Micron Technology reported record fiscal fourth-quarter 2026 results on September 30, with revenue reaching $54.23 billion and non-GAAP EPS of $33.42, both surpassing consensus estimates amid surging AI-driven demand for high-bandwidth memory. The company lifted long-term supply commitments to $32 billion and issued strong fiscal first-quarter 2027 guidance of $61.5 billion revenue plus or minus $1.5 billion, supporting expectations for sequential growth through the year. During the week of September 28, MU shares traded in a range near $1,032–$1,085 with closes around $1,054–$1,065, reflecting elevated valuations after a multi-year rally and heightened trading volume around the earnings catalyst. Traders are weighing these fundamentals against potential supply constraints and capital expenditure increases in a tight memory market.
