Micron’s fiscal 2026 third-quarter surprise put memory semiconductor ETFs back in front. After the June 24 close, the company posted adjusted EPS of $25.11 and revenue of $41.46 billion, proving that AI infrastructure demand is also a memory story, not only a GPU trade.
Numbers That Changed the Tape
Market expectations sat near $20 to $21 in EPS and about $36 billion in revenue. Micron beat both, revenue more than quadrupled from a year earlier, and gross margin rose into the mid-80% range. At 1,370 won per dollar, quarterly revenue equals about 56.8 trillion won; the roughly $50 billion next-quarter revenue view equals about 68.5 trillion won.
ETF Impact
AI inference requires fast HBM, DRAM and NAND, while new memory supply takes years to add. That supports prices, margins and earnings revisions for Micron and for ETF baskets tied to memory, equipment, materials and storage.
Korean Market Lens
Korean investors should compare U.S.-listed ETFs with Korea-listed overseas semiconductor ETFs by Micron weight, hedge policy, tax treatment and exposure to Samsung Electronics and SK hynix. Near term, pure memory exposure is positioned to benefit; the main risks are a peak in memory pricing, slower AI server spending and dollar-won volatility.
