(Reuters) – French conglomerate Bouygues reported a lower-than-expected first-quarter core loss on Thursday, citing the strong commercial performance of its telecoms business. The construction, telecoms and media group posted a current operating loss of 77 million euros ($80.93 million), stable compared to the same period last year and narrower than analysts’ forecast of a 90 million euros loss.
