1. Business Snapshot and Recent Developments

Korea Mine Rehabilitation and Mineral Resources Corporation (“KOMIR”) is a government-related issuer in the mineral resources and mine rehabilitation sector that is 100% owned by the Korean government. It should be viewed not as an ordinary commercial mining company or a pure environmental remediation agency, but as a policy implementation vehicle that combines Korea’s critical-mineral security, support for the domestic mining industry, mine rehabilitation, strategic stockpiling, and the resolution of legacy overseas resource investments. For bond investors, the primary question is how far the issuer’s close linkage with the Korean government offsets its negative equity, operating cash flow deficit, large refinancing needs, and legacy losses from overseas resource investments.

KOMIR was established in September 2021 through the merger of the former Korea Resources Corporation (“KORES”) and Mine Reclamation Corporation (“MIRECO”). KORES was a state-owned resource-development agency established in 1967 and had been responsible for securing mineral resources in Korea and overseas. MIRECO, by contrast, was a mine rehabilitation agency established in 2006, with a mandate close to safety, environmental remediation, and regional economic revitalisation in closed and abandoned mining areas. The merger of these two entities made KOMIR an issuer that simultaneously performs two policy functions that are difficult to explain by commercial profitability alone: securing resources and rehabilitating mining damage.

This corporate profile is critical in assessing KOMIR’s credit quality. Looking only at KOMIR’s income statement and balance sheet, its standalone financial profile is weak. At end-2025, total assets were KRW4.90 trillion, total liabilities were KRW8.07 trillion, and total equity was negative KRW3.16 trillion. In 2025, the company also recorded an operating loss of KRW85.9 billion, a net loss of KRW344.4 billion, and negative operating cash flow of KRW566.3 billion. For an ordinary mining company or a commercial non-bank financial institution, it would be difficult to explain a high investment-grade rating based on these financials alone.

However, KOMIR is not an ordinary private-sector company. According to the GMTN Offering Circular dated 25 March 2026, the company is a statutory juridical corporation established under the KOMIR Act. The KOMIR Act establishes the company for the purposes of preventing mining damage, improving the performance of domestic and overseas mineral-resource development projects, and promoting and supporting Korea’s mineral-resource business. The Act defines its businesses as including mine rehabilitation, compensation for mining damage, exploration and development of domestic and overseas mineral resources, investments in resource-related companies, financing for resource development, smelting and stockpiling, stockpiling, sale and lending of minerals, mine safety, and the management of mine exploration data. The Act also provides room for government involvement through government equity contributions, supervision by the competent minister, the possibility of government guarantees, subsidies, and the treatment of losses.

There have been two important recent developments. First, on 25 March 2026, the Offering Circular for the US$5 billion Global Medium Term Note Programme was updated, providing the 2025 audited consolidated financial statements and the latest programme terms. Second, in April 2026, KOMIR issued US$500 million of 4.875% notes due 2031. SGX disclosures show that KOMIR continues to have access to the international US dollar bond market. This indicates that, despite weak standalone financials, the credit uplift associated with its government-related issuer status and its investor base remain functional.

However, the ability to issue US dollar bonds and the existence of a Korean government guarantee on the bonds are two different matters. The KOMIR Act provides that the government may guarantee the principal and interest of KOMIR bonds and also indicates that the government may provide subsidies for its business activities. However, the 2026 GMTN Offering Circular explicitly states that the Notes are not guaranteed by the Korean government. KOMIR therefore needs to be analysed by distinguishing among the likelihood of government support, KOMIR’s own repayment capacity, and the legal protection attached to individual bonds.

The opening investment profile is therefore clear. KOMIR is an issuer in which 100% government ownership, the 2021 KORES/MIRECO merger, policy mandates under the KOMIR Act, negative equity at end-2025, US dollar bond issuance in 2026, and A1/A+/A+ ratings coexist. Credit analysis should place substantial weight on policy importance and government support, while separately assessing the weakness of the standalone financial profile and the absence of a government guarantee.

2. Policy Mandate and Government Linkage

KOMIR’s credit quality cannot be explained without its linkage to the government. However, it would be risky to collapse government support into a single label. KOMIR benefits from multiple support channels: ownership and supervision, policy mandates, capital injections, subsidies, the possibility of government guarantees, a support letter, rating-agency incorporation of support, and the domestic market’s acceptance of the issuer as a government-related borrower. At the same time, the 2026 GMTN Notes are not government-guaranteed, and the support letter is not a legally binding payment guarantee. Distinguishing between the strength and the limits of this support is central to the KOMIR credit report.

