Shares of Micron Technology bounced 3% in pre-market Monday to $746.56, clawing back ground after a sharp 6.6% drop to $724.66 on Friday — a slide that came just days after MU hit an all-time high of $818.67 . The rebound signals investors are choosing to look past a wave of insider selling and instead refocus on the company's extraordinary AI-driven fundamentals. The tension between those two narratives will define MU's next chapter.
Insiders Cashed Out $52 Million, but Under Pre-Set Plans
Company insiders sold roughly $52.4 million in Micron stock over the past three months, led by CEO Sanjay Mehrotra's sale of 40,000 shares on May 1 at an average price of $536.26 — totaling $21.5 million.
EVPs April Arnzen and Sumit Sadana also sold, with one transaction totaling $10.1 million. Most sales were executed under pre-arranged Rule 10b5-1 trading plans — automatic schedules set months in advance to avoid insider-trading concerns. Still, the $52 million in insider sales suggests at least some insiders are not entirely sure the stock's meteoric rise is sustainable.
The Numbers Make the Bear Case Hard to Sustain
In Q2 FY2026, Micron posted $23.86 billion in revenue — up 196% year over year — with non-GAAP EPS of $12.20 against an $8.79 consensus estimate.
Gross margins have climbed from approximately 22% in fiscal 2024 to well over 50%. That kind of earnings power explains why the stock has run from a 52-week low of $90.93 to nearly $820 in twelve months, lifting its market cap to around $817 billion.
Sold-Out AI Memory Gives Micron Rare Pricing Power
Micron's entire 2026 high-bandwidth memory output is already committed under long-term contracts.
AI demand for memory could surpass 50% of the industry's total market this year, and analysts say the supply crunch is unlikely to ease before 2028.
Micron itself forecasts the HBM market growing at roughly 40% annually, from $35 billion in 2025 to $100 billion by 2028 — two years earlier than its prior outlook.
The Cycle Risk Hasn't Disappeared
Memory has always reverted; when pricing peaks, capacity expansions follow within twelve to eighteen months.
Micron's massive multi-year capital projects could weigh on free cash flow if AI spending or memory pricing falls short, and rising supply from rivals Samsung and SK Hynix could eventually pressure margins. At a P/E of ~34x, notably higher than its historical median , the stock is priced for perfection — leaving little room for stumbles.
