June 24 (Reuters) - Viva Energy Group VEA.AX on Monday cut its half-year core earnings guidance for its retail segment, while its refining business was hit by weak regional refining margins.
The company expects underlying core earnings from its retail business for the first-half of fiscal 2019 of A$275 million to A$290 million ($190.69 million-$201.09 million), lower than its previous outlook range of A$286.9 million to A$291.9 million.
