On October 8, 2024, pursuant to the Agreement and Plan of Merger, dated July 21, 2024, by and among Woodside Energy Holdings (NA) LLC, a Delaware limited liability company (“Parent”), and Woodside Energy (Transitory) Inc., a Delaware corporation (“Merger Sub”), and the Registrant, Merger Sub merged with and into the Registrant (the “Merger”), with the Registrant continuing as the surviving corporation of the Merger and a wholly owned subsidiary of Parent. These Post-Effective Amendments are being filed as a result of the Merger.

The Registrant, by filing these Post-Effective Amendments, hereby terminates the effectiveness of the Registration Statements and removes from registration any and all shares of Common Stock registered but unsold or otherwise unissued under the Registration Statements as of the date hereof. This filing is made in accordance with an undertaking made by the Registrant in Part II of each Registration Statement to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offering.
