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. Looking at the provided methodologies:
- "Multi-utilities" is listed under **Regulated Utilities** (CPGP: National industry and utilities)
- ACEA operates in water, electricity, and gas distribution - classic regulated utility activities

The company fits the **Regulated Utilities** sector.

## Step 2: Estimate Adjusted_Debt

For Regulated Utilities, I need to follow S&P guidelines. Let me identify the components from the balance sheet data (2023-01-01 for year-end 2022):

**Reported Debt Components:**
- "Other Noncurrent Financial Liabilities" (2023-01-01): 4,722,263,000 EUR
- "Other Current Financial Liabilities" (2023-01-01): 619,418,000 EUR

Total reported debt = 4,722,263,000 + 619,418,000 = **5,341,681,000 EUR**

**Leases (Right-of-use assets indicate lease liabilities):**
- "Rightofuse Assets" (2023-01-01): 90,397,000 EUR
- Under IFRS 16, right-of-use assets equal lease liabilities, so lease liabilities = **90,397,000 EUR**

**Pension Deficit:**
- "Noncurrent Provisions For Employee Benefits" (2023-01-01): 112,989,000 EUR
- This represents pension/employee benefit obligations. Need to check if there's a deficit.
- Looking at equity: "Reserve Of Remeasurements Of Defined Benefit Plans Member" is negative (-14,329,000 at 2023-01-01, -18,234,000 at 2022-01-01), indicating some deficit.
- However, the provision itself is the liability. For S&P purposes, we typically look at underfunded status. Without plan assets disclosed, I'll use the provision as a proxy, but this is already in "Noncurrent Provisions" not in debt. The S&P approach for pensions is to add the deficit (liability minus plan assets). Since we don't have plan assets, I'll be conservative and note that defined benefit obligations are often already captured. Given the methodology mentions "pension_deficit", I'll check if there's a clear deficit.

Actually, looking more carefully: "Noncurrent Provisions For Employee Benefits" of 112,989,000 likely includes pension obligations. Without separate plan asset data, and given this is a provision not financial liability, I'll include this as pension-related debt-like item if underfunded. But we lack data on plan assets. I'll be conservative and include a portion or note uncertainty. For regulated utilities, pension deficits are typically added.

Let me re-examine: The "Noncurrent Provisions For Employee Benefits" is 112,989,000. The negative reserve in equity suggests some remeasurement losses. I'll include **50,000,000 EUR** as estimated pension deficit (conservative estimate given the remeasurement reserve is relatively small compared to the provision).

Actually, for S&P methodology, the typical approach is: if the pension is underfunded (liabilities > assets), add the deficit. Without plan assets, I'll use the remeasurement reserve as indicator but not add full provision. Let me use **0** for pension deficit as a conservative approach since we can't determine underfunding clearly, or use the provision as proxy.

Let me reconsider: In many European utilities, pension obligations are often unfunded or partially funded. I'll add the full "Noncurrent Provisions For Employee Benefits" as debt-like: **112,989,000 EUR**

**Hybrid Debt:** Not identified in the data. **0**

**Other Debt-like Items:**
- "Noncurrent Provisions" total: 218,025,000 (includes employee benefits 112,989,000 + other provisions)
- The other portion: 218,025,000 - 112,989,000 = 105,036,000. These are likely regulatory/operating provisions, not debt-like.

**Guarantees:** Not explicitly identified. **0**

**Eligible Cash:**
- "Disponibilità Liquide E Mezzi Equivalenti Alla Fine Dellesercizio Continued Operations" (2023-01-01): 559,908,000 EUR
- "Disponibilità Liquide E Mezzi Equivalenti Alla Fine Dellesercizio Discontinued Operations" (2023-01-01): 0 EUR
- Total cash = **559,908,000 EUR**

However, for regulated utilities, S&P may not fully deduct cash if it's needed for operations. But standard approach is to deduct available cash.

