1. Business Snapshot and Recent Developments

Momentive Performance Materials Inc. (“Momentive” or “MOMPER”) is a high-performance silicones and specialty materials company headquartered in Niskayuna, New York, and is currently an indirect wholly owned subsidiary of Korea’s KCC Corporation (“KCC”). For bond investors, the first point to clarify is that the reason for analysing Momentive in a Korean issuer context is not the location of its operating headquarters, but KCC’s ownership, support, and guarantee context. The operating business is a U.S.-headquartered global chemical company, and its financial disclosure is limited as a privately held subsidiary. At the same time, since 2024, three developments have changed the credit: KCC’s full ownership, debt repayment and refinancing in 2025, and the issuance of bonds guaranteed by Kookmin Bank. As a result, this is now a credit where investors need to analyse not only standalone business risk but also parent support and instrument-specific guarantees.

The business profile is relatively clear. Momentive is a specialty chemicals company that supplies silicones, silicone derivatives, specialty silanes, specialty fluids, elastomers, coatings, electronic materials, personal-care ingredients, and construction sealants. In its official company overview, the company states that it has more than 40 locations across more than 20 countries and serves more than 4,000 customers in over 100 countries. End-markets include agriculture, automotive, aerospace, electronics, personal care, consumer products, building and construction, specialty fluids, silanes, and additives. This is credit-supportive in the sense that the company is not a chemical producer dependent on a single product or customer. However, it is not a non-cyclical stable credit: materials cycles, prices, raw materials, capex, inventories, and regional demand all move in combination.

14 May 2024 was a major inflection point for credit analysis. On that date, Momentive announced the completion of its full acquisition by KCC, with minority shareholder SJL Partners LLC exiting. KCC had already held a majority stake since 2020, but full ownership shifted Momentive from a co-owned company with a private-equity element to something closer to a strategic subsidiary of the KCC group. In July 2024, S&P Global Ratings also raised its assessment of Momentive’s position within the KCC group, citing KCC’s full ownership, liquidity support from KCC, past debt guarantees, and the potential for future debt-repayment support. This does not mean that the business itself suddenly became low-risk. Rather, the nature of the sponsor changed, making external support more likely to be available for debt repayment.

The most important development in 2025 was debt repayment and refinancing. In its publication dated 7 October 2025, S&P assigned an A+ issue rating to Momentive’s proposed U.S. dollar senior unsecured bonds, based on the irrevocable and unconditional guarantee from Kookmin Bank and by substituting the guarantor’s rating. In the same report, S&P assigned Momentive a BB/Stable issuer rating and expected Momentive’s debt to EBITDA to improve to about 4x in 2025, on a pro forma basis after the July 2025 debt repayment, from more than 6x in 2024. The proceeds were expected to be used to repay about USD536 million of existing Term Loan B balances and about USD150 million of ABL borrowings outstanding as of 30 September 2025, among other uses. This should reduce interest burden and ABL utilisation, but S&P still expected free cash flow to remain negative in 2025 due to elevated capex.

These developments show that MOMPER’s credit analysis needs to be divided into two layers. The first layer is the business and financial risk of Momentive / MOM Holding Company, which should be analysed as a BB-rated specialty chemicals credit through the lenses of the silicone cycle, leverage, FCF, liquidity, and KCC support. The second layer is the guarantee structure of individual bonds. For bonds unconditionally and irrevocably guaranteed by Kookmin Bank, investors need to analyse not only Momentive’s own credit quality but also the guarantor’s credit quality and the wording of the guarantee. The A+ rating reflects this second layer of protection; it does not mean that Momentive on a standalone basis has an A-category financial profile.

The most recent public financial information is centred not on standalone Momentive but on MOM Holding Company and the silicone segment as disclosed in KCC’s consolidated reporting. KCC’s 2025 annual report shows that MOM Holding Company and its subsidiaries recorded revenue of KRW3,075.6 billion, assets of KRW4,151.3 billion, liabilities of KRW2,617.7 billion, and a net loss of KRW556.5 billion in 2025. KCC’s silicone segment recorded segment revenue of KRW4,302.2 billion and operating profit of KRW81.0 billion in 2025, with operating profit improving from KRW72.96 billion in 2024. However, the segment operating margin remains low, and the MOM group reported a net loss. It would therefore be inappropriate to infer credit improvement solely from the scale of the business platform.

Accordingly, the most natural view of MOMPER at this stage is that default risk has receded materially due to KCC’s full ownership and the 2025 support and refinancing, while the standalone business remains a specialty chemicals credit with a history of high leverage, negative FCF, a heavy capex burden, and limited public disclosure. The first questions for investors are not “Is Momentive a good company?” but “How far has the standalone repayment capacity recovered excluding KCC support and bank guarantees?” and “Whose credit is the specific bond actually taking?”

