SK Telecom Co., Ltd.

Company Background

SK Telecom is South Korea's largest cellphone service provider. It began as a subsidiary of a state-owned communications company in 1984, providing car-phone services. In 1997, the company became a subsidiary of SK Group, South Korea's third-largest conglomerate in terms of asset size. The group engages in energy and fiber businesses.

SK, the holding company of SK Group, is SK Telecom's largest shareholder. SK Group chairman Chey Tae-won also has a stake in the company. It is listed on the Korea Stock Exchange and the New York Stock Exchange.

Improving the country's communications environment is a South Korean national project. SK Telecom has often launched the world's fastest communication services ahead of foreign rivals. Having electronics makers with a great degree of telecom-related expertise such as Samsung Electronics and LG Electronics at home is one of the company's strengths.

Given South Korea's population and economic growth rates are slowing, while the smartphone penetration rate is already high, the company needs to develop new revenue sources for further growth. The company's cellphone services in Mongolia, Vietnam and the U.S. have achieved limited success.

Business Summary

SK Telecom Co., Ltd. engages in the provision of wireless telecommunication and internet services. Its products include mobile phones, wireless data, information communication, and others. The company was founded on March 29, 1984 and is headquartered in Seoul, South Korea.
