Ann: Yancoal debt prepayment of US$459 million, page-14

So net cash at the end of December will be around $2.7 billion, assuming $2 billion in cash generation in last quarter. This will be made up of AU$3.2 billion cash and AU$500 million in debt
Market cap currently $7.6 billion so EV = AU$4.9 billion.

Over last 15 months they have paid $5.5 billion in debt and dividends:
AU$4.1 billion in debt
AU$1.4 billion in dividends (2H2021 + 1H2022)

It is not totally unrealistic that the current share price will be returned to shareholders in the next 15 months via 3 dividends (2H2022, 1H2023 and 2H2023). The final dividend tends to be much larger, and we have two of those in the next 15 months.

The commencement of tax payments could get in the way of this, but if so, then the dividends will come with franking credits.
