Administrative Form 4 reflecting cash-and-CVR merger terms.

The filing records a director’s disposition of 2,881 ESSA Pharma common shares due to a change of control. Consideration comprised cash of US$0.12 per share plus one CVR per share, consistent with the executed business combination.

CVRs provide contingent payments of up to US$0.14 per CVR, tied to post-closing milestones within specified periods. Proceeds flow to shareholders from the acquirer; issuer-level cash proceeds are not indicated here.

This is routine insider reporting of the merger’s mechanics rather than a standalone operating update. Actual holder outcomes depend on CVR milestone realizations as defined in the agreement.
