SK Telecom announced its Q3 2026 financial results, reporting an operating profit of 552.3 billion won (approximately $410.8 million), a significant recovery from a 166.7 billion won loss in the same quarter last year due to a SIM information leak. The company attributed this rebound to the absence of one-off expenses related to customer compensation and a recovery in telecom revenue. Revenue increased by 13.1% year-over-year to 4.4973 trillion won (approximately $3.3 billion). The results exceeded market expectations, with actual revenue and operating profit surpassing forecasts by 1.3% and 3.8%, respectively. The AI data center business also showed growth, although its revenue fell slightly from the previous quarter. The company has been focusing on stabilizing marketing costs and enhancing its AI data center operations. The financial recovery indicates a normalization of operations following the significant impact of the data breach last year.
