Ann: Quarterly Activities/Appendix 5B Cash Flow Report, page-31

Unfortunately it is not that simple. It is impossible to safely predict the future share price. But on the other hand there are some formulas which may be of help to estimate (!) the future share price.

The following formular may help you, which calculates the P/E ratio.
The price-to-earnings ratio (P/E) is the ratio of a company's share price to the company's earnings per share (EPS)

P/E Ratio = Price per share / EPS

A typical P/E for coal miners is 7 (but with a great spread, for example from 4-15). But let us calculate with 7. On the basis of your example the company would be valued 2 USD x 7 = 14 USD, and not (!) 2 USD.

Very popular is the Discounted Cash Flow (DCF) method, which estimates the value of an investment using its expected future cash flows. For example it is used in the Patersons Research Note from 2019. The report values the company as follows: MC A$359M, or approx. 71c (AUD) per share.
