Micron (MU) Posts Record $54.2B Q4 Revenue, Crushes EPS Estimates - Stock Barely Moves on $25 Billion Capex Guidance
In this article
What Happened
After the closing bell on Wednesday, September 30, Micron Technology reported fiscal fourth-quarter 2026 results that beat Wall Street's expectations by a wide margin. Adjusted earnings per share came in at $33.42, well above the $31.61 analysts had forecast, while revenue hit $54.23 billion against a consensus estimate of $51.07 billion. That revenue figure was nearly four times the $11.32 billion Micron posted in the same quarter a year earlier, underscoring just how much AI-driven data center memory demand has reshaped the company's business. Guidance for the first quarter of fiscal 2027 was equally strong: Micron pointed to roughly $61.5 billion in revenue and adjusted EPS of $38.15, both ahead of the $57 billion and $35.40 Wall Street had penciled in.
Despite a quarter that checked every box, the stock's reaction was muted. Shares closed the regular session at $1,074.95, up only about 0.1% on the day, then slipped roughly 0.3% to 1% in after-hours trading following the report - a sharp contrast to June's third-quarter release, when the stock jumped 14.6% in a single after-hours session on similarly strong numbers. This time, investors fixated less on what Micron had already earned and more on what it plans to spend. The company said it would sharply raise capital expenditures in fiscal 2027, guiding to roughly $11.5 billion in the first quarter alone and about $25 billion for the first half of the fiscal year, with spending expected to climb even higher in the back half. Management tied the ramp to the need for additional DRAM clean-room capacity as it anticipates memory supply staying tight through 2027 and into 2028.
The other notable thread in the report was high-bandwidth memory, or HBM. Micron said HBM revenue grew faster than the company's overall revenue during the quarter, and that it has already locked in contracts covering the "vast majority" of its calendar-2027 HBM bit supply at meaningfully higher prices than a year earlier - a dynamic that narrows the margin gap between HBM and conventional DRAM. Micron remains the smallest of the three major HBM suppliers behind Samsung and SK Hynix, however. Wall Street's price-target reaction was unambiguously bullish even as the stock itself stalled: Citi raised its target from $1,150 to $1,300, Baird lifted its target from $1,280 to $1,520, and JPMorgan held its Overweight rating and $1,540 target. Micron shares have climbed more than 500% over the past year, pushing the company's market capitalization above $1.2 trillion.
Why a Record Quarter Didn't Move the Stock
This episode is a clean illustration of why a beat-and-raise quarter and a rising stock price aren't the same thing. Earnings and near-term guidance are, by nature, backward- or near-term-looking: they tell you what already happened or what's about to happen next quarter. What investors price into a stock, by contrast, is a longer-run view of free cash flow - how much cash the business will actually generate and keep. Micron's plan to spend roughly $25 billion on capex in just the first half of fiscal 2027 means a large chunk of the operating cash flow it just reported will be plowed straight back into new fabs and equipment rather than returned to shareholders through buybacks or dividends. Record revenue and earnings matter less to a stock's near-term trajectory when the market is simultaneously digesting how much of that cash is about to be reinvested rather than distributed.
Memory chips are a particularly capex-sensitive corner of the semiconductor industry precisely because they're a commodity product whose prices swing hard with supply and demand. The industry has lived through this movie before: a wave of aggressive capacity expansion in 2017-2018, driven by a memory boom, was followed by a supply glut and a sharp price collapse in 2019 that hammered memory stocks across the board. That history has left investors wary of exactly the kind of announcement Micron just made - today's aggressive investment can become tomorrow's oversupply problem, compressing the same margins that look so strong right now. That memory of past cycles is a big part of why the market greeted an otherwise excellent quarter with caution rather than enthusiasm.
Still, there's a reasonable case that this cycle doesn't map cleanly onto the 2017-2019 boom-bust pattern. The key difference is the nature of demand. The last memory supercycle was driven largely by generic consumer electronics - PCs and smartphones - while this one is anchored in AI data center buildouts and the HBM and high-capacity server DRAM they require. The fact that Micron has already locked in pricing and volume commitments covering the bulk of its 2027 HBM output means the capacity it's building has a buyer attached before it's even built, a meaningfully different risk profile than capacity built speculatively ahead of uncertain demand. One analyst on the earnings call put it directly, saying they hadn't "heard any negative data points pointing to the memory cycle reversing toward a decline anytime soon." Read that way, the stock's flat reaction looks less like skepticism about Micron's business and more like the market weighing a multi-year capital allocation story against a single quarter's headline numbers.
What to Take Away From This
- A beat-and-raise quarter doesn't guarantee a stock pops. Even when both revenue and EPS clear estimates by a wide margin, the market can care more about next quarter's spending plans than this quarter's scorecard.
- Rising capex is a double-edged signal. Aggressive investment can reflect real confidence in future demand, but it also eats into near-term free cash flow and can revive memories of past oversupply cycles.
- Memory semiconductors are a textbook cyclical industry. Knowing the 2017-2019 boom-and-bust pattern makes it easier to read "record quarter" headlines with appropriate caution during the next upcycle.
- Analyst price-target hikes and same-day stock moves can diverge sharply. Citi, Baird, and JPMorgan all raised or held bullish targets the same day the stock barely budged - a reminder that long-term conviction and short-term price action are not the same signal.
FAQ
If Micron's results were record-breaking, why didn't the stock rise?
Both the quarter and the forward guidance beat Wall Street's estimates, but investors focused instead on Micron's plan to spend roughly $25 billion on capital expenditures in just the first half of fiscal 2027. Concerns about how much of that cash will be reinvested, rather than the strength of the quarter itself, appear to have capped the near-term stock reaction.
Why does HBM matter so much to Micron's story?
High-bandwidth memory is the specialized, higher-margin memory chip required by AI accelerators, and it carries notably better economics than conventional DRAM. Micron having already locked in pricing for most of its 2027 HBM supply is seen as a key indicator of future revenue quality and margin trajectory.
Is rising capital spending always bad news for a stock?
Not necessarily. Capex backed by firm demand commitments can fuel durable long-term growth. But in the near term it reduces free cash flow, and in a historically cyclical industry like memory, it can revive fears of the kind of supply glut that hit prices hard in 2019 - which is why markets often react cautiously even to well-telegraphed spending plans.
Can Micron stock keep climbing from here?
Price-target increases from Citi, Baird, and a maintained bullish stance from JPMorgan all point to continued analyst confidence in the long-term story. That said, with shares already up more than 500% over the past year, valuation and the capex cycle itself are worth watching closely for near-term volatility.
