As IPOs have slowed significantly in 2022, so have the debuts of special purpose acquisition companies (SPACs) targeting the life sciences industry, primarily due to two looming threats. This time a year ago, BioWorld had tracked 60 IPOs of SPACs searching for biopharma or med-tech targets and nearly 30 SPACs that had secured acquisitions. For 2022, there are 21 SPACs currently searching, and only two of those went public this year. As for completed M&As involving SPACs, there have been 17 this year and another nine that are pending.
