On January 26, 2026, the Company entered into a commitment letter (the "Commitment Letter"), regarding a new oil prepayment agreement (the "New Prepayment Addendum") with respect to our Ecuadorian and Colombian production, subject to satisfaction of the conditions set forth therein, including the completion of our upcoming Exchange Offer (as defined below). The New Prepayment Addendum (x) provide for a new advance (the "New Prepayment Advance") to Gran Tierra Energy Colombia GmbH, a limited liability company incorporated under the laws of Switzerland ("GTEC"), and Gran Tierra Operations Colombia GmbH, a limited liability company incorporated under the laws of Switzerland ("GTOC") in order to satisfy the Cash Consideration (as defined in the press release attached hereto as Exhibit 99.2) under the Exchange Offer, and (y) provide for a new uncommitted advance (the "New Prepayment Accordion"), in each case subject to customary conditions precedent, and (iii) provide for liens over the Colombian assets of GTEC and GTOC to secure a certain maximum amount of obligations under the New Prepayment Addendum (the "Financing Condition"). We will enter into the New Prepayment Addendum on or prior to the consummation of the Exchange Offer.

As contemplated by the Commitment Letter, on or prior to the consummation of the Exchange Offer we will enter into one or more new purchase and sale agreements to provide for the sale by GTEC and GTOC of crude oil produced from GTEC and GTOC's Colombian assets (the "New Purchase and Sale Agreement"). Amounts advanced under the New Prepayment Addendum will be satisfied through deliveries of crude oil by GTEC and GTOC in accordance with the New Purchase and Sale Agreement. The maturity date of the New Purchase and Sale Agreement is expected to be four years after the date of the existing Prepayment Addendum.

Outstanding advances under the New Prepayment Advance and the New Prepayment Accordion (if any) are expected to bear interest at a rate equal to term SOFR plus 5.00% per annum, calculated on the basis of a 360-day year. GTEC and GTOC are expected to pay (i) a commitment fee on the committed and available advances under the New Prepayment Addendum, payable quarterly in arrears and (ii) a structuring fee on the new commitments under the New Prepayment Addendum. The obligations of GTEC and GTOC under the New Prepayment Addendum are expected to be guaranteed by the Company and up to a certain amount of such obligations is expected to be secured by the Colombian assets of GTEC and GTOC, including liens on (i) our Colombian production and the exploration and production agreements, operation and maintenance agreements, and marketing agreements relating thereto, (ii) substantially all Colombian assets of GTEC and GTOC, and (iii) the Colombian commercial establishments (*establecimientos de comercio*) of GTEC and GTOC.

The New Prepayment Addendum is expected to include financial covenants requiring GTEC and GTOC to maintain (i) a minimum asset coverage ratio and (ii) a minimum debt service coverage ratio, tested on a semi-annual basis and upon certain other events. The New Prepayment Addendum is also expected to include various customary negative covenants, including restrictions on the ability of GTEC and GTOC to incur debt, grant liens, make dispositions, make distributions, engage in transactions with affiliates, or make investments.

The funds advanced under the New Prepayment Addendum are expected to be used to pay the Cash Consideration and satisfy the Financing Condition under the Exchange Offer. If the Exchange Offer is not consummated, we will not enter into the New Purchase and Sale Agreement and the New Prepayment Addendum.

In connection with the New Purchase and Sale Agreements and the New Prepayment Addendum, we expect to terminate our existing Colombian reserve-based lending facility and repay all outstanding borrowings thereunder substantially concurrently with the consummation of the Exchange Offer, and all security interests and guarantees granted thereunder will be released.

The information in this Item 7.01 is being furnished and shall not be deemed "filed" for the purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference into any filing by the Company under the Securities Act, or the Exchange Act, regardless of any general incorporation language contained in such filing.

***Exchange Offer and Consent Solicitation***

On January 29, 2026, the Company commenced a private offer to all Eligible Holders (as defined in the press release attached hereto as Exhibit 99.2) to exchange (the "Exchange Offer") any and all outstanding 9.500% Senior Notes due 2029 (the "Existing Notes") issued by the Company, for newly issued 9.500% Senior Secured Notes due 2031 (the "New Notes") to be issued by the Company, pursuant to the terms and subject to the conditions set forth in a confidential exchange offer memorandum and consent solicitation statement, dated January 29, 2026 (the "Exchange Offer Memorandum").

