#### Performnce

I am very pleased to report that we have made good

progressacross the entire business during the year.

Despite an increasingly complex and diicult geopolitical

world, together with a challenging regulatory and

operating environment, we have advanced our strategy

and key objectives.

In July 2023 the Jubilee South East development came

on stream, broadly within budget and on time. Delivery of

this key milestone has increased production at the Jubilee

ield to around 100,000 bopd and transformed our cash

generation capabilities. I was delighted to be part of the

Jubilee South East ‘First Oil’ celebrations that took place in

September last year, and I was very pleased to welcome

the President of Ghana, Nana Akufo-Addo, onboard the

Jubilee FPSO to mark this momentous occasion. We are

grateful to the Government of Ghana for their support and

I also would like to thank and congratulate our Ghana team

for their excellent operational delivery.

The safety of our people and all those who work at or

visitour sites is paramount. During the year we recorded

astrong safety performance with a 0.2 recordable injury

rate and zero Tier 1 Losses of Primary Containment.

However, our overall safety performance was not as

good as 2022 and every incident is one too many. We

are committed to the highest safety standards and we

have redoubled our eorts to reinforce our safety culture

andpractices.

We have also strengthened our balance sheet. Net debt

reduced to $1.6 billion as at year end 2023 (2022: $1.9

billion) and, during the inal quarter of 2023, we entered

into a $400 million ive-year notes facility agreement with

Glencore. This loan, which is a powerful endorsement of

our strategy, together with the $800 million of free cash

low we expect to generate over 2023 to 2025, sets us well

on course tobecoming a resilient, low-debt business.

#### Governnce

During the year, Mike Daly retired from the Board at the

AGM after nine years of service.

To replace Mike’s subsurface expertise on the Board,

we were delighted to welcome Rebecca Wiles as an

independent Non-Executive Director, following her 33-year

career at BP plc (BP). Rebecca brings signiicant emerging

market corporate experience and a wealth of commercial

and operational skills.

We were also pleased to welcome Roald Goethe as

an independent Non-Executive Director. Roald is a

highly experienced oil and gas executive with a strong

track record of buying, selling, inancing and building

businesses in Africa. Roald has spent his career at Traigura

Group, where he worked primarily in West Africa, and

Delaney Petroleum Ltd, a business he founded, trading

crude oil and petroleum products predominantly in West

Africa and the Middle East.

At the beginning of the year Richard Miller was conirmed

as Chief Financial Oicer (CFO), having served as

interim CFO since April 2022, and joined the Board as an

Executive Director.

I would like to take this opportunity to thank Mike for his

years of service and to welcome Rebecca, Roald and

Richard to the Board. Biographical information about each

Director is included on pages 70 and 71.

#### Our people

Our people are highly experienced and committed to our

purpose. They are playing a key role in Tullow’s evolution

and the Board recognises the importance of engaging with

them to understand their views and their valuable insights

about our business. During the year, Board members met

with employees on a number of occasions, including

during our annual strategy meeting in July and the Board’s

visit to Ghana in September. Our people have worked hard

and diligently to deliver the considerable progress made

during 2023. Tullow’s evolution is gaining momentum, and

I would like to thank every one of my colleagues for their

commitment, dedication and contribution.

#### Buldn  better future

Our purpose is to build a better future through responsible

oil and gas development.

If African nations are to prosper they must have access to

aordable and reliable energy and must be able to beneit

from their vast pool of natural resources. During theyear

we have continued to work eectively with our host

country governments to achieve this, including in Ghana

where the Jubilee South East development was delivered

through collaboration with a number of local suppliers.

Further information about our social and economic

contribution in Ghana is set out on page 30.

We have also continued to progress our sustainability

strategy, including our Net Zero by 2030 plan (see pages

33 and 34).

#### Concluson

Tullow is evolving. Three years ago, we were a high-

cost exploration and production company with a

geographically diverse portfolio. Today we have a clear

strategy, a disciplined inancial approach, a stronger

balance sheet and a simpliied portfolio focused on Africa.

Based on this strengthened position and the material free

cash low, the Board looks to the future with conidence.

#### Successful delver of busness pln

Soon after I joined Tullow in July 2020, we put in place

a plan to transform our business. This plan is achieving

targeted results and since the end of 2020 we have

generated over $1.1 billion of free cash low, reduced

net debt by over 30% and taken the business from peak

gearing of 3x to 1.4x net debt to EBITDAX. We have

achieved this despite our legacy hedge programme

resulting in non-recurring outlows of c.$600 million

between 2021 to 2023, which suppressed the true cash

low generation capacity of our business.

In 2023, Tullow continued to evolve and we now have a

strong and unique foundation to create material value.

Several signiicant milestones have been achieved,

including the start-up of Jubilee South East which

delivered material production growth from our core

operated ield. We generated $170 million of free cash

low, ahead of expectations, and reduced our net debt by

over $250 million, despite a lower realised oil price in 2023

compared to 2022 that drove a year-on-year reduction in

revenue (2023: $1,634 million; 2022: $1,783 million). We

also demonstrated our ability to access capital through the

$400 million debt facility agreement with Glencore.

Our strategy is underpinned by a relentless focus on three

core areas – operational excellence, capital eiciency

and business growth. Through continued execution of

this strategy, we are embedding a performance culture,

retaining our discipline, and establishing a growth outlook.

Importantly, we are now a highly cash generative business

and on track to deliver our target of c.$800 million free

cash low over the 2023 to 2025 period.

#### Sustnblt nd shred prospert

Tullow is committed to building a better future through

responsible oil and gas development. We believe Africa

has the potential to play a growing role in the global

energy mix and we actively partner with our host nations

to develop their resources in a low-cost, environmentally

and socially responsible manner. We are encouraged by

the commitment to a ‘just and equitable’ energy transition

articulated in the COP28 Agreement. This acknowledges

Africa’s minimal contribution to global emissions and

recognises the right of African developing nations to

beneit from the development of their natural resources.

Our Shared Prosperity strategy creates economic

opportunities for those who need it most. In 2023, we

accelerated our impact through partnerships, supporting

more than 10,000 students and hundreds of businesses

across our countries of operation. We are also driving local

content through increased engagement, support and

training of our local supplier base.

We have made tangible progress on our pathway to Net

Zero by 2030. In 2023, several process improvement

modiications were completed at the Jubilee and TEN

FPSOs, keeping us on track to reach our target to eliminate

routine laring by 2025. To address the hard-to-abate

residual emissions from our assets, we are taking a

hands-on approach to progress a nature-based solution

in partnership with the Ghana Forestry Commission and

expect to make a Final Investment Decision in 2024. The

project delivers on our 2030 Net Zero ambition while also

advancing Ghana’s national climate goals and aligning

with our Shared Prosperity agenda.

#### Opertonl performnce

In 2023, full year working interest production averaged

62.7 kboepd, including 6.9 kboepd of gas. Group working

interest production is expected to increase year-on-

year and our guidance range for 2024 is 62-68 kboepd,

including c.7 kboepd of gas production.

Ghn

The start-up of production from the Jubilee South East

project in July was a landmark event, marking a step

change in the ield’s production with average daily rates

c.30% higher in the second half of the year compared to

the irst half with rates reaching levels over 100 kbopd.

Gross oil production from the Jubilee ield averaged

83.4 kbopd (32.5 kbopd net) in 2023. This was below our

expectations, primarily due to water injection reliability

challenges and Jubilee South East starting up slightly later

than planned. The water injection reliability issues were

resolved in the fourth quarter of 2023, with upgraded

capacity delivering record water injection rates and

observable pressure response in the reservoirs which

will beneit 2024 production and beyond. Jubilee gas

processing was also upgraded in 2023 and as a result,

we have increased capacity to produce oil from wells

with higher associated gas content. These important

facility upgrades put us in a strong position to maintain

production in the range of 90-110 kbopd towards the end

of the decade.

Gross oil production from the TEN ields averaged 18.4

kbopd (net: 10.1 kbopd) during 2023, with improved

pressure support from existing injection wells resulting in

better management of decline. A planned shutdown was

carried out in July and work was completed to improve

asset integrity, enhance production through improved

liquid recovery from gas and reduce laring. Flaring

from TEN reduced by over 50% post the shutdown, an

important step forward in our target to eliminate routine

laring by 2025.

initially valued at $0.50/mmbtu, was amended in July 2023

to a price of $2.90/mmbtu and subsequently increased in

November to $2.95/mmbtu, after applying year-on-year

inlation indexation. This agreement represents a revenue

stream for Tullow of c.$4 million per month.

During the year, discussions continued with the Government

of Ghana on the amended TEN Plan of Development (PoD) and

the long-term gas sales agreement. We remain committed to

reaching agreement and progressing a number of identiied

projects at TEN in addition to commercialising the material gas

resource base.

In February, 2023 we announced that Tullow Ghana Limited

(TGL) had iled requests for arbitration with the International

Chamber of Commerce in London in respect of two disputed

tax assessments received from the Ghana Revenue Authority

(GRA). The assessments relate to the disallowance of loan

interest deductions for the iscal years 2010 – 2020 and

proceeds received by Tullow Oil plc during the inancial

years 2016 to 2019 under the Group’s corporate Business

Interruption Insurance policy.

Tullow had also previously iled a request for arbitration

in respect of a separate assessment for Branch Proits

Remittance Tax of $320 million in 2021. A hearing in

respect of this dispute took place in October 2023 with an

outcome expected this year.

We believe that resolution through international arbitration

will bring certainty, which is in the best interest of all

stakeholders. In the meantime, we continue to engage with

the Government of Ghana, including the GRA, with the aim

of resolving these disputes on a mutually acceptable basis.

#### Opertonl performnce contnued

Ghn contnued

During the year, our operational performance continued to

strengthen and average uptime across our Ghana FPSOs

remained high at 96%. The drilling team also had excellent

performance with seven wells (four Jubilee producers and

three Jubilee water injectors) brought onstream during

2023. The cost of drilling wells in 2023 was on average

around 20% lower and c.38 days faster than the previous

campaign in 2018-2020, achieving top-quartile industry

performance. These cost savings and eiciencies have

been driven by reducing non-productive time, improved

well design and more eective contracting.

Five new Jubilee wells (three producers and two water

injectors) are scheduled to come onstream in 2024. The

irst water injector was brought on stream in January, and

two producers were brought on stream in February, with

gross production currently averaging over 100 kbopd. We

expect to complete the current drilling programme around

the middle of the year, approximately six months ahead of

schedule. We then intend to take a drilling break in Ghana

with plans to resume drilling in 2025. During this time, we

will optimise our plans for the next phase of investment in

Ghana while the existing well stock and upgraded water

injection capacity sustains production at Jubilee and TEN

decline continues to be eectively minimised through

improved pressure support.

Net gas production in Ghana averaged 6.4 kboepd in 2023

Non-operted nd explorton portfolos

In line with expectations, production from our non-

operated portfolio in Gabon and Côte d’Ivoire averaged

13.7 kboepd net in 2023 (2022: 16.7 kboepd net), including

0.5 kboepd of gas production in Côte d’Ivoire.

Gabon is a key part of our production and infrastructure-led

exploration (ILX) portfolio and in 2023 we took actions that

place the Tchatamba facilities as a core hub for Tullow. In

April, we announced the cashless asset swap agreed with

Perenco that enabled us to take more material positions in

key ields around Tchatamba. In August, the Government

of Gabon approved the extension of several of our licences

to 2046, relecting the future potential of the ields and the

longevity of the Tchatamba facilities. 2P reserves additions

from the licence extensions and the asset swap amounts to

c.6 mmbbls with a further c.3 mmbbls 2P positive reserves

revision from asset performance, overall representing

c.190% reserves replacement in 2023. During 2024,

operations in Gabon will focus on inill drilling to sustain

production or minimise decline across the licences, as well

as two ILX wells at the Simba licence.

On Espoir in Côte d’Ivoire, we continue to work with the

operator to establish the best way forward for the asset. On

exploration licences CI-524 and CI-803, we are maturing

the prospect inventory ahead of drill candidate selection

for an exploration well to potentially be drilled in 2025.

In line with our strategy to focus on producing assets, we

no longer have licences in Guyana following the sale of

Tullow Guyana B.V. to Eco Atlantic and the expiry of the

Kanuku licence. Through the sale, which completed in

November 2023, we retain exposure to potential future

success on the Orinduik licence through contingent

considerations and royalty payments.

In Argentina, our exploration team has continued to mature

a signiicant prospective resource base and continues to

assess opportunities from these licences.

en

Kenya remains a material option to drive value and

growth for Tullow. An updated Field Development Plan

(FDP) which intends to develop 470 mmboe of 2C

resources to produce up to 120 kbopd, was submitted to

the Government in March 2023. We have since worked

collaboratively with the Government as they evaluate

the FDP. Once their evaluation is concluded, the FDP will

be submitted to the Cabinet Secretary for Energy and

Petroleum for review before submission to Parliament for

inal approval. The development has been designed to be

robust at lower oil prices and we continue discussions with

prospective strategic partners for this project.

In June 2023, our interest in Kenya increased from 50%

to 100% as a result of the withdrawal of our Joint Venture

Partners for diering reasons. The increased interest

provides us with greater strategic lexibility. While we

continue to progress the FDP, we are also actively working

with the Government of Kenya in developing options to

accelerate production and cash low to unlock value from

this well-matured resource base.

Reserves nd resources

At the end of 2023, audited 2P reserves were 212 mmboe

(2022: 229 mmboe). During the year, 23 mmboe of 2P

reserves were produced, with a replacement ratio of 26%.

Additions were primarily from the extension of production

licences in Gabon and the maturation of several inill wells,

both in Gabon and the Jubilee area. These additions were

partly oset by reductions in TEN 2P reserves, mainly driven

by a reduced near-term development programme, in light

of the ongoing delays to gain Government approval for the

TEN amended PoD. Around 30 mmboe of net gas resources

remain classiied as 2C pending the approval of the TEN

amended PoD and Gas Sales Agreement. Commercialisation

of these gas resources would place TEN on a much irmer

economic footing and support the maturation of several

identiied projects.

Tullow’s asset base continues to have signiicant value, and

as of 31 December 2023, Tullow’s audited 2P NPV10 was

$3,406 million. This is slightly down from 2022 ($3,895

million), driven largely by TEN revisions and a lower long-

term oil price assumption as deined by independent third-

party reserves auditor, TRACS.

The Group’s audited 2C resources increased to 745

mmboe at the end of 2023 (2022: 605mmboe), relecting

the material scale of opportunity Tullow has to convert

resources into reserves to sustain long-term production. As

we now hold 100% of our Kenya licences, net contingent

resources have doubled to 470mmboe. 54mmboe of

contingent resources has also been removed following the

sale and exit from Guyana.

#### Outloo

After reaching an important inlection point in our business

plan in 2023, Tullow has a strong and unique foundation to

create material value for our investors, host nations and wider

stakeholders and we look to the future with conidence.

We will continue to run our business with the same rigorous

inancial discipline, prioritising the highest returns and

focusing on value-accretive investments. Our balance sheet

will continue to strengthen as we further reduce our debt

and optimise our capital structure. We have made good

progress toward delivering our target of $800 million of free

cash low between 2023 and 2025 and given the quality of

our resource base, the opportunity set ahead of us and a

reducing cost outlook, we expect to maintain these levels of

free cash low generation in subsequent years.

With a strong balance sheet and this sustainable free cash

low outlook, our business will be well placed to deliver

value to our shareholders through organic and inorganic

growth and capital returns.

I thank our shareholders for their continued support as we

realise value across the portfolio in 2024 and beyond.

#### Mret overvew

#### A number of global dynamics are shaping the markets we operate in.

#### Geopoltcs

Geopolitical tension around the world continues

to drive uncertainty and signiicantly impact the

global economy.

During 2023, geopolitical tensions, including the conlict

in the Middle East and the ongoing war in Ukraine, have

resulted in heightened market instability and disruptions

to global trade routes, thereby creating uncertainty and

aecting global economic growth.

Across sub-Saharan Africa, our key market, political

instability has continued with several military

coup d’états occurring, including in Gabon during

August 2023.

In these geopolitically unstable times, nations are

seeking to secure domestic energy supply which

is driving a decline in global trade and increasing

energy costs.

Inlation has started to reduce towards target levels

but interest rates remain high. While most economies

are absorbing persistently high interest rates, showing

resilience over the past year, core inlation remains

elevated in several parts of the world, especially

the US and parts of Europe. If major central banks

keep interest rates higher for longer in order to tame

inlation, risks to the world economy are likely to remain

skewed to the downside

1

. In Europe, rising wages

and higher incomes are boosting the economy, but

short-term wage pressures combined with longer-

term tightness in labour markets could stoke further

inlationary pressures

2

.

In terms of global politics, in 2024, elections will take

place in the US, UK and in many countries in Africa

including Ghana, our primary country of operation.

Elections can cause signiicant market volatility as

investors cope with uncertainty about a country or

region’s direction.

#### How we re respondn

We work to build relationships with host

nations and governments. We also have a

proven track record of ensuring business

continuity during political uncertainty,

as demonstrated in Gabon where our

operations were unaected during the

recent coup.

#### Ol prces

1

For much of 2023 oil prices oscillated in a much

narrower range compared with the volatile

markets of 2022.

Oil prices luctuated in the irst six months of 2023,

following the EU’s ban on Russian crude oil imports,

interest rate hikes by global central banks, and worries

about inlation and recession. Price strength was

driven through OPEC+ cuts combined with improved

macroeconomic sentiment. Brent prices rallied in the

second half of 2023 with prices hitting yearly highs.

Russia and Saudi Arabia’s decision to extend production

cuts of a combined 1.3 mb/d through to the end of 2023

triggered a price spike towards the middle of September

2023. This raised the prospect that sustained high

interest rates may slow oil demand and economic

growth. This ambiguous demand outlook, together

with deteriorating macroeconomic indicators and a

sharp escalation in geopolitical instability in the Middle

East, saw prices increase again in early October, before

decreasing into mid-December as concerns around

wider conlict and supply disruptions eased.

Oil prices increased in mid-December following attacks

on shipping vessels in the Red Sea driving Brent up to

$78/bbl by the end of the year.

#### How we re respondn

Hedging forms a key part of our

inancial risk management and allows

us to protect our revenue from oil price

volatility. We re-introduced our hedging

policy in 2023 which sees us protect 60%

of our expected production for the year

ahead, and 30% of the following year.

We also ensure 60% of our production

is exposed to rising oil prices by using

a mixture of straight put and collar

hedge structures. We continue to focus

on reducing our costs to ensure our

business is resilient at lower oil prices.

#### Clmte chne nd ener trnston

Since the Paris agreement was signed in 2015, 75% of

cities, regions and countries now have net zero targets

enshrined in national legislation or policy. In addition,

more than two thirds of the world’s largest 2,000

companies have committed to a net zero target. With

88% of emissions, 92% of global GDP and more than

$25 trillion in revenues covered, progressing a path to

net zero has now become the global norm

1

.

Despite these developments, national climate action

plans remain insuicient to limit global temperature

rise to 1.5 degree Celsius and meet the goals of the

Paris Agreement

2

. The UNEP Emissions Gap Report

2023 showed that the growth of GHG emissions has

signiicantly slowed since 2015, but still needs to

decrease by between 28–42% more by 2030

3

.

When leaders gathered in the United Arab

Emirates for COP28, the political focus was on the

‘Global Stocktake’ to close existing gaps between

commitments, action and a 1.5C-aligned pathway

to net zero. With the UAE Presidency hailing the

agreement to transition away from fossil fuels as

“historic”, the inal text asks countries to set ‘ambitious’

targets over the next two years ‘in the light of dierent

national circumstances’. But progress on climate

adaptation, resilience and inance was slow, particularly

frustrating African nations that bear the brunt of the

impact of climate change

4

.

The uncertain geopolitical situation in 2023 is expected

to continue through 2024 and is likely to impede

further progress. Nevertheless, the consensus from

COP28 was that a more measured approach that gives

regard to the development needs of all regions is a

better approach.

While the pace of the energy transition is uncertain,

it is clear that fossil fuels such as oil, natural gas and

coal will remain a major part of the energy mix for the

foreseeable future.

African countries are disproportionately aected by

the global temperature rise – experiencing escalating

physical climate risks – but have limited ability to

respond due to debt and economic disparity . In

response, The Nairobi Declaration called for new

inancing mechanisms to restructure Africa’s debt

and unlock climate inancing

to ensure that African

countries can work together to face this challenge

#### How we re respondn

Our purpose is to build a better future

through the responsible development of

oil and gas. In support of global targets to

reduce emissions, we are implementing

our Net Zero by 2030 strategy. Further

detail about our Net Zero by 2030

strategy and progress to date is included

on pages 33 and 34.

We recognise the importance of

meaningful engagement with a wide

spectrum of stakeholders to address the

complexity of the energy transition and

we regularly engage with host countries

to understand their long-term climate-

change strategies. For example, in Ghana

we are pioneering a nature-based carbon

oset project which is aligned with

the Government of Ghana’s Reduced

Emissions from Deforestation and Forest

Degradation strategy and its Nationally

Determined Contributions under the

global Paris Agreement. This project is

being undertaken in partnership with the

Ghana Forestry Commission to mitigate

hard to abate, residual emissions. See

#### Secton 172 sttement

The Directors are required by law to act in a way that promotes the success

ofthe Company for the beneit of shareholders as a whole. In so doing they

must also have regard to wider expectations of responsible business behaviour

and have regard to the Company’s stakeholders and the matters set out in

Section 172(1) of the Companies Act 2006.

During the year the Directors have actively engaged with a number of our stakeholders to build understanding of their

position and what matters to them (see page 23). This understanding is factored into the Board’s decision-making

process. In circumstances where stakeholders’ interests are conlicted, the Directors endeavour to balance all interests

and make decisions that align with our purpose and support the delivery of the Company’s strategy and its long-

term success.

In relation to the decisions made by the Board during the year ended 31 December 2023, the Board consider, both

individually and together, that they have acted in the way they consider, in good faith, would be most likely to promote the

success of the Company for the beneit of its shareholders as a whole, having regard to its stakeholders and the matters

set out in Section 172(1) of the Companies Act 2006.

Set out below are examples of Board principal decisions made during the year which illustrate how the Directors have

fulilled their duties.

In November 2023 we entered into a $400 million ive-year notes facility agreement with

Glencore (the Agreement). The facility will be available to draw for 18 months and proceeds are

available for liability management of the Company’s senior notes maturing in March 2025. The

interest on the facility will be term secured overnight inancing rate plus 10% on drawn amounts.

We also entered into oil marketing and otake contracts with Glencore for Tullow’s crude oil

entitlements from the Jubilee and TEN ields in Ghana and the Rabi Light entitlements in Gabon.

Steholder

consdered

Investors, Colleagues, Suppliers.

Process

The Board considered the terms of the Agreement and decided it was in the best long-term

interest of the Company and the stakeholders above based on a number of factors including:

•  Proceeds from the facility, together with cash on balance sheet and free cash low expected to

be generated during 2023 to 2025, will allow all outstanding 2025 Notes to befully addressed

and positions us for a successful reinancing of the 2026 Notes.

•  By entering into the Agreement Tullow seeks to manage its debt proiles and ultimately achieve

a sustainable capital structure, including our Company goal of becoming a low-debt business

with gearing of 1x or below, and the inancial lexibility to pursue value-accretive opportunities

or consider future shareholder returns.

•  A sustainable capital structure, together with successful execution of growth opportunities, will

create value for our shareholders, lasting social and economic beneits for our host nations, job

security for our people and commercial beneits for our suppliers.

Host communities and governments, Investors, Colleagues, Suppliers.

Process

The Board considered the terms of the Agreement and decided it was in the best long-term

interest of the Company based on a number of factors including:

•  The transaction simpliies and equalises our equity ownership across key ields in Gabon, creating

better alignment between the participating interest partners and streamlining processes.

•  The transaction is aligned with our growth strategy which is focused on maximising the value

ofour key producing assets and low-risk exploration with potential for fast commercialisation,

high returns and rapid payback.

•  Successful execution of growth opportunities will create value for our shareholders, lasting

social and economic beneits for our host nations, job security and development opportunities

for our people and commercial beneits for our suppliers.

In May 2023, Tullow Kenya B.V., operator of the Company’s licence in Kenya, was informed by its

two minority partners of their intention to withdraw from Blocks 10BB, 13T and 10BA in the South

Lokichar Basin (the Project). As a result, the Group had an opportunity to increase its working

interest in these blocks and assume 100% ownership, resulting in the Company having full rights

and liabilities.

Steholder

consdered

Host governments and communities, Investors, Suppliers.

Process

The Board considered the factors associated with 100% ownership of the Project and decided it

was in the best long-term interests of the Company and its stakeholders, based on a number of

factors, including the beneits, and decided:

•  100% of the Project created more optionality, providing the Company with more lexibility in the

ongoing process to secure strategic partners. It also created a simpler joint venture partnership

and as a result, streamlined delivery.

•  The opportunity is aligned with our growth strategy. It is a low-cost development that has the

potential to unlock material value for Kenya.

#### Our sustnblt frmewor

Our sustainability strategy addresses our material economic, social and environmental impacts, and is fundamental to

delivering our purpose. It is built around four pillars (see below) which are aligned with the issues that are most relevant to

our business, our stakeholders (see page 23) and the relevant broader UN Sustainable Development Goals (SDGs).

The Safety and Sustainability Committee (see pages 87 and 88) supports the Board in directing our sustainability strategy

and targets and oversees its implementation. Sustainability-related topics are discussed at every Board meeting.

#### I believe 2024 will provide an

#### opportunity to refresh our strategy

and reassess our priorities. A focus

#### and ocean health, will be higher on

#### our agenda, for example, and we

#### will continue to reinforce the ways

There is nothing more important than the safety of our

people and all those who work at or visit our sites. Safe

operations management and practices are overseen by

the Board with the support of its Safety and Sustainability

Committee. We believe all injuries are preventable and

work proactively every day to make this our reality.

osite treatment. We also recorded three Tier 2 Loss of

Primary Containment (LOPC) incidents compared to

one Tier 2 LOPC in 2022. All injuries and incidents were

subjected to full investigations and corrective actions were

taken to prevent recurrence. In 2024, we will continue with

further intensive activities to reinforce our safety culture

through awareness and training at all levels.

continuity. We adhere to our detailed asset protection-

related policies, standards and plans which include crisis

and emergency management, ensuring employees are

fully trained to respond to emergency situations.

In 2023, we conducted two major exercises in Ghana to

test our emergency response protocols and business

continuity planning. The exercises included testing

procedures to be adopted during oshore emergencies

and to ensure our teams are updated with all relevant

procedures including full understanding of oil spill

these exercises, we adjusted our processes to improve

ouroverall emergency response preparedness.

At any given time, many workers at our facilities onshore

who works at our sites or supplies materials or services

to our facilities has a full understanding of our safety

procedures and knows our requirements on how to

comply. To engage our contractors on EHS matters,

and promote learning and sharing, we hold bi-annual

EHS Forums, with each meeting focusing on a dierent

aspect of EHS. Our irst forum of 2023 focused on ‘Safety

Leadership: The Key to Healthy and Safe Workplaces’ and

covered a number of areas including enhancing attention

to medical emergencies and ensuring ongoing learning.

#### Emploee wellness

We operate a year-round Global Wellness Agenda to

support employees in maintaining a healthy lifestyle

and we retain in-house medical professionals to provide

guidance to employees as needed. Our Employee

Assistance Programme oers individual counselling on

any personal issue, including mental health challenges.

In 2023, we again encouraged physical health with our

annual sports day and employee on-site health check-ups.

During the year, we also expanded our wellness activities

to include inancial health and ran our irst ‘Financial

Wellbeing’ seminar which was attended by 180 employees.

Employees received a ‘Wellness Afternoon O’ to support

their wellbeing. In addition, towards the end of the year

employees enjoyed a ‘Tullow Appreciation Day’, a day of

In 2023, progress was made in transitioning the FAP into a Cooperative Credit Union, with the registration of the

Fishermen Anchor Cooperative Credit Union (FACCU), which will provide continuous, aordable and easily accessible

inancial services to ishing communities in Western Ghana. The FACCU has established four district oices and recruited

ive mobile bankers to advance the provision of critical inancial services to community members. The FACCU has already

registered more than 430 members, exceeding its initial target of 400 in 2023.

#### Investn n educton

We strive to provide access to STEM education and the technical skills needed to open doors to meaningful and fulilling

careers for thousands of young people in our host countries. Working with partners in Ghana, Kenya, Guyana and

Suriname, we enabled more than 10,000 students to access education in 2023 (up from 9,000 in 2022). More than 260

students have transitioned to tertiary education and we have held 13 mentoring sessions to support students in learning

and acquiring soft skills. Concurrently we supported the training of more than 150 teachers to support and improve the

quality of teaching which is expected to beneit over 8,000 students.

Our multiple initiatives include our partnership with the Youth Bridge Foundation which manages Ghana’s Educate to

Innovate programme. Through this programme we have supported access to education and skills development and

directly engaged more than 5,000 students. We also progressed our commitment to provide $10 million over ive years

to support the Government of Ghana in providing free access to quality senior high school education. At the end of 2023,

our investment has provided accommodation and classroom facilities for more than 4,000 students across eight schools.

Our third Supplier Market Day of 2023 brought

together our local leadership and 165 suppliers

to deepen our engagement and relationships.

A delegation from the PC, led by the Director

of Local Content, Mr. Kwaku Boateng, attended

to share key insights on strategic alliances,

progressive partnerships, local content and other

licensing requirements.

#### Shred Prospert contnued

#### Proressn locl content

Local content is how we refer to advancing local

businesses in our host countries. A fundamental pillar

of our Shared Prosperity objective is the investment we

make in nurturing and engaging with local suppliers to

enhance their capabilities to grow with Tullow and expand

their activities within the oil and gas industry in their home

country and beyond.

We further expanded our collaboration with the Petroleum

Commission of Ghana (PC), providing our industry

expertise to advance local suppliers through the Ghana

Upstream Petroleum Business Academy and the PC’s

local content programme. During the year, we delivered

six training workshops through the PC/Tullow Business

Academy partnership initiative for more than 500 local

companies, as well as other joint programmes.

As part of our ongoing partnership with Accenture in

Ghana, the Tullow Supplier Mentoring and Training

Programme continues to enhance the capability of

service providers in Ghana’s upstream oil and gas sector

and improve the knowledge of PC sta. The programme

consists of online access to Accenture Supply Chain

Academy’s i-cloud learning platform as well as a tailored

one-to-one mentorship and coaching programme with

customised business support. More than 180 local

companies and 17 PC oicers have completed the

programme.

In 2023, we expanded the reach of the

LCR Tool from 30 to 45 Tier 1 suppliers

with contract values in excess of

$5 million. 100% of these suppliers

submitted information to the LCR Tool.

Our local supplier spend in 2023 was $221 million (up from

$173 million in 2022).

To further promote transparency, trust-based partnership

relationships with our suppliers and increase the

involvement of Ghanaian suppliers in our procurement

activities and operations, we hold quarterly Supplier

Market Days which raise awareness and host discussion on

speciic topics related to supply challenges in our sector.

