Step 1: Identify the relevant industry Based on the description "transmission system operator" and being wholly owned by the Dutch State, TenneT Holding B.V. operates as a Regulated Utility (specifically Electricity National). Step 2: Estimate 2021 Adjusted_EBITDA Formula: Adjusted_EBITDA = EBITDA + adjustment_leases + nonrecurring_losses - nonrecurring_gains ± pension_adjustments ± joint_venture_proportional_EBITDA ± other_normalization_adjustments 2021 EBITDA = Revenue (5,524) - Employee Benefits (287) - Misc. Operating Expense (303) - Other Gains Losses (-4) = 4,938 million EUR. Lease adjustment: 8x Rent = 8 * (Right-of-use assets change + Depreciation). RoU change = 433 - (254-254+0 approx baseline) -> assume ~54m. Depreciation roughly 235/5 ~ 47m. Rent ~ 101m. Adjustment ~ 808m. (Will use a simpler standard approximation for S&P: Rent = Lease interest + Lease depreciation. Finance costs include ~50m lease interest. Lease exp ~ 50+47 = ~97m. Adj = 8*97 = 776m. Let's just use the standard x8 multiplier on estimated rent. Rent approx 100m -> Adj 800m. Net Income = -340m. Tax = -135m. EBT = -475m. EBITDA = EBT + D&A (1,165) + Net Interest (200) = 890m. Wait, let's recalculate accurately. EBITDA = Operating Profit (-275) + D&A (1,165) + Other losses (4) = 894 million EUR. Rent = Lease interest (~25m from 202/156 diff) + Lease depreciation (~47m). Total Rent ~ 72m. Adjustment = 8 * 72 = 576 million EUR. Adjusted EBITDA (2021) = 894 + 576 = 1,470 million EUR. Step 3: Estimate 2021 FFO Formula: FFO = Adjusted_EBITDA - cash_interest - cash_taxes Cash Interest = Interest paid (174) + Lease interest (~25) = 199 million EUR. Cash Taxes = Income taxes paid (246) million EUR. FFO (2021) = 1,470 - 199 - 246 = 1,025 million 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 = Long-term Borrowings (12,366) + Short-term Borrowings (1,339) + Current Bank Overdrafts (64) = 13,769 million EUR. Leases = Noncurrent Lease Liabilities (235) + Current Lease Liabilities (169) = 404 million EUR. Pension deficit = Noncurrent DB Liabilities (351) + Current DB Liabilities (0) - DB Assets (0) = 351 million EUR. Hybrid Debt = Hybrid Capital (2,125) treated as 100% debt under S&P utilities criteria until called. Other debt-like = Other Noncurrent Financial Liabilities (183) + Other Current Financial Liabilities (281) = 464 million EUR. Gross Debt = 13,769 + 404 + 351 + 2,125 + 464 = 17,113 million EUR. Eligible Cash = Cash (3,204). (S&P typically allows 100% cash for utilities due to rating exclusion). Adjusted Debt (2021) = 17,113 - 3,204 = 13,909 million EUR. Step 5: Calculate 2021 Adjusted_Debt / Adjusted_EBITDA Ratio (2021) = 13,909 / 1,470 = 9.46x. Step 6: Calculate 2021 FFO / Adjusted_Debt Ratio (2021) = 1,025 / 13,909 = 7.37% (0.0737). Step 7: Estimate 2022 Adjusted_EBITDA 2022 EBITDA = Operating Profit (-976) + D&A (1,233) + Other losses (38) = 295 million EUR. Rent = Lease interest (~100m from 300/202 diff) + Lease depreciation (~81m). Total Rent ~ 181m. Adjustment = 8 * 181 = 1,448 million EUR. Adjusted EBITDA (2022) = 295 + 1,448 = 1,743 million EUR. Step 8: Estimate 2022 FFO Cash Interest = Interest paid (202) + Lease interest (~100) = 302 million EUR. Cash Taxes = Income taxes paid (231) million EUR. FFO (2022) = 1,743 - 302 - 231 = 1,210 million EUR. Step 9: Estimate 2022 Adjusted_Debt Reported Debt = Long-term Borrowings (19,006) + Short-term Borrowings (709) + Current Bank Overdrafts (0) = 19,715 million EUR. Leases = Noncurrent Lease Liabilities (574) + Current Lease Liabilities (155) = 729 million EUR. Pension deficit = Noncurrent DB Liabilities (174) = 174 million EUR. Hybrid Debt = Hybrid Capital (2,125) million EUR. Other debt-like = Other Noncurrent Financial Liabilities (185) + Other Current Financial Liabilities (550) = 735 million EUR. Gross Debt = 19,715 + 729 + 174 + 2,125 + 735 = 23,478 million EUR. Eligible Cash = Cash (6,547). Adjusted Debt (2022) = 23,478 - 6,547 = 16,931 million EUR. Step 10: Calculate 2022 Adjusted_Debt / Adjusted_EBITDA Ratio (2022) = 16,931 / 1,743 = 9.71x. Step 11: Calculate 2022 FFO / Adjusted_Debt Ratio (2022) = 1,210 / 16,931 = 7.15% (0.0715). Step 12: Classify the year-on-year credit trend Signal 1: Leverage. Change in Adjusted_Debt / Adjusted_EBITDA = 9.71x - 9.46x = +0.25x. Thresholds: ≤ -0.2x (Improving), between -0.2x and +0.2x (Stable), ≥ +0.2x (Deteriorating). Result: +0.25x ≥ +0.2x -> Deteriorating. Signal 2: Cash-flow coverage. Change in FFO / Adjusted_Debt = 0.0715 - 0.0737 = -0.0022. Thresholds: ≥ +0.03 (Improving), between -0.03 and +0.03 (Stable), ≤ -0.03 (Deteriorating). Result: -0.0022 is between -0.03 and +0.03 -> Stable. Combining the two signals: One signal is Deteriorating, the other is Stable. Following the rule "If one is Stable and the other is Improving or Deteriorating, return the non-Stable category," the final classification is Deteriorating. Deteriorating
