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 benefits of the changes in our capital program or expenditures, our liquidity, the impacts of the coronavirus (COVID-19) pandemic 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, our operations are located in South America and unexpected problems can arise due to guerilla activity, strikes, local blockades or protests; technical difficulties and operational difficulties may arise which impact the production, transport or sale of our products; other disruptions to local operations; global health events (including the ongoing COVID-19 pandemic); global and regional changes in the demand, supply, prices, differentials or other market conditions affecting oil and gas, including inflation and changes resulting from a global health crisis, the Russian invasion of Ukraine, or from the imposition or lifting of crude oil production quotas or other actions that might be imposed by OPEC, such as its recent decision to cut production and other producing countries and the resulting company or third-party actions in response to such changes; changes in commodity prices, including volatility or a decline in these prices relative to historical or future expected levels; the risk that current global economic and credit conditions may impact oil prices and oil consumption more than we currently predicts, which could cause further modification of our strategy and capital spending program; prices and markets for oil and natural gas are unpredictable and volatile; the effect of hedges; the accuracy of productive capacity of any particular field; geographic, political and weather conditions can impact the production, transport or sale of our products; our ability to execute its business plan and realize expected benefits from current initiatives; the risk that unexpected delays and difficulties in developing currently owned properties may occur; the ability to replace reserves and production and develop and manage reserves on an economically viable basis; the accuracy of testing and production results and seismic data, pricing and cost estimates (including with respect to commodity pricing and exchange rates); the risk profile of planned exploration activities; the effects of drilling down-dip; the effects of waterflood and multi-stage fracture stimulation operations; the extent and effect of delivery disruptions, equipment performance and costs; actions by third parties; 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; volatility or declines in the trading price of our common stock or bonds; the risk that we do not receive the anticipated benefits of government programs, including government tax refunds; our ability to obtain a new credit agreement and comply with financial covenants in its credit agreement and indentures and make borrowings under any credit agreement; and those factors set out in Part II, Item 1A “Risk Factors” in this Quarterly Report on Form 10-Q and Part I, Item 1A “Risk Factors” in our 2022 Annual Report on Form 10-K (the “2022 Annual Report on Form 10-K”), and in our other filings with the Securities and Exchange Commission (“SEC”). The unprecedented nature of the current volatility in the worldwide economy and oil and gas industry makes it more difficult to predict the accuracy of forward-looking statements. 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 or to withdraw, 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.

(1) The current portion of the lease obligation has been included in accounts payable and accrued liabilities on the Company’s balance sheet and totaled $4.8 million as at March 31, 2023 (December 31, 2022 - $4.8 million).

As of March 31, 2023, the Company had a credit facility with a market lender in the global commodities industry. The credit facility has a borrowing base of up to $150 million, with $100 million as an initial commitment available at March 31, 2023, and an option for an additional $50 million upon mutual agreement by the Company and the lender. The credit facility bears interest based on the secured overnight financing rate posted by the Federal Reserve Bank of New York plus a credit margin of 6.00% and a credit-adjusted spread of 0.26%. Undrawn amounts under the credit facility bear interest at 2.10% per annum, based on the amount available. The credit facility is secured by the Company’s Colombian assets and economic rights. It has a final maturity date of August 15, 2024, which may be extended to February 18, 2025, upon the satisfaction of certain conditions. The availability period for the draws under the credit facility expires on August 20, 2023. As of March 31, 2023, and December 31, 2022, the credit facility remained undrawn.

Under the terms of the credit facility, the Company is required to maintain compliance with the following financial covenants:

i.Global Coverage Ratio of at least 150%, calculated using the net present value of the consolidated future cash flows of the Company up to the final maturity date discounted at 10% over the outstanding amount on the credit facility at each reporting period. The net present value of the consolidated future cash flows of the Company is required to be based on 80% of the prevailing ICE Brent forward strip.

ii.Prepayment Life Coverage Ratio of at least 150%, calculated using the estimated aggregate value of commodities to be delivered under the commercial contract from the commencement date to the final maturity date based on 80% of the prevailing ICE Brent forward strip and adjusted for quality and transportation discounts over the outstanding amount on the credit facility including interest and all other costs payable to the lender.

i.Liquidity ratio where the Company’s projected sources of cash exceed projected uses of cash by at least 1.15 times in each quarter period included in one year consolidated future cash flows. The future cash flows represent forecasted expected cash flows from operations, less anticipated capital expenditures, and certain other adjustments. The commodity pricing assumption used in this covenant is required to be 90% of the prevailing ICE Brent forward strip for the projected future cash flows.