We also publish quarterly newsletters for the beneit of our

suppliers, helping them understand how best to engage

with Tullow and providing additional opportunities for

contact with them throughout the year.

Also in 2023, we expanded the reach of our innovative,

proprietary local content reporting tool (LCR Tool), which

requests suppliers to self-report their social impact

performance against several metrics including spend on

goods and services, employment, investment in facilities

and social investments. Data from the LCR Tool enables us

#### Envronmentl stewrdshp

We are committed to being a responsible steward of the

environment and ensuring robust systems are in place for

assessing and managing environmental risk. A key focus is our

contribution to mitigating the eects of global climate change

through our commitment to Net Zero whilst preventing other

environmental impacts and protecting biodiversity.

#### Proressn our Net Zero b 2030 strte

We support the goals of the 2015 Paris Agreement, namely

to hold the increase in the global average temperature to

well below 2°C and pursue eorts to limit the temperature

increase to 1.5°C above pre-industrial levels. We have

committed to achieving Net Zero by 2030 on our Scope

1 and 2 GHG emissions on a net equity basis through a

combination of decarbonising our operated assets in Ghana

and identifying high-quality, nature-based solutions to oset

our hard to abate emissions. This plan is approved by the

Board and the senior leadership team (SLT), and led by a

Net Zero Working Group within Tullow. To deliver on our

commitment, we are prioritising the elimination of routine

laring at our Jubilee and TEN ields, which we expect will

drive down GHG emissions by at least 40% by 2025, on a net

equity basis, from a 2020 baseline. Further, we are investing

in a veriied nature-based carbon oset initiative in Ghana,

which will seek to oset 100% of our residual, hard to abate

GHG emissions.

Further information about the impact of climate change on

our business and how we are managing it is set out in our

TCFD response on pages 38 to 47.

#### Elmntn routne flrn n Ghn

Routine laring is an established method of disposing of

gas that is generated through oil production in quantities

that exceed the capacity to process it for sale or use it as an

energy source. Our strategy for eliminating routine laring,

therefore, is dependent upon increasing our gas processing

capacity at the Jubilee and TEN ields. Implementation of the

changes necessary to achieve this requires the temporary

stoppage of operations at each site to allow for switching

out of core equipment and other modiications. In 2023, we

completed the required modiications at the TEN ield that

enable the elimination of routine laring by 2025. Most of

the required modiications and upgrades in the Jubilee ield

have been completed and the remainder will be complete in

early 2025.

#### Addressn hrd to bte emssons

Our plan to address our residual, hard to abate emissions

is a nature-based initiative, working in partnership

with the Ghana Forestry Commission to oset more

than 600,000 tonnes of carbon emissions per year.

Wesigneda memorandum of understanding in January

2022 and commissioned Terra Global Capital to undertake

a feasibility study in April 2022. We expect to complete

the agreement this year with our irst carbon osets being

delivered within two years. In the meantime, we have

been engaging with stakeholders such as the Ghanaian

Environmental Protection Agency and communities in the

project landscape to gather initial feedback on needs and

expectations. Led by the Forestry Commission, we have

also conducted ield mapping work to understand the

land composition to determine deforestation rates and

potential volume from the project area. The nature-based

oset initiative covers 14 priority districts in the Bono and

Bono East regions of Ghana and the key intervention

activities to mitigate the threats of deforestation include

the generation of alternative sources of income from food

crop production and improved land management such

as ire and grazing prevention and sustainable charcoal

production. For the more than one million people living in

the project areas, this project aims to be transformational

in terms of supporting a sustainable environment,

generating work and improving livelihoods.

#### Drvn ener effcences nd emssonperformnce

During the year, in line with our Climate Policy, we have continued to drive energy eiciency through incremental

improvements across our operations and further invested in on-site renewable energy generation to replace grid power

to help drive down emissions. In the past three years, we have improved energy eiciency by 9% from 1,283 GJ per

thousand tonnes of hydrocarbon produced in 2021 to 1,168 GJ in 2023.

Our Scope 1 emissions represent more than 99.5% of our direct emissions and correlate to production and associated

laring levels. In 2023, our Scope 1 emissions increased by 4% to 2,342 thousand tonnes CO

2

e, in line with production

volumes which required a slightly higher level of laring than in the prior year. We anticipate a reduction in emissions

following the positive impact of our Jubilee and TEN modiications to enable the elimination of routine laring by 2025, as

described above.

The carbon intensity of our operated activities in 2023 was 40kg of CO

2

e per boe compared to 37kg of CO

2

e per boe

in 2022, an increase related to routine laring. Our 2023 methane emissions of 9,657 tonnes CO

2

e represent 0.4% of

our total Scope 1 and 2 emissions. Flaring is the most signiicant source of our methane emissions, which will greatly

decrease when routine laring ceases.

#### Mnn wter nd wste

Overall, our water impact is minimal and water use remains

fairly constant year on year, with minor changes due to

small dierences in operations. More than 77% of our water

withdrawal is from seawater, with zero withdrawal from

surface water sources or areas of water stress. More than

99% of the total water we withdraw is discharged back to

the sea, after treatment, thereby reducing our overall water

consumption to negligible levels. In 2023, we continued

our management of community water boreholes in our

operating regions in Kenya. On average, almost 20,000

households beneit from our water distribution which in

2023 reached 109,500 cubic metres of water.

We aspire to reduce all waste generated by our operations

with a goal of achieving zero waste to landill at all our sites.

In 2023, total non-hazardous waste generated was 352

metric tons, 35% down from 2022 with an overall reduction

in total waste of 5% and a signiicant increase in waste which

was diverted from disposal. We continue to implement a

rigorous programme of waste segregation, aiming to reduce

waste at source and recycle wherever possible. All wood

and ibre waste is recycled and we have eliminated single-

use plastics from our oices and oshore operations.

#### Protectn bodverst

We aim to protect biodiversity wherever we operate and

strive to minimise negative impacts of our operations at the

planning, exploration, development and decommissioning

phases. As well as minimising land impacts, we place

a strong focus on ocean health. In 2023, our fourth

environmental monitoring survey in Ghana to assess the

impact of our oshore operations on the marine ecosystem,

indicated that the ongoing oshore activities have not

adversely altered the general features of the sediments and

water column since our last survey in 2019.

In Ghana, we undertake marine mammal observation by

trained observers to watch and record marine mammal

sightings within the Jubilee and TEN ields as part of our

overall protocol to avoid harm to marine mammals and

turtles and we reduce disturbance to marine and coastal

ecology from vessels and helicopters by specifying travel

routes, speeds and light heights.

#### Refreshn our vlues nd empowernourpeople

In 2023, in line with the refresh of our company brand, we

updated our corporate values, engaging many colleagues

throughout the business in the process. Our aims were

to enable our people to align themselves with Tullow’s

strategy and goals and create a compelling values and

behaviours framework that will empower all our colleagues

to bring their best selves to work every day.

Our new corporate values are clear, simply expressed and

resonate with our colleagues. They are inspirational while

holding us to account for our actions in an inclusive and

empowering culture. We shared these values widely across

the organisation in an intensive period of communications,

discussions, sessions with the SLT and many in-person and

online events.

#### Enn nd empowern our people

We aim to foster an organisation in which all colleagues

are motivated to live our values and support our purpose,

while realising value for themselves in terms of meaningful

work, professional growth and competitive compensation

and beneits. We survey our employees every two years

(with frequent pulse surveys in the interim) to understand

how our Employee Value Proposition is delivering value to

our employees. The last survey was in 2022 in which 90%

of employees participated, resulting in an average positive

score of 70% across the sum of all survey questions. Our

next survey will take place in 2024.

Beyond mandatory training on ethical conduct,

compliance, health, safety and technical skills

development, we invest in providing leadership and

development training for employees to complement

functional knowledge. We aim to provide at least 20 hours

of professional development training per employee per

year. In 2023, we launched an online learning hub to give

employees access to self-training resources and support

for personal and professional development. We also put in

place a number of leadership development masterclasses

including peer-to-peer coaching to talk about challenges

and share insights. Our mentoring programme continued

during the year with a third cohort of 20 employees being

paired with 20 senior leaders to assist our colleagues with

leadership and other skills and support them in navigating

job challenges. We achieved over 7,000 hours of training

within the year.

In 2023, every Tullow permanent employee and every

contractor completed our mandatory annual online CoEC

training, which now requires self-certiied conirmation of

understanding and agreement.

This year, we reactivated our Ambassador Ethics &

Compliance programme, which plays a vital role in

promoting our culture of doing the right thing and

upholding the law: 18 volunteers from across dierent

functions and regions support our Ethics & Compliance

team by serving as focal points and trusted advisers

to their colleagues on all matters relating to our Ethics

& Compliance programme. All ambassadors received

initial training and the group meets monthly for sharing

and discussion, including deep dive learning on a

speciic topic.

We urge our colleagues to speak up if they observe, or

think they observe, behaviour which they believe is not

in alignment with our CoEC, and we encourage them to

report concerns without fear of reprisal, anonymously

if they wish. We promoted our Speaking Up process

proactively in several communications campaigns

throughout the year to ensure everyone knows what to

report and how, and feels safe in doing so if needed. In

2023, the number and nature of speaking up cases reported

detailed human rights saliency assessment. We created

a three-year roadmap that commits us to working to

enhance our human rights due diligence and prioritises

our eorts, based on eight identiied salient human rights

issues through implementation of a range of supporting

action plans.

We continued to raise awareness of human rights issues

including providing training for more than 70 employees

and over 140 suppliers. We also worked with an external

consultant, to assess and identify suppliers with potentially

high exposure to human rights risks. We rolled out the

supplier self-assessment process to 103 suppliers in Ghana

and invited them to a training session on human rights, to

ensure they understand our expectations and can seek

support to implement appropriate processes in their own

operations.

Our human rights roadmap priority actions scheduled for

2024, include:

•  Updating our Human Rights Policy and continued

We assess the impact of climate-related risks and opportunities on our business by analysing a range of metrics including

the impact on proitability, access to new markets, and cost and access to capital.

We also analyse the impact of oil prices as oil price luctuation has the most impact on our business. This approach aligns

with the metrics we use to measure our performance and the information we provide to our investors.

Using the International Energy Agency (IEA) energy scenarios below, we assess the impact on operational cash low

(OCF) generated from our existing production portfolio over 1, 5, and 10 years, which is consistent with our viability

assessment (see below).

Net zero b 2050 (NZE)

Stted polces

(STEPS)

•  Global oil demand peaks in 2035.

•  New oil and gas projects needed with shorter lead times and payback periods.

The impact to OCF per annum is calculated as a percentage for each period and reported against three broad bands of

income (see below). We do not consider future developments or exploration opportunities as it is diicult to be speciic

about the impact of the scenarios due to the high degree of uncertainty associated with future growth.

Announced pledges  -19%  -11%  -11%

NZE  -37%  -32%  -37%

Positive   Loss of up to 10%   Loss over 10%

The oil price planning assumptions we apply, as part of our annual business planning process, are generally higher

than the IEA scenarios, with the exception of the STEPS scenario from 2024 onward. Our assumptions are informed

by a range of external forecasts and our in-house expertise, which we use to determine an appropriate planning

assumption. Given the STEPS scenario is a conservative benchmark for future oil prices, relecting global policies and

implementing measures adopted as of the end September 2022, we consider our current planning assumptions to

be a fair consideration of oil market conditions over the medium term. Based on the oil price trajectories in the APS

and NZE scenarios, the IEA predicts a more challenging oil price environment should the assumptions within these

scenarios happen.

To complement our assessment of oil price impacts on OCF, we incorporate the IEA NZE emerging markets shadow

carbon price scenarios into decisions about new investments and our annual business planning cycle.

As calls for compliance-based carbon pricing mechanisms increase we continue to monitor carbon pricing mechanisms,

including emissions trading schemes, carbon taxes and carbon border adjusted mechanisms to understand the potential

impact on Tullow.

For the irst time this year we have also considered the impacts of an increased cost of capital on our business, by

running scenarios on the weighted average cost of capital. This relects our ongoing assessment of how we can access

diversiied forms of capital, that might be more expensive, to support delivery of our strategy.

In the coming year we will undertake further assessments to understand the amount and extent of our assets that are

vulnerable to climate-related physical risks. We expect this work to be completed by the end of the calendar year 2024.

The climate-related risks and opportunities that could have a potential impact on our business are detailed in the tables

on pages 41 to 43. The potential inancial impacts are set out on the next page. Further information is included in note 25

to the inancial statements.

In a worst case lood/

The impact to our business would be realised via

an increase in premium and/or lost production

with a corresponding impact to OCF, primarily as

a result of length of time to source and replace

critical spares and equipment. While these risks

are considered to be unlikely, an inventory of

critical spares and equipment required to maintain

production is under way for 2023 to further mitigate

this risk.

Based on our assessment of the likely impact of climate-related risks and opportunities on our business, together with the

actions we are taking to mitigate risk, our strategy is resilient and positions us well to fulil our purpose.

As highlighted in the tables on pages 41 to 43, our climate change risks are likely to materialise over the medium to

long term. Based on our analysis, transition risks from oil demand and price decline, carbon price exposure and access

to and cost of capital are likely to be the most material. Our strategy takes these factors into account and focuses on

infrastructure-led opportunities with short payback periods that align with host government policies.

Furthermore, to ensure our business remains resilient in a low oil price environment and generates the expected OCF,

we focus on operational excellence and run our business within a strict cost framework, allocating capital in a disciplined

way. Whilst we recognise that the IEA NZE and Announced Pledges scenarios oil price assumptions would have a

negative impact on our OCF, the medium- to long-term assumptions for the STEPS scenario would have a positive impact

on our OCF.

The Glencore facility agreement, that we secured in November 2023, demonstrates our ability to access long-term

capital from a variety of sources and is a strong endorsement of our strategy and business plan.

The climate-related risks that could impact our business

were initially identiied during a workshop that was held

in 2021. Participants in the workshop, which was led

by the sustainability team, included members from oil

marketing, production, risk, legal and exploration teams.

Our insurance team, part of Group Risk, also assess the

climate impacts to inventory held in onshore warehouses

(see more detail on page 45) and our corporate inance

team assess the climate change associated risks of access

to and cost of capital when seeking new forms of capital

(see page 41).

This year, through engagement with key internal and

external stakeholders, we commenced a double materiality

assessment to ensure that our sustainability strategy

continues to address stakeholder issues and changes in

our business and its operating environment (see page 27).

As part of this process, our transition and physical climate-

related risks, and their inancial impact, were assessed

and the risks detailed on pages 41 to 43 above were

reconirmed. These risks were subsequently considered by

the SLT and the Board as part of the annual strategy review

process. Further information about the double materiality

process can be found in our Sustainability Report which is

available at www.tullowoil.com/sustainability.

Our process for identifying and assessing climate-related

risks considers information provided by industry bodies

including the IEA and International Petroleum Industry

Environmental Conservation Association, the World Bank

and other industry and professional bodies. We also attend

workshops provided by external advisers and during the

year our legal function participated in two workshops

on climate-related legal risks, led by Freshields. We also

consider the ongoing work of the Financial Stability

Board, Network for Greening the Financial System and

key stakeholders of our host countries to inform our

assessment and understanding of risk in core regions of

operation and for various aspects of our business.

A risk-focused culture and consistent risk management framework is embedded across Tullow at all levels and is driven

by the Board. The Board is responsible for ensuring we maintain an eective risk management and internal control

system and it works closely with the SLT to ensure this is in place. The Board also oversees the processes we operate to

identify, assess and mitigate the risks that could aect our business, including those risks that could threaten our strategy,

operating model, performance, solvency and liquidity.

The Audit Committee is responsible for overseeing the process to identify principal and emerging risks and ensuring that

they are managed eectively. The Audit Committee is also responsible for overseeing our internal audit programme and,

with the support of the SLT, undertakes an annual review of the eectiveness of the internal controls we implement. The

latest review was undertaken in February 2024 and reported to the Audit Committee and the Board on 28 and 29 February,

respectively (see pages 85 and 86).

The SLT is collectively responsible and accountable for the risk management processes that operate across Tullow, with

individual members taking ownership for risks that fall in their business area.

Rs mnement contnued

#### Rs dentfcton nd ssessment

Management within each business unit are responsible for identifying the key risks in their area and for establishing

appropriate and eective management processes to control and mitigate the impact of such risks. All identiied business

unit key risks are consolidated into the business unit risk registers, which business unit management review and assess on

at least a quarterly basis taking into account likelihood of occurrence and potential impact in relation to the Company’s

risk categories (see above).

The leaders of each business unit review and re-assess the business unit risk registers covering their functional areas to

evaluate the strength of existing controls and determine whether mitigation actions need to be revised to ensure that risk

levels continue to align with the Company’s risk appetite as set by the Board.

Using the business unit risk registers, the SLT identify the principal risks which can be either a single risk or a set of

aggregated risks which, taken together, could have a signiicant impact on our strategy, performance or solvency.

Members of the SLT are assigned ownership of and are accountable for stewardship of each of the principal risks. The

SLT reviews and discusses the principal risks bi-annually to determine whether mitigations are being eectively executed

within the agreed timeframe and whether changes should be made to the principal risks, including whether any risks

should be elevated into the principal risk category.

The principal risks, together with the controls and actions to mitigate their impact, are discussed by the Board bi-annually

to provide ‘top-down’ challenge and support. The result of this review is communicated back to the SLT and the business

unit leaders to facilitate risk awareness and eective decision making throughout the organisation.

#### Our prncpl rss

Our current principal risks are set out on pages 52 to 56.

During the year, the Company’s risk proile has been closely monitored. The external economic and political landscape

including the war in Ukraine, inlationary pressures and oil price volatility have not resulted in any new risks or material

changes to existing risks.

Our assessment of the likelihood of our principal risks occurring and the potential impact after taking into account the

risk management processes and mitigation actions we implement is summarised below.

#### Vblt sttement

#### Assessment perod

In accordance with the provisions of the UK Corporate Governance Code, the Board has assessed the prospects and

the viability of the Group over a longer period than the 12 months required by the ‘Going Concern’ provision. The Board

assesses the business over a number of time horizons for dierent reasons, including the following: Annual Corporate

Budget (i.e. 2024), Corporate Business Plan (5 years i.e. 2024–2028), long-term Business Plan (10 years). The Board’s

period of assessment for the purpose of the viability statement is ive years.

#### Assessment of the Group’s prncpl rss

In order to make an assessment of the Group’s viability, the Directors have made a detailed assessment of the Group’s

principal risks (see pages 48 to 56), and the potential implications these risks could have on the Group’s business delivery

and liquidity over the assessment period. This assessment included, where appropriate, detailed cash low analysis, and

the Directors also considered a number of reasonably plausible downside scenarios, and combinations thereof, together

with associated supporting analysis provided by the Group’s Finance team. A summary of the key assumptions aligned

to the Group’s principal risks and reasonably plausible downside scenarios can be found below. It should be noted that

some assumptions encompass multiple risks but have not been repeated to avoid unnecessary duplication.

Principal risks  Base case assumption  Downside scenario

Business plan

not delivered

Production is assumed to be in line with the

Corporate Business Plan.

5% reduction in production in each year.

Geopolitical risks The Group has assumed certain cash outlows

associated with tax exposures and provisions.

The Group has included an additional

$28 million in 2024 in relation to potential

outlows. The Group has not included any

outlows associated with a negative result

from the ongoing GRA arbitrations due to its

view on the merits of these cases.

Climate change  Base case includes expenditure required to meet

2030 Net Zero commitment (a) decarbonisation

project cost to eliminate routine laring by 2025,

(b) nature-based solutions project cost to oset

hard to abate emissions.

The Group has considered an oil price

sensitivity in line with the IEA ‘Net Zero by

2050 Scenario’; see below.

Insuicient liquidity

and funding

capacity to sustain

the business

Oil price assumptions are based on the forward

curve at 31 December 2023 for two years,

followed by the Group’s Corporate Business Plan

assumption from 2026 onwards:

2024: $78/bbl 2025: $75/bbl 2026: $70/bbl

2027: $70/bbl 2028:$70/bbl

Operating costs and capital investment are

assumed to be in line with the Corporate

Business Plan.

The Group has analysed two downside

oil price scenarios; the irst is based on

the Directors’ assessment of a reasonably

plausible downside scenario:

2024: $70/bbl 2025: $70/bbl 2026: $65/bbl

2027: $65/bbl 2028: $65/bbl

The second is in line with the IEA ‘Net Zero

by 2050 Scenario’:

2024: $58/bbl 2025: $54/bbl 2026: $50/bbl

2027: $46/bbl 2028: $43/bbl

Operating costs are assumed to be 5%

higher than those included in the Corporate

Business Plan.

For detailed information on risk mitigation, assurance and progress in 2023 refer to the detailed discussion of risks on

pages 52 to 56.

For ‘ Asset integrity breach’, ‘Value not unlocked’, ‘Major accident event’, ‘Compliance or regulatory breach’, ‘Capability cannot

be attracted, developed or retained’, and ‘Major cyber-disruption’, the Group has assessed that there is no reasonably plausible

scenario that can be modelled in isolation or in combination with other risks from a cash low perspective.

Tullow Oil plc Annual Report and Accounts 2023 – 57

Financial statements Supplementary informationStrategic report Corporate governance

![]()

#### Concluson

The Group has $2.1 billion debt outstanding, maturing in 2025, 2026 and 2028. The Corporate Business Plan does not

project suicient free cash low generation to allow the Group to fully repay these debts when they fall due, and therefore

it will need to access debt markets within the viability assessment period.

In the base case, net debt and gearing are forecast to reduce suiciently such that the Directors are conident that the

Group will be able to secure the funding required to maintain adequate liquidity headroom throughout the viability

assessment period.

There is suicient liquidity for the next four years under the downside case, on the basis of securing the same amount of

funding as assumed in the base case. Management is focused on mitigating the risks around production, operating cost

increases and potential outlows associated with disputes in order to reduce the likelihood of these risks materialising,

or their impact in the event these risks materialise. Furthermore, the Directors have considered additional mitigating

actions that may be available to the Group, such as incremental commodity hedging executed in periods of higher oil

prices, alternative funding options, further rationalisation of the Group’s cost base including cuts to discretionary capital

expenditure, M&A, portfolio management and careful management of stakeholder relationships.

The IEA Net Zero case assumes a further reduction in short term oil price which if arose would result in a shortfall in

liquidity. In this scenario, management will adapt the business plan to maximise cash generation in the short to medium

term by deferring capital projects which will support the continuity of business. Based on expert forecasts for the short

term, management considers this scenario is unlikely to occur.

Based on the results of the analysis and the ability to mitigate some of the risks associated with the downside scenarios,

the Board of Directors has a reasonable expectation that the Group will be able to continue in operation and meet its

liabilities, including through reinancing activities, as they fall due over the ive-year period of their assessment.

Sles Ol volumes

During the year, there were 55,754 boepd (2022: 55,170

boepd) of liftings. The total number of liftings in Ghana is

comparable to the previous year with 13 in Jubilee (2022:

12) and 4 in TEN (2022: 5).

Relsed ol prce ($/bbl)

The Group’s realised oil price after hedging for the period

was $77.5/bbl and before hedging $84.3/bbl (2022: $88.0/

bbl and before hedging $104.3/bbl). Lower oil prices

compared to 2022 have resulted in a lower hedge loss

decreasing total revenue by $139 million in 2023 (2022:

decrease of $319 million).

Gs sles

Included in Total Revenue of $1,634 million is gas sales of

$38 million of which $29 million relates to Ghana. During

the year, Ghana exported 35,754 mmscf (gross) of gas at

an average price of $1.54/mmbtu.

#### Cost of sles

Underln csh opertn costs

Underlying cash operating costs amounted to $293 million;

$12.8/boe (2022: $267 million; $11.9/boe). Routine

operating costs largely remain unchanged from prior year.

The increase in the current year is largely due to non-

recurring expenditure.

#### Deprecton, depleton nd mortston

DD&A charges before impairment on production and

development assets amounted to $431 million; $18.8/boe

(2022: $411 million: $18.4/boe). This increase in DD&A per

barrel is mainly attributable to downward revision of TEN

and Espoir 2P reserves oset by 2022 impairments.

#### Overlft nd ol stoc movements

The overlift expense is caused by a decrease in the

underlift position in Ghana due to timing of liftings as

well as reduced stock positions in Gabon from higher

sales volumes.

#### Admnstrtve expenses

With the exception of the one-o corporate project

expenditure which was partially oset by lower insurance

premiums in the current year, Tullow has managed to

maintain administrative expenses at prior year levels

despite the inlationary environment.

#### Explorton costs wrtten off

During 2023, the Group has written o exploration costs

of $27 million (2022: $105 million) predominantly driven

by Kenya where withdrawal of the JV Partners led to a re-

assessment of risks associated to reaching FID resulting in

a $17.9 million impairment and write-os of $3.3 million in

Cote d’Ivoire, $3.4 million for the Akoum B well in Gabon

and $2.5 million in Guyana.

#### Imprment of propert, plnt

#### ndequpment

The Group recognised a net impairment charge on PP&E

of $408 million in respect of 2023 (2022: $391 million)

largely driven by a reduction in TEN reserves partially

oset by oil price and updated cost assumptions. This

was primarily due to delays in gaining approval for the

amended TEN PoD which has led to the deferral of

investment and continued ield decline. There was also

an impairment charge in Espoir due to an increase in cost

assumptions. Refer to page 191 for the full year end 2023

audited reserve and resource position. There were also

changes to estimates on the cost of decommissioning for

certain UK and Mauritania assets.

#### Gn on bond bubc

Refer to Borrowings section below.

#### Net fnncn costs

Net inancing costs for the period were $286 million

(2022: $293 million). This decrease is mainly due to lower

interest of $13 million due to the bond redemption where

interest was applied on lower outstanding bonds partially

oset by an increase in the unwinding of discount on

decommissioning provision in Ghana of $4 million.

A reconciliation of net inancing costs is included

in Note 5.

Txton

The overall net tax expense of $206 million (2022: $393 million)

primarily relates to tax charges in respect of the Group’s

production activities in West Africa, reduced by deferred

tax credits associated with future UK decommissioning

expenditure, exploration write-os and impairments.

Based on a proit before tax for the period of $96 million

(2022: $442 million), the eective tax rate is 214.3 per cent

(2022: 88.9 per cent). After adjusting for non-recurring

amounts related to gain on bond buybacks, exploration

write-os, disposals, impairments, provisions and their

associated deferred tax beneit, the Group’s adjusted tax

rate is 70.2 per cent (2022:70.3 per cent). The eective tax

rate is in line with the prior year with the impact of non-

deductible expenditure in Ghana and Gabon and no UK

tax beneit arising from net interest and hedging expense

of $167m (2022: $570m) being partially oset by deferred

tax credits related to non-operated assets undergoing

decommissioning and prior year adjustments.

The Group’s future statutory eective tax rate is sensitive

to the geographic mix in which pre-tax proits arise.

There is no UK tax beneit from net interest and hedging

expenses, whereas net interest and hedging proits would

be taxable in the UK. Consequently, the Group’s tax charge

will continue to vary according to the jurisdictions in which

pre-tax proits occur.

#### Adusted EBITDAX

Adjusted EBITDAX for the year was $1,151 million (2022:

$1,469 million). The decrease from 2022 was predominantly

due to lower revenues associated with reduced oil prices.

#### Cptl nvestment

Capital expenditure amounted to $380 million (2022:

$354 million) with $356 million invested in production and

development activities of which $288 million was invested

in Jubilee mainly comprising of $173 million spend on

drilling costs and $75 million on Jubilee South East (JSE)

and $24 million invested in exploration and appraisal

activities.

The Group’s 2024 capital expenditure is expected to

be c.$250 million and is expected to comprise Ghana

of c.$160 million, West African Non-Operated of c.$60

million, Kenya of c.$10 million and exploration spend of

c.$20 million.

#### Decommssonn

Decommissioning expenditure was $67 million in 2023

(2022: $72 million). The Group’s decommissioning

budget in 2024 is c.$70 million of which c.$20 million is

provisioning for future decommissioning in Ghana and

Gabon. Subject to programme scheduling, at the end of

2024 it is expected that c.$40 million of decommissioning

liabilities in the UK and Mauritania will remain.

#### Dervtve fnncl nstruments

Tullow has a material hedge portfolio in place to protect

against commodity price volatility and to ensure the

availability of cash low for re-investment in capital

programmes that are driving business delivery.

At 31 December 2023, Tullow’s hedge portfolio provides

downside protection for c.60% of forecast production

entitlements in the irst half of 2024 with c.$57/bbl

weighted average loors; for the same period, c.40% of

forecast production entitlements is capped at weighted

average sold calls of c.$77/bbl. In the second half of 2024,

Tullow’s hedge portfolio provides downside protection

for c.45% of forecast production entitlements with c.$60/

bbl weighted average loors; for the same period, c.20%

of forecast production entitlements is capped at weighted

average sold calls of c.$113/bbl.

For the period from June to December 2024, Tullow’s

hedge portfolio also includes three-way collars (with call

spreads) with weighted average sold calls of c.$85/bbl and

weighted average bought calls of c.$94/bbl, providing full

access to oil price upside beyond the bought call price on

c.10% of forecast production entitlements in this period.

All inancial instruments that are initially recognised and

subsequently measured at fair value have been classiied

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

(Level 1). 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

(Level 2).

All of the Group’s derivatives are Level 2 (2022: Level 2). There

were no transfers between fair value levels during the year.

At 31 December 2023, the Group’s derivative instruments

had a net negative fair value of $35 million (2022: net

negative $244 million).

purchases or exchanges in the open market or otherwise.

Refer to Note 16 – Borrowings for further detail.

#### Credt rtns

Tullow maintains credit ratings with Standard & Poor’s

(S&P’s) and Moody’s Investors Service (Moody’s).

On 21 June 2023, following completion of a bond tender

announced on 12 June 2023, S&P’s downgraded Tullow’s

#### Underln opertn csh flow nd free

#### csh flow

Underlying operating cash low amounted to $813 million

(2022: $972 million.). The decrease of $159 million is due

to decrease in net revenue of $201 million driven by lower

oil prices and higher tax payments of $21 million partially

oset by lower Gabon royalty payments of $28 million

and a one-o payment in 2022 of $77 million relating to a

historic dispute that has now been settled.

Free cash low has decreased to $170 million (2022:

$267 million) primarily due to a decrease in underlying

operating cash low of $159 million as explained above.

There has been a decrease in net cash used in investing

activities of $59 million mainly due to the one-o Ghana

pre-emption payment and Uganda FID consideration

receipt in 2022 but this has been oset by an increase

in decommissioning spend of $14 million in the

current period.

due to generation of free cash low of $170 million (as

explained above) as well as the gains on the three bond

buybacks totalling $86 million.

The Gearing ratio has increased to 1.4 times (2022: 1.3 times)

due to a decrease in Adjusted EBITDAX as explained above

primarily due to lower revenues associated with reduced

oil prices. This is in line with our target to reach gearing of

less than 1.5 times by year-end 2023.

