2. Business Status of Segments

A. Steel

There are 85 consolidated companies in the steel segment, e.g., POSCO, POSCO STEELEON, and overseas subsidiaries, including PT.Krakatau POSCO in Indonesia, POSCO (Zhangjiagang) Stainless Steel Co., Ltd. in China, and overseas processing centers.

∎POSCO

(1) Summary of Business

POSCO produces steel components, such as hot rolled, cold rolled, and stainless steel, at Pohang Steelworks and Gwangyang Steelworks, of which latter is the largest in the world.

Steel is a key industry that has served a pivotal role in achieving national economic development. Steel is used as a basic material in diverse manufacturing businesses, such as automobiles, shipbuilding, home appliances, and construction; therefore, steel, by its nature, is intricately connected to the frontline industries.

In the first half of 2025, global crude steel production posted a moderate year-on-year decline, despite continued demand from emerging economies, such as India. The slowdown is attributed to the global uncertainties driven by U.S. tariffs and sluggish demand in key industries, including China’s housing sector.

The steel industry is affected by the business cycle and fluctuations in the demand industry.

Therefore, steel demand is impacted by changes in the real economy as well as market conditions of demand industries, i.e., shipbuilding, automobiles, home appliance, and construction.

The steel industry is a capital- and technology-intensive industry that requires massive initial investment. Hence, steelmakers are focused on reducing production costs to achieve price competitiveness.

POSCO aims to maintain its competitive edge in the domestic market by strengthening long-term partnership with key customers and by devising comprehensive responses, such as marketing, R&D, technology services, and productions, to address global protectionism. In addition, we are expanding steel processing centers to meet the needs of global frontline industries, such as automobiles, shipbuilding, home appliances, and construction, while strengthening our global sales network by operating steel production bases in Indonesia (upstream) and India (cold-rolling mills). Additionally, we are seeking opportunities to expand overseas production capacity; one such example is the JV project completed with Hebei Steel in 2023.

On the production side, we are developing strategic, high value-added World Top Premium products and upgrading sales network to respond to the growing demand for next-generation, carbon-reduced steel to actively respond to the growing demand for next-generation, carbon-reduced steel in new mobility, low-carbon energy, and smart infrastructure. Furthermore, we aim to lead the global initiative to achieve carbon net-zero; hence we have developed a decarbonization roadmap, which includes the construction of a HyREX (hydrogen-based steelmaking) technology demo plant.

The steel industry’s major demand sectors include automobiles, shipbuilding, and construction, in which steel is a key raw material. The company’s sales consists of approximately 52% domestic sales and 48% exports, with Japan, Europe, and Southeast Asia accounting for a significant portion of exports. We maintain a make-to-order production and sales system while keeping the proportion of direct sales to end-users in the domestic market at around 61% to secure sales stability.

The company has established a mid- to long-term roadmap to achieve net zero emissions by 2050. We are developing technologies to reduce carbon emissions in existing processes, introducing large-scale electric furnaces, and pursuing a phased transition of facilities and processes that includes commercialization of the HyREX (hydrogen-based steelmaking) process. At the same time, we are focusing company-wide efforts on securing a stable supply of carbon-reduced raw materials such as scrap and HBI. From 2026, we plan to produce carbon-reduced, high value-added products using electric furnaces.

Building on the expertise we accumulated on building and operating a Smart Factory since 2017, we are accelerating the implementation of the Intelligent Factory that connects all areas of business, from production, logistics, to office operations, with the Digital Twin technology.

Safety is our top priority and a core value of our corporate culture. We are reinforcing safety by identifying potential hazards in the workplace and ensuring compliance to safety standards, while also developing smart safety solutions utilizing AI and IoT technologies.

Even though POSCO is an unlisted company and therefore does not have any obligation to establish a special committee under the board of directors, we have created an ESG committee to strengthen our external communication with interested parties. Furthermore, we have also established an audit committee to support ESG governance. As a result, the company has been named Sustainability Champion by the World Steel Association — an honor awarded to leading companies in the ESG field — for four consecutive years.

∎POSCO STEELEON

POSCO STEELEON offers differentiated value by developing new market and technology and by providing designs and solutions in both domestic and overseas surface-treated steel market.

The surface-treated steel market is divided into general-purpose and high-end segments. Competition is fierce in the general-purpose market because product technology is standardized and the market is flooded with low-priced Chinese products. On the other hand, we believe that the market for high-end material not only generates high added value but also has potential to grow in terms of size.

