Micron and SK hynix pricing in a memory shortage past 2030 extends the memory-cycle case beyond the Street's 2028 expectation. SK hynix's record quarter adds evidence: per Wall St Engine, revenue rose 328% to $78.9B, operating profit rose 632% to $62.8B, and operating margin hit 80%. Agentic and physical AI could add demand as they roll out. x.com  x.com 

Micron's surging memory revenue points to a supercycle. Its segment and NAND revenue charts show a sharp recent acceleration, while the stock tests its rising 30-week average. x.com 

Micron's projections are set so high that even great years may not be enough to meet them. Samsung's Q3 results show the risk: revenue of $145.6B missed the $150.7B estimate, and operating profit of $80.2B missed $81.1B. x.com 

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 

Sandisk's fast-growing data-center revenue strengthens its case among memory names with upside. Data-center revenue rose 61% quarter over quarter; revenue of $11.03B, adjusted EPS of $49.51 and adjusted gross margin of 85.1% all exceeded estimates. For upside among Micron, Sandisk and Kioxia, Micron ranks first, then Sandisk, then Kioxia, until further guidance. x.com  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 

Micron's Q4 FY26 confirms the memory supercycle. Revenue reached $54.23B, up 379% YoY, beating its own guidance by 6% and consensus by $3B, and Q1 FY27 guidance of $61.5B adds another 13%. Core data center revenue rose 56% QoQ to $18.0B at a 90% gross margin, with every segment above 83%. Customers prepaid $12.7B to lock in supply. Micron generated $62B of FY26 free cash flow after $27.4B of capex and holds $73.5B of cash against $5.2B of debt. x.com 

Micron's pricing strength should last, with management saying memory and storage supply and demand will be much tighter through 2028 and guiding 2027 stronger than 2026. Revenue rose 379% year over year and EPS 1,002%, with cloud, core data center, mobile/client and auto all up triple digits or more. Customer agreements rose to 26 from 16 quarter over quarter. 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

Micron's memory leadership remains intact because it is sold out into 2027. A red day does not change those fundamentals; anyone arguing it has topped must identify which part of demand breaks and when. x.com
