Micron (MU) Q1 2026 earnings review
Vertical Ascent: Margins and Guidance Explode Higher
Micron is in the midst of a historic repricing event. Q1 revenue surged 57% YoY to $13.64B, but the real story is the guidance. Management forecasts Q2 revenue of $18.7B (+37% QoQ) and Non-GAAP Gross Margins jumping to 68%. The AI supply-demand imbalance has given Micron unprecedented pricing power, pushing Cloud Memory operating margins to 55%. The company is effectively printing cash, with Free Cash Flow hitting $3.9B despite a heavy $4.5B Capex spend.
🐂 Bull Case
Guidance for 68% gross margin in Q2 is unheard of for a hardware memory manufacturer. Cloud Memory Business Unit is already delivering 66% gross margins, confirming that HBM (High Bandwidth Memory) pricing is inelastic due to AI demand.
Revenue grew 21% sequentially, but Operating Income grew 62% ($3.95B to $6.42B). Every incremental dollar of revenue is dropping almost entirely to the bottom line.
🐻 Bear Case
With guidance doubling EPS sequentially to ~$8.42, the bar is set incredibly high. The cyclical nature of memory suggests that when supply eventually catches up, the fall from 68% margins could be steep.
To sustain this growth, Micron spent $4.5B on Capex in just one quarter. While covered by cash flow now, this annualized $18B run-rate creates high fixed costs if demand softens.
⚖️ Verdict: 🟢🟢
Strong Buy. The Q2 guidance represents a violent acceleration in fundamentals. Micron has successfully transitioned from a commodity cycle to a structural AI growth story with scarcity pricing power.
Key Themes
Cloud Memory Dominance
The Cloud Memory Business Unit (CMBU) is the engine room. Revenue hit $5.28B, but the shocking metric is the profitability: 66% Gross Margin and 55% Operating Margin. This confirms that data center AI demand is absorbing supply at premium price points without resistance.
Core Data Center Recovery
While Cloud Memory gets the headlines, the Core Data Center unit (traditional server/storage) woke up. Revenue surged 51% sequentially ($1.57B to $2.38B) and Operating Margin jumped from 25% to 37%. This indicates the recovery has broadened beyond just AI/HBM into general compute infrastructure.
Inventory Efficiency vs. Risk
Micron is running lean. Inventory dollars actually fell ($8.35B to $8.20B) while sales skyrocketed. While this aids cash flow, it implies they are selling everything they make immediately. Any production hiccup or yield issue with HBM could result in missed revenue in this supply-constrained environment.
Mobile & Client Profitability Spike
Even the traditionally lower-margin Mobile & Client segment saw operating margins explode to 47% (up from 29% in Q4). This suggests pricing power is not limited to HBM; tight supply is lifting pricing across standard DRAM/NAND for phones and PCs as well.
Capex Velocity
Investments in capital expenditures were $4.5 billion in Q1. Management indicated this is necessary to support AI demand, but it is a massive outlay. If the AI cycle turns, this high level of spend will become a burden on Free Cash Flow.
Other KPIs
Beat expectations and shows incredible leverage. EPS grew 58% sequentially from $3.03 in Q4, outpacing the 21% revenue growth. This demonstrates the impact of gross margin expansion on the bottom line.
Accelerating. Up from $5.73B in the prior quarter. This massive cash generation is allowing Micron to fund $4.5B in quarterly Capex while still adding to its cash pile (now $12.0B liquidity).
Accelerating. Grew 20% sequentially and 49% YoY. While smaller than Cloud, the margin expansion here (7% to 36% YoY) is arguably the most impressive relative improvement in the portfolio.
Guidance
Accelerating. Implies +37% sequential growth vs Q1. This is a massive step-change, suggesting new capacity coming online is already sold out at higher prices.
Accelerating. Up from 56.8% in Q1. This level of profitability is historic for Micron and indicates a severe shortage in the memory market.
Accelerating. Implies near doubling of earnings sequentially ($4.78 -> $8.42). This guidance suggests the operating leverage story has not yet peaked.
Key Questions
Sustainability of 68% Margins
Guidance implies Gross Margins of 68%. Is this driven purely by HBM mix shift, or are we seeing structural pricing resets in legacy DRAM/NAND? How long can margins remain above 60% before customers push back or competitors flood supply?
Capex Trajectory
With $4.5B spent in Q1, should we model ~$18B for the full year? If margins normalize in FY27, does this level of capital intensity risk returning Free Cash Flow to neutral/negative?
Inventory Constraints
Inventory dollars decreased sequentially while revenue jumped. Are you currently production-constrained across all business units? How much revenue is being left on the table due to inability to supply?
Core Data Center Durability
Core Data Center revenue jumped 51% QoQ. Is this a one-time restocking event by traditional server OEMs, or a sustainable recovery in general purpose compute alongside AI?
