On confirmed numbers, 2022 revenue was KRW 4,671.3bn with operating profit of KRW 976.7bn (20.9% margin) and 2023 revenue KRW 2,649.7bn with operating profit of KRW 531.2bn (20.0%), two straight years of roughly 20% margins.
The sharp 2023 revenue decline, however, mixes in the spin-off and changes in consolidation scope, so it is not directly comparable with 2022.
In 2024 revenue rose to KRW 3,577.4bn but operating profit collapsed to KRW 101.5bn (2.8%), and in 2025 revenue of KRW 3,380.1bn came with an operating loss of KRW 57.6bn and an owners' net loss of KRW 89.9bn.
Operating cash flow in 2025 was an inflow of KRW 553.9bn versus KRW 116.4bn in 2024, so weak accounting profit did not translate into cash drain.
Quarterly, the operating loss narrowed from KRW 80.3bn in the second quarter of 2025 to KRW 53.3bn in the third, then turned to profits of KRW 27.3bn in the fourth quarter, KRW 10.9bn in the first quarter of 2026 and KRW 108.1bn in the second, three consecutive quarters in the black.
Revenue also expanded for five straight quarters from KRW 776.2bn in the second quarter of 2025 to KRW 1,023.2bn in the second quarter of 2026, lifting the latter quarter's operating margin above 10%.
The thin first-quarter 2026 profit was attributed to lower utilization during the Malaysian polysilicon unit's 15-month scheduled maintenance plus KRW 13bn of inventory valuation losses, while in the second quarter TerraSus completed maintenance and returned to normal operation, cutting its operating loss from KRW 27bn in the prior quarter to KRW 3bn.
Owners' net profit of KRW 48.3bn in the second quarter lagged operating profit by a wide margin, reflecting minority interests plus financing and tax costs, consistent with non-controlling equity rising from KRW 93.8bn in 2023 to KRW 856.3bn in 2024.
On balance-sheet strength, the debt-to-equity ratio was 68.2% in 2022, 56.1% in 2023, 67.4% in 2024 and 66.3% in 2025, held in the 60% range.
