Lucid denies bankruptcy and take-private report
The blog said restructuring adviser AlixPartners has urged the LCID board to conduct one more round of restructuring in the United States and Europe and narrow focus onto its Gravity SUV.
Lucid denied the report, calling it "completely false" and saying it is not considering going private or filing for Chapter 11 bankruptcy protection.
AlixPartners did not immediately respond to Reuters' requests for comment.
