Completion of Shortfall Bookbuild

Genesis Energy Limited (“Genesis”) is pleased to announce the successful completion of the shortfall bookbuild component of its NZ$300 million underwritten 1 for 7.9 pro rata renounceable rights offer (“Rights Offer”). The clearing price under the shortfall bookbuild was NZ$2.22 per new share, representing a premium of NZ$0.17 to the application price of NZ$2.05 per new share under the Rights Offer. Therefore, eligible shareholders who did not take up their rights in full and shareholders who were ineligible to participate in the Rights Offer will receive NZ$0.17 for each new share not taken up by them. Ineligible shareholders will be deemed to hold the number of rights they would have received if they were eligible shareholders for the purpose of calculating the amount of the premium. Payment of the premium is expected to be made on 31 March 2026. Settlement of the Rights Offer is expected to occur on 24 March 2026 for the ASX and on 25 March 2026 for the NZX, with allotment and commencement of trading on NZX and ASX expected to occur on 25 March 2026. The new shares issued under the Rights Offer will rank equally with Genesis’ existing shares. A total of approximately NZ$400 million was raised in aggregate across the Rights Offer and the NZ$100 million underwritten placement (“Placement”) announced by Genesis on 23 February 2026. For further information in respect of the Placement and Rights Offer, please refer to the equity raise presentation and Offer Document released to the NZX and ASX on 23 February 2026.
