The Company

Sophisticated steel products and services. The Mexican automotive sector is the largest in Latin America and the seventh largest worldwide.

TERNIUM'S STEEL MARKETS

Ternium's customers range from small businesses to large global companies in the construction and industrial sectors. We report steel shipments under three geographical regions: Mexico, the Southern Region and Other Markets.

Mexico

The Mexican steel market is the largest in Latin America. The industrial sector, which in 2019 accounted for 53% of Ternium’s total shipments in the country, is the main driver behind an attractive high-end steel market segment.

Ternium's largest industrial customer in Mexico is the automotive industry. With 3.8 million vehicles produced in 2019, the local industrial hub is the largest in Latin America and ranks seventh in the world behind China, the US, Japan, Germany, India and South Korea.

The Mexican manufacturing industry is a fundamental part of a complex supply chain within the USMCA, and is prepared to supply highly sophisticated products for demanding end-user markets. In addition to the

automotive industry, the Mexican home appliance, HVAC and lighting manufacturers have also reached a high level of sophistication, requiring innovative and high-end steel products.

Southern Region

The Southern Region encompasses the steel markets of

Argentina, Bolivia, Chile, Paraguay and Uruguay. The Argentine steel market, the third largest in Latin America, accounts for most of Ternium's shipments in this region.

Ternium's industrial customer base in Argentina represented approximately 47% of Ternium’s total shipments in the country in 2019. The Argentine automotive industry, the third largest in Latin America, is part of the value chain within the Mercosur, a customs union encompassing Argentina, Brazil, Uruguay and Paraguay that has eliminated or significantly reduced import duties, tariffs and other trade barriers among member states.

Other relevant industrial sectors in Argentina include the agro machinery, cans and home appliance manufactures, and the oil & gas sector.

12. Ternium

High-end steel. An attractive market segment.

Other Markets

Ternium’s finished steel customers in the Other Markets segment are mainly in the construction and energy-related industries in Colombia, the United States and Central America. Following the acquisition of Ternium Brasil in September 2017, Ternium started shipping steel slabs to third party steel companies mainly in the United States and Brazil.

A small share of Ternium’s shipments is destined for steel markets outside the Americas. Sales to Europe, Asia and Africa are carried out mainly through Ternium’s commercial office in Spain.

Chairman’s Letter

Over the past months, the global economy has been deeply affected by the COVID-19 pandemic. The measures taken around the world to contain the spread of the virus have resulted in a global crisis, whose speed and severity is unprecedented in recent history. Though, in many parts of the world, businesses are reopening, people are gradually returning to work, and developed country governments have implemented massive economic stimulus programs, the pandemic continues to spread and the recovery from the crisis will take time and hasten change in many fields.

Latin America is particularly affected, as its economies were already under stress and the number of affected persons continues to rise. We took prompt action to adjust the company for the crisis and a high level of ongoing uncertainty.

To protect our people and assure a safe working environment, we introduced new work protocols including mandatory use of face masks, temperature checks, strict social distancing rules and disinfection policies for company transportation, site entry and common working areas as well as applying work-from-home policies and testing every person showing compatible symptoms and their close contacts.

To secure the financial stability of the company, we are making full use of the opportunities we have for industrial integration to optimize production and overhead costs, reducing inventories and working capital and quickly adjusting our operations to the reduction in sales. We are delaying some of our investment projects, pushing out the startups of our new hot rolling mill in Pesqueria, Mexico, and our new rebar mill in Colombia, and thereby reducing our capital expenditure commitments for this year to $600 million from the $850 we had originally planned. We also elected to suspend our annual dividend payment for the 2019 fiscal year.

To support our communities, we established and deployed a $5.5 million fund to strengthen local medical response capabilities, using our global procurement network to provide ventilators, intensive care equipment and protective gear as well as constructing and operating a field hospital with 100 beds for the community of Monterrey in Mexico and providing infrastructure and equipment for intensive care units to other hospitals in Ensenada in Argentina and in Rio de Janeiro in Brazil. Our employees have responded with solidarity and purpose in joining these initiatives.

At a time like this, the support we provide to our smaller customers and suppliers through the ProPymes program is particularly relevant and we are reinforcing the financial help we provide to members of the program with $8.0 million applied among 125 companies, together with assistance in raising financing from local financial institutions. Our training programs have been reinforced with more webinars and online workshops reaching over 1,200 persons. Equally, as the gradual recovery advances, our Webservice digital integration portal, which is used by our commercial customers to place 80% of their orders, will facilitate safe working practices.

As we reflect on our achievements during the past year, this crisis is a reminder of the importance of a long-term management focus that addresses all aspects of the company’s performance and its relations with customers, suppliers, employees and the communities that sustain us. To better report on the actions we carry out on this respect, this year we completely

15. Sustainability Report 2019

Chairman's Letter

redesigned our Sustainability Report and strengthened it by using the guidelines established by the Global Reporting Initiative (GRI), including consultations with our stakeholders to determine material topics to cover.

Our operational and financial results in 2019, though down from the outstanding results of the previous year, were solid, with an EBITDA of $1.5 billion on sales of $10.2 billion. Even after investments of $1.1 billion in our expansion program, our free cash flow amounted to $595 million and we ended the year with net debt of $1.5 billion, which has declined further in the year to date.

We continue to consolidate our position as a leading Latin American steel producer with a strong focus on serving the industrial and construction sectors. In Mexico, we started up new galvanizing and painting lines expanding our product range for industrial markets, which account for over 50% of our sales in the country. With the recent enactment of the new USMCA agreement confirming a free trade area across North America, the Mexican automotive and industrial sector is well positioned for a post-pandemic recovery. Although we have delayed the planned start-up of our new hot rolling mill in Pesquería until 2021, this new mill will strengthen our competitiveness through further broadening our range of high-end industrial products and allowing further integration of our industrial system by using high quality steel slabs from our mill in Brazil. In times when regional supply chains are being strengthened, the new line will also reinforce our import substitution strategy.

At the center of the growing community in Pesquería, Mexico, lies the Roberto Rocca Technical School. Last year, the first cohort of students graduated following three years of study focused on technical education, including industrial apprenticeships. During the annual worldsteel assembly held in Monterrey in October 2019, Ternium received the Steelie Award for “Excellence in Education and Training” based on the achievements of the school and its pupils. Aside from our response to the pandemic, education at all levels remains the focus of our community programs, not only in terms of money spent but also in terms of the design and organization of programs that can contribute to improving the level of education, particularly technical education, and open educational opportunities at all levels in the communities where we operate.

Last year marked the 50th anniversary of the origins of the company in the inauguration of a cold rolling mill at Ensenada in Argentina. The construction and start-up of this greenfield plant, carried out by a highly motivated team of young professionals, has shaped the culture and management ethos of the company to this day. Providing a stimulating working environment and effective opportunities for employee training, education and development is a constant focus in our management efforts and critical to maintaining high levels of employee motivation. In August 2019, we inaugurated an in-house corporate university with responsibility for organizing knowledge and training across the company and developing a curriculum with participation from outside universities that provide employees the tools for their own education and development. In 2019, Ternium’s employees had an average of 62 hours of training and 662 employees participated in management development programs. In our most recent pulse survey on employee satisfaction, with an 87% participation rate, 83% of the respondents expressed their satisfaction with Ternium as a place to work.

16. Ternium

Safety and minimizing the environmental impact of our operations are paramount in our management focus and routines. In total, we invested $120 million during 2019 in projects aimed at improving our environmental, energy and safety performance by modernizing our facilities. Major investments include those aimed at reducing particulate emissions at our steel shops, significantly improving air quality and working conditions, and reducing water consumption rates in our facilities in Mexico which are located in a region of high water stress. We also advanced with the certification of our energy intensive operations under the new ISO 50001 standard. Now most of our steelmaking, hot rolling and finishing facilities in Brazil, Argentina and Mexico are either certified or under certification.

During the year, we revised our health and safety strategy, developing specific practices to prevent situations where our employees or contractors are exposed to severe injury, and establishing safety committees to strengthen the consultation and participation of workers and their representatives on health and safety issues.

We are active participants in worldsteel’s climate action initiatives, joining the recent Step Up Program to reduce carbon emissions through benchmarking, and have committed ourselves to the UN Global Compact and to advance its Sustainable Development Goals. In the past five years, we have implemented a number of energy savings initiatives which have yielded an annual reduction of 298,000 tons of carbon emissions. We are also working with industrial gases companies serving the soft drink bottling industry to recycle carbon emissions captured in our production system which should yield further annual savings of 60,000 tons. The challenge of reducing emissions to meet the Paris Agreement commitments is, however, of a different order of magnitude and will require a coordinated response from our industry alongside governments, customers and suppliers. Our ambition is to be at the forefront of our industry’s response to this challenge.

