• One new Jubilee well (J72-P) brought onstream in July 2025, which is currently producing c.8 kbopd.
• Average FPSO uptime at Jubilee and TEN of 97%.

2026 FIRST QUARTER PERFORMANCE

• Group working interest oil and gas production averaged 43.4 kboepd during the first quarter of 2026, underpinning expectations of delivering the higher end of full year guidance.
• The Petroleum Agreement extensions to 2040 for the Jubilee and TEN fields were ratified by the Ghanaian parliament in February 2026, unlocking the potential to book further material oil and gas reserves.
• Tullow secured revised terms for the supply of gas from the Jubilee field to the end of the extended period at an escalating price of $2.50/mmbtu and agreed heads of terms for the potential supply of gas from the TEN fields.
• Tullow and the Government of Ghana have also agreed a gas payment security.
• 2025-26 Ghana drilling programme continues with J74-P onstream in January 2026 and J75-P onstream in March 2026.
• On 19 February 2026, Tullow signed a Sale and Purchase Agreement to acquire the TEN FPSO on behalf of the joint venture for a gross consideration of $205 million ($125.6 million net to Tullow), which is to be paid upon completion at the end of the first quarter of 2027. Following completion Tullow intends to maximise operational synergies with the adjacent Jubilee Field and drive further cost efficiencies which will underpin the longer-term development of the TEN and Jubilee fields.

2026 OUTLOOK AND GUIDANCE

• Group working interest production is expected to be at the higher end of the previously announced 34-42, including c.6 kboepd of gas.
• A further four Jubilee wells are expected onstream before the end of the year (three producers and one water injector).
• Capital expenditure2 of c.$200 million, allocated as follows: c.$190 million in Ghana and c.$10 million in Côte d’Ivoire.
• Decommissioning spend of c.$5 million for UK; c.$20 million cash provisioning for Ghana.
• Commodity hedge portfolio protecting c.60% of 2026 forecast sales volumes whilst retaining material oil price upside exposure.
• Pre-financing cash flow2 guidance has increased to c.$260-365 million at $70-100/bbl, primarily due to year to date production performance being above expectations, higher oil price realisations and the higher oil price assumption used for guidance.
• Free cash flow guidance of $70-175 million at $70-100/bbl.
• Cash flow would increase by c.$40 million from $70/bbl to $80/bbl and then by a further c.$30 million for every additional $10/bbl increase, non-linear due to hedges in place.
• Free cash flow guidance includes recovery of 2025 cash call receivables and c.$40 million gas revenues related to 2026 gas production, but excludes c.$110 million historical gas receivables and the c.$50 million receivable related to TEN development debt. Following execution of the Master Gas Agreement, Tullow has a payment security mechanism for gas. Tullow is working closely with the Government of Ghana and its agencies to resolve the historic receivables on a mutually acceptable basis.
• Interpretation of 4D and OBN seismic data ongoing to support well design and placement in the current drill programme and unlock future reserves growth in the Jubilee and TEN fields.
• On 27 April 2026, Tullow completed a comprehensive refinancing transaction, which includes an extension to its Senior Secured Notes and Glencore facility to November 2028 and May 2030 respectively, and a new $100 million cargo pre-payment facility with Glencore to provide additional liquidity. The transaction provides a stable platform for Tullow to deliver its investment programme and realise the full value of its assets.
• Following completion of the comprenhensive refinancing transaction, Tullow has liquidity headroom of free cash and undrawn facilities in excess of $200 million.