Let me also check "Current Assets Other Than Assets Or Disposal Groups Classified As Held For Sale Or As Held For Distribution To Owners" = 19,076,000 - this seems to be held for sale, not relevant.

**Adjusted Debt calculation:**
- Reported debt: 5,341,681,000
- Leases: 90,397,000
- Pension deficit (provisions for employee benefits): 112,989,000
- Other debt-like: 0
- Less: Eligible cash: (559,908,000)

Adjusted_Debt = 5,341,681,000 + 90,397,000 + 112,989,000 - 559,908,000 = **4,985,159,000 EUR**

Wait - let me reconsider the cash. For regulated utilities with seasonal working capital needs, S&P may make specific adjustments. But without specific seasonal distortion, I'll use standard approach.

Actually, re-reading: the methodology mentions "Where substantial seasonal working capital requirements...distort leverage measures, we adjust inventory and debt balances by netting the value of inventory against outstanding short-term borrowings." This doesn't seem to apply here.

Let me recalculate more carefully:
- Noncurrent financial liabilities: 4,722,263,000
- Current financial liabilities: 619,418,000
- Total debt: 5,341,681,000

Adding leases (already in debt under IFRS 16? Actually under IFRS 16, lease liabilities ARE included in financial liabilities. So the 90,397,000 right-of-use asset likely corresponds to lease liabilities already in the 5,341,681,000. Let me check if we can identify this.

Looking at "Other Noncurrent Financial Liabilities" and "Other Current Financial Liabilities" - these likely include lease liabilities under IFRS 16. So I should NOT double count. Let me assume leases are already included in reported debt.

Revised Adjusted_Debt:
- Reported debt: 5,341,681,000 (includes leases under IFRS 16)
- Pension deficit: 112,989,000
- Less cash: (559,908,000)

Adjusted_Debt = 5,341,681,000 + 112,989,000 - 559,908,000 = **4,894,762,000 EUR**

Or if we want to be more conservative and not assume leases are included:
Actually, IFRS 16 requires lease liabilities to be in financial liabilities. So yes, included.

But wait - let me check if there are specific lease liabilities we can identify. The "Rightofuse Assets" is 90,397,000. Under IFRS 16, lease liabilities should approximately equal right-of-use assets at inception, but may differ due to timing. Let me assume lease liabilities ≈ 90,397,000 and already included.

However, for S&P purposes, they sometimes add back operating leases if not already in debt (pre-IFRS 16). Under IFRS 16, this is already done.

Let me use: Adjusted_Debt = 5,341,681,000 + 112,989,000 - 559,908,000 = **4,894,762,000 EUR**

Actually, I want to double-check: should I include all "Noncurrent Provisions For Employee Benefits" or just the deficit? S&P says "pension_deficit". The provision is 112,989,000. If this is the net liability (after plan assets), then it's the deficit. I'll use it.

## Step 3: Estimate Adjusted_EBITDA

For Regulated Utilities, I need to reconstruct EBITDA or use reported figures.

From the income statement (2022-01-01 to 2023-01-01):
- "Profit Loss From Operating Activities" (EBIT): 565,851,000 EUR
- "Adjustments For Depreciation And Amortisation Expense": 594,636,000 EUR
- "Adjustments For Impairment Loss Reversal Of Impairment Loss Recognised In Profit Or Loss": 67,680,000 EUR

EBITDA = EBIT + Depreciation & Amortization + Impairment (if below EBITDA line)

Wait - the "Adjustments For Depreciation And Amortisation Expense" in cash flow is 594,636,000. The income statement has "Ammortamenti E Accantonamenti" of 625,799,000. Let me use the cash flow adjustment as it's cleaner for D&A.

Actually, "Ammortamenti E Accantonamenti" (625,799,000) likely includes depreciation, amortization, and other provisions/accruals. The cash flow "Adjustments For Depreciation And Amortisation Expense" (594,636,000) is more clearly D&A.

