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 with assets currently in Colombia, Ecuador and Canada.

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 audited consolidated financial statements provide additional disclosures 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, 2024, included in the Company’s 2024 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 2024 Annual Report on Form 10-K and are the same policies followed in these interim unaudited condensed consolidated financial statements. The Company has evaluated all subsequent events to the date these interim unaudited condensed consolidated financial statements were issued.

Recently Adopted Accounting Pronouncements

In December 2023, FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures”. ASU 2023-09 enhances the income tax disclosures to enable investors to better understand entity’s exposure to potential changes in jurisdictional tax legislation and associated risks and opportunities, income tax information that effects cash flow forecasts and potential opportunities to increase future cash flows. This ASU is effective for annual reporting periods beginning after December 15, 2024 and should be applied prospectively, with retrospective application permitted. The Company adopted ASU 2023-09 effective January 1, 2025. The implementation of this update did not have a material impact on income tax disclosures.

3. Business Combination

On October 31, 2024, the Company acquired all of the issued and outstanding common shares of i3 Energy Plc (“i3 Energy”), subsequently renamed as Gran Tierra UK Limited (“Gran Tierra UK”) for $ 204.5 million, consisting of cash consideration of $ 161.8 million, cash dividend of $ 4.0 million, cash settlement of stock options of $ 2.0 million and 5,808,925 shares of the Company’s Common Stock, the fair value of which was determined to be $ 36.7 million based on the closing price of the Company’s shares on the acquisition date. The acquisition was accounted for as a business combination using the acquisition method with Gran Tierra being the acquirer, whereby the assets acquired and liabilities assumed were recognized at their fair values as at the i3 Energy acquisition date, and the results of i3 Energy were included with those of Gran Tierra from that date. Fair value estimates were made based on significant unobservable (Level 3) inputs and based on the best information available at the time.

Determining the fair values of the assets and liabilities of i3 Energy and the consideration paid required significant judgment and certain assumptions to be made. The most significant fair value estimates related to the valuation of i3 Energy's proved and unproved oil and natural gas properties. The fair value of proved oil and natural gas properties acquired is based on cash flows associated with estimated acquired proved oil and natural gas reserves and the discount rate. Factors that impact these reserves cash flows include forecasted production, forecasted commodity prices, and forecasted operating, royalty and capital costs. Management is continuing to review and assess information to accurately determine the acquisition date fair value of the proved oil and natural gas properties and deferred tax assets and liabilities acquired.

Due to the timing of acquisition, management is continuing to review and assess information to accurately determine the acquisition date fair value of the proved oil and natural gas properties and deferred tax assets and liabilities acquired. As at March 31, 2025, there were no changes to initial measurement of fair value of the proved oil and natural gas properties and deferred tax assets and liabilities acquired.

Pro Forma Results (unaudited)

Pro forma for the three months ended March 31, 2024 are shown below, as if the i3 Energy acquisition had occurred on January 1, 2024. Pro forma results are not indicative of actual results or future performance:


	Three Months Ended March 31,
(Unaudited, thousands of U.S. Dollars)	2024
Oil, natural gas and NGL sales	$	197,412
Net loss	( 7,763 )

4. Segment and Geographic Reporting

The Company is primarily engaged in the exploration and production of oil and natural gas. The Company reports segmented information based on internal management reporting used b y our Chief Operational Decision Makers (“CODM”) , which are the Company’s Chief Executive Officer, Chief Financial Officer, Chief Operating Officer and Vice Presidents across various business functions. CODM allocates resources and assesses performance of each reportable segment based on segmented earnings. The Company determined three reportable segments based on the geographic organization: Colombia, Ecuador and Canada. The “Other” category represents the Company’s corporate activities.

