HD Hyundai Marine Solution

HD Hyundai Marine Solution supplies parts, maintenance, retrofits and digital solutions across a vessel's life after delivery.

The business consists of four segments - AM Solution, bunkering, eco-friendly solutions and digital solutions - and on a 2025 basis the revenue mix was AM Solution 47%, bunkering 39%, eco-friendly 9% and digital 5%.

AM Solution covers supply of main and auxiliary engine parts, maintenance, repair and service, plus warranty agency work for vessels built by the group.

Bunkering supplies fuel required when newly built group vessels depart on delivery, purchased from refining affiliate HD Hyundai Oilbank, and while its revenue contribution is large, low profitability means earnings hinge on the AM, eco-friendly and digital segments. The customer base is not limited to group volumes.

The company is broadening service coverage beyond vessels built by HD Hyundai shipbuilding affiliates to ships built by other yards. Digital solutions handle integrated vessel control systems and smart-ship installations, and the company runs a control center that upgrades voyage-data based services.

Competition is twofold: non-genuine parts suppliers in the aftermarket, and global engine and generator makers in the newly entered power-engine service market. In data-center power generation, global players such as Caterpillar and Cummins have already been expanding supply of large engines and generators.

Annual results expanded from 2023 revenue of KRW 1,430.5bn and operating profit of KRW 201.5bn to KRW 1,745.5bn and KRW 271.7bn in 2024, then KRW 1,982.7bn and KRW 350.1bn in 2025.

Operating margin rose for three consecutive years from 14.1% to 15.6% and 17.7%, while net profit attributable to owners grew from KRW 151.1bn to KRW 227.9bn and KRW 269.6bn.

Operating cash flow improved from KRW 72.9bn in 2023 to KRW 246.5bn in 2024 and KRW 324.1bn in 2025, supporting cash conversion, while the debt-to-equity ratio fell sharply from 173.6% in 2023 to 49.0% in 2024 and 54.3% in 2025 (equity of KRW 824.7bn at end-2025).

Quarterly, revenue rose consecutively: KRW 467.7bn with KRW 83.0bn operating profit in 2Q25, KRW 513.2bn and KRW 93.6bn in 3Q25, KRW 516.2bn and KRW 90.5bn in 4Q25, KRW 574.6bn and KRW 93.4bn in 1Q26, and KRW 580.4bn and KRW 97.6bn in 2Q26.

Quarterly operating margin, however, eased from 18.2% in 3Q25 to 17.5%, 16.3% and 16.8%, and Samsung Securities has noted that high-margin bulk sales concentrated in particular quarters shift the base, and that quarterly earnings swings are a feature of the business.

The composition of growth is visible in company disclosure. In 2Q26 AM revenue rose 19.6% to KRW 275.0bn, helped by a strong newbuild market plus onshore power generation and an Ecuador maintenance contract, while parts shipments topped 60,000 a month, about 27% above the prior-year monthly average.

In the same quarter eco-friendly solutions posted KRW 45.3bn (up 38.1%) and digital solutions KRW 36.4bn (up 65.5%). Summing the latest four quarters (3Q25-2Q26) gives revenue of KRW 2,184.4bn, operating profit of KRW 375.1bn and owners' net profit of KRW 334.4bn, an operating margin of roughly 17.2%.

Bottom-line volatility also deserves note: 1Q26 owners' net profit of KRW 98.1bn exceeded that quarter's operating profit of KRW 93.4bn, and 2Q26 pre-tax profit from continuing operations was KRW 108.9bn, up 59.4% year on year but down 8.9% from KRW 119.5bn in the prior quarter, implying non-operating contributions varied by quarter.

The end market here is not newbuild orders but the fleet in operation. As deliveries rise, the serviceable fleet accumulates, so the shipbuilding upturn feeds through over the years after delivery.

As of 2Q26, cumulative vessels served under AM reached 10,168, and this installed base effectively sets the scale of the business. The regulatory backdrop is layered.

The EU Emissions Trading System has covered shipping since 2024, charging 100% of emissions on intra-EU voyages and at berth and 50% on EU-to-non-EU routes, while FuelEU Maritime took effect in January 2025 and tightens greenhouse gas intensity standards in stages. The global pillar, by contrast, has slipped.

The IMO Net-Zero Framework, combining technical measures with a carbon levy, was originally slated for adoption in October 2025 but opposition from some states pushed the adoption debate to October 2026.

DNV has said some operators may turn cautious amid regulatory uncertainty, but the broad direction of shipping decarbonization has not materially changed and commercial drivers remain intact. A new demand axis has also emerged in data-center power.

Wood Mackenzie projected US data-center capacity rising from about 24GW in 2026 to 110GW by 2030. In competitive terms, the company is trying to extend vessel maintenance capability into onshore and offshore power equipment service, a market where global power-equipment suppliers are already entrenched.

The company's disclosed mid-term targets form a checkable baseline.

In the value-up plan released in March 2026, it set a 20% average annual growth rate for core-business revenue through 2028, a 20% company-wide operating margin by 2028, a payout ratio of 50-70% of separate-basis net profit for the next three years with quarterly dividends four times a year, and a corporate governance report compliance rate above 90% in 2026.

Business focus is shifting from first-generation retrofits to fuel-conversion work.

The company said it will wind down first-generation retrofit work in stages and expand into next-generation conversions for green fuels such as methanol and ammonia and for carbon reduction, aiming to capture global gas-carrier retrofit demand. The new axis is data-center servicing.

In May 2026 it signed an MOU with US-based AEG on maintenance of data-center power engines, setting up long-term maintenance and operation cooperation for 33 engines at a Texas data center, and explained that the tie-up presumes long-term service agreements (LTSA) and operations and maintenance (O&M) contracts.

Group-level volumes provide the backdrop. HD Hyundai Heavy Industries' cumulative first-half 2026 orders for data-center medium-speed engines reached about KRW 1,580bn, including KRW 627.1bn with AEG in April and a subsequent KRW 956.0bn contract with Corban Energy Group.

Under the structure, HD Hyundai Heavy Industries supplies engines while HD Hyundai Marine Solution handles after-service, and the maintenance interval for data-center power engines is estimated at about three years versus roughly five for marine engines.

Still, the timing and scale of revenue recognition from these agreements are not yet fixed in disclosures, and eco-retrofit demand may hinge on the outcome of the October 2026 regulatory debate.