The strongest basis for support is the company’s establishing legislation and ownership structure. KOMIR is a public corporation that is 100% funded by the government. Under the KOMIR Act, its authorised capital is KRW3 trillion and only the government may subscribe for its capital. The Offering Circular states that the Minister of MOTIR has the authority to direct and supervise KOMIR’s activities relating to its business. The explanation of the 2016 government plan uses the ministry names MOFE and MOTIR. This report uses the terminology in the bond documents as it appears; the correspondence with current government-organisation names remains an unverified item.

The next important point is that the KOMIR Act specifies the forms of support. The Act provides that KOMIR may issue bonds within an amount not exceeding 200% of the aggregate of its capital and reserves, that the government may guarantee the repayment of principal and interest on KOMIR bonds, and that the government may provide subsidies for KOMIR’s business activities. It also provides that annual losses are to be applied first against the business expansion reserve, then against the earned-surplus reserve, and that, if the shortfall remains, the government may assume the residual loss. Given that consolidated total equity was negative at end-2025, how this bond issuance limit is applied in practice to capital and reserves, government approvals, outstanding bonds, and individual issuances is an important unverified point. This report therefore treats this clause as evidence of government support and an institutional issuance framework, not as a basis for assuming unlimited bond issuance even under negative equity.

However, this legal framework does not mean that all ordinary bonds automatically carry a government guarantee. The Offering Circular explicitly states that the Notes are not guaranteed by the government. Accordingly, the direct obligor for investors is KOMIR or a Guaranteed Issuer that has acceded to the programme. Even for bonds issued by a Guaranteed Issuer, the guarantor is KOMIR, not the Korean government. The likelihood of government support is high, but the legal claim is not a direct obligation of the government.

The 2018 government support letter should be read in the same way. The OC explains that, on 21 March 2018, the Director General for Energy and Resources Policy at MOTIR issued a letter indicating a support stance for KOMIR’s predecessor. This can serve as evidence for rating agencies and the market in assessing the government’s support stance. However, the OC’s risk factors indicate that the support letter is not a guarantee and is not a legally binding government obligation. The support letter is evidence of credit support, but it is not a contractual payment guarantee.

The reason government support is strong is that the company is embedded in Korea’s resource security policy. Korea has an industrial base linked to energy, semiconductors, batteries, automobiles, shipbuilding, defence, and renewable energy, while the domestic availability and economic viability of major mineral resources are limited. Stable access to critical minerals, overseas resource information, support for private-sector companies, stockpiling, recycling, mine safety, and abandoned-mine rehabilitation are relevant to both industrial policy and national security. KOMIR is positioned as the sole or central public resource agency responsible for these policy challenges.

However, government support is both a credit support factor and a source of policy burden. The former KORES pursued overseas mining investments under the government’s overseas resource-development policy and subsequently faced commodity-price declines, underperformance of investment projects, impairments, and debt burdens. In June 2016, MOFE and MOTIR announced a government plan to rationalise overseas natural-resource development activities by government-controlled enterprises. For government-controlled enterprises including KOMIR’s predecessor, the plan set out a direction of gradually withdrawing from overseas exploration, development, and production businesses while strengthening support services for private-sector companies. This history shows that government policy can be both a source of support and a source of burden.

Government support can be broken down into 100% government ownership and supervision, policy mandates under the KOMIR Act, capital injections, subsidies, the possibility of government guarantees, the possibility of residual loss assumption, the 2018 support letter, and rating-agency incorporation of support. These factors strongly support the likelihood of support and market access, but none of them automatically converts ordinary KOMIR bonds into direct obligations of the Korean government. For bondholders, it is important to assess both the breadth of available support tools and the limits of the legal path through which those tools reach individual bonds.

S&P’s initial rating report illustrates this structure well. In 2021, S&P viewed the likelihood of extraordinary support from the Korean government to KOMIR in the event of need as extremely high. It cited KOMIR’s role as the sole policy-implementation agency in Korea’s mineral-resource policy, full government ownership, strong financial support, and tight government oversight and control. At the same time, the same report pointed to the low quality of overseas mining assets, continuing losses in mining operations, high leverage due to debt, and weak cash-generating capacity. In other words, KOMIR’s rating is not high because its standalone financial profile is strong; it is high on a support-inclusive basis because standalone financials are weak but the likelihood of government support is extremely high.