The following tables present information on the Company’s reportable segments and other activities:

Credit Facility

In connection with the i3 Energy acquisition closing on October 31, 2024, the Company amended and restated the existing revolving credit facility agreement of i3 Energy Canada Ltd. with National Bank of Canada dated March 22, 2024. As a result of the amendment and restatement, among other things, the borrowing base was revised to C$ 100.0 million (US$ 69.5 million as of March 31, 2025) with available commitment of a C$ 50.0 million (US$ 34.8 million as of March 31, 2025) revolving credit facility comprised of C$ 35.0 million (US$ 24.3 million as of March 31, 2025) syndicated facility and C$ 15.0 million (US$ 10.4 million as of March 31, 2025) of operating facility. Subject to the next borrowing base redetermination which will occur on or before June 30, 2025, the revolving credit facility is available until October 31, 2025 with a repayment date of October 31, 2026, which may be extended by further periods of up to 364 days, subject to lender approval. The drawn down amounts under the revolving credit facility can either be in Canadian or U.S. dollars and bear interest rates equal to either the Canadian prime rate or U.S. Base Rate plus a margin ranging from 2.00 % to 4.00 % per annum or for CORRA loans and SOFR loans plus a margin ranging from 3.00 % to 5.00 % per annum. Undrawn amounts under the revolving credit facility bear standby fee ranging from 0.75 % to 1.25 % per annum. In each case, the margin or standby fee, as applicable is based on Net Debt to EBITDA ratio of Gran Tierra Canada Ltd. As of March 31, 2025, the credit facility was undrawn.

Senior Notes

During the three months ended March 31, 2025, the Company paid at maturity the remaining principal of $ 24.8 million of 6.25 % Senior Notes due in February 2025 for cash consideration of $ 25.6 million, including interest payable of $ 0.8 million.

The Company also purchased $ 1.8 million of 9.50 % Senior Notes for cash consideration of $ 1.7 million resulting in a $ 0.1 million loss on purchase, which included the write-off of deferred financing fees of $ 0.1 million.

At March 31, 2025, we had $ 24.2 million aggregate principal amount of 7.75 % Senior Notes due 2027, and $ 735.8 million aggregate principal amount of 9.50 % Senior Notes due 2029, outstanding.

Balance, March 31, 2025	6,596,009	1,013,509	1,059,425	1,125,461	8.85

As at March 31, 2025, the equity compensation award liability on the Company’s balance sheet included $ 1.0 million of current liability related to the Company’s outstanding stock options.

The fair value of each stock option award was estimated on the modification date using the Black-Scholes-Merton option-pricing model based on the assumptions noted in the following table:


Fair value of option modification			$ 0.00 - $ 6.11
Dividend yield (per share)			Nil
Expected volatility			43 % to 87 %
Risk-free interest rate			4.6 % to 5.1 %
Expected term			0.1 - 4.9 years
Expected forfeiture rate			0 % to 5 %

For the three months ended March 31, 2025 and 2024, there was $ 0.5 million of stock-based compensation recovery and $ 3.4 million of stock-based compensation expense, respectively.

As at March 31, 2025, there was $ 26.9 million (December 31, 2024 - $ 21.9 million) of unrecognized compensation costs related to unvested PSUs, RSUs 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, 2025, the Company paid out $ 7.2 million for PSUs vested on December 31, 2024 (three months ended March 31, 2024 - $ 10.4 million for PSUs vested on December 31, 2023).

During the three months ended March 31, 2025, the Company awarded 0.6 million RSU to employees pursuant to the existing 2007 Equity Incentive Plan. Under the 2007 Equity Incentive Plan, RSUs will vest one-third each year over a three-year period. Upon vesting, RSUs entitle the holder to receive either the underlying number of shares of the Company’s Common Stock or a cash payment equal to the value of the underlying shares of the Company’s Common Stock. The Company intends to settle RSUs outstanding as at March 31, 2025, in cash.

Net Income (Loss) per Share

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

Diluted net income or loss 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 shares of Common Stock 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 income or loss per share as their impact would be anti-dilutive.

Weighted Average Shares Outstanding

For the three months ended March 31, 2025 and 2024 all options were excluded from the diluted loss per share calculation as the options were anti-dilutive.

	$	157,577	$	—	$	—	$	157,577

During the three months ended March 31, 2025, the Company’s production was sold primarily to two major customers representing 65 % and 20 % of the total sales volumes, of which 60 % was sold in Colombia, 10 % in Ecuador and 30 % in Canada (three months ended March 31, 2024 - one major customer representing 100 % of the total sales volumes).

As at March 31, 2025, accounts receivable included $ 14.0 million of accrued sales revenue related to March 2025 production (December 31, 2024 - $ 13.4 million related to December 2024 production).

