    ACCOUNTING POLICIES (continued)

The classification depended on the nature and purpose of the financial assets and was determined at the time of initial recognition.

Financial assets and liabilities were recognized and derecognized on the settlement date.

Financial assets were initially measured at fair value, net of transaction costs, except for those financial assets classified as financial assets at fair value through profit or loss.

Financial liabilities, including borrowings, were initially measured at fair value, net of transaction costs and subsequently measured at amortized cost using the effective interest method, with interest expense recognized on an effective yield basis.

Impairment of financial assets

The Company assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk.

For trade receivables, the Company applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognized from initial recognition of the receivables, see note 3 (i) for further details.

For loans and receivables category and for held-to-maturity investments, the amount of the loss was measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset's original effective interest rate. The carrying amount of the asset was reduced and the amount of the loss was recognized in the consolidated income statement.

If, in a subsequent period, the amount of the impairment loss decreased and the decrease could be related objectively to an event occurring after the impairment was recognized, the reversal of the previously recognized impairment loss was recognized in the consolidated income statement.

Derivative financial instruments

Information about accounting for derivative financial instruments and hedging activities is included in Note 28 "Financial Risk management" and Note 3 (y).

Property, plant and equipment

Property, plant and equipment

Land and buildings comprise mainly factories and offices. All property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation and accumulated impairment (if applicable), except for land, which is carried at acquisition cost less accumulated impairment (if applicable). There are no material residual values for property, plant and equipment items.

Major overhaul and rebuilding expenditures are recognized as a separate asset when future economic benefits are expected from the item, and the cost can be measured reliably.

Ordinary maintenance expenses on manufacturing properties are recorded as cost of products sold in the period in which they are incurred.

Where a tangible fixed asset comprises major components having different useful lives, these components are accounted for as separate items. Spare parts are included in property, plant and equipment.

Depreciation method is reviewed at each year end. Depreciation is calculated using the straight-line method to amortize the cost of each asset to its residual value over its estimated useful life as follows:

Land	No depreciation
Buildings and improvements	10-50 years
Production equipment	5-40 years
Vehicles, furniture and fixtures and other equipment	3-20 years

Property, plant and equipment used in mining activities are depreciated over its useful life or over the remaining life of the mine if shorter and there is no alternative use possible.

The assets' useful lives are reviewed, and adjusted if appropriate, at each year end. The re-estimation of assets useful lives by the Company did not materially affect depreciation charges in 2021, 2020 and 2019.

Gains and losses on disposals are determined by comparing the proceeds with the corresponding carrying amounts and are included in the income statement.

If the carrying amount of an asset were greater than its estimated recoverable amount, it would be written down to its recoverable amount (see Note 3 (f) "Impairment").

Amortization charges are included in cost of sales, selling, general and administrative expenses.

3.    ACCOUNTING POLICIES (continued)

(2) Right-of-use assets

The Company is a party to lease contracts for:

–Land

–Plants and equipment for the production of industrial gases and other production materials.

–Transportation and maintenance equipment.

–Warehouses and office spaces.

These leases are recognized, measured and presented in accordance to IFRS 16 “Leases”, following the guidelines described below.

Accounting by the lessee

The Company recognizes a right-of-use asset and a lease liability at the commencement date of each lease contract that grants the right to control the use of an identified asset during a period of time. The commencement date is the date in which the lessor makes an underlying asset available for use by the lessee.

The Company applied exemptions for leases with a duration lower than 12 months, with a value lower than thirty thousand dollars and/or with clauses related to variable payments. These leases have been considered as short-term leases and, accordingly, no right-of-use asset or lease liability have been recognized.

At initial recognition, the right-of-use asset is measured considering:

– The value of the initial measurement of the lease liability;

– Any lease payments made at or before the commencement date, less any lease incentives; and

– Any initial direct costs incurred by the lessee.

After initial recognition, the right-of-use assets are measured at cost, less any accumulated depreciation and/or impairment losses, and adjusted for any re-measurement of the lease liability.

Depreciation of the right-of-use asset is calculated using the straight-line method over the estimated duration of the lease contract, as follows:

Buildings and facilities        1-28 years

Machinery            1-11 years

If the lease transfers ownership of the underlying asset to the Company by the end of the lease term, or if the cost of the right-of-use asset reflects that the Company will exercise a purchase option, the Company depreciates the right-of-use asset from the commencement date to the end of the useful life of the underlying asset. Otherwise, the Company depreciates the right-of-use asset from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term.

Accounting by the lessor

When the Company is acting as a lessor, each of its leases is classified as either operating or finance lease:

– Leases where a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases.

– Leases where all substantial risks and rewards of ownership are transferred by the lessor to the lessee are classified as finance leases.

Intangible assets

Information system projects

Generally, costs associated with developing or maintaining computer software programs are recognized as an expense as incurred. However, costs directly related to the acquisition and implementation of information systems are recognized as intangible assets if they have a probable economic benefit exceeding the cost beyond one year and comply with the recognition criteria of IAS 38.

Information system projects recognized as assets are amortized using the straight-line method over their useful lives, not exceeding a period of 3 years. Amortization charges are included in cost of sales, selling, general and administrative expenses.

(2)    Mining assets

Mining assets include:

(a)Mining licenses acquired;

(b)Capitalized exploration and evaluation costs, reclassified from exploration and evaluation costs (see note 3 (e) 3); and

(c)Capitalized developmental stripping costs (see note 3 (u)).

