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.

New standards
New standards	5. New standards 5.1 New standards adopted by the Group, effective as of January 1, 2023 The IASB issued amendments to the following standards, with an effective date on January 1, 2023, or later periods: ● 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. ● Modifications to IFRS 1: The amendment permits a subsidiary that elects to apply paragraph D16(a) of IFRS 1 to measure cumulative translation differences using the amounts reported in the parent’s consolidated financial statements, based on the parent’s date of transition to IFRS, if no adjustments were made for consolidation procedures and for the effects of the business combination in which the parent acquired the subsidiary. This amendment is also applied to an associate or joint venture that elects to apply paragraph D16(a) of IFRS 1. ● IFRS 3 - Business combinations: in which they update a reference from the standard to the Conceptual Framework. The amendments are intended to replace the reference to the Framework for the Preparation and Presentation of Financial Statements, issued in 1989, by the reference to the Conceptual Framework for Financial Information, issued in March 2018, without significantly changing its requirements. The amendments add an exception to the recognition principle of IFRS 3 to avoid the issue of potential ‘day 2’ gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets or IFRIC 21 Levies, if incurred separately. At the same time, the amendments add a new paragraph to IFRS 3 to clarify that contingent assets are not affected by the replace of Framework in the presentation of Financial Statements. ● Modifications to IFRS 9, IAS 39, and IFRS 7: Reform of reference interest rates. The amendments provide several exemptions that apply to all hedging relationships that are directly affected by the interest rate benchmark reform. A hedging relationship is affected if the reform gives rise to uncertainty about the timing and/or amount of the cash flows based on benchmarks of the hedged item or hedging instrument. ● 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% . This amendment is in process of analyzing its impacts within the Company. ● 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 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. ● Amendment IAS 21 - Effects of Variations in Foreign Currency Exchange Rates. The Amendment establishes criteria that allows assessing whether a currency is interchangeable and knowing when it is not. Thus, it will be possible to determine the exchange rate to be used and the disclosures to be provided. The Amendment applies to annual periods beginning on January 1, 2025. 5.2 New standards issued but not yet adopted. 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 is in an implementation phase and a significant effect on the Group’s consolidated financial statements is not expected given that most of the insurance contracts are short-term and would be managed by the PPA methodology - Simplified allocation of premiums. 5.3 New standards issued by the ISSB that with effect in future periods. The International Sustainability Standards Committee, in September 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. Ecopetrol Business Group is constantly monitoring changes in local accounting regulations to assess the possible impacts that the new standards issued by the international organization may generate in their adoption in Colombia.

Taxes	10. Taxes Income taxes 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: ​ ​ ​ ​ ​ ​ ​ ​ Nine-month period ended ​ ​ September 30, ​ 2023 2022 ​ ​ (Unaudited) Current income tax expense 10,378,745 13,586,947 Deferred income tax expense 1,025,705 2,613,356 Adjustments to prior years’ current and deferred tax 72,422 13,762 Income tax expense 11,476,872 16,214,065 ​ The effective tax rate for the nine-month period ended September 30, 2023, stood at 35.2%, while for the corresponding period in 2022, it was 37.1%. As of September 30, for both 2023, and 2022, the nominal income tax rate was set at 35%. The 1.9% decrease in the effective tax rate during the indicated period is mainly due to: (i) the best results obtained by Group companies whose nominal income tax rate is less than 35% and (ii) the effects of the exchange rate movements on Colombian companies such as Refinería de Cartagena and Ocensa, which use the U.S. dollar as their functional currency; among others. On December 2022, Tax reform Law 2277 established the deductibility of oil royalties paid to the Colombian Government for the exploitation of non-renewable resources is restricted, regardless of the denomination of the payment. On November 16, 2023, the Constitutional Court of Colombia delivered judgment C-489 of 2023; this ruling deemed the non-deductibility of royalties in income tax (measure featured in the most recent tax reform) as unenforceable. The repercussions of this verdict have been factored into in these financial statements. In December 2023, both the Ministry of Mines and Energy and the Ministry of Finance and Public Credit, respectively, submitted requests concerning the fiscal impact incidence and nullity related to the Constitutional Court’s ruling C-489 of 2023. As of now, there has been no ruling the Court regarding these requests.