Despite challenges posed by oversupply of domestic and foreign steel products and slowdown in demand industries, POSCO STEELEON is striving to secure a stable profit base and expand market share by improving the competitiveness of high valued-added products, such as aluminum coated sheets, galvanized steel sheets with high corrosion resistance, and Print/Lami color steel sheets.

POSCO STEELEON is striving to strengthen its competitiveness in the high-end construction/exterior materials through research and development customized to customer needs. In addition, POSCO STEELEON is preparing to expand its overseas business; the company operates a color steel sheet production line (50,000 ton) and coated steel sheet production line (20,000 ton) in Yangon, Myanmar, securing a bridgehead in Southeast Asia, a region projected for rapid growth.

∎POSCO M-TECH

(1) Summary of Business

POSCO M-TECH is a specialized supplier of packaging and supplementary materials for steel. This includes aluminum deoxidizers, which removes oversaturated oxygen in the steelmaking process. POSCO M-TECH continuously develops packaging machines and materials for steel products. The steel packaging business has enhanced cost competitiveness by reducing packaging materials and improving packaging quality, while the packaging equipment business has focused on developing automated equipment.

[Energy Materials]

In order to leap forward as an energy materials company, POSCO Future M acquired the anode materials division of LS Mtron in August 2010 and merged with the cathode materials company POSCO ESM in April 2019. POSCO Future M produces both anode active materials (anode materials) and cathode active materials (cathode materials), which are high-value-added materials in the rechargeable battery value chain.

As an integral part of POSCO Group, POSCO Future M has established a full battery materials value chain, ranging from raw to active battery materials and battery recycling. It is the only company to produce graphite-based anode materials, a critical mineral predominated by China. Therefore, the company expects sales to increase in the future by supplying global automakers and battery makers that seek to decouple from China.

However, if POSCO Group’s production of raw materials, such as lithium, nickel, and graphite, declines or is delayed against the plan or if we are unable to meet the stricter Rules of Origin guidelines, we may not be able to reap all of the projected benefits.

D. Others

In Others segment, there are 16 subsidiaries in total, including POSCO HOLDINGS. POSCO HOLDINGS focuses on investing in new growth businesses and opportunities.

Report on review of interim condensed consolidated financial statements

(English translation of a report originally issued in Korean)

The Stockholders and Board of Directors

POSCO HOLDINGS INC.

We have reviewed the accompanying interim condensed consolidated financial statements of POSCO HOLDINGS INC. and its subsidiaries (collectively referred to as the “Group”), which comprise the interim condensed consolidated statement of financial position as of June 30, 2025, and the related interim condensed consolidated statements of comprehensive income or loss for each of the three-month and six-month periods ended June 30, 2025 and 2024, interim condensed consolidated statements of changes in equity and interim condensed consolidated statements of cash flows for each of the six-month periods ended June 30, 2025 and 2024, and a summary of material accounting policy information and other explanatory information.

Management’s responsibility for the interim condensed consolidated financial statements

Management is responsible for the preparation and presentation of these interim condensed consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”) 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express a conclusion on these interim condensed consolidated financial statements based on our review.

We conducted our review in accordance with the Review Standards for Quarterly and Semiannual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing (“KSA”) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim condensed consolidated financial statements are not prepared, in all material respects, in accordance with KIFRS 1034 Interim Financial Reporting.

Other matters

We have audited the consolidated statement of financial position of the Group as of December 31, 2024, and the related consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended (not presented herein) in accordance with KSA, and our report dated March 12, 2025 expressed an unqualified opinion thereon. The accompanying consolidated statement of financial position as of December 31, 2024, presented for comparative purposes, is not different, in all material respects, from the above audited consolidated statement of financial position.

August 14, 2025

This review report is effective as of August 14, 2025, the independent auditor’s review report date. Accordingly, certain material subsequent events or circumstances may have occurred during the period from the date of the independent auditor’s review report to the time this review report is used. Such events and circumstances could significantly affect the accompanying interim condensed consolidated financial statements and may result in modification to this review report.

