To estimate the Net Debt / EBITDA ratio for EDF for the year 2022 according to S&P methodology, we identify the necessary components from the provided data:

1.  **EBITDA**: In the provided facts, "Operating Profit Before Depreciation And Amortisation" (often used as a proxy for EBITDA) for the period 2022-01-01 to 2023-01-01 is **-4,986,000,000 EUR**.

2.  **Net Debt**: Net debt is typically calculated as total financial liabilities minus cash and cash equivalents and other liquid financial assets. 
    *   **Financial Liabilities**: This includes both current and non-current financial liabilities.
        *   Non-current financial liabilities: 71,058,000,000 EUR
        *   Current financial liabilities: 71,844,000,000 EUR
        *   Total Financial Liabilities = 142,902,000,000 EUR
    *   **Cash and Financial Assets**: This includes cash and cash equivalents and other current financial assets (as listed in the balance sheet for 2023-01-01, representing the end of 2022).
        *   Cash and cash equivalents: 10,948,000,000 EUR
        *   Other current financial assets: 58,033,000,000 EUR
        *   Total Cash and Liquid Assets = 68,981,000,000 EUR
    *   **Net Debt** = 142,902,000,000 - 68,981,000,000 = **73,921,000,000 EUR**

3.  **Ratio Calculation**:
    *   Ratio = Net Debt / EBITDA
    *   Ratio = 73,921,000,000 / -4,986,000,000
    *   Calculation: -14.8257...

When EBITDA is negative, the Net Debt/EBITDA ratio is mathematically negative and generally considered non-meaningful or "not applicable" in standard credit analysis because it does not represent a leverage coverage capability. However, requested for an estimation based on the provided figures:
