Micron FY3Q26 Earnings: AI Memory Bottlenecks, 84.9% Gross Margin, And A $50B Guide

This note follows the Samsung-Hynix-Micron parity series, the AI chip and memory P/E map, the SK Hynix versus Micron comparison, and the recent memory-price-risk work around CXMT. The central question is no longer whether Micron is an AI-memory proxy. FY3Q26 showed that the proxy now has earnings, gross margin, FCF, and customer commitments behind it.

TL;DR

Micron’s FY3Q26 was not just an earnings beat. Revenue reached $41.456bn, non-GAAP EPS was $25.11, non-GAAP gross margin was 84.9%, and FY4Q26 guidance called for $50.0bn of revenue and $31.00 of non-GAAP EPS. These figures are from Micron’s official release.

The key change is threefold.

Micron can no longer be treated as a plain commodity-memory equity. Management framed memory bandwidth and capacity as structural bottlenecks for AI systems, and data-center revenue exceeded $25bn in the quarter.
The company has signed 16 strategic customer agreements, or SCAs. For 14 of those contracts, Micron pointed to roughly $100bn of minimum revenue at floor prices and about $22bn of customer deposits and financing commitments. Take-or-pay terms and price floors reduce, but do not eliminate, the earnings-collapse risk that normally defines memory cycles.
The stock already reacted. After the release, after-hours quotes showed a double-digit rally, roughly in the mid-teens depending on the data vendor. The numbers were excellent, but the margin of safety narrowed quickly.

My conclusion is HOLD, with new buying better left for pullbacks. The revised 12-month target is $1,350. Versus the roughly $1,214 after-hours reference price used in this note, that implies about 11% upside. The upside looks larger versus the regular close of $1,048.51, but that price did not fully include the earnings release.

Event Check

Item	Status	KST Timing	Evidence
Recent earnings release	Confirmed	2026-06-25 05:01	Micron released FY3Q26 results at 2026-06-24 16:01 ET. FY3Q26 ended 2026-05-28.
Earnings call	Confirmed	2026-06-25 05:30	Micron scheduled its Third Quarter 2026 Financial Call at 4:30 PM ET.
Prepared remarks and deck	Confirmed	After release	Micron posted the FY3Q26 presentation and prepared remarks on its IR site.
Post-earnings analyst call	Confirmed	2026-06-25 07:00	Reflected in the event schedule used for this review.

The FY3Q26 event is confirmed. FY4Q26 is not. Until Micron publishes the next date, late September after the US close is only an estimate.

FY3Q26 Numbers

Metric	FY3Q26	FY2Q26	FY3Q25	Interpretation
Revenue	$41.456bn	$23.860bn	$9.301bn	+73.7% QoQ, +345.7% YoY
GAAP net income / EPS	$28.243bn / $24.67	$13.785bn / $12.07	$1.885bn / $1.68	Extreme operating leverage
Non-GAAP net income / EPS	$28.857bn / $25.11	$14.021bn / $12.20	$2.181bn / $1.91	Non-GAAP EPS +105.8% QoQ and +1,214.7% YoY
GAAP gross margin	84.6%	74.4%	37.7%	Pricing, mix, and shortage effect
Non-GAAP gross margin	84.9%	74.9%	39.0%	+10.0pp QoQ and +45.9pp YoY
Non-GAAP operating income / margin	$33.681bn / 81.2%	$16.455bn / 69.0%	$2.490bn / 26.8%	More than 13 times the year-ago level
Operating cash flow	$25.39bn	$11.90bn	$4.61bn	Cash generation followed earnings
Capex, net	$7.084bn	$5.004bn	$2.660bn	Investment rising with demand
Adjusted free cash flow	$18.304bn	$6.899bn	$1.949bn	Record free cash flow
Cash, marketable investments, restricted cash	$30.2bn	not provided	not provided	Buffer for capex and capital return

The quality of the beat matters. GAAP EPS and non-GAAP EPS moved together. Operating income, operating cash flow, and adjusted FCF also moved together. This was not a one-line adjustment story.

