AS AN ENTREPRENEURIAL AND BATTLE-TESTED COMPANY THAT HAS GROWN FROM SCRATCH INTO ONE OF LATIN AMERICA'S LEADING INDEPENDENTS, WE ATTRIBUTE OUR SUCCESS TO A PROUD CULTURE BASED ON TRUST - AND WHICH IS THE CATALYST FOR OUR CONTINUOUS RECORD OF SAFE, CLEAN, NEIGHBORLY, TRANSPARENT, AND SUCCESSFUL OPERATIONS.



## Dear Fellow Shareholders:

We are pleased to report that GeoPark is a better, stronger, bigger, smarter, and more valuable Company than last year or ever before. We are vigorously marching into 2019 with a clear disciplined plan, a hungry and capable team, an arsenal of innovative tools, a new high-potential country platform (our sixth country in Latin America), and a strong wind at our backs to do even better next year.

Let’s please begin by thanking and congratulating the GeoPark team for breaking performance records across the board in 2018:

## Record oil and gas production

• Consolidated Production Up 31% to 36,027 boepd

• Colombia Production Up 31% to 28,545 boepd

## Record oil and gas reserves

• 1P Reserves Up 17% to 113.9 mmboe

• 2P Reserves Up 15% to 183.7 mmboe

• 3P Reserves Up 44% to 347.0 mmboe

## Record asset values

• Net Present Value (2P) Up 20% to $2.7 billion

• Net Asset Value (Debt-Adjusted) Per Share Up 37% to $40.1

## Record cash generation

• Record Revenues Up 82% to $601.2 million

• Adjusted EBITDA Up 88% to $330.6 million

• Free Cash Flow of $131.5 million

## Record profits

• Net Income of $102.7 million

• Earnings Per Share of $1.19

In the context of GeoPark’s relentless 16-year value-creation track record, these results demonstrate a faithful pattern of delivery that has existed since our Company was founded. And, we believe our momentum is just getting stronger and stronger.

The international investment community continued taking increased notice of GeoPark’s success and rewarded our shareholders by making us the best performing upstream oil and gas company on the New York Stock Exchange for the second year in a row (a 220% increase in two years).

Reviewing improvements to key components of our business during the year:

## Alignment

As described in our Business Guidelines (accompanying every Annual Report), GeoPark’s long-term value proposition is to build the leading independent oil and gas company in Latin America – a region of unlimited hydrocarbon resources, with sparse competition and a welcoming business environment. An advantage in creating our Company has been our consistent long-term vision and a conservative bold business plan that are supported and shared by our shareholders, board of directors, management and employee team. It is our steady focus on this bigger prize that has allowed us to build the foundation and tools needed for the long term and to push forward regardless of any short-term cycles or sentiment. All of our employees are shareholders and the management and Board (with friends and families) own approximately 50% of our Company, creating powerful alignment and incentives to perform.

## Culture

As an entrepreneurial and battle-tested company that has grown from scratch, we attribute our achievements to a proud culture based on trust – and which is the catalyst for our continuous record of safe, clean, neighborly, transparent and successful operations. We believe long-term success is defined by the underlying character and behavior of our Company, and our home-grown value system, we call SPEED, is GeoPark’s competitive advantage. It defines our success, creates positive interdependence with the communities where we operate, and ensures safe and environmentally clean operational performance. We want and expect to be the partner-of-choice, employer-of-choice and neighbor-of-choice – and our on-the-ground metrics back this up. From 2014 to date, GeoPark is the only major operator in Colombia with zero work interruptions. The Peruvian government chose GeoPark to lead them back to the upstream utilizing a novel model of development in concert with indigenous communities. In 2018,








6 Annual Report 2018 / Letter to Shareholders



GeoPark was recognized for our social commitment with an award granted by the United Nations and Colombian government.

## People

The oil business begins with people and we have purposefully built the strongest oil and gas team in Latin America. Our big ambitions require us to continuously improve our overall business and prepare for the future by increasing our capabilities and know-how in every skillset and in every country. Last year, we continued to invest in our technical, financial and management excellence and strengthen our country business unit teams by training and promoting internally and hiring experienced, high-quality professionals. Our focus on being the best has resulted in 43% of our senior management team being women. We have created a dynamic organizational and leadership framework inside GeoPark that allows us to continuously adjust and adapt to our growing enterprise and to capture the future.

## Track Record

GeoPark recognizes and, in fact, welcomes the volatility that is a permanent characteristic of our industry. We have been built to prosper and get better in an 'up-and-down' world. Our risk management approach and our ability to identify and mitigate subsurface, above-ground and macro risks to our business have resulted in a unique 16-year performance track record that has prevailed despite whatever crises have been thrown at us – whether from oil industry shocks, turbulent financial markets, or regional political turmoil. GeoPark is the only company in its peer group that can show a steady 10-year record of growth in Production, Reserves, Cash Generation, Net Present Value and Net Asset Value Per Share (with 18-26% CAGR). Our team has proven that it has reliably delivered over time and can be expected to continue to do so in the future.

## Hydrocarbons

Enduring success in our industry means being able to consistently and economically find, develop and produce oil and gas. This requires creativity, good science, discipline and the ability to take the right risks. Our team has drilled over 300 wells with a greater than 75% success rate and has discovered over 350 million boe of oil and gas. Last year, we drilled 33 wells with an 85% success rate. We increased production by 31% and exited the year with approximately 40,000 boepd. After producing over 13 million boe during the year, we replaced and grew our certified oil and gas reserves with proven (1P) reserves increasing by 17% to 114 mmboe, total proven and probable (2P) reserves increasing by 15% to 184 mmboe, and total proven, probable and possible (3P) reserves increasing by 44% to 347 mmboe.

## Cost Efficiency

Being the safest, lowest-cost operator (driller and producer) of oil and gas are the critical factors in achieving long-term industry leadership and economic success - with an even greater emphasis due to continuously volatile oil markets. GeoPark is built to prosper in a $40-50 oil price world, and our operational strength has allowed us to relentlessly drive down capital and operating costs to achieve top-performing metrics. Our 2P finding and development costs were $3.6 per boe (less than $3 per boe in Colombia), and operating costs were $8 per boe ($4 per bbl in Colombia Llanos 34). Our cost efficiency has resulted in 90% of GeoPark's production being cash-flow positive at oil prices of $25-30 per boe, providing cash flow security under almost any oil price scenario.

## Value

Our preferred basic value metric is the discounted net present value (NPV) of our proven and probable oil and gas reserves - since it encompasses the most variables impacting the recovery, cost and financial returns of our discovered oil and gas. (It does not include our significant exploration resource value.) With our new oil and gas discoveries in 2018 and our increasingly efficient cost structure, the independently-certified NPV of GeoPark's 2P oil and gas reserves (184 mmboe) increased by 20% to a value of $2.7 billion. Continuing a multi-year industry-envious capital investment efficiency record, we invested $125 million in capex and $49 million in new acquisitions in 2018 and increased our NPV by more than $450 million. On a 'per share' basis and deducting outstanding net debt, our net debt adjusted 2P NPV per share increased by 37% to $40.1 per share (or nearly $26 per share for Colombia alone). This shows the underlying value of our oil and gas assets continues to grow faster than and significantly ahead of our market share price.

## Upside

GeoPark has steadily and economically built an extensive land position across Latin America in the most prolific hydrocarbon basins, with more than five million acres in 29 blocks in 10 proven hydrocarbon basins in six countries – consisting of a risk-balanced mix of production, development, exploration and unconventional



resource projects. With our team’s oil finding abilities, this large acreage inventory is a valuable, necessary and realistic asset for our future. On our acreage, GeoPark has identified new geological plays and prospects – that is, new potential oil and gas fields – with externally-audited unrisked exploration resources of 600 million to 1.2 billion boe.

## New Opportunities

With our focus on scale, GeoPark is always in the hunt to acquire new oil and gas upstream opportunities across Latin America and we have been patient and selective in identifying and acquiring new high-quality projects on attractive terms. We begin with a technical approach to identify under-exploited proven hydrocarbon basins – considering geological, infrastructure and regulatory factors – and then work to establish strategic positions in the targeted regions. Our continuous efforts over the last 10+ years have resulted in a $4+ billion new project inventory in Colombia, Brazil, Argentina, Peru, Ecuador and Mexico. We have initiatives with the key Latin American national oil companies, which control the biggest and best hydrocarbon acreage in each country and are reevaluating their portfolios to initiate divestment programs. To enhance our position as the preferred buyer in the region, GeoPark entered into an acquisition partnership in 2018 with ONGC, the national oil company of India, to strengthen our expansion efforts. (India is the fastest-growing oil consumer in the world.)

## Self-Funding

Differentiating us from most of our industry peers, GeoPark is a self-funding growing cash-generating company – by which we mean we are getting bigger and better by paying out of our own pocket. This represents an important advantage, which is further bolstered by our capital investment efficiency. Cash flows from operating activities increased 80% to $256.2 million and Adjusted EBITDA increased by 88% to $330.6 million. We had $131.5 million of free cash flow with a 15% yield – and profits of $102.7 million. We have a history of raising capital creatively – and our balance sheet is strong with $128 million in cash and a net debt to Adjusted EBITDA ratio of 1.0X – showing our ability to effectively manage and use leverage to expand our business.

## Platform

GeoPark’s business plan and systematic expansion to date has resulted in building stable and growing independent businesses in Colombia, Chile, Brazil, Argentina and Peru – with a recent new entry into Ecuador. This large dynamic platform, painstakingly constructed over 16 years, is one of our most powerful assets – one that does not show up on a balance sheet, but which provides the foundation for our long-term growth. Each country is managed by reputable and professional local teams, with supporting production and cash flows, attractive underlying reserves and resources, and inventories of new project opportunities. Our independent country businesses benefit from the support of our overall corporate organization, which improves efficiencies, reduces costs through operational and financial synergies, controls quality, drives performance, and more effectively grows our overall company by allocating capital to the best shareholder value-adding projects.

## Country Businesses

A brief look at each of our businesses:

## Colombia Business

GeoPark is leading the strongest upstream project in Colombia, one of the most attractive onshore projects in Latin America today. In less than five years we grew from zero to become the second-largest private oil operator in the country – and are currently proving up what is being called the largest oil field discovery in Colombia in the last 20 years.

Our key asset is the Llanos 34 Block (GeoPark discovered and operated), which we have grown from 0 to 70,000+ bopd gross production – following our introduction of a new geological play type to the Llanos Basin. During 2018, after successful appraisal drilling in the Tigana and Jacana oil fields and new oil field discoveries in Chachalaca Sur and Tigui, we materially increased our Colombian certified PDP, 1P, 2P and 3P reserves by 61%, 20%, 26% and 43% to 34.7 million boe, 79.5 million boe, 111.2 million boe and 145.6 million boe respectively. Our 2P reserve life index reached 10.7 years and the reserve replacement ratio was 321%. Our 1P NPV and 2P NPV in Colombia increased to $1.4 billion and $1.9 billion respectively.

Llanos 34 is a highly attractive, low risk, low cost and high netback block which provides a large-scale profitable production base even in low oil price environments. Due to the expertise of our local teams, net finding and development costs (F&D costs) for 2018 were just $2.9 per boe (2P). We have a big inventory of well sites (80+) to continue growing production, and well economics with three digit IRRs and six-month paybacks (assuming a $50-55 per barrel Brent oil price).



Aguada Baguales Block, Neuquen, Argentina



Our return on capital in Llanos 34 is highly profitable and beats almost any North American conventional or unconventional play.

In a constant effort to reduce costs and improve netbacks, we constructed a new 30 km flowline to connect Llanos 34 to the main Colombian pipeline infrastructure which will become operational in early 2019.

During 2018, GeoPark also added new acreage adjacent to Llanos 34 and acquired LG's 20% equity interest in our Colombian subsidiary, which owns our participation in Llanos 34.

## Peru Business

GeoPark continues working to prepare for the development of the Morona Block. This project has become emblematic for Peru and, because of our operating, environmental and community track record, GeoPark was selected as the company to lead Peropero back to the upstream business and to operate this important and complex project with a 75% working interest. We are actively engaged with members of the communities and federations in the area of direct influence to cooperate on the Environmental Impact Assessment, which was submitted in 2018. The Smithsonian Institution of Washington DC entered into a partnership with GeoPark to study and monitor the biodiversity of the focus area.

Morona is a large block in the proven Marañon Basin with a large upside potential (approximately 300-500 million boe) with several high-impact plays and prospects. The block’s key asset is the Situche Central light oil field, which was discovered and proven up by two wells (which tested at a combined rate of 7,500 bopd), and which has certified gross 3P reserves of 198.3 million barrels (with a gross NPV of $2+ billion) and the opportunity for near-term cash flow.



Morona represents an important project for GeoPark that significantly increases our overall inventory of reserves and exploration resources and can contribute to our long-term durable growth. GeoPark has designed a phased work program that is expected to put the Situche Central field into production initially through a long-term test to begin generating cash flow – with ‘first oil’ targeted for 2020.

## Argentina Business

Our team is continuing to strengthen our position in Argentina, where it has a proven history of exploration success.

In March 2018, we acquired a 100% working interest in and operatorship of three new blocks (Aguada Baguales, El Porvenir and Puerto Touquet) in the heart of the Neuquen Basin with production, development, exploration and unconventional resource potential. The blocks are currently producing 2,300-2,400 boepd and were acquired at a value of $4 per boe 2P reserves. Exploration of a new tight gas play began in early 2019. In addition to its attractive upside potential, this acquisition represents a good fit with our existing platform in Argentina with the opportunity for future cost savings and operational synergies.

GeoPark also entered into a partnership with YPF, the national oil company of Argentina, on the Los Parlamentos block – a large high-potential exploration block in the Neuquen Basin with both conventional and unconventional prospects.

## Brazil Business

Our Brazil business represents a strategic base with a fully developed, secure, cash flow-producing asset (a non-operated interest in the Manati field, one of Brazil’s largest producing gas fields, operated by Petrobras) and 7 exploration blocks in onshore mature proven hydrocarbon basins (Potiguar, Reconcavo, and Sergipe Alagoas). GeoPark is currently preparing to test a new exploration well drilled in the Reconcavo Basin.

GeoPark also has identified attractive onshore and shallow offshore hydrocarbon opportunities in Brazil, and is working with Petrobras in its ongoing divestment efforts.



## Chile Business

GeoPark is Chile’s first private oil and gas producer. We built the business from a flat-footed start-up in 2006 to a solid business with current production of approximately 2,800 boepd (80% gas, 20% oil), 2P reserves of 24.7 million boe and 5 blocks with 0.8 million acres, consisting of approximately 300-800 million boe of gross exploration and unconventional resources. Over 20 million boe have already been produced by GeoPark in Chile and we divested 20% of our project in 2011 for approximately $150 million. This interest was recently re-acquired by GeoPark in November 2018.

In 2018, we discovered the Jauke gas field in the Fell Block, which is part of the large Dicky geological structure, which has the potential for multiple development drilling opportunities, some of them to be tested in 2019.

## Ecuador Business

In March 2019, GeoPark was awarded two low-risk high-potential exploration blocks in north-eastern Ecuador in the Oriente Basin. Both blocks are covered with 3D seismic and are adjacent to multiple producing oil fields and existing infrastructure. Ecuador has Latin America’s third-largest oil reserves and the Oriente Basin is producing over 500,000 bopd, with infrastructure with spare capacity and a well-developed service industry. The award of these blocks is subject to regulatory approval and contract execution – and operational start-up is targeted for late 2019 or early 2020.






## Outlook

GeoPark has developed and proven-up a highly effective and robust capital allocation methodology to manage its six-country portfolio. This system enables us to review and select from a wide range of projects generated by each business unit team with different returns, potentials, risks, sizes, timelines and geographies. It ensures that capital is always directed to our top value-adding projects after ranking them on technical, strategic and economic criteria. It creates a healthy competition between our different business units which further helps drive performance. It also provides greater security in volatile markets by allowing us to easily add or remove projects depending on oil prices and project performance – and to fine-tune our desired risk exposure.

Our 2019 work and investment program targets a $220-240 million capital investment program (considering Brent oil prices of $65-75 per barrel) and is fully funded by cash flows. As always, our flexible work program includes an accelerated case for higher oil prices and a reduced program for lower oil prices.
The 2019 work program provides for:

• 35+ gross well drilling program targeting production growth of 15%
• 27-30 gross well development, appraisal and exploration drilling program in the Llanos Basin in Colombia

• 6-7 gross well exploration and development drilling program in the Neuquen Basin in Argentina in operated and non-operated blocks
• Early production facilities in the Morona Block in the Marañon Basin in Peru with the goal of putting the Situche Central light oil field into production by 2020, subject to approval of the Environmental Impact Assessment

• 2-3 gross well exploration and development drilling program on the Fell Block in the Magallanes Basin in Chile

• 1-2 gross well shallow exploration drilling program in the onshore Reconcavo and Potiguar Basins in Brazil

## BUSINESS APPROACH AND GUIDELINES

## Strategic Context

GeoPark’s objective is to create value by building the leading Latin American upstream independent oil and gas company. By this, we mean an action-oriented, persistent, aware and caring company with the best ‘shareholder value-adding’ oil and gas assets.

We believe the energy business – specifically the upstream oil and gas industry – is one of the most exciting, necessary, and economically-rewarding businesses today. No undertaking or society can advance without the supply of energy, and energy remains the critical element in allowing people to better their lives. Much of the world still lacks adequate energy supplies for the most basic needs and demand is continually increasing. Although new exciting technologies and sources are being developed, oil and gas is the most reliable energy source and will be required to support over half of our planet’s continuous and rising energy needs far into this century.

We believe the best places for us to find and develop hydrocarbons are in areas around the world where oil and gas have already been discovered, but which for economic, technical, funding or other reasons have been inadequately developed or prematurely abandoned. These projects have proven hydrocarbon systems, valuable technical information, existing infrastructure, and, in many cases, unexploited low-risk exploration and re-development opportunities. By applying new technology and investment, creating stable markets and better economic conditions, and/or more efficient operations, an under-performing or bypassed asset can be converted into an attractive economic project. Work in these proven areas also frequently opens up exciting new hydrocarbon resources in new geological play types and formations.

We are focused on Latin America because of the abundance of these types of opportunities throughout the region. Latin America ranks as one of the highest potential hydrocarbon resource regions in the world and its economies are thirsty for new energy. Historically, it has been dominated by larger major and national oil companies, with the presence of only a modest number of more-agile independent companies. North America is home to thousands of independent oil and gas operators, whereas Latin America, an area substantially larger and with greater resource potential, has only a handful of independents taking advantage of available opportunities. In contrast to many areas of the world, the environment and resources for operating and funding a business are welcoming and increasingly more feasible. Furthermore, numerous good oil and gas assets in Latin America are available, undervalued and at very attractive prices now.

GeoPark has been conservatively built for the long term. We did not




start with a short term ‘exit strategy’ in mind and we have focused on building a team and sustainable business. Our approach has required patience in order to create the necessary foundation, but it has enabled us to stay solidly ‘in the game’ and be positioned to now have the chance to grab the bigger prizes.

The founders and our management team have a substantial part of our net worth invested in GeoPark. (The CEO founder has never sold a share of GeoPark stock.) The management team has no special class of stock or arrangements that benefit us differently from any other shareholder other than our salaries and stock performance incentive programs. The entire GeoPark team (100% of our employees have received GeoPark share awards) is solidly aligned with all of our shareholders to build real and enduring value for every share of GeoPark.

## Opportunity Enhancement and Risk Diversification

By its very nature, the upstream oil and gas business represents the undertaking of risk in search of significant rewards. To succeed, an oil and gas company must effectively identify and manage prevailing risks and uncertainties to capture the available rewards. We believe this to be one of GeoPark's key capabilities; and our year-over-year track record is evidence of our success in effectively balancing risk among the subsurface, geological, funding, organizational, market, price, partner, shareholder, regulatory and political environments. For example, GeoPark was able to respond constructively to the 2008/9 financial crisis and, again, to the oil price volatility of 2015-2016.

We believe the best results in the upstream business are achieved with a larger scale portfolio approach with multiple attractive projects in multiple regions managed by talented oil and gas teams. This diversification reflects both a defensive and offensive approach. It is protective of any downside because the collective strength of our projects limits the negative impact of any underperforming asset or timing delay. It also has an exciting multiplier effect on the potential upside because of the increased number of opportunities independently marching ahead. These represent important advantages given the nature of the oil exploration and production business.

Our country businesses are managed by experienced local professionals and teams with respected reputations. They know both the specific subsurface rocks and conditions and the above-ground operating and business environments in each region and give us the characteristics of a local company. Our pride and care in



how we act and perform in our home regions are key elements of our success.

These generally independent businesses are further enhanced by being tied together by an overall corporate organization, which improves efficiencies, reduces costs with operational and financial synergies, controls quality, and can more effectively raise capital for our projects. It also is a source for new technologies and ideas to spread from one region to another. For example, our team introduced a new geological play-type to the Llanos Basin in Colombia (an area that has been explored for more than 75 years) that resulted in multiple new oil field discoveries, and new oil technology to the Magallanes Basin in Chile.

Importantly, through effective and controlled capital allocation, our projects within each country business can be ranked against each other on economic, technical and strategic criteria and, therefore, ensure our capital resources flow to the highest performing and most attractive projects.

We believe this business approach makes GeoPark a more attractive investment vehicle for all our shareholders – with a strong foundation to minimize any downside, a big upside through multiple growth opportunities, and an overall organizational system to more efficiently run and grow the individual businesses. GeoPark’s model allows our investors to be exposed to and benefit from the results of multiple supporting and aligned businesses across diverse geologies and geographies.

## Capabilities

Our experience in the oil and gas business has repeatedly demonstrated the need for good people with commitment and real oil and gas know-how. We believe in and have experienced the amazing capacity of people to excel in an environment of expanding opportunity and trust. GeoPark is blessed to have an incredible group of men and women who truly work day and night to make us better in every way. Our results speak to the daily heroics (mostly unseen) by our team that keep us together and have moved us consistently closer to our goals.

Our record of delivery is based on three fundamental and distinct skill sets – as Explorers, Operators and Consolidators – which we deem critical for enduring success in the oil and gas business. Our team has consistently demonstrated the science and creativity to find hydrocarbons in the subsurface, but also the muscle and experience to get the oil and gas out of the ground and profitably to market. Our attractive asset portfolio is evidence of our ability to acquire good projects in the right basins in the right countries with the right partners and at the right price.

Today, we have an amazing team of employees from Chile, Colombia, Brazil, Peru and Argentina – each of whom joined GeoPark with the purpose of building a unique and special company that is prepared to handle challenges and seize opportunities. As a quickly growing company, we have repeatedly seen individuals step up to the new responsibilities presented – and we have a deep and powerful leadership team taking GeoPark to the next level.

The international upstream oil and gas business is not for the fainthearted or easily discouraged. Time-after-time, the GeoPark team has been able to push ahead to find solutions where often others have given up or failed. This is the engine and fire of our growth and the true long-term intangible value of our Company. We are immensely grateful to all these men and women for their professionalism, discipline, unity and heart.

## New Projects and Countries

We are excited about potential new business opportunities in Latin America with its high resource potential, attractive business environment, and limited competition. We are actively pursuing new projects in targeted proven hydrocarbon basins throughout the region – selected in consideration of geological, infrastructure and regulatory factors – with our principal efforts in Colombia, Brazil, Chile, Peru, Argentina, Ecuador and Mexico.

With our overall growth targets and portfolio approach, new project acquisitions are an important part of our business. Our acquisition efforts begin with a technical approach to define the hydrocarbon basins where our geological and engineering teams identify an attractive potential. After screening for political risks, our new business teams proactively ‘scratch and dig’ to locate interests or opportunities within those areas and to establish a position. It is










a long-term and continuous effort and we have been building an attractive inventory of new projects in the region over the last ten years, aided by our team’s 25+ year experience in Latin America.

Our focus is always to build a larger-scale balanced portfolio that includes lower-risk short term cash flow generating properties, mid-term medium-risk development projects, and longer term higher-risk big upside projects. This permits steady, secure growth with an opportunity for accelerated high growth ‘home-runs’ from the bigger projects.

Good oil and gas partners are a key element of our new business efforts and we like to balance our acquisition risk by including experienced partners in our new projects. We operated a strategic alliance with LG of Korea to acquire upstream assets and the International Finance Corporation (IFC) of the World Bank has been a long-term principal shareholder of (and sometimes lender to and working interest partner of) GeoPark. [In 2018, we established a long-term strategic partnership with ONGC, the national oil company of India, to build a large-scale portfolio of upstream assets across Latin America.] We also have developed long-term relationships with the national oil companies where we operate, such as with ENAP in Chile, Ecopetrol in Colombia, Petrobras in Brazil, YPF in Argentina, Petroperu in Peru, and Petroamazonas in Ecuador.

Critical to the success of any new project is to conduct a thorough technical and economic analysis prior to acquiring any new asset. We make sure we understand the project, its risks and its value – and we buy right. It is difficult to turn a faulty or overpriced project into a good business. Following intensive geological, geophysical, engineering, operational, legal and financial analyses and due diligence, we perform a detailed discounted cash flow (DCF) valuation. We also consider the option value or strategic benefits of a project when entering a new region. We do not buy assets on simplified ‘$ per barrel’ metrics which we believe do not properly account for multiple factors (including technical, cost, tax, and time) that impact the economics of oil and gas projects. We also avoid markets or ‘bubbles’ when assets are over-priced.

## Culture

'Creating Value and Giving Back' is our motto and represents GeoPark's market-based approach to align our business objectives with our core values and responsibilities. Our in-house designed program, titled SPEED, targets and integrates the critical elements – Safety, Prosperity, Employees, Environment and Community Development – necessary to make our total business plan work. Only by succeeding equally in each of these interdependent areas can we realize our overall success and ambitions. This is important in every country where we operate, and we make every effort to achieve the most effective governance, full compliance and consistent transparency with all relevant authorities. Not only does this allow us to be a more successful business enterprise over the long term, it reflects our pride in carrying out an important mission in the right way. The men and women of GeoPark care passionately about how our Company acts – both internally and externally – and we all consider our culture to be our core asset and the prime source of our past success and future opportunity.

The world is continuously moving in a more regulated direction with higher expectations, and to be able to operate in this new environment is a fundamental part of business today. We believe that GeoPark’s ability to meet these challenges and perform to or beyond these ever-increasing standards represents a competitive advantage for the future. For example, the results from and impact on the communities of our overall work and efforts in Chile and Colombia provided the rationale and support for the government and regional community to encourage us to expand our project into new areas. The World Bank’s IFC, a founding shareholder, has been a constructive force in helping us operate and manage our business in consideration of the environment and communities around us. The IFC further assisted us by carrying out annual audits and physical site visits of both our regulatory compliance and best-practices approach.

## Financial statements

## Our consolidated financial statements

This annual report includes our audited consolidated financial statements as of December 31, 2018 and 2017 and for each of the years ended December 31, 2018, 2017 and 2016 (hereinafter “Consolidated Financial Statements”).

Our Consolidated Financial Statements are presented in US$ and have been prepared in accordance with International Financial Reporting Standards ("IFRS"), as issued by the International Accounting Standards Board ("IASB").

Our Consolidated Financial Statements have been audited by Price Waterhouse & Co. S.R.L., Argentina ("PwC"), a member firm of PricewaterhouseCoopers Network, an independent registered public accounting firm, as stated in their report included elsewhere in this annual report.

Our fiscal year ends December 31. References in this annual report to a fiscal year, such as “fiscal year 2018,” relate to our fiscal year ended on December 31 of that calendar year.

## Non IFRS financial measures

## Adjusted EBITDA

Adjusted EBITDA is a supplemental non-IFRS financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, to assess the performance of our Company and the operating segments.

We define Adjusted EBITDA as profit for the period before net finance cost, income tax, depreciation, amortization and certain non-cash items such as impairment charges or impairment reversals, write-offs of unsuccessful exploration and evaluation assets, accrual of stock options and stock awards, unrealized gains in commodity risk management contracts and bargain purchase gain on acquisition of subsidiaries. Adjusted EBITDA is not a measure of profit or cash flows as determined by IFRS.

We believe Adjusted EBITDA is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from profit for the period in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, profit for the period or cash flows from operating activities as determined in accordance with IFRS or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure and significant and/or recurring write-offs, as well as the historic costs of depreciable assets, or unrealized gains in commodity risk management contracts, none of which are components of Adjusted EBITDA. Our computation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.

For a reconciliation of Adjusted EBITDA to the IFRS financial measure of profit for the year, see Note 6 to our Consolidated Financial Statements as of and for the years ended 2018, 2017 and 2016.



## Oil and gas reserves and production information

## DeGolyer and MacNaughton 2018 Year-end Reserves Report

The information included elsewhere in this annual report regarding estimated quantities of proved reserves in Colombia, Chile, Brazil, Argentina and Peru is derived, in part, from estimates of the proved reserves as of December 31, 2018. The reserves estimates described herein are derived from the DeGolyer and MacNaughton Reserves Report ("D&M Reserves Report"), which was prepared for us by the independent reserves engineering team of DeGolyer and MacNaughton and is included as an exhibit to this annual report.

Market data, other statistical information, information regarding recent developments in Chile, Colombia, Brazil, Peru and Argentina and certain industry forecast data used in this annual report were obtained from internal reports and studies, where appropriate, as well as estimates, market research, publicly available information and industry publications. Industry publications generally state that the information they include has been obtained from sources believed to be reliable, but that the accuracy and completeness of such information is not guaranteed. Similarly, internal reports and studies, estimates and market research, which we believe to be reliable and accurately extracted by us for use in this annual report, have not been independently verified.

## ITEM 3. KEY INFORMATION

## A. Selected financial data

We have derived our selected historical balance sheet data as of December 31, 2018 and 2017 and our consolidated statement of income and cash flow data for the years ended December 31, 2018, 2017 and 2016 from our consolidated financial statements included elsewhere in this annual report, which have been audited by PwC. We have derived our selected balance sheet data as of December 31, 2016, 2015, and 2014 and our consolidated statement of income and cash flow data for the years ended December 31, 2015 and 2014 from our consolidated financial statements not included in this annual report.

During 2015, Management changed the presentation of the Consolidated Statement of Income by reordering the profit and loss line items, eliminating gross profit and presenting depreciation and write-off of unsuccessful efforts as separate line items. This change is intended to provide readers of our financial statements with more relevant information and a better explanation of the elements of performance. This change has been applied to comparative figures for 2014 presented in this document.

We maintain our books and records in US$ and prepare our Consolidated Financial Statements in accordance with IFRS.

In Colombia, Chile, Argentina and Peru, our functional currency is the U.S. dollar. In Brazil, our functional currency is the real.

Our operations in Brazil accounted for 12% and 8% of our consolidated assets and 10% and 5% of our revenues for the years ended December 31, 2017 and 2018, respectively. This portion of our business is exposed to losses that may arise from currency fluctuation, as a significant amount of our revenues, operating costs, administrative expenses and taxes in Brazil are denominated in reais.

The real may depreciate or appreciate substantially against the U.S. dollar. We recorded exchange rate losses amounting to US$5.9 million for the year ended December 31, 2018, principally due to the devaluation of the real and its impact on US dollar denominated intercompany debt cancelled by our Brazilian subsidiary in October 2018. We recorded exchange rate losses amounting to US$1.3 million for the year ended December 31, 2017 as a result of the devaluation of the local currency in our Brazilian subsidiary which was mainly generated by the credit facility with Itaú BBA International plc that we incurred on March 31, 2014 to acquire Rio das Contas, which we repaid in September 2017. See “—D. Risk factors—Risks relating to our business—Our results of operations could be materially adversely affected by fluctuations in foreign currency exchange rates.”

Exchange rate fluctuation may affect the US$ value of any distributions we make with respect to our common shares. See “—D. Risk factors—Risks relating to our business—Our results of operations could be materially adversely affected by fluctuations in foreign currency exchange rates.”

Not applicable.

## C. Reasons for the offer and use of proceeds

Not applicable.

## D. Risk factors

Our business, financial condition and results of operations could be materially and adversely affected if any of the risks described below occur. As a result, the market price of our common shares could decline, and you could lose all or part of your investment. This annual report also contains forward-looking statements that involve risks and uncertainties. See “Forward-Looking Statements.” The risks below are not the only ones facing our Company. Additional risks not currently known to us or that we currently deem immaterial may also adversely affect us.

## Risks relating to our business

A substantial or extended decline in oil, natural gas and methanol prices may materially adversely affect our business, financial condition or results of operations.
The prices that we receive for our oil and natural gas production heavily influence our revenues, profitability, access to capital and growth rate. Historically, the markets for oil, natural gas and methanol (which have influenced prices for almost all of our Chilean gas sales) have been volatile and will likely continue to be volatile in the future. International oil, natural gas and methanol prices have fluctuated widely in recent years and may continue to do so in the future.

The prices that we will receive for our production and the levels of our production depend on numerous factors beyond our control. These factors include, but are not limited, to the following:

• global economic conditions;

• changes in global supply and demand for oil, natural gas and methanol;

• the actions of the Organization of the Petroleum Exporting Countries ("OPEC");

• political and economic conditions, including embargoes, in oil-producing countries or affecting other countries;

• the level of oil- and natural gas-producing activities, particularly in the Middle East, Africa, Russia, South America and the United States;

• the level of global oil and natural gas exploration and production activity;

• the level of global oil and natural gas inventories;

• the price of methanol;

• availability of markets for natural gas;

• weather conditions and other natural disasters;

• technological advances affecting energy production or consumption;

• domestic and foreign governmental laws and regulations, including environmental, health and safety laws and regulations;

• proximity and capacity of oil and natural gas pipelines and other transportation facilities;

• the price and availability of competitors’ supplies of oil and natural gas in captive market areas;

• quality discounts for oil production based, among other things, on API, sulphur and mercury content;

• taxes and royalties under relevant laws and the terms of our contracts;

• our ability to enter into oil and natural gas sales contracts at fixed prices;

• the level of global methanol demand and inventories and changes in the uses of methanol;

• the price and availability of alternative fuels; and

• future changes to our hedging policies.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil, natural gas and methanol price movements. For example, recently, oil and natural gas prices have fluctuated significantly. From January 1, 2014 to December 31, 2018, Brent spot prices ranged from a low of US$27.9 per barrel to a high of US$118.9 per barrel, Henry Hub natural gas average spot prices ranged from a low of US$1.7 per mmbtu to a high of US$6.0 per mmbtu, US Gulf methanol spot barge prices ranged



from a low of US$250.0 per metric ton to a high of US$635.1 per metric ton. Furthermore, oil, natural gas and methanol prices do not necessarily fluctuate in direct relationship to each other.

For the year ended December 31, 2018, 91% of our revenues were derived from oil. Because we expect that our production mix will continue to be weighted towards oil, our financial results are more sensitive to movements in oil prices.

As of December 31, 2018, natural gas comprised 9% of our revenues. A decline in natural gas prices could negatively affect our future growth, particularly for future gas sales where we may not be able to secure or extend our current long-term contracts.

Lower oil and natural gas prices may impact our revenues on a per unit basis, and may also reduce the amount of oil and natural gas that can be produced economically. In addition, changes in oil and natural gas prices can impact the valuation of our reserves and, in periods of lower commodity prices, we may curtail production and capital spending or may defer or delay drilling wells because of lower cash generation. Lower oil and natural gas prices could also affect our growth, including future and pending acquisitions. A substantial or extended decline in oil or natural gas prices could adversely affect our business, financial condition and results of operations.

For example, during 2014 and 2015, we evaluated the recoverability of our fixed assets affected by the oil price decline and recorded an impairment of non-financial assets amounting to, respectively, US$9.4 million and US$149.6 million. US$5.7 million of the impairment recorded in 2015 was reversed in 2016 due to increased estimated market prices for 2017 and 2018 and improvements in cost structure. After conducting an impairment test procedure for the year ended December 31, 2018 we recognized US$11.5 million as reversal of impairment losses due to increases in estimated market prices and improvements in cost structure, and also the known fair value less costs of disposal of the La Cuerva and Yamu Blocks in Colombia, partially offset by an impairment loss in Chile of US$6.5 million due to the termination of the sales agreement for the TdF's blocks, with no renovation in place as of the date of this annual report. See Note 36 to our Consolidated Financial Statements for details regarding oil price scenarios, discount rates considered and sensitivity analysis affecting the impairment charges.

Continuing our hedging strategy, we entered into derivative financial instruments to manage exposure to oil price risk. These derivatives were zero-premium collars or zero premium three way hedges (put, spread and call) and were placed with major financial institutions and commodity traders. We entered into the derivatives under ISDA Master Agreements and Credit Support Annexes, which provide credit lines for collateral posting thus alleviating possible liquidity needs under the instruments and protecting us from potential non-performance risk by our counterparties. See Note 8 to our Consolidated Financial Statements for details regarding Commodity Risk Management Contracts.

## The oil price crisis has impacted our operations and corporate strategy.

We face limitations on our ability to increase prices or improve margins on the oil and natural gas that we sell. As a consequence of the oil price crisis which started in the second half of 2014 (WTI and Brent, the main international oil price markers, fell by more than 60% between August 2014 and March 2016), the Company took decisive measures to ensure its ability to both maximize ongoing projects and to preserve its cash.

Funding our anticipated capital expenditures relies in part on oil prices remaining close to our estimates or higher levels and other factors to generate sufficient cash flow. Low oil prices affect our revenues, which in turn affect our debt capacity and the covenants in our financing agreements, as well as the amount of cash we can borrow using our oil reserves as collateral, the amount of cash we are able to generate from current operations and the amount of cash we can obtain from prepayment agreements. If we are not able to generate the sales which, together with our current cash resources, are sufficient to fund our capital program, we will not be able to efficiently execute our work program, which would cause us to further decrease our work program and would harm our business outlook, investor confidence and our share price.

In addition, actions taken by the company to maximize ongoing projects and to reduce expenses, including renegotiations and reduction of oil and gas service contracts and other initiatives such as cost cutting may expose us to claims and contingencies from interested parties that may have a negative impact on our business, financial condition, results of operations and cash flows. If oil prices are lower than expected, we may be unable to meet our contractual obligations with oil and service contracts and our suppliers. Equally, those third parties may be unable to meet their contractual obligations to us as a result of the oil price crisis, impacting on our operations.

In budgeting for our future activities, we have relied on a number of assumptions, including, with regard to our discovery success rate, the number of wells we plan to drill, our working interests in our prospects, the costs involved in developing or participating in the development of a prospect, the timing of third-party projects and our ability to obtain needed financing with respect to any further acquisitions and the availability of both suitable equipment and qualified personnel. These assumptions are inherently subject to significant business, political, economic, regulatory, environmental and competitive uncertainties, conditions in the financial markets, contingencies and risks, all of which are difficult to predict and many of which are beyond our control. In addition, we opportunistically seek out new assets and acquisition targets to complement our existing operations and have financed such acquisitions in the past through



the incurrence of additional indebtedness, including additional bank credit facilities, equity issuances or the sale of minority stakes in certain operations to our partners. We may need to raise additional funds more quickly if one or more of our assumptions prove to be incorrect or if we choose to expand our hydrocarbon asset acquisition, exploration, appraisal or development efforts more rapidly than we presently anticipate, and we may decide to raise additional funds even before we need them if the conditions for raising capital are favorable. The ultimate amount of capital that we will expend may fluctuate materially based on market conditions, our continued production, decisions by the operators in blocks where we are not the operator, the success of our drilling results and future acquisitions. Our future financial condition and liquidity will be impacted by, among other factors, our level of production of oil and natural gas and the prices we receive from the sale thereof, the success of our exploration and appraisal drilling program, the number of commercially viable oil and natural gas discoveries made and the quantities of oil and natural gas discovered, the speed with which we can bring such discoveries to production and the actual cost of exploration, appraisal and development of our oil and natural gas assets.

Unless we replace our oil and natural gas reserves, our reserves and production will decline over time. Our business is dependent on our continued successful identification of productive fields and prospects and the identified locations in which we drill in the future may not yield oil or natural gas in commercial quantities.

Production from oil and gas properties declines as reserves are depleted, with the rate of decline depending on reservoir characteristics. Accordingly, our current proved reserves will decline as these reserves are produced. As of December 31, 2018, our reserves-to-production (or reserve life) ratio for net proved reserves in Colombia, Chile, Argentina, Brazil and Peru was 8.2 years. According to estimates, if on January 1, 2019 we ceased all drilling and development activities, including recompletions, refracs and workovers, our proved developed producing reserves base in Colombia, Chile, Brazil, Argentina and Peru would decline 34% during the first year.

Our future oil and natural gas reserves and production, and therefore our cash flows and income, are highly dependent on our success in efficiently developing our current reserves and using cost-effective methods to find or acquire additional recoverable reserves. While we have had success in identifying and developing commercially exploitable fields and drilling locations in the past, we may be unable to replicate that success in the future. We may not identify any more commercially exploitable fields or successfully drill, complete or produce more oil or gas reserves, and the wells which we have drilled and currently plan to drill within our blocks or concession areas may not discover or produce any further oil or gas or may not discover or produce additional commercially viable quantities of oil or gas to enable us to continue to operate profitably. If we are unable to replace our current and future production, the value of our reserves will decrease, and our business, financial condition and results of operations will be materially adversely affected.

We derive a significant portion of our revenues from sales to a few key customers.

In Colombia, for the year ended December 31, 2018, we made 99% of our oil sales from operated blocks to C.I. Trafigura Petroleum Colombia S.A.S., a leading commodity trading and logistics company (“Trafigura”), representing 82% of our consolidated revenues for the same period. Considering the expiration of our long-term contract with Trafigura in December 2018, we have started diversifying our client base in Colombia, allocating sales on a competitive basis to leading industry participants including traders and other producers. The contracts extend through 2019 with no long-term delivery commitments in place. Delivery points include wellhead and other locations in the Colombian pipeline system. We manage the counterparty credit risk associated to sales contracts by including early payment conditions which minimize our exposure.

In Chile, 100% of our crude oil and condensate sales are made to ENAP. For the year ended December 31, 2018, sales to ENAP represented 3% of our total revenues. ENAP imports the majority of the oil it refines and partially supplements those imports with volumes supplied locally by its own operated fields and those operated by us. On April 21, 2017, we renewed our sales agreement with ENAP. As part of this agreement, ENAP has committed to purchase our oil production in the Fell Block in the amounts that we produce, subject to the limitation of available storage capacity at the Gregorio Terminal. The sales agreement provides us with the option to interrupt sales to ENAP periodically if conditions in the export markets allow for more competitive price levels. While the agreement renews automatically on an annual basis, we typically make an annual revision jointly with ENAP. In addition, for the year ended December 31, 2018, almost all of our natural gas sales in Chile were made to Methanex Chile SpA., the Chilean subsidiary of the Methanex Corporation (“Methanex”), a leading global methanol producer, under a long-term contract (the “Methanex Gas Supply Agreement”), which will expire on December 31, 2026. Sales to Methanex represented 3% of our consolidated revenues for the year ended December 31, 2018.

In Brazil, all of our gas and condensate produced in the Manati Field is sold to Petróleo Brasileiro S.A. ("Petrobras"), the operator of the Manati Field, pursuant to a long-term gas off-take contract and a condensate purchase agreement. See "Item 4. Information on the Company—B. Business Overview—Significant Agreements—Brazil—Petrobras Natural Gas Purchase Agreement."

In Argentina, all the gas produced in 2018 was sold to Grupo Albanesi, a leading Argentine privately held conglomerate focused on the energy market that offers natural gas and power supply and transport services to its customers. We have an annual agreement effective from May 2018 through April 2019. Gas sales in Argentina represented 1% of our total revenue. The oil sales in Argentina are diversified across clients and delivery points: i) 30% of the oil



produced in Argentina (2% of our total revenue) is sold locally in Neuquén Province, delivered at well-head; and ii) 70% of the oil produced in Argentina (3% of our total revenues) is sold to major Argentine refineries, and delivered via pipeline.

If any of our buyers were to decrease or cease purchasing oil or gas from us, or if any of them were to decide not to renew their contracts with us or to renew them at a lower sales price, this could have a material adverse effect on our business, financial condition and results of operations.

## Our results of operations could be materially adversely affected by fluctuations in foreign currency exchange rates.

Although a majority of our net revenues is denominated in US$, unfavorable fluctuations in foreign currency exchange rates for certain of our expenses in Colombia, Chile, Brazil, Argentina and Peru could have a material adverse effect on our results of operations. A portion of the cost reductions that we achieved in 2015 and 2016 (as compared to 2014) were related to the depreciation of local currencies, including mainly the Col$, the Ch$ and the Brazilian real. An appreciation of local currencies can increase our costs and negatively impact our results from operations.

Because our Consolidated Financial Statements are presented in US$, we must translate revenues, expenses and income, as well as assets and liabilities, into US$ at exchange rates in effect during or at the end of each reporting period. In December 2018, we decided to manage exposure to local currency fluctuation with respect to income tax balances in Colombia. Consequently, we entered into a derivative financial instrument with a local bank in Colombia, for an amount equivalent to US$ 92.1 million, in order to anticipate any currency fluctuation with respect to estimated income taxes to be paid during the first half of 2019.

Through our Brazilian operations, we are exposed to fluctuations in the real against the US$, as our Brazilian revenues and expenses are mostly denominated in reais. In the past, the Brazilian Central Bank has occasionally intervened to control unstable movements in foreign exchange rates. We cannot predict whether the Brazilian Central Bank or the Brazilian government will continue to permit the real to float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. Furthermore, Brazilian law provides that, whenever there is a serious imbalance in Brazil's balance of payments or there are reasons to foresee a serious imbalance, temporary restrictions may be imposed on remittances of foreign capital abroad. We cannot assure you that such measures will not be taken by the Brazilian government in the future. The real has experienced frequent and substantial variations in relation to the US$ and other foreign currencies, which could materially and adversely affect the growth of the Brazilian economy and our business, financial condition and results of operations.

There are inherent risks and uncertainties relating to the exploration and production of oil and natural gas.

Our performance depends on the success of our exploration and production activities and on the existence of the infrastructure that will allow us to take advantage of our oil and gas reserves. Oil and natural gas exploration and production activities are subject to numerous risks beyond our control, including the risk that exploration activities will not identify commercially viable quantities of oil or natural gas. Our decisions to purchase, explore, develop or otherwise exploit prospects or properties will depend in part on the evaluation of seismic and other data obtained through geophysical, geochemical and geological analysis, production data and engineering studies, the results of which are often inconclusive or subject to varying interpretations.

Furthermore, the marketability of any oil and natural gas production from our projects may be affected by numerous factors beyond our control. These factors include, but are not limited to, proximity and capacity of pipelines and other means of transportation, the availability of upgrading and processing facilities, equipment availability and government laws and regulations (including, without limitation, laws and regulations relating to prices, sale restrictions, taxes, governmental stake, allowable production, importing and exporting of oil and natural gas, environmental protection and health and safety). The effect of these factors, individually or jointly, cannot be accurately predicted, but may have a material adverse effect on our business, financial condition and results of operations.

There can be no assurance that our drilling programs will produce oil and natural gas in the quantities or at the costs anticipated, or that our currently producing projects will not cease production, in part or entirely. Drilling programs may become uneconomic as a result of an increase in our operating costs or as a result of a decrease in market prices for oil and natural gas. Our actual operating costs or the actual prices we may receive for our oil and natural gas production may differ materially from current estimates. In addition, even if we are able to continue to produce oil and gas, there can be no assurance that we will have the ability to market our oil and gas production. See “—Our inability to access needed equipment and infrastructure in a timely manner may hinder our access to oil and natural gas markets and generate significant incremental costs or delays in our oil and natural gas production” below.

Our identified potential drilling location inventories are scheduled over many years, making them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling.

Our management team has specifically identified and scheduled certain potential drilling locations as an estimation of our future multi-year drilling



activities on our existing acreage. These identified potential drilling locations, including those without proved undeveloped reserves, represent a significant part of our growth strategy.

Our ability to drill and develop these identified potential drilling locations depends on a number of factors, including oil and natural gas prices, the availability and cost of capital, drilling and production costs, the availability of drilling services and equipment, drilling results, lease expirations, the availability of gathering systems, marketing and transportation constraints, refining capacity, regulatory approvals and other factors. Because of the uncertainty inherent in these factors, there can be no assurance that the numerous potential drilling locations we have identified will ever be drilled or, if they are, that we will be able to produce oil or natural gas from these or any other potential drilling locations.

## Our business requires significant capital investment and maintenance expenses, which we may be unable to finance on satisfactory terms or at all.

Because the oil and natural gas industry is capital intensive, we expect to make substantial capital expenditures in our business and operations for the exploration and production of oil and natural gas reserves. See "Item 4. Information on the Company – B. Business Overview—2019 Strategy and Outlook." We incurred capital expenditures of US$125 million and US$106 million during the years ended December 31, 2018 and 2017, respectively. See "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Factors Affecting our Results of Operations—Discovery and exploitation of reserves."

The actual amount and timing of our future capital expenditures may differ materially from our estimates as a result of, among other things, commodity prices, actual drilling results, the availability of drilling rigs and other equipment and services, and regulatory, technological and competitive developments. In response to changes in commodity prices, we may increase or decrease our actual capital expenditures. We intend to finance our future capital expenditures through cash generated by our operations and potential future financing arrangements. However, our financing needs may require us to alter or increase our capitalization substantially through the issuance of debt or equity securities or the sale of assets.

If our capital requirements vary materially from our current plans, we may require further financing. In addition, we may incur significant financial indebtedness in the future, which may involve restrictions on other financing and operating activities. We may also be unable to obtain financing or financing on terms favorable to us. These changes could cause our cost of doing business to increase, limit our ability to pursue acquisition opportunities, reduce cash flow used for drilling and place us at a competitive disadvantage. A significant reduction in cash flows from operations or the availability of credit could materially adversely affect our ability to achieve our planned growth and operating results.
Oil and gas operations contain a high degree of risk and we may not be fully insured against all risks we face in our business.

Oil and gas exploration and production is speculative and involves a high degree of risk and hazards. In particular, our operations may be disrupted by risks and hazards that are beyond our control and that are common among oil and gas companies, including environmental hazards, blowouts, industrial accidents, occupational safety and health hazards, technical failures, labor disputes, community protests or blockades, unusual or unexpected geological formations, flooding, earthquakes and extended interruptions due to weather conditions, explosions and other accidents.

While we believe that we maintain customary insurance coverage for companies engaged in similar operations, we are not fully insured against all risks in our business. In addition, insurance that we do and plan to carry may contain significant exclusions from and limitations on coverage. We may elect not to obtain certain non-mandatory types of insurance if we believe that the cost of available insurance is excessive relative to the risks presented. The occurrence of a significant event or a series of events against which we are not fully insured and any losses or liabilities arising from uninsured or underinsured events could have a material adverse effect on our business, financial condition or results of operations.

## The development schedule of oil and natural gas projects is subject to cost overruns and delays.

Oil and natural gas projects may experience capital cost increases and overruns due to, among other factors, the unavailability or high cost of drilling rigs and other essential equipment, supplies, personnel and oil field services. The cost to execute projects may not be properly established and remains dependent upon a number of factors, including the completion of detailed cost estimates and final engineering, contracting and procurement costs. Development of projects may be materially adversely affected by one or more of the following factors:

• shortages of equipment, materials and labor;

• fluctuations in the prices of construction materials;

• delays in delivery of equipment and materials;

• labor disputes;

• political events;

• title problems;

• obtaining easements and rights of way;

• blockades or embargoes;

• litigation;

• compliance with governmental laws and regulations, including environmental, health and safety laws and regulations;

• adverse weather conditions;

• unanticipated increases in costs;

• natural disasters;

• accidents;



• transportation;

• unforeseen engineering and drilling complications;

• environmental or geological uncertainties; and

• other unforeseen circumstances.

Any of these events or other unanticipated events could give rise to delays in development and completion of our projects and cost overruns.

For example, in 2017, the drilling and completion cost for the exploratory well Rio Grande Oeste x-1 in our CN-V Block in Argentina was originally estimated at US$4.2 million, but the actual cost was US$5.5 million, mainly due to mechanical issues related to failures with an electric submersible pump, as well as testing of additional formations which had not been budgeted.

Delays in the construction and commissioning of projects or other technical difficulties may result in future projected target dates for production being delayed or further capital expenditures being required. These projects may often require the use of new and advanced technologies, which can be expensive to develop, purchase and implement and may not function as expected. Such uncertainties and operating risks associated with development projects could have a material adverse effect on our business, results of operations or financial condition.

Competition in the oil and natural gas industry is intense, which makes it difficult for us to attract capital, acquire properties and prospects, market oil and natural gas and secure trained personnel.

We compete with the major oil and gas companies engaged in the exploration and production sector, including state-owned exploration and production companies that possess substantially greater financial and other resources than we do for researching and developing exploration and production technologies and access to markets, equipment, labor and capital required to acquire, develop and operate our properties. We also compete for the acquisition of licenses and properties in the countries in which we operate.

Our competitors may be able to pay more for productive oil and natural gas properties and exploratory prospects and to evaluate, bid for and purchase a greater number of properties and prospects than our financial or personnel resources permit. Our competitors may also be able to offer better compensation packages to attract and retain qualified personnel than we are able to offer. In addition, there is substantial competition for capital available for investment in the oil and natural gas industry. As a result of each of the aforementioned, we may not be able to compete successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, attracting and retaining quality personnel or raising additional capital, which could have a material adverse effect on our business, financial condition or results of operations. See “Item 4. Information on the Company—B. Business Overview—Our competition.”

Our estimated oil and gas reserves are based on assumptions that may prove inaccurate.

Our oil and gas reserves estimates in Colombia, Chile, Argentina, Brazil, and Peru as of December 31, 2018 are based on the D&M Reserves Report. Although classified as “proved reserves,” the reserves estimates set forth in the D&M Reserves Reports are based on certain assumptions that may prove inaccurate. DeGolyer and MacNaughton’s primary economic assumptions in estimates included oil and gas sales prices determined according to SEC guidelines, future expenditures and other economic assumptions (including interests, royalties and taxes) as provided by us.

Oil and gas reserves engineering is a subjective process of estimating accumulations of oil and gas that cannot be measured in an exact way, and estimates of other engineers may differ materially from those set out herein. Numerous assumptions and uncertainties are inherent in estimating quantities of proved oil and gas reserves, including projecting future rates of production, timing and amounts of development expenditures and prices of oil and gas, many of which are beyond our control. Results of drilling, testing and production after the date of the estimate may require revisions to be made. For example, if we are unable to sell our oil and gas to customers, this may impact the estimate of our oil and gas reserves. Accordingly, reserves estimates are often materially different from the quantities of oil and gas that are ultimately recovered, and if such recovered quantities are substantially lower than the initial reserves estimates, this could have a material adverse impact on our business, financial condition and results of operations.

Our inability to access needed equipment and infrastructure in a timely manner may hinder our access to oil and natural gas markets and generate significant incremental costs or delays in our oil and natural gas production.

Our ability to market our oil and natural gas production depends substantially on the availability and capacity of processing facilities, oil tankers, transportation facilities (such as pipelines, crude oil unloading stations and trucks) and other necessary infrastructure, which may be owned and operated by third parties. Our failure to obtain such facilities on acceptable terms or on a timely basis could materially harm our business. We may be required to shut down oil and gas wells because access to transportation or processing facilities may be limited or unavailable when needed. If that were to occur, then we would be unable to realize revenue from those wells until arrangements were made to deliver the production to market, which could cause a material adverse effect on our business, financial condition and results of operations. In addition, the shutting down of wells can lead to mechanical problems upon bringing the production back on line, potentially resulting in decreased production and increased remediation costs. The exploitation and sale of oil and natural gas and liquids will also be subject to timely commercial processing and marketing of these products, which depends on the contracting, financing, building and operating of infrastructure by third parties.



In Colombia, producers of crude oil have historically suffered from tanker transportation logistics issues and limited pipeline and storage capacity, which cause delays in delivery and transfer of title of crude oil. Such capacity issues in Colombia may require us to transport crude from our Colombian operations via truck, which may increase the costs of those operations. Road infrastructure is limited in certain areas in which we operate, and certain communities have used and may continue to use road blockages, which can sometimes interfere with our operations in these areas. For example, in 2018, the main delivery point for the Colombian production was Oleoducto de Los Llanos "ODL." During the last week of July 2018, the operation of the Ocensa Pipeline, which receives oil flow from the ODL Pipeline, was disrupted because of a contingency. Although we were able to enable alternative delivery points and transport oil by trucks, avoiding any negative impact in our production during this period, we cannot assure we would be able to do so in the future.

In Chile, we transport the crude oil we produce in the Fell Block by truck to ENAP's processing, storage and selling facilities at the Gregorio Refinery. As of the date of this annual report, ENAP purchases all of the crude oil we produce in Chile. We rely upon the continued good condition, maintenance and accessibility of the roads we use to deliver the crude oil we produce. If the condition of these roads were to deteriorate or if they were to become inaccessible for any period of time, this could delay delivery of crude oil in Chile and materially harm our business.

In the Fell Block, we depend on ENAP-owned gas pipelines to deliver the gas we produce to Methanex, the principal purchaser of the gas we produce. If ENAP's pipelines were unavailable, this could have a materially adverse effect on our ability to deliver and sell our product to Methanex, which could have a material adverse effect on our gas sales. In addition, gas production in some areas in the Tierra del Fuego Blocks and the Tranquilo Block could require us in the future to build a new network of gas pipelines in order for us to be able to deliver our product to market, which could require us to make significant capital investments.

While Brazil has a well-developed network of hydrocarbon pipelines, storage and loading facilities, we may not be able to access these facilities when needed. Pipeline facilities in Brazil are often full and seasonal capacity restrictions may occur, particularly in natural gas pipelines. Our failure to secure transportation or access to pipelines or other facilities once we commence operations in the concessions we were awarded in Brazil on acceptable terms or on a timely basis could materially harm our business.

In Peru, future production in the Morona Block is expected to be transported through the existing North Peruvian Pipeline, which was out of service in 2017 due to technical issues and presented some interruptions to service during 2018. Though the Peruvian government is implementing a program to maintain and modernize the pipeline, future technical issues, other general infrastructure problems or social unrest affecting pipeline operation may adversely affect the recoverability of our future investments, our future production or revenues related to the Morona Block.
In addition, as the Morona Block is located in a remote area of the tropical rainforest, the development of the project involves significant infrastructure to be built, including processing facilities, storages tanks and a 37 kilometers-long flexible pipeline which is required to start production. In addition, the full development of the project would require a 97 kilometers-long pipeline from the site to the North Peruvian Pipeline. Also, as there are no roads available in the surrounding area, logistics will be performed by helicopters or barges. These issues may lead us to incur significant costs or investments that may not be recoverable through our commercial activities in the Morona Block.

In Argentina, we deliver a portion of our oil production and all of our gas production via existing pipeline infrastructure controlled by third parties. While both the oil and gas pipeline systems in Argentina are well-developed and have operated reliably in the past, we cannot guarantee this will continue in the future. In addition, as Argentina's production grows, pipeline capacity may become insufficient. We also deliver a portion of our crude production at well-head. This volume is lifted from our loading facilities by third-party operated trucks contracted by our clients. The roads around our fields are in good condition but changes in those conditions could adversely affect our operations. Our failure to secure transportation or access to pipelines or other facilities on acceptable terms or on a timely basis could materially harm our business.

Through our Brazilian operations, we face operational risks relating to offshore drilling.

Our operations in the BCAM-40 Concession in Brazil may include shallow-offshore drilling activity in one area in the Camamu-Almada Basin, which we expect will continue to be operated by Petrobras.

Offshore operations are subject to a variety of operating risks and laws and regulations, including among other things, with respect to environmental, health and safety matters, specific to the marine environment, such as capsizing, collisions and damage or loss from hurricanes or other adverse weather conditions. These conditions can cause substantial damage to facilities and interrupt production. As a result, we could incur substantial liabilities, compliance costs, fines or penalties that could reduce or eliminate the funds available for exploration, development or leasehold acquisitions, or result in loss of equipment and properties. For example, the Manati Field has been subject to administrative infraction notices, which have resulted in fines against Petrobras in an aggregate amount of approximately US$12 million, all of which are pending a final decision of the Brazilian Institute for the Environment and Natural Renewable Resources (Instituto Brasileiro do Meio-Ambiente e dos Recursos Naturais Renováveis). Although the administrative fines were filed against Petrobras, as a party to the concession agreement governing the Manati Field, we may be liable up to our participation interest of 10%.