10. Taxes

The Company’s effective tax rate was negative 23 % for the three months ended March 31, 2025, compared to 100 % in the corresponding period of 2024.

Current income tax expense was $ 8.3 million for the three months ended March 31, 2025, compared to $ 3.9 million in the corresponding period of 2024, primarily due to an increase in taxable income in Ecuador, Canada and Colombia.

For the three months ended March 31, 2025, the deferred tax recovery of $ 4.7 million was mainly due to the use of a higher enacted tax rate on Colombian tax losses. These were partially offset by higher tax depreciation relative to accounting depreciation.

For the three months ended March 31, 2024, the deferred income tax expense was $ 13.5 million mainly as a result of tax depreciation being higher than accounting depreciation and the use of tax losses to offset taxable income in Colombia.

For the three months ended March 31, 2025, the difference between the effective tax rate of negative 23 % and the 40 % Colombian tax rate was primarily due to an increase in the non-deductible foreign translation adjustments, other permanent differences and valuation allowance. This was partially offset by an increase in the impact of foreign taxes.

For the three months ended March 31, 2024, the difference between the effective tax rate of 100 % and the 45 % Colombian tax rate was primarily due to an increase in the impact of foreign taxes, increase in the valuation allowance, non-deductible foreign translation adjustments, non-deductible stock-based compensation and other permanent differences.

11. Contingencies

Legal Proceedings

The Company has several lawsuits and claims pending. The outcome of the 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. The Company records costs as they are incurred or become probable and determinable.

Letters of Credit and Other Credit Support

At March 31, 2025, the Company had provided letters of credit and other credit support totaling $ 240.8 million (December 31, 2024 - $ 244.5 million) as security relating to work commitment guarantees in Colombia and Ecuador contained in exploration contracts, the Suroriente Block, and other capital or operating requirements as well as for transportation capacity in Canada.

12. 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, 2025, the Company’s financial instruments recognized on the balance sheet consist of cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, current portion of long-term debt, long-term debt 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, 2025, and December 31, 2024:


(Thousands of U.S. Dollars)	As at March 31, 2025		As at December 31, 2024
Level 1



Liabilities
6.25 % Senior Notes	$	—	$	24,133
7.75 % Senior Notes	21,422		21,451
9.50 % Senior Notes	651,421		688,262
	$	672,843	$	733,846
Level 2
Assets
Restricted cash and cash equivalents - long-term (1)	$	8,185	$	6,816
Commodity derivatives - current (2)	—		712
	$	8,185	$	7,528

Liabilities
Commodity derivatives - current (3)	$	1,290	$	—

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

(2) The current portion of commodity derivatives was included into other current assets on the Company’s condensed consolidated balance sheet.

(3) The current portion of commodity derivatives was included into accounts payable balance on the Company’s condensed consolidated balance sheet.

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

Restricted Cash and Cash Equivalents - Long-Term

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

Prepaid Equity Forward (“PEF”)

During the three months ended March 31, 2024, the Company settled all outstanding notional PEF shares and received net proceeds of $ 5.1 million resulting in a $ 0.3 million loss on settlement.

Senior Notes

Financial instruments recorded at amortized cost at March 31, 2025, were the Senior Notes (Note 7).

At March 31, 2025, the carrying amounts of the 7.75 % Senior Notes and 9.50 % Senior Notes were $ 23.9 million and $ 680.0 million, respectively, which represented the aggregate principal amounts less unamortized debt issuance costs and discounts, and the fair values were $ 21.4 million, and $ 651.4 million, respectively.

Derivative asset and derivative liability

The fair value of 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 whether such counterparty has the ability to meet its potential repayment obligations associated with the derivative transactions.

Commodity Price Risk

The Company may at times utilize 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. As at March 31, 2025, the Company had outstanding commodity price derivative positions in Canada and Colombia as follows:

• Oil, natural gas and NGL sales for the first quarter of 2025 increased by 8% to $170.5 million, compared to the first quarter of 2024, primarily due to increased sales volumes partially offset by lower oil prices. Oil, natural gas and NGL sales increased by 16% from $147.3 million in the prior quarter due to higher oil and gas prices, lower differentials, and increased sales volumes

• Operating expenses increased by 39% to $67.4 million when compared to the first quarter of 2024, primarily as a result of new Canadian operations and ramp-up of operations in Ecuador. Operating expenses increased by 11% from $60.8 million in the prior quarter as a result of three months of new Canadian operations opposed to two in the prior quarter

• Transportation expenses increased by 51% when compared to the first quarter of 2024 primarily due to 50% higher sales volumes from new Canadian operations and higher sales volumes transported in Ecuador during the period.

