Definitions and reading notes
Fiscal years follow the company’s filings and may differ from calendar years. Quarterly values cover a single fiscal quarter. The latest reported quarter here means the latest quarter in the checked SEC snapshot; more recent announcements may not yet be included.
Free cash flow = operating cash flow + signed capital expenditure (a cash outflow is negative). Operating margin = operating income ÷ revenue × 100. These are calculated metrics. Figures derived from year-to-date differences, fourth-quarter subtraction or component arithmetic are also marked Calculated. Display values are rounded; calculations use stored unrounded values.
Unavailable means the stored SEC release has no value. It is not treated as zero. Growth percentages are omitted when the prior value is zero or negative. No currency conversion, estimates or trailing-twelve-month figures are used.