Additionally, offshore drilling generally requires more time and more



advanced drilling technologies, involving a higher-risk of technological failure and usually higher drilling costs. Offshore projects often lack proximity to existing oilfield service infrastructure, necessitating significant capital investment in flow line infrastructure before we can market the associated oil or gas of a commercial discovery, increasing both the financial and operational risk involved with these operations. Because of the lack and high cost of infrastructure, some offshore reserve discoveries may never be produced economically.

Further, because we are not the operator of our offshore fields, all of these risks may be heightened since they are outside of our control. We have a 10% interest in the Manati Field which limits our operating flexibility in such offshore fields. See “—We are not, and may not be in the future, the sole owner or operator of all of our licensed areas and do not, and may not in the future, hold all of the working interests in certain of our licensed areas. Therefore, we may not be able to control the timing of exploration or development efforts, associated costs, or the rate of production of any non-operated and, to an extent, any non-wholly-owned, assets.”

Our pending acquisition of the Espejo and Perico blocks in Ecuador is subject to regulatory approvals.

In March 2019, GeoPark, in consortium with Frontera (50% GeoPark, 50% Frontera) was awarded the Espejo and Perico blocks in the form of production sharing contracts in the Intracampos Bid Round carried out on March 12, 2019 in Quito, Ecuador. The closing of the acquisition is subject to the occurrence of certain conditions, including obtaining other governmental approvals. Failure to obtain such approvals may result in the termination of the agreement. We expect the transaction to close in the second quarter of 2019 but we cannot guarantee that the regulatory approvals will be obtained by that time or that the acquisition will be completed on this timeline.

Following the eventual completion of this acquisition, conducting operations in Ecuador, a new jurisdiction for us, will subject us to risks that are inherent for foreign companies operating in Ecuador, including challenges posed by different laws and customs; lack of familiarity and burdens of complying with such foreign laws, legal standards, regulatory requirements, tariffs and other barriers; unexpected changes in regulatory requirements, taxes, trade laws, tariffs, export quotas, custom duties or other trade restrictions; potential difficulties in collecting accounts receivable; difficulties in managing and staffing operations; varying expectations as to employee standards; potentially adverse tax consequences, including possible restrictions on the repatriation of earnings. Moreover, operations in Ecuador could be interrupted and negatively affected by economic changes, geopolitical regional conflicts, terrorist activity, political unrest, civil strife, acts of war and other economic or political uncertainties. All of these risks could result in increased costs which could have a material adverse effect on our financial condition, results of operations and cash flows.
We may suffer delays or incremental costs due to difficulties in negotiations with landowners and local communities, including native communities, where our reserves are located.

Access to the sites where we operate requires agreements (including, for example, assessments, rights of way and access authorizations) with landowners and local communities. If we are unable to negotiate agreements with landowners, we may have to go to court to obtain access to the sites of our operations, which may delay the progress of our operations at such sites. In Chile and in Argentina, for example, we have negotiated the necessary agreements for many of our current operations in the Magallanes Basin, in Neuquén and in Mendoza (when we had the operatorship of the CN-V Block), respectively. In Brazil, in the event that social unrest continues or intensifies, this may lead to delays or damage relating to our ability to operate the assets we have acquired or may acquire in our Brazil Acquisitions.

In Colombia, although we have agreements with many landowners and are in negotiations with others, we expect our costs to increase following current and future negotiations regarding access to our blocks, as the economic expectations of landowners have generally increased, which may delay access to existing or future sites. In addition, the expectations and demands of local communities on oil and gas companies operating in Colombia may also increase. As a result, local communities have demanded that oil and gas companies invest in remediating and improving public access roads, compensate them for any damages related to use of such roads and, more generally, invest in infrastructure that was previously paid for with public funds. Due to these circumstances, oil and gas companies in Colombia, including us, are now dealing with increasing difficulties resulting from instances of social unrest, temporary road blockages and conflicts with landowners.

There can be no assurance that disputes with landowners and local communities will not delay our operations or that any agreements we reach with such landowners and local communities in the future will not require us to incur additional costs, thereby materially adversely affecting our business, financial condition and results of operations. Local communities may also protest or take actions that restrict or cause their elected government to restrict our access to the sites of our operations, which may have a material adverse effect on our operations at such sites.

In Peru, the Morona Block is located in land inhabited by native communities. Though we have already signed certain agreements with native communities authorizing the execution of the environmental impact assessment for the Morona Project, which the environmental authority is currently analyzing, similar projects in the Peruvian rainforest have faced significant social conflicts and work delays due to community claims. Social conflicts or community claims could adversely affect the recoverability of our future investments, our future production and revenues related to the Morona Block.



Under the terms of some of our various CEOPs, E&P Contracts and concession agreements, we are obligated to drill wells, declare any discoveries and file periodic reports in order to retain our rights and establish development areas. Failure to meet these obligations may result in the loss of our interests in the undeveloped parts of our blocks or concession areas.

In order to protect our exploration and production rights in our license areas, we must meet various drilling and declaration requirements. In general, unless we make and declare discoveries within certain time periods specified in our various special operation contracts (Contratos Especiales de Operación para la Exploración y Explotación de Yacimientos de Hidrocarburo; hereinafter "CEOP"), E&P Contracts and concession agreements, our interests in the undeveloped parts of our license areas may lapse. Should the prospects we have identified under these contracts and agreements yield discoveries, we may face delays in drilling these prospects or be required to relinquish these prospects. The costs to maintain or operate the CEOPs, E&P Contracts and concession agreements over such areas may fluctuate and may increase significantly, and we may not be able to meet our commitments under such contracts and agreements on commercially reasonable terms or at all, which may force us to forfeit our interests in such areas. For example, in 2016, after fulfilling the committed exploratory commitments, five exploratory blocks were relinquished to the ANP. See "Item 4. Information on the Company—B. Business Overview—Our operations—Operations in Brazil."

In Peru, the rights to explore and produce hydrocarbons are granted through a license contract signed with Perupetro. The scope and schedule of such development will depend on us and Perpetro. The license contract could be terminated by Perupetro if the development obligations included in such agreement are not fulfilled. In addition, there is also an exploratory commitment consisting of the drilling of one exploratory well every two and a half years. Failure to fulfill the exploratory commitment will lead to acreage relinquishment materially affecting the project. Moreover, we have entered into a Joint Investment Agreement with Perpetro by which, subject to the economic and technical feasibility of the Morona Project, we are obliged to bear 100% of capital cost required to carry out long test to existing well Situche Central 3X, and if we decide to continue with the project after that, to the existing well Situche Central 2X. In addition, we are required to cover any capital or operational expenditures associated with the project until December 31, 2020. We expect these expenditures to be substantially reimbursed by Perpetro from revenues associated with future sales. Failure to fulfill such obligations will result in the loss of our participating interest in the License Contract of the Morona Block, and subject us to possible damage claims from Perpetro.

For additional details regarding the status of our operations with respect to our various special contracts and concession agreements, see “Item 4. Information on the Company—B. Business Overview—Our operations.”
A significant amount of our reserves or production have been derived from our operations in certain blocks, including the Llanos 34 Block in Colombia, the Fell Block in Chile, the BCAM-40 Concession in Brazil, the Aguada Baguales Block in Argentina and the Morona Block in Peru.

For the year ended December 31, 2018, the Llanos 34 Block contained 67% of our net proved reserves and generated 76% of our production, the Fell Block contained 6% of our net proved reserves and generated 8% of our total production, the BCAM-40 Concession contained 3% of our net proved reserves and generated 8% of our production, the Aguada Baguales Block contained 3% of our proved reserves and generated 3% of our total production and the Morona Block contained 17% of our net proved reserves. While our continuing expansion with new exploratory blocks incorporated in our portfolio mean that the above mentioned blocks may be expected to be a less significant component of our overall business, we cannot be sure that we will be able to continue diversifying our reserves and production. Resulting from these, any government intervention, impairment or disruption of our production due to factors outside of our control or any other material adverse event in our operations in such blocks would have a material adverse effect on our business, financial condition and results of operations.

Our contracts in obtaining rights to explore and develop oil and natural gas reserves are subject to contractual expiration dates and operating conditions, and our CEOPs, E&P Contracts and concession agreements are subject to early termination in certain circumstances.

Under certain CEOPs, E&P Contracts and concession agreements to which we are or may in the future become parties, we are or may become subject to guarantees to perform our commitments and/or to make payment for other obligations, and we may not be able to obtain financing for all such obligations as they arise. If such obligations are not complied with when due, in addition to any other remedies that may be available to other parties, this could result in cancelation of our CEOPs, E&P Contracts and concession agreements or dilution or forfeiture of interests held by us. As of December 31, 2018, the aggregate outstanding amount of this potential liability for guarantees was US$38.9 million, mainly related to capital commitments in Isla Norte, Campanario and Flamenco Blocks in Chile, rounds 11, 12 and 13 concessions in Brazil, the Morona Block in Peru and the VIM-3, and Llanos 34 Blocks in Colombia. See "Item 4. Information on the Company—B. Business Overview—Our operations" and Note 32.2 to our Consolidated Financial Statements.

Additionally, certain of the CEOPs, E&P Contracts and concession agreements to which we are or may in the future become a party are subject to set expiration dates. Although we may want to extend some of these contracts beyond their original expiration dates, there is no assurance that we can do so on terms that are acceptable to us or at all, although some CEOPs contain provisions enabling exploration extensions.



In Colombia, our E&P Contracts may be subject to early termination for a breach by the parties, a default declaration, application of any of the contracts' unilateral termination clauses or pursuant to termination clauses mandated by Colombian law. Anticipated termination declared by the ANH results in the immediate enforcement of monetary guaranties against us and may result in an action for damages by the ANH and/or a restriction on our ability to engage in contracts with the Colombian government during a certain period of time. See "Item 4. Information on the Company—B. Business Overview—Significant Agreements—Colombia—E&P Contracts."

In Chile, our CEOPs provide for early termination by Chile in certain circumstances, depending upon the phase of the CEO. For example, pursuant to the Fell Block CEO, Chile has the right to terminate the CEO under certain circumstances if we fail to perform. If the Fell Block CEO is terminated in the exploitation phase, we will have to transfer to Chile, free of charge, any productive wells and related facilities, provided that such transfer does not interfere with our abandonment obligations and excluding certain pipelines and other assets. See "Item 4. Information on the Company—B. Business Overview—Significant Agreements—Chile—CEOPs—Fell Block CEO." If the CEO is terminated early due to a breach of our obligations, we may not be entitled to compensation. Our CEOPs for the Tierra del Fuego Blocks, which are in the exploration phase, may be subject to early termination during this phase under certain circumstances, including if we fail to perform under the terms of the CEOPs, voluntarily relinquish all areas under the CEOPs or if we cease to operate in the CEO area or declare bankruptcy. If the Tierra del Fuego Block CEOPs are terminated within the exploration phase, we are released from all obligations under the CEOPs, except for obligations regarding the abandonment of fields, if any. See "Item 4. Information on the Company—B. Business Overview—Significant Agreements—Chile—CEOPs." There can be no assurance that the early termination of any of our CEOPs would not have a material adverse effect on us. In addition, according to the Chilean Constitution, Chile is entitled to expropriate our rights in our CEOPs for reasons of public interest. Although Chile would be required to indemnify us for such expropriation, there can be no assurance that any such indemnification will be paid in a timely manner or in an amount sufficient to cover the harm to our business caused by such expropriation.

In Brazil, concession agreements in the production phase generally may be renewed at the ANP's discretion for an additional period, provided that a renewal request is made at least 12 months prior to the termination of the concession agreement and there has not been a breach of the terms of the concession agreement. We expect that all our concession agreements will provide for early termination in the event of: (i) government expropriation for reasons of public interest; (ii) revocation of the concession pursuant to the terms of the concession agreement; or (iii) failure by us or our partners to fulfill all of our respective obligations under the concession agreement (subject to a cure period). Administrative or monetary sanctions may also be applicable, as determined by the ANP, which shall be imposed based on applicable law and regulations. In the event of early termination of a concession agreement, the compensation to which we are entitled may not be sufficient to compensate us for the full value of our assets. Moreover, in the event of early termination of any concession agreement due to failure to fulfill obligations thereunder, we may be subject to fines and/or other penalties.

In Peru, License Contracts for hydrocarbon exploitation are in force and will remain in effect for 30 years. This term is non-renewable. With regard to the Morona Block, approximately one-third of the contract term has already elapsed, and twenty years remain. Nevertheless, since May 14, 2013, the License Contract related to the Morona Block is under force majeure. During a force majeure period contract terms are suspended (including the term time) as long as the party to the contract is fulfilling certain obligations related to obtaining environmental permits, as is currently the case with the Morona Block. The term of the agreement will be extended by the same amount of time it has been suspended by a force majeure event. The concession year expiration is related to the approval of the environmental impact assessment for the project's development. The expiration of the License Contract will occur twenty years after the approval of the environmental impact assessment. The License Contract is also subject to early termination in case of our breach of contractual obligations. In such an event, all the existing facilities and wells located in the block will be transferred, without charge, to Perupetro, and we will have to carry out abandonment plans for remediation and restoration of any polluted area in the block and for de-commission the facilities that are no longer required for the block's operations.

In Argentina, hydrocarbon exploration permits and exploitation concessions are subject to termination for: (a) failure to pay any annual license fees within three months after they are due; (b) failure to pay royalties within three months after they are due; (c) material and unjustified failure to comply with the specified obligations in respect to productivity, conservation, investments, works or special benefits; (d) repeated infringement of the obligations to submit demandable information, to facilitate inspections by the competent authority or to employ the proper techniques for the execution of the works; (e) failure to request an exploitation concession after a commercial discovery or to submit a development program after obtaining an exploitation concession; (f) the bankruptcy of the holder declared by a court; (g) the death or liquidation of the holder; or, (h) failure to comply with the obligation to transport hydrocarbons for third parties under open access conditions or repeated infringement of the tariff regime approved for such transport. Before declaring the termination under any of the grounds provided under items (a), (b), (c), (d), (e), and (h), notice shall be served, requiring the holder to remedy any such infringement. Upon expiration, relinquishment or termination of any permit or concession, the holder of such permit or concession shall surrender to the government the acreage together with all of the improvements, facilities, wells and other equipment that may have been used in the performance of the activities.

Early termination or nonrenewal of any CEOP, E&P Contract or concession agreement could have a material adverse effect on our business, financial situation or results of operations.



We sell almost all of our natural gas in Chile to a single customer, who has in the past temporarily idled its principal facility.

For the year ended December 31, 2018, almost all of our natural gas sales in Chile were made to Methanex under a long-term contract, the Methanex Gas Supply Agreement, which expires on December 31, 2026. Under the agreement, Methanex committed to purchase up to 400,000 SCM/d of gas produced by us. Due to the decline in our gas production, the commitment was reduced to 315,000 SCM/d in 2018, according to the initial terms of our contract. The commitment has remained at 315,000 SCM/d for 2019. We also hold an option to deliver up to 15% above this volume. Sales to Methanex represented 3% of our consolidated revenues for the year ended December 31, 2018. Methanex also buys gas from ENAP and a consortium that Methanex has formed with ENAP. If Methanex were to decrease or cease its purchase of gas from us, this would have a material adverse effect on our revenues derived from the sale of gas.

Methanex has two methanol producing facilities at its Cabo Negro production facility, near the city of Punta Arenas in southern Chile. Methanex has relied on local suppliers of natural gas, including ENAP, for its operations. We alone cannot supply Methanex with all the natural gas it requires for its operations. In 2018, Argentina approved export permits of natural gas to Chile, including deliveries to Methanex.

In the past, the Methanex plant was idled due to an anticipated insufficient supply of natural gas. The supply of natural gas decreased during the winter months of 2015 due to the increase in seasonal gas demand from the city of Punta Arenas, to which gas producers, including us, gave priority by delivering gas to the city through Methanex which re-sold our gas to ENAP. In May 2017, the Methanex plant shut down because of a technical failure which affected our natural gas production and sales for 20 days. See “Item 4. Information on the Company—B. Business Overview—Marketing and delivery commitments—Chile.”

However, we cannot be sure that Methanex will continue to purchase the gas from us, including the above committed levels, or that its efforts to reduce the risk of future shut-downs will be successful, which could have a material adverse effect on our gas revenues. Additionally, we cannot be sure that Methanex will have sufficient supplies of gas to operate its plant and continue to purchase our gas production or that methanol prices would be sufficient to cover the operating costs. We cannot be sure that we would be able to sell our gas production to other parties or on similar terms, which could have a material adverse effect on our business, financial condition and results of operations.

We are not, and may not be in the future, the sole owner or operator of all of our licensed areas and do not, and may not in the future, hold all of the working interests in certain of our licensed areas. Therefore, we may not be able to control the timing of exploration or development efforts, associated costs, or the rate of production of any non-operated and, to an extent, any non-wholly-owned, assets.

As of December 31, 2018, we are not the operator of 27% or sole owner of 31% of the blocks included in our portfolio. See “Item 4. Information on the Company—B. Business Overview—Operations in Colombia, Operations in Chile, Operations in Brazil, Operations in Peru and Operations in Argentina.”

In addition, the terms of the joint operation agreements or association agreements governing our other partners’ interests in almost all of the blocks that are not wholly-owned or operated by us require that certain actions be approved by supermajority vote. The terms of our other current or future license or venture agreements may require at least the majority of working interests to approve certain actions. As a result, we may have limited ability to exercise influence over operations or prospects in the blocks operated by our partners, or in blocks that are not wholly-owned or operated by us. A breach of contractual obligations by our partners who are the operators of such blocks could eventually affect our rights in exploration and production contracts in some of our blocks in Colombia, Argentina and Brazil. Our dependence on our partners could prevent us from realizing our target returns for those discoveries or prospects.

Moreover, as we are not the sole owner or operator of all of our properties, we may not be able to control the timing of exploration or development activities or the amount of capital expenditures and may therefore not be able to carry out our key business strategies of minimizing the cycle time between discovery and initial production at such properties. The success and timing of exploration and development activities operated by our partners will depend on a number of factors that will be largely outside of our control, including:

• the timing and amount of capital expenditures;

• the operator’s expertise and financial resources;

• approval of other block partners in drilling wells;

• the scheduling, pre-design, planning, design and approvals of activities and processes;

• selection of technology; and

• the rate of production of reserves, if any.

This limited ability to exercise control over the operations on some of our license areas may cause a material adverse effect on our financial condition and results of operations.

Acquisitions that we have completed and any future acquisitions, strategic investments, partnerships or alliances could be difficult to integrate and/or identify, could divert the attention of key management personnel, disrupt our business, dilute stockholder value and adversely affect our financial results, including impairment of goodwill and other intangible assets.

One of our principal business strategies includes acquisitions of properties,



prospects, reserves and leaseholds and other strategic transactions, including in jurisdictions in which we do not currently operate. The successful acquisition and integration of producing properties requires an assessment of several factors, including:

• recoverable reserves;

• future oil and natural gas prices;

• development and operating costs; and

• potential environmental and other liabilities.

The accuracy of these assessments is inherently uncertain. In connection with these assessments, we perform a review of the subject properties that we believe to be generally consistent with industry practices. Our review and the review of advisors and independent reserves engineers will not reveal all existing or potential problems, nor will it permit us or them to become sufficiently familiar with the properties to fully assess their deficiencies and potential recoverable reserves. Inspections may not always be performed on every well, and environmental conditions are not necessarily observable even when an inspection is undertaken. We, advisors or independent reserves engineers may apply different assumptions when assessing the same field. Even when problems are identified, the seller may be unwilling or unable to provide effective contractual protection against all or part of the problems. We often are not entitled to contractual indemnification for environmental liabilities and acquire properties on an “as is” basis. Even in those circumstances in which we have contractual indemnification rights for pre-closing liabilities, it remains possible that the seller will not be able to fulfill its contractual obligations. There can be no assurance that problems related to the assets or management of the companies and operations we have acquired, or operations we may acquire or add to our portfolio in the future, will not arise in future, and these problems could have a material adverse effect on our business, financial condition and results of operations.

Significant acquisitions and other strategic transactions may involve other risks, including:

• diversion of our management’s attention to evaluating, negotiating and integrating significant acquisitions and strategic transactions;

• challenge and cost of integrating acquired operations, information management and other technology systems and business cultures with ours while carrying on our ongoing business;

• contingencies and liabilities that could not be or were not identified during the due diligence process, including with respect to possible deficiencies in the internal controls of the acquired operations; and

• challenge of attracting and retaining personnel associated with acquired operations.

It is also possible that we may not identify suitable acquisition targets or strategic investment, partnership or alliance candidates. Our inability to identify suitable acquisition targets, strategic investments, partners or alliances, or our inability to complete such transactions, may negatively affect our competitiveness and growth opportunities. Moreover, if we fail to properly evaluate acquisitions, alliances or investments, we may not achieve the anticipated benefits of any such transaction, and we may incur costs in excess of what we anticipate.

Future acquisitions financed with our own cash could deplete the cash and working capital available to adequately fund our operations. We may also finance future transactions through debt financing, the issuance of our equity securities, existing cash, cash equivalents or investments, or a combination of the foregoing. Acquisitions financed with the issuance of our equity securities could be dilutive, which could affect the market price of our stock. Acquisitions financed with debt could require us to dedicate a substantial portion of our cash flow to principal and interest payments and could subject us to restrictive covenants.

## The PN-T-597 Concession Agreement in Brazil may not close.

In Brazil, GeoPark Brasil is a party to a class action filed by the Federal Prosecutor's Office regarding a concession agreement of exploratory Block PN-T-597, which the ANP initially awarded GeoPark Brasil in the 12th oil and gas bidding round held in November 2013. The Brazilian Federal Court issued an injunction against the ANP and GeoPark Brasil in December 2013 that prohibited GeoPark Brasil's execution of the concession agreement until the ANP conducted studies on whether drilling for unconventional resources would contaminate the dams and aquifers in the region. On July 17, 2015, GeoPark Brasil, at the instruction of the ANP, signed the concession agreement, which included a clause prohibiting GeoPark Brasil from conducting unconventional exploration activity in the area. Despite the clause containing the prohibition, the judge in the case concluded that the concession agreement should not be executed. Thus, GeoPark Brasil requested that the ANP comply with the decision and annul the concession agreement, which the ANP's Board did on October 9, 2015. The annulment reverted the status of all parties to the status quo ante, which maintains GeoPark Brasil's right to the block.

There is no assurance that we will be able to enter into a concession agreement in the PN-T-597 Block that would be favorable to our exploration goals. See "Item 8—Financial Information—A. Consolidated statements and other financial information—Legal proceedings."

The present value of future net revenues from our proved reserves will not necessarily be the same as the current market value of our estimated oil and natural gas reserves.

You should not assume that the present value of future net revenues from our proved reserves is the current market value of our estimated oil and natural gas reserves. For the year ended December 31, 2018, we have based the estimated discounted future net revenues from our proved reserves on the 12-month unweighted arithmetic average of the first-day-of-the-month price for the preceding 12 months. Actual future net revenues from our oil and natural gas properties will be affected by factors such as:



• actual prices we receive for oil and natural gas;

• actual cost of development and production expenditures;

• the amount and timing of actual production; and

• changes in governmental regulations, taxation or the taxation invariability provisions in our CEOPs.

The timing of both our production and our incurrence of expenses in connection with the development and production of oil and natural gas properties will affect the timing and amount of actual future net revenues from proved reserves, and thus their actual value. In addition, the 10% discount factor we use when calculating discounted future net revenues may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and natural gas industry in general.

The development of our proved undeveloped reserves may take longer and may require higher levels of capital expenditures than we currently anticipate. Therefore, our proved undeveloped reserves ultimately may not be developed or produced.

As of December 31, 2018, 38% of our net proved reserves are developed. Development of our undeveloped reserves may take longer and require higher levels of capital expenditures than we currently anticipate. Additionally, delays in the development of our reserves or increases in costs to drill and develop such reserves will reduce the standardized measure value of our estimated proved undeveloped reserves and future net revenues estimated for such reserves, and may result in some projects becoming uneconomic, causing the quantities associated with these uneconomic projects to no longer be classified as reserves. This was due to the uneconomic status of the reserves, given the proximity to the end of the concessions for these blocks, which does not allow for future capital investment in the blocks. There can be no assurance that we will not experience similar delays or increases in costs to drill and develop our reserves in the future, which could result in further reclassifications of our reserves.

We are exposed to the credit risks of our customers and any material nonpayment or nonperformance by our key customers could adversely affect our cash flow and results of operations.

Our customers may experience financial problems that could have a significant negative effect on their creditworthiness. Severe financial problems encountered by our customers could limit our ability to collect amounts owed to us, or to enforce the performance of obligations owed to us under contractual arrangements.

The combination of declining cash flows as a result of declines in commodity prices, a reduction in borrowing basis under reserves-based credit facilities and the lack of availability of debt or equity financing may result in a significant reduction of our customers' liquidity and limit their ability to make payments or perform on their obligations to us. Furthermore, some of our customers may be highly leveraged, and, in any event, are subject to their own operating expenses. Therefore, the risk we face in doing business with these customers may increase. Other customers may also be subject to regulatory changes, which could increase the risk of defaulting on their obligations to us. Financial problems experienced by our customers could result in the impairment of our assets, a decrease in our operating cash flows and may also reduce or curtail our customers' future use of our products and services, which may have an adverse effect on our revenues and may lead to a reduction in reserves.

We may not have the capital to develop our unconventional oil and gas resources.

We have identified opportunities for analyzing the potential of unconventional oil and gas resources in some of our blocks and concessions. Our ability to develop this potential depends on a number of factors, including the availability of capital, seasonal conditions, regulatory approvals, negotiation of agreements with third parties, commodity prices, costs, access to and availability of equipment, services and personnel and drilling results. In addition, as we have no previous experience in drilling and exploiting unconventional oil and gas resources, the drilling and exploitation of such unconventional oil and gas resources depends on our ability to acquire the necessary technology, to hire personnel and other support needed for extraction or to obtain financing and venture partners to develop such activities. Because of these uncertainties, we cannot give any assurance as to the timing of these activities, or that they will ultimately result in the realization of proved reserves or meet our expectations for success.

Our operations are subject to operating hazards, including extreme weather events, which could expose us to potentially significant losses.

Our operations are subject to potential operating hazards, extreme weather conditions and risks inherent to drilling activities, seismic registration, exploration, production, development and transportation and storage of crude oil, such as explosions, fires, car and truck accidents, floods, labor disputes, social unrest, community protests or blockades, guerilla attacks, security breaches, pipeline ruptures and spills and mechanical failure of equipment at our or third-party facilities. Any of these events could have a material adverse effect on our exploration and production operations or disrupt transportation or other process-related services provided by our third-party contractors.

We are highly dependent on certain members of our management and technical team, including our geologists and geophysicists, and on our ability to hire and retain new qualified personnel.

The ability, expertise, judgment and discretion of our management and our technical and engineering teams are key in discovering and developing oil and natural gas resources. Our performance and success are dependent to a large extent upon key members of our management and exploration team, and their



loss or departure would be detrimental to our future success. In addition, our ability to manage our anticipated growth depends on our ability to recruit and retain qualified personnel. Our ability to retain our employees is influenced by the economic environment and the remote locations of our exploration blocks, which may enhance competition for human resources where we conduct our activities, thereby increasing our turnover rate. There is strong competition in our industry to hire employees in operational, technical and other areas, and the supply of qualified employees is limited in the regions where we operate and throughout Latin America generally. The loss of any of our key management or other key employees of our technical team or our inability to hire and retain new qualified personnel could have a material adverse effect on us.

We and our operations are subject to numerous environmental, health and safety laws and regulations which may result in material liabilities and costs.

We and our operations are subject to various international, foreign, federal, state and local environmental, health and safety laws and regulations governing, among other things, the emission and discharge of pollutants into the ground, air or water; the generation, storage, handling, use, transportation and disposal of regulated materials; and human health and safety. Our operations are also subject to certain environmental risks that are inherent in the oil and gas industry and which may arise unexpectedly and result in material adverse effects on our business, financial condition and results of operations. Breach of environmental laws could result in environmental administrative investigations and/or lead to the termination of our concessions and contracts. Other potential consequences include fines and/or criminal or civil environmental actions. For instance, non-governmental organizations seeking to preserve the environment may bring actions against us or other oil and gas companies in order to, among other things, halt our activities in any of the countries in which we operate or require us to pay fines. Additionally, in Colombia, recent rulings have provided that environmental licenses are administrative acts subject to class actions that could eventually result in their cancellation, with potential adverse impacts on our E&P Contracts.

We have not been and may not be at all times in complete compliance with environmental permits that we are required to obtain for our operations and the environmental and health and safety laws and regulations to which we are subject. If we fail to comply with such requirements, we could be fined or otherwise sanctioned by regulators, including through the revocation of our permits or the suspension or termination of our operations. If we fail to obtain, maintain or renew permits in a timely manner or at all, our operations could be adversely affected, impeded, or terminated, which could have a material adverse effect on our business, financial condition or results of operations. Some environmental licenses related to operation of the Manati Field production system and natural gas pipeline have expired. However, the operator submitted in a timely manner a request for renewal of those licenses and as such this operation is not in default as long as the regulator does not state its final position on the renewal.
We have contracted with and intend to continue to hire third parties to perform services related to our operations. We could be held liable for some or all environmental, health and safety costs and liabilities arising out of our actions and omissions as well as those of our block partners, third-party contractors, predecessors or other operators. To the extent we do not address these costs and liabilities or if we do not otherwise satisfy our obligations, our operations could be suspended, terminated or otherwise adversely affected. There is a risk that we may contract with third parties with unsatisfactory environmental, health and safety records or that our contractors may be unwilling or unable to cover any losses associated with their acts and omissions.

Releases of regulated substances may occur and can be significant. Under certain environmental laws and regulations applicable to us in the countries in which we operate, we could be held responsible for all of the costs relating to any contamination at our past and current facilities and at any third-party waste disposal sites used by us or on our behalf. Pollution resulting from waste disposal, emissions and other operational practices might require us to remediate contamination, or retrofit facilities, at substantial cost. We also could be held liable for any and all consequences arising out of human exposure to such substances or for other damage resulting from the release of hazardous substances to the environment, property or to natural resources, or affecting endangered species or sensitive environmental areas. We are currently required to, and in the future may need to, plug and abandon sites in certain blocks in each of the countries in which we operate, which could result in substantial costs.

In addition, we expect continued and increasing attention to climate change issues. Various countries and regions have agreed to regulate emissions of greenhouse gases including methane (a primary component of natural gas) and carbon dioxide (a byproduct of oil and natural gas combustion). The regulation of greenhouse gases and the physical impacts of climate change in the areas in which we, our customers and the end-users of our products operate could adversely impact our operations and the demand for our products.

In Peru, the beginning of the construction and development phase of the Morona Block is subject to the approval of an environmental impact assessment by the Peruvian environmental authority. If such environmental impact assessment is not approved during the first half of 2019, we will not be able to transport all the goods and materials required for the development of the project during the fluvial transportation window of the Morona River in 2019 and the construction stage of the project will be negatively impacted. If this is the case, the beginning of the production stage of the Morona Project could also be impacted.

Environmental, health and safety laws and regulations are complex and change frequently, and our costs of complying with such laws and regulations may adversely affect our results of operations and financial condition. See “Item



4. Information on the Company—B. Business Overview—Health, safety and environmental matters” and “Item 4. Information on the Company—B. Business Overview—Industry and regulatory framework.”

Legislation and regulatory initiatives relating to hydraulic fracturing and other drilling activities for unconventional oil and gas resources could increase the future costs of doing business, cause delays or impede our plans, and materially adversely affect our operations.

Hydraulic fracturing of unconventional oil and gas resources is a process that involves injecting water, sand, and small volumes of chemicals into the wellbore to fracture the hydrocarbon-bearing rock thousands of feet below the surface to facilitate a higher flow of hydrocarbons into the wellbore. We are contemplating such use of hydraulic fracturing in the production of oil and natural gas from certain reservoirs, especially shale formations. We currently are not aware of any proposals in Colombia, Chile, Brazil, Argentina or Peru to regulate hydraulic fracturing beyond the regulations already in place. However, various initiatives in other countries with substantial shale gas resources have been or may be proposed or implemented to, among other things, regulate hydraulic fracturing practices, limit water withdrawals and water use, require disclosure of fracturing fluid constituents, restrict which additives may be used, or implement temporary or permanent bans on hydraulic fracturing. If any of the countries in which we operate adopts similar laws or regulations, which is something we cannot predict right now, such adoption could significantly increase the cost of, impede or cause delays in the implementation of any plans to use hydraulic fracturing for unconventional oil and gas resources.

Our indebtedness and other commercial obligations could adversely affect our financial health and our ability to raise additional capital and prevent us from fulfilling our obligations under our existing agreements and borrowing of additional funds.

As of December 31, 2018, we had US$447 million of total indebtedness outstanding on a consolidated basis, consisting primarily of our US$425.0 million Notes due 2024, which we issued in September 2017. As of December 31, 2018, our annual debt service obligation was US$27.7 million, see "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Indebtedness."

## Our indebtedness could:

• limit our capacity to satisfy our obligations with respect to our indebtedness, and any failure to comply with the obligations of any of our debt instruments, including restrictive covenants and borrowing conditions, could result in an event of default under the agreements governing our indebtedness;

• require us to dedicate a substantial portion of our cash flow from operations to the payments on our indebtedness, thereby reducing the availability of our cash flow to fund acquisitions, working capital, capital expenditures and other general corporate purposes;

• place us at a competitive disadvantage compared to certain of our competitors that have less debt;

• limit our ability to borrow additional funds;

• in the case of our secured indebtedness, lose assets securing such indebtedness upon the exercise of security interests in connection with a default;

• make us more vulnerable to downturns in our business or the economy; and

• limit our flexibility in planning for, or reacting to, changes in our operations or business and the industry in which we operate.

The indenture governing our Notes due 2024 includes covenants restricting dividend payments. For a description, see “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Indebtedness—Notes due 2024.”

As a result of these restrictive covenants, we are limited in the manner in which we conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. We have in the past been unable to meet incurrence tests under the indenture governing our prior notes, which limited our ability to incur indebtedness. Failure to comply with the restrictive covenants included in our Notes due 2024 would not trigger an event of default.

Similar restrictions could apply to us and our subsidiaries when we refinance or enter into new debt agreements which could intensify the risks described above.

Our business could be negatively impacted by security threats, including cybersecurity threats as well as other disasters, and related disruptions.

As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, have also increased in the world. Computer and telecommunications systems are used to conduct our exploration, development and production activities and have become an integral part of our business. Our business processes depend on the availability, capacity, reliability and security of our information technology infrastructure and our ability to expand and continually update this infrastructure in response to our changing needs. It is critical to our business that our facilities and infrastructure remain secure. Although we have implemented internal control procedures to assure the security of our data, we cannot guarantee that these measures will be sufficient for this purpose. Cyber-attacks could compromise our computers and telecommunications systems and result in disruptions to our business operation necessary to deliver our production to market or the loss of our data.

Although we have extended our security policy to the main systems of



the Company and implemented strategies to mitigate the impact from cybersecurity threats, reinforcing the defenses in case of denial of service and increasing the monitoring of suspicious activities, our technologies, systems, networks, and those of our business partners have been and may continue to be the target of cyber-attacks or information security breaches, which could lead to disruptions in critical systems, unauthorized release of confidential or protected information, corruption of data or other disruptions of our business operations. The ability of the information technology function to support our business in the event of a security breach or a disaster such as fire or flood and our ability to recover key systems and information from unexpected interruptions cannot be fully tested and there is a risk that, if such an event actually occurs, we may not be able to address immediately the repercussions of a breach. In the event of a breach, key information and systems may be unavailable for a number of days leading to an inability to conduct our business or perform some business processes in a timely manner. We have implemented strategies to mitigate the impact from these types of events.

In addition, the oil and gas industry has become increasingly dependent on digital technologies to conduct day-to-day operations including certain exploration, development and production activities. For example, software programs are used to interpret seismic data, manage drilling rigs, conduct reservoir modeling and reserves estimation, and to process and record financial and operating data. We depend on digital technology, including information systems and related infrastructure as well as cloud application and services, to process and record financial and operating data, communicate with our employees and business partners, analyze seismic and drilling information, estimate quantities of oil and gas reserves and for many other activities related to our business. Our business partners, including vendors, service providers, co-venturers, purchasers of our production, and financial institutions, are also dependent on digital technology. As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, have also increased.

A cyber-attack could include gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption, or result in denial-of-service on websites. Our technologies, systems, networks, and those of our business partners may become the target of cyber-attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information, or other disruption of our business operations. Our employees have been and will continue to be targeted by parties using fraudulent "spam" and "phishing" emails to misappropriate information or to introduce viruses or other malware through "trojan horse" programs to our computers. These emails appear to be legitimate emails sent by us but direct recipients to fake websites operated by the sender of the email or request that the recipient send a password or other confidential information through email or download malware. Despite our efforts to mitigate "spoof" and "phishing" emails through education, "spoof" and "phishing" activities remain a serious problem that may damage our information technology infrastructure.

Certain cyber incidents, such as surveillance, may remain undetected for an extended period. A cyber incident involving our information systems and related infrastructure, or that of our business partners, could disrupt our business plans and negatively impact our operations. Although to date we have not experienced any significant cyber-attacks, there can be no assurance that we will not be the target of cyber-attacks in the future or suffer such losses related to any cyber-incident. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.

## Risks relating to the countries in which we operate

Our operations may be adversely affected by political and economic circumstances in the countries in which we operate and in which we may operate in the future.

All of our current operations are located in South America. If local, regional or worldwide economic trends adversely affect the economy of any of the countries in which we have investments or operations, our financial condition and results from operations could be adversely affected.

Oil and natural gas exploration, development and production activities are subject to political and economic uncertainties (including but not limited to changes in energy policies or the personnel administering them), changes in laws and policies governing operations of foreign-based companies, expropriation of property, cancellation or modification of contract rights, revocation of consents or approvals, the obtaining of various approvals from regulators, foreign exchange restrictions, price controls, currency fluctuations, royalty increases and other risks arising out of foreign governmental sovereignty, as well as to risks of loss due to civil strife, acts of war and community-based actions, such as protests or blockades, guerilla activities, terrorism, acts of sabotage, territorial disputes and insurrection. In addition, we are subject both to uncertainties in the application of the tax laws in the countries in which we operate and to possible changes in such tax laws (or the application thereof), each of which could result in an increase in our tax liabilities. These risks are higher in developing countries, such as those in which we conduct our activities.

The main economic risks we face and may face in the future because of our operations in the countries in which we operate include the following:
• difficulties incorporating movements in international prices of crude oil and exchange rates into domestic prices;

• the possibility that a deterioration in Chile's, Colombia's, Argentina's, Peru's or Brazil's relations with multilateral credit institutions, such as the IMF, will impact negatively on capital controls, and result in a deterioration of the business climate;



• inflation, exchange rate movements (including devaluations), exchange control policies (including restrictions on remittance of dividends), price instability and fluctuations in interest rates;

• liquidity of domestic capital and lending markets;

• tax policies; and

• the possibility that we may become subject to restrictions on repatriation of earnings from the countries in which we operate in the future.

In addition, our operations in these areas increase our exposure to risks of guerilla activities, social unrest, local economic conditions, political disruption, civil disturbance, community protests or blockades, expropriation, piracy, tribal conflicts and governmental policies that may: disrupt our operations; require us to incur greater costs for security; restrict the movement of funds or limit repatriation of profits; lead to U.S. government or international sanctions; limit access to markets for periods of time; or influence the market’s perception of the risk associated with investments in these countries. Some countries in the geographic areas where we operate have experienced, and may experience in the future, political instability, and losses caused by these disruptions may not be covered by insurance. Consequently, our exploration, development and production activities may be substantially affected by factors which could have a material adverse effect on our results of operations and financial condition. We cannot guarantee that current programs and policies that apply to the oil and gas industry will remain in effect.

Our operations may also be adversely affected by laws and policies of the jurisdictions, including Bermuda, Colombia, Chile, Brazil, Argentina, Peru, Spain, the United Kingdom, the Netherlands and other jurisdictions in which we do business, that affect foreign trade and taxation, and by uncertainties in the application of, possible changes to (or to the application of) tax laws in these jurisdictions. For example, in 2018 the Colombian government introduced tax reforms with provisions that are effective January 1, 2019. See Note 16 to our Consolidated Financial Statements. With regards to Chile, although our CEOs have protection against tax changes through inviability tax clauses, potential issues may arise on certain aspects not clearly defined in current or future tax reforms.

Changes in any of these laws or policies or the implementation thereof, and uncertainty over potential changes in policy or regulations affecting any of the factors mentioned above or other factors in the future may increase the volatility of domestic securities markets and securities issued abroad by companies operating in these countries, which could materially and adversely affect our financial position, results of operations and cash flows. Furthermore, we may be subject to the exclusive jurisdiction of courts outside the United States or may not be successful in subjecting non-U.S. persons to the jurisdiction of courts in the United States, which could adversely affect the outcome of such dispute. Changes in tax laws may result in increases in our tax payments, which could materially adversely affect our profitability and increase the prices of our products and services, restrict our ability to do business in our existing and target markets and cause our results of operations to suffer. There can be no assurance that we will be able to maintain our projected cash flow and profitability following any increase in taxes applicable to us and to our operations.

The political and economic uncertainty in Brazil along with the ongoing “Lava Jato” investigations regarding corruption at Petrobras may hinder the growth of the Brazilian economy and could have an adverse effect on our business.

Our Brazilian operations represent 5% of our revenues as of December 31, 2018. The Brazilian economy has been experiencing a slowdown. Inflation, unemployment and interest rates have increased more recently and the Brazilian reais has weakened significantly in comparison to the US$. Our results of operations and financial condition may be adversely affected by the economic conditions in Brazil.

Petrobras and certain other Brazilian companies in the energy and infrastructure sectors are facing investigations by the Securities Commission of Brazil (Comissão de Valores Mobiliários), the U.S. Securities and Exchange Commission (the "SEC"), the Brazilian Federal Police and the Brazilian Federal Prosecutor's Office in connection with corruption allegations (the "Lava Jato" investigations). Depending on the duration and outcome of such investigations, the companies involved may face downgrades from rating agencies, funding restrictions and a reduction in their revenues. Given the significance of the companies under investigation including Petrobras, this could adversely affect Brazil's growth prospects and could have a protracted effect on the oil and gas industry. In addition to the recent economic crisis, protests, strikes and corruption scandals have led to a fall in confidence.

## We depend on maintaining good relations with the respective host governments and national oil companies in each of our countries of operation.

The success of our business and the effective operation of the fields in each of our countries of operation depend upon continued good relations and cooperation with applicable governmental authorities and agencies, including national oil companies such as Ecopetrol, ENAP, Petrobras, Petroperu and YPF. For instance, for the year ended December 31, 2018, 100% of our crude oil and condensate sales in Chile were made to ENAP, the Chilean state-owned oil company. In addition, our Brazilian operations in BCAM-40 Concession provide us with a long-term off-take contract with Petrobras, the Brazilian state-owned company that covers 100% of net proved gas reserves in the Manati Field, one of the largest non-associated gas fields in Brazil. If we, the respective host governments and the national oil companies are not able to cooperate with one another, it could have an adverse impact on our business, operations and prospects.

Oil and natural gas companies in Colombia, Chile, Brazil, Argentina and Peru do not own any of the oil and natural gas reserves in such countries.

Under Colombian, Chilean, Brazilian, Peruvian and Argentine law, all onshore and offshore hydrocarbon resources in these countries are owned by the respective



sovereign. Although we are the operator of the majority of the blocks and concessions in which we have a working and/or economic interest and generally have the power to make decisions as how to market the hydrocarbons we produce, the Chilean, Colombian, Brazilian, Peruvian and Argentine governments have full authority to determine the rights, royalties or compensation to be paid by or to private investors for the exploration or production of any hydrocarbon reserves located in their respective countries.

If these governments were to restrict or prevent concessionaires, including us, from exploiting oil and natural gas reserves, or otherwise interfered with our exploration through regulations with respect to restrictions on future exploration and production, price controls, export controls, foreign exchange controls, income taxes, expropriation of property, environmental legislation or health and safety, this could have a material adverse effect on our business, financial condition and results of operations.

Additionally, we are dependent on receipt of government approvals or permits to develop the concessions we hold in some countries. There can be no assurance that future political conditions in the countries in which we operate will not result in changes to policies with respect to foreign development and ownership of oil, environmental protection, health and safety or labor relations, which may negatively affect our ability to undertake exploration and development activities in respect of present and future properties, as well as our ability to raise funds to further such activities. Any delays in receiving government approvals in such countries may delay our operations or may affect the status of our contractual arrangements or our ability to meet contractual obligations.

## Oil and gas operators are subject to extensive regulation in the countries in which we operate.

The Colombian, Chilean, Brazilian, Peruvian and Argentine hydrocarbons industries are subject to extensive regulation and supervision by their respective governments in matters such as the environment, social responsibility, tort liability, health and safety, labor, the award of exploration and production contracts, the imposition of specific drilling and exploration obligations, taxation, foreign currency controls, price controls, export and import restrictions, capital expenditures and required divestments. In some countries in which we operate, such as Colombia, we are required to pay a percentage of our expected production to the government as royalties. See "Item 4. Information on the Company—B. Business Overview—Industry and regulatory framework—Colombia" and see Note 32.1 to our Consolidated Financial Statements. In Argentina, energy regulation gives absolute priority to domestic gas supply, which in case of a gas shortage occurs, will restrict our ability to fulfill our export commitments, if any. This regulation also established subsidies to domestic gas prices, which may negatively affect our revenues considering market prices. See "Item 4. Information on the Company—B. Business Overview—Industry and regulatory framework—Argentina."
For example, in Brazil there is potential liability for personal injury, property damage and other types of damages. Failure to comply with these laws and regulations also may result in the suspension or termination of operations or our being subjected to administrative, civil and criminal penalties, which could have a material adverse effect on our financial condition and expected results of operations. We expect to also operate in a consortium in some of our concessions, which, under the Brazilian Petroleum Law, establishes joint and strict liability among consortium members, and failure to maintain the appropriate licenses may result in fines from the ANP, ranging from R$10 to R$500 million. In addition, there is a contractual requirement in Brazilian concession agreements regarding local content, which has become a significant issue for oil and natural gas companies operating in Brazil given the penalties related with breaches thereof. The local content requirement will also apply to the production sharing contract regime. See "Item 4. Information on the Company—B. Business Overview—Our operations—Operations in Brazil."

Significant expenditures may be required to ensure our compliance with governmental regulations related to, among other things, licenses for drilling operations, environmental matters, drilling bonds, reports concerning operations, the spacing of wells, unitization of oil and natural gas accumulations, local content policy and taxation.

Colombia has experienced and continues to experience internal security issues that have had or could have a negative effect on the Colombian economy.

In 2016, the Colombian government and the Revolutionary Armed Forces of Colombia (FARC) signed a peace agreement, pursuant to which the FARC agreed to demobilize its troops and to hand over its weapons to a United Nations mission. Our business, financial condition and results of operations could be adversely affected by rapidly changing economic or social conditions, including the Colombian government’s response to current peace agreements and negotiations with other groups, including the ELN, which may result in legislation that increases our tax burden or that of other Colombian companies.

ELN has targeted crude oil pipelines in Colombia, including the Caño Limón-Coveñas pipeline, and other related infrastructure, disrupting the activities of certain oil and natural gas companies and resulting in unscheduled shutdowns of transportation systems. These activities, their possible escalation and the effects associated with them have had and may have in the future a negative impact on the Colombian economy or on our business, which may affect our employees or assets.

In addition, from time to time, community protests and blockades may arise near our operations in Colombia, which could adversely affect our business, financial condition or results of operations.

## Risks related to our common shares



An active, liquid and orderly trading market for our common shares may not develop and the price of our stock may be volatile, which could limit your ability to sell our common shares.

Our common shares began to trade on the New York Stock Exchange (the "NYSE") on February 7, 2014, and as a result have a limited trading history. We cannot predict the extent to which investor interest in our company will maintain an active trading market on the NYSE, or how liquid that market will be in the future.

The market price of our common shares may be volatile and may be influenced by many factors, some of which are beyond our control, including:

• our operating and financial performance and identified potential drilling locations, including reserve estimates;

• quarterly variations in the rate of growth of our financial indicators, such as net income per common share, net income and revenues;

• changes in revenue or earnings estimates or publication of reports by equity research analysts;

• fluctuations in the price of oil or gas;

• speculation in the press or investment community;

• sales of our common shares by us or our shareholders, or the perception that such sales may occur;

• involvement in litigation;

• changes in personnel;

• announcements by the company;

• domestic and international economic, legal and regulatory factors unrelated to our performance.

• variations in our quarterly operating results;

• volatility in our industry, the industries of our customers and the global securities markets;

• changes in our dividend policy;

• risks relating to our business and industry, including those discussed above;

• strategic actions by us or our competitors;

• actual or expected changes in our growth rates or our competitors' growth rates;

• investor perception of us, the industry in which we operate, the investment opportunity associated with our common shares and our future performance;

• adverse media reports about us or our directors and officers;

• addition or departure of our executive officers;

• change in coverage of our company by securities analysts;

• trading volume of our common shares;

• future issuances of our common shares or other securities;

• terrorist acts;

• the release or expiration of transfer restrictions on our outstanding common shares.

We have never declared or paid, and do not expect to pay in the foreseeable future, cash dividends on our common shares, and, consequently, your only opportunity to achieve a return on your

## investment is if the price of our stock appreciates.

We have never paid, and do not expect to pay in the foreseeable future, cash dividends on our common shares. Any decision to pay dividends in the future, and the amount of any distributions, is at the discretion of our board of directors and our shareholders, and will depend on many factors, such as our results of operations, financial condition, cash requirements, prospects and other factors. Due to losses resulting from the oil price decline in previous years, accumulated losses amount to US$206.7 million as of December 31, 2018.

We are also subject to Bermuda legal constraints that may affect our ability to pay dividends on our common shares and make other payments. Under the Companies Act, 1981 (as amended) of Bermuda (“Bermuda Companies Act”), we may not declare or pay a dividend if there are reasonable grounds for believing that we are, or would after the payment be, unable to pay our liabilities as they become due or that the realizable value of our assets would thereafter be less than our liabilities. We are also subject to contractual restrictions under certain of our indebtedness.

We are a holding company and our only material assets are our equity interests in our operating subsidiaries and our other investments; as a result, our principal source of revenue and cash flow is distributions from our subsidiaries; our subsidiaries may be limited by law and by contract in making distributions to us.

As a holding company, our only material assets are our cash on hand, the equity interests in our subsidiaries and other investments. Our principal source of revenue and cash flow is distributions from our subsidiaries. Thus, our ability to service our debt, finance acquisitions and pay dividends to our stockholders in the future is dependent on the ability of our subsidiaries to generate sufficient net income and cash flows to make upstream cash distributions to us. Our subsidiaries are and will be separate legal entities, and although they may be wholly-owned or controlled by us, they have no obligation to make any funds available to us, whether in the form of loans, dividends, distributions or otherwise. The ability of our subsidiaries to distribute cash to us will also be subject to, among other things, restrictions that are contained in our subsidiaries' financing and joint venture agreements, availability of sufficient funds in such subsidiaries and applicable state laws and regulatory restrictions. Claims of creditors of our subsidiaries generally will have priority as to the assets of such subsidiaries over our claims and claims of our creditors and stockholders. To the extent the ability of our subsidiaries to distribute dividends or other payments to us could be limited in any way, our ability to grow, pursue business opportunities or make acquisitions that could be beneficial to our businesses, or otherwise fund and conduct our business could be materially limited.

We may not be able to fully control the operations and the assets of our joint ventures and we may not be able to make major decisions or take



timely actions with respect to our joint ventures unless our joint venture partners agree. We may, in the future, enter into joint venture agreements imposing additional restrictions on our ability to pay dividends.

Sales of substantial amounts of our common shares in the public market, or the perception that these sales may occur, could cause the market price of our common shares to decline.

We may issue additional common shares or convertible securities in the future, for example, to finance potential acquisitions of assets, which we intend to continue to pursue. Sales of substantial amounts of our common shares in the public market, or the perception that these sales may occur, could cause the market price of our common shares to decline. This could also impair our ability to raise additional capital through the sale of our equity securities. Under our memorandum of association, we are authorized to issue up to 5,171,949,000 common shares, of which 60,483,447 common shares were outstanding as of December 31, 2018. We cannot predict the size of future issuances of our common shares or the effect, if any, that future sales and issuances of shares would have on the market price of our common shares.

Provisions of the Notes due 2024 could discourage an acquisition of us by a third party.

Certain provisions of the Notes due 2024 could make it more difficult or more expensive for a third party to acquire us or may even prevent a third party from acquiring us. For example, upon the occurrence of a fundamental change, holders of the Notes due 2024 will have the right, at their option, to require us to repurchase all of their notes at a purchase price equal to 101% of the principal amount thereof plus any accrued and unpaid interest (including any additional amounts, if any) to the date of purchase. By discouraging an acquisition of us by a third party, these provisions could have the effect of depriving the holders of our common shares of an opportunity to sell their common shares at a premium over prevailing market prices.

Certain shareholders have substantial control over us and could limit your ability to influence the outcome of key transactions, including a change of control.

Mr. Gerald E. O'Shaughnessy, our Chairman, Mr. James F. Park, our Chief Executive Officer, Mr. Jamie Coulter, director, Mr. Constantine Papadimitriou, director, and Mr. Juan Cristóbal Pavez, director, control 35.4% of our outstanding common shares as of March 15, 2019, holding the shares either directly or through privately held funds. As a result, these shareholders, if acting together, would be able to influence or control matters requiring approval by our shareholders, including the election of directors and the approval of amalgamations, mergers or other extraordinary transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. The concentration of ownership may have the effect of delaying, preventing or deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium for their common shares as part of a sale of our company and might ultimately affect the market price of our common shares. See "Item 7. Major Shareholders and Related Party Transactions—A. Major shareholders" for a more detailed description of our share ownership.

As a foreign private issuer, we are subject to different U.S. securities laws and NYSE governance standards than domestic U.S. issuers. This may afford less protection to holders of our common shares, and you may not receive corporate and company information and disclosure that you are accustomed to receiving or in a manner in which you are accustomed to receiving it.

As a foreign private issuer, the rules governing the information that we disclose differ from those governing U.S. corporations pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Although we intend to report quarterly financial results and report certain material events, we are not required to file quarterly reports on Form 10-Q or provide current reports on Form 8-K disclosing significant events within four days of their occurrence and our quarterly or current reports may contain less information than required under U.S. filings. In addition, we are exempt from the Section 14 proxy rules, and proxy statements that we distribute will not be subject to review by the SEC. Our exemption from Section 16 rules regarding sales of common shares by insiders means that you will have less data in this regard than shareholders of U.S. companies that are subject to the Exchange Act. As a result, you may not have all the data that you are accustomed to having when making investment decisions. For example, our officers, directors and principal shareholders are exempt from the reporting and "short-swing" profit recovery provisions of Section 16 of the Exchange Act and the rules thereunder with respect to their purchases and sales of our common shares. The periodic disclosure required of foreign private issuers is more limited than that required of domestic U.S. issuers and there may therefore be less publicly available information about us than is regularly published by or about U.S. public companies. See "Item 10. Additional Information—H. Documents on display."

As a foreign private issuer, we are exempt from complying with certain corporate governance requirements of the NYSE applicable to a U.S. issuer, including the requirement that a majority of our board of directors consist of independent directors as well as the requirement that shareholders approve any equity issuance by us which represents 20% or more of our outstanding common shares. As the corporate governance standards applicable to us are different than those applicable to domestic U.S. issuers, you may not have the same protections afforded under U.S. law and the NYSE rules as shareholders of companies that do not have such exemptions.

There are regulatory limitations on the ownership and transfer of our



common shares which could result in the delay or denial of any transfers you might seek to make.

The Bermuda Monetary Authority (the "BMA"), must specifically approve all issuances and transfers of securities of a Bermuda exempted company like us unless it has granted a general permission. We are able to rely on a general permission from the BMA to issue our common shares, and to freely transfer our common shares as long as the common shares are listed on the NYSE and/or other appointed stock exchange, to and among persons who are non-residents of Bermuda for exchange control purposes. Any other transfers remain subject to approval by the BMA and such approval may be denied or delayed.

We are a Bermuda company, and it may be difficult for you to enforce judgments against us or against our directors and executive officers.

We are incorporated as an exempted company under the laws of Bermuda and substantially all of our assets are located in Colombia, Chile, Argentina, Brazil and Peru. In addition, most of our directors and executive officers reside outside the United States and all or a substantial portion of the assets of such persons are located outside the United States. As a result, it may be difficult or impossible to effect service of process within the United States upon us, or to recover against us on judgments of U.S. courts, including judgments predicated upon the civil liability provisions of the U.S. federal securities laws. Further, no claim may be brought in Bermuda against us or our directors and officers in the first instance for violation of U.S. federal securities laws because these laws have no extraterritorial application under Bermuda law and do not have force of law in Bermuda. However, a Bermuda court may impose civil liability, including the possibility of monetary damages, on us or our directors and officers if the facts alleged in a complaint constitute or give rise to a cause of action under Bermuda law.

There is no treaty in force between the United States and Bermuda providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. As a result, whether a United States judgment would be enforceable in Bermuda against us or our directors and officers depends on whether the U.S. court that entered the judgment is recognized by the Bermuda court as having jurisdiction over us or our directors and officers, as determined by reference to Bermuda conflict of law rules. A judgment debt from a U.S. court that is final and for a sum certain based on U.S. federal securities laws will not be enforceable in Bermuda unless the judgment debtor had submitted to the jurisdiction of the U.S. court, and the issue of submission and jurisdiction is a matter of Bermuda (not U.S.) law.

In addition, and irrespective of jurisdictional issues, the Bermuda courts will not enforce a U.S. federal securities law that is either penal or contrary to Bermuda public policy. An action brought pursuant to a public or penal law, the purpose of which is the enforcement of a sanction, power or right at the instance of the state in its sovereign capacity, will not be entertained by a Bermuda court. Certain remedies available under the laws of U.S. jurisdictions, including certain remedies under U.S. federal securities laws, would not be available under Bermuda law or enforceable in a Bermuda court, as they would be contrary to Bermuda public policy.

The transfer of our common shares may be subject to capital gains taxes pursuant to indirect transfer rules in Chile.

In September 2012, Chile established “indirect transfer rules,” which impose taxes, under certain circumstances, on capital gains resulting from indirect transfers of shares, equity rights, interests or other rights in the equity, control or profits of a Chilean entity, as well as on transfers of other assets and property of permanent establishments or other businesses in Chile (“Chilean Assets”). As we indirectly own Chilean Assets, the indirect transfer rules would apply to transfers of our common shares provided certain conditions outside of our control are met. If such conditions were present and as a result the indirect transfer rules were to apply to sales of our common shares, such sales would be subject to indirect transfer tax on the capital gain realized in connection with such sales. For a description of the indirect transfer rules and the conditions of their application see “Item 10. Additional Information—E. Taxation—Chilean tax on transfers of shares.”

As an exempted company incorporated under Bermuda law, our operations may be subject to economic substance requirements.

On December 5, 2017, following an assessment of the tax policies of various countries by the Code of Conduct Group for Business Taxation of the European Union (the "COCG"), the Council of the EU approved and published Council conclusions containing a list of non-cooperative jurisdictions for tax purposes (the "Conclusions"). Although not considered so-called "non-cooperative jurisdictions," certain countries, including Bermuda, were listed as having "tax regimes that facilitate offshore structures which attract profits without real economic activity." In connection with the Conclusions, and to avoid being placed on the list of "non-cooperative jurisdictions," the government of Bermuda, among others, committed to addressing COCG proposals relating to economic substance for entities doing business in or through their respective jurisdictions and to pass legislation to implement any appropriate changes by the end of 2018.

