Shares of Nanya Technology (2408.TW) surged 8.7% to TWD 436 on July 28, extending a rally that has seen the stock climb from TWD 381 in under a week, as investors digested one of the most dramatic quarterly turnarounds in recent DRAM history.
A Quarter That Rewrote the Profit Ledger
Nanya posted Q2 net sales of NT$82.5 billion, up 68.2% sequentially and a staggering 684.2% year-over-year.
Net income hit NT$50.2 billion, up 92.6% from Q1 and reversing a net loss of NT$4.1 billion in the year-ago quarter.
Gross margin reached 79.5% and net margin hit 60.8% — levels that, for a traditionally cyclical memory maker, are almost unheard of. First-half earnings per share totaled NT$23.38 , meaning the stock trades at roughly 9.3x annualized first-half earnings — cheap if pricing holds, expensive if it doesn't.
Prices, Not Volume, Are Doing All the Heavy Lifting
Bit shipment remained flat quarter-over-quarter, indicating reliance on price increases rather than volume growth.
Management said the main growth drivers in 2026 are rising average selling prices and an improving product mix. That's a double-edged sword: margins look magnificent today, but any softening in DRAM contract prices — which historically swing violently — could compress them just as fast.
A $17 Billion Bet on AI Memory's Future
Nanya is accelerating capacity expansion with a new fab in Taishan, northern Taiwan, where total investment is expected to reach NT$500 billion (US$17 billion).
The first phase is scheduled to ramp in 2028 at up to 30,000 wafers per month, with full capacity of 45,000 wafers and extreme ultraviolet lithography beginning that year. To help fund this, Nanya raised NT$78.72 billion (~US$2.5 billion) via private placement from Sandisk, Solidigm, Kioxia, and Cisco Systems — strategic partners locking in future supply, not just passive investors.
AI Revenue Is Real but Still a Side Dish
AI infrastructure, including servers, contributed more than 20% of revenue.
Nanya's custom AI memory technology features a wide-input/output architecture designed for tight integration with AI chips, conceptually similar to high-bandwidth memory. But the company declined to give revenue timing on these projects because of customer confidentiality.
Meanwhile, management expects overall DRAM supply to remain constrained for several more quarters , giving Nanya a pricing umbrella — for now. The question investors must answer: is this a structural shift or a cyclical peak dressed in AI clothing?
