KT vs LUMN Comparison

KT is South Korea's largest fixed-line telecom operator, with around 11.5 million fixed-line broadband customers and 9.5 million IPTV customers, and is the second-largest wireless operator with 28 million subscribers. Additionally, it has a number of nontelecom businesses, including real estate, payment processing, artificial intelligence, and IDC/cloud services, many of which are the focus of its growth strategy. The company was formed from the previously government-owned, monopoly telecom business and was listed in 1998. After selling its mobile business in 1994 (forming its mobile competitor, SK Telecom) KT created its own mobile operator in 1997.

Lumen Technologies is one of the largest telecommunications carriers serving global enterprises. The merger with Level 3 in 2017 and the 2022 divestiture of much of its local phone business in rural areas and small markets shifted the company's operations away from the legacy consumer business and toward enterprises services, which account for about 75% of revenue. Lumen offers businesses a full suite of communications services, providing colocation and data center services, data transportation, phone service, and internet access. Lumen has announced the sale of its remaining consumer fiber network to AT&T, which will further shift its focus to enterprise customers.
