To estimate **Net Debt / EBITDA** for 2022 using an S&P-style approach:

1. **Debt**
   - Short-term borrowings: €4,446m
   - Current portion of long-term borrowings: €3,097m
   - Current lease liabilities: €884m
   - Long-term borrowings: €19,374m
   - Noncurrent lease liabilities: €4,067m

   Total debt including lease liabilities:
   \[
   4{,}446 + 3{,}097 + 884 + 19{,}374 + 4{,}067 = 31{,}868 \text{ million}
   \]

2. **Cash and cash equivalents**
   - Cash and cash equivalents: €10,155m

   Net debt:
   \[
   31{,}868 - 10{,}155 = 21{,}713 \text{ million}
   \]

3. **EBITDA**
   - Profit/loss from operating activities: €17,510m
   - Depreciation and amortisation: €7,205m
   - Impairment loss/reversal: €1,140m
   - Write-off of tangible and intangible assets: €599m

   EBITDA estimate:
   \[
   17{,}510 + 7{,}205 + 1{,}140 + 599 = 26{,}454 \text{ million}
   \]

4. **Net Debt / EBITDA**
   \[
   \frac{21{,}713}{26{,}454} \approx 0.82
   \]
