Aptera Motors DrivesFirst Five Validation Vehicles Off the Line

Carlsbad,CA, May 12, 2026 — Aptera Motors Corp. (Nasdaq: SEV), a solar mobility company pioneering ultra-efficient transportation, today announced that five validation vehicles have been driven off its newly established low-volume validation assembly line.

Each vehicle has been built on Aptera’s low-volume validation assembly line in Carlsbad, California, where trained technicians move through 14 stations using processes designed to scale. Running multiple vehicles through the line in sequence validates not only the vehicle itself, but the system required to build it consistently.

With each successive build, the team has improved cycle times, refined workflows, and discovered improvements to carry onto future vehicle builds. The results are continuous improvements to a production system that is becoming faster, more efficient, and more predictable with every vehicle built.

“Every vehicle we run through this line teaches us something,” said Chris Anthony, Co-CEO of Aptera Motors. “With five vehicles now off the line, we have a growing foundation of data, a team that is getting sharper with every build, and a process that is proving itself in real time. That is what gives us confidence as we move toward our goal of customer deliveries.”

The validation fleet will continue to expand and move through a comprehensive testing program covering road performance, durability, safety verification, software and firmware integration, and real-world solar energy collection.

“What we are building here is not just vehicles, but the system to build them well,” said Steve Fambro, Co-CEO of Aptera Motors. “Each cycle through the line improves precision, efficiency, and repeatability. This is how we plan to meet our customers’ expectations when they finally get their hands on their own Aptera vehicle.”

With nearly 50,000 reservations on record, this milestone represents a critical step in transitioning from development to production.
