Petrolina (Holdings) Public Ltd. provided earnings guidance for the first half of 2016. For the period, the company's profits are expected to be increased compared to the corresponding results of the first half of 2015. It is, however, estimated that they will fluctuate around the same levels compared proportionately to last year's profits. The increase in profits compared to the corresponding period of last year is mainly due to the more efficient management of the gross profit margin, partly offset by increased sales and distribution expenses.
