Micron Technology (MU) shares closed near $1,064 on October 5, 2026, following blockbuster fiscal Q4 results released September 30 that showed revenue surging to $54.23 billion—well above consensus—and adjusted EPS of $33.42. AI-driven demand for high-bandwidth memory fueled record cloud and data-center segments, with gross margins expanding to 86.8% and a $32 billion backlog in long-term supply agreements. Analysts responded with upgrades and raised targets, citing multi-year visibility and tight supply conditions. The stock has climbed more than 500% over the past year amid semiconductor sector strength, though near-term movement will hinge on broader tech sentiment, Treasury yields, and any follow-through from the post-earnings guidance for fiscal Q1 revenue around $61.5 billion.
