Fourth Quarter and 2020 Annual RESULTS

Mexico City, January 26th, 2021

Grupo México, S.A.B. de C.V. (“Grupo México” “GMéxico” - BMV: GMEXICOB)

Just as w e have been doing since the beginning of the pandemic, Grupo M éxico will continue to operate its Three Divisions with the corresponding measures to safeguard its employees’ health, by applying safe distance measures, using facemasks, and following all the health standards set in place by the local authorities of the countries in which we operate. Grupo Mexico’s industrial activities generate minimum risks as most of them are performed outdoors, and by one person or by a small number of highly qualified collaborators.

Accrued revenues during 2020 totaled US$10.91 billion—a record figure in Grupo México’s history—2.1% higher than in 2019 and 22.1% higher in 4Q20 compared to 4Q19. The Mining Division’s revenues totaled US$8.57 billion in 2020, 7.5% higher than in 2019, and 35.5% higher in 4Q20 vs 4Q19, due to higher volumes produced—Copper (+1%), Molybdenum (+12.5%), and Silver (+10%)— in addition to a favorable environment in the prices of Copper (+2.9%), Silver (+27.6%), and Gold (+27.1%), In the Transportation Division, revenues dropped 12.7% during 2020, totaling US$2.15 billion due to reduced volumes caused by the pandemic. The Infrastructure Division achieved accrued net revenues of US$528 million—a 9.0% decrease in the year due to an adjustment in the daily rates in PEMSA and the effects on Construction and Highways that resulted from the health contingency. The Transportation and Infrastructure Divisions showed recoveries in revenues of 0.7% and 3.2% respectively when comparing 4Q20 to 3Q20.

2020 was a record year in copper, molybdenum, and silver production. Thanks to the timely implementation of the COVID-19 protocol, the strict hygiene and safety measures that we implemented in all our operations since the onset of the pandemic, w e achieved a new production record in copper, totaling 1,128,927 tons, 1% higher than in 2019 and 2.4% higher during 4Q20. This was mainly due to the production in the mines of Peru (+2.3%) as a result of higher ore grades and the recovery in Cuajone, as well as greater production at our US mines (+1.7%). Molybdenum production increased by 12.5% and silver grew 10.3%.

In the Mining Division, due to our cost and efficiency policy, we managed to reduce global net cash cost from US$1.07 to US$0.85, -20.5% vs. 3Q19 and -24.2% vs. 4Q19. Thus, we reiterate the best cost in the copper industry w orldwide, and our capacity to maintain efficiencies despite the adverse scenario. Moreover, we remain ranked in first place worldwide in copper reserves.

As a result of investing over US$18 billion in the last 10 years, we achieved record EBITDA of US$5.35 billion during 2020, 8.2% higher year over year, and 48.5% higher than the same period last year. The Mining Division reached US$4.15 billion in EBITDA, 16.5% more than in 2019 and 76.7% higher in 4Q20—also a record for the Division. The Transportation Division’s EBITDA totaled US$944 million in 2020, decreasing 13.9% given the loss of revenues mentioned above. The Infrastructure Division’s EBITDA totaled US$267 million in 2020—2.0% less compared to 2019. However, it shows a 4.2% increase when comparing 4Q20 to 3Q20, which reveals a recovery trend.

Net consolidated profit for 2020 reached US$2.10 billion, showing a 19.3% increase vs. the previous year and 96.5% vs. 4Q19.

QUARTERLY AND ANNUAL 2020 RESULTS

Capital investments totaled US$1.113 billion in 2020. Investments in growth projects have been smaller than expected as a result of the COVID-19 pandemic, given the slowdown in construction, and that we have reduced the mobility of external personnel and contractors in our operations to protect our workers . During 2021, we expect to invest US$2.153 billion in different projects across the Three Divisions that will be the source of economic r eactivation and employment generation as the pandemic allows us.

Dividend. - On January 22, 2021, the Management Board declared the payment of a cash dividend of P$1.25 per share outstanding, to be made in a single installment as of February 26, 2021. This dividend implies an annualized dividend yield of 5.54%.

Relevant Events Grupo México

Grupo México is the third largest company in the country in terms of market cap and the fourth in marketability. It is the second company in tax payments and the first one in EPS in Mexico and Peru. It has generated over 29,400 direct jobs in 2020, and over 29,000 indirect ones, with high training and good pay. Grupo Mexico is the fifth copper producer worldwide, with the lowest cash-cost in the global industry.

Gr upo México in the last decade.- In the last 10 years, we have increased our revenues by 31%, we have managed to improve our EBITDA by 37%, and we have increased our margin by 208 basis points. We have invested over US$18 billion, which have driven the economic development of the communities where we operate.

