Electric vehicle maker Rivian said Tuesday that it will allow other companies to purchase its fleet of delivery vans, ending an exclusive agreement with Amazon. In an announcement made alongside its third quarter earnings, the Irvine, California-based car maker said the decision provides other companies more opportunity to electrify their delivery fleets and reduce carbon emissions. The agreement with Amazon, made in 2019, included provisions that barred Rivian from selling commercial vans to other customers and provided Amazon exclusive access to the vans for four years from when it began receiving the EVs.
