Elon Musk tempered expectations for Tesla Inc.’s long-awaited battery day by cautioning that the company will unveil something that won’t be widely produced for two years.
Tesla shares fell as much as 6% and were down 5.2% at $425.97 as of 9:50 a.m. in New York. The pull-back comes after massive gains in recent months fueled in part by anticipation of the Sept. 22 event. Musk said the information he’ll announce will affect production of Tesla’s Semi, Cybertruck and Roadster models, all of which have been unveiled in the form of prototypes but are still in development.
