COSAN S.A.
COSAN S.A. is a Public Limited Company registered in Brazil under 50746577000115, and its current status with Junta Comercial (state-level) / REDESIM federal portal is active. The company was incorporated on 8 July 1966 and lists its registered address as SAO PAULO, Brazil. 5 shareholders are on record for COSAN S.A., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Junta Comercial (state-level) / REDESIM federal portal and was last updated on 22 September 2026.

Shareholders
5
Five shareholders are currently on record for COSAN S.A., filed with Junta Comercial (state-level) / REDESIM federal portal.
The largest of these is Vanguard International Stock Index-Emerging Markets Stk, holding 18.5% — the largest recorded stake — followed by Renaissance Technologies, LLC at 4.7%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 26 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Chief Executive Officer of COSAN S.A. on record is Nelson Roseira Gomes Neto; 5 officers are shown here, filed with Junta Comercial (state-level) / REDESIM federal portal.
The register reports 18 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at COSAN S.A. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
COSAN S.A. has no recorded parent company — it sits at the top of its own group structure, with 16 subsidiaries recorded beneath it across 3 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 16 subsidiaries span Brazil, United States, Cayman Islands jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Two of the 16 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
