Disposition of 110,000 Treasury Shares for Stock Option Exercise

Hansol Chemical decided on May 18, 2026 to dispose of 110,000 treasury shares (common stock) for stock option exercise
The shares are the remaining portion of stock options granted at the 2020 AGM, excluding 35,000 already exercised via new share issuance
This follows the 2026 AGM approval of a change to treasury stock delivery type for the stock options
Disposition amount is based on exercise price; shares will be transferred from treasury account to individual accounts
Disposed shares represent less than 1% of total issued shares, so dilution effect is expected to be minimal