The Economic Substance Act 2018 and the Economic Substance Regulations 2018 of Bermuda (the “Economic Substance Act” and the “Economic Substance Regulations”, respectively) became operative on December 31, 2018. The Economic Substance Act applies to every registered entity in Bermuda that engages in a relevant activity and requires that every such entity shall maintain a substantial economic presence in Bermuda. Relevant activities for the purposes of the Economic Substance Act are banking business, insurance business, fund management business, financing business, leasing business,



headquarters business, shipping business, distribution and service center business, intellectual property holding business and conducting business as a holding entity, which may include a pure equity holding entity.

The Bermuda Economic Substance Act provides that a registered entity that carries on a relevant activity complies with economic substance requirements if (a) it is directed and managed in Bermuda, (b) its core income-generating activities (as may be prescribed) are undertaken in Bermuda with respect to the relevant activity, (c) it maintains adequate physical presence in Bermuda, (d) it has adequate full time employees in Bermuda with suitable qualifications and (e) it incurs adequate operating expenditure in Bermuda in relation to the relevant activity.

A registered entity that carries on a relevant activity is obliged under the Bermuda Economic Substance Act to file a declaration in the prescribed form (the “Declaration”) with the Registrar of Companies (the “Registrar”) on an annual basis.

The Economic Substance Regulations provide that minimum economic substance requirements shall apply in relation to an entity if the entity is a pure equity holding entity which only holds or manages equity participations, and earns passive income from dividends, distributions, capital gains and other incidental income only. The minimum economic substance requirements include a) compliance with applicable corporate governance requirements set forth in the Bermuda Companies Act 1981 including keeping records of account, books and papers and financial statements and b) submission of an annual economic substance declaration form. Additionally, the Economic Substance Regulations provide that a pure equity holding entity complies with economic substance requirements where it also has adequate employees for holding and managing equity participations, and adequate premises in Bermuda.

If we fail to comply with our obligations under the Bermuda Economic Substance Act or any similar law applicable to us in any other jurisdictions, we could be subject to financial penalties and spontaneous disclosure of information to foreign tax officials in related jurisdictions and may be struck from the register of companies in Bermuda or such other jurisdiction. Any of these actions could have a material adverse effect on our business, financial condition and results of operations.

On March 12, 2019, Bermuda was placed by the EU on its list of non-cooperative jurisdictions for tax purposes due to an issue with Bermuda's economic substance legislation which was not resolved in time for the EU's deadline. At present, the impact of being included on the list of non-cooperative jurisdictions for tax purposes is unclear. While Bermuda has now amended its legislation which the Bermuda Government has stated has addressed this issue and expects to be removed from the list of non-cooperative jurisdictions at the EU's Economic and Financial Affairs Council's next meeting which is scheduled to be in May 2019, there can be no assurance that Bermuda will be removed from such list. If Bermuda is not removed from the list and sanctions or other financial, tax or regulatory measures were applied by European Member States to countries on the list or further economic substance requirements were imposed by Bermuda, our business could be negatively impacted.

## ITEM 4. INFORMATION ON THE COMPANY

## A. History and development of the company

## General

We were incorporated as an exempted company pursuant to the laws of Bermuda as GeoPark Holdings Limited in February 2006. On July 30, 2013, our shareholders approved a change in our name to GeoPark Limited, effective from July 31, 2013. We maintain a registered office in Bermuda at Cumberland House, 9th Floor, 1 Victoria Street, Hamilton HM 11, Bermuda. Our principal executive offices are located at Nuestra Señora de los Ángeles 179, Las Condes, Santiago, Chile, telephone number +562 2242 9600, Street 94 N° 11-30, 8, 9, 8th floor, Bogotá, Colombia, telephone number +57 1 743 2337, and Florida 981, 1st floor, Buenos Aires, Argentina, telephone number +5411 4312 9400.

The SEC maintains an internet website that contains reports, proxy, information statements and other information about issuers, like us, that file electronically with the SEC. The address of that website is www.sec.gov. The Company's website address is www.geo-park.com. The information contained on, or that can be accessed through, the Company's website is not part of, and is not incorporated into, this Annual Report.

## Our Company

We are a leading independent oil and natural gas exploration and production ("E&P") company with operations in Latin America and a proven track record of growth in production and reserves since 2006. We operate in Colombia, Chile, Brazil, Argentina and Peru. We are focused on Latin America because we believe it is one of the most important regions globally in terms of hydrocarbon potential, with less presence of independent E&P companies compared to the United States and Canada. In this region, much of the acreage has historically been controlled or owned by state-owned companies. We believe that these factors create an opportunity for smaller, more agile companies like us to build a long-term business.

We produced a net average of 36.0 mboepd during the year ended December 31, 2018, of which 79%, 8%, 5% and 8% were, respectively, in Colombia, Chile, Argentina and Brazil, and of which 85% was oil. As of August 31, 2018, we were ranked as the third largest oil operator in Colombia, where we made the largest new oil field discovery in the last 20 years. We are the first private oil and gas operator in Chile and we are operating the inaugural project of Petropéru in its return to the upstream business in Peru. We partnered with Petrobras in one of Brazil's largest producing gas fields and we have recently increased our activities in Argentina with the acquisition of three blocks in the Neuquén Basin in March 2018.



We have built our company around three principal capabilities:

• as an Explorer, which is our ability, experience, methodology and creativity to find and develop oil and gas reserves in the subsurface, based on the best science, solid economics and ability to take the necessary managed risks.

• as an Operator, which is our ability to execute in a timely manner and to have the know-how to profitably drill for, produce, treat, transport and sell our oil and gas – with the drive and persistence to find solutions, overcome obstacles, seize opportunities and achieve results.

• as a Consolidator, which is our ability and initiative to assemble the right balance and portfolio of upstream assets in the right hydrocarbon basins in the right regions with the right partners and at the right price – coupled with the visions and skills to transform and improve value above ground.

We believe that our risk and capital management policies have enabled us to compile a geographically diverse portfolio of properties that balances exploration, development and production of oil and gas. These attributes have also allowed us to raise capital and to partner with premier international companies. Most importantly, we believe we have developed a distinctive culture within our organization that promotes and rewards trust, partnership, entrepreneurship and merit. Consistent with this approach, all of our employees are eligible to participate in our long-term incentive program, which is the Performance-Based Employee Long-Term Incentive Program. See “Item 6. Directors, Senior Management and Employees—B. Compensation—Equity Incentive Compensation—Performance-Based Employee Long-Term Incentive Program.”

Our regional platform and risk-balanced portfolio has been built following a proactive but conservative long term technical approach, converting projects into successful value-generating assets.

## History

We were founded in 2002 by Gerald E. O'Shaughnessy and James F. Park, who have over 40 years of international oil and natural gas experience, respectively. Mr. O'Shaughnessy currently serves as our Chairman and Mr. Park currently serves as our Chief Executive Officer and Deputy Chairman.

We are a leading independent oil and natural gas exploration and production (“E&P”), company with operations in Latin America and a proven track record of growth in production and reserves since 2006. We operate in Colombia, Chile, Brazil, Argentina and Peru.

Our History can be summarized by our growth in each country and our performance in the capital markets:

## Chile

In 2006, after demonstrating our technical expertise and committing to an exploration and development plan, we obtained a 100% operating working interest in the Fell Block from the Republic of Chile. In 2008 and 2009, we continued our growth in Chile by acquiring operating working interests in each of the Otway and Tranquilo Blocks. Then, in 2011, ENAP awarded us the opportunity to obtain operating working interests in each of the Isla Norte, Flamenco and Campanario Blocks in Tierra del Fuego, Chile, which we refer to collectively as the Tierra del Fuego Blocks, and in 2012, jointly with ENAP, we entered into CEOPs with Chile for the exploration and exploitation of hydrocarbons within these blocks.

Also, in 2011, LGI acquired a 20% equity interest in GeoPark Chile and a 14% equity interest in GeoPark TdF for US$148.0 million.

Finally, in November 2018, we acquired all of LGI's equity interest in GeoPark's Chilean and Colombian subsidiaries. This acquisition increased GeoPark's equity interest to 100% in its Colombian and Chilean businesses. The acquisition price includes a fixed payment of US$81 million already paid at closing, plus two equal installments of US$15 million each, to be paid in June 2019 and June 2020. Additionally, three contingent payments of US$5 million each could be payable over the next three years, subject to certain production thresholds being exceeded.

## Colombia

In the first quarter of 2012, we moved into Colombia by acquiring three privately held E&P companies: (i) Winchester Oil and Gas S.A., a Colombian branch of a sociedad anónima incorporated under the laws of Panama, which merged into GeoPark Colombia SAS ("Winchester"), (ii) La Luna Oil Company Limited S.A., a sociedad anónima incorporated under the laws of Panama, which merged into GeoPark Colombia SAS ("Luna") and (iii) Hupecol Cuerva LLC, a limited liability company incorporated under the laws of the state of Delaware, which merged into GeoPark Colombia SAS ("Cuerva"). These acquisitions provided us with an attractive platform of reserves and resources in Colombia.

In December 2012, LGI acquired a 20% equity interest in GeoPark Colombia Coöperatie U.A by making a US$14.9 million capital contribution and assuming the existing debt for an amount of US$4.9 million.

## Brazil

In May 2013, we entered into agreements to expand our operations to Brazil. As of 2014, following the Rio das Contas acquisition, we have a 10% working interest in the BCAM-40 Concession, which includes an interest in the Manati Field operated by Petrobras.

Since 2013, we have participated in the Brazilian ANP Bid Rounds and have been awarded exploratory concessions in each one of them.

## Argentina

In August 2014, in partnership with Pluspetrol, a private oil and gas company with strong presence across Latin America, we were awarded two exploration licenses in the Sierra del Nevado and Puelen Blocks, as part of the 2014 Mendoza Bidding Round in Argentina.



In July 2015, we signed a farm-in agreement with Wintershall for the CN-V Block in the Mendoza Province.

Additionally, in December 2017, we agreed to purchase from Pluspetrol, a 100% working interest and operatorship of the Aguada Baguales, El Porvenir and Puesto Touquet blocks in Argentina. We entered into an asset purchase agreement with Pluspetrol, dated December 18, 2017 (the "APA"). The transaction closed on March 27, 2018.

Finally, in June 2018, we entered into a partnership with YPF, the state-owned oil company of Argentina, on the Los Parlamentos block – a large high potential block in the Neuquén Basin with both conventional and unconventional prospects.

## Peru

In October 2014, we expanded our footprint into Peru by acquiring the Morona Block in a joint venture with Petroperu. This transaction awarded us a 75% working interest of the Morona Block. In December 2016, we obtained final regulatory approval for our acquisition of the Morona Block in Peru. The Joint Investment and Operating Agreement dated October 1, 2014 and its amendments were closed on December 1, 2016, following the issuance of Supreme Decree 031-2016-MEM.

## New potential country platform

In December 2015, as part of our long-term effort to build an upstream platform in Mexico, we participated in the Mexican Bid Round 1.3 with Grupo Alfa for onshore projects, however, no blocks were awarded to us.

In March 2019, we announced our expected entry into Ecuador through the acquisition of the Espejo and Perico exploratory blocks in the Intracampos Bid Round in the Oriente Basin located in the north-eastern part of Ecuador. The blocks were awarded to the GeoPark and Frontera consortium (50% GeoPark, 50% Frontera) in the form of production sharing contracts. The final award is contingent upon regulatory approvals and the execution of the contracts is expected for the second quarter of 2019. See "Item 3. Key Information—A. Risk Factors—Risks relating to our business—Our pending acquisition of the Espejo and Perico blocks in Ecuador is subject to regulatory approvals."

## Funding

In February 2013, we issued US$300 million aggregate principal amount of 7.50% senior secured notes due 2020 (the "Notes due 2020"). We repurchased US$284 million aggregate principal amount of the outstanding Notes due 2020 in September 2017 and redeemed the remaining US$16 million aggregate principal amount outstanding in October 2017.

In February 2014, we commenced trading on the NYSE and raised US$98 million (before underwriting commissions and expenses), including the overall allotment option granted to and exercised by the underwriters, through the issuance of 13,999,700 common shares.
In September 2017, we issued US$425.0 million aggregate principal amount of 6.50% senior notes due 2024. The net proceeds from the Notes were used by us (i) to make a capital contribution to our wholly-owned subsidiary, GeoPark Latin America Limited Agencia en Chile, providing it with sufficient funds to fully repay the Notes due 2020 and to pay any related fees and expenses, including a call premium, and (ii) for general corporate purposes, including capital expenditures, such as the acquisition of Aguada Baguales, El Porvenir and Puesto Touquet blocks in the Neuquén Basin in Argentina, to repay existing indebtedness, including the Itaú loan.

## B. Business Overview

We have grown our business through drilling, developing and producing oil and gas, winning new licenses and acquiring strategic assets and businesses. Since our inception, we have supported our growth through our prospect development efforts, drilling program, long-term strategic partnerships and alliances with key industry participants, accessing debt and equity capital markets, developing and retaining a technical team with vast experience and creating a successful track record of finding and producing oil and gas in Latin America. A key factor behind our success ratio is our experienced team of geologists, geophysicists and engineers, including professionals with specialized expertise in the geology of Colombia, Chile, Brazil, Argentina and Peru.

The following map shows the countries in which we have blocks with working and/or economic interests as of December 31, 2018. For information on our working interests in each of these blocks, see “—Our assets” below.




 \( ^{(1)} \)  On November 2, 2018, GeoPark and Perenco Oil and Gas executed a purchase and sale agreement in which Perenco agreed to purchase GeoPark's 100% working interest in the La Cuerva and Yamu blocks.

 \( ^{(1)} \) We acquired the Neuquén Blocks in March 2018. Production figures do not include production prior to their acquisition by us.

## Our assets

We have a well-balanced portfolio of assets that includes working and/or economic interests in 25 hydrocarbon blocks, 24 of which are onshore blocks, including 10 in production as of December 31, 2018. Our assets give us access to more than 5 million gross exploratory and productive acres.

According to the D&M Reserves Report, as of December 31, 2018, the blocks in Colombia, Chile, Brazil, Argentina and Peru in which we have a working interest had 108.4 mmboe of net proved reserves, with 69%, 6%, 3%, 5% and 17% of such net proved reserves located in Colombia, Chile, Brazil, Argentina and Peru, respectively.



We produced a net average of 36.0 mboepd during the year ended December 31, 2018 of which 79%, 8%, 5% and 8%, were in Colombia, Chile, Argentina and Brazil, respectively, and of which 85% was oil.

We are the operator of the majority of the blocks in which we have a working interest.

## Our strengths

We believe that we benefit from the following competitive strengths:

## High quality and diversified asset base built through a successful track record of organic growth and acquisitions

Our assets include a diverse portfolio of oil and natural gas-producing reserves, operating infrastructure, operating licenses and valuable geological surveys in Latin America. Throughout our history, we have delivered continuous growth in our production, and our management team has been able to identify under-exploited assets and turn them into valuable, productive assets, and to allocate resources effectively based on prevailing conditions.

• Colombia. In 2012, we acquired assets in Colombia at attractive prices, which gave us access to exploratory and productive acres with many prospects. In the Llanos Basin, we pioneered a new play type combining structural and stratigraphic traps. As a result, in the Llanos 34 Block our average daily production has grown from 0 at the time of acquisition to more than 30,400 bopd as of December 31, 2018.

• Chile. In 2002, we acquired a non-operating working interest in the Fell Block in Chile, which at the time had no material oil and gas production or reserves despite having been actively explored and drilled over the course of more than 50 years. Since 2006, when we became the operator of the Fell Block we performed active exploration and development drilling that resulted in multiple oil and gas discoveries.

• Brazil. Since 2013, we have participated in the Brazilian ANP Bid Rounds and were awarded exploratory concessions in each one of them. In 2014, we acquired Rio das Contas, which gave us a 10% working interest in the BCAM-40 Concession, including the shallow-depth offshore Manati and Camarão Norte Fields in the Camamu-Almada Basin in the State of Bahia, which has consistently self-funded its operations. The Manati Field has provided up to 3.7% of total gas produced in Brazil.

• Argentina. During 2014, GeoPark and Pluspetrol were awarded two exploration licenses in the Sierra del Nevado and Puelen Blocks as part of the 2014 Mendoza Bidding Round in Argentina, carried out by Empresa Mendocina de Energía S.A. (“EMESA”). In 2015, we acquired a 50% working interest in the CN-V Block in Mendoza from Wintershall Energía S.A. On December 18, 2017, we executed an asset purchase agreement (the “APA”) with Pluspetrol to acquire a 100% working interest and operatorship of the Aguada Baguales, El Porvenir and Puesto Touquet blocks in Argentina. Closing of the transaction occurred on March 27, 2018.

• Peru. In December 2016, we expanded our footprint into Peru by acquiring the Morona Block in a joint venture with Petroperu. The Morona Block contains the Situche Central proven oil field, which we believe offers extensive exploration potential with several potential high impact prospects and plays. See “—Our operations—Operations in Peru.”

## Significant drilling inventory and resource potential from existing asset base

Our portfolio includes large land holdings in high-potential hydrocarbon basins and blocks with multiple drilling leads and prospects in different geological formations, which provide several attractive opportunities with varying levels of risk. Our drilling inventory and our development plans target locations that provide attractive economics and support a predictable production profile, as demonstrated by our expansions in Colombia.

Our geoscience team continues to identify new potential accumulations and expand our inventory of prospects and drilling opportunities.

## Continue to grow a risk-balanced asset portfolio

We intend to continue to focus on maintaining a risk-balanced portfolio of assets, combining cash flow-generating assets with upside potential opportunities, and on increasing production and reserves through finding, developing and producing oil and gas reserves in the countries in which we operate. In general, when we enter a new country we look for a mix of three elements: (i) producing fields, or existing discoveries with near-term possibility of production, to generate cash flows; (ii) an inventory of adjacent low-risk prospects that can offer medium-term upside for steady growth; and (iii) a periphery of higher-risk projects which have a potential to generate significant upside in the long run.

For example, in Colombia, we acquired three companies simultaneously to pursue a risk-balanced approach: one company had mainly proven production and reserves to provide us with a steady cash flow base, and the remaining had highly prospective exploration license blocks. Within four years of entering Colombia, we made multiple oil discoveries in block Llanos 34 that allowed us to increase production and cash flows.

We believe this approach will allow us to sustain continuous and profitable growth and also participate in higher risk growth opportunities with upside potential. See “—Our operations.”

## Platform and Funding

We are focused on continued growth utilizing a disciplined capital structure and a conservative financial philosophy. Due to the volatile nature of commodity prices, expenditure discipline and a focus on disciplined capital structure are critical to our business. Our multi-country platform and asset portfolio is managed through our capital allocation methodology, which also allows us to quickly adapt and grow. Under this methodology, each country, has a local team running the business who recommends and advocates for the projects with which they want to move forward. The corporate team then ranks all of the projects based on economic, technical and strategic criteria,



for the purpose of comparing projects. This also creates opportunities for improvements in the projects that can, in turn, improve their ranking. Finally, once the production and reserve growth targets are defined, the corporate team decides the amount of capital to be invested and allocates that capital to the highest value-adding projects. As an example, for the 2019 capital allocation process, over 135 projects were presented with a final selection of 74 which comprise our 2019 work program, under the base capital program. Additionally, given the inherent oil price volatility, we design our work programs to be flexible, which means that they can be increased or decreased depending on the oil price scenario.

We have historically benefited from access to debt and equity capital markets and cash flows from operations, as well as other funding sources, which have provided us with funds to finance our organic growth and the pursuit of potential new opportunities.

We generated US$256.2 million and US$142.2 million in cash from operations in the years ended December 31, 2018 and 2017, respectively, and had US$127.7 million and US$134.8 million of cash and cash equivalents as of December 31, 2018 and 2017, respectively.

As of December 31, 2018, we had US$447.0 million of total outstanding indebtedness and over 96% of our debt had a maturity of 2024.

During October 2018, we entered into a loan agreement with Banco Santander for Brazilian Real 77.6 million (equivalent to US$ 20 million at the moment of the loan execution) to repay an existing US\)-denominated intercompany loan, which matures in October 2020. As a result of this transaction, our Brazilian subsidiary has significantly reduced its exposure to foreign currency fluctuation.

In September 2017, we issued US$425.0 million aggregate principal amount of 6.50% senior notes due 2024 (the "Notes due 2024"). The Notes due 2024 contain incurrence-based limitations on the amount of indebtedness we can incur, see "Item 5. Operating and Financial Review and Prospects—Liquidity and capital resources—Indebtedness—Notes due 2024—Covenants."

In December 2015, we entered into an offtake and prepayment agreement with Trafigura under which we sold and delivered a portion of our Colombian crude oil production to Trafigura. The offtake agreement also provided us with prepayment line of up to US$100 million, subject to applicable volumes corresponding to the terms of the agreement, in the form of prepaid future oil sales.

In March 2014, we borrowed US$70.5 million pursuant to a five-year term variable interest secured loan, secured by the benefits we receive under the Purchase and Sale Agreement for Natural Gas with Petrobras, equal to 6-month LIBOR + 3.9% to finance part of the purchase price of our Rio das Contas acquisition. In March 2015, we reached an agreement to: (i) extend the principal payments that were due in 2015 (amounting to approximately US$15 million), which were divided pro-rata during the remaining principal installments, starting in March 2016 and (ii) to increase the variable interest rate equal to the 6-month LIBOR + 4.0%. The loan was fully repaid in September 2017.

In February 2014, we commenced trading on the NYSE and raised US$98 million (before underwriting commissions and expenses), including the overallotment option granted to and exercised by the underwriters, through the issuance of 13,999,700 common shares.

## Strong cash flow

We benefit from a strong cash flow from operating activities. For the year ended December 31, 2018, cash provided by operating activities was US256.2 million. Our cash flow from operating activities plays a significant role in funding our capital expenditures.

## Maintain financial strength

We seek to maintain a prudent and sustainable capital structure and a strong financial position to allow us to maximize the development of our assets and capitalize on business opportunities as they arise. We intend to remain financially disciplined by limiting substantially all our debt incurrence to identified projects with repayment sources. We expect to continue benefiting from diverse funding sources such as our partners and customers in addition to the international capital markets.

Our cash flow generation is complemented by our financial hedging program. Since October 2016, we have entered into derivative financial instruments to manage our exposure to oil price risk. The purpose of our hedging strategy is to establish minimum oil prices to secure a stable cash flow and the execution of our work program. For the period commencing January 2018 to December 2018, we hedged between 13,000 and 14,000 bpd via zero premium collars and three-way hedges (US$10/bbl wide put spread and call), with a minimum average Brent price of US$55 per barrel and a maximum average price of US$73 per barrel, representing 44% of our oil production for that period. For the period from January 2019 to March 2019, we have secured 15,000 bpd with a minimum average price of US$64 per barrel and a maximum average price of US$92 per barrel via zero premium collars and three-way hedges (US$10/bbl wide put spread and call). For the period from April 2019 to June 2019, we have secured 11,000 bpd with a minimum average price of US$65 per barrel and a maximum average price of US$91 per barrel via zero premium collars and three-way hedges (US$10/bbl wide put spread and call). For the period commencing July 2019 to September 2019, we have secured 5,000 bpd with a minimum average price of US$65 per barrel and a maximum average price of US$92 per barrel via zero premium collars.

In December 2018 we decided to manage our future exposure to local currency fluctuation with respect to income tax balances in Colombia. Consequently, we entered into a derivative financial instrument with a local



bank in Colombia, for an amount equivalent to US$ 92.1 million, in order to anticipate any currency fluctuation with respect to income taxes to be paid during the first half of 2019.

We believe that by maintaining a disciplined capital structure and a conservative financial philosophy, including limiting our debt incurrence to specified projects with repayment sources and our use of financial hedges, we are positioned to maintain sufficient liquidity and remain flexible in volatile commodity price environments. Our financial flexibility also gives us the ability to pursue new opportunities through future potential acquisitions.

## Pursue strategic acquisitions in Latin America

We have historically benefited from, and intend to continue to grow through, strategic acquisitions in Latin America. These acquisitions have provided us with additional attractive platforms in the region. Our Colombian acquisitions, for example, highlight our ability to identify and execute on attractive growth opportunities, as we have grown to become the third largest operator in Colombia. We acquired our interest in the Llanos 34 Block in the first quarter of 2012 for US$30 million and have achieved 1P reserve PV-10 of US$1,340 million as of December 31, 2018. Our enhanced regional portfolio, including investment-grade countries and strong partnerships, position us as a regional consolidator. We intend to continue to grow through strategic acquisitions in other countries in Latin America, which we may consider from time to time.

Our acquisition strategy is aimed at maintaining a balanced portfolio of lower-risk cash flow-generating properties and assets that have upside potential, keeping a balanced mix of oil and gas-producing assets (though we expect to remain weighted towards oil) and focusing on both assets and corporate targets.

## Maintain a high degree of operatorship to control production costs

As of the date of this annual report, we are and intend to continue to be the operator of a majority of the blocks and concessions in which we have working interests. Operating the majority of our blocks and concessions gives us the flexibility to allocate our capital and resources opportunistically and efficiently within a diversified asset portfolio. We believe that this strategy has allowed, and will continue to allow us, to leverage our unique culture, focused on excellence, and our talented technical, operating and management teams. For example, as commodity prices were projected to decline throughout 2015, we announced in the first quarter of 2015 a decision to shift our development plan primarily to our operations in the Llanos 34 Block to focus on the Llanos Basin, which had demonstrated strong returns on capital. Our operating team reacted quickly to pivot our operations that were unburdened by drilling obligations and worked with our service partners to coordinate a smooth and efficient transition to a new plan. Since then we were able to control production costs, as exemplified by our average operating costs for the Llanos 34 Block, which were US$4.0 per boe for the year ended December 31, 2018.

Long-term strategic partnerships and strong strategic relationships provide us with additional funding flexibility to pursue further acquisitions

We benefit from a number of strong partnerships and relationships. In Chile, we believe we have strong long-term commercial relationships with Mathexane and ENAP, and in Colombia, we believe we have developed a strong relationship with Ecopetrol, the Colombian state-owned oil and gas company. In Brazil, we believe we will continue to derive benefits from the long-term relationship GeoPark Brazil has with Petrobras.

In February 2018, we announced the formation of a new long-term strategic partnership to jointly acquire, invest in, and create value from upstream oil and gas projects with the objective of building a large-scale, economically-profitable and risk-balanced portfolio of assets and operations across Latin America with ONGC Videsh, the wholly-owned subsidiary and international arm of Oil and Natural Gas Corporation Limited, India's national oil company.

Maintain our commitment to environmental, safety and social responsibility

A major component of our business strategy is our focus on and commitment to our environmental and social responsibilities, in line with international standards. We see this as a fundamental element of ensuring long-term business initiatives. We are committed to minimizing the impact of our projects on the environment and aim to create mutually beneficial relationships with the local communities in which we operate in order to enhance our ability to create sustainable value in our projects. These commitments are embodied in our in-house designed Environmental, Health, Safety and Security management program, which we refer to as "S.P.E.E.D." (Safety, Prosperity, Employees, Environment and Community Development). Our S.P.E.E.D. program was developed in accordance with several international quality standards, including ISO 14001 (for environmental management issues), OHSAS 18001 (for occupational health and safety management issues), ISO 26000 (for social accountability and workers' rights issues), and applicable World Bank standards. See "—Health, safety and environmental matters."

During 2016, we began the ISO 14001 certifying process through programs related to the efficient use of natural resources and compliance with environmental regulation. We have also provided training to our staff and the communities in which we operate with respect to these matters.

In August 2017, we obtained the ISO 14001:2015 certification for our environmental management process for the design, construction, operation, maintenance, modernization and dismantlement of GeoPark Colombia S.A.S's facilities, and the performance of exploration and oil and gas production activities in the Llanos 34 and VIM-3 blocks with a commitment to continuously improve our processes.

Highly committed founding shareholders and technical and management teams with proven industry expertise and technically-driven culture

Our founding shareholders, management and operating teams have significant experience in the oil and gas industry and a proven technical and commercial performance record in onshore fields, as well as complex projects



in Latin America and around the world, including expertise in identifying acquisition and expansion opportunities. Moreover, we differentiate ourselves from other E&P companies through our technically-driven culture, which fosters innovation, creativity and timely execution. Our geoscientists, geophysicists and engineers are pivotal to the success of our business strategy, and we have created an environment and supplied the resources that enable our technical team to focus its knowledge, skills and experience on finding and developing oil and gas fields.

In addition, we strive to provide a safe and motivating workplace for employees in order to attract, protect, retain and train a quality team in the competitive marketplace for capable energy professionals.

Our CEO, Mr. James F. Park, has been involved in E&P projects in Latin America since 1978. He has been closely involved in grass-roots exploration activities, drilling and production operations, surface and pipeline construction, legal and regulatory issues, crude oil marketing and transportation and capital raising for the industry. As of March 15, 2019, Mr. Park held 13.2% of our outstanding common shares.

Our Chairman, Mr. Gerald O'Shaughnessy, has been actively involved in the oil and gas business internationally and in North America since 1976. As of March 15, 2019, Mr. O'Shaughnessy held 11.5% of our outstanding common shares.

Our management and operating team has an average experience in the energy industry of more than 25 years in companies such as Chevron, ENAP, Petrobras, Pluspetrol, San Jorge, Total and YPF, among others. Throughout our history, our management and operating team has had success in unlocking unexploited value from previously underdeveloped assets.

In addition, as of March 15, 2019, our executive directors and key management (excluding our founding shareholders, Mr. Gerald E. O'Shaughnessy and Mr. James F. Park) owned 30.7% of our outstanding common shares, aligning their interests with those of our shareholders and helping retain the talent we need to continue to support our business strategy. See "Item 6. Directors, Senior Management and Employees—B. Compensation." Our founding shareholders are also involved in our daily operations and strategy.

## Technically-driven culture and capitalization of local knowledge

We intend to continue to pursue strategies that maximize value. For this purpose, we intend to continue expanding our technical teams and to foster a culture that rewards talent according to results. For example, we have been able to maintain the technical teams we inherited through our Colombian and Brazilian acquisitions. We believe local technical and professional knowledge is key to operational and long-term success and intend to continue to secure local talent as we grow our business in different locations.

## Innovation

We are committed to an innovation culture driven by the continuous search and application of state-of-the-art technologies, agile processes and creative new solutions to challenges in both our fields and our offices. Our guiding principle is that everyone can innovate, and this is promoted through a cross-collaborative and trust-based work environment. To ensure that this is taken as a key priority, as of 2018 we have included innovation as one of our metrics in our Balanced Scorecard and have allocated seed money in our annual budget to kick-start new projects. As an example of the success we have had, in 2018 we were awarded a prize for innovative road safety measures by the Colombian Council of Security. Additionally, we have successfully implemented multiple new technology-based projects, such as cryobox virtual gas technology in Neuquén Province, in Argentina, to put into production a well that was previously shut-in due to a lack of facilities, and a gas based artificial lift system for mature wells in Chile that results in low maintenance costs.

## 2019 Strategy and Outlook

Oil prices have been volatile since the end of 2014. In preparation for continued volatility, we have developed multiple scenarios for our 2019 capital expenditure program.

Our preliminary base capital program for 2019 considers a reference oil price assumption of US$70 per barrel and calls for approximately US$220-240 million to fund our exploration and development, which we intend to fund through cash flows from operations and cash-in-hand, to be allocated approximately as follows:

• Colombia: US$85-95 million. Continue to develop and appraise the Tigana and Jacana oil fields and target new exploration prospects in the Llanos basin.
• Chile: US$17-20 million. Develop and explore oil and gas targets, both conventional and unconventional, in the Fell and Tierra del Fuego blocks.

• Brazil: US$3-4 million. Focus on exploration drilling in onshore blocks.

• Argentina: US$20-25 million. Focus on development and exploration oil and gas targets in the Neuquén Basin.

• Peru: US$95-105 million. Focus on construction of early production facilities in the Morona block with the goal of putting the Situche Central light oil field into production by 2020, subject to approval of the environmental impact assessment.

In addition, we have developed downside and upside work program scenarios based on different oil prices and project performance. The downside scenario work program considers a reference oil price assumption below US$65 per barrel and consists of an alternative capital expenditure program of approximately US$120 million-US$140 million consisting mainly of certain low risk and quick cash flow generating projects. The upside scenario work program considers a reference oil price assumption above US$75 per barrel or higher and consists of an alternative capital expenditure program of approximately US$240 million-US$270 million to be selected from identified projects designed to increase reserves and production.

## Our operations

We have a well-balanced portfolio of assets that includes working and/or



economic interests in 25 hydrocarbon blocks, 24 of which are onshore blocks, including 10 in production as of December 31, 2018, as well as in an additional shallow-offshore concession in Brazil that includes the Manati Field. In addition, we have one concession in Brazil, the PN-T-597 Block, that is subject to the entry into the concession agreement by the ANP and one concession in Argentina, the Parlamentos Block, that remains subject to regulatory approval as of the date of this annual report.

## Operations in Colombia

Our Colombian assets currently give us access to more than 244,900 gross exploratory and productive acres across 6 blocks in what we believe to be one of South America’s most attractive oil and gas geographies.

Since we entered Colombia in 2012, we have achieved consistent growth in our oil production and proved reserves in Colombia, mainly achieved through successful exploration and development activities we made at our operated Llanos 34 Block, which as of December 31, 2018 accounts for 95% of our production and 97% of our proved reserves in Colombia.

The table below shows average production and proved oil and gas reserves (derived from D&M Reserves Report) in Colombia for the years ended December 31, 2018, 2017 and 2016:

<table><tr><td></td><td>2018</td><td>2017</td><td>2016</td></tr><tr><td>Average net production (mboepd)</td><td>28.4</td><td>21.8</td><td>15.5</td></tr><tr><td>Net proved reserves at year-end (mmboe)</td><td>75.1</td><td>65.5</td><td>37.3</td></tr></table>

Highlights of the year ended December 31, 2018 related to our operations in Colombia included:

• Successful drilling campaign with 21 gross wells drilled and put into production in the Jacana and Tigana oil fields in the Llanos 34 Block. This campaign includes the successful drilling and testing of Tigana Norte 9 appraisal well;

• Discovery of the Chachalaca Sur oil field, following the successful drilling and testing of the Chachalaca Sur 1 exploration well, located on a fault trend to the west of the Tigana and Jacana oil fields;

• Discovery of the new Tigui oil field, following the successful drilling and testing of the Tigui 1 exploration well;

• Average net production increased by 30%, to 28.4 mboepd in 2018 from 21.8 mboepd in 2017;

• Proved oil and gas reserves increased by 15% to 75.1 mmboe at year-end 2018, from 65.5 mmboe at year-end 2017 after producing 9.4 mmboe;

• Maintenance of production and operating costs levels per barrel from US$5.6 in 2017 to US$5.5 in 2018;

• Flowline construction to connect the Llanos 34 block oil fields to regional pipeline infrastructure is on budget and on schedule and expected to be operational in 2019;
• In November 2018 we signed an agreement with Perenco Oil and Gas to divest the La Cuerva and Yamu blocks for $18 million plus a contingent payment of $2 million, based on future oil prices; and

• In November 2018 we acquired LGI's 20% equity interest in our Colombian subsidiary, which expanded our participation in the valuable Llanos 34 block.

Our interests in Colombia include working interests and economic interests. "Working interests" are direct participation interests granted to us pursuant to an E&P Contract with the ANH, whereas "economic interests" are indirect participation interests in the net revenues from a given block based on bilateral agreements with the concessionaires.

The map below shows the location of the blocks in Colombia in which we have working and/or economic interests.



(1) On November 2, 2018, GeoPark and Perenco Oil and Gas executed a purchase and sale agreement in which Perenco agreed to purchase GeoPark's 100% working interest in the La Cuerva and Yamu blocks. Closing of the transaction is subject to customary regulatory approvals. We will continue operating the blocks until the completion of the divestiture process. See "—Our operations—Operations in Colombia."

Eastern Llanos Basin: (Llanos 34, La Cuerva, Yamú, Llanos 32, Abanico, and VIM-3 Blocks)

The Eastern Llanos Basin is a Cenozoic Foreland basin in the eastern region of Colombia. Two giant fields (Caño Limón and Castilla), three major fields (Rubiales, Apiay and Tame Complex) and approximately fifty minor fields had been discovered. The source rock for the basin is located beneath the east flank of the Eastern Cordillera, as a mixed marine-continental shale basaltic facies of the Gachetá formation. The main reservoirs of the basin are represented by the Paleogene Carbonera and Mirador sandstones. Within the Cretaceous sequence, several sandstones are also considered to have good reservoirs.

Llanos 34 Block. We are the operator of, and have a 45% working interest in, the Llanos 34 Block, which covers approximately 82,200 gross acres (333 sq. km). We acquired an interest in and took operatorship of the block in the first quarter of 2012, which at that time had no production, reserves or wells drilled on it, and with 210 sq. km of existing 3D seismic data on which our team had mapped multiple exploration prospects. From 2012 to 2018 we engaged in exploration and development activities that resulted in multiple new oil fields discovered and increased production and proved reserves year by year. Average net production in 2018 was 27,219 bopd and net reserves of 72.5 mmboe. The remaining commitment amounts to US$1.9 million at our working interest.

Our partner in the Llanos 34 Block is Parex, which has a 55% interest. See “—Our operations.” We operate in the block pursuant to an E&P Contract with the ANH. See “—Significant Agreements—Colombia—E&P Contracts—Llanos 34 Block E&P Contract.”

La Cuerva Block. We are the operator of, and have a 100% working interest in, the La Cuerva Block, which covers approximately 24,500 gross acres (99.1 sq. km). Average net oil production in 2018 was 606 bopd. We operate in the block pursuant to an E&P Contract with the ANH. On November 2, 2018 we executed a Sale Purchase Agreement with Perenco to sale the 100% working interest in the La Cuerva Block. Closing of the transaction is subject to customary regulatory approvals, which are expected to occur during 2019.

Yamú Block. We are the operator of, and have a 100% working interest in, the Yamú Block, which covers approximately 5,588 gross acres (22.6 sq. km). For the year ended December 31, 2018, our average net production was 375 bopd. On November 2, 2018 we executed a Sale Purchase Agreement with Perenco to sale the 100% working interest in the Yamú Block. Closing of the transaction is subject to customary regulatory approvals, which are expected to occur during 2019.

Llanos 32 Block. We have a 12.5% working interest in the Llanos 32 Block, as a result of our acquisition of an additional 2.5% interest on August 22, 2017. The Llanos 32 Block covers approximately 57,000 gross acres (230.7 sq. km). Parex is the operator of this block and has a 87.5% working interest. Since 2015, the operator focused on the commissioning of a gas facility on this block to produce natural gas and light crude oil from the Une formation and



to facilitate shipment of processed gas south to the adjacent Llanos 34 Block. For the year ended December 31, 2018, our average net production in the Llanos 32 Block was 306 bopd. The remaining commitment related to this block is to drill one exploratory well before August 2018 was already fulfilled. On February 19, 2019 the parties to the Llanos 32 contract requested ANH to grant an extension of one year to phase 2 of the subsequent exploratory program in order to drill an exploratory well amounting to US$ 4.7 million gross subject to ANH approval. We executed an agreement with Parex by which we obtained a 25% working interest in the remaining exploration areas of the block.

VIM-3 Block. On July 23, 2014 we were awarded an exploratory license during the 2014 Colombia Bidding Round, carried out by the ANH. We are entitled to operate the block, in which we have a 100% working interest. The VIM-3 Block is located in the Lower Magdalena Basin. Our winning bid consisted of committing to a Royalty X Factor of 3% and a minimum investment program of 200 sq. km of 2D seismic data acquisition and drilling one exploratory well, with a total estimated investment of US$22.3 million during the initial exploratory period ending February 2019. On June 21, 2017, the ANH approved our relinquishment of 79.15% of the VIM 3 Block area. The remaining area covers 48,950 acres and the commitments described above are not affected. On September 12, 2018, the ANH accepted our proposal to extend the first exploratory phase for an additional period ending May 12, 2019. Additionally, we requested the ANH to terminate the E&P Contract due to environmental restrictions in the block. These restrictions became apparent once the National Authority of Environmental Licenses (ANLA) issued the environmental license. As of the date of this annual report, the termination request is under review and the remaining commitment amounts to US$22.3 million.

Abanico Block. In October 1996, Ecopetrol and Explotaciones CMS Nomeco Inc. entered into the Abanico Block association contract. Pacific Rubiales Energy is the operator of, and has a 100% working interest in, the Abanico Block, which covers an area of approximately 26,658 gross acres (103 sq. km). We do not maintain a direct working interest in the Abanico Block, but rather have a 10% economic interest in the net revenues from the block pursuant to a joint operating agreement initially entered into with Kappa Resources Colombia Limited (now Pacific, who subsequently assigned its participation interest to Cespa de Colombia S.A., who then assigned the interest to Explotaciones CMS Oil & Gas), Maral Finance Corporation and Getionar S.A.

## Operations in Chile

Our Chilean assets currently give us access to 808,000 of gross exploratory and productive acres across 5 blocks in a large fully-operated land base across the Magallanes Basin, with existing reserves, production and cash flows. Our Chilean blocks are located in the provinces of Ultima Esperanza, Magallanes and Tierra del Fuego in the Magallanes Basin, a proven oil and gas-producing area. As of December 31, 2018, the Magallanes Basin accounted for all of Chile's oil and gas production. Although this basin has been in production for over 60 years, we believe that it remains relatively underdeveloped.

Substantial technical data (seismic, geological, drilling and production information), developed by us and by ENAP, provides an informed base for new hydrocarbon exploration and development. Shut-in and abandoned fields may also have the potential to be put back in production by constructing new pipelines and plants. Our geophysical analyses suggest additional development potential in known fields and exploration potential in undrilled prospects and plays, including opportunities in the Springhill, Tertiary, Tobífera and Estratos con Favrela formations. The Springhill formation has historically been the source of production in the Fell Block, though the Estratos con Favrela shale formation is the principal source rock of the Magallanes Basin, and we believe it contains unconventional resource potential.

Highlights of the year ended December 31, 2018 related to our operations in Chile included:

• Discovery of the Jauke gas field with successful drilling and testing of the Jauke 1 exploration well in the Fell block;

• Discovery of the Uaken gas field with successful drilling and testing of the Uaken 1 exploration well in the Fell block;

• Average net oil and gas production declined to 2,722 boepd in 2018 from 2,885 boepd in 2017;

• Proved oil and gas reserves decreased by 9% to 6.8 mmboe at year-end 2018, from 7.5 mmboe at year-end 2017 after producing 0.9 mmboe;

• Capital expenditures decreased by 23% to US$7.9 million in 2018 from US$10.2 million in 2017; and

• In November 2018 we acquired LGI's 20% equity interest in our Chilean subsidiary.

## Fell Block

In 2006, we became the operator and 100% interest owner of the Fell Block. When we first acquired an interest in the Fell Block in 2002, it had no material oil and gas production. Since then, we have completed more than 1,100 sq. km of 3D seismic surveys and drilled 117 exploration and development wells. In the year ended December 31, 2018, we produced an average of 2,708 boepd, in the Fell Block, consisting of 29% oil.

The Fell Block has an area of approximately 368,000 gross acres (1,488 sq. km) and its center is located approximately 140 km northeast of the city of Punta Arenas. It is bordered on the north by the international border between Argentina and Chile and on the south by the Magellan Strait.

From 2006 through August 2011, we successfully explored and developed the Fell Block, which allowed us to transition approximately 84% of the Fell Block's area from an exploration phase into an exploitation phase, which we expect will last through 2032. During the exploration phase, we exceeded the minimum work and investment commitment required under the Fell Block CEOP by more than 75 times. There are no minimum work and investment commitments under the Fell Block CEOP associated with the exploitation phase.

The Fell Block is located in the north-eastern part of the Magallanes Basin. The principal producing reservoir is composed of sandstones in the Springhill formation, at depths of 2,200 to 3,500 meters. Additional reservoirs have been discovered and put into production in the Fell Block—namely, Tobífera formation volcanoclastic rocks at depths of 2,900 to 3,600 meters, and Upper Tertiary and Upper Cretaceous sandstones, at depths of 700 to 2,000 meters.

Our geosciences team identified and developed an attractive inventory of prospects and drilling opportunities for both exploration and development in the Fell Block.

During 2018, we successfully drilled and completed the Jauke X-1 exploration well. The well is in production, and the gas is being sold to Methanex through a long-term gas contract. In addition, we continued to focus on maintaining production levels, and reducing production, operating costs and workforce costs.

The Jauke gas field is part of the large Dicky geological structure in the Fell block and has the potential for multiple development drilling opportunities. Petrophysical analysis also indicates hydrocarbon potential in the shallower El Salto formation which will be tested in the future. Our 2019 work plan includes the drilling of an additional well.

The Fell Block also contains the Estratos con Favrella shale reservoir, which we believe represents a high-potential, unconventional resource play for shale oil, as a broad area within Fell Block (1,000 sq. km) which appears to be in the oil window for this play.
Tierra del Fuego Blocks (Isla Norte, Campanario and Flamenco Blocks)
In the first and second quarters of 2012, we entered into three CEOPs with ENAP and Chile granting us working interests in the Isla Norte, Campanario and Flamenco Blocks, located in the center-north of the Tierra del Fuego Province of Chile. We are the operator of all three of these blocks, with working interests of 60%, 50% and 50%, respectively. We believe that these three blocks, which collectively cover 347,700 gross acres (1,407 sq. km) and are geologically contiguous to the Fell Block, represent strategic acreage with resource potential. We have committed to paying 100% of the required minimum investment under the CEOPs covering these blocks, in an aggregate amount of US$101.4 million through the end of the first exploratory periods for these blocks, which includes our covering of ENAP's investment commitment corresponding to its working interest in the blocks.

Flamenco Block. We are the operator of, and have a 50% working interest in, the Flamenco Block, in partnership with ENAP. The block covers approximately 105,900 gross acres (428 sq. km). In June 2013, we discovered a new oil and gas field in the block following the successful testing of the Chercán 1 well, the first well drilled by us in Tierra del Fuego. As of March 31, 2019, we had completed 100% of the committed 570 sq. km of 3D seismic surveys and the drilling activities for the first exploration period under the CEOP governing the Flamenco Block. In the year ended December 31, 2018, we produced an average of 14 boepd in the Flamenco Block.

On June 30, 2017, the Chilean Ministry accepted our proposal to extend the second exploratory period for an additional period of 18 months. As of the date of this annual report, US$2.1 million investment commitments related to this block (corresponding to one exploratory well) remain outstanding and will be entirely assumed by us. On December 20, 2018, we proposed to extend the second exploratory period for an additional period of 18 months, ending November 7, 2020. As of the date of this annual report the Chilean Ministry has not replied.

Isla Norte Block. We are the operator of and have a 60% working interest in partnership with ENAP in the Isla Norte Block, which covers approximately 97,650 gross acres (395 sq. km). As of March 31, 2019, we had completed 100% of the committed 350 sq. km of 3D seismic surveys and drilled one exploratory well, which represents the first oil discovery within the block. As of the date of this annual report, outstanding investment commitments of US$2.9 million related to this block correspond to two exploratory wells to be executed before May 7, 2019.

Campanario Block. We are the operator of, and have a 50% working interest in, the Campanario Block, in partnership with ENAP. The block covers approximately 144,150 gross acres (583 sq. km). As of March 31, 2019, we had completed 100% of the committed 578 sq. km of 3D seismic surveys and have also drilled five exploratory wells, including the Primavera Sur 1 well that marks the first discovery of an oil field on the Campanario Block in addition to one development well. As of the date of this annual report, outstanding



investment commitments of US$4.8 million related to this block correspond to three exploratory wells to be executed before July 10, 2019.

Tranquilo Block. We completed a seismic program consisting of 163 sq. km of 3D seismic and 371 sq. km of 2D seismic survey work, and drilled four wells, including the Palos Quemados and Marcou Sur well. We discovered gas in the El Salto formation of the Palos Quemado well. At the Palos Quemados well, we completed a 22-week commercial feasibility test aimed at defining its productive potential. As the test was not conclusive, we were granted permission by the Chilean Ministry of Energy to extend the testing period for an additional six months. Upon such testing period, we kept 4 provisional protection areas, which enabled continued analysis of the area prior the declaration of its commercial viability for a period of 5 years. On January 17, 2013, we formally announced to the Chilean Ministry of Energy our decision not to proceed with the second exploratory period and to terminate the exploratory phase of the Tranquilo Block CEOP. Subsequently, we relinquished all areas of the Tranquilo Block, except for a remaining area of 92,417 gross acres, for the exploitation of the Renoval, Marcou Sur, Estancia Maria Antonieta and Palos Quemados Fields, which we have identified as the areas with the most potential for prospects in the block. In November 2017, we proposed to the Ministry of Energy to extend the period to declare the commerciality of discoveries in the areas of Palos Quemados, Maria Antonieta and Marcou Sur for an additional period of 24 months. In February 2018, the Ministry approved our proposal. In December 2018, we increased our working interest to 100%. The approval of the agreement with Pluspetrol in connection with this change is still under review by the Ministry of Energy.

## Operations in Brazil

Our Brazilian assets currently give us access to 68,600 of gross exploratory and productive acres across 7 blocks (6 exploratory blocks and the BCAM-40 Concession, which is in production phase) in an attractive oil and gas geography.

Highlights of the year ended December 31, 2018 related to our operations in Brazil included:

• Average net oil and gas production of 2,925 boepd (99% gas) in the year ended December 31, 2018, as compared to 2,910 boepd in 2017;

• Capital expenditures decreased by 36% to US$2.3 million in 2018 from US$3.6 million in 2017; and

• Praia dos Castelhanos 1 exploration well was drilled in the REC-T-128 block to a total depth of 8,431 feet and will be completed and tested in the first half of 2019.
The map below shows the location of our concessions in Brazil in which we have a current or future working interest, including the BCAM-40 Concession and the concessions from bidding rounds 11, 12, 13 and 14.

## Manati Field

As a result of the Rio das Contas acquisition, we have a 10% working interest in the BCAM-40 Concession, which originally included interests in the Manati Field and the Camarao Norte Field, and which is located in the Camamu-Almada Basin. Petrobras is the operator of, and has a 35% working interest in, the BCAM-40 Concession, which covers approximately 22,784 gross acres (92.2 sq. km). In addition to us, Petrobras' partners in the block are Brasoil and Enauta Energia S.A. (Enauta), with 10% and 45% working interests, respectively. Petrobras operates the BCAM-40 Concession pursuant to a concession agreement with the ANP, executed on August 6, 1998. See "—Significant Agreements—Brazil—Overview of concession agreements—BCAM-40 Concession Agreement." In September 2009, Petrobras announced the relinquishment of BCAM-40's exploration area within the concession to the ANP, except for the Manati Field and the Camarao Norte Field. In August 2018, Petrobras announced the relinquishment of the Camarao Norte Field.

The Manati Field is located 65 km south of Salvador, offshore at a water depth of 35 meters. The field was discovered in October 2000, and, in 2002, Petrobras declared the field commercially viable. Production began in January 2007. As of December 31, 2018, 11 wells had been drilled in the Manati Field, 6 of which are productive and connected to a fixed production platform installed at a depth of 35 meters, located 9 km from the coast of the State of Bahia. From the platform, the gas flows by sea and land through a 125 km pipeline to the Estação Vandemir Ferreira or EVF gas treatment plant. The gas is sold to Petrobras up to a maximum volume as determined in the existing Petrobras Gas Sales Agreement (as defined below). In July 2015, we signed an amendment to the existing Gas Sales Agreement with Petrobras that covers 100% of the remaining gas reserves of the Manati Field.

Also, in 2015, in order to improve the field gas recovery and production, Manati's consortium built an onshore compression plant that started operating in August 2015. The compression plant involved capital expenditures of approximately US$3.7 million at our working interest and allowed us to classify all existing proved undeveloped reserves as proved developed.



Some environmental licenses related to operation of the Manati Field production system and natural gas pipeline are expired. However, the operator submitted, in a timely manner, the request for renewal of those licenses and as such this operation is not in default as long as the regulator does not state its final position on the renewal.

## Round 11 Concessions

During ANP’s 11th Bid Round, held in May 2013, we were awarded 7 exploratory blocks, of which 2 were in the Reconcavo Basin in the state of Bahia and 5 were in the Potiguar Basin in the state of Rio Grande do Norte. The exploratory phase for these concessions is divided into two exploratory periods, the first of which lasts for three years and the second of which is non-obligatory and can last for up to two years.

In 2016, after fulfilling the committed exploratory commitments and further reevaluation of commercial potential, five exploratory blocks were relinquished to the ANP (RECT 85, POT T 620, POT T 663, POT T 664 and POT T 665).

## REC-T 94 Concession

In the REC-T 94 we committed R$17.6 million (approximately US$ 4.5 million, at the December 31, 2018 exchange rate of R$3.9 to US$1.00) during the first exploratory period consisting of drilling two exploratory wells and 31 sq. km of 3D seismic surveys.

During the year 2014 we executed a 3D seismic survey. Seismic data interpretation in 2015 and 2016 defined two well locations, one of which was drilled in 2017. The estimated remaining commitment amounts to US$0.9 million.

## POT-T 619 Concession

In the POT-T 619 Concession we committed investments of R$2.3 million (approximately US$0.6 million at the December 31, 2018 exchange rate of R$3.9 to US$1.00) during the first exploratory period, equivalent to 46 km of 2D seismic work.

During the year 2014 we executed a 2D seismic survey. Seismic data processing was concluded in 2015. After seismic interpretation, we decided to continue to the second exploratory period in September 2016, which lasts for two years with a commitment to drill one exploratory well. The well was drilled during 2018 and was abandoned. There is no pending commitment.

## Round 12 Concessions

In November 2013, in the 12th Bid Round, the ANP awarded us two concessions (the PN-T-597 Concession in the Parnaíba Basin in the State of Maranhão and the SEAL-T-268 Concession in the Sergipe Alagoas Basin) in the State of Alagoas.

For more information, see “Item 3. Key information—D. Risk factors—Risks relating to our business—The PN-T-597 Concession Agreement in Brazil may not close.”

The Parnaíba Basin, which covers an area of approximately 148 million gross acres (600,000 sq. km), is a basin with large underexplored areas. As of December 31, 2018, the basin had two fields in production in the basin.

In the PN-T-597 Concession we committed R$7.7 million (approximately US$2.0 million, at the December 31, 2018 exchange rate of R$3.9 to US$1.00) for the first exploratory period, equivalent to 180 km of 2D seismic.

The exploratory phase for this concession is divided into two exploratory periods. Given that Parnaíba Basin is considered as a “new frontier” area by the ANP, the first exploratory period lasts four years, and the second exploratory period, which is optional, can last for up to two years.

See “Item 3. Key Information—D. Risk factors—Risks relating to our business—The PN-T-597 may not close” and “—D. Risk factors—Risks relating to the countries in which we operate—Our operations may be adversely affected by political and economic circumstances in the countries in which we operate and in which we may operate in the future” for more information.

## SEAL-T-268 Concession

In the SEAL-T-268 Concession we committed R$1.6 million (approximately US$0.4 million, at the December 31, 2018 exchange rate of R$3.9 to US$1.00) for the first exploratory period. The exploratory phase for this concession is divided into two exploratory periods, the first lasting three years, and the second, which is optional, can last for up to two years. During 2016, an electromagnetic survey acquisition of 70 stations and reprocessing of 58 km of vintage 2D seismic was performed and, after ANP approval of the extension of the first exploratory phase, we will fulfill part of the remaining committed work program that amounts to US$ 0.2 million.

## Round 13 Concessions

During ANP’s 13th Bid Round held in October 2015, we were awarded four exploratory concessions, of which two were in the Potiguar Basin in the state of Rio Grande do Norte and two were in the Reconcavo Basin in the state of Bahia. The exploratory phase for these concessions is divided into two exploratory periods, the first of which lasts for three years and the second of which is non-obligatory and can last for up to two years.

## POT-T-747 and POT-T-882

The POT-T-747 and POT-T-882 blocks are located in the Potiguar Basin and encompass an area of 14,829 acres (60 square km). Total commitment to the ANP was R$8.5 million (approximately US$2.2 million, at the December 31, 2018 exchange rate of R$3.9 to US$1.00) during the first exploratory period and is equivalent to acquiring 70 km of 2D seismic and drilling one well. During 2017 3D seismic was reprocessed and a well was drilled in the



POT-T-747 block during 2018 and was abandoned. All the commitments related to POT-T-882 were fulfilled as of the date of this annual report. The estimated remaining commitment in the POT-T-747 block amounts to US$0.5 million.

## REC-T-128 and REC-T-93

Both blocks are part of the Reconcavo Basin and have a combined area of 15,405 acres (62.3 square km). The block REC-T-128 was bid for in partnership with Geosol with a 70% working interest for us and 30% working interest for Geosol. The total commitment to the ANP was R$10.7 million (approximately US$2.7 million at the December 31, 2018 exchange rate of R$3.9 to US$1.00) during the first exploratory period and consists of acquiring 9 km2 of 3D seismic, drilling one well and performing geochemical analysis at two geological levels.

During 2016, regional interpretation studies were performed in the area. Part of the minimum exploratory program of Block REC-T-93 has been fulfilled and approved by ANP with the 3D regional seismic acquisition, which also covered Block REC T 94 (Round 11). During 2018, 3D reprocessing was performed in the REC-T-128 block and we also drilled the Praia dos Castelhanos 1 exploration well that will be completed and tested in the first half of 2019. As of December 31, 2018, the estimated remaining commitment in the REC-T-128 block amounts to US$2.2 million. This commitment was fulfilled in the first quarter of 2019.

Upon complete fulfillment of the minimum exploratory work program and the accomplishment of local content commitments, the POT-T-882 and REC-T-93 blocks were relinquished to the ANP in December 2018.

## Round 14 Concessions

During ANP’s 14th Bid Round held in September 2017, we were awarded one exploratory concession, in the Potiguar Basin in the state of Rio Grande do Norte.

## POT-T-785

The POT-T-785 block covers an area of 7,875 acres in the Potiguar Basin, surrounded by producing fields operated by Petrobras. Total commitment to the ANP was R$1.2 million (US$0.3 million, at the December 31, 2018 exchange rate of R$3.9 to US$1.00) during the first exploratory period and is equivalent to acquiring 4 km2 of 3D seismic and performing geochemical analysis before January 29, 2023. As of December 31, 2018, the estimated remaining commitment in the POT-T-785 block amounts to US$0.1 million.

## Operations in Peru

In October 2014, we entered into an agreement to expand our footprint into Peru (our fifth country platform in Latin America) through the acquisition of Morona Block in a joint venture with Petroperu.
The Morona Block has DeGolyer and MacNaughton certified net proved reserves of 18.5 mmboe as of December 31, 2018, composed of 100% oil.

The map below shows the location of the Morona Block in Peru.






The table below summarizes information about the block in Peru.

<table><tr><td>Block</td><td>Gross acres (thousand acres)</td><td>Working interest \( ^{(1)} \)</td><td>Operator</td><td>Net proved reserves (mmboe)</td><td>Production (boepd)</td><td>Basin</td><td>Expiration concession year</td></tr><tr><td>Morona</td><td>1,881</td><td>75%</td><td>GeoPark</td><td>18.5</td><td>—</td><td>Marañon</td><td>Exploitation: 2039 \( ^{(2)} \)</td></tr></table>

(1) Corresponds to the initial working interest. Petroperu will have the right to increase its working interest in the block by up to 50%, subject to the recovery of our investments in the block through agreed terms in the Petroperu SPA. See "Item 4. Information on the Company—B. Business Overview—Our operations—Operations in Peru—Morona Block."

(2) The concession will expire twenty (20) years after EIA approval.

## Morona Block

The Morona Block covers an area of approximately 1,881 thousand gross acres (7,600 sq. km). More than 1 billion barrels of oil have been produced from the surrounding blocks in the Marañon Basin.

On October 1, 2014, we entered into an agreement to acquire a 75% working interest in the Morona Block in Northern Peru. As stated above, this agreement includes a work program to be executed by us. This program includes 3 phases, and we may decide whether to continue or not at the end of each phase. On December 1, 2016, through Supreme Decree N° 031-2016-MEN, the Peruvian government approved the amendment to the License Contract of Morona Block appointing GeoPark as operator and holder of 75% of the License-Contract.

