ASX participants and users were advised via market notice 0555.21.04 of ASX’s plan to trial the removal of Special Size crossings on NEW ETO Classes. The trial period for the removal of Special Size crossings for new ETO Classes proved successful and is now part of ASX’s ongoing ETO listing policy.

As part of the policy, ASX reviews how new ETO Classes are performing to determine if any have reached a liquidity metric that supports the introduction of Special Size crossings.

ASX has completed a review and determined that the introduction of Special Size crossings on one ETO Class is now appropriate. The introduction of Special Size on the ETO Class will occur on Monday, 2 February 2026.

The ETO Class whereby Special Size crossings will be introduced is:

-        VAU (Vault Minerals Ltd)