Senior Notes

During the three months ended March 31, 2023, the Company re-purchased in the open market $8.0 million of 6.25% Senior Notes for cash consideration of $6.8 million, of which $2.6 million was included in accounts payable on the Company’s balance sheet as of March 31, 2023.

For the three months ended March 31, 2023 and 2022, there was $1.5 million and $4.6 million of stock-based compensation expense, respectively.

At March 31, 2023, there was $19.5 million (December 31, 2022 - $10.5 million) of unrecognized compensation costs related to unvested PSUs and stock options, which are expected to be recognized over a weighted-average period of 2.1 years. During the three months ended March 31, 2023, the Company paid out $15.1 million for PSUs vested on December 31, 2022 (three months ended March 31, 2022 - $2.4 million for PSUs vested on December 31, 2021).

Net (Loss) Income per Share

Basic net loss or income per share is calculated by dividing net loss or income attributable to common shareholders by the weighted average number of shares of common stock issued and outstanding during each period.

Diluted net loss or income per share is calculated using the treasury stock method for share-based compensation arrangements. The treasury stock method assumes that any proceeds obtained on the exercise of share-based compensation arrangements would be used to purchase common shares at the average market price during the period. The weighted average number of shares is then adjusted by the difference between the number of shares issued from the exercise of share-based compensation arrangements and shares re-purchased from the related proceeds. Anti-dilutive shares represent potentially dilutive securities excluded from the computation of diluted loss or income per share as their impact would be anti-dilutive.

For the three months ended March 31, 2023, and 2022, on a weighted average basis, all options and 5,331,160 options, respectively, were excluded from the diluted (loss) income per share calculation as the options were anti-dilutive.

6. Revenue

The Company’s revenues are generated from oil sales at prices that reflect the blended prices received upon shipment by the purchaser at defined sales points or defined by contract relative to ICE Brent and adjusted for Vasconia, Oriente or Castilla crude differentials, quality and transportation discounts and premiums each month. For the three months ended March 31, 2023, 100% (three months ended March 31, 2022 - 100%) of the Company’s revenue resulted from oil sales. During the three months ended March 31, 2023, quality and transportation discounts were 22% of the average ICE Brent price (three months ended March 31, 2022 - 13%).

During the three months ended March 31, 2023, the Company’s production was sold primarily to one major customer in Colombia, representing 97% of the total sales volumes (three months ended March 31, 2022 - two customers, representing 57% and 43% of the total sales volumes).

As at March 31, 2023, accounts receivable included $3.2 million of accrued sales revenue related to March 2023 production (December 31, 2022 - nil related to December 2022 production).

7. Taxes

The Company's effective tax rate was 142% for the three months ended March 31, 2023, compared to 74% in the comparative period of 2022. Current income tax expense was $17.6 million for the three months ended March 31, 2023, compared to $20.8 million in the corresponding period of 2022, primarily due to a decrease in taxable income.

The deferred income tax expense for the three months ended March 31, 2023, was $15.3 million mainly the result of tax depreciation being higher than accounting depreciation and the use of tax losses to offset taxable income in Colombia. The deferred income tax expense in the comparative period of 2022 was $18.7 million as the result of tax depreciation being higher compared to accounting depreciation in Colombia.

For the three months ended March 31, 2023, the difference between the effective tax rate of 142% and the 50% Colombian tax rate was primarily due to an increase in non-deductible foreign translation adjustments, the impact of foreign taxes, non-deductible royalty in Colombia and increase in the valuation allowance. These were partially offset by other permanent differences.