2. Industry Position and Franchise Strength

Momentive’s business platform is supported by the broad applications of silicones and silicone derivatives. Silicones are used in applications requiring heat resistance, flexibility, electrical insulation, weatherability, water repellency, biocompatibility, and similar properties. End-markets are broad, ranging from relatively general applications such as construction sealants and coatings to specialty applications such as electronic materials, thermal management materials, aerospace, automotive, batteries, personal care, and agricultural additives. Momentive’s strength lies in its ability to supply these broad end-markets through a combination of product design, formulation, customer qualification, regulatory compliance, and application development.

For credit, this breadth has two implications. First, a downturn in a single end-market is less likely to hit companywide revenue directly. Even if housing and construction are weak, electronics, personal care, automotive, aerospace, and industrial applications may move differently. Second, the more specialised the application, the more the product is embedded in the customer’s product design and manufacturing process, making pricing more defensible than in pure commodities. In chemical credit analysis, not only volume and price but also whether a product is embedded in customer qualification, how long substitution would take, and how demanding regulatory and quality requirements are matter. In this respect, Momentive has a stronger franchise than a mere materials trader or commodity chemicals producer.

At the same time, the silicone market has a clear cycle. Demand is linked to construction, automotive, electronics, industrial production, and consumer goods, while supply-side factors such as global production capacity, including in China, raw materials, energy, inventories, and logistics affect prices. In 2023–2024, the silicone industry as a whole faced weak demand and oversupply concerns. S&P also viewed Momentive’s capital structure, high cash interest burden, and negative FCF as significant constraints in 2024. Momentive’s business platform therefore combines the “stickiness” of specialty chemicals with the volatility of a materials cycle.

The combination with KCC may reinforce the business platform. KCC is a Korean chemicals company with building materials, paints, specialty materials, and silicones, and KCC’s annual report states that the group vertically integrated its silicone business under MOM Holding Company in 2021. By integrating KCC’s Asian production, sales, and R&D base with Momentive’s global customer and technology base, including in the U.S. and Europe, there is potential for synergies in scale, geographic diversification, product complementarity, procurement, and R&D. However, synergies do not automatically improve credit quality. They become a substantive improvement for bondholders only when they translate into operating profit, working capital, FCF, and debt reduction.

Momentive’s official 2024 Sustainability Report indicates consolidated revenue of around USD2.2 billion in 2024 and shows revenue diversified across the Americas, Europe, and Asia Pacific. However, this is a non-financial and sustainability-context document, not a substitute for audited financial metrics. For credit analysis, KCC’s annual-report figures for MOM Holding Company and the silicone segment should be treated as the core financial reference, while the Sustainability Report is more appropriately used as supplementary evidence on product, regional, and customer breadth.

In peer comparison, Momentive is one of the major global players in the broad silicone and specialty materials market, in which Dow, Wacker Chemie, Shin-Etsu Chemical, Elkem, Evonik, and KCC are also involved. However, public information alone does not allow confirmation of exact global market share, application-specific ranking, or margin comparison with peers. This report therefore treats phrases such as “one of the world’s largest” or “a major player” as broad scale indicators based on company and rating-agency materials, and does not make numerical market-share-based ranking assertions.

The channels through which this business platform supports credit quality are pricing power, customer retention, application diversification, and capital-market access. The higher the share of specialty applications, the more customers value quality, supply stability, and regulatory compliance, and the less likely they are to switch suppliers based on price alone. This helps protect margins even within a materials cycle. By contrast, in general-purpose silicones and applications more exposed to construction and consumer products, demand weakness, inventory destocking, and price declines can flow through to operating profit quickly. Momentive’s franchise supports the downside of its credit quality, but it is not stable enough on its own to justify a highly leveraged capital structure.

3. Segment Assessment

Standalone segment revenue and profit for Momentive are not sufficiently disclosed in the materials reviewed for this report. Therefore, the segment assessment is based on the company’s official business areas and KCC’s silicone segment disclosure. The purpose is not to fill non-disclosed figures with estimates, but to identify which revenue sources are more stable and which areas are sensitive to cycles, capex, and price movements.

Momentive’s product groups can be broadly viewed as basic silicones, formulated and specialty silicones, silanes and additives, electronic, thermal-management and high-performance materials, and applications for construction, consumer goods, and personal care. Basic silicones require scale and supply stability and are more exposed to raw materials, energy, and production-capacity cycles. Formulated and specialty silicones, silanes, and electronic materials are more likely to capture value from application development and customer qualification, but they require R&D, quality control, regulatory compliance, and capex. Construction and consumer-goods applications may offer large volumes, but they are more tied to the economic cycle, housing investment, consumer spending, and channel inventories.

