June 22 (Reuters) - EV maker Lucid Group ( LCID ) said on

Monday it would cut about 18% of its U.S. workforce and

announced COO Marc Winterhoff had left the company, in a major

shake-up aimed at boosting profitability amid growing

competition.

The layoffs will affect Lucid's full-time employees,

contractors and hourly production workers in manufacturing, and

are part of a broader restructuring plan, the company said.

It also said it has scrapped the second shift at its AMP-1

factory, its primary EV production facility.

Earlier this year, Lucid suspended its full-year forecast

and reported its biggest revenue miss in more than four years,

as a supplier-related issue disrupted deliveries of its Gravity

SUV in February.

Shares of the company were down 1.5% in premarket trading.
