Basis for preparation
Basis for preparation	2. Basis of presentation 2.1. Statement of compliance and authorization of financial statements The financial information contained in this report has been prepared in accordance with IAS 34 Interim Financial Reporting accepted in Colombia. The interim condensed consolidated financial statements are unaudited and in the management opinion, include all necessary adjustments for a fair presentation of the results of each period. Ecopetrol Business Group prepares its financial statements based on the principles and accounting standards and financial information accepted in Colombia (NCIF, as its acronym in Spanish), regulated in Decree 2420 of 2015 and its amendments. These standards are based on the International Financial Reporting Standards - IFRS and its Interpretations issued by the International Accounting Standards Board (IASB) and other applicable legal provisions for supervised entities and/or controlled by the General Accounting Office of the Nation. Some accounting standards and financial information accepted in Colombia (Colombian IFRS) may differ in certain aspects from IFRS as issued by the IASB. The accounting policies adopted in the preparation of the interim condensed consolidated financial statements are consistent with policies expected to follow in the preparation of the Group’s annual consolidated financial statements for the year ended December 31, 2024, which do not differ significantly from those used the immediately previous year. These interim condensed consolidated financial statements were approved by the Company’s Ecopetrol Board of Directors on September 27, 2024. 2.2. Basis of consolidation The interim condensed consolidated financial statements were prepared by consolidating all the subsidiary companies described in Exhibits 1 and 2, in which Ecopetrol exercises, directly or indirectly, control, according to IFRS 10.5 and 10.7. Subsidiaries are consolidated from the date control is obtained until the date control ceases. All intercompany assets and liabilities, equity, income, expenses, and cash flows related to transactions between Group companies were eliminated in consolidation. Unrealized profits and losses are also eliminated. Non-controlling interest represents the portion of profit, other comprehensive income and net assets in subsidiaries that are not attributable to Ecopetrol shareholders. The interim condensed consolidated financial statements were prepared on the basis that it will continue to operate as a going concern. All business combinations are recognized using the acquisition method.

Material accounting judgments and estimates
Material accounting judgments and estimates	3. Material accounting judgments and estimates The preparation of the consolidated financial statements requires that the Company’s Management make judgments, estimates and assumptions to quantify some of the assets, liabilities, income, expenses, and commitments recognized in the consolidated financial statements and their disclosures. These estimates have been made based on the best information available on the facts analyzed, management experience and other factors at the date of preparation of the financial statements. Uncertainty about assumptions and estimates could result in future material changes affecting the value of assets or liabilities. Changes in these estimates are recognized prospectively in the period in which they are reviewed. As of the date of this report, there have been no changes in the material accounting estimates and judgments used in the preparation of the financial statements as of December 31, 2023.

New standards
New standards	5. New standards 5.1. New standards adopted by the Group, effective as of January 1, 2024 The IASB issued amendments to the following standards with application as of January 1, 2023: Amendment to IAS 1 - Classifications of liabilities as current or non-current, modifies the requirement to classify a liability as current, by establishing that a liability is classified as current when it does not have the right at the end of the reporting period to defer the liquidation of the liability during, at least, the twelve months following the date of the reporting period. This amendment is effective since January 1, 2023. In addition, on October 31, 2022, IASB issued an amendment on non-current liabilities with agreed conditions and modified the effective date to January 1, 2024. IAS 12 Amendment: The IASB issued the amendment in May 2023, which provides to the companies a temporary exemption from accounting of deferred taxes arising from the international tax reform of the Organization for Economic Co-operation and Development (OECD), which published the rules to ensure that large multinational companies would be subject to a minimum tax rate of 15%. IFRS 17 - Insurance Contracts, provides a new general model for accounting for contracts by combining a measurement of the current balance of insurance contracts with the