Kioxia faces eroding pricing power as surging chip production capacity threatens the storage-chip boom. TSMC's signal of a hike in 2026 capex to $64 billion fed fears that new capacity will erode the pricing that made memory a gold mine, amid broader doubts that AI spending turns into stable profits. The stock has fallen 52% from its June highs. After a 600% climb on retail leverage, the descent is rarely gentle, and in cyclical industries supply-side realities catch up to the hype. x.com 

SK hynix's signed long-term cloud contracts give its AI-memory demand greater visibility and may support sustained pricing. Fourteen agreements cover over 50% of 2027-28 production capacity; HBM4 shipments are ramping, with the company expecting HBM4 to exceed HBM3E in volume and revenue by Q4 2026. AI-memory cash generation and Kioxia investment gains also underpin planned 2026 shareholder returns of about 100 trillion won, including dividends and buybacks. x.com  x.com 

Kioxia is gaining NAND share as AI eats through storage, while Samsung and SK hynix shift resources to HBM. Staying focused on NAND has given it production costs 20-30% below competitors. Its quarterly operating profit hit $3.8B, passing Toyota as one of Japan's most profitable businesses, with about $15B of net income expected in 2027. Even after rising 2,000% in a year it trades at 8.9x forward earnings and is preparing a US listing. The key question is whether NAND pricing holds. x.com  x.com 

SK hynix's contracted capacity and demand outlook make its record quarter hard not to like. Agreements with 14 major customers cover over half of 2027-28 capacity; it expects demand above supply through 2030. Q3 revenue of $78.8B and operating profit of $62.8B beat $74B/$58B Street estimates, its first quarter above ₩100T with near-80% margins. It guides roughly ₩100T in FY26 shareholder returns, including a ₩20,000 Q3 dividend, half a one-off Kioxia special. x.com 

SanDisk's data-center flash growth shows AI inference is becoming a larger storage customer. Data-center revenue reached $4.8bn, up 61% in a quarter and over 40% of sales; total revenue of $11bn and EPS of $49.51 beat expectations. Guidance of $12.4bn revenue and $56 EPS suggests feared supply normalization has not yet eroded pricing. Overweight, with a $2,700 target. x.com  x.com 

Kioxia looks cheap at about 5x next-twelve-month earnings as the NAND supercycle drives a massive profit surge. Q1 FY2026 revenue rose 415.5% year over year and net profit reached ¥842 billion versus ¥18 billion a year earlier, while the equity ratio climbed from 37.9% to 50.8%. First-half guidance implies Q2 EPS of about ¥2,322, up 51% on Q1; annualized, that is about ¥9,289 against a ¥46,000 share price. The open question is whether the cycle lasts or earnings peak sooner. x.com 

Sold-out HBM and cash returns make SK hynix look too cheap for a memory cycle that has not ended. Its HBM capacity is sold through 2027, 12-layer HBM4 is shipping, and next year's HBM prices are forecast to rise 121%. A completed ₩40T buyback adds shareholder returns; a special dividend funded by a Kioxia stake sale is possible. At roughly 4x earnings by one estimate, the shares could go higher if the AI memory cycle persists. x.com 

AI data and content creation could lift Seagate's and Western Digital's cross-cycle earnings even if supply catches up and pressures prices and margins. Western Digital reported hyperscaler demand signals through 2030/31, making 2013-2024 normalized earnings a poor baseline. Still not a huge fan of their stocks given their large premium to memory makers and Toshiba's production ramp. x.com  x.com 

Kioxia and SanDisk are the purer bets on NAND and enterprise SSDs, with more torque to QLC, KV-cache and offload storage, and Kioxia trades at a far lower multiple. Enterprise SSD is where the memory supercycle is being priced, as US cloud providers raised eSSD demand forecasts and QLC emerges as the cost-efficient growth driver, per a post citing TrendForce. x.com 

Kioxia's need to do a buyback is proof that the flash-memory boom is over. x.com
