Surtigas: as partner of Gases del Pacífico, it presents lower income via participation method due to lower profit from IFRS 15 recognition in 2020. Promioriente: This transportation company had volumes affected by an emergency in the Gibraltar-Bucaramanga gas pipeline from August 3 to December 15. Gasnorp (Perú): obtained better results in the concession construction business by IFRS 15 margin due to higher capex in line with the mass expansion plan for this concession, and better operating results due to the early entry of customers and their respective volumes.

Net Income for $256,104 MM (98% Budget) This account includes the decrease due to lower EBITDA, the impact of the higher depreciation and amortization due to the recording of provisions for the intelligent pig (internal cleaning of gas pipelines) to be carried out in 2022 and due to the recording of the deterioration and dismantling of gas pipelines due to replacement work. Likewise, there were higher financial expenses associated with the higher average debt balance and higher CPI (40% of our debt is indexed to this parameter, mainly COP bonds). 1 Revenue: Operating Revenue+ Participation Method#32FINANCIAL STATEMENTS PROMIGAS PROFIT AND LOSS STATEMENT | Individual Accumulated 2021 - Accumulated 2020 Revenue¹ ▲ 7% EBITDA ▲ 6% Net Income 1% 1,639,732 1,535,590 1,390,950 1,309,776 1,149,048 1,137,490 Figures in COP 2021 2020 Revenue for $1.6 Bn (110% Budget) Operational Revenue (8%): This item shows an increase due to higher billing TRM in 2021 ($3,690 in 2021 vs. $3,518 in 2020), while we had lower revenues in 2020 due to flexibility of contracts as a result of the pandemic to support our customers and was recorded in 2021 income from gas imbalance billed to Gases del Caribe for losses in the Barranquilla distribution network. • Participation Method (6%): Presented an increase for the following reasons: Gasnorp (Perú): obtained better results in the concession construction business by IFRS 15 margin due to higher capex in line with the mass expansion plan for this concession, and better operating results due to the early entry of customers and their respective volumes. · Cálidda (Perú): there was an increase due to higher invoiced volume and higher income from the sale of internal installations and connections; Likewise, a lower portfolio provision was recorded in 2021.

Net Income for $1.1 Bn (109% Budget) As the final line of our financial statements, this item accumulates the impact of the increase due to higher EBITDA, due to higher financial income generated by the disbursement of loans to related companies in the development of our corporate treasury management and due to the higher income from financial assets due to the update of operational and macroeconomic variables. The foregoing was partially reduced by higher financial expenses due to a higher average debt balance and higher CPI (40% of our debt is indexed to this parameter, bonds in COP mainly), and higher current income tax (lower tax benefit from the Legal stability due to lower investments due to rescheduling, as a result of limitations generated by covid-19 in our areas of influence). 1 Revenue: Operating Revenue+ Participation Method#34FINANCIAL STATEMENTS PROMIGAS BALANCE SHEET INDIVIDUAL December 2021 vs December 2020 Other current assets (9%): show an increase mainly due to the dividends decreed by the related companies in the March 2021 assemblies, which had an increase of 2% with respect to those decreed in 2020, and higher accounts receivable for the natural gas transportation service for the highest turnover. Financial assets (9%): this item includes the effect of updating the macroeconomic variables necessary to calculate the financial asset, which corresponds to the recognition of the potential account receivable from the Colombian State by virtue of the purchase option that the State has on the assets under concession. Otros Assets (21%): increase generated by the capitalizations made in Gases del Pacífico, Gases del Norte del Perú and Promigas Perú to strengthen their equity in the development of our investment plan for the massification of natural gas in Peru; The higher profits recorded by our affiliated companies via the equity method and the higher TRM, which is applied directly to the value of investments abroad (denominated in USD), also have a favorable effect. 