Let’s go through the key elements step by step.

**1. Nature of the business**  
REDEIA CORPORACION SA (formerly Red Eléctrica Corporación) is a Spanish electricity transmission system operator and manager of critical national infrastructure. It is a regulated utility with a highly predictable revenue stream under a transparent and long-established regulatory framework. In S&P’s framework, this likely gives it a **strong regulatory advantage** and makes it eligible for low- or medial-volatility benchmarks.

**2. Financial profile and leverage**  
From the balance sheet:

- Total equity at end-2022: ~€4.89 billion  
- Noncurrent financial liabilities: ~€5.54 billion  
- Current financial liabilities: ~€1.71 billion  

We can roughly estimate **adjusted debt** as total financial liabilities excluding some non-debt items but including leases, derivatives, and provisions. The company has significant long-term borrowings (~€5.49 billion) but also has significant cash (~€795 million) and other financial assets.

Key metrics (using reported data):
- FFO (approximated as operating cash flow before working capital and interest costs) is strong — operating cash flow was ~€1.57 billion in 2022.  
- Interest costs: ~€116 million in 2022, so coverage is very high.  
- Leverage (Debt/EBITDA or FFO/Debt) appears quite moderate for a regulated network utility.  
- Dividend payout is high but covered by stable cash flows.  
- Capex in 2022: ~€536 million, which is moderate compared to operating cash flow.

**3. Refinancing and funding needs**  
The company increased cash outflows for investing activities significantly in 2022 (€1.64 billion), partly driven by acquisitions of financial instruments. Borrowing repayment was also high. However, the underlying regulated business generates strong and predictable cash flow, and the company has proven market access.

There is no indication of a transformational capex program or M&A that would require the massive balance-sheet support of 11.25%–15% hybrids. The leverage position does not appear distressed.

**4. Rating and hybrid rationale**  
REDEIA is likely rated in the “A” range by S&P (currently A- or better based on past data). For a strongly positioned regulated utility with stable cash flows, the need for hybrid instruments is low. Hybrid issuance would increase the cost of debt — the subordinated debt market yield is significantly higher than senior debt yields.

In the current interest rate environment (2022 swap rates sharply higher), the cost of hybrids would be materially above the existing cost of senior debt. The company would not gain meaningful rating uplift unless it was already near a downgrade threshold, which does not seem to be the case.

**5. Conclusion**  
Given:
- Strong regulated business profile,  
- Solid credit metrics with no immediate leverage pressure,  
- Moderate capex and refinancing needs,  
- Higher cost of hybrid vs. current debt costs,  

the rating and financial flexibility rationale for hybrid issuance is weak. The lowest category (0%) fits best — there is no compelling need and the cost would outweigh the benefits.
