Micron is in the strongest stretch in its history, and the September 30 report extended it. Revenue for the 14-week fiscal fourth quarter ended September 3 was $54.23 billion. That is $4.2 billion above the midpoint of the company's own June forecast. Management guided the 13-week December quarter to $61.5 billion and expects sequential revenue growth in every quarter of fiscal 2027. The soft spot is margin. The non-GAAP gross-margin guide of about 86.25% is a step down from fiscal Q4's 87.0%. Management attributes the dip mainly to incentive pay capitalized into inventory, plus startup and other costs, and calls fiscal Q1 the floor for fiscal 2027. The shares closed September 30 inside a six-week base and have not yet traded a full session on the report.

Quick Snapshot (as of 2026-09-30)
The call 🟡 Wait for the October 1 reaction, then buy a settled close above the base pivot · Entry $1,108.72 breakout · stop $959.51 · first target 52-week-high retest · high conviction
What it is US maker of DRAM (including high-bandwidth memory, HBM, for AI accelerators), NAND flash and NOR. DRAM was 73% of fiscal Q4 revenue and NAND 26%.
Why now Fiscal Q4 beat the June guide on revenue, gross margin and EPS. The fiscal Q1 2027 guide is $61.5B ± $1.5B. Management expects DRAM and NAND to stay supply-constrained through calendar 2028 and says it has no "line of sight" to balance.
Proof Fiscal 2026 revenue was $133.19B vs $37.38B. Fiscal Q4 operating cash flow was $43.97B and adjusted free cash flow $33.20B. There are 26 multi-year take-or-pay Strategic Customer Agreements carrying $32B of customer commitments, mostly cash deposits.
Objection Gross margin sits at a record while price increases are set to moderate. Fiscal 2027 capex is rising above prior plans. Memory cycles have historically ended when supply caught up.
Stock setup A long uptrend that is intact but extended: well above its 200-day, in a six-week base below its 52-week high. The tape line below carries the numbers.
Next event October 1 first full session. Then the fiscal 2026 10-K and a larger buyback authorization, which management said on the call it will seek in the near term.

Action Matrix (as of 2026-09-30)

Signal Condition Level Why
🟡 Wait Let the October 1 session settle — The report has not been traded in a full session. An after-hours quote is not a close.
🟢 Buy Settled close above the 6.4-week base pivot on above-average volume $1,108.72 Completes the bottom → pop → flag → breakout sequence inside an intact long trend.
🔴 Out Settled close below the support shelf $959.51 Base failure. It caps the loss at 13.5% from the trigger, tighter than the 200-day stops that let past calls lose 20–40%.
🟠 Target Retest of the 52-week high 52-week high First objective. Trim or trail there.
🔴 Thesis breaks Fiscal Q1 2027 non-GAAP gross margin materially below ~86.25%, a fiscal Q2 margin guide below Q1, or a quarter of falling DRAM or NAND prices FQ1-27 report Management named fiscal Q1 as the margin floor. A lower print or guide means the peak is in.

The Story Right Now (as of 2026-09-30)

Micron is doing well and still accelerating. The September 30 report was its sixth consecutive record quarter, and once the extra week is stripped out, the December-quarter guide holds the same weekly growth pace.

Data as of 2026-09-30 close: MU $1,065.11, RSI 59.7, +5.2% vs SMA20, +58.2% vs its 200-day, 15.13% below its 52-week high, +536.57% over one year. That is an intact long uptrend, extended, sitting in a 6.4-week base.

The print cleared its own bar on every guided line except spending. Fiscal Q4 revenue was $54.23 billion against a guide of $50.0 billion ± $1.0 billion. Non-GAAP gross margin was 87.0% against about 86%. Non-GAAP diluted EPS was $33.42 against $31.00 ± $1.00 (GAAP $32.87). The Bloomberg consensus, as reported in a post the desk captured, was $51.49 billion and $31.83. DRAM revenue rose 27% sequentially on high-teens price increases and mid-single-digit bit growth. NAND rose 42% on prices up about 30% and bits up about 10%. Non-GAAP operating expenses of $2.57 billion ran well above the ~$1.65 billion guide. Management attributes that to a fiscal 2026 bonus increase for every employee and a $300 million community-investment contribution. The 31% sequential revenue gain includes a 14th week; per week, revenue rose about 21.5%.

The guide carries the run into fiscal 2027. Fiscal Q1 revenue is guided to $61.5 billion ± $1.5 billion. Non-GAAP gross margin is guided to about 86.25% (GAAP about 85.95%) and non-GAAP EPS to $38.15 ± $1.00 (GAAP $37.84) on about 1.15 billion shares. Against a 13-week quarter, the midpoint is about 22% more revenue per week than fiscal Q4. Management expects higher gross margins after fiscal Q1 "with a more moderate rate of price increases." It projects about $2.5 billion more operating expense in fiscal 2027 and a tax rate near 15.5%. Captured post-print posts put the Street's fiscal Q1 revenue estimate near $57 billion and its margin estimate at 86.4–86.7%. Revenue guidance landed well above that; the margin guide landed slightly below it.

Contracts change the durability question. Micron has signed 26 Strategic Customer Agreements. These are multi-year take-or-pay contracts that the company estimates cover over 35% of its revenue through 2030. Three-quarters of that revenue has a defined pricing framework, mostly bands with floors and ceilings. The rest reprices periodically at market. Customer commitments rose to $32 billion, "the vast majority of which are cash deposits." Remaining performance obligations are about $150 billion. That figure counts only priced agreements at committed volumes and minimum prices. The CFO repeated that "even at floor prices, we expect margins meaningfully above any prior cycle peak margins." That is an expectation, not a contract term. The $12.3 billion of deposits received in the quarter sits in financing cash flow, so it does not inflate free cash flow.

The objection is margin at a peak while supply planning turns up. Micron will spend more than planned. It guided fiscal Q1 capex to about $11.5 billion and first-half capex to about $25 billion, against $27.37 billion of net capex for all of fiscal 2026. Management says most of the increase is construction for cleanroom space in late calendar 2028 and beyond, while some equipment spending is being pulled forward to fill existing cleanrooms. Scarcity is already rationing demand. Management expects high-teens server unit growth with "a modestly lower rate of content growth than prior expectations, amid tight memory supply." It also flags possible double-digit unit declines in PCs and smartphones. New fabs start output between mid-2027 and 2030, and management says each becomes meaningful only "a few quarters after initial output." On that schedule, calendar 2028–2029 is when this cycle gets tested.

The call is wait, then buy the breakout. The October 1 session decides the reaction. A Yahoo Finance after-hours quote sat about 0.8% below the close at 5:43 p.m. ET and was flat by 7:29 p.m. ET. Both are context only. A settled close above the base pivot starts a position. A settled close below the support shelf voids it. A fiscal Q1 margin materially under the guided floor, or any quarter of falling contract prices, breaks the thesis.

The call Q&A, read from a third-party transcript, brought no new guidance. Management put the fiscal Q1 margin dip at about $1 billion of higher cost. It clarified that the more than 75% of 2027 output already committed spans all customers, not only the take-or-pay agreements. It gave no totals for fiscal 2027 buybacks or capex (all per the call).
