To estimate Moody’s adjusted leverage trend for VERBUND AG in 2022, we need to analyze the change in the ratio of Adjusted Debt to Adjusted EBITDA (or a similar leverage metric) from the end of 2021 to the end of 2022.

**1. Identify Key Financial Metrics:**

*   **EBITDA:**
    *   2021 (Jan 1 - Jan 1): 1,578,959,000 EUR
    *   2022 (Jan 1 - Jan 1): 3,160,679,000 EUR
    *   *Observation:* EBITDA more than doubled, increasing by approximately 100%. This is a significant positive driver for leverage improvement.

*   **Debt (Financial Liabilities):**
    Moody's typically considers "Total Debt" as the sum of Current and Non-current Financial Liabilities. Sometimes lease liabilities are included, but let's look at the core financial liabilities first.
    *   **Non-current Financial Liabilities:**
        *   2021-01-01: 1,202,154,000 EUR
        *   2022-01-01: 1,834,155,000 EUR
        *   2023-01-01: 2,844,559,000 EUR
    *   **Current Financial Liabilities:**
        *   2021-01-01: 84,056,000 EUR
        *   2022-01-01: 1,462,453,000 EUR
        *   2023-01-01: 1,109,297,000 EUR

    *   **Total Financial Liabilities (Debt Proxy):**
        *   End of 2021 (2022-01-01 balance sheet represents the state at the end of the 2021 fiscal year? No, the labels are "2022-01-01" which is the start of the 2022 period, i.e., end of 2021. Let's verify standard reporting. Usually, "2022-01-01" in these datasets refers to the balance sheet date. Let's assume the balance sheet dates are Dec 31 of the prior year or Jan 1 of the current year.
        *   Debt at End of 2021 (labeled 2022-01-01): $1,834,155,000 + 1,462,453,000 = 3,296,608,000$ EUR.
        *   Debt at End of 2022 (labeled 2023-01-01): $2,844,559,000 + 1,109,297,000 = 3,953,856,000$ EUR.

    *   *Wait, let's look at the flow.* The question asks for the trend *for* 2022. This usually implies comparing the leverage ratio at the end of 2021 vs the end of 2022.
    *   **Leverage Ratio Calculation (Debt / EBITDA):**
        *   **2021 Leverage:**
            *   Debt (End 2021 / Start 2022): ~3,297 million EUR
            *   EBITDA (2021 Full Year): ~1,579 million EUR
            *   Ratio: $3,297 / 1,579 \approx 2.09x$
        *   **2022 Leverage:**
            *   Debt (End 2022 / Start 2023): ~3,954 million EUR
            *   EBITDA (2022 Full Year): ~3,161 million EUR
            *   Ratio: $3,954 / 3,161 \approx 1.25x$

**2. Analysis of Trend:**

*   The leverage ratio decreased significantly from approximately **2.09x** in 2021 to **1.25x** in 2022.
*   Although total debt increased (from ~3.3bn to ~3.95bn), the EBITDA increased much more dramatically (from ~1.58bn to ~3.16bn).
*   A decrease in the Debt/EBITDA ratio indicates that the company is generating enough earnings to cover its debt obligations more comfortably, or that equity is growing faster than debt relative to earnings power.
*   In credit rating terminology, a lower leverage ratio is considered **Improving**.

**3. Consideration of "Adjusted" Leverage:**
Moody's adjustments often include adding back lease liabilities or subtracting cash.
*   **Cash:** Cash increased from 318m to 409m. Net Debt would be lower, but the trend in Net Debt/EBITDA would also show improvement because the denominator (EBITDA) doubled while the numerator (Net Debt) increased by only ~20%.
*   **Leases:** Lease liabilities are relatively small compared to the magnitude of EBITDA growth.
*   **Derivatives:** VERBUND has significant derivative positions. Moody's might adjust for these, but the core operational leverage (Debt/EBITDA) is the primary driver. The massive increase in EBITDA driven by higher electricity prices and sales volume overwhelmingly improves the coverage ratios.

**Conclusion:**
The substantial increase in EBITDA outpaced the increase in debt, leading to a significant reduction in the leverage ratio. Therefore, the leverage trend is improving.