Mining licenses were recognized as separate intangible assets upon the acquisition of the investment in Mexico and comprise the right to exploit the mines and are recognized at its fair value at acquisition date less accumulated amortization.

These mining concessions were granted for a 50-year period; following the expiration of the initial concession term, the concessions are renewable for an additional 50-year term in accordance with, and subject to the procedures set forth in, applicable Mexican mining law.

Amortization charge is calculated by using the unit-of-production method, on the basis of actual mineral extracted in each period compared to the estimated mineral reserves, and is included in cost of sales. Any change in the estimation of reserves is accounted for prospectively. The resulting amortization rate for the years ended December 31, 2021, 2020 and 2019, is approximately 7%, 4% and 5% per year, respectively.

3.    ACCOUNTING POLICIES (continued)

(3)Exploration and evaluation costs

Exploration and evaluation activities involve the search for iron ore resources, the determination of technical feasibility and the assessment of commercial viability of an identified resource.

Exploration and evaluation costs are measured at cost. Costs directly associated with exploration and evaluation activities are capitalized as intangible assets until the determination of reserves is evaluated. The costs associated to the acquisition of machinery and equipment are recognized as property, plant and equipment. If it is determined that commercial discovery has been achieved, costs incurred are reclassified into Mining assets and amortization starts once production begins.

Exploration costs are tested for impairment annually or whenever there are indicators that impairment exists. Indicators of impairment include, but are not limited to:

–Rights to explore in an area have expired or will expire in the near future without renewal;

–No further exploration and evaluation is planned or budgeted;

–A decision to discontinue exploration and evaluation in an area because of the absence of commercial reserves; and

–Sufficient data exists to indicate that the book value will not be fully recovered from future development and production.

When analyzing the existence of impairment indicators, the exploration and evaluation areas from the mining units will be evaluated.

(4)    Goodwill

Goodwill represents the excess of the acquisition cost over the fair value of Ternium's participation in acquired companies' net assets at the acquisition date. Under IFRS 3, goodwill is considered to have an indefinite life and not amortized, but is subject to annual impairment testing.

Goodwill is allocated to Cash-generating units ("CGU") for the purpose of impairment testing. The allocation is made to those cash-generating units expected to benefit from the business combination which generated the goodwill being tested. The impairment losses on goodwill cannot be reversed.

As of December 31, 2021 and 2020, the carrying amount of goodwill allocated to the Mexico CGU was $662.3 million, of which $619.8 million corresponds to steel operations and $42.5 million to mining operations.

(5)    Research and development

Research expenditures are recognized as expenses as incurred. Development costs are recorded as cost of sales in the income statement as incurred because they do not fulfill the criteria for capitalization. Research and development expenditures for the years ended December 31, 2021, 2020 and 2019 totaled $9.8 million, $8.3 million and $10.0 million, respectively.

3.    ACCOUNTING POLICIES (continued)

(6)    Customer relationships acquired in a business combination

In accordance with IFRS 3 and IAS 38, Ternium has recognized the value of customer relationships in connection with the acquisition of Ternium Staal B.V. as of September 7, 2017. The value of the slab commitment agreement by which Ternium Investments S.à r.l. was entitled to invoice, under certain conditions, the price difference between slabs and hot rolled coils has been amortized using the units of slabs sold method. As of December 31, 2021, the asset related to this slab commitment agreement was fully amortized.

(7)    Trademarks acquired in a business combination

Trademarks are amortized using the straight-line method over a useful life of between 5 to 10 years.

Impairment

Assets that have an indefinite useful life (including goodwill) are not subject to amortization and are tested annually for impairment or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets that are subject to amortization and investments in affiliates are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less cost to sell and the value in use.

To carry out these tests, assets are grouped at the lowest levels for which there are separately identifiable cash flows (each, a CGU). When evaluating long-lived assets for potential impairment, the Company estimates the recoverable amount based on the value in use of the corresponding CGU. The value in use of each CGU is determined on the basis of the present value of net future cash flows which will be generated by the assets tested.

Determining the present value of future cash flows involves highly sensitive estimates and assumptions specific to the nature of each CGU's activities, including estimates and assumptions relating to amount and timing of projected future cash flows, expected changes in market prices, expected changes in the demand of Ternium products and services, selected discount rate and selected tax rate.

Ternium uses, for the steel segment impairment tests, cash flow projections for the next five years based on past performance and expectations of market development; thereafter, it uses a perpetuity rate. In the case of CGU Mexico, cash flow projections are prepared until the mines are fully depleted and are based on past performance and expectations of market development; then a perpetuity rate starts. The growth rate used for the perpetuity rate is of 2.3%. Application of the discounted cash flow (DCF) method to determine the value in use of a CGU begins with a forecast of all expected future net cash flows. Variables considered in forecasts include the gross domestic product (GDP) growth rates of the country under study and their correlation with steel demand, level of steel prices and estimated raw material costs as observed in industry reports.

3.    ACCOUNTING POLICIES (continued)

Cash flows are discounted at rates that reflect specific country and currency risks associated with the cash flow projections. The discount rates used are based on the weighted average cost of capital (WACC), which is considered to be a good indicator of cost of capital. As of December 31, 2021 the discount rate used to test goodwill allocated to the Steel and Mining Mexico CGU for impairment was 9.93% (as of December 31, 2020, 8.87%).

