Momentive Performance Materials Inc. (MOMPER)

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.