The Morona Block contains the Situche Central oil field, which has been delineated by two wells (with short term tests of approximately 2,400 and 5,200 bopd of 35-36° API oil each) and by 3D seismic. In addition to the Situche Central field, the Morona Block has a large exploration potential with several high impact prospects and plays. The Morona Block includes geophysical surveys of 2,783 km (2D seismic) and 465 sq. km (3D seismic), and an operating field camp and logistics infrastructure. The area has undergone oil and gas exploration activities for the past 40 years, and there exist ongoing association agreements and cooperation projects with the local communities. The expected work program and development plan for the Situche Central oil field is to be completed in three stages.

The goal of the initial two stages is to start production from the two wells already drilled in the field, in order to determine the most effective overall development plan and to begin to generate cash flow. These initial stages require an investment of approximately US$100 million to US$150 million and are expected to be completed in 2020. We have committed to carry Petroperu, by paying its portion of the required investment in these initial phases. In addition, we are required to cover any capital or operational expenditures of Petroperu associated with the project until December 31, 2020. We expect these expenditures to be substantially reimbursed by Petroperu from revenues associated to future sales. The beginning of such activities is subject to the approval of an environmental impact assessment by the Peruvian environmental authority.

In accordance with the agreement between us and Petroperu, commitments assumed by GeoPark are subject to certain economical and technical conditions being met.

The third stage, which will be initiated once production has been established, is expected to focus on carrying out the full development of the Situche Central field, including transportation infrastructure.

The exploratory program entails drilling one exploratory well. Exploratory program capital expenditures will be borne exclusively by us. Expected capital expenditures in 2019 for the Morona Block are mainly related to flexible pipeline installation, temporary access road, location conditioning and the Morona Camp dock revamping. These activities are subject to the approval of the Environmental Impact Study, which is under review by the local authority as of the date of this annual report. The approval of the Development Environmental Impact Study is expected by the end of the second quarter of 2019.

Initially we will hold a 75% working interest in the block. However, according to the terms of the agreement, Petroperu has the right to increase its working interest in the block up to 50%, subject to the recovery of our investments in the block by certain agreed factors.

See "Item 3. Key Information—D. Risk factors—Risks relating to our business—Our inability to access needed equipment and infrastructure in a timely manner may hinder our access to oil and natural gas markets and generate significant incremental costs or delays in our oil and natural gas production" and "—We may suffer delays or incremental costs due to difficulties in negotiations with landowners and local communities, including native communities, where our reserves are located."



## Operations in Argentina

(1) Working interest corresponds to the working interests held by our respective subsidiaries in such block, net of any working interests held by other parties in each block.



Highlights of the year ended December 31, 2018 related to our operations in Argentina included:

• Operational takeover of newly acquired Aguada Baguales, El Porvenir and Puesto Touquet Blocks in the Neuquén Basin with an average net oil and gas production of 1,835 boepd in 2018;

• Capital expenditures of US$9.0 million in 2018;

• Proved oil and gas reserves of 5.0 mmboe at year-end 2018; and

• Acquired new low-cost large exploration acreage, the Los Parlamentos block in the Neuquén Basin, in partnership with YPF S.A. (“YPF”)

## Neuquén blocks

On March 27, 2018, we acquired a 100% working interest and operatorship of the Aguada Baguales, El Porvenir and Puesto Touquet Blocks, which are located in the Neuquén Basin, for a total consideration of US$52 million, less a working capital adjustment of US$ 3.1 million. The blocks include production facilities, such as hydrocarbons treatment, storage, and delivery infrastructure.

## Los Parlamentos Block Farm-in Agreement

In June 2018, we acquired a 50% working interest in the Los Parlamentos exploratory block in partnership with YPF, the largest oil and gas producer in Argentina. In accordance with the partnership agreement, YPF assumed the operationship of the block and GeoPark assumed a commitment to fund its 50% working interest of one exploratory well and additional 3D seismic, which amounts to US$6 million at GeoPark's working interest, over the next three years.

## 2014 Mendoza Bidding Round

On August 20, 2014, the consortium of Pluspetrol and us was awarded two exploration licenses in the Sierra del Nevado and Puelen Blocks, as part of the 2014 Mendoza Bidding Round in Argentina, carried out by Empresa Mendocina de Energía S.A. (“EMESA”).

The consortium consists of Pluspetrol (operator with a 72% working interest), EMESA (non-operator with a 10% working interest) and us (non-operator with an 18% working interest). In accordance with the terms of the bidding, all of the expenditures related to EMESA's working interest will be carried by Pluspetrol and us proportionately to our respective working interests and will be recovered through EMESA's participation in future potential production.

We have committed to a minimum aggregate investment of US$6.2 million for our working interest, which includes the work program commitment on both blocks during the first three years of the exploratory period. As of December 31, 2018, the remaining commitments in the Sierra del Nevado block for the first exploratory period amount to between US$0.5 and US$1.0 million at our working interest. There is no pending commitment in the Puelen block.

## CN-V Block Farm-in Agreement

On July 22, 2015, we signed a farm-in agreement with Wintershall for the CN-V Block in Argentina, which complements our existing acreage in the basin. Wintershall is Germany’s largest oil and gas producer and a subsidiary of BASF Group. Under the agreement, we committed to operate during the exploratory phase and receive a 50% working interest in the CN-V Block in exchange for having to drill and fully fund two exploratory wells for a total of US$10 million.

The CN-V Block covers an area of approximately 57.2 thousand gross acres and is located in the Neuquén Basin in southern Argentina. The block has 3D seismic coverage of 180 sq. km and is adjacent to the producing Loma Alta Sur oil field, a region and play-type well known to our team. The block includes upside potential in the developing Vaca Muerta unconventional play.

During 2017, we drilled the first exploratory well, Rio Grande Oeste 1, which resulted in the discovery of Rio Grande Oeste oil field. During 2018, we drilled the second exploratory well, Rio Grande Este 1, which is under evaluation. With these investments GeoPark Argentina has fulfilled the initial commitment of US$10 million and the operation of the block was transferred to Wintershall. As of the date of this annual report, the estimated remaining commitment in the CN-V block for the current exploratory period denominated “Field under evaluation”, ending on November 27, 2021, amounts to US$1.3 million at our working interest.

## Oil and natural gas reserves and production

## Overview

We have achieved consistent growth in oil and gas reserves from our investment activities since 2006, when we began production in the Fell Block in Chile, followed by successful acquisition, exploration and development activities in other countries in which we have a presence, including Colombia, Brazil, Argentina, and Peru.

## Our reserves

The following table sets forth our oil and natural gas net proved reserves as of December 31, 2018, which is based on the D&M Reserves Report.



<table><tr><td colspan="5">Net proved reserves</td></tr><tr><td>As of December 31, 2018</td><td></td><td>Natural gas (bcf)</td><td>Total net proved reserves (mmboe) \( ^{(1)} \)</td><td>% Oil</td></tr><tr><td colspan="5">Net proved developed</td></tr><tr><td>Colombia</td><td>32.3</td><td>1.8</td><td>32.6</td><td>99%</td></tr><tr><td>Chile</td><td>0.7</td><td>12.0</td><td>2.7</td><td>26%</td></tr><tr><td>Argentina</td><td>2.0</td><td>6.2</td><td>3.1</td><td>65%</td></tr><tr><td>Brazil</td><td>0.1</td><td>17.3</td><td>3.0</td><td>3%</td></tr><tr><td>Total net proved developed</td><td>35.1</td><td>37.3</td><td>41.4</td><td>85%</td></tr><tr><td colspan="5">Net proved undeveloped</td></tr><tr><td>Colombia</td><td>42.5</td><td>0.3</td><td>42.5</td><td>100%</td></tr><tr><td>Chile</td><td>2.6</td><td>8.8</td><td>4.1</td><td>63%</td></tr><tr><td>Argentina</td><td>1.4</td><td>3.2</td><td>1.9</td><td>74%</td></tr><tr><td>Peru</td><td>18.5</td><td>-</td><td>18.5</td><td>100%</td></tr><tr><td>Total net proved undeveloped  \( {}^{(2)} \)</td><td>65.0</td><td>12.3</td><td>67.0</td><td>97%</td></tr><tr><td colspan="5">Total net proved (Colombia, Chile, Peru, Argentina and Brazil)</td></tr></table>

 \( ^{(1)} \) We calculate one barrel of oil equivalent as six mcf of natural gas.

 \( ^{(2)} \) We plan to put 100% of our reported 2018 year-end proved undeveloped reserves into production through activities to be implemented within five years of initial disclosure.

We had net proved reserves of 108.4 mmboe at December 31, 2018, compared to net proved reserves of 95.7 mmboe as of December 31, 2017.

The 13.3% increase in net proved reserves in 2018, not including annual production, is mainly attributable to:

- Better than expected performance from existing wells from the Tigana and Jacana fields in the Llanos 34 Block, which added 15.4 mmboe.

• Extensions and discoveries that resulted in an increase of 9.9 mmboe due to the Tigana and Jacana appraisal wells and the Tigui oil field discovery in Llanos 34 Block, the Jauke gas field discovery in the Fell Block and the gas discovery of the Une Formation in the Llanos 32 Block.

• An increase of 5.7 mmboe resulting from the purchase of minerals related to the acquisitions of the Aguada Baguales, El Porvenir and Puesto Touquet blocks.

• An increase of 2.5 mmboe due to higher average oil and gas prices. This was partially offset by:

• Changes in a previously adopted development plan for the Max, Tua, Chachalaca Sur, Tilo, and Jacamar fields in the Llanos 34 Block, resulting in a 6.6 mmboe decrease.

• Lower than expected performance from existing wells in the Fell and Manati Blocks, resulting in a 1.0 mmboe decrease.

• Revisions in Peru that resulted in a 1.3 mmbbl decrease.
During the year ended December 31, 2018, we had 12.8 mmboe of our proved undeveloped reserves from December 31, 2017 converted to proved developed reserves due to development drilling in the Jacana and Tigana oil fields in the Llanos 34 Block. For further information relating to the reconciliation of our net proved reserves for the years ended December 31, 2018, 2017 and 2016, please see Table 5 included in Note 37 (unaudited) to our Consolidated Financial Statements.

## Internal controls over reserves estimation process

We maintain an internal staff of petroleum engineers and geosciences professionals who work closely with our independent reserves engineers to ensure the integrity, accuracy and timeliness of data furnished to our independent reserves engineers in their estimation process and who have knowledge of the specific properties under evaluation. Our Director of Exploration, Salvador Minniti, is primarily responsible for overseeing the preparation of our reserves estimates and for the internal control over our reserves estimation. He has more than 35 years of industry experience as an E&P geologist, with broad experience in reserves assessment, field development, exploration portfolio generation and management and acquisition and divestiture opportunities evaluation. See “Item 6. Directors, Senior Management and Employees—A. Directors and senior management.”

In order to ensure the quality and consistency of our reserves estimates and reserves disclosures, we maintain and comply with a reserves process that satisfies the following key control objectives:

• estimates are prepared using generally accepted practices and methodologies;

• estimates are prepared objectively and free of bias;

• estimates and changes therein are prepared on a timely basis;

• estimates and changes therein are properly supported and approved; and

• estimates and related disclosures are prepared in accordance with regulatory requirements.

Throughout each fiscal year, our technical team meets with Independent Qualified Reserves Engineers, who are provided with full access to complete and accurate information pertaining to the properties to be evaluated and all applicable personnel. This independent assessment of the internally-generated reserves estimates is beneficial in ensuring that interpretations and judgments are reasonable and that the estimates are free of preparer and management bias.

Recognizing that reserves estimates are based on interpretations and judgments, differences between the proved reserves estimates prepared by us and those prepared by an Independent Qualified Reserves Engineer of 10% or less, in aggregate, are considered to be within the range of reasonable differences. Differences greater than 10% must be resolved in the technical meetings. Once differences are resolved, the independent Qualified Reserves Engineer sends a preliminary copy of the reserves report to be reviewed by



the Technical Committee and Directors of each country. A final copy of the Reserves Report is sent by the Independent Qualified Reserve Engineer to be approved and signed by the Technical Committee and our CEO and CFO. See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees of our board of directors."

## Independent reserves engineers

Reserves estimates as of December 31, 2018 for Colombia, Chile, Brazil, Argentina and Peru included elsewhere in this annual report are based on the D&M Reserves Report, dated February 4, 2019 and effective as of December 31, 2018. The D&M Reserves Report, a copy of which has been filed as an exhibit to this annual report, was prepared in accordance with SEC rules, regulations, definitions and guidelines at our request in order to estimate reserves and for the areas and period indicated therein.

DeGolyer and MacNaughton, a Delaware corporation with offices in Dallas, Houston, Moscow, Algiers, Astana and Buenos Aires has been providing consulting services to the oil and gas industry since 1936. The firm has more than 200 professionals, including engineers, geologists, geophysicists, petrophysicists and economists that are engaged in the appraisal of oil and gas properties, the evaluation of hydrocarbon and other mineral prospects, basin evaluations, comprehensive field studies and equity studies related to the domestic and international energy industry. DeGolyer and MacNaughton restricts its activities exclusively to consultation and does not accept contingency fees, nor does it own operating interests in any oil, gas or mineral properties, or securities or notes of its clients. The firm subscribes to a code of professional conduct, and its employees actively support their related technical and professional societies. The firm is a Texas Registered Engineering Firm.

The D&M Reserves Report covered 100% of our total reserves. In connection with the preparation of the D&M Reserves Report, DeGolyer and MacNaughton prepared its own estimates of our proved reserves. In the process of the reserves evaluation, DeGolyer and MacNaughton did not independently verify the accuracy and completeness of information and data furnished by us with respect to ownership interests, oil and gas production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the fields and sales of production. However, if in the course of the examination something came to the attention of DeGolyer and MacNaughton that brought into question the validity or sufficiency of any such information or data, DeGolyer and MacNaughton did not rely on such information or data until it had satisfactorily resolved its questions relating thereto or had independently verified such information or data. DeGolyer and MacNaughton independently prepared reserves estimates to conform to the guidelines of the SEC, including the criteria of “reasonable certainty,” as it pertains to expectations about the recoverability of reserves in future years, under existing economic and operating conditions, consistent with the definition in Rule 4-10(a)(2) of Regulation S-X. DeGolyer and MacNaughton issued the D&M Reserves Report based upon its evaluation. D&M’s primary economic assumptions in estimates included oil and gas sales prices determined according to SEC guidelines, future expenditures and other economic assumptions (including interests, royalties and taxes) as provided by us. The assumptions, data, methods and procedures used, including the percentage of our total reserves reviewed in connection with the preparation of the D&M Reserves Report were appropriate for the purpose served by such report, and DeGolyer and MacNaughton used all methods and procedures as it considered necessary under the circumstances to prepare such reports.

However, uncertainties are inherent in estimating quantities of reserves, including many factors beyond our and our independent reserves engineers' control. Reserves engineering is a subjective process of estimating subsurface accumulations of oil and natural gas that cannot be measured in an exact manner, and the accuracy of any reserves estimate is a function of the quality of available data and its interpretation. As a result, estimates by different engineers often vary, sometimes significantly. In addition, physical factors such as the results of drilling, testing and production subsequent to the date of an estimate, economic factors such as changes in product prices or development and production expenses, and regulatory factors, such as royalties, development and environmental permitting and concession terms, may require revision of such estimates. Our operations may also be affected by unanticipated changes in regulations concerning the oil and gas industry in the countries in which we operate, which may impact our ability to recover the estimated reserves. Accordingly, oil and natural gas quantities ultimately recovered will vary from reserves estimates.

## Technology used in reserves estimation

According to SEC guidelines, proved reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with “reasonable certainty” to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation.

The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. The term “reasonable certainty” implies a high degree of confidence that the quantities of oil and/or natural gas actually recovered will equal or exceed the estimate. Reasonable certainty can be established using techniques that have been proved effective by actual production from projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes reasonable certainty. Reliable technology is a grouping of one or more technologies (including computational methods) that have been field tested and have been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation.



There are various generally accepted methodologies for estimating reserves including volumetric, decline analysis, material balance, simulation models and analogies. Estimates may be prepared using either deterministic (single estimate) or probabilistic (range of possible outcomes and probability of occurrence) methods. The particular method chosen should be based on the evaluator's professional judgment as being the most appropriate, given the geological nature of the property, the extent of its operating history and the quality of available information. It may be appropriate to employ several methods in reaching an estimate for the property.

Estimates must be prepared using all available information (open and cased hole logs, core analyses, geologic maps, seismic interpretation, production/injection data and pressure test analysis). Supporting data, such as working interest, royalties and operating costs, must be maintained and updated when such information materially changes.

## Proved undeveloped reserves

As of December 31, 2018, we had 67.0 mmboe in proved undeveloped reserves, an increase of 8.1 mmboe, or 14%, over our December 31, 2017 proved undeveloped reserves of 58.9 mmboe. Changes for the year ended December 31 2018, include (i) an increase of 8.9 mmboe in Colombia due to the Tigana and Jacana appraisal wells, the Tigui field discovery in the Llanos 34 Block and the gas discovery of the Une Formation in the Llanos 32 Block; (ii) an increase of 2.0 mmboe in Argentina due to the purchase of minerals in place related with the Aguada Baguales, El Porvenir and Puesto Touquet fields acquisitions during 2018; (iii) a decrease of 12.8 mmboe in Colombia due to the conversion of proved undeveloped reserves to proved developed reserves in the Llanos 34 Block; (iv) an increase of 8.2 mmboe in Peru due to revisions in the Morona Block; (v) an increase in Peru of 1.0 mmboe due to the impact of higher average oil prices in the Morona Block (vi) an increase of 8.2 mmboe due to the better than expected performance from existing wells from the Tigana and Jacana fields in the Llanos 34 Block in Colombia partially offset by a removal of 1.4 mmboe of proved undeveloped reserves related to a worse than expected performance in the Fell Block in Chile; (vii) an increase of 0.2 mmboe in Chile due to the Jauke field discovery in the Fell Block and (viii) a decrease in reserves of 6.3 mmboe in Colombia due to changes in a previously adopted development plan in Max, Tua, Chachalaca Sur, Tilo and Jacamar fields in the Llanos 34 Block.

Of our 67.0 mmboe of net proved undeveloped reserves, 42.5 mmboe (63%), 4.1 mmboe (6%), 1.9 mmboe (3%) and 18.5 mmboe (28%) were located in Colombia, Chile, Argentina and Peru, respectively.

During 2018, we incurred approximately US37.8 million in capital expenditures in Colombia to convert such proved undeveloped reserves to proved developed reserves.

No net proved undeveloped reserves were located in Brazil as of December 31, 2018.
The following table shows the evolution of total net proved undeveloped ("PUD") reserves in the year ended December 31, 2018.

 \( ^{(1)} \) Developed acreage is defined as acreage assignable to productive wells. Undeveloped acreage is defined as acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil or gas regardless of whether such acreage contains proved reserves. Net acreage based on our working interest.

## Productive wells

The following table sets forth our total gross and net productive wells as of February 28, 2019. Productive wells consist of producing wells and wells capable of producing, including natural gas wells awaiting pipeline connections to commence deliveries and oil wells awaiting connection to production facilities. Gross wells are the total number of producing wells in which we have an interest, and net wells are the sum of our fractional working interests owned in gross wells.

 \( ^{(1)} \) Includes wells drilled by other operators, prior to our commencing operations, and wells drilled in blocks in which we are not the operator. A productive well is an exploratory, development, or extension well that is not a dry well.

## Present activities

Our average oil and gas production in the first quarter of 2019 was 39,558 mboepd, with oil production of 34,358 mbopd and gas production of 5,200 mboepd. Of this total production, 81%, 7%, 6% and 6% were in Colombia, Chile, Argentina and Brazil, respectively.

In March 2019, we announced the entry into Ecuador through the acquisition of the Espejo and Perico exploratory blocks in the Intracapos Bid Round in the Oriente Basin located in the north-eastern part of Ecuador. The blocks were awarded to the GeoPark and Frontera consortium (50% GeoPark, 50% Frontera) in the form of production sharing contracts. The final award is contingent upon regulatory approvals and the execution of the contracts is expected for the second quarter of 2019.

On April 1, 2019, we secured 4,000 bopd through a zero-premium three-way structure, with a minimum average price of US$45-US$55 per barrel and a maximum average price of US$79 per barrel, for the period commencing April 2019 to March 2020.

## Marketing and delivery commitments

## Colombia

Our production in Colombia consists primarily of crude oil. Sales for the year ended December 31, 2018 were made under a long term sales agreement with Trafigura.

During 2018, our oil sales were done at wellhead with the delivery point at the truck-loading station at each field. In Colombia, pipelines have minimum quality conditions for access to the system. Consequently, and because we are mid to heavy oil producers, loading to the pipeline system requires the use of diluents which are blended into our crude. Under the Trafigura Agreement, we followed agreed priorities for the volumes to be transported through the ODL Pipeline. For the period from January 1, 2018 to December 31, 2018, Trafigura bought 100% of our production. In 2018, we amended the Trafigura Agreement to include a fixed volume oil sale of 8,000 bopd to Trafigura from January to December 2019.

Our oil sales price formula is based on market reference indices (Brent price and Vasconia differential) and discounts that consider transportation costs and quality adjustments.

With the expiration of the obligation to sell all of our Colombian production to Trafigura, we have started diversifying our client base in Colombia, allocating sales on a competitive basis to leading industry participants, including traders and other producers.

Our sales strategy is aimed at securing the highest available pricing for our production while securing a reliable and safe execution. To that end, we focus on developing synergies and strategic partnerships with both clients and the national transport systems, in order to obtain a reduction in costs and increased revenues by making use of the best alternatives available. Such is the case of the implementation of an unloading facility at Jaguey Station in partnership with Oleoducto de Los Llanos (ODL) in 2015. This unloading



facility is located 42 km away from the Llanos 34 block and allowed for reduced trucking distance and associated costs. Additionally, during 2018 we developed a project to connect the Llanos 34 field to the ODL pipeline via a flowline, which will be operational by the second quarter of 2019, allowing further cost efficiencies and increased operational reliability.

If we were to lose any of our customers, the loss could temporarily delay production and sale of our oil in the corresponding block. However, given the wide availability of customers for Colombian crude, we believe we could identify a substitute customer to purchase the impacted production volumes.

## Chile

Our customer base in Chile is limited in number and primarily consists of ENAP and Methanex. For the year ended December 31, 2018 we sold 100% of our oil production in Chile to ENAP and 99% of our gas production to Methanex, with sales to ENAP and Methanex accounting for 3% and 3%, respectively, of our total revenues in the same period.

On April 21, 2017, we renewed our sales agreement with ENAP. As part of this agreement, ENAP has committed to purchase our oil production in the Fell Block in the amounts that we produce, subject to the limitation of available storage capacity at the Gregorio Terminal. The sales agreement provides us with the option to interrupt sales to ENAP periodically if conditions in the export markets allow for more competitive price levels. While the agreement renews automatically on an annual basis, we typically revise the agreement every year to reflect changes in the global oil market and make certain adjustments based on ENAP's expenses related to storage at the Gregorio Terminal.

General commercial conditions of our contract with ENAP have remained stable over time. We deliver the oil we produce in the Fell Block to ENAP at the Gregorio Terminal, where ENAP assumes responsibility for the oil transferred. ENAP owns two refineries in Chile in the north central part of the country and must ship any oil from the Gregorio Terminal to these refineries unless it is consumed locally.

In March 2017, we executed a new gas supply agreement with Methanex effective from May 1, 2017 to December 31, 2026. Under the agreement, Methanex commits to purchase up to 400,000 SCM/d of gas produced by us. In 2018, due to the decline in gas production, the commitment was reduced to 315,000 SCM/d. We also hold an option to deliver up to 15% above this volume.

We gather the gas we produce in several wells through our own flow lines and inject it into several gas pipelines owned by ENAP. The transportation of the gas we sell to Methanex through these pipelines is pursuant to a private contract between Methanex and ENAP. We do not own any natural gas pipelines for the transportation of natural gas.
If we were to lose any one of our key customers in Chile, the loss could temporarily delay production and sale of our oil and gas in Chile. For a discussion of the risks associated with the loss of key customers, See "Item 3. Key Information—D. Risk factors—Risks relating to our business—We sell almost all of our natural gas in Chile to a single customer, who has in the past temporarily idled its principal facility" and "—We derive a significant portion of our revenues from sales to a few key customers."

## Brazil

Our production in Brazil consists of natural gas and condensate oil. Natural gas production is sold through a long-term, extendable agreement with Petrobras, which provides for the delivery and transportation of the gas produced in the Manati Field to the EVF gas treatment plant in the State of Bahia. The contract is in effect until delivery of the maximum committed volume or June 2030, whichever occurs first. The contract allows for sales above the maximum committed volume if mutually agreed by both seller and buyer. The price for the gas is fixed in reais and is adjusted annually in accordance with the Brazilian inflation index. In July 2015, we signed an amendment to the existing Gas Sales Agreement with Petrobras that covers 100% of the remaining gas reserves in the Manati Field.

The Manati Field is developed via a PMNT-1 production platform, which is connected to the Estação Vandemir Ferreira, or EVF, gas treatment plant through an offshore and onshore pipeline with a capacity of 335.5 mmcfpd (9.5 mm³ per day). The existing pipeline connects the field's platform to the EVF gas treatment plant, which is owned by the field's current concession holders. During 2015, in order to improve the field gas recovery and production, Manati's consortium built an onshore compression plant that started operating in August 2015, which allowed us to classify all existing proved undeveloped reserves as proved developed as of December 31, 2016. The BCAM-40 Concession, which includes the Manati Field, also benefits from the advantages of Petrobras's size. As the largest onshore and offshore operator in Brazil, Petrobras has the ability to mobilize the resources necessary to support its activities in the concession.

The condensate produced in the Manati Field is subject to a condensate purchase agreement with Petrobras, pursuant to which Petrobras has committed to purchase all of our condensate production in the Manati Field, but only in the amounts that we produce, without any minimum or maximum deliverable commitment from us. The agreement is valid through December 31, 2019, and can be renewed upon an amendment signed by Petrobras and the seller.

## Peru

In Peru, oil production is generally traded on a free market basis and commercial conditions generally follow international markers, normally WTI and Brent. As per the Joint Operating Agreement executed with Petroperu, Petroperu has the first option to acquire oil produced by us in the Morona Block by matching any offer received by third parties regarding such production.



Future production in the Morona Block is expected to be transported through the existing North Peruvian Pipeline to be sold to the domestic or export markets at the Bayovar port. The North Peruvian Pipeline and the Bayovar port are owned and operated by Petroperu, and regulated and supervised by Osinergmin, the regulatory body in the hydrocarbons sector. Transportation rates are negotiated with Petroperu. However, if an agreement cannot be reached between Petroperu and us, transportation rates will be determined by Osinergmin. The North Peruvian pipeline transported an average of 22,000 bopd in the first 9 months of 2018. On November 27, 2018, crude shipments on the North Line of the North Peruvian Pipeline were interrupted due to a blockage by a local community which resulted in a spill. In February 27, 2019, the Peruvian government reached an agreement with the local community that allowed the repairs to be made and the pipeline to restart operations in March 2019. See “Item 3. Risk factors—Risks relating to our business—Our inability to access needed equipment and infrastructure in a timely manner may hinder our access to oil and natural gas markets and generate significant incremental costs or delays in our oil and natural gas production.”

## Argentina

All the gas produced in Argentina is sold to Grupo Albanesi, a leading Argentine privately held conglomerate focused on the energy market that offers natural gas and power supply and transport services to its customers. We have an annual agreement in effect from May 2018 through April 2019. According to local practices, this agreement contains seasonal prices, splitting between winter and summer prices.

Our oil sales in Argentina are diversified across clients and delivery points. 30% of our production in Argentina (2% of consolidated revenues) is sold locally in the Neuquén Province and delivered at well-head. The remaining 70% (3% of consolidated revenues) is sold to major refineries in Argentina and delivered through pipeline. As usual in the local market, the sales agreements are executed for short-term renewable periods from one to three months.

## Significant Agreements

## Colombia

## E&P Contracts

We have entered into E&P Contracts granting us the right to explore and operate, as well as working interests in six blocks in Colombia. These E&P Contracts are generally divided into two periods: (1) the exploration period, which may be subdivided into various exploration phases and (2) the exploitation period, determined on a per-area basis and beginning on the date we declare an area to be commercially viable. Commercial viability is determined upon the completion of a specified evaluation program or as otherwise agreed by the parties to the relevant E&P Contract. The exploitation period for an area may be extended until such time as such area is no longer commercially viable and certain other conditions are met.

Pursuant to our E&P Contracts, we are required, as are all oil and gas companies undertaking exploratory and production activities in Colombia, to pay a royalty to the Colombian government based on our production of hydrocarbons, as of the time a field begins to produce. Under Law 756 of 2002, as modified by Law 1530 of 2012, the royalties we must pay in connection with our production of light and medium oil are calculated on a field-by-field basis. See Note 32.1 to our Consolidated Financial Statements.

Additionally, in the event that an exploitation area has produced amounts in excess of an aggregate amount established in the E&P Contract governing such area, the ANH is entitled to receive a “windfall profit,” to be paid periodically, calculated pursuant to such E&P Contract.

In each of the exploration and exploitation periods, we are also obligated to pay the ANH a subsoil use fee. During the exploration period, this fee is scaled depending on the contracted acreage. During the exploitation period, the fee is assessed on the amount of hydrocarbons produced, multiplied by a specified dollar amount per barrel of oil produced or thousand cubic feet of gas produced. Further, the ANH has the right to receive an additional fee when prices for oil or gas, as the case may be, exceed the prices set forth in the relevant E&P Contract.

Our E&P Contracts are generally subject to early termination for a breach by the parties, a default declaration, application of any of the contract's unilateral termination clauses or termination clauses mandated by Colombian law. Anticipated termination declared by the ANH results in the immediate enforcement of monetary guaranties against us and may result in an action for damages by the ANH. Pursuant to Colombian law, if certain conditions are met, the anticipated termination declared by the ANH may also result in a restriction on the ability to engage contracts with the Colombian government during a certain period of time. See "Item 3. Key Information—D. Risk factors—Risks relating to our business—Our contracts in obtaining rights to explore and develop oil and natural gas reserves are subject to contractual expiration dates and operating conditions, and our CEOPs, E&P Contracts and concession agreements are subject to early termination in certain circumstances."

Llanos 34 Block E&P Contract. Pursuant to an E&P Contract between Unión Temporal Llanos 34 (a consortium between Ramshorn and Winchester Oil and Gas - now GeoPark Colombia SAS) and the ANH that became effective as of March 13, 2009 ("Llanos 34 Block E&P Contract"), Unión Temporal Llanos 34 was granted the right to explore and operate the Llanos 34 Block, and we and Ramshorn were granted a 40% and a 60% working interest, respectively, in the Llanos 34 Block. We were also granted the right to operate the Llanos 34 Block. On December 16, 2009, Winchester Oil and Gas (now GeoPark Colombia) entered into a joint operating agreement with Ramshorn and P1 Energy with respect to our operations in the block. As of the date of this annual report, the members of the Union Temporal Llanos 34 are GeoPark Colombia SAS with 45%, and Parex Verano Limited with 55% working interest.



We are currently in an additional exploration period (the contract provides for two optional exploratory phases of 18 months each, in which the operator carries out exploratory activities in order to retain areas to explore) of the Llanos 34 Block E&P Contract with an exploitation program in execution over certain areas. The contract also provides for a six-year exploration period consisting of two three-year phases. It also provides for a 24-year exploitation period for each commercial area, which begins on the date on which such area is declared commercially viable. The exploitation period may be extended for periods of up to 10 years at a time until such time as the area is no longer commercially viable and certain conditions are met. We have presented evaluation programs to the ANH for the Tilo Field. We presented the declaration of commerciality of Max, Túa, Tarotaro, Tigana, Jacana and Chachalaca, respectively.

Pursuant to the Llanos 34 Block E&P Contract and applicable law, we are required to pay a royalty to the ANH based on hydrocarbons produced in the Llanos 34 Block. See Note 32.1 to our Consolidated Financial Statements.

Additionally, we are required to pay a subsoil use fee to the ANH. ANH also has the right to receive an additional fee when prices for oil or gas, as the case may be, exceed the prices set forth in the Llanos 34 Block E&P Contract. The ANH also has an additional economic right equivalent to 1% of production, net of royalties.

In accordance with the Llanos 34 Block operation contract, when the accumulated production of each field, including the royalties' volume, exceeds 5 million barrels and the WTI exceeds a defined base price, the Company should deliver to ANH a share of the production net of royalties in accordance with an established formula. See Note 32.1 to our Consolidated Financial Statements.

## Winchester and Luna Stock Purchase Agreement

Pursuant to the stock purchase agreement entered into on February 10, 2012 (the "Winchester Stock Purchase Agreement"), we agreed to pay the Sellers a total consideration of US$30.0 million, adjusted for working capital. Additionally, under the terms of the Winchester Stock Purchase Agreement, we are obligated to make certain payments to the Sellers based on the production and sale of hydrocarbons discovered by exploration wells drilled after October 25, 2011. Once the maximum earn-out amount is reached, we pay the Sellers quarterly overriding royalties in an amount equal to 4% of our net revenues from any new discoveries of oil. For the year ended December 31, 2018, we accrued and paid US$20.6 million and US$19.1 million with regards to this agreement.

## Chile

## CEOs

Currently, we have five CEOs in effect with Chile, one for each of the blocks in which we operate, which grant us the right to explore and exploit hydrocarbons in these blocks, determine our working interests in the blocks and appoint the operator of the blocks. These CEOs are divided into two phases: (1) an exploration phase, which is divided into two or more exploration periods, and which begins on the effectiveness date of the relevant CEOP, and (2) an exploitation phase, which is determined on a per-field basis, commencing on the date we declare a field to be commercially viable and ending with the term of the relevant CEOP. In order to transition from the exploration phase to an exploitation phase, we must declare a discovery of hydrocarbons to the Ministry of Energy. This is a unilateral declaration, which grants us the right to test a field for a limited period of time for commercial viability. If the field proves commercially viable, we must make a further unilateral declaration to the Ministry of Energy. In the exploration phase, we are obligated to fulfill a minimum work commitment, which generally includes the drilling of wells, the performance of 2D or 3D seismic surveys, minimum capital commitments and guaranties or letters of credit, as set forth in the relevant CEOP. We also have relinquishment obligations at the end of each period in the exploration phase in respect of those areas in which we have not made a declaration of discovery. We can also voluntarily relinquish areas in which we have not declared discoveries of hydrocarbons at any time, at no cost to us. In the exploitation phase, we generally do not face formal work commitments, other than the development plans we file with the Chilean Ministry of Energy for each field declared to be commercially viable.

Our CEOPs provide us with the right to receive a monthly remuneration from Chile, payable in petroleum and gas, based either on the amount of petroleum and gas production per field or according to Recovery Factor, which considers the ratio of hydrocarbon sales to total cost of production (capital expenditures plus operating expenses). Pursuant to Chilean law, the rights contained in a CEOP cannot be modified without consent of the parties.

Our CEOPs are subject to early termination in certain circumstances, which vary depending upon the phase of the CEOP. During the exploration phase, Chile may terminate a CEOP in circumstances including a failure by us to comply with minimum work commitments at the termination of any exploration period, or a failure to communicate our intention to proceed with the next exploration period 30 days prior to its termination, a failure to provide the Chilean Ministry of Energy the performance bonds required under the CEOP, a voluntary relinquishment by us of all areas under the CEOP or a failure by us to meet the requirements to enter into the exploitation phase upon the termination of the exploration phase. In the exploitation phase, Chile may terminate a CEOP if we stop performing any of the substantial obligations assumed under the CEOP without cause and do not cure such nonperformance pursuant to the terms of the concession, following notice of breach from the Chilean Ministry of Energy. Additionally, Chile may terminate the CEOP due to force majeure circumstances (as defined in the relevant CEOP). If Chile terminates a CEOP in the exploitation phase, we must transfer to Chile, free of charge, any productive wells and related facilities, provided that such transfer does not interfere with our abandonment obligations and excluding certain pipelines.



and other assets. Other than as provided in the relevant CEOP, Chile cannot unilaterally terminate a CEOP without due compensation. See "Item 3. Key Information—D. Risk factors—Risks relating to our business—Our contracts in obtaining rights to explore and develop oil and natural gas reserves are subject to contractual expiration dates and operating conditions, and our CEOPs, E&P Contracts and concession agreements are subject to early termination in certain circumstances."

Fell Block CEOP. On November 5, 2002, we acquired a percentage of rights and interests of the CEOP for the Fell Block with Chile, or the Fell Block CEOP, and on May 10, 2006, we became the sole owners, with 100% of the rights and interest in the Fell Block CEOP. Chile had originally entered into a CEOP for the Fell Block with ENAP and Cordex Petroleum Inc., or Cordex, on April 29, 1997, which had an effective date of August 25, 1997. The Fell Block CEOP grants us the exclusive right to explore and exploit hydrocarbons in the Fell Block and has a term of 35 years, beginning on the effective date. The Fell Block CEOP provided for a 14-year exploration period, composed of numerous phases that ended in 2011, and an up-to-35-year exploitation phase for each field.

The Fell Block CEOP provides us with a right to receive a monthly retribution from Chile payable in petroleum and gas, based on the following per-field formula: 95% of the oil produced in the field, for production of up to 5,000 bopd, ring fenced by field, and 97% of gas produced in the field, for production of up to 882.9 mmcfpd. In the event that we exceed these levels of production, our monthly retribution from Chile will decrease based on a sliding scale set forth under the Fell Block CEOP to a maximum of 50% of the oil and 60% of the gas that we produce per field.

TDF Blocks CEOPs. After an international bidding process led by ENAP and the Chilean Ministry of Energy, in March and April, 2012, we, together with ENAP, signed 3 new CEOPs for the Isla Norte, Campanario and Flamenco Blocks, all of them located in Tierra del Fuego (“TDF”), Magallanes region. Our working interest is 60% in Isla Norte and 50% in Campanario and Flamenco Blocks. The CEOPs have a term of 32 years, with an initial exploration phase which last for 7 years, including a first exploration period of 3 years in which we are committed to developing several exploration activities including 1,500 square kilometers of 3D seismic registration, and the drilling of 21 exploratory wells.

The hydrocarbon discoveries opened up an exploitation phase that lasts up to 32 years. We discovered hydrocarbon fields in the 3 blocks, starting in 2013 in the Flamenco Block, and in 2014 in both Campanario and Isla Norte Blocks. The CEOPs provide us with a right to receive a remuneration payable by means of a fraction of the production sold, which in the TDF Blocks is based on a formula depending on the recovery of the total accumulated expenses incurred (capital expenditure plus operational expenditure plus administrative and general expenses). While the recovery factor is less than 1.0, the remuneration is 95% of the hydrocarbons produced, either oil or gas. If the recovery factor surpasses 1.0, a formula applies reducing gradually the remuneration fraction to a minimum of 75% when the recovery factor is 2.5 times the total accumulated expenses.

Neuquén Exploitation Concessions. After receiving authorization in March 27, 2018 from the Province of Neuquén under Provincial Decree 266/2018, we closed the acquisition of a 100% interest in the Aguada Baguales, El Porvenir and Puesto Touquet hydrocarbon exploitation concessions from Pluspetrol S.A., together with an ancillary transportation concession over a natural gas pipeline from Puesto Touquet to Plaza Huincul, all in the Neuquén Basin in Argentina. These concessions had been originally granted to Pluspetrol S.A. for a term of 25 years in 1990 (Aguada Baguales and El Porvenir Blocks) and 1992 (Puesto Touquet Block). In 2008, the Province of Neuquén granted a ten year extension of these concessions in consideration of an investment program which included development, exploration and environmental remediation programs and a payment of a cash bonus in proportion to the in-situ hydrocarbon reserves of the blocks. At least one year prior to the end of the current ten year extension period, we are entitled to request a further ten year extension to these concessions in consideration for continued investments, an incremental 3% royalty (resulting in an aggregate 18% royalty) and a cash bonus equal to 2% of the then existing in-situ reserves.

Under these concessions, we are entitled to the exclusive right to develop the entire acreage of the concessions, produce, freely dispose and market all hydrocarbons we lift under a royalty tax system.

## LGI Termination Agreement

Pursuant to the sale and purchase agreement entered into on November 28, 2018 (the "LGI Termination Agreement"), we agreed to pay LGI a total consideration of up to US$126 million for its entire equity interest in Geopark Chile, Geopark TdF and Geopark Colombia Coöperatie U.A. The acquisition price includes a fixed payment of US$81 million paid at closing, plus two equal installments of US$15 million each, to be paid in June 2019 and June 2020, respectively, and three contingent payments of US$5 million each, which could accrue over the next three years, subject to certain production thresholds being exceeded in the Llanos 34 Block. As a consequence of the LGI Termination Agreement we have become sole shareholder of the entities referred to above. See "Item 7. Major Shareholders and Related Parties—B. Related Party Transactions—LGI Termination Agreement."

## Brazil

## Overview of concession agreements

The Brazilian oil and gas industry is governed mainly by the Brazilian Petroleum Law, which provides for the granting of concessions to operate petroleum and gas fields in Brazil, subject to oversight by the ANP. A concession agreement is divided into two phases: (1) exploration and (2) development and production. The exploration phase, which is further divided into two subsequent exploratory periods, the first of which begins on the date of execution of the concession agreement, can last from three to eight years (subject to earlier termination upon the total return of the concession area



or the declaration of commercial viability with respect to a given area), while the development and production phase, which begins for each field on the date a declaration of commercial viability is submitted to the ANP, can last up to 27 years. Upon each declaration of commercial viability, a concessionaire must submit to the ANP a development plan for the field within 180 days. The concessions may be renewed for an additional period equal to their original term if renewal is requested with at least 12 months' notice, and provided that a default under the concession agreement has not occurred and is then continuing. Even if obligations have been fulfilled under the concession agreement and the renewal request was appropriately filed, renewal of the concession is subject to the discretion of the ANP.

The main terms and conditions of a concession agreement are set forth in Article 43 of the Brazilian Petroleum Law, and include: (1) definition of the concession area; (2) validity and terms for exploration and production activities; (3) conditions for the return of concession areas; (4) guarantees to be provided by the concessionaire to ensure compliance with the concession agreement, including required investments during each phase; (5) penalties in the event of noncompliance with the terms of the concession agreement; (6) procedures related to the assignment of the agreement; and (7) rules for the return and vacancy of areas, including removal of equipment and facilities and the return of assets. Assignments of participation interests in a concession are subject to the approval of the ANP, and the replacement of a performance guarantee is treated as an assignment.

The main rights of the concessionaires (including us in our concession agreements) are: (1) the exclusive right of drilling and production in the concession area; (2) the ownership of the hydrocarbons produced; (3) the right to sell the hydrocarbons produced; and (4) the right to export the hydrocarbons produced. However, a concession agreement set forth that, in the event of a risk of a fuel supply shortage in Brazil, the concessionaire must fulfill the needs of the domestic market. In order to ensure the domestic supply, the Brazilian Petroleum Law granted the ANP the power to control the export of oil, natural gas and oil products.

Among the main obligations of the concessionaire are: (1) the assumption of costs and risks related to the exploration and production of hydrocarbons, including responsibility for environmental damages; (2) compliance with the requirements relating to acquisition of assets and services from domestic suppliers; (3) compliance with the requirements relating to execution of the minimum exploration program proposed in the winning bid; (4) activities for the conservation of reservoirs; (5) periodic reporting to the ANP; (6) payments for government participation; and (7) responsibility for the costs associated with the deactivation and abandonment of the facilities in accordance with Brazilian law and best practices in the oil industry.

A concessionaire is required to pay to the Brazilian government the following:
• a license fee;

• rent for the occupation or retention of areas;

• a special participation fee;
• royalties; and
• taxes.

Rental fees for the occupation and maintenance of the concession areas are payable annually. For purposes of calculating these fees, the ANP takes into consideration factors such as the location and size of the relevant concession, the sedimentary basin and the geological characteristics of the relevant concession.

A special participation fee is an extraordinary charge that concessionaires must pay in the event of obtaining high production volumes and/or profitability from oil fields, according to criteria established by applicable regulations, and is payable on a quarterly basis for each field from the date on which extraordinary production occurs. This participation fee, whenever due, varies between 0% and 40% of net revenues depending on (1) the volume of production and (2) whether the concession is onshore or in shallow water or deep water. Under the Brazilian Petroleum Law and applicable regulations issued by the ANP, the special participation fee is calculated based on the quarterly net revenues of each field, which consist of gross revenues calculated using reference prices established by the ANP (reflecting international prices and the exchange rate for the period) less:

• royalties paid;

• investment in exploration;

• operational costs; and

• depreciation adjustments and applicable taxes.

The Brazilian Petroleum Law also requires that the concessionaire of onshore fields pay to the landowners a special participation fee that varies between 0.5% to 1.0% of the net operational income originated by the field production.

BCAM-40 Concession Agreement. On August 6, 1998, the ANP and Petrobras executed the concession agreement governing the BCAM-40 Concession, or the BCAM-40 Concession Agreement, following the first round of bidding, referred to as Bid Round Zero, under the regime established by the Brazilian Petroleum Law. The exploitation phase will end in November 2029. On September 11, 2009, Petrobras announced the termination of BCAM-40 Concession's exploration phase and the return of the exploratory area of the concession to the ANP, except for the Manati Field and the Camarão Norte Field.

Under the BCAM-40 Concession Agreement, the ANP is entitled to a monthly royalty payment equal to 7.5% of the production of oil and natural gas in the concession area. In addition, in case the special participation fee of 10% shall be applicable for a field in any quarter of the calendar year, the concessionaire is obliged to make qualified research and development investments equivalent to one percent of the field's gross revenue. Area retention payments are also applicable under the concession agreement. We acquired Rio das Contas' 10% participation interest in the BCAM-40 Concession on March 31, 2014.



## Rounds 11, 12, 13 and 14 Concession Agreements.

Under the Rounds 11, 12, 13 and 14 Concession Agreements, the ANP is entitled to a monthly royalty corresponding to up to 10% of the production of oil and natural gas in the concession area, in addition to the special participation fee described above, the payment for the occupation of the concession area of approximately R$7,600 per year and the payment to the owners of the land of the concession equivalent to one percent of the oil and natural gas produced in the concession area.

During bidding, a work program offer is made in the form of work units and the ANP asks for a guarantee of a monetary amount proportional to the offered units. However, depending on the work performed by the operator, the actual work program investment might have a different value to the guaranteed value.

## Overview of consortium agreements

A consortium agreement is a standard document describing consortium members' respective percentages of participation and appointment of the operator. It generally provides for joint execution of oil and natural gas exploration, development and production activities in each of the concession areas. These agreements set forth the allocation of expenses for each of the parties with respect to their respective participation interests in the concession. The agreements are supplemented by joint operating agreements, which are private instruments that typically regulate the aggregation of funds, the sharing of costs, mitigation of operational risks, preemptive rights and the operator's activities.

An important characteristic of the consortia for exploration and production of oil and natural gas that differs from other consortia (Article 278, paragraph 1, of the Brazilian Corporate Law) is the joint liability among consortium members as established in the Brazilian Petroleum Law (Article 38, item II).

## BCAM-40 Consortium Agreement

On January 14, 2000, Petrobras, Enauta and Petroserv entered into a consortium agreement, or the BCAM-40 Consortium Agreement, for the performance of the BCAM-40 Concession Agreement. Petrobras is the operator of the BCAM-40 concession, with a 35% participation interest. Enauta, Brasoil and Rio das Contas have a 45%, 10% and 10% participation interest, respectively. The BCAM-40 Consortium Agreement has a specified term of 40 years, terminating on January 14, 2040 and, at the time the obligations undertaken in the agreement are fully completed, the parties will have the right to terminate it. The BCAM-40 Concession consortium has also entered into a joint operating agreement, which sets out the rights and obligations of the parties in respect of the operations in the concession. Petrobras Natural Gas Purchase Agreement

Enauta, GeoPark Brasil, Brasoil and Petrobras are party to a natural gas purchase agreement providing for the sale of natural gas by Enauta, GeoPark Brasil and Brasoil to Petrobras, in an amount of 812 billion cubic feet ("bcf") over the term of agreement. The Petrobras Natural Gas Purchase Agreement is valid until the earlier of Petrobras' receipt of this total contractual quantity or June 30, 2030. The agreement may not be fully or partially assigned except upon execution of an assignment agreement with the written consent of the other parties, which consent may not be unreasonably withheld provided that certain prerequisites have been met.

The agreement provides for the provision of “daily contractual quantities” to Petrobras peaking at 170.3 mmcfd in 2016 and progressively dropping until 2030. The parties may agree to lower volumes as dictated by Manati Field’s depletion. Pursuant to the agreement, the base price is denominated in reais and is adjusted annually for inflation pursuant to the general index of market prices (IGPM). Additionally, the gas price applicable on a given day is subject to reduction as a result of the gas quantity acquired by Petrobras above the volume of the annual TOP commitment (85% of the daily contracted quantity) in effect on such day. The Petrobras Natural Gas Purchase Agreement provides that all of the Manati Field’s daily production be sold to Petrobras.

## Peru

## Morona Block

On October 1, 2014, we entered into an agreement with Petroperu to acquire an interest in and operate the Morona Block, located in Northern Peru. We will assume a 75% working interest of the Morona Block, with Petroperu retaining a 25% working interest. On December 1, 2016, through Supreme Decree N° 031-2016-MEN the Peruvian government approved the amendment to the License Contract of Block 64 (Morona Block) appointing GeoPark as operator and holder of 75% of the Contract.

In Peru, there is a 5-20% sliding scale royalty rate, depending on production levels. Production less than 5,000 bopd is assessed at a royalty rate of 5%. For production between 5,000 and 100,000 bopd there is a linear sliding scale between 5% and 20%. Production over 100,000 bopd has a flat royalty of 20%.

See “Item 4. Information on the Company—B. Business Overview—Our operations—Operations in Peru—Morona Block.”

## Argentina

## Overview of exploration permits

Our exploration permits grant to us and our partners the exclusive right to explore for hydrocarbons and declare a commercial discovery within the acreage of our permits. Our exploration permits are made up of three subperiods, each lasting 3, 2 and 1 year(s), respectively, plus an extension period of up to 5 years.

We are bound to pursue specific minimum work or investment commitments during each of the subperiods of each exploration permit. Such exploration works are valued in work units assigned to each particular type of work under the applicable bidding conditions.

Work and investment programs for the permits are required to be assured by issuing a performance bond for the value of the committed work plan.



Under the terms of our exploration permits and concession agreements, we are entitled to our proportionate share of the hydrocarbons production lifted from each block. The Province of Mendoza's state owned company, EMESA, has a 10% carried interest in each of the Puelen and Sierra del Nevado permits and any future exploitation concessions, while there is no governmental participation in the CN-V Block. During the term of our exploration permits, we are also required, under Argentine law, to pay a 15% royalty to the province on both oil and gas sales. In case we progress to an exploitation concession, the applicable royalty rate will reduce to a 12% royalty. We also pay annual surface rental fees established under Hydrocarbons Law 17,319 ("Hydrocarbons Law") and Resolution 588/98 of the Argentine Secretariat of Energy and Decree 1454/2007, and certain landowner fees.

Our Argentine exploration permits have no change of control provisions, though any assignment of these concessions is subject to the prior authorization by the executive branch of the Province of Mendoza and rights of first refusal in favor of our partners and EMESA, in the case of the Puelen and Sierra del Nevado permits. Each of these permits or future concessions can be terminated for default in payment obligations and/or breach of material statutory or regulatory obligations. We are subject to the obligation to relinquish at least 50% of the acreage of each exploration permit at the end of each exploration subperiod. We may also voluntarily relinquish acreage to the provincial authorities.

Our Argentine exploration permits are governed by the laws of Argentina and the resolution of any disputes must be sought in the Mendoza Provincial Courts.

If and when we make a commercial discovery in one or more of our exploration permits, we will have the right to request and obtain an exploitation concession to produce hydrocarbons in the block for 25 years, with an optional extension of up to 10 years. We also receive the right to be granted a 35-year oil transport concession to build and make use of pipelines or other transport facilities beyond the boundaries of the concession.

Additionally, oil and gas producers in Argentina must grant a privilege to the domestic market to the detriment of the export market, including hydrocarbon export restrictions, domestic price controls, export duties and domestic market supplier obligations.

## Pluspetrol Asset Purchase Agreement

Pursuant to the APA that we entered into on December 18, 2017 with Pluspetrol, we agreed to acquire a 100% working interest and operatorship of the Aguada Baguales, El Porvenir and Puesto Touquet blocks in Argentina for a total consideration of $52 million. The blocks include estimated oil and gas production of 2,700 boepd (70% light oil and 30% gas), 137,000 acres well-positioned in the Neuquén Basin and production facilities, including hydrocarbons treatment, storage, and delivery infrastructure.

We paid the consideration using proceeds from the offering of the Notes due 2024. The acquisition of the blocks closed on March 27, 2018.

## Title to properties

In each of the countries in which we operate, the state is the exclusive owner of all hydrocarbon resources located in such country and has full authority to determine the rights, royalties or compensation to be paid by private investors for the exploration or production of any hydrocarbon reserves. In Chile, the Republic of Chile grants such rights through a CEOP. In Colombia, the Republic of Colombia grants such rights through E&P Contracts or contracts of association. In Argentina, the Argentine Republic grants such rights through exploitation concessions. In Brazil, the Federative Republic of Brazil grants such rights pursuant to concession agreements. See "Item 3. Key Information—D. Risk factors—Risks relating to the countries in which we operate—Oil and natural gas companies in Colombia, Chile, Brazil, Argentina and Peru do not own any of the oil and natural gas reserves in such countries." Other than as specified in this annual report, we believe that we have satisfactory rights to exploit or benefit economically from the oil and gas reserves in the blocks in which we have an interest in accordance with standards generally accepted in the international oil and gas industry. Our CEOPs, E&P Contracts, contracts of association, exploitation concessions and concession agreements are subject to customary royalty and other interests, liens under operating agreements and other burdens, restrictions and encumbrances customary in the oil and gas industry that we believe do not materially interfere with the use of or affect the carrying value of our interests. See "Item 3. Key Information—D. Risk factors—Risks relating to our business—We are not, and may not be in the future, the sole owner or operator of all of our licensed areas and do not, and may not in the future, hold all of the working interests in certain of our licensed areas. Therefore, we may not be able to control the timing of exploration or development efforts, associated costs, or the rate of production of any non-operated and, to an extent, any non-wholly-owned, assets."

## Our customers

In Colombia, our primary customer is Trafigura, and who represented 82% of our total revenues for the year ended December 31, 2018. In Chile, our primary customers are ENAP and Methanex. As of December 31, 2018, ENAP purchased all of our Chilean oil and condensate production and Methanex purchased almost all of our natural gas production in Chile, and represented 3% and 3%, respectively, of our total revenues for the year ended December 31, 2018. In Brazil, all of our hydrocarbons in Manati are sold to Petrobras. In Argentina, all the gas produced is sold to Grupo Albanesi and represented 1% of our total revenues. Our oil production in Argentina is split between local buyers in the Neuquén Province, delivered at well-head (2% of consolidated revenues) and major refineries, delivered through pipeline (3% of consolidated revenues). In Peru, our primary customers are local refineries (Petroperu or Repsol) or the export market. Petroperu, has the first option to acquire the oil produced by us in the Morona Block by matching any offer received by third parties regarding such production.

## Seasonality

Although there is some historical seasonality to the prices that we receive



for our production, the impact of such seasonality has not been material. Seasonality has also not played a significant role in our ability to conduct our operations, including drilling and completion activities.

However, as the Morona Block is located in a remote area, the development of the project depends on significant infrastructure being built which can be impacted by seasonal weather patterns, including rain. Since there are no roads available in the surrounding area, logistics will be performed by helicopters or barges during specific seasons of the year.

We take such seasonality into account in planning for and conducting our operations, such that the impact on our overall business is not material.

## Our competition

The oil and gas industry is competitive, and we may encounter strong competition from other independent operators and from major state-owned oil companies in acquiring and developing licenses in the countries where we operate or plan to operate.

Many of these competitors have financial and technical resources and personnel substantially larger than ours. As a result, our competitors may be able to pay more for desirable oil and natural gas assets, or to evaluate, bid for and purchase a greater number of licenses than our financial or personnel resources will permit. Furthermore, these companies may also be better able to withstand the financial pressures of unsuccessful wells, sustained periods of volatility in financial and commodities markets and generally adverse global and industry-wide economic conditions, and may be better able to absorb the burdens resulting from changes in relevant laws and regulations, which may adversely affect our competitive position. See “Item 3. Key Information—D. Risk factors—Risks relating to our business—Competition in the oil and natural gas industry is intense, which makes it difficult for us to attract capital, acquire properties and prospects, market oil and natural gas and secure trained personnel.”

We may also be affected by competition for drilling rigs and the availability of related equipment. Higher commodity prices generally increase the demand for drilling rigs, supplies, services, equipment and crews, and can lead to shortages of, and increasing costs for, drilling equipment, services and personnel. Shortages of, or increasing costs for, experienced drilling crews and equipment and services could restrict our ability to drill wells and conduct our operations.

## Health, safety and environmental matters

## General

Our operations are subject to various stringent and complex international, federal, state and local environmental, health and safety laws and regulations in the countries in which we operate. These laws and regulations govern matters including the emission and discharge of pollutants into the ground, air or water; the generation, storage, handling, use and transportation of regulated materials; and human health and safety. These laws and regulations may, among other things:

• require the acquisition of various permits or other authorizations or the preparation of environmental assessments, studies or plans (such as well closure plans) before seismic or drilling activity commences;

• enjoin some or all of the operations of facilities deemed not in compliance with permits;

• restrict the types, quantities or concentration of various substances that can be released into the environment related to oil and natural gas drilling, production and transportation activities;

• require establishing and maintaining bonds, reserves or other commitments to plug and abandon wells;

• limit or prohibit seismic and drilling activities in certain locations lying within or near protected or environmentally sensitive areas;

• require preventative measures to mitigate pollution from our operations, which, if not undertaken, could subject us to substantial penalties; and

• require us to maintain a safe and healthy working environment for all employees, contractors and visitors in accordance with applicable regulations and industry best practices.

These laws and regulations may also restrict the rate of oil and natural gas production below the rate that would otherwise be possible. Compliance with these laws can be costly. The regulatory burden on the oil and gas industry increases the cost of doing business in the industry and consequently affects profitability.

Public interest in the protection of the environment continues to increase. Drilling in some areas has been opposed by certain community and environmental groups and, in other areas, has been restricted.

## Climate change

Both our operations and the combustion of oil and natural gas-based products results in the emission of greenhouse gases, which may contribute to global climate change. Climate change regulation has gained momentum in recent years internationally and at the federal, regional, state and local levels. On the international level, various nations have committed to reducing their greenhouse gas emissions pursuant to the Kyoto Protocol. The Kyoto Protocol was set to expire in 2012. In late 2011, an international climate change conference in Durban, South Africa resulted in, among other things, an agreement to negotiate a new climate change regime by 2015 that would aim to cover all major greenhouse gas emitters worldwide, including the U.S., and take effect by 2020. In November and December 2012, at an international meeting held in Doha, Qatar, the Kyoto Protocol was extended by amendment until 2020. In addition, the Durban agreement to develop the protocol’s successor by 2015 and implement it by 2020 was reinforced. We are committed to controlling the emission of greenhouse gases and implementing available technologies to reduce the impact caused by our operations. For example, during 2016 we began a migration plan to replace diesel with natural gas and electric generation.



## Our HSE Management System

Our health, safety and environmental management plan is focused on undertaking realistic and practical programs based on recognized world practices. Our emphasis is on building key principles and company-wide ownership and then expanding programs as we continue growing. Our S.P.E.E.D. philosophy and our HSE Plan have been developed with reference to ISO 14001 for environmental management issues, ISO 45000 for occupational health and safety management issues, SA 8000 for social accountability and workers' rights issues and applicable World Bank Standards.

## Our Environmental Policy

Our policy looks forward to meet or exceed environmental regulations in the countries in which we operate. We believe that oil and gas can be produced in an environmentally-responsible manner with proper care, understanding and management. Within our S.P.E.E.D. philosophy we have a team that is exclusively focused on securing the environmental authorizations and permits for the projects we undertake. This professional and trained team, specialized in environmental issues, is also responsible for the achievement of the environmental standards set by our Board of Directors and for training and supporting our personnel. Our senior executives, personnel in the field, visitors and contractors have also received training in proper environmental management.

