AUO hits 16-year high on NVIDIA glass-substrate talk: three keys to the panel shift
On Sept. 30 Taiwan's panel stocks grabbed the spotlight as AUO and Innolux both closed limit-up, with AUO at NT$38.55 — an roughly 16.5-year high — after a Sept. 24 Korean-media report said NVIDIA is evaluating glass substrates for next-generation AI chip packaging, a claim NVIDIA has not confirmed. Most analysts' price targets for AUO sit at NT$22.5–35.2, meaning the stock has run past most valuation models. The report lays out three keys: Chinese makers BOE, TCL CSOT and HKC are halting lines for 5–7 days over the National Day holiday, cutting utilization from about 82% to the low 70s and issuing price-hike notices that state no amount; AUO is rumored to be selling its L5C and L7A fabs to TSMC for about US$1.2 billion (roughly NT$38 billion), unconfirmed by both sides and complicated by HP and Samsung supply arrangements; and new businesses such as glass substrates, CPO and Micro LED remain in sampling and validation, with Yole projecting the glass-core substrate market at only "hundreds of millions of dollars" by 2030 and chairman Paul Peng saying maturity is two to three years away.
Whether glass substrates can solve warpage in AI chip packaging will shape the advanced-packaging supply chain, but today's rally rests largely on unconfirmed expectations.
