Micron Cash Flow Strengthens the Case for Buying Into Weakness

Micron Technology traded at $945.03 at 10:24 a.m. ET on Tuesday, October 13, 2026, down $44.01 or 4.45% from Monday’s close of $989.04. The stock had been down as much as 5.8% in the first minutes of the session, which made it one of the heaviest single weights on the S&P 500 at the open. Volume reached 10.02 million shares in the first hour against a three-month daily average of 32.3 million, a pace that projects well above normal turnover for the full day.

The premarket path showed sellers moving early and steadily. Micron was down 2.8% at 5:50 a.m. ET, 3% by 7 a.m. ET, 4.8% by 8:43 a.m. ET and 5.5% shortly after the open. Each print was lower than the last before buyers showed up near the lows and pulled the loss back toward 4.45%.

Tuesday’s decline extends a two-day slide. Micron fell roughly 4% on Monday, so the stock has dropped close to 9% across two sessions. At a $1.069 trillion market capitalization, Tuesday’s move alone erased $50 billion in value before 11 a.m. ET.

The scale of the run that preceded it matters. Micron is up 428.73% over the past 52 weeks, with a range from $186.25 to $1,255.00. At $945.03, the stock is 24.7% below that 52-week high. The two-day drop is not a collapse for a name that ran that far; it is the market pulling forward the risk that 2027 DRAM pricing will not look like 2026 DRAM pricing.

The fundamentals tell a different story from the tape. Micron reported fiscal fourth-quarter revenue of $54.23 billion on September 30, its sixth straight quarterly record, with non-GAAP earnings of $33.42 per share and an 87.0% gross margin. It guided fiscal first-quarter 2027 revenue to $61.5 billion and non-GAAP EPS to $38.15. Annualize that EPS guide and the stock trades at 6.2 times forward earnings. Against fiscal 2026 non-GAAP EPS of $75.52, it trades at 12.5 times trailing.

The thesis for this forecast is direct: the market is pricing Micron as a peak-cycle commodity producer about to face Chinese oversupply, while the company is guiding to another record quarter, holds $68.3 billion in net cash, has sold out its calendar-2026 HBM supply and has locked half its revenue into multi-year strategic customer agreements. The gap between those two pictures is where the opportunity sits. The near-term tape is broken, and $900 needs to hold. The medium-term setup favors buyers on weakness.

The CXMT 4F² Announcement: Why a Design Milestone Hit a $1 Trillion Stock

The trigger for the two-day selloff came out of China over the weekend. ChangXin Memory Technologies, the Shanghai-listed DRAM maker known as CXMT, said through its president Cao Kanyu that it has made key progress on a new 4F² DRAM cell structure. The architecture is engineered to pack more storage into less silicon area. CXMT plans to roll out a server memory product built on that design by the end of 2026.

The announcement hits Micron’s thesis at its foundation. The memory boom of 2026 has been built as much on supply discipline as on AI demand. Samsung, SK Hynix and Micron have controlled bit supply, held back capacity additions and pushed pricing higher quarter after quarter. Micron’s fiscal fourth-quarter DRAM average selling prices rose in the high-teens percentage range sequentially, and NAND prices climbed roughly 30%. That pricing power depends on scarcity. A credible new entrant in server-grade DRAM at a denser cell structure is a direct threat to it.

CXMT is not a fringe player. It is the world’s fourth-largest DRAM maker. Its share of global DRAM revenue rose to 8% in the first quarter of 2026 from 3% a year earlier, while Micron held 22%. That puts CXMT’s DRAM share at 36% of Micron’s. CXMT raised $8.6 billion in a public offering earlier this year and is planning an additional fab in Beijing.

The market has already reacted to CXMT several times this year. On July 15, Micron fell 8.02% to $904.28 the day after CXMT’s filing disclosed its IPO terms. On August 3, Micron dropped 3.5% to $794.59, with an intraday low of $771.30, on a report renewing concerns about Chinese supply after 2026. Each CXMT headline has produced a sharp one-day selloff in Micron followed by a recovery.

The difference this time is the target market. CXMT has long been viewed as one generation behind Samsung and SK Hynix and has not been a near-term competitor in high-bandwidth memory, which is where Micron’s highest margins sit. A 4F² server DRAM product moves CXMT closer to the data-center segment that has driven Micron’s growth.

The limiting factors are execution and timing. CXMT has said end of 2026 for the product launch; yields, qualification with hyperscale customers and volume ramp all sit beyond that. CXMT could fall short of yield targets or struggle to finance capacity on the timeline the market is now pricing. Micron’s contracted revenue covers the period in which that uncertainty resolves.

Seoul Breaks First: Samsung Down 7.39%, SK Hynix Down 8% to 10%, KOSPI Down 5.46%

Micron’s U.S. selloff followed a crash in Korea. South Korea’s KOSPI closed down 5.46% at 6,035.35 on Tuesday after falling more than 5% intraday and triggering a sell-sidecar, with an intraday low briefly below 6,000. Samsung Electronics fell in the 7% range, with a print of 7.39%, and SK Hynix dropped between 8% and 10%. Both stocks extended losing streaks to five sessions.

