Ithaca Energy plc ("Ithaca Energy" or the "Company")

Exclusivity Agreement for a potential transformational combination with Eni S.p.A.'s UK Business

Ithaca Energy, a leading independent oil and gas operator in the UK North Sea, today announces that it has entered into an exclusivity agreement (the "Exclusivity Agreement") in relation to a potential transformational combination with substantially all of Eni S.p.A.'s ("Eni") UK upstream assets including the recently acquired Neptune Energy assets, excluding certain assets including Eni's CCUS and Irish sea assets (the "Potential Combination").

Pursuant to the Exclusivity Agreement, Eni has granted Ithaca Energy exclusivity in respect of the assets, the subject of the Potential Combination, for a period of 4 weeks from the date of this announcement. Ithaca Energy and Eni have entered into the Exclusivity Agreement to allow time to separately progress the contractual documentation required in connection with the Potential Combination.

Key highlights of the Potential Combination

Ithaca Energy anticipates that the Potential Combination will require shareholder approval as a Class 1 transaction. Additionally, as Eni will hold between 38% and 39% of the voting rights of Ithaca Energy at completion of the Potential Combination, a mandatory offer would normally be required under Rule 9 of the UK Code on Takeovers and Mergers (the "Takeover Code"). However, given that Delek will still hold shares carrying more than 50% of the voting rights following completion of the Potential Combination, the UK Panel on Takeover and Mergers (the "Panel") have granted a dispensation from Rule 9 pursuant to note 5 (b) of Rule 9 under the Takeover Code. Accordingly, completion of the Potential Combination will not be conditional upon and will not require approval by Ithaca Energy's independent shareholders in relation to a Rule 9 waiver.

Although the discussions are at an advanced stage, there can be no certainty that a Potential Combination will occur, nor as to the final terms or timing on which a Potential Combination might be concluded.

Further announcements will be made if and when appropriate.

The information contained within this announcement is deemed by Ithaca Energy to constitute inside information for the purposes of Article 7 of the Market Abuse Regulation (EU) No 596/2014 (as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018). By the publication of this announcement via a Regulatory Information Service, this inside information is now considered to be in the public domain.  The person responsible for making this announcement on behalf of Ithaca Energy is Julie McAteer, General Counsel and Company Secretary.

About Ithaca Energy plc

Ithaca Energy is a leading UK independent exploration and production company focused on the UK North Sea with a strong track record of material value creation.

Today, Ithaca Energy is one of the largest independent oil and gas companies in the United Kingdom Continental Shelf (the "UKCS"), ranking second by resources.

With stakes in six of the ten largest fields in the UKCS and two of UKCS's largest pre-development fields, and with energy security currently being a key focus of the UK Government, the Group believes it can utilise its significant reserves and operational capabilities to play a key role in delivering security of domestic energy supply from the UKCS.
