Operating Expenses, Currency Fluctuation, and Rising Costs Pressure Second Quarter Balance of the Mining Giant
CSN Mining experienced a drastic drop in net income for the second quarter of 2025, recording R$ 115.8 million, which represents a retraction of 92.3% compared to the same period in 2024. The weak performance was primarily caused by the reversal of the financial result, which shifted from positive to strongly negative.
The financial result of the company was negative at R$ 750.1 million, compared to a gain of R$ 436 million in the previous year. The decline was attributed to increased financial expenses and currency fluctuation. In addition, the rise in costs and operational expenses compromised the profitability of the mining company controlled by CSN.
Revenue and Costs in Opposite Directions
Despite the significant drop in profit, CSN Mining’s net revenue was R$ 4.04 billion in the quarter, with a more modest decline of 3.6% compared to the previous year. The major impact came from the line of cost of goods and services sold (COGS), which totaled R$ 2.38 billion, an increase of 22.2% in one year.

Operating expenses also significantly increased, rising 39.7% to reach R$ 728.1 million. This cost escalation directly affected the adjusted Ebitda, which fell 21.7%, ending at R$ 1.27 billion in the quarter.
Tax Improvement Partially Eases Impact
One of the few positive indicators of the balance sheet was the improvement in the income tax and social contribution line, which dropped from a negative value of R$ 651 million in 2024 to R$ 66 million negative this year — an improvement of 89.9%.
Even with this tax relief, the set of negative factors — especially exchange rate effects and rising operational costs — determined the weak quarterly performance of CSN Mining, putting pressure on its position in the sector.