For the three months ended March 31, 2022, the difference between the effective tax rate of 74% and the 35% Colombian tax rate was primarily due to an increase in the impact of foreign taxes, foreign translation adjustments, increase in the valuation allowance, other permanent differences, and non-deductible stock-based compensation.

8. Contingencies

Legal Proceedings

Gran Tierra has several lawsuits and claims pending. The outcome of the lawsuits and disputes cannot be predicted with certainty; Gran Tierra 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 as they are incurred or become probable and determinable.

Letters of credit and other credit support

At March 31, 2023, the Company had provided letters of credit and other credit support totaling $109.6 million (December 31, 2022 - $111.1 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

Financial instruments are initially recorded at fair value, defined as the price that would be received to sell an asset or paid to market participants to settle liability at the measurement date. For financial instruments carried at fair value, 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 representing quoted market prices in active markets for identical assets and liabilities

•Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the assets and liabilities, either directly or indirectly

•Level 3 - Unobservable inputs for assets and liabilities

At March 31, 2023, the Company’s financial instruments recognized on the balance sheet consist of cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, other long-term assets, accounts payable and accrued liabilities, other short-term payables, long-term debt, short-term and long-term equity compensation reward liability and other long-term liabilities. The Company uses appropriate valuation techniques based on the available information to measure the fair values of assets and liabilities.

Fair Value Measurement

The following table presents the Company’s fair value measurements of its financial instruments as of March 31, 2023, and December 31, 2022:


	As at March 31, 2023		As at December 31, 2022

PSUs liability - long-term(3)	2,630		9,941
	$	10,641	$	25,023

(1) The long-term portion of restricted cash and PEF is included in the other long-term assets on the Company’s balance sheet

(2) The current portion of PEF is included in the other current assets on the Company’s balance sheet

(3) Long-term DSUs and PSUs liabilities are included in the long-term equity compensation award liability on the Company’s balance sheet

The fair values of cash and cash equivalents, current restricted cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their carrying amounts due to the short-term maturity of these instruments.

Restricted cash - long-term

The fair value of long-term restricted cash and cash equivalents approximated their carrying value because interest rates are variable and reflective of market rates.

Prepaid Equity Forward (“PEF”)

To reduce the Company’s exposure to changes in the trading price of the Company’s common shares on outstanding PSUs and DSUs, the Company entered into a PEF. At the end of the term, the counterparty will pay the Company an amount equivalent to the notional amount of the shares using the price of the Company’s common shares at the valuation date. The Company has the discretion to increase or decrease the notional amount of the PEF or terminate the agreement early. As at March 31, 2023, the Company’s PEF had a notional amount of 10 million shares with a fair value of $8.9 million (As at December 31, 2022 - 16 million shares with a fair value of $16.0 million). During the three months ended March 31, 2023, the Company recorded a $1.7 million loss on the PEF in general and administrative expenses (three months ended March 31, 2022- $7.8 million gain). The

fair value of the PEF asset was estimated using the Company’s share price quoted in active markets at the end of each reporting period.

DSUs liability

The fair value of DSUs liability was estimated using the Company’s share price quoted in active markets at the end of each reporting period.

PSUs liability

The fair value of the PSUs liability was estimated based on a pricing model using inputs such as Company’s share price and PSUs performance factor.

Senior Notes

Financial instruments not recorded at fair value at March 31, 2023, were the Senior Notes (Note 4).

At March 31, 2023, the carrying amounts of the 6.25% Senior Notes and the 7.75% Senior Notes were $268.5 million and $293.6 million, respectively, which represented the aggregate principal amount less unamortized debt issuance costs, and the fair values were $233.6 million and $235.5 million, respectively.

During the three months ended March 31, 2023, the Company did not incur any gains or losses related to derivatives (three months ended March 31, 2022 - $21.4 million loss related to commodity price derivatives).

(2) Non-GAAP measures

Operating netback, EBITDA, adjusted EBITDA, and funds flow from operations are non-GAAP measures that 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 oil sales, net (loss) 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. Disclosure of each non-GAAP financial measure is preceded by 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 sales less operating 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 sales to operating netback is provided in the table above.

