Micron (MU) Stock Jumps to Fresh High After Record FY2026 Q1 Results and a Blockbuster AI Memory Forecast — What Investors Are Watching on Dec. 19, 2025
Micron Technology, Inc. (NASDAQ: MU) is extending a powerful rally on Friday, December 19, 2025, after a record fiscal first-quarter report and an outlook that shocked Wall Street with just how tight the memory market has become in the AI era. Shares traded around $267 in mid-day action, up about 7% on the session, after touching an intraday high of $268.08. The surge follows Micron’s record fiscal Q1 2026 results (quarter ended Nov. 27, 2025) and an aggressive fiscal Q2 2026 forecast that reflects soaring pricing and demand for DRAM, NAND, and especially high-bandwidth memory (HBM) used in AI servers.