Current CO VID-19 Situation.- In 2020, Grupo Mexico faced the challenge of the pandemic with resilience, innovation capacity, and a solidarity approach. The new normal that the virus has imposed on the world requires a sense of shared responsibility among governments, companies, and society, for everyone’s protection and to afford continuity for growth and value generation, and thus to contribute to the economic recovery.

As of the first signs of the COVID-19 pandemic, early in 2020, Grupo Mexico endorsed its commitment, first and foremost, to protect the health of its workers, their families, and the communities and regions in the countries where it operates. Since the first stage of the health contingency, the company defined as its main lines of action to guarantee safe work environments and to contribute to the prevention of the illness, as well as help to strengthen the social and hospital response capacity.

In addition to the necessary investments made by Grupo Mexico in the facilities to protect its workers, Fundación Gr upo México allocated an extraordinary budget of 500 million pesos, to protect healthcare personnel and support COVID hospitals’ capacity to provide medical care nationwide. These investments include preemptive care units to promote healthcare, food supplies, and medicine for those workers in need, along with facilities to quarantine away from home stopping the spread of the virus to their relatives.

Likewise, we donated nearly half a million kits of personal protection gear for healthcare professionals; we delivered 139 respiratory support fans and 500 non-invasive ventilators to hospitals across various states of the Republic, as well as a significant quantity of medical materials, such as monitors, beds, and CPR carts.

In March, Grupo México announced the anticipated delivery of a hospital in Juchitan, in the state of Oaxaca, which was habilitated by the Mexican Army for the care of COVID-19 patients. Likewise, the team of medical professionals who participate in Doctor Vagón (Dr. Wagon), the Health Train, was assigned by Fundación Grupo México to support patients in the Cananea General Hospital.

Hundreds of portable handwashing units were installed to benefit the communities, and in Sonora, company facilities were adapted with dozens of beds available for the care of COVID-19 patients with mild to moderate cases of the illness, and a 24-hour hotline was activated to answer the population’s questions and concerns regarding the contingency.

In Peru, 18 temporary hospitals were donated with capacity for 250 beds, including the corresponding supply of oxygen for each of them. Moreover, to contribute to guarantee the supply of oxygen in the country, in regions of

QUARTERLY AND ANNUAL 2020 RESULTS

Arequipa and Moquegua, 318 thousand liters of liquid oxygen w ere supplied to national hospitals; meanwhile, in Tacna and Puno, tw o oxygen plants were donated, with daily capacities of 720m3 and 222m3, respectively.

To favor the timely detection of cases and slow the chain of transmission of COVID-19, a PCR test lab was donated in the Moquegua region. In addition, personal pr otection gear has been delivered to healthcare professionals.

Both in Mexico and Peru, we have assisted the most vulnerable population through the distribution of thousands of food baskets and through the community development programs that the company permanently operates.

All of Grupo México’s operations maintain—rigorously and updated continuously—health safety protocols focused on risk prevention and containment, to ensure that all the company’s employees can carry out their job in safe environments.

The application of serologic or PCR tests is already a standard operating procedure, at the start of each shift, and it is now a fundamental instrument to prevent infections and protect thousands of employees in the Group’s Three Divisions.

Given the efficacy of the measures and prevention protocols, towards yearend, the company’s mining operations were awarded the Health Safety Badge by the Mexican Social Security Institute.

Showing solidarity and contributing to protect the communities where we are present is a priority for Grupo México in face of the pandemic. In all of them, we have implemented intensive communication campaigns regarding the measures for prevention and hygiene recommended by the health authorities in view of the COVID-19 infections.

Projects

Throughout the years, we have proven that the Group’s investment philosophy is not based on copper price outlooks, but on the quality and efficiency of the assets that we operate and develop. We continue to focus on being the cost leaders in the global industry, and on operating with the efficiency and financial discipline that is our hallmark.

Projects in Mexico

Considering the projects, we will develop in the medium to long term at El Arco and Empalme, as well as the ongoing ones, explained below:

Buenavista Zinc, Sonora. - This project is located within the Buenavista deposit in Sonora and comprises the construction of a concentrator with a production capacity of 80,000 tons of zinc and 20,000 additional tons of copper annually. To date, the basic engineering has been completed, and the detailed engineering is now underway. Preparation of the deposit has begun, and greater preventive measures against COVID-19 have been implemented. Moreover, purchase orders for machinery and equipment have already been placed, and the project has all the necessary permits. The budget for this investment is US$413 million, and it should be operational by 3Q22. Once this new concentrator is completed, our zinc production capacity will double, and 490 direct jobs and 1,470 indirect ones will be created.

