In particular, its petroleum business is based on stable crude oil procurement capabilities and refining technology, while its lubricants business is solidifying its technology-driven market competitiveness and global presence. The battery business is strengthening its competitiveness by securing production bases in various parts of the world, including the US, Europe, and China, based on high energy density and high-output technologies. It also aims to become a global LNG player by successfully establishing an LNG value chain for the first time among private companies in South Korea. Furthermore, it possesses world-class technological capabilities in the field of lithium-ion battery separators (LiBS), a key material for secondary batteries. SK Innovation's annual revenue decreased by approximately 1.67% from KRW 78.0569 trillion in 2022 to KRW 76.7557 trillion in 2023, and further decreased by approximately 3.24% to KRW 74.2696 trillion in 2024. However, in 2025, revenue recorded KRW 80.2961 trillion, an increase of approximately 8.11% year-over-year, marking a shift to revenue growth. Operating income sharply declined by approximately 52.01% from KRW 3.9173 trillion in 2022 to KRW 1.8806 trillion in 2023, and further decreased by approximately 81.08% to KRW 355.7 billion in 2024, indicating a significant deterioration in profitability. In 2025, operating income slightly improved to KRW 448.7 billion, an increase of approximately 26.15% year-over-year, but remains at a lower level compared to 2022. The operating profit margin declined from approximately 5.02% in 2022 to approximately 0.48% in 2024, then slightly increased to approximately 0.56% in 2025. In 2025, the company recorded a net loss of KRW 5.4 trillion due to the recognition of a large-scale asset impairment loss. Examining SK Innovation's financial soundness, the debt-to-equity ratio improved from 189.21% in 2022 to 169.27% in 2023, but then rose again to 178.77% in 2024 and 190.20% in 2025, maintaining a high level. The current ratio was 116.00% in 2022 and 113.20% in 2023, but it fell below 100% to 96.27% in 2024, indicating a somewhat weakened ability to repay short-term debt. In 2025, it slightly improved to 104.23% but is still not at a stable level. The Return on Equity (ROE) was 8.15% in 2022, but data for 2023 to 2025 was not provided. However, considering the large net loss recorded in 2025, ROE is estimated to have been negative. In line with industry trends of eco-friendly energy transition and the expansion of the EV and ESS markets, SK Innovation is pursuing the expansion of its business model to become an "electricity provider." To achieve this, the company is focusing on expanding its global LNG value chain and diversifying its ESS business portfolio, while planning to secure future growth engines by strengthening the fundamentals of its battery business and expanding production capacity. Furthermore, it is striving to stabilize its financial structure through the sale of non-core assets and business restructuring, and is also making efforts to achieve carbon neutrality goals, including exploring Carbon Capture and Storage (CCS) projects.
