Micron nears $1 trillion as UBS identifies a route to $1.8 trillion within a year.

      Timothy Arcuri raised his price target for Micron Technology from $535 to $1,625, attributing this increase to long-term HBM supply agreements that, in his view, transform the cyclical memory market into a more stable structural duopoly. As a result, Micron's shares surged nearly 19% on Tuesday, following Arcuri's more than tripling of his price target, which indicates a potential market valuation near $1.8 trillion if this forecast holds true over the coming year.

      This new price target is the highest among the 46 analysts tracking the stock and marks one of the most extreme single-day re-evaluations of a well-established semiconductor firm on record. The rationale for Arcuri’s prediction delves deeper than just the number itself. UBS’s argument is not solely based on the belief that AI demand will continually drive memory prices upward, which is a typical cyclical argument. Instead, UBS contends that long-term agreements between memory manufacturers and their largest clients, especially the hyperscalers and Nvidia, now encompass a substantial portion of the market, thereby smoothing out the traditional boom-bust memory cycle into a more predictable utility-style earnings model.

      UBS estimates that approximately 30% of global DDR memory volumes are already linked to pricing agreements that are set slightly below current spot prices, offering some short-term upside in exchange for longer-term visibility. If this trend continues, Micron may begin to resemble less of a cyclical commodity producer and more of a steady income generator in AI infrastructure. UBS predicts that Micron's earnings per share will surpass $100 annually through at least 2029. Given current valuations, this projection is sufficient to support a market capitalization closer to $1.8 trillion, rather than the roughly $1 trillion at which the company is currently trading; reaching a trillion-dollar valuation seemed unfathomable just a year ago.

      The situation surrounding HBM is more complex than the headline indicates. SK Hynix has significantly benefited during this cycle, currently holding about 70% of HBM4 supply for Nvidia’s prominent Vera Rubin platform, with Samsung acquiring most of the remaining share. Micron was initially excluded from supplying the flagship VR200 NVL72 configuration but has since secured a role in the HBM4 supply for the Rubin CPX, a mid-range inference-focused accelerator within the Rubin portfolio, and commenced volume shipments of its 36GB 12H HBM4 stacks earlier this quarter.

      UBS’s thesis essentially suggests that Micron will progressively move into the higher-end HBM4 supply tier during the next 18 months, as SK Hynix and Samsung face challenges in scaling up fast enough to meet demand. The competitive landscape deserves attention; SK Hynix reached a market capitalization of over $1 trillion on Wednesday in Seoul and currently commands about 57% of the global HBM market share. Samsung holds roughly 28%, while Micron has maintained a smaller presence. UBS’s hypothesis implies that the smaller player may benefit disproportionately as the market grows since customers are seeking a third supplier for risk diversification, even if the pricing for that third option is lower than that of the leading supplier.

      While the thesis is credible, it is not guaranteed; it relies on Nvidia’s Rubin order book actually utilizing the forecasted HBM volume and assumes that SK Hynix does not capture the entire upside. The wider memory market also reacted alongside Micron on Tuesday, with SanDisk increasing by 8% and Western Digital by 10%, reflecting the notion that long-term agreements are extending into NAND and traditional storage as well. The trend UBS describes, if valid, suggests a fundamental shift rather than merely a singular stock event.

      Micron is expected to release its next earnings report at the end of June. Investors should closely monitor the capacity utilization guidance and any announced expansion of its Nvidia HBM4 footprint in light of the new UBS price target.
