The Japanese operator of global clothing heavyweight Uniqlo is expected to post a stronger quarterly profit on Thursday as its overseas units make up for slowing growth at home. The increase builds the first quarter, when Fast Retailing posted a 25% jump in earnings on the back of strong results in China, its biggest foreign market. The company conservatively left its forward guidance unchanged after those results, so second-quarter results may top consensus figures, according to LightStream Research analyst Oshadhi Kumarasiri.
