Melius reiterates Micron stock Buy rating on tighter supply outlook

Micron's fiscal Q4 2026 adjusted EPS of $33.42 and revenue of $54.23B beat consensus estimates of $31.16 and $50.45B, while its November-quarter outlook of $38.15 EPS and $61.5B revenue also exceeded expectations. Melius said first-quarter guidance is 8% above consensus and expects tighter memory supply through 2028 as AI-driven high-bandwidth-memory demand absorbs capacity additions. More than 75% of fiscal 2027 revenue is committed, gross margins are projected to bottom at 86.25% before expanding, and Melius expects over $120B of share repurchases in calendar 2027.

Analysis

The investable signal is not the reported beat itself but the implied duration of HBM supply tightness: if long-dated customer commitments are real, MU can sustain a premium multiple versus its historically cyclical memory valuation. The operational leverage is unusually high because incremental HBM mix raises both pricing and utilization; a modest upward revision to FY27 gross-margin expectations would matter more to equity value than another near-term revenue beat. This favors MU over NAND-exposed storage names such as WDC and STX, whose earnings remain more vulnerable to commodity pricing and enterprise-demand volatility.

The central risk is that the figures and valuation claims in this AI-generated article require independent verification before capital is deployed. A 2027-31 supply agreement is not equivalent to take-or-pay demand, and customers may be reserving capacity defensively while qualification of competing HBM products expands. Samsung Electronics (005930 KS) and SK Hynix can respond through yield improvement or capacity conversion faster than new fabs come online; a faster competitor qualification cycle would compress HBM pricing and unwind the scarcity premium over 6-18 months.

Near term, consensus revisions and evidence of binding capacity allocation can support the stock, but a large one-year gain makes the risk/reward asymmetric if the market has already priced a multi-year supercycle. The contrarian view is that buyback enthusiasm may be overstated: capital intensity, working-capital needs, and strategic capacity investment can compete directly with cash returns. Treat any announced authorization as less important than actual quarterly repurchase execution and net-cash generation after capex.

Key Decisions for Investors

• Do not chase MU solely on this report; require confirmation from company filings/transcript of revenue guidance, committed-volume terms, HBM margin trajectory, and authorization details. If verified and MU holds above its post-results low for 5-10 trading days, initiate a 1-3 month tactical long with a 7-10% stop and target based on the next upward consensus EPS revision cycle.
• Express relative HBM tightness through long MU / short WDC in equal dollar amounts over 3-6 months. MU should outperform if HBM pricing and mix remain constrained while NAND pricing normalizes; exit if WDC NAND price revisions turn positive for two consecutive monthly checks or if MU HBM guidance is cut.
• For existing MU exposure, buy 6-9 month downside put spreads rather than adding outright after a sharp run. A structure financed by selling a farther out-of-the-money put limits carry while protecting against a competitor-driven HBM de-rating; reassess after Samsung and SK Hynix earnings/qualification updates.
• Monitor three falsifiers: HBM customer commitments falling below management's stated allocation levels, gross-margin guidance failing to expand despite higher revenue, or capex rising faster than operating cash flow. Any two occurring in one reporting cycle would invalidate the structural-margin thesis and warrant reducing MU exposure.
