What the market is pricing
Wide range: intrinsic value is highly sensitive to assumptions — use the scenario analysis to anchor your view.
Valuation range
Red = below today's price. Green = above.
ISRG fair value — three scenarios
At today's price of $451.38, start with the base case.
Downside — if growth disappoints
Use this if growth slows, margins stay weak, or investors demand more return.
Most likely outcome
Start here unless you have a strong reason to disagree with the base case.
Upside — if execution beats expectations
Use this if the company grows faster or earns more than the base case assumes.
DCF key assumptions
These three inputs drive most of the intrinsic value estimate. If your view of the business differs on any of them, adjust the scenario above — the fair value will shift accordingly.
Revenue growth forecast
Fades to 5.5% in years 6-10
The model already fades growth below reported 5Y CAGR.
Operating margin forecast
Current operating margin (TTM): 30.5%
The model holds margins near the current run-rate — no heroic profitability improvement required.
WACC (required return)
Terminal growth 2.8% | Spread 6.2 pts
The 6.2 pts gap between required return and long-run growth is reasonable, but the model will still react to rate changes.
All DCF inputs
High-impact inputs are the ones most likely to change the intrinsic value estimate if you disagree.
Revenue growth (years 1-5)
Average annual revenue growth assumed across the first five forecast years.
Revenue growth (years 6-10)
Growth gradually fades toward a long-run sustainable rate in the second forecast decade.
Operating margin (year 1 → year 10)
Profitability path used to convert revenue into free cash flow across the forecast period.
CapEx & reinvestment
How much of operating profit is spent on CapEx and working capital instead of being distributed as free cash flow.
WACC — weighted average cost of capital
Built from beta 1.01, risk-free rate, and equity risk premium. A higher WACC compresses intrinsic value quickly.
Terminal growth rate
Perpetual growth rate applied after year 10 — sets the size of the terminal value that drives most of the DCF.
Free cash flows to the firm discounted at WACC (enterprise model). Forecast source: analyst estimates. If your view of the business differs on any of these inputs, the bear and bull scenarios above show how the fair value shifts.

Cash flow measure: Operating margin
The first decade contributes real value, but the terminal value still accounts for the majority of Intuitive Surgical, Inc.'s DCF estimate.
In the base case, 39% of intrinsic value comes from the 10-year forecast and 61% from the terminal value. The higher the terminal value share, the more the fair value depends on long-run growth assumptions rather than near-term execution.

Cash flow path

Year 1 to Year 10 base case
The base case asks for a meaningful ramp in free cash flow over the decade.

How the score is calculated
Model limitations
Terminal value is notable
-6 ptsAbout 60-70% of the DCF depends on what happens after Year 10, so the model is less anchored in near-term execution.
Limited data coverage
-2 ptsSome inputs could not be fully verified from available sources, so the estimate carries a wider margin of uncertainty.
Model strengths
Sufficient operating history
✓ PassAt least five years of annual history feed the model, so the forecast is not starting from a thin base.
Analyst-backed revenue forecast
✓ PassRevenue and margin assumptions are based on analyst estimates, not just historical trends.
DCF sensitivity analysis
Small changes in WACC or terminal growth can shift the intrinsic value estimate significantly. This table tests whether Intuitive Surgical, Inc. still looks undervalued, fairly priced, or overvalued when those assumptions are adjusted up or down.
WACC × terminal growth
Each cell tests a different WACC and terminal growth combination. Top-left is the harshest. Bottom-right is the most forgiving.

What to do with this
Most tested scenarios still show Intuitive Surgical, Inc. trading above intrinsic value. To change this reading you would need to believe WACC should be materially lower or long-run growth materially higher than the base case — the scenario cards above let you test both directly.
Reverse DCF — what today's price implies
Reverse DCF keeps the cash-flow forecast fixed — including about 12.9% average revenue growth in Years 1–5 — then asks: what required return or long-run growth rate would make today's price rational?
Price vs. DCF fair value
above DCF fair value
What today's price is asking you to believe
Both required return and long-run growth need to be more favorable than the base case.
The stock trades 118% above the DCF fair-value estimate — the other side of the 54% premium shown in the verdict above (both measure the same gap, just from different reference points). The market is effectively assuming a lower required return, a higher long-run growth rate, or both.

Holding the required return fixed, this price only works if long-run growth is 6.8% — above the 2.8% rate in the base case. That pushes long-run growth into a range investors should treat cautiously for a mature US business.
