Dividend forcast, page-29

for 6 months ending 31 January 2022 , NHC sold 5.138 Million tonnes of coal at an average price of A$192 per tonne , with an underlying FOB cost of A$87.57 giving a net margin of A$104 per tonne.

If NHC sold 5,100,000 tonnes in the second half at a net margin of $565 per tonne, gross revenue would be A$ 2,881,500,000.
(These assumptions are based on S32.ASX average sale figure for their last 6 months of A$652 per tonne less NHC's FOB cost per tonne of A$87.57)
For the first half NHC's PAT was about 33% of Revenue. Based on say 2.881 Billion , that suggests NPAT for 6months of about $1 Billion. (E&OE).
Using a 60% payout -the best prediction would be 72c dividend. But don't hold your breath.