Pilares, Sonora. - This project is located in Sonora, 6 km away from the La Caridad mine, and it has an open-pit mine, with an annual production capacity of 35,000 tons of copper concentrates. The construction of the 25-m- wide road for mining trucks to transport the ore between the Pilares pit and the primary crushing plants in La Caridad has begun. This project will significantly improve the total ore grade (combining the expected 0.78% from Los Pilares with La Caridad’s 0.34%). The investment budget is US$159 million, and operations should begin in the first half of 2022.

El Pilar, Sonora. - This new low capital-intensive copper project is strategically located in Sonora, Mexico, roughly 45 km away from our Buenavista mine. Its copper oxide mineralization has proven, and probable reserves estimated at 325 million tons of ore, with a copper ore grade of 0.287%. El Pilar will function as a conventional open pit mine, and copper cathodes will be produced using the highly cost-efficient and environmentally friendly SX/EW technology. The budget for El Pilar is US$310 million, and we expect it to begin production during 2023. The results achieved on the pads in the leaching process confirm that there are suitable copper recovery levels.

El Arco. - This world-class copper deposit located in the center of the Baja California peninsula has ore reserves of over 2.4 billion tons with an ore grade of 0.426%; 0.3 billion tons of leachable material with an ore grade of 0.288%; and 0.11 grams of gold per ton. This project includes an open-pit mine with concentrator operations and a leaching plant. We expect annual production to settle around 190,000 tons and 105,000 ounces of gold, with a capital investment of US$2.90 billion. We have already begun the preliminary studies and are reviewing the basic engineering plan to request the environmental impact permit. We have started studies as well as basic engineering

to request the environmental impact manifestation. We have had the corresponding mining concessions for several years now, and during 2020 we finished acquiring all the land needed.

Projects in Peru

We continue to work on various projects in Peru under our capital investment program. We have an approved investment program of US$2.80 billion, of which we have invested over US$1.6 billion. Considering the new Michiquillay (US$2.50 billion) and Los Chancas (US$2.60 billion) projects, our total investment program in Peru amounts to US$7.90 billion.

Tía María - Arequipa. - We have worked constantly on promoting the wellbeing of the population in the Islay province. As part of these efforts, we have implemented successful social programs for education, healthcare, and productive development to improve people’s quality of life, encouraging farming and livestock activities in the Tambo valley, as well as the growth of manufacturing, fishing, and tourism in Islay.

We reiterate that the start of construction activities for Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region. Given the current economic situation, it is essential to continue projects that will stimulate a sustainable growth cycle. During the construction and operation phase, our priority will be the engagement of local labor to cover the 9,000 jobs (3,600 direct and 5,400 indirect) that we expect to generate. Once operations begin, we expect Tia Maria to employ 600 workers directly and to provide 4,200 indirect positions as well. Moreover, since the start of operations, we will generate significant contributions to the revenues of the Arequipa region through royalties and taxes.

We expect the Peruvian government to acknowledge the significant progress the project has made in the social environment and the important contributions that Tia Maria will make to the Peruvian economy, and thus, take the necessary steps to begin construction.

Projects in the US

ASARCO, Arizona. - Despite the stoppage by the unions in the Arizona operations, Asarco achieved a production of 127,558 tons of copper in 2020, 1.7% above 2019, with a cost per lb. of US$1.99 after byproducts, -20.1% vs 2019. This cost has been the lowest we have obtained in the last 4 years.

Relevant Events Transportation Division

In the Tr ansportation Division, net revenues accrued in 2020 totaled US$2.15 billion and EBITDA, US$944 million— 12.7% and 13.9% decreases vs. 2019, respectively, due to a reduction in cargo in some of our segments, and to more than US$23.5 million in donations and non-recurrent costs incurred to implement protocols and aid given the situation that the world is facing because of the pandemic caused by the COVID-19 virus. In 4Q20, revenues totaled US$541 million—13.7% below 4Q19. 4Q20 EBITDA totaled US$234 million—15.9% lower than in 4Q19. This is mainly due to approximately US$10 million decrease in revenues from freight that reflects directly in EBITDA and a non-recurring increase in sales of US$11 million during the 4Q19.

Volumes transported.- During 4Q20, volumes declined 3.2% in tons-km, and 4.1% in carloads, impacted by the reduction in cargo mainly in the Agriculture and Industrial segments, which reported decreases of 11% and 7%, respectively, in tons-km.