EBITDA = EBIT + D&A = 565,851,000 + 594,636,000 = **1,160,487,000 EUR**

Or using the income statement approach:
- "Gross Profit": 1,305,021,000
- Less: "Impairment Loss...": (113,370,000)
- Less: "Ammortamenti E Accantonamenti": (625,799,000)
- = Operating profit: 565,852,000 (matches 565,851,000)

So EBITDA = 1,305,021,000 - 113,370,000 = 1,191,651,000? No wait, impairment is also below gross profit.

Actually: Gross Profit 1,305,021,000 - Impairment 113,370,000 - D&A 625,799,000 = 565,852,000 EBIT

So EBITDA = EBIT + D&A + Impairment (if impairment is operating) = 565,852,000 + 625,799,000 + 113,370,000 = 1,305,021,000 = Gross Profit!

Yes! EBITDA = Gross Profit for this company (since gross profit already excludes external costs and employee benefits, and impairment/D&A are below). Actually, let me verify:

Gross Profit = Revenue - Operating Expenses (external costs + employee benefits)? 
Revenue: 5,138,245,000
Operating Expense: 3,861,121,000
Gross Profit: 1,305,021,000? But 5,138,245,000 - 3,861,121,000 = 1,277,124,000, not 1,305,021,000.

Wait, let me check: Revenue includes "Ricavi Da Vendita E Prestazioni" (4,957,179,000) + "Other Income" (181,066,000) = 5,138,245,000.

Operating Expense = "Employee Benefits Expense" (305,066,000) + "Costi Esterni" (3,556,055,000) = 3,861,121,000.

But 5,138,245,000 - 3,861,121,000 = 1,277,124,000, not 1,305,021,000.

Hmm, there's a discrepancy. Let me check: "Gross Profit" is reported as 1,305,021,000. Maybe there's other income/expense included. Actually, "Other Income" of 181,066,000 might not be fully in revenue, or there are other items.

Actually, looking at Italian GAAP/IFRS format: "Ricavi Da Vendita E Prestazioni" is revenues from sales and services. "Other Income" might include other operating income. The "Gross Profit" (Margine Operativo Lordo) in Italian terminology is actually more like operating profit before D&A - it's EBITDA!

Yes! In Italian financial reporting, "Margine Operativo Lordo" (Gross Operating Margin) is typically EBITDA. Let me verify:
- "Margine Operativo Lordo Di Cui Verso Parti Correlate" = 82,855,000
- "Gross Profit" = 1,305,021,000

So "Gross Profit" here = EBITDA = **1,305,021,000 EUR**

Let me verify with EBIT + D&A:
- EBIT: 565,851,000
- D&A (from cash flow): 594,636,000
- EBITDA: 1,160,487,000

This doesn't match 1,305,021,000. So "Gross Profit" is NOT EBITDA in the S&P/IFRS sense.

Let me recalculate: The 1,305,021,000 might include other items. Let me trace through:
- Revenue: 5,138,245,000
- Cost of sales would be: ?

Actually, looking more carefully at Italian terminology: "Margine Operativo Lordo" (MOL) is typically Revenues - Variable Costs - External Costs, or roughly EBITDA. But here "Gross Profit" is 1,305,021,000 while EBIT is 565,851,000, and D&A is ~625,799,000.

1,305,021,000 - 625,799,000 - 113,370,000 = 565,852,000 ≈ EBIT. Yes!

So "Gross Profit" = EBIT + D&A + Impairment = EBITDA + Impairment? Or is impairment part of operating expenses?

Actually: 1,305,021,000 (Gross Profit/EBITDA?) - 113,370,000 (Impairment) - 625,799,000 (D&A) = 565,852,000 EBIT.

So 1,305,021,000 = EBIT + D&A + Impairment. But is impairment part of EBITDA? Typically no, EBITDA is before impairment. But in some definitions, operating EBITDA includes impairment.

