Micron (MU) delivered a blockbuster Q4 earnings report on September 30, crushing Wall Street estimates and proving the artificial intelligence infrastructure (AI) boom remains in hyperdrive.
Driven by surging global demand for High-Bandwidth Memory (HBM), the semiconductor giant posted unprecedented top- and bottom-line performance, with data center sales up 11x.
Revenue came in at a record $54.23 billion for the quarter – up sharply from $11.32 billion in the same quarter last year, while GAAP net income also reached an astounding $37.7 billion or $32.87 a share.
Micron stock is currently trading at more than 3x its price at the start of this year.
Why Micron stock is pushing higher after Q4 earnings
Beyond raw headline figures, Micron demonstrated pricing power in fiscal Q4 previously unheard of in the traditionally cyclical memory market.
Non-GAAP gross margins surpassed management’s aggressive target of 86%, demonstrating how strategic long-term customer agreements have insulated the firm from broader macro volatility.
HBM3E memory modules, which power next-generation graphic processing units for enterprise deep learning clusters, remain fully sold out deep into next year.
Operating cash flow swelled to $89.68 billion for fiscal 2026 – allowing Micron to simultaneously fund $27.37 billion in capital expenditures while sustaining robust liquidity reserves.
Crucially, the “14-week quarter” provided extra operational tailwinds, reinforcing MU’s transition from a commoditized chip maker into an irreplaceable AI infrastructure player.
Guidance suggests MU shares have more room to run
MU shares fell after the earnings release despite management issuing exceptionally strong Q1 guidance, projecting revenue of $61.5 billion, plus or minus $1.5 billion, and GAAP diluted EPS of $37.84.
This outlook confirms that server memory tightness will persist, despite rising competition from Chinese mainstream DRAM producers.
Note that Micron showed material strength across its broader portfolio in the fourth quarter.
Data center storage demand surged – led by “high-capacity” enterprise SSDs (eSSDs) that complement high-performance AI training and inference server deployments.
High-density server DRAM modules (DDR5) and LPDDR5X for AI-enabled edge devices also saw accelerated enterprise adoption, expanding MU’s footprint past traditional accelerators.
DRAM revenue rose to $38.26 billion in Q4 (representing ~70.5% of total quarterly revenue).NAND revenue surged to $12.32 billion in Q4 (representing ~22.7% of total quarterly revenue).High-capacity eSSDs (specifically 30TB+ and 60TB class drives) crossed the $1.5 billion quarterly run rate mark.
Micron confirmed over $100 billion in total cumulative long-term “take-or-pay” contract value locked in across top hyperscale cloud providers and AI GPU customers.
These binding contracts guarantee pricing floors and volume commitments, insulating Micron from standard cyclical price spot dips.
How to play Micron Technology after fourth-quarter earnings
Following the post-earnings breakout, investors should approach Micron shares with a strategic balance of momentum participation and risk management.
With shares up over 200% year-to-date, chasing extended green candles risks exposure to short-term pullback volatility.
A prudent approach involves writing cash-secured puts below key technical support levels to establish entries on dips or holding core long equity while selling out-of-the-money covered calls to harvest elevated option premiums.
Given MU’s long-term order visibility and structural gross margin expansion, dollar-cost averaging on temporary macro consolidations allows long-term investors to participate in the multi-year AI memory super-cycle without overextending capital at local peaks.
