2020 CAPITAL MARKETS DAY

Since December 2019, Tullow has taken significant steps to re-base its business through a major restructuring of its organisation and cost base which has led to substantial savings. This work has continued with the arrival of Rahul Dhir as CEO in July 2020 who has commissioned a comprehensive review of Tullow's portfolio, growth prospects and capital structure. Once this review is complete, and its conclusions have been fully validated, the Group will hold a Capital Markets Day (CMD) before the end of the year. At this CMD, Rahul Dhir and other senior leaders will lay out their plans for Tullow's business and assets and demonstrate how they will unlock material value from the portfolio.

2020 SECOND HALF OUTLOOK

  • Group production has been strong going into the second half and full year guidance has been narrowed to 73-77,000 bopd following good well performance in Ghana offset by the negative impact from OPEC+ quotas in Gabon
  • Maximising Jubilee/TEN gas offtake nominations; focus on continuous improvement to maintain FPSO uptime in excess of 95%
  • Ntomme-09production well came on stream in August and is incrementally adding c.5,000 bopd gross to TEN oil production

  • In Kenya, the JV has withdrawn its Force Majeure (FM) notice; the JV has received a 15-month licence extension; the farm-down process has been suspended pending a comprehensive review of the development concept and strategic alternatives
  • Capital and decommissioning expenditure full year guidance of c.$300 million and c.$65 million remains unchanged
  • 60 per cent of 2H 2020 sales revenue hedged with a floor of $57/bbl; 48 per cent of 2021 hedged with a floor of $51/bbl
  • 2020 free cash flow forecast to break even at the current forward curve subject to year-end working capital movements
  • Proceeds of $500 million from Uganda transaction completion expected before year-end; portfolio sales still targeted to deliver proceeds of over $1 billion in aggregate albeit in a challenging external environment for asset sales and farm downs
  • Organisational restructuring well advanced and forecast to deliver cash savings of over $350 million over three years, significantly in excess of the previous target of $200 million. This will deliver annual sustainable cash savings of over $125 million from 2021.
  • Semi-annualRBL debt capacity redetermination expected to complete in early October 2020; at Tullow's request, the next redetermination will be in January 2021 following the CMD later this year to incorporate the outcome of revised business plans
  • Evaluation of various refinancing alternatives with respect to the Group's capital structure is ongoing in parallel
  • New exploration acreage awarded in Peru; data reprocessing and evaluation continues in Guyana; drilling of Goliathberg- Voltzberg North well in Block 47, Suriname, planned for first quarter of 2021.

OPERATIONAL REVIEW

Production

Group working interest production averaged 77,700 bopd in the first half of 2020, in line with expectations. Full year guidance has been updated to reflect recent strong performance in Ghana, offset by production curtailments in Gabon due to OPEC+ quotas being applied. Overall, guidance for the full year is narrowed from 71-78,000 bopd to 73-77,000 bopd, with the mid-point forecast of 75,000 bopd maintained.

Ghana

The impact of COVID-19 has been managed safely across the business with no adverse impact on Ghana production. This has been achieved in close cooperation with the Government of Ghana.

Production across both fields in Ghana has been strong in the first half of 2020 with the Jubilee field averaging 84,700 bopd gross (net: 30,000 bopd) and the TEN field averaging 50,900 bopd gross (net: 24,000 bopd). This performance is a result of increased gas offtake nominations from the Ghana National Gas Company as well as approval from the Ministry of Energy to temporarily increase flaring, higher than forecast facility uptime of over 95% at both FPSOs and greater reliability and redundancy in the water injection facilities on the Jubilee FPSO.

At TEN, the Ntomme-09 production well came onstream at the start of August 2020 and is contributing an incremental c.5,000 bopd gross oil production. The Maersk Venturer drillship has now been released. Tenders are ongoing to contract a rig to recommence activity in Ghana in 2021.

The strong production performance has continued in the second half of the year with Jubilee and TEN averaging 90,000 bopd and 50,000 bopd gross respectively through July and August. This has been driven by continued high facility uptimes and strong well performance across both fields including the Ntomme-09 well that came onstream in early August.

The final phase of the Jubilee Turret Remediation Project is the installation of a Catenary Anchor Leg Mooring (CALM) buoy to assist with offloading. The CALM buoy arrived in Ghana in January 2020 however full installation works were delayed until September 2020. Once the installation works are complete, commissioning is expected to be completed in the fourth quarter of 2020.

A comprehensive review of the investment and production optimisation plans for Jubilee and TEN, which are designed to realise the full potential of both assets and to maximise value for all stakeholders, is currently under way. This review is being conducted in consultation with the Joint Venture Partners and is supported by expert advisors.

Non-operated portfolio

Production from Tullow's non-operated portfolio in the first half has been stable with working interest production averaging 23,700 bopd, in line with expectations.

Production performance across the non-operated portfolio is expected to remain stable in the second half of 2020. However, in August, Tullow received notification from the operator of the Simba field that as part of Gabon's requirement to comply with the OPEC+ quota, the field would be shut in until the end of the year. This is expected to have a net negative impact on average annual Group production of approximately 1,500 bopd which is incorporated in the revised production guidance. The final outcome is subject to change depending on how the Government of Gabon implement the quotas. Tullow are working closely with Joint Venture Partners to ensure any production curtailments are equitably shared.