For S&P purposes, Adjusted_EBITDA typically excludes impairment (adds back D&A only to EBIT). So:
EBITDA = EBIT + D&A = 565,851,000 + 625,799,000 = **1,191,650,000 EUR**

Or using cash flow D&A: 565,851,000 + 594,636,000 = **1,160,487,000 EUR**

I'll use the income statement D&A as it's more consistent with the reported figures: **1,191,650,000 EUR**

But wait - the cash flow D&A of 594,636,000 might be more accurate (excluding amortization of intangibles from acquisitions perhaps). Let me use a blended approach or the cash flow figure as it's standard for S&P.

Actually, for S&P, they prefer to use reported or reconstructed EBITDA. Let me use:
EBITDA = EBIT + Depreciation and Amortization (from cash flow statement) = 565,851,000 + 594,636,000 = **1,160,487,000 EUR**

Now, adjustments for S&P:
- **Leases**: If we capitalized leases, we need to add back lease expenses to EBITDA. Under IFRS 16, lease expenses are already replaced by depreciation and interest, so EBITDA already includes the depreciation portion. For operating lease adjustments (pre-IFRS 16 style), we'd add back lease expense. But under IFRS 16, this is already in D&A. So no adjustment needed, or we could add back the interest portion of lease liability.

Actually, for S&P methodology with IFRS 16: since leases are already capitalized and included in debt, the EBITDA already reflects this (as depreciation). No further lease adjustment to EBITDA typically needed.

- **Nonrecurring items**: 
  - "Other Income Expense From Subsidiaries Jointly Controlled Entities And Associates": 27,897,000 - this is below EBIT, so already excluded
  - Need to check for nonrecurring gains/losses in EBIT
  
Looking at the income statement, I don't see clear nonrecurring items broken out. The "Impairment Loss" of 113,370,000 might include nonrecurring elements, but impairment is typically considered part of normal operations for S&P unless specifically identified as nonrecurring.

- **Joint venture proportional EBITDA**: 
  - "Share Of Profit Loss Of Associates And Joint Ventures Accounted For Using Equity Method": 17,793,000
  - This is equity pickup, already in EBIT? No, it's after EBIT. Looking at the structure:
    - EBIT: 565,851,000
    - Finance Income: 25,962,000
    - Finance Costs: (111,670,000)
    - Share of profit of associates: 17,793,000
    - Profit before tax: 497,937,000

  So share of associates is AFTER EBIT. For S&P, if we want proportional consolidation, we'd add back the equity income and add proportional EBITDA. But without proportional financials, we typically just add back the equity income to get closer to proportional EBIT, or leave as is.

  For regulated utilities, S&P may or may not adjust for JVs. Given limited data, I'll add back the equity income to get a broader measure: +17,793,000

- **Other normalization adjustments**: None identified clearly.

Adjusted_EBITDA = 1,160,487,000 + 17,793,000 = **1,178,280,000 EUR**

Or if using income statement D&A: 1,191,650,000 + 17,793,000 = **1,209,443,000 EUR**

Let me also consider if we should use the "Gross Profit" 1,305,021,000 as a starting point. This might be closer to operating EBITDA before impairment. If we subtract impairment (as nonrecurring/normalizing): 1,305,021,000 - 113,370,000 = 1,191,651,000, then add D&A... no that's double counting.

Actually, I think the cleanest approach is:
EBITDA = EBIT + D&A (cash flow) = 565,851,000 + 594,636,000 = 1,160,487,000

Plus equity income add-back: 17,793,000

Adjusted_EBITDA = **1,178,280,000 EUR**

Wait - I need to reconsider. The cash flow "Adjustments For Depreciation And Amortisation Expense" of 594,636,000 is added back to net income to get to operating cash flow before working capital. Let me verify this equals the D&A expense.

From cash flow:
- Profit: 311,160,000
- + D&A: 594,636,000
- + Impairment: 67,680,000
- + Other adjustments...
- = Cash flow before working capital: 1,062,464,000

But EBIT is 565,851,000. The reconciliation from profit to operating cash flow starts with net income, not EBIT.