47% Assets $9.3 Bn 11% (YTD) Figures in COP 4% 1% 21% Other LT assets Financial assets 27% Assets under concession Current Assets PP&E#35FINANCIAL STATEMENTS PROMIGAS BALANCE SHEET INDIVIDUAL December 2021 vs December 2020 Liabilities $4.3 Bn 7% YTD Equity $5.0 Bn 16% YTD Figures in COP LT Liabilities 10% 90% Current Liabilities Liabilities A7% (YTD) Current Liabilities (29%): increase in this account due to the transfer from long-term liabilities to debt bonds with short-term maturities, and balance due to the provision of an intelligent tool. Long-Term Liabilities (5%): increase for disbursement of credits and increase in the TRM that is applied to credits in dollars for the closing of financial statements. This difference is naturally covered at the level of assets by investments abroad, which are also registered with the highest exchange rate. For its part, the deferred tax presents an increase originated by the Tax Reform (the counterpart was taken to equity when accepting Decree 1311 of 2021).#36Q&A PCV 2809 PCV 28 PI 2820 PSV 28 PROMIGAS#37PCV 2809 PCV 28 ANNEXES PI 2820 PSV 28 PROMIGAS#38ANNEX PROMIGAS CASH FLOW STATEMENT Figures in Millions of Pesos Net Profit December 2021 1,149,048 156,686 Depreciations, Amortizations and Provisions Participation Method Dividends Received Changes in Assets/Liabilities -845,113 412,729 -47,018 Operational Flow 826,332 Investment in Capital Goods -382,219 Free Cash Flow 444,113 Disbursements of Loans 367,500 Amortizations -302,009 Permanent Investments Shareholders Cash Flow 509,604 Dividends Paid -505,367 Net Cash Flow 4,237 Initial Balance Final Balance 72,974 77,211#39PROFITABILITY INDICATORS PROMIGAS INDIVIDUAL Annual Indicators Quarterly Indicators 86% 87% 84% 85% 85% 82% 80% 81% 76% 74% 73% 72% 70% 70% 70% 61% 28% 30% 30% 26% 23% 23% 23% 23% 12% 14% 16% 17% 18% 12% 13% 15% 2018 2019 2020 2021 1T 2021 2T 2021 3T 2021 4T 2021 ROE ROA Margen EBITDA Margen Neto ROE ROA Margen EBITDA Margen Neto#40FINANCIAL STATEMENTS PROMIGAS PROFIT AND LOSS STATEMENT | Consolidated 4Q 2021 - 4Q 2020 Revenue¹ ▲ 10% EBITDA ▼ -37% 1,216,221 1,105,625 801,834 501,900 Utilidad neta ▼ -47% 265,046 500,984 Revenue (A10%) Operational Revenue (10%): Surtigas and GDO: increase in 2020 since there was a lower gross profit in the marketing and distribution businesses, of rights and materials and services, due to the lower consumption of non-regulated industries and as consequence of the COVID-19. CEO: higher distribution income due to the growth of the level 1 rate due to the transfer of the higher cost per IPP to the rate. Promigas: increase due to a higher average TRM in 2021. The foregoing was offset by Promioriente: impact on volumes due to an emergency in the Gibraltar-Bucaramanga gas pipeline from August 3 to December 15.

Net Income (A-47%) Decrease due to lower EBITDA, higher financial expenses due to higher interest rates and lower financial income. All the above was offset by a decrease in income tax due to a lower income tax rate and lower profit before income tax. 1 Revenue: Operating Revenue+ Participation Method#42FINANCIAL FINANCIEROS PROMIGAS PROFIT AND LOSS STATEMENT | Consolidated Accumulated 2021 - Accumulated 2020 Revenue1 ▲ 7% 4,495,236 EBITDA ▲ 1% 4,183,028 1,976,172 1,958,600 Figures in COP 2021 2020 Net Income -3% 1,137,445 1,099,133 Revenue (A7%) Operating Revenue (7%): Surtigas: higher profits in the natural gas business, NBF and materials and services, and lower financial costs. GDO: increase mainly due to better results in the natural gas business and lower provisions due to higher portfolio recovery. Promigas: increase due to higher billing TRM in 2021 (COP 3,690 in 2021 vs. COP 3,518 in 2020), lower revenues in 2020 due to contract flexibilization as a result of the pandemic and recording in 2021 of revenue from gas imbalance invoiced to Gases del Caribe due to losses in the distribution network. CEO: Greater gross profit in the distribution business thanks to an increase in level 1 rates, and lower impairment due to improved portfolio collections. Promigas Peru: higher revenues from natural gas sales. The above was offset by SPEC: decrease mainly due to lower regasification days in 2021 and the effect of the annual decrease in Va income due to its treatment as a financial asset under IFRS. Participation Method (18%): Cálidda: increase due to better results in the distribution business as a result of higher invoiced volume in the industrial and generator segments.

