Investors are seeking to pull out of a deal to invest in American Express Global Business Travel (GBT), according to published reports. Private equity firm Carlyle Group and Singapore sovereign wealth fund GIC announced last year that they would jointly buy a 20% stake in GBT for $900 million. GBT used to be entirely owned by American Express but was spun off as a joint venture in 2014 and is now 50%-owned by American Express. This is one of several deals that are being reconsidered due to the Covid-19 pandemic. The joint venture owners of GBT, which includes Certares and a Qatar sovereign wealth fund, are now involved in lawsuits with Carlyle and GIC in a Delaware court over the fate of the investment. None of the parties involved are making public statements. There is a June 30 deadline for the completion of the deal.
