Czech petrochemicals group Unipetrol will release its second quarter earnings on August 5 rather than on August 30 as originally planned, it said on Thursday in a statement on its website.

The downstream oil processor, majority owned by Poland's PKN Orlen, did not give a reason for the change.

It added it would release a trading statement for the period, which gives information on margins, foreign exchange exposure and an outlook for operating profit, on July 26, which is according to the original plan.
