Samsung Electronics (005930 KS) is reportedly targeting 100% foundry utilisation in H2, driven by HBM4 base-die demand and rising 2nm AI/HPC orders, Chosun press release

• Profitability could return as early as Q3 or Q4, although sustained improvement will depend on 2nm yields rising above 70% to secure large-scale customer orders.

Foundry utilisation is the classic swing variable in Samsung's contract chipmaking unit: fixed costs are heavy, so the line between losses and profitability in the division has historically tracked loading rates far more than pricing. Episodes where the unit has guided toward full utilisation on the back of a single leading-edge node have tended to hinge on yield rather than demand, since headline orders at immature nodes carry cancellation and requalification risk. The stated threshold here, yields above roughly 70% on 2nm to convert interest into large-scale orders, is the tell the market has used before to distinguish genuine inflection from promotional reporting; sub-threshold yields mean revenue without margin. The HBM4 base-die angle is structurally different from prior foundry cycles because it ties the unit's recovery to Samsung's own memory roadmap, an internal demand source rather than external customer wins, which makes the load less contestable but also less indicative of competitiveness against the dominant foundry peer. Sourcing matters: a single domestic press report on utilisation targets has a mixed track record, and the usual confirmation sequence is capex commentary and foundry margin disclosure in the next quarterly print. Watch for rival customer commitments on the same node and any shift in Samsung's memory-foundry bundling of HBM4 supply.
