How it's calculated

US ADR (SKHY): 10 ADS = 1 ordinary share. Parity per ADS = 000660 price ÷ USD/KRW ÷ 10. Premium = SKHY ÷ parity − 1.
Frankfurt GDR (HY9H): 1 GDR = 1 ordinary share. Parity per GDR = 000660 price ÷ EUR/KRW. Premium = HY9H ÷ parity − 1.
SK Square NAV discount: NAV (simplified) = SK Square's SK hynix stake (146,100,000 shares, per SK hynix IR as of 2026-05-06) × 000660 price. Discount = 1 − SK Square market cap ÷ NAV.

Positive values are shown in green (premium), negative in red (discount). For SK Square, a positive "discount" means the market cap is below the value of its SK hynix stake alone.
