The rumors died down due to the lack of concrete offers. Twitter has also upgraded its offerings with several new features, including live video broadcasts from its app. "While none of them will likely materially change Twitter's user/usage growth, these product innovations are a positive step," RBC Capital Markets analysts wrote in a pre-earnings note. San Francisco-based Twitter was also hit by a string of executive departures in 2016, including in its product team, which has had three heads in less than a year. Twitter's net loss widened to US$167.1 million, or 23 cents per share, in the fourth quarter ended Dec 31, from US$90.24 million, or 13 cents per share, a year earlier. Restructuring charges in the latest quarter ballooned to US$101.2 million from US$12.9 million a year earlier. Twitter said in October it would cut 9 per cent of its global workforce as part of a broader restructuring.
