- "Dividendo a cuenta" (interim dividend) mechanism in place

## S&P Regulated Utilities Assessment Framework

### Regulatory Advantage Factors
Based on the S&P methodology for regulated utilities:

1. **Regulatory stability**: Spain's electricity transmission benefits from EU-wide network codes and national regulatory framework (CNMC oversight). The regulatory period is typically 6 years with reasonable predictability.

2. **Tariff-setting procedures**: Revenue = RAB × WACC + OPEX + incentives. Spanish TSOs benefit from regulated returns with cost pass-through mechanisms.

3. **Financial stability**: Timely cost recovery through regulated tariffs; access to low-cost infrastructure financing.

4. **Regulatory independence**: CNMC operates with reasonable independence; EU regulatory framework provides additional stability layer.

### Scale, Scope and Diversity
- National electricity transmission system operator for Spain
- Monopoly position in core market
- Geographic concentration (primarily Spain) but with some international investments (equity method investments grew from €588m to €892m)
- Large-scale infrastructure with €9.6bn in PPE

### Operating Efficiency
- Depreciation and amortization: €545m (stable, slightly up from €522m)
- Employee benefits: €211m (up from €187m)
- Cost management appears in line with regulatory expectations

## Hybrid Bond Suitability Assessment

### Arguments for STRONGLY SUITABLE:

1. **Business Model Fit**: 
   - Pure regulated utility/infrastructure - exactly the profile S&P identifies as most suitable for hybrids
   - Natural monopoly with essential service provision
   - Highly visible, stable cash flows from regulated transmission tariffs

2. **Financial Profile**:
   - Investment grade characteristics (implied by business model and metrics)
   - Strong FFO generation: ~€1.57bn operating cash flow + €545m D&A = ~€2.1bn EBITDA proxy
   - Debt/EBITDA or FFO/debt metrics would likely support investment grade rating

3. **Capital Intensity and Funding Needs**:
   - €9.6bn PPE base with ongoing maintenance and expansion capex
   - €536m purchase of PPE/intangibles in 2022
   - Significant investing outflows: €1.64bn in 2022 (includes €305m group/associates investments)
   - Strong rationale for long-term, equity-like financing to match asset duration

4. **Hybrid Benefits**:
   - Hybrid issuance could materially improve adjusted leverage metrics
   - 50% equity credit from S&P for hybrid bonds would reduce reported leverage
   - FFO/debt improvement would support rating headroom

5. **Market Access and Credibility**:
   - Spanish blue-chip utility with established capital market access
   - State-linked ownership historically (though now more diversified)
   - Institutional investor familiarity with Spanish utility hybrids

6. **Refinancing Dynamics**:
   - Current financial liabilities of €1.71bn suggest ongoing refinancing needs
   - Long-term debt profile benefits from hybrid's extended tenor

### Potential Concerns (but not disqualifying):

1. **Strong equity base**: Equity improved significantly to €4.89bn (33% of assets) - this is actually positive for hybrid capacity
2. **Dividend distributions**: Active dividend policy (€1/share) but covered by earnings
3. **Slight profitability decline**: EPS down from €1.26 to €1.23, but minimal and within normal range for regulated utilities

### Comparison with Guidelines:

| Strongly Suitable Criteria | REDEIA Assessment |
|---------------------------|-------------------|
| Regulated/utility/infrastructure with highly visible cash flows | ✓ YES - Spanish TSO |
| Investment grade profile in BBB area | ✓ YES - implied by metrics and sector |
| Hybrid could materially improve adjusted leverage/FFO/debt | ✓ YES - significant debt base to optimize |
| Strong refinancing/capex/M&A funding rationale | ✓ YES - €1.6bn+ investing outflows, grid investments |
| High credibility of financial policy and market access | ✓ YES - established Spanish utility |
| Deteriorating financial metrics needing hybrid to preserve rating | Partial - stable to slightly soft, hybrid would improve headroom |

## Market Context (2022)

- Rising rate environment: 5Y swap at 1.726%, 10Y at 1.927%
- Corporate bond spreads widening (iBoxx non-fin IG at 2.295%)
- Hybrid issuance would be relatively attractive in this environment for issuer
- Subordinated debt delta of 0.2% suggests modest additional cost for hybrid structure

## Conclusion

REDEIA CORPORACION SA exhibits the classic profile of a **Strongly Suitable** hybrid bond issuer:

- Core regulated utility infrastructure business with natural monopoly characteristics
- Stable, predictable cash flows from regulated transmission activities
- Significant capital intensity requiring long-duration financing
- Strong investment grade credit profile that would benefit from hybrid equity credit
- Clear use of proceeds rationale (grid investment, refinancing, leverage optimization)
- Established market access and institutional credibility

The company's position as Spain's electricity TSO, with €9.6bn of regulated transmission assets and €1.57bn of operating cash flow generation, provides exactly the type of low-volatility, infrastructure-like cash flow profile that makes hybrid bonds an efficient and appropriate capital structure tool.
