SAN FRANCISCO, Feb 10 (Reuters) - Rivian is

opening up sales of its delivery vans to fleets of all sizes in

the United States, the electric vehicle maker said on Monday,

more than a year after ending its exclusive deal with

shareholder Amazon ( AMZN ).

Rivian, known for its flagship R1S SUVs and R1T pickup

trucks, has seen demand beyond Amazon ( AMZN ) for its commercial vans

and has been testing them with large fleets.

Van sales, along with its plans to roll out its smaller,

less expensive R2 SUVs in 2026, will be crucial to Rivian's

success as broader demand for EVs has eased amid high borrowing

costs.

"Rivian has been trialing its commercial van with several

large fleets in the U.S., and preparing its fleet management

process for the mass market," the company said in a statement.

"These pilots have paved the way to enable Rivian to open sales

further."

Rivian ended its exclusive deal for van sales with Amazon ( AMZN ) in

late 2023 but reaffirmed its commitment to fulfilling an order

for 100,000 vans by 2030. Amazon ( AMZN ) currently has 20,000 Rivian

vans in its fleet.

After the exclusive ended, U.S. wireless carrier AT&T ( T )

was the first company to purchase some vans from Rivian in a

pilot program. It did not disclose the number of vehicles it

bought or the financial terms.

Rivian's announcement on Monday comes months after it

resolved a component shortage that hamstrung production of its

vans as well as SUVs and pickups.

Last month, the company surpassed analysts' expectations for

fourth-quarter deliveries. It has been cutting costs by

renegotiating supplier contracts and revamping its manufacturing

processes to turn a gross profit for the fourth quarter.

Rivian is set to report fourth-quarter results on February

20.
