CAUTIONARY LANGUAGE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements other than statements of historical facts included in this Quarterly Report on Form 10-Q regarding our financial position, estimated quantities and net present values of reserves, business strategy, plans and objectives of our management for future operations, covenant compliance, capital spending plans and those statements preceded by, followed by or that otherwise include the words “believe”, “expect”, “anticipate”, “intend”, “estimate”, “project”, “target”, “goal”, “plan”, “budget”, “objective”, “could”, “should”, or similar expressions or variations on these expressions are forward-looking statements. We can give no assurances that the assumptions upon which the forward-looking statements are based will prove to be correct or that, even if correct, intervening circumstances will not occur to cause actual results to be different than expected. Because forward-looking statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by the forward-looking statements. There are a number of risks, uncertainties and other important factors that could cause our actual results to differ materially from the forward-looking statements, including, but not limited to, sustained or future declines in commodity prices; potential future impairments and reductions in proved reserve quantities and value; our operations are located in South America, and unexpected problems can arise due to guerilla ~~activity;~~activity and other local conditions; technical difficulties and operational difficulties may arise which impact the production, transport or sale of our products; geographic, political and weather conditions can impact the production, transport or sale of our products; ~~the risk that current global economic and credit conditions may impact oil prices and oil consumption more than we currently predict;~~ our ability to raise capital; our ability to identify and complete successful acquisitions; our ability to execute business plans; ~~the risk that~~ unexpected delays and difficulties in developing currently owned properties may occur; the timely receipt of regulatory or other required approvals for our operating activities; the failure of exploratory drilling to result in commercial wells; unexpected delays due to the limited availability of drilling equipment and personnel; ~~the risk that~~ current global economic and credit market conditions may impact oil prices and oil consumption ~~more~~differently than we currently predict, which could cause us to further modify our strategy and capital spending program; those factors set out in Part I, Item 1A “Risk Factors” in our 2018 Annual Report on Form 10-K, as amended (the "2018 Annual Report on Form 10-K"), and in our other filings with the Securities and Exchange Commission (“SEC”). The information included herein is given as of the filing date of this Quarterly Report on Form 10-Q with the SEC and, except as otherwise required by the federal securities laws, we disclaim any obligation or undertaking to publicly release any updates or revisions to any forward-looking statement contained in this Quarterly Report on Form 10-Q to reflect any change in our expectations with regard thereto or any change in events, conditions or circumstances on which any forward-looking statement is based.

GLOSSARY OF OIL AND GAS TERMS

In this document, the abbreviations set forth below have the following meanings:



bbl	barrel	BOE	barrels of oil equivalent
bopd	barrels of oil per day	BOEPD	barrels of oil equivalent per day
Mcf	thousand cubic feet	NAR	net after royalty

Sales volumes represent production NAR adjusted for inventory changes. Our oil and gas reserves are reported NAR. Our production is also reported NAR, except as otherwise specifically noted as "working interest production before royalties." Natural gas liquids ("NGLs") volumes are converted to BOE on a one-to-one basis with oil. Gas volumes are converted to BOE at the rate of 6 Mcf of gas per bbl of oil, based upon the approximate relative energy content of gas and oil. The rate is not necessarily indicative of the relationship between oil and gas prices. BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf:1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

Notes to the Condensed Consolidated Financial Statements (Unaudited)

(Expressed in U.S. Dollars, unless otherwise indicated)

1. Description of Business

Gran Tierra Energy Inc., a Delaware corporation (the “Company” or “Gran Tierra”), is a publicly traded company focused on oil and natural gas exploration and production in Colombia and Ecuador.

2. Significant Accounting Policies

These interim unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). The information furnished herein reflects all normal recurring adjustments that are, in the opinion of management, necessary for the fair presentation of results for the interim periods.

The note disclosure requirements of annual consolidated financial statements provide additional disclosures to that required for interim unaudited condensed consolidated financial statements. Accordingly, these interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements as at and for the year ended December 31, 2018, included in the Company’s 2018 Annual Report on Form 10-K.

The Company’s significant accounting policies are described in Note 2 of the consolidated financial statements which are included in the Company’s 2018 Annual Report on Form 10-K and are the same policies followed in these interim unaudited condensed consolidated financial statements, except as noted below. The Company has evaluated all subsequent events through to the date these interim unaudited condensed consolidated financial statements were issued.