## Our Health and Safety Policy

We continue looking for the best tools to manage our health and safety policy. In 2018 we started the implementation of our program called SOS (Safety Operational Standards) that contributes to building better practices to control and minimize risks in our daily operations. Since 2016 we have also implemented the Proactive Observation Program, HSE training, work permits, internal audits, drills, pre-job meetings and job safety analysis, among others.

As of December 31, 2018, on the last 12-month basis, our HSE development statistics workforce shows that Lost Time Injury Frequency (LTIF) was 0.42 (out of every 1,000,000 worked hours), our Total Recordable Incident Rate (TRIR) was 1.25 (out of every 1,000,000 worked hours) and we had no fatal incidents related to operations in 2018.

In 2016, we subscribed to the International Association of Oil and Gas Producers in order to align our Management System and policies with the best international standards.

## Certain Bermuda law considerations

As a Bermuda exempted company, we and our Bermuda subsidiaries are subject to regulation in Bermuda. We have been designated by the BMA as a non-resident for Bermuda exchange control purposes. This designation allows us to engage in transactions in currencies other than the Bermuda dollar, and there are no restrictions on our ability to transfer funds (other than funds denominated in Bermuda dollars) in and out of Bermuda.

Under Bermuda’s law, “exempted” companies are companies formed for the purpose of conducting business outside Bermuda from a principal place of business in Bermuda. As exempted companies, we and our Bermuda subsidiaries may not, without a license or consent granted by the Minister of Finance of Bermuda, participate in certain business transactions, including transactions involving Bermuda landholding rights and the carrying on of business of any kind for which we or our Bermuda subsidiaries are not licensed in Bermuda.

## Insurance

We maintain insurance coverage of types and amounts that we believe to be customary and reasonable for companies of our size and with similar operations in the oil and gas industry. However, as is customary in the industry, we do not insure fully against all risks associated with our business, either because such insurance is not available or because premium costs are considered prohibitive.

Currently, our insurance program includes, among other things, construction, fire, vehicle, technical, umbrella liability, director’s and officer’s liability and employer’s liability coverage. Our insurance includes various limits and deductibles or retentions, which must be met prior to or in conjunction with recovery. A loss not fully covered by insurance could have a materially adverse effect on our business, financial condition and results of operations. See “Item 3. Key Information—D. Risk factors—Risks relating to our business—Oil and gas operations contain a high degree of risk and we may not be fully insured against all risks we face in our business.”

## Industry and regulatory framework
Colombia

## Regulation of the oil and gas industry

The ANH is responsible for managing all exploration lands not subject to previously existing association contracts with Ecopetrol. The ANH began offering all undeveloped and unlicensed exploration areas in the country under E&P Contracts and Technical Evaluation Agreements, or TEAs, which resulted in a significant increase in Colombian exploration activity and competition, according to the ANH. The ANH is also in charge of negotiating and executing contracts through “direct negotiation” mechanisms with attention to special conditions in the areas to be explored, however the ANH has not issued the regulation for such direct granting of contracts. The regulatory landscape in Colombia has recently changed. The regime for the ANH’s contracts is set forth in Agreement 008 of 2004 and Agreement 004 of 2012. Accord 008 of 2004 issued by the Directive Council of the ANH, as repealed and replaced by Accord 004 of 2012, sets forth the necessary steps for entering into E&P Contracts with the ANH. This Agreement regulates E&P contracts entered into from May 4, 2012. E&P contracts entered into before that date are still regulated by Agreement 008 of 2004. Due to the oil price crisis of 2015, the ANH implemented transitory measures through Agreements 002, 003, 004 and 005 of 2015. On May 18, 2017, the ANH issued Agreement 002, which repealed and replaced Agreement 004 of 2012 and transitory measures adopted in 2014 and 2015. Agreement 002 of 2017 established



rules for the allocation of hydrocarbon areas and adopted criteria for the exploration and exploitation of hydrocarbons owned by Colombia, including the selection of contractors, and management, execution, termination, liquidation, monitoring, control and supervision of corresponding contracts. Agreement 002 of 2017 regulates contracts entered into from May 18, 2017. E&P contracts entered into before that date are still regulated by the Agreements under which they were executed.

## Regulatory framework

Regulation of exploration and production activities

Pursuant to Colombian law, the state is the exclusive owner of all hydrocarbon resources located in Colombia and has full authority to determine the rights, royalties or compensation to be paid by private investors for the exploration or production of any hydrocarbon reserves. The Ministry of Mines and Energy is the authority responsible for regulating all activities related to the exploration and production of hydrocarbons in Colombia.

Decree Law 1056 of 1953 (Código de Petróleos), or the Petroleum Code, establishes the general procedures and requirements that must be completed by a private investor and disclosure procedures that need to be followed during the performance of these activities.

Exploration and production activities were governed by Decree 1895 of 1973 until September 2009. Decree Law 2310 of 1974 (as complemented by Decree 743 of 1975) governed the contracts and contracting processes carried out by Ecopetrol and the rules applicable to such contracts, and also provided that Ecopetrol was responsible for administering the hydrocarbons resources in the Country. Decree 2310 of 1974 was replaced by Decree Law 1760 of 2003, but all agreements entered into by us prior to 2003 with other oil companies are still regulated by Decree 2310 of 1974.

Resolution 18-1495 of 2009, modified by Resolution 40048 of 2015, establishes a series of regulations regarding hydrocarbon exploration and exploitation. In the E&P Contracts, operators are afforded access to blocks by committing to an exploration work program. These E&P Contracts provide companies with 100% of new production, less the participation of the ANH, which participation may differ for each E&P Contract and depends on the percentage that each company has offered to the ANH in order to be granted with a block, subject to an initial royalty payment of 8% and the payment of income taxes of 33%. In addition, the Colombian government also introduced TEAs, in which companies that enter into TEAs are the only ones to have the right to explore, evaluate and select desirable exploration areas by executing seismic and/or drilling stratigraphic wells and to propose work commitments on those areas, and have a preemptive right to enter into an E&P Contract, thereby providing companies with low-cost access to larger areas for preliminary evaluation prior to committing to broader exploration programs. A preemptive right is granted to convert the TEA into an E&P Contract. Exploration activities can only be carried out by the TEA contractor.
Pursuant to Colombian law, companies are obligated to pay royalties (a percentage of their production) to the ANH in kind or in money as per ANH's instruction and pursuant to the E&P Contracts, companies must pay ANH an economic right called participating interest in the production, among other economic rights established in the E&P Contracts (i.e. high price provision, technology transfer, use of the subsurface). Producing fields pay royalties in accordance with the applicable law at the time of the discovery.

Additionally, in February 2019 the ANH published the Terms of Reference for the Permanent Competitive Bidding Process in which initially 20 blocks will be offered to interested qualified bidders.

## Taxation

The Tax Statute and Law 9 of 1991 provide the primary features of the oil and gas industry’s tax and exchange system in Colombia. Generally, national taxes under the general tax statute apply to all taxpayers, regardless of industry. The main taxes currently in effect—after the December 2016 tax reform discussed below—are the income tax (40% for 2017, 37% for 2018 and 33% for 2019 onwards), sales or value added tax (19%), and the tax on financial transaction (0.4%). Additional regional taxes also apply. Colombia has entered into a number of international tax treaties to avoid double taxation and prevent tax evasion in matters of income tax and net asset tax.

Decree 2080 of 2000 (amended by Decree 4800 of 2010), or the international investment regime, regulates foreign capital investment in Colombia. Resolution 8 of the board of the Colombian Central Bank, or the Exchange Statute, and its amendments contain provisions governing exchange operations. Articles 48 to 52 of Resolution 8 provide for a special exchange regime for the oil industry that removes the obligation of repayment to the foreign exchange market currency from foreign currency sales made by foreign oil companies. Such companies may not acquire foreign currency in the exchange market under any circumstances and must reinstate in the foreign exchange market the capital required in order to meet expenses in Colombian legal currency. Companies can avoid participating in this special oil and gas exchange regime, however, by informing the Colombian Central Bank, in which case they will be subject to the general exchange regime of Resolution 8 and may not be able to access the special exchange regime for a period of 10 years.

In December 2018, a new tax reform was enacted in Colombia. The legislation included significant changes in certain corporate income tax, statutory income tax and legal provisions. This tax reform became effective on January 1, 2019.

The legislation included the progressive reduction of the general corporate income tax rate, previously set at 40% for 2017 and 37% for 2018, as follows:

33% in 2019, 32% in 2020, 31% in 2021 and 30% in 2022 and onwards. Other changes that affect the Group are the following:

• The withholding tax rate on dividends for non-resident shareholders was increased from 5% to 7.5%.



• The withholding tax rates were increased from 15% to 20% for payments to non-residents, related to consultancies, technical services, technical assistance, software and interest on loans of less than one year (for loans with more than a year of maturity, the 15% rate remained unchanged).

• The withholding tax rate for payments to entities resident in non-cooperative countries, with no or low taxation, or subject to a preferential tax regime, was increased from 15% to the corporate income tax rate (33 % for 2019, 32% for 2020, 31% for 2021 and 30% for 2022 and onwards).

• The deduction of interest attributed to a permanent establishment in Colombia by its head office was limited to when they have been subject to withholding tax.

• Regarding undercapitalization, the debt limit which interests can be deducted, for income tax purposes, was reduced to two times the net equity of the taxpayer as of December 31 of the previous year.

• Transfers of participations in foreign entities that represent indirect disposals of assets in Colombia are subject to income tax or occasional earnings tax.
• VAT paid for acquisition of productive fixed assets can be discounted from the taxpayer’s income tax

An audit benefit was granted by the reform, establishing that tax returns for the 2019 and 2020 fiscal years showing a net income tax 30% or 20% higher, respectively, than the one declared in the previous year would be considered definitive 6 months or 12 months after they became due, also respectively, if there were no objections or requests from the tax authority.

## Chile

## Regulation of the oil and gas industry

Under the Chilean Constitution, the state is the exclusive owner of all mineral and fossil substances, including hydrocarbons, regardless of who owns the land on which the reserves are located. The exploration and exploitation of hydrocarbons may be carried out by the state, companies owned by the state or private entities through administrative concessions granted by the President of Chile by Supreme Decree or CEOs executed by the Minister of Energy. Exploitation rights granted to private companies are subject to special taxes and/or royalty payments. The hydrocarbon exploration and exploitation industry is supervised by the Chilean Ministry of Energy.

In Chile, a participant is granted rights to explore and exploit certain assets under a CEOP. If a participant breaches certain obligations under a CEOP, the participant may lose the right to exploit certain areas or may be required to return all or a portion of the awarded areas to Chile with no right of compensation. Although the government of Chile cannot unilaterally modify the rights granted in the CEOP once it is signed, exploration and exploitation are nonetheless subject to significant government regulations, such as regulations concerning the environment, tort liability, health and safety and labor.

## Regulatory framework

Regulation of exploration and production activities
Oil and gas exploration and development is governed by the Political Constitution of the Republic of Chile and Decree with Law Force No 2 of 1986 of the Ministry of Mines, which set forth the revised text of the Decree Law 1089 of 1975, on CEOs. However, the right to explore and develop fields is granted for each area under a CEOP between Chile and the relevant contractors. The CEOP establishes the legal framework for hydrocarbon activities, including, among other things, minimum investment commitments, exploration and exploitation phase durations, compensation for the private company (either in cash or in kind) and the applicable tax regime. Accordingly, all the provisions governing the exploitation and development of our Chilean operations are contained in our CEOs and the CEOs constitute all the licenses that we need in order to own, operate, import and export any of the equipment used in our business and to conduct our gas and petroleum operations in Chile.

Under Chilean law, the surface landowners have no property rights over the minerals found under the surface of their land. Subsurface rights do not generate any surface rights, except the right to impose legal easements or rights of way. Easements or rights of way can be individually negotiated with individual surface land owners or can be granted without the consent of the landowner through judicial process. Pursuant to the Chilean Code of Mines, a judge can permit a party to use an easement pending final adjudication and settlement of compensation for the affected landowner.

## Taxation

With regard to indirect taxes on hydrocarbon exploitation, the general rule is that hydrocarbons are transferred to the contractor (its retribution under the CEOP), and those re-acquisitions from the contractor performed by Chile or its enterprises, as well as their corresponding acts, contracts and documents, are tax exempt. In addition, hydrocarbon exports by the contractor are also tax exempt. With regard to income taxes, as provided by article 5 of Decree Law No. 1,089, the contractor is subject either to a single tax calculated on its retribution, equal to 50% of such retribution, or to the general income tax regime established in the Income Tax Law (Decree Law No. 824 of 1974), in force at the time of the execution of the public deed which contains CEOs, terms of which will be applicable and invariable throughout the duration of the contract. Income in Chile is subject to corporate tax on an accrual basis and has a current rate of 25.5% for fiscal year 2017. The applicable and invariable corporate income tax rates of our CEOs range between 15% and 18.5%, as follows: the Fell Block is subject to a rate of 15%, the Tranquilo Block is subject to a rate of 17% and the Flamenco, Isla Norte and Campanario Blocks are subject to a rate of 18.5% for the income accrued or received during 2012 and 17% for the income accrued or received during 2013 and onward. Dividends or profits distributed to the foreign shareholders of the contractors are subject to 35% Additional Withholding Tax with a tax credit for the corporate income tax paid by the contractor. With regard to the value added tax, contractors may obtain as a refund the value added tax (which is 19% according to the Sales and Services Tax Law contained in Decree Law No. 825 of 1974) supported or paid on the import or purchase of goods or services used in connection with the exploration and exploitation activities. The applicable tax regime for each CEO remains unchanged throughout the duration of the CEOP.



The Chilean Congress approved a reform to the income tax law in September 2014 which was amended in February 2016. Under this reform the income tax rate will increase from 20% in 2013 to: 21% in 2014, 22.5% in 2015, 24% in 2016, 25.5% in 2017 and 27% in 2018. The operating subsidiaries that we control in Chile, which are GeoPark TdF S.A., GeoPark Fell S.p.A. and GeoPark Magallanes Limitada, are not affected by the income tax reform mentioned since they are covered by the tax treatment established in the CEOPs. The above has been confirmed by the Chilean IRS through ruling N°2478/2016.

## Brazil

## Regulation of the oil and gas industry

Article 177 of the Brazilian Federal Constitution of 1988 provides for the Federal Government’s monopoly over the prospecting and exploration of oil, natural gas resources and other fluid hydrocarbon deposits, as well as over the refining, importation, exportation and sea or pipeline transportation of crude oil and natural gas. Initially, paragraph one of article 177 barred the assignment or concession of any kind of involvement in the exploration of oil or natural gas deposits to private industry. On November 9, 1995, however, Constitutional Amendment Number 9 altered paragraph one of article 177 so as to allow private or state-owned companies to engage in the exploration and production of oil and natural gas, subject to the conditions to be set forth by legislation.

## Regulatory framework

## Pricing policy

Until the enactment of the Brazilian Petroleum Law, the Brazilian government regulated all aspects of the pricing of oil and oil products in Brazil, from the cost of oil imported for use in refineries to the price of refined oil products charged to the consumer. Under the rules adopted following the Brazilian Petroleum Law, the Brazilian government changed its price regulation policies. Under these regulations, the Brazilian government: (1) introduced a new methodology for determining the price of oil products designed to track prevailing international prices denominated in U.S. dollars, and (2) gradually eliminated controls on wholesale prices.

## Concessions

In addition to opening the Brazilian oil and natural gas industry to private investment, the Brazilian Petroleum Law created new institutions, including the ANP, to regulate and control activities in the sector. As part of this mandate, the ANP is responsible for licensing concession rights for the exploration, development and production of oil and natural gas in Brazil's sedimentary basins through a transparent and competitive bidding process. The ANP has conducted 14 bidding rounds for exploration concessions from 1999 through 2017. Our PN-T-597 is still subject to the entry into the concession agreement. See “—Our operations—Operations in Brazil” and “Item 3. Key information—D. Risk factors—Risks relating to our business—The PN-T-597 concession is subject to an injunction and may not close” for more information.

## Taxation

The Brazilian Petroleum Law introduced significant modifications and benefits to the taxation of oil and natural gas activities. The main component of petroleum taxation is the government take, comprised of license fees, fees payable in connection with the occupation or title of areas, royalties and a special participation fee. The introduction of the Brazilian Petroleum Law presents certain tax benefits primarily with respect to indirect taxes. Such indirect taxes are very complex and can add significantly to project costs. Direct taxes are mainly corporate income tax and social contribution on net profit.

With the effectiveness of the Brazilian Petroleum Law and the regulations promulgated by the ANP, concessionaires are required to pay the Brazilian federal government the following:

• license fees;

• rent for the occupation or retention of areas;

• special participation fee; and

• royalties on production.

The minimum value of the license fees is established in the bidding rules for the concessions, and the amount is based on the assessment of the potential, as conducted by the ANP. The license fees must be paid upon the execution of the concession contract. Additionally, concessionaires are required to pay a rental fee to landowners varying from 0.5% to 1.0% of the respective hydrocarbon production.

The special participation fee is an extraordinary charge that concessionaires must pay in the event of obtaining high production volumes and/or profitability from oil fields, according to criteria established by applicable regulation, and is payable on a quarterly basis for each field from the date on which extraordinary production occurs. This participation rate, whenever due, may reach up to 40% of net revenues depending on (i) volume of production and (ii) whether the block is onshore, shallow water or deep water. Under the Brazilian Petroleum Law and applicable regulations issued by the ANP, the special participation fee is calculated based upon quarterly net revenues of each field, which consist of gross revenues calculated using reference prices published by the ANP (reflecting international prices and the exchange rate for the period) less: royalties paid; investment in exploration; operational costs; and depreciation adjustments and applicable taxes.

The ANP is responsible for determining monthly minimum prices for petroleum produced in concessions for purposes of royalties payable with respect to production. Royalties generally correspond to a percentage ranging between 5% and 10% applied to reference prices for oil or natural gas, as established in the relevant bidding guidelines (edital de licitação) and concession agreement. In determining the percentage of royalties applicable to a particular concession, the ANP takes into consideration, among other factors, the geological risks involved and the production levels expected.



## State VAT (ICMS)

ICMS is a state sales tax. This tax is due on the local sale of oil and gas, based on the sale price, including the ICMS itself.

For intrastate transactions (carried out by a seller and a buyer located in the same Brazilian state) or imports, the ICMS rate is determined by the legislation of the state where the sale is made and generally varies from 17% to 20%. Interstate transactions (carried out between a seller and buyer located in different Brazilian states), in turn, are subject to reduced rates of 4% (if the products are imported and not submitted to a manufacturing process or, in case of further manufacturing, if the resulting product has a minimum imported content of 40%), 7% or 12%, depending on the states involved. One exception is that, due to the immunity established by the Brazilian Federal Constitution, ICMS is not due on interstate crude oil transactions when destined to industrialization and commercialization. On the other hand, in case of consumables or fixed assets, the buyer must pay to the state where the buyer is located, the ICMS DIFAL, which is calculated based on the difference between the interstate rate and the buyer's own internal ICMS rate.

ICMS is calculated under the noncumulative regime, and therefore some input transactions could result in tax credits (for example the acquisition of inputs and fixed assets directly used in the company’s activity).

## Social contribution taxes on gross revenue (PIS and COFINS)

PIS and COFINS are social contribution taxes charged on gross revenues earned by a Brazilian Federal Revenue noncumulative regime of calculation.

Under the noncumulative regime, PIS and COFINS are generally charged at a combined nominal rate of 9.25% (1.65% PIS and 7.6% COFINS) on national revenues earned by a legal entity. In that case, certain business costs result in tax credits to offset PIS and COFINS liabilities (e.g., input and services acquisitions, expenses of depreciation and amortization of machinery, equipment and other fixed assets acquired to be directly used in the company's activities). PIS and COFINS paid upon the importation of certain inputs, assets and services contracted that are destined to the company's activity are also creditable. Although upstream industries are generally subject to this regime, it is not clear yet when this benefit is applied according to the stage of the field, (exploration or production).

Since July 1, 2015, taxpayers subject to the noncumulative regime must calculate PIS and COFINS over certain financial revenues, applying rates of 0.65% and 4%, respectively.

## Federal Industrialization VAT (IPI) and Municipality VAT (ISS)

IPI is a non-cumulative tax and may be due on goods acquisitions by importation or national transactions. The IPI rate will be applied depending on the NCM classification of the product according to TIPI (Table of IPI). On the acquisition of local goods subject to IPI, such tax is included in the price of the good. Considering that O&G activity (upstream) is not subject to IPI taxation, the amount of the tax cannot be considered as a credit (even though IPI is under the non-cumulative regime applicable for IPI's taxpayers), which means that this will be a cost for the legal entity acquirer. In relation to the importation, the importer of record will be considered as the taxpayer and will be obliged to pay the IPI due on the transaction. For the same aforementioned reasons for the O&G companies (upstream), this will be considered as cost when the importation is subject to IPI.

ISS is a cumulative tax which is due on provided services and imported services. Usually, regarding local transactions, such tax is included in the price of the service charged by the service provider. In relation to the import of service, the Brazilian entity contractor is responsible for the payment of the ISS, which means that, depending on contractual arrangement, the tax burden may be supported by the Brazilian contractor or the foreign service provider.

ISS tax rate may vary from 2% to 5% and will depend on the nature of service, as well as where the service provider is located (in general, some exceptions may apply).

Additionally, GeoPark Brazil was granted in 2018 a tax benefit issued by SUDENE (Northeastern Development Superintendence), by means of the Constitutive Act No. 0069/2018, which approved the tax incentive to reduce by 75% the Income Tax and Additions, calculated over the company exploration profits, based on Article 1 of the Provisory Measure 2,199-14 of August 24, 2001, in accordance with the requirements established by the Decree 6,539 of August 18, 2008.

The benefit will be valid for 10 years, starting from January 1, 2018, under the condition of modernizing the entire project on the SUDENE operating area, observing all provided legal conditions and requirements that includes compliance with labor and social law and with all environmental protection and control regulations, annual submission of a declaration of income and a restriction to the distribution to partners or shareholders of the tax amount which is not payed due to the tax exemption.

The noncompliance with the requirements provided constitutes a default of the beneficiary company in respect to SUDENE and shall be subject to the applicable penalties.

## Peru

## Regulation of the oil and gas industry

The hydrocarbons activities in Peru are mainly regulated by the General Hydrocarbons Law (Law 26,221), and several regulations enacted in order to develop the provisions included in such law.

According to the Hydrocarbons Law, oil and gas exploration and production activities are carried out under license or service contracts granted by the government. Under a license contract, the investor pays a royalty, whereas under a service contract, the government pays remuneration to the contractor. As stated by the Peruvian Constitution and the Organic Law for Hydrocarbons,



a license contract does not imply a transfer or lease of property over the area of exploration or exploitation. By virtue of the license contract, the contractor acquires the authorization to explore or to exploit hydrocarbons in a determined area, and Perupetro (the entity that holds the Peruvian state interest) transfers the property right in the extracted hydrocarbons to the contractor, who must pay a royalty to the state.

## Regulatory framework

License and service contracts are approved by a supreme decree issued by the Peruvian Ministry of Economy and Finance, and the Peruvian Ministry of Energy and Mining, and can only be modified by a written agreement signed by the parties. Before initiating any negotiation, every oil and gas company must be duly qualified by Perupetro, in order to determine if it fulfills all the requirements needed to develop exploration and production activities under the contract form requirements mentioned above.

License and services agreements may be granted for just an exploitation stage -when a commercial discovery has been made- or for an exploration and exploitation stage -when such discovery has not been made yet. In this case, the exploration phase will last no more than 7 years, counted from the effective date of the contract (60 days after the signing date). This term can be divided into several periods as agreed in the contract, and all of them with a minimum work obligation that should be fulfilled by a contractor in order to access the next exploration period. The exploration phase will last until a declaration of commercial discovery is made by the contractor. The exploitation phase will last from the date of such declaration until 30 years from the date of the contract.

The Ministry of Energy and Mines may exceptionally authorize an extension of three years for the exploration stage, if the contractor has fulfilled with the minimum work program established in the contract, and also commits to fulfill an additional work program that justifies such extension. The contractor shall be responsible for providing the technical and economic resources required for the execution of the operations of this phase.

The Peruvian regulations also established the roles of the Peruvian government agencies that regulate, promote and supervise the oil and gas industry, including the Ministry of Energy and Mines, Perupetro and OSINERGMIN.

## Taxation

The fiscal regime that applies in Peru to the oil and gas industry consists of a combination of corporate income tax, royalties and other levies.

In general terms, oil and gas companies are subject to the general corporate income tax regime that is stabilized in the applicable regime on the date of subscription of the original License Agreement (due to a tax stability contract); nevertheless, there are certain special tax provisions for the oil and gas sector (the approval of the new Organic Hydrocarbons Law is pending in order to encourage investments in license agreements that are already operating in Peru and to promote exploration; as well as defining what will be the treatment on VAT in hydrocarbon exploration projects). At the end of 2018, the Congress approved to extend the VAT refund to this type of projects to December 2019.

The stabilized income tax regime will only cover the activities of the License Agreement (exploration and/or exploitation activities), therefore, the related activities (i.e., activities related to oil and gas, but not carried out under the terms of the contract) and other activities (i.e., activities not related to oil and gas) will be governed by the income tax rules in force to date.

Resident companies (incorporated in Peru), are subject to income tax on their worldwide taxable income. Branches and permanent establishments of foreign companies that are located in Peru and non-resident entities are taxed on Peruvian source income only.

With respect to the Morona Agreement, in which we take part, the applicable income tax stabilized regime is from 1995, which is the year of subscription of the original License Agreement. The income tax rate in 1995 was 30% and there was no withholding income tax for dividends. Additionally, in 1995 it was stated that the income tax should not be lower than 2% of the net assets of the Company (the “Minimum Income Tax”). The Minimum Income Tax was later declared unconstitutional, which is why, even when there was a tax stability contract, the Minimum Income Tax has been understood as not applicable or enforceable.

Taxable income is generally computed by reducing gross revenue by cost of goods sold and all expenses necessary to produce the income or maintain the source of income. Certain types of revenue, however, must be computed as specified in the tax law and some expenses are not fully deductible for tax purposes. Business transactions must be recorded in legally authorized accounting records that are in full compliance with the International Accounting Standards (IAS). Contractors in a license or services contract for the exploration or exploitation of hydrocarbons (Peruvian corporations and branches) are entitled to keep their accounting records in foreign currency, but taxes must be paid in Peruvian Soles (“PEN”).

Any investments in a contract area that did not reach the commercial extraction stage and that were totally released, can be accumulated with the same type of investments made in another contract area that has reached the stage of commercial extraction.

These investments are amortized in accordance with the amortization method chosen by the contractor. If the contractor has entered into a single contract, the accumulated investments are charged as a loss against the results of the contract for the year of total release of the area for any contract that did not reach the commercial extraction stage, with the exception of investments consisting of buildings, power installations, camps, means of communication, equipment and other goods that the contractor keeps or recovers to use in the



same operations or in other operations of a different nature.
The contractor determines the tax base and the amount of the tax, separately and for each contract. If the contractor carries out related activities or other activities, the contractor is obligated to determine the tax base and the amount of tax, separately, and for each activity. The corresponding tax is determined based on the income tax provisions that apply in each case (subject to the tax stability provisions for contract activities and based on the regular regime for the related activities or other activities). The total income tax amount that the contractor must pay is the sum of the amounts calculated for each contract, for both the related activities and for the other activities. The forms to be used for tax statements and payments are determined by the tax administration. If the contractor has more than one contract, it may offset the tax losses generated by one or more contracts against the profits resulting from other contracts or related activities. Moreover, the tax losses resulting from related activities may be offset against the profits from one or more contracts.

It is possible to choose the allocation of tax losses to one or more of the contracts or related activities that have generated the profits, provided that the losses are depleted or compensated to the limit of the profits available. This means that if there is another contract or related activity, the taxpayer can continue compensating tax losses until they are completely offset. A contractor with tax losses from one or more contracts or related activities may not offset them against profits generated by the other activities. Furthermore, in no case may tax losses generated by the other activities be offset against the profits resulting from the contracts or the related activities.

During the exploration phase, operators are exempt from import duties and other forms of taxation applicable to goods intended for exploration activities. Exemptions are withdrawn at the production phase, but exceptions are made in certain instances, and the operator may be entitled to temporarily import goods tax-free for a two-year period (“Temporary Import”). A temporary Import may be extended for additional one year periods for up to two times upon the request of an operator, approval of the Ministry of Energy and Mines and authorization of the Superintendencia Nacional de Aduanas y de Administracion Tributaria (Peruvian Customs Agency).

Several Legislative Decrees were published on September 13, 2018, introducing modifications to the Income Tax Law and the Tax Code.

Income Tax Law: These dispositions are effective since January 1, 2019.
• Legislative Decree 1369 allows companies to deduct the payment for technical assistance, assignment in use and other services provided by non-domiciled in the fiscal year that the service is paid, as long as the payment be made before the deadline for submitting the corresponding Income Tax Affidavit.

Additionally, new transfer pricing rules were established: (i) the obligations to apply the benefit test is now only applicable to operations between related parties and no longer to operations with, towards or through tax havens; and (ii) the “cost+expense+mark up” structure to deduct the expenses for services between related parties will now only be applicable to low added value services, and not to entirety of services between related parties.

• Legislative Decree 1381 updates the concept of tax havens to include “non-cooperative” countries or countries that have a “preferential regime”. The law has established a criterion to qualify a country under this concept.

In addition, when applying the Comparable Uncontrolled Price (CUP) method to cross-border transactions involving commodities, the Legislative Decree establishes that the arm’s-length price for Peruvian income tax purposes must be determined by reference to a publicly quoted price. The actual pricing date or period of pricing dates should be used as a reference to determine the price for the transaction, as long as independent parties in comparable circumstances would have relied upon the same pricing date. The taxpayer needs to notify the SUNAT (i.e., Peruvian Tax Authority) of the actual pricing date or period of pricing dates used to determine the price for the transaction.

Legislative Decree 1424 extends the application of sub capitalization rules (maximum deductible interest determination) to unrelated parties.

Likewise, as of 2021, the interest generated in transactions with related or unrelated parties that exceeds 30% of EBITDA of the preceding year will not be deductible. Interest that is not deducted may be carried forward for up to four years.

On the other hand, this Legislative Decree introduces in the Income Tax Law scenarios in which Permanent Establishments are triggered.

Additionally, other provisions have been included in this Legislative Decree, for instance, that an indirect transfer of Peruvian shares will always be triggered if the amount paid for the shares of a non-resident entity that corresponds to the Peruvian shares is equivalent to or higher than 40,000 Tax Units (approximately US$ 50.3 million).

• Legislative Decree 1425 establishes a general and specific rules to determine when to consider income or expenses as “accrued”.

## Tax Code:

• Legislative Decree 1422 includes provisions for the implementation of the General Anti-Avoidance Rule (GAAR) and will be applicable to facts, acts and situations from July 19, 2012 onwards and even to tax audits already started.

In case of entities with a Board of Directors, that Board of Directors will be responsible of approving the tax planning of the entity. That obligation cannot be delegated. The Board of Directors must evaluate the tax planning strategies implemented up to September 14, 2018 in order to ratify or modify them. The term for ratify or modify them will end on March 29, 2019.



• Legislative Decree 1372 establishes the obligation for legal entities resident in Peru to identify, obtain, update, report on the identification of their final beneficiaries, maintain that information and present a declaration to the Tax Authority that provides the information that includes the chain of ownership or control, the percentage ownership, among others. This Legislative Decree is effective since August 03, 2018, and the Resolution that establishes the deadlines for submitting the informative affidavit of final beneficiary is still pending.

In May 2018, GeoPark Perú SAC applied for a VAT anticipated refund regime that will allow it to recover the tax paid until the first oil is produced. The regime is established by Legislative Decree 973, which demands a minimum investment of US$5.0 million, and a preoperative period of 2 years (which for Morona Block starts on December 2016).

## Environmental Regulation

Before initiating any hydrocarbon activity (e.g. seismic exploration, drilling of exploration wells, etc.) the contractor must file and obtain an approval for an Environmental Impact Study (EIS), which is the most important permit related to HSE for any hydrocarbon project. This study includes technical, environmental and social evaluations of the project to be executed in order to define the activities that should be required for preventing, minimizing, mitigating and remediation of the possible negative environmental and social impacts that the hydrocarbon project may generate.

There are general environmental regulations for the protection of water, soils, air, endangered species, biodiversity, natural protected areas, etc. In addition, there are specific environmental regulations applicable to the hydrocarbon industry.

## Argentina

## Regulatory framework

From the 1920s to 1989, the Argentine public sector dominated the upstream segment of the Argentine oil and gas industry and the midstream and downstream segment of the business.

The Hydrocarbon Law No. 17,319 enacted in 1967 continues in force until today, subject to amendments introduced by the Deregulation Decrees and Laws No. 24,145, 26,197 and 27,007.

The Hydrocarbon Law No. 17,319 provided for the existence of a state-owned oil & gas company (originally, YPF) for whom private companies served as service contractors or joint venture partners. But it also provided for a concession & royalty system which in practice was not used until after the YPF privatization.

In 1989, Argentina enacted certain laws aimed at privatizing the majority of its state-owned companies and issued a series of presidential decrees (namely, Decrees No. 1055/89, 1212/89 and 1589/89 (the "Oil Deregulation Decrees"), relating specifically to deregulation of energy activities). The Oil Deregulation Decrees eliminated restrictions on imports and exports of crude oil, deregulated the domestic oil industry, and effective January 1, 1991, the prices of oil and petroleum products were also deregulated. In 1992, Law No. 24,145, referred to as the Privatization Law, privatized YPF and provided for transfer of hydrocarbon reservoirs from the Argentine government to the provinces, subject to the existing rights of the holders of exploration permits and production concessions.

In October 2004, the Argentine Congress enacted Law No. 25,943, creating a new state-owned energy company, Energía Argentina S.A. ("ENARSA"). The corporate purpose of ENARSA was initially the exploration and exploitation of solid, liquid and gaseous hydrocarbons; the transport, storage, distribution, commercialization and industrialization of these products; as well as the transportation and distribution of natural gas, and the generation, transportation, distribution and sale of electricity. Moreover, Law No. 25,943 granted ENARSA all offshore areas located beyond 12 nautical miles from the coastline up to the outer boundary of the continental shelf that were vacant at the time of the effectiveness of this law (i.e. November 3, 2004). In 2014, all open acreage offshore exploration permits and exploitation concessions were conveyed to the National Energy Secretary (NSE) and all existing JV agreements entered into by ENARSA with private investors were conveyed by ENARSA to YPF in accordance with Section 30, New Hydrocarbons Act No. 27,007.

On May 3, 2012, the Argentine Congress passed the Hydrocarbons Sovereignty Act. This law declared achieving self-sufficiency in the supply of hydrocarbons, as well as in the exploitation, industrialization, transportation and sale of hydrocarbons, a national public interest and a priority for Argentina. In addition, the law expropriated 51% of the share capital of YPF, the largest Argentine oil company, from Repsol, the largest Spanish oil company.

On July 28, 2012, Presidential Decree 1277/2012, which regulated the Hydrocarbon Sovereignty Law, was released, creating a Strategic Planning and Coordination Committee for the National Hydrocarbon Investment Plan and vesting it with the power to set the sector's reference prices and to develop investment plans for the country to increase production and reserves. The decree introduced important changes to the rules governing Argentina's oil and gas industry, including the repeal of certain articles of Deregulation Decrees passed during 1989 relating to free marketability of hydrocarbons at negotiated prices, the deregulation of the oil and gas industry, freedom to import and export hydrocarbons and the ability to keep proceeds from export sales in foreign bank accounts.

On January 4, 2016, immediately after the new national administration took office, Presidential Decree 272/2015 was released. This Decree abrogated the provisions of the Presidential Decree 1277/2012 which had repealed the Deregulation Decrees. Thus, the Deregulation Decrees were reinstated.

Other measures have also been taken by the new presidential administration



aimed at reducing government intervention and reestablishing market forces in the oil & gas industry:

• Effective October 1 2017 both domestic oil prices at the wellhead and gasoline prices at the dispenser were allowed to float freely, ending floor pricing schemes sheltering the oil producers during low oil times.

• Also, effective October 22, 2018, Resolution 103/2018 established a new framework governing natural gas export authorization proceedings, including long term and short-term firm export authorizations, interruptible export authorizations, summer export authorizations and operational exchanges. These new natural gas exports were soon put in practice and natural gas exports by pipeline to neighbouring countries resumed in 2018.

## Domain and Jurisdiction of hydrocarbons resources

After a constitutional reform enacted in 1994, eminent domain over hydrocarbon resources lying in the territory of a provincial state is now vested in such provincial state, while eminent domain over hydrocarbon resources lying offshore on the continental platform beyond the jurisdiction of the coastal provincial states is vested in the federal state.

Thus, oil and gas exploration permits and exploitation concessions are now granted by each provincial government. A majority of the existing concessions were granted by the federal government prior to the enactment of Law No.26,197 and were thereafter transferred to the provincial states.

## Hydrocarbon Exports and Self Sufficiency

Achieving self-sufficiency has been an energy policy goal from the early days of the industry.

Section 6 of the Hydrocarbon Law No. 17,319 allows the National Executive Branch to authorize the export of hydrocarbons. At times when the domestic production of liquid hydrocarbons is insufficient to cover domestic needs, the delivery of the entire availability of such locally produced hydrocarbons to the domestic market shall be mandatory, with such exceptions as may be justified on technical grounds.

In turn, Section 3 of the Natural Gas Regulatory Framework 24,076 allows the National Executive Branch to authorize the export of natural gas. The granting of natural gas export permits is regulated in detail.

Supply privileges favouring the domestic market to the detriment of the export market, including hydrocarbon export restrictions, domestic price controls, export duties and domestic market supply obligations have been implemented several times.

## Regulation of exploration and production activities

New Hydrocarbon Act:

In October 31, 2014 the Argentine Republic Official Gazette published the text of Law No. 27,007, amending the Hydrocarbon Law No. 17,319.

The most relevant aspects of the new law are as follows:

• With regards to concessions, three types of concessions are provided, namely, conventional exploitation, unconventional exploitation, and exploitation in the continental shelf and territorial waters, establishing the respective terms for each type.

• The terms for hydrocarbon transportation concessions were adjusted in order to comply with the exploitation concessions terms.

• With regards to royalties, a maximum of 12% is established, which may reach 18% in the case of granted extensions, where the law also establishes the payment of an extension bond for a maximum amount equal to the amount resulting from multiplying the remaining proven reserves at the end of effective term of the concession by 2% of the average basin price applicable to the respective hydrocarbons over the 2 years preceding the time on which the extension was granted.

• The extension of the Investment Promotion Regime for the Exploitation of Hydrocarbons (Decree No. 929/2013) is established for projects representing a direct investment in foreign currency of at least 250 million dollars, increasing the benefits for other type of projects.

## Regulation of transportation activities

Exploitation concessionaires have the exclusive right to obtain a transportation concession for the transport of oil and gas from the provincial states or the federal government, depending on the applicable jurisdiction. Such transportation concessions include storage, ports, pipelines and other fixed facilities necessary for the transportation of oil, gas and by-products. Transportation facilities with surplus capacity must transport third parties' hydrocarbons on an open-access basis, for a fee which is the same for all users on similar terms. As a result of the privatizations of YPF and Gas del Estado, a few common carriers of crude oil and natural gas were chartered and continue to operate to date.

Effective February 8, 2019, to promote transportation capacity expansions, Decree 115/2019 allowed interested shippers to reserve transportation capacity in new or expanded pipelines through freely negotiated capacity reservation agreements.

## Taxation

Exploitation concessionaires are subject to the general federal and provincial tax regime. The most relevant federal taxes are the income tax (30%), the value added tax (21%) and a tax on assets. The most relevant provincial taxes are the turnover tax (3% on average) and stamp tax.

Tax reform was enacted in Argentina in December 2017. The legislation included significant changes to certain corporate income tax and statutory income tax provisions, including rate reductions. Most of the tax provisions were effective as of the beginning of fiscal year 2018.

With this tax reform, the corporate income tax, which was previously 35% has the following rate schedule:

• 30% in 2018 and 2019



• 25% in 2020 and 2021 and onwards.

Other changes include the following:

- New withholding tax on dividends—with the applicable rates for non-resident shareholders of: (1) 7% for dividends distributed out of the distributing entity’s previously taxed profits of fiscal years 2018 and 2019; and (2) 13% for dividends distributed out of the distributing entity’s previously taxed profits of fiscal years 2020 and onwards.

• Application of inflation adjustment for corporate tax purposes is reinstated under certain circumstances (e.g. if the inflation cumulative rate for three consecutive years exceeds 100%).

• Possible tax revaluation of investment in fixed assets, under payment of a special tax.

• Certain restrictions for the deduction of exchange differences on income tax.

• New export taxes applicable to services activities.

• Allow for short term recovery of VAT paid on acquisitions or imports of capital goods, when non-recoverable with VAT on usual sales.

## C. Organizational structure

We are an exempted company incorporated pursuant to the laws of Bermuda. We operate and own our assets directly and indirectly through a number of subsidiaries. See an illustration of our corporate structure in Note 21 (“Subsidiary undertakings”) to our Consolidated Financial Statements. During 2017, we decided to incorporate a subsidiary in the United Kingdom (international investor centre) to conduct our businesses and financial decisions.

## D. Property, plant and equipment

See “—B. Business Overview—Title to properties.”

## ITEM 4A. UNRESOLVED STAFF COMMENTS

Not applicable.

## ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

## A. Operating results

The following discussion of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and the notes thereto as well as the information presented under “Item 3. Key Information—A. Selected financial data.”

The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those discussed in the forward-looking statements as a result of various factors, including those set forth in “Item 3. Key Information—D. Risk factors” and “Forward-looking statements.”

## Factors affecting our results of operations

We describe below the year-to-year comparisons of our historical results and the analysis of our financial condition. Our future results could differ materially from our historical results due to a variety of factors, including the following:

## Discovery and exploitation of reserves

Our results of operations depend on our level of success in finding, acquiring (including through bidding rounds) or gaining access to oil and natural gas reserves. While we have geological reports evaluating certain proved, contingent and prospective resources in our blocks, there is no assurance that we will continue to be successful in the exploration, appraisal, development and commercial production of oil and natural gas. The calculation of our geological and petrophysical estimates is complex and imprecise, and it is possible that our future exploration will not result in additional discoveries, and, even if we are able to successfully make such discoveries, there is no certainty that the discoveries will be commercially viable to produce.

For the year ended December 31, 2018, we made total capital expenditures of US$ 124.7 million (US$97.0 million, US$7.9 million, US$9.0 million, US$8.5 million and US$2.3 million in Colombia, Chile, Argentina, Peru and Brazil, respectively), consisting of US$43.5 million related to exploration.

Oil prices were volatile since the end of 2014. In preparation for continued volatility, we have developed multiple scenarios for our 2019 capital expenditure program. See “Item 4. Information on the Company –B. Business Overview—2019 Strategy and Outlook.”

Funding for our capital expenditures relies in part on oil prices remaining close to our estimates or higher levels and other factors to generate sufficient cash flow. Low oil prices affect our revenues, which in turn affect our debt capacity and the covenants in our financing agreements, as well as the amount of cash we can borrow using our oil reserves as collateral, the amount of cash we are able to generate from current operations and the amount of cash we can obtain from prepayment agreements such as the Trafigura Agreement, which is our offtake and prepayment agreement. If we are not able to generate the sales which, together with our current cash resources, are sufficient to fund our capital program, we will not be able to efficiently execute our work program which would cause us to further decrease our work program, which could harm our business outlook, investor confidence and our share price.

If oil prices average higher than the base budget price, we have the ability to allocate additional capital to more projects and increase its work and investment program and thereby further increase oil and gas production.

Our results of operations will be adversely affected in the event that our estimated oil and natural gas asset base does not result in additional reserves that may eventually be commercially developed. In addition, there can be no assurance that we will acquire new exploration blocks or gain access to exploration blocks that contain reserves. Unless we succeed in exploration and



development activities, or acquire properties that contain new reserves, our anticipated reserves will continually decrease, which would have a material adverse effect on our business, results of operations and financial condition.

## Oil and gas revenue and international prices

Our revenues are derived from the sale of our oil and natural gas production, as well as of condensate derived from the production of natural gas. The price realized for the oil we produce is generally linked to Brent or Vasconia. The price realized for the natural gas we produce in Chile is linked to the international price of methanol, which is settled in the international markets in US$. The market price of these commodities is subject to significant fluctuation and has historically fluctuated widely in response to relatively minor changes in the global supply and demand for oil and natural gas, market uncertainty, economic conditions and a variety of additional factors.

From January 1, 2014 to December 31, 2018, Brent spot prices ranged from a low of US$27.9 per barrel to a high of US$118.9 per barrel, Henry Hub natural gas average spot prices ranged from a low of US$1.7 per mmbtu to a high of US$6.0 per mmbtu, US Gulf methanol spot barge prices ranged from a low of US$250.0 per metric ton to a high of US$635.1 per metric ton. Furthermore, oil, natural gas and methanol prices do not necessarily fluctuate in direct relationship to each other.

As a consequence of the oil price crisis which started in the second half of 2014 (WTI and Brent, the main international oil price benchmarks, fell more than 60% between October 2014 and February 2016), we took decisive steps in 2015 and 2016 to adapt to the new oil price environment. We reduced our capital expenditure program from US$238 million in 2014 to US$48 million in 2015 and US$39 million in 2016 and implemented significant cost reduction initiatives that resulted in production and operating costs being reduced by 49% (2016 versus 2014), and administrative expenses being reduced by 26% (2016 versus 2014), while increasing average production to approximately 22.4 mboepd and increasing our proved reserves to 73.6 mmboe.

In October 2016, we decided to manage part of our exposure to the volatile crude oil price using derivatives. For further information related to Commodity Risk Management Contracts, please see Note 8 to our Consolidated Financial Statements.

Additionally, the oil and gas we sell may be subject to certain discounts. For example, in Colombia, the price of oil we sell is based on Vasconia, a marker broadly used in the Llanos Basin, adjusted for certain marketing and quality discounts based on, among other things, API, viscosity, sulfur, delivery point and water content, as well as on certain transportation costs (including pipeline costs and trucking costs).

In Chile, the price of oil we sell to ENAP is based on Brent minus certain marketing and quality discounts. We have a long-term gas supply contract with Methanex. The price of the gas sold under this contract is determined based on a formula that takes into account various international prices of methanol, including US Gulf methanol spot barge prices, methanol spot Rotterdam prices and spot prices in Asia. See “Item 3. Key Information—D. Risk factors—Risks relating to our business—A substantial or extended decline in oil, natural gas and methanol prices may materially adversely affect our business, financial condition or results of operations.”

In Brazil, prices for gas produced in the Manati Field are based on a long-term off-take contract with Petrobras. The price of gas sold under this contract is denominated in reais and is adjusted annually for inflation pursuant to the Brazilian General Market Price Index (Índice Geral de Preços—Mercado) (the “IGPM”). See Note 3 to our Consolidated Financial Statements.

In Argentina, the realized oil prices for our production in the Neuquén Basin follows the “Medanito” blend oil price reference, which has traditionally been linked to ICE Brent adjusted by certain marketing and quality discounts based on API, delivery point and transport costs. Between May and November 2018, Medanito crude prices were capped industry-wide between US$ 65 per barrel and US$ 70 per barrel. Since December 2018, domestic prices have reconnected to the international benchmark.

Gas sales in Argentina are carried out through annual contracts that go from May to April. The price of the gas sold under these contracts depends mainly on domestic supply and demand and regulation affecting the sector.

If the market prices of oil and methanol had fallen by 10% as compared to actual prices during the year, with all other variables held constant, and taking into account the impact of the derivative contracts in place, post-tax profit for the year ended December 31, 2018 would have been lower by US$13.7 million (post-tax loss would have been higher by US$10.4 million in 2017).

## Production and operating costs

Our production and operating costs consist primarily of expenses associated with the production of oil and gas, the most significant of which are gas plant leasing, facilities and wells maintenance (including pulling works), labor costs, contractor and consultant fees, chemical analysis, royalties and products, among others. As commodity prices increase or decrease, our production costs may vary. We have historically not hedged our costs to protect against fluctuations.

## Availability and reliability of infrastructure

Our business depends on the availability and reliability of operating and transportation infrastructure in the areas in which we operate. Prices and availability for equipment and infrastructure, and the maintenance thereof, affect our ability to make the investments necessary to operate our business, and thus our results of operations and financial condition. See “Item 3. Key Information—D. Risk factors—Risks relating to our business—Our inability to access needed equipment and infrastructure in a timely manner may hinder our access to oil and natural gas markets and generate significant incremental costs or delays in our oil and natural gas production.”



## Production levels

Our oil and gas production levels are heavily influenced by our drilling results, our acquisitions and to oil and natural gas prices.

We expect that fluctuations in our financial condition and results of operations will be driven by the rate at which production volumes from our wells decline. As initial reservoir pressures are depleted, oil and gas production from a given well will decline over time. See “Item 3. Key Information—D. Risk factors—Risks relating to our business—Unless we replace our oil and natural gas reserves, our reserves and production will decline over time. Our business is dependent on our continued successful identification of productive fields and prospects and the identified locations in which we drill in the future may not yield oil or natural gas in commercial quantities.”

## Contractual obligations

In order to protect our exploration and production rights in our licensed areas, we must make and declare discoveries within certain time periods specified in our various special contracts, E&P Contracts and concession agreements. The costs to maintain or operate our licensed areas may fluctuate or increase significantly, and we may not be able to meet our commitments under these agreements on commercially reasonable terms or at all, which may force us to forfeit our interests in such areas. If we do not succeed in renewing these agreements, or in securing new ones, our ability to grow our business may be materially impaired. See “Item 3. Key Information—D. Risk factors—Risks relating to our business—Under the terms of some of our various CEOs, E&P Contracts and concession agreements, we are obligated to drill wells, declare any discoveries and file periodic reports in order to retain our rights and establish development areas. Failure to meet these obligations may result in the loss of our interests in the undeveloped parts of our blocks or concessioned areas.”

## Acquisitions

As described above, part of our strategy is to acquire and consolidate assets in Latin America. We intend to continue to selectively acquire companies, producing properties and concessions. As with our historical acquisitions, any future acquisitions could make year-to-year comparisons of our results of operations difficult. We may also incur additional debt, issue equity securities or use other funding sources to fund future acquisitions. We generally incorporate our acquired business into our results of operations at or around the date of closing.

## Functional and presentational currency

Our Consolidated Financial Statements are presented in US$, which is our presentational currency. Items included in the financial information of each of our entities are measured using the currency of the primary economic environment in which the entity operates, or the functional currency, which is the US$ in each case, except for our Brazil operations, where the functional currency is the real.

## Geographical segment reporting

In the description of our results of operations that follow, our “Other” operations reflect our non-Colombian, non-Chilean, non-Argentine and non-Brazilian operations, primarily consisting of our corporate head office operations.

We divide our business into five geographical segments—Colombia, Chile, Brazil, Argentina and Peru—that correspond to our principal jurisdictions of operation. Activities not falling into these five geographical segments are reported under a separate corporate segment that primarily includes certain corporate administrative costs not attributable to another segment.

## Description of principal line items

The following is a brief description of the principal line items of our statement of income.

## Revenue

Revenue includes the sale of crude oil, condensate and natural gas net of value-added tax (“VAT”), and discounts related to the sale (such as API and mercury adjustments) and overriding royalties due to the ex-owners of oil and gas properties where the royalty arrangements represent a retained working interest in the property. Revenue is recognized when control has been transferred to the purchaser and if revenue can be measured reliably and is expected to be received.

## Commodity risk management contracts

Includes realized and unrealized gains and losses arising from commodity risk management contracts.

## Production and operating costs

Production and operating costs are recognized on the accrual basis of accounting. These costs include wages and salaries incurred to achieve the revenue for the year. Direct and indirect costs of raw materials and consumables, rentals, leasing and royalties are also included within this account. For a description of our production and operating costs, see “—Factors affecting our results of operations.”

## Depreciation and write-off of unsuccessful efforts

Capitalized costs of proved oil and natural gas properties are depreciated on a licensed-area-by-licensed-area basis, using the unit of production method, based on commercial proved and probable reserves as calculated under the Petroleum Resources Management System methodology promulgated by the Society of Petroleum Engineers and the World Petroleum Council (the “PRMS”), which differs from SEC reporting guidelines pursuant to which certain information in the forepart of this annual report is presented. The calculation of the “unit of production” depreciation takes into account estimated future discovery and development costs. Changes in reserves and cost estimates are recognized prospectively. Reserves are converted to equivalent units on the basis of approximate relative energy content.



In particular, upon completion of the evaluation phase, a prospect is either transferred to oil and gas properties if it contains reserves or is charged to profit and loss in the period in which the determination is made. See “—Critical accounting policies and estimates—Oil and gas accounting.”

## Geological and geophysical expenses

Geological and geophysical expenses are recognized on the accrual basis of accounting and consist of geosciences costs, including wages and salaries and share-based compensation not subject to capitalization, geological consultancy costs and costs relating to independent reservoir engineer studies.

## Administrative expenses

Administrative expenses are recognized on the accrual basis of accounting and consist of corporate costs such as director fees and travel expenses, new project evaluations and back-office expenses principally comprised of wages and salaries, share-based compensation, consultant fees and other administrative costs, including certain costs relating to acquisitions.

Our administrative expenses for the year ended December 31, 2018 increased by US$10.0 million, or 24%, compared to the year ended December 31, 2017 mainly due to higher staff costs resulting from increased scale of operations. However, administrative costs may increase as a result of our Peruvian and Argentinian operations, other acquisitions, increased activity or the impact of appreciation of local currencies in the countries where we operate.

## Selling expenses

Selling expenses are recognized on the accrual basis of accounting and consist primarily of transportation, storage costs and selling taxes.

## Impairment of non-financial assets

Assets that are not subject to depreciation and/or amortization (such as exploration and evaluation assets) are tested annually for impairment. Assets that are subject to depreciation and/or amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value minus costs to sell and value in use.

During 2018 we recognized a net reversal of impairment losses of US$5.0 million, while in 2017 we did not recognize or reverse any impairment losses and in 2016 we recognized a reversal of impairment losses of US$5.7 million. See Note 36 to our Consolidated Financial Statements.

## Financial costs

Financial results include interest expenses, interest income, bank charges, the amortization of financial assets and liabilities, and foreign exchange gains and losses.
Profit or loss for the period attributable to owners of the Company
Profit or loss for the period attributable to owners of the Company consists of profit or losses for the year less non-controlling interest.

## Critical accounting policies and estimates

We prepare our Consolidated Financial Statements in accordance with IFRS and the interpretations of the IFRS Interpretations Committee ("IFRIC"), as adopted by the IASB. The preparation of the financial statements requires us to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experience and various other assumptions that we believe to be reasonable under the circumstances. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from those estimates.

An accounting policy is considered critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time such estimate is made, and if different accounting estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. We believe that the following accounting policies represent critical accounting policies as they involve a higher degree of judgment and complexity in their application and require us to make significant accounting estimates. The following descriptions of critical accounting policies and estimates should be read in conjunction with our Consolidated Financial Statements and the accompanying notes and other disclosures.

## Business combinations

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the fair market value of the assets acquired, equity instruments issued and liabilities incurred or assumed on the date of completion of the acquisition. Acquisition costs incurred are recognized directly in the consolidated statement of income. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair market values at the acquisition date. The excess of the cost of acquisitions over fair market value of a company's share of the identifiable net assets acquired is recorded as goodwill. If the cost of the acquisition is less than a company's share of the net assets acquired, the difference is recognized directly in the consolidated statement of income.

The determination of fair value of identifiable acquired assets and assumed liabilities means that we are to make estimates and use valuation techniques, including independent appraisers. The valuation assumptions underlying each of these valuation methods are based on available updated information, including discount rates, estimated cash flows, market risk rates and other



data. As a result, the process of identification and the related determination of fair values require complex judgments and significant estimates.

## Cash flow estimates for impairment assessments

Cash flow estimates for impairment assessments require assumptions about two primary elements: future prices and reserves. Estimates of future prices require significant judgments about highly uncertain future events. Historically, oil and natural gas prices have exhibited significant volatility. Our forecasts for oil and natural gas revenues are based on prices derived from future price forecasts among industry analysts, as well as our own assessments. Estimates of future cash flows are generally based on assumptions of long-term prices and operating and development costs.

The process of estimating reserves requires significant judgments and decisions based on available geological, geophysical, engineering and economic data. The estimation of economically recoverable oil and natural gas reserves and related future net cash flows was performed based on the D&M Reserves Report. Such estimates incorporate many factors and assumptions including:

• expected reservoir characteristics based on geological, geophysical and engineering assessments;

• future production rates based on historical performance and expected future operating and investment activities;

• future oil and natural gas prices and quality differentials;

• anticipated effects of regulation by governmental agencies; and

• future development and operating costs.

Our management believes these factors and assumptions are reasonable based on the information available at the time we prepare our estimates. However, these estimates may change substantially as additional data from ongoing development activities and production performance becomes available and as economic conditions impacting oil and natural gas prices and costs change.

For further information related to impairment of property, plant and equipment, please see Note 36 to our Consolidated Financial Statements.

## Oil and gas accounting

Oil and gas exploration and production activities are accounted for in accordance with the successful efforts method on a field by field basis. We account for exploration and evaluation activities in accordance with IFRS 6, Exploration for and Evaluation of Mineral Resources, capitalizing exploration and evaluation costs until such time as the economic viability of producing the underlying resources is determined. Costs incurred prior to obtaining legal rights to explore are expensed immediately to the consolidated statement of income.

Exploration and evaluation costs may include: license acquisition, geological and geophysical studies (i.e., seismic), direct labor costs and drilling costs of exploratory wells. No depreciation and/or amortization are charged during the exploration and evaluation phase. Upon completion of the evaluation phase, the prospects are either transferred to oil and gas properties or charged to expense in the period in which the determination is made, depending whether they have found reserves. If not developed, exploration and evaluation assets are written off after three years, unless it can be clearly demonstrated that the carrying value of the investment is recoverable. All field development costs are considered construction in progress until they are finished and capitalized within oil and gas properties, and are subject to depreciation once completed. Such costs may include the acquisition and installation of production facilities, development drilling costs (including dry holes, service wells and seismic surveys for development purposes), project-related engineering and the acquisition costs of rights and concessions related to proved properties.

Workovers of wells made to develop reserves and/or increase production are capitalized as development costs. Maintenance costs are charged to income when incurred.

Capitalized costs of proved oil and gas properties and production facilities and machinery are depreciated on a licensed area by licensed area basis, using the unit of production method, based on commercial proved and probable reserves. The calculation of the "unit of production" depreciation takes into account estimated future finding and development costs, and is based on current year-end un-escalated price levels. Changes in reserves and cost estimates are recognized prospectively. Reserves are converted to equivalent units on the basis of approximate relative energy content.

Oil and gas reserves for purposes of our Consolidated Financial Statements are determined in accordance with PRMS, and were estimated by DeGolyer and MacNaughton, independent reserves engineers.

Depreciation of the remaining property, plant and equipment assets (i.e., furniture and vehicles) not directly associated with oil and gas activities has been calculated by means of the straight line method by applying such annual rates as required to write-off their value at the end of their estimated useful lives. The useful lives range between three and 10 years.

## Asset retirement obligations

Obligations related to the plugging and abandonment of wells once operations are terminated may result in the recognition of significant liabilities. We record the fair value of the liability for asset retirement obligations in the period in which the wells are drilled. When the liability is initially recognized, the cost is also capitalized by increasing the carrying amount of the related asset. Over time, the liability is accreted to its present value at each reporting date, and the capitalized cost is depreciated over the estimated useful life of the related asset. Estimating the future abandonment costs is difficult and requires management to make assumptions and judgments because most of the obligations will be settled after many years. Technologies and costs are constantly changing, as



are political, environmental, health, safety and public relations considerations. Consequently, the timing and future cost of dismantling and abandonment are subject to significant modification. Any change in the variables underlying our assumptions and estimates can have a significant effect on the liability and the related capitalized asset and future charges related to the retirement obligations. The present value of future costs necessary for well plugging and abandonment is calculated for each area at the present value of the estimated future expenditure. The liability recognized is based upon estimated future abandonment costs, wells subject to abandonment, time to abandonment, and future inflation rates.

