revenue in this
         summary section.

Risks Related to MAAC and the Business Combination, page 98

completion of a business

less favorable
         company or on term less favorable to shareholders rather than
liquidate.
7.       Please highlight the sponsors and public shareholders have different
rates of return and
         clarify if the sponsors and affiliates can earn a positive rate of
return on their investment,
         even if the other SPAC shareholders experience a negative rate of
return in the post
         business combination company.

Acquisition of Silicon Therapeutics, page F-95

24.      We note that in March 2021 Roivant acquired Silicon Therapeutics, LLC
for consideration
         of approximately $450.0 million, with additional cash payments payable
subject to the
         satisfaction of certain regulatory and commercial milestones. Please
tell us why the
         financial statements of Silicon Therapeutics are not significant to
Roivant's financial
         statements such that the omission of those financial statements
renders Roivant's financial
         statements substantially incomplete or misleading. In this regards,
also please tell us your
         consideration of including the acquisition in the pro forma
information on page 163.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
