(Bloomberg) -- Rivian Automotive Inc., the electric pickup maker backed by Amazon.com Inc., says it has received full regulatory certifications and can start delivering its debut electric vehicle to U.S. customers.

“Rivian vehicles are fully certified by NHTSA, EPA and CARB, and are ready for sale in all 50 states,” a Rivian spokesperson wrote in an email.

Rivian, based in Irvine, California, is seen as a front-runner in the larger pool of startups seeking to catch up with Tesla Inc., the market incumbent. 

Rivian has raised more than $10 billion from investors including Amazon, Ford Motor Co., T Rowe Price and Fidelity. Last month, Bloomberg reported Rivian had filed confidentially for an initial public offering and was seeking a valuation of around $80 billion.

R.J. Scaringe, Rivian’s chief executive officer, tweeted on Tuesday that the company had built its first production unit destined for a customer, a battery-electric pickup called the R1T. The company is aiming to deliver 100 units in the month of September, Bloomberg reported at the end of August.

Rivian is planning to start deliveries of its second EV, an SUV called R1S, at an unspecified date in the fall. The launch of both models have been delayed multiple times due to the global coronavirus pandemic and associated supply chain disruptions.
