The Korea IR Council's Corporate Research Centre has projected that EO Technics (KOSPI: 039030), a South Korean manufacturer of laser-based semiconductor equipment, will generate revenue of ₩494.8bn in 2026, a rise of 29.9% year on year, with operating profit climbing 62.1% to ₩130.9bn.
The operating margin is expected to improve by 5.3 percentage points to 26.5%, driven largely by a higher share of semiconductor equipment in the company's sales mix—a more profitable segment than its other product lines.
Chiplets open new doors
The shift towards chiplet architectures in AI semiconductors is creating fresh demand for EO Technics' tools. New equipment requirements have emerged in heat-spreader and electromagnetic-interference (EMI) shield marking processes, and the company has been selected as the standard equipment supplier by a leading North American GPU maker—widely understood to refer to Nvidia. This is prompting outsourced semiconductor assembly and test (OSAT) firms and packaging contractors to accelerate their own equipment purchases.
Laser annealing gains momentum
Demand for laser annealing equipment is also expected to grow. In DRAM, the increasing number of extreme ultraviolet (EUV) lithography machines deployed per production line, combined with broader capital investment by customers, is anticipated to lift orders. In NAND flash, meaningful adoption of laser annealing tools is forecast to begin in earnest at layer counts above 400.
Cutting equipment rides the HBM wave
In cutting equipment, growth is expected to be sustained by shipments of ultra-short-pulse laser tools used in high-bandwidth memory (HBM) production. Revenue from this segment has expanded sharply, rising from roughly ₩10bn in 2023 to an estimated mid-₩50bn range in 2025.
Samsung dependency remains a concern
The principal risk flagged in the report is the company's heavy reliance on Samsung Electronics, which currently receives laser annealing equipment on an exclusive basis. The report acknowledges that customer diversification is under way and expects this concentration to ease gradually as new semiconductor fabrication plants come online.
Recent performance
For 2025, EO Technics recorded revenue of ₩380.9bn, up 18.7% year on year, and operating profit of ₩80.8bn, a near-threefold increase of 158.8%. The semiconductor segment's share of total revenue expanded from roughly 60% in the prior year to 80% in 2025. As of 19th June, the company's shares were trading at ₩498,500, giving it a market capitalisation of approximately ₩6.14trn (around $4.5bn).
