Biogen cash flow and EPS—

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.

FCF subtracts reported cash capital investment. PPE purchases are preferred; the productive-assets fallback also includes software and intangibles. Acquisitions and noncash lease additions are excluded. EPS and weighted shares are not summed across quarters. Annual figures use annual reports.

SBC / FCF always uses FCF before SBC deduction; both SBC ratios compare amounts from the same period. A zero or negative cash-flow denominator is undefined, and values above 100% are retained.

Each reported nonnegative cash use / sum of available tracked nonnegative cash uses × 100. Missing categories are omitted, never set to zero. This is the composition of tracked uses, not a complete cash-flow reconciliation or a percentage of OCF. SBC is noncash and excluded. Negative amounts are excluded as reversals or net receipts; they are not converted to spending. Annual bars use reported annual amounts. Turning off a category hides its share without changing the denominator. Debt repayments prefer a reported aggregate, with long-term or convertible-only scope identified in the tooltip. Acquisitions are net of cash acquired. Dividend payments use the aggregate where reported, including dividend equivalents when part of that concept.

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

Operating cash flow

Reported net cash provided by or used in operating activities.

Capital expenditures

Reported cash capital investment. Uses purchases of property, plant and equipment where disclosed; otherwise purchases of productive assets, which can also include software and intangibles. Excludes acquisitions and noncash lease additions.

Free cash flow

Operating cash flow − reported cash capital investment. PPE purchases are preferred; the productive-assets fallback also includes software and intangibles. Reflects the SBC option and can differ from issuer-defined FCF.

Stock-based compensation

Reported share-based compensation addback in the cash-flow statement. Missing disclosure is not treated as zero.

SBC / free cash flow

Reported share-based compensation / (operating cash flow − cash capital investment) × 100, for the same fiscal period. Always uses FCF before SBC deduction. Zero or negative FCF is undefined; values above 100% are retained.

SBC / operating cash flow

Reported share-based compensation / reported operating cash flow × 100, for the same fiscal period. Zero or negative operating cash flow is undefined. Unaffected by the SBC deduction scenario.

Software & intangible investment

Separately tagged payments for capitalized software under US GAAP, or purchases of intangible assets under IFRS. This optional disclosure is not inferred from total capex or deducted a second time from FCF.

Diluted EPS

Reported diluted earnings per share, normalized for recorded subsequent stock splits. Quarterly EPS is never subtracted from annual or YTD EPS.
