First Quarter 2021 RESULTS

Mexico City, April 27, 2021

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

As we have maintained the strictest protocols against COVID-19 throughout the pandemic, during the first quarter, we achieved excellent financial and operating results in the Group. We kept production levels in the Mining Division above the guidance provided at the end of 2020, and showed volume growth in the Transportation Division, even though the 2020 comparison base does not include the effects of COVID-19.

First quarter 2021 revenues reached a record US$3.43 billion, 40.2% higher than in 1Q20, and 6.8% higher than in 4Q20. The Mining Division achieved record sales of US$2.80 billion in 1Q21, 56.1% higher than in 1Q20, as copper sales increased by 2.4% and we kept the volumes produced in line with the previous year, as well as increases in the prices of copper (+50.2% Comex), Molybdenum (+17.0%), Zinc (+28.9), Silver (+55.8%), and Gold (+13.6%). In the Transportation Division, sales fell 2.1% during 1Q21 totaling US$593 million, mainly because of an impact due to the exchange rate, as volumes grew 2.3% and sales in pesos had a slight increase. Sales rose 9.6% against 4Q20. The Infrastructure Division achieved accrued net revenues of US$148 million, an 8.3% increase during 1Q21, and 8.4% higher than in the previous quarter.

Due to the strict protocol, we have implemented in health and safety in the face of the COVID-19 pandemic and despite the very complicated environment, we managed to keep copper production practically in line, totaling 271,312 tons, 0.5% below 1Q20, because of a 3% decrease in production in Peru's operations due to lower ore grades, which was partially mitigated by increases in IMMSA (+9.5%) and in ASARCO operations (+7.3%).

In the Mining Division, we achieved a reduction in net operating cash cost globally from US$0.93 to US$0.88, due to higher prices of other metals. Thus, we reiterate the best cost in the copper industry worldwide, and our capacity to maintain efficiencies despite restrictions imposed due to the COVID-19 pandemic. Moreover, we remain ranked in first place worldwide in copper reserves.

As a result of an intensive investment program of more than US$18 billion and an operating scheme that maximizes efficiencies, as well as the work enabled by thousands of specialized collaborators at our mines, we succeeded in increasing copper production from 688 thousand to 1.13 million tons in the last 10 years. This cycle of high metal prices enabled us to materialize this, generating a record EBITDA of US$2.13 billion in 1Q21, 99.7% higher than in the same quarter of last year and 23.3% above 4Q20. The Mining Division reached US$1.8 billion in EBITDA, 158.4% higher than in 1Q21 and 26.4% higher than in 4Q20. The Transportation Division obtained an EBITDA of US$264 million during the quarter, with a 6% decrease, but showing a 12.8% recovery against 4Q20. In the Infrastructure Division, EBITDA was US$60 million during 1Q21, US$20 million lower compared to 1Q20 and 5.9% lower than in 4Q20. This is mainly due to a foreign exchange loss in peso-denominated debt and lower platform fees.

Consolidated net profit for 1Q21 totaled US$1.03 billion, also a result of our extensive capital investment plan of previous years.

Capital investments during 1Q21 were US$337 million, +39.5% due to additional progress in growth projects. Our 2021 capex program is a US$2.1 billion plan in different projects across the Three Divisions that will be the source of economic reactivation and employment generation insofar as the pandemic allows. gmexico.mx

FIRST QUARTER 2021 RESULTS

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 first company in tax payments and the first one in profit sharing in Mexico and Peru. It has generated over 29,400 direct jobs in 2020, and over 110,000 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, and it has the largest copper reserves in the world.

Current COVID-19 Situation.- Under the premise that joint accountability between governments, companies, and society is essential for the protection of all and to ensure economic growth and social development, Grupo México has collaborated in solidarity with the efforts of authorities in Mexico and Peru, especially with the vaccination logistics in communities where the company is present.

We believe that the efforts made by the Government of Sonora (Mexico) to implement the vaccine are a key positive event for our operations. Through this vaccination plan, 100% of the medical staff of our operations have already been vaccinated. In addition, 98% of our staff over the age of 60 in Cananea and 100% in Nacozari have been vaccinated, too. This significant progress protects our staff from becoming infected with COVID-19 and allows them to have peace of mind for themselves and their families. It also allows the company to start operating normally at its facilities. The company is contributing to the vaccination plan by providing logistics support.

