Romeo Systems, which operates as Romeo Power Technology, will use the proceeds for capacity expansion and research and development to further develop battery system technologies for commercial vehicles, according to a statement.
After the deal closes, which is expected in the fourth quarter of 2020, the combined company will list on the New York Stock Exchange under the symbol “RMO”.

A SPAC is a shell company that raises money through an initial public offering to buy an operating entity, typically within two years.
SPACs have emerged as a quick route to the stock market for companies, particularly auto technology startups, and have proven popular with investors seeking to echo Tesla’s high stock valuation.
Other EV companies with SPAC deals include Fisker, Lordstown Motors and Canoo. Electric and fuel cell vehicle startup Nikola also went public via SPAC deal earlier in 2020.
