To estimate Moody's adjusted leverage trend for 2022, we must analyze the changes in the company's debt and earnings capacity over the year. 

1. **Debt Evolution**: We look at the reported financial debt, which consists of non-current and current financial liabilities. 
- At the end of 2021 (beginning of 2022), total reported financial debt was: 
  Non-current financial liabilities (2,064,088,000) + Current financial liabilities (1,342,688,000) = 3,406,776,000 EUR.
- At the end of 2022 (beginning of 2023), total reported financial debt was: 
  Non-current financial liabilities (1,751,255,000) + Current financial liabilities (389,716,000) = 2,140,971,000 EUR.
This represents a massive reduction of over 1.2 billion EUR in gross debt during the period.

2. **Earnings Capacity**: Moody's typically evaluates earnings using metrics like EBITDA. 
- The reported EBITDA (Profit Loss From Operating Activities Before Interest Taxes Depreciation And Amortisation Expense) increased significantly from 396,680,000 EUR in 2021 to 499,430,000 EUR in 2022. 
- Furthermore, the Profit From Discontinued Operations also surged from 88,488,000 EUR to 294,131,000 EUR, indicating even stronger total cash generation capacity for the group during the year.

3. **Leverage Dynamics**: With gross debt decreasing by approximately 37% and EBITDA growing by approximately 26%, the leverage ratio (Debt/EBITDA) falls dramatically. 

Because both the numerator (debt) dropped sharply and the denominator (earnings) increased, the adjusted leverage position for ERG S.p.A. in 2022 is clearly improving.