As a result of the above factors, actual cash flows and values could vary significantly from the forecasted future cash flows and related values derived using discounting techniques. Based on the information currently available, however, Ternium believes that it is not reasonably possible that the variation would cause the carrying amount to exceed the recoverable amount of the CGUs.

Considering the economic situation in Argentina, the increase in the inflation rates, the devaluation of the Argentine peso and a weaker industrial environment as of June 30, 2020, the Company decided to assess the recoverability of its investments in Argentina, resulting in no impairment charges to be recognized. As of June 30, 2020, the discount rate used to test the investment in Argentine subsidiaries for impairment was 14.3%. Also, considering the economic situation in Brazil as of June 30, 2020, the Company decided to assess the recoverability of its investments in Brazil, resulting in no impairment charges to be recognized. As of June 30, 2020, the discount rate used to test the investment in the Brazilian subsidiary for impairment was 10.3%. As of December 31, 2021 and 2020, no new impairment triggers were detected in these CGUs and, consequently, no impairment tests were prepared.

In connection with investments in non-consolidated companies and considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company decided to assess the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. As of December 31, 2021, the discount rate used to test the investment in Usiminas for impairment was 11.95%.

During the years 2021, 2020 and 2019, no impairment provisions were recorded in connection with assets that have an indefinite useful life (including goodwill).

Other investments

Other investments consist primarily of investments in financial debt instruments and equity investments where the Company holds a minor equity interest and does not exert significant influence.

All purchases and sales of investments are recognized on the settlement date, which is not significantly different from the trade date, which is the date that Ternium commits to purchase or sell the investment.

Income from financial instruments at fair value through profit or loss is recognized in Other financial income (expenses), net in the consolidated income statement. The fair value of quoted investments is based on current bid prices. If the market for a financial investment is not active or the securities are not listed, the Company estimates the fair value by using standard valuation techniques. Dividends from investments in equity instruments are recognized in the income statement when the Company's right to receive payments is established.

Certain fixed income financial instruments purchased by the Company have been categorized as at fair value through other comprehensive income. The results of these financial investments are recognized in Finance Income in the Consolidated Income Statement using the effective interest method. Unrealized gains and losses other than impairment and foreign exchange results are recognized in Other comprehensive income. On maturity or disposal, net gain and losses previously deferred in Other comprehensive income are recognized in Finance Income in the Consolidated Income Statement.

Inventories

Inventories are stated at the lower of cost (calculated using the first-in-first-out "FIFO" method) or net realizable value. The cost of finished goods and goods in process comprises raw materials, direct labor, depreciation, other direct costs and related production overhead costs. It excludes borrowing costs. Goods acquired in transit at year end are valued at supplier's invoice cost.

The cost of iron ore produced in our mines comprises all direct costs necessary to extract and convert stockpiled inventories into raw materials, including production stripping costs, depreciation of fixed assets related to the mining activity and amortization of mining assets for those mines under production.

The Company assesses the recoverability of its inventories considering their selling prices, if the inventories are damaged, or if they have become wholly or partially obsolete (see note 3 (bb) (4)).

Trade receivables and other receivables

Trade and other receivables are recognized initially at fair value, generally the original invoice amount. The Company applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables are grouped based on shared credit risk characteristics and the days past due. The Company keeps an allowance for trade receivables, recorded in an asset account to offset the trade receivables in an amount estimated sufficient to cover the losses resulting from the impossibility for the debtors to cancel the amounts owed. This allowance for trade receivables is recorded with a charge to selling expenses.

Cash and cash equivalents

Cash and cash equivalents and highly liquid short-term securities are carried at fair market value or at a historical cost which approximates fair market value.

For purposes of the cash flow statement, cash and cash equivalents comprise cash, bank current accounts and short-term highly liquid investments (original maturity of three months or less at date of acquisition) and overdrafts.

In the consolidated statement of financial position, bank overdrafts are included in borrowings within current liabilities.

Assets (disposal groups) classified as held for sale

Assets (disposal groups) are classified as assets held for sale, complying with the recognition criteria of IFRS 5, and stated at the lower of carrying amount and fair value less cost to sell if their carrying amount is recovered principally through a sale transaction rather than through continuing use.

The carrying value of assets classified as held for sale, at December 31, 2021 and 2020 totals $1.9 million and $5.0 million, respectively, which corresponds principally to land and other real estate items. Sale is expected to be completed within a one-year period.

Borrowings

Borrowings are recognized initially for an amount equal to the net proceeds received. In subsequent periods, borrowings are stated at amortized cost following the effective interest method

Lease liabilities

The lease liability is initially measured at the present value of the lease payments that are not paid at such date, including the following concepts:

– Fixed payments, less any lease incentives receivable;

– Variable lease payments that depend on an index or rate, initially measured using the index or rate as of the commencement date;

– Amounts expected to be payable by the lessee under residual value guarantees;

– The exercise price of a purchase option if the lessee is reasonably certain to exercise that option; and

– Payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

Variable lease liabilities with payments dependent on external factors, such as minimum volumes sold or used, are not included in the initial measurement of the lease liabilities and such payments are recognized directly in profit and loss.

Lease payments are discounted using incremental borrowing rates for the location and currency of each lease contract or, if available, the rate implicit in the lease contract.

