4.

Moreover, pursuant to Article 176-6(2) and Article 176-5(1)(ii) of the Enforcement Decree of the FSCMA, in the case of a share exchange between a listed company and an unlisted company, the exchange price of the listed company may be determined by applying a premium or discount within

a range of 10 percent to the value calculated in accordance with the method described above. The Share Exchange constitutes a share exchange between affiliated companies, and, as agreed upon following review by and mutual negotiations between the boards of directors of SK Telecom and SK Broadband, the reference market price calculated as described above has been applied as the share exchange price for SK Telecom without any premium or discount.

•

Volume-weighted average closing share prices over the most recent one-month period (February 26, 2026 – March 25, 2026): Won 77,511

•

Volume-weighted average closing share prices over the most recent one-week period (March 18, 2026 – March 25, 2026): Won 77,946

•

Closing share price on the most recent day (March 25, 2026): Won 79,800

•

Reference market price (arithmetic mean): Won 78,419

2) Asset value of parent company (SK Telecom)

The asset value per common share of SK Telecom was calculated, pursuant to Article 5 of the Enforcement Rules of the Regulations on the Issuance and Disclosure of Securities, by dividing the net asset value (determined by adjusting certain items from the total shareholders’ equity shown in the separate financial statements as of the end of the most recent fiscal year preceding the fiscal year in which the major event report is submitted) by the total number of issued shares as of the valuation base date. The details of the calculation of the asset value per common share of SK Telecom Co., Ltd. are as follows:

•

Total shareholders’ equity (based on the separate statement of financial position as of the end of the most recent fiscal year): Won 11,991,050 million

•

Adjustment items: Won 665,748 million

•

Additions: Won 1,404,213 million

•

Deductions: Won 738,465 million

•

Adjusted net asset value: Won 12,656,798million

•

Total number of issued common shares: 214,790,053 common shares

•

Asset value per common share: Won 58,926

Pursuant to Article 176-5(1)(2)(a) of the Enforcement Decree of the FSCMA, the share exchange price of a listed company shall, in principle, be based on the reference market price; provided, however, that where the reference market price is lower than the asset value, the asset value may be used instead.


		In the case of SK Telecom, a listed company, the reference market price exceeds the asset value, and accordingly, the reference market price was used to determine the share exchange price. • Reference market price: Won 78,419 • Asset value per common share: Won 58,926 • Share exchange price: Won 78,419 (2) Pursuant to Article 176-5 of the Enforcement Decree of the FSCMA, Article 5-13 of the Regulations on the Issuance and Disclosure of Securities, and Articles 4 through 6 of the Enforcement Rules thereof, the share exchange price of an unlisted company is required to be determined based on its intrinsic value (calculated as the weighted arithmetic mean of the asset value and the profit value at weights of 1 and 1.5, respectively). Accordingly, in calculating the share exchange price of SK Broadband, an unlisted company, its intrinsic value was applied. • Asset value: Won 7,011 • Profit value: Won 20,379 • Intrinsic value (weighted arithmetic mean): Won 15,032 • Share exchange price: Won 15,032 (3) Calculation of share exchange ratio The share exchange ratio of the Share Exchange is 1 (SK Telecom) to 0.1916882 (SK Broadband). In lieu of issuing new shares, SK Telecom intends to pay cash consideration of Won 15,032 per common share to shareholders of SK Broadband other than SK Telecom.