In conjunction with the Exchange Offer, the Company is conducting a solicitation (the "Solicitation") of consents (the "Consents") from Eligible Holders of Existing Notes to, among other things, eliminate from the indenture dated as of October 20, 2023, between the Company, as issuer, certain subsidiaries of the Company, as guarantors, and the trustee party thereto, under which the Existing Notes were issued (the "Existing Indenture"), substantially all of the restrictive covenants and events of default and related provisions under the Existing Indenture and to release the collateral securing the Existing Notes.

The Company's obligation to accept Existing Notes tendered pursuant to the Exchange Offer and Consents delivered pursuant to the Solicitation is subject to the satisfaction of certain conditions described in the Exchange Offer Memorandum, which include, (i) the valid receipt (and not valid revocation) of the Consents of Eligible Holders of Existing Notes that, in the aggregate, represent not less than 66 2/3% in aggregate principal amount of the Existing Notes outstanding to effect the Proposed Amendments (as defined in the press release attached hereto as Exhibit 99.2), (ii) the valid tender (and not validly withdrawal) of Existing Notes by Eligible Holders in the Exchange Offer that, in the aggregate, represent not less than 80% in aggregate principal amount of the Existing Notes outstanding prior to the Early Participation Deadline (as defined in the press release attached hereto as Exhibit 99.2) and (iii) the consummation of an incurrence of new indebtedness, on terms and subject to conditions satisfactory to the Company, that results in the receipt of net proceeds that are sufficient to pay the Cash Consideration.

The Exchange Offer and the Solicitation will expire at 5:00 p.m., New York City time, on February 26, 2026, unless extended or earlier terminated (such time and date, as the same may be extended or earlier terminated, the "Expiration Deadline"). However, Eligible Holders who validly tender and do not validly withdraw their Existing Notes at or prior to 5:00 p.m., New York City time, on February 10, 2026 (as the same may be extended or earlier terminated, the "Early Participation Deadline"), will be eligible to receive greater consideration for their Existing Notes than will be available for tenders made after the Early Participation Deadline but at or prior to the Expiration Deadline, all as more fully described in the attached press release and in the Exchange Offer Memorandum. Eligible Holders who validly tender and do not validly withdraw their Existing Notes at or prior to the Early Participation Deadline will receive their New Notes on a date promptly following the Early Participation Deadline, which date is expected to be February 17, 2026. All Eligible Holders who validly tender and do not validly withdraw their Existing Notes at or prior to the Expiration Deadline (as defined in the press release attached hereto as Exhibit 99.2) will receive their New Notes on a day that is promptly after the Expiration Deadline, which date is expected to be February 27, 2026.

The Exchange Offer and the Solicitation are being made solely pursuant to the conditions set forth in the Exchange Offer Memorandum in a private offering exempt from, or not subject to, registration under the Securities Act of 1933, as amended (the "Securities Act"), and are subject to certain conditions set forth in the Exchange Offer Memorandum, although the Company may waive any such conditions at any time.

Investors should carefully review the attached press release for further details regarding the Exchange Offer and the Solicitation. A copy of the Company's press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

This announcement does not constitute an offer to (i) buy or the solicitation of an offer to sell the Existing Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction or (ii) sell or the solicitation of an offer to buy the New Notes, nor shall there be any sale of the New Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. The Exchange Offer and the Solicitation are being made solely pursuant to the Exchange Offer Memorandum and only to such persons and in such jurisdictions as is permitted under applicable law.

**CALGARY, ALBERTA, January 29, 2026, Gran Tierra Energy Inc**. **("Gran Tierra" or the "Company") (NYSE American:GTE)(TSX:GTE)(LSE:GTE)** today provided an operational update. All dollar amounts are in United States dollars and all production volumes are on a working interest before royalties basis and are expressed in barrels of oil equivalent (**"boe"**) per day (**"boepd"**), unless otherwise stated.

2025 – the highest monthly production achieved in Company history.

· **Ecuador** 

&nbsp;&nbsp;&nbsp;&nbsp;o **Production**: During the fourth quarter of 2025, Gran Tierra
achieved a daily production rate of 10,000 bopd in Ecuador. Current production<sup>1</sup> rates are approximately 8,800 barrels of oil
per day ()"**bopd** ").

&nbsp;&nbsp;&nbsp;&nbsp;o **Fulfilled Ecuador Exploration Commitments:** All Ecuador exploration
commitments have been finalized, highlighted by successful discoveries at Conejo in the Hollín and Basal Tena sands, which together
delivered combined IP60 rates of approximately 3,238 bopd.