## Share-based payments

We provide several equity-settled, share-based compensation plans to certain employees and third-party contractors, composed of payments in the form of share awards and stock options plans.

Fair value of the stock option plans for employee or contractor services received in exchange for the grant of the options is recognized as an expense. The total amount to be expensed over the vesting period, which is the period over which all specified vesting conditions are to be satisfied, is determined by reference to the fair value of the options granted calculated using the Geometric Brownian Motion method. Determining the total value of our share-based payments requires the use of highly subjective assumptions, including the expected life of the stock options, estimated forfeitures and the price volatility of the underlying shares. The assumptions used in calculating the fair value of share-based payment represent management's best estimates, but these estimates involve inherent uncertainties and the application of management's judgment.

Non-market vesting conditions are included in assumptions in respect of the number of options that are expected to vest. At each balance sheet date, we revise our estimates of the number of options that are expected to vest. We recognize the impact of the revision to original estimates, if any, in the consolidated statement of income, with a corresponding adjustment to equity.

The fair value of the share awards payments is determined at the grant date by reference of the market value of the shares and recognized as an expense over the vesting period.

When options are exercised, we issue new common shares. The proceeds received net of any directly attributable transaction costs are credited to share capital (nominal value) and share premium when the options are exercised.

## Taxation

The computation of our income tax expense involves the interpretation of applicable tax laws and regulations in many jurisdictions. The resolution of tax positions taken by us, through negotiations with relevant tax authorities or through litigation, can take several years to complete and in some cases it is difficult to predict the ultimate outcome.
In addition, we have tax-loss carry-forwards in certain taxing jurisdictions that are available to offset against future taxable profit. However, deferred tax assets are recognized only to the extent that it is probable that taxable profit will be available against which the unused tax losses can be utilized. Management judgment is exercised in assessing whether this is the case.

To the extent that actual outcomes differ from management’s estimates, taxation charges or credits may arise in future periods.

## Contingencies

From time to time, we may be subject to various lawsuits, claims and proceedings that arise in the normal course of business, including employment, commercial, environmental and health & safety matters. For example, from time to time, the Company receives notices of environmental, health and safety violations. Based on what our Management currently knows, such claims are not expected to have a material impact on the financial statements.

## Recent accounting pronouncements

See Note 2.1.1 to our Consolidated Financial Statements.

We have set up a project team by business unit which has reviewed each business unit’s leasing arrangements over the last year in light of the new lease accounting rules in IFRS 16.

As of December 31, 2018, we have non-cancellable operating lease commitments of US$ 69.9 million. Of these commitments, we expect to recognize right-of-use assets and lease liabilities, at nominal value, of approximately US$ 14.5 million on January 1, 2019. The remaining lease commitments, in accordance with IFRS 16, will be recognized on a straight-line basis as expense in the consolidated statement of income.

There will not be an impact on Adjusted EBITDA as a consequence of the adoption of this new standard.

Operating cash flows will increase and financing cash flows will decrease by approximately US$ 4 million, as repayment of the principal portion of the lease liabilities will be classified as cash flows from financing activities.

We have applied the standard from the mandatory adoption date of January 1, 2019. We intend to apply the simplified transition approach and as a result, will not restate comparative amounts for the year prior to first adoption.

## Results of operations

The following discussion is of certain financial and operating data for the periods indicated. You should read this discussion in conjunction with our Consolidated Financial Statements and the accompanying notes.

In preparation for continued volatility, we have developed multiple scenarios for our 2019 capital expenditure program. See “Item 4. Information on the Company –B. Business Overview—2019 Strategy and Outlook.”

Revenue attributable to our operations in Brazil for the year ended December 31, 2018 was US$30.0 million, a 12% decrease from US$34.2 million for the year ended December 31, 2017, principally due to lower gas prices and deliveries. The contribution to our revenue from our operations in Brazil during the years ended December 31, 2018 and 2017 was 5% in each year.

Revenue attributable to our operations in Argentina, primarily from the acquired blocks in Argentina, for the year ended December 31, 2018 was US$ 35.9 million, representing 6% of our total consolidated sales. The average realized price per barrel of crude oil increased from US$52.3 per barrel to US$65.0 per barrel.

Consolidated production and operating costs increased 76%, from US99.0 million for the year ended December 31, 2017 to US174.3 million for the year ended December 31, 2018, primarily due to the new operation of the blocks in Argentina, higher royalties paid in cash, in line with increased production and a higher royalty rate in Colombia, and increased operating costs related to higher sales volumes.

Production and operating costs in Colombia increased 77%, to US$118.5 million for the year ended December 31, 2018, as compared to US$66.9 million for the year ended December 31, 2017, primarily due to higher royalties of US$38.5 million, in line with increased production, a higher royalty rate and higher oil prices. In addition, operating costs per boe in Colombia remained at US$5.6 per boe for the year ended December 31, 2018.

Production and operating costs in Chile increased by 4% to US21.9 million due to higher staff costs expenses and pulling campaign. Costs per boe increased to US$22.8 per boe from US$20.3 per boe in 2017. In the year ended December 31, 2018, the revenue mix for Chile was 46.6% oil and 53.4% gas, whereas for the same period in 2017 it was 48.5% oil and 51.5% gas.

Production and operating costs in Brazil decreased by 18%, to US$8.8 million for the year ended December 31, 2018, as compared to the year ended December 31, 2017, mainly resulting from non-recurring maintenance costs in Manati Field. Operating costs per boe decreased to US$6.1 for the year ended December 31, 2018 from US$7.8 per boe for the year ended December 31, 2017.

Production and operating costs in Argentina amounted to US$25.0 million for the year ended December 31, 2018, mainly resulting from the operation of the blocks we acquired in Neuquén. Operating costs per boe amounted to US$31.2 for the year ended December 31, 2018.

## Geological and geophysical expenses

<table><tr><td></td><td colspan="2">Year ended December 31</td><td colspan="2">Change from prior year</td></tr><tr><td></td><td colspan="4">(in thousands of US, except for percentages)</td></tr><tr><td></td><td>2018</td><td>2017</td><td>%</td><td></td></tr><tr><td>Colombia</td><td>(6,288)</td><td>(2,231)</td><td>(4,057)</td><td>182%</td></tr><tr><td>Chile</td><td>(733)</td><td>(858)</td><td>125</td><td>(15)%</td></tr><tr><td>Brazil</td><td>(827)</td><td>(1,007)</td><td>180</td><td>(18)%</td></tr><tr><td>Argentina</td><td>(1,694)</td><td>(22)</td><td>(1,672)</td><td>7,600%</td></tr><tr><td>Other</td><td>(4,409)</td><td>(3,576)</td><td>(833)</td><td>23%</td></tr><tr><td>Total</td><td>(13,951)</td><td>(7,694)</td><td>(6,257)</td><td>81%</td></tr></table>

Geological and geophysical expenses increased 81%, from US$7.7 million for the year ended December 31, 2017 to US$14.0 million for the year ended December 31, 2018, primarily as the result of lower allocation to capitalized projects in Colombia due to: (i) decreased exploratory drilling activity levels totalling US$4.1 million, (ii) the new operation of the blocks in Argentina which increased US$1.7 million and (iii) a higher level of activities in Peru for an amount of US$0.5 million.

## Administrative costs

<table><tr><td></td><td colspan="2">Year ended December 31</td><td colspan="2">Change from prior year</td></tr><tr><td></td><td colspan="4">(in thousands of US\), except for percentages)</td></tr><tr><td></td><td>2018</td><td>2017</td><td></td><td>%</td></tr><tr><td>Colombia</td><td>(24,910)</td><td>(17,567)</td><td>(7,343)</td><td>42%</td></tr><tr><td>Chile</td><td>(5,671)</td><td>(6,331)</td><td>660</td><td>(10)%</td></tr><tr><td>Brazil</td><td>(2,628)</td><td>(2,444)</td><td>(184)</td><td>8%</td></tr><tr><td>Argentina</td><td>(2,847)</td><td>(2,057)</td><td>(790)</td><td>38%</td></tr><tr><td>Other</td><td>(16,018)</td><td>(13,655)</td><td>(2,363)</td><td>17%</td></tr><tr><td>Total</td><td>(52,074)</td><td>(42,054)</td><td>(10,020)</td><td>24%</td></tr></table>

Administrative costs increased 24%, from US$42.1 million for the year ended December 31, 2017 to US$52.1 million for the year ended December 31, 2018, mainly due to higher consultant fees and travel expenses for an amount of US$3.3 million, higher staff costs for an amount of US$2.7 million and higher other expenses related to our growth strategy and new business.

## Selling expenses

<table><tr><td></td><td colspan="2">Year ended December 31,</td><td colspan="2">Change from prior year</td></tr><tr><td></td><td colspan="4">(in thousands of US\), except for percentages)</td></tr><tr><td></td><td>2018</td><td>2017</td><td></td><td>%</td></tr><tr><td>Colombia</td><td>(1,028)</td><td>(250)</td><td>(778)</td><td>311%</td></tr><tr><td>Chile</td><td>(533)</td><td>(688)</td><td>155</td><td>(23)%</td></tr><tr><td>Argentina</td><td>(2,462)</td><td>(198)</td><td>(2,264)</td><td>1143%</td></tr><tr><td>Total</td><td>(4,023)</td><td>(1,136)</td><td>(2,887)</td><td>254%</td></tr></table>

Selling expenses increased 254%, from US$1.1 million for year ended December 31, 2017 to US$4.0 million for the year ended December 31, 2018, primarily due to transportation costs and selling taxes in the Aguada Baguales, El Porvenir and Puesto Touquet blocks in Argentina.

## Commodity risk management contracts

We recorded a profit of US$16.2 million related to commodity risk management contracts for the year ended December 31, 2018 and a loss of US$15.4 million for the year ended December 31, 2017. Realized losses reflect cash settled transactions and unrealized losses reflect non-cash changes between the contract values and the forward Brent oil curve.

## Depreciation

<table><tr><td></td><td colspan="2">Year ended December 31,</td><td colspan="2">Change from prior year</td></tr><tr><td></td><td colspan="4">(in thousands of US\), except for percentages)</td></tr><tr><td></td><td>2018</td><td>2017</td><td></td><td>%</td></tr><tr><td>Colombia</td><td>(42,721)</td><td>(40,010)</td><td>(2,711)</td><td>7%</td></tr><tr><td>Chile</td><td>(28,203)</td><td>(23,730)</td><td>(4,473)</td><td>19%</td></tr><tr><td>Brazil</td><td>(10,395)</td><td>(10,809)</td><td>414</td><td>(4)%</td></tr><tr><td>Argentina</td><td>(10,640)</td><td>(159)</td><td>(10,481)</td><td>66%</td></tr><tr><td>Other</td><td>(281)</td><td>(177)</td><td>(104)</td><td>59%</td></tr><tr><td>Total</td><td>(92,240)</td><td>(74,885)</td><td>(17,355)</td><td>23%</td></tr></table>



Depreciation charges increased by 23% from US$74.9 million for the year ended December 31, 2017 to US$92.2 million for the year ended December 31, 2018, mainly due to the new operation of the blocks in Argentina and increased volumes. However, depreciation costs per boe decreased from US$7.9 to US$7.1 per boe due to drilling successes and increased reserves in Colombia.

## Operating profit (loss)

<table><tr><td rowspan="2"></td><td colspan="3">Year ended December 31,</td><td colspan="3">Change from prior year</td></tr><tr><td colspan="3">(in thousands of US, except for percentages)</td><td colspan="3">(in thousands of US, except for percentages)</td></tr><tr><td></td><td>2018</td><td>2017</td><td></td><td></td><td></td><td></td></tr><tr><td>Colombia</td><td>309,357</td><td>116,290</td><td>193,067</td><td>166%</td><td></td><td></td></tr><tr><td>Chile</td><td>(29,139)</td><td>(19,675)</td><td>(9,464)</td><td>48%</td><td></td><td></td></tr><tr><td>Brazil</td><td>4,370</td><td>4,434</td><td>(64)</td><td>(1)%</td><td></td><td></td></tr><tr><td>Argentina</td><td>(6,739)</td><td>(3,430)</td><td>(3,309)</td><td>96%</td><td></td><td></td></tr><tr><td>Other</td><td>(21,357)</td><td>(18,623)</td><td>(2,734)</td><td>15%</td><td></td><td></td></tr><tr><td>Total</td><td>256,492</td><td>78,996</td><td>177,496</td><td>225%</td><td></td><td></td></tr></table>

We recorded an operating profit of US$256.5 million for the year ended December 31, 2018, a 225% improvement from the operating profit of US$79.0 million for the year ended December 31, 2017, primarily due to an increase in revenue and other gains, as described above.

In 2018, we recorded a write-off of unsuccessful exploration efforts of US$26.4 million that corresponded to nine unsuccessful exploratory wells, four wells drilled in Colombia (Triple, Llanos 34 and Llanos 32 Blocks), two wells drilled in Brazil (POT-T-747 and POT-T-619 Blocks) and three wells drilled in Argentina (Puelen Block). The charge also included the write-off of a well and other exploration costs incurred in the Fell Block in previous years and other exploration costs incurred in the VIM-3 Block, and POT-T-882 and REC-T-93 Blocks, for which no additional work would be performed. This was partially offset by a gain on non-cash impairments reversal of non-financial assets amounting to US$5.0 million. This amount comprised: (i) US$11.5 million gain in Colombia, resulting from an improved oil price environment and the known fair value less costs of disposal of the La Cuerva and Yamu Blocks; and (ii) US$6.5 million impairment loss due to the termination of the sales agreement for the TdF's blocks, with no renovation in place as of the date of this annual report.

## Financial costs

Financial costs decreased 30% to US$36.3 million for the year ended December 31, 2018 as compared to US$51.5 million for the year ended December 31, 2017, mainly due to one-time costs on the cancellation of 2020 Notes for an amount of US$17.6 million recognized in 2017.

## Foreign exchange (loss) gain

Foreign exchange variation increased from a loss of US$2.2 million for the year ended December 31, 2017 compared to a loss of US$11.3 million for the year ended December 31, 2018, mainly due to the depreciation of the Brazilian real in the 2017 and 2018 period. Foreign exchange differences are mainly generated from changes in the value of the Brazilian real over the U.S. Dollar-denominated debt incurred at the local subsidiary level, where the functional currency is the Brazilian real.

## Profit before income tax

For the year ended December 31, 2018, we recorded a profit before income tax of US$208.9 million, compared to a profit of US$25.3 million for the year ended December 31, 2017, primarily due to profits recorded in our Colombian operations.

<table><tr><td>Income tax expense</td><td colspan="2">Year ended December 31</td><td colspan="2">Change from prior year</td></tr><tr><td></td><td colspan="2">(in thousands of US\), except for percentages)</td><td></td><td></td></tr><tr><td></td><td>2018</td><td>2017</td><td></td><td>%</td></tr><tr><td>Colombia</td><td>(119,730)</td><td>(45,406)</td><td>(74,324)</td><td>164%</td></tr><tr><td>Chile</td><td>6,090</td><td>856</td><td>5,234</td><td>611%</td></tr><tr><td>Brazil</td><td>1,762</td><td>36</td><td>1,726</td><td>4,794%</td></tr><tr><td>Argentina</td><td>5,752</td><td>-</td><td>5,752</td><td>100%</td></tr><tr><td>Other</td><td>(114)</td><td>1,369</td><td>(1,483)</td><td>(108)%</td></tr><tr><td>Total</td><td>(106,240)</td><td>(43,145)</td><td>(63,095)</td><td>146%</td></tr></table>

Our effective tax rate was 51% for the year ended December 31, 2018, compared to 170% in 2017. The decrease in the effective tax rate was primarily due to an increase in profits recorded in our Colombian operations as compared to the other countries and the incorporation of the Argentine operations.

## Revenue

For the year ended December 31, 2017, crude oil sales were our principal source of revenue, with 85% and 15% of our total revenue from crude oil and gas sales, respectively. The following chart shows the change in oil and natural gas sales from the year ended December 31, 2016 to the year ended December 31, 2017.

Revenue increased 71%, from US$192.7 million for the year ended December 31, 2016 to US$330.1 million for the year ended December 31, 2017, primarily as a result of higher oil revenues. Sales of crude oil increased due to higher realized prices and higher sold volumes of 7.9 mmbbl in the year ended December 31, 2017 compared to 5.9 mmbbl in the year ended December 31, 2016, and resulted in net revenue of US$279.2 million for the year ended December 31, 2017 compared to US$145.2 million for the year ended December 31, 2016. In addition, sales of gas increased from US$47.5 million for the year ended December 31, 2016 to US$51.0 million for the year ended December 31, 2017 due to increased sales volumes and higher realized prices.

The increase in 2017 net revenue of US$137.5 million is mainly explained by:
• an increase of US$136.8 million in sales in Colombia, due to an increase in price and volume;

• a decrease of US$4 million in sales in Chile, including decreases of US$2.9 million in oil sales and US$1.1 million of gas sales; and

• an increase of US$4.3 million in gas sales in Brazil, related to our Manati operations;

all of which was due principally to higher oil and gas prices, as further described below.

Revenue attributable to our operations in Colombia for the year ended December 31, 2017 was US$263.1 million, compared to US$126.2 million for the year ended December 31, 2016, representing 80% and 66% of our total consolidated sales. The increase is related to an increase in oil deliveries from 5.4 mmbbl to 7.6 mmbbl and an increase in the average realized price per barrel of crude oil from US$24.4 per barrel to US$36.1 per barrel, primarily due to higher reference international prices.

Revenue attributable to our operations in Chile for the year ended December 31, 2017 was US$32.7 million, a 11% decrease from US$36.7 million for the year ended December 31, 2016, principally due to (1) decreased sales of crude oil of 0.3 mmbbl for the year ended December 31, 2017 compared to 0.5 mmbbl for the year ended December 31, 2016 (a decrease of 40%) due to the decline in oil base production, (2) a decrease in gas sales by US$1.1 million, due to decreased gas production levels as compared to the previous year. This was partially offset by increased average realized prices per barrel of crude oil from US$37.0 per barrel for the year December 31, 2016 to US$45.7 per barrel for the year ended December 31, 2017 (an increase of US$8.7 per barrel or a total of 24%). The increase in the average realized price per barrel was attributable to higher international reference prices. The contribution to our revenue during such years from our operations in Chile was 10% and 19%, respectively.



Revenue attributable to our operations in Brazil for the year ended December 31, 2017 was US$34.2 million, a 15% increase from US$29.7 million for the year ended December 31, 2016, principally due to higher gas prices. The contribution to our revenue from our operations in Brazil during the years ended December 31, 2017 and 2016 was 10% and 15%, respectively.

## Production and operating costs

The following table summarizes our production and operating costs for the years ended December 31, 2017 and 2016.

Consolidated production and operating costs increased 47%, from US67.2 million for the year ended December 31, 2016 to US99.0 million for the year ended December 31, 2017, primarily due to higher royalties paid in cash, in line with increased production (the Jacana oil field accumulated more than 5 mmbbl during the year ended December 31, 2017, triggering a higher royalty rate in Colombia), and higher oil prices, and increased operating costs related to higher sales volumes.

Production and operating costs in Colombia increased 83%, to US66.9 million for the year ended December 31, 2017, as compared to US36.6 million for the year ended December 31, 2016, primarily due to (i) higher royalties of US17.0 million, in line with increased production (the Jacana oil field accumulated more than 5 mmbbl during the year ended December 31, 2017, triggering a higher royalty rate in Colombia) and higher oil prices, and (ii) increased costs associated with higher production and the reopening of the Cuerva and Yamu Blocks, which are mature fields with higher operating costs than the Llanos 34 Block. In addition, operating costs per boe in Colombia increased to US55.6 per boe for the year ended December 31, 2017 from US5.4 per boe for the year ended December 31, 2016.

Production and operating costs in Chile decreased by 5% to US21.0 million due to lower oil and gas production levels. Costs per boe increased to US20.3 per boe from US15.8 per boe in 2016. In the year ended December 31, 2017, the revenue mix for Chile was 48.5% oil and 51.5% gas, whereas for the same period in 2016 it was 51.1% oil and 48.9% gas.

Production and operating costs in Brazil increased by 27%, to US10.7 million for the year ended December 31, 2017, as compared to the year ended December 31, 2016, mainly resulting from non-recurring maintenance costs in Manati Field. Operating costs per boe increased to US7.8 for the year ended December 31, 2017 from US5.8 per boe for the year ended December 31, 2016.

## Geological and geophysical expenses

Geological and geophysical expenses decreased 25%, from US10.3 million for the year ended December 31, 2016 to US7.7 million for the year ended December 31, 2017, primarily as the result of higher allocation to capitalized projects due to increased drilling activity levels.

## Administrative costs

<table><tr><td rowspan="2"></td><td colspan="4">Year ended December 31,</td></tr><tr><td colspan="4">(in thousands of US\), except for percentages)</td></tr><tr><td></td><td></td><td></td><td></td><td>% Change</td></tr><tr><td></td><td>2017</td><td>2016</td><td></td><td>from prior</td></tr><tr><td>Colombia</td><td>(17,567)</td><td>(14,715)</td><td>(2,852)</td><td>19%</td></tr><tr><td>Chile</td><td>(6,331)</td><td>(7,153)</td><td>822</td><td>(11)%</td></tr><tr><td>Brazil</td><td>(2,444)</td><td>(3,085)</td><td>641</td><td>(21)%</td></tr><tr><td>Other</td><td>(15,712)</td><td>(9,217)</td><td>(6,495)</td><td>70%</td></tr><tr><td>Total</td><td>(42,054)</td><td>(34,170)</td><td>(7,884)</td><td>23%</td></tr></table>

Administrative costs increased 23%, from US34.2 million for the year ended December 31, 2016 to US42.1 million for the year ended December 31, 2017, mainly due to higher staff costs and consulting fees resulting from an increased scale of operations.

## Selling expenses

<table><tr><td rowspan="2"></td><td colspan="4">Year ended December 31,</td></tr><tr><td colspan="4">(in thousands of US\), except for percentages)</td></tr><tr><td></td><td></td><td></td><td></td><td>% Change</td></tr><tr><td></td><td>2017</td><td>2016</td><td></td><td>from prior</td></tr><tr><td>Colombia</td><td>(250)</td><td>(2,830)</td><td>2,580</td><td>(91)%</td></tr><tr><td>Chile</td><td>(688)</td><td>(994)</td><td>306</td><td>(31)%</td></tr><tr><td>Brazil</td><td>-</td><td>(20)</td><td>20</td><td>(100)%</td></tr><tr><td>Other</td><td>(198)</td><td>(378)</td><td>180</td><td>(48)%</td></tr><tr><td>Total</td><td>(1,136)</td><td>(4,222)</td><td>3,086</td><td>(73)%</td></tr></table>

Selling expenses decreased 73%, from US4.2 million for year ended December 31, 2016 to US1.1 million for the year ended December 31, 2017, primarily due to the Trafigura offtake agreement as sales occur at the wellhead in our Colombian operations, which are recorded as a discount to the oil price.

## Commodity risk management contracts

We recorded a loss of US15.4 million related to commodity risk management contracts for the year ended December 31, 2017. Realized losses reflect cash settled transactions and unrealized losses reflect non-cash changes between the contract values and the forward Brent oil curve.

## Depreciation

Depreciation charges decreased by 1% from US75.8 million for the year ended December 31, 2016 to US74.9 million for the year ended December 31, 2017, mainly due to lower production levels in Chile and Brazil, and lower depreciation



costs per barrel in Colombia. Depreciation costs per boe decreased from US$9.9 to US$7.9 per boe.

<table><tr><td rowspan="2"></td><td colspan="5">Year ended December 31,</td></tr><tr><td colspan="5">(in thousands of US\), except for percentages)</td></tr><tr><td></td><td></td><td></td><td></td><td>% Change from prior year</td><td></td></tr><tr><td></td><td>2017</td><td>2016</td><td></td><td></td><td></td></tr><tr><td>Colombia</td><td>116,290</td><td>31,464</td><td>84,826</td><td>270%</td><td></td></tr><tr><td>Chile</td><td>(19,675)</td><td>(44,969)</td><td>25,294</td><td>(56)%</td><td></td></tr><tr><td>Brazil</td><td>4,434</td><td>(644)</td><td>5,078</td><td>(789)%</td><td></td></tr><tr><td>Other</td><td>(22,053)</td><td>(14,464)</td><td>(7,589)</td><td>52%</td><td></td></tr><tr><td>Total</td><td>78,996</td><td>(28,613)</td><td>107,609</td><td>(376)%</td><td></td></tr></table>

We recorded an operating profit of US$79.0 million for the year ended December 31, 2017, a 376% improvement from the operating loss of US$28.6 million for the year ended December 31, 2016, primarily due to an increase in revenue and other gains and a decrease in certain expenses and depreciation, as described above. In 2016, we recorded a gain on non-cash impairments reversal of non-financial assets amounting to US$5.7 million in Colombia, resulting from an improved oil price environment and improvements in cost structure.

## Financial costs

Financial costs increased 51% to US$51.5 million for the year ended December 31, 2017 as compared to US$34.1 million for the year ended December 31, 2016, mainly due to one-time costs on the cancellation of 2020 Notes for an amount of US$17.6 million.

## Foreign exchange (loss) gain

Foreign exchange variation decreased from a gain of US$13.9 million for the year ended December 31, 2016 compared to a loss of US$2.2 million for the year ended December 31, 2017, mainly due to the appreciation of the Brazilian real in the 2016 period and its depreciation in the 2017 period. Foreign exchange differences are mainly generated from changes in the value of the Brazilian real over the U.S. Dollar-denominated debt incurred at the local subsidiary level, where the functional currency is the Brazilian real.

## B. Liquidity and capital resources

## Overview

Our financial condition and liquidity is and will continue to be influenced by a variety of factors, including:

• changes in oil and natural gas prices and our ability to generate cash flows from our operations;

• our capital expenditure requirements;

• the level of our outstanding indebtedness and the interest we are obligated to pay on this indebtedness; and

• changes in exchange rates which will impact our generation of cash flows from operations when measured in US$, and the real.

Our principal sources of liquidity have historically been contributed shareholder equity, debt financings and cash generated by our operations. We have also in the past entered into offtake and prepayment agreements.

Since 2005 to 2018, we have raised approximately US$200 million in equity offerings at the holding company level and nearly US$1 billion through debt arrangements with multilateral agencies such as the IFC, gas prepayment facilities with Methanex, international bond issuances and bank financings, described further below, which have been used to fund our capital expenditures program and acquisitions and to increase our liquidity.

In February 2014, we commenced trading on the NYSE and raised US$98 million (before underwriting commissions and expenses), including the overallotment option granted to and exercised by the underwriters, through the issuance of 13,999,700 common shares.

In September 2017, we issued US$425.0 million aggregate principal amount of senior notes due 2024. The Notes due 2024 mature on September 21, 2024 and bear interest at a fixed rate of 6.50% and a yield of 6.50% per year. Interest on the Notes due 2024 is payable semi-annually in arrears on March 21 and September 21 of each year. The Indenture governing our Notes due 2024 contains incurrence-based limitations on the amount of indebtedness we can incur. This limits our capacity to incur additional indebtedness, other than permitted debt, as specified in the indenture governing the Notes due 2024. The net proceeds from the Notes due 2024 were used by us (i) to make a capital contribution to our wholly-owned subsidiary, GeoPark Latin America Limited Agencia en Chile, providing it with sufficient funds to fully repay the Notes due 2020 and to pay any related fees and expenses, including a call premium, and (ii) for general corporate purposes, including capital expenditures, such as the acquisition of Aguada Baguales, El Porvenir and Puesto Touquet blocks in Neuquén Basin in Argentina, and to repay existing indebtedness, including the Itaú loan.

We believe that our current operations and 2019 capital expenditures program can be funded from cash flow from existing operations and cash on hand. Should our operating cash flow decline due to unforeseen events, including delivery restrictions or a protracted downturn in oil and gas prices, we would examine measures such as further capital expenditure program reductions, pre-sale agreements, disposition of assets, or issuance of equity, among others.

## Capital expenditures

In the past, we have funded our capital expenditures with proceeds from equity offerings, credit facilities, debt issuances and pre-sale agreements, as well as through cash generated from our operations. We expect to incur substantial expenses and capital expenditures as we develop our oil and natural gas prospects and acquire additional assets. See “Item 4. Information on the Company –B. Business Overview—2019 Strategy and Outlook.”

In the year ended December 31, 2018, we made total capital expenditures of US$124.7 million (US$97.0 million, US$8.0 million, US$9.0 million, US$8.5 million and US$2.3 million in Colombia, Chile, Argentina, Peru and Brazil, respectively).

In the year ended December 31, 2017, we made total capital expenditures of US$105.6 million (US$80.0 million, US$10.2 million, US$8.2 million, US$3.6 million and US$3.6 million in Colombia, Chile, Argentina, Peru and Brazil, respectively).

## Cash flows provided by operating activities

For the year ended December 31, 2018, cash provided by operating activities was US$256.2 million, an 80% increase from US$142.2 million for the year ended December 31, 2017, resulting from the increase in oil prices and deliveries in 2018 as compared to 2017, net of increased income taxes paid predominantly from Colombia for an amount of US$60.8 million.

For the year ended December 31, 2017, cash provided by operating activities was US$142.2 million, a 72% increase from US$82.9 million for the year ended December 31, 2016, resulting from the increase in oil prices in 2017 as compared to 2016, net of a US$15.6 million advance payment paid in December 2017 to Pluspetrol, as a security deposit related to the recently announced acquisition of Aguada Baguales, El Porvenir and Puesto Touquet blocks in Neuquén Basin in Argentina.



## Cash flows used in investing activities

For the year ended December 31, 2018, cash used in investing activities was US$164.6 million, a 56% increase from US$105.6 million for the year ended December 31, 2017. This increase was related to the acquisition of the blocks in Argentina for an amount of US$48.9 million and capital expenditures related to development, appraisal and exploration activities.

For the year ended December 31, 2017, cash used in investing activities was US$105.6 million, a 169% increase from US$39.3 million for the year ended December 31, 2016. This increase was related to higher capital expenditures in Colombia, Chile, Argentina and Peru in 2017 as compared to 2016.

## Cash flows from financing activities

Cash from financing activities was US$24.0 million for the year ended December 31, 2017, compared to US$51.1 million used in financing activities for the year ended December 31, 2016. This change was principally related to net proceeds from the issuance of 2024 Notes of US$418.3 million offset by principal paid of US$355.0 million related to the payment of 2020 Notes and the prepayment of the Itaú loan.

Cash from financing activities was US$97.6 million for the year ended December 31, 2018, compared to US$24.0 million used in financing activities for the year ended December 31, 2017. This increase was principally related to acquisition of the LGI non-controlling interest in Colombia and Chile's equity interest for which we paid US$81.0 million. In addition, we paid US$8.0 million for dividends to LGI prior to the acquisition and used US$1.8 million to purchase our own equity securities during 2018.

## Indebtedness

As of December 31, 2018 and 2017, we had total outstanding indebtedness of US$447.0 million and US$426.2 million, respectively, as set forth in the table below.

Our material outstanding indebtedness as of December 31, 2018 is described below.

## Notes due 2024

## General

On September 21, 2017, we issued US425.0 million aggregate principal amount of senior notes due 2024. The Notes due 2024 mature on September 21, 2024 and bear interest at a fixed rate of 6.50% and a yield of 6.50% per year. Interest on the Notes due 2024 is payable semi-annually in arrears on March 21 and September 21 of each year.

## Ranking

The Notes due 2024 constitute senior unsubordinated obligations of GeoPark Limited, and are guaranteed by Geopark Chile S.A., Geopark Colombia Coöperatie U.A. (the "Guarantors"). The Notes due 2024 rank equally in right of payment with all existing and future senior obligations of GeoPark Limited and the Guarantors (except those obligations preferred by operation of law, including without limitation labor and tax claims); rank senior in right of payment to all existing and future subordinated indebtedness of GeoPark Limited and the Guarantors; and rank effectively junior to any secured obligations of GeoPark Limited, the Guarantors and their respective subsidiaries to the extent of the value of the collateral securing such obligations.

## Optional redemption

We may, at our option, redeem all or part of the Notes due 2024, at the redemption prices, expressed as percentages of principal amount, set forth below, plus accrued and unpaid interest thereon (including additional amounts), if any, to the applicable redemption date, if redeemed during the 12-month period beginning on September 21 of the years indicated below:

<table><tr><td>Year</td><td>Percentage</td></tr><tr><td>2021</td><td>103.250%</td></tr><tr><td>2022</td><td>101.625%</td></tr><tr><td>2023 and after</td><td>100.000%</td></tr></table>

## Change of control

Upon the occurrence of certain events constituting a change of control, we are required to make an offer to repurchase all outstanding Notes due 2024, at a purchase price equal to 101% of the principal amount thereof plus any accrued and unpaid interest (including any additional amounts payable in respect thereof) thereon to the date of purchase. If holders of not less than 90% in aggregate principal amount of the outstanding Notes due 2024 validly tender and do not withdraw such notes and we repurchase all such notes, we may redeem the Notes due 2024 that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to but excluding the date of such redemption.

## Covenants

The Notes due 2024 contain customary covenants, which include, among others, limitations on the incurrence of debt and disqualified or preferred stock, restricted payments (including restrictions on our ability to pay dividends),



incurrence of liens, guarantees of additional indebtedness, the ability of certain subsidiaries to pay dividends, asset sales, transactions with affiliates, engaging in certain businesses and merger or consolidation with or into another company.

In the event the Notes due 2024 receive investment-grade ratings from at least two of the following rating agencies, Standard & Poor's, Moody's and Fitch, and no default has occurred or is continuing under the indenture governing the Notes due 2024, certain of these restrictions, including, among others, the limitations on incurrence of debt and disqualified or preferred stock, restricted payments (including restrictions on our ability to pay dividends), the ability of certain subsidiaries to pay dividends, asset sales and certain transactions with affiliates will no longer be applicable.

The indenture governing our Notes due 2024 includes incurrence test covenants that provide, among other things, that, the net debt to EBITDA ratio should not exceed (i) 3.50 until September 21, 2019, (ii) 3.25 from September 21, 2019 to September 21, 2021, and (iii) 3.00 thereafter until maturity, and the EBITDA to interest ratio should exceed (i) 2.00 until September 21, 2019, (ii) 2.25 from September 21, 2019 to September 21, 2021 and (iii) 2.50 thereafter until maturity. Failure to comply with the incurrence test covenants does not trigger an event of default. However, this situation may limit our capacity to incur additional indebtedness, as specified in the indenture governing the Notes due 2024, other than certain categories of permitted debt. We must test incurrence covenants before incurring additional debt or performing certain corporate actions including but not limited to making dividend payments, restricted payments and others (in each case with certain specific exceptions).

## Events of default

Events of default under the indenture governing the Notes due 2024 include: the nonpayment of principal when due; default in the payment of interest, which continues for a period of 30 days; failure to make an offer to purchase and thereafter accept tendered notes following the occurrence of a change of control or as required by certain covenants in the indenture governing the Notes due 2024; cross payment default relating to debt with a principal amount of US$30.0 million or more, and cross-acceleration default following a judgment for US$30.0 million or more; bankruptcy and insolvency events; and invalidity or denial or disaffirmation of a guarantee of the notes. The occurrence of an event of default would permit or require the principal of and accrued interest on the Notes due 2024 to become or to be declared due and payable.

## Banco Santander

During October 2018, we executed a loan agreement with Banco Santander for Brazilian Real 77,640,000 (equivalent to US$ 20,000,000 at the moment of the loan execution) to repay an existing US$-denominated intercompany loan. The interest rate applicable to this loan is the Interbank Certificate of Deposit Rate (“CDI”) plus 2.25% per annum. CDI represents the average rate of all interbank overnight transactions in Brazil. The principal and the interest are paid semi-annually, with final maturity in October 2020.

## Other Agreements

In December 2015, we entered into an offtake and prepayment agreement with Trafigura under which we sell and deliver a portion of our Colombian crude oil production. Pricing will be determined by future spot market prices, net of transportation costs. The agreement also provided us with prepayment of up to US$100 million from Trafigura. Funds committed will be made available to us upon request and will be repaid by us on a monthly basis through future oil deliveries over the period of the contract, which is 2.5 years, including a 6-month grace period. According to the terms of the prepayment agreement, we are required to pay interest of LIBOR plus 5% per year on outstanding amounts. In addition, under the prepayment agreement, we are required to maintain certain coverage ratios linking: (i) future payments to the value of estimated future oil deliveries (net of transportation discounts) during the term of the offtake agreement and (ii) collections to payments within specified periods, with the possibility of delivering additional volumes to meet such ratios in the upcoming 3-month period. As of December 31, 2018, it was fully repaid.

## B. Compensation

## Senior management and director compensation

For the year ended December 31, 2018, we accrued or paid approximately US$4.6 million, in the aggregate, to the members of our board of directors (including our executive directors) for their services in all capacities. During this same period, we accrued or paid approximately US$11.0 million, in the aggregate, to the members of our senior management (excluding our executive directors) for their services in all capacities. An amount of US$0.8 million corresponds to the accrual or payment for discretionary bonus cash payments granted to the Company’s executive directors based on the Company’s performance in 2018. Gerald E. O’Shaughnessy, James F. Park and Pedro E. Aylwin Chiorrini are our executive directors.

## Executive Director Contracts

It is our current policy that executive directors enter into indefinite term contracts with the Company that may be terminated at any time by either party subject to certain notice requirements.

Gerald E. O'Shaughnessy has entered into a service contract with the Company to act as Chairman at an annual salary of US$400,000. James F. Park has entered into a service contract with the Company to act as Chief Executive Officer at an annual salary of US$800,000. They each also received equity awards described below under "Equity Incentive Compensation." Our agreements with Mr. O'Shaughnessy and Mr. Park contain covenants that restrict them, for a period of 12 months following termination of employment, from soliciting senior employees of the Company and, for a period of six months following a termination of employment, from competing with the Company.

Pedro E. Aylwin Chiorrini, who was appointed as an executive director in July 2013, has entered into a service contract with the Company to act as Director of Legal and Governance, and as such has decided to forego his director fees. He received in 2018 a salary of US$0.4 million and bonus of US$0.1 million for his services as a member of senior management.

The following chart summarizes payments made to our executive directors for the year ended December 31, 2018:

<table><tr><td></td><td>Executive Directors&#x27; Fees</td><td>Cash payment</td><td>Payment in shares</td></tr><tr><td></td><td>Executive Directors&#x27; Fees</td><td>Bonus</td><td>Bonus</td></tr><tr><td>Gerald E.

Aylwin Chiorrini</td><td>US$26,000</td><td>—</td><td>—</td></tr></table>

Bonus payments above were approved by the Compensation Committee on May 7, 2018 and reflect discretionary cash bonus payment made based on our performance in 2017. Additionally, Mr. Park’s compensation includes an annual equity award with an aggregate value equal to one year of base salary, based on the previous year’s average share price, and with a three year vesting period. Due to the foregoing, on May 7, 2018, Mr. Park was awarded 104,439 shares based on the 2017 average share price, and; on March 6, 2019, Mr. Park was awarded 52,049 shares, based on the 2018 average share price.

## Non-Executive Director Contracts

The current annual fees paid to our non-executive Directors correspond to US$80,000 to be settled in cash and US$100,000 to be settled in stock, paid quarterly in equal installments. In the event that a non-executive Director serves as Chairman of any Board Committees, an additional annual fee of US$20,000 applies. A Director who serves as a member of any Board Committees receives an annual fee of US$10,000. Total payment due shall be calculated on an aggregate basis for Directors serving in more than one Committee. The Chairman fee is not added to the member's fee while serving for the same Committee.

## Pension and retirement benefits

## Equity Incentive Compensation

Performance-Based Employee Long-Term Incentive Program



Given the expiration of our Stock Awards Plan on November 3, 2018, in December 2018, we adopted the 2018 Equity Incentive Plan (the "Plan") to motivate and reward those participating employees, directors, consultants and advisors of our Group to perform at the highest level and to further the best interests of the Company and our shareholders. The Plan is designed as an omnibus plan, with a 10-year term, and encompasses all forms of equity incentive that the Company may wish to implement throughout such term. The maximum number of shares available for issuance under the Plan is 5,000,000 shares.

## Stock Awards Plan

Under the Stock Awards Plan, the board of directors, or its designee, could award options or stock awards. An option confers the right to acquire a specified number of common shares of the Company at an exercise price equal to the par value of the common shares subject to such an option. A performance share confers a conditional right to acquire a specified number of common shares for zero or nominal consideration, subject to the achievement of performance conditions and other vesting terms.

On December 17, 2014, we registered 3,435,600 shares with the U.S. SEC for shares to be issued under the Stock Awards Plan. On December 12, 2018 we registered an additional 4,313,645 shares to be issued under such plan. The following table sets forth the common share awards granted to our executive directors, management and employees under the Stock Awards Plan commencing in 2008 through March 31, 2019.

<table><tr><td colspan="4">Number of underlying common shares outstanding</td></tr><tr><td>Grant date</td><td>Vesting date</td><td>Expiration date</td><td></td></tr><tr><td>817,600 \( ^{(1)} \)</td><td>12/15/2010</td><td>12/15/2014</td><td>12/15/2020</td></tr><tr><td>478,000 \( ^{(1)} \)</td><td>12/15/2011</td><td>12/15/2015</td><td>12/15/2021</td></tr><tr><td>379,500</td><td>12/15/2012</td><td>12/15/2016</td><td>12/15/2022</td></tr><tr><td>490,000</td><td>12/31/2014</td><td>12/31/2017</td><td>12/31/2022</td></tr><tr><td>1,619,105 \( ^{(3)} \)</td><td>06/30/2016</td><td>06/30/2019</td><td>06/30/2026</td></tr><tr><td>104,439 \( ^{(4)} \)</td><td>05/07/2018</td><td>05/07/2021</td><td>03/15/2022</td></tr><tr><td>200,000 \( ^{(3)} \)</td><td>05/31/2018</td><td>06/30/2019</td><td>06/30/2026</td></tr><tr><td>52,049 \( ^{(4)} \)</td><td>03/06/2019</td><td>03/06/2022</td><td>03/15/2023</td></tr></table>

 \( ^{(1)} \)  Pedro E. Aylwin Chiorrini holds 40,000 shares of the 2008 award, 25,000 shares of the 2010 award and 12,000 shares of the 2011 award.

(2) James F. Park received 450,000 shares of such awards, and Gerald E. O'Shaughnessy received 270,000 shares of such awards.

 \( ^{(3)} \) Vesting of these common share awards was subject to the achievement of certain minimum financial and operational targets during a performance period ran from 2016 to 2018.

 \( ^{(4)} \)  James F. Park received these awards on May 5, 2018 and March 6, 2018, respectively, as part of his long-term equity incentive compensation. For further details, please see item 6.B.
Our executive directors, senior management and employees who have received option awards or common share awards under the Stock Awards Plan authorize the Company to deposit any common shares they have received under this plan in our Employee Benefit Trust ("EBT"). The EBT is held to facilitate holdings and dispositions of those common shares by the participants thereof. Under the terms of the EBT, each participant is entitled to receive any dividends we may pay which correspond to their common shares held by the trust, according to instructions sent by the Company to the trust administrator. The trust provides that Mr. James F. Park is entitled to vote all the common shares held in the trust. Although Mr. Park has voting rights with respect to all the common shares held on the trust, Mr. Park disclaims beneficial ownership over the shares in the trust as described under "E. Share Ownership."

## Value Creation Plan

On December 10, 2015, our Board of Directors approved a renewal of the VCP for a new period of three years, with new awards granted on January 1, 2016. Under the VCP, if as of December 31, 2018, our share price has increased by 12% per year according to the plan conditions, VCP participants (key management) will receive awards with an aggregate value equal to 10% of the excess above the market capitalization threshold (12%) generated by this share price (assuming that our share capital remained at the same level as applicable at the time of establishment of the VCP: 59,535,614 shares). The VCP Performance Goals were satisfied and awards thereunder have therefore vested. As per the terms of the VCP, (i) on January 2, 2019, 50% of the vested awards, representing 1,488,390 shares, was issued to participants (including 439,075 issued to directors involved in the performance of the Company), and (ii) in January 2020, the remaining 50% of the awards will be issued. For further details, see Note 30 to our consolidated financial statements. On January 2, 2019, James F. Park received 193,491 shares; Mr. O'Shaughnessy received 89,303 shares; Mr. Aylwin received 111,629 shares and Mr. Gulisano received 44,652 shares due to the VCP issuance.

## Non-Executive Director Plan

In August 2014, our Board of Directors adopted the Non-Executive Director Plan in order to grant shares to non-executive directors as part of their compensation program for serving as directors. The Non-Executive Director Plan was amended and restated in October 2016, when additional 1,000,000 shares were registered as the maximum number of shares available to be issued under this plan. In accordance with the resolutions adopted by our board of directors on May 20, 2014, our non-executive directors are paid their quarterly fees in the form of equity awards granted under the Non-Executive Director Plan. Under the Non-Executive Director Plan, the compensation committee may award common shares, restricted share units and other share-based awards that may be denominated or payable in common shares or factors that influence the value of common shares.

Potential dilution resulting from Equity Incentive Compensation Plans
In accordance with the equity awards granted by the Company under its stock



awards plan, as of December 31, 2018 there were approximately five million and five hundred thousand outstanding shares that had been awarded but which had not yet vested, representing approximately 9% of the total issued share capital as of that date.

## B. Related party transactions

We have entered into the following transactions with related parties:

## LGI Chile Shareholders' Agreements

In November 2018, we acquired all of LGI's equity interest in GeoPark's Chilean and Colombian subsidiaries.

Pursuant to the sale and purchase agreement entered into on November 28, 2018 (the "LGI Termination Agreement"), we agreed to pay LGI a total consideration of up to US$126 million for its entire equity interest in Geopark Chile, Geopark TdF and Geopark Colombia Coöperatie U.A. The acquisition price includes a fixed payment of US$81 million paid at closing, plus two equal installments of US$15 million each, to be paid in June 2019 and June 2020, respectively, and three contingent payments of US$5 million each, which could accrue over the next three years, subject to certain production thresholds being exceeded in the Llanos 34 Block. As a consequence of the LGI Termination Agreement we have become sole shareholder of the entities referred to above. The LGI Chile Shareholders' Agreement, the LGI Colombia Shareholders' Agreement and the LGI line credit, each described in our annual report on the 20-F for the fiscal year ended December 31, 2017 were also terminated.

## Executive Directors' Service Agreements

We have entered into service contracts with certain of our executive directors. See "Item 6. Directors, Senior Management and Employees—B. Compensation—Executive compensation—Director Contracts."

## ITEM 8. FINANCIAL INFORMATION

## A. Consolidated statements and other financial information

## Financial statements

See “Item 18. Financial Statements,” which contains our audited financial statements prepared in accordance with IFRS.

## Legal proceedings

From time to time, we may be subject to various lawsuits, claims and proceedings that arise in the normal course of business, including employment, commercial, environmental, safety and health matters. For example, from time to time, we receive notice of environmental, health and safety violations. It is not presently possible to determine whether any such matters will have a material adverse effect on our consolidated financial position and results of operations.



In Brazil, GeoPark Brasil is a party to a class action filed by the Federal Prosecutor's Office regarding a concession agreement of exploratory Block PN-T-597, which the ANP initially awarded GeoPark Brasil in the 12th oil and gas bidding round held in November 2013. The Brazilian Federal Court issued an injunction against the ANP and GeoPark Brasil in December 2013 that prohibited GeoPark Brasil's execution of the concession agreement until the ANP conducted studies on whether drilling for unconventional resources would contaminate the dams and aquifers in the region. On July 17, 2015, GeoPark Brasil, at the instruction of the ANP, signed the concession agreement, which included a clause prohibiting GeoPark Brasil from conducting unconventional exploration activity in the area. Despite the clause containing the prohibition, the judge in the case concluded that the concession agreement should not be executed. Thus, GeoPark Brasil requested that the ANP comply with the decision and annul the concession agreement, which the ANP's Board did on October 9, 2015. The annulment reverted the status of all parties to the status quo ante, which maintains GeoPark Brasil's right to the block.

## Dividends and dividend policy

Holders of common shares will be entitled to receive dividends, if any, paid on the common shares.

We have never declared or paid any cash dividends on our common shares. We intend to retain all of our future earnings, if any, generated by our operations for the development and growth of our business. Accordingly, we do not expect to pay cash dividends on our common shares in the foreseeable future. Because we are a holding company with no direct operations, we will only be able to pay dividends from our available cash on hand and any funds we receive from our subsidiaries. The terms of our indebtedness may restrict us from paying dividends. We have recorded accumulated losses amounting to US$206.7 million as of December 31, 2018, which further limits our ability to pay dividends in the foreseeable future.

Under the Bermuda Companies Act, we may not declare or pay a dividend if there are reasonable grounds for believing that we are, or would after the payment be, unable to pay our liabilities as they become due or that the realizable value of our assets would thereafter be less than our liabilities. We do not presently have any reasonable grounds for believing that, if we were to declare or pay a dividend on our common shares outstanding, we would thereafter be unable to pay our liabilities as they became due or that the realizable value of our assets would thereafter be less than our liabilities.

Additionally, any decision to pay dividends in the future, and the amount of any distributions, is at the discretion of our board of directors and our shareholders, and will depend on many factors, such as our results of operations, financial condition, cash requirements, prospects and other factors. See "Item 3. Key Information—D. Risk factors—Risks related to our common shares—We have never declared or paid, and do not intend to pay in the foreseeable future, cash dividends on our common shares, and, consequently, your only opportunity to achieve a return on your investment is if the price of our stock appreciates" and "—We are a holding company dependent upon dividends from our subsidiaries, which may be limited by law and by contract from making distributions to us, which would affect our financial condition, including the ability to pay dividends on the common shares," as well as "Item 10. Additional Information—B. Memorandum of association and bye-laws."

## B. Memorandum of association and bye-laws

The following description of our memorandum of association and bye-laws does not purport to be complete and is subject to, and qualified by reference to, all of the provisions of our memorandum of association and bye-laws.

## General

We are an exempted company with limited liability incorporated under the laws of Bermuda with registration number 33273 from the Registrar of Companies. The rights of our shareholders will be governed by Bermuda law and by our memorandum of association and bye-laws. Bermuda company law differs



in some material respects from the laws generally applicable to Delaware corporations. Below is a summary of some of those material differences.

Because the following statements are summaries, they do not discuss all aspects of Bermuda law that may be relevant to us and to our shareholders.

## Share capital and bye-laws

Our share capital consists of common shares only. Our authorized share capital consists of 5,171,949,000 common shares of par value US$0.001 per share. As of the date of this annual report, there are 60,606,787 common shares outstanding. All of our issued and outstanding common shares are fully paid and non-assessable. We also have an employee incentive program, pursuant to which we have granted share awards to our senior management and certain key employees. See “Item 6. Directors, Senior Management and Employees.”

According to our bye-laws, if our share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the terms of issue of the shares of that class) may, whether or not the Company is being wound-up, be varied with the consent in writing of the holders of at least two-thirds of the issued shares of that class or with the sanction of a resolution passed by a majority of the votes cast at a separate general meeting of the holders of the shares of the class at which meeting the necessary quorum shall be two persons at least, in person or by proxy, holding or representing one-third of the issued shares of the class. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith.

Our bye-laws give our board of directors the power to issue any unissued shares of the company on such terms and conditions as it may determine, subject to the terms of the bye-laws and any resolution of the shareholders to the contrary.

## Common shares

Holders of our common shares are entitled to one vote per share on all matters submitted to a vote of holders of common shares. Subject to preferences that may be applicable to any issued and outstanding preference shares, holders of common shares are entitled to receive such dividends, if any, as may be declared from time to time by our board of directors out of funds legally available for dividend payments. Holders of common shares have no redemption, sinking fund, conversion, exchange or other subscription rights. In the event of our liquidation, the holders of common shares are entitled to share equally and ratably in our assets, if any, remaining after the payment of all of our debts and liabilities, subject to any liquidation preference on any outstanding preference shares.

## Board composition

Our bye-laws provide that our board of directors will determine the maximum size of the board, provided that it shall be not be composed of fewer than three directors. The maximum number of directors currently allowed is nine directors and our board of directors currently consists of seven directors.

## Election and removal of directors

Our bye-laws provide that our directors shall hold office for such term as the shareholders shall determine or, in the absence of such determination, until the next annual general meeting or until their successors are elected or appointed or their office is otherwise vacated. Directors whose term has expired may offer themselves for re-election at each election of the directors.

Under our bye-laws, a director may be removed by a resolution adopted by 65% or more of the votes cast by shareholders who (being entitled to do so) vote in person or by proxy at any general meeting of the shareholders in accordance with the provisions of our bye-laws. Notice convened for the purpose of removing the director, containing a statement of the intention to do so, must be served on such director not less than 14 days before the meeting.

Any vacancy created by the removal of a director at a special general meeting may be filled at that meeting by the election of another director in his or her place or, in the absence of any such election, by the board of directors. Any other vacancy, including a newly created directorship, may be filled by our board of directors.

## Proceedings of board of directors

Our bye-laws provide that our business shall be managed by or under the direction of our board of directors. Our board of directors may act by the affirmative vote of a majority of the directors present at a meeting at which a quorum is present. The quorum necessary for the transaction of business at meetings of the board of directors shall be the presence of a majority of the board of directors from time to time. Our bye-laws also provide that resolutions unanimously signed by all directors are valid as if they had been passed at a meeting of the board duly called and constituted.

## Duties of directors

Under Bermuda common law, members of a board of directors owe a fiduciary duty to the Company to act in good faith in their dealings with or on behalf of the company, and to exercise their powers and fulfill the duties of their office honestly. This duty has the following essential elements: (1) a duty to act in good faith in the best interests of the company; (2) a duty not to make a personal profit from opportunities that arise from the office of director; (3) a duty to avoid conflicts of interest; and (4) a duty to exercise powers for the purpose for which such powers were intended. The Bermuda Companies Act also imposes a duty on directors of a Bermuda company, to act honestly and in good faith, with a view to the best interests of the company, and to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. In addition, the Bermuda Companies Act imposes various duties on directors with respect to certain matters of management and administration of the company.



The Bermuda Companies Act provides that in any proceedings for negligence, default, breach of duty or breach of trust against any director, if it appears to a court that such officer is or may be liable in respect of the negligence, default, breach of duty or breach of trust, but that he has acted honestly and reasonably, and that, having regard to all the circumstances of the case, including those connected with his appointment, he ought fairly to be excused for the negligence, default, breach of duty or breach of trust, that court may relieve him, either wholly or partly, from any liability on such terms as the court may think fit. This provision has been interpreted to apply only to actions brought by or on behalf of the company against the directors.

By comparison, under Delaware law, the business and affairs of a corporation are managed by or under the direction of its board of directors. In exercising their powers, directors are charged with a duty of care and a duty of loyalty.

The duty of care requires that directors act in an informed and deliberate manner and to inform themselves, prior to making a business decision, of all relevant material information reasonably available to them. The duty of care also requires that directors exercise care in overseeing the conduct of corporate employees. The duty of loyalty is the duty to act in good faith, not out of self-interest, and in a manner which the director reasonably believes to be in the best interests of the shareholders. A party challenging the propriety of a decision of a board of directors bears the burden of rebutting the presumptions afforded to directors by the “business judgment rule.” If the presumption is not rebutted, the business judgment rule attaches to protect the directors and their decisions. Where, however, the presumption is rebutted, the directors bear the burden of demonstrating the fairness of the relevant transaction. Notwithstanding the foregoing, Delaware courts subject directors’ conduct to enhanced scrutiny in respect of defensive actions taken in response to a threat to corporate control and approval of a transaction resulting in a sale of control of the corporation.

## Interested directors

Pursuant to our bye-laws, a director shall declare the nature of his interest in any contract or arrangement with the company as required by the Bermuda Companies Act. A director so interested shall not, except in particular circumstances set out in our bye-laws, be entitled to vote or be counted in the quorum at a meeting in relation to any resolution in which he has an interest, which is to his knowledge, a material interest (otherwise than by virtue of his interest in shares or debentures or other securities of or otherwise in or through the company). A director will be liable to us for any secret profit realized from the transaction. In contrast, under Delaware law, such a contract or arrangement is voidable unless it is approved by a majority of disinterested directors or by a vote of shareholders, in each case if the material facts as to the interested director's relationship or interests are disclosed or are known to the disinterested directors or shareholders, or such contract or arrangement is fair to the corporation as of the time it is approved or ratified. Additionally, such interested director could be held liable for a transaction in which such director derived an improper personal benefit.

## Indemnification of directors and officers

Bermuda law provides generally that a Bermuda company may indemnify its directors and officers against any loss arising from or liability which by virtue of any rule of law would otherwise be imposed on them in respect of any negligence, default, breach of duty or breach of trust except in cases where such liability arises from fraud or dishonesty of which such director or officer may be guilty in relation to the company.

Our bye-laws provide that we shall indemnify our officers and directors in respect of their actions and omissions, except in respect of their fraud or dishonesty, or to recover any gain, personal profit or advantage to which such director is not legally entitled, and (by incorporation of the provisions of the Bermuda Companies Act) that we may advance monies to our officers and directors for costs, charges and expenses incurred by our officers and directors in defending any civil or criminal proceeding against them on the condition that the officers and directors repay the monies if any allegation of fraud or dishonesty is proved against them provided, however, that, if the Bermuda Companies Act requires, an advancement of expenses shall be made only upon delivery to the Company of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such indemnitee is not entitled to be indemnified for such expenses under this Bye-law or otherwise. Our bye-laws provide that the company and the shareholders waive all claims or rights of action that they might have, individually or in right of the company, against any of the company’s directors or officers for any act or failure to act in the performance of such director’s or officers’ duties, except with respect to any fraud or dishonesty, or to recover any gain, personal profit or advantage to which such director is not legally entitled.

## Meetings of shareholders

Under Bermuda law, a company is required to convene the annual general meeting of shareholders each calendar year, unless the shareholders in a general meeting, elect to dispense with the holding of annual general meetings. Under Bermuda law and our bye-laws, a special general meeting of shareholders may be called by the board of directors and may be called upon the requisition of shareholders holding not less than 10% of the paid-up capital of the company carrying the right to vote at general meetings of shareholders.

Our bye-laws provide that, at any general meeting of the shareholders, the presence in person or by proxy of two or more shareholders representing in excess of 50% of the total issued voting shares of the company shall constitute a quorum for the transaction of business unless the company only has one shareholder, in which case such shareholder shall constitute a quorum. Unless otherwise required by law or by our bye-laws, shareholder action requires a resolution adopted by a majority of votes cast by shareholders at a general meeting at which a quorum is present.



## Shareholder proposals

Under Bermuda law, shareholders holding at least 5% of the total voting rights of all the shareholders having at the date of the requisition a right to vote at the meeting to which the requisition relates or any group composed of at least 100 or more shareholders may require a proposal to be submitted to an annual general meeting of shareholders. Under our bye-laws, any shareholders wishing to nominate a person for election as a director or propose business to be transacted at a meeting of shareholders must provide (among other things) advance notice, as set out in our bye-laws. Shareholders may only propose a person for election as a director at an annual general meeting.

## Shareholder action by written consent

Our bye-laws provide that, except for the removal of auditors and directors, any actions which shareholders may take at a general meeting of shareholders may be taken by the shareholders through the unanimous written consent of the shareholders who would be entitled to vote on the matter at the general meeting.

## Amendment of memorandum of association and bye-laws

Our memorandum of association and bye-laws may be amended with the approval of a majority of our board of directors and by a resolution by a majority of the votes cast by shareholders who (being entitled to do so) vote in person or by proxy at any general meeting of the shareholders in accordance with the provisions of the bye-laws.

