Electric-vehicle start-up Canoo Holdings is going public: The company said on Tuesday that it will merge with a publicly traded special-purpose acquisition company (SPAC) in a deal similar to the one that took electric-semi start-up Nikola (NASDAQ: NKLA) public in June. The combined company will be called Canoo, Inc., once the merger with SPAC Hennessy Capital Acquisition IV (NASDAQ: HCAC.U) closes in the fourth quarter of 2020. The deal, which values Canoo at $2.4 billion, will raise about $600 million in cash.
