Q1 2024 Strategic Highlights

Transformative Business Combination with Eni UK

·    Announced transformational Business Combination of Ithaca Energy and substantially all of Eni S.p.A's (Eni) UK upstream oil and gas assets in April 2024, creating a UK powerhouse that provides the strategic platform for long-term growth in the UK North Sea and internationally through the combination of complementary portfolios.

-     UKCS powerhouse with estimated pro-forma 2024 production of 100,000 - 110,000 barrels of oil equivalent per day²

-     Agility of an Independent and capability of a Major, implementing Eni's successful regional satellite model

-     Complementary portfolio unlocks potential for material long-term organic growth with the capability to increase the Combined Group's production to over 150,000 barrels of oil equivalent per day by the early 2030s on an un-risked basis³

-     Platform for further inorganic growth in the UK and internationally

-     Highly cash-generative combination providing material dividend capacity with ambition for up to $500 million total dividends each year in 2024 and 2025⁴

·    Following completion of the Business Combination, Eni will be a fully committed, long-term and supportive shareholder of the combined business

-     Based on the merger ratio, Ithaca Energy's shareholders will own 61.5% and Eni will own 38.5% of the combined entity

-     Sell down provisions have been put in place, together with an Eni Call option, to maintain a free float of 10% on completion

BUILD

·    Rosebank development project progressing as planned to multi-year development timeline:

-     Petrojarl Rosebank FPSO docked in Dubai with vessel upgrade work continuing

-     Q1 preparation work ahead of commencement of Subsea, Umbilicals, Risers and Flowlines (SURF) activity in Q2

·    Successfully awarded license extension from 31 March 2024 to 31 March 2026 for Cambo field on 19 March, supporting the ongoing farm-in process to enable the future progression of Cambo and Fotla towards FID, subject to fiscal and market conditions

·    Continued progression of Captain Electrification FEED study to support FID in due course, subject to fiscal and market conditions

BOOST

·    Captain continues to deliver against a high-activity plan in support of the Enhanced Oil Recovery (EOR) Phase II project now substantially complete and in preparation for turnaround activity in May. During the quarter, rig recertification was successfully executed on plan and on budget in support of the topside drilling campaign scheduled for Q3

·    Final verification activities completed supporting milestone first EOR Phase II polymer injection into the subsea wells during H1 2024, with the following activities completed in the Q1:

-        Drilling: Completed drilling operations of remaining three Area D polymer injection wells and new production well B35 brought online

-        Subsea: Completed installation of all remaining subsea infrastructure including flowlines, umbilicals, subsea distribution units to enable EOR II start-up

-        Facilities: Successfully completed significant facilities maintenance scopes across power generation, gas compression and oil export pumps

·    Preparation for W1 well workover at Erskine during Q2, reinstating a fifth production well at the field

Q1 2024 Operational Update

·    Q1 production of 58.7 thousand barrels of oil equivalent per day (kboe/d), supporting full year pro-forma 2024 production guidance issued 23 April

·    Q1 production split 69% liquids, 31% gas

·    Q1 production reflects previously guided operational issues across our non-operated joint venture portfolio:

-     Non-operated Pierce field production impacted as the vessel remained off stream for the entirety of Q1. The issue has now been resolved and field production is ramping up

-     Non-operated Schiehallion field production impacted by weather related downtime and outages caused by the Ocean Great White rig being off station, which will also impact the timing of production wells later in 2024

-     Compressor issues at Erskine's host facility (Lomond) impacting production in Q1