#### Lqudt rs mnement nd

#### onconcern

The Directors consider the going concern assessment

period to be up to 31 March 2025. The Group closely

monitors and manages its liquidity headroom. Cash

forecasts are regularly produced, and sensitivities run for

dierent scenarios including, but not limited to, changes

in commodity prices, dierent production rates from the

Group’s producing assets and dierent outcomes on

ongoing disputes or litigation.

Management has applied the following oil price

assumptions for the going concern assessment:

•  Base Case: $78/bbl for 2024, $75/bbl for 2024; and

•  Low Case: $70/bbl for 2024, $70/bbl for 2025.

The Low Case includes, amongst other downside

assumptions, a 10% production decrease and 10%

increased operating costs compared to the Base Case.

Management has also considered additional outlows in

respect of all ongoing litigations/arbitrations within the

Low Case, with an additional $48 million outlow being

included for the cases expected to progress in the period

under assessment. The low case does not include the

outlow for the full exposure on Ghana BPRT arbitration of

$320 million (refer to Note 1(af) Ghana tax assessments for

details). The remaining arbitration cases are not expected

to conclude within the going concern period and no

outlows have been included in that respect.

At 31 December 2023, the Group had $1.0 billion liquidity

headroom consisting of c.$0.5 billion free cash and $0.5

billion available under the revolving credit facility.

The Group or its ailiates may, at any time and from time to

time, seek to retire or purchase outstanding debt through

cash purchases and/or exchanges, in open-market

purchases, privately negotiated transactions or otherwise.

Such repurchases or exchanges, if any, will be upon such

terms and at such prices as management may determine,

and will depend on prevailing market conditions, liquidity

requirements, contractual restrictions, and other factors.

The amounts involved may be material. The Group has

repaid $0.3 billion and $0.2 billion of the 2025 and 2026

Notes, respectively, during the year. The repayment of the

2025 Notes was partially funded by a drawdown of $130

million of the Glencore facility.

#### Lqudt rs mnement nd onconcern contnued

The Group’s forecasts show that the Group and Parent Company will be able to operate within its current debt facilities and

have suicient inancial headroom for the going concern assessment period under its Base Case and Low Case at the end of

the going concern period, including a full drawdown of the Glencore debt facility to support the payment of the 2025 Notes.

The Directors have also performed a reverse stress test to establish the average oil price throughout the going concern period

required to reduce headroom to zero, that price was determined to be $45/bbl. Based on the analysis above, the Directors

have a reasonable expectation that the Group and Parent Company has adequate resources to continue in operational

existence for the foreseeable future. Thus, they have adopted the going concern basis of accounting in preparing the Annual

Report and Accounts.

#### Events snce 31 December 2023

Gbon

On 29 February 2024, Tullow completed the Asset Swap agreement (ASA) transaction (discussed in note 14. Assets and

liabilities classiied as held for sale) with Perenco Oil and Gas Gabon S.A (Perenco). The transaction is a cashless asset

swap to be achieved through the exchange of participating interests held by both parties in certain licences in Gabon.

Management have determined that the acquisition of the additional interest in the Tchatamba licence is a Business

Combination and the inancial impacts cannot be disclosed in the Annual Report and Accounts as the measurement

ofthe assets acquired is now underway. Accordingly, the relevant disclosure will be made in the 2024 half year results.

en

On 1 March 2024 Tullow received a letter from the Energy and Petroleum Regulatory Authority (EPRA) extending the

review period of the updated Field Development Plan to 30 June 2024.

There have not been any other events since 31 December 2023 that have resulted in a material impact on the year-

end results.

#### Chr’s letter

#### During the year we have further

strengthened and refreshed the

#### Board’s composition.

Phuthuma Nhleko

Independent Non-Executive Chair

Der Shreholder,

On behalf of the Board, I am pleased to present the Corporate

Governance report for the year ended 31December 2023. We

recognise that high standards ofgovernance and eective

Board oversight are critical toTullow’s success. In this report,

we outline how the Board and its Committees have monitored

the execution of the Company’s strategy and its performance

and ensured that appropriate resources, leadership and

controls are in place to help support the creation of long-term

sustainable value for our shareholders and wider stakeholders.

Bord chnes

During the year, we further strengthened and refreshed

the composition of our Board to ensure that we have the

appropriate balance of skills and experience, and diversity

of thought, to support Tullow’s long-term success.

Following conirmation of his appointment as Chief

Financial Oicer, Richard Miller joined the Board as an

Executive Director in January 2023.

Having served nine years, Mike Daly, independent Non-

Executive Director, retired from the Board at the Annual

General Meeting (AGM) held in May 2023. Once again,

I would like to take the opportunity to thank Mike for

his service and invaluable contribution to Board and

Committee discussions.

During the year, we appointed two new independent Non-

Executive Directors. Roald Goethe joined the Board with

eect from 24 February 2023 and Rebecca Wiles joined

the Board with eect from 28 June 2023. Roald is a highly

experienced oil and gas executive with a strong track record

of buying, selling, inancing and building businesses in

West Africa. Rebecca brings deep technical subsurface

and geoscience expertise with signiicant emerging market

experience and extensive commercial and operational

experience gained during her 33-year career at BP plc.

Theirbiographical details are included onpage 71.

#### Culture

If we are to fulil our purpose we must build trust and the way

we do business is critically important. During the year we

redeined our culture and relaunched our values, to ensure

our culture continues to align with our purpose and strategy.

We are committed to fostering an inclusive, collaborative and

performance-driven culture which is underpinned by our

values: ‘Aim High’, ‘Own it’, and ‘Be True’ (see page 35). Our ‘Be

true’ value drives ethical behaviour to ensure that at all times

we do what is right. Our ‘Aim high’ and ‘Own it’ values promote

a culture of openness, empowerment, performance and

continuous improvement. In 2024, we will continue to further

embed these values throughout the organisation.

#### Dverst

The Board is comprised of a diverse mix of gender, social

and ethnic backgrounds, knowledge, personal attributes,

skills and experience. This diversity is relective of the areas

in which we do business and provides a mix of perspectives,

which contributes to eective Board dynamics.

#### Bord ledershp nd compn purpose

#### Purpose, culture, vlues nd strte

The Board is accountable to the Company’s shareholders

and wider stakeholders for the creation and delivery

of long-term, sustainable operational and inancial

performance for the enhancement of shareholder and

stakeholder value. The Board discharges its responsibilities

in a number of ways including ensuring that the Group’s

purpose, values and strategy align and that the necessary

resources are available to achieve the agreed strategic priorities.

The Board sets the Group’s core values and behaviours

which shape our culture and ensures that it takes decisions

that are aligned to our values. The Board regularly reviews

the policies implemented, including our Code of Ethical

Conduct, to ensure we continue to have the right framework

and working practices in place, ensuring that at all times

we do what is right and promote a culture of openness,

empowerment, performance and continuous improvement.

During the year we reviewed our culture and refreshed

our values. Further information about our values and this

process, is set out on page 35.

The Board utilises a number of methods to understand,

monitor and assess the Company’s culture including:

•  Employee engagement: Through its quarterly meeting

with the TAP, our employee advisory panel, the Board

has direct access to the workforce and is able to build a

better understanding of their experiences and concerns,

including the working practices that operate across

the Group. This engagement also enables the Board to

ensure alignment of our culture, purpose and strategic

priorities.

•  Safety: The Board, supported by its Committees, reviews

safety incident reports and ensures that management

deploy appropriate mitigating actions and provide

regular progress updates.

•  Site visits: As far as practicable, the Board as a collective

and/or individual Board members, undertake site visits.

These visits allow the Board to gain irst-hand experience

of our culture in action and gain a deeper understanding

of our business. During the year, the entire Board visited

our Ghana oice and met with a number of employees.

•  Policies and procedures: The Board ensures that the

right practices and processes are in place to support

our culture. These policies, which cover areas such

as sustainability, ethical conduct, anti-bribery and

whistleblowing, set our expectations of the behaviours

and practices expected, inform behaviour and embed

good decision making in line with our desired culture.

The policies are reviewed regularly and updated as

required to ensure they continue to promote the right

culture and practices that are consistent with our values.

•  Whistleblowing: The Board receives reports from the

Group’s whistleblowing facility, and regularly reviews

the eectiveness of the Group’s whistleblowing

arrangements. See page 86. In addition, the Audit

Committee’s supervision of the Group’s internal controls

framework and review of any compliance issues, informs

the Board’s assessment and monitoring of our culture.

#### Governnce frmewor

The Board operates through a governance framework

(see adjacent page) with clear procedures, lines of

responsibility and delegated authorities to ensure that our

strategy is implemented, and key risks are assessed and

managedeectively.

#### Bord meetns nd ttendnce n 2023

The Board met ive times during the year, in person. There

was an additional meeting held in July which was devoted

to an extensive review of the Group’s long-term strategy.

The September Board and Committee meetings were

held in Ghana and provided the Directors with irst-hand

insights into the Company’s operations and an opportunity

to engage with stakeholders.

In addition to the ive scheduled Board meetings,

additional unscheduled ad hoc Board calls were held

during the year to discuss speciic items. In certain

circumstances meetings are called at short notice and,

due to prior business commitments and time dierences

Directors may not always be able to attend. If a Director

is unable to attend a meeting because of exceptional

circumstances, they receive the papers in advance of the

meeting and have the opportunity to discuss any matters

they wish to raise with the relevant Chair or the Company

Secretary. Directors are provided with feedback about

decisions made at any meeting they are unable to attend.

#### Tme commtment nd externl ppontments

The expected time commitment of the Chair and Non-

Executive Directors is agreed and set out in writing in

their letter of appointment. The Board has considered

the individual Directors’ attendance, their contribution,

and their external appointments, and is satisied that

each of the Directors is able to allocate suicient time

to the Group to discharge his or her responsibilities

eectively. Asevidenced by the attendance table below,

the attendance remained high and demonstrates the

Directors’ ability to devote suicient time to their role. In

line with the Code, Directors are required to seek Board

approval prior to taking on any additional signiicant

external appointments.

#### Schedule of mtters reserved to the Bord

There are certain key responsibilities that the Board does

not delegate, and which are reserved for its consideration.

The Board’s responsibilities include: the development of

strategy; the approval of major capital expenditure; the

Group’s capital structure; the consideration of signiicant

inancing matters; and oversight of policies and procedures.

The full schedule of matters reserved to the Board is

available at www.tullowoil.com/about-us/corporate-

governance. The Board reviews the schedule on an annual

basis and the latest review took place in November 2023.

#### Conflcts of nterest

Directors have a statutory duty to avoid situations in which

they have, or may have, interests that conlict with those of

Tullow, unless that conlict is irst authorised by the Board.

The Company has procedures in place for managing

conlicts of interest. The Company’s Articles of Association

also contain provisions to allow the Directors to authorise

potential conlicts of interest so that a Director is not in

breach of his or her duty under company law.

Should a Director become aware that he or she has an

interest, directly or indirectly, in an existing or proposed

transaction with Tullow, they are required to notify the

Board in line with the Company’s Articles of Association.

If a conlict does arise, the Director is excluded from

discussions and all Directors have a continuing duty to

update any changes to their conlicts of interest.

#### Steholder enement

Enn wth our steholders

Strong relationships built on trust remain key to the

delivery of the Group’s strategy and goals. Information

about our stakeholders, including how the Board engages

with them, is set out on page 23.

During 2023 the Chair, Executive Directors and Non-

Executive Directors frequently engaged with many of

our stakeholders and the insights arising from such

engagement was considered and discussed by the Board

as a whole and taken into consideration during Board

decision making. Our Section 172 statement and examples

of how the Board took account of stakeholders in its

decision making is included on pages 24 and 25.

Worforce enement

Our people have a key role to play in Tullow’s evolution and

the Board recognises the importance of engaging with

them to understand their views and their valuable insights

about our business.

In accordance with Provision 5 of the Code, we operate

a dedicated formal advisory panel, the Tullow Advisory

Panel (TAP), which consists of eight elected colleague

representatives from across our dierent locations. The TAP

meets quarterly with members of the SLT and on separate

occasions with two independent Non-Executive Directors. The

purpose of these meetings is to discuss colleagues’ feedback

on a wide range of topics including sta development,

employee workload and diversity and inclusion, and the

Company’s strategic objectives. This forum helps to ensure

that our employees’ perspectives are considered by the Board

and its Committees in their decision-making processes. It also

provides an opportunity for the Non-Executive Directors to

hear about our business from employee’s perspectives and

gain more insight about our culture and operations. Following

their meetings with the TAP, the Non-Executive Directors

formally report to the Board on the key matters arising from

the discussions. During 2023, issues considered by the Board

following meetings of the TAP included:

•  Internal communication strategy.

•  Hybrid and lexible working arrangements.

•  Workforce remuneration arrangements.

In September 2023 the Board meeting took place in

Ghana, and all members of the Board met with a number

of our Ghana-based employees during informal receptions

and small group discussions.

AGM votn

At the 2023 AGM we received less than 80% approval for

Resolution 19, which sought authority for the Company

to purchase its own shares. The Board continued its

engagement with our major shareholders who voted

against the resolution to better understand and address

their concerns. After careful consideration, and taking into

consideration the views of our shareholders, the Directors

have decided not to seek permission for the Company to

purchase its own shares at the forthcoming 2024 AGM.

Non-Executive Directors, Rebecca Wiles and Sheila

Khama, together with Julia Ross (Director of People

and Sustainability) meeting the Chief Executive

of Youth Bridge Foundation, Seth Oteng, during

their visit to the foundation in September 2023.

We have partnered with this Ghana-based youth-

focused non-governmental organisation since 2018

to support science, technology, engineering, and

mathematics (STEM) programmes targeted at junior

and senior high school pupils in the areas where

we operate. Initiatives include mobile STEM clinics,

which provide access to science equipment and

enable pupils to undertake laboratory experiments

to aid their understanding of theoretical concepts.

Our SID, Martin Greenslade, provides a sounding board for

the Chair. The Board is fully satisied that he demonstrates

complete independence and robustness of character in

this role. The SID is available to meet shareholders if they

have concerns that cannot be resolved through discussion

with the Chair or for matters where such contact would

beinappropriate.

In addition, during the year the SID meets with the other

Non-Executive Directors, without the Chair present, to

evaluate the Chair’s performance.

#### Non-Executve Drectors (NEDs)

Our independent NEDs assess, challenge and monitor

the Executive Directors’ delivery of strategy within the risk

and governance structure agreed by the Board. As Board

Committee members, they also review the integrity of the

Company’s inancial information, consider ESG issues,

recommend appropriate succession plans, and set the

Directors’ remuneration.

#### Bord ndependence

The independence of our Non-Executive Directors is

formally reviewed annually by the Nominations Committee.

All of the Non-Executive Directors who served during the

year were considered by the Board to be independent for

the purposes of the Code and the Chair was considered

independent upon his appointment. These considerations

speciically include reference to Provision 10 of the Code

and the Director’s shareholdings in the Company.

In accordance with the Code, all of the Directors will

retire at the 2024 AGM and submit themselves for

appointment or re-appointment by shareholders. Each

of the Non-Executive Directors seeking appointment or

re-appointment are considered to be independent in

character and judgement.

The Non-Executive Directors can obtain independent

professional advice, at the Company’s expense, in the

performance of their duties.

#### Bord Commttees

The Board has delegated some of its responsibilities to

four Committees: the Audit Committee, the Nominations

Committee, the Safety and Sustainability Committee and

the Remuneration Committee (see page 72). The Board

is satisied that the Committees have suicient time and

resources to carry out their duties eectively. Their terms

of reference are reviewed and approved annually by the

Board and the respective Committee Chairs report on their

activities to the Board. The individual Committee terms of

reference are available at www.tullowoil.com/about-us/

corporate-governance/board-committees.

#### Compn Secretr

The Board is supported and advised by the Company

Secretary who ensures that it has the policies, processes,

information, time and resources it needs for it to function

eectively and eiciently. The Company Secretary is

also responsible for ensuring compliance with all Board

procedures and for providing advice to Directors when

required. The Company Secretary acts as secretary to

the Audit, Nominations, Safety and Sustainability and

Remuneration Committees and has direct access to the

Chairs of these Committees. All Directors have access

to the advice and services of the Company Secretary,

whose appointment and removal is a matter reserved for

theBoard.

#### Composton, successon nd evluton

#### Composton, slls nd experence

To ensure that the Executive Directors and senior

management possess the necessary skills and experience

required for the strategy of the business, the Board has

established a Nominations Committee (see pages 79 to 81)

to oversee the process of appointments and succession

planning for Directors and other Senior Managers. The

role of the Nominations Committee is critical in ensuring

that the Group’s Board and Committee composition and

balance support both the Group’s business ambitions and

best practice in the area of corporate governance.

The Board comprises seven independent Non-Executive

Directors and two Executive Directors. Their respective

relevant skills and experience are detailed on pages 70

and71 and below.

#### Inducton, trnn nd development

Upon joining the Board, Directors receive induction

programmes which are speciically designed to

complement their background, experience and knowledge

with a more detailed understanding of the upstream

industry and other matters regularly discussed by the

Board. The programmes include one-to-one meetings with

members of the SLT, functional leaders and, where possible,

visits to the Group’s principal oices and operations. The

Directors also receive an overview of their duties, corporate

governance policies and Board processes. As required,

professional advisers and subject matter experts are invited

to Board and Committee meetings to provide in-depth

updates. The Company Secretary also provides regular

updates to the Board and its Committee on regulatory and

corporate governance matters.

In September 2023, as part of their induction programmes,

Roald Goethe and Rebecca Wiles visited the Kwame

Nkrumah loating production storage and oloading vessel

which operates in the Jubilee oil ields o the coast of

Ghana. During the same visit to Ghana, they received a

technical ‘deep dive’ presentation on the portfolio of oil and

gas assets held by the Group in Ghana, including detail on

seismic data and capital allocation programmes. Later in

the year, they received a technical presentation in London

showcasing the people, worklows and technologies in the

subsurface realm.

Bord evluton

Each year, in line with the Code, we undertake a formal

and rigorous evaluation of the performance of the Board

and its Committees. At least every third year, this process

is facilitated by an external evaluator. Our last externally

facilitated evaluation took place in 2022 and was facilitated

by Heidrick & Struggles (the 2022 evaluation). Heidrick &

Struggles, have previously assisted Tullow with executive

searches but have no other connections with the Company.

Information about the 2022 evaluation process, its indings

and actions taken to address these indings is included in

our 2022 Annual Report and Accounts on pages 69 and 70.

#### Der shreholder

I am delighted to present the Nominations Committee (the

Committee) report for the year ended 31 December 2023.

The Committee continues to play a vital role in ensuring that

we have the right balance of skills experience, knowledge

and diversity across our leadership team. Ensuring orderly

succession planning and strong and eective leadership,

taking into account our approach to inclusion and diversity,

to support our strategy also continue to be key areas of focus.

#### Role nd responsbltes

The Committee’s key responsibilities are set out on the

previous page and outlined in the Committee’s terms of

reference which are available at www.tullowoilcom/about-

us/corporate-governance/board-committees.

#### Commttee membershp, meetns

#### ndttendnce

The Committee’s members are listed on the previous page

together with information about the number of scheduled

meetings held during the year and each Director’s

meetingattendance.

In addition to its scheduled meetings the Committee held

two unscheduled meetings to consider speciic items

including the appointments of new independent Non-

Executive Directors.

#### Non-Executve Drector successon

During the year, having assessed the skills, diversity,

experience and tenure across the Board the Committee

commissioned a search for two new Non-Executive

Directors with signiicant knowledge of our sector and

experience of operating in Africa and emerging markets.

This process led to the Committee recommending to the

Board the appointment of Roald Goethe and Rebecca

Wiles, both of whom have extensive relevant experience

and knowledge (see page 71). The Board approved both

appointments and Roald and Rebecca joined the Board on

24 February 2023 and 28 June 2023 respectively.

#### Commttee membershp chnes

During the year, and following the retirement of Mike Daly

after serving nine years on the Board, the Committee

reviewed the composition of each of the Board’s

Committee and following this review, the Committee

recommended to the Board the following changes:

•  Audit Committee: The appointment of Roald Goethe

and Rebecca Wiles as members, with eect from 24 May

2023 and 1 January 2024 respectively.

•  Safety and Sustainability: The appointment of Rebecca

Wiles as a member with eect from 1 January 2024.

•  Nominations Committee: The appointment of Sheila

Khama as a member with eect from 24 May 2023.

•  Remuneration Committee: The appointment of Roald

Goethe as a member with eect from 1 January 2024.

Following the changes to the Audit Committee as detailed

above Genevieve Sangudi stepped down as a member of

the Audit Committee, with eect from 1 January 2024.

The Board approved and welcomed these recommendations.

#### Incluson nd dverst

The Board is committed to ensuring that together

the Directors possess the requisite diversity of skills,

experience, knowledge and perspectives to support the

long-term success of the Company. The Board recognises

the role of diversity in promoting balanced and considered

decision making which aligns with the Group’s purpose,

values and strategy. All Board appointments are made on

an objective and shared understanding of merit, in line

with required competencies relevant to the Company as

identiied by the Committee.

During the year, we made great progress on our

gender diversity representation on the Board, with the

appointment of Rebecca Wiles and increasing diversity

remains one of the key focuses of the Committee.

As at the date of this Annual Report, female representation

on the Board was 33% (2022: 22%). The Committee

acknowledges the FCA’s diversity target recommendation

that at least 40% of the Board should be female and one of

the Chair or SID and/or the CEO or CFO should be female.

In line with the Parker Review, we continue to have an

ethnically diverse Board, with 44% of the Board identifying

as being ethnic minority.

We are committed to building a Board and management

team that are diverse in all respects. We are mindful of

the recommendation of the 2023 Parker Review to set a

target for 2027 for ethnic diversity, and will be considering

the appropriate target that relects the diversity of our

dynamic workforce and the areas we operate in.

The Committee also oversees the development of a

diverse pipeline for future succession to Board and senior

management appointments, including reviewing the

gender balance of senior management and its direct

reports. As at the date of this Annual Report, the SLT has

14% female representation, and among their direct reports,

female representation is 32% (excluding administrative sta).

Whilst the Committee remains committed to increasing

diversity, all appointments will be based on merit with

each candidate assessed against objective criteria, with

the prime objective to maintain and enhance the Board’s

overall eectiveness.

#### Recrutment process

The search processes for the two new Independent

Non-Executive Directors appointed during 2023 were

assisted by the search consultant Heidrick & Struggles

which, in late 2022, also assisted with an externally

facilitated evaluation of the performance of the Board,

its Committees and Directors (the 2022 evaluation). The

results and recommendations of the 2022 evaluation

(which can be found in our 2022 Annual Report and

Accounts on pages 69 and 70), together with other factors

(including stakeholder engagement) purposively informed

the scope of the searches and the skills and experience

that the Committee sought to add to the Board. Our

approach to diversity and inclusion was factored into

the search processes and a long list of candidates

was compiled taking into account the competencies

required as identiied by the Committee. This long list

was considered by the Committee and a short list of

candidates were identiied who then met with Chair,

CEO and SID. Following these meetings the Committee

recommended to the Board the appointment of Roald

andRebecca.

#### Externl ppontments

To ensure that Directors continue to have suicient time to

commit to discharge their duties, any additional external

appointments undertaken require advance approval by the

Board. The Directors signiicant external appointments are

disclosed in their biographies on pages 70 and 71.

#### Revew of Commttee effectveness

The Committee undertook a review of its eectiveness

in 2024, in respect of the year ended 31 December 2023,

with the results reported to the Board (see pages 77 and

78). Iam pleased to conirm that the Committee was

considered to be operating eectively and in accordance

with the Code and the relevant guidance. The feedback

provided has been used to shape the Committee’s annual

rolling agenda for 2024.

#### Der shreholder

#### Overvew

As the Chair of the Audit Committee, I am pleased to present

the Committee’s report for the year ended 31 December

2023. The purpose of this report is to describe how the

Committee has discharged its responsibilities during the

year. Our core objectives include ensuring the integrity of

the Group’s inancial reporting process, the eectiveness

of the external audit and ensuring that the Company has an

eective control environment to manage risks.

#### Role nd responsbltes

The Committee’s key responsibilities are set out on the

#### Commttee membershp, meetns

#### ndttendnce

In line with the provisions of the Code, all Committee

members are independent Non-Executive Directors. I have

relevant and recent inancial experience as the current

Group Chief Financial Oicer at Red Sea Global and having

served as Chief Financial Oicer at Land Securities Group

plc, a listed UK real estate company between 2005 and

2021. Previously, I spent ive years as Group Finance Director

of Alvis plc, an international defence and engineering

company. I am a Fellow of the Institute of Chartered

Accountants in England and Wales. The Board remains

satisied that I possess recent and relevance inancial

experience appropriate to Chair the Committee.

During the year, the membership of the Committee was

changed, and I am pleased to formally welcome Roald

Goethe (appointed 24 May 2023) and Rebecca Wiles

(appointed 1 January 2024) as members of the Committee.

They are both already making good contributions to the

Committee’s discussions, and I look forward to working

with them in the future. Further biographical information in

relation to Roald and Rebecca is set out on page 71.

Genevieve Sangudi stepped down from the Committee

with eect from 1 January 2024. On behalf of the

Committee, I would like to thank Genevieve for her valuable

input to the Committee over the last few years. In May

2023, Mike Daly also stepped down from the Board and

the Committee and I would also like to thank Mike for his

signiicant contribution to the Committee during his tenure.

In addition to the Committee’s scheduled meetings

during the year the Committee held conference calls

between meetings to consider speciic items. Meetings

are scheduled to allow suicient time for full discussion of

key topics and to enable early identiication and resolution

of risks and issues. Meetings are aligned with the Group’s

inancial reporting calendar. The Committee sets an

annual work plan, developed from its Terms of Reference,

with standing items that the Committee considers at each

meeting, in addition to areas of risk identiied for detailed

review and any matters that arise during the year.

#### Snfcnt ssues nd fnncl udements

The signiicant issues and primary areas of inancial judgement considered by the Committee in relation to the 2023

accounts and how these were addressed are detailed below. The related Group accounting policies can be found on

pages 134 to 144.

Carrying value of

intangible exploration

and evaluation assets

A detailed accounting paper was received by the Committee from management on

the Group’s exploration and evaluation assets, with a separate paper for Kenya, given

its materiality. The papers documented management’s assessment of indicators for

impairment and, if required, showed calculations for the impairments. The Committee

reviewed these papers and challenged management’s position, with particular focus

on the Kenya development project given key changes to the project in 2023, at the

February 2024 Audit Committee meeting.

The Committee supported management’s assessment that an impairment was

required in respect of Kenya based on the judgemental assessment performed and

ensured there was an appropriate disclosure of this judgement in the Annual Report

and Accounts.

Signiicant inancial

judgements and areas of

estimation How the Committee addressed these judgements and areas of estimation

Carrying value of

property, plant and

equipment (PP&E)

The Committee received and reviewed the papers prepared by management on the

Group’s oil price and discount rate assumptions, which are used in the assessment

of the carrying value of PP&E. At the September, November and February Audit

Committee meetings these assumptions were challenged by the Committee

compared to independent oil price forecasts. The Committee also challenged the

Company’s calculation of discount rates, with particular focus on the asset and

exploration risk adjustments made by management to a peer group weighted average

cost of capital.

At the September and February Audit Committee meetings the Audit Committee

reviewed and challenged detailed papers on management’s assessment of impairment

triggers and resulting impairment tests for PP&E. The Committee gave particular

focus to TEN, given the materiality of historical impairments made to that asset. The

Committee also discussed the Group’s reserves and resources with the Group’s

principal external reserves auditor, TRACS, at the February Committee meeting to

gain comfort over management’s view of the carrying value of PP&E. The Committee

concurred with the impairments proposed by management and ensured there was an

adequate disclosure of this judgement in the Annual Report and Accounts.

Going concern and

viability

A detailed accounting paper and cash low analysis was prepared by management

and provided to the Committee, which then reviewed and challenged the assumptions

and judgements in the underlying going concern and viability statement forecast

cash lows. The Committee discussed with management the risks, sensitivities and

mitigations identiied by management to ensure the Company can continue as a

going concern. The Committee also discussed the ive-year time horizon used by

management for the viability statement, which aligns with the revised debt maturities

following the reinancing in 2023.

The Committee concurred with management’s assessment and ensured there was an

adequate disclosure of this judgement in the Annual Report and Accounts.

Gabon asset swap A detailed accounting paper was prepared by management and reviewed by the

Committee documenting the background and accounting treatment of the Gabon

asset swap agreement and its impact on Group results. The disposal group met the

criteria for classiication as held for sale under IFRS 5 and the carrying amounts have

been presented as such on the balance sheet. On completion, any positive dierence

between the fair value of the acquired assets and the carrying value of the disposal

group will be recognised as a gain in the income statement.

TEN FPSO Lease

accounting

A detailed accounting paper was prepared by management documenting the

accounting treatment of the lease extension on the TEN FPSO following a decision

to not exercise the purchase option. The extended term has been treated as a lease

remeasurement in line with the requirements of IFRS 16, and the discount rate and

lease term have been updated to relect the new expected end date. The adjustments

were made to the right-of-use asset and liability on the balance sheet.

The Committee concurred with management’s assessment and ensured there was an

adequate disclosure of this judgement in the Annual Report and Accounts.

Uncertain tax and

regulatory treatments

Detailed accounting papers on all tax and regulatory exposures were prepared

by management for the Committee’s review. Where relevant, the papers included

summaries of external legal or tax advice on particular tax claims and assessments

received. The Committee also met with the Head of Tax in the February meeting to

discuss and challenge the key judgements and estimates made including the likelihood

of success and the quantum of the total exposure for which provision had been made.

The Committee concurred with management’s assessment and ensured there was an

adequate disclosure of this judgement in the Annual Report and Accounts.

Externl udtor

The Committee has primary responsibility for managing the

relationship with the external auditor, including assessing

its performance, eectiveness and independence,

recommending to the Board its re-appointment or removal,

and agreeing terms of engagement.

Based on the competitive tender process conducted

in 2018, the Committee recommended to the Board

the appointment of Ernst & Young LLP (EY) as Tullow’s

statutory auditor for the 2020 inancial year, which was

approved by shareholders at the 2021 AGM. Under current

regulations, the Group will be required to retender the

audit by no later than the 2029 inancial year.

The external auditor is required to rotate the audit partner

responsible for the Group audit every ive years. Mr Paul

Wallek is EY’s lead audit partner with eect from 2020.

During the year the Committee held private meetings with

the external auditor, and I also maintained regular contact

with the audit partner throughout the year. These meetings

provide an opportunity for open dialogue with the external

auditor without management being present, and help

ensure that the external auditor is able to operate eectively

and challenge management suiciently when required.

#### Effectveness of externl udt process

The Audit Committee is responsible for assessing the

qualiications, expertise and resources, and independence

of EY, as well as the eectiveness of the audit process. The

Committee’s assessment of the 2023 audit process covered

all aspects of the audit service provided by EY, including:

•  Obtaining a report on the auditor’s own internal quality

control procedures and consideration of the auditor’s

annual transparency reports in line with the Code.

