Prime Opportunities Investment, one of the four candidates seeking to buy IWG, does not intend to make a new offer for the company.
That leaves three candidates in the running to take over IWG: Starwood, TDR Capital and Terra Firma.
IWG has gained permission from the regulator to extend the deadline for a takeover of the group.
The trio now have until 7 August to make an offer.
IWG rejected an offer from Los Angeles-headquartered family office Prime Opportunities in May.
IWG is the world’s largest serviced office provider, and includes brands Regus and Space among its serviced office footprint.
