July 22 (Reuters) - French semiconductor materials supplier Soitec SOIT.PA reported a 16% drop at constant exchange rates in its first-quarter sales, due to high customers' inventory and a weak automotive market.
The company posted quarterly revenue of 92 million euros ($108.14 million), down from 121 million euros a year earlier, but in line with analysts' average forecast of 93 million euros, according to a company-provided poll.