•  Approving the auditor’s terms of engagement

andremuneration.

•  Reviewing and approving the audit plan prepared by

the auditor at the start of the audit cycle. This plan

identiies key audit risks which included oil and gas

reserve estimations; recoverability of Kenya exploration

and evaluation assets; recoverability of property plant

and equipment; going concern; revenue recognition;

uncertain tax treatments and accounting for the Gabon

asset swap.

•  Discussing and challenging a number of matters

including the auditor’s assessment of the Group’s

signiicant inancial risks and the performance of

management in addressing these risks, the auditor’s

opinion of management’s role in fulilling obligations

for the maintenance of internal controls and the

transparency and responsiveness of interactions

withmanagement.

•  Conirming the independence of the audit including

how the auditor has exercised professional challenge.

•  Assessing the eectiveness and performance of the

external auditor and the audit process based on the

Committee’s interactions with the external auditor and

management’s survey.

As a result of the Committee’s assessment, the Committee

concluded that the external audit process had operated

eectively. EY and management have agreed on step

plans to ensure the quality of audit, team continuity and

focus on continuous improvement is maintained.

#### Non-udt servces nd ndependence

The Committee closely monitors the level of audit and

non-audit services provided by the auditor to the Group.

Non-audit services are normally limited to assignments

that are closely related to the annual audit or where the

work is of such a nature that a detailed understanding

of the Group is necessary. An internal Tullow standard

for the engagement of the auditor to supply non-audit

services is in place to formalise these arrangements.

Itwas revised in January 2022 and is reviewed regularly.

Itrequires Committee approval for all non-trivial categories

of non-audit work. In 2023 total fees for audit-related work

amounted to $2.5 million and total fees for non-audit-

related work amounted to $0.5 million. See note 4 to the

inancial statements for further information.

In addition to processes put in place to ensure segregation

of audit and non-audit roles, EY is required, as part of the

assurance process in relation to the audit, to conirm to the

Committee that it has both the appropriate independence

and the objectivity to allow it to continue to serve the

Company’s shareholders. This conirmation is received

every six months, and no matters of concern were

identiied by the Committee.

#### Internl controls nd rs mnement

The Board has overall responsibility for risk management

and internal control systems, and for reviewing their

eectiveness. This process is overseen by the Committee

on the Board’s behalf.

In 2023, the Committee reviewed, discussed and briefed

the Board on risks, controls and assurance, including the

annual assessment of the system of risk management

and internal control, to monitor the eectiveness of the

procedures for internal control over inancial reporting,

compliance and operational matters.

The Directors obtained comfort over the eectiveness of

the Group’s risk management and internal control systems

through various assurance activities that included:

•  Audits undertaken by the Internal Audit team.

•  Enterprise risk management and assurance processes.

•  The external auditor’s observations on internal inancial

controls identiied as part of its audit.

•  Regular performance, risk and assurance reporting by

the Business Unit and Corporate teams to the Board.

#### Internl controls nd rs mnement

#### contnued

During the year, in conjunction with the Board, the

Committee completed two robust assessments of the

signiicant risks facing the Company, including those that

would threaten its business model, future performance,

solvency or liquidity. This assessment included the

identiication and discussion of principal and emerging

risks. The assessment process included engagements with

the SLT helping to support understanding, ownership and

accountability of enterprise-wide risks across all layers of

the Company. For each of the principal risk categories, the

Board reviewed the risk strategies to ensure they were still

valid, and their associated risk appetites.

Internal Audit periodically presented its indings to the

Committee over delivery of the assurance plan, progress

of issues raised and their timely resolution. On occasions,

senior management representatives from the business

were also invited to attend the Committee to provide

updates on key matters such as the annual tax strategy

review and TCFD reporting.

In addition, during the year, the Committee received reports

from the principal independent reserves auditor TRACS and

reviewed the arrangements in place for managing cyber risk

relating to the Group’s critical information systems.

All identiied indings were assessed, with no indications of

fraud noted.

Based on the results of the annual eectiveness review

of risk management and internal control systems, the

Directors concluded that the system of internal controls

operated eectively throughout the inancial year and

up to the date on which the inancial statements were

signed. There were areas identiied for improvement and

the Directors are conident that they are in the process of

being addressed.

#### Internl udt requrements

The Committee’s role is to consider how the Group’s

internal audit requirements are satisied and make relevant

recommendations to the Board. Throughout 2023

the Committee requested and received reports from

management on its resource and budget planning for the

Internal Audit function in order to assess the eectiveness

of internal audit and satisfy itself that the quality, experience

and expertise of the function is appropriate for the business.

The level of internal resource available to the function was

in line with target from throughout the year. In addition, the

internal audit function uses external expertise for specialist

reviews and so the Committee challenged management to

ensure suicient budget was made available for additional

external resource where required.

During the year:

•  The Committee reviewed and challenged the 2023

programme of internal audit work developed to address

both inancial and overall risk management objectives

identiied within the Group during the planning phase. The

plan was subsequently adopted with progress reported

at the Committee’s meetings and feedback provided. A

total of 19 internal audits were planned for 2023 of which

15 were completed with two in progress at the year end,

one review was postponed into 2024 and two reviews

were consolidated into one. The primary changes in the

plan were due to re-assessments of the Group’s priorities

and the results of completed audits. Based on the nature

of the audits completed, the assurance performed by

management, the Committee’s subsequent assessment

and the scale of the business, the Committee believes an

appropriate level of assurance has been performed over

the Group’s internal control environment.

•  Internal Audit also ran a systematic programme of audits

of suppliers’ compliance with contractual terms, with a

focus on signiicant and high-risk contracts.

•  Detailed results from the internal audits were reported to

management and in summary to the Committee during

the year. Where required, the Committee receives full

reports and details on any key indings and receives

regular reports on the status of the implementation of

Internal Audit recommendations.

•  The Committee assessed the eectiveness of Internal

Audit through meeting with the Head of Internal Audit,

its review and assessment of the Internal Audit Plan and

the results of audits reported.

#### Whstleblown procedure

In line with best practice and to ensure we operate

to the highest ethical standards, an independent

whistleblowing procedure was established in 2011 and

operated throughout 2023. The procedure allows sta to

conidentially raise any concerns about business practices

and complements our internal reporting processes. The

Committee considers the whistleblowing procedures to be

appropriate for the size and scale of the Group.

The whistleblowing policy is included in the Code of

Ethical Conduct which is available to all sta in printed

form and on our intranet. Each member of sta is annually

required to complete an online awareness course to refresh

their knowledge of key provisions of the Code of Ethical

Conduct, which was included as a Group-wide KPI.

The Committee receives from the Group Ethics and

Compliance Manager summaries of investigations of

signiicant known or suspected misconduct by third

parties and employees including ongoing monitoring

andfollowing up of internal investigations.

#### Revew of Commttee effectveness

The Committee undertook a review of its eectiveness in

2024, in respect of the year ended 31 December 2023, with

the results reported to the Board (see pages 77 and 78). I am

pleased to conirm that the Committee was considered to be

operating eectively and in accordance with the Code and

the relevant guidance. The feedback provided has been used

to shape the Committee’s annual rolling agenda for 2024.

#### Der shreholder

#### Overvew

The Safety and Sustainability Committee oversees

our sustainability strategy and performance in relation

to its four pillars: Safe Operations, Shared Prosperity,

Environmental Stewardship and Equality and Transparency.

2023 was another active year for the Committee during

which several strategic programmes were advanced

across all four sustainability pillars.

#### Role nd responsbltes

The Committee’s key responsibilities are set out on the

previous page and outlined in the Committee’s terms of

reference which are available at www.tullowoil.com/aboutus/

corporate-governance/board-committees.

#### Commttee membershp, meetns

#### ndttendnce

The Committee’s members are listed on the previous

#### Commttee ctvtes

To ensure that sustainability is embedded across all

business activities and decision making, at each meeting the

Committee reviews the sustainability KPI which forms part of

the Group’s scorecard (see pages 20 and 21). As needed, the

Committee also conducts in-depth reviews of strategically

important areas of concern for the Group.

In 2023, the Committee engaged across several topics

which are core to our sustainability performance and

progress. Personal and process safety continued to be an

important discussion at every meeting and the Committee

reviewed all notable safety events including signiicant

safety events and high-potential near misses. This included

a lost-time injury on the Jubilee FPSO in which an oshore

worker required osite medical treatment. The Committee

reviewed the thorough investigation of the incident

which took place and corrective actions to prevent similar

incidents. Similarly, the Committee reviewed ongoing

investment in life cycle integrity and maintenance of

operated assets and new safety campaigns such as

‘Learning from Normal Work’ and enhanced safety

hazard risk management practices. The Committee also

examined safety risk mitigation at non-operated assets.

Advancing plans to deliver our Net Zero Scope 1 and 2

emissions by 2030 commitment, and the interim goal

of eliminating routine laring by 2025, were a regular

feature of the Committee’s agenda in 2023, and included

updates on the implementation of modiications at Jubilee

and TEN ields to enable elimination of routine laring.

Additionally, the Committee played an instrumental role in

considerations leading to the agreement to partner with

the Ghana Forestry Commission in a project which will

oset more than 600,000 tonnes of carbon emissions per

year, representing 100% of Tullow’s residual hard to abate

emissions. The Committee is supportive of the agreed

hands-on approach, which involves upfront investment,

aligning on carbon standards, engagement with

communities in the project regions in Ghana to improve

livelihoods and deliver environmental beneits.

During the year, in relation to our human rights policy, the

Committee considered the salient issues most relevant

to our business activities. Following this review the

Committee oversaw the development of a new human

rights roadmap and the development of plans to further

strengthen the protection of human rights across the

Group (see page 37).

The Committee continued to monitor delivery of our

Shared Prosperity strategy including ongoing educational

initiatives in host countries, accelerated through

partnerships with experienced local organisations.

The outcomes of these activities in terms of improved

enrolment in education, higher school grades and

stronger interest in STEM higher education represent an

important contribution to delivering Shared Prosperity

in the communities where we operate. Similarly, the

Committee reviewed local content performance, including

the positive development of collaboration with the Ghana

Petroleum Commission to broaden and deepen the nature

of knowledge and the extensive engagement and support

provided to local suppliers and entrepreneurs.

The Committee evaluated and agreed the Group’s

sustainability disclosures including the annual

Sustainability Report and its TCFD statement (see pages

38 to 47).

#### Revew of Commttee effectveness

The Committee undertook a review of its eectiveness

in 2024, in respect of the year ended 31 December 2023,

with the results reported to the Board (see pages 77 and

considered to be operating eectively and in accordance

#### Annul sttement on remunerton

#### Der shreholder

On behalf of the Board, I am presenting the Remuneration

Committee’s report for 2023 on Directors’ remuneration.

The report is divided into three main sections:

•  This Annual Statement, which contains a summary of

performance and pay for 2023, the Committee’s activities

during the year, and the proposed implementation of the

Directors’ Remuneration Policy for 2024.

•  The 2023 Annual Report on Remuneration, which

provides details of the remuneration earned by Directors

in the year ended 31 December 2023 and how the Policy

will be operated in 2024.

•  The Directors’ Remuneration Policy Report, which was

formally approved by the shareholders at the 2023 AGM

and sets out the forward-looking three-year Directors’

Remuneration Policy for the Company.

#### New Drectors’ Remunerton Polc

#### pproved t the 2023 AGM

As disclosed last year the Committee undertook a

comprehensive review of the Directors’ Remuneration Policy

in 2022 and early 2023, which included consultation with

many of our major shareholders. Following this process it was

pleasing to see the strong support for the Policy at our 2023

AGM, with the Policy report receiving a 98.6% vote in favour.

The feedback received from shareholders during this

consultation helped inform the Committee’s decisions

on the inal terms of the Policy, and has continued to

form part of the Committee’s discussions during the

year. Iwould like to thank those who took part in the

consultation exercise for their time and input.

#### 2023 performnce context

During the year, we made material inancial and operational

progress. A key event in the year was the start-up of the

Jubilee South East (JSE) project which delivered material

production growth from the ield and in turn, marked a step-

change in our cash low generation. We also reined our non-

operated portfolio through a swap agreement and licence

extensions in Gabon. $170 million of free cash low was

generated during the year, which was ahead of expectations,

and we secured a $400 million debt facility agreement with

Glencore, which demonstrates our ability to access long-

term capital. We further strengthened our balance sheet

though continued deleveraging and proactive buy-backs of

our bonds. We remain on track to deliver our target of c.$800

million free cash low over the 2023 to 2025 period and

create an optimal capital structure.

2023 full-year production was 62.7 kboepd, marginally

below expectations due to water injection challenges and

a short-term delay to the start up of the JSE project. This

production generated revenue of $1,634 million (2022:

$1,783 million); gross proit of $765 million ($1,086 million)

and a loss after tax of $110 million (2022: proit after tax

of $49 million). This loss was driven by impairments and

write-os totalling $435 million.

Remunerton report contnued

We are pleased with the operational and inancial progress

made during the year to position Tullow for growth.

Summr of Executve Drector

#### remunerton for 2023

As set out in the Policy, 2023 was a transitionary year as

we move from the Tullow Incentive Plan (TIP) to separate

annual bonus and LTIP awards. Rahul Dhir’s 2023 variable

pay was therefore earned under the TIP, whereas Richard

Miller, due to his appointment as CFO in January 2023, was

eligible for an annual bonus.

Following the end of the year the Committee reviewed

the performance achieved against the KPI scorecard used

for annual bonus awards. For TIP awards the scorecard

also included a 50% element based on relative TSR. The

details of the scorecard and the performance achieved

can be found on pages 93 to 96. It was noted that there

had been resilient performance across a number of our

KPIs including safety, inancials, production, business plan

implementation, sustainability, unlocking value, leadership

eectiveness and capital structure.

Based on this assessment the Committee awarded

Rahul Dhir a TIP award of 106% of salary (i.e. 26.5% of the

maximum 400% of salary potential), which takes into

account the progress against annual KPIs and the three-

year TSR measurement period, which commenced 1 January

2021 and ended 31 December 2023. In line with the Policy,

50% of the TIP award is paid in cash, with the remaining 50%

deferred into shares which vest after ive years.

Based on performance against the annual KPIs, the

Committee felt it appropriate to award an annual bonus to

Richard Miller of 79.5% of salary (i.e. 53% of the maximum

150% of salary opportunity). In line with the Policy, one- third

of the bonus earned will be deferred into shares for a

period of three years.

The Committee considers these outcomes to be appropriate

in the context of the performance achieved over the relevant

period and has not applied discretion to the outcome.

As disclosed last year, in June 2023 we granted the irst LTIP

awards under the Policy to Rahul Dhir and Richard Miller, which

are subject to performance over the three years from 1 January

2023. To determine the number of underlying shares for each

LTIP award, the Committee decided to apply the same share

price as used to determine the March 2023 TIP share awards in

relation to the 2022 performance year, which was 17% higher

than the share price on the day the LTIP awards were made.

Details of these awards can be found on page 100.

Summr of Executve Drector

#### remunerton for 2024

In early 2024 the Committee reviewed the salary levels for

the Executive Directors, taking into account the average

pay increase awarded to UK-based employees of 3.5%.

The base salary for Rahul Dhir, our CEO, will be increased

by 2.8%, below the typical increase awarded to UK based

employees for 2024. Richard Miller, our CFO, was appointed

on 1 January 2023 and his salary on appointment was set

at a level that considered that this was his irst FTSE CFO

role. During 2023 his performance has been strong, he

90 – Tullow Oil plc Annual Report and Accounts 2023

Financial statements Supplementary informationStrategic report Corporate governance

![]()

0.0%

has gained signiicant experience and he has continued to

develop in the role. Therefore, the Committee determined

that it was fair and appropriate to increase his base salary

by 9.3%. Following this increase the CFO’s base salary will

remain below that of his predecessor. Base salary increases

will apply with eect from 1 April 2024.

As set out in the approved Policy, 2024 will be the inal

transition year for Rahul Dhir, with performance for the 2022

to 2024 period continuing to be rewarded through the TIP.

This will be based 50% on relative TSR over three years, and

50% on the annual KPI scorecard performance in 2024.

We have inalised our annual KPI scorecard for 2024 with a

focus on safety, inancial performance, production, business

plan implementation, embedding sustainability, unlocking

value and leadership eectiveness. We believe all targets to

be suitably challenging.

LTIP awards will be made to Rahul Dhir and Richard Miller in

2024, and will continue to be based on 50% of relative TSR and

50% of absolute TSR performance assessed over the three

years from 1 January 2024. Details can be found on pages 101

and 102.

Remunerton rrnements for the

#### wderworforce

During 2023 the Committee continued to consider the

alignment of remuneration arrangements through the

workforce, ensuring all employees are rewarded fairly

andconsistently for their contribution to the overall

Company performance. In doing so, the Committee took

into account the presentations made to the Board on the

Company’s initiatives regarding culture and the Employee

Value Proposition.

#### Emploee enement

During the year, members of the Committee met with the

workforce Tullow Advisory Panel (TAP), a sta panel, which

collectively represents Tullow’s global workforce. These

meetings provided an opportunity to gather feedback

from employees to help shape decisions with regards to

the ongoing development of Tullow’s Employee Value

Proposition. On behalf of the Committee I would like to

thank TAP members and other employees for their input to

the Board’s discussions.

#### Revew of Commttee effectveness

The Committee undertook a review of its eectiveness in

2024, in respect of the year ended 31 December 2023, with

the results reported to the Board (see pages 77 and 78). I am

operating eectively and in accordance with the Code and

relevant guidance. The feedback provided has been used to

Determnton of 2024 TIP nd Annul Bonus Awrds bsed on performnce to 31 December 2023 (udted)

We measure performance using a corporate scorecard that includes a number of inancial and non-inancial key

performance indicators (KPIs). The corporate scorecard is central to Tullow’s approach to performance management and

the 2023 metrics were agreed with the Board and focus on targets that were deemed important for the year. Each KPI

measured has a percentage weighting and inancial indicators have trigger, base, and stretch performance targets.

For the Executive Directors participating in TIP, an additional TSR metric was included, which represents a weighting of

50% of the total corporate scorecard.

Progress against the corporate scorecard is tracked during the year to assess performance against strategy. Following

the end of the 2023 inancial year, the corporate scorecard performance was assessed as 53% of the maximum for

Annual Bonus Award and the workforce and 26.5% for the Executive Directors participating in TIP taking into account

the additional TSR metric. The Committee is satisied with the outcome based on the broader view of performance and

stakeholder experience.

Deferral of activity in our Gabon non-operated business and

suspension of the Mauritania decommissioning operations was

replaced by accelerated Jubilee drilling.

The capex programme was delivered in line with Budget, however the

suspension of decommissioning operations in Mauritania and restart

in 2024 will result in a cost increase and this is relected in the 33%

Sustainability

across the

organisation

In 2023, we progressed our Net Zero plan including ongoing

implementation of our decarbonisation initiatives on Jubilee and TEN

and together with the Ghana Forestry Commission, engaging with

various stakeholders and conducting ield mapping work on a nature-

based project which is progressing to inal investment decisions.

During the year, we completed a macro socio-economic impact

assessment of our activities in Ghana to calculate the extent of our

contribution to advancing the Ghanaian economy and improving

life for the people in Ghana; this is core to our purpose of building a

better future through responsible oil and gas development. We also

continued our focus on enhancing employability through supporting

education and enterprise. Working with our partners in Ghana, Kenya,

Guyana and Suriname we enabled more than 10,000 students to

access education and supported more than 150 teachers in training.

During the year, we made progress in all aspects of optimising local

content, including increasing spend with indigenous suppliers;

enhancing supplier education; developing supplier capacity and

monitoring supplier social and economic impact. We also refreshed

our brand and our values, with the aim of creating an inclusive,

transparent, performance-driven organisation where our people are

empowered and energised to bring their best selves to work. The

above performance delivered overall in accordance with the base

target set and provides a solid foundation to build on in the future.

Therefore, a score of 4.2% out of a possible 5% was deemed as

reasonable.

Leadership

eectiveness

The Board made a judgement on the performance of the SLT over

the year. They considered several factors, including the strength and

cohesiveness of the leadership team, a clear strategy being set and

understood across the organisation, a fully engaged workforce, and

the business being positioned for sustainable success. During 2023

the leadership team has strengthened and, supported by the hard

work and dedication of the entire Tullow team, has worked together

cohesively to ensure continued operational delivery through an

unrelenting focus on business performance. The leadership team

also progressed activities to position the organisation for future

sustainable success by unlocking value in the identiied critical areas.

This resulted in a score of 3.75%.

Comprson of overll performnce nd p

The Committee has chosen to compare the TSR of the Company’s ordinary shares against the FTSE 250 index; whilst the

Company was placed outside the index for the majority of 2023, we believe the size and complexity of the organisation

still makes this a comparable index. The values indicated in the graph above show the share price growth plus re-invested

dividends for the period 2014 to 2023 from a £100 hypothetical holding of ordinary shares in Tullow Oil plc and in the index.

The total remuneration igures for the CEO during each of the last 10 inancial years are shown in the tables below. The

total remuneration igure includes the annual bonus based on that year’s performance (2014 to 2023), TIP Awards based

on the performance period ending in the relevant year (2014 to 2023). The annual bonus payout and TIP Award, as a

percentage of the maximum opportunity, are also shown for each of these years.

We have calculated the CEO pay ratio using the methodology described as ‘Option A’ in the Regulations, as we recognise

that this is the most statistically accurate form of calculation.

For each UK employee¹ the Single Total Figure of Remuneration (STFR) has been calculated as a summation of base pay,

beneits, employer pension contributions receivable during the year ended 31 December 2023 and cash bonus payable

and value of share awards to be granted for the 2023 performance year. The STFR at 25th percentile is £121,044, £178,373

at median and £249,630 at 75th percentile. The wages component at 25th percentile is £87,331, £167,800 at median and

£156,663 at 75th percentile.

#### Annul Report on Remunerton contnued

CEO p rto 2023 contnued

In setting both our CEO remuneration and the remuneration structures for the wider UK workforce, we have adopted a

remuneration structure which includes the same core components for employees at all levels (base pay, beneits, pension,

cash bonus and share awards). Whilst all employees receive a base salary commensurate to the Company’s position in the

market, the dierences exist in the quantum of variable pay achievable by our Executive Directors and SLT; at these levels

there is a greater emphasis placed on variable pay given their opportunity to impact directly on Company performance.

Based on this distinction, and taking into account Company performance in a particular inancial year and the impact on

variable pay, the Committee believes that the median pay ratio is consistent with and relective of the wider pay, reward and

progression policies impacting our UK employees. The Committee will continue to monitor longer-term trends.

Reltve mportnce of spend on p

The following table shows the Group’s actual spend on pay for all employees relative to tax and retained proits.

Sta costs have been compared to tax expense and retained proits in order to provide a measure of their scale

Prncples of Executve Drector remunerton

The Committee seeks to ensure that the Directors Remuneration Policy and its practices are consistent with the six

factors set out in Provision 40 of the new UK Corporate Governance Code:

Clarity

Our Policy is well understood by the SLT and has been clearly articulated to our shareholders and representative bodies

(both on an ongoing basis and during the recent consultation exercise).

Simplicity

The Committee is mindful of the need to avoid overly complex remuneration structures which can be misunderstood and

deliver unintended outcomes. Therefore, a key objective of the Committee is to ensure that our Executive remuneration

policies and practices are straightforward to communicate and operate.

Risk

Our Policy has been designed to ensure that inappropriate risk taking is discouraged and will not be rewarded via: (i)

the balanced use of both annual and three-year performance periods which employ a blend of inancial, non-inancial

and shareholder return targets; (ii) the signiicant role played by deferred equity in our incentive plans (together with in-

employment and post-cessation shareholding guidelines and ive-year vesting period); (iii) malus/clawback provisions;

and (iv) the ability to exercise negative discretion to remuneration outcomes.

Predictability

The TIP and Annual Bonus and LTIP are subject to an individual annual cap and market-standard dilution limits.

Proportionality

There is a clear link between individual awards, delivery of strategy and our long-term performance. In addition, the

signiicant role played by incentive/‘at-risk’ pay, together with the structure of the Executive Directors’ service contracts,

ensures that poor performance is not rewarded.

Alignment to culture

Our Executive pay policies are fully aligned to Tullow’s culture through the use of metrics in the TIP, LTIP and Annual

Bonus Plan that measure how we perform against our inancial and non-inancial KPIs.

#### Drectors’ Remunerton Polc Report

This section of the report sets out the Remuneration Policy

(the Policy) for Executive and Non-Executive Directors which

was approved by shareholders at the 2023 AGM on 24 May

2023. The Policy has come into eect from the date of the

AGM and will apply for a period of up to three years.

Polc overvew

The principles of the Remuneration Committee are to

ensure that remuneration is linked to Tullow’s strategy

and promote the attraction, motivation and retention of

the highest-quality executives who are key to delivering

sustainable long-term value growth and substantial returns

to shareholders.

Polc revew process

The Committee undertook a review of Directors’

Remuneration Policy to ensure that it is appropriate to

support our strategy. The central focus of the Committee

was developing an incentive structure that would reward

growth and value creation and align management

withshareholders.

The Committee was mindful in its deliberations on the

new Remuneration Policy of any potential conlicts of

interest and sought to minimise them through an open

and transparent internal consultation process, by seeking

independent advice from its external advisers and by

undertaking a broad shareholder consultation exercise.

2023 Polc chnes

The main change under the Policy is the transition from the

Tullow Incentive Plan to the grant of separate annual bonus

and LTIP awards. This transition is structured to ensure that

there are no overlaps or gaps in performance assessment

for Executive Directors appointed prior to 2023.

For the current CEO the TIP will continue for 2024

(capturing 2022–2024 performance period) in accordance

with the structure approved by shareholders at the 2020

AGM. No TIP awards will be made after 2024. Other

Executive Directors will not participate in the TIP for 2024.

Executive Directors appointed from 2023 onwards,

including the current CFO, are eligible for an annual bonus

award from 2023 onwards. Our current CEO will be eligible

for an annual bonus award from 2025 onwards. The

maximum opportunity will be 150% of salary and one-third

of any bonus earned will normally be deferred into Tullow

shares for three years.

All Executive Directors are eligible for an LTIP award from

2023 onwards. The irst grant captured performance over

the 2023–2025 period. The maximum award will be 250%

of salary, and awards will be subject to a two-year holding

period following vesting.

The policy was also updated for developments in corporate

governance and feedback received from our shareholders.

Generally reviewed annually. Base salaries will be set by

the Committee taking into account:

•  The scale, scope and responsibility of therole.

•  The skills and experience of the individual.

•  The base salary of other employees, including

increases awarded to the wider population.

•  The base salary of individuals undertaking similar

roles in companies of comparable size and

complexity. This may include international oil and gas

sector companies or a broader group of FTSE-listed

organisations.

Any increases to current Executive

Director salaries, presented in the

‘Application of Policy in 2024’ column

below this Policy table, will not normally

exceed the average increase awarded to

other UK-based employees.

Increases may be above this level in

certain circumstances, for instance

if there is an increase in the scale,

scope or responsibility of the role

or to allow the base salary of newly

appointed Executives to move towards

market norms as their experience and

contribution increase.

Performance and provisions for the recovery

A broad assessment of individual and business performance is used as part of the salary review.

No recovery provisions apply.

The current CEO is eligible to receive a TIP award,

subject to performance, for 2023 (for the 2021–23

period) and 2024 (for the 2022–24 period). No further

TIP awards will be granted after 2024, and any Executive

Any amount above 200% of base salary is awarded

entirely in deferred shares.

Deferred shares are normally subject to deferral until the

ifth anniversary of grant, normally subject to continued

service.

TIP awards are non-pensionable and will be made in line

with the Committee’s assessment of performance targets.

At the discretion of the Committee, any portion of the

cash component of a TIP award can be satisied by

granting deferred shares with a vesting date set by the

Committee being not earlier than the irst anniversary

ofgrant.

400% of salary.

Dividend equivalents will accrue on TIP

deferred shares over the vesting period.

Performance and provisions for the recovery

A balanced scorecard of stretching inancial and operational objectives, linked to the achievement of Tullow’s long-term strategy, will

be used to assess TIP outcomes which may include targets relating to: relative or absolute total shareholder return (TSR); earnings per

share (EPS); environmental, health and safety (EHS); inancial; production; operations; project; exploration; or speciic strategic and

personal objectives.

Performance will typically be measured over one year for all measures apart from TSR and EPS, which, if adopted, will normally be

measured over the three inancial years prior to grant.

No more than 25% of the maximum TIP opportunity will be payable for threshold performance.

Recovery provisions apply (see below).

Purpose and link to strategy Operation Maximum opportunity

The executive bonus scheme

rewards Executive Directors for

achieving inancial and strategic

targets in the relevant year by

reference to operational targets

and individual objectives.

The Current CEO will be eligible to participate in the

Annual Bonus plan from 2025 onwards.

The current CFO and any newly appointed Executive

Directors are eligible to participate from 2023 onwards.

Targets are reviewed annually and any pay-out is

determined by the Committee after the year end based

on targets set for the inancial period.

The Committee has discretion to amend the pay-out

should any formulaic output not relect the Committee’s

assessment of overall business performance or if the

Committee considers the formulaic outturn is not

appropriate in the context of other factors considered by

the Committee to be relevant.

One-third of any bonus earned will normally be deferred

into shares for a period of three years. Deferred bonus

awards may take the form of nil-cost options, conditional

awards of shares or such other form as has a similar

economic eect.

Additional shares may be delivered in respect of shares

subject to deferred bonus awards to relect the value of

dividends paid during the period beginning with the date

of grant and ending with the date of vesting (this payment

may assume that dividends had been reinvested in Tullow

shares on a cumulative basis).

Up to 150% of salary.

Performance and provisions for the recovery

A balanced scorecard of stretching inancial and operational objectives, linked to the achievement of Tullow’s long-term strategy, will

be used to assess Annual Bonus outcomes. Performance will typically be measured over one year.

No more than 25% of the maximum opportunity will be payable for threshold performance.

Recovery provisions apply (see below).

Lon Term Incentve Pln (LTIP)

Purpose and link to strategy Operation Maximum opportunity

The LTIP provides a clear link

between the remuneration of

the Executive Directors and the

creation of value for shareholders

by rewarding the Executive

Directors for the achievement of

longer-term objectives aligned to

shareholders’ interests.

Executive Directors will be eligible to be granted LTIP

award from 2023 onwards.

Awards are normally made on an annual basis and

normally vest three years from grant subject to continued

employment and the satisfaction of challenging three-

year performance targets.

A two-year holding period following LTIP vesting applies

to grants to Executive Directors. In total, this results in a

ive-year combined vesting and holding period.

The Committee has discretion to vary the formulaic

vesting outturn if it considers that the outturn does not

relect the Committee’s assessment of performance or is

not appropriate in the context of other factors considered

by the Committee to be relevant.

