ITHACA ENERGY PLC (the "GROUP")

Pricing of Senior Notes Offering and Upsize of RBL Facility

Transaction notification

Ithaca Energy plc ("Ithaca Energy") is pleased to announce that its wholly owned subsidiary Ithaca Energy (UK) Limited has secured commitments to exercise the accordion mechanism provided under its reserves based lending facility, which will increase the aggregate commitments under facility A from $1,000 million to $1,300 million, and that its wholly owned subsidiary Ithaca Energy  (North Sea) plc (the "Company") has priced its offering of an aggregate principal amount of €450,000,000 of 5.500% senior notes due 2031 (the "Notes") at par, with interest payable semi-annually.

A subsidiary of Ithaca Energy has entered into a currency swap in connection with the offering of the Notes, which will result in an all-in effective interest rate on the Notes, in USD, of approximately 6.7%. The Notes will be senior obligations of the Company and will be guaranteed on a senior basis by Ithaca Energy (E&P) Limited and on a senior subordinated basis by certain of Ithaca Energy's subsidiaries.

The gross proceeds from the offering of the Notes will be used: (i) to pay the purchase price of the Cygnus acquisition, (ii) for general corporate purposes (including to repay certain outstanding amounts under the reserves based lending facility and replenish cash used for the Japex M&A consideration), and (iii) to pay estimated transaction fees, expenses and other payments.

The closing of the offering is subject to customary conditions precedent for similar transactions.

Yaniv Friedman, Executive Chairman of Ithaca Energy, commented:

"Ithaca Energy is delighted to announce the successful pricing of its senior notes offering and the extension of its Reserves Based Lending facility. The significant investor demand and material oversubscription we saw in the market is testament to the strength and agility of our business and validates the Group's growth strategy, as we keep executing across all pillars of our strategy and delivering strong organic performance as well as further growth and returns to our shareholders. Importantly, this strategy is underpinned by maintaining financial discipline and flexibility, and this offering diversifies, further strengthens and optimises our financial position by extending our maturity profile and providing additional liquidity to pursue further growth opportunities."
