To estimate the Net Debt / EBITDA ratio for VERBUND AG in 2022 based on the S&P methodology, we use the standard approach where Net Debt is calculated as Total Debt (Short-term and Long-term Financial Liabilities) minus Cash and Cash Equivalents.

1. **EBITDA:** 
Based on the provided facts for the 2022-01-01 to 2023-01-01 period, the EBITDA is explicitly reported as:
EBITDA = 3,160,679,000 EUR

2. **Total Debt:**
Total Debt consists of the company's financial liabilities at the end of the year (2023-01-01):
Current Financial Liabilities = 1,109,297,000 EUR
Noncurrent Financial Liabilities = 2,844,559,000 EUR
Total Debt = 1,109,297,000 + 2,844,559,000 = 3,953,856,000 EUR

3. **Net Debt:**
We subtract the Cash and Cash Equivalents at the end of the year (2023-01-01) from the Total Debt:
Cash and Cash Equivalents = 409,252,000 EUR
Net Debt = 3,953,856,000 - 409,252,000 = 3,544,604,000 EUR

4. **Net Debt / EBITDA Ratio:**
Ratio = Net Debt / EBITDA
Ratio = 3,544,604,000 / 3,160,679,000 ≈ 1.1215
