April 29 (Reuters) - German semiconductor materials supplier Siltronic WAFGn.DE reported lower-than-expected quarterly sales on Wednesday, due to a challenging market environment.
The company, which makes silicon wafers used in semiconductor chips, posted first-quarter revenue of 306.5 million euros ($359 million), down from 345.8 million euros a year earlier, and below analysts' average forecast of 317 million euros, according to a poll by LSEG.
