Lisa Su just wrote substrates into AMD's five-year capacity plan, and the October 27 results test whether the models catch up. ## The clock moved to five years In Taipei on October 6, [AMD](https://theinference.org/markets/companies/amd) chief executive [Lisa Su](https://theinference.org/markets/people/lisa-su) said her company now plans capacity with partners three to five years out, up from one or two, and that wafers, packaging and substrates all need to be ready at the same time [1]. "We have increased our own supply and capacity this year, but demand exceeds supply," she told reporters [1]. Supply will rise substantially in 2027, she said, and the more-than-$10 billion Taiwan investment announced in May will grow because demand keeps outrunning it [1]. [TSMC](https://theinference.org/markets/companies/tsmc), the backend partners and the substrate suppliers are all expanding with that plan [2]. ## The land is bought; the customer is not That layer is where [Unimicron](https://theinference.org/markets/companies/unimicron) lives: a key substrate supplier to [Nvidia](https://theinference.org/markets/companies/nvidia), [Intel](https://theinference.org/markets/companies/intel), Google and [Amazon](https://theinference.org/markets/companies/amazon) [3]. ABF substrates were 52 percent of its [second-quarter revenue](https://www.ad-hoc-news.de/boerse/news/corporate-news/jpmorgan-stuft-die-unimicron-aktie-auf-overweight-ein/70253573), gross margin nearly doubled to 24.80 percent from 13.10 percent a year earlier, and January-to-August sales reached TWD 114.34 billion, up 34.2 percent [4]. On September 30 it disclosed TWD 10.09 billion, about US$313.7 million, for [19 plots and 14 factory buildings at Hukou](https://www.digitimes.com/news/a20261001PD200/unimicron-capacity-abf-substrate-taiwan-demand.html): 63,048 square meters of former Bridgestone land [5][6]. Nothing in that filing, or in [the 30-to-40-percent ABF capacity lift and late-2027 Guangfu ramp it anchors](https://theinference.org/article/unimicron-targets-up-to-40-more-ai-substrate-capacity-funded-by-no-one-but-itself) [7], carries a customer deposit, allocation or supply contract. Shareholders fund the whole bet [7]. Samsung Electro-Mechanics is doing it the other way: its 6.78 trillion won FCBGA build runs partly on customer advance payments against three-to-five-year volume guarantees, with lead times of 48 to 56 weeks against a normal 12 [8]. ## Nineteen Buys and a ceiling under the price Of 21 analysts, 19 rate the stock Buy and none Sell [4][5]. The median target is TWD 1,300, TWD 5 under the last price of October 7, TWD 1,305; JPMorgan's Overweight initiation of October 6 landed at TWD 1,225, and the range spans TWD 930 to 1,700 [4][5]. *Chart: **Nineteen Buys, zero Sells, and the targets sit under the price** Bar chart comparing Unimicron's last share price with analyst price targets in TWD per share* *TWD per share, Taiwan Stock Exchange. Last price is the 1:30 p.m. TST quote of October 7, 2026; targets from 21 covering analysts (19 Buy, 1 Hold, 0 Sell); JPMorgan initiated coverage on October 6. Sources: AD HOC NEWS, October 7 to 8, 2026 [4] [5]. [4][5]* The shares sit 8.11 percent below the TWD 1,420 high, at a TWD 2.1 trillion market value [5]. ## A prosecutor holds the other shoe The caution has a second source. [Prosecutors raided Unimicron's headquarters and a Zhongli plant on August 28](https://www.tomshardware.com/tech-industry/big-tech/key-nvidia-and-intel-supplier-raided-over-alleged-china-origin-fraud-unimicron-faces-probe-over-pcb-origin-washing-risk-of-40-percent-u-s-tariff-penalty) over alleged relabeling of China-made boards as Taiwanese, releasing the PCB unit's general manager on NT$15 million bail [3]. Proven transshipment into the US could trigger a 40 percent penalty falling on its American customers as importers of record, though the products in question are conventional PCBs, not the ABF substrates the expansion sells [3]. ## October 27 asks the question [Third-quarter results land on October 27](https://www.ad-hoc-news.de/boerse/news/corporate-news/unimicron-stock-funds-growth-with-a-twd-10-08888-billion-deal/70254086) [5]. Su is underwriting five years of substrates; on the disclosures to date, no buyer has underwritten one year of Unimicron. ## Takeaway AMD's plan now runs five years out and Unimicron has bought the land for a bigger ABF lift, but the land filing names no customer, 19 of 21 analysts are Buy while the newest target sits under the price, and a tariff probe holds the other shoe until October 27. ## Sources 1.
