6. Other important details to be considered for investment decisions	1. Because we qualify as a high-dividend company that disclosed its corporate value-up plan prior to the date on which Article 104-24 of the Enforcement Decree of the Act on Restriction of Special Taxation became effective, we hereby redisclose “2024 POSCO Holdings Corporate Value-up Plan,” previously filed on December 23, 2024. Additionally, the implementation evaluation for the corporate value-up plan will be disclosed in the latter half of this year.” 2. Item 3 pertains to the qualification of high-dividend company as defined by Article 104-27 of the Act on Restriction of Special Taxation. Based on the interpretation of the statute by relevant authorities, “immediate preceding business year” that appears in Paragraph 1 Subparagraph 2 of the Article refers to the business year immediately preceding the most recent business year. By this definition, we provide that the Company’s dividend income in the immediate preceding business year (2024) did not decrease against the base year (2024). Therefore, the Company qualifies as a high-dividend company.



		3. The dividend per share for 2024 and 2025 remains unchanged at KRW 10,000. However, the amount of dividend for 2025 is lower than that of 2024, due to a reduction in the number of outstanding shares (a decrease of 255,428 shares) following the acquisition and subsequent cancellation of treasury shares in August 2024. 4. Item “4. Date of Decision” refers to the date of the Annual General Shareholders’ Meeting. 5. For more details, please refer to the attached “2024 POSCO Holdings Corporate Value-up Plan”. 6. This disclosure material includes plans and forecast information, and it may be subject to change depending on future market conditions and changes in the business environment.
