Micron’s blowout Q4 2025 on AI memory demand; HBM nearly $2B in Q4, FYQ1 guide tops estimates (Sep 23, 2025). Micron posted $11.3B revenue and $3.03 EPS (non-GAAP), guided FYQ1 revenue to $12.5B with ~51.5% adj. gross margin, and said HBM capacity for 2026 is selling out; AI data-center memory now ~40% of sales. Winners -U.S. memory makers (pricing power and AI mix shift)Reason: Micron’s beat and guidance signal tight DRAM supply, improving NAND pricing, and multi-year HBM upcycle; peers leveraged to the same pricing tailwinds. $MU (Micron Technology) — direct beneficiary of AI-driven DRAM/HBM demand and better pricing.$WDC (Western Digital) — U.S. NAND supplier geared to enterprise SSD growth alongside AI server builds. AI accelerators and platforms (HBM availability underpins GPU shipments)Reason: HBM3E/next-gen HBM is the critical bottleneck for AI GPUs; Micron’s ramp and sold-out 2026 capacity support continued accelerator shipments and pricing. $NVDA (NVIDIA) — core HBM customer; more HBM supports sustained data-center GPU output.$AMD (Advanced Micro Devices) — expanding MI300/MI325 family; benefits from increased HBM supply and maturing ecosystem.Wafer-fab equipment (HBM and advanced DRAM capex)Reason: Micron’s FY25 capex was ~$13.8B to expand advanced nodes/HBM; sustained spend benefits U.S. WFE suppliers. $AMAT (Applied Materials) — process tools across DRAM/HBM lines.$LRCX (Lam Research) — etch/deposition demand rises with DRAM/HBM layer complexity.Losers -PC and device OEMs (higher memory costs pressure margins)Reason: Tight DRAM and improving NAND pricing raise BOM costs; mix favors data center over consumer, squeezing PC/device margins near term. $HPQ (HP Inc.) — sensitive to component cost inflation.$DELL (Dell Technologies) — client PC mix exposed to memory price updraft.Hyperscale spenders, near term (capex and unit costs stay elevated)Reason: Premium HBM pricing and sold-out capacity keep AI infrastructure costs high, a near-term drag on free cash flow even as long-term demand is positive. $AMZN (Amazon) — AWS continues heavy AI infrastructure build-out.$MSFT (Microsoft) — Azure’s AI expansion implies sustained capex intensityHDD-centric and legacy storage (AI favors SSD/flash; component price hikes)Reason: AI workloads prefer high-throughput NVMe SSDs; multiple reports flag tightening supply and price increases across storage components. $STX (Seagate) — HDD share at risk as SSDs take more AI storage.$NTAP (NetApp) — array vendors face higher flash component costs and mix shift toward cloud AI storage.#Micron #MU #Earnings #HBM #AI #Semiconductors #NVDA #AMD #WFE #AMAT #LRCX #TechStocks #DataCenter #Stocks
