Overview
- Major firms published third‑quarter and year‑to‑date results on Thursday showing an earnings boom led by Samsung and GigaDevice with outsized year‑on‑year profit gains.
- Samsung reported preliminary Q3 consolidated net income of 75.21 trillion KRW, a more than fivefold jump from a year earlier, and said memory and HBM sales drove most of the profit surge.
- GigaDevice posted a 921% rise in first‑nine‑month net profit and several optical, PCB and module suppliers recorded double‑digit to multi‑hundred‑percent profit growth tied to AI compute demand.
- Companies are responding with capacity expansion, higher capital spending, share buybacks and offshore debt issuance, which is increasing depreciation and working‑capital pressure for some suppliers.
- Key risks that could slow the cycle include a normalization of memory and optical prices, delays in HBM4/HBM4E customer validation and rising inventory, receivables and FX effects that may strain cash flow.
