Micron (MU) reported robust Q4 2025 results, with revenue of $11.32 billion and EPS of $3.03, surpassing consensus estimates by 0.47% and 5.94% respectively. The 46% year-over-year revenue growth was largely fueled by a 68.7% surge in DRAM revenue to $8.98 billion, despite a 4.8% decline in NAND revenue to $2.25 billion. These strong financials accompany a significant 41.4% stock return over the past month, indicating positive market sentiment.

Analysis

Micron (MU) delivered a strong fourth-quarter 2025 performance, exceeding consensus estimates on both revenue and earnings. The company reported revenue of $11.32 billion, a 0.47% beat over expectations and a significant 46% increase year-over-year, while EPS of $3.03 surpassed the consensus by 5.94%. This growth was overwhelmingly driven by the DRAM segment, which posted revenue of $8.98 billion, representing a 68.7% year-over-year surge and beating analyst forecasts. However, this strength was partially offset by a notable weakness in the NAND segment, where revenue declined 4.8% year-over-year to $2.25 billion, missing analyst estimates. This bifurcated performance highlights a dependency on the DRAM market cycle, likely fueled by demand from AI and machine learning applications. The company's stock has already seen a substantial run-up, returning +41.4% over the past month, indicating that high expectations were largely priced in ahead of the report.

Key Decisions for Investors

• Given the powerful 68.7% year-over-year growth in DRAM, investors should assess the sustainability of this segment's momentum as the primary driver of Micron's financial outperformance.
• The 4.8% revenue decline and analyst miss in the NAND segment is a material headwind; investors should closely monitor this segment for signs of stabilization or further deterioration in subsequent quarters.
• Following the stock's significant 41.4% rally in the past month, it is prudent to evaluate whether the strong earnings results are fully reflected in the current valuation or if further upside is justified by the underlying segment performance.
