CSN Claims Victory in $5 Billion Shareholder Dispute

By · · 2 min read

In a definitive legal victory, Companhia Siderrgica Nacional (CSN) saw its shares surge by 9.07%, closing at R$ 12.99 after reaching a high of R$ 13.44.

This jump came after Brazil’s Superior Court of Justice ruled in favor of CSN in a contentious $5 billion dispute with the Italian-Argentinian conglomerate Ternium.

The conflict arose over Ternium’s acquisition of a 27.7% stake in Usiminas in 2011. This acquisition did not include a public offer to buy out minority shareholders, despite CSN holding a 12.9% share.

The court’s decision underscored the alteration in control and management policies at Usiminas following Ternium’s purchase, necessitating the activation of the tag-along rights.

These rights are crucial for protecting minority shareholders during major corporate governance changes.

They ensure that minority shareholders can either exit the investment or sell their shares under equivalent terms as the major stakeholders.

Minister Antônio Carlos Ferreira, breaking a tie with his decisive vote, recognized Ternium’s increased sway in Usiminas’s decisions, particularly in appointing new executives.

He highlighted the judiciary’s commitment to maintaining economic order and fairness.