2. Basis of Preparation

Statement of compliance

The interim condensed consolidated financial statements have been prepared in accordance with KIFRS 1034 Interim Financial Reporting, as prescribed in the Act on External Audit of Stock Companies of the Republic of Korea. The accompanying interim condensed consolidated financial statements have been translated into English from the Korean language financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s review report thereon, the Korean version, which is used for regulatory reporting purposes, shall prevail.

The interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Group’s annual financial statements as of December 31, 2024. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Group incurred after December 31, 2024.

Notes to the interim condensed consolidated financial statements, continued

June 30, 2025 and 2024 (Unaudited)

2. Basis of Preparation (cont’d)

These interim condensed consolidated financial statements do not include all of the disclosures required for full annual financial statements.

Use of estimates and judgments

(a)	Judgments, assumptions and estimation uncertainties

The preparation of the interim condensed consolidated financial statements in conformity with KIFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period prospectively.

(b)	Measurement of fair value

The Group’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Group has an established control framework with respect to the measurement of fair values. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values, and reports directly to the financial officer.

The valuation team regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of KIFRS including the level in the fair value hierarchy in which such valuation techniques should be classified.

Significant valuation issues are reported to the Group’s Audit Committee.

When measuring the fair value of an asset or a liability, the Group uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows.

•	Level 1 - unadjusted quoted prices in active markets for identical assets or liabilities.
•	Level 2 - inputs other than quoted prices included in Level 1 that are observable for the assets or<br>liabilities, either directly or indirectly.
---	---
•	Level 3 - inputs for the assets or liabilities that are not based on observable market data.<br>
---	---

If the inputs used to measure the fair value of an asset or a liability might be categorized in different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

3. Summary of Material Accounting Policy Information

Except for the items described below, the accounting policies applied by the Group in these interim condensed consolidated financial statements are the same as those applied to the consolidated financial statements as of and for the year ended December 31, 2024.

Changes	in accounting policies
(a)	Amendments to KIFRS 1021: Lack of Exchangeability
---	---

The amendments to KIFRS 1021 The Effects of Changes in Foreign Exchange Rates specify how an entity should assess whether a currency is exchangeable and how it should determine a spot exchange rate when exchangeability is lacking. The amendments also require the disclosure of information that enables users of its financial statements to understand how the currency that is not exchangeable into the other currency affects, or is expected to affect, the Group’s financial performance, financial position, and cash flows.

The amendments will be effective for annual reporting periods beginning on or after January 1, 2025. When applying the amendment, the Group is not required to restate comparative information.

The amendments are not expected to have a material impact on the Group’s interim condensed consolidated financial statements.

26. Contract under Input Method (cont’d)

(e)	Uncertainty of estimates
1)	Total contract revenues
---	---

Total contract revenues are measured based on contractual amount initially agreed. However, the contract revenues can increase due to additional contract work, claims and incentive payments, or decrease due to penalty when the completion of contract is delayed due to the Group’s fault. Therefore, this measurement of contract revenues is affected by the uncertainty of the occurrence of future events.

2)	Total contract costs

Contract revenues are recognized based on the percentage of completion, which is measured on the basis of the gross cost amount incurred to date. Total contract costs are estimated based on estimates of future material costs, labor costs, outsourcing costs. There is uncertainty in estimates on future contract costs due to various internal and external factors such as fluctuation of market, the risk of business partner and the experience of project performance and others. The significant assumptions including uncertainty of the estimate of total contract costs are as follows:

	Method of significant assumption
Material cost	Assumption based on recent purchasing price and quoted market price
Labor cost	Assumption based on standard monthly and daily labor cost
Outsourcing cost	Assumption based on the past experience rate of similar project and market price

Management reviews estimated contract costs at each reporting period end and adjusts them, if necessary.

31. Income Taxes

The effective tax rates of the Group for each of the six-month periods ended June 30, 2025 and 2024 are 41.96% and 20.52%, respectively.

(a)	Application of the Consolidated Tax Payment System

In 2025, the Group has applied the consolidated tax payment system, under which a controlling company and its domestic subsidiaries, if economically integrated, are treated as a single tax entity for corporate income tax purposes. Under this system, the controlling company, as the consolidated parent entity, is responsible for filing and paying the corporate income tax on behalf of the entire consolidated group. After payment, the parent company collects the corresponding tax amounts from each domestic subsidiary.

Domestic and foreign subsidiaries that are not included in the consolidated tax payment system calculate and pay corporate income tax based on each legal entity as a separate tax unit.

