Key Points
— Petrobras (B3:PETR4) and Novonor (Odebrecht’s successor) jointly nominated members for the new Braskem board ahead of Wednesday April 29 shareholder assembly — finalizing the governance shift that began with IG4 Capital’s purchase of Novonor’s 50.1 percent voting stake. Under the new shareholder agreement signed late April, Petrobras and IG4 will share control of Braskem with parity board representation and consensus-required deliberation framework.
— Board structure: 11 effective members plus alternates for a 2-year unified term running through Annual Shareholders’ Meeting reviewing 2027 fiscal year. Hector Nunez (Novonor nominee) becomes Chairman and Olavo Bentes David (Petrobras nominee) becomes Vice-Chairman. Petrobras CEO Magda Chambriard expected to ultimately assume Chairman role per Valor reporting.
— Petrobras stake math: currently 47 percent of voting capital + 36.1 percent total capital, but will gain governance parity through new shareholder agreement. Pre-transaction Novonor held 50.1 percent ON shares and 7 of 11 board seats, Petrobras held 4. Post-IG4 transaction with new agreement: Petrobras and IG4 each appoint equal directors and management. Transaction closes Q3 2026.

The Braskem board reshape concluding Wednesday closes the most consequential Brazilian petrochemical governance transition in 15 years — replacing Odebrecht’s post-Lava-Jato Novonor with private-equity IG4 while elevating Petrobras to genuine joint-control parity.
Brazil’s largest petrochemical company is closing its most consequential governance transition since the Lava Jato investigation. The Rio Times, the Latin American financial news outlet, reports that the Braskem board reshape concluding at Wednesday April 29’s shareholder assembly will replace Odebrecht-successor Novonor with private-equity firm IG4 Capital while elevating Petrobras to joint-control parity — finalizing the most consequential Brazilian petrochemical governance shift in 15 years and unlocking the structural restructuring framework Braskem has been pursuing since 2023.
“According to the New AA Braskem [Shareholders Agreement], the Company’s governance will be balanced between the Buyer and Petrobras, including the obligation to obtain consensus in all deliberations of the Board of Directors and the General Meeting, and the right of the parties to appoint an equal number of members to the Board of Directors and the Executive Management,” Braskem said in its SEC Form 6-K filing. The structural shift gives Petrobras the governance parity that the state oil major has been pursuing for over a decade.
The Braskem Board Reshape Mechanics
The new board structure has 11 effective members plus alternates for a unified 2-year term running through the 2027-fiscal-year shareholder meeting. Hector Nunez (Novonor nominee) becomes Chairman of the Board, with Olavo Bentes David (Petrobras nominee) as Vice-Chairman. Per Valor reporting, Petrobras CEO Magda Chambriard is expected to ultimately assume the Chairman role once IG4’s transition completes.
Other effective board members include Guilherme Simoes de Abreu, Rodrigo Tiradentes Montecchiari, Edmundo Jose Correia Aires, Joao Pinheiro Nogueira Batista, Juliana Sa Vieira Baiardi, Mauricio Dantas Bezerra, and Lucas Cive Barbosa. Three independent candidates round out the slate: Jose Mauro Mettrau Carneiro da Cunha, Carlos Plachta, and Gesner Jose de Oliveira Filho.
Pre-transaction governance: Novonor held 50.1 percent of ON (voting) shares and 7 of 11 board seats; Petrobras held 47 percent voting plus 36.1 percent total capital but only 4 seats. Post-IG4 transaction with the new shareholder agreement: Petrobras and IG4 each appoint equal directors and equal executive management members, with consensus required for all major decisions.

The IG4 Capital Acquisition Context
IG4 Capital — a Brazilian private-equity firm focused on infrastructure and special situations — acquired Novonor’s controlling stake through Shine I Fundo de Investimento em Participacoes (FIP), a vehicle managed by Vortex Capital and advised by IG4 Capital. The transaction was announced in late February 2026 and structurally restructured Braskem’s controlling-shareholder framework.
Petrobras’s strategic decision: in the February relevant-fact filing, Petrobras’s board confirmed it would not exercise right of first refusal nor tag-along rights in the Novonor-IG4 transaction. The choice meant Petrobras did not acquire the Novonor stake to become sole controller, nor sell its own stake. This deliberate non-exercise — combined with subsequent shareholder-agreement negotiation — secured Petrobras the governance parity outcome.
For IG4, Braskem represents the largest single investment in the firm’s portfolio. The Brazilian PE firm will deploy operational expertise from its previous portfolio companies (CCR, Engepar, Compass) to support Braskem’s structural restructuring. The 30-day post-closing window will produce the new shareholder agreement that formalizes the parity structure into operational decision-making.
Why This Matters for Braskem’s Future
Braskem has been a multi-year restructuring story since 2023, with excessive leverage, weak global petrochemical pricing, and the Alagoas mine-collapse environmental liabilities creating a structural-credibility deficit. The Novonor transition resolves the controlling-shareholder uncertainty that limited Braskem’s strategic options. With IG4 plus Petrobras providing balanced governance, Braskem can pursue debt restructuring, operational modernization, and possibly merger options that were previously blocked.
The structural read: Petrobras gains the operational influence over Braskem that aligns with its broader downstream-integration strategy, without the capital commitment of buying out Novonor entirely. IG4 brings PE discipline that should accelerate Braskem’s restructuring timeline. The combined framework should support Braskem’s debt-rating recovery and stock-price rerating through 2027.
XP analysts: the Petrobras-IG4 framework “could unlock” Braskem restructuring, with Brazilian institutional analysts expecting debt-restructuring announcements through Q2-Q3 2026. The combined entity has more credible negotiating leverage with Braskem creditors than the previous Novonor-led structure had. Braskem’s BRKM5 share price should benefit from the structural-uncertainty resolution.
What This Means for Petrochemical Investors
For BRKM5 shareholders, the governance transition is structurally positive: multi-year Lava-Jato-era ownership uncertainty resolved, PE-discipline plus state-major operational expertise combined for the first time, and the restructuring framework has a credible execution path. Near-term share-price volatility is likely as new governance executes, but medium-term rerating is supportive through 2027.
For Petrobras shareholders (PETR4), the Braskem governance shift adds incremental strategic value at zero capital cost. Petrobras gains co-control over a major downstream asset without paying the premium that buying out Novonor would have required. The arrangement is one of the most efficient strategic-acquisition outcomes in recent Brazilian state-major history.
For global petrochemical investors evaluating Latin American exposure, the Braskem governance resolution removes a structural overhang from the Latin American petrochemical sector. The post-Lava-Jato Brazilian petrochemical-restructuring story now has a credible institutional framework for completion. The structural rerating of Braskem versus regional peers (Mexichem, Indorama, Petroquimica de Venezuela) should compress the valuation discount through 2027.