KCC’s disclosure shows that the silicone segment recorded segment revenue of KRW4,302.2 billion, external revenue of KRW3,067.1 billion, and operating profit of KRW81.05 billion in 2025. In 2024, it recorded segment revenue of KRW4,210.3 billion, external revenue of KRW2,995.3 billion, and operating profit of KRW72.96 billion. Revenue was broadly flat to slightly higher, and operating profit improved, but the operating margin was less than 2% of segment revenue. This indicates that while the silicone business has scale, current profitability is still not particularly thick. In addition, MOM Holding Company and its subsidiaries reported a net loss in 2025, suggesting that improvement at the operating level may not yet have fully translated into net income or FCF improvement.

The three revenue figures shown here are not the same figure expressed in different currencies. The approximately USD2.2 billion of consolidated revenue in Momentive’s 2024 Sustainability Report indicates the business scale as presented in Momentive’s official materials, but it is not a table of audited debt-service capacity. KCC silicone segment revenue of KRW4,302.2 billion is the full silicone business segment within KCC and is not standalone Momentive Inc. MOM Holding Company and subsidiaries’ KRW3,075.6 billion revenue is the closest public financial scope to the Momentive-related group among the materials reviewed, but even this does not directly show issuer-level cash, debt, or FCF. Therefore, repayment-capacity analysis should place the MOM Holding summary financials at the centre, use the KCC silicone segment as a reference for business earnings power and importance within the parent, and use Momentive’s official revenue as a reference for business scale and geographic diversification.

The main point from this table is that the Momentive / KCC silicone business is “large in scale, but not yet clearly strong in financial headroom.” Positive and improving operating profit is favourable, but the important metric is FCF after depreciation, capex, interest, FX, and restructuring expenses. S&P’s expectation of continued negative FCF in 2025 reflects this capital intensity and the weight of growth and maintenance investment.

By business area, the segments most likely to support credit quality are specialty applications where customer qualification and application development matter. Electronic materials, thermal management, aerospace, automotive, healthcare, and personal care require high quality standards and are more likely to be embedded in customer specifications. These applications are less likely to be dragged into simple price competition and may retain volume and price relatively well even in a weak economy. By contrast, construction and general-purpose sealants, basic silicones, and general-purpose fluids are more exposed to price cycles and inventory adjustments. Public information does not allow confirmation of margins by application, so investors should monitor any company or rating-agency disclosure on the “specialty product mix,” “price, volume and mix,” and demand by customer and region.

Geographic diversification is also present, but it does not eliminate risk. Revenue split across the Americas, Europe, and Asia Pacific reduces dependence on any single country’s economy. At the same time, European energy and chemicals regulation, Chinese oversupply, the U.S. construction and automotive cycles, and Asian electronics and consumer-goods demand each bring different risks. FX is also relevant, with Korean won at the KCC consolidated level and U.S. dollar, euro, renminbi, and other currencies at the Momentive business level. Business diversification supports credit quality, but financial analysis still needs to account for currency, inventory, and regional demand volatility.

4. Financial Profile and Analysis

Financial analysis needs to separate three scopes. The first is Momentive Performance Materials Inc. itself, which is the most important as the bond issuer, but standalone financials were not sufficiently available in the public information reviewed. The second is MOM Holding Company and its subsidiaries, the closest scope for which summary financials are available in KCC’s annual report. The third is KCC consolidated and the KCC silicone segment, which are needed to assess the parent’s support capacity and the context of business integration. Confusing these scopes may lead either to overestimating Momentive’s standalone repayment capacity or to overlooking the protection of Kookmin Bank-guaranteed bonds.

The 2025 figures for MOM Holding Company and its subsidiaries show both business scale and financial constraints. Revenue was KRW3,075.6 billion, assets were KRW4,151.3 billion, liabilities were KRW2,617.7 billion, and equity was KRW1,533.6 billion. Liabilities-to-equity is approximately 1.7x on a simple calculation, but this is total accounting liabilities and not a net interest-bearing debt ratio. Net loss was KRW556.5 billion, and without details of non-operating expenses, finance costs, FX, impairments, restructuring, and tax effects, the loss cannot be explained solely by business profitability. Even so, the size of the net loss indicates that the Momentive-related group is not yet at a stage where it can comfortably reduce debt using only internally generated funds.

KCC’s silicone segment shows modest improvement at the operating level. Operating profit in 2025 was KRW81.05 billion, up from KRW72.96 billion in 2024. Segment revenue also increased from KRW4,210.3 billion to KRW4,302.2 billion. However, operating margins are low, and given the capital intensity of the business, a modest decline in pricing, lower utilisation, inventory valuation effects, or increases in raw-material and logistics costs could compress earnings. The company has strengths as a specialty chemicals business, but based on currently available public financials it is difficult to describe it as a company with thick margins that can comfortably absorb debt repayment.

