Rivian, a luxury EV maker, has delivered more vehicles between January and March than expected, outperforming analysts' expectations. The company reported delivering 10,236 vehicles in the first quarter ending March 31, 2026, and delivered 10,365 during the same period. This follows a partnership with Uber, which will invest up to $1.25 billion in Rivian and deploy up to 50,000 autonomous R2 vehicles on its ride-hailing platform within two years. However, analysts at JPMorgan have praised the deal as "mostly positive" as it will help Rivian navigate a "seemingly structurally unprofitable" market for electric vehicles. Despite a 48.9% year-over-year decrease in U.S. electric vehicle sales, dealerships, and other brands, the company saw a decline in sales due to a surge in demand ahead of the end of the government tax credit set to expire in 2025. Despite this, Rivian has reaffirmed its full-year delivery range between 62,000 and 67,000 vehicles.
