RESULTS 3rd Quarter and Nine 3Q18 RESULTS GRUPO MÉXICO Months 2018 Mexico City, October 24, 2018 Grupo Mexico, S.A.B. de C.V. (“Grupo Mexico” “GMexico” BMV: GMEXICOB). Consolidated sales accumulated in 2018 were 13% higher than in the same period of 2017, totaling US$7.92 billion. In the Mining Division, sales reached US$5.99 billion, during these months, higher metal prices were reported for copper (+10.3%), zinc (+8.7%), and Molybdenum prices (+48.5%). In the Transportation Division, cars hauled increased by 20% to 1.5 million while sales increased 19% vs. 9M17. In Infrastructure, total sales rose 7% compared to the first 9 months of 2017, reporting the start of sales of electric energy in the Wholesale Electricity Market (MEM for its Spanish acronym), better results in the operation of the Salamanca-Leon highway, and drilling platforms marine. Accrued copper production over the first 9 months of 2018 reached 733,895 tons, with greater production in the Mexican and Peruvian operations, which compensated for lower volumes from ASARCO, due to the landslide experienced at the Mission mine in the first quarter. In the Mining Division, we confirmed our first-place position as the Company with the lowest cash cost in the Industry, at US$1.09/lb. of copper, and the largest copper reserves worldwide. 9M18 EBITDA totaled US$3.73 billion, 17% greater than in the same period of 2017. The Mining Division reached US$2.75 billion, representing 15% growth vs. 2017. The Transportation Division achieved US$756 million in EBITDA, 18% above the figure for the first three quarters of the previous year. The Infrastructure Division's EBITDA reached US$200 million, 10% greater than in the same period of a year earlier. Net consolidated profit totaled US$1.07 billion in 9M18. 16% less than the previous year due to the impairment of treasury shares and changes in US tax policy Capital investments during 9M18 reached US$1.20 billion--17% growth compared to the first 9 months of the previous year, proving once again our commitment to growth and value generation. In the Mining Division, the Toquepala expansion was completed, which will generate a production of 20,000 tons of copper in 2018 and 100,000 tons per year as of 2019. In the Transportation Division, investments during 9M18 reached US$241 million, for the investments made for Celaya and Monterrey bypasses which will achieve greater operating efficiencies. Next year will mark another inflection point with extraordinary growth for our company, as we expect to achieve maximum capacity at our new Toquepala concentrator, and recover the production of the San Martin mine. Thereby, compared to our forecasts for 2018, we expect 2019 to show a 12% increase in copper production, +38% in zinc, +30% in silver, and +21% in molybdenum. At average prices of 3Q18, these production improvements would represent a sales increase of over US$800 million. On October 19, 2018, the Management Board declared the payment of a cash dividend of $0.80 pesos per share outstanding, to be made in a single installment as of November 23, 2018. This dividend implies an annualized dividend yield of 6.8%, reflecting the strong operating cash flow generation, given the completion of the first stage of investment with the fulfilment of the Buenavista in Sonora, México and Toquepala in Tacna, Perú.

Throughout the years, our financial discipline has enabled us to continuously invest in our large asset portfolio of projects. We operate metallurgical mining units with state-of-the-art technology in investment grade countries, such as Mexico, Peru, the US, and Spain. We are currently developing the next stage of growth to achieve a copper production capacity of 1.8 million tons by 2025. This represents an 80% growth against this year's production that we estimate is 1,003,000 tons of copper. Projects in Peru We continue to work on various projects in Peru, with a total capital investment of US$2.90 billion, US$1.70 billion of which has already been invested. Toquepala Expansion Project, Tacna.- This US$1.25 billion project includes a new, state-of-the-art copper concentrator that will expand annual copper production by 100,000 tons to total 258,000 tons of production in 2019, translating into a 74% increase. As of September 30, 2018, we had invested US$1.19 billion, and we have completed the expansion. We are in the operational testing phase with loading, while production will start in 4Q18. Tia Maria- Arequipa.- We have completed all the engineering and have complied with all environmental regulation, thus obtaining approval of the Environmental Impact Assessment. We are working together with the government of Peru to obtain the construction permit initiate operations in 2019 for this growth project worth 120,000 annual tons of SX/EW metallic copper that does not require combustion processes and that will use 100% of desalinated seawater with an investment of US$1.4 billion. The company expects the project to generate 3,600 new jobs during its construction phase. When in operation, Tia María will directly employ 600 works and 4,200 indirectly. We expect the license to be issued on December 2018. 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 80,000 tons of zinc and 20,000 additional tons of copper annually. To date, the basic engineering has been completed and we are working on the detailed engineering stage of the project. The budget for this investment is US$413 million, and it should be operational by 2020. Once the project is completed, the Mining Division’s zinc production will double. 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. To date, the engineering for the construction of the road between the Pilares pit and the La Caridad primary crushing plants has been completed, and work continues on the mining plan and the design of the Pilares pit. The investment budget is US$159 million, and it should begin operations in 2020. _____________________________________________________________________________________________________________________ 3Q18– 9M18 www.gmexico.com Page 2 WorldReginfo - 9bf2d452-4b92-4f51-adef-71e709f0d65e 3Q18 RESULTS GRUPO MÉXICO Projects in the US Asarco, Arizona.- The project to modernize the Hayden smelting facility in Arizona to comply 100% with the authorities’ new environmental regulation of Environmental Protection Agency, with an investment of US$229 million, has been completed. The smelting facility has state-of-the-art technology in its converter furnaces and the collection and management of gasses and dusts. This will result in greater efficiency and reach its new design capacity of 630,000 tons per year of copper concentrate smelting. At present, we are at the startup stage, achieving 80% capacity, and expect to reach 100% capacity during 4Q18. Mission, Arizona, USA.- On March 21, we suffered a landslide on the slopes of the Mission mine. To date, the corresponding authorities have authorized a return to normal operations. We expect production at the Mission mine to recover by 4Q18. Projects in Spain Aznalcóllar, Andalucía.- This project is located only 35 km from the city of Seville in Spain. During 2017, we carried out an intense exploration campaign whose results confirm the reserves and hint at a greater potential and appeal of the mineral ore than was originally estimated. Currently, we are in the process of obtaining the environmental and operating permits from the authorities. We are working on the feasibility studies, which we will complete by the end of the year; the detailed engineering will begin in the fourth quarter of 2018. The estimated investment for this project is US$290 million to begin operations in 2022, and it will enable Grupo’s annual production to grow by 105,000 tons of zinc equivalent. _____________________________________________________________________________________________________________________ 3Q18– 9M18 www.gmexico.com Page 3 WorldReginfo - 9bf2d452-4b92-4f51-adef-71e709f0d65e 3Q18 RESULTS GRUPO MÉXICO Relevant Events Transportation Division EBITDA Margin Expansion continues.- During 3Q18, GMXT’s EBITDA reached US$265 million—4% more than in 3Q17 with a 44% margin.
