 British electric-vehicle startup Arrival will go public by combining with a US blank check company set up by Peter Cuneo, the former CEO of Marvel Comics and personal care firm Remington Products. The deal would value the combined company at 5.4 billion and is expected to raise a total of 660 million, Arrival said in a statement. The electric bus-and-van maker was last valued at 3 billion after receiving a 118 million investment from BlackRock.
