EARNINGS RELEASE | 4Q23 & 2023

Message from the Management

Throughout 2023, the strategic pillars of our investment thesis solidified, highlighting the countless opportunities inherent to our portfolio. In one hand, the relevance of onshore assets, which allows us to have greater predictability of production and revenues, low operational complexity and flexibility to adjust investment projects according to the future oil curve in the short and medium term. While in the other hand, the Company's offshore projects provide us with scale and enormous potential for increasing production in the coming years. Due to the low fraction recovered from the Papa Terra field, in the long term, this project could also play an important role in replenishing reserves, guaranteeing longevity for the Company. This combination of assets, together with optimized logistics, independence from third parties and its own infrastructure across the entire portfolio, transformed 3R into a unique company: the largest and most integrated onshore oil and gas producer in Brazil and one of the largest independent companies in the sector in Latin America.

In this context, we are preparing the Company to increasingly assume a leading role in revitalization projects in mature fields and production growth in the country, integrating a select group of companies that will support the gain in competitiveness of the oil and gas national industry and, consequently, encourage the improve of benefits that will extend throughout Brazilian society, generating revenue for the Union, states, municipalities and landowners, through the payment of royalties, taxes and fees linked to our businesses. It is worth emphasizing that our presence in the national territory generates opportunities to positively impact the economic and social dynamics of several municipalities where we operate, with relevant generation of employment and income, boosting the development of industry, suppliers and local commerce, especially in areas that historically have a low human development index.

The takeover of the Potiguar Cluster changed the scale and strategic potential of our thesis and was the main milestone reached in 2023. With the incorporation of the asset, 3R surpassed the 500 million barrels of 2P reserve, achieved record daily production in December, with more than 47 thousand barrels of oil equivalent, and established itself as the largest producer in the Potiguar Basin. Today, in addition to the oil and gas concessions, we also control the main flow, treatment, storage and refining infrastructure in the region, allowing an efficient and vertical operation, which serves not only our assets, but also other independent producers located in the same basin. Having its own storage, with capacity for more than 20 days of production, assets with logistics based on pipeline modalities and a private terminal to export and cabotage using medium and large capacity ships are strategic differences that are difficult to observe in any other onshore portfolio of E&P companies around of the world.

At the operational level, 3R achieved positive results in all four sedimentary basins throughout 2023, presenting organic growth of ~43% in assets operated since the beginning of the year, which highlights our operational execution capacity and the continuous improvement of controls internal and planning revitalization and investment projects. This result positions 3R among the independent companies with the best operational performance in 2023, with emphasis on Macau, where we delivered an increase in oil production of almost 80% throughout the year; and the assets in Bahia, where 4Q23 represented the ninth consecutive quarter with production increase. The Papa Terra project also deserves to be highlighted: even after taking over the asset with several restrictions on the processing and storage systems of the production units, after almost 10 months of unscheduled downtime, due to maintenance problems, by the former operator throughout 2022, 3R spared no efforts to recover the minimum integrity of the main systems and showed consistent evolution in 2023, reaching more than 90% operational efficiency in 4Q23 and around 63% growth in production if we compare 4Q23 with 1Q23.

EARNINGS RELEASE | 4Q23 & 2023

The strong operational performance, combined with a commercial strategy that evolved in every quarter of 2023, supported record net revenue of more than R$ 5.6 billion in the year or 3.3 times higher than the level presented in 2022. Revenue net revenue recorded in 2023 exceeded the sum of net revenues from the years 2020, 2021 and 2022 by more than R$ 2 billion. In line with the increase in revenues, we reached a record adjusted EBITDA of R$ 1.9 billion in the year, a value higher than the sum of adjusted EBITDA recorded in the last three years by more than R$ 700 million.

As a subsequent event in January 2024, 3R reopened the international debt market for first issuers in Latin America, which had been closed since the beginning of 2022, and concluded the first issuance of notes, in the amount of US$500 MM. Together with the issuance of two other issues of local debentures between November 2023 and February 2024, these instruments optimize our capital structure, provide greater flexibility in covenants and increase the average term of obligations, with a more efficient cost - in line with the profile of the Company's current risk. And not least, they reinforce the cash position to support our Capex plan, even considering more conservative Brent scenarios.

The evolution in all aspects of the business observed in 2023 is intrinsically related to the intense dedication of 3R employees, who do not deny their efforts to create one of the largest independent oil and gas production companies in Brazil.

