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.
