Record Oil and Gas Production

Record Oil and Gas Reserves

Record Oil and Gas Asset Valuation – Total and Per Share

Record Capital Investment and Cost Efficiencies

Record Cash Flow/Adjusted EBITDA Growth

Strengthened Balance Sheet and Credit Rating

New Acreage/Projects Acquired and New Strategic Acquisition Partnership Announced

James F. Park, Chief Executive Officer of GeoPark, said: “Our team has GeoPark firing on all cylinders. Through good science and engineering, we found and produced more oil and gas. Through innovation and efficiencies, we reduced our capital and operating costs. Through organic cash flows, we self-funded our work and investment program. Through effective capital allocation, every dollar of new investment created multiples of net present value. Through engagement with our neighbors and conscientious operations, we operated safely, cleanly and without interruption. Through regional knowledge and scouting, we acquired new high-impact acreage and projects. Through a rewarding and motivating workplace, we were able to train and attract talented people to continue to build our capabilities for the future. Through efforts to more widely share our performance story, we were the number one performing E&P stock on the NYSE. Our team now has a proven 15-year track record of continuous growth, but we feel we are just getting warmed up for the big opportunities coming our way.”

Production: Significant oil production growth of 39% in Colombia increased average consolidated oil and gas production to 30,654 boepd in 4Q2017 from 23,593 boepd in 4Q2016. The increase was mainly attributed to new oil production from the Tigana/Jacana oil fields in Llanos 34 block in Colombia. On a consolidated basis, gas production increased by 11% compared to 4Q2016, primarily attributed to increased industrial demand in Brazil.

For further detail, please refer to 4Q2017 Operational Update published on January 10, 2018.

Reference and Realized Oil Prices: Brent crude oil price averaged $61.5 per bbl during 4Q2017, and the consolidated realized oil sales price averaged $43.0 per bbl in 4Q2017, representing a 24% increase from $34.6 per bbl in 3Q2017 and a 38% increase from $31.2 per bbl in 4Q2016. Differences between reference and realized prices are a result of commercial and transportation discounts as well as the Vasconia price differential in Colombia, which averaged $4.0 per bbl in 4Q2017 from $2.8 per bbl in 3Q2017 and $5.7 per bbl in 4Q2016. Commercial and transportation discounts in Colombia were reduced to $14.9 per bbl in 4Q2017 from $15.2 per bbl in 3Q2017 and $15.0 per bbl in 4Q2016.

Company efforts are currently underway to continue improving realized oil prices, including negotiation of existing conditions with off-takers plus construction of a flowline and related facilities in Llanos 34 block, expected to continue improving current commercial and transportation discounts.

The following table provides a breakdown of reference and net realized oil prices in Colombia and Chile in 4Q2017:

Revenue: Higher oil and gas production and pricing drove total consolidated revenues up by 76% to $106.3 million in 4Q2017, compared to $60.3 million in 4Q2016.

Sales of crude oil : Consolidated oil revenues increased by 87% to $92.2 million in 4Q2017, driven by a 35% increase in oil sales volumes and a 38% increase in realized oil prices. Oil revenues represented 87% of total revenues compared to 82% in 4Q2016.

Sales of gas : Consolidated gas revenues increased by 28% to $14.1 million in 4Q2017 compared to $11.0 million in 4Q2016 due to 15% higher realized gas prices and 11% higher gas sales volumes.

Commodity risk management contracts: Consolidated commodity risk management contracts registered a realized loss of $5.8 million in 4Q2017, totaling realized losses of $2.1 million in full year 2017 ($3.8 million cash gains were recorded and cashed-in during the first nine months of 2017). Unrealized cash losses amounted to $12.6 million in 4Q2017 compared to $3.1 million loss in 4Q2016 resulting from the significant increase in forward Brent oil price curve. The company uses risk management contracts to minimize the impact of oil price fluctuations on the Company´s self-funded work program.

Production and operating costs ^[1] : Consolidated operating costs per barrel decreased by 9% to $7.3 per boe in 4Q2017 from $8.1 per boe in 4Q2016. Following the 30% increase in oil and gas sales volumes, total operating costs increased by $3.0 million to $19.6 million. Consolidated royalties increased by $6.8 million to $10.7 million in 4Q2017, mainly as the Jacana oil field in the Llanos 34 block accumulated more than five million barrels of production that triggered Colombia’s “high price” royalty scheme beginning in 2Q2017, and to a lesser extent due to increased volumes and higher realized prices.

