I'll work through this step-by-step for VINCI.

## Step 1: Identify the relevant industry

VINCI is a major French concessions and construction company. Its key businesses include:
- **Concessions** (motorways via ASF/Cofiroute/Escota, airports via VINCI Airports)
- **Contracting** (VINCI Energies, Eurovia, VINCI Construction)

The **Transportation Infrastructure** methodology is most relevant for the concessions business (toll roads, airports). However, VINCI is a diversified group with significant contracting/construction operations. I'll apply the Transportation Infrastructure framework where relevant, and general corporate methodology for the overall assessment.

## Step 2: Estimate 2021 Adjusted EBITDA

Starting from the income statement for 2021:

**Profit from Operating Activities (Recurring):** €4,464M

Add back:
- **D&A:** €3,219M
- **Share-based payments (non-cash):** €84M (adjust for cash vs. non-cash; the adjustment in CF statement shows €84M)

**Reported EBITDA (approximation):** 
Operating profit (recurring) + D&A = 4,464 + 3,219 = €7,683M

**S&P Adjustments:**
- **Lease adjustments:** Add back lease depreciation (included in D&A) and lease interest. Lease liabilities (2022-01-01): Current €524M + Noncurrent €1,574M = €2,098M. Lease interest in 2021: €43M. Lease payments in financing: €631M. So lease depreciation ≈ 631 - 43 = €588M (already in D&A). The S&P adjustment adds operating lease rent back and replaces with depreciation - but since IFRS 16 is already applied, the main adjustment is already captured. I'll add lease interest of €43M to EBITDA.
- **Non-recurring items:** Non-recurring operating loss 2021: -€26M (loss, add back). Impairment provisions: €206M (add back if non-recurring).
- **Share-based payment (non-cash):** Already included in operating expenses; the CF adjustment of €84M suggests this is non-cash — but S&P typically doesn't add this back.

**Adjusted EBITDA 2021:**
= 7,683 + 43 + 26 + 206 = ~€7,958M

Let me simplify: Using the cash flow approach:
Cash flows from operations before WC changes = €7,884M. This already adds back D&A (3,219), provisions/impairments (206), share-based (84), removes gains (-27), fair value (-54), undistributed equity (18), adds net finance costs (658), lease interest (43), and income tax (1,625).

So operating cash flow before WC = €7,884M. This is close to an EBITDA-like measure but includes finance costs and taxes added back.

For S&P Adjusted EBITDA, I'll use:
**Adjusted EBITDA ≈ €7,958M** (rounding, I'll use ~€7,900M for conservatism)

Let me be more precise:
- EBITDA from recurring operations = 4,464 + 3,219 = 7,683
- Add lease interest: +43
- Add non-recurring loss: +26
- Adjusted EBITDA 2021 ≈ **€7,752M**

I'll exclude the €206M impairment/provisions as that may be recurring. Let me keep it simpler and consistent.

**Adjusted EBITDA 2021 ≈ €7,752M**

## Step 3: Estimate 2021 FFO

**FFO = Adjusted EBITDA - cash interest - cash taxes**

- Cash interest paid: €557M (interest paid classified as operating) + €47M (finance costs paid classified as operating) = but looking more carefully, "Interest Paid And Interest Received Classified As Operating Activities" = €557M (net). Let me use gross: Gross finance costs = €674M. But cash interest should be net. The CF shows interest paid/received as operating = €557M. This appears to be net cash interest.
- But we also need to add lease interest back if we're treating leases separately. Cash lease payments = €631M (financing). Lease interest = €43M.
- Cash taxes: €1,213M

**FFO 2021 = 7,752 - 557 - 1,213 = €5,982M**

Wait, let me reconsider. The €557M likely represents net interest paid (excluding lease interest since that's in financing). 

**FFO 2021 ≈ €5,982M**

## Step 4: Estimate 2021 Adjusted Debt

Balance sheet as of Jan 1, 2022 (end of FY2021):

**Reported financial debt:**
- Noncurrent bonds: €22,212M
- Other noncurrent borrowings: €2,757M
- Short-term borrowings: €5,769M
- Total reported debt = €30,738M

**S&P Adjustments:**
- **Lease liabilities:** Current €524M + Noncurrent €1,574M = €2,098M
- **Pension deficit:** Noncurrent provisions for employee benefits = €1,459M
- **Derivative liabilities (net):** Noncurrent derivative liabilities €422M + Current €513M = €935M; Noncurrent derivative assets €575M + Current €291M = €866M. Net = €69M (liability). Typically not added unless debt-like.

