POSCO will establish a wholly owned special purpose company, POS-Louisiana (tentative), in Delaware, which will be 100% owned after the transaction and will acquire a 20% stake in Hyundai Steel Louisiana LLC. The company’s total contribution is expected to be about USD 582 million (approximately KRW 858.6 billion, equal to 2.6% of equity capital and 1.7% of total assets based on the latest figures).

POSCO HOLDINGS INC. announced a change in how it determines which shareholders are entitled to receive year-end dividends for fiscal year 2025. Following a 2023 amendment to its Articles of Incorporation, the record date for year-end dividends is no longer automatically the last day of the fiscal year, but instead is a date set by a resolution of the Board of Directors.

For FY2025, the Board plans to determine the year-end dividend record date at a meeting in February 2026. Being listed as a shareholder on the last day of FY2025 will not, by itself, give the right to receive the year-end dividend. Only shareholders recorded on the company’s shareholder registry as of the specific year-end dividend record date for FY2025 will be eligible.

The record date for determining shareholders who can exercise voting rights at general meetings remains December 31, as set in the Articles of Incorporation. Whether dividends will be paid and the dividend amount will be decided at the Annual General Shareholders’ Meeting after the Board’s resolution.

The company indicates it plans to provide a further update with a re-disclosure date set for January 2, 2026, signaling that investors may receive more clarity then.
