 **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 and financial condition and those statements preceded by, followed by or that otherwise include the words "believe", "expect", "anticipate", "intend", "estimate", "project", "target", "goal", "plan", "budget", "objective", "should", "outlook" 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 ability to realize the anticipated benefits and operating synergies expected from the acquisition of i3 Energy Plc ("i3Energy"); certain of our operations are located in South America and the Company is pursuing activities in other international jurisdictions, including Azerbaijan, 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; global and regional changes in the demand, supply, prices, differentials or other market conditions affecting oil and natural gas, including inflation and changes resulting from actual or anticipated tariffs and trade policies, global health crises, geopolitical events, including the ongoing conflicts in Ukraine, the Middle East and Venezuela, or from the imposition or lifting of crude oil production quotas or other actions that might be imposed by OPEC, 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 prolonged 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 predict 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 our business plan, which may include acquisitions and realize expected benefits from current or future initiatives; such as the expected effectiveness of the exploration and development production sharing agreement ("EDPSA") in Azerbaijan and the timing and execution of the related exploration program; 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 access debt or equity capital markets from time to time to raise additional capital, increase liquidity, fund acquisitions or refinance debt; our ability to comply with financial covenants in our indentures and make borrowings under our 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 2025 Annual Report on Form 10-K (the "2025 Annual Report on Form 10-K"). This information included herein is given as of the filing date of this Quarterly Report on Form 10-Q with the Securities and Exchange Commission ("SEC") and, except as otherwise required by the 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.*

In July 2025, FASB issued ASU 2025-05 "Financial Instruments—Credit Losses: Amendments to the Measurement of Credit Losses on Certain Financial Assets". This ASU provides a practical expedient for estimating expected credit losses on certain short-term receivables and contract assets arising from revenue transactions within the scope of ASC 606. Under the practical expedient, all entities may elect to assume that current conditions as of the balance sheet date would not change for the remaining life of the asset when developing reasonable and supportable forecasts. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2025, early adoption is permitted for both interim and annual reporting periods. The Company adopted this ASU effective January 1, 2026. The implementation of this update did not have a material impact on its balance sheet, statement of operations or financial statements disclosures.

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, 2026, 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, 2026 and 2025, all options were excluded from the diluted loss per share calculation as the options were anti-dilutive.

During the three months ended March 31, 2026, the Company's production was sold primarily to one major customer, representing 74% of the total Company's sales volumes (three months ended March 31, 2025 - one major customer, representing 65% of total Company's sales volumes), reported in each of the reportable segments.

As at March 31, 2026, accounts receivable included $27.6 million of accrued sales revenue related to March 2026 production (December 31, 2025 - $14.8 million related to December 2025 production).

**10. Taxes**

The Company's effective tax rate was 18% for the three months ended March 31, 2026, compared to a negative 23% in the corresponding period of 2025.

Current income tax expense was $5.9 million for the three months ended March 31, 2026, compared to $8.3 million in the corresponding period of 2025, primarily due to lower taxable income.

For the three months ended March 31, 2026, the Company recognized a deferred tax recovery of $32.4 million, primarily attributable to an increase in deductible temporary differences arising from tax losses generated during the period and accruals. This recovery was partially offset by temporary differences related to accelerated tax depreciation in excess of accounting depreciation.

For the three months ended March 31, 2025, the deferred income 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, 2026, the difference between the effective tax rate of 18% and the 21% statutory tax rate was primarily due to an increase in the non-deductible foreign translation adjustments and other permanent differences. This was partially offset by an increase in the impact of foreign taxes.

For the three months ended March 31, 2025, the difference between the effective tax rate of negative 23% and the 21% statutory 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.

**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, 2026, the Company had provided letters of credit and other credit support totaling $222.5 million, of which $61.3 million was related to capital commitments in the Suroriente Block and $0.5 million related to transportation capacity in Canada with the remaining as security relating to work commitment guarantees in Colombia and Ecuador contained in exploration contracts, other capital or operating requirements (December 31, 2025 - $209.0 million).

