Brazilian Court Orders Tenaris to Pay an Indemnification in Connection with its Acquisition of a Participation in Usiminas in 2012

LUXEMBOURG, June 18, 2024 (GLOBE NEWSWIRE) -- Tenaris S.A. (NYSE and Mexico: TS and EXM Italy: TEN) announced today that the Brazilian Superior Court of Justice (SCJ) resolved that Tenaris's subsidiary Confab and certain subsidiaries of Tenaris's affiliate Ternium, all of which compose the T/T Group under the Usiminas shareholders agreement, should pay Companhia Siderúrgica Nacional, or CSN, an indemnification in connection with the acquisition by the T/T Group of a participation in Usiminas in January 2012.

CSN and various entities affiliated with CSN had filed a lawsuit in Brazil against the T/T Group, alleging that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition.

On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals upheld the first instance court decision. On March 7, 2023, the SCJ rejected CSN's appeal by majority vote. The composition of the SCJ panel in charge of the case subsequently changed and CSN made several submissions in connection with the SCJ decision, including a motion for clarification with the SCJ that challenged the merits of its earlier decision.

At today's session, the SCJ completed its voting on CSN's motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and granted CSN an indemnification, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns. Depending on how the indemnification is calculated by other courts, and assuming monetary adjustment and interest through May 31, 2024, the potential aggregate indemnification payable by Confab could reach up to BRL942 million (approximately $180 million).

The Company continues to believe that all of CSN's claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator in February 2012 and December 2016, the first and second instance court decisions and the March 7, 2023 SCJ decision referred to above. The Company also believes that today's SCJ decision on CSN's motion for clarification is contrary to applicable substantive and procedural law. Accordingly, once the SCJ written votes are made available, Confab will file all available motions and appeals against the SCJ decision.
