Micron nears $1 trillion as UBS envisions a trajectory towards $1.8 trillion within a year.

      Timothy Arcuri increased his price target for Micron Technology to $1,625 from $535, driven by long-term HBM supply agreements that he believes will reshape the volatile memory cycle into a more stable structural duopoly. On Tuesday, shares of Micron Technology surged by as much as 19% following Arcuri's major increase in his price target, suggesting a market valuation nearing $1.8 trillion if this prediction holds true over the next year.

      This new price target stands as the highest among the 46 analysts tracking the stock and marks one of the most significant single-day reevaluations for an established semiconductor company in history. The rationale behind Arcuri’s forecast is more intriguing than the figure itself. UBS posits that the demand from AI won't indefinitely drive up memory prices, which is the typical cyclical argument; rather, it believes that long-term supply agreements with major customers, particularly hyperscale companies and Nvidia, now encompass enough of the market to stabilize the traditionally erratic memory cycle into a utility-like earnings profile.

      UBS estimates that as much as 30% of global DDR memory sales are already secured by pricing agreements set slightly below current market prices, sacrificing some short-term upside for years of reliable revenue outlook. If this trend continues, Micron may transition from being viewed as a cyclical commodity producer to resembling an annuity for AI infrastructure. UBS anticipates that Micron's earnings per share will surpass $100 annually through at least 2029. Given current valuations, this could support a market cap closer to $1.8 trillion rather than the approximately $1 trillion at which the company is currently valued—a threshold that seemed unimaginable just a year ago.

      The HBM landscape is more nuanced than it initially appears. SK Hynix has emerged as the dominant player thus far, controlling around 70% of HBM4 supply for Nvidia's leading Vera Rubin platform, while Samsung accounts for most of the remainder. Initially, Micron was excluded from the primary VR200 NVL72 configuration but has since secured a role supplying HBM4 for the Rubin CPX, a mid-range inference-oriented accelerator within the Rubin product line, and has begun volume shipments of its 36GB 12H HBM4 stacks earlier this quarter.

      UBS's assumption hinges on Micron's continued advancement into the higher-end HBM4 supply segment over the next 18 months, particularly as SK Hynix and Samsung may struggle to scale up quickly enough to meet demand. The competitive dynamics are noteworthy; SK Hynix reached a market capitalization of over $1 trillion on Wednesday in Seoul, holding about 57% of the global HBM market share, while Samsung accounts for roughly 28%, leaving Micron as the smaller player. UBS suggests that the smaller competitor may gain disproportionately as the market grows since customers are seeking a third source for risk management, even if the pricing for that third source is lower than that of the market leader.

      This thesis is credible but not guaranteed; it presumes that Nvidia's Rubin orders will indeed consume the projected HBM volumes and that SK Hynix won't capture all the potential upside. The broader memory sector also reacted positively on Tuesday alongside Micron. SanDisk shares rose by 8%, and Western Digital's shares climbed by 10%, reflecting the expectation that long-term agreements are extending into NAND and traditional storage markets. If UBS's analysis holds true, it could signify a major shift in the category rather than being confined to a single stock.

      Micron's next earnings report is scheduled for late June. The most critical figures to monitor will be capacity utilization guidance and any announced expansion of its HBM4 supply for Nvidia, particularly in light of the new UBS price target.