The finance cost is charged to profit or loss over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

The lease term determined by the Company comprises:

– Non-cancelable period of lease contracts;

– Periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and

– Periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option.

After the commencement date, the Company measures the lease liability by:

– Increasing the carrying amount to reflect interest on the lease liability;

– Reducing the carrying amount to reflect lease payments made; and

– Re-measuring the carrying amount to reflect any reassessment or lease modifications.

Income taxes - current and deferred

The current income tax charge is calculated on the basis of the tax laws in force in the countries in which Ternium and its subsidiaries operate. Management evaluates positions taken in tax returns with respect to situations in which applicable tax regulation could be subject to interpretation. A liability is recorded for tax benefits that were taken in the applicable tax return but have not been recognized for financial reporting.

3.    ACCOUNTING POLICIES (continued)

Deferred income taxes are calculated using the liability method on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting, nor taxable profit or loss. The principal temporary differences arise on fixed assets, intangible assets, inventories valuation and provisions for pensions. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantially enacted at year end. Under IFRS, deferred income tax assets (liabilities) are classified as non-current assets (liabilities).

Deferred tax assets are recognized to the extent it is probable that future taxable income will be available to offset temporary differences.

Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associated companies, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.

Deferred tax assets and liabilities are re-estimated if tax rates change. These amounts are charged or credited to the consolidated income statement or to the item “Other comprehensive income for the year” in the consolidated statement of comprehensive income, depending on the account to which the original amount was charged or credited.

Employee liabilities

Post-employment obligations

The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually (at year end) by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. In countries where there is no deep market in such bonds, the market rates on government bonds are used.

Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise. Past-service costs are recognized immediately in income.

For defined benefit plans, net defined benefit liability/asset is calculated based on the surplus or deficit derived by the difference between the defined benefit obligations less plan assets.

3.    ACCOUNTING POLICIES (continued)

For defined contribution plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

Mexico

Ternium Mexico has defined benefit and defined contribution plans.

The valuation of the liabilities for the defined benefit employee retirement plans (pensions and seniority premiums) covers all employees and is based primarily on their years of service, their present age and their remuneration at the date of retirement. The cost of the employee retirement plans (pension, health-care expenses and seniority premiums) is recognized as an expense in the year in which services are rendered in accordance with actuarial studies made by independent actuaries. The formal retirement plans are congruent with and complementary to the retirement benefits established by the Mexican Institute of Social Security. Additionally, the Company has established a plan to cover health-care expenses of retired employees. The Company has established a commitment for the payment of pensions and seniority premiums, as well as for health-care expenses.

The defined contribution plans provide a benefit equivalent to the capital accumulated with the company's contributions, which are provided as a match of employees' contributions to the plan. The plan provides vested rights according to the years of service and the cause of retirement.

Argentina

Ternium Argentina implemented an unfunded defined benefit employee retirement plan for certain senior officers. The plan is designed to provide certain benefits to those officers (additional to those contemplated under applicable Argentine labor laws) in case of termination of the employment relationship due to certain specified events, including retirement. This unfunded plan provides defined benefits based on years of service and final average salary.

(2)Termination benefits

Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits when it is demonstrably committed to either: (i) terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal or (ii) providing termination benefits as a result of an offer made to encourage voluntary redundancy.

(3)    Other compensation obligations

Employee entitlements to annual leave and long-service leave are accrued as earned.

3.    ACCOUNTING POLICIES (continued)

During 2007, Ternium launched an incentive retention program (the "Program") applicable to certain senior officers and employees of the Company, who will be granted a number of Units throughout the duration of the Program. The value of each of these Units is based on Ternium's shareholders' equity (excluding non-controlling interest). Also, the beneficiaries of the Program are entitled to receive cash amounts based on (i) the amount of dividend payments made by Ternium to its shareholders, and (ii) the number of Units held by each beneficiary to the Program. Units vest ratably over a period of four years and will be redeemed by the Company ten years after grant date, with the option of an early redemption at seven years after grant date. From 2018 units were vest ratably over the same period and will be mandatorily redeemed by the Company seven years after grant date. As the cash payment of the benefit is tied to the book value of the shares, and not to their market value, Ternium valued this long-term incentive program as a long term benefit plan as classified in IAS 19.

As of December 31, 2021 and 2020, the outstanding liability corresponding to the Program amounts to $67.7 million and $43.4 million, respectively. The total value of the units granted to date under the program, considering the number of units and the book value per share as of December 31, 2021 and 2020, is $72.1 million and $43.3 million, respectively.

Under Mexican law, Ternium's subsidiaries are required to pay their employees an annual benefit which is determined as a percentage of taxable profit for the year.

(4)    Social security contributions

Social security laws in force in the countries in which the Company operates provide for pension benefits to be paid to retired employees from government pension plans and/or private fund managed plans to which employees may elect to contribute. As stipulated by the respective laws, Ternium Argentina and Ternium Mexico make monthly contributions calculated based on each employee's salary to fund such plans. The related amounts are expensed as incurred. No additional liabilities exist once the contributions are paid.

Provisions

Ternium has certain contingencies with respect to existing or potential claims, lawsuits and other proceedings. Unless otherwise specified, Ternium accrues a provision for a present legal or constructive obligation as a result of a past event, when it is probable that future cost could be incurred and that cost can be reasonably estimated. Generally, accruals are based on developments to date, Ternium's estimates of the outcomes of these matters and the advice of Ternium's legal advisors.