Decommissioning

Decommissioning in Tullow-operated licences in the UK North Sea continues to progress as planned with final removal and seabed clearance activities scheduled from September 2020. In Mauritania, decommissioning of the wells in the Chinguetti field was suspended following the Government's decision to close the borders due to COVID-19 in March 2020.

Kenya

Tullow has been working with its Joint Venture Partners to progress the full field development plan. In May 2020 Tullow and its Joint Venture Partners declared FM on the Kenya licences. Following productive discussions with the Government, an improvement in the COVID-19 situation and assurances from Government that the tax incentives granted to the phased project will continue to apply, the FM notices were withdrawn in August 2020. Whilst these issues have resulted in a delay to the Final Investment Decision (FID) on the project, it has allowed time for both Tullow and its Joint Venture Partners to collaboratively work on realising the full potential of the assets. This has resulted in the Government of Kenya agreeing to an initial extension to the Second Additional Exploration Period for the 10BB and 13T licence blocks until 31 December 2020 with a final extension until 31 December 2021, contingent on an agreed work programme and budgets. Separately, the farm down process has been suspended while the Joint Venture Partners complete a comprehensive review of the development concept to ensure it continues to be robust at low oil prices, and also consider the strategic alternatives for the asset.

Uganda

Following the announcement on 23 April 2020 that Tullow had agreed the sale of its assets in Uganda to Total for $500 million in cash on completion, $75 million in cash following FID, plus post first oil contingent payments, the transaction is progressing as planned with completion expected before the year-end.

On 28 May 2020 CNOOC Uganda Limited informed both Tullow and Total that it had elected not to exercise its pre-emption rights.

On 18 June 2020 Tullow published the shareholder circular relating to the transaction and on 15 July 2020 a General Meeting was held, at which the transaction received approval with over 99 per cent of the 56 per cent votes cast in favour.

On 6 August 2020 the Government of Uganda provided their consent to the transfer of operatorship from Tullow to Total.

Completion of the transaction remains subject to the Government of Uganda and the Uganda Revenue Authority entering into a binding Tax Agreement with Tullow Uganda and Total Uganda that reflects the pre-agreed principles on the tax treatment of the transaction, and the Government of Uganda approving the transfer of Tullow's interests to Total. Good progress is being made in satisfying these conditions to completion.

Exploration

Tullow retains a high-quality exploration portfolio in both Africa and South America with high-potential opportunities. However, in light of the challenging external environment Tullow will be minimising exploration spend in the short term and looking at ways to rebalance the portfolio whilst maintaining opportunities to realise value and preserve longer term options for growth.

South America

In Suriname, the Goliathberg-Voltzberg North well in Block 47 is now planned to be drilled in the first quarter of 2021, testing dual targets in the Cretaceous turbidite play in approximately 1,900 metres of water. The well will be drilled by the Stena Forth drillship.

Data reprocessing and evaluation continues in Guyana to support future drilling activity. In Peru, Tullow has been awarded blocks Z67 and Z68 in the Trujillo basin, targeting a completely new petroleum system and new plays.

Seismic acquisition in Argentina commenced in the fourth quarter of 2019 and was able to continue until May 2020 before being put on hold due to the impact of the COVID-19 pandemic. Recommencement is targeted for the fourth quarter of 2020.

Tullow has now exited the Walton-Morant licence in Jamaica which expired on 31 July 2020.

Africa

Seismic acquisition in Côte d'Ivoire commenced in February 2020 but was suspended in April 2020 due to the impact of the COVID- 19 pandemic. The data collected during the early stages of the project is now being evaluated to decide on the next steps for the basin.

In Namibia, Tullow is awaiting the outcome of the Venus-1 well which is expected to be drilled by Total in the fourth quarter of 2020 on a block to the south of Tullow's PEL-90 acreage before deciding next steps.

SHAREHOLDER ENGAGEMENT

At the AGM on 23 April 2020, a significant number (33%) of votes were cast against Resolution 13. The Resolution sought the authority for Directors to make allotments of shares in accordance with routine practice in the UK and complied with the guidance published by the Investment Association and the Pre-Emption Group. Being an Ordinary Resolution, it was passed but the vote against was a clear statement from a few of our shareholders. Following the AGM, our Chair of the Board has engaged with our major shareholders who voted against the resolution and now has an understanding of the concerns raised by them. The concerns relate to the potential dilution of their existing shareholdings and the Board has noted these concerns.

Production and commodity prices

Total Group working interest production averaged 77,700 boepd (1H 2019: 86,300 boepd), a decrease of 10% for the period. The

realised oil price after hedging for the period was $51.8/bbl (1H 2019: $64.3/bbl) and before hedging $42.5/bbl (1H 2019: $66.7/bbl). The impact of COVID-19 pandemic on global oil demand resulted in significant discounts to the Dated Brent benchmark oil price for the cargoes sold during April and May 2020. Low oil prices led to a gain on the realisation of commodity hedges, increasing total revenue by $130.8 million (1H 2019: loss of $32.6 million).

Operating costs, depreciation and expenses

Underlying cash operating costs amounted to $155 million; $11.0/boe (1H 2019: $145 million; $9.0/boe). The increase in cash unit operating costs is principally due to both the ending of the Business Interruption coverage in May 2019, which offset exceptional operating costs for Jubilee such as shuttle tanker operation which will continue until completion of the CALM buoy offloading system as well as lower production for the period.

DD&A charges before impairment on production and development assets amounted to $267million; $18.9/boe (1H 2019: $287 million; $17.9/boe). This increase in DD&A per barrel is mainly attributable to decreased production.

