Micron Drops 7% as AI Memory Sell-Off Deepens
NEW YORK, July 29 —
Micron Technology shares fell 7% in a single session as a sector-wide memory sell-off deepened, pulling SanDisk down 9% and Western Digital 8% alongside it. Reports have framed the sector's broader decline as the AI memory boom going bust, with Micron, SK Hynix, and SanDisk now roughly 30% off their highs and still falling per recent coverage. The timing is difficult: Micron just posted the largest quarterly earnings beat in a three-quarter streak, its trailing revenue grew 345.7% year-over-year, and its CEO was selling stock in June at prices 37% to 45% above today's level.
- EPS of $12.20 versus a $9.16 consensus — the third consecutive and largest quarterly beat, disclosed in the June 24, 2026 8-K filing.
- Trailing twelve-month revenue of $90.27 billion, up 345.7% year-over-year.
- $190.84 million in net insider selling over the trailing 90 days. Zero purchases recorded in the period.
The Blowout Quarter
The earnings progression tells a clear story: $3.03 versus a $2.86 estimate, then $4.78 versus $3.96, then $12.20 versus $9.16. Each beat was larger than the last. Trailing revenue of $90.27 billion on 345.7% year-over-year growth reflects a period when demand for HBM and data center DRAM overwhelmed everything the industry had modeled. A semiconductor company does not grow revenue 345% unless something structural shifted.
The stock, at $820.53, trades at 5.3 times forward earnings. The average analyst price target of $1,507.38 sits 84% above that. The gap is either an extraordinary mispricing or evidence that the consensus earnings model is priced to be wrong. See the full DCF model and price target →
The $190 Million Exit
Across the trailing 90 days, Micron insiders disclosed $190.84 million in net stock sales against zero purchases. The CEO acted in two rounds. On June 26, Sanjay Mehrotra sold in multiple tranches at prices ranging from approximately $1,128 to $1,192 per share. On July 24, he sold again across 42 separate open-market tranches at approximately $906 to $966 per share. Neither round was at anything close to the current $820.53.
The largest single transaction came from EVP and Chief People Officer April S. Arnzen, who sold 10,497 shares at $1,079.99 on July 1, 2026, totaling approximately $11.34 million. The pattern across multiple insiders, at prices ranging from 10% to 45% above current levels, over a compressed 90-day window, is consistent with executives who held a different view on the stock's near-term trajectory than the analyst consensus does.
The Cycle Versus the Multiple
The market's 5.3x forward P/E embeds a specific thesis: earnings are about to reverse sharply. Memory cycles are notoriously violent in both directions. The DRAM industry typically compresses multiples well before earnings actually turn, which is why record quarterly results can coexist with a sub-6x forward multiple. Investors watching Micron, SK Hynix, and SanDisk fall in tandem are not pricing in company-specific weakness; they are pricing in cycle timing.
The counterargument, reflected in the $1,507 analyst target, is that the AI infrastructure buildout is still early and that discounting Micron at 5.3x while it compounds earnings quarter-over-quarter with no visible demand crack is premature cycle-calling. Both views have evidence behind them. The insider selling introduces a third data point that fits neatly into neither narrative.
What Changes the Thesis
Micron's next earnings report is the decisive checkpoint. HBM pricing and the cadence of hyperscaler orders will either validate the market's cycle-peak concern or expose it. If pricing holds and demand commentary is firm, the gap between $820 and the $1,507 consensus target becomes structurally difficult to sustain. If HBM pricing weakens or order visibility shortens, the $190.84 million in distributions at $1,000-plus looks less like routine financial planning and more like informed exit timing.
Three escalating beats, 345.7% revenue growth, and a 5.3x forward multiple rarely coexist. The fundamental picture is genuinely strong by any historical standard. The $190.84 million in net insider selling with zero purchases, concentrated at prices well above where the stock trades now, is equally hard to dismiss. Neither fact resolves cleanly into a directional call.

Frequently Asked Questions
Why is Micron stock falling despite beating earnings?
Micron has beaten analyst EPS estimates for three straight quarters, with the most recent print at $12.20 versus a $9.16 consensus. The stock has nonetheless declined roughly 30% alongside sector peers, as investors are pricing in a potential memory cycle peak rather than extrapolating the current growth rate. The market assigns a 5.3x forward P/E, implying it expects earnings to fall sharply from current levels.
How much did Micron insiders sell recently?
Micron insiders disclosed $190.84 million in net stock sales over the trailing 90 days, with zero purchases recorded. CEO Sanjay Mehrotra sold in June at prices ranging from approximately $1,128 to $1,192 per share and again in July at approximately $906 to $966, both above the current $820.53. EVP April S. Arnzen completed the period's largest single transaction, selling 10,497 shares at $1,079.99 on July 1 for approximately $11.34 million.
What is Micron's revenue growth rate?
Micron's trailing twelve-month revenue reached $90.27 billion, representing 345.7% year-over-year growth. The company has delivered three consecutive quarters of accelerating EPS beats, with the most recent quarter reporting $12.20 per share versus a $9.16 analyst estimate, per the company's June 24, 2026 earnings disclosure.
Is Micron stock undervalued right now?
At 5.3 times forward earnings and $820.53 per share, Micron is priced for a significant earnings contraction. The average analyst price target of $1,507.38 implies roughly 84% upside if the AI memory cycle sustains. The key question is whether the HBM and DRAM demand driving 345.7% revenue growth holds, or whether the sector's 30% decline reflects a genuine cycle turn.
What is driving the AI memory sector sell-off?
Reports have framed the decline as investors concluding that the AI-driven memory demand surge is approaching a peak. Micron, SK Hynix, and SanDisk have all declined roughly 30%, a coordinated move that points to macro cycle concerns rather than company-specific issues. The next set of earnings reports and HBM pricing data will provide the clearest read on whether demand is decelerating or whether the sell-off is misreading the cycle.
Micron Technology shares have been caught in a sector-wide memory rout, with reports citing a 7% single-session drop as fears mount that the AI-driven memory boom may be peaking. The decline lands awkwardly against three consecutive quarters of blowout earnings beats — and just days after CEO Sanjay Mehrotra closed tens of millions in open-market stock sales.
