Geumhwa Psc

Geumhwa PSC is a specialized plant construction company founded in May 1981, which became the first private company to enter the power plant maintenance business in 1995, evolving into a comprehensive plant specialist spanning plant construction to power plant maintenance management.

The business is broadly divided into power plant maintenance and plant construction segments.

The maintenance segment tracks operating conditions of active power generation facilities and provides routine inspections to maintain optimal operating status, performing regular and planned preventive maintenance, commissioning support, and desulfurization facility operation.

The plant construction segment handles mechanical, piping, and steel structure installation work for domestic and overseas thermal, nuclear, and combined-cycle power plants, and also participates in petrochemical, LNG, steel, and environmental facility construction.

The company further diversified its portfolio by expanding into water treatment services following a contract with Ecobit in 2022.

The power plant maintenance market is dominated by a small number of specialized firms with accumulated facility expertise and certifications such as KEPIC, while in plant construction the company typically participates as a subcontractor or partner to large EPC main contractors such as Hyundai Engineering & Construction and Doosan Enerbility.

Indeed, in the Shin-Hanul Units 3&4 main construction project, the company secured detailed construction work as a subcontractor to main contractor Hyundai Engineering & Construction.

Drawing on its experience in domestic and overseas power plant maintenance, the company contributes to preventing unplanned outages and rapid fault recovery, building a stable revenue base in a business area with a public-utility character tied to reliable power supply.

2025 consolidated revenue reached KRW 423.4bn, up 24.5% from KRW 340.2bn in 2024, extending a four-year growth streak following KRW 248.3bn in 2022 and KRW 337.6bn in 2023.

However, operating profit of KRW 43.8bn did not grow proportionally with revenue, and the operating margin fell to 10.3%, down from 10.6% in 2024 and 12.9% in 2023.

Net profit attributable to owners actually declined to KRW 30.6bn in 2025 from KRW 40.0bn in 2024 and KRW 38.0bn in 2023, showing profitability failing to keep pace with revenue growth.

On a quarterly basis, 2Q25 posted strong results with revenue of KRW 110.6bn and operating profit of KRW 18.3bn, before sharply slowing to revenue of KRW 93.8bn and operating profit of KRW 3.8bn in 3Q25, then recovering to revenue of KRW 132.1bn and operating profit of KRW 15.5bn in 4Q25 — a pattern reflecting seasonality tied to construction progress and completion timing.

Entering 2026, 1Q26 contracted sharply to revenue of KRW 84.9bn and operating profit of just KRW 1.28bn, before rebounding strongly in 2Q26 to revenue of KRW 137.0bn, operating profit of KRW 16.8bn, and owner net profit of KRW 14.2bn.

The trailing four-quarter (3Q25–2Q26) sum of owner net profit stands at roughly KRW 30.0bn, serving as a reference point for gauging the annual earnings trajectory.

Notably, 2025 operating cash flow was negative at KRW -24.7bn, moving in the opposite direction from net profit — a sharp contrast to the positive KRW 74.6bn in 2024 and KRW 40.2bn in 2023.

This divergence between cash flow and net profit may stem from changes in construction-in-progress items such as unbilled receivables tied to large project completion rates, warranting continued monitoring of cash flow trends in future earnings releases.

The power plant maintenance business is reportedly shifting toward requiring superior technical capability and higher-quality service amid decarbonization policy and renewable energy expansion, while the water treatment industry appears to be seeing improved results driven by stricter environmental regulations and rising water quality requirements.

Under Korea's 11th Basic Plan for Electricity Supply and Demand, growth is projected to center on renewables along with LNG, hydrogen, and nuclear power, a shift that could reshape the traditionally thermal-power-centered maintenance market structure.

Indeed, amid government policy to restore the domestic nuclear power ecosystem, large-scale nuclear construction projects such as Shin-Hanul Units 3&4 have resumed, creating a long-term revenue channel for specialized construction firms like Geumhwa PSC that participate as subcontractors under major main contractors.

However, downstream demand for power plant maintenance and construction is heavily influenced by government energy policy direction and plant commissioning and operation schedules, meaning order volumes can fluctuate with policy shifts.

In terms of competitive structure, the maintenance segment is dominated by a small number of specialized, certified firms, while the plant construction segment features a multi-tiered structure in which large EPC contractors such as Hyundai Engineering & Construction, Doosan Enerbility, Samsung C&T, and Daewoo E&C serve as main contractors with numerous specialized firms participating as subcontractors.

Within this landscape, Geumhwa PSC appears to be pursuing a diversified business model spanning maintenance, plant construction, and water treatment, seemingly aimed at reducing dependence on any single power source or client.

The most concretely confirmed medium-to-long-term revenue base is the Shin-Hanul Units 3&4 main construction subcontract secured from Hyundai Engineering & Construction, disclosed at a contract value of KRW 42.4bn with a contract term running through December 31, 2030.

The supply area is in Buk-myeon, Uljin County, North Gyeongsang Province, and the contract value represented 12.56% of the company's revenue in the year prior to disclosure. Through this contract, the company has secured a stable revenue recognition window in the nuclear construction segment for the coming years.

The government's policy to restore the nuclear power ecosystem and the 11th Basic Plan for Electricity Supply and Demand's focus on renewables, LNG, hydrogen, and nuclear investment are cited as factors that could provide a favorable policy environment for both the maintenance and plant construction segments.

However, as seen in 1Q26, a slowdown in construction progress in a given quarter can sharply compress results, meaning the pace of new orders and progress on existing projects will likely remain a key variable for future revenue and profit recognition.

The water treatment segment is also mentioned as an area of gradual growth amid tightening environmental regulation, though specific new orders or capacity expansion plans would need to be confirmed through further disclosures.