Segment Data

Segment	FY3Q26 Revenue	FY2Q26 Revenue	FY3Q25 Revenue	FY3Q26 Gross Margin	FY3Q26 Operating Margin	Interpretation
Cloud Memory	$13.769bn	$7.749bn	$3.386bn	83%	78%	Core HBM and high-end DRAM growth engine
Core Data Center	$11.524bn	$5.687bn	$1.530bn	87%	83%	Data-center DRAM and SSD demand was very strong
Mobile and Client	$11.521bn	$7.711bn	$3.255bn	87%	86%	PC and mobile also benefited from pricing and mix
Automotive and Embedded	$4.634bn	$2.708bn	$1.127bn	79%	75%	Auto and embedded also participated

Cloud Memory plus Core Data Center reached about $25.3bn. That matches management’s comment that data-center revenue exceeded $25bn, or more than a $100bn annualized run-rate. This point is crucial: the quarter was not only about HBM. DRAM, NAND, SSD, client, mobile, auto, and embedded all showed pricing power.

FY4Q26 Guidance

Item	Company Guidance	Interpretation
Revenue	$50.0bn ± $1.0bn	$49bn to $51bn range
GAAP gross margin	About 86%	Record-level margin sustained
Non-GAAP gross margin	About 86%	Up again from 84.9% in FY3Q
GAAP EPS	$30.73 ± $1.00	Close to non-GAAP EPS
Non-GAAP EPS	$31.00 ± $1.00	$30 to $32 range
Non-GAAP operating expenses	About $1.65bn	Strong operating leverage
Diluted shares	About 1.15bn	EPS denominator

Reuters reported that the $50bn revenue guide was well above the LSEG consensus near $43.58bn. The guide says that FY3Q was not necessarily the peak. Still, management also noted that the rate of price increases can moderate, even if pricing remains favorable.

Consensus Beat

Item	Actual Or Guide	Consensus / Estimate	Difference	Reading
FY3Q revenue	$41.46bn	$35.69bn, Investing.com	+16.2%	Beat
FY3Q adjusted EPS	$25.11	$20.49, Investing.com	+22.6%	Beat
FY3Q revenue	$41.46bn	$35.91bn, MarketBeat	+$5.54bn	Beat
FY3Q EPS	$25.11	$20.98, MarketBeat	+$4.13	Beat
Non-GAAP gross margin	84.9%	81.6%, LSEG preview	+3.3pp	Beat
FY4Q revenue guide	$50.0bn ± $1.0bn	$43.58bn, LSEG via Reuters	Large beat	Beat and raise
FY4Q EPS guide	$31.00 ± $1.00	$25.84, Reuters preview	Above	Estimates need to move up

Consensus sources differ, but the conclusion is stable: Micron beat on revenue, EPS, gross margin, and the next-quarter guide.

The Strategic Customer Agreement Point

The most important non-earnings item was the SCA structure.

SCA Item	Management Detail	Investment Meaning
Number of agreements	16	Broad, not one-customer dependent
Typical duration	Mostly 2026 to 2030, with shorter automotive structures	Longer visibility than a normal memory cycle
Volume coverage	About 20% of DRAM volume and one-third of NAND volume	Already material
Potential revenue coverage	Could approach more than half of revenue once fully signed	Commodity discount can shrink
Pricing	Take-or-pay, floors, ceilings, some fixed or market-based pricing	Downside protection and some upside limits
RPO	More than $5bn at FY3Q end, with about $100bn for 14 signed SCAs expected in filings	Minimum revenue and floor-price framing
Deposits and commitments	Around $22bn, including about $18bn of cash deposits	Strong customer commitment

The SCA changes the debate. It gives Micron a floor under part of the cycle. It also proves that customers care enough about supply assurance to put money and obligations behind the contracts. But it is not a free option. Price ceilings can cap part of the upside when spot markets rise sharply, and customer deposits sit in financing cash flow rather than free cash flow.

