Rumo's net profit came in at 309 million reais, compared to gains of 51 million reais during the same period a year ago.

Net revenues meanwhile totaled 2.95 billion reais, up by half versus the same three-month period last year, reflecting a nearly 24% rise in the volumes it transported, especially corn, and a 23% increase in tariffs.

"Price dynamics for the second half of the year remain more favorable and freight prices showed an important correction throughout 2022," Rumo said in its quarterly report.
