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. gmexico.mx 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.

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.

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.