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 - Inputs representing quoted market prices in active markets for identical assets and liabilities

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 - Unobservable inputs for assets and liabilities

At March 31, 2026, the Company's financial instruments recognized on the balance sheet consist of cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, derivatives, 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, 2026, and December 31, 2025:

---

| | | |
|:---|:---|:---|
| **(Thousands of U.S. Dollars)** | **As at March 31, 2026** | **As at December 31, 2025** |
| **Level 1** | | |
| **Liabilities** | | |
| 7.75% Senior Notes | $**20329** | $19784 |
| 9.50% Senior Notes | **80253** | 505020 |
| 9.75% Senior Notes | **435958** |  |
|  | $**536540** | $524804 |
| **Level 2** |  |  |
| **Assets** |  |  |
| Restricted cash and cash equivalents - long-term <sup>(1)</sup> | $**10100** | $9735 |
| Foreign currency derivatives - current | **444** | 10147 |
|  | $**10544** | $19882 |
| **Liabilities** |  |  |
| Commodity derivatives - current | $**76891** | $— |
|  | $**76891** | $— |

---

<sup>(1)</sup> 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.

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.

*Senior Notes* 

Financial instruments recorded at amortized cost at March 31, 2026, were the Senior Notes (Note 6).

------

At March 31, 2026, the carrying amounts of the 7.75% Senior Notes, 9.50% Senior Notes and 9.75% Senior Notes were $24.0 million, $83.5 million and $466.2 million, respectively, which represented the aggregate principal amounts less unamortized debt issuance costs and discounts, and the fair values were $20.3 million, $80.3 million and $436.0 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, 2026, the Company had outstanding commodity price derivative positions in Canada and Colombia as follows:

**Item 2. *Management's Discussion and Analysis of Financial Condition and Results of Operations***

*The following discussion of our financial condition and results of operations should be read in conjunction with the "Financial Statements" as set out in Part I, Item 1 of this Quarterly Report on Form 10-Q, as well as "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the "Financial Statements and Supplementary Data" included in Part II, Items 7 and 8, respectively, of our 2025 Annual Report on Form 10-K. Please see the cautionary language at the beginning of this Quarterly Report on Form 10-Q regarding the identification of and risks relating to forward-looking statements and the risk factors described in Part II, Item 1A "Risk Factors" of this Quarterly Report on Form 10-Q, as well as Part I, Item 1A "Risk Factors" in our 2025 Annual Report on Form 10-K.*

**Financial and Operational Highlights** 

**Key Highlights for the first quarter of 2026**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net loss for the first quarter of 2026 was $119.2 million or $3.38 per share basic and diluted, compared to a net loss of $19.3 million or $0.54 per share basic and diluted for the first quarter of 2025 and a net loss of $141.1 million for the prior quarter. The following non-cash items were the main contributors to net loss for the first quarter of 2026: $77.3 million unrealized mark-to-market hedging loss, $19.7 million stock-based compensation remeasurement, $11.3 million amortization of deferred financing fees and $4.5 million oil prepayment interest

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss before income taxes for the first quarter of 2026 was $145.8 million, compared to loss before income taxes of $15.7 million for the first quarter of 2025 and loss before income taxes of $177.8 million for the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Brent oil price averaged $78.38 per bbl during the quarter, an increase of 5% from the comparative period of 2025, and a 24% increase from the prior quarter. Castilla, Vasconia and Oriente differentials averaged $9.67, $5.91 and $8.17 per bbl during the quarter, an increase of 81%, 160% and 7% from the comparable period of 2025, and an increase of 49%, 73% for Castilla and Vasconia differentials and 3% decrease for Oriente differential from the prior quarter, respectively

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Adjusted EBITDA<sup>(2)</sup> was $73.9 million for the first quarter of 2026, a decrease from $85.2 million in the first quarter of 2025, and an increase from $52.5 million in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Funds flow from operations<sup>(2)</sup> decreased to $42.8 million compared to $55.3 million in the first quarter of 2025, and increased from $26.8 million in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** NAR production for the first quarter of 2026 decreased by 2% to 37,741 BOEPD, compared to 38,563 BOEPD in the first quarter of 2025, and decreased by 4% from 39,464 BOEPD in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** NAR Sales volumes for the first quarter of 2026 increased by 3% to 40,267 BOEPD, compared to 39,024 BOEPD in the first quarter of 2025 and increased by 12% from 35,984 BOEPD in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Oil, natural gas and NGL sales for the first quarter of 2026 increased by 2% to $172.1 million, compared to the first quarter of 2025, due to higher sales volumes driven by selling production from the newly acquired Perico Block in Ecuador and increase in Brent price, offset by higher quality and transportation discounts in Colombia. Higher quality and transportation discounts incurred due to using alternative transportation route associated with Putumayo production which was significantly more expensive and resulted in approximately $4.1 million for the current quarter. Oil, natural gas and NGL sales increased by 32% from $129.9 million in the prior quarter due to higher oil prices, and increase in sales volumes, partially offset by higher differentials. During the first quarter, we had two liftings in Ecuador compared to one in the prior quarter. The sales price in Ecuador is the average Brent price less discounts for the month prior to lifting (M-1). During the current quarter, we sold our January 2026 production in Ecuador at the average Brent price of December 2025 and March production at the average Brent price of February 2026

