Bullish UMC thesis as a mature-node foundry play benefiting from demand for commodity silicon and potential US re-rating.

UMC — LONG The author argues the market overlooks UMC because over 80% of global chip volume is mature nodes used in cars, power, industrial and displays, where customers commit for 5-10+ years. He cites UMC's scale (about 50% of TSMC, 8+ million 12-inch equivalent wafers by 2026, 14nm FinFET with 50-60% better power efficiency than 28nm) and its Intel 12nm US collaboration. He thinks a US revenue shift could re-rate the stock and that this year will be UMC's year.

UMC + Intel are working on a 12nm process in the U.S. later this decade. If even 5–10% of revenue moves to U.S. fabs, the market probably re-rates this thing.
