U.S.-based data centre firm Equinix Inc (EQIX.O) on Monday said it had signed agreements for additional joint ventures with Singapore"s sovereign wealth fund GIC (GIC.UL) to add $3.9 billion to expand a data centre programme. The agreements for additional joint ventures in the form of limited liability partnerships with GIC, when closed, will bring the xScale data centre portfolio to more than $6.9 billion across 32 facilities globally, Equinix said in a statement. The joint venture projects are expected to close during the course of 2021. GIC will own an 80% equity interest in the future joint ventures and Equinix will own the remaining 20% equity interest, the statement added. Last year in April, Equinix signed a joint venture worth more than $1 billion with GIC to build three data centres in Japan for the cloud computing market.
