Samsung to Exit 8-inch Wafer Foundry Business by 2030

The significance lies less in the exit itself than in what it signals about the low end of the foundry stack: 8-inch capacity serves mature-node, cost-sensitive chips, and a major player stepping away suggests those economics no longer clear an internal bar at Samsung. The customers who relied on that capacity face a re-sourcing question, and the suppliers and smaller foundries positioned around mature nodes are the ones to watch as demand shifts. Samsung has disclosed no timing or scope beyond the 2030 horizon, so whether this proves a targeted retreat or the start of a broader recalibration of its foundry footprint is the open question.