recognition of earnings during the period in which the services are rendered. The standard’s general model requires that insurance contract liabilities be measured using current weighted probability estimates of future cash flows, a risk adjustment, and a contractual service margin that represents the expected gain from fulfilling the contracts. The effects of changes in the estimates of future cash flows and the risk adjustment related to future services are recognized during the period in which the services are rendered and not immediately in profit loss statement. IFRS 17 replaces IFRS 4 - Insurance Contracts and will be effective for the subsidiaries Black Gold Re and Linear Systems Re Ltd for the financial reporting period beginning January 1, 2023. The assessment of the impact of IFRS 17 do not have a significant effect on the Group’s consolidated financial statements, considering that most of the insurance contracts are short-term and would be managed by the PPA methodology - Simplified allocation of premiums. The following limited-scope amendments, with comprehensive and anticipated voluntary application: ◾ Amendments to IAS 1 – Presentation of financial statements. Companies must disclose material information about their accounting policies and apply the concept of materiality to accounting policy disclosures. The amendments clarify the following points: - The word “significant” is changed to “material or relative importance”. - The accounting policies that must be disclosed in the notes to the financial statements are clarified, “an entity will disclose information about its material or relative importance accounting policies.” - It is clarified when an accounting policy is considered material or relatively important. - Adds the following paragraph: “Information on accounting policies that focuses on how an entity has applied the requirements of IFRS to its own circumstances provides specific information about the entity that is more useful to users of financial statements than standardized information or information that only doubles or summarizes the requirements of IFRS standards”. ◾ Amendments to IAS 8 – Accounting Policies, Changes in Accounting Estimates and Errors. They clarify how companies should distinguish changes in accounting policies from changes in accounting estimates. The amendment was published by the IASB in February 2021 and clearly defines an accounting estimate to distinguish it from an accounting policy: “Accounting estimates are monetary amounts, in financial statements, that are subject to measurement uncertainty”. It mentions “an accounting policy could require that elements of the financial statements be measured in a way that entails measurement uncertainty—that is, the accounting policy could require that these elements be measured by monetary amounts that cannot be directly observed and they must be estimated. In this case, an entity develops an accounting estimate to achieve the objective established by the accounting policy. ◾ Amendments to IAS 12 Deferred taxes related to assets and liabilities that are recognized in a single transaction. The purpose of the amendments is to reduce the diversity in the reporting of deferred taxes on leases and decommissioning obligations. The amendment allows the recognition of a deferred tax liability or asset that has arisen in a transaction that is not a business combination, in the initial recognition of an asset or liability that, at the time of the transaction, does not give rise to taxable temporary differences and deductibles in the same amount. ◾ Amendment IAS 7 - Cash Flow Statement and IFRS 7 - Financial instruments: Disclosures. The IASB issued the amendment on disclosure requirements to improve the transparency of suppliers financing arrangements and their effects on a company’s liabilities, cash flows and liquidity risk exposure. The Amendment applies to annual periods beginning on January 1, 2024. ◾ IFRS16 Amendment: In September 2022, the IASB issued an amendment related to the leasing standard regarding the recognition of the lease liability in a sale and leaseback. The amendment determines the requirements that a seller-lessee must use to quantify the lease liability arising in the sale and leaseback with the objective that the seller-lessee does not recognize any profit or loss related to the right of use that it retains. 