Its assumptions

Powerpack lets you start from a scenario and type over any of them.

The base case’s inputs, which Powerpack lets you change
1 · Cash flow to equity
the four quarters to September 2026, from the 10-Q and 10-K filings, before share-based pay

Yearly growth in cash flow. It usually slows as the company matures.

Today’s price implies free cash flow after share-based pay growing 26.9% a year for ten years.

2 · Rates

Cost of equity is the yearly return shareholders require, typically 8–11%. Terminal growth is growth forever after year 10, usually near long-run inflation, 2–3%.

3 · Per share

Diluted shares outstanding. Net debt, under Advanced inputs, is taken off before dividing.

Every growth rate on this page is the business’s — its cash flow, FFO or dividend — never its share price’s. A discounted-cash-flow model is only as good as its assumptions. Figures from the 10-K and 10-Q filings. Not investment advice.
