Fixed-line subscribers, including high-speed internet users, also returned to pre-incident net growth levels in Q4.
In 2026, SK Telecom will prioritise Customer Value Innovation while strengthening its fundamental competitiveness, with a clear focus on improving profitability and laying the groundwork for sustainable, long-term growth.
AI Business Gains Momentum
SK Telecom’s artificial intelligence business continued to gain traction during FY 2025. Revenue from AI Data Centers (AIDCs) reached KRW 519.9 billion, representing a strong year-on-year growth of 34.9%, driven by higher utilisation rates at the Gasan (Seoul) and Yangju (Gyeonggi) data centres, as well as the acquisition of the Pangyo data centre.
The Ulsan AIDC, a joint project with Amazon Web Services (AWS), progressed steadily following its groundbreaking in September 2025. Looking ahead, SK Telecom plans to break ground on an additional data centre in Seoul in 2026, strengthen its AIDC solution business, and expand its submarine cable operations to create synergies with its data centre infrastructure.
The company also advanced to Phase 2 of the government-led Sovereign AI Foundation Model project in January 2026, reinforcing its competitiveness in sovereign AI and positioning it to capture further opportunities in government-driven AI initiatives.
Driving AI Integration Across Telecommunications
As part of its accelerated AI Transformation (AX) strategy, SK Telecom plans to integrate AI across all areas of its telecommunications business in 2026, including products and marketing, network operations, and distribution channels. AI-driven automation in network design, deployment, and operations is expected to enhance customer experience, improve productivity, and support profitability recovery.
The company will also advance its AI-based Customer Lifetime Value (LTV) modelling to deliver more personalised products, membership benefits, and distribution experiences tailored to individual customer preferences.
Commenting on the outlook, Park Jong-seok, CFO of SK Telecom, said, “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.”
The conference call discussing SK Telecom’s FY 2025 earnings results will be available via the company’s website on February 5, 2026, from 16:00 Seoul Time.
