Following an exceptional 2021, 2022 was another good year for Ternium as it navigated a highly volatile geopolitical and economic landscape in our region and at a global level. The war in Ukraine, rising inflationary pressures, the gradual slowdown in the global economy, as well as the economic instability in Argentina, created a challenging environment for our company.

In spite of these challenges, Ternium posted solid financial results for the year, with an EBITDA of $3.4 billion and net income of $2.1 billion on shipments of 11.9 million tons. Net sales were similar to those of 2021 despite slightly lower shipments, reflecting the benefits of integrating slab production in Brazil with finished production in Mexico. Free cash flow was particularly encouraging at $2.2 billion and we accumulated a net cash position of $2.6 billion by the end of the year. A dividend of $2.70 per ADS was approved for the year.

Despite the ongoing global uncertainty, we are moving forward with our agenda of growth and sustainability. Ternium, with its solid financial and unique industrial and commercial footprint, is well positioned to grow as a supplier of high quality steel products for the industrial sector throughout the Americas and to support nearshoring and industrial development opportunities.

Earlier this year, we announced significant investments which will continue to transform Ternium in the years ahead. Over the next three years, we will invest $2.2 billion in electric arc furnace (EAF) steelmaking and direct reduction of iron ore (DRI) facilities with a capacity of 2.6 million tons per year of steel slabs and 2.1 million tons per year of DRI. This investment will complete the integration of our flat-rolled steel production operations at Pesquería, Mexico, and will complement the ongoing expansion of our high value added production capacity in cold rolling, galvanizing and additional advanced finishing lines, including the expansion of our R&D center.

The investment in Pesquería is aimed at (i) strengthening our capabilities to supply Mexico’s industrial sector with its opportunities for growth due to the nearshoring of industrial supply chains, (ii) meeting “melted and poured” requirements under the USMCA trade agreement, and (iii) advancing towards our 2030 decarbonization target.

Ternium is already a steel producer with a relatively low level of CO2 emissions intensity, and is fully committed to further advance towards the decarbonization of its operations and to reducing their environmental footprint. Renewable energy is an important element in our decarbonization strategy and we are targeting to source 40% of our purchased electricity requirements from renewable energy as part of our 2030 decarbonization target. This year we will be investing $160 million in a wind farm in Argentina, which will supply 65% of our requirements


6. TERNIUM_SUSTAINABILITY REPORT 2022
CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY






for purchased electricity in the country. We expect the wind farm to begin operations in the second half of 2024.

This month, we increased our investment in Usiminas by acquiring part of the participation held by Nippon Steel Corporation in the Usiminas controlling group. As a result of this transaction, we now hold 51.5% of Usiminas’ control group, which holds the majority of the company’s voting rights, with the right to nominate the CEO and a majority of the Board of Directors, and 25.1% of the total shares. With our increased involvement in the company’s management, we aim to increase Usiminas’ competitiveness and strengthen its position in the Brazilian flat steel market.

Combining our strong regional presence in the Americas, and our downstream capabilities for producing the most value-added products, we are in a unique position for supplying the needs of the manufacturing, construction, and energy sectors in a region that should play a key role in the repositioning of the global supply chain in the coming years.

Although our performance in safety has been recognized by worldsteel and most of our safety indicators have improved, with our lost time injury frequency rate falling to its lowest ever level, we deeply regret that three fatalities occurred in our operations over the past 12 months. These events have led us to question deeply all our procedures, actions and training activities to ensure that safety is prioritized above all else throughout our operations, that our people have the training and tools to proactively reduce risks and prevent hazards, and that everyone is encouraged to identify opportunities for improvement.

We are increasing our investment in education programs for the communities around our plants with the decision to build a Roberto Rocca Technical School in the community of Santa Cruz, Rio de Janeiro, where we have our Brazilian slab-making facility. The new school will complement the existing Roberto Rocca Technical Schools in Pesquería, Mexico and in Campana, Argentina. By establishing beacons of excellence and leveraging network effects, we are contributing to improve standards in technical schools widely across our communities as well as encouraging local students to fulfil their potential independently of their means.

In this report, you can learn more about how Ternium embeds sustainability principles in all aspects of its management. This stems from the long-term vision of our founding shareholders and a resolute focus on strengthening the positioning and competitiveness of our operations.

The concept of sustainability has been an integral part of our strategy for many years. At its core, it encompasses the principles of technical and operational excellence, as well as the preservation of people's safety. Safety is our primary value and extends to all those who perform roles within our facilities. To achieve these objectives, Ternium relies on the talent of its employees, and our efforts are focused on developing that potential, which is diverse and rich due to the multicultural nature of the countries in which we operate and are at the origins of our company.

We are thrilled to embark on a new phase of development with the Pesquería Industrial Center project at its base, representing the convergence of our vision for the future of the industry. The new DRI-EAF steel shop will be equipped with the latest technologies to accelerate Ternium's ongoing commitment to decarbonize its operations, including carbon capture capabilities and readiness to switch from natural gas to hydrogen for DRI production. In addition, all water utilized in the new facility’s production process will be sourced from wastewater treated for industrial use.

Our growth must be in harmony with the development of our communities, and education plays a key role in this aspect. In line with this commitment, we are strengthening our educational programs by building a new technical school in Santa Cruz, Brazil, and enhancing our existing programs to create more opportunities for all.

10. TERNIUM_SUSTAINABILITY REPORT 2022
CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
Ternium is a flat and long steel producer with a strong presence in the Americas. Ternium’s facilities are located in Mexico, Brazil, Argentina, Colombia, southern United States, and Central America. Additionally, the company is taking management responsibility over Usiminas, a leading flat steel manufacturing company in the Brazilian market, by increasing its participation in the company's controlling group.

Ternium has grown along a strategy mainly based on organic investments and acquisitions, consolidating its regional markets by seeking import substitution and expanding its commercial presence. As growth accelerated, Ternium broadened its product offerings and developed more sophisticated products to meet increasingly demanding markets, including the need for high-strength and ultra-lightweight steel for the automotive industry.

At the heart of our current growth strategy is our Industrial Center in Pesquería, Mexico. Built from the ground up and fully based on a sustainability philosophy, the Pesquería Industrial Center combines the latest technological developments to achieve efficient, high-quality production with a strong focus on people's safety along with an environmentally conscious approach.

The recently announced upstream capacity project will enable the company to better meet industry needs and
will be equipped with CO2 capture modules as well as the possibility of using green hydrogen when market conditions permit, allowing Ternium to further advance its decarbonization roadmap.

On this topic, in 2021, we set a medium-term goal to reduce our emissions intensity by 20% by 2030 compared to the 2018 baseline (scopes 1 and 2) along with a clearly defined roadmap based on six fundamental axes: energy efficiency; the use of renewable energies; the development of new raw materials in collaboration with business partners to replace coal and traditional iron ore pellets; the use of low-emission technologies; the expansion of CO2 capture and utilization capacity in existing plants, along with an increase in the use of scrap in the metal mix. We are also exploring other initiatives as part of our ambition to achieve carbon neutrality.


It is to be noted that all these initiatives have been feasible mainly thanks to the diverse talent we have fostered in our company over the years. Ternium is committed to developing its human capital, retaining talent, and ensuring equity among those who work within the company.

Sustainability is not a new topic for Ternium. ProPymes, the company’s support program for small and medium-sized suppliers and customers, has been in place for over 20 years. This program reflects our interest in growing together with our business partners and creating a resilient value chain even in times of adversity, such as the 2001 crisis in Argentina, when this program was created. Additionally, we continue to advance in our community growth programs, primarily focusing on education as a driver of change and social mobility.

Ternium reports to international agencies about its management approach and performance metrics on different Environmental, Social, and Governance (ESG) issues. In 2022, Ecovadis, a provider of business sustainability ratings, ranked Ternium within the 90th percentile in the "Manufacture of basic iron and steel" industry based on our policies, procedures, and actions related to environmental and labor practices, sustainable procurement and ethics. We also report to the Carbon Disclosure Project (CDP), an international non-profit organization that runs a global environmental disclosure system, on specific climate-change-related issues. In 2022, CDP rated Ternium with an A- in its Climate Change questionnaire thus including the company in the leadership category. This includes demonstrating adherence to best practices for strategy and action outlined in frameworks like the TCFD (Task Force on Climate-related Financial Disclosures).

Ternium has been acknowledged as a Sustainability Champion by the World Steel Association for five consecutive years and was recognized with the Steelie Award 2022 in the "Excellence in Education and Training" category. These relevant acknowledgments validate the company's commitment to sustainable growth and continuous improvement.

CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY

STRENGTHENING TERNIUM'S PRODUCTION SYSTEM:
STRONG PRESENCE IN THE AMERICAS

Ternium’s goal is to increase value for stakeholders
by further consolidating its position as a top steel producer in Latin America and a prominent player in the Americas. Its business strategy consists of three key
elements: actively seeking growth opportunities, emphasizing the production of high value added products, and continuously striving for efficient and competitive industrial operations.

The company has a track record of strategic business
growth through acquisitions and organic expansion. In
Mexico, its primary market, Ternium initially acquired
two large industrial companies: Hylsamex and Grupo Imsa in 2005 and 2007, respectively. In 2013, Ternium established the Pesquería Industrial Center, a state-of-the-art greenfield project focused on advanced technology and sustainability. This expansion facilitated the company's diversified steel product portfolio, particularly for the automotive sector.

During the last twenty years, the Mexican market has
experienced significant growth, mainly driven by a dynamic manufacturing industry. According
to worldsteel’s data, apparent steel consumption in
Mexico increased at an average compound annual growth rate of 3% between 2000 and 2022. Moreover, the composition of steel supply in the country has created opportunities for import substitution.

In this context, Ternium made a series of investments
to strengthen and consolidate its presence in Mexico.
The first investment addressed the insufficiency of slabs production in Ternium´s industrial scheme in Mexico, given the higher downstream installed capacity. In 2017, Ternium acquired a slab mill in Rio de Janeiro, Brazil, with a production capacity of 5 million tons per year. This acquisition increased the company's total crude steel production capacity by approximately 70% to 12.4
million tons. Currently, the main destination of Brazilian slabs is the Pesquería facility in Mexico and a small portion is sold in the Brazilian market.

SINCE INAUGURATION OF PESQUERÍA
INDUSTRIAL CENTER IN 2013






Ternium’s second investment focused on expanding
its product range and incorporating higher value added
products to cater to a more demanding market. In 2021, the new advanced hot rolling mill in the Pesquería Industrial Center started operations and we built a research and development center to support the manufacturing activity. This has led to a significant reduction in testing and certification time for highly specialized industries, including the automotive sector.The complete project includes other downstream facilities like a push-pull pickling line, a cold-rolling mill, a hot-dip galvanizing line and finishing lines, which are slated to begin operations in 2024 and 2025.

Recent developments have prompted a reevaluation of the Pesquería Industrial Center's capabilities, leading to further enhancements. As an example, the rule of origin of the USMCA (United States-Mexico-Canada Agreement) trade agreement, states that duty-free trade in the automotive sector is only available for goods that can be considered as originated from anyone of the member countries starting from 2027.

tx_sr2022xterniumstrategyxi.jpg
Pesquería New Hot Rolling Mill - The process of coil formation is carried out through hot rolling equipment.
As a result, in early 2023, Ternium announced the
construction of a new steelmaking facility comprising
an electric-arc-furnace-based steel shop, a DRI
module and a port. These facilities are set to produce high quality steels required for demanding applications, particularly in the automotive industry. The project is scheduled to commence operations in 2026, significantly increasing the company´s competitive position in the Mexican market. Notably, the new DRI module will incorporate carbon capture capabilities and be adaptable for transitioning from natural gas to hydrogen use when feasible, aligning with Ternium’s medium-term decarbonization goals.

As the market grows and trends like the nearshoring of the steel value chain emerge, Ternium reinforce its commitment to the industry by delivering high-quality steels and enhancing its commercial services.

Ternium strengthens its presence in Latin America

Ternium’s objective is to identify and pursue strategic opportunities for growth, enabling the company to strengthen its position in key markets throughout the
Americas. The focus is on enhancing its industrial system integration across operations in Mexico, Brazil, the US, Argentina, Colombia, and other countries. This involves broadening the range of value-added products and improving its production and distribution capabilities.

In Argentina, Ternium is the leader in the country's flat steel industry, which is the third largest in Latin America. With manufacturing customers accounting for around half of the local flat steel consumption, there are ample opportunities to offer value-added products and services. Through initiatives like the ProPymes program, the company has fostered strong connections within the local industrial cluster and supported the growth of medium and small enterprises, positioning itself favorably in the competitive landscape.

In Colombia, the fourth largest steel market in Latin
America, Ternium has expanded its capacity by
establishing a reinforcing bar facility in Palmar
de Varela in 2020. Additionally, the company owns finishing lines and service centers in Guatemala,

INGREASING OUR PARTICIPATION
IN THE USIMINAS CONTROL GROUP
In March 2023, Ternium announced an agreement with Nippon Steel to acquire a portion of its stockholding, thus increasing Ternium’s stake in Usiminas’s control group.

The Usiminas control group holds the majority of the company's voting rights. With the recent closing of this transaction, Ternium now holds an aggregate participation of 51.5% in the control group. The Usiminas control group has also agreed a new governance structure. Ternium and its related companies will nominate a majority of the Usiminas board of directors, the CEO and four other members of Usiminas board of officers.

Usiminas is one of Brazil’s major producers of flat steel products, including iron ore mining, steel production, and steel processing and customization. In 2022, Usiminas shipped 4.2 million tons of steel products, of which 86% were directed to the Brazilian market, and 8.6 million tons of iron ore, with total net sales of BRL 32.5 billion.

With its industrial footprint, network of distribution centers and commercial offices, Ternium is well equipped to offer differentiated logistics and stock management services. This gives the company a competitive advantage in major steel markets.


DELIVERING SOPHISTICATED STEEL PRODUCTS

Ternium’s product development roadmap aims to increase the participation of higher margin value added products in the sales mix, with a special focus on the expansion of Ternium’s offering of resistant and lightweight steel products for low carbon economy applications.

The start-up of the new hot-rolling mill in 2021
represented a technological leap forward in Ternium Mexico’s steel production capacity and strengthened
its positioning in the high-end market sector. In this
sense, the development of substrates for galvanized top quality exposed parts with very high drawability requirements was one of the milestones achieved during the first months of operation of the new hot-rolling mill.

In 2022, the company intensified the product development activities to expand its high-end product portfolio for customers in the automotive, metal mechanic, home appliance, energy and electric motors industries. During the year we completed the design of new substrates to replace some of the hot-rolled steel products procured from third parties. This development will allow Ternium to become fully compliant with the new USMCA rules of origin in connection with the supply of galvanized products to the automotive industry. We also developed new hot-rolled steel products prototypes for the automotive industry to replace imported material. This industry holds a significant share in Ternium's shipments in Mexico, representing 24% in 2022.

Ternium also launched innovative coated steel coils that combine eco-friendly materials with energy-saving solutions for the construction sector. The company expanded its product range by developing coiled plates up to one inch, catering to the needs of the structural steel market.

Moreover, the company advanced its project to incorporate co-laminated finishing to its product offering. This new technology will enable us to offer steel products with superior aesthetic attributes for architectural and appliances designs. We are undergoing the product certification process and expect to start production soon.

