The CDI share purchase plan raised about A$17.42M (107,558,800 new CDIs at A$0.162), well short of the A$46M target. The US$32.0M PIPE (1,524,377 shares at US$21.00) still needs shareholder approval.
What it means for a shareholder
108m new shares at A$0.162 to raise about A$17.4m. That's 86% dilution: every existing holder's slice gets 86% smaller. If you held A$1,000 of shares (6,173 at the issue price), your slice goes from 0.0346% to 0.00492% of the company. To keep it you'd need 37,257 more shares - about A$6,036 at the issue price.
