Is DexCom under- or over-valued?
Valuing a stock is incredibly difficult, and any metric has to be viewed as part of a bigger picture of overall performance. However, analysts commonly use some key metrics to help gauge value. Check out the DexCom P/E ratio, PEG ratio and EBITDA.
DexCom's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 41x. In other words, DexCom's shares trade at around 41x recent earnings.
That's relatively high compared to, say, the trailing 12-month P/E ratio for the United States stock markets on average as of March 2025 (25.37). The high P/E ratio could mean that investors are optimistic about the outlook for the shares or simply that they're over-valued.
DexCom's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 1.0755. A PEG ratio close to 1 can be interpreted as meaning shares offer reasonable value for the current rate of growth.
The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into DexCom's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.
DexCom's EBITDA (earnings before interest, taxes, depreciation and amortisation) is a whopping $1 billion (£748.1 million).
The EBITDA is a measure of DexCom's overall financial performance and is widely used to measure a its profitability.