As we prepare for the future, we are confident that the company is well positioned to continue a path of sustainable growth as a leading supplier of steel products to the industrial sector in the Americas. Our ongoing investment program, the transformation of our industrial system using Industry 4.0 technologies, and the long-term focus developed since the origins of the company 50 years ago will enhance our competitive position and the sustainability of our operations over the coming years.

During these difficult times, I would like to give special thanks to our employees, who are showing exemplary solidarity and resilience. I would also like to thanks our customers, suppliers and investors for their ongoing support.

by combining the demand of products and services by both Ternium and our affiliate Tenaris. We pursue this goal through Exiros, a purchase and sale agency which we own 50/50 with Tenaris. Exiros has offices in various countries and is in charge of the procurement of a majority of our raw materials and other products and services.

A Significant Expansion of Ternium’s Industrial Capabilities

In September 2017, the company acquired a state-of-the-art slab facility in Rio de Janeiro, Brazil, with an annual production capacity of 5 million tons of high-end steel slabs, a deep-water harbor and a 490 MW combined cycle power plant.

With the addition of this mill, total crude steel production capacity of Ternium's industrial system increased 5.0 million tons to 12.4 million tons.

The Rio de Janeiro unit has provided Ternium with new business opportunities, particularly in Mexico. Following its acquisition, the company started the construction of new hot-rolling, hot-dipped galvanizing and painting lines in its Pesquería Industrial Center, Mexico, and strengthened its product research and

development capabilities. In addition, Ternium started the construction of a greenfield reinforcing bars facility in Palmar de Varela, Colombia.

The results of this transformation process started in 2018 with the inauguration of a new laboratory in Pesquería, which increased Ternium's product research capabilities for high-end industrial requirements. During 2019, the company started-up its new hot-dip galvanizing and painting lines in Pesquería, adding 350,000 and 120,000 tons of annual production capacity to Ternium's industrial system, respectively. These new facilities incorporated the most advanced painting technology to the Mexican steel industry, providing high-end value-added products for the HVAC and automotive industries.

Ternium's new hot-rolling mill in Mexico will have an annual production capacity of 4.4 million tons, with an option to increase capacity in the future by an additional 300,000 tons. With the addition of this new mill, Ternium's industrial system will increase total flat steel hot-rolling production capacity by 47% to 13.8 million tons. In addition, expected synergies between Ternium's new hot-rolling mill and its cold-rolling mill in Pesquería will result in an annual production capacity increase of

RESCHEDULED INVESTMENT PLAN FOLLOWING COVID-19 OUTBREAK

In order to mitigate the impact of expected lower sales resulting from the COVID-19 pandemic induced recession, Ternium has recently reduced its planned capital expenditures for the year 2020 by an estimated $250 million, to $600 million. Consequently, the inauguration of Ternium's new hot-rolling mill in the Pesquería Industrial Center has been postponed from 2020 to 2021, and the commissioning of the new reinforced bar facility in Palmar de Varela has been postponed from March 2020 until the second half of 2020. The final reduction in Ternium's capital expenditures in 2020 will depend on the pace of recovery of economic activity and steel market demand.

Strengthened Product Research and Development Capabilities

Steel is a highly versatile metal, offering a wide space for product innovation. For example, over 70% of the structural steel parts used to build a car today involve solutions that did not exist 20 years ago.

The properties of the steel products required by Ternium's customers are usually the result of a combination of their metal composition and the way metal gets processed into finished steel products. Ternium’s business strategy

is based on offering a complete range of value-added,

high-end products, with an emphasis on creating and manufacturing increasingly sophisticated steel products for new applications and industries.

A COLLABORATIVE APPROACH TO PRODUCT RESEARCH AND DEVELOMENT

At Ternium, we carry out applied research efforts in different ways. We develop steel products through in-house programs, joint projects with leading industrial customers, joint efforts with recognized universities or research centers, and through our participation in international consortia.

Ternium has identified synergies in collaborating with its customers in the early stages of their projects. Anticipating our customers' upcoming steel product requirements through our participation in joint development projects is key not only to build customer relationships but also to plan and develop new processes, which may sometimes require the addition of new equipment and technology.

Ternium’s research programs are open to a broad-based international network of industry consortia. Over 50 universities and research laboratories from both the public and private sectors collaborate with Ternium. The goal is to find and develop the best solutions to

company has acquired various steelmaking and steel

processing facilities in Mexico, Brazil, Argentina, Colombia, the United States and Central America, that resulted in a myriad of legacy industrial information technology (IT) systems. Ternium's business model required a unified industrial system able to offer an ample range of products and services to its customer base. The implementation of this unified model implied a significant effort of digital transformation. For example, after the acquisition of Hylsamex in 2005 and Grupo Imsa in 2007, there were 28 different information technology systems that had to be consolidated into a single one.

With that target in mind, by 2009 we were able to bring Ternium on-line in real time with a single, unified information technology system, spanning all of its facilities. Once this process was completed, the company extended its digital tools to its customers and suppliers, enabling the integration of its processes with theirs.

This integration was implemented through the development of a digital marketplace called "WebService". Nowadays, approximately 80% of Ternium’s commercial orders are placed through this tool, enabling an efficient business to business interaction.

CERTIFICATION OF TERNIUM'S INFORMATION TECHNOLOGY SYSTEMS

In May 2017, after a two-year preparation process, Ternium certified its information technology system under the ISO 20000 standard. This standard describes the best practices in the management of an organization's IT processes and services.

This certification process has helped the company to optimize costs, resources and processes, enhance customer satisfaction, strengthen the performance assessment of its IT system, increase compliance with multiple regulations, and increase overall business competitiveness.

SMART FACTORY

Ternium is making progress in the construction of a SMART factory, the acronym for Social, Mobile, Analytics, Robotics and (internet of) Things. This concept, supported by the company’s unified information technology platform, ensures a constant stream of knowledge and information (data and events) that will lead its facilities to a more productive and efficient evolutionary stage.

Users achieve a more efficient performance by interacting from any location (offices, facilities or elsewhere) through different kinds of devices.

Employees working in Ternium's industrial, commercial and maintenance areas are equipped with mobile devices that enable them to perform all their tasks from any location with a remarkable increase in productivity.

Analytics and data correlation detect patterns for various applications to increase safety and efficiency, and to reduce costs. Through video-feed analysis (machine learning), new applications include real-time detection and reporting of unsafe situations or behavior within the facilities to prevent accidents and, using drone technology, the identification of potential damages in either tall structures or confined spaces, whether internal or external, as well as the assessment of bulk material stockpiles. Drones substitute human inspection at height and minimize the risks inherent to this type of tasks. In 2019, the system autonomously issued 440 maintenance tickets, removing human inspection at 55 roofs.

areas, verify the observance of marked pathways and social distancing, and monitor the use of safety helmets, vests and face masks. Deviations from protocols are automatically reported to the relevant manager with the ultimate purpose of preventing accidents based on early detection.

In addition, radio frequency identification (RFID) technology enables the automated handling of steel products in the yards, speeding up logistics and increasing safety. Ternium’s RFID project is intended to identify and track each coil from the moment it reaches the yards until shipment, facilitating inspections procedures, improving inspectors' safety and reducing operations lead times. The tracking system has already been implemented in 27 stockpile yards in Mexico and Argentina.

In the maintenance area, analytics and data correlation technology has proved its potential with the prediction of failures two to three weeks in advance. During 2019, we applied this technology to the continuous casters at the company's Mexican and Argentine facilities.

We plan to apply this technology in the company's most critical production lines to shield strategic equipment and significantly reduce non-operational interruptions and,

therefore, the impact on the production process. In order to support Ternium's analytics needs across all business functions, we have implemented a single technological platform, known as Data Lake, that meets all our big data and analytics requirements.

Other projects aimed at improving safety and productivity are the use of virtual reality software for training purposes, the use of augmented reality for experts providing remote assistance to operators, 3D printing and the use of 3D scanning for several applications. We have also developed virtual reality software to train employees on risk perception. This software simulates risky situations in 3D, depicting potential sequences that could end up in fatal accidents.

