**Step 1: Identify the relevant industry for "VERBUND AG"**

VERBUND AG is an Austrian electricity company. The provided facts show significant revenue from the "Sale of Electricity" and "Grid Revenue". The company operates hydroelectric power plants and manages the transmission grid.
Looking at the provided methodologies:
1.  **Regulated Utilities**: This section applies to companies providing essential infrastructure services subject to comprehensive regulation. VERBUND operates the high-voltage grid in Austria (a natural monopoly/regulatory environment) and generates power. While generation can be unregulated (merchant), the presence of significant grid revenue and the nature of the utility sector in Europe often leads to a hybrid assessment. However, the prompt provides specific methodologies for "Regulated Utilities", "Oil And Gas E&P", "Unregulated Power And Gas", and "Transportation Infrastructure".
2.  **Unregulated Power And Gas**: This applies to companies without protective rate regulation. VERBUND's generation business is largely exposed to market prices (merchant), but its grid business is regulated.
3.  **Regulated Utilities**: The text states, "We assess regulatory advantage... for regulated utilities." It also notes that for integrated electric utilities, adjustments might be needed. Given VERBUND's status as a major national utility with a regulated grid component and significant hydro generation (which often has stable, low-cost characteristics akin to regulated assets or strongly protected unregulated revenue due to low variable costs), and the fact that "Regulated Utilities" is the primary category for traditional electric utilities with grid assets, we will evaluate which framework fits best.
    *   VERBUND's revenue mix: 2022 Electricity Sales ~8.7B EUR, Grid ~1.3B EUR. The majority is generation/trading.
    *   However, S&P often treats large European utilities with significant regulated grid assets and low-risk generation (hydro) under a framework that acknowledges the stability of the regulated/low-risk portion.
    *   Let's look at the "Volatility tables" in the Regulated Utilities section vs Unregulated.
    *   The "Unregulated Power and Gas" section states: "We use the medial volatility table only when assessing companies that derive a significant proportion of their operating cash flow... from regulated activities... or strongly protected unregulated revenue."
    *   The "Regulated Utilities" section is typically for companies where the *primary* driver is regulation.
    *   Given the dominance of electricity sales revenue (merchant/exposed) over grid revenue, VERBUND is often classified as **Unregulated Power and Gas** or a hybrid. However, for the purpose of this exercise, we must check if the "Regulated Utilities" methodology provides specific adjustments that differ significantly from the baseline. The baseline formula for Adjusted EBITDA is standard. The key difference in Utilities is often the treatment of debt-like items (purchased power contracts) or regulatory assets.
    *   Let's look at the data. We have EBITDA directly reported. We have Interest Expense. We have Tax. We have Debt figures.
    *   The prompt asks to estimate S&P's credit trend. S&P rates VERBUND. In reality, S&P considers VERBUND's business risk profile as "Strong" or "Strong/Adequate" due to its low-cost hydro portfolio and regulated grid, often applying the **Regulated Utilities** methodology or a modified Unregulated one with low volatility.
    *   Let's check the specific instructions: "If the entity does not fit into any of the provided industry methodologies, apply the general corporate baseline formulas."
    *   VERBUND fits into **Unregulated Power And Gas** (due to merchant generation) or **Regulated Utilities** (due to grid/hydro stability). The "Regulated Utilities" methodology mentions: "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." VERBUND is a net exporter/generator, not primarily a distributor meeting native load via third parties in the same way a US IOU might.
    *   Most importantly, the calculation of Adjusted EBITDA, FFO, and Adjusted Debt follows the baseline formulas unless specific industry adjustments (like lease capitalization or pension deficits) are required. The provided data does not explicitly detail lease liabilities separate from the balance sheet lines (though "Right-of-use Assets" are present, implying IFRS 16 adoption, so reported EBITDA likely already includes lease add-backs or needs checking). Under IFRS, EBITDA is usually reported after lease interest/depreciation? No, IFRS 16 usually results in EBITDA being higher than under operating lease accounting because rent expense is replaced by depreciation and interest. S&P typically adds back lease interest to FFO? No, S&P defines FFO as EBITDA - Cash Interest - Cash Taxes. If EBITDA is IFRS reported, it includes the lease benefit. S&P often adjusts Debt to include lease liabilities.
    *   Let's assume the **Unregulated Power and Gas** or **General Corporate** baseline is appropriate for the *calculation mechanics* as no complex "purchased power" debt adjustment data is provided (only aggregate "Expenses for Electricity Grid Gas..."). We will stick to the baseline formulas provided in the prompt steps, incorporating standard S&P adjustments where data allows (e.g., adding lease liabilities to debt).

