02:46 PM EDT, 08/15/2025 (MT Newswires) -- (Updates with NHTSA's comment and Rivian's petition in the last three paragraphs.)

Rivian Automotive ( RIVN ) said $100 million in revenue is on hold after the Trump administration eased US fuel economy rules, the Wall Street Journal reported on Friday.

The National Highway Traffic Safety Administration halted issuing compliance letters needed for selling fuel-economy credits as it reassesses Corporate Average Fuel Economy standards, the Journal said.

Rivian said it had already negotiated deals for credits but can't finalize them without the paperwork, the Wall Street Journal reported.

The delay, which also affects other EV makers, follows a Trump administration policy shift in July that removed penalties for violating the standards.

"NHTSA is focused on fixing CAFE standards to make cars more affordable again and overturning the illegal Biden-Buttigieg Electric Vehicle mandate. When that process is complete, we will return to issuing compliance letters to manufacturers," a NHTSA spokesperson told MT Newswires.

Rivian, which is part of the Zero Emission Transportation Association, or ZETA, told MT Newswires that it filed a petition on Aug. 6, asking a federal court to review a new rule from the NHTSA that changes how fuel economy standards are interpreted and enforced.

ZETA, which is an association of over three dozen companies advocating for the advancement of the electric vehicle supply chain, said in the petition that the rule harms its interests because the agency is now refusing to issue compliance notifications to vehicle manufacturers, which are required for selling fuel economy credits.
