Material Changes and Segment Performance
- Wireless Segment: Revenue was 6,497,465 million Won. The segment maintains a mature 5G subscriber base of 17.97 million (82% of total subscribers). Operating profit increased to 847,784 million Won.

- Profitability Drivers: The significant increase in net profit (76.4% YoY) is largely attributed to a substantial valuation gain on financial assets at Fair Value through Other Comprehensive Income (FVOCI), which contributed approximately 1.87 trillion Won to other comprehensive income, and improved operating efficiency.
- Dividends: The Board approved a quarterly cash dividend of 830 Won per share for the second quarter of 2026. The company maintains a policy of returning at least 50% of adjusted profit to shareholders.

- Capital Allocation: Track the execution of the 750 billion Won capital contribution to the new AI data center subsidiary (SK Hyper) and its impact on future cash flows.
- Dividend Sustainability: Confirm the company's ability to maintain its 50% adjusted profit payout ratio given the volatility in investment income.