In addition, we have successfully finished the proof-of-concept stage for replacing on-site crane training exercises with virtual reality training facilities, simulating the cabins of the three types of cranes used by Ternium: magnetic crane, hook crane and dump. We have also developed a virtual reality software to train our personnel on specific operating procedures performed in the secondary metallurgy area of our steel shop in Argentina. In Mexico, we are developing

projects to train employees in water leakage protocols and in productivity enhancement using digital twin technology. This technology generates a digital replica of physical assets, processes, people, sites, systems and devices that can be used for various purposes.

Ternium has seven administrative robots in operation, running automated processes and tasks in the areas of accounts payable, accounts receivable, sales back office and industrial engineering administration. We are advancing projects to gain productivity in accounts payable tasks in Mexico and Argentina, where more than 50% of all suppliers' invoices are expected to be loaded in our systems using robots.

CONCERTED RESEARCH EFFORTS IN THE QUEST FOR INNOVATIVE IT SOLUTIONS

Through cooperation agreements with two universities, Ternium has engaged 110 students in twenty Industry 4.0 projects.

GOOD RESULTS IN A CHALLENGING YEAR

During 2019, shipments in the Mexican market were 6.3 million tons, representing 50% of Ternium’s total steel shipments. Apparent flat steel use decreased in the year reflecting a softer commercial market in 2019 and a strong level of shipments in the first half of 2018 in anticipation of rising steel prices.

Shipments in the Southern Region reached 1.9 million tons in 2019, or 15% of Ternium’s consolidated shipments in the steel segment. Most of Ternium’s shipments in the region are destined for the Argentine market. Apparent steel use decreased significantly in Argentina in 2019, as the country's macroeconomic situation deteriorated.

Shipments in the Other Markets region reached 4.3 million tons in 2019, or 34% of Ternium’s consolidated shipments in the steel segment. Our major shipment destinations in the Other Markets region were the United States, Brazil, Colombia and Central America.

Net sales in 2019 were $10.2 billion, including net sales of steel products for $9.9 billion on steel shipments of 12.5 million tons, net sales of other products for $296.1 million and net sales of iron ore products for $364 million on iron ore shipments of 3.6 million tons.

Most of the iron ore production was consumed in our own steel operations. Steel revenue per ton was $790

in 2019. Steel prices declined in North America during the year, following a strong pricing environment in 2018.

EBITDA reached $1.5 billion in 2019 with EBITDA margin of 15%, remaining at an industry-leading level of profitability.

Net income attributable to Ternium's equity owners was $564.3 million, or $2.87 per ADS. Free cash flow was $595.4 million, with a high level of capital expenditures being partially offset by a $572.7 million reduction in working capital.

SOUND FINANCIAL POSITION

In 2019, the company’s capital expenditures were $1.1 billion, $532.0 million higher than in 2018, as Ternium's investment program progressed as planned.

The main investments during the year included those made for new hot-rolling, hot-dipped galvanizing and painting production capacity in the company’s Pesquería industrial center, a new steel bar and coil mill in Colombia, the improvement of environmental and safety conditions at certain facilities, the expansion of connectivity, integration and automation of our operations, and those made in the iron ore mining operations.

Ternium's net debt position reached $1.5 billion at the end of December 2019, with a net debt to last twelve months EBITDA ratio of 1.0.

Fast implementation of COVID-19 mitigation measures. New protocols for on-site working and work-from-home policy whenever possible.

Ternium ranks occupational health and safety (OH&S) performance as its top priority, with the conviction that all injuries and work-related illnesses can and must be prevented. Each of the company's and third-party employees' OH&S is our top concern.

COVID-19 Outbreak

Ternium is focused on safeguarding the OH&S of its employees, customers and suppliers based on best practices that comply with and, in some cases, exceed local governmental directives. Beyond implementing work-from-home policies wherever possible, the company has looked to protect the safety of those employees working on-site by adopting stringent social distancing, temperature check and disinfection policies at all transportation, site admission, working post and cafeteria locations, among other initiatives. In addition, Ternium has developed a protocol to track suspect or positive contagion cases and the successful reintegration of returning workers.

New Occupational Health and Safety Corporate Strategy

According to Ternium's OH&S policy, the assessment of risks and management of our people's OH&S must be integrated into all our business processes. Management is responsible and accountable for

achieving excellence in OH&S performance as part of a comprehensive set of goals. In December 2019, Ternium launched a new corporate strategy on OH&S. We are committed to taking every possible step to protect the safety and health of our employees and the people of the communities in which we operate. This vision has acted as a framework to adjust our strategies and to adopt new ones, including the alignment of our safety culture to our vision, the prevention of severe accidents or fatalities, the achievement of excellence in process safety management, the engagement of employees through effective communication and the engagement of customers' and suppliers' managers and employees to embrace our vision and goals. In 2019, Ternium invested $50 million under its safety-focused capital expenditures plan.

Occupational Health and Safety Management System

Ternium has an OH&S management system to oversee its production units, which abides by the company's OH&S policy, and local and national laws and regulations. The company periodically audits its processes and procedures, which helps us find new opportunities to improve our safety management systems and ensure their compliance with our policy.

Guatemala have their OH&S management system certified under international standards by third party certification bodies. The company’s facilities in Mexico have completed the migration process of their OH&S management system to ISO 45001:2018, and have

obtained the certification in this new standard. Ternium’s Rio de Janeiro unit in Brazil and its mining facilities in Mexico are undergoing a migration and certification process, which is expected to be completed within the next two years.

Aligning Our Safety Culture to Our Vision

Ternium’s continuous quest for a virtuous safety culture leans on its top management’s effective leadership. The company’s senior management has identified measurable, repeatable, proactive and leading safety attitudes to deploy along the organization, as part of a strategy to align people’s safety culture with the company’s vision.

SAFETY FIRST PROGRAM

The Safety First program fosters a pro-active approach to safety issues to prevent incidents and accidents. One of the program's main tool is the Safety Hour initiative, in which middle and senior managers tour operating areas for an hour, three times a week, to identify safe behaviors to be consolidated or unsafe acts or situations to be

addressed through an open dialogue with employees. This exchange helps identify potential risks and enables a fluid and constructive feedback to implement effective preventive measures. In 2019, the company held a total of 147,100 Safety Hour sessions, with the regular participation of 1,600 employees and contractors, that helped to detect, record and correct 177,500 deviations. In addition, these sessions helped to recognize 106,800 full-compliance cases. Furthermore, management performed safety verification audits (SVAs) at the facilities to evaluate compliance with policies, procedures and practices in relation to relevant OH&S topics. In 2019, a new record 200,000 SVAs were performed.

TEN LIFE-SAVING RULES

Ternium has established Ten Life-Saving Rules, which lists the actions that all employees must follow in order to protect their lives and that of their colleagues. The rules are the result of a process that included worldsteel's guidance, and the contribution of focus groups and studies performed to detect the main causes of risks in our operations. The rules are backed by practices and routines to follow and reflect the scope of safety regulations in the countries where Ternium operates. The rules have been extensively communicated throughout Ternium’s operations to foster employees',

customers' and suppliers' awareness, and have been audited to ensure their observance. In 2019, we held 42,800 compliance audits.

TERNIUM’S ANNUAL SAFETY DAY

Since 2014, every July 22nd we have been holding Ternium's Annual Safety Day, an occasion to prompt a renewed commitment to improving safety and increasing risk awareness, in the belief that every accident can and must be prevented. During this event, we hold safety management meetings and discussions to review our performance in the past year and agree on concrete actions to improve safety in every facility.

TRAINING PROGRAMS

Management is committed to training Ternium's employees, customers and suppliers on the appropriate application of the company’s OH&S management systems in performing their tasks, and to raising awareness of risks. In 2019, Ternium delivered 487,600 safety training hours to 15,700 employees, customers and suppliers.

TASK REJECTION TOOL

This tool aims at strengthening people’s determination not to start or, if started, to suspend a task under certain conditions. The Task Rejection tool helps people prevent

injuries risks stemming from the lack of effective control over identified safety risks.

Prevention of Severe Injuries or Fatalities

A steel industry-wide analysis found out that, over time, the downward trend in fatal accidents has been slower than the trend for non-fatal accidents, mainly due to causality differences. Accordingly, the company has increased its efforts to identify severe injury or fatality precursors. In order to do so, we identify non-controlled repetitive precursors through interviews with employees, based on critical control and verification methodologies.

Process Safety Management

Iron ore processing, and steel production and processing include potentially hazardous processes. Ternium has identified critical processes in some of its facilities, and developed specific tools to manage them. In addition, during 2019 Ternium launched a new program focused on the identification of risk factors in critical processes and the development of specific strategies aimed at eliminating the exposure to severe personal injury.

Engaging Through Effective Communication

Over the years, Ternium has increased the visibility of safety issues through its communications platforms.