Additionally, new features were introduced to the pre-painted products for motor casings, with the potential for implementation in home appliances. These new features provide new coating types that closely resemble stainless steel.

In 2022, Ternium made further investments to strengthen its R&D infrastructure. The second phase of the R&D project in Pesquería, Mexico was launched, and advanced electronic microscopes were installed in the laboratories of Argentina and Brazil. This allowed the company to bring the microscopy service in-house, previously outsourced to third parties. As a result, Ternium was able to accelerate optimization efforts in steelmaking operations, with a focus on producing environmentally friendly steels and ensuring the reliability of its products.

Ternium forms strategic partnerships for joint research

Ternium’s in-house research activities are complemented by its involvement in a global network of industry consortia, universities, and research centers. One notable example is its membership in WorldAutoSteel, an organization comprising major steel producers worldwide. Ternium actively participated in the engineering core team of the Steel E-Motive project, sponsored by WorldAutoSteel, in the design of cost-effective, safe, and sustainable autonomous and connected electric vehicles using cutting-edge engineering and advanced high-strength steel technologies.

Additionally, Ternium partners with universities on joint initiatives, fostering the involvement of researchers and students from prestigious institutions in early-stage development projects.

The company also collaborates in providing technological assistance to related companies. In 2022, we initiated an important project to improve the operation and maintenance of a related company´s blast furnaces in Brazil, extending our best practices.


COMPETITIVENESS AGENDA: SMART FACTORY

SMART is the acronym for Social, Mobile, Analytics, Robotics and (internet of) Things. Ternium is making progress in the deployment of new digital technologies that are leading to step improvements in its operating performance. These new solutions are based on the processing and analysis of a constant stream of information and knowledge from Ternium’s industrial operations (data and events provided by meters, cameras and drones).

In order to support Ternium’s analytics needs across
all business functions, the company has implemented a
Data Lake, a single technological platform that meets
all the company’s big data and analytics requirements.
SMART factory applications include a wide array
of company functions such as order management,
administration, human resources, maintenance,
quality, and occupational health and safety. Solutions
encompass mobile and remote work; remote assistance
(augmented reality); personnel training (virtual reality
simulation); the execution of automated administrative
processes and tasks (robots); and the real-time
autonomous detection of unsafe conducts or situations,
the autonomous assessment of difficult-to-access
building structures and equipment, and the appraisal
of bulk material (automatic image interpretation
through artificial intelligence).

SMART factory applications also include the automated handling of steel products in the yards (RFID and WMS), and the prediction of failures in maintenance management (predictive analytics and data correlation). Ternium’s RFID system has been installed at several stockpile yards for identifying and tracking each coil from the moment it reaches the yards up to shipment, facilitating inspection procedures, improving inspectors’ safety and reducing operations lead times.

The slab continuous casters at the company’s Brazilian, Mexican and Argentine facilities use analytics and data correlation technology for maintenance purposes. The plan is to extend this technology to the company’s main flat steel hot-rolling, cold-rolling and galvanizing lines to shield strategic equipment and reduce interruptions, thus increasing the reliability of operations while lowering costs.

In 2022, the company's supply chain and systems teams developed a logistics center at the San Nicolas plant in Argentina, allowing real-time tracking and generating early alerts that enable timely decision making. The logistics center facilitates transport planning and real-time tracking of logistics execution, optimizing the use of warehouses and trucks.

Technology is present in all aspects of Ternium’s business, and one of the most significant and long-term impact activities is training. Among the most important objectives of using IT tools in training activities are the reduction of accident rates by reproducing high-severity incidents, improving work team performance by simulating everyday tasks and the tools used and by simulating the behavior of the main production lines to improve operating conditions or achieve new products in a controlled environment prior to industrial testing.

DEVELOPING A SUSTAINABLE
EXPORT SOLUTION


Ternium has undertaken a project aimed at improving operations and reducing environmental impact in the export of slabs from Brazil to Mexico. This collaborative effort involved Ternium’s Global Logistics team in Uruguay, as well as the Supply Chain teams in Mexico and Brazil.

The key component of this initiative was the installation of cranes equipped with magnets at the port of Brownsville, USA.

These cranes facilitate the efficient unloading of Ternium Brazil’s slabs, which are then transported to Ternium’s Industrial Center in Pesquería, Mexico.

The implementation of this process has resulted in a significant reduction in the use of wooden dunnage for cargo securing.

As a result, approximately 26,700 trees are saved each year, leading to both environmental benefits and increased operational productivity.

SUSTAINABLE PROCUREMENT

While Ternium handles slab procurement directly,
the centralized procurement of raw materials and
industrial services is entrusted to Exiros, a company
established jointly with our related company, Tenaris.

By utilizing the combined purchasing power of both
companies, Exiros has built an extensive network
of suppliers, with nearly 49,000 registered and over
15,000 active vendors in 2022. Among these, 7,300
suppliers specifically cater to Ternium’s requirements.
The procurement services offered by Exiros are
certified under the ISO 9001 standard, ensuring a high
level of quality.

When evaluating suppliers, Ternium insists that all its business partners adhere to the same rigorous standards that the company upholds. These standards encompass ethical conduct, legal compliance and the fulfillment of health, safety, and environmental obligations. Alongside the Supplier Code of Conduct, Ternium has recently introduced a Sustainable Purchasing Policy to further engrave its dedication to sustainability throughout the supply chain. Ternium will actively oversee the implementation of these principles, either independently or with the assistance of third parties, as determined by the nature of the business relationship and its impact on Terniums operations.

Additionally, Exiros carries out yearly audits to
evaluate the health and safety practices of its suppliers.
These audits serve as a prerequisite for awarding or
renewing service contracts, and they play a crucial role
in long-term risk management. As of December 2022,
Exiros has successfully audited and certified 94% of its active service suppliers, who were classified based
on a rigorous criterion pertaining to health, safety,
and environmental risks. The audit process follows
Ternium’s standardized self-assessment procedure,
which has been specifically tailored for suppliers offering services. In 2022 alone, a total of 525 new audits were conducted.

THE ROLE OF THE STEEL INDUSTRY IN ADDRESSING CLIMATE CHANGE

Steel has played a critical role in shaping modern economies and societies. Its strength, versatility, and durability have made it a fundamental component in modern civilization, from buildings and bridges to cars and household appliances. However, the steel industry is also a major contributor to greenhouse gas emissions, accounting for 7% to 9% of global anthropogenic CO2 emissions according to worldsteel figures. As the world seeks to transition to a low-carbon economy and mitigate the effects of climate change, the steel industry faces the significant challenge of reducing its carbon footprint while attending to the likely increase in global steel demand.

In this context, one of the main challenges in decarbonizing the global steel industry has to do with the fact that most of its production processes heavily rely on coal and other fossil fuels. Currently, close to 71% of global steel production is made through the blast furnace route, with an average global intensity rate of 2.32 tons of CO2 per ton of crude steel (tCO2/t crude steel) according to 2021 worldsteel’s data. There are alternative production routes with lower emission intensity rates, such as electric arc furnaces based on direct reduced iron (DRI) or scrap, with global average intensity rates of 1.65 tCO2/t crude steel and 0.67 tCO2/t crude steel, respectively (2021 worldsteel´s data accounting for scopes 1, 2 and 3 based on its sectoral approach methodology).

However, the selection of the production route depends on the availability and the cost-efficiency of resources, given that the steel industry operates in a highly competitive scenario. As developing economies advance and infrastructure enters a replacement phase, the availability of obsolete scrap will increase, which in turn could support a shift from steelmaking technologies based on iron ore to those relying more heavily on steel scrap. Over time, this shift could have a significant impact on iron ore and steel scrap consumption trends globally.

On the energy side, while renewables availability has improved in the last years, major projects must be executed to replace traditional energy sources and market conditions must be set by local governments incentivizing this transition.

Steel, with its versatility, strength, durability, and infinite recyclability, stands as the foundation of a sustainable transition, enabling a circular economy, reducing environmental impact, and meeting evolving global needs.












Access and availability of renewable energy sources such as wind, solar, and hydropower are also an essential element in the transition to a low-carbon economy. Renewable energy plays a pivotal role in the production of green hydrogen as part of a more advanced stage of decarbonization projects. This is because the electrolysis process used to produce green hydrogen relies heavily on electricity, and if this electricity comes from non-renewable sources, the process may not be carbon-neutral as expected.

As the world shifts towards a low-carbon economy, the steel industry plays a critical role. It has the ability to produce steel to be used in renewable energy infrastructure, such as wind turbines and solar panels. Additionally, steel solutions like carbon capture and storage technology contribute to decarbonization efforts. Moreover, lightweight high-strength steel is vital for helping other industries, like automotive, decarbonize their activities.

TERNIUM'S PATH TO REDUCE CARBON EMISSIONS:
A CLOSER LOOK AT THE COMPANY'S DECARBONIZATION ROADMAP

In 2021, Ternium announced a medium-term target of a 20% reduction in its CO2 emission intensity rate at its steelmaking sites by 2030, considering scopes 1 and 2 emissions, compared to 2018 levels.

To achieve this medium-term goal, Ternium developed a comprehensive roadmap that takes into account its production settings, mature technologies, available
resources, local regulations, and the national commitments made by countries under the Paris Agreement. The resulting strategy comprises six key axes: Increasing the use of DRI-EAF in the production mix; expanding carbon dioxide capture and usage capacity; increasing the use of renewable sources in the energy mix, further advancing Ternium’s energy efficiency program, intensifying the use of scrap in the metallic mix, and partially substituting metallurgical coal with biomass.

Given the relevance of climate change for Ternium’s overall business, the company's board of directors conducts quarterly reviews of the development and implementation of its decarbonization strategy. To ensure an effective progress tracking, the Board nominated its Vice-Chairman to oversee, on a quarterly basis, Ternium's climate change strategy. Additionally, Ternium has established a decarbonization committee,

CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
with the CEO's participation, commissioned with monitoring project execution, market trends, regulatory changes, and proposing new courses of action to achieve the company's decarbonization objectives.

Ternium has recently disclosed its plans to execute significant projects over the next few years in line with its decarbonization roadmap. The most relevant project is the construction of new upstream production capacity at our Pesquería facility based on DRI-EAF technology. This project aims to increase the participation of this route from 29% to 39% by the year 2026. The DRI module will be readied, as the rest of our DRI modules in Mexico, to switch from natural gas to green hydrogen use.

The company also announced a wind farm project in Argentina, which involves an investment of
approximately $160 million. The wind farm will replace 65% of the electricity purchased from third parties in Argentina, resulting in a reduction of 92,500 tons of CO2 emissions per year.

In the long term, achieving carbon neutrality will depend on multiple technological breakthroughs, and Ternium, along with its affiliate companies, is actively working on them. Tenova, a supplier of equipment and technology for the steel industry, is assisting in the development of carbon capture equipment and hydrogen-based burners. Tecpetrol's Energy Transition Business Unit is collaborating in the development of renewable energy projects, carbon capture and storage facilities and green hydrogen infrastructure. Additionally, Tecpetrol has launched a venture capital initiative to foster the growth of start-ups with the aim at accelerating decarbonization opportunities.

Based on the potential that Latin America holds in terms of nature-based solutions, Ternium is currently conducting pre-feasibility studies for its participation in projects that involve biomass production and utilization, as well as for the protection and reforestation efforts in affected areas.

One of the potential projects focuses on expanding mangrove canopies, as these ecosystems play a crucial role in mitigating global warming by absorbing significant amounts of CO2. This innovative approach aims to compensate for residual emissions in the long term, addressing climate change while benefiting both human well-being and biodiversity.

Collaborative Efforts Required to Tackle
Climate Change

Reducing carbon emissions is a critical long-term goal that requires significant changes at a global level.

Encouraging the widespread adoption of green energy and improving energy infrastructure are necessary to ensure a reliable supply for both industry and residential areas. Disruptive low-carbon technologies and carbon capture and storage solutions must be developed and made commercially available for the industry. Governments have a role to play in promoting emission intensity reduction and incentivizing national industries through initiatives like the Inflation Reduction Act (IRA) in the US. It is crucial to ensure a level-playing field for all actors and prevent carbon leakage between regions. The financial sector should support investment projects that contribute to mitigate climate change and create favorable market conditions for these initiatives to prosper.

Aware of the sizable challenges ahead, Ternium has already set strategic alliances along its supply chain while promoting joint efforts with several other stakeholders in order to achieve its decarbonization goals.

Ternium recognizes that minimizing its environmental footprint presents a chance to foster innovation and new technologies, while collaborating with partners across the value chain towards a sustainable future.
In this regard, in 2021 the company signed a memorandum of understanding (MoU) with Vale, Ternium’s main iron ore supplier, to jointly study the
use of iron ore briquettes at its blast furnaces, along with the economic feasibility of investing in an iron ore briquetting plant with Vale's technology at Ternium’s Brazil facility. Briquette technology enables the utilization of fines with lower iron content, thereby increasing efficiency in the utilization of natural resources and providing flexibility in Ternium’s iron ore supply scheme.

In this same line, in 2022, the company conducted successful pilot and industrial tests for the use of various types of charcoal derived from biomass and forestry as a substitute for mineral coal in the coking facilities at its steelmaking sites in Brazil and Argentina. Efforts are now underway to identify charcoals with sustainable certification.





SYNERGIC PARTNERSHIPS
The decarbonization of the value chain in the steel industry is of vital importance in order to achieve net-zero emissions. Collaborative efforts are critical to achieving a sustainable future.

CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
As part of its sustainable procurement practices, the company is working on gathering information about the emission intensity of Ternium’s raw material and slabs purchases. This initiative is expected to have a significant impact in the registration of CO2 emissions in our suppliers’ base while helping us improve our assessment of scope 3 emissions. As a result of the 2022 campaign and after reviewing the information gathered, we incorporated to Ternium' scope 3 inventory specific emissions data from suppliers representing 67% of the purchases of raw materials and steel.

Ternium also collaborates with small and medium-sized local suppliers, assisting them in improving their own assessment of their product's footprint while identifying opportunities to reduce emissions and achieve energy efficiency in their internal processes (For more information please refer to “Strengthening Our Value Chain” Chapter).

Institutional Support for Decarbonization

Ternium is an active member of the World Steel Association (worldsteel) and a signatory of worldsteel’s Sustainable Charter, reaffirming its commitment to worldsteel’s sustainability principles. Within worldsteel, Ternium participates in several initiatives to measure and reduce CO2 emissions (Climate Action program and Step Up program) and reports on worldsteel sustainability indicators. In recognition of the company’s support and contributions, worldsteel has distinguished Ternium as Sustainability Champion for five years in a row.

Over the past few years, the company has been actively involved in various global initiatives focused on identifying optimal pathways for decarbonizing the industry. One notable example is the Technical Working Group (TWG) of The Net-Zero Steel Pathway Methodology Project, in which the company participated during 2021. This private sector initiative aims at establishing a feasible decarbonization roadmap for the steel industry, considering available technologies and their proposed decarbonization alternatives. The current steel sector decarbonization approach (SDA) under the SBTi (Science Based Target Initiative) treats the sector as homogenous, assessing a company’s carbon intensity target against a single carbon budget for steel,
As part of Ternium's 2022 emissions assessment campaign, data from suppliers representing 67% of slab

without distinguishing between steel produced from iron ore (primary steel) or steel produced from scrap (secondary steel). The TWG report highlights the particularities of the industry and suggests common principles for a consistent assessment of the companies’ CO2 emission reduction targets, along with the contribution needed from the sector.

