Key Drivers of the MU Stock Move

Micron (MU) stock beat Q4 2025 estimates with EPS of $3.03 vs. $2.86 expected and revenue of $11.32B vs. $11.22B. The company guided Q1 2026 EPS to $3.60–$3.90, far above the $3.04 consensus.
Options activity spiked with $7.4M in premiums traded on September 24. Flows showed mixed sentiment, with bullish calls and protective puts clustered around the $160–$170 strikes.
CEO Sanjay Mehrotra announced HBM4 will launch in 2026 and that Micron has secured pricing for most HBM3E supply through 2026. As the only U.S.-based memory manufacturer, Micron is positioning itself at the center of the AI boom.

Micron’s robust quarterly results were fueled by surging AI infrastructure demand, prompting management to lift its 2025 server unit growth forecast to about 10% from mid-single digits. CEO Sanjay Mehrotra said the company is poised to capture a share of the “trillions” in AI investments, much of which will flow into advanced memory products.