Actually, let me verify: 311,160,000 (net income) + 594,636,000 + 67,680,000 + ... other items = 1,062,464,000.

The "Cash Flows From Used In Operations Before Changes In Working Capital" is 1,062,464,000. This is roughly: Net income + D&A + Impairment + Interest expense (net) + Other non-cash items - Dividends from JVs + etc.

Roughly: 311,160,000 + 594,636,000 + 67,680,000 + (111,670,000 - 25,962,000 interest) + 14,167,000 (provisions) + ... = ?

This gets complicated. Let me just use the standard EBITDA definition and the reported figures.

Actually, for S&P regulated utilities, they often use "Funds From Operations" (FFO) as the preferred metric, not EBITDA. But the question asks for Debt/EBITDA.

Let me use a simpler approach: EBITDA = Revenue - Cash Operating Costs (excluding D&A and impairment)

Revenue: 5,138,245,000
Less: Operating Expenses (external + employee): 3,861,121,000
= Gross operating cash flow: 1,277,124,000

But reported "Gross Profit" is 1,305,021,000. The difference might be other operating income included in gross profit calculation.

Let me use: EBITDA = 1,305,021,000 (Gross Profit/MOL) + adjustments. Actually, in Italian reporting, MOL is EBITDA before impairment and D&A. So:
EBITDA = 1,305,021,000 - this already IS EBITDA if it's MOL!

Wait, let me re-verify with EBIT:
If EBITDA = 1,305,021,000, then EBIT = EBITDA - D&A - Impairment = 1,305,021,000 - 625,799,000 - 113,370,000 = 565,852,000. Yes! Matches!

So "Gross Profit" = **EBITDA = 1,305,021,000 EUR**

This is the cleanest measure. Now for S&P adjustments:
- Add back nonrecurring losses / subtract nonrecurring gains: Not clearly identified
- Joint venture proportional EBITDA: Add equity income 17,793,000 (to get closer to proportional measure, or add proportional EBITDA if we had it)

For S&P, when they proportionalize JVs, they add the full proportional EBITDA, not just equity income. Without JV financials, adding back equity income is a proxy.

Adjusted_EBITDA = 1,305,021,000 + 17,793,000 = **1,322,814,000 EUR**

Or if we consider that equity income is already "net" (after their D&A and interest), we might gross it up. But without data, just adding back is reasonable.

Let me also consider if there are any nonrecurring items to normalize. The impairment of 113,370,000 - is this recurring? For utilities, impairment can be recurring. S&P typically doesn't adjust out impairment unless clearly nonrecurring.

Also, "Other Income" of 181,066,000 - is this recurring? It increased from 156,032,000. This seems somewhat stable. I'll leave as is.

Final Adjusted_EBITDA = **1,322,814,000 EUR** (with JV add-back) or **1,305,021,000 EUR** (without).

For conservative S&P approach, let me use 1,305,021,000 as base, and maybe add half the JV impact or full. I'll use **1,322,814,000 EUR**.

Actually, rethinking: S&P typically uses "EBITDA" as reported with their specific adjustments. For regulated utilities, they may not proportionalize JVs unless significant. Let me check if JVs are significant: Equity income is 17,793,000 vs EBIT of 565,851,000 = 3.1%. Not huge.

I'll use Adjusted_EBITDA = **1,305,021,000 EUR** (using reported EBITDA/MOL) or with D&A reconstruction.

Wait - I want to verify: Is "Gross Profit" here truly EBITDA? Let me check 2021:
- 2021 Gross Profit: 1,256,075,000
- 2021 EBIT: 581,101,000
- 2021 "Ammortamenti E Accantonamenti": 588,768,000
- 2021 Impairment: 86,207,000

1,256,075,000 - 588,768,000 - 86,207,000 = 581,100,000 ≈ 581,101,000. Yes!

So "Gross Profit" = EBITDA in this reporting format.

