CSN Mineração’s Q2 Profit Jumps Nearly 89% Even as Its Revenue Falls
Brazil · Business
The near-doubling of net income owes little to the mine itself. Because a lighter currency drag on the company’s dollar accounts did most of the heavy lifting this quarter.
CSN Mineração, the iron-ore arm of Brazilian steelmaker CSN, saw its second-quarter profit climb nearly 89% from a year earlier. The eye-catching part is that revenue and core earnings both shrank over the same stretch.
So the jump came from somewhere other than the mine.
What CSN Mineração reported
The company earned net income of R$219.3 million, roughly US$41 million, in the second quarter of 2026. That was up nearly 89% from the R$115.8 million, about US$21 million, it made in the same quarter last year.
At first glance that looks like a mining business firing on all cylinders, but the reality is more layered.
Why the profit rose while revenue fell
Net revenue actually fell 15.8% to R$2.867 billion, about US$531 million, over the year. Adjusted EBITDA, the cleanest read on how the mine itself is doing, dropped 19.7% to R$1.018 billion.
So the operating business was softer, which means the higher profit had to come from further down the accounts.

The currency drag that eased
The real driver was the financial result, the line that captures interest costs and swings in the exchange rate. It stayed negative at R$491 million, about US$91 million, but that was 34.5% less painful than a year earlier.
A smaller drag on the company’s dollar-denominated cash and debt was enough to lift the bottom line sharply.
A weak comparison a year earlier
It also helps to remember where the profit is climbing from, because last year set a low bar. In the second quarter of 2025, net income had already shrunk to just R$115.8 million, a subdued figure.
Rising nearly 89% off that modest base looks dramatic, yet the absolute profit is still fairly slim for a miner this size.
The operating picture was softer
Strip out the financial line and the underlying operation clearly had a tougher three months than last year. Both revenue and EBITDA fell by double digits, a sign that selling iron ore was simply less lucrative.
The EBITDA margin still landed near 35.5%, healthy for the sector, but down from the richer levels of a year ago.
Iron ore volumes held their ground
One number barely moved, and that is how much iron ore the company actually shipped to customers. Sales came in at 11.849 million tonnes, up a whisker at 0.1% from the same quarter a year earlier.
So this was not a story of a mine slowing down, but of each tonne fetching less money than before.
What moved iron ore prices
Iron ore is a global commodity, and its price rides on how hungry the world’s steel mills are, especially in China. When Chinese construction and steel output cool, demand softens and prices ease back for every exporter.
That is the backdrop behind the lower revenue, even though the tonnes leaving CSN’s mines held steady.
Why the exchange rate matters so much
CSN Mineração sells its ore in dollars but reports its results in reais, so the exchange rate colours every quarter. It also carries dollar-linked debt, whose value in reais rises and falls as the currency moves around.
That is why the financial result can swing profit far more than a modest change in the price of ore.
What this means for investors
The headline profit jump is real, but it says more about currency and financing than about mining itself. A patient reader would watch EBITDA and sales volumes, the numbers that show how the core machine is running.
On that measure the quarter was steady on volume and softer on price, a more sober picture than the profit line suggests.
What to watch next
The two things to follow are the global iron ore price and the strength of Chinese steel demand. The real against the dollar will keep nudging reported profit up and down, so EBITDA is the steadier gauge.
If ore prices firm up while volumes hold, CSN Mineração’s earnings could look a good deal healthier than they do today.
