SK Hynix to Significantly Expand HBM4 Production Capacity in Late 2026
SK Hynix has announced plans to substantially increase its High Bandwidth Memory 4 (HBM4) production capacity starting in the second half of 2026. The company has secured long-term supply agreements (LTAs) with ten major industry clients for chip deliveries. Looking ahead to the third quarter of 2026, SK Hynix anticipates a roughly 10% sequential increase in DRAM shipments compared to the second quarter. Furthermore, the company expects a slight increase, in the low single digits (1% to 4%), in NAND flash shipments during the same period. The LTAs incorporate a differentiated pricing structure, varying based on customer type and chip product characteristics, aiming to mitigate the severe cyclical fluctuations in memory prices. These agreements are expected to significantly enhance the certainty of the company's medium- to long-term orders and demand.
SK Hynix's strategic expansion of HBM4 capacity and its implementation of differentiated long-term supply agreements signal a proactive response to anticipated demand growth in advanced memory markets, particularly for AI applications. The company's pricing strategy aims to stabilize revenue streams against the inherent volatility of the semiconductor industry. This move could position SK Hynix to capture a larger share of the high-performance computing market, while the LTAs provide crucial demand visibility and financial predictability. Investors and competitors will be monitoring the execution of this capacity ramp-up and the competitive landscape for HBM technology over the next few years.