EBITDA, as presented, is defined as net (loss) income adjusted for depletion, depreciation and accretion (“DD&A”) expenses, interest expense and income tax expense. Adjusted EBITDA, as presented, is defined as EBITDA adjusted for non-cash lease expense, lease payments, unrealized foreign exchange gain or loss, stock-based compensation expense or recovery, unrealized derivative instruments gain or loss, inventory impairment, gain on re-purchase of Senior Notes and other financial instruments gain. 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 (loss) income to EBITDA and adjusted EBITDA is as follows:

Oil production NARfor the three months ended March 31, 2023, increased by 12% to 25,526 from the corresponding period of 2022 due to successful drilling and workover campaigns in all major fields and production from Ecuador during the current quarter. Oil production NAR was comparable to prior quarter.

Royalties as a percentage of production for the three months ended March 31, 2023, decreased to 19% compared to the corresponding period of 2022 and the prior quarter commensurate with the decrease in benchmark oil prices and the price sensitive royalty regime in Colombia.

The Midas block includes the Acordionero, Chuira, and Ayombero oil fields, and the Chaza block includes the Costayaco and Moqueta oil fields.

Realized price per bbl for thethree months ended March 31, 2023, decreased by 25% compared to the corresponding period of 2022, mainly as a result of a 16% decrease in Brent price and higher differentials. Castilla and Vasconia differentials increased to $15.17 per bbl and $7.87 per bbl from $6.38 per bbl and $3.60 per bbl, respectively, in the corresponding period of 2022. Compared to the prior quarter, the average realized price per bbl decreased by 8%, primarily due to a 7% decrease in Brent price.

Oil sales for the three months ended March 31, 2023, decreased by 17% to $144.2 million compared to the corresponding period of 2022 due to a 16% decrease in Brent price and higher Castilla and Vasconia differentials. Additionally, during the three months ended March 31, 2023, we commenced oil sales in Ecuador, which contributed $3.2 million to oil sales and were subject to a $13.89 per bbl Oriente differential.

Compared to the prior quarter, oil sales decreased by 11%, primarily as a result of a 7% decrease in Brent price and a 2% decrease in sales volumes.

The following table shows the effect of changes in realized price and sale volumes on our oil sales for the three months ended March 31, 2023, compared to the prior quarter and the corresponding period of 2022:


(Thousands of U.S. Dollars)	First Quarter 2023 Compared with Fourth Quarter 2022		First Quarter 2023 Compared with First Quarter 2022

Operating expenses for the three months ended March 31, 2023, increased by 18% to $41.4 million or by $1.19 per bbl to $18.26 per bbl, compared to the corresponding period of 2022, primarily as a result of $1.23 per bbl higher lifting costs, $0.81 per bbl of which were attributed to Ecuador operations with the remainder associated with higher equipment rental in Colombia required for testing new exploration wells, partially offset by $0.04 per bbl lower workovers.

Compared to the prior quarter, operating expenses decreased by 10% or $1.27 per bbl from $46.1 million or $19.53 per bbl, primarily due to $1.08 per bbl lower workover activities and $0.19 per bbl lower lifting costs attributed to lower road maintenance activities, partially offset by operating costs incurred in Ecuador and higher equipment rental during the current quarter.

Transportation expenses

We have options to sell our oil through multiple pipelines and trucking routes. Each option has varying effects on realized sales price and transportation expenses. The following table shows the percentage of oil volumes we sold in Colombia and Ecuador using each option for the three months ended March 31, 2023, and 2022, and the prior quarter:


	Three Months Ended March 31,				Three Months Ended December 31,
	2023		2022		2022
Volume transported through pipeline	2	%	—	%	—	%
Volume sold at wellhead	45	%	47	%	48	%
Volume transported via truck to sales point	53	%	53	%	52	%
	100	%	100	%	100	%

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

Transportation expenses for the three months ended March 31, 2023, increased by 8% to $3.1 million, compared to the corresponding period of 2022 due to the utilization of new transportation routes for Ecuador sales and exploration wells brought online during the current quarter.

On a per bbl basis, transportation expenses decreased by 3% to $1.35 for the three months ended March 31, 2023, compared to the corresponding period of 2022 due to higher sales volumes in the current quarter.

