Insights

Equity and credit analyst

Large VAT assessment creates a potentially material liability for Ecopetrol.

Ecopetrol discloses that DIAN has confirmed a VAT and penalty assessment related to gasoline imports totaling COP 5.3 trillion, plus interest for late payment accrued from 2022 to 2024. This represents a sizeable potential outflow if ultimately payable and is tied to DIAN’s interpretation of customs and tax rules.

The company clearly states it disagrees with DIAN’s interpretation and expects to pursue legal actions under current tax and customs regulations. Until there is a final ruling or settlement, the actual financial effect remains contingent on the legal outcome, but the disclosed amount signals meaningful exposure on historical transactions.

Ecopetrol highlights that the process has been managed collaboratively with the tax authority and reaffirms its commitment to comply with its obligations and respect decisions by competent authorities. Future company communications and periodic reports will be important to understand any court decisions, potential payment requirements, or accounting recognition related to the COP 5.3 trillion assessment and associated interest.

Update on the VAT proceedings related to fuel imports

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) (the “Company” or “Ecopetrol”) reports that on January 22, 2026, the Colombian National Tax and Customs Authority (“DIAN”) notified Ecopetrol of Resolution 000571 (the “Resolution”), in accordance with its interpretation and customs procedures. By means of this Resolution, DIAN confirmed its prior decision issued in the Official Correction Assessment 6224-2078 dated August 25, 2025, which mandated the payment of certain Value Added Tax (VAT) on gasoline imports and a penalty, which together amount to COP 5.3 trillion, plus interest for late payment, accrued between 2022 and 2024.

As previously communicated, Ecopetrol has expressed its disagreement with DIAN’s decision and interpretation of the laws. Given that such difference in regulatory interpretation between DIAN and the Company remains, Ecopetrol expects to pursue the appropriate legal actions in accordance with current tax and customs regulations.

This legal dispute has been managed in a collaborative manner and within a framework of joint work between the company and the tax authority.