What Management And Analysts Focused On

Topic	Core Message	Why It Matters
Supply tightness	DRAM and NAND demand is above industry supply, with tightness expected beyond 2027	The bull case is supply discipline and capacity bottlenecks
HBM4	High-volume shipments for a lead customer, more qualification samples, and more than $1bn of HBM4 revenue	HBM4 is already commercial, not just a future narrative
HBM4E	Development for calendar 2027 volume production	The next allocation battle is already starting
Deposits	Around $22bn of customer commitments, about $18bn in cash deposits	Customer behavior confirms scarcity
Capex	FY4Q capex around $10bn, FY2026 capex around $27bn, FY2027 quarterly capex above FY4Q	Growth needs capital and can pressure FCF later
Gross margin	86% guide, but price increases may moderate	The next issue is sustainability, not the absolute beat
Buybacks	Capital return remains centered on repurchases, but no precise cadence was committed	FCF conversion and buyback scale are the next equity catalysts

The call was not mainly about whether FY3Q beat. It was about how durable the new profit level is.

Upside And Downside Triggers

Upside Trigger	Timing	Mechanism
FY4Q revenue above $51bn or EPS above $32	FY4Q26 earnings	FY2027 run-rate estimates move up
More FY2027 HBM3E/HBM4 allocation fixed, faster HBM4E qualification	FY4Q call and second-half product updates	Longer shortage duration supports higher margins
SCA revenue coverage moves toward half or more of revenue	Next one to two quarters	Cyclicality discount shrinks
Large FY4Q FCF increase plus clearer buyback scale	FY4Q and 10-K	EPS accretion and FCF yield re-rating
Non-HBM DRAM and NAND pricing remains strong	ASP and segment margin updates	Reduces HBM concentration risk
Data-center revenue run-rate stays above $100bn	FY4Q and FY2027	Micron is reclassified as an AI infrastructure beneficiary

Downside Trigger	Timing	Mechanism
FY4Q revenue or EPS misses the midpoint of guidance	FY4Q26 earnings	Beat-and-raise thesis weakens
Gross margin rolls over from 86%	FY4Q and FY2027 guide	Memory supercycle multiple compresses
FY2027 capex consumes too much FCF	FY2026 10-K and FY2027 capex guide	FCF multiple and buyback hopes fall
SCA ceilings cap upside	Contract and margin commentary	Agreements look like caps, not floors
AI customers shift to cheaper memory structures	Accelerator product cycles	Premium DRAM and HBM pricing power weakens
Chinese memory makers penetrate higher-end products	Late 2026 to 2027	Supply and price competition return

Stock Reaction

FY3Q26 was released after the US close on 24 June 2026. Therefore the first regular session that fully reflects the news is 25 June 2026. At the original analysis time, that session had not opened.

Window	MU Price / Return	Interpretation
2026-06-24 regular session	$1,048.51, -0.31% using the supplied reference	Pre-release trading, not the event reaction
MarketBeat regular close	$1,037.93, -1.32%	Vendor difference
After-hours supplied reference	$1,213.97, +15.78%	Strong immediate reaction
MarketBeat after-hours	$1,221.62, +17.70%	Another vendor reference
1D regular session	Pending	Available after 25 June close
2D regular session	Pending	Available after 26 June close
5D regular session	Pending	Available next week

The reaction was driven by more than EPS. The FY4Q revenue guide, EPS guide, SCA commitments, long-duration supply tightness, and the FCF profile all mattered.

Valuation And Recommendation

Item	View
Rating	HOLD
New buying	Wait for pullback
12-month target	$1,350
Reference price	About $1,213.97 after hours
Upside	About +11.2%
Upside versus regular close	About +28.8%, but that price did not fully reflect the release

The valuation frame is forward P/E. FY2026 non-GAAP EPS can be approximated as Q1 $4.78 plus Q2 $12.20 plus Q3 $25.11 plus the FY4Q guide midpoint of $31.00, or $73.09. For the base case, I use FY2027 EPS of about $100. That is below the FY4Q26 run-rate to reflect FY2027 capex, start-up costs, and price normalization risk. The base multiple is 13.5 times.