The donation of medical supplies in Mexico and Peru, amounting to US$2.2 million, has been continued, emphasizing regions where COVID-19 infections have increased, including areas where the company does not have an operational presence, but where the health situation has warranted it. In the case of Peru, given the increased demand for medical-grade oxygen, Fundación Grupo México and the Ilo Smelter signed a contract for the donation of 2 thousand 500 tons of liquid oxygen.

Moreover, the Community Development model continues to strengthen its virtual offer of cultural, sporting, and recreational workshops for the general population. In the first quarter of the year, 1,095 new workshops of the more than 5 thousand held since the beginning of the pandemic were added, while the eleven schools sponsored by the company serve 3,756 students online in Mexico and Peru.

All Grupo México’s operations continue to apply rigorous health security protocols aimed at preventing infection and generating safe environments for work. Testing is still a routine operating procedure.

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

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 100,000 tons of zinc and 20,000 additional tons of copper annually. The basic engineering has already been completed, and detailed engineering is about to be completed, with 89% progress. Further preventive measures against COVID-19 have been implemented to continue with the project. Moreover, purchase orders for machinery and equipment have already been placed, and some of these are already in the process of being produced. As part of this process, the mill manufacturing process has already been completed and its respective components are being shipped. The project already has all the necessary permits. The budget for this investment is US$413 million, and it should be operational by 2023. 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. - Located 6 kilometers away from the La Caridad mine, this project consists of an open-pit mine, with an annual production capacity of 35,000 tons of copper concentrates. A new 25-meter wide off-road facility for mining trucks has been built and will be used to transport the ore from the pit to the primary crushers at the La Caridad copper concentrator. 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 quarter of 2022.

El Pilar, Sonora. - This new low capital-intensive copper greenfield 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 281 million tons of ore, with a copper ore grade of 0.301%. El Pilar is expected to function as a conventional open pit mine with an annual production capacity of 36,000 tons of copper cathodes. This operation will use highly cost efficient and environmentally friendly SX-EW technology. The budget for El Pilar is US$310 million and we expect production to begin during 2023 with a mine life of 13 years. The results achieved on the pads in the leaching process confirm that there are suitable copper recovery levels. The basic engineering has already begun.

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 0.422%; 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 of copper and 105,000 ounces of gold, with a capital investment of US$2.90 billion. We have already started the studies, as well as the basic

engineering to request the environmental impact assessment. For years, we have had the corresponding mining concessions, and during 2020, we concluded the acquisition of all the necessary land.

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 (U$2.50 billion) and Los Chancas (U$2.60 billion) projects, our total investment program in Peru amounts to U$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.

On January 7, the mayor of the largest province of Islay (Arequipa, Peru) acknowledged Southern Copper with an award called the City Diploma due to the efforts to assist the population of Islay during the COVID-19 pandemic. Southern Copper provided medical assistance, testing, oxygen, personal protective equipment, and food products to the population in the area of influence of the Tia Maria project.

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. – as a result of the extensive operation analysis that we carried out last year, Asarco achieved production of 32,909 tons of copper during 1Q21, 7.3% above 1Q21 and 9.0% higher than in 4Q20, with a cost per pound of US$1.82 after byproducts, 8.8% less than in 1Q20 and 11.7% lower than in 4Q20.

FIRST QUARTER 2021 RESULTS

Relevant Events Transportation Division

In the Transportation Division, net revenues for 1Q21 totaled US$593 million and EBITDA, US$264 million —2.1% and 6.0% decreases, respectively. Mainly because of an impact due to the exchange rate, as sales in pesos had a slight increase and volume grew during the quarter. Volumes continue a recovery trend, with a 3.3% increase in tons-km and 3.7% in carloads vs. 4Q20, and growth in market share and demand in the construction industry in Florida.

Volumes transported. - During 1Q21, volumes grew 2.3% in tons-km, mainly in the Energy, Metals, and Agriculture segments, with tons-km increases of 12, 9, and 5%, respectively.

Growth of the Energy Segment. - The segment showed growth in the first quarter with 11% in revenues and 12% in tons-km as a result of an increase in imports of refined products and LP gas, as well as the reactivation of fuel oil exports.

Growth of the Minerals Segment. - The segment shows an accrued variation of 6% in revenues, 0.5% in tons-km, and 6% in carloads, due to an increase in market share in the United States and the stabilization of domestic iron ore production.