    *   **Decision**: We will use the baseline formulas. For "Adjusted Debt", we must include lease liabilities if they are debt-like. The balance sheet shows "Right-of-use Assets" and implicitly lease liabilities within "Noncurrent Financial Liabilities" or "Current Financial Liabilities" or a separate line? The data lists "Noncurrent Financial Liabilities" and "Current Financial Liabilities". It does not explicitly break out "Lease Liabilities". However, under IFRS, these are often part of financial liabilities. We will use the reported Financial Liabilities as the base for Debt. S&P also deducts eligible cash.

**Step 2: Estimate 2021 Adjusted_EBITDA**

*   **Reported EBITDA (2021)**: 1,578,959,000 EUR
*   **Adjustments**:
    *   *Leases*: The prompt doesn't give explicit lease expense/add-back data. Under IFRS 16, EBITDA is generally already "adjusted" for operating leases (rent is removed, depreciation/interest added back to EBITDA? No, rent is an operating expense. IFRS 16 moves rent to Depreciation and Interest. So EBITDA increases by the amount of rent previously deducted. S&P typically treats the lease liability as debt. We don't need to adjust EBITDA for leases if it's already IFRS 16 compliant, which VERBUND is.
    *   *Nonrecurring items*: The data shows "Impairment Loss" (9,869,000) and "Reversal of Impairment Loss" (115,009,000). Impairment losses are typically non-cash and added back to EBITDA? No, EBITDA is Earnings Before Interest, Taxes, Depreciation, and Amortization. Impairment is usually below EBITDA or included in "Other Expense by Nature"?
        *   Let's check the reconstruction:
        *   Profit from Operating Activities (2021): 1,266,830,000
        *   Add: Depreciation (417,269,000)
        *   Add: Impairment Loss (9,869,000) - Wait, impairment is an expense. If it's included in Operating Profit, it was deducted. EBITDA usually adds back impairment? S&P definition: EBITDA + Non-recurring losses - Non-recurring gains.
        *   The reported EBITDA is 1,578,959,000.
        *   Let's verify: 1,266,830,000 (Op Profit) + 417,269,000 (D&A) = 1,684,099,000.
        *   The reported EBITDA is 1,578,959,000. The difference is ~105M.
        *   There is a "Reversal of Impairment Loss" of 115,009,000. This is a gain.
        *   There is "Valuation and Realisation of Energy derivatives" of -269,667,000. This is a loss/expense? Or income? The sign is negative. In the context of "Other Income" being positive, this might be an expense or a negative income.
        *   Usually, S&P starts with Reported EBITDA and adjusts for non-recurring items.
        *   Impairment reversals are often considered non-recurring gains and subtracted. Impairment losses are added back.
        *   Net Impairment impact: Loss 9.8M, Reversal 115M. Net Gain ~105M.
        *   If Reported EBITDA includes the reversal gain, we should subtract it.
        *   However, without a clear breakdown of what is inside the reported EBITDA line item regarding these specific non-operating/other items, and given the prompt asks to use the baseline formula `Adjusted_EBITDA = EBITDA + ...`, we will assume the reported EBITDA is the starting point.
        *   Are there significant non-recurring items? The impairment reversal (115M) is significant. S&P typically normalizes earnings. A reversal of impairment is a non-cash gain that inflates EBITDA/Operating Profit. We should likely subtract this non-recurring gain.
        *   Let's look at 2022: Impairment Loss 197M, Reversal 125M. Net Loss ~72M.
        *   For 2021: Net Gain ~105M.
        *   Adjustment: Subtract 115,009,000 (Reversal) and Add 9,869,000 (Loss)? Or just net?
        *   Let's assume the Reported EBITDA figure provided (1,578,959,000) is the standard management EBITDA. S&P adjustments usually focus on debt-like items and structural adjustments. For simplicity and lacking specific "non-recurring" tags in the data, we will use the Reported EBITDA as the base, but note that S&P might normalize the impairment reversal.
        *   *Self-Correction*: The prompt provides a specific formula: `Adjusted_EBITDA = EBITDA + adjustment_leases + nonrecurring_losses - nonrecurring_gains`.
        *   Nonrecurring Gain: Reversal of Impairment Loss (115,009,000).
        *   Nonrecurring Loss: Impairment Loss (9,869,000).
        *   Adjusted EBITDA 2021 = 1,578,959,000 + 9,869,000 - 115,009,000 = 1,473,819,000 EUR.
        *   *Alternative View*: Often, impairment and reversals are excluded from "Core" EBITDA by analysts. Let's apply this normalization.
        *   Also, "Valuation and Realisation of Energy derivatives" (-269,667,000). This is likely a mark-to-market loss/gain on hedging. For utilities, this can be volatile. Is it non-recurring? It's part of trading operations. S&P might include it if it's part of core operations. Given VERBUND is a trader, this might be core. We will leave it in.
        *   So, **2021 Adjusted EBITDA** ≈ 1,473,819,000 EUR.

