Revenue (∆27%)

Revenue from ordinary activities (21%):increase due to the results of the following companies:

• Promigas: increase due to higher higher Representative Market Exchange Rate (TRM) used in 2022 for invoicing (COP $3,923 in 2022 vs COP $3,635 in 2021) and compensation received from Reficar, associated with the early termination of the gas transportation contract, which was replaced by another with flexibilities that benefit both parties and with a longer term.
• GDO: better results in the distribution business due to an increase in the volume of industrial customers, and Brilla, mainly due to a higher financing margin.
• Surtigas: increase in the commercialization business for consumption in the unregulated industry and better results in the NBF business.
• CEO: growth mainly in the distribution business due to higher tariff and revenue from sales in the regulated and non-regulated markets and by other marketers.
• Gasnorp (Perú): 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.

• Transmetano: Higher transportation revenues associated with the increase in transported volumes and registration of extraordinary income from the VINÚS Project concession due to compensation for the partial relocation of a section of the gas pipeline (950 meters).
• Gases del Pacífico (Perú): Better results in the natural gas business because of higher gas sales and higher tariffs in the residential, VNG and industrial sectors, as well an increase in the number of connections due to intensive commercial activity.
• Promioriente: higher results due to higher exchange rate in 2022 and registration of an indemnification received from the insurance company corresponding to an advance payment for lost profits due to an emergency presented in the Gibraltar- Bucaramanga gas pipeline from August 3 to December 15, 2021.

Revenue from Colombian and foreign concession agreements (83%):In line with the mandatory application of IFRS 15* in our Peruvian companies as of 2020, there is an increase in revenues from Gases del Norte de Perú due to higher capex in accordance with the concession massification plan.

EBITDA (∆39%)

In line with the mandatory application of IFRS 15* in our Peruvian companies as of 2020, there is an increase in revenues from Gases del Norte de Perú due to higher capex in accordance with the concession massification plan:

• Cálidda: increase due to the better results in the distribution and installation businesses due to more connected users and gain from the difference in exchange.
• Gases del Caribe: increase in the natural gas distribution business and better

results for Efigas and Gases de la Guajira via the participation method.

This was partially offset by higher costs and expenses because of the normalization of activities and organic growth in the operating activities of the portfolio companies.

Net Income (∆35%)

As our financial statement final line, this item, brings together the impact of the increase in EBITDA. This was partly reduced by higher financial expenses because of an increase in the debt balance, higher interest rates, and higher income tax due to the increase in pre- tax profit, a product of the positive results obtained.