Our agenda includes videos, articles and the coverage of selected events. To engage the company’s employees and raise awareness on safety issues, we have developed a new communications system aimed at sharing key messages with employees operating at every location, including posts at the company’s communications platforms and other distribution channels. We have also implemented the Five-Minutes Safety Talks, an open-dialogue instance for blue-collar supervisors and their teams to analyze OH&S issues selected every week by senior management.

Engaging Customers' and Suppliers' Managers and Employees

We aim at having all contractors' employees embrace our vision and goals. With this purpose, we have launched several initiatives including working meetings with contractor’s top managers and the participation of their employees in Ternium's OH&S workshops. We have recently launched an OH&S improvement plan for contractors. This plan has been developed based on contractors' best practices, which were identified through a benchmark of contractors' operations at the company's facilities in different locations and countries.

Accidents and incidents

In 2019, Ternium recorded an injury frequency rate (IFR) of 2.7 injuries per million of hours worked, compared to

an IFR of 3.0 in 2018. The lost time injury frequency rate (LTIFR) was 0.8 day-loss injuries per million hours worked in 2019, compared to an LTIFR of 0.7 in 2018. The year-over-year increase in LTIFR in 2019 reflected mainly the effect of construction works carried out for the new facilities in Pesquería, Mexico, and Palmar de Varela, Colombia.

Analysis of Accidents and Incidents

Ternium's management follows specific protocols when a workplace accident or incident occurs, regardless of the damage or injury, or lack of, cause by an event. The research and analysis of an event is conducted by multidisciplinary teams that include the participation of the manager with direct responsibilities in the area involved.

An event is analyzed through a causal factor tree methodology that has been homologated at Ternium. Management uses all available resources that could contribute to the understanding of an event, including the evidence collected by nearby cameras. Once causes are fully understood, the company implements a new preventive action plan structured in hierarchy of controls. This methodology was incorporated in the company’s occupational health and safety management system in 2019.

including tailings dams. 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.

In late 2019 and early 2020, Ternium and Consorcio Peña Colorada concluded new stability studies in certain of their tailings dams that are closed or stand-by, in order to proceed to final closure with stricter and more conservative standards for seismic areas. As a result of those studies, performed by recognized consultant companies, and in order to meet those new stability standards and mitigate risks, Ternium and Consorcio Peña Colorada are planning to reinforce certain stand-by and closed tailings dam sections in Alzada and Guasimas, respectively.

In addition, a new paste plant was started-up in July 2019 near Consorcio Peña Colorada's Arrayanal dam, to increase the efficiency and speed of water recovery from the dam tailings. With this initiative, Ternium expects to increase the solid content of tailings from 45% to 68%, increasing the stability of the dam and freeing space for additional tailings.

   Minimizing Ternium's Environmental Footprint

• Standardized management system certified under ISO 14001 and 50001

• Continuous progress in environmental management performance

• Management performance accountability

• Investment in best available technologies

The protection of the environment is a fundamental value for Ternium. The company seeks to reach the highest standards of environmental and energy performance in order to minimize the environmental footprint of its operations. To achieve this, we are continuously working on the improvement of Ternium's production system. The company's Environmental and Energy Policy states Ternium's views regarding the preservation of the environment.

The monitoring of the company's environmental performance leans on an environmental and energy management system encompassing all its production units. Ternium periodically audits and certifies its systems and procedures. This process helps us identify improvement opportunities, update the company's environmental management processes and make sure Ternium complies with legal regulations.

Ternium’s steel and mining operations are subject to a broad range of environmental laws and regulations relating to the protection of the environment, such as land use; air emissions; wastewater treatment and discharge; the use, handling and disposal of hazardous or toxic materials and the handling and disposal of solid wastes. Ternium’s corporate environmental and energy policy commits each of its business units to comply with all

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 of regulatory changes are addressed primarily at national level. Ternium has not been subject to any material penalty for environmental violations in 2019.

Ternium's environmental and energy management system at its steel production facilities is certified under ISO 14001, ISO's environmental management standard. This standard was created by the International Organization for Standardization, a network of national standardization institutes that work together with governments, the industry and consumer representatives with the purpose of supporting the implementation of an environment management plan in public and private organizations.

In addition, Ternium is certifying the system at its energy intensive operations under ISO 50001, ISO's energy management standard. The system has already been certified at the Rio de Janeiro unit, at the steel shop of the San Nicolás unit and at the Pesquería unit (downstream facility), and is undergoing the certification process at the steel shop of the Guerrero unit and the hot-rolling mill of

The company has recently launched a new project to increase its carbon dioxide capturing capacity, which is expected to be completed in 2021. This project will enable a yearly increase in carbon dioxide emission savings of up to 60,000 tons, to a total of 270,000 tons.

the San Nicolás unit. Ternium's environmental and energy management system will help the company maximize its efforts to reducing carbon emissions. The targets of the company in this regard are in line with those of the countries in which Ternium has operations and are expected to contribute to the achievement of the goals of the Paris Agreement adopted at the UN climate change conference.

A Material at the Heart of a Low-Carbon Economy

Ternium subscribes to worldsteel's position as for the role of steel in our present and future. Abundant iron ore resources, endless recyclability and unparalelled performance make steel the material of choice in a low-carbon circular economy. We rely on steel for our housing, transport, food and water supply, energy production, tools and healthcare. Almost everything around us is either made of steel or manufactured by equipment made of steel. Steel is a highly versatile metal, offering a wide space for the development of new workable and light products. Innovation is driving to increasingly sophisticated ferrous castings, enabling a new generation of stronger and lighter structures, with lower carbon footprint, that are essential inputs for the automotive, engineering, energy and transport industries. Iron ore is currently the main raw material for steel production, a material that ranks among

the most common in the world. Steel scrap has been growing as an alternative raw material for steel production. In addition to keeping the attributes and performance of steel upon recycling, steel scrap has magnetic properties that enable feasible separation technologies. The use of steel scrap reduces carbon emissions from the steel life cycle. In combination with a long history of significant efforts to increase recycling rates, this has resulted in steel leading the recycling statistics, for example in cars and cans. Furthermore, its biodegradable nature positions steel as a solution to our society's waste disposal challenge.

Steel recycling is limited by the availability of scrap, due to the relatively long life of steel-based products and infrastructure. Developing economies have relatively young infrastructure stocks and have, therefore, limited amounts of obsolete steel scrap to use in steelmaking. However, as these economies’ climb the development curve, and infrastructure enters the replacement phase, availability of obsolete scrap increases, supporting a shift from steelmaking technologies based on iron ore to steelmaking technologies relying more heavily on steel scrap. In time, this shift will have a significant impact on trends in iron ore and steel scrap consumption globally.

Energy and Climate Action

The steel industry is energy intensive. There are two main technologies for producing steel: the blast furnace / basic oxygen furnace (BF/BOF) route, which consumes mainly iron ore and uses metallurgical coal as its main energy source; and the electric arc furnace (EAF) route, which consumes mainly steel scrap and/or direct reduced iron and uses electricity as its main energy input. Direct reduced iron is produced out of iron ore and uses natural gas as a reduction agent. The steel industry has a strong commitment towards the reduction of greenhouse gas (GHG) emissions, through the development of innovative steel products for a successful low carbon society and the improvement of steel production processes. According to worldsteel, in the last 50 years the steel industry reduced its energy consumption per ton of crude steel produced by 60%. Yet, steel production accounts for approximately 8% of all human-made GHG emissions.

As a member of worldsteel, Ternium is signatory of worldsteel's sustainability policy and joins its efforts, through the company's participation in several programs, to reduce carbon dioxide emissions. As a participating member, Ternium submits to worldsteel its performance indicators to contribute to its statistics and databases, which enable steelmaking companies to benchmark

performance, share best practices and ultimately set improvement plans for their industrial processes. In 2008, worldsteel launched its Climate Action Recognition Program. Since its launch, Ternium has been recognized by worldsteel for its compliance with the program's requirements for carbon dioxide emission reporting.

In 2019, Ternium joined worldsteel’s Step Up Program. This initiative supports the steel industry's efforts to reduce carbon dioxide emissions by means of better operational models and benchmarking of operating technologies. Based on the Step Up Program findings, Ternium seeks to identify opportunities to improve the efficiency of its operations, mainly related to raw materials usage, energy input, materials yields and maintenance models.

