SK Hynix Jumps 8% After a 632% Profit Surge and a $45 Billion Shareholder Pledge. Micron and SanDisk Are Riding Along.
SK Hynix (SKHY) reported a 632% increase in operating profit and a $45B shareholder return plan, causing its shares to rise 8% premarket. Micron (MU), SanDisk (SNDK), and Western Digital (WDC) also saw gains. SKHY's revenue and operating profit set records, but net profit missed estimates. The company's pledge follows shareholder demands for better payouts.
