UBS has landed a plum role advising a consortium of private equity investors on their acquisition of Inmarsat, the satellite communications company, in a deal that values it at $3.4bn.

The Swiss bank was the lead adviser to the group led by Apax and Warburg Pincus, the private equity firms, alongside the Canada Pension Plan Investment Board and the Ontario Teachers’ Pension Plan, which announced the plan to take Inmarsat private this morning through a $7.21-per-share deal.