Ternium's carbon dioxide emissions totaled 18.5 million tons in 2019, 3% lower than in 2018. Steel production totaled 10.3 million tons, decreasing 6% year-over-year. Average carbon dioxide emissions per ton of crude steel produced, including scopes 1, 2 and 3, was 1.8 tons in 2019, 2% higher than in 2018 mainly due to a net lower operating rate. Ternium's average energy consumption per ton of crude steel produced was 22 gigajoules in 2019, 3% higher year-over-year for the same reason. Ternium's

carbon footprint includes only carbon dioxide emissions, as the incidence of other greenhouse gases is negligible.

The assessment of the company's energy consumption is based on worldsteel's sectoral approach methodology in accordance with ISO 14404.

In 2014, Ternium launched an energy efficiency program, an initiative aimed at reducing GHG emissions by identifying opportunities to implement energy savings at its production facilities. Since 2014, we have completed 366 projects under this program that, in the aggregate, have reduced Ternium's yearly carbon dioxide emissions by approximately 298,000 tons, comparable to the yearly emissions from 117,000 cars.

During 2019, Ternium's Rio de Janeiro unit started purchasing biomethane from a nearby waste landfill. The company expects to gradually increase the use of biomethane to replace natural gas, for up to 30% of its historical consumption level, with the consequent avoidance of carbon dioxide emissions in the landfill.

Air Quality

Some of Ternium's facilities, like the company's Industrial Center in Pesquería, adopted the best-available

technologies from the design phase. In other facilities, particularly those acquired, Ternium is enhancing its air quality monitoring systems and is consistently adopting the best-available technologies as part of its drive to continuously improve its environmental performance.

Ternium has made investments of approximately $137 million in its facilities in the last five years to improve the capture and treatment of air emissions. In 2019, the company concluded the construction of a new bag filter for the fume and dust capturing system at its steel shop in the Puebla unit in Mexico, and made progress in the improvement of the fume and dust capturing system at its steel shop in the San Nicolás unit in Argentina.

In addition, Ternium concluded works in the electrostatic precipitator of the sinter facilities at its Rio de Janeiro unit in Brazil. To mitigate dust emissions in all its operations, Ternium implemented specific solutions, such as retaining walls and live fences at bulk storage yards, washing systems for truck tires and road pavement.

In 2019, Ternium launched a project to capture and

contain emissions at the iron ore handling equipment and direct reduction facilities in its Guerrero unit in Mexico. In addition, the company launched a project to control sulfur

Water Management

In steel manufacturing, in which water plays a major role, most water is recycled and returned to the source. Ternium is fully aware of its responsibility for managing water resources. Its water management strategy is designed on a case-by-case basis in accordance with the specific situation at each of its operating sites.

The company continuously incorporates best available technologies to improve water management and water discharge monitoring systems. For example, Ternium has recently revamped a water treatment facility in the steel shop of the San Nicolás unit, to improve the quality of recirculated and discharged water. Ternium has invested a total of $72 million in the last five years to improve its water management.

WATER INTAKE AND USE

Consequently, Ternium has developed specific strategies to minimize water usage, reflected in a water consumption rate of 4.3 cubic meters per ton of crude steel produced in its steel shops in Mexico.

In this country, Ternium has consistently reduced the consumption of subsurface water by increasing the usage of treated or sewage water. As a result, the company's consumption of subsurface water decreased from 11.0 million cubic meters in 2015 to 9.4 million cubic meters in 2019, or 52% of total water consumption.

Total water consumption in 2019 also included a 23% share of third party treated water, a 17% share of external sewage water and an 8% share of recycled water.

WASTEWATER DISCHARGE

Ternium permanently monitors wastewater discharges, in compliance with local environmental regulations. The company designs capital expenditure projects to incorporate best available technologies and monitoring systems to reduce and improve the quality of water discharges. During 2019, the company concluded the construction of a new runoff water pumping station for the coal and coke yards, the coking batteries sector, the

co-products facilities and nearby areas at its San Nicolás unit in Argentina. In addition, it built new infrastructure to prevent discharges to the Paraná river in the event of extreme weather conditions.

This investment followed other investments in previous years like the gas scrubbing circuit-close at a blast furnace and a new runoff water capturing system at the sinter yard.

Life Cycle Assessment (LCA)

Ternium supports worldsteel's efforts and customer requirements to assess the environmental impact of steel products. The aim of this program is to document and improve the overall environmental profile of the company's offerings.

A steel LCA involves a thorough inventory of the energy and materials that are required across the industry value chain, according to ISO 14040 and 14044, to determine the global warming potential of steel products, among other indicators. In 2019, Ternium incorporated 63% of its crude steel production to its LCA inventory reporting, reaching a total LCA inventory reporting of 92% in the year.

Material Efficiency

In Ternium we continuously develop strategies to maximize the use of co-products and reduce the production of waste. We believe that the recovery and proper use of co-products is central to the application of circular economy concepts in the steel industry's value chain.

The use of co-products reduces the consumption of raw materials and energy, with a positive effect on carbon dioxide emissions and waste generation. All the steel scrap generated in Ternium's facilities is recycled. In addition, the company purchases steel scrap generated by other steel processors in its value-chain and steel scrap gathered by recyclers. In 2019, Ternium recycled 2.8 million tons of steel scrap to produce new steel with all its properties, representing 27% of its total crude steel production.

The granulated slag generated in the blast furnaces is sold to the cement industry. The re-use of granulated slag as a substitute for clinker enabled carbon dioxide emission savings in the cement production process of 1.3 million tons in 2019. The slag generated in the steel shop is also used to consolidate roads. In addition, Ternium has sinter and briquetting facilities that enable it to recycle different materials captured by

its air and water cleaning equipment, including iron ore fines, coal, lime and dolomite. Furthermore, the dust generated by the electric-arc furnaces at Ternium's Guerrero and Puebla units, Mexico, is transformed into Mix Rock^®, an innovative co-product developed and registered by Ternium. Mix Rock^® enabled the re-use of dust and slag as a substitute for iron ore in the clinker production process at the cement industry. In 2019, Ternium sold 86,000 tons of Mix Rock^®.

The processing of metallurgical coal for the steelmaking production process yields significant volumes of co-product gases. These gases stem from the distillation process in the coking batteries. Ternium cleans coking battery gases and obtains chemical products like tar, benzol and hydrated lime that are sold to third parties. In addition, once the gases obtained from the coking batteries, blast furnaces and, in the case of the Rio de Janeiro unit, the steel shop, are cleaned, they are used to produce steam for the generation of electricity.

All these processes have enabled Ternium to achieve a material efficiency rate of 99.6% in 2019, with 4.8 million tons of co-products generated and 60,300 tons of waste disposed of. Co-products mainly include blast furnace and

Training is a key component of Ternium's strategy in its pursuit for performance excellence.

Development and Training

Our constant pursuit of excellence in Ternium's operations requires a continuous search for improvement and innovation from our teams. We believe training is a key tool to achieve this goal. Over the last five years, each salaried employee has received an average of 47 hours per year of training and each hourly employee has received an average of 107 hours per year of training.

TERNIUM UNIVERSITY

In August 2019, the company inaugurated its corporate university. With the mission of learning, sharing and growing, Ternium University provides its employees with career development activities and programs. In addition, this project is expected to support the company's business transformation through its culture, to develop and shape the company's leadership, and to foster excellence in technical and functional skills and in the development of professional networks.

The project, launched in 2018, involved a team of 50 professionals from the Human Resources, Corporate Communication and Information Technology areas of the company. Ternium University is expected to be fully operational during 2021.

Ternium's corporate university provides its employees with career development activities and programs.

Ternium's programs for professionals spans a person’s entire career, from the initial level as a young professional to management levels. During 2019, 662 employees participated in different management academy programs.

Among these initiatives, the Leaders’ Development Program provides dedicated training for the company’s current and future leaders. The course is designed to enhance middle management leadership skills, as they advance their careers.

Approximately half of the company’s middle-level managers have taken part in the program. The leadership course is a joint effort with the EGADE Business School of Monterrey, Mexico, and the Torcuato Di Tella University of Buenos Aires, Argentina.

Our program for hourly employee supervisors includes a 40-hour course discussing the components of the supervisory role with a focus on hard and soft skills. This course has received the Excellence in Practice Award from the Association for Talent Development. A total of approximately 1,300 supervisors have completed the course since its launch in 2015.

The individual performance of each of Ternium's salaried employees is assessed annually through a formal performance assessment process. The results of the evaluation process drives different aspects of an employee's corporate life, such as compensation and career development, training requirements and performance improvement opportunities.

