OmniAb (Avista Public Acquisition II) ^{Priced, Nasdaq: OABI}

We are a newly organized blank check company incorporated on February 5, 2021 as a Cayman Islands exempted company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses, which we refer to throughout this prospectus as our initial business combination. We have not identified any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with respect to identifying any business combination target. We intend to source investment opportunities through our team’s extensive network of healthcare industry executives, board members, private equity investors, wealthy families, commercial banks, investment bankers, advisors, attorneys, accountants and other transaction intermediaries to identify potential investment opportunities. We believe this approach will yield a large number of acquisition candidates. Avista’s distinctive healthcare focused network, coupled with its proactive approach to sourcing, has provided our management team and directors with a flow of referrals that have resulted in numerous transactions for Avista, several of which were proprietary and not available to generalist or less focused participants.
