U.S. cable company Comcast has previously said it hoped the acquisition would complete by the end of October.
Last month, Comcast emerged triumphant in the long-running battle for Sky after it beat Rupert Murdoch's Twenty-First Century Fox FOXA.O in an auction.
Comcast said in a regulatory filing on Thursday that by Oct. 9 when its acquisition of Twenty-First Century Fox’s 39 percent stake completes, it will hold or have received acceptances in respect of over 75 percent of Sky’s share capital.
The company said a further announcement will be made in due course.
