DISCLAIMER

Promigas S.A., E. S. P. ("Promigas") is a Colombian securities issuer listed in the National Registry of Securities and Issuers. As such, it is required to comply with applicable Colombian securities regulations. It has additionally made commitments as an issuer with IR recognition from BVC, and has adopted high standards of corporate governance, risk management and criteria to identify, manage and disclose conflicts of interest, which also apply to its related companies.

Promigas is primarily governed by Law 142/1994, which establishes the Regime for Household Utility Services; CREG Resolution 071/1999, which establishes the Unified Transportation Regulation of Natural Gas (RUT, for the Spanish original) in Colombia, including their amendments; regulations of the sector; current concession contracts; the company bylaws and other provisions contained in the Code of Commerce.

The Separate Financial Statements have been prepared in accordance with Colombia's Generally Accepted Accounting and Financial Reporting Standards (NCIF, for the Spanish original), as set out in Law 1314/2009, regulated by Single Regulatory Decree 2420/2015, and as amended by

Decrees 2496/2015, 2131/2016, 2170/2017, 2483/2018, 2270/2019,1432/2020 and 938/2021. The applicable NCIF's in 2021 are based on the International Financial Reporting Standards (IFRS), including their interpretations, issued by the International Accounting Standards Board (IASB). The underlying standards are the Spanish translations officially issued by the IASB in the second half of 2020. The Company used the option allowed by Decree 1311/October 20, 2021, of recognizing in retained earnings under equity, and only for the 2021 period, the change in deferred income tax arising from the increase in the income tax rate established in Social Investment Law 2155.

These Separate Financial Statements were prepared in compliance with the legal provisions that apply to the Company as an independent legal entity, and they do not include the adjustments and eliminations required for the presentation of the consolidated financial position and the consolidated comprehensive income of the Company and its subsidiaries. Consequently, the Separate Financial Statements must be read in combination with the Consolidated Financial Statements of Promigas S.A. E.S.P. and its subsidiaries. For legal effects in Colombia, the principal financial statements are the Separate Financial Statements.