## Business combinations

A Bermuda company may engage in a business combination pursuant to a tender offer, amalgamation, merger or sale of assets. The amalgamation or merger of a Bermuda company with another company generally requires the amalgamation or merger agreement to be approved by the company's board of directors and by its shareholders. Shareholder approval is not required where (a) a holding company and one or more of its wholly-owned subsidiary companies amalgamate or merge or (b) two or more wholly-owned subsidiary companies of the same holding company amalgamate or merge. Under the Bermuda Companies Act (save for such "short-form amalgamations"), unless a company's bye-laws provide otherwise, the approval of 75% of the shareholders voting at a meeting is required to pass a resolution to approve the amalgamation or merger agreement, and the quorum for such meeting must be two persons holding or representing more than one-third of the issued shares of the company. Our bye-laws provide that an amalgamation or merger will require the approval of our board of directors and of our shareholders by a resolution adopted by 65% or more of the votes cast by shareholders who (being entitled to do so) vote in person or by proxy at any general meeting of the shareholders in accordance with the provisions of the bye-laws. Under Bermuda law, in the event of an amalgamation or merger of a Bermuda company with another company or corporation, a shareholder who did not vote in favor of the amalgamation or merger and who is not satisfied that fair value has been offered for such shareholder's shares may, within one month of the notice of the shareholders meeting, apply to the Supreme Court of Bermuda to appraise the value of those shares.

Under the Bermuda Companies Act, we are not required to seek the approval of our shareholders for the sale of all or substantially all of our assets. However, Bermuda courts will view decisions of the English courts as highly persuasive and English authorities suggest that such sales do require shareholder approval. Our bye-laws provide that the directors shall manage the business of the Company and may exercise all such powers as are not, by the Bermuda Companies Act or by these Bye-laws, required to be exercised by the Company in general meeting and may pay all expenses incurred in promoting and incorporating the company and may exercise all the powers of the Company including, but not by way of limitation, the power to borrow money and to mortgage or charge all or any part of the undertaking property and assets (present and future) and uncalled capital of the Company and to issue debentures and other securities, whether outright or as collateral security for any debt, liability or obligation of the Company or any other persons.

Under Bermuda law, where an offer is made for shares of a company and, within four months of the offer, the holders of not less than 90% of the shares not owned by the offeror, its subsidiaries or their nominees accept such offer, the offeror may by notice require the non-tendering shareholders to transfer their shares on the terms of the offer. Dissenting shareholders do not have express appraisal rights but are entitled to seek relief (within one month of the compulsory acquisition notice) from the court, which has power to make such orders as it thinks fit. Additionally, where one or more parties hold not less than 95% of the shares of a company, such parties may, pursuant to a notice given to the remaining shareholders, acquire the shares of such remaining shareholders. Dissenting shareholders have a right to apply to the court for appraisal of the value of their shares within one month of the compulsory acquisition notice. If a dissenting shareholder is successful in obtaining a higher valuation, that valuation must be paid to all shareholders being squeezed out or the purchaser may cancel the purchase notice sent.

## Dividends and repurchase of shares

Pursuant to our bye-laws, our board of directors has the authority to declare dividends and authorize the repurchase of shares subject to applicable law. Under Bermuda law, a company may not declare or pay a dividend if there are reasonable grounds for believing that the company is, or would after the payment be, unable to pay its liabilities as they become due or the realizable value of its assets would thereby be less than its liabilities. Under Bermuda law, a company cannot purchase its own shares if there are reasonable grounds for believing that the company is, or after the repurchase would be, unable to pay its liabilities as they become due.

## Shareholder suits

Class actions and derivative actions are generally not available to



shareholders under Bermuda law. The Bermuda courts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’s memorandum of association or bye-laws. Furthermore, consideration would be given by a Bermuda court to acts that are alleged to constitute a fraud against the minority shareholders or where an act requires the approval of a greater percentage of the company’s shareholders than that which actually approved it.

When the affairs of a company are being conducted in a manner which is oppressive or prejudicial to the interests of some part of the shareholders, one or more shareholders may apply under the Bermuda Companies Act for an order of the Supreme Court of Bermuda, which may make such order as it sees fit, including an order regulating the conduct of the company’s affairs in the future or ordering the purchase of the shares of any shareholders by other shareholders or by the company.

Our bye-laws contain a provision through which we and our shareholders waive any claim or right of action that we or they have, both individually and on our behalf, against any director or officer in relation to any action or failure to take action by such director or officer, including the breach of any fiduciary duty, except in respect of any fraud or dishonesty of such director or officer.

## Comparison of Bermuda law to Delaware corporate law

## Bermuda law differs from the laws in effect in the United States and might afford less protection to shareholders.

Our shareholders could have more difficulty protecting their interests than would shareholders of a corporation incorporated in a jurisdiction of the United States. As a Bermuda company, we are governed by our memorandum of association and bye-laws and Bermuda company law. The provisions of the Bermuda Companies Act, which applies to us, differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including the provisions relating to interested directors, mergers and acquisitions, takeovers, shareholder lawsuits and indemnification of directors. Set forth below is a summary of these provisions, as well as modifications adopted pursuant to our bye-laws, which differ in certain respects from provisions of Delaware corporate law. Our shareholders approved the adoption of new bye-laws which came into effect on February 19, 2014, being the date on which the company cancelled admission of its common shares on AIM. Because the following statements are summaries, they do not discuss all aspects of Bermuda law that may be relevant to us and our shareholders.

Interested Directors. Under our bye-laws and the Bermuda Companies Act, a director shall declare the nature of his interest in any contract or arrangement with the company. Our bye-laws further provide that a director so interested shall not, except in particular circumstances, be entitled to vote or be counted in the quorum at a meeting in relation to any resolution in which he has an interest, which is to his knowledge, a material interest (otherwise than by virtue of his interest in shares or debentures or other securities of or otherwise in or through the company). A director will be liable to us for any secret profit realized from the transaction. See “Item 10—B. Memorandum of association and bye-laws—Interested Directors.”

Amalgamations, Mergers and Similar Arrangements. Pursuant to the Bermuda Companies Act, the amalgamation or merger of a Bermuda company with another company or corporation requires the amalgamation or merger agreement to be approved by the company’s board of directors and, under certain circumstances, by its shareholders. Under our bye-laws, an amalgamation or merger will require the approval of our board of directors and our shareholders by Special Resolution, which is a resolution adopted by 65% of more of the votes cast by shareholders who (being entitled to do so) vote in person or by proxy at any general meeting of the shareholders in accordance with the provisions of the bye-laws and the quorum for any general meeting must be two or more persons, in person or by proxy, representing in excess of 50% of the total of our issued voting shares. Under Bermuda law, in the event of an amalgamation or merger of a Bermuda company with another company or corporation, a shareholder of the Bermuda company who did not vote in favor of the amalgamation or merger and who is not satisfied that he has been offered fair value for his shares may, within one month of notice of the shareholders meeting, apply to the Supreme Court of Bermuda to appraise the fair value of those shares.

Under Delaware law, with certain exceptions, a merger, consolidation or sale of all or substantially all the assets of a corporation must be approved by the board of directors and a majority of the issued and outstanding shares entitled to vote thereon. Under Delaware law, a shareholder of a corporation participating in certain major corporate transactions may, under certain circumstances, be entitled to appraisal rights pursuant to which such shareholder may receive cash in the amount of the fair value of the shares held by such shareholder (as determined by a court) in lieu of the consideration such shareholder would otherwise receive in the transaction.

Shareholders’ Suit. Class actions and derivative actions are generally not available to shareholders under Bermuda law. The Bermuda courts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’s memorandum of association or bye-laws. When the affairs of a company are being conducted in a manner which is oppressive or prejudicial to the interests of some part of the shareholders, one or more shareholders may apply for an order of the Supreme Court of Bermuda regulating the conduct of the company’s affairs in the future or an order to purchase the



shares of any shareholders by other shareholders or by the company and, in the case of a purchase by the company, for the reduction accordingly of the company’s capital, or otherwise. See “Item 10—B. Memorandum of association and bye-laws—Shareholder Suits.”

Our bye-laws contain a provision by virtue of which we and our shareholders waive any claim or right of action that they have, both individually and on our behalf, against any director or officer in relation to any action or failure to take action by such director or officer, including the breach of any fiduciary duty, except in respect of any fraud or dishonesty of such director or officer. Class actions and derivative actions generally are available to shareholders under Delaware law for, among other things, breach of fiduciary duty, corporate waste and actions not taken in accordance with applicable law. In such actions, the court has discretion to permit the winning party to recover attorneys' fees incurred in connection with such action.

Indemnification of Directors. We may indemnify our directors and officers in their capacity as directors or officers for any loss arising or liability attaching to them by virtue of any rule of law in respect of any negligence, default, breach of duty or breach of trust of which a director or officer may be guilty in relation to the company other than in respect of his own fraud or dishonesty. See “Item 10—B. Memorandum of association and bye-laws—Enforcement of Judgments.” Our bye-laws provide that we shall indemnify our officers and directors in respect of their acts and omissions, except in respect of their fraud or dishonesty, or to recover any gain, personal profit or advantage to which such Director is not legally entitled, and (by incorporation of the provisions of the Bermuda Companies Act) that we may advance money to our officers and directors for the costs, charges and expenses incurred by our officers and directors in defending any civil or criminal proceedings against them on condition that the directors and officers repay the money if any allegations of fraud or dishonesty is proved against them provided, however, that, if the Bermuda Companies Act requires, an advancement of expenses shall be made only upon delivery to the Company of an undertaking, by or on behalf of such indemnitee, to repay all amounts if it shall ultimately be determined by final decision that such indemnitee is not entitled to be indemnified for such expenses under our Bye-laws or otherwise. Under Delaware law, a corporation may indemnify a director or officer of the corporation against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in defense of an action, suit or proceeding by reason of such position if such director or officer acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, such director or officer had no reasonable cause to believe his or her conduct was unlawful. In addition, we have entered into customary indemnification agreements with our directors.

As a result of these differences, investors could have more difficulty protecting their interests than would shareholders of a corporation incorporated in the United States.

Tax matters. Under current Bermuda law, we are not subject to tax on income or capital gains. We have received from the Minister of Finance under The Exempted Undertaking Tax Protection Act 1966, as amended, an assurance that, in the event that Bermuda enacts legislation imposing tax computed on profits, income, any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance, then the imposition of any such tax shall not be applicable to us or to any of our operations or shares, debentures or other obligations, until March 31, 2035. We could be subject to taxes in Bermuda after that date. This assurance is subject to the provision that it is not to be construed to prevent the application of any tax or duty to such persons as are ordinarily resident in Bermuda or to prevent the application of any tax payable in accordance with the provisions of the Land Tax Act 1967 or otherwise payable in relation to any property leased to us. We are incorporated in Bermuda as an exempted company and pay annual Bermuda government fees. In addition, all entities employing individuals in Bermuda are required to pay a payroll tax and there are other sundry taxes payable, directly or indirectly, to the Bermuda government. Neither we nor our Bermuda subsidiaries employ individuals in Bermuda as at the date of this annual report.

## Access to books and records and dissemination of information

Members of the general public have a right to inspect the public documents of a company available at the office of the Registrar of Companies in Bermuda. These documents include the company’s memorandum of association and any amendments thereto. The shareholders have the additional right to inspect the bye-laws of the company, minutes of general meetings of shareholders and the company’s audited financial statements. The company’s audited financial statements must be presented at the annual general meeting of shareholders, unless the board and all the shareholders agree to the waiving of the audited financials. The company’s share register is open to inspection by shareholders and by members of the general public without charge. A company is required to maintain its share register in Bermuda but may, subject to the provisions of the Bermuda Companies Act, establish a branch register outside of Bermuda. Bermuda law does not, however, provide a general right for shareholders to inspect or obtain copies of any other corporate records.

## Registrar or transfer agent

A register of holders of the common shares is maintained by Coson Corporate Services Limited in Bermuda, and a branch register is maintained in the United States by Computershare Trust Company, N.A., who serves as branch registrar and transfer agent.

## Enforcement of Judgments

We are incorporated as an exempted company with limited liability under the laws of Bermuda, and substantially all of our assets are located in Colombia, Chile, Brazil, Argentina and Peru. In addition, most of our



directors and executive officers reside outside the United States, and all or a substantial portion of the assets of such persons are located outside the United States. As a result, it may be difficult for investors to effect service of process on those persons in the United States or to enforce in the United States judgments obtained in U.S. courts against us or those persons based on the civil liability provisions of the U.S. securities laws.

There is no treaty in force between the United States and Bermuda providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. As a result, whether a U.S. judgment would be enforceable in Bermuda against us or our directors and officers depends on whether the U.S. court that entered the judgment is recognized by the Bermuda court as having jurisdiction over us or our directors and officers, as determined by reference to Bermuda conflict of law rules and the judgment is not contrary to public policy in Bermuda, has not been obtained by fraud in proceedings contrary to natural justice and is not based on an error in Bermuda law. A judgment debt from a U.S. court that is final and for a sum certain based on U.S. federal securities laws will not be enforceable in Bermuda unless the judgment debtor had submitted to the jurisdiction of the U.S. court, and the issue of submission and jurisdiction is a matter of Bermuda (not U.S.) law.

An action brought pursuant to a public or penal law, the purpose of which is the enforcement of a sanction, power or right at the instance of the state in its sovereign capacity, may not be entertained by a Bermuda court. Certain remedies available under the laws of U.S. jurisdictions, including certain remedies under U.S. federal securities laws, may not be available under Bermuda law or enforceable in a Bermuda court, as they may be contrary to Bermuda public policy. Further, no claim may be brought in Bermuda against us or our directors and officers in the first instance for violations of U.S. federal securities laws because these laws have no extraterritorial jurisdiction under Bermuda law and do not have force of law in Bermuda. A Bermuda court may, however, impose civil liability on us or our directors and officers if the facts alleged in a complaint constitute or give rise to a cause of action under Bermuda law. However, section 281 of the Bermuda Companies Act allows a Bermuda court, in certain circumstances, to relieve officers and directors of Bermuda companies of liability for acts of negligence, breach of duty or trust or other defaults.

Section 98 of the Bermuda Companies Act provides generally that a Bermuda company may indemnify its directors, officers and auditors against any liability which by virtue of any rule of law would otherwise be imposed on them in respect of any negligence, default, breach of duty or breach of trust, except in cases where such liability arises from fraud or dishonesty of which such director, officer or auditor may be guilty in relation to the company. Section 98 further provides that a Bermuda company may indemnify its directors, officers and auditors against any liability incurred by them in defending any proceedings, whether civil or criminal, in which judgment is awarded in their favor or in which they are acquitted or granted relief by the Supreme Court of Bermuda pursuant to Section 281 of the Bermuda Companies Act.
Our bye-laws contain provisions whereby we and our shareholders waive any claim or right of action that we have, both individually and on our behalf, against any director or officer in relation to any action or failure to take action by such director or officer, except in respect of any fraud or dishonesty of such director or officer. We may also indemnify our directors and officers in their capacity as directors and officers for any loss arising or liability attaching to them by virtue of any rule of law in respect of any negligence, default, breach of trust of which a director or officer may be guilty in relation to the company other than in respect of his own fraud or dishonesty. We have entered into customary indemnification agreements with our directors.

No treaty exists between the United States and Chile for the reciprocal recognition and enforcement of foreign judgments. Chilean courts, however, have enforced valid and conclusive judgments for the payment of money rendered by competent U.S. courts by virtue of the legal principles of reciprocity and comity, subject to review in Chile of the U.S. judgment in order to ascertain whether certain basic principles of due process and public policy have been respected, without retrial or review of the merits of the subject matter. If a U.S. court grants a final judgment, enforceability of this judgment in Chile will be subject to obtaining the relevant exequatur (i.e., recognition and enforcement of the foreign judgment) according to Chilean civil procedure law in effect at that time, and depending on certain factors (the satisfaction or non-satisfaction of which would be determined by the Supreme Court of Chile). Currently, the most important of such factors are: the existence of reciprocity (if it can be proved that there is no reciprocity in the recognition and enforcement of the foreign judgment between the United States and Chile, that judgment would not be enforced in Chile); the absence of any conflict between the foreign judgment and Chilean laws (excluding for this purpose the laws of civil procedure) and Chilean public policy; the absence of a conflicting judgment by a Chilean court relating to the same parties and arising from the same facts and circumstances; the Chilean court's determination that the U.S. courts had jurisdiction, that process was appropriately served on the defendant and that the defendant was afforded a real opportunity to appear before the court and defend its case; and the judgment being final under the laws of the country in which it was rendered. Nonetheless, we have been advised by our Chilean counsel that there is doubt as to the enforceability in original actions in Chilean courts of liabilities predicated solely upon U.S. federal or state securities laws.

## C. Material contracts

See “Item 4. Information on the Company—B. Business Overview—Significant Agreements.”

## D. Exchange controls

Not applicable.

## E. Taxation

The following summary contains a description of certain Bermudian, U.S. federal income, and Chilean tax consequences of the acquisition, ownership and



disposition of our common shares. The summary is based upon the tax laws of Bermuda, the United States, and Chile, and regulations thereunder as of the date hereof, which are subject to change.

## Bermuda tax consideration

At the date of this annual report, there is no Bermuda income or profits tax, withholding tax, capital gains tax, capital transfer tax, estate duty or inheritance tax payable by us or by our shareholders in respect of our common shares. We have obtained an assurance from the Minister of Finance of Bermuda under the Exempted Undertakings Tax Protection Act 1966 that, in the event that any legislation is enacted in Bermuda imposing any tax computed on profits or income, or computed on any capital asset, gain or appreciation or any tax in the nature of estate duty or inheritance tax, such tax shall not, until March 31, 2035, be applicable to us or to any of our operations or to our common shares, debentures or other obligations except insofar as such tax applies to persons ordinarily resident in Bermuda or is payable by us in respect of real property owned or leased by us in Bermuda. We pay annual Bermuda government fees.

## Material U.S. federal income tax considerations

The following is a description of the material U.S. federal income tax consequences to U.S. Holders (as defined below) of owning and disposing of our common shares. This discussion is not a comprehensive description of all tax considerations that may be relevant to a particular person's decision to hold our common shares. This discussion applies only to a U.S. Holder that holds our common shares as capital assets for tax purposes. In addition, it does not describe all of the tax consequences that may be relevant in light of the U.S. Holder's particular circumstances, including alternative minimum tax and Medicare contribution tax consequences and differing tax consequences applicable to a U.S. Holder subject to special rules, such as:

• certain financial institutions;

• a dealer or trader in securities who uses a mark-to-market method of tax accounting;

• a person holding common shares as part of a straddle, wash sale or conversion transaction or entering into a constructive sale with respect to the common shares;

• a person whose functional currency for U.S. federal income tax purposes is not the US$;

• a partnership or other entities classified as partnerships for U.S. federal income tax purposes;

• a tax-exempt entity, including an “individual retirement account” or “Roth IRA;”

• a person that owns or is deemed to own 10% or more of our shares by vote or value;

• a person who acquired our shares pursuant to the exercise of an employee stock option or otherwise as compensation; or

• a person holding common shares in connection with a trade or business conducted outside of the United States.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds common shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding common shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of their investment in our common shares.

This discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), administrative pronouncements, judicial decisions, and final, temporary and proposed Treasury regulations, all as of the date hereof, any of which is subject to change, possibly with retroactive effect. U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and foreign tax consequences of owning and disposing of our common shares in their particular circumstances.

A “U.S. Holder” is a beneficial owner of our common shares for U.S. federal income tax purposes that is:

• a citizen or individual resident of the United States;

• a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

• an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

This discussion assumes that we are not, and will not become, a passive foreign investment company, as described below.

## Taxation of distributions

Distributions paid on our common shares, other than certain pro rata distributions of common shares, will generally be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions will generally be reported to U.S. Holders as dividends. Subject to the passive foreign investment company rules described below, dividends paid by qualified foreign corporations to certain noncorporate U.S. Holders may be taxable at favorable rates. A foreign corporation is treated as a qualified foreign corporation with respect to dividends paid on stock that is readily tradable on a securities market in the United States, such as the NYSE where our common shares are traded. Non-corporate U.S. Holders should consult their tax advisers to determine whether the favorable rate will apply to dividends they receive and whether they are subject to any special rules that limit their ability to be taxed at this favorable rate.

A dividend generally will be included in a U.S. Holder’s income when received, will be treated as foreign-source income to U.S. Holders and will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code with respect to dividends paid by domestic corporations.

Sale or other taxable disposition of common shares



Gain or loss realized on the sale or other taxable disposition of our common shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held our common shares for more than one year. Long-term capital gain of a non-corporate U.S. Holder is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations. The amount of the gain or loss will equal the difference between the U.S. Holder's tax basis in the common shares disposed of and the amount realized on the disposition. If a Chilean tax is withheld on the sale or disposition of common shares, a U.S. Holder's amount realized will include the gross amount of the proceeds of the sale or disposition before deduction of the Chilean tax. See "—Chilean tax on transfers of shares" for a description of when a disposition may be subject to taxation by Chile. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. U.S. Holders should consult their tax advisers as to whether the Chilean tax on gains may be creditable against the U.S. Holder's U.S. federal income tax on foreign-source income from other sources.

## Passive foreign investment company rules

We believe that we were not a “passive foreign investment company,” or PFIC, for U.S. federal income tax purposes for 2018, and we do not expect to be a PFIC in the foreseeable future. However, because the composition of our income and assets will vary over time, there can be no assurance that we will not be a PFIC for any taxable year. The determination of whether we are a PFIC is made annually and is based upon the composition of our income and assets (including the income and assets of, among others, entities in which we hold at least a 25% interest), and the nature of our activities.

If we were a PFIC for any taxable year during which a U.S. Holder held our common shares, gain recognized by a U.S. Holder on a sale or other disposition (including certain pledges) of our common shares would generally be allocated ratably over the U.S. Holder's holding period for the common shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations for that year, as appropriate, and an interest charge would be imposed on the tax on such amount. Further, to the extent that any distribution received by a U.S. Holder on its common shares exceeds 125% of the average of the annual distributions on the shares received during the preceding three years or the U.S. Holder's holding period, whichever is shorter, that distribution would be subject to taxation in the same manner as gain, as described immediately above. Certain elections may be available that would result in alternative treatments (such as mark-to-market treatment) of our common shares. U.S. Holders should consult their tax advisers to determine whether any of these elections would be available and, if so, what the consequences of the alternative treatments would be in their particular circumstances.

Furthermore, if we were a PFIC or, with respect to a particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

## Information reporting and backup withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (1) the U.S. Holder is a corporation or other exempt recipient or (2) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder's U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the Internal Revenue Service.

## Chilean tax on transfers of shares

In September 2012, Article 10 of the Chilean Income Tax Law Decree Law No. 824 of 1974, or the indirect transfer rules, were enacted, and impose taxes on the indirect transfer of shares, equity rights, interests or other rights in the equity, control or profits of a Chilean entity as well as transfers of other assets and property of permanent establishments or other businesses in Chile. Reforms introduced in 2014 imposed a measure which obliges the company from which shares are transferred to pay taxes if the entity which undertakes the transfer of shares fails to do so.

## The indirect transfer rules apply to sales of shares of an entity:

- If such entity is an offshore holding company located in a black-listed tax haven jurisdiction as determined by Chilean tax law, or a black-listed jurisdiction, (such as Bermuda) that holds Chilean Assets; and either a Chilean resident holds 5% or more of such entity, or such entity's rights to equity, control or profits, or 50% or more of such entity's rights to equity or profits are held by residents in black-listed jurisdictions; or

- the shares or rights transferred represent 10% or more of the offshore holding company (considering dispositions by related persons and over the preceding 12-month period) and the underlying Chilean Assets indirectly transferred, in the proportion indirectly owned by the seller, (a) are valued in an amount equal to or higher than UTA 210,000 (approximately US$200 million) (adjusted by the Chilean inflation unit of reference) or (b) represent 20% or more of the market value of the interest held by such seller in such offshore holding company.

As a result of these rules, a capital gain tax of 35% will be applied by the Chilean tax authorities to the sale of any of our common shares if either of the above tests are met. This rate might be subject to change in the short term. See "Item 4. Information on the Company—B. Business overview—Industry and regulatory framework—Chile."

As of December 31, 2018, our Chilean Assets represented more than UTA 210,000 and represent more than 32% of our total assets.



The 35% rate is calculated pursuant to one of the following methods, as determined by the seller:

• the sale price of the shares minus the acquisition cost of such shares, multiplied by the percentage or proportion of the part of the underlying Chilean Assets' fair market value (which assets are deemed to be "indirectly transferred" by virtue of the sale of shares) to the fair market value of the shares of the seller; or

• the portion of the sales price of the shares equal to the proportion of the fair market value of the underlying Chilean Assets, minus the corresponding proportion in the tax cost of such Chilean Assets for the corresponding holding entity.

However, the seller may opt to be taxed as if the underlying Chilean Assets had been sold directly in which case a different set of tax rules may apply.

The tax is payable by the seller of the shares; however, the buyer shall make a provisional withholding unless the seller declares and pays the tax within the month following the sale, payment, remittance or it is credited into its account or is put at its disposal. Also, if the seller fails to declare and pay this tax, and the buyer has not complied with its withholding obligations, the Chilean tax authority (Servicio de Impuestos Internos) may charge such tax directly to any of them. In addition, the Chilean tax authority may require us, the seller, the buyer, or its representative in Chile, to file an affidavit with the information necessary to assess this tax.

Based on information available to us, (i) no Chilean resident holds 5% or more of our rights to equity, control or profits; and (ii) residents in black-listed jurisdictions do not hold 50% or more of our rights to equity, control or profits. Therefore, we do not believe the indirect transfer rules will apply to transfers of our common shares, unless the shares or rights transferred represent 10% or more of the company and the other conditions described above are met (considering dispositions by related persons and over the preceding 12-month period).

However, there can be no assurance that, at any time in the future, a Chilean resident will not hold 5% or more of our rights to equity, control or profits or that residents in black-listed jurisdictions will not hold 50% or more of our rights to equity, control or profits. If this were to occur, all sales of our common shares would be subject to the indirect transfer tax referred to above.

Our expectations regarding the indirect transfer rules are based on our understandings, analysis and interpretation of these enacted indirect transfer rules, which are subject to additional interpretation and rule-making by the Chilean authorities. As such, there is uncertainty relating to the application by Chilean authorities of the indirect transfer rules on us.

See “Item 3. Key Information—D. Risk Factors—Risks related to our common shares—The transfer of our common shares may be subject to capital gains taxes pursuant to indirect transfer rules in Chile.”

## ITEM 15. CONTROLS AND PROCEDURES

## A. Disclosure Controls and Procedures

As of December 31, 2018, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). There are inherent limitations to the effectiveness of any disclosure controls and procedures system, including the possibility of human error and circumventing or overriding them. Even if effective, disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives.

Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that the information we are required to disclose in the reports we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and (2) accumulated and communicated to our management to allow timely decisions regarding required disclosures.

## B. Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining an adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act.

Our internal control over financial reporting is a process designed by, or under the supervision of, our principal executive and principal financial officers, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes, in accordance with generally accepted accounting principles. These include those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of our assets;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements, in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorization of our management and directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, effective control over financial reporting cannot, and does not, provide absolute assurance of achieving our control objectives. Also, projections of, and any evaluation of effectiveness of the internal controls in future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer, our Chief Financial Officer, and our Director of Legal and Governance, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2018, based on the criteria established in Internal Control - Integrated Framework of the Committee of Sponsoring Organizations of the Treadway Commission (2013).

Based on this assessment, management believes that, as of December 31, 2018, its internal control over financial reporting was effective based on those criteria.

## C. Attestation Report of the Registered Public Accounting Firm

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2018, has been audited by Price Waterhouse & Co. S.R.L., an independent registered public accounting firm, as stated in their report which is included on page F-2 of our Consolidated Financial Statements herein.

## D. Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the period covered by this annual report on Form 20-F that have materially affected or reasonably likely to materially affect our internal control over financial reporting.

## ITEM 16. RESERVED

## ITEM 16A. Audit committee financial expert

We have determined that Mr. Juan Cristóbal Pavez, Mr. Constantine Papadimitriou and Mr. Robert Bedingfield are independent, as such term is defined under SEC rules applicable to foreign private issuers. In addition, Mr. Robert Bedingfield is regarded as audit committee financial expert.

## ITEM 16B. Code of Conduct

We have adopted a code of conduct applicable to the board of directors and all employees. Since its effective date on September 24, 2012, we have not waived compliance with or amended the code of conduct.

## ITEM 16C. Principal Accountant Fees and Services



Amounts billed by PwC for audit and other services were as follows:

<table><tr><td></td><td>2018</td><td>2017</td></tr><tr><td></td><td colspan="2">(in millions of US$)</td></tr><tr><td>Audit fees</td><td>0.80</td><td>0.73</td></tr><tr><td>Audit related fees</td><td>-</td><td>0.14</td></tr><tr><td>Tax services fees</td><td>0.21</td><td>0.21</td></tr><tr><td>Other fees paid</td><td>-</td><td>0.03</td></tr><tr><td>Total</td><td>1.01</td><td>1.11</td></tr></table>

## Audit Fees

Audit fees are fees billed for professional services rendered by the principal accountant for the audit of the registrant's annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements for those fiscal years. It includes the audit of our Consolidated Financial Statements and other services that generally only the independent accountant reasonably can provide, such as comfort letters, statutory audits, consents and assistance with and review of documents filed with the SEC.

## Audit-Related Fees

Audit-related fees are fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our Consolidated Financial Statements and not reported under the previous category. These services would include, among others: accounting consultations and audits in connection with acquisitions, internal control reviews, attest services that are not required by statute or regulation and consultation concerning financial accounting and reporting standards.

## Tax Fees

Tax fees are fees billed for professional services for tax compliance, tax advice and tax planning.

## Pre-Approval Policies and Procedures

Following the listing of our common shares on the NYSE, the Audit Committee proposes the appointment of the independent auditor to the Board to be put to shareholders for approval at the Annual General meeting. The committee oversees the auditor selection process for new auditors and ensures key partners in the appointed firm are rotated in accordance with best practices. Also, following our NYSE listing, the Audit Committee is required to pre-approve the audit and non-audit fees and services performed by the Company's auditors in order to be sure that the provision of such services does not impair the audit firm's independence.

All of the audit fees, audit-related fees and tax fees described in this item 16C have been approved by the Audit Committee.

ITEM 16D. Exemptions from the listing standards for audit committees None.

## ITEM 16E. Purchases of equity securities by the issuer and affiliated purchasers.

The following table presents purchases of our common shares by the company and “affiliated purchasers” (as that term is defined in Rule 10b-18(a)(3) under the Securities Exchange Act of 1934, as amended) during 2018:

<table><tr><td></td><td>Total Number of Shares Purchased</td><td>Average Price Paid per Share</td><td>Part of Publicly Announced Plans or Programs</td><td>Maximum Number (or Approximate Dollar Value) of Shares that May Yet be Purchased Under the Plans or Programs</td></tr><tr><td>December 21 to December 31, 2018</td><td>145,917</td><td>12.0</td><td>145,917</td><td>6,063,000 shares</td></tr></table>

## ITEM 16F. Change in registrant's certifying accountant

Not applicable.

## ITEM 16G. Corporate governance

Our common shares are listed on the NYSE. We are therefore required to comply with certain of the NYSE's corporate governance listing standards (the "NYSE Standards"). As a foreign private issuer, we may follow our home country's corporate governance practices in lieu of most of the NYSE Standards. Our corporate governance practices differ in certain significant respects from those that U.S. companies must adopt in order to maintain NYSE listing and, in accordance with Section 303A.11 of the NYSE Listed Company Manual, a brief, general summary of those differences is provided as follows.

## Director independence

The NYSE Standards require a majority of the membership of NYSE-listed company boards to be composed of independent directors. Neither Bermuda law, the law of our country of incorporation, nor our memorandum of association or bye-laws require a majority of our board to consist of independent directors.

## Non-management directors' executive sessions

The NYSE Standards require non-management directors of NYSE-listed companies to meet at regularly scheduled executive sessions without management. Our memorandum of association and bye-laws do not require our non-management directors to hold such meetings.

## Committee member composition

The NYSE Standards require domestic NYSE-listed domestic companies to have a nominating/corporate governance committee and a compensation



committee that are composed entirely of independent directors. Bermuda law, the law of our country of incorporation, does not impose similar requirements.

## Independence of the compensation committee and its advisers

On January 11, 2013, the SEC approved NYSE listing standards that require that the board of directors of a domestic listed company consider two factors (in addition to the existing general independence tests) in the evaluation of the independence of compensation committee members: (i) the source of compensation of the director, including any consulting, advisory or other compensatory fees paid by the listed company, and (ii) whether the director has an affiliate relationship with the listed company, a subsidiary of the listed company or an affiliate of a subsidiary of the listed company. In addition, before selecting or receiving advice from a compensation consultant or other adviser, the compensation committee of a listed company will be required to take into consideration six specific factors, as well as all other factors relevant to an adviser's independence.

Foreign private issuers such as us will be exempt from these requirements if home country practice is followed. Bermuda law does not impose similar requirements, so we will not be required to implement the NYSE listing standards relating to compensation committees of domestic listed companies. All of the members of our compensation committee are independent, and the charter of our compensation committee does not require the compensation committee to consider the independence of any advisers that assist them in fulfilling their duties.

## Additional audit committee functions

The NYSE standards require that audit committees of domestic companies to serve a number of functions in addition to reviewing and approving the company's financial statements, engaging auditors and assessing their independence, and obtaining the legal and other professional advice of experts when necessary. For instance, the NYSE Standards require that the audit committee meet independently with management in a separate session in order to maximize the effectiveness of the committee's oversight function. In addition, audit committees must obtain and review a report by the independent auditors describing the firm's internal quality-control procedures and any issues raised by these procedures. Finally, audit committees are responsible for designing and implementing an internal audit function that assesses the company's risk management processes and systems of internal control on an ongoing basis.

Foreign private issuers such as us are exempt from these additional requirements if home country practice is followed. Bermuda law does not impose similar requirements, and consequently, our audit committee does not perform these additional functions. Our Audit Committee is composed exclusively of independent auditors.

## Miscellaneous

In addition to the above differences, we are not required to: make our audit and compensation committees prepare a written charter that addresses either purposes and responsibilities or performance evaluations in a manner that would satisfy the NYSE's requirements; acquire shareholder approval of equity compensation plans in certain cases; or adopt and make publicly available corporate governance guidelines.

We are incorporated under, and are governed by, the laws of Bermuda.

The terms defined in this section are used throughout this annual report: "appraisal well" means a well drilled to further confirm and evaluate the presence of hydrocarbons in a reservoir that has been discovered.

“API” means the American Petroleum Institute’s inverted scale for denoting the “light” or “heaviness” of crude oils and other liquid hydrocarbons.

“bbl” means one stock tank barrel, of 42 U.S. gallons liquid volume, used herein in reference to crude oil, condensate or natural gas liquids.

“bcf” means one billion cubic feet of natural gas.

“bcm” means billion cubic meters.

“boe” means barrels of oil equivalent, with 6,000 cubic feet of natural gas being equivalent to one barrel of oil.

“boepd” means barrels of oil equivalent per day.

“bopd” means barrels of oil per day.

“British thermal unit” or “btu” means the heat required to raise the temperature of a one-pound mass of water from 58.5 to 59.5 degrees Fahrenheit.

“basin” means a large natural depression on the earth’s surface in which sediments generally brought by water accumulate.

“CEOP” (Contrato Especial de Operación) means a special operating contract the Chilean signs with a company or a consortium of companies for the exploration and exploitation of hydrocarbon wells

“completion” means the process of treating a drilled well followed by the installation of permanent equipment for the production of natural gas or oil, or in the case of a dry hole, the reporting of abandonment to the appropriate agency.

“developed acreage” means the number of acres that are allocated or assignable to productive wells or wells capable of production.

“developed reserves” are expected quantities to be recovered from existing wells and facilities. Reserves are considered developed only after the necessary equipment has been installed or when the costs to do so are relatively minor compared to the cost of a well. Where required facilities become unavailable, it may be necessary to reclassify developed reserves as undeveloped.

“development well” means a well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive. “dry hole” means a well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production exceed production expenses and taxes.

“E&P Contract” means exploration and production contract “economic interest” means an indirect participation interest in the net revenues from a given block based on bilateral agreements with the concessionaires.

“economically producible” means a resource that generates revenue that exceeds, or is reasonably expected to exceed, the costs of the operation. “exploratory well” means a well drilled to find and produce oil or gas in an unproved area, to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir, or to extend a known reservoir. Generally, an exploratory well is any well that is not a development well, a service well, or a stratigraphic test well as those items are defined below. “field” means an area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same individual geological structural feature and/or stratigraphic condition. There may be two or more reservoirs in a field that are separated vertically by intervening impervious strata, or laterally by local geologic barriers, or by both. Reservoirs that are associated by being in overlapping or adjacent fields may be treated as a single or common operational field. The geological terms structural feature and stratigraphic condition are intended to identify localized geological features as opposed to the broader terms of basins, trends, provinces, plays, areas-of-interest, etc. “formation” means a layer of rock which has distinct characteristics that differ from nearby rock.

“mbbl” means one thousand barrels of crude oil, condensate or natural gas liquids.

“mboe” means one thousand barrels of oil equivalent.

“mcf” means one thousand cubic feet of natural gas.

“Measurements” include:

• “m” or “meter” means one meter, which equals approximately 3.28084 feet;

• “km” means one kilometer, which equals approximately 0.621371 miles;

• “sq. km” means one square kilometer, which equals approximately 247.1 acres;

• “bbl”“bo,” or “barrel of oil” means one stock tank barrel, which is equivalent to approximately 0.15898 cubic meters;

• “boe” means one barrel of oil equivalent, which equals approximately 160.2167 cubic meters, determined using the ratio of 6,000 cubic feet of natural gas to one barrel of oil;

• “cf” means one cubic foot;

• “m,” when used before bbl, boe or cf, means one thousand bbl, boe or cf, respectively;

• “mm,” when used before bbl, boe or cf, means one million bbl, boe or cf, respectively;

• “b,” when used before bbl, boe or cf, means one billion bbl, boe or cf, respectively; and

• “pd” means per day.

“metric ton” or “MT” means one thousand kilograms. Assuming standard quality oil, one metric ton equals 7.9 bbl.

“mmbbl” means one million barrels of crude oil, condensate or natural gas liquids.
“mmboe” means one million barrels of oil equivalent.

“mmbtu” means one million British thermal units.

“NYMEX” means The New York Mercantile Exchange.

“net acres” means the percentage of total acres an owner has out of a particular number of acres, or a specified tract. An owner who has a 50% interest in 100 acres owns 50 net acres.

“productive well” means a well that is found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of the production exceed production expenses and taxes.

“prospect” means a potential trap which may contain hydrocarbons and is supported by the necessary amount and quality of geologic and geophysical data to indicate a probability of oil and/or natural gas accumulation ready to be drilled. The five required elements (generation, migration, reservoir, seal and trap) must be present for a prospect to work and if any of them fail neither



oil nor natural gas will be present, at least not in commercial volumes. "proved developed reserves" means those proved reserves that can be expected to be recovered through existing wells and facilities and by existing operating methods.

“proved reserves” means estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be economically recoverable in future years from known reservoirs under existing economic and operating conditions, as well as additional reserves expected to be obtained through confirmed improved recovery techniques, as defined in SEC Regulation S-X 4-10(a)(2).

“proved undeveloped reserves” means are those proved reserves that are expected to be recovered from future wells and facilities, including future improved recovery projects which are anticipated with a high degree of certainty in reservoirs which have previously shown favorable response to improved recovery projects.

“reasonable certainty” means a high degree of confidence.

“recompletion” means the process of re-entering an existing wellbore that is either producing or not producing and completing new reservoirs in an attempt to establish or increase existing production.

“reserves” means estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, a revenue interest in the production, installed means of delivering oil, gas, or related substances to market, and all permits and financing required to implement the project.

“reservoir” means a porous and permeable underground formation containing a natural accumulation of producible oil and/or gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs.

“royalty” means a fractional undivided interest in the production of oil and natural gas wells or the proceeds therefrom, to be received free and clear of all costs of development, operations or maintenance.

“service well” means a well drilled or completed for the purpose of supporting production in an existing field. Specific purposes of service wells include gas injection, water injection, steam injection, air injection, saltwater disposal, water supply for injection, observation, or injection for in-situ combustion. “shale” means a fine grained sedimentary rock formed by consolidation of clay- and silt-sized particles into thin, relatively impermeable layers. Shale can include relatively large amounts of organic material compared with other rock types and thus has the potential to become rich hydrocarbon source rock. Its fine grain size and lack of permeability can allow shale to form a good cap rock for hydrocarbon traps.

“spacing” means the distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres (e.g., 40-acre spacing, and is often established by regulatory agencies).

“spud” means the very beginning of drilling operations of a new well, occurring when the drilling bit penetrates the surface utilizing a drilling rig capable of drilling the well to the authorized total depth.
“stratigraphic test well” means a drilling effort, geologically directed, to obtain information pertaining to a specific geologic condition. Such wells customarily are drilled without the intention of being completed for hydrocarbon production. This classification also includes tests identified as core tests and all types of expendable holes related to hydrocarbon exploration. Stratigraphic test wells are classified as (i) exploratory-type, if not drilled in a proved area, or (ii) development-type, if drilled in a proved area.

“tcm” means trillion cubic meters.

“undeveloped reserves” are quantities expected to be recovered through future investments: (1) from new wells on undrilled acreage in known accumulation, (2) from deepening existing wells to a different (but known) reservoir, (3) from infill wells that will increase recover, or (4) where a relatively large expenditure (e.g., when compared to the cost of drilling a new well) is required to (a) recomplete an existing well or (b) install production or transportation facilities for primary or improved recovery projects.

“unit” means the joining of all or substantially all interests in a reservoir or field, rather than a single tract, to provide for development and operation without regard to separate property interests. Also, the area covered by a unitization agreement.

“wellbore” means the hole drilled by the bit that is equipped for oil or gas production on a completed well. Also called well or borehole.

“working interest” means the right granted to the lessee of a property to explore for and to produce and own oil, gas, or other minerals. The working interest owners bear the exploration, development, and operating costs on either a cash, penalty, or carried basis.

“workover” means operations in a producing well to restore or increase production.

## Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statement of financial position of GeoPark Limited and its subsidiaries (the "Company") as of December 31, 2018 and 2017, the related consolidated statements of income and of comprehensive income, changes in equity and cash flows, for each of the three years in the period ended December 31, 2018, including the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

## Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.

## Note 1

## General Information

GeoPark Limited (the "Company") is a company incorporated under the law of Bermuda. The Registered Office address is Cumberland House, 9th Floor, 1 Victoria Street, Hamilton HM11, Bermuda.

The principal activities of the Company and its subsidiaries (the "Group" or "GeoPark") are exploration, development and production for oil and gas reserves in Colombia, Chile, Brazil, Argentina and Peru.

These Consolidated Financial Statements were authorized for issue by the Board of Directors on 6 March 2019.

## Note 2

## Summary of significant accounting policies

The principal accounting policies applied in the preparation of these Consolidated Financial Statements are set out below. These policies have been consistently applied to the years presented, unless otherwise stated.

## 2.1 Basis of preparation

The Consolidated Financial Statements of GeoPark Limited have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"), under the historical cost convention.

The Consolidated Financial Statements are presented in thousands of United States Dollars (US$'000) and all values are rounded to the nearest thousand (US$'000), except in the footnotes and where otherwise indicated.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Group's accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the Consolidated Financial Statements are disclosed in this note under the title "Accounting estimates and assumptions".

All the information included in these Consolidated Financial Statements corresponds to the Group, except where otherwise indicated.

## 2.1.1 Changes in accounting policy and disclosure

New and amended standards adopted by the Group

The following standards have been adopted by the Group for the first time for the financial year beginning on or after 1 January 2018:

• IFRS 9 Financial Instruments

• IFRS 15 Revenue from Contracts with Customers

• Classification and Measurement of Share-based Payment Transactions – Amendments to IFRS 2

• Annual Improvements 2014-2016 cycle

• Interpretation 22 Foreign Currency Transactions and Advance Consideration

The Group also elected to adopt the following amendments early:

• Annual Improvements to IFRS Standards 2015-2017 Cycle.

IFRS 9 replaces the provisions of IAS 39 related to the recognition, classification and measurement of financial assets and financial liabilities, derecognition of financial instruments, impairment of financial assets and hedge accounting.

The adoption of IFRS 9 from 1 January 2018 resulted in changes in accounting policies (see Note 2.16 and Note 2.18) and a reclassification of a measurement category (see below), but no adjustments to the amounts recognized in the Consolidated Financial Statements.

On 1 January 2018, the Group classified money market funds for US$ 44,123,000 accounted within Cash and cash equivalents as of 31 December 2017, as Financial assets at fair value through profit or loss that were previously classified as Loans and receivables. No results were generated as a consequence of this change. As of 31 December 2018, the Group holds money market funds for US$ 53,794,000.

IFRS 15 replaces IAS 18 which covered contracts for goods and services and IAS 11 which covered construction contracts. The new standard is based on the principle that revenue is recognized when control of a good or service transfers to a customer, so the notion of control replaces the existing notion of risks and rewards.

The adoption of IFRS 15 from 1 January 2018 resulted in no changes in accounting policies or adjustments to the amounts recognized in the Consolidated Financial Statements.

The adoption of the other amendments listed above did not have any impact on the amounts recognized in prior periods and are not expected to significantly affect the current or future periods.

New standards, amendments and interpretations issued but not effective for the financial year beginning 1 January 2018 and not early adopted.

• IFRS 16 Leases: will affect primarily the accounting by lessees and will result in the recognition of almost all leases on the balance sheet. The standard removes the current distinction between operating and financing leases and requires recognition of an asset (the right to use the leased item) and a financial liability to pay rentals for virtually all lease contracts. An optional exemption exists for short-term and low-value leases. The accounting by



lessors will not significantly change. Some differences may arise as a result of the new guidance on the definition of a lease.

The Group has set up a project team by business unit which has reviewed each business unit’s leasing arrangements over the last year in light of the new lease accounting rules in IFRS 16. The standard will affect primarily the accounting for the Group’s operating leases.

As at the reporting date, the Group has non-cancellable operating lease commitments of US$ 69,938,000, see Note 32.3. Of these commitments, the Group expects to recognize right-of-use assets and lease liabilities, at nominal value, of approximately US$ 14,449,000 on 1 January 2019. The remaining lease commitments, in accordance with IFRS 16, will be recognized on a straight-line basis as expense in the Consolidated Statement of Income.

There will not be an impact on Adjusted EBITDA as a consequence of the adoption of this new standard. This measure is used to assess the performance of the operating segments and is also considered for the calculation of the incurrence test covenants included in the indenture governing the Group's main financial debt. Therefore, Management decided to modify the definition of this measure since the adoption of IFRS 16 in 2019 in order to ensure comparability with previous periods.

Operating cash flows will increase and financing cash flows decrease by approximately US$ 4,000,000 as repayment of the principal portion of the lease liabilities will be classified as cash flows from financing activities.

The Group will apply the standard from its mandatory adoption date of 1 January 2019. The Group intends to apply the simplified transition approach and will not restate comparative amounts for the year prior to first adoption. Lease liability for property leases will be measured on transition at the present value of the remaining lease payments, discounted using the lessee's incremental borrowing rate at the date of initial application. The right-of-use asset on transition (on a lease-by-lease basis) will be measure at an amount equal to the lease liability (adjusted for any prepaid or accrued lease expenses).

There are no other standards that are not yet effective and that would be expected to have a material impact on the entity in the current or future reporting periods and on foreseeable future transactions.

## 2.2 Going concern

The Directors regularly monitor the Group’s cash position and liquidity risks throughout the year to ensure that it has sufficient funds to meet forecast operational and investment funding requirements. Sensitivities are run to reflect latest expectations of expenditures, oil and gas prices and other factors to enable the Group to manage the risk of any funding short falls and/or potential debt covenant breaches.
Considering macroeconomic environment conditions, the performance of the operations, the US$ 425,000,000 debt fundraising completed in September 2017, the Group’s cash position, and the fact that over 95% of its total indebtedness matures in 2024, the Directors have formed a judgement, at the time of approving the financial statements, that there is a reasonable expectation that the Group has adequate resources to meet all its obligations for the foreseeable future. For this reason, the Directors have continued to adopt the going concern basis in preparing the Consolidated Financial Statements.

## 2.3 Consolidation

Subsidiaries are all entities (including structured entities) over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred by the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired, and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. Acquisition-related costs are expensed as incurred.

The excess of the consideration transferred over the fair value of the identifiable net assets acquired is recorded as goodwill. If the total of consideration transferred is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

Intercompany transactions, balances and unrealized gains on transactions between the Group and its subsidiaries are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Amounts reported in the financial statements of subsidiaries have been adjusted where necessary to ensure consistency with the accounting policies adopted by the Group.

## 2.4 Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Executive Committee. This committee is integrated by the CEO, COO, CFO and managers in charge of the Geoscience, Operations, Corporate Governance, Finance and



People departments. This committee reviews the Group’s internal reporting in order to assess performance and allocate resources. Management has determined the operating segments based on these reports.

## 2.5 Foreign currency translation

## 2.5.1. Functional and presentation currency

The Consolidated Financial Statements are presented in US Dollars, which is the Group’s presentation currency.

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of Group companies incorporated in Chile, Colombia, Peru and Argentina is the US Dollar, meanwhile for the Group’s Brazilian company the functional currency is the local currency, which is the Brazilian Real.

## 2.5.2. Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the Consolidated Statement of Income.

## 2.6 Joint arrangements

Under IFRS 11 investments in joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor.

The Group has assessed the nature of its joint arrangements and determined them to be joint operations. The Group combines its share in the joint operations individual assets, liabilities, results and cash flows on a line-by-line basis with similar items in its financial statements.

## 2.7 Revenue recognition

Revenue from the sale of crude oil and gas is recognized in the Consolidated Statement of Income when control is transferred to the purchaser, and if the revenue can be measured reliably and is expected to be received. Revenue is shown net of VAT, discounts related to the sale and overriding royalties due to the ex-owners of oil and gas properties where the royalty arrangements represent a retained working interest in the property. See Note 32.1.

## 2.8 Production and operating costs

Production and operating costs are recognized in the Consolidated Statement of Income on the accrual basis of accounting. These costs include wages and salaries incurred to achieve the revenue for the year. Direct and indirect costs of raw materials and consumables, rentals, leasing and royalties are also included within this account.

## 2.9 Financial results

Financial results include interest expenses, interest income, bank charges, the amortization of financial assets and liabilities, and foreign exchange gains and losses. The Group has capitalized the borrowing cost for wells and facilities that were initiated after 1 January 2009. The capitalization rate used to determine the amount of borrowing costs to be capitalized is the weighted average interest rate applicable to the Group’s general borrowings during the year, which was 6.90% at year-end 2018 (6.90% at year-end 2017 and 7.98% in 2016). Amounts capitalized during the year amounted to US$ 257,507 (US$ 610,841 in 2017 and US$ 254,950 in 2016).

## 2.10 Property, plant and equipment

Property, plant and equipment are stated at historical cost less depreciation and impairment charges, if applicable. Historical cost includes expenditure that is directly attributable to the acquisition of the items; including provisions for asset retirement obligation.

Oil and gas exploration and production activities are accounted for in accordance with the successful efforts method on a field by field basis. The Group accounts for exploration and evaluation activities in accordance with IFRS 6, Exploration for and Evaluation of Mineral Resources, capitalizing exploration and evaluation costs until such time as the economic viability of producing the underlying resources is determined. Costs incurred prior to obtaining legal rights to explore are expensed immediately to the Consolidated Statement of Income.

Exploration and evaluation costs may include: license acquisition, geological and geophysical studies (i.e.: seismic), direct labour costs and drilling costs of exploratory wells. No depreciation and/or amortization are charged during the exploration and evaluation phase. Upon completion of the evaluation phase, the prospects are either transferred to oil and gas properties or charged to expense (exploration costs) in the period in which the determination is made, depending whether they have discovered reserves or not. If not developed, exploration and evaluation assets are written off after three years, unless it can be clearly demonstrated that the carrying value of the investment is recoverable.

A charge of US$ 26,389,000 has been recognized in the Consolidated Statement of Income within Write-off of unsuccessful exploration efforts (US$ 5,834,000 in 2017 and US$ 31,366,000 in 2016). See Note 20.

All field development costs are considered construction in progress until they are finished and capitalized within oil and gas properties, and are subject to depreciation once completed. Such costs may include the acquisition and installation of production facilities, development drilling costs (including dry holes, service wells and seismic surveys for development purposes), project-related engineering and the acquisition costs of rights and concessions related to proved properties.



Workovers of wells made to develop reserves and/or increase production are capitalized as development costs. Maintenance costs are charged to the Consolidated Statement of Income when incurred.

Capitalized costs of proved oil and gas properties and production facilities and machinery are depreciated on a licensed area by the licensed area basis, using the unit of production method, based on commercial proved and probable reserves. The calculation of the "unit of production" depreciation takes into account estimated future finding and development costs and is based on current year-end unescalated price levels. Changes in reserves and cost estimates are recognized prospectively. Reserves are converted to equivalent units on the basis of approximate relative energy content.

Depreciation of the remaining property, plant and equipment assets (i.e. furniture and vehicles) not directly associated with oil and gas activities has been calculated by means of the straight-line method by applying such annual rates as required to write-off their value at the end of their estimated useful lives. The useful lives range between 3 years and 10 years.

Depreciation is allocated in the Consolidated Statement of Income as a separate line to better follow the performance of the business.

An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount (see Impairment of non-financial assets in Note 2.12).

## 2.11 Provisions and other long-term liabilities

Provisions for asset retirement obligations, deferred income, restructuring obligations and legal claims are recognized when the Group has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated. Restructuring provisions comprise lease termination penalties and employee termination payments.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to the passage of time is recognized as financial expense.

## 2.11.1 Asset Retirement Obligation

The Group records the fair value of the liability for asset retirement obligations in the period in which the wells are drilled. When the liability is initially recorded, the Group capitalizes the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value at each reporting period, and the capitalized cost is depreciated over the estimated useful life of the related asset. According to interpretations and the application of current legislation, and on the basis of the changes in technology and the variations in the costs of restoration necessary to protect the environment, the Group has considered it appropriate to periodically re-evaluate future costs of well-capping. The effects of this recalculation are included in the financial statements in the period in which this recalculation is determined and reflected as an adjustment to the provision and the corresponding property, plant and equipment asset.

## 2.11.2 Deferred Income

Relates to contributions received in cash from the Group’s clients to improve the project economics of gas wells. The amounts collected are reflected as a deferred income in the balance sheet and recognized in the Consolidated Statement of Income over the productive life of the associated wells. The depreciation of the gas wells that generated the deferred income is charged to the Consolidated Statement of Income simultaneously with the amortization of the deferred income. The amounts used in 2017 correspond to the deferred income related to the take-or-pay provision associated to gas sales in Brazil.

## 2.12 Impairment of non-financial assets

Assets that are not subject to depreciation and/or amortization (i.e.: exploration and evaluation assets) are tested annually for impairment. Assets that are subject to depreciation and/or amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

An impairment loss is recognized for the excess of the asset’s carrying amount over its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units), generally a licensed area. Non-financial assets other than goodwill that suffered impairment are reviewed for possible reversal of the impairment at each reporting date.

No asset should be kept as an exploration and evaluation asset for a period of more than three years, except if it can be clearly demonstrated that the carrying value of the investment will be recoverable.

During 2018, impairment loss was reversed for US$ 4,982,000 (no impairment loss recognized or reversed in 2017 and impairment loss reversed for US$ 5,664,000 in 2016). See Note 36. The write-offs are detailed in Note 20.

## 2.13 Lease contracts

All current lease contracts are considered to be operating leases on the basis that the lessor retains substantially all the risks and rewards related to the ownership of the leased asset. Payments related to operating leases and other rental agreements are recognized in the Consolidated Income Statement on a straight-line basis over the term of the contract. The Group’s total commitment relating to operating leases and rental agreements is disclosed in Note 32.3.



Leases in which substantially all of the risks and rewards of ownership are transferred to the lessee are classified as finance leases. Under a finance lease, the Group as lessor has to recognize an amount receivable equal to the aggregate of the minimum lease payments plus any unguaranteed residual value accruing to the lessor, discounted at the interest rate implicit in the lease.

## 2.14 Inventories

Inventories comprise crude oil and materials.

Crude oil is measured at the lower of cost and net realizable value. Materials are measured at the lower of cost and recoverable amount. The cost of materials and consumables is calculated at acquisition price with the addition of transportation and similar costs. Cost is determined using the first-in, first-out (FIFO) method.

## 2.15 Current and deferred income tax

The tax expense for the year comprises current and deferred tax. Tax is recognized in the Consolidated Statement of Income.

The current income tax charge is calculated on the basis of the tax laws enacted or substantially enacted at the balance sheet date in the countries where the Company’s subsidiaries operate and generate taxable income. The computation of the income tax expense involves the interpretation of applicable tax laws and regulations in many jurisdictions. The resolution of tax positions taken by the Group, through negotiations with relevant tax authorities or through litigation, can take several years to complete and, in some cases, it is difficult to predict the ultimate outcome.

Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the Consolidated Financial Statements. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted as of the balance sheet date and are expected to apply when the related deferred income tax asset is realized, or the deferred income tax liability is settled.

In addition, the Group has tax-loss carry-forwards in certain tax jurisdictions that are available to be offset against future taxable profit. However, deferred tax assets are recognized only to the extent that it is probable that taxable profit will be available against which the unused tax losses can be utilized. Management judgment is exercised in assessing whether this is the case. To the extent that actual outcomes differ from management’s estimates, taxation charges or credits may arise in future periods.

Deferred income tax liabilities are provided on taxable temporary differences arising from investments in subsidiaries and joint arrangements, except for deferred income tax liability where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future. The Group is able to control the timing of dividends from its subsidiaries and hence does not expect taxable profit. Hence deferred tax is recognized in respect of the retained earnings of overseas subsidiaries only if at the date of the statements of financial position, dividends have been accrued as receivable or a binding agreement to distribute past earnings in future has been entered into by the subsidiary. As mentioned above the Group does not expect that the temporary differences will revert in the foreseeable future. In the event that these differences revert in total (e.g. dividends are declared and paid), the deferred tax liability which the Group would have to recognize amounts to approximately US$ 11,400,000.

Deferred tax balances are provided in full, with no discounting.

## 2.16 Non-current assets or disposal groups held for sale

Non-current assets or disposal groups are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use and a sale is considered highly probable. They are measured at the lower of their carrying amount and fair value less costs to sell, except for assets such as deferred tax assets, assets arising from employee benefits, financial assets and investment property that are carried at fair value and contractual rights under insurance contracts, which are specifically exempt from this requirement.

An impairment loss is recognized for any initial or subsequent write-down of the asset or disposal group to fair value less costs to sell. A gain is recognized for any subsequent increases in fair value less costs to sell of an asset or disposal group, but not in excess of any cumulative impairment loss previously recognized. A gain or loss not previously recognized by the date of the sale of the non-current asset or disposal group is recognized at the date of derecognition.

Non-current assets (including those that are part of a disposal group) are not depreciated or amortized while they are classified as held for sale. Interest and other expenses attributable to the liabilities of a disposal group classified as held for sale continue to be recognized.

Non-current assets classified as held for sale and the assets of a disposal group classified as held for sale are presented separately from the other assets in the Consolidated Statement of Financial Position. The liabilities of a disposal group classified as held for sale are presented separately from other liabilities in the Consolidated Statement of Financial Position.

## 2.17 Financial assets

Financial assets are divided into the following categories: amortized cost; financial assets at fair value through profit or loss and fair value through other comprehensive income. The classification depends on the Group’s business model for managing the financial assets and the contractual terms of the cash flows. The Group reclassifies debt investments when and only when its



business model for managing those assets changes.

All financial assets not at fair value through profit or loss are initially recognized at fair value, plus transaction costs. Transaction costs of financial assets carried at fair value through profit or loss, if any, are expensed to profit or loss.

Derecognition of financial assets occurs when the rights to receive cash flows from the investments expire or are transferred and substantially all of the risks and rewards of ownership have been transferred. An assessment for impairment is undertaken at each balance sheet date.

Interest and other cash flows resulting from holding financial assets are recognized in the Consolidated Statement of Income when receivable, regardless of how the related carrying amount of financial assets is measured.

Amortized cost are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for maturities greater than twelve months after the balance sheet date. These are classified as non-current assets. These financial assets comprise trade receivables, prepayments and other receivables and cash and cash equivalents in the Consolidated Statement of Financial Position. They arise when the Group provides money, goods or services directly to a debtor with no intention of trading the receivables. These financial assets are subsequently measured at amortized cost using the effective interest method, less provision for impairment, if applicable.