Recently Adopted Accounting Pronouncements

Leases

The Company adopted Accounting Standard Codification ("ASC") 842 Leases with a date of initial application on January 1, 2019 in accordance with the modified retrospective transition approach using the practical expedients available for land easements and short-term leases. The Company did not elect the "suite" of practical expedients or use the hindsight expedient in its adoption.

At inception of a contract, the Company assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. At inception of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease and non-lease component on the basis of their relative stand-alone prices. The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, and subsequently at cost less any accumulated depreciation and impairment losses, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company's incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate. The lease liability is subsequently increased by the interest cost on the lease liability and decreased by lease payments made. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, a change in the estimate of the amount expected to be payable under a residual value guarantee, or as appropriate, changes in the assessment of whether a purchase or extension option is reasonably certain to be exercised or a termination option is reasonably certain not to be exercised.

The Company has applied judgment to determine the lease term for contracts which include renewal or termination options. The assessment of whether the Company is reasonably certain to exercise such options impacts the lease term, which significantly affects the amount of lease liabilities and right-of-use assets recognized.

All leases identified relate to office leases.

The transition resulted in the recognition of a right-of-use asset presented in other capital assets of $3.8 million at January 1, 2019, the recognition of lease liabilities of $4.2 million and a $0.4 million impact on retained earnings. When measuring the lease liabilities, the Company's incremental borrowing rate was used. At January 1, 2019 the rates applied ranged between 5.6% and 9.1%.

3. Property, Plant and Equipment

On February 20, 2019, the Company acquired 36.2% working interest ("WI") in the Suroriente Block and a 100% WI of the Llanos-5 Block for cash consideration of $79.1 million and a promissory note of $1.5 million included in current accounts payable on the Company's condensed consolidated balance sheet. The cost of the assets was allocated to proved ~~assets~~properties using relative fair values. The entire consideration of $0.3 million for Llanos-5 was allocated to unproved ~~assets.~~properties.

Net Income per Share

Basic net income per share is calculated by dividing net income by the weighted average number of shares of Common Stock and exchangeable shares issued and outstanding during each period. Diluted net income per share is similarly calculated except that the common shares outstanding for the period is increased using the treasury stock method to reflect the potential dilution that could occur if outstanding stock awards were vested at the end of the applicable period plus potentially issuable shares on conversion of the convertible notes. Anti-dilutive shares represent potentially dilutive securities that are excluded from the computation of diluted income or loss per share as their impact would be anti-dilutive.

6. Revenue

~~Most of the~~The Company's revenues are generated from oil sales at prices which reflect the blended prices received upon shipment by the purchaser at defined sales points or are defined by contract relative to ICE Brent and adjusted for Vasconia or Castilla crude differentials, quality, and transportation discounts each month. For the three and six months ended ~~March 31,~~June 30, 2019, 100% (three and six months ended ~~March 31,~~June 30, 2018 - 100%) of the Company's revenue resulted from oil sales. During the three and six months

ended ~~March 31,~~June 30, 2019, quality and transportation discounts were ~~17%~~13% and 15%, respectively, of the average ICE Brent price (three and six months ended ~~March 31,~~June 30, 2018 - ~~16%)~~14% and 15%, respectively). During the three and six months ended ~~March 31,~~June 30, 2019, the Company's production was sold primarily to ~~two~~three major customers in Colombia (three and six months ended ~~March 31,~~June 30, 2018 - ~~four)~~three).

As at ~~March 31,~~June 30, 2019, accounts receivable included ~~$4.3~~$3.0 million of accrued sales revenue related to ~~March~~June 2019 production (December 31, 2018 - $4.2 million related to December 31, 2018 production).

7. Taxes

The Company's effective tax rate was ~~91% in~~46% for the ~~three~~six months ended ~~March 31,~~June 30, 2019, compared ~~with 59%~~to 58% in the comparative period inof 2018. Current income tax ~~expenses were~~expense was lower in the ~~three~~six months ended ~~March 31,~~June 30, 2019, compared with the corresponding period inof 2018, primarily as a result of lower ~~taxable~~Colombian income and higher tax depreciation in Colombia. The deferred income tax expense of ~~$8.3~~$23.3 million ~~for~~was lower in the ~~three~~six months ended ~~March 31,~~June 30, 2019, ~~was~~compared to the corresponding period of 2018 primarily due to lower excess tax depreciation compared with accounting depreciation in Colombia, a reduction in the Colombian tax rate and a reduction to the valuation allowance in Colombia.

