Algar Telecom is a Brazilian telecommunications company, currently operating in multiple states including Goiás, Mato Grosso do Sul, Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, São Paulo, and the Federal District. The company was founded as Companhia Telefônica da Borda do Campo (CTBC) on February 15, 1954, by Alexandrino Garcia in Uberlândia, State of Minas Gerais. Garcia acquired Companhia Telefônica Teixeirinha to start his venture in the telephony industry. The company initially focused on the rural regions of Central Brazil, later expanding to other regions and major Brazilian capitals.
The company transitioned from CTBC to Algar Telecom in 2013, a strategic branding decision by the parent company, Grupo Algar. In 2007, Algar Telecom became a publicly traded company, though it is not listed on stock exchanges. The company's ownership saw a significant change in December 2017 when Grupo Algar announced the sale of a 25% stake in Algar Telecom to Archy, a subsidiary of Singapore's sovereign wealth fund GIC Private Limited. This sale is currently pending regulatory approval by Brazil's federal telecommunications regulatory agency Anatel and the Brazilian government's competition regulator CADE.
