Rumo, controlled by Cosan, posted net profit of 30 million reais ($5.83 million) in the three months ending June 30.
Operating results, measured by adjusted earnings before taxes, interest, depreciation and amortization (EBITDA) reached 1.2 billion reais, up 4.8% year-on-year, but the EBITDA margin shrank 3 percentage points to 48.6%.
Total volume transported by the logistics company reached 18.6 billion equivalent tonnes (NTK), 4.1% higher than the previous year, as the 20.2% increase in its Northern operations volume offset the 19.6% fall in southern Brazil, which was affected by the corn crop failure.