For the ~~three~~six months ended ~~March 31,~~June 30, 2019, the difference between the effective tax rate of ~~91%~~46% and the 33% Colombian tax rate was primarily due to foreign currency translation adjustments and an increase in the valuation allowance, foreign translation adjustment, a non-deductible third party royalty in Colombia, stock-based compensation and other permanent differences. These were partially offset by a decrease in the impact of foreign taxes.allowance.

For the comparative period in 2018, the ~~59%~~58% effective tax rate differed from the Colombian tax rate of 37% primarily due to ~~an increase to~~ the ~~valuation allowance, non-deductible third party royalty in Colombia,~~impact of foreign tax rates, stock based compensation, foreign currency translation adjustments and ~~other permanent differences. These were partially offset by a decrease~~an increase in the ~~impact of foreign taxes.~~valuation allowance.

8. Contingencies

Legal Proceedings

The Agencia Nacional de Hidrocarburos (National Hydrocarbons Agency) ("ANH") and Gran Tierra are engaged in ongoing discussions regarding the interpretation of whether certain transportation and related costs are eligible to be deducted in the calculation of an additional royalty (the "HPR royalty"). Based on the Company's understanding of the ANH's position, the estimated compensation, which would be payable if the ANH’s interpretation is correct, could be up to $55.6 million as at ~~March~~June 30, 2019 (December 31, ~~2019.~~2018 - $56.3 million). At this time no amount has been accrued in the interim unaudited condensed consolidated financial statements as Gran Tierra does not consider it probable that a loss will be incurred.

In addition to the above, the Company has a number of other lawsuits and claims pending. Although the outcome of these other lawsuits and disputes cannot be predicted with certainty, the Company believes the resolution of these matters would not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. Gran Tierra records costs associated with these lawsuits and claims as they are incurred or become probable and determinable.

Letters of credit and other credit support

At ~~March 31,~~June 30, 2019, the Company had provided letters of credit and other credit support totaling ~~$77.1~~$122.5 million (December 31, 2018 - $76.7 million) as security relating to work commitment guarantees in Colombia and Ecuador contained in exploration contracts and other capital or operating requirements.

9. Financial Instruments and Fair Value Measurement

Financial Instruments

At ~~March 31,~~June 30, 2019, the Company’s financial instruments recognized in the balance sheet consisted of: cash and cash equivalents; restricted cash and cash equivalents; accounts receivable; investment; ~~derivatives,~~ accounts payable and accrued liabilities, derivatives, long-term debt, equity compensation award liability and other long-term liabilities.

Fair Value Measurement

The fair value of investment, derivatives and PSU ~~liabilities~~liability is remeasured at the estimated fair value at the end of each reporting period.

The fair value of the short-term portion of the Company's investment in PetroTal Corp. ("PetroTal"), which was received on the sale of the Company's Peru business unit, was estimated using quoted prices at ~~March 31,~~June 30, 2019, and the foreign exchange rate at that date. PetroTal is a publicly-traded energy company incorporated and domiciled in Canada engaged in exploration, appraisal and development of crude oil and natural gas in Peru, South America. PetroTal's shares are listed on the Toronto Stock Exchange Venture under the trading symbol 'TAL' and on the London Stock Exchange under the trading symbol 'PTAL'. Gran Tierra directly and indirectly holds approximately 246 million common shares representing approximately 37% of PetroTal's issued and outstanding common shares. Gran Tierra has the right to nominate two directors to the board of PetroTal. The fair value of the long-term portion of the investment restricted by escrow conditions was estimated using observable and unobservable inputs; factors that were evaluated included quoted market prices, precedent comparable transactions, risk free rate, measures of market risk volatility, estimates of the Company's and PetroTal’s cost of capital and quotes from third parties.

The fair value of commodity price and foreign currency derivatives is estimated based on various factors, including quoted market prices in active markets and quotes from third parties. The Company also performs an internal valuation to ensure the reasonableness of third party quotes. In consideration of counterparty credit risk, the Company assessed the possibility of whether the counterparty to the derivative would default by failing to make any contractually required payments. Additionally, the Company considers that it is of substantial credit quality and has the financial resources and willingness to meet its potential repayment obligations associated with the derivative transactions.

The fair value of the PSU liability was estimated based on option pricing model using inputs such as quoted market prices in an active market, and PSU performance factor.

The fair value of investment, derivatives ~~PSU~~ and ~~DSU liabilities~~equity compensation award liability (PSU and DSU) at ~~March 31,~~June 30, 2019, and December 31, 2018, was as follows:

~~These losses are presented as financial instruments loss in the condensed consolidated statements of operations and cash flows.~~

Investment ~~loss~~gain for the three and six months ended ~~March 31,~~June 30, 2019, was related to the fair value ~~loss~~gain on the PetroTal shares Gran Tierra received in connection with the sale of its Peru business unit in December 2017. For the three and six months ended ~~March 31,~~June 30, 2019 and 2018, this investment ~~loss~~gain was unrealized.

