Micron Technology (NASDAQ: MU) heads into Wednesday’s earnings with numbers that would have seemed absurd a year ago. The company generated $25.4 billion of operating cash flow in Q3, while gross margin hit 84.9%, and management is guiding for another $50 billion of revenue and roughly 86% gross margin in Q4. Wall Street already expects about $50.86 billion of revenue and $31.45 in adjusted EPS, putting the bar close to management’s own guide before the report even lands.
The bigger story, though, is that Micron has spent 2026 turning a memory shortage into an enormous cash-generating machine, and now billions of those dollars are heading straight back into fabs, HBM, packaging, and new memory capacity.
What Happened In Q3?
Micron’s Q3 revenue explosion came overwhelmingly from what it could charge for each bit. DRAM revenue jumped 67% sequentially to $31.3 billion while bit shipments grew only in the low-single digits and average selling prices rose in the low-60% range. NAND revenue nearly doubled sequentially to $9.9 billion as ASPs climbed in the mid-80% range while bit shipments increased only in the mid-single digits.
That pricing translated into extraordinary operating leverage. Micron produced $33.7 billion of operating income and $28.9 billion of net income from $41.5 billion of revenue in Q3, while operating cash flow reached $25.4 billion.
Management expects DRAM and NAND demand to remain significantly above supply beyond 2027, while new fabs take years to build and the industry faces constraints around construction, labor, energy and manufacturing complexity.
That creates the setup for the next phase of the cycle. Micron can use today’s extraordinary cash generation to expand capacity while demand for AI servers, HBM and high-capacity memory keeps pulling supply forward.
$100 Billion Of Commitments Meets A Massive Capex Program
Micron now has 16 strategic customer agreements typically running from 2026 through 2030, covering roughly 20% of its DRAM volume and one-third of NAND volume. Fourteen of those agreements carry minimum-price revenue commitments totaling approximately $100 billion, while Micron says the agreements could eventually cover half or more of company revenue.
Several years of committed demand are now sitting against a much larger investment program. Micron expects roughly $10 billion of capex in Q4 and around $27 billion for fiscal 2026, with quarterly FY2027 capex expected to run above the Q4 level.
That is where the classic memory-cycle risk comes back into the picture. Micron, Samsung Electronics (KRX: 005930) and SK hynix (NASDAQ: SKHY) are all responding to the same shortage, so eventually the industry will add enough capacity to pressure pricing if supply grows faster than demand.
Micron’s contracts provide some insulation from that outcome because customers are committing to supply ahead of the new capacity coming online. The company is also negotiating pricing structures that include floors and ceilings, while planned agreements with fixed or near-current price ceilings are expected to represent roughly 40% of revenue.
The question for the next couple of years is therefore less about whether Micron can sell the additional memory and more about what margins look like once the new supply starts arriving.
HBM And Server Memory Raise The Ceiling
Micron is also pushing its mix toward products where capacity and performance are becoming strategic requirements for AI infrastructure.
The company is ramping 1-gamma DRAM and G9 NAND, preparing next-generation nodes for volume production in the second half of 2027 and ramping 12-high HBM4 at twice the speed of its HBM3E ramp. More than $1 billion of HBM4 revenue has already shipped.
On September 15, Micron unveiled a 512GB DDR5 RDIMM capable of speeds up to 9,200 MT/s, with operating power up to 60% lower than four 128GB modules. Advanced Micro Devices (NASDAQ: AMD) and Intel (NASDAQ: INTC) are validating the module for next-generation servers, with volume production expected in the second half of 2027.
The economics here are different from simply selling more commodity DRAM. AI servers need more memory, faster memory and increasingly dense memory configurations, giving Micron more ways to grow revenue through product mix while the industry works through the broader supply shortage.
A Clean Line In The Sand
Micron closed September 25 at $1,082.28, with the 20-day moving average around $994, the 50-day around $942, and the 200-day around $661. The stock has reclaimed the $1,000 area and remains above all three averages, but the previous high around $1,220 is still overhead, and the descending trendline from that peak has not been decisively cleared.
For the earnings trade, $1,000 is the first level I’d keep on the screen because it sits close to the 20-day average. Around $942, the 50-day becomes the next major reference point. A strong report followed by a hold above those levels would keep the recent breakout structure intact, while a sharp rejection from the 1,100–1,220 area followed by a break back through the moving averages would put the recent run under much more pressure.
Wall Street is already looking for roughly $50.86 billion of revenue and $31.45 of adjusted EPS, so a modest beat alone may not be enough to reset the stock’s trajectory. The bigger reaction should come from what management says about DRAM pricing, HBM supply, FY2027 margins, and the return on the enormous capex program now being built.
Since MU has already shown what a severe memory shortage can do to its income statement. The next leg of the story would be whether those economics can survive the billions being spent to expand the supply behind them.