This report therefore treats KOMIR as a mineral-resource policy agency close to the Korean government. However, the bonds investors buy are not sovereign obligations but KOMIR credit. The support-inclusive credit profile is strong, but for bonds without a government guarantee, KOMIR’s refinancing capacity, the timeliness of government support, sovereign credit quality, and the terms of individual bonds all need to be assessed together.

3. Industry Position and Franchise Strength

KOMIR’s business platform should be assessed not by market share or mine production volume, but by how difficult it would be to replace within Korea’s mineral-resource policy. The company is not a global mining major. It is a policy platform that connects resource information, exploration support, stockpiling, financial and technical support, mine safety, mine rehabilitation, and the resolution of overseas investments. Korea’s semiconductor, battery, automobile, defence, and energy-transition industries depend on critical-mineral supply chains, and KOMIR is the government’s institutional response to this supply constraint.

Domestically, support for domestic mines, mine rehabilitation, mine safety, and the revitalisation of mining areas are important functions. Mine rehabilitation is a public service rather than a high-margin business. It addresses ground subsidence, drainage, heavy metals, and regional revitalisation issues that are difficult to handle on a purely private-sector profitability basis. This function is credit-positive not because of its profitability, but because it increases the government’s need to maintain KOMIR.

In resource-development support, KOMIR provides information, technology, financing, and risk assessment when private Korean companies seek access to overseas mineral-resource projects. Supplementary media reporting in 2026 has indicated a direction of strengthening public support, but this report treats such reports only as observational evidence of policy direction. The credit assessment is based mainly on items confirmed in the OC and the KOMIR Act.

By contrast, overseas investments inherited from the former KORES are a burden. Commodity-price declines, operational underperformance, partner risk, and local policy risk damaged its financial position, and the 2016 government plan called for the rationalisation of overseas direct investments and a shift toward supporting private-sector companies. Losses, guarantees, and associate-company risks from existing investments do not disappear quickly, and this complicates the assessment of KOMIR’s franchise.

To read KOMIR’s business platform as a credit strength, three conditions need to be confirmed. First, the government must maintain the company’s policy mandates and continue to provide the necessary capital, budgetary, and institutional support. Second, losses from legacy overseas investments must not generate new large-scale funding needs. Third, new policy demands related to resource security should be designed around private-sector support, information, stockpiling, recycling, and risk sharing, rather than becoming concentrated again in high-risk overseas direct investments.

The conclusion on franchise strength is that KOMIR’s policy irreplaceability is strong, while its commercial earnings base is not. This is a strength in assessing government support, but a constraint in assessing standalone financials. KOMIR’s credit profile is likely to be misread if one focuses only on one side, either “safe because it is government-related” or “risky because it has negative equity,” without separating these two dimensions.

4. Segment Assessment

KOMIR’s businesses are more practically assessed by policy function, risk, and funding need than by commercial segment profit. Mine rehabilitation and support for mining areas are highly public functions inherited from MIRECO and are one reason the government needs to maintain the company. Domestic mining and resource-development support assists domestic resource-related companies through exploration, technology, data, financing support, mine safety, and human-resource and information support. Strategic stockpiling and mineral management are designed to secure the supply of critical minerals and therefore differ in nature from ordinary inventory businesses.

The largest source of volatility is overseas resource investments and related companies. Investments related to Boleo, Ambatovy, and Cobre Panama are exposed to commodity prices, operations, local governments, co-investors, legal disputes, liquidity, and impairments. KOMIR is responsible for policy-driven resource security, but as a minority investor or non-operator it may not be able to fully control projects. Losses and valuation losses from legacy overseas investments are a major factor behind negative equity.

Boleo is a copper-related investment in Mexico. The 2025 financial information shows large losses at Minera Metalurgica del Boleo and Korean Boleo Corporation, with the latter having liabilities far in excess of assets. Cobre Panama is an 8.98% equity interest, with cumulative investment of KRW865.6 billion at end-2025, and has been suspended since December 2023. Ambatovy is a 38.17% equity interest, with cumulative investment of KRW2,613.0 billion at end-2025, and an additional capital contribution of KRW88.1 billion is expected in 2026. For all of these projects, strategic significance and financial burden should be assessed separately.

The fifth function is funding. KOMIR is a policy agency, but it is also an issuer that raises funds through market debt. The GMTN programme under the 2026 OC is US$5 billion. KOMIR itself or Guaranteed Issuers may issue under the programme, and bonds issued by Guaranteed Issuers are guaranteed by KOMIR. Under negative equity and operating cash flow deficits, maintaining the ratings and the expectation of government support is essential for refinancing maturities.

