The ASX300 rebalancing rules are a little bit of a dark art.

To avoid excessive churn of companies on the margin, companies that have made it into the ASX300 can keep their spot for a while even if they fall below the 300th position. This tolerance appears to have an element of judgement and includes factors like market liquidity. This means there is a reasonable number of companies above the 300th point that are not part of the ASX300 and are waiting for a company in the index to be taken over or for S&P to decide to remove one of the participants that have had a collapsing share price. Inclusion is not hit #300 and get in.

Unless EGR issues an excessively large number of new shares, it will be a great day for all current shareholders if EGR does get into the genuine inclusion space but its a long way away at present.
