Opinion on the financial statements 

We  have  audited  the  accompanying  consolidated  balance  sheet  of  Anthropic,  PBC  (a  Delaware  public  benefit 
corporation) and subsidiaries (the “Company”) as of December 31, 2024, the related consolidated statements of 
operations,  comprehensive  loss,  redeemable  convertible  preferred  stock  and  stockholders’  deficit,  and  cash 
flows for each of the years ended December 31, 2024 and 2023, and the related notes (collectively referred to as 
the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in 
all  material  respects,  the  financial  position  of  the  Company  as  of  December  31,  2024,  and  the  results  of  its 
operations and its cash flows for the years ended December 31, 2024 and 2023, in conformity with accounting 
principles generally accepted in the United States of America. 

Basis for opinion 

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our 
responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. 
We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United 
States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. 
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and 
the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 
and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of 
material  misstatement,  whether  due  to  error  or  fraud.  The  Company  is  not  required  to  have,  nor  were  we 
engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  As  part  of  our  audits  we  are 
required  to  obtain  an  understanding  of  internal  control  over  financial  reporting  but  not  for  the  purpose  of 
expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal control  over  financial  reporting. 
Accordingly, we express no such opinion. 

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial 
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made 
by management, as well as evaluating the overall presentation of the financial statements. We believe that our 
audits provide a reasonable basis for our opinion.
