Mikati founded T-One, a US-based telecommunications company specialising in international services in 1994, whilst studying engineering at Columbia University. T-One was sold to a publicly traded US company in 1997. In 1998, he was appointed CEO of emerging market mobile phone company, Investcom.[2]
Investcom, founded in 1982, was a Middle Eastern mobile telecommunications network provider. Under Mikati's leadership, the company's sales grew from $30 million to close to $1 billion. In 2005, Investcom was added to the Dubai International Financial Exchange and the London Stock Exchange (LSE) in what was known to be the largest listing of a Middle Eastern company on the LSE, making Mikati the youngest CEO of a publicly traded Middle Eastern company at the time.[2]
The following year, Investcom was bought by the leading African mobile operator MTN for $5.5 billion.[3] Mikati was appointed Non-Executive Director of the MTN Group in July 2006.[citation needed]
