I'll work through this step-by-step for HERA S.P.A.

## Step 1: Identify the Relevant Industry

HERA S.P.A. is an Italian multi-utility company (Gruppo Hera) operating in energy, water, and waste management. It falls under the **Regulated Utilities** sector (multi-utilities subsector), though it also has unregulated activities. I'll apply the regulated utilities methodology as the primary framework.

## Step 2: Estimate Adjusted EBITDA

**Reconstructing EBITDA from the income statement:**

EBITDA = Profit from Operating Activities + Amortisation, Depreciation and Provisions
EBITDA = 533,800,000 + 667,100,000 = 1,200,900,000 EUR

**Lease adjustments:**
S&P adds back lease depreciation and treats leases as debt. The right-of-use asset depreciation is already included in D&A. Under S&P methodology, we need to add back the lease-related depreciation (already in EBITDA since we added back all D&A) and the lease interest. The lease payments from financing activities are 43,400,000 EUR. The lease interest component would be embedded in finance costs. For S&P purposes, we reclassify operating lease payments as a financing item - the EBITDA already includes lease-related D&A so the main adjustment is recognizing lease interest is already excluded from operating profit.

Lease liabilities: Current 21,300,000 + Noncurrent 55,100,000 = 76,400,000 EUR
Estimated lease interest ≈ ~3,500,000 (roughly 4-5% on average lease liability)

Adjusted EBITDA ≈ 1,200,900,000 + 3,500,000 ≈ 1,204,400,000 EUR

**Pension adjustments:**
Pension deficit (noncurrent employee benefits): 92,000,000 EUR. The service cost adjustments are minor and already in operating costs.

Adjusted_EBITDA ≈ 1,204,400,000 EUR

## Step 3: Estimate FFO

**Cash interest:**
Finance costs paid = 128,000,000 EUR
Finance income received = 41,800,000 EUR (but S&P typically uses gross interest paid)
Add lease interest: ~3,500,000

Cash interest (S&P) = 128,000,000 + 3,500,000 = 131,500,000 EUR

**Cash taxes:**
Income taxes paid = 165,900,000 EUR

FFO = Adjusted_EBITDA - cash_interest - cash_taxes
FFO = 1,204,400,000 - 131,500,000 - 165,900,000 = 907,000,000 EUR

## Step 4: Estimate Adjusted Debt

**Reported debt:**
- Noncurrent financial liabilities: 5,689,900,000
- Current financial liabilities: 650,100,000
Total reported debt = 6,340,000,000 EUR

**Lease liabilities:**
- Noncurrent: 55,100,000
- Current: 21,300,000
Total leases = 76,400,000 EUR

**Pension deficit:**
Noncurrent provisions for employee benefits: 92,000,000 EUR

**Surplus cash deduction:**
S&P typically allows deduction of some cash. For utilities, a portion of cash may be considered operational. Total cash = 1,942,400,000 EUR. However, given the large working capital swings and the significant increase in cash (much from new borrowings), S&P might not net all cash. I'll conservatively deduct minimal surplus cash. For a utility of this size, operational cash needs might be ~2-3% of revenue ≈ ~400-600M. Given the extraordinary cash position likely tied to pre-funding, I'll assume eligible surplus cash deduction of approximately 0 (conservative for utilities with large borrowing programs).

Adjusted_Debt = 6,340,000,000 + 76,400,000 + 92,000,000 = 6,508,400,000 EUR

## Step 5: Calculate FFO / Adjusted Debt

FFO / Adjusted_Debt = 907,000,000 / 6,508,400,000 = 0.13935

Rounding to four decimal places: 0.1394
