ApteraMotors Completes First Vehicle off Validation Assembly Line

Carlsbad,CA — March 3, 2026 — Aptera Motors Corp. (NASDAQ: SEV), a solar mobility company advancing ultra-efficient transportation, has completed the first vehicle off its validation assembly line, marking a major operational milestone as the company progresses toward regulatory certification and initial customer deliveries.

The company’s low-volume validation assembly line represents Aptera’s transition from hand-built validation vehicles to a structured assembly line process. The line consists of 14 dedicated stations, where vehicles are assembled by a team of vehicle line technicians, enabling repeatable builds, process verification, and optimization.

Vehicles produced on the low-volume validation line are allocated to specific testing programs, including thermal validation, brake performance, and some destructive testing. These efforts support the company’s advancement toward regulatory self-certification  , EPA certification, and progress toward delivering sellable vehicles.

“The completion of the first vehicle off our low-volume assembly line is a significant achievement for the entire company,” said Steve Fambro, Co-CEO of Aptera. “These first vehicles will be used to complete the key tests and optimization required to sell our first vehicles to customers.”

Equally significant is what this milestone represents for Aptera’s manufacturing process. The low-volume validation assembly line is being used to verify and refine the installation process for every major vehicle system. This allows the team to optimize build sequences, improve assembly procedures, and refine station layouts as preparation continues for the next phase of series volume assembly.

Following sustained hiring across key roles, Aptera’s assembly and integration organization has grown to become the company’s largest functional team, reflecting the beginning of its transition from engineering development to testing and production execution. Vehicles will continue rolling off the low-volume validation assembly line in the coming weeks as Aptera expands its validation fleet and advances through required testing and certification milestones.

With nearly 50,000 vehicle reservations representing over $2 billion in potential revenue, Aptera remains focused on disciplined execution as it works toward its target of delivering vehicles to customers later this year.