Deferred tax assets and deferred tax liabilities of entities included in the consolidated tax payment system are offset when the Group has a legally enforceable right to offset current tax assets against current tax liabilities, and the deferred tax assets and liabilities relate to income taxes levied by the same tax authority and there is an intention to settle them on a net basis.

(b)	Global minimum tax

In 2023, Pillar Two legislation has been enacted in the Republic of Korea, where the controlling company is domiciled, which is effective for the fiscal years starting on or after January 1, 2024. Accordingly, the Group calculated the Pillar Two income tax expense for the six-month period ended June 30, 2025 as it is subject to global minimum tax under the OECD’s Pillar Two Model Rules. The Group reviewed subsidiaries qualifying as taxpayers, including the controlling company and, as a result, did not recognize any income tax expense for the six-month period ended June 30, 2025 as the impact of the global minimum tax on the consolidated financial statements as of June 30, 2025 would not be significant. Furthermore, the Group applies temporary exception to the recognition and disclosure of deferred taxes arising from the jurisdictional implementation of the Pillar Two Model Rules as prescribed in KIFRS 1012 Income Taxes. Accordingly, it did not recognize deferred tax assets and liabilities related to the global minimum tax and does not disclose information related to deferred income tax.

34. Commitments and Contingencies

(a)	Contingent liabilities

Contingent liabilities can change due to unforeseen circumstances; therefore, management continuously reviews whether the likelihood of an outflow of resources embodying economic benefits has increased. Except in extremely rare circumstances where it cannot be reliably estimated, if the likelihood of an outflow of future economic benefits has increased, even if it had been treated as a contingent liability in the past, such changes in likelihood are recognized as a provision in the consolidated financial statements for the period in which the change occurred.

Management of the Group makes estimates and assumptions that affect disclosures of commitments and contingencies. All estimates and assumptions are based on the evaluation of current circumstances and appraisals with the support of internal and/or external specialists.

Management of the Group regularly analyzes the most current information on contingent events and provides information regarding provisions related to contingent losses, including potential estimated legal costs. Such assessments are based on consultations with internal and external legal counsel. In making the decision on the recognition of a provision, management considers the likelihood of an outflow of resources embodying economic benefits to settle the obligation and the possibility of making a reliable estimate of the amount.

(b)	Details of guarantees
1)	Contingent liabilities from outstanding guarantees provided by the Group as of June 30, 2025 are as<br>follows:

1. Reporting Entity

The shares of the Company have been listed on the Korea Exchange since June 10, 1988. The Company operates an investment business that controls and manages through ownership of shares of subsidiaries etc.

As of June 30, 2025, the shares of the Company are listed on the Korea Exchange, while its ADRs are listed on the New York Stock Exchanges.

2. Basis ofpreparation

Statement of compliance

The interim condensed separate financial statements have been prepared in accordance with KIFRS 1034 Interim Financial Reporting, as prescribed in the Act on External Audit of Stock Companies of the Republic of Korea. The accompanying interim condensed separate financial statements have been translated into English from the Korean language financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s review report thereon, the Korean version, which is used for regulatory reporting purposes, shall prevail.

The interim condensed separate financial statements do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Company’s annual financial statements as of December 31, 2024. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Company incurred after December 31, 2024. These interim condensed separate interim financial statements do not include all of the disclosures required for full annual financial statements.

These condensed interim financial statements are separate interim financial statements prepared in accordance with KIFRS 1027 Separate Financial Statements presented by a parent, an investor with joint control of, or significant influence over an investee, in which the investments are accounted for at cost.

POSCO HOLDINGS INC.

Notes to the interim condensed separate financial statements, continued

2. Basis of preparation (cont’d)

Use of estimates and judgments

(a)	Judgments, assumptions and estimation uncertainties

The preparation of the interim condensed separate financial statements in conformity with KIFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period prospectively.

The significant judgments made by management in applying the Company’s accounting policies and the key sources of estimation uncertainty were the same as those described in the annual financial statements as of and for the year ended December 31, 2024 except for the matters mentioned below.

(b)	Measurement of fair value

The Company’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Company has an established control framework with respect to the measurement of fair values. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values, and reports directly to the financial officer.

Significant valuation issues are reported to the Company’s Audit Committee.

When measuring the fair value of an asset or a liability, the Company uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows.

POSCO HOLDINGS INC.