Trade payables

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.

Revenue recognition and other income

Revenue is recognized at a point of time from sales to direct customers upon the satisfaction of performance obligations, which occurs when control of the goods transfers to the customer and the customer obtains the benefits from the goods, the potential cash flows and the transaction price can be measured reliably, and it is probable that the Company will collect the consideration in connection with the exchange of the goods. The control over the goods is obtained by the customer depending on when the goods are made available to the shipper or the customer takes possession of the goods, depending on the delivery terms. The Company considers that it has completed its performance obligations when the goods are delivered to its customers or to a shipper who will transport the goods to its customers. The revenue recognized by the Company is measured at the transaction price of the consideration received or receivable to which the Company is entitled to, reduced by estimated returns and other customer credits, such as discounts and volume rebates, based on the expected value to be realized and after eliminating sales within the group.

Interest income is recognized on an effective yield basis.

Borrowing Costs

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

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

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

Cost of sales, selling, general and administrative expenses

Cost of sales and expenses are recognized in the income statement on the accrual basis of accounting.

Commissions, freight and other selling expenses, including shipping and handling costs, are recorded in Selling, general and administrative expenses in the Consolidated Income Statement.

Stripping costs

Stripping costs are the costs associated with the removal of overburden and other waste materials and can be incurred before the mining production commences (“development stripping”) or during the production stage (“production stripping”).

3.    ACCOUNTING POLICIES (continued)

Development stripping costs that contribute to the future economic benefits of mining operations are capitalized as intangible assets (Mining assets). Production stripping costs which are part of on-going activities are included in the cost of the inventory produced (that is extracted) at each mine during the period in which they are incurred.

Capitalization of development stripping costs finishes when the commercial production of the mine commences. At that time, all development stripping costs are presented within Mining assets and depreciated on a unit-of-production basis. It is considered that commercial production begins when the production stage of mining operations begins and continues throughout the life of a mine.

Mining development costs

Mining development costs are the costs associated to the activities related to the establishment of access to the mineral reserve and other preparations for commercial production. These activities often continue during production.

Development expenditures are capitalized and classified as Work in progress. On completion of development, all assets included in Work in progress are individually reclassified to the appropriate category of property, plant and equipment and depreciated accordingly.

Asset retirement obligations

Ternium records asset retirement obligations (“ARO”) initially at the fair value of the legal or constructive obligation in the period in which it is incurred and capitalizes the ARO by increasing the carrying amount of property, plant and equipment. The fair value of the obligation is determined as the discounted value of the expected future cash flows and is included in Provisions. The liability is accreted to its present value through net financing cost and the capitalized cost is depreciated based in the unit of production method.

Earnings per share

Earnings per share are calculated by dividing the net income attributable to shareholders by the daily weighted average number of ordinary shares issued during the year, excluding the average number of shares of the parent Company held by the Group. There are no dilutive securities for the periods presented.

Derivative financial instruments and hedging activities

Ternium designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction. These transactions are classified as cash flow hedges (mainly interest rate swaps, collars, currency forward contracts on highly probable forecast transactions and commodities contracts). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in OCI. Amounts accumulated in OCI are recognized in the income statement in the same period as any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Ternium derivative financial instruments (asset or liability) continues to be reflected in the statement of financial position.

3.    ACCOUNTING POLICIES (continued)

For transactions designated and qualifying for hedge accounting, Ternium documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. At December 31, 2021 and 2020, the effective portion of designated cash flow hedges (net of taxes) amounted to $(0.04) million and $(0.23) million, respectively, and were included under "changes in the fair value of derivatives classified as cash flow hedges" line item in the statement of comprehensive income (see Note 26 (a)).

More information about accounting for derivative financial instruments and hedging activities is included in Note 28 "Financial risk management".

Treasury shares

Acquisitions of treasury shares are recorded at acquisition cost, deducted from equity until disposal. The gains and losses on disposal of treasury shares are recognized under "Reserves" in the consolidated statement of financial position.

Cash flow

The consolidated statements of cash flows have been prepared using the indirect method and contain the use of the following expressions and their respective meanings:

a)    Operating activities: activities that constitute ordinary Group revenues, as well as other activities that cannot be qualified as investing or financing.

b)    Investing activities: acquisition, sale or disposal by other means of assets in the long-term and other investments not included in cash and cash equivalents.

c)    Financing activities: activities that generate changes in the size and composition of net equity and liabilities that do not form part of operating activities.

Critical accounting estimates

The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities. Estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Management makes estimates and assumptions concerning the future. Actual results may differ significantly from these estimates under different assumptions or conditions.

The principal estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

(1) Goodwill impairment test

Assessment of the recoverability of the carrying value of goodwill requires significant judgment. Management evaluates goodwill allocated to the operating units for impairment on an annual basis or whenever there is an impairment indicator.

3.    ACCOUNTING POLICIES (continued)

Goodwill is tested at the level of the CGUs. Impairment testing of the CGUs is carried out and the value in use determined in accordance with the accounting policy stated in Note 3(f). The discount rates used for these tests are based on Ternium's weighted average cost of capital adjusted for specific country and currency risks associated with the cash flow projections. The discount rate used at December 31, 2021 was 9.93% and no impairment charge resulted from the impairment test performed. See notes 3(f) and 3(e)(4).