Administrative expenses of $51 million (1H 2019: $55 million) were in line with the comparative period. In February 2020, Tullow concluded its Business Review - which included a review of the Group's organisation structure and resources. Implementation of the new organisation structure will result in a significant reduction in headcount, with an associated restructuring cost of $59 million provided for in the first half of 2020 for redundancy and onerous office lease payments.

The Group recognised a net impairment charge on property, plant and equipment of $418 million in respect of first half 2020 (1H 2019: $12million). Impairments were primarily associated with a $5/bbl reduction in the Group's long-term accounting oil price assumption to $60/bbl and lower near- term oil price forecasts.

1H 2019

Exploration cost written off ($m)

During the first half of 2020 the Group recorded exploration write-off costs of $941 million which are predominantly driven by a write-down of the value of the Ugandan assets to the value of the disposal consideration as well as a write down to the value of the Kenya assets, principally associated with the reduction of the Group's long-term oil price assumption and anticipated delay in FID. The remaining write-offs include Marina-1 well costs in Peru and the write-off of licence level costs associated with Peru, Comoros, Côte d'Ivoire and Namibia due to lower levels of planned activity and licence exits.

Derivative financial instruments

Tullow continues to undertake hedging activities as part of the ongoing management of its business risk to protect against commodity price volatility and to ensure the availability of cash flow for re-investment in capital programmes that are driving business delivery.

At 30 June 2020, the Group's derivative instruments had a net positive fair value of $197 million (30 June 2019: negative $2.4 million).

All financial instruments that are initially recognised and subsequently measured at fair value have been classified in accordance with the hierarchy described in IFRS 13 Fair Value Measurement. Fair value is the amount for which the asset or liability could be exchanged in an arm's length transaction at the relevant date. Where available, fair values are determined using quoted prices in active markets. To the extent that market prices are not available, fair values are estimated by reference to market-based transactions or using standard valuation techniques for the applicable instruments and commodities involved.

All of the Group's derivatives are Level 2 (1H 2019: Level 2). There were no transfers between fair value levels during the year.

Net financing costs

Net financing costs for the period were $131 million (1H 2019: $120 million). The increase in financing costs during the period is mainly driven by the Group ceasing to capitalise interest expenses on qualifying assets during 2019. Net financing costs include interest incurred on the Group's debt facilities, foreign exchange gains/losses, the unwinding of discount on decommissioning provisions, and the net financing costs associated with lease assets, offset by interest earned on cash deposits and capitalised borrowing costs. A reconciliation of net financing costs is included in Note 8.

Taxation

The overall net tax credit of $109 million (1H 2019: expense of $165 million) primarily relates to expenses in respect of Ghana and West Africa non-operated assets and non-recurring deferred tax credits associated with exploration write-offs, impairments and onerous lease provisions.

The Group's statutory effective tax rate is 7.6%. After adjusting for the non-recurring amounts related to exploration write-offs, impairments, restructuring costs and disposals and their associated tax benefit, the Group's adjusted tax rate is -57.7% (1H 2019: 49.0%). The adjusted tax rate has decreased due to changes in the geographical mix of profits largely generated in production territories of Ghana, Gabon and Equatorial Guinea, prior year adjustments and increased losses with no tax benefit.

(Loss) / profit after tax from continuing activities and (loss)/earnings per share

The loss after tax for the period amounted to $1,326.8 million (1H 2019: $103.2 million profit). Basic loss per share was 94.2 cents

(1H 2019: basic earnings per share of 7.4 cents).

Capital investment

Capital expenditure amounted to $192 million (1H 2019: $248 million) with $158 million invested in production and development activities and $34 million invested in exploration and appraisal activities. More than 70 per cent of the total was invested in Ghana and Kenya.

Capital investment will continue to be carefully controlled in the second half of 2020 and is expected to total c.$300 million. The capital investment total is expected to comprise Ghana capex of c.$120 million, West African non-operated capex of c.$60 million and Kenya pre-development expenditure of c.$20 million and exploration and appraisal expenditure of c.$85 million. The capital investment total excludes Ugandan expenditure of c.$15 million which is due to be reimbursed by Total when the transaction completes.

Going concern

The Group closely monitors and carefully manages its liquidity risk. Cash flow forecasts are regularly updated and sensitivities run for different scenarios, including, but not limited to, changes in commodity price and different forecasts for the Group's producing assets. The Group continues to pursue further rationalisation of its cost base through a further reduction of general & administrative (G&A) and operating costs, cuts to discretionary capital investment (for example by directing capital towards producing fields to optimise value and near-term cash flow, and substantially reducing investment in exploration and appraisal activities) and deferring decommissioning expenditure. Management has engaged a specialist consultancy firm to support the identification of further cost reduction opportunities.

The Group has performed a cash flow assessment under a Base Case and a Low Case until 30 September 2022, aligning the assessment period with the 18-month liquidity forecast test required for the Reserve Based Lending ("RBL") re-determination in March 2021, the last such re-determination which falls within the 12-month Going Concern assessment period.

Cash flow forecasts have been regularly updated in light of the oil price volatility seen in the first half of 2020, caused by the COVID- 19 pandemic (further discussed on page 10).

Management has applied the following oil price assumptions for the Going Concern assessment:

  • Base Case: $40/bbl for 2020, $45/bbl for 2021 and $50/bbl for 2022, and
  • Low Case: $30/bbl for 2020, $35/bbl for 2021 and $40/bbl for 2022.