Financial instruments not recorded at fair value include the Company's 6.25% Senior Notes due 2025 (the ~~"Senior~~"6.25% Senior Notes") and 7.75% Senior Notes and the Convertible ~~Notes (Note 4).~~Notes. At ~~March 31,~~June 30, 2019, the carrying amounts of the 6.25% Senior Notes, the 7.75% Senior Notes and the Convertible Notes were ~~$289.6~~$290.0 million, $289.2 million and ~~$112.4~~$112.7 million, respectively, which represented the aggregate principal amount less unamortized debt issuance costs, and the fair values were ~~$286.8~~$280.5 million, $294.8 million and ~~$119.0~~$123.6 million, respectively. The fair value of long-term restricted cash and cash equivalents and the revolving credit facility approximated their carrying value because interest rates are variable and reflective of market rates. The fair values of other financial instruments approximate their carrying amounts due to the short-term maturity of these instruments.

GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy consists of three broad levels. Level 1 inputs consist of quoted prices (unadjusted) in active markets for identical assets and liabilities and have the highest priority. Level 2 and 3 inputs are based on significant other observable inputs and significant unobservable inputs, respectively, and have lower priorities. The Company uses appropriate valuation techniques based on the available inputs to measure the fair values of assets and liabilities.

At ~~March 31,~~June 30, 2019, the fair value of the current portion of the investment and DSU liability was determined using Level 1 inputs, the fair value of derivatives and PSUs was determined using Level 2 inputs and the fair value of the long-term portion of the investment restricted by escrow conditions was determined using Level 3 inputs. The table below presents the fair value of the long-term portion of the investment:



	Six Months Ended			Year Ended
(Thousands of U.S. Dollars)	June 30, 2019			December 31, 2018
Opening balance, investment - long-term	$	8,711		$	19,147

Unrealized valuation gain	1,394			846
Unrealized foreign exchange gain (loss)	428			(760		)
Closing balance, investment - long-term	$	6,181		$	8,711

With all other variables held constant, a $0.01 change in the CAD price of PetroTal shares would result in a $1.9 million change in the total investment in PetroTal as at June 30, 2019.

Three Months Ended Year Ended

Closing balance, investment - long-term $ 8,513
$ 8,711

The Company uses available market data and valuation methodologies to estimate the fair value of debt. The fair value of debt is the estimated amount the Company would have to pay a third party to assume the debt, including a credit spread for the difference between the issue rate and the period end market rate. The credit spread is the Company’s default or repayment risk. The credit spread (premium or discount) is determined by comparing the Company’s Senior Notes, Convertible Notes and revolving credit facility to new issuances (secured and unsecured) and secondary trades of similar size and credit statistics for both public and private debt. The disclosure above regarding the fair value of the Convertible Notes was determined using Level 2 inputs based on the indicative pricing published by certain third-party services or trading levels of the Convertible Notes, which are not listed on any securities exchange or quoted on an inter-dealer automated quotation system. The disclosure in the paragraph above

regarding the fair value of cash and restricted cash and cash equivalents, revolving credit facility and Senior Notes was based on Level 1 inputs.

The Company’s non-recurring fair value measurements include asset retirement obligations. The fair value of an asset retirement obligation is measured by reference to the expected future cash outflows required to satisfy the retirement obligation discounted at the Company’s credit-adjusted risk-free interest rate. The significant level 3 inputs used to calculate such liabilities include estimates of costs to be incurred, the Company’s credit-adjusted risk-free interest rate, inflation rates and estimated dates of abandonment. Accretion expense is recognized over time as the discounted liabilities are accreted to their expected settlement value, while the asset retirement cost is amortized over the estimated productive life of the related assets.

Commodity Price Derivatives

The Company utilizes commodity price derivatives to manage the variability in cash flows associated with the forecasted sale of its oil production, reduce commodity price risk and provide a base level of cash flow in order to assure it can execute at least a portion of its capital spending.