The company also promotes the definition of regulatory frameworks in the steel markets where it operates to ensure a level playing field between regions during the transition to carbon-free technologies. With that objective, Ternium maintains an active participation in national steel and industrial associations like Alacero in Latin America.

aiming at meeting its 2030 target. The company is considering multiple scenarios in its strategy, including the International Energy Agency's Current Policy and Sustainable Development scenarios, which were published in October 2020, as well as the Nationally Determined Contributions (NDCs) of the countries where Ternium has steelmaking facilities. The company evaluates the commitments made by each country and leverages this information to develop an scenario for planning purposes. For example, Mexico has pledged to reduce emissions by accomplishing a 37.7% participation of renewable energy in the energy mix by 2030. Ternium’s Decarbonization Roadmap considers a 43% of participation of renewables at its Mexican steelmaking operations by 2030.

The company closely follows changes over time to the countries' pledges so it can adapt its roadmap to those objectives. For example, in March 2022 the Brazilian government confirmed its target to reduce by 37% its
emissions by 2025 and 50% by 2030, compared to 2005 levels. The government has called upon the steel sector to develop a GHG mitigation curve as a starting point for discussions on the potential design of ETS (Emissions Trading System) regulations. Ternium is actively collaborating with other industry members to craft this plan, considering the available technologies and necessary changes within the steel industry's supply chain. The objective is to establish a framework that supports both environmental sustainability and the competitiveness of the sector.

Along with this, Ternium has also taken into consideration various scenarios designed by third party experts, particularly with regard to climate-related physical risks. In 2022, the company completed a vulnerability analysis of 18 operational sites in Mexico, Argentina, Brazil, Guatemala, Colombia and the US, encompassing 100% of the company's crude steel production.

46. TERNIUM_SUSTAINABILITY REPORT 2022
CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
Results of a third-party assessment conducted in 2021 and 2022 show that none of Ternium's main sites present
a 'very high' or 'high' physical risk index.






The analysis considered the exposure to five natural hazards: pluvial floods, tropical cyclones, landslides, wildfires and droughts, and was carried out by an independent consultant firm through models based on different scenarios, which included the Representatives Concentration Pathway (RCP) 4.5 Celsius degrees scenario (intermediate), and the RCP 8.5 Celsius degrees scenario (extreme) from the Intergovernmental Panel on Climate Change (IPCC). These analysis covered two timeframes: 2020 to 2039 and 2040 to 2059. The analysis concluded that Ternium's facilities are not vulnerable to acute risks, considering the level of exposure and mitigation measures implemented by the company within the defined scenarios and timeframe.


TERNIUM'S STRATEGIES FOR IDENTIFYING AND ASSESSING CLIMATE-RELATED RISKS

Under Ternium’s Risk Management Policy, climate- related risks are identified and evaluated at a local level with the participation of its environmental, industrial and planning departments. All detected risks are classified according to a risk matrix that considers economic impacts and the probability of occurrence. All risks are reviewed at least three times a year and the ones classified as significant, highly significant or critical are discussed in the Critical Risk Committee, which is chaired by the CEO.
During these meetings, each business unit presents their mitigation plans, which are then approved by the committee.

Ternium classifies climate-change risks into two categories: transitional risks and physical risks. The company regularly evaluates the impact of changes in GHG emission policies and the increasing climate regulatory requirements. As part of this process, Ternium assesses government initiatives aimed at reducing GHG emissions, such as the introduction of carbon taxes, carbon-pricing systems, the adoption of "cap-and-trade" regulations or other measures to control GHG emissions. While the current policies in force in the countries where Ternium has industrial facilities do not have a significant economic impact in the company, future regulatory changes could eventually increase Ternium’s operating costs.

For instance, the 2017 tax reform in Argentina introduced a tax on certain fossil fuels. Natural gas, considered the transitional fossil fuel to decarbonization, was excluded and metallurgical coal and petrochemical coke were exempted as long as they are used as part of an industrial process other than for energy generation. Similarly, Mexico approved carbon taxing rules applicable to fossil fuels in 2013 and set a zero tax on natural gas. Later, in 2019, the government presented a pilot program for an Emissions Trading System (ETS) that would set a cap on emissions and allow the trade of emission certificates. In addition, the Brazilian Congress has been discussing initiatives to introduce a carbon pricing mechanism on industrial processes and power generation facilities, which could result in incremental costs for Ternium’s steel production in Brazil.

The company also monitors the economic impact of natural disaster scenarios, such as hurricanes, cyclones, droughts, floods and fires or extreme weather conditions (physical risks). For example, in 2020 and 2021, iron ore supplied to the company’s operations in Argentina from Brazil’s 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 levels. To avoid operational disruptions, the company worked on improving its management of iron ore inventories, including new river transportation strategies and the development of new supply agreements to secure alternative sources.

Sometimes, in the face of unexpected and isolated events, production suffers interruptions. For example, during the first quarter of 2021, extreme weather conditions in the southern United States and northern Mexico disrupted the provision of natural gas and energy to the company’s operations in Mexico, negatively affecting steel production levels for a short period of time. As extreme weather events become more frequent, the company will continue strengthening the analysis of climate-related risks, their potential implications and the probability of their occurrence.

PIONEERING CARBON CAPTURE
FOR MORE THAN 20 YEARS

Ternium's Guerrero unit in Mexico incorporated direct reduced iron (DRI) technology back in 1998, which was exceptional at the time. Its Direct Reduction Plant revolutionized the industry with its cost-efficiency and environmentally conscious design.

Equipped with CO2 removal units that use amines technology, the facility captures and commercializes the CO2 generated during the reduction process as a co-product. This process helps to avoid emissions in other industries.

Since then, DRI technology was also successfully deployed in Ternium's facility in Puebla, Mexico.

Furthermore, the recently installed hot-rolling mill in Pesquería, Mexico, is equipped with advanced technology that enables the production of high-value-added steels that are suited for the manufacturing of electric vehicles, supporting the automotive industry’s efforts to increase EVs participation in automotive sales. In 2022, Ternium initiated efforts to develop key Electrical Vehicle components to foster the application of its high strength steels in this very dynamic segment.

For the construction sector, Ternium has designed a new family of sustainable coil-coated steels and insulating panels, combining eco-friendly components and energy-saving solutions.

In 2022, Ternium sold approximately $ 86 million worth of products that were linked to renewable energy projects, electric vehicles, or transportation solutions designed to achieve weight reduction or improved capacity. The company expects this figure to continue growing in the upcoming years.


TERNIUM’S CARBON FOOTPRINT: A STEP TOWARDS TRANSPARENCY AND ACCOUNTABILITY

In 2022, Ternium’s CO2 emission intensity rate (scopes 1 and 2), stood at 1.7 tons of CO2 per ton of crude steel production, relatively in line with previous years and with the average of the global steel industry according to worldsteel's figures.

In 2021, the company took additional steps towards decarbonization by increasing the carbon capture and usage capacity at its Guerrero and Puebla facilities in Mexico. In 2022, the company captured 261 thousand tons of CO2 from the process, which then were sold to third parties. This prevented emissions in industries such as beverage and chemical, and is equivalent to the annual CO2 output of 58 thousand gasoline-powered passenger vehicles as defined by the United States Environmental Protection Agency (EPA). The figure represents a 40% increase in carbon capture and usage compared to 2017.

The second phase of expansion of the CO2 capture and usage capacity at these facilities is under technical analysis. Its execution will ultimately depend on the expansion of demand for CO2 in the market. Given the positive experience in Mexico, studies for CO2 capture and usage at the company's facility in Brazil are currently under development.

The company is actively exploring projects aimed
at replacing coal in the production route of Argentina and Brazil. One of those projects consists in increasing the use of pulverized coal to improve the reduction process while obtaining economic advantages. To this end, the company installed a PCI Injection System in the blast furnace in Brazil in 2022.

We anticipate that our CO2 emission intensity rate will show more significant decreases after 2025, as our decarbonization projects are finalized and reach their full operational stage.

In addition to analyzing specific projects aimed at reducing CO2 emissions, the company has been working on improving the management systems for monitoring, reporting, and verifying greenhouse gas (GHG) emissions.

Ternium applies worldsteel's methodology and the GHG Protocol corporate inventory with an operational control approach to quantify GHG emissions. We have implemented monthly monitoring of CO2 emissions from the steel mill and we are actively working towards further enhancement by implementing the GHG Protocol at the production process line level. The improvements made in tracking and registration of CO2
have allowed for the successful verification of indicators, for the second consecutive year, by an external consultant.

Our next steps include conducting a materiality analysis of all scope 3 categories to quantify and include the relevant ones in our inventory. Currently, the company's scope 3 corporate inventory under GHG Protocol methodology includes purchases of goods and services (raw materials and steel), upstream and downstream transportation, and employee travel (only for Brazil).

economy and minimizing CO2 emissions by efficiently
managing its energy supply.

Depending on the technology being used, Ternium power plants in Brazil and Argentina reutilize recovered residual gases from iron and steel production processes like Blast Furnace gas (BFg), Basic Oxygen Furnace gas (BOFg) and Coke Oven Gas (COg) and residual heat from coke making.

The power plant at our Rio de Janeiro facility supplies energy for the steelmaking process and sells 46% of the electricity generated to the Brazilian national grid. In addition, the company is reducing its natural gas consumption in Brazil by using biomethane obtained from solid urban waste. The fossil natural gas substitution rate with biomethane was approximately 6% in 2022, turning it into a flexible and renewable energy source.

In Mexico, Ternium relies on Techgen, a combined cycle power station owned in partnership with Tenaris and Tecpetrol, as its primary electricity supplier. Ternium contracts 78% of Techgen’s capacity of approximately 900 megawatts and sells unused electricity to the Mexican market. The utilization of electricity from Techgen represents a reduction in Ternium’s scope 2 emissions of approximately 7% compared to the utilization of electricity from the national grid. In addition in 2022 Ternium procured clean energy certificates equivalent to 14% of its total electricity consumption through Techgen.

In Argentina, the company uses process gases to produce most of the electricity required by the operation. This represents 56% of the total consumption. Self generated electricity is expected to increase once the wind farm in Argentina is fully operational in the second half of 2024 and replaces 65% of the electricity purchased from third parties.

Looking ahead, Ternium aims to achieve a target of 40% renewable energy in its energy mix by 2030.

Ternium's Commitment to Continuous Improvement

Energy efficiency plays a vital role in the decarbonization efforts as it helps to reduce energy consumption and minimize greenhouse gas emissions.
It also has economic benefits as it reduces energy costs and enhances overall productivity.

In 2014, the company launched a comprehensive energy efficiency program to identify and capitalize on opportunities for energy savings. Since that day, the energy efficiency program has expanded and it is yearly reviewed in light of the latest technology developments and the best market practices. In 2022, the company incorporated a new PCI injection system and a blast furnace automated expert operation system based on artificial intelligence in Brazil to improve the blast furnace operational performance.

In Argentina, Ternium initiated a technological update of motors in the descaler system of the hot strip mill at the San Nicolas facility by installing high-efficiency equipment. We are also in the process of replacing the steel ladle dryer-heaters in order to reduce the consumption of natural gas on the line, also improving safety conditions.

Our corporate building at the Universidad facility in Mexico has already achieved self-supply of 90% of its electricity needs through solar energy and the company has plans to install solar capacity in its service center in Apodaca in the last quarter of 2023.

Ternium’s top energy-consuming operations are in the process of certifying their energy management system under ISO 50001. At this stage, the Rio de Janeiro unit in Brazil, the steel shop and the hot rolling mill at the San Nicolás unit in Argentina, the Guerrero unit and the Pesquería unit in Mexico, have all completed the ISO 50001 certifications. Next steps include Puebla and Apodaca facilities in Mexico and the downstream facilities in Mexico as part of a more comprehensive plan to be deployed over the next five years.

ENVIRONMENTAL RESPONSIBILITY

Ternium considers environmental protection to be a core value, and as such, has implemented a corporate environmental and energy policy that establishes its principles and objectives, including the conservation of natural resources, the reduction of pollution and the proper waste management. The company strives to achieve the highest standards of environmental performance to ensure sustainable development and encourages its supply chain to follow the same principles.

The company’s commitment to environmental sustainability is supported by an environmental and energy management system that encompasses every production unit. The company conducts regular audits and certifications to update its environmental and energy management processes and to identify opportunities for improvement. Currently, Ternium’s


RESPONSIBLE OPERATIONS
IN WATER-STRESSED AREAS

Ternium prioritizes responsible water management in its operations, employing a site-specific strategy that considers local conditions.

We utilize advanced technologies to optimize water management across the entire cycle, from intake to discharge and prioritize the use of non-potable water for industrial purposes. This minimizes our ecological footprint and supports a sustainable water usage.

steel production facilities are certified under ISO 14001, the environmental management standard.

To improve environmental performance, Ternium established a 10-year plan of environmental projects in 2020, which is updated annually. The current plan has a total budget of $470 million for the period 2023-2030.


WATER EFFICIENCY STRATEGIES

Ternium places a strong emphasis on responsible water management in its operations. The company has implemented a site-specific water management strategy that takes into account the unique characteristics of each location where it operates. Through continuous incorporation of cutting-edge technologies, Ternium aims to improve water management practices across the entire water cycle, from intake to discharge, in order to reduce its environmental impact and contribute to sustainable water usage.

Water availability is different in each location where Ternium operates. Based on the water risk atlas of the World Resource Institute (WRI), about 11% of Ternium’s total water withdrawal in the steel segment is located in areas of high water stress, mainly in Mexico. If we consider the water intake for cooling purposes in power plants, the exposure would come down to 2%.

Ternium carefully considers the proper use of water as a key resource when designing new facilities. The industrial center in Palmar de Varela, Colombia, inaugurated in February 2021, serves as a prime example of this commitment. The facility was designed with a 100% closed circuit system, meaning that the company only sources water from a third-party for replenishing purposes due to evaporation.

Over the years, Ternium has developed different strategies to minimize water usage at its Mexican steelmaking facilities, achieving a water use intensity rate of just 3.3 cubic meters per ton of crude steel produced in 2022. This figure is significantly lower than the average reported by a worldsteel study in 2011, which established an intake intensity of 28.6 m3 per ton of crude steel for a Blast Furnace based facility and 28.1 m3 per ton of crude steel in a facility with Electric Arc Furnace technology.

The company has also consistently increased the use of third-party water, mostly sewage water from external wastewater treatment plants or directly
sourced from the city's sewage system. As a result, the participation of third-party water at our Mexican facilities’ water intake reached 49% in 2022 from 44% in 2018.

At present, the utilization rate of sewage water in the Pesquería facility is 94%. The upcoming capacity expansion project will also utilize sewage water instead of groundwater, resulting in an increase in the use of wastewater at Mexican facilities. This project will require an expansion of the current water treatment plant's capacity.


