Samsung looks to outside suppliers as HBM boom shifts priorities

Samsung's shift toward external HBM sourcing signals a structural change in its vertical integration model, driven by technological evolution and shifting market demands. This move undermines its control over packaging and increases supply chain complexity and costs. From a compliance standpoint, the ongoing global semiconductor realignment—especially amid U.S.-China tech decoupling—forces Samsung to weigh production efficiency against geopolitical risks. Competitors such as SK Hynix and Micron may capitalize on this by expanding HBM market share and deepening AI customer ties. Over the next 12–24 months, HBM supply constraints will persist, accelerating industry fragmentation and flexibility. Samsung’s internal realignment will be a critical determinant of its competitive trajectory.