At the KCC consolidated level, the parent’s support capacity has strengthened. According to Yonhap’s 5 February 2026 report, KCC recorded 2025 revenue of KRW6.48 trillion, operating profit of KRW427.6 billion, and net income of KRW1.54 trillion. KCC’s annual report shows consolidated liabilities of KRW8.98 trillion and equity of KRW7.82 trillion at end-2025, with the debt-to-equity ratio declining to 114.8% from 154.6% at end-2024. However, this improvement also includes effects from changes in the valuation model for land, right-of-use assets, and investment property, as well as the value of shareholdings. It should not be explained solely by operating cash-flow improvement. The parent’s asset value and capital headroom are supportive, but KCC itself also has substantial liabilities and exposure to investment-asset valuation movements.

S&P’s view provides an important reference point for interpreting the financials. In July 2024, S&P lowered Momentive’s standalone credit profile to ccc+ while raising the issuer rating to B+ to reflect KCC group support. This means that the standalone capital structure and FCF were weak, but parent support was expected. By October 2025, after parent support and debt repayment, the issuer rating was BB/Stable, and S&P expected 2025 debt to EBITDA to improve to about 4x. In other words, the financial trajectory is clearly improving, but the improvement depends materially on KCC support and the refinancing structure, not simply on organic recovery in the business.

The table below consolidates available financial, debt, and liquidity indicators with unconfirmed items. For an issuer with significant disclosure constraints, it is important not to leave unconfirmed items blank, but to specify which judgments remain provisional.

The conclusion from this financial profile is that Momentive’s credit quality has improved but is not yet clearly strong on a standalone basis. The business has meaningful revenue scale, the KCC silicone segment is operating-profit positive, and leverage is expected to decline materially after debt repayment. At the same time, the MOM group’s net loss, S&P’s expectation of negative FCF, the capex burden, disclosure limitations, and reliance on guarantee structures remain. Therefore, Momentive’s own credit quality should be analysed cautiously as a BB-area corporate issuer, while A+ guaranteed bonds should be treated separately as instruments taking guarantor credit.

5. Structural Considerations for Bondholders

From the bondholder perspective, the most important point is to distinguish between issuer, parent, and guarantor. Momentive Performance Materials Inc. appears as the bond issuer, but it is an indirect subsidiary of MOM Holding Company, and MOM Holding Company is fully controlled by KCC. KCC’s 2025 annual report lists numerous Momentive-related entities, including MPM Holdings Inc., MPM Intermediate Holdings Inc., Momentive Performance Materials Inc., Momentive Performance Materials Worldwide LLC, and Momentive Performance Materials USA LLC, as wholly owned subsidiaries under MOM Holding Company. Legally, investors need to confirm which entity owes the debt, which entity provides guarantees, and which assets and cash flows creditors can access.

For the new U.S. dollar bonds in October 2025, S&P assigned an A+ rating to the proposed notes guaranteed by Kookmin Bank. Based on the materials reviewed for the proposed notes, S&P treated the guarantee as irrevocable and unconditional and as securing timely payment, and allowed substitution to the guarantor’s rating. This is highly important for bondholders. The reason is that even if debt is issued under the Momentive name, instruments with a Kookmin Bank guarantee and those relying only on KCC’s strategic importance have fundamentally different sources of recovery and credit quality. When analysing A+ rated bonds, investors need to focus more on the guarantor’s credit quality, guarantee agreement, payment terms, governing law, claim procedure, and exclusions than on Momentive’s BB rating. Until the final Offering Circular is reviewed, the assessment of instrument-specific protection remains provisional.

By contrast, KCC’s ownership and support are not the same as a legal guarantee. KCC became the full owner in 2024 and provided support in 2025 through capital injections into MOM and debt repayment support. Korean media reported that KCC injected around KRW1 trillion into MOM Holding Company and repaid Momentive-related acquisition financing, expecting annual interest savings of more than KRW100 billion. A separate report stated that approximately KRW685.9 billion of debt guarantees for Momentive Performance Materials were released following full repayment of the borrowings. These are positive indicators of KCC’s willingness to support. However, past support and strategic importance do not legally guarantee payment on individual bonds. Guaranteed bonds and unguaranteed bonds, and bank guarantees and parent support, must be kept separate.

This structure raises several legal questions for investors. First, the final Offering Circular for the USD700 million Senior Unsecured Guaranteed Notes issued in 2025 needs to confirm whether Kookmin Bank is the only guarantor, whether KCC or group-company guarantees are present, and whether the guarantee is an unconditional, irrevocable payment guarantee or closer to a guarantee letter or standby letter-of-credit structure. Second, investors need to confirm where the bonds rank as unsecured obligations of Momentive Inc. relative to bank borrowings, ABL facilities, secured debt, leases, local subsidiary debt, tax, pension, and environmental liabilities. Third, investors need to assess how much protection is provided by change of control, negative pledge, restricted payments, additional debt, secured debt, asset sales, related-party transactions, cross-default, and similar covenants.