Water plays a significant role in Ternium’s production system, both in steam generation and in cooling machinery. In this regard, the company's efficient water management system ensures that the majority of the water used (94% in 2022) is cleaned, cooled, and safely returned to its source.

parameters. Over time, Ternium has integrated advanced technologies and monitoring systems to enhance the quality of water discharges while reducing their environmental impact.

In 2022, the company invested in improving the final treatment of the main plant effluents at its San Nicolas facility in Argentina through the construction of two sedimentation pools. The pools have a treatment capacity of 32,000 m3/h and include entry chambers to standardize the flow velocities of the incoming effluents, dredges for sediment extraction, and an oil skimmer system. An impermeable yard was also constructed to dehydrate the extracted sediments using geobags.
The company had also completed the construction of a treatment plant for the rain water from the pet coke yard. This plant, through a physicochemical process, triggers the sedimentation of solids that are later reused in the sintering process or sold to the cement industry, transforming this material into a useful input for both industries.

In Brazil, Ternium has optimized water management tools by implementing online dashboards to track water reuse. This allows for real-time decision-making, thus avoiding delays in the performance analysis. In this facility, the company has also incorporated a Water Resources Committee to review water usage at each stage of the production process.

AIR QUALITY

Ternium is committed to minimize its impact in air quality. In 2021, the company initiated a comprehensive project at its Guerrero unit in Mexico, which includes the construction of a dome in the iron ore yard, silos for the collection and storage of DRI, a wet dust collector suction system, and cladding of the steel mill façade. These measures will significantly reduce dust emissions from materials handling and transportation. The project is scheduled to be completed by 2025.

The company is also advancing a project at its steel shop in the San Nicolás unit in Argentina to further enhance its environmental performance by increasing the dust collection capacity with the revamping of the entire collection system, vertical ducts and flow control systems. In addition, Ternium expects to incorporate in this facility cameras and monitoring systems to strengthen its environmental management and operational control.

The company is utilizing cutting-edge technology for real-time air quality monitoring. LiDAR (Light Detection and Ranging) technology is currently undergoing testing at the San Nicolás unit in Argentina and the Rio de Janeiro unit in Brazil. This technology uses laser beams to assess site particulate matter emissions and establish virtual monitoring stations. This enables the company to gather real-time information about air quality impact and make informed decisions about environmental management.


BUILDING A CIRCULAR ECONOMY: TERNIUM'S FOCUS ON MATERIAL EFFICIENCY AND RECYCLING

Steel is a material that holds immense potential for a sustainable future, thanks to its endless recyclability without any loss in quality or properties. All the steel scrap generated in Ternium’s facilities is recycled. The company also purchases steel scrap from either scrap-processing companies or scrap collecting firms.

CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
In 2022, Ternium recycled 2.8 million tons of steel scrap to produce new steel, retaining all its properties.

The company is seriously committed to minimizing waste and maximizing material efficiency in its operations. We continuously develop and implement strategies to reduce the production of waste and maximize the use of co-products. In 2022, Ternium achieved a material efficiency rate of 99% in its steel operations, with 5.1 million tons of co-products being reused in the production process or sold to other industries.

Co-products mainly include blast furnace and steel shop slag, iron oxide and chemical substances. The use of Ternium’s co-products by other industries reduces their consumption of raw materials and energy, with a positive effect on carbon dioxide emissions and waste generation in the value chain as a whole.

In facilities with blast furnaces, the granulated slag is sold to the cement industry as a substitute for clinker. In 2022 the company sold 1.9 million tons of slag avoiding CO2 emissions of 1.1 million tons. Additionally, the slag generated in the steel shop is also used to consolidate roads and therefore avoiding the use of materials in other industries. As an example, during 2022, the company delivered over 360 thousand tons of recycled aggregate slag to pave the Santa Cruz industrial district main access roads in Rio de Janeiro, Brazil.

In Mexico, the dust generated by the electric-arc furnaces at its Guerrero and Puebla units, is transformed into Mix Rock® and other mixes, innovative co-product developed and registered by Ternium. These mixes and Mix Rock® enables the re-use of EAF dust and slag as a substitute for iron ore in the clinker production process in the cement industry. In 2022, Ternium sold 125 thousand tons of Mix Rock® from Guerrero and mixes from the Puebla and Churubusco units.

In addition, Ternium has sinter and briquetting
facilities that allow the recycling of different materials
captured by its air and water treatment equipment,
including iron ore fines, coal, lime and dolomite.

In the Blast Furnace route, significant amounts of processes gases are generated during the processing of metallurgical coal. In Argentina, Ternium utilizes these gases to produce chemical products such as tar and benzol, which are sold to third-parties.
Ternium meets customer demands with environmental product declarations (EPDs) for eight product families, offering transparency on steel products' environmental impact. EPDs include carbon footprint and materials used across the production processes, enabling informed decision-making.








Local governments play a vital role in promoting a circular economy by incentivizing the commercialization of co-products and scrap metal generated during the steel production process. One approach is for governments to start recognizing scrap as a raw material, rather than just considering it as waste. This would change the rules concerning waste disposal, thus fostering a more sustainable future and unlock the full potential of the circular economy.


LIFE CYCLE AND ENVIRONMENTAL PRODUCT DECLARATIONS

Ternium assesses the life cycle of its steel products and participates in worldsteel’s life cycle assessment (LCA) initiatives to help document and improve the steel product’s environmental footprint.

Conserving Mangroves in Brazil: Ternium's Protection of 160 hectares (395 acres) in Sepetiba Bay, Rio de Janeiro
A steel LCA involves, among other indicators, a thorough inventory of the energy and materials utilized across the industry value chain, according to ISO 14040 and 14044 standards, to determine the greenhouse gas emissions of the products. Ternium’s LCA inventory reporting encompassed 92% of our crude steel production.

In response to customer demands for greater transparency on the environmental impact of steel products, Ternium has developed environmental product declarations (EPDs) for eight product families. These EPDs provide detailed information on the environmental impact of each product, including its carbon footprint and other relevant data. Customers can access this information on Ternium’s website. EPDs also help to achieve credits in certification schemes such as LEED (Leadership in Energy and Environmental Design). Our facility in Pesquería was certified under LEED in 2017.

The results of this research were presented at the XIII Congress of the Latin American Society of Specialists in Aquatic Mammals (SOLAMAC). The scientific research sponsored by Ternium is currently in the submission stage for publication in scientific journals.

Iberá wetlands

Ternium sponsors the projects of the Rewilding Argentina Foundation at the Iberá wetlands, a protected area located at the northeast of Argentina. These projects have been incorporated into National Geographic Society’s Last Wild Places initiative. They seek to reintroduce in this area species that are considered extinct or endangered, such as the giant otter and the yaguareté, a kind of jaguar.

In 2022, following the devastating fires that occurred in this area during an extreme drought spell, Ternium, Tenaris and other members of the Techint Group donated materials to help with efforts to recover the local ecosystem. The donations included 53 tons of Ternium’s steel products (including sheets, profiles, and structural tubes) and machinery such as tractors to replace the perimeter fencing destroyed in the blaze, vital for keeping livestock separate from wildlife.

Expanding green areas in Ternium's facilities

In line with its commitment to environmental sustainability, Ternium has been actively engaged in reforestation projects over the last five years.

The company's efforts have focused on mining sites from Las Encinas in the Mexican states of Michoacán and Jalisco to compensate for the impact of the extractive activity in the area. In 2022, we planted approximately 136 thousand individuals of 29 native species as part of this reforestation program.

CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
SAFETY AS OUR NUMBER ONE CONCERN

The safety and well-being of Ternium’s employees are of paramount importance and serve as key drivers for the organization's long-term sustainability. Ternium endeavors to establish and maintain a safety culture that is dedicated to preserving the well-being of its employees. With this principle in mind, safety conditions are the primary consideration for any individual when initiating and carrying out their activities. Moreover, managers hold the responsibility for ensuring the occupational health and safety of all individuals working within their assigned areas.


FOSTERING A CULTURE OF PROCESS SAFETY

Process safety holds vital importance in the steel industry, as it plays a crucial role in preventing major incidents and ensuring the well-being of employees, the environment, the company's assets. The processes involved in steel production poses inherent risks that require systematic identification, assessment, and effective management.

Process Safety management is a core process at Ternium and involves assessing, understanding and managing risks associated with operations with the aim of reducing and ultimately eliminating injuries and incidents due to hazardous substances, materials and processes. We build our process safety management upon proactive initiatives, encompassing
comprehensive risk assessments, equipment design
and maintenance, well-established safety management
systems and thorough employee training. Compliance with industry regulations and standards serves as a starting point as we strive for continuous improvement and maintain an unwavering commitment to protecting people and the environment.

Ternium’s process safety management model, known as ASP (for its Spanish acronym), is strongly aligned with the criteria of adopting leading global best practices in this discipline. It comprises 14 management elements categorized under three main pillars: technology, facilities and people. The objective is to achieve operational excellence through high standards of operational discipline and the continuous improvement of industrial processes.
"There should be no doubts among any of the people who work at Ternium that safety comes first."

MÁXIMO VEDOYA


















In 2022, Ternium continued to advance its process safety cultural growth and consolidated preventive activities based on management criteria. We made progress in process risk analysis, which resulted in the development of new critical operating procedures. We conducted preventive measures such as fire drills and audits and we implemented risk insurers' recommendations thoroughly.

Furthermore, with a long-term vision in mind, we developed a five-year strategic plan, integrating shared objectives and initiatives within the company's maintenance areas. Among these initiatives are the creation of specific committees and the establishment of a common agenda in line with outlines set by widely recognized international organizations. Additionally, we improved risk analysis procedures incorporating the Bow Tie methodology into the process safety system along with tools to enhance the investigation of process safety-related events. The strategic plan also

OCCUPATIONAL HEALTH AND SAFETY INITIATIVES

Ternium articulated strategies to align the organization's culture with its Safety Vision, aiming at preventing accidents, ensure the safe management of production process, and foster engagement among employees, customers, and suppliers through effective communication. These strategies seek to promote the adoption of safe behaviors as a fundamental element of the company's culture, under the phrase "Safety First".

Risk assessment and the management of Occupational Health and Safety (OH&S) are seamlessly integrated into all business processes,
reflecting Ternium’s OH&S policy. The leaders assume responsibility and accountability for OH&S performance within a broader framework of goals, with senior managers leading the implementation of strategies to fulfil the company’s Safety Vision.

Ternium relies on an OH&S management system that complies with the company's policy, as well as local and national laws and regulations. Periodic audits of processes and procedures are conducted to identify new opportunities for enhancing the safety management system and ensuring compliance with the company’s policy.

The company’s health and safety management system is certified under the ISO 45001 standard. Currently, 91% of employees and contractors working at company infrastructure operate in ISO 45001 certified facilities, including both upstream and downstream.

External Audit: Ternium personnel receiving an external audit in the company's grinding and pelletizing control room at the Alzada mining facility in Mexico.
To maintain a standardized approach to recording environmental, health, and safety (EHS) information across all locations, including data related to preventive and corrective tasks, Ternium utilizes a platform called SIASSO (Sistema Integrado de Ambiente, Seguridad y Salud Ocupacional for its acronym in Spanish). This platform collects and processes user-reported information, which is then transformed into various EHS indicators to monitor performance, identify necessary corrective actions, and make informed decisions.

Unifying Culture and Safety
A few years ago, the company introduced its long-term Safety Vision, which encompasses strategies to establish a safety culture centered around leaders and people's behavior and which requires active engagement at all levels of the company.
One of the key components of the program is the Safety and Environment Hour initiative, during which middle and senior leaders dedicate an hour, three times a week, to tour operational areas across the production facilities. This initiative serves multiple purposes, including identifying safe behaviors that can be replicated across different facilities and addressing unsafe acts or situations through open dialogue with employees. This visit to the facility has specific objectives for each leader, which may include observing and evaluating factors such as people's behavior, safety conditions, presence of precursors in the area, operational discipline, and critical activities.

In 2022, an initiative was launched to evaluate the effectiveness of the Safety Hour as a preventive tool.

The process involved conducting surveys, workshops, and establishing multidisciplinary working teams that

represented all the regions where we operate. This approach allowed us to redesign the tool effectively. The proposed improvements aimed to enhance the quality of plant visits and foster better interaction between leaders and their work teams.

In addition to the Safety Hour program, the company conducts verification audits according to the specific needs of each area to ensure compliance with relevant OH&S policies, procedures, and practices. Last year, over 15 thousand health and safety audits were conducted outside the Safe Hour formal scheme.

Leadership Engagement: Driving Change through
Active Involvement

Ternium is pursuing a cultural transformation regarding people's safety, and one of the key
focuses is the development of leaders who embody that vision and extend best practices. One of the tools to achieve standardization and dissemination of best practices is the development of a comprehensive guidebook for managers.

This manual serves as a valuable resource, outlining expected behaviors and effective decision-making processes under various scenarios. It was created based on the insights and experiences shared by a diverse group of over 300 directors and managers from across the organization through virtual and in-person sessions.

During these gatherings, participants discussed various topics relevant to leadership, including the 7 best practices, common mental pitfalls, the Bradley curve, along with significant milestones in the field. Additionally, a dedicated website was designed in order to offer continuous support and resources for the implementation process. These best practices have also been extended to supervisors, with further plans to include hourly employees and contractors.


STAYING AHEAD: IMPLEMENTING PREVENTIVE MEASURES FOR SAFETY

Ten life-saving rules

Ternium has established the Ten Life-Saving Rules, a comprehensive set of actions designed to safeguard the lives of employees and contractors. These rules incorporate worldsteel's guidance and are the result of extensive research, including focus groups and studies conducted to identify the primary causes of high-severity accidents and fatalities at the company’s facilities. They are supported by established practices and routines that must be strictly adhered to by all employees.

The Ten Life-Saving Rules have been widely communicated across all of Ternium’s operations.
It aims at raising awareness among employees, customers, and suppliers, and they are subject to regular audits to ensure strict adherence. Given its importance in 2022, over 30,000 audits were conducted, with specific focus on the Ten Life-Saving Rules.

Task Rejection Tool

This tool strengthens people’s determination not to start or if started, to suspend a task when they consider that an uncontrolled risk is present. Task Rejection helps prevent injuries resulting from a lack of effective control of previously identified safety risks.

The company encourages the use of this tool and has started recognizing workers when their personal analysis of Occupational Health and Safety conditions prevents the occurrence of a high-risk event. In 2022, we recorded approximately 18,000 reports, 12% of which involved potential high risk.

Enhancing Safety Through Pre-Shift Assessments:
A Proactive Approach to Minimize Accidents

The company has identified behavioral factors, such as distraction, as contributing to certain accidents. In order to minimize these behaviors, an initiative has been implemented to assess the condition of workers prior to their shifts. Initially, the focus is placed on workers who perform high-risk activities, with the goal of determining their level of concentration on these tasks.

The chosen approach is a Readiness Test, a proactive and educational evaluation that helps identify behavioral risk factors among workers. This test is conducted daily to hourly employees, utilizing normalized responses and artificial intelligence to asses employees general state. Its purpose is to ensure that workers are mentally prepared and focused, effectively preventing potential incidents.

The application tests workers at the beginning of their shifts and measures parameters directly related to accidents, including impulse control, reaction time, attention, and concentration over time.

