5-year outlook: Not shown because confidence is low: Earnings-based DCF is somewhat apart.
Other models: USD 653.09–1027.83 (median 824.83). The recommended value is 31% above that median, so treat the upside with extra caution.
Why: Free cash flow is positive and in line with earnings, and the dividend is small, so a cash-flow DCF fits best.
Details and the full model are below.
Market price within modeled range
Free-cash-flow DCF using a three-year average of free cash flow, because the latest figure is depressed by heavy investment or one-off items, with cash, debt, and shares from the latest report. Base assumptions are 22.68% growth, 2.7% terminal growth, and 10% discount. Low/high cases vary growth by 2 and terminal growth/discount by 1 percentage point; this illustrative range is not a statistical confidence interval or investment advice.
Assumptions: growth 22.68%, discount rate 10%, terminal growth 2.70% (sector defaults). See a worked example.
Blended growth assumption: 22.7% (sector default 6.2%, own revenue history 31.2%, analyst revenue consensus 26.7%).
Analyst consensus expects revenue growth of 26.7% a year; the growth assumption used is 22.7%.
Adjust assumptions
Why this model: Free cash flow is positive and in line with earnings, and the dividend is small, so a cash-flow DCF fits best.

EPS-based Gordon proxy
— USD 653.09 (-32.3%)
Not used: Treats all earnings as if paid out and ignores the cash kept for reinvestment, so it overstates value for companies that retain most profit.
-
DCF (trailing free cash flow)
— USD 2224.15 (+130.5%)
Not used: Not chosen: Free-cash-flow DCF ranks ahead of it for this company.

FCFF (steady state)
— USD 1027.83 (+6.5%)
Not used: Assumes only the long-run terminal growth rate from today, so it ignores the near-term growth expected.
-
EV/EBITDA (12x)
— USD 824.83 (-14.5%)
Not used: Used only when free cash flow is far below earnings even after averaging three years; a fixed 12x multiple also ignores sector differences.
-
Fade DCF (10-year growth fade)
— USD 2203.37 (+128.3%)
Not used: An alternative growth path (fading over 10 years) shown for comparison; the automatic choice does not use it.

Margin = (value − price) / value, so it is measured against the value and reads lower than the upside to value, which is measured against the price. Positive means the price is below that case.
At USD 964.94 the market implies about this annual free-cash-flow growth for 5 years (terminal 2.7%, discount 10.0%).
Compare: the market implies 19.5% a year, this model assumes 22.7%. The model is more optimistic than the price, which is why it reads as undervalued.
