To estimate Moody’s adjusted leverage trend for ERG S.p.A. in 2022, we need to analyze the change in the ratio of Adjusted Debt to Adjusted EBITDA (or a similar proxy for operating cash flow generation) between 2021 and 2022. Moody's typically adjusts reported debt to include items like lease liabilities and potentially pension deficits, and adjusts EBITDA for non-recurring items, though we will use the provided reported figures as a strong proxy given the lack of specific adjustment details.

**Step 1: Calculate Adjusted Debt (Proxy)**
Moody's usually includes interest-bearing debt and lease liabilities.
*   **2021 Debt Components:**
    *   Other Noncurrent Financial Liabilities: 2,064,088,000 EUR
    *   Noncurrent Lease Liabilities: 122,663,000 EUR
    *   Other Current Financial Liabilities: 1,342,688,000 EUR
    *   Current Lease Liabilities: 6,282,000 EUR
    *   Current Financial Liabilities at FVTPL: 170,857,000 EUR
    *   Noncurrent Financial Liabilities at FVTPL: 44,763,000 EUR
    *   *Total Reported Interest-Bearing Debt (approx):* ~3,751 million EUR.

*   **2022 Debt Components:**
    *   Other Noncurrent Financial Liabilities: 1,751,255,000 EUR
    *   Noncurrent Lease Liabilities: 150,955,000 EUR
    *   Other Current Financial Liabilities: 389,716,000 EUR
    *   Current Lease Liabilities: 6,362,000 EUR
    *   Current Financial Liabilities at FVTPL: 76,644,000 EUR
    *   Noncurrent Financial Liabilities at FVTPL: 0 EUR
    *   *Total Reported Interest-Bearing Debt (approx):* ~2,375 million EUR.

There is a significant **decrease** in total financial liabilities from ~3,751 million EUR in 2021 to ~2,375 million EUR in 2022. This is largely driven by a massive reduction in "Other Current Financial Liabilities" (from 1,342M to 389M) and "Other Noncurrent Financial Liabilities" (from 2,064M to 1,751M). The cash flow statement confirms large repayments of borrowings and a net cash outflow from financing activities of -1,695 billion EUR, indicating substantial deleveraging.

**Step 2: Calculate Adjusted EBITDA (Proxy)**
We use "Profit Loss From Operating Activities Before Interest Taxes Depreciation And Amortisation Expense" (EBITDA).
*   **2021 EBITDA:** 396,680,000 EUR
*   **2022 EBITDA:** 499,430,000 EUR

EBITDA **increased** by approximately 26% from 2021 to 2022.

**Step 3: Analyze Leverage Ratio Trend**
*   **2021 Leverage (Debt/EBITDA):** ~3,751 / 396.7 ≈ 9.45x
*   **2022 Leverage (Debt/EBITDA):** ~2,375 / 499.4 ≈ 4.75x

The leverage ratio has decreased significantly (from ~9.5x to ~4.8x). A lower leverage ratio indicates that the company has less debt relative to its earnings power. This is a positive credit development.

**Conclusion:**
The combination of a substantial reduction in net debt (due to repayments and asset disposals, evidenced by the cash flow from losing control of subsidiaries) and an increase in operating profitability (EBITDA) leads to a sharp improvement in the leverage metric. Therefore, the trend is improving.
