SKT rebounds on stronger mobile, broadband sales
SK Telecom reported a Q3 net profit of KRW 412 billion ($310M), reversing last year's KRW 167 billion loss. Revenue rose 13.1% to KRW 4.5 trillion ($3.36B), driven by 21.6% growth in mobile services and 7.4% in broadband. The company spun off its data center business and plans to launch 5G standalone services next month. Its stock closed 4.2% higher on Wednesday.
How this was made

The 30-second read
Why it matters
The key tradable takeaway is the combination of profitability turnaround plus operational KPIs (mobile ARPU, gigabit take-up, AI DC utilization) and forward operational milestones (5G standalone commercial services next month).
Market read
A company-specific earnings print with segment growth metrics and a same-day stock reaction provides a timely catalyst for telecom and data-center infrastructure sentiment.
What to watch
The article notes interest-rate sensitivity for outside funding and ongoing discussions with long-term customers, which could delay monetization of the AI DC spinoff plans.
Background
SK Telecom previously suffered a major customer data leak and a fine, with operating profit collapsing last year; this quarter frames a rebound and ongoing recovery.
Ticker impact
SK Telecom reported Q3 net earnings of KRW 412B and revenue up 13.1%, citing mobile and broadband growth as the driver.
Likely upward pressure as the market prices in improving operating momentum and reduced post-breach recovery risk.

Market effects