We are a relatively new company, but modern and capable of adapting quickly to the challenges presented to us. We took advantage of Petrobras' divestment process like no other company. We reopened the capital market after almost 10 years without new companies listed in the oil and gas sector. Throughout the first half of 2023, we were faced with one of the Company's biggest challenges since its creation: a sequence of letters from the Ministry of Mines and Energy asking Petrobras to reevaluate the divestment processes. Even in this context, we managed to overcome all precedent conditions to complete the acquisition of Potiguar Cluster with a few months delay in relation to the original forecast. Finally, in 2024, we reopen the bond issuance market to new issuers in Latin America, as we have already mentioned. At 3R, we are driven by the feeling of ownership, and we are very proud to have built a Company with relevance in the sector and which presents robust results in a very short space of time. This is just the beginning of a long journey and, fortunately, we are still far from unlocking the full potential value of our portfolio. We are Energy to Redevelop, Rethink and Revitalize, in a safe, sustainable and, above all, independent way. WE ARE 3R!

ESG - Environmental, Social and Corporate Governance

The Company's strategic plan aligns the attention on operational and financial aspects with the development of ESG guidelines (Environmental, Social and Corporate Governance). In 2023, the Company reassessed its materiality grid in order to define the relevant topics that will serve as the basis for the evolution of the ESG Agenda.

Among the 11 topics defined as priorities, maintained from the previous grid, which are connected to the 17 Sustainable Development Goals (SDGs), the main ones are: operational safety, development of employees and local communities, biodiversity, health, safety and well-being, water and waste management, and compliance.

In its commitment to transparency with all stakeholders, the company presents below the key initiatives, projects and actions, in the respective spheres, during the 4th quarter and the year 2023:

Environmental

1. Partnership with UFERSA (Federal Rural University of the Semi-Arid): research project for the alternative use of water produced at the Fazenda Belém Cluster, with objectives aimed at environmental and operational issues. The water from the production process, which is currently treated and reinjected into the asset's reservoirs, has the potential to be reused
   in plantations, which may be considered in 3R's Annual Greenhouse Gas (GHG) Inventory. The project aims to use the water to irrigate oilseed crops (sunflower and safflower), biomass (elephant grass and sorghum), cotton and plants native to the region.

Reflorescer Project: Along with the Association of Agricultural Engineers of Rio Grande do Norte (ANEA/RN), 3R is coordinating the project with the aim of implementing socio-environmental actions, focused on restoring the forests of 60 hectares of Permanent

Preservation Areas (APP) and Legal Reserves in a rural settlement in the state of Rio Grande do Norte. Recently, 1,800 seedlings were distributed to 160 farming families, in order to strengthen family agriculture and contribute to the community's food security.

1. 3R Launches Caminhos do Mar Project: In collaboration with the FIA consultancy, the project aims to produce an audiovisual diagnosis on the impacts of the traffic of support vessels for the oil and gas supply chain operations in the influence area of the Ports of Vitória (ES) and Açu (RJ). The project's target audience is diverse, encompassing multiple users of the maritime zone who may be potentially affected by the traffic of support vessels in the oil and gas industry in the influence regions of these two ports.

3R Portfolio

The Company's upstream portfolio consists of 9 assets, located in four sedimentary basins and five Brazilian states:

• Potiguar Complex, which combines the oil and natural gas fields located onshore and near-shore in the Potiguar Basin;
• Recôncavo Complex, which combines the onshore oil and natural gas production fields in the Recôncavo Basin;
• Offshore Complex, which combines oil and natural gas production fields in shallow and deep waters (offshore) in the Campos and Espírito Santo Basins:

Peroá Cluster, which combines natural gas and oil condensate production fields located in shallow and deep waters (offshore) in the Espírito Santo Basin;

• Papa Terra Cluster, an offshore oil production field located in the Campos Basin.

A formation of asset complexes and exposure to the production of oil and natural gas are competitive advantages of the Company's diversified portfolio. This profile allows for significant integration of assets, capturing operational synergies, as well as increasing the scale and margin of the traded products.

Additionally, it is important to highlight that the natural gas production in the portfolio, besides being a source of revenue, serves as a crucial input for: (i) steam generation used in the development of heavy oil fields (low API grade) within the portfolio, (ii) consumption in refining activities, and (iii) self- generation of electrical energy through thermoelectric modules. These modules act as backups for the traditional energy supply from the regional distributor, particularly in Rio Grande do Norte.

