Greenvision Acquisition Corp. is the latest special purpose acquisition company to go hunting for a business combination in China, Asia or North America. The SPAC s registration became public Oct. 21 and calls for the alternative investment vehicle to raise up to $57.5 million in an initial public offering in order to pursue an acquisition of a life science or healthcare company. The new company has given itself a short runway to get a deal done, allowing just 12 months following the initial public offering, which is being underwritten by I-Bankers Securities Inc.
