London Stock Exchange welcomes Ithaca Energy into the FTSE 100

The London Stock Exchange today welcomes Ithaca Energy plc for a market close to celebrate the Company's recent entry into the FTSE 100.

Ithaca Energy joined the FTSE 100 effective 21 September 2026, less than four years after listing on the London Stock Exchange. The milestone marks an important moment in the Company's journey and reflects the significant growth of the business since its London listing.

Ithaca Energy is one of the largest oil and gas operators in the UK Continental Shelf by resources and production. The Company has a balanced and diversified portfolio of over 30 producing fields, including interests in six of the ten largest fields in the UKCS, alongside a significant portfolio of development opportunities. In 2025, Ithaca Energy delivered average production of 119 kboe/d and had 657 mmboe of 2P reserves plus 2C resources as of 31 December 2025.

The Company's strategy is focused on delivering long-term value through optimising its producing portfolio, unlocking its organic growth opportunities, pursuing value-accretive M&A and focused international expansion. In October 2026, the Company announced its first international acquisition, purchasing a package of assets in Offshore East Coast, and marking a new era of growth for the Company.

Ithaca Energy is closing the market to celebrate its inclusion in the FTSE 100. The occasion recognises the continued development of the business and the contribution of its people across its onshore and offshore operations.

"Joining the FTSE 100 is an important milestone for Ithaca Energy and a moment that allows us to reflect on how far we have come.

Since listing in London less than four years ago, we have remained focused on running a great business: operating safely, reliably and with discipline, investing in our people and assets, and pursuing a clear strategy for growth.

Our entry into the FTSE 100 is testament to what we have built together and, above all, to the hard work, expertise and commitment of our people. As we celebrate this milestone at the London Stock Exchange, our focus remains firmly on the future and continuing to build a stronger, more resilient business that creates long-term value for all our stakeholders."