(2)Income taxes

Management calculates current and deferred income taxes according to the tax laws applicable to each subsidiary in the countries in which such subsidiaries operate. However, due to uncertain tax positions, certain adjustments necessary to determine the income tax provision are finalized only after the balance sheet is issued. In cases in which the final tax outcome is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Also, when assessing the recoverability of tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies.

(3)    Loss contingencies

Ternium is subject to various claims, lawsuits and other legal proceedings that arise in the ordinary course of business, including customer claims in which a third party is seeking reimbursement or indemnity. The Company's liability with respect to such claims, uncertain tax positions, lawsuits and other legal proceedings cannot be estimated with certainty. Periodically, management reviews the status of each significant matter and assesses potential financial exposure. If the potential loss from the claim or proceeding is considered probable and the amount can be reasonably estimated, a liability is recorded. Management estimates the amount of such liability based on the information available and the assumptions and methods it has concluded are appropriate, in accordance with the provisions of IFRS. Accruals for such contingencies reflect a reasonable estimate of the losses to be incurred based on information available, including the relevant litigation or settlement strategy, as of the date of preparation of these financial statements. As additional information becomes available, management will reassess its evaluation of the pending claims, lawsuits and other proceedings and revise its estimates. The loss contingencies provision amounts to $83.3 million and $80.6 million as of December 31, 2021 and 2020, respectively,.

(4)Allowance for obsolescence of supplies and spare parts and slow-moving inventory

Management assesses the recoverability of its inventories considering their selling prices or whether they are damaged or have become wholly or partly obsolete.

Net realizable value is the estimated selling price in the ordinary course of business, less the costs of completion and selling expenses.

The Company establishes an allowance for obsolete or slow-moving inventory in connection with finished goods and goods in process. The allowance for slow-moving inventory is recognized for finished goods and goods in process based on management's analysis of their aging. In connection with supplies and spare parts, the calculation is based on management's analysis of their aging, the capacity of such materials to be used based on their levels of preservation and maintenance, and their potential obsolescence due to technological change.

3.    ACCOUNTING POLICIES (continued)

As of December 31, 2021 and 2020, the Company recorded no allowance for net realizable value and $61.5 million and $58.6 million, respectively, as allowance for obsolescence.

(5)Useful lives and Impairment of Property, Plant and Equipment and Other Long-lived Assets

In determining useful lives, management considered, among others, the following factors: age, operating condition and level of usage and maintenance. Management conducted visual inspections for the purpose of (i) determining whether the current conditions of such assets are consistent with normal conditions of assets of similar age; (ii) confirming that the operating conditions and levels of usage of such assets are adequate and consistent with their design; (iii) establishing obsolescence levels and (iv) estimating life expectancy, all of which were used in determining useful lives. Management believes, however, that it is possible that the periods of economic utilization of property, plant and equipment may be different than the useful lives so determined. Furthermore, management believes that this accounting policy involves a critical accounting estimate because it is subject to change from period to period as a result of variations in economic conditions and business performance.

When assessing whether an impairment indicator may exist, the Company evaluates both internal and external sources of information, such as the following:

–whether significant changes with an adverse effect on the entity have taken place during the period, or will take place in the near future, in the technological, market, economic or legal environment in which the entity operates or in the market to which an asset is dedicated;

–whether market interest rates or other market rates of return on investments have increased during the period, and those increases are likely to affect the discount rate used in calculating an asset's value in use and decrease the asset's recoverable amount materially;

–whether the carrying amount of the net assets of the entity is more than its market capitalization;

–whether evidence is available of obsolescence or physical damage of an asset.

–whether significant changes with an adverse effect on the entity have taken place during the period, or are expected to take place in the near future, in the extent to which, or manner in which, an asset is used or is expected to be used. These changes include the asset becoming idle, plans to discontinue or restructure the operation to which an asset belongs, plans to dispose of an asset before the previously expected date, and reassessing the useful life of an asset as finite rather than indefinite; and

–whether evidence is available from internal reporting that indicates that the economic performance of an asset is, or will be, worse than expected.

Considering the economic situation in Argentina as of December 31, 2019, and as of June 30, 2020, the Company tested the recoverability of its investment in Ternium Argentina as of such dates, resulting in no impairment charges to be recognized. As of December 31, 2021 and 2020, no new impairment triggers were detected and, consequently, no impairment test was prepared.

The Company also tested the recoverability of its investments in the rest of the subsidiaries as of June 30, 2020, due to the pandemic, resulting in no impairment charges to be recognized. Considering that no new impairment indicators were identified in the rest of subsidiaries as of December 31, 2021 and 2020, the Company additionally tested the value of the goodwill for impairment, resulting in no impairment charges to be recognized.

In connection with investments in non-consolidated companies and considering that the market value of Usiminas was slightly below the book value as of December 31, 2021, the Company decided to assess the recoverability of its investment in Usiminas as of such date, resulting in no impairment charges to be recognized. As of December 31, 2021, the discount rate used to test the investment in Usiminas for impairment was 11.95%.

3.    ACCOUNTING POLICIES (continued)

(6)    Mining reserve estimates

Reserves are estimates of the amount of product that can be economically and legally extracted from the Company’s mining concessions. In order to estimate reserves, a range of geological, technical and economic factors is required to be considered. Estimating the quantity and/or grade of reserves requires complex and difficult geological judgments to interpret the data. Because the economic assumptions used to estimate reserves change from period to period, and because additional geological data is generated during the course of operations, estimates of reserves may change from period to period.

