What Stops the AI Memory Boom? It Might Have Nothing to Do With Chips.
SK Hynix (SKHY) rejected a prepayment for power costs, citing high expenses, while reporting Q2 revenue up 257% and net profit up 1,240% YoY. The company's strong HBM relationship with NVIDIA (NVDA) provides pricing leverage amid Korea's power shortage. SK Hynix is diversifying geographically, breaking ground on a U.S. production base. The company's valuation remains attractive, with a trailing P/E of 11x and forward P/E of 5x, and it plans to accelerate share repurchases.
