Sandisk's growth is coming entirely from higher prices, not more bits shipped, which makes it hard to sustain. Revenue grew 97% quarter over quarter as almost every hyperscaler raised capex to cover rising prices. Its roughly 80% gross margin is excessive and customers resent it; as long as demand far exceeds supply it can keep both, but supply eventually catches up and margins will erode. The open questions are how long new fabs take and whether Sandisk or rivals add the supply. x.com  x.com  … Show more

Seagate's gross margin jump to 57.8% from 52.7% shows pricing power in a supply-constrained hard-drive market. AI data needs storage, hyperscalers seek capacity, and HAMR packs more terabytes into existing factories; roughly 90% of big-cloud data sits on hard drives. Sales reached $4.2B and next-quarter guidance of $4.8B beats the Street's $4.53B. This cycle looks to be accelerating rather than peaking. Overweight, $1,050 target. 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 

Sandisk's fundamentals haven't reversed, but the trade is shifting from price and margin expansion to how long ~80% gross margins can last. ASPs still rise but more slowly, and 83-85% margin guidance after 84.6% suggests a plateau. Long-term deals with 8 customers cover over half of FY2027 bits and about two-thirds of FY2028 at around 80% margins, trading upside for certainty. Consumer revenue fell 32% sequentially as high prices hit phones and PCs. The Aug 13 investor day is the next test. … Show more

SK hynix's five-year agreements with 14 major customers cover more than half its 2027-28 capacity, giving its memory earnings unusually long visibility. DRAM prices rose 28% and NAND 25% in the quarter, while operating profit reached 62.8 billion against 58.5 billion expected; Q4 DRAM shipments are guided up 25% from Q3. Those commitments support the view that demand is not peaking yet. Overweight, $400 target. 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 

SK hynix's exceptional margins and contracted capacity underpin a bullish outlook despite shares sitting around half their June high. Q3 operating margin reached 80%, up from 47% a year ago; long-term deals with 14 customers cover over half of 2027-28 capacity, and management expects demand to exceed supply through 2030. x.com 

Western Digital benefits from HDDs' low storage cost and growing cloud demand, with higher NAND prices adding pricing power. Nearline bit demand normally grows 20-25% with some deflation, while AI data growth now exceeds 30%; HDD costs ~$0.02-$0.03/GB versus ~$0.25 for NAND. Before AI, the consolidated, ~95% cloud-exposed market looked worth a low-to-mid-teens multiple of normalized EPS. Entry barriers are extremely high, but irrational competition among the three players is a risk. x.com  x.com  … Show more

Sandisk's earnings growth makes its valuation look unusually low, with guidance showing no slowdown. Revenue rose 378% year over year, and $52.5 GAAP EPS implies a 6.1 annualized P/E, below Micron's. Sandisk's roughly 85% gross margin also compares favorably with SK hynix's apparently sub-50% NAND margin. Next-quarter guidance calls for $12.2 billion-$12.6 billion of revenue and $55-$57 non-GAAP EPS. x.com  x.com  x.com 

Sandisk, Western Digital and Seagate are priced as if AI's borrowed demand is permanent. Server spending is growing 36.9% in 2026 and data center systems 31.7%, versus 10.8% for total IT, a gap funded by raided budgets, panic orders and record debt; data center debt issuance nearly doubled last year to $182 billion. Since April, P/S rose from 10.5x to 25.5x at Sandisk, 8.6x to 18.7x at Western Digital and 8.5x to 19.7x at Seagate. Stocks bought above 10x sales have historically lost money. x.com