Transportation expenses increased by 26% from $2.4 million in the prior quarter due to new transportation routes utilized for Ecuador sales and higher sales volumes transported via truck, which resulted in higher transportation costs per bbl in the current quarter.

DD&A expenses for the three months ended March 31, 2023, increased by 26% or by $2.81 per bbl due to increased production and higher costs in the depletable base compared to the corresponding period of 2022.

DD&A expenses were comparable to the prior quarter and increased by $0.90 per bbl when compared to the prior quarter, due to lower production and a higher costs in the depletable base.

G&A Expenses


	Three Months Ended March 31,					Three Months Ended December 31,

G&A Expenses, Including Stock-Based Compensation	$	5.60	$	6.03	(7)	$	4.52

For the three months ended March 31, 2023, G&A expenses before stock-based compensation increased by 44% to $11.2 million or by $1.14 per bbl to $4.94 per bbl due to higher costs attributed to optimization projects and lease obligations expenses associated with additional leases when compared to the corresponding period of 2022.

G&A expenses after stock-based compensation for the three months ended March 31, 2023, increased by 3% or $0.43 per bbl due to a lower share price compared to the corresponding period of 2022.

Compared to the prior quarter, G&A expenses before stock-based compensation increased by 40% or $1.55 on a per bbl basis for the same reason mentioned above.

Compared to the prior quarter, G&A expenses after stock-based compensation increased by 19% or $1.08 on a per bbl basis for the same reason as mentioned above, partially offset by lower stock-based compensation resulting from a lower share price in the first quarter of 2023.

Foreign Exchange Gains and Losses

For the three months ended March 31, 2023, we had a loss on foreign exchange of $1.7 million, compared to a $3.7 million gain in the corresponding period of 2022 and a $2.1 million loss in the prior quarter. Accounts receivable, taxes receivable, deferred income taxes, accounts payable, and prepaid equity forward (“PEF”) are considered monetary items and require translation from local currencies to U.S. dollar functional currency at each balance sheet date. This translation was the primary source of the foreign exchange gains and losses in the periods.

The following table presents the change in the U.S. dollar against the Colombian peso and Canadian dollar for the three months ended March 31, 2023, and 2022:

We spud 10 development and four water injection wells, of which eight were in Midas Block and six in Chaza. Of the development wells spud during the quarter, six were completed, and four were in-progress as of March 31, 2023. During the three months ended March 31, 2023, we have not spud any wells in Ecuador.

Liquidity and Capital Resources

(Thousands of U.S. Dollars)	March 31, 2023		% Change	December 31, 2022
Cash and Cash Equivalents	$	105,684	(17)	$	126,873

7.75% Senior Notes	$	300,000	—	$	300,000

We believe that our capital resources, including cash on hand, cash generated from operations and available borrowings under the credit facility, will provide us with sufficient liquidity to meet our strategic objectives and planned capital program for the next 12 months, given the current oil price trends and production levels. We may also access capital markets to pursue financing or refinance our Senior Notes. 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 with the flexibility to respond to both internal growth opportunities and those available through acquisitions. We intend to pursue growth opportunities and acquisitions from time to time, which may require significant capital, be located in basins or countries beyond our current operations, involve joint ventures, or be sizable compared to our current assets and operations.

At March 31, 2023, we had a credit facility with a market lender in the global commodities industry. The credit facility has a borrowing base of up to $150 million, with $100 million readily available at March 31, 2023, and a potential option for an additional $50 million of borrowings upon mutual agreement by the lender and us. The credit facility bears interest based on a risk-free rate posted by the Federal Reserve Bank of New York plus a margin of 6.00% and a credit-adjusted spread of 0.26%. Undrawn amounts under the credit facility bear interest at 2.10% per annum, based on the amount available. The credit facility is secured by our Colombian assets and economic rights. It has a final maturity date of August 15, 2024, which may be extended to February 18, 2025, upon the satisfaction of certain conditions. The availability period for the draws under the credit facility expires on August 20, 2023. As of March 31, 2023, the credit facility remained undrawn.

