SK Hynix completes KRW 40 trillion share buyback, cancelling 3.3% of its stock

SK Hynix (000660.KS) finished a KRW 40 trillion treasury‑stock repurchase on October 21, a month ahead of the originally scheduled November 19 deadline. The program bought back 24.07 million shares, representing about 3.3% of the company’s issued shares, and the shares will be cancelled. The company said it will disclose further shareholder‑return measures when it reports its third‑quarter results on October 28.

The cancellation of 3.3% of outstanding shares reduces the float, which could tighten supply and support the stock price. The end of the buyback removes a major source of demand that had helped absorb foreign selling in South Korea’s semiconductor sector, leaving the market to find new buyers.