Additional shares may be delivered in respect of

shares which vest under the LTIP to relect the value of

dividends, which would have been paid on those shares

during the period beginning with the date of grant and

ending with the vesting date (this payment may assume

that dividends had been reinvested in Tullow shares on a

cumulative basis).

Up to 250% of salary.

Performance and provisions for the recovery

Performance is usually measured over a three-year period.

Performance measures for LTIP awards will include inancial measures which may include, but are not limited to, total shareholder

return (TSR), and may include strategic measures (which may include ESG measures).

Subject to the Committee’s discretion to override formulaic outturns, awards will normally vest as to 25% for threshold performance,

increasing to 100% for maximum performance.

Recovery provisions apply (see below).

Purpose and link to strategy Operation Maximum opportunity

To align the interests of

management and shareholders

and promote a long-term

approach to performance and

riskmanagement.

Executive Directors are required to retain at least 100%

of post-tax share awards until a minimum shareholding

equivalent to 400% of base salary is achieved in

ownedshares.

Unvested TIP, LTIP and Deferred Bonus shares net

of applicable taxes count towards the minimum

shareholding requirement.

Shares included in this calculation are those held

post-cessation.

400% of salary.

Performance and provisions for the recovery

Not applicable.

Non-Executve Drectors

Purpose and link to strategy Operation Maximum opportunity

To provide an appropriate fee level.

To attract individuals with the

necessary experience and ability.

To make a signiicant contribution

to the Group’s activities while also

relecting the time commitment

and responsibility of the role.

The Chair is paid an annual fee and the Non-Executive

Directors are paid a base fee and additional responsibility

fees, for example for the role of Senior Independent

Director or for chairing a Board Committee.

Fees are normally reviewed annually.

Each Non-Executive Director is also entitled to a

reimbursement of necessary travel and other expenses

including associated tax costs.

Non-Executive Directors do not participate in any share

scheme or annual bonus scheme and are not eligible to

join the Group’s pension schemes.

Non-Executive Director remuneration is

determined within the limits set by the

Articles of Association.

There is no maximum prescribed fee

increase although fee increases for

Non-Executive Directors will not normally

exceed the average increase awarded

to Executive Directors. Increases may be

above this level if there is an increase in the

scale, scope or responsibility of the role.

Performance and provisions for the recovery

Not applicable.

Operton of shre plns

The Committee will operate the TIP, LTIP and Deferred Bonus in accordance with the Plan rules, Listing Rules and HMRC

rules where relevant. The Committee, consistent with market practice, retains discretion over a number of areas relating

to the operation and administration of the plans in relation to the SLT, including Executive Directors. These include (but

are not limited to) the following (albeit with the level of award restricted as set out in the Directors’ Remuneration Policy):

•  Who participates.

•  The timing of grant of awards and/or payment.

•  The size of awards and/or payment.

•  Discretion relating to the measurement of performance in the event of a change of control or reconstruction.

•  Determination of a good leaver (in addition to any speciied categories) for incentive plan purposes and a good

leaver’streatment.

•  Adjustments to awards required in certain circumstances (e.g. rights issues, corporate restructuring and special dividends).

•  The ability to adjust existing performance conditions for exceptional events so that they can still fulil their

original purpose.

The choice of the performance metrics applicable to the TIP and LTIP awards, which are set by the Committee at the start

of the relevant inancial year, relects the Committee’s belief that any incentive compensation should be appropriately

challenging and tied to the delivery of stretching inancial, operational and TSR-related objectives, explicitly linked to the

achievement of Tullow’s long-term strategy.

In addition to the TIP, LTIP and Deferred Bonus, Executive Directors are also eligible to participate in the UK SIP or

any other all-employee share plans on the same terms as other employees. All-employee share plans do not operate

performance conditions.

Clculton of TIP wrds

In addition to base salary and other beneits described in the Remuneration Policy, for 2023 and 2024 Executive Directors

shall be eligible to receive an award issued under the rules of the TIP (a TIP Award). The TIP combines short- and long-

term incentive-based pay and includes a cash bonus component and a deferred share award component.

At the beginning of the 2023 and 2024 inancial years, the Committee will determine a multiple of base salary, subject

to the limits established under this Policy, to apply to a TIP Award. At the same time the Committee will also determine

a balanced corporate scorecard of performance metrics applicable to any TIP Award. The choice of the performance

metrics and the weightings given to them, which are set by the Committee at the start of the relevant inancial year

normally, relect the Committee’s belief that any incentive compensation should be appropriately challenging and tied to

the delivery of stretching inancial, operational and total shareholder return (TSR) related objectives, explicitly linked to the

achievement of Tullow’s long-term strategy.

Following completion of the inancial year, the Committee will review the Company’s performance against the corporate

scorecard resulting in a percentage score. The multiple set by the Committee is then applied to the percentage score to

determine the total TIP Award amount. A TIP Award is divided equally between cash bonus and deferred shares up to the

irst 200% of base salary. Any portion of a TIP Award above 200% of base salary shall be satisied in deferred shares only.

Deferred shares forming part of a TIP Award are normally deferred for ive years and are subject to malus and clawback. In

its discretion, the Committee may elect to satisfy any portion of the cash bonus element of a TIP Award in deferred shares

which will be deferred for a period determined by the Committee, being not less than one year from the date of grant.

Deferred shares issued in lieu of any portion of the cash bonus component of a TIP Award shall be subject to malus,

clawback and the minimum shareholding requirements set out on the previous page.

Performnce mesures for LTIP nd nnul bonus wrds

The choice of the performance metrics and range of targets applicable to the annual bonus plan for Executive Directors

relect the Committee’s belief that any incentive compensation should be appropriately challenging and tied to both

the delivery of robust performance relating to the Group’s inancial key performance indicators and, where appropriate,

speciic individual/strategic objectives (including ESG objectives). Performance metrics applicable to the LTIP are

selected to support Company strategy and provide shareholder alignment. Targets applying to the annual bonus and

LTIP are reviewed annually, based on a range of internal and external reference points. Performance targets are set to be

stretching but achievable, with regard to the particular strategic priorities and business environment in a given year.

Lec remunerton

For the avoidance of doubt, the Committee reserves the right to make any remuneration payments and/or payments for

loss of oice (including exercising any discretions available to it in connection with such payments) notwithstanding that

they are not in line with the 2023 Remuneration Policy set out in the document where the terms of the payment were

agreed (i) before the 2023 Remuneration Policy came into eect, provided that the terms of the payment were consistent

with any applicable shareholder-approved Directors’ Remuneration Policy in force at the time they were agreed or were

otherwise approved by shareholders; or (ii) at a time when the relevant individual was not a Director of the Company (or

other persons to whom the Policy set out above applies) and, in the opinion of the Committee, the payment was not in

consideration for the individual becoming a Director of the Company or such other person.

For these purposes ‘payments’ includes the Committee satisfying awards of variable remuneration and, in relation to an

award over shares, the terms of the payment are ‘agreed’ no later than the time the award is granted. This Policy applies

equally to any individual who is required to be treated as a Director under the applicable regulations.

Dscreton

The Committee reserves the right to exercise its discretion in the event of exceptional and unforeseen positive or

negative developments during the performance period. In addition, the Committee reserves the right to reduce the

TIP, annual bonus or LTIP payment where the Committee considers that the level of payment is not commensurate with

overall corporate performance and returns delivered to shareholders over the performance period.

The charts below show how the composition of the Executive Directors’ remuneration packages varies at dierent levels

of performance under the Remuneration Policy, as a percentage of total remuneration opportunity and as a total value for

the current CEO and CFO for 2024.

1.  Base salary is eective as at 1 April 2024.

2.  Fixed pay includes pension in line with wider workforce.

3.  For the CEO, the target TIP Award is taken to be 50% of the maximum annual opportunity for 2024 (200% of salary).The maximum value of the TIP is

taken to be 400% of salary (i.e. the maximum annual opportunity) for 2024.

4.  For the CFO, the target Annual Bonus and LTIP Award is taken to be 50% of the maximum opportunity for 2024 (Annual Bonus: 75% of salary; LTIP

Award: 125% of salary). The maximum value of the Annual Bonus is taken to be 150% and LTIP Award is taken to be 250% of salary (i.e. the maximum

annual opportunity).

5.  No share price appreciation has been assumed for the ixed, target and maximum scenarios.

6.  The Committee is aware of the regulations requiring an indication of the impact of 50% share price appreciation on the maximum scenario in the chart

above. For the TIP, given that TSR performance is measured over three years prior to grant of award, share price appreciation over the performance

period would not impact on the value of the maximum award.

Servce reements

Executive Director service agreements set out restrictions on the ability of the Director to participate in businesses

competing with those of the Group or to entice or solicit away from the Group any senior employees in the six months after

ceasing employment. The above relects the Committee’s policy that service contracts should be structured to relect the

interests of the Group and the individuals concerned, while also taking due account of market and best practice.

The term of each service contract is not ixed. Each agreement is terminable by the Director on six months’ notice and by

the employing company on 12 months’ notice.

The Executive Directors’ service agreements and the appointment letters of the Non-Executive Directors are available for

inspection by shareholders at the Company’s registered oice.

Externl ppontments

The Board operates a formal policy in relation to the external directorships that an Executive Director may hold. Whilst the

policy does not prescribe a maximum number of external appointments, it sets out guidance that an Executive Director

should not hold more than one non-executive director position in a FTSE 350 company.

Polc for new ppontments

The remuneration of a new Executive Director will normally include salary, beneits, pension and participation in the

annual bonus and LTIP arrangements in accordance with the policy for Executive Directors’ remuneration. A newly

appointed Executive Director would not participate in the TIP. In addition, the Committee has discretion to include any

other remuneration component or award which it feels is appropriate taking into account the speciic circumstances of

the recruitment, subject to the principles and limits set out below. The key terms and rationale for any such component

would be disclosed as appropriate in the Directors’ Remuneration report for the relevant year.

Policy

Salary Salary will be set taking into account the individual’s experience and skills, prevailing market rates in

companies of comparable size and complexity and internal relativities.

Where appropriate, the Committee may set the initial salary below the market level (e.g. if the

individual has limited PLC board experience or is new to the role), with the intention to make phased

pay increases over a number of years, which may be above those of the wider workforce, to achieve

the desired market positioning. These increases will be subject to continued development in the role.

Buy-out

awards

Where an individual forfeits outstanding variable pay opportunities or contractual rights at a previous

employer as a result of appointment, the Committee may oer compensatory payments or awards, in

such form as the Committee considers appropriate, taking into account all relevant factors including

the form of awards, expected value and vesting time frame of forfeited opportunities.

When determining any such buy-out, the guiding principle would be that awards would generally be

on a like-for-like basis unless this is considered by the Committee not to be practical or appropriate.

Award may be facilitated under the existing incentive plans where possible, but also using Rule 9.4.2.

of the Listing Rules, if necessary.

Maximum

level of

variable

remuneration

The Committee will not oer non-performance-related variable remuneration and the maximum level

of variable remuneration which may be granted (excluding buyout awards) is 400% of base salary,

which is in line with the current maximum limit under the annual bonus and LTIP.

Other

elements of

remuneration

Other elements may be included in the following circumstances:

An interim appointment being made to ill an Executive Director role on a short-term basis.

If exceptional circumstances require that the Chair or a Non-Executive Director takes on an executive

function on a short-term basis.

If an Executive Director is recruited at a time in the year when it would be inappropriate to provide an

annual bonus or LTIP award for that year. Subject to the limit on variable remuneration set out above, the

quantum in respect of the period employed during the year may be transferred to the subsequent year.

If the Executive Director is required to relocate, reasonable relocation, travel and subsistence

payments may be provided (either via one-o or ongoing payments or beneits).

For an internal Executive Director appointment, any variable pay element awarded in respect of the prior role may be

allowed to pay out according to its terms, adjusted as relevant to take account of the appointment. In addition, any other

ongoing remuneration obligations existing prior to appointment may continue. For external and internal appointments,

the Committee may agree that the Company will meet certain relocation and/or incidental expenses as appropriate.

Fee levels for Non-Executive Director appointments will take into account the expected time commitment of the role and

the current fee structure in place at that time.

Polc for loss of offce

Executive Directors’ service contracts are terminable by the Director on six months’ notice and by the relevant employing

company on 12 months’ notice. There are no speciic provisions under which Executive Directors are entitled to receive

compensation upon early termination, other than in accordance with the notice period.

On termination of an Executive Director’s service contract, the Committee will take into account the departing Director’s duty

to mitigate his loss when determining the amount of any compensation. Disbursements such as legal and outplacement costs

and incidental expenses may be payable where appropriate, and payments may be made for accrued holiday.

The Committee reserves the right to make payments by way of settlement of any claim arising in connection with the

cessation of employment.

The following payments may also be made to departing Executive Directors:

Cessation of employment due to death, injury, disability, retirement (for

TIP awards only), redundancy, the participant’s employing company

orbusiness for which they work being sold out of the Company’s Group

or in other circumstances at the discretion of the Committee.

Cessation of employment due to other

reasons (e.g. termination for cause)

TIP (cash) Cessation during a inancial year, or after the year but prior

to the normal TIP Award date, may, at the discretion of the

Committee, result in the cash part of the TIP being paid

following the date of cessation (prorated for the proportion

ofthe year worked).

No entitlement to the cash part

ofthe TIP following the date notice

is served.

TIP (shares) Cessation during a inancial year, or after the year but prior

to the normal TIP Award date, may, at the discretion of the

Committee, result in an award of deferred shares being made

(prorated for the proportion of the year worked). Unvested

TIP shares generally vest at the normal vesting date (except

on death or retirement – see below) unless the Committee

determines they should vest at cessation. On death, TIP shares

generally vest immediately unless the Committee determines

that they should vest at the normal vesting date. On retirement

(as evidenced to the satisfaction of the Committee), TIP shares

will vest at the earlier of the normal vesting date and three years

from retirement unless the Committee determines they should

vest at cessation.

Unvested TIP shares lapse. No

entitlement to the deferred share

element of the TIP following the

date notice is served.

Annual bonus The Executive Director will normally be considered for

abonuspayment.

It is the Committee’s policy to ensure that any bonus payment

relects the departing Executive Director’s performance. Unless

the Committee determines otherwise, any bonus payment

will be paid at the usual time following the determination of

performance measures and be subject to a pro rata reduction

for time served during the performance period.

No entitlement to annual bonus

award following date notice is served.

Deferred

bonus shares

Unvested awards will continue and will vest at the normal

vesting date. In exceptional circumstances, the Committee may

decide that the Executive Director’s deferred share awards will

vest at the date of cessation of employment.

Unvested awards will normally

lapse on cessation of employment.

LTIP awards Unvested awards will continue and will remain capable of

vesting at the normal vesting date. To the extent that the awards

vest, a two-year holding period would then normally apply.

In exceptional circumstances, the Committee may decide that

the Executive Director’s awards will vest and be released early at

the date of cessation of employment or at some other time (e.g.

following the end of the performance period).

In either case, vesting will depend on the extent to which the

performance measures have been satisied and will be subject

to a pro rata reduction of the awards for time served from the

grant date to the date of cessation of employment (although

the Committee has discretion to disapply time prorating if the

circumstances warrant it).

Unvested awards will normally

lapse on cessation of employment.

If an Executive Director leaves

for any reason after an award has

vested but before it has been

released (i.e. during a holding

period), their award will ordinarily

continue to be released at the

normal release date.

The terms applying to any buy-out awards on cessation of employment or change of control would be determined when

the award is granted. Such terms would normally be consistent with the principles outlined above.

In the event of a change of control deferred bonus shares will vest in full. LTIP awards will vest early in the event of change

of control. The level of vesting will be determined taking into account the extent to which performance measures are

satisied at the date of the relevant event and, unless the Committee determines otherwise, awards will be prorated for

time served from the grant date to the date of the relevant event. TIP awards will be treated in line with the plan rules.

Consderton of shreholders’ vews

The Committee considers shareholder feedback received at the AGM each year and, more generally, guidance from

shareholder representative bodies. This feedback, plus any additional feedback received during any meetings from time to

time, is considered as part of the Company’s annual review of the continuing appropriateness of the Remuneration Policy.

Prior to the inalisation of this Policy the Committee consulted with all major shareholders on the proposals. This

feedback helped inform the inal Policy put forward for shareholder approval. The Committee will seek to engage directly

with major shareholders and their representative bodies should any material changes be proposed to be made to the

Remuneration Policy.

Emploment condtons elsewhere n the Group

In setting the Remuneration Policy and remuneration levels for Executive Directors, the Committee is cognisant of the

approach to rewarding employees in the Group and levels of pay increases generally. The Committee does not currently

formally consult directly with employees on the executive pay policy, but it does receive regular updates from the

Company Secretary and the Director of People and Sustainability. During the year this included updates on discussions

with the SLT on the proposed changes to the Directors’ Remuneration Policy and how these changes would apply more

widely to other employees.

#### Shreholders’ rhts

The rights and obligations of shareholders are set out

in the Company’s Articles of Association (which can be

amended by special resolution). The rights and obligations

attaching to the Company’s shares are as follows:

•  Dividend rights – holders of the Company’s shares

may, by ordinary resolution, declare dividends but

may not declare dividends in excess of the amount

recommended by the Directors. The Directors may also

pay interim dividends. No dividend may be paid other

than out of proits available for distribution. Subject

to shareholder approval, payment or satisfaction of a

dividend may be made wholly or partly by distribution of

speciic assets.

•  Voting rights – voting at any general meeting may be

conducted by a show of hands unless a poll is duly

demanded. On a show of hands every shareholder who is

present in person at a general meeting (and every proxy or

corporate representative appointed by a shareholder and

present at a general meeting) has one vote regardless of the

number of shares held by the shareholder (or represented

by the proxy or corporate representative). If a proxy has been

appointed by more than one shareholder and has been

instructed by one or more of those shareholders to vote ‘for’

the resolution and by one or more of those shareholders to

vote ‘against’ a particular resolution, the proxy shall have one

vote for and one vote against that resolution. On a poll, every

shareholder who is present in person has one vote for every

share held by that shareholder and a proxy has one vote

for every share in respect of which he has been appointed

as proxy (the deadline for exercising voting rights by proxy

is set out in the form of proxy). On a poll, a corporate

representative may exercise all the powers of the Company

that has authorised him.

•  A poll may be demanded by any of the following: (a) the

Chairman of the meeting; (b) at least ive shareholders

entitled to vote and present in person or by proxy or

represented by a duly authorised corporate representative

at the meeting; (c) any shareholder or shareholders

present in person or by proxy or represented by a duly

authorised corporate representative and holding shares

or being a representative in respect of a holder of shares

representing in the aggregate not less than one-tenth

of the total voting rights of all shareholders entitled to

attend and vote at the meeting; or (d) any shareholder

or shareholders present in person or by proxy or

represented by a duly authorised corporate representative

and holding shares or being a representative in respect

of a holder of shares conferring a right to attend and vote

at the meeting on which there have been paid up sums in

the aggregate equal to not less than one-tenth of the total

sums paid up on all the shares conferring that right.

•  Return of capital – in the event of the liquidation of the

Company, after payment of all liabilities and deductions

taking priority, the balance of assets available for distribution

will be distributed among the holders of ordinary shares

according to the amounts paid up on the shares held

by them. A liquidator may, with the authority of a special

resolution, divide among the shareholders the whole or any

part of the Company’s assets, or vest the Company’s assets

in whole or in part in trustees upon such trusts for the beneit

of shareholders, but no shareholder is compelled to accept

any property in respect of which there is a liability.

•  Control rights under employee share schemes – the

Company operates a number of employee share

schemes (see pages 97 and 107). Under some of these

arrangements, shares are held by trustees on behalf of

employees. The employees are not entitled to exercise

directly any voting or other control rights. The trustees

will generally vote in accordance with employees’

instructions and abstain where no instructions are

received. Unallocated shares are generally voted at the

discretion of the trustees.

•  Restrictions on holding securities – there are no

restrictions under the Company’s Articles of Association

or under UK law that either restrict the rights of UK

resident shareholders to hold shares or limit the rights of

non-resident or foreign shareholders to hold or vote the

Company’s ordinary shares.

There are no UK foreign exchange control restrictions on

the payment of dividends to US persons on the Company’s

ordinary shares.

#### Drectors

In accordance with the provisions of the Code, all

Directors eligible for re-election should retire at each

AGM and oer themselves for election or re-election (as

appropriate). Accordingly, all Directors will retire and seek

election or re-election at the AGM, anticipated to be held

on 16 May 2024. The Board believes that all Directors

oering themselves for election or re-election continue

to be eective and demonstrate commitment to the

role. The names and biographies of our current Directors

are included on pages 70 and 71 and the names of the

Directors that retired during the year are set out on page 5.

Details of the Directors’ interests in the ordinary shares of

the Company and in the Group’s long-term incentive and

other share option schemes are set out on page 101 in the

Directors’ Remuneration report.

#### Drectors’ ndemntes nd nsurnce cover

As at the date of this report, indemnities are in force

under which the Company has agreed to indemnify the

Directors, to the extent permitted by the Companies

Act 2006, against claims from third parties in respect

of certain liabilities arising out of, or in connection with,

the execution of their powers, duties and responsibilities

as Directors of the Company or any of its subsidiaries.

The Directors are also indemniied against the cost

of defending a criminal prosecution or a claim by the

Company, its subsidiaries or a regulator provided that

where the defence is unsuccessful the Director must

repay those defence costs. The Company also maintains

directors’ and oicers’ liability insurance cover, the level of

which is reviewed annually.

#### Powers of Drectors

The general powers of the Directors are set out in Article 104

of the Articles of Association of the Company. It provides

that the business of the Company shall be managed by the

Board which may exercise all the powers of the Company

whether relating to the management of the business of the

Company or not. This power is subject to any limitations

imposed on the Company by applicable legislation. It is also

limited by the provisions of the Articles of Association of the

Company and any directions given by special resolution of

the shareholders of the Company which are applicable on

the date that any power is exercised.

Please note the following speciic provisions relevant to

the exercise of power by the Directors:

•  Pre-emptive rights and new issues of shares – the

holders of ordinary shares have no pre-emptive rights

under the Articles of Association of the Company.

However, the ability of the Directors to cause the

Company to issue shares, securities convertible into

shares or rights to shares, otherwise than pursuant to

an employee share scheme, is restricted under the

Companies Act 2006 which provides that the directors

of a company are, with certain exceptions, unable to

allot any equity securities without express authorisation,

which may be contained in a company’s articles of

association or given by its shareholders in general

meeting, but which in either event cannot last for more

than ive years. Under the Companies Act 2006, the

Company may also not allot shares for cash (otherwise

than pursuant to an employee share scheme) without

irst making an oer on a pre-emptive basis to existing

shareholders, unless this requirement is waived by a

special resolution of the shareholders.

•  Borrowing powers – the net external borrowings of

the Group outstanding at any time shall not exceed an

amount equal to four times the aggregate of the Group’s

adjusted capital and reserves calculated in the manner

prescribed in Article 105 of the Company’s Articles of

Association, unless sanctioned by an ordinary resolution

of the Company’s shareholders.

#### Appontment nd replcement of Drectors

The Company shall appoint (disregarding Alternate

Directors) no fewer than two and no more than 15

Directors. The appointment and replacement of Directors

may be made as follows:

•  The shareholders may by ordinary resolution elect any

person who is willing to act to be a Director.

•  The Board may elect any person who is willing to act to

be a Director. Any Director so appointed shall hold oice

only until the next Annual General Meeting and shall

then be eligible for election.

•  Each Director is required in terms of the Articles of

Association to retire from oice at the third Annual

General Meeting after the Annual General Meeting at

which he or she was last elected or re-elected, although

he or she may be re-elected by ordinary resolution

if eligible and willing. However, to comply with the

principles of best corporate governance, the Board

intends that each Director will submit him or herself for

re-election on an annual basis.

•  The Company may by special resolution remove any

Director before the expiration of his or her period of

oice or may, by ordinary resolution, remove a Director

where special notice has been given and the necessary

statutory procedures are complied with.

•  There are a number of other grounds on which

a Director’s oice may cease, namely voluntary

resignation, where all the other Directors (being at least

three in number) request his or her resignation, where

he or she suers physical or mental incapacity, where

he or she is absent from meetings of the Board without

permission of the Board for six consecutive months,

becomes bankrupt or compounds with his or her

creditors or where he or she is prohibited by law from

being a Director.

#### Authort to llot new shres

At the Company’s AGM on 24 May 2023, shareholders

authorised the Directors, by way of ordinary resolution, to

allot new equity securities up to a maximum aggregate

value of £48, 228,412, being approximately one-third of the

issued share capital of the Company as at 17 April 2023.

The authority conferred at the 2023 AGM will expire at

the close of the Company’s AGM in 2024 or the close of

business on 30 June 2024 (whichever is earlier). At the

2024 AGM, shareholders will be requested to renew this

authority. Save for the allotment of shares in respect of the

Group’s employee share schemes, the Directors have no

current intention to exercise this authority.

#### Purchse of own shres

At the Company’s AGM on 24 May 2023 shareholders

authorised the Company by way of special resolution, to

make market purchases of a maximum of 144,685,380 of

the Company’s ordinary shares (being 10% of the issued

share capital of the Company) as at 17 April 2023 at certain

minimum and maximum prices speciied in the resolution.

The authority conferred at the 2023 AGM will expire at

the close of the Company’s AGM in 2024 or the close of

business on 30 June 2024 (whichever is earlier).

After careful consideration, including considering the

views expressed by shareholders, the Directors have

decided not to seek authority to make market purchases

of the Company’s own shares. Although, not anticipated,

should the Company require to make market purchases of

its own shares, a separate general meeting would be called

at which the authority to purchase the Company’s own

share would be sought from shareholders.

#### Poltcl dontons

In line with Group policy, no donations were made for

political purposes.

#### Audtor nd dsclosure of relevnt

#### udtnformton

Having made the requisite enquiries, so far as the Directors

are aware, there is no relevant audit information (as deined

by section 418(3) of the Companies Act 2006) of which the

Company’s auditor is unaware and each Director has taken

allsteps that ought to have been taken to make him or herself

aware of any relevant audit information and to establish that

the Company’s auditor is aware of that information.

A resolution to re-appoint EY as the Company’s auditor will

be proposed at the 2024 AGM on 16 May 2024. Further

information can be found in the Audit Committee Report

on pages 85.

#### Sttement of Drectors’ responsbltes

The Directors are responsible for preparing the Annual

Report and the Financial Statements in accordance with

applicable United Kingdom law and regulations.

Company law requires the Directors to prepare Financial

Statements for each inancial year. Under that law the

Directors have elected to prepare the Group and Parent

Company inancial statements in accordance with UK-

adopted international accounting standards (IFRSs), and the

Parent Company inancial statements in accordance with

United Kingdom Generally Accepted Accounting Practice

(United Kingdom Accounting Standards and applicable

law), including Financial Reporting Standard 101 Reduced

Disclosure Framework (FRS 101). Under company law the

Directors must not approve the Financial Statements unless

they are satisied that they give a true and fair view of the

state of aairs of the Group and the Company and of the

proit or loss of the Group and the Company for that period.

Under the Financial Conduct Authority’s Disclosure

Guidance and Transparency Rules and the Transparency

(Directive 2004/109/EC) Regulations 207 (as amended),

Group Financial Statements are required to be prepared

in accordance with UK-adopted international accounting

standards and international Financial Reporting Standards

adopted pursuant to Regulation (EC) No. 1606/2002 as it

applies in the European Union.

In preparing these Financial Statements the Directors are

required to:

•  select suitable accounting policies in accordance with

IAS 8 Accounting Policies, Changes in Accounting

Estimates and Errors and then apply them consistently;

•  make judgements and accounting estimates that are

reasonable and prudent;

•  present information, including accounting policies, in a

manner that provides relevant, reliable, comparable and

understandable information;

•  provide additional disclosures when compliance with the

speciic requirements in IFRSs and in respect of the Parent

Company Financial Statements, FRS 101 is insuicient

to enable users to understand the impact of particular

transactions, other events and conditions on the Group

and Company inancial position and inancial performance;

•  in respect of the Group Financial Statements, state

whether UK-adopted international accounting standards

and IFRSs adopted pursuant to Regulation (EC) No.

1606/2002 as it applies in the European Union have

been followed, subject to any material departures

disclosed and explained in the Financial Statements;

•  in respect of the Parent Company Financial Statements,

state whether applicable UK Accounting Standards,

including FRS 101, have been followed, subject to any

material departures disclosed and explained in the

Financial Statements; and

•  prepare the Financial Statements on the going concern

basis unless it is inappropriate to presume that the

Company and/or the Group will continue in business.

The Directors are responsible for keeping adequate

accounting records that are suicient to show and explain

the Company’s and Group’s transactions and disclose with

reasonable accuracy at any time the inancial position of

the Company and the Group and enable them to ensure

that the Company and the Group Financial Statements

comply with the Companies Act 2006. They are also

responsible for safeguarding the assets of the Group

and Parent Company and hence for taking reasonable

steps for the prevention and detection of fraud and

otherirregularities.

Under applicable law and regulations, the Directors are

also responsible for preparing a strategic report, Directors’

report, Directors’ remuneration report and corporate

governance statement that comply with that law and

those regulations. The Directors are responsible for the

maintenance and integrity of the corporate and inancial

information included on the Company’s website.

The Directors conirm, to the best of their knowledge:

•  that the consolidated Financial Statements, prepared in

accordance with UK-adopted international accounting

standards and IFRSs adopted pursuant to Regulation

(EC) No. 1606/2002 as it applies in the European Union;

•  give a true and fair view of the assets, liabilities,

inancial position and proit of the Parent Company

and undertakings included in the consolidation taken

as a whole;

•  that the Annual Report, including the Strategic

Report, includes a fair review of the development

and performance of the business and the position

of the Company and undertakings included in the

consolidation taken as a whole, together with a

description of the principal risks and uncertainties that

they face; and

•  that they consider the Annual Report, taken as a whole,

is fair, balanced and understandable and provides the

information necessary for shareholders to assess the

Company’s position, performance, business model

and strategy.

Opnon

In our opinion:

•  Tullow Oil plc’s group inancial statements and parent company inancial statements (the “inancial statements”) give

a true and fair view of the state of the group’s and of the parent company’s aairs as at 31 December 2023 and of the

group’s loss for the year then ended;

•  the group inancial statements have been properly prepared in accordance with UK adopted international accounting

standards and International Financial Reporting Standards adopted pursuant to Regulation (EC) No. 1606/2002 as it

applies in the European Union;

•  the parent company inancial statements have been properly prepared in accordance with United Kingdom Generally

Accepted Accounting Practice; and

•  the inancial statements have been prepared in accordance with the requirements of the Companies Act 2006.

We have audited the inancial statements of Tullow Oil plc (the ‘parent company’) and its subsidiaries (the ‘group’) for the

year ended 31 December 2023 which comprise:

Group Parent company

Group balance sheet as at 31 December 2023 Company balance sheet as at 31 December 2023

Group income statement for the year then ended Company statement of changes in equity for the year

then ended

Group statement of comprehensive income for the

Related notes 1 to 7 to the inancial statements including

material accounting policy information

Group statement of changes in equity for the year then ended

Group cash low statement for the year then ended

Related notes 1 to 30 to the inancial statements, including

material accounting policy information.

