Step 1: Identify the relevant industry for IBERDROLA SA. Based on its annual report, Iberdrola is a diversified utility with significant operations in electricity networks, renewable energy generation, and power purchase agreements (PPAs). Its activities span regulated networks (electricity distribution and transmission) and unregulated generation (renewables). According to the S&P methodology, this aligns with "Unregulated Power and Gas" (given the large renewable portfolio and generation focus, though parts are regulated) or "Regulated Utilities". Given the presence of both, and the description of "Unregulated Power and Gas" methodology for renewable generation companies that benefit from policy support and long-term contracts, Iberdrola's competitive advantage is assessed under "Unregulated Power and Gas" methodology. However, S&P applies the methodology based on the predominant mix. For the calculation of adjusted debt and EBITDA, the baseline formulas are consistent, with industry-specific adjustments often related to purchased power obligations, pension deficits, securitized debt, leases, and asset retirement obligations. Step 2: Estimate the "Adjusted_Debt". Baseline formula: Adjusted_Debt = (reported_debt + leases + pension_deficit + guarantees + hybrid_debt_portion + other_debt_like_items) - eligible_cash. From the balance sheet as of 2023-01-01 (which is Dec 31, 2022): Reported debt components: - Noncurrent Financial Liabilities: €44,216,000,000 - Current Financial Liabilities: €25,079,000,000 - Cash and Cash Equivalents: €4,608,000,000 - Current Financial Assets: €4,813,000,000 (may include derivatives and other items, only cash and cash equivalents are deducted) - Pension deficit: Noncurrent Provisions for Employee Benefits: €1,226,000,000; Current Provisions for Employee Benefits: €42,000,000. Total pension provisions = €1,268,000,000. Underfunded pension is debt-like. - Leases: Noncurrent Lease Liabilities: €2,287,000,000; Current Lease Liabilities: €151,000,000. Total lease liabilities = €2,438,000,000. - Hybrid debt portion: Instruments de Capital con Caracteristicas de Pasivo Financiero No Corriente: €576,000,000; Current: €87,000,000. S&P typically treats 50% of hybrid instruments as debt. Total hybrid = €663,000,000. Hybrid debt portion = 50% * 663,000,000 = €331,500,000. - Other debt-like items: Noncurrent Provisions (other than employee benefits): €2,999,000,000; Current Provisions: €922,000,000 - €42,000,000 (employee benefits current) = €880,000,000. These may be considered debt-like depending on nature. Asset retirement obligations and environmental provisions are debt-like. Total other provisions = €2,999,000,000 + €880,000,000 = €3,879,000,000. For simplicity, we include all non-employee provisions. - Current Derivative Financial Liabilities and Noncurrent Derivative Financial Liabilities are part of reported financial liabilities, so already included. - Guarantees: not explicitly listed, assume 0. - Eligible cash: Cash and Cash Equivalents = €4,608,000,000. Adjusted_Debt = (44,216,000,000 + 25,079,000,000) [reported financial debt] + 2,438,000,000 [leases] + 1,268,000,000 [pension deficit] + 0 [guarantees] + 331,500,000 [hybrid debt portion] + 3,879,000,000 [other debt-like provisions] - 4,608,000,000 [eligible cash] Total reported financial debt = 69,295,000,000. Adjusted_Debt = 69,295,000,000 + 2,438,000,000 + 1,268,000,000 + 331,500,000 + 3,879,000,000 - 4,608,000,000 = 72,603,500,000. Step 3: Estimate the "Adjusted_EBITDA". Reported "Beneficio Bruto De Explotacion Ebitda" (EBITDA) for 2022-01-01 to 2023-01-01: €13,228,000,000. Adjustments: - Leases: S&P adds back lease depreciation and lease interest to EBITDA. However, the reported EBITDA likely already includes the operating lease expense (as IFRS 16 was adopted, depreciation and interest are separated). S&P adjusts by adding back the lease-related expense and deducting lease-related depreciation. A simpler proxy is to add the lease expense (principal + interest) or compute adjusted EBITDA with 8x rent expense. Given IFRS 16, leases are capitalized, so EBITDA already excludes rent expense (replaced by depreciation and interest). S&P often adds back lease depreciation and lease interest to get to EBITDAR. For simplicity, we can use EBITDA + lease expense. But without the exact split, we approximate: lease liabilities are €2,438,000,000; typical S&P adjustment for leases is to add back the current year lease expense. Noncurrent Lease Liabilities €2,287,000,000, Current €151,000,000. We can estimate lease expense from the cash flow statement: "Pago De Principal De Pasivos Financieros Por Arrendamiento" = -175,000,000 and "Intereses Pagados Excluidos Intereses Capitalizados De Pasivos Financieros Por Arrendamiento" = -61,000,000. Total lease payment = €236,000,000. This is a cash flow, not accrual; EBITDA is accrual-based. We'll assume lease expense is roughly €236,000,000. Added to EBITDA. - Non-recurring items: "Other Gains Losses" = €911,000,000 (includes gains on sale, impairments? The text says "Other Gains Losses", could include non-recurring items). Without further detail, we assume €0 adjustment, or we could subtract if it's a gain. But typically, "Other Gains Losses" in Iberdrola's context is part of operating. We'll keep as is. - Pension adjustments: The income statement shows no explicit pension cost, but "Employee Benefits Expense" includes pension service cost. The S&P adjustment is to add back service cost and subtract actual contributions, or use the pension deficit change. Without data, we assume it's included in EBITDA and no further adjustments. - Joint venture proportional EBITDA: "Share Of Other Comprehensive Income Of Associates And Joint Ventures Accounted For Using Equity Method" = €146,000,000 (income), but this is net income. EBITDA from associates is not separately given. We assume 0. - Non-recurring losses: "Profit Loss From Discontinued Operations" = -€71,000,000. This is below operating profit. For Adjusted EBITDA, we typically exclude discontinued operations. EBITDA from continuing operations is €13,228,000,000. No adjustment needed for discontinued ops as it's excluded from EBITDA. - Other normalization: none. Adjusted_EBITDA = 13,228,000,000 + 236,000,000 (lease expense) = €13,464,000,000. If S&P uses 8x rent for pre-IFRS 16, but since IFRS 16 is applied, they add back the depreciation and interest. The lease payment is €236,000,000, so Adjusted EBITDA = 13,228,000,000 + 236,000,000 = 13,464,000,000. Step 4: Calculate the "Adjusted_Debt / Adjusted_EBITDA" ratio. Adjusted_Debt = 72,603,500,000 Adjusted_EBITDA = 13,464,000,000 Ratio = 72,603,500,000 / 13,464,000,000 ≈ 5.392 Rounding to two decimal places: 5.39 Final answer: 5.39
