SK Telecom (NYSE: SKM) reports treasury share disposal tied to stock options

Rhea-AI Filing Summary

SK Telecom Co., Ltd. reported the disposal of 14,621 treasury common shares between February 4 and March 25, 2026, at aggregate proceeds of 1,161,969,600 Won. The shares were transferred to officers and employees in connection with stock options granted at the 2021 annual general meeting of shareholders.

The company used a “compensation in treasury shares for the difference in price” method, delivering shares equal in value to the difference between each option’s exercise price and the closing market price, after withholding taxes. Because this settlement method depends on market prices at exercise, the actual 14,621 shares disposed differed from the 71,726 shares originally estimated as subject to disposal in the initial report.

Report on Disposal of Treasury Shares

From February 4, 2026 to March 25, 2026, SK Telecom Co., Ltd. (the “Company”) disposed of a portion of its treasury shares.

1. Report on Disposal

A. Date of the Report of Decision on Disposal of Treasury Shares (the “Initial Report”): January 28, 2026 (Please refer to the current report on Form 6-K furnished by the Company on January 28, 2026.)

B. Period of Disposal: February 4, 2026 – March 25, 2026

C. Type and Number of Disposed Shares: 71,726 common shares

2. Details of Disposal

Date(1)		Type		Number								Disposal Price per Share (Won)(2)				Aggregate Disposal Price (Won)(2)				Recipient of Shares				Investment Brokerage Agent

(1) Refers to the actual date on which treasury shares were transferred as a result of the exercise of stock options. In accordance with Korean disclosure regulations, the period of disposal set forth in the Initial Report covers the period from the first date on which treasury shares were delivered upon exercise of stock options (granted pursuant to a resolution of the same general meeting of shareholders or the board of directors) until the end of the exercisable period.

(2) Based on the market closing price on the date of the disposal.

3. Discrepancy with the Initial Report

The actual number of disposed shares was 14,621 common shares, compared to 71,726 common shares that were estimated to be subject to disposal as set forth in the Initial Report.

This report concerns the disclosure of disposal of treasury shares due to the exercise of stock options granted at the annual general meeting of shareholders held in 2021 (the “2021 Annual General Meeting of Shareholders”). In accordance with Article 5-9 of the Regulation on Securities Issuance and Disclosure, the number of treasury shares to be disposed of includes all stock options granted at the 2021 Annual General Meeting of Shareholders, excluding those that have expired.

As all stock options exercised were settled using the “compensation in treasury shares for the difference in price” method, the Company transferred treasury shares equivalent in value to the difference between the exercise price and the closing market price on the exercise date (after deducting applicable withholding amounts including taxes).

As a result, a discrepancy arose between the number of shares estimated to be subject to disposal as set forth in the Initial Report and the actual number of disposed shares.

FAQ

What treasury share disposal did SK Telecom (SKM) report in March 2026?

SK Telecom reported disposing of 14,621 treasury common shares from February 4 to March 25, 2026, for officers and employees. These transactions were tied to the exercise of stock options granted at the 2021 annual general meeting of shareholders, using existing treasury shares rather than issuing new stock.

How much did SK Telecom (SKM) receive from the treasury shares disposed?

The aggregate disposal price was 1,161,969,600 Won for the 14,621 treasury shares transferred to officers and employees. Individual disposals were priced between 77,900 and 80,000 Won per share on different dates, reflecting the specific settlement terms linked to stock option exercises.

Why did SK Telecom’s actual disposed shares differ from the initial estimate?

The company originally estimated 71,726 treasury shares might be disposed, but only 14,621 were actually transferred. All options were settled using compensation in treasury shares for the difference between the exercise price and closing market price, so market-based calculations caused a gap versus the initial estimate.

Who received the treasury shares SK Telecom disposed of in early 2026?

All disposed treasury shares were delivered to officers and employees of SK Telecom. The transfers arose from stock options granted at the 2021 annual general meeting, and the company used SK Securities Co., Ltd. as the investment brokerage agent for executing these share disposals.

What does SK Telecom’s filing say about its treasury share position?

The filing lists 1,789,157 common shares, representing 0.83 percent of total shares, with a value of 87,988 million Won in the treasury share table. This figure provides context for the size of the company’s treasury stock position relative to the smaller disposal related to stock option exercises.

How were SK Telecom’s treasury share disposals structured by date and price?

Treasury shares were disposed on four dates: February 4, 12, 27, and March 26, 2026. Per-share disposal prices ranged from 77,900 to 80,000 Won, with share counts from 1,150 to 8,630 per date, reflecting transaction-specific pricing linked to option exercise settlements.
