Over its history, it has built an extensive track record in infrastructure projects and engineering consulting services, with more than 3,500 contracts executed for around 400 clients across several segments, including transportation, sanitation, industry, housing, energy, environment, irrigation, urban development, and oil and gas. The company is headquartered in the state of Rio de Janeiro and maintains offices in Brazil, in São Paulo and Salvador, as well as international bases in Luanda, Angola, and Miami, United States, supporting its presence in projects in Brazil and abroad.

Sondotécnica Engenharia de Solos’ main activity is the provision of consulting engineering services. This includes the preparation of preliminary studies, master plans, feasibility studies, basic and detailed designs, as well as supervision, inspection, and management of works and technical services, with the provision of specialized labor. The company serves both the public and private sectors, participating in bidding processes, invitations, and direct awards, individually or in consortiums. Its capabilities include management, planning, supervision, and inspection of works, with an emphasis on transportation infrastructure projects, particularly metro-rail systems, in addition to operations in sanitation, hydraulics, environment, electricity, and oil and gas. The organizational structure is led by a CEO and four officers, who are responsible for the technical and administrative departments that operate in an integrated manner.

The company’s operations are segmented mainly by business area and type of service. In the 2025 breakdown, most sales are connected to the transportation, sanitation, housing, and urban infrastructure areas, with relevant diversification between “projects” and “supervision and management.” Supervision and management services account for the largest share, with 79% of revenue, while projects account for 21%. Among other services, the company offers modeling and management of privatization and concession processes, preparation and coordination of environmental studies, and technical support for obtaining the licenses required for the implementation and operation of projects, including manufacturing inspection, technical specifications, equipment assembly, pre-operational tests, and commissioning. The subsidiaries complement the scope of operations: Sondotécnica Participações Ltda. organizes equity interests and may perform management functions in investee companies; Sondotécnica Energia S.A. operates in Brazil focusing on consulting and technical and economic studies in the energy sector; and Sondotecnica International Co., together with Sondotecnica USA Corp and its stake in STZ Engineering, LLC, supports the company’s expansion and presence in engineering services in the North American market.

Sondotécnica’s client base is composed of public entities at the municipal, state, and federal levels, as well as private companies from different sectors. Among the most relevant clients in 2025 revenue are the Companhia de Desenvolvimento Habitacional e Urbano do Estado de São Paulo (CDHU) and the Agência Reguladora de Serviços Públicos Delegados de Transporte do Estado de São Paulo (ARTESP), which accounted for 16.4% and 11.2% of net revenue, respectively, in that year. These contracts are concentrated in consulting engineering services, project preparation, inspection and supervision of third-party project execution, as well as works management. The company is not dependent on specific suppliers to perform its services, since its main input base is linked to technical and specialized labor.

From a geographical standpoint, Sondotécnica’s operations are predominantly domestic. In 2025, 99.2% of net revenue originated in Brazil, with the domestic market historically accounting for almost all of the recent revenue. Angola appears as the main foreign market in the reported period, with around 0.8% of net revenue. Despite this, the company states it has a global presence, with a track record of projects in several countries in Latin America, Africa, and the Middle East, including Mexico, Guatemala, El Salvador, Panama, Colombia, Peru, Paraguay, Haiti, the Dominican Republic, Venezuela, Bolivia, Uruguay, Argentina, Senegal, Nigeria, Ghana, Equatorial Guinea, Congo, Angola, and Iraq. The provision of services abroad is subject to local legislation, including competition, environmental, corporate, and anti-corruption rules applicable in each jurisdiction where contracts are executed.

Sondotécnica’s activity is significantly influenced by the Brazilian regulatory environment, especially due to its high exposure to contracts with the public sector. The company participates in bidding processes governed mainly by Law No. 14,133/2021, which establishes the new framework for public procurement and administrative contracts, in addition to the specific rules of each contracting entity. The company is also registered with the Ministry of Defense as a private entity performing aerial surveying, in category “A,” valid until 2027, which enables it to operate in services that require this type of accreditation. In the context of environmental and social regulation, consulting activities often require interaction with licensing bodies, with Sondotécnica playing a technical support role in obtaining and managing environmental licenses for its clients, although such licenses are, as a rule, directly linked to the developers responsible for the projects.

From the standpoint of certifications and management systems, Sondotécnica Engenharia de Solos maintains an Integrated Management System, with ISO 9001:2015 (quality management), ISO 14001:2015 (environmental management) and ISO 45001:2018 (occupational health and safety management) certifications, valid until August 2025, granted by an internationally accredited entity. These certifications cover engineering consulting and design services, project management, and works supervision and inspection. The company also invests in technologies and design methods, with emphasis on its work in Building Information Modeling (BIM), in which it is one of the pioneers in creating digital models for public and private clients, and is a member of BIM Fórum Brasil. As a development of this innovation agenda, it maintains TECHLAB, an internal hub located in São Paulo aimed at promoting digital transformation, developing technological solutions, and fostering innovation in its services.

Regarding environmental, social, and governance (ESG) practices, Sondotécnica structures its management through corporate policies on compliance, anti-corruption, third-party contracting, and a Code of Ethics and Conduct, with periodic reviews to align with best practices and current legislation. The company states that it treats ESG as a strategic pillar for medium- and long-term value creation, with a culture that permeates the business chain and is supported by a management structure dedicated to identifying risks and opportunities. Since 2022, it has been a signatory of the UN Global Compact Network Brazil, committing to the ten principles related to human rights, labor, environment, and anti-corruption, and aligning particularly with Sustainable Development Goals (SDGs) 6, 8, 9, and 11. In 2023, it joined Instituto Ethos and adhered to the Business Pact for Integrity and Against Corruption, receiving the Clean Company seal. The company prepares its own ESG reports, with a second edition planned for the year 2025, including a materiality matrix and key performance indicators, still without independent assurance, and has set a goal of, within up to two years, incorporating international recommendations for climate-related financial disclosures.

The corporate governance structure of Sondotécnica Engenharia de Solos, as a company listed on B3 with shares SOND3, SOND5 and SOND6, is grounded in practices of transparency, integrity, and investor relations. The company maintains a compliance program developed in partnership with a specialized consultancy, defining principles that guide relations with employees, suppliers, clients, shareholders, and other stakeholders. Investor relations are treated as a strategic element for access to the capital markets, involving the disclosure of information on economic and financial performance, business strategy, and ESG developments. In this context, Sondotécnica combines a traditional consulting engineering practice with efforts in technological and institutional modernization, seeking continuous alignment with the regulatory environment and the governance requirements of the Brazilian capital market.
