SK Telecom (NYSE: SKM) today announced its consolidated earnings for the fiscal year 2025, based on Korean International Financial Reporting Standards (K-IFRS): revenue of KRW 17.0992 trillion and operating income of KRW 1.0732 trillion.

Year-over-year (YoY), revenue and operating income declined by 4.7% and 41.1%, respectively. Net income decreased 73.0% to KRW 375.1 billion.

On a non-consolidated basis, the company recorded revenue of KRW 12.0511 trillion and operating income of KRW 811.8 billion.

Following sustained efforts to overcome the impact of last year’s cybersecurity incident and restore customer trust. As of the end of 2025, 5G subscribers reached 17.49 million, an increase of about 230,000 from the third quarter. The number of fixed-line subscribers, including high-speed internet, also returned to pre-incident net growth levels in the fourth quarter.

In 2026, SK Telecom will place its top priority on Customer Value Innovation — the core of its business — while strengthening its fundamental competitiveness. The company aims to build a foundation for qualitative growth by reinforcing internal fundamentals with a focus on profitability.

Aiming for tangible results in 2026 with competitiveness in AIDC and AI models

In the artificial intelligence (AI) business, AI Data Center (AIDC) revenue reached KRW 519.9 billion, a 34.9% YoY increase. This performance was driven by higher utilization rates at the Gasan (Seoul) and Yangju (Gyeonggi) data centers and the acquisition of the Pangyo data center.

The Ulsan AIDC, a joint project with Amazon Web Services (AWS), has progressed smoothly since its groundbreaking in September 2025. In 2026, SK Telecom plans to break ground on an additional data center in Seoul. The company also plans to strengthen its AIDC solution business, while expanding its submarine cable business to generate synergies with its AIDCs.

SK Telecom successfully advanced to Phase 2 of the government-led Sovereign AI Foundation Model project in January 2026, gaining further momentum in strengthening its competitiveness in sovereign AI. Based on this achievement, the company expects to secure additional opportunities in various government-led AI initiatives.

Integrating AI across all telecommunications sectors to innovate customer value and restore profitability

In 2026, SK Telecom plans to apply AI across all areas of its telecommunications business — including products and marketing, networks and distribution channels — to enhance customer experience. For example, AI-driven automation across network design, deployment and operations is expected to improve customer value and drive productivity.

SK Telecom will also advance its AI-based Customer Lifetime Value (LTV)* modeling to provide personalized products, membership benefits and distribution channels tailored to individual preferences.
*Customer Lifetime Value represents the total value a customer generates over the entire period of using a particular service, serving as a critical metric that reflects the depth of the relationship between the company and its customers.

By accelerating its AI Transformation (AX), SK Telecom will focus this year on restoring profitability in its mobile business while strengthening its fundamental competitiveness to secure a foundation for mid- to long-term growth.

“This year, SK Telecom will drive customer value innovation across all areas of our telecommunications and AI businesses, and make every effort to improve our financial performance,” said Park Jong-seok, CFO of SK Telecom.
