San Miguel Global Power (SMCGL), the Philippines’ largest power generator, faces a key refinancing event with the December 2026 call on its USD 683 million perpetual securities.

While earnings remain supported by long-term bilateral contracts, the credit profile is shaped by a coal-heavy portfolio, pass-through mechanisms, and a liability structure that weakens underlying coverage.

SMCGL operates ~5.7 GW (~20% of national capacity) and remains predominantly coal-based, with limited diversification and no defined transition plan. Revenue is supported by long-term PPAs with fuel cost pass-through, but the 2022 coal price shock showed that recovery is timing-dependent, leading to temporary earnings and liquidity pressure.

The primary constraint lies on the liability side. USD perpetuals form a significant share of funding, and when distributions are treated as fixed obligations, coverage falls materially below reported metrics, leaving limited headroom under stress. Coal concentration within an import-dependent system further links credit outcomes to commodity prices, supply risks, and evolving policy direction. Peers with more diversified portfolios and clearer transition pathways trade at tighter levels.

Current spreads show no clear transition-related premium and are largely driven by capital structure and market conditions. However, historical spread behaviour during the 2022 shock indicates state-dependent downside risk not fully reflected in current pricing. The December 2026 refinancing will test funding access and pricing, with focus on execution, cost of capital, and whether the issuer addresses portfolio concentration through disclosure, capital allocation, or transition strategy.
