The company has reported operating profits of SKr503m – a turnaround from the SKr99m loss for the same period last year.
Net revenue rose 5% to SKr5.8bn.
Södra attributes the positive result to higher demand and prices, and lower costs.
"We have had a good start to the year, with favourable performance and better earnings for all of Södra’s business areas," said president and CEO Lars Idermark.
"The improvement is due to our own efforts and better market conditions. The trend for the remainder of the year is largely dependent on market and exchange rate developments."