This was offset by higher costs and expenses as a result of the normalization of economic activities due to the end of the quarantine. Net Income (A-3%) Decrease due to higher depreciation and amortization mainly in Promigas due to capitalizations made at the end of 2020 and during 2021, and provisions for impairment, dismantling and abandonment of gas pipelines. Likewise, there was an increase in Promigas' income tax, since in 2020 there was a higher tax benefit for real productive fixed assets (due to the legal stability contract), as a result of higher investments made for expansion projects, and adjustment in deferred tax due to a change in the tax rate as a result of the tax reform. This was partially offset by higher non- operating revenue in Promisol, due to severance payments from Ecopetrol and Montecz, associated with the settlement of pending contracts, and lower non-operating expenses as donations were made in 2020 to combat the effects generated by the pandemic. Likewise, there was an increase in income from financial assets due to updating with real operating and macroeconomic variables, for those companies with concession contracts. 1 Revenue: Operating Revenue+ Participation Method#44FINANCIAL STATEMENTS PROMIGAS BALANCE SHEET | Consolidated Consolidated Balance Sheet December 2021 (COP) Assets $14.9 Bn A13% YTD Liabilities $9.7 Bn A12% YTD Equity $5.3 Bn A15% YTD 21% 15% Current Assets Assets $14.9 Bn 10% PP&E 21% A13% YTD ■Concessioned Assets Financial Asset 33% 17% Liabilities $9.7 Bn 83% ■Current Liabilities ■Long-term Liabilities A12% YTD Figures in COP#45PROFITABILITY INDICATORS PROMIGAS CONSOLIDATED Annual Indicators 41% 37% Quarterly Indicators 47% 45% 44% 42% 48% 41% 30% 27% 25% 24% 22% 22% 22% 21% 28% 26% 27% 25% 23% 22% 21% 21% 12% 13% 13% 11% 12% 13% 10% 11% 2018 2019 2020 2021 1T 2021 2T 2021 ROE ROA Margen EBITDA Margen Neto ROE ROA 3T 2021 Margen EBITDA 4T 2021 Margen Neto#46RESULTS BY SBU SBU TRANSPORTATION 4Q 2021 CONSOLIDATED REVENUE1 $1,216,221 MM Execution: 105% CONSOLIDATED EBITDA1 GAS NATURAL SOLUCIONES GNL INDUSTRIA 27% 34% $501,900 MM Execution: 109% CONSOLIDATED NET INCOME1 $265,046 MM Execution: 101% SBU DISTRIBUTION 6460046 GAS NATURAL FINANCIACIÓN NO BANCARIA 61% ENERGÍA ELECTRICA 12% 58% 8% 32% 67% 1% 29% 60% 11% ACCUMULATED DECEMBER 2021 CONSOLIDATED REVENUE1 $ 4,495,236 MM Execution: 100% CONSOLIDATED EBITDA1 $ 1,976,172 MM Execution: 108% CONSOLIDATED NET INCOME 1 $ 1,099,133 MM 42% 38% Execution: 104% Revenue A10% EBITDA A-37% Ne Income A-47% 4Q2021 vs. 4Q 2020 51% 57% Accumulated 2021 vs. 2020 Revenue A7% 7% 5% EBITDA A1% Net Income A-3% Note: (1) Revenue: Revenue + Participation Method + Dividends received, non controlled Revenue for concession construction.
