Hipgnosis Songs Fund shareholders have approved the music rights trust’s sale to Blackstone.
In a court meeting and general meeting, 99.97% of votes were cast in favour of the $1.58bn (£1.27bn) deal.
The last day of dealing for Hipgnosis shares will be 26 July, before the acquisition is implemented through a scheme of arrangement on 29 July.
Shareholders will receive proceeds of the sale by 12 August.
On 3 June, Blackstone increased the terms of its takeover bid for Hipgnosis.
Under the revised terms, the firm is set to pay $1.31 for each Hipgnosis share, representing a 49% premium to the 71p per share closing price on 18 April, before Blackstone’s bidding war with Concord Music began.
