Braskem's June 2026 ownership transition represents one of the most significant changes to the company's corporate structure since its creation in 2002. IG4 Capital, through the Shine I investment fund, took control of approximately 50.1% of Braskem's voting shares, replacing Novonor as the controlling shareholder. Petrobras retained its 47.03% voting stake, creating a new shared-control structure between IG4 and the state-owned oil company.
Braskem's historical ownership was closely connected to the Odebrecht Group, which acquired control of Copene in 2001 before merging it with five other companies to create Braskem in August 2002. Over the following years, Braskem consolidated Brazil's fragmented petrochemical industry, with Petrobras becoming an increasingly important shareholder. By the 2010s, the familiar structure had emerged: Novonor, formerly Odebrecht, controlled 50.1% of voting shares, while Petrobras held approximately 47%.
The transition to IG4 is therefore not simply a change in financial ownership. It represents the replacement of the shareholder that had exercised control over Braskem for more than two decades. Before the transaction, Novonor held 38.3% of total capital and 50.1% of voting capital, while Petrobras held 36.1% and 47%, respectively. After the June transaction, Shine I holds 34.32% of total capital and 50.11% of voting capital, while Petrobras remains at 36.15% and 47.03%.
One of the most important aspects of the transition is that Petrobras did not exit alongside Novonor. Instead, it agreed to a new shareholders' agreement with Shine I that establishes joint control, including consensus requirements for corporate decisions and equal representation on Braskem's board and executive leadership. Petrobras subsequently reclassified its Braskem investment from an associate to a joint venture.
For IG4, acquiring control means taking responsibility for a company with a large international industrial footprint but also significant financial challenges. Braskem has faced weak global petrochemical margins, excess capacity and major liabilities, and in August 2026 sought an out-of-court restructuring for approximately $10.9 billion of debt. That makes the ownership transition particularly consequential: IG4 is not acquiring Braskem during a conventional expansion cycle but taking control while the company is undergoing a major financial and strategic reset.
The scale of Braskem's ownership transition becomes clearer when viewed historically. The company has moved from its 2002 formation under the Odebrecht Group, through a long-standing Novonor-Petrobras control arrangement, to a new IG4-Petrobras shared-control model in 2026. The transaction therefore marks a structural break in Braskem's corporate history, while Petrobras' continued 47% voting stake provides significant continuity. The real test now is whether IG4's ownership can translate that structural change into financial stabilization and a sustainable turnaround.
