Shares in semiconductor equipment maker

Kulicke & Soffa

(KLIC) - Get Report

plunged in premarket trading Wednesday after the company slashed its revenue outlook for its fiscal fourth quarter.

Shares fell $1.47, or $22%, to $5.55, having hit 52-week lows on several occasions in early August.

The Willow Grove, Pa.-based company said it now expects revenue of $135 million to $165 million, vs. its previous forecast of $175 million to $195 million.

The consensus forecast of analysts is for revenue of $186 million.

"Discussions with customers indicate a general slowing in the rate of semiconductor growth, and as a result, wire bonder shipments for the September quarter will be lower than previously forecast," the company said.

The warning follows a cautious revenue outlook from networking giant
