Sources and calculations

Financial inputs from company filings. Last checked Oct 18, 2026. A dash means missing inputs or an undefined calculation.

Period changes use the preceding fiscal quarter or year. Percentage changes divide by the absolute prior value; a zero or missing baseline has no percentage change. Percentage metrics show changes in percentage points.

The SBC option subtracts reported share-based compensation from FCF as an economic-cost scenario. Missing SBC never becomes zero.

Debt uses reported borrowings, with overlapping concepts treated as alternatives. Cash excludes restricted cash and short-term investments. Dilution compares split-normalized weighted average basic shares year over year. Share buyback spending does not by itself measure shares retired.

Total debt: Reported borrowing balances. Uses an aggregate including current maturities, or current plus noncurrent debt. Adds separately disclosed short-term borrowings, with commercial paper as a fallback, unless the selected current/aggregate concept already includes them. Finance leases are included when part of the reported debt concept; undisclosed components are not estimated.
Cash & equivalents: Unrestricted reported cash and cash equivalents. Excludes short-term investments and restricted cash.
Net debt: Total debt − cash and equivalents. Negative means net cash.
Debt / equity: Total debt / equity including noncontrolling interests. Nonpositive equity yields unavailable.
Debt / assets: Total debt / total assets × 100.
Net debt / EBITDA: Period-end net debt / (TTM operating income + TTM depreciation and amortization). Negative net debt is retained.
Debt / FCF: Period-end reported debt / positive TTM free cash flow. Reflects the selected reported capex scope and SBC option.
Interest coverage: TTM operating income / positive TTM interest expense. IFRS finance costs can include more than interest.
Current ratio: Current assets / positive current liabilities.
Diluted shares: Reported weighted average diluted shares, normalized for subsequent recorded stock splits. Fourth-quarter counts use a day-weighted annual/nine-month reconstruction where possible.
Basic shares: Reported weighted average basic shares, normalized for subsequent recorded stock splits.
Share count growth: Year-over-year change in split-normalized weighted average basic shares × 100. A dilution proxy; negative means a lower share count.
Share repurchases: Reported cash payments for repurchase of common shares. This is spending, not a buyback yield.
