Hankook Steel

Hankook Steel, founded in 1987, is a specialized steel casting manufacturer that produces large, complex-shaped metal parts using a casting process in which molten metal is poured into molds.

The business is organized into a casting segment, a construction materials segment, and a scrap metal segment, with the casting segment forming the core of revenue.

Casting segment products span shipbuilding equipment such as rudder horns, stern bosses, propeller bosses and stern tubes, steelmaking equipment such as slag pots and ladles, industrial machinery parts including valve and pump castings, and casting products for cement and construction equipment.

The construction materials segment supplies bolted plate joints, composite pile head reinforcement steel pipe piles, and mechanical joints for reinforcing bars, linking its fortunes to the construction cycle.

The company is headquartered and operates a plant in Haman County, South Gyeongsang Province, with an additional plant in Uiryeong County.

Compared to large conglomerates focused on power generation equipment and offshore structures, the company is said to hold an upper-tier position domestically by specializing in medium-to-large steel castings.

Management has stated that large castings above 50 tons require substantial upfront investment, making new entry effectively impossible, and views the industry restructuring—as large firms scale back or outsource—as an opportunity.

Because shipyards place equipment orders roughly two years after securing their own vessel contracts, there is an inherent lag between a recovery in shipbuilding demand and its reflection in the company's casting revenue.

Consolidated revenue in 2025 was KRW 39.87bn, down about 15.7% from KRW 47.28bn in 2024, extending a three-year decline from KRW 53.81bn in 2023.

On profitability, 2025 saw an operating loss of KRW 176.7mn and a net loss attributable to owners of KRW 291.4mn, reversing from 2024's operating profit of KRW 1.07bn and net profit of KRW 762mn.

In 2023 the company posted its strongest recent-year result with operating profit of KRW 2.42bn (a 4.5% operating margin) and net profit of KRW 2.50bn, while 2022 showed an operating loss of KRW 517.7mn alongside a net profit of KRW 1.72bn, suggesting non-operating factors played a large role that year.

On a quarterly basis, Q2 2025 revenue was KRW 11.67bn with operating profit of KRW 354mn and net profit of KRW 247mn, but Q3 2025 revenue fell to KRW 9.78bn with an operating loss of KRW 327mn and a net loss of KRW 321mn.

Q4 2025 losses continued, with revenue of KRW 9.00bn, an operating loss of KRW 278mn, and a net loss of KRW 316mn.

Entering 2026, Q1 revenue was KRW 8.83bn with a small operating profit of KRW 59mn and net profit of KRW 14.7mn, and Q2 revenue rose to KRW 11.08bn with operating profit of KRW 153mn and net profit of KRW 130mn, widening the recovery.

Still, the trailing four-quarter (Q3 2025 to Q2 2026) net income attributable to owners remains negative at KRW -491.9mn, meaning two consecutive profitable quarters have not yet fully offset the prior two loss-making quarters.

Operating cash flow in 2025 remained positive at KRW 2.03bn despite the net loss, and the debt ratio has steadily declined from 61.4% in 2022 to 15.1% in 2025, indicating an improved financial structure.

South Korea's shipbuilding industry is described as heading toward the peak of a once-in-13-years supercycle in 2026, with 2025 characterized as a year of backlog accumulation on expectations, and 2026 as the phase where that backlog materializes into revenue and profit.

The combined Q1 2026 operating profit of the big three shipbuilders (HD Korea Shipbuilding & Offshore Engineering, Samsung Heavy Industries, and Hanwha Ocean) reportedly hit a record high, and all three maintained double-digit operating margins in Q2 as well.

Some analysis suggests this recovery warmth is spreading beyond the big three to equipment suppliers and mid-sized shipyards.

Separately, the broader domestic steel industry reported improved Q2 2026 results on demand recovery and higher selling prices, suggesting a more favorable environment for scrap and steel input costs.

The casting industry Hankook Steel operates in has high barriers to entry due to the large capital investment required, and the company notes that because shipyards place equipment orders roughly two years after securing their own vessel contracts, the effects of the shipbuilding supercycle flow through with a time lag.

Competitor Doosan Heavy Industries (now Doosan Enerbility) is said to focus mostly on power generation equipment, offshore structures, and stern parts, giving Hankook Steel's casting products a relatively stable domestic position by comparison.

However, the expanding low-cost competitiveness of Chinese shipyards and geopolitical variables affecting LNG carrier delivery slots are cited as downside risks for the entire upstream industry.

In an April 2026 report, the company stated that its order backlog had expanded 37% year-on-year to 6,440 tons, reflecting an order increase trend that has been building since the fourth quarter of the prior year.

CEO Ha Man-gyu explained that demand for high-value-added casting products is rising as vessel types upgrade toward LNG carriers, eco-friendly ships, and offshore plants, and stated that stable supply to major domestic shipyards should support continued volume growth.

The company indicated that higher volumes would improve production efficiency and translate into stronger profitability, and it also identified the power plant equipment segment as an additional growth driver.

The return to operating profit in both Q1 and Q2 2026 can be viewed as an early indication that the backlog expansion is beginning to feed through into results.

Industry-wide analysis suggests that as the share of dual-fuel engines and high-efficiency propulsion systems rises, profitability improvements for domestic equipment suppliers should accelerate, which could be interpreted as a favorable environment for shipbuilding equipment suppliers like Hankook Steel.

However, because this effect is structured to reach the company with a lag relative to the large shipbuilders, the pace and magnitude at which backlog growth translates into actual revenue and profit improvement will need further confirmation through upcoming quarterly results.