Risk management	29. Risk management 29.1 Exchange rate risk The 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 September 30, 2023, the Colombian peso appreciated 15.73% from a closing rate of $4,810.20 on December 31, 2022, to $4,053.72 pesos per dollar. When the Colombian peso depreciates, export revenues, when converted to pesos, increase, and imports and foreign debt service become more expensive. The book values of financial assets and liabilities denominated in foreign currency are presented in the following table: ​ ​ ​ ​ ​ ​ ​ September 30, December 31, (USD$ Millions) ​ 2023 ​ 2022 ​ ​ (Unaudited) ​ ​ Cash and cash equivalents 765 615 Other financial assets 1,063 955 Trade receivables and payables (608) (392) Loans and borrowings (18,388) (16,113) Other assets and liabilities 98 202 Net liability position (17,070) (14,733) ​ Of the total net position, USD$(16,215) million correspond to net liabilities of companies with Colombian peso functional currency, of which USD$(16,563) 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$(348) million affects the statement of profit and loss. Likewise, USD$(855) 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 Sensitivity analysis for exchange rate risk 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 September 30, 2023: ​ ​ ​ ​ ​ ​ Scenario / variation in the Effect on income Effect on other exchange rate ​ before taxes +/– ​ comprehensive income +/ 1 % 24,385 796,716 5 % 121,925 3,983,580 ​ 29.3 In 2022 and 2021, were designated USD$4,340 million as a hedging instrument for its future revenues from crude oil exports, for the period 2022 – 2030; in accordance with IFRS 9 – Financial Instruments.

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 September 30, 2023, the total hedged balance is USD$10,298 million, which includes: i) Ecopetrol S.A. USD$10,100 million and ii) ISA Colombia for USD$198 million in hedge of net investment in the companies ISA REP, ISA Perú, Consorcio Transmantaro (CTM) and Proyectos de Infrastructura del Perú (PDI).

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 September 30, 2023, and December 31, 2022. 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 asset position in swaps for $12,619 (December 2022: asset $41,316). These transactions with financial derivatives are recognized under cash flow hedge accounting. 29.6 Risk and opportunities related to climate The Ecopetrol Business Group made progress in the process of identifying and assessing physical and transition climate risks, considering short, medium, and long-term climate scenarios. Physical and transition risks are often seen as opposites. The greatest transition risks are associated with the most aggressive reduction policies, with the goal of reaching net zero emissions, while the physical risks are greater in the lax policy scenarios, in which the increase in emissions is expected to cause more extreme weather events. For this reason, the IEA (International Energy Agency), the IPCC (Intergovernmental Panel on Climate Change), and the SSP (Shared Socioeconomic Pathways) have developed multiple future climate scenarios that reflect a series of political decisions and climate outcomes. ● Physical risks: related to the Company’s exposure and vulnerability to the impacts of climate change and climate variability in Colombia, which could affect the availability of water and increase the exposure of assets and operations to possible damage. o For the case of Ecopetrol S.A., the Company executed the analysis and the identification of seven (7) physical risks related to chronic threats (drought and thermal stress) and acute threats (precipitation, coastal flooding, fluvial flooding, fires, and winds) at 95 points associated with the company’s main assets. The modeling was carried out through Cervest’s EarthScan platform, using the following IPCC scenarios: (i) scenario aligned with the objective of the Paris Agreement (SSP1-RCP2.6), (ii) scenario peak emissions in 2040 (SSP2- RCP4.5), and (iii) business as usual scenario (SSP5- RCP8.5). EarthScan uses regional climate models with diverse data sets to analyze the physical vulnerability of assets, relative to the potential impact of climate hazards. The probability and severity of climatic events are estimated up to 2100. In addition, there is a vulnerability analysis for climate variability scenarios associated with the “El Niño” phenomena and its opposite phase “La Niña”. The frequency and intensity of these phenomena have been increasing in Colombian territory. ● Transition risk: related to the challenges that the company has identified to move towards a low-carbon, sustainable and competitive operation. The following are the identified risks: 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 for the application or modification of current and future licenses (GHG emissions, vulnerability and climate risks analysis, adaptation measures, among others), of which Ecopetrol Business Group could not have the information available, (ii) new regulations for the detection and repair of leaks, flaring, and venting of gas, (iii) disclosure requirements on environmental and social matters by the Financial Superintendence of Colombia, (iv) new requirements for project verification, (v) greater limitations on the use of offsetting to meet decarbonization goals, among others. 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. Ecopetrol S.A. defined a modeling exercise that prioritized market and regulatory risk, for the upstream segment, using the following analysis routes: (i) quantification of the impact on revenues derived from a changing demand for hydrocarbons, (ii) quantification of the impact in costs due to changes in carbon prices, and (iii) quantification of the financial repercussions derived from higher abatement costs associated with limitations on the use of offsets. The model used the International Energy Agency WEO 2022 scenarios: (i) Net Zero Emissions (NZE), (ii) Announced Pledges Scenario (APS), and (iii) Stated Policies Scenario (STEPS). The portfolio’s resilience was evaluated by comparing the net present value of future cash flows from the IEA scenarios with the net present value of Ecopetrol’s base case. In both cases, the hypotheses associated with the analysis routes were applied. The foregoing will be subject to review and assessment to establish the potential impact on the financial and strategic planning of the Company. The opportunities derive from the analysis of risks associated with the climate, the review of the energy transition scenarios, the implementation of the decarbonization plan and the alignment with the 2040 strategy. Opportunities have been identified related to the diversification of the traditional business, the incorporation into the portfolio of sustainable and low-emission businesses, the diversification in energy power and infrastructure markets, and the strengthening of energy efficiency and renewable energies.