These parameters are monitored on a daily basis, providing valuable insights into workers' behavior and their physical and mental health conditions.

has the potential to result in a life-threatening, life-altering, or a fatal accident. At Ternium, we prioritize potential severe injuries or fatalities in our corrective and preventive actions, treating them with the same level of importance as if a severe injury or fatality had actually occurred. Through this approach, we aim at significantly reducing the likelihood of fatalities.

Based upon this evidence, the company has increased its efforts to identify signals of potential severe injuries or fatalities, referring to situations where there are no control measures, the control measures being applied are not being effective or people do not comply with them.

The company has identified non-controlled repeating precursors through interviews with employees on a procedure called Critical Control
Verification. During 2022, over 900 employees performed more than 11,500 critical control verifications, which resulted in approximately 5,200 new continuous improvement projects.

Training programs

Management is committed to the training Ternium’s employees, customers and suppliers on the appropriate use of the company’s OH&S management systems as well as raising awareness of risks involved in performing their tasks. After the COVID-19 pandemic, the company strengthened its online offer through Ternium University's platform. In 2022, over 17 thousand employees and contractors received an average of 19 hours of training on safety-related issues focused on preventive measures and Ternium’s OH&S programs.

INTEGRATING NEW TECHNOLOGIES IN TERNIUM'S SAFETY MANAGEMENT SYSTEM

The company has incorporated advanced technologies to enhance risk assessment, event analysis, and educational practices in the field of Occupational Health and Safety. Cutting-edge tools such as Video Analytics, drones for inspection routines, remote assistance from maintenance experts, simulations of high-risk events, and virtual reality have been integrated into our operations.

Automated video analytics continuously capture and monitor images of our operating activities, cross-referencing them with established specifications. If any deviation from the normal parameters is detected, visual, audible, or mechanical alerts are triggered, and information regarding the safety breach is automatically uploaded onto the SIASSO platform.

In addition, technology plays a crucial role in reviewing past events and extracting valuable lessons. High-risk events are analyzed using 3D technology, enabling the company to simulate these incidents, identify their root causes, and implement measures to minimize the likelihood of recurrence.

Furthermore, virtual reality training is employed for highly risky operations and maintenance activities, ensuring the safety of our employees. Currently, this tool is utilized in training sessions involving mobile equipment like forklifts and railway engines, as well as in sessions related to the manufacturing process.

This task used to be performed manually by an average of four times per steel casting. Currently, human involvement is limited to operating the robot and ensuring the availability of measurement supplies.

In Brazil, the company utilizes a robot operated from the blast furnace casting control room to apply refractory material in the casting channel. This
innovative solution not only extends the lifespan of the production system but also ensures the safety of our
personnel by reducing human exposure to temperatures exceeding 200°C.

Additionally, two new robot cells have been implemented at the BOF (Basic Oxygen Furnace) to eliminate operator involvement in steel sampling and measurement activities and increase consumables capacity as well as introducing new cleaning functionality. This solution significantly enhances the safety of the operational personnel and process.

Despite all the safety measures currently being implemented, 2022 was also marked by a tragic event, with the fatality of an employee while performing maintenance tasks in the coke plant at our slab facility in Brazil. This incident was the first fatal accident in Ternium’s facilities in the past four years, triggering a series of measures by the company's management. As part of the corrective actions, management established a plan to review all of the company's Hazard Identification and Risk Assessment (IPER) matrices, procedures, and Safe Operating Procedures (MOTS) to ensure they accurately reflect the level of risk associated with each task. Additionally, the company implemented a Technical Safety Hour focusing on works in electrical areas. Electrical experts along with Maintenance and Operations personnel, will be dedicated to identify activities with potential exposure to electrical hazards while defining action plans to mitigate or eliminate them.

More recently, in February and April of 2023, we recorded two fatal accidents involving contractors at our mining facilities, Las Encinas and Peña Colorada. These events have led us to reconsider our safety strategy for the companies providing services in our facilities, as well as to strengthen measures in mining activities. Furthermore, to have an even closer oversight of our EHS activities, the company decided that the Global EHS Vice President will report directly to the CEO from July 2023.

We are committed to enhancing safety and accident prevention, and we will continue to implement actions to ensure a secure working environment for everyone involved in our operations.

Responding to Accidents: Ternium’s Actions and Measures

Ternium’s management follows specific protocols when an accident or incident occurs at the company’s workplace, regardless of the severity of the damage or injuries caused by such event. Data collection and fact analysis are conducted by multidisciplinary teams, with the participation of the manager who has direct responsibilities in the area involved.

Safety is a core value in our business. Ternium has a Zero Tolerance for activities that could lead to serious or
fatal injuries along with a steadfast commitment across processes, facilities and the entire value chain.







Management uses all available resources that could contribute to the understanding of the event including the use of the Causal Factor Tree Analysis methodology.
Once the causes have been fully identified and understood, the company implements an action plan structured around a hierarchy of controls. The plan is presented to Environmental and Safety Committee, and three months later, an audit is conducted to determine the effectiveness of the proposed action plan in eliminating the cause of the situation or event that compromises safety. This methodology has been incorporated into the company’s OH&S system and continues to be improved under Ternium’s Safety Vision.


COMMUNICATION: THE KEY TO ACCIDENT PREVENTION

Over the years, Ternium has increased the visibility of safety issues through its communication platforms. The agenda includes videos, articles and events, with the Safety Day at the center of its communication strategy.
Ternium’s Safety Day, which takes places every year on July is an opportunity to strengthen our commitment to improving OH&S and reinforce risk awareness. During

the event, the company organizes meetings and panel discussions on OH&S management to review its safety performance in the preceding year and agree on new actions to continue improving OH&S at each facility.

The event is chaired by Ternium’s CEO and the top management of each business unit. In 2022, over 9,000 people participated in person or in online meetings. During the event, the production lines are stopped to signal the company's commitment towards industrial safety.

The company has also implemented the Safety Talks, an open-dialogue instance for plant supervisors and their teams to analyze OH&S issues selected every week by senior management. Under this program, during 2022, the company delivered 48 safety briefings to 3,500 employees.
Engaging suppliers’ managers and employees

Ternium actively pursues that all of its contractors’ employees embrace the company’s Safety Vision and goals. With this purpose, it has launched various initiatives, including meetings with Ternium contractors’ top managers and the participation of their employees at Ternium’s OH&S workshops. In addition, the company has implemented an OH&S improvement plan for contractors. This plan has been developed based on contractors’ best practices, identified through
a benchmark of their operations at the company’s facilities in various locations.

In 2022, Ternium audited the OH&S programs of 162 contractors in four countries, 39 of which were recognized for the improvements achieved during the year.

Applying the highest standards of Occupational Health

Ternium demonstrates its commitment to providing a healthy workplace through the implementation of a comprehensive occupational health program. The program is designed to prioritize the well-being of its workforce by incorporating advanced equipment and technology.

We regularly perform monitoring activities and risk analysis within our health management system to assess and manage the various factors that may impact employees' health. These factors include chemical, biological, physical, ergonomic, and psychological effects associated with work activities.


SAFETY AT TERNIUM’S MINING OPERATIONS: TAILING DAM REINFORCEMENT

Ternium holds equity interests in two iron ore mining companies in Mexico: a 100% interest in Las Encinas and a 50% interest in Consorcio Peña Colorada. In 2022, we recorded iron ore shipments of 3.5 million tons, with the majority allocated to Ternium’s steelmaking facilities in Mexico and a small portion shipped to third parties.

Currently, Las Encinas operates two open pit mines: the Aquila mine in the state of Michoacán and the Palomas mine in the state of Jalisco, while Consorcio Peña Colorada operates an open pit mine in the state of Colima.The mines are equipped with tailing dams, which are structures designed to store the waste materials generated from mining operations, known as tailings.

There are six tailings dams, of which three are undergoing closing procedures or are on standby, and three are still in operation. The main embankments of the operational tailings dams are constructed in a downstream layout. This means that the tailings are deposited at the top of the dam and gradually settle and solidify downward, while the water is released downstream. This design allows for more efficient drainage and filtration of the tailings, reducing the risk of landslides and dam failures. At the same time, this

Ternium encourages its employees to undergo annual medical check-ups with the goal of monitoring their health and designing programs that enhance their quality of life.















design has environmental benefits, as the water used to transport the tailings from the production facilities to their final disposal is recovered and reused afterwards.

The company continuously analyzes the integrity of the tailings dams. In late 2019 and early 2020, independent consultants conducted stability studies for the tailings dams at Las Encinas and Consorcio Peña Colorada that were undergoing closing procedures or were on standby. During 2021, we completed the recommendations regarding the reinforcements needed for Las Encinas. As for Consorcio Peña Colorada, we are working to obtain the permits required for the reinforcement project. Its completion is estimated to take approximately three years.

TRANSFORMING TALENT MANAGEMENT THROUGH TECHNOLOGY

Ternium has become a leading flat steel producer in Latin America by virtue of its main asset: a team of committed, innovative, industrious, diverse, and highly qualified individuals. We rely on the talent and determination of our people to shape our company in the years to come.

Over the past few decades, advances in technology have greatly affected every aspect of business, including how companies manage their employees. By embracing new technologies, companies have completely changed how they handle human resources tasks. This has allowed them to better manage their talented employees, make operations more efficient, and provide a more rewarding experience for their teams at work.

Over the past two years, the company has been working on improving human resources processes by implementing various initiatives aimed at making HR operations more efficient and streamlined.

The first initiative involved the integration of a chatbot across all available devices, including personal computers and mobile phones. This technology allows employees to perform a range of tasks, from making simple inquiries about company policies and employment conditions to transactions such as requesting time off. The application of this tool has brought multiple benefits, including reduced response times, continuous availability, and a broad reach to employees. As a distinctive feature compared to other developments in the market, Ternium's chatbot offers guidance for resolving more intricate inquiries and reinforces cultural content to further enhance Ternium's identity.

The availability of the chatbot on mobile phones has not only allowed access for operational staff and supervisors but also improved productivity by eliminating downtime associated with in person inquiries. From the company's perspective, the tool has facilitated limited interaction with HR analysts to exceptional situations and has integrated the company's principles and values into the daily lives of its employees. For example, it considers their self-identification preferences, which align with the company's Diversity and Work Environment Free of Harassment policy.
In recent years, the company has embraced changes in its way
of working through infrastructure upgrades that enhance team collaboration, the introduction
of technological tools to streamline administrative tasks and the establishment of policies that provide greater flexibility.








During 2022, the company also launched a tool aimed exclusively at simplifying administrative tasks for plant supervisors: the UX supervisor. This tool encompasses all functions related to work teams, including organizing shifts and replacements, managing break times and vacations, mandatory trainings (such as safety matters), and tracking completed or pending medical check-ups therefore facilitating a more holistic leadership approach. It also features personalized visualization and an alert system that, together, contribute to reducing the time supervisors spend on administrative tasks related to team management.

The company has embarked on a third initiative aimed at utilizing technology to standardize and enhance the efficiency and effectiveness of personnel's access to the facilities that we plan to develop in the upcoming years.

EMPOWERING EMPLOYEES 24/7 THROUGH AN AI-POWERED CHATBOT
With the goal of making Human Resources (HR) processes accessible and easier for everyone, the AI-powered HR Chatbot is changing how employees interact with HR inquiries and tasks. Ternium has developed a chatbot that uses artificial intelligence to provide quick and clear communication, offering personalized responses. The chatbot can currently handle 400 different requests, and there are plans
to increase its capabilities to cover 520. The chatbot was initially available to all direct employees of Ternium, and the company envisions extending its reach to contracted personnel in coming years. Furthermore, Ternium is actively exploring opportunities to utilize the chatbot for screening potential employee candidates.

At the same time, the company is focused on projects exploring the vast potential of People Analytics. By leveraging advanced data analytics techniques and technology, we aim to unlock valuable insights from Human Resources data within the organization. Our projects involve collecting and analyzing information related to employee performance, engagement, and development, among others.

Using People Analytics, we can extract meaningful patterns and trends, enabling us to make data-driven decisions and optimize human resources strategies. This approach allows us to identify key employee productivity and satisfaction drivers, pinpoint skill gaps, predict future workforce needs, and even reduce incidents and work-related accidents caused by or directly linked to people's behavior. By harnessing the power of Human Capital Intelligence, we aim to maximize the company’s human capital potential, and ultimately drive greater success and growth.

TRANSFORMING THE WORKPLACE: INTRODUCING NEW WORKING SCHEMES

For several years now, there has been a paradigm shift in labor relations worldwide, with a trend towards greater work flexibility. This trend has been exacerbated by the COVID-19 pandemic, which has forced companies to quickly adapt to new ways of working, including working from home and managing teams remotely.

The shift towards work flexibility has been driven by various factors, including technology, the presence of work teams in different geographic areas, and employees' demand for a better work-life balance. In this context, Ternium has developed a series of programs aimed at achieving greater work flexibility, fostering the interconnectivity of teams in different locations while extending best practices among the company's different plants.

Flexible Work: Technology, Global Teams, and Work-Life Balance Driving Change at Ternium's Administrative Offices in Buenos Aires, Argentina.
The company has implemented a hybrid work scheme that combines both in-person and remote work.
Employees are required to work at the office for a minimum of three days each week. Additionally, the company offers a program where employees can leave early for half a day, a two-week remote work program at a location of their choice, and a flexible program for recent parents and caregivers. When needed, extended leaves are also provided.

Furthermore, the company has made improvements to its facilities. This includes creating open collaborative spaces, introducing advanced audiovisual tools, and removing physical barriers that may disrupt team collaboration and workflow. The key concept of this work modality is responsible autonomy, which
emphasizes achieving objectives and productivity rather than focusing on physical location. It enables employees to decide the best way to execute a task, whether at the office or at home, as long as the job conditions permit it. Furthermore, exchange programs between personnel from different countries have resumed, with the aim of extending best practices to other company locations while giving participants the opportunity to learn about new cultures and enrich their professional expertise.

The shift towards this new way of working has brought about fresh challenges for both companies and employees. These challenges include managing teams that work remotely, adjusting to different forms of communication and collaboration, and ensuring information security. To address these

challenges, the company has expanded its training programs to cover topics like effective communication and intercultural leadership. Additionally, the cybersecurity measures have been reinforced to protect Ternium’s assets and any relevant third parties from potential risks or threats.


FORGING AHEAD: TERNIUM'S DRIVE TOWARDS INDUSTRIAL AND TECHNOLOGICAL EXCELLENCE

Ternium understands that the long-term success of the company depends on the continuous development of competencies and skills among its employees. This includes both existing staff and new hires. Additionally, Ternium focuses on effective planning for succession and ensuring smooth continuity processes.

To achieve these goals, Ternium has centralized the management of training activities and content across its various locations under the Ternium University team. They also collaborate with universities and educational institutions to foster partnerships and participate in collaborative projects within the company. This approach allows Ternium to effectively enhance the skills and knowledge of its workforce.

One of the main tools for implementing Ternium's vision for educational paths is the Ternium University platform. It is an online platform that enables employees to track their educational progress and choose from a wide range of in-house and external courses. In 2022, over 21,000 employees interacted with the Ternium University platform at least once, with monthly participation exceeding 13,600 participants. The tool has been well received by employees, with an average satisfaction rate of 4.2/5 points for the courses delivered.