Any change in their value through impairment or reversal of impairment is recognized in the Consolidated Statement of Income. All of the Group's financial assets are classified as amortized cost.

## 2.18 Other financial assets

Non-current other financial assets include contributions made for environmental obligations according to a Colombian and Brazilian government request and are restricted for those purposes.

Current other financial assets include short-term investments with original maturities up to twelve months and over three months. As of 31 December 2017, they also included the security deposit granted in relation to the purchase of Argentinian assets (see Note 35.3).

## 2.19 Impairment of financial assets

The Group assesses on a forward-looking basis the expected credit losses associated with its debt instruments. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognized from initial recognition of the receivables.

## 2.20 Cash and cash equivalents

Cash and cash equivalents includes cash in hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts, if any, are shown within borrowings in the current liabilities section of the Consolidated Statement of Financial Position.

## 2.21 Trade and other payables

Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of the business from suppliers. Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.

## 2.22 Derivatives

Derivative financial instruments are recognized in the statement of financial position as assets or liabilities and initially and subsequently measured at fair value through profit and loss. They are presented as current assets or liabilities if they are expected to be settled within 12 months after the end of the reporting period.

The mark-to-market fair value of the Group’s outstanding derivative instruments is based on independently provided market rates and determined using standard valuation techniques, including the impact of counterparty credit risk and are within level 2 of the fair value hierarchy. Gains and losses arising from changes in fair value are recognized in the Consolidated Statement of Income within Commodity risk management contracts.

For more information about derivatives please refer to Note 8.

## 2.23 Borrowings

Borrowings are obligations to pay cash and are recognized when the Group becomes a party to the contractual provisions of the instrument.

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the Consolidated Statement of Income over the period of the borrowings using the effective interest method.

Direct issue costs are charged to the Consolidated Statement of Income on an accrual basis using the effective interest method.

## 2.24 Share capital

Equity comprises the following:

• “Share capital” representing the nominal value of equity shares.

• “Share premium” representing the excess over nominal value of the fair value



of consideration received for equity shares, net of expenses of the share issuance.

• "Other reserve" representing:

– the equity element attributable to shares granted according to IFRS 2 but not issued at year end or,

– the difference between the proceeds from the transaction with non-controlling interests received against the book value of the shares acquired in the Chilean and Colombian subsidiaries.

• “Translation reserve” representing the differences arising from translation of investments in overseas subsidiaries.

• “(Accumulated losses) Retained earnings” representing accumulated earnings and losses.

## 2.25 Share-based payment

The Group operates a number of equity-settled share-based compensation plans comprising share awards payments to certain employees and other third-party contractors. Share-based payment transactions are measured in accordance with IFRS 2.

Fair value of the stock option plan for employee or contractors services received in exchange for the grant of the options is recognized as an expense. The total amount to be expensed over the vesting period is determined by reference to the fair value of the options granted calculated using the Geometric Brownian Motion method.

Non-market vesting conditions are included in assumptions about the number of options that are expected to vest. At each balance sheet date, the entity revises its estimates of the number of options that are expected to vest. It recognizes the impact of the revision to original estimates, if any, in the Consolidated Statement of Income, with a corresponding adjustment to equity.

The fair value of the share awards payments is determined at the grant date by reference of the market value of the shares and recognized as an expense over the vesting period. When the awards are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital (nominal value) and share premium when the options are exercised.

## Note 3

## Financial Instruments-risk management

The Group is exposed through its operations to the following financial risks:

• Currency risk

• Price risk

• Credit risk – concentration

• Funding and liquidity risk

• Interest rate risk

• Capital risk management

The policy for managing these risks is set by the Board of Directors. Certain risks are managed centrally, while others are managed locally following guidelines communicated from the corporate department. The policy for each of the above risks is described in more detail below.

## Currency risk

In Colombia, Chile, Argentina and Peru the functional currency is the US Dollar. The fluctuation of the local currencies of these countries against the US Dollar does not impact the loans, costs and revenue held in US Dollars; but it does impact the balances denominated in local currencies. Such is the case of the prepaid taxes.

In Colombian, Chilean, Argentinean and Peruvian subsidiaries most of the balances are denominated in US Dollars, and since it is the functional currency of the subsidiaries, there is no exposure to currency fluctuation except from receivables or payables originated in local currency mainly corresponding to VAT and income tax.

The Group minimises the local currency positions in Colombia, Chile, Argentina and Peru by seeking to balance local and foreign currency assets and liabilities. However, tax receivables (VAT) seldom match with local currency liabilities. Therefore, the Group maintains a net exposure to them, except for what it is described below.

In December 2018, GeoPark decided to manage its future exposure to local currency fluctuation with respect to income tax balances in Colombia. Consequently, the Group entered into a derivative financial instrument with a local bank in Colombia, for an amount equivalent to US$ 92,050,000, in order to anticipate any currency fluctuation with respect to income taxes to be paid during the first half of 2019. The Group's derivatives are accounted for as non-hedge derivatives as of 31 December 2018 and therefore all changes in the fair values of its derivative contracts are recognized as gains or losses in the results of the periods in which they occur. Considering that the instrument was subscribed by year-end, as of 31 December 2018 the impact was not material.

Most of the Group’s assets held in those countries are associated with oil and gas productive assets. Those assets, even in the local markets, are generally settled in US Dollar equivalents.

During 2018, the Colombian Peso devalued by 9% (revalued by 1% in 2017 and 5% in 2016) against the US Dollar, the Chilean Peso devalued by 13% (revalued by 8% in 2017 and devalued by 6% in 2016), the Argentine Peso devalued by 102% (17% and 22% in 2017 and 2016) and the Peruvian Peso devalued by 4% (revalued by 4% in 2017 and 2% in 2016).

If the Colombian Peso, the Chilean Peso, the Argentine Peso and the Peruvian Peso had each devalued an additional 10% against the US dollar, with all other variables held constant, post-tax profit for the year would have been lower by US$ 57,000 (post-tax loss higher by US$ 1,538,000 in 2017 and US$ 2,683,400 in 2016).



In Brazil, the functional currency is the local currency, which is the Brazilian Real. The fluctuation of the US Dollars against the Brazilian Real does not impact the loans, costs and revenues held in Brazilian Real; but it does impact the balances denominated in US Dollars. Such is the case of the provision for asset retirement obligation and the intercompany loan, which was fully cancelled in October 2018, reducing significantly the exposure to foreign currency fluctuation. The exchange loss generated by the Brazilian subsidiary during 2018 amounted to US$ 5,862,000 (loss of US$ 1,274,000 in 2017 and gain of US$ 14,542,000 in 2016).

During 2018, the Brazilian Real devalued by 17% against the US Dollar (devalued by 2% in 2017 and revalued by 17% in 2016, respectively). If the Brazilian Real had devalued 10% against the US dollar, with all other variables held constant, post-tax profit for the year would have been lower by US$ 515,000 (post-tax loss higher by US$ 3,100,000 in 2017 and US$ 5,300,000 in 2016).

As currency rate changes between the US Dollar and the local currencies, the Group recognizes gains and losses in the Consolidated Statement of Income.

## Price risk

The realized oil price for the Group is linked to US dollar denominated crude oil international benchmarks. The market price of this commodity is subject to significant volatility and has historically fluctuated widely in response to relatively minor changes in the global supply and demand for oil, the geopolitical landscape, the economic conditions and a variety of additional factors. The main factors affecting realized prices for gas sales vary across countries with some closely linked to international references while others are more domestically driven.

In Colombia, the realized oil price is linked to the Vasconia crude reference price, a marker broadly used in the Llanos basin, adjusted for certain marketing and quality discounts based on, among other things, API, viscosity, sulphur content, water content, delivery point and transport costs.

In Chile, the oil price is based on Dated Brent minus certain marketing and quality discounts such as, API, sulphur content and others.

GeoPark has signed a long-term Gas Supply Contract with Methanex in Chile. The price of the gas sold under this contract is determined by a formula that considers a basket of international methanol prices, including US Gulf methanol spot barge prices, methanol spot Rotterdam prices and spot prices in Asia.

In Brazil, prices for gas produced in the Manati Field are based on a long-term off-take contract with Petrobras. The price of gas sold under this contract is denominated in Brazilian Real and is adjusted annually for inflation pursuant to the Brazilian General Market Price Index (Indice Geral de Preços do Mercado), or IGPM.
In Argentina, the realized oil prices for our production in the Neuquen Basin follows the “Medanito” blend oil price reference, which has traditionally been linked to ICE Brent adjusted by certain marketing and quality discounts based on API, delivery point and transport costs. Between May and November 2018, Medanito crude prices were capped industry-wide between US$ 65 per barrel and US$ 70 per barrel. Since December 2018, domestic prices have reconnected to the international benchmark.

Gas sales in Argentina are carried out through annual contracts that go from May to April. The price of the gas sold under these contracts depends mainly on domestic supply and demand and regulation affecting the sector.

If oil and methanol prices had fallen by 10% compared to actual prices during the year, with all other variables held constant, considering the impact of the derivative contracts in place, post-tax profit for the year would have been lower by US$ 13,709,000 (post-tax loss higher by US$ 10,423,000 in 2017 and US$ 23,655,000 in 2016).

Since October 2016, GeoPark decided to manage part of the exposure to crude oil price volatility using derivatives. The Group considers these derivative contracts to be an effective manner of properly managing commodity price risk. The price risk management activities mainly employ combinations of options and key parameters are based on forecasted production and budget price levels. GeoPark has also obtained credit lines from industry leading counterparties to minimize the potential cash exposure of the derivative contracts (see Note 8).

## Credit risk – concentration

The Group’s credit risk relates mainly to accounts receivable where the credit risks correspond to the recognized values of commodities sold. GeoPark considers that there is no significant risk associated to the Group’s major customers and hedging counterparties.

In Colombia, during 2018, the Colombian subsidiary made 99% of the oil sales to Trafigura (one of the world's leading independent commodity trading and logistics houses), with Trafigura accounting for 82% of the consolidated revenue for the same period. With the expiration of our long-term contract with Trafigura in December 2018, GeoPark began diversifying its client base in Colombia, allocating sales on a competitive basis to industry leading participants including traders and other producers. The contracts extend through 2019 with no longer term delivery commitments in place. Delivery points include wellhead and other locations on the Colombian pipeline system. GeoPark manages its counterparty credit risk associated to sales contracts by including early payment conditions to minimize the exposure.

All the oil produced in Chile as well as the gas produced by TdF blocks (3%



of the consolidated revenue, 5% in 2017 and 10% in 2016) is sold to ENAP, the State-owned oil and gas company. In Chile, most of gas production is sold to the local subsidiary of Methanex, a Canadian public company (3% of the consolidated revenue, 5% in 2017 and 9% in 2016).

In Brazil, all the hydrocarbons from Manati Field are sold to Petrobras, the State-owned company, which is the operator of the Manati Field (5% of the consolidated revenue, 10% in 2017 and 15% in 2016).

In Argentina, all the gas produced is sold to Grupo Albanesi, a leading Argentine privately-held conglomerate focused on the energy market that offers natural gas, power supply and transport services to its customers. GeoPark has an annual agreement in effect from May 2018 through April 2019. Gas sales in Argentina account for 1% of the consolidated revenues.

The oil sales in Argentina are diversified across clients and delivery points: i) 30% of the oil produced in Argentina (2% of the consolidated revenue) is sold locally in Neuquen, delivered at well-head; and ii) 70% of the oil produced in Argentina (3% of the consolidated revenue) is sold to major Argentinean refineries, delivered via pipeline. GeoPark manages the counterparty credit risk associated to sales contracts by limiting payment terms offered to minimize the exposure.

The forementioned companies all have a good credit standing and despite the concentration of the credit risk, the Directors do not consider there to be a significant collection risk.

Since October 2016, the Group has executed oil prices hedges via over-the-counter derivatives. Should oil prices drop, the Group could stand to collect from its counterparties under the derivative contracts. The Group’s hedging counterparties are leading financial institutions and trading companies, therefore the Directors do not consider there to be a significant collection risk.

See disclosure in Notes 8 and 25.

## Funding and Liquidity risk

In the past, the Group was able to raise capital through different sources of funding including equity, strategic partnerships and financial debt. During 2017, the Group placed US$ 425,000,000 Notes (see Note 27).

The Group is positioned at the end of 2018 with a cash balance of US$ 127,727,000 and over 95% of its total indebtedness matures in 2024. In addition, the Group has a large portfolio of attractive and largely discretionary projects - both oil and gas - in multiple countries with over 39,000 boepd in production at year end. This scale and positioning permit the Group to protect its financial condition and selectively allocate capital to the optimal projects subject to prevailing macroeconomic conditions.

The Indenture governing the Company Notes 2024 includes incurrence test covenants related to compliance with certain thresholds of Net Debt to Adjusted EBITDA ratio and Adjusted EBITDA to Interest ratio. Failure to comply with the incurrence test covenants does not trigger an event of default. However, this situation may limit the Group’s capacity to incur additional indebtedness, as specified in the indenture governing the Notes. As of the date of these Consolidated Financial Statements, the Group is in compliance with all the indenture’s provisions and covenants.

The most significant funding transactions executed during 2018 and 2017 include:

In October 2018, the Brazilian subsidiary executed a loan agreement with Banco Santander for Brazilian Real 77,640,000 (equivalent to US$ 20,000,000 at the moment of the loan execution) to repay an existing US\)-denominated intercompany loan to GeoPark Latin America Limited - Agencia en Chile. The interest rate applicable to this loan is CDI plus 2.25% per annum. "CDI" (Interbank certificate of deposit) represents the average rate of all inter-bank overnight transactions in Brazil. The principal and the interest are paid semi-annually, with final maturity in October 2020.

In April 2018, the Colombian subsidiary executed an offtake and prepayment agreement with Trafigura, one of its customers. The prepayment agreement provided GeoPark with access to up to US$ 25,000,000 in the form of prepaid future oil sales. The availability period for the prepayment agreement expires on 31 March 2019. As of the date of these Consolidated Financial Statements, GeoPark has not withdrawn any amount from this prepayment agreement.

In September 2017, the Company successfully placed US$ 425,000,000 Notes. These Notes carry a coupon of 6.50% per annum and their final maturity will be 21 September 2024. The net proceeds from the Notes were used by the Group to fully repay the 7.50% senior secured Notes due 2020 and for general corporate purposes, including capital expenditures and to repay other existing indebtedness.

## Interest rate risk

The Group’s interest rate risk arises from long-term borrowings issued at variable rates, which expose the Group to interest rate risk.

The Group does not face interest rate risk on its US$ 425,000,000 Notes which carry a fixed rate coupon of 6.50% per annum. Consequently, the accruals and interest payment are not substantially affected by the market interest rate changes.

At 31 December 2018, the outstanding long-term borrowing affected by a variable rate amounted to US$ 19,750,000, representing 4.5% of total borrowings. It corresponds to a loan from Santander Bank taken by the Brazilian subsidiary that has a floating interest rate based on CDI (Interbank certificate of deposit), which represents the average rate of all inter-bank overnight transactions in Brazil.



The Group analyses its interest rate exposure on a dynamic basis. Various scenarios are simulated taking into consideration refinancing, renewal of existing positions, alternative financing and hedging. Based on these scenarios, the Group calculates the impact on profit and loss of a defined interest rate. For each simulation, the same interest rate is used for all currencies. The scenarios are run only for liabilities that represent the major interest-bearing positions.

At 31 December 2018, if 1% is added to interest rates on currency-denominated borrowings with all other variables held constant, post-tax profit for the year would have been lower by US$ 21,000 (no exposure to fluctuations in the interest rate in 2017 and post-tax loss higher by US$ 467,000 in 2016).

## Capital risk management

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

Consistent with others in the industry, the Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings (including 'current and non-current borrowings' as shown in the consolidated balance sheet) less cash and cash equivalents. Total capital is calculated as 'equity' as shown in the consolidated balance sheet plus net debt.

The Group’s strategy, due to the market conditions prevailing during the last years and the growth strategy of the Group, is to keep the gearing ratio within a 60% to 80% range.

The gearing ratios at 31 December 2018 and 2017 were as follows:

<table><tr><td>Amounts in US$ &#x27;000</td><td>2018</td><td>2017</td></tr><tr><td>Net Debt</td><td>319,275</td><td>291,449</td></tr><tr><td>Total Equity</td><td>143,021</td><td>126,840</td></tr><tr><td>Total Capital</td><td>462,296</td><td>418,289</td></tr><tr><td>Gearing Ratio</td><td>69%</td><td>70%</td></tr></table>

## Note 4

## Accounting estimates and assumptions

Estimates and assumptions are used in preparing the financial statements. Although these estimates are based on management’s best knowledge of current events and actions, actual results may differ. Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The key estimates and assumptions used in these Consolidated Financial Statements are noted below:

• Cash flow estimates for impairment assessments of non-financial assets require assumptions about two primary elements: future prices and reserves. Estimates of future prices require significant judgments about highly uncertain future events. Historically, oil and gas prices have exhibited significant volatility. The Group’s forecasts for oil and gas revenues are based on prices derived from future price forecasts amongst industry analysts and internal assessments. Estimates of future cash flows are generally based on assumptions of long-term prices and operating and development costs.

Given the significant assumptions required and the possibility that actual conditions may differ, management considers the assessment of impairment to be a critical accounting estimate (see Note 36).

The process of estimating reserves is complex. It requires significant judgements and decisions based on available geological, geophysical, engineering and economic data. The estimation of economically recoverable oil and natural gas reserves and related future net cash flows was performed based on the Reserve Report as of 31 December 2018 prepared by DeGolyer and MacNaughton, an independent international consultancy to the oil and gas industry based in Dallas. It incorporates many factors and assumptions including:

– expected reservoir characteristics based on geological, geophysical and engineering assessments;

– future production rates based on historical performance and expected future operating and investment activities;

– future oil and gas prices and quality differentials;

– assumed effects of regulation by governmental agencies; and

– future development and operating costs.

Management believes these factors and assumptions are reasonable based on the information available to them at the time of preparing the estimates. However, these estimates may change substantially as additional data from ongoing development activities and production performance becomes available and as economic conditions impacting oil and gas prices and costs change.

• The Group adopts the successful efforts method of accounting. The Management of the Group makes assessments and estimates regarding whether an exploration and evaluation asset should continue to be carried forward as such when insufficient information exists. This assessment is made on a quarterly basis considering the advice from qualified experts.

• Oil and gas assets held in property plant and equipment are mainly depreciated on a unit of production basis at a rate calculated by reference to proven and probable reserves and incorporating the estimated future cost of developing and extracting those reserves. Future development costs are



estimated using assumptions as to the numbers of wells required to produce those reserves, the cost of the wells and future production facilities.

• Obligations related to the abandonment of wells once operations are terminated may result in the recognition of significant obligations. Estimating the future abandonment costs is difficult and requires management to make estimates and judgments because most of the obligations are many years in the future. Technologies and costs are constantly changing as well as political, environmental, safety and public relations considerations. The Group has adopted the following criterion for recognizing well plugging and abandonment related costs: The present value of future costs necessary for well plugging and abandonment is calculated for each area at the present value of the estimated future expenditure. The liabilities recognized are based upon estimated future abandonment costs, wells subject to abandonment, time to abandonment, and future inflation rates.

• From time to time, the Group may be subject to various lawsuits, claims and proceedings that arise in the normal course of business, including employment, commercial, tax, environmental, safety and health matters. For example, from time to time, the Group receives notice of environmental, health and safety violations. Based on what the Management of the Group currently knows, it is not expected any material impact on the financial statements.

## Note 5

## Consolidated Statement of Cash Flow

The Consolidated Statement of Cash Flow shows the Group’s cash flows for the year for operating, investing and financing activities and the change in cash and cash equivalents during the year.

Cash flows from operating activities are computed from the results for the year adjusted for non-cash operating items, changes in net working capital, and corporate tax. Income tax paid is presented as a separate item under operating activities.

Cash flows from investing activities include payments in connection with the purchase and sale of property, plant and equipment and cash flows relating to the purchase and sale of enterprises to third parties, if any.

Cash flows from financing activities include changes in equity, and proceeds from borrowings and repayment of loans.

## Segment information

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Executive Committee. This committee is integrated by the CEO, COO, CFO and managers in charge of the Geoscience, Operations, Corporate Governance, Finance and People departments. This committee reviews the Group's internal reporting in order to assess performance and to allocate resources. Management has determined the operating segments based on these reports. The committee considers the business from a geographic perspective.

The Executive Committee assesses the performance of the operating segments based on a measure of Adjusted EBITDA. Adjusted EBITDA is defined as profit for the period before net finance cost, income tax, depreciation, amortization, certain non-cash items such as impairments and write-offs of unsuccessful efforts, accrual of share-based payment, unrealized result on commodity risk management contracts and other non-recurring events. Operating Netback is equivalent to Adjusted EBITDA before cash expenses included in Administrative, Geological and Geophysical and Other operating expenses. Other information provided, except as noted below, to the Executive Committee is measured in a manner consistent with that in the financial statements.

## Commodity risk management contracts

The Group has entered into derivative financial instruments to manage its exposure to oil price risk. These derivatives are zero-premium collars or zero-premium 3 ways (put spread plus call), and were placed with major financial institutions and commodity traders. The Group entered into the derivatives under ISDA Master Agreements and Credit Support Annexes, which provide credit lines for collateral posting thus alleviating possible liquidity needs under the instruments and protect the Group from potential non-performance risk by its counterparties. The Group’s derivatives are accounted for as non-hedge derivatives as of 31 December 2018 and therefore all changes in the fair values of its derivative contracts are recognised as gains or losses in the results of the periods in which they occur.



The following table presents the Group’s derivative contracts in force as of 31 December 2018:

<table><tr><td>Period</td><td>Reference</td><td>Type</td><td>Volume bbl/d</td><td>Price US$/bbl</td></tr><tr><td>1 April 2018 - 31 December 2018</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>3,000</td><td>45.00-55.00 Put 77.15 Call</td></tr><tr><td>1 April 2018 - 31 December 2018</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>1,000</td><td>45.00-55.00 Put 77.50 Call</td></tr><tr><td>1 July 2018 - 31 March 2019</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>2,000</td><td>50.00-60.00 Put 97.00 Call</td></tr><tr><td>1 July 2018 - 31 March 2019</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>2,000</td><td>50.00-60.00 Put 97.05 Call</td></tr><tr><td>1 October 2018 - 30 June 2019</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>3,700</td><td>55.00-65.00 Put 90.00 Call</td></tr><tr><td>1 October 2018 - 30 June 2019</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>1,000</td><td>55.00-65.00 Put 90.10 Call</td></tr><tr><td>1 October 2018 - 30 June 2019</td><td>ICE BRENT</td><td>Zero Premium 3 Way</td><td>1,300</td><td>55.00-65.00 Put 90.50 Call</td></tr><tr><td>1 January 2019 - 30 September 2019</td><td>ICE BRENT</td><td>Zero Premium Collar</td><td>2,000</td><td>65.00 Put 92.50 Call</td></tr><tr><td>1 January 2019 - 30 September 2019</td><td>ICE BRENT</td><td>Zero Premium Collar</td><td>3,000</td><td>65.00 Put 92.26 Call</td></tr></table>

## Tax reforms

## Colombia

In December 2018, a tax reform was enacted in Colombia. The approved legislation included significant changes in the corporate income tax but also in other taxes and in tax related matters (as procedural rules and special regimes). This tax reform was effective 1 January 2019.

The new legislation includes a progressive reduction of the general corporate income tax rate, previously established at 40% for 2017 and 37% for 2018, as follows:

• 33% in 2019

• 32% in 2020

• 31% in 2021

• 30% in 2022 and onwards.

Other changes that could affect the Group are the following:

• The withholding tax rate on dividends for non-resident shareholders was increased from 5% to 7.5%.

• The withholding tax rates applicable on payments to non-residents on behalf of consultancy, technical services, technical assistance, software and interests on loans of less than one year were increased from 15% to 20% (for loans with maturity exceeding one year, the 15% rate remained unchanged).

• The withholding tax rate applicable on payments to entities resident of countries considered to be tax havens, non-cooperative or to grant a



preferential tax regime was increased from 15% to the corporate income tax rate (33% for 2019, 32% for 2020, 31% for 2021 and 30% for 2022 and onwards).

• The deduction of interest attributed to a permanent establishment in Colombia on behalf of its head office debt was limited to interest that had been subject to Colombian withholding tax.

• Regarding thin capitalization for income tax purposes, the maximum amount of debt which interest can be deducted was reduced from 3 to 2 times the net equity of the taxpayer as of 31 December of the previous year.
• Transfers of participations in foreign entities that represent indirect disposals of assets in Colombia became subject to income tax or to the occasional earnings tax, depending on certain circumstances.

• VAT paid for acquisition of productive fixed assets could be credited against corporate income tax.

• An audit benefit was granted by the reform, establishing that tax returns of FY 2019 and 2020 showing a net income tax 30% or 20% higher, respectively, than the one declared in the previous year would be considered definitive 6 months or 12 months after became due, also respectively, if there were no objections or requests from the tax authority.

## Argentina

A tax reform has been enacted in Argentina during December 2017. The legislation included significant changes to certain corporate income tax and statutory income tax provisions, including rate reductions. Most of the tax provisions are effective from fiscal year 2018.

With this tax reform, the corporate income tax -previously 35%- will have the following rate schedule:

• 30% in 2018 and 2019

• 25% in 2020 and 2021 and onwards.

Other changes include the following:

• New withholding tax on dividends—with the applicable rates for non-resident shareholders of: (1) 7% for dividends distributed out of the distributing entity’s previously taxed profits of fiscal years 2018 and 2019; and (2) 13% for dividends distributed out of the distributing entity’s previously taxed profits of fiscal years 2020 and onwards.

• Application of inflation adjustment for corporate tax purposes is reinstated under certain circumstances.

• Possible tax revaluation of investment in fixed assets, under payment of a special tax.

• Allow for short term recovery of VAT paid on acquisitions or imports of capital goods, when non recoverable with VAT on usual sales.

Under current Bermuda law, the Company is not required to pay any taxes in Bermuda on income or capital gains. The Company has received an undertaking from the Minister of Finance in Bermuda that, in the event of any taxes being imposed, they will be exempt from taxation in Bermuda until March 2035. Income tax rates in those countries where the Group operates (Colombia, Chile, Brazil, Argentina and Peru) ranges from 15% to 37%.

## Corporate structure reorganization

During 2017, the Company decided to incorporate a subsidiary in the United Kingdom (international investor centre) to actively conduct the strategic business and financial decisions of the Group. Also, to enhance protection to the Group's investments in Latin America and because of a predicted change of the Dutch dividend withholding tax act that would unjustifiably affect the Group's operating cash flow, GeoPark decided to re-domiciliate the Group's sub-holdings from the Netherlands to Spain (jurisdiction with a broad network of Investment Promotion and Protection Agreements with Latin American countries).

Trade receivables that are aged by less than three months are not considered impaired. As of 31 December 2018 and 2017, there are no balances that were aged by more than 3 months, but not impaired. These relate to customers for whom there is no recent history of default. There are no balances overdue between 31 days and 90 days as of 31 December 2018 and 2017.

Movements on the Group provision for impairment are as follows:

<table><tr><td>Amounts in US\( &#x27;000</td><td>2018</td><td>2017</td></tr><tr><td>At 1 January</td><td>594</td><td>741</td></tr><tr><td>Foreign exchange income</td><td>(48)</td><td>(147)</td></tr><tr><td></td><td>546</td><td>594</td></tr></table>

The credit period for trade receivables is 30 days. The maximum exposure to credit risk at the reporting date is the carrying value of each class of receivable. The Group does not hold any collateral as security related to trade receivables.

The carrying value of trade receivables is considered to represent a reasonable approximation of its fair value due to their short-term nature.

## 25.3 Fair value measurement of financial instruments

Accounting policies for financial instruments have been applied to classify as either: loans and receivables, held-to-maturity, available-for-sale, or fair value through profit and loss. For financial instruments that are measured in the statement of financial position at fair value, IFRS 13 requires a disclosure of fair value measurements by level according to the following fair value measurement hierarchy:

• Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices).

• Level 3 - Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

This note provides an update on the judgements and estimates made by the Group in determining the fair values of the financial instruments since the last annual financial report.

## 25.3.1 Fair value hierarchy

The following table presents the Group’s financial assets and financial liabilities measured and recognized at fair value at 31 December 2018 and 2017 on a recurring basis:

<table><tr><td>Amounts in US\( &#x27;000</td><td></td><td></td><td>At 31 December 2018</td></tr><tr><td></td><td>Level 1</td><td>Level 2</td><td></td></tr><tr><td>Assets</td><td></td><td></td><td></td></tr><tr><td>Cash and cash equivalents</td><td></td><td></td><td></td></tr><tr><td>Money market funds</td><td>53,794</td><td>-</td><td>53,794</td></tr><tr><td>Derivative financial instrument liabilities</td><td></td><td></td><td></td></tr><tr><td>Commodity risk management contracts</td><td>-</td><td>27,539</td><td>27,539</td></tr><tr><td>Total Liabilities</td><td>53,794</td><td>27,539</td><td>81,333</td></tr></table>



<table><tr><td>Amounts in US$ &#x27;000</td><td>Level 1</td><td>Level 2</td><td>At 31 December 2017</td></tr><tr><td>Assets</td><td></td><td></td><td></td></tr><tr><td>Cash and cash equivalents</td><td></td><td></td><td></td></tr><tr><td>Money market funds</td><td>44,123</td><td>-</td><td>44,123</td></tr><tr><td>Total Assets</td><td>44,123</td><td>-</td><td>44,123</td></tr><tr><td>Liabilities</td><td></td><td></td><td></td></tr><tr><td>Derivative financial instrument liabilities</td><td></td><td></td><td></td></tr><tr><td>Commodity risk management contracts</td><td>-</td><td>19,289</td><td>19,289</td></tr><tr><td>Total Liabilities</td><td>-</td><td>19,289</td><td>19,289</td></tr></table>

There were no transfers between Level 2 and 3 during the period.

The Group did not measure any financial assets or financial liabilities at fair value on a non-recurring basis as at 31 December 2018.

## 25.3.2 Valuation techniques used to determine fair values

Specific valuation techniques used to value financial instruments include:

• The use of quoted market prices or dealer quotes for similar instruments.
• The mark-to-market fair value of the Group’s outstanding derivative instruments is based on independently provided market rates and determined using standard valuation techniques, including the impact of counterparty credit risk and are within level 2 of the fair value hierarchy.
• The fair value of the remaining financial instruments is determined using discounted cash flow analysis. All of the resulting fair value estimates are included in level 2.

## 25.3.3 Fair values of other financial instruments (unrecognised)

The Group also has a number of financial instruments which are not measured at fair value in the balance sheet. For the majority of these instruments, the fair values are not materially different to their carrying amounts, since the interest receivable/payable is either close to current market rates or the instruments are short-term in nature.

Borrowings are comprised primarily of fixed rate debt and variable rate debt with a short-term portion where interest has already been fixed. They are classified under other financial liabilities and measured at their amortized cost.

The fair value of these financial instruments at 31 December 2018 amounts to US$ 445,582,000 (US$ 425,118,000 in 2017). The fair values are based on cash flows discounted using a rate based on the borrowing rate of 6.94% (6.90% in 2017) and are within level 2 of the fair value hierarchy.

(a) During September 2017, the Company successfully placed US$ 425,000,000 Notes which were offered to qualified institutional buyers in accordance with Rule 144A under the United States Securities Act, and outside the United States to non-U.S. persons in accordance with Regulation S under the United States Securities Act.
The Notes carry a coupon of 6.50% per annum. Final maturity of the Notes will be 21 September 2024. The Notes are secured with a guarantee granted by GeoPark Colombia Coöperatie U.A. and GeoPark Chile S.A.. The debt issuance cost for this transaction amounted to US$ 6,683,000 (debt issuance effective rate: 6.90%). The indenture governing the Notes due 2024 includes incurrence test covenants that provides among other things, that, during the first two years from the issuance date, the Net Debt to Adjusted EBITDA ratio should not exceed 3.5 times and the Adjusted EBITDA to Interest ratio should exceed 2 times. Failure to comply with the incurrence test covenants does not trigger an event of default. However, this situation may limit the Company's capacity to incur additional indebtedness, as specified in the indenture governing the Notes. Incurrence covenants as opposed to maintenance covenants must be tested by the Company before incurring additional debt or performing certain corporate actions including but not limited to dividend payments, restricted payments and others. As of the date of these Consolidated Financial Statements, the Company is in compliance of all the indenture's provisions and covenants.

(b) During February 2016, GeoPark Fell S.p.A. executed a loan agreement with Banco de Crédito e Inversiones for US$ 186,000 to finance the acquisition of vehicles for the Chilean operation. The interest rate applicable to this loan is 4.14% per annum. The interest and the principal are paid on a monthly basis, with the final maturity in February 2019.

(c) During October 2018, GeoPark Brazil Exploração y Produção de Petróleo e Gás Ltda. executed a loan agreement with Banco Santander for Brazilian Real 77,640,000 (equivalent to US$ 20,000,000 at the moment of the loan execution) to repay an existing US\)-denominated intercompany loan to GeoPark Latin America Limited - Agencia en Chile. The interest rate applicable to this loan is CDI plus 2.25% per annum. "(CDI)" (Interbank certificate of deposit) represents the average rate of all inter-bank overnight transactions in Brazil. The principal and the interest are paid semi-annually, with final maturity in October 2020. Resulting from this transaction, the Brazilian subsidiary has significantly reduced its exposure to foreign currency fluctuation, considering that its functional currency is the Brazilian Real (see Note 3).

As of the date of these Consolidated Financial Statements, the Group has available credit lines for over US$ 80,000,000.

The provision for asset retirement obligation relates to the estimation of future disbursements related to the abandonment and decommissioning of oil and gas wells (see Note 4).

Deferred income relates to contributions received to improve the project economics of the gas wells in Chile. The amortization is in line with the related asset. The amount used in 2017 corresponds to the deferred income related to the take-or-pay provision associated to gas sales in Brazil.

## Note 30

## Share-based payment

The Group has established different stock awards programs and other share-based payment plans to incentivize the Directors, senior management and employees, enabling them to benefit from the increased market capitalization of the Company.

During 2018, GeoPark announced the 2018 Equity Incentive Plan (the "Plan") to motivate and reward those employees, directors, consultants and advisors of the Group to perform at the highest level and to further the best interests of the Company and its shareholders. This Plan is designed as a master plan, with a 10-year term, and embraces all equity incentive programs that the Company decides to implement throughout such term. The maximum number of Shares available for issuance under the Plan is 5,000,000 Shares.



During 2018, the Group approved a share-based compensation program for approximately 200,000 shares. Main characteristics of the Stock Awards Programs are:

• Employees hired since July 2016 are eligible.

• Exercise price is equal to the nominal value of shares.

• Vesting date is 30 June 2019.

• Each employee could receive up to three salaries (to be pro-rated between the hiring date and the vesting date divided by 3 years) by achieving the following conditions: continue to be an employee, the stock market price at the date of vesting should be higher than the share price at the date of grant and obtain the Group minimum production, adjusted EBITDA and reserves target for the year of vesting.

During 2016, the Group approved a share-based compensation program for 1,619,105 shares. Main characteristics of the Stock Awards Programs are:

• All employees are eligible.

• Exercise price is equal to the nominal value of shares.

• Vesting date is 30 June 2019.

• Each employee could receive up to three salaries by achieving the following conditions: continue to be an employee, the stock market price at the date of vesting should be above US$ 3 and obtain the Group minimum production, adjusted EBITDA and reserves target for the year of vesting.
Also during 2016, the Group approved a plan named Value Creation Plan ("VCP") oriented to Top Management. VCP was subject to certain market conditions, among others, reaching a stock market price for the Company shares of US$ 4.05 at vesting date. VCP has been classified as an equity-settled plan. On 2 January 2019, 50% of the shares, representing 1,488,391 shares, were issued since the plan vested. The remaining 50% will be issued in January 2020, as set up in the plan.

Details of these costs and the characteristics of the different stock awards programs and other share-based payments are described in the following table and explanations:

Capital commitments are disclosed in Note 32.2.

## Note 32

## Commitments

## 32.1 Royalty commitments

In Colombia, royalties on production are payable to the Colombian Government and are determined on a field-by-field basis using a level of production sliding scale at a rate which ranges between 6%-8%. The Colombian National Hydrocarbons Agency (“ANH”) also has an additional economic right equivalent to 1% of production, net of royalties.

Under Law 756 of 2002, as modified by Law 1530 of 2012, the royalties on Colombian production of light and medium oil are calculated on a field-by-field basis, using the following sliding scale:

<table><tr><td>Average daily production in barrels</td><td>Production Royalty rate</td></tr><tr><td>Up to 5,000</td><td>8%</td></tr><tr><td>5,000 to 125,000</td><td>8% + (production - 5,000) * 0.1</td></tr><tr><td>125,000 to 400,000</td><td>20%</td></tr><tr><td>400,000 to 600,000</td><td>20% + (production - 400,000) * 0.025</td></tr><tr><td>Greater than 600,000</td><td>25%</td></tr></table>

When the API is lower than 15°, the payment is reduced to the 75% of the total calculation.

In accordance with Llanos 34 Block operation contract, when the accumulated production of each field, including the royalties' volume, exceeds 5,000,000 of barrels and the WTI exceeds the base price settled in table A, the Group should deliver to ANH a share of the production net of royalties in accordance with the following formula:  \( Q = ((P - Po) / P) \times S \) ; where Q = Economic right to be delivered to ANH, P = WTI, Po = Base price (see table A) and S = Share (see table B).

<table><tr><td></td><td></td><td>Table A</td><td>Table B</td></tr><tr><td>°API</td><td>Po (US$/barrel)</td><td>WTI (P)</td><td>S</td></tr><tr><td>&gt;29°</td><td>30.22</td><td>Po &lt; P &lt; 2Po</td><td>30%</td></tr><tr><td>&gt;22°&lt;29°</td><td>31.39</td><td>2Po &lt; P &lt; 3Po</td><td>35%</td></tr><tr><td>&gt;15°&lt;22°</td><td>32.56</td><td>3Po &lt; P &lt; 4Po</td><td>40%</td></tr><tr><td>&gt;10°&lt;15°</td><td>46.50</td><td>4Po &lt; P &lt; 5Po</td><td>45%</td></tr><tr><td></td><td></td><td>5Po &lt; P</td><td>50%</td></tr></table>

Additionally, under the terms of the Winchester Stock Purchase Agreement, GeoPark is obligated to make certain payments to the previous owners of Winchester based on the production and sale of hydrocarbons discovered by exploration wells drilled after 25 October 2011. These payments involve an overriding royalty equal to an estimated 4% carried interest on the part of the vendor. As at the balance sheet date and based on preliminary internal estimates of additions of 2P reserves since acquisition, the Group's best estimate of the total commitment over the remaining life of the concession is in a range between US$ 150,000,000 and US$ 160,000,000. During 2018, the Group has accrued US$ 20,551,000 (US$ 11,369,000 in 2017 and US$ 5,414,000 in 2016) and paid US$ 19,128,000 (US$ 9,981,000 in 2017 and US$ 3,772,000 in 2016).

In Chile, royalties are payable to the Chilean Government. In the Fell Block, royalties are calculated at 5% of crude oil production and 3% of gas production. In the Flamenco Block, Campanario Block and Isla Norte Block, royalties are calculated at 5% of gas and oil production.

In Brazil, the Brazilian National Petroleum, Natural Gas and Biofuels Agency (ANP) is responsible for determining monthly minimum prices for petroleum



produced in concessions for purposes of royalties payable with respect to production. Royalties generally correspond to a percentage ranging between 5% and 10% applied to reference prices for oil or natural gas, as established in the relevant bidding guidelines (edital de licitação) and concession agreement. In determining the percentage of royalties applicable to a concession, the ANP takes into consideration, among other factors, the geological risks involved and the production levels expected. In the Manati Block, royalties are calculated at 7.5% of gas production.

In Argentina, crude oil and gas production accrues royalties payable to the Provinces of Mendoza and Neuquen equivalent to 15% on estimated value at well head of those products. This value is equivalent to final sales price less transport, storage and treatment costs.

## 32.2 Capital commitments

## 32.2.1 Colombia

The VIM 3 Block minimum investment program consists of 200 km of 2D seismic and drilling one exploratory well, with a total estimated investment of US$ 22,290,800 during the initial three-year exploratory period ending 2 September 2018. On 12 September 2018, the Colombian National Hydrocarbons Agency (“ANH”) accepted GeoPark’s proposal to extend the first exploratory phase for an additional period ending 12 May 2019. Additionally, GeoPark requested ANH to terminate the E&P Contract due to environmental restrictions in the block. These restrictions became apparent once the National Authority of Environmental Licenses (ANLA) issued the environmental license. As of the date of these consolidated financial statements, GeoPark’s termination request is under review.

The Llanos 34 Block (45% working interest) has committed to drill an exploratory well, which amounts to US$ 1,935,000 at GeoPark's working interest, before 19 September 2019.

## 32.2.2 Chile

The remaining investment commitment for the second exploratory phase in the Flamenco Block relates to the drilling of one exploratory well to be assumed 100% by GeoPark and amounts to US$ 2,100,000. On 30 June 2017, the Chilean Ministry accepted GeoPark's proposal to extend the second exploratory phase for an additional period of 18 months, ending on 7 May 2019. On 20 December 2018, GeoPark proposed to extend the second exploratory period for an additional period of 18 months, ending 7 November 2020. As of the date of these consolidated financial statements the Chilean Ministry has not replied.

The investment commitment for the first exploratory period in the Campanario and Isla Norte Blocks has already been fulfilled. The investments to be made in the second exploratory period will be assumed 100% by GeoPark. On 29 May 2017, the Chilean Ministry accepted GeoPark's proposal to update the value of the commitments in both the Campanario and Isla Norte Blocks as well as the guarantees related to those commitments. Consequently, the future investment commitments assumed by GeoPark for the second exploratory period are up to:

• Campanario Block: 3 exploratory wells before 10 July 2019 (US$ 4,758,000)

• Isla Norte Block: 2 exploratory wells before 7 May 2019 (US$ 2,855,000)

As of 31 December 2018, the Group has established guarantees for its total commitments.

On 20 December 2018, GeoPark proposed to extend the second exploratory period for an additional period of 18 months, ending 11 January 2021 and 7 November 2020, respectively. As of the date of these consolidated financial statements the Chilean Ministry has not replied.

## 32.2.4 Brazil

2,200,000). As of the date of these Consolidated Financial Statements, GeoPark has already drilled the committed well, with testing expected for the first quarter of 2019.

• POT-T-747 Block: 1 exploratory well before 20 December 2018 (US$ 490,000). On 15 January 2019, the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (“ANP”) notified the suspension of the exploratory period to fulfil the commitments in the block.

• POT-T-785 Block: 3D seismic and electromagnetic survey before 29 January 2023 (US$ 90,000).

## 32.2.5 Argentina

The remaining commitment in the Sierra del Nevado Block (18% working interest) for the first exploratory period, ending on 20 August 2019, amounts to between US$ 500,000 and US$ 1,000,000 at GeoPark's working interest

The investment commitment in the CN-V Block (50% working interest) for the current exploratory period denominated as “Field under evaluation”, ending on 27 November 2021, amounts to US$ 1,300,000 at GeoPark’s working interest.

The investment commitment in the Los Parlamentos Block (50% working interest) for the first exploratory period, ending on 30 October 2021, which includes 2 exploratory wells and additional 3D seismic, amounts to US$ 6,000,000, at GeoPark's working interest.

## 32.3 Operating lease commitments – Group company as lessee

The Group leases various plant and machinery under non-cancellable operating lease agreements. The Group also leases offices under non-cancellable operating lease agreements. The lease terms are between 2 and



3 years, and most of lease agreements are renewable at the end of the lease period at market rate.

## 35.1 General

Acquisition of Non-controlling interest in Colombia and Chile's business from LG International

On 28 November 2018, GeoPark executed an agreement to acquire the LG International Corporation ("LGI") interest in GeoPark's Colombian and Chilean operations and subsidiaries.

The acquisition price includes a fixed payment of US$ 81,000,000 paid at closing, plus two equal installments of US$ 15,000,000 each, to be paid in June 2019 and June 2020. Additionally, three contingent payments of US$ 5,000,000 each could be payable over the next three years, subject to certain production thresholds being exceeded.

Through this transaction, GeoPark acquired the shares that used to be held by LGI representing 20% equity interest in GeoPark Colombia Coöperatie U.A., 20% equity interest in GeoPark Chile S.A. and 14% equity interest in GeoPark TdF S.A. In addition to that, the outstanding amount corresponding to advanced cash call payments granted in the past by LGI to GeoPark Chile



S.A. for financing Chilean operations in TdF’s blocks were considered as part of the transaction.

The transaction mentioned above has been accounted for as a transaction with non-controlling interest in accordance with IFRS 10. Consequently, the difference between the amount by which the non-controlling interest was stated and the fair value of the consideration paid was recognized directly in Equity and attributed to the owners of the Company.

The following table summarizes the result of this transaction:

## Zamuro Farm-in agreement

GeoPark executed a farm-in agreement to drill the Zamuro exploration prospect, which is located in the Llanos 32 Block (GeoPark non-operated, 12.5% WI). The farm-in agreement provided for the drilling of an exploration well to be funded by GeoPark and, in the event of a commercial discovery, GeoPark would increase its economic interest to 56.25% in the Zamuro field area. The well was spudded with unsuccessful results during 2018.

## Acquisition of Tiple Block

GeoPark executed a joint operation agreement related to certain exploration activities in an exploration acreage (“Tiple Block Acreage”) in the Llanos Basin in Colombia, through a partnership with CEPSA Colombia S.A. (a subsidiary of CEPSA SAU, the Spanish integrated energy and petrochemical company). The agreement provided for GeoPark to drill one exploration well, which was spudded with unsuccessful results during 2018.

## Incremental interest in Llanos 32 Block

On 22 August 2017, GeoPark acquired an additional 2.5% interest in the Llanos 32 Block. No gain or loss has been generated by this transaction.

## 35.3 Argentina

Acquisition of the Aguada Baguales, El Porvenir and Puesto Touquet Blocks On 27 March 2018, GeoPark acquired a 100% working interest and operatorship of the Aguada Baguales, El Porvenir and Puesto Touquet Blocks, which are located in the Neuquen Basin, for a total consideration of US$ 52,000,000, less a working capital adjustment of US$ 3,150,000. The Group has estimated that there are no any future contingent payments at the acquisition date and as of the date of these consolidated financial statements either.

In accordance with the acquisition method of accounting, the acquisition cost was allocated to the underlying assets acquired and liabilities assumed based primarily upon their estimated fair values at the date of acquisition. An income approach (being the net present value of expected future cash flows) was adopted to determine the fair values of the mineral interest. Estimates of expected future cash flows reflect estimates of projected future revenues, production costs and capital expenditures based on our business model.

The following table summarizes the combined consideration paid for the acquired blocks and the final allocation of fair value of the assets acquired and liabilities assumed for the abovementioned transaction:

<table><tr><td>Amounts in US\( &#x27;000</td><td>Total</td></tr><tr><td>Cash (a)</td><td>48,850</td></tr><tr><td>Total consideration</td><td>48,850</td></tr><tr><td>Property, plant and equipment (including mineral interest)</td><td>54,929</td></tr><tr><td>Inventories</td><td>3,659</td></tr><tr><td>Provision for other long-term liabilities</td><td>(9,738)</td></tr><tr><td>Total identifiable net assets</td><td>48,850</td></tr></table>

(a) In December 2017, GeoPark granted a security deposit of US$ 15,600,000. In March 2018, the Group completed the total consideration with an additional payment of US$ 36,400,000. In September 2018, Geo-Park collected a working capital adjustment of US$ 3,150,000.



In accordance with disclosure requirements for business combinations, the Group has calculated its consolidated revenue and profit, considering as if the mentioned acquisition had occurred at the beginning of the reporting period.

The following table summarizes both results:

<table><tr><td>Amounts in US$ &#x27;000</td><td>2018</td></tr><tr><td>Revenue</td><td>612,401</td></tr><tr><td>Profit for the period</td><td>102,873</td></tr></table>

The revenue included in the consolidated statement of comprehensive income since acquisition date contributed by the acquired business is US$ 35,879,000. The acquired business has also contributed profit of US$ 124,000 over the same period.

As a consequence of this transaction, the Group considers that there is sufficient evidence of future taxable profits to offset tax losses and recognize a deferred tax asset for US$ 1,346,000 in respect of tax losses from previous years which can be utilised against future taxable profit.

## Los Parlamentos Block

In June 2018, GeoPark acquired a 50% working interest in the Los Parlamentos exploratory block in partnership with YPF S.A. (YPF), the largest oil and gas producer in Argentina. In accordance with the partnership agreement, YPF assumed the operation of the block and GeoPark assumed a commitment to fund its 50% working interest of one exploratory well and additional 3D seismic, which amounts to US$ 6,000,000 at GeoPark's working interest, over the next three years.

## 35.4 Peru

## Entry in Peru

The Group has executed a Joint Investment Agreement and Joint Operating Agreement with Petróleos del Peru S.A. ("Petroperu") to acquire an interest in and operate the Morona Block located in northern Peru. GeoPark will assume a 75% working interest ("WI") of the Morona Block, with Petroperu retaining a 25% WI. The transaction has been approved by the Board of Directors of both Petroperu and GeoPark. The agreement was subject to Peru regulatory approval, which was completed on 1 December 2016 following the issuance of Supreme Decree 031-2016-MEM.

The Morona Block, also known as Lote 64, covers an area of 1.9 million acres on the western side of the Marañón Basin, one of the most prolific hydrocarbon basins in Peru. It contains the Situche Central oil field, which has been delineated by two wells (with short-term tests of approximately 2,400 and 5,200 bopd of 35-36° API oil each) and by 3D seismic.

In accordance with the terms of the agreement, GeoPark has committed to carry Petroperu on a work program that provides for testing and start-up production of one of the existing wells in the field, subject to certain technical and economic conditions being met. During 2017, GeoPark recognized an initial consideration owed to Petroperu of US$ 10,684,000. In 2018, after GeoPark's review and approval of supporting documentation, the consideration was reduced in US$ 806,000, resulting in a total amount of US$ 9,878,000. This amount will be offset by the Petroperu's interest in the operation expenses to be incurred by GeoPark in the block. Expected capital expenditures in 2019 for the Morona Block are mainly related to flexible pipeline installation, temporary access road, location conditioning and Morona Camp dock revamping. These activities are subject to the approval of the Environmental Impact Study, which is under review by the local authority as of the date of these consolidated financial statements.

## Note 36

## Impairment test on Property, plant and equipment

As a result of the oil price crisis which started in the second half of 2014, the Group recognized an impairment loss of US$ 149,574,000 in 2015 after evaluating the recoverability of its fixed assets affected by oil price drop, as such situation constitutes an impairment indicator according to IAS 36 and, consequently, it triggers the need of assessing the fair value of the assets involved against their carrying amount.

The Management of the Group considers as Cash Generating Unit (CGU) each of the blocks in which the Group has working or economic interests. The blocks with no material investment on fixed assets or with operations that are not linked to oil prices were not subject to the impairment test.

During 2016, 2017 and 2018 the impairment tests were reviewed. The main assumptions taken into account for the impairment tests for the blocks below mentioned were:

The future oil prices have been calculated taking into consideration the oil price curves available in the market, provided by international advisory companies, weighted through internal estimations in accordance with price curves used by D&M;

Three oil price scenarios were projected and weighted in order to minimize misleading estimations: low-price, middle-price and high-price (see below table "Oil price scenarios");

The table “Oil price scenarios” was based on Brent future price estimations; the Group adjusted this marker price on its model valuation to reflect the effective price applicable in each location (see Note 3 “Price risk”);

The model valuation was based on the expected cash flow approach;

The revenues were calculated linking price curves with levels of production according to certified reserves (see below table "Oil price scenarios");

The levels of production have been linked to certified risked 1P, 2P and 3P reserves (see Note 4);



· Production and structure costs were estimated considering internal historical data according to GeoPark's own records and aligned to the 2019 approved budget;

· The capital expenditures were estimated considering the drilling campaign necessary to develop the certified reserves;

· The assets subject to impairment test are the ones classified as Oil and Gas properties and Production facilities and machinery;

· The carrying amount subject to impairment test includes mineral interest, if any;

· The income tax charges have considered future changes in the applicable income tax rates (see Note 16).

Table Oil price scenarios \( ^{(a)} \) :

<table><tr><td rowspan="2"></td><td colspan="4">Amounts in US\( per Bbl.</td></tr><tr><td>Low price (15%)</td><td>Middle price (60%)</td><td>High price (25%)</td><td>Weighted market price used for the impairment test</td></tr><tr><td>Year</td><td></td><td></td><td></td><td></td></tr><tr><td>2019</td><td>63.9</td><td>63.9</td><td>63.9</td><td>63.9</td></tr><tr><td>2020</td><td>51.2</td><td>68.2</td><td>75.0</td><td>67.3</td></tr><tr><td>2021</td><td>53.3</td><td>71.0</td><td>78.1</td><td>70.1</td></tr><tr><td>Over 2022</td><td>55.1</td><td>73.4</td><td>80.7</td><td>72.5</td></tr></table>

(a) The percentages indicated between brackets represent the Group estimation regarding each price scenario.

As a consequence of the evaluation, the following amounts of impairment loss were reversed (recognized):

Table 4 - Reserve quantity information

## Estimated oil and gas reserves

Proved reserves represent estimated quantities of oil (including crude oil and condensate) and natural gas, which available geological and engineering data demonstrates with reasonable certainty to be recoverable in the future from known reservoirs under existing economic and operating conditions. Proved developed reserves are proved reserves that can reasonably be expected to be recovered through existing wells with existing equipment and operating methods. The choice of method or combination of methods employed in the analysis of each reservoir was determined by the stage of development, quality and reliability of basic data, and production history.
The Group believes that its estimates of remaining proved recoverable oil and gas reserve volumes are reasonable and such estimates have been prepared in accordance with the SEC Modernization of Oil and Gas Reporting rules, which were issued by the SEC at the end of 2008.

The Group estimates its reserves at least once a year. The Group’s reserves estimation as of 31 December 2018, 2017 and 2016 was based on the DeGolyer and MacNaughton Reserves Report (the “D&M Reserves Report”). DeGolyer and MacNaughton prepared its proved oil and natural gas reserve estimates in accordance with Rule 4-10 of Regulation S-X, promulgated by the SEC, and in accordance with the oil and gas reserves disclosure provisions of ASC 932 of the FASB Accounting Standards Codification (ASC) relating to Extractive Activities - Oil and Gas (formerly SFAS no. 69 Disclosures about Oil and Gas Producing Activities).

Reserves engineering is a subjective process of estimation of hydrocarbon accumulation, which cannot be exactly measured, and the reserve estimation depends on the quality of available information and the



interpretation and judgement of the engineers and geologists. Therefore, the reserves estimations, as well as future production profiles, are often different than the quantities of hydrocarbons which are finally recovered. The accuracy of such estimations depends, in general, on the assumptions on which they are based.

The estimated GeoPark net proved reserves for the properties evaluated as of 31 December 2018, 2017 and 2016 are summarized as follows, expressed in thousands of barrels (Mbbl) and millions of cubic feet (MMcf):

 \( ^{(a)} \)  For the year ended 31 December 2016, the Group’s oil and condensate proved reserves were revised upward by 7 mmbbl. The primary factors leading to the above were:

-Better than expected performance from existing wells, resulting in an increase of 9 mmbbl, of which 8 mmbbl was from the Tigana, Jacana and other minor fields in the Llanos 34 Block, and 1 mmbbl was from the Fell Block in Chile.

-Such increase was partially offset by lower average oil prices impacting the La Cuerva and Yamu Blocks in Colombia, resulting in a 2 mmbbl decrease.

 \( ^{(a)} \)  In Colombia, the extensions and discoveries are primarily due to the Jacana field appraisal wells in the Llanos 34 Block.

 \( ^{(d)} \)  For the year ended 31 December 2017, the Group’s oil and condensate proved reserves were revised upward by 4.3 mmbbl. The primary factors leading to the above were:

-Better than expected performance from existing wells, from the Tigana and Jacana fields in the Llanos 34 Block, resulting in an increase of 3.8 mmbbl. The impact of higher average oil prices resulting in a 2.5 mmbbl and 0.4 mmbbl increase in reserves from the blocks in Colombia and Chile, respectively.

-Such increase was partially offset by a decrease in reserves mainly related to a change in a previously adopted development plan in the Fell Block in Chile, resulting in a 2.4 mmbbl decrease.

 \( ^{(e)} \)  In Colombia, the extensions and discoveries are primary due to the Chiricoca, Jacamar, and Curucucu field discoveries in the Llanos 34 Block and the Tigana and Jacana field extensions in the Llanos 34 Block.

(a) For the year ended 31 December 2016, the Group's proved natural gas reserves were revised upwards by 5 billion cubic feet. This increase was mainly driven by better than expected performance from existing wells, primarily the Ache field in the Fell Block in Chile, resulting in an addition of 9 billion cubic feet. This increase was partially offset by a reduction of 4 billion cubic feet in the Pampa Larga field, also in the Fell Block.

(b) For the year ended 31 December 2017, the Group’s proved natural gas reserves were revised downwards by 13.7 billion cubic feet. This was the combined effect of:

-Removal of proved undeveloped reserves due to changes in previously adopted development plan in the Fell Block in Chile and unsuccessful proved undeveloped executions in the Fell Block in Chile (totalling 21.3 billion cubic feet).

-The above was partially offset by an increase of 6.8 billion cubic feet due to a better performance in the proved developed producing reserves in the Fell Block in Chile and the impact of higher average prices that resulted in an increase of 0.8 billion cubic feet.

(c) In Chile, the extensions and discoveries are primary due to the Uaken Field discovery in the Fell Block.

(d) For the year ended 31 December 2018, the Group’s proved natural gas reserves were revised downwards by 0.1 billion cubic feet. This was the combined effect of:

-Removal of proved undeveloped reserves due to changes in previously adopted development plan in the Fell Block in Chile and lower than expected performance from existing wells in the Fell Block in Chile (totalling 2.0 billion cubic feet).

-Lower than expected performance from existing wells in BCAM-40 Block, resulting in a decrease of 0.7 billion cubic feet.

-The above was partially offset by higher average prices that resulted in an increase of 2.5 billion cubic feet in the Fell Block in Chile.

(e) The extensions and discoveries are primary due to the Jauke Field discovery in the Fell Block, in Chile, and the gas discovery of the Une Formation in the Llanos 32 Block, in Colombia.

(f) Purchase of Minerals in place refers to the Aguada Baguales, El Porvenir, and Puesto Touquet fields acquisition during 2018. See Note 35.3 for further details.

Revisions refer to changes in interpretation of discovered accumulations and some technical and logistical needs in the area obliged to modify the timing and development plan of certain fields under appraisal and development phases.

Table 6 - Standardized measure of discounted future net cash flows related to proved oil and gas reserves

The following table discloses estimated future net cash flows from future production of proved developed and undeveloped reserves of crude oil, condensate and natural gas. As prescribed by SEC Modernization of Oil and Gas Reporting rules and ASC 932 of the FASB Accounting Standards Codification (ASC) relating to Extractive Activities – Oil and Gas (formerly SFAS no. 69 Disclosures about Oil and Gas Producing Activities), such future net cash flows were estimated using the average first day-of-the-month price during the 12-month period for 2018, 2017 and 2016 and using a 10% annual discount factor. Future development and abandonment costs include



estimated drilling costs, development and exploitation installations and abandonment costs. These future development costs were estimated based on evaluations made by the Group. The future income tax was calculated by applying the statutory tax rates in effect in the respective countries in which we have interests, as of the date this supplementary information was filed.

This standardized measure is not intended to be and should not be interpreted as an estimate of the market value of the Group’s reserves. The purpose of this information is to give standardized data to help the users of the financial statements to compare different companies and make certain projections. It is important to point out that this information does not include, among other items, the effect of future changes in prices, costs and tax rates, which past experience indicates that are likely to occur, as well as the effect of future cash flows from reserves which have not yet been classified as proved reserves, of a discount factor more representative of the value of money over the lapse of time and of the risks inherent to the production of oil and gas.
