Tesla CEO Elon Musk announced global workforce reductions of "more than 10%" in an internal email to staff.
The layoffs come amid a tough start to the year for Tesla, with product deliveries falling 8.5% from the same period in 2023.
Tesla blames the drop in deliveries partly on factory shutdowns resulting from shipping diversions.
Tesla shares are down more than 30% this year, and Musk has slipped from his top spot on the Bloomberg Billionaires Index to third place.
Tesla employs approximately 140,470 people worldwide, from Texas to Shanghai,
and the reported 10% cuts could impact tens of thousands of workers.
Musk expressed gratitude to those remaining for the difficult job that remains ahead
and urged their resolve to help prepare the company for the next phase of growth.