Under the terms of the credit facility, we are required to maintain compliance with the following financial covenants:

i.Coverage ratio of at least 150%, calculated using the net present value of the consolidated future cash flows of the Company up to the final maturity date discounted at 10% over the outstanding amount on the credit facility at each reporting period. The net present value of the consolidated future cash flows of the Company is required to be based on 80% of the prevailing ICE Brent forward strip.

ii.Prepayment Life Coverage Ratio of at least 150%, calculated using the estimated aggregate value of commodities to be delivered under the commercial contract from the commencement date to the final maturity date based on 80% of the prevailing ICE Brent forward strip, adjusted for quality and transportation discounts over the outstanding amount on the credit facility including interest and all other costs payable to the lender.

iii.Liquidity ratio where the Company’s projected sources of cash exceed projected uses of cash by at least 1.15 times in each quarter period included in one year consolidated future cash flows. The future cash flows represent forecasted expected cash flows from operations, less anticipated capital expenditures and certain other adjustments. The commodity pricing assumption used in this covenant is required to be 90% of the prevailing Brent strip forward for the projected future cash flows.

At March 31, 2023, we had a $271.9 million aggregate principal amount of 6.25% Senior Notes due 2025 and a $300.0 million aggregate principal amount of 7.75% Senior Notes due 2027 outstanding.

During the three months ended March 31, 2023, we repurchased in the open market $8.0 million of 6.25% Senior Notes for cash consideration of $6.8 million, which resulted in a $1.1 million gain on re-purchase which included the write-off of deferred financing fees of $0.1 million. The re-purchased 6.25% Senior Notes were not cancelled and held by us as treasury bonds as of March 31, 2023.

During the year ended December 31, 2022, we implemented a share re-purchase program (the “2022 Program”) through the facilities of the Toronto Stock Exchange (“TSX”) and eligible alternative trading platforms in Canada. Under the 2022 Program, we are able to purchase at prevailing market prices up to 36,033,969 shares of Common Stock, representing approximately 10% of the issued and outstanding shares of Common Stock as of August 22, 2022. The 2022 Program expires on August 31, 2023, or earlier if the 10% share maximum is reached. Re-purchases are subject to prevailing market conditions, the trading price of our Common Stock, our financial performance and other conditions.

During the three months ended March 31, 2023, we re-purchased 13,082,115 shares at a weighted average price of $0.82 per share. The re-purchased shares were held by us recorded as treasury stock. As of March 31, 2023, the Company held 35,829,577 treasury stock shares (December 31, 2022 - 22,747,462).

(1) Adjusted EBITDA and funds flow from operations are non-GAAP measures which do 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.

One of the primary sources of variability in our cash flows from operating activities is the fluctuation in oil prices. Sales volume changes, costs related to operations and debt service also impact cash flows. Our cash flows from operating activities are also impacted by foreign currency exchange rate changes. During the three months ended March 31, 2023, funds flow from operations decreased by 31% compared to the corresponding period of 2022, primarily due to a decrease in Brent price, higher quality and transportation discounts, and higher operating costs.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are disclosed in Item 7 of our 2022 Annual Report on Form 10-K and have not changed materially since the filing of that document.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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. Our revenues are from oil sales at ICE Brent adjusted for quality differentials.

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 adjusted for quality differentials. 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 value added taxes, operating and G&A expenses in Colombia are in the 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.

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

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 credit facility, which bears floating rates of interest. At March 31, 2023, our outstanding balance under the credit facility was nil (December 31, 2022 - nil).

Item 4. Controls and Procedures

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, 2023.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2023, that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.

PART II - Other Information

Item 1. Legal Proceedings

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, 2022, and any material matters that have arisen since the filing of such report.

Item 1A. Risk Factors

There are numerous factors that affect our business and results of operations, many of which are beyond our control. In addition to information set forth in this quarterly report on Form 10-Q, including in Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, you should carefully read and consider the factors set out in Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022. These risk factors could materially affect our business, financial condition and results of operations. The unprecedented nature of the current pandemic and the volatility in the worldwide economy and oil and gas industry may make it more difficult to identify all the risks to our business, results of operations and financial condition and the ultimate impact of identified risks.