At ~~March 31,~~June 30, 2019, the Company had outstanding commodity price derivative positions as follows:

Financial and Operational Highlights

Key Highlights for the ~~first~~second quarter of 2019

Net after royalties production ("NAR") was ~~31,664~~29,193 BOEPD, ~~12%~~4% higher than the ~~first~~second quarter of 2018. Production increased largely due to production from development activities in the Acordionero Field, a decrease in royalties driven by lower oil prices and the acquisition of additional WIworking interest ("WI") in Suroriente Block

The production increases were partially offset by the temporary suspension of Suroriente production due to community blockades from June17 through July 9, 2019, and, starting late May 2019, downtime from ESP failures in Acordionero and the temporary shut-in of two large producers in Acordionero with high gas oil ratio ("GOR"). The successful commissioning of water injection facilities in Acordionero in July 2019 and associated increase in water injection is

expected to reduce the GOR in the field and the planned transition to gas to power in August 2019 is expected to reduce ESP failures due to unreliable power. Both activities in Acordionero are expected to allow us to restore production in the coming months

Oil and natural gas sales volumes were ~~31,833~~29,277 BOEPD, ~~17%~~5% higher than the ~~first~~second quarter of 2018. The quarter's increase in oil and gas sales volumes was due to ~~increase in production, decrease in royalties driven by lower oil prices, and~~ the reduction of inventory

Net income was ~~$2.0~~$38.5 million compared with ~~$17.9~~$20.3 million in the ~~first~~second quarter of 2018


•	Funds flow from operations⁽²⁾ ~~increased~~ decreased by 1%7% to ~~$75.5~~$88.3 million compared with the ~~first~~second quarter of 2018, while Brent price decreased 5%9% from the ~~first~~second quarter of 2018

~~EBITDA was $92.5 million compared with $88.6 million in the first quarter of 2018~~

~~Active quarter with capital expenditures of $94 million~~

~~Oil and gas sales per BOE were $53.25, 6% lower than the first quarter of 2018~~


•	EBITDA⁽²⁾ was $115.3 million compared with $102.3 million in the second quarter of 2018


•	Q2 2019 was an active quarter with capital expenditures of $99.6 million


•	Oil and gas sales per BOE were $59.30, 8% lower than the second quarter of 2018


•	Operating netback⁽²⁾ per BOE was ~~$36.08~~$40.02 for the ~~first~~second quarter 2019

Operating expenses per BOE were ~~$12.14, 37%~~$12.66, 20% higher than the ~~first~~second quarter of 2018 as a result of higher power generation, field operations maintenance and equipment rental costs

Workover expenses per BOE were ~~$2.20, 20%~~$4.79, 46% higher compared to the ~~first~~second quarter of 2018 as a result of ~~electric~~ submersible ~~pumps failure~~pump failures during the ~~first~~second quarter of 2019

Quality and transportation discount per BOE was ~~$10.65~~$9.02 compared with ~~$10.72~~$10.53 in the ~~first~~second quarter of 2018; this ~~$0.07~~$1.51 per BOE reduction resulted from renegotiation of several sales agreements which use Castilla differential and smaller fixed discount during the ~~optimization of transportation routes and narrowing of differentials~~

~~Transportation expenses per BOE were $2.83, comparable with the first~~second quarter of ~~2018~~

~~General~~2019 opposed to using Vasconia and ~~administrative ("G&A") expenses before stock-based compensation per BOE decreased by 16% to $2.75 compared with~~higher fixed discount in the ~~first~~sales agreements during the second quarter of 2018


•	Transportation expenses per BOE were $1.83, compared to $2.57 per BOE for the second quarter of 2018

Announced a new country entry into Ecuador's Oriente Basin by securing 100% WI in three highly prospective exploration blocks via successful bids in a bidding round, creating a contiguous acreage position extending from Gran Tierra's existing assets in Colombia's Putumayo Basin, contingent upon regulatory approvals and the execution of the Participation Contracts expected in May 2019

~~Subsequent to the quarter, increased the WI in the VMM-2 Block to 100%~~

⁽²⁾Non-GAAP measures

Operating netback, EBITDA and funds flow from operations are non-GAAP measures which do not have any standardized meaning prescribed under GAAP. Management views these measures as financial performance measures. Investors are cautioned that these measures should not be construed as alternatives to net income or other measures of financial performance as determined in accordance with GAAP. Our method of calculating these measures may differ from other companies and, accordingly, may not be comparable to similar measures used by other companies. Each non-GAAP financial measure is presented along with the corresponding GAAP measure so as not to imply that more emphasis should be placed on the non-GAAP measure.

Operating netback, as presented, is defined as oil and natural gas sales less operating, workover and transportation expenses. Management believes that operating netback is a useful supplemental measure for management and investors to analyze financial performance and provides an indication of the results generated by our principal business activities prior to the consideration of other income and expenses. A reconciliation from oil and natural gas sales to operating netback is provided in the table above.