Growth of the Metals Segment. - The segment has accrued increases of 7% in revenues, 9% in tons-km, and 6% in carloads, mainly due to the increase in both import and domestic traffic of scrap, rods, and steel slab.

Growth of the Agriculture Segment. - The segment showed growth of 1% in revenues and 5% in tons-km in the first quarter as a result of an increase in carousel train imports impacted by unfavorable exchange rate variations during March.

Important Productivity Improvements. – During the first quarter of 2021, our main 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 1Q21, the average train length increased 6.5% vs. 1Q20, totaling 1,957 meters. The gross tons per train increased by 10.2% totaling 6,421 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 -7.7% during the quarter.

Train speed remained at levels of 38.0 km/hr, similar to 1Q20, which allows us to be consistent with the planning of our resources and service.

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

FIRST QUARTER 2021 RESULTS

Relevant Events Infrastructure Division

Infrastructure Division.- During the first quarter of 2021, sales accrued US$148 million, 8.3% more than in the previous year, and EBITDA totaled US$60 million, which was 25.5% lower compared to the same period in 2020, mainly due to an exchange rate effect. Other points that affected the division’s EBITDA were the adjustment of rates in Pemsa, lower sales from the El Retiro wind farm, and the effects on Highways as a result of the health contingency.

Energy Generation.- At the end of 1Q21, sales accrued US$81 million, translating into an increase of 46.6% vs. 2020, mainly because of the rise in the price of the gas molecule, following the polar vortex witnessed during February in the Permian basin. EBITDA margin settled at 33.9%, accruing a total of US$28 million in 1Q21—a 22.8% decrease vs. 2020, mainly due to lower Exchange rate gains on liabilities in pesos at El Retiro, and lower energy volumes sold at this Wind Farm.

New Fenicias Wind Farm.- This 168MW renewable project, located in the state of Nuevo Leon, has 94.0% progress (100% engineering, 100% in procurement, and 91% under construction). The 60 Km transmission line, the booster substation, roads, and excavations were completed; and the assembly of wind turbines is about to be completed (we already have 18 operational wind turbines out of a total of 42). This wind farm will provide electric energy to our IMMSA mining and metallurgic operations. To date, we have invested US$206 million, translating into 82% of the project’s total cost. On March 16, 2021, the park was energized, allowing the start of the testing period and power delivery to the grid.

Perforadora México (PEMSA).- 1Q21 ended with our 6 rigs in operation and an average efficiency of 99.8%—the highest in PEMSA’s history. The revenues accrued up to the end of 1Q21 totaled US$38 million and EBITDA settled at US$18 million, translating into decreases of 21.8% and 26.2%, respectively, vs. 2020. This decrease was mainly a result of adjustments in quotas with Pemex to ensure operations and avoid suspensions.

México Compañía Constructora.- By the end of 1Q21, revenues accrued US$17 million and EBITDA US$4 million, translating into variations of -2.5% and +7.2%, respectively, vs. 2020. The drop in income is due to the completion of works (Juchitán Hospital, Celaya bypass, among others), and the growth in EBITDA compared to the previous year is the result of an improvement in our costs, as well as recognition of other revenue from the sale of fixed assets and surplus material.

Engineering Services.- By the end of 1Q21, revenues accrued US$6 million and EBITDA US$1.2 million, translating into decreases of 7% and 57%, respectively vs. the same period of a year ago. The decrease in EBITDA was caused by lower exchange rate gains and adjustments in the rates of some projects to ensure production.

Highway Division.- During 1Q21, revenues accrued US$9 million and EBITDA US$6 million, decreasing 9.9% and 20%, respectively vs. the same period of the previous year. A daily equivalent traffic of 15,894 units was reported—9% less compared to 2020. This decrease was mainly due to mobility restrictions from the COVID-19 pandemic.

Fuel Transload and Storage Terminals.- The Cadereyta Transload terminal’s operations accrued revenues of US$608 thousand and EBITDA of US$221 thousand by the end of 1Q21. The new fuel storage terminals in Monterrey and Guadalajara are still underway, with estimated startup dates set for 4Q22 and 2Q23, respectively, as well as the project for a new bunkering terminal in Aguascalientes, with a startup date set for 4Q22.
