Most important: HBM4 qualification and customer expansionIn the print: Gross margin vs 81% guide, HBM revenue mixOn the call: DDR5 pricing trajectory, CY2027 supply outlookRisk: Guided beat masks peaking HBM pricing as Samsung ramps
House view
Street anchors on guided midpoints ($33.5B rev, $19.15 EPS) and treats a modest beat as routine. The print is secondary. What moves the stock is whether HBM4 qualification timelines and DDR5 pricing commentary confirm the supply deficit extends into CY2027.
What is priced in
Consensus sits on guided midpoints ($33.84B rev, $19.30 EPS), so a 3-5% beat is baked in given Micron's pattern of conservative guidance. NOT priced in: any upward revision to the $100B HBM TAM by 2028 forecast, evidence DDR5 contract pricing is accelerating beyond the 5-15% monthly range, or gross margin above the guided ~81% (up from 74.4% in Q2).
What decides the quarterRanked by thesis impact
Priority 1 · thesis-defining
HBM4 qualification and customer expansion
Micron sampled HBM4 16-Hi last quarter and ships HBM to 4 customers. Expanding beyond 4 or announcing HBM4 qualification confirms share gains in a market Micron projects at $100B by 2028. SK Hynix recently signaled HBM3E revenue beating expectations, raising the bar for Micron to show competitive parity.
✓HBM4 qualified with at least one customer, or customer count expands beyond 4, with quarterly HBM revenue disclosed above $4B.
✗HBM4 still in sampling with no qualification date, customer count flat at 4, or yield issues flagged on the internal logic base die.
Priority 2
Gross margin expansion toward 81% guide
Q2 gross margin was 74.4%. Hitting the guided ~81% requires HBM mix enrichment and DDR5 pricing gains. This is the clearest signal of whether the DRAM tightening thesis is flowing through to unit economics.
✓Non-GAAP gross margin at or above 81%, with management guiding Q4 flat or higher.
✗Gross margin below 79%, suggesting HBM mix or DDR5 pricing gains are stalling despite the tightening narrative.
Priority 3
DDR5 contract pricing momentum
DRAM spot prices have posted cumulative increases, but contract pricing lags. Data center DRAM and NAND exceeding 50% of industry TAM for the first time in CY2026 should sustain pricing power if the structural deficit holds.

Revenue
Guided $33.5B ± $750M; consensus $33.84B
Check total revenue vs $33.84B consensus and look for segment breakdown between DRAM and NAND in the press release tables.
Non-GAAP Gross Margin
Guided ~81%; Q2 was 74.4%
Find non-GAAP gross margin in the reconciliation table. Compare to the 81% guide and 74.4% prior quarter.
Non-GAAP Diluted EPS
Guided $19.15 ± $0.40; consensus $19.30
Check non-GAAP diluted EPS in the earnings table against the $19.15 midpoint and $19.30 consensus.
HBM Revenue Disclosure
FY2025 HBM + DC DRAM combined was $10B; no standalone Q2 HBM figure disclosed
Scan for any HBM-specific revenue figure, run-rate, or percentage-of-revenue disclosure in the press release or prepared remarks.
Adjusted Free Cash Flow
Q2 was $6.9B on $5.0B net capex
Check operating cash flow and net capex in the cash flow statement. Compute adjusted FCF and compare to Q2's $6.9B.
Flat to down. Top-line strength offset by margin compression and weakening forward outlook suggests the cycle is peaking.

✓Management cites double-digit sequential contract price increases for DDR5 and guides continued tightening into Q4.
✗Contract price increases decelerating to low single digits, or management flags CXMT commodity DRAM supply as a headwind to pricing.
Look for Q4 revenue, gross margin, and EPS guidance ranges. Compare to Q3 guided levels to assess sequential trajectory.
On the call · where thesis moves
CXMT competitive impact on commodity DRAM pricing
If management downplays CXMT's Shanghai megafab ramp, the DDR5 tightening thesis holds. Explicit concern signals commodity DRAM oversupply bleeding into ASPs.
1-gamma DRAM node production ramp and EUV tool availability
1-gamma provides 30% bit density improvement. Any EUV tool supply constraints would limit Micron's ability to convert tightening demand into volume.
HBM TAM forecast update vs prior $100B by 2028
An upward revision from the $100B by 2028 figure would be a fresh catalyst. Holding the number flat suggests the demand outlook is already captured.
Capex trajectory and fab investment plans for CY2027
Q2 net capex was $5.0B. Rising capex guidance signals confidence in sustained demand but compresses FCF. Flat or lower capex suggests caution.
Data center mix as percentage of total revenue
Management guided DC bits TAM exceeding 50% of industry for the first time in CY2026. Micron's own DC mix trending above 50% confirms structural demand shift.
