To estimate Moody's adjusted leverage trend for ERG S.p.A. in 2022, we analyze the key metrics influencing the Net Debt/EBITDA ratio, which is the core component of Moody's leverage assessment.

1.  **Operating Profitability (EBITDA):** The report shows the "Profit Loss From Operating Activities Before Interest Taxes Depreciation And Amortisation Expense" increased significantly from 396.68 million EUR in 2021 to 499.43 million EUR in 2022, representing a strong growth in operational cash-generating capacity.
2.  **Debt Position:** While the total "Liabilities" decreased, Moody's leverage analysis focuses on Net Debt. ERG's cash position ("Cash And Cash Equivalents") decreased from 860.35 million EUR to 392.81 million EUR. However, a significant reduction occurred in "Other Current Financial Liabilities" (from 1,342.69 million EUR to 389.72 million EUR) and "Other Noncurrent Financial Liabilities" (from 2,064.09 million EUR to 1,751.26 million EUR).
3.  **Overall Trend:** The substantial growth in EBITDA (approx. 26% increase) coupled with a significant reduction in gross financial liabilities suggests a deleveraging trend. The reduction in gross debt outweighs the reduction in cash, as evidenced by the strengthening of the equity base (Equity increased from 1,568.62 million EUR to 2,054.68 million EUR). Consequently, the leverage ratio is declining, indicating an improvement in the company's financial profile.