5.2. New standards issued but not yet adopted. ◾ Amendment to IAS 21 - Effects of Changes in Foreign Currency Exchange Rates. The Amendment establishes the criteria to assess whether a currency is interchangeable and to know when it is not, so that the exchange rate to be used and the disclosures to be provided can be determined. The validity applies to annual periods beginning on or after January 1, 2025. ◾ Issuance of IFRS 18 - Presentation and disclosures in financial statements. This new IFRS standard has the purpose to improve the usefulness of the information presented and disclosed in financial statements and will provide investors with more transparent and comparable information on the financial performance of companies, allowing them to make better investment decisions. This new standard is effective internationally for annual reporting periods beginning on or after January 1, 2027, but companies can apply it early. It should be noted that IFRS 18 replaces IAS 1 – Presentation of financial statements. ◾ Issuance of IFRS 19 – Subsidiaries not in the public interest: disclosures. This new standard allows subsidiaries to disclose reduced information, instead of disclosing information in accordance with other IFRS. Thus, the application of this standard will reduce the costs of preparing the financial statements of subsidiaries, while maintaining the usefulness of the information for users of their financial statements. ◾ Narrow scope amendments to IFRS 9: These amendments will improve the consistency and understanding of accounting requirements by clarifying terms and procedures, introducing detailed disclosure requirements and allowing flexible early application, which will reduce diversity in accounting practice and increase the transparency and consistency of financial information. Amendments effective from January 1, 2026, and early application is allowed. 5.3. New standards issued by the ISSB that with effect in future periods. The International Sustainability Standards Committee, in June 2023 issued the first international sustainability and climate standards: IFRS S1 General Requirements for the Information to be Disclosed on Sustainability related to Financial Information and IFRS S2 Weather-related Disclosures. The purpose of these standards is for entities to disclose information about their risks and opportunities related to sustainability and climate that is useful to the primary users of financial information for decision-making. An entity will apply these standards for reports for annual periods beginning on or after January 1, 2024. The Ecopetrol Business Group is currently assessing the corresponding regulations and the methodology for their implementation. Likewise, the Ecopetrol Business Group will consider the guidelines and regulations that the Technical Council of Public Accounting may issue in Colombia.

Taxes	10. Taxes Income tax expense The Group calculates the income tax expense using the effective tax rate that would be applicable to the expected total annual earnings. The major components of income tax expense in the interim consolidated statement of profit or loss are: ​ ​ ​ ​ ​ ​ ​ ​ Six-month period ended ​ ​ June 30, ​ 2024 2023 ​ ​ (Unaudited) Current income tax expense 6,359,506 ​ 7,081,401 Deferred income tax expense 574,006 ​ (308,832) Adjustments to prior years’ current and deferred tax (19,484) ​ (8,643) Income tax expense 6,914,028 ​ 6,763,926 ​ The effective tax rate for six-month period ended June 30, 2024, and 2023 was 44.2% and 31.9%, respectively. As of June 30, 2024, and 2023, the nominal income tax rate was 35%, which includes an estimated surcharge of 15% for 2024 and 10% for 2023. These rates were estimated at each of the indicated dates, based on the projection of international BRENT prices. Pillar II Ecopetrol Business Group has a presence in the jurisdictions of Argentina, Bahamas, Brazil, Bolivia, Cayman, Chile, Colombia, Spain, United States, Mexico, Peru, Singapore, Panama, and Switzerland. The ongoing assessment is executed based on the latest available tax returns and the most recent country-by-country report for 2022, as well as the most updated financial information for 2024. Based on the current assessment, the Business Group has identified a potential exposure to Pillar II income taxes on profits obtained in Brazil, Singapore, Switzerland, and Bermuda, where the expected effective Pillar II tax rate is likely to be less than 15%. From the analysis on the implementation of Pillar II in the countries in which the Ecopetrol Business Group has a presence, it was identified that in some of them the regulations were issued to establish the Qualified Domestic Minimum Top-up Tax (QDMTT) as of January 1, 2024. However, the internal regulations for the Income Inclusion Rule (IIR) or the Undertaxed Profits Rule (UTPR) have not been established in any of these countries. For this reason, it is not possible to identify and allocate a possible additional tax in those jurisdictions whose Effective Tax Rate is less than 15%. The Business Group will continue to monitor the implementation of BEPS 2.0 in jurisdictions that already have progress. In addition, The Business Group is working on calculating the effective tax rate by jurisdiction. Therefore, the Ecopetrol Business Group will not recognize any impact in its condensed consolidated financial statements as of June 30, 2024. As well as applying the exception contemplated in the Amendment to IAS 12, the Company will not recognize deferred tax assets or liabilities associated with Pillar II income tax in its consolidated financial statement.

