Carlos Slim Helú, a Mexican business magnate, investor, and philanthropist, has made a significant impact on the business world. From being ranked as the richest person in the world to his extensive holdings in various industries, Slim’s success story is remarkable. This article delves into Slim’s business career, highlighting his early life, his conglomerate Grupo Carso, and his expansion into the global market.

Early Life And Business Lessons

Slim was born on January 28, 1940, in Mexico City, to Lebanese parents. From a young age, he showed an interest in business and received valuable lessons from his father, focusing on financial management and accounting techniques. Slim’s understanding of financial statements and the importance of accurate record-keeping laid the foundation for his future success.

Building A Business Empire

After graduating from university in 1961, Slim began his business career as a stock trader in Mexico. Working long hours, he quickly made a name for himself in the Mexican business world. In 1965, Slim established Inversora Bursátil, a stock brokerage house, and laid the groundwork for his conglomerate, Grupo Carso. He also acquired Jarritos del Sur, a Mexican bottling and soft drink company, and established Inmuebles Carso, a real estate agency and holding company.

Diversifying Business Operations

Throughout the 1970s, Slim expanded his business operations across various industries in Mexico. He ventured into construction, soft drinks, printing, real estate, bottling, and mining, among others. Slim’s strategy involved buying businesses and retaining them for their cash flow or selling them at a higher profit in the future. This approach, combined with Grupo Carso’s conglomerate structure, made his business nearly recession-proof.

Expanding Into Global Markets

In the 1990s, Slim’s business empire expanded beyond Latin America and into the global market. One of his significant achievements was acquiring Telmex, the landline telephone operator, from the Mexican government during the privatization of Mexico’s telecom industry. Telmex, along with his wireless telecommunications company Telcel, formed the backbone of his private fortune. By 2006, Telmex controlled 90% of Mexico’s telephone lines and Telcel operated 80% of the country’s cellphones.

Entering The United States Market

In the late 1990s, Slim set his sights on the United States as a destination for potential foreign investment acquisitions and business opportunities. While the majority of his business holdings remained in Mexico, he recognized the potential for growth and success in the US market. This expansion marked a significant milestone in Slim’s career, as he sought to diversify his portfolio and establish a presence on a global scale.

Expansion Into US Retail Market

In the early 2000s, Slim made headlines by purchasing significant stakes in several major US retailers. This move included acquiring shares in Barnes & Noble, OfficeMax, Office Depot, Circuit City, Borders, and CompUSA. Slim’s international expansion beyond Mexico was driven by the belief that there were limited acquisition opportunities left in Mexico. This foray into the US retail market demonstrated Slim’s strategic vision and willingness to diversify his portfolio.

Investments In Telecommunications

Slim’s telecommunications empire, América Móvil, continued to expand during this period. In 2000, América Móvil was incorporated as the holding company for Telmex, which spun off its international cellular phone division. América Móvil went on to acquire stakes in various international cellular phone operators outside of Mexico, including ATL and Telecom Americas in Brazil, Techtel in Argentina, and others in Guatemala and Ecuador. This expansion allowed Slim to establish a significant presence in Latin America’s telecommunications market.

Venturing Into Other Industries

Slim’s business interests extended beyond telecommunications. In 2005, he invested in Volaris, a Mexican airline, demonstrating his willingness to diversify his holdings. Additionally, Slim established Impulsora del Desarrollo y el Empleo en América Latina (IDEAL), a construction and civil engineering company primarily engaged in not-for-profit infrastructure development. IDEAL won several infrastructure contracts, although it faced competition from other Mexican and Spanish construction companies.

Broadcasting And Media Ventures

Slim also made notable investments in broadcasting and media during the 2010s. In 2012, he sold the broadcast rights for Leon soccer games to Telemundo, Fox Sports, and the website Slim’s involvement in broadcasting extended beyond Mexico, as his company América Móvil acquired the broadcast rights for the Olympic Games in Sochi 2014 and Brazil 2016 for Latin America. He also co-founded Ora TV, an on-demand digital television network, with Larry King, producing and distributing television shows.

Sports Investments

Slim’s interest in sports extended to ownership stakes in Mexican soccer teams. In 2012, through América Móvil, he acquired 30% stakes in Pachuca and León. He also purchased all the shares of Estudiantes Tecos, a second division team. Slim’s involvement in sports extended to securing television rights for games of the Leon soccer team, putting him in competition with other major television companies in Mexico.

Investments In Technology And Startups

Slim made notable investments in technology and startups during this period. In 2013, his company America Movil invested $40 million in Shazam, a mobile phone-based music identification service, to aid its growth in advertising and television in Latin America.