The Low Case includes, amongst other downside assumptions, an 8% production decrease compared to the Base Case. As described on page 7, the Group benefits from its hedging policy, meaning that the impact of low oil prices in the Going Concern period is partially mitigated. Both the Base Case and the Low Case assume that the Uganda transaction will complete and that all debt is repaid in full at its contractual maturity date.

Liquidity

The Group's Base Case and Low Case scenarios forecast sufficient financial headroom for the 12 months from approval of its 2020 Half Year Results on 8 September 2020.

Management has also performed a reverse stress test and concluded that for the Group to reach zero liquidity at the end of the Going Concern period, the oil price would need to average ca. $10/bbl between 1 September 2020 and 30 September 2021,

Tullow Oil plc - 2020 Half Year Results

Page 7

assuming successful RBL re-determinations in September 2020, January 2021 and March 2021. This is deemed to be significantly below reasonable worst-case oil price assumptions for that period.

In the unlikely event that the Uganda transaction does not complete, and the Group therefore does not receive $500 million proceeds on completion, the Base Case scenario forecasts that the Group reaches zero liquidity in July 2021 as a result of the forecast repayment of the Convertible Bond. This would result in an increased projected liquidity shortfall in respect of the 18-month Liquidity Forecast Test at the January 2021 and the March 2021 RBL re-determination (see below).

Gearing covenant

The RBL Facility contains a gearing covenant, which is tested for each 12-month period ending on 30 June and 31 December each year, and which requires that net debt of the Group as defined in the RBL Facility agreement is lower than 3.5 times consolidated EBITDAX for each relevant 12-month period. Under both the Base Case and the Low Case scenarios prepared by Management, the Group's gearing is forecast to be in excess of the RBL gearing covenant when calculated at 31 December 2020 and 30 June 2021.

In order to address the forecast breach of the RBL Gearing covenant, Management will seek an amendment of the covenant in advance of the relevant assessment, or a waiver, such that the covenant will not be breached. The Directors believe that the Group would be able to secure such an amendment or waiver, which would be both consistent with past practice, most recently in June 2020 when a relaxation to 4.5 times net debt to consolidated EBITDAX was agreed ahead of the 30 June 2020 covenant test, and the Directors' reasonable expectation of the commercial interests of the Group and its lenders.

Liquidity Forecast Test

As part of each RBL re-determination process the Group is required to demonstrate to the reasonable satisfaction of the relevant majority of its lenders under the RBL Facility that it has, or will have, sufficient funds available to meet the Group's financial commitments for a period of 18 months starting from the first month immediately following the relevant RBL re-determination. In addition to the scheduled RBL re-determinations each year in March and September, the Company has requested an RBL re- determination following the Capital Markets Day later this year, with that re-determination expected to conclude in January 2021. Based on liquidity projections under the Base Case and Low Case scenarios, which assume that the Uganda transaction will complete and, as required under the terms of the RBL Facility, that all debt is repaid in full at its contractual maturity date, the Group is expected to have sufficient liquidity for the 18-month period ending in March 2022, and as such the Group is expected to pass the Liquidity Forecast Test in respect of the September 2020 RBL re-determination.

The Group's cash flow projections forecast a potential liquidity shortfall during the 18-month period relevant to the Liquidity Forecast Test in respect of the January 2021 RBL re-determination due to the maturity of the $650m Senior Notes due in April 2022. If the Group is unable to demonstrate to the reasonable satisfaction of the relevant majority of its lenders under the RBL Facility that it has, or will have, sufficient funds available to meet the Group's financial commitments for the 18-month testing period from February 2021 to July 2022 inclusive, and the Group is unable to cure the forecast liquidity shortfall within 90 days following the date on which it becomes aware that it has not passed the Liquidity Forecast Test, there will be an event of default under the RBL Facility by the end of April 2021.

Management is undertaking a comprehensive review of each of the Group's assets to maximise their value. These plans will be laid out at a Capital Markets Day before the end of the year, following which Management expects to take one or more of the following actions which it believes would be progressed sufficiently by the end of January 2021 to address the forecasted liquidity shortfall in April 2022:

  • Evaluate refinancing options for either or both of the Convertible Bonds due in July 2021 and the Senior Notes due in April 2022.
  • Seek to agree more beneficial technical and/or economic assumptions with its lenders or to amend the commercial terms of the RBL Facility in order to maintain or increase debt capacity.
  • Seek to secure new liquidity from banks or capital markets investors.

In parallel, the Directors continue to evaluate strategic opportunities and engage in discussions with third parties with a view to raising material proceeds from portfolio management, in addition to the proceeds expected to be received from the Uganda transaction.

If in the opinion of the Directors the above initiatives cannot be sufficiently progressed by January 2021 to address the forecasted liquidity shortfall in April 2022, and in the unlikely event that the Uganda transaction does not complete, the Group will initiate discussions with its creditors with a view to agreeing a financial restructuring proposal.

Implications

The Directors note that the results of some of the actions mentioned above are outside the control of the Group. If a breach of the RBL Gearing covenant in respect of either of the 12-month testing periods ending on 31 December 2020 and 30 June 2021 were to occur or the Group were not to pass the 18 months Liquidity Forecast Test at the September 2020, the January 2021 or the March 2021 RBL re-determination, and the Group were unable to negotiate amendments or waivers to its covenants, the ability of the Group to continue trading would depend upon the Group being able to negotiate a financial restructuring proposal with its creditors and, if necessary, that proposal being approved by shareholders. Whilst the Board would seek to negotiate such a financial restructuring proposal with its creditors, there is no certainty that the creditors would engage with the Board in those circumstances.