To further emphasize the importance of training among employees, the company has established dedicated contexts for the development of new skills. In 2022, the Weekly Training Hour program was introduced for salaried employees, ensuring a minimum uninterrupted training time each week. Additionally, in early 2023, a pilot test of the Learning Week was conducted, offering a diverse range of courses delivered by external professionals. The participation level was highly satisfactory.
TERNIUM UNIVERSITY: SKILL

The company is constantly exploring innovative approaches to enhance the skills of its employees and foster a collective understanding of crucial subjects throughout its various divisions.

Ternium University's platform encompasses four fundamental pillars for the company's sustainable development in the long run: health and safety; quality and research and development (R&D); environment and diversity, equity, and inclusion.

Within the Ternium University platform, users have access to informative videos detailing the company's policies and procedures along with courses covering regulations and international standards, as well as interactive training sessions where participants can exchange knowledge and share their ideas and experiences.

Unlocking our Employees' Potential: Ternium's Training Programs for Employee Development

The company offers various programs that cater to different groups and job categories. For young professionals joining Ternium, there are specific programs designed to support their growth and development during the initial four years. These programs include the two-year Global Trainee (GT) program and the Global Professional (GP) program.

These programs offer customized training activities, both online and on-site, as well as networking opportunities. Participants are assigned to specific positions that help them develop expertise in desired fields. Networking activities encompass visits to industrial facilities across regions during the third and fourth years of employment, group interviews with the presidents of Ternium’s main markets and members of the Executive Committee to learn about their professional experiences at the company and their vision for its future, along with international assignments. To facilitate regional integration, all programs are simultaneously translated into English, Portuguese and Spanish.

Ternium’s senior employees with more than four years of experience can participate in the Senior Development Program, which covers topics such as industry 4.0, diversity and inclusion, along with other useful management tools. In 2022, the company resumed the High Impact Leadership Program (HILP)
a joint program between TU and IE Business School, based in Spain. This six-month program includes an international certification.

Additionally, that same year, the company launched two new programs: the Development and Mentoring Program (PDM) and the Global Leaders Executive Program. The first program emerged from an internal evaluation called "talent review" and is designed for middle and senior managers with high potential. The program focuses on three pillars: external coaching, where participants individually address current or future professional challenges; mentoring with top management, fostering open discussions and agenda; and an academic component with the IE university.
Meanwhile, the Global Leaders Executive Program is designed for top-level managers within the company and is conducted in collaboration with Wharton Business School at the University of Pennsylvania. This program is specifically designed to address current challenges and trends in the corporate world and provides practical knowledge and skills that can be applied directly in the industry.

Furthermore, Ternium collaborates with recognized universities in the countries where it operates to offer specialized second-cycle degrees in the field of steel industry to the employees. For example, in 2022, three individuals were sent to Sheffield University in England to complete a master's degree in metallurgy with full dedication and leave.


DRIVING EXCELLENCE: TERNIUM'S EFFORTS TO IMPROVE EMPLOYEE PERFORMANCE

Every year, Ternium carries out a formal performance assessment process to evaluate the individual performance of its salaried employees and managers. The results of these assessments influence various aspects of career development, including compensation, identification of training needs, and opportunities for enhancing performance. By implementing a performance assessment process that focuses on measurable objectives, the company aims to create a positive work environment and promote strong relationships between employees and their leaders.

Ternium’s performance assessment process is seamlessly integrated into the company’s human resources IT system, which encompasses each employee's objectives using a comprehensive 360-degree approach. This integration is a crucial component of the process as it aligns everyone's goals with the company's objectives
and guarantees transparency and fairness in assessing employees' work throughout the year.

To capture multiple perspectives, the performance assessment process incorporates various input sources, including the employee's self-assessment and client-supplier opinions. The complete process also includes the conformation of assessment committees as well as a feedback meeting to communicate the results of the evaluation and determine areas for improvement in the following year.

POWERED BY OUR PEOPLE: GROWTH THROUGH ENGAGEMENT AND FEEDBACK

The company regularly organizes interactive engagement, feedback, and communication events to provide opportunities outlining the company's strategy and its impact on employees' jobs. CEO live talks and from the presidents of Ternium’s business units, online town hall meetings, and Safe Hour meetings at the company's facilities are some of the mechanisms used to connect with employees and gather their perspectives on various matters.

Furthermore, Ternium regularly conducts confidential surveys to gather feedback from employees regarding their working experience, as well as their perceptions of the company's management, leadership, and culture. These surveys are designed to monitor employee satisfaction and provide insights for continuous improvement within the organization. In 2022, and for the first time, the survey targeted the Technicians and Operators group. The target audience exceeded 14,000 individuals, which presented a challenge due to the dispersed population and their focus on operational tasks. The process involved campaigns in dining areas, locker rooms, plant entrances, shared transportation, classrooms, and the utilization of technology to simplify access,
such as QR codes and the use of the HR ChatBot. The survey achieved an 80% response rate, with participants answering 17 questions, resulting in an engagement score of 87 points.

Based on these results, combined with the more than 6,200 comments received, action plans will be developed in the upcoming years to enhance employees' experience and foster a positive work environment.


INCLUSIVITY IN ACTION: TERNIUM'S DRIVE FOR EQUALITY AND FAIRNESS

Over time, Ternium’s workforce has become increasingly diverse, with employees representing 24 different nationalities with Mexican, Argentine, Brazilian and Colombian citizens constituting the largest portion of the company's team.

The company has implemented policies related to Human Rights, Diversity, and a Harassment-Free Work Environment. These policies serve as a guiding framework for talent management, attracting motivated employees, and cultivating an inclusive workplace. Ternium is dedicated to being an equal opportunity employer, striving to create a working environment that recognizes and nurtures talent from diverse backgrounds, encompassing different genders, nationalities, generations, cultures, religions, and experiences. This commitment is evident in the recruitment process, where specialized software is utilized to ensure a fair assessment of candidates based solely on their cognitive and technical knowledge. Moreover, to fill internal vacancies, Ternium employs an Opportunities Committee system. This process involves a specific time period during which all company members are informed of the vacancy, followed by an open application period. Subsequently, a committee consisting of members from various departments, supported by the HR Talent sector, convenes to make a final decision.

By implementing these policies and procedures, Ternium aims at creating a transparent and merit-based system that allows all employees to have equal access to career advancement opportunities within the organization.

Building Bridges for Inclusion: Our Efforts towards Equity

In its dedication to equity and inclusion, Ternium continually seeks out best practices and incorporates them into its policies and human resources programs.

The company's commitment to equality has been recognized by the Human Rights Campaign Foundation (HRC), which named Ternium as one of the best places to work for the LGBTQ+ community in Mexico for the third time in 2022. This certification evaluates the company's commitment to equality, taking into account its actions, policies, and procedures concerning equity, gender identity, sexual orientation, and inclusion.

Building on the success achieved since its inception six years ago, the HRC foundation is expanding its efforts to Argentina and Brazil. Ternium is actively working towards certification in those countries for the
upcoming years, further reinforcing its dedication to fostering inclusive workplaces.

In 2021, Ternium embraced the United Nations' Women's Empowerment Principles (WEPs). The company aims to increase female participation in management positions in the long term. To achieve this, Ternium is focused on enhancing the participation of women at the young professional recruitment stage, providing support to female employees throughout maternity to help them balance personal and professional objectives, and promoting greater female representation at the Board level. In 2022, Ternium witnessed a 26% increase in female employees under 30 years old within its salaried cluster and a 10% increase in women in managerial positions compared to the previous year. Additionally, as part of its commitment to the WEPs, Ternium encourages business practices that empower women throughout the steel industry value chain and the communities surrounding its facilities.


TERNIUM'S EFFORTS TO ACHIEVE EQUAL TREATMENT
In 2022, the company modified its policy regarding maternity, paternity and primary caregiver leave based on the conclusions drawn from an internal survey conducted a year earlier and the company's efforts to achieve greater equity among its employees.

The new policy establishes a minimum paid leave for primary caregivers, regardless of gender. Additionally, secondary caregivers are entitled to a similar benefit.

The company policy also provides that new parents may work from home three times a week and two times in the office during the first year following the corresponding maternity, paternity, or adoption leave, as described above.
Recognizing the importance of work-life balance and gender equality, this policy aims to support individuals in their caregiving responsibilities, irrespective of gender. These measures help create a workplace culture that values and supports the diverse needs and roles of its employees, fostering a more harmonious and equitable society overall.

Creating an Inclusive Workplace: Ternium's Drive
for Diversity & Equality

In 2019, Ternium introduced the Maternity Mentoring program as a part of its efforts to address the gender gap and promote women's advancement into managerial roles. The program focuses on supporting women's career development and reducing the rate of female employees leaving the company after pregnancy or maternity leave. Through this initiative, employees and their leaders receive guidance and assistance in planning and managing the transition before, during, and after maternity leave. The program is currently implemented in Mexico, Argentina, Brazil, and Guatemala, with the support of a specialized consultancy firm.

As part of Ternium’s Diversity+ program, the Lean In Together initiative was also launched in 2019. This project aims to raise awareness and foster discussions about important topics related to inclusion and diversity, including unconscious biases, sexual diversity,
gender identity, and the relevance of intercultural and inclusive leadership. The Lean In Together circles provide a safe and open space for participants from diverse regions, genders, professional backgrounds, and expertise to freely express themselves and engage in thoughtful dialogues on these matters. In 2022, the fourth generation of Lean In circles was launched, with the community growing to more than 600 participants including 18 company directors and expanding to all Ternium locations. Additionally, specific discussions on gender equality and generational interaction were reinforced, involving participants from previous stages of the program.

Ternium strongly believes that creating a safe and inclusive work environment is crucial for improving employee performance. The company also recognize that having a diverse workforce brings about innovative solutions to address modern challenges. As a result, Ternium considers these initiatives as essential elements of their ongoing agenda and will continue to prioritize them in the future.

TERNIUM'S INDUSTRIAL PROJECT IS ANCHORED IN OUR COMMUNITY´S DEVELOPMENT

At Ternium, we firmly believe that the company's industrial project is only possible if the communities where we operate develops alongside it.

We look for inclusive growth and development in the communities where we work and live, promoting a culture that rewards merit and encourages enterprise, both academic and in terms of personal effort. This principle guides the implementation of the community programs tailored to the needs of each community, and based on the promotion of education, culture, volunteering, health and social welfare, and environmental care.

In 2022, the company increased its investment in community programs to $21.2 million, representing a
22% increase from the previous year. The growth was primarily driven by new projects in the education area, which the company believes is critical in promoting equal opportunities for individuals along with social progress. In 2022, 85% of the company’s investment in community programs targeted this area. By investing in the well-being of the communities it serves, Ternium aims to create a better future for everyone.


EMPOWERING CHANGE: THE TRANSFORMATIVE
ROLE OF EDUCATION

Over the years, the company has developed educational programs covering the entire school cycle, from elementary to post-graduate, helping children and youngsters fulfill their potential and become active contributors to society.

These programs have a strong emphasis on technical skills and innovation, with a specific focus on developing STEM skills (Science, Technology, Engineering, and Mathematics), socio-emotional skills, and literacy in children and youth.

In 2022, the education programs underwent a rebranding in honor of Roberto Rocca, one of the founders of Ternium and the Techint Group, as a tribute to his legacy and values. The programs were renamed as the Roberto Rocca Technical Schools (ETRR), Roberto Rocca Technical Gene, Roberto Rocca After School Program, and Roberto Rocca Scholarships. Additionally, the Roberto Rocca Educational Campus was launched, offering free training opportunities to the public in a modular and personalized learning environment. Furthermore, June 10 was designated as Global Education Day, an annual celebration to emphasize the significance of education for Ternium and its sister companies within the Techint Group.
Creating value through Technical Education

The Roberto Rocca Technical Schools (ETRRs) are a network of technical schools within the Techint Group created with a long-term vision of providing advanced technical education in communities near the companies' production facilities.

Ternium built its ETRR in 2016 in the city of Pesquería, in the State of Nuevo León, Mexico, with an investment of $32.6 million and a capacity for 384 students. The aim of the ETRR is to enhance the abilities of young people in the region, promote employability in industrial activities, and facilitate social mobility. The project was positively influence by the experience of our sister company Tenaris which had built the first ETRR in Argentina in 2013.





THE IMPACT OF CREATING NEW LEARNING ENVIRONMENTS
In 2022, the project to redesign the common areas of ETRR began, aiming to accommodate a larger number of participants in educational activities following the expansion of our learning initiatives to the wider community.

The new spaces are designed to encourage creativity, collaboration, and the inclusion of
students, teachers, and professionals from the community who take courses at the ETRR.

The project includes the revamping of underutilized common areas, administrative offices, and green spaces on campus and incorporating technology tools to improve the learning experience. The project is expected to be completed by 2025.

Mechatronics Project Workshop: Student Operating Robotic Arm with Advanced Vision System at ETRR Pesquería, Mexico.
The Pesquería ETRR covers high school education from the ages of 15 to 18 and all students receive financial assistance based on their individual needs, through scholarships covering an average of 96% of the total educational costs. In July 2022, 117 students graduated as part of the fourth generation and 74%of them are either working or continuing their studies. Some graduated students were also beneficiaries of the Roberto Rocca University Scholarship program to further their education.

The educational model is based on the High-Tech-High Schools in California (United States) and the PBL Works organization, with a strong focus on STEM. One of the key components of the Project Based learning methodology is the presentation of STEM projects at
student science fairs. In 2022 ETRR students presented 291 STEM projects with particular emphasis on designing technological devices for residential installations, aimed at helping households generate significant energy savings.

The ETRRs students also participated in prestigious international competitions, including the FIRST LEGO League International Open Brazil robotics competition in Rio de Janeiro, Brazil, and the Expociencias and Mexican Science and Engineering Fair in Mexico. Notably, two of the presented projects won first place at the Mexican Science and Engineering Fair, with another receiving a special mention.

We also place a strong emphasis on providing continuous learning opportunities for the ETRR teachers. In line with this commitment, during 2022 more than 21 teachers participated in a comprehensive training program that provided them with 4,574 hours of instruction in topics like technical training in Allen Bradley and Siemens PLC Programming, bilingual education, mathematical thinking, project-based learning, active learning.

ETRR's completion rate of 94% reflects the institution's unwavering commitment to technical education and student engagement. To ensure continuous improvement, the school regularly seeks feedback from students, parents, teachers, and staff via surveys on various aspects of management and school climate. The 2022 survey had an average positive rating of 79% and showed an increase of 6% in responses from the previous year. These results serve as a valuable tool for ETRR's management team to develop future action plans and continue to elevate the school's standards.

Practical Skills for Students and Communities: Technical Education in Action

The ETRR also serves as a bridge between students and the industry. In 2022, a total of 95 final-year students participated in internships in 11 companies within the region, taking their initial steps into the professional world. Out of these, 50 students were assigned to internships at Ternium, all of them specifically focused on technological innovation.

The purpose of this initiative is to gradually integrate students into the job market, allowing them to solve real problems in a controlled environment under the supervision of both the company and the technical school. For instance, one student participated in the development of a wireless gas leak detector, which can accurately identify and locate leaks within the plant, ensuring the safety and well-being of the workers.