Samsung and SK Hynix together account for more than half of South Korea’s total market capitalization. A memory-specific shock becomes a national index event almost mechanically. Tokyo Electron, the chip-equipment maker, fell 7.2% in Japan. CXMT’s own shares fell 2.79% in Shanghai, which says the market sees the 4F² news as a threat to incumbents more than a windfall for the challenger.

SK Hynix’s U.S.-listed shares traded at $155.11 by mid-morning, down $7.12 or 4.39%, on 9.43 million shares. At a $1.103 trillion market capitalization, SK Hynix is slightly larger than Micron. Its 52-week range of $124.80 to $199.87 puts it 22% below its high, a slightly smaller drawdown than Micron’s 24.7%.

The storage complex took the hardest hits. Western Digital tumbled 7.71% in premarket trading after a price-target cut to $470 from $525. Seagate Technology sank 7.28% on the broader storage selloff and reports of a multibillion-dollar acquisition bidding war. SanDisk fell between 6% and 7% in premarket after dropping 6% on Monday.

Monday’s U.S. data shows how concentrated the selling was. The Philadelphia Semiconductor Index fell 2.7% on Monday, a DRAM-focused index dropped 4.32% and the broad semiconductor ETF lost 2.05%. AMD fell 2.28% and Broadcom 1.88%. Optical and networking hardware also got hit: Cerebras dropped 10.69%, Semtech fell 10.15%, Ciena lost 9.95% and Lumentum gave back 9.78%.

On Tuesday, the hit spread to semiconductor names well beyond memory. AMD fell 3.3% after the open and Marvell dropped 3% in premarket. Nvidia held near flat at $225.68, down 0.28%, and Intel slipped 1.07% to $100.27.

That split matters for Micron’s forecast. GPU makers, which buy memory, barely moved. Memory and storage makers, which sell it, got liquidated. The market is repricing a single profit pool: memory margins. A cheaper DRAM future is a lower input cost for Nvidia’s systems and a margin threat for Micron. The selloff is sector-specific, not a broad AI capitulation, which is why the S&P 500 was down only 0.12% at 7,798.11 while memory names dropped 4% to 8%.

Broadcom’s “Casino” Comment and a Taiwan Strike Threat Add to the Pressure

Two more headlines compounded the CXMT shock. On Monday, at an event in Singapore, Broadcom CEO Hock Tan said many AI investors have no clue what they are investing in and compared the speculative behavior to gambling in a casino. Coming from the chief executive of one of the largest custom AI accelerator suppliers, the comment hit sentiment across the AI hardware chain. Broadcom fell 1.88% on Monday and dipped another 1% in premarket Tuesday.

The second headline was the threat of a potential labor strike in Taiwan, which was cited alongside the CXMT news as weighing on Micron in premarket trading. Micron operates significant DRAM manufacturing in Taiwan. A strike would affect supply rather than price, and in a supply-constrained market that could cut both ways: lost output for Micron, but tighter industry supply that supports pricing.

Tan’s comment lands on an AI trade already losing altitude. After two quarters of large upside surprises that pushed the indices to records, earnings beats have become the baseline. The question now is whether AI capital spending can grow again in 2027 and whether it gets monetized. A CEO calling the speculative fringe a casino challenges the multiple investors are paying for that durability.

For Micron, the AI spending question is the central variable. Micron’s Core Data Center Business Unit generated $18.0 billion in fiscal fourth-quarter revenue, up from $1.58 billion a year earlier, an 11-fold increase. Its Cloud Memory Business Unit, which includes HBM, generated $16.3 billion. Together, the two data-center segments produced $34.3 billion, or 63% of total revenue. Any slowdown in hyperscaler AI capex would hit those segments first.

The AI infrastructure lane was under pressure across the board Tuesday. CoreWeave fell 2.97% to $77.88, down 40.13% over 52 weeks. Applied Digital dropped 5.61% to $21.94. Cipher Digital collapsed 15.81% to $10.94. The IMF flagged an AI slowdown and spiking bond yields as looming risks to global markets.

The rate backdrop amplifies every AI concern. The 10-year Treasury yield traded at 5.22% Tuesday, after touching its highest level since 2002 last week. The Fed hiked in September and fed funds futures price an 88% chance of another hike by December. High rates raise the cost of capital for the AI data-center buildout that drives memory demand, and they compress the multiples investors will pay for cyclical earnings.

Micron’s management addressed the AI durability question directly. CEO Sanjay Mehrotra said on September 30 that AI is becoming super intelligence and that Micron’s strategic customer agreements provide added confidence in the durability of its financial performance. The market is testing that confidence this week.

