Aug 7 (Reuters) - Greek oil refiner Helleniq Energy HEPr.AT on Thursday reported a 5% year-on-year decline in its adjusted core profit for the second quarter, citing reduced production from a scheduled full turnaround at the Elefsina refinery and weaker international crude oil prices, despite improved refining margins.
The group posted adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) of 221 million euros ($257 million), compared with 232 million euros a year earlier.