## Step 4: Calculate Adjusted_Debt / Adjusted_EBITDA

Using:
- Adjusted_Debt = 4,894,762,000 EUR
- Adjusted_EBITDA = 1,305,021,000 EUR (conservative, no JV adjustment)

Ratio = 4,894,762,000 / 1,305,021,000 = **3.75x**

Or with JV adjustment to EBITDA:
- Adjusted_EBITDA = 1,322,814,000
- Ratio = 4,894,762,000 / 1,322,814,000 = **3.70x**

Let me also try with cash flow D&A EBITDA:
- EBITDA = 565,851,000 + 594,636,000 = 1,160,487,000
- Ratio = 4,894,762,000 / 1,160,487,000 = **4.22x**

This is quite different. Which D&A is correct? The income statement "Ammortamenti E Accantonamenti" of 625,799,000 includes "accantonamenti" (provisions/accruals), not just D&A. The cash flow "Adjustments For Depreciation And Amortisation Expense" of 594,636,000 is cleaner D&A.

But "Gross Profit" reconciles to EBIT with the 625,799,000 figure, not 594,636,000. So for consistency with reported "Gross Profit", I should use 625,799,000.

Actually, let me verify: 1,305,021,000 - 625,799,000 - 113,370,000 = 565,852,000. Yes matches.

So EBITDA = 1,305,021,000 is correct per this reporting.

But wait - is "Gross Profit" = EBITDA or is it something else? Let me check if it includes other income/expense items that should be excluded.

Looking at the income statement structure:
- Revenue: 5,138,245,000
- Operating Expense: 3,861,121,000
- Gross Profit: 1,305,021,000? But 5,138,245 - 3,861,121 = 1,277,124, not 1,305,021.

Difference: 27,897,000. This is exactly "Other Income Expense From Subsidiaries Jointly Controlled Entities And Associates"! 

Wait no, that's 27,897,000 and it's below EBIT. Let me check other items.

Actually, looking more carefully: "Other Income" is 181,066,000. This is part of revenue. So total revenue-like items = 4,957,179,000 + 181,066,000 = 5,138,245,000. This matches "Revenue".

Then "Operating Expense" = 3,861,121,000. But this might not include all costs that are in cost of sales.

Hmm, let me look at this differently. In Italian reporting:
- "Ricavi Da Vendita E Prestazioni" = Revenues from sales and services: 4,957,179,000
- "Other Income" = Other income: 181,066,000
- Total revenues = 5,138,245,000

Costs:
- "Costi Esterni" = External costs: 3,556,055,000
- "Employee Benefits Expense" = Personnel costs: 305,066,000
- Total operating costs = 3,861,121,000

"Gross Profit" (MOL) = 1,305,021,000

But 5,138,245,000 - 3,861,121,000 = 1,277,124,000 ≠ 1,305,021,000.

The difference is 27,897,000. This matches "Other Income Expense From Subsidiaries Jointly Controlled Entities And Associates" which is 27,897,000. But this is shown BELOW EBIT, not above.

Wait, let me re-read: "Other Income Expense From Subsidiaries Jointly Controlled Entities And Associates" - this might be dividends or income from subsidiaries, not equity method. Actually, it's listed between Gross Profit and Impairment, so it's part of operating income!

Looking at the order:
1. Gross Profit: 1,305,021,000
2. Margine Operativo Lordo Di Cui Verso Parti Correlate: 82,855,000
3. Impairment Loss: 113,370,000
4. Ammortamenti E Accantonamenti: 625,799,000
5. Other Income Expense From Subsidiaries...: 27,897,000
6. Profit Loss From Operating Activities: 565,851,000

Wait, that doesn't add up. Let me try: 1,305,021,000 - 113,370,000 - 625,799,000 + 27,897,000 = 593,749,000 ≠ 565,851,000.

Hmm, maybe "Other Income Expense From Subsidiaries..." is negative or the order is different.

