Change of Company Name

Cairn plans to change its company name from Cairn Energy PLC to Capricorn Energy PLC, effective from 13 December 2021. The LSE stock ticker will remain as CNE.

This follows an agreement at the time of the Cairn India IPO that the name would ultimately be changed.

Given the recent legislative change in India and our participation in the related tax refund process, we are now putting in place the planned name change.

The new name reflects continuity and evolution: the majority of Cairn's subsidiaries have been known as Capricorn for some time. It is an established and respected name across our global operations, maintaining stakeholder confidence in our long-standing reputation for responsibility, relationships and respect.

No action from shareholders is required in relation to the change.