By the end of 2023, the Company operated eight out of the nine acquired production poles, with only the operational transition of the Pescada Cluster still under Petrobras' operation.

The figure below123 illustrates the acquisition and portfolio construction flow of 3R, indicating the dates of signature and completion of transactions. In a consolidated view, the Company invested approximately US$ 2.2 billion in asset acquisitions, supported by sequential capital injections and debt instrument contracts.

1. Considering the amount paid for Macau (US$ 191 milhões) and Sanhaçu (US$ 6 milhões)
2. Asset operated by Petrobras, WI 65% in transition phase (acquisition price US$ 1,5 milhões)
3. WI 35% consolidated on the portfolio due to the merger of Ouro Preto Energia

EARNINGS RELEASE | 4Q23 & 2023

In addition to the portfolio of production assets (upstream), the Company has mid & downstream facilities located in Rio Grande do Norte, which were taken over by 3R on June 8, 2023: (i) the Clara Camarão Refinery, with a nominal installed processing capacity of approximately 40,000 barrels of oil per day, (ii) the Guamaré Aquatic Terminal (bonded private-use terminal), with high liquid storage capacity and mooring dolphins, enables the export, import, and domestic commercial flows through coastal shipping of crude oil and derivative products, (iii) the Guamaré Natural Gas Processing Units, with a combined installed capacity for processing approximately 5.7 million m³ per day (current effective capacity of 1.5 million m³ per day) and with a connection to the gas grid in the Northeast and Southeast of the country.

The Company's midstream and downstream facilities are located in a strategic region on the Brazilian coast, as they:

1. supply a significant part of its own production and that of third parties in the Potiguar Basin, (b) supply the regional market for derivative products, mostly interconnected by pipelines, with operations in the states of Rio Grande do Norte, Ceará and Paraíba, (c) access other markets, domestic and international, through the waterway terminal, and (d) are part of important cargo ship routes that pass along the Brazilian coast. The value generation of the segment goes beyond the monetization of the produced derivatives and includes facility sharing with third parties,

through usage fees, the provision of services inherent to the oil and gas industry, as well as commercial opportunities in trading activities and the monetization of upstream production.

The Company also highlights the complete integration between the upstream and mid & downstream segments in Rio Grande do Norte, expanding the diversification and value chain of the portfolio. Although 3R's focus remains on the upstream segment, integration between segments is an important generator of value for the entire production chain, as it: (i) it adds flexibility and independence to the flow of upstream production, with the refinery and the waterway terminal being direct monetization alternatives, (ii) it increases the Company's scale, by receiving and monetizing its own production and that of third parties (purchase of production from other operators in the Potiguar Basin and/or provision of storage and logistics services via the terminal), (iii) expands production storage capacity at the Guamaré Industrial Asset and allows for better development of the commercial strategy, and (iv) creates opportunities for the creation of new derivatives markets, regionally and in other locations, from the waterway terminal.

Reserves Certification

In terms of certified reserves, according to a report issued by the independent specialist firm DeGolyer and MacNaughton, as of December 31, 2022, the oil and natural gas concessions that comprise the Company's upstream portfolio had 516 million barrels of oil equivalent (boe) in 2P reserves (proven + probable), of which 367 million boe (or 71%) were proved reserves (1P) and 32% of the 2P reserves were classified as proved reserves developed in production (PDP), which demonstrates a low execution risk for 3R's operations. Of the total 2P reserves, 88% represented oil reserves and 12% natural gas.

Corporate Reorganization

In January 2024, the Company completed the first stage of the corporate reorganization process, merging the subsidiaries 3R Macau and 3R Fazenda Belém into the subsidiary 3R Areia Branca, renamed 3R RNCE, and the subsidiary 3R Rio Ventura into the subsidiary 3R Candeias, renamed 3R Bahia.

The operation focuses to simplify the organizational structure of the Company by consolidating operations in sedimentary basins, resulting in the optimization of operational costs and administrative expenses, as well as increased operational and commercial efficiency in portfolio management.

Considering that the subsidiaries involved in the operation are wholly owned by the Company, there will be no material impact on 3R and/or its shareholders regarding rights and duties related to the portfolio. The chart below provides details of the current Company structure after the completion of
