ROIC surged from -9.72% to 6.01% over seven years while market expectations imply only 6.09% growth.

DexCom's 6.09% market-implied growth exceeds its 4.2% actual growth, yet the expectations gap may be justified by the company's transformation from growth to profitability optimization.

THE LENSES
THE EXPECTATIONS GAPreasonable

What expectations are embedded in the price, and are they reasonable?

Reverse DCF implies 6.09% perpetual growth vs 4.2% actual growth in Q4'25
TTM revenue growth of 15.6% decelerating sharply to 4.2% in latest quarter
Market prices at 24x earnings despite deceleration, suggesting growth re-acceleration expected
Stock trades at 21.27% of 52-week high despite record ROIC of 6.01%

This framework sees the market pricing in growth acceleration from current 4.2% to 6.09% perpetual, which exceeds current performance but remains below historical 15.6% TTM rate. The 66.3% price decline suggests expectations have already reset significantly, creating a moderate positive gap.

ROIC VS COST OF CAPITALimproving

Is the business creating or destroying value?

ROIC reached all-time high of 6.01% in Q4'25 vs WACC of 10.69%
Negative spread of -4.68% but narrowing from -10.68% in prior years
Seven-year transformation from -9.72% ROIC in Q4'18 to current levels
Operating margin expanded to record 25.6% in Q4'25

Applying this lens reveals DexCom still destroys value with ROIC below WACC, but the trajectory is exceptional - from massive destruction to near break-even. The framework recognizes this dramatic improvement trend matters more than the current negative spread.

ROIC vs Cost of Capital
COMPETITIVE ADVANTAGE PERIODdurable

How long can the company earn returns above its cost of capital?

Gross margins stable at 63.5% in Q4'25, up from 59.4% year-over-year
Operating margins expanded 640 basis points to record 25.6%
Revenue correlation with CPI of 0.981 demonstrates pricing power
94.6% institutional ownership with 48.7 year average holding period

This framework identifies strong evidence of a lengthening CAP - expanding margins, demonstrated pricing power, and long-term institutional commitment suggest sustainable advantages. The CGM device switching costs and healthcare necessity create durable moats.

Operating Margin
THE QUALITY OF GROWTHefficient

Is growth creating or destroying value?

Revenue growth decelerated from 15.6% TTM to 4.2% in Q4'25
Operating leverage coefficient of 7.99x amplifies margin expansion
Free cash flow generation of $1.08B TTM on slower growth
Reinvestment rate data insufficient for incremental ROIC calculation

The framework sees a fundamental shift - slower revenue growth producing higher cash flows and margins suggests value-creating efficiency gains. Operating leverage of 7.99x means each revenue point generates 8 points of profit growth, transforming modest growth into substantial value creation.

VERDICT

Applying the Mauboussin framework reveals a classic expectations recalibration opportunity. The market prices 6.09% growth for a business delivering 4.2%, yet this modest premium seems reasonable given the dramatic profitability transformation and lengthening competitive advantage period. The framework suggests the 66.3% drawdown has already reset expectations to achievable levels. Is the market still fighting the last war of growth deceleration while missing the new war of margin expansion?
