Grupo Carso

Grupo Carso, formally Grupo Carso, S.A.B. de C.V., is a Mexican conglomerate associated with businessman Carlos Slim and the Slim family. The group was created in 1990 through the merger of Corporación Industrial Carso and Grupo Inbursa. Its name combines the first name of Carlos Slim with “Soumaya,” the first name of his wife, Soumaya Domit de Slim. The company operates through a diversified portfolio rather than a single consumer-facing product brand. Its principal activities include industrial manufacturing, commercial and retail businesses, infrastructure and construction, and energy-related operations. The group’s industrial activities are concentrated in Grupo Condumex, which produces and distributes a broad range of cable, electrical, electronic, automotive, steel-tube, transformer, and related products. Its commercial division is organized around Grupo Sanborns and includes department-store, restaurant, cosmetics, electronics, music, and specialty retail operations such as Sanborns, Sears Mexico, DAX, and iShopMixup. Grupo Carso’s infrastructure and construction activities are conducted through companies including CICSA and other specialized subsidiaries. These operations cover civil construction, roads, tunnels, water-treatment facilities, pipelines, telecommunications infrastructure, industrial and commercial buildings, housing, petroleum-related facilities, drilling, and other engineering work. The group also participates in energy and petroleum-related activities through Carso Energy, Carso Oil & Gas, and Carso Electric, including gas transportation services for Mexico’s Comisión Federal de Electricidad. The group has also had an important historical connection to telecommunications. In 1996, Carso Global Telecom, including the businesses associated with Telmex, Telcel, and América Móvil, separated from Grupo Carso. This separation distinguished the core conglomerate from the major telecommunications assets associated with the Slim business empire, while leaving Grupo Carso focused on its industrial, commercial, infrastructure, construction, and energy portfolio. As reported for 2023, commercial activities represented approximately 52 percent of Grupo Carso sales and 41 percent of operating income. Industrial and manufacturing represented approximately 31 percent of sales and 34 percent of operating income, while infrastructure and construction represented approximately 19 percent of both sales and operating income. These figures illustrate the group’s mixed operating model: commercial businesses provide a large share of revenue, while industrial and project-based operations contribute substantial earnings and strategic breadth. Grupo Carso also maintains research and development capabilities through CIDEC, the Centro de Investigación y Desarrollo CARSO, in Querétaro. Its work includes prototypes, pilot plants, electrical and electronic systems, and embedded software for automotive applications. The group’s geographic identity remains strongly Mexican, although its operations and commercial relationships extend into Latin America and Spain. It is listed in Mexico under the ticker GCARSO A1.

Grupo Carso was established in 1980 as part of Carlos Slim Helú's expansion from investment and financial activities into a broad operating conglomerate. The name Carso is derived from Carlos Slim and Soumaya Domit. From its early years, the group followed an acquisition-led and diversification-oriented model, building positions in businesses that could benefit from Mexico's industrialization, infrastructure requirements, and expanding consumer economy. A major stage in the group's development was the consolidation of industrial companies associated with Condumex. These businesses provided cables, conductors, electrical products, automotive components, and other manufactured goods. The industrial platform gave Grupo Carso technical capabilities and a base of Mexican manufacturing operations, while also supporting participation in telecommunications, power, transportation, and construction supply chains. The group subsequently expanded its construction and infrastructure presence. Carso Infraestructura y Construcción, or CICSA, became a central vehicle for civil works, industrial facilities, telecommunications infrastructure, pipelines, and energy-related construction. Through CICSA and affiliated companies, Grupo Carso has participated in public and private infrastructure projects in Mexico and selected international markets. The construction business has been important both as a source of direct revenue and as a way to connect the group's industrial and energy capabilities with large project opportunities. Energy became another significant area of activity. Carso Energy has been used for investments and operations involving hydrocarbons, pipelines, power generation, and related infrastructure. The group's energy interests have included participation in projects and concessions connected with Mexico's changing energy framework. As with other conglomerates, individual assets and contracts have moved between subsidiaries or changed ownership over time, so historical descriptions do not necessarily define the group's current portfolio. Grupo Carso also developed a substantial consumer and retail presence. Grupo Sanborns brought together department-store, specialty-retail, restaurant, and café operations, including the Sanborns and Sears México businesses. These activities diversified the group away from industrial and project-based operations and gave it recognizable consumer-facing brands. The retail portfolio has undergone periodic corporate changes, including the separation or reorganization of listed and unlisted entities within the wider Slim group. The company became a public issuer on the Mexican Stock Exchange. Its listed structure provides a public-market vehicle for a diversified portfolio while leaving strategic control associated with the Slim family and affiliated interests. Grupo Carso's governance and capital allocation have therefore been shaped by both the requirements of a public company and the long-term investment approach characteristic of the Slim business network. During the 2010s and 2020s, Grupo Carso continued to pursue infrastructure, construction, energy, industrial, and real-estate opportunities. It remained connected to major Mexican development projects and to the country's telecommunications and energy infrastructure. The group has also faced the ordinary regulatory, execution, concession, and public-policy risks associated with large infrastructure and energy projects. Its corporate identity today is best understood not as a single operating brand but as a diversified Mexican holding and operating group whose subsidiaries serve different industries and customer types.
