MU result

After the event it went to −3.96% at its lowest, and later to +3.17% at its highest, against the close price before Fiscal Q4 2026 earnings.

The news wasMixed

The numbers were unambiguously good and the spending behind them was not. Revenue, margin, earnings and the next quarter's guide all came in above what the company had told the market to expect, and management called an 86.25% gross margin the floor for fiscal 2027 rather than the peak. Against that, first-half fiscal 2027 capital spending of about 25 billion dollars is roughly 91% of the whole of fiscal 2026 in half the time, research and development rises by more than 1 billion dollars, and a planned pay increase adds to costs. In memory, spending on that scale reads as future supply, which is the one thing a market paying about 7 times forward earnings is braced for. The tape traded both readings in a single session before settling 3.03% higher.

Chart

Micron beat its own guidance on every line of fiscal Q4 2026, with revenue of 54.23 billion dollars, an 87.0% gross margin and 33.42 dollars of adjusted earnings, and guided the next quarter to a record 61.5 billion dollars with the margin called a floor. The market sold it anyway on a fiscal 2027 capital plan of about 25 billion dollars in the first half alone, taking the stock to $1022.90 on the morning of 1 October before it reversed to close at $1097.39, up 3.03% on the day.

What else moved the price

Little of the move came from outside Micron. On 1 October SPY rose 0.18% and QQQ 0.31%, so the index contributed almost nothing to a 3.03% session. The semiconductor complex did move, but mostly downstream of this release rather than alongside it: SMH rose 1.45%, and the three equipment names the card had tied to the capital spending line, AMAT at 3.50%, LRCX at 3.53% and KLAC at 2.77%, were reacting to Micron's own capital plan. Press coverage of the day also noted Treasury yields retreating from their highest levels in more than twenty years, which helped the broad tape recover from early losses, but the index close of 0.18% caps how much of Micron's session that can explain. The larger prices in this window were not the earnings at all. The stock fell 11.78% from the $1023.15 signal price to $902.60 on 14 September with no Micron news found to match it, then rose 22.84% from there to the $1108.72 high on 25 September, both moves larger than the result itself produced.

    What happened

    1. 28 Sept 2026, 00:00 UTC

      Baird raised its Micron target to $1,520 from $1,280 and kept Outperform

      Baird lifted its price target on 28 September 2026, citing a surge in agentic AI demand, slower industry-wide DRAM supply bit growth in 2027 than in 2026, and a higher margin profile for high bandwidth memory next year. The new target implied about 40% upside from the 25 September close. It supports the scarcity argument this card rests on without changing any figure the card gave.

    2. 28 Sept 2026, 00:00 UTC

      JPMorgan reiterated Overweight with a $1,540 target ahead of the results

      JPMorgan analyst Harlan Sur restated an Overweight rating and a $1,540 price forecast on 28 September 2026, pointing to stronger customer demand signals, a view that calendar 2027 could prove tighter than 2026, and continued growth in high bandwidth memory production. This is the same supply-shortage case the card describes, restated two days before the print.

      Citi raised its Micron target to $1,300 from $1,150 and kept Buy

      On 23 September 2026 Citi analyst Atif Malik lifted his Micron price target to $1,300 from $1,150 and raised his estimates for the quarter being reported. He cited DRAM prices rising faster than he had modelled on the roughly 60% of output not locked into long-term contracts, and supply staying tight beyond 2027. It adds to the expectations the results on 30 September will be measured against.