&nbsp;&nbsp;&nbsp;&nbsp;o **Conejo A-1 and A-2 Wells:** The two Conejo wells continue to
produce<sup>1</sup> roughly 2,700 barrels of oil per day. Both discoveries added drilling locations. IP60 production rates from A1 and
A2 are 1,921 and 1,317 bopd respectively.

&nbsp;&nbsp;&nbsp;&nbsp;o **Field Development Plans ("FDP")**: In the first
quarter of 2026, the Iguana FDP was approved. The Chanangue FDP received approval in the third quarter of 2025, while the Charapa and
Conejo FDPs were formally submitted in fourth quarter of 2025 and remain under review. In addition, the Perico and Espejo FDPs associated
with the previously announced acquisition, have been submitted and are currently undergoing the regulatory review process.

&nbsp;&nbsp;&nbsp;&nbsp;o **Perico and Iguana Field**: The Perico field has now been fully
integrated into our portfolio with optimizations being developed to capture synergies as we move into 2026 – these include projects
such as gas to power, waterflood initiation and operational optimizations.

&nbsp;&nbsp;&nbsp;&nbsp;o **Waterflood:** Gran Tierra continues to advance it waterflood
development program in line with the approved field development plan. A successful injectivity test in the Basal Tena in the Chanangue
field was completed, a key technical milestone supporting the water injection pilot. Construction of the associated water treatment and
injection facilities is progressing, targeting an early 2026 injection start. In parallel, the Company plans a second injector conversion
in the Basal Tena at Chanangue in the second quarter of 2026, alongside additional injector conversions in the Lower U at the Iguana and
Perico fields in second quarter and third quarter 2026, respectively.

· **Colombia** 

&nbsp;&nbsp;&nbsp;&nbsp;o **Cohembi:** At Cohembi North, infrastructure activities continue to progress in support of the Company's
forward drilling and development program, including cellar construction and associated electrical and mechanical tie-ins. Work is also
underway on Cohembi Pad 6, with additional cellars being constructed to provide flexibility for upcoming development and exploration activity.

&nbsp;&nbsp;&nbsp;&nbsp;o During the fourth quarter of 2025, gross production at Cohembi increased
to approximately 9,100 bopd, driven by the successful delivery of the Raju-1 well and a strong response from the ongoing waterflood program
in the northern portion of the field.

&nbsp;&nbsp;&nbsp;&nbsp;o As a follow-up, the Company plans to drill four gross development wells in Cohembi during the First Half
of 2026. The Company expects its capital carry commitments to be completed by mid-2026, after which working interest and cost sharing
will revert to standard terms, improving Gran Tierra's cash netbacks and capital efficiency on future activity.

· **Canada** 

&nbsp;&nbsp;&nbsp;&nbsp;o **Simonette:** At Simonette, Gran Tierra continues to see strong
operating performance, with recently drilled Lower Montney wells meeting or exceeding type curve expectations reinforcing confidence in
the asset's development potential and supporting stable production and cash flow generation going forward. To
date, three surface holes have been drilled from the 6-9 pad and are currently drilling the
16-14-061-01W6 well in the lateral section. The plan is to bring 5 gross wells onstream in Second Half of 2026.

&nbsp;&nbsp;&nbsp;&nbsp;o **Clearwater:** Gran Tierra is preparing to follow up Dawson
102/12-11 through advanced core analysis. Completion of the core study in 2026 will inform well design, mud system selection, and geological
modeling to maximize development value.

Such forward-looking statements include, but are not limited to, statements about the Company's estimated unaudited financial and operational results for the fiscal year ended December 31, 2025, including estimated total average production, estimated unaudited net debt, estimated capital expenditures, estimated revenues, estimated gross profit, estimated DD&A, estimated total operating expenses and estimated total operating expenses, estimated operating netback, estimated non-cash impairment charges for Canadian and Colombian long-lives assets, and estimated Adjusted EBITDA.

The forward-looking statements contained in this press release reflect several material factors and expectations and assumptions of Gran Tierra including, without limitation, that Gran Tierra will continue to conduct its operations in a manner consistent with its current expectations, the accuracy of testing and production results and seismic data, pricing and cost estimates (including with respect to commodity pricing and exchange rates), rig availability, the effects of drilling down-dip, the effects of waterflood and multi-stage fracture stimulation operations, the extent and effect of delivery disruptions, and the general continuance of current or, where applicable, assumed operational, regulatory and industry conditions in Canada, Colombia and Ecuador and areas of potential expansion, and the ability of Gran Tierra to execute its business and operational plans in the manner currently planned. Gran Tierra believes the material factors, expectations and assumptions reflected in the forward-looking statements are reasonable at this time, but no assurance can be given that these factors, expectations and assumptions will prove to be correct.