Actually, looking at the original data format, these are just listed facts, not necessarily in order. Let me not rely on ordering.

Let me use the verified relationship: Gross Profit - Impairment - D&A = EBIT. This works: 1,305,021,000 - 113,370,000 - 625,799,000 = 565,852,000 ≈ 565,851,000.

So EBITDA = Gross Profit = 1,305,021,000 is correct.

Now, for the debt calculation, let me reconsider if I should include more items:

Looking at "Noncurrent Provisions" = 218,025,000. This includes:
- Employee benefits: 112,989,000
- Other provisions: 105,036,000

Should other provisions be included as debt-like? For regulated utilities, some provisions may be regulatory in nature (like decommissioning, environmental). These can be debt-like. Let me include all noncurrent provisions: 218,025,000.

Also "Current Provisions" - not explicitly shown, but "Other Current Liabilities" = 632,259,000 might include some.

Actually, let me check: "Noncurrent Provisions" = 218,025,000. "Other Noncurrent Liabilities" = 399,628,000. These might include deferred revenue, regulatory liabilities, etc.

For S&P, debt-like items include:
- Debt (financial liabilities)
- Leases (if not already in debt)
- Pension deficits
- Guarantees
- Hybrid equity portion
- Other debt-like: deferred taxes (if liability), put options, etc.

I'll stick with my conservative approach but add other noncurrent provisions as potentially debt-like:

Revised Adjusted_Debt:
- Reported debt: 5,341,681,000
- Noncurrent provisions (other than employee benefits): 105,036,000
- Employee benefits provision (pension-like): 112,989,000
- Less cash: (559,908,000)
= 4,999,798,000 EUR

Or keeping just employee benefits as clearly debt-like: 4,894,762,000 EUR

Let me check S&P methodology for regulated utilities specifically: "Where substantial seasonal working capital requirements...distort leverage measures, we adjust inventory and debt balances by netting the value of inventory against outstanding short-term borrowings." Not applicable here.

For regulated utilities, S&P also mentions "purchased power methodology" for integrated electric utilities - not clearly applicable.

I'll use Adjusted_Debt = 4,894,762,000 (with pension/employee benefits) or 5,000,000,000 rounded.

Actually, let me also consider "Deferred Tax Assets" and "Deferred Tax Liabilities" - not explicitly shown. There are "Current Tax Assets" and "Current Tax Liabilities" but these are working capital, not debt-like.

Final calculation with precise numbers:
Adjusted_Debt = 4,722,263,000 + 619,418,000 + 112,989,000 - 559,908,000 = 4,894,762,000

Adjusted_EBITDA = 1,305,021,000

Ratio = 4,894,762,000 / 1,305,021,000 = 3.7507...

Rounded: **3.75**

With EBITDA including JV add-back: 1,322,814,000
Ratio = 4,894,762,000 / 1,322,814,000 = 3.7003... ≈ **3.70**

Given S&P typically makes JV adjustments for significant equity investments, and 3.1% is borderline, I'll use the more conservative (higher ratio) of **3.75**.

Actually, let me reconsider one more time. Should I use average debt or year-end debt? S&P typically uses year-end or average. For ratios, they often use latest available, which is year-end 2022 (reported 2023-01-01).

Also, should I use 2022 average debt? (2022 beginning + end)/2 = (4,791,979,000 + 285,222,000 + ... wait, need 2022-01-01 debt).

At 2022-01-01:
- Other Noncurrent Financial Liabilities: 4,791,979,000
- Other Current Financial Liabilities: 285,222,000
- Total debt: 5,077,201,000

Average debt = (5,077,201,000 + 5,341,681,000)/2 = 5,209,441,000

But S&P debt ratio typically uses point-in-time debt, not average.

For EBITDA, should I use LTM or average? Typically LTM (2022 full year).

Let me also verify my debt at 2022-01-01 includes leases: Right-of-use assets at 2022-01-01 were 53,096,000, suggesting lower lease liabilities.

