Falling Brazil Steel Prices Drag CSN (SID) Into Deep Q3 Loss

U.S. investors holding New York-listed shares of Brazilian industrial giant Companhia Siderúrgica Nacional saw their positions drop on November 13, 2026, after the company posted a massive third-quarter net loss of R$ 1.25 billion. According to corporate filings reported by Reuters on November 13, 2026, this severe downturn completely reversed the net profit of R$ 76.4 million recorded during the same period in 2025. The swing was primarily triggered by a slump in international iron ore prices, mounting ocean shipping freights, and a high interest rate burden on the company's massive debt load.

This steel and basic materials sector downturn was heavily concentrated in the group's mining arm, CSN Mineração. According to financial statements submitted to Brazil's Securities and Exchange Commission (CVM) on November 12, 2026, the mining subsidiary swung to a net loss of R$ 356.3 million for the third quarter of 2026, down from a net profit of R$ 696.3 million a year earlier. Even though the miner kept sales volumes steady, the sharp decline in realized commodity prices and rising shipping costs severely compressed operating margins.

The parent company is also dealing with high financial leverage at a time when domestic borrowing costs remain elevated. CSN's adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) dropped 43.5% year-over-year to R$ 1.88 billion, as reported by InfoMoney on November 13, 2026. This sharp profitability decline pushed the company’s net debt-to-EBITDA leverage ratio up to 4.23x from 3.49x a year earlier, with total net debt rising 6.6% to R$ 44.92 billion. To cope with this leverage, management is aggressively selling off non-core assets, including the recent R$ 12.7 billion sale of its cement division to China's Huaxin.

Global markets responded with a sharp sell-off of both domestic and international equities. On the B3 exchange in São Paulo, CSN's local shares (CSNA3) plummeted 12.06% to end at R$ 3.72 on November 13, 2026, while the mining subsidiary's shares dropped 3.73%. Across the hemisphere, New York-listed American Depositary Receipts (ADRs) under the ticker SID plunged 10.94% to close at $0.6878 on November 13, 2026, hovering just above the stock’s 52-week low.

Looking ahead, investors will be monitoring the company's progress on further debt-reduction measures, including the finalization of its long-steel asset sales in Europe. For income-focused investors, the persistent losses and high debt are expected to severely restrict dividend payouts from both CSN and its mining subsidiary in the near term. The group's immediate capital priority is to maintain liquidity and fund its P15 mining expansion project, meaning there is very little room left for cash distribution.
