GlobalWafers raises $1.4 billion to lock in scarce silicon supply
What's the deal? GlobalWafersDealroom has a profile for this one. Try Dealroom → priced the largest equity offering in its history on September 22, selling 50 million global depositary receipts at $28.64 each to raise $1.43 billion. The world's third-largest silicon wafer maker said proceeds go first toward raw material purchases, alongside overseas investments and cutting interest expense.
Why raw materials? A supplier rarely raises equity to buy feed stock — it does so when it expects supply to grow scarcer and pricier. GlobalWafers plans to raise 12-inch wafer prices in the second half of 2026 on AI-driven demand, with its 12-inch lines fully committed across all sites.
The customer signal: Micron is putting up to $500 million into GlobalWafers' 300mm plant in Sherman, Texas, tied to a 10-year deal for the plant's output. The move is part of a stated $3 billion commitment to the US semiconductor supply chain for "critical input materials," with Micron flagging raw silicon wafers as a potential pinch point in the 2028-2030 window.
What could go wrong? The financials have yet to match the story. Second-quarter revenue fell 5% year over year to US$440M, and gross margin dropped 5.2 percentage points to 20.6% as depreciation from a three-year expansion lands.
The context: A near-doubling of EPS to US$0.23 was flattered by a mark-to-market gain on GlobalWafers' stake in Siltronic, not by operations. Shares recently traded near US$22.5, weeks after peaking around US$46.3.
The signal: The raise ranks near the top of comparable post-IPO equity deals — in the 96th percentile among energy rounds in Taiwan over the past four years. It points to a shift in where the AI buildout's real bottleneck sits: not in logic or memory fabrication, but in the silicon substrate every chip starts on.
