Rivian Automotive Inc. warned that a Trump-era relaxation of U.S. fuel-economy penalties has blocked the company from booking roughly $100 million in revenue tied to the sale of regulatory credits. The National Highway Traffic Safety Administration has stopped issuing compliance letters—paperwork that buyers need to claim the credits—after the previous administration eliminated higher fines for carmakers that fail to meet corporate average fuel-economy (CAFE) standards. Rivian said the frozen credits accounted for about 6.5% of its revenue for the first half of 2025, underscoring how policy shifts are filtering through the electric-vehicle sector’s finances. The Zero Emission Transportation Association has petitioned the agency to reinstate the letter-issuing process, arguing that the delay is hurting both Rivian and peer manufacturers such as Lucid Group Inc.