Below is a breakdown of production and operating costs by country:

Selling expenses: Consolidated selling expenses decreased to $0.3 million in 4Q2017 compared to $0.6 million in 4Q2016.

Administrative, Geological and Geophysical expenses: Consolidated G&A and G&G expenses increased by 15% to $14.5 million in 4Q2017 compared to $12.6 million in 4Q2016 mainly due to higher staff costs resulting from an increased scale of operations. Consolidated G&A and G&G costs per boe decreased by 13% to $5.5 per boe in 4Q2017 (vs. $6.1 per boe in 4Q2016).

Adjusted EBITDA: Consolidated adjusted EBITDA of $55.2 million was more than two times higher than the $27.0 million in 4Q2016. That is the equivalent of $20.6 per barrel and was driven by the combination of increased production and higher realized oil and gas prices.

____________________

^[1] Production and Operating Costs = Operating Costs plus Royalties

The table below shows production, volumes sold and breakdown of the most significant components of adjusted EBITDA for 4Q2017 and 4Q2016, on a per country and per barrel basis:

Depreciation: Consolidated depreciation increased by 17% to $19.8 million in 4Q2017, compared to $16.9 million in 4Q2016, due to higher volumes sold. On a per barrel basis, however, depreciation costs were lower given drilling successes and increased reserves. Depreciation costs per boe decreased by 10% to $7.4 per boe.

Write-off of unsuccessful exploration efforts: Consolidated write-off of unsuccessful exploration efforts was $1.1 million in 4Q2017, compared to $17.7 million in 4Q2016. Amounts recorded in 4Q2017 mainly correspond to unsuccessful exploration efforts in non-operated Sierra del Nevado and Puelen blocks in Argentina.

Impairment of Non-Financial Assets: Consolidated non-cash impairment of non-financial assets was zero in 4Q2017 compared to a $5.7 million gain in 4Q2016 ($5.7 million non-cash recovery in Colombia).

Other expenses: Other operating expenses were $2.7 million in 4Q2017, compared to $0.9 million in 4Q2016.

CONSOLIDATED NON-OPERATING RESULTS AND PROFIT FOR THE PERIOD

Net financial expenses: Net financial costs decreased by 7% to $8.2 million in 4Q2017, compared to $8.9 million in 4Q2016, mainly resulting from lower bank charges and other financial results.

Foreign exchange: Net foreign exchange charges were a $3.6 million loss in 4Q2017 and $1.4 million loss in 4Q2016, mainly due to the devaluation of the Brazilian Real over the US Dollar-denominated net debt incurred at the local subsidiary level, where the Real is the functional currency.

Income tax: Income taxes amounted to a $10.7 million in 4Q2017, as compared to a $9.7 million in 4Q2016, in line with higher taxable profits in 4Q2017.

Net income: Net losses amounted to $3.4 million in 4Q2017 compared to $26.0 million in 4Q2016. The net loss in 4Q2017 resulted from unrealized hedge charges.

BALANCE SHEET

Cash and cash equivalents: Cash and cash equivalents totaled $134.8 million as of December 31, 2017 compared to $73.6 million a year earlier. The difference reflects cash generated from operating activities of $142.2 million and cash from financing activities of $24.0 million, partially offset by cash used in investing activities of $105.6 million.

Cash generated from operating activities of $142.2 million is net of a $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 Neuquen basin in Argentina, which is expected to close in March 2018.

Cash from financing activities of $24.0 million includes net proceeds from the issuance of 2024 Notes of $418.3 million, offset by: (i) principal paid of $355.0 million related to the payment of 2020 Notes and the prepayment of the Itau loan, (ii) cancellation costs of $12.3, and (iii) interest payments of $27.7 million.

Cash used in investing activities of $105.6 million (76% allocated to Colombia) includes capital expenditures related to development, appraisal and exploration activities carried out in 2017 that allowed GeoPark to increase its reserves with low finding and development costs of $3.6/boe for 1P and $4.0/boe for 2P reserves (or $2.4/boe and $2.8/boe for 1P and 2P, respectively in Colombia).