Tullow Oil plc - 2020 Half Year Results

Page 8

There would therefore be a significant risk of the Group entering into insolvency proceedings, which the Directors consider would likely result in limited or no value being returned to shareholders.

The Directors have concluded that the uncertainties associated with 1) securing amendments or waivers for the forecasted non- compliance with the RBL Gearing covenant as at 31 December 2020 and 30 June 2021 and 2) progressing sufficiently one or more of the actions outlined above, in order to pass the 18 months Liquidity Forecast Test at the January 2021 or the March 2021 RBL re- determination, are material uncertainties that may cast significant doubt that the Group will be able to continue as a Going Concern. Notwithstanding these material uncertainties, the Board's confidence in the Group's ability to obtain amendments or waivers for the forecasted non-compliance with the RBL Gearing covenant and to pass the Liquidity Forecast Test at the January 2021 and the March 2021 RBL re-determination supports the preparation of the financial statements on a Going Concern basis. The financial statements do not include the adjustments that would result if the Group were unable to continue as a Going Concern.

COVID-19 (Coronavirus)

The Company continues to monitor the ongoing COVID-19 outbreak. The key impact has been in respect of short- term oil demand and price volatility as noted in the Going Concern section above.

The Group has experience of managing infectious diseases of this nature following the significant contingency planning put in place during the West African Ebola outbreak in 2015. The Group actively monitors advice from the World Health Organisation and Public Health England, as well as participates in weekly calls with the International Oil and Gas Producers' Health Committee relating to the COVID-19 outbreak to ensure best practice precautions are being applied.

At present the threat level in the Group's countries of operation remains low, as per our Infectious Disease Health Management Guidelines, however we continue to closely monitor this as the situation develops. Clear information and health precautions on how employees should protect themselves and reduce exposure to, and transmission of, a range of illnesses along with general advice has been communicated across the organisation. In both Ghana and Kenya, the Group's in-country teams have set up their EID (Emerging Infectious Disease) Management committees in response to the current COVID-19 outbreak.

These EID Management committees steer the local management response to the outbreak, including ensuring that our contractors have implemented appropriate measures. The Company has also implemented 'self-declaration' forms for all personnel travelling to the Group's offshore assets in Ghana, that require people to sign-off that they have not been to the 'specified locations' as defined by the UK Foreign & Commonwealth Office in the last 30 days, as well as implementing business travel restrictions to and from these 'specified locations'. In the event of the COVID-19 outbreak escalating, country specific Business Continuity Plans set out how the Group proposes to continue to operate, recover quickly from, and effectively manage the response. In general, Covid-19 has had a minor impact on the Group's overall risk profile due to the controls and mitigations we have in place to manage these risks.

2020 principal financial risks and uncertainties

The Board determines the key risks for the Group and monitors mitigation plans and performance on a monthly basis. An exercise was performed in June 2020 to assess whether the principal risks and uncertainties disclosed in the 2019 Annual Report continue to be appropriate given the change in external risk landscape. Although there has been some change to sub-risks, the principal risks and uncertainties facing the Group at Half Year remain unchanged from those disclosed in the 2019 Annual Report as listed below. Consideration was given to whether a separate risk related to COVID-19 should be introduced, however it was concluded that the risks associated with COVID-19 are addressed and managed through the principal risks already in place. The company risk profile continues to be assessed on an ongoing basis including considering if the pandemic or oil price volatility results in any new risks or changes to existing risks, as well as reviewing whether mitigating actions and controls remain valid as outlined in the COVID-19 section above.

  1. Risk of major process safety, EHS incident or production failure in Ghana
  2. Risk of insufficient liquidity and funding capacity
  3. Risk of inability to make new significant oil discoveries and replenish exploration and subsurface portfolio
  4. Risk of failure to deliver commercially attractive and timely development projects
  5. Risk of disruption to business due to political/regulatory influence in Ghana
  6. Risk of failure to manage impact of climate change arising from evolving policy, regulation and carbon taxes
  7. Risk that the organisational model, people strategy and culture do not support strategy
  8. Risk of major breach of business conduct standards
  9. Risk of major cyber or information security incident

Events since 30 June 2020

There have not been any adjusting events since 30 June 2020 that have resulted in a material impact on the Half Year results.

However, there have been two non-adjusting events:

In Kenya, Tullow has been working with its Joint Venture Partners to progress the full field development plan. In May 2020 Tullow and its Joint Venture Partners declared FM on the Kenya licences. Following productive discussions with the Government, an

Tullow Oil plc - 2020 Half Year Results

Page 9

improvement in the COVID-19 situation and assurances from Government that the tax incentives granted to the phased project will continue to apply, the FM notices were withdrawn in August 2020. Whilst these issues have resulted in a delay to the Final Investment Decision (FID) on the project, it has allowed time for both Tullow and its Joint Venture Partners to collaboratively work on realising the full potential of the assets. This has resulted in the Government of Kenya agreeing to an initial extension to the Second Additional Exploration Period for the 10BB and 13T licence blocks until 31 December 2020 with a final extension until 31 December 2021, contingent on an agreed work programme and budgets. Separately, the farm down process has been suspended while the Joint Venture Partners complete a comprehensive review of the development concept to ensure it continues to be robust at low oil prices, and also consider the strategic alternatives for the asset.