Notes to the interim condensed separate financial statements, continued

June 30, 2025 and 2024 (Unaudited)

2. Basis of preparation (cont’d)

•	Level 1 – unadjusted quoted prices in active markets for identical assets<br>or liabilities.
•	Level 2 – inputs other than quoted prices included in Level 1 that<br>are observable for the assets or liabilities, either directly or indirectly.
•	Level 3 – inputs for the assets or liabilities that are not based on<br>observable market data.

If the inputs used to measure the fair value of an asset or a liability might be categorized in different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

3. Summary of MaterialAccounting Policy Information

Except for the items described in KIFRS 1034 Interim Financial Reporting and below, the accounting policies applied by the Company in these interim condensed separate financial statements are the same as those applied to the separate financial statements as of and for the year ended December 31, 2024.

Amendments to KIFRS 1021: Lack of Exchangeability

The amendments to KIFRS 1021 The Effects of Changes in Foreign Exchange Rates specify how an entity should assess whether a currency is exchangeable and how it should determine a spot exchange rate when exchangeability is lacking. The amendments also require the disclosure of information that enables users of its financial statements to understand how the currency that is not exchangeable into the other currency affects, or is expected to affect, the Company’s financial performance, financial position, and cash flows.

The amendments will be effective for annual reporting periods beginning on or after January 1, 2025. When applying the amendment, the Company is not required to restate comparative information The amendments are not expected to have a material impact on the Company’s interim condensed separate financial statements.

28. Income Taxes

The effective tax rates of the Company for each of the six-month periods ended June 30, 2025 and 2024 are 1.9% and 1.1%, respectively.

(a)	Income taxes

The Company vertically spun off its steel business at the spin-off date on March 1, 2022. The Company’s vertical spin-off meets the requirements for qualified spin-off under the Corporate Tax Act. Accordingly, transfer gains of ~~W~~8,452,339 million under the Corporate Tax Act were incurred for the net asset transferred to the newly established company (POSCO). For the transfer gain, the Company simultaneously set provision for accelerated depreciation and recognized deferred tax liabilities.

Deductible temporary differences related to the investment in newly established company (POSCO), which arise from transfer gains under the Corporate Tax Act, were not recognized as deferred tax assets, since it is not probable they will reverse through disposal or liquidation.

28. Income Taxes (cont’d)

(b)	Application of the Consolidated Tax Payment System

From the six-month period ended June 30, 2025, the Company has applied the consolidated tax payment system, under which a controlling company and its domestic subsidiaries, when economically integrated, are treated as a single tax entity for corporate income tax purposes. Under this system, the controlling company, as the consolidated parent entity, is responsible for filing and paying the corporate income tax on behalf of the entire consolidated group. After payment, the parent company collects the corresponding tax amounts from each domestic subsidiary.

The current tax assets and current tax liabilities recognized in relation to the consolidated tax payment system for the six-month period ended June 30, 2025 and the year ended December 31, 2024 are as follows:

(in millions of Won)	June 30, 2025
Current income tax assets(*1)	~~W~~	—	27,940
Current income tax liabilities(*2)		222,431	—
(*1)	Presenting the expected corporate income tax refund during the year ended December 31, 2024.<br>
---	---
(*2)	Presenting the amount calculated and recognized by applying the consolidated tax payment system during the six-month period ended June 30, 2025.
---	---
(c)	Global minimum top-up tax
---	---

In 2023, Pillar Two legislation has been enacted in the Republic of Korea, where the Company is domiciled, which is effective for the fiscal years starting on or after January 1, 2024. Accordingly, the Company calculated the Pillar Two income tax expense for the six-month period ended June 30, 2025 as it is subject to global minimum top-up tax under the application of the OECD’s Pillar Two Model Rules via domestic legislation. The Company reviewed subsidiaries qualifying as taxpayer, including the Company, and, as a result, did not recognize any income tax expense for the six-month period ended June 30, 2025 as the impact of the global minimum top-up tax on the separate financial statements as of June 30, 2025 would not be significant. Furthermore, the Company applies temporary exception to the recognition and disclosure of deferred taxes arising from the jurisdictional implementation of the Pillar Two Model Rules as prescribed in KIFRS 1012 Income Taxes. Accordingly, it did not recognize deferred tax assets and liabilities related to the global minimum top-up tax and does not disclose information related to deferred income tax.