As of the date of this report, the final Offering Circular text has not been located in public sources. Therefore, covenant protection for the specific bonds is treated as an unconfirmed item. Greenberg Traurig’s 12 November 2025 release confirms that Momentive issued USD700 million of Rule 144A / Reg S Senior Unsecured Guaranteed Notes, priced them on 16 October 2025, closed them on 22 October, listed them on the SGX, and used BNP Paribas, Citigroup, and Mizuho as joint bookrunners. However, while a law-firm release is useful for confirming the outline of the issuance, it is not a substitute for the guarantee language or covenants.

Structurally, Momentive bondholders are distinguishing at least three credits. The first is the business credit of Momentive / MOM Holding, centred on silicone earnings, FCF, leverage, and liquidity. The second is KCC parent-support credit, centred on full ownership, strategic importance, past support record, and KCC’s own capital and liquidity. The third is the guarantee credit of Kookmin Bank-guaranteed bonds, where the guarantor’s A+ rating becomes central if the guarantee agreement is effective. Investment decisions should make clear how much they rely on each layer.

6. Capital Structure, Liquidity and Funding

The 2025 refinancing likely improved Momentive’s liquidity and capital structure materially. S&P expected the proposed bond issuance in October 2025 to repay about USD536 million of Term Loan B balances and about USD150 million of ABL borrowings, leaving no borrowings outstanding under the ABL. The ABL borrowing base was reported at about USD297 million as of June 2025. This would reduce secured and floating-rate bank borrowings and ABL utilisation in the near term and replace them with bond funding supported by a bank guarantee. Lower interest costs, better maturity distribution, and restored ABL headroom are positive for liquidity.

However, refinancing does not magically eliminate leverage. S&P viewed the transaction as leverage-neutral while positive for interest expense and FCF. In other words, it can change the form of debt, lower the interest cost, and eliminate ABL utilisation, but it does not necessarily materially reduce total debt. KCC support for debt repayment in July 2025 appears to have contributed to leverage reduction, while the guaranteed new bonds issued in October 2025 were primarily a refinancing of existing debt. Therefore, further credit improvement will depend on how far operating cash flow after the refinancing can absorb capex and interest and actually reduce debt.

Liquidity support comes from parent KCC and the bank-guarantee structure. KCC provided a capital injection into MOM and debt repayment support in 2025, and reports indicate that KCC also secured funding through instruments such as exchangeable bonds using shareholdings. KCC’s consolidated equity increased materially at end-2025, and its debt-to-equity ratio declined. These are supplementary positives for support capacity. At the same time, a strict assessment of KCC’s support capacity would require confirmation of KCC standalone and consolidated cash, short-term debt, maturity schedule, unused committed lines, ratings, and dependence on the value of shareholdings; this report has not completed that level of detailed verification. KCC is a large company with building materials, paints, specialty materials, and silicones, but it is also affected by its own investments, dividends, borrowings, shareholding values, interest rates, and the Korean won. Whether support for Momentive continues should be monitored through Momentive’s strategic importance to KCC and KCC’s own financial headroom.

The main liquidity constraint is that FCF is not yet sufficient. S&P expects Momentive’s FCF to remain negative in 2025, even after lower interest expense, because capex remains high. The silicone business requires production facilities, environmental and safety investments, quality control, R&D, customer qualification, and maintenance of a global footprint. Large depreciation raises EBITDA, but if actual maintenance and growth capex are also large, the cash left after interest and capex can be thin. Momentive should therefore be analysed using EBITDA-to-cash interest, operating cash flow, capex, FCF, and ABL availability together, rather than EBITDA multiples alone.

The maturity profile cannot be fully established from the public materials reviewed. The final maturity, coupon, redemption provisions, residual debt, ABL facility terms, other local borrowings, leases, secured debt, and environmental and pension liabilities remain unconfirmed. S&P’s materials confirm the direction of repayment for the Term Loan B and ABL borrowings, but do not provide sufficient detail on post-transaction total debt, cash, unused capacity, committed lines, guarantee costs, and restrictions. The OC and latest financials should be reviewed for any individual investment.

Funding access appears to have improved materially through the 2025 transaction. The ability to issue U.S. dollar bonds listed on SGX with a Kookmin Bank guarantee broadens the investor base and improves funding stability. The involvement of BNP Paribas, Citigroup, and Mizuho as bookrunners also supports international capital-market access. However, this access is supported by the bank guarantee and KCC context, not by Momentive’s standalone credit quality. Whether guaranteed funding remains available, what the guarantee cost is, and whether the guarantor’s or KCC’s willingness changes are important monitoring points.

