The Notes section does not present a standard balance sheet or liquidity table. The filing date is 2026-04-29, and the entity is a Korean foreign private issuer (20-F). The only quantitative balance-sheet-related figure explicitly stated is the total contractual payment obligations due in 2026, which amount to Won 2,350.2 billion. This figure excludes short-term leases and leases of low-value assets and is primarily composed of debt repayments and lease liabilities. The document also references the cybersecurity incident fine of Won 134.8 billion imposed by the PIPC on August 27, 2025, which the company provisionally paid in full and is contesting via an administrative lawsuit filed in January 2026.
The company disclosed total contractual payment obligations of Won 2,350.2 billion as of December 31, 2025, due within 2026. These obligations are mostly related to debt repayments and lease liabilities. Additionally, the company has entered into significant capital expenditure commitments, including the construction of an AI data center in Ulsan (partnership with AWS, operations expected in 2027) and a letter of intent with OpenAI for the Stargate project. The company also made equity investments of US$200 million in Penguin Solutions Inc. in December 2024 and US$20 million in Lambda, Inc. in February 2024. The pending divestiture of SK Stoa and Media S to Rapport Labs Inc. also represents a future commitment.
Capital expenditures for 2025 were Won 2,206.6 billion. The company states it expects a slightly higher amount for 2026, focused on network maintenance, AI infrastructure, and data center investments. No specific buyback or dividend figures are disclosed in the provided Notes section excerpt. The company's debt instruments contain financial covenants (maximum net debt-to-EBITDA of 3.50, minimum EBITDA-to-total interest expense ratio of 4.00). The cybersecurity incident led to a temporary suspension of new mobile subscriptions (May-June 2025) and a waiver of cancellation fees, along with approximately Won 500 billion in customer appreciation benefits in the second half of 2025.
