Micron reported fiscal fourth-quarter results after the close on Wednesday, September 30, and beat on nearly every number that mattered: revenue, earnings per share, and forward guidance all came in above Wall Street’s consensus. The options market had priced roughly a 10% move into the report. What actually happened: the stock closed September 30 at $1,068.95 and traded near $1,065 the next day, a move of well under 1%. The headline here isn’t the beat. It’s how little the stock moved despite one of Micron’s biggest quarters on record, a real-world example of exactly the expected-move-versus-realized-move gap this setup was built to explain.
- Micron reported fiscal Q4 2026 revenue of $54.23 billion and non-GAAP EPS of $33.42, both well above Wall Street consensus (~$50.6B / $31.27) and above the high end of the company’s own June guidance, per Micron’s own SEC filing (Form 8-K, press release dated September 30, 2026).
- Despite the double beat, MU’s stock barely moved: it closed September 30 at $1,068.95 and traded around $1,065 on October 1, a realized move under 1%, far inside the roughly 10% move the options market had priced in going into the report.
- Micron guided fiscal Q1 2027 revenue to $61.5 billion ± $1.5 billion and non-GAAP EPS to $38.15 ± $1.00, both again above the prior Wall Street consensus, yet the market treated the outlook as already priced in.
- This continues the pattern flagged before the print: Micron’s last several quarters have beaten estimates almost every time, and the stock’s reaction has still ranged from muted to a double-digit move, with no reliable link between the size of the beat and the size of the reaction.
- This is a recap of what happened, not a trade recommendation. Every example below is hypothetical and illustrative.
What Micron Actually Reported
Fiscal Q4 2026 revenue came in at $54.23 billion, up 31% sequentially and roughly 379% year over year, beating the Wall Street consensus of approximately $50.6 billion and clearing the high end of Micron’s own June guidance range ($50.0 billion ± $1.0 billion) by more than $3 billion. Non-GAAP EPS of $33.42 came in well above the $31.27 consensus estimate and above the high end of the company’s own $31.00 ± $1.00 guidance. Non-GAAP gross margin reached 87.0% of revenue.
For the full fiscal year 2026, Micron reported revenue of $133.19 billion (up 256% year over year) and non-GAAP EPS of $75.52, an 811% year-over-year increase, reflecting just how much smaller Micron’s AI-memory-driven business was in fiscal 2025 by comparison. All figures are sourced directly from Micron’s own September 30, 2026 press release filed with the SEC (Form 8-K), not secondary estimates.
| Metric | Q4 FY2026 Actual | Pre-Report Consensus |
|---|---|---|
| Revenue | $54.23B | ~$50.6B |
| Non-GAAP EPS | $33.42 | $31.27 |
| Non-GAAP gross margin | 87.0% | n/a |
| Q1 FY2027 revenue guidance | $61.5B ± $1.5B | ~$56.6B (prior estimate) |
The Real Story: A Record Beat, a Flat Stock
Going into the report, the at-the-money straddle for the first post-earnings weekly expiration was pricing an expected move of roughly 10.3%, or about $104 on a stock trading near $1,015 as of the pricing snapshot taken in the week before the print. By the close on September 30 (report day), MU had already drifted up to $1,068.95. In initial after-hours trading immediately following the release, shares briefly popped as much as 1.6%, but the move faded through the session, and by October 1 the stock was trading around $1,065, a realized move of well under 1% from the pre-report close.
That’s a striking gap. Micron beat revenue consensus by roughly $3.6 billion, beat EPS consensus by more than $2 per share, and guided the next quarter above where Wall Street already stood, and the stock essentially shrugged. Coverage at the time attributed the muted reaction to investor focus on rising capital expenditures and a slower near-term pace of free cash flow conversion, concerns that sat alongside the headline beat rather than being resolved by it.