As part of its commitment to the community, the company is continuously working towards consolidating the ETRR as an integral part of the local educational system, providing support to the community at large. In 2022, the ETRR achieved a historic milestone by becoming the first certification center for SolidWorks and FESTO in the state of Nuevo León, Mexico.
RESPONDING TO THE GROWING NEED FOR TECHNICAL EDUCATION

In early 2023, Ternium announced its plan to build a technical school in Santa Cruz, Brazil, near its slab production facility. The goal is to provide advanced technical education to over 600 young people in the community. The school's curriculum will focus on providing industry-specific skills and knowledge to equip students for successful careers in the manufacturing industry. With a proximity to Ternium's production plant, the school will provide practical training opportunities and access to real-world experience.

The Technical School is expected to become operational in 2025 and will serve as a significant step in Ternium's commitment to promoting education and human development in the countries where it operates. The company's investment in education is a testament to its belief in the importance of empowering local communities with the tools and knowledge necessary for their successful development.

With this new initiative, Ternium seeks to help bridge the skills gap and provide a pathway for future professionals in the manufacturing industry.

Quality Technical Education Made Accessible Through Public-Private Partnership

The Roberto Rocca Technical Gene program provides public technical schools with infrastructure and equipment, as well as teacher training and on-the-job training internships for high-school students, leveraging the teaching and learning practices and concepts developed in the Roberto Rocca Technical School program.

In order to provide students with the appropriate equipment to enhance their classroom experience, foster connectivity, and strengthen their technical skills, during 2022, Ternium provided Technological classrooms, Robotics and Industrial Automation classrooms, and a Computing, Construction, and Digital Design laboratory to public technical schools in Ramallo and San Nicolas in Argentina. Students enrolled in the Master Builder program at one of the public technical schools will have access to digital design and rendering tools through the latter initiative. Additionally, the Computing program will provide opportunities for students to develop their coding skills and improve their teamwork abilities.

As part of these building improvement projects, the company furnished common areas for recreational and cultural purposes, such as gyms, as well as administrative spaces like offices, teaching rooms, and psycho-pedagogical support cabinets, which added up to more than 2,500 m2 (approximately 27,000 square feet) of construction. The technical school in Santa Cruz, Brazil, also benefited from similar projects with the upgrading of two laboratories.

In collaboration with FESTO and local universities, students and teachers were provided with training and certification in the areas of Pneumatics, Electropneumatics, and PLC (programmable logic controller) programming. In 2022, 100 students from schools in Ramallo and San Nicolas in Argentina received training on these topics in the laboratory donated by Ternium to the National Technological University (UTN), while 62 students from the public technical school in Santa Cruz were able to receive training in Cefet-Itaguaí.

During the participation process, the companies' processes were compared to a specially designed Management Model that covers various aspects of business management, such as leadership, resource and personnel
management, and results. Both companies received recognition for their outstanding business models, which serve as proof of the effective utilization of tools developed through the ProPymes program over the years.


PROPYMES NEW ENVIRONMENTAL PROGRAM

ProPymes Environment is a newly introduced program designed to encourage companies in our value chain to implement environmental transformation measures within their production setup, in order to meet future demand expectations. The program's training is centered around understanding global commitments, current regulations, and quality frameworks. It also focuses on identifying key management indicators and promoting environmentally friendly products and processes.

The main goal of this program is to collaborate with SMEs to raise awareness about the significance of adopting greener operational practices. Additionally, ProPymes aims to provide tailored assistance to each SME based on their specific needs, with the ultimate aim of achieving environmental improvements.

In 2022, Propymes collaborated in Argentina with the ITBA (Buenos Aires Institute of Technology) to organize several sessions focusing on various environmental strategies, including topics like recycling, circular economy, and reducing carbon emissions from operations. Additionally, we developed an energy efficiency program in partnership with the INTI (National Institute of Industrial Technology), consisting of six workshops specifically tailored for plant supervisors and managers. The objective was to create working teams to measure energy usage with a customized spreadsheet provided by INTI. The ultimate goal was to generate ideas for energy efficiency improvements related to people's behaviors rather than costly investments, which required an active participation and a cultural shift in the way the issue was being tackled. Ultimately, the aim was to include energy efficiency and CO2 emissions within the production performance indicators.

ENHANCE SUSTAINABILITY ACROSS OUR VALUE CHAIN
In 2022, ProPymes carried out its first "Sustainability in the Value Chain" program. This program was delivered by professionals from the Buenos Aires Institute of Technology (ITBA). It attracted 29 participants representing 25 small and medium-sized enterprises (SMEs) from Ternium's or its related companies' value chains. The main objective of the training program was to introduce sustainability tools specifically designed for SMEs.

The participants learned about effective environmental management in the industry, environmental licenses, and the ISO certification process. They also gained an understanding of the challenges arising from climate change in their sector and developed strategies to address these challenges.
The program emphasized the importance of adopting a proactive sustainability agenda. It explored the potential of the circular economy and encouraged participants to take actions that contribute to continuous improvement as a way to generate added value for their businesses.

FINANCIAL ASSISTANCE

The financial assistance service is divided into two main components. The first is direct assistance, which provides support for investments aimed at improving productivity and expanding the operational capacity of small and medium-sized enterprises (SMEs). This assistance is designed to help SMEs enhance their financial capabilities and efficiency.

The second component involves collaboration with banks and other financial institutions to offer financial solutions specifically tailored for SMEs. This coordination aims to provide SMEs with access to the necessary financial resources they require to meet their business needs and objectives. Leveraging long-standing relationships with banks and financial institutions, the intention is to facilitate and streamline the process of obtaining financial support for SMEs.

COMMERCIAL SUPPORT

ProPymes assists suppliers in the development and certification of new products for Ternium and/or any of its related companies. In addition, it assists SMEs in the process required to become a supplier of large companies, in order to attract new customers from the automotive, oil & gas and other industrial sectors. ProPymes also offers SMEs the possibility of leveraging on the Techint Group’s global network of commercial offices in order to enhance their exports market reach.

One of the success stories of the ProPymes program in Mexico is a Ternium´s customer that is located in the state of Puebla and specializes in manufacturing and supplying various carbon steel wires to different industries, including automotive.

Thanks to the program, this company was able to expand its product offerings, reduce reliance on imports,

TERNIUM'S COLLABORATION FOR COIL TRANSPORTATION INNOVATION

Through the ProPymes program in Mexico, Ternium actively participated in the development of a specialized coil transportation platform in collaboration with the Automotive Cluster of Nuevo León (CLAUT) along with two logistics services companies. This innovative platform enables the transportation of 35-ton coils.

Known as the "Big Coil," this new trailer model revolutionizes the efficiency of coil transportation, especially for the heavier coils produced at Ternium's new hot rolling mill in Pesquería. By reducing the number of trips required, this solution not only increases efficiency but also contributes to a significant reduction in CO2 emissions.

This initiative showcases Ternium's commitment to sustainability while also paving the way for small and medium-sized enterprises to access new markets. It represents a successful collaboration between different stakeholders to address industry challenges and promote sustainable solutions.

and expand its international presence. Their carbon steel wires are now integrated into exhaust systems, seats, safety components, and hood support rods of vehicles manufactured in Mexico, the United States,
and Argentina.

Another successful case within the program is a company that provides the pulpits used in Ternium’s industrial facilities. Prior to the program, Ternium had to import these pulpits from Asia. With the support of ProPymes, this company experienced a significant growth, becoming a reliable local supplier for Ternium and other companies thus replacing imports. In 2022,
it was recognized as one of the SME of the Year at the annual ProPymes event in Mexico.

Special program for export-led companies

Under the ProPymes Exporta program, launched in 2018, the company encourages export-led SMEs to expand their businesses abroad. Selected companies in the steel industry´s value chain in Argentina are invited to participate according to their export profile. The program aims at increasing their medium-term export capabilities through a broad industrial, commercial and institutional support program. In addition, the company finances SMEs' purchases of steel used in the manufacture of their export products.


INSTITUTIONAL INITIATIVES

The ProPymes institutional assistance program supports small and medium-sized enterprises (SMEs) in various ways to strengthen their connections with government entities and communities, and to address shared concerns. This program includes initiatives such as developing strategies to ensure fair competition in the local market, especially in response to the potential impact of unfairly traded imports. It also involves collaborating with industry chambers to establish technical standards for industrial products. Additionally, the program focuses on enhancing the competitiveness of SMEs, implementing measures and activities aimed at improving their overall performance.

The ProPymes program also promotes the participation of SMEs in major national events, allowing them to

In Mexico, the ProPymes event is biannual and includes awards for SMEs excelling in quality or safety certifications, capital expenditures, import substitution, export promotion and its trajectory within ProPymes programs.

In Argentina, the annual event features panels and interviews designed to allow SMEs’ executives share their experiences and lessons learned. During the 21st ProPymes Seminar in Argentina, we conducted a live demonstration of the steel framing construction system, which is based on steel. In just 4 hours we assembled a complete structure of a 60 m2 house, showcasing one of its key advantages: the rapid construction speed compared to traditional systems based on bricks and cement.


THE ROBERTO ROCCA TECHNICAL GENE INITIATIVE

In early 2013, Ternium’s community program, the
Roberto Rocca Technical Gene, expanded its reach to
the value chain through ProPymes. The goal was to inspire Ternium’s customers and suppliers to adopt the technical schools assistance model in their nearby communities.

The Technical Gene program operates on the belief that industrial companies play a crucial role in promoting high-quality technical education and fostering a long-term industrial culture, serving as a bridge between young individuals and employment opportunities within the industry. The program focuses on training teachers and facilitating student internships in SMEs.

Additionally, the Technical Gene program aims at enhancing the educational infrastructure and equipment of technical schools within the sphere of influence of these SMEs. As of the end of 2022, the program had engaged 45 technical schools in various locations and was receiving support from multiple companies.

EXPOAGRO FAIR IN ARGENTINA
Ternium supports local organizations and events that
foster technological advancements and promote
the adoption of sustainable production practices
in its target markets. Recently, the company sponsored an award during the ExpoAgro fair in Argentina. The award recognizes innovative projects focused on boosting productivity and operating in an
environmentally sustainable manner.
The award ceremony was held as part of the larger ExpoAgro event organized by the agribusiness sector. This sector plays a significant role in the country's GDP and accounted for 9% of Ternium's shipments in Argentina in 2022. Ternium's sponsorship of such initiatives reflects its commitment to driving progress and sustainability in the industries it serves.

Business conduct compliance program

Ternium has appointed a Business Conduct Compliance Officer (BCCO) reporting to the CEO and the Audit Committee, who has the responsibility of identifying and preventing possible corruption risks and promoting a culture of ethical and transparent conduct, and for designing, implementing and supervising the Compliance Program, aligned with the requirements of applicable national and international laws against corruption and bribery, such as the US Foreign Corrupt Practices Act and the 1997 OECD Convention on Combating Bribery of Foreign Public Officials.

Ternium developed its Business Conduct Compliance Program (BCCP) with the objective of preventing bribery and mitigating corruption risks. The BCCP is aimed at promoting the implementation of business conduct best practices, both internally and when interacting with customers, suppliers, state-controlled entities and other third parties. The BCCP is focused on ten core preventive measures: risk assessment, normative framework, communication, advisory, training, acknowledgement, monitoring and auditing, third party due diligence and monitoring, disciplinary actions and remediation, and benchmarking.

In order to define the scope of application and concentrate efforts, sensitive functions are identified based on a risk matrix that takes into account the type of operation, the country of operation, and/or the involved parties. Individuals occupying or performing these functions generally become the focal point of the corporate compliance program activities. However, regardless of the aforementioned, all Ternium employees are obliged to acknowledge and adhere to the guidelines of the Code of Conduct upon joining the company.

Ternium’s Code of Conduct and Policy on Business Conduct explicitly prohibit any form of illegal payment and strictly enforce a zero-tolerance policy. The documents also provide detailed guidelines for conducting due diligence when engaging third-party representatives on behalf of Ternium. Internal procedures govern charitable contributions and hospitality expenses extended to third parties, such as meals, gifts, and business trips. Facilitating payments are strictly prohibited.
Ternium’s Compliance Program is aimed at promoting the implementation of business conduct best practices, both internally and when interacting with customers, suppliers, state-controlled entities and other third parties.








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 agents, 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 BCCP and the investigation of any conduct contrary to the Policy on Business Conduct or its principles.

The company also closely monitors potential conflicts of interest that may arise with its employees. These conflicts can manifest in various forms, such as when an employee has personal interests that could influence their decision-making in favor of their own interests rather than those of the company. They can also arise in situations where a person has relationships or financial ties with other parties that could compromise their objectivity, such as when making hiring decisions,

conducting business transactions, or making investment choices.

In September 2022, a new conflict of interest disclosure campaign was launched with the intention of updating
the status of company employees. In those cases where an affiliation with public officials is formally declared, the Human Resources team involves the Business Conduct Compliance sector to assess whether the employee's duties can be carried out without compromising the company's interests.

The company recognizes the significance of effective communication in cultivating an ethical culture within the organization. The company places a high priority on maintaining constant communication with directors, senior managers, and employees to enhance their understanding of compliance risks and the importance of adhering to applicable principles and regulations. This comprehensive program encompasses various communication methods, including top-down messages, management meetings, newsletters, articles, and intranet announcements.

Ternium encourages active participation from all departments and emphasizes the value of seeking guidance when encountering red flags or ambiguous situations. By fostering open communication and promoting awareness, Ternium aims to strengthen its ethical framework throughout the organization.

Training on anti-bribery policies and procedures

Ternium has implemented an extensive training program on anti-bribery policies and procedures. This program aims at training Ternium’s employees on the company’s ethical commitment along with providing a clear set of guidelines and values. Eligible employees have to complete a mandatory e-learning course that includes the resolution of practical cases and a final evaluation and, according to their level of exposure, participate in an on-site or live training workshops as well.

99.4% of Ternium’s eligible employees have completed the mandatory training course on the company’s Policy on Business Conduct in e-learning format. In 2022, Ternium delivered 62 live training sessions with 517 participants in total. Our anti-bribery training program
also reaches third parties that represent or act on behalf of Ternium. 913 third-party’s employees have completed Ternium’s mandatory training program on corruption prevention, which has been implemented in e-learning format.


SUSTAINABLE SOURCING AND STRONG SUPPLIER GOVERNANCE

Ternium makes most of its purchases through Exiros, a specialized procurement company owned 50%/50% with Tenaris. Ternium’s suppliers undergo, through Exiros, a rigorous selection process to ensure that adequate governance standards are in place, in compliance with applicable laws and regulations and in line with the company’s Code of Conduct for Suppliers, which includes, among other items, ethical behavior, compliance with the law, and health, safety, human rights and environmental management commitments.

In early 2023, Ternium’s Board of Directors approved a sustainable sourcing policy to uphold ethical standards throughout the company's value chain. This policy encompasses various principles, including compliance with the law, ensuring a safe work environment, respecting fundamental rights and human dignity, promoting diversity, rejecting all forms of discrimination, protecting the environment, addressing climate change proactively, safeguarding Ternium’s and related parties' information and assets, and implementing corporate governance practices for ethical behavior.

Compliance with these principles will be monitored, considering the nature of the business relationship with Ternium, and will be taken into account when entering or renewing agreements. The goal is to promote responsible practices and ensure that sustainability and ethical considerations are integrated into Ternium’s value chain operations.

