To estimate the S&P-adjusted FFO-to-debt ratio for Ferrovial SA for 2022, we follow the prescribed workflow:

**Step 1: Identify Industry**
Ferrovial is a multinational infrastructure operator (toll roads, airports, and construction). Based on the methodology provided, "Transportation Infrastructure" is the most relevant industry classification.

**Step 2: Estimate Adjusted EBITDA**
*   Reported Profit from operations: 423,000,000 EUR
*   Add: Amortisation Expense: 299,000,000 EUR
*   Add: Impairment and gains/losses on disposal: 6,000,000 EUR (added back as loss)
*   Baseline EBITDA ≈ 423M + 299M + 6M = 728,000,000 EUR.
*   The facts state "Gross Profit" (including adjustments) of 728M. Using standard S&P adjustments (EBITDA = EBIT + D&A +/- adjustments), we use 728,000,000.

**Step 3: Estimate FFO**
*   FFO = Adjusted_EBITDA - cash_interest - cash_taxes
*   "Finance Income Cost" (adjusted for fair value): -320,000,000 EUR (total cost). "Interest Paid Classified As Financing Activities": 329,000,000 EUR. We use the cash interest paid: 329,000,000.
*   "Income Taxes Paid": 82,000,000 EUR.
*   FFO = 728,000,000 - 329,000,000 - 82,000,000 = 317,000,000 EUR.

**Step 4: Estimate Adjusted Debt**
*   Reported Debt:
    *   Noncurrent portion of other borrowings: 10,776,000,000
    *   Current borrowings: 877,000,000
    *   Noncurrent lease liabilities: 120,000,000
    *   Current lease liabilities: 64,000,000
*   Total Gross Debt: 10,776M + 877M + 120M + 64M = 11,837,000,000 EUR.
*   Eligible Cash: Cash and cash equivalents: 5,130,000,000 EUR.
*   Adjusted_Debt = 11,837,000,000 - 5,130,000,000 = 6,707,000,000 EUR.

**Step 5: Calculate FFO / Adjusted_Debt**
*   FFO / Adjusted_Debt = 317,000,000 / 6,707,000,000 ≈ 0.047264.

Rounding to four decimal places: 0.0473.