Risk management
Risk management	29. Risk management 29.1. Exchange rate risk Ecopetrol Business Group operates both in the local (Colombia) and international markets, for this reason, it is exposed to exchange rate risk, to a greater extent due to fluctuations in exchange rates, especially the peso/US dollar rate. As of June 30, 2024, the Colombian peso depreciated 7.86% from a closing rate of $3,822.04 on December 31, 2023, to $4,148.04 pesos per dollar. When the Colombian peso depreciates, export revenues, when converted to pesos, increase, and imports and foreign debt service become more expensive. The book values of financial assets and liabilities denominated in foreign currency are presented in the following table: ​ ​ ​ ​ ​ ​ ​ June 30, December 31, (USD$ Millions) ​ 2024 ​ 2023 ​ ​ (Unaudited) ​ ​ Cash and cash equivalents 806 ​ 554 Other financial assets 765 ​ 1,188 Trade receivables and payables (178) ​ (973) Loans and borrowings (18,838) ​ (18,470) Other assets and liabilities 25 ​ 268 Net liability position (17,420) ​ (17,433) ​ Of the total net position, USD$(16,590) million correspond to net liabilities of companies with Colombian peso functional currency, of which USD$(16,956) correspond to loans used as hedging instruments whose valuation is recognized in other comprehensive income, the exchange difference valuation of the remaining net assets for USD$366 million affects the statement of profit and loss. Likewise, USD$(830) million of the net position correspond to monetary assets and liabilities of Group companies with a functional currency other than the Colombian peso, whose valuation is recognized in the profit or loss statement. 29.2. The following is the effect that a variation of 1% and 5% would have in the exchange rate of Colombian pesos against the U.S. United States dollar, related to the exposure of financial assets and liabilities in foreign currency as of June 30, 2024: ​ ​ ​ ​ ​ ​ Scenario / variation in the Effect on income Effect on other exchange rate ​ before taxes +/– ​ comprehensive income +/ 1 % 19,255 ​ 703,334 5 % 96,273 ​ 3,516,669 ​ 29.3 . To express the effect of the natural hedge existing between exports and debt in the financial statements, the exchange rate risk materializes when exports are made. On September 30, 2015, the Board of Directors made the first designation of Ecopetrol’s debt as a hedging instrument for its future income from crude oil exports. The following is the movement of this non-derivative hedging instrument: ​ ​ ​ ​ ​ ​ ​ June 30, December 31, (USD$ Millions) ​ 2024 ​ 2023 ​ ​ (Unaudited) ​ ​ Opening balance 6,265 ​ 5,572 Reassignment of hedging instruments 290 ​ 970 Realized exports (290) ​ (970) Designation of new hedges — ​ 693 Closing balance 6,265 ​ 6,265 ​ The following is the movement in the other comprehensive income: ​ ​ ​ ​ ​ ​ ​ June 30, December 31, ​ ​ 2024 ​ 2023 ​ ​ (Unaudited) ​ ​ Opening balance (601,744) ​ 2,473,999 Exchange difference 2,016,943 ​ (5,194,529) Realized exports (Note 24) 40,114 ​ (479,779) Ineffectiveness 2,330 ​ (25,454) Deferred tax (908,135) ​ 2,624,019 Closing balance 549,508 ​ (601,744) ​ The expected reclassification of exchange differences accumulated in other comprehensive income to profit or loss is as follows: ​ ​ ​ ​ ​ ​ ​ ​ Year Before taxes Taxes After taxes 2024 ​ (140,853) ​ 61,879 ​ (78,974) 2025 ​ (288,815) ​ 127,101 ​ (161,714) 2026 (305,153) ​ 134,291 ​ (170,862) 2027 (23,853) ​ 10,497 ​ (13,356) 2028 (25,155) ​ 11,070 ​ (14,085) 2029 ​ (27,168) ​ 11,956 ​ (15,212) 2030 ​ (46,841) ​ 20,614 ​ (26,227) 2031 ​ (56,734) ​ 24,967 ​ (31,767) 2032 ​ (60,868) ​ 26,787 ​ (34,081) 2033 ​ (5,766) ​ 2,536 ​ (3,230) ​ ​ (981,206) ​ 431,698 ​ (549,508) ​ 29.4 . The Board of Directors approved the application of hedge accounting of net investment from June 8, 2016. The measure seeks to reduce the volatility of non-operating income due to the exchange difference. The hedge of a net investment applies to a portion of the investments the Company has in foreign currency, in this case in subsidiaries with the US dollars as their functional currency, using as hedging instrument a portion of the Company’s debt denominated in U.S. dollars. As of June 30, 2024, the total hedged balance is USD$10,695 million, which includes: i) Ecopetrol S.A. USD$10,365 million and ii) ISA Colombia for USD$330 million in hedge of net investment in the companies ISA REP, ISA Perú, Consorcio Transmantaro (CTM) and Proyectos de Infrastructura del Perú (PDI). The following is the movement in the other comprehensive income: ​ ​ ​ ​ ​ ​ ​ June 30, December 31, ​ ​ 2024 ​ 2023 ​ ​ (Unaudited) ​ ​ Opening balance 3,140,684 ​ 9,354,071 Exchange difference 3,571,287 ​ (8,973,470) Deferred tax (1,382,016) ​ 2,760,083 Closing balance 5,329,955 ​ 3,140,684 ​ 29.5 . Commodity Price risk The price risk of raw materials is associated with the Group’s operations, both exports and imports of crude oil, natural gas, and refined products. To mitigate this risk, the Group has implemented hedges to partially protect the results from price fluctuations, considering that part of the financial exposure under contracts for the purchase of crude oil and refined products depends on the international oil prices. The risk of such exposure is partially hedged in a natural way, as an integrated Group (with operations in the exploration and production, transportation and logistics and refining segments) and carries out both crude exports at international market prices and sales of refined products at prices correlated with international prices. The Group has a policy for the execution of (strategic and tactical) hedges and implemented processes, procedures, and controls for their management. The main purpose of the strategic hedging program is to protect the Group’s consolidated financial statements from the volatility of market variables in each period, to protect income and thus cash flow. During 2022, a hedging plan was executed to protect the cash against low price scenarios below the budget base price, in this sense, put options were purchased. There is not balance of these financial instruments as of June 30, 2024, and December 31, 2023. On the other hand, tactical hedges allow to capture value in trading operations and Asset Backed Trading (ABT), thereby mitigating the market risk of specific operations. In the trading activity, commitments in physical spot and forward contracts could represent an exposure to commodity price risk, in particular the risk associated with the volatility of the price of crude oil and refined products. Although this exposure is part of the natural risk of the production, refining, and marketing activity made by Ecopetrol, sometimes marketing, to maximize value capture, can concentrate the exposure to risk in terms of time and/or or indicator that differs from the Company’s natural price risk profile. As of the date of this report, Ecopetrol Business Group recognizes a total net liability position in swaps for $222 (December 2023: liability $6,350). These transactions with financial derivatives are recognized under cash flow hedge accounting. 29.6 . Risk and opportunities related to climate Ecopetrol Business Group has an identification of physical and transition risks considering short, medium, and long-term climate scenarios, and opportunities, based on energy transition scenarios that guide the company’s long-term strategic analysis. ● Physical risks: are related to the Company’s exposure and vulnerability to the impacts of climate change and climate variability, which could affect operational continuity and increase the exposure of assets to possible damages. Physical risks are classified as acute and chronic. o Acute risks are those caused by extreme weather events, whose frequency and intensity have been increasing due to the gradual increase in global temperature. In Colombian territory they are mainly reflected in the occurrence of the climate variability phenomenon “El Niño” and its opposite phase “La Niña”. These conditions could result in, among others, water shortages, heat waves, floods, and fires. At the end of 2023, the “El Niño” phenomenon was consolidated with strong intensity. By the second quarter, the conditions of the phenomenon weakened and the transition to the neutrality phase began. It is reported that, for the second quarter, there were no substantial impacts on the infrastructure or operations of the Ecopetrol Business Group. In relation to the “La Niña” phenomenon, it is in a state of surveillance, Ecopetrol is advancing in the preparation and monitoring phase for the potential impacts that may occur in the face of climatic threats of natural origin (floods, strong winds and mass movements, among others). o Chronic risks derive from a sustained change in the medium and long term in climate conditions, which for the Business Group can be reflected in the rise in sea level, thermal overload and droughts, beyond 2050. ● Transition risk: related to the