we do not cover, reimburse, or otherwise “gross-up” any income tax due from any applicable executive on such 
compensation.

Except as noted in the subsection below titled “Security Services,” none of our NEOs were provided with private 
aviation services for personal travel in 2025. 

Security Services 

The  protection  of  our  senior  leadership  is  a  critical  priority  for  our  company  and  our  stockholders.  In 
connection with our security program and our evaluation of security threats, we offer security services to certain 
of our NEOs and may provide security services to other NEOs in the future. Such security services may include: 
(i) individual protection services (including the protection of family members) and home security systems and 
monitoring, (ii) private aviation, and (iii) private car and driver services. These safeguards are implemented due 
to  the  variety  of  business-related  security  concerns  faced  by  our  senior  leaders,  and  they  are  comparable  to 
those provided to senior leaders of comparable high-profile companies in the technology industry. 

In 2025, a leading security consulting firm conducted independent, third-party security studies regarding the 
personal  and  security  risks  of  our  Chief  Executive  Officer  and  our  President.  Based  on  these  security  studies, 
increased  media  attention  for  Anthropic,  and  the  identification  of  bona  fide  business-related,  heightened 
security  concerns  arising  as  a  result  of  the  respective  positions  of  Dr.  Amodei  and  Ms.  Amodei  within  the 
company,  our  board  of  directors  determined  that  enhanced  personal  security  services  were  necessary  to 
increase  the  safety  and  protection  of  Dr.  Amodei  and  Ms.  Amodei,  and  to  avoid  an  impact  to  our  business 
continuity  if  a  security  incident  occurred.  Our  board  of  directors  regularly  assesses  security  concerns  and 
reviews the security services provided to Dr. Amodei and Ms. Amodei and the cost of such services in light of 
such concerns, and other benefits to our company. The security measures for Dr. Amodei and Ms. Amodei in 
2025  included  (i)  individual  protection  services  (including  during  personal  travel),  which  included  the 
protection of family members, as well as enhanced home security systems and surveillance, (ii) private car and 
driver services for ground transportation, and (iii) in the case of Dr. Amodei, the use of private aircraft for both 
business and personal travel.

Given the importance of the roles of Dr. Amodei and Ms. Amodei at Anthropic, our board of directors required 
the security measures described above for the benefit of our company, and we view the costs of these services as 
necessary and appropriate. In the “All Other Compensation” column of the Summary Compensation Table, we 
have  disclosed  the  aggregate  incremental  cost  of  the  security  benefits  that  may  be  deemed  to  be  perquisites 
under current relevant disclosure rules. We did not pay expenses for personal security for any other NEOs in 
2025, except in connection with business-related travel.

Health and Welfare Benefits

During 2025, we provided the following benefits to our NEOs on the same basis as our other eligible employees: 
medical; dental; vision; flexible spending account; health savings account; life insurance; short-term and long-
term disability insurance; fertility benefits; mental well-being benefits; health and wellness timesaver stipend; 
work from home stipend; education assistance program; commuting allowance; and a 401(k) retirement plan 
with employer match.