The inancial reporting framework that has been applied in the preparation of the group inancial statements is applicable

law and UK adopted international accounting standards and International Financial Reporting Standards adopted

pursuant to Regulation (EC) No. 1606/2002 as it applies in the European Union. The inancial reporting framework that

has been applied in the preparation of the parent company inancial statements is applicable law and United Kingdom

Accounting Standards, including FRS 101 “Reduced Disclosure Framework” (United Kingdom Generally Accepted

Accounting Practice).

#### Bss for opnon

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our

responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the inancial

statements section of our report. We believe that the audit evidence we have obtained is suicient and appropriate to

provide a basis for our opinion.

#### Independence

We are independent of the group and parent in accordance with the ethical requirements that are relevant to our audit of

the inancial statements in the UK, including the FRC’s Ethical Standard as applied to listed public interest entities, and we

have fulilled our other ethical responsibilities in accordance with these requirements.

The non-audit services prohibited by the FRC’s Ethical Standard were not provided to the group or the parent company

and we remain independent of the group and the parent company in conducting the audit.

#### Conclusons reltn to on concern

In auditing the inancial statements, we have concluded

that the directors’ use of the going concern basis of

accounting in the preparation of the inancial statements

is appropriate. Our evaluation of the directors’ assessment

of the group and parent company’s ability to continue to

adopt the going concern basis of accounting included:

•  evaluating whether management’s going concern

period, of 12 months from signing of the inancial

statements, was appropriate;

•  assessing the reasonableness of management’s oil price

assumptions by comparing it with forward curves;

•  with the assistance of our business modelling

specialists, reviewing the integrity of management’s

going concern model by checking consistency of the

assumptions and formulae;

•  comparing the forecasted cash expenditure

incorporated in the model with the board approved

budget to ensure consistency;

•  assessing historical forecasting accuracy through

comparing forecast versus actual;

•  checking that the cash lows assumptions used in

the going concern model were consistent with those

used for impairment testing purposes, including

decarbonisation costs, and evaluating the dierences for

appropriateness;

•  ensuring assumptions, such as hedging, provision

utilisation and decommissioning escrow payments, were

consistent with other areas of our audit;

•  assessing whether the assumptions in the

management’s downside scenario were plausible and

suiciently severe;

•  verifying managements plan in relation to repayment of

the remaining outstanding 2025 bonds and assessing

whether there is suicient liquidity at the end of going

concern period, after their repayment;

•  obtaining an understanding of ongoing litigations and

identifying cases, in particular those mentioned in

the accounting policies note section (af), where the

outcome is expected within the going concern period.

We then evaluated whether management’s downside

case suiciently captured potential outlows in relation

to these cases;

•  evaluating management’s reverse stress test to

determine the oil price at which liquidity becomes

negative and assessing the likelihood of its occurrence;

•  conirming that the forecast decarbonisation costs were

included in the model; and

•  reviewing management’s proposed disclosures to

ensure that they were appropriate and met current

accounting requirements.

#### Our e observtons

In forming our conclusions, we have considered the

generation of free cash low and available liquidity that

supports the repayment of 2025 bonds. With maturities of

the 2026 bonds in May 2026 and tax arbitration hearings

scheduled for 2025, we consider the management’s

going concern period of 12 months to be reasonable.

We consider the downside case is suiciently severe

and appropriately relects potential outlows in respect

of ongoing arbitrations. Under management’s reverse

stress test, at an oil price of $45/bbl throughout the going

concern period, the liquidity becomes negative. Based on

the current oil price and forward curve we consider the

likelihood of occurrence of this scenario to be remote.

Based on the work we have performed, we have not

identiied any material uncertainties relating to events

or conditions that, individually or collectively, may cast

signiicant doubt on the group and parent company’s

ability to continue as a going concern for a period up to

March 2025.

In relation to the group and parent company’s reporting

on how they have applied the UK Corporate Governance

Code, we have nothing material to add or draw attention

to in relation to the directors’ statement in the inancial

statements about whether the directors considered

it appropriate to adopt the going concern basis of

accounting.

Our responsibilities and the responsibilities of the

directors with respect to going concern are described

in the relevant sections of this report. However, because

not all future events or conditions can be predicted, this

statement is not a guarantee as to the group’s ability to

continue as a going concern.

account size, risk proile, the organisation of the group

and eectiveness of group-wide controls, changes in the

business environment, the potential impact of climate

change and other factors such as recent Internal audit

results when assessing the level of work to be performed

at each company.

In assessing the risk of material misstatement to the Group

inancial statements, and to ensure we had adequate

quantitative coverage of signiicant accounts in the

inancial statements, of the 41 reporting components of

the Group, we selected 11 components covering entities

within Cote D’Ivoire, Gabon, Ghana, Kenya and the United

Kingdom, which represent the principal business units

within the Group.

Of the 11 components selected, we performed an audit

of the complete inancial information of 4 components

(“full scope components”) which were selected based

on their size or risk characteristics. For the remaining

7 components (“speciic scope components”), we

performed audit procedures on speciic accounts within

that component that we considered had the potential

for the greatest impact on the signiicant accounts in the

inancial statements either because of the size of these

accounts or their risk proile.

The reporting components where we performed full or

speciic audit procedures accounted for 101% (2022: 97%)

of the Group’s Adjusted EBITDAX, 100% (2022: 97%) of the

Group’s Revenue and 90% (2022: 90%) of the Group’s Total

assets. For the current year, the full scope components

contributed 104% (2022: 103%) of the Group’s Adjusted

EBITDAX, 98% (2022: 99%) of the Group’s Revenue and

83% (2022: 83%) of the Group’s Total assets. The speciic

scope components contributed -3% (2022: -6%) of the

Group’s Adjusted EBITDAX, 2% (2022: -2%) of the Group’s

Revenue and 7% (2022: 7%) of the Group’s Total assets. The

audit scope of these components may not have included

testing of all signiicant accounts of the component

but will have contributed to the coverage of signiicant

accounts tested for the Group. We also performed

speciied procedures over certain aspects of Cash and

Cash Equivalents and Finance Revenue in one location.

Of the remaining 30 components that together represent

0% of the Group’s Adjusted EBITDAX, none are individually

greater than 1% of the Group’s Adjusted EBITDAX. For

these components, we performed other procedures,

including analytical review, testing of consolidation

journals and intercompany eliminations to respond to

any potential risks of material misstatement to the Group

inancial statements.

#### Chnes from the pror er

There were no changes to our full scope components in

the current year. For other scopes, we have updated our

assessment this year to exclude three exploration entities

that are no longer material, primarily due to exploration

cost write-os in 2022. These changes had limited impact

on coverage.

In line with our approach from the previous year, audit

work for the Ghana component, which covers 2 full scope

components, has been performed by an integrated

primary audit team comprising of team members from EY

UK and EY Ghana and led by the Senior Statutory Auditor.

During the current year’s audit cycle, visits were

undertaken by the Group audit team to Ghana in July

2023, November 2023 and January 2024. These visits

involved meetings with local management, including

members of inance, legal and commercial teams. We

held discussions on the audit approach, reviewed working

papers to validate that the required procedures have

been performed and discussed the issues arising in the

component audit.

All audit work performed for the purposes of the audit was

undertaken by the Group audit team.

Clmte chne

Stakeholders are increasingly interested in how climate

change will impact Tullow Oil Plc. The Group has

determined that the most signiicant future impacts from

climate change on their operations will be from potential

fall in oil prices, carbon pricing mechanisms, accessibility

to debt and equity funding and ability to retain employee

and stakeholder conidence in their commitments.

These are explained on pages 38 to 47 in the Task Force

for Climate related Financial Disclosures and on pages

52 to 56 in the principal risks and uncertainties. They

have also explained their climate commitments on

page 33. All of these disclosures form part of the “Other

information”, rather than the audited inancial statements.

Our procedures on these unaudited disclosures

therefore consisted solely of considering whether they

are materially inconsistent with the inancial statements,

or our knowledge obtained in the course of the audit or

otherwise appear to be materially misstated, in line with

our responsibilities on “Other information”.

In planning and performing our audit we assessed the

potential impacts of climate change on the Group’s

business and any consequential material impact on its

inancial statements.

The group has explained in note 25 how they have

relected the impact of climate change in their inancial

statements, including how this aligns with their

commitment to being Net Zero by 2030 on Scope 1 and

Scope 2 GHG emissions on a net equity basis supporting

the goal of limiting global temperature rise to well below

2o C as per Article 2 of the Paris Agreement. Signiicant

judgements and estimates relating to climate change are

included in note 25. These disclosures also explain where

governmental and societal responses to climate change

risks are still developing, and where the degree of certainty

of these changes means that they cannot be taken into

account when determining asset and liability valuations

under the requirements of UK adopted international

accounting standards and International Financial

Reporting Standards adopted pursuant to Regulation (EC)

No. 1606/2002 as it applies in the European Union. In note

25 to the inancial statements supplementary sensitivity

disclosures of the impact of changes in oil price under IEA

scenario-Net Zero Emission by 2050 have been provided.

Our audit eort in considering the impact of climate

change on the inancial statements was focused on

evaluating management’s assessment of the impact

of climate risk, physical and transition, their climate

commitments, the eects of material climate risks

disclosed on pages 38 to 47 and the signiicant

judgements and estimates disclosed in note 25 and

whether these have been appropriately relected in oil and

gas asset values where these are impacted by future cash

lows and associated sensitivity disclosures (see note 25),

and in the timing and nature of decommissioning liabilities

recognised, (see note 25), following the requirements

of UK adopted international accounting standards and

International Financial Reporting Standards adopted

pursuant to Regulation (EC) No. 1606/2002 as it applies

in the European Union. As part of this evaluation, we

performed our own risk assessment, supported by

our climate change internal specialists. This included

making inquiries of the Head of Sustainability and Group

Finance teams, and a review of peer disclosures and

sector guidance on climate change and energy transition

to determine the risks of material misstatement in the

inancial statements from climate change which needed to

be considered in our audit.

We also challenged the Directors’ considerations of

climate change risks in their assessment of going

concern and viability and associated disclosures. Where

considerations of climate change were relevant to our

assessment of going concern, these are described above.

Based on our work, whilst we have not identiied the

impact of climate change on the inancial statements to

be a standalone key audit matter, we have considered the

impact on the following key audit matters: Recoverability

of Kenya Intangible Exploration and Evaluation Asset

(‘E&E’) and Recoverability of Property, Plant and Equipment

(‘PP&E’). Details of the impact, our procedures and indings

are included in our explanation of key audit matters below.

#### e udt mtters

Key audit matters are those matters that, in our professional

judgment, were of most signiicance in our audit of the

inancial statements of the current period and include the

most signiicant assessed risks of material misstatement

(whether or not due to fraud) that we identiied. These

matters included those which had the greatest eect on:

the overall audit strategy, the allocation of resources in the

audit; and directing the eorts of the engagement team.

These matters were addressed in the context of our audit

of the inancial statements as a whole, and in our opinion

thereon, and we do not provide a separate opinion on

these matters.

Key observations communicated

#### Recoverblt of en

#### Intnble Explorton nd

#### Evluton Asset (‘E&E’)

This is an estimate based on

uncertain outcomes. The

recoverability of the Kenya E&E asset

of $242.2m carries inherent risks

that the project does not progress to

development, requiring the write-

o or impairment of the related

capitalised costs, when the relevant

IFRS requirements are met.

Refer to the Audit Committee Report

(page 82); Accounting policies (page

142); and Note 8 of the Consolidated

Financial Statements (pages 151-153)

Determining the recoverable value of

the Kenya E&E asset is judgemental

given the uncertainties surrounding

the progression of the project to

Final Investment Decision (‘FID’).

Management has performed an

impairment assessment under the

value-in-use (‘VIU’) methodology

where estimates are made for key

inputs including oil prices; discount

rates; production proiles; cost

proiles and iscal terms.

The VIU recoverable value is risk-

adjusted for uncertainties associated

with the Group’s ability to recover

the value of the asset. These

uncertainties include the ability to

secure a strategic partner through a

farm down, obtaining government

deliverables (for example access to

land and water and improved iscal

terms), and arranging inancing to

develop the asset, which represent a

source of potential management bias.

As a result of these factors, there

is signiicant judgement relating to

the Kenya E&E asset and whether an

impairment or impairment reversal

is required at year end. As disclosed

in Note 8, changes in signiicant

assumptions can result in a material

impairment charge, or impairment

reversal. An impairment of $17.9m has

been recorded in the current year.

Our procedures included, amongst others:

•  conirmed our understanding of Tullow’s

impairment testing process, as well as the control

environment implemented by management by

performing a walkthrough of the process;

•  read the Kenya Joint Operating Agreement and

communication with the Government of Kenya

(GoK) to conirm that the transfer of interest is

unconditional and irrevocable, and eective from

30 June 2023;

•   performed press searches to corroborate

management’s judgement that the other JV

partners have permanently withdrawn;

•  evaluated the professional qualiications and objectivity

of management’s external experts who performed the

detailed preparation of the resources estimates in 2021.

With no material changes to the development plan, we

consider it appropriate for management to continue to

rely on the 2021 report for oil and gas resources

estimates;

•  reconciled the oil and gas resources and cost

estimates used in the impairment model to the

resources report produced by the Management’s

external expert and Field Development Plan (FDP)

submitted to the GoK;

•  engaged our valuation specialists to test the

mathematical accuracy and formulae integrity of

management’s model;

•  evaluated the appropriateness of management’s

discount rate for Kenya based on an independent

re-calculation of the discount rate including an

assessment of country speciic risks;

•  compared Tullow’s commodity price scenarios to

assessments provided by our valuation specialists

and to prices used by peer companies. We also

compared Tullow’s prices to the IEA’s Net Zero

Emissions 2050 (NZE) and to the Announced

Pledges Scenario (APS) price assumptions as

potential contradictory evidence for estimates of

future oil prices;

•  sensitised the valuation based on signiicant

assumptions, such as oil price and discount rate,

and audited sensitivities performed by Tullow,

including using the IEA’s Net Zero Emissions oil

price forecast post-2030;

•  engaged our valuation specialists to evaluate

management’s probabilistic methodology for

relecting uncertainties associated with the project

to derive risk-adjusted recoverable value;

We consider it is reasonable

that Tullow is entitled to 100%

of the economic interest in the

Kenya JV as at 31 December

2023, as the JV partners have

issued withdrawal notices

and public statements which

are considered irrevocable as

per the Kenya Joint Operating

Agreement.

We consider acceptable

the judgements used by

management in calculating

a gross NPV and then

applying probabilities to

relect the remaining project

uncertainties to calculate the

recoverable amount.

On sensitivity disclosures,

management has appropriately

calculated and disclosed the

impact on the value of the

Kenya asset under the IEA’s

NZE scenario.

#### Evluton Asset (‘E&E’)

#### contnued

We consider that the risk associated

with this key audit matter has

increased compared to the previous

year following withdrawal of the other

JV Partners from the Kenya Joint

Venture and transfer of their equity

interest to Tullow. This withdrawal

and transfer of interest is subject to

the Government of Kenya’s consent

which is yet to be received as of the

date of our report. Management has

applied judgement in determining

Tullow has acquired the 50%

additional interest during the year.

•  assessed the appropriateness of the probabilistic

assessment used to adjust for the uncertainties in

computing the recoverable amount of the asset by

independently evaluating each uncertainty’s facts

and circumstances through inspection of

supporting evidence including communications

with a potential farm down partner and the GoK

and discussions with management outside of the

inance function;

•  evaluated management’s impact assessment of

potential physical risks arising from climate change

and carbon intensity of the project and whether this

may impact the chances of development; and

•  assessing whether the disclosures provided in the

inancial statements relect management’s

judgements, risk

s and uncertainties of the project.

The audit procedures were performed by the

group audit team with the assistance of valuation

specialists. Our audit procedures over this risk area

covers 100% of the reported risk amount.

#### Uncertn Tx Tretments

This is an estimate based on

uncertain outcomes. The risk is that

tax provisions are not appropriate

given the nature of the tax matter.

Refer to the Audit Committee Report

(page 82); Accounting policies

(pages 143-144); and Note 6 of the

Consolidated Financial Statements

(pages 149-150)

Uncertain tax treatments involve

judgement as to whether a matter

is a provision or a contingent

liability and there is subjectivity in

determining whether any estimated

provision is appropriate. This requires

signiicant judgement, including

evaluating the outcome of the tax

matter, the timescale for resolution

and the need to negotiate with

various stakeholders. Furthermore,

the outcome of the tax matter

in most instances is outside of

Tullow’s control.

As described in the Accounting

Policies note section (af) of

the accounting policies to the

Consolidated Financial Statements

Tullow has three ongoing arbitrations

with Ghana Revenue Authority

amounting to $707 million. Our

procedures were focused on these

three matters. Outcomes not in

Management’s favour, that are not

provided for appropriately, could

result in material charges through the

Group’s proit and loss once settled.

Our procedures included, amongst others:

•  conirmed our understanding of Tullow’s taxation

process, as well as the control environment

implemented by management by performing a

walkthrough of the process;

•  obtained and read the correspondence with

tax authorities and when required used our

local audit teams and tax specialists to assess

management’s assumptions and judgements

regarding the level of provisions made;

•  inspected external legal and tax opinions,

where considered necessary, to corroborate

management’s assessment of the risk proile in

respect of the tax claims;

•  evaluated the professional qualiications and

objectivity of management’s external experts;

•  discussed the likelihood and quantum of any

potential settlement with management outside

the inance/tax function including the General

Counsel, CEO and Chair;

•  Reviewed publicly available information

regarding other signiicant tax claims against

multi-nationals in Ghana, in particular MTN,

to understand the basis of the claim and

the outcome;

•  obtained direct conirmation from external

legal counsel to corroborate the status and

management position for material litigations;

•  obtained Tullow’s uncertain tax treatment

assessments and audited the associated

workings, including assessing any exposures

and provisions were appropriately extrapolated

for periods which have yet to be assessed by tax

authorities; and

Based on the evidence

obtained and audit

procedures performed,

including inspecting external

legal and tax opinions, we are

satisied that the accounting

treatment and disclosures

in respect of litigations and

uncertain tax treatments is

appropriate.

We also concluded that the

disclosures made in the

inancial statements are

appropriate.

area covers 100% of the reported risk amount.

Recoverblt of Propert,

#### Plnt nd Equpment

(‘PP&E’)

This is a forecast-based estimate.

The risk is that potential impairments

are not identiied on a timely basis.

The risk is similar to 2022 given the

reduction in TEN reserves oset by

an increase in the long-term oil price

assumption of $5/bbl.

Refer to the Audit Committee report

(page 82); Accounting policies

(pages 142-143); and Note 9 of the

Consolidated Financial Statements

(pages 153-155))

Auditing the impairment of PP&E

involves estimation of key inputs

in particular commodity price

assumptions and discount rates.

Changes to any of these key inputs

could lead to a further impairment

or a reversal of impairment, hence

this is considered a key audit

matter. Following the identiication

of indicators of impairment in the

TEN CGU and impairment reversals

for the Group’s remaining CGUs,

the carrying values were tested for

impairment or impairment reversal.

A net impairment of $301.2 million

was recorded.

We consider that the risk associated

with this key audit matter has

remained consistent with the

previous year.

Our procedures included, amongst others:

•  conirmed our understanding of Tullow’s

impairment testing process, as well as the control

environment implemented by management by

performing a walkthrough of the process;

•  engaged our valuation specialists to test the

mathematical accuracy and formulae integrity of

management’s model;

•  compared Tullow’s commodity price scenarios to

assessments provided by our valuation specialists

and to prices used by peer companies. We also

compared Tullow’s prices to the IEA’s Net Zero

Emissions 2050 (NZE) and to the Announced

Pledges Scenario (APS) price assumptions

as potential contradictory evidence for best

estimates of future oil prices;

•  assessed the appropriateness of management’s

impairment discount rates including an

independent re-calculation of the discount rate

including an assessment of country speciic risks;

•  reconciled production and cost proiles used

in the impairment model to the reserves report

produced by management’s external expert;

•  evaluated the professional expertise and

objectivity of management’s external experts;

•  evaluating the consistency of assumptions used

in the impairment model with other areas of the

audit such as going concern;

•  testing whether decarbonisation costs were

incorporated in the models; and

•  evaluated management’s impact assessment

of potential physical risks arising from climate

change and whether this may impact the carrying

value of the asset; and

•  audited sensitivities performed by Tullow

including using the IEA’s Net Zero Emissions oil

price curve and the IEA’s Announced Pledge

Scenario (APS) price curve.

The audit procedures were performed by our group

engagement team with the assistance of valuation

specialists.

We reported to the Audit

Committee that, based on

our testing performed and

the subsequent adjustments

made by management,

we considered the current

period impairment charge is

fairly stated.

We also reported that

management had

appropriately included costs

for decarbonisation projects

identiied within the Ghana

asset impairment models.

On sensitivity disclosures,

management appropriately

disclosed the impact on the

value of PP&E under the IEA’s

NZE scenario.

Tullow Oil plc Annual Report and Accounts 2023 – 127

Financial statements Supplementary informationStrategic report Corporate governance

#### e udt mtters contnued

In the prior year, our auditor’s report included key audit

matters in relation to the Fair valuation of additional interest

acquired in Ghana assets and Impairment of Investment in

subsidiaries. Since the acquisition was completed in 2022,

the fair valuation of additional interest acquired in Ghana

assets has not been considered as a key audit matter in

the current year. Furthermore, Impairment of investment in

subsidiaries was identiied as a key audit matter following

identiication of a prior year error in calculating the

recoverable value of investments. In the current year, this

has not been identiied as a key audit matter as no similar

error was identiied, resulting in a reduction in executive

involvement and lower allocation of resources.

#### Our pplcton of mterlt

We apply the concept of materiality in planning and

performing the audit, in evaluating the eect of identiied

misstatements on the audit and in forming our audit opinion.

Mterlt

The magnitude of an omission or misstatement that,

individually or in the aggregate, could reasonably be

expected to inluence the economic decisions of the users

of the inancial statements. Materiality provides a basis for

determining the nature and extent of our audit procedures.

We determined materiality for the Group to be $29.4 million

(2022: $26.2 million), which is 2.6% (2022: 2.5%) of Adjusted

EBITDAX. Our key criterion in determining materiality remains

our perception of the needs of Tullow’s stakeholders. We

consider which earnings, activity or capital-based measure

aligns best with the expectations of the users of Tullow’s

inancial statements. In doing so, we apply a ‘reasonable

investor perspective’, which relects our understanding of

the common inancial information needs of the members of

Tullow as a group. We believe that Adjusted EBITDAX provides

us with the most appropriate measure upon which to calculate

materiality as it represents a key performance indicator used

by Tullow’s investors.

We have excluded non-recurring items such as impairments

of E&E assets and producing oil & gas assets, non-cash

movements in provisions and gain on bond buyback to

ensure we are using a consistent measure representative of

the underlying business. The non-recurring items excluded in

2023 were impairment of E&E assets ($27 million), impairment

of oil and gas assets ($401 million) oset by non-cash

movement in provisions ($22 million) and gain on bond

buyback ($86 million).

For 2023, we have not used a normalised measure based

on our observations of the current year oil prices and

analysis of forecast price curves and noted that oil price

volatility caused by the pandemic and the outbreak of

war in Ukraine 2023 has reduced. Consequently, we have

ceased normalising Adjusted EBITDAX in the current year.

We determined materiality for the Parent Company

to be $36.0 million (2022: $28.2 million), which is 1.4%

(2022:1.4%) of Net Assets. The basis for calculating Parent

Company materiality has not changed since the prior year.

During the course of our audit, we reassessed initial

materiality and concluded that the Group’s actual

performance in 2023 did not aect our initial materiality.

As such, our materiality was unchanged from planning.

Performnce mterlt

The application of materiality at the individual account

or balance level. It is set at an amount to reduce to an

appropriately low level the probability that the aggregate

of uncorrected and undetected misstatements exceeds

materiality.

On the basis of our risk assessments, together with our

assessment of the Group’s overall control environment,

our judgement was that performance materiality was 50%

(2023: 50%) of our planning materiality, namely $14.7m

(2022: $13.1m). We have set performance materiality at

this percentage due to our assessment of the nature,

number and impact of the adjusted and unadjusted audit

dierences identiied in 2022 audit.

Audit work at component locations for the purpose

of obtaining audit coverage over signiicant inancial

statement accounts is undertaken based on a percentage

of total performance materiality. The performance

materiality set for each component is based on the relative

scale and risk of the component to the Group as a whole

and our assessment of the risk of misstatement at that

component. In the current year, the range of performance

materiality allocated to components was $3.7m to $14.7m

(2022: $2.6m to $13.1m).

#### Reportn threshold

An amount below which identiied misstatements are

considered as being clearly trivial.

We agreed with the Audit Committee that we would

report to them all uncorrected audit dierences in excess

of $1.5m (2022: $1.2m), which is set at 5% of planning

materiality, as well as dierences below that threshold that,

in our view, warranted reporting on qualitative grounds.

We evaluate any uncorrected misstatements against both

the quantitative measures of materiality discussed above

and in light of other relevant qualitative considerations in

forming our opinion.

The other information comprises the information included

in the annual report set out on pages 1 to 118 and 189 to

#### Corporte Governnce Sttement

We have reviewed the directors’ statement in relation to

going concern, longer-term viability and that part of the

Corporate Governance Statement relating to the group

and company’s compliance with the provisions of the UK

Corporate Governance Code speciied for our review by

the Listing Rules.

Based on the work undertaken as part of our audit, we

have concluded that each of the following elements of the

Corporate Governance Statement is materially consistent

with the inancial statements or our knowledge obtained

during the audit:

•  Directors’ statement with regards to the appropriateness

of adopting the going concern basis of accounting

and any material uncertainties identiied set out on

pages 63 to 64;

•  Directors’ explanation as to its assessment of the

company’s prospects, the period this assessment

covers and why the period is appropriate set out on

pages 57 to 58;

•  Director’s statement on whether it has a reasonable

expectation that the group will be able to continue in

operation and meets its liabilities set out on page 57;

•  Directors’ statement on fair, balanced and

understandable set out on page 118;

•  Board’s conirmation that it has carried out a robust

assessment of the emerging and principal risks set out

on page 86;

•  The section of the annual report that describes the

review of eectiveness of risk management and internal

control systems set out on pages 85 and 86; and;

•  The section describing the work of the audit committee

set out on page 82

#### Responsbltes of drectors

As explained more fully in the directors’ responsibilities

statement set out on page 118, the directors are

responsible for the preparation of the inancial statements

and for being satisied that they give a true and fair view,

and for such internal control as the directors determine

is necessary to enable the preparation of inancial

statements that are free from material misstatement,

whether due to fraud or error.

In preparing the inancial statements, the directors are

responsible for assessing the group and parent company’s

ability to continue as a going concern, disclosing, as

applicable, matters related to going concern and using the

going concern basis of accounting unless the directors

either intend to liquidate the group or the parent company

or to cease operations, or have no realistic alternative

but to do so.

Audtor’s responsbltes for the udt of

#### the fnncl sttements

Our objectives are to obtain reasonable assurance about

whether the inancial statements as a whole are free from

material misstatement, whether due to fraud or error,

and to issue an auditor’s report that includes our opinion.

Reasonable assurance is a high level of assurance, but is

not a guarantee that an audit conducted in accordance

with ISAs (UK) will always detect a material misstatement

when it exists. Misstatements can arise from fraud or

error and are considered material if, individually or in

the aggregate, they could reasonably be expected to

inluence the economic decisions of users taken on the

basis of these inancial statements.

Explnton s to wht extent the udt ws

consdered cpble of detectn rreulrtes,

ncludn frud

Irregularities, including fraud, are instances of non-

compliance with laws and regulations. We design

procedures in line with our responsibilities, outlined

above, to detect irregularities, including fraud. The risk

of not detecting a material misstatement due to fraud is

higher than the risk of not detecting one resulting from

error, as fraud may involve deliberate concealment by,

for example, forgery or intentional misrepresentations, or

through collusion. The extent to which our procedures

are capable of detecting irregularities, including fraud is

detailed below.

However, the primary responsibility for the prevention

and detection of fraud rests with both those charged with

governance of the company and management.

•  We obtained an understanding of the legal and

regulatory frameworks that are applicable to the group

and determined that the most signiicant are those

that related to the reporting framework (UK-adopted

IAS, IFRS, Companies Act 2006, the UK Corporate

Governance Code and Listing Rules of the UK Listing

Authority) and the relevant tax compliance regulations

in the jurisdictions in which Tullow operates. In addition,

we concluded that there are certain signiicant

laws and regulations that may have an eect on the

determination of the amounts and disclosures in the

inancial statements, relating to health and safety,

employee matters, environmental matters and bribery

and corruption practices.

•  We understood how Tullow Oil plc is complying with

those frameworks by making inquiries of management,

internal audit and those responsible for legal and

compliance procedures. We corroborated our enquiries

through review of board minutes, papers provided to

Audit committees and correspondence received from

regulatory bodies.

•  We assessed the susceptibility of the group’s inancial

statements to material misstatement, including how

fraud might occur by considering the degree of

incentive, opportunity and rationalisation that may

exist within the group. We did this by meeting with

management to gain an understanding of where

there was susceptibility to fraud, how the company is

complying with international tax laws and regulations,

procedures in place to address the risk of bribery and

corruption in high-risk countries. We also performed

procedures around setting key performance indicators

and, alongside our forensics specialists, assessed

whistleblowing incidences for those with a potential

inancial reporting impact.

•  Based on this understanding we designed our audit

procedures to identify non-compliance with such laws

and regulations. Our procedures involved journal entry

testing, with a focus on journals meeting deined risk

criteria based on our understanding of the business;

inquiries with legal counsel, group management, internal

audit and all full and speciic scope management; review

of volume and nature of whistleblowing complaints

received during the year; review of legal expense

accounts; and performance of adverse press searches.

•  Based on the results of our audit procedures, and where

instances of potential non-compliance were identiied,

we consulted the relevant EY local teams andEY

specialists who aided us in determining suicient,

andexecuting appropriate, procedures to respond

totheriskidentiied.

A further description of our responsibilities for

the audit of the inancial statements is located

on the Financial Reporting Council’s website at

https://www.frc.org.uk/auditorsresponsibilities.

Thisdescription forms part of our auditor’s report.

#### Other mtters we re requred to ddress

•  Following the recommendation from the audit

committee we were appointed by the company on 21

July 2020 to audit the inancial statements for the year

ending 31 December 2020 and subsequent inancial

periods. The period of total uninterrupted engagement

including previous renewals and reappointments is 4

years, covering the years ending 2020 to 2023.

•  The audit opinion is consistent with the additional report

to the audit committee.

