Options & convertible securities
- Price-triggered1.44B · 19.8% of sharesOptions and warrants — they convert when the share price clears their exercise price.
- Condition-triggered125.0M · 1.7% of sharesPerformance and incentive rights — they convert when a hurdle is met, not at a price, and can lapse to nothing.
Exercise price on record: 1.44B priced (of which 1.44B in the money), 125.0M where the filing never states one. A security with no exercise price is never counted in the money — nothing is paid to convert it, so there is no price for it to be above.
Each figure is the filing’s own count of securities, not a share count — a 2A never states what one security converts into.
At $0.0010 today, 1.44B securities are in the money (19.8% of shares on issue). No price up to ten times today’s switches on any more priced supply.
- Priced supply in the money at the price on the axis — the curve, and the only thing on it. Ten prices, sampled: between two of them the true figure lies between the two.
- 125.0M (8.0% of the supply above) states no exercise price at all. It cannot be called in or out of the money at any price, which is why it is hatched rather than plotted.

“Nil” is a stated nil exercise price: nothing is paid to convert. An em dash means the filing names no exercise price at all. Security is read from the filing’s own class description; an em dash there means the description is not one this table labels. One row is one security class, at the number stated in the most recent quotation application that restated it — linked, and dated, in the last column. For what expires soon across other listed companies, see the options expiry calendar.
A condition-triggered class has no exercise price and usually no expiry: what it vests on is set by a shareholder resolution, not by the register. Where the company lodged a notice of meeting before the class first appears here, it is linked as “Meeting” — that is where terms of this kind are put to shareholders. It is not confirmation that the document sets this class’s conditions, and no link appears where there is no such filing.
