To estimate Moody's adjusted leverage trend for VERBUND AG in 2022, we need to compare the leverage ratio at the beginning of 2022 (end of 2021) with the leverage ratio at the end of 2022. 

Moody's adjusted leverage is typically defined as Adjusted Debt / Adjusted Debt + Equity. While Moody's makes various standard adjustments (such as capitalizing operating leases, adding unconsolidated debt, etc.), we can assess the trend using the reported figures provided for Debt and Equity, assuming standard adjustments affect the figures proportionally or remain relatively stable in their impact on the ratio.

**1. End of 2021 (Beginning of 2022) Leverage:**
- Noncurrent Financial Liabilities (2021-12-31): 1,202,154,000 EUR
- Current Financial Liabilities (2021-12-31): 84,056,000 EUR
- Total Reported Debt = 1,202,154,000 + 84,056,000 = 1,286,210,000 EUR
- Total Equity (2021-12-31): 6,807,399,000 EUR
- Leverage Ratio (2021) = 1,286,210,000 / (1,286,210,000 + 6,807,399,000) ≈ 15.9%

**2. End of 2022 Leverage:**
- Noncurrent Financial Liabilities (2022-12-31): 1,834,155,000 EUR
- Current Financial Liabilities (2022-12-31): 1,462,453,000 EUR
- Total Reported Debt = 1,834,155,000 + 1,462,453,000 = 3,296,608,000 EUR
- Total Equity (2022-12-31): 6,362,949,000 EUR
- Leverage Ratio (2022) = 3,296,608,000 / (3,296,608,000 + 6,362,949,000) ≈ 34.1%

**Conclusion:**
Comparing the leverage ratios, there is a significant increase from approximately 15.9% at the end of 2021 to 34.1% at the end of 2022. The leverage has more than doubled, driven by a substantial increase in total debt (especially current financial liabilities which surged by over 1.3 billion EUR) while equity slightly decreased. Therefore, the adjusted leverage trend for 2022 is deteriorating.