Among the important factors that could cause actual results to differ materially from those indicated by the forward-looking statements in this press release are: certain of Gran Tierra's operations are located in South America and unexpected problems can arise due to guerilla activity, strikes, local blockades or protests, civil unrest, sanctions-related restrictions, or other political instability; technical difficulties and operational difficulties may arise which impact the production, transport or sale of Gran Tierra's products; other disruptions to local operations; 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 a global health crisis, 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 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 and natural prices and oil and natural gas consumption more than Gran Tierra currently predicts, which could cause Gran Tierra to further modify its 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 Gran Tierra's products; the ability of Gran Tierra to execute its business plan, which may include acquisitions, and realize expected benefits from current or future initiatives; the risk that unexpected delays and difficulties in developing currently owned properties may occur; the ability to replace reserves and production and develop and manage reserves on an economically viable basis; the accuracy of testing and production results and seismic data, pricing and cost estimates (including with respect to commodity pricing and exchange rates); the risk profile of planned exploration activities; the effects of drilling down-dip; the effects of waterflood and multi-stage fracture stimulation operations; the extent and effect of delivery disruptions, equipment performance and costs; actions by third parties; the timely receipt of regulatory or other required approvals for Gran Tierra's 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 Gran Tierra's common stock or bonds; the risk that Gran Tierra does not receive the anticipated benefits of government programs, including government tax refunds; Gran Tierra's ability to comply with financial covenants in its credit agreement and indentures and make borrowings under its credit agreement; and the risk factors detailed from time to time in Gran Tierra's periodic reports filed with the SEC, including, without limitation, under the caption "Risk Factors" in Gran Tierra's Annual Report on Form 10-K for the year ended December 31, 2024 filed on February 24, 2025 and its other filings with the SEC. These filings are available on the SEC's website at http://www.sec.gov and on SEDAR at www.sedar.com.

**Non-GAAP Measures**

This press release includes non-GAAP financial measures as further described herein. These non-GAAP measures do not have a standardized meaning under GAAP. Investors are cautioned that these measures should not be construed as alternatives to oil and natural gas sales, net income or loss or other measures of financial performance as determined in accordance with GAAP. Gran Tierra's method of calculating these measures may differ from other companies and, accordingly, they may not be comparable to similar measures used by other companies.

Adjusted EBITDA is defined as EBITDA (defined as net income or loss adjusted for DD&A expenses, interest expense and income tax expense or recovery) adjusted for non-cash lease expense, lease payments, foreign exchange loss (gain), stock-based compensation expenses or recovery, transaction costs, other loss and unrealized derivative instruments loss (gain). Management uses this supplemental measure to analyze performance and income generated by our principal business activities prior to the consideration of how non-cash items affect that income, and believes that this financial measure is useful supplemental information for investors to analyze our performance and our financial results. A reconciliation from net income to Adjusted EBITDA is not available due to certain components of net income, including taxes and gain on debt securities, not being reasonably estimable at this time.

Net debt, as presented, is defined as Gran Tierra's senior notes and borrowings under Gran Tierra's credit facility, less cash and cash equivalents. Management believes that net debt is a useful supplemental measure for management and investors in order to evaluate the financial sustainability of the Company's business and leverage. A reconciliation from total debt to Net Debt is not available due to certain components of our total debt not being reasonably estimable at this time.

Operating netback, as presented, is defined as gross profit less 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.

**Unaudited Financial Information**

Certain financial and operating results included in this press release, including production information, net debt, capital expenditures, revenue, gross profit, DD&A, operating and transportation expenses, cash equivalents, operating netback, non-cash impairment charges and adjusted EBITDA, are based on unaudited estimated results. These estimated results have not been reviewed by Gran Tierra's auditor and are subject to change upon completion of the Company's audited financial statements for the year ended December 31, 2025, and changes could be material. Gran Tierra anticipates filing its audited financial statements and related management's discussion and analysis for the year ended December 31, 2025 on or before March 3, 2026.

