In the version of this article initially published, in the table titled “Notable Q1 biotech deals,” under Mergers and acquisitions, Warburg Pincus was incorrectly given as the Target and Lifecore Biomedical as the Acquirer. In fact, Warburg Pincus was the Acquirer and Lifecore Biomedical the Target. The error has been corrected in the HTML and PDF versions of the article.
