Micron Technologies (MU) Ups HBM Ante vs. SK Hynix

Micron Technology is intensifying its competition with SK Hynix in the crucial high-bandwidth memory (HBM) market, a development that could reshape investor strategies in the AI semiconductor landscape. Micron has already shipped over $1 billion in HBM4 revenue, with its ramp progressing at double the pace of its HBM3E offering. This aggressive expansion directly targets SK Hynix's stronghold in AI accelerators.

Micron's strategic move is further bolstered by 16 take-or-pay agreements, projected to secure approximately $100 billion in floor-price revenue. The company's chief executive, Sanjay Mehrotra, has indicated that even at these minimum contract prices, gross margins are expected to surpass previous peak levels, suggesting a robust revenue and profitability outlook. This contract-centric approach contrasts with SK Hynix's reliance on established customer relationships and its strong ties with Nvidia.

SK Hynix, meanwhile, reported a record quarter in Korean won, driven by its HBM sales. Despite a minor earnings miss that led to an initial selloff in its ADRs, analysts largely maintained their positive ratings. Both companies' future performance hinges on the capital expenditure guidance from AI hyperscalers, making them key indicators of broader AI infrastructure investment trends. Micron's current valuation, with a forward price-to-earnings ratio of 6 against its substantial contract book, may present a disconnect from its underlying business potential.
