Placement capacity

How much stock a company can place without asking holders. Listing Rule 7.1 allows 15% of ordinary securities in any 12 months, and every Appendix 3B states how much of it an issue uses.

About 72% of the 15% placement capacity left — about 28% used by Appendix 3B filings in the last 12 months (estimate, as at 2026-09-12). The company has also placed under the additional 10% (Listing Rule 7.1A), which is not counted in this figure. Holder-approved issues and any later ratification are not deducted, so the true headroom can be higher.

“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.

1 class ceased in the last 12 months and is not counted above
The company’s own Appendix 2A restates each of these at zero. They are excluded from the overhang, the in-the-money supply and every figure on this page. Each count is the filing’s own count of securities in the class, not a share count — a 2A never states what one security converts into.
