leader in Nigeria's inevitable energy expansion FACTORS INCREASING NIGERIA'S DEMAND FOR ENERGY > The population will more than double by 2050 - - (200m to 450m by 2050) > Access to energy will increase - 60% today, with target of 100% by 2030 > Per-capita consumption will increase - Less than 150kwh/year today, vs global average of 2,674 kwh/year > Increasing national wealth will drive new consumption through economic development - e.g. air conditioning, refrigeration, EVs > Multiplier effects will boost energy demand > Nigeria's massive gas reserves will support this growth in electricity demand > Gas is the ideal transition fuel on the way to renewable energy Mű 嗨 Demand for reliable electricity increases Businesses and households increase energy usage Increase gas supply

year $109 million spent in 9M 2020 SEPLAT PETROLEUM DEVELOPMENT COMPANY PLC | INVESTOR PRESENTATION SHORT TERM VALUE DRIVERS (0-2 YEARS) 1. New gas wells expected to increase gas production in 2021 (75MMscfd gross) 2. Increase in production from Eland's OML40/Ubima fields, with exports not dependent on Seplat's existing export routes 3. Greater and more reliable output expected from OMLS 4,38, and 41 as Amukpe-Escravos pipeline assures more secure flow, reduces losses through shut-ins and vandalism 4. Potential for dedicated export route to support OML 40 and OML 4,38,41, reducing handling costs and reconciliation losses 5. Improved uptime from increased focus on operational improvements in 2020; increased field development 6. Prioritise prolific swamp wells to increase production 7. Sapele gas plant will reduce flaring, monetise gas LONGER TERM VALUE DRIVERS (2+ YEARS) 1. Significant opportunity from gas displacement of diesel generators as government prioritises gas-fired electricity 2. ANOH significantly boosts potential income from gas from 2022, further decoupling value from oil price volatility; expansion potential beyond 300MMscfd to serve increasing demand 3. Opportunity to increase scale of oil and gas businesses through M&A as IOCs divest Nigerian assets 4. $400m+ cash flows expected from Westport loan repayments 5. Significant reserve upgrade potential from Eland's Amobe prospect at OML40, benefiting from Eland expertise#54AC 54 SEPLAT PETROLEUM DEVELOPMENT COMPANY PLC | INVESTOR PRESENTATION APPENDIX www.seplatpetroleum.com se#55QUARTERLY PERFORMANCE 9M RESULTS SHOW CONTINUING RECOVERY FROM TWIN CRISES $ million FINANCIAL Q1 2020 Q2 2020 Q3 2020 9M 2020 9M 2019 Revenue EBIT 130.5 103.0 154.2 388.8 494.9 (77.0) (35.8) 33.5 (79.3) 211.2 PBT (95.7) (49.6) 15.3 (130.1) 184.8 Realised oil price ($/bbl) 50.09 25.69 42.65 38.60 64.20 Realised gas price ($/Mscf) 2.89 2.88 2.88 2.88 2.80 Cash at bank 336.0 342.6 213.0 213.0 333.0 (FY 2019) OPERATIONAL Oil (bopd) 33,368 35,372 31,764 33,327 23,658 Gas (MMscfd) 88 110 104 100 136 Total working interest (boepd) 48,491 54,369 49,617 50,653 47,163 SAFETY Fatalities LTI 0 0 7 7 0 0 0 0 0 0 55 SEPLAT PETROLEUM DEVELOPMENT COMPANY PLC | INVESTOR PRESENTATION#56seplat Head Office Seplat Plc 16A, Temple Road, Ikoyi, Lagos, Nigeria. +234 (0)1 277 0400 [email protected] www.seplatpetroleum.com London Office Seplat UK Ltd. 4th Floor, 50 Pall Mall, London SW1Y 5JH +44 (0)20 3725 6500 Investor Relations [email protected] [email protected]
