       Registration Statement on Form S-1 filed April 21, 2021

       If we are a passive foreign investment company (PFIC)..., page 88

   1.                                                   Please revise the risk
factor heading and the disclosure on page 10 to state, if true, that
                                                        there is substantial
uncertainty regarding your current and future status under the Code.
                                                        We further note your
disclosure on page 89 indicating that your operations currently
                                                        generate very limited
amounts of non-passive income. To the extent that you believe it is
                                                        probable that you will
be a PFIC in 2021, please revise both the risk factor and Summary

revise the risk factor disclosure to explain the consequences to
                                                        stockholders if one or
more of of the Centessa Subsidiaries are treated as a PFIC.

2.    We refer to prior comment 20 and reissue. In this regard, the timing,
costs and funding
      associated with the infrastructure expansion remains unclear and it does
not appear that
      any offering proceeds are intended to cover these expenses. In light of
the disclosure on
      page 2 and elsewhere concerning the importance of having centralized
resources, please
      revise to provide additional details concerning these plans.

referenced on

4.    Please expand your description of the incentivization agreements to
disclose the