    *   *Refinement*: Let's look at the magnitude. 115M is ~7% of EBITDA. It's material.
    *   Let's check 2022 similarly.
    *   Reported EBITDA 2022: 3,160,679,000.
    *   Impairment Loss: 197,761,000.
    *   Reversal: 125,973,000.
    *   Net Impairment Expense: 71,788,000.
    *   Adjustment: Add Loss (197,761,000) - Subtract Reversal (125,973,000) = Net Add 71,788,000.
    *   **2022 Adjusted EBITDA** = 3,160,679,000 + 71,788,000 = 3,232,467,000 EUR.

    *   *Note on Leases*: The balance sheet shows Right-of-Use Assets. IFRS 16 EBITDA is generally higher than old GAAP. S&P adds lease liabilities to Debt. It does not typically adjust EBITDA further for leases if IFRS 16 is used, as the rent expense is already gone from EBITDA.

**Step 3: Estimate 2021 FFO**

*   Formula: `FFO = Adjusted_EBITDA - cash_interest - cash_taxes`
*   **Adjusted EBITDA (2021)**: 1,473,819,000 EUR
*   **Cash Interest**:
    *   Reported Interest Expense: 77,814,000 EUR.
    *   The Cash Flow statement shows "Interest Paid Classified As Operating Activities": 17,900,000 EUR.
    *   S&P uses *cash* interest paid.
    *   Cash Interest 2021 = 17,900,000 EUR.
*   **Cash Taxes**:
    *   Reported Income Tax Expense: 279,365,000 EUR.
    *   Cash Flow statement shows "Income Taxes Paid Classified As Operating Activities": 238,200,000 EUR.
    *   Cash Taxes 2021 = 238,200,000 EUR.
*   **FFO 2021** = 1,473,819,000 - 17,900,000 - 238,200,000 = **1,217,719,000 EUR**.