Gr owth of the Chemicals and Fertilizers Segment.- Accrued up to the fourth quarter, the segment shows increases of 10% in revenues, 4% in tons-km, and 1% in carloads, as the COVID-19 pandemic benefited the demand of some chemical industries, we gained market share in fertilizers, and new routes were opened. Gr owth of the Energy Segment.- The segment showed accrued growth of 3% in revenues and 0.4% in tons -km up to the fourth quarter, as a result of increases in imports from new clients and longer routes, which countered the drop in demand due to COVID-19. Gr owth of the Agriculture Segment.- The segment showed accrued growth in the fourth quarter of 2% in revenues, due to higher carousel imports and a larger market share of local crops and ports. Growth of the Minerals Segment.- The segment shows an accrued variation of 1% in revenues, 0.2% in tons -km, and 0.2% in carloads, due to an increase in market share, achieved through operating efficiencies.

Important Productivity Improvements. – During 2020, all our Efficiency indicators achieved significant improvements, due to the implementation of different actions to optimize our Service Master Plan, which has enabled us to improve our service quality and the use of our assets.

During 4Q20, the average train length increased 5.1% vs. 4Q19, totaling 1,974 meters. The gross tons per train increased by 4.5% totaling 6,329 tons per train. This enables us to transport a greater load with fewer trains, thus saving on crews and freeing up railway capacity to continue to improve speed. As a result of the above, crew starts decreased a significant -6.9% during the quarter.

We managed to reduce dw ell time by 30.1%, totaling 23.92 hours, and average train speed remained at 38.10 km/hr, similar to 4Q19.

During 2021, we will focus on continuing with the implementation of our efficiency program to get these indicators to keep improving.

Relevant Events Infrastructure Division

Infrastructure Division.- During 2020, revenues accrued US$528 million and EBITDA US$267 million, which was only 2.0% lower vs. the same period of 2019, due to the adjustment in Drilling installments and the effects on the Highways and Construction segments as a result of the health contingency. However, EBITDA to sales margin increased 4%, settling at 50.7%, due to the good results in Energy and Engineering.

Energy Generation.- By the end of 4Q20, revenues accrued US$230 million, translating into a 1.9% increase vs. 2019, mainly as a result of the increase in the price of gas molecule. Generation has totaled 3,656 MWh vs. 3,626 MWh in the same period a year earlier—a 1.0% increase. EBITDA margin settled at 52.8%, accruing a total of US$122 million in 4Q20— a 3.7% increase vs. 2019.

New Fenicias Wind Farm.- This 168MW renewable project, located in the state of Nuevo Leon, shows 83.0% progress. Construction on the 60KM transmission line was completed; the construction works on the booster substation, roads, and digs are about to be completed, and the installation of the wind turbines is still underway. This wind farm will provide electric energy to our IMMSA mining and metallurgic operations. To date, we have invested US$177 million, translating into 71.0% of the project’s total cost. It is expected to start operations towards the end of the first quarter of 2021.

O il Division (PEMSA).- 4Q20 ended with our 6 rigs in operation and an average efficiency of 99.5%—the highest in PEMSA’s history. The revenues accrued up to the end of 4Q20 totaled US$172 million and EBITDA settled at US$85 million, translating into decreases of 1.3% and 3.8%, respectively vs. 2019. This decrease was mainly a result of adjustments in installments, scheduled maintenance on the Tabasco and Campeche rigs, and extraordinary expenses related to COVID- 19.

M éxico Compañía Constructora.- By the end of 4Q20, revenues accrued US$77 million and EBITDA US$23 million, translating into decreases of 37.8% and 8.7%, respectively, vs. 2019. The decrease in EBITDA compared to the previous year is the result of lower accrued production, the suspension of construction activities due to the health contingency, and the completion of certain projects.

Engineering Services.- By the end of 4Q20, revenues accrued US$25 million and EBITDA US$8 million, translating into record figures and increases of 40.0% and 127.0%, respectively, vs. the same period a year ago. This good performance is due to a larger number of projects contracted with different clients in various industries.

Highway Division.- During 2020, revenues accrued by the end of 4Q20 totaled US$34 million and EBITDA totaled US$23 million, both decreasing 20.7% vs. the same period a year earlier, but the EBITDA to sales margin remained at 64.0%. Equivalent monthly traffic totaled 9,555, 23.0% lower compared to 2019. This decrease was a result of mobility restrictions due to the COVID-19 pandemic.

Fuel bunkering and storage.- The Cadereyta Bunkering terminal’s operations accrued revenues of US$2 million and EBITDA of US$1 million by the end of 4Q20. The new fuel storage projects in Monterrey and Guadalajara are still underway, with estimated startup dates set for 2Q22 and 4Q22, respectively, as well as the project for a new bunkering terminal in Aguascalientes, with a startup date set for 2Q22.
