To estimate the S&P-adjusted debt-to-EBITDA ratio for Enel S.p.A. for the fiscal year ended December 31, 2022, we follow the prescribed workflow:

### 1. Industry Identification
Enel S.p.A. is an integrated global electricity and gas utility. It fits best into the "Regulated Utilities" and "Unregulated Power and Gas" categories provided in the methodologies.

### 2. Estimate Adjusted_Debt
*   **Reported Debt:**
    *   Long-term borrowings: 54,500,000,000 EUR
    *   Short-term borrowings: 13,306,000,000 EUR
    *   Current portion of long-term borrowings: 4,031,000,000 EUR
    *   Total reported debt = 71,837,000,000 EUR
*   **Eligible Cash:** 8,858,000,000 EUR
*   **Adjustments:** We consider Enel’s reported debt and subtract cash and cash equivalents (as a standard adjustment for net debt).
*   Adjusted_Debt = 71,837,000,000 - 8,858,000,000 = 62,979,000,000 EUR

### 3. Estimate Adjusted_EBITDA
We reconstruct EBITDA from the operating profit and expense data provided for 2022:
*   Profit/Loss from Operating Activities (EBIT): 11,193,000,000 EUR
*   Depreciation, Amortisation, and Impairment: 7,447,000,000 EUR
*   EBITDA = EBIT + Depreciation/Amortisation = 11,193,000,000 + 7,447,000,000 = 18,640,000,000 EUR
*   Adjustments (S&P methodologies often add back or normalize certain items; based on the data provided for 2022, we use this operating EBITDA figure): 18,640,000,000 EUR

*(Note: While S&P methodology involves further specific adjustments for leases or pension deficits, given the scope of provided data and typical utility adjustments for EBITDA, this reconstructed figure represents the core operating cash flow generated.)*

### 4. Calculate Ratio
*   Ratio = Adjusted_Debt / Adjusted_EBITDA
*   Ratio = 62,979,000,000 / 18,640,000,000 ≈ 3.3787

Rounding to two decimal places, we get 3.38.
