**Revised Forecast Information** 

On July 4, 2025, SK Telecom Co., Ltd. (the "Company") announced a revised guidance on its forecasted consolidated operating revenue and operating profit for the fiscal year 2025, which had originally been disclosed in the Company's current report on Form 6-K entitled "Future Business or Management Plans" furnished by the Company on February 12, 2025, in light of the recent cybersecurity incident experienced by the Company. The details of such revised guidance are as follows:

---

| 2025 Business Guidance (Revised) | 2025 Business Guidance (Revised) |
| - Forecasted Operating Revenue: | Won 17.0 trillion |
| - Forecasted Operating Profit: | a decrease compared to fiscal year 2024 |

---

The revised forecast information above reflects the estimated impact of the implementation of the customer appreciation package (estimated to amount to approximately Won 500 billion) related to the cybersecurity incident experienced by the Company earlier in 2025, as well as recent results of operations of the Company and its analysis of industry and market conditions, among other factors. Such information remains subject to change depending on the Company's future operating conditions and business environment, among other factors.

Details relating to the customer appreciation package will become available on the Company's website (www.sktelecom.com) at a future date.
