Twitter Inc said it would lay off up to 336 employees, or cut about 8 percent of its global workforce, as part of an overall plan to streamline operations.
The layoffs come about a week after the microblogging service provider appointed its co-founder Jack Dorsey its permanent CEO.
Twitter shares rose 2.3 percent to $29.41 in premarket trading on Tuesday.
Twitter said it expected to incur about $10 million-$20 million in severance costs and $5 million-$15 million in restructuring costs.
The company said it expected to record most of these pretax restructuring charges in the quarter ended Dec. 31.