#### Use of our report

This report is made solely to the company’s members,

as a body, in accordance with Chapter 3 of Part 16 of

the Companies Act 2006. Our audit work has been

undertaken so that we might state to the company’s

members those matters we are required to state to them in

an auditor’s report and for no other purpose. To the fullest

extent permitted by law, we do not accept or assume

responsibility to anyone other than the company and the

company’s members as a body, for our audit work, for this

report, or for the opinions we have formed.

assumptions for the going concern assessment:

•  Base Case: $78/bbl for 2024, $75/bbl for 2024; and

•  Low Case: $70/bbl for 2024, $70/bbl for 2025.

The Low Case includes, amongst other downside

assumptions, a 10% production decrease and 10%

increased operating costs compared to the Base Case.

Management has also considered additional outlflows in

respect of all ongoing litigations/arbitrations within the

Low Case, with an additional $48 million outlow bflow being

included for the cases expected to progress in the period

under assessment. The low case does not include the

outlow for the full expoflow for the full exposure on Ghana BPRT arbitration of

$320 million (refer to Note 1(af) Ghana tax assessments for

details). The remaining arbitration cases are not expected

to conclude within the going concern period and no

outlows have beflows have been included in that respect.

At 31 December 2023, the Group had $1.0 billion liquidity

The amounts involved may be material. The Group has

repaid $0.3 billion and $0.2 billion of the 2025 and 2026

(e) Bss of consoldasis of consolidatontion

The consolidated Financial Statements incorporate

the Financial Statements of the Company and entities

controlled by the Company (its subsidiaries) made up

to 31 December each year. Control is achieved where

the Company has the power over an investee entity,

is exposed, or has rights, to variable returns from its

involvement with the investee and has the ability to use its

power to aect its returns. power to affect its returns.

The results of subsidiaries acquired or disposed of during

the year are included in the Group income statement

from the transaction date of acquisition, being the date

on which the Group gains control, and will continue to be

included until the date that control ceases.

If the Group loses control over a subsidiary, it derecognises

the related assets, liabilities, non-controlling interest and

other components of equity, while any resultant gain or loss

is recognised in proit or lod in profit or loss. Any investment retained is

recognised at fair value. All intra-Group transactions, balances,

income and expenses are eliminated onconre eliminated on consolidation.

Where necessary, adjustments are made to the Financial

Jont rrnementsJoint arrangements

The Group is engaged in oil and gas exploration,

development and production through unincorporated joint

arrangements; these are classiisified as joint operations in

accordance with IFRS 11. The Group accounts for its share of

the results and assets and liabilities of these joint operations.

In addition, where Tullow acts as operator to the joint

operation, the gross liabilities and receivables (including

amounts due to or from non-operating partners) of the joint

operation are included in the Group’s balance sheet.

(f) Busness c(f) Business combntonsombinations

The acquisition method of accounting is used to account

for all business combinations, regardless of whether

equity instruments or other assets are acquired. The

consideration transferred for the acquisition comprises:

•  Fair values of the assets transferred.

•  Liabilities incurred to the former owners of the

acquired business.

•  Equity interests issued by the Group.

•  Fair value of any asset or liability resulting from a

contingent consideration arrangement.

•  Fair value of any pre-existing equity interest in

thesubsidiarthe subsidiary.

The Group determines that it has acquired a business

when the acquired set of activities and assets include an

input and a substantive process that together signiicgnificantly

contribute to the ability to create outputs. The acquired

process is considered substantive if it is critical to the

ability to continue producing outputs, and the inputs

acquired include an organised workforce with the

necessary skills, knowledge, or experience to perform

that process or it signiiignificantly contributes to the ability

to continue producing outputs and is considered unique

or scarce or cannot be replaced without signit significant cost,

eorteffort, or delay in the ability to continue producing outputs.

Identiiablntifiable assets acquired and liabilities and contingent

liabilities assumed when control is obtained over a business,

and when an interest or an additional interest is acquired in a

joint operation which is a business are, with limited exceptions,

measured initially at their fair values at the acquisition date.

Acquisition-related costs are expensed as incurred.

The excess of the consideration transferred, amount of

any non-controlling interest in the acquired entity, and

acquisition-date fair value of any previous equity interest in

the acquired entity over the fair value of the net identiiablntifiable

assets acquired is recorded as goodwill. If those amounts

are less than the fair value of the net identiiaentifiable assets of

the business acquired, the dierencquired, the difference is recognised directly

in proit or loin profit or loss as a bargain purchase.

or services are transferred to the customer at an amount

that relects the cthat reflects the consideration towhich the Go which the Group expects

to be entitled in exchange for those goods or services.

The Group has concluded that it isthed that it is the principal inall of ipal in all of

its revenue arrangements since it controls the goods or

services before transferring them to the customer.

) Revenue fri) Revenue from crude oude oil sll sales

The crude oil produced by the upstream operations is

sold to external customers. Revenue from the sale of

crude oil is recognised atthe pd at the point in time when control

of the product is transferred to the customer, which is

typically when goods are delivered, and title has passed.

The transportation and shipping costs associated with the

transfer of the product to the point of sale is recognised as

a selling cost.

Under the terms of the relevant production sharing

arrangements, the Group is entitled to its participating

share in the crude oil based on the Group’s working

interest. Revenue from contracts with customers

is recognised based on the actual volumes sold to

customers. No adjustments are made to revenue for

any dierences bany differences between volumes sold to customers

and unsold volumes which the Group is entitled to sell

based on its working interest. Revenue in respect of such

volumes is only recognised when there is a transfer of

output to the Group’s customers. Dierenc. Differences between

the volume which the Group is entitled to sell based on its

working interest and the actual volumes that the Group

has sold to customers are recognised as an over/underlift

(note (h)) within cost of sales.

Under the terms of the Production Sharing Contracts in

Gabon and Côte d’Ivoire, the Group is not required to pay

any corporate income taxes. The share of the proit oil fit oil

which the government is entitled to is deemed to include

a portion representing the notional corporate income tax

paid by the government on behalf of the contractors. This

portion of notional corporate income tax is presented

as an income tax expense with a corresponding amount

recognised in Revenue.

The Group’s sales of crude oil are priced based on the

consideration specicified in contracts with customers with

reference to quoted market prices in active markets,

adjusted for a quality dierential bay differential based on gravity of the

crude oil sold relative to Brent. Invoices are typically paid

on 30-60 day terms.

For certain non–operated arrangements, the Group’s stake is

structured as a carried interest, in which all costs relating to

the performance of petroleum operations are borne by the

operator and other Joint Venture Partners and are recovered

(h) Over/underlferlift

Lifting or oting or offtake arrangements for oil and gas produced

in certain of the Group’s jointly owned operations are

such that 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 is underlift or overlift.

Underlift and overlift are valued at market value and

included within receivables and payables respectively.

on a weighted average cost basis and comprises direct

purchase costs. Net realisable value is determined by

reference to prices existing at the balance sheet date, less

estimated costs of completion and the estimated costs

necessary to make the sale.

subsequent write-down of the asset or disposal group to

a revised fair value less costs to sell is recognised at each

reporting date. Non-current assets and disposal groups

are classiieified as held for sale if their

carrying amount will be recovered through a sale

transaction rather than through continuing use. This

condition is regarded as met only when the sale is highly

probable and the asset (or disposal group) is available for

immediate sale in its present condition. Management must

be committed to the sale, which should be expected to

qualify for recognition as a completed sale within one year

The Group adopts the successful eorsful efforts method of

accounting for exploration and evaluation costs. Pre-

licence costs are expensed in the period in which they

are incurred. All licence acquisition, exploration and

evaluation costs and directly attributable administration

costs are initially capitalised in cost centres by well, ield oentres by well, field or

exploration area, as appropriate.

These costs are then written o asts are then written off as exploration costs in the

income statement unless commercial reserves have been

established or the determination process has not been

completed and there are no indications of impairment.

Exploration and evaluation assets are tested for impairment

when reclassiied teclassified to development assets, or whenever facts

and circumstances indicate impairment. An impairment

loss is recognised for the amounts by which the exploration

and evaluation assets’ carrying amount exceeds their

recoverable amount. The recoverable amount is the higher

of the exploration and evaluation asset’s fair value less cost

to sell and their value in use.

All ieAll field development costs are capitalised as property, plant

and equipment. Property, plant and equipment related to

production activities is amortised in accordance with the

Group’s depletion and amortisation accounting policy.

Cash consideration received on farm-down of exploration

and evaluation assets is credited against the carrying value

of the asset. The excess amount over the carrying value of

the asset is recognised as a gain on disposal of exploration

and evaluation assets in the statement of proit or loe statement of profit or loss.

(m) Commercl reserial reserves

Commercial reserves are proven and probable oil

and gas reserves, which are deinch are defined as the estimated

quantities of crude oil, natural gas and natural gas liquids

which geological, geophysical and engineering data

demonstrate with a speciiefied degree of certainty to

berecoverable in fube recoverable in future years from known reservoirs and

which are considered commercially producible. There

should be a 50% statistical probability that the actual

quantity of recoverable reserves will be more than the

amount estimated as proven and probable reserves and a

50% statistical probability that it will be less.

(n) Depleton nn) Depletion and mord amortstistonation

All expenditure carried within each iach field is amortised from

the commencement of production on a unit of production

basis, which is the ratio of oil and gas production in the

period to the estimated quantities of commercial reserves

at the end of the period plus the production in the

period, generally on a ielrally on a field-by-ield baby-field basis or by a group of

ielfields which are reliant on common infrastructure. Costs

used in the unit of production calculation comprise the

net book value of capitalised costs plus the estimated

future ield develofuture field development costs required to recover the

commercial reserves remaining. Changes in the estimates

of commercial reserves or future ield dr future field development costs

are dealt with prospectively.

(o) Impo) Imparment of properirment of propertty, plnt, plant

The Group assesses at each reporting date whether there

is an indication that an asset or Cash Generating Unit (CGU)

may be impaired. In assessing whether an impairment

is required, the carrying value of the asset or CGU is

compared with its recoverable amount. The recoverable

amount is the higher of the asset’s/CGU’s fair value less

costs of disposal (FVLCD) and value in use (VIU). Given the

nature of the Group’s activities, information on the fair value

of an asset is usually diually difficult to obtain unless negotiations

with potential purchasers or similar transactions are

taking place.

described below is VIU. The Group estimates VIU using a

discounted cash loted cash flow model.

In order to discount the future cash unt the future cash flows the Group

calculates asset or CGU-specicific discount rates.

The discount rates are based on an assessment of a relevant

peer group’s post-tax weighted average cost of capital

(WACC). Thepohe post-tax WACC is subsequently grossed up to

a pre-tax rate. The Group then deducts any exploration risk

premium which is implicit within a peer group’s WACC and

subsequently applies additional country risk premium for all

CGUs, an element of which isdetermines determined by whether the

assets are onshore oroshor offshore.

Where there is evidence of economic interdependency

in accordance with local conditions and requirements.

Changes in the estimated timing of decommissioning

or an unrecognised ed firmcomirm commitment.

•  Cash low heh flow hedges when hedging the exposure to

•  Hedges of a net investment in a foreign operation.

At the inception of a hedge relationship, the Group

formally designates and documents the hedge relationship

to which it wishes toapply hes to apply hedge accounting.

The documentation includes identiicatification of the hedging

instrument, the hedged item, the nature of the risk being

hedged and how the Group will assess whether the

hedging relationship meets the hedge eeche hedge effectiveness

requirements (including the analysis of sources of hedge

ineectiveneineffectiveness and how the hedge ratio is determined).

A hedging relationship qualiielifies for hedge accounting if it

meets all of the following eectivenes all of the following effectiveness requirements:

•  There is ‘an economic relationship’ between the hedged

item and the hedging instrument.

•  The eect of cThe effect of credit risk does not ‘dominate the value

changes’ that result from that economic relationship.

•  The hedge ratio of the hedging relationship is the same

as that resulting from the quantity of the hedged item

that the Group actually hedges and the quantity of the

hedging instrument that the Group actually uses to

hedge that quantity of hedged item.

If a hedging relationship ceases to meet the hedge

eectiveneeffectiveness requirement relating to the hedge ratio

but the risk management objective for that designated

hedging relationship remains the same, the Group adjusts

the hedge ratio of the hedging relationship (i.e.rebalancship (i.e. rebalances

The Group designates only the intrinsic value of option

contracts as a hedged item, i.e. excluding the time value of

value of the option are recognised in other comprehensive

The Group uses oil option contracts for its exposure to

shorter of the asset’s useful life and the lease term on

a straight-line basis, or applying the unit of production

method, and the Joint Venture receivable is allocated

against the monthly Joint Venture billing cycle.

The initial measurement of the corresponding lease liability

cost using the eective inte effective interest method. It is remeasured

when there is a change in future lease payments arising

from a change in an index or rate, if there is a change in the

Group’s estimate of the amount expected to be payable

under a residual value guarantee or if the Group changes

its assessment of whether it will exercise a purchase,

extension or termination option. When the lease liability

is remeasured in this way, a corresponding adjustment is

made to the carrying amount of the right-of-use asset or

is recorded in proit or losrofit or loss if the carrying amount of the

right-of-use asset has been reduced to zero.

The Group has elected not to recognise right-of-use assets

and lease liabilities for short-term leases that have a lease

term of 12months or leterm of 12 months or less, and leases of low-value assets

with a value of $5,000.

Over the course of a lease contract, there will be taxable

timing dierenctiming differences that could give rise to deferred tax,

subject to local tax lawsand regulationx laws and regulations.

Extension and termination options are included in a

number of property and equipment leases across the

Group. These are used tomaximise are used to maximise operational lerational flexibility

in terms of managing the assets used in the Group’s

operations. The majority of extension and termination

options held are exercisable only by the Group and not by

the respective lessor.

(x) Shrhare-bsed pbased pamentsyments

The Group has applied the requirements of IFRS 2 Share-

based Payments. The Group has share-based awards that

are equity settled and cash settled as deinefined by IFRS

2. The fair value of the equity settled awards has been

determined at the date of grant of the award allowing for

the eect of any marketthe effect of any market-based performance conditions.

#### (x) Shre-bsed pments contnued

This fair value, adjusted by the Group’s estimate of the

number of awards that will eventually vest as a result of

non-market conditions, is expensed uniformly over the

vesting period.

The fair values were calculated using a binomial option

pricing model with suitable modiodifications to allow for

employee turnover after vesting and early exercise. Where

necessary, this model is supplemented with a Monte Carlo

model. The inputs to the models include: the share price at

date of grant; exercise price; expected volatility; expected

dividends; risk-free rate of interest; and patterns of exercise

of the plan participants.

For cash settled awards, a liability is recognised for the

goods or service acquired, measured initially at the fair

value of the liability. Ateac. At each balance sheet date until the

liability is settled, and at the date of settlement, the fair

value of the liability is remeasured, with any changes in fair

value recognised in the income statement.

() Fnncl ssets(y) Financial assets

At initial recognition, the Group measures a iasures a financial

asset at its fair value plus, in the case of a inse of a financial asset

not at fair value through proit or losnot at fair value through profit or loss (FVPL), transaction

costs that are directly attributable to the acquisition of the

inanfinancial asset. Transaction costs of inosts of financial assets carried

at FVPL are expensed in proit or lod in profit or loss.

The subsequent measurement of surement of financial assets depends

on their classisification, as set out overleaf.

) Fnncl ssetsi) Financial assets mesured t mortsed cost easured at amortised cost

Assets are subsequently classiisified and measured at

amortised cost when the business model of the Company

is to collect contractual cash lsh flows and the contractual

terms give rise to cash lterms give rise to cash flows that are solely payments

of principal and interest. These assets are carried at

amortised cost using the eeing the effective interest method if

the time value of money is signiicnificant. Gains and losses

are recognised in proit or ld in profit or loss when the assets are

derecognised, modiodified or impaired. This category of

inancifinancial assets includes trade and other receivables.

Financial assets measured at amortised cost include trade

receivables, loans and other receivables that have ixed or s that have fixed or

determinable payments that are not quoted in an active

market. Loans and receivables are measured at amortised

cost using the eective inte effective interest method, less any

impairment. Interest income is recognised by applying the

eective inteffective interest rate, except for short-term receivables

when the recognition of interest would be immaterial.

Interest income is accrued on a time basis, by reference

to the principal outstanding and at the eective intffective interest

rate applicable, which is the rate that exactly discounts

estimated future cash receipts through the expected life of

the inathe financial asset to that asset’s net carrying amount.

Regular way purchases and sales of inas of financial assets are

recognised on trade date, being the date on which the

Group commits to purchase or sell the asset. Financial

assets are derecognised when the rights to receive cash

lows from the inaflows from the financial assets have expired or have been

transferred and the Group has transferred substantially all

the risks and rewards of ownership.

Imprment of trde nd Jont VImpairment of trade and Joint Venture recevblesenture receivables

The Group applies the IFRS 9 simpliimplified approach to

measuring expected credit losses which uses a lifetime

expected loss allowance for all trade receivables. To

measure the expected credit losses, trade receivables

have been grouped based on shared credit risk

characteristics and days past due.

The expected loss rates are based on the payment proileayment profiles

of sales over the historical period and the corresponding

historical credit losses experienced during this period.

These rates are then applied to the gross carrying amount

of the receivable to arrive at the loss allowance for the

period. Based on management assessment, the credit

loss in trade receivables and Joint Venture receivable as at

31D31 December 2023 would be immaterial; therefore, in line

with IFRS 9, no impairment was recognised (2022: $nil).

In order to minimise the risk of default, credit risk is

managed on a Group basis (note 17).

The eective interest method iThe effective interest method is a method of calculating

the amortised cost of a iost of a financial asset and of allocating

(eae) Crtcl cco) Critical accountn udements unting judgements

The Group assesses critical accounting judgements

annually. The following are the critical judgements, apart

from those involving estimations which are dealt with in

policy (af), that the Directors have made in the process of

applying the Group’s accounting policies and that have the

most signiiignificant eect ocant effect on the amounts recognised in the

Financial Statements.

CrrCarrn vlue of ntnble explortonying value of intangible exploration nd  and

evluevaluaton ssets (notetion assets (note 9)

The amounts for intangible exploration and evaluation

assets represent active exploration projects. These

amounts will be written oto tten off to the income statement

as exploration costs unless commercial reserves are

established or the determination process is not completed

and there are no indications of impairment in accordance

with the Group’s accounting policy. The process of

determining whether there is an indicator for impairment

or calculating the impairment requires critical judgement.

The key areas in which management has applied

judgement and estimation are as follows: the Group’s

intention to proceed with a future work programme for a

prospect or licence; the likelihood of licence renewal or

extension; the assessment of whether sur sufficient data exist

to indicate that, although a development in the speciic ific

area is likely to proceed, the carrying amount of the

exploration and evaluation asset is unlikely to be recovered

in full from successful development or by sale; and the

success of a well result or geological or geophysical

survey. Details on impact of these key estimates using

sensitivities applied to impairment models can be found

in note 8.

The most material area where judgement was applied

during 2023 was in the assessment of the value in use

(VIU) of the Kenyan CGU and assessing the likelihood of

recovery of the net book value of the asset. Triggers for

an impairment assessment were identiientified following the

withdrawal of the JV partners and an increase in Group’s

long-term oil price assumption, resulting in an increase in

the underlying value of the project. Due to the stage of this

project being pre-inal investme-final investment decision (FID) and only

having 2C resources booked, the VIU assessment required

estimation and judgement in a number of dierent aspefferent aspects

including oil prices dierentials, uncs differentials, uncontracted cost proiles rofiles

and certain itain fiscal terms. Furthermore, the Group has

identiidentified the following estimation uncertainties, which

require judgement, in respect to the Group’s ability to

realise the estimated VIU; receiving an acceptable oer ffer

from a strategic partner, obtaining ibtaining financing for the

project and government deliverables in form of provision

of required infrastructure and ind fiscal terms. These items

require satisfactory resolution before the Group can

take FID. Due to the binary nature of these uncertainties

the Group was unable to either adjust the cash ash flows

or discount rate appropriately. It has therefore used its

judgement and assessed the probability of achieving FID

and therefore the recognition of commercial reserves.

This probability was applied to the VIU to determine a risk

adjusted VIU and compared against the net book value

of the asset. Basedon this an imd on this an impairment charge of $17.9

million was booked as at 31 December 2023. Should

the uncertainties around the project beresolved the resolved there

will be a reversal of previously recognised impairment.

However, if the uncertainties are not resolved there will

beanabe an additional impairment of $242.2 million.

The key assumptions concerning the future, and other key

sources of estimation uncertainty at the balance sheet

date, that have a signiicignificant risk of causing a material

adjustment to the carrying amounts of assets and liabilities

within the next within the next financial year, are discussed below.

CrrCarrn vlue of properying value of propertty, plnt nd equpment , plant and equipment

Management performs impairment reviews on the Group’s

property, plant and equipment assets at least annually with

reference to indicators in IAS 36 Impairment of Assets.

Where indicators of impairments or impairment reversals

are present and an impairment orimpnt or impairment reversal

test is required, the calculation of the recoverable amount

impairment models.

Key assumptions and estimates in the impairment models

relate to: commodity prices assumptions, pre-tax discount

reserves are determined using estimates of oil and gas in

place, recovery factors and future commodity prices, the

latter having an impact on the total amount of remaining

recoverable reserves and the proportion of the gross

reserves which are attributable to host governments

under the terms of the Production Sharing Contracts.

Future development costs are estimated taking into

account the level of development required to produce the

reserves by reference to operators, where applicable, and

internalenernal engineers.

Net entitlement reserves estimates are subsequently

calculated using the current oil price and cost recovery

assumptions, in line with the relevant agreements.

Changes in reserves as a result of factors such as

production cost, recovery rates, grade of reserves or oil

and gas prices could impact the depletion rates, carrying

Discount rate

The Group has assessed the appropriate incremental

borrowing rate applicable for each contract. Management

has applied the practical expedient which allows for the

adoption of a portfolio approach, where a single discount

rate for a portfolio of leases with similar characteristics

can be applied. As the Group has external borrowings with

a consortium of lenders, these are considered thebered the best

reference for the incremental borrowing rate for the Group

at the lease commencement date if the interest rate

implicit in the lease is not readily determinable. For the

material remeasurements during the year, predominantly

on the TEN FPSO lease discussed in note 18 the Group has

assessed the incremental borrowing rate to be 16.88%.

Determination of the lease term

Lease terms are negotiated on an individual basis and

contain a wide range of dierent terms and cde range of different terms and conditions.

Extension and termination options are included in a

number of property and equipment leases across the

Group. These are used to maximise operational lerational flexibility

in terms of managing the assets used in the Group’s

operations. For leases relating to Joint Venture operations

where there is an option to extend, the Group will only

proceed after it has received Joint Venture approval to

extend. At the inception of new leases in relation to joint

arrangements they do not include any period covered

by an extension option in the lease term because they

cannot be reasonably certain that approval from the other

venturers can be obtained. The majority of extension and

termination options held are exercisable only by the Group

and not by the respective lessor.

In respect of the TEN FPSO lease, the lease term was

updated to relect the mupdated to reflect the management’s best estimate view

that the FPSO will continue to be leased until the cessation

of production in 2032 and assumes an exercise of the

extension option following a decision not to exercise the

purchase option.

Uncertn tUncertain tax tretmentsx treatments

The Group is subject to various material claims which

arise in the ordinary course of its business in various

jurisdictions, including cost recovery claims, claims

from regulatory bodies and both corporate income tax

and indirect tax claims. The Group is in formal dispute

proceedings regarding a number of these tax claims. The

resolution of tax positions, through negotiation with the

relevant tax authorities or litigation, can take several years

to complete. In assessing whether these claims should

be provided for in the Financial Statements, management

has considered them in the context of the applicable

laws and relevant contracts for the countries concerned.

Management has applied judgement in assessing the likely

outcome of the claims and has estimated the instimated the financial

impact based on external tax and legal advice and prior

experience of such claims.

Provisions of $85.0 million (2022: $106.4 million) are included

in income tax payable ($78.3 million (2022:$70.6 million2: $70.6 million)),

deferred tax liability ($nil (2022: $nil)), and provisions ($6.7

million (2022: $35.8 million)). Where these matters relate to

expenditure which is capitalised within Intangible Exploration

and Evaluation Assets and Property, Plant and Equipment, any

dierence bdifference between the amounts accrued and the amounts

settled is capitalised within the relevant asset balance,

subject to applicable impairment indicators. Where these

matters relate to producing activities or historical issues, any

dierencedifferences between the accrued and settled amounts are

taken to theGroup ince Group income statement.

Due to the uncertainty of such tax items, it is possible that on

conclusion of an open tax matter at a future datetx matter at a future date the outcome

may dier signimay differ significantly from management’s estimate. If the

Group was unsuccessful indefendinsful in defending itself from all of these

All sales are made to external customers. Included in revenue arising from Ghana and Non-Operated segments are

revenues of approximately $462.3 million, $326.9 million and $181.9 million relating to the Group’s customers who each

contribute more than 10% of total sales revenue (2022: $696.9 million, $566.1 million, $310.9 million and $242.3 million).

As the sales of oil and gas are made on global markets and are highly liquid, the Group does not place reliance on the

largest customers mentioned above. Payment terms are typically 30 days from the bill of lading.

During 2023, Tullow has entered into an oil marketing contract under which it will sell its crude oil entitlements to

Glencore Energy UK Limited. The contract expires in 2028.

The Group’s proit before taxation will continue to arise in juris profit before taxation will continue to arise in jurisdictions where the eective rre the effective rate of taxation diers from ate of taxation differs from

that in the UK, such as Ghana (35%) and Gabon convention in convention fields (50%), Gabon PSC ieC fields (35%) and CDI PSC (25%).

Furthermore, there is no tax beneit aefit arising on net interest and hedging expense in the UK. Accordingly, the Group’s tax

charge will continue to vary according to the jurisdictions in which pre-tax proits arisre-tax profits arise.

The Group has tax losses of $4,195.3 million (2022: $4,237.4 million) of which $3,109.9 million are available for oset e for offset

indeinitely and $finitely and $1,085.4 million in the next 5-7 years against future taxable proits in the coture taxable profits in the companies in which the losses

arose. Deferred tax assets have not been recognised in respect of losses of $4,165.7 million (2022: $4,128.9 million) as it is

not sunot sufficiently probable that there will be future taxable proits agre will be future taxable profits against which these losses can be utilised.

The Group has recognised deferred tax assets of $7.4 million (2022: $35.8 million) in relation to tax losses only to the

extent of anticipated future taxable income or gains in relevant jurisdictions. The Group has suered thes suffered these losses in

either the current or preceding period in the tax jurisdiction to which the deferred tax asset relates. The tax losses can be

carried forward indeind indefinitely.

There are no temporary dierencey differences relating to unremitted earnings of overseas subsidiaries as the Group is able to

control the timing of the reversal of these temporary dierency differences and it is probable that they will not reverse in the

foreseeable future.

During 2023 nil tax expense (2022: nil tax expense) has been recognised through other comprehensive income.

Globl mnmum top-up txGlobal minimum top-up tax

The Group operates in the UK, which has enacted new legislation to implement the global minimum top-up tax. However,

since the newly enacted tax legislation is only eective frffective from 1 January 2024, there is no current tax impact for the year

ended 31 December 2023. The Group is not expecting to pay top-up taxes in the future because all jurisdictions in

which the Group operates are above 15% and management is not currently aware of any circumstances under which this

might change.

The Group has applied a temporary mandatory relief from deferred tax accounting for the impacts of the top-up tax and

accounts for it as a current tax when it is incurred.

Discussions with the Government of Kenya (GoK) on securing government deliverables and approval of the Field

Development Plan (FDP) have been ongoing since its submission on 10 December 2021. An updated FDP was submitted

on 3 March 2023 and is being reviewed by the GoK before ratiicatiotification by the Kenyan Parliament. Energy and Petroleum

Regulatory Authority (EPRA), the regulator, has engaged third party consultants to review the revised FDP and the current

review period ends on 30 June 2024. The Group expects a production licence to be granted once government due

process has been completed.

On 22 May 2023, Africa Oil Corporation (AOC) and Total Energies (TE) gave notice of their respective withdrawal from the

Blocks 10BA, 10BB and 13T Production Sharing Contracts (PSCs) and the Joint Operating Agreements (JOAs), eective ), effective

30 June 2023, quoting diering internal stratffering internal strategic objectives as reasons. The withdrawal is ultimately subject to the GoK’s

consent, at which stage the transaction will be considered completed and Tullow will have full rights and liabilities under

the JOA. Pending GoK approval, per the terms of the agreement, the participating interest (PI) vests in trust for the sole

and exclusive benenefit of Tullow, who is the only remaining Joint Venture Partner.

In management’s view, in light of public statements and announcements made by AOC and TE to this eect, and in de by AOC and TE to this effect, and in

accordance with the terms of the Joint Operating Agreement, it is considered that the ownership of the 50% held by

AOC and TE was passed on 30 June 2023, resulting in Tullow holding 100%. From that date, Tullow has the right to benee right to benefit

from the PI and is liable for all costs incurred going forward (except those for which the withdrawing parties remain

liable for). As the sole party, Tullow can control and direct the use of the asset from 30 June 2023. The position remained

unchanged as at 31 December 2023. Tullow accounted for this as an asset acquisition at nil cost.

The withdrawal of the partners and an upward revision to the Group’s oil prices as detailed in note 9 are considered to be

impairment assessment triggers for the asset as at 31 December 2023, and in line with its accounting policy the Group

has performed a VIU assessment. The cash lsh flows were discounted using a pre-tax nominal discount rate of 20% (2022:

20%). This resulted in an NPV signiignificantly in excess of the book value of $260.1 million. However, the Group has identiientified

the following uncertainties in respect of the Group’s ability to realise the estimated VIU; receiving and subsequently

inalifinalising an acceptable oer from a strate offer from a strategic partner and securing governmental approvals relating thereto, obtaining

inanfinancing for the project and government deliverables in form of provision of required infrastructure and isces in form of provision of required infrastructure and fiscal terms.

These items require satisfactory resolution before the Group can take a Final Investment Decision (FID). The Group

continues to progress with the farm-down process.

Due to the binary nature of these uncertainties the Group was unable to either adjust the cash lsh flows or discount

rate appropriately. It has therefore used its judgement and assessed a probability of achieving FID and therefore the

recognition of commercial reserves. This probability was applied to the VIU to determine a risk-adjusted VIU and

compared against the net book value of the asset. Certain risks have increased since 31 December 2022, predominantly

around farm-down and project inaroject financing. This has been partially oset by an intially offset by an increased equity interest in the project and

changes in oil price assumptions.

Based on this, the NPV has been revised to $242.2 million and an impairment of $17.9 million has been recognised as at

31D31 December 2023.

Should the uncertainties around the project be resolved, there will be a reversal of a previously recorded impairment.

However, if the uncertainties are not resolved there will be an additional impairment of $242.2 million. A reduction or

increase in the two-year forward curve of $5/bbl, based on the approximate range of annualised average oil price over

recent history, and a reduction or increase in the medium and long-term price assumptions of $5/bbl, based on the range

of annualised average historical prices, are considered to be reasonably possible changes for the purposes of sensitivity

analysis. Decreases to oil prices speciiefied above would increase the impairment charge by $37.9 million, whilst increases

to oil prices speciicified above would result in a credit to the impairment charge of $37.7 million. A 1% change in the pre-

tax discount rate would result in an additional impairment charge of $33.9 million. The Group believes a 1% 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’ impairments.

