 from another panel at the SCJ was summoned to produce the tie-breaking vote. On June 18, 2024, the SCJ completed its voting on CSN’s motion for clarification and reversed, by majority vote, its March 7, 2023 decision, and resolved that Confab and
the three subsidiaries of Ternium should pay CSN an indemnification in connection with the acquisition by the T/T Group of a participation in Usiminas in January 2012, with CSN being allowed to retain ownership of the Usiminas ordinary shares it currently owns.

On August 1, 2024, Confab and the other T/T Group entities filed a motion for clarification against the SCJ decision and, subsequently, CSN filed its reply. On December 6, 2024, the SCJ rejected this motion for clarification, confirming the obligation of Confab and the other T/T Group entities to pay indemnification in connection with the 2012 acquisition of the participations in Usiminas. Notwithstanding the foregoing, the SCJ unanimously resolved to modify the applicable monetary adjustment mechanism and to cap the applicable attorney’s fees, thereby lowering the aggregate amount that would be payable if CSN ultimately prevails in this claim. Based on such SCJ decision, assuming monetary adjustment through September 30, 2025, and attorney’s fees in the amount of BRL5 million, the revised aggregate amount potentially payable by Confab if CSN finally prevails on its claims, would be of approximately BRL610.6
million (approximately $114.8 million at the BRL/$ rate as of such date).

The Company continues to believe that all of CSN's claims and allegations are unsupported 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, and that in connection with the Usiminas acquisition the T/T Group was not required either to launch a tender offer or to pay indemnification to CSN. Accordingly, on February 10, 2025, Confab and the other T/T Group entities filed a request for extraordinary appeal against the SCJ decisions that ordered an indemnification payment, seeking their review and reversal by the Supreme Federal Tribunal. On September 10, 2025, the Vice-President of the SCJ, without examining the merits, denied leave to proceed
