At $900 Billion, Micron Sheds Its Cyclical Skin — Bank of America Lays Out a Two-Tier Valuation

Micron's market cap tops $900B as AI-driven HBM demand, supply constraints, and a Bank of America price target hike to $950 revalue the chipmaker beyond cyclical norms.

Micron’s blistering rally has carried it past a psychological threshold, but the real story lies in how the market is re-rating the memory maker. On Wednesday, the stock closed at $803.63, a gain of 4.83% that pushed the company’s market capitalization above $906 billion. The milestone reflects a confluence of factors: insatiable AI-driven demand for high-bandwidth memory, a structural supply squeeze, and a major analyst upgrade that effectively rewrites the valuation playbook for the chip sector.

Bank of America wasted no time capitalizing on the momentum. The firm lifted its price target to $950 from $500, maintaining a “Buy” rating. The rationale marks a departure from how memory stocks have traditionally been evaluated. According to the note, Micron’s business should now be split into two distinct value blocks: the AI and HBM segment, worth roughly $240 per share, and the legacy DRAM and NAND operations, contributing about $710 per share. The message is clear — this is no longer a textbook cyclical play.

The crux of the upgrade lies in supply dynamics. Bank of America expects the industry’s supply-to-demand ratio to remain below 110% through 2028, signaling persistently firm pricing. Capacity growth, packaging bottlenecks, and power constraints are all tightening the screws. Every new data center build-out amplifies the pressure, and hyperscalers are spending accordingly. Amazon and Microsoft are each budgeting close to $200 billion on AI-related capex through 2027, with Alphabet close behind. Meta has already revised its own forecast upward, explicitly citing higher memory prices as a driver.

Micron’s product pipeline is feeding directly into that demand. On May 12, the company announced first samples of new 256-GB DDR5 RDIMM modules aimed at AI server workloads. The modules hit 9,200 megatransfers per second while slashing power consumption by more than 40% compared with configurations using multiple 128-GB sticks. Energy efficiency is becoming a decisive factor as electricity constraints emerge as the next bottleneck in hyperscale computing.

The operational numbers underscore the transformation. Micron reported second-quarter revenue of nearly $24 billion, a 196% surge from the prior year. Capital expenditures for the current fiscal year are set to exceed $25 billion, double the prior year’s level. The entire HBM production pipeline through the end of 2026 is already sold out. To meet demand, construction is underway on a $100 billion megafab in New York, while a new wafer facility in Singapore will cost $24 billion over a decade.

Yet even as the fundamentals dazzle, insiders are cashing out. Over the past three months, executives have sold roughly $52.4 million worth of shares. Director Steven J. Gomo alone offloaded 2,000 shares for about $1.57 million. CEO Sanjay Mehrotra has also locked in gains, and two U.S. congressmen, Tony Wied and Cleo Fields, reported profits of up to 122% on their personal trades — amounts that in some cases exceeded their annual congressional salaries.

The valuation has become a source of debate. The trailing price-to-earnings ratio stands at 37.94, well above the five-year median of 20.72. GuruFocus data pegs the current price about 138% above its calculated fair value of $336.93. For a memory manufacturer, such a premium leaves little margin for error. The rally effectively bets that AI-driven memory shortages will persist for years. Should supply loosen faster than anticipated, the stock could prove vulnerable. For now, however, the combination of sold-out production, deepening capex, and a deliberate re-rating by Wall Street suggests Micron is riding a structural shift — not just another cyclical upswing.