At a General Meeting on 15 July 2020, the Company announced that its request for approval of the proposed sale of its entire interests in Blocks 1, 1A, 2 and 3A in Uganda and the proposed East African Crude Oil Pipeline System to Total was passed by the requisite majority of its shareholders. Over 99% of the votes cast in the poll approved the transaction.

Non-IFRS measures

The Group uses certain measures of performance which are not specifically defined under IFRS or other generally accepted accounting principles. These non-IFRS measures include capital investment, net debt, gearing, adjusted EBITDAX, underlying cash operating costs and free cash flow.

Capital investment

Capital investment is defined as additions to property, plant and equipment and intangible exploration and evaluation assets less decommissioning asset additions, right-of-use additions, capitalised share-based payment charge, capitalised finance costs, additions to administrative assets, Norwegian tax refund and certain other adjustments. The Directors believe that capital investment is a useful indicator of the Group's organic expenditure on exploration and appraisal assets and oil and gas assets incurred during a period because it eliminates certain accounting adjustments such as capitalised finance costs and decommissioning asset additions.

Net debt

Net debt is a useful indicator of the Group's indebtedness, financial flexibility and capital structure because it indicates the level of cash borrowings after taking account of cash and cash equivalents within the Group's business that could be utilised to pay down the outstanding cash borrowings. Net debt is defined as current and non-current borrowings plus non-cash adjustments, less cash and cash equivalents. Non-cash adjustments include unamortised arrangement fees, adjustment to convertible bonds, and other adjustments. The Group's definition of net debt does not include the Group's leases as the Group's focus is the management of cash borrowings and a lease is viewed as deferred capital investment. The value of the Group's lease liabilities as at 30 June 2020 was $263.5 million current and $1,063.4 million non-current; it should be noted that these balances are recorded gross for operated assets and are therefore not representative of the Group's net exposure under these contracts.

  1. Non-cashadjustments include unamortised arrangement fees which are incurred on creation or amendment of borrowing facilities as well as the Convertible Bonds which were measured at fair value. The difference between the fair value and the principal of the bond was included as a component of equity and a decrease to borrowings. Over the life of the Convertible Bond, the fair value reduces until the carrying value of the borrowings is equal to the principal outstanding for repayment on maturity.
  2. Cash and cash equivalents includes an amount of $32 million (1H 2019: $231 million) which the Group holds as operator in Joint Venture bank accounts. In addition to the cash held in joint venture bank accounts the Group had $67 million (1H 2019: $31 million) held in restricted bank accounts.

Gearing and Adjusted EBITDAX

Gearing is a useful indicator of the Group's indebtedness, financial flexibility and capital structure and can assist securities analysts, investors and other parties to evaluate the Group. Gearing is defined as net debt divided by adjusted EBITDAX. This definition of gearing differs from the one included in the RBL facility agreements. Adjusted EBITDAX is defined as profit/(loss) from continuing activities adjusted for income tax (expense)/credit, finance costs, finance revenue, gain on hedging instruments, depreciation, depletion and amortisation, share-based payment charge, restructuring costs, gain/(loss) on disposal, exploration cost written off, impairment of property, plant and equipment net, and provision for onerous service contracts.

Underlying cash operating costs

Underlying cash operating costs is a useful indicator of the Group's costs incurred to produce oil and gas. Underlying cash operating costs eliminates certain non-cash accounting adjustments to the Group's cost of sales to produce oil and gas. Underlying cash operating costs is defined as cost of sales, depletion and amortisation of oil and gas assets, underlift, overlift and oil stock movements, share-based payment charge included in cost of sales, and certain other cost of sales. Underlying cash operating costs are divided by production to determine underlying cash operating costs per boe.

  1. Depletion and amortisation of oil and gas assets is the depreciation and amortisation of the Group's oil and gas assets over the life of an asset on a unit of production basis.
  2. Under lifting or offtake arrangements for oil and gas produced in certain operations in which the Group has interests with other commercial partners, each participant may not receive and sell its precise share of the overall production in each period. The resulting imbalance between cumulative entitlement and cumulative production less stock constitutes "underlift" or "overlift". Underlift and overlift are valued at market value and included within other current assets and other current payables on the Group's balance sheet, respectively. Movements during an accounting period are charged to cost of sales rather than charged through revenue, and as a result gross profit is recognised on an entitlements basis.
  3. Share-basedpayment charge included in cost of sales relates to the portion of the non-cashshare-based payment charge that relates to employees who work on operational projects.
  4. Other cost of sales includes purchases of gas from third parties to fulfil gas sales contracts and royalties paid in cash.

Free cash flow

Free cash flow is a useful indicator of the Group's ability to generate cash flow to fund the business and strategic acquisitions, reduce borrowings and provide returns to shareholders through dividends. Free cash flow is defined as net cash from operating activities, and net cash used in investing activities, less debt arrangement fees, repayment of obligations under leases, finance costs paid, foreign exchange gain, and distribution to non-controlling interests.

INDEPENDENT REVIEW REPORT TO TULLOW OIL PLC

Introduction

We have been engaged by the Company to review the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2020 which comprises the interim condensed consolidated income statement, the interim condensed consolidated balance sheet, the interim condensed consolidated statement of changes in equity, the interim condensed consolidated cash flow statement, and the related notes 1 to 18. We have read the other information contained in the half yearly financial report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed set of financial statements.

This report is made solely to the company in accordance with guidance contained in International Standard on Review Engagements 2410 (UK and Ireland) "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company, for our work, for this report, or for the conclusions we have formed.