**Step 4: Estimate 2021 Adjusted_Debt**

*   Formula: `Adjusted_Debt = (reported_debt + leases + pension_deficit + guarantees + hybrid_debt_portion + other_debt_like_items) - eligible_cash`
*   **Reported Debt**:
    *   Noncurrent Financial Liabilities: 1,202,154,000 EUR.
    *   Current Financial Liabilities: 84,056,000 EUR.
    *   Total Financial Debt = 1,286,210,000 EUR.
*   **Leases**:
    *   The data does not explicitly list "Lease Liabilities". However, "Right-of-use Assets" are 110,663,000 (2021 start) / 103,826,000 (2022 start).
    *   Usually, Lease Liabilities are close to ROU Assets. We should check if they are included in "Financial Liabilities". In many IFRS reports, lease liabilities are part of financial liabilities. If they are separate, we need to add them. If they are included, we don't.
    *   Looking at the magnitude, ROU is ~100M. Total Debt is ~1.28B.
    *   Without a specific "Lease Liabilities" line, and knowing IFRS 16 often bundles them or lists them separately, let's look for clues. "Noncurrent Financial Liabilities" is 1.2B. "Current Financial Liabilities" is 84M.
    *   If we assume the reported "Financial Liabilities" *exclude* leases (common in some summaries unless specified), we should add them. However, standard IFRS balance sheets often have a separate line for "Lease Liabilities". Here, we only have "Financial Liabilities". It is safer to assume "Financial Liabilities" captures interest-bearing debt. Leases are interest-bearing.
    *   Let's check the Cash Flow: "Payments Of Lease Liabilities Classified As Financing Activities" is 27,523,000 EUR. This confirms lease liabilities exist and are treated as financing.
    *   Are they in the "Financial Liabilities" line? If not, we must add them.
    *   Estimate of Lease Liabilities: Often similar to ROU. Let's estimate ~100,000,000 EUR.
    *   However, if we look at S&P methodology, they add *unadjusted* lease liabilities if not in debt.
    *   Let's assume the conservative approach: Add Lease Liabilities. We can approximate them using the ROU asset value or the payment flow. A rough proxy for the liability is the ROU asset value: ~104,000,000 EUR (using 2022-01-01 balance for 2021 year-end? No, 2021-01-01 is start of 2021. End of 2021 is 2022-01-01).
    *   So, Lease Liabilities (End 2021) ≈ ROU Assets (2022-01-01) = 103,826,000 EUR.
    *   Let's add this to Debt.
*   **Pension Deficit**:
    *   "Other Comprehensive Income... Remeasurements of Defined Benefit Plans" shows gains/losses.
    *   We don't have the explicit Net Pension Liability on the balance sheet.
    *   However, "Noncurrent Provisions" is 886,219,000. This often includes pensions.
    *   S&P adjusts for the *underfunded* portion. Without the plan asset value, we can't calculate the deficit precisely.
    *   However, the OCI impact is relatively small (86M gain in 2021).
    *   We will assume the pension deficit is either included in provisions (which are not debt) or is not material enough to drastically change the trend without specific data. We will omit specific pension debt adjustment due to lack of data, or assume it's negligible relative to the large cash position.
*   **Eligible Cash**:
    *   Cash and Cash Equivalents (2022-01-01, i.e., End 2021): 318,562,000 EUR.
    *   S&P deducts unrestricted cash.
*   **Calculation**:
    *   Debt: 1,286,210,000 (Financial Liabilities)
    *   Add Leases: 103,826,000 (Estimated from ROU)
    *   Gross Adjusted Debt: 1,390,036,000 EUR.
    *   Less Cash: 318,562,000 EUR.
    *   **Adjusted Debt 2021** = 1,390,036,000 - 318,562,000 = **1,071,474,000 EUR**.

    *   *Alternative*: If "Financial Liabilities" already includes leases, then Debt is 1,286,210,000. Net Debt = 1,286,210,000 - 318,562,000 = 967,648,000.
    *   Let's check the trend. The absolute amount matters less than the change if the classification is consistent.
    *   Let's stick to the explicit "Financial Liabilities" + "Lease Liabilities" if separate. Since they aren't explicitly separated in the liability lines, but "Payments of Lease Liabilities" exists in CF, it's highly likely they are part of Financial Liabilities or a subset. In many European reports, "Financial Liabilities" is the catch-all for interest-bearing debt including leases. If we assume they are *included*, we don't add them. If we assume they are *excluded*, we add them.
    *   Given the ROU asset is small (~100M) compared to Debt (~1.3B), the error margin is small.
    *   Let's assume **Financial Liabilities** represents the total interest-bearing debt (including leases).
    *   **Adjusted Debt 2021** = 1,286,210,000 - 318,562,000 = **967,648,000 EUR**.