(1) Sales volumes represent production NAR adjusted for inventory changes.

(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 income (loss) 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 adjusted for depletion, depreciation and accretion (“DD&A”) expenses, interest expense and income tax expense or recovery. Adjusted EBITDA, as presented, is defined as EBITDA adjusted for non-cash lease expense, lease payments, foreign exchange gain or loss, stock-based compensation expense or recovery, transaction costs related to the acquisition of i3 Energy, other gain or loss and unrealized derivative instruments loss. 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, natural gas and NGL production NAR for the three months ended March 31, 2025, increased by 49% to 38,563 BOEPD compared to the corresponding period of 2024 due to the production from the Canadian operations acquired on October 31, 2024 and positive exploration well drilling results in Ecuador. Oil, natural gas and NGL production NAR increased by 14% compared to the prior quarter as a result of the full three months of operations in Canada and the successful drilling in Ecuador.

Royalties as a percentage of production for the three months ended March 31, 2025 decreased 3% and 1% compared to the corresponding period of 2024 and the prior quarter respectively, commensurate with the decrease in benchmark oil prices and lower royalties for Canadian operations.

The Midas Block includes the Acordionero field, the Suroriente Block includes the Cohembi field, and the Chaza Block includes the Costayaco and Moqueta fields. Ecuador includes the Charapa, Chanangue and Iguana Blocks. Canada includes several areas in the Western Canadian Sedimentary Basin with all production in Alberta, Canada.

AECO - For the three months ended March 31, 2025, AECO price increased 31% from the prior quarter. During the quarter, 52% of production in Canada was natural gas, comparable with the prior quarter.

Oil, natural gas and NGL sales for the three months ended March 31, 2025, increased by 8% to $170.5 million compared to the corresponding period of 2024 due 50% increase in sales volumes and lower differentials offset by 8% decrease in Brent price and lower sales volumes in Colombia. The increase in sales volumes during the current quarter was due to sales from new Canadian operations and higher sales volumes in Ecuador as a result of successful drilling results.

Compared to the prior quarter, oil, natural gas and NGL sales increased by 16%, primarily due to a 1% increase in Brent price, lower differentials, and an 18% increase in sales volumes as a result of full three months of operations in Canada compared to two months in prior quarter and higher sales volumes in Ecuador due to new exploration wells coming on production.

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, 2025, compared to the prior quarter and the corresponding periods of 2024:

Operating expense s for the three months ended March 31, 2025, increased by 39% to $67.4 million compared to the corresponding period of 2024 due to new Canadian operations and ramp-up of operations in Ecuador. On a per boe basis, operating expenses decreased by $1.24 to $19.18 compared to the corresponding period of 2024, primarily due to $2.76 per boe lower workover activities which were partially offset by $1.52 per boe higher lifting costs associated with Canadian operations.

Compared to the prior quarter, operating expenses increased by 11% from $60.8 million due to the full three months of new Canadian operations compared to two months in prior quarter, and decreased on a per boe basis by $0.85 from $20.03 primarily due to lower lifting costs associated with lower road maintenance costs in Colombia.

Transportation expenses

We have options to sell our oil through multiple pipelines and various trucking routes. Each option has varying effects on realized sales price and transportation expenses. The following table shows the percentage of oil, natural gas and NGL volumes we sold in Canada, Colombia and Ecuador using each option for the three months ended March 31, 2025 and 2024, and the prior quarter:


	Three Months Ended March 31,				Three Months Ended December 31,
	2025		2024		2024
Volume transported through pipeline	46	%	4	%	34	%
Volume sold at wellhead	25	%	52	%	32	%
Volume transported via truck to sales point	29	%	44	%	34	%
	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, 2025, increased by 51% to $6.9 million or $0.04 to $1.97 per boe, compared to the corresponding period of 2024, due to new Canadian operations and higher sales volumes transported in Ecuador during the current quarter.