From this segment assessment, KOMIR is an issuer whose policy functions support government support, while overseas investments constrain standalone financials. Credit analysis needs to continue monitoring how far KOMIR re-expands overseas direct-investment risk, or whether it remains focused on support for private-sector companies, stockpiling, recycling, and information functions.

5. Financial Profile and Analysis

KOMIR’s financial profile most clearly demonstrates the gap between support-inclusive credit quality and standalone credit quality. At end-2025, total equity was negative KRW3.16 trillion. This was an improvement from negative KRW3.76 trillion at end-2024, but equity remained deeply negative. Total liabilities were KRW8.07 trillion, and borrowings and bonds were KRW7.87 trillion on a book-value basis. KOMIR is a refinancing-driven issuer that depends on market funding and the expectation of government support.

On the earnings side, 2025 did not mark a clear return to profitability. Revenue was KRW621.9 billion, down from KRW757.9 billion in 2024. Operating loss was KRW85.9 billion, slightly wider than the KRW68.1 billion loss in 2024. Net loss was KRW344.4 billion, much narrower than the KRW1,181.7 billion loss in 2024, but still a loss. Given that the large 2024 loss was likely heavily affected by overseas investments and valuation losses, the smaller 2025 loss is an improvement. However, it should not be read as evidence that underlying earnings have sustainably turned profitable.

Cash flow is more severe. Operating cash flow was negative KRW566.3 billion in 2025, worsening from negative KRW241.5 billion in 2024. Investing cash flow was also negative KRW350.9 billion, while positive financing cash flow of KRW802.6 billion filled the funding gap. This shows that KOMIR is not repaying debt from operating cash flow; it is maintaining liquidity through borrowings, bonds, and other financing.

A comparison of 2023 to 2025 shows that negative equity first deteriorated and then partially improved. Total equity was negative KRW2.54 trillion at end-2023, negative KRW3.76 trillion at end-2024, and negative KRW3.16 trillion at end-2025. It deteriorated sharply in 2024 and improved in 2025, but the absolute level of equity remains deeply negative. The audited financial statements in the 2024 OC included material uncertainty related to going concern at end-2023, when current liabilities exceeded current assets by KRW1.12 trillion and total liabilities exceeded total assets by KRW2.54 trillion. Even after partial improvement in 2025, the fundamental weakness of standalone credit quality remains.

Key financial indicators are as follows.

Note: FY2023 figures were extracted from the audited consolidated financial statements included in the 2024 OC. FY2024 and FY2025 figures were extracted from the audited consolidated financial statements included in the 2026 OC. Unit: KRW billion. The working capital shortfall is the figure confirmed in the 2023 going-concern note; the same-format figures for 2024 and 2025 were not confirmed in this report.

The most important point from this table is that KOMIR appears very weak if assessed using the leverage and profitability framework of an ordinary operating company. An issuer whose total liabilities exceed total assets, whose operating cash flow is negative, and whose near-term maturities are large would ordinarily be analysed primarily through refinancing risk. KOMIR also has refinancing risk as a central issue, but that risk is mitigated by the expectation of government support and by market access.

The improvements in 2025 were in total liabilities and total equity. Total liabilities declined from KRW8.58 trillion at end-2024 to KRW8.07 trillion at end-2025, and the negative equity position narrowed from KRW3.76 trillion to KRW3.16 trillion. This indicates a narrowing of losses and some improvement in capital, valuation items, or liability management. However, because operating losses and negative operating cash flow remain, the improvement is still more a partial easing of stress than a normalisation of the financial structure.

The negative developments in 2025 were operating cash flow and revenue. Lower revenue and a wider operating cash flow deficit indicate that KOMIR has limited capacity to reduce debt on its own. Without resource-asset disposals, government capital injections, subsidies, refinancing, or bond issuance, it would be difficult to absorb near-term maturities. KOMIR’s financial analysis therefore needs to examine not only operating profit and net loss, but also borrowings and bond maturities, cash and financial assets, government support, and access to the bond market.

Asset quality is difficult to assess using indicators such as the NPL ratio used for ordinary financial institutions. KOMIR’s main risks lie not only in overdue domestic loans, but also in overseas mining investments, associates, joint ventures, guarantees, loss allowances, impairments, arbitration, and litigation. The 2026 OC includes information on top-10 concentration and non-performing loans in domestic resource-development lending, but the principal driver of negative equity should be viewed as accumulated losses from legacy overseas resource investments and the funding burden, rather than domestic lending.

