Micron's HBM and server-memory scarcity is backed by customer commitments beyond its earlier sold-out 2026 capacity. Per management and sell-side reports, more than about 75% of fiscal 2027 shipments are allocated or contracted, supply may not rebalance through 2028, and 2027 HBM prices have risen significantly. Strategic agreements extend through 2030; a later supply glut or faster Chinese competition could erode margins. x.com 

HBM production and pricing growth make Micron's roughly 6x forward multiple catastrophically wrong to imply an earnings collapse by 2029. HBM production is set to grow 700%, while Bloomberg Intelligence projects prices rising from $13 to $35 per GB by 2030. Micron's HBM business will then make up 70% of revenue, with margins tripling. Getting the memory cycle's end wrong by just two years can badly distort stock forecasts; the market is off by ten. x.com 

Micron's roughly $1.37 trillion valuation already prices a durable rise in through-cycle earnings that memory's history has never shown. A reverse DCF at 9% WACC and 2% growth implies about $95 billion of steady cash flow, versus a record $9.2 billion and a ten-year average near $1.9 billion. At a 30% FCFF margin that needs about $317 billion of revenue, over 8x fiscal 2025 sales. The HBM bull case is real, but fiscal 2023's swing to a -37% operating margin shows how fast pricing reverses. x.com 

Hynix's sold-out memory supply supports expectations for big numbers from Micron, still trading at 5x forward earnings. Hynix says its HBM and DRAM chips are sold out until 2029 and a chip shortage is likely to continue into 2030. Big numbers and capital return are expected after Micron reports in December. x.com 

Micron's ordinary memory could see tighter supply because HBM consumes far more factory capacity than conventional DRAM. Meeting AI demand could thus extend Micron's opportunity beyond AI memory. x.com 

Micron's risk-reward for longs is unappealing because Chinese memory makers could crush the non-HBM profits that still make up most of its earnings. State-backed firms such as CXMT trail in HBM but can aggressively expand low-end capacity if Beijing wants, as China has done elsewhere. HBM growth is unlikely to offset that: memory nears 50% of rack bill of materials, and Micron locking in half its revenue for five years at capped prices suggests pricing has peaked, leaving growth to volume. x.com  … Show more

SK hynix's sold-out memory capacity bodes well for Micron because it sells into the same shortage. SK hynix says its DRAM and HBM are effectively sold out through 2029; deals with 14 customers cover more than half its 2027-28 capacity, and HBM demand is twice what it can make. x.com 

HBM advances are creating strong, durable moats and long-term pricing power for Micron and SK hynix. x.com 

Micron is at its top because memory stocks peak when margins peak, well before the shortage flips to oversupply, expected by 2028. Memory is tech's most brutally cyclical business: shortage, record prices, margins and capex, then new capacity arrives at once and becomes a glut. Micron trades at record highs on record DRAM prices, with memory's biggest capex wave under construction. In past oversupply cycles it fell 90% in 2000, 80% in 2008, 50% in 2018 and 47% in 2022. x.com 

Micron can benefit both from HBM pricing catching up in 2027 and from the HBM ramp keeping conventional DRAM supply tight. HBM does not need to become the higher-margin product for that to work. x.com