Ternium relies on a human resources IT system to manage its performance assessment processes. The system includes a set of measurable objectives for each employee under a 360-degree approach to the process. This is a key component of the performance assessment process as it ensures that everyone’s goals are in line

The evaluation of the accomplishment of objectives is addressed through a combination of different views: the actual employee, internal customers, assessment committees and feedback meetings, as well as mid-year reviews. The system offers employees additional options to provide and receive assessments, including the possibility of submitting client-supplier opinions related to specific objectives.

In addition, the system includes an upward feedback tool for management positions accessible to the manager’s supervisor. Although this tool is not mandatory, 94% of our managers received feedback in 2019's performance assessments, an indication of the credibility achieved by Ternium´s procedures. A performance assessment process based on a measurable set of objectives is an important aspect of our Human Resources Policy. It aims at improving our employees’ working experience throughout their careers and their relationship with their supervisors.

Ternium's 50^th Anniversary

Ternium's

50^th Anniversary

Back in 1969, the company inaugurated its Ensenada unit in Argentina, its first facility. The execution of this greenfield project and its start-up process, carried out by a trained and motivated team of young professionals, shaped Ternium's management profile.

THE COMPANY'S FIRST FACILITY
11 MONTHS TOOK THE CONSTRUCTION OF THE ENSENADA UNIT'S GREENFIELD FACILITY	2,000 PEOPLE WORKING ON THE FACILITIES' CONSTRUCTION SITE
3 MONTHS TO GET THE MILL UP AND RUNNING

A 50 Year Legacy

The startup of a greenfield project constitutes a memorable milestone for any company. Even more so if it is the first one.

This is the history of Propulsora Siderúrgica's facility in Argentina, today the Ensenada unit, which back in 1969 gave shape to the vision and values of Agostino Rocca, founder of the Techint Group, and the group of young engineers who decided to embrace a unique industrial challenge.

Now, as it celebrates its 50th anniversary, its industrial legacy has expanded around the globe, reflecting the values and commitment of its founders and the group of talented engineers who, at a very young age, embraced the dream of creating an industrial colossus in what had been an isolated estuary.

The Challenge

The facilities included a cold-rolling mill and a port with an annual production capacity of 350,000 tons. From its inception, Propulsora's plant was envisioned to become a milestone in the development of the entire Techint Group. The development of the project, its construction and inauguration took 33 months.

For the company it was not only a complex technological challenge but a great responsibility, as Propulsora was expected to meet Argentina’s rapidly growing demand for steel. But building the mill was not the only challenge faced by the company at the time. More importantly, it had to bring together a team of talented professionals with the skills, passion and commitment to get it up and running.

The Team

“If you want new things to happen, you need to hire young people”, said Agostino Rocca at the time. The company chose to hire young people with little experience but with optimal development potential, people with a mental and professional structure prone to change, flexible, with a strong sense of integration between personal and business objectives.

62. Ternium

Ternium's 50^th Anniversary

The company wanted to develop a creative environment where the weight of all individuals was given by their specific tasks and responsibilities and not by external symbols of authority.

Having placed such a huge capital in the hands of people with great enthusiasm and potential but with

really few developed competencies was definitively not a minor risk, but it meant a turning point in the

professional profile of the Techint Group.

Training

Even while works at the mill site continued, a group of close to 120 people traveled to Italy in early 1969 to be trained at an Italsider facility in Novi Ligure.

The experience abroad, in a foreign country, gave birth to Propulsora’s team spirit, in circumstances that led people to build stronger ties with their partners.

Construction of the Facility

The construction of the facilities was completed within just eleven months by Techint S.A.C.I., which was responsible for civil works, electrical and mechanical assembly, with more than 2,000 people working on the site.

This was a true EPC (Engineering, Procurement and Construction) project, which required an integrated and efficient interaction between the different functions.

Considering the speed at which decisions had to be made, observing tight schedules and rigid cost controls, the organizational autonomy was only possible thanks to the total harmony between all different participants.

Start-Up

As the “Novi Ligure team” came back to Ensenada in September 1969, they were surprised to see that the mill was already there. However, there was no time to contemplate the new industrial beauty.

The team had now to get it up and running in a record time of three months. And so they did.

On November 7, 1969, the annealing plant began operating and the opening of the port took place the following day. On November 13th, just 26 months after the main orders were issued, the first steel sheets cut at the plant began to leave the packing lines.

On December 23, the first coil in the scaling line was processed and the first cold-rolled coil by Propulsora was expected to leave the tandem the following day, which technically - and symbolically - took place on Christmas eve.

A few days later, in his year-end wishes to company employees, Roberto Rocca expressed:

“We have reached the end of this year (1969) with the satisfaction of having carried out the most important work of all that we have planned and promoted to date: Propulsora."

"We focus on it all our capacity, our passion and professional and entrepreneurial pride to fulfill our commitment to give the country a modern industrial plant that contributes to its economic development.”

“Everything has been possible for a unity of efforts, in which many qualities were combined: vision of the future, affection for the country, personal drive and eagerness for progress. Therein lays our success. In that imponderable predisposition you all have to get things done.”

"

We have reached the end of this year (1969) with the satisfaction of having carried out the most important work of all that we have planned and promoted to date: Propulsora.”

Small and medium-sized enterprises in the steel industry value chain in Argentina are encouraged

to expand their businesses abroad with the support of Propymes Exporta. This initiative offers industrial, commercial and financial support to help companies achieve their business goals, leveraging on their export potential.

Ternium offers support to small and medium sized 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 1,800 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 whole value chain of the best practices utilized in the industry.

Why Should Ternium Help Other Companies?

Ternium believes that its role as a large industrial company in Latin America is to strengthen its value chain. The ProPymes program was first launched in Argentina in 2002, during a deep economic crisis that severely affected many companies in the steel industry value chain. It has been named after the acronym PYME, which in Spanish stands for SME. In Mexico, the program was introduced four years later.

ProPymes institutionalizes the cooperation between Ternium and the company’s small and medium-sized customers and suppliers. Ternium works with SMEs to

help them reach their potential, enhancing their professional, management and financial capabilities, and helping them participate competitively in both domestic and foreign markets. A strengthened value chain fosters, in turn, the development of industrial infrastructure at Ternium's main markets, with increased steel demand and enhanced competitiveness.

ProPymes Assistance Services

TRAINING

ProPymes designs and implements an annual training agenda. The course contents are continuously updated to offer our customers and suppliers the best available tools and management practices for their salaried and hourly employees, as well as for managers. Every year the program incorporates additional subjects to the curriculum to meet SMEs' increasingly sophisticated range of needs, as they advance their learning curves.

Training activities are performed in-house or at universities or business schools. During 2019, ProPymes has sponsored training courses for 5,300 attendants, who spent an aggregate 87,400 hours in class.

INDUSTRIAL MANAGEMENT

ProPymes' industrial assistance services focus on a broad array of issues from the use of automation technology, the

optimization of production facilities and quality certifications, to the development of environment, health and safety protocols and human resources management. During 2019, ProPymes assisted 451 SMEs with theirindustrial projects.

INSTITUTIONAL INITIATIVES

ProPymes institutional assistance helps SMEs develop strategies aimed at ensuring a level playing field in the local market, given the potential threat of increased unfairly traded imports.

Assistance initiatives include those for the setting of industry chambers, the development of technical standards for industrial products and those aimed

at improving SMEs competitiveness. In addition,

we help SMEs set their own corporate social programs through the implementation of a support program for technical educational institutes.

COMMERCIAL SUPPORT

ProPymes assists suppliers in the development of new products for Ternium and/or any of its affiliated companies. In addition, it assists SMEs in the development process required to become a supplier of large companies to gain new customers for automotive,

oil & gas and other industrial sectors.

ProPymes also offers SMEs the possibility to leveraging on the Techint Group's global network of commercial offices in order to enhance their market reach.

FINANCIAL ASSISTANCE

The financial assistance services aim at fostering investments to enhance productivity and increase SMEs' installed capacity. The scope of ProPymes assistance includes the development of the project, its budget and the application for commercial bank financing or government-sponsored low-cost financing instruments. Since its creation, the program has helped obtain financing or financed projects of Ternium's customers for an amount of $123 million.

Advancing the SMEs Agenda

SMEs making up Ternium’s value chain are key players

for the social integration of their communities, as they generate a substantial share of total industrial jobs

in Latin America. The ProPymes program plays an important role in advancing the SME policy agenda

in Mexico and Argentina.

In Mexico, the ProPymes biannual event showcases awards for SMEs excelling in areas such as industrial safety, logistics services, delivery, raw material handling and other services. The occasion also includes a Supplier of the Year award. In Argentina, the event features several panels designed to allow SME executives share their experiences and lessons learned.