Changes in reported reserves may affect the Company’s financial results and financial position, including the following:

–Asset carrying amounts may be affected due to changes in estimated future cash flows.

–Depreciation and amortization charges may change where such charges are determined by the units of production basis, or where the useful economic lives of assets change.

–Stripping costs recognized in Mining assets or charged to results may change due to changes in stripping ratios or the units of production basis of depreciation.

–Asset retirement obligations may change where changes in estimated reserves affect expectations about the timing or cost of these activities.

(7)    Post-employment obligation estimates

The Company estimates at each year-end the provision necessary to meet its post-employment obligations in accordance with the advice from independent actuaries. The calculation of post-employment and other employee obligations requires the application of various assumptions. The main assumptions for post-employment and other employee obligations include discount rates, compensation growth rates, pension growth rates and life expectancy.  Changes in the assumptions could give rise to adjustments in the results and liabilities recorded and might have an impact on the post-employment and other employee obligations recognized in the future.

(8)    Valuation of lease liabilities and right-of-use assets

The application of IFRS 16 requires the Company to make judgments that affect the recognition and valuation of the lease liabilities and the right-of-use assets, including the determination of the contracts within the scope of the Standard, the contract term and the interest rate used for the discount of future cash flows.

The lease term determined by the Company generally comprises non-cancellable period of leases contracts, periods covered by an option to extend the lease if the Company is reasonably certain to exercise that option and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option. The same term is applied as economic useful life of right-of-use assets.

3.    ACCOUNTING POLICIES (continued)

The present value of the lease payments is determined using the discount rate representing a risk-free interest rate, adjusted by a spread related to the credit quality of the Company in each location and currency rate in connection with each lease contract.

(9) Change in the functional currency of argentine subsidiaries

The determination of the functional currency requires management to make significant judgments. Ternium Argentina has performed a review of its functional currency and concluded that the currency that most faithfully represents the economics effects of the entity is the U.S. dollar and therefore its functional currency has changed from the local currency to the U.S. dollar. This change was prospective from January 1, 2020, and did not affect the balances at December 31, 2019, nor results or cash flows for the year then ended.

It was based on the following considerations:

–In the last two years, the exchange rate of the Argentine peso has been severely affected by devaluations against the U.S. dollar and Argentina continues to be a highly inflationary economy. These events had very limited impact on sale's price in U.S. dollar;

–In this context, there is also a greater proportion of total production cost in U.S. dollar;

–Furthermore, new global trade restrictions, affecting the international trade of steel along with limited restrictions of imports in Argentina, have led to a greater correlation of local prices to global prices.

–Factors to determine the functional currency were always mixed. However, currently most of revenue and costs of production are negotiated and priced in U.S. dollar.

The change in functional currency of Ternium Argentina significantly reduced the volatility of the Company’s earnings that was due to foreign exchange movements and the application of IAS 29 - Financial Reporting in Hyperinflationary Economies.

Application of IAS 29 in financial reporting of Argentine subsidiaries and associates

Application of IAS 29 in financial reporting of Argentine subsidiaries and associates

For the years ended December 31, 2019 and 2018, the Company applied IAS 29 “Financial Reporting in Hyperinflationary Economies”, which requires that the financial statements of entities whose functional currency is that of a hyperinflationary economy to be adjusted for the effects of changes in a suitable general price index and to be expressed in terms of the current unit of measurement at the closing date of the reporting period. Accordingly, the inflation produced from the date of acquisition or from the revaluation date, as applicable, must be computed in the non-monetary items.

In order to conclude on whether an economy is categorized as hyperinflationary under the terms of IAS 29, the Standard details a series of factors to be considered, including the existence of a cumulative inflation rate in three years that approximates or exceeds 100%.

Considering that the significant increase in inflation during 2018, which exceeded the 100% three-year cumulative inflation rate, and that the rest of the indicators did not contradict the conclusion that Argentina should be considered a hyperinflationary economy for accounting purposes, the Company considered that there was sufficient evidence to conclude that Argentina was a hyperinflationary economy under the terms of IAS 29 as from July 1, 2018, and, accordingly, applied IAS 29 as from that date in the financial reporting of its subsidiaries and associates with the Argentine peso as functional currency.

3.    ACCOUNTING POLICIES (continued)

According to this principle, the financial statements of an entity that reports in the currency of a hyperinflationary economy should be stated in terms of the measuring unit current on the date of the financial statements. All statement of financial position amounts that are not stated in terms of the measuring unit current on the date of the financial statements must be restated by applying a general price index. All income statement components must be stated in terms of the measuring unit current on the date of the financial statements, applying the change in the general price index that occurred since the date when revenues and expenses were originally recognized in the financial statements.

The inflation adjustment on the initial balances was calculated by means of conversion factor derived from the Argentine price indexes published by the National Institute of Statistics (“INDEC”). The price index for the year periods ended December 31, 2019 and 2018, were 1.54 and 1.48, respectively.

The main procedures for the above-mentioned adjustment are as follows:

–Monetary assets and liabilities which are carried at amounts current at the balance sheet date are not restated because they are already expressed in terms of the monetary unit current at the balance sheet date.

