AI infrastructure stocks fall on rising debt concerns
Companies building the infrastructure for AI are facing questions about the massive amounts of cash they are spending on data centers and specialized chips. While these investments are necessary to meet demand, they often require taking on significant debt before the new facilities start earning money.
This is a direct concern for SK Telecom as it tries to pivot from a traditional phone company into an AI data center hub. The company is currently building out large-scale power capacity for these sites, and its ability to manage these costs without hurting its core cash flow is the main thing to watch.

Reliance Jio seeks $108 billion valuation for Indian telecom IPO
Reliance Industries is looking to value its telecom arm, Jio, at over $100 billion in what would be a landmark stock market debut. Jio has rapidly become the dominant player in India by offering low-cost data and digital services to hundreds of millions of users.
While this happens in a different market, it shows that investors are still willing to pay high prices for telecom companies that successfully move beyond basic phone service into broader digital infrastructure. It provides a useful comparison for SK Telecom's own attempt to rebrand itself as an AI-focused utility.
Management has turned a corner after a difficult 2025, delivering three straight quarters of results that significantly outpaced their own forecasts as the new AI business begins to contribute.

Key highlights
Profit growth accelerating: Net income, meaning the total profit after all expenses, jumped 459.76% to KRW 470.60 billion as the company benefitted from significantly higher operating margins. This surge shows the business is becoming much more efficient at turning its KRW 4.36 trillion in revenue into actual earnings for owners.
Main business efficiency gains: Operating income from the company's core services grew 67.34% to KRW 566.0 billion compared to the same time last year. Even though revenue only grew 0.47%, the company is keeping far more of every dollar it earns by controlling its internal costs.
Mobile market share holding: The company maintained its dominant position in the Korean mobile market with a 45% share of subscribers. This stability provides a reliable foundation of cash flow while the company attempts to transition into an artificial intelligence business.
Network technology adoption rising: The 5G penetration rate, which measures how many mobile customers have upgraded to the faster network, reached 68%. This is up from earlier periods and is a key driver for long term growth because 5G customers typically pay higher monthly fees than older network users.
Spending outlook lowered: Management expects capital expenditures, which is the money spent on physical infrastructure like towers and data centers, to remain disciplined at approximately KRW 2.1 trillion for the full year. This level of spending is lower than the KRW 2.4 trillion spent last year, which should leave more cash available for shareholder returns.
Our take: This was a remarkably efficient quarter that proved the business can grow its bottom line even when sales are flat. The 67.34% jump in operating profit shows the core telecom business is a cash machine. While we would like to see faster revenue growth, the massive improvement in profitability strengthens the long-term case for owning this stock.