ECOSISTEMA PYME

Since 2017, the Argentine government sponsors the Ecosistema Pyme program, or SME Ecosystem,

which considers the ProPymes program a model to be replicated by other large companies in the support

of their sector's value chain.

In Argentina, the stories of SMEs that are part of Ternium’s ProPymes program appeared in video-narrations published in the web platform of one of the country’s largest media groups and have been widely circulated on social media. Different companies owners were featured sharing how their enterprises started and grew, the difficulties they had to overcome, and the potential they envision for the future.

Our community programs reflect over seven decades of the Techint Group's worldwide industrial tradition. The principle guiding our work is that an industrial project like ours can only be sustainable if community and industry grow together. In recent years, we have concentrated our community action on four main areas: education, culture, volunteer work and health. Our strategic programs were designed to be implemented at local level, taking into account the particular circumstances of each community where we operate.

We believe that education is the key to prosperous community growth and have developed educational programs covering the entire school cycle, from elementary to higher level, helping all children to fulfill their potential and become active contributors to society. In 2019, 70% of our $6,6 million community relations budget was invested in education.

As a multi-cultural and multi-lingual company, we enrich and broaden people’s cultural horizons in the communities where we work, fostering diversity and inclusion by promoting cultural activities.

We encourage our employees to volunteer for community activities aimed at helping those in need,

with a special focus on refurbishing schools, as a way of cultivating pride and integration in our communities.

With the aim of improving people's life quality and fostering welfare, we support health care initiatives mainly by funding improvements in the health care infrastructure of Ternium's communities. More recently, Ternium launched a special $5.5 million funding program to strengthen health care infrastructure to face the COVID-19 outbreak at its communities in Mexico, Argentina, Brazil and Colombia.

Developing High Standards of Technical Education

The Roberto Rocca Technical Schools program (ETRR, for its acronym in Spanish), which operates purpose-built schools, was launched to educate high school students from our communities using innovative teaching methods and the latest technology in both classroom and laboratory. The schools, named after one of the company’s founders, is dedicated to promoting technical education and enterprise, offering students different levels of scholarships, depending on their needs.

In 2019, both schools saw their first classes graduate after three years of study in Mexico and seven years in Argentina. Many of these students are the first in their families to finish high school and go on to university. Like their peers in European countries, ETRR Pesquería students receive 1,600 hours of teaching per year, as well as more than 600 hours of industrial internships.

In order to help students develop Industry 4.0 skills, we have adapted the Maker project-based-learning teaching methodology to encourage them to think in different ways, fostering innovation and teamwork, as well as other personal abilities including critical thinking and communication skills. In 2019, we trained 15 teachers to use this methodology; students produced 97 projects they subsequently exhibited, putting some into practice to benefit their local communities. ETRR students participated in the World Educational Robot Contest (WER) with one team participating at the international finals in Shangai, China.

We believe that academic excellence is fostered by gifted teachers who are truly committed to both students and the community. In 2015, the ETRR pioneered in Argentina a comprehensive teacher performance assessment system, involving student surveys, on-the-ground class observation, and school committee evaluation. The ability to benchmark and guide improvement is the cornerstone of our teacher development plan, which rewards performance, attendance, the use of technology and training.

During 2019, 23 teachers were evaluated and 3,777 training hours were provided in Mexico as part of their continuous development.

In October 2019, during the annual worldsteel assembly in Monterrey, Mexico, Ternium received

the Steelie Award for “Excellence in Education and Training” on account of the work done in the Pesquería ETRR. As creativity and self-expression

are essential to our students’ all-round development, we organized the second Literary Contest for the Roberto Rocca Technical School's network as part

Quality Education for the Communities

Ternium has different programs aimed at improving skills and education in developing communities near its facilities. We organize workshop academies in Pihuamo, Aquila and Alzada in Mexico. In addition, through the AfterSchool program, we provide support to primary schools in San Nicolás de los Garza, Mexico, and in Ramallo, Argentina. The AfterSchool Program was designed for communities with considerable school dropout rates. Last year, in the two countries hosting the program, 270 children aged between six and twelve enrolled in these activities.

Focused on STEM subjects (Science, Technology, Engineering, Math), the program offers primary school children extra hours of quality education four days a week to encourage them to commit to learning and further their personal development in the longer term. During 2019, we strengthened the AfterSchool model with new maths content and related project-based learning methodologies. After just one year, the results showed students had improved their maths skills from those of a low level at a low-performing school to the

Participants not only improved their maths abilities but also developed other life skills and a sense of purpose after attending the program for several years: 84% of students improved their perseverance, 83% improved critical thinking, and more than 75% are keen to pursue STEM careers.

Encouraging Excellence Among High-School Students

Launched in 1976 in Argentina, the Merit Awards program was initially designed to benefit the children of Ternium's employees but has long since been extended to the wider community. It focuses on stimulating academic performance and commitment among high-school students living in our communities.

In 2019, we awarded 759 scholarships to outstanding students in six countries, including Brazil for the first time. In addition, we launched a pilot project in Brazil, for eligible students, for the on-line application to 60 high-school scholarships.

Roberto Rocca Education Program

The Roberto Rocca Education Program awards fellowships and scholarships to promote engineering and applied sciences studies at undergraduate and graduate level in countries where we have a major presence. In 2019, the program funded 15 fellowships for students pursuing for their PhDs at universities outside their country, and 305 scholarships for undergraduate students at universities in their home countries. In addition, the program was implemented for the first time in Rio de Janeiro, Brazil.

We also reinforced our relationships with universities based in the UK, The Netherlands and Germany, with two PhD fellows currently carrying out their industrial practices at our R&D centers and five visits from other PhD fellows. In addition, we held three webinars and are pursuing quarterly follow-up activities with each university.

In 2019, approximately 4,000 runners participated in the 15th edition of the 10K Ternium in San Nicolás, Argentina; 5,000 runners participated in the 11th edition of the race in Monterrey, Mexico; 1,500 runners participated in the 8th edition of the race in Colima, Mexico; 1,200 runners participated in the 2nd edition of the race in Rio de Janeiro, Brazil; and 1,200 runners participated in the 2nd edition of the race in Villa Nueva, Guatemala.

In addition, we organize sport leagues involving schools in neighboring communities. Regarding health care initiatives, the company supports and funds a basic health care unit in Aquila, Mexico, and funds improvements in health care infrastructure in different countries. In addition, we organize health fairs, clinical examinations, and disease and addiction prevention campaigns.

SPECIAL FUNDING PROGRAM FOR COVID-19 OUTBREAK

In response to the COVID-19 outbreak at the end of

2019, we designed a consistent reinforcement plan together with the directors of key hospitals in each of Ternium's communities. The plan considered the age

of the local population and the availability of health care infrastructure, such as intensive care units (ICUs) and protective gear, among other medical equipment. In Monterrey, Mexico, Ternium has built in record time and is operating a field hospital, taking advantage of the operations of Clínica Nova, the company's local health care unit. The field hospital has 100 beds and 10 ICUs for people without health insurance.

In Rio de Janeiro, Brazil, the company has supplied 25 ICUs and ventilators to two local hospitals, and has partnered with Senai, a national network of technical schools, to repair out-of-use ventilators from local hospitals. In Ensenada, Argentina, Ternium supplied 100 beds to a field hospital. The company also supplied ICU equipment and protection gear for doctors. All-in-all, more than 90 ventilators, 1,700 medical equipment and 170,000 safety kits for health professionals were donated to 14 hospitals and health care facilities in four countries.

In addition, Ternium manufactured face masks at its

facilities and in the ETRR for doctors and first responders. Furthermore, the company offered support to local entrepreneurs for manufacturing ventilators, and to hospitals for adapting their facilities.

To foster the sharing of knowledge on treating COVID-19, we created a network of medical professionals alongside our sister company 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 is available at a public virtual campus.

Alongside the Fundación Hermanos Agustín y Enrique Rocca (Agustín y Enrique Rocca Brothers Foundation), and Tenaris, Ternium contributed 20,000 boxes of food for vulnerable families through the #SeamosUno project in Argentina. In addition, Ternium provided food support for 446 families of children participating at its education programs in Rio de Janeiro, Brazil, and for 44 families of students at the ETRR in Pesquería, Mexico.

Our articles of association provide that our annual ordinary general shareholders’ meetings shall take place in Luxembourg, or in a foreign country whenever circumstances of force majeure take place, within six months from the end of the previous financial year. There are no limitations currently imposed by Luxembourg law on the rights of non-resident shareholders to hold or vote the Company’s shares.