EBITDA, as presented, is defined as net income adjusted for depletion, depreciation and accretion ("DD&A") expenses, interest expense and income tax expense. Management uses this supplemental measure to analyze performance and income generated by our principal business activities prior to the consideration of how non-cash items affect that income, and believes that this financial measure is useful supplemental information for investors to analyze our performance and our financial results. A reconciliation from net income to EBITDA is as follows:

Funds flow from operations, as presented, is defined as net income adjusted for DD&A expenses, deferred tax expense, stock-based compensation expense, amortization of debt issuance costs, cash settlement of RSUs, non-cash lease expense, lease payments, unrealized foreign exchange gains and losses, financial instruments gains or losses and cash settlement of financial ~~instruments and loss on sale.~~instruments. Management uses this financial measure to analyze performance and income generated by our principal business activities prior to the consideration of how non-cash items affect that income or loss, and believes that this financial measure is also useful supplemental information for investors to analyze performance and our financial results. A reconciliation from net income to funds flow from operations is as follows:

Oil and Gas Production and Sales Volumes, BOEPD

Oil and gas production NAR for the three and six months ended ~~March 31,~~June 30, 2019 increased by ~~12%,~~4% and 8% respectively, compared with the corresponding ~~period~~periods of 2018. The increase in production was a result of successful drilling and a workover campaign in the Acordionero ~~Field.~~Field and acquisition of additional WI in Suroriente Block during the first quarter of 2019. These increases were partially offset by the temporary suspension of Suroriente production due to community blockades from June 17 through July 9, 2019, and, starting late May 2019, downtime from ESP failures in Acordionero and the temporary shut-in of two large producers in Acordionero with high GOR. The successful commissioning of water injection facilities in Acordionero in July 2019 and associated increase in water injection is expected to reduce the GOR in the field and the planned transition to gas to power in August 2019 is expected to reduce ESP failures due to unreliable power. Both activities in Acordionero are expected to allow us to restore production in the coming months.

Royalties as a percentage of production for the three and six months ended ~~March 31,~~June 30, 2019 decreased compared with the corresponding ~~period~~periods of 2018 commensurate with the decrease in benchmark oil prices ~~due to~~and the price sensitive ~~royalties payable~~royalty regime in Colombia.

Average realized prices for the three and six months ended ~~March 31,~~June 30, 2019 decreased ~~by 6%~~8% and 7%, respectively, compared with the corresponding ~~period~~periods of 2018. The decrease was commensurate with decreases in benchmark oil prices partially offset by lower quality and transportation discounts.

We have options to sell our oil through multiple pipelines and trucking routes. Each transportation route has varying effects on realized sales prices and transportation expenses and we primarily focus on maximizing operating netback. The following table shows the percentage of oil volumes we sold in Colombia using each transportation method for the three and six months ended ~~March 31,~~June 30, 2019 and 2018, and the prior quarter:

Volumes transported through pipeline or via truck receive higher realized prices, but incur higher transportation expenses. Volumes sold at the wellhead have the opposite effect of lower realized prices, offset by lower transportation expenses.

Transportation expenses for the three and six months ended ~~March 31,~~June 30, 2019 ~~increased by 16%~~decreased 25% and 4% to ~~$8.1~~$4.9 and $13.0 million, respectively, compared with the corresponding ~~period~~periods of 2018.

Net Income and Funds Flow from Operations (a Non-GAAP Measure)

⁽¹⁾Funds flow from operations is a non-GAAP measure which does not have any standardized meaning prescribed under GAAP. Refer to "Financial and Operational Highlights—non-GAAP measures" for a definition and reconciliation of this measure.

Capital expenditures during the three months ended ~~March 31,~~June 30, 2019 were ~~$94.5~~$99.6 million:

Liquidity and Capital Resources

We believe that our capital resources, including cash on hand, cash generated from operations and available capacity on our credit facility, will provide us with sufficient liquidity to meet our strategic objectives and planned capital program for 2019, given current oil price trends and production levels. ~~We may also pursue financing through capital markets.~~ In accordance with our investment policy, available cash balances are held in our primary cash management banks or may be invested in U.S. or Canadian government-backed federal, provincial or state securities or other money market instruments with high credit ratings and short-term liquidity. We believe that our current financial position provides us the flexibility to respond to both internal growth opportunities and those available through acquisitions.

