Each multiple at the closing price of the fiscal year's last trading day and the same year's figures. A year with a loss or negative free cash flow has no P/E or P/FCF. A P/E or P/FCF above 100 is left out: it comes from a year of near-zero earnings or cash flow and says little about the price.

How do I work out what SO is worth?

With the DCF calculator: it opens with Southern's figures from its filings, you enter your assumptions for growth and the return you ask for, and see the value they give. The company pages give no price target of their own. A full analysis gives a fair-value range, which is an estimate, not a target.
