To estimate Moody's adjusted leverage trend for Terna S.p.A. in 2022, we need to calculate the leverage ratio for 2021 and 2022. Moody's adjusted leverage is typically defined as Adjusted Debt divided by Adjusted EBITDA (or sometimes Adjusted Capital, but Debt/EBITDA is the standard leverage metric for trend analysis in this context).

**Step 1: Calculate Adjusted EBITDA for 2021 and 2022**

EBITDA can be derived from the Profit/Loss from Operating Activities (Operating Profit) by adding back Depreciation, Amortization, and Impairment.

*   **2022:**
    *   Profit Loss From Operating Activities: 1,333,500,000 EUR
    *   Depreciation Amortisation And Impairment: 725,700,000 EUR
    *   EBITDA 2022 = 1,333,500,000 + 725,700,000 = **2,059,200,000 EUR**

*   **2021:**
    *   Profit Loss From Operating Activities: 1,200,400,000 EUR
    *   Depreciation Amortisation And Impairment: 654,400,000 EUR
    *   EBITDA 2021 = 1,200,400,000 + 654,400,000 = **1,854,800,000 EUR**

*   **Trend:** EBITDA increased from ~1.85 billion to ~2.06 billion. This is a positive factor for leverage (denominator increases).

**Step 2: Calculate Adjusted Debt for 2021 and 2022**

Adjusted Debt generally includes interest-bearing borrowings (short-term and long-term) and may include adjustments for items like hybrid bonds (often treated as equity by rating agencies if they have equity characteristics, but sometimes as debt depending on specific criteria; however, standard net debt calculations focus on financial liabilities). Let's look at the reported financial liabilities.

*   **2022 (Year End 2022-01-01 / Start 2023-01-01 balance sheet items usually represent the end of the period. The prompt labels "2023-01-01" as the end of the 2022 reporting period):**
    *   Long-term Borrowings: 8,416,700,000 EUR
    *   Short-term Borrowings: 444,100,000 EUR
    *   Current Portion of Long-term Borrowings: 1,909,300,000 EUR
    *   Current Financial Liabilities: 44,900,000 EUR
    *   Noncurrent Financial Liabilities: 247,200,000 EUR
    *   *Note on Hybrids:* The report lists "Equity Instruments Perpetual Hybrid Bonds" of 989,000,000 EUR under Equity. Rating agencies like Moody's often treat perpetual hybrids as 50% debt and 50% equity, or fully equity if strong. However, even if we just look at core financial debt:
    *   Total Financial Debt 2022 ≈ 8,416.7 + 444.1 + 1,909.3 + 44.9 + 247.2 = **11,062,200,000 EUR**
    *   Less Cash and Cash Equivalents (2,155,100,000 EUR) -> Net Debt ≈ 8,907,100,000 EUR.

*   **2021 (Year End 2021-01-01 / Start 2022-01-01 balance sheet items):**
    *   Long-term Borrowings: 8,835,000,000 EUR
    *   Short-term Borrowings: 1,947,000,000 EUR
    *   Current Portion of Long-term Borrowings: 1,640,000,000 EUR
    *   Current Financial Liabilities: 45,800,000 EUR
    *   Noncurrent Financial Liabilities: 83,700,000 EUR
    *   Total Financial Debt 2021 ≈ 8,835.0 + 1,947.0 + 1,640.0 + 45.8 + 83.7 = **12,551,500,000 EUR**
    *   Less Cash and Cash Equivalents (1,566,800,000 EUR) -> Net Debt ≈ 10,984,700,000 EUR.

*   **Trend in Debt:**
    *   Gross Financial Debt decreased from ~12.55 billion to ~11.06 billion.
    *   Net Debt decreased from ~10.98 billion to ~8.91 billion.
    *   This is a significant reduction in the numerator.

**Step 3: Calculate Leverage Ratio Trend**

*   **2021 Leverage (Net Debt / EBITDA):**
    *   10,984,700,000 / 1,854,800,000 ≈ **5.92x**

*   **2022 Leverage (Net Debt / EBITDA):**
    *   8,907,100,000 / 2,059,200,000 ≈ **4.33x**

Even if we use Gross Debt:
*   2021: 12,551.5 / 1,854.8 ≈ 6.77x
*   2022: 11,062.2 / 2,059.2 ≈ 5.37x

In both cases, the leverage ratio has decreased significantly. A decrease in the leverage ratio indicates an **Improving** credit profile regarding leverage. The company reduced its debt burden while increasing its operating earnings.
