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

## Step 1: Identify the relevant industry

Italgas S.p.A. is Italy's largest natural gas distribution company. It operates regulated gas distribution networks. This clearly falls under **Regulated Utilities** (Gas subsector).

## Step 2: Estimate 2021 Adjusted EBITDA

The fiscal year labeled "2021-01-01 - 2022-01-01" represents FY2021.

**EBITDA reconstruction:**
- Operating Profit (EBIT) = 583,231,000 EUR
- D&A = 445,251,000 EUR
- EBITDA = 583,231 + 445,251 = 1,028,482,000 EUR

**Lease adjustments:** S&P typically adds back lease costs as part of EBITDA adjustments. From the cash flow statement, cash outflow for leases in FY2021 = 21,529,000 EUR. Under IFRS 16, leases are already capitalized, so D&A already includes right-of-use asset depreciation and interest is in finance costs. The EBITDA as calculated above already captures the lease effect through IFRS 16 treatment. However, S&P may add back the lease depreciation component (already included in D&A above) - so EBITDA as computed should be sufficient. No additional adjustment needed since IFRS 16 is already reflected.

**Adjusted EBITDA (2021) ≈ 1,028,482,000 EUR**

## Step 3: Estimate 2021 FFO

**Cash interest:**
- Finance costs = 64,645,000 EUR
- Finance income = 3,630,000 EUR
- Net interest paid (from cash flow) = 59,783,000 - 3,630,000 = 56,153,000 EUR
- I'll use cash interest paid: 59,783,000 and cash interest received: 3,630,000
- Net cash interest = 59,783 - 3,630 = 56,153,000 EUR

**Cash taxes:**
- Income taxes paid = 206,923,000 EUR

**FFO (2021) = 1,028,482 - 56,153 - 206,923 = 765,406,000 EUR**

## Step 4: Estimate 2021 Adjusted Debt

Balance sheet as of 2022-01-01 (end of FY2021):

**Reported debt:**
- Short-term financial liabilities = 591,188,000
- Long-term financial liabilities = 5,785,707,000
- Other current financial liabilities = 290,000
- Other noncurrent financial liabilities = 6,283,000
- Total reported debt = 591,188 + 5,785,707 + 290 + 6,283 = 6,383,468,000 EUR

**Pension deficit:**
- Noncurrent provisions for employee benefits = 95,648,000 EUR

**Other provisions (S&P may treat some as debt-like):**
- Other long-term provisions = 159,506,000 EUR (these may include asset retirement obligations - common for utilities)

**Lease liabilities** are already included in the reported debt under IFRS 16 (cash outflow for leases = 21,529,000 suggests lease liabilities are part of financial liabilities).

**Cash deduction:**
- Cash and equivalents = 1,391,763,000 EUR
- For S&P, typically only a portion of cash is deducted for regulated utilities. S&P generally allows netting of surplus cash. For a regulated utility, I'll be conservative and deduct a reasonable portion. However, for regulated utilities, S&P may not deduct all cash. Let me use a moderate approach - deduct most cash but keep some operating cash (~2% of revenue as operating minimum).
- Operating cash minimum ≈ 2% × 2,163,232 ≈ 43,265,000
- Eligible cash = 1,391,763 - 43,265 ≈ 1,348,498,000 EUR

**Adjusted Debt (2021):**
= 6,383,468 + 95,648 + 159,506 - 1,348,498
= 5,290,124,000 EUR

## Step 5: 2021 Adjusted Debt / Adjusted EBITDA

= 5,290,124 / 1,028,482 = **5.14x**

## Step 6: 2021 FFO / Adjusted Debt

= 765,406 / 5,290,124 = **14.5%**

## Step 7: Estimate 2022 Adjusted EBITDA

FY2022 = "2022-01-01 - 2023-01-01"

- Operating Profit = 641,338,000 EUR
- D&A = 479,186,000 EUR
- EBITDA = 641,338 + 479,186 = 1,120,524,000 EUR

**Adjusted EBITDA (2022) ≈ 1,120,524,000 EUR**

## Step 8: Estimate 2022 FFO

**Cash interest:**
- Cash interest paid = 53,720,000
- Cash interest received = 4,043,000
- Net cash interest = 53,720 - 4,043 = 49,677,000 EUR

**Cash taxes:**
- Income taxes paid = 152,372,000 EUR

**FFO (2022) = 1,120,524 - 49,677 - 152,372 = 918,475,000 EUR**

## Step 9: Estimate 2022 Adjusted Debt

Balance sheet as of 2023-01-01 (end of FY2022):

**Reported debt:**
- Short-term financial liabilities = 142,437,000
- Long-term financial liabilities = 6,402,913,000
- Other current financial liabilities = 290,000
- Other noncurrent financial liabilities = 34,000
- Total = 142,437 + 6,402,913 + 290 + 34 = 6,545,674,000 EUR

**Pension deficit:** 69,917,000 EUR

**Other provisions:** 144,277,000 EUR

**Cash deduction:**
- Cash = 451,946,000 EUR
- Operating minimum ≈ 2% × 2,312,476 ≈ 46,250,000
- Eligible cash = 451,946 - 46,250 = 405,696,000 EUR

**Adjusted Debt (2022):**
= 6,545,674 + 69,917 + 144,277 - 405,696
= 6,354,172,000 EUR

## Step 10: 2022 Adjusted Debt / Adjusted EBITDA

= 6,354,172 / 1,120,524 = **5.67x**

## Step 11: 2022 FFO / Adjusted Debt

= 918,475 / 6,354,172 = **14.5%**

## Step 12: Credit Trend Classification

**Signal 1 - Leverage:**
Change = 5.67 - 5.14 = +0.53x → ≥ +0.2x → **Deteriorating**

**Signal 2 - Cash-flow coverage:**
Change = 0.1445 - 0.1447 = -0.002 → Between -0.03 and +0.03 → **Stable**

**Combining:** One Stable, one Deteriorating → Return the non-Stable category → **Deteriorating**

The leverage increase of +0.53x is significant (well above the 0.2x threshold), driven by substantial debt increase from acquisitions (investments in change in scope of consolidation jumped from 21M to 875M) while cash was drawn down significantly. The FFO/Debt ratio remained essentially flat because EBITDA growth offset the debt increase to some degree.
