S&P’s adjusted Net Debt / EBITDA generally uses adjusted debt net of readily available cash, divided by EBITDA. With the facts provided, we can approximate it using balance-sheet financial liabilities less cash, and EBITDA as “Operating Profit Before Depreciation and Amortisation” (EDF’s EBE/EBITDA proxy).

For 2022 year-end:

- Other noncurrent financial liabilities: €71.058bn
- Other current financial liabilities: €71.844bn
- Gross financial debt approximation:  
  €71.058bn + €71.844bn = €142.902bn
- Cash and cash equivalents: €10.948bn
- Net debt approximation:  
  €142.902bn − €10.948bn = €131.954bn

EBITDA / EBE for 2022:

- Operating Profit Before Depreciation and Amortisation: −€4.986bn

Net Debt / EBITDA:

- €131.954bn / −€4.986bn = −26.47x

Because EBITDA is negative, the ratio is not economically meaningful in the usual leverage sense; mechanically, it is approximately −26.5x.
