SK Telecom Posts 67% Profit Jump as AI Data Centers Drive Growth

Telco Pivots to Infrastructure

SK Telecom reported operating profit of 566 billion won ($397 million) for the second quarter, a 67.3 percent increase from the same period last year, according to preliminary earnings disclosed Wednesday. The Seoul-based carrier attributed the gain to accelerating revenue from its data center operations, a segment that has become central to its diversification strategy as traditional mobile subscriber growth plateaus across mature Asian markets.

Net profit climbed 460.1 percent year-on-year to 466 billion won, while revenue inched up 0.5 percent to 4.36 trillion won. Both profit figures exceeded analyst consensus, though the top line came in slightly below forecasts. The divergence underscores a broader pattern among Asia-Pacific telecommunications incumbents: margin expansion through capital-intensive infrastructure plays, even as core connectivity revenue stagnates.

Data Center Demand in Context

The profit surge reflects rising enterprise and cloud-provider appetite for colocation and compute capacity in South Korea, a market that sits at the intersection of Northeast Asian manufacturing supply chains and cross-border data flows. Hyperscalers building out regional points of presence have leaned on local carriers for rack space, power, and low-latency connectivity to production clusters in Samsung and SK Hynix fabs.

SK Telecom has been expanding its data center footprint since 2023, when it committed capital to modular facilities designed for high-density GPU workloads. That timing positioned the company to capture a wave of generative AI training and inference demand that began accelerating in late 2025. Competitors including KT and LG Uplus have announced similar buildouts, but SK Telecom's earlier entry and scale advantages have translated into higher utilization rates and pricing power.

Revenue Growth Lags Profit Momentum

The modest 0.5 percent revenue increase signals that data center margin contribution is outpacing absolute growth in billings. Mobile service revenue, which still accounts for the majority of SK Telecom's top line, has been essentially flat as postpaid subscriber additions slow and regulatory pressure on roaming and overage fees persists. The company has offset some of that drag with enterprise 5G private network contracts and IoT connectivity deals, but those segments remain subscale relative to consumer wireless.

Investors have largely welcomed the profit mix shift. SK Telecom's share price has outperformed the broader KOSPI index by twelve percentage points over the past six months, a premium that reflects confidence in the durability of data center cash flows. Management has signaled it will reinvest a portion of the windfall into edge computing nodes and subsea cable consortia, both of which extend the infrastructure moat.

Regional Dynamics

South Korea's data center market is tightening. Available wholesale colocation capacity in the Seoul metropolitan area dropped below ten percent in the first quarter, according to industry surveys, and power allocation from Korea Electric Power Corporation has become a binding constraint for new projects. SK Telecom's existing grid connections and pre-secured land parcels give it a near-term advantage, but the window for easy expansion is narrowing.

Across the region, incumbent telcos are pursuing parallel strategies. Singtel's data center REIT has been buying assets in Singapore and Australia; China Mobile is partnering with provincial governments to build AI-optimized facilities in tier-two cities; and Telstra is pitching edge compute to mining and logistics customers. The common thread is a search for higher-return uses of legacy real estate and fiber networks as voice and SMS revenue continues its structural decline.

What Comes Next

SK Telecom's third-quarter performance will hinge on whether it can sustain utilization rates as new supply comes online from competitors. The company has not disclosed contracted versus spot pricing for its data center capacity, leaving open the question of how much of the current margin lift is structural versus cyclical. If hyperscaler demand moderates or power costs spike, the profit trajectory could flatten.

For now, the carrier is riding a favorable confluence: strong AI infrastructure investment, limited domestic competition for premium sites, and a regulatory environment that has not yet imposed data localization requirements strict enough to fragment capacity. That combination is unlikely to persist indefinitely, but it has given SK Telecom a profitable bridge as it navigates the long transition away from pure-play telecom economics.