Scenario	EPS Assumption	Multiple	Target Range	Key Condition
Bear	$70-80	11-12x	$800-950	Supply improves, ASP falls, capex and FCF pressure return
Base	About $100	13.5x	$1,350	FY4Q guide is achieved, HBM/SCA remain strong, FCF holds
Bull	$110-120	15x	$1,650-1,800	2027 supply sold-out extends, buybacks accelerate, SCA coverage rises

What Would Change The View

Change	Condition
Upgrade to BUY	Stock pulls back below $1,100, or FY4Q revenue exceeds $51bn and EPS exceeds $32 while FY2027 FCF visibility remains intact
Downgrade to SELL / reduce	Gross margin falls quickly below 80%, HBM4/HBM4E qualification is delayed, SCA additions disappoint, or customers shift toward cheaper memory architectures
Raise target	SCA-linked revenue approaches more than half of total revenue and FY2027 EPS visibility moves above $110
Lower target	FY2027 capex materially constrains cash return and the expected FY4Q FCF step-up does not materialize

Korean Semiconductor Read-Through

Korean Investor Question	Micron FY3Q26 Answer
Did Samsung Electronics and SK Hynix EPS risk rise?	No. Micron’s DRAM, NAND, HBM, and SSD numbers point to strong memory demand and pricing.
Is the Micron premium more justified now?	Partly yes. 84.9% non-GAAP gross margin, the 86% FY4Q guide, and SCA structures reduce the commodity-memory discount.
Does this hurt SK Hynix’s exclusivity premium?	It raises competitive pressure, but the HBM total addressable market is also expanding.
What does it mean for Samsung Electronics catch-up?	Samsung must prove HBM4E qualification, DS margin recovery, and customer allocation if it wants the discount to close.
What does it mean for Korean suppliers?	HBM, SSD, SOCAMM, high-capacity DDR5, test, packaging, and power-integrity demand remain supported.

The implication is not one-sided. Micron proved that the US-listed AI-memory premium has real earnings behind it. At the same time, if Korean memory EPS is not impaired, the relative discount of Samsung Electronics and SK Hynix versus Micron may remain too wide.

Next Quarter Checklist

Does FY4Q26 revenue reach the $50bn guide and EPS reach the $31 guide?
Do HBM3E and HBM4 remain fully booked through 2027?
Does HBM4E qualification stay on schedule?
How much revenue visibility do SCAs actually create?
Does the price floor protect margin downside more than the ceiling limits upside?
Can FY2027 capex rise while FCF and buybacks remain credible?
Does non-HBM DRAM and NAND pricing remain strong?
Do AI customers continue to demand more memory capacity and bandwidth, or do they shift toward cheaper memory architectures?
Do Chinese memory suppliers or large customers weaken Micron pricing power?

Sources And Limits

Core sources include Micron’s FY3Q26 official release, SEC Exhibit 99.1, the FY3Q26 presentation, prepared remarks, the Micron IR events page, Reuters coverage, MarketWatch live coverage, and the MarketBeat/Quartr transcript mirror. The Q&A transcript was treated as a web fallback and cross-checked against official materials where possible.

Regular-session 1D, 2D, and 5D event returns were not available at the analysis time because the release came after the US close. FY4Q26’s official date was also not yet confirmed. Data vendors showed different late-September estimates.

Portfolio-Manager Comment

This is not a normal memory rebound. It is pricing power attached to an AI infrastructure bottleneck. The numbers are excellent, but the market recognized that immediately. SCA makes Micron a better business than the old pure commodity-memory model, but memory remains memory: if supply returns too quickly, the stock can still be brutal. I prefer holding or buying on pullbacks rather than chasing the first after-hours reaction.