7. Rating Agency View

S&P’s rating history captures MOMPER’s credit story well. In July 2024, S&P raised Momentive’s issuer rating from B to B+. At the same time, it lowered the standalone credit profile from b- to ccc+. This may look contradictory, but the actual structure is that standalone credit weakened while KCC’s full ownership and potential support became more important, resulting in a higher final issuer rating. S&P viewed Momentive as a strategically important subsidiary within the KCC group, citing KCC’s full ownership, a USD100 million shareholder loan, past debt guarantees, and the potential for future debt-repayment support.

In 2025, S&P’s view improved further. In its 7 October 2025 release, S&P assigned Momentive a BB/Stable issuer rating and referenced the August 2025 related research in which the rating had been raised to BB due to parent support and debt repayment. S&P expected debt to EBITDA to improve to about 4x in 2025 on a pro forma basis after the July 2025 debt repayment, from more than 6x in 2024. This is a significant credit improvement. At the same time, S&P also stated that FCF was expected to remain negative in 2025, so the rating improvement should not be read as purely self-driven improvement.

At the individual bond level, S&P assigned an A+ rating to the proposed bonds guaranteed by Kookmin Bank. This A+ is much higher than Momentive’s BB issuer rating. The reason is that S&P viewed the Kookmin Bank guarantee as unconditional and irrevocable and as securing timely payment. This rating gap is highly important for investors. The risk of guaranteed bonds depends not only on deterioration in Momentive’s business, but also on the validity of the guarantee agreement, the guarantor’s credit quality, the guarantee claim process, sanctions, jurisdiction, and contractual exceptions. Conversely, for Momentive bonds that are not guaranteed or obligations outside the scope of the bank guarantee, the A+ rating should not be used as the reference.

The latest primary releases from Moody’s and Fitch were not sufficiently confirmed in this work. Past public or republished information indicates that Momentive had at times been rated around B1 or similar speculative-grade levels, and parent support and business improvement were review factors in 2024. However, this report does not assert unconfirmed latest ratings. Rating agencies may differ in their incorporation of parent support, treatment of bank guarantees, recovery assumptions, and assessment of standalone credit. Investors should review each agency’s latest primary text before investing.

The rating-agency view and the view in this report are broadly aligned. Momentive has a business franchise, but standalone leverage and FCF weakness remain. Credit improvement depends materially on KCC full ownership, debt repayment, and bank-guaranteed refinancing. Therefore, excluding guaranteed bonds, a conservative view is to treat the issuer as a BB-category specialty chemicals credit supported by parent support, not as a stable business company close to investment grade.

8. Credit Positioning

Because market data are not available, this report does not assess MOMPER bond spreads, yields, OAS, prices, maturity comparisons, or relative value. The Credit Positioning section instead places the credit based on fundamentals and structure. In conclusion, Momentive’s business credit should be separated into a BB-category credit including KCC support, while bank-guaranteed bonds should be treated as high investment-grade instruments close to guarantor credit.

As a specialty chemicals company, Momentive has a large-scale business platform, but its financial profile is far from that of upper investment-grade peers. Large chemical companies such as Dow, Shin-Etsu, Wacker, and Evonik are typically public companies with greater transparency and more stable business portfolios, leverage, liquidity, and ratings. Momentive is privately held, depends on financial disclosure through MOM Holding and KCC, and has weak FCF. Therefore, scale alone should not place Momentive alongside large IG chemical peers.

On the other hand, compared with weaker loan-heavy chemical credits, Momentive has the major differentiating factor of parent support. KCC, as the full owner, strengthened support in 2024–2025 and executed debt repayment and refinancing. S&P’s incorporation of multiple notches of support based on strategic importance shows that Momentive has shifted from a private-equity-owned company with standalone sponsor risk to a group company supported by a strategic parent. This is an important relative support factor within the BB category.

From this positioning, investors considering MOMPER should first decompose which credit the specific bond is taking. For guaranteed bonds, the legal certainty of the bank guarantee and the guarantor’s credit are central. For debt that is not guaranteed or where the guarantee scope is limited, the focus should be Momentive’s business credit, KCC support, leverage, FCF, and liquidity. Investors should not compare guaranteed bonds as though they were Momentive standalone spreads, nor treat unguaranteed bonds as equivalent to bank-guaranteed bonds.

9. Key Credit Strengths and Constraints

The first credit strength is that Momentive is a real global specialty materials company. Silicones and silicone derivatives are used across a wide range of industries, and Momentive has locations, customers, applications, and an R&D base. In specialty applications, customer qualification and quality requirements create barriers to entry, making the products less easy to replace on price alone. This provides a foundation that can support a leveraged capital structure.

