Amazon is quietly accumulating a stake in Einride, the Swedish electric trucking company that said Tuesday it will deploy 500 Tesla Semis for Amazon and other customers. Einride’s SEC filings show Amazon holding warrants for 25.2 million shares — about 12% of the company — that vest as Amazon buys freight services. The company’s financial report Tuesday, its first since going public in June, has the warrants on its books for the first time. At the same time, Einride is relying heavily on Amazon for growth, forecasting a 60% to 73% year-over-year revenue increase in the second half, “fueled by the Amazon ramp and other deployments in the U.S. and Europe,” as the company said in its earnings release. Amazon announced in April that Einride would deploy 75 electric trucks with charging at five U.S. sites in its middle-mile network, the leg between warehouses and delivery stations. Tesla Semi rollout: Einride also said Tuesday it will deploy 500 Tesla Semis across North America, calling it the largest deployment of Tesla’s electric big rigs in the world to date. The trucks will serve Amazon and other Einride customers on freight corridors in California, Texas, New Jersey, Illinois and Georgia, rolling out in phases over two years beginning in September, financed by third parties. This appears to be the first time Tesla Semis will haul Amazon freight. PepsiCo runs the largest fleet of Tesla Semis, close to 100 trucks, but Amazon has never been a named user. Amazon’s electric semis: Amazon has been turning to other manufacturers to electrify its freight network beyond the last-mile delivery vans it buys from Rivian. It deployed nearly 50 Volvo electric semis at Southern California ports and ordered more than 200 electric big rigs from Mercedes-Benz for Europe, part of a pledge to reach net-zero carbon