**Step 5: Calculate 2021 Adjusted_Debt / Adjusted_EBITDA**

*   Ratio = 967,648,000 / 1,473,819,000 = **0.66x**

**Step 6: Calculate 2021 FFO / Adjusted_Debt**

*   Ratio = 1,217,719,000 / 967,648,000 = **1.26x** (or 126%)

**Step 7: Estimate 2022 Adjusted_EBITDA**

*   Reported EBITDA (2022): 3,160,679,000 EUR.
*   Adjustments:
    *   Add Impairment Loss: 197,761,000 EUR.
    *   Subtract Reversal of Impairment: 125,973,000 EUR.
    *   Net Adjustment: +71,788,000 EUR.
*   **Adjusted EBITDA 2022** = 3,160,679,000 + 71,788,000 = **3,232,467,000 EUR**.

**Step 8: Estimate 2022 FFO**

*   Formula: `FFO = Adjusted_EBITDA - cash_interest - cash_taxes`
*   **Cash Interest**:
    *   Interest Paid (2022): 36,100,000 EUR.
*   **Cash Taxes**:
    *   Income Taxes Paid (2022): 343,100,000 EUR.
*   **FFO 2022** = 3,232,467,000 - 36,100,000 - 343,100,000 = **2,853,267,000 EUR**.

**Step 9: Estimate 2022 Adjusted_Debt**

*   **Reported Debt**:
    *   Noncurrent Financial Liabilities (2023-01-01, i.e., End 2022): 2,844,559,000 EUR.
    *   Current Financial Liabilities (2023-01-01): 1,109,297,000 EUR.
    *   Total Financial Debt = 3,953,856,000 EUR.
*   **Leases**:
    *   ROU Assets (End 2022 / 2023-01-01): 146,613,000 EUR.
    *   Assuming included in Financial Liabilities (consistent with 2021 assumption).
*   **Eligible Cash**:
    *   Cash and Cash Equivalents (End 2022): 409,252,000 EUR.
*   **Adjusted Debt 2022** = 3,953,856,000 - 409,252,000 = **3,544,604,000 EUR**.

    *   *Note*: Debt increased significantly from ~1.28B to ~3.95B. This is a large increase.
    *   Why? "Noncurrent Financial Liabilities" went from 1.2B to 2.8B. "Current" from 84M to 1.1B.
    *   This indicates significant borrowing or reclassification.

**Step 10: Calculate 2022 Adjusted_Debt / Adjusted_EBITDA**

*   Ratio = 3,544,604,000 / 3,232,467,000 = **1.10x**

**Step 11: Calculate 2022 FFO / Adjusted_Debt**

*   Ratio = 2,853,267,000 / 3,544,604,000 = **0.80x** (or 80%)

**Step 12: Classify the credit trend**

*   **Signal 1: Leverage (Debt/EBITDA)**
    *   2021: 0.66x
    *   2022: 1.10x
    *   Change: 1.10 - 0.66 = **+0.44x**
    *   Threshold: ≥ +0.2x is **Deteriorating**.

*   **Signal 2: Cash-flow coverage (FFO/Debt)**
    *   2021: 1.26x
    *   2022: 0.80x
    *   Change: 0.80 - 1.26 = **-0.46x**
    *   Threshold: ≤ -0.03 is **Deteriorating**.

*   **Combination**:
    *   Signal 1: Deteriorating
    *   Signal 2: Deteriorating
    *   Both signals agree.

**Conclusion**: The credit trend is Deteriorating.

The primary driver is the significant increase in debt (from ~0.97B net to ~3.54B net), which outpaced the growth in EBITDA (from ~1.47B to ~3.23B). While EBITDA more than doubled, Debt nearly quadrupled, leading to higher leverage and lower coverage.
