What Growth Is Priced In
Implied revenue growth (10Y)
9.4%
The annual FCF growth rate today's price requires over a 10-year horizon (discount rate 10%, terminal growth 2.5%).
Dilution drag: 1.1% — per-share value needs a total required return of 10.5% once share-count change is priced in.
vs. own 6-year median revenue growth: 18.7%

Earnings bubble check
Current margins may be above sustainable levels — a P/E based on peak earnings can overstate cheapness.
Revenue growth and the path to profitability (margin trend) are the primary reads at this stage.
