3 South Korean Power Stocks Behind The AI Data Center Buildout

South Korea is pouring record public money into chips, AI and data centers, and that kind of focused spending can reshape which stocks quietly pull ahead while others struggle to keep up. Investors watching this shift risk missing the move if they only track headline tech brands instead of the pipes, power and cooling that keep AI running. This article examines three South Korean stocks that are connected to that policy trend and explains their role in the evolving landscape.

The three stocks that follow are just a sample set, and the full screen on Simply Wall St surfaces 20 more South Korean AI data-center power and infrastructure companies with equally compelling narratives that are not covered here. To identify where you want to focus first, head straight to the South Korean AI Data-Center Power & Infrastructure Enablers screener and analyze which power, grid and cooling enablers best fit your own thesis.

HD Hyundai Electric (KOSE:A267260)

Overview: HD Hyundai Electric manufactures transformers, switchgear, motors and related power equipment that support high capacity grids for AI data centers and semiconductor fabs.

Market Cap: ₩15.3t

HD Hyundai Electric is closely tied to the AI data-center buildout theme, supplying transformers, switchgear and grid equipment that handle heavy, constant power loads. Earnings forecasts indicate potential expansion, margins appear solid, and governance looks reasonably balanced. Investor returns, however, still depend on how conditions evolve if there is a shift in project funding and capital expenditure appetite.

If you want to see how those projects and margins line up in detail, start with the analysis report for HD Hyundai Electric to identify what the headlines are missing.

LS (KOSE:A006260)

Overview: LS runs a diversified electric power, automation, cable, and materials group that supplies infrastructure systems to large industrial and semiconductor facilities.

Operations: LS generates about ₩18.7t from materials, ₩5.7t from power lines and cable, and ₩4.6t from the power sector, with most sales in Korea.

Market Cap: ₩5.5t

LS plugs directly into the AI data center theme through power and automation gear used in large industrial and chip facilities. The shares trade on a P/E that some investors view as undemanding relative to currently forecast earnings growth and existing government support for infrastructure-heavy projects. Investor interest also reflects how funding costs and leverage may influence the eventual payoff from that demand.

Those funding questions make it even more important to review the 5 key rewards and 1 important major warning sign before funding costs or leverage begin to mask the full opportunity.

LS ELECTRIC (KOSE:A010120)

Overview: LS ELECTRIC provides smart energy and automation equipment for grids, substations, data centers and semiconductor facilities in Korea and overseas.

Operations: Most revenue comes from the ₩5.98t Power Sector and ₩573b Automation Division, with smaller contributions from IT and metals activities.

Market Cap: ₩22.3t

LS ELECTRIC sits squarely in the AI data center buildout, supplying power management and grid gear that keep high load facilities running. Recent results show strong profitability from these infrastructure projects, yet the stock trades on a rich P/E multiple that already appears to reflect substantial success. Investor outcomes now depend on how one less visible pressure affects future cash conversion and pricing power.

That pressure point is exactly why the 3 key rewards and 1 important major warning sign could be the edge you need before cash conversion and pricing power start to decouple.