–Non-monetary assets and liabilities which are not carried at amounts current at the balance sheet date, and components of shareholders' equity are adjusted by applying the relevant conversion factors.

–All items in the income statement are restated by applying the relevant conversion factors.

–The effect of inflation on the Company’s net monetary position is included in the income statement, in Other financial income (expenses), net, under the caption “Inflation adjustment results”.

–The ongoing application of the re-translation of comparative amounts to closing exchanges rates under IAS 21 and the hyperinflation adjustments required by IAS 29 will lead to a difference in addition to the difference arising on the adoption of hyperinflation accounting.

The comparative figures in these consolidated financial statements presented in a stable currency are not adjusted for subsequent changes in the price level or exchange rates. This resulted in an initial difference, arising on the adoption of hyperinflation accounting, between the closing equity of the previous year and the opening equity of the current year. The Company recognized this initial difference directly in equity.

Climate Change

Climate Change

Ternium is committed to the UN Global Compact Initiative, its sustainable development goals, and the world's efforts to address Climate Change.

The Company is determined to find ways to reduce the carbon footprint of its operations and the steel value chain. In February 2021, Ternium announced a medium-term target to reduce its carbon dioxide emissions intensity rate by 20% in 2030, compared to its 2018 base rate of 1.7 tons of carbon dioxide per ton of steel. The Company’s strategy to achieve this 2030 reduction target consists of a multi-faceted approach that includes increasing the use of renewable energy and the development of energy efficiency strategies, increasing the participation of scrap in the metallic mix, improving the carbon capture capacity at its DRI facilities, replacing coking coal with charcoal and prioritizing lower specific-emission steelmaking technologies.

The Company intends to continue analyzing and developing measures to decarbonize its operations over the longer term. This endeavor will require significant long-term investments, conditioned by technology innovation, cooperation within the value chain, government regulations, and capital availability for decarbonization projects. Factors like access to abundant and affordable clean energy, appropriate energy infrastructure, local and global regulation that guarantee fair trade and carbon capture storage, access to sustainable finance for low emissions steel-making technologies, and changes in consumer behavior will be key in the development of solutions and the outcomes in the next decades.

Given that Ternium’s climate-change-related decarbonization plans span over many years and are subject to significant uncertainty as described above, they have not been included as part of the assumptions used to calculate future cash flows of the recoverable amount of the company’s CGUs. Estimates and assumptions related to the impairment test over long-lived assets and goodwill, useful lives of assets, capital and research and development expenditures, inventory valuation, recovery of deferred tax assets and provisions, and contingent liabilities are based on available information and government regulations in place as of December 31, 2021, as well as on the company’s current short-term investment plans.

Recently issued accounting pronouncements

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

The following amendments, standards and interpretations have been applied on the year starting January 1, 2021:

International Financial Reporting Standard 7, “Financial Instruments: Disclosures”, International Financial Accounting Standard 9, “Financial Instruments” and International Accounting Standard 39, “Financial Instruments: Recognition and Measurement” - Interest Rate Benchmark Reform

The IASB has issued amendments to IFRS 7 “Financial Instruments: Disclosures”, IFRS 9 “Financial Instruments” and IAS 39 “Financial Instruments: Recognition and Measurement” which provide certain reliefs in relation to interest rate benchmark reforms. The reliefs relate to hedge accounting and have the effect that the reforms should not generally cause hedge accounting to terminate. However, any hedge ineffectiveness should continue to be recorded in the income statement.

The Company's management has assessed the effects of applying these amendments on the Company’s financial statements and has not identified any material impact in the application of these amendments.

International Financial Reporting Standard 16, “Leases” – Amendments on Covid-19-related Rent Concessions

In May 2020, the IASB made an amendment to IFRS 16 “Leases” in the context of the COVID-19 pandemic and its impact on rent concessions granted to lessees. Such concessions might take a variety of forms, including payment holidays and deferral of lease payments, which provides lessees with an option to treat qualifying rent concessions in the same way as they would if they were not lease modifications. In many cases, this will result in accounting for the concessions as variable lease payments in the period in which they are granted. Entities applying the practical expedients must disclose this fact, whether the expedient has been applied to all qualifying rent concessions or, if not, information about the nature of the contracts to which it has been applied, as well as the amount recognized in profit or loss arising from the rent concessions.

The Company's management has assessed the effects of applying this amendment on the Company’s financial statements and has not identified any lease agreements which may be impacted by the application of this amendment.

The following standards, amendments to standards and interpretations are not mandatory for the financial year beginning January 1, 2021, and have not been early adopted:

International Accounting Standard 12, “Income taxes” - Amendments

The IASB has issued amendments to IAS 12 “Income taxes”, which introduce a further exception from the initial recognition exemption. Under the amendments, an entity does not apply the initial recognition exemption for transactions that give rise to equal taxable and deductible temporary differences. Depending on the applicable tax law, equal taxable and deductible temporary differences may arise on initial recognition of an asset and liability in a transaction that is not a business combination and affects neither accounting nor taxable profit.

The Company's management has assessed the effects of applying these amendments on the Company’s financial statements and has not identified any material impact in the application of these amendments.

27.    RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (continued)

By application of this method, Ternium recognizes gains and losses on deferred income tax due to the effect of the change in the value on the tax basis in subsidiaries, which have a functional currency different to their local currency, mainly Mexico and Argentina.
