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

## Step 1: Identify the Relevant Industry

ACEA S.P.A. is an Italian multi-utility company operating in water, electricity distribution, and energy services. It falls under the **Regulated Utilities** industry methodology. ACEA has both regulated (water, electricity distribution/networks) and some unregulated activities (energy supply/generation).

## Step 2: Estimate Adjusted EBITDA

First, let me reconstruct EBITDA from the reported figures.

**Reported EBITDA (Gross Profit / Margine Operativo Lordo):**
The "Gross Profit" line item appears to represent EBITDA in Italian utility reporting (Margine Operativo Lordo = EBITDA):
- EBITDA 2022 = 1,305,021,000 EUR

This is confirmed by:
- Revenue (5,138,245) - Operating Expense (3,861,121) + Other income from subsidiaries/JVs (27,897) = 1,305,021 ✓

**S&P Adjustments:**

**Lease adjustment:** Right-of-use assets are reported at 90,397,000 (2022 year-end) vs 53,096,000 (2021 year-end). Under S&P methodology, operating lease payments are added back to EBITDA and the depreciation of ROU assets is already included. The lease adjustment for EBITDA involves adding back the lease interest component. I'll estimate the lease depreciation from the ROU asset changes and new leases. Given the ROU assets of ~90M, I'll estimate annual lease payments around 25-30M. The interest portion would be roughly 3-4M. For simplicity, I'll estimate a lease EBITDA add-back of approximately 4,000,000 EUR (interest on lease liabilities).

However, since IFRS 16 is already applied and EBITDA already excludes lease depreciation, the S&P adjustment adds back the full lease payment and removes the IFRS 16 treatment. The net effect on EBITDA is typically the lease interest portion. I'll estimate ~4M.

**Pension adjustment:** Employee benefit obligations (non-current) = 112,989,000. The actuarial gains recorded in OCI = 6,409,000 (pre-tax). S&P typically adjusts for service cost vs. cash contributions. The net change in employee benefits was -19,158,000 (a decrease). This suggests cash payments exceeded the P&L charge. I'll make a modest adjustment here of approximately 0 for simplicity as the impact is relatively small.

**Adjusted EBITDA ≈ 1,305,021,000 + 4,000,000 ≈ 1,309,021,000 EUR**

## Step 3: Estimate FFO

**Cash Interest:**
- Interest paid (from cash flow statement) = 114,121,000 EUR
- Add lease interest portion: ~4,000,000
- Total cash interest ≈ 118,121,000 EUR

**Cash Taxes:**
- Income taxes paid = 178,506,000 EUR

**FFO = Adjusted_EBITDA - cash_interest - cash_taxes**
FFO = 1,309,021,000 - 118,121,000 - 178,506,000 = 1,012,394,000 EUR

## Step 4: Estimate Adjusted Debt

**Reported Financial Debt:**
- Non-current financial liabilities = 4,722,263,000
- Current financial liabilities = 619,418,000
- Total reported debt = 5,341,681,000

**Lease liabilities (already in reported debt under IFRS 16):** The ROU assets of 90,397,000 suggest lease liabilities of similar magnitude. These are likely already included in the financial liabilities above. S&P would ensure these are captured — I'll assume they are.

**Pension deficit:** Non-current employee benefits = 112,989,000

**Cash deduction:** Cash and equivalents = 559,908,000. S&P typically allows limited cash netting. For utilities, I'll assume ~75% is eligible: ~420,000,000.

**Adjusted_Debt = 5,341,681,000 + 112,989,000 - 420,000,000 = 5,034,670,000 EUR**

## Step 5: Calculate FFO / Adjusted_Debt

FFO / Adjusted_Debt = 1,012,394,000 / 5,034,670,000 = 0.2011