Transportation expenses increased by 62% or $0.56 per boe from $4.3 million or $1.41 per boe in the prior quarter due to the higher sales volumes transported in Ecuador during the current quarter and the three full months of Canadian operations compared to two months in prior quarter.

DD&A expenses for the three months ended March 31, 2025, increased by 29% due to higher costs in the depletable base for Ecuador and new Canadian operations, compared to the corresponding period of 2024. On a per boe basis, DD&A expenses decreased by $3.10 due to higher sales volumes during the current quarter.

DD&A expenses increased by 14% from $63.4 million when compared to the prior quarter due to higher costs in the depletable base. On a per boe bases were comparable to prior quarter. On a per boe basis, DD&A expenses decreased by $0.34 due to higher sales volumes during the current quarter.

G&A Expenses, including Stock-Based Compensation	$	3.31	$	5.96	(44)	$	4.46

G&A expenses before stock-based compensation for the three months ended March 31, 2025, increased by 13% compared to the corresponding period of 2024, primarily due to addition of Canadian operations. On per boe basis, G&A expenses before stock-based compensation decreased by $1.08 due to higher sales volumes in the current quarter.

Compared to the prior quarter, G&A expenses before stock-based compensation increased by 19% or $0.10 per boe due to the three full months of operations in Canada during the current quarter compared to two months in the prior quarter.

G&A expenses after stock-based compensation for the three months ended March 31, 2025, decreased by 18% or $2.65 per boe, compared to the corresponding period of 2024, due to stock-based compensation recovery attributed to a lower share price during the current quarter.

Compared to the prior quarter, G&A expenses after stock-based compensation decreased by 14% or $1.15 per bbl for the same reason mentioned above.

Foreign Exchange Gains and Losses

For the three months ended March 31, 2025, we had a $3.8 million loss on foreign exchange compared to a $0.8 million gain on foreign exchange in the corresponding period of 2024, and a $0.5 million gain on foreign exchange in the prior quarter. Accounts payable, taxes receivable and payable and deferred income taxes 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, 2025 and 2024:

Income Tax Expense


	Three Months Ended March 31,
(Thousands of U.S. Dollars)	2025			2024
Income before income tax	$	(15,727)		$	17,317

Current income tax expense	$	8,265		$	3,916
Deferred income tax (recovery) expense	(4,712)			13,479
Income tax expense	$	3,553		$	17,395

Effective tax rate	(23)		%	100		%

Current income tax expense was $8.3 million for the three months ended March 31, 2025, compared to $3.9 million in the corresponding period of 2024, primarily due to an increase in taxable income in Ecuador, Canada and Colombia.

The deferred income tax for the three months ended March 31, 2025, was a recovery of $4.7 million mainly due to the use of a higher enacted tax rate on Colombia tax losses. These were partially offset by higher tax depreciation relative to accounting depreciation.

The deferred income tax expense for the three months ended March 31, 2024, was $13.5 million, primarily as a result of tax depreciation being higher than accounting depreciation and the use of tax losses to offset taxable income in Colombia.

For the three months ended March 31, 2025, the difference between the effective tax rate of negative 23% and the 40% Colombian tax rate was primarily due to an increase in the non-deductible foreign translation adjustments, other permanent differences and valuation allowance. This was partially offset by an increase in the impact of foreign taxes.

For the three months ended March 31, 2024, the difference between the effective tax rate of 100% and the 45% Colombian tax rate was primarily due to an increase in the impact of foreign taxes, increase in the valuation allowance, non-deductible stock-based compensation and other permanent differences.

We believe that our capital resources, including cash on hand, cash generated from operations and available borrowings under our credit facilities, 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, including for the re-purchase of common stock or the repayment of debt in the future. 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 to be located in basins or countries beyond our current operations, involve joint ventures, or be sizable compared to our current assets and operations.