Fiscal Q4 2026: $54.23 Billion in Revenue, 87% Gross Margin, $33.42 EPS

Micron’s most recent quarter was the strongest in its history by every measure. Fiscal fourth-quarter revenue for the period ended September 3, 2026, came in at $54.23 billion, up 31% from $41.46 billion in the third quarter and up 379% from $11.32 billion a year earlier. It was the sixth consecutive quarterly revenue record. Revenue, gross margin and EPS all exceeded the high end of the company’s own guidance.

Profitability reached levels unprecedented for a memory company. GAAP gross margin was 86.8% and non-GAAP gross margin was 87.0%, up 210 basis points sequentially. GAAP operating income was $43.75 billion, an 80.7% operating margin. GAAP net income came in at $37.70 billion, or $32.87 per diluted share. Non-GAAP net income was $38.40 billion, or $33.42 per share. A year earlier, Micron earned $3.20 billion, or $2.83 per share.

The product split shows the AI tilt. DRAM revenue hit a record $39.8 billion, up 343% year over year and 27% sequentially, representing 73% of total revenue. DRAM bit shipments rose in the mid-single digits sequentially and prices climbed in the high teens. NAND revenue reached $14.1 billion, 26% of the total, with bit shipments up roughly 10% and prices up roughly 30%. Data-center SSD revenue reached nearly $10 billion, more than 10 times the year-ago level and over two-thirds of total NAND revenue.

The business-unit breakdown confirms the margin profile is broad. The Core Data Center Business Unit generated $18.0 billion at a 90% gross margin and an 85% operating margin. The Cloud Memory Business Unit generated $16.3 billion, up 18% sequentially, at an 83% gross margin, flat sequentially as a higher HBM mix offset pricing gains. The Mobile and Client Business Unit produced a record $13.1 billion at a 90% gross margin. The Automotive and Embedded Business Unit produced $6.8 billion at an 84% gross margin.

Cash generation was enormous. Operating cash flow reached $43.97 billion in the quarter, 81% of revenue, up from $25.39 billion in the third quarter. Net capital expenditures were $10.77 billion, leaving adjusted free cash flow of $33.20 billion for the quarter.

The quarter included a $500 million patent license charge, excluded from non-GAAP results. Operating expenses rose to $3.30 billion on a GAAP basis from $1.74 billion in the third quarter, reflecting that charge plus higher R&D spending of $1.91 billion.

The shares slipped in after-hours trading on September 30 despite the beat, as investors weighed heavy spending plans against the strong outlook. That reaction set the tone for the following two weeks: Micron’s numbers have stopped moving the stock higher, because the market is focused on how long the cycle lasts rather than how strong it is today.

Fiscal 2026 in Full: $133.19 Billion in Revenue and $75.52 in EPS

The full fiscal year shows the magnitude of the cycle. Micron’s fiscal 2026 revenue reached $133.19 billion, up 256% from $37.38 billion in fiscal 2025, 3.5 times the previous annual record. GAAP net income was $84.97 billion, or $74.33 per diluted share. Non-GAAP net income was $86.76 billion, or $75.52 per share, up 811% year over year from $8.29.

GAAP gross margin for the year was 80.7%, against 39.8% in fiscal 2025. GAAP operating income was $99.34 billion, a 74.6% operating margin, against $9.77 billion and 26.1% a year earlier.

Cash flow reshaped the balance sheet. Fiscal 2026 operating cash flow was $89.68 billion, 67% of revenue, against $17.53 billion in fiscal 2025. Net capital expenditures totaled $27.37 billion, leaving adjusted free cash flow of $62.31 billion for the year, compared with $3.72 billion in fiscal 2025.

The balance sheet now carries a fortress of cash. Micron ended the year with $73.48 billion in cash, marketable investments and restricted cash, up from $30.2 billion at the end of the third quarter. Cash and equivalents alone were $38.36 billion, with $5.07 billion in short-term investments and $30.02 billion in long-term marketable investments. Total debt fell to $5.18 billion, with $491 million current and $4.69 billion long-term, after Micron repaid $10.04 billion of debt during the year. That leaves net cash of $68.3 billion, 6.4% of the current market value.

The cash-flow statement also shows the structural change in Micron’s business. Micron received $12.75 billion in customer contract liability deposits during fiscal 2026, and noncurrent customer contract liabilities rose to $12.90 billion from $142 million a year earlier. Those are prepayments from customers locking in supply under strategic agreements. Customers are paying Micron in advance to secure memory, which is the opposite of a commodity cycle where buyers hold the leverage.

Total equity rose to $138.38 billion from $54.17 billion. Retained earnings climbed to $131.85 billion. Total assets reached $195.89 billion, up from $82.80 billion.

Capital returns remain modest relative to cash generation. Micron repurchased $650 million of stock under its buyback program in fiscal 2026 and paid $610 million in dividends. The board declared a quarterly dividend of $0.15 per share, payable October 29 to shareholders of record as of the close on October 14, which is Wednesday. Management has said it expects to boost capital returns after December 9, 2026. At $62.31 billion in annual free cash flow, the current return program barely registers.