challenges that the Business Group has identified to move towards a low-carbon, sustainable and competitive operation. The Business Group carried out a prioritization of transition risks to establish their financial impact, identifying the following: o Regulatory risk , associated with regulatory changes that may directly affect the Company in the short and medium term. Among the regulatory changes, the following can be highlighted: (i) new information requirements associated with mitigation and adaptation for the application or modification of current and future licenses, (ii) greater requirements associated with the regulations for the detection and repair of leaks. , gas flaring and venting, (iii) disclosure requirements on environmental and social issues by regulatory entities, (iv) new requirements for the assessment and verification of reduction projects and their registration in the National Registry of Gas Emissions Reductions Greenhouse Gases (RENARE), (v) possible restrictions on the voluntary compensation of GHG emissions, (vi) implementation of the National Program for Tradable Emissions Quotas (PNCTE), in which emission rights would be assigned, among others. During 2023, the National Environmental License Authority (ANLA) in Colombia, incorporated into applications for environmental licenses, modification of licenses or minor changes in production and exploration, requirements associated with the quantification of GHG emissions, mitigation actions, vulnerability analysis and climate risk, and adaptation actions, within the framework of the Comprehensive Business Climate Change Management Plan. The report of compliance with these requirements must be presented in the Environmental Compliance Reports (ICAs). For the second quarter of 2024, the requirement was applied for (2) files with a request for modification. The document associated with the PIGCCe is public for consult. o Legal risk , associated with the negative reactions and lawsuits against the climate action of Ecopetrol Business Group o Risk of assets trapped in the traditional business of hydrocarbon production, transportation, and refining, considering factors such as fuel demand prospects and asset profit horizons. o Market risk , related to the change in preferences in the use of low-carbon products in the long term, which implies a risk for the Company of not being able to meet market demand and of not advancing effectively in the development of these products and cost impact due to carbon price change. o Reputational risk , associated with the impossibility of responding in a timely way to the expectations and demand of investors and other interest groups to establish ambitious objectives regarding climate change, which would affect the image of the Company. o Technological risk , associated with the negative effects on the profitability of the business if there is no preparation and capacity to adapt to new technologies because of the transition process. The transition risk analysis considered the market and regulatory risks with the highest probability of materialization and were evaluated under the three scenarios of the World Energy Outlook 2022 of the International Energy Agency (IEA): (i) Net Zero Emissions (NZE), (ii) Announced Pledges Scenario (APS), and (iii) Stated Policies Scenario (STEPS). In market risk, as a first approximation, the impact on the value of the Upstream segment assets and their resilience to different hydrocarbon demand expectations was analyzed. In the APS and STEPS scenarios, the oil business shows resilience to volatility. However, this exercise cannot be considered absolute, since the IEA scenarios do not consider the dynamics of local energy demand, especially the natural gas market. With respect to regulation risk, the regulatory evolution related to the energy transition and climate change involves regulatory changes that may directly affect the Business Group in the short and medium term. The Business Group is committed to contributing significantly to national and sectoral goals, which in the future may be reflected in potential mandatory requirements. Faced with this risk, the Business Group evaluated two routes: i) quantification of the impact on the costs associated with a potential change in carbon prices and ii) quantification of the financial repercussions derived from higher abatement costs, due to limitations due to use of offsets, to analyze the effects on cash flow and possible capital allocation needs to