In connection with the i3 Energy acquisition closing on October 31, 2024, we amended and restated the existing revolving credit facility agreement of i3 Energy Canada Ltd. with National Bank of Canada dated March 22, 2024. As a result of the amendment and restatement, among other things, the borrowing base was revised to C$100.0 million (US$69.5 million) with available commitment of a C$50.0 million (US$34.8 million) revolving credit facility comprised of C$35.0 million (US$24.3 million) syndicated facility and C$15.0 million (US$10.4 million) of operating facility. Subject to the next borrowing base redetermination which will occur on or before June 30, 2025, the revolving credit facility is available until October 31, 2025 with a repayment date of October 31, 2026, which may be extended by further periods of up to 364 days, subject to lender approval. The drawn down amounts under the revolving credit facility can either be in Canadian or U.S. dollars and bear interest rates equal to either the Canadian prime rate or U.S. Base Rate plus a margin ranging from 2.00% to 4.00% per annum or for CORRA loans and SOFR loans plus a margin ranging from 3.00% to 5.00% per annum. Undrawn amounts under the revolving credit facility bear standby fee ranging from 0.75% to 1.25% per annum. In each case, the margin or standby fee, as applicable is based on Net Debt to EBITDA ratio of Gran Tierra Canada Ltd. As of March 31, 2025, the credit facility remained undrawn.

Subsequent to March 31, 2025, we, through its wholly owned subsidiary, Gran Tierra Energy Colombia GmbH, a Swiss limited liability company, entered in to a US$75 million reserve-based lending facility. Any loans incurred under the new facility will mature on April 16, 2028 and will bear interest at a rate per annum equal to, at our option, either (a) a customary base rate (subject to a floor of 1.00%) plus an applicable margin of 4.50% or (b) a term SOFR reference rate plus an applicable margin of 4.50%. Interest on base rate borrowings is payable quarterly in arrears and interest on term SOFR borrowings accrues in respect of interest periods of three or six months, at the election of the Company, and is payable on the last day of such interest period.

At March 31, 2025, we had $24.2 million aggregate principal amount of 7.75% Senior Notes due 2027, and $735.8 million aggregate principal amount of 9.50% Senior Notes due 2029, outstanding.

During the three months ended March 31, 2025, we paid at maturity the remaining principal of $24.8 million of 6.25% Senior Notes due in February 2025 for cash consideration of $25.6 million, including interest payable of $0.8 million.

During the three months ended March 31, 2025, we re-purchased 453,050 shares under the 2024 Program at a weighted average price of $5.33 per share (three months ended March 31, 2024 - 886,666 shares under the 2023 program at a weighted average price of $5.58). Under the 2024 Program, we were able to re-purchase at prevailing market prices up to 3,545,872 shares of Common Stock, representing approximately 10% of the public float as of October 31, 2024. We cancelled 487,948 held as treasury shares as at December 31, 2024 and cancelled 443,050 shares re-purchased during the three months ended March 31, 2025, respectively. During the period from November 6, 2024 to April 29, 2025, we have re-purchased 1,140,752 shares under the 2024 Program.

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 transactions 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, 2025, funds flow from operations decreased by 26% compared to the corresponding period of 2024, due to a decrease in Brent price, higher operating

expenses, higher interest expense and higher current income tax expense partially offset by lower quality and transportation discounts and higher sales volumes.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are disclosed in Item 7 of our 2024 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, natural gas and NGL prices which 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 Brent or Edmonton Light pricing and for gas at AECO pricing and adjusted for quality.

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 81% of our revenues are related to the U.S. dollar price of Brent with the remainder related to Canadian dollar price of WTI oil or AECO gas. In Colombia and Ecuador, 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 all locations are in local currency. In Canada, we receive 100% of our revenue in Canadian dollar and majority of our capital and operating expenditures are in Canadian dollars or are based on Canadian dollar prices.

Additionally, foreign exchange gains and losses result primarily from the fluctuation of the U.S. dollar to the Colombian peso due to our accounts payable, taxes receivable and payable and deferred tax assets and liabilities in Colombia are denominated in the local currency of the Colombian foreign operations which are our monetary assets. As a result, a foreign exchange gain or loss must be calculated on conversion to the U.S. dollar reporting 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 revolving credit facility, which bears floating rates of interest. As of March 31, 2025 the revolving credit facility remained undrawn.

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, 2025.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2025, 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 11 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, 2024, 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, 2024. These risk factors could materially affect our business, financial condition and results of operations. The unprecedented nature of ongoing conflicts in several parts of the world, along with 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.
