Electric-vehicle startup Fisker has lost its second chief accounting officer in less than a month, the latest setback for a company that only recently started selling its first model. 

Florus Beuting, who was named chief accounting officer in early November, has left the automaker, the company said in a regulatory filing Monday. His exit follows the departure of his predecessor, who left in late October after roughly three years at the startup to take a job with another company, leading Fisker to unexpectedly delay its earnings release.