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Operating expenses decreased by 1% or $0.85 per boe to $66.1 million or $18.25 per boe when compared to the first quarter of 2025, due to lower workover activities, lower power generation and field personnel costs associated with head-count optimization partially offset by inventory fluctuations due to the sale of oil inventory accumulated at the end of the previous quarter. Operating expenses increased by 16% or by $0.98 per boe from $57.2 million or $17.27 per boe in the prior quarter primarily a result of inventory fluctuations due to the sale of oil inventory accumulated at the end of the previous quarter partially offset by lower workover activities and lower operating costs across various categories

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Transportation expenses increased by 17% when compared to the first quarter of 2025 and increased by 44% compared to the prior quarter primarily due to higher sales volumes transported in Ecuador during the current quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross profit increased to $36.7 million compared to $28.1 million in first quarter of 2025 and $0.9 million in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Operating netback<sup>(2)</sup> was $100.6 million compared to $96.5 million in the first quarter of 2025 and $69.1 million in the prior quarter

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Quality and transportation discounts per boe in South America increased for the first quarter of 2026 to $19.04 compared to $11.58 in the first quarter of 2025 and $12.30 in the prior quarter, due to higher differentials and transportation discounts. Higher transportation discounts were incurred due to utilizing alternative transportation route associated with Putumayo production in Colombia which was significantly more expensive and resulted in approximately $4.1 million for the current quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quality and transportation discounts for oil per boe in Canada increased for the first quarter of 2026 to $9.64 compared to $7.48 in the first quarter of 2025 due to higher pipeline tariffs related to new wells drilled and decreased from $10.35 in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** General and administrative ("G&A") expenses before stock-based compensation for the first quarter of 2026 increased to $15.1 million compared to $11.9 million in the first quarter of 2025 due to higher consulting costs attributable to optimization projects and decreased from $16.8 million in the prior quarter due to headcount optimization measures implemented during the current quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Capital expenditures for the first quarter of 2026 were $45.4 million compared to $94.7 million in the first quarter of 2025 and $53.0 million in the prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** During the first quarter, we entered into a strategic partnership with Ecopetrol S.A. to earn, subject to regulatory approvals and conditions precedent, a 49% WI in the Tisquirama Block in Colombia

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** During the first quarter of 2026, we completed the disposition of our entire working interest and associated title rights in the Simonette Montney area in Canada

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** During the first quarter of 2026 we entered into an exploration, development and production sharing agreement with the State Oil Company of the Republic of Azerbaijan, for the onshore Guba–Khazaryani region in Azerbaijan, expanding our international exploration portfolio

<sup>(1)</sup> Sales volumes represent production NAR adjusted for inventory changes.

Gross profit is derived from oil, gas and NGL sales, less operating and transportation expenses, and depletion and accretion related to producing assets. Gross profit does not include depreciation of administrative assets, asset impairment, general and administrative expenses, interest, taxes or other non-operating items.

Operating netback, EBITDA, adjusted 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 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 gross profit adjusted for depletion and accretion related to producing assets. 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 gross profit to operating netback is provided in the table below.

***Oil, natural gas and NGL production NAR*** for the three months ended March 31, 2026, decreased by 2% to 37,741 BOEPD compared to the corresponding period of 2025 due to lower production in Acordionero field in Colombia and the sale of Simonette area in Canada, partially offset by higher than anticipated production results from Conejo-1 well in Charapa Block and additional production from Perico Block in Ecuador acquired in December 2025. Oil, natural gas and NGL production NAR decreased by 4% compared to the prior quarter for the same reason mentioned above.

***Royalties*** as a percentage of production for the three months ended March 31, 2026 were comparable to the corresponding period of 2025. Royalties as a percentage of production increased 2% compared to the prior quarter commensurate with the increase in benchmark oil prices and the price sensitive royalty regime in Colombia, Ecuador, and Canada.