**Gross adjusted debt:** 30,738 + 2,098 + 1,459 = €34,295M

**Subtract surplus cash:** 
Cash = €11,065M. S&P typically allows some cash netting but not all. Cash on BS differs from CF statement cash (€10,188M). The difference relates to restricted cash or bank overdrafts.

For S&P, typically a portion of cash is deducted. For infrastructure companies, S&P might net a portion. Let me assume S&P nets modest operating cash (say €500M-1,000M is operational). I'll be conservative and not net significant cash for an infrastructure/construction company with large working capital needs.

Let's assume S&P accessible cash ≈ a portion. Given VINCI's large construction operations, significant cash is operational. I'll assume ~€2,000M is surplus/nettable.

**Adjusted Debt 2021 ≈ 34,295 - 2,000 = €32,295M**

Actually, S&P for large infrastructure companies with significant cash positions may net more. Let me use a more standard approach and not net any cash (conservative), or net a small amount.

Let me use **Adjusted Debt 2021 ≈ €33,000M** (netting ~€1,300M of surplus cash).

## Step 5: 2021 Adjusted Debt / Adjusted EBITDA

= 33,000 / 7,752 = **4.26x**

## Step 6: 2021 FFO / Adjusted Debt

= 5,982 / 33,000 = **18.1%**

## Step 7: Estimate 2022 Adjusted EBITDA

**Profit from Operating Activities (Recurring) 2022:** €6,481M
**D&A 2022:** €3,613M

**EBITDA from recurring operations:** 6,481 + 3,613 = €10,094M

**S&P Adjustments:**
- Lease interest: +€48M
- Non-recurring items 2022: +€8M (gain, subtract) → -8M
- Actually, non-recurring was +€8M (income), so we subtract it.

**Adjusted EBITDA 2022 = 10,094 + 48 - 8 = €10,134M**

Let me use **Adjusted EBITDA 2022 ≈ €10,134M**

## Step 8: Estimate 2022 FFO

- Cash interest (from CF): "Interest Paid And Interest Received Classified As Operating Activities" = €563M
- Cash taxes: €1,603M

**FFO 2022 = 10,134 - 563 - 1,603 = €7,968M**

## Step 9: Estimate 2022 Adjusted Debt

Balance sheet as of Jan 1, 2023 (end of FY2022):

**Reported financial debt:**
- Noncurrent bonds: €20,425M
- Other noncurrent borrowings: €3,205M
- Short-term borrowings: €6,368M
- Total reported debt = €29,998M

**S&P Adjustments:**
- Lease liabilities: €522M + €1,580M = €2,102M
- Pension deficit: €1,149M

**Gross adjusted debt:** 29,998 + 2,102 + 1,149 = €33,249M

**Subtract surplus cash:** Cash = €12,578M. Using same methodology, net ~€1,500M.

**Adjusted Debt 2022 ≈ 33,249 - 1,500 = €31,749M**

Let me keep consistent: **Adjusted Debt 2022 ≈ €32,000M**

## Step 10: 2022 Adjusted Debt / Adjusted EBITDA

= 32,000 / 10,134 = **3.16x**

## Step 11: 2022 FFO / Adjusted Debt

= 7,968 / 32,000 = **24.9%**

## Step 12: Classify the credit trend

**Signal 1: Leverage (Adjusted Debt / Adjusted EBITDA)**
Change = 3.16 - 4.26 = **-1.10x**
This is ≤ -0.2x → **Improving**

**Signal 2: Cash-flow coverage (FFO / Adjusted Debt)**
Change = 0.249 - 0.181 = **+0.068**
This is ≥ +0.03 → **Improving**

Both signals clearly agree: **Improving**

The improvement is driven by strong revenue growth (+24.6%), significant operating profit improvement, and modest debt reduction, resulting in substantially better leverage and coverage ratios.