The overall financial assessment is that KOMIR’s standalone credit quality is fragile. Negative equity, negative operating cash flow, and refinancing dependence are clear constraints and are not a financial profile that would support a high rating on a standalone basis. As a government-supported issuer, however, its policy importance, 100% government ownership, support mechanisms under the KOMIR Act, international ratings, and bond-market access offset the weakness of standalone financials. Investors should clearly separate these two layers.

6. Structural Considerations for Bondholders

For bondholders, the most important structural issue for KOMIR is the gap between the expectation of government support and the legal claim. KOMIR is a government-related issuer, and rating agencies incorporate substantial government support. However, KOMIR’s GMTN Notes are not guaranteed by the Korean government. The direct obligor for investors is KOMIR itself or a Guaranteed Issuer that has acceded to the programme, and for bonds issued by a Guaranteed Issuer, the guarantor is KOMIR.

The 2026 GMTN programme is structured so that KOMIR itself or a subsidiary of the company may act as issuer. If a subsidiary issues as a Guaranteed Issuer, KOMIR acts as guarantor. This provides flexibility for funding within the KOMIR group. At the same time, investors need to review the issuer, guarantor, governing law, currency, tax, paying agent, cross default, negative pledge, and waivers on an issue-by-issue basis.

For bonds issued by KOMIR itself, creditors have a direct claim on KOMIR. KOMIR’s repayment capacity depends not only on operating cash flow, but also on the expectation of government support, access to domestic and international markets, existing assets, short-term refinancing, and government policy decisions. For bonds issued by a Guaranteed Issuer, the issuer is a subsidiary, but the KOMIR guarantee brings the ultimate credit risk close to that of KOMIR itself. This guarantee, however, is not a Korean government guarantee.

The possibility of a government guarantee under the KOMIR Act is important. The Act provides that the government may guarantee repayment of principal and interest on KOMIR bonds, leaving institutional room for explicitly government-guaranteed funding under deep stress. However, “may guarantee” and “this bond is guaranteed” are different propositions. The 2026 OC explicitly states that the Notes are not guaranteed by the Korean government. It would therefore be inappropriate to treat ordinary KOMIR foreign-currency bonds as having the same legal risk as Korean government bonds.

Structural issues can be divided into the issuer, guarantor, presence or absence of a government guarantee, governing law, listing, negative pledge, cross default, waiver of immunity, tax, and currency restrictions. For bonds issued by KOMIR itself, creditors rely directly on KOMIR. For Guaranteed Issuer bonds, a subsidiary issuance is supported by a KOMIR guarantee. In both cases, the substantive reliance is on KOMIR credit, the likelihood of government support, and bond-market access, not on a direct obligation of the Korean government.

In addition, the operation of the bond issuance limit remains an item requiring confirmation. The KOMIR Act sets an issuance limit linked to the aggregate of capital and reserves, while consolidated total equity was negative at end-2025. Because the OC shows outstanding bonds and new 2026 bonds, what matters for individual issuances includes government approvals, the calculation of statutory capital and reserves, whether consolidated or separate financial statements are used, and how the issuance capacity under the existing programme is treated. This report does not make a definitive statement on the specific operation of the statutory limit and treats it as a legal and issuance-terms item to be checked before investing in individual bonds.

From a bondholder perspective, KOMIR’s issuer credit is strongly supported by its government-related status, but terms review is essential for individual bond investments. In particular, ranking, collateral, cross default, negative pledge, tax gross-up, change of control, currency restrictions, acceleration provisions, and the scope of the KOMIR guarantee affect actual recovery prospects. This is an issuer credit report and does not provide a complete legal analysis of individual bond terms, but the absence of a government guarantee should be retained clearly in the analysis.

The subsidiary and associate structure is also important for an issuer with overseas resource investments. KOMIR is involved in overseas investments through local entities and joint ventures related to Boleo, Ambatovy, and Cobre Panama. Where the assets, liabilities, and guarantees sit, and how far KOMIR itself has support obligations, matter when losses materialise. The 2026 OC’s consolidated financial statements provide an overall picture, but before investing in individual bonds, it is necessary to check Boleo guarantees, subsidiary debt, and additional support obligations to associates.