**Presentation of Oil and Gas Information**

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

References to a formation where evidence of hydrocarbons has been encountered is not necessarily an indicator that hydrocarbons will be recoverable in commercial quantities or in any estimated volume. Gran Tierra's reported production, unless otherwise specified, is a mix of light crude oil and medium crude oil, heavy crude oil, tight oil, conventional natural gas, shale gas and natural gas liquids for which there is no precise breakdown since the Company's sales volumes typically represent blends of more than one product type. Well test results should be considered as preliminary and not necessarily indicative of long-term performance or of ultimate recovery. Well log interpretations indicating oil and gas accumulations are not necessarily indicative of future production or ultimate recovery. If it is indicated that a pressure transient analysis or well-test interpretation has not been carried out, any data disclosed in that respect should be considered preliminary until such analysis has been completed. References to thickness of "oil pay" or of a formation where evidence of hydrocarbons has been encountered is not necessarily an indicator that hydrocarbons will be recoverable in commercial quantities or in any estimated volume.

Boe's have been converted on the basis of six thousand cubic feet ("Mcf") natural gas to 1 bbl of oil. Boe's may be misleading, particularly if used in isolation. A boe conversion ratio of 6 Mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, given that the value ratio based on the current price of oil as compared with natural gas is significantly different from the energy equivalent of six to one, utilizing a boe conversion ratio of 6 Mcf: 1 bbl would be misleading as an indication of value.

Our obligation to accept Existing Notes tendered pursuant to the Exchange Offer and Consents delivered pursuant to the Solicitation is subject to the satisfaction of certain conditions described in the Exchange Offer Memorandum, which include, (i) the non-occurrence of an event or events or the likely non-occurrence of an event or events that would or might reasonably be expected to prohibit, restrict or delay the consummation of the Exchange Offer or materially impair the contemplated benefits to us of the Exchange Offer, (ii) the valid receipt (and not valid revocation) of the Consents of Eligible Holders of Existing Notes that, in the aggregate, represent not less than 66-2/3% in aggregate principal amount of the Existing Notes outstanding to effect the Proposed Amendments (the "**Required Holders**") prior to the Early Participation Deadline, (iii) the valid tender (and not valid withdrawal) of Existing Notes by Eligible Holders in the Exchange Offer that, in the aggregate, represent not less than 80% in aggregate principal amount of the Existing Notes outstanding prior to the Early Participation Deadline (the "**Minimum Exchange Condition**"), and (iv) the consummation of an incurrence of new indebtedness, on terms and subject to conditions satisfactory to us, that results in the receipt of net proceeds that are sufficient to pay the Cash Consideration (as defined below) (such condition the "**Financing Condition**"), certain other customary conditions. The Company reserves the right to waive the conditions to the Exchange Offer at any time.

Existing Notes tendered for their exchange on or prior to the Early Participation Deadline may be validly withdrawn, and the related Consents may be validly revoked, at any time prior to 5:00 p.m., New York City time, on February 11, 2026, unless extended by the Company, in its sole discretion (the "**Withdrawal Deadline**").

Eligible Holders who validly tender Existing Notes and deliver Consents, and do not validly revoke such tenders and Consents, on or prior to 5:00 p.m., New York City time, on February 11, 2026, unless extended or earlier terminated by the Company, in its sole discretion (the "**Early Participation Deadline**") and whose Existing Notes are accepted for exchange by the Company will receive for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, US$1,000 a portion of which will be payable in cash and the remainder will be payable in principal amount of New Notes (the "**Total Consideration**"). The Total Consideration includes an early participation premium for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline equal to US$50 (the "**Early Participation Premium**"), payable on the Early Settlement Date.

The aggregate cash consideration payable as part of the Total Consideration (which includes the Early Participation Premium) to all Eligible Holders whose Existing Notes are validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline and whose Existing Notes are accepted for exchange will be equal to an amount determined as follows: the aggregate cash consideration payable as part of the Total Consideration will be $110.0 million if 80% in aggregate principal amount of the outstanding Existing Notes are validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, with such aggregate cash consideration amount to increase by US$750,000 for each incremental 1.0% of aggregate principal amount of outstanding Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, up to maximum amount of cash consideration of US$125.0 million if 100% in aggregate principal amount of the outstanding Existing Notes are validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline (such amount, the "**Cash Consideration**"). The pro rata portion of the Cash Consideration as part of the Total Consideration for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, and accepted for exchange, will be determined at the Early Participation Deadline, based on the aggregate amount of Existing Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline.