GuGuyanna

On 10 August 2023, Tullow announced that it had agreed to sell its total interest in Tullow Guyana B.V., which includes

the Orinduik licence (60% operated equity) in Guyana, to Eco Guyana Oil and Gas (Barbados) Limited in exchange for an

upfront cash consideration of $0.7 million and contingent consideration linked to a series of potential future milestones.

The transaction completed on 16 November 2023 and resulted in $0.7 million of gain on disposal included in Other gains

On 28 April 2023, Tullow announced that through its wholly owned subsidiary, Tullow Oil Gabon S.A., it had signed an

Asset Swap Agreement (ASA) with Perenco Oil and Gas Gabon S.A. (Perenco). Under the ASA, Tullow has agreed to

assign and transfer certain of its existing participating interests in Limande, Turnix, M’oba, Oba and 17.5% in Simba assets

to Perenco in return for the assignment and transfer by Perenco of 15% if its participating interests in Kowe (Tchatamba)

and 20% of its participating interests in DE8 licence to Tullow.

Due to the agreed neutrality of the transaction, no additional consideration is payable by either party in respect thereof.

The ASA includes provisions to ensure the neutrality of the transaction via cash adjustments for the period between

economic date and completion date.

On completion, all assets and associated liabilities relating to the existing participating interests held in Limande, Turnix,

M’Oba and Oba assets, together with 17.5% of Tullow’s interest in Simba, will be disposed. All assets impacted by the

transaction are included in the ‘Non-Operated’ Business Unit applied for segment performance reporting.

Management concluded that the asset met the IFRS 5 Held for Sale criteria on 19 July 2023, when the agreed form of the

amendment to the Tullow Protocol was submitted to the relevant Governmental Authority of the Gabonese Republic (the

Tullow Protocol is an investment convention that applies to certain Tullow licences). All other conditions precedent to the

completion of the transaction were considered reasonably certain to occur within 12 months of 19 July.

Fr vlueFair values of fnncl ssets nd lbltess of financial assets and liabilities

With the exception of the 2026 Notes and the 2025 Notes, the Group considers the carrying value of all its inag value of all its financial assets

and liabilities to be materially the same as their fair value. The fair value of the 2026 Notes and 2025 Notes as determined

using market value at 31 December 2023, was $1,327.3 million (2022: $1,364.8 million) and $458.3 million (2022: $490.0

million) respectively. These are compared to their carrying value of $1,470.9 million (2022: $1,680.0 million) and $489.0

million (2022: $792.9 million). The 2026 Notes and the 2025 Notes are categorised as level 1 in the fair value hierarchy.

No material inNo material financial assets are impaired at the balance sheet date. Allinancet date. All financial assets and liabilities with the exception of

derivatives are measured at amortised cost.

Fr vFair vlues of dervtvalues of derivative nstrumentse instruments

All derivatives are recognised at fair value on the balance sheet with valuation changes recognised immediately in the

income statement, unless the derivatives have been designated as a cash lsh flow hedge. 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.

The Group’s derivative carrying and fair values were as follows:

|  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- |
|  | 2023 | 2023 |  | 2022 | 2022 |  |

| Total liabilities | (35.0) | – | (35.0) | (186.3) | (57.9) | (244.2) |

Derivatives’ maturity and the timing of their recycling into income or expense coincide.

The following provides an analysis of the Group’s s financial instruments measured at fair value, grouped into Levels 1 to 3

based on the degree to which the fair value is observable:

Level 1: fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets

or liabilities;

Level 2: fair value measurements are those derived from inputs other than quoted prices included within Level 1 which are

observable for the asset or liability, either directly or indirectly; and

Level 3: fair value measurements are those derived from valuation techniques which include inputs for the asset or

liability that are not based on observable market data.

All the Group’s derivatives are Level 2 (2022: Level 2). There were no transfers between fair value levels during the year.

For inanciFor financial instruments which are recognised on a recurring basis, the Group determines whether transfers have

occurred between levels by re-assessing categorisation (based on the lowest-level input which is signiiignificant to the fair

value measurement as a whole) atthe ent the end of each reporting period.

Commodt prce rCommodity price rissk

The Group uses a number of derivatives to mitigate the commodity price risk associated with its underlying oil revenue.

Such commodity derivatives tend to be priced using benchmarks, such as Dated Brent, which correlate as far as possible

to the underlying oil revenue. There is an economic relationship between the hedged items and the hedging instruments

due to a common underlying, i.e. Dated Brent, between them. Forecast oil sales, which are based on Dated Brent, are

hedged with options which have Dated Brent as reference price. An increase in Dated Brent will cause the value of the

hedged item and hedging instrument to move in opposite directions. The Group has established a hedge ratio of 1:1 for

the hedging relationships as the underlying risk of the commodity derivatives is identical to the hedged risk components.

To test the hedge eectivenee effectiveness, the Group uses the hypothetical derivative method and compares the changes in the fair

value of the hedging instruments against the changes in fair value of the hedged items attributable to the hedged risks.

The Group hedges its estimated oil revenues on a portfolio basis, aggregating its oil revenues from substantially all of its

African oil interests.

As at 31 December 2023 and 31 December 2022, all of the Group’s oil derivatives have been designated as cash ash flow

hedges. TheGs. The Group’s oil hedges have been assessed to be highly eective.hly effective.

Credt rsCredit risk

The Group has a credit policy that governs the management of credit risk, including the establishment of counterparty

credit limits and specicific transaction approvals. The Group limits its counterparty credit risk on cash and cash equivalent

balances by dealing only with inanly with financial institutions with credit ratings of at least A or equivalent.

The primary credit exposures for the Group are its receivables generated by the sale of crude oil and natural gas

and amounts due from JV Partners (including in relation to their share of the TEN FPSO lease). These exposures are

managed at the corporate level. During the ing the financial year 2023, the Group’s crude sales were predominantly made to

international oil market participants including the oil majors and trading houses. In November 2023, the Group entered

into oil marketing and og and offtake contracts with Glencore for the Group’s crude oil entitlements from the Jubilee and Ten

ielfields in Ghana and the Rabi Light entitlements in Gabon. JV Partners are predominantly international major oil and gas

market participants. Counterparty evaluations are conducted utilising international credit rating agency and inand financial

assessments. Where considered appropriate, security in the form of trade inance insade finance instruments from inancial ins financial institutions

with an appropriate credit rating, such as letters of credit, guarantees and credit insurance, are obtained to mitigate

the risks.

The Group generally enters into derivative agreements with banks which are lenders under the SSRCF. The Group does

not have any signiicant cnot have any significant credit risk exposure to any single counterparty or any group of counterparties. The maximum

inanfinancial exposure due to credit risk on the Group’s ins financial assets, representing the sum of cash and cash equivalents,

investments, derivative assets, trade receivables, and receivables from Joint Venture Partners, as at 31 December 2023

was $1,373.1 million (2022: $1,438.7 million).

Foren currenc rsForeign currency risk

The Group conducts and manages its business predominantly in US dollars, the functional currency of the industry in

which it operates. The Group also purchases the functional currencies of the countries in which it operates routinely

on the spot market. From time to time the Group undertakes transactions denominated in other currencies arising

from certain operating and capital expenditure incurred in currencies other than US dollars; these exposures are often

managed by executing foreign currency inanged by executing foreign currency financial derivatives. There were no foreign currency inanco foreign currency financial derivatives in

place as at 31 December 2023 (2022: nil). Cash balances are held in other currencies to meet immediate operating and

administrative expenses or to comply with local currency regulations.

As at 31 December 2023, the only material monetary assets or liabilities of the Group that were not denominated in the

functional currency of the respective subsidiaries involved were $6.7 million in non-US dollar-denominated cash and cash

equivalents (2022: $58.1 million).

TEN FPSO

The Group’s leases balance includes the TEN FPSO, classiisified as ‘Oil and Gas production and support equipment’. During

the year, the assumption that the TEN FPSO lease term would end in April 2024, when the purchase option was assumed

to be exercised, was updated to releeflect the best estimate view that the FPSO will continue to be leased until the cessation

of production in 2032. It also assumes an exercise of the extension option.

1.  This relates to an acquisition through business combination discussed in note 15 of the 2022 Annual Report and Accounts.

Other provisions include non-income tax provisions of $38.8 million (2022: $68.3 million) and $54.9 million (2022: $48.0

million) of disputed cases and claims. Management estimates non-current other provisions would fall due between two

and ivand five years.

Non-Current other provisions includes a provision relating to a potential claim arising out of historical contractual

agreement. Further information is not provided as it will be seriously prejudicial to the Company’s interest.

The decommissioning provision represents the present value of decommissioning costs relating to the European and

African oil and gas interests. The Group has assumed cessation of production as the estimated timing for outlflow of

expenditure. However, expenditure could be incurred prior to cessation of production or after and actual timing will

depend on a number of factors including, underlying cost environment, availability of equipment and services and

allocation of capital.

The energy transition could result in decommissioning taking place earlier than anticipated. The risk on the timing of

decommissioning activities is limited, supported by production plans to fully produce ans to fully produce fields in the foreseeable future. For

Net Zero Emissions sensitivities, including acceleration of decommissioning activities, refer to page 45 of the TCFD and

note 25. Climate change and energy transition.

In 2023, after the extension of several licences in Gabon, the discount rate has increased from 3.5% to 4% for those assets

with an assumed cessation of production date post 2038. This is due to a rate dierence bate difference between the 10- and 20-year US

Treasury Bills which are used as a data source. This resulted in a decrease in the provision of $3.1 million in Gabon.

1.  This relates to an acquisition through business combination discussed in note 15 of the 2022 Annual Report and Accounts.

The majority of the Group’s deferred tax assets and liabilities are expected to be recovered over more than one year.

Deferred tax assets are recognised only to the extent it is considered probable that those assets will be recoverable. This

involves an assessment of when those deferred tax assets are likely to reverse, and a judgement as to whether or not

there will be suthere will be sufficient taxable proits available to oset the tax ae profits available to offset the tax assets when they do reverse. This requires assumptions

regarding future proitabilitfitability and is therefore inherently uncertain. To the extent assumptions regarding future proitabilitmptions regarding future profitability

change, there can be an increase or decrease in the level of deferred tax assets recognised which can result in a charge

or credit in the period in which the change occurs.

Under the TIP, senior management can be granted nil exercise price options, normally exercisable from three years (ive rmally exercisable from three years (five

years in the case of the Company’s Directors) to ten years following grant provided an individual remains in employment.

The size of awards depends on both annual performance measures and total shareholder return (TSR) over a period of up

to three years. There are no post-grant performance conditions. No dividends are paid over the vesting period; however,

it has been agreed for the TIP Awards since 2018 that an amount equivalent to the dividends that would have been paid

on the TIP shares during the vesting period if they were ‘real’ shares will also be payable on exercise of the award. There

are further details of the TIP in the Remuneration Report on pages 89 to 113.

The weighted average remaining contractual life for TIP awards outstanding at 31 December 2023 was 6.6 years.

Emploee Shre Awroyee Share Award Pln (ESd Plan (ESAP)

Most Group employees are eligible to be granted nil exercise price options, that are exercisable from three to ten years

following grant. An individual must normally remain in employment for three years from grant for the share to vest. Awards

are not subject to post-grant performance conditions. No dividends are paid over the vesting period; however, it has been

agreed for the ESAP awards granted since 2018 that an amount equivalent to the dividends that would have been paid on the

ESAP shares during the vesting period if they were ‘real’ shares will also be payable on exercise of the award.

Phantom options that provide a cash bonus equivalent to the gain that could be made from a share option (being granted

over a notional number of shares) have also been granted under the ESAP in situations where the grant of share options was

not practicable.

The weighted average remaining contractual life for ESAP awards outstanding at 31 December 2023 was 7.1 years.

2010 Sh2010 Share Optoption Pln (2010 Sn Plan (2010 SOP)

Participation in the 2010 SOP was available to most of the Group’s employees. Options have an exercise price equal to

market value shortly before grant and are normally exercisable between three and ten years from the date of the grant

subject to continuing employment.

Phantom options, providing a cash bonus equivalent to the gain that could be made from a share option, have also been

granted under the 2010 SOP in situations where the grant of share options was not practicable.

All remaining options under the SOP expired during 2023 and so there were no outstanding options under the SOP at

monthly limits. Contributions are used by the SIP trustees to buy Tullow shares (Partnership Shares) at the end of each

three-month accumulation period. The Company makes a matching contribution to acquire Tullow shares (Matching

Shares) on a one-for-one basis. Under the UK SIP, Matching Shares are subject to time-based forfeiture over three years

on leaving employment in certain circumstances or if the related Partnership Shares are sold. The fair value of a Matching

Share is its market value when it is awarded.

Under the UK SIP: (i) Partnership Shares are purchased at the lower of their market values at the start of the accumulation

period and the purchase date (which is treated as a three-month share option for IFRS 2 purposes and therefore results

in an accounting charge); and (ii) Matching Shares vest over the three years after being awarded (resulting in their

accounting charge being spread over that period).

Under the Irish SIP: (i) Partnership Shares are bought at the market value at the purchase date (which does not result

in any accounting charge); and (ii) Matching Shares vest over the two years after being awarded (resulting in their

accounting charge being spread over that period).

Tullow Executveutive Shre Pln (L Share Plan (LTIP)

Under the LTIP, senior management can be granted nil exercise price options, normally exercisable between 2.5 to 10

years following grant (with a two-year holding period in the case of the Company’s Directors). Awards granted in 2023

vest subject to Total Shareholder Return (TSR) performance conditions, with 50% of an award subject to an Absolute

TSR performance condition (where the Company’s TSR is tested against targets set by the Remuneration Committee),

and the remaining 50% subject to a relative TSR condition (where the Company’s TSR is compared to the companies

in a Selected Peer Group). Performance is measured over a ixed three-year peured over a fixed three-year period of three consecutive inacutive financial years

starting with the inting with the financial year in which the award is made. The average share price over each weekday within the

previous three months is calculated at the start and at the end of the Performance period. The TSR is calculated from

these averages. An individual must also normally remain in employment to the vesting date in order for the shares to

vest. No dividends are paid over the vesting period; however, it has been agreed for the 2023 LTIP awards that an amount

equivalent to the dividends that would have been paid on the LTIP shares during the vesting period if they were ‘real’

shares will also be payable on exercise of the award. There are further details of the 2023 Tullow Executive Share Plan

(LTIP) awards in the Remuneration Report on pages 89 to 113.

The weighted average remaining contractual life for LTIP awards outstanding at 31 December 2023 was 9.5 years.

Where Tullow acts as operator of a Joint Venture the capital commitments reported represent Tullow’s net share of

Performance guarantees are in respect of abandonment obligations, committed work programmes and certain

inancifinancialoblal obligations.

Other contingent liabilities include amounts for ongoing legal disputes with third parties where we consider the likelihood

of a cash outlow to be highflow to be higher than remote but not probable. The timing of any economic outlflow if it were to occur

would likely range between oneand ive years. e and five years.

The movement in capital commitments is predominantly due to lower capital expenditure budget in Ghana after the

start-up of Jubilee South East project in 2023.

Tullow targets being Net Zero Scope 1 and 2 emissions by 2030, on a net equity basis, with an interim target of 40%

reduction in emissions by 2025, these metrics have been included in the Group’s business plan. The Financial Statements

are based on reasonable and supportable assumptions that represent management’s current best estimate of the range

of economic conditions that may exist in the foreseeable future.

The Group has performed an assessment of the potential future impact of climate change on key elements of its

Financial Statements utilising three IEA scenarios (see TCFD on pages 38 to 47 for details).

Tullow continues to assess operating cash lsh flow (OCF) impact on our currently producing assets using the oil price

assumptions within the IEA scenarios which are detailed on pages 43 to 45 of the TCFD.

The impact of acute and chronic physical climate risks on our existing assets are also assessed and meteorological and

climate conditions are incorporated into operational design considerations, please refer to the TCFD on pages 38 to 47

for probabilities, potential exposures, and mitigations.

While carbon prices are projected to grow, there is low likelihood that there will be a substantive impact on the Group’s

core geographies in the medium term. Tullow runs shadow carbon price sensitivities for any new investment decisions

and business planning cycles, using an internal shadow carbon price of $25/tCO

e which is in line with the NZE carbon

price for other emerging market and developing economies.

To address hard to abate residual emissions, Tullow is developing a nature-based carbon osn offset project with the Forestry

Financial statements Supplementary informationStrategic report Corporate governance

#### Compn ccountn polces

As at 31 December 2023

#### () Generl nformton

Tullow Oil plc is a company incorporated in the United

Kingdom under the Companies Act. The address of the

registered oice is Tullow Oil plc, Building 9, Chiswick Park,

566 Chiswick High Road, London W4 5XT. The Financial

Statements are presented in US dollars and all values

are rounded to the nearest $0.1 million, except where

otherwise stated. Tullow Oil plc is the ultimate Parent of

the Group.

#### (b) Bss of preprton

The Company meets the deinition of a qualifying entity

under Financial Reporting Standard 100 (FRS 100)

issued by the Financial Reporting Council. The Financial

Statements have therefore been prepared in accordance

with Financial Reporting Standard 101 (FRS101) Reduced

Disclosure Framework as issued by the Financial

Reporting Council.

The following exemptions from the requirements of IFRS

have been applied in the preparation of these Financial

Statements, in accordance with FRS 101:

•  Paragraphs 45(b) and 46 to 52 of IFRS 2 Share-based

Payment (details of the number and weighted average

exercise prices of share options, and how the fair value

of goods or services received was determined).

•  IFRS 7 Financial Instruments: Disclosures.

•  Paragraphs 91 to 99 of IFRS 13 Fair Value Measurement

(disclosure of valuation techniques and inputs used for

fair value measurement of assets and liabilities).

•  Paragraph 38 of IAS 1 Presentation of Financial

Statements – comparative information requirements in

respect of certain assets.

The following paragraphs of IAS 1 Presentation of Financial

Statements:

•  10(d) (statement of cash lows).

•  111 (cash low statement information).

•  134–136 (capital management disclosures).

•  IAS 7 Statement of Cash Flows.

•  Paragraphs 30 and 31 of IAS 8 Accounting Policies,

Changes in Accounting Estimates and Errors.

•  Paragraph 17 of IAS 24 Related Party Disclosures (key

management compensation).

•  The requirements in IAS 24 Related Party Disclosures,

todisclose related party transactions entered into

between two or more members of a group. Where

relevant, equivalent disclosures have been given in the

Group accounts.

The Financial Statements have been prepared on the

historical cost basis, except for derivative inancial

instruments that have been measured at fair value.

The Company has applied the exemption from the

requirement to publish a separate proit and loss account

for the Parent Company set out in section 408 of the

Companies Act 2006.

During the year the Company made a loss of $68.0 million

(2022: $179.5 million loss).

#### (c) Gon concern

Refer to the Basis of preparation in the Accounting Policies

section of the Group accounts.

#### (d) Foren currences

The US dollar is the functional and presentational currency

of the Company. Transactions in foreign currencies are

translated at the rates of exchange ruling at the transaction

date. Monetary assets and liabilities denominated in

foreign currencies are translated into US dollars at the

rates of exchange ruling at the balance sheet date, with a

corresponding charge or credit to the income statement.

However, exchange gains and losses arising on long-term

foreign currency borrowings, which are a hedge against

the Company’s overseas investments, are dealt with

in reserves.

#### (e) Shre-bsed pments

The Company has applied the requirements of IFRS 2

Share-based Payments. The Company has share-based

awards that are equity settled and cash settled as deined

by IFRS 2. The fair value of the equity settled awards

has been determined at the date of grant of the award

allowing for the eect of any market-based performance

conditions. This fair value, adjusted by the Company’s

estimate of the number of awards that will eventually vest

as a result of non-market conditions, is expensed uniformly

over the vesting period.

The fair values were calculated using a binomial option

pricing model with suitable modiications to allow for

employee turnover after vesting and early exercise. Where

necessary, this model is supplemented with a Monte Carlo

model. The inputs to the models include: the share price at

date of grant; exercise price; expected volatility; expected

dividends; risk-free rate of interest; and patterns of exercise

of the plan participants.

For cash settled awards, a liability is recognised for the

goods or service acquired, measured initially at the fair

value of the liability. Ateach balance sheet date until the

liability is settled, and at the date of settlement, the fair

value of the liability is remeasured, with any changes in fair

value recognised in the income statement.

#### (f) Investments

Investments in subsidiaries are accounted for at cost less

any provision for impairment.

As at 31 December 2023

#### () Fnncl ssets

The Company classiies its inancial assets in the following

categories: at fair value through proit or loss; and loans

and receivables. The classiication depends on the

purpose for which the inancial assets were acquired.

Management determines the classiication of its inancial

assets at initial recognition. As of 31 December 2023, all

inancial assets were classiied at amortised cost.

Assets are classiied and measured at amortised cost when

the business model of the Company is to collect contractual

cash lows and the contractual terms give rise to cash lows

that are solely payments of principal and interest. These

assets are carried at amortised cost using the eective

interest method if the time value of money is signiicant.

Gains and losses are recognised in proit or loss when the

assets are derecognised, modiied or impaired.

(h) Fnncl lbltes

The measurement of inancial liabilities is determined by

the initial classiication.

) Fnncl lbltes t fr vlue throuh proft

orloss

Those balances that meet the deinition of being held for

trading are measured at fair value through proit or loss.

Such liabilities are carried on the balance sheet at fair value

with gains or losses recognised in the income statement.

Intercompany derivative liabilities fall under this category

of inancial instruments.

) Fnncl lbltes mesured t mortsed cost

All inancial liabilities not meeting the criteria of being

classiied at fair value through proit or loss are classiied

as inancial liabilities measured at amortised cost. The

instruments are initially recognised at their fair value net

of transaction costs that are directly attributable to the

issue of inancial liability. Subsequent to initial recognition,

inancial liabilities are measured at amortised cost using

the eective interest method.

Borrowings and trade creditors fall under this category of

inancial instruments.

#### () Shre ssue expenses

Costs of share issues are written o against the premium

arising on the issues of share capital.

#### () Fnnce costs of debt

Finance costs of debt are recognised in the proit and loss

account over the term of the related debt at a constant

rate on the carryingamount.

Interest-bearing borrowings are recorded as the proceeds

received, net of direct issue costs. Finance charges,

including premiums payable on settlement or redemption

and direct issue costs, are accounted for on an accruals

basis in the income statement using the eective interest

method and are added to the carrying amount of the

instrument to the extent that they are not settled in the

period in which they arise.

() Txton

Current and deferred tax, including UK corporation tax

and overseas corporation tax, are provided at amounts

expected to be paid using the tax rates and laws that have

been enacted or substantively enacted by the balance

sheet date. Deferred corporation tax is recognised on

all temporary dierences that have originated but not

reversed at the balance sheet date where transactions or

events that result in an obligation to pay more, or right to

pay less, tax in the future have occurred at the balance

sheet date. Deferred tax assets are recognised only to the

extent that it is considered more likely than not that there

will be suitable taxable proits from which the underlying

temporary dierences can be deducted. Deferred tax is

measured on a non-discounted basis.

Deferred tax is provided on temporary dierences

arising on acquisitions that are categorised as business

combinations. Deferred tax is recognised at acquisition

as part of the assessment of the fair value of assets and

liabilities acquired. Any deferred tax is charged or credited

in the income statement as the underlying temporary

dierence is reversed.

#### (l) Cptl mnement

The Company deines capital as the total equity of the

Company. Capital is managed in order to provide returns

for shareholders and beneits to stakeholders and to

safeguard the Company’s ability to continue as a going

concern. Tullow is not subject to any externally imposed

capital requirements. To maintain or adjust the capital

structure, the Company may adjust the dividend payment

to shareholders, return capital, issue new shares for cash,

repay debt, and put in place new debt facilities.

The Group assesses critical accounting judgements

annually. The following are the critical judgements, apart

from those involving estimations which are dealt with in

policy (af), that the Directors have made in the process of

applying the Group’s accounting policies and that have the

most signiicant eect on the amounts recognised in the

Financial Statements.

Investments (note 1)

The Company is required to assess the carrying values of

each of its investments in subsidiaries for impairment. The

net assets ofcertain of the Company’s subsidiaries are

predominantly intangible exploration and evaluation (E&E)

and property, plant and equipment assets.

Where facts and circumstances indicate that the carrying

amount of an E&E asset held by a subsidiary may exceed

its recoverable amount, by reference to the speciic

indicators of impairment of E&E assets, an impairment test

of the asset is performed by the subsidiary undertaking

and the asset is impaired by any dierence between its

carrying value and its recoverable amount. Therecognition

of such an impairment by a subsidiary is used by the

Company as the primary basis for determining whether or

not there are indications that the investment in the related

subsidiary may also be impaired, and thus whether an

impairment test of the investment carrying value needs

to be performed. The results of exploration activities are

inherently uncertain and the assessment ofimpairment

of E&E assets by the subsidiary, and that of the related

investment by the Company, is judgemental.

For property, plant and equipment, the value of assets/

ields supporting the investment value is assessed by

estimating the discounted future cash lows based on

management’s expectations of future oil and gas prices

and future costs.

In order to discount the future cash lows the Group

calculates CGU-speciic discount rates. The discount rates

are based on an assessment of a relevant peer group’s

post-tax weighted average cost of capital (WACC). The

post-tax WACC is subsequently grossed up to a pre-

tax rate. The Group then deducts any exploration risk

premium which is implicit within a peer group’s WACC and

subsequently applies additional country risk premium for

all CGUs, an element of which is determined by whether

the assets are onshore or oshore. Refer to notes 8 and 9

to the Group Financial Statements.

Where there is evidence of economic interdependency

between ields, such as common infrastructure, the ields

are grouped as a single CGU for impairment purposes.

Refer to note 1 for sensitivities.

b.  Impact of loss-making subsidiaries.

c.  Impairment reversal due to increased net asset value of a direct subsidiary.

The Company’s subsidiary undertakings as at 31 December 2023 are listed on pages 175 to 176. The principal activity of all

companies relates to oil and gas exploration, development and production.

#### Senstvtes

The value of property, plant and equipment and E&E assets supporting the investment value will be aected by the potential

future changes to oil prices and discount rates. All impairment assessments are prepared on a VIU basis using discounted

future cash lows based on 2P reserves proiles. A reduction or increase in the two-year forward curve of $5/bbl, based on

the approximate range of annualised average oil price over recent history, and a reduction or increase in the medium and

long-term price assumptions of $5/bbl, based on the range of annualised average historical prices, are considered to be

reasonably possible changes for the purposes of sensitivity analysis. Decreases to oil prices speciied in note 9 to the Group

Financial Statements would increase the investment impairment charge by $460.7 million, whilst increases to oil prices

speciied above would result in a credit to the investment impairment charge of $459.2 million. A 1% change in the pre-tax

discount rate would increase the impairment by $196.0 million. The Company believes a 1% change in the pre-tax discount

rate to be a reasonable possibility based on historical analysis of the Company’s and peer group of companies’ impairments.

Clmte chne

The value of property, plant and equipment and E&E assets supporting the investment value will be aected by

the potential future impact of Climate Change. The Company estimates that the impact on oil and carbon prices

as contained in the NZE scenarios on the value of assets held by subsidiaries could result in a potential write-o of

investments of up to $1,280.4 million. Refer to note 25 to the Group Financial Statements.

#### Note 2 Deferred tx

The Company has tax losses of $1,306.0 million (2022: $1,289.5 million) that are available indeinitely for oset against

future non-ring-fenced taxable proits in the Company. A deferred tax asset of $nil (2022: $nil) has been recognised

in respect of these losses on the basis that the Company does not anticipate making non-ring-fenced proits in the

foreseeable future.

All derivatives are recognised at fair value on the balance sheet with valuation changes recognised immediately in

the income statement. 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.

Fr vlues of dervtve nstruments contnued

The following provides an analysis of the Company’s inancial instruments measured at fair value, grouped into Levels 1 to

3 based on the degree to which the fair value is observable:

Level 1: fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets

or liabilities;

Level 2: fair value measurements are those derived from inputs other than quoted prices included within Level 1 which are

observable for the asset or liability, either directly or indirectly; and

Level 3: fair value measurements are those derived from valuation techniques which include inputs for the asset or

liability that are not based on observable market data.

All of the Company’s derivatives are Level 2 (2022: Level 2). There were no transfers between fair value levels during the year.

For inancial instruments which are recognised on a recurring basis, the Company determines whether transfers have

occurred between levels by re-assessing categorisation (based on the lowest-level input which is signiicant to the fair

value measurement asawhole) at the end of each reporting period.

#### Alterntve performnce mesures

The Group uses certain measures of performance that

are not speciically deined under IFRS or other generally

accepted accounting principles. These non-IFRS measures

include capital investment, net debt, gearing, adjusted

EBITDAX, underlying cash operating costs, free cash

low, underlying operating cash low and pre-inancing

cash low.

#### Cptl nvestment

Capital investment is deined as additions to property,

plant and equipment and intangible exploration and

evaluation assets less decommissioning asset additions,

right-of-use asset additions, capitalised share-based

payment charge, capitalised inance costs, additions

to administrative assets and certain other adjustments.

The Directors believe that capital investment is a

useful indicator of the Group’s organic expenditure on

exploration and evaluation assets and oil and gas assets

incurred during a period because it eliminates certain

accounting adjustments such as capitalised inance costs

and decommissioning assetadditions.

#### Net debt

Net debt is a useful indicator of the Group’s indebtedness,

inancial lexibility 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 deined 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 deinition 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 31 December

2023 was $185.7 million current and $721.0 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.

adjusted EBITDAX. Adjusted EBITDAX is deined as (loss)/

expense, inance costs, inance revenue, loss/(gain) on

hedging instruments, gain on bargain purchase, other

is deined as cost of sales less operating lease expense,

depletion and amortisation of oil and gas assets, underlift,

overlift and oil stock movements, share-based payment

4.   Reserves revisions in Gabon mainly relate to extension of Production licences except for Etame and Ezanga, maturation of Echira Inill wells and overall

good ield performance across all assets.

5.   Reserves revisions in Gabon also include an asset swap with Perenco, in which M’Oba, Oba, Limande, Turnix and a percentage of Simba have been

exchanged for an increased working interest in Tchatamba and the DE8 licence.

6.   Kenya contingent resources have doubled to 470mmstb, with Tullow now holding 100% of the licence, and a Field Development Plan under discussion

with government.

7.  Guyana contingent resources have been removed following agreement with our JV Partner Eco and the expiry of the Kanuku licence.

8.  A gas conversion factor of 6 mscf/boe is used to calculate the total Petroleum mmboe.

The Group provides for depletion and amortisation of tangible ixed assets on a net entitlements basis, which relects

the terms of the Production Sharing Contracts related to each ield. Total net entitlement reserves were 204.5 mmboe

at31December 2023 (31 December 2022: 219.6 mmboe).
