Where You Can Find Additional Information 

We have submitted with the SEC a registration statement on Form S-1 under the Securities Act with respect to 
the shares of our Class A common stock offered by this prospectus. This prospectus, which constitutes a part of 
the registration statement, does not contain all of the information set forth in the registration statement, some 
of which is contained in exhibits to the registration statement as permitted by the rules and regulations of the 
SEC. For further information with respect to us and our Class A common stock, we refer you to the registration 
statement,  including  the  exhibits  filed  as  a  part  of  the  registration  statement.  Statements  contained  in  this 
prospectus  concerning  the  contents  of  any  contract  or  any  other  document  are  not  necessarily  complete.  If  a 
contract  or  document  has  been  filed  as  an  exhibit  to  the  registration  statement,  please  see  the  copy  of  the 
contract or document that has been filed. Each statement in this prospectus relating to a contract or document 
filed  as  an  exhibit  is  qualified  in  all  respects  by  the  filed  exhibit.  The  SEC  maintains  a  website  that  contains 
reports, proxy and information statements, and other information about issuers, like us, that file electronically 
with the SEC. The address of that website is www.sec.gov.

As  a  result  of  this  offering,  we  will  become  subject  to  the  information  and  reporting  requirements  of  the 
Exchange Act and, in accordance therewith, will file periodic reports, proxy statements, and other information 
with  the  SEC.  We  also  maintain  a  website  at  www.anthropic.com.  Upon  completion  of  this  offering,  you  may 
access these materials free of charge as soon as reasonably practicable after they are electronically filed with, or 
furnished to, the SEC. Information contained on our website is not a part of this prospectus and the inclusion of 
our website address in this prospectus is an inactive textual reference only.
