When Rivian Automotive Inc.’s shares sunk nearly 9% on Friday, analysts were puzzled as to why the electric-vehicle maker had to so drastically cut its 2024 production targets over yet another supply chain hiccup.

The answer lies in a miscommunication earlier this year between Rivian and its supplier, Atlanta-based Essex Furukawa, which has left the carmaker without access to copper windings, a core component in the electric-vehicle motors that Rivian makes in-house, according to people familiar with the matter.
