Mergers and Acquisitions LIFE SCIENCES

With decades of experience advising on all aspects of mergers and acquisitions, WilmerHale is the go-to firm for life sciences companies.

Mergers and acquisitions are prevalent in the life sciences industry because of the consolidating nature of the industry, and because of the importance of acquisitions as an exit strategy for biotechnology investors. We have significant experience in representing public and private clients in all types of M&A transactions, including stock-for-stock mergers, cash mergers, tender offers, acquisitions and dispositions of divisions, product lines and spin-offs. We also have particular knowledge and experience with milestone-based life sciences deals.

When it comes to mergers and acquisitions, our clients benefit from the broad range of relevant skills—securities, patent, regulatory, tax and antitrust/competition—that our attorneys bring to bear. In 2016, we advised clients throughout the United States and Europe on more than 75 M&A transactions, providing guidance across industries in areas including corporate, securities, antitrust and tax. Since 2006, we have participated in more than 1,000 mergers and acquisitions with a total value in excess of $400 billion, ranging from sales of VC-backed companies to multibillion-dollar global mergers.