Financial debt: Total financial debt (net of issuance costs) amounted to $426.2 million, including the $425 million 2024 Notes issued in September 2017. Short-term debt amounted to $7.7 million as of December 31, 2017.

Issuance of 2024 Notes: During September 2017, the Company successfully placed $425 million notes (“2024 Notes”). The 2024 Notes carry a coupon of 6.50% per annum. Funds were used to repay financial debt, to provide financial flexibility and for general corporate purposes.

The indenture governing the 2024 Notes includes incurrence test covenants that require the net debt to adjusted EBITDA ratio be lower than 3.5 times and the adjusted EBITDA to interest ratio higher than 2 times until September 2019. Failure to comply with the incurrence test covenants would not trigger an event of default. As of the date of this release the Company is in compliance with all provisions and covenants.

Rounding amounts and percentages: Certain amounts and percentages included in this press release have been rounded for ease of presentation. Percentage figures included in this press release have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. For this reason, certain percentage amounts in this press release may vary from those obtained by performing the same calculations using the figures in the financial statements. In addition, certain other amounts that appear in this press release may not sum due to rounding.

This press release contains certain oil and gas metrics, including information per share, operating netback, reserve life index, and others, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies. Such metrics have been included herein to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods.

CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION

This press release contains statements that constitute forward-looking statements. Many of the forward-looking statements contained in this press release can be identified by the use of forward-looking words such as ‘‘anticipate,’’ ‘‘believe,’’ ‘‘could,’’ ‘‘expect,’’ ‘‘should,’’ ‘‘plan,’’ ‘‘intend,’’ ‘‘will,’’ ‘‘estimate’’ and ‘‘potential,’’ among others.

Forward-looking statements that appear in a number of places in this press release include, but are not limited to, statements regarding the intent, belief or current expectations, regarding various matters, including expected 2018 production growth and performance, operating netback per boe and capital expenditures plan. Forward-looking statements are based on management’s beliefs and assumptions, and on information currently available to the management. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors.

Forward-looking statements speak only as of the date they are made, and the Company does not undertake any obligation to update them in light of new information or future developments or to release publicly any revisions to these statements in order to reflect later events or circumstances, or to reflect the occurrence of unanticipated events. For a discussion of the risks facing the Company which could affect whether these forward-looking statements are realized, see filings with the U.S. Securities and Exchange Commission.

Oil and gas production figures included in this release are stated before the effect of royalties paid in kind, consumption and losses. Annual production per day is obtained by dividing total production for 365 days.

Information about oil and gas reserves : The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proven, probable and possible reserves that meet the SEC's definitions for such terms. GeoPark uses certain terms in this press release, such as "PRMS Reserves" that the SEC's guidelines do not permit GeoPark from including in filings with the SEC. As a result, the information in the Company’s SEC filings with respect to reserves will differ significantly from the information in this press release.

NPV10 for PRMS 1P, 2P and 3P reserves is not a substitute for the standardized measure of discounted future net cash flows for SEC proved reserves.

The reserve estimates provided in this release are estimates only, and there is no guarantee that the estimated reserves will be recovered. Actual reserves may eventually prove to be greater than, or less than, the estimates provided herein. Statements relating to reserves are by their nature forward-looking statements.

Adjusted EBITDA: The Company defines adjusted EBITDA as profit for the period before net finance costs, income tax, depreciation, amortization and certain non-cash items such as impairments and write-offs of unsuccessful exploration and evaluation assets, accrual of stock options stock awards, unrealized results on commodity risk management contracts and other non-recurring events. Adjusted EBITDA is not a measure of profit or cash flows as determined by IFRS. The Company believes 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. The Company excludes 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, none of which are components of adjusted EBITDA. The Company’s 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 or corresponding period, see the accompanying financial tables.

Operating netback per boe 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 Operating Netback per boe 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, none of which are components of Operating Netback per boe. The Company’s computation of Operating Netback per boe may not be comparable to other similarly titled measures of other companies. For a reconciliation of Operating Netback per boe to the IFRS financial measure of profit for the year or corresponding period, see the accompanying financial tables.