**Brent *-*** For the three months ended March 31, 2026, Brent increased 5% from the corresponding period of 2025 and increased 24% from the prior quarter. For the three months ended March 31, 2026, Castilla, Vasconia and Oriente differentials per boe increased to $9.67, $5.91 and $8.17 compared to $5.34, $2.27 and $7.65, respectively, in the corresponding period of 2025. Additionally, the realized price for South America was effected by higher transportation discounts. Higher transportation discounts were incurred due to utilizing alternative transportation route associated with Putumayo production in Colombia which was significantly more expensive and resulted in approximately $4.1 million for the current quarter.

During the three months ended March 31, 2026, 100% of sales from South America was priced against Brent.

**NGLs** - For the three months ended March 31, 2026, the weighted average NGL price received was 10% of WTI compared to 14% percent of WTI in the comparable period of 2025 and 22% percent of WTI in the prior quarter. During the first quarter of 2026, 26% of production in Canada were NGLs, compared to 27% from the comparable period of 2025 and 24% in the prior quarter.

**AECO** - For the three months ended March 31, 2026, AECO price decreased 7% and 9% from the comparable period of 2025 and from prior quarter, respectively. During the first quarter of 2026, 49% of production in Canada was natural gas, compared to 52% from the comparable period of 2025 and 50% in the prior quarter.

***Oil, natural gas and NGL sales*** for the three months ended March 31, 2026, increased by 2% to $172.1 million compared to the corresponding period of 2025 due to 3% higher sales volumes driven by selling production from newly acquired Perico Block in Ecuador and 5% increase in Brent price, offset by higher quality and transportation discounts in Colombia. Higher quality and transportation discounts incurred due to using alternative transportation route associated with Putumayo production which was significantly more expensive and resulted in approximately $4.1 million for the current quarter.

------

Compared to the prior quarter, oil, natural gas and NGL sales increased by 32%, primarily due to a 24% increase in Brent price, and a 12% increase in sales volumes as a result of higher sales volumes in Ecuador partially offset by higher differentials. During the first quarter, we had two liftings in Ecuador compared to one in prior quarter. The sales price in Ecuador is the average Brent price less discounts for the month prior to lifting (M-1). During the three months ended March 31, 2026, we sold our January 2026 production for the average Brent price of December 2025 and the March 2026 production at the average Brent price of February 2026.

***Operating expense*s** for the three months ended March 31, 2026, decreased by 1% to $66.1 million compared to the corresponding period of 2025 due to lower workover activities, lower power generation and field personnel costs associated with head count optimization partially offset by higher inventory fluctuations due to the sale of oil inventory accumulated at the end of the previous quarter.

On a per boe basis, operating expenses decreased by $0.85 to $18.25 compared to the corresponding period of 2025, primarily due to $1.14 per boe lower workover activities which were partially offset by $0.21 per boe higher lifting costs associated with inventory fluctuations.

Compared to the prior quarter, operating expenses increased by 16% from $57.2 million or by $0.98 from $17.27 on a per boe basis primarily a result of inventory fluctuations due to the sale of oil inventory accumulated at the end of the previous quarter partially offset by lower workover activities and lower operating costs across various categories.

***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, 2026 and 2025, and the prior quarter:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** | **Three Months Ended December 31,** |
| | **2026** | **2025** | **2025** |
| Volume transported through pipeline | **54%** | 46% | 46% |
| Volume sold at wellhead | **24%** | 25% | 28% |
| Volume transported via truck to sales point | **22%** | 29% | 26% |
|  | **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, 2026, increased by 17% to $5.3 million or $0.16 to $1.46 per boe, compared to the corresponding period of 2025, due to higher sales volumes transported in Ecuador during the current quarter.

Transportation expenses increased by 44% or $0.35 per boe from $3.7 million or $1.11 per boe in the prior quarter for the same reason mentioned above.

---

***DD&A expenses*** for the three months ended March 31, 2026, decreased by 3% or by $1.28 on a per boe basis, due to lower costs in the depletable base for Canadian operations as a result of Simonette field disposition and higher proved reserves in Ecuador, compared to the corresponding period of 2025.

DD&A expenses decreased by 4% from $72.5 million or by $2.63 on a per boe basis when compared to the prior quarter for the same reason mentioned above.

