Tesla to Buy Battery-Tech Firm Maxwell for $218 Million in Stock

Jasper Juinen/Bloomberg News

Tesla Inc. agreed to acquire battery-technology company Maxwell Technologies Inc. for about $218 million in stock, as Elon Musk’s electric-car maker adds expertise in energy storage and power delivery.

The purchase price of $4.75 a share, announced by Maxwell in a statement Feb. 4, amounts to about a 55% premium to the target’s closing price Feb. 1.

The companies share a common goal, Maxwell CEO Franz Fink said in the statement. The deal will allow Maxwell shareholders “to participate in Tesla’s mission of accelerating the advent of sustainable transport and energy.”

Tesla shares wiped out their premarket gains and were down less than 1% to $311.90 in early trading after the announcement. Maxwell shares were halted on the news.
