Let’s go step-by-step.

First, we need **Net Debt / EBITDA** for both 2021 and 2022.

### 1. EBITDA for 2022 & 2021
EBITDA here is **“Operating Profit Before Depreciation And Amortisation”**:
- 2022: -4,986,000,000 EUR
- 2021: 18,005,000,000 EUR

---

### 2. Net Debt  
No direct “Net Debt” line; we must estimate it as:  
**Net Debt = Borrowings – Cash & Cash Equivalents**

From the balance sheet:  
- **Borrowings** = “Other Noncurrent Financial Liabilities” + “Other Current Financial Liabilities”  

2022:
- Noncurrent: 71,058,000,000
- Current: 71,844,000,000
- Total Borrowings: 142,902,000,000

2021:
- Noncurrent: 56,543,000,000
- Current: 45,014,000,000
- Total Borrowings: 101,557,000,000

**Cash and cash equivalents**:  
- 2022: 10,948,000,000  
- 2021: 9,919,000,000  

**Net Debt**:  
- 2022: 142,902,000,000 – 10,948,000,000 = 131,954,000,000  
- 2021: 101,557,000,000 – 9,919,000,000 = 91,638,000,000  

---

### 3. Net Debt / EBITDA
- 2022: 131,954 / -4,986 = **-26.47x**  
- 2021: 91,638 / 18,005 = **5.09x**  

---

### 4. Year-on-year change
- Difference = (-26.47) – 5.09 = **-31.56x**  
This is a massive deterioration, far beyond the ±0.3x threshold.
