What Growth Is Priced In

Implied revenue growth (10Y)

9.4%

incredible deal

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%
