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 

Kioxia looks cheap, and better than SanDisk, because NAND may have more demand torque than DRAM over the next 12-18 months as KV cache and AI content storage demand grows. Kioxia is cheaper than SanDisk and has a better KV cache offering. NAND does carry bigger long-term China supply risks. x.com  x.com 

Networking, power and compute look more durable than cyclical memory in the AI buildout. Lumentum's revenue compounded year after year across the 2010s and 2020s, unlike Micron's; AWS revenue also compounded. Lumentum, Nebius, Bloom Energy and Credo should heavily outperform SanDisk and Micron from here, though AI itself remains heavily doubted. x.com  x.com 

Kioxia's valuation gap with SanDisk should close as it pursues a US ADS listing, after the most violent earnings beat in memory this cycle. Hyperscalers are building AI data centers faster than NAND supply can keep up, so prices are surging: its SSD segment nearly doubled in a quarter despite lower shipments. Revenue rose 84.5% and operating profit 318%. It owns 51% of the fabs making SanDisk's chips and outsold it last quarter, yet is worth $152 billion to SanDisk's $208 billion. x.com  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's 74% operating margin is a shortage premium with an expiration date set by its own investor deck. AI inference storage demand is real, but management's supply-demand chart shows NAND returning toward balance by late 2027, and its long-term model targets mid-20% operating margins. The stock is about 12x the annualized peak quarter but roughly triple that on the company's normalized plan. The bull case: hyperscaler contracts and the inference-storage tier keep margins structurally higher. … Show more

SanDisk CEO David Goeckeler's report of customer signals beyond fiscal 2030 adds storage to the long-duration AI hardware-demand case. He says those signals come through new-business-model partnerships; Micron and SK hynix in memory and Lumentum in photonics were already cited as signs of demand beyond 2030. x.com 

SanDisk benefits as agentic AI explodes context data. Most of that KV cache cannot live in HBM, so it spills to QLC NAND, which is slower but the only tier economical enough at that scale. x.com 

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 

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