Directors' Responsibilities

The half-yearly financial report is the responsibility of, and has been approved by, the Directors. The Directors are responsible for preparing the half-yearly financial report in accordance with the Disclosure Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority.

As disclosed in note 1, the annual financial statements of the Tullow Oil plc are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of financial statements included in this half-yearly financial report has been prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting", as adopted by the European Union.

Our Responsibility

Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the half-yearly financial report based on our review.

Scope of Review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410, "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board for use in the United Kingdom. A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Emphasis of Matter - Material Uncertainties on Going Concern

In forming our conclusion on our review of the condensed financial statements, we have considered the adequacy of the disclosure made in note 2 of the condensed financial statements concerning the group's ability to continue as a going concern. As disclosed in note 2, the Company is forecasting to breach its Gearing Covenant in both December 2020 and June 2021 and its January 2021 and March 2021 Liquidity forecast tests currently show a shortfall. Should a covenant breach occur which is not cured within the allowed time period, the group's debt holders have the right to request repayment of the outstanding debt and to cancel the relevant facilities.

We draw attention to note 2 in the financial statements, which indicates that there are uncertainties regarding: 1) obtaining amendments or waivers for the forecasted non-compliance with the RBL Gearing covenant as at 31 December 2020 and 30 June 2021, and 2) progressing sufficiently one or more of the actions disclosed in the Finance Review in order to pass the 18 -months Liquidity Forecast Test at the January 2021 or the March 2021 RBL re-determinations. As stated in note 2, these conditions indicate that material uncertainties exist that may cast significant doubt on the company's ability to continue as a Going Concern. Our review conclusion is not modified in respect of this matter.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2020 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority.

Notes to the preliminary financial statements

Six months ended 30 June 2020

1. General information

The condensed financial statements for the six-month period ended 30 June 2020 have been prepared in accordance with International Accounting Standard (IAS) 34 Interim Financial Reporting and the requirements of the Disclosure and Transparency Rules (DTR) of the Financial Conduct Authority (FCA) in the United Kingdom as applicable to interim financial reporting.

The Condensed financial statements represent a 'condensed set of financial statements' as referred to in the DTR issued by the FCA. Accordingly, they do not include all the information required for a full annual financial report and are to be read in conjunction with the Group's financial statements for the year ended 31 December 2019, which were prepared in accordance with International Financial Reporting Standards (IFRS) adopted for use by the European Union (EU). The Condensed financial statements are unaudited and do not constitute statutory accounts as defined in section 434 of the Companies Act 2006. The financial information for the year ended 31 December 2019 does not constitute statutory accounts as defined in section 434 of the Companies Act 2006. This information was derived from the statutory accounts for the year ended 31 December 2019, a copy of which has been delivered to the Registrar of Companies. The auditor's report on these accounts was unqualified, did not include a reference to any matters to which the auditor drew attention by way of an emphasis of matter and did not contain a statement under sections 498 (2) or (3) of the Companies Act 2006.

2. Accounting policies

The annual financial statements of Tullow Oil plc are prepared in accordance with IFRSs as issued by the International Accounting Standards Board and as adopted by the European Union. The condensed set of financial statements included in this half-yearly financial report has been prepared in accordance with International Accounting Standard 34 'Interim Financial Reporting', as adopted by the European Union and the Disclosure and Transparency Rules of the Financial Services Authority.

Basis of preparation

Material Uncertainty on Going Concern

The condensed set of financial statements included in this half-yearly financial report has been prepared on a Going Concern basis.

However, the Directors have concluded that the uncertainties associated with 1) securing amendments or waivers for the forecasted non-compliance with the RBL Gearing covenant as at 31 December 2020 and 30 June 2021 and 2) progressing sufficiently one or more of the actions, outlined in the Finance Review, in order to pass the 18 months Liquidity Forecast Test at the January 2021 or the March 2021 RBL re-determination, are material uncertainties that may cast significant doubt that the Group will be able to continue as a Going Concern. Notwithstanding these material uncertainties, the Board's confidence in the Group's ability to obtain amendments or waivers for the forecasted non-compliance with the RBL Gearing covenant and to pass the Liquidity Forecast Test at the January 2021 or March 2021 RBL re-determination supports the preparation of the financial statements on a Going Concern basis. The financial statements do not include the adjustments that would result if the Group were unable to continue as a Going Concern.

The accounting policies adopted in the 2020 half-yearly financial report are the same as those adopted in the 2019 Annual report and accounts.

3. (Loss)/earnings per ordinary share

The calculation of basic (loss)/earnings per share is based on the loss for the period after taxation attributable to equity holders of the parent of $1,326.8 million (1H 2019: profit of $103.2 million) and a weighted average number of shares in issue of 1,408.9 million (1H 2019: 1,399.2 million).

4. Dividends

The Directors intend to recommend that no 2020 interim dividend be paid (2019 interim dividend: 2.35 cents/share).

5. Approval of accounts

These unaudited half year results were approved by the Board of Directors on 8 September 2020.

6. Segmental reporting

During 2020, the Group reorganised its operational structure so that the management and resources of the business are better aligned with the delivery of the business objectives. As a result, the information reported to the Group's Chief Executive Officer for the purposes of resource allocation and assessment of segment performance has changed to focus on four new Business units- Ghana, Non-operated producing assets, including Uganda, Kenya and Exploration. Therefore, the Group's reportable segments under IFRS 8 are Ghana, Non-operated, Kenya and Exploration.

