We operate the majority of the refining capacity in Brazil. Our refining capacity is distributed across the Southeast, South and Northeast regions of Brazil, reaching the largest market share in these and other regions of the country through direct deliveries, pipelines and also via cabotage. We mostly meet our demand for oil products by domestic refining of crude oil, as defined in a periodic integrated operational planning process which constantly seeks to f maximize value for the company. We are also involved in the production of petrochemicals and biofuels through interests in companies.

We are responsible for the largest natural gas-powered thermoelectric operation in Brazil. Our plants play an important role in the supply and monetization of our own gas and in the secure operation of the electrical system with the higher share of renewable sources. Portfolio management of the generating complex is under permanent evaluation. In relation to natural gas, we operate in the areas of production, supply, processing, transportation, import of natural gas and import of Liquefied Natural Gas (LNG), regasification of LNG, supply of gas for internal consumption and markets sales.

In 2023, we reached another annual record in gas utilization, reaching 97.6% utilization in relation to the gas produced. Furthermore, it is worth mentioning that in december 2023 we reached the monthly record, with 98.2%.

Brazil has an integrated transport pipeline network that extends over almost the entire Brazilian coast, from Ceará to Rio Grande do Sul, in addition to reaching more inland regions of the country in Minas Gerais, São Paulo and Mato Grosso do Sul. Brazil also has an isolated system in the Northern Region that moves natural gas production from Urucu to Manaus. The transport pipeline network is operated by different transport companies, and we maintain a shareholding in TBG and TSB.

We participate in the Brazilian electricity market mainly through our investments in gas-thermoelectric plants, renewable energy and interests in fuel oil, diesel oil and natural gas plants.

As of 12/31/2023, we had activities in seven countries, in addition to Brazil: Argentina, Bolivia, Colombia, United States, Netherlands and Singapore. In Latin America, these activities mainly involve hydrocarbon exploration and production operations, mainly natural gas. In Colombia, we are also present in the liquid fuel retail segment. In North America, we produce oil and gas through a minority stake in a joint venture.

The year 2023 marked the resumption of our operations on the African continent, as part of the reserve replacementn strategy, with the acquisition of a stake in three exploration blocks operated by Shell, in São Tomé and Príncipe, announced to the market at the end of december.