The Company’s Board of Directors is currently comprised of nine directors (eight male and one female). Four directors are independent under the articles of association and SEC regulations applicable to foreign private issuers. The Board of Directors has an Audit Committee consisting of three independent members. The charter of the Audit Committee sets forth, among other things, the Audit Committee’s purpose and responsibilities, which include the responsibility to review material transactions with related parties to determine whether their terms are consistent with market conditions or are otherwise fair to the Company and/or its subsidiaries. In addition, the Audit Committee reports to the Board of Directors on the adequacy of the systems of internal control over financial reporting.

Ternium has adopted a Code of Conduct incorporating guidelines and standards of integrity and transparency that apply to all directors, officers and employees. The Code of Conduct is periodically reviewed to bring it up to date with the latest trends and incorporate new provisions, if applicable.

In addition, the company has adopted a Code of Ethics for Senior Financial Officers, 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 Human Rights Policy and a Policy on Diversity and Work Environment Free of Harassment.

All members of Ternium's Board of Directors, all of its senior managers and 99.7% of its white collar employees (salaried employees and managers, excluding hourly employee supervisors) have acknowledged and committed to abide by its Code of Conduct and Policy on Business Conduct.

Ternium has an Internal Audit area that reports to the Chairman of the Board of Directors and, with respect to internal control over financial reporting, to the Audit

81. Sustainability Report 2019

Commitment to Integrity

Committee. The Internal Audit area evaluates and reassures the effectiveness of internal control processes, risk management and governance.

Risk Management

Ternium has an established process of risk identification and management. At the helm is the company's Critical Risk Committee (CRC), which assists the CEO on the subject. While management is responsible for identifying and managing risks, the CRC facilitates the identification and assessment of critical risks, the development of mitigating actions and the monitoring of action plans. Critical risks are escalated through the usual reporting lines and decision-making is the responsibility of managers.

The CRC focuses on risks considered critical to the company’s assets, operations or reputation. Ternium has categorized risks according to the potential area impacted, the likelihood of their occurrence and the severity of an eventual impact. The main identified risks include major accidents impacting our operations, cybercrime and environmental accidents. Recently, the

CRC has focused its attention on the main actions and

mitigation plans to tackle the consequences of the COVID-19 outbreak to ensure business continuity.

Business Conduct Compliance Program

Ternium has developed a Business Conduct Compliance Program with the objective to prevent and mitigate bribery and corruption risks. The Compliance Program involves white collar employees and is aimed at promoting the implementation of best practices in business conduct internally and also regarding the relations with customers, suppliers, state-controlled entities and other third parties.

Ternium has appointed a Business Conduct Compliance Officer reporting to the CEO of the Company, who has responsibility for identifying and mitigating corruption risks and fostering a culture of ethical and transparent conduct, and for designing, implementing and supervising the Compliance Program aligned with the requirement of applicable national and international laws against corruption and bribery, such as the US Foreign Corrupt Practices Act (FCPA).

Code of Conduct for Suppliers. Ensuring that governance standards are in place, including ethics, health, safety, human rights and environmental stewardship commitments.

82. Ternium

All members of Ternium's Board of Directors, all of its senior managers and 99.7% of its white collar employees have acknowledged and committed to abide by its Code of Conduct and Policy on Business Conduct as of December 31, 2019.

The Business Conduct Compliance team has local presence in the main locations where the company has businesses. The Business Conduct Compliance Program is focused on preventive measures like risk assessment, normative design, communication, advisory, training, certification, monitoring and auditing, including third parties. The function also includes disciplinary actions, remediation and benchmarking. Activities are implemented based on a periodic risk assessment that enables us to identify key factors to be stressed on, particularly at training and risk prevention sessions, based on the employees' likely exposure to conflicting situations. Consequently, only white collar employees participate in the program, while hourly employees and their supervisors are excluded.

Ternium’s Code of Conduct and Policy on Business Conduct clearly define that any corrupt payment is strictly prohibited and will not be tolerated; they also include specific guidelines regarding due diligence when hiring third-parties that act on behalf of Ternium. Charitable and political contributions, as well as hospitality expenses to third parties (meals, gifts and business trips) are regulated by internal procedures. Facilitating payments are forbidden. Communication is essential to build an ethical culture.

Ternium maintains regular communications with its directors, senior managers and employees in order to raise their awareness and keep them alert on possible corruption risks, and to remind them of the applicable principles and regulations. This program includes top-down messages, management meetings, newsletters, articles and announcements on the company's intranet.

The company encourages active participation of all areas, emphasizing the importance of asking for guidance in case of red flags or ambiguous situations.

Ternium has defined specific procedures for hiring professional services providers that act on behalf of or otherwise represent the company before governmental entities, including those retained to assist in obtaining permits or licenses, customs brokers, advisers and law firms. These procedures include a due diligence process, internal authorizations and contract provisions to ensure third-party’s commitment to Ternium’s anti-bribery policies.

Monitoring procedures and audits are carried out regularly to validate the effective implementation of the Compliance Program and the investigation of any conduct contrary to the Policy on Business Conduct or its principles.

Training Program for Third-Party Employees. Ternium's anti bribery training program also reaches third parties that represent or act on behalf of the company.

Training on Anti-Bribery Policies and Procedures

Ternium has implemented an extensive training program on anti-bribery policies and procedures for its white collar employees. This program enables the company's senior management to engage the

organization behind Ternium's ethical commitment, with a clear set of guidelines and by sharing their values. All white collar employees participate in an on-line mandatory training program and, according to their level of exposure, in an on-site training program as well. 98.2% of Ternium's white collar employees have completed the mandatory training course on the company's Policy on Business Conduct in e-learning format. In 2019, Ternium delivered 64 on-site training sessions to 878 employees in Mexico, Argentina, Brazil, Colombia and Guatemala.

Our anti-bribery training program also reaches third parties that represent or act on behalf of Ternium. 325 third-party employees have completed Ternium's mandatory training program on corruption prevention, which has been implemented in e-learning format.

Code of Conduct for Suppliers

Ternium purchases most of its supplies through Exiros, a specialized procurement company whose ownership we share with Tenaris. Ternium’s suppliers undergo, through Exiros, a rigorous process of selection to ensure governance standards are in place, in line with applicable laws and regulations and our Code of Conduct for Suppliers, which includes, among other items, ethical behavior, compliance with the law, and health, safety, human rights and environmental stewardship commitments.

Compliance Line

Ternium established and encourages the use of a web-based confidential Compliance Line. The company’s compliance line serves as a channel for confidential communication and is available to all employees, suppliers, customers and other stakeholders who wish to report all types of alleged breaches of the Code of Conduct and its principles. Ternium's Compliance Line is available in Spanish, Portuguese and English.

84. Ternium

A Transparency Policy governs the relationships with third parties.

Both the identity of the individual who reports an issue as well as the issue itself are treated in a strictly confidential manner, to the extent permitted by relevant legislation. Anonymous reporting is also possible. Internal Audit, which is independent from all operational areas, analyzes all reports received and is supervised by the Audit Committee for issues related to financial reporting.

Ternium implements the necessary actions to avoid retaliation against those who use the Compliance Line in good faith. In 2019, 46% of analyzed complaints ended up in disciplinary actions, including dismissals and termination of commercial relationships. The reports have also helped to improve the company’s internal control environment. Although complaints can be anonymous, in 52% of cases the complainants have identified themselves.

Ternium's Sustainability Report for the year 2019

follows the core option of the reporting levels of the Global Reporting Initiative standard.

Materiality Analysis for Ternium's Sustainability Report

Ternium's sustainability report’s content was redefined according to the Global Reporting Initiative (GRI) principles of Stakeholder Inclusiveness, Sustainability Context, Materiality and Completeness. A Materiality Analysis was carried out according to the GRI four-step process that an organization may go through in order to define the document’s specific content.

Key economic, social and environmental topics were identified through a combination of industry research and benchmarking, international standards and priority subjects (Identification), and then prioritized through a stakeholder consultation process that compiled a total of 1256 responses from employees, suppliers, customers, community organizations, business associations, investors, press, and academic institutions (Prioritization). To conclude the selection of material topics, the results were examined considering the company’s long-term strategy and the programs implemented, resulting in a Materiality Matrix that combines both perspectives (Validation).

MATERIALITY MATRIX

The Materiality Matrix in the following page presents the economic, environmental and social topics that were defined as a priority to include in our 2019 Sustainability Report. They are informed according to GRI Standard core option of the reporting levels throughout the document and, in order to facilitate access, indexed in the following sections.
