Is Atlantic Power 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 Atlantic Power P/E ratio, PEG ratio and EBITDA.
Atlantic Power's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 7x. In other words, Atlantic Power's shares trade at around 7x recent earnings.
That's relatively low 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 low P/E ratio could mean that investors are pessimistic about the outlook for the shares or simply that they're under-valued.
Atlantic Power's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 0.68. A PEG ratio below 1 can be interpreted as meaning the shares are not overvalued given the current rate of growth.
The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into Atlantic Power's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.
Atlantic Power's EBITDA (earnings before interest, taxes, depreciation and amortisation) is $87.9 million (£65.6 million).
The EBITDA is a measure of Atlantic Power's overall financial performance and is widely used to measure a its profitability.
