Brazilian petrochemical giant Braskem saw its shares jump 10% intraday on May 23, 2025, after Novonor confirmed receiving a non-binding acquisition proposal from investor Nelson Tanure.
The stock closed at R$11.09, a 9.15% gain, as markets reacted to the potential resolution of Braskem’s years-long ownership limbo.

Tanure’s bid targets Novonor’s 50.1% voting stake through his investment vehicle Petroquímica Verde, with exclusivity talks set for 90 days.
The offer arrives as NovonorBraskem’s majority owner since 2010, seeks to reduce its R$15 ($2.6) billion debt to creditor banks.
A 2025 restructuring plan involves transferring bank-held shares to a Geribá Investimentos-managed fund, leaving Novonor with 3–5% ownership.
Petrobras, which holds 47% of voting shares, is negotiating enhanced governance rights in parallel.
Braskem’s net debt reached $6.6 billion in Q1 2025, up 25% year-on-year, though quarterly net profit hit $113 million, reversing 2024’s $273 million loss.

Braskem’s bond issuances, including an 8% yield 10-year note in 2024, aimed to manage $1.85 billion in maturing debts.
The deal’s success hinges on Petrobras’ approval and creditor alignment, with BNDES president Aloizio Mercadante actively mediating.
If finalized, Tanure’s acquisition would mark Brazil’s largest industrial turnaround since Novonor’s 2018 bankruptcy, testing investor appetite for complex restructuring in volatile markets.