The structural conclusion is that KOMIR bonds are quasi-sovereign bonds with a strong expectation of government support, not bonds directly guaranteed by the Korean government. This difference may appear only modestly in spreads and ratings in normal times, but it becomes important under stress. Even if the government’s willingness and ability to support KOMIR are high, the form, timing, and path through which support reaches individual bonds depend on contracts and policy decisions.

7. Capital Structure, Liquidity and Funding

KOMIR’s liquidity needs to be assessed not only by cash balances, but also by its refinancing capacity as a government-related issuer. At end-2025, cash and cash equivalents were KRW344.2 billion and current financial assets were KRW490.4 billion, for a total of KRW834.6 billion. By contrast, scheduled principal and interest repayments on borrowings and bonds within one year at end-2025 were KRW2.46 trillion. Cash and current financial assets alone are not sufficient to fully cover near-term maturities.

The maturity schedule for borrowings and bonds shows that KOMIR is a refinancing-driven issuer. At end-2025, scheduled principal and interest repayments on borrowings and bonds totalled KRW7.87 trillion, of which KRW2.46 trillion was due within one year, KRW4.73 trillion within more than one year and up to five years, and KRW0.68 trillion after more than five years. Given the high share of near-term maturities and negative operating cash flow, KOMIR maintains liquidity on the assumption that market funding and the expectation of government support remain available.

Note: Unit: KRW billion. Based on the repayment schedule for borrowings and bonds in the 2026 OC. There is a note stating that long-term borrowings do not include certain borrowings from the Special Account for Energy and Resources.

Funding sources are multilayered. KOMIR uses domestic short-term borrowings and CP, domestic bonds, foreign-currency bonds, and the GMTN programme. Short-term borrowings at end-2025 included CP through multiple securities companies, with many maturities falling in 2026. The US$500 million 4.875% notes due 2031 issued in April 2026 are evidence that part of the near-term maturity profile has been extended and that access to the foreign-currency market remains open.

However, foreign-currency bond issuance also brings new risks. KOMIR is an issuer with Korean won-denominated revenues and expenses as well as overseas resource investments. US dollar bonds are affected by FX risk, hedging costs, US dollar rates, and international investors’ preference for Korean quasi-sovereigns. The OC provides the won-dollar exchange-rate trend and shows a period of won depreciation from end-2024 to March 2026. KOMIR’s foreign-currency debt, hedge ratio, and matching with foreign-currency assets and revenues are important items to confirm before investing in individual bonds.

The first liquidity support factor is the rating profile. Under the 2026 OC, KOMIR is rated Moody’s A1, S&P A+, and Fitch A+, all with Stable outlooks. The maintenance of these ratings despite weak standalone financials supports market access on a support-inclusive basis. Domestic and international investors treat KOMIR not as an ordinary mining company but as a Korean government-related issuer. Based on the April 2026 US dollar bond issuance and A-category ratings, market access in normal conditions appears to remain intact.

The second support factor is the institutional room for government support. The KOMIR Act indicates the possibility of government guarantees, subsidies, and residual loss assumption. Under deep stress, the government would have room to consider capital, subsidies, guaranteed funding, or support through policy financial institutions. This is a major credit offset for an issuer with limited standalone cash.

The third support factor is KOMIR’s policy mandate. Resource security, mine rehabilitation, and critical-mineral stockpiling are not functions that the government can easily abandon merely because short-term profitability is weak. The continuity of these policy mandates is a reason the government is unlikely to leave the company’s liquidity entirely to the market.

At the same time, liquidity constraints are clear. Cash and current financial assets combined do not fully cover maturities within one year, and operating cash flow is negative. Positive financing cash flow in 2025 indicates dependence on funding. If market access were temporarily closed, the government support stance were questioned, the Korean sovereign came under stress, or additional losses from overseas investments occurred, standalone liquidity could tighten rapidly.

The liquidity assessment is that KOMIR is not an issuer with a large cash cushion. It maintains liquidity through refinancing capacity supported by the expectation of government support and high ratings. The April 2026 issuance confirms continued market access, but one issuance should not be viewed as eliminating the refinancing risk for the full near-term maturity profile. Before investing in individual bonds, it is necessary to confirm committed lines, debt by currency, hedging, bank loan terms, domestic CP rollover, and redemption plans for US dollar bonds.

