Hi MessDog - the PE ratio is the price/earnings ratio. It can be calculated by dividing the share price by the earnings per share in the financial results. It is often used as a guideline to compare profitable companies within the same industry, on the assumption that all companies should demand a similar market value based on a certain profit.
For example, if BMN has a market cap of £400m and is making an annual profit after tax of £80m, the P/E ratio would be 5. This could then be compared to other companies in the mining sector to see whether a P/E ratio of 5 is low, high, or about right. I believe profitable miners on the AIM currently have an average P/E of around 11, so one could suggest that perhaps for a profit of £80m, fair value for BMN should be £880m.
For technology companies, particularly disruptive ones with huge potential for growth, you would expect the P/E ratio to be much higher. That's why Bushveld Energy is particularly exciting, and why a lot of us here are very excited at the potential scale of that side of the business.