The second strength is KCC’s full ownership and support record. KCC became the full owner in 2024 and, in 2025, provided a capital injection into MOM, repaid Momentive-related debt, and supported the refinancing. S&P incorporates this support into the issuer rating. Silicone is a growth and strategic business for KCC, and KCC is unlikely to have a strong incentive to separate from Momentive easily. Parent support is an important buffer against a sharp deterioration in credit quality.

The third strength is the capital-structure improvement in 2025. Based on S&P’s expectations, debt to EBITDA should improve to about 4x in 2025 from more than 6x in 2024. Repayment of the Term Loan B and ABL borrowings, refinancing into bank-guaranteed bonds, lower interest expense, and elimination of ABL utilisation are positive for liquidity and interest coverage. For bonds guaranteed by Kookmin Bank, there may be instrument-level protection materially stronger than issuer credit.

The first constraint is limited public financial disclosure for standalone Momentive. The most important issuer-level items for bond investors—operating CF, FCF, cash, debt, maturity schedule, unused capacity, covenants, collateral, guarantees, subsidiary-level debt, environmental liabilities, and pension liabilities—are not sufficiently visible from public information alone. KCC and MOM Holding disclosures are useful, but they are not substitutes for issuer standalone financials.

The second constraint is FCF and capex. S&P expects FCF to remain negative in 2025. Even if operating profit improves, debt reduction will be difficult if depreciation, capex, R&D, safety and environmental investment, and growth investment remain heavy. In chemical companies, underestimating maintenance capex leads to overestimating repayment capacity. For Momentive, investors need to keep monitoring whether FCF after capex turns positive, not just EBITDA leverage.

The third constraint is the materials cycle. Silicone prices are sensitive to the balance between demand and supply capacity. If oversupply, including from China, weak construction, automotive and electronics demand, inventory destocking, raw-material and energy costs, logistics costs, and regulatory compliance expenses worsen simultaneously, operating profit and working capital can come under pressure. Momentive’s specialty applications are supportive, but they do not fully immunise the whole company.

The fourth constraint is dependence on parent support. KCC support is a major strength at present, but the fact that the credit assessment depends on support is also a constraint. If KCC’s own earnings, debt, shareholding values, investment policy, dividends, or capital-market access deteriorate, its capacity or priority for supporting Momentive could change. KCC support is also not a legal guarantee and should not be confused with contractual protection for individual bonds.

10. Downside Scenarios and Monitoring Triggers

The most realistic downside scenario is one in which the silicone market recovery is delayed and price, volume, and mix do not improve, while capex and interest burden remain. In that case, operating profit would remain only modestly positive, EBITDA would be generated, but FCF would not turn positive. If FCF remains persistently negative, debt reduction will continue to depend on KCC support, asset sales, or refinancing. From a rating perspective, if debt to EBITDA does not improve to the approximately 4x level expected by S&P, or if it improves and then returns to the 5x area, rating headroom within the BB category would narrow. Investors should also raise caution if FCF breakeven remains out of sight beyond 2026, ABL borrowings rise again materially, or the operating margin in the KCC silicone segment declines again.

The second downside scenario is a weakening of KCC’s support capacity or willingness. As long as KCC continues to support Momentive as a strategic business, Momentive’s liquidity risk should remain contained. However, if KCC’s own performance deteriorates, shareholding values decline, interest rates rise, Korean capital markets weaken, other businesses require funds, or dividend and capital policy change, the timing and scale of support could be constrained. Because parent support is an important component of credit quality, KCC’s consolidated financials and ratings are monitoring items for Momentive.

The third downside scenario is misreading the guarantee structure. If investors incorrectly apply the A+ rating of Kookmin Bank-guaranteed bonds to all Momentive debt, they may overvalue unguaranteed or out-of-scope obligations. Even for guaranteed bonds, failing to review the guarantee language, claim process, payment timing, governing law, guarantor obligations, exclusions, tax, sanctions, and regulatory risks could lead to a misreading of the actual protection. This is not itself a credit event, but it is an important structural risk for investment decisions.

The fourth downside scenario is chemical-sector-specific operational and regulatory risk. In silicones and specialty chemicals, environmental, safety, emissions, chemical-substance regulation, production shutdowns, accidents, litigation, and product-quality issues can lead to shutdowns, compensation, capex, customer losses, and regulatory compliance costs. Momentive has a global footprint, so it is exposed to regulation across regions. Public materials do not allow sufficient confirmation of environmental liabilities or litigation details, so annual reports, rating reports, and OC risk factors should be monitored continuously.