8. Rating Agency View

KOMIR’s ratings are essential to assessing its credit quality, but the rating level should not be confused with standalone financial strength. According to the 2026 OC, KOMIR is rated A1 by Moody’s, A+ by S&P, and A+ by Fitch, all with Stable outlooks. These levels would be difficult to explain for an ordinary mining company with negative equity and negative operating cash flow, and should be understood as support-inclusive quasi-sovereign credit ratings.

S&P’s 2021 initial rating made this point clear. S&P assessed the likelihood of extraordinary support from the Korean government to KOMIR in the event of need as extremely high. The basis was KOMIR’s role as the sole policy institution in Korea’s mineral-resource policy, full government ownership, and strong government financial support, supervision, and control. At the same time, S&P pointed to the low quality of overseas mining assets, losses in mining operations, large debt, and weak cash-generating capacity. This combination still broadly applies to KOMIR today.

The ratings shown in the OC are as follows.

The first point in reading the ratings is KOMIR’s distance from the Korean sovereign. KOMIR is not a direct government obligation, but because it is highly rated on a support-inclusive basis, it is likely to be strongly linked to Korea’s sovereign rating, fiscal capacity, government willingness to support, and policy treatment of quasi-sovereigns. If Korea’s sovereign rating deteriorated, KOMIR’s rating and spreads could be affected through support capacity or rating-ceiling considerations even if KOMIR’s standalone financials did not change.

The second point is the assessment of government support. If any of government ownership, policy mandate, capital injections, subsidies, the possibility of government guarantees, the support letter, or supervision and control were weakened, rating agencies could reassess the likelihood of support. For example, a change in government ownership, a narrowing of KOMIR’s policy mandate, a case in which the government delays loss absorption, insufficient capital injections, or a mismatch between the support letter and actual support actions could become negative rating factors.

The third point is standalone credit quality. For a support-inclusive issuer, a single-year loss or negative equity does not necessarily lead directly to a downgrade. However, if overseas investment losses expand, operating cash flow deficits persist, short-term debt increases, and the required amount of government support becomes larger, the support-inclusive credit profile could also be affected. In particular, if new large-scale losses or additional support obligations arise from legacy overseas investments, rating agencies would likely reassess both the timeliness of government support and the sustainability of standalone financials.

The fourth point is bond structure. High ratings indicate low default probability, but they do not fully explain the legal protection of individual bonds. The presence or absence of a government guarantee, the scope of the KOMIR guarantee, whether the bond is issued by a subsidiary or by KOMIR itself, contractual terms, currency, and governing law all need to be checked separately.

The conclusion on ratings is that KOMIR is positioned in the upper A category as a Korean government-supported quasi-sovereign. The ratings are a major credit support factor, but they do not erase the weakness of standalone financials. Investors should use the ratings as a starting point, while also checking the form of government support, sovereign linkage, overseas investment risk, and short-term liquidity.

9. Credit Positioning

KOMIR’s credit position among Korean quasi-sovereigns is one in which standalone financials and business legacy risk are weaker than those of policy banks, while government support is far stronger than for commercial mining companies. KDB/KEXIM have clearer directness of support and financial policy functions, while KEPCO/KOGAS have stronger immediate essentiality in power and gas. KOMIR is a medium- to long-term policy institution for critical minerals and mine rehabilitation, and its legacy losses from overseas resource investments, negative equity, and market debt are more prominent.

Compared with commercial mining companies, KOMIR is not a mining major. Higher commodity prices do not necessarily translate straightforwardly into credit improvement; they affect the valuation of existing investments, recovery of losses, and the form of policy support. KOMIR is similar to public resource agencies such as JOGMEC, but as an issuer of market debt, its negative equity and refinancing risk are clearly visible as credit risks for investors.

This report does not take a definitive view on relative value. Market data, current spreads, Korean quasi-sovereign bonds of similar maturities, and curve comparisons with KDB/KEXIM/KEPCO/KOGAS/KNOC have not been confirmed. Relevant comparison axes are the directness of government support, the presence or absence of a government guarantee, standalone financials, short-term liquidity, overseas asset risk, issuance size and liquidity, sovereign linkage, and individual bond terms.

10. Key Credit Strengths and Constraints

Credit strengths are the close distance to the Korean government, the irreplaceability of policy mandates, access to international markets, and the scope for risk containment through policy redirection. 100% government ownership, KOMIR’s establishment, supervision, possible guarantees, subsidies, and possible residual loss assumption under the KOMIR Act, the support letter, and rating-agency support assessments together support A-category ratings and international bond-market access despite weak standalone financials. Stable access to critical minerals, mine rehabilitation, domestic mining support, strategic stockpiling, and support for private-sector overseas resource development are linked to Korea’s industrial policy and national security and are therefore difficult for the government to abandon easily.

