Hanyang Eng company operations generate revenue through a mix of high-growth High-Tech Facility projects, stable General Plant work, and an expanding Maintenance and Service segment that together balance cyclical and recurring income streams.

High-Tech Facility Division

The High-Tech Facility Division is the primary revenue driver, producing approximately 78 percent of total revenue in fiscal 2025 through EPC contracts for semiconductor and display cleanrooms.

General Plant Division

The General Plant Division contributed about 14 percent in 2025, focused on power generation, environmental infrastructure, and gas facilities that reduce sensitivity to semiconductor cycles.

Maintenance and Service

Maintenance and Service now represents 8 percent of revenue, driven by multi-year recurring contracts to operate and optimize chemical supply systems installed by the firm.

Geographic Diversification

International expansion shifted the mix toward North America, which accounted for 22 percent of revenue in 2025, up from 15 percent in 2023, supporting revenue stability.

Pricing and Billing Models

Tiered pricing for specialized engineering consulting and progress-based billing on long-term construction projects ensure steady cash flow across project lifecycles.

Strategic Growth Focus

Management targets growth in recurring-services and international EPC work to lift the share of stable, service-based revenue over the next three years.

Revenue Structure Highlights

Key elements of the Hanyang Engineering business model and how Hanyang Eng functions commercially.

• High-Tech Facility EPC projects drive top-line growth and account for 78 percent of 2025 revenue.
• General Plant projects provide stable, counter-cyclical revenue at 14 percent.
• Maintenance and Service offers recurring revenue, totaling 8 percent in 2025 via multi-year contracts.
• North American revenue share increased to 22 percent in 2025, reflecting successful international project execution and pricing strategies.

Hanyang Eng holds a top-three global position in the CCSS market and is the dominant domestic contractor in South Korea, with a record order backlog of 920 billion KRW entering 2026. The firm’s global operations span China, Vietnam, and the United States, while risks include client concentration, semiconductor cyclicality, and tightening environmental regulations.

Market Position

Hanyang Eng company operations secure a top-three share in the global CCSS market and lead in South Korea. Geographic expansion into China, Vietnam, and the US supports diversified project pipelines.

Order Backlog

The company reported a record-high order backlog of 920 billion KRW entering 2026, underpinning near-term revenue visibility for EPC and CCSS contracts.

Key Risks

High client concentration and exposure to the cyclical semiconductor industry create revenue volatility. Regulatory tightening on chemical handling increases compliance and capex needs for waste treatment and emission control.

Strategic Pivot

Leadership has prioritized a Green EPC roadmap—hydrogen refueling stations, industrial water recycling, and ESG-aligned projects—to diversify revenue and reduce dependence on semiconductor cycles.

Technology and operational upgrades are central to future margins: automation and robotics, combined with advanced waste-treatment R&D, will be deployed alongside continued CCSS delivery.

Future Outlook & Execution Priorities

Hanyang Eng’s roadmap targets revenue diversification and productivity gains through Green EPC, automation, and sustainable infrastructure projects aligned with global ESG demand.

• Target integration of automated robotic installation by 2027
• Develop hydrogen refueling stations and advanced industrial water recycling systems
• Invest in emission-control and waste-treatment technologies to meet evolving regulations
• Leverage AI-driven hardware demand to sustain CCSS project pipelines