enable the entry of new abatement opportunities to achieve decarbonization goals. To manage the indicated risks, the Business Group defined as strategic risk the “Inadequate response to challenges associated with climate change, water and biodiversity”, which incorporates treatment actions, Key Risk Indicators (KRI) and controls to effectively manage the causes and mitigate the materialization of the risk. This definition as corporate risk allows the Business Group to define actions to move towards decarbonization and the fulfillment of medium and long-term goals and adaptation to climate variability and normal weather conditions in the country, to mitigate the effects associated with availability and water security in the regions, energy security, among others. ● Opportunities associated with climate, these arise from the analysis of risks associated with climate, the review of energy transition scenarios, the implementation of the decarbonization plan and the alignment with the 2040 “Energy that Transforms” strategy. In the process of identifying and evaluating opportunities, the Company monitors and evaluates the energy market and the business environment, by defining energy transition scenarios that guide the long-term strategic analysis of the Business Group (2040). Opportunities have been identified related to the diversification of the traditional business, the incorporation of sustainable and low-emission businesses in the portfolio, diversification in the electricity and infrastructure market and the strengthening of energy efficiency and renewable energies. 29.7 . Capital management The main objective of Ecopetrol Business Group’s Capital Management is to ensure a financial structure that will optimize the Company’s cost of capital, maximize the returns to its shareholders and allow access to financial markets at a competitive cost to cover its financing needs.

Repsol Ductos Colombia. On July 22, 2024, Oleoducto Central S.A., belonging to the Ecopetrol Business Group, announced the acquisition of 100% of the shares of the company CI Repsol Ductos Colombia S.A.S. (“RDC”). RDC’s main asset is the shares in the Oleoducto de Colombia S.A. – ODC, which represent a 7.14% stake. The ODC is a private oil pipeline with an indefinite validity, which has been operating for 35 years transporting crude oil between the Vasconia Station, located in the municipality of Puerto Boyacá (Boyacá) and the Coveñas Maritime Terminal, in the municipalities of Coveñas (Sucre) and San Antero (Córdoba). ● Ecopetrol S.A. begins a partial refinancing of USD $250 million of debt maturities in 2026 On August 6, 2024, Ecopetrol S.A. reported that, as part of its comprehensive debt management strategy, it will prepay USD $250 million of its international bond maturing in June 2026, which was issued in 2015. The outstanding nominal balance of the bond is USD $1,500 million, with a coupon rate of 5.375%. The redemption date of the bonds will take place on September 5, 2024, at an approximate redemption price of USD $1,014.95 for each USD $1,000 of principal plus the accrued interest. The final amount of the transaction will be confirmed on the redemption date. The early payment is in line with the objectives of the financial plan and confirms Ecopetrol S.A.’s commitment to proactively manage the refinancing of maturities in 2026. ● Ecopetrol obtained authorization to execute a loan agreement with an international bank for two-hundred fifty million dollars Ecopetrol announced that the Ministry of Finance and Public Credit (“MHCP”) has authorized Ecopetrol to execute a loan agreement for up to two-hundred fifty million dollars The loan is expected to be executed by and between the Company, as borrower, and Sumitomo Mitsui Banking Corporation, as lender. The term of the loan is expected to be five years, with the principal payable at maturity and a variable interest rate. The proceeds from this transaction are expected to be allocated to non-investment expenses, including the repayment of financial commitments maturing 2026. According to the procedure outlined in the contract, the MHCP reviewed and authorized the terms, which anticipate borrower default events such as non-payment or failure to fulfill obligations. If these events materialize, the lenders may demand early repayment. Additionally, Ecopetrol may seek recourse if the agreed disbursements are not made. All of the above is in compliance and will be governed by the laws of the State of New York. ​
