Let's go through the steps.

**Step 1 – Identify the relevant industry**

VERBUND AG is primarily an electricity utility, with a large share of revenue from electricity generation (especially hydropower), grid operations, and electricity sales.  
Given the description, it does not appear to be an oil & gas E&P, and is not purely transportation infrastructure.  
It has regulated grid operations and unregulated power generation (renewables).  
The S&P methodology describes **Regulated Utilities** and **Unregulated Power and Gas** as applicable.  
Since VERBUND has regulated grid revenue (~€1.3bn) and large unregulated generation (~€8.7bn electricity sales minus grid), it likely falls under **Unregulated Power and Gas** for its generation business. However, grid is regulated. For simplicity, S&P might classify it under Unregulated Power and Gas with some regulated components, and we should check for adjustments.

We will proceed with the **Unregulated Power and Gas** methodology with attention to adjustments (leases, pensions, JV, derivatives, hybrid debt, etc.).

**Step 2 – Estimate Adjusted Debt**

We need to find or reconstruct:
- **Reported debt** (current + noncurrent financial liabilities)
- Add **leases** (if not already in debt; here, right-of-use assets ~€146.6m, presumably already in financial liabilities under IFRS 16, but we should check)
- Add **pension deficit** (if any)
- Add **guarantees** (if disclosed – none provided)
- Add **hybrid debt portion** (if any – none provided)
- Add **other debt-like items** (possibly some derivatives – S&P may add adjusted net derivative liabilities)
- Subtract **eligible cash** (cash & cash equivalents)

From the balance sheet at 2023-01-01 (fiscal year end 2022):
- Noncurrent financial liabilities: €2,844,559,000
- Current financial liabilities: €1,109,297,000
- Total reported debt = €3,953,856,000

Leases:
- Right-of-use assets: €146,613,000 (already included under IFRS 16 in financial liabilities, so no extra add unless we need to gross up; S&P usually adds if not captured – here it likely is, so no adjustment needed)

Pension deficit:
- Not explicitly given as separate balance sheet item, but we can check for "Reserve of remeasurements of defined benefit plans" – negative €205,455,000 in equity at 2023-01-01. This may imply underfunded pension.  
S&P adds the net pension deficit to debt. Here, assume this is the deficit: +€205,455,000.

Cash:
- Cash and cash equivalents: €409,252,000 (eligible cash, subtract)

Derivative adjustments:
- S&P may add 50% of net derivative liabilities in some cases. Net derivative position:
  - Noncurrent derivative financial assets: €437,341,000
  - Current derivative financial assets: €1,833,683,000
  - Noncurrent derivative financial liabilities: €1,069,177,000
  - Current derivative financial liabilities: €1,491,588,000
  - Net derivative liabilities = (1,069,177,000 + 1,491,588,000) – (437,341,000 + 1,833,683,000) = €289,741,000 net liability
  - S&P may add 50% of this: €144,870,500

No guarantees or hybrids mentioned.

**Adjusted Debt** =
Reported debt: €3,953,856,000  
+ Pension deficit: €205,455,000  
+ Derivative adjustment: €144,870,500  
– Cash: €409,252,000  
= **€3,894,929,500**

**Step 3 – Estimate Adjusted EBITDA**

Reported EBITDA for 2022: €3,160,679,000

Adjustments:
- Leases: Under IFRS 16, EBITDA already excludes lease depreciation and interest. S&P adds back operating lease expense if not already adjusted. Here, leases are likely already finance leases, so no change.
- Pension adjustments: Replace service cost with actual contributions if available (not given), so skip.
- Non-recurring items: Impairment loss €197,761,000 – reversal €125,973,000 = net €71,788,000 charge. This may be added back partly.  
- Share of profit from equity-accounted JVs: €4,293,000 – S&P may include proportional EBITDA but data not given, skip.
- Valuation of energy derivatives: -€857,961,000 (this is a non-cash item, but it is included in EBITDA per note; S&P may adjust out unrealized gains/losses for EBITDA calculation. This is a major swing; we might add this back if it’s a non-cash charge.)
- Other adjustments: none significant.

If we add back impairment net charge: €71,788,000 + add back valuation loss on derivatives €857,961,000, then:

Adjusted EBITDA = 3,160,679,000 + 71,788,000 + 857,961,000 = **€4,090,428,000**

**Step 4 – Ratio**

Adjusted Debt / Adjusted EBITDA = 3,894,929,500 / 4,090,428,000 ≈ **0.95**
