To estimate the Moody’s adjusted leverage trend for Red Eléctrica Corporación, S.A. (Redeia) for 2022, we analyze the key metrics influencing its financial risk profile:

1.  **Debt Reduction:** According to the provided data, "Longterm Borrowings" decreased from 5,896,170,000 EUR in 2022-01-01 to 5,491,124,000 EUR in 2023-01-01. Simultaneously, "Current Borrowings And Current Portion Of Noncurrent Borrowings" decreased significantly from 1,391,722,000 EUR to 721,845,000 EUR. This represents a substantial reduction in gross debt.
2.  **Equity Strengthening:** "Equity Attributable To Owners Of Parent" increased from 3,631,082,000 EUR (2022-01-01) to 4,789,535,000 EUR (2023-01-01), strengthening the company's capital base.
3.  **Profitability and Cash Flow:** The company maintained robust operating profit (Profit Loss From Operating Activities was 961,554,000 EUR) and strong cash flows from operations (1,566,829,000 EUR). The reduction in interest-bearing debt relative to the stable performance indicates a focus on deleveraging.
4.  **Leverage Ratio:** With a significant decrease in total borrowings combined with an increase in total equity, the leverage ratio (Net Debt / EBITDA or Debt / Capitalization) shows a downward trend, which indicates a strengthening of the credit profile.

Given the significant reduction in total debt and the strengthening of the equity base, Moody’s adjusted leverage for Redeia is considered to be improving.