Monitoring indicators should begin with revenue, operating profit, EBITDA, operating CF, capex, FCF, cash, gross debt, net debt, short-term debt, ABL availability, and EBITDA-to-cash interest for MOM Holding / Momentive-related entities. Next, investors should monitor KCC silicone segment operating margin, depreciation, internal and external revenue, regional revenue, and KCC consolidated leverage and liquidity. On ratings, investors should monitor S&P, Moody’s, and Fitch issuer ratings for Momentive, KCC ratings, Kookmin Bank ratings, and guaranteed-bond ratings. Structurally, the final OC for the 2025 bonds, guarantee wording, covenants, change of control, collateral, and additional-debt limitations should be reviewed. In addition, if KCC support is stopped or reduced, KCC or Kookmin Bank is downgraded, the guarantor changes, or the guarantee scope is limited, the bond assessment needs to be reviewed even if Momentive’s operating numbers have not changed materially.

11. Credit View and Monitoring Focus

Momentive’s issuer credit quality has improved to the BB category including KCC support, but it is not at a level where it should be viewed as a strong standalone investment-grade operating company. Current credit quality is supported by a major global silicone and specialty materials franchise, KCC’s full ownership and support record, debt repayment and refinancing in 2025, and interest and liquidity improvement from bank-guaranteed funding. The credit direction clearly improved from 2024 to 2025, but further improvement from here depends on recovery in business profit and FCF; it is not at a stage where support and refinancing alone can drive another step-up. The probability of rapid credit deterioration is not high while KCC support and guaranteed refinancing remain in place, but it is also not low enough to be comfortable on an unguaranteed basis, given negative FCF and the remaining materials-cycle exposure.

For investors, the central judgment is which credit the purchased bond is taking. If a bond is covered by an unconditional and irrevocable guarantee from Kookmin Bank, the main credit risk shifts toward guarantor credit and the validity of the guarantee agreement. By contrast, for unguaranteed or out-of-scope exposure to Momentive itself or the MOM group, the credit should be analysed as a BB-category specialty chemicals credit, with significant weight placed on leverage, FCF, KCC support, the silicone cycle, and standalone disclosure constraints. The rating of A+ guaranteed bonds should not be extended to Momentive’s overall issuer credit.

The strongest support for the current credit view is that KCC became the full owner in 2024 and actually injected funds and advanced debt repayment and refinancing in 2025. This is not merely support potential; it is a support record. S&P’s upgrade of Momentive to BB/Stable and its expectation of debt to EBITDA improving to about 4x also indicate lower near-term refinancing risk. However, the KCC silicone segment’s margins are thin, MOM Holding and its subsidiaries reported a net loss in 2025, and S&P also expects negative FCF. To confirm self-sustaining credit improvement, investors need to see operating-margin recovery, FCF breakeven, and substantive debt reduction from 2026 onward.

Monitoring should first focus on the continuity of KCC support. Investors should review KCC’s results, leverage, funding, shareholding values, the strategic positioning of the silicone business, and any additional capital injections or guarantees for Momentive. Support has been demonstrated, but support capacity requires further confirmation of KCC’s cash, short-term debt, maturity schedule, ratings, unused lines, and sensitivity to listed-share valuations. Second, investors should monitor Momentive / MOM FCF. The key question is whether cash remains after capex, interest, working capital, and refinancing costs, not just whether operating profit or EBITDA is positive. Third, investors should confirm the contract for the guaranteed bonds. The guarantee content assessed by S&P for the proposed bonds is strong, but without obtaining the final OC and reviewing the guarantor, guarantee scope, redemption, covenants, events of default, change of control, and additional-debt restrictions, instrument-specific investment judgment remains provisional.

Conditions for a further improvement in the credit view would include Momentive / MOM restoring operating margins, turning FCF positive, and showing a path to gradual debt reduction without KCC support. If leverage falls further from S&P’s expected approximately 4x level and liquidity is confirmed without dependence on ABL or short-term borrowings, stability within the BB category would improve. Conversely, if silicone market conditions deteriorate again, FCF remains negative, or questions arise over KCC’s support capacity or willingness, Momentive’s issuer credit could come under pressure again. For guaranteed bonds, changes in the guarantor’s rating or the guarantee agreement could be more important credit events than changes in Momentive’s business.

12. Short Summary & Conclusion

Momentive Performance Materials is a global high-performance silicone and specialty materials company under KCC, and its credit quality improved after KCC’s full ownership in 2024 and debt repayment and refinancing in 2025. However, the MOM group still reported a net loss in 2025, and S&P expects negative FCF, so the issuer credit should be viewed as a BB-category credit including KCC support. Bonds guaranteed by Kookmin Bank depend materially on guarantor credit, so investors must separate Momentive’s issuer credit from instrument-specific guarantees.
