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 activity of the Company and its subsidiaries (the “Group” or “GeoPark”) is the exploration, development and production for oil and gas reserves in Colombia, Chile, Brazil, Argentina and Peru.

This condensed consolidated interim financial report was authorised for issue by the Board of Directors on 8 August 2018.

Basis of Preparation

The condensed consolidated interim financial report of GeoPark Limited is presented in accordance with IAS 34 “Interim Financial Reporting”. It does not include all of the information required for full annual financial statements, and should be read in conjunction with the annual financial statements as at and for the years ended 31 December 2016 and 2017, which have been prepared in accordance with IFRS.

The condensed consolidated interim financial report has been prepared in accordance with the accounting policies applied in the most recent annual financial statements , except for the changes explained in Note 15. For further information please refer to GeoPark Limited's consolidated financial statements for the year ended 31 December 2017.

Whenever necessary, certain comparative amounts have been reclassified to conform to changes in presentation in the current period.

Taxes on income in the interim periods are accrued using the tax rate that would be applicable to expected total annual profit or loss.

The activities of the Group are not subject to significant seasonal changes.

Estimates

The preparation of interim financial information 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. Actual results may differ from these estimates.

In preparing these condensed consolidated interim financial statements, the significant judgements made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements for the year ended 31 December 2017.

Note 2

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 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 exploration 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 to the Executive Committee is measured in a manner consistent with that in the financial statements.

Six-months period ended 30 June 2018

A reconciliation of total Operating netback to total profit before income tax is provided as follows:

^(c) Includes Peru and Corporate.

Note 4

Commodity risk management contracts

The Group 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 30 June 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.

The following table presents the Group’s derivative contracts in force as of 30 June 2018:

The table below summarizes the gain (loss) on the commodity risk management contracts:

The following table presents the Group’s derivative contracts agreed after the balance sheet date:

GeoPark’s share capital only consists of common shares. The authorized share capital consists of 5,171,949,000 common shares of par value US$ 0.001 per share. All of the Company issued and outstanding common shares are fully paid and nonassessable. The company also has an employee incentive program, pursuant to which it has granted share awards to its senior management and certain key employees (see Notes 26 and 30 to the audited Consolidated Financial Statements as of 31 December 2017).

Classified as follows:

Note 12 (Continued)

Borrowings (Continued)

(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 pledge of all of the equity interests of the Company, directly or indirectly, in 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 interim condensed consolidated financial statements, the Company is in compliance of all the indenture’s provisions and covenants.

(b) During February 2016, GeoPark 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 final maturity on February 2019.

As of the date of these interim condensed consolidated financial statements, the Group has available credit lines for over US$ 50,000,000.

Note 15

Changes in accounting policies

This note explains the impact of the adoption of IFRS 9 Financial Instruments and IFRS 15 Revenue form Contracts with Customers on the Group’s Consolidated Financial Statements and also discloses the new accounting policies that have been applied from 1 January 2018, where they are different to those applied in prior periods.

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 and a reclassification of measurement category, but no adjustments to the amounts recognised in the Consolidated Financial Statements.

Note 15 (Continued)

Changes in accounting policies (Continued)

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 30 June 2018, the Group holds no money market funds.

From 1 January 2018, the Group applies the following accounting policy in relation to its financial assets.

Financial assets are divided into the following categories: amortised 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 recognised 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 recognised in the Consolidated Statement of Income when receivable, regardless of how the related carrying amount of financial assets is measured.

Amortised 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 amortised cost using the effective interest method, less provision for impairment, if applicable.

Any change in their value through impairment or reversal of impairment is recognised in the Consolidated Statement of Income. All of the Group’s financial assets are classified as amortised cost.

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 recognised from initial recognition of the receivables.

The Group has adopted IFRS 15 from 1 January 2018, which resulted in no changes in accounting policies or adjustments to the amounts recognised in the consolidated financial statements.

Note 16

Fair value measurement of financial instruments

Accounting policies for financial instruments have been applied to classify as either: amortised cost, fair value through other comprehensive income, 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.

(a) Fair value hierarchy

The following table presents the Group’s financial assets and financial liabilities measured and recognised at fair value at 30 June 2018 and 31 December 2017 on a recurring basis:

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 30 June 2018.

Note 16 (Continued)

Fair value measurement of financial instruments (Continued)

(b) Valuation techniques used to determine fair values

Specific valuation techniques used to value financial instruments include:

(c) 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 Group estimates that the fair value of its main financial liabilities is approximately 99.9% of its carrying amount including interests accrued as of 30 June 2018. Fair values were calculated using discounted cash flow analysis.

Note 17

Capital commitments

Capital commitments are detailed in Note 32 (b) to the audited Consolidated Financial Statements as of 31 December 2017. The following updates have taken place during the six-month period ended 30 June 2018:

Argentina

The second exploratory well was drilled in the CN-V Block, with completion and testing expected for the third quarter of the year. As of 30 June 2018, the remaining commitment amounts to US$ 2,200,000.

Brazil

The Brazilian National Agency of Petroleum, Natural Gas and Biofuels (“ANP”) extended the first exploratory period to fulfill our commitments in the SEAL-T-268 y REC-T-94 Blocks until 7 February 2020. The remaining commitments in the blocks amounts to US$ 160,000 and US$ 970,000, respectively.

Note 17 (Continued)

Capital commitments (Continued)

Brazil (Continued)

GeoPark was awarded one exploratory block, POT-T-785, in the Potiguar Basin. The assumed commitment is equivalent to acquiring 3D Seismic and performing geochemical analysis for a total amount of approximately US$ 400,000, during the first exploratory period ending 29 January 2023.

As of the date of these interim condensed consolidated financial statements, the Group has already fulfilled its commitments in the POT-T-619 Block.

Note 18

Business transactions

Argentina - 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 working capital adjustment of US$ 3,150,000.

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 excess of acquisition cost, if any, over the net identifiable assets acquired represents goodwill.

The purchase price allocation performed is preliminary, since the valuation process is ongoing. This process will be completed during 2018.

The following table summarises the combined consideration paid for the acquired blocks, the preliminary allocation of fair value of the assets acquired and liabilities assumed for these transactions:

Note 18 (Continued)

Business transactions (Continued)

Argentina - Aguada Baguales, El Porvenir and Puesto Touquet blocks (Continued)

In accordance with disclosure requirements for business combinations, the Group has calculated its revenue and profit, considering as if the mentioned acquisition had occurred at the beginning of the reporting period. The following table summarises both results:

The revenue included in the consolidated statement of comprehensive income since acquisition date contributed by the acquired business is US$ 13,057,000. The acquired business has also contributed profit of US$ 1,342,000 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 recognise 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.

Argentina - Los Parlamentos block

On 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 operationship of the block and GeoPark assumed a commitment to fund its 50% working interest of one exploration well and additional 3D seismic, which amounts to US$ 6,000,000 at GeoPark’s working interest, over the next three years.
