Micron climbs to record high as UBS calls for structural AI re-rating

Shares of Micron Technology (NASDAQ:MU) surged to an all-time intraday high following a dramatic price target increase from UBS, which argued that the artificial intelligence infrastructure buildout has permanently altered the financial predictability and valuation framework of the memory chip industry.

Micron shares jumped more than 10% in early Tuesday trading, marking the company’s 30th intraday record high of the year.

The rally was triggered by UBS analyst Timothy Arcuri, who more than tripled his price target on the stock to $1,625 from $535.

The new target represents a Street-high figure on Wall Street and implies roughly 116% upside from the stock’s previous closing price.

Should the Boise, Idaho-based semiconductor manufacturer reach the UBS target, its total market capitalization would swell to approximately $1.8 trillion.

A valuation of that scale would position Micron as the seventh-largest publicly traded company in the United States, placing it behind major technology peers such as Nvidia, Alphabet, Apple, Microsoft, Amazon, and Broadcom, while overtaking corporations including Tesla, Meta, and Berkshire Hathaway.

The core of the bullish thesis rests on an ongoing transformation in how memory suppliers structure commercial relationships with major cloud computing providers and enterprise buyers.

Arcuri highlighted that newer three-to-five-year Long-Term Agreements (LTAs) across the industry now incorporate fixed volume commitments paired with partially fixed pricing mechanisms.

This structural adjustment departs from historical industry practices, which were heavily tied to fluctuating spot-market volumes and raw commodity cycles.

According to the research note, these structural supply contracts give Micron a far smoother cross-cycle revenue profile and better visibility into future demand, dampening the volatile booms and busts that have traditionally defined the DRAM and NAND memory sectors.

Consequently, UBS sharply adjusted its financial forecasts upward, projecting that Micron’s earnings per share will remain structurally above $100 through calendar year 2029, generating over $400 billion in cumulative free cash flow during that period.
