To estimate Moody's adjusted leverage trend for TenneT Holding B.V. in 2022, we analyze the company's EBITDA and debt levels over the period. Moody's adjusted leverage primarily looks at metrics such as Gross Debt to EBITDA or Funds from Operations (FFO) to Debt.

1. **EBITDA Estimate:**
A straightforward proxy for EBITDA is to add back "Depreciation And Amortisation Expense" to "Profit Loss From Operating Activities".
- **2021:** Operating Profit (-€275 million) + D&A (€1,165 million) = **€890 million**
- **2022:** Operating Profit (-€976 million) + D&A (€1,233 million) = **€257 million**
EBITDA severely contracted from 2021 to 2022.

2. **Total Debt Estimate:**
We can sum "Long-term Borrowings", "Short-term Borrowings", and "Lease Liabilities" (both current and non-current).
- **2021 (As of 2022-01-01):** €12,366m (Long-term) + €1,339m (Short-term) + €235m (Non-current Lease) + €169m (Current Lease) = **€14,109 million**
- **2022 (As of 2023-01-01):** €19,006m (Long-term) + €709m (Short-term) + €574m (Non-current Lease) + €155m (Current Lease) = **€20,444 million**

3. **Leverage Profile:**
With Total Debt increasing substantially from ~€14.1 billion to ~€20.4 billion, and EBITDA shrinking from €890 million to €257 million, the Gross Debt to EBITDA ratio spiked significantly (from approximately 15.8x in 2021 to almost 79.5x in 2022). Additionally, operating cash flow sharply declined from ~€5.7 billion in 2021 to ~€1.2 billion in 2022, which further weakens typical cash flow-based leverage parameters (like CFO/Debt).

Since the debt burdens grew considerably while underlying earnings and operating cash flows declined, the leverage position has materially worsened.
