Youngpoong

Founded in 1949, Yungpoong is an integrated non-ferrous metal smelting company operating a smelting division at the Seokpo smelter in Bonghwa, North Gyeongsang Province, producing zinc ingots and by-product sulfuric acid, alongside an electronics division comprising PCB and FPCB affiliates such as Korea Circuit, Interflex, Yungpoong Electronics and Teranix, plus semiconductor packaging firm Signetics.

Zinc is used mainly as a plating raw material to prevent corrosion in steel products, while the electronics division supplies HDI boards for smartphones and memory module PCBs to leading global companies.

Korea Circuit counts Samsung Electronics and Samsung Display among its customers and has been restructuring toward higher value-added PCBs such as FC-BGA, while Interflex and Yungpoong Electronics mainly produce flexible printed circuit boards (FPCB) for smartphones and displays.

Signetics is a semiconductor packaging company whose main clients include Samsung Electronics and SK Hynix.

The smelting division imports zinc concentrate from overseas, transporting it via Donghae Port and then by rail or truck to the smelter, and its location away from ports or industrial complexes is viewed as a relative logistics cost disadvantage.

Through its affiliate structure, Yungpoong holds a stake in Korea Zinc, and the two companies have historically run parallel non-ferrous metal operations, though Yungpoong is now also positioned as one side of a governance dispute over control of Korea Zinc.

The company is reported to hold a substantial share of the domestic and overseas zinc markets, though industry observers note that the single-smelter, zinc-centered product portfolio at Seokpo is relatively less diversified compared with Korea Zinc's Onsan smelter.

Consolidated revenue declined from KRW 4,429.5bn in 2022 to KRW 3,761.7bn in 2023 and KRW 2,787.4bn in 2024, before recovering to KRW 2,909.0bn in 2025.

Operating profit, which had been positive at KRW 68.9bn in 2022, turned negative for three consecutive years at KRW -169.8bn in 2023, KRW -160.7bn in 2024 and KRW -259.7bn in 2025, while net income attributable to owners similarly weakened from KRW 367.2bn in 2022 to KRW -60.9bn, KRW -252.1bn and KRW -8.3bn respectively, largely reflecting production disruptions including a suspension at the Seokpo smelter in 2025.

On a quarterly basis, losses persisted in Q3 2025 (revenue KRW 749.6bn, operating profit KRW -8.8bn) and Q4 2025 (revenue KRW 987.7bn, operating profit KRW -100.5bn), before Q1 2026 turned profitable with revenue of KRW 851.1bn and operating profit of KRW 43.3bn, with owners' net income of a modest KRW 0.85bn.

Q2 2026 maintained profitability with revenue of KRW 853.2bn and operating profit of KRW 1.5bn, though the profit size shrank considerably from the prior quarter, while owners' net income expanded sharply to KRW 377.0bn, a figure that appears to reflect substantial non-operating items.

Summing the most recent four quarters (Q3 2025 through Q2 2026), owners' net income totaled KRW 105.3bn, marking a departure from the large losses of 2023-2024.

However, the fact that Q2 operating profit was only about 3% of Q1's level suggests that gains from higher zinc and sulfuric acid prices were partly offset by the fire-related shutdown of the No.6 roasting process and the resulting utilization decline (from 57.23% in Q1 to 51.7% in Q2).

The debt ratio rose somewhat from 33.4% in 2022 to 49.4% in 2025, though the absolute level remains within a manageable range.

The global zinc market has tightened through 2026 as mine supply disruptions accumulated, pushing treatment charges (TC/RC) to record-low negotiated levels and squeezing smelter margins.

Wood Mackenzie widened its forecast for this year's global zinc supply deficit from 80,000 tons to roughly 200,000 tons, citing downward production revisions concentrated among Chinese smelters whose profitability has deteriorated under low treatment charges.

LME zinc inventories have stayed at low levels for much of the year, repeatedly producing backwardation in spot premiums, and the average domestic Korean zinc ingot price rose to about KRW 5.17 million per ton in the first half.

Some market participants nonetheless note that prices could stabilize gradually if Chinese zinc exports expand alongside a recovery in mine supply.

On the downstream electronics side, demand for AI server and DDR5 memory module replacement, along with higher-specification main PCBs for 5G smartphones, has supported order volumes at affiliates such as Korea Circuit and Interflex.

Rival Korea Zinc kept its Onsan smelter utilization at 100% in the first half and posted record results, presenting a contrast with the single-smelter, zinc-centric Seokpo operation in terms of product diversification and facility stability.

In the near term, the pace of repairs to the No.6 roasting process halted by the July fire, and the resulting recovery in Q3 utilization, are likely to be the key variables for results.

The labor union has indicated that follow-on processes such as leaching and electrolysis may also need adjustment as a result of the No.6 shutdown, raising the possibility of wider production disruption if repairs are prolonged.

On the environmental front, the government (Ministry of Climate, Energy and Environment) is conducting a detailed site investigation into impacts on the Nakdong River drinking water source, and has told the National Assembly that strong administrative measures, including a possible operation suspension, could be considered depending on the findings.

The outcome of the administrative lawsuit over the roughly KRW 20.47bn Securities and Futures Commission penalty, and progress on a related criminal complaint that the Seoul Metropolitan Police Agency's investigation review committee decided to reinvestigate, are also variables to monitor.

On the governance side, the outcome of the vote contest over a separately elected audit committee seat at Korea Zinc's September 9 extraordinary general meeting could affect the checking power the Yungpoong-MBK alliance holds on the board.

In electronics, industry observers expect continued improvement in PCB profitability driven by AI server and DDR5 replacement demand and higher-specification 5G smartphones, and the payoff from Korea Circuit's investment in higher value-added PCBs such as FC-BGA also warrants ongoing monitoring.