Actually, I realize I need to check if "Other Noncurrent Financial Liabilities" and "Other Current Financial Liabilities" include lease liabilities under IFRS 16. They should.

Given the complexity, let me also try an alternative EBITDA calculation using cash flow approach:

From cash flow: "Cash Flows From Used In Operations Before Changes In Working Capital" = 1,062,464,000

This is roughly: Net Income + D&A + Impairment + Interest(net) + Other non-cash - Equity income + ...

To get to EBITDA from this:
- Start with 1,062,464,000
- Subtract: Interest paid (114,121,000) - Interest received (29,243,000)? Actually interest paid is in financing, interest received in investing.

Actually, "Cash Flows From Used In Operations Before Changes In Working Capital" includes:
- Net income: 311,160,000
- D&A: 594,636,000
- Impairment: 67,680,000
- Provisions change: 14,167,000
- Employee benefits change: -19,158,000
- Finance costs adjustment: 85,708,000
- Other: ?

Sum of identified: 311,160,000 + 594,636,000 + 67,680,000 + 14,167,000 - 19,158,000 + 85,708,000 = 1,054,193,000. Close to 1,062,464,000.

To get EBITDA, I'd add back interest and taxes to EBIT, or use:
EBITDA ≈ Cash flow before WC + Interest paid - Interest received + Taxes paid - Working capital changes... this gets messy.

I'll stick with EBITDA = 1,305,021,000 from the income statement reconstruction.

One more check: Is "Gross Profit" truly EBITDA, or does it exclude some operating costs that should be in EBITDA?

In standard Italian format:
MOL (Margine Operativo Lordo) = Revenues - External costs - Personnel costs - Other operating costs (before D&A, impairment)

But "Gross Profit" here is 1,305,021,000 and EBIT is 565,851,000, with D&A+Impairment = 739,169,000. The math checks: 1,305,021,000 - 739,169,000 = 565,852,000.

So yes, "Gross Profit" = EBITDA.

Final answer: 4,894,762,000 / 1,305,021,000 = 3.75

Let me also try if I should include more debt-like items:
- "Other Noncurrent Liabilities" = 399,628,000 - could include deferred revenue, regulatory liabilities
- "Noncurrent Contract Liabilities" = 5,452,905,000 - this is significant! Is this debt-like?

"Noncurrent Contract Liabilities" - in IFRS 15, this is deferred revenue (payments received in advance). For utilities with customer deposits or prepayments, this is operating, not debt-like. But for long-term contracts, some portion might be debt-like.

However, 5.4 billion is huge. Let me check if this is regulatory in nature. For regulated utilities, "contract liabilities" often relate to regulatory mechanisms - revenue collected but not yet earned, or future service obligations. These are typically NOT debt-like for S&P purposes as they represent operating obligations, not financial obligations.

I'll exclude contract liabilities from debt.

Similarly, "Other Noncurrent Liabilities" of 399,628,000 - likely deferred tax, environmental provisions, etc. Some might be debt-like but hard to identify.

My final answer remains **3.75**.

But wait - I want to double-check one thing. The methodology says for regulated utilities: "For integrated electric utilities that meet native load obligations partly by using third-party power contracts, we use our purchased power methodology to adjust measures for such contracts' debt-like obligations."

ACEA is a multi-utility with electricity distribution. Do they have purchased power contracts? Likely yes, but we don't have data on third-party power contracts. Without specific data, I can't make this adjustment.

Also: "We deconsolidate securitized debt (and associated revenue and expense) that has been accorded specialized recovery provisions." No evidence of securitization in the data.

Final verification of numbers:
- Debt 2022 year-end: 4,722,263,000 + 619,418,000 = 5,341,681,000
- Less cash: 559,908,000
- Plus pension/employee benefits provision: 112,989,000
- Net adjusted debt: 4,894,762,000

EBITDA: 1,305,021,000

Ratio: 3.7507...
