Twitter COO Adam Bain to leave, Noto to take his place

Twitter said on Wednesday that Chief Operating Officer Adam Bain, widely credited with building a robust advertising business at the company even as it struggled with user growth, is leaving to explore other opportunities. “Bain will remain at Twitter in the coming weeks to assist with the transition of the chief operating officer role,” the company said. The move is a blow for struggling Twitter, which has hired bankers to field acquisition offers but has seen a dearth of potential bidders. The company said last month it would cut 9 per cent of its global workforce to keep costs down. Twitter shares were down 4.3 per cent in after-hours trading. Bain will be replaced by Chief Financial Officer Anthony Noto (pictured), the company said, adding it would begin a search for a new CFO.
