SK Hynix commands a 56.4% share of the high-bandwidth memory market in the first quarter of 2026, according to IDC data, placing it ahead of U.S. rivals Micron and Sandisk. The South Korean company reported second-quarter revenue of 79.3 trillion Korean won, roughly 55 billion U.S. dollars, with a 76% operating margin, yet its stock sold off after results missed elevated consensus estimates. SK Hynix now trades at a forward price-to-earnings multiple of 5.5, compared with 5.9 for Sandisk and 12.0 for Micron. The article argues the valuation discount reflects temporary sentiment rather than operational weakness, presenting a potential buying opportunity in a leading AI memory supplier.
