GlaxoSmithKline Scraps Float Plan for ViiV HIV Drugs unit

The company said the decision came following the unit's "updated strong positive outlook".

  Sales of HIV treatments rose more than 40% in the first quarter. 

The initial public offering (IPO) of ViiV could have been valued at up to £18bn, making it one of the biggest IPOs this decade.

In a statement, the company said: "Having reviewed this very positive outlook, GSK has concluded that retaining its full, existing holding in ViiV Healthcare is in the best interests of the Group and GSK will not now be initiating an IPO of a minority stake."

ViiV is a joint venture with US firm Pfizer and Japanese company Shiongi, with GSK owning about 80%.

GSK also reported first quarter sales of £5.6bn, in line with analysts' forecasts.

The company also said it would cut the amount of money being returned to shareholders following the deal it struck with Novartis last year.

Under the deal, Novartis bought GSK's cancer drugs business, while GSK bought Novartis' vaccines division. The two firms also combined their consumer health units.

GSK had planned to return £4bn to shareholders following the deal, but it now says it will return £1bn through a special dividend paid in the fourth quarter.
