Brazilian steel producer CSN faces a $172 million fine imposed by a federal court in Minas Gerais state for maintaining its stake in Usiminas. In the 2010s, CSN began acquiring shares of Usiminas, now owning 13.6% of its capital. The competition authority CADE ordered CSN to reduce its stake to 5%, but no deadline was specified, allowing delays. A 2024 deadline for the sale was set, but CSN did not comply. Now, CSN must either sell part of its Usiminas shares, pay the fine, or challenge the court's decision.