**Asset Impairment**

For the three months ended March 31, 2026 and 2025, we had no ceiling test impairment losses. We used a 12-month unweighted average of the first-day-of the month prices prior to the ending date of the period ended March 31, 2026 as follows: Brent Crude $67.58 per boe, Edmonton Light Crude of C$83.04 per boe, Alberta AECO spot price of C$1.99 per MMBtu Edmonton Propane C$28.38 per boe, Edmonton Butane C$36.04 per boe and Edmonton Condensate C$85.94 and for the period ended three months ended March 31, 2025 Brent Crude of $78.90 per boe, Edmonton Light Crude of C$98.11 per boe, Alberta AECO spot price of C$1.51 per MMBtu Edmonton Propane C$32.53 per boe, Edmonton Butane C$48.81 per boe and Edmonton Condensate C$101.71.

***G&A expenses before stock-based compensation*** for the three months ended March 31, 2026, increased by 27% to $15.1 million or by $0.78 to $4.18 per boe compared to the corresponding period of 2025, primarily due to higher consulting costs attributable to optimization projects.

Compared to the prior quarter, G&A expenses before stock-based compensation decreased by 10% or $0.90 per boe due to headcount optimization and higher sales volumes.

***G&A expenses after stock-based compensation*** for the three months ended March 31, 2026, increased by 205% or $6.36 per boe, compared to the corresponding period of 2025, due to higher stock-based compensation cost attributed to a higher share price during the current quarter.

Compared to the prior quarter, G&A expenses after stock-based compensation increased by 75% or $3.61 per boe for the same reason mentioned above.

**Severance Expenses**

For the three months ended March 31, 2026, severance expenses were $2.5 million, compared to nil for the corresponding period of 2025 and the prior quarter, respectively due to headcount optimization.

**Foreign Exchange Gains and Losses**

For the three months ended March 31, 2026, we had a $1.4 million loss on foreign exchange compared to a $3.8 million loss on foreign exchange in the corresponding period of 2025, and a $0.9 million loss 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.

| Income tax (recovery) expense | $**(26595)** | $3553 |

---

Current income tax expense was $5.9 million for the three months ended March 31, 2026, compared to $8.3 million in the corresponding period of 2025, primarily due to lower taxable income.

The deferred tax for the three months ended March 31, 2026, was a recovery of $32.4 million mainly due to an increase in deductible temporary differences arising from tax losses generated during the period and accruals. These were partially offset by higher tax depreciation relative to accounting depreciation.

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.

For the three months ended March 31, 2026, the difference between the effective tax rate of 18% and the 21% statutory tax rate was primarily due to an increase in the non-deductible foreign translation adjustments and other permanent differences. This was partially offset by an increase in the impact of foreign taxes.

For the three months ended March 31, 2025, the difference between the effective tax rate of negative 23% and the 21% statutory 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.

We believe that our capital resources, including cash on hand and cash generated from operations 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.

***Senior Notes***

During the three months ended March 31, 2026, we issued $503.6 million in aggregate principal amount of its 9.75% Senior Secured Amortizing Notes due 2031 (the "9.75% Senior Notes"), and paid $125.0 million in cash consideration in exchange for $628.7 million aggregate principal amount of its 9.50% Senior Secured Amortizing Notes due 2029 (the "9.50% Senior Notes"). The exchange was accounted for as debt modification.

The principal amount of 9.75% Senior Notes is to be repaid as follows: (i) October 15, 2029 - 15% of the principal amount; (ii) October 15, 2030 - 15% of the principal amount; (iii) April 15, 2031 - the remainder of the principal amount. We are required to complete mandatory redemption of $30.0 million aggregate principal amount of 9.75% Senior Notes less any re-purchases in the open market during the year ended December 31, 2026.

At any time, prior to April 15, 2028, we may redeem up to 0.35 of the aggregate principal amount of 9.75% Senior Notes at a redemption price equal to 1.0975 of the principal amount. Additionally, we may redeem all or a portion of the 9.75% Senior Notes on or after 2028 at the following redemption prices: 2028 - 1.04875; 2029 - 1.02438; 2030 and thereafter - 1.

***Credit Facility***

As at March 31, 2026, we, through our wholly owned subsidiary Gran Tierra Canada Ltd., had a revolving credit facility with National Bank of Canada with a borrowing base of C$100.0 million (US$71.9 million) and the available commitment of a C$75.0 million (US$54.0 million) revolving credit facility comprised of C$60.0 million (US$43.2 million) syndicated facility and C$15.0 million (US$10.8 million) of operating facility. 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. The revolving credit facility matures on October 30, 2027. As of March 31, 2026, the revolving credit facility remained undrawn.