Conflict Minerals Reporting Requirements

Ternium has implemented a Procedure for Compliance with Conflict Minerals (sourced from regions characterized by armed conflict and human rights abuses), which includes an annual request to suppliers in the form of the "RCOI Form." This form aims at determining

whether any conflict minerals necessary for the functionality or production of Ternium’s products, whether manufactured by Ternium or by third parties contracted by Ternium, may have originated in a Covered Country. All responses to the RCOI Form are thoroughly reviewed by Ternium. If necessary, potential conflict minerals suppliers are asked to provide additional information or clarifications.

Only a negligible portion of Ternium’s products (representing less than 2% of the company sales) may contain conflict minerals. In 2022, Ternium identified and surveyed 38 potential conflict minerals suppliers. As of the present date, 100% of the surveyed potential conflict minerals suppliers have confirmed that none of their products, including raw materials, contain conflict minerals originating from a Covered Country.

In addition to the RCOI Form, the Policy incorporates conflict-minerals-free-sourcing clauses, which have been included in Ternium’s General Terms and Conditions for the Purchase of Goods and Services.

Based on the information obtained through the aforementioned procedures as of the present date, Ternium has no reason to believe that any products manufactured by Ternium or contracted by Ternium to be manufactured by third parties contain conflict minerals necessary for the functionality or production of such products that have originated from a Covered Country.

For more detailed information, please refer to Ternium’s SD Form submitted to the SEC on May 11, 2023.


COMPLIANCE LINE

Ternium has established and encourages the use of its Compliance Line. This confidential channel is available to all employees, suppliers, customers and other stakeholders who wish to report any type of alleged breaches of the Code of Conduct and Ternium’s policies. The Compliance Line is managed by the Company’s Internal Audit Department, which is independent of the operating areas, under the supervision of the Company’s Audit Committee.

The identity of the reporting person and the reported fact itself remain confidential as long as it is so permitted by applicable laws and regulations. Ternium takes action, as necessary, to avoid retaliation against those who use the Compliance Line in good faith. Ternium’s Compliance Line is available in Spanish, Portuguese and English. Reports may be submitted in person, online, by email or through our toll-free numbers available in most of the countries where Ternium operates.

In February 2022, the Company enhanced its Compliance Line in accordance with best market practices, technological developments and applicable regulatory requirements. For example, the new system facilitates the submission of complaints (including the possibility of reporting from a mobile device by scanning a QR code) and allows for interaction with the reporting person.

The renewed Compliance Line was publicized, accompanied by a communication campaign in all Ternium operating locations.

Compared to previous years, complaints submitted during 2022 have significantly increased. In 2022, 47% of analyzed complaints were substantiated and resulted in corrective actions, including dismissals, termination of commercial relationships and improvements in the Company’s internal control environment. 38% of complaints were related to workplace environment matters.

Shareholders’ compliance line

In addition, Ternium has a web-based confidential channel for investors to communicate their concerns directly to the company’s Audit Committee, which
regularly reviews the status of all reports received through this line with the assistance of our Internal Audit Director.


RISK MANAGEMENT

Ternium has established a Critical Risks Committee (CRC), which reports to the company’s CEO. 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 ensuing action plans. Critical risks are escalated through the usual reporting lines and decision-making is the responsibility of managers.

The company has categorized risks according to the potential area impacted, the likelihood of their occurrence and the severity of a potential impact. The main identified risks include threats to the proper operation of machinery and processes, cybersecurity and environmental issues. The CRC also assesses climate change risks and mitigation plans are defined as needed.


TERNIUM'S PROACTIVE APPROACH IN THE FACE
OF GROWING CYBER THREATS

Ternium recognizes the escalating risk of cyberattacks in the current digital landscape, particularly the growing prevalence of ransomware attacks. In response to this concerning trend and the regulatory actions implemented by agencies in the U.S. and EU, Ternium has taken proactive measures to enhance its cybersecurity defenses. The company is committed to fortifying its systems and protecting against potential threats, ensuring the safety and integrity of its digital infrastructure. By prioritizing cybersecurity, Ternium aims to mitigate risks and maintain the trust of its stakeholders in an evolving and challenging cybersecurity landscape.

Ternium is focused on protecting the company and its stakeholders against information security breaches and cyber-attacks, has implemented various controls at different stages. The first stage involves using firewalls as perimeter controls to prevent unauthorized access to Ternium’s systems by external parties. To enhance this control, the company has engaged a specialized SOC IT/

OT (Security Operation Center) service to monitor the systems in real-time, ensuring the continuous effectiveness of their control measures. In the event of security incidents, Ternium promptly conducts thorough analyses of all their equipment to identify and isolate any threats, thus minimizing any potential negative consequences for the company.

Regarding internal users, Ternium has defined access profiles for different systems based on each position. Whenever a user requests access to a system or application, or when there is a need to modify their IT profile due to a position change, the Compliance sector carries out compatibility, segregation, and competence controls between the user's role and the requested access.

Ternium has taken significant measures to enhance its cybersecurity defenses and effectively address potential risks. Through strengthened controls, robust processes, and proactive procedures, the company has better positioned itself to monitor, detect, and respond to hacking, malware infections, cybersecurity breaches, and related threats. The company has also launched awareness campaigns and conducted ethical phishing exercises to strengthen its resilience against cyber threats. Regular training sessions for executives and employees have been implemented to improve their capacity to recognize and report potential cybersecurity incidents.

Of all the cybersecurity incidents that were detected in 2022, only eight were highly sophisticated and all of them were contained. None of the attacks led to any known breaches of Ternium’s business-critical IT systems and, as such, did not result in any material business impact.

GRI CONTENT INDEX
In this section, Ternium presents the economic, environmental, and social topics that have been prioritized for inclusion in our Sustainability Report. These topics are reported in reference to the Global Reporting Initiative's (GRI) Standard.

Ternium conducted a materiality analysis in 2019 to establish a consistent reporting framework for a minimum five-year cycle, following GRI's four-step process. This involved identifying key economic, social, and environmental topics through industry research, benchmarking, international standards, and priority subjects. These topics were then prioritized through a consultation process involving employees, suppliers, customers, community organizations, business associations, investors, press, and academic institutions.

To finalize the selection of material topics, the results were examined in light of the company's long-term strategy and implemented programs. This analysis produced a materiality matrix that ranks relevant economic, environmental, and social topics based on their impact on stakeholder assessments and decisions, as well as their significance to the company. The Materiality Matrix has been included in the company’s sustainability report for the year 2019, on page 90.

Additionally, the included topics are annually reviewed with senior directors to consider any new interests that may arise through the interactions with various stakeholders:

Employees: We prioritize transparent communication through feedback check-ins, town hall meetings, surveys, and performance reviews. In 2022, our CEO held four Live Talks followed by Q&A sessions, allowing employees to ask questions. We hosted Ternium’s Safety Day for employees and managers to discuss safety issues and improve operations.
Customers: We actively engage in dialogue with our customers to understand their needs. Through long-term partnerships, we create opportunities for supply chain and digital integration. In 2022, some customers requested our participation in sustainability surveys and CSR audits. They also sought information on Ternium’s sustainability performance for benchmarking using systems like CDP or EcoVadis.

Suppliers: We closely engage with our suppliers to strengthen the steel supply chain. Our ProPymes program plays a key role in this endeavor. Moreover, our procurement entity Exiros, jointly owned by our sister company Tenaris, provides valuable insights on suppliers' key concerns and priorities.

Communities: We establish ongoing communication with local communities near our main facilities. This includes organizing face-to-face gatherings led by our area managers and creating dedicated social media platforms for each community, actively encouraging them to express their concerns and informing them about pertinent operational updates.

Investors: We actively engage with shareholders through regular communication via conference calls, meetings, and anonymous feedback. This ensures information exchange and keeps us updated on emerging trends.

Industry Associations: our involvement in industry associations enables collaboration with peers to address common challenges, share best practices, and establish unified standards for the steel industry's future.

CHAIRMAN´S LETTEROUR SUSTAINABILITY JOURNEY
NOTES

1. % of employees and contractors working at ISO 14001 certificated facilities. Distribution centers and corporate offices are not included in the scope.

2. Mining operations certified with ISO 14001
Mining Operations certified with ISO 14001 scope includes: Aquila mine, Tecoman Transference station and Alzada Pelletizing Plant.

3. Energy and emissions     
The energy and emissions data presented herein are limited to Ternium's steelmaking facilities and are based on worldsteel's sectoral approach methodology. Carbon dioxide (CO2) emissions are the only greenhouse gas emissions reported, given the non-significant emission levels of other greenhouse gases within Ternium's processes.
Scope 1 was calculated using Tier 3 emissions factors based on specific site measurements on the main raw materials performed by Ternium. CO2 captured and sold to other industries are considered as emissions avoided.
Scope 2 emissions were estimated using location-based (Tier 2) and market-based (Tier 3) emission factors where applicable, but without accounting for clean energy certificates. If the clean energy certificates were taken into account, they would result in 1.12 million tons of CO2 and 0.11 tons of CO2 per ton of crude steel for scope 2.
Scope 3 emissions were calculated using Tier 1 and Tier 3 emission factors based on upstream emission factors provided by suppliers. It only includes category 1: purchase of good and services. The Blast Furnace slag sold to other industries is considered as emissions avoided.
The percentage of gross global scope 1 CO2 emissions subject to GHG emissions regulations or programs in 2022 was 39%.
The energy intensity ratio and total energy consumption metrics account for all energy sources used, including fuels, electricity, and the energy required for feedstock production.
Worldsteel methodology has been published as an International Standard, ISO 14404:2013 - Calculation method of CO2 emission intensity from iron and steel production. It consists of Part 1: Steel plant with blast furnace, Part 2: Steel plant with electric arc furnace (EAF) and Part 3: Steel plant with electric arc furnace (EAF) and coal-based or gas-based direct reduction iron (DRI) facility.

4. Fuel Consumption
Fuel consumption includes fuel like natural gas, fuel oil, light oil and reducing agents like coal, coke and natural gas.
"Renewables" refers to fossil free biogas. "Other fuels" include light oil and heavy oil.
Figures in 2021 were restated because they included energy from feedstocks for 20,556 TJ.

5. GHG Emissions
Emissions under GHG Protocol methodology: Ternium’s total emissions calculated under under GHG Protocol methodology were 19.28 million metric tons of CO2eq for scope 1 and scope 2 market-based, and 6.35 million metric tons of CO2eq for scope 3 (that includes the procurement of goods and services such as steel purchases for all the operations, and upstream and downstream transportation, and employee travel only for Ternium Brasil).
Emissions from operations related to steel production and transformation were 16.94 million metric tons of CO2eq for scope 1 and scope 2 market-based, and 6.34 million metric tons of CO2eq for scope 3 (which includes the procurement of goods and services such as steel purchases for all the operations, and upstream and downstream transportation, and employee travel only for TX Brasil). Ternium´s specific emission for crude steel production resulted in of 1.44 t CO2e/t crude steel (S1 + S2) and 1.61 t CO2e/t crude steel (S1 + S2 + S3).
These figures include CO2, CH4, N2O, HFCs, PFCs, and SF6. The 2022 corporate inventory was third-party verified, using 2018 as the baseline year for all sites where it has operational control. Offices and service centers are excluded due to their low significance (<1% of the company's electricity consumption).

6. Dust emissions - Particulate matter / Oxides of nitrogen (NOx)
The information about Dust emissions - Particulate matter and Oxides of nitrogen (NOx) corresponds to steelmaking sites excluding power plants and includes only stacks emissions. Reports submitted to local authorities were used to calculate these emissions based on estimates and direct measurements.

7. Water
All water management figures are obtained from measurements and estimated calculations and defined for Ternium´s steel business excluding mining operations.
Ternium's water management strategy is designed on a case-by-case basis. Ternium's facilities in Mexico and Guatemala are located in water-stressed areas while steelmaking facilities in Argentina, Brazil, Colombia and United Sates have high surface water availability.
Regarding Ternium's water intake, excluding power plants, reused water from the power plant located in Argentina is being considered, which accounted for 116 million cubic meters in 2022, representing 91% of its total intake for steelmaking.
The percentage of water withdrawn in regions with high or extremely high baseline water stress is calculated as the total water withdrawn in areas with high water stress divided by the total water withdrawn by Ternium excluding power plants.
The percentage of water consumed in locations with High or Extremely High Baseline Water Stress it is calculated as the total water consumed (withdrawal – discharge) in areas with high water stress divided by the total water consumed by Ternium excluding power plants.
Consumption is defined by Worldsteel as the difference between water intake and discharge. The quality of the
discharged water is monitored in accordance with local regulations in each country where Ternium operates.
Freshwater is water with concentration of total dissolved solids equal to or below 1,000 mg/L.

8. Water Management at Mexican facilities
Third-party water is mainly sewage water from external wastewater treatment plants or directly sourced from the city's drainage.
In 2022, less than 1% of the Mexican facilities' water intake from third parties was potable water.
Water intensity includes both the water extracted and the water recirculated within the system. Excluding recirculated water the 2022 figure is 3.1 m3 per ton of crude steel.

9. Materials and waste
The information about materials and waste only refers to Ternium's steelmaking facilities except for the information about mining tailing waste.
Total waste generated in 2022 was 102.5 thousand tons from which 15% were Hazardous. As part of our strategy to minimize the amount of total waste sent to final disposal, Ternium sends 11% of its total waste for reuse and/or recycling. All waste is reused, recycled, treated and / or disposed offsite.
To classify each type of waste, national regulations applicable to each site were considered. The destination of each type of waste is reported according to the treatment applied by each supplier.
In 2020 and 2021, some co-products/recover materials from Brazil steelmaking site were included as non-hazardous waste sent to recycling, as of 2022 are reported within co-products.
Non-hazardous waste diverted to landfill disposal in 2021 shows an increase due to inert construction waste from works in Brazil and Guerrero steelmaking sites.

10. Material Efficiency equals crude steel plus co-products divided in crude steel plus co-products and waste. Waste equals the material sent to landfill plus material sent to incineration.

11. Steel scrap recycled Includes both home carbon steel scrap and purchased carbon steel scrap.

12. Mix Rock® & other mixes supplied to the cement industry are generated by the electric-arc furnaces at Guerrero and Puebla sites in Mexico.

13. Mining tailing waste. The information regarding mining includes 50% of Consorcio Minero Benito Juárez Peña Colorada S.A. de C.V

14. Headcount
External employees include mostly contractors of the production facilities.
In late 2021 the company restructured job positions according to the level of responsibility and market benchmark. In consequence historical headcount figures of

15. Headcount / Diversity of governance bodies and employees
In late 2021 the company restructured job positions according to the level of responsibility and market benchmark. In consequence historical headcount figures on salaried and managerial KPIs for the years 2021 and 2020 were restated.

16. Average hours of training per year per employee
During 2022 the company delivered 867,081 hours of training to 21,488 full-time employees and 24,357 hours to 308 external people. Training does not include on-site coaching by supervisors (on the job training).
Given the restructure in job positions, 2021 figures were restated. Figures for 2020 remain as previously published given data limitations.

17. Employees´satisfaction rate (M&S)
In 2022, the survey was carried out for the first time only on hourly employees (and not on managers and salaried). For more information, see "Realizing our People´s Full Potential" chapter.
18. Health and Safety
