1. Core Business Firing on All Cylinders
We can better understand Patient Monitoring companies by analyzing their organic revenue. This metric gives visibility into DexCom’s core business because it excludes one-time events such as mergers, acquisitions, and divestitures along with foreign currency fluctuations - non-fundamental factors that can manipulate the income statement.
Over the last two years, DexCom’s organic revenue averaged 19.2% year-on-year growth. This performance was fantastic and shows it can expand quickly without relying on expensive (and risky) acquisitions.
2. Outstanding Long-Term EPS Growth
We track the long-term change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.
DexCom’s EPS grew at an astounding 23.2% compounded annual growth rate over the last five years, higher than its 21% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

3. Stellar ROIC Showcases Lucrative Growth Opportunities
Growth gives us insight into a company’s long-term potential, but how capital-efficient was that growth? Enter ROIC, a metric showing how much operating profit a company generates relative to the money it has raised (debt and equity).
DexCom’s five-year average ROIC was 25%, placing it among the best healthcare companies. This illustrates its management team’s ability to invest in highly profitable ventures and produce tangible results for shareholders.