***Prepayment agreements***

During the three months ended March 31, 2026, we amended our existing prepayment agreement with Trafigura, entering into a new oil prepayment agreement that covers both our Ecuadorian and Colombian oil production. The amended agreement provides for a total prepayments of up to $350.0 million, including $325.0 million available immediately and additional $25.0 million available at Trafigura's sole discretion. The term of the amended prepayment agreement is 48 months.

Amounts drawn on this prepayment agreement are to be repaid through future oil deliveries. Shortfalls in crude oil deliveries in any given repayment period can be delivered during the next repayment period within three calendar months or paid in cash thereafter. Amounts under the prepayment facility are subject to interest based on SOFR risk-free rate plus a margin of 4.45% per annum. Under the terms of the prepayment agreement, we can repay the outstanding balance of the advance payment at any time without penalty. We were granted a six-month grace period for repayment of the principal amount drawn under the prepayment agreement with first re-payment starting April 2026.

Pursuant to the amended and restated prepayment agreement, proceeds from the new advance are required to be used exclusively to finance the repurchase or exchange of Senior Notes and to pay fees and expenses associated with the amended agreement.

We are required to maintain compliance with the following financial covenants related to amounts drawn under the prepayment agreement semi-annually, calculated on March 31 and September 30 of each year:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Asset Coverage Ratio of at least 150%, calculated using the net present value of the consolidated future cash flows of certain wholly owned subsidiaries of the Company that sell crude oil, projected through the final maturity date and discounted at 10% over the outstanding principal and the interest payable amount on the prepayment agreement at each reporting period. The net present value of the consolidated future cash flows of the Company is required to be based on 90% of the prevailing ICE Brent forward strip.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.Debt Service Coverage Ratio of at least 200%, calculated using the estimated crude oil to be delivered by the Company from any relevant time up to the final maturity date based on 80% of the prevailing ICE Brent forward strip and adjusted for quality differential and transportation discount over the outstanding principal amount under the prepayment agreement.

<sup>(1)</sup> Adjusted EBITDA and funds flow from operations are non-GAAP measures which do not have any standardized meaning prescribed under GAAP. Refer to note 2 "Non-GAAP measures" in "Financial and Operational Highlights" 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 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, 2026, funds flow from operations decreased by 23% compared to the corresponding period of 2025, due to higher quality and transportation discounts, higher interest expense partially offset by an increase in Brent price, higher sales volumes, lower operating expenses, and lower current income tax expense.

**Critical Accounting Policies and Estimates**

Our critical accounting policies and estimates are disclosed in Item 7 of our 2025 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. As at March 31, 2026, 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 83% 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 our operating costs, income taxes, VAT, 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.

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 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 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 revolving Canadian credit facility which bears floating rates of interest. As of March 31, 2026, 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, 2026.

**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, 2026, 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, 2025, 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, 2025. 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.

**Item 2. *Unregistered Sales of Equity Securities and Use of Proceeds***

**Issuer Purchases of Equity Securities**

| **Total** | **—** | $**—** | **—** | **2925720** |

<sup>(1)</sup> On November 3, 2025, we implemented a share re-purchase program (the "2025 Program") through the facilities of the TSX, the NYSE American or alternative programs in Canada or the United States commencing November 6, 2025 and ending on November 5, 2026. Under the 2025 Program, we are able to purchase at prevailing market prices up to 2,925,720 shares of Common Stock, representing approximately 10% of the public float as of October 31, 2025.

**Item 5. *Other Information***

During the three months ended March 31, 2026, no director or Section 16 officer adopted or terminated any Rule 10b5-1 trading arrangements or non-Rule 10b5-1 trading arrangements (in each case, as defined in Item 408(a) of Regulation S-K).

As disclosed in a Form 8-K filed by the Company on March 17, 2026, the Company's Audit Committee has been conducting an independent investigation into an anonymous complaint.

Consistent with its charter, the Audit Committee takes seriously its responsibility to investigate matters within the scope of its duties. As such, the Audit Committee investigated the allegations in the complaint that it believed were in the scope of its responsibility. The Audit Committee took various steps to ensure that it would meet its fiduciary duties of loyalty, care and oversight in conducting the investigation. Such steps included seeking legal advice from external legal counsel and engaging throughout the entirety of the investigatory process independent legal counsel who conducted investigatory procedures. The engagements concluded under the direction and oversight of the Audit Committee. Following the engagements and multiple meetings and deliberations of the Audit Committee, the Audit Committee concluded that, subject to undertaking certain process improvements, all of which have been satisfactorily implemented by the Company, its investigation is complete.