The following tables present revenue, profit and certain asset and liability information regarding the Group's reportable business segments for the period ended 30 June 2020, 30 June 2019 and 31 December 2019. The table for the year ended 30 June 2019 and 31 December 2020 has been restated to reflect the new reportable segments of the business

The remaining balance of $37.9m relates to other leased assets and is included within cost of sales.

2In February 2020, Tullow concluded its Business Review - which included a review of organisation structure and resources. This will result in a 50% reduction in headcount, with an associated restructuring cost of $59 million provided for in the first half of 2020 for redundancy and onerous office lease payments. It is anticipated that the reorganisation will generate cash G&A savings of over $350 million aggregate over the next three years.

9. Taxation on (loss) / profit on ordinary activities

The overall net tax credit of $108.7 million (1H 2019: expense of $165.2 million) primarily relates to expenses in respect of Ghana and West Africa non-operated assets and non-recurring deferred tax credits associated with exploration write-offs, impairments and onerous lease provisions.

The Group's statutory effective tax rate is 7.6%. After adjusting for the non-recurring amounts related to exploration write-offs, impairments, restructuring costs and disposals and their associated tax benefit, the Group's adjusted tax rate is -58% (1H 2019: 49%). The adjusted tax rate has decreased due to changes in the geographical mix of profits largely generated in production territories of Ghana, Gabon and Equatorial Guinea, prior year adjustments and increased losses with no tax benefit.

e. Following VIU assessment as a result of reduction in long term oil price assumption, using a pre-tax discount rate of 18% f. Written down to the value of the transaction consideration. (Refer to Note 13 for further detail)

Oil prices stated in note 11 are benchmark prices to which an individual field price differential is applied. Exploration write-offs for the Kenya development area assessments are prepared on a value-in-use basis using discounted future cash flows based on 2C resource profiles. A reduction or increase in the long-term price assumptions of $15/bbl, based on the range seen in external oil price market forecasts, are considered to be a reasonably possible change for the purposes of sensitivity analysis. Decreases to oil prices would increase the exploration write-off charge by $240.3 million, whilst increases to oil prices specified above would result in a credit to the exploration write-offs of $230.8 million. A 1 per cent decrease in the pre-tax discount rate would decrease the exploration write-off by $74.9 million. The Group believes a 1 per cent change in the pre-tax discount rate to be a reasonable possibility based on historical analysis of the Group's and a peer group of companies' discount rates.

*Forward curve as at 30 June/31 December

Oil prices stated above are benchmark prices to which an individual field price differential is applied. All impairment assessments are prepared on a value-in-use basis using discounted future cash flows based on 2P reserves profiles. A reduction or increase in the two- year forward curve of $15/bbl, based on the approximate volatility of the oil price over the previous two years, and a reduction or increase in the medium and long-term price assumptions of $15/bbl, based on the range seen in external oil price market forecasts, are considered to be reasonably possible changes for the purposes of sensitivity analysis. Decreases to oil prices specified above would increase the impairment charge by $761.6 million, whilst increases to oil prices specified above would result in a credit to the impairment charge of $658.3 million. A 1 per cent decrease in the pre-tax discount rate would decrease the impairment by $52.3 million. The Group believes a 1 per cent change in the pre-tax discount rate to be a reasonable possibility based on historical analysis of the Group's and a peer group of companies' impairment discount rates.

13. Assets and liabilities classified as held for sale

On 23 April 2020, the Company announced that it had signed a Sale and Purchase Agreement with Total Uganda with an effective date of 1 January 2020, in which it agreed to transfer its entire interests in Blocks 1, 1A, 2 and 3A in Uganda and the proposed East African Crude Oil Pipeline (EACOP) System to Total.

The consideration is structured as $575 million in cash, consisting of $500 million on completion of the Transaction and $75 million following FID of the Lake Albert Development project, plus contingent post first oil payments. No contingent first oil payments have been recognised as at 30 June 2020.

Within $578.5m of Intangible exploration and evaluation assets stated below, $6.9m relates to costs capitalised during 1H 2020 which is repayable on completion. Completion of the sale is expected before the end of 2020.

As a result, this classification of Assets Held for Sale led to a $418 million write-down. Refer to Note 10.

The major classes of assets and liabilities comprising the assets classified as held for sale as at 30 June 2020 were as follows:

1Proven and Probable Commercial Reserves are as audited and reported by an independent engineer. Reserves estimates for each field are reviewed by the independent engineer based on significant new data or a material change with a review of each field undertaken at least every two years, with the exception of minor assets contributing less than 5 per cent of the Group's reserve.

2Proven and Probable Contingent Resources are as audited and reported by an independent engineer. Resources estimates are reviewed by the independent engineer based on significant new data received following exploration or appraisal drilling.

  1. The revision to reserves relates mainly to maturation of Jubilee South East Phase 1 to reserves in the Jubilee Field, TEN performance and increases at the Simba and Ruche assets in Gabon, offset by production in the first half of the year.
  2. The additional contingent resources relate to oil discoveries in Guyana.

The Group provides for depletion and amortisation of tangible fixed assets on a net entitlement basis, which reflects the terms of the Production Sharing Contracts related to each field. Total net entitlement reserves were 244.5 mmboe at 30 June 2020 (31 December 2019: 225.1 mmboe).

Contingent Resources relate to resources in respect of which development plans are in the course of preparation or further evaluation is under way with a view to development within the foreseeable future.
