We start by calculating net debt. Total financial liabilities (including short‑ and long‑term borrowings, lease obligations and other financial liabilities) for 2022 are:

- Non‑current financial liabilities at fair value: 44,763,000 EUR  
- Other non‑current financial liabilities: 2,064,088,000 EUR  
- Non‑current lease liabilities: 122,663,000 EUR  
- Current financial liabilities at fair value: 170,857,000 EUR  
- Other current financial liabilities: 1,342,688,000 EUR  
- Current lease liabilities: 6,282,000 EUR  

Sum ≈ 3,751,341,000 EUR.  

Cash and cash equivalents at the end of 2022 are 860,352,000 EUR.  

Net debt = 3,751,341,000 – 860,352,000 ≈ 2,890,989,000 EUR.

For FFO, S&P defines funds from operations as cash generated from operations before changes in working capital (i.e., the “Cash flows from used in operations before changes in working capital” line). In 2022 this amount is 616,360,000 EUR.

The FFO/Net‑debt ratio is therefore:

FFO / Net debt ≈ 616,360,000 / 2,890,989,000 ≈ 0.213.
