Micron is down about 3% as the market keeps focusing on the cost side of its AI-memory buildout rather than the headline strength in recent results. Investors have been reacting to Micron’s plans to push fiscal 2026 capital expenditures above $25 billion, alongside commentary pointing to even heavier spending into 2027, raising concerns about future cash flow and the risk of overbuilding capacity into the next part of the memory cycle.

Micron’s recent earnings print and guidance were strong enough to lift expectations, but the stock has faced a classic post-report reset as traders lock in gains and reprice risk. With the shares having run up sharply earlier in 2026, even good news can be treated as fully reflected in the price—leaving capex intensity and longer-term margin durability as the key debate.

Near-term attention is on whether Micron can translate aggressive investment into sustained high margins without triggering a supply-driven downturn. Watch for updates on wafer-fab equipment and HBM capacity expansion timing, any additional commentary on fiscal 2027 spending, and whether analysts shift targets or ratings based on free-cash-flow sensitivity rather than earnings power.
