SK Hynix and Sandisk Report Massive AI-Driven Revenue Growth

SK Hynix and Sandisk reported significant increases in sales and earnings fueled by the rising demand for artificial intelligence memory. SK Hynix saw second-quarter sales climb 257% to $52.6 billion, while Sandisk reported a 371% revenue increase to $8.9 billion in its fiscal 2026 fourth quarter.

Both companies capitalized on a global memory shortage to raise prices, leading to high operating margins of 76% for SK Hynix and approximately 79% for Sandisk. Sandisk CEO David Goeckeler stated that the transition toward AI agents is redefining storage requirements, creating a "very, very robust demand environment."

While Sandisk operates exclusively in the NAND flash market, SK Hynix maintains a diversified portfolio. SK Hynix currently controls 50% of the high bandwidth memory market and 25% of the DRAM market.
