As competition in artificial intelligence data centers spreads from semiconductor procurement to power-grid construction, the growth trajectory of Hyosung Heavy Industries is becoming increasingly clear. Governments and utilities are simultaneously replacing aging transmission systems, connecting renewable energy and securing electricity for data centers, strengthening the position of companies capable of supplying ultra-high-voltage transformers, circuit breakers and grid-stabilization equipment.
Hyosung Heavy Industries reported consolidated revenue of KRW 1.687 trillion and operating profit of KRW 264.3 billion for the second quarter of 2026. Revenue increased 10.6 percent from a year earlier, while operating profit surged 60.9 percent to a quarterly record. The more important signal is profitability: rising sales of high-value power equipment, particularly in North America, have allowed earnings to grow far faster than revenue.
New orders in the heavy industries division reached KRW 3.324 trillion during the quarter, up 51 percent year on year. First-half orders exceeded KRW 7.5 trillion, while the order backlog climbed to a record KRW 17.5 trillion at the end of June. Hyosung Heavy Industries consequently raised its 2026 annual order target by 43 percent, from KRW 8.4 trillion to KRW 12 trillion—approximately 58 percent above its total new orders of KRW 7.6 trillion in 2025.
What matters is not only the volume of orders but also their composition. The United States accounted for 38 percent of the division’s second-quarter revenue, an increase of 15 percentage points from a year earlier, while North America represented 57 percent of its order backlog. These figures show the company evolving from a heavy-equipment manufacturer exposed to domestic capital spending and construction cycles into an export-driven supplier tied to long-term North American grid investment.
North American manufacturing becomes a gateway to the market
Demand for power equipment in the United States is being driven by four forces at once: AI data-center construction, manufacturing reshoring, renewable-energy integration and the replacement of aging grid infrastructure. Ultra-high-voltage transformers, however, cannot be supplied quickly. They require customized engineering, lengthy certification and testing, and a proven record of installation and maintenance.
The Memphis plant in Tennessee, acquired by Hyosung Heavy Industries in 2020, is therefore more than another production facility. It is the only plant in the United States capable of designing and manufacturing 765-kilovolt ultra-high-voltage transformers. The company plans to invest an additional $157 million by 2028 to expand the plant’s production capacity by more than 50 percent.
The strategic value of Memphis extends beyond reducing tariff exposure. Local manufacturing enables faster responses to design changes, urgent orders and maintenance requirements from US customers. By combining the manufacturing expertise of its Changwon plant in South Korea with the market access of Memphis, Hyosung Heavy Industries can draw on both Korean production efficiency and American supply-chain proximity.
This dual production structure becomes more valuable as delivery times lengthen across the transformer industry. Utilities procuring mission-critical equipment place a premium on reliability and delivery certainty, not simply on the lowest price. Hyosung Heavy Industries is positioned to offer both advanced technology and a credible local supply base.
The company is also establishing a circuit-breaker manufacturing joint venture with Quanta Services, one of the largest electric power and energy infrastructure contractors in the United States. The partnership expands Hyosung Heavy Industries’ localization strategy beyond transformers and into another essential part of the transmission network. Combining Quanta’s project pipeline and customer relationships with Hyosung’s ultra-high-voltage technology could allow the Korean company to participate earlier in project development rather than enter only at the equipment procurement stage.
This marks a deeper shift in its North American strategy—from manufacturing in South Korea and exporting to the United States to producing and supplying equipment from within the US power-grid ecosystem. In an industry where operating history and utility relationships carry as much weight as technical specifications, cooperation with a major local contractor can shorten the path to new customers and large-scale projects.
Beyond transformers to grid stability
AI data centers require more than large volumes of electricity. They need uninterrupted, high-quality power and a grid capable of maintaining stable voltage and frequency despite rapid changes in demand. As renewable energy occupies a larger share of the generation mix, power fluctuations increase, making precise grid-control systems more important.
Hyosung Heavy Industries has assembled a portfolio that extends beyond ultra-high-voltage transformers and gas-insulated switchgear. It includes static synchronous compensators, or STATCOMs, energy-storage systems and high-voltage direct-current transmission. The company was the first in South Korea to develop voltage-source HVDC technology based on a modular multilevel converter architecture and is advancing a 200-megawatt HVDC development project after completing a 30-megawatt medium-voltage direct-current installation.
This combination of technologies positions Hyosung Heavy Industries as more than a manufacturer of individual power components. Connecting AI data centers and renewable-generation facilities to transmission networks requires voltage conversion, power-quality management and grid control to operate together. Even after the current shortage of transformers begins to ease, demand for STATCOM, HVDC and digital asset-management systems is likely to continue as power grids become more complex.
A rapidly expanding order backlog does not automatically translate into immediate revenue. Ultra-high-voltage equipment takes considerable time to manufacture, transport and install, while quarterly earnings can fluctuate according to the timing of final customer delivery. In the second quarter, some US-bound products remained classified as goods in transit, while deliveries to the Middle East were delayed, leaving operating profit below market expectations.
The shortfall reflected the timing of revenue recognition rather than weaker demand. It nevertheless points to the next test for the company: managing working capital, delivery schedules and quality as production expands. The ability to convert a record backlog into predictable earnings will determine whether the current growth cycle produces durable improvements in corporate value.
Hyosung Heavy Industries’ recent performance reveals how the AI value chain is extending far beyond GPUs. As computing equipment proliferates, the physical constraints of electricity supply become more visible. Transformers, circuit breakers and grid-stabilization systems now influence when data centers can connect to the grid and begin operating.
Power equipment is no longer peripheral to AI investment. It is becoming infrastructure that determines the speed at which computing capacity can be deployed. With a substantial North American backlog, local manufacturing and ultra-high-voltage technology, Hyosung Heavy Industries is turning this structural bottleneck into measurable growth.
Its next phase will be judged by more than the size of its order book. The company must complete the Memphis expansion on schedule, convert its partnership with Quanta into production and project wins, and extend its position from transformer manufacturing to integrated grid solutions. The latest figures suggest that Hyosung Heavy Industries is building the foundation for structural growth—not merely benefiting from a temporary power-equipment boom.
