# Analysis of Naturgy's Hybrid Bond Capacity vs. S&P Global Ratings Cap

## Step 1: Calculate Current Capital Structure (as of 2023-01-01)

**Equity:**
- Equity Attributable to Owners of Parent: €7,574M
- Noncontrolling Interests: €2,405M
- **Total Equity: €9,979M**

**Debt:**
- Long-term Borrowings: €12,689M
- Current Borrowings: €2,110M
- Lease Liabilities (non-current): €1,309M
- Lease Liabilities (current): €177M
- Other Financial Liabilities: €1,001M
- **Total Debt: €17,286M**

**Total Adjusted Capital (before hybrids):**
- €9,979M + €17,286M = **€27,265M**

## Step 2: Apply S&P Global Ratings' 15% Cap

S&P's rule limits equity credit on hybrids to 15% of total adjusted capital. This means:

**Maximum equity credit from hybrids:**
- 15% × €27,265M = **€4,090M**

## Step 3: Assess Naturgy's Financial Position

**Key Metrics:**

| Metric | Value | Assessment |
|--------|-------|------------|
| Debt/Total Capital | 63.4% | High leverage |
| Interest Coverage (EBIT/Interest) | 3.69x | Moderate |
| Net Debt | ~€13.3B | Significant |
| Leverage Ratio (Net Debt/EBITDA) | ~2.7x | Elevated |
| Current Equity/Total Capital | 36.6% | Below investment grade comfort |

**2023 Performance Trends:**
- Revenue increased 53.4% YoY (€33,965M vs €22,140M)
- EBITDA increased 40.3% YoY (€4,954M vs €3,529M)
- Operating cash flow strong at €4,242M
- Debt slightly decreased despite high capex (€1,687M)

## Step 4: Evaluate Hybrid Bond Appropriateness

**Arguments for Using Hybrids (Supporting Higher %:**

1. **Balance Sheet Support**: With leverage at ~2.7x, Naturgy has debt headroom and could benefit from capital optimization
2. **Investment Grade Profile**: Hybrid debt provides a cheaper alternative to equity and subordinated debt
3. **Market Conditions 2022**: Swap curve and corporate bond spreads were elevated (ISHARES 108.5 bps, SUB-SEN spreads ~230 bps), making hybrids cost-effective
4. **Operational Performance**: Strong EBITDA growth and cash generation support hybrid servicing
5. **Equity Credit Value**: At 15% cap, €4,090M in hybrid capacity represents meaningful capital optimization without exceeding limits

**Arguments Against Heavy Reliance:**

1. **Leverage Concern**: Current leverage at 2.7x is already elevated for this sector; hybrids add debt-like obligations
2. **Interest Rate Environment**: 2022 saw significant rate increases (10Y swap from 0.053% in 2021 to 1.927% in 2022), increasing servicing costs
3. **Subordinated Position**: Hybrid bonds rank below senior debt, increasing cost
4. **Financial Flexibility**: Strong cash generation provides alternative financing options
5. **Rating Stability**: Prudent use of hybrids preserves credit rating and refinancing flexibility

## Step 5: Optimal Hybrid Utilization Level

Given Naturgy's:
- Adequate but not excessive leverage (2.7x)
- Strong operational performance and cash generation
- Solid balance sheet with room for optimization
- Investment grade profile supporting hybrid issuance

**Recommendation:** Naturgy should utilize hybrids at **50%** of the S&P cap.

**Rationale:**
- 50% of €4,090M = €2,045M in hybrid capacity
- This captures meaningful capital optimization benefits without over-leveraging
- Preserves financial flexibility and credit rating
- Aligns with prudent capital structure management
- Balances cost efficiency against financial stability
- Leaves room for future hybrid issuance if credit metrics improve