Under the terms of our credit facility and Senior Notes, we are required to maintain compliance with certain financial and operating covenants which include: limitations on our ratio of debt to net income plus interest, taxes, depreciation, depletion, amortization, exploration expenses and all non-cash charges minus all non-cash income ("EBITDAX") to a maximum of 4.0 to 1.0 (under the credit facility) and 3.5 to 1.0 (under the Senior Notes); the maintenance of a ratio of EBITDAX to interest expense of at least 2.5 to 1.0 (definitions of debt, EBITDAX and other relevant terms are per the credit agreement or the indenture governing the Senior Notes and may differ between these agreements). As at ~~March 31,~~June 30, 2019, we were in compliance with all financial and operating covenants in these agreements. Under the terms of the credit facility and Senior Notes, we are also limited in our ability to make distributions to our shareholders.

In Colombia, we participate in a special exchange regime, and we receive revenue in U.S. dollars offshore. We may also pay invoices denominated in U.S. dollars for our Colombian business from these U.S. dollars received offshore.

One of the primary sources of variability in our cash flows from operating activities is the fluctuation in oil prices, the impact of which we partially mitigate by entering into commodity derivatives. Sales volume changes and costs related to operations and

debt service also impact cash flow. Our cash flows from operating activities are also impacted by foreign currency exchange rate changes, the impact of which we partially mitigate by entering into foreign currency derivatives.

Off-Balance Sheet Arrangements

Contractual Obligations

On May 20, 2019, we issued $300 million aggregate principal amount of the 7.75% Senior Notes. Refer to Note 4 in the Notes to the Condensed Consolidated Financial Statements (Unaudited) in Part I, Item 1 of this Form 10-Q.

During the ~~three~~six months ended ~~March 31,~~June 30, 2019, we re-paid a balance of ~~$3.0~~$163 million outstanding under our revolving credit facility, which was undrawn as at ~~March 31,~~June 30, 2019.

Subsequent to June 30, 2019, ~~had $114.0~~we purchased and canceled $114,997,000 aggregate principal amount of Convertible Notes at a purchase price of $1,075 in cash per $1,000 principal amount of Convertible Notes plus $1.6 million ~~drawn.~~of accrued and unpaid interest outstanding on such Convertible Notes up to, but not excluding the date of purchase

Critical Accounting Policies and Estimates

We adopted Accounting Standard Codification ("ASC") 842 Leases with a date of initial application on January 1, 2019 in accordance with the modified retrospective transition approach using the practical expedients available for land easements and short-term leases. We did not elect the "suite" of practical expedients or use the hindsight expedient in its adoption.

The transition resulted in the recognition of a right-of-use asset presented in other capital assets of $3.8 million, the recognition of lease liabilities in other long-term liabilities of $4.2 million and a $0.4 million impact on retained earnings. When measuring the lease liabilities, the Company's incremental borrowing rate was used. At January 1, 2019 the average rates applied were between 5.6% and 9.1%.

At inception of a contract, we assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. At inception of a contract that contains a lease component, we allocate the consideration in the contract to each lease and non-lease component on the basis of their relative stand-alone prices. We recognize a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, and subsequently at cost less any accumulated depreciation and impairment losses, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our incremental borrowing rate. Generally, we use the Company's incremental borrowing rate as the discount rate. The lease liability is subsequently increased by the interest cost on the lease liability and decreased by lease payments made. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, a change in the estimate of the amount expected to be payable under a residual value guarantee, or as appropriate, changes in the assessment of whether a purchase or extension option is reasonably certain to be exercised or a termination option is reasonably certain not to be exercised.

Commodity price risk

Our principal market risk relates to oil prices. Oil prices are volatile and unpredictable and influenced by concerns over world supply and demand imbalance and many other market factors outside of our control. Most of our revenues are from oil sales at prices which reflect the blended prices received upon shipment by the purchaser at defined sales points or are defined by contract relative to ICE Brent and adjusted for quality each month.

We have entered into commodity price derivative contracts to manage the variability in cash flows associated with the forecasted sale of our oil production, reduce commodity price risk and provide a base level of cash flow in order to assure we can execute at least a portion of our capital spending.

Foreign currency risk

Foreign currency risk is a factor for our company but is ameliorated to a certain degree by the nature of expenditures and revenues in the countries where we operate. Our reporting currency is U.S. dollars and 100% of our revenues are related to the U.S. dollar price of Brent or WTI oil. We receive 100% of our revenues in U.S. dollars and the majority of our capital expenditures is in U.S. dollars or is based on U.S. dollar prices. The majority of income and value added taxes and G&A expenses in Colombia are in local currency. Certain G&A expenses incurred at our head office in Canada are denominated in Canadian dollars. While we operate in South America exclusively, the majority of our acquisition expenditures have been valued and paid in U.S. dollars.

