[News] Samsung May End UMC’s Galaxy DDI Exclusivity by Adding GlobalFoundries as Mature-Node Capacity Tightens
Samsung may add GlobalFoundries as a second supplier for display driver ICs (DDIs) in its Galaxy smartphones, potentially ending UMC's exclusivity. This follows UMC's capacity constraints due to high demand, particularly for the Galaxy Z Fold8. Samsung is evaluating GlobalFoundries' 22nm or 28nm nodes for DDI production, with possible adoption in late 2027. UMC's capacity utilization is expected to reach 93% by the end of 2026, with price increases anticipated in 2027.

The 30-second read
Why it matters
The shift could reshape mature-node foundry dynamics, raising prices and reallocating capacity to AI-related products.
Market read
Supply-chain realignment may affect UMC stock and mature-node pricing across the sector.
What to watch
Potential new contracts with Apple or other OEMs may mitigate the impact.
Background
Samsung is evaluating GlobalFoundries for 22nm/28nm display driver ICs as mature-node capacity tightens, possibly ending UMC's exclusivity.
Ticker impact
Samsung may end UMC's exclusive DDI supply, adding GlobalFoundries, which could reduce UMC's revenue from Samsung display driver ICs.
downward pressure as the market prices in reduced Samsung demand.
UMC's mature-node capacity is already tight; losing a major customer like Samsung could hurt margins.
Market effects
Mature-node foundry sector may see tighter supply and higher pricing, benefiting rivals with spare capacity.
Korea and Taiwan foundry markets could see shifts in order flow.
Limited to semiconductor supply chain; no broad market impact.
Counterpoint
UMC could benefit from higher pricing on remaining capacity, offsetting lost Samsung volume.
