Beuting, who expressed his intent to resign on Nov. 14, was named the accounting chief on Nov. 6 to succeed John Finnucan, who left the company in October after three years in the role.
Finnucan's departure led the electric-vehicle startup to delay its quarterly results after it flagged issues relating to internal controls over financial reporting.
The Wall Street Journal on Monday first reported on Beuting's exit citing people familiar with the matter. Shares of Fisker closed down 3.3% at $2.35, hitting another record low.
Separately, Fisker, which announced its third-quarter results on Nov. 13, said it received a notice from the New York Stock Exchange for late filing of its 10Q.