We have entered into foreign currency derivative contracts to manage the variability in cash flows associated with our forecasted Colombian peso denominated costs.

Additionally, foreign exchange gains and losses result primarily from the fluctuation of the U.S. dollar to the Colombian peso due to our current and deferred tax liabilities, which are monetary liabilities, denominated in the local currency of the Colombian foreign operations. As a result, a foreign exchange gain or loss must be calculated on conversion to the U.S. dollar functional currency.

Interest rate risk is the risk that future cash flows will fluctuate as a result of changes in market interest rates. We are exposed to interest rate fluctuations on our revolving credit facility, which bears floating rates of interest. At ~~March 31,~~June 30, 2019, our outstanding balance under revolving credit facility was ~~$114.0 million~~nil (December 31, 2018 - nil).

See Note 9 in the Notes to the Condensed Consolidated Financial Statements (Unaudited) in Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated herein by reference, for further information regarding our derivative contracts, including the notional amounts and call and put prices by expected (contractual) maturity dates. Expected cash flows from the derivatives equaled the fair value of the contract. The information is presented in U.S. dollars because that is our reporting currency. We do not hold any of these derivative contracts for trading purposes.

Disclosure Controls and Procedures

We have established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, or Exchange Act). Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by Gran Tierra in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report, as required by Rule l3a-15(b) of the Exchange Act. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that Gran Tierra's disclosure controls and procedures were effective as of ~~March 31,~~June 30, 2019.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended ~~March 31,~~June 30, 2019, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - Other Information

See Note 8 in the Notes to the Condensed Consolidated Financial Statements (Unaudited) in Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated herein by reference, for any material developments with respect to matters previously reported in our Annual Report on Form 10-K for the year ended December 31, 2018, and any material matters that have arisen since the filing of such report.

Item 1A. Risk Factors

See Part I, Item 1A Risk Factors of our 2018 Annual Report on Form 10-K. Other than the risk factor set forth below, there have been no material changes to the risks ~~facing our company have not changed materially from those~~ set forth in Part I, Item 1A Risk Factors of our 2018 Annual Report on Form 10-K.

We have recently been awarded exploration rights on blocks in Ecuador.

~~While we~~We have recently been awarded exploration rights on blocks in ~~Ecuador, contracts related to such exploration rights have not yet been signed.~~Ecuador. We have not previously operated in Ecuador, and it is difficult to predict the results and to project the costs of implementing an exploratory drilling program in Ecuador due to the inherent uncertainties of drilling and the fact that exploration and production operations there are subject to legal, social, political and economic uncertainties that may be different from what we have experienced in Colombia. Ecuador has experienced and may in the future experience political and economic instability. This instability could result in new governments or the adoption of new policies, laws or regulations that might assume a substantially more hostile attitude toward foreign investment, including but not limited to: the imposition of additional taxes; nationalization; changes in energy or environmental policies or the personnel administering them; and changes in oil and natural gas pricing policies. In an extreme case, such a change could result in termination of contract rights and expropriation of foreign-owned assets or renegotiation or nullification of existing concessions and contracts. Any changes in the oil and gas or investment regulations and policies or a shift in political attitudes in Ecuador are beyond our control and may significantly hamper our ability to expand our operations or operate our business in this country at a profit. Wells that are drilled may not achieve the results expected.

⁽²⁾Exclusive of commissions paid to the broker to repurchase the Common Stock.

⁽³⁾ On March 7, 2018, we announced that we intended to implement a share repurchase program (the “2018 Program”) through the facilities of the TSX and eligible alternative trading platforms in Canada. We received regulatory approval from the TSX to commence the 2018 Program on March 12, 2018. We were able to purchase at prevailing market prices up to 19,269,732 shares of Common Stock, representing approximately 5% of our issued and outstanding shares of Common Stock, until the 2018 Program expired on March 11, 2019.

~~Shares purchased pursuant to the 2019 Program to date have been canceled.~~

The 2019 Program will expire on March 12, 2020, or earlier if the 5.00% share maximum is reached. The 2019 Program could be terminated by us at any time, subject to compliance

with regulatory requirements. As such, there can be no assurance regarding the total number of shares that may be repurchased under the 2019 Program. Of the shares repurchased, 4,338,400 shares have not been cancelled by the Company and are designated as treasury stock as at June 30, 2019.
