The $700 Billion Memory Maker That Still Looks Cheap

Micron Technology hits $700B market cap as AI-driven HBM demand fuels record revenue, with forward P/E of 11 and 327% EPS growth expected.

When a stock nearly octuples in 12 months, most investors brace for a valuation reckoning. Micron Technology has defied that logic. The memory chip giant crossed a $700 billion market capitalization on Thursday, with shares touching an all-time high of $683. That marks a roughly 124 percent gain since January alone, and a staggering near-eightfold surge from a year ago.

Yet by traditional valuation metrics, the stock isn't screaming expensive. Micron trades at roughly 11 times forward earnings — a multiple that looks modest for a company riding the most powerful technology wave in decades. Even on a trailing basis, the price-to-earnings ratio sits around 31, close to the semiconductor sector average of 32. What justifies the disconnect is the earnings trajectory: analysts expect earnings per share to grow 327 percent.

The Structural Shift Behind the Numbers

This isn't a sentiment-driven rally. Micron reported second-quarter fiscal 2026 revenue of $23.9 billion, a 196 percent jump from the same period last year and the fourth consecutive quarterly revenue record. Management is guiding for $33.5 billion in the current quarter — roughly what the entire company generated in all of fiscal 2023.

The catalyst is artificial intelligence infrastructure, but the demand profile has evolved. Nvidia, AMD, and other chip designers need enormous quantities of high-bandwidth memory for their AI processors. Micron's entire HBM4 production for 2026 is already under binding contracts. More tellingly, customers are shifting from short-term order cycles to three-to-five-year supply agreements — a structural change that gives Micron unprecedented revenue visibility.

The addressable market for high-bandwidth memory is projected to grow from $35 billion to $100 billion by 2028, according to the company's own estimates. Mizuho analysts recently raised their price target to $740 with an "Outperform" rating, projecting Micron's HBM revenue alone could reach roughly $35.7 billion by that year. The broader HBM market is expanding at a compound annual growth rate of 40 percent.

The Political Insurance Policy

CEO Sanjay Mehrotra isn't leaving Micron's fate entirely to market forces. He has been meeting with members of the House Foreign Affairs Committee and Senate Republicans on the Banking Committee to push for the MATCH Act — legislation designed to close export loopholes for semiconductor manufacturing equipment and restrict Chinese memory rivals from accessing advanced production capacity. If passed, the bill would strengthen Micron's pricing power over the medium term by limiting competitive supply.

The Insider Signal That Isn't

The stock's meteoric rise has triggered insider selling, but the pattern doesn't necessarily signal alarm. Mehrotra sold 40,000 shares in early May at an average price of $536. Over the past 90 days, insiders have disposed of roughly 104,000 shares worth about $45 million. Such sales typically follow pre-arranged trading plans and often reflect portfolio diversification rather than bearish conviction.

Institutional behavior is split. Encompass More Asset Management slashed its position by nearly 60 percent, while Sigma Investment Counselors and Fire Capital Management have initiated new stakes.

The Split Question Resurfaces

With the stock trading well above $600, the conversation has turned to something Micron hasn't done since 2000: a stock split. The company last executed a split that year, followed by 24 years of lackluster performance that gave no reason to repeat the exercise.

A split would be purely cosmetic — converting a $700 share into ten $70 shares, for instance — but it can improve accessibility for retail investors and signal management confidence. Mehrotra is scheduled to speak at the J.P. Morgan Global Technology, Media and Communications Conference on May 20, and market watchers will be listening for any comments on capital allocation or share affordability that could reignite split speculation.

The technical picture shows some froth: the relative strength index sits at 73.5, and annualized volatility exceeds 80 percent. But with the next earnings report expected around mid-year, the fundamental narrative — a company that has sold out its entire next-generation production capacity years in advance — may matter more than any short-term overbought reading.