The greater the amount of Existing Notes validly tendered (and not validly withdrawn), the lower the pro rata portion of the Cash Consideration per US$1,000 aggregate principal amount of Existing Notes tendered (and not validly withdrawn). For example: (i) if 100% of the Existing Notes outstanding is validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, each Eligible Holder will receive, for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn), approximately US$174.50 in cash and approximately US$825.50 in aggregate principal amount of New Notes, and (ii) if 80% of the Existing Notes outstanding is validly tendered (and not validly withdrawn) on or prior to the Early Participation Deadline, each Eligible Holder will receive, for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn), approximately US$191.95 in cash and approximately US$808.05 in aggregate principal amount of New Notes.

Eligible Holders who validly tender Existing Notes and deliver Consents after the Early Participation Deadline and on or prior to 5:00 p.m., New York City time, on February 27, 2026, unless extended by the Company, in its sole discretion (the "**Expiration Deadline**") and whose Existing Notes are accepted for exchange by us will receive for each US$1,000 aggregate principal amount of Existing Notes validly tendered (and not validly withdrawn), US$950 aggregate principal amount of New Notes (the "**Exchange Consideration**").

Eligible Holders whose Existing Notes are accepted for exchange will be paid accrued and unpaid interest on such Existing Notes from, and including, the most recent date on which interest was paid on such Holder's Existing Notes to, but not including, the Early Settlement Date or the Settlement Date, as applicable (the "**Accrued Interest**"), payable on the Early Settlement Date or the Settlement Date, as applicable. Accrued Interest will be paid in cash on the Early Settlement Date or the Settlement Date, as applicable. Interest will cease to accrue on the Early Settlement Date or the Settlement Date, as applicable, for all Existing Notes accepted for exchange in the Exchange Offer.

At any time after the Withdrawal Deadline and before the Expiration Deadline, if the Company has received the Consent of Required Holders of Existing Notes, the Company and the trustee under the Existing Indenture may execute and deliver a Supplemental Indenture to the Existing Indenture, which will give effect to the Proposed Amendments to the Existing Notes, that will be effective upon execution but will only become operative upon consummation of the Exchange Offer on the Early Settlement Date.

The Company will not receive any cash proceeds from the issuance of the New Notes in the Exchange Offer and the Solicitation. Existing Notes surrendered in connection with the Exchange Offer, and accepted for exchange, will be cancelled.

The Exchange Offer is made, and the New Notes will be offered and issued, only (a) in the United States to holders of Existing Notes who are reasonably believed to be "qualified institutional buyers" (as defined in Rule 144A under the Securities Act of 1933, as amended (the "**Securities Act**")) in reliance upon the exemption from the registration requirements of the Securities Act, and (b) outside the United States to holders of Existing Notes who are persons other than "U.S. persons" (as defined in Rule 902 under the Securities Act) in reliance upon Regulation S under the Securities Act and who are non-U.S. qualified offerees and eligible purchasers in other jurisdictions as set forth in the Exchange Offer Memorandum. Holders who have returned a duly completed eligibility letter certifying that they are within one of the categories described in the immediately preceding sentences are authorized to receive and review the Exchange Offer Memorandum and to participate in the Exchange Offer and the Solicitation (such holders, "**Eligible Holders**").

This press release does not constitute an offer to buy or the solicitation of an offer to sell the Existing Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. This press release does not constitute an offer to sell or the solicitation of an offer to buy the New Notes, nor shall there be any sale of the New Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. The New Notes will not be registered under the Securities Act or the securities laws of any state and may not be offered or sold in the United States absent registration or an exemption from the registration requirements of the Securities Act and applicable state securities laws.

The Exchange Offer is made, and the New Notes will be offered and issued in Canada on a private placement basis to holders of Existing Notes who are "accredited investors" and "permitted clients," each as defined under applicable Canadian provincial securities laws.

None of the Company, the dealer managers, the trustee, any agent or any affiliate of any of them makes any recommendation as to whether Eligible Holders should tender or refrain from tendering all or any portion of the principal amount of such Eligible Holder's Existing Notes for New Notes in the Exchange Offer or Consent to any of the Proposed Amendments to the Existing Indenture in the Solicitation. Eligible Holders will need to make their own decision as to whether to tender Existing Notes in the Exchange Offer and participate in the Solicitation and, if so, the principal amount of Existing Notes to tender.

This press release is being issued pursuant to and in accordance with Rule 135c under the Securities Act.
