Micron nears $1 trillion while UBS forecasts a potential increase to $1.8 trillion within a year.

      Timothy Arcuri raised his price target for Micron Technology to $1,625 from $535, driven by long-term HBM supply agreements that, according to him, transform the traditional boom-bust memory cycle into something resembling a structural duopoly. On Tuesday, Micron's shares surged by as much as 19% following Arcuri's announcement, which suggests a market capitalization nearing $1.8 trillion if the projection holds for the next year.

      This new target stands as the highest among the 46 analysts monitoring the stock, marking one of the most aggressive single-day valuations for any established semiconductor company on record. The rationale behind Arcuri’s prediction is compelling beyond just the numbers. UBS's premise is not based on the notion that AI demand will indefinitely increase memory prices, a common cyclical-optimistic argument. Instead, it centers on long-term supply agreements between memory manufacturers and their largest clients, particularly hyperscalers and Nvidia, which now secure enough market share to smooth out the traditional memory boom-bust cycle, creating a more stable earnings profile similar to utility companies.

      UBS estimates that up to 30% of global DDR memory volumes are already secured by pricing agreements slightly below current market rates, trading some immediate benefit for extended visibility. If this trend continues, Micron may evolve from being viewed as a cyclical commodity producer into more of a steady AI-infrastructure annuity. UBS projects that Micron's earnings per share will surpass $100 annually through at least 2029. Given the current valuations, this projection is significant enough to support a market cap closer to $1.8 trillion, rather than the roughly $1 trillion the company is valued at now; reaching the trillion-dollar mark was also unfathomable just a year ago.

      The HBM landscape is more nuanced than the headlines suggest. SK Hynix has been the standout player thus far, securing about 70% of HBM4 supply for Nvidia’s flagship Vera Rubin platform, with Samsung capturing most of the remainder. Initially, Micron was excluded from the premier VR200 NVL72 configuration but has since gained entry by supplying HBM4 for the Rubin CPX, a mid-range inference-oriented accelerator within the Rubin family, and commenced volume shipments of its 36GB 12H HBM4 stacks earlier this quarter.

      UBS's analysis essentially expects Micron to advance into the higher-end HBM4 supply tier within the next 18 months as SK Hynix and Samsung face challenges in scaling up to meet growing demand. The competitive landscape is worth noting; SK Hynix reached a $1 trillion market cap on Wednesday in Seoul and currently holds approximately 57% of the global HBM market share, while Samsung claims about 28%, with Micron being a smaller player. UBS asserts that the smaller entity will experience disproportionate benefits as the market grows, as customers seek a third supplier for risk management, even if the pricing within that tier is lower than that of the leading firms.

      While this thesis is reasonable, it is not guaranteed; it relies on Nvidia’s Rubin order book absorbing the projected HBM volume, and that SK Hynix does not secure the entire market potential. Other memory companies also experienced upward movement on Tuesday, with SanDisk rising 8% and Western Digital 10%, reflecting the indication that long-term agreements are permeating into NAND and traditional storage sectors. The pattern described by UBS, if accurate, signals a significant shift rather than just an isolated case for one stock.

      Micron's upcoming earnings report is scheduled for late June, and particular attention should be paid to its capacity-utilization guidance and any announcements regarding the expansion of its Nvidia HBM4 supply footprint in light of the new UBS target.