This is the exact pattern flagged before the print: Micron’s reaction to a beat has not been consistent. The prior quarter (Q3 FY2026, reported June 2026) sent the stock up more than 13% the next session on a smaller beat. This quarter’s larger beat produced almost no move at all. The lesson isn’t that one reaction was “right” and the other “wrong”; it’s that the size of a beat and the size of the stock’s reaction are not reliably linked on this name, and anyone who assumed a bigger beat guarantees a bigger pop would have been wrong this time.
What This Means If You Had a Position Into the Print
For context on how the pre-earnings strategy frameworks would have fared: a hypothetical iron condor with short strikes placed near $910 (put side) and $1,120 (call side), the structure outlined before the report as a bet that the move would stay inside the implied range, would have been a comfortable winner, since the stock’s actual move stayed nowhere near either short strike. A hypothetical debit spread making a directional bet either way would likely have lost most of its premium to time decay and the post-earnings IV crush, since the stock simply didn’t move enough to clear a reasonable spread width. A calendar spread isolating the IV collapse itself would have benefited from exactly the dynamic it was designed for: front-week implied volatility collapsing once the event risk resolved, with the underlying barely moving.
None of this is a suggestion that condors are “the right trade” for every Micron earnings report. The prior quarter’s 13% move would have blown through the same condor’s short strikes. The point, consistent with the setup piece this recap updates, is that the options market’s priced move is a starting estimate, not a reliable ceiling or floor, and the only way to know which structure would have worked is after the fact.
Looking Ahead: The Fiscal Q1 2027 Guidance
Micron’s forward guidance was arguably more aggressive than the quarter it just reported: $61.5 billion ± $1.5 billion in revenue and non-GAAP EPS of $38.15 ± $1.00, both above the Street’s prior estimates heading into the print. That the stock didn’t rally on an above-consensus beat plus an above-consensus guide suggests the market had already largely priced in continued AI-memory strength, consistent with how far MU has run over the past year. The next real test is whether Micron actually delivers against this new, higher bar when it reports fiscal Q1 2027 results, likely in December 2026.
Bottom Line
Micron’s fiscal Q4 2026 report was a genuine beat on every headline number, yet the stock moved less than 1% against a priced expected move of roughly 10%. That gap, not the beat itself, is the most useful takeaway for anyone who trades earnings setups on this stock: a double beat with strong guidance is not the same as a guaranteed stock reaction, and position sizing that assumes the priced move will materialize can leave a trader overconfident in either direction.
FAQ
Q: Did Micron beat earnings estimates in fiscal Q4 2026?
A: Yes. Micron reported revenue of $54.23 billion and non-GAAP EPS of $33.42, both above Wall Street consensus (~$50.6 billion / $31.27) and above the high end of the company’s own guidance, per Micron’s September 30, 2026 SEC filing.
Q: How much did Micron’s stock move after the Q4 FY2026 earnings report?
A: Very little. MU closed at $1,068.95 on report day (September 30) and traded around $1,065 the next day, a move of well under 1%, far inside the roughly 10% move the options market had priced in beforehand.
Q: Why didn’t the stock move more on such a large beat?
A: Contemporary coverage attributed the muted reaction to investor focus on rising capital expenditures and a slower near-term pace of free cash flow conversion, concerns that offset the headline beat. It’s also consistent with a stock that had already run up sharply into the print, leaving less room for a positive surprise to move it further.
Q: What did Micron guide for fiscal Q1 2027?
A: Revenue of $61.5 billion ± $1.5 billion and non-GAAP EPS of $38.15 ± $1.00, both above the Wall Street consensus that existed heading into the Q4 report.
Q: Does this mean Micron earnings moves are unpredictable?
A: It means the size of a beat hasn’t reliably predicted the size of the stock’s reaction across Micron’s recent quarters. The prior quarter’s smaller beat produced a 13%+ gain; this quarter’s larger beat produced almost no move. Position sizing that assumes a specific outcome either way carries real risk.