Credit constraints are weak standalone financials, legacy overseas resource investments, the gap between government support and legal guarantee, policy redirection risk, and sovereign linkage. At end-2025, total equity remained negative KRW3.16 trillion, while operating losses, net losses, and negative operating cash flow persisted, and scheduled repayments of borrowings and bonds within one year reached KRW2.46 trillion. If Boleo, Cobre Panama, or Ambatovy deteriorate, earnings, capital, and the required amount of government support could be affected. Ordinary KOMIR bonds are not necessarily government-guaranteed, and any deterioration in Korea’s sovereign profile or government support stance would likely feed through to ratings and spreads even if standalone financials were unchanged.

11. Downside Scenarios and Monitoring Triggers

The most severe downside scenario for KOMIR would involve a simultaneous deterioration in standalone financials and a decline in the expectation of government support. Because KOMIR already has negative equity and negative operating cash flow, some continuation of losses by itself should not necessarily change the credit view materially. What matters is whether the scale becomes large enough to undermine the timeliness of government support, refinancing capacity, ratings, and access to the foreign-currency bond market.

Key downside triggers include a deterioration in Korea’s sovereign rating or outlook, weaker confidence in government ownership, policy mandates, KOMIR Act support provisions, capital injections, subsidies, or the support letter, additional losses related to Boleo, Cobre Panama, or Ambatovy, closure of short-term refinancing markets, renewed policy risk-taking, and weak individual bond terms. Scheduled repayments of borrowings and bonds within one year were KRW2.46 trillion at end-2025, far exceeding cash and current financial assets. If multiple markets deteriorated at the same time and the form of government support were unclear, liquidity risk could rise rapidly.

Monitoring items are Korea’s sovereign rating and outlook, government support and capital injections, operating cash flow and net income, borrowings and bond maturities, overseas investments, policy direction, and individual bond terms. Negative signals include delayed capital injections, subsidy reductions, widening operating cash flow deficits, increasing maturities within one year, renewed expansion of high-risk overseas investments or guarantees, and bond structures without a government guarantee or with weak covenants.

An improvement scenario would involve clear continuation of government support, gradual reduction of negative equity through capital injections or subsidies, stabilisation of overseas investment losses, improvement in operating cash flow, extension of near-term maturities, and a policy direction focused on private-sector support, stockpiling, recycling, and information support rather than high-risk direct investments. In particular, if risks related to Cobre Panama and Boleo are contained and KOMIR can strengthen its resource-security functions while avoiding new large-scale losses, the weakness of standalone financials would gradually be corrected.

12. Credit View and Monitoring Focus

At present, KOMIR can be treated as an upper A-category quasi-sovereign on a Korean government support-inclusive basis, but its standalone financial profile is fragile. The credit direction is viewed as broadly stable on a support-inclusive basis for the time being, while standalone risks remain due to negative operating cash flow, negative equity, near-term maturities, and legacy overseas investments. The April 2026 US dollar bond issuance is evidence of market access, but it does not mean that the refinancing of the entire near-term maturity profile has been automatically resolved.

For bond investors, the most important point is not to confuse the likelihood of government support with the legal protection of individual bonds. The likelihood of support for KOMIR is high, but the 2026 GMTN Notes are not guaranteed by the Korean government. Conditions for an improved credit view would include government capital injections or subsidies reducing negative equity, narrowing operating cash flow deficits, extension of near-term maturities, and containment of overseas investment risks such as Boleo and Cobre Panama. Deterioration would occur if a downgrade of Korea’s sovereign rating, a weaker assessment of government support, delays in capital injections or subsidies, additional losses from overseas resource investments, and closure of short-term refinancing markets coincided.

Short Summary & Conclusion

KOMIR is a government-related issuer in the mineral resources and mine rehabilitation sector that is 100% owned by the Korean government and is responsible for stable access to critical minerals, support for the domestic mining industry, mine rehabilitation, and the resolution of legacy overseas resource investments. Its credit profile is viewed as an upper A-category quasi-sovereign on a government support-inclusive basis, while standalone financials remain fragile, with negative equity, negative operating cash flow, and near-term maturities still present at end-2025. The central issue for investors is how to price the strong likelihood of Korean government support against the legal distinction that ordinary KOMIR bonds are not government-guaranteed.
